    Saving of toner/ink consumption is an important task in modern printing devices. It has a positive ecological and social impact. We propose technique for converting print-job pictures to a recognizable and pleasant color sketches. Drawing a "pencil sketch" from a photo relates to a special area in image processing and computer graphics - non-photorealistic rendering. We describe a new approach for automatic sketch generation which allows to create well-recognizable sketches and to preserve partly colors of the initial picture. Our sketches contain significantly less color dots then initial images and this helps to save toner/ink. Our bio-inspired approach is based on sophisticated edge detection technique for a mask creation and multiplication of source image with increased contrast by this mask. To construct the mask we use DoG edge detection, which is a result of blending of initial image with its blurred copy through the alpha-channel, which is created from Saliency Map according to Pre-attentive Human Vision model. Measurement of percentage of saved toner and user study proves effectiveness of proposed technique for toner saving in eco-friendly printing mode.

    Explanations are given on the recent movements in the bio-technology applications. In the United States, gene therapy has been applied to patients having damaged immune system, while in Japan the first outdoor experiment is about to begin this year on gene recombined tomatoes. In the area of the marine bio-technology, researches carried out by the industrial, governmental, and academic sectors combined, led by the Ministry of International Trade and Industry have begun, which include such an attractive subject as finding out new kinds of algae living on carbon dioxide as their special favorite diet to use them to prevent the earth warming-up. On the other hand, the difficulty of bio-business is represented by the fact that venture business groups are absorbed into larger chemical companies. In Japan, the bio-business established in individual regions related to soy bean paste and Shoyu sauce industry is a distinct feature. Deregulations and review on the patent system are in progress in the United States and Germany aiming at strengthening the business competitiveness. Expectation is placed on the bio-technology that it will contribute largely in the future to solving such a critical environmental problem as experienced in the Persian Gulf war. 1 tab.

    This paper introduces the American International Group (AIG) which makes conceptions and risks of bio-remediation its business, as to how the Group is really working on the business. Features of the continuing remediation involving corporations managed by AIG include the following: It has economical superiority; in-situ purification of contaminated soils is possible; and it can solve contamination issues in a short time, and makes reuse of lands possible. The remediation uses a principle of promoting the contamination purifying actions of the natural world. It activates microorganisms by supplying oxygen, water, and nutrients in suitable amounts for microbial activities to decompose chemical wastes and converts them into harmless substances such as CO2. Objects of purification include petroleum-based substances, herbicides, insecticides, and solvents. Establishing optimal parameters before purification (mediator variables and population parameters) and protocols is important. The system goes through the following steps: Hydraulic and geological experts identify patterns and levels of contamination; microorganism experts find optimal parameters in laboratories; engineers design treatment systems; and site technicians operate the system. 6 refs., 3 figs.

    The combating of oil spill at sea surface by chemical dispersants accelerates the evaporation and disperse the oil into the water column, where it is broken down by natural processes and/or is sedimented at the sea bottom, especially at near coastal shallow areas, ports and marinas. The usual methodology for cleaning the sedimented oil from the sea bottom is mainly carried out via excavation and dumping of the polluted sediment into deeper sea areas, where the contamination is transferred from one area to another. The eco-friendly bio-solvent MSL Aqua 250 is an innovative new solution based mainly on natural constituents. The action mechanism and the effectiveness of this eco-friendly solvent is based on the high surface tension process. Organic compounds, including hydrocarbons upon coming in contact with MSL Aqua 250 solvent generate a significant surface tension reaction, which is able to alter the organic compounds to liquid form and then to drastically evaporate it. The use of MSL Aqua 250 solvent, both at sea surface and at the bottom, has the following advantages compared to the dispersants: • Efficient solution without transferring the pollution from sea surface to the water column and to the bottom or disturbing the Aquatic Eco System. • Non-Toxic. • Environmentally friendly with a restoration of marine life in the Eco System. • Cost effective. The MSL Aqua 250 solvent has been tested in cooperation with the Cyprus Department of Fisheries and Marine Research and the Technological University of Cyprus and used during the years 2015 and 2016 in marinas and fishing shelters in Cyprus faced oil pollution, with high concentration in the sea water and at the sea bottom of chemical parameters (BOD5, COD, FOG, TKN, TP, TPH), with excellent results.

    The world has witnessed growing complexities in disease scenario influenced by the drastic changes in host-pathogen- environment triadic relation. Pharmaceutical R&Ds are in constant search of novel therapeutic entities to hasten transition of drug molecules from lab bench to patient bedside. Extensive animal studies and human pharmacokinetics are still the "gold standard" in investigational new drug research and bio-equivalency studies. Apart from cost, time and ethical issues on animal experimentation, burning questions arise relating to ecological disturbances, environmental hazards and biodiversity issues. Grave concerns arises when the adverse outcomes of continued studies on one particular disease on environment gives rise to several other pathogenic agents finally complicating the total scenario. Thus Pharma R&Ds face a challenge to develop bio-waiver protocols. Lead optimization, drug candidate selection with favorable pharmacokinetics and pharmacodynamics, toxicity assessment are vital steps in drug development. Simulation tools like Gastro Plus™, PK Sim®, SimCyp find applications for the purpose. Advanced technologies like organ-on-a chip or human-on-a chip where a 3D representation of human organs and systems can mimic the related processes and activities, thereby linking them to major features of human biology can be successfully incorporated in the drug development tool box. PBPK provides the State of Art to serve as an optional of animal experimentation. PBPK models can successfully bypass bio-equivalency studies, predict bioavailability, drug interactions and on hyphenation with in vitro-in vivo correlation can be extrapolated to humans thus serving as bio-waiver. PBPK can serve as an eco-friendly bio-waiver predictive tool in drug development. Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.

    Dengue is considered one of the most important vector-borne diseases in Thailand. Its incidence is increasing despite routine implementation of national dengue control programmes. This study, conducted during 2010, aimed to demonstrate an application of integrated, community-based, eco-bio-social strategies in combination with locally-produced eco-friendly vector control tools in the dengue control programme, emphasizing urban and peri-urban settings in eastern Thailand. Three different community settings were selected and were randomly assigned to intervention and control clusters. Key community leaders and relevant governmental authorities were approached to participate in this intervention programme. Ecohealth volunteers were identified and trained in each study community. They were selected among active community health volunteers and were trained by public health experts to conduct vector control activities in their own communities using environmental management in combination with eco-friendly vector control tools. These trained ecohealth volunteers carried out outreach health education and vector control during household visits. Management of public spaces and public properties, especially solid waste management, was efficiently carried out by local municipalities. Significant reduction in the pupae per person index in the intervention clusters when compared to the control ones was used as a proxy to determine the impact of this programme. Our community-based dengue vector control programme demonstrated a significant reduction in the pupae per person index during entomological surveys which were conducted at two-month intervals from May 2010 for the total of six months in the intervention and control clusters. The programme also raised awareness in applying eco-friendly vector control approaches and increased intersectoral and household participation in dengue control activities.

    A survey was conducted of bio-chemical complex harmonized with the global environment for the purpose of constructing the material production process harmonized with the environment by the process fusion between biological conversion and chemical reaction. Palm oil was taken up as renewable raw material plant resource. The process utilizing bio-chemical reaction advances at normal temperature and pressure and is high in reaction specificity and selectivity. This is a recycling, circulation and environmental harmony type production technology which brings high yield, energy conservation, resource conservation, and low environmental loads. Waste water treatment and production of useful substances from sludge were thought as elementary technology. A possibility was studied of enzyme production by culturing solid waste, and the enzyme was applied to the hydrolysis process. The paper indicated trace components in the palm oil and the extraction method and proposed the production process of new derivatives for adding value to hydrolysate. A study was also made of the overall process flow which integrated these new processes and the material balance. The comprehensive evaluation of this new process was made from the aspect of the product structure, the market, construction cost, economical efficiency, and the environment. 133 refs., 65 figs., 56 tabs.

    Novel synthesis strategy of eco-friendly bio-nanocomposite films have been exploited using cellulose nanocrystals (CNC) and polyvinyl alcohol/carboxymethyl cellulose (PVA/CMC) blend matrix as a potential in food packaging application. The CNC were extracted from sugarcane bagasse using sulfuric acid hydrolysis, and they were successfully characterized regarding their morphology, size, crystallinity and thermal stability. Thereafter, PVA/CMC-CNC bio-nanocomposite films, at various CNC contents (0.5-10wt%), were fabricated by the solvent casting method, and their properties were investigated. It was found that the addition of 5wt% CNC within a PVA/CMC increased the tensile modulus and strength by 141% and 83% respectively, and the water vapor permeability was reduced by 87%. Additionally, the bio-nanocomposites maintained the same transparency level of the PVA/CMC blend film (transmittance of ∼90% in the visible region), suggesting that the CNC were dispersed at the nanoscale. In these bio-nanocomposites, the adhesion properties and the large number of functional groups that are present in the CNC's surface and the macromolecular chains of the PVA/CMC blend are exploited to improve the interfacial interactions between the CNC and the blend. Consequently, these eco-friendly structured bio-nanocomposites with superior properties are expected to be useful in food packaging applications. Copyright © 2016. Published by Elsevier B.V.

    Industrialization of bio-energy relies on the supply of resources on a large scale. The theoretical biomass resources could reach 2.61-3.51 billion tce (tons of coal equivalent)/a in China, while the available feedstock is about 440-640 million tce/a, however, among this only 1.5-2.5% has been transferred into energy at present. Marginal land utilization has great prospects of supplying bio-energy resources in China, with co-benefits, such as carbon sequestration, water/soil conservation, and wind erosion protection. There is a large area of marginal land in China, especially in northern China, including about 263 million ha of desertification land, 173 million ha of sand-land, and 17 million ha of salinizatin land. The plant species suitable to be grown in marginal lands, including some species in Salix, Hippophae, Tamarix, Caragana, and Prunus is also abundant Biomass feedstock in marginal lands would be 100 million tce/a in 2020, and 200 million tce/a in 2050. As a result, a win-win situation of eco-society and bio-energy development could be realized, with an expected 4-5% reduction of total CO{sub 2} emission in China in 2020-2050. Although much progress has been made in the field of bio-energy research in China, yet significant efforts should be taken in the future to fulfill large-scale industrialization of bio-energy.

    We report the synthesis of Y2O3: Eu(3+) (1-11 mol%) nanoparticles (NPs) with different morphologies via eco-friendly, inexpensive and simple low temperature solution combustion method using Aloe Vera gel as fuel. The formation of different morphologies of Y2O3: Eu(3+) NPs were characterized by PXRD, SEM, TEM, HRTEM, UV-Visible and PL techniques. The PXRD data and Rietveld analysis confirms the formation of single phase Y2O3 with cubic crystal structure. The influence of Eu(3+) ion concentration on the morphology, UV-Visible absorption, PL emission and photocatalytic activity of Y2O3: Eu(3+) nanostructures were investigated. Y2O3: Eu(3+) NPs exhibit intense red emission with CIE chromaticity coordinates (0.50, 0.47) and correlated color temperature values at different excitation ranges from 1868 to 2600 K. The control of Eu(3+) ion on Y2O3 matrix influences the photocatalytic decolorization of methylene blue (MB) as a model compound was evaluated under UVA light. Enhanced photocatalytic activity of conical shaped Y2O3: Eu(3+) (1 mol%) was attributed to dopant concentration, crystallite size, textural properties and capability of reducing the electron-hole pair recombination. The trend of inhibitory effect in the presence of different radical scavengers followed the order SO4(2-)>Cl(-)>C2H5OH>HCO3(-)>CO3(2-). These findings show great promise of Y2O3: Eu(3+) NPs as a red phosphor in warm white LEDs as well as eco-friendly heterogeneous photocatalysis. Copyright © 2015 Elsevier B.V. All rights reserved.

  20. Eco-epidemiological and pathological features of wildlife mortality events related to cyanobacterial bio-intoxication in the Kruger National Park, South Africa

    Full Text Available Over the past decade, several clustered, multispecies, wildlife mortality events occurred in the vicinity of two man-made earthen dams in the southern and south central regions of the Kruger National Park, South Africa. On field investigation, heavy cyanobacterial blooms were visible in these impoundments and analysis of water samples showed the dominance of Microcystis spp. (probably Microcystis aeruginosa. Macroscopic lesions seen at necropsy and histopathological lesions were compatible with a diagnosis of cyanobacterial intoxication. Laboratory toxicity tests and assays also confirmed the presence of significant levels of microcystins in water from the two dams. These outbreaks occurred during the dry autumn and early winter seasons when water levels in these dams were dropping, and a common feature was that all the affected dams were supporting a large number of hippopotamuses (Hippopotamus amphibius. It is hypothesised that hippopotamus’ urine and faeces, together with agitation of the sediments, significantly contributed to internal loading of phosphates and nitrogen – leading to eutrophication of the water in these impoundments and subsequent cyanobacterial blooms. A major cause for concern was that a number of white rhinoceros (Ceratotherium simum were amongst the victims of these bio-intoxication events. This publication discusses the eco-epidemiology and pathology of these clustered mortalities, as well as the management options considered and eventually used to address the problem.

    To build up and analyse the feasibility, process, and effectiveness of a partnership-driven ecosystem management intervention in reducing dengue vector breeding and constructing sustainable partnerships among multiple stakeholders. A community-based intervention study was conducted from May 2009 to January 2010 in Yangon city. Six high-risk and six low-risk clusters were randomized and allocated as intervention and routine service areas, respectively. For each cluster, 100 households were covered. Bi-monthly entomological evaluations (i.e. larval and pupal surveys) and household acceptability surveys at the end of 6-month intervention period were conducted, supplemented by qualitative evaluations. Intervention description: The strategies included eco-friendly multi-stakeholder partner groups (Thingaha) and ward-based volunteers, informed decision-making of householders, followed by integrated vector management approach. Pupae per person index (PPI) decreased at the last evaluation by 5·7% (0·35-0·33) in high-risk clusters. But in low-risk clusters, PPI remarkably decreased by 63·6% (0·33-0·12). In routine service area, PPI also decreased due to availability of Temephos after Cyclone Nargis. As for total number of pupae in all containers, when compared to evaluation 1, there was a reduction of 18·6% in evaluation 2 and 44·1% in evaluation 3 in intervention area. However, in routine service area, more reduction was observed. All intervention tools were found as acceptable, being feasible to implement by multi-stakeholder partner groups. The efficacy of community-controlled partnership-driven interventions was found to be superior to the vertical approach in terms of sustainability and community empowerment.

    This project investigates the effectiveness and feasibility of scaling-up an eco-bio-social approach for implementing an integrated community-based approach for dengue prevention in comparison with existing insecticide-based and emerging biolarvicide-based programs in an endemic setting in Machala, Ecuador. An integrated intervention strategy (IIS) for dengue prevention (an elementary school-based dengue education program, and clean patio and safe container program) was implemented in 10 intervention clusters from November 2012 to November 2013 using a randomized controlled cluster trial design (20 clusters: 10 intervention, 10 control; 100 households per cluster with 1986 total households). Current existing dengue prevention programs served as the control treatment in comparison clusters. Pupa per person index (PPI) is used as the main outcome measure. Particular attention was paid to social mobilization and empowerment with IIS. Overall, IIS was successful in reducing PPI levels in intervention communities versus control clusters, with intervention clusters in the six paired clusters that followed the study design experiencing a greater reduction of PPI compared to controls (2.2 OR, 95% CI: 1.2 to 4.7). Analysis of individual cases demonstrates that consideration for contexualizing programs and strategies to local neighborhoods can be very effective in reducing PPI for dengue transmission risk reduction. In the rapidly evolving political climate for dengue control in Ecuador, integration of successful social mobilization and empowerment strategies with existing and emerging biolarvicide-based government dengue prevention and control programs is promising in reducing PPI and dengue transmission risk in southern coastal communities like Machala. However, more profound analysis of social determination of health is called for to assess sustainability prospects. © The author 2015.

    In this study, an eco-friendly soy protein adhesive was developed that utilized two components from soybean meal without addition of any toxic material. A plant-based, water-soluble and inexpensive soybean soluble polysaccharide was used as the novel renewable material to combine with soy protein to produce a soy protein adhesive. Three-plywood was fabricated with the resulting adhesive, and its wet shear strength was measured. The results showed the wet shear strength of plywood bonded by the adhesive reached 0.99MPa, meeting the water resistance requirement for interior use panels. This improvement was attributed to the following reasons: (1) Combination of cross-linked soybean soluble polysaccharide and soy protein formed an interpenetrating network structure, improving the thermal stability and water resistance of the cured adhesive. (2) Adding CL-SSPS decreased the adhesive viscosity to 15.14Pas, which increased the amount of the adhesive that penetrate the wood's surface and formed more interlocks.

    2016-01-01

    Tyrosinase (EC 1.14.18.1) a copper-containing monooxygenase, isolated from a fungal isolate Aspergillus niger PA2 was subjected for immobilization onto a composite consisting of chitosan and gelatin biopolymers. The homogeneity of the chitosan-gelatin biocomposite film was characterized by X-ray diffraction analyses. To evaluate immobilization efficiency, chitosan-gelatin-Tyr bio-composite films were analyzed by field emission scanning electron microscopy, atomic force microscopy and UV-spectroscopy. The rough morphology of the film led to a high loading of enzyme and it could retain its bioactivity for a longer period. The enzyme adsorbed onto the film exhibited 72% of its activity after 10 days and exhibited good repeatability for up to nine times, after intermittent storage. Moreover, the immobilized enzyme exhibited broader pH and temperature profile as compared to free counterpart. Immobilized enzyme was further evaluated for the synthesis of L-DOPA (2,4-dihydroxy phenylalanine) which is a precursor of dopamine and a potent drug for the treatment of Parkinson's disease and for myocardium neurogenic injury.

    2015-06-01

    Full Text Available La «crisis ambiental», a causa de la novedad, tiene dos características muy importantes. De un lado está el lenguaje en dos perspectivas. En la apreciación de Gastón Bachelard, el problema de la diversidad de conceptualizaciones y teorizaciones al respecto, y del lado de Nicholas Georgescu-Roegen, la carencia de una clara certificación. La “Ética de la Tierra”, escrita por Aldo Leopold fue una primera aproximación a la configuración de un comportamiento ético referido a la problemática ambiental; luego vino la concepción bioética, que por carencia de su certificación, no logró una fundamentación operacional ni teórica adecuada. En este sentido se hace necesario clarificar muy bien el lenguaje para tener una expresión definida sobre esa crisis ambiental, la cual se ubica dentro de una temática que desborda el interés científico y se constituye en una preocupación política a todos los niveles. La otra característica es ser una temática claramente transdisciplinaria, lo que hace necesario avanzar sobre una buena fundamentación operacional y teórica para evitar discusiones sin un objeto claro de trabajo que conduzca a referentes distintos e indistinguibles.

  9. Umberto Eco - autobiograf?

    Directory of Open Access Journals (Sweden)

    Regina Lubas-Bartoszyńska

    2009-01-01

    Full Text Available This text shows that U. Eco is an autobiographer in only some sense of the word. He has not written an autobiobiographical text in which he would present a segment of his life. However, he told the history of his novelistic work and presented his intellectual train of thought in his essays, interviews, introductions to his works. There also exists an indirect autobiographism in Eco, which expresses signs of the author's life and of his personality dispersed in his interpretative and theoretical writings on literature, aesthetics, history, in his feuilletons and in his novels. Five types of autobiographism have been distinguished in Eco as well as five autobiographical strategies within the indirect autobiographism. The first strategy - a strong presence of autorial I in the text - is not sufficient and requires support of some other of the strategies discussed.

    Full Text Available Techniques that analyze biological remains from sediment sequences for environmental reconstructions are well established and widely used. Yet, identifying, counting, and recording biological evidence such as pollen grains remain a highly skilled, demanding, and time-consuming task. Standard procedure requires the classification and recording of between 300 and 500 pollen grains from each representative sample. Recording the data from a pollen count requires significant effort and focused resources from the palynologist. However, when an adaptation to the recording procedure is utilized, efficiency and time economy improve. We describe EcoCount, which represents a development in environmental data recording procedure. EcoCount is a voice activated fully customizable digital count sheet that allows the investigator to continuously interact with a field of view during the data recording. Continuous viewing allows the palynologist the opportunity to remain engaged with the essential task, identification, for longer, making pollen counting more efficient and economical. EcoCount is a versatile software package that can be used to record a variety of environmental evidence and can be installed onto different computer platforms, making the adoption by users and laboratories simple and inexpensive. The user-friendly format of EcoCount allows any novice to be competent and functional in a very short time.

    uncontrolled or premature differentiation and the onset of senescence [12]. Stressing the importance of in vitro environments, even regulatory agencies like the US-FDA use in vitro manipulation as a gauge to classify cell therapies[13]. In this issue, a diverse assortment of articles ranging from the use of scaffolds for in vitro culture by Gomathysankar et al [14] to employing tools for in vivo transplantation of cells by Maiti et al [15]and Fauzi et al [16] have been published. During regenerative medicine applications, cells undergo several transitions across environments, starting with an in vivo to in vitro transition when harvested from the body and subjected to culture-expansion or tissue engineering kind of processing and then a reversal back to an in vivo environment. While the factors and materials employed in the in vitro eco-system are known, their effects are known though to an extent, some of their implications still remain unknown and the mechanisms of those implications are largely obscure [17-19]. These bunch of changes in the whole eco-system inside-out and vice versa need a meticulous and flawless assessment which is indispensable in improvising the clinical outcome of regenerative medicine applications.

  13. The Eco House

    Energy Technology Data Exchange (ETDEWEB)

    Hobbett, A. (Leicester Ecology Trust (United Kingdom))

    The Eco House is a former park keeper's lodge on the periphery of Leicester's largest public park. Taken over by Leicester Ecology Trust in 1990, the Eco House was a successor to the Trust's earlier low energy house. This has been a local authority decant house, retrofitted to show the potential for increased energy efficiency in older buildings. Many of the ideas from the earlier project were adopted by the new with a widening of its remit to include all matters of environmental concern connected with people's homes. So in addition to energy efficiency, other issues addressed include conservation of resources, wildlife, organic gardening, food production, water, environmental consumerism, recycling and health. Given that the use of energy is regarded by many environmentalists to be the single most important environmental issue today, and one which is easiest for households to address, it remains the project's dominant theme.

    Krebs, J.R.; Davies, N.B.

    1981-01-01

    Eco-ethology is the science of the effects of animal behaviour on animal environment and the effects of animal environment on animal behaviour, with the purpose to find out how natural selection within this control loop has formed and molded animals. N. Tinbergen was the first to make experiments on the evolution of patterns of behaviour which are influenced not only by the evolution of species but also by their adaptation to a changing environment. R.H. MacArthur then introduced mathematical modelling for better clarification of the function and adoptive value of behavioural patterns. The book gives a detailed description of both methods and a successful attempt at a synthesis. In surveys and specific contribution, an exemplary outline of eco-ethology is presented, with information, ideas and reflections that are of interest both to teachers and students. The book is addressed to biologists, zoologists, ecologists, sociologists, and evolutionary biologists and to students of these disciplines. (orig.) [de

    Full Text Available Environmental marketing (Eco-marketing, as a relatively new movement, emerged at the beginning of the 20th century, is in the growing phase of its development. Eco-labeling and other ways/types of eco-marketing are attracting more attention of consumers, since they are aware of the necessity of nature conservation and environmental protection. There has been a lot of misunderstanding and miss leadings in interpretation and substantiation of ecomarketing claims in previous period of time. One of the most concrete improvements in eco-marketing was appearance and establishment of ISO 14020 guidelines. ISO 14020 guidelines are integral part of ISO 14000 series of standards, which could be implemented in eco-marketing. At the same time, development of "green" products and marketing of "green" products, are direct positive contributions to resources reduction, environmental protection and sustainable economic development. Companies designing this kind of products can expect better position on the market, improvement of competitiveness, reduction of expenses (less raw materials, less waste, less harmful effects on the environment, raising corporate social responsibility, higher export.

    2003-12-01

    Life without chemicals would be inconceivable, but the potential risks and impacts to the environment associated with chemical production and chemical products are viewed critically. Eco-efficiency analysis considers the economic and life cycle environmental effects of a product or process, giving these equal weighting. The major elements of the environmental assessment include primary energy use, raw materials utilization, emissions to all media, toxicity, safety risk, and land use. The relevance of each environmental category and also for the economic versus the environmental impacts is evaluated using national emissions and economic data. The eco-efficiency analysis method of BASF is briefly presented, and results from three applications to chemical processes and products are summarized. Through these applications, the eco-efficiency analyses mostly confirm the 12 Principles listed in Anastas and Zimmerman (Environ. Sci. Technol. 2003, 37(5), 94A), with the exception that, in one application, production systems based on bio-based feedstocks were not the most eco-efficient as compared to those based on fossil resources. Over 180 eco-efficiency analyses have been conducted at BASF, and their results have been used to support strategic decision-making, marketing, research and development, and communication with external parties. Eco-efficiency analysis, as one important strategy and success factor in sustainable development, will continue to be a very strong operational tool at BASF.

    Kahoush, M.; Behary, N.; Cayla, A.; Nierstrasz, V.

    2017-10-01

    In recent years, immobilization of oxidoreductase enzymes on electrically conductive materials has played an important role in the development of sustainable bio-technologies. Immobilization process allows the re-use of these bio-catalysts in their final applications. In this study, different methods of immobilizing redox enzymes on conductive textile materials were used to produce bio-functionalized electrodes. These electrodes can be used for bio-processes and bio-sensing in eco-designed applications in domains such as medicine and pollution control. However, the main challenge facing the stability and durability of these electrodes is the maintenance of the enzymatic activity after the immobilization. Hence, preventing the enzyme’s denaturation and leaching is a critical factor for the success of the immobilization processes.

    2004-01-01

    suitable marine bio-films can give to stainless electrodes the same properties as platinum for oxygen reduction. This discovery might open the way to unexpected innovative processes based on the exploitation of the 'corrosive' properties of bio-films. The same trend has been initiated with the approach of marine anaerobic bio-corrosion of carbon steels. In this case, iron sulphur deposits are known to exert a preponderant role in corrosion. Nevertheless, innovative results have put in light an unexpected coupling between the presence of phosphate species and the enzyme hydrogenase. Such a possible coupling has already been suggested in previous studies, but it has never been clearly stated. Deciphering this process may lead to new track in understanding bio-corrosion of carbon steels on the one side, but also to a new eco-friendly process for hydrogenase-catalysed carbon steel phosphating. Both cases represent different illustrations of the capabilities of marine bio-corrosion to be the source of unexpected innovative biotechnological processes. (authors)

    Eco-innovation is an important way to realize sustainable development. It has the dual positive externality of "knowledge spillover" and "environmental spillover", which has attracted much attention from theory and practice. In order to systematically grasp the current situation of eco-innovation, this study collected the relevant foreign literatures on eco-innovation in the past ten years, and made a systematic review of the definition, characteristics and dimensions of eco-innovation. Focusing on the theory of institutional theory, stakeholder theory and resource-based view, this paper explored the antecedents of eco-innovation. Then, this paper also demonstrated the positive and negative effects of eco-innovation on corporate financial performance, and the meditating and moderating mechanisms between eco-innovation and financial performance. Finally, based on the limitations of existing research, the future research direction was put forward.

    2014-05-01

    Full Text Available Eco-design is a new domain, required by the new trends and existing concerns worldwide, generated by the necessity of adopting new design principles. New design principles require the designer to provide a friendly relationship between concept created, environment and consume. This "friendly" relationship should be valid both at present and in the future, generating new opportunities for product, product components or materials from which it was made. Awareness, by the designer, the importance of this new trend, permits the establishment of concepts that have as their objective the protection of present values and ensuring the legacy of future generations. Ecodesig, by its principles, is involved in the design process, from early stage, the stage of product design. Priority objective of the designers will consist in reducing the negative effects on the environment through the entire life cycle and after it is taken out of use. The main aspects of the eco-design will consider extending product exploitation, make better use of materials, reduction of emission of waste. The design process in the "eco"domein must be started by selecting the function of the concept, materials and technological processes, causing the shape of macro and micro geometric of the product through an analysis that involves optimizing and streamlining the product. This paper presents the design process of a cross-sports footwear concept, built on the basis of the principles of ecodesign

    This report constitutes the user's guide to the biosphere model ECOS and provides a detailed description of the processes modelled and mathematical formulations used. The FORTRAN code ECOS is an equilibrium-type compartmental biosphere code. ECOS was designed with the objective of producing a general but comprehensive code for use in the assessment of the radiological impact of unspecified geological repositories for radioactive waste. ECOS transforms the rate of release of activity from the geosphere to the rate of accumulation of weighted committed effective dose equivalent (dose). Both maximum individual dose (critical group dose) and collective dose rates may be computed. (author)

    The bio-nano interface is the boundary where engineered nanomaterials (ENMs) meet the biological system, exerting the biological function for which they have been designed or inducing adverse effects on other cells or organisms when they reach nontarget scenarios (i.e., the natural environment). Research has been performed to determine the fate, transport, and toxic properties of ENMs, but much of it is focused on pristine or so-called as-manufactured ENMs, or else modifications of the materials were not assessed. We review the most recent progress regarding the bio-nano interface and the transformations that ENMs undergo in the environment, paying special attention to the adsorption of environmental biomolecules on the surface of ENMs. Whereas the protein corona has received considerable attention in the fields of biomedics and human toxicology, its environmental analogue (the eco-corona) has been much less studied. A section dedicated to the analytical methods for studying and characterizing the eco-corona is also presented. We conclude by presenting and discussing the key problems and knowledge gaps that need to be resolved in the near future regarding the bio-nano interface and the eco-corona.

    2017-09-01

    Full Text Available Although many authors agree on the role of personal values in explaining the main determinants of eco-behaviour, disagreement about the effects of socio-demographic features exists, particularly about the effect of nationality. In an attempt to fill this gap in the literature, this paper contributes to the debate surrounding the main determinants of eco-behaviour, based on a cross-country analysis. To test the role of nationality and personal values in eco-behaviour, a linear regression model involving 353 Chinese and 333 Italian subjects was performed. A stepwise analysis was then conducted to identify the main significant effects. The explorative and stepwise analyses confirmed that nationality is significant when explaining individual eco-behaviour, for both Italian and Chinese people. Moreover, the linear regression model, as a stepwise analysis, showed that regulatory focus and universalism are the main personal values influencing ecological behaviour. Differences emerging from the analysis show significant differences in terms of eco-behaviour and eco-awareness, for the two countries involved in the analysis, that might lead companies to adopt different marketing strategies when promoting eco-products.

    An optimization problem of two eco-energetic systems is described. The first one is close to the actual eco-energetic system in Romania, while the second is a new one, based on nuclear energy as primary source and hydrogen energy as secondary source. The optimization problem solved is to find the optimal structure of the systems so that the objective functions adopted, namely unitary energy cost C and total pollution P, to be minimum at the same time. The problem can be modelated with a bimatrix cooperative mathematical game without side payments. We demonstrate the superiority of the new eco-energetic system. (author)

    2011-01-01

    This study was designed to manage insect pests of Bt cotton through the manipulation of different eco-friendly techniques. A perusal of data, based on the overall performance of different treatments reflected that lowest population of jassids (0.29) was observed in bio-control treated Bt cotton followed by bio-control treated conventional cotton (0.41). Mean per leaf population of thrips was found lowest in insecticide treated Bt cotton (0.97) which was statically at par with bi-control treated conventional cotton (0.95), biocontrol treated Bt cotton (1.09) and colour traps treated Bt cotton (1.50). In case of white flies, bio-control treated Bt cotton and bio-control treated conventional cotton again proved effective in maintaining the population at lower levels per leaf (0.33 and 0.35 respectively). No bollworms infestation was recorded in transgenic cotton whereas higher attack of the same was observed in the untreated conventional cotton block. The best results were achieved with the application of bio-control agents in combination with Bt cotton resulting in least infestation by insect pests and maximum seed yield of 3657 kg/ha. The population of Chrysoperla carnea was significantly higher in Bt and conventional cotton treated with bio-control agents as compared to the other treatments. The parasitism percentage of Trichogramma chilonis was observed significantly higher in bio-control treated conventional cotton. The studies manifested that combination of bio-control technology with Bt cotton effectively preserves the local beneficial insect fauna indicating its potential to be used as integrated management system against different insect pests of cotton.

    Full Text Available Eco-innovation is any form of innovation resulting in or aiming at significant and demonstrable progress towards the goal of sustainable development, through reducing impacts on the environment, enhancing resilience to environmental pressures, or achieving a more efficient and responsible use of natural resources. States and governments of the world, different institutions and organizations actively involved and aware in public policies, strategies and actions, reaffirm their commitments and reassess actions in order to achieve a truly sustainable development. In the common vision and the resolutions and other documents of the United Nations Conference on Sustainable Development, Rio+20, the words "environment", "innovation", "green economy" appear very often and almost always along the same context, to achieve the objectives of the sustainable development. The objectives of EU's Europe 2020 strategy for smart, sustainable and inclusive growth, are being implemented through a number of Flagship Initiatives addressing the main challenges, like “Innovation for a sustainable Future - The Eco-innovation Action Plan (EcoAP”. Eco-innovation Observatory developed the Eco-Innovation index, the first tool to assess and illustrate eco-innovation performance across the EU Member States. Like in all fields, in textiles and leather field, eco-innovation is present and there are a lot of tools available that measure environmental damage and help manufacturers and brands become more sustainable. Eco-innovation is not just a trendy concept but a reality and a necessity nowadays, a way to achieve a sustainable future for ourselves and future generations.

    We report the use of the Second Harmonic Generation response from a riboflavin doped chitosan film as a characterization method of the film morphology. This film is of particular interest in the development of new and bio-sourced material for eco-friendly UV lithography. The method allows us to determine how riboflavin is distributed as a function of film depth in the sample. This possibility is of importance in order to have a better understanding of the riboflavin influence in chitosan films during the lithography process. On the contrary, linear optical techniques provide no information beyond the mere confirmation of the riboflavin presence.

    Considering the unique relevance of Brazilian biodiversity, this research aims to investigate the main barriers to biodiversity-based R&D and eco-design development in a leading national company which has been commended for its innovation and sustainability. The methodology for this research was based on on-location visits, in-depth interviews, and consensus building among R&D, sustainability, and quality managers. A multi-criteria decision-making (MCDM) approach was adopted through interpretive structural modelling (ISM), a method that assists decision makers to transform complex models with unclear data into structural models. Some of the most influential barriers to biodiversity-based eco-design initiatives are "lack of legal incentive", "not enough demand from the market", and "not enough available knowledge/scientific data." The most relevant barrier was "no legal incentive" from government. Consequently, managers should concentrate their efforts in tackling those barriers that may affect other barriers known as 'key barriers'. Government should work decisively toward promoting a framework of legal incentives for bio-based eco-design; otherwise, metaphorically, "there is not carnival without the samba singer who pushes the rhythm". The results given here reveal the barriers for bio-based eco-design in a Brazilian leading company, and this is the first work combining ISM to barriers to biodiversity R&D and eco-design.

  8. Bio-fuel barometer

    International Nuclear Information System (INIS)

    2015-01-01

    After a year of doubt and decline the consumption of bio-fuel resumed a growth in 2014 in Europe: +6.1% compared to 2013, to reach 14 millions tep (Mtep) that is just below the 2012 peak. This increase was mainly due to bio-diesel. By taking into account the energy content and not the volume, the consumption of bio-diesel represented 79.7% of bio-fuel consumption in 2014, that of bio-ethanol only 19.1% and that of biogas 1%. The incorporating rate of bio-fuels in fuels used for transport were 4.6% in 2013 and 4.9% in 2014. The trend is good and the future of bio-fuel seems clearer as the European Union has set a not-so-bad limit of 7% for first generation bio-fuels in order to take into account the CASI effect. The CASI effect shows that an increase of the consumption of first generation bio-fuels (it means bio-fuels produced from food crops like rape, soy, cereals, sugar beet,...) implies in fact a global increase in greenhouse gas release that is due to a compensation phenomenon. More uncultivated lands (like forests, grasslands, bogs are turned into cultivated lands in order to compensate lands used for bio-fuel production. In most European countries the consumption of bio-diesel increased in 2014 while it was a bad year for the European industry of ethanol because ethanol prices dropped by 16 %. Oil companies are now among the most important producers of bio-diesel in Europe.

    Bio-oils were produced from bench-scale slow-pyrolysis of three different biomass samples (corn stalks, poplar and switchgrass). Experimental protocols were developed and applied in order to screen their chemical composition. Several hazardous compounds were detected in the bio-oil samples analysed, including phenols, furans and polycyclic aromatic hydrocarbons. A procedure was outlined and applied to the assessment of toxicological and carcinogenic hazards of the bio-oils. The following hazardous properties were considered: acute toxicity; ecotoxicity; chronic toxicity; carcinogenicity. Parameters related to these properties were quantified for each component identified in the bio-oils and overall values were estimated for the bio-oils. The hazard screening carried out for the three bio-oils considered suggested that: (i) hazards to human health could be associated with chronic exposures to the bio-oils; (ii) acute toxic effects on humans and eco-toxic effects on aquatic ecosystems could also be possible in the case of loss of containment; and (iii) bio-oils may present a marginal potential carcinogenicity. The approach outlined allows the collection of screening information on the potential hazards posed by the bio-oils. This can be particularly useful when limited time and analytical resources reduce the possibility to obtain detailed specific experimental data. Copyright © 2012 Elsevier B.V. All rights reserved.

    In order to structure a chemical reaction process that does not discharge a large amount of waste by-products or harmful chemical substances, or so-called environment friendly process, investigations and discussions were given based on the results derived in the previous fiscal year. A proposal was made to reduce environmental load on development of oxidized and dehydrogenated catalysts that can produce selectively ethylene, propylene and isobutylene in an oxidation process. In liquid phase oxidation, redox-based oxidation and solid catalyzation of automatic oxidation reaction were enumerated. In acid base catalyst reaction, development of ultra strong solid acid was described to structure no pollution discharging process. In the fine chemical and pharmaceutical fields, the optical active substance method and the position-selective aromatics displacement reaction were evaluated to reduce environmental load. A questionnaire survey performed on major chemical corporations inside and outside the country revealed the following processes as the ones that can cause hidden environmental problems: processes discharging large amount of wastes, processes treating dangerous materials, and processes consuming large amount of energy. Development of catalysts is important that can realize high yield, high selectivity and reactions under mild conditions as a future environment harmonizing chemical process. 117 refs., 23 figs., 22 tabs.

    As an application example of water-absorbing polymers with biodegradability, it was expected to be applied to soil improvement agents used in planting trees in deserts, besides physiological napkins, paper diapers and medical materials. In this paper, water-absorbing polymers with biodegradability such as natural polymers, petroleum-made polymers and polymers synthesized by radiation cross-linking and chemical cross-linking were introduced. Moreover, a kind of water-absorbing polymers developed by the authors, made from polyamino acid synthesized by microbes, was introduced. In the method developed by the authors, the cross-linking structure could be made by combining PGA carboxyl groups and various amino groups of diamine using carbimide with water solubility. As for this method, all of reactions could be conducted in water and catalytic replacement was not necessary, moreover, hydrogel with the water-absorbing rate of 200 to 1500 times could be produced. 44 refs., 3 figs., 1 tab.

    Full Text Available The study of universities and their role in enterprise development, support and education is very mature. However when Isenberg coined the term ‘entrepreneurial ecosystem’ and suggested that higher education was one of the key foundation blocks of a regional eco-system it threw open the concept of the university having a wider role in the overall business, economic and civic life of a region. What is this wider role, and how do the universities themselves view their place in this evolving entrepreneurial eco-system? How do they fit into Regional Alliances set up to build regional economic development? This paper introduces two pilot Alliances that have been recently formed using both the education institutes and the wider eco-system to drive Innovation and Graduate Employability (The SHIP and REAL Alliances.

    To integrate measurements of eco-efficiency with control loop configuration has become an important topic since all industrial processes/plants are requested to increase their eco-efficiency. The exergy eco-efficiency factor, a new measure of eco-efficiency for control loop configuration, has been developed recently. The exergy eco-efficiency factor is based on the thermodynamic concept of exergy, which can be used to analyze a process in terms of its efficiency. The combination of the relative gain array (RGA), NI, CN, dynamic RGA, and the exergy eco-efficiency factor will help guide the process designer to find the optimal control design with low operating cost/eco-efficiency.

  18. SUSTAINABLE ECONOMIC GROWTH AND ECO-EFFICIENCY

    Directory of Open Access Journals (Sweden)

    Mariana\tLUPAN

    2015-06-01

    Full Text Available The current economic and social contexts have brought forth the issues regarding growth and sustainability. The concept of growth has always been linked to an increase in consumption levels, and this inevitably led to pressures on the environment and on the resources that support human activity. Given these circumstances, the question whether we can avoid an environmental disaster while maintaining economic growth, has become more stringent. We chose to approach this aspect by examining the concept of eco-efficiency, a concept that embodies aspects of both economic efficiency and environmental efficiency. Eco-efficiency can be regarded as the effectiveness with which resources are used in order to create products and services that satisfy human needs. Based on this idea, the last decade has produced an increasing number of studies on eco-efficiency and how it can be measured and implemented in the production of goods and services, but also in the field regarding demand patterns. An analysis regarding the aspects of eco-efficiency at the macro level of the Romanian economy is in line with the current environmental concerns, thus I have chosen to cover these questions, as well as the evolution of the locale economy towards a more sustainable development. The outcome of the examined aspects shows that, in spite of an increase in eco-efficiency levels, energy and material consumption and emissions have increased. This raises the question if measuring economic and environmental efficiency by reporting to the GDP value is becoming obsolete and if there is a need to revaluate eco-efficiency indicators in order to measure the transition to a greener and more sustainable development from different points of view.

    2015-03-01

    Full Text Available The aim of this article is to carry out a theoretical and empirical analysis of the process of eco-label diffusion. Eco-labels allow consumers to identify products and services that have a reduced environmental impact during their life cycle. Thus, they are aimed at diminishing the information gap between sellers and buyers. The results of the estimation using the Bass model indicate that the diffusion of the EU eco-label has been most dynamic in countries such as Hungary, Poland, Denmark, Germany and France. In turn, the scope of diffusion (absolute saturation level reached the highest value for companies in France and Italy. In addition, the results of the study confirm the stimulating impact of the scope of eco-label diffusion on consumer awareness of environmental issues. This finding points to the need for environmental education among consumers, which could in turn encourage firms to undertake pro-environmental actions.

    Wang, W.

    2011-01-01

    The demand to preserve the environment and form a sustainable development is greatly increasing in the recent decades all over the world, and this environmental concern is also merged in electrical power industry, resulting in many eco-design approaches in Transmission and Distribution (T and D) industries. As a method of eco-design, Life Cycle Assessment (LCA) is a systematic tool that enables the assessment of the environmental impacts of a product or service throughout its entire life cycle, i.e. raw material production, manufacture, distribution, use and disposal including all intervening transportation steps necessary or caused by the product's existence. In T and D industries, LCA has been done for a lot of products individually, in order to see one product's environmental impacts and to seek for ways of improving its environmental performance. This eco-design for product approach is a rather well-developed trend, however, as only a single electrical product cannot provide the electrical power to users, electrical system consists of a huge number of components, in order to investigate system's environmental profile, the entire environmental profiles of different composing products has to be integrated systematically, that is to say, a system approach is needed. Under this philosophy, the study 'Eco-design of Power Transmission Systems' is conducted in this thesis, with the purpose of analysing the transmission systems' environmental impacts, locating the major environmental burden sources of transmission systems, selecting and/or developing methodologies of reducing its environmental impacts.

  17. The Study of Critical Eco-Linguistic in Green Discourse: Prospective Eco-Linguistic Analysis

    Directory of Open Access Journals (Sweden)

    Tommi Yuniawan

    2017-10-01

    Full Text Available Eco-linguistic studies are influenced by one of the other interdisciplinary sciences, namely critical discourse analysis. The combination of these two sciences is called critical eco-linguistic studies. Critical eco-linguistic examines the discourse about the environment and various forms of discourse and their ideology which concerns people and the environment. The environmental discourse with all its manifestations (oral text, written text is called green discourse. To that end, critical eco-linguistic dictates the linguistic aspects contained in the green discourse. Utilization of lingual units in green discourse will affect the sense and logic of people involved in the discourse, ie the writers and readers or the speakers and the speakers. What is recorded in their cognition, will affect their attitudes and actions to the environment. If green discourse is constructive, then their attitude and actions to the environment are constructive. Conversely, if green discourse is more destructive and exploitative, then their attitudes and actions towards the environment will also be affected towards destruction and exploitation. For this reason, critical eco-linguistic studies in green discourse deserve to be given space as a form of prospective eco-linguistic analysis.

  18. Establishment of an eco-compensation fund based on eco-services consumption.

    Science.gov (United States)

    Liu, Moucheng; Yang, Lun; Min, Qingwen

    2018-04-01

    Eco-compensation is a type of institutional arrangement that uses economic measures to adjust the relationships among stakeholders in order to conserve and/or sustainably use ecosystem services. The externality of the value of ecosystem services is one of the theoretical bases for eco-compensation. Different types of ecosystem services are consumed by people from different regions. Some are consumed by people living where the services originate, while some are carried by rivers, wind, vehicles or other natural or manmade means to other areas. Thus, the flow and consumption of ecosystem services should be seen as the basis for establishing eco-compensation funds. This paper uses satellite images of the Zhang-Cheng area near Beijing in 2013 to discuss how to establish an eco-compensation fund for stakeholders in this area. Firstly, six important types of ecosystem services in the Zhang-Cheng area were identified based on ecological function zoning, and the value of these ecosystem services was calculated based on ecological pricing methods. Secondly, the field intensity model from physics was used to analyze where Zhang-Cheng area ecosystem services flowed and calculate how much of these services were used by other areas. Thirdly, based on this analysis and calculation, the paper proposes the rates that different stakeholders should invest in the eco-compensation fund, based on their consumption of eco-services.

    This study measures productive inefficiency within the context of multi-environmental pollution (eco-efficiency) in the Chinese industrial sector. The weighted Russell directional distance model is applied to measure eco-efficiency using production technology. The objective is to clarify how external factors affect eco-efficiency. The major findings are that both foreign direct investment and investment for pollution abatement improve eco-efficiency as measured by air pollutant substances. A levy system for wastewater discharge improves eco-efficiency as measured by wastewater pollutant substances. However, an air pollutant levy does not significantly affect eco-efficiency as measured by air pollutants.

    Highlights: • Calcium carbonate from seashell is an attractive bio-filler in polymeric industry. • We examine composition and thermal properties of calcium carbonate from seashell. • Used with eco-friendly epoxy matrices provides a high renewable content material. • Addition of 30 wt.% of seashell bio-filler increase of over 50% in flexural modulus. • Calcium carbonate from seashell leads higher thermal stability materials. - Abstract: The seashells, a serious environmental hazard, are composed mainly by calcium carbonate, which can be used as filler in polymer matrix. The main objective of this work is the use of calcium carbonate from seashells as a bio-filler in combination with eco-friendly epoxy matrices thus leading to high renewable contents materials. Previously obtaining calcium carbonate, the seashells were washed and grinded. The powder obtained and the resin was characterized by DSC, TGA, X-ray diffraction (XRD), X-ray fluorescence spectroscopy (XRF), and rheology plate-plate. The results show that addition of 30 wt.% of seashell bio-filler increase mechanical properties as flexural modulus (over 50%) and hardness Shore D (over 6%) and thermal properties as an increase around 13% in glass transitions temperature. The results show that the addition of calcium carbonate from seashells is an effective method to increase mechanical properties of bio-composite and to reduce the residue of seashells from industrial production

    2002-03-01

    For contributing to the preservation of the global environment, studies were made to work out a new energy introduction vision fully exploiting the characteristic features of Oita Prefecture. Oita Prefecture's demand for energy in 1998 is estimated to be 408.6 times 10{sup 15} J, with coal-based energy covering 204,016 TJ, oil-based energy 160,192 TJ, electric power 37,721 TJ, and so forth. The consumption will result in the emission of 35.77 million tons of carbon dioxide. According to Oita Prefecture's prospect of its eco-energy adoption in 2010, there will be 319 MW from hydroelectric power, 155 MW from geothermal power, 52 MW from photovoltaic power, 46 MW from clean energy vehicles, 33 MW from refuse-fueled power, and so forth. To prepare plans for facilities to utilize eco-energy and for regional development in the future through the use of such facilities, introduction costs were predicted and effects were simulated for model businesses engaged in biomass power generation using livestock wastes, small-scale hydroelectric power generation, bio-diesel fuel production, wind power generation, and woody biomass power generation.

    Knight Thomas F

    2008-04-01

    Full Text Available Abstract Background The underlying goal of synthetic biology is to make the process of engineering biological systems easier. Recent work has focused on defining and developing standard biological parts. The technical standard that has gained the most traction in the synthetic biology community is the BioBrick standard for physical composition of genetic parts. Parts that conform to the BioBrick assembly standard are BioBrick standard biological parts. To date, over 2,000 BioBrick parts have been contributed to, and are available from, the Registry of Standard Biological Parts. Results Here we extended the same advantages of BioBrick standard biological parts to the plasmid-based vectors that are used to provide and propagate BioBrick parts. We developed a process for engineering BioBrick vectors from BioBrick parts. We designed a new set of BioBrick parts that encode many useful vector functions. We combined the new parts to make a BioBrick base vector that facilitates BioBrick vector construction. We demonstrated the utility of the process by constructing seven new BioBrick vectors. We also successfully used the resulting vectors to assemble and propagate other BioBrick standard biological parts. Conclusion We extended the principles of part reuse and standardization to BioBrick vectors. As a result, myriad new BioBrick vectors can be readily produced from all existing and newly designed BioBrick parts. We invite the synthetic biology community to (1 use the process to make and share new BioBrick vectors; (2 expand the current collection of BioBrick vector parts; and (3 characterize and improve the available collection of BioBrick vector parts.

    European Union bio-fuel use for transport reached 12 million tonnes of oil equivalent (mtoe) threshold during 2009. The slowdown in the growth of European consumption deepened again. Bio-fuel used in transport only grew by 18.7% between 2008 and 2009, as against 30.3% between 2007 and 2008 and 41.8% between 2006 and 2007. The bio-fuel incorporation rate in all fuels used by transport in the E.U. is unlikely to pass 4% in 2009. We can note that: -) the proportion of bio-fuel in the German fuels market has plummeted since 2007: from 7.3% in 2007 to 5.5% in 2009; -) France stays on course with an incorporation rate of 6.25% in 2009; -) In Spain the incorporation rate reached 3.4% in 2009 while it was 1.9% in 2008. The European bio-diesel industry has had another tough year. European production only rose by 16.6% in 2009 or by about 9 million tonnes which is well below the previous year-on-year growth rate recorded (35.7%). France is leading the production of bio-ethanol fuels in Europe with an output of 1250 million liters in 2009 while the total European production reached 3700 million litters and the world production 74000 million liters.

The process of cleaning of contaminated facades involves the removal and eradication of micro flora on the surface of insulation using chemical products, killing cells and eliminating all living mass, including organic ingredients. The removal of bio corrosion coating from ETICS structure by means of chemical and preservative substances (biocides is currently the only effective and most used technology. Uncontrolled leaching of the used biocides is unacceptable. Meantime, new technology for environmentally safe maintenance of ETICS is needed. Scientists have been working on replacement the biocides currently used in facades treatment with eco-friendly biocides that have no negative effects on the environment or human beings. While the eco- treatment will be available, safe dewatering of chemicals being leached from the surface of the facade could be provided by e.g. special drain systems adjusted to the building type, use and age. The paper gives an overview of the problem in context of Slovakia and examples of leaching systems designed for new and renovated buildings.

  16. Eco-Efficiency Indicators for Urban Transport

    Directory of Open Access Journals (Sweden)

    Patrick Moriarty

    2015-06-01

    Full Text Available This paper focuses on urban passenger transport eco-efficiency, which can be defined as the production of maximum benefits to society while minimising environmental impacts from urban transport’s inputs of energy and materials. Researchers have intensively studied transport’s varied environmental impacts, particularly through Life Cycle Assessment; this paper argues that primary transport energy per capita is presently the best measure of impact. Although transport’s societal benefits have generally been regarded as self-evident, access to out-of-home activities, not passenger-km, should be considered as the fundamental useful output of an urban transport system, since transport is a derived demand. We argue that access levels are roughly similar in all high-income OECD cities, so that these cities can be ranked on transport eco-efficiency simply on the basis of per capita primary transport energy.

    The use of fossil energy is one of the major environmental problems associated with tourism and travel. Consequently, the need to limit fossil energy use has been highlighted as a precondition for achieving sustainable tourism development. However, tourism is also one of the most important sectors of the world economy, and fears have thus been expressed by the tourist industry and its organisations that increasing energy prices (for example, as a result of eco-taxes) could substantially decrease the economic welfare of countries and destinations. In this article, the interplay of environmental damage and economic gains is thus analysed within the context of tourism. Carbon dioxide-equivalent emissions are assessed in relation to the revenues generated, allowing for conclusions about the eco-efficiency of tourism

    Eco-ethology is the science of the effects of animal behaviour on animal environment and the effects of animal environment on animal behaviour, with the purpose to find out how natural selection within this control loop has formed and molded animals. N. Tinbergen was the first to make experiments on the evolution of patterns of behaviour which are influenced not only by the evolution of species but also by their adaptation to a changing environment. R.H. MacArthur then introduced mathematical modelling for better clarification of the function and adoptive value of behavioural patterns. The book gives a detailed description of both methods and a successful attempt at a synthesis. In surveys and specific contribution, an exemplary outline of eco-ethology is presented, with information, ideas and reflections that are of interest both to teachers and students. The book is addressed to biologists, zoologists, ecologists, sociologists, and evolutionary biologists and to students of these disciplines.

    as long-term perfomance. Resilience is not explicitly taken into account within life cycle assessment (LCA). LCA determines the eco-efficiency of product systems, i.e. the ratio between the function provided by the product and its impact on the environment. The question is whether a product system which...... structure is improved or designed to be more resilient will not only be more inefficient, but also eco-inefficient, when studied by means of LCA. In this work a two steps approach is proposed to study resilience of product systems: 1) assessment of disturbance conditions and their inclusion within the scope......, because the redundant connections between elements of a system make it less efficient but also more flexible and adaptable and allow to perform a function even if some connections are interrupted or missing. Balancing between resilience and efficiency seems to be the key for sustainability intended...

    In order to solve public health problems posed by the epidemiology of risk factors centered on the individual and neglecting the causal processes linking the risk factors with the health outcomes, Mervyn Susser proposed a multilevel epidemiology called eco-epidemiology, addressing the interdependence of individuals and their connection with molecular, individual, societal, environmental levels of organization participating in the causal disease processes. The aim of this epidemiology is to integrate more than a level of organization in design, analysis and interpretation of health problems. After presenting the main criticisms of risk-factor epidemiology focused on the individual, we will try to show how eco-epidemiology and its development could help to understand the need for a broader and integrative epidemiology, in which studies designed to identify risk factors would be balanced by studies designed to answer other questions equally vital to public health. © 2016 médecine/sciences – Inserm.

    2016-08-01

    Nutrients (nitrogen and phosphorus) from agricultural non-point source (NPS) pollution have been increasingly recognized as a major contributor to the deterioration of water quality in recent years. The purpose of this article is to investigate the discrepancies in interception of nutrients in agricultural NPS pollution for eco-soil reactors using different filling schemes. Parallel eco-soil reactors of laboratory scale were created and filled with filter media, such as grit, zeolite, limestone, and gravel. Three filling schemes were adopted: increasing-sized filling (I-filling), decreasing-sized filling (D-filling), and blend-sized filling (B-filling). The systems were intermittent operations via simulated rainstorm runoff. The nutrient removal efficiency, biomass accumulation and vertical dissolved oxygen (DO) distribution were defined to assess the performance of eco-soil. The results showed that B-filling reactor presented an ideal DO for partial nitrification-denitrification across the eco-soil, and B-filling was the most stable in the change of bio-film accumulation trends with depth in the three fillings. Simultaneous and highest removals of NH4(+)-N (57.74-70.52%), total nitrogen (43.69-54.50%), and total phosphorus (42.50-55.00%) were obtained in the B-filling, demonstrating the efficiency of the blend filling schemes of eco-soil for oxygen transfer and biomass accumulation to cope with agricultural NPS pollution.

    Urban planning and transportation system solutions and decisions have a large-scale significance for eco efficiency, the consumption of energy and other natural resources, the production of greenhouse gas and other emissions, and the costs caused by communities.Planning solutions may impact on greenhouse gas emissions by 10 % at regional level, by 20 % at local community level and even by 200 % at local dwelling area level. Impact on emissions caused by transportation is even bigger: at least double compared to the impact on total emissions. Similarly large impacts can be seen concerning consumption of energy and other natural resources as well as costs.The most important factors in sustainable urban and transportation planning are at dwelling area level: location, structure, building density, house types, space heating systems, at community and regional level: area density, energy consumption and production systems, location of and distances between dwellings, working places and services, transportation systems, possibilities of walking and cycling, availability of public transport, and necessity for use of private cars. The presentation is based on the author's research and case studies from 1992 to 2006. The assessment method EcoBalance was developed to assess sustainability of communities and it has been applied at different planning levels: regional plans, local master plans and detailed plans. The EcoBalance model estimates the total consumption of energy and other natural resources, the production of emissions and wastes and the costs caused directly and indirectly by communities on a life-cycle basis

    Full Text Available Abstract. The present paper aims to assess nitrogen circulation in an eco-technical system for egg production. The experiments were conducted in modelled conditions in an anthropogenic ecosystem of the “mesocosm” type, in which the unit of the bio-consumers and three eco-technological chains modelling the unit of the bio-decomposers are modelled: manure storing for decontamination /a recommendation on good farming practices/, composting and anaerobic decomposition in an installation for biogas production. A new criterion was implemented for the assessment of the chemical heterogeneity in the biogenic nitrogen cycle in the modified trophic chain – retention coefficient /k/, which is defined as the ratio of nitrogen introduced into the system / nitrogen content in the feed: its quantity in the secondary biological production x 100. The chemical heterogeneity at the level of organisms /differences in the individual components of eggs/ and at the biocenotic level is established. The biogenic nitrogen cycle in the eco-technical chain for egg production is characterized by an uneven distribution in both products of the outflow. The largest amount of nitrogen is found in the egg whites (k = 0.45, while it decreases significantly in egg yolks (k = 0.17 and reaches k = 0.03 in the egg shell, a.k.a. heterogeneity on the level of organisms is established. The nitrogen compounds introduced through the feed ration are concentrated in manure (k = 25.33. Losses of nitrogen are established in two of the manure utilization technologies. The quantity of /k/ in the compost is 20.32, a.k.a. the loss of nitrogen compounds is 19.8%. The biggest losses are found in manure storage; according to the recommendations on good farming practices (k = 18.82 or the reduction of nitrogen is 25.7% compared with fresh manure. Due to redistribution of the chemical elements /a significant part of C, H and O are included in biogas/, there is nitrogen concentration in bio slime

The deal is reported to be worth about $50 million in revenues to Eco Logic, spread over the next few years. The agreement includes provisions for the Japanese companies to purchase, or manufacture under licence, a number of Eco Logic's gas phase chemical reduction processing units to serve the Japanese market. In exchange for exclusive rights to the Japanese market, Eco Logic will receive license fees and royalties of up to nine per cent for the use of its process. Eco Logic is currently building a demonstration unit under contract with the two Japanese companies. The Japanese PCB waste destruction market is estimated to be worth as much as $400 million.

    2009-04-01

    Full Text Available The principal photosynthetic pathways convert solar energy differently depending on the environmental conditions and the plant morphotype. Partitioning of energy storage within crops will vary according to environmental and seasonal conditions as well. Highest energy concentration is found in terpens like latex and, to a lesser extent, in lipids. Ideally, we want plant ingredients with high energy content easily amenable to ready-to-use bio-fuel. Generally, these crops are adapted to drier areas and tend to save on eco-volume space. Competition with food crops could be avoided by fetching energy from cheap agricultural by-products or waste products such as bagasse in the sugar cane. This would in fact mean that reducing power of agricultural residues should be extracted from the biomass through non-photosynthetic processes like animal ingestion or industrial bio-fermentation. Conversion and transformation efficiencies in the production chain are illustrated for some relevant crops in the light of the maximum power theorem.

    The importance of the mutual interactions between biosphere in hydrosphere has become increasingly apparent in both the ecological and hydrological sciences. In hydrology, while the role of plants in controlling soil water balance has been recognized from some time, more subtle controls have also been realized, such as the impact of soil organic matter on soil water dynamics and soil properties, the plant control on infiltration, erosion, and geomorphology. Ecosystem dynamics and land-use changes have also been recognized to impact water availability and quality. On the other hand, biologists and ecologists have increased their attention towards the dynamics of the terrestrial water balance and its impact on plants (photosynthesis, plant growth and reproduction) as well as microbial life (and thus decomposition and the entire cycling of nutrients and carbon fluxes). In this eco-hydrological context, we discuss: (i) the need to distinguish complex from complicated eco- hydrologic behaviors, which are both expected to be present in systems with many degrees of freedom, spatial heterogeneity, nonlinearities and feedbacks (and with biological components). (ii) The use of ideas and tools from complex systems science and non-equilibrium statistical mechanics to explore possible emerging behaviors and patterns. (iii) The importance of intermittency and of the entire spectrum of eco-hydrologic fluctuations conferred by the system nonlinearities, and their connection to a possible theory of biologically- meaningful hydroclimatic extremes. (iv) The need for further research of basic questions yet unanswered (e.g., role of organic matter/roots on soil water balance and soil properties; vegetation control on infiltration; competition for water by plants; role of plant control on uptake (e.g., hydraulic lift)). (v) Ways to merge observations, minimalist models and complex numerical simulations as well as to increase communication of hydrologists with physicists, statisticians

    The use of diamond for advanced applications has been the dream of mankind for centuries. Until recently this dream has been realized only in the use of diamond for gemstones and abrasive applications where tons of diamonds are used on an annual basis. Diamond is the material system of choice for many applications, but its use has historically been limited due to the small size, high cost, and inconsistent (and typically poor) quality of available diamond materials until recently. The recent development of high quality, single crystal diamond crystal growth via the Chemical Vapor Deposition (CVD) process has allowed physcists and increasingly scientists in the life science area to think beyond these limitations and envision how diamond may be used in advanced applications ranging from quantum computing, to power generation and molecular imaging, and eventually even diamond nano-bots. Because of diamond's unique properties as a bio-compatible material, better understanding of diamond's quantum effects and a convergence of mass production, semiconductor-like fabrication process, diamond now promises a unique and powerful key to the realization of the bio-electronic devices being envisioned for the new era of medical science. The combination of robust in-the-body diamond based sensors, coupled with smart bio-functionalized diamond devices may lead to diamond being the platform of choice for bio-electronics. This generation of diamond based bio-electronic devices would contribute substantially to ushering in a paradigm shift for medical science, leading to vastly improved patient diagnosis, decrease of drug development costs and risks, and improved effectiveness of drug delivery and gene therapy programs through better timed and more customized solutions.

    Full Text Available Utilization of eco-font for office printing is one of sustainable, “green” printing concepts, which besides obvious economic benefits, as a result has a certain effect on environmental sustainability as well. The fundamental problem that this practice faces is decreased quality of text printed using eco-fonts comparing to those printed with regular fonts. The aim of this research is eco-font efficiency estimation, i.e. determination of toner usage reduction level of ink jet printed documents typed with this font type, as well as estimation of the extent humans perceive differences between text printed with eco-font and the one printed by its „non-eco“ equivalent. Combining instrumental measuring method and digital image analysis, it was found that this simple principle (eco-font utilization enables substantial toner usage reduction for an ink jet printing system, while visual test showed that visual experience of text printed using eco-font is sufficient. In addition, awareness of benefits that eco-font utilization brings, change users’ attitude towards eco-font quality.

    In order to manufacture an eco-friendly stud, the sheared pattern is designed by the Taguchi method and expanded by the side rolls. The seven geometrical shape of sheared pattern are considered in the structural and thermal analyses to select the best functional one in terms of the durability and fire resistance of dry wall. For optimizing the size of the sheared pattern chosen, the L9 orthogonal array and smaller-the-better characteristics of the Taguchi method are used. As the roll gap causes forming defects when the upper-and-lower roll type is adopted for expanding the sheared pattern, the side roll type is introduced. The stress and strain distributions obtained by the FEM simulation of roll-forming processes are utilized for the design of expanding process. The expanding process by side rolls shortens the length of expanding process and minimizes the cost of dies. Furthermore, the stud manufactured by expanding the sheared pattern of the web is an eco-friend because of the scrapless roll-forming process. In addition, compared to the conventionally roll-formed stud, the material cost is lessened about 13.6% and the weight is lightened about 15.5%.

    Surgical resection of epileptogenic foci is often a beneficial treatment for patients suffering debilitating seizures arising from intractable epilepsy [1], [2], [3]. Electrodes placed subdurally on the surface of the brain in the form of an ECoG array is one of the multiple methods for localizing epileptogenic zones for the purpose of defining the region for surgical resection. Currently, transcutaneous wires from ECoG grids limit the duration of time that implanted grids can be used for diagnosis. A wireless ECoG recording and stimulation system may be a solution to extend the diagnostic period. To avoid the transcutaneous connections, a 64-channel wireless silicon recording/stimulating ASIC was developed as the electronic component of a wireless ECoG array that uses SIROF electrodes on a polyimide substrate[4]. Here we describe two new ASIC devices that have been developed and tested as part of the on-going wireless ECoG system design.

    2018-04-01

    Full Text Available This study constructs a theory of eco-innovation in circular agri-business. Although previous studies have discussed eco-innovation in circular agri-business, they did not address eco-innovation from the perspective of a closed-loop sustainable supply chain. Hence, this study applied the fuzzy TOPSIS method to conduct the analysis and determine the interrelationship between eco-innovation and the closed-loop concept. The results are consistent with the theory and a significant improvement in terms of the decisive attributes. The findings suggest that improving water management, relationships with suppliers, knowledge sharing, environmental management systems, and new product and service development are the most effective and efficient ways to build eco-innovation in circular agri-business. The managerial and theoretical implications are discussed.

    Considering climate warming as an immediate threat for humanity, ecologists from the Eco-modernism movement not only approve but call for the presence of nuclear power in the energy mix. For them nuclear energy is a mature low-carbon energy that can be used to combine all renewable energies more efficiently. NGO like 'Environmental Progress', 'Energy for Humanity' or 'Save the Nukes' back the Eco-modernism movement. The Eco-modernism movement gathers unconventional ecologists who consider that modern technologies by using the eco-system more efficiently than previous technologies did, are a powerful tool to reduce the global impact of humane activities on the biosphere. The Eco-modernism movement is for agricultural intensification, the use of GMO, waste recycling and for increasing urbanization. (A.C.)

    2006-08-01

    This study adds new insights to the long-running corporate environmental-financial performance debate by focusing on the concept of eco-efficiency. Using a new database of eco-efficiency ratings, we analyze the relation between eco-efficiency and financial performance from 1997 to 2004. We report that eco-efficiency relates positively to operating performance and market value. Moreover, our results suggest that the market's valuation of environmental performance has been time variant, which may indicate that the market incorporates environmental information with a drift. Although environmental leaders initially did not sell at a premium relative to laggards, the valuation differential increased significantly over time. Our results have implications for company managers, who evidently do not have to overcome a tradeoff between eco-efficiency and financial performance, and for investors, who can exploit environmental information for investment decisions

    The development of entrepreneurships in the 21st century cannot occur without taking care of the natural environment. The article presents issues related to eco-innovation. Despite the opportunities offered by eco-innovations, implementation of such initiatives remains to lead to various difficulties. They vary across countries and sectors. The insufficient number of enterprises in Poland and other European countries implement adequate level of eco-innovations. The main aim of this paper is to indicate the causes of this status and activities aimed to develop eco-innovativeness. The benefits and risks connected with implementation of innovative products and technologies were also discussed. Furthermore, the advantages of and barriers to their implementation into companies were analysed. The entrepreneurs from the least eco-innovative countries emphasize serious barriers, including uncertain demand from the market, uncertain return on investment or too long a payback period for eco-innovation, lack of funds within the enterprise, insufficient access to existing subsidies and fiscal incentive. They are especially afraid of the financial risks, which raises uncertainty and leads to refraining from innovative initiatives. The possibilities were indicated for the entrepreneurs who face problems with the implementation of innovative solutions. Particular attention was paid to the European Union activities for the development of eco-innovations. Numerous programs supporting their implementation were indicated. The article also presents examples of eco-innovation in water and sewage enterprises. It was emphasized that planning of eco-innovative solutions should be based on comprehensive information about actual benefits and possibility of threats to the environment which can be caused by implementation of eco-innovations. The study presents the example of threats resulting from different methods of sewage sludge management. Copyright © 2017 Elsevier Inc. All rights

    The main conclusion in this report is that it is possible to make available about 14 TWh bio energy in Norway than what is used today to a charge that is located less than ca. 30 oere / kWh. Almost all this potential come from the forest and requires an increase in output up to the net sustained yield. Further 5 TWh may be available in the form of biogas at a cost that is both higher and have greater uncertainty than the fixed bio energy. It is set up a cost curve based on this work, which is quoted here. This reflects only the technical costs, and does not regard wages, commissions, taxes or fees. The value of alternative uses of biomass are not considered. The cost curve must therefore not be mixed with a supply curve. (eb)

  3. Bio-fuels - biohazard

    2008-01-01

    Politicians have a clear explanation for growing commodity prices. It is all the fault of speculators. It is easy to point the finger at an imaginary enemy. It is more difficult and from the point of view of a political career suicidal to admit one's mistakes. And there are reasons for remorse. According to studies prepared by the OECD and the World Bank bio-fuels are to be blame for high food prices. The bio-fuel boom that increases the demand for agro-commodities has been created by politicians offering generous subsidies. And so farming products do not end up on the table, but in the fuel tanks of cars in the form of additives. And their only efficiency is that they make food more expensive. The first relevant indication that environmentalist tendencies in global politics have resulted in shortages and food price increases can be found in a confidential report prepared by the World Bank. Parts of the report were leaked to the media last month. According to this information growing bio-fuel production has resulted in a food price increase by 75%. The theory that this development was caused by speculators and Chinese and Indian demand received a serious blow. And the OECD report definitely contradicted the excuse used by the politicians. According to the report one of the main reasons for growing food prices are generously subsidized bio-fuels. Their share of the increase of demand for agro-commodities in 2005 -2007 was 60% according to the study. (author)

  4. The Role of Interaction Patterns with Hybrid Electric Vehicle Eco-Features for Drivers' Eco-Driving Performance.

    2017-03-01

    The objective of the present research was to understand drivers' interaction patterns with hybrid electric vehicles' (HEV) eco-features (electric propulsion, regenerative braking, neutral mode) and their relationship to fuel efficiency and driver characteristics (technical system knowledge, eco-driving motivation). Eco-driving (driving behaviors performed to achieve higher fuel efficiency) has the potential to reduce CO 2 emissions caused by road vehicles. Eco-driving in HEVs is particularly challenging due to the systems' dynamic energy flows. As a result, drivers are likely to show diverse eco-driving behaviors, depending on factors like knowledge and motivation. The eco-features represent an interface for the control of the systems' energy flows. A sample of 121 HEV drivers who had constantly logged their fuel consumption prior to the study participated in an online questionnaire. Drivers' interaction patterns with the eco-features were related to fuel efficiency. A common factor was identified in an exploratory factor analysis, characterizing the intensity of actively dealing with electric energy, which was also related to fuel efficiency. Driver characteristics were not related to this factor, yet they were significant predictors of fuel efficiency. From the perspective of user-energy interaction, the relationship of the aggregated factor to fuel efficiency emphasizes the central role of drivers' perception of and interaction with energy conversions in determining HEV eco-driving success. To arrive at an in-depth understanding of drivers' eco-driving behaviors that can guide interface design, authors of future research should be concerned with the psychological processes that underlie drivers' interaction patterns with eco-features.

    , there is not enough biomass for 'everyone', not physically and not in terms of money to promote its use. This leads to the conclusion that any use of biomass for energy purposes will have to compare to the lost opportunity of using it for something else. In this perspective, the choice to use biomass for bio......-ethanol production will not lead to reduction but to increase in CO2 emission and fossil fuel dependency. Both first and second generation bio-ethanol suffer from a biomass-to-ethanol energy conversion efficiency as low as 30-40 %, and moreover external fossil fuels are used to run the conversion. There is only......, but they do not improve the energy balance enough for bio-ethanol to compete with alternative uses of the biomass. When using biomass to substitute fossil fuels in heat & power production, a close to 100% substitution efficiency is achieved. The best alternative for CO2 reduction and oil saving is, therefore...

  6. Concerning evaluation of eco-geochemical background in remediation strategy

    Science.gov (United States)

    Korobova, Elena; Romanov, Sergey

    2015-04-01

    The geochemical concept of biosphere developed by V.I. Vernadsky states the geological role of the living organisms in the course of their active chemical interaction with the inert matter (Vernadsky, 1926, 1960). Basing on this theory it is reasonable to suggest that coevolution of living organisms and their environment led to development of the dynamically stable biogeocenoses precisely adequate to their geochemical environment. Soil cover was treated by V.I. Vernadsky as a balanced bio-inert matter resulting from this interaction. Appearance of human mind and then a civilization led to global expansion of human beings, first able to survive in unfavorable geochemical conditions and then starting chemical transformation of the environment to satisfy the growing demands of mankind in food and energy. The residence in unfavorable environment and local contamination was followed by appearance of endemic diseases of plants, animals and man. Therefore zonal, regional and local chemical composition of the soil cover formed in natural conditions may be used for estimation of the optimum geochemical background, most adequate for the corresponding zonal biogeocenoses and species. Moreover, the natural geochemical background and technogenic fields have unequal spatial structure and this facilitates their identification that may be relatively easy realized in remediation strategy. On the assumption of the foregoing, the adequate methodical approach to remediation of technogenically affected areas should account of the interaction of the existing natural and the newly formed technogenic geochemical fields and include the following steps: 1) the study and mapping of geochemical structure of the natural geochemical background basing on soil maps; 2) the study of contaminants and mapping spatial distribution of technogenic releases; 3) construction of risk maps for the target risk groups with due regard to natural ecological threshold concentration in context of risk degree for

    With the advance of internet and wireless communication technology, the fields of ecology and environment have entered a new digital era with the amount of data growing explosively and big data technologies attracting more and more attention. The eco-environmental big data is based airborne and space-/land-based observations of ecological and environmental factors and its ultimate goal is to integrate multi-source and multi-scale data for information mining by taking advantages of cloud computation, artificial intelligence, and modeling technologies. In comparison with other fields, the eco-environmental big data has its own characteristics, such as diverse data formats and sources, data collected with various protocols and standards, and serving different clients and organizations with special requirements. Big data technology has been applied worldwide in ecological and environmental fields including global climate prediction, ecological network observation and modeling, and regional air pollution control. The development of eco-environmental big data in China is facing many problems, such as data sharing issues, outdated monitoring facilities and techno-logies, and insufficient data mining capacity. Despite all this, big data technology is critical to solving eco-environmental problems, improving prediction and warning accuracy on eco-environmental catastrophes, and boosting scientific research in the field in China. We expected that the eco-environmental big data would contribute significantly to policy making and environmental services and management, and thus the sustainable development and eco-civilization construction in China in the coming decades.

    Full Text Available Eco-certification has become an increasingly popular market-based tool in the endeavor to reduce negative environmental impacts from fisheries and aquaculture. In this study, we aimed at investigating which psychological consumer characteristics influence demand for eco-labeled seafood by correlating consumers’ stated purchasing of eco-labeled seafood to nine variables: environmental knowledge regarding seafood production, familiarity with eco-labels, subjective knowledge, pro-environmental self-identification, sense of personal responsibility, concern for negative environmental impacts from seafood production, perceived consumer effectiveness, gender and education. Questionnaires were distributed to consumers in Stockholm, Sweden, and the data were tested with multiple regression analysis using linear modeling and model averaging (n = 371. Two variables were the best predictors of stated purchasing of eco-labeled seafood: (i recognition and understanding of eco-labels for seafood (Marine Stewardship Council, Fish for Life, Aquaculture Stewardship Council and KRAV; and (ii concern for negative environmental impacts associated with seafood production. Meanwhile, consumer environmental knowledge was a weaker predictor. Results from this study suggest that strengthening the emotional component of consumer decision-making and improving the level of consumer familiarity with seafood eco-labels could stimulate more pro-environmental seafood consumption.

    Conventional investment theory suggests that socially responsible investing (SRI) leads to inferior, rather than superior, portfolio performance. Using Innovest's well-established corporate eco-efficiency scores, we provide evidence supporting the contrary. We compose two equity portfolios that differ in ecoefficiency characteristics and find that our high-ranked portfolio provided substantially higher average returns compared to its low-ranked counterpart over the period 1995-2003. Using a wide range of performance attribution techniques to address common methodological concerns, we show that this performance differential cannot be explained by differences in market sensitivity, investment style, or industry-specific components. We finally investigate whether this ecoefficiency premium puzzle withstands the inclusion of transaction costs scenarios, and evaluate how excess returns can be earned in a practical setting via a best-in-class stock selection strategy. The results remain significant under all levels of transactions costs, thus suggesting that the incremental benefits of SRI can be substantial

    Nano-bio interfaces are emerging from the convergence of engineered nanomaterials and biological entities. Despite rapid growth, clinical translation of biomedical nanomaterials is heavily compromised by the lack of comprehensive understanding of biophysicochemical interactions at nano-bio interfaces. In the past decade, a few investigations have adopted a combinatorial approach toward decoding nano-bio interfaces. Combinatorial nano-bio interfaces comprise the design of nanocombinatorial libraries and high-throughput bioevaluation. In this Perspective, we address challenges in combinatorial nano-bio interfaces and call for multiparametric nanocombinatorics (composition, morphology, mechanics, surface chemistry), multiscale bioevaluation (biomolecules, organelles, cells, tissues/organs), and the recruitment of computational modeling and artificial intelligence. Leveraging combinatorial nano-bio interfaces will shed light on precision nanomedicine and its potential applications.

    2016-12-01

    Full Text Available Eco-aware customers and stakeholders are demanding for a measurement that links environmental performance with other business operations. To bridge this seemingly measurement gap, this paper suggests ‘Eco-Ratio Analysis’ and proposes an approach for conducting eco-ratio analysis. It is argued that since accounting ratios function as a tool for evaluating corporate financial viability by management and investors, eco-ratio analysis should be brought to the fore to provide a succinct measurement about the linkage between environmental performance and conventional business performance. It is hoped that this suggestion will usher in a nuance debate and approach in the teaching, research and practice of environmental management and sustainability accounting

    Prasaja, Lukman Eka; Hadiyanto

    2018-02-01

    Eco-Efficiency emerged in the 1990s as a measure of "the efficiency that ecological sources use to meet human needs." As a tool in economic and environmental integration, Eco-efficiency needs to be promoted further so that regulation in government and industrial management can include it as an important instrument. This paper provides several approaches that can help various industries to develop effective eco-efficiency principles. The approach used is to maximize the role of the Steering Committee of the company's internal environment. Utilization of natural resources such as water, forests, mines and energy needs need to be balanced with Eco-Efficiency so that natural exploitation can be well controlled so that sustainable development aspired by the world can be realized.

    2013-07-01

    Full Text Available Local communities embracing the concept of Eco-industrial park are looking for some additional benefits for all the interested parties – both public and private: higher economic efficiency, the increase of competitivity by applying last minute technologies, generation of additional revenues through positive regulations at the community level, the creation of jobs, solving the conflict between economy and environment, diminishing the demand on the county infrastructure, decreasing the effects of pollution, using energy from regenerating sources and replacement materials. Communities and enterprises creating Eco-industrial parks will have common grounds for industrial development, which is much more competitive, more efficient and much cleaner than traditional industrial parks. Moreover, the new business niches will be open to recruitment or new incubators. Eco-industrial parks represent a special category compared to industrial parks, a category which is different from the classical ones due to the fact that they are designed in such a way so that they promote the collaboration between companies in order to reuse recyclable materials and green energy sources. A long-term vision must reflect the focus on the creation of collaboration networks between firms and the fact that an Eco-industrial park should be a business community, not only a mathematical sum of companies located in the same geographical area. The quality, continuity and interconnection of economic flows within the firms of an Eco-industrial park are important characteristics for the success of Eco-industrial networks. The following discussion tackles the way in which an Eco-industrial park is set-up: creating and implementing an Eco-industrial park in accordance with the principles of circular economy or transforming an already existing industrial park into an Eco- industrial park. The quality, the continuity, the number of interconnected firms, the flows of resources and the

  14. The Bio-Economy Concept and Knowledge Base in a Public Goods and Farmer Perspective

    Directory of Open Access Journals (Sweden)

    Otto Schmidt

    2012-05-01

    Full Text Available Currently an industrial perspective dominates the EU policy framework for a European bio-economy. The Commission’s proposal on the bio-economy emphasises greater resource-efficiency, largely within an industrial perspective on global economic competitiveness, benefiting capital-intensive industries at higher levels of the value chain. However a responsible bio-economy must initially address the sustainable use of resources. Many farmers are not only commodity producers but also providers of quality food and managers of the eco-system. A public goods-oriented bio-economy emphasises agro-ecological methods, organic and low (external input farming systems, ecosystem services, social innovation in multi-stakeholder collective practices and joint production of knowledge. The potential of farmers and SMEs to contribute to innovation must be fully recognised. This approach recognises the importance of local knowledge enhancing local capabilities, while also accommodating diversity and complexity. Therefore the bio-economy concept should have a much broader scope than the dominant one in European Commission innovation policy. Socio-economic research is needed to inform strategies, pathways and stakeholder cooperation towards sustainability goals.

    2016-07-01

    Full Text Available The importance of environmental consequences due to diverse substances that are emitted during the production of concrete is recognized, but environmental performance tends to be evaluated separately from the economic performance and durability performance of concrete. In order to evaluate concrete from the perspective of sustainable development, evaluation technologies are required for comprehensive assessment of environmental performance, economic performance, and durability performance based on a concept of sustainable development called the triple bottom line (TBL. Herein, an assessment method for concrete eco-efficiency is developed as a technique to ensure the manufacture of highly durable and eco-friendly concrete, while minimizing both the load on the ecological environment and manufacturing costs. The assessment method is based on environmental impact, manufacturing costs, and the service life of concrete. According to our findings, eco-efficiency increased as the compressive strength of concrete increased from 21 MPa to 40 MPa. The eco-efficiency of 40 MPa concrete was about 50% higher than the eco-efficiency of 24 MPa concrete. Thus eco-efficiency is found to increase with an increasing compressive strength of concrete because the rate of increase in the service life of concrete is larger than the rate of increase in the costs. In addition, eco-efficiency (KRW/year was shown to increase for all concrete strengths as mixing rates of admixtures (Ground Granulated Blast furnace Slag increased to 30% during concrete mix design. However, when the mixing rate of admixtures increased to 40% and 60%, the eco-efficiency dropped due to rapid reduction in the service life values of concrete to 74 (year/m3 and 44 (year/m3, respectively.

    It is now forty six years since the separate topics of friction, lubrication, wear and bearing design were integrated under the title 'Tribology' [Department of Education and Science, Lubrication (Tribology) Education and Research. A Report on the Present Position and Industry's Needs, HMSO, London, 1966]. Significant developments have been reported in many established and new aspects of tribology during this period. The subject has contributed to improved performance of much familiar equipment, such as reciprocating engines, where there have been vast improvements in engine reliability and efficiency. Nano-tribology has been central to remarkable advances in information processing and digital equipment. Shortly after widespread introduction of the term tribology, integration with biology and medicine prompted rapid and extensive interest in the fascinating sub-field now known as Bio-tribology [D. Dowson and V. Wright, Bio-tribology, in The Rheology of Lubricants, ed. T. C. Davenport, Applied Science Publishers, Barking, 1973, pp. 81-88]. An outline will be given of some of the developments in the latter field.

    Soil eco-toxicology provides a theoretical basis for ecological risk assessment of contaminated soils and soil pollution control. Research on eco-toxicological effects and molecular mechanisms of toxic substances in soil environment is the central content of the soil eco-toxicology. Eco-toxicological diagnosis not only gathers all the information of soil pollution, but also provides the overall toxic effects of soil. Therefore, research on the eco-toxicological diagnosis of soil pollution has important theoretical and practical significance. Based on the research of eco-toxicological diagnosis of soil pollution, this paper introduced some common toxicological methods and indicators, with the advantages and disadvantages of various methods discussed. However, conventional biomarkers can only indicate the class of stress, but fail to explain the molecular mechanism of damage or response happened. Biomarkers and molecular diagnostic techniques, which are used to evaluate toxicity of contaminated soil, can explore deeply detoxification mechanisms of organisms under exogenous stress. In this paper, these biomarkers and techniques were introduced systematically, and the future research trends were prospected.

    Ecological economics crossed extensively with some disciplines such as ecology, geography, economics, etc in China. And it is promoting the relevant disciplines to develop effectively in depth fields. The key research direction of eco-economic regionalizing is eco-economic space pattern, rule of territorial differentiation and eco-economic topological optimization. Based on GIS spatial analyze, the article elaborates the main characteristics and the problems of every eco-economic zones, districts and regions with the comprehensive geographical statistic data. The western eco-economic regionalizing was delimited by analyzing the superposition for ecological environment value and human actives value, refer to the topography and administrative boundary between provinces and the cities, the attachment of the regionalizing plans and territorial the continuity. There have several main indexes used in the regionalizing and the results to show the main character of each region, which comprise precipitation, temperature, primary production potential, while the population carrying capacity, and the index of water resources, land resources, landscape degradation, urbanization, and economic development, etc. To each type of eco-economic region, there are other analyzes respectively from the social, economic, and natural environment aspects. The result shows that there does now have serious economic development in western China, while the environmental problem still cannot be ignored.

  4. Eco-Efficiency Actions and Firm Growth in European SMEs

    Full Text Available This study investigates the effects of eco-efficiency actions on firm performance in terms of sales growth in an extensive sample of 11,336 small- and medium-sized enterprises (SMEs located in 28 European countries. Our empirical results suggest that not all eco-strategies are positively related to better performance, at least not in the short term. We found that European companies using renewable energies, and recycling or designing products that are easier to maintain, repair, or reuse, perform better. Those that aim to reduce water or energy pollution, however, seemed to show a negative correlation to firm growth. Our results also indicate that high investment in eco-strategies improves firm growth, particularly in new members that joined the EU from 2004 onwards. Finally, we observed a U-shaped relationship between eco-strategies and firm growth, which indicates that a greater breadth of eco-strategies is associated with better firm performance. However, few European SMEs are able to either invest heavily or undertake multiple eco-strategies, thus leaving room for policy interventions.

    Full Text Available An important goal of fisheries management is to ensure that fish stocks are harvested at sustainable levels of fishing pressure. However, the classical maximum sustainable yield theory and its derivatives have not worked for fisheries management. A number of mitigating measures have been suggested of which eco -labeling is one. An ecolabel on a fish product is a distinctive mark or statement indicating that it has been harvested in compliance with preset sustainability standards. This paper examines eco labeling in fisheries as the new strategy to achieve fisheries conservation and sustainability. It emphasizes the importance of fish as critical food resources and new approach to fisheries management through the use of certification programs. It considers the benefits and problems that may accrue from eco-certification of fish harvesting and trade practices in fisheries. This paper, attention is focused on examining the likely option for development of eco-labeling scheme in Nigeria. The paper concludes that the increase awareness amongst stakeholders of the potential role of eco-labeling in conservation and sustainability tools should be established.   Keywords: Fisheries management, fish, conservation, eco-certification

    Due to rapidly increasing greenhouse gas emissions, the transport sector is a key issue in any sustainability and climate strategy. Still, it is the one most difficult to deal with because of it's complexity and direct impact on everybody's life. Innovative transport technologies can significantly contribute to reducing emissions and energy use, but there is also a need for behavioural changes to turn down energy demand, especially in individual motorised transport. One of the most cost-effective measures in this field is Ecodriving, an energy efficient and road safety improving driving style. Nowadays, there are several stand-alone initiatives in Europe. But to strengthen Ecodriving and increase its market share it needs: - an overview of existing offers and facilities, - pilot projects with different target groups, - training courses (both for novice drivers and experienced road users), - quality standards, - scientific proof of the various benefits, - awareness raising and marketing. That's why ECO-DRIVING Europe has been initiated by the main stakeholders in Europe. It aims to change the behaviour of drivers by using technological developments, influencing legislation and supporting long term driving and mobility culture change. The Europe-wide ECO-DRIVING project (www.ecodrive.org ) tries to reach this goal by integrating Ecodriving into various policy fields such as energy, climate change, road safety, local environment, sustainable transport and legislation for driver licence procedures. By decreasing greenhouse gas emission by 10-20% compared to normal driving, Ecodriving can considerably contribute to reduce energy demand in transport and fight climate change.

    Emissions Trading started within EU at the beginning of 2005. It caused substantial changes to the business environment of energy companies and energy intensive industry. The planning of Emissions Trading is a complicated process and companies will need consulting, IT systems and other services. Emissions Trading introduces a new factor of production emission allowances, which are tradable commodities. In future, Emissions Trading emissions, emission allowances and the prices of emission allowances have to be considered during the fuel purchasing and the energy production planning. And the best possible knowledge of the own emissions balance and market situation has a monetary value when trading emission allowances. Allocation of emission allowances has done in each country according to National Allocation Plan (NAP), accepted by EU. Finland itself and thus also the Finnish companies will be net buyers of emission allowances in long run. That means commonly that the Finnish companies have to buy more allowances meaning some extra costs to the companies. That's why it is very important to develop and provide to the companies an innovatory emissions planning, follow-up, management and reporting systems. With good emission balance management the extra costs of Emissions Trading will be as low as possible. In ECO2 project, Empower together with Power-Deriva, developed Expert services, Emissions Balance Management and Reporting services and Risk Management services for Emissions Trading and needed software and tools for these services.

  12. BREEAM Green Leaf Eco-rating Program

    International Nuclear Information System (INIS)

    2001-01-01

    The environmental performance of buildings is measured for several reasons, the main one being that it can help owners decide where to invest their retrofit dollars to maximize the energy performance of their building and reduce operating costs. The buildings constructed in the 1950s and 1960s in North America are reaching obsolescence and will require major retrofits to improve their energy efficiency, particularly in the area of mechanical equipment. In addition to reducing operating costs, better maintenance and environmental management of buildings can also address issues such as comfort, health, indoor air quality and productivity. In order to accurately measure the environmental performance of a building, it is necessary to develop a comprehensive measuring and benchmarking tool that would allow occupants to compare the buildings' performance with others. In this pilot study, 6 high-rise multi-residential buildings were assessed for environmental performance using the BREEAM Green Leaf assessment method. The methodology originated in Canada and was developed by ECD Energy, Environment Canada and Terra Choice. It combines the BREEAM set of environmental issues with the Green Leaf Eco-Rating technique. The method covers occupant health, energy efficiency, resource efficiency, environmental responsibility and affordability. Operation and management issues are also taken into consideration. The buildings used in this study were located in various locations, ranging from inner city housing to city/suburban areas. 2 tabs., 17 figs

    NASICON frame work Na3V2(PO4)3 (NVP), wrapped by nitrogen and sulfur doped bio-carbon matrix derived from human hair (HHC) has been investigated for its anode behavior in SIBs. Basically, NVP is bestowed with a crystal structure of 3D open framework and a moderate theoretical capacity of 118 mAh g-1, which are the twin advantages and motivation behind the selection of this material. Prepared through a simple, scalable and facile method, the key problems associated with pristine NVP electrode material, such as inferior conductivity and severe volume change have been mitigated to a great extent through the formation of a composite containing HHC. Herein, HHC is a cheap and eco-friendly composite additive, obtained from a universal bio-waste, viz., human hair and hence NVP/HHC qualifies itself as a green composite. Interestingly, NVP/HHC-10 (in-situ) and NVP/HHC-20 (ex-situ) anodes show excellent electrochemical performance in terms of cycling stability up to 500 cycles and rate capability @ 2 A g-1, which are superior than similar category NVP anodes reported in the literature. Further, post cycling structure and morphology of NVP/HHC composite anodes evidence the appreciable stability bestowed with the select composition, which is found to get maintained upon extended cycles and even after rate capability test.

    This work constitutes a preliminary study in which the capacity of non-Saccharomyces yeasts isolated from ancient distilleries as bio-control agents against moulds and in the treatment of waste waters contaminated by heavy metals-i.e. bio-remediation-is shown. In the first control assays, antagonist effect between non-Saccharomyces yeasts, their extracts and supernatants against some moulds, analysing the plausible (not exhaustive) involved factors were qualitatively verified. In addition, two enzymatic degrading properties of cell wall plant polymers, quitinolitic and pectinolitic, were screened. Finally, their use as agents of bio-remediation of three heavy metals (cadmium, chromium and lead) was analysed semi-quantitatively. The results showed that all isolates belonging to Pichia species effectively inhibited all moulds assayed. Moreover, P. kudriavzevii is a good candidate for both bio-control and bio-remediation because it inhibited moulds and accumulated the major proportion of the three tested metals.

    Minimizing energy consumption is the effect of sustainable design technics as among many others: designing buildings with solar access and natural ventilation, using climate responsive design materials and effective insulation. Contemporary examples of zero-carbon cities: Masdar City, United Arab Emirates and Dongtan, China, confirm technical feasibility of renewable energy by implementation of solar PV and wind technologies. The ecological city - medium or high density urban settlement separated by greenspace causes the smallest possible ecological footprint on the surrounding countryside through efficient use of land and its resources, recycling used materials and converting waste to energy. This paper investigates the concept of energy sustainable cities, examines, how urban settlements might affect building energy design in eco-villages, eco-districts (e.g. Vauban, Freiburg in Germany, Bo01 Malmo in Sweden), and discuss the strategies for achieving Zero Emission Cities principles in densely populated areas. It is focused on low energy architectural design solutions which could be incorporated into urban settlements to create ecological villages, districts and cities, designed with consideration of environmental impact, required minimal inputs of energy, water, food, waste and pollution.

    Full Text Available In today's world, it is very necessary to understand the importance of being eco-friendly in every facet of our lives. The color “green” has healing power and denotes renewal, growth, and hope. “Eco-friendly dentistry” attempts to reduce the detrimental impact of dental practices on the environment and promote environmental awareness and sustainability to patients. This paper attempts to cover all possible aspects of making a dental practice eco-friendly, both in a dental perspective as well as a general perspective. While establishing an eco-friendly dental workplace, the dentist needs to assess his choices in planning the infrastructure and purchasing of equipment and dental materials. Eco-friendly dentistry is a newly evolving practice of dentistry, which encompasses a simultaneous devotion to sustainability, prevention, precaution, and a minimally invasive patient-centric, as well as global-centric treatment. There are two main avenues for implementing eco-friendly dentistry: (1 appropriate policy development and implementation and (2 dentists taking responsibility/ownership in the absence of policies and regulations. Although in some cases, it may take a little extra effort or money; dentists throughout the world are doing their best to reduce the environmental impact of the dental practice. Although the commitment of one small dental office cannot save the planet, certainly, the collective efforts of many small offices as well as large dental hospitals/colleges can ensure that dentists, at least, will not be responsible for destroying it. This article discusses various factors that can be incorporated into dental practice that can help make dentistry eco-friendly.

    After having indicated the various possible origins of biomass, this paper considers the issue of bio-energies, i.e., energies produced with biomass related to forest or agriculture production. Some indicators are defined (share of renewable energies, share of biomass in the energy production and consumption, number of production units). Stake holders are identified. Then, major and emerging trends are identified and discussed. The major trends are: development and diversification of renewable energies, development of bio-fuels with the support of incentive policies, prevalence of the wood-energy sector on the whole renewable energies, increase of surfaces dedicated to bio-fuels since the end of the 1990's, a French biogas sector which is late with respect to other countries. The emerging trends are: the important role of oil price in the development of bio-fuels, a necessary public support for the development of biogas, mobilization of research and development of competitiveness poles for bio-industries. Some prospective issues are also discussed in terms of uncertainties (soil availabilities, environmental performance of bio-fuels, available biomass resource, need of a technological advance, and evolution of energy needs on a medium term, tax and public policy). Three hypotheses of bio-energy evolutions are discussed

    Algae appear to be an emerging source of biomass for bio diesel that has the potential to completely displace fossil fuel. Two thirds of earth's surface is covered with water, thus alga e would truly be renewable option of great potential for global energy needs. This study discusses specific and comparative bio diesel quantitative potential of Cladophora sp., also highlighting its biomass (after oil extraction), pH and sediments (glycerine, water and pigments) quantitative properties. Comparison of Cladophora sp., with Oedogonium sp., and Spirogyra sp., (Hossain et al., 2008) shows that Cladophora sp., produce higher quantity of bio diesel than Spirogyra sp., whereas biomass and sediments were higher than the both algal specimens in comparison to the results obtained by earlier workers. No prominent difference in pH of bio diesel was found. In Pakistan this is a first step towards bio diesel production from algae. Results indicate that Cladophora sp., provide a reasonable quantity of bio diesel, its greater biomass after oil extraction and sediments make it a better option for bio diesel production than the comparing species.

    Environmental issues of personal care products have been met with little attention in the past. Monitoring data as well as preliminary environmental risk assessments indicate that some ingredients in personal care products might be relevant pollutants in the environment. Following the precautionary principle, eco-labelling is proposed as an effective tool for source control of one major group of personal care products, shampoos, shower gels and foam baths (SSBs). Eco-labelling is a soft, but effective market driven and product specific approach to lower discharge of environmentally detrimental substances. Products that fulfil the criteria proposed help to minimise the impact of SSBs on the environment. Available assessment tools for dangerous substances (e.g. current legislation on environmental risk assessments and classification, and labelling, eco-labelling criteria for similar products, the calculation of the critical dilution volume) were adapted and integrated into the criteria for the eco-labelling of SSBs. A short outline of the eco-labelling criteria developed for SSBs is provided. The basic criteria concern the effects of the substances discharged into the waste water during and after use. Products with an eco-label award may exclusively contain substances for which basic information about their effects on the environment is available. They may not contain persistent, bioaccumulating, toxic or ecotoxicological substances. In addition, the basic criteria include requirements for the container and consumer information. The basic criteria for eco-labelling SSBs are based on the actual state of science and are at the same time as simple and transparent as possible to ensure the best applicability. SSBs that comply with the described basic criteria can contribute to a lower chemical burden of waste water treatment plants and surface water. The proposal for basic criteria described should stimulate discussion on eco-labelling of SSBs. It should help to pass

    2007-03-01

    SOFT (Smooth OPC Fixing Technique) is a new OPC flow developed from the basic OPC framework. It provides a new method to reduce the computation cost and complexities of ECO-OPC (Engineering Change Order - Optical Proximity Correction). In this paper, we introduce polygon comparison to extract the necessary but possibly lost fragmentation and offset information of previous post-OPC layout. By reusing these data, we can start the modification on each segment from a more accurate initial offset. In addition, the fragmentation method in the boundary of the patch in the previous OPC process is therefore available for engineers to stitch the regional ECO-OPC result back to the whole post-OPC layout seamlessly. For the ripple effect in the OPC, by comparing each segment's movement in each loop, we much free the fixing speed from the limitation of patch size. We handle layout remodification, especially in three basic kinds of ECO-OPC processes, while maintaining other design closure. Our experimental results show that, by utilizing the previous post-OPC layout, full-chip ECO-OPC can realize an over 5X acceleration and the regional ECO-OPC result can also be stitched back into the whole layout seamlessly with the ripple effect of the lithography interaction.

    Full Text Available Despite technological advances in engines and fuels, the transportation sector is still one of the largest emitters of greenhouse gas (GHG. Driving patterns, including eco-driving techniques, are a complementary measure for saving GHG emissions. Most eco-driving studies so far have been conducted in large cities suffering chronic congestion problems. The aim of this research is therefore to analyse the potential of driver behaviour for reducing emissions in a small non-congested city. Driver performance parameters such as travel speeds, number of stops, revolutions per minute, and maximum acceleration-deceleration are also studied. The methodology is designed to measure the effect of both eco-driving and eco-routing under real traffic conditions. A campaign was carried out in the city of Caceres (Spain to collect data on various types of roads under different traffic conditions. This research concludes that eco-driving leads to CO2 savings on all routes and road types of 17% in gasoline engines and 21% in diesel, although travel times are increased by 7.5% on average. The shortest route is also the most ecological, regardless of the traffic volume and characteristics, implying that consumption in non-congested cities depends mainly on distance travelled rather than driving patterns in terms of number of stops, speed and acceleration.

    Full Text Available Uma análise detalhada apresenta o método argumentativo a contrario, característico do artigo "Existe a contracultura?", de Umberto Eco, como paradigmático do princípio estruturalista da constituição do sentido por meio de oposições semânticas. O artigo argumenta que muitos dos escritos de Eco podem ser lidos como aplicações do princípio estruturalista de que apenas diferenças ou oposições carregam significação. A evidência do modo como o pensamento de Eco está sob o encanto do princípio das oposições e da dialética da presença e da ausência é apresentada através do levantamento dos escritos gerais de Eco e também da inspeção das obras A estrutura ausente e Semiótica e filosofia da linguagem. Além disso, o artigo revela que o pensamento de Eco é igualmente atraído tanto por processos nos quais oposições anulam ou dissolvem a si próprias quanto pela crítica pós-estruturalista do pensamento estruturalista.

    This paper summarizes mineral waters as commercial products, and the manufacturing facilities thereof. The most widely used pattern of packaging mineral waters is to use either PET bottle or back-in box. The manufacturing process consists generally of: rough filtration of natural water, storage, activated carbon filtration, filtration, sterilization, ultrafine filtration, warm water bottling, capping, cooling, cartoning, storage, and shipment. The rough filtration removes sands. The activated carbon filtration removes water soluble organics. The sterilization is carried out under conditions of retaining the water at 75{degree}C for 15 seconds or retaining at 120 to 140{degree}C for 2 seconds. The ultrafine filtration uses a ceramic filter with a thickness of 0.2{mu}m. Sterilizing harmful microorganisms uses heating operation and filters to remove bacteria. An example may be cited that uses a bio-clean room for the purpose of controlling the harmful microorganisms. Subject microorganisms include a variety of viruses, rickettsia, bacteria, and fungi. The super-high performance (HEPA) filter used in the sterilization is demanded of collecting dusts with sizes of 0.3{mu}m or larger at a collection efficiency of 99.97% or higher. 3 refs., 4 figs., 1 tab.

    Full Text Available Ecological (eco taxes are promising mechanisms to enable eco-friendly decisions, but few people prefer them. In this study, we present a way in which eco-tax options may be communicated to general public to encourage their payment. Our implementation (called “information presentation” takes advantage of the non-linear relationship between eco-tax payments and CO2 emissions and the human reliance on the proportional-thinking heuristic. According to the proportional-thinking heuristic, people are likely to prefer a small eco-tax increase and judge larger eco-tax increases to cause proportionally greater CO2 emissions reductions. In an online study, participants were asked to choose between eco-tax increases in two problems: In one, a smaller eco-tax increase resulted in greater CO2 emissions reduction, while in the other, a smaller tax increase resulted in lesser CO2 emissions reduction. Although the larger eco-tax increase did not reduce CO2 emissions the most, across both problems, people judged larger eco-tax increases to cause proportionally greater reductions in CO2 emissions and preferred smaller tax increases. Thus, eco-tax policies would benefit by presenting information in terms of eco-tax increases, such that smaller eco-tax increases (which are more attractive and are likely to be chosen by people cause greater CO2 emissions reductions.

    Science.gov (United States)

    Mahdavinejad, M.; Bitaab, N.

    2017-08-01

    Search for high-performance architecture and dreams of future architecture resulted in attempts towards meeting energy efficient architecture and planning in different aspects. Recent trends as a mean to meet future legacy in architecture are based on the idea of innovative technologies for resource efficient buildings, performative design, bio-inspired technologies etc. while there are meaningful differences between architecture of developed and developing countries. Significance of issue might be understood when the emerging cities are found interested in Dubaization and other related booming development doctrines. This paper is to analyze the level of developing countries’ success to achieve smart-eco buildings’ goals and objectives. Emerging cities of West of Asia are selected as case studies of the paper. The results of the paper show that the concept of high-performance architecture and smart-eco buildings are different in developing countries in comparison with developed countries. The paper is to mention five essential issues in order to improve future architecture of developing countries: 1- Integrated Strategies for Energy Efficiency, 2- Contextual Solutions, 3- Embedded and Initial Energy Assessment, 4- Staff and Occupancy Wellbeing, 5- Life-Cycle Monitoring.

    2012-01-01

    As the world becomes increasingly urban, the need to quantify the effect of trees in urban environments on energy usage, air pollution, local climate and nutrient run-off has increased. By identifying, quantifying and valuing the ecological activity that provides services in urban areas, stronger policies and improved quality of life for urban residents can be obtained. Here we focus on two radically different models that can be used to characterize urban forests. The i-Tree Eco model (formerly UFORE model) quantifies ecosystem services (e.g., air pollution removal, carbon storage) and values derived from urban trees based on field measurements of trees and local ancillary data sets. Biome-BGC (Biome BioGeoChemistry) is used to simulate the fluxes and storage of carbon, water, and nitrogen in natural environments. This paper compares i-Tree Eco's methods to those of Biome-BGC, which estimates the fluxes and storage of energy, carbon, water and nitrogen for vegetation and soil components of the ecosystem. We describe the two models and their differences in the way they calculate similar properties, with a focus on carbon and nitrogen. Finally, we discuss the implications of further integration of these two communities for land managers such as those in Maryland.

    Eco-restoration of mine overburden (OB) or abandoned mine sites is a major environmental concern. In the present investigation, an integrated approach was used to rejuvenate a high-sulphur mine OB dumping site in the Tirap Collieries, Assam, India, which is situated in the Indo-Burma mega-biodiversity hotspot. A mine OB is devoid of true soil character with poor macro and micronutrient content and contains elevated concentrations of trace and heavy metals. Planting of herbs, shrubs, cover crops and tree species at close proximity leads to primary and secondary sere state succession within a period of 3 to 5 years. A variety of plant species were screened for potential use in restoration: herbs, including Sccharum spontaneum, Cymbopogon winterianus Jowitt (citronella), and Cymbopogon flexuosus (lemon grass) cover plants, including Mimosa strigillosa, M. striata, and M. pigra; shrubs, including Sesbania rostrata (dhaincha) and Cassia streata (cassia); and tree species, including Gmelina arborea (gomari) and Dalbergia sissoo (sissoo). Amendment with unmined soil and bio-organic matter was required for primary establishment of some plant species. Management of these plant species at the site will ensure long term sustainable eco-restoration of the coal mine-degraded land.

    Urban planning solutions and decisions have large-scale significance for ecological sustainability (eco-efficiency) the consumption of energy and other natural resources, the production of greenhouse gas and other emissions and the costs caused by urban form. Climate change brings new and growing challenges for urban planning. The EcoBalance model was developed to assess the sustainability of urban form and has been applied at various planning levels: regional plans, local master plans and detailed plans. The EcoBalance model estimates the total consumption of energy and other natural resources, the production of emissions and wastes and the costs caused directly and indirectly by urban form on a life cycle basis. The results of the case studies provide information about the ecological impacts of various solutions in urban development. (orig.)

    2017-01-01

    Full Text Available In his study The Open Work (1962 Umberto Eco commenced his long term exploration of the nature of interpreting an artwork. The author problematizes the question of freedom and the limits of artwork interpretation in the context of semiology and theory of semiotics. Although the contemporary debates on interpreting art focus on interpretation and interpreter, that is to say, on unconditional openness of the work, Eco reminds us of the other side of the interpreting process - controllability of the interpretative activity and limitations of reading in new meanings. The paper points to the various theoretical basis on which Eco propagates the dialectics between the form and openness of a work of art, in other words, between intentio operis and intentio lectoris. This position enables him to differentiate art from nonart, as well as to consider interpretation of a work of art not as a self-sufficing process, but from the point of view of human experience.

    Watershed eco-compensation is an effective way to solve conflicts over water allocation and ecological destruction problems in the exploitation of water resources. Despite an increasing interest in the topic, the researches has neglected the effect of water quality and lacked systematic calculation method. In this study we reviewed and analyzed the current literature and proposedatheoretical framework to improve the calculation of co-compensation standard.Considering the perspectives of the river ecosystems, forest ecosystems and wetland ecosystems, the benefit compensation standard was determined by the input-output corresponding relationship. Based on the opportunity costs related to limiting development and water conservation loss, the eco-compensation standard was calculated.In order to eliminate the defects of eco-compensation implementation, the improvement suggestions were proposed for the compensation standard calculation and implementation.

On these occasions each professor shows to the students the subject of the discipline, place and role that intellectual seizure of that object in the formation of their professional competence required by the exigencies of the time. Most teachers stop on the most important sources, sources of knowledge that young learners can turn to and would be better to turn. They indicate written sources, books, magazines and other publications available in classical libraries and add, especially now, the world’s largest library: the Internet. However, teachers advise students to seek permanently another source, a "book" - permanently opened, the book of reality that contains the most truth and what is very important - many problems waiting to be discovered and resolved. Leafing over "the first pages" of one of the "volumes" of this huge established "book", I found that the paradigm "Everything moves. Nothing stands still" as the paradigm "movement is absolute, and the repose - roughly" is far from having exhausted full knowledge of "everything".

    Full Text Available The recent global increase in the competitiveness of tourism has made the implementation of eco-innovations a differentiating element among both the destinations and companies in the sector, with quality management and contribution to sustainable development being increasingly valued. However, the eco-innovations that have been developed and implemented in tourist industries have rarely been studied. In this study, the eco-innovations that have been developed and implemented by 57 tourism businesses worldwide are analysed. The identified eco-innovations are classified by using different qualitative methodologies. The obtained results shed light on the limited development of eco-innovations in the tourism industry and the industry focuses mainly on product eco-innovations. Several examples by the tourist sub-industry and types of eco-innovation are analysed. Furthermore, this study provides practical information about measures that both businesses and governmental organisations can adopt to promote eco-innovation in the sector.

    2011-12-01

    Forests are a major terrestrial ecosystem providing multiple ecosystem services. However, the importance of forests is frequently underestimated from an economic perspective because of the externalities and public good properties of these services. Forest eco-compensation is a transfer mechanism that serves to internalize the externalities of forest ecosystem services by compensating individuals or companies for the losses or costs resulting from the provision of these services. China's current forest eco-compensation system is centered mainly on noncommercial forest. The primary measures associated with ecosystem services are (1) a charge on destructive activities, such as indiscriminate logging, and (2) compensation for individual or local activities and investments in forest conservation. The Compensation Fund System for Forest Ecological Benefits was first listed in the Forest Law of the People's Republic of China in 1998. In 2004, the Central Government Financial Compensation Fund, an important source for the Compensation Fund for Forest Ecological Benefits, was formally established. To improve the forest eco-compensation system, it is crucial to design and establish compensation criteria for noncommercial forests. These criteria should take both theoretical and practical concerns into account, and they should be based on the quantitative valuation of ecosystem services. Although some initial headway has been made on this task, the implementation of an effective forest eco-compensation system in China still has deficiencies and still faces problems. Implementing classification-based and dynamic management for key noncommercial forests and establishing an eco-compensation mechanism with multiple funding sources in the market economy are the key measures needed to conquer these problems and improve the forest eco-compensation system and China's forestry development in sequence.

    Environmental performance indicators (EPI) were discussed and a method by which companies can design indicators to help measure their progress toward greater eco-efficiency was presented. EPIs are quantitative measures of environmental performance. EPIs can measure one attribute, such as effluent released to water, or they can be a complex index. EPIs track impacts on the environment and provide information for decision making. The need for more eco-efficient companies, i.e. companies that produce useful goods and services while reducing their consumption of resources and while making efforts to reduce pollution, was emphasized

    The Genesis soil washing system is an integrated system of modular design allowing for maximum material handling capabilities, with optimized use of space for site mobility. The Surfactant Activated Bio-enhanced Remediation Equipment-Generation 1 (SABRE-1, Patent Applied For) modification was developed specifically for removing petroleum byproducts from contaminated soils. Scientifically formulated surfactants, introduced by high pressure spray nozzles, displace the contaminant from the surface of the soil particles into the process solution. Once the contaminant is dispersed into the liquid fraction of the process, it is either mechanically removed, chemically oxidized, or biologically oxidized. The contaminated process water is pumped through the Genesis Biosep (Patent Applied For) filtration system where the fines portion is flocculated, and the contaminant-rich liquid portion is combined with an activated mixture of nutrients and carefully selected bacteria to decompose the hydrocarbon fraction. The treated soil and dewatered fines are transferred to a bermed stockpile where bioremediation continues during drying. The process water is reclaimed, filtered, and recycled within the system

    2012-01-01

    Nature still outperforms the most powerful computers in routine functions involving perception, sensing and actuation like vision, audition, and motion control, and is, most strikingly, orders of magnitude more energy-efficient than its artificial competitors. The reasons for the superior performance of biological systems are subject to diverse investigations, but it is clear that the form of hardware and the style of computation in nervous systems are fundamentally different from what is used in artificial synchronous information processing systems. Very generally speaking, biological neural systems rely on a large number of relatively simple, slow and unreliable processing elements and obtain performance and robustness from a massively parallel principle of operation and a high level of redundancy where the failure of single elements usually does not induce any observable system performance degradation. In the late 1980's, Carver Mead demonstrated that silicon VLSI technology can be employed in implementing ''neuromorphic'' circuits that mimic neural functions and fabricating building blocks that work like their biological role models. Neuromorphic systems, as the biological systems they model, are adaptive, fault-tolerant and scalable, and process information using energy-efficient, asynchronous, event-driven methods. In this paper, some basics of neuromorphic electronic engineering and its impact on recent developments in optical sensing and artificial vision are presented. It is demonstrated that bio-inspired vision systems have the potential to outperform conventional, frame-based vision acquisition and processing systems in many application fields and to establish new benchmarks in terms of redundancy suppression/data compression, dynamic range, temporal resolution and power efficiency to realize advanced functionality like 3D vision, object tracking, motor control, visual feedback loops, etc. in real-time. It is argued that future artificial vision systems

    Full Text Available Bioplastics demand has been increased globally due to concerns regarding environmentally friendly consumption and production. Polylactic acid (PLA, polyhydroxyalkanoates (PHAs, and polybutylene succinate (PBS are promising bioplastics with bio-based feedstocks and property of biodegradability. They are produced by bacterial fermentation of sugars from carbohydrate sources. With flexibility in their properties, PLA, PHAs, and PBS can potentially substitute conventional plastics such as polypropylene (PP, polyethylene terephthalate (PET, and polystyrene (PS. This study aims at evaluating the environmental and economic sustainability of bioplastics production together with end-of-life (EOL options. The combination of environmental and economic indicators, eco-efficiency (E/E, was selected to investigate the performance of PLA, PHAs, and PBS from sugarcane and cassava in comparison with PP. The environmental impacts were determined using life cycle assessment. The product cost was used to represent the economic value. The E/E results showed that the environmental and economic sustainability could be enhanced with 100% mechanical recycling of all kinds of studied plastics. It is also important to highlight that mechanical recycling showed a better performance in terms of E/E than composting of bioplastics.

    Full Text Available El objetivo de este texto es reivindicar el papel de la creatividad teórica y política eco y ciber-feminista para ofrecer nuevos imaginarios sociales liberadores como el del cyborg, un nuevo icono. Esto último responde a la subversión epistemológica y metodológica de los ecofeminismos y los ciberfeminismos, opciones teórico-políticas que dislocan y desafían los estériles tópicos de los discursos misóginos. Tales estrategias subversivas son hoy lugar común de los estudios culturales feministas. La reflexión sobre la hibridación y la monstruosidad se incardina en las obras de diferentes autoras de referencia como Donna Haraway o Sadie Plant. La conclusión a la que llegamos es que la utopía de un mundo postgenérico, propuesto desde un ímpetu liberador ligado a las bio/ciber/tecnologías, no puede renegar de la ecología y de la cultura de la vida. Evaluamos, por lo tanto, el giro posthumanista desde criterios normativos igualitaristas y sostenibles.

    An eco-electrogenic engineered system (EES) was designed to mimic the functional role of natural aquatic ecosystems and evaluated their response to bio-electrogenic activity by cascadically interlinking three tanks with functionally diverse biota viz., floating macrophytes (Tank 1), submerged plants (Tank 2) and filter feeders (fish and snails) (Tank 3). Tank 1 showed efficient power generation (voltage (series): 0.86 V; current density (parallel): 37 mA/m 2 ) than Tank 2 (voltage (series): 0.76 V; current density (parallel): 34 mA/m 2 ) and Tank 3 (voltage (series): 0.65 V; current density (parallel): 22 mA/m 2 ). Integrating all three tanks enabled maximum power generation in parallel-series (P-S) connection (9.5 mW/m 2 ) than individual series and parallel connections (6.5/5 mW/m 2 ). Interaction of microbes and plants studied at the interface of electrochemical and engineering aspects illustrated the feasibility of EES as a self-sustainable system with innate diverse functional aquatic biota and rhizo-microbiome to produce bioelectricity.

  7. Eco-Dimensionality as a Religious Foundation for Sustainability

    Directory of Open Access Journals (Sweden)

    Susan Power Bratton

    2018-03-01

    Full Text Available Academics have critiqued the Abrahamic faiths, particularly Christianity, as inadequate to respond to today’s environmental dilemmas due to abstract theological qualities like the concept of a unified or transcendent God. Christianity and Islam are the earth’s most populous religions, however, and they are growing in the global south. A literature review finds that both indigenous and world religions develop strategies for environmental sustainability. Examples include: Amazonian fisheries, Islamic gardens, monastic forest management, Baptist LEED certified buildings, and Christian agrarian stewardship. These cases share a characteristic termed eco-dimensionality, defined as the integrative expression of environmental values, caretaking norms and sustainable practices in all aspects of religion, that recognizes and specifically adapts to keystone environmental processes and ecosystemic or geo-physical diversity. Religious eco-dimensionality incorporates: inventorying biota and ecosystems, recognizing environmental spatial and temporal dynamics at multiple scales, understanding communitarian and anti-communitarian human behaviors, structuring social networks, adopting sustainable technologies, and developing an integrative repertoire of religious symbols, aesthetic endeavors and ceremonies. Eco-dimensionality can evolve to address new issues. Negatively stereotyping faith traditions can inhibit constructive conversations concerning environmental issues and development of religious symbols and practices enhancing eco-dimensionality.

  18. Study for a simplified LCA methodology adapted to bio-products. Final report

    International Nuclear Information System (INIS)

    2009-01-01

    Agricultural resources form a renewable stock of raw materials that can be used for various purposes: food supply, production of energy (including biofuels), bio-products and bio-based construction materials. The use of agricultural resources to produce bio-products is expanding in France and throughout the world, partly due to the presumed advantages of these products towards the environment. In this context, ADEME (the French Environment and Energy Management Agency) commissioned a study for the development of a methodological framework to evaluate the environmental impacts of bio-products. This study was also in charge of the identification of areas of improvement for the 'Bilan Produit', an environmental assessment tool developed by ADEME, in order to allow a future integration of bio-products. The first step of this study consisted of a comparative review of the existing bio-products' LCA (Life Cycle Assessment). This review underlined a deep heterogeneity among the methodologies used, as well as a lack of transparency in the results displayed. In a second step of the project, all the methodological issues in the evaluation of bio-products were studied, and recommendations for the resolution of each one of them have been proposed. These critical analyses are presented in individual fact-sheets, which detail the specific issues of each question, facts from the bibliographic review, the results of the tests conducted on three bio-products, and finally the methodological recommendations to answer the question. This project showed that some methodological recommendations had to be specified depending on the objective of the LCA: eco-design, environmental labeling or comparative LCA. The work conducted also identified some necessary improvements to the Bilan Produit tool, which come under four categories: addition of the missing inventories, integration of metadata regarding the inventories, consideration for the specific end-of-life scenarios of bio-products, and

    2005-01-01

    Supplying water to the ecological environment with certain quantity and quality is significant for the protection of diversity and the realization of sustainable development. The conception and connotation of eco-environmental water requirements, including the definition of the conception, the composition and characteristics of eco-environmental water requirements, are evaluated in this paper. The classification and estimation methods of eco-environmental water requirements are then proposed. On the basis of the study on the Huang-Huai-Hai Area, the present water use, the minimum and suitable water requirement are estimated and the corresponding water shortage is also calculated. According to the interrelated programs, the eco-environmental water requirements in the coming years (2010, 2030, 2050) are estimated. The result indicates that the minimum and suitable eco-environmental water requirements fluctuate with the differences of function setting and the referential standard of water resources, and so as the water shortage. Moreover, the study indicates that the minimum eco-environmental water requirement of the study area ranges from 2.84×1010m3 to 1.02×1011m3, the suitable water requirement ranges from 6.45×1010m3 to 1.78×1011m3, the water shortage ranges from 9.1×109m3 to 2.16×1010m3 under the minimum water requirement, and it is from 3.07×1010m3 to 7.53×1010m3 under the suitable water requirement. According to the different values of the water shortage, the water priority can be allocated. The ranges of the eco-environmental water requirements in the three coming years (2010, 2030, 2050) are 4.49×1010m3-1.73×1011m3, 5.99×10m3?2.09×1011m3, and 7.44×1010m3-2.52×1011m3, respectively.

    Mosquito (Diptera: Culicidae) vectors are solely responsible for transmitting important diseases such as malaria, dengue, chikungunya, Japanese encephalitis, lymphatic filariasis and Zika virus. Eco-friendly control tools of Culicidae vectors are a priority. In this study, we proposed a facile fabrication process of poly-disperse and stable silver nanoparticles (Ag NPs) using a cheap leaf extract of Ichnocarpus frutescens (Apocyanaceae). Bio-reduced Ag NPs were characterized by UV-vis spectrophotometry, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction analysis (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The acute toxicity of I. frutescens leaf extract and green-synthesized Ag NPs was evaluated against larvae of the malaria vector Anopheles subpictus, the dengue vector Aedes albopictus and the Japanese encephalitis vector Culex tritaeniorhynchus. Compared to the leaf aqueous extract, Ag NPs showed higher toxicity against A. subpictus, A. albopictus, and C. tritaeniorhynchus with LC 50 values of 14.22, 15.84 and 17.26μg/mL, respectively. Ag NPs were found safer to non-target mosquito predators Anisops bouvieri, Diplonychus indicus and Gambusia affinis, with LC 50 values ranging from 636.61 to 2098.61μg/mL. Overall, this research firstly shed light on the mosquitocidal potential of I. frutescens, a potential bio-resource for rapid, cheap and effective synthesis of poly-disperse and highly stable silver nanocrystals.

    Full Text Available This study has two main approaches. First, it exploits the susceptibility of tomato cultivars as a prophylactic measure to detect auto resistance characters of the tested tomato varieties against Bemisia tabaci (Gennadius (Homoptera: Aleyrodidae. Secondly, it evaluates the efficacy of different bio-rational insecticides against B. tabaci under greenhouse conditions. The results exhibited a special significance in B. tabaci infestation suitability between the two tomato varieties with a high infestation significance found in the Shifa F1 hybrid tomato variety compared to the Savera F1 hybrid tomato variety in the first plantation period. Subsequently, in the second plantation period, there was a significant difference between the two tomato varieties. Bemisia tabaci showed a preference for the Shifa F1 hybrid over the Savera F1 hybrid tomato variety. These differences occurred during the 1st, 2nd, 4th, 6th, 7th, 8th, and 10th weeks. In the experimental trial for the efficacy of eco-friendly biorational insecticides, spinosad, azadirachtin, Beauveria bassiana and Metarhizium anisopliae, there were significant differences between the treated and untreated plants during the two plantation periods. A high efficacy of spinosad on the B. tabaci population was found. Bemisia tabaci infestation under all the applications was reduced from 50 to 94.61% for the two plantation periods. This obvious decrease in B. tabaci population increase attention to benefits of the different bio-rational insecticides.

  3. A distributed eco-hydrological model and its application

    Full Text Available Eco-hydrological processes in arid areas are the focus of many hydrological and water resources studies. However, the hydrological cycle and the ecological system have usually been considered separately in most previous studies, and the correlation between the two has not been fully understood. Interdisciplinary research on eco-hydrological processes using multidisciplinary knowledge has been insufficient. In order to quantitatively analyze and evaluate the interaction between the ecosystem and the hydrological cycle, a new kind of eco-hydrological model, the ecology module for a grid-based integrated surface and groundwater model (Eco-GISMOD, is proposed with a two-way coupling approach, which combines the ecological model (EPIC and hydrological model (GISMOD by considering water exchange in the soil layer. Water interaction between different soil layers is simply described through a generalized physical process in various situations. A special method was used to simulate the water exchange between plants and the soil layer, taking into account precipitation, evapotranspiration, infiltration, soil water replenishment, and root water uptake. In order to evaluate the system performance, the Heihe River Basin in northwestern China was selected for a case study. The results show that forests and crops were generally growing well with sufficient water supply, but water shortages, especially in the summer, inhibited the growth of grass and caused grass degradation. This demonstrates that water requirements and water consumption for different kinds of vegetation can be estimated by considering the water-supply rules of Eco-GISMOD, which will be helpful for the planning and management of water resources in the future.

    As being the heartlands of international trade, sea ports are the junction points of land and sea routes. The growth of global trade has led to the development of number and capacity as well as the service quality of ports. The policies and procedures applied during construction, operation and development of ports under development with environmental considerations scope has evolved in accordance with the needs of global trends. Although maritime transportation provides the most ecofriendly transportation method, the reduction of potential environmental threats and continuous improvement of ports and their vicinity is paramount from environmental concerns with regards to the international environmental standards. In the context of the study, national and international legal regulations governing the control of the environmental impacts of the activity groups causing pollution in Turkey based sea ports were viewed. In addition, the models applied during the measurement and documentation of environmental impacts were investigated. The most important aspects in terms of the effectiveness of the environmental management models are legal regulations. However, the standards applied at the ports without any legal obligation, such as EcoPorts applications, ISO 14001 standard, and the EMAS (Eco-Management and Audit Scheme) were sought in the scope of the study. The boundaries of the study were determined as the EU based Environmental Management Systems and the Green Port/Eco Port Project which is being administered by the Turkish Ministry of Transport, Maritime and Communication. “Marport”, which is Turkey’s first certified Green Port / Eco Port is designated as the experimental study site. In addition, the provisions in the ports of ESPO member countries are approached in order to compare the effectiveness and applicability of Green Port / Eco Port Project.

    We present eco-genetic modeling as a flexible tool for exploring the course and rates of multi-trait life-history evolution in natural populations. We build on existing modeling approaches by combining features that facilitate studying the ecological and evolutionary dynamics of realistically structured populations. In particular, the joint consideration of age and size structure enables the analysis of phenotypically plastic populations with more than a single growth trajectory, and ecological feedback is readily included in the form of density dependence and frequency dependence. Stochasticity and life-history trade-offs can also be implemented. Critically, eco-genetic models permit the incorporation of salient genetic detail such as a population's genetic variances and covariances and the corresponding heritabilities, as well as the probabilistic inheritance and phenotypic expression of quantitative traits. These inclusions are crucial for predicting rates of evolutionary change on both contemporary and longer timescales. An eco-genetic model can be tightly coupled with empirical data and therefore may have considerable practical relevance, in terms of generating testable predictions and evaluating alternative management measures. To illustrate the utility of these models, we present as an example an eco-genetic model used to study harvest-induced evolution of multiple traits in Atlantic cod. The predictions of our model (most notably that harvesting induces a genetic reduction in age and size at maturation, an increase or decrease in growth capacity depending on the minimum-length limit, and an increase in reproductive investment) are corroborated by patterns observed in wild populations. The predicted genetic changes occur together with plastic changes that could phenotypically mask the former. Importantly, our analysis predicts that evolutionary changes show little signs of reversal following a harvest moratorium. This illustrates how predictions offered by

  6. Eco-cities as an Assemblage of Worlding Practices

    2015-09-01

    Full Text Available Eco-cities are gaining attention in policy and academic circles over the past few years. Yet they pose difficulties as objects of study since they have been diversely defined and implemented. This paper argues that eco-cities are better understood as an assemblage of worlding practices. Combining these two concepts foregoes the emphasis on the eco-city’s physical structures and focuses more on its policy environment and its relations with other locations. The case study being examined is the Philippine’s Clark Green, the country’s first eco-city project. Its main proponent is an independent government agency, the Bases Conversion and Development Authority (BCDA, tasked with developing former military locations for civilian uses. Their vision is to create a world-class project built by international stakeholders in order to elevate the status of the Philippines and the Filipinos. They have chosen to emulate the Songdo International Business District in South Korea as their benchmark model. Not only are they adopting the ideas of a smart city but also similar strategies to enter the international education and logistics industries. The paper will show how the BCDA uses the eco-city idea as a tool to enter various national and international discourses that extend beyond the project’s geographical boundaries. Yet the strategies and visions of an independent government-owned corporation are tempered by challenges from local stakeholders, conflicting national priorities, and failures from similar policies applied elsewhere. The paper highlights the need for worlding projects to be embedded in their own national context for greater policy coordination.

  7. Eco-evolutionary spatial dynamics in the Glanville fritillary butterfly.

    2011-08-30

    Demographic population dynamics, gene flow, and local adaptation may influence each other and lead to coupling of ecological and evolutionary dynamics, especially in species inhabiting fragmented heterogeneous environments. Here, I review long-term research on eco-evolutionary spatial dynamics in the Glanville fritillary butterfly inhabiting a large network of approximately 4,000 meadows in Finland. The metapopulation persists in a balance between frequent local extinctions and recolonizations. The genetic spatial structure as defined by neutral markers is much more coarse-grained than the demographic spatial structure determined by the fragmented habitat, yet small-scale spatial structure has important consequences for the dynamics. I discuss three examples of eco-evolutionary spatial dynamics. (i) Extinction-colonization metapopulation dynamics influence allele frequency changes in the phosphoglucose isomerase (Pgi) gene, which leads to strong associations between genetic variation in Pgi and dispersal, recolonization, and local population dynamics. (ii) Inbreeding in local populations increases their risk for extinction, whereas reciprocal effects between inbreeding, population size, and emigration represent likely eco-evolutionary feedbacks. (iii) Genetically determined female oviposition preference for two host plant species exhibits a cline paralleling a gradient in host plant relative abundances, and host plant preference of dispersing females in relation to the host plant composition of habitat patches influences immigration (gene flow) and recolonization (founder events). Eco-evolutionary spatial dynamics in heterogeneous environments may not lead to directional evolutionary changes unless the environment itself changes, but eco-evolutionary dynamics may contribute to the maintenance of genetic variation attributable to fluctuating selection in space and time.

    Full Text Available AbstractBio-nanopatterning of surfaces is a very active interdisciplinary field of research at the interface between biotechnology and nanotechnology. Precise patterning of biomolecules on surfaces with nanometre resolution has great potential in many medical and biological applications ranging from molecular diagnostics to advanced platforms for fundamental studies of molecular and cell biology. Bio-nanopatterning technology has advanced at a rapid pace in the last few years with a variety of patterning methodologies being developed for immobilising biomolecules such as DNA, peptides, proteins and viruses at the nanoscale on a broad range of substrates. In this review, the status of research and development are described, with particular focus on the recent advances on the use of nanolithographic techniques as tools for biomolecule immobilisation at the nanoscale. Present strengths and weaknesses, as well future challenges on the different nanolithographic bio-nanopatterning approaches are discussed.

    The specific bio-species and their spatial patterns play crucial roles in regulating eco-hydrologic process, which is significant for large-scale habitat promotion and vegetation restoration in many dry-land ecosystems. Such effects, however, are not yet fully studied. In this study, 12 micro-plots, each with size of 0.5 m in depth and 1 m in length, were constructed on a gentle grassy hill-slope with a mean gradient of 8° in a semiarid loess hilly area of China. Two major bio-crusts, including mosses and lichens, had been cultivated for two years prior to the field simulation experiments, while physical crusts and non-crusted bare soils were used for comparison. By using rainfall simulation method, four designed micro-patterns (i.e., upper bio-crust and lower bare soil, scattered bio-crust, upper bare soil and lower bio-crust, fully-covered bio-crust) to the soil hydrological response were analyzed. We found that soil surface bio-crusts were more efficient in improving soil structure, water holding capacity and runoff retention particularly at surface 10 cm layers, compared with physical soil crusts and non-crusted bare soils. We re-confirmed that mosses functioned better than lichens, partly due to their higher successional stage and deeper biomass accumulation. Physical crusts were least efficient in water conservation and erosion control, followed by non-crusted bare soils. More importantly, there were marked differences in the efficiency of the different spatial arrangements of bio-crusts in controlling runoff and sediment generation. Fully-covered bio-crust pattern provides the best option for soil loss reduction and runoff retention, while a combination of upper bio-crust and lower bare soil pattern is the least one. These findings are suggested to be significant for surface-cover protection, rainwater infiltration, runoff retention, and erosion control in water-restricted and degraded natural slopes.

    The bio-environment has been the single most important correlation in human history and can successfully promote international co-operational co-operation and understanding. With the construction of a network for collaboration, the 'Danube Countries' can come together in celebration of their culture and heritage. As the Danube flows from the Black Forest to the Black Sea, it carries messages of peace, hope and co-operation. Applying these messages to every endeavour can improve our quality of life and lead to a brighter future. Since its inception in 1985, the Bio politics International Organization (B.I.O.) has been labouring to raise awareness of the urgent need to instate a new system of norms and principles, compatible with sound environmental management and with the most important task of ensuring global literacy on environmental issues. Along with critically re-assessing the concept of profit, the goal is to adopt a system of bio centric values, where respect for the bio-environment will govern our every action and thought

    Full Text Available Annually, it is estimated that about 4 billion units of consumer electronics for mobile communications are produced worldwide. This could lead to various ecological imbalances unless the design and disposal of the products are handled optimally. To illustrate how industry looks at and responds to the increasing social awareness, this article describes how sustainability is successfully implemented in practice at a large Chinese company, developing and producing various kinds of electronic products used for communication. It also describes how a variety of eco-innovations and business models contribute to reducing the environmental impact; for example, through increased recovery and recycling. A new kind of eco-design procedure is presented along with a new methodology which shows how a mobile phone gradually becomes more sustainable from one generation to the next. The issues with and set-up of new eco-labeling schemes for mobile phones, eco-rating, is described in detail. The conclusion is that due to high competition between companies, the industry acts resourcefully and a lot is done to the save the ecological environment.

    2009-11-01

    Bio-mimetic engineering or bio-mimetics is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology (from Wikipedia). The concept itself is old, but successful developments have been made recently, especially in the research field of flow control. The objective of flow control based on the bio-mimetic approach is to develop novel concepts for reducing drag, increasing lift and enhancing aerodynamic performance. For skin friction reduction, a few ideas have been suggested such as the riblet from shark, compliant surface from dolphin, microbubble injection and multiple front-body curvature from penguin, and V-shaped protrusion from sailfish. For form drag reduction, several new attempts have been also made recently. Examples include the V-shaped spanwise grooves from saguaro cactus, overall shape of box fish, longitudinal grooves on scallop shell, bill of swordfish, hooked comb on owl wing, trailing-edge protrusion on dragonfly wing, and fillet. For the enhancement of aerodynamic performance, focuses have been made on the birds, fish and insects: e.g., double layered feather of landing bird, leading-edge serration of humpback-whale flipper, pectoral fin of flying fish, long tail on swallowtail-butterfly wing, wing flapping motion of dragonfly, and alula in birds. Living animals adapt their bodies to better performance in multi purposes, but engineering requires single purpose in most cases. Therefore, bio-mimetic approaches often produce excellent results more than expected. However, they are sometimes based on people's wrong understanding of nature and produce unwanted results. Successes and failures from bio-mimetic approaches in flow control will be discussed in the presentation.

    Full Text Available Mounting experimental and theoretical results indicate that neural systems are poised near a critical state. In human subjects, however, most evidence comes from functional MRI studies, an indirect measurement of neuronal activity with poor temporal resolution. Electrocorticography (ECoG provides a unique window into human brain activity: each electrode records, with high temporal resolution, the activity resulting from the sum of the local field potentials of sim 10^5 neurons. We show that the human brain ECoG recordings display features of self-regulated dynamical criticality: dynamical modes of activation drift around the critical stability threshold, moving in and out of the unstable region and equilibrating the global dynamical state at a very fast time scale. Moreover, the analysis also reveals differences between the resting state and a motor task, associated with increased stability of a fraction of the dynamical modes.

    Among the problems common to all mankind, which solutions influence the prospects of civilization, the problem of ecological situation monitoring takes very important place. Solution of this problem requires specific methodology based on eco-analytical comprehension of global issues. Eco-analytical methodology should help searching for the optimum balance between environmental problems and accelerating scientific and technical progress. The fact that Governments, corporations, scientists and nations focus on the production and consumption of material goods cause great damage to environment. As a result, the activity of environmentalists is developing quite spontaneously, as a complement to productive activities. Therefore, the challenge posed by the environmental problems for the science is the formation of geo-analytical reasoning and the monitoring of global problems common for the whole humanity. So it is expected to find the optimal trajectory of industrial development to prevent irreversible problems in the biosphere that could stop progress of civilization.

    Based on the assessment method of environmental vulnerability constructed by SOPAC and UNEP, this paper constructed an indicator system from three sub-themes including hazard, resistance, and damage to assess the eco-environmental vulnerability of Hainan Island. The results showed that Hainan Island was suffering a middling level eco-environmental hazard, and the main hazards came from some intensive human activities such as intensive agriculture, mass tourism, mining, and a mass of solid wastes thrown by islanders and tourists. Some geographical characters such as larger land area, larger altitude range, integrated geographical form, and abundant habitat types endowed Hainan Island higher resistance to environmental hazards. However, disturbed by historical accumulative artificial and natural hazards, the Island ecosystem had showed serious ecological damage, such as soil degradation and biodiversity loss. Comprehensively considered hazard, resistance, damage, and degradation, the comprehensive environmental vulnerability of the Island was at a middling level. Some indicators showed lower vulnerability, but some showed higher vulnerability.

    Full Text Available Tourism is extremely interacted with the environment. Taking into account that tourism uses the space and related resources, it seems right to pay for the damages caused to the environment. This is the basis of the tourist spatial eco rent. The paper evaluates the space and resources used by tourism as the basis for the introduction of the tourism eco-rent in the area of Makarska Riviera, a traditional tourism destination. It is divided into three main spatial units: urban areas, bathing zone (beaches, Biokovo Park of Nature. According to natural and geographical reasoning, a number of zones with different spatial values within each spatial unit has been identified. Each unit, i.e. zone was evaluated according to various criteria relevant to the evaluation of space for tourism and tourism development purposes. Having ranked zones within each unit, using the multiriteria ranking method PROMETHEE II, comparative analysis of the obtained results was carried out as well.

    This article takes a look at the various eco-power offers that can currently be found on the Swiss electricity market. Various electricity utilities offer ecologically produced power in various qualities under several different names. These range from pure solar power through to various mixes of solar, wind and hydro power. The varying marketing approaches used are discussed. Local utilities have the most success in selling eco-power, whereas a large Swiss supermarket chain had difficulty selling its customers certificates for renewable electricity. This, according to the chain's speaker, was due to the difficulty of explaining the relationship between production certificates and the actual power drawn from the wall socket. The offers of various utilities and independent power producers are looked at and discussed with those responsible

    2009-09-01

    Full Text Available The immediate effect of energy consumption on environment quality is its deterioration. Gas and dust emissions, as products of coal, mazut (heavy fuel oil or natural gas combustion, continually pollute the atmosphere and have a global effect on climate changes, ozone damage, acid rains, disappearing of sensitive ecosystems, etc. This, directly or indirectly, brings about pollution of soil and fresh water, since energy life cycle begins with mines, oil and gas deposits, and ends with mechanical operations, heating and cooling with the restoration of thermal energy back into the atmosphere. In order to anticipate these negative processes, it is necessary to conduct an array of eco innovations in the entire life cycle of final energy. What this paper will show, on the example of communally-industrial energetics, is methodology of research and realization of eco innovations, as well as assessment of effects on improvement of energetic efficiency, quality of the environment and human life.

    Ghignoni, E.

    1999-01-01

    The paper tackles with the critical discussion of the eco tax double dividend theory. It is built up a theoretical and empirical analysis on short and long run effects of changes in real prices of energetic inputs on the use of polluted sources and labour, as well as on short and long run effects of changes in real labour cost on the use of labour and energy. At that purpose Johansen's procedure allows to get a structural multivariate model of dynamic relationships among the variables enclosed in the data set of a production function with labour and energy. This model is submitted to a dynamic simulation and results suggest that the introduction of an eco tax coupled with a decreasing in real labour cost would have uncertain and not leasing effects on the reduction of pollution coming from the utilisation of energetic sources and very limited effects on employment [it

    2012-01-01

    Bio-compatible polyelectrolyte sub-micron micro-capsules have been developed and applied to deliver fluorescent dyes into zebrafish larvae heart via direct injection in pericardium in vivo. The capsules shell performed as a membrane is impermeable for florescence dyes suspended within the capsules and is permeable for the external environment. Thus, the direct contact of fluorescence dyes with cells/tissues is excluded and the issues associated with the toxicity of fluorescence dyes and their bio-compatibility can be omitted. The hybrid laser-scanning imaging system combined with the fluorescent microscope has been used to monitor the paths of micro-capsules within zebrafish circulation system. We demonstrate that micro-capsules circulate in tissues, including brain and trunk, with no blood flow disruptions or any other deleterious effect on its cardiac function. The developed approach has a great potential to use of encapsulated bio-markers as a diagnostic tool in vascular biology and medicine as well as for monitoring of aquatic pollution and ecological risk assessment in eco-toxicological studies

    This paper analyzes a set of selected German and French cities' performance in terms of the relative behavior of their eco-efficiencies, computed as the ratio of their gross domestic product (GDP) over their CO 2 emissions. For this analysis, eco-efficiency scores of the selected cities are computed using the data envelopment analysis (DEA) technique, taking the eco-efficiencies as outputs, and the inputs being the energy consumption, the population density, the labor productivity, the resource productivity, and the patents per inhabitant. Once DEA results are analyzed, the Malmquist productivity indexes (MPI) are used to assess the time evolution of the technical efficiency, technological efficiency, and productivity of the cities over the window periods 2000 to 2005 and 2005 to 2008. Some of the main conclusions are that (1) most of the analyzed cities seem to have suboptimal scales, being one of the causes of their inefficiency; (2) there is evidence that high GDP over CO 2 emissions does not imply high eco-efficiency scores, meaning that DEA like approaches are useful to complement more simplistic ranking procedures, pointing out potential inefficiencies at the input levels; (3) efficiencies performed worse during the period 2000-2005 than during the period 2005-2008, suggesting the possibility of corrective actions taken during or at the end of the first period but impacting only on the second period, probably due to an increasing environmental awareness of policymakers and governors; and (4) MPI analysis shows a positive technological evolution of all cities, according to the general technological evolution of the reference cities, reflecting a generalized convergence of most cities to their technological frontier and therefore an evolution in the right direction.

    Background Access to the information concerning blood safety is essential for managing problems and overcoming the challenges that are faced in any given region. Information on the availability and safety of blood in countries of the Economic Cooperation Organisation (ECO) is largely lacking. To address this problem, the Iranian Blood Transfusion Organisation, in collaboration with other ECO member states, initiated a research project in 2009 to collect, analyse and compare statistics on blood safety in the region. Materials and methods A modified and summarised version of the Global Database on Blood Safety (GDBS) questionnaire was used to collect data. The questionnaire was sent to all ten countries in the ECO region. The heads of the national transfusion services or focal points were requested to complete the form. Related literature and websites were also reviewed. Results Only three countries (Afghanistan, Iran and Turkey) completed the questionnaire, while other countries provided their available data on some parts of the questionnaire. The number of donations per year varied from 5 to 27/1,000 population. The rate of donors positive for human immunodeficiency virus ranged from 0.003% to 0.2%. The rate of donors positive for hepatitis C virus antibody varied from 0.05% to 3.9% while that of hepatitis B virus surface antigen ranged from 0.15% to 3.91% respectively. Discussion There is very clear diversity in blood transfusion services among ECO member states. Most countries in the region do not have a data-recording system. It is generally estimated that the need for blood is much higher than the supply in this region. Deficiencies in donor screening and a high prevalence of transfusion-transmitted infections are other important challenges. PMID:26192779

  20. The reality of fiction: the ECO by Mathias Goeritz

    2016-05-01

    Full Text Available Abstract This article covers the full biography of a building, the Experimental Museum El Eco, designed by Germanborn and Mexican émigré artist and architect Mathias Goeritz. It provides an approach intersecting the biography of the author, the history of the building, and prominent  individuals of the two cultural traditions, German and Mexican, who  participated in the creation of a very special and unique building: El Eco. On the one hand, the ethics of Expressionism, the interest in  non-European art, the cult of primitivism and the aesthetic system of the  pair of concepts abstraction-empathy, all stemming from German culture. On the other, the pantheistic religiosity of landscape, zoomorphism and anthropomorphism, the interest in masks, and the aesthetics of  monumental scale, stemming from pre-Cortesian Mexican culture. Taking  the stance of intertwining Mathias Goeritz parcours with those of individuals and issues from his German past and his Mexican future – highlighting the figures of Wilhelm Worringer, Paul Westheim, Luis Barragán, Edmundo O'Gorman, and Ida Rodríguez Prampolini – this article proposes a return  trip from fiction to reality, following in the footsteps of the author and  comparing them with the pathway of the very building El Eco.

    2016-07-01

    Purpose - Water scarcity will further stress on available water systems and decrease the security of water in many areas. Therefore, innovative methods to minimize industrial water usage and waste production are of paramount importance in the process of extending fresh water resources and happen to be the main life support systems in many arid regions of the world. This paper demonstrates that there are good opportunities for many industries to save water and decrease waste water in softening process by substituting traditional with echo-friendly methods. The patented puffing method is an eco-efficient and viable technology for water saving and waste reduction in lime softening process. Design/methodology/approach - Lime softening process (LSP) is a very sensitive process to chemical reactions. In addition, optimal monitoring not only results in minimizing sludge that must be disposed of but also it reduces the operating costs of water conditioning. Weakness of the current (regular) control of LSP based on chemical analysis has been demonstrated experimentally and compared with the eco-efficient puffing method. Findings - This paper demonstrates that there is a good opportunity for many industries to save water and decrease waste water in softening process by substituting traditional method with puffing method, a patented eco-efficient technology. Originality/value - Details of the required innovative works to minimize industrial water usage and waste production are outlined in this paper. Employing the novel puffing method for monitoring of lime softening process results in saving a considerable amount of water while reducing chemical sludge.

    Full Text Available As national mega projects, the Suez Canal Area Development Project and New Suez Canal have logistically imposed two main questions. First, how the project can spot the preferred solution for balancing the business and environmental concerns? Second, how the project can enhance the trade-off between those two dimensions. In order to answer these two questions, the efficient frontier between the profitability and the environmental impact needs to be investigated. Three Levels of Thinking has to be applied. In Marlog 2, the Operational Thinking has been discussed using different supply chain approaches including SCOR and Lean Thinking. In Marlog 3, the Tactical Thinking has been explained for global growth opportunities including thinking process and value chain philosophy. This year, the Strategic Thinking approach will be discussed for improving the Eco-efficiency in logistics clusters with the application for the Suez Canal Logistics Corridor project.  The main purpose of this paper is to explore the eco-efficiency solution and the concept of eco-topology for the national mega project to transfer the Suez Canal region into a global logistics corridor.

  4. Certifying the commons: eco-certification, privatization, and collective action

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available We examine new dynamics of privatization and collective action in common pool resource situations facilitated by the nonstate multistakeholder institutions of the Marine Stewardship Council (MSC, the global leader in sustainability certification for wild caught seafood. Through a review of the literature and two case studies of fishing cooperatives in Baja California Sur, Mexico and on Fogo Island in the Canadian Province of Newfoundland and Labrador (NL, we advance two interrelated arguments. First, certification and eco-labeling institutions privatize fisheries governance in largely unexamined ways through the injection of new forms of exclusive rights or privileges into common pool resource situations already complicated by access and property privileges, creating conditions for confusion and conflict as well as cooperation. Second, the MSC whole stock definition of sustainability places greater demands on certification clients for engaging in collective action by encouraging coordination over all social extractions from targeted fish stocks. Although rules encouraging collective action in common pool situations militate against the narrow private capture of certificate and eco-label rights, they also undermine the ability of small-scale and community-based fisheries that are embedded in larger unhealthy fishery contexts to acquire the right to the MSC stamp of sustainability. We conclude that MSC certification and eco-labeling create new institutions of private property rights and collective action, which can result in exclusionary practices, inclusionary collective action, or both. Much will depend on the specific common pool context and history of the fishery.

  5. Eco-Anthropic Compatibility - a Multidisciplinary Model in Urban Ecology

    Directory of Open Access Journals (Sweden)

    MARIANO L. BIANCA

    2010-01-01

    Full Text Available In this paper I propose a multidisciplinary model of urban development which goes beyond the notion of ecological sustainability, by building on the concept of eco-anthropic compatibility. First of all I will sketch the historical development of human aggregations and I will underline the difference between ancient and modern aggregations. On the basis of this analysis, I will take into consideration the notion of sustainability and its possible application to present conurbations. I will underline several limits of the notion of sustainable development and I will propose a multidisciplinary model grounded on a broader and new notion: the eco-anthropic compatibility. Using this notion, which includes the idea of sustainability, it is possible to handle, within the model, the human factors and human living conditions inside an urban aggregation. Finally, I will state that the actual urban model is decaying and therefore, sooner or later, we will have to face the end of urban civilization; for this reason we can start imagining new future ways for human aggregations on the planet based on the notion of eco-anthropic compatibility.

  11. Types for BioAmbients

    Directory of Open Access Journals (Sweden)

    Sara Capecchi

    2010-02-01

    Full Text Available The BioAmbients calculus is a process algebra suitable for representing compartmentalization, molecular localization and movements between compartments. In this paper we enrich this calculus with a static type system classifying each ambient with group types specifying the kind of compartments in which the ambient can stay. The type system ensures that, in a well-typed process, ambients cannot be nested in a way that violates the type hierarchy. Exploiting the information given by the group types, we also extend the operational semantics of BioAmbients with rules signalling errors that may derive from undesired ambients' moves (i.e. merging incompatible tissues. Thus, the signal of errors can help the modeller to detect and locate unwanted situations that may arise in a biological system, and give practical hints on how to avoid the undesired behaviour.

    A sustainable bio fuels production cannot ignore the competition between the food and agroenergy chains for the cultivable land, and many advocate oleaginous microbial biomass as a possible solution to this problem. Their advantages include fast growth, significant oil content, productivity significantly larger than that featured by higher plants but, most importantly, the possibility of exploiting marginal lands. Before they can be deployed on a large scale, some remaining critical points must be solved

    2015-12-01

    Full Text Available Following the trend on focusing on a nation’s economic-growth, side effects such as resource exhaustion, environmental pollution, and social injustice have begun to appear. As a solution, eco-innovation has received a great amount of attention from European countries and as a result, many efforts to analyze the development of eco-innovation quantitatively have been made. This study aims to evaluate the validity of an eco-innovation index developed to support the sustainable development goal. For this purpose, four factors of eco-innovation—capacity, supportive environment, activity, and performance—were applied to three categories of the Triple-Bottom-Line (TBL concept in sustainability to compare the eco-innovation development level of 49 Asia-Europe Meeting countries. Factors for eco-innovation and TBL at the country level were organized in quartile and compared to see strength and weaknesses for each nation. In order to test if eco-innovation factors of a nation adequately reflect its sustainability, we used various comparisons of ANOVA. The results of this study are as follows: First, the one-way ANOVA tests present the scores for capacity, supportive environment, and performance as grouped into four quartiles in the same pattern as their economic, social, and environmental scores. The three-way ANOVA tests showed significance for the economic category. Scores for capacity, supportive environment, activity and performance were significant at a nation’s economic level. Lastly, the MANOVA test revealed that TBL significantly explains four eco-innovation factors. In addition, the eco-innovation performance level of European nations and Asian nations were compared. The possibility that many nations still have room to be competitive in their eco-innovation efforts was identified. Nations with unbalanced eco-innovation growth are urged to implement new strategies to balance their growth. Therefore, this research contributes to extending

    2011-01-01

    Bio fertilizers contain live beneficial microorganisms that provide nutrients and other benefits to crops. At present, bio fertilizers can be found in solid and liquid forms. Liquid bio fertilizer can be one of the alternatives to chemical fertilizers and pesticides. Liquid bio fertilizer is produced through culturing of microorganisms that are known to have specific capabilities in helping plant growth. However, application of bio fertilizers in the form of solution is more tedious than that of solid bio fertilizers, which can be applied directly to plants, whereas the liquid form requires several stages of preparation before it can be applied to crops. In Malaysian Nuclear Agency, a study on the distribution of liquid bio fertilizers to crops through the fertigation system has been conducted. In Malaysia, this study has not been conducted in depth, since the present fertigation system is associated to delivery of solubilised mineral fertilizers. This paper discusses the application of liquid bio fertilizers through a fertigation system. Discussions cover technical aspects of bio fertilizer preparation and its application via the said system. Tomato plant was used as test crop to determine the capability and efficiency of bio fertilizer application through the fertigation system. (author)

    2015-01-01

    Waste cooking oil (WCO) was chemically modified via epoxidation using H2O2 followed by transesterification with methanol and branched alcohols (isooctanol, isotridecanol and isooctadecanol) to produce bio-lubricants with improved oxidative stability and low temperature properties. Physicochemical properties of synthesized bio-lubricants such as pour point (PP), cloud point (CP), viscosity, viscosity index (VI), oxidative stability, and corrosion resistant property were determined according to standard methods. The synthesized bio-lubricants showed improved low temperature flow performances compared with WCO, which can be attributing to the introduction of branched chains in their molecular structures. What's more, the oxidation stability of the WCO showed more than 10 folds improvement due to the elimination of -C=C-bonds in the WCO molecule. Tribological performances of these bio-lubricants were also investigated using four-ball friction and wear tester. Experimental results showed that derivatives of WCO exhibited favorable physicochemical properties and tribological performances which making them good candidates in formulating eco-friendly lubricants.

    Regional eco-environmental quality is the key and foundation to the sustainable socio-economic development of a region. Eco-environmental quality assessment can reveal the capacity of sustainable socio-economic development in a region and the degree of coordination between social production and the living environment. As part of a new development strategy for Fujian Province, the Western Taiwan Straits Economic Zone (hereafter referred to as the Economic Zone) provides an important guarantee for the development of China's southeastern coastal area. Based on ecological and remote sensing data on the Economic Zone obtained in 2000, 2005, and 2010, this study investigated county-level administrative regions with a comprehensive index of eco-environmental indicators. An objective weighting method was used to determine the importance of each indicator. This led to the development of an indicator system to assess the eco-environmental quality of the economic zone. ArcGIS software was used to assess the eco-environmental quality of the economic zone based on each indicator. The eco-environmental quality index (EQI) of the county-level administrative regions was calculated. The overall eco-environmental quality of the Economic Zone during the period studied is described and analyzed. The results show that the overall eco-environmental quality of the Economic Zone is satisfactory, but significant intraregional differences still exist. The key to improving the overall eco-environmental quality of this area is to restore vegetation and preserve biodiversity.

    Eco-design is crucial to take environmental aspects into account in the phases of design. Few literature review that green product must meet market value. The development of models to predict market value is thus very useful because it can provide early eco-efficiency to the eco-design. For the eco-design engineer, when he tries to solve a customer feedback problem, he usually faces the eco-efficiency. There are, however, often other types of fuzziness uncertainty present, which are related to the quantity of eco-design conditions. In this paper, it is derived that analysis of eco-efficiency can be identified by using the RFM value for quantifying eco-design with Takagi-Sugeno fuzzy system on customer feedback problem. It clusters eco-efficiency into segments according to green product usages value expressed in terms of weighted RFM. This experiment examined the weighted RFM effect of overall average normalized, AHP and non-weighted for F1 metric. The experimental results show that the proposed methodology indeed can yield identification of higher quality

    Generation of wastewater is one of the main environmental sustainability issues across food sector industries. The constituents of food process effluents are often complex and require high energy and processing for regulatory compliance. Wastewater streams are the subject of microbiological and chemical criteria, and can have a significant eco-toxicological impact on the aquatic life. Thus, innovative treatment approaches are required to mitigate environmental impact in an energy efficient manner. Here, dielectric barrier discharge atmospheric cold plasma (ACP) was evaluated for control of key microbial indicators encountered in food industry effluent. This study also investigated the eco-toxicological impact of cold plasma treatment of the effluents using a range of aquatic bioassays. Continuous ACP treatment was applied to synthetic dairy and meat effluents. Microbial inactivation showed treatment time dependence with significant reduction in microbial populations within 120 s, and to undetectable levels after 300 s. Post treatment retention time emerged as critical control parameter which promoted ACP bacterial inactivation efficiency. Moreover, ACP treatment for 20 min achieved significant reduction (≥2 Log 10 ) in Bacillus megaterium endospores in wastewater effluent. Acute aquatic toxicity was assessed using two fish cell lines (PLHC-1 and RTG-2) and a crustacean model (Daphnia magna). Untreated effluents were toxic to the aquatic models, however, plasma treatment limited the toxic effects. Differing sensitivities were observed to ACP treated effluents across the different test bio-assays in the following order: PLHC-1 > RTG-2 ≥ D. magna; with greater sensitivity retained to plasma treated meat effluent than dairy effluent. The toxic effects were dependent on concentration and treatment time of the ACP treated effluent; with 30% cytotoxicity in D. magna and fish cells observed after 24 h of exposure to ACP treated effluent for

  12. Sustainable Capital? The Neoliberalization of Nature and Knowledge in the European “Knowledge-based Bio-economy”

    2010-09-01

    Full Text Available As an EU policy agenda, the “knowledge-based bio-economy” (KBBE emphasizes bio-technoscience as the means to reconcile environmental and economic sustainability. This frames the sustainability problem as an inefficiency to be overcome through a techno-knowledge fix. Here ecological sustainability means a benign eco-efficient productivity using resources which are renewable, reproducible and therefore sustainable. The KBBE narrative has been elaborated by European Technology Platforms in the agri-food-forestry-biofuels sectors, whose proposals shape research priorities. These inform policy agendas for the neoliberalization of both nature and knowledge, especially through intellectual property. In these ways, the KBBE can be understood as a new political-economic strategy for sustainable capital. This strategy invests great expectations for unlocking the productive potential of natural resources through a techno-knowledge fix. Although eco-efficiency is sometimes equated with biological productivity, commercial success will be dependent upon new combinations of “living” and “dead” labour.

  13. Feedback-Based Eco-Design for Integrating the Recency, Frequency, and Monetary Value of Eco-Efficiency into Sustainability Management

    2016-09-01

    Full Text Available Customer feedback is used to understand customer requirements. Early design phases require the consideration of items including manufacturing, the environment, and sustainability management. Therefore, it is crucial that eco-efficiency is taken into account in the early design phases. Traditionally, eco-efficiency is considered only in terms of eco-design issues, not customer requirements based on business values such as Recency, Frequency, and Monetary (RFM value. In the meantime, integrating innovation from eco-design is one important aspect. Here, I propose that customer feedback-based eco-efficiency and TRIZ-based innovation can be considered in early eco-design based on the RFM value for sustainability management. The analytic hierarchy process (AHP and fuzzy-based AHP were integrated to explore the relative weights of RFM variables for business value evaluation. The innovative method of the paper is using a TRIZ contradiction matrix associated with engineering parameters for eco-design. The experimental study has been carried out, and it meets the forecasting business value for green product usage. The business value was used as the decision-making factor in order to evaluate both environmental and marketing performance.

    This study examined bio-oil and bio-char fuel produced from Spirulina Sp. by slow pyrolysis. A thermogravimetric analyser (TGA) was used to investigate the pyrolytic characteristics and essential components of algae. It was found that the temperature for the maximum degradation, 322 °C, is lower than that of other biomass. With our fixed-bed reactor, 125 g of dried Spirulina Sp. algae was fed under a nitrogen atmosphere until the temperature reached a set temperature between 450 and 600 °C. It was found that the suitable temperature to obtain bio-char and bio-oil were at approximately 500 and 550 °C respectively. The bio-oil components were identified by a gas chromatography/mass spectrometry (GC–MS). The saturated functional carbon of the bio-oil was in a range of heavy naphtha, kerosene and diesel oil. The energy consumption ratio (ECR) of bio-oil and bio-char was calculated, and the net energy output was positive. The ECR had an average value of 0.49. -- Highlights: •Bio-oil and bio-char fuel produced from Spirulina Sp. by slow pyrolysis. •Suitable temperature to obtained bio-oil and bio-char were at about 550 and 500 °C. •Saturated functional carbon of bio-oil was heavy naphtha, kerosene, diesel oil. •ECR had an average value of 0.49

    Full Text Available BACKGROUND: Chagas disease is a vector-borne disease of major importance in the Americas. Disease prevention is mostly limited to vector control. Integrated interventions targeting ecological, biological and social determinants of vector-borne diseases are increasingly used for improved control. METHODOLOGY/PRINCIPAL FINDINGS: We investigated key factors associated with transient house infestation by T. dimidiata in rural villages in Yucatan, Mexico, using a mixed modeling approach based on initial null-hypothesis testing followed by multimodel inference and averaging on data from 308 houses from three villages. We found that the presence of dogs, chickens and potential refuges, such as rock piles, in the peridomicile as well as the proximity of houses to vegetation at the periphery of the village and to public light sources are major risk factors for infestation. These factors explain most of the intra-village variations in infestation. CONCLUSIONS/SIGNIFICANCE: These results underline a process of infestation distinct from that of domiciliated triatomines and may be used for risk stratification of houses for both vector surveillance and control. Combined integrated vector interventions, informed by an Ecohealth perspective, should aim at targeting several of these factors to effectively reduce infestation and provide sustainable vector control.

    In this study, we have described three steps to produce ethanol from Pogonatherum crinitum , which was derived after the treatment of textile wastewater. (a) Production of biomass: biomass samples collected from a hydroponic P. crinitum phytoreactor treating dye textile effluents and augmented with Ca-alginate immobilized growth-promoting bacterium, Bacillus pumilus strain PgJ (consortium phytoreactor), and waste sorghum husks were collected and dried. Compositional analysis of biomass (consortium phytoreactor) showed that the concentration of cellulose, hemicelluloses and lignin was 42, 30 and 17%, respectively, whereas the biomass samples without the growth-promoting bacterium (normal phytoreactor) was slightly lower, 40, 29 and 16%, respectively. (b) Hydrolysate (sugar) production: a crude sample of the fungus, Phanerochaete chrysosporium containing hydrolytic enzymes such as endoglucanase (53.25 U/ml), exoglucanase (8.38 U/ml), glucoamylase (115.04 U/ml), xylanase (83.88 U/ml), LiP (0.972 U/ml) and MnP (0.459 U/ml) was obtained, and added to consortium, normal and control phytoreactor derived biomass supplemented with Tween-20 (0.2% v/v). The hydrolysate of biomass from consortium phytoreactor produced maximum reducing sugar (0.93 g/l) than hydrolysates of normal phytoreactor biomass (0.82 g/l) and control phytoreactor biomass (0.79 g/l). FTIR and XRD analysis confirmed structural changes in treated biomass. (c) Ethanol production: the bioethanol produced from enzymatic hydrolysates of waste biomass of consortium and normal phytoreactor using Saccharomyces cerevisiae (KCTC 7296) was 42.2 and 39.4 g/l, respectively, while control phytoreactor biomass hydrolysate showed only 25.5 g/l. Thus, the amalgamation of phytoremediation and bioethanol production can be the truly environment-friendly way to eliminate the problem of textile dye along with bioenergy generation.

  17. A case against bio markers as they are currently used in radioecological risk analyses: a problem of linkage

    2005-01-01

    Bio-markers are successfully used in human risk analyses as early indicators of contaminant exposure and predictors of deleterious effects. This has boosted the search for bio-markers in determining ecological risks to non-human biota, and particularly for assessments related to radioactive contaminants. There are difficulties, however, that prevent an easy transfer of the bio-marker concept from humans to non-human biota, as there are significant differences in endpoints of concern, units of observation and dose response relationships between human and ecological risk analyses. The use of bio-markers in ecological risk analyses currently lacks a linkage between molecular-level effects and quantifiable impacts observed in individuals and populations. This is important because ecological risk analyses generally target the population level of biological organisation. We highlight various examples that demonstrate the difficulties of linking individual responses to population-level impacts, such as indirect effects and compensatory interactions. Eco-toxicologists cope with such difficulties through the use of uncertainty or extrapolation factors. Extrapolation factors (EF) typically range from 1 to 1000 when linking effects observed in individuals to those predicted to occur in populations. We question what magnitude of EF will be required when going from a molecular level effect, measured by a bio-marker, all the way up to the population level of biological organisation. Particularly, we stress that a successful application of bio-markers to radioecological risk assessment can only be achieved once the connection has been made between changes in individual resource allocation-based life histories and population dynamics. This clearly emphasises the need to quantify the propagation of molecular and cellular level effects to higher levels of biological organisation, especially in the long-term via several generations of exposure. Finally, we identify pertinent research

    Pro-Cool is an EU-wide demonstration project which supports the development and market penetration of eco-efficient plug-in cold appliances for the commercial use. These products should be both highly energy efficient, free of HFC-containing refrigerants and -foaming agents and eco-efficient in a general sense. Thus the project corresponds with the EU Integrated Product Policy which aims at improving products by considering the ecological impact along the product life cycle. Besides ecological criteria, which are central for the project, other aspects relevant for purchasers like warranty and functionality are taken into account to guarantee the acceptance of the products by the demand side target groups. The so called 'voice of the customer' has been considered in the development of the criteria To achieve the necessary stimulation of the supply and demand side market a combined competition and procurement approach is developed addressing both manufacturers and buyers respectively users of the products. The central measure of the project is a European competition for suppliers what offers leading manufacturers of the market the opportunity to present themselves as innovative companies which provide eco-efficient equipment. Eight leading manufacturers which have a high market share in the selected product categories are taking part in the competition. Furthermore three large companies representing the demand side branches of super market chains and drinks industry already have signed a general agreement to support the project and to consider the products resulting from the competition in their procurement activities. Thus major supply and demand side target groups which are capable to support market transformation have joined the project. The competition terminates by December 2005 and the award of the winning products takes place in spring 2006 at an international fair or conference event. The paper presents the objectives and the concept of the project. Relevant

    Oceanographic data collected in the Arctic are valuable in view of the role of this region in the studies on global climate change and the fact that historically the number of in situ measurements is relatively low. Porsangerfjorden, Norway, is an example of oceanic basin with case 2 water according to the optical classification. Optical data from coastal seas are difficult in interpretation because the concentrations of optically important components can be high, variable, and not covarying with each other. Porsanger Fjord can be divided into three basins: inner, middle and outer, where physical and bio-optical properties of water masses differ. We collected optical data and water samples for phytoplankton pigments, dissolved organic matter, particulate (POC) and dissolved (DOC) organic carbon, and particulate inorganic carbon (PIC) during our two summer expeditions in 2014 and 2015. In this presentation we focus on data collected with WETLabs' ac-9 and ac-s spectrophotometers and ECO-Triplet and ECO-Triplet-w fluorometers. Concurrently with in situ optical measurements water samples were collected in situ and soon afterwards they were filtered in the laboratory at the station, stored and transported for further processing in Poland. Our analysis includes 146 of in situ measurements and discrete water samples: 62 of POC, 52 of PIC, 33 of DOC, 68 of dissolved organic matter and 89 of phytoplankton pigments. During our analysis we compare chlorophyll (Chl_a), dissolved organic matter (CDOM) and carbon concentrations with in situ collected inherent optical properties of sea water to find empirical proxies allowing to estimate various water component concentrations from optical data. Application of these proxies to available bio-optical data allowed us to derive spatial distribution of these water constituents and their variability.

    BioC is a simple XML format for text, annotations and relations, and was developed to achieve interoperability for biomedical text processing. Following the success of BioC in BioCreative IV, the BioCreative V BioC track addressed a collaborative task to build an assistant system for BioGRID curation. In this paper, we describe the framework of the collaborative BioC task and discuss our findings based on the user survey. This track consisted of eight subtasks including gene/protein/organism named entity recognition, protein-protein/genetic interaction passage identification and annotation visualization. Using BioC as their data-sharing and communication medium, nine teams, world-wide, participated and contributed either new methods or improvements of existing tools to address different subtasks of the BioC track. Results from different teams were shared in BioC and made available to other teams as they addressed different subtasks of the track. In the end, all submitted runs were merged using a machine learning classifier to produce an optimized output. The biocurator assistant system was evaluated by four BioGRID curators in terms of practical usability. The curators' feedback was overall positive and highlighted the user-friendly design and the convenient gene/protein curation tool based on text mining.Database URL: http://www.biocreative.org/tasks/biocreative-v/track-1-bioc/.

    The sensitivity of doses calculated by the generic biosphere code ECOS to parameter changes has been investigated by the authors for the Department of the Environment as part of its radioactive waste management research programme. The sensitivity of results to radionuclide dependent parameters has been tested by specifying reasonable parameter ranges and performing code runs for best estimate, upper-bound and lower-bound parameter values. The work indicates that doses are most sensitive to scenario parameters: geosphere input fractions, area of contaminated land, land use and diet, flux of contaminated waters and water use. Recommendations are made based on the results of sensitivity. (author)

    Traditionally, the transportation industry has been opposed to any new legislation and when rather stringent emission legislation occurred, they objected just as they did when new fuels came on the agenda. On very short notice, Taxi Stockholm lost 20 % of their business when the County decided to award all public transportation contracts to a competitor. It was time to change plans instead of complaining and to take advantage of new opportunities - 'The first mover advantage'. Making the use of bio fuels into a profitable business takes a change of a standard 'business model' to do and there is still much room others to do the same. With a new CEO, an active marketing department and active individuals among the Board of Directors, Taxi Stockholm massaged a strategy where more business and private customers would be attracted by justifying the green leaf on every cab. All initiatives were publically announced and Taxi Stockholm broke new ice by putting a ban on spike tires - a decision which the vice Mayor made part of her ruling for the whole city. The Ban on gasoline and diesel cars were announced and such a statement attracted business from a loyalty point of view and from companies that had a 'Green Transport Policy' to live up to. Taxi Stockholm has seen growth and profitability grow since and credit the green policy on bio fuels such as bio gas and ethanol for most of it. Preem, Stockholm Transit, Volvo and other market driven operators have all seen markets grow from green initiatives.

    2017-07-01

    Full Text Available With the increasing awareness of sustainability, eco-design has been an important trend in the fashion industry. Many fashion brands such as Nike, Adidas, and The North Face have developed sustainable fashion by incorporating eco-design elements. Eco-design is an important part of sustainable supply chains. In this paper, we conducted a product line analysis of eco-designed products from a famous outdoor sportswear brand, Patagonia. We collected Patagonia’s 2017 Spring Season product line data and analyzed the data through descriptive analysis, factor analysis and correlation analysis. We found that Patagonia mainly uses organic, recycled, and traceable materials in their eco-product line development. We identified that the usage of eco-materials may significantly affect the number of color choices and product weight as well as gender difference, pattern design, product fit and online reviewers’ opinions at Patagonia. We argued that Patagonia should focus on functionality more than aesthetics in eco-design. We discussed how sustainable fashion firms should manage eco-design in the supply chain.

    This paper first applied material flow analysis (MFA) to construct three levels of regional eco-efficiency indicators, i.e., regional direct eco-efficiency (RDE), regional total eco-efficiency (RTE), and holistic eco-efficiency (HE), and adopted the newly developed data envelopment analysis (DEA) to evaluate the eco-efficiency of Tongling City during the period of 1990-2008. We also applied Malmquist productivity index (MPI) to explore the eco-efficiency change between two following years and its driving factors. The main results were summarized as 1) though the RDE of Tongling City in 1990-2008 kept an increasing trend, its mean eco-efficiency was not high (close to 0.8 in 80% of the years), being lower than that of the RTE and HE, and 2) the RDE change was closely relevant to the improvement in resource management and the technical input in environmental protection in recent years. In order to further improve the RDE of the City, it would be necessary to raise its eco-efficiency via expanding raw material input, reducing domestic extraction, promoting resources productivity, and taking more measures on environmental protection facilities construction.

    Heavy-metal-polluted biomass derived from phytoremediation or biosorption is widespread and difficult to be disposed of. In this work, simultaneous conversion of the waste woody biomass into bio-oil and recovery of Cu in a fast pyrolysis reactor were investigated. The results show that Cu can effectively catalyze the thermo-decomposition of biomass. Both the yield and high heating value (HHV) of the Cu-polluted fir sawdust biomass (Cu-FSD) derived bio-oil are significantly improved compared with those of the fir sawdust (FSD) derived bio-oil. The results of UV-vis and (1)H NMR spectra of bio-oil indicate pyrolytic lignin is further decomposed into small-molecular aromatic compounds by the catalysis of Cu, which is in agreement with the GC-MS results that the fractions of C7-C10 compounds in the bio-oil significantly increase. Inductively coupled plasma-atomic emission spectrometry, X-ray diffraction, and X-ray photoelectron spectroscopy analyses of the migration and transformation of Cu in the fast pyrolysis process show that more than 91% of the total Cu in the Cu-FSD is enriched in the char in the form of zerovalent Cu with a face-centered cubic crystalline phase. This study gives insight into catalytic fast pyrolysis of heavy metals, and demonstrates the technical feasibility of an eco-friendly process for disposal of heavy-metal-polluted biomass.

    Global environment handling technologies were investigated and put into order. Universities often make research and development on themes that can be handled at laboratory levels or by simulations. Development at a practical application level is few. Technological seeds may include manufacture of hydrogen by water and steam decomposition using solar energy, and new synthesizing reactions utilizing solar energy. Included may also be urban type wind power generation, superconductive energy storage systems, biomass utilization, and natural energy utilization. Furthermore, CO2 recovery and utilization by liquefaction, alkaline metal heat power generation, and pulse power technologies can also be found. Studies on applying advanced technologies to environmental measures include composite materials, membrane separation, photo-catalysts, optical elements, porous bodies, functional polymers, bio-reactors, electron beams, and aeration. Private corporations are working noticeably on prevention of fluorocarbon and dioxin emission, PCB treatment and waste water treatment technologies, catalyst application technologies, recycling technologies, and incineration ash treatment and utilization technologies.

    2018-04-01

    Full Text Available Concerns about climate change have forced countries to strengthen regulations, standards, and certifications related to greenhouse gas emissions. Various policies targeting farm products, such as carbon labeling and the Environmentally-Friendly Agricultural Product Certification (EFAPC for agricultural products, have been implemented in South Korea to reduce greenhouse gas emissions in the agricultural sector. The purpose of this study was to evaluate the implications of the various certification systems for rice farming, including organic farming, non-pesticide farming, and low-pesticide farming. For this study, we constructed a life cycle inventory (LCI of rice farming systems including conventional, low-pesticide, non-pesticide, and organic farming systems in South Korea. Finally, we compared international farming systems in South Korea, the U.S., and the EU. The rice farming systems with eco-labeling certifications have reduced the environmental impacts. The environmental impacts of rice farming by country were highest in the U.S. (100.0, followed by the EU (53.7, and Korea’s conventional (48.6, low-pesticide (35.8, non-pesticide (28.9, and organic (16.7 farming practices. These results may be useful in proliferating and improving the methodology to evaluate eco-labeling and carbon labeling systems.

    Full Text Available Through the Economic Transformation program the Malaysian Government aims to consider tourism as one of the major contributors to the country’s economy and as an industry that imbibe on the principles of environmental responsibility and sustainable development. The growing challenges in the prevention of expansion in agriculture, forestry and aquaculture, and over-exploitation of the natural resources, have made ecotourism extremely popular as a solution for developing tourism sites. Ecotourism attracts many people who wish not only to explore natural wonders but also to protect them for future generations. Most of the ecotourism sites are presumably situated far from the conventional energy resources and thus transporting electricity to those areas are discussed as inefficient and unsustainable. However, solar Photo-voltaic (PV system is clean and alternative energy to suffice the energy demands of eco-tourist sites. This paper puts statements of the energy demand in global and its impact on the traditional fossil fuels and proposes PV as an alternative renewable technology pertaining to the eco-tourism application. The paper especially focuses on solar PV systems which not only could supply the energy demand of tourist sites but can also maintain the image of the ecotourism. A case of a model lodge is used for the study, through the energy demand analysis. A comprehensive review on the PV architecture is presented that derive interest in the implementation of such structure for the case presented.

    2017-11-01

    Fly ash (FA) and Alccofine are the eco-friendly materials that can be used in the production of concrete composites. Initially, concrete mixes of M30 grade with replacement of cement by 0%, 5%, 10%, 15%, 20% and 25% by weight of Fly ash were prepared. They were subjected to compression test so as to select the optimum replacement percentage of FA. Keeping this optimum percentage of FA as constant, additional replacement of cement with Alccofine was done varying its replacement in the range of 8%, 10%, 12% and 14%. The mechanical properties such as compressive, split tensile and flexural strengths of these mixes were computed for 7, 14 and 28 days. The results of Eco-Friendly Concrete (EFC) are compared with those of control concrete. It was observed that EFC mixes exhibited superior qualities like quick setting and enhanced workability, their mechanical properties were found to be higher than that of the conventional concrete. This goes to prove that the combination of FA and Alccofine together as replacement for cement would enhance the properties of EFC.

    2018-03-01

    Full Text Available Ecocities can provide solutions for the improvement of human settlements around the world and the living conditions therein, but in the authors’ experience, only as long as they are able to address the following questions correctly: How to formulate an ecocity concept that, considering issues of general concern, can be at the same time adapted to different local conditions? What are the instruments supporting the development and implementation of ecocity solutions? VTT’s EcoCity concept for sustainable community and neighbourhood regeneration and development has been designed in response to the first question. Likewise, specific methodologies and effective facilitation processes and skills have been developed in response to the second question. Since the methodologies have been discussed in a previous scientific article, the present one focuses on the facilitation processes and skills, and also on other related, fundamental aspects like participation, adaptation, capacity building, etc. Facilitation processes supporting EcoCity development require matching “hard” and “soft” skills in a fluid way. The main findings are discussed with the help of two case studies: one in Medellín (Colombia, and the other one in Zambia.

    2015-07-01

    Full Text Available This paper discusses vegetarian eco-feminist consciousness in Carol Ann Duffy’s poetry by close analysis of two poems, namely “The Dolphins” and “A Healthy Diet” from her poem collection Standing Female Nude. The former is a dramatic monologue of a dolphin, which is exploited by people, and the latter is a dramatic monologue of an omnipotent observer in a restaurant. Both poems criticized the species-ism, and together, they showed the poet’s vegetarian eco-feminist consciousness. A close reading of the two poems from the eco-feminist perspective helps the reader understand why Carol Ann Duffy is honored as the first woman poet laureate in British history, and better understand vegetarian eco-feminism and its influence in British society.

Based on a 200-million GPS record data set collected from 150 vehicles in Denmark over two years, a comprehensive empirical study is conducted...... transportation. The foundation of eco-routing is a weighted-graph representation of a road network in which road segments, or edges, are associated with eco-weights that capture the GHG emissions caused by traversing the edges. Due to the dynamics of traffic, the eco-weights are best modeled as being time...... dependent and uncertain. We formalize the problem of assigning a time-dependent, uncertain eco-weight to each edge in a road network based on historical GPS records. In particular, a sequence of histograms is employed to describe the uncertain eco-weight of an edge at different time intervals. Compression...

    The knowledge of the space/time variations of species is the basis for any ecological investigations. While historical observations containing integral concentrations of biological parameters (chlorophyll, abundance, biomass…) are organized partly in ISRAMAR Cast Database, the taxon-specific data collected in Israel has not been sufficiently organized. This has been hindered by the lack of standards, variability of methods and complexity of biological data formalization. The ISRAMAR-BIO DB was developed to store various types of historical and future available information related to marine species observations and related metadata. Currently the DB allows to store biological data acquired by the following sampling devices such as: van veer grab, box corer, sampling bottles, nets (plankton, trawls and fish), quadrates, and cameras. The DB's logical unit is information regarding a specimen (taxa name, barcode, image), related attributes (abundance, size, age, contaminants…), habitat description, sampling device and method, time and space of sampling, responsible organization and scientist, source of information (cruise, project and publication). The following standardization of specimen and attributes naming were implemented: Taxonomy according to World Register of Marine Species (WoRMS: http://www.marinespecies.org). Habitat description according to Coastal and Marine Ecological Classification Standards (CMECS: http://www.cmecscatalog.org) Parameter name; Unit; Device name; Developmental stage; Institution name; Country name; Marine region according to SeaDataNet Vocabularies (http://www.seadatanet.org/Standards-Software/Common-Vocabularies). This system supports two types of data submission procedures, which support the above stated data structure. The first is a downloadable excel file with drop-down fields based on the ISRAMAR-BIO vocabularies. The file is filled and uploaded online by the data contributor.

    The paper is based on the ESTO Study: Techno- Economic Feasibility of Large-Scale Production of Bio-Fuels in EU-Candidate Countries. Bio-fuel production has not been taken into account significantly until now in Romania, being limited to small- scale productions of ethanol, used mostly for various industrial purposes. However the climatic conditions and the quality of the soil are very suitable in the country for development of the main crops (wheat, sugar-beet, sunflower and rape-seed) used in bio-ethanol and bio-diesel production. The paper intended to consider a pertinent discussion of the present situation in Romania's agriculture stressing on the following essential items in the estimation of bio-fuels production potential: availability of feed-stock for bio-fuel production; actual productions of bio-fuels; fuel consumption; cost assessment; SWOT approach; expected trends. Our analysis was based on specific agricultural data for the period 1996-2000. An important ethanol potential (due to wheat, sugar-beet and maize cultures), as well as bio-diesel one (due to sun-flower and rape-seed) were predicted for the period 2005-2010 which could be exploited with the support of an important financial and technological effort, mainly from EU countries

    2016-04-01

    Full Text Available The present study was created in order to customise the marketing mix for non-purchasers of eco-friendly products by studying their perspectives on the introduction of eco-friendly variants of the regular products that they are using in particular product categories (personal care and home care. Overall previous literature reviews in this area imply that there is a gap in the scientific literature on the marketing mix formulation for converting non-purchasers into purchasers of eco-friendly products to augment eco-friendly product sales and adopt green marketing. As literature reviews had clearly indicated that green purchasers have a very low percentage when compared to non-purchasers, the purpose is to create new opportunities for successful green marketing as the study tries to convert non-purchasers into purchasers. We used descriptive research design to study a sample of 885 respondents, who were surveyed in 2 cities in the Tamil Nadu state in India, to acquire an in-depth understanding of consumer behaviour that would enable the consumption of eco-friendly products among non-purchasers. The results reveal the marketing mix requirement and the eco-friendly aspects needed by the non-purchasers in order to buy the eco-friendly variants. The research sheds light on the product, price and promotion components that will attract non-purchases of eco-friendly products to buy eco-friendly products, thus facilitating green marketing mix adaptation. The study will provide valuable input for further research in formulating the marketing mix necessary to enable consumption of eco-friendly products in different geographical locations and various product categories.

    Land use/land cover change has been attracting increasing attention in the field of global environmental change research because of its role in the social and ecological environment. To explore the ecological risk characteristics of land use change in the Poyang Lake Eco-economic Zone of China, an eco-risk index was established in this study by the combination of a landscape disturbance index with a landscape fragmentation index. Spatial distribution and gradient difference of land use eco-risk are analyzed by using the methods of spatial autocorrelation and semivariance. Results show that ecological risk in the study area has a positive correlation, and there is a decreasing trend with the increase of grain size both in 1995 and 2005. Because the area of high eco-risk value increased from 1995 to 2005, eco-environment quality declined slightly in the study area. There are distinct spatial changes in the concentrated areas with high land use eco-risk values from 1995 to 2005. The step length of spatial separation of land use eco-risk is comparatively long—58 km in 1995 and 11 km in 2005—respectively. There are still nonstructural factors affecting the quality of the regional ecological environment at some small-scales. Our research results can provide some useful information for land eco-management, eco-environmental harnessing and restoration. In the future, some measures should be put forward in the regions with high eco-risk value, which include strengthening land use management, avoiding unreasonable types of land use and reducing the degree of fragmentation and separation.

    During COP21, Schneider Electric has committed that 100% of our new products would be eco-designed to tackle climate change. Launched in 2015, this initiative ecoDesign WayTM was tested on some pilot projects. This project covers the first ecoDesign WayTM pilot in China on an overvoltage or under voltage protective device used in both residential and industrial sectors, called Monsoon. Under the name ecoDesign WayTM, a method and a process have been deployed. The 3 main ecoDesign WayTM phases are: phase 1 - Marketing & Technique handshake, Phase 2 - ecoDesign WayTM follow-up and Phase 3 - Marketing communication. During the project, EIME from Bureau Veritas CODDE and ecoDesign WayTM scorecard from EVEA consulting are two core tools for eco-design implementation. They are respectively used for life cycle assessment and eco-design performance comparison. Thanks to the approach, compared to previous range, pollution emissions and resource depletion along the whole life cycle of product have decreased (reduction of 55% for energy depletion and 85% for water depletion). Global warming potential has dramatically decreased by 98.4% and air pollution by 33%. Meanwhile, the recycling rate has been improved by 18%, and recycled PA is used. The ecoDesign WayTM scorecard is stored as referent document for any customer request. Moreover, customers can access RoHS certificate, REACh declaration, PEP and EoLI in Check a product, an online environmental data repository, available 24/7.

    2014-04-01

    Full Text Available Many of the challenges associated with sustainable development can be traced in the way modern society produces and consumes. Production, distribution and supply of goods and services require material and energy consumption, having an impact on natural resources both quantitatively and qualitatively, generating waste, pollution and disrupting ecosystems. Ecobusiness intelligence is the capacity of people, processes and applications / tools to organize business information, to facilitate consistent access to them and analyse them in order to improve management decisions, for better performance management of the organizations that are increasingly pressed to synchronize their processes and services with a sustainable development agenda, through the development, testing and implementation of decision support software. By adopting sustainable practices, eco – intelligent companies can gain added value, increase market share and boost shareholder value. Moreover, the growing demand for "green" products has created new markets and the visionary entrepreneurs already reap the rewards of approaching sustainability. Large and small companies are learning that sustainable business practices not only help the environment but also can improve profitability by pursuing higher efficiency, fewer harmful side-effects, and better relationships with the community and more. Gaining competitive advantage is a core concern of the companies and the existence of systems of identification, extraction and analysis of available data in a company, but also from the external environment, to provide real support for business decisions, is an essential ingredient of success. This paper highlights the necessity of eco-intelligent tools that help determining the organization's strategies, identifying the perceptions and capabilities of the competitors, analyzing the effectiveness of current operations, deploying long-term prospects for environmental action and establishing

    2010-05-01

    Slopes affected by superficial sliding and subsequently re-stabilised with eco-engineering measures were investigated, particularly related to soil stability and plant diversity. The sites are situated in three different areas of beech-fir-spruce forest associations of the higher montane zone of Switzerland. Climatic and site characteristics, in paraticular soil properties after the sliding event, of the three investigation areas are very similar. However, the number of species (shrubs and trees) used for the initial planting as well as the year of application of the eco-engineering measures differ substantially. In the investigation area Dallenwil-Wirzweli the biological measures taken in 1981 were restricted to one tree species, namely White Alder (Alnus incana). In Klosters, where measures were taken in 1983 as well as in the Arieschbach valley, where eco-engineering was applied in 1998, the initial planting consisted of 15 species either. Investigations in 2005/2006 revealed neither obvious differences among the three areas nor distinct correlations related to the diversity of the initial planting on the on hand and the development of the vegetation cover and soil stability on the other hand. During the available time of development, the soil aggregate stability increased by 30 to 39%. Compared to the corresponding climax association, the relative values of soil aggregate stability varied between 90 and 120%. Concurrently, the dry unit weight decreased between 1.1 and 3.1 kN/m3. The cumulative vegetation cover varied from 110 to 150%. Due to processes of soil development a distinct shift in the grain size distribution was noticed, from a well sorted gravel with clay and sand (GW-GC) to a silty gravel with sand (GM) in Dallenwil-Wirzweli and a silty to clayey gravel with sand (GC-GM) in Klosters and the Arieschbach valley. Furthermore, in all three investigation areas succession processes were observed that are comparable to average rates of natural secondary

    Metal containing wastes/byproducts of various industries, used consumer goods, and municipal waste are potential pollutants, if not treated properly. They may also be important secondary resources if processed in eco-friendly manner for secured supply of contained metals/materials. Bio-extraction of metals from such resources with microbes such as bacteria, fungi and archaea is being increasingly explored to meet the twin objectives of resource recycling and pollution mitigation. This review focuses on the bio-processing of solid wastes/byproducts of metallurgical and manufacturing industries, chemical/petrochemical plants, electroplating and tanning units, besides sewage sludge and fly ash of municipal incinerators, electronic wastes (e-wastes/PCBs), used batteries, etc. An assessment has been made to quantify the wastes generated and its compositions, microbes used, metal leaching efficiency etc. Processing of certain effluents and wastewaters comprising of metals is also included in brief. Future directions of research are highlighted. Copyright © 2011 Elsevier Ltd. All rights reserved.

  19. Switchable bio-inspired adhesives

    Kroner, Elmar

    2015-03-01

    Geckos have astonishing climbing abilities. They can adhere to almost any surface and can run on walls and even stick to ceilings. The extraordinary adhesion performance is caused by a combination of a complex surface pattern on their toes and the biomechanics of its movement. These biological dry adhesives have been intensely investigated during recent years because of the unique combination of adhesive properties. They provide high adhesion, allow for easy detachment, can be removed residue-free, and have self-cleaning properties. Many aspects have been successfully mimicked, leading to artificial, bio-inspired, patterned dry adhesives, and were addressed and in some aspects they even outperform the adhesion capabilities of geckos. However, designing artificial patterned adhesion systems with switchable adhesion remains a big challenge; the gecko's adhesion system is based on a complex hierarchical surface structure and on advanced biomechanics, which are both difficult to mimic. In this paper, two approaches are presented to achieve switchable adhesion. The first approach is based on a patterned polydimethylsiloxane (PDMS) polymer, where adhesion can be switched on and off by applying a low and a high compressive preload. The switch in adhesion is caused by a reversible mechanical instability of the adhesive silicone structures. The second approach is based on a composite material consisting of a Nickel- Titanium (NiTi) shape memory alloy and a patterned adhesive PDMS layer. The NiTi alloy is trained to change its surface topography as a function of temperature, which results in a change of the contact area and of alignment of the adhesive pattern towards a substrate, leading to switchable adhesion. These examples show that the unique properties of bio-inspired adhesives can be greatly improved by new concepts such as mechanical instability or by the use of active materials which react to external stimuli.

  20. Development of an eco- and material-efficient pellet production chain. A chemical study

    2013-06-01

    According to the EU's strategy and the corresponding Finnish national strategy on waste materials, all kinds of waste must be utilised primarily as material (reuse, recycling) and secondarily as energy, and at the lowest level of waste hierarchy is their disposal using environmentally friendly methods. Today material efficiency is an essential topic in promoting sustainable use of natural resources, industrial by-products and waste material. The present goal proposed by the EU sets the target for the total proportion of renewable energy as high as 38% by 2020 in Finland. Up to 20 million tonnes of waste wood biomass per year are left unused in Finland, mainly in the forests during forestry operations, because supply and demand do not meet. As a consequence of high heat energy prices, the looming threat of climate change, the greenhouse effect and global as well as national demands to considerably increase the proportion of renewable energy, Finland currently has a tremendous interest in increasing decentralised pellet production alongside of large-scale factories. The aim of this thesis is to promote the development of eco-, material- and cost-efficient Nordic wood-based pellet production and utilisation of pellet bio-ash by means of chemical research. Using Finnish wood (sawdust and shavings) as a model raw material, the total functionality of a pilot-scale pellet facility combined with an extensive chemical toolbox was tested in this study to promote development of an eco-, material- and cost-efficient wood-based pellet production chain. The chemical toolbox includes measurements of moisture content, density, heat value, mechanical durability and particle size distribution, TG analysis and elementary analysis, as well as new applications for pellet biodegradation using BOD OxiTop equipment and optical microscopic staining methods. To improve the quality of pellets, considering the profitability of production and occupational safety factors (wood dust

    2015-11-01

    The purpose of this work is to study the adsorption process and surface bio-activity of His-tagged D-amino acid oxidase (DAAO) from Rhodotorula gracilis (His6-RgDAAO) as the first step for the development of an electrochemical bio-functionalized platform. With such a purpose this work comprises: (a) the His6-RgDAAO bio-activity in solution determined by amperometry, (b) the adsorption mechanism of His6-RgDAAO on bare gold and carboxylated modified substrates in the absence (substrate/COO-) and presence of Ni(II) (substrate/COO- + Ni(II)) determined by reflectometry, and (c) the bio-activity of the His6-RgDAAO bio-functionalized platforms determined by amperometry. Comparing the adsorption behavior and bio-activity of His6-RgDAAO on these different solid substrates allows understanding the contribution of the diverse interactions responsible for the platform performance. His6-RgDAAO enzymatic performance in solution is highly improved when compared to the previously used pig kidney (pk) DAAO. His6-RgDAAO exhibits an amperometrically detectable bio-activity at concentrations as low as those expected on a bio-functional platform; hence, it is a viable bio-recognition element of D-amino acids to be coupled to electrochemical platforms. Moreover, His6-RgDAAO bio-functionalized platforms exhibit a higher surface activity than pkDAAO physically adsorbed on gold. The platform built on Ni(II) modified substrates present enhanced bio-activity because the surface complexes histidine-Ni(II) provide with site-oriented, native-like enzymes. The adsorption mechanism responsible of the excellent performance of the bio-functionalized platform takes place in two steps involving electrostatic and bio-affinity interactions whose prevalence depends on the degree of surface coverage.

    Full Text Available Electrocorticography (ECoG has been demonstrated as a promising neural signal source for developing brain-machine interfaces (BMIs. However, many concerns about the disadvantages brought by large craniotomy for implanting the ECoG grid limit the clinical translation of ECoG-based BMIs. In this study, we collected clinical ECoG signals from the sensorimotor cortex of three epileptic participants when they performed hand gestures. The ECoG power spectrum in hybrid frequency bands was extracted to build a synchronous real-time BMI system. High decoding accuracy of the three gestures was achieved in both offline analysis (85.7%, 84.5%, and 69.7% and online tests (80% and 82%, tested on two participants only. We found that the decoding performance was maintained even with a subset of channels selected by a greedy algorithm. More importantly, these selected channels were mostly distributed along the central sulcus and clustered in the area of 3 interelectrode squares. Our findings of the reduced and clustered distribution of ECoG channels further supported the feasibility of clinically implementing the ECoG-based BMI system for the control of hand gestures.

    Designed especially for forest ecosystem studies, EcoSAR employs state-of-the-art digital beamforming technology to generate wide-swath, high-resolution imagery. EcoSARs dual antenna single-pass imaging capability eliminates temporal decorrelation from polarimetric and interferometric analysis, increasing the signal strength and simplifying models used to invert forest structure parameters. Antennae are physically separated by 25 meters providing single pass interferometry. In this mode the radar is most sensitive to topography. With 32 active transmit and receive channels, EcoSARs digital beamforming is an order of magnitude more versatile than the digital beamforming employed on the upcoming NISAR mission. EcoSARs long wavelength (P-band, 435 MHz, 69 cm) measurements can be used to simulate data products for ESAs future BIOMASS mission, allowing scientists to develop algorithms before the launch of the satellite. EcoSAR can also be deployed to collect much needed data where BIOMASS satellite wont be allowed to collect data (North America, Europe and Arctic), filling in the gaps to keep a watchful eye on the global carbon cycle. EcoSAR can play a vital role in monitoring, reporting and verification schemes of internationals programs such as UN-REDD (United Nations Reducing Emissions from Deforestation and Degradation) benefiting global society. EcoSAR was developed and flown with support from NASA Earth Sciences Technology Offices Instrument Incubator Program.

    2015-03-01

    Full Text Available Eco-environmental stress refers to the pressure borne by the environment in sustaining the pre-existing non-industrialized state and/or in counteracting adverse impacts caused by natural and human factors. The present article introduces the concept, research progress, and method for assessing eco-environmental stress. An eco-environmental stress index (ESI is established to assess the eco-environmental stress of 13 cities in the Western Taiwan Straits Economic Zone (hereafter referred to as the Economic Zone during the period from 2000 to 2010. The research provides a reference for the strategic planning of industrial development and environmental protection. The results show that the overall eco-environmental stress of the Economic Zone was slight and did not have significant change during the past 10 years. The cities with the most severe eco-environmental stress are distributed in the north and south of the Economic Zone. Most areas of Fujian Province have a low degree of eco-environmental stress, a situation that is being constantly improved. The regions with high atmospheric and water pollutant emissions are concentrated in the northern, middle, and southern coastal regions of the Economic Zone. The pollutant emissions of coastal cities are higher than those of inland cities. In the future, ecological restoration and compensation mechanisms should be established for regions where environmental protection and remediation is urgently needed.

  6. Synthesis of Constructs for Modeling Consumers’ Understanding and Perception of Eco-Labels

    2014-04-01

    Full Text Available The term “eco-labeling” has become a buzzword in today’s sustainable business world. The use of eco-labeling in various forms has been increasing notably for past many years, sometimes as an environmental “requirement” and sometimes merely as a marketing tool. Questions arise about how well these eco-labels are attended and understood by consumers. However, though mentionable studies are found on various aspects of eco-labels, gaps exist in exploring an inclusive set of parameters for investigating consumer perceptions of eco-labels. This paper aims at preparing a synthesis of all the possible factors to be incorporated for measuring consumer perceptions of eco-labeling of products. For making such synthesis, all major works in the field have been thoroughly reviewed. The paper comes up with a total of 10 parameters that include consumer awareness, consumer knowledge, consumer involvement, consumer trust, design and visibility, credibility of the source, type and level of information, clarity of meaning, persuasiveness, and private benefits. This tentative, yet inclusive, set of parameters is thought to be useful for designing large scale future empirical researches for developing a dependable inclusive set of parameters to test consumer understanding and perceptions of eco-label. A framework is proposed for further empirical research.

    Biomineralization is a natural process aided by living organisms. Due to its applicability in ground improvement and bioremediation, Microbially Induced Calcite Precipitation (MICP) is an interdisciplinary field of study combining engineering, chemistry and microbiology. Bioremediation has been applied widely for contamination containment or removal, in this case it will be containment. MICP can also be applied to improve the efficiency of insitu bioremediation. Urease is an enzyme which can facilitate increased calcite precipitation. However the production of urease by bacteria and thus the resulting carbonate precipitation are inhibited by environmental factors including calcium concentration, bacterial concentration, pH and temperature. Under good conditions MICP can be used for heavy metal and radionuclide immobilization. However technologies such as bioconsolidation and biocementation require improvement such as time and cost. This paper highlights the application of MICP in addition to suggested improvements to make it more eco-friendly and sustainable.

    Resource managers often face significant information technology (IT) problems when integrating ecological or environmental information to make decisions. At a workshop sponsored by the NSF and USGS in December 2004, university researchers, natural resource managers, and information managers met to articulate IT problems facing ecology and environmental decision makers. Decision making IT problems were identified in five areas: 1) policy, 2) data presentation, 3) data gaps, 4) tools, and 5) indicators. To alleviate those problems, workshop participants recommended specific informatics research in modeling and simulation, data quality, information integration and ontologies, and social and human aspects. This paper reports the workshop findings, and briefly compares these with research that traditionally falls under the emerging eco-informatics rubric. ?? Springer-Verlag Berlin Heidelberg 2005.

    Full Text Available Play therapy is a counseling approach for children applying toys, games, and other play media to communicate to the children "language." One of the Play therapy models that combine ecosystems as being formed by an inseparable reciprocal relationship between living things, and their environment is Eco systemic Play Therapy (EPT. Ecosystem Play Therapy as a hybrid model that integrates the concepts of science biology, several models of child psychotherapy, and developmental theories. This model is not eclectic. Rather, it is the integration of several models to create an independent model that is different from the sum of its parts. The focus of EPT is on the process of optimizing the implementation of the child's function as the context of the child's ecosystem or world. EPT is developed from a phenomenological philosophical perspective, in contrast to traditional perspectives.

    2009-01-01

    When viewed from a large set of criteria such as abundance of energy resources, environmental impacts, low fuel inventory, quantum of waste generated and green house gas emissions, nuclear power can be considered as a large scale sustainable energy source. Among all energy sources, nuclear energy has perhaps the lowest impact on the environment, especially in relation to kilowatt-hr produced, because nuclear plants do not emit harmful gases and produce small quantity of waste. In other words, nuclear energy is the most environmental friendly electricity source. There are no significant adverse effects to water, land, habitat, species and air resources. The present paper discusses the sustainability and feasibility of nuclear power as an eco friendly energy source in the changing and challenging competitive power market. (author)

    With relation to the coal of Indonesia, where the expansion of the use of coal as a substitute for petroleum/plant fuel is aimed at, the paper grasped the situation of coal production/distribution/utilization and environmental problems, and analyzed the situation of the coal utilization/spread by industry including the commercial/residential use. The purpose of the survey is to work out a comprehensive master plan including Japan`s international cooperation for introducing the environmentally-friendly coal utilization system to Indonesia. Coal utilization systems, the introduction of which Indonesia should study in future, were picked up, according to the surveys in fiscal 1993 and 1994. In commercial/residential and small-scale industry sectors, needed is improvement of carbonization technology for production of coal carbonization briquette. Moreover, the introduction of bio-briquette should be studied in the future. In the power generation sector, studies should be made on the introduction of technology for SOx/NOx reduction and technology for coal ash treatment including the effective use of coal ash. For the introduction of coal boilers, the combustion mixed with bagasse, which is abundant in amount, is also necessary. In the coal production sector, coal preparation technology is studied, and a method to select the optimum process was proposed through the simulation. 76 figs., 43 tabs.

    Full Text Available Eco-driving is attractive to the public, not only users of internal-combustion-engine vehicles (ICEVs including hybrid electric vehicles (HEVs but also users of electric vehicles (EVs have interest in eco-driving. In this context, a quantitative evaluation of eco-driving effect of EVs was conducted using a chassis dynamometer (C/D with an “eco-driving test mode.” This mode comprised four speed patterns selected from fifty-two real-world driving datasets collected during an eco-driving test-ride event. The four patterns had the same travel distance (5.2 km, but showed varying eco-driving achievement levels. Three ICEVs, one HEV and two EVs were tested using a C/D. Good linear relationships were found between the eco-driving achievement level and electric or fuel consumption rate of all vehicles. The reduction of CO2 emissions was also estimated. The CO2-reduction rates of the four conventional (including hybrid vehicles were 10.9%–12.6%, while those of two types of EVs were 11.7%–18.4%. These results indicate that the eco-driving tips for conventional vehicles are effective to not only ICEVs and HEVs but also EVs. Furthermore, EVs have a higher potential of eco-driving effect than ICEVs and HEVs if EVs could maintain high energy conversion efficiency at low load range. This study is intended to support the importance of the dissemination of tools like the intelligent speed adaptation (ISA to obey the regulation speed in real time. In the future, also in the development and dissemination of automated driving systems, the viewpoint of achieving the traveling purpose with less kinetic energy would be important.

    The use of an ecosystem service framework for natural resource management has gained increasing traction in the public sector. This is of especial interest in cities as residual ecosystems - typically located along creeks and estuaries, or remaining in scattered pockets throughout the urban area - offer some of the highest value social and economic returns per capita for the land area they occupy, yet are often impractical to manage from more traditional approaches to conservation. We posit that the well-being of humans and other species is the outcome of healthy, functioning ecosystems, and that, from a policy perspective, it is essential to consider services in this context. We arrange ecosystem services into three categories: life-enabling, life-sustaining and life-fulfilling, in a modification to the categories of the Millennium Ecosystem Assessment, and identify additional eco-services unique to urban areas. At local scale, these contribute to the well-being of city residents and positively affect quality of life, forming essential elements of urban liveability. However, dynamics of co-located built and natural environments challenge the capacity of ecosystems to function and provide their full suite of services. Using Sydney as an example, we outline a modular framework of socio-ecological systems and places to show how eco-services supporting liveability can be considered in conceptual and physical space. At a policy level, framing systems-based management objectives that protect, improve and re-discover desirable ecosystem services within the city (as opposed to further increasing the environmental footprint outside), will allow for unique, positive, socially-enabling outcomes for urban centres, in Australia, and globally.

    Full Text Available Purpose – The world is changing and key change agents include climate change and scarcity of resources. The purpose of this paper is to address how New Zealand and tourism could address the future and generate appropriate strategic responses. Design/methodology/approach – Using the process of scenario analysis and drawing upon recent research from the www.tourism2050.com project, this paper describes the circumstances, drivers, economic consequences and key decisions that New Zealand would have to take in order to position itself as an eco paradise. The background to the scenario presumes overarching behaviours in a cooperative world in which resources are scarce. Findings – The scenario portrays a future of collective individualism, where a high degree of personal freedom exists but within the constraints of a world in which there is a scarcity of resources. A communitarian ethos drives policy making with an emphasis on efficient resource use and waste minimisation. New Zealand is a nation favoured by climate change. Environmental intellectual property is one of the nation's key resources and in the spirit of achieving a global environmental equilibrium these technologies are shared with the rest of the world. Life is simple. Competitive individualism is equated with excess and resource waste, while cooperation, harmony, and the continuation of a global cooperative psyche are seen as the foundation stones of the continued, relatively comfortable survival of humanity. Tourism is a luxury and activities are environmentally ethical. Visitors are well-off, purposeful, highly respectful and careful to prove their worth. Originality/value – Eco paradise represents the classic tale of a prisoner's dilemma in which decision makers and consumers ponder the betterment of humankind against individualism. The scenario concludes with a strategic map of the core decisions New Zealand's tourism industry would have to take. The significance of the

    Full Text Available The notion of ecosystem-based disaster risk reduction (DRR has only recently emerged in Indonesia. The Indonesian central government now adopts some policies related to ecosystem-based DRR with formal commitments from local administrations. At the implementation level, various activities have taken place, such as mangrove planting and restoration along the coastline to address the rising sea level and the “one billion trees” program to address the urgent issue of deforestation. These governmental activities have involved local communities that reside in the high-risk area, while nonlocal actors, particularly from the private and the nongovernmental sectors, have contributed as a third element to development. This paper examines space management in the context of Eco-DRR, paying special attention to uncertainty and anxiety in the local communities as the government and private sectors engage in development activities that have significant impacts on their present and future lives. The present study pursues this purpose by means of in-depth interview and focus group discussions (FGD with local leaders in mangrove planting and restoration programs. The study took place in a small island community in a part of the Jakarta Megapolitan Region, Indonesia. The results point out that the community feels left behind due to lack of trust in managing the conservation space. Another issue to be addressed is how to improve the democratization of environment management and livelihood base of the local community. Therefore, building confidence and ameliorating relationships between actors within/without the local community should lead to a better Eco-DRR initiative.

    Besides technical problems the company’s operational constraints that may effect high deficiency for the company is the company - community conflicts. Company - community conflict can also arise depends on the geographic conditions and characteristics of the community itself. Some studies has show that coastal community have higher level of social risk when compared to non-coastal community. Also, the coastal community ussually only rely on what sea provides as their main livelihood. Because of the level of education still contemtible the community couldn’t optimized the potential of their own area. Corporate Social Responsibility (CSR) har emerged as an important approach for addressing the social and environmental impact of company activities. Through CSR program, PT Pertamina EP Asset 3 Tambun Field (PEP) try to form value integration by utilizing resources from the community and the company by making sustainable eco - coastal living in Desa Tambaksari, Karawang, one of PEP working area. Using sustainable livelihood approach begin with compiling data by doing social mapping PEP has initiate the area to becoming Fish Processing Industry Centre. By implementing PDCA in every steps of the program, PEP has multiplied some other programs such as Organic Fish Feed Processing, Seaweed Farming and Waste Bank for Green Coastal Village. These program is PEP’s effort to create a sustainability environment by enhancing the community’s potentials as well as resolving social problems around Tambaksari. The most important result besides getting our license to operate from the community, is the community itself can grow into an eco coastal sustainable system.

    This study was aimed to investigate the effect of bio-organic phosphate either alone or in combination with phosphorus solubilizing bacteria strain (Bacillus MWT-14) on the growth and productivity of two wheat cultivars (Galaxy-2013 and Punjab-2011) along with recommended (150-100NPkgha -1 ) and half dose (75-50NPkgha -1 ) of fertilizers. The combined application of bio-organic phosphate and the phosphorous solubilizing bacteria strain at either fertilizer level significantly improved the growth, yield parameters and productivity of both wheat cultivars compared to non-inoculated control treatments. The cultivar Punjab-2011 produced the higher chlorophyll contents, crop growth rate, and the straw yield at half dose of NP fertilizer; while Galaxy-2013, with the combined application of bio-organic phosphate and phosphorous solubilizing bacteria under recommended NP fertilizer dose. Combined over both NP fertilizer levels, the combined use of bio-organic phosphate and phosphorous solubilizing bacteria enhanced the grain yield of cultivar Galaxy-2013 by 54.3% and that of cultivar Punjab-2011 by 83.3%. The combined application of bio-organic phosphate and phosphorous solubilizing bacteria also increased the population of phosphorous solubilizing bacteria, the soil organic matter and phosphorous contents in the soil. In conclusion, the combined application of bio-organic phosphate and phosphorous solubilizing bacteria offers an eco-friendly option to harvest the better wheat yield with low fertilizer input under arid climate.

    Conference logo The 21st century has been called the century of environmental revolution. Green innovations and environmentally friendly production systems based on physics, chemistry, materials science, and electronic engineering will be indispensable for ensuring renewable energy and establishing a sustainable society. In particular, production design, materials processing, and fabrication technologies such as welding and joining will be very important components of such green innovations. For these reasons, the International Symposium on Materials Science and Innovation for Sustainable Society - eco-materials and eco-innovation for global sustainability - (ECO-MATES 2011) was organized by the Joining and Welding Research Institute (JWRI) and the Center of Environmental Innovation Design for Sustainability (CEIDS), Osaka University. ECO-MATES 2011 was held at Hotel Hankyu Expo Park, Osaka, Japan from 28-30 November 2011. 435 participants from 20 countries around the world attended the symposium. 149 oral presentations including 60 invited talks and 160 posters were presented at the symposium to discuss the latest research and developments in green innovations in relation to environmental issues. The topics of the symposium covered all environmentally related fields including renewable energy, energy-materials, environment and resources, waste and biomass, power electronics, semiconductor, rare-earth metals, functional materials, organic electronics materials, electronics packaging, smart processing, joining and welding, eco-efficient processes, and green applied physics and chemistry. Therefore, 55 full papers concerning green innovations and environmentally benign production were selected and approved by the editorial board and the program committee of ECO-MATES 2011. All papers were accepted through peer review processes. I believe that all the papers have many informative contents. On behalf of the steering committee of the symposium, I would like to express

    The potential toxic impacts of different crystal phases of titania nanoparticles (TNPs) on freshwater biofilms, especially under ultraviolet C irradiation (UVC), are unknown. Here, adverse impacts of three phases (anatase, rutile, and P25, 50 mg L −1 respectively) with UVC irradiation (An-UV, Ru-UV, and P25-UV) on freshwater biofilms were conducted. Characterization experiments revealed that rutile TNPs had a higher water environment stability than anatase and P25 TNPs, possessing a stronger photocatalytic activity under UVC irradiation. Phase-dependent inhibition of cell viability and significant decreases of four- and five-fold in algal biomass at 12 h of exposure were observed compared with unexposed biofilms. Moreover, phase-dependent oxidative stress resulted in remarkably significant reductions (P < 0.01) of the photosynthetic yields of the biofilms, to 40.32% (P25-UV), 48.39% (An-UV), and 46.77% (Ru-UV) of the plateau value obtained in the unexposed biofilms. A shift in community composition that manifested as a strong reduction in diatoms, indicating cyanobacteria and green algae were more tolerant than diatoms when exposed to TNPs. In terms of the toxic mechanisms, rutile TNPs resulted in apoptosis by inducing excessive intracellular reactive oxygen species (ROS) production, whereas P25 and anatase TNPs tended to catalyze enormous acellular ROS lead to cell necrosis under UVC irradiation. - Highlights: • Phase-dependent response of freshwater biofilms to three TNPs was studied with UVC. • Rutile is more stable yet P25 and anatase own better photooxidation level in water. • Decrease in Chl-a and φM and a shift in algae bio-cenosis were phase-dependent. • Phase-dependent stress induced cellular or acellular ROS to reduce cells viability. • Rutile tend to induced apoptosis yet P25 and anatase prefer to cause cell necrosis. - Crystalline-dependent eco-toxicity of TNPs to freshwater biofilms show allotrope of nanoparticles must be considered

    2007-01-01

    This study was intended to develop a computer code of an eco-hydrodynamic model for radionuclides in Lake Obuchi, which is a brackish lake in Rokkasho, Aomori Prefecture and adjacent to nuclear fuel cycle facilities including the first commercial spent-nuclear-fuel reprocessing plant in Japan. Radionuclides introduced into the lake are transferred not only by physical advection an diffusion, but also by bio-chemical activities. The model was planned to include the effects of the low trophic level ecosystem on the transfer of radionuclides as well as the hydraulic movements in the lake. Various parameters necessary for the model description were collected from the lake during 2001 to 2005. Water flow in the lake, including input from the Futamata River and tidal flow from the Pacific Ocean, was simulated by a 3D-hydrodynamic model, and an ecosystem model including phytoplankton and zooplankton was incorporated into the water flow model. Calculations of water movement were carried out using climatic, physicochemical and ecological data collected during January 2001 to December 2002. The numerical simulation results of water current and salinity agreed well with field measurement data. The ecosystem model simulated well the mass fluxes of P, N and observed in the field. The estimated 3 He and 137 Cs concentrations in lake water were in good agreement with the measured data, because the concentrations of both radionuclides were controlled by the mixture of seawater as the higher side member and fresh water as the lower side member. Material balance calculations of both radionuclides in the lake ecosystem showed that they were mainly in the form of dissolved inorganic matter (DIM). However, the fallout 137 Cs deposition pattern in the lake sediment predicted by a long-term simulation did not agree with the measured one. Although input of 137 Cs from the watershed was included in the simulation, its residence time in the watershed was not considered. This meant that

    Participants tasted two cups of coffee, decided which they preferred, and then rated each coffee. They were told (in lure) that one of the cups contained “eco-friendly” coffee while the other did not, although the two cups contained identical coffee. In Experiments 1 and 3, but not in Experiment 2, the participants were also told which cup contained which type of coffee before they tasted. The participants preferred the taste of, and were willing to pay more for, the “eco-friendly” coffee, at least those who scored high on a questionnaire on attitudes toward sustainable consumer behavior (Experiment 1). High sustainability consumers were also willing to pay more for “eco-friendly” coffee, even when they were told, after their decision, that they preferred the non-labeled alternative (Experiment 2). Moreover, the eco-label effect does not appear to be a consequence of social desirability, as participants were just as biased when reporting the taste estimates and willingness to pay anonymously (Experiment 3). Eco labels not only promote a willingness to pay more for the product but also lead to a more favorable perceptual experience of it. PMID:24324623

They were told (in lure that one of the cups contained "eco-friendly" coffee while the other did not, although the two cups contained identical coffee. In Experiments 1 and 3, but not in Experiment 2, the participants were also told which cup contained which type of coffee before they tasted. The participants preferred the taste of, and were willing to pay more for, the "eco-friendly" coffee, at least those who scored high on a questionnaire on attitudes toward sustainable consumer behavior (Experiment 1. High sustainability consumers were also willing to pay more for "eco-friendly" coffee, even when they were told, after their decision, that they preferred the non-labeled alternative (Experiment 2. Moreover, the eco-label effect does not appear to be a consequence of social desirability, as participants were just as biased when reporting the taste estimates and willingness to pay anonymously (Experiment 3. Eco labels not only promote a willingness to pay more for the product but also lead to a more favorable perceptual experience of it.

  4. SCR at bio fuel combustion

    In this project the cause for and the extent of catalyst deactivation has been investigated when using 100 % wood as fuel. The trend of deactivation has been studied as a function of the flue gas temperature, the type of catalyst and the type of combustion technique used. The field tests have been performed in the CFB boiler in Norrkoeping, firing forest residues, and in the boiler in Jordbro, firing pulverized wood (PC). Samples of four different commercial catalyst types have been exposed to flue gas in a test rig connected to the convection section of the boiler. The samples have been analysed at even time intervals. The results after 2 100 hours show a large difference in deactivation trend between the two plants; when using a conventional honeycomb catalyst 80 % of the original activity remains in the CFB boiler but only 20 % remains in the PC boiler. The deactivation in the CFB boiler is about 3 - 4 times faster than what is expected for a conservative design for a coal fired boiler. The results show that the general deactivation trend is similar for the plate and the honeycomb catalyst types. With a catalyst optimised for bio fuels the deactivation rate was about 2/3 compared with a conventional catalyst. At an operating temperature of 315 deg C the deactivation was not as rapid as at 370 deg C. The amount of easily dissolved potassium increases on the surface of the catalyst, especially in the PC boiler, and this is probably the reason for the deactivation. The total amount of potassium in the flue gas is about 5 times higher in the CFB boiler compared with the PC boiler. This indicates that only a certain form of potassium attacks the catalyst and that the total alkali content of the fuel is not a good indicator of the deactivation tendency. The potassium on the catalyst dissolves easily in both water and sulphuric acid. A wash of deactivated catalyst samples with water resulted in higher activity than for the fresh samples if the washing was supplemented

    Three-dimensional (3D) printing technology has been widely used in various manufacturing operations including automotive, defence and space industries. 3D printing has the advantages of personalization, flexibility and high resolution, and is therefore becoming increasingly visible in the high-tech fields. Three-dimensional bio-printing technology also holds promise for future use in medical applications. At present 3D bio-printing is mainly used for simulating and reconstructing some hard tissues or for preparing drug-delivery systems in the medical area. The fabrication of 3D structures with living cells and bioactive moieties spatially distributed throughout will be realisable. Fabrication of complex tissues and organs is still at the exploratory stage. This review summarize the development of 3D bio-printing and its potential in medical applications, as well as discussing the current challenges faced by 3D bio-printing.

    The substitution of natural gas by a renewable equivalent is an interesting option to reduce the use of fossil fuels and the accompanying greenhouse gas emissions, as well as from the point of view of security of supply. The renewable alternative for natural gas is green natural gas, i.e. gaseous energy carriers produced from biomass comprising both biogas and Synthetic Natural Gas (SNG). Via this route can be benefited from all the advantages of natural gas, like the existing dense infrastructure, trade and supply network, and natural gas applications. In this presentation attention is paid to the differences between first generation biogas and second generation bioSNG; the market for bioSNG: grid injection vs. transportation fuel; latest update on the lab- and pilot-scale bioSNG development at ECN; and an overview is given of ongoing bioSNG activities worldwide

  17. Negated bio-events: analysis and identification

    Science.gov (United States)

    2013-01-01

    Background Negation occurs frequently in scientific literature, especially in biomedical literature. It has previously been reported that around 13% of sentences found in biomedical research articles contain negation. Historically, the main motivation for identifying negated events has been to ensure their exclusion from lists of extracted interactions. However, recently, there has been a growing interest in negative results, which has resulted in negation detection being identified as a key challenge in biomedical relation extraction. In this article, we focus on the problem of identifying negated bio-events, given gold standard event annotations. Results We have conducted a detailed analysis of three open access bio-event corpora containing negation information (i.e., GENIA Event, BioInfer and BioNLP’09 ST), and have identified the main types of negated bio-events. We have analysed the key aspects of a machine learning solution to the problem of detecting negated events, including selection of negation cues, feature engineering and the choice of learning algorithm. Combining the best solutions for each aspect of the problem, we propose a novel framework for the identification of negated bio-events. We have evaluated our system on each of the three open access corpora mentioned above. The performance of the system significantly surpasses the best results previously reported on the BioNLP’09 ST corpus, and achieves even better results on the GENIA Event and BioInfer corpora, both of which contain more varied and complex events. Conclusions Recently, in the field of biomedical text mining, the development and enhancement of event-based systems has received significant interest. The ability to identify negated events is a key performance element for these systems. We have conducted the first detailed study on the analysis and identification of negated bio-events. Our proposed framework can be integrated with state-of-the-art event extraction systems. The
