  10. Improvement of economic security management system of municipalities with account of transportation system development: methods of assessment

    Science.gov (United States)

    Khe Sun, Pak; Vorona-Slivinskaya, Lubov; Voskresenskay, Elena

    2017-10-01

    The article highlights the necessity of a complex approach to assess economic security of municipalities, which would consider municipal management specifics. The approach allows comparing the economic security level of municipalities, but it does not describe parameter differences between compared municipalities. Therefore, there is a second method suggested: parameter rank order method. Applying these methods allowed to figure out the leaders and outsiders of the economic security among municipalities and rank all economic security parameters according to the significance level. Complex assessment of the economic security of municipalities, based on the combination of the two approaches, allowed to assess the security level more accurate. In order to assure economic security and equalize its threshold values, one should pay special attention to transportation system development in municipalities. Strategic aims of projects in the area of transportation infrastructure development in municipalities include the following issues: contribution into creating and elaborating transportation logistics and manufacture transport complexes, development of transportation infrastructure with account of internal and external functions of the region, public transport development, improvement of transport security and reducing its negative influence on the environment.

    2017-08-01

    The economic and environmental problems of handling the increasingly huge amounts of urban and/or suburban organic municipal solid wastes MSW, from collection to end disposal, in addition to the big fluctuations in power supply and other energy form costs for the various civilian needs, is studied for Baghdad city, the ancient and glamorous capital of Iraq, and a simple control device is suggested, built and tested by carbonizing these dried organic wastes in simple environment friendly bio-reactor in order to produce low pollution potential, economical and local charcoal capsules that might be useful for heating, cooking and other municipal uses. That is in addition to the solve of solid wastes management problem which involves huge human and financial resources and causes many lethal health and environmental problems. Leftovers of different social level residential campuses were collected, classified for organic materials then dried in order to be supplied into the bio-reactor, in which it is burnt and then mixed with small amounts of sugar sucrose that is extracted from Iraqi planted sugar cane, to produce well shaped charcoal capsules. The burning process is smoke free as the closed burner’s exhaust pipe is buried 1m underground hole, in order to use the subsurface soil as natural gas filter. This process has proved an excellent performance of handling about 120kg/day of classified MSW, producing about 80-100 kg of charcoal capsules, by the use of 200 l reactor volume.

  13. Phthalic acid esters found in municipal organic waste

    DEFF Research Database (Denmark)

    Hartmann, Hinrich; Ahring, Birgitte Kiær

    2003-01-01

    Contamination of the organic fraction of municipal solid waste (OFMSW) with xenobiotic compounds and their fate during anaerobic digestion was investigated. The phthalic acid ester di-(2- ethylhexyl)phthalate (DEHP) was identified as the main contaminant in OFMSW in concentrations more than half.......41-0.79 d(-1), which is much higher than in previous investigations. It can be concluded that the higher removal rates are due to the higher temperature and higher initial concentrations per kg dry matter. These results suggest that the limiting factor for DEHP degradation is the bioavailability, which...... is enhanced at higher temperature and higher degradation of solid organic matter, to which the highly hydrophobic DEHP is adsorbed. The investigated reactor configuration with a thermophilic and a hyper-thermophilic treatment is, therefore, a good option for CD combining high rate degradation of organic...

  14. Potential manure in organic production use: management of municipal organic waste with activators

    Directory of Open Access Journals (Sweden)

    2015-05-01

    Full Text Available The Tiquipaya Municipality produces 22 t day-1 of solid, 63% of it is organic and 37% is inorganic. This waste is disposed of in the Municipal Landfill, rendering it into an environmental and health threat. In order to diminish the negative effects of poor management of municipal solid waste in Tiquipaya, we have carried out the present study in the Tiquipaya municipal composting site, the municipal nursery and the facilities of the PROINPA foundation. At the beginning, the waste composting was done using two treatments: one with organic activator and the other without it. Later the same two methods were used in worm composting, this second process in turn yielded other four treatments two of which included organic activator. After 64 days, within the compost, the activator achieved to reduce 60.02% of the initial volume, leaving a remaining 39.99% of thick material. After the compost had been processed by the worms it was evaluated on the 47th day, we found that the organic activator treatment used from the beginning of the composting phase, yielded a 90.67% decrease from the initial volume of fine matter, compared to the other treatments; it left only 9.33% of thick material. Bio-tests were conducted on barley plants to evaluate the phytotoxicity of the worm compost, these studies showed that treatments with a 50% worm compost concentration had lower germination values (40 to 50%. Whereas treatments that contained 100% of worm compost stood out for their higher yield that ranged from 60 to 70% in their germination values.

    2017-04-01

    In large cities, municipal landfills may have received waste coming from hospitals, but also green waste. The corresponding anthroposol might thus be a source of organic emerging substances such as pharmaceutical or phytosanitary substances. The occurrence and fate of organic emerging substances from such a former landfill in urban areas has been studied as part of a research program dealing with the observation and the monitoring of the environment. Of the 261 substances sought (30 pharmaceutical molecules, 223 phytosanitary products and 8 other emerging substances), 11 pharmaceutical molecules in particular have been quantified in the leachates, 2 endocrine disruptors (bisphenol A and triclosan) and 10 phytosanitary substances. Most of these substances are found also in groundwater immediately downstream of the site (including carbamazepine) at concentrations ranging between 0.1 µg/l and 10 µg/l. The number of detected substances appears much smaller a few hundred meters far from the landfill (bisphenol A and diclofenac in particularly, with concentrations ranging from 0.1 to 1 µg/l and about 0.1 µg/l respectively). Natural attenuation occurs during transfer in the plume, as observed for PAHs or metals. Several mechanisms may explain the natural attenuation of the substances.

  20. Modeling Organic Contaminant Desorption from Municipal Solid Waste Components

    Science.gov (United States)

    Knappe, D. R.; Wu, B.; Barlaz, M. A.

    2002-12-01

    Approximately 25% of the sites on the National Priority List (NPL) of Superfund are municipal landfills that accepted hazardous waste. Unlined landfills typically result in groundwater contamination, and priority pollutants such as alkylbenzenes are often present. To select cost-effective risk management alternatives, better information on factors controlling the fate of hydrophobic organic contaminants (HOCs) in landfills is required. The objectives of this study were (1) to investigate the effects of HOC aging time, anaerobic sorbent decomposition, and leachate composition on HOC desorption rates, and (2) to simulate HOC desorption rates from polymers and biopolymer composites with suitable diffusion models. Experiments were conducted with individual components of municipal solid waste (MSW) including polyvinyl chloride (PVC), high-density polyethylene (HDPE), newsprint, office paper, and model food and yard waste (rabbit food). Each of the biopolymer composites (office paper, newsprint, rabbit food) was tested in both fresh and anaerobically decomposed form. To determine the effects of aging on alkylbenzene desorption rates, batch desorption tests were performed after sorbents were exposed to toluene for 30 and 250 days in flame-sealed ampules. Desorption tests showed that alkylbenzene desorption rates varied greatly among MSW components (PVC slowest, fresh rabbit food and newsprint fastest). Furthermore, desorption rates decreased as aging time increased. A single-parameter polymer diffusion model successfully described PVC and HDPE desorption data, but it failed to simulate desorption rate data for biopolymer composites. For biopolymer composites, a three-parameter biphasic polymer diffusion model was employed, which successfully simulated both the initial rapid and the subsequent slow desorption of toluene. Toluene desorption rates from MSW mixtures were predicted for typical MSW compositions in the years 1960 and 1997. For the older MSW mixture, which had a

    Japanese social security systems and institutions for the elderly, as well as the general attitude toward elderly care services among the Japanese population, have been undergoing a dramatic change. By examining the association between institutional trust, which is a representative element of social capital, and anxiety regarding receiving elderly care, we can uncover clues toward building a more robust social security system for the elderly. This study examines the relationship between institutional trust, in the national social security and municipal healthcare systems for the elderly, and anxiety with respect to receiving elderly care among the general Japanese population. A cross-sectional survey was conducted using a self-administered questionnaire that was returned by mail in January and February 2005. The target population was 4735 community residents aged 20-75 years, who lived in the city of Koka, Shiga, Japan. A total of 2264 questionnaires were included in the analysis. A binominal logistic regression analysis showed that responses of 'trust' [odds ratio (OR): 2.09, 95% confidence interval (95% CI): 1.01-4.30] and 'strongly trust' (OR: 3.80, 95% CI: 1.55-9.31) for the national system were associated with not having anxiety regarding elderly care, compared with the reference category of feeling strongly distrust. However, trust in the municipal system showed no association with this anxiety. These results indicate the importance of developing strategies to increase a common trust in the national care services for the elderly to reduce the anxiety people feel regarding whether they will be able to receive elderly care when required.

  3. TRANSNATIONAL ORGANIZED CRIME. AN (INTERNATIONAL SECURITY PERSPECTIVE

    Directory of Open Access Journals (Sweden)

    Ionel Stoica

    2016-10-01

    Full Text Available For the past two decades organized crime has become a transnational phenomenon, and its impact is still far from being fully known and understood by common people. Its forms of manifestation, whether explicit, or subtle, are permanently evolving and adapting. As a result, its interference with the activities from the legal area makes it difficult to identify and counteract. After a long period of time when it was more a peripheral phenomenon, current transnational organized crime tends to become a major danger to the political, social and economic stability of the states. Through its nature and goals, as well as through the complexity of its forms of manifestation, transnational organized crime represents a major challenge for the state and nonstate organizations that deal with national and international security This paper focuses on the phenomenon starting from some of the most influent theories in international relations, presents the current features of transnational organized criminal groups and analyzes the causes and the favoring factors of the phenomenon, as well as the impact of the phenomenon upon national and international security at political, economic-financial and military level. The approach is an interdisciplinary one and also covers the nexus between transnational organized crime and international terrorism.

    2012-03-01

    In this work, the elemental content (C, N, H, S, O), the organic matter content and the calorific value of various organic components that are commonly found in the municipal solid waste stream were measured. The objective of this work was to develop an empirical equation to describe the calorific value of the organic fraction of municipal solid waste as a function of its elemental composition. The MSW components were grouped into paper wastes, food wastes, yard wastes and plastics. Sample sizes ranged from 0.2 to 0.5 kg. In addition to the above individual components, commingled municipal solid wastes were sampled from a bio-drying facility located in Crete (sample sizes ranged from 8 to 15 kg) and were analyzed for the same parameters. Based on the results of this work, an improved empirical model was developed that revealed that carbon, hydrogen and oxygen were the only statistically significant predictors of calorific value. Total organic carbon was statistically similar to total carbon for most materials in this work. The carbon to organic matter ratio of 26 municipal solid waste substrates and of 18 organic composts varied from 0.40 to 0.99. An approximate chemical empirical formula calculated for the organic fraction of commingled municipal solid wastes was C(32)NH(55)O(16). Copyright © 2011 Elsevier Ltd. All rights reserved.

    Purpose - Previous research has shown that user-oriented care predicts older persons' satisfaction with care. What is yet to be researched is how senior management facilitates the implementation of user-oriented care. The purpose of this study is to investigate the organizing principles and management climate characterizing successful elderly care. Design/methodology/approach - The department in one highly ranked municipality was selected and compared with a more average municipality. On-site in-depth semi-structured interviews with department managers and participatory observations at managers' meetings were conducted in both municipalities. Findings - Results revealed three key principles for successful elderly care: organizing care from the viewpoint of the older person; recruiting and training competent and autonomous employees; instilling a vision for the mission that guides operations at all levels in the organization. Furthermore, using climate theory to interpret the empirical material, in the highly successful municipality the management climate was characterized by affective support and cognitive autonomy, in contrast to a more instrumental work climate primarily focusing on organizational structure and doing the right things characterizing the more average municipality. Originality/value - The authors suggest that guiding organizing principles are intertwined with management climate and that there are multiple perspectives that must be considered by the management, that is, the views of the older persons, the co-workers and the mission. These results can guide future care quality developments, and increase the understanding of the importance of organizational climate at the senior management level.

    2015-01-01

    In healthcare, information security is a key aspect of protecting a patient's privacy and ensuring systems availability to support patient care. Security managers need to measure the performance of security systems and this can be achieved by using evidence-based metrics. In this paper, we describe the development of an evidence-based security metrics scorecard specific to healthcare organizations. Study participants were asked to comment on the usability and usefulness of a prototype of a security metrics scorecard that was developed based on current research in the area of general security metrics. Study findings revealed that scorecards need to be customized for the healthcare setting in order for the security information to be useful and usable in healthcare organizations. The study findings resulted in the development of a security metrics scorecard that matches the healthcare security experts' information requirements.

    Codigestion of organic wastes is a technology that is increasingly being applied for simultaneous treatment of several solid and liquid organic wastes. The main advantages of this technology are improved methane yield because of the supply of additional nutrients from the codigestates and more efficient use of equipment and cost-sharing by processing multiple waste streams in a single facility. Many municipal wastewater treatment plants (WWTPs) in industrialized countries currently process wastewater sludge in large digesters. Codigestion of organic wastes with municipal wastewater sludge can increase digester gas production and provide savings in the overall energy costs of plant operations. Methane recovery also helps to reduce the emission of greenhouse gases to the atmosphere. The goal of this literature survey was to summarize the research conducted in the last four years on anaerobic codigestion to identify applications of codigestion at WWTPs. Because the solids content in municipal wastewater sludge is low, this survey only focuses on codigestion processes operated at relative low solids content (slurry mode). Semi-solid or solid codigestion processes were not included. Municipal wastewater sludge, the organic fraction of municipal solid waste, and cattle manure (CAM) are the main wastes most often used in codigestion processes. Wastes that are codigested with these main wastes are wood wastes, industrial organic wastes, and farm wastes. These are referred to in this survey as codigestates. The literature provides many laboratory studies (batch assays and bench-scale digesters) that assess the digestibility of codigestates and evaluate the performance and monitoring of codigestion, inhibition of digestion by codigestates, the design of the process (e.g., single-stage or two-stage processes), and the operation temperature (e.g., mesophilic or thermophilic). Only a few reports on pilot- and full-scale studies were found. These evaluate general process

    Full Text Available Information security is one of the major challenges of the information and knowledge based society. The preoccupation of organizations to ensure the security of information in the digital environment has led to the emergence of specific standards in the field. Thus, ISO 27000 brings together reference standards in the field. Starting from ISO 27001, which summarizes policies and procedures on physical, legal and technological security risks, this paper looks at the steps the organization must undertake to implement the standards.

On top of this is the size of the education organizations. The larger the population in an education organization, the more the problem of information and security become very clear. Thus, they have been obliged to comply with information security issues and adopt the national or international standard. The case is quite different when the population size of the education organization is smaller. In such education organizations, they use social security numbers as student ID, and issue administrative rights to faculty and lab managers – or they are not aware of the Family Educational Rights and Privacy Act (FERPA – and release some personal information.The problem of education organization security is widely open and depends on the IT staff and their information security knowledge in addition to the education culture (education, scholarships and services has very special characteristics other than an enterprise or comparative organizationThis paper is part of a research to develop an “Education Organization Baseline Control Protection and Trusted Level Security.” The research has three parts: Adopting (standards, Testing and Modifying (if needed.

  8. Possible interactions between recirculated landfill leachate and the stabilized organic fraction of municipal solid waste.

    Science.gov (United States)

    Calabrò, Paolo S; Mancini, Giuseppe

    2012-05-01

    The stabilized organic fraction of municipal solid waste (SOFMSW) is a product of the mechanical/biological treatment (MBT) of mixed municipal solid waste (MMSW). SOFMSW is considered a 'grey' compost and the presence of pollutants (particularly heavy metals) and residual glass and plastic normally prevents agricultural use, making landfills the typical final destination for SOFMSW. Recirculation of leachate in landfills can be a cost-effective management option, but the long-term sustainability of such a practice must be verified. Column tests were carried out to examine the effect of SOFMSW on leachate recirculation. The results indicate that organic matter may be biologically degraded and metals (copper and zinc) are effectively entrapped through a combination of physical (adsorption), biological (bacterial sulfate reduction), and chemical (precipitation of metal sulfides) processes, while other chemicals (i.e. ammonia nitrogen and chloride) are essentially unaffected by filtration through SOFMSW.

The article discusses the importance of such an element of economic security (including the financial security as the accounting and control as well as their possible violations. The authors substantiate their position on the relationship of the violations of accounting and control and also the internal theft, other economic crimes and their negative consequences. The analysis of the existing national and foreign sources related to the subject of the study is carried out. The conclusion is made about the lack of modern research devoted to the study of the protective properties of accounting, control and their violations, which condition economic crimes. The methodological tools of the research include dialectic method, systemic analysis, complex sociological methods: the analysis of the legal sources, of statistical information and judicial practice. On the basis of the analysis of criminal cases, financial statements, publications media, the authors made the conclusion about the conditionality of the theft in the organizations as there are the violations of accounting and control, low efficiency of control and auditing, of preventive measures for neutralization of the violations of accounting and control from the services of economic security, accounting offices, auditing and law enforcement services. The recommendations for the optimization of this work are introduced. They can be used by accounting departments, auditing bodies, fiscal authorities at the municipal and regional level and by law enforcement officials. The economic security is necessary for any organizations regardless of their forms of ownership, ranging from government organizations to small kiosks. The difference will only consist in the means and methods.

    Landfilling is the most common method for disposing of municipal solid waste (MSW) in North America. MSW consists of nonbiodegradable fractions as well as biodegradable fractions known as the organic fraction of municipal solid waste (OFMSW). Because of its high moisture content, OFMSW produces large amounts of leachate in landfills. If not treated properly, leachates can pollute groundwater and negatively affect health and the environment. This paper reported on a study that was conducted to determine the effects of microwave (MW) irradiation on the solubilization of organic fraction of municipal solid waste (OFMSW) at different temperatures, MW ramp times, and supplemental water addition (SWA). The objective was to enhance solubilization before anaerobic digestion (AD). MW pretreatment resulted in higher soluble chemical oxygen demand (sCOD), proteins and sugars in the supernatant phase. The highest increase in sCOD was achieved at 175 degrees C. For the same condition, the free liquid volume from bound water released from OFMSW into the supernatant was about 1.39 times higher than the control. The increase in potentially bio-available sCOD increased significantly to more than 200 per cent after microwaving at high temperature. It was concluded that microwaving of OFMSW at high temperature with SWA provides the best conditions for waste solubilisation in preparation for anaerobic digestion. The actual effect of MW pre-treatment on the anaerobic digestion process has yet to be determined. 49 refs., 5 tabs., 3 figs.

    The high liquid content in fruit and vegetable wastes makes it convenient to mechanically separate these wastes into mostly liquid and solid fractions by means of pretreatment. Then, the liquid fraction can be treated using a high-rate anaerobic biofilm reactor to produce biogas, simultaneously reducing the amount of solids that must be landfilled. In this work, the specific composition of municipal solid waste (MSW) in a public market was determined; then, the sorted organic fraction of municipal solid waste was treated mechanically to separate and characterize the mostly liquid and solid fractions. Then, the mesophilic anaerobic digestion for biogas production of the first fraction was evaluated. The anaerobic digestion resulted in a reduced hydraulic retention time of two days with high removal of chemical oxygen demand, that is, 88% on average, with the additional benefit of reducing the mass of the solids that had to be landfilled by about 80%.

    Several characteristics make anaerobic digestion of the organic fraction of municipal solid waste (OFMSW) difficult. By co-digestion of OFMSW with several other waste types it will be possible to optimize the anaerobic process by waste management. The co-digestion concept involves the treatment...... of several waste types in a single treatment facility. By combining many types of waste it will be possible to treat a wider range of organic waste types by the anaerobic digestion process (figure 1). Furthermore, co-digestion enables the treatment of organic waste with a high biogas potential that makes...... the operation of biogas plants more economically feasible (Ahring et al., 1992a). Thus, co-digestion gives a new attitude to the evaluation of waste: since anaerobic digestion of organic waste is both a waste stabilization method and an energy gaining process with production of a fertilizer, organic waste...

    Full Text Available About 1% of New Zealand farmland is managed organically. Nitrogen is the nutrient most likely to limit organic crop production. A potential solution is incorporation of compost to supply N. About 726,000 t of municipal garden and kitchen wastes are sent to landfills annually. Composting offers a means of reducing the impact of landfill wastes on the wider environment. Organically certified compost (N content typically 2% to 2.5% is available from some municipal composting plants. To be effectively used on organic farms, the rate of N release (mineralization must be known. Laboratory incubations were conducted to quantify mineralization of compost N under controlled (temperature and moisture conditions. Nitrogen availability and crop yields from a one-off application of compost (25–100 t·ha−1 were also assessed in two field trials (using cereal and forage crops. The results suggested that a relatively small part (13%–23% of compost N was used by the crops in 3–4 years. Much of this was mineral N present at the time of application. Mineralization rates in the laboratory and field studies were much lower than expected from published work or compost C:N ratio (considered an important indicator of N mineralization potential of composts.

    2005-01-01

    Full text: Securing decommissioning funds requires that the financial resources set aside for the purpose of decommissioning be managed prudently. Decommissioning of nuclear power plant is prescribed by National Atomic Laws or by other nuclear legislation. It is a mandatory operation. The operators of nuclear power plants set money aside for that purpose. This is known as 'Decommissioning reserve fund'. Decommissioning implies costs very distant in time. Thus, it is obvious, from an economic point of view, that the funds set aside should be managed. As decommissioning is mandatory, the funds accumulated should be secured. In others words, they should be available when needed. Availability of funds is influenced by endogenous and exogenous factors. Endogenous factors are a matter of design of the reserve funds. They include the management of the funds, its monitoring and control... Availability of funds is influenced by these factors, depending on the rules to which the behaviour of the manager of the funds is subjected. In contrast, exogenous factors deal with the energy context. These factors are mainly the electricity sector organisation and/or the overall economic situation. They are decisive factors of the economic performance of the reserve fund for a given design. Therefore, the requirement of availability of funds, when needed, is a matter of compatibility between the design of the decommissioning funds and the electricity context. Put differently, reserve fund's design need to be consistent with the electricity context's features in respect of the availability of funds. Current reserve funds were designed in a context of monopoly regime. In this context, availability of decommissioning funds was not questionable. At least, as far as the design of the reserve funds is concerned. This is because nuclear generator didn't confront any competition pressure. Electricity prices were set trough rate base mechanism, and all the business risks were borne by the

    The organic fraction of municipal solid waste represents a potential feedstock to be treated through biorefining. However, the process feasibility strongly depends on the effectiveness of a chemical pretreatment. Consequently, experimentation aimed at choosing the optimal type of reagent (alkali or acids) and optimal operating conditions was carried out. The best results were obtained using NaOH at room temperature. Solubilization data are in good agreement with a kinetics based on two competing reactions. Simulation of the overall process (pretreatment and acidogenic fermentation) taking place in two CFSTR reactors shows that an optimum ratio exists between the hydraulic residence times of the two stages of the process.

    The organic matter, as well as nitrogen and phosphorus, are nutrient substances. Their excess concentrations in water receiving bodies lead to eutrophication, moreover, the nitrogen content in water bodies is standardized according the sanitary-toxicological criterion of harmfulness: NH 4 + -N ≤0,39-2,0 mgl - , NO 3 -N ≤9,1-10 mgl - . The municipal wastewater contain, usually, organic matter estimated by BOD 150-200 mgl - , and COD 300-400 mgl - , the nitrogen compounds 50-60 mgl - , and NH 4 + -N 20-25 mgl - . NO x -N are practically absent. Their presence indicated on discharge of industrial wastewater. The total phosphorus is present in the concentration of 15 mgl - , PO 4 - - P 5-8 mgl - . Activated sludge process has been most widely used in the USSR for municipal wastewater treatment. The activated sludge is biocenoses of heterotrophic and auto trophic microorganisms. They consume nutrient matters, transferring pollution of wastewater by means of enzyme systems in acceptable forms. C, N and P-containing matters are removed from wastewater by biological intake for cell synthesis. Moreover C- containing matters are removed by oxidation to CO 2 and H 2 O. P-containing compounds under definite conditions associate with solid fraction of activated sludge and thus simultaneously removed from wastewater. The removal of nitrogen in addition to biosynthesis is carried out only in the denitrification process, when oxygen of NO x -N is used for oxidation of organic matter and produced gaseous nitrogen escapes into the atmosphere

    In this study, the ability of the organic fraction of municipal solid wastes (OFMSW) to enhance heavy metal uptake of maize shoots compared with ethylenediamine disuccinic acid (EDDS) was tested on soil contaminated with heavy metals. Soils treated with OFMSW and EDDS significantly increased the concentration of heavy metals in maize shoots (increments of 302%, 66%, 184%, 169%, and 23% for Cr, Cu, Ni, Zn, and Pb with respect to the control and increments of 933%, 482%, 928%, 428%, and 5551% for soils treated with OFMSW and EDDS, respectively). In soil treated with OFMSW, metal uptake was favored because of the high presence of dissolved organic matter (DOM) (41.6x than soil control) that exhibited ligand properties because of the high presence of carboxylic acids. Because of the toxic effect of EDDS on maize plants, soil treated with OFMSW achieved the highest extraction of total heavy metals. - Organic fraction of MSW affects the bioavailability of heavy metals in soil.

    Municipal solid waste (MSW) disposal is a major environmental concern worldwide. Among the environmentally sound technologies for the treatment of MSW, composting in the form of anaerobic digestion (AD) appears as a suitable alternative that offers the advantage of rapid stabilization of organic matter, reduction in waste volume, production of methane, and minimal environmental impacts in comparison to land filling and incineration. Yet, although outstanding advances in anaerobic digestion of solid substrate have been made in the last 10 years, some development areas are lagging, including the fast and reliable process start-up in terms of type of inocula and overall start-up strategies. The present study investigates the start-up and operation of bench-scale anaerobic digesters treating the source-sorted organic fraction of municipal solid waste. The experimental program consisted of starting up two digesters in parallel. Three consecutive interventions in the start-up program were implemented to achieve steady state. Start-up was relatively slow indicating the seed obtained from an operating anaerobic wastewater treatment plant was not suitable. The use of cattle manure together with effluent dilution reduced the acclimation period (Author.)

    Different process strategies for anaerobic digestion of the organic fraction of municipal solid waste (OFMSW) are reviewed weighing high-solids versus low-solids, mesophilic versus thermophilic and single-stage versus multi-stage processes. The influence of different waste characteristics...... such as composition of biodegradable fractions, C:N ratio and particle size is described. Generally, source sorting of OFMSW and a high content of food waste leads to higher biogas yields than the use of mechanically sorted OFMSW. Thermophilic processes are more efficient than mesophilic processes in terms of higher...... biogas yields at different organic loading rates (OLR). Highest biogas yields are achieved by means of wet thermophilic processes at OLRs lower than 6 kg-VS(.)m(-3) d(-1). High-solids processes appear to be relatively more efficient when OLRs higher than 6 kg-VS(.)m(-3) d(-1) are applied. Multi...

    Full Text Available Concentrations of indicator organisms in the stored rainwater in the Makana Municipality, South Africa. The United Nations Millennium Development Goals’ target 7C seeks to halve the number of people without sustainable access to safe drinking water and basic sanitation by 2015. At present, supply of safe drinking water is still intermittent in some parts of South Africa due to infrastructural problems and droughts. Rainwater harvesting could be a solution to this problem. Microbial rainwater quality was evaluated in the Makana Municipality, South Africa. Enumerations were done using the membrane-filtration technique with m-FC and m-Endo agar and the indole test. One sample contained E. coli at 1 colony-forming unit/100 cm3, while the faecal coliform concentrations ranged from 0 to 98 colony-forming units/100 cm3 in all samples. The total coliform concentrations ranged from 0 to 200 colony-forming units/100 cm3. On-site treatment of rainwater was insufficient due to missing first-flush devices. Rainwater is suitable for subsurface irrigation of vegetable gardens. Strategies are required to involve the community in the design and building of new rainwater harvesting systems.

    Waste is currently main problem experienced by cities all over the world. The waste has brought negative impacts on public health, environment, development and social of the cities. However, there must be solutions to overcome the piles of waste in case the individual citizens or community-based organization wisely deal with the problem. In the municipal area of Medan in the Province of North Sumatra, there is sort of organization established by community-based organization (CBO) so-called Bank Sampah or Waste Bank which is placed as a flatform for the member to do business of waste materials by collecting them from households around, sorting the materials into waste categories and ended up by purchasing and selling them to make some money. The organization is not merely a flatform for doing a business of waste materials yet the media for other social activities and efforts of reaching social and family welfare. The study is conducted in some sites of such organization activities in the city, and there are some observations of how the community run the business and in the same time arranging other social activities. The study tries to portray the activities and analyzes the means and the significancy of the CBO on reducing waste problems in the city.

    A bench-scale investigation was conducted to select external organic wastes and mixing ratios for co-digestion with municipal sludge at the F. Wayne Hill Water Resources Center (FWHWRC), Gwinnett County, GA, USA to support a combined heat and power (CHP) project. External wastes were chosen and used subject to two constraints: a) digester retention time no lower than 15 d; and b) total biogas (methane) production not to exceed a specific target level based on air permit constraints on CO2 emissions. Primary sludge (PS), thickened waste activated sludge (TWAS) and digested sludge collected at the FWHWRC, industrial liquid waste obtained from a chewing gum manufacturing plant (GW) and dewatered fat-oil-grease (FOG) were used. All sludge and waste samples were characterized and their ultimate digestibility was assessed at 35 °C. The ultimate COD to methane conversion of PS, TWAS, municipal sludge (PS + TWAS; 40:60 w/w TS basis), GW and FOG was 49.2, 35.2, 40.3, 72.7, and 81.1%, respectively. Co-digestion of municipal sludge with GW, FOG or both, was evaluated using four bench-scale, mesophilic (35 °C) digesters. Biogas production increased significantly and additional degradation of the municipal sludge between 1.1 and 30.7% was observed. Biogas and methane production was very close to the target levels necessary to close the energy deficit at the FWHWRC. Co-digestion resulted in an effluent quality similar to that of the control digester fed only with the municipal sludge, indicating that co-digestion had no adverse effects. Study results prove that high methane production is achievable with the addition of concentrated external organic wastes to municipal digesters, at acceptable higher digester organic loadings and lower retention times, allowing the effective implementation of CHP programs at municipal wastewater treatment plants, with significant cost savings.

    The position towards the environment of the local organizations has envolved parallely to the restlessness of the society in general, taking every time a greater importance in this matter. From the municipal point of view, the management of the environment is not just a mere idea of protection of the nature or of certain forms of natural life in danger; now, the environmental management includes more complex aspects, like the balanced management of the natural resources and the general aim of the quality of life. The City councils, in their paper of public institutions, have much to say like centers where a great part of the life and activity of the population is developed, and the physical and geographic frame where the environmental problems have their seat.

    The hydrogen production from the organic fraction of municipal solid waste (OFMSW) by anaerobic mixed culture fermentation was investigated using batch experiments at 37 C. Seven varieties of typical individual components of OFMSW including rice, potato, lettuce, lean meat, oil, fat and banyan leaves were selected to estimate the hydrogen production potential. Experimental results showed that the boiling treated anaerobic sludge was effective mixed inoculum for fermentative hydrogen production from OFMSW. Mechanism of fermentative hydrogen production indicates that, among the OFMSW, carbohydrates is the most optimal substrate for fermentative hydrogen production compared with proteins, lipids and lignocelluloses. This conclusion was also substantiated by experimental results of this study. The hydrogen production potentials of rice, potato and lettuce were 134 mL/g-VS, 106 mL/g-VS, and 50 mL/g-VS respectively. The hydrogen percentages of the total gas produced from rice, potato and lettuce were 57-70%, 41-55% and 37-67%. (author)

    High-solids anaerobic digestion (HSAD) processes, when applied to different types of organic fractions of municipal solid waste (OFMSW), may easily be subjected to inhibition due to organic overloading. In this study, a new approach for predicting these phenomena was proposed based on the estimation of the putrescibility (oxygen consumption in 20 h biodegradation, OD(20)) of the organic mixtures undergoing the HSAD process. Different wastes exhibiting different putrescibility were subjected to lab-scale batch-HSAD. Measuring the organic loading (OL) as volatile solids (VS) was found unsuitable for predicting overload inhibition, because similar VS contents corresponded to both inhibited and successful trials. Instead, the OL calculated as OD(20) was a very good indicator of the inhibiting conditions (inhibition started for OD(20)>17-18 g O(2)kg(-1)). This new method of predicting inhibition in the HSAD process of diverse OFMSW may be useful for developing a correct approach to the technology in very different contexts.

    The Municipal Solid Waste (MSW) Options Report explored different MSW management options for 3 community sizes: 20,000, 80,000 and 200,0000 people. It was released at a time when many communities were developing waste management plans to cost-effectively reduce environmental impacts and conserve landfill capacity. The purpose of this report was to provide a greater understanding on the environmental, social, economic, energy recovery/utilization and greenhouse gas (GHG) considerations of MSW management. The report also demonstrated the interrelationships between the management of organics and residuals. It was based on information from existing waste diversion and organics management options and emerging residual treatment technology options. The following organics management and residual treatment disposal options were evaluated: composting; anaerobic digestion; sanitary landfills; bioreactor landfills; and thermal treatment. Composting was examined with reference to both source separated organics (SSO) and mixed waste composting. SSO refers to the separation of materials suitable for composting solid waste from households, while mixed waste composting refers to the manual or mechanical removal of recyclable material from the waste, including compost. The composting process was reviewed along with available technologies such as non-reactor windrow; aerated static pile; reactor enclosed channel; and, container tunnel. An evaluation of SSO and mixed waste composting was then presented in terms of environmental, social, financial and GHG impacts. refs., tabs., figs.

    Full Text Available Soil fertility properties, irrigation water quality, mineral nutrition, and some vegetables mineral composition were studied in the frame of a project regarding yield quality monitoring in certified organic vegetable farms, in two farms placed on the outskirts of Bucharest Municipality which provide products for the town’s organic market. Chemical analysis of the soil samples collected from the two farms reflects a good fertility, close to the natural one of this region soils, with well-balanced organic matter, total nitrogen, accessible phosphorus and potassium contents. The nitrates contents concord with the plants nutrition demands and don’t present the risk to accumulate in vegetables or to leach into the groundwater. Slightly increased microelements, both total and soluble forms, occur. Soil microbiological properties are favorable for vegetable plants growth. A good biodiversity is noticed. There are differences between soil properties in open field and greenhouses, induced both by the type and degree of mechanical works and materials applied for fertilization and plant protection. Good conditions are generally created for plants mineral nutrition. Mineral nutrition status of the vegetables grown in organic conditions, assessed by the leaves mineral composition, doesn’t differ from the one of the vegetables grown in conventional conditions. The vegetables (fresh material harvested from the two studied farms have good, even high, concentrations of mineral elements important for the yield nutritional quality. The excessive microelements quantities noticed in soil don’t transfer in the yield, so the latter quality and nutritional properties are not altered.

    2015-01-01

    Previous research indicates that companies manage workplace health in various ways, but more in-depth empirical knowledge of how workplace health promotion (WHP) is managed in public sector organizations is needed. The aim of this study was to explore how WHP is managed and incorporated into the general management system in two large Swedish municipal organizations. A qualitative descriptive approach was used. Fourteen senior managers were purposefully selected and interviewed using semi-structured interviews. Documents were used as supplementary data. All data were analysed using qualitative content analysis. The management of WHP was described as a set of components that together contribute to the organization's capacity for WHP. The informants described WHP as dominated by fitness programmes and as following a problem-solving cycle, in which the annual employee survey emerged as an important managerial tool. Achieving feasible WHP measures and appropriate follow-ups were described as challenges. The provision of leadership competence for WHP and use of supportive resources were described as additional components. The WHP management approach needs to be broadened to include work environment and organizational factors. Further integration with occupational health and safety and the general management system in the organizations is also needed.

    Characteristics of non-methane organic compounds (NMOCs) emissions during the anaerobic decomposition of untreated (APD-0) and four aerobically pretreated (APD-20, APD-39, APD-49, and APD-63) samples of municipal solid waste (MSW) were investigated in laboratory. The cumulative mass of the NMOCs of APD-20, APD-39, APD-49, and APD-63 accounted for 15%, 9%, 16%, and 15% of that of APD-0, respectively. The intensities of the NMOC emissions calculated by dividing the cumulative NMOC emissions by the quantities of organic matter removed (Q(VS)) decreased from 4.1 mg/kg Q(VS) for APD-0 to 0.8-3.4 mg/kg Q(VS) for aerobically pretreated MSW. The lipid and starch contents might have significant impact on the intensity of the NMOC emissions. Alkanes dominated the NMOCs released from the aerobically pretreated MSW, while oxygenated compounds were the chief component of the NMOCs generated from untreated MSW. Aerobic pretreatment of MSW prior to landfilling reduces the organic content of the waste and the intensity of the NMOC emissions, and increases the odor threshold, thereby reducing the environmental impact of landfills.

    Full Text Available The safety provided by a well configured firewall is no excuse for neglecting the standard security procedures;setting up and installing a firewall is the first line of defense and not a full proof solution, auditing being only onecomponent of the system, whilst the other is protecting the resources and when we consider auditing as being theprocess of recording certain events that take place on a computer or within a network, we must come to the conclusionthat this is the only technique that allows us to identify the source of a possible issue within the network.Information security is used as a means to protect the intellectual property rights, whilst the main objective insetting up an information security system is to enlist the confidence of prospective business partners. In accordancewith the legal requisites and the principle of maximizing one’s investment, regardless of the many forms it could take,or the means through which it is stored, transmitted or distributed, information must be protected.Information security is not only a technical problem, but mainly a managerial issue, as the security standard,ISO/IEC 17799 meets the needs of any type of organization, be it public or private, through a series of practices relatedto the management of information security.This paper aims to present the process of taking entry data from a plethora of programs and storing it in acentral location. Due to its flexibility, this process can be a useful auditing instrument, as long as we are familiar withthe way it works and how the events are recorded.

  12. Behavior of selected organic pollutants in municipal waste during the mechanical-biological progress of composting

    Drahosch, W.

    1998-06-01

    Municipal waste was investigated during the mechanical-biological process of composting. Waste from Burgenland is treated mechanically and biologically to reduce organic matter in the material and to keep gas building potential low before deposition. Samples were taken and analyzed during a period of 80 days. The parameters: temperature, dry-weight, glow loss, ammonium, nitrate and phenolic substances were measured to follow the composting process. It was found that the process was almost finished after a period of 40 days in which the material was breathed intensively. The content of polycyclic aromatic hydrocarbons and polychlorinated phenols decreased slightly. It was not clear whether this was due to microbiological activity or blowing-out effects. Polychlorinated biphenyls were found to be stable during composting. The concentrations were considered as high. Hepta- and octachlorinated dibenzodioxines were formed during the first 10 days. The increase of octachlorinated dibenzodioxin was threefold. Other dioxines and furanes remained unchanged. Finally it was found out that mechanical-biological waste treatment is insufficient in order to reduce organic pollutants effectively. (author)

    Abstract Treatment wetlands have become an attractive option for the removal of nutrients from municipal wastewater effluents due to their low energy requirements and operational costs, as well as the ancillary benefits they provide, including creating aesthetically appealing spaces and wildlife habitats. Treatment wetlands also hold promise as a means of removing other wastewater-derived contaminants, such as trace organic contaminants and pathogens. However, concerns about variations in treatment efficacy of these pollutants, coupled with an incomplete mechanistic understanding of their removal in wetlands, hinder the widespread adoption of constructed wetlands for these two classes of contaminants. A better understanding is needed so that wetlands as a unit process can be designed for their removal, with individual wetland cells optimized for the removal of specific contaminants, and connected in series or integrated with other engineered or natural treatment processes. In this article, removal mechanisms of trace organic contaminants and pathogens are reviewed, including sorption and sedimentation, biotransformation and predation, photolysis and photoinactivation, and remaining knowledge gaps are identified. In addition, suggestions are provided for how these treatment mechanisms can be enhanced in commonly employed unit process wetland cells or how they might be harnessed in novel unit process cells. It is hoped that application of the unit process concept to a wider range of contaminants will lead to more widespread application of wetland treatment trains as components of urban water infrastructure in the United States and around the globe.

    Municipal solid waste (MSW) generation has been growing in many countries, which has led to numerous environmental problems. Converting MSW into a valuable biochar-based by-product can manage waste and, possibly, improve soil fertility, depending on the soil properties. In this study, MSW-based biochars, collected from domestic waste materials and kerbsides in two Sydney's regions, were composted and pyrolysed at 450°C, 550°C and 650°C. The characteristics of the organic components and their interactions with mineral phases were investigated using a range of analytical techniques, with special attention given to polycyclic aromatic hydrocarbons and heavy metal concentrations. The MSW biochar prepared at 450°C contained the most complex organic compounds. The highest concentration of fixed C, indicating the stability of biochar, was detected in the high-temperature-biochar. Microscopic analysis showed development of pores and migration of mineral phases, mainly Ca/P/O-rich phases, into the micro-pores and Si/Al/O-rich phases on the surface of the biochar in the MSW biochar produced at 550°C. Amalgamation of organic phases with mineral compounds was observed, at higher pyrolysis temperatures, indicating chemical reactions between these two phases at 650°C. XPS analysis showed the main changes occurred in C and N bonds. During heat treatment, N-C/C=N functionalities decomposed and oxidized N configurations, mainly pyridine-N-oxide groups, were formed. The majority of the dissolved organic carbon fraction in both MSW biochar produced at 450°C and 550°C was in the form of building blocks, whereas LMW acids was the main fraction in high-temperature-biochar (59.9%).

    Full Text Available The derbent organization which was established in order to protect caravans and trade-roads and developed from the “Tutkavul” system in Ilhanlıs, is one of the important roads of settlement in the Ottoman State. The derbent facilities, surrounded by walls, are built around intersections of the main roads and in places with central importance; therefore, the inhabitants live in village recorded as the ones responsible for various services are exempted from some or all taxes. Derbents are not only important facilities they also provide security for the region and trade-route but they played a role in enabling settlement in isolated places to Although they were significant in terms of their functions, their organization begins to get out of order in 17th century, the residents have to leave their houses since they are subjected to pressure of bandits. In 18th century the state tried to put this malfunction in order. In spite of all the measures taken the derbents. In couldn’t be brought back to its old form and so neglected. The reform movements that began with the administrative reforms “Tanzimat” enable derbent organizations to be removed and in modern sense security organization is founded; in this framework inns and derbents in some certain points are transformed into gendarme post

    The discharge of inadequately treated municipal wastewater has aggravated the pollution load in developing countries including Ethiopia. Conventional wastewater treatment methods that require high capital and operational costs are not affordable for many developing nations, including Ethiopia. This study aimed to investigate the performance of two high-rate algal ponds (HRAPs) in organic pollutant removal from primary settled municipal wastewater under highland tropical climate conditions in Addis Ababa. The experiment was done for 2 months at hydraulic retention times (HRTs) ranging from 2 to 8 days using an organic loading rates ranging 333-65 kg {BOD}5 /ha/day using two HRAPs, 250 and 300 mm deep, respectively. In this experiment, Chlorella sp., Chlamydomonas sp., and Scenedesmus sp., the class of Chlorophyceae, were identified as the dominant species. Chlorophyll-a production was higher in the shallower ponds (250 mm) throughout the course of the study, whereas the deeper HRAP (300 mm) showed better dissolved oxygen production. The maximum COD and {BOD}5 removal of 78.03 and 81.8% was achieved at a 6-day HRT operation in the 250-mm-deep HRAP. Therefore, the 300-mm-deep HRAP is promising for scaling up organic pollutant removal from municipal wastewater at a daily average organic loading rate of 109.3 kg {BOD}5 /ha/day and a 6-day HRT. We conclude that the removal of organic pollutants in HRAP can be controlled by pond depth, organic loading rate, and HRT.

    This paper examines the effect of mixing on the performance of thermophilic anaerobic digestion of source-sorted organic fraction of municipal solid waste during the start-up phase and in the absence of an acclimated seed. For this purpose, two digesters were used under similar starting conditions and operated for 235days with different mixing schemes. While both digesters exhibited a successful startup with comparable specific methane yield of 0.327 and 0.314l CH 4/gVS, continuous slow stirring improved stability by reducing average VFA accumulation from 2890 to 825mg HAc/l, propionate content from 2073 to 488mg/l, and VFA-to-alkalinity ratio from 0.32 to 0.07. As a result, the startup with slow mixing was faster and smoother accomplishing a higher loading capacity of 2.5gVS/l/d in comparison to 1.9gVS/l/d for non-mixing. Mixing equally improved microbial abundance from 6.6 to 10gVSS/l and enhanced solids and soluble COD removal. © 2012 Elsevier Ltd.

    The fermentation characteristics of six specific types of the organic fraction of municipal solid waste (OFMSW) were examined, with an emphasis on properties that are needed when designing plug-flow type anaerobic bioreactors. More specifically, the decomposition patterns of a vegetable (cabbage), fruits (banana and citrus peels), fresh leaf litter of bamboo and teak leaves, and paper (newsprint) waste streams as feedstocks were studied. Individual OFMSW components were placed into nylon mesh bags and subjected to various fermentation periods (solids retention time, SRT) within the inlet of a functioning plug-flow biogas fermentor. These were removed at periodic intervals, and their composition was analyzed to monitor decomposition rates and changes in chemical composition. Components like cabbage waste, banana peels, and orange peels fermented rapidly both in a plug-flow biogas reactor (PFBR) as well as under a biological methane potential (BMP) assay, while other OFMSW components (leaf litter from bamboo and teak leaves and newsprint) fermented slowly with poor process stability and moderate biodegradation. For fruit and vegetable wastes (FVW), a rapid and efficient removal of pectins is the main cause of rapid disintegration of these feedstocks, which left behind very little compost forming residues (2-5%). Teak and bamboo leaves and newsprint decomposed only to 25-50% in 30 d. These results confirm the potential for volatile fatty acids accumulation in a PFBR's inlet and suggest a modification of the inlet zone or operation of a PFBR with the above feedstocks

    The occurrence and removal of 42 pharmaceuticals, belonging to different therapeutic groups (analgesics and anti-inflammatory drugs, anti-ulcer agent, psychiatric drugs, antiepileptic drug, antibiotics, ss-blockers, diuretics, lipid regulator and cholesterol lowering statin drugs and anti-histamines), were studied in the wastewater and sewage sludge trains of a full scale integrated treatment plant. The plant employs a biological nutrient removal (BNR) process for the treatment of municipal wastewater, and a single-stage mesophilic anaerobic co-digestion for the treatment of wasted activated sludge mixed with the organic fraction of municipal solid waste (OFMSW), followed by a short-cut nitrification-denitrification of the anaerobic supernatant in a sequential batch reactor. Influent and effluent wastewater, as well as thickened, digested and treated sludge were sampled and analyzed for the selected pharmaceuticals in order to study their presence and fate during the treatment. Twenty three compounds were detected in influent and effluent wastewater and eleven in sludge. Infiltration of groundwater in the sewer system led to a dilution of raw sewage, resulting in lower concentrations in wastewater (up to 0.7 {mu}g/L in influent) and sludge (70 ng/g d.w.). Due to the dilution, overall risk quotient for the mixture of pharmaceuticals detected in effluent wastewater was less than one, indicating no direct risk for the aquatic environment. A wide range of removal efficiencies during the treatment was observed, i.e. < 20% to 90%. The influent concentrations of the target pharmaceuticals, as polar compounds, were undoubtedly mostly affected by BNR process in the wastewater train, and less by anaerobic-co-digestion. Mass balance calculations showed that less than 2% of the total mass load of the studied pharmaceuticals was removed by sorption. Experimentally estimated distribution coefficients (< 500 L/kg) also indicated that the selected pharmaceuticals preferably remain

    A pilot-scale study was undertaken to evaluate alternatives to the solid waste management of a Central American municipal market located in Estelí, Nicaragua. The municipal solid waste from the local market is the second largest contributor to the municipal solid waste (MSW) stream. Waste from the market without any previous sorting or treatment is open dumped. The options evaluated in this study were windrow composting, windrow composting with yard waste, bokashi and vermicompost. Significant differences between the properties of composts produced were found; however, all of them reduce the initial waste volume and are potential useful agronomic products for a survival agrarian milieu.

  10. Implementing Health-Promoting Leadership in Municipal Organizations: Managers’ Experiences with a Leadership Program

    Directory of Open Access Journals (Sweden)

    Robert Larsson

    2015-03-01

    Full Text Available The aim of this study was to analyze how line and middle managers experience and describe barriers and enablers in the implementation of a health-promoting leadership program in municipal organizations. A qualitative case study design was applied to examine the leadership program in a case involving implementation of an organizational health intervention. Data were mainly collected using semi-structured interviews with line and middle managers participating in the leadership program. Interviews with senior managers, notes from meetings/workshops, and written action plans were used as complementary data. The interview data were analyzed using a thematic analysis, and the complementary data using a summative content analysis. The findings show that the interviewed line and middle managers experienced this leadership program as a new approach in leadership training because it is based primarily on employee participation. Involvement and commitment of the employees was considered a crucial enabler in the implementation of the leadership program. Other enablers identified include action plans with specific goals, earlier experiences of organizational change, and integration of the program content into regular routines and structures. The line and middle managers described several barriers in the implementation process, and they described various organizational conditions, such as high workload, lack of senior management support, politically initiated projects, and organizational change, as challenges that limited the opportunities to be drivers of change. Taken together, these barriers interfered with the leadership program and its implementation. The study contributes to the understanding of how organizational-level health interventions are implemented in public sector workplaces.

  11. Understanding the security management practices of humanitarian organizations.

    Science.gov (United States)

    Bollettino, Vincenzo

    2008-06-01

    Humanitarian organisations operate in increasingly hostile environments. Although authoritative statistics are scarce, anecdotal evidence suggests that aid workers face life-threatening risks that are exacerbated by the growing number of humanitarian organisations operating in the field, the diversity of their mandates, the lack of common professional security standards, and limited success in inter-agency security coordination. Despite broad acceptance of the need for better security management and coordination, many humanitarian organisations remain ambivalent about devoting increased resources to security management and security coordination. A critical lack of basic empirical knowledge of the field security environment hampers efforts to enhance security management practices. The absence of a systematic means of sharing incident data undermines the capacity of the humanitarian community to address proactively security threats. In discussions about humanitarian staff safety and security, the least common denominator remains cumulative anecdotal evidence provided by the many security personnel working for humanitarian organisations in the feld.

    Graphical abstract: Display Omitted - Highlights: • A domestic scale prototype for the pre-treatment of OFMSW has been tested. • Two grinding techniques are compared and thermopress is used for the drying stage. • Increasing temperature up to 170 °C reduces energy consumption of the drying stage. • In the range 5–10 bar a reduction of 97% of the initial volume is obtained. • In most cases energy recovery from the dried waste matches energy consumption. - Abstract: In the present study a thermo-mechanical treatment for the disposal of the Organic Fraction of Municipal Solid Waste (OFMSW) at apartment or condominium scale is proposed. The process presents several advantages allowing to perform a significant volume and moisture reduction of the produced waste at domestic scale thus producing a material with an increased storability and improved characteristics (e.g. calorific value) that make it available for further alternative uses. The assessment of the applicability of the proposed waste pretreatment in a new scheme of waste management system requires several research steps involving different competences and application scales. In this context, a preliminary study is needed targeting to the evaluation and minimization of the energy consumption associated to the process. To this aim, in the present paper, two configurations of a domestic appliance prototype have been presented and the effect of some operating variables has been investigated in order to select the proper configuration and the best set of operating conditions capable to minimize the duration and the energy consumption of the process. The performances of the prototype have been also tested on three model mixtures representing a possible daily domestic waste and compared with an existing commercially available appliance. The results obtained show that a daily application of the process is feasible given the short treatment time required and the energy consumption comparable to the one of

  16. Spatial organization of the settlement network of the municipality of Čačak and tendencies of its development

    Directory of Open Access Journals (Sweden)

    Full Text Available The balanced and sustainable development of the functional area of Čačak is a precondition for greater integration of geospace. Based on the fact that settlements are the most striking elements of the cultural landscape and they are the holders of the functional organization and spatial transformation of geospace, there will be a special emphasis placed on the networking of these settlements and the analysis of its determinants. Both demographic and socioeconomic indicators were analyzed in order to determine the dominant spatial and functional processes occurring in the area that relate to the development of the municipality. Emphasis is placed on the changes in the type of population movement, functional transformation of the settlements, and changes in the level of social geographic transformation of settlements. Analysis of the demographic and socio-economic indicators showed that the settlement network of Čačak is, to a large extent, incoherent. Socio-geographic and functional transformation of settlements is articulated and directed entirely from the municipal center, and consequently the most affected settlements of periurban zone of Čačak and settlements along major roads. Adjusting to the modern development processes requires new spatial-functional relations at the municipality level in order to strengthen territorial cohesion and equal conditions of life.

  1. Challenges of information security incident learning: An industrial case study in a Chinese healthcare organization.

    Science.gov (United States)

    He, Ying; Johnson, Chris

    2017-12-01

    Security incidents can have negative impacts on healthcare organizations, and the security of medical records has become a primary concern of the public. However, previous studies showed that organizations had not effectively learned lessons from security incidents. Incident learning as an essential activity in the "follow-up" phase of security incident response lifecycle has long been addressed but not given enough attention. This paper conducted a case study in a healthcare organization in China to explore their current obstacles in the practice of incident learning. We interviewed both IT professionals and healthcare professionals. The results showed that the organization did not have a structured way to gather and redistribute incident knowledge. Incident response was ineffective in cycling incident knowledge back to inform security management. Incident reporting to multiple stakeholders faced a great challenge. In response to this case study, we suggest the security assurance modeling framework to address those obstacles.

    To identify the most and least commonly cited security management messages that nongovernmental organizations (NGOs) are communicating to their field staff, to determine the types of documentation that NGOs most often use to communicate key security messages, and to distinguish the points of commonality and divergence across organizations in the content of key security messages. The authors undertook a systematic review of available security policies, manuals, and training materials from 20 international humanitarian NGOs using the InterAction Minimum Operating Security Standards as the basis for a review framework. The most commonly cited standards include analytical security issues such as threat and risk assessment processes and guidance on acceptance, protection, and deterrence approaches. Among the least commonly cited standards were considering security threats to national staff during staffing decision processes, incorporating security awareness into job descriptions, and ensuring that national staff security issues are addressed in trainings. NGO staff receive security-related messages through multiple document types, but only 12 of the 20 organizations have a distinct security policy document. Points of convergence across organizations in the content of commonly cited standards were found in many areas, but differences in security risk and threat assessment guidance may undermine communication between aid workers about changes in local security environments. Although the humanitarian community has experienced significant progress in the development of practical staff security guidance during the past 10 years, gaps remain that can hinder efforts to garner needed resources, clarify security responsibilities, and ensure that the distinct needs of national staff are recognized and addressed.

  11. Composition variability of the organic fraction of municipal solid waste and effects on hydrogen and methane production potentials.

    Science.gov (United States)

    Alibardi, Luca; Cossu, Raffaello

    2015-02-01

    The composition of the Organic Fraction of Municipal Solid Waste (OFMSW) strongly depends on the place and time of collection for a specific municipality or area. Moreover synthetic food waste or organic waste from cafeterias and restaurants may not be representative of the overall OFMSW received at treatment facilities for source-separated waste. This work is aimed at evaluating the composition variability of OFMSW, the potential productions of hydrogen and methane from specific organic waste fractions typically present in MSW and the effects of waste composition on overall hydrogen and methane yields. The organic waste fractions considered in the study were: bread-pasta, vegetables, fruits, meat-fish-cheese and undersieve 20mm. Composition analyses were conducted on samples of OFMSW that were source segregated at household level. Batch tests for hydrogen and methane productions were carried out under mesophilic conditions on selected fractions and OFMSW samples. Results indicated that the highest production of hydrogen was achieved by the bread-pasta fraction while the lowest productions were measured for the meat-fish-cheese fraction. The results indicated that the content of these two fractions in organic waste had a direct influence on the hydrogen production potentials of OFMSW. The higher the content of bread-pasta fraction, the higher the hydrogen yields were while the contrary was observed for the meat-fish-cheese fraction. The definition of waste composition therefore represents fundamental information to be reported in scientific literature to allow data comparison. The variability of OFMSW and its effects on hydrogen potentials might also represents a problematic issue in the management of pilot or full-scale plants for the production of hydrogen by dark fermentation.

    2014-01-01

    Wastewater effluent samples were collected in the summer of 2009 from 16 different locations which included municipal and industrial wastewater treatment plants and petrochemical industrial outfalls in the Houston area. The effluent samples were analyzed for all 209 polychlorinated biphenyls (PCBs) congeners using high resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS) using the USEPA method 1668A. The total PCBs (∑ 209) concentration in the dissolved medium ranged from 1.01 to 8.12 ng/L and ranged from 2.03 to 31.2 ng/L in the suspended medium. Lighter PCB congeners exhibited highest concentrations in the dissolved phase whereas, in the suspended phase, heavier PCBs exhibited the highest concentrations. The PCB homolog concentrations were dominated by monochlorobiphenyls through hexachlorobiphenyls, with dichlorobiphenyls exhibiting the highest concentration amongst them at most of the effluent outfalls, in the suspended phase. Both total suspended solids (TSS) and various organic carbon fractions played an important role in the distribution of the suspended fractions of PCBs in the effluents. The log K oc values determined in the effluents suggest that effluent PCB loads might have more risk and impact than what standard partitioning models predict. - Highlights: • 209 PCB congeners were measured in 16 different municipal and industrial effluents. • PCB congener differences were elucidated for the various effluent types. • In addition to log K ow , organic carbon and TSS affect partitioning of PCBs. • High concentrations of homolog 2 maybe due to biotransformation of PCBs

    Wei, Chunhai

    2014-08-01

    The overall performance of a mesophilic anaerobic membrane bioreactor (AnMBR) for synthetic municipal wastewater treatment was investigated under a range of organic loading rate (OLR). A very steady and high chemical oxygen demand (COD) removal (around 98%) was achieved over a broad range of volumetric OLR of 0.8-10gCOD/L/d. The sustainable volumetric and sludge OLR satisfying a permeate COD below 50mg/L for general reuse was 6gCOD/L/d and 0.63gCOD/gMLVSS (mixed liquor volatile suspended solids)/d, respectively. At a high sludge OLR of over 0.6gCOD/gMLVSS/d, the AnMBR achieved high methane production of over 300ml/gCOD (even approaching the theoretical value of 382ml/gCOD). A low biomass production of 0.015-0.026gMLVSS/gCOD and a sustainable flux of 6L/m2/h were observed. The integration of a heat pump and forward osmosis into the mesophilic AnMBR process would be a promising way for net energy recovery from typical municipal wastewater in a temperate area. © 2014 Elsevier Ltd.

    2001-01-01

    This project includes preliminary investigations about anaerobic degradation of organic municipal waste together with liquid manure. Investigations consist of characterization of organic municipal waste and preliminary test of anaerobic degradation of the waste. Characterization is related especially to the contents of environmentally hazardous substances, while the degradation process is characterized by means of determination of biogas potential in batch test and methane yield, organic VS (volatile solids) reduction and process stability in reactor test. In relation to environmentally hazardous substances the content of NPE and LAS in all tests of organic municipal waste was insignificant. The main problem was the content of DEHP, concentration of which is half of the cut-off value in the municipal waste. By TS (Total solid) reduction through the biogas process the DEHP concentration will thus exceed the cut-off value pr kg TS in the effluent if DEHP is not removed at the same time. The PAH concentration in the collected waste was only in one case at the level of the cut-off value which would exceed the cut-off value if no removal happens through the anaerobic degradation. The biogas potential of municipal waste was determined to be 187 m{sup 3}biogas/m{sup 3}waste, which makes organic municipal waste a very attractive waste type for biogas plants. No direct restraint by degradation of clean waste in batch test could be demonstrated. In the reactor test a stable degradation of organic municipal waste with an increasing supply of waste in mixture with manure could be established. By treatment of a mixture of municipal waste and manure in ratio to 50 : 50 a methane yield on 350 lCH{sub 4} kg VS and a VS-reduction between 50% and 60% could be obtained. Using clean municipal waste diluted with water the methane yield was higher than in the batch test and a VS reduction of up to 80% could be obtained. The analyses of DEHP and PAH in influent and effluent of the

  18. Characteristics and Biodegradability of Wastewater Organic Matter in Municipal Wastewater Treatment Plants Collecting Domestic Wastewater and Industrial Discharge

    Full Text Available Municipal wastewater treatment plants (WWTPs in Korea collect and treat not only domestic wastewater, but also discharge from industrial complexes. However, some industrial discharges contain a large amount of non-biodegradable organic matter, which cannot be treated properly in a conventional biological WWTP. This study aimed to investigate the characteristics and biodegradability of the wastewater organic matter contained in the industrial discharges and to examine the fate of the industrial discharges in a biological WWTP. In contrast to most previous studies targeting a specific group of organic compounds or traditional water quality indices, such as biological oxygen demand (BOD and chemical oxygen demand (COD, this study was purposed to quantify and characterize the biodegradable and nonbiodegradable fractions of the wastewater organic matter. Chemical oxygen demand (COD fractionation tests and fluorescence spectroscopy revealed that the industrial discharge from dyeing or pulp mill factories contained more non-biodegradable soluble organic matter than did the domestic wastewater. Statistical analysis on the WWTPs’ monitoring data indicated that the industrial discharge containing non-biodegradable soluble organic matter was not treated effectively in a biological WWTP, but was escaping from the system. Thus, industrial discharge that contained non-biodegradable soluble organic matter was a major factor in the decrease in biodegradability of the discharge, affecting the ultimate fate of wastewater organic matter in a biological WWTP. Further application of COD fractionation and fluorescence spectroscopy to wastewaters, with various industrial discharges, will help scientists and engineers to better design and operate a biological WWTP, by understanding the fate of wastewater organic matter.

  19. Oxygen demand for the stabilization of the organic fraction of municipal solid waste in passively aerated bioreactors

    International Nuclear Information System (INIS)

    Kasinski, Slawomir; Wojnowska-Baryla, Irena

    2014-01-01

    Highlights: • The use of an passively aerated reactor enables effective stabilization of OFMSW. • Convective air flow does not inhibit the aerobic stabilization of waste. • The use of an passively aerated reactor reduces the heat loss due to convection. • The volume of supplied air exceeds 1.7–2.88 times the microorganisms demand. - Abstract: Conventional aerobic waste treatment technologies require the use of aeration devices that actively transport air through the stabilized waste mass, which greatly increases operating costs. In addition, improperly operated active aeration systems, may have the adverse effect of cooling the stabilized biomass. Because active aeration can be a limiting factor for the stabilization process, passive aeration can be equally effective and less expensive. Unfortunately, there are few reports documenting the use of passive aeration systems in municipal waste stabilization. There have been doubts raised as to whether a passive aeration system provides enough oxygen to the organic matter mineralization processes. In this paper, the effectiveness of aeration during aerobic stabilization of four different organic fractions of municipal waste in a reactor with an integrated passive ventilation system and leachate recirculation was analyzed. For the study, four fractions separated by a rotary screen were chosen. Despite the high temperatures in the reactor, the air flow rate was below 0.016 m 3 /h. Using Darcy’s equation, theoretical values of the air flow rate were estimated, depending on the intensity of microbial metabolism and the amount of oxygen required for the oxidation of organic compounds. Calculations showed that the volume of supplied air exceeded the microorganisms demand for oxidation and endogenous activity by 1.7–2.88-fold

    Effluent organic matter (EfOM) from municipal wastewater treatment plants potentially has a detrimental effect on both aquatic organisms and humans. This study evaluated the removal and transformation of chromophoric dissolved organic matter (CDOM) and fluorescent dissolved organic matter (FDOM) in a full-scale wastewater treatment plant under different seasons. The results showed that bio-treatment was found to be more efficient in removing bulk DOM (in term of dissolved organic carbon, DOC) than CDOM and FDOM, which was contrary to the disinfection process. CDOM and FDOM were selectively removed at various stages during the treatment. Typically, the low molecular weight fractions of CDOM and protein-like FDOM were more efficiently removed during bio-treatment process, whereas the humic-like FDOM exhibited comparable decreases in both bio-treatment and disinfection processes. Overall, the performance of the WWTP was weak in terms of CDOM and FDOM removal, resulting in enrichment of CDOM and FDOM in effluent. Moreover, the total removal of the bulk DOM (PCDOM and the humic-like FDOM showed little differences between summer and winter. In all, the results provide useful information for understanding the fate and transformation of DOM, illustrating that sub-fractions of DOM could be selectively removed depending on treatment processes and seasonality.

    The purpose of this work is to study the characteristics of the co-composting of municipal solid waste (MSW), sewage sludge, grass and sawdust. Differing proportions of biodegradable waste were investigated through changes of temperature, oxygen consumption, organic matters, moisture content, carbon, nitrogen, C/N ratio as well as heavy metals and pathogen microorganisms content. The present study has shown that addition of MSW above 10% had a negative impact on the composting process. The initial C/N of the mixtures with a higher MSW content was below 18. Lower losses of organic matter occurred during composting for the mixture with the highest addition of MSW. Although studies have shown that composting is a good method for the disposal of organic waste additional research is required in order to optimize the organic and nitrogen compounds degradation during the co-composting process. In conclusion, a 1:4:4:1 mixture of MSW:sewage sludge:grass:sawdust is recommended because it can achieve high temperature as well as the highest organic matter degradation and highest N content in the final composting product. The concentration of heavy and light metals in all composts was within the limits of regulation of the Polish Minister of Agriculture and Rural Development.

    The study was carried out on the basis of clinic “Medicine” in 2014-2015 concerning security culture. The sampling included 465 filled HSPSC questionnaires. The comparative analysis of received was implemented. The “Zubovskaia district hospital” Having no accreditation according security standards and group of clinics from USA functioning for many years in the system of patient security support were selected as objects for comparison. The evaluation was implemented concerning dynamics of security culture in organization at implementation of strategies of security of patients during 5 years and comparison of obtained results with USA clinics was made. The study results demonstrated that in conditions of absence of implemented standards of security in medical organization total evaluation of security remains extremely low. The study of security culture using HSPSC questionnaire is an effective tool for evaluating implementation of various strategies of security ofpatient. The functioning in the system of international standards of quality, primarily JCI standards, permits during several years to achieve high indices of security culture.

    The Danish company Solum A/S has developed a two-stage dry anaerobic digestion process labelled AIKAN® for the biological conversion of the organic fraction of municipal solid waste (OFMSW) into biogas and compost. In the AIKAN® process design the methanogenic (2nd) stage is separated from...... the hydrolytic (1st) stage, which enables pump-free feeding of the waste into the 1st stage (processing module), and eliminates the risk for blocking of pumps and pipes by pumping only the percolate from the 1st stage into the 2nd stage (biogas reactor tank). The biogas yield of the AIKAN® two-stage process......, however, has shown to be only about 60% of the theoretical maximum. Previous monitoring of the hydrolytic and methanogenic activity in the two stages of the process revealed that the bottleneck of the whole degradation process is rather found in the hydrolytic first stage while the methanogenic second...

    Three operational strategies to reduce inhibition due to ammonia during thermophilic anaerobic digestion of source-sorted organic fraction of municipal solid waste (SS-OFMSW) rich in proteins were investigated. Feed was prepared by diluting SS-OFMSW (ratio of 1:4) with tap water or reactor process...... ammonium bicarbonate additions. Dilution of SS-OFMSW with fresh water showed a stable performance with volatile fatty acids of solids (VS). Use of recirculated process water after stripping ammonia showed even better performance with a methane yield...... of 0.43 m(3) kg(-1)VS. Recirculation of process water alone on the other hand, resulted in process inhibition at both TAN levels of 3.5 and 5.5 g-N l(-1). However, after a short period, the process recovered and adapted to the tested TAN levels. Thus, use of recirculated process water after stripping...

    Full Text Available The aim of this work is focused on research of information security in organizations, with a focus on cybersecurity. In accordance with the theoretical analysis, the subject of the empirical part of the work is the analysis of information security in Serbia, in order to better understand the information security programs and management structures in organizations in Serbia. The survey covers a variety of industries and discusses how organizations assess, develop, create and support their programs to ensure information security. The survey included 53 companies. The results that were obtained enabled us to select five core elements of the program on the state of information security and cybersecurity in Serbian companies: most companies had not been exposed to cybersecurity incidents; in most companies policy, procedures and spheres of responsibility for information security exist, there are not enough controls to ensure compliance with relevant safety standards by third parties, top management and end-users are insufficiently familiar with cybersecurity risks, although they apply basic measures of protection, safety protection systems are very rare. The scientific goal of this work is to, on the basis of the results obtained, make conclusions that can contribute to the study of corporate information security with special emphasis on cybersecurity. The practical aim of the research is the application of the results for more efficient implementation process of security against cyber attacks in the Serbian organizations.

  3. Energy Recovery from the Organic Fraction of Municipal Solid Waste: A Real Options-Based Facility Assessment

    Directory of Open Access Journals (Sweden)

    Luigi Ranieri

    2018-01-01

    Full Text Available During the last years, due to the strict regulations on waste landfilling, anaerobic digestion (AD of the organic fraction of municipal solid waste (OFMSW is increasingly considered a sustainable alternative for waste stabilization and energy recovery. AD can reduce the volume of OFMSW going to landfill and produce, at the same time, biogas and compost, all at a profit. The uncertainty about the collected quantity of organic fraction, however, may undermine the economic-financial sustainability of such plants. While the flexibility characterizing some AD technologies may prove very valuable in uncertain contexts since it allows adapting plant capacity to changing environments, the investment required for building flexible systems is generally higher than the investment for dedicated equipment. Hence, an adequate justification of investments in these flexible systems is needed. This paper presents the results of a study aimed at investigating how different technologies may perform from technical, economic and financial standpoints, in presence of an uncertain organic fraction quantity to be treated. Focusing on two AD treatment plant configurations characterized by a technological process with different degree of flexibility, a real options-based model is developed and then applied to the case of the urban waste management system of the Metropolitan Area of Bari (Italy. Results show the importance of pricing the flexibility of treatment plants, which becomes a critical factor in presence of an uncertain organic fraction. Hence, it has to be taken into consideration in the design phase of these plants.

    Wastewater effluent samples were collected in the summer of 2009 from 16 different locations which included municipal and industrial wastewater treatment plants and petrochemical industrial outfalls in the Houston area. The effluent samples were analyzed for all 209 polychlorinated biphenyls (PCBs) congeners using high resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS) using the USEPA method 1668A. The total PCBs (∑ 209) concentration in the dissolved medium ranged from 1.01 to 8.12 ng/L and ranged from 2.03 to 31.2 ng/L in the suspended medium. Lighter PCB congeners exhibited highest concentrations in the dissolved phase whereas, in the suspended phase, heavier PCBs exhibited the highest concentrations. The PCB homolog concentrations were dominated by monochlorobiphenyls through hexachlorobiphenyls, with dichlorobiphenyls exhibiting the highest concentration amongst them at most of the effluent outfalls, in the suspended phase. Both total suspended solids (TSS) and various organic carbon fractions played an important role in the distribution of the suspended fractions of PCBs in the effluents. The log K{sub oc} values determined in the effluents suggest that effluent PCB loads might have more risk and impact than what standard partitioning models predict. - Highlights: • 209 PCB congeners were measured in 16 different municipal and industrial effluents. • PCB congener differences were elucidated for the various effluent types. • In addition to log K{sub ow}, organic carbon and TSS affect partitioning of PCBs. • High concentrations of homolog 2 maybe due to biotransformation of PCBs.

  5. Health promotion at local level: a case study of content, organization and development in four Swedish municipalities

    Full Text Available Abstract Background Several health determinants are related to local conditions and prerequisites at community level. For this reason, strengthening community action has been one of five strategies implemented in health promotion since the end of the 1980s. Such action includes setting priorities, making decisions, planning strategies, and implementing them to achieve better health. The aim of this paper is to obtain a deeper understanding of content, organization and processes in the development of local health promotion. Methods A qualitative multiple case study of four Swedish municipalities. The cases were analyzed in accordance with the principles of cross-case study analysis, and a content analysis of documents and interviews was conducted in two steps. First, a manifest content analysis was performed to identify present and former actors and measures. Thereafter, a latent content analysis was performed to investigate structures and processes in local contexts. Results The results of the inductive content analysis showed development of local health promotion in three phases: initiation, action, and achievement. Strengthening factors were local actors, health statistics and events. Hindering factors were lack of resources and vague objectives. External factors, e.g. national policies, were not perceived as prominent influencing factors. Media reports were regarded as having had an influence, but only to some extent. The content of local health promotion has developed from ad-hoc lifestyle and behaviour-related actions into structural, intersectoral actions related to determinants of health. Conclusions The municipalities have organized and developed their health promotion targets, actions and priorities on the basis of local needs and prerequisites. The three phases in the identified health promotion processes were experienced and documented as being subject to greater influence from internal rather than external strengthening and hindering

    2018-03-01

    Many cities in developing countries is facing a serious problems to dealing with huge municipal solid waste (MSW) generated. The main approach to manage MSW is causes environmental impact associated with the leachate and landfill gas emissions. On the other hand, the energy available also limited by rapid growth of population and economic development due to shortage of the natural resource. In this study, the potential utilized of MSW to produce refuse derived fuel (RDF) was investigate. The RDF was produced with various organic waste content. Then, the RDF was subjected to laboratory analysis to determine its characteristic including the calorific value. The results shows the moisture content was increased by increasing organic waste content, while the calorific value was found 17-36 MJ/kg. The highest calorific value was about 36 MJ/kg obtained at RDF with 40% organic waste content. This results indicated that the RDF can be use to substitute coal in main burning process and calcinations of cement industry.

    The characteristics of dissolved organic matter (DOM) and the biotoxicity of these components were investigated in a municipal wastewater reclamation reverse osmosis (mWRRO) system with a microfiltration (MF) pretreatment unit. The MF pretreatment step had little effect on the levels of dissolved organic carbon (DOC) in the secondary effluent, but the addition of chlorine before MF promoted the formation of organics with anti-estrogenic activity. The distribution of excitation emission matrix (EEM) fluorescence constituents exhibited obvious discrepancies between the secondary effluent and the reverse osmosis (RO) concentrate. Using size exclusion chromatography, DOM with low molecular weights of approximately 1.2 and 0.98 kDa was newly formed during the mWRRO. The normalized genotoxicity and anti-estrogenic activity of the RO concentrate were 32.1 ± 10.2 μg4-NQO/mgDOC and 0.36 ± 0.08 mgTAM/mgDOC, respectively, and these values were clearly higher than those of the secondary effluent and MF permeate. The florescence volume of Regions I and II in the EEM spectrum could be suggested as a surrogate for assessing the genotoxicity and anti-estrogenic activity of the RO concentrate.

    MDSplus has become a real standard de facto data access method in the fusion community. Based on this, it was a priority for EFDA-Federation to integrate this technology as a new service for federated users, providing secure access mechanisms to MDSplus compatible applications. To achieve this, it has been necessary to upgrade MDSplus and make it compatible with PAPI technology, which is currently used as security infrastructure in the EFDA-Federation. Additionally, the included modifications are useful for future integrations in other federation technologies such as Shibboleth. The integration of MDSplus into a federated structure has several benefits. From the service management point of view, there is a simplification of the installation of new MDSplus services in fusion community and its corresponding security management. From the user point of view, the integration of MDSplus into a federated structure has several advantages. The first one is user mobility, which is the possibility of accessing data independently of his client IP address. The second one is a multi-organisation infrastructure, so the user can access data from different organisations that implement MDSplus interface. Finally, single sign on PAPI feature enables users to access to different MDSplus data sources, and other federated services, with just one authentication. This document is composed of a poster and its abstract. (authors)

    Lindmark, Johan; Eriksson, Per; Thorin, Eva

    2014-01-01

    Highlights: • Effects of mixing on the anaerobic digestion of municipal solid waste. • Digestion of fresh substrate and post-digestion at three mixing intensities were evaluated. • Mixing performed at 150 RPM, 25 RPM and minimally intermittently. • Increased biogas production rates and yields at lower mixing intensities. - Abstract: Mixing inside an anaerobic digester is often continuous and is not actively controlled. The selected mixing regime can however affect both gas production and the energy efficiency of the biogas plant. This study aims to evaluate these effects and compare three different mixing regimes, 150 RPM and 25 RPM continuous mixing and minimally intermittent mixing for both digestion of fresh substrate and post-digestion of the organic fraction of municipal solid waste. The results show that a lower mixing intensity leads to a higher biogas production rate and higher total biogas production in both cases. 25 RPM continuous mixing and minimally intermittent mixing resulted in similar biogas production after process stabilization, while 150 RPM continuous mixing resulted in lower production throughout the experiment. The lower gas production at 150 RPM could not be explained by the inhibition of volatile fatty acids. Cumulative biogas production until day 31 was 295 ± 2.9, 317 ± 1.9 and 304 ± 2.8 N ml/g VS added during digestion of fresh feed and 113 ± 1.3, 134 ± 1.1 and 130 ± 2.3 N ml/g VS added during post digestion for the 150 RPM, 25 RPM and minimally mixed intensities respectively. As well as increasing gas production, optimal mixing can improve the energy efficiency of the anaerobic digestion process

    To describe how registered nurses (RNs) perceive delegation to unlicensed personnel (UP) in a municipal healthcare context in Sweden. Within municipal health care RNs often delegate tasks to UP. The latter have practical training, but lack formal competence. Twelve RNs were interviewed and the material was analysed using a phenomenographic approach. Owing to a shortage of RNs, delegation is seen as a prerequisite for a functioning organization. This necessity also involves a number of perceived contradictions in three areas: (1) the work situation of RNs - facilitation and relief vs. lack of control, powerlessness, vagueness regarding responsibility, and resignation; (2) the relationship with unlicensed personnel - stimulation, possibility for mentoring, use of UP competence and the creation of fairness vs. questioning UP competence; and (3) The patients - increase in continuity, quicker treatment, and increased security vs. insecurity (with respect to, for example, the handling of medicine). Registered nurses perceptions of delegation within municipal healthcare involve their own work situation, the UP and the patients. Registered nurses who delegate to UP must be given time for mentoring such that the nursing care is safe care of high quality. © 2011 The Authors.

In this study semi dry anaerobic digestion of organic solid wastes was conducted for 45 days in a lab-scale batch experiment for total solid concentration of 100 g/L for investigating the start-up performances under thermophilic condition (50 °C). The performance of the reactor was evaluated by measuring the daily biogas production and calculating the degradation of total solids and the total volatile solids. The biogas yield at the end of the digestion was 52.9 L/kg VS (volatile solid) for the total solid (TS) concentration of 100 g/L. About 66.7% of the volatile solid degradation was obtained during the digestion. A first order model based on the availability of substrate as the limiting factor was used to perform the kinetic studies of batch anaerobic digestion system. The value of reaction rate constant, k, obtained was 0.0249 day −1

    Two laboratory scale anaerobic digestion systems for hydrogen production from organic fraction of municipal solid waste (OFMSW) and synthetic wastewater were compared in this study. One of them was formed by a coupled packed bed reactor (PBR) containing 19.4 L of OFMSW and the other an upflow anaerobic sludge bed (UASB) of 3.85 L. The reactors were inoculated with a mixture of non-anaerobic inocula. In the UASB the percentage of hydrogen yield reached 51% v/v and 127NmLH{sub 2}/gvs removed with a hydraulic retention time (HRT) of 24 h. The concentration of synthetic wastewater in the affluent was 7 g COD/L. For the PBR the percentage yield was 47% v/v and 99NmLH{sub 2}/gvs removed with a mass retention time (MRT) of 50 days and the organic load rate of 16 gvs (Grams Volatile Solids)/(kg-day). The UASB and PBR systems presented maximum hydrogen yields of 30% and 23%, respectively, which correspond to 4molH{sub 2}/mol glucose. These values are similar to those reported in the literature for the hydrogen yield (37%) in mesophilic range. The acetic and butyric acids were present in the effluent as by-products in watery phase. In this work we used non-anaerobic inocula made up of microorganism consortium unlike other works where pure inocula or that from anaerobic sludge was used. (author)

    Biologically-treated municipal solid waste (MSW) leachate still contains many kinds of bio-recalcitrant organic matter. A new plate and frame electrochemical reactor was designed to treat these materials under flow conditions. In the electrochemical oxidation process, NH3 and color could be easily removed by means of electro-generated chlorine/hypochlorite within 20 min. The effects of major process parameters on the removal of organic pollutants were investigated systematically. Under experimental conditions, the optimum operation parameters were current density of 65 mA/cm2, flow velocity of 2.6 cm/sec in electrode gap, and initial chloride ion concentration of 5000 mg/L. The COD in the leachate could be reduced below 100 mg/L after 1 hr of treatment. The kinetics and mechanism of COD removal were investigated by simultaneously monitoring the COD change and chlorine/hypochlorite production. The kinetics of COD removal exhibited a two-stage kinetic model, and the decrease of electro-generated chlorine/hypochlorite production was the major mechanism for the slowing down of the COD removal rate in the second stage. The narrowing of the electrode gap is beneficial for COD removal and energy consumption.

    Bairiot, X.

    2016-01-01

    During more than 40 years of transport of radioactive materials, Transnubel noticed the evolution regarding Safety and Security requirements. These requirements have to be met within the frame of commercial activities, with constraints as planning, cost control, availabilities, .... In addition, other requirements issued by customers, eventually linked with Safety and Security, have also to be taken in account. Since many years, the company is therefore organized for all daily activities on basis of a Quality System: this Quality System, based on the ISO 9000, aims to give an answer to the ISO 9000 requirements, but also to the safety requirements, which are integrated at different levels in the Quality System. The trend of the last years concerning Security has an impact on the organization and documentation in the company. Due to the legal requirements, the implementation has not been possible within the same ISO 9000 structure. As a result, a Security system as been created on a similar basis as the ISO 9000: security manual, security procedures and security working instructions. Two systems therefore are existing within our company: a Quality System including Safety, and a Security System. In the frame of our international transports, we need to rely on the flexibility of our Quality System and Security System to allow us to take in account national regulations: the regulations dealing with Security and Safety (and their interpretations) are national competences, and differ once borders are crossed. The presentation will give an overview of the implementation of the Safety and Security aspects in the company: the structure and the implementation. And will try to answer the question: is the increase of the structure / documents always a benefit to the execution of the transports? (author)

  5. Hacking a Bridge: An Exploratory Study of Compliance-Based Information Security Management in Banking Organization

    Directory of Open Access Journals (Sweden)

    Tesleem Fagade

    2017-10-01

    Full Text Available This work is approached through the lens of compliant security by drawing on the concepts of neutralization theory, a prominent postulation in the criminology domain and the 'big five' personality construct. This research is conducted based on a case study of ISO/IEC27001 Standard certified banks, to empirically evaluate the link between cybersecurity protocols violation and how employees rationalise security behaviour. We propose that compliance-based security has the propensity for a heightened sense of false security and vulnerability perception; by showing that systemic security violation in compliance-based security models can be explained by the level of linkages from the personality construct and the neutralization theory. Building on the survey responses from banking organization employees and the application of partial least square structural equation modelling (PLS-SME analysis to test the hypotheses and validate survey samples, we draw a strong inference to support the importance of individual security scenario effect as a vital complementary element of compliance-based security. Based on our initial findings, conceptual principles and practical guidelines for reducing insider threats and improving employees' compliance is presented. We then suggest how information security protocol violations can be addressed in that context.

    Understanding the heterogeneous evolution characteristics of dissolved organic matter fractions derived from compost is crucial to exploring the composting biodegradation process and the possible applications of compost products. Herein, two-dimensional correlation spectroscopy integrated with reversed-phase high performance liquid chromatography and size exclusion chromatography were utilized to obtain the molecular weight (MW) and polarity evolution characteristics of humic acid (HA), fulvic acid (FA), and the hydrophilic (HyI) fractions during composting. The high-MW humic substances and building blocks in the HA fraction degraded faster during composting than polymers, proteins, and organic colloids. Similarly, the low MW acid FA factions transformed faster than the low weight neutral fractions, followed by building blocks, and finally polymers, proteins, and organic colloids. The evolutions of HyI fractions during composting occurred first for building blocks, followed by low MW acids, and finally low weight neutrals. With the progress of composting, the hydrophobic properties of the HA and FA fractions were enhanced. The degradation/humification process of the hydrophilic and transphilic components was faster than that of the hydrophobic component. Compared with the FA and HyI fractions, the HA fraction exhibited a higher MW and increased hydrophobicity. Copyright © 2018 Elsevier B.V. All rights reserved.

    Reverse osmosis (RO) concentrate from municipal wastewater reclamation reverse osmosis (mWRRO) system containing organic compounds may associate with toxic risk, and its discharge might pose an environmental risk. To identify a basis for the selection of feasible technology in treating RO concentrates, the characteristics and biotoxicity of different fractions of dissolved organic matter (DOM) in RO concentrates from an mWRRO system were investigated. The results indicated that the hydrophilic neutrals (HIN), hydrophobic acids (HOA) and hydrophobic bases (HOB) accounted for 96% of the dissolved organic carbon (DOC) of the total DOM in the RO concentrate. According to the SEC chromatograph detected at 254 nm wavelength of UV, the DOM with molecular weight (MW) 1-3 kDa accounted for the majority of the basic and neutral fractions. The fluorescence spectra of the excitation emission matrix (EEM) indicated that most aromatic proteins, humic/fulvic acid-like and soluble microbial by-product-like substances existed in the fractions HOA and hydrophobic neutrals (HON). The genotoxicity and anti-estrogenic activity of the RO concentrate were 1795.6 ± 57.2 μg 4-NQOL(-1) and 2.19 ± 0.05 mg TAM L(-1), respectively. The HIN, HOA, and HOB contributed to the genotoxicity of the RO concentrate, and the HIN was with the highest genotoxic level of 1007.9 ± 94.8 μg 4-NQOL(-1). The HOA, HON, and HIN lead to the total anti-estrogenic activity of the RO concentrate, and HOA occupied approximately 60% of the total, which was 1.3 ± 0.17 mg TAM L(-1).

    This paper investigates the organic pollution status of shallow aquifer sediments and groundwater around Zhoukou landfill. Chlorinated aliphatic hydrocarbons, monocylic aromatic hydrocarbons, halogenated aromatic hydrocarbons, organochlorine pesticides and other pesticides, and polycyclic aromatic hydrocarbons (PAHs) have been detected in some water samples. Among the detected eleven PAHs, phenanthrene, fluorine, and fluoranthene are the three dominant in most of the groundwater samples. Analysis of groundwater samples around the landfill revealed concentrations of PAHs ranging from not detected to 2.19 μg/L. The results show that sediments below the waste dump were low in pollution, and the shallow aquifer, at a depth of 18-30 m, was heavily contaminated, particularly during the wet season. An oval-shaped pollution halo has formed, spanning 3 km from west to east and 2 km from south to north, and mainly occurs in groundwater depths of 2-4 m. For PAH source identification, both diagnostic ratios of selected PAHs and principal component analysis were studied, suggesting mixed sources of pyro- and petrogenic derived PAHs in the Zhoukou landfill. Groundwater table fluctuations play an important role in the distribution of organic pollutants within the shallow aquifer. A conceptual model of leachate migration in the Quaternary aquifers surrounding the Zhoukou landfill has been developed to describe the contamination processes based on the major contaminant (PAHs). The groundwater zone contaminated by leachate has been identified surrounding the landfill.

    Co-digestion and pre-treatment have been recognized as effective, low-cost and commercially viable approaches to reduce anaerobic digestion process limitations and improve biogas yields. In our previous batch-scale study, fat, oil, and grease (FOG) was investigated as a suitable potential co-substrate, and thermo-chemical pre-treatment (TCPT) at pH = 10 and 55 °C improved CH4 production from FOG co-digestions. In this project, co-digestions with FOG were studied in bench-scale two-stage thermophilic semi-continuous flow co-digesters with suitable TCPT (pH = 10, 55 °C). Overall, a 25.14 ± 2.14 L/d (70.2 ± 1.4% CH4) biogas production was obtained, which was higher than in the two-stage system without pre-treatment. The results could provide valuable fundamental information to support full-scale investigations of anaerobic co-digestion of municipal organic wastes.

    In order to harvest high-efficient hydrogen producing seeds, five pretreatment methods (including acid, heat, sonication, aeration and freeze/thawing) were performed on anaerobic digested sludge (AS) which was collected from a batch anaerobic reactor for treating organic fraction of municipal solid waste. The hydrogen production tests were conducted in serum bottles containing 20 gVS/L (24.8 g COD/L) mixture of rice and lettuce powder at 37 C. The experimental results showed that the heat and acid pretreatment completely repressed the methanogenic activity of AS, but acid pretreatment also partially repressed hydrogen production. Sonication, freeze/thawing and aeration did not completely suppress the methanogen activity. The highest hydrogen yields were 119.7, 42.2, 26.0, 23.0, 22.7 and 22.1 mL/gVS for heated, acidified, freeze/thawed, aerated, sonicated and control AS respectively. A pH of about 4.9 was detected at the end of hydrogen producing fermentation for all tests. The selection of an initial pH can markedly affect the hydrogen producing ability for heated and acidified AS. The higher initial pH generated higher hydrogen yield and the highest hydrogen yield was obtained with initial pH 8.9 for heated AS. (author)

    This paper evaluated a novel pilot scale hybrid treatment system which combines rotating hanging media bioreactor (RHMBR), submerged membrane bioreactor (SMBR) along with electrocoagulation (EC) as post treatment to treat organic and nutrient pollutants from municipal wastewater. The results indicated that the highest removal efficiency was achieved at the internal recycling ratio as 400% of the influent flow rate which produced a superior effluent quality with 0.26mgBOD5L(-1), 11.46mgCODCrL(-1), 0.00mgNH4(+)-NL(-1), and 3.81mgT-NL(-1), 0.03mgT-PL(-1). During 16months of operation, NH4(+)-N was completely eliminated and T-P removal efficiency was also up to 100%. It was found that increasing in internal recycling ratio could improve the nitrate and nitrogen removal efficiencies. Moreover, the TSS and coliform bacteria concentration after treatment was less than 5mgL(-1) and 30MPNmL(-1), respectively, regardless of internal recycling ratios and its influent concentration.

    Compost capability of restoring or enhancing soil quality depends on several parameters, such as soil characteristics, compost carbon, nitrogen and other nutrient content, heavy metal occurrence, stability and maturity. This study investigated the possibility of relating compost stability and maturity to water-extractable organic matter (WEOM) properties and amendment effect on soil quality. Three composts from municipal sewage sludge and rice husk (AN, from anaerobic wastewater treatment plants; AE, from aerobic ones; MIX, from both anaerobic and aerobic ones) have been analysed and compared to a traditional green waste compost (GM, from green manure, solid waste and urban sewage sludge). To this aim, WEOMs were characterized through chemical analysis; furthermore, compost stability was evaluated through oxygen uptake rate calculation and maturity was estimated through germination index determination, whereas compost impact on soil fertility was studied, in a lab-scale experiment, through indicators as inorganic nitrogen release, soil microbial biomass carbon, basal respiration rate and fluorescein di-acetate hydrolysis. The obtained results indicated that WEOM characterization could be useful to investigate compost stability (which is related to protein and phenol concentrations) and maturity (related to nitrate/ammonium ratio and degree of aromaticity) and then compost impact on soil functionality. Indeed, compost stability resulted inversely related to soil microbial biomass, basal respiration rate and fluorescein di-acetate hydrolysis when the products were applied to the soil.

    The Paris and Vienna Conventions internationally agreeded that health care and hospitalization guarantee and disability pension or death due to victim's outside the nuclear installations, as well as the organization funds contributions should be fixed by the internal rights of each Signatory Part. The present study, applicable to nine countries (Germany, Belgium, Brazil, France, Italy, Low Countries, United Kingdom, Sweden and Switzerland) sets up that the social security levels are more or less high and that the charges contributions could be important in countries under subrogation, even reduced or null in countries under imputation. In cases of transfrontier accidents, the contributions extension relies on harmonized rights with the social security organizations of victim's countries. Each indenominity victim's dossier could take a long time. The study concludes that the regulatory services of the social security organizations and their responsible operators or substitutes insurers should coordinate their interventions by using the information system

    Wastewater treatment plants produce large amounts of biosolids that can be utilized for land applications. However, prior to their use, these biosolids must be treated to eliminate risks of infections and to reduce upsetting odors. In this study, microbiological and chemical analyzes were performed before and after treatment of sewage sludge with 3 MeV of an electron beam accelerator in a pilot processing plant. Thus, we determined that dose 4.5 kGy was required to reduce fecal coliform counts to safe levels for land applications of sludge while, 14.5 kGy was necessary to decrease Ascaris ova counts to safe levels. Furthermore, at low doses, electron beam irradiation showed little effect on the concentrations of volatile organic compounds, while some increase were recorded at high doses. The concentration of dimethyl sulfide was reduced by 50–70% at irradiation doses of 25.7 kGy and 30.7 kGy respectively. By contrast, electron beam irradiation increased dimethyl disulfide concentrations. We also showed that electron beam treatment was less energy-consuming with shorter processing times than conventional techniques used to decontaminate sludge. Hence opening new avenues for large urban agglomerations to save money and time when treating biosolids for land application. - Highlights: • Use of electron beam irradiation for the treatment of municipal sewage sludge. • Irradiation at 4.5 kGy is required to eliminate risks of bacterial infection. • Irradiation at 14.5 kGy is required to eliminate risks of helminth infection. • Electron beam technology is not effective for controlling volatile organic compounds. • Electron beam treatment of sludge is less expensive than traditional techniques

    In this work the effects of selected types of biomass ash on the composting process and final product quality were studied by conducting a 96-day long experiment where the source separated organic fraction of municipal waste, mixed with wood prunings that served as bulking agent, was added with 0%, 2%, 4% and 8% wt/wt of biomass ash. The evolution over time of the main process parameters was observed, and the final composts were characterised. On the basis of the results, both the composting process and the quality of the final product were improved by ash addition. Enhanced volatile solids reduction and biological stability (up to 32% and 52%, respectively, as compared to the unamended product) were attained when ash was added, since ash favored the aerobic degradation by acting asa physical conditioner. In the final products, higher humification of organic matter (expressed in terms of the humification index, that was 2.25 times higher in the most-enriched compost than in the unamended one) and total Ca, K, Mg and P content were observed when ash was used. The latter aspect may influence the composts marketability positively, particularly with regards to potassium and phosphorus. The heavy metals content, that is regarded as the main environmental disadvantage when using ash asa composting additive, did not negatively affect the final composts quality. However, some other controversial effects of ash, related to the moisture and temperature values attained during the process, pH (8.8-9.2 as compared to 8.2 of the unamended compost) and electrical conductivity levels (up to 53% higher as compared to the unamended compost) in the final composts, were also observed.

    This study critically evaluates the biological processes and techniques applied to remove nitrogen and phosphorus from the anaerobic supernatant produced from the treatment of the organic fraction of municipal solid waste (OFMSW) and from its co-digestion with other biodegradable organic waste (BOW) streams. The wide application of anaerobic digestion for the treatment of several organic waste streams results in the production of high quantities of anaerobic effluents. Such effluents are characterized by high nutrient content, because organic and particulate nitrogen and phosphorus are hydrolyzed in the anaerobic digestion process. Consequently, adequate post-treatment is required in order to comply with the existing land application and discharge legislation in the European Union countries. This may include physicochemical and biological processes, with the latter being more advantageous due to their lower cost. Nitrogen removal is accomplished through the conventional nitrification/denitrification, nitritation/denitritation and the complete autotrophic nitrogen removal process; the latter is accomplished by nitritation coupled with the anoxic ammonium oxidation process. As anaerobic digestion effluents are characterized by low COD/TKN ratio, conventional denitrification/nitrification is not an attractive option; short-cut nitrogen removal processes are more promising. Both suspended and attached growth processes have been employed to treat the anaerobic supernatant. Specifically, the sequencing batch reactor, the membrane bioreactor, the conventional activated sludge and the moving bed biofilm reactor processes have been investigated. Physicochemical phosphorus removal via struvite precipitation has been extensively examined. Enhanced biological phosphorus removal from the anaerobic supernatant can take place through the sequencing anaerobic/aerobic process. More recently, denitrifying phosphorus removal via nitrite or nitrate has been explored. The removal of

    The article discusses issues related to comprehensive development and introduction of technologies such as “Smart city”. The urgency of accelerating the development of such highly organized systems, primarily in terms of reducing threats to information security, is emphasized in the paper. In accordance with authors’ analysis of the composition and structure of the threats to information security, “Accessibility”, “Integrity” and “Confidentiality” are highlighted. Violation of any of them leads to harmful effects on the information and other system resources. The protection of “Accessibility” mobilizes one third of all efforts to ensure information security that must be taken into account when allocating protective actions. The threats associated with failure of the supporting infrastructure are also significantly reduced. But the threats associated with failures of the system itself and failures of users are clearly increasing. There is a high level of society and production informatization, and the threats to information security are changing accordingly.

Besides plenty of text, every good presentation, webpage or publication is usually spruced up with visual content: graphics, photos or even videos. But have you ever thought about whether you actually have the proper rights to use such imagery?   Just recently, a stock photo agency contacted CERN regarding an image published on a web page currently under CERN's responsibility. According to them, this image had been used without the proper rights and thus violated their copyright. As the web page is from 2007 and as is part of an EU funded project which has since ended, it is hard to check the facts.

    Biochars have a high variability in chemical composition, which is determined by types of feedstock and pyrolysis conditions. Inorganic compounds, such as N, P, K and Ca, retained in biochar could be released and become available to plants. The aim of this study was to understand the effect of biochar and compost addition, derived from the organic fraction of municipal solid wastes at two different pyrolysis temperatures 3000C (BC300) and 6000C (BC600), on phosphorus availability and plant growth of lettuce (Lactuca sativa L.) grown in an alkaline loam soil. This type of soil is widely available in Greece, leading us to investigate ways to increase its fertility. A 39 d growth period of lettuce was studied in a greenhouse in triplicate. Treatments comprised of control soils (no addition of biochar or compost), soils treated only with compost (5%) or biochar (5%), and combinations of biochar (5%) plus compost (5%). No fertilization was added to any of the treatments. One biomass cut was obtained. Plant shoot yield and height were determined along with elemental concentration (N, P, K, Ca, Mg, Mn, Fe, Zn, Cu) and uptake of shoots. Results showed that BC300 combined with compost significantly increased P uptake of lettuce. On the other hand, BC600 plus compost, along with the two biochar-only treatments, significantly decreased Ca and Mg uptake of lettuce. N, K, Fe, Zn, Mn and Cu uptakes were not affected by the application of biochar, compost or the combined treatments. Despite the significant increase of P uptake, plant height and shoot yield were not significantly influenced by any of the treatments.

    Full Text Available This article examines the historically contradictory development of the Collective Security Treaty Organization (CSTO following its 15th anniversary, and evaluates its political potential from the point of view of its assigned mandate. The evolution of international stability at the beginning of the century forced the contracting parties of the CSTO to formalize their mainly declarative interactions through the creation of a valid regional security organization. This new collective security forum enriched the cooperation mandate by establishing additional areas for mutual coordination including counterterrorism activities, measures to combat illegal migration and drug trafficking, strategies to respond to natural disasters and cybersecurity. The creation of the multitasking Collective Rapid Reaction Forces was the first significant step on the way to the practical realization of the CSTO. The Collective Security Strategy for the period ending in 2025 organizes the CSTO instruments of international cooperation within the CSTO crisis management framework and thus works to reduce the fragmentary nature of the CSTO. Despite the availability of the Collective Rapid Reaction Forces and the Collective Peace-Keeping Forces, the CSTO’s crisis management approach gives priority to political approaches and negotiation. Consequently, the multifunctional mandate of the CSTO predetermines its strategic role in Eurasia and allows it to achieve its political goals related to conservation of the common military and strategic area, the creation of a constraining effect, the facilitation of cooperation among law enforcement and intelligence agencies and the ability to contribute to the settlement of regional and local conflicts.

    Full Text Available This study aimed to evaluate the effect of initial moisture content on the in-vessel composting under air pressure of organic fraction of municipal solid waste in Morocco in terms of internal temperature, produced gases quantity, organic matter conversion rate, and the quality of the final composts.For this purpose, in-vessel bioreactor was designed and used to evaluate both appropriate initial air pressure and appropriate initial moisture content for the composting process. Moreover, 5 experiments were carried out within initial moisture content of 55%, 65%, 70%, 75% and 85%. The initial air pressure and the initial moisture content of the mixture showed a significant effect on the aerobic composting. The experimental results demonstrated that for composting organic waste, relatively high moisture contents are better at achieving higher temperatures and retaining them for longer times.This study suggested that an initial moisture content of around 75%, under 0.6 bar, can be considered as being suitable for efficient composting of organic fraction of municipal solid waste. These last conditions, allowed maximum value of temperature and final composting product with good physicochemical properties as well as higher organic matter degradation and higher gas production. Moreover, final compost obtained showed good maturity levels and can be used for agricultural applications.

    Homeland security and defense applications seek to reduce the risk of undesirable eventualities across physical space in real-time. With that functional requirement in mind, our work focused on the development of IP based agent telecommunication solutions for heterogeneous sensor / robotic intelligent "Things" that could be deployed across the internet. This paper explains how multi-organization information and device sharing alliances may be formed to enable organizations to act as agents of homeland security (in addition to other uses). Topics include: (i) using location-aware, agent based, real-time information sharing systems to integrate business systems, mobile devices, sensor and actuator based devices and embedded devices used in physical infrastructure assets, equipment and other man-made "Things"; (ii) organization-centric real-time information sharing spaces using on-demand XML schema formatted networks; (iii) object-oriented XML serialization as a methodology for heterogeneous device glue code; (iv) how complex requirements for inter / intra organization information and device ownership and sharing, security and access control, mobility and remote communication service, tailored solution life cycle management, service QoS, service and geographic scalability and the projection of remote physical presence (through sensing and robotics) and remote informational presence (knowledge of what is going elsewhere) can be more easily supported through feature inheritance with a rapid agent system development methodology; (v) how remote object identification and tracking can be supported across large areas; (vi) how agent synergy may be leveraged with analytics to complement heterogeneous device networks.

    A pilot-scale (1800 kg per batch capacity) autoclave used in this study reduces municipal solid waste to a debris contaminated pulp product that is efficiently separated into its renewable organic content and non-renewable organic content fractions using a rotary trommel screen. The renewable organic content can be recovered at nearly 90% efficiency and the trommel rejects are also much easier to sort for recovery. This study provides the evaluation of autoclave operation, including mass and energy balances for the purpose of integration into organic diversion systems. Several methods of cooking municipal solid waste were explored from indirect oil heating only, a combination of oil and direct steam during the same cooking cycle, and steam only. Gross energy requirements averaged 1290 kJ kg(-1) material in vessel, including the weight of free water and steam added during heating. On average, steam recovery can recoup 43% of the water added and 30% of the energy, supplying on average 40% of steam requirements for the next cook. Steam recycle from one vessel to the next can reduce gross energy requirements to an average of 790 kJ kg(-1). © The Author(s) 2016.

    Purpose: To estimate organ and effective radiation doses due to backscatter security scanners using Monte Carlo simulations and a voxelized phantom set. Methods: Voxelized phantoms of male and female adults and children were used with the GEANT4 toolkit to simulate a backscatter security scan. The backscatter system was modeled based on specifications available in the literature. The simulations modeled a 50 kVp spectrum with 1.0 mm-aluminum-equivalent filtration and a previously measured exposure of approximately 4.6 μR at 30 cm from the source. Photons and secondary interactions were tracked from the source until they reached zero kinetic energy or exited from the simulation’s boundaries. The energy deposited in the phantoms’ respective organs was tallied and used to calculate total organ dose and total effective dose for frontal, rear, and full scans with subjects located 30 and 75 cm from the source. Results: For a full screen, all phantoms’ total effective doses were below the established 0.25 μSv standard, with an estimated maximum total effective dose of 0.07 μSv for full screen of a male child. The estimated maximum organ dose due to a full screen was 1.03 μGy, deposited in the adipose tissue of the male child phantom when located 30 cm from the source. All organ dose estimates had a coefficient of variation of less than 3% for a frontal scan and less than 11% for a rear scan. Conclusions: Backscatter security scanners deposit dose in organs beyond the skin. The effective dose is below recommended standards set by the Health Physics Society (HPS) and the American National Standards Institute (ANSI) assuming the system provides a maximum exposure of approximately 4.6 μR at 30 cm.

  9. Promoting Organ Donor Registries Through Public Education: What Is the Cost of Securing Organ Donors?

    Transplant medicine's impact on America's public health is seriously limited by acute shortage of transplantable organs. Consequently, the United Sates has witnessed considerable investment in the promotion of organ donor registries. Although there is no evidence to support that donor registry promotion alleviates organ shortage, this belief continues to drive investments into registry promotion. In this study, return on investment in donor registry promotion was examined using cost-outcomes analysis. Cost of promoting the donor registry was estimated in US dollars whereas the outcome was measured as the number of individuals who join the registry (registrants) and their value in terms of organ donors. The study was conducted from the perspective of a regional Organ Procurement Organization (OPO). Costs were directly obtained from the OPO. The number of new registrants was obtained from the OPO and the departments of motor vehicles that maintain the donor registry. The value of registrants in terms of organ donors was computed based on a registrant's age-dependent risk of dying and age-dependent probability of becoming an organ donor. Six thousand seven hundred eight individuals joined the organ donor registry (95% confidence interval [95% CI], 5429-7956) at a cost of $455 per registrant (95% CI, US $383-US $562). These individuals result in 4.2 present-day donors (95% CI, 2.5-6.6) at a cost of US $726 000 (95% CI, US $462000-US $1.2 million). Because the cost per registrant and cost per donor is less than society's willingness to pay, donor registry promotion offers positive return on investment. Investment in registry promotion should at the minimum be maintained at current levels.

    Growth of bacterial and archaeal species capable of interspecies electron exchange was stimulated by addition of conductive materials (carbon cloth or granular activated carbon (GAC)) to anaerobic digesters treating dog food (a substitute for the dry-organic fraction of municipal solid waste (OFMSW)). Methane production (772-1428mmol vs carbon cloth than controls. OFMSW degradation was also significantly accelerated and VFA concentrations were substantially lower in reactors amended with conductive materials. These results suggest that both conductive materials (carbon cloth and GAC) can promote conversion of OFMSW to methane even in the presence of extremely high VFA concentrations (∼500mM).

    2016-01-01

    In Africa and South Asia, where nutrition insecurity is severe, two of the most prominent production technologies are genetically modified (GM) crops and certified organic agriculture. We analyze the potential impact pathways from agricultural production to nutrition. Our review of data and the literature reveals increasing farm-level income from cash crop production as the main pathway by which organic agriculture and GM agriculture improve nutrition. Potential secondary pathways include reduced prices of important food crops like maize due to GM maize production and increased food production using organic technology. Potential tertiary pathways are improvements in health due to reduced insecticide use. Challenges to the technologies achieving their impact include the politics of GM agriculture and the certification costs of organic agriculture. Given the importance of agricultural production in addressing nutrition security, accentuated by the post-2015 sustainable development agenda, the chapter concludes by stressing the importance of private and public sector research in improving the productivity and adoption of both GM and organic crops. In addition, the chapter reminds readers that increased farm income and productivity require complementary investments in health, education, food access and women's empowerment to actually improve nutrition security. © 2016 S.

    The security of the networks has been an important concern for any organization. This is especially important for the defense sector as to get unauthorized access to the sensitive information of an organization has been the prime desire for cyber criminals. Many network security techniques like Firewall, VPN Concentrator etc. are deployed at the perimeter of network to deal with attack(s) that occur(s) from exterior of network. But any vulnerability that causes to penetrate the network's perimeter of defense, can exploit the entire network. To deal with such vulnerabilities a system has been evolved with the purpose of generating an alert for any malicious activity triggered against the network and its resources, termed as Intrusion Detection System (IDS). The traditional IDS have still some deficiencies like generating large number of alerts, containing both true and false one etc. By automatically classifying (correlating) various alerts, the high-level analysis of the security status of network can be identified and the job of network security administrator becomes much easier. In this paper we propose to utilize Self Organizing Maps (SOM); an Artificial Neural Network for correlating large amount of logged intrusion alerts based on generic features such as Source/Destination IP Addresses, Port No, Signature ID etc. The different ways in which alerts can be correlated by Artificial Intelligence techniques are also discussed. . We've shown that the strategy described in the paper improves the efficiency of IDS by better correlating the alerts, leading to reduced false positives and increased competence of network administrator.

    The mathematical model of coordination when ensuring complex security of the organization is considered. On the basis of use of a method of casual search three types of algorithms of effective coordination adequate to mismatch level concerning security are developed: a coordination algorithm at domination of instructions of the coordinator; a coordination algorithm at domination of decisions of performers; a coordination algorithm at parity of interests of the coordinator and performers. Assessment of convergence of the algorithms considered above it was made by carrying out a computing experiment. The described algorithms of coordination have property of convergence in the sense stated above. And, the following regularity is revealed: than more simply in the structural relation the algorithm, for the smaller number of iterations is provided to those its convergence.

    Health communication scholars are uniquely positioned to examine the ways in which individuals organize to address current and future exigencies related to social ills. In particular, organizations are key sites in understanding our health decisions related to food choice. From a young age, children develop habits of eating that stay with them throughout their life. More specifically, food insecurity impacts childhood nutrition. Children from low-income homes experience disproportional negative health outcomes. Appalachian Ohio is an area within the United States that experiences severe poverty. In 2013, community members in a small public school district in Appalachian Ohio formed the Appalachian Nutrition Advisory Council to address the nutritional needs of students in schools. This project stories the ways in which community members creatively organized to supplement existing structures in place designed to address school nutrition and food security.

    Full Text Available There are several applications connected to IT health devices on the self-organizing software platform (SoSp that allow patients or elderly users to be cared for remotely by their family doctors under normal circumstances or during emergencies. An evaluation of the SoSp applied through PAAR watch/self-organizing software platform router was conducted targeting a simple user interface for aging users, without the existence of extrasettings based on patient movement. On the other hand, like normal medical records, the access to, and transmission of, health information via PAAR watch/self-organizing software platform requires privacy protection. This paper proposes a security framework for health information management of the SoSp. The proposed framework was designed to ensure easy detection of identification information for typical users. In addition, it provides powerful protection of the user’s health information.

    Nowadays developing methods for distributed computing is received much attention. One of the methods of distributed computing is using of multi-agent systems. The organization of distributed computing based on the conventional network computers can experience security threats performed by computational processes. Authors have developed the unified agent algorithm of control system of computing network nodes operation. Network PCs is used as computing nodes. The proposed multi-agent control system for the implementation of distributed computing allows in a short time to organize using of the processing power of computers any existing network to solve large-task by creating a distributed computing. Agents based on a computer network can: configure a distributed computing system; to distribute the computational load among computers operated agents; perform optimization distributed computing system according to the computing power of computers on the network. The number of computers connected to the network can be increased by connecting computers to the new computer system, which leads to an increase in overall processing power. Adding multi-agent system in the central agent increases the security of distributed computing. This organization of the distributed computing system reduces the problem solving time and increase fault tolerance (vitality) of computing processes in a changing computing environment (dynamic change of the number of computers on the network). Developed a multi-agent system detects cases of falsification of the results of a distributed system, which may lead to wrong decisions. In addition, the system checks and corrects wrong results.

    For the co-fermentation of organic waste and sewage sludge in digester towers at municipal sewage treatment plant, mainly single-stage processes have so far been studied or are in use in part. Within the framework of a project sponsored by the foundation Oswald-Schulze-Stiftung, the use of a two-stage mode of operation (thermophilic/mesophilic) for co-fermenting organic waste and sewage sludge was investigated. By adding organic waste to the digester content, biogas production per reactor volume was more than doubled in comparison with exclusive sewage sludge fermentation. Because of the thermophilic stage for the conditioning of organic waste, specific biogas yield for an organic load of 1.5 kg organic dry residue TR/m{sup 3*}d was slightly enhanced in comparison with single-stage co-fermentation.

    Full Text Available BACKGROUND: There is stigma attached to the identification of residents carrying antimicrobial resistant organisms (ARO in long term care homes, yet there is a need to collect data about their prevalence for public health surveillance and intervention purposes. OBJECTIVE: We conducted a point prevalence study to assess ARO rates in long term care homes in Ontario using a secure data collection system. METHODS: All long term care homes in the province were asked to provide colonization or infection counts for methicillin-resistant Staphylococcus aureus (MRSA, vancomycin-resistant enterococci (VRE, and extended-spectrum beta-lactamase (ESBL as recorded in their electronic medical records, and the number of current residents. Data was collected online during the October-November 2011 period using a Paillier cryptosystem that allows computation on encrypted data. RESULTS: A provably secure data collection system was implemented. Overall, 82% of the homes in the province responded. MRSA was the most frequent ARO identified at 3 cases per 100 residents, followed by ESBL at 0.83 per 100 residents, and VRE at 0.56 per 100 residents. The microbiological findings and their distribution were consistent with available provincial laboratory data reporting test results for AROs in hospitals. CONCLUSIONS: We describe an ARO point prevalence study which demonstrated the feasibility of collecting data from long term care homes securely across the province and providing strong privacy and confidentiality assurances, while obtaining high response rates.

  3. Energy Contribution of OFMSW (Organic Fraction of Municipal Solid Waste to Energy-Environmental Sustainability in Urban Areas at Small Scale

    2017-02-01

    Full Text Available Urban waste management is one of the most challenging issues in energy planning of medium and large cities. In addition to the traditional landfill method, many studies are investigating energy harvesting from waste, not as a panacea but as a foreseeable solution. Thermo-chemical conversion to biogas, or even bio-methane under certain conditions, could be an option to address this challenge. This study focuses on municipal solid waste conversion to biogas as a local energy supply for the cities. Three urban models and their subdivision into urban areas were identified along with a typical Organic Fraction of Municipal Solid Waste (OFMSW matrix for each urban area. Then, an energy analysis was carried out to provide an optimization map for an informed choice by urban policy-makers and stakeholders. The results highlighted how the urban context and its use could affect the opportunity to produce energy from waste or to convert it in fuel. So, in this case, sustainability means waste turning from a problem to a renewable resource.

    Full Text Available The objective of this study is to analyze the satisfaction of participants in the offered programs of exercise of health and fitness clubs for municipal Youth and Sport organizations. A random sample of 320 participants was selected from 18 closed halls and responded to a questionnaire that was pre-checked for reliability, validity and objectivity (Chen, 2001. The questionnaire included questions related to demographics, participant satisfaction from the exercise programs and from the level of organisation these have, the quality of equipment the athletic halls have and the variety of services offered. Data was analysed statistically to determine the relationships and differences between the mean value of the different variables. Results show that the profile of the major customer segment is women from 26 to 35 years old with University education. Also, statistical analysis shows that there are significant differences between the average values in all 5 dimensions of participant satisfaction: the prices of exercise programs, program content, the quality of hall equipment, public relations and employee performance. Also, there are statistically significant differences between the demographic variables (age, sex, income and the 5 participant satisfaction dimensions. However, the dimensions that present statistically significant differences vary according to the demographic variable analysed. This shows that municipal sports centres should differentiate their offers according to the dimensions of satisfaction that are more important for each customer segment as these are formed based on age, income or sex.

    The move towards environmental sustainability in the Canadian industrial, agricultural and municipal sectors coupled with the requirements for Canada to meet its Kyoto obligations for reduction of greenhouse gas (GHG) emissions have led to the need to examine the feasibility of harvesting the energy contained in waste biomass. This paper discussed the current and projected Canadian inventories of municipal biosolids, municipal solid waste, food industry wastes and animal manure; anaerobic digestion; considerations and challenges in the management of waste biomass; and current technologies available for energy recovery for each of these waste streams. The paper also discussed the environmental, technical, economic, societal and regulatory issues which are likely to be triggered as alternative methods to traditional disposal practices. The research and action needed to bring Canada to the forefront of environmental sustainability in waste biomass management was also discussed. The paper made several recommendations in terms of regulations, demonstration projects and public education. It was concluded that the biggest factor in the adoption of technologies for waste management is cost. It was concluded that there is no one perfect solution to the management of organic wastes in Canada. A detailed analysis that takes into consideration all of the technical, societal, environmental, economic, and regulatory issues must be performed to determine the right choice of technology. 4 tabs.

    The panel discussing market opportunities for municipal electric companies was moderated by Markham Mayor Don Cousens. He expressed himself in favour of deregulation and was optimistic about the benefits it will bring to municipal electric utilities and their customers. Barry Chuddy, General Manager of Business Development for TransAlta Energy discussed the advantages of recent cogeneration and district energy for municipal utilities in Ontario and Quebec, and expressed his support for incentive-based regulation based on a level playing field, competitive generation, and a reasonable charge for stranded assets. Toronto City Councillor Dan Leckie described cogeneration and district energy as a tremendous opportunity to reduce the cost of doing business in the city core through local job creation and by keeping money in the local economy. Karl Wahl, General Manager of Hydro Mississauga expressed optimism that the government will move expeditiously toward competition, choice and lower-cost supply. David McGarry, President of Elecsar Engineering of Sarnia spoke about the significant job creating potential that deregulation will bring to the electrical industry. He cited several examples from Ontario and British Columbia

    The daily municipal solid waste (MSW) generation in the Mexico City Metropolitan Area (MCMA) is the highest nationwide (˜26000 ton day -1); this amount is discarded in sanitary landfills and controlled dumps. Information about the type and concentration of potential pollutants contained in landfill gas (LFG) from these MSW disposal sites is limited. This study intends to generate information about the composition of LFG from five MSW disposal sites with different operational characteristics and stages, in order to identify their contribution as potential pollutant sources of total gaseous mercury (TGM) and volatile organic compounds (VOCs). Important methane (CH 4) contents (>55%) in LFG were registered at three of the five sites, while two sites were found in semi-aerobic conditions (CH 4clay cover. High values of the TGM air/LFG ratio were also related to external TGM sources of influence, as a landfill in operation stage located at a highly industrialized area.

    In the first batch solid substrate anaerobic hydrogenogenic fermentation with intermittent venting (SSAHF-IV) of the organic fraction of municipal solid waste (OFMSW), a cumulative production of 16.6 mmol H(2)/reactor was obtained. Releases of hydrogen partial pressure first by intermittent venting and afterward by flushing headspace of reactors with inert gas N(2) allowed for further hydrogen production in a second to fourth incubation cycle, with no new inoculum nor substrate nor inhibitor added. After the fourth cycle, no more H(2) could be harvested. Interestingly, accumulated hydrogen in 4 cycles was 100% higher than that produced in the first cycle alone. At the end of incubation, partial pressure of H(2) was near zero whereas high concentrations of organic acids and solvents remained in the spent solids. So, since approximate mass balances indicated that there was still a moderate amount of biodegradable matter in the spent solids we hypothesized that the organic metabolites imposed some kind of inhibition on further fermentation of digestates. Spent solids were washed to eliminate organic metabolites and they were used in a second SSAHF-IV. Two more cycles of H(2) production were obtained, with a cumulative production of ca. 2.4 mmol H(2)/mini-reactor. As a conclusion, washing of spent solids of a previous SSAHF-IV allowed for an increase of hydrogen production by 15% in a second run of SSAHF-IV, leading to the validation of our hypothesis.

    During the battle over comprehensive health care reform in the early 1990s, organized labor was not only unable to put together a winning coalition but also found itself divided and on the defensive as it struggled to prevent any further erosion of the private-sector safety net of the U.S. welfare state. Labor's relative ineffectiveness has deep institutional and political roots and was not merely a consequence of its dwindling membership base. Several key institutions of the private welfare state, notably the Taft-Hartley health and welfare funds and the Employment Retirement Income Security Act (ERISA) preemption, brought the interests of organized labor more closely in line with those of large employers and commercial insurers and aggravated divisions within organized labor and between unions and public interest groups. In addition, several political factors conspired to reinforce labor's tendency to stick to a policy path on health care issues that was predicated on an employer-mandate solution and that had been charted primarily by business and leading Democrats. As a result, organized labor did not emerge from the 1993-1994 struggle with its political base fortified nor with a viable long-term political strategy to achieve universal health care and to shift the political debate over health policy in a more desirable direction.

    Wildlife has received much attention during last decades as an indicator of ecosystems health. Kubiak at al. (1989) showed that there are significant effect on reproductive success due to organochlorines, not only in hatching success, but also in chick health. Due to the widespread distribution of these xenoestrogens, there is a need for screening and risk evaluation of these endocrine disrupters in living organisms from the global point of view of ecosystems health. Aspects of the life history of the black kites (Milvus migrans) make them a useful species for contaminants monitoring. They are long-lived birds, adapt well to human areas and many feeds at dumps, garbage tips, etc. where a wide range of contaminants can be found3. Effects of chlorinated pollutants have not been widely studied in this species. In 2001, a monitoring program was initiated in order to evaluate the health of a population of black kites nesting in the Regional Park of the Southeastern of Madrid (RPSM), Spain. This study is part of a larger research investigation of the influence of a Municipal Solid Waste Incinerator (MSWI) on the kites'surroundings. Since Municipal Solid Waste Incinerators (MSWI) are suspected to produce some highly toxic POPs (Persistent Organic Pollutants) such as polychlorinated dibenzo-pdioxins (PCDDs) and polychlorinated dibenzo-furans (PCDFs) as well as other short of toxic chemicals (e.g. PCBs and heavy metals) this study was initiated with the aim of investigating the potential toxicity of these compounds on the kites population. The purpose of this study was to conduct the evaluation in a non-destructive way. Since eggs are known to reflect the accumulation of lipophilic contaminants in birds, the study was based on the use of unhatched eggs obtained from black kites.

    Waste causes environmental pollution and greenhouse gas (GHG) emissions when it is not managed sustainably. In Bangladesh, municipal organic waste (MOW) is partially collected and landfilled. Thus, it causes deterioration of the environment urging a recycle-oriented waste management system. In this study, we propose a waste management system through pyrolysis of selective MOW for biochar production and composting of the remainder with biochar as an additive. We estimated the carbon (C), nitrogen (N), phosphorus (P) and potassium (K) recycling potentials in the new techniques of waste management. Waste generation of a city was calculated using population density and per capita waste generation rate (PWGR). Two indicators of economic development, i.e., gross domestic product (GDP) and per capita gross national income (GNI) were used to adopt PWGR with a projected contribution of 5-20% to waste generation. The projected PWGR was then validated with a survey. The waste generation from urban areas of Bangladesh in 2016 was estimated between 15,507 and 15,888 t day -1 with a large share (∼75%) of organic waste. Adoption of the proposed system could produce 3936 t day -1 biochar blended compost with an annual return of US $210 million in 2016 while it could reduce GHG emission substantially (-503 CO 2 e t -1 municipal waste). Moreover, the proposed system would able to recover ∼46%, 54%, 54% and 61% of total C, N, P and K content in the initial waste, respectively. We also provide a projection of waste generation and nutrient recycling potentials for the year 2035. The proposed method could be a self-sustaining policy option for waste management as it would generate ∼US$51 from each tonne of waste. Moreover, a significant amount of nutrients can be recycled to agriculture while contributing to the reduction in environmental pollution and GHG emission. Copyright © 2018 Elsevier Ltd.

  12. Sorption and release of organics by primary, anaerobic, and aerobic activated sludge mixed with raw municipal wastewater.

    Directory of Open Access Journals (Sweden)

    Oskar Modin

    Full Text Available New activated sludge processes that utilize sorption as a major mechanism for organics removal are being developed to maximize energy recovery from wastewater organics, or as enhanced primary treatment technologies. To model and optimize sorption-based activated sludge processes, further knowledge about sorption of organics onto sludge is needed. This study compared primary-, anaerobic-, and aerobic activated sludge as sorbents, determined sorption capacity and kinetics, and investigated some characteristics of the organics being sorbed. Batch sorption assays were carried out without aeration at a mixing velocity of 200 rpm. Only aerobic activated sludge showed net sorption of organics. Sorption of dissolved organics occurred by a near-instantaneous sorption event followed by a slower process that obeyed 1st order kinetics. Sorption of particulates also followed 1st order kinetics but there was no instantaneous sorption event; instead there was a release of particles upon mixing. The 5-min sorption capacity of activated sludge was 6.5±10.8 mg total organic carbon (TOC per g volatile suspend solids (VSS for particulate organics and 5.0±4.7 mgTOC/gVSS for dissolved organics. The observed instantaneous sorption appeared to be mainly due to organics larger than 20 kDa in size being sorbed, although molecules with a size of about 200 Da with strong UV absorbance at 215-230 nm were also rapidly removed.

    Bio-hydrogen production from dry thermophilic anaerobic co-digestion (55°C and 20% total solids) of organic fraction of municipal solid waste (OFMSW) and food waste (FW) was studied. OFMSW coming from mechanical-biological treatment plants (MBT plants) presents a low organic matter concentration. However, FW has a high organic matter content but several problems by accumulation of volatile fatty acids (VFAs) and system acidification. Tests were conducted using a mixture ratio of 80:20 (OFSMW:FW), to avoid the aforementioned problems. Different solid retention times (SRTs) - 6.6, 4.4, 2.4 and 1.9 days - were tested. It was noted that addition of food waste enhances the hydrogen production in all the SRTs tested. Best results were obtained at 1.9-day SRT. It was observed an increase from 0.64 to 2.51 L H2/L(reactor) day in hydrogen productivity when SRTs decrease from 6.6 to 1.9 days. However, the hydrogen yield increases slightly from 33.7 to 38 mL H2/gVS(added). Copyright © 2015 Elsevier Ltd. All rights reserved.

    The separation of biowaste at home is key to improving, facilitating and reducing the operational costs of the treatment of organic municipal waste. The conventional method of collecting such waste and separating it at home is usually done by using a sealed bin with a plastic bag. The use of modern compostable bags is starting to be implemented in some European countries. These compostable bags are made of biodegradable polymers, often from renewable sources. In addition to compostable bags, a new model of bin is also promoted that has a perforated surface that, together with the compostable bag, makes the so-called "aerated system". In this study, different combinations of home collection systems have been systematically studied in the laboratory and at home. The results obtained quantitatively demonstrate that the aerated bin and compostable bag system combination is effective at improving the collection of biowaste without significant gaseous emissions and preparing the organic waste for further composting as concluded from the respiration indices. In terms of weight loss, temperature, gas emissions, respiration index and organic matter reduction, the best results were achieved with the aerated system. At the same time, a qualitative study of bin and bag combinations was carried in 100 homes in which more than 80% of the families participating preferred the aerated system.

    Removal of the refractory organic matters in leachate brines generated from nanofiltration unit in two full-scale municipal solid waste landfill leachate treatment plants was investigated by Fenton oxidative-coagulation and ultraviolet photo - Fenton processes in this study. Fenton oxidative-coagulation was performed under the condition of an initial pH of 5.0 and low H2O2/Fe(2+) ratios. After precipitate separation, the remaining organic constituents were further oxidized by photo - Fenton process. For both leachate brines with varying pollution strength, more than 90% COD and TOC reductions were achieved at H2O2/Fe(2+) dosages of 35 mM/8 mM and 90 mM/10 mM, respectively. The effluent COD ranged 120-160 mg/L under the optimal operating conditions, and the biodegradability was increased significantly. Fenton oxidative-coagulation was demonstrated to contribute nearly 70% overall removal of organic matters. In the combined processes, the efficiency of hydrogen peroxide varied from 216 to 228%, which may significantly reduce the operating cost of conventional Fenton method. Six phthalic acid esters and thirteen polycyclic aromatic hydrocarbons were found in leachate brines, and, on the average, around 80% phthalic acid esters and 90% polycyclic aromatic hydrocarbons were removed by the combined treatments.

    Full Text Available Cape Verde, an island country with few natural resources and with adverse soil and weather conditions, imports most of the foodstuffs that need. Local production, although scarce, is relevant to food security. This article reflects a case study in the municipality of Ribeira Grande, island of Santo Antão -Cape Verde, whose aim was to study the role of three production systems in the generation of income, food security and improving the quality of life of families. These systems are: vegetable production, rainfed production and sugar cane production. A total of 105 surveys were carried out in the localities of Ribeirão and Garça de Cima, equally distributed among different agricultural producers. It was found that the sugar cane producers have an average annual income superior to horticulture and rainfed farmers, 402,154, 337,602 and 259,764 CVE respectively (1 euro = 110.265 Cape Verdean escudos – CVE. With respect to food intake, the differences are not significant. Horticulture farmers have a calorie intake of 2959.71, rainfed producers 2926.65 and sugar cane producers 2888.86 kcal/EM/day. With regard to indicators of quality of life, the families of horticulture farmers and sugar cane producers present similar results, superior to the rainfed producers’ families.

    Full Text Available ABSTRACT: The universalization of the right to social security for rural producers and rural workers is a recent victory for Brazilian society. The implementation of this benefit began in the early 1990s. This article aimed to analyze the effects of rural social security on the lifestyle of families with retirees. The research was conducted in two small municipalities with agricultural economies from Zona da Mata Mineira region. The research used cross-sectional data collection procedures by applying a survey with open and closed-ended questions about consumption and living. The research sample was representative of the study population, comprising 117 rural elderly people, 64 from Piranga City and 53 from São Miguel do Anta City. Data obtained were categorized, analyzed and tested using Statistical Package for Social Sciences (SPSS software. The survey results highlighted routine behavior and a predisposition to act based on a long term planning system, supported by the certainty of receiving the pension. Planned and long-term investments became a reality, including home improvement projects and acquisition of durable goods. Concerns about immediate family maintenance gave way to a perspective based on future planning.

  1. Bioenergy and bioproducts from municipal organic waste as alternative to landfilling: a comparative life cycle assessment with prospective application to Mexico.

    A life cycle assessment (LCA) of a four-stage biorefinery concept, coined H-M-Z-S, that converts 1 t of organic fraction of municipal solid waste (OFMSW) into bioenergy and bioproducts was performed in order to determine whether it could be an alternative to common disposal of OFMSW in landfills in the Mexican reality. The OFMSW is first fermented for hydrogen production, then the fermentates are distributed 40 % to the methane production, 40 % to enzyme production, and 20 % to the saccharification stage. From hydrogen and methane, up to 267 MJ and 204 kWh of gross heat and electricity were produced. The biorefinery proved to be self-sustainable in terms of power (95 kWh net power), but it presented a deficit of energy for heating services (-155 MJ), which was partially alleviated by digesting the wastes from the bioproducts stages (-84 MJ). Compared to landfill, biorefinery showed lower environmental impacts in global warming (down to -128 kg CO 2 -eq), ozone layer depletion (2.96 × 10 -6  kg CFC 11 -eq), and photochemical oxidation potentials (0.011 kg C 2 H 4 -eq). The landfarming of the digestates increased significantly the eutrophication impacts, up to 20 % below the eutrophication from landfilling (1.425 kg PO 4 -eq). These results suggest that H-M-Z-S biorefinery could be an attractive alternative compared to conventional landfilling for the management of municipal solid wastes, although new alternatives and uses of co-products and wastes should be explored and tested. Moreover, the biorefinery system would benefit from the integration into the market chain of the bioproducts, i.e., enzymes and hydrolysates among others.

    2016-01-01

    A model was developed to assess the impact of adding acids and bases to processed municipal sewage sludge (MSS) to mobilize contaminants, facilitating their removal from sludge by flushing prior to land application. Among 312 organic contaminants documented to occur in U.S. MSS, 71 or 23% were identified as ionizable organic contaminants (IOCs), contributing a disproportionately large fraction of 82% of the total mass of sludge-borne contaminants. Detected IOCs included 57 pharmaceuticals and personal care products, 12 perfluorinated compounds, one surfactant and one pesticide. Annually, about 2000 t of IOCs were estimated to be released to U.S. soils via land-application of MSS. A partitioning model developed to assess the impact of pH on hydrophobic sorption revealed that between 36 and 85% of the mass of individual classes of IOCs potentially could be desorbed from MSS via pH adjustment and flushing. Thus, modeling results suggest that a sequential pH treatment [acidic (~ pH 2) followed by basic (~ pH 12) treatment] has the potential to reduce the burden of harmful IOCs in MSS applied on U.S. land by up to 40 ± 16 t annually. This approach may serve as a cost-effective treatment process that can be implemented easily in existing sludge treatment infrastructure in the U.S. and worldwide, serving to significantly improve the quality of MSS destined for land application. - Highlights: • Sorption model predicts the leachability of ionizable organics from sludge. • Ionic organics make up 82% of total contaminant mass in U.S. sludge. • 36–85% of ionic organic pollutants are removable by pH treatment. • Proposed sludge treatment promises cost-effective risk reduction.

    The aim of this study was to investigate the effect of mixing ratio of co-anaerobic digestion between dewatered waste sludge from municipal wastewater treatment plant (DS) and organic fraction of food waste (FW). The experiment was carried out in 3L reactors for 16 days at ambient temperature. Four mixing ratios of DW and FW was investigated including 100 % DS : 0 % FW (Run S100); 75% DS : 25 % FW (Run S75); 50% DS : 50% FW (Run S50); and 25% DS : 75% FW (Run S25) in term of VS concentration. As a result, the Run S50 achieved best performance among the four funs indicated in biogas accumulation of 32.48 L biogas and methane yield of 358.9 400ml CH4/g VS removal after 16 days operation at ambient temperature. Biogas accumulation of Run S25 was higher than that of Run S75. Run S100 produced the lowest of biogas of all runs. It is concluded that co-anaerobic digestion of different organic sources could enhance the performance of methane fermentation.

    2017-12-01

    During the last decades, the global industrial production partly shifted from industrialized nations to emerging and developing countries. In these upcoming economies, the newly developed industrial centers are generally located in densely populated areas, resulting in the discharge of often only partially treated industrial and municipal wastewaters into the surface waters. There is a huge gap of knowledge about the composition of the complex organic pollutant mixtures occurring in such heavily impacted areas. Therefore, we applied a non-target screening to comprehensively assess river pollution in a large industrial area located in the megacity Jakarta. More than 100 structurally diverse organic contaminants were identified, some of which were reported here for the first time as environmental contaminants. The concentrations of paper manufacturing chemicals in river water-for example, of the endocrine-disrupting compound bisphenol A (50-8000 ng L -1 )-were as high as in pure untreated paper industry wastewaters. The non-target screening approach is the adequate tool for the identification of water contaminants in the new global centers of industrial manufacturing-as the first crucial step towards the evaluation of as yet unrecognized environmental risks.

    The organic fraction of municipal solid waste (OFMSW), normally exceeding 60% of the waste stream in developing countries, could constitute a valuable source of feed for microbial fuel cells (MFCs). This study tested the start-up of two sets of OFMSW-fed air-cathode MFCs inoculated with wastewater sludge or cattle manure. The maximum power density obtained was 123±41mWm-2 in the manure-seeded MFCs and 116±29mWm-2 in the wastewater-seeded MFCs. Coulombic efficiencies ranged between 24±5% (manure-seeded MFCs) and 23±2% (wastewater-seeded MFCs). Chemical oxygen demand removal was >86% in all the MFCs and carbohydrate removal >98%. Microbial community analysis using 16S rRNA gene pyrosequencing demonstrated the dominance of the phylum Firmicutes (67%) on the anode suggesting the possible role of members of this phylum in electricity generation.

    The organic fraction of municipal solid waste (OFMSW), normally exceeding 60% of the waste stream in developing countries, could constitute a valuable source of feed for microbial fuel cells (MFCs). This study tested the start-up of two sets of OFMSW-fed air-cathode MFCs inoculated with wastewater sludge or cattle manure. The maximum power density obtained was 123±41mWm-2 in the manure-seeded MFCs and 116±29mWm-2 in the wastewater-seeded MFCs. Coulombic efficiencies ranged between 24±5% (manure-seeded MFCs) and 23±2% (wastewater-seeded MFCs). Chemical oxygen demand removal was >86% in all the MFCs and carbohydrate removal >98%.

    Different high feed organic loading rates (OLRs) (from 5.7 g to 46.0 g TVS/l/d) or hydraulic retention times (HRTs) (from 15 d to 2 d) in single-phase dry-thermophilic anaerobic digestion (AD) of organic fraction municipal solid waste (OFMSW) were investigated. The specific gas production (SGP) values (0.25-0.53 m(3)/kg TVS) and the percentages of Eubacteria, Archaea, H2-utilising methanogens (HUMs) and acetate-utilising methanogens (AUMs) were stable within the ranges 80.2-91.1%, 12.4-18.5%, 4.4-9.8% and 5.5-10.9%, respectively. A HUM/AUM ratio greater than 0.7 seems to be necessary to maintain very low partial pressures of H2 required for dry AD process. Increasing OLR resulted in an increase in all the populations, except for propionate-utilising acetogens (PUAs). Optimal conditions were obtained at 3d HRT (OLR=30.7 g TVS/l/d), which is lower than the doubling time of acetogens and methanogens. The methane production (MP) was clearly higher than those reported in AD of OFMSW. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Pit lakes (abandoned flooded mine pits) represent a potentially valuable water resource in hot arid regions. However, pit lake water is often characterised by low pH with high dissolved metal concentrations resulting from Acidic and Metalliferous Drainage (AMD). Addition of organic matter to pit lakes to enhance microbial sulphate reduction is a potential cost effective remediation strategy. However, cost and availability of suitable organic substrates are often limiting. Nevertheless, large quantities of sewage and green waste (organic garden waste) are often available at mine sites from nearby service towns. We treated AMD pit lake water (pH 2.4) from tropical, North Queensland, Australia, with primary-treated sewage sludge, green waste, and a mixture of sewage and green waste (1:1) in a controlled microcosm experiment (4.5 L). Treatments were assessed at two different rates of organic loading of 16:1 and 32:1 pit water:organic matter by mass. Combined green waste and sewage treatment was the optimal treatment with water pH increased to 5.5 in only 145 days with decreases of dissolved metal concentrations. Results indicated that green waste was a key component in the pH increase and concomitant heavy metal removal. Water quality remediation was primarily due to microbially-mediated sulphate reduction. The net result of this process was removal of sulphate and metal solutes to sediment mainly as monosulfides. During the treatment process NH(3) and H(2)S gases were produced, albeit at below concentrations of concern. Total coliforms were abundant in all green waste-treatments, however, faecal coliforms were absent from all treatments. This study demonstrates addition of low-grade organic materials has promise for bioremediation of acidic waters and warrants further experimental investigation into feasibility at higher scales of application such as pit lakes.

  14. The Korean Peninsula Energy Development Organization : implications for Northeast Asian regional security co-operation?

    International Nuclear Information System (INIS)

    Snyder, S.

    2000-01-01

    This paper identifies opportunities for co-operation on regional development and security in the North Pacific region. The Korean Peninsula Energy Development Organization (KEDO) was created in 1993 during bilateral negotiations between the United States and the Democratic People's Republic of Korea (US-DPRK) over North Korea's alleged nuclear weapons program. The negotiations resulted in an agreement to freeze North Korea's known nuclear weapons program in return for the construction of two proliferation-resistant 100 MWe light water reactors (LWR) in North Korea, and the provision of 500,000 tons of heavy fuel oil per year until the completion of the LWR construction as compensation for lost energy production capacity resulting from the shutting down of North Korea's nuclear reactors. The author described the activities of KEDO and examined its internal dynamics. The unique circumstances that produced the Agreed Framework and KEDO in response to a major international crisis of the nuclear program in the DPRK were also highlighted along with the US-DPRK bilateral agreement and the multilateral institution involving the United States, South Korea, Japan and the European Union. Financial support from Australia and Canada was discussed along with the mechanism for engaging North Korea in regularized interaction and technical cooperation. It was concluded that KEDO's record of successes and failures is mixed. The energy security issue has been identified as an area that could result in conflict among Northeast Asian countries which are increasingly dependent on oil supplies from the Middle East. In response, numerous multilateral financing mechanisms have been developed to promote joint business opportunities that exploit natural gas resources in the Russian Far East to address Japanese, Korean and Chinese energy needs. 35 refs

    The aim of this study was to survey minor home help services provided by Swedish municipalities with the main purpose to prevent fall injuries. If minor home help services were presented on the homepage of a municipality, an initial telephone contact was taken. Thereafter a questionnaire was administered, including questions about target groups, aim with the services, tasks included, costs and restrictions for users, budget, and experienced gains with the services. Municipalities not providing minor home help services were asked about the reason therefore and if the municipality had previously provided the services Results: The questionnaire response rate was 92%. In 191 of Sweden's 290 municipalities services were provided by, or in cooperation with, the municipality. Reasons for not providing the services were mainly financial and lack of demand. Services were more often provided in larger cities and in municipalities located in populous regions. In some municipalities services were performed by persons with functional disabilities or unemployed persons. Both providers and users expressed satisfaction with the services aspects expressed were that services lead to greater sense of safety and social gains the effect of the services in terms of fall prevention is yet to be proved with only a small fall-preventive effect services are probably cost-effective improved quality of life, sense of safety, and being able to offer meaningful work to otherwise unemployed persons are important aspects that might in themselves motivate the provision of minor home help services. © 2014 the Nordic Societies of Public Health.

    Composting is a good alternative for the treatment of organic waste. However, an important amount of hazardous agents such as bioaerosols and volatile organic compounds may be released during the process. Therefore, the presence of microbiological and chemical pollutants emitted to air may mean a risk for the health of composting plants workers. We here report the results of an investigation aimed at evaluating the occupational exposure to chemical and biological agents for workers of an organic waste treatment facility (Montcada i Reixac, Catalonia, Spain). Total concentrations of bacteria and fungi (at 25 degrees C and 37 degrees C), including Aspergillus fumigatus, were determined on a 3-month basis in 4 areas of the composting plant (reception, sorting, composting and cogeneration halls). Non-cancer and cancer risks were assessed. Workers in the sorting cabins seemed to be the most exposed to pollutants. Consequently, the use of preventive measures, such as integrated P3 filter masks and gloves are highly recommended. On the other hand, the emission and dispersion of bioaerosols and particles should be minimized during the process through the application of additional measures, such as the humectation of waste and the installation of biofilters. The results of this study can be useful to elaborate occupational risk prevention programs for workers in composting plants.

    Full Text Available A cross sectional study was conducted from October 2010 to March 2011 to assess the prevalence, cyst viability, organ distribution and financial losses of bovine hydatidosis in cattle slaughtered at Dessie municipal abattoir. Postmortem inspection, cyst characterization and financial loss estimations were conducted. Out of 610 inspected cattle, 83 (13.61% were harbouring a single or multiple hydatid cysts. Significantly (P<0.05 higher infection rate was observed in poor (22.89% than medium (12.99% and good (10.40% body condition scorings but significant variation (P>0.05 was not observed in different age groups. Anatomically, the cysts were distributed 68.67% in the lung, 14.46% in the liver, 6.02% in the kidneys, 1.2% in the heart and 9.64% were found both in the lung and liver. Of the total examined cysts (195 for fertility and viability, 27 (13.85% were fertile, 44 (22.56% were calcified, 124 (63.59% were sterile. The rate of cyst calcification was higher in the liver (78.14% than other organs whilst the fertility percentage was higher in the lung (14.65%. Of the total 27 fertile cysts subjected to viability test, 13 (6.67% were viable. Size assessment made on 195 cysts indicated that 153 (78.46% were small, 41 (21.03% were medium and one (0.51% were large sized cysts. In the present study, the total annual economic loss from organ condemnation and carcass weight loss due to hydatidosis was estimated as 681,333.87 Ethiopian birr which is about 39157.12 United States dollar per annum based on the local market prices in the study period. The result of this study revealed that hydatidosis is an economically important disease of cattle which necessitates designing of appropriate strategies for its control. [Vet.

    Anaerobic digestion of source separated organic fraction of municipal solid waste is an increasing waste valorization alternative instead of incineration or landfilling of untreated biodegradable wastes. Nevertheless, a significant portion of biodegradable wastes entering the plant is lost in pre-treatments and post-treatments of anaerobic digestion facilities together with other improper materials such as plastics, paper, textile materials and metals. The rejected materials lost in these stages have two main implications: (i) less organic material enters to digesters and, as a consequence, there is a loss of biogas production and (ii) the rejected materials end up in landfills or incinerators contributing to environmental impacts such as global warming or eutrophication. The main goals of this study are (i) to estimate potential losses of biogas in the rejected solid materials generated during the pre- and post-treatments of two full-scale anaerobic digestion facilities and (ii) to evaluate the environmental burdens associated to the final disposal (landfill or incineration) of these rejected materials by means of Life Cycle Assessment. This study shows that there is a lost of potential biogas production, ranging from 8% to 15%, due to the loss of organic matter during pre-treatment stages in anaerobic digestion facilities. From an environmental point of view, the Life Cycle Assessment shows that the incineration scenario is the most favorable alternative for eight out of nine impact categories compared with the landfill scenario. The studied impact categories are Climate Change, Fossil depletion, Freshwater eutrophication, Marine eutrophication, Ozone depletion, Particulate matter formation, Photochemical oxidant formation, Terrestrial acidification and Water depletion.

    Organic food enables the promotion of Food and Nutritional Safety (FNS) and sustainable regional development. In this context, the National School Food Program (NSFD) seeks to comply with the requirements of FNS. This study evaluated the inclusion of organic food in school food in the municipalities of rural territories of the state of Rio Grande do Sul by means of interviews with local managers. Eight territories were visited, albeit of its 153 municipalities only 102 comprised the sample for this study. Of these, 20.58% said they buy organic produce from family farms. The Center South Territory revealed the highest percentage of purchase, in which 40% of the municipalities visited purchased organic produce, followed by the Center Mountain Territory with 33.3%, while the lowest percentage was 7.1% in the Countryside Territory. The study identified the need for intersectoral action to develop organic production, as well as stimulate the consumption of these foods in the school environment, in order to meet the requirements of FNS.

    Full Text Available The security of informational assets has always been a corporate requirement. These assets can be scaled in three main spheres, namely, people, organizational processes and technologies. The internet, the web, the broadcast of networks, and the growing presence of technology both in people's lives and in organizational contexts have caused profound transformations in the intrinsic processes that constitute personal and organizational routines. On the one hand, these changes provided by the technological progress have fostered competitiveness and decentralization; on the other hand, they require better management, control, security and protection for information and knowledge. This article presents the results of an investigation within information security realm, focusing on the human aspects of knowledge and information management related to security practices. Using a quality-quantitative approach, we identify behavioral actions and profiles of employees of a company in the field of healthcare, which reveal some connections with information security failures. We conclude that the human element is a relevant variable, even a critical one, for the management of information security in organizations.

    Full Text Available Biomass, in form of residues and waste, can be used to produce energy with low environmental impact. It is important to use the feedstock close to the places where waste are available, and with the shortest conversion pathway, to maximize the process efficiency. In particular waste vegetable oil and the organic fraction of municipal solid waste represent a good source for fuel production in urban areas. Dual fuel engines could be taken into consideration for an efficient management of these wastes. In fact, the dual fuel technology can achieve overall efficiencies typical of diesel engines with a cleaner exhaust emission. In this paper the feasibility of a cogeneration system fuelled with waste vegetable oil and biogas is discussed and the evaluation of performance and emissions is reported on the base of experimental activities on dual fuel heavy duty engine in comparison with diesel and spark ignition engines. The ratio of biogas potential from MSW and biodiesel potential from waste vegetable oil was estimated and it results suitable for dual fuel fuelling. An electric power installation of 70 kW every 10,000 people could be achieved.

  4. Parameters affecting the stability of the digestate from a two-stage anaerobic process treating the organic fraction of municipal solid waste

    This paper focused on the factors affecting the respiration rate of the digestate taken from a continuous anaerobic two-stage process treating the organic fraction of municipal solid waste (OFMSW). The process involved a hydrolytic reactor (HR) that produced a leachate fed to a submerged anaerobic membrane bioreactor (SAMBR). It was found that a volatile solids (VS) removal in the range 40-75% and an operating temperature in the HR between 21 and 35 o C resulted in digestates with similar respiration rates, with all digestates requiring 17 days of aeration before satisfying the British Standard Institution stability threshold of 16 mg CO 2 g VS -1 day -1 . Sanitization of the digestate at 65 o C for 7 days allowed a mature digestate to be obtained. At 4 g VS L -1 d -1 and Solid Retention Times (SRT) greater than 70 days, all the digestates emitted CO 2 at a rate lower than 25 mg CO 2 g VS -1 d -1 after 3 days of aeration, while at SRT lower than 20 days all the digestates displayed a respiration rate greater than 25 mg CO 2 g VS -1 d -1 . The compliance criteria for Class I digestate set by the European Commission (EC) and British Standard Institution (BSI) could not be met because of nickel and chromium contamination, which was probably due to attrition of the stainless steel stirrer in the HR.

    In the present study, the influence of substrate pre-treatment (grinding and sieving) on batch anaerobic digestion of the organic fraction of municipal solid waste (OFMSW) was first assessed, then followed by co-digestion experiments with the liquid fraction from hydrothermal carbonization (LFHTC) of dewatered sewage sludge (DSS). The methane yield of batch anaerobic digestion after grinding and sieving (20 mm diameter) the OFMSW was considerably higher (453 mL CH 4 STP g -1 VS added ) than that of untreated OFMSW (285 mL CH 4 STP g -1 VS added ). The modified Gompertz model adequately predicted process performance. The maximum methane production rate, R m , for ground and sieved OFMSW was 2.4 times higher than that of untreated OFMSW. The anaerobic co-digestion of different mixtures of OFMSW and LFHTC of DSS did not increase the methane yield above that of the anaerobic digestion of OFMSW alone, and no synergistic effects were observed. However, the co-digestion of both wastes at a ratio of 75% OFMSW-25% LFHTC provides a practical waste management option. The experimental results were adequately fitted to a first-order kinetic model showing a kinetic constant virtually independent of the percentage of LFHTC (0.52-0.56 d -1 ) and decreasing slightly for 100% LFHTC (0.44 d -1 ).

    In the present study, the effect of furan derivatives (furfural and 5-hydroxymethylfurfural) and phenolic compounds (vanillin and syringaldehyde) on hydrogen production from organic fraction of municipal solid waste (OFMSW) was investigated using co-culture of facultative anaerobes Enterobacter aerogenes and E. coli. The inhibitors were applied in the concentration ranges of 0.25, 0.5, 1, 2 and 5g/L each. Inhibition coefficients of phenolic compounds were higher than those of furan derivatives and vanillin exhibited maximum inhibition coefficients correspondingly lowest hydrogen yield among all inhibitors. Furfural and 5-hydroxymethylfurfural addition resulted in an average decrease of 26.99% and 37.16% in hydrogen yield respectively, while vanillin and syringaldehyde resulted in 49.40% and 42.26% average decrease in hydrogen yield respectively. Further analysis revealed that Furfural and 5-hydroxymethylfurfural were completely degraded up to concentrations of 1g/L, while vanillin and syringaldehyde were degraded completely up to the concentration of 0.5g/L. Volatile fatty acid generation decreased with inhibitors addition. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The effect of biosurfactants (surfactin and saponin) on the hydrogen production from organic fraction of municipal solid waste (OFMSW) was investigated using co-culture of facultative anaerobes Enterobacter aerogenes and E. coli. The biosurfactants were applied in the concentration ranges of 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5 and 5.0% each. Cumulative hydrogen production (P), maximum hydrogen production rate (Rmax) and lag phases (λ) were analyzed using modified Gompertz model. Results revealed that both the biosurfactants were effective in hydrogen production enhancement. The maximum cumulative hydrogen production of 743.5±14.4ml and 675.6±12.1ml and volumetric hydrogen production of 2.12L H2 /L substrate and 1.93L H2 /L substrate was recorded at 3.5% surfactin and 3.0% saponin respectively. Corresponding highest hydrogen yields were 79.2mlH 2 /gCarbo initial and 72.0mlH 2 /gCarbo initial respectively. Lag phase decreased from 12.5±2.0h at control to a minimum of 9.0±2.8h and 9.5±2.1h at 3.5% surfactin and 3.0% saponin respectively.

    We carried out a study to characterize fruit fly populations on an organic guava orchard (Psidium guajava cv. Paluma) in the municipality of Una, southern region of the state of Bahia, Brazil, using faunistic analysis of the adult fruit f y specimens captured in McPhail traps from January 2004 through March 2007. A total of 22,673 specimens of Anastrepha (15,306 females and 7,367 males) were captured. Thirteen species of Anastrepha were recorded. A. fraterculus and A. obliqua were the more frequent and dominant species, accounting for 90.1% of all females captured in the traps. A. fraterculus was the predominant species (more frequent, constant and dominant). The high value of the Simpson index (0.62) and the low values of Shannon-Wiener (0.83) and equitability (0.49) indices indicated the dominance and high frequency of A. fraterculus and A. obliqua on the guava orchard despite the presence of other fruit species as potential hosts of fruit flies.

    In the present study, the effect of heavy metals (lead, mercury, copper, and chromium) on the hydrogen production from the organic fraction of municipal solid waste (OFMSW) was investigated using co-culture of facultative anaerobes Enterobacter aerogenes and E. coli. Heavy metals were applied at concentration range of 0.5, 1, 2, 5, 10, 20, 50 and 100 mg/L. The results revealed that lead, mercury, and chromium negatively affected hydrogen production for the range of concentrations applied. Application of copper slightly enhanced hydrogen production at low concentration and resulted in the hydrogen yield of 36.0 mLH 2 /gCarbo initial with 10 mg/L copper supplementation as compared to 24.2 mLH 2 /gCarbo initial in control. However, the higher concentration of copper (>10 mg/L) declined hydrogen production. Hydrogen production inhibition potential of heavy metals can be arranged in the following increasing order: Cu 2+  metal addition. Thus, the present study reveals that the presence of heavy metals in the feedstock is detrimental for the hydrogen production. Therefore, it is essential to remove the toxic heavy metals prior to anaerobic digestion. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Full Text Available This paper develops the strategic alignment of organizational behavior through the organizations´ image, prioritization and information security practices. To this end, information security is studied based on the business requirements of confidentiality, integrity and availability by applying a tool which integrates the strategic, tactical and operational vision through the following framework: Balanced Scorecard - BSC (strategic x Control Objectives for Information and Related Technology - COBIT (tactical x International Organization for Standardization - ISO/International Electro Technical Commission - IEC27002 (operational. Another image instrument of the organization is applied in parallel with this analysis to identify and analyze performance involving profiles related to mechanistic, psychic prisons, political systems, instruments of domination, organisms, cybernetics, flux and transformation (MORGAN, 1996. Finally, a model of strategic prioritization, based on compensatory fuzzy logic (ESPIN and VANTI, 2005, is applied. The method was applied to an industrial company located in southern Brazil. The results with the application show two organizational images: "organism" and "flux and transformation ". The strategic priorities indicated a significant search for new business services and international markets. Regarding protection of information, security found the gap between "minimum" and "Reasonable" and in domain 8 (HR of standard ISO/IEC27002, considered 71% protection as "inappropriate" and "minimal" in the IT Governance context.

  15. Numerical model for a watering plan to wash out organic matter from the municipal solid waste incinerator bottom ash layer in closed system disposal facilities.

    Bottom ash from municipal solid waste incineration (MSWI) is a main type of waste that is landfilled in Japan. The long-term elution of organic matter from the MSWI bottom ash layers is a concern because maintenance and operational costs of leachate treatment facilities are high. In closed system disposal facilities (CSDFs), which have a roof to prevent rainfall from infiltrating into the waste layers, water must be supplied artificially and its quantity can be controlled. However, the quantity of water needed and how to apply it (the intensity, period and frequency) have not been clearly defined. In order to discuss an effective watering plan, this study proposes a new washout model to clarify a fundamental mechanism of total organic carbon (TOC) elution behavior from MSWI bottom ash layers. The washout model considers three phases: solid, immobile water and mobile water. The parameters, including two mass transfer coefficients of the solid-immobile water phases and immobile-mobile water phases, were determined by one-dimensional column experiments for about 2 years. The intensity, period and frequency of watering and other factors were discussed based on a numerical analysis using the above parameters. As a result, our washout model explained adequately the elution behavior of TOC from the MSWI bottom ash layer before carbonation occurred (pH approximately 8.3). The determined parameters and numerical analysis suggested that there is a possibility that the minimum amount of water needed for washing out TOC per unit weight of MSWI bottom ash layer could be determined, which depends on the two mass transfer coefficients and the depth of the MSWI bottom ash layer. Knowledge about the fundamental mechanism of the elution behavior of TOC from the MSWI bottom ash layer before carbonation occurs, clarified by this study, will help an effective watering plan in CSDFs.

  16. The Science of Nuclear Safety and Security. IAEA Backs the Work of Technical and Scientific Support Organizations in Safety and Security

    2011-01-01

    Expertise in physical protection and accounting of nuclear and other radioactive material in use, storage and transport, and the associated facilities, as well as experience in the maintenance of systems, equipment and associated software used for effective border monitoring and for radiological threat assessment, are the fundaments of safety and security. This knowledge is developed through technical and scientific support organizations (TSOs), neutral and official organizations that provide the basis for decisions and activities regarding nuclear and radiation safety. The quality of the technical and scientific expertise provided by TSOs to the nuclear industry and their contribution to effective regulatory systems are of fundamental importance. For many years, the IAEA has been supporting the work of TSOs, by helping the TSOs promote their technical competence, transparency and observance of ethical principles.

  17. Extraction of medium chain fatty acids from organic municipal waste and subsequent production of bio-based fuels.

    This paper provides an overview on investigations for a new technology to generate bio-based fuel additives from bio-waste. The investigations are taking place at the composting plant in Darmstadt-Kranichstein (Germany). The aim is to explore the potential of bio-waste as feedstock in producing different bio-based products (or bio-based fuels). For this investigation, a facultative anaerobic process is to be integrated into the normal aerobic waste treatment process for composting. The bio-waste is to be treated in four steps to produce biofuels. The first step is the facultative anaerobic treatment of the waste in a rotting box namely percolate to generate a fatty-acid rich liquid fraction. The Hydrolysis takes place in the rotting box during the waste treatment. The organic compounds are then dissolved and transferred into the waste liquid phase. Browne et al. (2013) describes the hydrolysis as an enzymatically degradation of high solid substrates to soluble products which are further degraded to volatile fatty acids (VFA). This is confirmed by analytical tests done on the liquid fraction. After the percolation, volatile and medium chain fatty acids are found in the liquid phase. Concentrations of fatty acids between 8.0 and 31.5 were detected depending on the nature of the input material. In the second step, a fermentation process will be initiated to produce additional fatty acids. Existing microorganism mass is activated to degrade the organic components that are still remaining in the percolate. After fermentation the quantity of fatty acids in four investigated reactors increased 3-5 times. While fermentation mainly non-polar fatty acids (pentanoic to octanoic acid) are build. Next to the fermentation process, a chain-elongation step is arranged by adding ethanol to the fatty acid rich percolate. While these investigations a chain-elongation of mainly fatty acids with pair numbers of carbon atoms (acetate, butanoic and hexanoic acid) are demonstrated. After

    2016-05-01

    Full Text Available The role run by a coalition of NGOs in advocating the National Security Bill aimed at encouraging the birth of national security policy to appropriate to the purpose of reform. However, until now the role of NGOs in advocating National Security Bill has not been able to encourage the authorities to reconstruct the draft of national security policy that is consistent with the objectives of security sector reform. This study is conducted to analyze the role of NGOs in the security sector reform in Indonesia, particularly through the advocacy of the National Security Bill. The method used in this study is a qualitative method. The result shows that NGOs, which are members of the KMSRK, have been running the multiple roles, such as: popularly involved in policy making, providing political education to the community, promoting or encouraging reform, and promoting the interests of the community. The study also suggests the existence of new findings of the role of NGOs, which is forming a coherent unity of interests.

    Fongsatitkul, Prayoon; Elefsiniotis, Panagiotis; Wareham, David G

    2010-09-01

    This paper describes how the degradation of the organic fraction of municipal solid waste (OFMSW) is affected through codigestion with varying amounts of return activated sludge (RAS). Solid waste that had its inorganic fraction selectively removed was mixed with RAS in ratios of 100% OFMSW, 50% OFMSW/50% RAS, and 25% OFMSW/75% RAS. The total solids (TS) concentration was held at 8% and three anaerobic digester systems treating the mixtures were held (for the first run) at a total hydraulic retention time (HRT) of 28 days. Increasing amounts of RAS did not however improve the mixture's digestability, as indicated by little change and/or a drop in the main performance indices [including percentage volatile solids (VS) removal and specific gas production]. The optimum ratio in this research therefore appeared to be 100% OFMSW with an associated 85.1 ± 0.6% VS removal and 0.72 ± 0.01 L total gas g(- 1) VS. In the second run, the effect of increasing percentage of TS (8, 12% and 15%) at a system HRT of 28 days was observed to yield no improvement in the main performance indices (i.e. percentage VS removal and specific gas production). Finally, during the third run, variations in the total system HRT were investigated at an 8% TS, again using 100% OFMSW. Of the HRTs explored (23, 28 and 33 days), the longest HRT yielded the best performance overall, particularly in terms of specific gas production (0.77 ± 0.01 L total gas g(-1) VS).

  7. The effect of ultrasonic pretreatment on biogas generation yield from organic fraction of municipal solid waste under medium solids concentration circumstance

    2016-01-01

    Highlights: • Ultrasonic pretreatment improved biogas yields at lower TS content samples. • Time of ultrasonication was significantly effective on maximum biogas yields. • Ultrasonic pretreatment can cause the release of TVFA content before digestion. • Specific energy between 5000 kJ/kg TS and 10,000 kJ/kg TS improved biogas yields. - Abstract: Hydrolysis is the most rate limiting step in almost all anaerobic digestion systems. To tackle long time duration, ultrasonic pretreatment proved that it can effectively improve biogas yield efficiency by effecting on soluble particles. In this study, the effect of three different ultrasonic power densities (0.2 W/mL, 0.4 W/mL and 0.6 W/mL) at three different times (10 min, 20 min and 30 min) on biogas yield of organic fraction of municipal solid waste (OFMSW) at three different total solid content (6%, 8% and 10%) were analyzed. Results showed significant (p < 0.01) effect of both sonication density and time of sonication on biogas final yield and biogas yield after 72 h digestion with the 6% TS content. Parameters like specific energy input and total volatile fatty acid (TVFA) content were also evaluated to find the best sonication treatments for OFMSW. For lower TS contents (6% and 8%), sonication treatment significantly (p < 0.01) increased TVFA concentration before digesting. It is also proved that specific energy input between 5000 kJ/kg TS and 10,000 kJ/kg TS can effectively increase the biogas yields, especially for 6% TS content, and caused maximum biogas yield produced after 72 h of digestion.

    The objective of this work was to compare the performance of two laboratory-scale, mesophilic systems aiming at the anaerobic digestion of the organic fraction of municipal solid wastes (OFMSW). The first system consisted of two coupled reactors packed with OFMSW (PBR1.1-PBR1.2) and the second system consisted of an upflow anaerobic sludge bed reactor (UASB) coupled to a packed reactor (UASB2.1-PBR2.2). For the start-up phase, both reactors PBR 1.1 and the UASB 2.1 (also called leading reactors) were inoculated with a mixture of non-anaerobic inocula and worked with leachate and effluent full recirculation, respectively. Once a full methanogenic regime was achieved in the leading reactors, their effluents were fed to the fresh-packed reactors PBR1.2 and PBR2.2, respectively. The leading PBR 1.1 reached its full methanogenic regime after 118 days (Tm, time to achieve methanogenesis) whereas the other leading UASB 2.1 reactor reached its full methanogenesis regime after only 34 days. After coupling the leading reactors to the corresponding packed reactors, it was found that both coupled anaerobic systems showed similar performances regarding the degradation of the OFMSW. Removal efficiencies of volatile solids and cellulose and the methane pseudo-yield were 85.95%, 80.88% and 0.109 NL CH4 g(-1) VS(fed) in the PBR-PBR system; and 88.75%, 82.61% and 0.115 NL CH4 g(-1) VS(fed0 in the UASB-PBR system [NL, normalized litre (273 degrees K, 1 ata basis)]. Yet, the second system UASB-PBR system showed a faster overall start-up.

    Full Text Available The increase in greenhouse gas emissions from anthropogenic sources has resulted in climate change, which affects all living beings. Coffee (Coffea arabica L. plantations, in monoculture or together with timber species such as salmwood (Cordia alliodora, mitigate climate change due to fixation of atmospheric CO2 that is deposited in biomass and soils. This study was carried out in the municipality of Líbano, Tolima, Colombia with the objective of defining which of the following coffee production systems store more soil organic carbon (SOC: 1 monoculture, 2 agroforestry systems (AFS with salmwood, and 3 AFS with plantain. Farms with those systems that are the most dominant in the study zone were selected. From each system, five repetitions were identified to be analyzed with a completely randomized design. In each plot or repetition, five samples for bulk density (BD using the cylinder method and a composite sample for concentration of SOC were taken and analyzed using the Walkley and Black approach. The systems of production did not significantly (p > 0.05 affect either the BD or the concentration of SOC. However, AFS with plantain tended to have less BD than monoculture and AFS with salmwood (0.83 ± 0.03 vs 0.88 ± 0.03 vs 0.92 ± 0.04 g·cm-3, respectively. These systems of production stored between 50 and 54 t·ha-1 of SOC in the top 30 cm, which indicates their capacity for climate change mitigation.

    New waste management programs are currently aimed at developing alternative treatment technologies such as mechanical-biological treatment (MBT) and composting plants. However, there is still a high uncertainty concerning the chemical and microbiological risks for human health, not only for workers of these facilities, but also for the population living in the neighborhood. A new MBT plant is planned to be constructed adjacently to a municipal solid waste incinerator (MSWI) in Tarragona (Catalonia, Spain). In order to evaluate its potential impact and to differentiate the impacts of MSWI from those of the MBT when the latter is operative, a pre-operational survey was initiated by determining the concentrations of 20 volatile organic compounds (VOCs) and bioaerosols (total bacteria, Gram-negative bacteria, fungi and Aspergillus fumigatus) in airborne samples around the MSWI. The results indicated that the current concentrations of bioaerosols (ranges: 382-3882, 18-790, 44-926, and 3 for fungi at 25 deg. C, fungi at 37 deg. C, total bacteria, and Gram-negative bacteria, respectively) and VOCs (ranging from 0.9 to 121.2 μg/m 3 ) are very low in comparison to reported levels in indoor and outdoor air in composting and MBT plants, as well in urban and industrial zones. With the exception of total bacteria, no correlations were observed between the environmental concentrations of biological agents and the direction/distance from the facility. However, total bacteria presented significantly higher levels downwind. Moreover, a non-significant increase of VOCs was detected in sites closer to the incinerator, which means that the MSWI could have a very minor impact on the surrounding environment.

    Directory of Open Access Journals (Sweden)

    Myeonggil Choi

    2015-08-01

    Full Text Available Cloud computing has made it possible for private companies to make rapid changes in their computing environments. However, in the public sector, security issues hinder institutions from adopting cloud computing. To solve these security challenges, in this paper, we propose a methodology for information security management, which quantitatively classifies the importance of information in cloud systems in the public sector. In this study, we adopt a Delphi approach to establish the classification criteria of the proposed methodology in an objective and systematic manner. Further, through a case study of a public corporation, we try to validate the usefulness of the proposed methodology. The results of this study will help public institutions to consider introducing cloud computing and to manage cloud systems effectively and securely.

  19. Investigation of the radiological impact of naturally occurring radionuclides from the usage of phosphate and organic fertilizers on farmlands in the New Juaben Municipality of Ghana

    Gyenfie, J. A.

    2015-07-01

    The radiological impact of naturally occurring radioactive materials (NORMs) from the usage of phosphate and organic fertilizers in the New Juaben Municipality of Ghana was investigated. The activity concentrations of 226 Ra, 232 Th and 40 K were measured in seven (7) widely used phosphate and organic fertilizers using gamma spectroscopy. The activity concentrations were found to be 32.10±2.60 Bq/kg, 12.20±1.60 Bq/kg and 3005.50±68.80 Bq/kg respectively. The radioactivity level index (Iγ ) which gives an estimate of the level of risk associated with natural radionuclides in specific material was found to be higher than the recommended limit of one (1) in some of the fertilizer samples collected from storage. The storage also recorded a relatively high dose rates (ranging from 96-624 μSv/a) compared to the surrounding background (ranging from 109-241 μSv/a) suggesting that the storage of large quantities of these fertilizers can lead to a possible increase in the dose rates. The mean activity concentrations of 226 Ra, 232 Th and 40 K in cultivated (fertilized) soils were found to be 12.50±3.30 Bq/kg, 10.60 ± 2.80 Bq/kg and 206.0 ± 30.2 Bq/kg respectively. These values were relatively higher than those found in their respective virgin (unfertilized) soils ( 226 Ra- 9.0±1.7 Bq/kg; 232 Th - 8.10±1.70 Bq/kg; and 40 K-139.0±13.3 Bq/kg). This might be considered as an indication that the use of fertilizers to increase soil fertility enhances the level of 226 Ra, 232 Th and 40 K in agricultural soils. The averages of other risk indices such as radium equivalent, the absorbed dose rate in air at 1m above the ground, the mean outdoor annual effective dose and the external hazard index estimated for the cultivated soils were found to be higher than their corresponding virgin soils but generally lower than the world averages. Therefore, the radiological impact associated with NORMs in the cultivated lands as a result of the application of fertilizers is expected to

    In light of the exceptional circumstances that arose from hosting the Olympic Games in Athens in 2004 and from recent terrorist events internationally, Greece attributes the highest priority to security issues. According to its statutory role, the Greek Atomic Energy Commission is responsible for emergency preparedness and response in case of nuclear and radiological events, and advises the Government on the measures and interventions necessary to protect the public. In this context, the Commission participated in the Nuclear, Radiological, Biological, and Chemical Threat National Emergency Plan, specially developed for the Olympic Games, and coordinated by the Olympic Games Security Division. The objective of this paper is to share the experience gained during the organization of the Olympic Games and to present the nuclear security program implemented prior to, during, and beyond the Games, in order to prevent, detect, assess, and respond to the threat of nuclear terrorism. This program adopted a multi-area coverage of nuclear security, including physical protection of nuclear and radiological facilities, prevention of smuggling of radioactive materials through borders, prevention of dispersion of these materials into the Olympic venues, enhancement of emergency preparedness and response to radiological events, upgrading of the technical infrastructure, establishment of new procedures for assessing the threat and responding to radiological incidents, and training personnel belonging to several organizations involved in the National Emergency Response Plan. Finally, the close cooperation of Greek Authorities with the International Atomic Energy Agency and the U.S. Department of Energy, under the coordination of the Greek Atomic Energy Commission, is also discussed.

  12. Influence of different flow conditions on the occurrence and behavior of potentially hazardous organic xenobiotics in the influent and effluent of a municipal sewage treatment plant in Germany: an effect-directed approach

    2012-12-15

    Flow conditions in the sewer systems are particularly important for the chemical and toxicological characteristics of raw and treated wastewater. Nevertheless, this topic has not been thoroughly investigated to date. In this study, composite wastewater samples were taken daily from the influent and effluent of a municipal sewage treatment plant. Polarity-based fractionation of the samples was carried out through sequential solid phase extractions. Biological testing of single and recombinant fractions was performed using bioluminescence inhibition assay according to DIN EN ISO 11348-2. Selected compounds (pharmaceuticals and polycyclic aromatic hydrocarbons) were also included in the chemical analysis by liquid chromatography coupled with tandem mass spectrometry and gas chromatography coupled with mass spectrometry. By analyzing different flow conditions, this study clarifies how these fractions contribute to the total toxicity of organic substances in wastewater. Additionally, it demonstrates the extent to which the potentially hazardous effects of the fractions can be reduced at the examined sewage treatment plant. Summarizing, medium to highly polar organic compounds were particularly relevant for the total toxicity of organic xenobiotics. For rising wastewater flow under wet weather conditions, we observed a significant decrease in the overall toxicity of the organic pollutants and specifically in the toxic effects of the moderately polar fraction 2. The results provide the starting point for an important risk assessment regarding the occurrence and behavior of potentially toxic xenobiotics by differentiated polarity in municipal wastewater for varying flow conditions.

    Technical progress is moving more and more quickly and the systems thus produced are so complex and have become so unclear to the individual that he can no longer estimate the consequences: Faith in progress has given way to deep mistrust. Companies have adjusted to this change in consciousness. An interesting tendency can be identified: technical security is already available - now the organization of security has become an important objective for companies. The key message of the book is: If outworn technical systems are no longer adequate, the organization must be thoroughly overhauled. Five chapters deal with the following themes: organization as an aspect of society; risk control; aspects of security; is there security in ADP; the broader concept of security. (orig./HP) [de

Some of their archaeological remains make the study of aspects of the juridical and administrative evolution of the municipium possible: municipal institutions, religious forms, social structures and traces of the indigenous people, principally in the first two centuries of the Empire. | Sobre el emplazamiento del Cerro de San Juan del Viso se han encontrado huellas arqueológicas que permiten situar allí el antiguo emplazamiento de la ciudad de Complutum que, probablemente en época flavia, y al amparo del paso de personas y mercancías por el valle, se trasladó a su definitivo emplazamiento en el llano, junto al río Henares. Son abundantes los testimonios arqueológicos en la ciudad y sus alrededores, aunque escasos los que permitan seguir la evolución jurídica y administrativa del municipio. Aún así, es posible rastrear sus instituciones municipales, las formas religiosas, la estructura social y la escasa huella indígena en la ciudad, principalmente a lo largo de los dos primeros siglos del Imperio.

    Municipalities are directly affected by the liberalization of the energy markets. Because they all consume or even produce energy, whether it be for their own consumption or to resell it, they often distribute gas, electricity or heat, they plan urban areas and organize the energy networks on their territory, while in addition citizens expect municipalities to inform them and even protect them against the possible excesses of energy salesmen. Elected representatives administrations, local agencies, municipal companies, citizens' associations etc., all have to innovate. This supplement to Energie-Cites INFO is intended to provide you with practical information and further analyses of the liberalization process. (authors)

    Polona Kambič

    2014-09-01

    Full Text Available Research Question (RQ: Do knowledge and skills of the director of municipal administration have an influence on employee satisfaction? Purpose: To research the knowledge and skills, a leader needs to guide employees towards reaching a work place satisfaction and consequently towards higher effectiveness of the organization. Method: A case study on a smaller municipal administration based on an interview with the director of municipal administration on development of knowledge and skills; a questionnaire for determining leadership abilities and a questionnaire for measuring work satisfaction of employees in municipal administration. Results: The influence of knowledge and skills of the director of municipal administration on employee satisfaction. Organization: Organization that strives for success needs to devote special attention to people management. Satisfied employees are successful in their work assignments and consequently contribute to effectiveness of the organization. Society: The purpose of municipal administration is to fulfill the needs of its citizens as much as possible. A quality service for citizens as service users can only be provided by satisfied employees in the municipal administration. Originality: In the municipal administration of the studied municipality a research study on the influence of knowledge and skills of the leader on employee satisfaction has not been carried out yet, so this will serve as grounds for improvement of organizational climate in the organization. Limitations/further research: The director of municipal administration is the author’s subordinate. The municipal administration has only eight employees, which is a limited sample size even though all employees participated in the research study. In the future it would be wise to conduct a study with all three municipal administrations of the Bela krajina region, as this would provide a clearer picture of employee satisfaction in the municipalities of

    Full Text Available Soy occupies the largest area of agricultural land in Brazil, spreading from southern states to the Amazon region. Soy is also the most important agricultural commodity among Brazilian exports affecting food security and land use nationally and internationally. Here we pose the question of whether soy expansion affects only economic growth or whether it also boosts socioeconomic development, fostering education and health improvements in Brazilian municipalities where it is planted. To achieve this objective, we divided more than 5000 municipalities into two groups: those with >300 ha of soy (soy municipalities and those with <300 ha of soy (non-soy municipalities. We compared the Human Development Index (HDI and the Gini coefficient for income for these two groups of municipalities in 1991, 2000, and 2010. We made such comparison at the municipality level for the whole country, but we also grouped the municipalities by major geographical regions and states. We found that the HDI was higher in soy municipalities, especially in the agricultural frontier. That effect was not so clear in more consolidated agricultural regions of the country. Soy municipalities also had a higher Gini coefficient for income than non-soy municipalities. We concluded that soy could be considered a precursor of socioeconomic development under certain conditions; however, it also tends to be associated with an increase in income inequality, especially in the agricultural frontier.

    The mass and biogas potentials of organic municipal and industrial solid wastes, as well as of wastes harvested on public grounds, have been determined. The mass potential was found to be around 285`000 tons of digestible organic matter per year. By digesting all this matter, about 130`000`000 m{sup 3} of biogas or 3 PJ of energy could be generated yearly. The practical realizable potential is estimated to be nearly 2 PJ/a, including the savings by substituting the energy needed nowadays for the importation of peat and for the production of artificial fertilizers. Considering the fact, that the incineration of organic wastes costs more than biological treatment, the potential is relatively easy to realize. More than 50% of the humus losses of Swiss soils could be compensated by the application of digestion and composting technology. The different technologies for anaerobic digestion of solid organic wastes are compared: the thermophilic, one-stage digestion seems to be further advanced in development than mesophilic two-stage digestion. Co-digestion of sludges of municipal waste water treatment plants and solid organic wastes may be advantageous for rural areas. An appropriate marketing strategy for the application of the solid product, however, has to be looked at. Because the two-stage process seems to have some advantages regarding rate of organic matter breakdown, product quality and hygienic conditions, a mesophilic two-stage experimental plant has been constructed. The results of the first experiment of a simple combination of a percolated hydrolytic step with a pulsating, dynamic anaerobic filter ar presented. Data on the quality of the solid product from anaerobic digestion of biogenic solid wastes and an economic comparison of composting vs. digestion are given. (author) 9 figs., 11 tabs., 75 refs.

  6. Introduction to the Asian Energy Security project: Project organization and methodologies

    2011-01-01

    The spectacular recent economic growth in the Asia-Pacific region in general, and in many of the economies of Northeast Asia in particular, has spurred a vast expansion in the need for energy services, and an expansion in the demand for the fuels that help to supply these services. Future projections suggest that the growth of fossil fuel use in Northeast Asia, especially in China, will have major consequences for financial and fuel markets and pollution both regionally and globally. Before the project described in this paper was initiated, there was no ongoing forum for energy experts from all of the countries of the region to meet, informally and in an unofficial capacity, to discuss openly and in a targeted fashion the energy situations in their countries, and to work together to evaluate the energy efficiency costs and benefits of different ways of meeting regional demand. The Asian Energy Security (AES) project provides such a forum, and as such constitutes a unique resource in the engagement of the countries of Northeast Asia on the topic of energy security.

    A municipal landfill causes atmospheric pollution by the emission of trace volatile organic compounds (VOCs) that are harmful for health and environment. Beyond the adsorption technique on sorbent tubes followed by solvent extraction and GC/MS analysis in the laboratory, a pre-concentrator-thermodesorption /micro-gas chromatograph coupling was developed for on-site monitoring of trace VOCs. To evaluate the environmental impact of this traces various studies were realized: 'Study of the emission of VOCs from landfill cells in use', 'Study of the formation of VOCs from a pilot-scale municipal landfill', 'Study of the dispersion of VOCs from a municipal landfill'. All the results permitted a closer appraisal of the emission and dispersion phenomena of VOCs from a municipal landfill. (author)

    The article present a review on own experimental and some published data which are related with the gold leaching. It is well-known that the most common and usual process of the leaching with cyanide can be dangerous, needs a great water consumption, and additional costs for remediation of the poisoned and toxic sites. The experimental data described production of poythionates which are not toxic but perspective for the prosperous gold leaching. The paper dedicated to the safe gold leaching with thiosulfates and organic salts of polythionic acids (organic base polythionates). The method of production of these polythionates based on the Smolyaninov reaction is described in stages and in details for the first time. Possible application of the polythionates application in the gold leaching is discussed and its advantages are compared with the gold leaching by cyanation.

  2. Global Health Security Demands a Strong International Health Regulations Treaty and Leadership From a Highly Resourced World Health Organization.

    Science.gov (United States)

    Burkle, Frederick M

    2015-10-01

    If the Ebola tragedy of West Africa has taught us anything, it should be that the 2005 International Health Regulations (IHR) Treaty, which gave unprecedented authority to the World Health Organization (WHO) to provide global public health security during public health emergencies of international concern, has fallen severely short of its original goal. After encouraging successes with the 2003 severe acute respiratory syndrome (SARS) pandemic, the intent of the legally binding Treaty to improve the capacity of all countries to detect, assess, notify, and respond to public health threats has shamefully lapsed. Despite the granting of 2-year extensions in 2012 to countries to meet core surveillance and response requirements, less than 20% of countries have complied. Today it is not realistic to expect that these gaps will be solved or narrowed in the foreseeable future by the IHR or the WHO alone under current provisions. The unfortunate failures that culminated in an inadequate response to the Ebola epidemic in West Africa are multifactorial, including funding, staffing, and poor leadership decisions, but all are reversible. A rush by the Global Health Security Agenda partners to fill critical gaps in administrative and operational areas has been crucial in the short term, but questions remain as to the real priorities of the G20 as time elapses and critical gaps in public health protections and infrastructure take precedence over the economic and security needs of the developed world. The response from the Global Outbreak Alert and Response Network and foreign medical teams to Ebola proved indispensable to global health security, but both deserve stronger strategic capacity support and institutional status under the WHO leadership granted by the IHR Treaty. Treaties are the most successful means the world has in preventing, preparing for, and controlling epidemics in an increasingly globalized world. Other options are not sustainable. Given the gravity of ongoing

    The organic carbon of biosolids from civil wastewater treatment plants binds persistent organic pollutants (POPs), such as polychlorodibenzo -dioxins and -furans (PCDD/Fs), dioxin and non-dioxin -like polychlorobiphenyls (DL and NDL-PCBs), polybrominated diphenyl ethers (PBDEs), and perfluorooctane sulfonic acid (PFOS). The use of such biosolids, derived digestates and composts as top soil improvers (TSIs) may transfer POPs into the food chain. We evaluated the potential carry-over of main bioavailable congeners from amended soil-to-milk of extensive farmed sheep. Such estimates were compared with regulatory limits (food security) and human intakes (food safety). The prediction model was based on farming practices, flocks soil intake, POPs toxicokinetics, and dairy products intake in children, of the Mediterranean area. TSI contamination ranged between 0.20-113 ng WHO-TEQ/kg dry matter for PCDD/Fs and DL-PCBs (N = 56), 3.40-616 μg/kg for ∑6 NDL-PCBs (N = 38), 0.06-17.2 and 0.12-22.3 μg/kg for BDE no. 47 and no. 99, 0.872-89.50 μg/kg for PFOS (N = 27). For a 360 g/head/day soil intake of a sheep with an average milk yield of 2.0 kg at 6.5% of fat percentage, estimated soil quality standards supporting milk safety and security were 0.75 and 4.0 ng WHO-TEQ/kg for PCDD/Fs and DL-PCBs, and 3.75 and 29.2 μg/kg for ∑6 NDL-PCBs, respectively. The possibility to use low-contaminated TSIs to maximize agriculture benefits and if the case, to progressively mitigate highly contaminated soils is discussed.

KFOR’s image has come to the fore because it affects the mission success and decisions about its existence in Kosovo. The image has two components, functional and emotional: Military symbols and uniforms of NATO (KFOR are functional and emotional relations of countries with Kosovo Security Forces (KSF members are emotional part. In this research; the main objective is finding out the effects that shape KFOR image. Sublevel objectives are the effects of Kosovo’s “connections”, KSF “personal links” and “perceived mission success” with KFOR member states in KFOR image. To study these effect 3 hypothesis are formed and empirical research is done with KSF members to get a foundation of emotional relationship which affects country image. Evaluating of questionnaires with linear regression, correlation and factor analysis, besides the important effects of ethnocentrism and patriotism, military personnel relations formed by countries military involvement and activities found as predictor factors in KFOR image. As a matter of course these base components of emotions about the image will enlighten future literature about building an organizational image.

    For best results, computer security should be engineered into a system during its development rather than being appended later on. This paper addresses the implementation of computer security in eight stages through the life cycle of the system; starting with the definition of security policies and ending with continuing support for the security aspects of the system throughout its operational life cycle. Security policy is addressed relative to successive decomposition of security objectives (through policy, standard, and control stages) into system security requirements. This is followed by a discussion of computer security organization and responsibilities. Next the paper directs itself to analysis and management of security-related risks, followed by discussion of design and development of the system itself. Discussion of security test and evaluation preparations, and approval to operate (certification and accreditation), is followed by discussion of computer security training for users is followed by coverage of life cycle support for the security of the system

    Full Text Available Abstract - Business Organizations and Government unequivocally relies on upon data to deal with their business operations. The most unfavorable impact on association is disappointment of friendship, goodness, trustworthiness, legitimacy and probability of data and administrations. There is an approach to ensure data and to deal with the IT framework's Security inside association. Each time the new innovation is made, it presents some new difficulties for the insurance of information and data. To secure the information and data in association is imperative on the grounds that association nowadays inside and remotely joined with systems of IT frameworks. IT structures are inclined to dissatisfaction and security infringement because of slips and vulnerabilities. These slips and vulnerabilities can be brought on by different variables, for example, quickly creating headway, human slip, poor key particulars, poor movement schedules or censuring the threat. Likewise, framework changes, new deserts and new strikes are a huge piece of the time displayed, which helpers augmented vulnerabilities, disappointments and security infringement all through the IT structure life cycle. The business went to the confirmation that it is essentially difficult to ensure a slip free, risk free and secure IT structure in perspective of the disfigurement of the disavowing security parts, human pass or oversight, and part or supplies frustration. Totally secure IT frameworks don't exist; just those in which the holders may have changing degrees of certainty that security needs of a framework are fulfilled do. The key viewpoints identified with security of data outlining are examined in this paper. From the start, the paper recommends pertinent legitimate structure and their duties including open association obligation, and afterward it returns to present and future time, system limits, structure security in business division.

    Full text of publication follows. The decommissioning of the Vandellos-I nuclear power plant was a big challenge for the host community of Vandellos i l'Hospitalet de l'Infant and the close-by region. Closing down of the facility resulted in a rise of unemployment and a decrease of municipal income. The public was concerned with three issues: safety, transparency and information about the decommissioning, and economic future. Therefore, from the very beginning, municipal governments entered into negotiations with ENRESA on socio-economic benefits, including local employment in dismantling activities, and other types of financial and non-financial compensation. The ADE business association, i.e. a network of business organisations was created that guided the allotment of work to local firms. To satisfy public demand, local municipalities focused on the triad of safety, dialogue and local development, considered the three 'pillars of trust'. A Municipal Monitoring Commission was created, made up of representatives of affected municipalities, the regional government, the ADE business association, trade unions, the local university, the NPP management and ENRESA to monitor the dismantling process and regularly inform the local public. Items that were handled by this Commission included: - Work process monitoring. - Workers. - Materials Control. - Conventional and radioactive or contaminated waste management. - Emanation waste management (liquid and gas) - Safety (training and accidents). - Surveillance (radiological and environmental: dust, noise). - Effects. - Fulfillment of agreed conditions. A number of communication tools and channels were used, e.g., public information meetings, an information centre, the municipal magazine, the municipal radio station, and meetings with representatives of the local press. Particularly innovative was the idea to ask academics from the University of Tarragona to help with 'translating' technical information into language that could

    Droughts statistically exceed all other natural disasters in spatio-temporal extent, number of people affected or financial loss. Triggered by crop failure, food insecurity is a major manifestation of agricultural drought and water scarcity. However, other socio-economic precursors, such as chronically low levels of disaster preparedness, hampered access to food security or a lack of social safety nets are equally important factors. Consequently, this study is focused on two complementary developments - a new satellite-derived agricultural drought index and a mobile phone application. The Combined Drought Index (CDI) is enhanced by replacing field measurements of temperature and rainfall modelled/assimilated data. The vegetation component is replaced by a smoothed NDVI dataset. A soil moisture component is introduced to close the gap between rainfall deficiencies and the first visible impacts of atmospheric anomalies on vegetation. The mobile phone application enables the validation of drought index outputs and gives aid organizations an opportunity to increase the speed of socio-economic vulnerability assessments. Supported by Doctors without Borders (MSF) this approach aims at decreasing uncertainties in decision-making via a more holistic risk framework.

  1. Types, risks and market of municipal bonds

    2012-01-01

    Full Text Available Municipal bonds are issued by cities, municipalities or other local communities in order to quickly raise funds to cover current budget deficits, finish infrastructure projects for production and distribution of thermal energy, improve water supply, road construction, sports and recreation centers, schools or to fund such projects on more favorable terms than to borrow from banks. In this manner, necessary conditions are created for faster development of the real sector. The aim of this study is to evaluate the importance, possibilities and effects of the bond issue in the Republika Srpska aimed at securing funding for and development of local communities. Good examples that local government bonds enhance community development include capital markets in countries that have made the transition from the socialist system design, similar to the market of the Republika Srpska, like the Polish, Slovakian, Hungarian and Croatian markets. Issues of municipal bonds in the Republika Srpska succeeded mostly due to the workings of Investment-Development Bank of RS. However, it certainly shows that further high-quality municipal bonds could attract more interest from various institutional investors, especially mutual funds and insurance companies, and investors who are more risk-averse will be able to familiarize and inform themselves with the functioning of capital markets. In this manner, our capital market would confirm its essential role and thus become a generator of overall economic development of the Republika Srpska because it would enable more efficient collection and allocation of capital resources.

  6. Challenges Faced by Regulators and Technical, Scientific and Support Organizations (TSOs) in Enhancing Nuclear Safety and Security

    2011-01-01

    Renewed interest in new reactor build programmes, not only in countries with already established nuclear programmes but also in many other countries with limited or no workforce experienced in the design, licensing, construction and operation of nuclear power plants, has resulted in a need for technical, scientific and support organizations (TSOs) to support regulatory bodies in carrying out their mandated responsibilities. The primary function of a regulatory body, such as the Federal Authority for Nuclear Regulation (FANR) in the United Arab Emirates (UAE), is to regulate the safe use of nuclear facilities and radioactive material for peaceful civilian purposes. In so doing, the regulatory body needs to provide a clear and focused approach to: safety, security and safeguards for licensing; inspection and enforcement of reactor design; construction; commissioning; operation; decommissioning; nuclear waste management activities; and the use, possession or transfer of special nuclear materials and activities within the country. Accomplishing this goal requires a highly educated, multidisciplinary, diverse workforce with significant work experience. Recognizing that it takes several decades and a lot of resources to achieve self-sufficiency, many countries, particularly emergent nuclear countries, would have to rely on TSOs to start their programmes and to carry out their oversight responsibilities. Towards that end, FANR is working closely with international counterparts, the International Atomic Energy Agency and TSOs to exchange information, expertise, industry experience and ongoing research to ensure that high levels of safety, security and safeguards are established and maintained in reactor design and operation throughout the life of the facility, and that special nuclear material within the UAE is properly documented and controlled, is not stolen, lost or diverted to any illicit or non-peaceful activities, and does not pose unreasonable radiological risk due

  9. Defining Information Security.

    Science.gov (United States)

    Lundgren, Björn; Möller, Niklas

    2017-11-15

    This article proposes a new definition of information security, the 'Appropriate Access' definition. Apart from providing the basic criteria for a definition-correct demarcation and meaning concerning the state of security-it also aims at being a definition suitable for any information security perspective. As such, it bridges the conceptual divide between so-called 'soft issues' of information security (those including, e.g., humans, organizations, culture, ethics, policies, and law) and more technical issues. Because of this it is also suitable for various analytical purposes, such as analysing possible security breaches, or for studying conflicting attitudes on security in an organization. The need for a new definition is demonstrated by pointing to a number of problems for the standard definition type of information security-the so-called CIA definition. Besides being too broad as well as too narrow, it cannot properly handle the soft issues of information security, nor recognize the contextual and normative nature of security.

    Linlin, Wu; Xuan, Zhao; Meng, Zhang

    2011-04-01

    In the paper the combination process of ozonation, slow sand filtration (SSF) and nanofiltration (NF) was investigated with respect to dissolved organic matter (DOM) removal as high quality pre-treatment option for artificial groundwater recharge. With the help of ozonation leading to breakdown of the large organic molecules, SSF preferentially removes soluble microbial by-product-like substances and DOM with molecular weight (MW) less than 1.0 kDa. NF, however, removes aromatic, humic acid-like and fulvic acid-like substances efficiently and specially removes DOM with MW above 1.0 kDa. The residual DOM of the membrane permeate is dominated by small organics with MW 500 Da, which can be further reduced by the aquifer treatment, despite of the very low concentration. Consequently, the O(3)/SSF/NF system offers a complementary process in DOM removal. Dissolved organic carbon (DOC) and trihalomethane formation potential (THMFP) can be reduced from 6.5±1.1 to 0.7±0.3 mg L(-1) and from 267±24 to 52±6 μg L(-1), respectively. The very low DOC concentration of 0.6±0.2 mg L(-1) and THMFP of 44±4 μg L(-1) can be reached after the aquifer treatment. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Extracellular enzymes offer active catalysis for hydrolysis of organic solid wastes in anaerobic digestion. To evidence the quantitative significance of hydrolytic enzyme activities for major waste components, track studies of thermophilic and mesophilic anaerobic sequencing-batch reactors (TASBR and MASBR) were conducted using a co-substrate of real organic wastes. During 1day batch cycle, TASBR showed higher amylase activity for carbohydrate (46%), protease activity for proteins (270%), and lipase activity for lipids (19%) than MASBR. In particular, the track study of protease identified that thermophilic anaerobes degraded protein polymers much more rapidly. Results revealed that differences in enzyme activities eventually affected acidogenic and methanogenic performances. It was demonstrated that the superior nature of enzymatic capability at thermophilic condition led to successive high-rate acidogenesis and 32% higher CH(4) recovery. Consequently, these results evidence that the coupling thermophilic digestion with sequencing-batch operation is a viable option to promote enzymatic hydrolysis of organic particulates.

    2018-03-01

    Solid waste production is rapidly increasing in Bangladesh and landfill leachate is the consequence of the decomposition of this waste. These leachates contain heavy metals and significant amount of dissolved organic matter (DOM). DOM is known to have considerable role in heavy metals speciation. Hence, it is important to characterize DOM/leachate and evaluate toxic metals binding affinity of DOM. The objectives of this study were to characterize the DOM in landfill leachate through physico-chemical and optical analyses and to investigate the toxic metals (Ni2+, Pb2+ and Hg2+) binding affinity of three different ages (fresh sample L-1, young sample L-2 and mature sample L-3) DOM samples. Results suggested that leachate is a potential pollutant which contained very high organic pollutant load. Conditional stability constant (Log K) and percentages of fluorophores that correspond to metal binding (% f) values indicated that young DOM sample (L-2) had the highest binding affinity to all the three metals ions. In general, DOM samples showed the following order affinity to the metal ions; Ni2+ binding affinity: L-2 > L-3 > L-1, Pb2+ binding affinity: L-2 > L-3 > L-1 and Hg2+ binding affinity: L-2 > L-1 > L-3.

    The problem of fossil fuels dependency is being addressed through sustainable bio-fuels and bio-products production worldwide. At the base of this bio-based economy there is the efficient use of biomass as non-virgin feedstock. Through acidogenic fermentation, organic waste can be valorised in order to obtain several precursors to be used for bio-plastic production. Some investigations have been done but there is still a lack of knowledge that must be filled before moving to effective full scale plants. Acidogenic fermentation batch tests were performed using food waste (FW) and cheese whey (CW) as substrates. Effects of nine different combinations of substrate to inoculum (S/I) ratio (2, 4, and 6) and initial pH (5, 7, and 9) were investigated for metabolites (acetate, butyrate, propionate, valerate, lactate, and ethanol) productions. Results showed that the most abundant metabolites deriving from FW fermentation were butyrate and acetate, mainly influenced by the S/I ratio (acetate and butyrate maximum productions of 21.4 and 34.5g/L, respectively, at S/I=6). Instead, when dealing with CW, lactate was the dominant metabolite significantly correlated with pH (lactate maximum production of 15.7g/L at pH = 9). Copyright © 2017 Elsevier Ltd.

    The aim of this study was to evaluate the feasibility of treating the kitchen food waste (FW) jointly with urban wastewater (WW) in a wastewater treatment plant (WWTP) by anaerobic membrane technology (AnMBR). The experience was carried out in six different periods in an AnMBR pilot-plant for a total of 536days, varying the SRT, HRT and the food waste penetration factor (PF) of food waste disposers. The results showed increased methane production of up to 190% at 70days SRT, 24h HRT and 80% PF, compared with WW treatment only. FW COD and biodegradability were higher than in WW, so that the incorporation of FW into the treatment increases the organic load and the methane production and reduces sludge production (0.142 vs 0.614kgVSSkgremovedCOD -1 , at 70days SRT, 24h HRT and 80% PF, as compared to WW treatment only).

    Current scholarly understanding of information security regulation in the United States is limited. Several competing mechanisms exist, many of which are untested in the courts and before state regulators, and new mechanisms are being proposed on a regular basis. Perhaps of even greater concern, the pace at which technology and threats change far…
