Full Text Available Recurrent haze in Southeast Asian countries including Singapore is largely attributable to rampant forest fires in Indonesia due to, for example, extensive slash-and-burn (S & B culture. Drawing on the “treadmill of production” and environmental governance approach, we examine causes and consequences of this culture. We found that, despite some perceived benefits, its environmental consequences include deforestation, soil erosion and degradation, global warming, threats to biodiversity, and trans-boundary haze pollution, while the societal consequences comprise regional tension, health risks, economic and productivity losses, as well as food insecurity. We propose sustainability through a plural coexistence framework of governance for targeting S & B that incorporates strategies of incentives, education and community resource management.

Current policies, strategies and aspects of environmental impact assessment in a transboundary context

International Nuclear Information System (INIS)

1996-01-01

Environmental impact assessment (EIA) has already shown its value for implementing and strengthening sustainable development, as it combines the precautionary principles with the principle of preventing environmental damage and also arranges for public participation. EIA is already used as an effective instrument for improving the quality of the environment at the national level and it is understood that the EIA Convention will lead to environmentally sound and sustainable development by providing information on the interrelationship between economic activities and their environmental consequences in particular in a transboundary context. The Convention obliges Parties to assess the environmental impacts at an early stage of planning and includes measures and procedures to prevent, control or reduce any significant adverse effect on the environment, particularly any transboundary effect, which is likely to be caused by a proposed activity or any major change to an existing activity

Process Review for Development of Quantitative Risk Analyses for Transboundary Animal Disease to Pathogen-Free Territories

Directory of Open Access Journals (Sweden)

Jonathan Miller

2017-10-01

Full Text Available Outbreaks of transboundary animal diseases (TADs have the potential to cause significant detriment to animal, human, and environmental health; severe economic implications; and national security. Challenges concerning data sharing, model development, decision support, and disease emergence science have recently been promoted. These challenges and recommendations have been recognized and advocated in the disciplines intersecting with outbreak prediction and forecast modeling regarding infectious diseases. To advance the effective application of computation and risk communication, analytical products ought to follow a collaboratively agreed common plan for implementation. Research articles should seek to inform and assist prioritization of national and international strategies in developing established criteria to identify and follow best practice standards to assess risk model attributes and performance. A well-defined framework to help eliminate gaps in policy, process, and planning knowledge areas would help alleviate the intense need for the formation of a comprehensive strategy for countering TAD outbreak risks. A quantitative assessment that accurately captures the risk of introduction of a TAD through various pathways can be a powerful tool in guiding where government, academic, and industry resources ought to be allocated, whether implementation of additional risk management solutions is merited, and where research efforts should be directed to minimize risk. This review outlines a part of a process for the development of quantitative risk analysis to collect, analyze, and communicate this knowledge. A more comprehensive and unabridged manual was also developed. The framework used in supporting the application of aligning computational tools for readiness continues our approach to apply a preparedness mindset to challenges concerning threats to global biosecurity, secure food systems, and risk-mitigated agricultural economies.

Tyagi, H.; Gosain, A. K.; Khosa, R.

2017-12-01

Climate uncertainty & perpetually rising freshwater demands have emerged as the biggest threat to global water security. Consequently, water disputes have become more frequent & intense. If such conflicts remain unresolved for long, eventually they may cause severe socio-political damage to the riparians. The present study develops a comprehensive framework for conflict resolution & equitable allocation in transboundary Ganges watercourse with 4 stakeholder nations: China (Tibet), Nepal, India & Bangladesh. Scientific spatio-temporal information can be of great help in transboundary dispute resolution. Hence, this study employs a GIS-based semi-distributed SWAT hydrologic model for estimating water balance at different scales within the basin for present & future climate, landuse, storage & water use efficiency scenarios. The study analyses pertinent provisions of the Indian Constitution & examines the rulings of Indian water tribunals. It also critically compares various water dispute resolution mechanisms & doctrines on the barometer of equity & fairness to arrive at a procedurally & distributionally just water apportionment policy. The study makes use of Methods of Apportionments, Operations Research & Bankruptcy Rules to operationalize the chosen doctrine by devising an objective & quantifiable formulae for water allocation amongst the co-basin states for a range of flows. Furthermore, Game Theoretic and multi-optimization techniques have been used to rank the appropriateness of the above mentioned methods according to aggregate satisfaction/resentment of the stakeholders computed by equating their respective water claims with actual water shares obtained by them under different methods. Moreover, several Social Choice Theory methods have been employed to rate the performance of water allotment methods in a socio-political setting. The developed framework can thus be of great help for decision makers in effective water conflict resolution as transboundary

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

2016-04-01

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

Central Europe has experienced environmental degradation for hundreds of years. The proximity of countries, their shared resources, and transboundary movement of environmental pollution, create the potential for regional environmental strife. The goal of this project was to identify the sources and sinks of environmental pollution in Central Europe and evaluate the possible impact of transboundary movement of pollution on the countries of Central Europe. In meeting the objectives of identifying sources of contaminants, determining transboundary movement of contaminants, and assessing socio-economic implications, large quantities of disparate data were examined. To facilitate use of the data, the authors refined mapping procedures that enable processing information from virtually any map or spreadsheet data that can be geo-referenced. Because the procedure is freed from a priori constraints of scale that confound most Geographical Information Systems, they have the capacity to generate new projections and apply sophisticated statistical analyses to the data. The analysis indicates substantial environmental problems. While transboundary pollution issues may spawn conflict among the Central European countries and their neighbors, it appears that common environmental problems facing the entire region have had the effect of bringing the countries together, even though opportunities for deteriorating relationships may still arise.

The ECE Convention on Environmental Impact Assessment in a Transboundary Context (EIA Convention) is the first multilateral treaty to specify the procedural rights and duties of Parties with regard to transboundary impacts of proposed activities and to provide procedures, in a transboundary context, for the consideration of environmental impacts in decision-making. The EIA Convention, elaborated under the auspices of the United Nations Economic Commission for Europe (ECE), was adopted at Espoo, Finland, in February 1991. Obligations stipulated, and measures and procedures provided for in this Convention are described. (author)

Laws, Institutions and Transboundary Pasture Management in the High Pamir and Pamir-Alai Mountain Ecosystem of Central Asia

Directory of Open Access Journals (Sweden)

Michelle Lim

2012-06-01

Full Text Available Enhanced rangeland governance is a priority for the governments of the post-Soviet Central Asian states of the Kyrgyz Republic and Tajikistan. Major transitional challenges confront the newly independent states of Central Asia. These challenges include the withdrawal of subsidies previously provided by the centralised Soviet government; moves towards privatisation and the conversion of administrative boundaries to international boundaries. In this context transboundary approaches to rangeland management are essential. This paper highlights the challenges for effective pasture management in the Pamir, Pamir-Alai ecosystem; the inadequacies of pasture-related legal instruments and the absence of institutions for the implementation of these instruments. Transboundary management is hampered by the lack of agreements between the two countries and the differences between national level laws and institutions. Meaningful transboundary agreements and the harmonization of national level laws would be a significant step towards achieving sustainable transboundary pasture management. However, on their own these legal tools are insufficient. Long-term effective pasture management in the Pamir, Pamir-Alai ecosystem necessitates that the causes of degradation are addressed. Mountain communities would also need to be convinced of economic and other benefits before current resource-use practices could be expected to change. Institutional and capacity building and adequate funding are also fundamental to ensuring the effectiveness of any legal instruments that are developed and any strategies that are employed.

Legal approaches to transboundary pollution - relating to nuclear activities

International Nuclear Information System (INIS)

Hintsteiner, G.

2000-05-01

This work examines the legal approaches to pollution in a transboundary context. Particular consideration is given to transboundary pollution that is related to the use of nuclear energy for peaceful purposes. Since I have chosen to approach the very topic not so much in the hope of finding a single and unequivocal answer but rather by building a circumstantial case, the present work naturally relies to a great extent on decisions of international courts and tribunals, as well as on principles and rules stemming from international law in general. The international norm that basically guides the topic is the prohibition of transboundary pollution, or, expressed as a positive duty, i.e. the obligation to prevent transboundary harm, which has found expression in Principle 21 of the Stockholm Declaration on the Human Environment. The very obligation is relevant from the perspective of prevention of environmental harm, as well as reparation when harm has actually occurred. One of the primary issues of this work accordingly relates to the obligation's preventive function, thus its extent, meaning and scope are examined, and in particular its approach to transboundary risk-creation. In the overall context of transboundary pollution the principle of the sovereign equality of states and other basic rules that directly emanate from it are of continuos importance. This work is further strongly impacted by notions of equity together with the establishment of a balancing of interests test which application merits special consideration in cases where a conflict between two states cannot be solved by mere reliance on their sovereign rights. Rules relating to the prevention of environmental harm, now increasingly guided by the Precautionary Principle, are also relevant under the law of state responsibility for wrongful acts and in the context of defining obligations erga omnes.

2017-10-01

Flood disaster is one of the heaviest disasters in the world. It is necessary to monitor and evaluate the flood disaster in order to mitigate the consequences. As floods do not recognize borders, transboundary flood risk management is imperative in shared river basins. Disaster management is highly dependent on early information and requires data from the whole river basin. Based on the hypothesis that the flood events over the same area with same magnitude have almost identical evolution, it is crucial to develop a repository database of historical flood events. This tool, in the case of extended transboundary river basins, could constitute an operational warning system for the downstream area. The utility of SAR images for flood mapping, was demonstrated by previous studies but the SAR systems in orbit were not characterized by high operational capacity. Copernicus system will fill this gap in operational service for risk management, especially during emergency phase. The operational capabilities have been significantly improved by newly available satellite constellation, such as the Sentinel-1A AB mission, which is able to provide systematic acquisitions with a very high temporal resolution in a wide swath coverage. The present study deals with the monitoring of a transboundary flood event in Evros basin. The objective of the study is to create the "migration story" of the flooded areas on the basis of the evolution in time for the event occurred from October 2014 till May 2015. Flood hazard maps will be created, using SAR-based semi-automatic algorithms and then through the synthesis of the related maps in a GIS-system, a spatiotemporal thematic map of the event will be produced. The thematic map combined with TanDEM-X DEM, 12m/pixel spatial resolution, will define the non- affected areas which is a very useful information for the emergency planning and emergency response phases. The Sentinels meet the main requirements to be an effective and suitable

Transboundary river basin management in Europe
Legal instruments to comply with European water management obligations in case of transboundary water pollution and floods

Full Text Available Although modern European water policy follows a river basin approach where Member States have to cooperate in order to achieve a ‘good status’ of their water bodies, the obligations arising from the European water directives are to be achieved by each Member State individually. This situation creates problems when water pollution and water quantity problems cross borders. It is still unclear whether Member States can be held responsible for not achieving objectives due to causes (partly originating abroad. This article describes some of the legal instruments that water authorities have at their disposal to comply with the European water management obligations in case of transboundary water pollution and floods and thus shape transboundary river management. The article describes instruments to create, implement and enforce transboundary cooperation, and addresses the possibility of transboundary compensation if cooperation fails. Here, the focus is on a civil lawsuit before a domestic court.

Implementing the Espoo Convention in transboundary EIA between Germany and Poland

International Nuclear Information System (INIS)

Albrecht, Eike

2008-01-01

Poland and Germany have a long common border which leads to the necessity to cooperate and consult each other in the case of large-scale projects or infrastructure measures likely to cause negative transboundary effects on the environment. There are already binding provisions for transboundary EIA. In the area of the UN Economic Commission for Europe (UNECE), transboundary EIA is intended to be legally binding for the Member States by the Espoo Convention which was ratified by Germany 8.8.2002 and by Poland 12.6.1997. Due to corresponding directives, the same is applicable in the context of the European Union. In German legislation, this issue is regulated by Art. 8 of the Federal EIA Act in regard to transboundary participation of administration and by Art. 9a in respect of transboundary public participation. However, these EIA regulations on transboundary participation do not surpass a certain detail level, as they have to be applied between Germany and all neighbouring states. Therefore both countries decided to agree on more detailed provisions in particular regarding procedural questions. During the 12th German-Polish Environmental Council, Germany and Poland reached an agreement on 11.4.2006 in Neuhardenberg/Brandenburg an agreement upon the implementation of the Espoo Convention, the so called Neuhardenberg Agreement. This article assesses the agreement under consideration of already existing law and discusses major improvements and problems

This paper investigates a second-best trade agreement between two countries that takes the distortion arising from their non-coordinated environmental policies into consideration. In a reciprocal-markets model with bidirectional transboundary pollution, we find that if the transboundary pollution is sufficiently strong, the second-best trade agreement requires that both countries subsidize the imported goods whose consumption gives rise to pollution. We also find that a bilateral tariff reduction is beneficial to the global environment. (author)

Response to a radioactive materials release having a transboundary impact

International Nuclear Information System (INIS)

1989-01-01

Compared with an accidental release of radioactive material which is confined to the accident State, a transboundary release has added dimensions which were not fully anticipated in publications dealing with response to accidents at nuclear facilities. The new aspects to the problem may be summarized as follows: (1) A transboundary release of radioactive material, as distinct from a release which affects only the accident State, has international repercussions in the following ways: Potentially at least, the difficulties associated with a transboundary release may be magnified in those States that have no nuclear facilities of their own and may, therefore, have foreseen no need for resources to assess and deal with radioactive contamination of their food supplies, their water and their environment appropriately. International trade, in food commodities particularly, may be severely affected. Issues of compensation may arise for which the dispute settlement mechanisms are weak or non-existent. (2) Many Member States are in such geographic locations that they could be affected by a transboundary release occurring in any of their surrounding neighbour States. Planning for and responding to such an event is necessarily more difficult than planning for an accidental release from a single, identified nuclear facility. (3) Deposits of radioactive material from a distant source are apt to be highly unpredictable. Depending on weather conditions, they may be localized in a random fashion or widespread. Because of the international dimension of the problem and its essentially unpredictable character it is recommended here that planning for such events should be carried at the national or federal government level rather than at provincial government level. 14 refs

Non-transboundary pollution and the efficiency of international environmental co-operation

The increased awareness of the transboundary pollution problems resulted in a number of international treaties, such as the Montreal protocol on ozone-depleting substances (1987), and the Basel Convention on hazardous waste (1989). Most authors writing on efficient environmental instruments make a sharp distinction between domestic and transboundary environmental problems. While the former should be abated by domestic environmental instruments, an efficient treatment of the latter requires international instruments. The underlying logic is that in case of non-transboundary pollution both the costs and benefits of environmental policies are strictly domestic, the trade-off between benefits and costs of abatement should also be a strictly domestic issue. In contrast, with transboundary pollution the trade-off between abatement costs and benefits becomes an international issue. In this paper we analyse four cases where international environmental co-ordination is required to achieve an efficient outcome, even though the environmental externality is non-transboundary in nature. Section two sketches the standard view on efficient intervention levels with regard to transborder and non-transborder pollution. In the third section we deal with cases where environmental policy is used in a trade-strategic way. The section pays attention to the motives for using domestic environmental policy as a disguise for trade policies. It will be argued that the resulting allocative efficiency can be improved upon by international co-operation. Sections 4-6 analyse three cases where international co-operation may improve the international outcome on the basis of non-coordinated domestic allocation decisions. These cases refer in particular to the situation of developing countries, when there is a high export dependency on the polluting good in combination with the existence of discrete technologies, set-up costs of environment-friendly technologies, and the existence of increasing

Unraveling the disease consequences and mechanisms of modular structure in animal social networks

Disease risk is a potential cost of group living. Although modular organization is thought to reduce this cost in animal societies, empirical evidence toward this hypothesis has been conflicting. We analyzed empirical social networks from 43 animal species to motivate our study of the epidemiological consequences of modular structure in animal societies. From these empirical studies, we identified the features of interaction patterns associated with network modularity and developed a theoretical network model to investigate when and how subdivisions in social networks influence disease dynamics. Contrary to prior work, we found that disease risk is largely unaffected by modular structure, although social networks beyond a modular threshold experience smaller disease burden and longer disease duration. Our results illustrate that the lowering of disease burden in highly modular social networks is driven by two mechanisms of modular organization: network fragmentation and subgroup cohesion. Highly fragmented social networks with cohesive subgroups are able to structurally trap infections within a few subgroups and also cause a structural delay to the spread of disease outbreaks. Finally, we show that network models incorporating modular structure are necessary only when prior knowledge suggests that interactions within the population are highly subdivided. Otherwise, null networks based on basic knowledge about group size and local contact heterogeneity may be sufficient when data-limited estimates of epidemic consequences are necessary. Overall, our work does not support the hypothesis that modular structure universally mitigates the disease impact of group living.

River basins for which transboundary coordination and governance is a factor are of concern to US national security, yet there is often a lack of sufficient data-driven information available at the needed time horizons to inform transboundary water decision-making for the intelligence, defense, and foreign policy communities. To address this need, a two-day workshop entitled Transboundary Water: Improving Methodologies and Developing Integrated Tools to Support Global Water Security was held in August 2017 in Maryland. The committee that organized and convened the workshop (the Organizing Committee) included representatives from the National Aeronautics and Space Administration (NASA), the US Army Corps of Engineers Engineer Research and Development Center (ERDC), and the US Air Force. The primary goal of the workshop was to advance knowledge on the current US Government and partners' technical information needs and gaps to support national security interests in relation to transboundary water. The workshop also aimed to identify avenues for greater communication and collaboration among the scientific, intelligence, defense, and foreign policy communities. The discussion around transboundary water was considered in the context of the greater global water challenges facing US national security.

Animal personality as a cause and consequence of contest behaviour.

Briffa, Mark; Sneddon, Lynne U; Wilson, Alastair J

2015-03-01

We review the evidence for a link between consistent among-individual variation in behaviour (animal personality) and the ability to win contests over limited resources. Explorative and bold behaviours often covary with contest behaviour and outcome, although there is evidence that the structure of these 'behavioural syndromes' can change across situations. Aggression itself is typically repeatable, but also subject to high within-individual variation as a consequence of plastic responses to previous fight outcomes and opponent traits. Common proximate mechanisms (gene expression, endocrine control and metabolic rates) may underpin variation in both contest behaviour and general personality traits. Given the theoretical links between the evolution of fighting and of personality, we suggest that longitudinal studies of contest behaviour, combining behavioural and physiological data, would be a useful context for the study of animal personalities. © 2015 The Author(s) Published by the Royal Society.

The Role of Transnational Municipal Networks in Transboundary Water Governance

Directory of Open Access Journals (Sweden)

Savitri Jetoo

2017-01-01

Full Text Available The transboundary nature of stressors impacting shared water bodies has been traditionally recognized in agreements between nation states. Several developments have led to new layers of cross border environmental actors, including regional and city level interactions. This proliferation of non-state actors is witnessed in two large water bodies, the Baltic Sea and the North American Great Lakes. In both regions, transboundary water governance was led by nation states in agreements to improve heavily contaminated waters, the Helsinki Convention (1974 and the North American Great Lakes Water Quality Agreement (1972, respectively. Whilst there has been much research on transnational regional networks, especially in Europe, there has been less theoretical work done on transnational municipal transboundary water networks due to the delay of recognition of the legitimacy of these local government actors. This paper aims to examine the role of the transnational municipal networks in transboundary water governance by looking at the case studies of the Union of Baltic cities in the Baltic Sea region and the Great Lakes and St. Lawrence Cities Initiative in the North American Great Lakes Basin. It does this by assessing the role of these transnational municipal networks in bridging water governance gaps in these regions.

Assessing Management Regimes in Transboundary River Basins: Do They Support Adaptive Management?

Directory of Open Access Journals (Sweden)

G.T. (Tom Raadgever

2008-06-01

Full Text Available River basin management is faced with complex problems that are characterized by uncertainty and change. In transboundary river basins, historical, legal, and cultural differences add to the complexity. The literature on adaptive management gives several suggestions for handling this complexity. It recognizes the importance of management regimes as enabling or limiting adaptive management, but there is no comprehensive overview of regime features that support adaptive management. This paper presents such an overview, focused on transboundary river basin management. It inventories the features that have been claimed to be central to effective transboundary river basin management and refines them using adaptive management literature. It then collates these features into a framework describing actor networks, policy processes, information management, and legal and financial aspects. Subsequently, this framework is applied to the Orange and Rhine basins. The paper concludes that the framework provides a consistent and comprehensive perspective on transboundary river basin management regimes, and can be used for assessing their capacity to support adaptive management.

Transboundary Movement of Radioactively Contaminated Scrap Metal - Lessons Learned

Starting in 1989, Bulgaria has undergone a comprehensive transformation of its economy and social conditions. Part of this process is related to the intensive privatization that started in 2001. This privatization included facilities, as well as sites that use radioactive material for different applications - industry, medicine, agriculture, science, etc. The rapid change of property ownership and, in some cases, the resulting bankruptcy, has caused difficulties in tracing and identifying radioactive sources and materials and a deterioration of the system of safety, physical protection, etc. of radioactive material. In some cases, radioactive sources were stolen because of the value of their protective containers and sold for scrap metal. This led to the occurrence of different types of radiation incidents, mainly related to the discovery of radioactive sources in scrap metal. The consequences of these incidents include the risk of radiation exposure of the workers at scrap metal yards or reprocessing facilities and of members of the public and, in addition, radioactive contamination of the environment. The Bulgarian Nuclear Regulatory Agency (BNRA) has been responding to these incidents and has carried out a series of measures to improve the control over materials (e.g. activated or surface contaminated materials) and radioactive sources and to strengthen the preventive, monitoring, emergency preparedness and mitigating measures at facility, national and transboundary levels. This paper presents an analysis of the lessons learned by the BNRA and of the control of the transboundary movement of radioactively contaminated scrap metal through the territory of Bulgaria.

Gathering the efficient information on water pollution of transboundary river systems remains the crucial task in international water management, environmental pollution control and prevention health problems. Countries, located in the low parts of the river basins, depend on the water strategy and water use in the adjacent countries, located upstream. Surface water pollution is considered to be the most serious problem, facing the above-mentioned countries. Large efforts in terms of field measurement campaigns and (numerical) transport modeling are then typically needed for relevant pollution prediction and prevention. Russian rivers take inflow from 8 neighboring countries. Among them there are 2 developing economies - People Republic of China and Mongolia, which are located in water-scarce areas and thus solve their water-related problems through the consumption of international water. Negative change of water runoff and water quality in the foreign part of transboundary river is appeared inside Russian territory with more or less delay. The transboundary river system of Selenga is particularly challenging, being the biggest tributary of Lake Baikal which is the largest freshwater reservoir in the world. Selenga River contributes about 50 % of the total inflow into Baikal. It originates in the mountainous part of Mongolia and then drains into Russia. There are numerous industries and agricultural activities within the Selenga drainage basin that affect the water quality of the river system. Absence of the single monitoring system and predictive tools for pollutants transport in river system requires large efforts in understanding sources of water pollution and implemented data on the relevant numerical systems for the pollution prediction and prevention. Special investigations in the Selenga river basin (Mongolia and Russia) were done to assess hot spots and understand state-of-the art in sediment load, water chemistry and hydrobiology of transboundary systems

Resilience in Transboundary Water Governance: the Okavango River Basin

Directory of Open Access Journals (Sweden)

Olivia O. Green

2013-06-01

Full Text Available When the availability of a vital resource varies between times of overabundance and extreme scarcity, management regimes must manifest flexibility and authority to adapt while maintaining legitimacy. Unfortunately, the need for adaptability often conflicts with the desire for certainty in legal and regulatory regimes, and laws that fail to account for variability often result in conflict when the inevitable disturbance occurs. Additional keys to resilience are collaboration among physical scientists, political actors, local leaders, and other stakeholders, and, when the commons is shared among sovereign states, collaboration between and among institutions with authority to act at different scales or with respect to different aspects of an ecological system. At the scale of transboundary river basins, where treaties govern water utilization, particular treaty mechanisms can reduce conflict potential by fostering collaboration and accounting for change. One necessary element is a mechanism for coordination and collaboration at the scale of the basin. This could be satisfied by mechanisms ranging from informal networks to the establishment of an international commission to jointly manage water, but a mechanism for collaboration at the basin scale alone does not ensure sound water management. To better guide resource management, study of applied resilience theory has revealed a number of management practices that are integral for adaptive governance. Here, we describe key resilience principles for treaty design and adaptive governance and then apply the principles to a case study of one transboundary basin where the need and willingness to manage collaboratively and iteratively is high - the Okavango River Basin of southwest Africa. This descriptive and applied approach should be particularly instructive for treaty negotiators, transboundary resource managers, and should aid program developers.

Reducing hazards for animals from humans

Directory of Open Access Journals (Sweden)

Full Text Available If animals may be a source of hazards for humans, the reverse is equally true. The main sources of hazards from humans to animals, are the impact of human introduction of transboundary animal diseases, climate change, globalisation, introduction of invasive species and reduction of biodiversity.There is also a trend toward reducing genetic diversity in domestic animals, such as cattle; there are presently around 700 different breeds of cattle many of which at the verge of extinction (less than 100 reproductive females. The impact of humans is also indirect through detrimental effects on the environment. It is therefore urgent to implement the new concept of “one health"....

Currently important animal disease management issues in sub-Saharan Africa.

Science.gov (United States)

Thomson, G R

2009-03-01

The present international approach to management of transboundary animal diseases (TADs) is based on the assumption that most can be eradicated; consequently, that is the usual objective adopted by international organizations concerned with animal health. However, for sub-Saharan Africa and southern Africa more particularly, eradication of most TADs is impossible for the foreseeable future for a variety of technical, financial and logistical reasons. Compounding this, the present basis for access to international markets for products derived from animals requires that the area of origin (country or zone) is free from trade-influencing TADs. The ongoing development of transfrontier conservation areas (TFCAs), extending across huge areas of southern Africa, therefore presents a development conundrum because it makes creation of geographic areas free from TADs more difficult and brings development based on wildlife conservation on the one hand and that based on livestock production on the other into sharp conflict. Sub-Saharan Africa is consequently confronted by a complex problem that contributes significantly to retarded rural development which, in turn, impedes poverty alleviation. In southern Africa specifically, foot-and-mouth disease (FMD) presents the greatest problem in relation to access to international markets for animal products. However, it is argued that this problem could be overcome by a combination between (1) implementation of a commodity-based approach to trade in products derived from animals and (2) amendment of the international standards for FMD specifically (i.e. the FMD chapter in the Terrestrial Animal Health Code of the World Organisation for Animal Health [OIE]) so that occurrence of SAT serotype viruses in free-living African buffalo need not necessarily mean exclusion of areas where buffalo occur from international markets for animal products. This would overcome a presently intractable constraint to market access for southern African

Evolution, opportunity and challenges of transboundary water and energy problems in Central Asia.

Central Asia is one of the regions that suffer the most prominent transboundary water and energy problems in the world. Effective transboundary water-energy resource management and cooperation are closely related with socioeconomic development and stability in the entire Central Asia. Similar to Central Asia, Northwest China has an arid climate and is experiencing a water shortage. It is now facing imbalanced supply-demand relations of water and energy resources. These issues in Northwest China and Central Asia pose severe challenges in the implementation of the Silk Road Economic Belt strategy. Based on the analysis of water and energy distribution characteristics in Central Asia as well as demand characteristics of different countries, the complexity of local transboundary water problems was explored by reviewing corresponding historical problems of involved countries, correlated energy issues, and the evolution of inter-country water-energy cooperation. With references to experiences and lessons of five countries, contradictions, opportunities, challenges and strategies for transboundary water-energy cooperation between China and Central Asia were discussed under the promotion of the Silk Road Economic Belt construction based on current cooperation conditions.

Integrating global animal health, public health and tropical animal health issues into the veterinary curriculum: a South African/African perspective.

Swan, G E; Coetzer, J A W; Terblanche, H M

2009-08-01

The globalisation of trade and food, the increased volume and speed of international travel, climate change, and the related escalation of emerging and re-emerging infectious diseases mean that countries are now more interconnected and interdependent than ever before. Africa is beleaguered by a range of endemic infectious and parasitic tropical diseases which, due to its diverse wildlife populations and indigenous livestock, can serve as a reservoir of high-impact or transboundary diseases and play a role in the emergence of disease, particularly at the wildlife, domestic animal and human interfaces. It is therefore essential to integrate animal and public health issues into the veterinary curriculum. Veterinary training in most parts of sub-Saharan Africa has focused on producing veterinarians to serve the livestock sector although socio-economic changes and privatisation of Veterinary Services have caused curriculum adjustments, as have globalisation and the increased risk of the spread of transboundary diseases. In South Africa, undergraduate veterinary training is more clinically oriented than in other regions. Animal and public health issues are covered in the curriculum, although their global relevance is not emphasised. The authors describe the undergraduate veterinary curriculum and summarise post-graduate programmes in South Africa. They also discuss a more comprehensive core-elective approach to the current curriculum and the need to adapt to new challenges facing the profession. Finally, they examine the potential use of innovative technology in undergraduate and post-graduate training and professional development, the importance of regional and international collaboration and the accreditation and recognition of veterinary training.

Observations and modeling results were used to examine spatial scales and transport patterns of ozone pollution in the Ontario-New York region. - We investigated the effects of transboundary pollution between Ontario and New York using both observations and modeling results. Analysis of the spatial scales associated with ozone pollution revealed the regional and international character of this pollutant. A back-trajectory-clustering methodology was used to evaluate the potential for transboundary pollution trading and to identify potential pollution source regions for two sites: CN tower in Toronto and the World Trade Center in New York City. Transboundary pollution transport was evident at both locations. The major pollution source areas for the period examined were the Ohio River Valley and Midwest. Finally, we examined the transboundary impact of emission reductions through photochemical models. We found that emissions from both New York and Ontario were transported across the border and that reductions in predicted O 3 levels can be substantial when emissions on both sides of the border are reduced

A dynamic game of a transboundary pollutant with asymmetric players

Modeling transboundary pollutants in a dynamic game framework provides a foundation for analyzing the impact of various policy options. The focus of this analysis is on the results of a tax/subsidy scheme used to address the transboundary problem of global climate change. A nonzero-sum dynamic game with asymmetric players is used to evaluate the policy impact of the tax/subsidy scheme on the respective player's value functions and strategies as determined by a Nash equilibrium feedback solution. The asymmetry of the players is reflected in their respective attitudes toward global climate change with one player benefiting from the change and the other losing. 17 refs., 5 tabs

Sharing water and benefits in transboundary river basins

Science.gov (United States)

Arjoon, Diane; Tilmant, Amaury; Herrmann, Markus

2016-06-01

The equitable sharing of benefits in transboundary river basins is necessary to solve disputes among riparian countries and to reach a consensus on basin-wide development and management activities. Benefit-sharing arrangements must be collaboratively developed to be perceived not only as efficient, but also as equitable in order to be considered acceptable to all riparian countries. The current literature mainly describes what is meant by the term benefit sharing in the context of transboundary river basins and discusses this from a conceptual point of view, but falls short of providing practical, institutional arrangements that ensure maximum economic welfare as well as collaboratively developed methods for encouraging the equitable sharing of benefits. In this study, we define an institutional arrangement that distributes welfare in a river basin by maximizing the economic benefits of water use and then sharing these benefits in an equitable manner using a method developed through stakeholder involvement. We describe a methodology in which (i) a hydrological model is used to allocate scarce water resources, in an economically efficient manner, to water users in a transboundary basin, (ii) water users are obliged to pay for water, and (iii) the total of these water charges is equitably redistributed as monetary compensation to users in an amount determined through the application of a sharing method developed by stakeholder input, thus based on a stakeholder vision of fairness, using an axiomatic approach. With the proposed benefit-sharing mechanism, the efficiency-equity trade-off still exists, but the extent of the imbalance is reduced because benefits are maximized and redistributed according to a key that has been collectively agreed upon by the participants. The whole system is overseen by a river basin authority. The methodology is applied to the Eastern Nile River basin as a case study. The described technique not only ensures economic efficiency, but may

Munia, H.; Guillaume, J. H. A.; Mirumachi, N.; Porkka,M.; Wada, Yoshihide; Kummu, M.

Growing population and water demand have increased pressure on water resources in various parts of the globe, including many transboundary river basins. While the impacts of upstream water use on downstream water availability have been analyzed in many of these international river basins, this has not been systematically done at the global scale using coherent and comparable datasets. In this study, we aim to assess the change in downstream water stress due to upstream water use in the world's transboundary river basins. Water stress was first calculated considering only local water use of each sub-basin based on country-basin mesh, then compared with the situation when upstream water use was subtracted from downstream water availability. Wefound that water stress was generally already high when considering only local water use, affecting 0.95-1.44 billion people or 33%-51% of the population in transboundary river basins. After accounting for upstream water use, stress level increased by at least 1 percentage-point for 30-65 sub-basins, affecting 0.29-1.13 billion people. Altogether 288 out of 298 middle-stream and downstream sub-basin areas experienced some change in stress level. Further, we assessed whether there is a link between increased water stress due to upstream water use and the number of conflictive and cooperative events in the transboundary river basins, as captured by two prominent databases. No direct relationship was found. This supports the argument that conflicts and cooperation events originate from a combination of different drivers, among which upstream-induced water stress may play a role. Our findings contribute to better understanding of upstream-downstream dynamics in water stress to help address water allocation problems.

Control of Pollutants in the Trans-Boundary Area of Taihu Basin, Yangtze Delta

Directory of Open Access Journals (Sweden)

Full Text Available This work focuses on pollution control in the trans-boundary area of Taihu Basin. Considering the unique characteristics of the river network in the study area, a new methodology of pollution control is proposed aiming at improving the water quality in the trans-boundary area and reducing conflicts between up and downstream regions. Based on monitoring data and statistical analysis, important trans-boundary cross sections identified by the regional government were selected as important areas for consideration in developing management objectives; using a 1-D mathematicmodel and an effective weight evaluation model, the trans-boundary effective control scope (TECS of the study area was identified as the scope for pollutant control; the acceptable pollution load was then estimated using an established model targeting bi-directional flow. The results suggest that the water environmental capacity for chemical oxygen demand (COD, in order to guarantee reaching the target water quality standard in the TECS, is 160,806 t/year, and amounts to 16,098 t/year, 3493 t/year, and 39,768 t/year for ammonia nitrogen, total nitrogen, and total phosphorus, respectively. Our study method and results have been incorporated into the local government management project, and have been proven to be useful in designing a pollution control strategy and management policy.

The UNESCO-IHP ISARM-Americas technical committee has developed a regional strategy for the assessment and management of transboundary aquifer systems in the Americas as part of their ongoing cooperative assistance to help neighboring countries sustain water resources and reduce potential conflict. The fourth book in the series of publications sponsored by UNESCO and OAS documents this strategy. The goal of this strategy is the collective understanding, developing, managing, and protecting of the transboundary aquifers in the Americas This strategy includes technical, social, and governance recommendations for an integrated resource management of groundwater based on flexible arrangements that not only manage but also demand social participation in solving problems, consider changes in land use and water use and promote the increase of water sustainability for all transboundary neighbors. The successful implementation of this strategy starts with sharing information of the status and use of land and water as well as intergovernmental partnerships to link science and policy with existing instruments for managing the water resources. International organizations such as UNESCO and OAS also can help facilitate the development of transboundary agreements and establish cooperation on transboundary aquifers between neighbors. The UNESCO-IHP ISARM-Americas technical committee has been successful in creating a network of partners from 24 countries and in translating existing aquifer knowledge into a meaningful strategy for the American hemisphere. The strategy aims to explain and develop the role of science and the informed-decision approach. Examples from North and South America show how the process has begun to develop for selected transboundary aquifers. These include the Milk River basin between the US and Canada, the Rio Grande and Colorado River basins between the US and Mexico, and the Guarani River basin in South America.

Full text: The condition of the water resources of the Republic of Kazakhstan is characterized with their whole deficiency as well as their high pollution and desiccation. The situation is also aggravated with much relaxation of work coordination on regulation of trans-boundary river flows and control of their water quality as a result of the USSR collapse and isolation of separate republics. The absence of objective information on water condition of rivers and their contamination sources creates a danger of high ecological risk and psychological stress for inhabitants, localities of that related to the basins of these rivers, and serves as reasoning for claims (occasionally unreasonable) to neighboring countries. Following rivers are the largest trans-boundary ones in Kazakhstan: Ile, Syrdarya, Ural and Irtysh. All these rivers are of great importance for people's life-support of the republic. At the same time presence of a number of large industrial centers, agricultural enterprises and radiation-dangerous objects in the basins of these rivers creates a potential danger of chemical and radiation contamination for their water flows. Objective information on its influence rate is required. The most acceptable form of the control of radiation and hydro-chemical situation in the basins of transboundary rivers is their monitoring based on modern nuclear-and-physical methods of analysis. Very important factor in organization of such monitoring system is participation of all the countries concerned with the basin of the river under the control. There is a work experience of many years in Central Asia on monitoring of large Syrdarya and Amudarya rivers. These works have been carried out since 2000 with the framework of the International project NAVRUZ. Participants of this project are organizations of nuclear profile from Uzbekistan, Kirghizia, Tajikistan and Kazakhstan. The collaborator of this project is the Sandia National Laboratories (SNL), USA. Experience of these

Traditional definitions of risk partition concern into the probability of occurrence and the consequence of the event. Most safety analyses focus on probabilistic assessment of an occurrence and the amount of some measurable result of the event, but the real meaning of the ``consequence`` partition is usually afforded less attention. In particular, acceptable social consequence (consequence accepted by the public) frequently differs significantly from the metrics commonly proposed by risk analysts. This paper addresses some of the important system development issues associated with consequences, focusing on ``high consequence operations safety.``

Transboundary Clusters in the Coastal Zones of the European Part of Russia: Inventory, Typology, Factors, and Prospects

Directory of Open Access Journals (Sweden)

Druzhinin A. G.

2017-12-01

Full Text Available This article presents an inventory and a typology of the existing and emerging economic clusters in the coastal zone of the European part of Russia. The authors hold that transboundary clustering takes priority in the Baltic coastal region — nine of the 56 clusters identified are located in the Kaliningrad region and another eight in Saint Petersburg and the Leningrad region. The authors describe major catalysts and immanent inhibitors in coastal zones. The former include a high density of coastal economies, proximity to international markets, and better logistics and communications. The inhibitors comprise geopolitical risks and institutional barriers. It is shown that the potential and prospects of transboundary clustering are affected by both global integration and disintegration patterns, coastal infrastructure, geopolitical and geoeconomic ‘neighbourhood’, cultural excellence, and business and investment environment.

The paper reports on the study of radionuclide and elemental composition of water, bottom sediment and soil samples collected at the border areas of the following transboundary rivers in Kazakhstan: Chagan, Ural, Ilek, Tobol, Ayat, Irtysh, Emel, Ili, Tekes, Shu, Karabalta, Talas and Syrdarya. The employed analyses include the following methods: instrumental gamma-ray spectrometry, radiochemical analysis, neutron activation analysis, XRF and the inductively coupled plasma mass spectrometry (ICP-MS). Evidence of water environment contamination with radionuclides and toxic elements has been revealed in many of the studied rivers both in Kazakhstan and in adjacent countries. Transboundary transfer of the contaminants is most likely related to local industry (uranium mining and processing) and the presence of radioactive substances in the river basins. © The Author 2015.

Assessment of transboundary environmental effects in the Pearl River Delta Region: Is there a role for strategic environmental assessment?

International Nuclear Information System (INIS)

Marsden, Simon

2011-01-01

China's EIA Law does not require transboundary proposals to be assessed, despite recognition of this globally, for example in the Espoo Convention and Kiev Protocol, and in the European EIA and SEA Directives. In a transboundary context assessment within a state is unusual, as regulating these effects is primarily about the relationship between states. However where a state has more than one legal system such as in the Pearl River Delta (PRD) Region of southern China, transboundary effects should also be addressed. Yet despite the geographical connections between Guangdong Province in mainland China (where the EIA Law applies) and the Hong Kong and Macau Special Administrative Regions (which have their own provisions, neither of which requires transboundary assessments), EIA and SEA are carried out separately. Coordinated or joint approaches to transboundary assessment are generally absent, with the legal autonomy of Hong Kong and Macau a major constraint. As a result institutional responses at the policy level have developed. The article considers global experiences with regulating transboundary EIA and SEA, and analyses potential application to land use, transport and air and water planning in the PRD Region. If applied, benefits may include prevention or mitigation of cumulative effects, broader public participation, and improvements to environmental governance. The PRD Region experience may encourage China to conduct and coordinate EIA and SEA processes with neighbouring states, which has been non-existent or extremely limited to date.

Climate change will have an impact on water cycles, with increased river flows in some areas, and decreased river flows in others. This report focuses on climate change related issues of water management in boundary and transboundary areas between Canada and the United States. Water resources in these areas are governed by agreements between provinces, territories and the federal governments of Canada and the United States. The Climate Change Action Fund and Natural Resources Canada launched a project through a partnership between the Global Change Strategies International (GCSI), the Institute for Catastrophic Loss Reduction (ICLR) and the Meteorological Services of Canada (MSC). The objective was to address potential difficulties in water management resources within North America. This report presents the results of the collaboration. It includes climate scenarios and climate model outputs on future temperature and precipitation by 2050, under a range of emission scenarios. It also includes an analysis of Canada-United States transboundary water instruments for vulnerability to climate change, as well as perceptions of fairness in allocating water in the Saskatchewan River Basin. This report also includes a review of the terms of existing Treaties and Agreements of 11 river basins between Canada and the United States on boundary and transboundary waters. The report concludes that it is very likely that much of Canada will see increased intense precipitation events while the interior regions will have increased risk of drought. These two projections will have major implications for river flows and the management of water resource. Seven recommendations were presented to ensure that water is allocated fairly and responsibly. refs., tabs., figs.

The Nooksack-Abbotsford-Sumas (NAS) Transboundary Watershed, which spans a portion of the western interface of British Columbia, Washington State, as well as the Lummi Nation and the Nooksack Tribal lands, supports agriculture, estuarine fisheries, diverse wildlife, and urban areas. Excess N has contributed to surface and ground water pollution, shellfish closure, and impaired air quality (such as haze or smog) in some areas in the watershed. The goal of this project is to determine the distribution and quantities of N fluxes of the watershed using site-specific and high-resolution data on N that originates from energy use, transportation, fertilization, wastewater treatment plants (WWTP), animal feeding and manure production, crops and more. This project is one of seven international demonstration projects contributing knowledge of regional N budgets and collaborative approaches toward N management as part of the International Nitrogen Management System (INMS). Successful N reduction relies on the partnership of all stakeholders with appropriate institutions to integrate science, outreach and management efforts. This project will bring together stakeholders on both sides of the international border for a first comprehensive, quantitative characterization of all N inventories and fluxes across this international watershed. Using crop-specific fertilizer application rates and wind-shield-survey land use data, we estimated that the annual fertilizer N input to the U.S. portion of the watershed was about 3779 metric tons (MT), which is very close to the USGS estimate of 3955 MT. Based on county level animal census data, we estimated total excretion N from major livestock (cattle) to be 7895 MT on the U.S. side. Using existing model results from other studies, we estimated that the annual N loading on the U.S. side was about 351 MT from point sources, 527 MT from atmospheric deposition, and about 7 MT from alder fixation. The preliminary results demonstrate an

Consequence Prioritization Process for Potential High Consequence Events (HCE)

This document describes the process for Consequence Prioritization, the first phase of the Consequence-Driven Cyber-Informed Engineering (CCE) framework. The primary goal of Consequence Prioritization is to identify potential disruptive events that would significantly inhibit an organization’s ability to provide the critical services and functions deemed fundamental to their business mission. These disruptive events, defined as High Consequence Events (HCE), include both events that have occurred or could be realized through an attack of critical infrastructure owner assets. While other efforts have been initiated to identify and mitigate disruptive events at the national security level, such as Presidential Policy Directive 41 (PPD-41), this process is intended to be used by individual organizations to evaluate events that fall below the threshold for a national security. Described another way, Consequence Prioritization considers threats greater than those addressable by standard cyber-hygiene and includes the consideration of events that go beyond a traditional continuity of operations (COOP) perspective. Finally, Consequence Prioritization is most successful when organizations adopt a multi-disciplinary approach, engaging both cyber security and engineering expertise, as in-depth engineering perspectives are required to recognize and characterize and mitigate HCEs. Figure 1 provides a high-level overview of the prioritization process.

Five-year interim report of the United States-Mexico Transboundary Aquifer Assessment Program: 2007--2012

Science.gov (United States)

Alley, William M.

2013-01-01

Transboundary aquifers are an essential, and in many cases, singular source of water for United States – Mexico border communities, particularly in arid regions. Declining water levels, deteriorating water quality, and increasing use of groundwater resources by municipal, industrial, and agricultural water users on both sides of the international border have raised concerns about the long-term availability of this supply. Water quantity and quality are determining and limiting factors that ultimately control agriculture, future economic development, population growth, human health, and ecological conditions along the border. Knowledge about the extent, depletion rates, and quality of transboundary aquifers, however, is limited and, in some areas, completely absent. The U.S. – Mexico Transboundary Aquifer Assessment Act (Public Law 109-448), referred to in this report as “the Act,” was signed into law by the President of the United States on December 22, 2006, to conduct binational scientific research to systematically assess priority transboundary aquifers and to address water information needs of border communities. The Act authorizes the Secretary of the Interior, through the U.S. Geological Survey (USGS), to collaborate with the States of Arizona, New Mexico, and Texas through their Water Resources Research Institutes (WRRIs) and with the International Boundary and Water Commission (IBWC), stakeholders, and Mexican counterparts to provide new information and a scientific foundation for State and local officials to address pressing water-resource challenges along the U.S. – Mexico border.

Currently important animal disease management issues in sub-Saharan Africa : policy and trade issues

Directory of Open Access Journals (Sweden)

G.R. Thomson

2009-09-01

Full Text Available The present international approach to management of transboundary animal diseases (TADs is based on the assumption that most can be eradicated ; consequently, that is the usual objective adopted by international organizations concerned with animal health. However, for sub-Saharan Africa and southern Africa more particularly, eradication of most TADs is impossible for the foreseeable future for a variety of technical, financial and logistical reasons. Compounding this, the present basis for access to international markets for products derived from animals requires that the area of origin (country or zone is free from trade-influencing TADs. The ongoing development of transfrontier conservation areas (TFCAs, extending across huge areas of southern Africa, therefore presents a development conundrum because it makes creation of geographic areas free from TADs more difficult and brings development based on wildlife conservation on the one hand and that based on livestock production on the other into sharp conflict. Sub-Saharan Africa is consequently confronted by a complex problem that contributes significantly to retarded rural development which, in turn, impedes poverty alleviation. In southern Africa specifically, foot-and-mouth disease (FMD presents the greatest problem in relation to access to international markets for animal products. However, it is argued that this problem could be overcome by a combination between (1 implementation of a commodity-based approach to trade in products derived from animals and (2 amendment of the international standards for FMD specifically (i.e. the FMD chapter in the Terrestrial Animal Health Code of the World Organisation for Animal Health [OIE] so that occurrence of SAT serotype viruses in free-living African buffalo need not necessarily mean exclusion of areas where buffalo occur from international markets for animal products. This would overcome a presently intractable constraint to market access for

2008-05-01

The objective of the inventory phase 1 of the project on the title subject is two-fold: (1) to assess the impacts of different CO2 capture technologies on transboundary air pollution in the Netherlands in 2020. Other possible environmental impacts such as toxic emissions and safety are considered qualitatively; and (2) to provide recommendations for further research in the in-depth phase 2 in order to address the current knowledge gaps found in this area. The inventory summarises all (public) available information that is relevant for transboundary air pollution and presents it in understandable terms for environmental experts and policymakers who are not CCS (carbon dioxide capture and storage) experts. The project surveys the present scientific literature and interviews key players in the carbon capture community in the Netherlands to present the current insights and state of capture technology, particularly with respect to transboundary air pollution. This has been done taking into account the angles of both research and policy needs. The information gathered is combined with scenario information for the year 2020 on carbon capture technology and transboundary air pollution in order to sketch ranges of possible impacts of carbon capture technologies in the Netherlands in this year. Chapter 2 explains the methodology and the research process taken in the project. Chapter 3 introduces the different capture technologies in the form a structured description. Chapter 4 describes the results of the assessment of capture technologies in terms of a comparative analysis and a what-if emission scenario analysis for the Netherlands. Chapter 5 closes the report with conclusions and recommendations for further research

The transboundary nature of water resources demands a transboundary approach to their monitoring and management. However, transboundary water projects raise a challenging set of problems related to communication issues, and standardization of sampling, analysis and data management methods. This manual addresses those challenges and provides the information and guidance needed to perform the Navruz Project, a cooperative, transboundary, river monitoring project involving rivers and institutions in Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan facilitated by Sandia National Laboratories in the U.S. The Navruz Project focuses on waterborne radionuclides and metals because of their importance to public health and nuclear materials proliferation concerns in the region. This manual provides guidelines for participants on sample and data collection, field equipment operations and procedures, sample handling, laboratory analysis, and data management. Also included are descriptions of rivers, sampling sites and parameters on which data are collected. Data obtained in this project are shared among all participating countries and the public through an internet web site, and are available for use in further studies and in regional transboundary water resource management efforts. Overall, the project addresses three main goals: to help increase capabilities in Central Asian nations for sustainable water resources management; to provide a scientific basis for supporting nuclear transparency and non-proliferation in the region; and to help reduce the threat of conflict in Central Asia over water resources, proliferation concerns, or other factors.

The current study was conducted to shed light on the role of imported camels as a transboundary vector for emerging exotic Salmonella serovars. Fecal samples were collected from 206 camels directly after slaughtering including 25 local camels and 181 imported ones as well as stool specimens were obtained from 50 slaughterhouse workers at the same abattoir. The obtained samples were cultured while Salmonella serovars were identified through Gram's stain films, biochemical tests and serotyping with antisera kit. Moreover, the obtained Salmonella serovars were examined by PCR for the presence of invA and stn genes. The overall prevalence of Salmonella serovars among the examined camels was 8.3%. Stn gene was detected in the vast majority of exotic strains (11/14) 78.6% including emerging serovars such as Salmonella Saintpaul, S. Chester, S. Typhimurium whereas only one isolate from local camels carried stn gene (1/3) 33.3%. On the other hand, none of the examined humans yielded positive result. Our findings highlight the potential role of imported camels as a transboundary vector for exotic emerging Salomenella serovars.

Monsoon circulation is an important process that affects long-range transboundary transport of anthropogenic contaminants such as mercury (Hg). During the Indian monsoon season of 2013, a total of 92 and 26 atmospheric water vapor samples were collected at Lhasa, the largest city of the Tibet, for Hg and major ions analysis, respectively. The relatively low pH/high electronic conductivity values, together with the fact that NH{sub 4}{sup +} in atmospheric water vapor was even higher than that determined in precipitation of Lhasa, indicated the effects of anthropogenic perturbations through long-range transboundary atmospheric transport. Concentrations of Hg in atmospheric water vapor ranged from 2.5 to 73.7 ng L{sup −1}, with an average of 12.5 ng L{sup −1}. The elevated Hg and major ions concentrations, and electronic conductivity values were generally associated with weak acidic samples, and Hg mainly loaded with anthropogenic ions such as NH{sub 4}{sup +}. The results of principal component analysis and trajectory analysis suggested that anthropogenic emissions from the Indian subcontinent may have largely contributed to the determined Hg in atmospheric water vapor. Furthermore, our study reconfirmed that below-cloud scavenging contribution was significant for precipitation Hg in Lhasa, and evaluated that on average 74.1% of the Hg in precipitation could be accounted for by below-cloud scavenging. - Highlights: • The low pH/high electronic conductivity was found in atmospheric water vapor. • Anthropogenic NH{sub 4}{sup +} was higher than that determined in precipitation of Lhasa. • Elevated Hg and major ions levels were usually associated with weak acidic samples. • Hg in atmospheric water vapor was largely influenced by transboundary transport. • Below-cloud scavenging accounted for most Hg in precipitation.

International trade standards for commodities and products derived from animals: the need for a system that integrates food safety and animal disease risk management.

A case is made for greater emphasis to be placed on value chain management as an alternative to geographically based disease risk mitigation for trade in commodities and products derived from animals. The geographic approach is dependent upon achievement of freedom in countries or zones from infectious agents that cause so-called transboundary animal diseases, while value chain-based risk management depends upon mitigation of animal disease hazards potentially associated with specific commodities or products irrespective of the locality of production. This commodity-specific approach is founded on the same principles upon which international food safety standards are based, viz. hazard analysis critical control points (HACCP). Broader acceptance of a value chain approach enables animal disease risk management to be combined with food safety management by the integration of commodity-based trade and HACCP methodologies and thereby facilitates 'farm to fork' quality assurance. The latter is increasingly recognized as indispensable to food safety assurance and is therefore a pre-condition to safe trade. The biological principles upon which HACCP and commodity-based trade are based are essentially identical, potentially simplifying sanitary control in contrast to current separate international sanitary standards for food safety and animal disease risks that are difficult to reconcile. A value chain approach would not only enable more effective integration of food safety and animal disease risk management of foodstuffs derived from animals but would also ameliorate adverse environmental and associated socio-economic consequences of current sanitary standards based on the geographic distribution of animal infections. This is especially the case where vast veterinary cordon fencing systems are relied upon to separate livestock and wildlife as is the case in much of southern Africa. A value chain approach would thus be particularly beneficial to under-developed regions of

Paradigm for Distributive & Procedural Justice in Equitable Apportionment of Transboundary Ganges Waters Under Changing Climate & Landuse

Science.gov (United States)

Tyagi, H.; Gosain, A. K.; Khosa, R.; Anand, J.

2015-12-01

Rivers have no regard for human demarcated boundaries. Besides, ever increasing demand-supply gap & vested riparian interests, fuel transboundary water conflicts. For resolving such disputes, appropriation doctrines advocating equity & fairness have received endorsement in the Helsinki Rules-1966 & UN Convention-1997. Thus, current study proposes the principle of equitable apportionment for sharing Ganges waters as it balances the interests & deservedness of all stakeholders, namely, India & its 11 states, Bangladesh, Nepal, & China. The study endeavors to derive a reasonable share of each co-basin state by operationalizing the vague concepts of fairness & equity through an objective & quantitative framework encompassing proportionality & egalitarianism for distributive & procedural justice. Equal weightage factors reflecting hydrology, geography & water use potential are chosen for fair share computation, wherein each contender ranks these factors to maximize his entitlement. If cumulative claims exceed the water availability, each claimant puts forth next ranked factor & this process continues till the claims match availability. Due to inter-annual variability in few factors, scenarios for Rabi & Kharif seasons are considered apart from cases for maximum, upper quartile, median, lower quartile & minimum. Possibility of spatial homogeneity & heterogeneity in factors is also recognized. Sometimes lack of technical information hinders transboundary dispute resolution via legal mechanisms. Hence, the study also attempts to bridge this gap between law & technology through GIS-based SWAT hydrologic model by estimating the Ganges water yield, & consequent share of each riparian for range of flows incorporating e-flows as well, under present & future climate & landuse scenarios. 82% of India's territory lies within interstate rivers, & therefore this research is very pertinent as it can facilitate the decision makers in effective interstate water conflict resolution.

The article reviewed the law on water in local and transboundary contexts.The aim was to highlight the mechanisms for facilitating equity in the allocation and sharing of the resource. It has been demonstrated that, the relevant local and transboundary laws are in need for further urgent development in order to be able to achieve their objectives. The objective that will be of greatest importance in the 21. century is that of ensuring that, water conservation is fostered and promoted. The effort to meet the increasing demand for water, on the whole, have focused on attempts to increase supply to water users. In the era of increasing water scarcity, the management of demand and development of legal and other mechanisms to ensure efficient utilisation of the available water resources will become the central issue of the day. Equity in allocation will take, as it's central premises the conservation of the limited resource. The law will therefore need to develop increasingly in the direction of fostering a conservation ethic

The percentage contribution of trans-boundary mercury (Hg) from China at different locations in South Korea was estimated from Hg anthropogenic emission distributions using the Hg dispersion model, CMAQ-Hg. This investigation quantifies the trans-boundary Hg emissions as contribution ratios. In addition, the long-range transportation frequency is also calculated, to verify inflow cases from China. The seasonal distribution of the Hg contribution ratio was found to be highest in winter (40%), followed by fall (16%). Seasonal observations of Hg inflow frequencies were estimated as 40%, 25%, 21%, and 4% in winter, fall, summer, and spring, respectively, at the same location. Such results would be produced by the wind generally blowing from the west and north-west with a speed of 5.0 m/s and 4.5 m/s, respectively, during winter and fall, around the study area. This study made an effort to quantify the trans-boundary Hg transport and to plot Hg anthropogenic emissions distribution in the region.

Since 2013, hundreds of thousands of refugees have migrated southward to Jordan to escape the Syrian civil war that began in mid-2011. Evaluating impacts of conflict and migration on land use and transboundary water resources in an active war zone remains a challenge. However, spatial and statistical analyses of satellite imagery for the recent period of Syrian refugee mass migration provide evidence of rapid changes in land use, water use, and water management in the Yarmouk-Jordan river watershed shared by Syria, Jordan, and Israel. Conflict and consequent migration caused ∼50% decreases in both irrigated agriculture in Syria and retention of winter rainfall in Syrian dams, which gave rise to unexpected additional stream flow to downstream Jordan during the refugee migration period. Comparing premigration and postmigration periods, Syrian abandonment of irrigated agriculture accounts for half of the stream flow increase, with the other half attributable to recovery from a severe drought. Despite this increase, the Yarmouk River flow into Jordan is still substantially below the volume that was expected by Jordan under the 1953, 1987, and 2001 bilateral agreements with Syria.

The transboundary nature of seabird ecology: Chapter 8

Science.gov (United States)

Jodice, Patrick G.R.; Suryan, Robert M.

2015-01-01

The term ‘seabird’ is generally applied to avian species that forage in the marine environment over open water. Seabirds typically nest in colonies and are long-lived species with low annual reproductive rates. Seabird breeding sites typically occur on islands or along coasts and as such are often at the boundaries of ecological or political zones. During the breeding season, seabirds cross a very distinct terrestrial/marine ecological boundary on a regular basis to forage. Even relatively ‘local’ species cross multiple jurisdictions within a day (e.g., state lands and waters, and federal waters) while pelagic species may transit through international waters on a daily, weekly, or monthly time-frame. Seabird life-histories expose individuals and populations to environmental conditions affecting both terrestrial and marine habitats. The wide-ranging and transboundary nature of seabird ecology also exposes these species to various environmental and anthropogenic forces such as contamination, commercial fisheries and climate forcing that also are transboundary in nature. Therefore, wherever conservation of seabirds or the management of their populations is the goal, consideration must be given to ecosystem dynamics on land and at sea. Because the jurisdiction of agencies does not cross the land-sea boundary in the same manner as the seabirds they are managing, these efforts are facilitated by multi-agency communication and collaboration. By their very nature and by the nature of the systems that they must function within, seabirds embody the complexity of wildlife ecology and conservation in the twenty-first century.

A significant fraction of world population is projected to experience increased water stress in response　to the combined effects of population growth and climate change. Some previous studies have suggested that high water stress had significant causality for civil war, and militarized conflict and trans-boundary water conflict in international river basin. On the other hand, some previous empirical analyses have found that institutionalization (e.g., specific provisions in trans-boundary freshwater treaties) in international river basin was associated with a lower risk of water conflicts during water scarcity. The purpose of this study is to identify these water conflict "hotspots", integrating institutional and governance mechanisms of adaptations to impact of water stress. These adaptations is classified to 4 abilities and skills and then used to calculate the adaptive capacity. The adaptive capacity includes the way to manage water conflict effectively, plan to deal with　uncertainty in the future, alter current situation and create institutionalization with common perspective throughout the whole activities. This study identifies water conflict "hotspots" by combining high water stress areas projected by a global water resource model and a lower degree of the adaptive capacity. This study finds that 9 water conflict "hotspots" in Africa, Asia and South America.

Recent experiments on flapping flight in animals have shown that a variety of unrelated species shed a wake behind left and right wings consisting of both tip and root vortices. Here we present an investigation using Particle Image Velocimetry (PIV) of the behaviour and interaction of trailing vortices shed by paired, fixed wings that simplify and mimic the wake of a flying animal with a non-lifting body. We measured flow velocities at five positions downstream of two adjacent NACA 0012 aerofoils and systematically varied aspect ratio, the gap between the wings (corresponding to the width of a non-lifting body), angle of attack, and the Reynolds number. The range of aspect ratios and Reynolds number where chosen to be relevant to natural fliers and swimmers, and insect flight in particular. We show that the wake behind the paired wings deformed as a consequence of the induced flow distribution such that the wingtip vortices convected downwards while the root vortices twist around each other. Vortex interaction and wake deformation became more pronounced further downstream of the wing, so the positioning of PIV measurement planes in experiments on flying animals has an important effect on subsequent force estimates due to rotating induced flow vectors. Wake deformation was most severe behind wings with lower aspect ratios and when the distance between the wings was small, suggesting that animals that match this description constitute high-risk groups in terms of measurement error. Our results, therefore, have significant implications for experimental design where wake measurements are used to estimate forces generated in animal flight. In particular, the downstream distance of the measurement plane should be minimised, notwithstanding the animal welfare constraints when measuring the wake behind flying animals.

Objective. Before peripheral nerve electrodes can be used for the restoration of sensory and motor functions in patients with neurological disorders, the behavioral and histological consequences of these devices must be investigated. These indices of biocompatibility can be defined in terms of desired functional outcomes; for example, a device may be considered for use as a therapeutic intervention if the implanted subject retains functional neurons post-implantation even in the presence of a foreign body response. The consequences of an indwelling device may remain localized to cellular responses at the device-tissue interface, such as fibrotic encapsulation of the device, or they may affect the animal more globally, such as impacting behavioral or sensorimotor functions. The objective of this study was to investigate the overall consequences of implantation of high-electrode count intrafascicular peripheral nerve arrays, High Density Utah Slanted Electrode Arrays (HD-USEAs; 25 electrodes mm-2). Approach. HD-USEAs were implanted in rat sciatic nerves for one and two month periods. We monitored wheel running, noxious sensory paw withdrawal reflexes, footprints, nerve morphology and macrophage presence at the tissue-device interface. In addition, we used a novel approach to contain the arrays in actively behaving animals that consisted of an organic nerve wrap. A total of 500 electrodes were implanted across all ten animals. Main results. The results demonstrated that chronic implantation (⩽8 weeks) of HD-USEAs into peripheral nerves can evoke behavioral deficits that recover over time. Morphology of the nerve distal to the implantation site showed variable signs of nerve fiber degeneration and regeneration. Cytology adjacent to the device-tissue interface also showed a variable response, with some electrodes having many macrophages surrounding the electrodes, while other electrodes had few or no macrophages present. This variability was also seen along the length

Globally 286 river basins extend across international borders, covering over 61.9 million km2 of the earth's surface and hosting a total of approximately 2.7 billion people. In these basins, transboundary water resources support an interdependent web of environmental, political, and economic systems that can enhance or destabilize a region. We present an integrated global-scale assessment of transboundary watersheds to identify regions more likely to experience hydro-political tensions over the next decade and beyond based upon environmental, political, and economic indicators. We combine NASA's Gravity Recovery and Climate Experiment (GRACE) measurements of changes in terrestrial water storage with metrics of projected climate change impacts on water variability, the institutional capacity of countries to manage shared water resources, the development of new water infrastructure, per capita gross national income, domestic and international armed conflicts, and recent history of disputes over transboundary waters. The construction of new water-related infrastructure is on-going or planned in many basins worldwide. New water infrastructure is foreseen also in areas where instruments of international cooperation are still absent or limited in scope, e.g. in Southeast Asia, South Asia, Central America, the northern part of the South American continent, and the southern Balkans as well as in different parts of Africa. Moreover, in Central and Eastern Africa, the Middle East, and Central, South and South-East Asia there is a concomitance of several political, environmental and socioeconomic factors that could exacerbate hydropolitical tensions. Our analysis integrates political, economic and environmental metrics and is part of the United Nation's Transboundary Waters Assessment Programme to provide the first global-scale assessment of its type.

Analysis of key thresholds leading to upstream dependencies in global transboundary water bodies

Transboundary water bodies supply 60% of global fresh water flow and are home to about 1/3 of the world's population; creating hydrological, social and economic interdependencies between countries. Trade-offs between water users are delimited by certain thresholds, that, when crossed, result in changes in system behavior, often related to undesirable impacts. A wide variety of thresholds are potentially related to water availability and scarcity. Scarcity can occur because of the country's own water use, and that is potentially intensified by upstream water use. In general, increased water scarcity escalates the reliance on shared water resources, which increases interdependencies between riparian states. In this paper the upstream dependencies of global transboundary river basins are examined at the scale of sub-basin areas. We aim to assess how upstream water withdrawals cause changes in the scarcity categories, such that crossing thresholds is interpreted in terms of downstream dependency on upstream water availability. The thresholds are defined for different types of water availability on which a sub-basin relies: - reliable local runoff (available even in a dry year), - less reliable local water (available in the wet year), - reliable dry year inflows from possible upstream area, and - less reliable wet year inflows from upstream. Possible upstream withdrawals reduce available water downstream, influencing the latter two water availabilities. Upstream dependencies have then been categorized by comparing a sub-basin's scarcity category across different water availability types. When population (or water consumption) grows, the sub-basin satisfies its needs using less reliable water. Thus, the factors affecting the type of water availability being used are different not only for each type of dependency category, but also possibly for every sub- basin. Our results show that, in the case of stress (impacts from high use of water), in 104 (12%) sub- basins out of

A market-based approach to share water and benefits in transboundary river basins

Science.gov (United States)

Arjoon, Diane; Tilmant, Amaury; Herrmann, Markus

2016-04-01

The equitable sharing of benefits in transboundary river basins is necessary to reach a consensus on basin-wide development and management activities. Benefit sharing arrangements must be collaboratively developed to be perceived as efficient, as well as equitable, in order to be considered acceptable to all riparian countries. The current literature falls short of providing practical, institutional arrangements that ensure maximum economic welfare as well as collaboratively developed methods for encouraging the equitable sharing of benefits. In this study we define an institutional arrangement that distributes welfare in a river basin by maximizing the economic benefits of water use and then sharing these benefits in an equitable manner using a method developed through stakeholder involvement. In this methodology (i) a hydro-economic model is used to efficiently allocate scarce water resources to water users in a transboundary basin, (ii) water users are obliged to pay for water, and (iii) the total of these water charges are equitably redistributed as monetary compensation to users. The amount of monetary compensation, for each water user, is determined through the application of a sharing method developed by stakeholder input, based on a stakeholder vision of fairness, using an axiomatic approach. The whole system is overseen by a river basin authority. The methodology is applied to the Eastern Nile River basin as a case study. The technique ensures economic efficiency and may lead to more equitable solutions in the sharing of benefits in transboundary river basins because the definition of the sharing rule is not in question, as would be the case if existing methods, such as game theory, were applied, with their inherent definitions of fairness.

Transboundary Extraction of Groundwater in the Presence of Hydraulic Fracturing

OpenAIRE

Poudel, Biswo N.; Paudel, Krishna P.; Zilberman, David

2013-01-01

We studied transboundary ground water management problems in the presence of hydraulic fracturing (fracking). We found that the presence of risk suggests a need to exercise caution in fracking. We also found that a cooperative outcome implies the decrease in fracking and the increase in steady state survival rate of groundwater. However, water extraction rates remained the same in both cooperative and noncooperative solutions. We also argue that a Pigouvian type tax could be imposed on the na...

Climate and transboundary water management issues

International Nuclear Information System (INIS)

Bjonback, D.

1991-01-01

The potential effects of climate change on transboundary river systems, major water uses, interjurisdictional arrangements, and water issues affecting water management in the Great Plains of Canada are discussed. Three atmospheric general circulation models (GCM) have been applied for a two times carbon dioxide concentration scenario for the Saskatchewan River system. The models were the Goddard Institute for Space Studies (GISS) model, the Geophysical Fluid Dynamics Laboratory (GFDL) model, and the Oregon State University (OSU) model. For all models, soil moisture on the plains was reduced. The GISS model predicted slightly higher runoff for plains-originating streams, and a substantial increase in runoff (32%) in the Rockies. The GFDL model predicted lower runoffs in the plains and Rockies, with some locations near the Alberta-Saskatchewan border indicating zero runoff. The OSU model results generally bracketed the GISS and GFDL results, with total runoff approximating 1951-1980 mean. The GISS model indicated an increase in net basin supply of 28%, while the GFDL model, due to lower runoff and high soil moisture defecits, showed a decrease of 38%. For policy making, monitoring, and research, the GFDL model results can provide important guidelines. Greater attention to demand management and conservation will have short-term benefits in stretching the limited water resource base to support a larger economy, while providing flexibility to cope with future climate as it evolves. 1 ref

Since 2013, hundreds of thousands of refugees have migrated southward to Jordan to escape the Syrian civil war that began in mid-2011. Evaluating impacts of conflict and migration on land use and transboundary water resources in an active war zone remains a challenge. However, spatial and statistical analyses of satellite imagery for the recent period of Syrian refugee mass migration provide evidence of rapid changes in land use, water use, and water management in the Yarmouk–Jordan river watershed shared by Syria, Jordan, and Israel. Conflict and consequent migration caused ∼50% decreases in both irrigated agriculture in Syria and retention of winter rainfall in Syrian dams, which gave rise to unexpected additional stream flow to downstream Jordan during the refugee migration period. Comparing premigration and postmigration periods, Syrian abandonment of irrigated agriculture accounts for half of the stream flow increase, with the other half attributable to recovery from a severe drought. Despite this increase, the Yarmouk River flow into Jordan is still substantially below the volume that was expected by Jordan under the 1953, 1987, and 2001 bilateral agreements with Syria.

The Cooperative Programme for the Monitoring and Evaluation of the Long Range Transmission and Air Pollutants in Europe, EMEP, plays an integral part in data collection and scientific cooperation for implementation of the 1979 Geneva Convention on Long Range Transboundary Air Pollution. Within EMEP, the Meteorological Synthesizing Centre - West (MSC-W) is an international technical centre. The purpose of the MSC-W, focusing in part on acidifying substances, is to estimate the concentrations of relevant sulphur and nitrogen pollutants across Europe on the basis of emission information and meteorological data, and to estimate the transboundary fluxes of these substances. Responding to these specific obligations, the report presents calculations of sulphur and nitrogen concentrations and depositions and of their transboundary fluxes. The calculations are performed by the receptor oriented one layer trajectory (Lagrangian) acid deposition model, which during 1995 has been used to estimate acidifying pollutant fluxes for the ten year period 1985-1994. This corresponds to the period between initial signing and conclusion of the first Sulphur Protocol, signed in Helsinki in 1985. 90 refs., 42 figs., 43 tabs.

2006-01-01

This article presents a brief overview of the development of high-resolution SPECT for small-animal imaging. A pinhole collimator has been used for high-resolution animal SPECT to provide better spatial resolution and detection efficiency in comparison with a parallel-hole collimator. The theory of imaging characteristics of the pinhole collimator is presented and the designs of the pinhole aperture are discussed. The detector technologies used for the development of small-animal SPECT and the recent advances are presented. The evolving trend of small-animal SPECT is toward a multi-pinhole and a multi-detector system to obtain a high resolution and also a high detection efficiency. (authors)

The Convergence of High-Consequence Livestock and Human Pathogen Research and Development: A Paradox of Zoonotic Disease

Julia M. Michelotti

2018-05-01

Full Text Available The World Health Organization (WHO estimates that zoonotic diseases transmitted from animals to humans account for 75 percent of new and emerging infectious diseases. Globally, high-consequence pathogens that impact livestock and have the potential for human transmission create research paradoxes and operational challenges for the high-containment laboratories that conduct work with them. These specialized facilities are required for conducting all phases of research on high-consequence pathogens (basic, applied, and translational with an emphasis on both the generation of fundamental knowledge and product development. To achieve this research mission, a highly-trained workforce is required and flexible operational methods are needed. In addition, working with certain pathogens requires compliance with regulations such as the Centers for Disease Control (CDC and the U.S. Department of Agriculture (USDA Select Agent regulations, which adds to the operational burden. The vast experience from the existing studies at Plum Island Animal Disease Center, other U.S. laboratories, and those in Europe and Australia with biosafety level 4 (BSL-4 facilities designed for large animals, clearly demonstrates the valuable contribution this capability brings to the efforts to detect, prepare, prevent and respond to livestock and potential zoonotic threats. To raise awareness of these challenges, which include biosafety and biosecurity issues, we held a workshop at the 2018 American Society for Microbiology (ASM Biothreats conference to further discuss the topic with invited experts and audience participants. The workshop covered the subjects of research funding and metrics, economic sustainment of drug and vaccine development pipelines, workforce turnover, and the challenges of maintaining operational readiness of high containment laboratories.

Animals In Synchrotrons: Overcoming Challenges For High-Resolution, Live, Small-Animal Imaging

Donnelley, Martin; Parsons, David; Morgan, Kaye; Siu, Karen

2010-01-01

Physiological studies in small animals can be complicated, but the complexity is increased dramatically when performing live-animal synchrotron X-ray imaging studies. Our group has extensive experience in high-resolution live-animal imaging at the Japanese SPring-8 synchrotron, primarily examining airways in two-dimensions. These experiments normally image an area of 1.8 mmx1.2 mm at a pixel resolution of 0.45 μm and are performed with live, intact, anaesthetized mice.There are unique challenges in this experimental setting. Importantly, experiments must be performed in an isolated imaging hutch not specifically designed for small-animal imaging. This requires equipment adapted to remotely monitor animals, maintain their anesthesia, and deliver test substances while collecting images. The horizontal synchrotron X-ray beam has a fixed location and orientation that limits experimental flexibility. The extremely high resolution makes locating anatomical regions-of-interest slow and can result in a high radiation dose, and at this level of magnification small animal movements produce motion-artifacts that can render acquired images unusable. Here we describe our experimental techniques and how we have overcome several challenges involved in performing live mouse synchrotron imaging.Experiments have tested different mouse strains, with hairless strains minimizing overlying skin and hair artifacts. Different anesthetics have also be trialed due to the limited choices available at SPring-8. Tracheal-intubation methods have been refined and controlled-ventilation is now possible using a specialized small-animal ventilator. With appropriate animal restraint and respiratory-gating, motion-artifacts have been minimized. The animal orientation (supine vs. head-high) also appears to affect animal physiology, and can alter image quality. Our techniques and image quality at SPring-8 have dramatically improved and in the near future we plan to translate this experience to the

The decrease in the number of animals with cytogenetic anomalies in bone marrow cells in voles, was revealed, that testified to the selection by the radioresistance. The obtained data allow us to make conclusion that the increase of ionizing radiation is a particular case of ecological changes leading to the microevolution events connected with the selection by the stability to new conditions of the reproduction of populations

Black Carbon Measurements From Ireland's Transboundary Network (TXB)

Science.gov (United States)

Spohn, T. K.; Martin, D.; O'Dowd, C. D. D.

2017-12-01

Black Carbon (BC) is carbonaceous aerosol formed by incomplete fossil fuel combustion. Named for its light absorbing properties, it acts to trap heat in the atmosphere, thus behaving like a greenhouse gas, and is considered a strong, short-lived climate forcer by the International Panel on Climate Change (IPCC). Carbonaceous aerosols from biomass burning (BB) such as forest fires and residential wood burning, also known as brown carbon, affect the ultra violet (UV) light absorption in the atmosphere as well. In 2016 a three node black carbon monitoring network was established in Ireland as part of a Transboundary Monitoring Network (TXB). The three sites (Mace Head, Malin Head, and Carnsore Point) are coastal locations on opposing sides of the country, and offer the opportunity to assess typical northern hemispheric background concentrations as well national and European pollution events. The instruments deployed in this network (Magee Scientific AE33) facilitate elimination of the changes in response due to `aerosol loading' effects; and a real-time calculation of the `loading compensation' parameter which offers insights into aerosol optical properties. Additionally, these instruments have an inbuilt algorithm, which estimates the difference in absorption in the ultraviolet wavelengths (mostly by brown carbon) and the near infrared wavelengths (only by black carbon).Presented here are the first results of the BC measurements from the three Irish stations, including instrument validation, seasonal variation as well as local, regional, and transboundary influences based on air mass trajectories as well as concurrent in-situ observations (meteorological parameters, particle number, and aerosol composition). A comparison of the instrumental algorithm to off-line sensitivity calculations will also be made to assess the contribution of biomass burning to BC pollution events.

2010-01-01

Full Text Available This work focuses on hydrographic and hydrological specific of Nišava River. It uses all hydrometric and cartographic information for the Bulgarian part of the catchment. Trans-boundary catchment of Nišava River includes four sub-basins, which are trans-borders too. There are a lot of karst areas in the river basin. The drainage density is 1.09 km/km2. Water resources of Nišava River are 170 million m3. They vary between 300.0 and 84.0 million m3. The period of high water appears in March/April and finishes in June. The frequency of monthly maximum is biggest in April or May. The monthly minimum appears most often in September or October. Floods in the catchment of the river Nišava are most often in March, May and June. Some of the rivers lose its waters in the karst areas and dries up during the summer. The average number of days with ice is between 10 and 70. The chemical and ecological status of river water is good. .

Advances in the Knowledge of Transboundary Aquifers Shared by Canada and the USA, through the UNESCO's IHP ISARM Initiative

Science.gov (United States)

Rivera, A.

2015-12-01

Canada's involvement in the UNESCO IHP ISARM initiative prompted an accrued analysis on the knowledge and state of transboundary aquifers located along the Canada-USA border. As a result, 10 Transboundary Aquifer Systems (TAS) were identified and some have been assessed in cooperation with the United States. This study is a review of the current state of the 10 TAS. Documentation of scientifically-based knowledge on TAS is an important step in identifying potential issues in policies that might be adopted to address shared water-resource issues. The newly acquired hydrological insights for this very long international border emphasizes the need for more scientific data, widespread communication and information sharing between Canadian and American organizations, and a more clearly defined governments' role to manage groundwater at the international level. The study reviews the legal frameworks and summarises the current scientific knowledge for the TAS with respect to the hydrologic and geologic framework as well as some of the major drivers for supply and demand. It also describes the links, approach and relevance of studies on the TAS to the UN Law of Transboundary Aquifers and on how these might fit in the ISARM's regional strategy for the assessment and management of the TAS. Clear communication, shared knowledge and common objectives in the management of TAS will prepare the countries for future negotiations and cooperative binational programs. Encouraged by the ISARM approach of the International Hydrological Programme of UNESCO, Canada is now looking forward to playing a key regional role in improving water management, facilitating transboundary water sharing, and enhancing water research and data sharing in future relations between these two nations.

Relationship between urbanisation and pollutant emissions in transboundary river basins under the strategy of the Belt and Road Initiative.

Science.gov (United States)

Yu, Sen; Lu, Hongwei

2018-07-01

Urbanisation has increased the discharge of pollutants, altered water flow regimes, and modified the morphology of transboundary river basins. All these actions have resulted in multiple pressures on aquatic ecosystems of transboundary river basins, undermining the healthy development of their aquatic ecosystems as well as impairing the sustainable economic and social development associated therewith. Quantifying the relationship between socio-economic factors, and water environment systems, and understanding the multiple pressures in their combined impact on environmental fairness of transboundary river basins is challenging, and it is crucial to the strategic planning of the Belt and Road strategy. Here, the Songhua River basin, which is the largest branch of the China-Russia boundary river is taken as the study area. The Environmental Kuznets Curve (EKC) model, which is coupled with the integrated model (pollutant emissions intensity, pollutant discharge efficiency, and pollutant emissions per capita), are used to reveal the spatio-temporal variations in regional pollutant emissions in the SRB. The results show that the features of the EKC are present in the pollutant emissions during economic development of the SRB. It also demonstrates that the turning point value of the EKC appeared when the GDP per capita is around ¥40,000 (CNY) in the SRB, which means that the pollutant emissions show an increasing trend, when the GDP per capita is less than ¥40,000. Our findings could contribute to a better understanding of the coupling relationship between pollutant emissions in transboundary river basins and urbanisation process in water stress to help address water allocation problems.

Daily and hourly chemical impact of springtime transboundary aerosols on Japanese air quality

2013-02-01

Full Text Available The regular eastward drift of transboundary aerosol intrusions from the Asian mainland into the NW Pacific region has a pervasive impact on air quality in Japan, especially during springtime. Analysis of 24-h filter samples with Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES and Mass Spectrometry (ICP-MS, and hourly Streaker with Particle Induced X-ray Emission (PIXE samples collected continuously for six weeks reveal the chemistry of successive waves of natural mineral desert dust ("Kosa" and metalliferous sulphatic pollutants arriving in western Japan during spring 2011. The main aerosol sources recognised by Positive Matrix Factorization (PMF analysis of Streaker data are mineral dust and fresh sea salt (both mostly in the coarser fraction PM_2.5–10, As-bearing sulphatic aerosol (PM_0.1–2.5, metalliferous sodic particulate matter (PM interpreted as aged, industrially contaminated marine aerosol, and ZnCu-bearing aerosols. Whereas mineral dust arrivals are typically highly transient, peaking over a few hours, sulphatic intrusions build up and decline more slowly, and are accompanied by notable rises in ambient concentrations of metallic trace elements such as Pb, As, Zn, Sn and Cd. The magnitude of the loss in regional air quality due to the spread and persistence of pollution from mainland Asia is especially clear when cleansing oceanic air advects westward across Japan, removing the continental influence and reducing concentrations of the undesirable metalliferous pollutants by over 90%. Our new chemical database, especially the Streaker data, demonstrates the rapidly changing complexity of ambient air inhaled during these transboundary events, and implicates Chinese coal combustion as the main source of the anthropogenic aerosol component.

Assuring quality in high-consequence engineering

In high-consequence engineering organizations, such as Sandia, quality assurance may be heavily dependent on staff competency. Competency-dependent quality assurance models are at risk when the environment changes, as it has with increasing attrition rates, budget and schedule cuts, and competing program priorities. Risks in Sandia's competency-dependent culture can be mitigated through changes to hiring, training, and customer engagement approaches to manage people, partners, and products. Sandia's technical quality engineering organization has been able to mitigate corporate-level risks by driving changes that benefit all departments, and in doing so has assured Sandia's commitment to excellence in high-consequence engineering and national service.

Mercury in products - a source of transboundary pollutant transport

Energy Technology Data Exchange (ETDEWEB)

Munthe, J; Kindbom, K [Swedish Environmental Research Inst., Stockholm (Sweden)

1997-12-01

The purpose of this report is to summarize current knowledge on product-related emissions of mercury to air on a European scale, and to estimate the contribution from mercury contained in products, to the total anthropogenic emissions of mercury to air and transboundary transport of mercury in Europe. Products included in this study are batteries, measuring and control instruments, light sources and electrical equipment, all intentionally containing mercury. The main result of this study is that product-related emission of mercury can contribute significantly to total emissions and transboundary transport of mercury in the European region and that measures to limit the use of mercury in products can contribute to an overall decrease of the environmental input of mercury in Europe. It is concluded that: -Mercury contained in products may be emitted to air during consumption, after disposal when incinerated or when volatilized from landfill. Mercury may also be emitted to air during recycling of scrap metal or when accumulated (stored) in society. -The amount of mercury consumed in batteries and in measuring and control instruments had decreased since the late 1980`s. The total use of mercury in light sources and electrical equipment has not changed significantly during the same time period. The contribution to total anthropogenic emissions of mercury to air in Europe in the mid 1990`s is estimated to be: for batteries 4%; for measuring and control instruments 3%; for lighting and electrical equipment 11%. -Mercury in products leads to significant wet deposition input in Scandinavia. The relative amount of the total deposition flux attributable to products is estimated to be 10-14% 26 refs, 4 figs, 10 tabs

Transboundary fisheries science: Meeting the challenges of inland fisheries management in the 21st century

Science.gov (United States)

Midway, Stephen R.; Wagner, Tyler; Zydlewski, Joseph D.; Irwin, Brian J.; Paukert, Craig P.

2016-01-01

Managing inland fisheries in the 21st century presents several obstacles, including the need to view fisheries from multiple spatial and temporal scales, which usually involves populations and resources spanning sociopolitical boundaries. Though collaboration is not new to fisheries science, inland aquatic systems have historically been managed at local scales and present different challenges than in marine or large freshwater systems like the Laurentian Great Lakes. Therefore, we outline a flexible strategy that highlights organization, cooperation, analytics, and implementation as building blocks toward effectively addressing transboundary fisheries issues. Additionally, we discuss the use of Bayesian hierarchical models (within the analytical stage), due to their flexibility in dealing with the variability present in data from multiple scales. With growing recognition of both ecological drivers that span spatial and temporal scales and the subsequent need for collaboration to effectively manage heterogeneous resources, we expect implementation of transboundary approaches to become increasingly critical for effective inland fisheries management.

Science.gov (United States)

Chang, Shuhua; Qin, Weihua; Wang, Xinyu

2018-01-01

In this paper, we present a transboundary pollution game, in which emission permits trading and pollution abatement costs under learning by doing are considered. In this model, the abatement cost mainly depends on the level of pollution abatement and the experience of using pollution abatement technology. We use optimal control theory to investigate the optimal emission paths and the optimal pollution abatement strategies under cooperative and noncooperative games, respectively. Additionally, the effects of parameters on the results have been examined.

Othman, Jamal; Sahani, Mazrura; Mahmud, Mastura; Sheikh Ahmad, Md Khadzir

2014-01-01

This study assessed the economic value of health impacts of transboundary smoke haze pollution in Kuala Lumpur and adjacent areas in the state of Selangor, Malaysia. Daily inpatient data from 2005, 2006, 2008, and 2009 for 14 haze-related illnesses were collected from four hospitals. On average, there were 19 hazy days each year during which the air pollution levels were within the Lower Moderate to Hazardous categories. No seasonal variation in inpatient cases was observed. A smoke haze occurrence was associated with an increase in inpatient cases by 2.4 per 10,000 populations each year, representing an increase of 31 percent from normal days. The average annual economic loss due to the inpatient health impact of haze was valued at MYR273,000 ($91,000 USD). - Highlights: • Transboundary smoke haze is an annual phenomenon in Malaysia. • No evidence of seasonal factors in smoke haze related inpatient cases. • Inpatient rates during a haze event increased by 31% relative to normal days. • Annual economic loss due to inpatient health impact of haze valued at $91,000. • Present value of economic loss estimated at $1.1 million to $1.7 million. - Inpatient rates soared by 31% while economic loss valued at USD91,000 annually

Cooperative and adaptive transboundary water governance in Canada's Mackenzie River Basin: status and prospects

Directory of Open Access Journals (Sweden)

Michelle Morris

2016-03-01

Full Text Available Canada's Mackenzie River Basin (MRB is one of the largest relatively pristine ecosystems in North America. Home to indigenous peoples for millennia, the basin is also the site of increasing resource development, notably fossil fuels, hydroelectric power resources, minerals, and forests. Three provinces, three territories, the Canadian federal government, and Aboriginal governments (under Canada's constitution, indigenous peoples are referred to as "Aboriginal" have responsibilities for water in the basin, making the MRB a significant setting for cooperative, transboundary water governance. A framework agreement that provides broad principles and establishes a river basin organization, the MRB Board, has been in place since 1997. However, significant progress on completing bilateral agreements under the 1997 Mackenzie River Basin Transboundary Waters Master Agreement has only occurred since 2010. We considered the performance of the MRB Board relative to its coordination function, accountability, legitimacy, and overall environmental effectiveness. This allowed us to address the extent to which governance based on river basin boundaries, a bioregional approach, could contribute to adaptive governance in the MRB. Insights were based on analysis of key documents and published studies, 19 key informant interviews, and additional interactions with parties involved in basin governance. We found that the MRB Board's composition, its lack of funding and staffing, and the unwillingness of the governments to empower it to play the role envisioned in the Master Agreement mean that as constituted, the board faces challenges in implementing a basin-wide vision. This appears to be by design. The MRB governments have instead used the bilateral agreements under the Master Agreement as the primary mechanism through which transboundary governance will occur. A commitment to coordinating across the bilateral agreements is needed to enhance the prospects for

Legal issues in the transboundary movement of radioactive waste

International Nuclear Information System (INIS)

Pelzer, N.

2000-01-01

The transboundary movement of radioactive waste is a politically sensitive issue, which implies the raising of complex legal questions. Transborder transportation may be governed by various national jurisdictions on its way from the State of origin via the transit States to the State of destination. The overall goal to be achieved is safe management during all the necessary steps of transport, handling, storage and disposal. Far-reaching approximation or harmonization of national law applicable is to be aimed at in order to facilitate transboundary movement. Article 27 of the 1997 Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management (Joint Convention) provides for a regime which, in principle, is appropriate. However, there are still open questions and, perhaps, lacunae remaining. Low risk materials exempt or released from regulatory control create specific problems owing to the fact that there are no agreed exemption or clearance levels which could be the base for unified legal provisions. The carrier may face different levels from State to State. The movement of radioactive waste by sea or air outside national jurisdictions is governed by the rules of Public International Law, especially by the 1982 United Nations Convention on the Law of the Sea, which in major parts is a codification of existing International Customary Law. During transport on the high seas, the ship is under the jurisdiction of the State under which flag she is sailing. If the nuclear cargo is loaded onto a ship sailing under the flag of a non-contracting party to the Joint Convention, there may be legal problems with regard to whether and to what extent the Joint Convention is applicable, even if the State of origin or the State of destination is a contracting party to the Joint Convention. If a nuclear incident occurs during the movement of the waste, complicated questions of nuclear liability law will have to be solved. As far as the

As part of our regular Coordinated Research Project (CRP) activities and our technical support given to ongoing national and regional Technical Cooperation projects (TCPs), the Section evaluated our activities as part of the Agency's 2004/2005 midterm performance evaluation. During this exercise we could identify areas where good performances were achieved as well as those where further improvements were needed and which we then addressed. It became apparent that more proactive measures are needed towards the detection, control and management of emerging diseases, with particular emphasis on transboundary animal diseases and the offering of relevant support to Member States. A particular case in point is the current avian influenza situation. This issue discussed the problem posed by rinderpest and the Agency's effort in eradicating this viral disease

Articulating a trans-boundary infrastructure supply chain greenhouse gas emission footprint for cities: Mathematical relationships and policy relevance

International Nuclear Information System (INIS)

Chavez, Abel; Ramaswami, Anu

2013-01-01

This paper compares the policy relevance and derives mathematical relationships between three approaches for GHG emissions accounting for cities. The three approaches are: (a) Purely-Geographic Inventory, (b) Trans-boundary Community-Wide Infrastructure Footprint (CIF), and (c) Consumption-Based Footprint (CBF). Mathematical derivations coupled with case study of three US communities (Denver Colorado, Routt Colorado, and Sarasota Florida), shows that no one method provides a larger or more holistic estimate of GHG emissions associated with communities. A net-producing community (Routt) demonstrates higher CIF GHG emissions relative to the CBF, while a net-consuming community (Sarasota) yields the opposite. Trade-balanced communities (Denver) demonstrate similar numerical estimates of CIF and CBF, as predicted by the mathematical equations. Knowledge of community typology is important in understanding trans-boundary GHG emission contributions

Effects and control of long-range transboundary air pollution. Report prepared within the framework of the Convention on Long-range Transboundary Air Pollution

International Nuclear Information System (INIS)

1994-01-01

This tenth volume of the series of Air Pollution Studies, published under the auspices of the Executive Body for the Convention on Long-range Transboundary Air Pollution, contains the documents reviewed and approved for publication at the eleventh session of the Executive Body held at Geneva from 1 to 3 December 1993. Part One is the Annual Review of Strategies and Policies for Air Pollution Abatement. National emission data and forecasts for sulphur dioxide (SO 2 ), nitrogen oxides (NO x ), volatile organic compounds (VOCs), ammonia (NH 3 ) and carbon dioxide (CO 2 ) from 1980 to 2005 are presented. Conclusions are drawn concerning the status of implementation of the sulphur and nitrogen oxides protocols on the basis of these data. Part Two is an executive summary of the 1992 Report on the Forest Condition in Europe. The main objective of this report is to give a condensed description of the condition of forests in Europe, as it has been assessed by the transnational and national annual surveys, carried out jointly by the ECE under the Convention on Long-range Transboundary Air Pollution and by the European Community (EC). Part Three is a summary report that focuses on the reduction of air pollution from heat and electric energy production. It is based on discussion papers submitted to the fifth ECE Seminar on Emission Control Technology for Stationary Sources, held in Nuremberg (Germany) from 10 to 14 June 1991. This chapter presents the main control techniques to reduce emissions from fuel combustion, which is a major contribution in most ECE countries to air pollution by sulphur and nitrogen compounds, carbon oxides, organic compounds, as well as heavy metals. Three principal abatement options are reviewed: fuel cleaning and fuel conversion, low-emission combustion processes, and flue gas cleaning processes. Both technical and economic aspects of the different measures are discussed

Application of new vaccine technologies for the control of transboundary diseases.

Science.gov (United States)

Swayne, D E

2004-01-01

Vaccines have played an important role in the control of diseases of livestock and poultry, including Transboundary Diseases. In the future, vaccines will play a greater role in controlling these diseases. Historically, inactivated whole viruses in various adjuvant systems have been used and will continue to be used in the near future. For the future, emerging technologies will allow targeted use of only the protective antigens of the pathogen and will provide the opportunity for differentiating between vaccinated and field-exposed animals. Furthermore, the expression of cytokines by vaccines will afford earlier or greater enhancement of protection than can be achieved by the protective response elicited by the antigenic epitopes of the pathogen alone. Avian influenza (AI) is a good case for studying future trends in vaccine design and use. Inactivated AI virus (AIV) vaccines will continue as the primary vaccines used over the next 10 years. These vaccines will use homologous haemagglutinin sub-types, either from the use of field strains or the generation of new strains through the use of infectious clones produced in the laboratory. The latter will allow creation of high growth reassortants, which will provide consistent high yields of antigen and result in potent vaccines. New viral and bacterial vectors with inserts of AIV haemagglutinin gene will be developed and potentially used in the field. Such new vectors will include herpesvirus-turkey, infectious laryngotracheitis virus, adenoviruses, various types of paramyxoviruses and Salmonella sp. In addition, there is a theoretical possibility of gene-deleted mutants that would allow the use of live AIV vaccines, but the application of such vaccines has inherent dangers for gene reassortment with field viruses in the generation of disease-causing strains. Subunit haemagglutinin protein and DNA haemagglutinin gene vaccines are possible, but with current technologies, the cost is prohibitive. In the future, effective

Coordination of environmental policy for transboundary environmental problems?

Energy Technology Data Exchange (ETDEWEB)

Hoel, M.

1996-01-01

In order to reach a Pareto optimal outcome with transboundary environmental problems, there must be some kind of international agreement. One possibility would be an international agreement focusing directly on emissions in each country. Given such an agreement, an important issue is whether one should supplement the agreement with some kind of policy coordination, or if the choice of environmental policies should be left for each country to decide for itself. The present paper shows that under ``ideal`` conditions, policies need not be coordinated across countries. Such ideal conditions include, among other things, that all markets, including the labour market, are competitive. However, if one has imperfect competition in goods markets, or unemployment, it may be desirable to let an international environmental agreement not only specify emission levels, but also the policy mix between emission taxes and direct regulation. 16 refs.

Forecasting the Depletion of Transboundary Groundwater Resources in Hyper-Arid Environments

Science.gov (United States)

Mazzoni, A.; Heggy, E.

2014-12-01

The increase in awareness about the overexploitation of transboundary groundwater resources in hyper-arid environments that occurred in the last decades has highlighted the need to better map, monitor and manage these resources. Climate change, economic and population growth are driving forces that put more pressure on these fragile but fundamental resources. The aim of our approach is to address the question of whether or not groundwater resources, especially non-renewable, could serve as "backstop" water resource during water shortage periods that would probably affect the drylands in the upcoming 100 years. The high dependence of arid regions on these resources requires prudent management to be able to preserve their fossil aquifers and exploit them in a more sustainable way. We use the NetLogo environment with the FAO Aquastat Database to evaluate if the actual trends of extraction, consumption and use of non-renewable groundwater resources would remain feasible with the future climate change impacts and the population growth scenarios. The case studies selected are three: the Nubian Sandstone Aquifer System, shared between Egypt, Libya, Sudan and Chad; the North Western Sahara Aquifer System, with Algeria, Tunisia and Libya and the Umm Radhuma Dammam Aquifer, in its central part, shared between Saudi Arabia, Qatar and Bahrain. The reason these three fossil aquifers were selected are manifold. First, they represent properly transboundary non-renewable groundwater resources, with all the implications that derive from this, i.e. the necessity of scientific and socio-political cooperation among riparians, the importance of monitoring the status of shared resources and the need to elaborate a shared management policy. Furthermore, each country is characterized by hyper-arid climatic conditions, which will be exacerbated in the next century by climate change and lead to probable severe water shortage periods. Together with climate change, the rate of population

New animal model of emotional stress: Behavioral, neuroendocrine and immunological consequences

LIN Wenjuan; WANG Weiwen; SHAO Feng

2003-01-01

This report describes a new model of emotional stress, which was induced by randomly giving an empty water bottle to rats during watering periods per day for 14 consecutive days. The behavioral, endocrinological and immunological consequences were investigated. The data showed that the emotional stress activated both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system, leading to the increased blood levels of corticosterone and catecholamine. It also elicited attacking and exploring behavior, suppressed the immune function of the rats, including leukocyte counts, weight of the spleen, and the level of specific anti-ovalbumin IgG antibody production. Presenting no water and no empty bottle to rats only evoked the exploring behavior, increased the corticosterone level and decreased the leukocyte counts. These findings demonstrate a role of psychological factors on behavioral, endocrinological and immunological functioning. The animal model described in the present study may serve as an analogue mimicking emotional stress experienced in humans (e.g. anger and/or anxiety), and may be useful for further studying the complex relationships among emotional stress, behavior, and immune function.

Transboundary Movements of Genetically Modified Organisms and the Cartagena Protocol: Key Issues and Concerns

Directory of Open Access Journals (Sweden)

2014-12-01

Full Text Available Biotechnology or the engineering of the genetic material of species can give way to avenues of possibilities for the benefit of people, fauna and flora but also has the potential of posing untold and undiscovered threats to human beings and other living organisms. One of the first attempts to legislate on international rules on biotechnology can be traced back to article 19 of the Convention on Biological Diversity (CBD in 1992. The CBD is indeed the first international legal instrument apart from the then European Community’s relevant directives to suggest that biotechnology is a matter of concern for the international community while providing a basis upon which more detailed procedures would be elaborated in the field of biosafety. While the CBD includes international rules on access to genetic resources, access to and the transfer of technology, the handling of biotechnology and the distribution of its benefits, it does not include a detailed regulation on genetically modified organisms (GMOs and their possible adverse effects on the environment, human and animal health. It was only with the coming into existence of the Cartagena Protocol on Biosafety (Cartagena Protocol to the CBD in 2000 that the safe transfer, handling and use of living modified organisms (LMOs such as genetically engineered plants, animals, and microbes were at last being catered for, albeit leaving aside the broader categories of GMOs. Due to the need for the negotiators of this protocol to make compromises, there were still key issues on the international biosafety framework pertaining mainly to the scope of the GMOs to be covered by this protocol and by the Advanced Informed Agreement procedure; identification and traceability issues; and liability and redress issues. Nine years after the entry into force of the Cartagena Protocol the transboundary movements of GMOs have clearly increased with new categories of GMOs and genetically modified products to regulate.

Full Text Available Due to more efficient use of feed, many farms, ensuring high productivity, has reached the profitability of milk production 40 % or more. No wonder milk has recently been called "white gold" because it provides the highest profitability among livestock products. However, higher producing cows have higher requirements for balanced feeding. Such cows are more intense metabolism: compared to cows of average productivity, the gas exchange is increased in 1,5-2 times, also increases blood pressure, pulse rate and respiration. This means that the wear and tear of the body is faster. And the consequences of inadequate feeding due to unbalanced diets on nutritional and biological active substances lead to profound metabolic disorders, which leads to disruption of the function of reproduction, diseases, shortening productive use of animals to one or two lactations. Without a system of introduction of achievements of zoo technical and veterinary Sciences, the proper organization of feeding, housing and care, application of progressive forms of work organization - cannot be opened, laid in the animals genetic potential. The main direction in the development of dairy cattle breeding is its intensification. The effectiveness of intensification is the implementation of the following development paths: full implementation and improvement of the genetic potential of dairy cattle; rich, biologically full feeding of animals; preparation of sufficient high-quality feed; implementation of efficient technologies.

Lead isotope ratios in six lake sediment cores from Japan Archipelago: Historical record of trans-boundary pollution sources

International Nuclear Information System (INIS)

Hosono, Takahiro; Alvarez, Kelly; Kuwae, Michinobu

2016-01-01

Sediment cores from six lakes situated from north to south on the Japanese Archipelago were collected during 2009–2010 to investigate the hypothesis that deposition of lead (Pb) was coming from East Asia (including China, South Korea and eastern part of Russia). Accumulation rates and ages of the lake sediment were estimated by the "2"1"0Pb constant rate of supply model and "1"3"7Cs inputs to reconstruct the historical trends of Pb accumulation. Cores from four lakes located in the north and central Japan, showed clear evidence of Pb pollution with a change in the "2"0"6Pb/"2"0"7Pb and "2"0"8Pb/"2"0"7Pb ratios in the recent sediment as compared to the deeper sediment. Among the six studied lakes, significant inputs of anthropogenic lead emissions were observed at Lake Mikazuki (north Hokkaido in north Japan), Lake Chokai (north of Honshu), and Lake Mikuriga (central part of Honshu). Pb isotopic comparison of collected core sediment and previously reported data for wet precipitation and aerosols from different Asian regions indicate that, before 1900, Pb accumulated in these three lakes was not affected by trans-boundary sources.

Sediment cores from six lakes situated from north to south on the Japanese Archipelago were collected during 2009–2010 to investigate the hypothesis that deposition of lead (Pb) was coming from East Asia (including China, South Korea and eastern part of Russia). Accumulation rates and ages of the lake sediment were estimated by the {sup 210}Pb constant rate of supply model and {sup 137}Cs inputs to reconstruct the historical trends of Pb accumulation. Cores from four lakes located in the north and central Japan, showed clear evidence of Pb pollution with a change in the {sup 206}Pb/{sup 207}Pb and {sup 208}Pb/{sup 207}Pb ratios in the recent sediment as compared to the deeper sediment. Among the six studied lakes, significant inputs of anthropogenic lead emissions were observed at Lake Mikazuki (north Hokkaido in north Japan), Lake Chokai (north of Honshu), and Lake Mikuriga (central part of Honshu). Pb isotopic comparison of collected core sediment and previously reported data for wet precipitation and aerosols from different Asian regions indicate that, before 1900, Pb accumulated in these three lakes was not affected by trans-boundary sources. Lake Mikazuki started to receive Pb emissions from Russia in early 1900s, and during the last two decades, this lake has been affected by trans-boundary Pb pollution from northern China.

In 2007 HELCOM launched a plan for transboundary management of the Baltic Sea. This plan, called the Baltic Sea Action Plan (BSAP), aims amongst other things, to reduce eutrophication in the different regions of the Baltic Sea by reducing incoming nutrient loads from all discharging drainage basins...... difficult to achieve, and that additional abatement measures are likely to be required to fulfil these targets. The minimised total cost of delivering the achievable load reductions across the 9 Baltic littoral countries is estimated to be 4.69 billion Euros, annually, with substantial differences...

Results of radioecological investigation of Central Asian rivers are presented. Investigation was done as part of the Navruz Project, a cooperative, transboundary river monitoring project involving rivers and institutions in Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan, and facilitated by Sandia National Laboratories in the United States. The study of waterborne radionuclides and metals concentrations in Central Asia is of particular interest because of the history of nuclear materials mining, fabrication, transport, and storage there, when it was part of the Soviet Union. This development left a legacy of radionuclides and metals contamination in some Central Asian regions, which poses a clear health hazard to populations who rely heavily upon surface water for agricultural irrigation and direct domestic consumption.

Full Text Available All distinctions in the economic and nature protection policy of the neighboring states are well reflected and shown within trans-boundary river basins. The parts of trans-boundary geosystem of one country can experience an essential negative influence from rash decisions in the field of nature use and nature protection policy of the neighboring state. The Amur River Basin covers the territories of Russia, the Peoples Republic of China, Mongolia and Democratic People’s Republic of Korea and occupies more than 2 million km2. The most intensive development of the basin territory has started since the middle of the 19th century. We compiled two maps of land use in the Amur River basin in the 1930–1940s and in the early 21st century. Results showed that, negative dynamics is marked for forest lands, meadows, wetlands and mountain tundra. The basic features in the change of land use within national parts of the basin in Russia, China and Mongolia are analyzed. The comparative analysis of land use peculiarities of the countries for the last 70 years has been done.

2015-01-01

Transboundary industrial pollution requires international actions to control its formation and effects. In this paper, we present a stochastic differential game to model the transboundary industrial pollution problems with emission permits trading. More generally, the process of emission permits price is assumed to be stochastic and to follow a geometric Brownian motion (GBM). We make use of stochastic optimal control theory to derive the system of Hamilton-Jacobi-Bellman (HJB) equations satisfied by the value functions for the cooperative and the noncooperative games, respectively, and then propose a so-called fitted finite volume method to solve it. The efficiency and the usefulness of this method are illustrated by the numerical experiments. The two regions' cooperative and noncooperative optimal emission paths, which maximize the regions' discounted streams of the net revenues, together with the value functions, are obtained. Additionally, we can also obtain the threshold conditions for the two regions to decide whether they cooperate or not in different cases. The effects of parameters in the established model on the results have been also examined. All the results demonstrate that the stochastic emission permits prices can motivate the players to make more flexible strategic decisions in the games.

Code of practice on the international transboundary movement of radioactive waste

International Nuclear Information System (INIS)

1990-11-01

This Code of Practice should serve as guidelines of the IAEA to the States for the development and harmonization of policies and laws on the international transboundary movement of radioactive wastes. It relies on international standards for the safe transport of radioactive material and the physical protection of nuclear material, as well as the standards for basic nuclear safety and radiation protection and radioactive waste management; it does not establish separate guidance in these areas. Furthermore, this Code, which is advisory, does not affect in any way existing and future arrangements among States which relate to matters covered by it and are compatible with its objectives

Transboundary Air-Pollution Transport in the Czech-Polish Border Region between the Cities of Ostrava and Katowice.

2016-12-01

The Czech Hydrometeorological Institute (CHMI) estimated the transboundary transport of air pollution between the Czech Republic and Poland by assessing relationships between weather conditions and air pollution in the area as part of the "Air Quality Information System in the Polish-Czech border of the Silesian and Moravian-Silesian region" project (http://www.air-silesia.eu). Estimation of cross-border transport of pollutants is important for Czech-Polish negotiations and targeted measures for improving air quality. Direct measurement of PM 10 and sulphur dioxide (SO 2 ) concentrations and the direction and wind speed from measuring stations in the vicinity of the Czech-Polish state border in 2006-2012. Taking into account all the inaccuracies, simplifications and uncertainties, by which all of the measurements are affected, it is possible to state that the PM 10 transboundary transport was greater from the direction of Poland to the Czech Republic, rather than the other way around. Nevertheless, the highest share of the overall PM 10 concentration load was recorded on days with a vaguely estimated airflow direction. This usually included days with changing wind direction or days with a distinct wind change throughout the given day. A changeable wind is most common during low wind speeds. It can be assumed that during such days with an ambiguous daily airflow, the polluted air saturated with sources on both sides of the border moves from one country to the other. Therefore, we could roughly ascribe an equal level of these concentrations to both the Czech and Polish side. PM 10 transboundary transport was higher from Poland to the Czech Republic than from the opposite direction, despite the predominant air flow from the Czech Republic to Poland.

Simulation of Intra- or transboundary surface-water-rights hierarchies using the farm process for MODFLOW-2000

Science.gov (United States)

Schmid, W.; Hanson, R.T.

2007-01-01

Water-rights driven surface-water allocations for irrigated agriculture can be simulated using the farm process for MODFLOW-2000. This paper describes and develops a model, which simulates routed surface-water deliveries to farms limited by streamflow, equal-appropriation allotments, or a ranked prior-appropriation system. Simulated diversions account for deliveries to all farms along a canal according to their water-rights ranking and for conveyance losses and gains. Simulated minimum streamflow requirements on diversions help guarantee supplies to senior farms located on downstream diverting canals. Prior appropriation can be applied to individual farms or to groups of farms modeled as "virtual farms" representing irrigation districts, irrigated regions in transboundary settings, or natural vegetation habitats. The integrated approach of jointly simulating canal diversions, surface-water deliveries subject to water-rights constraints, and groundwater allocations is verified on numerical experiments based on a realistic, but hypothetical, system of ranked virtual farms. Results are discussed in light of transboundary water appropriation and demonstrate the approach's suitability for simulating effects of water-rights hierarchies represented by international treaties, interstate stream compacts, intrastate water rights, or ecological requirements. ?? 2007 ASCE.

2005-01-01

In March of 2000, scientists from four nuclear physics research institutes in the Central Asia Republics of Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan, and the U.S. Sandia National Laboratories embarked on a three-year cooperative transboundary river monitoring experiment. The experiment, named Navruz (meaning 'new beginning'), uses standardized methods to monitor basic water quality parameters, radionuclides, and metals in the Syr Darya and Amu Darya rivers. Overall, the project addresses three main goals: (1) to help increase capabilities in Central Asian nations for sustainable water resources management; (2) to provide a scientific basis for supporting nuclear transparency and non-proliferation in the region; and (3) to help reduce the threat of conflict in Central Asia over water resources. Contamination of these rivers is a result of growing population, urbanization, agricultural uses, and radioactive and metals contamination from a legacy of uranium mining, industry, and other activities of the former Soviet Union. The project focuses on waterborne radionuclides and metals because of the importance of these contaminants to public health and political stability in Central Asia. Moreover, the method of enabling scientists from bordering countries to study a transboundary problem, can lead to a greater scientific understanding, consensus on necessary mitigation steps, and ultimately the political resolution of the issue. The project scope, approach, and preliminary results are presented. (author)

The Supply Chain’s Role in Improving Animal Welfare

Science.gov (United States)

Harvey, David; Hubbard, Carmen

2013-01-01

Simple Summary The ability of supply chains to deliver high(er) levels and standards of animal welfare is subject to two critical conditions: (a) the innovative and adaptive capacity of actors in the chain to respond to society’s demands; (b) consumers actually buying animal-friendly products. Unless citizens are willing to support suppliers who comply with high(er) standards, their votes for better animal welfare risk exporting poor animal welfare to other countries with less rigorous standards. The logic of market failure in the case of animal welfare points to the superiority of consumer subsidies over producer subsidies to deliver improved animal welfare. Abstract Supply chains are already incorporating citizen/consumer demands for improved animal welfare, especially through product differentiation and the associated segmentation of markets. Nonetheless, the ability of the chain to deliver high(er) levels and standards of animal welfare is subject to two critical conditions: (a) the innovative and adaptive capacity of the chain to respond to society’s demands; (b) the extent to which consumers actually purchase animal-friendly products. Despite a substantial literature reporting estimates of willingness to pay (WTP) for animal welfare, there is a belief that in practice people vote for substantially more and better animal welfare as citizens than they are willing to pay for as consumers. This citizen-consumer gap has significant consequences on the supply chain, although there is limited literature on the capacity and willingness of supply chains to deliver what the consumer wants and is willing to pay for. This paper outlines an economic analysis of supply chain delivery of improved standards for farm animal welfare in the EU and illustrates the possible consequences of improving animal welfare standards for the supply chain using a prototype belief network analysis.

Marsh, T L; Pendell, D; Knippenberg, R

2017-04-01

For animal disease events the outcomes and consequences often remain unclear or uncertain, including the expected changes in benefits (e.g. profit to firms, prices to consumers) and in costs (e.g. response, clean-up). Moreover, the measurement of changes in benefits and costs across alternative interventions used to control animal disease events may be inexact. For instance, the economic consequences of alternative vaccination strategies to mitigate a disease can vary in magnitude due to trade embargoes and other factors. The authors discuss the economic measurement of animal disease outbreaks and interventions and how measurement is used in private and public decision-making. Two illustrative case studies in the United States of America are provided: a hypothetical outbreak of foot and mouth disease in cattle, and the 2014-2015 outbreak of highly pathogenic avian influenza in poultry.

The transboundary EIA convention in the context of private sector operations co-financed by an International Financial Institution: two case studies from Azerbaijan and Turkmenistan

International Nuclear Information System (INIS)

Nazari, Mehrdad M.

2003-01-01

This paper presents two case studies involving private sector, offshore, oil field developments in the Caspian Sea. Environmental Impact Assessments (EIAs) of these operations indicated that major and unmitigated oil spills could potentially result in transboundary impacts. Both projects were co-financed by the European Bank for Reconstruction and Development (EBRD), an International Financial Institution (IFI). Project review and financing decision by the EBRD occurred when neither country hosting the projects was a Party to the 1991 Convention on EIA in a Transboundary Context (Espoo Convention). Discussions with government agencies during project review highlighted their limited institutional capacity to pursue transboundary notification and consultation activities. However, without being formal Parties or having clearly defined roles under the Convention, the combined presence of the EBRD, the private sector developer and its project needing financing became important drivers to promote the Espoo Convention. Surveying for similar IFI-project combinations in developing and transition economies could provide a 'bottom up' input to further optimise the Convention Secretariat's awareness raising, intervention design, and alliance-building strategies. The knowledge management model and user-friendly Web site of the 1992 Convention on Biological Diversity highlight approaches that may also prove effective for the Espoo Convention

Within the framework of the "Governance of Groundwater Resources in Transboundary Aquifers" (GGRETA) project, funded by the Swiss Agency for Development and Cooperation (SDC), the Governments of Botswana, Namibia and South Africa, jointly with the UNESCO International Hydrological Programme (UNESCO-IHP) are undertaking an assessment of the Stampriet Transboundary Aquifer System (STAS). The importance of the STAS to the region draws from the fact that it is the only permanent and dependable water resource in the area, which covers 87000 km2 from Central Namibia into Western Botswana and South Africa's Northern Cape Province. The first phase of the project (2013-2015) focused on an assessment of the STAS which allowed establishing a shared science based understanding of the resource. The activities of the second phase of the project (2016-2018) will consolidate the technical results achieved and the tools developed in the first phase, and will strengthen capacity on groundwater governance at the national and transboundary levels to support the process of establishment of a multi-country cooperation mechanism (MCCM). The establishment of the STAS MCCM would be the first example of a mechanism for the management and governance of a transboundary aquifer in Southern Africa. The joint development of a numerical model is crucial to foster such cooperation as it provides a baseline for the formulation of sound policies for the governance of the STAS. The model is being developed through the application of the FREEWAT platform (within the H2020 FREEWAT project - FREE and open source software tools for WATer resource management; Rossetto et al., 2015), an open source and public domain GIS-integrated modelling environment for the simulation of the hydrological cycle. The FREEWAT project aims at improving water resource management by simplifying the application of water-related regulations through the use of modeling environments and GIS tools for storage, management and

Hosono, Takahiro; Alvarez, Kelly; Kuwae, Michinobu

2016-07-15

Sediment cores from six lakes situated from north to south on the Japanese Archipelago were collected during 2009-2010 to investigate the hypothesis that deposition of lead (Pb) was coming from East Asia (including China, South Korea and eastern part of Russia). Accumulation rates and ages of the lake sediment were estimated by the (210)Pb constant rate of supply model and (137)Cs inputs to reconstruct the historical trends of Pb accumulation. Cores from four lakes located in the north and central Japan, showed clear evidence of Pb pollution with a change in the (206)Pb/(207)Pb and (208)Pb/(207)Pb ratios in the recent sediment as compared to the deeper sediment. Among the six studied lakes, significant inputs of anthropogenic lead emissions were observed at Lake Mikazuki (north Hokkaido in north Japan), Lake Chokai (north of Honshu), and Lake Mikuriga (central part of Honshu). Pb isotopic comparison of collected core sediment and previously reported data for wet precipitation and aerosols from different Asian regions indicate that, before 1900, Pb accumulated in these three lakes was not affected by trans-boundary sources. Lake Mikazuki started to receive Pb emissions from Russia in early 1900s, and during the last two decades, this lake has been affected by trans-boundary Pb pollution from northern China. Lake Chokai has received Pb pollutant from northern China since early 1900s until 2009, whereas for the Lake Mikuriga the major Pb contaminant was transported from southern China during the past 100years. The results of our study demonstrate that Japan Archipelago has received trans-boundary Pb emissions from different parts of East Asian region depending on location, and the major source region has changed historically.

Paratuberculosis (PTB) is a chronic disease which may lead to reduced milk yield, lower animal welfare and death in cattle. The causative agent is Mycobacterium avium subsp. paratuberculosis (MAP). The economic consequences are particularly important incentives in the control and eradication...... of the infection. One strategy to control PTB in a herd is to purchase animals from farms with a low risk of MAP infection. We wanted to investigate the epidemiological and economic consequences of buying livestock from different supplier farms of low, medium or high risk, as well as farms with unknown status. We...

The application of epidemiology in aquatic animal health -opportunities and challenges

Science.gov (United States)

2011-01-01

Over recent years the growth in aquaculture, accompanied by the emergence of new and transboundary diseases, has stimulated epidemiological studies of aquatic animal diseases. Great potential exists for both observational and theoretical approaches to investigate the processes driving emergence but, to date, compared to terrestrial systems, relatively few studies exist in aquatic animals. Research using risk methods has assessed routes of introduction of aquatic animal pathogens to facilitate safe trade (e.g. import risk analyses) and support biosecurity. Epidemiological studies of risk factors for disease in aquaculture (most notably Atlantic salmon farming) have effectively supported control measures. Methods developed for terrestrial livestock diseases (e.g. risk-based surveillance) could improve the capacity of aquatic animal surveillance systems to detect disease incursions and emergence. The study of disease in wild populations presents many challenges and the judicious use of theoretical models offers some solutions. Models, parameterised from observational studies of host pathogen interactions, have been used to extrapolate estimates of impacts on the individual to the population level. These have proved effective in estimating the likely impact of parasite infections on wild salmonid populations in Switzerland and Canada (where the importance of farmed salmon as a reservoir of infection was investigated). A lack of data is often the key constraint in the application of new approaches to surveillance and modelling. The need for epidemiological approaches to protect aquatic animal health will inevitably increase in the face of the combined challenges of climate change, increasing anthropogenic pressures, limited water sources and the growth in aquaculture.

The transboundary non-renewable Nubian Aquifer System of Chad, Egypt, Libya and Sudan: classical groundwater questions and parsimonious hydrogeologic analysis and modeling

Voss, Clifford I.; Soliman, Safaa M.

2014-03-01

Parsimonious groundwater modeling provides insight into hydrogeologic functioning of the Nubian Aquifer System (NAS), the world's largest non-renewable groundwater system (belonging to Chad, Egypt, Libya, and Sudan). Classical groundwater-resource issues exist (magnitude and lateral extent of drawdown near pumping centers) with joint international management questions regarding transboundary drawdown. Much of NAS is thick, containing a large volume of high-quality groundwater, but receives insignificant recharge, so water-resource availability is time-limited. Informative aquifer data are lacking regarding large-scale response, providing only local-scale information near pumps. Proxy data provide primary underpinning for understanding regional response: Holocene water-table decline from the previous pluvial period, after thousands of years, results in current oasis/sabkha locations where the water table still intersects the ground. Depletion is found to be controlled by two regional parameters, hydraulic diffusivity and vertical anisotropy of permeability. Secondary data that provide insight are drawdowns near pumps and isotope-groundwater ages (million-year-old groundwaters in Egypt). The resultant strong simply structured three-dimensional model representation captures the essence of NAS regional groundwater-flow behavior. Model forecasts inform resource management that transboundary drawdown will likely be minimal—a nonissue—whereas drawdown within pumping centers may become excessive, requiring alternative extraction schemes; correspondingly, significant water-table drawdown may occur in pumping centers co-located with oases, causing oasis loss and environmental impacts.

The Supply Chain’s Role in Improving Animal Welfare

Directory of Open Access Journals (Sweden)

David Harvey

2013-08-01

Full Text Available Supply chains are already incorporating citizen/consumer demands for improved animal welfare, especially through product differentiation and the associated segmentation of markets. Nonetheless, the ability of the chain to deliver high(er levels and standards of animal welfare is subject to two critical conditions: (a the innovative and adaptive capacity of the chain to respond to society’s demands; (b the extent to which consumers actually purchase animal-friendly products. Despite a substantial literature reporting estimates of willingness to pay (WTP for animal welfare, there is a belief that in practice people vote for substantially more and better animal welfare as citizens than they are willing to pay for as consumers. This citizen-consumer gap has significant consequences on the supply chain, although there is limited literature on the capacity and willingness of supply chains to deliver what the consumer wants and is willing to pay for. This paper outlines an economic analysis of supply chain delivery of improved standards for farm animal welfare in the EU and illustrates the possible consequences of improving animal welfare standards for the supply chain using a prototype belief network analysis.

Animal rights, animal minds, and human mindreading.

Science.gov (United States)

Mameli, M; Bortolotti, L

2006-02-01

Do non-human animals have rights? The answer to this question depends on whether animals have morally relevant mental properties. Mindreading is the human activity of ascribing mental states to other organisms. Current knowledge about the evolution and cognitive structure of mindreading indicates that human ascriptions of mental states to non-human animals are very inaccurate. The accuracy of human mindreading can be improved with the help of scientific studies of animal minds. However, the scientific studies do not by themselves solve the problem of how to map psychological similarities (and differences) between humans and animals onto a distinction between morally relevant and morally irrelevant mental properties. The current limitations of human mindreading-whether scientifically aided or not-have practical consequences for the rational justification of claims about which rights (if any) non-human animals should be accorded.

A first part of the presentation is devoted to the consequences of the severe accident in the 1986 Chernobyl NPP. It lead to a substantial radioactive contaminated of large parts of Europe and thus raised the awareness for off-site nuclear accident consequences. Spatial patterns of the (transient) contamination of the air and (persistent) contamination of the ground were studied by both measurements and model simulations. For a variety of reasons, ground contamination measurements have variability at a range of spatial scales. Results will be reviewed and discussed. Model simulations, including inverse modelling, have shown that the standard source term as defined in the ATMES study (1990) needs to be updated. Sensitive measurements of airborne activities still reveal the presence of low levels of airborne radiocaesium over the northern hemisphere which stems from resuspension. Over time scales of months and years, the distribution of radionuclides in the Earth system is constantly changing, for example relocated within plants, between plants and soil, in the soil, and into water bodies. Motivated by the permanent risk of transboundary impacts from potential major nuclear accidents, the multidisciplinary project flexRISK (see http://flexRISK.boku.ac.at) has been carried out from 2009 to 2012 in Austria to quantify such risks and hazards. An overview of methods and results of flexRISK is given as a second part of the presentation. For each of the 228 NPPs, severe accidents were identified together with relevant inventories, release fractions, and release frequencies. Then, Europe-wide dispersion and dose calculations were performed for 2788 cases, using the Lagrangian particle model FLEXPART. Maps of single-case results as well as various aggregated risk parameters were produced. It was found that substantial consequences (intervention measures) are possible for distances up to 500-1000 km, and occur more frequently for a distance range up to 100-300 km, which is in

A Very High Spatial Resolution Detector for Small Animal PET

International Nuclear Information System (INIS)

Kanai Shah, M.S.

2007-01-01

Positron Emission Tomography (PET) is an in vivo analog of autoradiography and has the potential to become a powerful new tool in imaging biological processes in small laboratory animals. PET imaging of small animals can provide unique information that can help in advancement of human disease models as well as drug development. Clinical PET scanners used for human imaging are bulky, expensive and do not have adequate spatial resolution for small animal studies. Hence, dedicated, low cost instruments are required for conducting small animal studies with higher spatial resolution than what is currently achieved with clinical as well as dedicated small animal PET scanners. The goal of the proposed project is to investigate a new all solid-state detector design for small animal PET imaging. Exceptionally high spatial resolution, good timing resolution, and excellent energy resolution are expected from the proposed detector design. The Phase I project was aimed at demonstrating the feasibility of producing high performance solid-state detectors that provide high sensitivity, spatial resolution, and timing characteristics. Energy resolution characteristics of the new detector were also investigated. The goal of the Phase II project is to advance the promising solid-state detector technology for small animal PET and determine its full potential. Detectors modules will be built and characterized and finally, a bench-top small animal PET system will be assembled and evaluated

Studies of a trans-boundary active fault that cuts through the border of Armenia to Georgia in the area of the Javakheti volcanic highland have been conducted since 2007. The studies have been implemented based on the ISTC 1418 and NATO SfP 983284 Projects. The Javakheti Fault is oriented to the north-northwest and consists of individual segments displaying clear left-stepping trend. Fault mechanism is represented by right-lateral strike-slip with normal-fault component. The fault formed distinct scarps, deforming young volcanic and glacial sediments. The maximum-size displacements are recorded in the central part of the fault and range up to 150-200 m by normal fault and 700-900 m by right-lateral strike-slip fault. On both flanks, fault scarps have younger appearance, and displacement size there decreases to tens of meters. Fault length is 80 km, suggesting that maximum fault magnitude is estimated at 7.3 according to the Wells and Coppersmith (1994) relation. Many minor earthquakes and a few stronger events (1088, Mw=6.4, 1899 Mw=6.4, 1912, Mw=6.4 and 1925, Mw=5.6) are associated with the fault. In 2011/2012, we conducted paleoseismological and archeoseismological studies of the fault. By two paleoseismological trenches were excavated in the central part of the fault, and on its northern and southern flanks. The trenches enabled recording at least three strong ancient earthquakes. Presently, results of radiocarbon age estimations of those events are expected. The Javakheti Fault may pose considerable seismic hazard for trans-boundary areas of Armenia and Georgia as its northern flank is located at the distance of 15 km from the Baku-Ceyhan pipeline.

International Court of Justice on Potential Transboundary Damage and its Consequences in Nuclear Law

International Nuclear Information System (INIS)

Cletienne, M.

2010-01-01

On 4 May 2006, Argentina filed in the International Court of Justice ('ICJ') an application instituting proceedings against Uruguay. Argentina claimed that Uruguay, by authorizing the construction of a pulp mill (the 'CMB mill') and the construction and commissioning of another pulp mill (the 'Orion mill'), breached its obligations under the 1975 Statute of the River Uruguay, a treaty between Argentina and Uruguay, notably the obligation to take all necessary measures for the optimum and rational utilisation of the River Uruguay. On 20 April 2010,1 the court rendered its decision settling this environmental dispute between Argentina and Uruguay. This paper will first summarize the judgement and then consider the main contribution of this decision to international environmental law, e.g. the recognition of an international customary rule to conduct an environmental impact assessment. Finally, the potential consequences of the decision in nuclear law will be addressed in the last part

How downstream sub-basins depend on upstream inflows to avoid scarcity: typology and global analysis of transboundary rivers

Countries sharing river basins are often dependent upon water originating outside their boundaries; meaning that without that upstream water, water scarcity may occur with flow-on implications for water use and management. We develop a formalisation of this concept drawing on ideas about the transition between regimes from resilience literature, using water stress and water shortage as indicators of water scarcity. In our analytical framework, dependency occurs if water from upstream is needed to avoid scarcity. This can be diagnosed by comparing different types of water availability on which a sub-basin relies, in particular local runoff and upstream inflows. At the same time, possible upstream water withdrawals reduce available water downstream, influencing the latter water availability. By developing a framework of scarcity and dependency, we contribute to the understanding of transitions between system regimes. We apply our analytical framework to global transboundary river basins at the scale of sub-basin areas (SBAs). Our results show that 1175 million people live under water stress (42 % of the total transboundary population). Surprisingly, the majority (1150 million) of these currently suffer from stress only due to their own excessive water use and possible water from upstream does not have impact on the stress status - i.e. they are not yet dependent on upstream water to avoid stress - but could still impact on the intensity of the stress. At the same time, 386 million people (14 %) live in SBAs that can avoid stress owing to available water from upstream and have thus upstream dependency. In the case of water shortage, 306 million people (11 %) live in SBAs dependent on upstream water to avoid possible shortage. The identification of transitions between system regimes sheds light on how SBAs may be affected in the future, potentially contributing to further refined analysis of inter- and intrabasin hydro-political power relations and strategic planning

Daily rainfall statistics of TRMM and CMORPH: A case for trans-boundary Gandak River basin

Kumar, Brijesh; Patra, Kanhu Charan; Lakshmi, Venkat

Satellite precipitation products offer an opportunity to evaluate extreme events (flood and drought) for areas where rainfall data are not available or rain gauge stations are sparse. In this study, daily precipitation amount and frequency of TRMM 3B42V.7 and CMORPH products have been validated against daily rain gauge precipitation for the monsoon months (June-September or JJAS) from 2005-2010 in the trans-boundary Gandak River basin. The analysis shows that the both TRMM and CMORPH can detect rain and no-rain events, but they fail to capture the intensity of rainfall. The detection of precipitation amount is strongly dependent on the topography. In the plains areas, TRMM product is capable of capturing high-intensity rain events but in the hilly regions, it underestimates the amount of high-intensity rain events. On the other hand, CMORPH entirely fails to capture the high-intensity rain events but does well with low-intensity rain events in both hilly regions as well as the plain region. The continuous variable verification method shows better agreement of TRMM rainfall products with rain gauge data. TRMM fares better in the prediction of probability of occurrence of high-intensity rainfall events, but it underestimates intensity at high altitudes. This implies that TRMM precipitation estimates can be used for flood-related studies only after bias adjustment for the topography.

Proceedings of the High Consequence Operations Safety Symposium

Energy Technology Data Exchange (ETDEWEB)

1994-12-01

Many organizations face high consequence safety situations where unwanted stimuli due to accidents, catastrophes, or inadvertent human actions can cause disasters. In order to improve interaction among such organizations and to build on each others` experience, preventive approaches, and assessment techniques, the High Consequence Operations Safety Symposium was held July 12--14, 1994 at Sandia National Laboratories, Albuquerque, New Mexico. The symposium was conceived by Dick Schwoebel, Director of the SNL Surety Assessment Center. Stan Spray, Manager of the SNL System Studies Department, planned strategy and made many of the decisions necessary to bring the concept to fruition on a short time scale. Angela Campos and about 60 people worked on the nearly limitless implementation and administrative details. The initial symposium (future symposia are planned) was structured around 21 plenary presentations in five methodology-oriented sessions, along with a welcome address, a keynote address, and a banquet address. Poster papers addressing the individual session themes were available before and after the plenary sessions and during breaks.

We wanted to investigate the epidemiological and economic consequences of buying livestock from different supplier farms of low, medium or high risk, as well as farms with unknown status. We...... one, five or ten infected animals annually into an initially infection-free herd was also modeled. Our findings show that once infected, a farm can relatively safely purchase animals from other low and medium-risk farms without experiencing an increase in the prevalence, highlighting the importance...... of certification programmes. Furthermore, farms free of MAP are highly susceptible and cannot purchase more than a small number of animals per year without having a high risk of being infected. The probability of spontaneous fadeout after 10 years was 82% when introducing a single infected animal into an initially...

dynamics that favour non-equilibrium air transport mostly at daytime. The BL transport reaches at most 2\\cdot 106 km3/month in April-May during air export from Russia at the IR segment and re-import from China at the VL, respectively. A non-negligible BL air import from China into Russia occurs also over the IR segment throughout winter (at a 0.7-1.5 of 106 km3/month rate). Using the data from the stations of the Acid Deposition Monitoring Network in East Asia (EANET, www.eanet.asia), we estimate the transboundary pollution fluxes of S- and N-bearing gaseous compounds (SO2, NOx, etc.) and particulate matter (SO4-, ammonia nitrate). The co-occurrence of the high pollutants load and significant non-equilibrium air exchange renders pollutant net transport a rather non-linear problem. We derive the uncertainties associated with different assumptions on plum vertical location (i.e., in the BL-only vs. free troposphere). Finally, we derive the transient record of pollution transport for 2000-2015 for the IR and VL transboundary segments.

The Carboniferous Limestone groundwater extends from East to West across Belgium and the North of France (1420 km²). In a high population density and industrial activity region, it represents huge volumes of abstracted groundwater (98 Mm³). The aquifer thus constitutes a critical reserve for public distribution and industrial uses. This water reservoir is intensively exploited from both sides of the border since the end of the 19th century. Historically, this transboundary aquifer was overexploited, due to the massive requirements of the industry. As a consequence, a substantial piezometric level decrease was observed (up to 50 m). Due to the karstic nature of the aquifer, many sinkhole collapses were induced in the studied area. A reduction of the abstracted volumes was implemented in the 90s, which contributed to the relative stabilization of the piezometric levels, but the equilibrium remains uncertain. Due to complex political, urbanistic and industrial developments across this region, a reasonable and long-term management model was needed, involving all concerned countries and regions. Within the framework of the Interreg ScaldWIN Project, a belgo-french collaboration allowed the acquisition of new sets of geological and hydrogeological data. A new piezometric map was established and correlated with chemical and isotopic analyses. It enabled a more accurate knowledge on the main flow directions within the aquifer, and the relation between recharge area and the confined area, where groundwater is aged up to 10000 years. A new numerical model of the aquifer was implemented and calibrated by using the MARTHE code. This 4 layer-model includes a part of the French chalk aquifer and integrates all abstracted groundwater volumes (wells and quarries) from 1900 to 2010. Atmospheric and surface waters and potential evapotranspiration are included in relation to the groundwater. This model is used by the different partners to consider globally and locally the impact of

The international legal position on transboundary shipments of radioactive waste

International Nuclear Information System (INIS)

Grimston, M.C.

1997-01-01

The recent decision not to grant planning permission for construction of a Rock Characterisation Facility near Sellafield has reopened the question of long-term radioactive waste disposal policy in the UK. One possible solution would be the construction and operation of a small number of international radioactive waste disposal facilities, taking waste from several countries. Such an approach would allow pooling of international expertise; would allow the choice of excellent sites from geological and demographical standpoints; and may be economically attractive depending on economies of scale. However, the approach would also increase the amount of waste transport, and may reduce the pressure on producers to reduce the volumes of waste arising. This paper traces the development of international legal attitudes to transboundary transport of radioactive and other hazardous waste. It concludes that as international law now stands it would be very difficult to establish a network of international waste disposal facilities, and therefore strategies which are developed will be nationally based.

Water and Benefit Sharing in Transboundary River Basins

Science.gov (United States)

Arjoon, D.; Tilmant, A.; Herrmann, M.

2015-12-01

Growing water scarcity underlies the importance of cooperation for the effective management of river basins, particularly in the context of international rivers in which unidirectional externalities can lead to asymmetric relationships between riparian countries. Studies have shown that significant economic benefits can be expected through basin-wide cooperation, however, the equitable partitioning of these benefits over the basin is less well studied and tends to overlook the importance of stakeholder input in the definition of equitability. In this study, an institutional arrangement to maximize welfare and then share the scarcity cost in a river basin is proposed. A river basin authority plays the role of a bulk water market operator, efficiently allocating bulk water to the users and collecting bulk water charges which are then equitably redistributed among water users. This highly regulated market restrains the behaviour of water users to control externalities and to ensure basin-wide coordination, enhanced efficiency, and the equitable redistribution of the scarcity cost. The institutional arrangement is implemented using the Eastern Nile River basin as a case study. The importance of this arrangement is that it can be adopted for application in negotiations to cooperate in trans-boundary river basins. The benefit sharing solution proposed is more likely to be perceived as equitable because water users help define the sharing rule. As a result, the definition of the sharing rule is not in question, as it would be if existing rules, such as bankruptcy rules or cooperative game theory solutions, are applied, with their inherent definitions of fairness. Results of the case study show that the sharing rule is predictable. Water users can expect to receive between 93.5% and 95% of their uncontested benefits (benefits that they expect to receive if water was not rationed), depending on the hydrologic scenario.

An integrated model of water resources optimization allocation based on projection pursuit model - Grey wolf optimization method in a transboundary river basin

Under the effects of global change, water crisis ranks as the top global risk in the future decade, and water conflict in transboundary river basins as well as the geostrategic competition led by it is most concerned. This study presents an innovative integrated PPMGWO model of water resources optimization allocation in a transboundary river basin, which is integrated through the projection pursuit model (PPM) and Grey wolf optimization (GWO) method. This study uses the Songhua River basin and 25 control units as examples, adopting the PPMGWO model proposed in this study to allocate the water quantity. Using water consumption in all control units in the Songhua River basin in 2015 as reference to compare with optimization allocation results of firefly algorithm (FA) and Particle Swarm Optimization (PSO) algorithms as well as the PPMGWO model, results indicate that the average difference between corresponding allocation results and reference values are 0.195 bil m3, 0.151 bil m3, and 0.085 bil m3, respectively. Obviously, the average difference of the PPMGWO model is the lowest and its optimization allocation result is closer to reality, which further confirms the reasonability, feasibility, and accuracy of the PPMGWO model. And then the PPMGWO model is adopted to simulate allocation of available water quantity in Songhua River basin in 2018, 2020, and 2030. The simulation results show water quantity which could be allocated in all controls demonstrates an overall increasing trend with reasonable and equal exploitation and utilization of water resources in the Songhua River basin in future. In addition, this study has a certain reference value and application meaning to comprehensive management and water resources allocation in other transboundary river basins.

Data sharing in international transboundary contexts: The Vietnamese perspective on data sharing in the Lower Mekong Basin

Science.gov (United States)

Thu, Hang Ngo; Wehn, Uta

2016-05-01

Transboundary data sharing is widely recognised as a necessary element in the successful handling of water-related climate change issues, as it is a means towards integrated water resources management (IWRM). However, in practice it is often a challenge to achieve it. The Mekong River Commission (MRC), an inter-governmental agency established by Cambodia, Lao PDR, Thailand and Vietnam, has adopted IWRM in its water strategy plan in order to properly manage the transboundary waters of the Mekong River. In this context, data sharing procedures were institutionalised and have been officially implemented by the four member countries since 2001. This paper uses a systematic approach to identify the extent of data sharing and the factors influencing the willingness of key individuals in the Vietnam National Mekong Committee and its Primary Custodians to share data. We find that the initial objectives of the Procedures for Data and Information Exchange and Sharing (PDIES) have not been fully achieved and, further, that Vietnam has much to gain and little to lose by engaging in data sharing in the MRC context. The primary motivation for data sharing stems from the desire to protect national benefits and to prevent upstream countries from overexploiting the shared water resources. However, data sharing is hindered by a lack of national regulations in the Vietnam context concerning data sharing between state agencies and outdated information management systems.

New hydrological insights for the region: This analysis emphasizes the need for more scientific data, widespread education and training, and a more clearly defined governments’ role to manage groundwater at the international level. The study reviews the current legal framework and summarises the current scientific knowledge for the TAS with respect to the hydrologic and geologic framework as well as some of the major drivers for supply and demand. It also describes the links, approach and relevance of studies on the TAS to the UN Law of Transboundary Aquifers and on how these might fit in the regional strategy for the assessment and management of the TAS. Clear communication, shared knowledge and common objectives in the management of TAS will prepare the countries for future negotiations and cooperative binational programs.

Impacts of Climate Variability and Change on (Marine) Animals: Physiological Underpinnings and Evolutionary Consequences.

Science.gov (United States)

Pörtner, Hans O; Gutt, Julian

2016-07-01

Understanding thermal ranges and limits of organisms becomes important in light of climate change and observed effects on ecosystems as reported by the IPCC (2014). Evolutionary adaptation to temperature is presently unable to keep animals and other organisms in place; if they can these rather follow the moving isotherms. These effects of climate change on aquatic and terrestrial ecosystems have brought into focus the mechanisms by which temperature and its oscillations shape the biogeography and survival of species. For animals, the integrative concept of oxygen and capacity limited thermal tolerance (OCLTT) has successfully characterized the sublethal limits to performance and the consequences of such limits for ecosystems. Recent models illustrate how routine energy demand defines the realized niche. Steady state temperature-dependent performance profiles thus trace the thermal window and indicate a key role for aerobic metabolism, and the resulting budget of available energy (power), in defining performance under routine conditions, from growth to exercise and reproduction. Differences in the performance and productivity of marine species across latitudes relate to changes in mitochondrial density, capacity, and other features of cellular design. Comparative studies indicate how and why such mechanisms underpinning OCLTT may have developed on evolutionary timescales in different climatic zones and contributed to shaping the functional characteristics and species richness of the respective fauna. A cause-and-effect understanding emerges from considering the relationships between fluctuations in body temperature, cellular design, and performance. Such principles may also have been involved in shaping the functional characteristics of survivors in mass extinction events during earth's history; furthermore, they may provide access to understanding the evolution of endothermy in mammals and birds. Accordingly, an understanding is emerging how climate changes and

The hydroelectric power and potential environmental impacts of hydroelectric projects in 2 transboundary rivers in Turkey were assessed. The southeastern Anatolia project (GAP) is expected to encompass 27 dams and 19 hydroelectric power plants. The large-scale project will increase domestic electricity production and help to provide irrigation for large agricultural schemes. The Coruh project will consist of 27 dams and hydroelectric power plants, which are expected to have serious environmental impacts in both upstream Turkey and downstream Georgia. A slowing down of each river's velocity will cause changes in sediment transport, while the storage of water in large reservoirs will alter water quality and cause changes in local micro-climates. Irrigation methods may cause soil erosion and salinization. The construction of 2 GAP dams on the Tigris and Euphrates rivers has caused protest from Syria and Iraq. Economic development in the regions caused by the proposed hydroelectric projects is expected to have significant environmental impacts on woodland and grassland areas. The projects are expected to adversely affect threatened plant, mammal, and fish species. More detailed cumulative impact and environmental impact assessments are needed to evaluate the economic, environmental, and social problems that are likely to arise as a result of the projects. 17 refs., 3 tabs., 6 figs.

THE IMPORTANCE OF AFFECT TO BUILD CONSUMER TRUST IN HIGH-CONSEQUENCES EXCHANGES

2012-12-01

Full Text Available The present article investigates the importance of affect displayed by service provider to build consumer trust in high consequence exchanges. High-consequence exchanges are difficult situations in which the choices present a dilemma that can cause stress and severe emotional reactions (KAHN; LUCE, 2003. In this specific case, trust based on affect seems to become important; mainly because consumers may not have ability to evaluate the cognitive aspects of the situation, and moreover, a medical services failure can be highly problematic or even fatal (LEISEN; HYMAN, 2004. On the other hand, in low-consequence choices, we are predicting that cognition will be more important than affect in building trust. In this kind of situation, patients are more self-confident, less sensitive, and don’t perceive a high probability of loss (KUNREUTHER et al., 2002, and therefore focuses more on the rational outcomes.

Information on the Chernobyl NPP accident and its consequencies prepared for IAEA

Energy Technology Data Exchange (ETDEWEB)

1986-11-01

The information on the accident at the 4th power unit of the Chernobyl NPP and its consequences prepared for IAEA on the basis of the conclusions made by the Government commission constituted for investigating the accident causes and implementing the necessary emergency and reconstruction measures is given. The accident with reactor core disruption and partial destruction of the building Lappened on 26.04.86 at 1 hour and 23 minutes. The accident occurred before reactor shut-down for planned repairs during the testing of one of turbogenerators. The design features of the RBMK-1000 reactor plant, its main physical characteristics and parameters of the NPP safety system are considered. The chronology of the accident development and the results of analysis carried out using a mathematical model are given. The causes of the accident are analyzed. The measures for preventing the accident development and lessening its consequences as well as those for the environment radioactive contamination control and sanitary provisions are described in detail. The conclusion is made that the original cause of the accident is highly improbable combination of disorder and errors in operational conditions made by the personnel of the power unit. It is emphasized that development of the world nuclear engineering, besides advantages in the field of power supply and natural resources conservation, incurs also damages of international character. Among these are transboundary radioactivity transport, in particular, during serious radiation accidents and the danger of international terrorism and specific radiation hazard of nuclear objects under war conditions. All this defines the key necessity of deep international cooperation in the field of nuclear power engineering and its safeguarding.

Simulation of high consequence areas for gas pipelines

Directory of Open Access Journals (Sweden)

Orlando Díaz-Parra

2018-01-01

Full Text Available The gas pipeline is used for the transport of natural gas at a great distance. Risks derived from the handling of a combustible material transported under high pressure, by pipelines that pass close to where people live, makes it necessary to adopt prevention, mitigation and control measures to reduce the effect in case of ignition of a gas leak. This work shows the development of a new mathematical model to determine areas of high consequence and their application, using widely available and easy to use software, such as Google Earth and Excel, to determine and visualize the area up to which the level of radiation can affect the integrity of people and buildings. The model takes into account the pressure drop into the gas pipeline from the compression station, the gas leakage rate and possible forms of gas ignition. This development is an alternative to the use of specialized software and highly trained personnel. The simulation is applied to a traced of the Miraflores-Tunja gas pipeline, using a macro developed in Excel to determine the impact area and compare it with the coordinates of the vulnerable areas. The zones where these areas intersect are constituted in high consequence areas and are identified along with the sections of the pipeline that affect them, to provide the operator with a risk analysis tool for the determination and visualization of the gas pipeline and its environment.

Nitrate contamination of surface water and shallow groundwater was studied in transboundary (Russia/Ukraine) catchment with heterogeneous land use. Dominant sources of nitrate contamination were determined by applying a dual δ 15 N-NO 3 and δ 18 O-NO 3 isotope approach, multivariate statistics, and land use analysis. Nitrate concentration was highly variable from 0.25 to 22 mg L -1 in surface water and from 0.5 to 100 mg L -1 in groundwater. The applied method indicated that sewage to surface water and sewage and manure to groundwater were dominant sources of nitrate contamination. Nitrate/chloride molar ratio was added to support the dual isotope signature and indicated the contribution of fertilizers to the nitrate content in groundwater. Groundwater temperature was found to be an additional indicator of manure and sewerage leaks in the shallow aquifer which has limited protection and is vulnerable to groundwater pollution.

Exploring the Potential Impact of Serious Games on Social Learning and Stakeholder Collaborations for Transboundary Watershed Management of the St. Lawrence River Basin

Directory of Open Access Journals (Sweden)

2016-04-01

Full Text Available The meaningful participation of stakeholders in decision-making is now widely recognized as a crucial element of effective water resource management, particularly with regards to adapting to climate and environmental change. Social learning is increasingly being cited as an important component of engagement if meaningful participation is to be achieved. The exact definition of social learning is still a matter under debate, but is taken to be a process in which individuals experience a change in understanding that is brought about by social interaction. Social learning has been identified as particularly important in transboundary contexts, where it is necessary to reframe problems from a local to a basin-wide perspective. In this study, social learning is explored in the context of transboundary water resource management in the St. Lawrence River Basin. The overarching goal of this paper is to explore the potential role of serious games to improve social learning in the St. Lawrence River. To achieve this end, a two-pronged approach is followed: (1 Assessing whether social learning is currently occurring and identifying what the barriers to social learning are through interviews with the region’s water resource managers; (2 Undertaking a literature review to understand the mechanisms through which serious games enhance social learning to understand which barriers serious games can break down. Interview questions were designed to explore the relevance of social learning in the St. Lawrence River basin context, and to identify the practices currently employed that impact on social learning. While examples of social learning that is occurring have been identified, preliminary results suggest that these examples are exceptions rather than the rule, and that on the whole, social learning is not occurring to its full potential. The literature review of serious games offers an assessment of such collaborative mechanisms in terms of design principles

Southern European countries are often affected in summer by transboundary air pollution from Saharan dust. However, very few studies deal with Saharan dust pollution at high altitudes in winter. In Italy, the exceptional event occurred on February 19, 2014, colored in red the entire mountain range (Alps and Apennines) and allowed to characterize the particulate matter deposited on snow from a morphological and chemical point of view. Snow samples were collected after this event in four areas in the Alps and one in the Apennines. The particulate matter of the melted snow samples was analyzed by scanning electron microscopy with energy dispersive X-ray spectrometry (SEM-EDS) and by inductively coupled plasma mass spectrometry (ICP-MS). These analyses confirmed the presence of Saharan dust particle components in all areas with similar percentages, supported also by the positive correlations between Mg-Ca, Al-Ca, Al-Mg, and Al-K in all samples.

Financial system loss as an example of high consequence, high frequency events

Energy Technology Data Exchange (ETDEWEB)

McGovern, D.E.

1996-07-01

Much work has been devoted to high consequence events with low frequency of occurrence. Characteristic of these events are bridge failure (such as that of the Tacoma Narrows), building failure (such as the collapse of a walkway at a Kansas City hotel), or compromise of a major chemical containment system (such as at Bhopal, India). Such events, although rare, have an extreme personal, societal, and financial impact. An interesting variation is demonstrated by financial losses due to fraud and abuse in the money management system. The impact can be huge, entailing very high aggregate costs, but these are a result of the contribution of many small attacks and not the result of a single (or few) massive events. Public awareness is raised through publicized events such as the junk bond fraud perpetrated by Milikin or gross mismanagement in the failure of the Barings Bank through unsupervised trading activities by Leeson in Singapore. These event,s although seemingly large (financial losses may be on the order of several billion dollars), are but small contributors to the estimated $114 billion loss to all types of financial fraud in 1993. This paper explores the magnitude of financial system losses and identifies new areas for analysis of high consequence events including the potential effect of malevolent intent.

Othman, Jamal; Sahani, Mazrura; Mahmud, Mastura; Ahmad, Md Khadzir Sheikh

2014-06-01

This study assessed the economic value of health impacts of transboundary smoke haze pollution in Kuala Lumpur and adjacent areas in the state of Selangor, Malaysia. Daily inpatient data from 2005, 2006, 2008, and 2009 for 14 haze-related illnesses were collected from four hospitals. On average, there were 19 hazy days each year during which the air pollution levels were within the Lower Moderate to Hazardous categories. No seasonal variation in inpatient cases was observed. A smoke haze occurrence was associated with an increase in inpatient cases by 2.4 per 10,000 populations each year, representing an increase of 31 percent from normal days. The average annual economic loss due to the inpatient health impact of haze was valued at MYR273,000 ($91,000 USD). Copyright © 2014 Elsevier Ltd. All rights reserved.

2010-12-01

The US and Mexico share a common air basin along the ~200 km border between California and Baja California. The economical activities in this region are heavily influenced by the international trade and commerce between Mexico and the US that mainly occurs through the borders of the sister cities of San Diego-Tijuana and Calexico-Mexicali. The diversity and differences in the characteristics of emissions sources of air pollutants in the California-Mexico border region make this an important area for the study of the chemistry and trans-boundary transport of air pollutants. During May-June of 2010, the Cal-Mex 2010 field campaign included a series of measurements aimed at characterizing the emissions from major sources in the California-Mexico border region and assessing the possible impacts of these emissions on local and regional air quality. In this work we will present the results of the use of the Comprehensive Air quality model with extensions (CAMx) in a modeling domain that includes the sister cities of San Diego-Tijuana and Calexico-Mexicali for studying events of trans-boundary transport of air pollutants during Cal-Mex 2010. The measurements obtained during the Cal-Mex 2010 field campaign are used in the evaluation of the model performance and in the design of air quality improvement policies in the California-Mexico border region.

Transboundary aquifers: the response of international law and legal voids in Central America; Acuiferos transfronterizos: respuestas desde el derecho internacional y vacios en Centroamerica

Central America is one of the regions of the world that will suffer the impact of climate change much more than others. The adoption of clear rules on the use of transboundary aquifers and on the need to preserve these groundwater reservoirs from serious pollution by the various states in the region is absolutely essential. Despite the lack of any bilateral or regional frameworks to rule on this issue, many general regulations have been adopted within the international framework of the United Nations that are applicable to shared surface and groundwater resources as well as to transboundary aquifers. The case of the Las Crucitas project in Costa Rica, halted by domestic tribunals thanks to the decisive action of its civilian society, reflects a clear lack of technical information concerning aquifers in Costa Rica, and probably in many other states in the region, despite the very valuable efforts being undertaken by the OAS and UNESCO under the aegis of the ISARM project for the Latin American region.

Integrating EO data for applying the Nexus of water, energy and agriculture to monitor SDG Indicators within transboundary river basins

Zalidis, G.; Kavvada, A.; Crisman, T.

The NEXUS of water, energy and agriculture is widely recognized as an integrated approach for innovative management solutions and actions to protect natural resources. Soil Spectral Libraries (SSL) implement the NEXUS approach by combining Earth Observation (EO) and Geospatial Information (GI) data and tools to extract information on soil attributes rapidly, reliably and cost effectively. NEXUS approach for soil resources at large scales- across landscapes or regions- remains a challenge however, especially for stakeholders, and in regards to promoting the concept, disseminating the methodology, and discussing potential benefits at both local and transboundary river basin levels. The CEOS Data Cube is an excellent tool for collecting, processing and disseminating EO data, and providing `Analysis Ready Data' utilized both as a management tool for policy makers, and a tool boosting economic activity and supporting end-users. Thus, it helps supporting the tracking of, and reporting on, the Sustainable Development Goals (SDGs), and promoting targeted approaches to address specific SDG Indicators. Although several European projects in the Balkan transboundary river basin areas focus on existing/potential ties to specific SDG Indicators under the leadership of i-BEC, data are lacking for some regions, and there is an exigent need for country/region - specific case studies. A case study in Albania, the 3rd for CEOS and the 1st for Europe, will seek to build synergies between different sectors and activities (water, energy, food) and natural resources, while also accounting for ecosystem climate- regulating functions. This will contribute to the global expansion of the Data Cube initiative, while adding high quality datasets in GEOSS. Engagement of EO ecosystem stakeholders, together with National Statistical Offices, regionally and globally, should exploit the networking capacities of multipliers, maximizing the impact and reach of SSL.

Interestingly, both milestones followed the initial work of Max Theiler (son of Sir Arnold with yellow fever virus.

Spirulina as a livestock supplement and animal feed.

Science.gov (United States)

Holman, B W B; Malau-Aduli, A E O

2013-08-01

Spirulina (Athrospira sp.) is an edible microalga and a highly nutritious potential feed resource for many agriculturally important animal species. Research findings have associated Spirulina to improvements in animal growth, fertility, aesthetic and nutritional product quality. Spirulina intake has also been linked to an improvement in animal health and welfare. Its influence over animal development stems from its nutritive and protein-rich composition, thus leading to an increased commercial production to meet consumer demand. Consequently, Spirulina is emerging as a cost-effective means of improving animal productivity for a sustainable and viable food security future. However, our present knowledge of animal response to dietary Spirulina supplementation is relatively scanty and largely unknown. Therefore, the primary objective of this paper was to review past and current findings on the utilisation of Spirulina as a feed supplement and its impact on animal productivity and health. Only animals deemed to be of agricultural significance were investigated; hence, only ruminants, poultry, swine and rabbits and their responses to dietary Spirulina supplementation are covered. © 2012 Blackwell Verlag GmbH.

FAO/IAEA international symposium on sustainable improvement of animal production and health. Synopses

International Nuclear Information System (INIS)

2009-01-01

The on-going 'Livestock Revolution', a demand-driven increase in livestock production, especially in developing countries, presents both opportunities and risks. The shift in the human diet from plant-based protein sources to animal-based protein sources, consumer demand for safe and quality animal products, and expanding markets for livestock products have raised several challenges such as; cost-effective production of safe and quality animal products, control of emerging and zoonotic diseases, and efficient management of impact of livestock on the environment. However, these changes have also provided many opportunities to benefit the local economy and producers, and reduce poverty. New challenges and opportunities demand innovative ideas and approaches, and mechanisms to take this knowledge to potential users. Many of the approaches will be multidisciplinary in nature and require collaboration with specialists in areas other than animal scientists. Livestock production in developing countries is constrained by low genetic potential of animals, poor nutrition, poor husbandry and infectious diseases. Nuclear techniques, when applied in conjunction with conventional methods, can identify critical points in these areas that can be targeted for cost-effective improvements and interventions. Thus the challenge is to use such technologies to enhance food security and alleviate poverty by supporting sustainable livestock production systems in developing countries through strategic and applied research, technology transfer and capacity building. Topics addressed at the symposium: - Interactions among nutrition, reproduction and genotype; - Livestock-environment interaction / productivity/ climate (water/ land/ plants/heat/ altitude); - Detection and control of transboundary animal diseases, including zoonoses; - Animal product safety and food quality. Each of the papers published in this book of synopses has been indexed separately

Currently, there are no reports in the literature demonstrating any animal model that ingests one of the fattiest animal food source, the bovine brain. We hypothesized that a high-fat diet (HFD), based on dried bovine brain, could be used to develop an animal model possessing a spectrum of insulin resistance-related features. The HFD was formulated with 40% dried bovine brain plus 16.4% butter fat, prepared in-house. Furthermore, the diet contained 52% calories as fat and 73% of total fatty acids were saturated. Swiss mice weighing about 40 g were assigned to two dietary groups (n=6/group), one group received a standard chow diet and the other was given HFD for 3 months. The body weight and biochemical parameters of the animals were measured initially and at monthly intervals until the end of the experiment. Animals fed on a HFD showed a significant increase in the body and adipose tissue weight, serum total cholesterol and triglyceride levels, when compared with mice fed on the control diet. Additionally, the HFD group showed higher circulating levels of liver transaminases, such as alanine aminotransferase and aspartate aminotransferase, compared with the control group. Finally, to illustrate the usefulness of this model, we report that the HFD induced mild hyperglycemia, fasting hyperinsulinemia, and increased the homeostasis model of assessment (HOMA-IR), in comparison with the control group. In conclusion, our results show that HFD, based on dried bovine brain, causes insulin resistance-related metabolic disturbances. Thus, this may be a suitable model to study disturbances in energy metabolism and their consequences.

The radionuclides of most concern with respect to contamination of animals after a nuclear accident are radioiodine, radiocaesium and radiostrontium (ICRP 30, 1979). Of the other significant anthropogenic radionuclides likely to be released in most accidents, only small proportions of that ingested will be absorbed in an animals gut, and the main animal products, milk and meat, will not normally be contaminated to a significant extent. Animal products will mostly be contaminated as a result of ingestion of contaminated feed and possibly, but to a much lesser extent, from inhalation (for radioiodine only). Direct external contamination of animals is of little or no consequence in human food production. Radioiodine and radiostrontium are important with respect to contamination of milk; radiocaesium contaminates both milk and meat. The physical and chemical form of a radionuclide can influence its absorption in the animal gut. For example, following the Chernobyl accident radiocaesium incorporated into vegetation by root uptake was more readily absorbed than that associated with the original deposit. The transfer of radiocaesium and radiostrontium to animals will be presented both as transfer coefficients and aggregated transfer coefficients. For most animal meat products, only radiocaesium is important as other radionuclides do not significantly contaminate muscle. Farm animal products are the most important foodstuff determining radiocaesium intake by the average consumer in the Nordic countries. The major potential source of radioiodine and radiostrontium to humans is milk and milk products. Of the different species, the smaller animals have the highest transfer of radiocaesium from fodder to meat and milk. (EG). 68 refs.

In companion animal practice, convenience euthanasia (euthanasia of a physically and psychologically healthy animal) is recognized as one of the most difficult situations. There is little published on veterinary perceptions of the consequences of convenience euthanasia. A qualitative study on the subject based on interviews with 14 veterinarians was undertaken. The animal's interests in the dilemma of convenience euthanasia was taken into consideration, strictly from the point of view of the physical suffering and stress related to the procedure. The veterinarian's goal was to respect the animal's interests by controlling physical pain. Most often, veterinarians made their own interests and those of the owners a priority when considering the consequences of their decision to perform or refuse convenience euthanasia.

The investigation was performed in 3 groups under different conditions of exposure of the population: (i) among the people of Russia and Belorussia exposed due to the Chernobyl accident, (ii) among the people living on the Tetscha river basing in the South Urals; (iii) among the occupational contingent of 'Mayak' and the members of their families; The experimental estimation of genetic consequences was made on the offsprings of the white male rats. The male rats were irradiated daily for 10-15 days with external gamma- radiation of different dose power. The range of the doses received by the animals was approximated to the conditions of the exposure of man to the interval from 4 to 79 cSv for a year. (author)

Contrasting Attitudes towards Animal Welfare Issues within the Food Chain

Directory of Open Access Journals (Sweden)

Ada Braghieri

2013-06-01

Full Text Available Intensive systems have facilitated the production of animal-based products at relatively low prices. On one hand, these methods have been increasingly considered to be responsible for a dramatic reduction in animal welfare, as indicated by the high prevalence of stereotypies in sows, brittle bones in hens, lameness in broilers and short life span in dairy cattle. As a consequence, large segments of animal welfare-sensitive consumers have been identified. On the other hand, price conscious consumers, if accepting higher prices, are more likely to require explicit justification of returns in quality. Therefore, scientifically validated monitoring systems for assessing the welfare of farm animals have been developed in order to provide a certification system, allow the differentiation of animal-based products through constant and reliable signaling systems, and promote animal welfare friendly farming systems.

Morally relevant differences between animals and human beings justifying the use of animals in biomedical research.

Science.gov (United States)

Dennis, J U

1997-03-01

I have attempted to show that the differential qualities of animals and human beings indeed to have bearing on moral rules and the derivation of rights, including rights established on the basis of reason and utilitarianism. Special rights for members of our species are not simply a consequence of human domination and self-interest. I also have tried to show that rights arise from values and that the qualities we value most highly often are the ones that distinguish human beings from other species. I maintain that giving more value to human lives over animal lives achieves reflective balance with the commonsense notions that most of us have developed. Because utilitarianism, contractualism, and the classical philosophical methods of Kant and Aristotle all may allow favoring human interests over animal interests, it seems reasonable to suspect that animal rights activists embrace narrow, extremist views. There are many uniquely human experiences to which we ascribe high value-deep interpersonal relationships, achieving a life's goal, enjoying a complex cultural event such as a play or an opera, or authoring a manuscript. Therefore, it would seem improper that social and ethical considerations regarding animals be centered entirely on the notion of a biological continuum, because there are many kinds of human experience-moral, religious, aesthetic, and otherwise-that appear to be outside the realm of biology. Knowledge about the biology of animals is helpful for making moral decisions about our obligations to them. Why, then, is there a substantial population of animal rights activists in Europe, the United States, and throughout the world, who would not agree with my conclusions? Certain habitual ways of thinking may encourage anthropomorphism and equating animal interests with human interests. Certain metaphysical beliefs, such as a belief in reincarnation, also might favor animal rights. It also is possible that a number of people are being deceived and misled by

Inter-annual variability of air mass and acidified pollutants transboundary exchange in the north-eastern part of the EANET region

Anthropogenic emissions, be it exhaust gases or aerosols, stem from multitude of sources and may survive long-range transport within the air masses they were emitted into. So they follow regional and global transport pathways varying under different climatological regimes. Transboundary transfer of pollutants occurs this way and has a significant impact on the ecological situation of the territories neighbouring those of emission sources, as found in a few earlier studies examining the environmental monitoring data [1]. In this study, we employ a relatively facile though robust technique for estimating the transboundary air and concomitant pollutant fluxes using actual or climatological meteorological and air pollution monitoring data. Practically, we assume pollutant transfer being proportional to the horizontal transport of air enclosed in the lower troposphere and to the concentration of the pollutant of interest. The horizontal transport, in turn, is estimated using the mean layer wind direction and strength, or their descriptive statistics at the individual transects of the boundary of interest. The domain of our interest is the segment of Russian continental border in East Asia spanning from 88° E (southern Middle Siberia) to 135° E (Far East at Pacific shore). The data on atmospheric pollutants concentration are available from the Russian monitoring sites of the region-wide Acid Deposition Monitoring Network in East Asia (EANET, http://www.eanet.asia/) Mondy (Baikal area) and Primorskaya (near Vladivostok). The data comprises multi-year continuous measurement of gas-phase and particulate species abundances in air with at least biweekly sampling rate starting from 2000. In the first phase of our study, we used climatological dataset on winds derived from the aerological soundings at Russian stations along the continental border for the 10-year period (1961-1970) by the Research Institute of Hydrometeorological Information - World Data Centre (RIHMI-WDC) [3

The rights of man and animal experimentation.

OpenAIRE

Martin, J

1990-01-01

Since emotions give contradictory signals about animal experimentation in medical science, man's relationship to animals must be based upon reason. Thomas Aquinas argues that man is essentially different from animals because man's intellectual processes show evidence of an abstract mechanism not possessed by animals. Man's rights arise in association with this essential difference. The consequence is that only man possesses true rights by Aquinas's definition; animals have them only by analog...

The purpose of the border air quality study, under the Canada-United States (US) international airshed strategy, was to assess the transboundary transport of air pollutants between the US and Canada. This report presented an analysis of pollutants in ambient air and assessed their most likely source location and transport direction. The pollutants of most interest were fine particulate matter (PM 2.5 ) and ground-level ozone (O 3 ) due to their association with human health effects. The data analyzed in this report represent just under two years of meteorological, air quality, and traffic volume data. Data was collected at the Osoyoos Canada customs site from November 2004 to September 2006. Osoyoos is located at the southern Canadian extreme of the Okanagan Valley in British Columbia. The report provided data summaries and discussed meteorology and elevated concentration conditions of PM 2.5 ; O 3 ; nitric oxide (NO); nitrogen; and sulphur dioxide (SO 2 ). Next, the report provided a multi-pollutant analysis as well as an episode analysis consisting of 4 case studies. The report also included an analysis of transboundary pollutant transport such as a wind sector analysis of pollutant concentration and comparison with modeled transport. Last, the report provided a summary and a discussion of policy implications. It was concluded that US-Canada transboundary transport of pollutants occurs through the Okanagan Valley in which the Osoyoos Canada Customs border air quality station is located. The study recommended further investigation of air parcel trajectories and synoptic-scale conditions leading to elevated O 3 concentrations, as well as the collection of at least 3 full years worth of PM 2.5 and O 3 data to calculate and measure against Canada-wide standards/US national ambient air quality objectives. refs., tabs., figs

The northeastern China frequently experiences severe aerosol pollution in winter under unfavorable meteorological conditions. How and to what extent the meteorological factors affect the air quality there are not yet clearly understood. Thus, this study investigated the impacts of synoptic patterns on the aerosol transport and planetary boundary layer (PBL) structure in Shenyang from 1 to 3 December 2016, using surface observations, sounding measurements, satellite data, and three-dimensional simulations. Results showed that the aerosol pollution occurred in Shenyang was not only related to the local emissions, but also contributed by trans-boundary transport of aerosols from the Beiijng-Tianjin-Hebei (BTH) region. In the presence of the westerly and southwesterly synoptic winds, the aerosols emitted from BTH could be brought to Shenyang. From December 2 to 3, the aerosols emitted from BTH accounted for ∼20% of near-surface PM2.5 in Shenyang. In addition, the large-scale synoptic forcings could affect the vertical mixing of pollutants through modulating the PBL structure in Shenyang. The westerly and southwesterly synoptic winds not only brought the aerosols but also the warmer air masses from the southwest regions to Shenyang. The strong warm advections above PBL could enhance the already existing thermal inversion layers capping over PBL in Shenyang, leading to the suppressions of PBL. Both the trans-boundary transport of aerosols and the suppressions of PBL caused by the large-scale synoptic forcings should be partly responsible for the poor air quality in Shenyang, in addition to the high pollutant emissions. The present study revealed the physical mechanisms underlying the aerosol pollution in Shenyang, which has important implications for better forecasting and controlling the aerosols pollution.

Full Text Available For the most effective and efficient management of certain natural resources (e.g. protected areas and disasters (e.g. wildfires transboundary approaches are needed. In addition in the management of protected areas, the role of wildfire should be incorporated, something that was ignored in the past and led to catastrophic wildfires. The Black Sea is a region that wildfires in the protected areas are expected to increase. This has to do with the abandonment of rural areas and the higher temperatures, especially during summer, due to climate change. Interesting is also the fact that some countries of the region have extensive experience while other do not have neither the experience nor the necessary infrastructures to face large wildfires. A transboundary collaboration would be very beneficial to the countries with limited experiences and capacities to suppress wildfires. The objective of this study is to be proactive by developing innovative tools to help suppress wildfires and enhancing the knowledge on wildfires and protected areas. The innovative tools included 4 different research activities and products. Firstly, an online Digital Geodatabase for the six pilot areas was developed. Next forest fire fuels and maps were developed while a forest fire behavior model was run to create the overall fire risk maps for the pilot areas. To estimate water resources and watershed streamflows the hydrologic model SWAT was validated and calibrated for the pilot areas. The final activities included a multi-criteria decision analysis to select the optimal location of the water reservoirs and the use of spatial analyst to provide the optimal routes to reach reservoirs by the fire vehicles. To enhance the responsible agency personnel along with stakeholders knowledge of the region, a Neighborhood Network with regular quarterly meetings was established. Participants for all six project countries were present in the meetings. Overall, new tool that will enhance

International Direct Investment and Transboundary Pollution: An Empirical Analysis of Complex Networks

Full Text Available Using complex networks and spatial econometric methods, we empirically test the extent to which a country’s influence and its position in an international investment network affect environmental quality as well as the country’s role in transboundary pollution transfer. The estimated results show that the ties connecting nodes together in an international investment network have significant impacts on global environmental pollution. Additionally, node linkages between developing countries have stronger negative effects on environmental quality than node linkages between developed countries. Moreover, greater node importance and node centrality accelerate the speed and scale of the growth of polluting industries, which allows developed countries to more easily transfer their pollution-intensive industries to developing countries that possess higher node dependency. We also find that the factor endowment effect coexists with the pollution haven effect, the effects of environmental regulation advantage in the international investment network are greater than the impact of factor endowment advantage.

The atmospheric models can be used to simulate the transport of contaminants in typical accidental cases and for realistic meteorological conditions. Some numerical models for weather forecast can be used for near to real simulations of propagation of radioactive nuclides or classical chemical pollutants to the atmosphere. The various meteorological parameters are taken into account and various meteorological conditions, even complex ones, can be analyzed. The models can be used for very well assessment of the airborne pollution from energy sources and industrial installations, for comparative studies and for safety analysis. This report describes an proposal for a project of the transboundary pollution simulation, that can be used for the East Mediterranean Region. The project is based on the numerical models developed in the in simulating of the Chernobyl accident and similar hypothetical cases. The study is based on an atmospheric models developed in Euro-Mediterranean Centre on Insular Coastal Dynamics (ICoD), Foundation for International Studies, Valeta, Malta

During the recent years, in vivo imaging of small animals using SPECT has become of growing relevance. Along with the development of dedicated high-resolution small animal SPECT cameras, an increasing number of conventional clinical scanners has been equipped with single or multipinhole collimators. This paper reviews the small animal tomographs, which are operating at present and compares their performance characteristics. Furthermore, we describe the in vivo imaging studies, which have been performed so far with the individual scanners and survey current approaches to optimize molecular imaging with small animal SPECT.

Consequences of the exposure at low dose rates-contribution of animal experimentation

International Nuclear Information System (INIS)

Masse, R.

1990-01-01

The exposure of laboratory animals to the various types of radiations will induce cancers in relation with the tissue absorbed doses. The shape of the dose-effet relationship is most variable. It is important to distinguish which tumours are comparable to human tumours. Those showing more analogies answer but seldom to the classical lineo-quadratic relationship; however, a strong attenuation of induction is demonstrated at low dose rates. Quasi-threshold relationships are seen after the exposure of some tissues to high-LET radiations. These observations question the validity of generalizing the radiobiologists' dual action theory, setting the origin of the dose-effect relationship in the induction of events within the DNA molecule. There is an alternative in the cellular collaboration events; it assumes that the effectiveness per dose unit decreases constantly as an inverse function of the dose rate [fr

The aim of this paper is to examine how the river flow monitoring consists a tool for hydro-diplomacy. Management of transboundary catchments and the demand of common water resources, often comprise the cause of conflicts and tension threatening the peaceful coexistence of nations. The Water Framework Directive 2000/60/EU sets a base for water management contributing to common approaches, common goals, common principles as well as providing new definitions and measures for Europe's water resources. In northern Greece the main renewable resources are "imported" (over 25% of its water reserves) and for this reason the implementation of continuous flow measurements throughout the year is necessary, even though difficult to achieve. This paper focuses on the three largest transboundary rivers in Northern Greece. Axios and Strymonas river flow across the region of Central Macedonia in Northern Greece. Axios flows from FYROM to Greece, and Strymonas from Bulgaria to Greece. Nestos river flows from Bulgaria to Greece. The Greek part is in the region of Eastern Macedonia and Thrace in Northern Greece. Significant productive agricultural areas around these rivers are irrigated from them so they are very important for the local society. Measurements of the river flow velocity and the flow depth have been made at bridges. The frequency of the measurements is roughly monthly, because it is expected a significant change in the depth flow and discharge. A series of continuously flow measure-ments were performed during 2013 and 2014 using flowmeters (Valeport and OTT type). The cross-section characteristics, the river flow velocity of segments and the mean water flow velocity and discharge total profile were measured and calculated re-spectively. Measurements are conducted in the framework of the national water resources monitoring network, which is realised in compliance to the Water Framework Directive under the supervision and coordination of the Hellenic Ministry for the

Demand for animal protein for human consumption is rising globally at an unprecedented rate. Modern animal production practices are associated with regular use of antimicrobials, potentially increasing selection pressure on bacteria to become resistant. Despite the significant potential consequences for antimicrobial resistance, there has been no quantitative measurement of global antimicrobial consumption by livestock. We address this gap by using Bayesian statistical models combining maps of livestock densities, economic projections of demand for meat products, and current estimates of antimicrobial consumption in high-income countries to map antimicrobial use in food animals for 2010 and 2030. We estimate that the global average annual consumption of antimicrobials per kilogram of animal produced was 45 mg⋅kg−1, 148 mg⋅kg−1, and 172 mg⋅kg−1 for cattle, chicken, and pigs, respectively. Starting from this baseline, we estimate that between 2010 and 2030, the global consumption of antimicrobials will increase by 67%, from 63,151 ± 1,560 tons to 105,596 ± 3,605 tons. Up to a third of the increase in consumption in livestock between 2010 and 2030 is imputable to shifting production practices in middle-income countries where extensive farming systems will be replaced by large-scale intensive farming operations that routinely use antimicrobials in subtherapeutic doses. For Brazil, Russia, India, China, and South Africa, the increase in antimicrobial consumption will be 99%, up to seven times the projected population growth in this group of countries. Better understanding of the consequences of the uninhibited growth in veterinary antimicrobial consumption is needed to assess its potential effects on animal and human health. PMID:25792457

Studies of persistent organic pollutants (POPs) in the Russian Arctic were conducted recently by a Arctic Monitoring and Assessment Program (AMAP) project. This project developed new data on the POPs pollution levels in the environment and biosphere, including PCBs and PCDD/Fs, in arctic regions of Russia. Transboundary transport and biomagnification within food chains in arctic regions result in POPs accumulation in tissues of fish and marine animals. The aim of this study was to determine the concentration of indicator PCBs, co-planar PCBs and PCDD/Fs in different tissues and organs of seals, walruses and whales caught near the seashore of Chukotski Peninsula (settlement of Lavrenty), Russia, to determine the background level of arctic biota pollution and to study distribution of toxicants in organisms of marine animals. Sampling was made in the course of the 1{sup st} and the 2{sup nd} stages of the 4{sup th} phase of Raipon/AMAP/GEF project ''Persistent Toxic Substances (PTS), Food Security and Indigenous Peoples of the Russian North'' in 2002 by researchers of the Regional Center for Monitoring of the Arctic (RCMA), St. Petersburg, Russia.

Six high-level evernimicin-resistant Enterococcus faecium isolates were identified among 304 avilarnycin-resistant E. faecium isolates from animals and 404 stool samples from humans with diarrhea. All four animal isolates, and one of the human isolates, were able to transfer resistance...... to a susceptible E. faecium strain. The resulting transconjugants all tested positive for the presence of emtA, a gene encoding a methyltransferase previously linked with high-level evernimicin resistance. The four transconjugants derived from animal isolates all carried the same plasmid, while a differently sized...... plasmid was found in the isolate from humans. This study demonstrated a low incidence of high-level evernimicin resistance mediated by the emtA gene in different E. faecium isolates of animal and human origin....

Transboundary air pollution is a global environmental and public health problem including in the U.S., where pollution emissions from China, the largest emitter of anthropogenic air pollution in the world, can travel across the Pacific Ocean and reach places like California and Oregon. We examine the effects of transboundary air pollution following major events in China, specifically sandstorms, a natural-occurring source of air pollution, and Chinese New Year, a major 7-day holiday, on background air quality in the U.S. We focus on high elevation sites on the west coast between 2000 and 2013. We use regression analysis and a natural experiment to exploit the variation in the timing of these events in China, which are plausibly uncorrelated to other factors that affect air quality in China and the U.S. We find that sandstorms are associated with statistically significant increases in background coarse and fine particulate matter (PM) in the U.S., representing between 16 and 39% of average weekly PM levels. We also find Chinese New Year is associated with modest reductions in background air quality in the U.S., representing between 0.4 and 2.5% of PM levels. Findings are robust to different models and falsification tests. These results suggest that regression analysis could be a powerful tool to complement other, more widely used techniques in the environmental sciences that study this problem. This also has important implications for policymakers, who could track major sandstorms in China and prepare for possible increased foreign pollution emissions in the U.S. Copyright © 2018 Elsevier Ltd.

Pollutants that are usually transported from southern Asia to the Tibetan Plateau deposit on the Plateau surface, change snow albedo and thereby surface radiative flux. This results numerous climatic implications like as erratic monsoon, perturbation in hydrological cycle, etc. However, the accurate estimation of these climatic implications is not well understood, because the atmospheric pollution is a heterogeneous mixture of various particle types. Therefore, this part of climate research requires a detailed investigation of physical and chemical properties of atmospheric pollutants. This study aimed to examine the physical and chemical properties of atmospheric pollutants across the Himalayan regions along two transboundary south-north transects. The information of individual-particles was obtained using microscopy-based techniques that comprises transmission electron microscope (TEM) and Energy-dispersive X-ray spectrometer (EDX). Study capture the signatures of various types of atmospheric species such as black carbon (BC), mineral dust, fly ash, organic matter, sulfate, nitrite, ammonium, and NaCl. Microscopy-based techniques confirm that these particles were generally in mixing state, for example salt-coated particles accounting for 25-56% of the total particles in sampled locations. Our analysis shows that urban and rural locations are characterized with atmospheric particles which sourced from anthropogenic activities, whereas remote locations with those released from natural crustal. However, the relative contributions of anthropogenic particles were higher than that of particles released from natural crustal. The presence of such particles over remote locations of Himalayan region provides an evidence of prevailing atmospheric transport processes, which further need to be well understood. It is expected that this work would be helpful in understanding the regional atmospheric conditions and the transboundary transport process of haze particles. As these

Marine Spatial Planning in a Transboundary Context: Linking Baja California with California's Network of Marine Protected Areas

2017-05-01

Full Text Available It is acknowledged that an effective path to globally protect marine ecosystems is through the establishment of eco-regional scale networks of MPAs spanning across national frontiers. In this work we aimed to plan for regionally feasible networks of MPAs that can be ecologically linked with an existing one in a transboundary context. We illustrate our exercise in the Ensenadian eco-region, a shared marine ecosystem between the south of California, United States of America (USA, and the north of Baja California, Mexico; where conservation actions differ across the border. In the USA, California recently established a network of MPAs through the Marine Life Protection Act (MLPA, while in Mexico: Baja California lacks a network of MPAs or a marine spatial planning effort to establish it. We generated four different scenarios with Marxan by integrating different ecological, social, and management considerations (habitat representation, opportunity costs, habitat condition, and enforcement costs. To do so, we characterized and collected biophysical and socio-economic information for Baja California and developed novel approaches to quantify and incorporate some of these considerations. We were able to design feasible networks of MPAs in Baja California that are ecologically linked with California's network (met between 78.5 and 84.4% of the MLPA guidelines and that would represent a low cost for fishers and aquaculture investors. We found that when multiple considerations are integrated more priority areas for conservation emerge. For our region, human distribution presents a strong gradient from north to south and resulted to be an important factor for the spatial arrangement of the priority areas. This work shows how, despite the constraints of a data-poor area, the available conservation principles, mapping, and planning tools can still be used to generate spatial conservation plans in a transboundary context.

2014-06-01

The first generation of research on animal social networks was primarily aimed at introducing the concept of social networks to the fields of animal behaviour and behavioural ecology. More recently, a diverse body of evidence has shown that social fine structure matters on a broader scale than initially expected, affecting many key ecological and evolutionary processes. Here, we review this development. We discuss the effects of social network structure on evolutionary dynamics (genetic drift, fixation probabilities, and frequency-dependent selection) and social evolution (cooperation and between-individual behavioural differences). We discuss how social network structure can affect important coevolutionary processes (host-pathogen interactions and mutualisms) and population stability. We also discuss the potentially important, but poorly studied, role of social network structure on dispersal and invasion. Throughout, we highlight important areas for future research.

World Organisation for Animal Health: strengthening Veterinary Services for effective One Health collaboration.

Science.gov (United States)

Corning, S

2014-08-01

To effectively reduce health risks at the animal-human-ecosystems interface, a One Health strategy is crucially important to create strong national and regional animal health systems that are well coordinated with strong public health systems. Animal diseases, particularly those caused by new and emerging zoonotic pathogens, must be effectively controlled at their source to reduce their potentially devastating impact upon both animal and human health. As the international organisation responsible for developing standards, guidelines and recommendations for animal health, the World Organisation for Animal Health (OIE) plays an important role in minimising animal and public health risks attributable to zoonoses and other animal diseases, which can have severe consequences for global food safety and security. National Veterinary Services, which implement OIE animal health and welfare standards and other measures, are the first line of defence against these diseases, and must have the capacity to meet the core requirements necessary for their diagnosis and control. The OIE works collaboratively with the World Health Organization and Food and Agriculture Organization of the United Nations to improve the ability of national animal and public health systems to respond to current and emerging animal health risks with public health consequences. In addition to improving and aligning national laboratory capacities in high-risk areas, the OIE collaborates on One Health-oriented projects for key diseases, establishing model frameworks which can be applied to manage other existing and emerging priority diseases. This article reviews the role and activities of the OIE in strengthening the national Veterinary Services of its Member Countries for a more effective and sustainable One Health collaboration.

Robots and people with dementia: Unintended consequences and moral hazard.

Science.gov (United States)

O'Brolcháin, Fiachra

2017-01-01

The use of social robots in elder care is entering the mainstream as robots become more sophisticated and populations age. While there are many potential benefits to the use of social robots in care for the older people, there are ethical challenges as well. This article focuses on the societal consequences of the adoption of social robots in care for people with dementia. Making extensive use of Alasdair MacIntyre's Dependent Rational Animals to discuss issues of unintended consequences and moral hazard, we contend that in choosing to avoid the vulnerability and dependency of human existence, a society blinds itself from the animal reality of humankind. The consequence of this is that a flourishing society, in which each individual is helped to develop the virtues essential to her flourishing, becomes harder to achieve.

Defining a stable water isotope framework for isotope hydrology application in a large trans-boundary watershed (Russian Federation/Ukraine).

Vystavna, Yuliya; Diadin, Dmytro; Huneau, Frédéric

2018-05-01

Stable isotopes of hydrogen ( 2 H) and oxygen ( 18 O) of the water molecule were used to assess the relationship between precipitation, surface water and groundwater in a large Russia/Ukraine trans-boundary river basin. Precipitation was sampled from November 2013 to February 2015, and surface water and groundwater were sampled during high and low flow in 2014. A local meteoric water line was defined for the Ukrainian part of the basin. The isotopic seasonality in precipitation was evident with depletion in heavy isotopes in November-March and an enrichment in April-October, indicating continental and temperature effects. Surface water was enriched in stable water isotopes from upstream to downstream sites due to progressive evaporation. Stable water isotopes in groundwater indicated that recharge occurs mainly during winter and spring. A one-year data set is probably not sufficient to report the seasonality of groundwater recharge, but this survey can be used to identify the stable water isotopes framework in a weakly gauged basin for further hydrological and geochemical studies.

Livestock export is vital to the Somali economy. To protect Somali livestock exports from costly import bans used to control the international spread of disease, better certification of livestock health status is required. We performed quantitative risk assessment and cost-effectiveness analysis on different health certification protocols for Somali livestock exports for six transboundary diseases. Examining stock at regional markets alone without port inspection and quarantine was inexpensive but was ineffective for all but contagious bovine pleuropneumonia, contagious caprine pleuropneumonia and peste des petits ruminants. While extended pre-export quarantine improves detection of infections that cause clinical disease, if biosecurity is suboptimal quarantine provides an opportunity for transmission and increased risk. Clinical examination, laboratory screening and vaccination of animals for key diseases before entry to the quarantine station reduced the risk of an exported animal being infected. If vaccination could be reliably performed weeks before arrival at quarantine its effect would be greatly enhanced. The optimal certification method depends on the disease. Laboratory diagnostic testing was particularly important for detecting infections with limited clinical signs in male animals (only males are exported); for Rift Valley fever (RVF) the probability of detection was 99% or 0% with and without testing. Based on our findings animal inspection and certification at regional markets combined with quarantine inspection and certification would reduce the risk of exporting infected animals and enhance disease control at the regional level. This is especially so for key priority diseases, that is RVF, foot-and-mouth disease and Brucellosis. Increased data collection and testing should be applied at point of production and export.

The state of transboundary air pollution: 1989 update

International Nuclear Information System (INIS)

1990-01-01

This sixth volume of the series of Air Pollution Studies published under the auspices of the Executive Body for the Convention on Long-range Transboundary Air Pollution, contains the documents reviewed and approved for publication at the seventh session of the Executive Body held at Geneva from 21 to 24 November 1989. Part one is the annual review of strategies and policies for air pollution abatement. Country by country, recent legislative and regulatory developments are summarized, including ambient-air quality standards, fuel-quality standards, emission standards, as well as economic instruments for air pollution abatement. Part two is an executive summary of the 1988 forest damage survey in Europe, carried out under the International Co-operative Programme for Assessment and Monitoring of Air Pollution Effects on Forests which was established by the Executive Body for the Convention in 1985. A total of 25 countries participated in the survey, conducted in accordance with common guidelines laid down in an ECE manual on methodologies and criteria for harmonized sampling, assessment, monitoring and analysis of the effects of air pollution on forests. Parts three and four describe the effects of mercury and some other heavy metals related to the long-range atmospheric transport of pollution. The section on mercury describes the environmental effects and the causes of mercury pollution in air and atmospheric deposition, including its sources and its transport from forest soils into fresh water and aquatic organisms. The section dealing with other heavy metals (such as asbestos, cadmium and lead) describes the process of atmospheric transport and deposition, the effects on forest ecosystems, ground water, surface water and agricultural products.

Animals have been selected to improve their productivity in order to increase the profitability to the producer. In this scenario, not much attention was given to health traits. As a consequence of that, selection was made for animals with higher production and a shortened productive life. In addition to that, the intense production system used in livestock has forced animals to be exposed to higher pathogen loads, therefore predisposing them to infections. Infectious diseases are known to be caused by micro-organisms that are able to infect and colonize the host, affecting their physiological functions and causing problems in their production and on animal welfare. Even with the best management practices, diseases are still the most important cause of economic losses in the animal industry. In this review article we have addressed the new tools that could be used to select animals to better cope with diseases and pathogens.

Global situational awareness and early warning of high-consequence climate change.

Global monitoring systems that have high spatial and temporal resolution, with long observational baselines, are needed to provide situational awareness of the Earth's climate system. Continuous monitoring is required for early warning of high-consequence climate change and to help anticipate and minimize the threat. Global climate has changed abruptly in the past and will almost certainly do so again, even in the absence of anthropogenic interference. It is possible that the Earth's climate could change dramatically and suddenly within a few years. An unexpected loss of climate stability would be equivalent to the failure of an engineered system on a grand scale, and would affect billions of people by causing agricultural, economic, and environmental collapses that would cascade throughout the world. The probability of such an abrupt change happening in the near future may be small, but it is nonzero. Because the consequences would be catastrophic, we argue that the problem should be treated with science-informed engineering conservatism, which focuses on various ways a system can fail and emphasizes inspection and early detection. Such an approach will require high-fidelity continuous global monitoring, informed by scientific modeling.

Europe’s Wild Heart – still beating? Experiences from a new transboundary wilderness area in the middle of the Old Continent

2013-03-01

Full Text Available The face of Europe has been shaped by human civilization for centuries and wilderness did not only vanish from the continent’s surface but also from humans’ minds and experiences. However, there are still a few places left, which have remained more or less unmodified and have at least the potential for rewilding. Among them are the Šumava National Park and the neighbouring Bavarian Forest NP, which together create a unique forest zone in the middle of Europe susceptible to host and demonstrate natural forest dynamics and ecosystem processes. This is also a large and very important Natura 2000 area. Transboundary cooperation between both National parks has improved since 1990, when the former Iron Curtain Corridor was opened, and culminated by the project Europe’s Wild Heart. The main goal of the project Europe’s Wild Heart, which started in 2008, was to develop a transboundary wilderness area in the core zones of the two national parks – BFNP and ŠNP. The project area was 13,060 ha and a “life story” of this project is described in this paper. A common “vision 2020” was signed where both parks committed among other things “to achieve a joint core area of about 15,000 ha with harmonized management principles, information services and monitoring networks to officially become the first and largest transboundary wilderness area in Central Europe”. Unfortunately, the bark beetle outbreak which followed the Kyrill hurricane in 2008 and 2009 escalated the discussion about appropriate forest management in the ŠNP. Opponents of the national park principles, non-intervention and wilderness concept became more and more vocal. The situation escalated after the election in 2010 when the Green Party was replaced by conservatives (ODS – Civic Democratic Party at the Czech Ministry of Environment. Clear cuttings were started in some former non-intervention parts of the ŠNP and hunting was again allowed in the core zone. Since then

Laboratory animal: biological reagent or living being?

The duties of humans toward non-human animals and their rights in society have been debated for a long time. However, a discussion on the terminology used for the identification of laboratory animals is usually not considered, although the employment of inadequate terminology may generate disastrous consequences for the animals before, during, and after the experiment. This study intends to defend the use of appropriate terminology, call attention to an unethical attitude of certain professionals when dealing with experimental animals, and also propose operational mechanisms, which allow for those distortions to be corrected.

Mycotoxins have the potential to enter the human food chain through carry-over of contaminants from feed into animal-derived products. The objective of the study was to develop a reliable and sensitive method for the analysis of 30 mycotoxins in animal feed and animal-derived food (meat, edible animal tissues, and milk) using liquid chromatography-tandem mass spectrometry (LC-MS/MS). In the study, three extraction procedures, as well as various cleanup procedures, were evaluated to select the most suitable sample preparation procedure for different sample matrices. In addition, timed and highly selective reaction monitoring on LC-MS/MS was used to filter out isobaric matrix interferences. The performance characteristics (linearity, sensitivity, recovery, precision, and specificity) of the method were determined according to Commission Decision 2002/657/EC and 401/2006/EC. The established method was successfully applied to screening of mycotoxins in animal feed and animal-derived food. The results indicated that mycotoxin contamination in feed directly influenced the presence of mycotoxin in animal-derived food.

Full Text Available For centuries morbillivirus infections have had a huge impact on both human beings and animals. Morbilliviruses are highly contagious pathogens that cause some of the most devastating viral diseases of humans and animals world wide. They include measles virus (MV, canine distemper virus (CDV, rinderpest virus (RPV and peste des petits ruminants (PPRV virus. Furthermore, new emerging infectious diseases of morbilliviruses with significant ecological consequences of marine mammals have been discovered in the past decades. Phocid distemper virus (PDV in seals and the cetacean morbillivirus (CMV have been found in dolphins, whales and porpoises. Peste des petits ruminants (PPR is a highly contagious ,infectious , an acute or sub acute viral disease of domestic and wild small ruminants characterized by fever, oculonasal discharges, stomatitis, conjunctivitis, gastroenteritis and pneumonia. Goats are more severely affected than sheep. It is also known as pseudorinderpest of small ruminants, pest of small ruminants, pest of sheep and goats, kata, stomatitis- pneumoentritis syndrome, contagious pustular stomatitis and pneumoentritis complex. It is one of the major notifiable diseases of the World Organization for Animal Health (OIE. [Vet. World 2009; 2(4.000: 150-155

After Indonesia’s Ratification: The ASEAN Agreement on Transboundary Haze Pollution and Its Effectiveness As a Regional Environmental Governance Tool

Directory of Open Access Journals (Sweden)

Daniel Heilmann

2015-01-01

Full Text Available On 20 January 2015 Indonesia deposited its instrument of ratification for the ASEAN Agreement on Transboundary Haze Pollution with the ASEAN Secretariat, becoming the last ASEAN member state to join the treaty. Haze pollution poses a serious health threat to the people of Indonesia, Singapore and Malaysia, and for decades haze pollution has been a highly contentious issue among ASEAN member states. This article argues that Indonesia’s ratification will not be an immediate game changer. The mechanisms of the agreement are too weak to contribute much to a reduction of haze pollution in the region. The agreement is designed according to the ASEAN way: a non-binding approach that is based on the principles of state sovereignty and non-intervention. This makes it unlikely that the agreement itself will bring about change, even now that all ASEAN member states have ratified it.

Transboundary water pollution management
Lessons learned from river basin management in China, Europe and the Netherlands

Directory of Open Access Journals (Sweden)

Xia Yu

2011-01-01

Full Text Available Transboundary water pollution management is a challenge for China at this moment in time. By introducing relevant legal arrangements, we mainly discuss the competent authorities, the legal instruments and dispute settlement procedures concerning this issue in China. The experiences from international, EU and Dutch water law gives us a comparative perspective. As a conclusion, we agree that China has set up a basic legal system to solve the problem, but a greater effort can still be made, for instance including more public opinion, clearly defining the competent authorities, and enacting more legislation. At the same time, the Chinese experience, such as a new model for a monitoring system and a target responsibility system, also provides the rest of the world with a new approach.

A South African Perspective on a Possible Benefit-Sharing Approach for Transboundary Waters in the SADC Region

Directory of Open Access Journals (Sweden)

Anthony Turton

2008-10-01

Full Text Available The concept of benefit-sharing is emerging in the international discourse on transboundary water resource management with greater intensity than a decade ago. While it sounds simple, the concept is complex and benefits are difficult to quantify and thus the concept remains unconvincing to potentially sceptical negotiating partners. Any discourse on water resource management is based on a core logic. This paper tries to distil some elements of a proposed benefit-sharing approach, presenting an alternative core logic, showing how these differ from what can be thought of as the traditional paradigm. This work is linked to ongoing research at the South African Council for Scientific and Industrial Research (CSIR, into benefit-sharing and processes of policy harmonisation, within the context of developing countries.

Statistical surrogate models for prediction of high-consequence climate change.

Energy Technology Data Exchange (ETDEWEB)

Constantine, Paul; Field, Richard V., Jr.; Boslough, Mark Bruce Elrick

2011-09-01

In safety engineering, performance metrics are defined using probabilistic risk assessments focused on the low-probability, high-consequence tail of the distribution of possible events, as opposed to best estimates based on central tendencies. We frame the climate change problem and its associated risks in a similar manner. To properly explore the tails of the distribution requires extensive sampling, which is not possible with existing coupled atmospheric models due to the high computational cost of each simulation. We therefore propose the use of specialized statistical surrogate models (SSMs) for the purpose of exploring the probability law of various climate variables of interest. A SSM is different than a deterministic surrogate model in that it represents each climate variable of interest as a space/time random field. The SSM can be calibrated to available spatial and temporal data from existing climate databases, e.g., the Program for Climate Model Diagnosis and Intercomparison (PCMDI), or to a collection of outputs from a General Circulation Model (GCM), e.g., the Community Earth System Model (CESM) and its predecessors. Because of its reduced size and complexity, the realization of a large number of independent model outputs from a SSM becomes computationally straightforward, so that quantifying the risk associated with low-probability, high-consequence climate events becomes feasible. A Bayesian framework is developed to provide quantitative measures of confidence, via Bayesian credible intervals, in the use of the proposed approach to assess these risks.

The positive bystander effect: passive bystanders increase helping in situations with high expected negative consequences for the helper.

Fischer, Peter; Greitemeyer, Tobias

2013-01-01

The present field study investigated the interplay between the presence of a passive bystander (not present versus present) in a simulated bike theft and expected negative consequences (low versus high) in predicting intervention behavior when no physical victim is present. It was found that an additional bystander increases individual intervention in situations where the expected negative consequences for the helper in case of intervention were high (i.e., when the bike thief looks fierce) compared to situations where the expected negative consequences for the helper were low (i.e., when the bike thief does not look fierce). In contrast, no such effect for high vs. low expected negative consequences was observed when no additional bystander observed the critical situation. The results are discussed in light of previous laboratory findings on expected negative consequences and bystander intervention.

The highs and lows of theoretical interpretation in animal-metacognition research

Smith, J. David; Couchman, Justin J.; Beran, Michael J.

2012-01-01

Humans feel uncertain. They know when they do not know. These feelings and the responses to them ground the research literature on metacognition. It is a natural question whether animals share this cognitive capacity, and thus animal metacognition has become an influential research area within comparative psychology. Researchers have explored this question by testing many species using perception and memory paradigms. There is an emerging consensus that animals share functional parallels with humans’ conscious metacognition. Of course, this research area poses difficult issues of scientific inference. How firmly should we hold the line in insisting that animals’ performances are low-level and associative? How high should we set the bar for concluding that animals share metacognitive capacities with humans? This area offers a constructive case study for considering theoretical problems that often confront comparative psychologists. The authors present this case study and address diverse issues of scientific judgement and interpretation within comparative psychology. PMID:22492748

Long-term biological consequences of nuclear war

Ehrlich, P.R.; Harte, J.; Harwell, M.A.

1983-01-01

Subfreezing temperatures, low light levels, and high doses of ionizing and ultraviolet radiation extending for many months after a large-scale nuclear war could destroy the biological support systems of civilization, at least in the Northern Hemisphere. Productivity in natural and agricultural ecosystems could be severely restricted for a year or more. Postwar survivors would face starvation as well as freezing conditions in the dark and be exposed to near-lethal doses of radiation. If, as now seems possible, the Southern Hemisphere were affected also, global disruption of the biosphere could ensue, In any event, there would be severe consequences, even in the areas not affected directly, because of the interdependence of the world economy. In either case the extinction of a large fraction of the Earth's animals, plants, and microorganisms seems possible. The population size of Homo sapiens conceivably could be reduced to prehistoric levels or below and extinction of the human species itself cannot be excluded. These conclusions are the concensus from the meeting on Long-Term Worldwide Biological Consequences of Nuclear War

Small animal PET: aspects of performance assessment

International Nuclear Information System (INIS)

Weber, Simone; Bauer, Andreas

2004-01-01

Dedicated small animal positron emission tomography (PET) systems are increasingly prevalent in industry (e.g. for preclinical drug development) and biological research. Such systems permit researchers to perform animal studies of a longitudinal design characterised by repeated measurements in single animals. With the advent of commercial systems, scanners have become readily available and increasingly popular. As a consequence, technical specifications are becoming more diverse, making scanner systems less broadly applicable. The investigator has, therefore, to make a decision regarding which type of scanner is most suitable for the intended experiments. This decision should be based on gantry characteristics and the physical performance. The first few steps have been taken towards standardisation of the assessment of performance characteristics of dedicated animal PET systems, though such assessment is not yet routinely implemented. In this review, we describe current methods of evaluation of physical performance parameters of small animal PET scanners. Effects of methodologically different approaches on the results are assessed. It is underscored that particular attention has to be paid to spatial resolution, sensitivity, scatter fraction and count rate performance. Differences in performance measurement methods are described with regard to commercially available systems, namely the Concorde MicroPET systems P4 and R4 and the quad-HIDAC. Lastly, consequences of differences in scanner performance parameters are rated with respect to applications of small animal PET. (orig.)

The nematode Caenorhabditis elegans is a unique whole animal model system for identifying small molecules with in vivo anti-infective properties. C. elegans can be infected with a broad range of human pathogens, including Enterococcus faecalis, an important human nosocomial pathogen with a mortality rate of up to 37% that is increasingly acquiring resistance to antibiotics. Here, we describe an automated, high throughput screen of 37,200 compounds and natural product extracts for those that enhance survival of C. elegans infected with E. faecalis. The screen uses a robot to accurately dispense live, infected animals into 384-well plates, and automated microscopy and image analysis to generate quantitative, high content data. We identified 28 compounds and extracts that were not previously reported to have antimicrobial properties, including 6 structural classes that cure infected C. elegans animals but do not affect the growth of the pathogen in vitro, thus acting by a mechanism of action distinct from antibiotics currently in clinical use. Our versatile and robust screening system can be easily adapted for other whole animal assays to probe a broad range of biological processes. PMID:19572548

Glantz, C.S.; Ballinger, M.Y.; Chapman, E.G.

1986-05-01

This document presents the results of a study commissioned to survey and summarize major environmental monitoring projects in the US-Canadian transboundary region. Projects with field sites located within 400 km (250 mi) of the border and active after 1980 were reviewed. The types of projects included: ambient air-quality monitoring, ambient water-quality monitoring, deposition monitoring, forest/vegetation monitoring and research, soil studies, and ecosystem studies. Ecosystem studies included projects involving the measurement of parameters from more than one monitoring category (e.g., studies that measured both water and soil chemistry). Individual descriptions were formulated for 184 projects meeting the spatial and temporal criteria. Descriptions included the official title for the project, its common abbreviation, program emphasis, monitoring site locations, time period conducted, parameters measured, protocols employed, frequency of sample collection, data storage information, and the principal contact for the project. A summary inventory subdivided according to the six monitoring categories was prepared using a computerized data management system. Information on major centralized data bases in the field of environmental monitoring was also obtained, and summary descriptions were prepared. The inventory and data base descriptions are presented in appendices to this document.

Trade Measures for Regulating Transboundary Movement of Electronic Waste

Directory of Open Access Journals (Sweden)

Gideon Emcee Christian

2017-08-01

Full Text Available International trade in used electrical and electronics equipment (UEEE provides an avenue for socio-economic development in the developing world and also serves as a conduit for transboundary dumping of waste electrical and electronic equipment (WEEE also referred to as electronic waste or e-waste. The latter problem arises from the absence of a regulatory framework for differentiating between functional UEEE and junk e-waste. This has resulted in both functional UEEE and junk e-waste being concurrently shipped to developing countries under the guise of international trade in used electronics. Dealing with these problems will require effective regulation of international trade in UEEE from both exporting and importing countries. Although, the export of e-waste from the European Community to developing countries is currently prohibited, significant amount of e-waste from the region continue to flow into developing countries due to lax regulatory measures in the latter. Hence, there is need for a regulatory regime in developing countries to complement the prohibitory regime in the major e-waste source countries. This paper proposes trade measures modelled in line with WTO rules which could be adopted by developing countries in addressing these problems. The proposed measures include the development of a compulsory certification and labelling system for functional UEEE as well as trade ban on commercial importation of UEEE not complying with the said certification and labelling system. The paper then goes further to examine these proposed measures in the light of WTO rules and jurisprudence.

The parasitic flukes of the genus Fasciola (Platyhelminthes: Trematoda: Digenea) cause fascioliasis or liver-rot disease in ruminant livestock in tropical and sub-tropical regions of the world. Classically, two species of Fasciola- F. hepatica and F. gigantica, are universally recognized as taxonomically valid species. Our survey studies on ovid and bovid animals including yak and mithun from high altitudinal mountainous regions in Northeast India revealed the occurrence of Fasciola gigantica and also Fasciola sp.- an intermediate form, at altitudes between 5000 and 14,085 feet above sea level (asl). Two morphotypes- F. hepatica - like and F. gigantica - like, of Fasciola species were reported from the high altitudinal areas of Northeast India; most of these locales constitute new-locality and first records for the occurrence of these liver flukes.

Pour Biazar, A.; Khan, M. N.; Park, Y. H.; McNider, R. T.; Cameron, B.

2010-12-01

The assessment of potential environmental impact of oil and gas operations in the Gulf of Mexico (GoM) and in particular the onshore air quality impact of such operations is important to State and Federal regulatory agencies. In adapting sound policies for control strategies, it is crucial to assess the impact of local pollution versus transboundary air pollution, and in a region such as GoM with scarce monitoring capability over open waters such distinctions represents a challenge. Furthermore, GoM region can be impacted by the recirculation of pollution in the southeastern United States. The current study examines the efficacy of utilizing the newly available satellite observations of aerosols and trace gases in air quality impacts assessment for addressing these issues. In particular, ozone profiles from the Tropospheric Emission Spectrometer (TES) and Ozone Monitoring Instrument (OMI) onboard Aura and aerosol products from Moderate Resolution Imaging Spectroradiometer (MODIS) onboard Terra and Aqua satellites were utilized in a modeling study during August 2006. The satellite observations were used in the specification of the background and lateral boundary and also once daily for the re-adjustment of the concentration fields. The results were then evaluated against ozonesonde and surface observations. The utilization of OMI ozone profiles significantly improved model performance in the free troposphere and the use of MODIS aerosol products substantially enhanced model prediction of aerosols in the boundary layer. Neither OMI nor TES provide adequate information in the boundary layer with respect to O3 and as a result they can only marginally impact ozone predictions in the boundary layer. The utilization of the satellite data for lateral boundary condition (BC) was helpful in the realization of transboundary transport of pollution. The hypothesis that the recirculation of pollution from Northeast Corridor can play a role over the Gulf of Mexico was tested and

Johnson, Lindsay C; Campbell, Desmond L; Hull, Ethan L; Peterson, Todd E

2011-09-21

We present an initial evaluation of a mechanically cooled, high-purity germanium double-sided strip detector as a potential gamma camera for small-animal SPECT. It is 90 mm in diameter and 10 mm thick with two sets of 16 orthogonal strips that have a 4.5 mm width with a 5 mm pitch. We found an energy resolution of 0.96% at 140 keV, an intrinsic efficiency of 43.3% at 122 keV and a FWHM spatial resolution of approximately 1.5 mm. We demonstrated depth-of-interaction estimation capability through comparison of pinhole acquisitions with a point source on and off axes. Finally, a flood-corrected flood image exhibited a strip-level uniformity of less than 1%. This high-purity germanium offers many desirable properties for small-animal SPECT.

Resurrecting ancient animal genomes: the extinct moa and more.

Science.gov (United States)

Huynen, Leon; Millar, Craig D; Lambert, David M

2012-08-01

Recently two developments have had a major impact on the field of ancient DNA (aDNA). First, new advances in DNA sequencing, in combination with improved capture/enrichment methods, have resulted in the recovery of orders of magnitude more DNA sequence data from ancient animals. Second, there has been an increase in the range of tissue types employed in aDNA. Hair in particular has proven to be very successful as a source of DNA because of its low levels of contamination and high level of ancient endogenous DNA. These developments have resulted in significant advances in our understanding of recently extinct animals: namely their evolutionary relationships, physiology, and even behaviour. Hair has been used to recover the first complete ancient nuclear genome, that of the extinct woolly mammoth, which then facilitated the expression and functional analysis of haemoglobins. Finally, we speculate on the consequences of these developments for the possibility of recreating extinct animals. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Full Text Available The Incomati River Basin is shared by Mozambique, South Africa, and Swaziland. In August 2002, the groundbreaking "Tripartite Interim Agreement on Water Sharing of the Maputo and Incomati Rivers" (the IncoMaputo agreement was signed. Following reports that the use, availability, and adequacy of information posed problems for future decision making on this transboundary river, the Delft University of Technology initiated a 6-month study in 2003 in which 25 southern African researchers and officials were interviewed. The Joint Incomati Basin Study (Phase I from 1992-1995, and Phase II from 2000-2001 formed a central component in the investigation, because it was viewed by the parties involved as a successful experience that paved the way for the IncoMaputo agreement. Knowledge of the role that information played in this process and how decision making occurred was collated and analyzed. Network theory provided the guiding theoretical framework in interpreting the results. A number of problems related to information use in decision making were identified. More importantly, a web of underlying causes was identified, such as cultural and language differences, differences in perception, inadequacy of stakeholder involvement, variability in political commitment, lack of capacity, absence of operational experience, the weak mandate of the international decision-making body, and the paradoxical South African-Mozambican relationship. Two groups of factors in this web were identified as needing to change if the management of this transboundary river is to comply with the IncoMaputo agreement, namely the situational or institutional factors and the cognitive factors (particularly the perceptions each country holds of the other and the way they treat one another. Our analysis shows that, contrary to current international practice, when designing international institutional arrangements for water management, the sociopolitical interface should be considered

Drivers of illegal livelihoods in remote transboundary regions: the case of the Trans-Fly region of Papua New Guinea

Full Text Available Remote transboundary regions in developing countries often contain abundant natural resources. Many of these resources are being overexploited to supply an ever-increasing demand from Asia, often via illegal cross-border trade. Understanding the systemic issues that drive households to engage in illegal activities in transboundary regions is a prerequisite for designing effective interventions and diverting livelihoods toward sustainable trajectories, but is rarely applied. This study analyzed the drivers of illegal trade in marine products, e.g. sea cucumber, shark fin, and fish bladders, among coastal villages in Papua New Guinea that border Indonesia and Australia in the Trans-Fly region. Mixed-methods (household questionnaire surveys, focus group discussions, and key informant interviews were applied to triangulate results and minimize denial bias, which is a challenge when studying illegality. Results indicated that distance from markets and economic centers was the main driver for engagement in illegal activity, and distance from a center was also the main driver of poverty. Contrary to studies elsewhere, we found that poverty did not generally drive households' engagement in illegal trade. Only in Daru, the primary economic hub, where immigrants from the areas impacted by the Ok Tedi mine operations have resettled, were the poorest households likely to be involved in illegal trade, because they had no alternative sources of livelihood. Weak governance exacerbates the situation, which includes corruption, a lack of enforcement, and poor coordination among government levels, and a breakdown of traditional resource management systems. Respondents highlighted that current bilateral border agreements are outdated and cannot account for modernization, a globalizing economy, and communities' rapid transition to a cash economy. Our findings emphasize the need to find innovative governance solutions to manage this stressed social

Over the last decade, small-animal PET imaging has become a vital platform technology in cancer research. With the development of molecularly targeted therapies and drug combinations requiring evaluation of different schedules, the number of animals to be imaged within a PET experiment has increased. This paper describes experimental design requirements to reach statistical significance, based on the expected change in tracer uptake in treated animals as compared to the control group, the number of groups that will be imaged, and the expected intra-animal variability for a given tracer. We also review how high-throughput studies can be performed in dedicated small-animal PET, high-resolution clinical PET systems and planar positron imaging systems by imaging more than one animal simultaneously. Customized beds designed to image more than one animal in large-bore small-animal PET scanners are described. Physics issues related to the presence of several rodents within the field of view (i.e. deterioration of spatial resolution and sensitivity as the radial and the axial offsets increase, respectively, as well as a larger effect of attenuation and the number of scatter events), which can be assessed by using the NEMA NU 4 image quality phantom, are detailed.

Lost or discarded fishing nets are a significant component of marine debris which has trans-boundary impacts in large marine ecosystems. Such 'ghost nets' cause the by-catch of marine fauna and require retrieval from coastlines where they wash up. Identifying the causes of discarded nets and feasible intervention points requires analysis of a complex value chain and the stakeholders within it, yet no studies have attempted this. In this paper we combine Value Chain Analysis, commonly applied to understand value-adding for a commodity, with elements of Life Cycle Assessment and social network analysis to examine the drivers, stakeholders, economic, environmental and social costs and benefits in the life of a trawl net. We use the Arafura Sea as a case study, which is shared by Indonesia, Papua New Guinea and Australia, and is the focus of a Trans-boundary Diagnostic Assessment (TDA) within the Arafura-Timor Seas Ecosystem Action program (ATSEA). We follow a trawl net through four sub-systems: manufacture of webbing in South Korea, fishing and loss by an Indonesian vessel, retrieval as ghost net on the northern Australian coastline by Indigenous rangers, and disposal or re-cycling as 'GhostNet Art' by Indigenous artists. Primary stakeholders along the value chain incur economic and social benefits, and economic and environmental costs. There is an anomaly in the chain between Indonesian fishermen and Indigenous rangers, artists and communities due to the lack of market linkages between these primary stakeholders. The first 'nexus of influence' where reductions in net losses and environmental costs can be achieved is through interactions between GhostNets Australia, the World Wide Fund for Nature and the Australian Government, which can influence Indonesian fishery management institutions and fishing crews. The second nexus is via the international art market which by publicising GhostNet Art can raise awareness amongst fish consumers about the impacts of ghost nets

Rabies in Iraq: trends in human cases 2001-2010 and characterisation of animal rabies strains from Baghdad.

Directory of Open Access Journals (Sweden)

Daniel L Horton

Full Text Available Control of rabies requires a consistent supply of dependable resources, constructive cooperation between veterinary and public health authorities, and systematic surveillance. These are challenging in any circumstances, but particularly during conflict. Here we describe available human rabies surveillance data from Iraq, results of renewed sampling for rabies in animals, and the first genetic characterisation of circulating rabies strains from Iraq. Human rabies is notifiable, with reported cases increasing since 2003, and a marked increase in Baghdad between 2009 and 2010. These changes coincide with increasing numbers of reported dog bites. There is no laboratory confirmation of disease or virus characterisation and no systematic surveillance for rabies in animals. To address these issues, brain samples were collected from domestic animals in the greater Baghdad region and tested for rabies. Three of 40 brain samples were positive using the fluorescent antibody test and hemi-nested RT-PCR for rabies virus (RABV. Bayesian phylogenetic analysis using partial nucleoprotein gene sequences derived from the samples demonstrated the viruses belong to a single virus variant and share a common ancestor with viruses from neighbouring countries, 22 (95% HPD 14-32 years ago. These include countries lying to the west, north and east of Iraq, some of which also have other virus variants circulating concurrently. These results suggest possible multiple introductions of rabies into the Middle East, and regular trans-boundary movement of disease. Although 4000 years have passed since the original description of disease consistent with rabies, animals and humans are still dying of this preventable and neglected zoonosis.

The state of transboundary air pollution 1992 update. Report prepared within the framework of the Convention on Long-range Transboundary Air Pollution

International Nuclear Information System (INIS)

1993-01-01

This ninth volume of the series of Air Pollution Studies, published under the auspices of the Executive Body for the Convention on Long-range Transboundary Air Pollution, contains documents reviewed and approved for publication at the tenth session of the Executive Body held at Geneva from 17 to 19 November 1992. Part One is the Annual Review of Strategies and Policies for Air Pollution Abatement. It is compiled on the basis of national data and reports received up to 31 December 1992. National emission data and forecasts for sulphur dioxide (SO 2 ), nitrogen oxides (NO x ), volatile organic compounds (VOCs), ammonia (NH 3 ), and carbon dioxide (CO 2 ) from 1980 to the year 2005 is presented. Part Two contains results of scenario analysis for sulphur abatement strategies. It is concluded, inter alia, that strategies can be found which, by differentiating emission reductions, provide greater environmental benefit than a uniform reduction at the same cost. It is also shown that a small number of high-emitting countries in Central Europe have significant impact on deposition of sulphur throughout Europe, and that emission reduction in these countries proves to be a cost-effective way of moving towards critical loads in Europe as a whole. Most of the scenarios analysed are based on reductions of current deposition in relation to critical loads, i.e., a decrease in the exceedances of critical loads. Part Three is an executive summary of the 1992 Report on Forest Condition in Europe, carried out under the International Cooperative Programme for Assessment and Monitoring of Air Pollution Effects on Forests. The full report has been jointly published by ECE and the Commission of the European Communities. It summarizes the results of surveys carried out in 1991 in 28 European countries and in several additional regions, conducted in accordance with common guidelines. Of 214 million hectares of forest in Europe (including major parts of the forests in the western part of the

Motivation for Palatable Food Despite Consequences in an Animal Model of Binge-Eating

2010-01-01

Objective Binge-eating involves an abnormal motivation for highly palatable food in that these foods are repeatedly consumed despite their binge-triggering effects and life-affecting consequences associated with binge-eating. We determined if rats identified as binge-eating prone (BEP) similarly display abnormal motivation for palatable food. Method Food-sated BEP and binge-eating resistant (BER) rats were given voluntary access to palatable food paired with increasing intensity of footshock. Later, they were exposed to a period of cyclic caloric restriction-refeeding. Results BEPs consumed significantly more and tolerated higher levels of footshock for palatable food than BERs. Cyclic restriction-refeeding increased BERs' tolerance of shock for palatable food. Discussion Previously observed parallels of the rat BEP model to human binge-eating can now be extended to include an abnormal motivation for palatable food. This model should prove useful in identifying specific genes that interact with the nutritional environment to mediate binge-eating and may point to novel physiological targets to treat compulsive overeating.

Risk-averse decision-making for civil infrastructure exposed to low-probability, high-consequence events

International Nuclear Information System (INIS)

Cha, Eun Jeong; Ellingwood, Bruce R.

2012-01-01

Quantitative analysis and assessment of risk to civil infrastructure has two components: probability of a potentially damaging event and consequence of damage, measured in terms of financial or human losses. Decision models that have been utilized during the past three decades take into account the probabilistic component rationally, but address decision-maker attitudes toward consequences and risk only to a limited degree. The application of models reflecting these attitudes to decisions involving low-probability, high-consequence events that may impact civil infrastructure requires a fundamental understanding of risk acceptance attitudes and how they affect individual and group choices. In particular, the phenomenon of risk aversion may be a significant factor in decisions for civil infrastructure exposed to low-probability events with severe consequences, such as earthquakes, hurricanes or floods. This paper utilizes cumulative prospect theory to investigate the role and characteristics of risk-aversion in assurance of structural safety.

An API task group has developed a process for the assessment of existing platforms to determine their fitness for purpose. This has been released as a draft supplement to API RP 2A-WSD, 20th edition. Details and the background of this work are described in a companion paper. The assessment of a platform's fitness for purpose involves firstly a definition of the platform's exposure; and secondly, an evaluation of the platform's predicted performance relative to the assessment criteria associated with that exposure. This paper deals with platforms in the high exposure category. That is, platforms whose potential failure consequences, in terms of potential life loss and environmental damage, are significant. The criteria for placement of a platform in a high exposure category are explained, as are the performance criteria demanded of these high exposure platforms. In the companion paper, the metocean assessment process and associated API-developed acceptance criteria are highlighted. This paper addresses primarily ice and seismic loading assessments and associated API-developed criteria, which are based on over thirty years of successful offshore operation and field experience, as well as extrapolation of land-based performance criteria. Three West Coast, USA production platforms are used for illustration

This fifth volume of the series of Air Pollution Studies, published under the auspices of the Executive Body for the Convention of Long-range Transboundary Air Pollution, contains the documents reviewed and approved for publication at the sixth session of the Executive Body held at Sofia (Bulgaria) from 31 October to 4 November 1988. Part one is the annual review of strategies and policies for air pollution abatement. Country-by-country, recent legislative and regulatory developments are summarized, including ambient-air quality standards, fuel-quality standards, emission standards, as well as economic instruments for air pollution abatement. Part two summarizes the results of the third phase (1984-1986) of the Co-operative Programme for Monitoring and Evaluation of the Long-range Transmission of Air Pollutants in Europe (EMEP). Part three is an executive summary of the 1987 forest damage survey in Europe, carried out under the International Co-operative Programme for Assessment and Monitoring of Air Pollution Effects on Forests. This survey covered more than 50 per cent of all coniferous forests and about 40 per cent of the broadleaved forests in Europe. Part four describes the current geographical extent of acidification in rivers, lakes and reservoirs in the ECE region. Part five contains guidelines for determining the cost of emission control activities. The guidelines aim at harmonizing cost estimates and cost accounts for anti-pollution measures at the level of individual plants or companies. The proposed calculation scheme includes cost items related to investment, material and energy consumption, manpower and other costs, taking into account depreciation and revenues from by-product utilization.

Antibiotics in Animal Products

Falcão, Amílcar C.

The administration of antibiotics to animals to prevent or treat diseases led us to be concerned about the impact of these antibiotics on human health. In fact, animal products could be a potential vehicle to transfer drugs to humans. Using appropri ated mathematical and statistical models, one can predict the kinetic profile of drugs and their metabolites and, consequently, develop preventive procedures regarding drug transmission (i.e., determination of appropriate withdrawal periods). Nevertheless, in the present chapter the mathematical and statistical concepts for data interpretation are strictly given to allow understanding of some basic pharma-cokinetic principles and to illustrate the determination of withdrawal periods

Autin, Ludovic; Tufféry, Pierre

2007-01-01

The Protein Movie Generator (PMG) is an online service able to generate high-quality pictures and animations for which one can then define simple storyboards. The PMG can therefore efficiently illustrate concepts such as molecular motion or formation/dissociation of complexes. Emphasis is put on the simplicity of animation generation. Rendering is achieved using Dino coupled to POV-Ray. In order to produce highly informative images, the PMG includes capabilities of using different molecular representations at the same time to highlight particular molecular features. Moreover, sophisticated rendering concepts including scene definition, as well as modeling light and materials are available. The PMG accepts Protein Data Bank (PDB) files as input, which may include series of models or molecular dynamics trajectories and produces images or movies under various formats. PMG can be accessed at http://bioserv.rpbs.jussieu.fr/PMG.html. PMID:17478496

Expected consequences of convenience euthanasia perceived by veterinarians in Quebec

2017-01-01

In companion animal practice, convenience euthanasia (euthanasia of a physically and psychologically healthy animal) is recognized as one of the most difficult situations. There is little published on veterinary perceptions of the consequences of convenience euthanasia. A qualitative study on the subject based on interviews with 14 veterinarians was undertaken. The animal’s interests in the dilemma of convenience euthanasia was taken into consideration, strictly from the point of view of the physical suffering and stress related to the procedure. The veterinarian’s goal was to respect the animal’s interests by controlling physical pain. Most often, veterinarians made their own interests and those of the owners a priority when considering the consequences of their decision to perform or refuse convenience euthanasia. PMID:28698691

Reversing course: Germany`s response to the challenge of transboundary air pollution

Energy Technology Data Exchange (ETDEWEB)

Sprinz, D.F.; Wahl, A.

1998-03-01

Perhaps like no other country, Germany has radically changed its policies towards regulating air pollution in the European context. Acting originally as a dragger in the 1970s to regulate transboundary air pollutants due to pessimism about the relationship between causes and effects, Germany responded very decisively to its own damage assessment in the early 1980s. In particular the adverse effects to forests (`Waldsterben` or forest decline) led to the formulation of strict air pollution regulations in the domestic context, efforts to spread the regulatory system within the European Union, and activities within the United Nations Economic Commission for Europe to foster stronger, continent-wide emission reductions. Using three conceptual models (rational actor, domestic politics, and social learning), we show that Germany deviated strongly from the ideal policy cycle consisting of (i) domestic policy formulation, (ii) international negotiations, as well as (iii) implementation and compliance with the provisions of international environmental agreements. Both national policy-making as well as partial implementation have been well on the way towards compliance even before Germany entered international negotiations on substantive protocols. Therefore, one may conclude from this country study that push countries may use the results of their national policy processes to influence the policy of other countries. (orig.)

State of the Crown of the continent ecosystem : Flathead/Castle Transboundary Bioregion (draft)

Energy Technology Data Exchange (ETDEWEB)

Konrad, E.; Peck, B.; Stewart, A.; Stewart, C.

1999-01-01

This state of the ecosystem report describes the ecological composition of the Flathead/Castle Transboundary bioregion, including human activity. The ecosystem (which does not follow political boundaries) extends from western Alberta, eastern British Columbia and Montana. The region encompasses 5088 square km. and occupies two watersheds of the greater Crown of the Continent Ecosystem. Ecological components of the North Fork of the Flathead and of the Castle Drainage including such ecological processes as fire and disease, vegetation, species, wildlife, the aquatic environment, and a century of human activity in the two regions are described. Forestry practices, petroleum extraction, mining, recreational activities, land development, ranching practices, and road development in the two regions are reviewed, along with ecosystem-wide trends. The advantages of ecosystem based management integrated with human based management practices was demonstrated by describing the Rocky Mountain Grizzly Bear Planning Committee`s work . The Committee consists of representatives of wildlife agencies of Montana, BC, Alberta and Canadian and US federal government agencies who share responsibility for jointly mapping grizzly habitat, grizzly mortality sinks, pooling data on mortalities to ensure that the regional grizzly bear population is managed as one population regardless of political boundaries. 221 refs., tabs., figs.

[Mycoses in domestic animals].

Science.gov (United States)

García, M E; Blanco, J L

2000-03-01

In the present paper we will present a general view of the main mycoses affecting domestic animals. In the dog, we show the importance of the dermatophytoses, increased by its zoonosic character and the problem of the false negatives in the traditional microbiological culture. Under the general term of systemic mycoses we include a series of conditions considered usually as aspergillosis, bat with more and more fungal species implicated as possible etiological agents. In addition, fungi, especially yeasts, are being implicated in canine otitis; in our laboratory 86 % of canine chronic otitis involve a yeast etiology, alone or in collaboration with bacteria. In the cat, dermatophytes are more common than in the dog, and are the main source of infection in man, with the description of a high percentage of healthy carrier animals. Cryptococcosis is a severe disease, usually secondary to other process, especially feline immunodeficiency. In cows we refer to fungal abortion, with three main fungi implicated: Aspergillus, Candida and Zygomycetes. In some areas of our country the percentage of fungal abortion is around 10 %. A consequence of the multiple use of antibiotics in mastitis is selection of yeasts, especially those included in the genera Candida and Cryptococcus. Bovine dermatophytoses is an extensively disseminated disease in our country, with a commercial specific vaccine available. In small ruminants, Cryptococcus causes severe pneumonic processes that could be confused clinically with other conditions. An additional important question is the description of isolation of this fungus from tree leaves. In poultry, aspergillosis is a known and controlled disease, but with more importance in captive wild birds with an ecological value. In horses, we emphasize the lung infections by different fungi, specially Pneumocystis carinii, and arthritis by yeasts as consequence of wound contamination or surgery.

2012-11-01

Dermatomycoses due to contact with pets and livestock frequently affect children and young adults. Zoophilic dermatophytes are the main important causative agents. It has long been known that the often high inflammatory dermatophytoses of the skin and the scalp are caused mostly by Microsporum canis. Due to an absence of an obligation for reporting fungal infections of the skin to the Public Health Office in Germany, an unnoticed but significant change in responsible pathogens has occurred. Today an increasing number of infections due to zoophilic strains of Trichophyton interdigitale (formerly Trichophyton mentagrophytes) and Trichophyton species of Arthroderma benhamiae are found. The latter mentioned dermatophyte is the anamorph species of the teleomorph Arthroderma benhamiae, which originally was isolated in the Far East (Japan). Source of infection of these dermatophytes are small rodents, in particular guinea pigs. These animals are bought in pet shops by the parents of those children who later are affected by the fungal infection. The coincidental purchase of the relevant fungal pathogen is not obvious to the parents. As a consequence, highly contagious dermatophytoses occur, often tinea capitis sometimes with kerion formation. Further dermatophytes should be considered as cause of a zoophilic dermatomycosis. Both Trichophyton verrucosum, the cause of the ringworm in cattle, and Trichophyton erinacei following contact to hedgehogs are worthy of note. Yeasts cannot be ignored as cause of dermatomycosis, especially Malassezia pachydermatis, the only non-lipophilic species within the genus Malassezia, which can be transferred from dog to men. Cryptococcus neoformans also comes from animal sources. The mucous yeast occurs in bird's dropping, and it causes both pulmonary and central nervous system infections, but also primary and secondary cutaneous cryptococcosis in immunocompromised patients (HIV/AIDS) as possible consequence after contact to these animals.

Renal Aging: Causes and Consequences.

O'Sullivan, Eoin D; Hughes, Jeremy; Ferenbach, David A

2017-02-01

Individuals age >65 years old are the fastest expanding population demographic throughout the developed world. Consequently, more aged patients than before are receiving diagnoses of impaired renal function and nephrosclerosis-age-associated histologic changes in the kidneys. Recent studies have shown that the aged kidney undergoes a range of structural changes and has altered transcriptomic, hemodynamic, and physiologic behavior at rest and in response to renal insults. These changes impair the ability of the kidney to withstand and recover from injury, contributing to the high susceptibility of the aged population to AKI and their increased propensity to develop subsequent progressive CKD. In this review, we examine these features of the aged kidney and explore the various validated and putative pathways contributing to the changes observed with aging in both experimental animal models and humans. We also discuss the potential for additional study to increase understanding of the aged kidney and lead to novel therapeutic strategies. Copyright © 2017 by the American Society of Nephrology.

Antibiotics in animal feed and their role in resistance development

DEFF Research Database (Denmark)

Wegener, Henrik Caspar

2003-01-01

Animals and humans constitute overlapping reservoirs of resistance, and consequently use of antimicrobials in animals can impact on public health. For example, the occurrence of vancomycin-resistant enterococci in food-animals is associated with the use of avoparcin, a glycopeptide antibiotic used...... as a feed additive for the growth promotion of animals. Vancomycin-resistant enterococci and vancomycin resistance determinants can therefore spread from animals to humans. The bans on avoparcin and other antibiotics as growth promoters in the EU have provided scientists with a unique opportunity......, the effects on animal health and productivity have been very minor....

Animal coloration research: why it matters.

Caro, Tim; Stoddard, Mary Caswell; Stuart-Fox, Devi

2017-07-05

While basic research on animal coloration is the theme of this special edition, here we highlight its applied significance for industry, innovation and society. Both the nanophotonic structures producing stunning optical effects and the colour perception mechanisms in animals are extremely diverse, having been honed over millions of years of evolution for many different purposes. Consequently, there is a wealth of opportunity for biomimetic and bioinspired applications of animal coloration research, spanning colour production, perception and function. Fundamental research on the production and perception of animal coloration is contributing to breakthroughs in the design of new materials (cosmetics, textiles, paints, optical coatings, security labels) and new technologies (cameras, sensors, optical devices, robots, biomedical implants). In addition, discoveries about the function of animal colour are influencing sport, fashion, the military and conservation. Understanding and applying knowledge of animal coloration is now a multidisciplinary exercise. Our goal here is to provide a catalyst for new ideas and collaborations between biologists studying animal coloration and researchers in other disciplines.This article is part of the themed issue 'Animal coloration: production, perception, function and application'. © 2017 The Author(s).

Ethical dilemmas encountered by small animal veterinarians: characterisation, responses, consequences and beliefs regarding euthanasia.

Science.gov (United States)

Kipperman, Barry; Morris, Patricia; Rollin, Bernard

2018-05-12

Small animal veterinarians' opinions were investigated regarding the frequency and nature of ethical dilemmas encountered, beliefs regarding euthanasia and balancing client and animal interests, prevalence and value of ethics training and proposals to mitigate the stressful effects of ethical dilemmas. The majority (52 per cent) of 484 respondents in the USA indicated via an online survey experiencing an ethical dilemma regarding the interests of clients and those of their patients at least weekly. Scenarios involving client financial concerns were commonly reported causes of ethical conflicts. While only 20 per cent of respondents indicated that other practitioners prioritise patient interests, 50 per cent of respondents characterised their own behaviour as prioritising patients. Most respondents (52 per cent) reported that ethical dilemmas are the leading cause, or are one of many equal causes, of work-related stress. Less experienced practitioners, general practitioners and associate veterinarians were more likely to encounter situations they defined as ethical dilemmas, and female respondents were more likely to find ethical dilemmas stressful. Most small animal veterinarians experience ethical dilemmas regularly, which contribute to moral stress. Results suggested that most small animal practitioners believe that greater awareness of moral stress and providing training in ethical theories and tools for coping with ethical dilemmas can ameliorate moral stress. © British Veterinary Association (unless otherwise stated in the text of the article) 2018.

The absence or loss of rewards or reinforcers holds a major role in the development of depression in humans. In spite of the prevalence of extinction-induced depression (EID) in humans, few attempts have been made to establish animal models thereof. Here we present the concept of extinction-related depression and summarize the results of two sets of studies in our attempt to create animal models of EID, one set based on extinction after positive reinforcement in the Skinner-box, the other on extinction after negative reinforcement - escape from water. We found various behaviors emitted during the extinction trials that responded to treatment with antidepressant drugs: Accordingly, the important behavioral marker for EID during extinction of escape from the water was immobility. During extinction after positive reinforcement the important indices for extinction-induced depression are the withdrawal from the former site of reward, biting behavior and rearing up on the hind legs. Avoidance behavior and biting may model aspects of human depressive behavior, which may include withdrawal or avoidance as well as aggressive-like behaviors. Copyright © 2013 Elsevier Ltd.

The nematode Caenorhabditis elegans is a unique whole animal model system for identifying small molecules with in vivo anti-infective properties. C. elegans can be infected with a broad range of human pathogens, including Enterococcus faecalis, an important human nosocomial pathogen. Here, we describe an automated, high-throughput screen of 37,200 compounds and natural product extracts for those that enhance survival of C. elegans infected with E. faecalis. Using a robot to dispense live, infected animals into 384-well plates and automated microscopy and image analysis, we identified 28 compounds and extracts not previously reported to have antimicrobial properties, including six structural classes that cure infected C. elegans animals but do not affect the growth of the pathogen in vitro, thus acting by a mechanism of action distinct from antibiotics currently in clinical use.

Potential of plant polyphenols to combat oxidative stress and inflammatory processes in farm animals.

Gessner, D K; Ringseis, R; Eder, K

2017-08-01

Polyphenols are secondary plant metabolites which have been shown to exert antioxidative and antiinflamma tory effects in cell culture, rodent and human studies. Based on the fact that conditions of oxidative stress and inflammation are highly relevant in farm animals, polyphenols are considered as promising feed additives in the nutrition of farm animals. However, in contrast to many studies existing with model animals and humans, potential antioxidative and antiinflammatory effects of polyphenols have been less investigated in farm animals so far. This review aims to give an overview about potential antioxidative and antiinflammatory effects in farm animals. The first part of the review highlights the occurrence and the consequences of oxidative stress and inflammation on animal health and performance. The second part of the review deals with bioavailability and metabolism of polyphenols in farm animals. The third and main part of the review presents an overview of the findings from studies which investigated the effects of polyphenols of various plant sources in pigs, poultry and cattle, with particular consideration of effects on the antioxidant system and inflammation.

Animal science: Isotopes and nuclear techniques

Vercoe, J.E.

In many regions of the world, animal production is limited by poor growth, reproductive performance and milk output of livestock, thus limiting the availability of animal products such as meat, milk, leather, etc., for use by man. Reduced animal production results from inadequate or unbalanced nutrition, lack of adaptation to climatic conditions, and parasitic and other diseases The production from animals can be improved on the one hand by improving genotypes (the breeds and strains within a given species) to make them better suited to the environment to which they are exposed, and on the other hand by modifying the components of the environment which are limiting the production. In practice, a combination of these two strategies is usually desirable but the relative importance of each is determined by short- and long-term economic considerations and the likely environmental consequences. Isotopes and radiation play an important part in identifying and alleviating the genetic and environmental limitations to animal production

X-ray computed tomography of small animals and their organs is an essential tool in basic and preclinical biomedical research. In both phase-contrast and absorption tomography high spatial resolution and short exposure times are of key importance. However, the observable spatial resolutions and achievable exposure times are presently limited by system parameters rather than more fundamental constraints like, e.g., dose. Here we demonstrate laboratory tomography with few-ten μm spatial resolution and few-minute exposure time at an acceptable dose for small-animal imaging, both with absorption contrast and phase contrast. The method relies on a magnifying imaging scheme in combination with a high-power small-spot liquid-metal-jet electron-impact source. The tomographic imaging is demonstrated on intact mouse, phantoms and excised lungs, both healthy and with pulmonary emphysema.

Social and ecological aspects of the water resources management of the transboundary rivers of Central Asia

Full Text Available The Zeravshan River is a transboundary river whose water is mainly used for irrigation of agricultural lands of the Republic of Uzbekistan. Sufficiently rich hydropower resources in upstream of the Zeravshan River characterize the Republic of Tajikistan. Continuous monitoring of water resources condition is necessary for planning the development of this area taking into account hydropower production and irrigation needs. Water quality of Zeravshan River is currently one of the main problems in the relationship between the Republics of Uzbekistan and Tajikistan, and it frequently triggers conflict situations between the two countries. In most cases, the problem of water quality of the Zeravshan River is related to river pollution by wastewater of the Anzob Mountain-concentrating Industrial Complex (AMCC in Tajikistan. In this paper results of research of chemical and bacteriological composition of the Zeravshan River waters are presented. The minimum impact of AMCC on quality of water of the river was experimentally established.

Spatial-Temporal Dynamics of High-Resolution Animal Networks: What Can We Learn from Domestic Animals?

Full Text Available Animal social network is the key to understand many ecological and epidemiological processes. We used real-time location system (RTLS to accurately track cattle position, analyze their proximity networks, and tested the hypothesis of temporal stationarity and spatial homogeneity in these networks during different daily time periods and in different areas of the pen. The network structure was analyzed using global network characteristics (network density, subgroup clustering (modularity, triadic property (transitivity, and dyadic interactions (correlation coefficient from a quadratic assignment procedure at hourly level. We demonstrated substantial spatial-temporal heterogeneity in these networks and potential link between indirect animal-environment contact and direct animal-animal contact. But such heterogeneity diminished if data were collected at lower spatial (aggregated at entire pen level or temporal (aggregated at daily level resolution. The network structure (described by the characteristics such as density, modularity, transitivity, etc. also changed substantially at different time and locations. There were certain time (feeding and location (hay that the proximity network structures were more consistent based on the dyadic interaction analysis. These results reveal new insights for animal network structure and spatial-temporal dynamics, provide more accurate descriptions of animal social networks, and allow more accurate modeling of multiple (both direct and indirect disease transmission pathways.

Assessing basin heterogeneities for rainfall–runoff modelling of the Okavango River and its transboundary management

Directory of Open Access Journals (Sweden)

V. Baumberg

2014-09-01

Full Text Available The neighbouring river systems Cubango and Cuito drain the southeastern part of the Angolan Highlands and form the Okavango River after their confluence, thus providing 95% of the Okavango River discharge. Although they are characterised by similar environmental conditions, runoff records indicate remarkable differences regarding the hydrological dynamics. The Cubango River is known for rapid discharges with high peaks and low baseflow whereas the Cuito runoff appears more balanced. These differences are mainly caused by heterogeneous geological conditions or terrain features. The Cubango headwaters are dominated by crystalline bedrock and steeper, v-shaped valleys while the Cuito system is characterised by wide, swampy valleys and thick sand layers, thus attenuating runoff. This study presents model exercises which have been performed to assess and quantify these effects by applying the distributive model J2000g for each sub-basin. The models provide reasonable results representing the spatio-temporal runoff pattern, although some peaks are over- or underestimated, particularly in the Cuito catchment. This is explained by the scarce information on extent and structure of storages, such as aquifers or swamps, in the Cuito system. However, the model results aid understanding of the differences of both tributaries in runoff generation and underpin the importance of floodplains regarding the control of runoff peaks and low flows in the Cuito system. Model exercises reveal that basin heterogeneity needs to be taken into account and must be parameterised appropriately for reliable modelling and assessment of the entire Okavango River basin for managing the water resources of the transboundary Okavango River in a harmonious way.

Effects and control of long-range transboundary air pollution. Report prepared within the framework of the Convention on Long-range Transboundary Air Pollution

International Nuclear Information System (INIS)

1995-01-01

This eleventh volume of the series of Air Pollution Studies, published under the auspices of the Executive Body for the Convention on Long-range Transboundary Air Pollution, contains the documents reviewed and approved for publication at the twelfth session of the Executive Body held at Geneva from 28 November to 1 December 1994. Part one focuses on the possible impact of acid deposition on the quality of groundwater in the ECE region. The objective of this report is to present an updated review of available knowledge on the possible impact of deposition of sulphur and nitrogen compounds on the status of groundwater, including a brief survey of recent research results in this field. It updates an earlier report on the effects of air pollutants on groundwater, prepared within the Convention (EB.AIR/WG.1/R.9). Part two is an executive summary of the 1993 Report on the Forest Condition in Europe (Forest Condition in Europe. Results of the 1993 Survey. 1994 Report, EC-UN/ECE, Brussels, Geneva, 1994). The report describes the results of both the national and the transnational surveys which are conducted annually within the International Cooperative Programme on the Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests) of the United Nations Economic Commission for Europe (ECE) and under European Community Council Regulation (EEC) 3528/86 on the protection of the Community's Forests against Atmospheric Pollution. Part three is a summary report on the options for further reduction of nitrogen oxide emissions from road heavy-duty vehicles (HDVs). This report is primarily focused on reduction options for road HDVs, but some of the technical measures reviewed can, however, also be applied to some non-road diesel engines, such as machinery in construction, agriculture or forestry

Mainstreaming animal-assisted therapy.

2010-01-01

The term animal-assisted therapy (AAT) commonly refers to the presentation of an animal to one or more persons for the purpose of providing a beneficial impact on human health or well-being. AAT is an ideal example of "One Health" because of numerous studies and widespread testimonials indicating that many humans feel better in the presence of pets and other domesticated animals, and, conversely, that some of those creatures appear to respond positively to human company for their emotional and perhaps physical betterment. Many AAT studies have claimed a wide range of human health benefits, but much of the research is characterized by small-scale interventions among disparate fields, resulting in criticisms about weak study design or inconsistent methodology. Such criticisms contrast with the strongly held belief among many that interaction with friendly animals has a strong and innate value for the persons involved. Consequently the appeal of AAT in human medicine today may be generally characterized as a "push" by enthusiastic advocates rather than a "pull" by prescribing physicians. To fully integrate AAT into conventional medical practice as an accepted therapeutic modality, more convincing intervention studies are necessary to confirm its clinical merits, along with an understanding of the underlying mechanism of the human response to the company of friendly animals.

Impact of the economic recession on companion animal relinquishment, adoption, and euthanasia: a Chicago animal shelter's experience.

Weng, Hsin-Yi; Hart, Lynette A

2012-01-01

This study investigated how the current economic recession (since December 2007) has affected dog and cat relinquishment, adoption, and euthanasia at the Anti-Cruelty Society animal shelter in Chicago, Illinois. The study compared temporal patterns of the investigated statistics before (2000-2007) the start of the current recession with the patterns after the start of the recession (2008-2010). The results showed that once the guardianship (ownership) of a nonhuman animal had been established, the recession did not greatly affect the owner's decision on relinquishment-except for the relinquishment of senior dogs, which may be associated with increased costs of care. However, an unfavorable economic environment may have reduced adoption of animals. The consequences of a decline in adoptions might be reflected in an increase in the proportion or number of sheltered animals euthanized. This study demonstrated how monitoring changes in temporal patterns in these shelter statistics can help guide animal shelters to better prepare for the current recession.

Low-Probability High-Consequence (LPHC) Failure Events in Geologic Carbon Sequestration Pipelines and Wells: Framework for LPHC Risk Assessment Incorporating Spatial Variability of Risk

If Carbon dioxide Capture and Storage (CCS) is to be effective in mitigating climate change, it will need to be carried out on a very large scale. This will involve many thousands of miles of dedicated high-pressure pipelines in order to transport many millions of tonnes of CO₂ annually, with the CO₂ delivered to many thousands of wells that will inject the CO₂ underground. The new CCS infrastructure could rival in size the current U.S. upstream natural gas pipeline and well infrastructure. This new infrastructure entails hazards for life, health, animals, the environment, and natural resources. Pipelines are known to rupture due to corrosion, from external forces such as impacts by vehicles or digging equipment, by defects in construction, or from the failure of valves and seals. Similarly, wells are vulnerable to catastrophic failure due to corrosion, cement degradation, or operational mistakes. While most accidents involving pipelines and wells will be minor, there is the inevitable possibility of accidents with very high consequences, especially to public health. The most important consequence of concern is CO₂ release to the environment in concentrations sufficient to cause death by asphyxiation to nearby populations. Such accidents are thought to be very unlikely, but of course they cannot be excluded, even if major engineering effort is devoted (as it will be) to keeping their probability low and their consequences minimized. This project has developed a methodology for analyzing the risks of these rare but high-consequence accidents, using a step-by-step probabilistic methodology. A key difference between risks for pipelines and wells is that the former are spatially distributed along the pipe whereas the latter are confined to the vicinity of the well. Otherwise, the methodology we develop for risk assessment of pipeline and well failures is similar and provides an analysis both of the annual probabilities of

Animal Poetry and Empathy

Directory of Open Access Journals (Sweden)

Tirza Brüggemann

2017-04-01

Full Text Available This article discusses how our ideas of empathy are influenced by the dichotomy of mind versus body, also known as Cartesian dualism. Within the aesthetic field, this dichotomy is seen when researchers define narrative empathy as imaginatively reconstructing the fictional character’s thoughts and feelings. Conversely, the empathy aroused by a non-narrative work of art is seen as an unconscious bodily mirroring of movements, postures or moods. Thinking dualistically does not only have consequences for what we consider human nature; it also affects our view on animals. To show the untenability of dualistic thinking, this article focuses on the animal poetry genre. Using the ideas of the French phenomenologist Maurice Merleau-Ponty, I analyze two animal poems: “Inventing a Horse” by Meghan O’Rourke and “Spermaceti” by Les Murray. The analysis of these two poems suggests that the presiding ideas about aesthetic empathy and empathy in general need re-evaluation.

The flaws and human harms of animal experimentation.

Science.gov (United States)

Akhtar, Aysha

2015-10-01

Nonhuman animal ("animal") experimentation is typically defended by arguments that it is reliable, that animals provide sufficiently good models of human biology and diseases to yield relevant information, and that, consequently, its use provides major human health benefits. I demonstrate that a growing body of scientific literature critically assessing the validity of animal experimentation generally (and animal modeling specifically) raises important concerns about its reliability and predictive value for human outcomes and for understanding human physiology. The unreliability of animal experimentation across a wide range of areas undermines scientific arguments in favor of the practice. Additionally, I show how animal experimentation often significantly harms humans through misleading safety studies, potential abandonment of effective therapeutics, and direction of resources away from more effective testing methods. The resulting evidence suggests that the collective harms and costs to humans from animal experimentation outweigh potential benefits and that resources would be better invested in developing human-based testing methods.

The Border Environmental Health Initiative-investigating the transboundary Santa Cruz watershed

Norman, Laura M.; Callegary, James; van Riper, Charles; Gray, Floyd

2010-01-01

In 2004 the U.S. Geological Survey (USGS) launched the Border Environmental Health Initiative (BEHI), a major project encompassing the entire U.S.-Mexico border region. In 2009, a study of the Santa Cruz River Watershed (SCW), located in the border region of Arizona and Sonora, Mexico, was initiated as part of the BEHI. In this borderland region of the desert Southwest, human health and the ecosystems on which humans rely depend critically on limited water resources. Surface water is scarce during much of the year, and groundwater is the primary source for industrial, agricultural, and domestic use. In order to identify risks to water resources in the SCW, and the potential consequences to riparian ecosystems and ultimately human health, the USGS is using an interdisciplinary and integrative approach that incorporates the expertise of geographers, hydrologists, biologists, and geologists to track organic and inorganic contaminants and their effects from sources to sinks in sediment, water, plants, and animals. Existing groundwater and surface-water models are being used and modified to assess contaminant and sediment transport.

Air pollution caused by emissions from industrial and other anthropogenic sources is a long-standing issue for the East Asian region, and will likely remain so in the near future. Being moderately to long-lived, some pollutants survive long-range atmospheric transport and thus are capable of affecting air quality in regions remote to the emission sources. One of problems one may address to quantify this important potential is studying transboundary fluxes of species of interest. Recently the approaches to such problems became more deterministic due to increasingly available data products providing large spatiotemporal coverage, e.g. 3D models and satellite observations. In this study, we quantify the transboundary fluxes of sulphur dioxide (SO2) over the Asian segment of Russian border (shared with Mongolia and China) in 2015. Using the meteorological fields from the ERA INTERIM (EI) re-analysis [1], we calculate the amounts of air transported every 6h in different vertical domains across the border. We reckon that about 5.5•1018 moles of air was transported (net) outwards Russia in the EI-simulated dynamic planetary boundary layer (PBL). We further use the SO2 retrievals products available from the Ozone Monitoring Instrument (OMI, [2]) and the EI data to reconstruct the concomitant mixing ratios of SO2 in the PBL. The convolution of these terms allows to quantify the net transport of SO2 within the PBL, which amounts to not less than (180-190)•103 tons transported inwards Russia in 2015. We find that this result is robust (within ±5•103 tons) when less certain data (e.g. at radiative cloud fraction > 0.2) from OMI PBL SO2 product are included. Similar robustness is seen when the SO2 transport is calculated for the periods when only concomitant satellite data is available (around noon, corresponds to about 17% of total net air transport) and when nearest in time SO2 columns are used for the remaining periods (e.g., night time, about 91% of total net air

Climate politics in the Lower Mekong Basin. National interests and transboundary cooperation on climate change

Energy Technology Data Exchange (ETDEWEB)

Baadsgaard Lange, R.; Moerck Jensen, K.

2013-09-01

Climate change is expected to intensify water security concerns in international river basins. UNFCCC and DAC-donors have been important generators of political attention to the climate agenda among governments in the Mekong Basin in relation to regional cooperation, national policy-making and capacity building. However, the formal commitment to climate action is not necessarily reflected in the everyday business of development. In this paper we use a political economy approach to understand when and how climate change becomes a political priority for the governments of Laos, Thailand and Vietnam, and for transboundary cooperation. Uneven distribution of climate hazards and vulnerabilities create different national risk perceptions and commitment to climate action. Donor funding and national development strategies are also strong drivers of climate action and inaction. Climate change is sometimes used as a scapegoat for domestic policy failures and as a tool to acquire donor funding. We recommend prioritizing climate action in the context of immediate development challenges and 'no regrets' interventions that are likely to enhance adaptive capacity and governments' commitment.

Incorporating in situ habitat patchiness in site selection models reveals that site fidelity is not always a consequence of animal choice.

Science.gov (United States)

Martinez, Aline S; Queiroz, Eduardo V; Bryson, Mitch; Byrne, Maria; Coleman, Ross A

2017-07-01

Understanding site fidelity is important in animal ecology, but evidence is lacking that this behaviour is due to an animal choosing a specific location. To discern site selection behaviour, it is necessary to consider the spatial distribution of habitats that animals can occupy within a landscape. Tracking animals and defining clear habitat boundaries, however, is often difficult. We use in situ habitat distribution data and animal movement simulations to investigate behavioural choice in site fidelity patterns. We resolved the difficulty of gathering data by working with intertidal rock pool systems, which are of manageable size and where boundaries are easy to define. Movements of the intertidal starfish Parvulastra exigua were quantified to test the hypotheses that (1) this species displays fidelity to a particular rock pool and that (2) rock pool fidelity is due to site selection behaviour. Observed patterns of individuals (n = 10 starfish) returning to a previously occupied rock pool (n = 5 pools per location) were tested against an expected null distribution generated through simulations of random movements within their natural patchy environment. Starfish exhibited site selection behaviour at only one location even though site fidelity was high (av. 7·4 starfish out of 10 found in test pools) in two of the three locations. The random chance of a starfish returning to a pool increased 67% for each metre further a rock pool was from the original pool, and 120% for each square metre increase in surface area of an original pool. The decision of returning to an original rock pool was influenced by food availability. When microalgal cover was >60%, there was a c. 50% chance of animals staying faithful to that pool. Our results show the importance to consider spatial distribution of habitats in understanding patterns of animal movement associated with animal choices and site fidelity. Returning to a particular place does not necessarily mean that an animal

The rights of man and animal experimentation.

Science.gov (United States)

Martin, J

1990-01-01

Since emotions give contradictory signals about animal experimentation in medical science, man's relationship to animals must be based upon reason. Thomas Aquinas argues that man is essentially different from animals because man's intellectual processes show evidence of an abstract mechanism not possessed by animals. Man's rights arise in association with this essential difference. The consequence is that only man possesses true rights by Aquinas's definition; animals have them only by analogy. However, cruelty to animals is illicit and they should be protected, principally not because they have rights, but because he who is cruel to animals is more likely to be cruel to his fellowman. If there is a need for animal experimentation in science for the good of man, this approach gives philosophical justification for experimentation, since man's well-being must come before that of animals because of his unique possession of rights. However, those experiments should be carried out in the kindest way possible, to promote kindness towards man. To see man as solely part of a biological continuum in competition for rights with those beings close to him biologically, detracts from man's dignity. PMID:2135948

Andreea-Mihaela Dunca

2018-01-01

Full Text Available This study focuses on water resources management and shows the need to enforce the existing international bilateral agreements and to implement the Water Framework Directive of the European Union in order to improve the water quantity and quality received by a downstream country of a common watershed, like Timiş-Bega hydrographical basin, shared by two countries (Romania and Serbia. The spatial trend of water quality index (WQI and its subindexes are important for determining the locations of major pollutant sources that contribute to water quality depletion in this basin. We compared the values of WQI obtained for 10 sections of the two most important rivers from Banat, which have a great importance for socioeconomic life in southwestern part of Romania and in northeastern part of Serbia. In order to assess the water quality, we calculated the WQI for a long period of time (2004–2014, taking into account the maximum, minimum, and the mean annual values of physical, chemical, and biological parameters (DO, pH, BOD5, temperature, total P, N-NO2−, and turbidity. This article highlights the importance of using the water quality index which has not been sufficiently explored in Romania and for transboundary rivers and which is very useful in improving rivers water quality.

Assessment of transboundary aquifers of the world—vulnerability arising from human water use

International Nuclear Information System (INIS)

Wada, Yoshihide; Heinrich, Lena

2013-01-01

Internationally shared, or transboundary, aquifers (TBAs) have long played an important role in sustaining drinking water supply and food production, supporting livelihoods of millions of people worldwide. Rapidly growing populations and their food demands cast significant doubt on the sustainability of TBAs. Here, this study provides a first quantitative assessment of TBAs worldwide with an aquifer stress indicator over the period 1960–2010 using groundwater abstraction, groundwater recharge, and groundwater contribution to environment flow. The results reveal that 8% of TBAs worldwide are currently stressed due to human overexploitation. Over these TBAs the rate of groundwater pumping increased substantially during the past fifty years, which worsened the aquifer stress condition. In addition, many TBAs over Europe, Asia and Africa are not currently stressed, but their aquifer stress has been increasing at an alarming rate (>100%) for the past fifty years, due to the increasing reliance on groundwater abstraction for food production. Groundwater depletion is substantial over several TBAs including the India River Plain (India, Pakistan), the Paleogene and Cretaceous aquifers (the Arabian Peninsula), and a few TBAs over the USA–Mexico border. Improving irrigation efficiency can reduce the amount of groundwater depletion over some TBAs, but it likely aggravates groundwater depletion over TBAs where conjunctive use of surface water and groundwater is prevalent.

The safety regime concerning transboundary movement of radioactive waste and its compatibility with the trade regime of the WTO

International Nuclear Information System (INIS)

Strack, L.

2004-01-01

There is now extensive international law which regulates or prohibits the transboundary movement of radioactive waste. It seems likely that the trade restrictive provisions of the safety regime could be justified under the scope of Article X XI or X X GATT(general agreement on tariffs and trade). If a legitimate non proliferation issue were involved it is likely that any WTO (world trade organization) dispute settlement organ would allow governments the use of exceptions. Thus, the emerging international radioactive waste regime seems reconcilable under the WTO system. However, further clarification by the political, not the dispute settlement, institutions of the WTO would remove any remaining uncertainty by reaffirming the requirements of current law. Achieving sustainable development requires a coherent framework of global environment and economic governance. (N.C.)

Water Management for Competing Uses: Environmental Flows in the Transboundary Rio Grande/Rio Bravo

Science.gov (United States)

Sandoval Solis, S.; McKinney, D. C.

2011-12-01

Introduction Due to high water demand, the scarcity of water, and the complexity of water allocation, environmental flows have not been considered as an integral part of the water management in the Rio Grande/Rio Bravo transboundary basin. The Big Bend reach is located between the cities of Presidio/Ojinaga to Amistad international reservoir, along the main stream (Fig. 1). Important environmental habitats such as the Big Bend National and State Park in the U.S., the Maderas del Carmen, Cañon de Santa Elena and Ocampo natural reserved areas in Mexico are ecologically threatened because of the lack of environmental water management policies. Several efforts have been undertaken by scientists, government agencies and NGOs to determine the environmental flows for this reach and water management policies that can provide these flows. Objective The objective of this research is to describe a water management policy that can conciliate environmental and human water uses in the Big Bend region. In other words, define a policy that can provide environmental flows without harming water supply for stakeholders or increasing flood risk, within legal and physical constraints of the system. Methodology First, the system was characterized identifying water users, hydraulic infrastructure, and water allocation according to state, federal and international regulations. Second, a hydrograph for environmental flows was proposed that mimics the hydrologic characteristics of the prior dam alteration. Third, a water planning model was constructed to evaluate alternative policies. Fourth, the water management is proposed to provide environmental restoration flows from Luis L. Leon reservoir. This policy considers mechanisms that reduce flooding and drought risks, while meting national and international water regulations. Results Three types of natural flow regimes are considered: (1) median flows aimed to provide the base flow in the region, (2) high flows to provide transversal

This research program performed by Ceramatec may significantly increase the beneficial utilization of fly ash, and improve the overall performance of high quality animal litter products. Ceramatec has developed a novel high surface area material, which is capable of ammonia adsorption. High surface area zeolites when combined with agglomerated fly ash can significantly reduce the use of naturally mined materials (i.e. clay bentonite) for animal litter manufacture. This not only preserves natural resources and the natural environment, but it also will reduce CO₂ emissions, via the reduced need for heavy mining equipment. This novel animal litter is made with over 85% of recycled materials, thus preventing their disposition to landfills. The novel litter material is similar to traditional clay-like litters, and it is clumpable and has superior odor control properties.

Systems engineering applied to integrated safety management for high consequence facilities

1998-01-01

Integrated Safety Management is a concept that is being actively promoted by the U.S. Department of Energy as a means of assuring safe operation of its facilities. The concept involves the integration of safety precepts into work planning rather than adjusting for safe operations after defining the work activity. The system engineering techniques used to design an integrated safety management system for a high consequence research facility are described. An example is given to show how the concepts evolved with the system design

Prions and animal transmissible spongiform encephalopathies

2017-01-01

Full Text Available Background. Transmissible spongiform encephalopathies (TSEs or prion diseases are a unique group of neurodegenerative diseases of animals and humans, which always have a fatal outcome and are transmissible among animals of the same or different species. Scope and Approach. The aim of this work is to review some recent data about animal TSEs, with the emphasis on their causative agents and zoonotic potential, and to discuss why the surveillance and control measures over animal TSEs should remain in force. Key Findings and Conclusions. We still have incomplete knowledge of prions and prion diseases. Scrapie has been present for a very long time and controlled with varied success. Bovine spongiform encephalopathy (BSE emerged unnoticed, and spread within a few years to epidemic proportions, entailing enormous economic consequences and public concerns. Currently, the classical BSE epidemic is under control, but atypical cases do, and probably will, persist in bovine populations. The Chronic Wasting Disease (CWD of the cervids has been spreading in North America and has recently been detected in Europe. Preventive measures for the control of classical BSE remain in force, including the feed ban and removal of specified risk materials. However, active BSE surveillance has considerably decreased. In the absence of such preventive and control measures, atypical BSE cases in healthy slaughtered bovines might persist in the human food chain, and BSE prions might resurface. Moreover, other prion strains might emerge and spread undetected if the appropriate preventive and surveillance measures were to cease, leaving behind inestimable consequences.

Sharing of water of transboundary rivers among riparian nations has become a cause of major concern in different parts of the globe for quite sometime. The issue in the recent decades has been transformed into a source of international tensions and disputes resulting in strained relationships between riparian nations. Conflicts over sharing of water of the international rivers, like the Tigris, Euphrates and Jordan in the Middle East, the Nile in Northern Africa, the Mekong in South-East Asia, the Ganga-Brahmaputra-Meghna in the Indian subcontinent are widely known. The present paper discusses the water sharing -issue in the Ganga- Brahmaputra-Meghna basin located in the Indian sub continent covering five sovereign countries (namely India, Nepal, China, Bhutan and Bangladesh). Rapidly growing population, expanding agricultural and industrial activities besides the impacts of climate change have resulted in stressed condition in the arena of fresh water availability in the basin. Again occurrence of arsenic in sub-surface water in the lower reaches of the basin in India and Bangladesh has also added a new dimension to the problem. All the rivers of the GBM system exhibit wide variations between peak and lean flows as major part of the basin belongs to the monsoon region, where 80%-90 % of annual rainfall is concentrated in 4-5 months of South -West monsoon in the subcontinent. Over and above, the rivers in GBM system carry huge loads of sediments along with the floodwater and receive huge quantum of different kinds of wastes contaminating the water of the rivers. Again high rate of sedimentation of the major rivers and their tributaries have been affecting not only the carrying capacity of the rivers but also drastically reduced their retention capacity. Almost every year during monsoon about 27% and nearly 60% of the GBM basin lying in India and Bangladesh respectively experience flood. The year round navigation in many rivers has also been affected. All these have

The subthalamic nucleus keeps you high on emotion: behavioral consequences of its inactivation

Full Text Available The subthalamic nucleus (STN belongs to the basal ganglia and is the current target for the surgical treatment of neurological and psychiatric disorders such as Parkinson’s Disease (PD and obsessive compulsive disorders, but also a proposed site for the treatment of addiction. It is therefore very important to understand its functions in order to anticipate and prevent possible side-effects in the patients. Although the involvement of the STN is well documented in motor, cognitive and motivational processes, less is known regarding emotional processes. Here we have investigated the direct consequences of STN inactivation by excitotoxic lesions on emotional processing and reinforcement in the rat. We have used various behavioral procedures to assess affect for neutral, positive and negative reinforcers in STN lesioned rats. STN lesions reduced affective responses for positive (sweet solutions and negative (electric foot shock, Lithium Chloride-induced sickness reinforcers while they had no effect on responses for a more neutral reinforcer (novelty induced place preference. Furthermore, when given the choice between saccharine, a sweet but non caloric solution, and glucose, a more bland but caloric solution, in contrast to sham animals that preferred saccharine, STN lesioned animals preferred glucose over saccharine. Taken altogether these results reveal that STN plays a critical role in emotional processing. These results, in line with some clinical observations in PD patients subjected to STN surgery, suggest possible emotional side-effects of treatments targeting the STN. They also suggest that the increased motivation for sucrose previously reported cannot be due to increased pleasure, but could be responsible for the decreased motivation for cocaine reported after STN inactivation.

Sulfur isotopic ratios (δ"3"4S) in size separated aerosol particles (PM2.5 and coarse particles) were measured at Niigata-Maki facing the Sea of Japan. Non-sea salt δ"3"4S (δ"3"4S_n_s_s) in PM2.5 showed seasonal variations with relatively high values in winter (1.0–3.9‰ in spring, 2.8–4.5‰ in summer, 1.3–4.5‰ in autumn, 3.7–5.7‰ in winter). Taking into consideration air mass transport routes, δ"3"4S_n_s_s in the air masses which originated in the Asian continent and were transported over the Sea of Japan to the monitoring sites were higher than those values for air masses which were transported over the Japanese islands after leaving the Asian continent for each season. Considering that the δ"3"4S_n_s_s in sulfuric acid derived from domestic emissions in Japan are lower than those of δ"3"4S_n_s_s in coal, the lower δ"3"4S_n_s_s for the air mass transported over the Japanese islands suggest that sulfuric acid in PM2.5 modified the δ"3"4S_n_s_s due to aerosol mixing with sulfuric acid in Japan. Material balance calculations suggested that the relative contribution of transboundary transport in winter was also higher than for other seasons (40–75% in spring, 51–63% in summer, 45–73% in autumn, and 53–81% in winter). In particular, the contribution to the air masses which were transported directly from the Asian continent was relatively large (75% in spring, 59% in autumn, 78% in winter) in comparison with that for the air masses which were transported over Japan. - Highlights: • δ"3"4Snss in PM2.5 is effective to estimate contribution of anthropogenic sulfur. • δ"3"4Snss have characterized with seasonal variation with high values in winter. • The contribution of transboundary transport is 39-81% at the site facing to the Sea of Japan. • δ"3"4Snss in PM2.5 are modified during transport with mixing of domestic sources. • Map of δ"3"4S distribution originated from coal in Northeast Asia is developed.

Consequences of genetic change in farm animals on food intake and feeding behaviour.

Science.gov (United States)

Emmans, G; Kyriazakis, I

2001-02-01

Selection in commercial populations on aspects of output, such as for growth rate in poultry. against fatness and for growth rate in pigs, and for milk yield in cows, has had very barge effects on such outputs over the past 50 years. Partly because of the cost of recording intake, there has been little or no selection for food intake or feeding behaviour. In order to predict the effects of such past, and future, selection on intake it is necessary to have some suitable theoretical framework. Intake needs to be predicted in order to make rational feeding and environmental decisions. The idea that an animal will eat 'to meet its requirements' has proved useful and continues to be fruitful. An important part of the idea is that the animal (genotype) can be described in a way that is sufficient for the accurate prediction of its outputs over time. Such descriptions can be combined with a set of nutritional constants to calculate requirements. There appears to have been no change in the nutritional constants under selection for output. Under such selection it is simplest to assume that changes in intake follow from the changes in output rates, so that intake changes become entirely predictable. It is suggested that other ways that have been proposed for predicting intake cannot be successful in predicting the effects of selection. Feeding behaviour is seen as being the means that the animal uses to attain its intake rather than being the means by which that intake can be predicted. Thus, the organisation of feeding behaviour can be used to predict neither intake nor the effects of selection on it.

Smileys Without Borders. A Critique of Transboundary Interaction Between Politicians, Journalists and PR Practitioners on Social Media

Directory of Open Access Journals (Sweden)

Peter Berglez

2018-01-01

Full Text Available The purpose of the article is to contribute a critical theoretical understanding of cross-professional relations on social media, focusing on politicians, journalists and PR practitioners. It is well known that these professional groups establish personal and close relations in offline contexts, but more attention needs to be paid to the role of social media. Here, it is argued that, in the context of digital media use, semi-private chatting, humour, and mutual acknowledgement, including the use of likes, smileys, heart symbols, etc. are evidence of a 'neoliberalization' of cross-professional relations. The underlying idea is that the common practice of self-branding undermines representations of professional belonging and exacerbates the blurring of professional boundaries. The critical conceptualization of such 'transboundary' interaction between politicians, journalists and PR practitioners, which is guided by a cultural materialist approach, includes the presentation of examples deriving from the Swedish Twittersphere, and suggestions for empirical research.

Non-invasive and high-sensitivity scanning detection of magnetic nanoparticles in animals using high-Tc scanning superconducting-quantum-interference-device biosusceptometry.

Science.gov (United States)

Chieh, J J; Hong, C Y

2011-08-01

Although magnetic nanoparticles (MNPs) have been widely applied to animals in biomedicine, MNPs within animals should be examined in real time, in vivo, and without bio-damaged possibility to evaluate whether the bio-function of MNPs is valid or to further controls the biomedicinal process because of accompanying complex problems such as MNPs distribution and MNPs biodegradation. The non-invasive and high-sensitivity scanning detection of MNPs in animals using ac susceptometry based on a high-T(c) superconducting quantum interference device (SQUID) is presented. The non-invasive results and biopsy results show good agreement, and two gold-standard biomedicine methods, Prussian blue stain and inductively coupled plasma, prove the magnetic results. This confirms that the future clinical diagnosis of bio-functional MNPs could be operated by using scanning SQUID biosusceptometry as conveniently as an ultrasonic probe.

Mixed-Species Effects on Soil C and N Stocks, C/N Ratio and pH Using a Transboundary Approach in Adjacent Common Garden Douglas-Fir and Beech Stands

Directory of Open Access Journals (Sweden)

Seid Muhie Dawud

2017-03-01

Full Text Available Mixed forest of Douglas-fir and beech has been suggested as one of the possible future forest types in Northwest Europe but the effects of this mixed forest on soil properties relative to monoculture stands are unknown. In a transboundary investigation of adjacent common garden Douglas-fir and beech stands, we determined the effects on topsoil properties. However, responses of C and N stocks, the C/N ratio and pH were site- and soil layer-specific and were mainly single-sided and without synergistic effects. Beech reduced the soil C and N stocks in Douglas-fir at the nutrient-poor site, caused an increase in the C/N ratio in the forest floor and mineral soil at both nutrient-poor and -rich sites, and reduced the acidifying effect of Douglas-fir at the nutrient-poor site. These results do not support the hypothesis that mixture effects would be consistent across sites and soil layers. The lack of synergistic effects may be attributed to the relatively similar litter quality or rooting depth that prevented any larger niche differentiation and complementarity. The results indicate that the transboundary approach within a mature common garden proved useful as a platform to test tree species interactions, and this approach could be explored in soil studies until dedicated mixed-species common gardens reach maturity.

Transmission and epidemiology of zoonotic protozoal diseases of companion animals.

Science.gov (United States)

Esch, Kevin J; Petersen, Christine A

2013-01-01

Over 77 million dogs and 93 million cats share our households in the United States. Multiple studies have demonstrated the importance of pets in their owners' physical and mental health. Given the large number of companion animals in the United States and the proximity and bond of these animals with their owners, understanding and preventing the diseases that these companions bring with them are of paramount importance. Zoonotic protozoal parasites, including toxoplasmosis, Chagas' disease, babesiosis, giardiasis, and leishmaniasis, can cause insidious infections, with asymptomatic animals being capable of transmitting disease. Giardia and Toxoplasma gondii, endemic to the United States, have high prevalences in companion animals. Leishmania and Trypanosoma cruzi are found regionally within the United States. These diseases have lower prevalences but are significant sources of human disease globally and are expanding their companion animal distribution. Thankfully, healthy individuals in the United States are protected by intact immune systems and bolstered by good nutrition, sanitation, and hygiene. Immunocompromised individuals, including the growing number of obese and/or diabetic people, are at a much higher risk of developing zoonoses. Awareness of these often neglected diseases in all health communities is important for protecting pets and owners. To provide this awareness, this review is focused on zoonotic protozoal mechanisms of virulence, epidemiology, and the transmission of pathogens of consequence to pet owners in the United States.

Water resource disputes within transboundary river basin has been hindering the sustainable use of water resources and efficient management of environment. The problem is characterized by a complex information feedback loop that involves socio-economic and environmental systems. This paper presents a system dynamics based model that can simulate the dynamics of water demand, water supply, water adequacy and water allocation instability within a river basin. It was used for a case study in the Zhanghe River basin of China. The base scenario has been investigated for the time period between 2000 and 2050. The result shows that the Chinese national government should change the water allocation scheme of downstream Zhanghe River established in 1989, more water need to be allocated to the downstream cities and the actual allocation should be adjusted to reflect the need associated with the socio-economic and environmental changes within the region, and system dynamics improves the understanding of concepts and system interactions by offering a comprehensive and integrated view of the physical, social, economic, environmental, and political systems.

Principles of animal extrapolation

Energy Technology Data Exchange (ETDEWEB)

Calabrese, E.J.

1991-01-01

Animal Extrapolation presents a comprehensive examination of the scientific issues involved in extrapolating results of animal experiments to human response. This text attempts to present a comprehensive synthesis and analysis of the host of biomedical and toxicological studies of interspecies extrapolation. Calabrese's work presents not only the conceptual basis of interspecies extrapolation, but also illustrates how these principles may be better used in selection of animal experimentation models and in the interpretation of animal experimental results. The book's theme centers around four types of extrapolation: (1) from average animal model to the average human; (2) from small animals to large ones; (3) from high-risk animal to the high risk human; and (4) from high doses of exposure to lower, more realistic, doses. Calabrese attacks the issues of interspecies extrapolation by dealing individually with the factors which contribute to interspecies variability: differences in absorption, intestinal flora, tissue distribution, metabolism, repair mechanisms, and excretion. From this foundation, Calabrese then discusses the heterogeneticity of these same factors in the human population in an attempt to evaluate the representativeness of various animal models in light of interindividual variations. In addition to discussing the question of suitable animal models for specific high-risk groups and specific toxicological endpoints, the author also examines extrapolation questions related to the use of short-term tests to predict long-term human carcinogenicity and birth defects. The book is comprehensive in scope and specific in detail; for those environmental health professions seeking to understand the toxicological models which underlay health risk assessments, Animal Extrapolation is a valuable information source.

The Cooperative Monitoring Center (CMC) promotes collaborations among scientists and researchers in several regions as a means of achieving common regional security objectives. To promote cooperation in South Asia on environmental research, an international working group made up of participants from Bangladesh, India, Nepal, Pakistan, and the United States convened in Kathmandu, Nepal, from February 17-23,2002. The workshop was held to further develop the South Asia Transboundary Water Quality Monitoring (SATWQM) project. The project is sponsored in part by the CMC located at Sandia National Laboratories in Albuquerque, New Mexico through funding provided by the US. Department of State, Regional Environmental Affairs Office, American Embassy, Kathmandu, Nepal, and the National Nuclear Security Administration's (NNSA) Office of Nonproliferation and National Security. This report summarizes the SATWQM project, the workshop objectives, process and results. The long-term interests of the participants are to develop systems for sharing regional environmental information as a means of building confidence and improving relations among South Asian countries. The more immediate interests of the group are focused on activities that foster regional sharing of water quality data in the Ganges and Indus River basins. Issues of concern to the SATWQM network participants include studying the impacts from untreated sewage and industrial effluents, agricultural run-off, salinity increases in fresh waters, the siltation and shifting of river channels, and the environmental degradation of critical habitats such as wetlands, protected forests, and endangered aquatic species conservation areas. The workshop focused on five objectives: (1) a deepened understanding of the partner organizations involved; (2) garnering the support of additional regional and national government and non-government organizations in South Asia involved in river water quality monitoring; (3) identification

An Embedded System for Safe, Secure and Reliable Execution of High Consequence Software

Energy Technology Data Exchange (ETDEWEB)

MCCOY,JAMES A.

2000-08-29

As more complex and functionally diverse requirements are placed on high consequence embedded applications, ensuring safe and secure operation requires an execution environment that is ultra reliable from a system viewpoint. In many cases the safety and security of the system depends upon the reliable cooperation between the hardware and the software to meet real-time system throughput requirements. The selection of a microprocessor and its associated development environment for an embedded application has the most far-reaching effects on the development and production of the system than any other element in the design. The effects of this choice ripple through the remainder of the hardware design and profoundly affect the entire software development process. While state-of-the-art software engineering principles indicate that an object oriented (OO) methodology provides a superior development environment, traditional programming languages available for microprocessors targeted for deeply embedded applications do not directly support OO techniques. Furthermore, the microprocessors themselves do not typically support nor do they enforce an OO environment. This paper describes a system level approach for the design of a microprocessor intended for use in deeply embedded high consequence applications that both supports and enforces an OO execution environment.

The stability of these complex ecological networks largely depends on how predator-prey interactions may respond to temperature changes. Because predators and prey rely on their velocities to catch food or avoid being eaten, understanding how temperatures may affect animal movement is central to this quest. Despite our efforts, we still lack a mechanistic understanding of how the effect of temperature on metabolic processes scales up to animal movement and beyond. Here, we merge a biomechanical approach, the Metabolic Theory of Ecology and empirical data to show that animal movement displays multiple regimes of temperature dependence. We also show that crossing these regimes has important consequences for population dynamics and stability, which depend on the parameters controlling predator-prey interactions. We argue that this dependence upon interaction parameters may help explain why experimental work on the temperature dependence of interaction strengths has so far yielded conflicting results. More importantly, these changes in the temperature dependence of animal movement can have consequences that go well beyond ecological interactions and affect, for example, animal communication, mating, sensory detection, and any behavioral modality dependent on the movement of limbs. Finally, by not taking into account the changes in temperature dependence reported here we might not be able to properly forecast the impact of global warming on ecological processes and propose appropriate mitigation action when needed. © 2016 John Wiley & Sons Ltd.

High in situ repeatability of behaviour indicates animal personality in the beadlet anemone Actinia equina (Cnidaria.

Directory of Open Access Journals (Sweden)

Mark Briffa

Full Text Available 'Animal personality' means that individuals differ from one another in either single behaviours or suites of related behaviours in a way that is consistent over time. It is usually assumed that such consistent individual differences in behaviour are driven by variation in how individuals respond to information about their environment, rather than by differences in external factors such as variation in microhabitat. Since behavioural variation is ubiquitous in nature we might expect 'animal personality' to be present in diverse taxa, including animals with relatively simple nervous systems. We investigated in situ startle responses in a sea anemone, Actinia equina, to determine whether personalities might be present in this example of an animal with a simple nervous system. We found very high levels of repeatability among individuals that were re-identified in the same locations over a three week sampling period. In a subset of the data, where we used tide-pool temperature measurements to control for a key element of variation in microhabitat, these high levels of repeatability remained. Although a range of other consistent differences in micro-habitat features could have contributed to consistent differences between the behaviour of individuals, these data suggest the presence of animal personality in A. equina. Rather than being restricted to certain groups, personality may be a general feature of animals and may be particularly pronounced in species with simple nervous systems.

The review covers the analysis of our own and published data pertaining to population and genetic consequences in various mammalian species under conditions of high levels of ionizing radiation as a result of the Chernobyl accident. The findings indicate that these conditions have promoted the reproduction of heterozygotes in polyloci spectra of molecular genetic markers and animals with a relatively increased stability of the chromosomal apparatus. The prospects of using the reproductive "success" of the carriers of these characteristics as an integral indicator of the selective influence of environmental stress factors are discussed.

2013-11-01

In the past few years, new social passions have sparked on the Chinese mainland. At the centre of these burgeoning passions is a focus on animal welfare, animal treatment, and even animal rights, by the public and academic sectors. With China's rapid economic changes and greater access to information from around the world, societal awareness of animal issues is rising very fast. Hastening this paradigm shift were several highly public incidents involving animal cruelty, including exposés on bear bile harvesting for traditional Chinese medicine, the thousands of dogs rescued from China's meat trade, and the call to boycott shark fin soup and bird nest soup. This article outlines the current status of campaigning by animal advocates in China (specifically the animal rights movement) from three interlinked perspectives: wildlife conservation, companion animal protection, and laboratory animal protection. By reviewing this campaigning, we attempt to present not only the political and social impact of the concept of animal rights, but also the perceptions of, and challenges to, animal rights activities in China. 2013 FRAME.

Currently fresh water scarcity is an issue with huge socio-economic and environmental impacts. Transboundary river and lake basins are among the sources of fresh water facing this challenge. Previous studies measured blue water scarcity at different spatial and temporal resolutions. But there is no global water availability and footprint assessment done at country-basin mesh based spatial and monthly temporal resolutions. In this study we assessed water scarcity at these spatial and temporal resolutions. Our results showed that around 1.6 billion people living within the 328 country-basin units out of the 560 we assessed in this study endures severe water scarcity at least for a month within the year. In addition, 175 country-basin units goes through severe water scarcity for 3-12 months in the year. These sub-basins include nearly a billion people. Generally, the results of this study provide insights regarding the number of people and country-basin units experiencing low, moderate, significant and severe water scarcity at a monthly temporal resolution. These insights might help these basins' sharing countries to design and implement sustainable water management and sharing schemes.

Mechanisms and Consequences of Dopamine Depletion-Induced Attenuation of the Spinophilin/Neurofilament Medium Interaction

Full Text Available Signaling changes that occur in the striatum following the loss of dopamine neurons in the Parkinson disease (PD are poorly understood. While increases in the activity of kinases and decreases in the activity of phosphatases have been observed, the specific consequences of these changes are less well understood. Phosphatases, such as protein phosphatase 1 (PP1, are highly promiscuous and obtain substrate selectivity via targeting proteins. Spinophilin is the major PP1-targeting protein enriched in the postsynaptic density of striatal dendritic spines. Spinophilin association with PP1 is increased concurrent with decreases in PP1 activity in an animal model of PD. Using proteomic-based approaches, we observed dopamine depletion-induced decreases in spinophilin binding to multiple protein classes in the striatum. Specifically, there was a decrease in the association of spinophilin with neurofilament medium (NF-M in dopamine-depleted striatum. Using a heterologous cell line, we determined that spinophilin binding to NF-M required overexpression of the catalytic subunit of protein kinase A and was decreased by cyclin-dependent protein kinase 5. Functionally, we demonstrate that spinophilin can decrease NF-M phosphorylation. Our data determine mechanisms that regulate, and putative consequences of, pathological changes in the association of spinophilin with NF-M that are observed in animal models of PD.

Full Text Available Abstract Background Eating disorders are multifactorial psychiatric disorders. Chronic stressful experiences and caloric restriction are the most powerful triggers of eating disorders in human and animals. Although compulsive behavior is considered to characterize pathological excessive food intake, to our knowledge, no evidence has been reported of continued food seeking/intake despite its possible harmful consequences, an index of compulsive behavior. Brain monoamine transmission is considered to have a key role in vulnerability to eating disorders, and norepinephrine in medial prefrontal cortex has been shown to be critical for food-related motivated behavior. Here, using a new paradigm of conditioned suppression, we investigated whether the ability of a foot-shock-paired conditioned stimulus to suppress chocolate-seeking behavior was reversed by previous exposure to a food restriction experience, thus modeling food seeking in spite of harmful consequences in mice. Moreover, we assessed the effects of selective norepinephrine inactivation in medial prefrontal cortex on conditioned suppression test in stressed and caloric restricted mice. Results While Control (non food deprived animals showed a profound conditioned suppression of chocolate seeking during presentation of conditioned stimulus, previously food restricted animals showed food seeking/intake despite its possible harmful consequences. Moreover, food seeking in spite of harmful consequences was prevented by selective norepinephrine inactivation, thus showing that prefrontal cortical norepinephrine is critical also for maladaptive food-related behavior. Conclusions These findings indicate that adaptive food seeking/intake can be transformed into maladaptive behaviors and point to "top-down" influence on eating disturbances and to new targets for therapy of aberrant eating behaviors.

We investigated whether junior high school students could be educated regarding stroke with an animated cartoon and a Manga that we produced for the purpose of dissemination of this knowledge. We produced a 10-minute animated cartoon and a Manga that provided information regarding stroke risk factors, stroke signs and symptoms, and awareness to immediately contact emergent medical service (EMS) on identification of stroke signs and symptoms. From December 2011 to March 2012, 493 students in 15 classes of the first grade (age 12-13 years) of 3 junior high schools were enrolled in the study. Each subject watched the animated cartoon and read the Manga; this was referred to as "training." Lessons about stroke were not given. Questionnaires on stroke knowledge were evaluated at baseline, immediately after the training, and 3 months after the training. The proportion of correct answers given immediately after the training was higher for all questions, except those related to arrhythmia, compared with baseline. Percentage of correct answers given at 3 months was higher than that at baseline in questions related to facial palsy (75% versus 33%), speech disturbance (91% versus 60%), hemiplegia (79% versus 52%), numbness of 1 side (58% versus 51%), calling for EMS (90% versus 85%), alcohol intake (96% versus 72%), and smoking (69% versus 54%). At 3 months after the training, 56% of students answered the FAST (facial droop, arm weakness, speech disturbance, time to call for EMS) mnemonic correctly. Stroke education using these teaching aids of the animated cartoon and the Manga improved stroke knowledge in junior high school students. Copyright © 2014 National Stroke Association.

Control of Transboundary Movement of Radioactive Material Inadvertently Incorporated into Scrap Metal and Semi-finished Products of the Metal Recycling Industries. Results of the Meetings Conducted to Develop a Draft Code of Conduct

International Nuclear Information System (INIS)

2014-02-01

In 2010, the IAEA initiated the development of a code of conduct on the transboundary movement of radioactive material inadvertently incorporated into scrap metal and semi- finished products of the metal recycling industries (Metal Recycling Code of Conduct). The Metal Recycling Code of Conduct was intended to harmonize the approaches of Member States in relation to the discovery of radioactive material that may inadvertently be present in scrap metals and semi-finished products subject to transboundary movement, and their safe handling and management to facilitate regulatory control. The Metal Recycling Code of Conduct was envisaged as being complementary to the Safety Guide on Control of Orphan Sources and Other Radioactive Material in the Metal Recycling and Production Industries (IAEA Safety Standards Series No. SSG-17), which provides recommendations, principally within a national context, on the protection of workers, members of the public and the environment in relation to the control of radioactive material inadvertently incorporated in scrap metal. In February 2013, the third open-ended meeting of technical and legal experts to develop the Metal Recycling Code of Conduct was organized. The objective of this meeting was to address the comments received from Member States and to finalize the text of the draft Metal Recycling Code of Conduct. Representatives from 55 Member States, one non-Member State and the EU, together with seven observers from the metal recycling industry, reviewed the comments and revised the draft accordingly. In September 2013, in Resolution GC(57)/RES/9, the IAEA General Conference recorded that it 'Appreciates the intensive efforts undertaken by the Secretariat to develop a code of conduct on the transboundary movement of scrap metal, or materials produced from scrap metal, that may inadvertently contain radioactive material, and encourages the Secretariat to make the results of the discussion conducted on this issue available to

First application of liquid-metal-jet sources for small-animal imaging: High-resolution CT and phase-contrast tumor demarcation

Larsson, Daniel H.; Lundstroem, Ulf; Burvall, Anna; Hertz, Hans M.

Purpose: Small-animal studies require images with high spatial resolution and high contrast due to the small scale of the structures. X-ray imaging systems for small animals are often limited by the microfocus source. Here, the authors investigate the applicability of liquid-metal-jet x-ray sources for such high-resolution small-animal imaging, both in tomography based on absorption and in soft-tissue tumor imaging based on in-line phase contrast. Methods: The experimental arrangement consists of a liquid-metal-jet x-ray source, the small-animal object on a rotating stage, and an imaging detector. The source-to-object and object-to-detector distances are adjusted for the preferred contrast mechanism. Two different liquid-metal-jet sources are used, one circulating a Ga/In/Sn alloy and the other an In/Ga alloy for higher penetration through thick tissue. Both sources are operated at 40-50 W electron-beam power with {approx}7 {mu}m x-ray spots, providing high spatial resolution in absorption imaging and high spatial coherence for the phase-contrast imaging. Results: High-resolution absorption imaging is demonstrated on mice with CT, showing 50 {mu}m bone details in the reconstructed slices. High-resolution phase-contrast soft-tissue imaging shows clear demarcation of mm-sized tumors at much lower dose than is required in absorption. Conclusions: This is the first application of liquid-metal-jet x-ray sources for whole-body small-animal x-ray imaging. In absorption, the method allows high-resolution tomographic skeletal imaging with potential for significantly shorter exposure times due to the power scalability of liquid-metal-jet sources. In phase contrast, the authors use a simple in-line arrangement to show distinct tumor demarcation of few-mm-sized tumors. This is, to their knowledge, the first small-animal tumor visualization with a laboratory phase-contrast system.

Despite the clear fitness consequences of animal decisions, the science of animal decision making in evolutionary biology is underdeveloped compared with decision science in human psychology. Specifically, the field lacks a conceptual framework that defines and describes the relevant components of a decision, leading to imprecise language and concepts. The 'judgment and decision-making' (JDM) framework in human psychology is a powerful tool for framing and understanding human decisions, and we apply it here to components of animal decisions, which we refer to as 'cognitive phenotypes'. We distinguish multiple cognitive phenotypes in the context of a JDM framework and highlight empirical approaches to characterize them as evolvable traits. Copyright © 2016 Elsevier Ltd.

ANIMAL BEHAVIOR AND WELL-BEING SYMPOSIUM: Interaction between coping style/personality, stress, and welfare: Relevance for domestic farm animals.

Science.gov (United States)

Koolhaas, J M; Van Reenen, C G

2016-06-01

This paper will argue that understanding animal welfare and the individual vulnerability to stress-related disease requires a fundamental understanding of functional individual variation as it occurs in nature as well as the underlying neurobiology and neuroendocrinology. Ecological studies in feral populations of mice, fish, and birds start to recognize the functional significance of phenotypes that individually differ in their behavioral and neuroendocrine response to environmental challenge. Recent studies indicate that the individual variation within a species may buffer the species for strong fluctuations in the natural habitat. Similarly, evolutionary ancient behavioral trait characteristics have now been identified in a range of domestic farm animals including cattle, pigs, and horses. Individual variation in behavior can be summarized in a 3-dimensional model with coping style, emotionality, and sociality as independent dimensions. These dimensions can be considered trait characteristics that are stable over time and across situations within the individual. This conceptual model has several consequences. First, the coping style dimension is strongly associated with differential stress vulnerability. Social stress studies show that proactive individuals are resilient under stable environmental conditions but vulnerable when outcome expectancies are violated. Reactive individuals are, in fact, rather flexible and seem to adapt more easily to a changing environment. A second consequence relates to genetics and breeding. Genetic selection for one trait usually implies selection for other traits as well. It is discussed that a more balanced breeding program that takes into account biologically functional temperamental traits will lead to more robust domestic farm animals. Finally, the relationship between temperamental traits, animal production, fitness, and welfare is discussed.

Unreliability and the Animal Narrator in Richard Adams’s The Plague Dogs

Directory of Open Access Journals (Sweden)

Anja Höing

2017-03-01

Full Text Available Richard Adams’s talking animal story The Plague Dogs (1978, with its deeply genre-atypical mode of narration, offers a multiplicity of avenues to explore the literary animal as animal. The story draws much of its power from the psychological complexity and related unreliability of both canine narrators, two research lab escapees gone feral. Both the terrier Snitter and the black mongrel Rowf are mentally ill and experience a highly subjective, part-fantastic world. In episodes of zero focalization, a sarcastic voice comments on the plot from the off, aggressively attacking a thoroughly anthropocentric superstructure the protagonists themselves are oblivious of, and presenting all that is normally constructed as “rational” in the implied reader’s world as a carnivalesque farce. Combining these equally unreliable narratives, The Plague Dogs creates a unique mixture of what Phelan (2007 calls “estranging” and “bonding” unreliability and brings to light the devastating consequences of anthropocentrism. The Plague Dogs not only defamiliarizes a genre usually committed to conventional means of storytelling, but the dominant Western conception of the status of animals in the world, showing that once we start to read the animal as animal, this sets into motion an avalanche of other concepts in need of re-reading, among them the very ones making up the fundamental pillars of Western societies’ anthropocentric self-conception.

The missions of the World Organisation for Animal Health (OIE) include the design of surveillance and control methods for infectious transboundary animal diseases (including zoonoses), the provision of guarantees concerning animal health and animal production food safety, and the setting of standards for, and promotion of, animal welfare. The OIE role in setting standards for the sanitary safety of international trade in animals and animal products is formally recognised in the World Trade Organization (WTO) Agreement on the Application of Sanitary and Phytosanitary Measures (the SPS Agreement). While the primary focus of the OIE is on animal diseases and zoonoses, the OIE has also been working within the WTO framework to examine possible contributions the organisation can make to achieving the goals of the Convention on Biological Diversity, particularly to preventing the global spread of invasive alien species (IAS). However, at the present time, setting standards for invasive species (other than those connected to the cause and distribution of diseases listed by the OIE) is outside the OIE mandate. Any future expansion of the OIE mandate would need to be decided by its Members and resources (expertise and financial contributions) for an extended standard-setting work programme secured. The other international standard-setting organisations referenced by the SPS Agreement are the International Plant Protection Convention (IPPC) and the Codex Alimentarius Commission (CAC). The IPPC mandate and work programme address IAS and the protection of biodiversity. The CAC is not involved in this field.

This article gives an overview of the World Organisation for Animal Health (OIE) Worldwide Animal Disease Notification System and highlights the major achievements during the past decade. It describes the different types of disease notification reports received and processed by the OIE. It also evaluates the three strategies implemented by the OIE in the recent years aimed at improving disease notification: introduction and use of a secure online notification system World Animal Health Information System (WAHIS) and its database interface World Animal Health Information Database (WAHID); implementation of active search and verification procedures for non-official information; and enhanced building of capacity for animal disease notification to the OIE by Members Countries. The improvements are evidenced by the increasing number of reports submitted on an annual basis and the reduction in submission time together with an improvement in the quality and quantity of the immediate notifications and follow-up reports, six-monthly and annual reports submitted by Veterinary Authorities. In the recent years, the OIE's notification system provides an early warning system more sensitive and global. Consequently, there is a greater knowledge of animal diseases' distribution worldwide. As a result, it is possible to ensure better prevention, more accurate risk assessment and evaluation by diminishing the spread of known or newly emerging pathogens. Copyright © 2012 Elsevier B.V.

Subfreezing temperatures, low light levels, and high doses of ionizing and ultraviolet radiation extending for many months after a large-scale nuclear war could destroy the biological support systems of civilization, at least in the Northern Hemisphere. Productivity in natural and agricultural ecosystems could be severely restricted for a year or more. Postwar survivors would face starvation as well as freezing conditions in the dark and be exposed to near-lethal doses of radiation. If, as now seems possible, the Southern Hemisphere were affected also, global disruption of the biosphere could ensue. In any event, there would be severe consequences, even in the areas not affected directly, because of the interdependence of the world economy. In either case the extinction of a large fraction of the Earth's animals, plants, and microorganisms seems possible. The population size of Homo sapiens conceivably could be reduced to prehistoric levels or below, and extinction of the human species itself cannot be excluded.

Intrauterine hypoxia can occur in pregnant women living at high altitude and/or with cardiovascular disease. In addition, placental hypoxia can be generated by altered placental development and spiral artery remodeling leading to placental insufficiency and dysfunction. Both conditions can impact normal maternal cardiovascular homeostasis leading to preeclampsia and/or impair transfer of O2/nutrient supply resulting in fetal growth restriction. This review discusses the mechanisms underlying altered placental vessel remodeling, maternal and fetal consequences, patient management, and potential future therapies for improving these conditions.

Positive and negative affects high in motivational intensity cause a narrowing of attentional focus. In contrast, positive affects low in motivational intensity cause a broadening of attentional focus. The attentional consequences of negative affects low in motivational intensity have not been experimentally investigated. Experiment 1 compared the attentional consequences of negative affect low in motivational intensity (sadness) relative to a neutral affective state. Results indicated that low-motivation negative affect caused attentional broadening. Experiment 2 found that disgust, a high-motivation negative affect not previously investigated in attentional studies, narrowed attentional focus. These experiments support the conceptual model linking high-motivation affective states to narrowed attention and low-motivation affective states to broadened attention.

Concepts of animal welfare in relation to positions in animal ethics.

Science.gov (United States)

Schmidt, Kirsten

2011-06-01

When animal ethicists deal with welfare they seem to face a dilemma: On the one hand, they recognize the necessity of welfare concepts for their ethical approaches. On the other hand, many animal ethicists do not want to be considered reformist welfarists. Moreover, animal welfare scientists may feel pressed by moral demands for a fundamental change in our attitude towards animals. The analysis of this conflict from the perspective of animal ethics shows that animal welfare science and animal ethics highly depend on each other. Welfare concepts are indispensable in the whole field of animal ethics. Evidence for this can be found by analyzing the structure of theories of animal ethics and the different ways in which these theories employ welfare concepts. Furthermore, the background of values underneath every welfare theory is essential to pursue animal welfare science. Animal ethics can make important contributions to the clarification of underlying normative assumptions with regard to the value of the animal, with regard to ideas about what is valuable for the animal, and with regard to the actions that should follow from the results of animal welfare science.

We found a significant geographic gradient (longitudinal and latitudinal) in the sulfate (SO 42-) concentrations measured at multiple sites over the East Asian Pacific Rim region. Furthermore, the observed gradient was well reproduced by a regional chemical transport model. The observed and modeled SO 42- concentrations were higher at the sites closer to the Asian continent. The concentrations of SO 42- from China as calculated by the model also showed the fundamental features of the longitudinal/latitudinal gradient. The proportional contribution of Chinese SO 42- to the total in Japan throughout the year was above 50-70% in the control case, using data for Chinese sulfur dioxide (SO 2) emission from the Regional Emission Inventory in Asia (40-60% in the low Chinese emissions case, using Chinese SO 2 emissions data from the State Environmental Protection Administration of China), with a winter maximum of approximately 65-80%, although the actual concentrations of SO 42- from China were highest in summer. The multiple-site measurements and the model analysis strongly suggest that the SO 42- concentrations in Japan were influenced by the outflow from the Asian continent, and this influence was greatest in the areas closer to the Asian continent. In contrast, we found no longitudinal/latitudinal gradient in SO 2 concentrations; instead SO 2 concentrations were significantly correlated with local SO 2 emissions. Our results show that large amounts of particulate sulfate are transported over long distances from the East Asian Pacific Rim region, and consequently the SO 42- concentrations in Japan are controlled by the transboundary outflow from the Asian continent.

The challenges and opportunities of transboundary cooperation through the lens of the East Carpathians Biosphere Reserve

Full Text Available A significant challenge of our time is conserving biological diversity while maintaining economic development and cultural values. The United Nations Educational, Scientific and Cultural Organization has established biosphere reserves within its Man and the Biosphere program as a model means for accomplishing this very challenge. The East Carpathians Biosphere Reserve (ECBR, spreading across Poland, Slovakia, and Ukraine, represents a large social-ecological system (SES that has been protected under the biosphere reserve designation since 1998. We have explored its successes and failures in improving human livelihoods while safeguarding its ecosystems. The SES framework, which includes governance system, actors, resources, and external influences, was used as a frame of analysis. The outcomes of this protected area have been mixed; its creation led to national and international collaboration, yet some actor groups remain excluded. Implementation of protocols arising from the Carpathian Convention has been slow, while deforestation, hunting, erosion, temperature extremes, and changes in species behavior remain significant threats but have also been factors in ecological adaptation. The loss of cultural links and traditional knowledge has also been significant. Nevertheless, this remains a highly biodiverse area. Political barriers and institutional blockages will have to be removed to ensure this reserve fulfills its role as a model region for international collaboration and capacity building. These insights drawn from the ECBR demonstrate that biosphere reserves are indeed learning sites for sustainable development and that this case is exemplary in illustrating the challenges, but more importantly, the opportunities that arise when ensuring parallel care and respect for people and ecosystems through the model of transboundary protected areas around the world.

High-consequence analysis, evaluation, and application of select criteria

Gutmanis, I.; Jaksch, J.A.

1984-01-01

A number of characteristics distinguish environmental risk from pollution problems. The characteristics make environmental risk problems harder to manage through existing regulatory, legal, and economic institutions. Hence, technologies involving environmental risk impose on society extremely difficult collective decisions. This paper is concerned with the process of reaching social decisions that involve low-probability, high-consequence outcomes. It is divided into five major parts. Part I contains the introduction. Part II reviews the two main classes of criteria that have been proposed for social decisions: approaches based on market mechanisms and their extension, and approaches associated with Rawls and Buchanan, which not only focus on outcomes, but also impose a set of minimal constraints on the process for reaching decisions and social consensus. Part III proposes a set of eight criteria for evaluating social decision processes. In Parts IV and V we investigate applying the criteria to two case studies -- one on nuclear waste disposal and the other on transportation of liquefied natural gas

Public perceptions of animal experimentation across Europe.

von Roten, Fabienne Crettaz

2013-08-01

The goal of this article is to map out public perceptions of animal experimentation in 28 European countries. Postulating cross-cultural differences, this study mixes country-level variables (from the Eurostat database) and individual-level variables (from Eurobarometer Science and Technology 2010). It is shown that experimentation on animals such as mice is generally accepted in European countries, but perceptions are divided on dogs and monkeys. Between 2005 and 2010, we observe globally a change of approval on dogs and monkeys, with a significant decrease in nine countries. Multilevel analysis results show differences at country level (related to a post-industrialism model) and at individual level (related to gender, age, education, proximity and perceptions of science and the environment). These results may have consequences for public perceptions of science and we call for more cross-cultural research on press coverage of animal research and on the level of public engagement of scientists doing animal research.

Cool roofs with high solar reflectance for the welfare of dairy farming animals

Santunione, G.; Libbra, A.; Muscio, A.

2017-01-01

Ensuring livestock welfare in dairy farming promotes the production capacity of the animals in terms of both quantity and quality. In welfare conditions, the animals can produce at their full potential. For the dairy cattle the most debilitating period of the year is summer, when the stress arising from overheating induces physiological alterations that compromise the animals’ productivity. In this study, the summer discomfort of dairy animals is primarily quantified and the production loss is quantified versus the Temperature Humidity Index (THI), which correlates the values of temperature and relative humidity to the thermal stress. In order to reduce or eliminate such thermal stress, it is then proposed to coat the roof of the stables with a paint having high solar reflectance and thermal emittance, that is a cool roof product. This type of roofing solution can considerably limit the overheating of stables caused by solar radiation, thus providing a positive impact on the animals’ welfare and improving significantly their productivity in summer.

Ensuring livestock welfare in dairy farming promotes the production capacity of the animals in terms of both quantity and quality. In welfare conditions, the animals can produce at their full potential. For the dairy cattle the most debilitating period of the year is summer, when the stress arising from overheating induces physiological alterations that compromise the animals’ productivity. In this study, the summer discomfort of dairy animals is primarily quantified and the production loss is quantified versus the Temperature Humidity Index (THI), which correlates the values of temperature and relative humidity to the thermal stress. In order to reduce or eliminate such thermal stress, it is then proposed to coat the roof of the stables with a paint having high solar reflectance and thermal emittance, that is a cool roof product. This type of roofing solution can considerably limit the overheating of stables caused by solar radiation, thus providing a positive impact on the animals’ welfare and improving significantly their productivity in summer.

Prison-based animal programs have shown promise when it comes to increased sociability, responsibility, and levels of patience for inmates who participate in these programs. Yet there remains a dearth of scientific research that demonstrates the impact of prison-based animal programs on inmates' physical and mental health. Trials of animal-assisted therapy interventions, a form of human-animal interaction therapy most often used with populations affected by depression/anxiety, mental illness, and trauma, may provide models of how prison-based animal program research can have widespread implementation in jail and prison settings, whose populations have high rates of mental health problems. This paper reviews the components of prison-based animal programs most commonly practiced in prisons today, presents five animal-assisted therapy case studies, evaluates them based on their adaptability to prison-based animal programs, and discusses the institutional constraints that act as barriers for rigorous prison-based animal program research implementation. This paper can serve to inform the development of a research approach to animal-assisted therapy that nurses and other public health researchers can use in working with correctional populations. © 2016 Wiley Periodicals, Inc.

Embodied crop calories in animal products

2013-01-01

Increases in animal products consumption and the associated environmental consequences have been a matter of scientific debate for decades. Consequences of such increases include rises in greenhouse gas emissions, growth of consumptive water use, and perturbation of global nutrients cycles. These consequences vary spatially depending on livestock types, their densities and their production system. In this letter, we investigate the spatial distribution of embodied crop calories in animal products. On a global scale, about 40% of the global crop calories are used as livestock feed (we refer to this ratio as crop balance for livestock) and about 4 kcal of crop products are used to generate 1 kcal of animal products (embodied crop calories of around 4). However, these values vary greatly around the world. In some regions, more than 100% of the crops produced is required to feed livestock requiring national or international trade to meet the deficit in livestock feed. Embodied crop calories vary between less than 1 for 20% of the livestock raising areas worldwide and greater than 10 for another 20% of the regions. Low values of embodied crop calories are related to production systems for ruminants based on fodder and forage, while large values are usually associated with production systems for non-ruminants fed on crop products. Additionally, we project the future feed demand considering three scenarios: (a) population growth, (b) population growth and changes in human dietary patterns and (c) changes in population, dietary patterns and feed conversion efficiency. When considering dietary changes, we project the global feed demand to be almost doubled (1.8–2.3 times) by 2050 compared to 2000, which would force us to produce almost equal or even more crops to raise our livestock than to directly nourish ourselves in the future. Feed demand is expected to increase over proportionally in Africa, South-Eastern Asia and Southern Asia, putting additional stress on

Consequences of low dose ionizing radiation exposure on the hippocampal microenvironment.

Directory of Open Access Journals (Sweden)

Munjal M Acharya

Full Text Available The response of the brain to irradiation is complex, involving a multitude of stress inducible pathways that regulate neurotransmission within a dynamic microenvironment. While significant past work has detailed the consequences of CNS radiotherapy following relatively high doses (≥ 45 Gy, few studies have been conducted at much lower doses (≤ 2 Gy, where the response of the CNS (like many other tissues may differ substantially from that expected from linear extrapolations of high dose data. Low dose exposure could elicit radioadaptive modulation of critical CNS processes such as neurogenesis, that provide cellular input into hippocampal circuits known to impact learning and memory. Here we show that mice deficient for chemokine signaling through genetic disruption of the CCR2 receptor exhibit a neuroprotective phenotype. Compared to wild type (WT animals, CCR2 deficiency spared reductions in hippocampal neural progenitor cell survival and stabilized neurogenesis following exposure to low dose irradiation. While radiation-induced changes in microglia levels were not found in WT or CCR2 deficient animals, the number of Iba1+ cells did differ between each genotype at the higher dosing paradigms, suggesting that blockade of this signaling axis could moderate the neuroinflammatory response. Interestingly, changes in proinflammatory gene expression were limited in WT animals, while irradiation caused significant elevations in these markers that were attenuated significantly after radioadaptive dosing paradigms in CCR2 deficient mice. These data point to the importance of chemokine signaling under low dose paradigms, findings of potential significance to those exposed to ionizing radiation under a variety of occupational and/or medical scenarios.

Full Text Available Following legislation, European Member States should have multi-annual control programs for contaminants, such as for mycotoxins, in feed and food. These programs need to be risk based implying the checks are regular and proportional to the estimated risk for animal and human health. This study aimed to prioritize feed products in the Netherlands for deoxynivalenol and aflatoxin B1 monitoring. Historical mycotoxin monitoring results from the period 2007–2016 were combined with data from other sources. Based on occurrence, groundnuts had high priority for aflatoxin B1 monitoring; some feed materials (maize and maize products and several oil seed products and complete/complementary feed excluding dairy cattle and young animals had medium priority; and all other animal feeds and feed materials had low priority. For deoxynivalenol, maize by-products had a high priority, complete and complementary feed for pigs had a medium priority and all other feed and feed materials a low priority. Also including health consequence estimations showed that feed materials that ranked highest for aflatoxin B1 included sunflower seed and palmkernel expeller/extracts and maize. For deoxynivalenol, maize products were ranked highest, followed by various small grain cereals (products; all other feed materials were of lower concern. Results of this study have proven to be useful in setting up the annual risk based control program for mycotoxins in animal feed and feed materials.

Monitoring residue in animals and primary products of animal origin

2008-01-01

Full Text Available The objective of control and systematic monitoring of residue is to secure, by the examination of a corresponding number of samples, the efficient monitoring of the residue level in tissues and organs of animals, as well as in primary products of animal origin. This creates possibilities for the timely taking of measures toward the securing of food hygiene of animal origin and the protection of public health. Residue can be a consequence of the inadequate use of medicines in veterinary medicine and pesticides in agriculture and veterinary medicine, as well as the polluting of the environment with toxic elements, dioxins, polychlorinated biphenyls, and others. Residue is being monitored in Serbia since 1972, and in 2004, national monitoring was brought to the level of EU countries through significant investments by the Ministry of Agriculture, Forestry and Water Management. This is also evident in the EU directives which permit exports of all kinds of meat and primary products of animal origin, covered by the Residue Monitoring Program. The program of systematic examinations of residue has been coordinated with the requirements of the European Union, both according to the type of examined substance, as well as according to the number of samples and the applied analytical techniques. In addition to the development of methods and the including of new harmful substances into the monitoring programme, it is also necessary to coordinate the national regulations that define the maximum permitted quantities of certain medicines and contaminants with the EU regulations, in order to protect the health of consumers as efficiently as possible, and for the country to take equal part in international trade.

Phenomenological consequences of supersymmetry

This paper deals with the phenomenological consequences of supersymmetric theories, and with the implications of such theories for future high energy machines. The paper represents the work of a subgroup at the meeting. The authors are concerned only with high energy predictions of supersymmetry; low energy consequences (for example in the K/sub o/K-bar/sub o/ system) are discussed in the context of future experiments by another group, and will be mentioned briefly only in the context of constraining existing models. However a brief section is included on the implication for proton decay, although detailed experimental questions are not discussed

Consequences of evolution: is rhinosinusitis, like otitis media, a unique disease of humans?

Science.gov (United States)

Bluestone, Charles D; Pagano, Anthony S; Swarts, J Douglas; Laitman, Jeffrey T

2012-12-01

We hypothesize that if otitis media is most likely primarily a human disease due to consequences of evolution, rhinosinusitis may also be limited to humans for similar reasons. If otitis media, with its associated hearing loss, occurred in animals in the wild, they probably would have been culled out by predation. Similarly, if rhinosinusitis occurred regularly in animals, they likely would have suffered from severely decreased olfactory abilities, crucial for predator avoidance, and presumably would likewise have been selected against evolutionarily. Thus, both otitis media and rhinosinusitis-common conditions particularly in infants and young children-appear to be essentially human conditions. Their manifestation in our species is likely due to our unique evolutionary trajectory and may be a consequence of adaptations, including adaptations to bipedalism and speech, loss of prognathism, and immunologic and environmental factors.

The transportation of poultry and related products for international trade contributes to transboundary pathogen spread and disease outbreaks worldwide. To prevent pathogen incursion through poultry products, many countries have regulations about animal health and poultry product quarantine. However, in Japan, animal products have been illegally introduced into the country in baggage and confiscated at the airport. Lately, the number of illegally imported poultry and the incursion risk of transboundary pathogens through poultry products have been increasing. In this study, we isolated avian influenza viruses (AIVs) from raw poultry products illegally imported to Japan by international passengers. Highly (H5N1 and H5N6) and low (H9N2 and H1N2) pathogenic AIVs were isolated from raw chicken and duck products carried by flight passengers. H5 and H9 isolates were phylogenetically closely related to viruses isolated from poultry in China, and haemagglutinin genes of H5N1 and H5N6 isolates belonged to clades 2.3.2.1c and 2.3.4.4, respectively. Experimental infections of H5 and H9 isolates in chickens and ducks demonstrated pathogenicity and tissue tropism to skeletal muscles. To prevent virus incursion by poultry products, it is important to encourage the phased cleaning based on the disease control and eradication and promote the reduction in contamination risk in animal products. © 2017 Blackwell Verlag GmbH.

How animals move: comparative lessons on animal locomotion.

Science.gov (United States)

Schaeffer, Paul J; Lindstedt, Stan L

2013-01-01

Comparative physiology often provides unique insights in animal structure and function. It is specifically through this lens that we discuss the fundamental properties of skeletal muscle and animal locomotion, incorporating variation in body size and evolved difference among species. For example, muscle frequencies in vivo are highly constrained by body size, which apparently tunes muscle use to maximize recovery of elastic recoil potential energy. Secondary to this constraint, there is an expected linking of skeletal muscle structural and functional properties. Muscle is relatively simple structurally, but by changing proportions of the few muscle components, a diverse range of functional outputs is possible. Thus, there is a consistent and predictable relation between muscle function and myocyte composition that illuminates animal locomotion. When animals move, the mechanical properties of muscle diverge from the static textbook force-velocity relations described by A. V. Hill, as recovery of elastic potential energy together with force and power enhancement with activation during stretch combine to modulate performance. These relations are best understood through the tool of work loops. Also, when animals move, locomotion is often conveniently categorized energetically. Burst locomotion is typified by high-power outputs and short durations while sustained, cyclic, locomotion engages a smaller fraction of the muscle tissue, yielding lower force and power. However, closer examination reveals that rather than a dichotomy, energetics of locomotion is a continuum. There is a remarkably predictable relationship between duration of activity and peak sustainable performance.

Diagnosis of esophageal disorders in carnivorous animals

International Nuclear Information System (INIS)

Fenyves, B.; Korodi, P.

1997-01-01

The esophagus serves to carry food, water and saliva from the pharynx to the stomach. Interruption of this function results in severe consequences for the animal, and complications of the esophageal disorders (e.g. pneumonia, mediastinitis, pleuritis, pyothorax, pneumothorax) can cause similarly serious problems. Clinical signs of esophageal disorders are similar to that of other gastrointestinal diseases. Diagnosis (based on the patient's medical history and clinical signs) is confirmed by supplementary examination. Radiology, possibly including contrast studies, is the primary in the home practice in consequence of the limited financial possibilities. The article reviews radiology, complications, prognosis and some treatment methods of esophageal disorders

Statistics of Scientific Procedures on Living Animals 2014: A new format, and hopefully a new era of diminishing animal experimentation?

2016-03-01

The Annual Statistics of Scientific Procedures on Living Animals Great Britain 2014 reports a welcome decline in animal experimentation in the UK. However, caution has to be exercised when interpreting these most recent figures, due to the significant changes made to satisfy the requirements of Directive 2010/63/EU as to what information is reported and how it is reported. Comparisons to the figures and trends reported in previous years is difficult, so this paper focuses on the specifics of the current report, providing information on overall animal use and highlighting specific issues associated with genetically-altered animals, fish and primates. There is a detailed discussion of the extent of the changes, commenting on the benefits and disadvantages of the new format, in areas such as severity of procedures, legislation and techniques of special interest. It also considers the consequences of the changes on the effective monitoring of laboratory animal use, the openness and transparency regarding the impacts of animal use, and the implementation of Three Rs initiatives. In addition, suggestions for further improvements to the new format are made to the Home Office. 2016 FRAME.

Optogenetics in animal model of alcohol addiction

Nalberczak, Maria; Radwanska, Kasia

2014-11-01

Our understanding of the neuronal and molecular basis of alcohol addiction is still not satisfactory. As a consequence we still miss successful therapy of alcoholism. One of the reasons for such state is the lack of appropriate animal models which would allow in-depth analysis of biological basis of addiction. Here we will present our efforts to create the animal model of alcohol addiction in the automated learning device, the IntelliCage setup. Applying this model to optogenetically modified mice with remotely controlled regulation of selected neuronal populations by light may lead to very precise identification of neuronal circuits involved in coding addiction-related behaviors.

Transboundary health impacts of transported global air pollution and international trade

Tong, D.; Zhang, Q.; Jiang, X.

2017-12-01

Millions of people die every year from diseases caused by exposure to outdoor air pollution. Some studies have estimated premature mortality related to local sources of air pollution, but local air quality can also be affected by atmospheric transport of pollution from distant sources. International trade is contributing to the globalization of emission and pollution as a result of the production of goods (and their associated emissions) in one region for consumption in another region. The effects of international trade on air pollutant emissions, air quality and health have been investigated regionally, but a combined, global assessment of the health impacts related to international trade and the transport of atmospheric air pollution is lacking. Here we combine four global models to estimate premature mortality caused by fine particulate matter (PM2.5) pollution as a result of atmospheric transport and the production and consumption of goods and services in different world regions. We find that, of the 3.45 million premature deaths related to PM2.5 pollution in 2007 worldwide, about 12 per cent (411,100 deaths) were related to air pollutants emitted in a region of the world other than that in which the death occurred, and about 22 per cent (762,400 deaths) were associated with goods and services produced in one region for consumption in another. For example, PM2.5 pollution produced in China in 2007 is linked to more than 64,800 premature deaths in regions other than China, including more than 3,100 premature deaths in western Europe and the USA; on the other hand, consumption in western Europe and the USA is linked to more than 108,600 premature deaths in China. Our results reveal that the transboundary health impacts of PM2.5 pollution associated with international trade are greater than those associated with long-distance atmospheric pollutant transport.

[Reduction of animal experiments in experimental drug testing].

Science.gov (United States)

Behrensdorf-Nicol, H; Krämer, B

2014-10-01

In order to ensure the quality of biomedical products, an experimental test for every single manufactured batch is required for many products. Especially in vaccine testing, animal experiments are traditionally used for this purpose. For example, efficacy is often determined via challenge experiments in laboratory animals. Safety tests of vaccine batches are also mostly performed using laboratory animals. However, many animal experiments have clear inherent disadvantages (low accuracy, questionable transferability to humans, unclear significance). Furthermore, for ethical reasons and animal welfare aspects animal experiments are also seen very critical by the public. Therefore, there is a strong trend towards replacing animal experiments with methods in which no animals are used ("replacement"). If a replacement is not possible, the required animal experiments should be improved in order to minimize the number of animals necessary ("reduction") and to reduce pain and suffering caused by the experiment to a minimum ("refinement"). This "3R concept" is meanwhile firmly established in legislature. In recent years many mandatory animal experiments have been replaced by alternative in vitro methods or improved according to the 3R principles; numerous alternative methods are currently under development. Nevertheless, the process from the development of a new method to its legal implementation takes a long time. Therefore, supplementary regulatory measures to facilitate validation and acceptance of new alternative methods could contribute to a faster and more consequent implementation of the 3R concept in the testing of biomedical products.

Consequences in Norway after a hypothetical accident at Sellafield - Predicted impacts on the environment

Thoerring, H.; Ytre-Eide, M.A.; Liland, A.

2010-12-01

This report describes the possible environmental consequences for Norway due to a hypothetical accident at the Sellafield complex in the UK. The scenario considered involves an explosion and fire at the B215 facility resulting in a 1 % release of the total HAL (Highly Active liquor) inventory of radioactive waste with a subsequent air transport and deposition in Norway. Air transport modelling is based on real meteorological data from October 2008 with wind direction towards Norway and heavy precipitation. This weather is considered to be quite representative as typical seasonal weather. Based on this weather scenario, the estimated fallout in Norway will be ∼ 17 P Bq of caesium-137 which is 7 times higher than the fallout from the Chernobyl accident. The modelled radioactive contamination is linked with data on transfer to the food chain and statistics on production and hunting to assess the consequences for foodstuffs. The investigation has been limited to the terrestrial environment, focussing on wild berries, fungi, and animals grazing unimproved pastures (i.e. various types of game, reindeer, sheep and goats). The predicted consequences are severe - especially in connection to sheep and goat production. Up to 80 % of the lambs in Norway could be exceeding the food intervention levels for radiocaesium the first years after the fallout, with 30-40 % likely to be above for many years. There will, consequently, be a need for extensive countermeasures in large areas for years or even decades involving several hundred thousand animals each year. Large consequences are also expected for reindeer husbandry - the first year in particular due to the time of fallout which is just prior to winter slaughter. The consequences will be most sever for reindeer herding in middle and southern parts of Norway, but problems may reach as far north as Finnmark where we find the majority of Norwegian reindeer production. The consequences for game will mostly depend on the regional

The objectives of the research were: (1) to examine the concentrations of metals in Vimba melanops and Rana temporaria and (2) to evaluate the potential risks of the contaminated organisms to human health in Makedonska Kamenica region. Analyses identified high levels of Cr, Hg, Ni and Pb in studied animals, which also exceeded their permissible levels in food. In sediment and soil samples, levels of Cd, Cu, Cr, Pb, Zn and As were perceived, while Cd, Cu, Ni, Pb, Se and As were increased in water samples. Results of transfer factor revealed that the examined animals had higher bioaccumulation rate from surrounding waters than from sediments or soils. The accomplished Health Risk Index disclosed that studied animals can have considerably high health risks for inhabitants. Conclusively, they could be considered as highly contaminated with metals and can consequently harm human health, especially children in their early development stages. -- Highlights: •The study merges the accumulation of PTE in animal species, sediments, soils and water. •Correlation between different media and their impact to living organisms'. •Considerably high health risks for inhabitants. -- In the Makedonska Kamenica region had been described several potential sources of exposure therefore exists the potential threat to human health

High throughput-screening of animal urine samples: It is fast but is it also reliable?

Kaufmann, Anton

2016-05-01

Advanced analytical technologies like ultra-high-performance liquid chromatography coupled to high resolution mass spectrometry can be used for veterinary drug screening of animal urine. The technique is sufficiently robust and reliable to detect veterinary drugs in urine samples of animals where the maximum residue limit of these compounds in organs like muscle, kidney, or liver has been exceeded. The limitations and possibilities of the technique are discussed. The most critical point is the variability of the drug concentration ratio between the tissue and urine. Ways to manage the false positive and false negatives are discussed. The capability to confirm findings and the possibility of semi-targeted analysis are also addressed.

CAUSES AND CONSEQUENCES OF THE SCHOOL IN HIGH SCHOOL DROPOUT: CASE UNIVERSIDAD AUTÓNOMA DE SINALOA

Directory of Open Access Journals (Sweden)

Rosalva Ruiz-Ramírez

2014-07-01

Full Text Available The present investigation has the objective to establish the personal, economic and social causes and consequences that create school desertion of high school in Universidad Autónoma de Sinaloa (UAS. The investigation took place in the high school located in the municipality of El Fuerte, Sinaloa, in the academic unit (UA of San Blas and its extensions The Constancia and The Higueras of the Natoches in 2013. A mixed approach was used to analyze qualitative and quantitative information; the studied population was 18 women and 17 men deserters of the school cycle 2011-2012, ten teachers, four directors and twenty non-deserting students. In the results one can see that the principal factor for school desertion was the personnel to be married and not approving classes. The main consequence was economic, highlighting that the poverty cycle is hard to break.

Obesity results from prolonged imbalance of energy intake and energy expenditure. Animal models have provided a fundamental contribution to the historical development of understanding the basic parameters that regulate the components of our energy balance. Five different types of animal model have been employed in the study of the physiological and genetic basis of obesity. The first models reflect single gene mutations that have arisen spontaneously in rodent colonies and have subsequently been characterized. The second approach is to speed up the random mutation rate artificially by treating rodents with mutagens or exposing them to radiation. The third type of models are mice and rats where a specific gene has been disrupted or over-expressed as a deliberate act. Such genetically-engineered disruptions may be generated through the entire body for the entire life (global transgenic manipulations) or restricted in both time and to certain tissue or cell types. In all these genetically-engineered scenarios, there are two types of situation that lead to insights: where a specific gene hypothesized to play a role in the regulation of energy balance is targeted, and where a gene is disrupted for a different purpose, but the consequence is an unexpected obese or lean phenotype. A fourth group of animal models concern experiments where selective breeding has been utilized to derive strains of rodents that differ in their degree of fatness. Finally, studies have been made of other species including non-human primates and dogs. In addition to studies of the physiological and genetic basis of obesity, studies of animal models have also informed us about the environmental aspects of the condition. Studies in this context include exploring the responses of animals to high fat or high fat/high sugar (Cafeteria) diets, investigations of the effects of dietary restriction on body mass and fat loss, and studies of the impact of candidate pharmaceuticals on components of energy

Nutritional ecology of obesity: from humans to companion animals.

Raubenheimer, David; Machovsky-Capuska, Gabriel E; Gosby, Alison K; Simpson, Stephen

2015-01-01

We apply nutritional geometry, a framework for modelling the interactive effects of nutrients on animals, to help understand the role of modern environments in the obesity pandemic. Evidence suggests that humans regulate the intake of protein energy (PE) more strongly than non-protein energy (nPE), and consequently will over- and under-ingest nPE on diets with low or high PE, respectively. This pattern of macronutrient regulation has led to the protein leverage hypothesis, which proposes that the rise in obesity has been caused partly by a shift towards diets with reduced PE:nPE ratios relative to the set point for protein regulation. We discuss potential causes of this mismatch, including environmentally induced reductions in the protein density of the human diet and factors that might increase the regulatory set point for protein and hence exacerbate protein leverage. Economics--the high price of protein compared with fats and carbohydrates--is one factor that might contribute to the reduction of dietary protein concentrations. The possibility that rising atmospheric CO₂ levels could also play a role through reducing the PE:nPE ratios in plants and animals in the human food chain is discussed. Factors that reduce protein efficiency, for example by increasing the use of ingested amino acids in energy metabolism (hepatic gluconeogenesis), are highlighted as potential drivers of increased set points for protein regulation. We recommend that a similar approach is taken to understand the rise of obesity in other species, and identify some key gaps in the understanding of nutrient regulation in companion animals.

Gains from trans-boundary water quality management in linked catchment and coastal socio-ecological systems: a case study for the Minho region

Worldwide, aquatic and coastal ecosystems are affected by point and diffuse source water pollution originating from rural, urban and industrial land uses in catchments, even though these ecosystems are of vital importance from an environmental and economic perspective. Integrated Catchment and Coastal Zone Management (ICCZM) specifically takes into account this inherent relationship between terrestrial land use, surface and ground water pollution, aquatic and coastal ecosystem state, and associated environmental values. To warrant sustainable regional economic development, we need to balance the marginal costs from terrestrial water pollution abatement and the associated marginal benefits from aquatic and coastal resource appreciation. In doing so, however, we need to differentiate between intra- and trans-boundary catchments because benefactors and beneficiaries from water quality improvement are not one and the same. In trans-boundary catchments, private (national) welfare maximizing rates of water quality improvement differ across nations as benefits from water quality improvement generally accrue to one nation while the costs are paid by multiple nations. While approaches for water quality management in linked catchment and coastal socio-ecological systems are fairly recent though existent, water quality management in trans-boundary catchments poses additional challenges. The objective of this paper is to develop and apply a deterministic optimal control approach that allows us to explore private and social welfare maximizing rates of water pollution abatement in linked catchment and coastal socio-ecological systems. For a case study of the Minho region in the Iberian Peninsula, we estimate nation-specific water pollution abatement cost (based on management practice adoption) and benefit (based on aquatic and coastal environmental values) functions, to determine as well as compare private (national) and social (trans-national) welfare maximizing rates of water

In vitro meat: A future animal-free harvest.

Science.gov (United States)

Bhat, Zuhaib Fayaz; Kumar, Sunil; Bhat, Hina Fayaz

2017-03-04

In vitro meat production is a novel idea of producing meat without involving animals with the help of tissue engineering techniques. This biofabrication of complex living products by using various bioengineering techniques is a potential solution to reduce the ill effects of current meat production systems and can dramatically transform traditional animal-based agriculture by inventing "animal-free" meat and meat products. Nutrition-related diseases, food-borne illnesses, resource use and pollution, and use of farm animals are some serious consequences associated with conventional meat production methods. This new way of animal-free meat production may offer health and environmental advantages by reducing environmental pollution and resource use associated with current meat production systems and will also ensure sustainable production of designer, chemically safe, and disease-free meat as the conditions in an in vitro meat production system are controllable and manipulatable. Theoretically, this system is believed to be efficient enough to supply the global demand for meat; however, establishment of a sustainable in vitro meat production would face considerably greater technical challenges and a great deal of research is still needed to establish this animal-free meat culturing system on an industrial scale.

Gaps in US Animal Welfare Law for Laboratory Animals: Perspectives From an Animal Law Attorney.

Science.gov (United States)

Frasch, Pamela D

2016-05-01

The use of animals in biomedical, toxicological, and basic research has been common practice, and a tool for scientists and researchers, for many years. And yet, serious conflict continues to exist between those who believe that the use of animals in research will yield scientific results that benefit humans and those who believe such practices are unethical regardless of use or outcome. High-profile undercover cases have further raised public awareness and have put the entire industry under pressure to be transparent, accountable, and aggressive in its adoption of reduction, refinement, and replacement (3R) principles. Many animal law attorneys are deeply frustrated by what they see as weak US laws that are unevenly enforced, especially when compared with legal advances in other countries and regions. This article (1) explores those gaps in US animal welfare laws with an emphasis on the Animal Welfare Act, (2) argues in favor of stronger laws and rigorous enforcement, and (3) suggests steps to advance these goals. These steps include (1) expanding the definition of "animal" in the Animal Welfare Act (AWA), (2) improving and expanding minimum care requirements in USDA regulations, (3) instituting mandatory reporting requirements, improving Institutional Animal Care and Use Committees, and allowing easier accessibility to laboratory reports and plans, (4) adding a citizen suit provision to the AWA, and (5) continuing education about the emotional and social capacities of animals and a stronger commitment to 3R principles. © The Author 2017.

The importance of leptin in animal science

Directory of Open Access Journals (Sweden)

Mirela Ahmadi

2016-05-01

Full Text Available There are two different neurons that control the energetic homeostasis in animals: appetite-stimulating and appetite-suppressing neurons. Leptin is a peptide hormone (also known as “satiety hormone”, released by adipose cells, being an anorexigenic compound which inhibit the hunger. Leptin function in animal organism is opposite by the action of ghrelin – a peptide hormone acting as an orexigenic compound that activate the hunger sensation. The quantity of leptin produced in organism is correlated by the size and the number of adipocytes, and of course by the lipid tissue mass. The action of leptin is in accordance with the neuropeptide Y that signaling the brain to increase the appetite and make the animal to eat. When the animals lose weight, the mass of adipose tissue is diminished, that has as consequence a decrease the leptin concentration in the blood. Blood leptin is correlated also with other characteristics, such as: fasting for a short term, stress, physical activity, sleep duration (prehibernation and hibernation, insulin concentration, obesity and diabetes.

The effects of a high-animal- and a high-vegetable-protein diet on mineral balance and bowel function of young men.

Science.gov (United States)

Van Dokkum, W; Wesstra, A; Luyken, R; Hermus, R J

1986-09-01

1. Twelve young men were given for periods of 20 d, each of three mixed diets, namely a low-protein (LP) diet (9% total energy as protein, 67% of animal origin), a high-animal-protein (HA) diet (16% total energy as protein, 67% of animal origin) and a high-vegetable-protein (HV) diet (16% total energy as protein, 67% of vegetable origin). Retention of calcium, magnesium, iron, zinc and copper as well as various bowel function indices were investigated during each dietary period. 2. Neither the HA diet nor the HV diet changed the retention of the minerals considerably. Only Fe balance decreased significantly on the HV diet. 3. Substituting the HV diet for the HA diet resulted in significant increases in faecal wet weight (17 g/d), defaecation frequency (0.12 stools/d), faecal volatile fatty acids (2.6 mmol/d) and a decrease in faecal bile acids (128 mumol/d). 4. It is concluded that a HV diet, rather than a HA diet is to be recommended with respect to bowel function, whereas the HV diet does not necessarily have a significant influence on mineral retention.

Consequences of long-term power outages and high electricity prices lasting for months

International Nuclear Information System (INIS)

2005-01-01

Several areas in the world have experienced electricity outages for longer periods of time, but the consequences of these are sparsely documented. There is a need for further analysis of the socioeconomic consequences of the outages. In addition to KILE (Quality adjusted revenue framework for un supplied energy) costs one has to take into account that the costs often increase proportionally with the durance of the outage, and that KILE tariffs do not reflect lost consumer's surplus for products that are not produced during an outage. A good example is the public underground transport, where the company's economical loss can be significantly smaller than the loss of utility value for the travellers. If the authorities act with reasonability it is difficult to see that periods with very high prices represent a big problem. The most important problems are related to diffused effects, especially for households with a weak economy. These problems can be solved with improved contractual forms (price guarantees) or by transfers to the households, without weakening the incentives for electricity economising (ml)

[Animal testing ethics and human testing. Thoughts on our conduct with and our relationship to animals].

Science.gov (United States)

Locker, Alfred

2004-01-01

After many years of experimental work with animals of diverse species, the author felt confronted with the question whether the great expenditure of sacrificed animal life would pay off when compared with the results gained. By self-critically considering his work, he gradually experienced a conversion from an unconcerned experimenter to a man feeling a deep sympathy with his fellow creatures. This motivated him to ponder the true nature of animals. Instead of applying ethics--though justified in its own realm--the author preferred to look at the problem using the General Systems Theory (GST), which can describe "the other side" of any system, the side into which any system may occasionally or necessarily transform. It occurred to him to assume that--provided we see a living organism as a system (as Ludwig von Bertalanffy, the founder of GST, did)--the "other side" of the animal would correspond to an innocent "genius" who suffers for man (thereby assuming a Christ-like position), whereas in its transitory life the true essence of the animal is hidden. Thus, by fancifully viewing the role of animals destined to suffer, a connection between GST and theology or religion arises. The consequence for us would be to pay honour to the test animal, irrespective of whether or not painful experiments could be avoided. The differentiation between a sacrifice (spiritually surrendering for a greater good) and a victim (involuntarily subjected to suffering) reveals that the experimental animal primarily belongs to the latter. But it can be elevated to the former when the full meaning of its suffering becomes obvious. The same holds true for "human testing", if, in contrast to the formidable atrocities, e.g. of concentration camps, the momentum of voluntariness is guaranteed, as pioneers of medical research frequently demonstrated by carrying out experiments on themselves.

Black swans?statistically improbable events with profound consequences?happen more often than expected in financial, social, and natural systems. Our work demonstrates the rare but systematic presence of black-swan events in animal populations around the world (mostly birds, mammals, and insects).

Black-swan events are not driven by life history (e.g., lifespan) but by ex...

A stationary excitation focus produced in the sensorimotor cortex of a rabbit by rhythmic electrodermal paw stimulation was manifested in the reaction to a testing sound stimulus earlier indifferent for the animal. Regardless of the stimulated paw (left or right), reactions to the testing stimuli appeared approximately in the equal percent of cases (70.7% and 71.5%, respectively). After a single-trial induction of the "animal hypnosis" state, it was difficult to produce the dominant focus by simulation of the left paw, whereas the results of the right-paw stimulation did not differ from those obtained during control stimulation. Consequently, the influence of hypnosis on defensive stationary excitation foci in different hemispheres was not the same.

We studied the tolerance of living organisms, such as a small animal (Milnesium tardigradum), a small crustacean (Artemia), non-vascular plants or moss (Ptichomitrium and Venturiella), and a vascular plant (Trifolium) to the extremely high hydrostatic pressure of 7.5 GPa. It turned out that most of the high pressure exposed seeds of white clover were alive. Those exposed to 7.5 GPa for up to 1 day and seeded on agar germinated roots. Those exposed for up to 1 hour and seeded on soil germinated stems and leaves. Considering the fact that proteins begins to unfold around 0.3 GPa, it seems difficult to understand that all the living samples which have been investigated can survive after exposure to 7.5 GPa.

Theoretical considerations on maximum running speeds for large and small animals.

Science.gov (United States)

Fuentes, Mauricio A

2016-02-07

Mechanical equations for fast running speeds are presented and analyzed. One of the equations and its associated model predict that animals tend to experience larger mechanical stresses in their limbs (muscles, tendons and bones) as a result of larger stride lengths, suggesting a structural restriction entailing the existence of an absolute maximum possible stride length. The consequence for big animals is that an increasingly larger body mass implies decreasing maximal speeds, given that the stride frequency generally decreases for increasingly larger animals. Another restriction, acting on small animals, is discussed only in preliminary terms, but it seems safe to assume from previous studies that for a given range of body masses of small animals, those which are bigger are faster. The difference between speed scaling trends for large and small animals implies the existence of a range of intermediate body masses corresponding to the fastest animals.

The Transboundary Aquifer Management Challenge: Linking Landscape Patterns and Groundwater Nitrate Concentrations in the Abbotsford-Sumas Aquifer, USA/Canada

Science.gov (United States)

Gallagher, T.; Gergel, S. E.

2015-12-01

Changes in land use and landscape pattern can have an array of impacts on aquatic systems, including impacts which span international waters and borders. Globally, agricultural land use patterns and practices are among the factors responsible for elevated nitrate concentrations in groundwater aquifers. Coordination of landscape monitoring across trans-boundary aquifers is needed to monitor and address contamination issues as landscape patterns can vary widely among different political jurisdictions. Landscape indicators, which quantify the amount and arrangement of land cover (such as proportion and abundance of land cover types), are one such way to improve our understanding of cross-border aquatic system interactions. In Western North America, the Abbotsford-Sumas Aquifer (ASA) spans the US-Canada border and provides drinking water for over 100,000 people. Intensive agriculture combined with high precipitation and well-drained soils make this aquifer susceptible to nitrate leaching. To understand how landscape patterns influence nitrate concentrations, we ask: Which landscape indicators correlate most strongly with elevated nitrate concentrations? A seamless cross-border land cover mosaic was created by harmonizing a variety of US and Canadian geodata. Auxiliary high spatial resolution imagery (e.g., 5m RapidEye and historical Google Earth) were used to quantify fine-scale landscape features (such as number of farm field renovations) with suspected mechanistic links to nitrate sources. We examined groundwater nitrate concentrations in shallow wells (screens Environment Canada. Surrounding each well, terrestrial zones of influence (aligned with the directional flow of groundwater) were delineated within which landscape patterns were characterized. Multiple regression was used to compare the strength of relationships between land use practices and nitrate concentrations. Preliminary results show strong positive correlations between area of raspberry renovations and

The provisions contained in the Legislative Decree no.26 signed by Italy's President on 4th March 2014 will have a considerable impact on the future of experiments with animals. The article briefly describes the stages of the decree's complicated passage through Parliament and the resulting text, which includes bans on: the use of animals for xenotransplants or research on drugs of abuse; the breeding of dogs, cats and non-human primates for experimental use; research without anaesthetic or analgesics that causes pain to the animal, except when anaesthetics or analgesics are being investigated. There is widespread feeling in the scientific community that these provisions will hinder the advancement of biomedical research in Italy.

In veterinary vaccinology, the oral route of administration is an attractive alternative compared to the commonly used parenteral route. Yeasts have a number of properties that make them potential live delivery systems for oral vaccination purposes such as their high expression levels, their GRAS status, adjuvant properties, and post-translational modification possibilities. Consequently, yeasts have been employed for the expression of heterologous genes and for the production of therapeutic proteins. Yeast-based vaccines are reviewed with regard to their ability to express and produce antigens from pathogens for veterinary use. Many of these vaccines have been shown to elicit protective immune responses following oral immunization in animals. Ultimately, yeast-based oral vaccines may offer a potential opportunity for the development of novel ideal vaccines in veterinary medicine. Copyright © 2013 Elsevier Ltd. All rights reserved.

Phenomenological consequences of supersymmetry

International Nuclear Information System (INIS)

Hinchliffe, I.; Littenberg, L.

1982-01-01

This report deals with the phenomenological consequences of supersymmetric theories, and with the implications of such theories for future high energy machines. It is concerned only with high energy predictions of supersymmetry; low energy consequences (for example in the K/sub o/anti K/sub o/ system) are discussed in the context of future experiments by another group, and will be mentioned briefly only in the context of constraining existing models. However a brief section is included on the implication for proton decay, although detailed experimental questions are not discussed. The report is organized as follows. Section I consists of a brief review of supersymmetry and the salient features of existing supersymmetric models; this section can be ignored by those familiar with such models since it contains nothing new. Section 2 deals with the consequences for nucleon decay of SUSY. The remaining sections then discuss the physics possibilities of various machines; e anti e in Section 3, ep in Section 4, pp (or anti pp) colliders in Section 5 and fixed target hadron machines in Section 6

Environmental Contamination Genetic Consequences Monitoring on the Former Semipalatinsk Test Site: General Approach

International Nuclear Information System (INIS)

Seisebaev, A.T.; Bakhtin, M.M.; Zhapbasov, R.Zh.

1998-01-01

For an objective assessment of nuclear test consequences for the environment it is necessary, together with the investigation of radiation situation, to study live biological systems, particularly the genetic effects of chronic ionizing radiation. The long staying of plants and animals on the territories with the elevated radiation background level can lead to the change of organism genetic system. In this connection the monitoring of chronically exposed natural populations is of particular interest and can serve as the objective indicator of the scale of natural biota genetic damage. Basing on the results obtained during plant and animal studies one can indirectly assess the hazard of people genetic damage. Besides, studying the mutational process on natural populations exposed to the chronic ionizing radiation one can reveal new regularities, which are impossible to be detected in the laboratory conditions, and new aspects of radiation genetics. The issue of radiation adaptation of organisms affected by the various doses of ionizing radiation is very acute. The prerequisite of organism adaptation to the certain radiation background is genetic heterogeneity of individuals comprising the population and selection of radiation-induced individuals, which are the carriers of the mutation of high radioresistance. The uniqueness of the Semipalatinsk Test site and the necessity of long-term investigations of the nuclear test consequences for the environment demand the elaboration of principles for organization and utilization of natural population genetic monitoring. Radiation-genetic monitoring is the long-term observation of palpitation gene pool conditions, assessment and forecast of their spatial and time alteration, determination of limits of changes admitted under the condition of environmental radioactive contamination. It includes a series of the main research directions and has quite certain methodological peculiarities. In this paper we discuss the tasks of

Effects of climate change and population growth on the transboundary Santa Cruz aquifer

2012-01-01

The USA and Mexico have initiated comprehensive assessment of 4 of the 18 aquifers underlying their 3000 km border. Binational management of groundwater is not currently proposed. University and agency researchers plus USA and Mexican federal, state, and local agency staff have collaboratively identified key challenges facing the Santa Cruz River Valley Aquifer located between the states of Arizona and Sonora. The aquifer is subject to recharge variability, which is compounded by climate change, and is experiencing growing urban demand for groundwater. In this paper, we briefly review past, current, and projected pressures on Santa Cruz groundwater. We undertake first-order approximation of the relative magnitude of climate change and human demand drivers on the Santa Cruz water balance. Global circulation model output for emissions scenarios A1B, B1, and A2 present mixed trends, with annual precipitation projected to vary by ±20% over the 21st century. Results of our analysis indicate that urban water use will experience greater percentage change than climate-induced recharge (which remains the largest single component of the water balance). In the Mexican portion of the Santa Cruz, up to half of future total water demand will need to be met from non-aquifer sources. In the absence of water importation and with agricultural water use and rights increasingly appropriated for urban demand, wastewater is increasingly seen as a resource to meet urban demand. We consider decision making on both sides of the border and conclude by identifying short- and longer-term opportunities for further binational collaboration on transboundary aquifer assessment.

Paradigm Shift in Transboundary Water Management Policy: Linking Water Environment Energy and Food (weef) to Catchment Hydropolitics - Needs, Scope and Benefits

Science.gov (United States)

RAI, S.; Wolf, A.; Sharma, N.; Tiwari, H.

2015-12-01

The incessant use of water due to rapid growth of population, enhanced agricultural and industrial activities, degraded environment and ecology will in the coming decades constrain the socioeconomic development of humans. To add on to the precarious situation, political boundaries rarely embrace hydrological boundaries of lakes, rivers, aquifers etc. Hydropolitics relate to the ability of geopolitical institutions to manage shared water resources in a politically sustainable manner, i.e., without tensions or conflict between political entities. Riparian hydropolitics caters to differing objectives, needs and requirements of states making it difficult to administer the catchment. The diverse riparian objectives can be merged to form a holistic catchment objective of sustainable water resources development and management. It can be proposed to make a paradigm shift in the present-day transboundary water policy from riparian hydropolitics (in which the focal point of water resources use is hinged on state's need) to catchment hydropolitics (in which the interest of the basin inhabitants are accorded primacy holistically over state interests) and specifically wherein the water, environment, energy and food (WEEF) demands of the catchment are a priority and not of the states in particular. The demands of the basin pertaining to water, food and energy have to be fulfilled, keeping the environment and ecology healthy in a cooperative political framework; the need for which is overwhelming. In the present scenario, the policy for water resources development of a basin is segmented into independent uncoordinated parts controlled by various riparians; whereas in catchment hydropolitics the whole basin should be considered as a unit. The riparians should compromise a part of national interest and work in collaboration on a joint objective which works on the principle of the whole as against the part. Catchment hydropolitics may find greater interest in the more than 250

Animal health aspects of adaptation to climate change: beating the heat and parasites in a warming Europe.

Science.gov (United States)

Skuce, P J; Morgan, E R; van Dijk, J; Mitchell, M

2013-06-01

Weather patterns in northern European regions have changed noticeably over the past several decades, featuring warmer, wetter weather with more extreme events. The climate is projected to continue on this trajectory for the foreseeable future, even under the most modest warming scenarios. Such changes will have a significant impact on livestock farming, both directly through effects on the animals themselves, and indirectly through changing exposure to pests and pathogens. Adaptation options aimed at taking advantage of new opportunities and/or minimising the risks of negative impacts will, in themselves, have implications for animal health and welfare. In this review, we consider the potential consequences of future intensification of animal production, challenges associated with indoor and outdoor rearing of animals and aspects of animal transportation as key examples. We investigate the direct and indirect effects of climate change on the epidemiology of important livestock pathogens, with a particular focus on parasitic infections, and the likely animal health consequences associated with selected adaptation options. Finally, we attempt to identify key gaps in our knowledge and suggest future research priorities.

Deposition, translocation and effects of transuranic particles inhaled by experimental animals

Inhalation exposure constitutes the most likely route of entrance for transuranics into the body. Cancer is the most likely consequence of exposure, but several thousand workers have been exposed during the last 30 yrs without, so far, evidence of exposure-related effects. Several soluble and insoluble transuranic compounds have been studied in rodents and dogs, either alone or combined with exposure to other materials (e.g., PuO/sub 2/--UO/sub 2/ fuel and Na). These studies have provided a wide variety of spatial and temporal dose distribution patterns in the lung. The distribution and total initial deposition in the respiratory tract is a function of the physical characteristics of the inhaled aerosols (size distribution, shape, hygroscopicity) and of the morphology and physiology of the animal. Translocation rates, organ and tissue distribution and excretion in urine and feces, are a function of the physicochemical characteristics of the deposited material (solubility, specific activity, chemical compound, etc.). Differences in rate of translocation of the solubilized material, primarily to the liver and bone, determines the radiation dose to the various tissues involved. Insoluble particles of plutonium dioxide are transferred to the thoracic lymph nodes, which may be functionally destroyed as a consequence. Radiation pneumonitis and pulmonary fibrosis are the main causes of death in animals with cumulative radiation doses to the lung of a few thousand rads. The most significant long-term effect of inhaled transuranic compounds in animals is the development of lung and bone tumors. The main type of lung tumor in both dog and rat is the bronchioloalveolar carcinoma (adenocarcinoma). However, tumor type is a function of radiation dose and dose-distribution at high doses. Bone ranks next to lung as the tissue developing the most tumors following inhalation of transuranics

Inhalation exposure constitutes the most likely route of entrance for transuranics into the body. Cancer is the most likely consequence of exposure, but several thousand workers have been exposed during the last 30 yrs without, so far, evidence of exposure-related effects.

The Idaho National Lab (INL) is leading a high-impact, national security-level initiative to reprioritize the way the nation looks at high-consequence risk within the industrial control systems (ICS) environment of the country’s most critical infrastructure and other national assets. The Consequence-driven Cyber-informed Engineering (CCE) effort provides both private and public organizations with the steps required to examine their own environments for high-impact events/risks; identify implementation of key devices and components that facilitate that risk; illuminate specific, plausible cyber attack paths to manipulate these devices; and develop concrete mitigations, protections, and tripwires to address the high-consequence risk. The ultimate goal of the CCE effort is to help organizations take the steps necessary to thwart cyber attacks from even top-tier, highly resourced adversaries that would result in a catastrophic physical effect. CCE participants are encouraged to work collaboratively with each other and with key U.S. Government (USG) contributors to establish a coalition, maximizing the positive effect of lessons-learned and further contributing to the protection of critical infrastructure and other national assets.

Ambient fine particulate matter (PM 2 .5) levels at the Metro Manila air sampling stations of the Philippine Nuclear Research Research Institute were found to be above the WHO guideline value of 10 μg m 3 indicating, in general, very poor air quality in the area. The elemental components of the fine particulate matter were obtained using the energy-dispersive x-ray fluorescence spectrometry. Positive matrix factorization, a receptor modelling tool, was used to identify and apportion air pollution sources. Location of probable transboundary air pollutants were evaluated using HYSPLIT (Hybrid Single Particle Lagrangian Integrated Trajectory Model) while location of probable local air pollutant sources were determined using the conditional probability function (CPF). Air pollutant sources can either be natural or anthropogenic. This study has shown natural air pollutant sources such as volcanic eruptions from Bulusan volcano in 2006 and from Anatahan volcano in 2005 to have impacted on the region. Fine soils was shown to have originated from China's Mu US Desert some time in 2004. Smoke in the fine fraction in 2006 show indications of coming from forest fires in Sumatra and Borneo. Fine particulate Pb in Valenzuela was shown to be coming from the surrounding area. Many more significant air pollution impacts can be evaluated with the identification of probable air pollutant sources with the use of elemental fingerprints and locating these sources with the use of HYSPLIT and CPF.

Are innate immune signaling pathways in plants and animals conserved?

Science.gov (United States)

Ausubel, Frederick M

2005-10-01

Although adaptive immunity is unique to vertebrates, the innate immune response seems to have ancient origins. Common features of innate immunity in vertebrates, invertebrate animals and plants include defined receptors for microbe-associated molecules, conserved mitogen-associated protein kinase signaling cascades and the production of antimicrobial peptides. It is commonly reported that these similarities in innate immunity represent a process of divergent evolution from an ancient unicellular eukaryote that pre-dated the divergence of the plant and animal kingdoms. However, at present, data suggest that the seemingly analogous regulatory modules used in plant and animal innate immunity are a consequence of convergent evolution and reflect inherent constraints on how an innate immune system can be constructed.

The etiology of metabolic syndrome (MetS) is complex and involves the interplay between environmental, lifestyle and genetic determinants. MetS in men can be associated with a biochemical pattern of partial hypogonadotropic hypogonadism (HH). A similar pattern has been noted in both men and women with a variety of acute illnesses and chronic diseases, and there is ongoing debate regarding whether this phenomenon might adaptive (e.g. diverting resources from reproduction into survival), or maladaptive (e.g. anemia, sarcopenia, osteopenia and fatigue of androgen-deficiency amplify and widen the adverse consequences of the original disease-trigger). In women with hypothalamic amenorrhea (HA-HH secondary to chronic bioenergetic deficit from dietary restriction and/or intensive exercise), a genetic link to congenital HH (CHH) was recently established; women carrying monoallelic CHH gene mutations will typically not develop CHH, but are significantly more susceptible to HA. However, the male reproductive axis seems to be more resistant to similar environmental insults. In contrast, MetS-associated HH (mHH) is specifically a male phenomenon; the reproductive phenotype of females with MetS tending instead towards hyperandrogenism, rather than hypogonadism. The underlying pathogenic mechanisms responsible for mHH have not been clearly identified and, as yet, there has been no investigation of a potential role for CHH mutation carriage in its etiology. Over the decades, the use of either genetic- or diet-induced obesity and/or MetS animal models has greatly helped to illuminate the complex etiology of metabolic dysregulation, but the strong relationship between obesity/MetS and mHH in males has been largely neglected, with little or no information about the regulation of reproductive function by metabolic factors under conditions of bioenergetic excess. However, the pathogenic link between MetS and HH in males has been recently investigated in an animal model of high fat

A Critical Look at Biomedical Journals’ Policies on Animal Research by Use of a Novel Tool: The EXEMPLAR Scale

Directory of Open Access Journals (Sweden)

Ana Raquel Martins

2015-04-01

Full Text Available Animal research is not only regulated by legislation but also by self-regulatory mechanisms within the scientific community, which include biomedical journals’ policies on animal use. For editorial policies to meaningfully impact attitudes and practice, they must not only be put into effect by editors and reviewers, but also be set to high standards. We present a novel tool to classify journals’ policies on animal use—the EXEMPLAR scale—as well as an analysis by this scale of 170 journals publishing studies on animal models of three human diseases: Amyotrophic Lateral Sclerosis, Type-1 Diabetes and Tuberculosis. Results show a much greater focus of editorial policies on regulatory compliance than on other domains, suggesting a transfer of journals’ responsibilities to scientists, institutions and regulators. Scores were not found to vary with journals’ impact factor, country of origin or antiquity, but were, however, significantly higher for open access journals, which may be a result of their greater exposure and consequent higher public scrutiny.

Original Mycobacterial Sin, a consequence of highly homologous antigens?

Science.gov (United States)

Jenkins, A O; Michel, A; Rutten, V

The role of antigens shared between Mycobacteria in in-vivo cross-reactive immune responses in host animals, have been reported to be responsible for reduced BCG vaccination efficacy as well reduced specificity of routine immunological diagnostic tests. This presents with significant disease control challenges in humans and animals. The present review highlights the results of previous studies on the effect of pre-sensitization to environmental mycobacteria on either pathogenic mycobacteria and/or M. bovis BCG, in experimental animals. It also takes an in-depth view into assessing the genetic similarities and relationships between atypical mycobacteria and Mycobacterium tuberculosis complex (MTBC) and how they might explain the immunological imprint of environmental mycobacteria in directing the hosts' immune response upon subsequent exposure to other classes of mycobacteria. The outcome of this review suggests that genetic closeness between particular atypical mycobacteria and MTBC usually indicate a higher level of homology for certain shared protective antigens. This ultimately results in a higher level of cross reactive immune responses as compared with other atypical mycobacteria that are further away genetically. This would explain the different effects of environmental mycobacteria on MTBC that have been reported in the different studies. In other words the direction of the host immune system in response to exposure to MTBC would depend on the type of environmental mycobacteria that was encountered in the initial exposure. We also explain these mycobacterial interactions in the context of the phenomenon of "Original Mycobacterial Sin". The effects of these inevitable mycobacterial interactions on field diagnosis and control by vaccination and how to circumvent them are discussed. Copyright © 2017 The Authors.

Animal welfare: an animal science approach.

Science.gov (United States)

Koknaroglu, H; Akunal, T

2013-12-01

Increasing world population and demand for animal-derived protein puts pressure on animal production to meet this demand. For this purpose animal breeding efforts were conducted to obtain the maximum yield that the genetic makeup of the animals permits. Under the influence of economics which is the driving force behind animal production, animal farming became more concentrated and controlled which resulted in rearing animals under confinement. Since more attention was given on economics and yield per animal, animal welfare and behavior were neglected. Animal welfare which can be defined as providing environmental conditions in which animals can display all their natural behaviors in nature started gaining importance in recent years. This does not necessarily mean that animals provided with good management practices would have better welfare conditions as some animals may be distressed even though they are in good environmental conditions. Consumers are willing to pay more for welfare-friendly products (e.g.: free range vs caged egg) and this will change the animal production practices in the future. Thus animal scientists will have to adapt themselves for the changing animal welfare rules and regulations that differ for farm animal species and countries. In this review paper, animal welfare is discussed from an animal science standpoint. Crown Copyright © 2013. Published by Elsevier Ltd. All rights reserved.

Millions of people die every year from diseases caused by exposure to outdoor air pollution1, 2, 3, 4, 5. Some studies have estimated premature mortality related to local sources of air pollution6, 7, but local air quality can also be affected by atmospheric transport of pollution from distant sources8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18. International trade is contributing to the globalization of emission and pollution as a result of the production of goods (and their associated emissions) in one region for consumption in another region14, 19, 20, 21, 22. The effects of international trade on air pollutant emissions23, air quality14 and health24 have been investigated regionally, but a combined, global assessment of the health impacts related to international trade and the transport of atmospheric air pollution is lacking. Here we combine four global models to estimate premature mortality caused by fine particulate matter (PM2.5) pollution as a result of atmospheric transport and the production and consumption of goods and services in different world regions. We find that, of the 3.45 million premature deaths related to PM2.5 pollution in 2007 worldwide, about 12 per cent (411,100 deaths) were related to air pollutants emitted in a region of the world other than that in which the death occurred, and about 22 per cent (762,400 deaths) were associated with goods and services produced in one region for consumption in another. For example, PM2.5 pollution produced in China in 2007 is linked to more than 64,800 premature deaths in regions other than China, including more than 3,100 premature deaths in western Europe and the USA; on the other hand, consumption in western Europe and the USA is linked to more than 108,600 premature deaths in China. Our results reveal that the transboundary health impacts of PM2.5 pollution associated with international trade are greater than those associated with long-distance atmospheric pollutant transport.

Social carry-over effects on non-social behavioral variation: mechanisms and consequences

Directory of Open Access Journals (Sweden)

Petri Toivo Niemelä

2015-05-01

Full Text Available The field of animal personality is interested in decomposing behaviors into different levels of variation, with its present focus on the ecological and evolutionary causes and consequences of expressed variation. Recently the role of the social environment, i.e. social partners, has been suggested to affect behavioral variation and induce selection on animal personality. Social partner effects exist because characters of social partners (e.g. size, behavior, affect the behavioral expression of a focal individual. Here, we 1 first review the proximate mechanisms underlying the social partner effects on behavioral expression and the timescales at which such effects might take place. We then 2 discuss how within- and among-individual variation in single behaviors and covariation between multiple behaviors, caused by social partners, can carry-over to non-social behaviors expressed outside the social context. Finally, we 3 highlight evolutionary consequences of social carry-over effects to non-social behaviors and 4 suggest study designs and statistical approaches which can be applied to study the nature and evolutionary consequences of social carry-over effects on non-social behaviors. Understanding the proximate mechanisms underpinning the social partner effects is important since it opens a door for deeper understanding of how social environments can affect behavioral variation and covariation at multiple levels, and the evolution of non-social behaviors (i.e. exploration, activity, boldness that are affected by social interactions.

This paper analyses the design and impact of capacity building programmes aimed at enhancing capacities of riparian professionals to address and resolve transboundary issues in international river basins. The case study is a programme developed by the Mekong River Commission (MRC). A post-training evaluation was applied to assess its impact in terms of individual capacity enhancement and change (use and application of knowledge, factors hampering application, and change in function and opportunities within the organisation). The design of the Capacity Building Programme of the MRC Flood Management and Mitigation Programme required a well balanced range of subjects (such as IWRM (integrated water resources management), model and decision support systems, and international water law). The post-training evaluation, 6 months after the last training workshop, showed an increase in familiarity with the topics for all 37 respondents, with the highest increase for the respondents with few years of working experience and from training and education institutions. The relevance of the subjects taught was highlighted by 95% of the respondents, and 78% of the participants had already used some of the acquired knowledge in their job. The respondents indicated that they did not have sufficient opportunities to apply all knowledge. The phased implementation and training of lecturers during the training workshops had a good impact, directly through increasing involvement in facilitation and delivery of the capacity building programme and through the use of the knowledge gained in short courses and development of curricula at their institute. For these types of capacity building programmes, a few recommendations can be made. The selection of participants is crucial for the application of the learned knowledge in their work. The integrative nature of transboundary water issues calls for a capacity building programme addressing a wide range of subjects, which can be understood by a

Animal welfare and the human-animal bond: considerations for veterinary faculty, students, and practitioners.

Science.gov (United States)

Wensley, Sean P

2008-01-01

Consideration of the human-animal bond typically focuses on the benefits of companion animals to human health and well-being, but it is essential that in realizing these benefits the welfare needs of the animals, both physical and mental, are also met. Positive emotional relationships with animals are likely to increase recognition of animal sentience and so help create positive attitudes toward animals at the societal level, but, at the individual level, the animals to which humans are bonded should also benefit from the human-animal relationship. A strong human-animal bond may benefit animal welfare (e.g., by motivating an owner to commit time and funds to necessary veterinary medical treatment), but may also be the source of compromised welfare. Highly bonded owners may, for example, be reluctant to permit euthanasia on humane grounds, and the anthropomorphic nature of many human-companion animal bonds can contribute to the development of problem behaviors and obesity. The challenge for the veterinary profession is to ensure that widespread positive sentiment toward animals, which the human-animal bond generates, is translated in to human behavior and actions that are conducive to good animal welfare. This, it is suggested, can be achieved through adequate veterinary education in veterinary and animal welfare science, ethics, and communication.
