  9. Basic principles for regulating nuclear activities

    International Nuclear Information System (INIS)

    1996-03-01

    The AECB has developed as its mission statement: 'To ensure that the use of nuclear energy in Canada does not pose undue risk to health, safety, security and the environment'. This report proposes eleven qualitative principles for regulating nuclear activities whose achievement would satisfy the broad policy enunciated in the statement. They would further provide a basis for the specific regulatory requirements expressed by the AECB in its Regulations and other documents. They would thus represent a connecting link between the policy enunciated in the mission statement and the requirements. The proposed principles are largely concerned with how the allowable risk should be set for members of the public, for industry workers, for society as a whole, and for the environment. In making these recommendations the risks from normal operation of the licensed facility and those from a possible serious accident are considered separately. The distribution of risk between geographic communities and between generations is also addressed in the proposed principles. These are listed in the final section of the report. 23 refs

  14. Control: Why, when and how? Some general principles of state control presented on the example of disqualification from performing commercial activities pursuant to § 35 of the German Trade, Commerce and Industry Regulation Act

    Directory of Open Access Journals (Sweden)

    Pürner Stefan

    2016-01-01

    Full Text Available This paper deals with issues relating to state control and state reaction to breaches of the rules discovered, using the example of Section 35 of the German Trade, Commerce and Industry Regulation Act (§ 35 Gewerbeordnung, GewO. This provision is the central norm in German law, on the basis of which entrepreneurial activities can be prohibited. In the introduction, the author provides an overview of different forms of control and discusses the role of the courts in general, but also in the context of reviewing the control measures taken by the state. The author agrees that jurisprudence (case law is not a source of law in the countries of the European-Continental legal system. However, this should not lead to the wrong conclusion that the courts are neither qualified nor obliged to develop the law. After the introductory remarks, the author discusses the provisions contained in § 35 of the German Trade, Commerce and Industry Regulation Act (Gewerbeordnung. This example is of particular interest as it demonstrates various general principles of state control over private activities. While the provision originally contained a casuistic enumeration of individual cases, it nowadays uses a blanket clause. Accordingly, the concept of Unzuverlässigkeit ('unreliability ', which is not defined in more detail is the definitional element for a disqualification from the practice of commercial activities. Hence, the courts' task in dealing with the respective cases has significantly changed, as the control process involves consideration of both public and private interests, as well as striking a fair balance between the opposing public and private interests. The author points out that this is also justified as the legislator can hardly foresee all cases to which the provision might appear in practice. In particular, the author points out that the German legislator, unlike the legislators in some transformation states, has opted for having as few

  15. Generalized Archimedes' principle in active fluids

    Science.gov (United States)

    Razin, Nitzan; Voituriez, Raphael; Elgeti, Jens; Gov, Nir S.

    2017-09-01

    We show how a gradient in the motility properties of noninteracting pointlike active particles can cause a pressure gradient that pushes a large inert object. We calculate the force on an object inside a system of active particles with position-dependent motion parameters, in one and two dimensions, and show that a modified Archimedes' principle is satisfied. We characterize the system, both in terms of the model parameters and in terms of experimentally measurable quantities: the spatial profiles of the density, velocity and pressure. This theoretical analysis is motivated by recent experiments, which showed that the nucleus of a mouse oocyte (immature egg cell) moves from the cortex to the center due to a gradient of activity of vesicles propelled by molecular motors; it more generally applies to artificial systems of controlled localized activity.

    Highlights: • Parameter of Derivate air Contamination (DAC) allows to associate the type of air ventilation. • The construction and operation of IFMIF will be subjected to the regulations of the country in which it will be sited. • Structures, systems and components are assigned a particular safety important components (SIC, 1–2 and Non-SIC) clarification that is based on the consequences of their failure. • Reliability, Availability, Maintainability and Inspectability (RAMI) analysis has given a great contribution of the facility to optimize the configuration, particularly for the HVAC system. - Abstract: In 2013, the IFMIF, the International Fusion Material Irradiation Facility, presently in its Engineering Validation and Engineering Design Activities (EVEDA) phase, framed by the Broader Approach Agreement between Japan and EURATOM, accomplished in 2013 its mandate to provide the engineering design of the plant on schedule [1]. The IFMIF aims to qualify and characterize materials that are capable of withstanding the intense neutron flux originated in D-T reactions of future fusion reactors due to a neutron flux with a broad peak at 14 MeV, which is able to provide >20 dpa/fpy on small specimens in this EVEDA phase. The successful operation of such a challenging plant demands a careful assessment of the Conventional Facilities (CF), which have adequate redundancies to allow for the target plant availability [2]. The present paper addresses the design proposed in the IFMIF Intermediate Engineering Design Report regarding the CF, particularly the IFMIF's Nuclear and Industrial HVAC design. A preliminary feasibility study, including the initial configuration, calculations and reliability/availability analysis, were performed. The nuclear HVAC design was developed progressively; first, by establishing a conceptual design, starting from the system functional description, followed by the identification of the corresponding interfacing systems and their

    Nuclear techniques and methods were, are, and will be very important for many fields of science, agriculture, industry, etc. Among other examples one can remember role of the nuclear medicine (radiotherapy and radiodiagnostic methods) or semiconductors (communication, computing, information, etc.) which industrial production has been on initial stage based on activation analysis. One of very illustrative examples is application of nuclear methods in gold industry. This is given by favorable nuclear properties of gold. Uzbekistan is one of the main producers of gold. Open-cast mining and hydro metallurgic extraction (using leaching by cyanide and sorption by ion-exchange resin) is the mostly used technology. The typical gold ores are sulfide and contain elevated concentration of As and Sb. That needs special technology of gold extraction. Importance of gold for Uzbekistan economy is a reason why for many years there are carried out studies concerning to gold production. These studies include also nuclear methods and their results are successfully used in gold industry. The present paper gives a brief overview for period of 25 years. For many reasons most of these studies were not published before completely. Despite some results are obtained decades ago we decided to present the overview as an example how nuclear methods can cover requirements of the whole process. We are trying to sort these studies according to methods and applications

  4. Principles of Security Vulnerability Analysis of stationary industrial installations

    International Nuclear Information System (INIS)

    Borysiewicz, M.

    2006-01-01

    Security and safety have been key priorities at facilities that manufacture, store, use, or handle hazardous chemicals, after the terrorist attacks on the United States of September 11, 2001. Security improvements may be needed, especially at sites that pose a more attractive target to terrorists due to their economic importance, perceived level of consequences, and other factors. The first step in the process of managing security risks is to identify and analyze the threats and the vulnerabilities facing a facility by conducting a Security Vulnerability Analysis (SVA). The SVA is a systematic process that evaluates the likelihood that a threat against a facility will be successful. It considers the potential severity of consequences to the facility itself, to the surrounding community and on the energy supply chain. The objective of conducting a SVA is to identify security hazards, threats, and vulnerabilities facing a facility, and to evaluate the countermeasures to provide for the protection of the public, workers, national interests, the environment, and the company. With this information security risks can be assessed and strategies can be formed to reduce vulnerabilities as required. SVA is a tool to assist management in making decisions on the need for countermeasures to address the threats and vulnerabilities. The paper provides an overview of fundamental steps of SVA for stationary industrial installations. (author)

    2017-04-01

    Full Text Available The article is aimed at highlighting the strategic principles of formation and development of the biofuel production in Ukraine at a competitive level. The carried out comprehensive analysis of scientific publications indicates the relevance of the pace of development in the biofuel industry as in the world, so in Ukraine. However, the low level of consumption and production of biofuels in our country requires further research of strategic nature. It has been found that formation of the competitive production of biofuels in Ukraine would ensure the positive developments in the economic, energy, agro-industrial, and environmental directions. On the basis of the carried out SWOT-analysis, the author has evaluated internal forces and the system of internal shortages, as well as the resource potential of the agro-industrial complex towards the implementation of existing external opportunities and confronting various threats, emerging in the market conditions during the process of development and rise of the biofuel industry.

  16. Nutravigilance: principles and practices to enhance adverse event reporting in the dietary supplement and natural products industry.

    Science.gov (United States)

    Schmitz, Stephen M; Lopez, Hector L; MacKay, Douglas

    2014-03-01

    Nutravigilance is defined as "the science and activities relating to the detection, assessment, understanding and prevention of adverse effects related to the use of a food, dietary supplement, or medical food". The nutravigilance approach is derived from well-defined principles of pharmacovigilance in the drug and biologics industries, which have been developed and refined over a number of years through expert recommendations. While the primary purpose of nutravigilance is to protect customer/patient safety, it also serves to reduce product liability risks for manufacturers and marketing agents of such products. Compliance with the current FDA adverse event reporting requirements is suboptimal, and FDA oversight and enforcement activities have recently increased. In order to better protect customer and product safety, dietary supplement manufacturers must significantly change their current approach, and demonstrate a proactive, systematic, risk-based, scientific approach to product safety, similar to one utilized successfully in the pharmaceutical industry. While this article focuses on FDA regulations, the principles are widely relevant to the supplement industry in the rest of the world.

  17. Industry as a metabolic activity.

    Science.gov (United States)

    Smart, B

    1992-02-01

    The concept of "industrial economic metabolism" can provide a bridge to better understanding between environmentalists and industry. In nature each individual or species reacts to natural stimuli, competing with others for resources, extending its domain until it loses comparative advantage and comes to equilibrium with an adjacent competitor. Those species that succeed over time flourish; those that do not, diminish or disappear. Nature's rule book has no moral or ethical ingredient beyond self-interest. Corporate metabolisms are remarkably similar to those of nature. They too react to stimuli, collect and use resources, and grow or perish based on how effectively they compete. Corporate management recognizes and responds naturally and efficiently to cost and price signals. Through them it selects resources and converts them into useful products. The efficiency with which this is done is measured by profit, the lifeblood of the corporation and its means of growth. Profit thus provides a discipline on corporate behavior, encouraging efficient performers, and, by its absence, weeding out others. Unfettered by influences other than economics, the path to corporate success is unlikely to be a compassionate one. The dilemma of the manager is that to do what is socially "right" often conflicts with what must be done to survive and prosper. Fortunately, corporations' behavior can be altered by society when their purely economic role comes into conflict with other human values. The environment and the economy are not separate systems but intertwined to form a complex natural and social setting. The human-designed economic system depends on natural resource inputs, and in turn its metabolic wastes can overload the ecological system, threatening the long-term survivability of both. Increasing concern for the environment now gives the farsighted manager new latitude. There are competitive benefits in some pollution prevention. But there are not sufficiently strong forces to

It is based on Mixed Integer Linear Programming (MILP) and developed at Linkoeping University in Sweden. Several industries, ranging from the food industry to the pulp and paper industry, have hitherto been modelled and analyzed using the MIND method. In this paper the principles regarding the use of the method and the creation of constraints of the modelled system are presented. Two case studies are also included, a dairy and a pulp and paper mill, that focus some measures that can be evaluated using the MIND method, e.g. load shaping, fuel conversion and introduction of energy efficiency measures. The case studies illustrate the use of the method and its strengths and weaknesses. The results from the case studies are related to the main issues stated by the European Commission, such as reduction of greenhouse gas emissions, improvements regarding security of supply and increased use of renewable energy, and show great potential as regards both cost reductions and possible load shifting.

    2011-03-01

    Full Text Available This paper deals with basic principles of self-regulation of tourist complexes as regional socio-economic systems on the example of Sverdlovsk region. These include the principles of goal setting and the necessary diversity of economic entropy: in this case, these are important for the tourism industry and the human and natural resource and ecological potential. Is it shown how a tourist complex influences the socio-economic development of regional economic systems. In particular, tourism influences some of migration processes. Tourism development strategy in the Russian Federation at the tourist center level is analyzed. The need to develop such a strategy is due to the transition to market relations and, as a consequence, complexity of governmental regulation. It is substantiated that Sverdlovsk region is a subject to following strategy and might be successful in various sectors of tourism: business and congress and exhibition, urban entertainment, family and shopping tourism, sports, medical and recreational tourism.

    The oil, gas, and petrochemical industries face a dilemma, to be financially competitive while complying with strict and expanding environmental, safety, and health regulation. Companies need new tools and techniques, indeed a completely new paradigm for organizing and performing work. They must build efficient and flexible business processes, ones that rely on advanced information systems for improved decision making and productivity. And they must adopt a culture of change and improvement to permit the business to change as the business climate changes. Fortunately, two industry developments are changing the traditional business paradigm in a dramatic way; business reengineering and object technology. Applying principles of object technology in the performance of business reengineering makes available a new form of business modeling that transforms the technique of modeling a business while directly supported the development of its enabling information systems. This modeling technique is called Object Modeling and is becoming an important force in improving business competitiveness

  2. Principles and applications of knowledge management in the BC industry (with examples

    Full Text Available Many definitions define Knowledge Management as capturing, organizing and storing knowledge by different methods from various sources and transforming it into enduring value. The knowledge management is one of the most important principles that companies must explore and use to gain the competitive advantage, even in buildings and construction industry. There are various projects of knowledge management for the BC industry. One such project is e-COGNOS. Its key issues are knowledge management in the construction domain and documents interdependencies and consistency across projects and between enterprises. At the Urban Planning Institute of the Republic of Slovenia we are using very crude methods of knowledge management or we even can not call it a knowledge management. It is more or less information services or document management. With new technologies like Microsoft SharePoint services, we are hoping that we will be able to advance these old methods and use accumulated knowledge in a more sophisticated way.

    2015-04-01

    Full Text Available Nowadays, industrial robots are being pervasively used in almost every manufacturing organization for improving operational quality, safety and productivity. Depending on the nature of task to be performed, many varieties of robots are now commercially available from different manufacturers. For efficiently carrying out the designed task, a number of functional attributes of an industrial robot are also simultaneously responsible. Therefore, selection of an appropriate and competitive robot alternative becomes a complicated and equally challenging task for the decision makers. A quite strong model of multi-criteria decision-making is needed to deal with this problem of industrial robot evaluation and selection. In this paper, the applicability of fuzzy axiomatic design (FAD principles is explored for solving a real time robot selection problem. Seven candidate robots which are commercially available for light assembly operations are evaluated with respect to a mix of nine criteria. All these criteria are either qualitative in nature or expressed as a range of numerical values. Suitability rankings of all the feasible alternatives are derived using FAD methodology, thus establishing it as a systematic and dependable tool for solving industrial robot selection problems in fuzzy environment.

  5. Principles, effects and problems of differential power pricing policy for energy intensive industries in China

    Lin, Boqiang; Liu, Jianghua

    2011-01-01

    The Chinese government canceled the preferential power pricing policies for energy intensive industries and imposed a reverse differential pricing policy in order to promote energy efficiency and the adjustment and upgrading of the industrial structure. This article analyzes the principles of China's differential power pricing policy, the externalities of energy and the modified Ramsey pricing rule, and also points out the policy implications of China's differential power pricing policy. In our samples, we investigate eight power intensive products in the Henan province with respect to their power consumption per unit (power intensity), electricity cost, total cost, the electricity tariff and profit, in order to test the effects of the differential power pricing policy. The results show that the primary effect of the differential power pricing policy is that enterprises decrease their total costs and improve their productive efficiencies in advance, in anticipating a higher electricity tariff. -- Research highlights: → The article suggests a modified Ramsey pricing model where demand elasticity is replaced by elasticity of energy consumption and polluting elasticity to internalize the negative externality of high energy intensive industry. → The article assesses the effects of differential pricing policy through on-site survey of high energy intensive industries in Henan province and analyzes the reasons behind those effects. → The article presents the lessons and policy implications of implementing differential pricing policy aimed at energy conservation and emission reduction.

    On September 30, 1999, a criticality accident occurred at the uranium processing facility of the JCO Co. Ltd. (hereinafter referred to as ''JCO'') Tokai plant, located in Tokaimura, Ibaraki Prefecture. This was an unprecedented accident in Japan's history of peaceful use of nuclear power, resulting in three workers exposed to severe radiation, two of whom died, and the evacuation and enforced indoor confinement of local residents. Nuclear power suppliers must take personal responsibility for ensuring safety. In this connection, the electric power industry, heavy electric machinery manufacturers, fuel fabricators, and nuclear power research organizations gathered together to establish the Nuclear Safety Network (NSnet) in December 1999, based on the resolve to share and improve the level of the safety culture across the entire nuclear power industry and to assure that such an accident never occurs again. NSnet serves as a link between nuclear power enterprises, research organizations, and other bodies, based on the principles of equality and reciprocity. A variety of activities are pursued, such as diffusing a safety culture, implementing mutual evaluation among members, and exchanging safety-related information. Aiming to share and improve the safety culture throughout the entire nuclear power industry, NSnet thoroughly implements the principle of safety first, while at the same time making efforts to restore trust in nuclear power

    Plant natural products (PNPs) are widely used as pharmaceuticals, nutraceuticals, seasonings, pigments, etc., with a huge commercial value on the global market. However, most of these PNPs are still being extracted from plants. A resource-conserving and environment-friendly synthesis route for PNPs that utilizes microbial cell factories has attracted increasing attention since the 1940s. However, at the present only a handful of PNPs are being produced by microbial cell factories at an industrial scale, and there are still many challenges in their large-scale application. One of the challenges is that most biosynthetic pathways of PNPs are still unknown, which largely limits the number of candidate PNPs for heterologous microbial production. Another challenge is that the metabolic fluxes toward the target products in microbial hosts are often hindered by poor precursor supply, low catalytic activity of enzymes and obstructed product transport. Consequently, despite intensive studies on the metabolic engineering of microbial hosts, the fermentation costs of most heterologously produced PNPs are still too high for industrial-scale production. In this paper, we review several aspects of PNP production in microbial cell factories, including important design principles and recent progress in pathway mining and metabolic engineering. In addition, implemented cases of industrial-scale production of PNPs in microbial cell factories are also highlighted.

    Neutron activation analysis has been widely used in the industry and over the years played a key role in the development of manufacturing process as well as monitoring of the process flow. In this context NAA has been utilized both in R and D, and in the factory as a flexible analytical tool. It has been used successfully in numerous industries including broad categories such as Chemical, Pharmaceutical, Mining, Photographic, Oil and Gas, Automobile, Defense, Semiconductor and Electronic industries. Dow Chemical owns and operates a research reactor for analytical measurements of samples generated in both R and D, and manufacturing area in its plant in Midland, Michigan. Although most industries do not have reactors on their campus but use an off site reactor regularly, and often have in-house neutron sources such as a 252 Cf used primarily for NAA. In most industrial materials analysis laboratory NAA is part of a number of analytical techniques such as ICP-MS, AA, SIMS, FTIR, XRF, TXRF etc. Analysis of complex industrial samples may require data from each of these methods to provide a clear picture of the materials issues involved. With the improvement of classical analytical techniques, and the introduction of new techniques, e.g. TXRF, the role of NAA continues to be a key bench mark technique that provides accurate and reliable data. The strength of the NAA in bulk analysis is balanced by its weakness in providing surface sensitive or spatially resolved analysis as is required by many applications. (author)

    2006-03-15

    This policy paper demonstrated how restoring balance and clarity to Canada's regulatory environment will ensure the continued strength of the economy, environment, and communities. It was noted that regulatory outcomes that reflect the broad public interest can be achieved if 4 basic principles for economic regulation are pursued. These principles include strength, balance, efficiency, and clarity. In particular, this paper addressed the challenge facing Canada's natural gas delivery industry in terms of increased energy demand, tight supply, ageing infrastructure and increasing cost pressures on the energy system. It emphasized that transparent, efficient energy policy developed through informed debate can provide the foundation for a reliable, environmentally acceptable and sustainable energy future. It was suggested that immediate attention be given to rebalancing the regulatory processes that have placed short term considerations above the longer term strength of the natural gas system; improving the support for new natural gas supply development; reconsidering pricing in some energy markets where information has been distorted; and revisiting the regulatory processes that have become inefficient.

  15. The Working Principle and Use of High Pressures in the Food Industry

    Directory of Open Access Journals (Sweden)

    Karlović, S.

    2010-11-01

    Full Text Available High pressure in the food industry, as a new non-thermal method, is applied in many phases of food processing. This new non-thermal technology was developed in the 1990s. The main advantages of high-pressure processing are in the short time of processing which is between a few seconds and 30 minutes. Processing of solid or liquid food products with or without packaginghappens in the temperature interval 5 – 90 °C, and pressures 50 – 1000 MPa. The driving pressure is distributed uniformly through the whole product independently of its quantity and shape. These processing characteristics combined with improved food microbiological safety, less energy expenditure, low concentration of waste products and longer shelf life make high-pressure processing a very promising novel food technology. Combined with lower cost of treatment (but unfortunately higher initial cost of equipment compared to traditional processing technologies, it is also economically profitable. The main purpose of such treated food products are in preservation of sensory, nutritive and textural properties. As the temperature increase is very low, there are no significant changes in sensory properties, in contrast to conventional thermal processing (sterilization, pasteurization. However, with the combination of heating or cooling and high pressure, modification of existing and creation of new food products is possible. Today, high pressure is used for the treatment of meat products (inactivation of microorganisms, freezing and defrosting of foodstuffs, production of fruit juices (pasteurization, processing of oysters, modificationof milk characteristics (foaming etc. The main purpose of this work is to present the working principle and application of high pressure in the food industry.

    Risk assessment (RA) represents the first step to ensure the protection of the workers' health in all work sectors, production and services included. For this reason RA has become a legal duty for the occupational physician in his/her professional activity. The basic concepts of RA have been developed as a formal procedure for the management of chemical risks but they are currently applied to protect human health against all types of occupational and environmental risk factors. In the construction industry, in particular, chemical risk assessment is specially difficult due to the complexity of the working condition, and the variability and multiplicity of exposure. The critical aspects of RA in the construction industry will be discussed here, in the attempt to highlight how the occupational physician, making use of traditional and new tools, including biological monitoring, can address and partly overcome them.

    Ever stronger environmental concerns prompt the research in the area of heterogeneous catalysis to play an ever more crucial role to produce ever cleaner fuel from the refining of petroleum effluents. The catalytic active phase is often used in a dispersed state over a porous oxide material. This paper is a review of recent progress brought by periodic density functional theory (DFT) calculations in the area of two relevant industrial supported catalysts. We focus on two important supports used in the refining industry: anatase-TiO2 and γ-alumina. According to the various reaction conditions, the presence of H2O, H2 and H2S may change the surface states of the support. In particular, it is crucial to know and control the hydroxylation state depending on temperature and partial pressure of reactants (H2O, H2, H2S). The support effects on the catalytic active phases are presented for MoS2 particles, used in hydrodesulfurization catalysis, and for Pd particles, used in hydrogenation catalysis. It is shown how the wetting property and equilibrium morphology of the active phase depend on the support. A discussion on the impact for catalytic activities is provided.

    Staff in settings that care for children struggle to implement standards designed to promote moderate-to-vigorous physical activity (MVPA), suggesting a need for effective strategies to maximize the amount of time children spend in MVPA during scheduled PA opportunities. The purpose of this study was to compare the MVPA children accumulate during commonly played games delivered in their traditional format versus games modified according to the LET US Play principles. Children (K-5th) participated in 1-hour PA sessions delivered on non-consecutive days (summer 2014). Using a randomized, counterbalanced design, one of the six games was played for 20min using either traditional rules or LET US Play followed by the other strategy with a 10min break in between. Physical activity was measured via accelerometry. Repeated-measures, mixed-effects regression models were used to estimate differences in percent of time spent sedentary and in MVPA. A total of 267 children (age 7.5years, 43% female, 29% African American) participated in 50, 1-hour activity sessions. Games incorporating LET US Play elicited more MVPA from both boys and girls compared to the same games with traditional rules. For boys and girls, the largest MVPA difference occurred during tag games (+20.3%). The largest reduction in the percent of time sedentary occurred during tag games (boys -27.7%, girls -32.4%). Overall, the percentage of children meeting 50% time in MVPA increased in four games (+18.7% to +53.1%). LET US Play led to greater accumulation of MVPA for boys and girls, and can increase the percent of children attaining the 50% of time in MVPA standard. Copyright © 2015 Elsevier Inc.

    Arnold, Denis G; Oakley, James L

    2013-06-01

    As the pharmaceutical industry lobbies European regulators to permit direct-to-consumer advertising (DTCA) of prescription drugs in the European Union, we found that five leading companies violated industry-developed and -promulgated standards for ethical advertising in the United States. Utilizing multiple data sources and methods, we demonstrate a consistent failure by companies that market erectile dysfunction drugs to comply with the industry's guiding principles for ethical DTCA over a four-year period despite pledges of compliance by company leaders. Noncompliance resulted in children being exposed to sexually themed promotional messages more than 100 billion times. We argue that the guidelines are a coordinated effort by the industry to prevent unwanted federal regulation, and we introduce the concept of a blocking strategy to explain company behavior and to advance theoretical understanding of firms' public affairs strategies. We recommend policy responses to prevent deceptive practices, protect children from adult content, and promote genuine health care education.

    Plants continue to be a major source of medicines, as they have been throughout human history. In the present days, drug discovery from plants involves a multidisciplinary approach combining ethnobotanical, phytochemical and biological techniques to provide us new chemical compounds (lead molecules) for the development of drugs against various pharmacological targets, including cancer, diabetes and its secondary complications. In view of this need in current drug discovery from medicinal plants, here we describe another web database containing the information of pharmacophore analysis of active principles possessing antidiabetic, antimicrobial, anticancerous and antioxidant properties from medicinal plants. The database provides the botanical, taxonomic classification, biochemical as well as pharmacological properties of medicinal plants. Data on antidiabetic, antimicrobial, anti oxidative, anti tumor and anti inflammatory compounds, and their physicochemical properties, SMILES Notation, Lipinski's properties are included in our database. One of the proposed features in the database is the predicted ADMET values and the interaction of bioactive compounds to the target protein. The database alphabetically lists the compound name and also provides tabs separating for anti microbial, antitumor, antidiabetic, and antioxidative compounds. http://www.hccbif.info /

    Jilkova, Veronika; Frouz, Jan

    2016-04-01

    Toxic industrial deposits are often contaminated by heavy metals and the substrates have low pH values. In such systems, soil development is thus slowed down by high toxicity and acidic conditions which are unfavourable to soil fauna. Ants (Hymenoptera, Formicidae) are considered tolerant to heavy metal pollution and are known to increase organic matter content and microbial activity in their nests. Here, we focused on soil remediation caused by three ant species (Formica sanguinea, Lasius niger, and Tetramorium sp.) in an ore-washery sedimentation basin near Chvaletice (Czech Republic). Soil samples were taken from the centre of ant nests and from the nest surroundings (>3 m from nests). Samples were then analyzed for microbial activity and biomass and contents of organic matter and nutrients. As a result, ant species that most influenced soil properties was F. sanguinea as there were higher microbial activity and total nitrogen and ammonia contents in ant nests than in the surrounding soil. We expected such a result because F. sanguinea builds conspicuous large nests and is a carnivorous species that brings substantial amounts of nitrogen in insect prey to their nests. Effects of the other two ant species might be lower because of smaller nests and different feeding habits as they rely mainly on honeydew from aphids or on plant seeds that do not contain much nutrients.

  7. Applying Adaptive Agricultural Management & Industrial Ecology Principles to Produce Lower- Carbon Ethanol from California Energy Beets

    Science.gov (United States)

    Alexiades, Anthy Maria

    The life cycle assessment of a proposed beet-to-ethanol pathway demonstrates how agricultural management and industrial ecology principles can be applied to reduce greenhouse gas emissions, minimize agrochemical inputs and waste, provide ecosystem services and yield a lower-carbon fuel from a highly land-use efficient, first-generation feedstock cultivated in California. Beets grown in California have unique potential as a biofuel feedstock. A mature agricultural product with well-developed supply chains, beet-sugar production in California has contracted over recent decades, leaving idle production capacity and forcing growers to seek other crops for use in rotation or find a new market for beets. California's Low Carbon Fuel Standard (LCFS) faces risk of steeply-rising compliance costs, as greenhouse gas reduction targets in the transportation sector were established assuming commercial volumes of lower-carbon fuels from second-generation feedstocks -- such as residues, waste, algae and cellulosic crops -- would be available by 2020. The expected shortfall of cellulosic ethanol has created an immediate need to develop lower-carbon fuels from readily available feedstocks using conventional conversion technologies. The life cycle carbon intensity of this ethanol pathway is less than 28 gCO2e/MJEthanol: a 72% reduction compared to gasoline and 19% lower than the most efficient corn ethanol pathway (34 gCO2e/MJ not including indirect land use change) approved under LCFS. The system relies primarily on waste-to-energy resources; nearly 18 gCO2e/MJ are avoided by using renewable heat and power generated from anaerobic digestion of fermentation stillage and gasification of orchard residues to meet 88% of the facility's steam demand. Co-products displace 2 gCO2e/MJ. Beet cultivation is the largest source of emissions, contributing 15 gCO 2e/MJ. The goal of the study is to explore opportunities to minimize carbon intensity of beet-ethanol and investigate the potential

    2016-03-01

    Full Text Available The basic premise of sustainable development is that companies should completely re-evaluate their enterprise work logic and process organization. Most of the necessary changes concern employee stimulation and motivation. If we are truly interested in improving business results and the effectiveness of business processes – there would be no progress otherwise – we have to strive to break down the barriers between company management (leadership and employees in order to establish effective relationships between firms and customers. This paper presents research results of process manager activities in modern industrial enterprises, connected with a methodology proposal for the systematically-oriented process manager motivation of employees in accordance with the increased competitiveness of production and administration processes. It also presents an effective methodology of how to increase the positive effects of welldefined employee motivations from the process manager´s perspective. The core benefit of this methodology lies in the design of a systematic approach to the motivation process from the process manager side, allowing for radical performance improvement via production and administrative processes and the increased competitiveness of enterprise processes.

    The food contamination issue requires continuous control of food at each step of the production process. High quality and safety of products are equally important factors in the food industry. They may be achieved with several, more or less technologically advanced methodologies. In this work, we review the role, contribution, importance, and impact of ozone as a decontaminating agent used to control and eliminate the presence of microorganisms in food products as well as to extend their shelf-life and remove undesirable odors. Several researchers have been focusing on the ozone's properties and applications, proving that ozone treatment technology can be applied to all types of foods, from fruits, vegetables, spices, meat, and seafood products to beverages. A compilation of those works, presented in this review, can be a useful tool for establishing appropriate ozone treatment conditions, and factors affecting the improved quality and safety of food products. A critical evaluation of the advantages and disadvantages of ozone in the context of its application in the food industry is presented as well.

    The requirements for drying and thermobonding equipment working on the basis of the hot air flow-through system vary considerably due to the large variety of nonwovens qualities, production methods and required production speeds. It is therefore necessary to construct diverse drying systems in order to be able to offer appropriate machines for the desired purposes. Optimum heat and mass transfer from the penetrating air to the permeable material to be dried is ensured by through-air drying. Following Hans Fleissner`s invention of the through-air system for drying of textiles and its practical application in the perforated drum dryer for more than 50 years a second engineering breakthrough for the paper and nonwovens industry has been achieved by Gerold Fleissner with the high-tech through-air drum. This paper presents various possibilities of air flow through the material and provide criteria to facilitate selection of the proper drying system.

    Full Text Available Pesticides are used throughout the world as mixtures called formulations. They contain adjuvants, which are often kept confidential and are called inerts by the manufacturing companies, plus a declared active principle, which is usually tested alone. We tested the toxicity of 9 pesticides, comparing active principles and their formulations, on three human cell lines (HepG2, HEK293, and JEG3. Glyphosate, isoproturon, fluroxypyr, pirimicarb, imidacloprid, acetamiprid, tebuconazole, epoxiconazole, and prochloraz constitute, respectively, the active principles of 3 major herbicides, 3 insecticides, and 3 fungicides. We measured mitochondrial activities, membrane degradations, and caspases 3/7 activities. Fungicides were the most toxic from concentrations 300–600 times lower than agricultural dilutions, followed by herbicides and then insecticides, with very similar profiles in all cell types. Despite its relatively benign reputation, Roundup was among the most toxic herbicides and insecticides tested. Most importantly, 8 formulations out of 9 were up to one thousand times more toxic than their active principles. Our results challenge the relevance of the acceptable daily intake for pesticides because this norm is calculated from the toxicity of the active principle alone. Chronic tests on pesticides may not reflect relevant environmental exposures if only one ingredient of these mixtures is tested alone.

The basic education for engineers is carried out at universities and colleges. Graduate engineers who have been working in industrial establishments outside nuclear power stations for a longer time get their basic education in nuclear engineering through postgraduate studies. Graduate engineers with a basic knowledge of nuclear engineering are trained at the Nuclear Power Plant School of the nuclear power station Rheinsberg and at the nuclear power stations of the GDR under practical conditions relating to their future job. In addition to basic theoretical knowledge, training at a nuclear power plant simulator plays an important role. This permits the training of the staff under regular operating conditions including transient processes and under unusual conditions. Further particular modes of advanced professional training such as courses in radiation protection and further postgraduate studies are described. This system of education has proved successful. It will be developed further to meet the growing demands. (author)

    2015-05-01

    The paper deals with the creation of integrated monitoring systems. They combine fiber-optic classifiers and local sensor networks. These systems allow for the monitoring of complex industrial objects. Together with adjacent natural objects, they form the so-called geotechnical systems. An integrated monitoring system may include one or more spatially continuous fiber-optic classifiers based on optic fiber and one or more arrays of discrete measurement sensors, which are usually combined in sensor networks. Fiber-optic classifiers are already widely used for the control of hazardous extended objects (oil and gas pipelines, railways, high-rise buildings, etc.). To monitor local objects, discrete measurement sensors are generally used (temperature, pressure, inclinometers, strain gauges, accelerometers, sensors measuring the composition of impurities in the air, and many others). However, monitoring complex geotechnical systems require a simultaneous use of continuous spatially distributed sensors based on fiber-optic cable and connected local discrete sensors networks. In fact, we are talking about integration of the two monitoring methods. This combination provides an additional way to create intelligent monitoring systems. Modes of operation of intelligent systems can automatically adapt to changing environmental conditions. For this purpose, context data received from one sensor (e.g., optical channel) may be used to change modes of work of other sensors within the same monitoring system. This work also presents experimental results of the prototype of the integrated monitoring system.

    In vivo neutron activation has opened a new era of both clinical diagnosis and therapy evaluation, and investigation into and modelling of body composition. The techniques are new, but it is already clear that considerable strides can be made in increasing accuracy and precision, increasing the number of elements susceptible to measurement, enhancing uniformity, and reducing the dose required for the measurement. The work presently underway will yield significant data on a variety of environmental contaminants such as Cd. Compositional studies are determining the level of vital constituents such as nitrogen and potassium in both normal subjects and in patients with a variety of metabolic disorders. Therapeutic programs can be assessed while in progress. It seems likely that by the end of this century there will have been significant progress with this research tool, and exciting insights obtained into the nature and dynamics of human body composition

    2016-05-01

    Full Text Available We articulate and apply the generalized Onsager principle to derive transport equations for active liquid crystals in a fixed domain as well as in a free surface domain adjacent to a passive fluid matrix. The Onsager principle ensures fundamental variational structure of the models as well as dissipative properties of the passive component in the models, irrespective of the choice of scale (kinetic to continuum and of the physical potentials. Many popular models for passive and active liquid crystals in a fixed domain subject to consistent boundary conditions at solid walls, as well as active liquid crystals in a free surface domain with consistent transport equations along the free boundaries, can be systematically derived from the generalized Onsager principle. The dynamical boundary conditions are shown to reduce to the static boundary conditions for passive liquid crystals used previously.

    Since the beginning of the ITER Engineering Design Activities in 1992 the participation of industry in the European contribution to the ITER project has increased continuously. A major boost resulted from a framework contract between the European Commission acting through EFDA and the European industry grouping EFET EWIV regarding the industry contribution for the ITER engineering design. The members of EFET include Ansaldo (Italy), Belgatom (Belgium), Fortum (Finland), the AREVA companies Framatome ANP GmbH (Germany) and Framatome ANP SAS (France), IBERTEF (Spain) and NNC (United Kingdom). Together with other special European engineering companies and manufacturers EFET contributed significantly to ITER Engineering Design Activities. In 1996 a list of qualified competitive companies was established which could bid for the manufacturing of prototype components in initially 15, later 17 Technologies considered essential for ITER construction preparation. In total, contracts of about 70 Mio Euro have been awarded to industry during the period 1993 to 2004. In addition to engineering design and prototype manufacturing, industry participated in various assessments of the ITER project and ITER siting investigations. Furthermore, industry has been invited by the European Commission to introduce its proposals for the promotion of the ITER project in Europe and abroad and later for the organization and management of ITER construction.

    presence of the audit and monitoring that do not address the local conditions of the mining operations. Based on the above the following concepts were thought of to improve the environmental conditions in mining sector: 1. Was developed the Regional Environmental Management principle based on the local conditions such as physiographic region, local population, and socioeconomic conditions of the area; 2. Devised were criteria for the risk assessment for developing countries. Where the fundamental principals were public health, both near and far from the operation, environmental and biodiversity impact, waste management, long- and short- term rehabilitation plans, compliance with international standards and norms. 3. Developed was the mechanism of the economic motivation to make mining operations "environmentally friendly" that includes defrayal of expenses from both direct and indirect damages. 4. Identified were spheres of possible cooperation between mining companies, government organizations, and the NGOs. These include development of international standards for Good Neighbor Agreement, exchange of environmental information, exchange of successful environmental, health, and safety practices between mining operations from developed and developing countries. The study showed the dire necessity for the mining industry that operates in developing countries to adopt the successful environmental practices used in developed countries. To achieve this goal the Regional Environmental Management principle, the risk assessment criteria, the mechanism of the economic motivation and the principles for international cooperation can play an extremely important role.

    A range of decontaminated spices of industrial use have been examinated for their enzymes (catalase, peroxidase, amylase, lipase activity). The genuine enzymes remain fully active in irradiated spices, whereas the microbial load is clearly reduced. In contrast steam treated spices no longer demonstrate enzyme activities. Steam treatment offers e.g. black pepper without lipase activity, which can no longer cause fat deterioration. Low microbial load in combination with clearly detectable enzyme activity in spices is an indication for irradiation, whereas, reduced microbial contamination combined with enzyme inactivation indicate steam treatment of raw material [de

    African countries are a major potential market for the tobacco industry, and the smoking epidemic is at various stages of evolution across the continent. Ghana is an African country with a low prevalence of smoking despite an active tobacco industry presence for over 50 years. This study explores potential reasons for this apparent lack of industry success. To explore the history of tobacco industry activity in Ghana and to identify potential reasons for the current low prevalence of smoking. A search was made of tobacco industry archives and other local sources to obtain data relevant to marketing and consumption of tobacco in Ghana. British American Tobacco, and latterly the International Tobacco Company and its successor the Meridian Tobacco Company, have been manufacturing cigarettes in Ghana since 1954. After an initial sales boom in the two decades after independence in 1957, the sustained further increases in consumption typical of the tobacco epidemic in most countries did not occur. Possible key reasons include the taking of tobacco companies into state ownership and a lack of foreign exchange to fund tobacco leaf importation in the 1970s, both of which may have inhibited growth at a key stage of development, and the introduction of an advertising ban in 1982. BAT ceased manufacturing cigarettes in Ghana in 2006. The tobacco industry has been active in Ghana for over 50 years but with variable success. The combination of an early advertising ban and periods of unfavourable economic conditions, which may have restricted industry growth, are likely to have contributed to the sustained low levels of tobacco consumption in Ghana to date.

    Leishmaniasis is a complex disease with a broad spectrum of clinical presentations. We evaluated the anti-leishmanial effects of Nigella sativa L. (Ranunculaceae) against Leishmania tropica and Leishmania infantum with an in vitro model. Antileishmanial effects of essential oil and methanolic extract of N. sativa (0-200 µg/mL) and thymoquinone (0-25 µg/mL) on promastigotes of both species and their cytotoxicity activities against murine macrophages were evaluated using the MTT assay at 24, 48, and 72 h. Moreover, their leishmanicidal effects against amastigotes were investigated in a macrophage model, for 48 and 72 h. The findings showed that essential oil (L. tropica IC50 9.3 μg/mL and L. infantum IC50 11.7 μg/mL) and methanolic extract (L. tropica IC50 14.8 μg/mL and L. infantum IC50 15.7 μg/mL) of N. sativa, particularly thymoquinone (L. tropica IC50 1.16 μg/mL and L. infantum IC50 1.47 μg/mL), had potent antileishmanial activity on promastigotes of both species after 72 h. In addition, essential oil (L. tropica IC50 21.4 μg/mL and L. infantum IC50 26.3 μg/mL), methanolic extract (L. tropica IC50 30.8 μg/mL and L. infantum IC50 34.6 μg/mL), and thymoquinone (L. tropica IC50 2.1 μg/mL and L. infantum IC50 2.6 μg/mL) mediated a significant decrease in the growth rate of amastigote forms of both species. Thymoquinone (CC50 38.8 μg/mL) exhibited higher cytotoxic effects against murine macrophages than the other extracts. N. sativa, especially its active principle, thymoquinone, showed a potent leishmanicidal activity against L. tropica and L.infantum with an in vitro model.

    2016-09-01

    Full Text Available Purpose: Lean Manufacturing is widely regarded as a potential methodology to improve productivity and decrease costs in manufacturing organisations. The success of lean manufacturing demands consistent and conscious efforts from the organisation, and has to overcome several hindrances. Industry 4.0 makes a factory smart by applying advanced information and communication systems and future-oriented technologies. This paper analyses the incompletely perceived link between Industry 4.0 and lean manufacturing, and investigates whether Industry 4.0 is capable of implementing lean. Executing Industry 4.0 is a cost-intensive operation, and is met with reluctance from several manufacturers. This research also provides an important insight into manufacturers’ dilemma as to whether they can commit into Industry 4.0, considering the investment required and unperceived benefits. Design/methodology/approach: Lean manufacturing is first defined and different dimensions of lean are presented. Then Industry 4.0 is defined followed by representing its current status in Germany. The barriers for implementation of lean are analysed from the perspective of integration of resources. Literatures associated with Industry 4.0 are studied and suitable solution principles are identified to solve the abovementioned barriers of implementing lean. Findings: It is identified that researches and publications in the field of Industry 4.0 held answers to overcome the barriers of implementation of lean manufacturing. These potential solution principles prove the hypothesis that Industry 4.0 is indeed capable of implementing lean. It uncovers the fact that committing into Industry 4.0 makes a factory lean besides being smart. Originality/value: Individual researches have been done in various technologies allied with Industry 4.0, but the potential to execute lean manufacturing was not completely perceived. This paper bridges the gap between these two realms, and identifies

    Full Text Available This empirical paper explores trends in innovation activities measured by a countries’ total patent application submission intensity relative to its population, and by analyzing U.S. granted patents data for cohorts of developed countries and developing countries. In addition to tabular and graphical analyses, I use a baseline regression model and a variant model thereof to assess the relative influence of a set of aggregate variables on innovation activities in eight manufacturing industries across two cohorts of countries (developed and developing where each cohort contains eight individual countries. Eight industries included in this study are: Chemical, Petroleum, electrical and electronics equipment, machinery, pharmaceutical, plastic, computer, and textile. The cohort of developed countries includes Australia, Canada, Czech Republic, France, Italy, Poland, Switzerland, and the United States. The cohort of developing countries includes Brazil, China, India, Malaysia, Mexico, Russia, South Africa, and Turkey. Per regression results, ethnic diversity is a statistically significant positive determinant of innovation for all industry aggregate patent count for both high income and developing countries. Also, per capita electricity usage, R&D expenditure as percent of GDP, and percent of population with internet access are three positive factors of innovation irrespective of industrial subsectors and position of a country in the development echelon. Interestingly, impact of ICT-services export is statistically significant and innovation boosting in developing countries in the cohort relative to countries in the cohort of developed countries. It also appears that trade openness served as a stronger stimulant of innovation activities for developing countries’ but not as much for the cohort of developed or high-income countries. This paper attempts to extend the literature on cross-country comparison of innovation activities by using two

    1994-01-01

    The purpose of organization and management development activities in the commercial nuclear power industry is to foster high levels of power plant performance and safety through improved human performance. The NRC has been working to develop assessment tools to assay the effects of organizational factors on plant safety. The utility industry has been working on initiatives targeting individual accountability, the improvement of plant performance and the elimination of the items identified through the NRC assessment process. Organization and management activities do not focus on industry organizational charts, but on the personnel processes and dimensions (factors) that affect safety and economic performance. As individual terms these activities are often combined and referred to as organizational factors. As an area of study, organizational factors has become more prominent as the industry emphasis has switched in recent years from hardware issues related to safety and economics, to personnel-related issues. Beyond the obvious safety objectives affected by improved human performance, plant performance improvements, in areas such as capacity factors, can be achieved through improved human performance. For example, it is estimated that as many as half of the unplanned reactor scrams are caused by personnel errors. The integrated effect of these scram-initiating errors is conservatively estimated to be 100 lost capacity days per year. The financial impact of these events is estimated to be $100M per year

    A thin layer activation method was reviewed for non-destructive, rapid, precise and real-time measurement of wear and corrosion. The review included wear measurement, the principle of the method, actual measurement, application, and laws and regulations. The method is to activate the material surface alone by accelerated ions like p, d and He ions produced by cyclotron, Van de Graaf apparatus or other accelerators and to utilize the yielded radioisotopes as a tracer, is widely used in the tribology field, and is more useful than the previous method with the reactor since it activated the whole material. Application of the method was reportedly resulted in saving the 80% cost and 90% time in the wear measurement of automobile parts such as engine and transmission. Actually, the activated material was combined into the part to be run and the radioactivity was to be measured externally or in the worn particles suitably collected. The activation thickness was generally in the range of 10-200 μm and the resultant radioactivity, 0.2-2 MBq. In most cases in Japan, the method would be under the law concerning prevention from radiation hazards due to radioisotopes, etc. (K.H.)

    Full Text Available This work fits within the framework of sustainable management of sludge generated from wastewater treatment in industrial network. The studied sludge comes from an industry manufacturing sanitary ware products.Physico-chemical and mineralogical characterization was performed to give an identity card to the sludge. We noted the absence of metal pollution.The industrial sludge has been subjected to thermal activation at various temperatures (650°C to 850°C. The pozzolanic activity was evaluated by physico- chemical and mechanical methods [1]. Pozzolanicity measurement was carried out based on Chapelle test and conductivity revealed the existence of pozzolanic properties of the calcined samples. The best pozzolanic reactivity was obtained for the sample calcined at 800°C. We noticed a decrease in the reactivity of the sample calcined at 850°C. In addition, analysis by means of X-ray diffraction and Fourier transform infrared spectroscopy showed that sludge recrystallization begins at a temperature of 850°C. Pozzolanicity index of the thermally treated samples was determined by measuring the mechanical resistance of mortar specimens previously kept in a saturated lime solution for 28 days (ASTM C618 [2]. The best pozzolanic activity index was obtained for the sample calcined at 800°C (109.1%.This work is a contribution to the research for new supplying sources of raw materials and additives in the field of construction. It presents a proposition of a promising solution for the valorization of waste material as an additive instead of being discharged into open air dumps causing a major environmental problem.

  13. Active materials for adaptive architectural envelopes based on plant adaptation principles

    Directory of Open Access Journals (Sweden)

    Marlen Lopez

    2015-06-01

    Full Text Available In this paper, the authors present research into adaptive architectural envelopes that adapt to environmental changes using active materials, as a result of application of biomimetic principles from plants to architecture. Buildings use large amounts of energy in order to maintain their internal comfort, because conventional buildings are designed to provide a static design solution. Most of the current solutions for facades are not designed for optimum adaptation to contextual issues and needs, while biological solutions to adaptation are often complex, multi-functional and highly responsive. We focus on plant adaptations to the environment, as, due to their immobility, they have developed special means of protection against weather changing conditions. Furthermore, recent developments in new technologies are allowing the possibility to transfer these plant adaptation strategies to technical implementation. These technologies include: multi-material 3D printing, advances in materials science and new capabilities in simulation software. Unlike traditional mechanical activation used for dynamic systems in kinetic facades, adaptive architectural envelopes require no complex electronics, sensors, or actuators. The paper proposes a research of the relationship that can be developed between active materials and environmental issues in order to propose innovative and low-tech design strategies to achieve living envelopes according to plant adaptation principles.

    What are the human rights responsibilities of pharmaceutical companies with regard to access to medicines? The state-based international human rights framework has long struggled with the issue of the human rights obligations of non-state actors, a question sharpened by economic globalization and the concomitant growing power of private for-profit actors ("business"). In 2011, after a six-year development process, the UN Human Rights Council unanimously endorsed the Guiding Principles advanced by the UN Secretary General's Special Representative on Business and Human Rights, John Ruggie. The Ruggie Principles sought to clarify and differentiate the responsibilities of states and non-state actors-in this case, "business" -with respect to human rights. The framework centered on "three core principles: the state duty to protect against human rights abuses by third parties, including business; the corporate responsibility to respect human rights; and the need for more effective access to remedies." The "Protect, Respect, and Remedy" Framework emerged from a review of many industrial sectors operating from local to global scales, in many regions of the world, and involving multiple stakeholder consultations. However, their implications for the pharmaceutical industry regarding access to medicines remain unclear. This article analyzes the 2008 Human Rights Guidelines for Pharmaceutical Companies in relation to Access to Medicines advanced by then-UN Special Rapporteur on the Right to Health, Paul Hunt, in light of the Ruggie Principles. It concludes that some guidelines relate directly to the industry's responsibility to respect the right to access to medicines, and form a normative baseline to which firms should be held accountable. It also finds that responsibility for other guidelines may better be ascribed to states than to private actors, based on conceptual and practical considerations. While not discouraging the pharmaceutical industry from making additional

    Climate change is underway and even if mitigation measures are successfully implemented, societies will have to adapt to new climatic conditions in the near future and further. This session had been proposed to gather different studies dedicated to the climate change impact on some human activities, and discuss the possible ways of adaptation. Climate change is often presented in terms of global mean temperature evolutions, but what is important for adaptation concerns the local evolutions, and rather of the variability and extremes than of the mean of the involved meteorological parameters. In the session, studies and applications will be presented, covering different economical and industrial activities, such as energy production, (re-) insurance and risk assessment, water management or tourism.

    International Nuclear Information System (INIS)

    2005-01-01

    It has been ten years since AGRICE was founded to support technological research in the field of bio-products. Even if bio-products are indeed a commercial reality, and growing in diversity, they are still marginal in the marketplace. However, the amplification of the greenhouse effect, our increasing energy dependence, the inexorable rise in oil prices, international competition and the emergence of a genuine political awareness are all factors that converge in favour of bio-products, offering a promising future. Of course, the development of bio-products is dependent on a number of conditions: biomass resources, technological advances, mobilisation of actors through dynamic research programmes (conversion of lignocellulosic biomass for alternative fuels or hydrogen, bio-technology applied to chemicals), new agro-industrial supply chains, financial instruments to bridge the cost gap with fossil fuels, a national strategy supported by a public authority dedicated to non-food uses. In the immediate future, the recent decision to open up the biofuels market via implementation of the European biofuels directive (5.75% of the market in 2010) provides an opportunity to lay the groundwork for a veritable industry of plant-based products, opening the way to the bio-refineries of the future. There is considerable potential for the development of bio-products in France. An additional 25 to 30 million tonnes-oil-equivalent (toe) of agricultural and forestry biomass could be processed into energy and industrial bio-products in France. Accordingly we can set our sights on an overall objective of substituting plant feedstocks for petroleum used in fuels and chemicals, on the order of 10% in 2020, and 20 to 30% by 2030-2050. To achieve these goals many technological advances will be necessary, with constant attention to the requirements of sustainable development. In this respect AGRICE is an invaluable tool for guiding, catalysing and supporting research efforts in these fields

    Xiao, Jianping; Frauenheim, Thomas

    2012-09-20

    Using first-principle thermodynamics, we have studied surface phase diagrams of Cu substitutional ZnO(0001) surfaces under industrial conditions. On the one hand, the Cu substituted on Zn sites can promote efficient formation of oxygen vacancies on the ZnO(0001) surface. It can improve the activity on the Cu/ZnO(0001) surface. On the other hand, metallic monolayers containing certain Cu and Zn atoms can be also formed, accompanied by the oxygen vacancies formation. We have further investigated CO2 adsorption and reduction on these metallic monolayers. These metallic monolayers prefer to have an intermediate binding strength with the CO2 molecule. The intermediate binding strength was expected to be optimized for subsequent CO2 reduction. We have performed further studies and demonstrated successfully the improved catalysis for the subsequent CO2 reduction on these metallic monolayers. The relevant mechanism can be interpreted with the second synergy effect. The d-band states of these metallic monolayers, supported on the ZnO(0001) surface, are tuned to shift upward, that is, more close to Fermi level. Therefore, these metallic monolayers indeed exhibit promoted catalysis, in comparison with reported metallic surfaces in the literature.

    Full Text Available In this research the theoretical principles of psychological analysis of group project activity of students in the process of learning foreign language are defined on the basis of subject-activity, socio-psychological and cognitive paradigms. The approaches of different authors to the understanding of the concept of project and in particular group project activity are considered. The difficulties of the theoretical analysis of this specific notion are indicated due to the considerable variety of subjects, types and forms of the pedagogical activity, academic disciplines regarding which the researches are being carried out. Not disclosed aspects of organizing the group project activity of students are being determined, among them is a project group as an autonomous subject of joint activity for the realization students’ project activity while learning a foreign language; forming psychological readiness of teacher and student to use project method; the role of metacognitive aspect in the surrounding, where the project activity is being carried out; group functioning through the project work as a subject of group examination. It has been indicated that the analysis of project activity as an innovative technology must include its assessment as a condition of student’s developing as a subject of learning activity, his personal, socio-psychological, intellectual and professional self-perfection. Three levels of subjectivity in group project activity are being distinguished: teacher; each particular student; and student project group. Interaction between teacher and student is based on subject-subject relations. An organization of a project activity while learning a foreign language is considered as the one in which the student is moving in order to get the manager position and to master the basis of expert knowledge. Hereby, the main stress is on the group role as a subject of group examination, and also on metacognitive character of the

    Full Text Available Business subjects in any national economy perform activities results of which are products, services or goods directly distributed to the market network. Volume of products differs according to the level of operational facilities, number of producers and the level of their facilities. Based on the development of information technology, there arise new specialization fields and new ranges of goods. Classification criteria are developed to qualify level of production and for enlistment of a firm to a particular branch. Currently the criteria of production classification are being developed. The understanding of these principles is particularly important on the bachelor level of the specialization Trade Management, where students are getting acquainted with the characteristics of goods, creative and degradation influences on utility, etc. Students are encouraged to understand how the quality and criteria mentioned above influence market prices. Teaching emphasis is put on the complexity of food assortment and the knowledge of Czech and EU legalislation relating to hygienic aspects and health quality of production, processing, and selling of food products. This complex procedure enables to obtain an overall survey of the origin of particular products, their catering, and sales. This means that the students obtain an idea about the complexity of relations existing among the origin of products, their sales and their consumption.

  12. Teollisuuden Voima Oy - Industrial Power Company Ltd. Local information activity

    International Nuclear Information System (INIS)

    Engros, Taina

    1989-01-01

    There are two nuclear power producers in Finland - the state-owned power company Imatran Voima Oy which operates two 440 MW Soviet-made PWR units in southern Finland, east of Helsinki and the Teollisuuden Voima Oy - Industrial Power Company Ltd, or TVO, owned by Finnish industrial companies. TVO operates two 710 MW ABB ATOM BWR units producing about one fifth of the country's electricity consumption. Operating experiences are extremely good from all Finnish nuclear power plants. The Finns' attitude towards nuclear power has changed into a positive direction in recent times. This can probably be noted as an international trend now that the Chernobyl accident is becoming an incident of the past. The Finnish citizens and politicians are facing two questions; first, what is their attitude towards nuclear power as a source of energy, in other words, do they approve of the plants currently in operation. The second question is how they stand on the building of new plants. It is probably another universal phenomenon that the attitudes of people living in the vicinity of nuclear power plants are less critical than the attitudes of those living farther away. This does not, by any means, result in local information activity being easier or less important than nationwide information activity. On the contrary, local decision-makers, local media and inhabitants are those who can, and through whom we can, influence also wider circles. The Nuclear Energy Act, which became effective in Finland last year, defines that the final decision on whether nuclear power plants can be built inside a municipality, is made at local level. As far as TVO is concerned one factor making local information activity easier is the small size of the locality. The difficulty TVO has to face is the people's suspicion of information activity. All information is considered propaganda, regardless of its form, and only negative news are considered information. Also, a large proportion of people are passive

  13. Redistribution Principle Approach for Evaluation of Seismic Active Earth Pressure Behind Retaining Wall

    Maskar, A. D.; Madhekar, S. N.; Phatak, D. R.

    2017-11-01

    The knowledge of seismic active earth pressure behind the rigid retaining wall is very essential in the design of retaining wall in earthquake prone regions. Commonly used Mononobe-Okabe (MO) method considers pseudo-static approach. Recently there are many pseudo-dynamic methods used to evaluate the seismic earth pressure. However, available pseudo-static and pseudo-dynamic methods do not incorporate the effect of wall movement on the earth pressure distribution. Dubrova (Interaction between soils and structures, Rechnoi Transport, Moscow, 1963) was the first, who considered such effect and till date, it is used for cohesionless soil, without considering the effect of seismicity. In this paper, Dubrova's model based on redistribution principle, considering the seismic effect has been developed. It is further used to compute the distribution of seismic active earth pressure, in a more realistic manner, by considering the effect of wall movement on the earth pressure, as it is displacement based method. The effects of a wide range of parameters like soil friction angle (ϕ), wall friction angle (δ), horizontal and vertical seismic acceleration coefficients (kh and kv); on seismic active earth pressure (Kae) have been studied. Results are presented for comparison of pseudo-static and pseudo-dynamic methods, to highlight the realistic, non-linearity of seismic active earth pressure distribution. The current study results in the variation of Kae with kh in the same manner as that of MO method and Choudhury and Nimbalkar (Geotech Geol Eng 24(5):1103-1113, 2006) study. To increase in ϕ, there is a reduction in static as well as seismic earth pressure. Also, by keeping constant ϕ value, as kh increases from 0 to 0.3, earth pressure increases; whereas as δ increases, active earth pressure decreases. The seismic active earth pressure coefficient (Kae) obtained from the present study is approximately same as that obtained by previous researchers. Though seismic earth

    Bhattacharjee, Joydeep

    2015-05-07

    Nitrogen-doped graphene and carbon nanotubes are popularly in focus as metal-free electrocatalysts for oxygen reduction reactions (ORR) central to fuel cells. N-doped CNTs have been also reported to chemisorb mutually, promising a route to their robust predetermined assembly into devices and mechanical reinforcements. We propose from first principles a common mechanistic understanding of these two aspects pointing further to a generic chemical activation of carbon atoms due to substitution by nitrogen in experimentally observed configurations. Wannier-function based orbital resolved study of mechanisms suggests increase in C-N bond-orders in attempt to retain π-conjugation among carbon atoms, causing mechanical stress and loss of charge neutrality of nitrogen and carbon atoms, which remedially facilitate chemical activation of N-coordinated C atoms, enhancing sharply with increasing coordination to N and proximity to zigzag edges. Activated C atoms facilitate covalent adsorption of radicals in general, diradicals like O2 relevant to ORR, and also other similarly activated C atoms, leading to self-assembly of graphenic nanostructures while remaining inert to ordinary graphenic C atoms.

    The accident at Chernobyl' Atomic Power Plant has drawn attention to the ecological aspects of the development of the nuclear power industry. It has become clear that the stage of discussions of the importance of ecological problems and of the advisability of studying them further has passed. We now face the stage of carrying out specific tasks: the creation of regional and global monitoring systems; the collection and analysis of data on the effect of nuclear power on nature and humans; modeling and optimization of the strategy for developing the power industry with consideration for ecological aspects; ecological factoring in scientific and technical decisions related to atomic power plant design and siting; and so forth. Three main areas of application of ecological information science can be identified in the nuclear power industry: the creation of global data banks on the safety and reliability of enterprises involved in the nuclear fuel cycle; the development of standard tools for processing and analysis of ecological data; and the creation of tools to support decisions in the field of ecology. The authors' experience in working with information systems and various groups of untrained users (biologists, medical workers, ecologists, etc.) makes possible the conclusion that the most important requirement is a convenient interface that does not require a great deal of effort to master. In the systems discussed here, the authors used structured query languages and menus

Particularly, the application of INAA is well recognized for analysis of microquantitis of heavy metals as well as toxic elements in biological samples. In this work the possibility of the determination of MIBI, MAG-3 and sodium fitate elemental composition by INAA was investigated Analytical information about the concentration and/or detection limits of some toxic elements (Hg, Cd, As, Se, Sb) and other trace elements of interest (Fe, Cr, Co, Zn, Br) was obtained. The samples were irradiated in the CAb Ra-6 nuclear research reactor

    Background: Nigella sativa seed has been used in folk medicine against many ailments including infections. The present study was aimed to investigate activity of thymoquinone, in vitro, against clinical isolates of Mycobacterium tuberculosis. Methods: Mycobacteria obtained from patients of King Fahd Hospital of University, Alkhobar, Saudi Arabia were subcultured at 37 degree C in MGIT tubes containing Middle brook broth and OADC growth supplement and growth detected by BACTEC Micro MGIT fluoro meter on day 10. Mycobacteria were then inoculated in MGIT tubes containing thymoquinone 2.5, 5, 10, 20, 40, 80 micro g/ml, streptomycin 1.25 micro g/ml or controls in Middle brook broth plus supplement, incubated at 37 degree C for 14 days and read daily for fluorescence. In addition, isolates were inoculated in culture tubes containing Middle brook agar (plus supplement) in presence of thymoquinone 2.5, 5, 10, 20, 40, 80 micro g/ml, streptomycin 1.25 micro g/ml or controls, and incubated at 37 degree C for 4 weeks. Results: In Middle brook broth, fluorescence test for tuberculosis was negative with thymoquinone 20, 40 and 80 micro g/ml and streptomycin 1.25 micro g/ml up to day 14. With controls, thymoquinone 2.5, 5 and 10 micro g/ml fluorescence was detectable from day 10 to 14. In Middle brook agar, there was no visible growth of tubercle bacillus with thymoquinone 20, 40 and 80 micro g/ml and streptomycin 1.25 micro g/ml, however, with controls, thymoquinone 2.5 and 5 micro g/ml abundant and with 10 micro g/ml few colonies were observed. Conclusions: Thymoquinone possesses activity against M. tuberculosis with MIC of 20 micro g/ml and has potential for further investigation. Our study confirms the benefit of N. sativa in native medicine against chest infection. (author)

    This chapter addresses past, ongoing, and short (to 2010) and medium-term (to 2030) future actions that can be taken to mitigate GHG emissions from the manufacturing and process industries. Globally, and in most countries, CO{sub 2} accounts for more than 90% of CO{sub 2}-eq GHG emissions from the industrial sector (Price et al., 2006; US EPA, 2006b). These CO{sub 2} emissions arise from three sources: (1) the use of fossil fuels for energy, either directly by industry for heat and power generation or indirectly in the generation of purchased electricity and steam; (2) non-energy uses of fossil fuels in chemical processing and metal smelting; and (3) non-fossil fuel sources, for example cement and lime manufacture. Industrial processes also emit other GHGs, e.g.: (1) Nitrous oxide (N{sub 2}O) is emitted as a byproduct of adipic acid, nitric acid and caprolactam production; (2) HFC-23 is emitted as a byproduct of HCFC-22 production, a refrigerant, and also used in fluoroplastics manufacture; (3) Perfluorocarbons (PFCs) are emitted as byproducts of aluminium smelting and in semiconductor manufacture; (4) Sulphur hexafluoride (SF{sub 6}) is emitted in the manufacture, use and, decommissioning of gas insulated electrical switchgear, during the production of flat screen panels and semiconductors, from magnesium die casting and other industrial applications; (5) Methane (CH{sub 4}) is emitted as a byproduct of some chemical processes; and (6) CH{sub 4} and N{sub 2}O can be emitted by food industry waste streams. Many GHG emission mitigation options have been developed for the industrial sector. They fall into three categories: operating procedures, sector-wide technologies and process-specific technologies. A sampling of these options is discussed in Sections 7.2-7.4. The short- and medium-term potential for and cost of all classes of options are discussed in Section 7.5, barriers to the application of these options are addressed in Section 7.6 and the implication of

  5. Environmental Defense Fund Oil and Gas Methane Studies: Principles for Collaborating with Industry Partners while Maintaining Scientific Objectivity

    Science.gov (United States)

    Hamburg, S.

    2016-12-01

    Environmental Defense Fund (EDF) launched a series of 16 research studies in 2012 to quantify methane emissions from the U.S. oil and gas (O&G) supply chain. In addition to EDF's funding from philanthropic individuals and foundations and in-kind contributions from universities, over forty O&G companies contributed money to the studies. For a subset of studies that required partner companies to provide site access to measure their equipment, five common principles were followed to assure that research was objective and scientifically rigorous. First, academic scientists were selected as principal investigators (PIs) to lead the studies. In line with EDF's policy of not accepting money from corporate partners, O&G companies provided funding directly to academic PIs. Technical work groups and steering committees consisting of EDF and O&G partner staff advised the PIs in the planning and implementation of research, but PIs had the final authority in scientific decisions including publication content. Second, scientific advisory panels of independent experts advised the PIs in the study design, data analysis, and interpretation. Third, studies employed multiple methodologies when possible, including top-down and bottom-up measurements. This helped overcome the limitations of individual approaches to decrease the uncertainty of emission estimates and minimize concerns with data being "cherry-picked". Fourth, studies were published in peer-reviewed journals to undergo an additional round of independent review. Fifth, transparency of data was paramount. Study data were released after publication, although operator and site names of individual data points were anonymized to ensure transparency and allow independent analysis. Following these principles allowed an environmental organization, O&G companies, and academic scientists to collaborate in scientific research while minimizing conflicts of interest. This approach can serve as a model for a scientifically rigorous

    regard to output performance and standing regulation, the availability of tDCS, tACS, or tPCS to the public would not introduce risk, provided such devices are responsibly manufactured and legally marketed. In Part 3, we develop voluntary manufacturer guidance for limited output tES that is aligned with current regulatory standards. Based on established medical engineering and scientific principles, we outline a robust and transparent technical framework for ensuring limited output tES devices are designed to minimize risks, while also supporting access and innovation. Alongside applicable medical and government activities, this voluntary industry standard (LOTES-2017) further serves an important role in supporting informed decisions by the public.

    Recent studies have demonstrated that factors influencing perception, such as Gestalt grouping cues, can influence the storage of information in visual working memory (VWM). In some cases, stationary cues such as stimulus similarity lead to superior VWM performance. However, the neural correlates underlying these benefits to VWM performance remain unclear. One neural index, the contralateral delay activity (CDA) is an event-related potential that shows increased amplitude according to the number of items held in VWM and asymptotes at an individual’s VWM capacity limit. Here, we applied the CDA to determine whether previously reported behavioral benefits supplied by similarity, proximity and uniform connectedness were reflected as a neural savings such that the CDA amplitude was reduced when these cues were present. We implemented VWM change detection tasks with arrays including similarity and proximity (Experiment 1); uniform connectedness (Experiments 2a and 2b); similarity/proximity and uniform connectedness (Experiment 3). The results indicated that when there was a behavioral benefit to VWM, this was echoed by a reduction in CDA amplitude, which suggests more efficient processing. However, not all perceptual grouping cues provided a VWM benefit in the same measure (e.g., accuracy) or of the same magnitude. We also found unexpected interactions between cues. We observed a mixed bag of effects, suggesting that these powerful perceptual grouping benefits are not as predictable in VWM. The current findings indicate that, when grouping cues produce behavioral benefits, there is a parallel reduction in the neural resources required to maintain grouped items within VWM. PMID:26018644

  11. Scaffolded Active Learning: Nine Pedagogical Principles for Building a Modern Veterinary Curriculum.

    May, Stephen A; Silva-Fletcher, Ayona

    2015-01-01

    Veterinary discipline experts unfamiliar with the broader educational literature can find the adoption of an evidence-based approach to curriculum development challenging. However, greater societal and professional demands for achieving and verifying Day One knowledge and skills, together with continued progress in information generation and technology, make it all the more important that the defined period for initial professional training be well used. This article presents and discusses nine pedagogical principles that have been used in modern curricular development in Australia, the United Kingdom, and the United States: (1) outcomes-based curriculum design; (2) valid and reliable assessments; (3) active learning; (4) integrated knowledge for action; (5) tightly controlled core curriculum; (6) "just-in-time" rather than "just-in-case" knowledge; (7) vertical integration, the spiral curriculum, and sequential skills development; (8) learning skills support; and (9) bridges from classroom to workplace. Crucial to effective educational progress is active learning that embraces the skills required by the modern professional, made possible by tight control of curricular content. In this information age, professionals' ability to source information on a "just-in-time" basis to support high quality reasoning and decision making is far more important than the memorization of large bodies of increasingly redundant information on a "just-in-case" basis. It is important that those with responsibility for veterinary curriculum design ensure that their programs fully equip the modern veterinary professional for confident entry into the variety of roles in which society needs their skills.

    Full Text Available Abstract Background Thymoquinone is an active principle of Nigella sativa seed known as "Habbah Al-Sauda" in Arabic countries and "Sinouj" in Tunisia. Bacterial biofilms tend to exhibit significant tolerance to antimicrobials drugs during infections. Methods The antibacterial activity of Thymoquinone (TQ and its biofilm inhibition potencies were investigated on 11 human pathogenic bacteria. The growth and development of the biofilm were assessed using the crystal violet (CV and the 2, 3-bis [2-methyloxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxanilide (XTT reduction assay. Results TQ exhibited a significant bactericidal activity against the majority of the tested bacteria (MICs values ranged from 8 to 32 μg/ml especially Gram positive cocci (Staphylococcus aureus ATCC 25923 and Staphylococcus epidermidis CIP 106510. Crystal violet assay demonstrated that the minimum biofilm inhibition concentration (BIC50 was reached with 22 and 60 μg/ml for Staphylococcus aureus ATCC 25923 and Staphylococcus epidermidis CIP 106510 respectively. In addition our data revealed that cells oxidative activity was influenced by TQ supplementation. In the same way, TQ prevented cell adhesion to glass slides surface. Conclusion The ability of TQ to prevent biofilm formation warrants further investigation to explore its use as bioactive substances with antibiofilm potential.

    A technical and economical feasibility study was performed comparing the use electron beam and activated charcoal for treatment of industrial wastewater. In this study was used synthetic solutions, prepared in laboratory with organic compounds standards, where the composition was focused on the critical organic contaminants usually presented in wastewater from petrochemical industry. For the sample irradiation was used an industrial electron beam from Radiation Dynamics Inc. 1.5 MeV - 37.5 kW setup in IPEN. The doses ranged from 5 kGy to 100 kGy. A common granulated activated charcoal in a fixed-bed absorber glass column was used to study the pollutants absorption performance. The results show that if the adequate irradiation dose was delivered to the organic pollutant, it is possible to conclude for the studied compounds that the Electron Beam Process is, in aspect of organic removal efficiency, similar to the activated carbon process.

    Efficacy of Allium cepa test system for screening cytotoxicity and genotoxicity of treated effluents originated from four types of industrial activities (two textile industries, three rubber based industries, two common treatment plants of industrial zones, and two water treatment plants) was assessed. Physico-chemical parameters including the heavy metal/metalloid levels of the effluents varied depending on the industry profile, but most of the measured parameters in the effluents were within the specified tolerance limits of Sri Lankan environmental regulations for discharge of industrial effluents into inland surface waters. In the A. cepa test system, the undiluted effluents induced statistically significant root growth retardation, mitosis depression, and chromosomal aberrations in root meristematic cells in most cases in comparison to the dilution water and upstream water signifying effluent induced cytotoxicity and genotoxicity. Ethyl methane sulphonate (a mutagen, positive control) and all the effluents under 1:8 dilution significantly induced total chromosomal aberrations in root meristematic cells in comparison to the dilution water and upstream water indicating inadequacy of expected 1:8 dilutions in the receiving waters for curtailing genotoxic impacts. The results support the use of a practically feasible A. cepa test system for rapid screening of cytotoxicity and genotoxicity of diverse industrial effluents discharging into inland surface waters.

  16. Overview of non-pharmacological intervention for dementia and principles of brain-activating rehabilitation.

    Non-pharmacological interventions for dementia are likely to have an important role in delaying disease progression and functional decline. Research into non-pharmacological interventions has focused on the differentiation of each approach and a comparison of their effects. However, Cochrane Reviews on non-pharmacological interventions have noted the paucity of evidence regarding the effects of these interventions. The essence of non-pharmacological intervention is dependent of the patients, families, and therapists involved, with each situation inevitably being different. To obtain good results with non-pharmacological therapy, the core is not 'what' approach is taken but 'how' the therapists communicate with their patients. Here, we propose a new type of rehabilitation for dementia, namely brain-activating rehabilitation, that consists of five principles: (i) enjoyable and comfortable activities in an accepting atmosphere; (ii) activities associated with empathetic two-way communication between the therapist and patient, as well as between patients; (iii) therapists should praise patients to enhance motivation; (iv) therapists should try to offer each patient some social role that takes advantage of his/her remaining abilities; and (v) the activities should be based on errorless learning to ensure a pleasant atmosphere and to maintain a patient's dignity. The behavioral and cognitive status is not necessarily a reflection of pathological lesions in the brain; there is cognitive reserve for improvement. The aim of brain-activating rehabilitation is to enhance patients' motivation and maximize the use of their remaining function, recruiting a compensatory network, and preventing the disuse of brain function. The primary expected effect is that patients recover a desire for life, as well as their self-respect. Enhanced motivation can lead to improvements in cognitive function. Amelioration of the behavioral and psychological symptoms of dementia and improvements in

    Although China ratified the WHO Framework Convention on Tobacco Control [FCTC] in 2005, the partial ban on tobacco advertising does not cover the internet. Weibo is one of the most important social media channels in China, using a format similar to its global counterpart, Twitter. The Weibo homepage is a platform to present products, brands and corporate culture. There is great potential for the tobacco industry to exploit Weibo to promote products. Seven tobacco industry Weibo accounts that each had more than 5000 fans were selected to examine the content of Weibos established by tobacco companies or their advertising agents. Of the 12073 posts found on the seven accounts, 92.3% (11143) could be classified into six main themes: traditional culture, popular culture, social and business affairs, advertisement, public relations and tobacco culture. Posts under the theme of popular culture accounted for about half of total posts (49%), followed by 'advertisement' and 'tobacco culture' (both at 12%), 'traditional culture' and 'public relations' (both at 11%), and finally 'social and business affairs' (5%). 33% of posts included the words 'cigarette' or 'smoking' and 53% of posts included the tobacco brand name, indicating that tobacco companies carefully construct the topic and content of posts. Weibo is an important new online marketing tool for the Chinese tobacco industry. Tobacco industry use of Weibo to promote brands and normalize smoking subverts China's ratification of the WHO FCTC. Policy to control tobacco promotion needs reforming to address this widespread circumvention of China's tobacco advertising ban.

  14. Chinese tobacco industry promotional activity on the microblog Weibo.

    Directory of Open Access Journals (Sweden)

    Fan Wang

    Full Text Available BACKGROUND: Although China ratified the WHO Framework Convention on Tobacco Control [FCTC] in 2005, the partial ban on tobacco advertising does not cover the internet. Weibo is one of the most important social media channels in China, using a format similar to its global counterpart, Twitter. The Weibo homepage is a platform to present products, brands and corporate culture. There is great potential for the tobacco industry to exploit Weibo to promote products. METHODS: Seven tobacco industry Weibo accounts that each had more than 5000 fans were selected to examine the content of Weibos established by tobacco companies or their advertising agents. RESULTS: Of the 12073 posts found on the seven accounts, 92.3% (11143 could be classified into six main themes: traditional culture, popular culture, social and business affairs, advertisement, public relations and tobacco culture. Posts under the theme of popular culture accounted for about half of total posts (49%, followed by 'advertisement' and 'tobacco culture' (both at 12%, 'traditional culture' and 'public relations' (both at 11%, and finally 'social and business affairs' (5%. 33% of posts included the words 'cigarette' or 'smoking' and 53% of posts included the tobacco brand name, indicating that tobacco companies carefully construct the topic and content of posts. CONCLUSIONS: Weibo is an important new online marketing tool for the Chinese tobacco industry. Tobacco industry use of Weibo to promote brands and normalize smoking subverts China's ratification of the WHO FCTC. Policy to control tobacco promotion needs reforming to address this widespread circumvention of China's tobacco advertising ban.

    Full Text Available The study investigated relationships between agricultural policy output (proxy by the agricultural productivity index, agricultural GDP/total GDP and crop productivity index and output of industrial sector (proxy by the industrial capacity utilization rate from 1970 to 2012 period in Nigeria. The study employed time series variables obtained from the Central Bank of Nigeria (CBN, National Bureau of Statistics and Food and Agricultural Organization (FAO. Augmented Dickey-Fuller unit root test was conducted on the specified time series, and the result showed that all non-growth rate series were integrated of order one, while growth rate series were stationary at level. The two-step Engle Granger method was employed to test for the presence of cointegration among specified variables. The result revealed that variables were not co-integrated. To avoid spurious regression, the specified models for non-growth rate series were estimated at first difference of the log variables. The empirical result revealed that, the industrial activities Granger cause crop activities in Nigeria. Also, the industrial activity has insignificant relationship with agricultural productivity indices in Nigeria. The same result was also obtained for industrial activities and agricultural GDP/total GDP. However, the result further revealed that, the industrial activity has significant negative correlation with the crop productivity index in Nigeria. These imply that, agricultural production had not played significant role in industrial development in Nigeria. This result suggests that, there is no significant impact of the backward integration policy of the agricultural sector on industrial sector in Nigeria. In addition, the result revealed that, agricultural policies during liberalization era (1986 - 2012 shifted the coefficient of the industrial activities positively. Therefore, it is recommended that the agricultural production in Nigeria should be boosted so as to

    Propolis is produced by bees and is reported to have several pharmaceutical properties. Its antibacterial activity against strains causing upper respiratory tract infections is particularly important: propolis might be used as a therapeutic agent to prevent the bacterial infections that sometimes overlap viral infections. In this study the in vitro activity of both an alcoholic solution and a hydroglyceric extract of propolis, as well as its active principles, was tested against bacteria responsible for respiratory infections (Streptococcus pneumoniae, Haemophilus influenzae, Haemophilus parainfluenzae, Moraxella catarrhalis and Streptococcus pyogenes). We also evaluated the in vitro activity of a combination of propolis and its active principles and some beta-lactams, macrolides and fluoroquinolones. Our results, though not demonstrating a clearly synergistic activity between antibiotics and propolis and its constituents, show the possibility of using natural preparations, due to their antimicrobial and anti-inflammatory properties, to enhance antibacterial therapy.

    Timely estimation of deviations from optimal performance in complex systems and the ability to identify corrective measures in response to the estimated parameter deviations has been the subject of extensive research over the past four decades. The implications in terms of lost revenue from costly industrial processes, operation of large-scale public works projects and the volume of the published literature on this topic clearly indicates the significance of the problem. Applications range from manufacturing industries (integrated circuits, automotive, etc.), to large-scale chemical plants, pharmaceutical production, power distribution grids, and avionics. In this project we investigated a new framework for building parsimonious models that are suited for diagnosis and fault estimation of complex technical systems. We used Support Vector Machines (SVMs) to model potentially time-varying parameters of a First-Principles (FP) description of the process. The combined SVM & FP model was built (i.e. model parameters were trained) using constrained optimization techniques. We used the trained models to estimate faults affecting simulated beam lifetime. In the case where a large number of process inputs are required for model-based fault estimation, the proposed framework performs an optimal nonlinear principal component analysis of the large-scale input space, and creates a lower dimension feature space in which fault estimation results can be effectively presented to the operation personnel. To fulfill the main technical objectives of the Phase I research, our Phase I efforts have focused on: (1) SVM Training in a Combined Model Structure - We developed the software for the constrained training of the SVMs in a combined model structure, and successfully modeled the parameters of a first-principles model for beam lifetime with support vectors. (2) Higher-order Fidelity of the Combined Model - We used constrained training to ensure that the output of the SVM (i.e. the

    With the recent rapid industrialization, occupational safety and health (OSH) has become an important issue in all industrial and human activities. However, incidents of injuries and fatality rates in the Ghanaian industry sector continue to increase. Despite this increase, there is no evidence regarding the element of OSH management in transport activities in Ghanaian industries. Thus, this study aims to examine the perceptions regarding the importance of safety and health in work-related transport activities in Ghanaian industries. A survey data collection technique was used to gather information on best safety practices over a 5-month period. We randomly selected 298 respondents from industries to answer structured questionnaires. The respondents included drivers, transport managers, and safety engineers. Standard multiple regression model and Pearson product-movement correlation were used to performed the analysis. The result shows that for interventions to improve safety and health, concentration has been on drivers' safety practice with less attention to safe driving environments and vehicle usage. Additionally, the respondents are aware of the importance of OSH in transport activities, but the level of integration does not measure up to the standard to reduce operational accidents and injuries. Finally, strong commitment to changing unsafe practices at all levels of operations appears to be the effective way to improve safety situations. OSH culture is not fully complied in industries transport activities. This study, therefore, supports the use of safety seminars and training sessions for industry workers responsible for transport operations for better integration of safety standards.

    This work presents a method of information fusion involving data captured by both a standard charge-coupled device (CCD) camera and a time-of-flight (ToF) camera to be used in the detection of the proximity between a manipulator robot and a human. Both cameras are assumed to be located above the work area of an industrial robot. The fusion of colour images and time-of-flight information makes it possible to know the 3D localization of objects with respect to a world coordinate system. At the same time, this allows to know their colour information. Considering that ToF information given by the range camera contains innacuracies including distance error, border error, and pixel saturation, some corrections over the ToF information are proposed and developed to improve the results. The proposed fusion method uses the calibration parameters of both cameras to reproject 3D ToF points, expressed in a common coordinate system for both cameras and a robot arm, in 2D colour images. In addition to this, using the 3D information, the motion detection in a robot industrial environment is achieved, and the fusion of information is applied to the foreground objects previously detected. This combination of information results in a matrix that links colour and 3D information, giving the possibility of characterising the object by its colour in addition to its 3D localisation. Further development of these methods will make it possible to identify objects and their position in the real world and to use this information to prevent possible collisions between the robot and such objects.

    Nowadays development of construction in Malaysia has been effect to the increasing of construction waste. Additionally, the production of construction waste from construction projects has given negative impact to the environment especially in illegal dumping activities. The increasing number of illegal dumping activities from construction projects in Malaysia gives a sign that Malaysian construction waste management needs to be concerned. To date, a comprehensive criterion for construction waste management, particularly for a construction project in developing countries is still not clearly defined. Therefore, construction waste management in Malaysia needs further research. The objectives of this paper are to explore illegal dumping activities, and discuss the contributory factors of illegal dumping activities. Hence, this research conducted an interview with expertise in the area of construction waste management in order to scrutinise illegal dumping activities in Malaysia. The data from semistructured interviews were analysed by content analysis. Findings from this research will help to find out the strategies to reduce the illegal dumping activities. The final result also expected to increase the awareness and better solution for reducing illegal dumping activities in construction projects among construction players.

    2015-01-01

    The activated sludge process is an old technology, but still the most commonly used one for treatment of wastewater. Despite the wide spread usage the technology still suffers from instability (Tandoi et al. 2006) and high operating cost. Activated sludge processes often carry a large solids inventory. Managing the total inventory without interference is the key component of the optimization process described in this paper. Use of nutrients is common in pulp and paper effluent treatment. Feeding enough nutrients to support the biomass growth is a delicate balance. Overfeeding or underfeeding of nutrients can result in higher costs. Detrimental substances and toxic components in effluents entering a biological treatment system can cause severe, long lasting disturbances (Hynninen & Ingman 1998; Bergeron & Pelletier 2004). A LumiKem test kit is used to measure biological activity with adenosine triphosphate (ATP) in a pulp and paper mill. ATP data are integrated with other standardized mill parameters. Measurements of active volatile suspended solids based on ATP can be used to quantify the living biomass in the activated sludge process and to ensure that sufficient biomass is present in order to degrade the wastewater constituents entering the process. Information about active biomass will assist in optimizing sludge inventories and feeding of nutrients allowing the living biomass to re-populate to create optimal efficiency. ATP measurements can also be used to alert operators if any components toxic to bacteria are present in wastewater. The bio stress index represents the stress level experienced by the microbiological population. This parameter is very useful in monitoring toxicity in and around bioreactors. Results from the wastewater process optimization and ATP measurements showed that treatment cost could be reduced by approximately 20-30% with fewer disturbances and sustained biological activity compared to the reference period. This was mainly achieved by

    Industry has played a complex role in the rise of tobacco-related diseases in the United States. The tobacco industry's activities, including targeted marketing, are arguably among the most powerful corporate influences on health and health policy. We analyzed over 400 internal tobacco industry documents to explore how, during the past several decades, the industry targeted inner cities populated predominantly by low-income African American residents with highly concentrated menthol cigarette marketing. We study how major tobacco companies competed against one another in menthol wars fought within these urban cores. Little previous work has analyzed the way in which the inner city's complex geography of race, class, and place shaped the avenues used by tobacco corporations to increase tobacco use in low-income, predominantly African American urban cores in the 1970s-1990s. Our analysis shows how the industry's activities contributed to the racialized geography of today's tobacco-related health disparities.

    Full Text Available Drought, floods, damaging storms, heat waves, acid rain, climate changes are but a few of the consequences of human action upon the environment. Can we possibly live against the environment? The answer is NO, and as such we must run an economy which respects the principles of eco-efficiency because only so can economic progress go on. Green economy is a great opportunity for all of the world’s countries, and is a real economy which keeps the resource-needs and environment relation in balance, aims towards quality and not quantity, lays emphasis on regeneration, recycling, reuse and creativity. Eco-efficiency implies both innovation towards a high degree of product dematerialization, services and systems, alongside with greatly changing current production and consumption practices. If we produce based on the principle of eco-efficiency we can reduce the effects of the profound economic, ecological, socio-political and cultural-spiritual crisis which marks our planet and countries.

    The medicinal plant, Piper amalago L. (Piperaceae), is used traditionally by Q'eqchi' Maya healers for the treatment of "susto" a culture-bound syndrome. Previous research suggests that susto symptoms may be a manifestation of anxiety. The objectives were to characterize the effect of ethanolic extract of P. amalago in behavioral assays of anxiety at doses representative of traditional use and to isolate active principles. Rats treated orally with low dose ethanolic extracts of P. amalago leaves (8-75mg/kg) were tested in several behavioral paradigms including the elevated plus maze (EPM), social interaction (SI), and conditioned emotional response (CER) tests, and compared to diazepam, a positive control. The active anxiolytic principle was isolated by bioassay guided isolation using an in vitro GABAA competitive binding assay. Extracts had significant anxiolytic activity in all behavioral tests, with the strongest activity in the SI and the CER paradigms. In an in vitro GABAA competitive binding assay, a 66.5µg/mL concentration of P. amalago ethanol extract displaced 50% of the GABAA-BZD receptor ligand [(3)H]-Flunitrazepam. Bioassay-guided fractionation identified a furofuran lignan, a molecule with structural similarity to yangambin, with high affinity for the GABAA-BZD receptor as the principle bioactive. The results suggest that the ethnobotanical use of this plant may have a pharmacological basis in its anxiolytic activity, as demonstrated in animal behaviour tests.

    The prevalence of rhinosinusitis is quite high. Despite the widespread use of antibiotics for rhinosinusitis, there are other forms of treatment, including phytotherapy. One of the most widely used herbal medicines for treatment of rhinosinusitis is Luffa operculata. This study aimed to evaluate the efficacy of topical nasal solution of the aqueous extract of L. operculata, determining the toxicity to its use and identifying the active principles presented in the aqueous extract. The secondary objective was to evaluate the action of active principles on bacteria commonly involved in acute rhino sinusitis. The study was conducted in experimental model of sinusitis. Three different concentrations of L. operculata were used as local treatment of rhino sinusitis. The results were compared with those observed in control groups that received nasal saline solution. Histological examination of the liver, kidney, spleen, myocardium, brain and lungs of all animals evaluated the toxicity of L. operculata. The aqueous extract used was subjected to chromatographic analysis and an active principle was isolated and tested for in vitro inhibition of bacterial colonies usually found in rhino sinusitis. Intranasal treatment of sinusitis with L. operculata showed better clinical evolution than control group. Statistically significant difference (p>0.10) between the treated group and the control group was observed in the histologic evaluation for inflammatory pattern. The aqueous extract of L. operculata used presented a predominance of 2,3-dicafeoilglicaric acid, a substance not yet described in the literature. There was a significant difference in bacterial growth of Streptococcus pyogenes on blood-agar plates when under the influence of both the aqueous extract and the active substance. Topical nasal solution of the aqueous extract of L. operculata is effective compared to the application of saline solution for the treatment of bacterial rhinosinusitis in an experimental model. L

    2013-01-01

    We aimed to study the development and implementation of promotion of physical activity in a rural community by applying the principles of social marketing and to determine participation behaviour in a physical activity programme in a community setting. The intervention targeted 485 people, 20-49 years of age, residents of Periakattupalayam and Rangareddipalayam villages, Tamil Nadu. This community-based participatory research was based on the principles of 'social marketing'. Health education by one-to-one counselling, written materials and community events were used to popularize moderate intensity physical activity (brisk walking for 30 minutes on 4 days/week). We formed 30 walking groups under four coordinators, in a home-based setting with professional supervision and guidance. A log of physical activity sessions for the 10-week intervention period was maintained in the form of group attendance record. Village leaders, self-help groups and youth clubs were involved in promoting physical activity. Of the 485 subjects, 265 people (54.6%) engaged in brisk walking >4 days a week, while 156 subjects (32.2%) performed walking on 1-4 days per week during the intervention. The drop-out rate was 13.2% (64 subjects). Age, occupation and educational status were important determinants of participation and adherence to the physical activity programme. Application of social marketing techniques in an intervention to promote physical activity was successful in a rural Indian community. Studying the determinants of adoption of a physical activity programme and addressing the barriers to behaviour change are essential for designing relevant policies and effective programmes.

    1996-01-01

    Thermal and epithermal non-destructive activation analyses have been performed on samples of final molasses from 14 different sugar factories , covering the most important regions in Cuba. From the first measurement after irradiation at the Triga Mark reactor (VTT), the concentration of more than 15 elements is reported. The almost constant elemental composition shows that they can be used equally for different purposes as animal foodstuff and for the manufacture of biotechnological products. This work is part of a research project developed in order to establish a complete characterization of Cuban sugar molasses. (author). 7 refs., 2 tabs

    Benassi, Enrico; Corni, Stefano

    2012-09-01

    Azobenzene (di-phenyl-diazene) is well-known as a photoisomerisable molecule and has been widely studied as a molecular photoswitcher. Molecular rods, where di-phenyl arms are bound to the diazene moiety, have been also synthesized. In this article we explore by first principle density functional theory calculations the chiroptical properties (electronic circular dichroism spectra, ECD) of azobenzene and its homologues with polyphenyl arms. In particular, we demonstrate that for molecules in the cis configuration the intrinsic chirality of the distorted cis diazene group dominates the ECD response, while for trans species the non-planarity of the polyphenyl arms induces peaks in the ECD spectrum. Finally, the possibility of obtaining a light-controlled chiral switch by proper functionalization is also speculated.

    Babor, Thomas F; Robaina, Katherine

    2013-02-01

    We explored the emerging relationships among the alcohol industry, academic medicine, and the public health community in the context of public health theory dealing with corporate social responsibility. We reviewed sponsorship of scientific research, efforts to influence public perceptions of research, dissemination of scientific information, and industry-funded policy initiatives. To the extent that the scientific evidence supports the reduction of alcohol consumption through regulatory and legal measures, the academic community has come into increasing conflict with the views of the alcohol industry. We concluded that the alcohol industry has intensified its scientific and policy-related activities under the general framework of corporate social responsibility initiatives, most of which can be described as instrumental to the industry's economic interests.

    2011-01-01

    This work has the aim to employ the agave bagasse, a waste from Tequila and Mescal industries, to obtain a product of high commercial value such as activated carbon. The activated carbon production methodology was based on a chemical activation, by using ZnCl 2 and H 3 PO 4 as activating agent and agave bagasse as a natural source of carbon. The activation temperature (150-450 o C), activation time (0-60 min) and weight ratio of activating agent to precursor (0.2-4) were studied. The produced carbon materials were characterized by scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and nitrogen physisorption at -196 o C. In addition, the activating agent recovery was evaluated. We were able to obtain highly microporous activated carbons with micropore volumes between 0.24 and 1.20 cm 3 /g and a surface area within 300 and 2139 m 2 /g. These results demonstrated the feasibility to treat the industrial wastes of the Tequila and Mescal industries, being this wastes an excellent precursor to produce highly microporous activated carbons that can be processed at low activation temperatures in short times, with the possibility of recycling the activating agent.

    2009-01-01

    Respiratory muscles with dual respiratory and non-respiratory functions (e.g. the pharyngeal and intercostal muscles) show greater suppression of activity in sleep than the diaphragm, a muscle almost entirely devoted to respiratory function. This sleep-related suppression of activity is most apparent in the tonic component of motor activity, which has functional implications of a more collapsible upper airspace in the case of pharyngeal muscles, and decreased functional residual capacity in t...

    Full Text Available This article examines differences in an impact of business cycle phases on innovation activity in medium-high and high technology industry in Poland. It is assumed that each business cycle phase influences innovation activity in the same fashion, but its impact varies and it depends on the firm’s innovation activity. The higher innovation activity the less impact of business cycle. The scope of the survey relates to innovation in MHT and HT industry in Poland. The data concerns the innovation at the firm level and the diffusion “new for the company”. Innovation activity is defined by the following activities: (1 expenditure on research and development and investments in fixed assets not used so far such as: abuildings, premises and land; b machinery and equipment, c computer software; (2 implementation of new products and technological processes and (3 innovation cooperation. The methodological part of the analysis includes a logit modeling. The survey includes 1355 companies. Business cycle has a great influence on innovation activity in MTH and HT industry in Poland. The influence of recovery phase is positive whereas both stagnation and recession phases decrease the probability of innovation activity. The character of influence depends on the propensity to take innovation activity. The higher level of innovation activity the enterprises present the less influence of business cycle they get.

The capacitive current detection needed in them suffers from low accuracy and robustness...

  18. Socio-economic benefits from petroleum industry activity in Newfoundland and Labrador 2003 and 2004

    International Nuclear Information System (INIS)

    2005-11-01

    An update on previous macroeconomic analyses of the impacts of offshore petroleum activities in Newfoundland and Labrador was presented. Details of industry activity and expenditures in Newfoundland and Labrador were presented as well as the resultant direct, indirect and induced economic benefits to the province. Related developments in infrastructure, education, training, and research and development were also provided. It was observed that there was a further consolidation and expansion of the offshore petroleum industry in the province as well as additional growth in its contribution to the province's economy. By 2004, the petroleum industry was responsible for nearly 25 per cent of the province's GDP, with total labour income being 12 per cent higher than it would have been without offshore petroleum industry activity. Significant positive effects were noted in retail sales, the unemployment rate, housing starts and the size of the provincial population. Production activity has become increasingly important, and there has been increased involvement of local companies and individuals in export work, indicating that the petroleum industry is making an important contribution to economic diversification and sustainability. New offshore petroleum activities included the Hebron oilfield project; satellite field developments in the Jeanne d'Arc Basin; exploration in the Orphan Basin and Laurentian Sub-basin; and the development of natural gas reserves using compressed natural gas (CNG) or alternative transportation strategies. Infrastructure, education, training and research and development activities were outlined. It was noted that the low level of exploration in 2003 and 2004 was a matter of concern. It was concluded that a failure to proceed with more recent development projects would be a major blow to the local petroleum industry and the economy as a whole. 2 refs., 2 tabs., 1 fig

    To describe a system that uses off-the-shelf sensor and telecommunication technologies to continuously measure individual lifespace and activity levels in a novel way. Proof of concept involving three field trials of 30, 30, and 21 days. Omaha, Nebraska, metropolitan and surrounding rural region. Three participants (48-year-old man, 33-year-old woman, and 27-year-old male), none with any functional limitations. Cellular telephones were used to detect in-home position and in-community location and to measure physical activity. Within the home, cellular telephones and Bluetooth transmitters (beacons) were used to locate participants at room-level resolution. Outside the home, the same cellular telephones and global positioning system (GPS) technology were used to locate participants at a community-level resolution. Physical activity was simultaneously measured using the cellular telephone accelerometer. This approach had face validity to measure activity and lifespace. More importantly, this system could measure the spatial and temporal organization of these metrics. For example, an individual's lifespace was automatically calculated across multiple time intervals. Behavioral time budgets showing how people allocate time to specific regions within the home were also automatically generated. Mobile monitoring shows much promise as an easily deployed system to quantify activity and lifespace, important indicators of function, in community-dwelling adults. © 2011, Copyright the Authors.

    Two exploratory clinical studies investigating proprietary pomegranate products showed a trend of effectiveness in increasing prostate-specific antigen doubling time in patients with prostate cancer. A recent clinical study did not support these results. We therefore analysed a lot of the marketed pomegranate blend for co-active pomegranate compounds. The high-performance liquid chromatography method was used to detect punicalagin, ellagic acid and anthocyanins. Total polyphenoles were determined by the Folin-Ciocalteu method using gallic acid as reference. The results show that the co-active compounds in the daily dose of the pomegranate blend were far below those previously tested and that the photometric assessment is not reliable for the standardisation of study medications. Not pomegranate but the low amount of co-active compounds in the proprietary pomegranate blend was responsible for its clinical ineffectiveness. Copyright © 2014 John Wiley & Sons, Ltd.

    Be it proteins, new superconductors, polymers or ferro-magnetic compounds, fundamental research is laying foundations for possible technical applications as well as industrial exploitation. At the ESRF, industrial companies can be involved in two main ways, depending on the type of research they are interested in. The first concerns beam time allocation for non-proprietary and fully-published research, the procedure is the same as for public laboratories. The second concerns the proprietary research, for which a fee is charged and where results are kept confidential. The use of synchrotron radiation for the characterisation of materials is certain to play a crucial role in the development of new materials in the close future. It is a policy of the ESRF that European industry should share the benefit of its facilities. A survey of the today industrial activity at the ESRF and of its perspective in near future is presented

    Zinc oxide (ZnO) nanostructures with different morphologies are prepared in the presence of surface active molecules such as sodium dodecyl sulphate (SDS), Tween 80 and Triton X-100 by a chemical method. The experimental and first principles methods are employed to understand the microscopic origin of the asymmetric growth mechanism of ZnO in the presence of various surface active molecules. Effect of increase in the amount of surface active molecules and temperature is studied on the growth morphology of ZnO. An innovative method is developed to synthesize ZnO nanowires (NWs) in the presence of SDS. Spherical nanoparticles (NPs) to spherical clusters are obtained in the presence of Triton X-100 and Tween 80. These results are then supported by first principles calculations. The adsorption of the -OH functional group on both polar and nonpolar surfaces of ZnO is modelled by using density functional theory (DFT). The calculated binding energy (BE) is almost equivalent on both the surfaces with no preference on any particular surface. The calculated value of BE shows that the -OH group is physio-adsorbed on both the surfaces. This results in the spherical morphology of nanoparticles prepared in the presence of Tween 80. Bader charge analysis shows that the charge transfer mainly takes place on top two layers of the ZnO(101[combining macron]0) surface. The absence of high values of electron localization function (ELF) reflects the lack of covalent bonding between the -OH group and the ZnO(101[combining macron]0) surface.

  4. The Policy Dystopia Model: An Interpretive Analysis of Tobacco Industry Political Activity.

    Science.gov (United States)

    2016-09-01

    Tobacco industry interference has been identified as the greatest obstacle to the implementation of evidence-based measures to reduce tobacco use. Understanding and addressing industry interference in public health policy-making is therefore crucial. Existing conceptualisations of corporate political activity (CPA) are embedded in a business perspective and do not attend to CPA's social and public health costs; most have not drawn on the unique resource represented by internal tobacco industry documents. Building on this literature, including systematic reviews, we develop a critically informed conceptual model of tobacco industry political activity. We thematically analysed published papers included in two systematic reviews examining tobacco industry influence on taxation and marketing of tobacco; we included 45 of 46 papers in the former category and 20 of 48 papers in the latter (n = 65). We used a grounded theory approach to build taxonomies of "discursive" (argument-based) and "instrumental" (action-based) industry strategies and from these devised the Policy Dystopia Model, which shows that the industry, working through different constituencies, constructs a metanarrative to argue that proposed policies will lead to a dysfunctional future of policy failure and widely dispersed adverse social and economic consequences. Simultaneously, it uses diverse, interlocking insider and outsider instrumental strategies to disseminate this narrative and enhance its persuasiveness in order to secure its preferred policy outcomes. Limitations are that many papers were historical (some dating back to the 1970s) and focused on high-income regions. The model provides an evidence-based, accessible way of understanding diverse corporate political strategies. It should enable public health actors and officials to preempt these strategies and develop realistic assessments of the industry's claims.

    2009-11-01

    The contemporary workplace setting is in need of interventions that effectively promote higher levels of occupational and habitual physical activity. It is the purpose of this paper to outline an evidence-based approach to promote physical activity in the business and industry sector in support of a National Physical Activity Plan. Comprehensive literature searches identified systematic reviews, comprehensive reviews, and consensus documents on the impact of physical activity interventions in the business and industry sector. A framework for action and priority recommendations for practice and research were generated. Comprehensive, multicomponent work-site programs that include physical activity components generate significant improvements in health, reduce absenteeism and sick leave, and can generate a positive financial return. Specific evidence-based physical activity interventions are presented. Recommendations for practice include implementing comprehensive, multicomponent programs that make physical activity interventions possible, simple, rewarding and relevant in the context of a social-ecological model. The business and industry sector has significant opportunities to improve physical activity among employees, their dependents, and the community at-large and to reap important benefits related to worker health and business performance.

    To prove that magnetic resonance imaging of foetal anatomy during the active second stage of vaginal delivery is feasible. Initially, five pregnant volunteers around the 30th week of gestation were examined in an open MRI. Based on the findings, one vaginal delivery was acquired under real-time imaging. To monitor the birth status during image acquisition, an MR-compatible wireless cardiotocography (CTG) system was built. Single-shot sequence parameters were optimised to compensate motion artefacts during labour. Safety requirements to monitor the birth process under real-time MR imaging were met. High-resolution MR images were acquired immediately before and after delivery. In one patient, TSE single-shot cinematic sequences of the active second stage of labour were obtained. All sequences were adapted to tolerate movement of the mother and infant, as well as residual noise from the CTG. Furthermore, the MR imaging during labour showed only minor image artefacts. CTG-monitored acquisition of MRI series during the active second stage of delivery is feasible. Image quality should allow various further studies to improve models for birth simulation as well as potential investigation of obstructed labour and obstetric complications. (orig.)

  9. Assessing participants' perceptions on group-based principles for action in community-based health enhancing physical activity programmes: The APEF tool.

    2017-12-01

    In community-based health enhancing physical activity (CBHEPA) programmes, group-based principles for action such as active participation, enjoyment, and fostering group processes are widely advocated. However, not much is known about participants' perceptions of these principles as there are no assessment tools available. Therefore, this article describes the development of the APEF (Active Participation, Enjoyment, and Fostering group processes) tool and reports on its implementation in a Dutch CBHEPA programme. Indicators for the principles have been identified from literature research, interviews with professionals, and secondary analysis of three group interviews with 11 practitioners. To address the identified indicators, the APEF tool was developed, pretested, and used in 10 focus groups with 76 participants. The APEF tool consists of eight statements about group-based principles for action, on which CBHEPA participants vote, followed by in-depth discussion. The voting procedure engages participants. Spider diagrams visualise participants' perceptions of group-based principles. The APEF tool addresses the challenge of relating group level outcomes to individual outcomes such as physical activity behaviour. The tool facilitates as well as evaluates group-based principles for action, it stimulates dialogue and is culturally sensitive, but it needs strong facilitating skills to manage group dynamics.

    The electronic structure and adsorption properties of 1.5 nm sized Pt, Au, and PtAu nanoclusters are studied by density functional theory. We explain the recent experimental finding that 20% Au content in PtAu nanoparticles is optimal to induce a dramatically different catalytic behavior. Our results show that the d-band center together with the density of states at the Fermi energy can be used as an indicator of the chemical activity of PtAu nanoclusters. The most favorable adsorption sites on the cluster surfaces as a function of the Pt/Au ratio are identified using atomic H as a probe.

    Full Text Available The paper considers the problem of interdisciplinarity as the main tendency of today’s science to unite the methodology and terminology and adapt them to any academic field in order to achieve more objective results in the study of complex phenomena. This article is a descriptive one and it deals with problems of terms’ interpretations and their adaptation to the anthropocentric research viewed by scientists of different academic schools. The main idea of the article is to find the most relevant and systemic definition of the given terms, which could be used as a tool in further linguistic analysis applied to the coming research of the authors. Special attention is paid to the description of the Activity Theory from different aspects of its interpretation: psychological, sociological, linguistic; to the explanation of the correlation between the epistemic structure of knowledge and an open non-linear synergetic bilateral (conceptual and lexical-semantic system influenced and motivated by processual factors to evolution in the modern discourse as the communicative activity of the interpreter and the constructor of discourse.

    Tetrahydrocurcumin (THC) is an antioxidative substance, which is derived from curcumin, the component of turmeric. In the present investigation, the effect of THC and curcumin against chloroquine (CQ) induced hepatotoxicity were studied in female Wistar rats. On single oral administration of CQ (970 mg/kg body weight) the activities of serum marker enzymes namely aspartate transaminase, alanine transaminase and alkaline phosphatase and the levels of bilirubin were significantly increased with significant alterations of lipids in serum and lipidperoxidation markers such as thiobarbituric acid reactive substances (TBARS) and hydroperoxides in plasma and liver were also elevated in CQ treated rats. The levels of non-enzymic antioxidants (vitamin C, vitamin E and reduced glutathione) and enzymic antioxidants (superoxide dismutase, catalase and glutathione peroxidase) were also decreased in CQ treated rats. Administration of THC (80 mg/kg body weight) and curcumin (80 mg/kg body weight) for 8 days before and 7 days after single administration of CQ significantly decreased the activities of serum markers and lipids in serum. In addition, the level of TBARS and hydroperoxides were significantly decreased with significant increase in non-enzymic and enzymic antioxidants on treatment with THC and curcumin. The biochemical observation was supplemented by histopathological examination of liver section. The results of the study reveal that THC shows more pronounced protective effect than curcumin against CQ induced toxicity.

    Streptozotocin-induced diabetic rats were maintained on 0.5% curcumin containing diet for 8 weeks. Blood cholesterol was lowered significantly by dietary curcumin in these diabetic animals. Cholesterol decrease was exclusively from LDL-VLDL fraction. Significant decrease in blood triglyceride and phospholipids was also brought about by dietary curcumin in diabetic rats. In a parallel study, wherein diabetic animals were maintained on a high cholesterol diet, the extents of hypercholesterolemia and phospholipidemia were still higher compared to those maintained on control diet. Curcumin exhibited lowering of cholesterol and phospholipid in these animals also. Liver cholesterol, triglyceride and phospholipid contents were elevated under diabetic conditions. Dietary curcumin showed a distinct tendency to counter these changes in lipid fractions of liver. This effect of curcumin was also seen in diabetic animals maintained on high cholesterol diet. Dietary curcumin also showed significant countering of renal cholesterol and triglycerides elevated in diabetic rats. In order to understand the mechanism of hypocholesterolemic action of dietary curcumin, activities of hepatic cholesterol-7a-hydroxylase and HMG CoA reductase were measured. Hepatic cholesterol-7a-hydroxylase activity was markedly higher in curcumin fed diabetic animals suggesting a higher rate of cholesterol catabolism.

  19. Can active learning principles be applied to the bioscience assessments of nursing students? A review of the literature.

    To explore if active learning principles be applied to nursing bioscience assessments and will this influence student perception of confidence in applying theory to practice? A review of the literature utilising searches of various databases including CINAHL, PUBMED, Google Scholar and Mosby's Journal Index. The literature search identified research from twenty-six original articles, two electronic books, one published book and one conference proceedings paper. Bioscience has been identified as an area that nurses struggle to learn in tertiary institutions and then apply to clinical practice. A number of problems have been identified and explored that may contribute to this poor understanding and retention. University academics need to be knowledgeable of innovative teaching and assessing modalities that focus on enhancing student learning and address the integration issues associated with the theory practice gap. Increased bioscience education is associated with improved patient outcomes therefore by addressing this "bioscience problem" and improving the integration of bioscience in clinical practice there will subsequently be an improvement in health care outcomes. From the literature several themes were identified. First there are many problems with teaching nursing students bioscience education. These include class sizes, motivation, concentration, delivery mode, lecturer perspectives, student's previous knowledge, anxiety, and a lack of confidence. Among these influences the type of assessment employed by the educator has not been explored or identified as a contributor to student learning specifically in nursing bioscience instruction. Second that educating could be achieved more effectively if active learning principles were applied and the needs and expectations of the student were met. Lastly, assessment influences student retention and the student experience and as such assessment should be congruent with the subject content, align with the learning

    2017-04-01

    To gain deeper insight into the corporate political activity (CPA) of the Australian food industry from a public health perspective. Fifteen interviews with a purposive sample of current and former policy makers, public health advocates and academics who have closely interacted with food industry representatives or observed food industry behaviours. All participants reported having directly experienced the CPA of the food industry during their careers, with the 'information and messaging' and 'constituency building' strategies most prominent. Participants expressed concern that food industry CPA strategies resulted in weakened policy responses to addressing diet-related disease. This study provides direct evidence of food industry practices that have the potential to shape public health-related policies and programs in Australia in ways that favour business interests at the expense of population health. Implications for public health: This evidence can inform policy makers and public health advocates and be used to adopt measures to ensure that public interests are put at the forefront as part of the policy development and implementation process. © 2017 The Authors.

  7. Current Status of Trace Metal Pollution in Soils Affected by Industrial Activities

    2012-01-01

    Full Text Available There is a growing public concern over the potential accumulation of heavy metals in soil, owing to rapid industrial development. In an effort to describe the status of the pollutions of soil by industrial activities, relevant data sets reported by many studies were surveyed and reviewed. The results of our analysis indicate that soils were polluted most significantly by metals such as lead, zinc, copper, and cadmium. If the dominant species are evaluated by the highest mean concentration observed for different industry types, the results were grouped into Pb, Zn, Ni, Cu, Fe, and As in smelting and metal production industries, Mn and Cd in the textile industry, and Cr in the leather industry. In most cases, metal levels in the studied areas were found to exceed the common regulation guideline levels enforced by many countries. The geoaccumulation index (Igeo, calculated to estimate the enrichment of metal concentrations in soil, showed that the level of metal pollution in most surveyed areas is significant, especially for Pb and Cd. It is thus important to keep systematic and continuous monitoring of heavy metals and their derivatives to manage and suppress such pollution.

    Ross, A.M.; Sokolsky, D.

    1995-05-01

    The project addressed in this report investigated the status of nuclear utility industry Cost Beneficial Licensing Action (CBLA) and Commitment Reduction (CR) activities. The CBLA program was a recent NRC initiative to enable utilities to revise regulatory commitments that have minimal safety impact and have but have been costly to implement. The project determined that approximately half of the utilities in the industry have formal programs to address this issue and that the programs implemented to date have had mixed results: some utilities benefited greatly and others only achieved minimal rewards. The project also determined that there are some significant factors that impact the potential for success of such programs. These factors include the level of management involvement and support, the level of resources dedicated to CBLA/CR activities, and the willingness of the utility to pursue issues that previously had not been considered. In addition, the overall success of the industry efforts will be highly dependent upon the effectiveness of the respective assigned NRR Project Manager, NRC's newly formed CBLA Task Group, and the NRC's ability to effect a mechanism to provide real value added for those submittals made to the Commission that are designated as CBLA submittals. It is anticipated that the next 12 months will be critical to the success or failure of industry CBLA/CR efforts as the industry begins to use an NEI process designed to facilitate the evaluation of CBLA/CR issues and the NRC CBLA Task Group begins to function in a routine manner

    Berry, Joel; Brangwynne, Clifford P.; Haataja, Mikko

    2018-04-01

    Exciting recent developments suggest that phase transitions represent an important and ubiquitous mechanism underlying intracellular organization. We describe key experimental findings in this area of study, as well as the application of classical theoretical approaches for quantitatively understanding these data. We also discuss the way in which equilibrium thermodynamic driving forces may interface with the fundamentally out-of-equilibrium nature of living cells. In particular, time and/or space-dependent concentration profiles may modulate the phase behavior of biomolecules in living cells. We suggest future directions for both theoretical and experimental work that will shed light on the way in which biological activity modulates the assembly, properties, and function of viscoelastic states of living matter.

    Clean production does not only make the sustainable development possible through preventing the deterioration of the environmental pollution from the expansion of industrialization but also enhance the company's competitiveness. Clean production is required by all industrial fields but is the most important in chemical industry. The Government has made efforts to change the domestic industrial structure to the environmental-friendly structure through developing the research. However, the domestic industry has not yet activated overall except some large companies, which has concretized the activation of clean production. Especially, the medium and small companies are more sluggish due to the inferiority of capital and technology. With recognizing that the main body of clean production is a company, the effort based on the Government and the academic world, without companies' positive, will cannot help being limited in effects. Therefore, it is necessary to trigger the schemes that urge the companies' motivation to show the effects from the support that have concentrated in hardware like technology until now. It seems to be very important that the guidebook for clean production, which a company can easily adopt, is developed and spread. This report provides the guidebook for clean production that managers and engineers can easily understand and approach in a producing field and presents the scheme to promote clean production, for chemical industry that is seriously required clean production. Even if the presented contents are not perfect, they can be applied to the development of the Government's policy and the administrative activities of companies for clean production as a useful data. 53 refs., 5 figs., 30 tabs.

  13. QSAR prediction of estrogen activity for a large set of diverse chemicals under the guidance of OECD principles.

    2006-11-01

    A large number of environmental chemicals, known as endocrine-disrupting chemicals, are suspected of disrupting endocrine functions by mimicking or antagonizing natural hormones, and such chemicals may pose a serious threat to the health of humans and wildlife. They are thought to act through a variety of mechanisms, mainly estrogen-receptor-mediated mechanisms of toxicity. However, it is practically impossible to perform thorough toxicological tests on all potential xenoestrogens, and thus, the quantitative structure--activity relationship (QSAR) provides a promising method for the estimation of a compound's estrogenic activity. Here, QSAR models of the estrogen receptor binding affinity of a large data set of heterogeneous chemicals have been built using theoretical molecular descriptors, giving full consideration to the new OECD principles in regulation for QSAR acceptability, during model construction and assessment. An unambiguous multiple linear regression (MLR) algorithm was used to build the models, and model predictive ability was validated by both internal and external validation. The applicability domain was checked by the leverage approach to verify prediction reliability. The results obtained using several validation paths indicate that the proposed QSAR model is robust and satisfactory, and can provide a feasible and practical tool for the rapid screening of the estrogen activity of organic compounds.

    Non-communicable diseases (NCDs) are the leading cause of mortality in Fiji, a middle-income country in the Pacific. Some food products processed sold and marketed by the food industry are major contributors to the NCD epidemic, and the food industry is widely identified as having strong economic and political power. However, little research has been undertaken on the attempts by the food industry to influence public health-related policies and programs in its favour. The "corporate political activity" (CPA) of the food industry includes six strategies (information and messaging; financial incentives; constituency building; legal strategies; policy substitution; opposition fragmentation and destabilisation). For this study, we aimed to gain a detailed understanding of the CPA strategies and practices of major food industry actors in Fiji, interpreted through a public health lens. We implemented a systematic approach to monitor the CPA of the food industry in Fiji for three months. It consisted of document analysis of relevant publicly available information. In parallel, we conducted semi-structured interviews with 10 stakeholders involved in diet- and/or public health-related issues in Fiji. Both components of the study were thematically analysed. We found evidence that the food industry adopted a diverse range of strategies in an attempt to influence public policy in Fiji, with all six CPA strategies identified. Participants identified that there is a substantial risk that the widespread CPA of the food industry could undermine efforts to address NCDs in Fiji. Despite limited public disclosure of information, such as data related to food industry donations to political parties and lobbying, we were able to identify many CPA practices used by the food industry in Fiji. Greater transparency from the food industry and the government would help strengthen efforts to increase their accountability and support NCD prevention. In other low- and middle-income countries, it

    The energetic effect of water substitution reactions in hexacoordinated [Mn(H 2 O) 6-n L z n ] 2+nz complexes with L = methanol, formic acid, formamide, formate, imidazole, and diphosphate is quantitatively analyzed at the MP2/triple-ζ level of theory. Subsequently, the state-of-the-art open shell symmetry-adapted perturbation theory (SAPT) analysis of the interaction energies of Mn 2+ ···ligand dimers with selected O-, S-, and N-binding ligands is presented and compared to similar interactions of Mg 2+ and Zn 2+ ions. We find that the induction energies in the dimers with manganese are almost twice as large as in dimers with magnesium. The total interaction energies rise in the order Mn 2+ < Mg 2+ < Zn 2+ . The calculations of the Mn 2+ → Mg 2+ replacement reaction suggest that metal-dependent glycosyltransferases influence the binding preference of Mn 2+ over Mg 2+ by inserting amino acids that coordinate the metal via nitrogen or sulfur into their active site.

Paradigma umum dalam melihat hukum acara perdata menempatkan Hakim bersifat pasif dalam menjalankan tugas dan fungsinya. Meskipun begitu terdapat keadaan-keadaan yang memposisikan hakim agar aktif menyelesaikan perkara perdata. Hal itu dapat terlihat pada penerapan Pasal 119 HIR pada saat Ketua Pengadilan Negeri memberikan bantuan berupa nasehat serta bantuan yang berhubungan dengan formalitas atau syarat-syarat gugatan agar gugatan dapat diterima dan memenuhi syarat-syarat formalitas gugatan kepada penggugat atau kuasanya. Selain itu, Pasal 130 HIR / Pasal 154 RBG, diwajibkan agar Ketua Pengadilan Negeri berusaha mendamaikan kedua belah pihak yang berperkara.

    2006-10-01

    Chronic hyperglycaemia in diabetes leads to the overproduction of free radicals and evidence is increasing that these contribute to the development of diabetic nephropathy. Among the spices, turmeric (Curcuma longa) is used as a flavouring and colouring agent in the indian diet every day and is known to possess anti-oxidant properties. The present study was designed to examine the effect of curcumin, a yellow pigment of turmeric, on renal function and oxidative stress in streptozotocin (STZ)-induced diabetic rats. Diabetes was induced by a single intraperitoneal injection of STZ (65 mg/kg) in rats. Four weeks after STZ injection, rats were divided into four groups, namely control rats, diabetic rats and diabetic rats treated with curcumin (15 and 30 mg/kg, p.o.) for 2 weeks. Renal function was assessed by creatinine, blood urea nitrogen, creatinine and urea clearance and urine albumin excretion. Oxidative stress was measured by renal malonaldehyde, reduced glutathione and the anti-oxidant enzymes superoxide dismutase and catalase. Streptozotocin-injected rats showed significant increases in blood glucose, polyuria and a decrease in bodyweight compared with age-matched control rats. After 6 weeks, diabetic rats also exhibited renal dysfunction, as evidenced by reduced creatinine and urea clearance and proteinuria, along with a marked increase in oxidative stress, as determined by lipid peroxidation and activities of key anti-oxidant enzymes. Chronic treatment with curcumin significantly attenuated both renal dysfunction and oxidative stress in diabetic rats. These results provide confirmatory evidence of oxidative stress in diabetic nephropathy and point towards the possible anti-oxidative mechanism being responsible for the nephroprotective action of curcumin.

  1. The transports in the French Plutonium Industry. A high risk activity

    Energy Technology Data Exchange (ETDEWEB)

    2003-02-01

    This study throws light on the scale of transport of plutonium in France nuclear industry, an activity involving quantities of high risk materials often unknown to the public. The study is a significantly extended update of the one carried out by WISE-Paris in 1995 for the Plutonium Forum. It was motivated by important developments in the French plutonium industry and the publication of numerous data concerning transport activities since 1995. The 2003 study presents, in particular, all of the flows of plutonium crossing France every year, as well as analysis of the risks associated with this particular transport activity. Putting these data into perspective in terms of a rapidly and permanently changing political and industrial context, and a description of the regulatory framework within which shipments of plutonium take place, serve as a guide and source of reference to help readers better understand the issues. The importance of transport in the plutonium ''chain'', i.e. the stages corresponding to various industrial processes, is often under-estimated, even by the nuclear industry itself. Transport is, in fact, the activity which involves the greatest quantities of plutonium in the entire nuclear chain. Plutonium, produced during the fission reactions in the cores of nuclear reactors, is transported, contained in the irradiated fuel, to the facilities at La Hague where reprocessing separates it from the other radioactive components of the spent fuel. Part of the plutonium, now isolated in powder form, is then shipped to one of the three plants able to produce the fuel known as MOX. These are located at Cadarache and Marcoule, in France, and at Dessel in Belgium. Once in the MOX form, this plutonium has to be re-transported to reactor sites to be used.

    The growing evidence on the association between consumption of sugar-sweetened beverages, obesity and other chronic diseases has highlighted the need to implement policy actions that go beyond programs exclusively focused on individual responsibility. In order to protect their commercial goals in Latin America, the sugar-sweetened beverage industry practices intense lobbying at high government levels in several countries across the region. This strategy is accompanied by corporate social responsibility programs that fund initiatives promoting physical activity. These efforts, although appearing altruistic, are intended to improve the industry's public image and increase political influence in order to block regulations counter to their interests. If this industry wants to contribute to human well being, as it has publicly stated, it should avoid blocking legislative actions intended to regulate the marketing, advertising and sale of their products.

    Full Text Available The dental erosion or decalcification of enamel is a significant clinical problem. Apple acidic beverages are thought to increase the potential for dental erosion. The purpose of this in vitro study was to investigate the effect of clove essential oil (CEO and its active principles on tooth decalcification of apple juices. On GC-MS analysis, CEO showed a high content of eugenol (58.29% and eugenyl acetate (19.10%. Teeth specimens were randomly divided into 5 treatment groups: control, CEO, eugenol, eugenyl-acetate, and fluoride. The specimens were exposed for 24 h and were analyzed for calcium contents using Inductively Coupled Plasma with Optical Emission Spectroscopy (ICP-OES. Data were analyzed using student t-test (<0.05. CEO, eugenol, and eugenyl-acetate significantly decreased the decalcification of tooth by the apple juice to only 17, 24, and 21 mgL−1, respectively. Hemolytic activity on human erythrocytes was studied to exclude the possibility of further associated cytotoxicity. It was observed that the CEO and its two lead molecules inhibit the decalcification and/or promote the remineralization caused by the apple juices. The effect of the test compounds appears to be distinct like that of fluoride treatment. CEO may, therefore, serve to be a promising adjunct to fluoride in the treatment of root caries during minimally invasive therapy.

  6. Effect of pressure on Zircon's (ZrSiO4) Raman active modes: a first-principles study

    Sheremetyeva, Natalya; Cherniak, Daniele; Watson, Bruce; Meunier, Vincent

    Zircon is a mineral commonly found in the Earth crust. Its remarkable properties have given rise to considerable attention. This includes possible inclusion of radioactive elements in natural samples, which allows for geochronological investigations. Subsequently, Zircon was proposed as possible host material for radioactive waste management. Internal radiation damage in zircon leads to the destruction of its crystal structure (an effect known as metamictization) which is subject to ongoing research. Recently, the effect of pressure and temperature on synthetic zircon has been analyzed experimentally using Raman spectroscopy which led to the calibration of zircon as a pressure sensor in diamond-anvil cell experiments. While there have been a number of theoretical studies, the effect of pressure on the Raman active modes of zircon has not been investigated theoretically. Here we present a first-principles pressure calibration of the Raman active modes in Zircon employing density-functional theory (DFT). We find excellent quantitative agreement of the slopes ∂ω / ∂P with the experimental ones and are able to rationalize the ω vs. P behavior based on the details of the vibrational modes.

    Full Text Available The currently available treatments for Chagas disease show limited therapeutic potential and are associated with serious side effects. Attempting to find alternative drugs isolated from Nature as agents against Trypanosoma cruzi has been our goal. Recently, we have demonstrated the in vitro anti-T. cruzi activities of two secondary metabolites isolated from the hydro-ethanolic extract of the aerial parts of Aristeguietia glutinosa (Lam., (family Asteraceae. These active principles displayed poor hemolytic activity, low toxicity against murine macrophages, and absence of mutagenicity. Herein, proof of concept in vivo studies of the whole hydro-ethanolic extract of the aerial parts of Aristeguietia glutinosa and of the most active component isolated from the hydro-ethanolic extract, i.e., (+-15-hydroxy-7-labden-17-al, was done in a murine acute model of Chagas disease. Both treatments caused a decrease in the animals’ parasitemia. Metabolomic mechanism of action studies were done by 1H-NMR, both on the extract and on the active compounds, examining the effects of the metabolites both on membrane sterol biosynthesis and mitochondrial dehydrogenases, whereby we found that one of the metabolites inhibited the activity of the parasite mitochondrial dehydrogenases and the other inhibited the biosynthesis of parasite membrane sterols. The results are interesting in the context of popular use of plants for the treatment of Chagas disease.

    2003-01-01

    Thin Layer Activation (TLA) technique is one of high-precision and effective nuclear methods for measurement and monitoring corrosion, erosion and wear on industrial components. This technique was developed by using low current charged particle beam produced from a cyclotron to activate a surface layer of component. In this case only the surface layer in the μm range at the desired parts of the component are activated. The surface activation lets a very low radioactivity concerning to safety aspect but still can be detected and measured well due to specificity and sensitivity of nuclear reaction produced. Some reported experiences on TLA technique have confirmed that the technique is proper fully recommended to be applied in various industries such as automotive, petrochemical, petroleum, power plant, transportation, lubricant oil etc. The measurement and monitoring of corrosion, erosion and wear rates can be remotely and continuously performed, on-line and in-situ, giving a real-time information. By giving a real-time information, TLA technique provides a considerably better estimation of the components lifetimes for any operating condition. The measurement sensitivity of surface loss rate by using this method can reach up to 0.01 μm depends on the type of applications. The application of the TLA technique lets early observation on the damage of the system preventing any disturbance on industrial process, either in the form of accident during the process or that of unscheduled interruption.

    Conventional cultivation methods and molecular approaches were utilised to describe the filamentous bacterial population of industrial activated sludge WWTPs. In total 43 strains were isolated by micromanipulation and were affiliated with 12 different species, comprising two new species and a new genus. In particular, a new species of Microthrix, a new genus of a filamentous Alphaproteobacteria morphologically similar to Nostocoida limicola, and a new filamentous species closely related to the opportunistic pathogen Propionibacterium propionicum were obtained. Despite the high number of isolates, the cultivation approach was unable to describe the filamentous bacteria most common in industrial WWTP. A culture-independent approach, termed the cell sorting/RT-PCR method, was therefore applied to identify fastidious or non-culturable filamentous microrganisms from different industrial plants. By this method the relevant filaments were micromanipulated and their 16S rDNA genes were amplified by RT-PCR. This approach was highly efficient. In total 31 16S rRNA sequences were obtained and 16 of them were used for the design of new specific oligonucleotide probes that highlighted dominant filaments in industrial activated sludge plants.

    The genus Iris is diverse both in the abundance of secondary metabolities as well as the biological activities. The rhizomes of Iris hookeriana exhibit significant anthelminthic activity against gastrointestinal nematodes of sheep. Although Iris hookeriana has been a subject of the study of so many phytochemical studies, yet we report some constituents for the first time from this plant using a different isolation approach. This manuscript presents the isolation, antimicrobial and antioxidant evaluation of bioactive principles from Iris hookeriana. LC-MS guided isolation technique was applied for the separation of target constituents. The isolates were characterised by spectral techniques and subjected to antioxidant evaluation by DPPH assay. Four compounds; resveratrol, resveratroloside, junipeginin C and isorhamnetin-3-O-neohesperidoside were isolated for the first time along with 3 known compounds viz piceid, irigenin and iridin from I. hookeriana using this approach. The antioxidant activity screening of the isolates revealed that all the 4 constituents isolated for the first time, have strong antioxidant potential with IC50 of 14.0 µg/ml (resveratroloside), 19.7 µg/ml (junipeginen C), 12.8 µg/ml (resveratrol) and 19.8 µg/ml (isorhamnetin-3-O-neohesperodoside). So it can be safely concluded that LC-MS guided isolation of chemical compounds from Iris hookeriana has furnished 4 antioxidant constituents. Thus Iris hookeriana can act as as a good source of wonder molecule resveratrol and its 2 glycosides, resveratrolside and piceid which upon hydrolysis can be converted into the parent drug resveratrol. © Georg Thieme Verlag KG Stuttgart · New York.

    In this study, reduction of estrogenic activity in three different types of effluents from sewage, industrial and livestock wastewater treatment plants by gamma-irradiation was investigated using the yeast two-hybrid assay. After gamma-ray treatment at a dose of 10 kGy, estrogenic activities of sewage, industrial and livestock effluents decreased from 4.4 to 3.0, 1.5 to 1.0 and 16 to 9.9 ng-EEQ L-1, respectively. The substantial reduction of estrogenic activity in livestock effluent was attributable to the degradation of 17β-estradiol (E2), estrone (E1) and 17α-ethynylestradiol (EE2). Although bisphenol A (BPA) was found at the highest concentration in all effluents, its contribution to the estrogenic activity was not significant due to its low relative estrogenic potency. Meanwhile, the calculated estrogenic activity based on concentrations of E2, E1, EE2 and BPA in the effluents significantly differed from the measured ones. Overestimation may have resulted by dissolved organic matters in effluents inhibiting the estrogenic activity of E2, E1, EE2 and BPA, whereas underestimation was likely due to estrogenic by-products generated by gamma-irradiation.

    Full Text Available The transition of Russia’s economy from raw materials exporting model of development to the innovation model is a national priority, since it contributes to intensive and sustainable economic growth and reduces economic dependence on external markets. GDP growth rate of 75–90% in the developed countries such as the USA, Japan, Germany, the UK, France, and also in the newly industrialized countries of Southeast Asia and China, is achieved due to the “progress of knowledge” – the intellectualization of the main production factors. Due to this fact, the increase in the standard of living in Russia, as well as overcoming its technological and economic lagging behind the more developed countries is possible only on the basis of the increase in productivity, enhancement of Russia’s competitiveness in international markets of innovative products, modernization and sustainable development of industrial enterprises through the creation of new innovation capabilities and the extensive utilization of that which have already been accumulated. The manufacturing industry is a powerful driving force of innovation economic development, since this sector concentrates the main production of the most technologically sophisticated and knowledgeintensive products with high added value. However, in the process of market transformations the products of domestic manufacturing enterprises have become much less competitive on international markets. There is a steady tendency toward the growth of imports and decrease of exports of enterprises of this sector. In this regard, the article identifies the factors that have the greatest influence on the development of innovation activities in the manufacturing industry. The author builds a multivariate regression model that determines the degree of influence of various socio-economic factors on the level of development of innovation activity in manufacturing.

    Despite the great number of substances produced by the skincare industry, very few of them seem to truly have an effect on the skin. Therefore, given the social implications surrounding physical appearance, the search for new bioactive compounds to prevent or attenuate skin ageing and enhance self-image is a priority of current research. In this context, being rich in valuable compounds, such as proteins, phenolics, lipids and vitamins, this study is focused on the potential activity of rapeseed press cake hydrolysates to be used as raw materials for skincare applications. In this study, the protein-rich press residue from the rapeseed oil industry was converted enzymatically into short-chain biologically active peptides using four protease products with varying substrate specificity - Alcalase 2.4L FG, Protex 6L, Protamex and Corolase 7089. The antioxidant, anti-wrinkle and anti-inflammatory activities of the obtained hydrolysates were evaluated in vitro while their biocompatibility with human skin fibroblasts was tested. All hydrolysates were biocompatible with skin fibroblasts after 24 h of exposure, while the non-hydrolysed extract induced cell toxicity. Alcalase 2,4L FG and Protex 6L-obtained hydrolysates were the most promising extracts showing improved bioactivities suitable for skin anti-ageing formulations, namely antioxidant activity, inhibiting approximately 80% cellular reactive oxidative species, anti-inflammatory and anti-wrinkle properties, inhibiting around 36% of myeloperoxidase activity and over 83% of elastase activity. The enzymatic technology applied to the rapeseed oil industry costream results in the release of bioactive compounds suitable for skincare applications. © 2015 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

    The oxidation process of boron (B) species on the Pt(111) surface and the beneficial effects of boron oxides on the oxygen reduction activity are investigated by first-principles calculations. The single-atom B anchored on the Pt surface has a great attraction for the oxygen species in the immediate environment. With the dissociation of molecular oxygen, a series of boron oxides is formed in succession, both indicating exothermic oxidation reactions. After BO{sub 2} is formed, the subsequent O atom immediately participates in the oxygen reduction reaction. The calculated O adsorption energy is appreciably decreased as compared to Pt catalysts, and more approximate to the optimal value of the volcano plot, from which is clear that O hydrogenation kinetics is improved. The modulation mechanism is mainly based on the electron-deficient nature of stable boron oxides, which normally reduces available electronic states of surface Pt atoms that bind the O by facilitating more electron transfer. This modification strategy from the exterior opens the new way, different from the alloying, to efficient electrocatalyst design for PEMFCs.

    1998-01-01

    The current focus of the CANDU industry is to position the nuclear option as a cost competitive, safe and reliable means of electricity production. To achieve its goal the CANDU industry as a whole is undertaking steps to improve further its performance and safety of its nuclear power plants. A number of programs have been planned and implemented particularly for plants in the mid-life range. Some of these programs include life assessment studies of critical systems, Structures and Components (SSCS), refurbishment and upgrading programs and monitoring and periodic inspection programs. Some elements of the programs have been in place from station start up and some are being instituted as part of the aging management and performance improvement program. The industry recognizes that the key to sustaining high performance over the life of the plant is the implementation of an integrated aging management program that encompasses all elements of plant operation and maintenance. A systematically implemented program on optimized maintenance and inspection strategy, standardized work processes, component rehabilitation programs, and applying lessons learned are some of the elements of a sustainable high performance and an effective plant life assurance program. The paper will describe the elements of an integrated program, the multiphase approach defined for CANDU PLIM and some of the activities undertaken by the industry to further improve and sustain plant safety, reliability and performance.

    2015-04-01

    Full Text Available This article studies the problem of the transmission line conductor heating effect on the active power flows optimization in the local segment of industrial power supply. The purpose is to determine the optimal generation rating of the distributed power sources, in which the power flow values will correspond to the minimum active power losses in the power supply. The timeliness is the need to define the most appropriate rated power values of distributed sources which will be connected to current industrial power supply. Basing on the model of active power flow optimization, authors formulate the description of the nonlinear transportation problem considering the active power losses depending on the transmission line conductor heating. Authors proposed a new approach to the heating model parameters definition based on allowable current loads and nominal parameters of conductors as part of the optimization problem. Analysis of study results showed that, despite the relatively small active power losses reduction to the tune 0,45% due to accounting of the conductors heating effect for the present configuration of power supply, there are significant fluctuations in the required generation rating in nodes of the network to 9,32% within seasonal changes in the outer air temperature. This fact should be taken into account when selecting the optimum power of distributed generation systems, as exemplified by an arbitrary network configuration.

    Full Text Available Mobile devices emerge as the major players to ensure a favorable resource to connect, minimizing the limitation space-time constraints among people and enabling the use of emerging mobile learning (m-learning. The use of mobile devices in pedagogic praxis implies in a closer link between teachers in their initial development and their teacher educator in order to enable the incorporation of this mobile technology in undergraduate courses. This “approach” means the facilitation of meeting to discuss, reflect and talk about the incorporation of this technology in the teaching learning process. In this research, two professors had meetings to discuss and reflect about the employment of this mobile technology in the undergraduate course. One of them, a Chemistry teacher educator and the other is a computer and education teacher-research. The methodological approach is based on a qualitative method with some elements of action-research based on theoretical assumptions of the Activity Theory (ENGESTRÖM, 1999. Therefore, the study based on the debates over the use of mobile devices in the teaching of chemistry was developed as part of the undergraduate course in Chemistry at the Federal University of Rondonia. Among a set of activities, in which students and professors were present with their objects of specific activities, was presented the Activity system related to the construction of those activities. The analysis of SA from the perspective of the 5 principles of Activity Theory points out that the process of collaborative participation in the meetings, the implementation of activities with the students of the degree course and the preparation of scientific papers demonstrated the qualitative evolution of the chemistry teacher educator

  10. The history of the peat manufacturing industry in The Netherlands: Peat moss litter and active carbon

    Directory of Open Access Journals (Sweden)

    2015-11-01

    Full Text Available This article describes the development of three major forms of peat processing by the manufacturing industry in The Netherlands since the last quarter of the 19th century. At a time when peat as a fuel was gradually being replaced by coal, the first form was the peat moss litter industry. Peat moss litter was made from white peat that was ground and sieved in factories which were located mainly in bog areas in the south-east of the province of Drenthe. It served as excellent bedding for horses and cattle. The second form of industrial peat processing was the manufacture, from 1921 onwards, of active carbon made from black peat. The Purit (Norit factory, now part of the Cabot Corporation, is still the only active carbon factory using peat as a raw material. The third form of peat processing was the production of garden peat and potting soil. This is still a widespread activity in peat areas all over the world. The peat moss litter industry thrived from the 1880s until shortly after the First World War. The arrival of the horse-drawn tram in all of the major cities of Europe created a great demand for animal bedding to be used in the vast stables of the tramway companies. Peat moss litter was cleaner, healthier and easier to handle than straw. There was similar demand from the armies, which used millions of horses during the First World War. Owing to the development of motorised vehicles, the peat market collapsed after the war and this plunged the industry into a prolonged crisis which was not overcome until peat was found to be a suitable growing medium for horticulture in the 1950s. Living and working conditions in peatlands were harsh, earnings irregular and labourers’ rights limited. The peat manufacturing industry was the first to introduce collective labour agreements, medical benefits and pension plans. Nonetheless massive unemployment, poverty and the necessity to migrate to other parts of the country were clear signs that the era of

    2017-01-01

    The IT security law forced the energy industry to implement system certifications for the first time in history. In contrast to most companies in the energy industry, which often only knew about product certifications, the energy industry now has to enter new territory. Certification companies receive their legitimation in Germany through DAkkS. The DAkkS is embedded in the context of European Union law. The work of the certification companies is determined by the specifications of the DAkkS as well as by the requirements of the ISO/IEC standards. These regulations should in any case be known to a certification customer so that he knows what a certification company does or does not do. In addition, a certification customer must also know which evidence must be presented in the sense of a reference standard against the certification company. The concrete evidence in this essay is based on an ISO/IEC 27001 certification in conjunction with the IT Security Catalog of the Bundesnetzagentur. With all this knowledge, the cooperation with the certification company will not be a problem for system certification.

    In this study, reduction of estrogenic activity in three different types of effluents from sewage, industrial and livestock wastewater treatment plants by gamma-irradiation was investigated using the yeast two-hybrid assay. After gamma-ray treatment at a dose of 10 kGy, estrogenic activities of sewage, industrial and livestock effluents decreased from 4.4 to 3.0, 1.5 to 1.0 and 16 to 9.9 ng-EEQ L −1 , respectively. The substantial reduction of estrogenic activity in livestock effluent was attributable to the degradation of 17β-estradiol (E2), estrone (E1) and 17α-ethynylestradiol (EE2). Although bisphenol A (BPA) was found at the highest concentration in all effluents, its contribution to the estrogenic activity was not significant due to its low relative estrogenic potency. Meanwhile, the calculated estrogenic activity based on concentrations of E2, E1, EE2 and BPA in the effluents significantly differed from the measured ones. Overestimation may have resulted by dissolved organic matters in effluents inhibiting the estrogenic activity of E2, E1, EE2 and BPA, whereas underestimation was likely due to estrogenic by-products generated by gamma-irradiation. - Highlights: ► Livestock effluent showed strong estrogenic activity due to E2, E1 and EE2. ► EE2 remained in all effluents after gamma-irradiation even at a dose of 10 kGy. ► DOMs in effluents inhibited degradation and activity of estrogenic compounds.

  14. Agrice 2003. Activity report - New industrial resources, from agriculture to bio-products

    International Nuclear Information System (INIS)

    2003-01-01

    Renewable raw materials derived from agricultural crops are used to manufacture bio-products in energy, chemicals and materials industries. Renewable feedstocks address a double need. On the one hand, they offer alternatives to fossil resources, and on the other hand, they are a response to today's environmental challenges: mitigation of the greenhouse affect, reduction of air, soil and water pollution, innocuousness and biodegradability of products. A new chemistry must be created. Large-scale and ongoing research work must be committed to this goal. The research effort implies active coordination of all the various actors involved - multidisciplinary research teams, agro-industrial enterprises, user industries (petrochemicals, chemicals, materials), and specific agricultural branches. With these ends in mind the scientific interest group AGRICE - Agriculture for Chemicals and Energy - was established by public authorities and eight partners in France in 1994. The AGRICE consortium was renewed for six years in 2001, with a broader membership base. AGRICE now includes the following partners: - the research arms of the Commissariat a l'Energie Atomique (CEA), the Institut Francais du Petrole (IFP), and the Institut National de Recherche Agronomique (INRA), - professional organisations representing producers of oilseeds (ONIDOL), grains (AGPB) and beets (CGB), - corporate members ATOFINA, AUTOBAR PACKAGING France, BAYER CROP SCIENCE, CERESTAR France, LIMAGRAIN Agro-Industrie, RHODIA, TOTAL FINA ELF, - the French ministries of Agriculture, Industry, Research, and the Environment, - the French Agency for the Environment and Energy Management (ADEME), - the French Agency for Innovation (ANVAR). ADEME is responsible for managing AGRICE. The consortium is involved in major international undertakings, notably through the European Renewable Resources and Materials Association (ERRMA).

    Madsen, E. L.

    2001-12-01

    Although microorganisms have successfully and spontaneously maintained the biosphere since its inception, industrialized societies now produce undesirable chemical compounds at rates that outpace naturally occurring microbial detoxification processes. This presentation provides an overview of both the complexities of contaminated sites and methodological limitations in environmental microbiology that impede the documentation of biodegradation processes in the field. An essential step toward attaining reliable bioremediation technologies is the development of criteria which prove that microorganisms in contaminated field sites are truly active in metabolizing contaminants of interest. These criteria, which rely upon genetic, biochemical, physiological, and ecological principles and apply to both in situ and ex situ bioremediation strategies include: (i) internal conservative tracers; (ii) added conservative tracers; (iii) added radioactive tracers; (iv) added isotopic tracers; (v) stable isotopic fractionation patterns; (vi) detection of intermediary metabolites; (vii) replicated field plots; (viii) microbial metabolic adaptation; (ix) molecular biological indicators; (x) gradients of coreactants and/or products; (xi) in situ rates of respiration; (xii) mass balances of contaminants, coreactants, and products; and (xiii) computer modeling that incorporates transport and reactive stoichiometries of electron donors and acceptors. The ideal goal is achieving a quantitative understanding of the geochemistry, hydrogeology, and physiology of complex real-world systems.

    Full Text Available This paper seeks to combine traditional methods of measuring intensity with other alternative indicators to examine the dispersion of innovation activities in different industries and countries. The hypothesis that underlies the study lies in the fact that in the Food Processed Industry (IAP the traditional methods are insufficient to detect the core of the innovation process. As method, we analyzed patent data extracted from the twenty-five largest food processed companies in the world and suggested different indicators developed from the Pesquisa de Inovação Tecnológica (PINTEC, 2010 – for Brazilian companies – and the Community Innovation Survey (CIS, 2009 – for European Union companies. The results allowed us to establish relationships in three dimensions: (i the complexity of the innovative effort of the IAP; (ii the efforts to innovation in different countries are distinct and; (iii there is heterogeneity in country performance.

    The new Basic Safety Standards (BSS) for protection against ionizing radiation and for the safety of radiation sources contain nuclide specific exemption levels on reporting. In many cases, these exemption levels differ orders of magnitude, higher or lower, compared to those from the old standards. For the natural radionuclides, the exempted specific activity is much lower (10 or even 1 Bq/g, depending on the radionuclide, compared to 500 Bq/g in the old BSS). As a consequence, industrial activities with certain minerals or raw materials containing elevated concentrations of radionuclides, which were exempted from the radiation protection control system under the old BSS, may have to be declared as radiologically relevant activities and may now come under regulatory control. Examples of these activities are the phosphate ore processing, the refining of a number of metals, the use of slag, and the oil and natural gas production. This might give rise, in some cases, to large volumes of waste which should be treated, conditioned and disposed of in a controlled way. For artificial radionuclides with higher exemption levels, the use of such radionuclides for industrial, medical or research purposes, such as tracers, sealed sources and beta lights, may increase considerably without being controlled any longer by the regulatory system.

    Corn steep liquor (CSL) is a major by-product of the corn steeping process that is utilized in the wet milling industry. To develop new physiologically active polysaccharides from CSL, polysaccharides were isolated and their innate immunostimulatory and anti-metastatic activities were investigated. Corn byproduct polysaccharides (CBP) were preferentially isolated from CSL and further separated into supernatant (CBP1S) and precipitate (CBP1P) fractions. The anti-complementary activity of CBP1S was more potent than CBP1P and CBP. In addition, CBP1S enhanced production of macrophage-stimulating cytokines (e.g., IL-6 and IL-12) and natural killer (NK) cell-activating substances (e.g., granzyme and interferon-γ). Further, CBP1S significantly inhibited lung metastasis at a dose of 1000μg per mouse in an experimental lung metastasis model. These results suggest that CBP1S seems to promote the inhibition of lung metastasis through a mechanism leading to stimulation of the innate immune system, and CBP1S could be used as immunostimulating agents and for industrial applications.

    1997-01-01

    The purpose of this work is to analyze the concept of competitiveness of companies and nations in the upstream sector of the international oil industry, trying to identify the possibilities of future development of this sector as well as the interactions that may exist between different actors such as governments, consumers and oil companies to boost or re-launch the competitive position of their enterprises and countries in the international context of the industry. In order to attain that, we analyze the developments of the most important economic attributes that characterize the oil activity as well as its most crucial political aspects. We develop a model of 'oil competition' and a definition of 'oil competitiveness' that take clearly into consideration both the differences between various oil actors and the dynamic aspects linked to the evolution of the oil industry. We do so by constructing an evolutionist model of competition and competitiveness. This approach emulates a 'biological process' where firms and the economic environment interact with each other within a process similar to 'natural selection' with the survival of the fittest. This evolutionist model adopts some analytical instruments established by Michael Porter, from the University of Harvard, to interpret the changes and the dissimilarities of behavior of various oil actors as well as to explain their respective role in the new oil world that is being organized. Thus, we introduce the notions of 'dominant form of competition' and 'generic strategy of enterprises'. Then, we use our methodology to analyze the past of the oil industry (the stability and the instability). We conclude this work by discussing about the future evolution of the oil activities in the context of a new long term cycle of investment for the sector. (author)

    Full Text Available The goal of our work was to highlight the detoxifying potential of the active principles from lyophilized cilantro and spirulina in experimental contamination with lead, to Carassius gibelio, and their effect on lead antagonism to copper and chromium. 120 Prussian carps, weighing 22-25 g each were divided according to the following treatments for 21 days: C group (without treatment, E1 group (75 ppm Pb into water as Pb(NO32x ½H2O, E2 group (75 ppm Pb into water+2% lyophilized cilantro in feed, E3 group (75 ppm Pb into water+2% lyophilized spirulina in feed. At the end of the experimental period, tissue samples (gills, muscles myotome– epaxial, heart, skin and scales, intestine, liver, brain, gonads, kidney were collected after a starving for 12 hours, and fish euthanasia with clove oil. Determination of Cu and Cr concentration in biological samples was performed using atomic absorption spectrophotometer AAS-VARIAN. Pb addition into water in dose of 75 ppm, has resulted in Cu and Cr mobilization from fish tissues. Decreasing of Cu tissue level occurred less intensive in tissues sampled from groups receiving cilantro and spiriulina powder in feed, maximum efficiency in the counteracting the antagonism against Pb showing spirulina on the heart, liver, and kidney. Cr was maintained at relatively low values, although, cilantro powder has induced in some wise the Pb complexing. In contrast, the freeze-dried spirulina brought the tissue level of Cr close to that of the control group or even has determined its more efficient takeover from the feed.

    Thymoquinone is the major active principle of Nigella sativa (N. sativa) and constitutes about 30% of its volatile oil or ether extract. N. sativa oil and seed are commonly used as a natural remedy for many ailments. Using modern scientific techniques, a number of pharmacological actions of N. sativa have been investigated including immunostimulant, anti-inflammatory, anticancer, antioxidant, antihistaminic, antiasthmatic, hypoglycemic, antimicrobial and antiparasitic. There are only few reports regarding the toxicity of thymoquinone. The present study was carried out to determine LD/sub 50/ of thymoquinone both in mice and rats, orally as well as intraperitoneall, by the method of Miller and Tainter. Autopsy and histopathology of liver, kidney, heart and lungs were also determined. The LD/sub 50/ in mice after intraperitoneal injection was determined to be 104.7 mg/kg (89.7-119.7, 95% confidence interval) and after oral ingestion was 870.9 mg/kg (647.1-1094.8, 95% confidence interval). Whereas, LD/sub 50/ in rats after intraperitoneal injection was determined to be 57.5 mg/kg (45.6-69.4, 95% confidence intervals) and after oral ingestion was 794.3 mg/kg (469.8- 1118.8, 95% confidence intervals). The LD/sub 50/ values presented here after intraperitoneal injection and oral gavages are 10-15 times and 100-150 times greater than doses of thymoquinone reported for its anti-inflammatory, anti-oxidant and anti-cancer effects. Thymoquinone is a relatively safe compound, particularly when given orally to experimental animals. (author)

    Full Text Available Relevance and purpose of the study. Under modern conditions, the share of loss-making enterprises of the coal industry is still high. This brings the solution of the problem of improving the efficiency of their activities up to date. It also determines the purpose of this research. Research methods: scientific generalization, system and factor analysis, and statistical modeling are used in the present work. Results. The article discusses the economic and theoretical aspects of planning the effective activities in the coal industry. The paper analyzes the elasticity of the unit cost price in terms of its labor productivity. It also deals with the elasticity of the volume of output in terms of labor productivity. This indicates that the existing coal mining technologies have, to some extent, exhausted their advantages in the coal industry. They require a change on the achieved level of the capital-labor ratio. It is recommended to strive to ensure advanced ratio of growth of labor productivity of workers compared to the growth rate of unit costs. This should be done at the introduction of a new technology at the enterprises of the coal industry. The advanced ratio of growth in output compared to the growth rate of labor productivity of workers should also be guaranteed. The early growth rate of revenue from sales compared to the growth rate in total costs of production should be provided. The advanced ratio of profit growth compared to the growth rate of revenue from sales has to be provided as well. It is proven that for coal industry enterprises the type of competitive advantages called “the lowest costs” can be the only acceptable one in comparison with other types. We have considered the requirements to the new developed technologies for coal mining. They are as follows: the value of marginal profit in the planned period should be more than the fixed costs of the enterprise; the value of marginal profit in the planned period should be more

    A preliminary study was made to evaluate the use of neutron activation analysis for the characterization of hand-made and industrial explosives for forensic purpose. A total of 26 samples of Chinese firecracker, toy fireworks, sulfur and industrial explosives was analysed non-destructively. Chinese firecracker and toy fireworks showed high degree of homogenity within an individual sample and/or within the samples of the same lot. Antimony was found to be a key element in distinguishing between Chinese firecracker samples. The significant differences in ten element contents (K, Ba, Sr, Na, Br, As, Sb, Sc, La, Sm) were found among toy fireworks samples. The sulfur samples of natural origin and of by-product in refining process of oil were analysed, and the elements such as Se, As and Sb were found to be characteristic of the samples of natural origin. In analysis of industrial explosives, K, Ba and Na were detected as a characteristic element in black powder, smokeless powder of single base and Shiraume dynamite samples, respectively. (author)

    Pectinase has been an integral part of commercial food processing, where it is used for degradation of pectin and facilitates different processing steps such as liquefaction, clarification and juice extraction. The industry currently uses pectinases from mesophilic or thermophilic microorganisms which are well established, but recently, there has been is a new trend in the food industry to adopt low-temperature processing. This trend is due to the potential economic and environmental advantages which the industry envisages. In order to achieve this change, an alternative for the existing pectinases, which are mostly mesophilic and temperature-dependent, must be identified, which can function efficiently at low temperatures. Psychrophilic pectinases derived from cold-adapted microorganisms, are known to function at low to freezing temperatures and may be an alternative to address the problem. Psychrophilic pectinases can be obtained from the vast microflora inhabiting various cold regions on earth such as oceans, Polar Regions, snow-covered mountains, and glaciers. This article is intended to study the advantages of cold active pectinases, its sources, and the current state of the research.

    The aerated bioreactor is a promising technology for wastewater treatment. Activated carbon fiber (ACF) used as a biomembrane carrier in wastewater disposal has attracted much more concern recently. The high modulus polyacrylonitrile (PAN)-based ACF was successfully used as a biomembrane carrier for hard-to-biodegrade industrial organic wastewater disposal in a lab-scale aerated biomembrane reactor at room temperature. The biocompatibility test shows that the biomembrane grows quickly on the ACF filler (ACFF) surface; bacteria and microzoon can breed on the ACFF surface at high chemical oxygen demand (COD) concentration. The COD removal rate tests show that the ACFF bioreactor has high capability to remove COD.

  3. An analysis of the factors influencing demand-side management activity in the electric utility industry

    Bock, Mark Joseph

    Demand-side management (DSM), defined as the "planning, implementation, and monitoring of utility activities designed to encourage consumers to modify their pattern of electricity usage, including the timing and level of electricity demand," is a relatively new concept in the U.S. electric power industry. Nevertheless, in twenty years since it was first introduced, utility expenditures on DSM programs, as well as the number of such programs, have grown rapidly. At first glance, it may seem peculiar that a firm would actively attempt to reduce demand for its primary product. There are two primary explanations as to why a utility might pursue DSM: regulatory mandate, and self-interest. The purpose of this dissertation is to determine the impact these influences have on the amount of DSM undertaken by utilities. This research is important for two reasons. First, it provides insight into whether DSM will continue to exist as competition becomes more prevalent in the industry. Secondly, it is important because no one has taken a comprehensive look at firm-level DSM activity on an industry-wide basis. The primary data set used in this dissertation is the U.S. Department of Energy's Annual Electric Utility Report, Form EIA-861, which represents the most comprehensive data set available for analyzing DSM activity in the U.S. There are four measures of DSM activity in this data set: (1) utility expenditures on DSM programs; (2) energy savings by DSM program participants; and (3) the actual and (4) the potential reductions in peak load resulting from utility DSM measures. Each is used as the dependent variable in an econometric analysis where independent variables include various utility characteristics, regulatory characteristics, and service territory and customer characteristics. In general, the results from the econometric analysis suggest that in 1993, DSM activity was primarily the result of regulatory pressure. All of the evidence suggests that if DSM continues to

    Grape stalk is an organic waste produced in great amounts in the industrialization processes of grape. This work presents the results of studies carried out to use this waste as raw material to prepare activated carbon through the physical and chemical route. The physicochemical characterization of this material suggests the presence of unusually high levels of ashes. Metal content was determined and high levels of potassium, sodium, iron, calcium and magnesium in carbonized and raw grape stalk were exhibited. This characteristic made difficult physical activation at high temperatures. A leaching step was included before the activation with steam, and adsorbents with surface areas between 700 and 900 m(2)/g were obtained. Physical activation was also performed at lower temperatures using carbonized grape stalk without leaching, leading to the development of some grade of porosity, with an area of 412 m(2)/g. These results would indicate the catalytic effect of the minerals present in this raw material. Chemical activation using phosphoric acid as activating agent seemed to be a very efficient method as final products with BET areas between 1000 and 1500 m(2)/g were obtained.

    The halophilic bacterial isolates SS1, SS2, SS3, SS5, and SS8 were characterized for production of industrially important enzymes like amylase, protease, lipase, and glutaminase. Halophilic bacterial isolates SS1 and SS3 exhibited salt dependent extracellular amylase and protease activities. Both the halophilic isolates SS1 and SS3 exhibited maximum amylase and protease activities in the presence of 1.5 and 1.0 M NaCl, respectively, with the optimum pH 8 and temperature 40°C. SS2 showed maximum extracellular protease and lipase activities in the presence of 0.75 M NaCl, at optimum pH of 7, and temperature 37°C. The glutaminase activity of SS3 increased with increase in concentration of NaCl up to 2.5 M. The optimum pH and temperature for L-glutaminase activity of SS3 was 8 and 40°C, respectively. The combined hydrolytic activities of these halophilic bacterial isolates can be used for bioconversion of organic materials to useful products.

  8. Nuclear industry and radioecological safety

    The beginning of XXI century is marked with increasing public concern over impact of man-made activity, including nuclear technologies, on the environment. Currently, the anthropocentric principle is applied in the course of the radioecological safety guaranteeing for the environment, which postulates that human protectability serves as guarantee of the environmental one. However, this principle correctness is called in question recently. The ecocentric principle is proposed as an alternative doctrine, defining balance between human importance and that of any other elements of biota. The system recommended isn't intended for the regulatory standards development yet, because of substantial gaps in scientific knowledge. Nevertheless, renunciation of the anthropocentric principle can result in unwarranted tightened regulatory basis, decreasing of nuclear industry evolution rates, and, consequently, breaching of societal and economical priorities. It is obvious that for the safety guaranteeing, nuclear industry shouldn't stand out against a background of other fields of human activity involved hazard factors. Therefore, new conceptions applying within the regulatory system is to be weighted and exclude formal using of discussion theses. More than semi-centennial experience of the anthropocentric approach applying serves as an evidence of safe protection of ecosystems against radiation exposure that ensures safe ecological development of nuclear power industry and other fields of nuclear technologies application.

    Full Text Available An important issue in Kosovo is water pollution. The use of polluted water has a direct impact on human health and cause long-term consequences. The longest and most polluted river in Kosovo is the Sitnica, a 90 km long river with its source located near the village of Sazli. The river flows into the Ibar River in Northern Kosovo. Agriculture is prevailing activity in the basin of Sitnica which is why agricultural as well as industrial waste are the biggest water pollutants. The purpose of this study was to evaluate water quality of the river and analyse the pollution level along the Sitnica River caused by agricultural activities and industrial discharges. In order to assess the impact of pollutants on this river, a measurements were carried out in four (five monitoring stations: the first station represents the reference station which has not undergone or has not been affected by polluting pressures, two stations in water areas affected by the irrigation of farming land and two monitoring stations in water areas affected by industrial wastewater discharge. Some of the parameters of water quality analysed are temperature, turbidity, electrical conductivity, pH, DO, COD, BOD, P total, nitrates, sulfates, and heavy metals iron, manganese, zinc, nickel. Compared to the reference station the results obtained from the Gracka and Pestova monitoring stations prove that the dominant form of pollution is that from agricultural lands irrigation, while the Plemetin and Mitrovica stations show that the Sitnica River is affected by wastewater discharge which contains significant concentrations of heavy metals, as well as metal ions selected in this paper. It can be concluded that the irrigation of agricultural lands and discharges from mining significantly affect water quality of the Sitnica River.

    The present study focused on inhibitory activity of freshly extracted essential oils from three legal (THChemp varieties (Carmagnola, Fibranova and Futura) on microbial growth. The effect of different sowing times on oil composition and biological activity was also evaluated. Essential oils were distilled and then characterized through the gas chromatography and gas chromatography-mass spectrometry. Thereafter, the oils were compared to standard reagents on a broad range inhibition of microbial growth via minimum inhibitory concentration (MIC) assay. Microbial strains were divided into three groups: i) Gram (+) bacteria, which regard to food-borne pathogens or gastrointestinal bacteria, ii) Gram (-) bacteria and iii) yeasts, both being involved in plant interactions. The results showed that essential oils of industrial hemp can significantly inhibit the microbial growth, to an extent depending on variety and sowing time. It can be concluded that essential oils of industrial hemp, especially those of Futura, may have interesting applications to control spoilage and food-borne pathogens and phytopathogens microorganisms.

    Activated sludge is an artificial ecosystem known to harbor complex microbial communities. Bacterial diversity in activated sludge from pulp and paper industry was studied to bioprospect for laccase, the multicopper oxidase applicable in a large number of industries due to its ability to utilize a wide range of substrates. Bacterial diversity using 454 pyrosequencing and laccase diversity using degenerate primers specific to conserved copper binding domain of laccase like multicopper oxidase (LMCO) genes were investigated. 1231 OTUs out of 11,425 sequence reads for bacterial diversity and 11 OTUs out of 15 reads for LMCO diversity were formed. Phylum Proteobacteria (64.95 %) with genus Thauera (13.65 %) was most abundant followed by phylum Bacteriodetes (11.46 %) that included the dominant genera Paludibacter (1.93 %) and Lacibacter (1.32 %). In case of LMCOs, 40 % sequences showed affiliation with Proteobacteria and 46.6 % with unculturable bacteria, indicating considerable novelty, and 13.3 % with Bacteroidetes. LMCOs belonged to H and J families.

    To explore combinations of worksite supports (WSS) for physical activity (PA) that may assist employees in meeting PA recommendations and to investigate how availability of WSS differs across industries and occupations. Cross-sectional. Several Missouri metropolitan areas. Adults employed >20 h/wk outside the home. Survey utilized existing self-reported measures (eg, presence of WSS for PA) and the International Physical Activity Questionnaire. Logistic regression was conducted for 2 outcome variables: leisure and transportation PA. Independent variables included 16 WSS. Of particular interest were interaction effects between WSS variables. Analyses were stratified by 5 occupation and 7 industry types. Overall, 2013 people completed the survey (46% response rate). Often, availability of 1 WSS did not increase the likelihood of meeting PA recommendations, but several pairs of WSS did. For example, in business occupations, the odds of meeting PA recommendations through transportation PA increased when employees had access to showers and incentives to bike/walk (odds ratio [OR] = 1.6; 95% confidence interval [CI] = 1.16-2.22); showers and maps (OR = 1.25; 1.02-1.55); maps and incentives to bike/walk (OR = 1.48; 1.04-2.12). Various combinations of WSS may increase the likelihood that employees will meet PA recommendations. Many are of low or no cost, including flexible time for exercise and maps of worksite-adjacent walk/bike routes. Findings may be instructive for employers seeking to improve employee health through worksite PA.

    To improve the photocatalytic performance of metal phthalocyanine based catalyst, Copper Phthalocyanine (CuPc) functionalized reduced graphene oxide (RGO) nanocomposite has been synthesized through a simple chemical approach. The obtained product was characterized by X-ray diffraction technique (XRD), Fourier transform infrared (FTIR) spectroscopy, Ultraviolet-visible spectroscopy (UV-vis) and High resolution transmission electron microscopy (HRTEM). The photocatalytic activity of the RGO/CuPc nanocomposite was performed by the degradation of Rhodamine B (RhB) under visible light irradiation. The photocatalytic studies revealed that the RGO/CuPc nanocomposite exhibits much stronger catalytic behavior than the pristine CuPc nanotube. A plausible mechanism for the photodegradation of Rhodamine B (RhB) was suggested. The RGO wrapped CuPc nanotube composite materials offer great potential as active photocatalysts for degradation of organic pollutions in industrial waste water.

    Widespread practices supporting availability of healthful foods, beverages, and physical activity in out-of-school-time (OST) settings would further obesity prevention efforts. The objective of this article was to describe principles to guide policy development in support of healthy eating and physical activity practices in out-of-school settings to promote obesity prevention. The Institute of Medicine's L.E.A.D. framework (Locate Evidence, Evaluate it, Assemble it, and Inform Decisions) was used to identify practices relevant to children's healthful eating in most OST settings: 1) locate and evaluate information from a national survey of children's perceptions of healthful-food access; published research, reports, policies and guidelines; and roundtables with OST organizations' administrators; 2) assemble information to prioritize actionable practices; and 3) inform programmatic direction. Three evidence-informed guiding principles for short-duration OST resulted: 1) drink right: choose water instead of sugar-sweetened beverages; 2) move more: boost movement and physical activity in all programs; and 3) snack smart: fuel up on fruits and vegetables. Healthy Kids Out of School was launched to support the dissemination and implementation of these guiding principles in short-duration OST settings, complementing efforts in other OST settings to shift norms around eating and physical activity.

    Modern humans may have gracile skeletons due to low physical activity levels and mechanical loading. Tests using pre-historic skeletons are limited by the inability to assess behavior directly, while modern industrialized societies possess few socio-ecological features typical of human evolutionary history. Among Tsimane forager-horticulturalists, we test whether greater activity levels and, thus, increased loading earlier in life are associated with greater later-life bone status and diminished age-related bone loss. We used quantitative ultrasonography to assess radial and tibial status among adults aged 20+ years (mean ± SD age = 49 ± 15; 52% female). We conducted systematic behavioral observations to assess earlier-life activity patterns (mean time lag between behavioural observation and ultrasound = 12 years). For a subset of participants, physical activity was again measured later in life, via accelerometry, to determine whether earlier-life time use is associated with later-life activity levels. Anthropometric and demographic data were collected during medical exams. Structural decline with age is reduced for the tibia (female: -0.25 SDs/decade; male: 0.05 SDs/decade) versus radius (female: -0.56 SDs/decade; male: -0.20 SDs/decade), which is expected if greater loading mitigates bone loss. Time allocation to horticulture, but not hunting, positively predicts later-life radial status (β Horticulture  = 0.48, p = 0.01), whereas tibial status is not significantly predicted by subsistence or sedentary leisure participation. Patterns of activity- and age-related change in bone status indicate localized osteogenic responses to loading, and are generally consistent with the logic of bone functional adaptation. Nonmechanical factors related to subsistence lifestyle moderate the association between activity patterns and bone structure. © 2017 Wiley Periodicals, Inc.

    A new material for neutralization of nitrogen oxides is presented. Two or three metals containing catalysts with a good activity and selectivity towards NO x have been obtained. Preparation of carbon catalysts by deposition of the active phase precursor on the initial carbon material prior to activation is considered as the most promising method. An active carbon-based catalyst (AC/Co) has been synthesized Apricot shells preliminary impregnated with a water-alcohol solution of Co nitrate have been used as initial carbon material. after drying they have been subjected to one-phase steam pyrolysis using a fix-bed reactor. The catalyst thus obtained has a specific surface area (BET) of 53 m 2 g -1 , a favorable mesopore volume/total volume ratio (about 0.85) determined by nitrogen adsorption, a suitable mesopore distribution, about 70% of the mesopores being characterized by r p larger than 25 A and a high dispersion of the Co oxide phase. In addition the catalyst possesses the necessary mechanical resistance. The catalyst has exhibited a high activity with respect to NO x reduction with CO at low temperatures (at 150-250 o C which are the temperatures of industrial flue gases, nO conversion up to 60-95% occurs) and a high selectivity. No presence of H 2 O has been established over the whole temperature range (100-300 o C). An additional advantage of the catalyst is the fact that the amount of CO above 150 o C is lower than the stoichiometric which indicates parallel participation in the process of both the active phase and the support (active carbon) It is also important that the presented catalyst has a low price due to the use of waste products from agriculture and the elimination of special thermal treatment of the supported Co nitrate. There are possibilities of using of other organic wastes from agriculture as well as wastes obtained during flotation of coal. (author)

  1. Effect of ozonation on activated sludge from pulp and paper industry.

    Gupta, S; Chakrabarti, S K; Singh, S

    2010-01-01

    Aerobic biological treatment with activated sludge is the predominant process all over the world for treatment of pulp and paper industry wastewater. 50-70% of the biodegradable organic material is oxidized to CO₂ and the rest is converted to bacterial biomass, typically termed as excess sludge or waste activated sludge (WAS). Handling and disposal of WAS in general and in particular from the pulp and paper industry face different processing difficulties, regulatory stringency due to organochlorine contamination and reluctance of people for reuse. With an objective of reducing the net disposable biomass, ozonation of WAS from a pulp and paper mill and from a laboratory scale batch activated sludge process operated with the wastewater and bacterial seed of the same pulp and paper mill have been carried out. With the mill sludge having predominant filamentous organisms 18% MLSS was reduced at an ozone dosage of 55 mg O₃/g dry MLSS solid (DS) resulting in 2.5 times COD increase. With the laboratory sludge which is well structured and flocculating, only 6% MLSS was reduced at an ozone dosage of 55 mg O₃/g DS. Ozonation mineralizes 26% and 20% AOX compounds embedded in the secondary sludge in the mill and laboratory sludge respectively at an ozone dosage of 55 mg O₃/g DS. During ozonation, absorbed/adsorbed lignin on biomass was released which resulted in increased colour concentration. Ozonation can be a potential oxidative pretreatment process for reducing the WAS and paving the way for cost effective overall treatment of WAS.

  2. Chernobyl. Principles of international law in the context of transfrontier environmental pollution as a consequence of a technical-industrial disaster

    The fact that the radioactive cloud released after the MCA in the Chernobyl reactor drifted over 1.300 kilometers in the atmosphere and contaminated the air over Europe, first shown by the alarm in Sweden's nuclear power plant, turned the national Russian disaster into an international case of emergency, a ''matter of international concern'', that creates manifold problems on the level of international law. The author discusses an important aspect, the obligation to inform the other members of the international community about possible transfrontier environmental pollution. The topical case now has shown that the problem of timely, complete, and mutual information in the event of nuclear reactor accidents needs to be systematically regularized by multilateral treaties. The difficulties the Soviet authorities had to master the disaster and its consequences point to problem of whether and to what extent international organisations or states are obliged to, or entitled to, a) offer assistance unasked; b) provide assistance upon request; c) engage in remedial activities against the will of the state concerned. The Chernobyl accident has led to considerations as to extend the concept of 'ultra-hazardous activities' and related legal provisions to also include an obligation to agree upon international information and assistance for disaster control beforehand, on the grounds that such activities may involve inassessible hazards and damage.

    The antioxidant properties of two raw truffles (Terfezia claveryi Chatin and Picoa juniperi Vittadini) and five raw mushrooms (Lepista nuda, Lentinus edodes, Agrocybe cylindracea, Cantharellus lutescens, and Hydnum repandum) were tested by subjecting these truffles and mushrooms to different industrial processes (freezing and canning) and comparing them with common food antioxidants (alpha-tocopherol [E-307], BHA [E-320], BHT [E-321], and propyl gallate [E-310]) with regard to their ability to inhibit lipid oxidation. All of the truffles and mushrooms analyzed exhibited higher percentages of oxidation inhibition than did the food antioxidants according to assays based on lipid peroxidation (LOO*), deoxyribose (OH*), and peroxidase (H2O2). Frozen samples exhibited a small reduction in free radical scavenger activity, but the results did not show a significant difference (P Terfezia, Picoa, and Hydnum showed high or medium antioxidant activity. The Trolox equivalent antioxidant capacity assay was used to provide a ranking order of antioxidant activity as measured against that of Trolox (a standard solution used to evaluate equivalent antioxidant capacity). The order of raw samples with regard to antioxidant capacity was as follows (in decreasing order): Cantharellus, Agrocybe, Lentinus, Terfezia, Picoa, Lepista, and Hydnum. Losses of antioxidant activity were detected in the processed samples of these truffles and mushrooms.

  4. Impacts of Socially Responsible Corporate Activities on Korean Consumers’ Corporate Evaluations in the Agrifood Industry

    Full Text Available The variety of socially responsible corporate activities employed in the agrifood industry has been broadening. An increasing number of agrifood companies have been employing strategic approaches to socially responsible activities, reinforced by Porter and Kramer’s concept of creating shared value (CSV. This study compares the effects on corporate evaluations of two socially responsible corporate activities: philanthropic giving and CSV. Because prior studies concerning the effects of corporate prosocial behaviors on consumer responses have yielded mixed results, the present study examines the effects of a priori perceptions of companies by using corporate stereotypes as moderators. The results show that the type of socially responsible corporate activity (CSV vs. philanthropic giving does not influence corporate evaluations. However, in cases of CSV (vs. philanthropic giving, consumers evaluate an unwarm but competent company more attractively and place higher value on an incompetent but warm company. This research is important not only for enriching existing literature, but also for providing guidelines to practitioners with respect to selecting appropriate corporate initiatives based on perceived consumer stereotypes.

    In this paper the complete set of modified Reynolds´ equations for the active lubrication is presented. The solution of such a set of equations allows the determination of stiffness and damping coefficients of actively lubricated bearings. These coefficients are not just dependent on Sommerfeld n...... in the present paper, i.e. using actively lubricated bearings. By choosing a suitable set of control gains, it is possible not only to increase the stability of the rotor-bearing system, but also enlarge its operational frequency range....... number, as it would be the case of conventional hydrodynamic bearings, but they are also dependent on the excitation frequencies and gains of the control loop. Stiffness as well as damping coefficients can be strongly influenced by the choice of the control strategy, servo valve dynamics and geometry...... of the orifices distributed over the sliding surface. The dynamic coefficients of tilting-pad bearings with and without active lubrication and their influence on an industrial compressor of 391 Kg, which operates with a maximum speed of 10,200 rpm, are analyzed.

    Bioactive compounds and antioxidant activity were evaluated from industrial Jalapeño pepper byproducts and simulated non processed byproducts from two Mexican states (Chihuahua and Sinaloa) to determine their value added potential as commercial food ingredients. Aqueous 80% ethanol produced about 13% of dry extract of polar compounds. Total phenolic content increased and capsaicin and dihydrocapsaicin decreased on scalding samples (80 °C, 2 min) without affecting ascorbic acid. The major phenolic compounds, rutin, epicatechin and catechin comprised 90% of the total compounds detected by HPLC of each Jalapeño pepper byproducts. ORAC analysis showed that the origin and scalding process affected the antioxidant activity which correlated strongly with capsaicin content. Although scalding decreased capsaicinoids (up to 42%), phenolic content by (up to 16%), and the antioxidant activity (variable). Jalapeño pepper byproduct is a good source of compounds with antioxidant activity, and still an attractive ingredient to develop useful innovative products with potential food/non-food applications simultaneously reducing food loss and waste.

    Full Text Available A risk assessment study was conducted to predict the expected hazardous influence on the ecosystem resulted from urbanization and industrialization activities at Helwan area, Egypt. To achieve these goals, soils, plants and water samples were collected from Helwan area, and their total concentrations of inorganic contaminants (Cd, Cr, Co, Cu, Fe, Mn, Ni, Pb, and Zn and organic pollutants; such as Phenol and hydrocarbons were measured. The obtained results showed that, the concentrations of organic contaminants in water streams and surrounding soils recorded high concentration values than the permissible limits, while inorganic elements were within the safe limits for irrigation. In addition, soils irrigated with the effluents of industrial units recorded high values of inorganic and organic contaminants. Consequently, the levels of these contaminants were high in plant tissues grown thereon; especially the edible parts. Risk assessment based on available Predicted No Effect Concentration values for the aquatic and terrestrial environment was performed. Inorganic elements were expected to cause serious hazard problems for both aquatic organisms and soil microorganisms. The impact of these pollutants on human health was calculated using daily metals intake of inorganic metals via consumption of edible plants. Hazard index values proved that concentrations of Cr may cause serious hazard problems for humans in this area; especially, children.

    1977-01-01

    A multifunctional research laboratory, such as Procter and Gamble's Miami Valley Laboratories, requires elemental analyses on many materials. A general survey technique is important even if the information it provides is incomplete or is less precise than single element analyses. Procter and Gamble has developed neutron activation analysis (NAA) capabilities using a nuclear reactor several hundred miles away. The concentration of 40 to 50 elements can be determined in a variety of matrices. We have found NAA to be a powerful supplement to some of the more classical analytical techniques even without having an on-site neutron source. We have also found an automated data acquisition system to be essential for the successful application of NAA in an industrial laboratory

    2003-07-01

    The Galicia industrial activities request a big amount of raw materials energy and water, generating several kinds of residues. Most of them directly spoil the environment, causing important damages. Furthermore, the primary energy self supply capacity doesn't exist at this moment, being substituted by high levels of energetic resources importations satisfying industrial demand without decreasing the electricity and petroleum products exportations. This article tries to develop a complete analysis of this kind of problems, making an approach to the environmental situation of the Galicia manufacturing industry through materials, energy and water flow models. It focuses in those sectors which have a remarkable production within the Galicia industry, analysing their situation in two different years, 1992 and 2000. This will allow to identify possible tendencies of the industry as a whole, like a relative dematerialization, followed by a complete rematerialization.

    Some basic explanations are given of the principles underlying the nuclear fuel cycle, starting with the physics of atomic and nuclear structure and continuing with nuclear energy and reactors, fuel and waste management and finally a discussion of economics and the future. An important aspect of the fuel cycle concerns the possibility of ''closing the back end'' i.e. reprocessing the waste or unused fuel in order to re-use it in reactors of various kinds. The alternative, the ''oncethrough'' cycle, discards the discharged fuel completely. An interim measure involves the prolonged storage of highly radioactive waste fuel. (UK)

    Bixa orellana commonly known as annatto is one of the oldest known natural dye yielding plants native to Central and South America. Various parts of annatto have been widely used in the traditional medical system for prevention and treatment of a wide number of health disorders. The plethora of traditional uses has encouraged researchers to identify and isolate phytochemicals from all parts of this plant. Carotenoids, apocarotenoids, terpenes, terpenoids, sterols, and aliphatic compounds are main compounds found in all parts of this plant and are reported to exhibit a wide range of pharmacological activities. In recent years annatto has received tremendous scientific interest mainly due to the isolation of yellow-orange natural dye from its seeds which exhibits high biodegradability, low toxicity, and compatibility with the environment. Considerable research work has already been done and is currently underway for its applications in food, textile, leather, cosmetic, solar cells, and other industries. The present review provides up-to-date systematic and organized information on the traditional usage, phytochemistry and pharmacology of annatto. It also highlights its non-food industrial applications in order to bring more interest on this dye plant, identifies the existing gaps and provides potential for future studies. Studies reported in this review have demonstrated that annatto holds a great potential for being exploited as source of drugs and a potential natural dye. However, further efforts are required to identify extract biomolecules and their action mechanisms in exhibiting certain biological activities in order to understand the full phytochemical profile and the complex pharmacological effects of this plant.

    Little effort has focused on the role of volunteer-led out-of-school time (OST) programs (ie, enrichment and sports programs) as key environments for the promotion of healthy eating and physical activity habits among school-aged children. The Healthy Kids Out of School (HKOS) initiative developed evidence-based, practical guiding principles for healthy snacks, beverages, and physical activity. The goal of this case study was to describe the methods used to engage regional partners to understand how successful implementation and dissemination of these principles could be accomplished. HKOS partnered with volunteer-led programs from 5 OST organizations in Maine, Massachusetts, and New Hampshire to create a regional "learning laboratory." We engaged partners in phases. In the first phase, we conducted focus groups with local volunteer program leaders; during the second phase, we held roundtable meetings with regional and state program administrators; and in the final phase, we conducted additional outreach to refine and finalize implementation strategies. Implementation strategies were developed based on themes and information that emerged. For enrichment programs, strategies included new patch and pin programs that were consistent with the organizations' infrastructure and usual practices. For sports programs, the main strategy was integration with online trainings for coaches. Through the engagement process, we learned that dissemination of the guiding principles in these large and complex OST organizations was best accomplished by using implementation strategies that were customized, integrated, and aligned with goals and usual practices. The lessons learned can benefit future efforts to prevent obesity in complex environments.

    Self-sustained combustion instabilities are one of the most plaguing challenges and problems in lean-conditioned propulsion and land-based engine systems, such as rocket motors, gas turbines, industrial furnace and boilers, and turbo-jet thrust augmenters. Either passive or active control in open- or closed-loop configurations can be implemented to mitigate such instabilities. One of the classical disadvantages of passive control is that it is only implementable to a designed combustor over a limited frequency range and can not respond to the changes in operating conditions. Compared with passive control approaches, active control, especially in closed-loop configuration is more adaptive and has inherent capacity to be implemented in practice. The key components in closed-loop active control are 1) sensor, 2) controller (optimization algorithm) and 3) dynamic actuator. The present work is to outline the current status, technical challenges and development progress of the active control approaches (in open- or closed-loop configurations). A brief description of feedback control, adaptive control, model-based control and sliding mode control are provided first by introducing a simplified Rijke-type combustion system. The modelled combustion system provides an invaluable platform to evaluate the performance of these feedback controllers and a transient growth controller. The performance of these controllers are compared and discussed. An outline of theoretical, numerical and experimental investigations are then provided to overview the research and development progress made during the last 4 decades. Finally, potential, challenges and issues involved with the design, application and implementation of active combustion control strategies on a practical engine system are highlighted.

    The aim of this study was to evaluate the effect of an industrial exoskeleton on muscle activity, perceived musculoskeletal effort, measured and perceived contact pressure at the trunk, thighs and shoulders, and subjective usability for simple sagittal plane lifting and lowering conditions. Twelve male participants lifted and lowered a box of 7.5 kg and 15 kg, respectively, from mid-shin height to waist height, five times, both with and without the exoskeleton. The device significantly reduced muscle activity of the Erector Spinae (12%-15%) and Biceps Femoris (5%). Ratings of perceived musculoskeletal effort in the trunk region were significantly less with the device (9.5%-11.4%). The measured contact pressure was highest on the trunk (91.7 kPa-93.8 kPa) and least on shoulders (47.6 kPa-51.7 kPa), whereas pressure was perceived highest on the thighs (35-44% of Max LPP). Six of the users rated the device usability as acceptable. The exoskeleton reduced musculoskeletal loading on the lower back and assisted with hip extensor torque during lifting and lowering. Contact pressures fell below the Pain Pressure Threshold. Perceived pressure was not exceptionally high, but sufficiently high to cause discomfort if used for long durations.

    The design of the first polymeric nanoparticles could be traced back to the 1970s, and has thereafter received considerable attention, as evidenced by the significant increase of the number of articles and patents in this area. This review article is an attempt to take advantage of the existing literature on the clinically tested and commercialized biodegradable PLA(G)A-PEG nanotechnology as a model to propose quality building and outline translation and development principles for polymeric nano-medicines. We built such an approach from various building blocks including material design, nano-assembly - i.e. physicochemistry of drug/nano-object association in the pharmaceutical process, and release in relevant biological environment - characterization and identification of the quality attributes related to the biopharmaceutical properties. More specifically, as envisaged in a translational approach, the reported data on PLA(G)A-PEG nanotechnology have been structured into packages to evidence the links between the structure, physicochemical properties, and the in vitro and in vivo performances of the nanoparticles. The integration of these bodies of knowledge to build the CMC (Chemistry Manufacturing and Controls) quality management strategy and finally support the translation to proof of concept in human, and anticipation of the industrialization takes into account the specific requirements and biopharmaceutical features attached to the administration route. From this approach, some gaps are identified for the industrial development of such nanotechnology-based products, and the expected improvements are discussed. The viewpoint provided in this article is expected to shed light on design, translation and pharmaceutical development to realize their full potential for future clinical applications.

    Leaves from the plant species studied herein are traditionally used in northern Nigeria against various protozoan infections. However, none of these herbal preparations have been standardized, nor have their toxicity to mammalian cells been investigated. In search of improved and non-toxic active antiprotozoal principles that are not cross-resistant with current anti-parasitics, we here report the results of the in vitro screening of extracts from seven selected medicinal plant species (Centrosema pubescens, Moringa oleifera, Tridax procumbens, Polyalthia longifolia, Newbouldia laevis, Eucalyptus maculate, Jathropha tanjorensis), used traditionally to treat kinetoplastid infections in Nigeria, and the isolation of their bioactive principles. To investigate the efficacies of medicinal plant extracts, and of compounds isolated therefrom, against kinetoplastid parasites, assess cross-resistance to existing chemotherapy, and assay their toxicity against mammalian cells in vitro. Plants were extracted with hexane, ethyl acetate and methanol. Active principles were isolated by bioassay-led fractionation, testing for trypanocidal activity, and identified using NMR and mass spectrometry. EC 50 values for their activity against wild-type and multi-drug resistant Trypanosoma brucei were obtained using the viability indicator dye resazurin. Seven medicinal plants were evaluated for activity against selected kinetoplastid parasites. The result shows that crude extracts and isolated active compounds from Polyalthia longifolia and Eucalyptus maculata, in particular, display promising activity against drug-sensitive and multi-drug resistant Trypanosoma brucei. The EC 50 value of a clerodane (16α-hydroxy-cleroda-3,13(14)-Z-dien-15,16-olide) isolated from Polyalthia longifolia was as low as 0.38µg/mL, while a triterpenoid (3β,13β-dihydroxy-urs-11-en-28-oic acid) isolated from Eucalyptus maculata displayed an EC 50 of 1.58µg/mL. None of the isolated compounds displayed toxicity

Developed was the mechanism of the economic motivation to make mining operations "environmentally friendly" that includes defrayal of expenses from both direct and indirect damages. 4. Identified were spheres of possible cooperation between mining companies, government organizations, and the NGOs. These include development of standards for Good Neighbor Agreement, exchange of environmental information, international exchange of successful environmental, health, and safety practices. The study showed the necessity for the Russian Federation mining industry to adopt the more successful environmental policies and practices used in developed countries. To achieve this goal the Regional Environmental Management principle, the risk assessment criteria, the mechanism of the economic motivation, and the principles for international cooperation can play an extremely important role.

    Background Non-communicable diseases (NCDs) are the leading cause of mortality in Fiji, a middle-income country in the Pacific. Some food products processed sold and marketed by the food industry are major contributors to the NCD epidemic, and the food industry is widely identified as having strong economic and political power. However, little research has been undertaken on the attempts by the food industry to influence public health-related policies and programs in its favour. The ?corporat...

    Basic principles of a novel method of cancer treatment are explained. Method is based on the thermal activation of an inactive prodrug encapsulated in magnetoliposomes via Neél and Brown effects of inductive heating of subdomain superparamagnetic particles to sufficiently high temperatures. This principle may be combined with targeted drug delivery (using constant magnetic field) and controlled release (using high-frequency magnetic field) of an activated drug entrapped in magnetoliposomes. Using this method drug may be applied very selectively in the particular site of organism and this procedure may be repeated several times using e.g. stealth magnetoliposomes which are circulating in a blood-stream for several days. Moreover the magnetoliposomes concentrated by external constant magnetic field in tumor vasculature may lead to embolic lesions and necrosis of a tumor body and further the heat produced for thermal activation of a drug enhances the effect of chemotherapy by local hyperthermic treatment of neoplastic cells.

    2015-06-01

    Full Text Available The article presents the results of a study which aims to determine the effect of the number of industrial vertical linkages and participation in the supply chain on innovation activity of food industry in western Poland. The main research hypothesis is the assumption that innovation processes in food industry are strongly determined by the intensity and nature of the linkages and membership in the supply chain. The scope of the survey relates to innovation in food industry, concerns innovation at the company level and takes into account the diffusion to the “new to the company”. Innovative activities are divided into three general groups including: expenditure on research and development and investments in fi xed assets not used so far (such as: buildings, premises and land, machinery and equipment, computer software, implementation of new products and processes, and innovative collaboration. The survey covers 422 industrial enterprises. The methodological part of the study uses probit modelling that enables to identify the probability of occurrence of innovation activity.

    Full Text Available Purpose: the main goal of the publication is to make a comprehensive study of the possible application of the cluster approach to improve the competitiveness and innovation activity of enterprises of the defense industry complex.Methods: the methodology of the research is based on the collection and analysis of initial data and information, the article uses a systematic approach to the study of socio-economic processes and phenomena. The research is based on modern theory of competition, innovation, as well as the modern paradigm of cluster development of the economy. In preparing the study, practical materials from Corporation “Rostec”.Results: the article gives the notion of cluster, the prospects for the use of the cluster approach to enhance competitiveness and innovation enterprises of the military-industrial complex. It is noted that the activation of interaction with the “civil sector” is particularly relevant in the context of the reduction of the state defense order, and the theory and practice of cluster management offers a number of forms of cluster interaction between the enterprises of the defense industry and the civil sector. It is emphasized that the development of cluster mechanisms can solve a number of problems related to the insufficient financial stability of defense industry enterprises in the context of a reduction in the state defense order, low innovation activity and the lack of developed models of interaction with small innovative enterprises. Ultimately, the use of cluster mechanisms in the development of defense enterprises is intended to enhance the competitiveness of the complex, both nationally and globally. It is stated that the existing clusters are not able to fully solve a number of specific tasks related to the diversification of integrated defense industry structures. Attention is drawn to the fact that existing clusters are not able to fully solve a number of specific tasks related to the

  12. How is post-industrial decline associated with the geography of physical activity? Evidence from the Health Survey for England.

    Rind, Esther; Jones, Andy; Southall, Humphrey

    2014-03-01

    In recent decades, the prevalence of physical activity has declined considerably in many developed countries, which has been related to rising levels of obesity and several weight-related medical conditions, such as coronary heart disease. There is evidence that areas exhibiting particularly low levels of physical activity have undergone a strong transition away from employment in physically demanding occupations. It is proposed that such processes of deindustrialisation may be causally linked to unexplained geographical disparities in physical activity. This study investigates how geographical variations in deindustrialisation are associated with current levels of physical activity across different activity domains and relevant macro-economic time periods in England. The analysis includes data on 27,414 adults from the Health Survey for England 2006 and 2008 who reported total, occupational, domestic, recreational and walking activity. Based on employment change in industries associated with heavy manual work, a local measurement of industrial decline was developed, covering the period 1841-2001. We applied a multilevel modelling approach to study associations between industrial decline and physical activity. Results indicate that the process of deindustrialisation appears to be associated with patterns of physical activity and that this is independent of household income. The effects observed were generally similar for men and women. However, the nature of the association differed across areas, time periods and employment types; in particular, residents of districts characterised by a history of manufacturing and mining employment had increased odds of reporting low activity levels. We conclude that post-industrial change may be a factor in explaining present-day variations in physical activity, emphasising the plausible impact of inherited cultures and regional identities on health related behaviours.

    2011-01-01

    This work presents a summary of the IAEA Safety Standards Series publication No. SF-1 entitled F UDAMENTAL Safety PRINCIPLES p ublished on 2006. This publication states the fundamental safety objective and ten associated safety principles, and briefly describes their intent and purposes. Safety measures and security measures have in common the aim of protecting human life and health and the environment. These safety principles are: 1) Responsibility for safety, 2) Role of the government, 3) Leadership and management for safety, 4) Justification of facilities and activities, 5) Optimization of protection, 6) Limitation of risks to individuals, 7) Protection of present and future generations, 8) Prevention of accidents, 9)Emergency preparedness and response and 10) Protective action to reduce existing or unregulated radiation risks. The safety principles concern the security of facilities and activities to the extent that they apply to measures that contribute to both safety and security. Safety measures and security measures must be designed and implemented in an integrated manner so that security measures do not compromise safety and safety measures do not compromise security.

    The design and dimensioning of nuclear power plant structures necessitate the evaluation of risks due to industrial activity. Among these risks, those due to the storage or transport of dangerous products merit special attention. They result, inter alia, in the explosion of flammable gas clouds. Such clouds can drift before igniting and, once alight, the resulting pressure wave can cause serious damage, even at a distance. A methodology both deterministic and probabilistic enabling this risk to be quantified has therefore been developed. It is based in part on an analysis of the statistics of actual accidents that have occurred. After briefly recalling the probabilistic model, the typical accidents selected are described and for three usual cases (storage under pressure, rail tank cars and road units) the main characteristics of the rupture are explicited. The deterministic models that have been worked out to calculate the consequences of such an accident: flow rate at the bursting point, evaporation, drift and atmospheric dispersion of the cloud formed, explosion of this cloud, are then described. At the present time the overpressure wave is quantified against a TNT equivalent of the explosive mixture. Some data are given as examples for three commonly employed hydrocarbons (butane, propane, propylene) [fr

    Full Text Available Sago industries effluent containing large amounts of organic content produced excess sludge which is a serious problem in wastewater treatment. In this study ozonation has been employed for the reduction of excess sludge production in activated sludge process. Central composite design is used to study the effect of ozone treatment for the reduction of excess sludge production in sago effluent and to optimise the variables such as pH, ozonation time, and retention time. ANOVA showed that the coefficient determination value (R2 of VSS and COD reduction were 0.9689 and 0.8838, respectively. VSS reduction (81% was achieved at acidic pH 6.9, 12 minutes ozonation, and retention time of 10 days. COD reduction (87% was achieved at acidic pH 6.7, 8 minutes of ozonation time, and retention time of 6 days. Low ozonation time and high retention time influence maximum sludge reduction, whereas low ozonation time with low retention time was effective for COD reduction.

    Full Text Available The article off ers the analysis of expenditures on technological innovation in Russia and abroad. The author outlines the main reasons of the low level of technological development of Russian industrial companies. A number of organizational and economic measures to create conditions for technological development of the Russian economy are considered. In recent years, there was an essential increase in output of innovative products, works and services that coincided with the increased ratio of volumes of technological innovations to their costs. However, the expected decrease of this ratio in the coming years may cause slower growth of volumes of innovative production that requires drastic measures, especially aimed at restricting key factors impeding innovative activities. These factors include lack of own funds, high cost of innovations, lack of fi nancial support from the state, high economic risk and low innovative potential of the organization.

    2010-01-01

    The decolorization of industrial wastewater containing direct dye (Drimarene Red CL-3B) by advanced oxidation process using ozonation in a semi-batch bubble column reactor followed by granule activated carbon (GAC) adsorption process was studied. The effect of initial dye concentration, ozone concentration, pH and ozone-air flow rate on the rate of dye decolorization were investigated. It was found that the rate of dye decolorization increases with increasing ozone concentration, ozone-air flow rate, and pH but decreases with increasing initial dye concentration. This study is a hybrid system conducted in combination between ozonation process and GAC adsorption to reveal higher and efficient removal of color and TOC. The process started with ozonation for efficient and rapid decolorization of dyeing wastewater, followed by GAC adsorption process to gain efficient removal of color and TOC. The adsorption process was found to be very efficient in removal of ozonation residual TOC, in view of high TOC removal, up to 37% TOC removal was obtained. Numerical correlation using regression analysis for decolorization time with the operating conditions of the ozonation process were presented.

    Full Text Available Cytoplasmic pyruvate decarboxylase (PDC, EC 4.1.1.1 is one of the key enzymes of yeast fermentative metabolism. PDC is the first enzyme which, under anaerobic conditions, leads to decarboxylation of pyruvate with acetaldehyde as the end product. The aim of this study is to develop a suitable method for PDC activity assay in situ for different industrial yeast strains. Saccharomyces sp. and Debaryomyces sp. yeast strains grew in fermentative medium with 12 % of glucose. Enzymatic assay was conducted in cell suspension treated with digitonin as permeabilisation agent, and with sodium pyruvate as a substrate, at temperature of 30 °C. Metabolites of PDC pathway were detected using gas chromatographic (GC technique. Various parameters like type and molar concentration of the substrate, minimal effective mass fraction of digitonin, cell concentration, reaction time and effect of pyrazole (alcohol dehydrogenase inhibitor were monitored to optimize PDC enzymatic assay in situ. In the concentration range of yeast cells from 1⋅10^7 to 1⋅10^8 per mL, linear correlation between the produced acetaldehyde and cell density was noticed. Only pyruvate was the specific substrate for pyruvate decarboxylase. In the presence of 0.05 M sodium pyruvate and 0.05 % digitonin, the enzymatic reaction was linear up to 20 min of the assay. During incubation, there was no formation of ethanol and, therefore, pyrazole was not necessary for the assay.

    Background Little effort has focused on the role of volunteer-led out-of-school time (OST) programs (ie, enrichment and sports programs) as key environments for the promotion of healthy eating and physical activity habits among school-aged children. The Healthy Kids Out of School (HKOS) initiative developed evidence-based, practical guiding principles for healthy snacks, beverages, and physical activity. The goal of this case study was to describe the methods used to engage regional partners to understand how successful implementation and dissemination of these principles could be accomplished. Community Context HKOS partnered with volunteer-led programs from 5 OST organizations in Maine, Massachusetts, and New Hampshire to create a regional “learning laboratory.” Methods We engaged partners in phases. In the first phase, we conducted focus groups with local volunteer program leaders; during the second phase, we held roundtable meetings with regional and state program administrators; and in the final phase, we conducted additional outreach to refine and finalize implementation strategies. Outcomes Implementation strategies were developed based on themes and information that emerged. For enrichment programs, strategies included new patch and pin programs that were consistent with the organizations’ infrastructure and usual practices. For sports programs, the main strategy was integration with online trainings for coaches. Interpretation Through the engagement process, we learned that dissemination of the guiding principles in these large and complex OST organizations was best accomplished by using implementation strategies that were customized, integrated, and aligned with goals and usual practices. The lessons learned can benefit future efforts to prevent obesity in complex environments. PMID:26704443

    The economic burden of inactivity is substantial, with conservative estimates suggesting the global cost to health care systems is more than US$50 billion. School-based programs, including physical education and school sport, have been recommended as important components of a multi-sector, multi-system approach to address physical inactivity. Additionally, community sporting clubs and after-school programs (ASPs) offer further opportunities for young people to be physically active outside of school. Despite demonstrating promise, current evidence suggests school-based physical activity programs, community sporting clubs and ASPs are not achieving their full potential. For example, physical activity levels in physical education (PE) and ASP sessions are typically much lower than recommended. For these sessions to have the strongest effects on young people's physical activity levels and their on-going physical literacy, they need to improve in quality and should be highly active and engaging. This paper presents the Supportive, Active, Autonomous, Fair, Enjoyable (SAAFE) principles, which represent an evidence-based framework designed to guide the planning, delivery and evaluation of organized physical activity sessions in school, community sport and ASPs. In this paper we provide a narrative and integrative review of the conceptual and empirical bases that underpin this framework and highlight implications for knowledge translation and application.

    The present study was designed to compare the potential of turmeric and its active principle curcumin on T(3)-induced oxidative stress and hyperplasia. Adult male Wistar strain rats were rendered hyperthyroid by T(3) treatment (10 μg · 100 g(-1) · day(-1) intraperitoneal for 15 days in 0.1 mM NaOH) to induce renal hyperplasia. Another two groups were treated similarly with T(3) along with either turmeric or curcumin (30 mg kg(-1) body weight day(-1) orally for 15 days). The results indicate that T(3) induces both hypertrophy and hyperplasia in rat kidney as evidenced by increase in cell number per unit area, increased protein content, tubular dilation and interstitial edema. These changes were accompanied by increased mitochondrial lipid peroxidation and superoxide dismutase activity without any change in catalase activity and glutathione content suggesting an oxidative predominance. Both turmeric and curcumin were able to restore the level of mitochondrial lipid peroxidation and superoxide dismutase activity in the present dose schedule. T(3)-induced histo-pathological changes were restored with turmeric treatment whereas curcumin administration caused hypoplasia. This may be due to lower concentration of curcumin in the whole turmeric. Thus it is hypothesized that regulation of cell cycle in rat kidney by T(3) is via reactive oxygen species and curcumin reveres the changes by scavenging them. Although the response trends are comparable for both turmeric and curcumin, the magnitude of alteration is more in the later. Turmeric in the current dose schedule is a safer bet than curcumin in normalizing the T(3)-induced hyperplasia may be due to the lower concentration of the active principle in the whole spice.

    The objective of the present work was to establish the antioxidative ability linked to lipophilic, hydrophilic, and polyphenolic fractions of new tomato hybrids of industrial interest, grown in an outdoor field, named "Medugno", situated in the Agro-Nocerino Sarnese area (Province of Salerno, Campania Region, Italy). Antioxidant activities of lipophilic, hydrophilic, and polyphenolic extracts of tomato hybrids determined by the 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid), N,N-dimethyl-p-phenylenediamine dihydrochloride, and 2,2-diphenyl-1-picrylhydrazyl methods, respectively, showed the best results in hybrids obtained between the pure San Marzano and Black Tomato lines. Antioxidant activity tests, performed also on the San Marzano × Black Tomato hybrid (pulped tomatoes), indicated that the industrial transformation process of this new tomato hybrid did not cause a significant loss of antioxidant activity. The in vitro production of nitrite by lipopolysaccharide-stimulated macrophages J774A.1 performed on lipophilic extracts showed that only two hybrids (San Marzano × Black Tomato and Marmande × Black Tomato) inhibited, in a concentration-related manner, nitric oxide release. Results suggested that genotypic factors could determine the nutritional quality of tomato because of the content of biologically active compounds and their biosynthesis. Moreover, the new tomato hybrid achieved could have a potential for the agri-food industry because of its nutritional quality and because it lends itself in processes of industrial transformation.

    The traditional industrial operations are well recognized as an important source of heavy metal pollution, while that caused by the e-waste recycling activities, which have sprouted in some developing countries, is often overlooked. This study was carried out to compare the status of soil heavy metal pollution caused by the traditional industrial operations and the e-waste recycling activities in the Pearl River Delta, and assess whether greater attention should be paid to control the pollution arising from e-waste recycling activities. Both the total contents and the chemical fractionation of major heavy metals (As, Cr, Cd, Ni, Pb, Cu, and Zn) in 50 surface soil samples collected from the e-waste recycling areas and 20 soil samples from the traditional industrial zones were determined. The results show that the soils in the e-waste recycling areas were mainly polluted by Cu, Zn, As, and Cd, while Cu, Zn, As, Cd, and Pb were the major heavy metals in the soils from the traditional industrial zones. Statistical analyses consistently show that Cu, Cd, Pb, and Zn in the surface soils from both types of sites were contributed mostly by human activities, while As, Cr, and Ni in the soils were dominated by natural background. No clear distinction was found on the pollution characteristic of heavy metals in the surface soils between the e-waste recycling areas and traditional industrial zones. The potential ecological risk posed by heavy metals in the surface soils from both types of sites, which was dominated by that from Cd, ranged from low to moderate. Given the much shorter development history of e-waste recycling and its largely unregulated nature, significant efforts should be made to crack down on illegal e-waste recycling and strengthen pollution control for related activities.

  11. Eye lens dose monitoring in the UK nuclear industry using active personal dosemeters.

    Science.gov (United States)

    McWhan, Andrew Forrest; Dobrzynska, Wioletta

    2017-11-20

    The reduction of the dose limit for eye lens from 150 to 20 mSv year-1 must be implemented by EU member states by February 2018. Consequently, there is a requirement for all employers engaged with work with ionising radiation to have appropriate monitoring arrangements in place by this date to demonstrate that they can meet this new limit for all workers. Eye lens dose is conventionally monitored by specific dosemeters worn near the eye. However, it is usually impractical for these dosemeters to be worn at all times in the workplace which can lead to problems accounting for any periods of work when an eye lens dosemeter has not been worn. The Berkeley Approved Dosimetry Service provides a monitoring service for 22 nuclear sites in the UK using active personal dosemeters (APDs) for measuring Hp(10) and Hp(0.07). TLDs for extremity and eye are also issued as appropriate for the working conditions. An analysis of the data from 2007 to 2016 concludes that the values for Hp(0.07) as monitored indirectly by APDs worn on the trunk are comparable to the values assessed by specific Hp(3) eye TLDs. This paper sets out evidence that compliance with the 20 mSv dose limit for the eye lens can be demonstrated using routine issue APDs although specific eye TLDs may still be required to meet international guidance for non-uniform workplace fields. This evidence supports the recent statement from IRPA that "for the nuclear industry and other non-medical sectors the use of a whole body dosimeter is considered likely to be sufficient for the majority of workers". © 2017 IOP Publishing Ltd.

    2017-01-01

    The aims were to: (1) identify, monitor and analyse the Corporate Social Responsibility (CSR) practices of the alcohol industry in Latin America and the Caribbean (LAC) and (2) examine whether the alcohol industry is using these actions to market their products and brands. Nine health experts from Argentina, Brazil and Uruguay conducted a content analysis of 218 CSR activities using a standardized protocol. A content rating procedure was used to evaluate the marketing potential of CSR activities as well as their probable population reach and effectiveness. The LEAD procedure (longitudinal, expert and all data) was applied to verify the accuracy of industry-reported descriptions.

    Environmental damage has reached catastrophic proportions, implying the death of hundreds of people or expenses of many hundreds of million dollars. The financial impact of this damage is however small at the level of the industrial sector concerned which could bear its costs. If States would take measures to redistribute such costs, they would avoid having to compensate victims of the gravest accidents. Special procedures were introduced for this purpose in certain industrial sectors. (NEA) [fr

    Ghribi, Manel; Meddeb-Mouelhi, Fatma; Beauregard, Marc

    2016-01-01

    This study is the first comprehensive investigation of enzyme-producing bacteria isolated from four sludge samples (primary, secondary, press and machine) collected in a Kraft paper mill. Overall, 41 strains encompassing 11 different genera were identified by 16S rRNA gene analysis and biochemical testing. Both biodiversity and enzymatic activities were correlated with sludge composition. Press sludge hosted the largest variety of bacterial strains and enzymatic activities, which included hydrolytic enzymes and ligninolytic enzymes. In contrast, strains isolated from secondary sludge were devoid of several enzymatic activities. Most strains were found to metabolize Kraft liquor at its alkaline pH and to decolorize industrial lignin-mimicking dyes. Resistance to lignin or the ability to metabolize this substrate is a prerequisite to survival in any paper mill sludge type. We demonstrate here that the bacterial strains found in a typical Kraft paper mill represent a source of potential novel enzymes for both industrial applications and bioremediation.

  1. Using non-local databases for the environmental assessment of industrial activities: The case of Latin America

    International Nuclear Information System (INIS)

    Osses de Eicker, Margarita; Hischier, Roland; Hurni, Hans; Zah, Rainer

    2010-01-01

    Nine non-local databases were evaluated with respect to their suitability for the environmental assessment of industrial activities in Latin America. Three assessment methods were considered, namely Life Cycle Assessment (LCA), Environmental Impact Assessment (EIA) and air emission inventories. The analysis focused on data availability in the databases and the applicability of their international data to Latin American industry. The study showed that the European EMEP/EEA Guidebook and the U.S. EPA AP-42 database are the most suitable ones for air emission inventories, whereas the LCI database Ecoinvent is the most suitable one for LCA and EIA. Due to the data coverage in the databases, air emission inventories are easier to develop than LCA or EIA, which require more comprehensive information. One strategy to overcome the limitations of non-local databases for Latin American industry is the combination of validated data from international databases with newly developed local datasets.

    pattern in religion and its age-old principles on body movement as a matter subject to moral discussion. With the new society arising from the Industrial Revolution a new concept of the body is created as an educational object for its labour aim. Firstly, gymnastics comes up as a tool for collective instruction in the new discipline of ruled movement of the body. Afterwards, it was English sports, based on team strategies and rule-based play that become established. In both cases, gymnastics and sport derive from a new core of values in which competition, joint effort and sense of surmounting are the dominant references. Such values are, likewise, connected to the nationalist spirit emerging in the 19th century. Thus, the birth of nation-states in Europe runs parallel to industrial economy and to a new body conception which evolves from gymnastics to sport. In this article we analyze the case of modernization of Spain, showing some illustrative examples of the change in the values concerned with physical activity carried out during the passage from the 19th to the 20th century.

    The implications of the weak equivalence principles are investigated in detail for electromagnetic systems in a general framework. In particular, it is shown that the universality of free-fall trajectories (Galileo weak equivalence principle) does not imply the validity of the Einstein equivalence principle. However, the Galileo principle plus the universality of free-fall rotation states does imply the Einstein principle.

It is found that the dissociation of O{sub 2} on the YSZ(111) surface is largely enhanced by the supported Ni dimer, which is predicted to be the smallest Ni cluster needed for efficient O{sub 2} dissociation. The results would provide an important reference to improve the activity and efficiency of the Ni/YSZ(111) nanocomposite catalysts in cost-effective materials.

    2016-07-21

    Using first-principles density functional theory (DFT) calculations, we demonstrate that catalytic activities toward oxygen reduction and evolution reactions (ORR and OER) in a Li-O2 battery can be substantially improved with graphene-based materials. We accomplish the goal by calculating free energy diagrams for the redox reactions of oxygen to identify a rate-determining step controlling the overpotentials. We unveil that the catalytic performance is well described by the adsorption energies of the intermediates LiO2 and Li2O2 and propose that graphene-based materials can be substantially optimized through either by N doping or encapsulating Cu(111) single crystals. Furthermore, our systematic approach with DFT calculations applied to design of optimum catalysts enables screening of promising candidates for the oxygen electrochemistry leading to considerable improvement of efficiency of a range of renewable energy devices.

  14. Employment within the power supply industry and the power supply related activities; Sysselsatte i kraftnaeringen og kraftrelatert virksomhet 2011

    2012-07-01

    The report's main objective is to investigate employment within the power supply industry and the power supply related activities. The report will describe the composition of employees in regard to sex, age and education. The power supply industry is defined in Statistics Norway's Standard Industrial Classification, as 'Production and distribution of electricity'. The group of companies related to power supply related activities employ similar persons in regard to education and occupation, typical to companies in the power supply industry. These two groups make up the power supply sector in this report. In 2011 there were 18 450 employees in the power supply sector. This constitutes an increase of nearly 13.5 per cent since 2004 and 1.1 per cent since 2010. The sex distribution of about 80 per cent men and 20 per cent women has been fairly stable since 2004. The power supply sector has a low share of women among its employees compared to the private sector in general. In 2011 the level of education in the power supply sector was higher than for the private sector in general. Since 2004, the share of persons with higher education has increased from 27 to 33 per cent. Employees in the power supply sector are on average older than employees in the private sector. The employees have matured since 2004, but in the last few years, there have also been signs of fresh recruitment. The power supply industry had a net influx of 380 new employees, in the period between 2009 and 2011. There were 1678 new employees and 1298 employees lost in the sector due to attrition. If we look at the supply of new employees who were also employed in 2010, 14.2 percent of female employees worked in temporary staff recruitment agencies. Temporary work seems to be an important entry gate to the power supply industry for women. Among men, the building- and construction sector was the most common background for new employees in the power supply industry. Among people who quit

    Full Text Available O diabetes melito é considerada como uma síndrome que é, quanto a etiologia e patogênese, caracterizada por alterar a homeostase do organismo, por distúrbios metabólicos complexos e primários dos carboidratos, que envolvem secundariamente, porém de forma importante, lipídeos e proteínas. Grande número de espécies de plantas tem sido usado experimentalmente para tratar os sintomas do diabetes melito e a distância filogenética entre este grupo de plantas é forte indicação da natureza variada de seus constituintes. Tem sido constatado que muitas substâncias extraídas de plantas reduzem o nível de glicose no sangue. A grande diversidade de classes químicas indica que uma variedade de mecanismos de ação deve estar envolvida na redução do nível de glicose no sangue. Algumas destas substâncias podem ter potencial terapêutico enquanto outras podem produzir hipoglicemia como um efeito colateral devido à sua toxicidade, especialmente hepatotoxidade. Este artigo apresenta uma revisão atualizada e acrescenta mais plantas e princípios ativos hipoglicemiantes à extensa lista existente nos artigos de revisão anteriores.Diabetes mellitus comprises a group of ethiologically and clinically heterogeneous disorders with a common set of symptoms: excessive thirst and hunger, muscular weakness, weight loss, excessive urination and elevation of the blood glucose level among others. There has been a striking emergence of non-insulin-dependent diabetes mellitus as a major health problem in populations undergoing modernization of life-style, both in developed and underdeveloped nations. Many species of plants have been used ethnopharmacologically or experimentally to treat symptons of diabetes mellitus. The high percentage of active plants probably reflects, at least in part, the great variety of possible active constituents and mechanisms of action. The wide diversity of chemical classes indicate a variety of mechanisms must be involved

  17. Comparison between worker-deaths in modern industries and in nuclear activities

    International Nuclear Information System (INIS)

    Failla, L.

    1977-01-01

    The author examines the statistical data related to the deaths of workers in modern industries. This analysis regards deaths by accident. It regards some particular countries in the world; these particular countries have been selected because their data are comparable. The analysis in modern industry regards different years (1965 - 1974). For the worker deaths caused by professional diseases, some particular considerations are made in this paper. Due to the fact that international statistics for worker deaths due to professional diseases don't exist, it was necessary to resort to the existing correllation between professional diseases and accidents in industry, to extrapolate, with some approximation, the number of deaths due to professional disease. Using these considerations it is possible to find some interesting data. Then the author examines the statistics in order to compare them with those pertinent to nuclear energy. With regard to this topic, the author considers the mortal-risks from radiation exposures. Then the author compares the philosophy that is used in modern industry and in the nuclear energy field. A special discussion is carried on about ICRP conception, expressed in Publication 22; ''Implications of Commission Recommendations that Doses be kept as Low as Readily Achievable''

    Although numerous studies have addressed the influence of exogenous pollutants on microorganisms, the effect of long-term industrial waste effluent (IWE) pollution on the activity and diversity of soil bacteria was still unclear. Three soil samples characterized as uncontaminated (R1), moderately contaminated (R2), and highly contaminated (R3) receiving mixed organic and heavy metal pollutants for more than 20 years through IWE were collected along the Mahi River basin, Gujarat, western India. Basal soil respiration and in situ enzyme activities indicated an apparent deleterious effect of IWE on microbial activity and soil function. Community composition profiling of soil bacteria using 16S rRNA gene amplification and denaturing gradient gel electrophoresis (DGGE) method indicated an apparent bacterial community shift in the IWE-affected soils. Cloning and sequencing of DGGE bands revealed that the dominated bacterial phyla in polluted soil were affiliated with Firmicutes, Acidobacteria, and Actinobacteria, indicating that these bacterial phyla may have a high tolerance to pollutants. We suggested that specific bacterial phyla along with soil enzyme activities could be used as relevant biological indicators for long-term pollution assessment on soil quality.

  6. Useful Principles in Plant Excellence Promotion

    International Nuclear Information System (INIS)

    Kavsek, D.; Bozin, B.

    2002-01-01

    This presentation offers a discussion of some principles identified from a review of significant industry events that affected the safety or reliability of a large number of nuclear power plants worldwide. Over the years of operation, a number of events have occurred in nuclear power plants that have involved problems in human performance. A review of these and other significant events has identified recurring weaknesses in plant safety culture and policy and procedure weaknesses. Focusing attention on strengthening relevant processes can help plants avoid similar significant events. Events continue to occur because the lessons learned from industry and plant operating experience are ineffectively used. In some cases, industry events have been communicated to the personnel of the plant in question, but without a thorough explanation of the lessons learned and applicability to the plant. The corrective actions identified have sometimes been limited in scope and have not fully addressed generic issues. The review and implementation of corrective actions for in-house events have sometimes been inadequate to prevent recurrences. An effective operating experience program can significantly reduce the potential for recurring events. The value of learning and applying the knowledge gained from operating experience should be an integral part of plant culture and promoted as an expectation. When operating experience is reviewed, generic issues and causal factors should be explored, rather than focusing on the unique problems that led to a specific event. Lessons learned and applicability to the plant must be clearly identified, corrective action taken, and changes thoroughly communicated to the plant personnel. Their understanding of the changes and the reasons for them should then be confirmed. The following principles will be discussed in this presentation: recognizing conditions during evolutions, promoting teamwork, recognizing fundamental knowledge weaknesses

    The transformation that has taken place in Canada's natural gas industry since the 1985 deregulation was reviewed. The 1985 'Halloween Agreement' was pivotal in deregulating the wholesale gas commodity business and paved the way for a truly competitive market for natural gas in Canada. Results of deregulation have been significantly lower prices for natural gas and a tripling of the natural gas market in Canada. Currently, natural gas represents 31 per cent of total energy consumption in Canada and approximately 22 per cent in the United States. New suppliers and industry players have entered the market to widen the choice and competition of energy products and services. Apart from the competition that resulted from deregulation, the convergence of the gas and electricity industries was considered to have been the most significant development. Ramifications of the gas-electricity convergence were reviewed. While the final outcome of the convergence in terms of the number and size of the companies operating in the market will not be known for some time, the de facto globalization of the natural gas business by reason of its interplay and offplay in regional markets with other forms of energy, is a well known fact. Further convergence, such as oil/natural gas/electricity was predicted

    Extensive reading is one of a range of activities that can be used in a language learning course. Ideally, the choice of activities to go into a course should be guided by principles which are well supported by research. Similarly, the way each of those activities is used should be guided by well-justified principles. In this article, we look at…

    Application of microcurrents of bioresonance may allow protein aggregates lysis and a related enhancement of lymphatic drainage. Combining bioresonance with transcutaneous passage of active principles, by means of skin electroporation, microcirculation and clearance of connective tissues may be theoretically activated. A pilot study on an electro-medical device which includes these two technologies (Transponder(®)), has been performed on patients affected by lymphedema (LYM) and/or lipedema (LIP) of the lower limbs. Eight patients affected by primary or secondary unilateral LYM or LIP were submitted to six consecutive daily sessions with the medical device; the first two sessions were performed by a trained physiotherapist, whilst the following four sessions were self-administered by the patients themselves at home (who were educated about the technique). Magnesium silicate was delivered transcutaneously by means of the device at each session. Pre-post-treatment assessment included: 1) limb volumetry by means of tape measurement; 2) segmental multifrequency bioimpedance spectroscopy for fluid changes, with L-DEX measurement; 3) visual analogue scale (VAS) (0-10 score) questionnaire for related symptoms. All the patients completed the scheduled treatment. After the treatment the mean volume of the whole limb decreased from 9462.85 (±3407.02) to 9297.37 cc (±3393.20), which accounts for a 165.48 cc (2%) reduction after six days of treatment. The pre/post-treatment VAS mean score changes were: heaviness from 4.57±3.46 to 2.43±2.57 (-47%), dysesthesias from 1.71±2.63 to 0.71±1.50 (-58%), pain from 1.57±2.57 to 0.57±0.79 (-64%). Diuresis VAS measurement passed from 7.43±1.81 to 8.57±0.98 (15% increase). The average L-DEX percentage reduction was 21%. No side effects were reported and a good patients' compliance was recorded. The preliminary data of this pilot study show that the combination of microcurrents of bioresonance with transdermal delivery of active

    We employed streptozotocin-induced diabetic rats (STZ-diabetic rats) as type 1 diabetes-like animal models to investigate the mechanism(s) of antihyperglycemic action produced by syringin, an active principle purified from the rhizome and root part S of ELEUTHEROCOCCUS SENTICOSUS (Araliaceae). Bolus intravenous (i. v.) injection of syringin dose-dependently decreased the plasma glucose of STZ-diabetic rats in 30 minutes in a way parallel to the increase of plasma beta-endorphin-like immunoreactivity (BER). Syringin enhanced BER release from the isolated adrenal medulla of STZ-diabetic rats in a concentration-dependent manner from 0.001 to 10 micromol/l. Bilateral adrenalectomy in STZ-diabetic rats eliminated the activities of syringin (1 mg/kg, i. v.) including the plasma glucose-lowering effect and the plasma BER-elevating effect. Also, syringin failed to lower plasma glucose in the presence of micro-opioid receptor antagonists and/or in the micro-opioid receptor knockout diabetic mice. In conclusion, the obtained results suggest that syringin can enhance the secretion of beta-endorphin from adrenal medulla to stimulate peripheral micro-opioid receptors resulting in a decrease of plasma glucose in diabetic rats lacking insulin.

    Density-functional theory (DFT) was employed in a first-principles study of the effects of pressure on the Raman-active modes of zircon (ZrSiO4), using both the generalized gradient and local density approximations (GGA and LDA, respectively). Beginning with the equilibrium structure at zero pressure, we conducted a calibration of the effect of pressure in a manner procedurally similar to an experimental calibration. For pressures between 0 and 7 GPa, we find excellent qualitative agreement of frequency-pressure slopes partial ω /partial P calculated from GGA DFT with results of previous experimental studies. In addition, we were able to rationalize the ω vs. P behavior based on details of the vibrational modes and their atomic displacements. Most of the partial ω /partial P slopes are positive as expected, but the symmetry of the zircon lattice also results in two negative slopes for modes that involve slight shearing and rigid rotation of SiO4 tetrahedra. Overall, LDA yields absolute values of the frequencies of the Raman-active modes in good agreement with experimental values, while GGA reproduces the shift in frequency with pressure especially well.

    Due to the deep socioeconomic implications, induced seismicity is a timely and increasingly relevant topic of interest for the general public. Cases of induced seismicity have a global distribution and involve a large number of industrial operations, with many documented cases from as far back to the beginning of the twentieth century. However, the sparse and fragmented documentation available makes it difficult to have a clear picture on our understanding of the physical phenomenon and consequently in our ability to mitigate the risk associated with induced seismicity. This review presents a unified and concise summary of the still open questions related to monitoring, discrimination, and management of induced seismicity in the European context and, when possible, provides potential answers. We further discuss selected critical European cases of induced seismicity, which led to the suspension or reduction of the related industrial activities.

    Full Text Available The article is aimed at studying the organization of foreign economic activity of industrial enterprise in case of introduction of project approach to its management. New conditions of doing business in terms of aircraft building enterprises, consisting in the transition to production according to international standards, require a modern approach to the solution of the range of issues. In conditions of limited internal financial resources of company and high expenses connected with entering the foreign market, it is extremely important to define the priority directions of foreign economic activity and the most optimal mechanisms of its organization and management. The functioning of the sphere of foreign economic activity of industrial enterprise in case of introduction of project approach to management has been analyzed. The essence, features and the main parameters of project approach as a means of increasing the competitiveness of enterprise have been defined. Priorities of the large-scale enterprise development strategy have been analyzed and suggested by means of carrying out the project method of organization of foreign economic activity.

    Neutron induced (n, f)-radiography has been used for assessment of radioactive impact on biota by industrial wastes and exhalation. The objects analyzed were tree leaves which can serve the natural seasonal microelements collectors. Sampling was made in the urban area with two main industrial plants - on the processing of atomic raw material and production of mineral fertilizer. The samples were analyzed by neutron activation analysis (NAA) and neutron induced (n, f)-radiography. The latter technique was used for the study of uranium distribution in a leaf surface. A procedure of the technique was that a detector foil (LEXAN) in a tied contact with a sample surface was subject to thermal neutron exposure in our WWR-SM nuclear reactor. Fission fragments from the 235U(n, f) reaction form radiation damages - tracks - in the surface layer of the detector. Due to close contact of the detector to the sample surface, location of tracks is consistent to location of the determined element. This makes it possible to get a picture of surface distribution of the element and, thus, to get an idea on genesis of pollution with this element. There are two principal ways for intake of pollutant elements in plants, namely, through the root system from the soil, and through the aerosol, dust and/or rain deposition on leaves. Presence of dense track spots like clusters or stars in the produced radiographs asserts their genesis was due to industrial disposal and exhalation. The average uranium concentrations in the leaves cover the range of 0.026 to 0.83 ppm. Based on the experimental data, uranium mapping of the explored territory has been made. Epicenter of the highest uranium level field was spatially consistent to location of the industrial plants, and, therefore, most probably, was generated by their activity

    Nuclear industry pays a particular attention to structures integrity problems: well-aware of the possible catastrophic consequence of a major accident, everything is carried out to minimise the risk of such a situation. From the design, and during all the operating life of the plant, a high level of safety is required and checks by the safety authorities, on the basis of reports made by the operator. These two entities ask for R and D activities to support the improvement of the knowledge of the phenomena already identified (as in the case of the vessel of the PWR) or to bring some element of understanding to situation not considered yet, up to the first incident (as in 1998 with the fatigue problems in the thermal mixing zone, at the origin of the Civaux arrest). Among the CEA teams concerned with these problems, the Laboratory of the Structures Integrity and of Normalisation aims to study the integrity problems in metallic nuclear structures leaning on exceptional experimental means: the RESEDA platform allows the realisation of large-scaled tests on analytical tests (representative of analysed phenomena) to reproduce the industrial situation, linked to various and accurate equipment for the measures and the analyses. Three industrial thematics represent to main part of my research activities at CEA in the fracture mechanics field: - the industrial case of the PWR vessel is related to brittle fracture of the ferritic steels, - the piping components, related to ductile tearing and fracture in the brittle-to-ductile domain, - the high temperature fracture mechanics for the components submitted to very complex loadings.

    LC50-experiments have been conducted using guppies subjected to 72 industrial pollutants. The correlation of the LC50 with several expressions of the hydrophobicity of these chemicals has been studied. Calculated log Poct-values appeared to satisfy more than HPLC retention indices, solubility data or molecular connectivity indices. One QSAR, with log Poct as the only variable, gave good estimations of the toxicity of most of the tested compounds with log Poct less than 6. No LC50 could be determined for solutions of compounds with log Poct greater than 6.

    With the introduction of potential reduced exposure products (PREPs) and the interest in studying tobacco harm reduction, sound research and surveillance are needed to examine and understand the distribution and availability of PREPs in communities, as well as the tobacco industry's marketing practices surrounding these products. We examined the availability and marketing of PREPs in a national sample of tobacco retail stores. We also compared the price of PREPs to those of premium brand cigarettes and examined the distribution of PREPs in comparison with premium brand cigarettes by store type, urbanization, region, and race/ethnicity. We found that PREPs are not widely available, are priced similarly to leading cigarette brands, and have few promotional offers. We also found some significant differences in the distribution of PREPs and cigarettes, as well as in the distribution of Ariva and Omni, by store type and community demographics. The fact that this study used data collected nationally emphasizes the importance of these findings and helps shed some light on the tobacco industry's PREP marketing strategies. This study's national sample provides a unique perspective that needs to be replicated if and when other PREPs are widely marketed.

    It has been 15 years since China dominated the rare earth permanent magnet market in 2001. The annual output of sintered Nd-Fe-B magnets in China reached a new record of 126,300 tonnages in 2015 while the output in 2001 is only 6,500 tonnages. The average growth rate from 2001 to 2015 is about 23.5% though the output in 2012 suffers a deep drop due to the well known rare earth crisis in 2011. Currently, the RE magnet production capability in China seems to be over developed compared to actual requirements. Needless to say the oversupply situation implies a hard time for RE magnet manufacturers due to the fierce competition but maybe a good time for the whole industry. The motivation for a company to develop new technology and more competitive products with better performance and/or lower costs is greatly enhanced. The objective of this paper is to give a general picture of Chinese REPM industry and market including the output capability, the status of competition, the development of magnet application and the market trend. Some new research hot points potentially being applied, for example the Cerium magnet, will be introduced as well.

    The process of moving material manually has the potential for injury to workers. The risk of injury will increase if we do not pay attention to the working conditions. The purpose of this study is to assess and analyze the injury risk level in manual handling material activity, as well as to improve the condition. The observed manual material handling activities is pole lifting and goods loading. These activities were analyzed using Job Strain Index method, Rapid Entire Body Assessment, and Chaffin’s 2D Planar Static Model. The results show that most workers who perform almost all activities have a high level of risk level with the score of JSI and REBA exceeds 9 points. For some activities, the estimated compression forces in the lumbar area also exceed the standard limits of 3400 N. Concerning this condition, several suggestions for improvement were made, improving the composition of packing, improving body posture, and making guideline posters.

    2015-07-05

    The aim of this study is to develop an at-line near infrared (NIR) method for the rapid and simultaneous determination of four structurally similar active pharmaceutical ingredients (APIs) in powder blends intended for the manufacturing of tablets. Two of the four APIs in the formula are present in relatively small amounts, one at 0.95% and the other at 0.57%. Such small amounts in addition to the similarity in structures add significant complexity to the blend uniformity analysis. The NIR method is developed using spectra from six laboratory-created calibration samples augmented by a small set of spectra from a large-scale blending sample. Applying the quality by design (QbD) principles, the calibration design included concentration variations of the four APIs and a main excipient, microcrystalline cellulose. A bench-top FT-NIR instrument was used to acquire the spectra. The obtained NIR spectra were analyzed by applying principal component analysis (PCA) before calibration model development. Score patterns from the PCA were analyzed to reveal relationship between latent variables and concentration variations of the APIs. In calibration model development, both PLS-1 and PLS-2 models were created and evaluated for their effectiveness in predicting API concentrations in the blending samples. The final NIR method shows satisfactory specificity and accuracy. Copyright © 2015 Elsevier B.V. All rights reserved.

    Hydrolytic enzymes released by the microorganisms in activated sludge are responsible for the organic matter degradation there; however, the optimal extraction procedure of this valuable resource has not been well established until now. In this study protease and lipase were extracted from activated sludge using ultrasound disintegration combined with a nonionic detergent (Triton X-100) and cation-exchange resin (CER) in combination for the extraction of protease and lipase. It was observed that the concentration of 0.1% and 1% Triton X-100 has a strong influence for the extraction of lipase and protease respectively. Closer study of the enzyme extraction process is essential for different enzymes from activated sludge process.

    Increased ethoxyresorufin-O-deethylase (EROD) activity is a sensitive biomarker of exposure to the chemicals which activate the aryl hydrocarbon receptor (AhR) and induce the cytochrome P450 system, such as many polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and polychlorinated biphenyls (PCBs). Pulp bleaching was one of the main sources of PCDDs and PCDFs until elemental chlorine free (ECF) and total chlorine free bleaching processes since 1990s have remarkably decreased but not completely eliminate discharges of these chemicals. In addition, historically contaminated sediments may act as a source of these persistent contaminants. In this study, the contamination history and recovery of a watercourse heavily loaded by the chemical wood industry were studied by analyzing PCDDs, PCDFs and PCBs from vertical sediment samples and by measuring hepatic EROD activity from rainbow trout intraperitoneally dosed with the sediment extracts. No PCDDs or PCDFs were found above the chromatographic limit of detection from the study area and only small amounts of PCB congeners 101, 138, 153, and 180 were present. No increased EROD activity was observed in fish indicating the absence of any AhR-activating compounds in the surface sediment, to about 15 cm depth, representing about the last 20 years when kraft pulping and ECF bleaching with activated wastewater treatment have been used. It can be concluded that nowadays organochlorines and other AhR-ligands do not harm the previously heavily polluted watercourse. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available The article addresses basic issues associated with the economic analysis of liability in tort principles. The deliberations focus on an attempt to define the economic and social consequences of introducing various combinations of principles of tortious liability for damage suffered as a result of the activities of one entity borne in the goods of another. Lack of liability situations are treated in some detail as well as liability based on the principle of risk and the principle of fault. The analyses were conducted based on unilateral and bilateral models. Factors coming into play in determining the economically effective level of carefulness in actions are discussed. A series of other factors of significant relevance for the choice of an optimal principle of liability from the economic point of view are also highlighted. In this context the role of the level of activity of entities, availability of insurance policies and costs associated with pursuing compensation claims are discussed.

    Spices, like vegetables, fruit, and medicinal herbs, are known to possess a variety of antioxidant effects and other biological activities. Phenolic compounds in these plant materials are closely associated with their antioxidant activity, which is mainly due to their redox properties and their capacity to block the production of reactive oxygen species. More recently, their ability to interfere with signal transduction pathways involving various transcription factors, protein kinases, phosphatases, and other metabolic enzymes has also been demonstrated. Many of the spice-derived compounds which are potent antioxidants are of great interest to biologists and clinicians because they may help protect the human body against oxidative stress and inflammatory processes. It is important to study the bioactive compounds that can modulate target functions related to defence against oxidative stress, and that might be used to achieve health benefits individually. In the present review, an attempt has been made to summarize the most current scientific evidence about the in vitro and in vivo effects of the bioactive compounds derived from herbs and spices, focused on anti-inflammatory and antioxidant effects, in order to provide science-based evidence for the traditional uses and develop either functional foods or nutraceuticals.

    A comparison between two digestion methods of hot plate Hossner (total-total) and USEPA method 3051 (total-recoverable) was carried out to suggest a proper method for determining nine heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) content of three urban soils affected by mining (Mahd AD'Dahab) or industrial activities (Riyadh and Jubail) at Saudi Arabia. The results showed no significant differences between two digestion methods for Cd, Cu, Pb and Zn in soils affected by mining and for Cr, Cu, Pb and Zn in soils affected by industrial activities. Additionally, lower biases were obtained between two methods for metals Cd, Cu, Zn and Pb in the urban soil samples from mining area with the percent biases of -16.5%, +6.24%, -12.4% and +24.1%, respectively. The results also revealed that only Cu and Zn in the soil samples from Riyadh were extracted satisfactorily using USEPA 3051 with low biases of +5.69% and -9.61%, respectively. Meanwhile, only Pb in soil samples from Jubail showed lower baise between two methods with satisfactory biase of -8.07%. The correlation coefficients were significant between total-recoverable and total-total concentrations for Cu (r = 0.66), Pb (r = 0.72) and Cd (r = 0.65) in soil samples from mining area. Overall, concentrations of Co, Cr, Fe, Mn, and Ni that may show soil background concentrations were found higher by Hossner method than by USEPA 3051; thus, this suggests the addition of hydrofluoric acid (HF) is necessary for the determination of lithogenic metal concentrations. It could be concluded that the USEPA 3051 may be recommended and applied for total Cd, Cu, Pb and Zn originated from anthropogenic source in mining and industrial areas.

    2016-01-01

    In this fundamental book the authors devise a framework that describes the working of the brain as a whole. It presents a comprehensive introduction to the principles of Neural Information Processing as well as recent and authoritative research. The books´ guiding principles are the main purpose of neural activity, namely, to organize behavior to ensure survival, as well as the understanding of the evolutionary genesis of the brain. Among the developed principles and strategies belong self-organization of neural systems, flexibility, the active interpretation of the world by means of construction and prediction as well as their embedding into the world, all of which form the framework of the presented description. Since, in brains, their partial self-organization, the lifelong adaptation and their use of various methods of processing incoming information are all interconnected, the authors have chosen not only neurobiology and evolution theory as a basis for the elaboration of such a framework, but also syst...

    Curcumin, the yellow coloring pigment of turmeric is produced industrially from turmeric oleoresin. The mother liquor after isolation of curcumin from oleoresin known as curcumin removed turmeric oleoresin (CRTO) was extracted three times with n-hexane at room temperature for 30 min to obtain turmeric oil. The turmeric oil was subjected to fractional distillation under vacuum to get two fractions. These fractions were tested for antifugal activity against Aspergillus flavus, A. parasiticus, Fusarium moniliforme and Penicillium digitatum by spore germination method. Fraction II was found to be more active. The chemical constituents of turmeric oil, fraction I and fraction II were determined by GC and identified by GC-MS. Aromatic turmerone, turmerone and curlone were major compounds present in fraction II along with other oxygenated compounds.

  1. Methanol Synthesis over Cu/ZnO/Al2O3: The Active Site in Industrial Catalysis

    2012-03-28

    Unlike homogeneous catalysts, heterogeneous catalysts that have been optimized through decades are typically so complex and hard to characterize that the nature of the catalytically active site is not known. This is one of the main stumbling blocks in developing rational catalyst design strategies in heterogeneous catalysis. We show here how to identify the crucial atomic structure motif for the industrial Cu/ZnO/Al{sub 2}O{sub 3} methanol synthesis catalyst. Using a combination of experimental evidence from bulk-, surface-sensitive and imaging methods collected on real high-performance catalytic systems in combination with DFT calculations. We show that the active site consists of Cu steps peppered with Zn atoms, all stabilized by a series of well defined bulk defects and surface species that need jointly to be present for the system to work.

    Lakes Superior, Huron, Michigan, Ontario, and Erie together form North America's Great Lakes, a region that contains 20% of the world's fresh surface water and is home to roughly one quarter of the U.S. population (Figure 1). Supporting a $4 billion sport fishing industry, plus $16 billion annually in boating, 1.5 million U.S. jobs, and $62 billion in annual wages directly, the Great Lakes form the backbone of a regional economy that is vital to the United States as a whole (see http://www.miseagrant.umich.edu/downloads/economy/11-708-Great-Lakes-Jobs.pdf). Yet the grandeur and importance of this freshwater resource are little understood, not only by people in the rest of the country but also by many in the region itself. To help address this lack of knowledge, the Centers for Ocean Sciences Education Excellence (COSEE) Great Lakes, supported by the U.S. National Science Foundation and the National Oceanic and Atmospheric Administration, developed literacy principles for the Great Lakes to serve as a guide for education of students and the public. These “Great Lakes Literacy Principles” represent an understanding of the Great Lakes' influences on society and society's influences on the Great Lakes.

    2017-12-01

    Full Text Available Three main components of the concept of sustainable development are analyzed: economic development, social inclusion and environmental conditions. The expediency of introducing the principles of sustainable development in enterprises of the fat and oil industry is grounded. The state of Ukraine’s agriculture is studied, and its influence on the depletion of natural resources is determined. The evolution of the development of the oil and fat industry, its current state and role for the economy of Ukraine are considered. It is found that for successful functioning of the principles of sustainable development, enterprises of the oil and fat industry need to introduce an export duty for the export of rapeseeds and soybeans, a more stringent control of incoming raw materials and international certification of the enterprises. Recommendations are given on the development of innovation activity, attraction of investments and new approaches in logistics.`

    2014-01-01

    Tobacco companies are increasingly turning to trade and investment agreements to challenge measures aimed at reducing tobacco use. This study examines their efforts to influence the Trans-Pacific Partnership (TPP), a major trade and investment agreement which may eventually cover 40% of the world's population; focusing on how these efforts might enhance the industry's power to challenge the introduction of plain packaging. Specifically, the paper discusses the implications for public health regulation of Philip Morris International's interest in using the TPP to: shape the bureaucratic structures and decision-making processes of business regulation at the national level; introduce a higher standard of protection for trademarks than is currently provided under the Agreement on Trade Related Aspects of Intellectual Property Rights; and expand the coverage of Investor-State Dispute Settlement which empowers corporations to litigate directly against governments where they are deemed to be in breach of investment agreements. The large number of countries involved in the TPP underlines its risk to the development of tobacco regulation globally. PMID:23788606

    Systematic improvement of the safety of industrial vehicles will require the enhanced use of intelligent mechatronic systems, especially those that ensure higher directional stability. Further, improved tyres are required for making full use of these systems. Research on tyre improvements should focus on directional stability without neglecting classic parameters like wear, grip, and comfort. Last but not least, all systems should be available at reasonable cost. [German] Der systematische Weg, um die aktive Sicherheit von Nutzfahrzeugen weiter zu verbessern, wird mehr und mehr den Einsatz von intelligenten mechatronischen Systemen erfordern, besonders bei Systemen fuer die Verbesserung von Fahrstabilitaet von Einzelfahrzeugen und Lastzuegen. Hier spielt in kritischen fahrdynamischen Situationen aber auch die Leistungsfaehigkeit des Reifens eine grosse Rolle. Die Vorteile solcher Sicherheitssysteme koennen deshalb nur genutzt werden, wenn die Leistungsfaehigkeit der Reifen weiter gesteigert werden kann, d.h. die Betonung bei der Reifenentwicklung fuer Nutzfahrzeuge muss auf der Erhoehung der uebertragbaren Seiten- und Laengskraefte unter Beibehaltung des heutigen Schraegwinkel - und Schlupfniveaus liegen. Selbstverstaendlich darf eine solche Weiterentwicklung nicht die ueblichen Reifenparameter, wie z.B. Verschleiss, Rollwiderstand und Komfort negativ beeinflussen. Ein abschliessender Aspekt in diesem Prozess, den man nicht ignorieren kann, ist der Einsatz aller sicherheitsbezogenen Systeme zu einem vernuenftigen und akzeptablen Preis, wobei gleichzeitig die ganzheitliche Oekonomie des Nutzfahrzeugs positiv beeinflusst werden sollte.

    Catalán-Vázquez, Minerva; Riojas-Rodríguez, Horacio

    2015-06-01

    Analyze how gender inequity manifests in contexts of poverty in different environmental risk scenarios in Mexico. Qualitative design based on six discussion groups and 54 in-depth interviews with women from six exposed communities: two to environmental manganese in a mining district, two in an industrial corridor, and two bordering a sanitary landfill. A document review of environmental and health studies in each area was done to relate them to the women's perspective on the problem. In the three case studies, by gender roles, women stay at home and do housework and, therefore, are subject to intense environmental exposure when carrying out their daily tasks, such as house cleaning. Interview and discussion group results were found to be related to epidemiological study results. In the case of the mining district, women's perceptions are consistent with study comments on adverse cognitive effects of manganese exposure. In all three cases, there are serious limitations on women's political participation in environmental risk management. Due to conditions of inequity, women are highly exposed to environmental health risks and their social participation in solving environmental problems is quite limited. These results have social and environmental policy implications in the areas studied, especially with regard to risk assessment, management, and communication.

    It is very important to follow the Precautionary Principles with regard to genetics because of its fast development and of its impact in the public imaginer. In that regard gene grafts, OGM or recombinant drugs are pre-eminently be suspected to transmit human or animal viruses and/or to induce severe allergies. Pharmaceutical Industry has conducted large reflexions on such problems and are using drastic rules to prevent them. By contrast, academic research laboratories are handicapped by the problem of fund seeking. At the genetic disease level and mainly because the fast development of Predictive Medicine, patient and family councelling requires a great lot of reflexion and carefulness. Memorization of the presence of abnormal genes in the history of families also constitutes an important problem. We believe that, to be in accordance with the Precautionary Principles, an important work of formation and information is required.

  18. Bioremediation Approaches in a Laboratory Activity for the Industrial Biotechnology and Applied Microbiology (IBAM Course

    Directory of Open Access Journals (Sweden)

    L. Raiger Iustman

    2013-03-01

    Full Text Available Industrial Biotechnology and Applied Microbiology is an optional 128h-course for Chemistry and Biology students at the Faculty of Sciences, University of Buenos Aires, Argentina. This course is usually attended by 25 students, working in teams of two. The curriculum, with 8 lab exercises, includes an oil bioremediation practice covering an insight of bioremediation processes: the influence of pollutants on autochthonous microbiota, biodegrader isolation and biosurfactant production for bioavailability understanding. The experimental steps are: (A evaluation of microbial tolerance to pollutants by constructing pristine soil microcosms contaminated with diesel or xylene and (B isolation of degraders and biosurfactant production analysis. To check microbial tolerance, microcosms are incubated during one week at 25-28ºC. Samples are collected at 0, 4 and every 48 h for CFU/g soil testing. An initial decrease of total CFU/g related to toxicity is noticed. At the end of the experiment, a recovery of the CFU number is observed, evidencing enrichment in biodegraders. Some colonies from the CFU counting plates are streaked in M9-agar with diesel as sole carbon source. After a week, isolates are inoculated on M9-Broth supplemented with diesel to induce biosurfactant production. Surface tension and Emulsification Index are measured in culture supernatants to visualize tensioactive effect of bacterial products. Besides the improvement in the good microbiological practices, the students show enthusiasm in different aspects, depending on their own interests. While biology students explore and learn new concepts on solubility, emulsions and bioavailability, chemistry students show curiosity in bacterial behavior and manipulation of microorganisms for environmental benefits.

    Volatile oils obtained from both the liquid medium after incubation (MAI) and liquid medium before incubation (MBI) during the cultivation process of Lactobacillus brevis were isolated by hydrodistillation (HD) and analyzed to determine the utility of the liquid waste. The composition of the volatile oils was analyzed by capillary gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). In total, 55 and 36 compounds were detected in the volatile oils from MAI (MAI oil) and MBI (MBI oil), respectively. The principle components of MAI oil were N-containing compounds, including 2,3-dimethylpyrazine (16, 37.1 %), methylpyrazine (4, 17.1 %). The important aroma-active compounds in the oils were detected by GC-Olfactometry (GC-O), and their intensity of aroma were measured by aroma extract dilution analysis (AEDA). Expressly, pyrazine compounds were determined as key aroma components; in particular, 2,5-dimethylpyrazine and 2,3-dimethylpyrazine were the most primary aroma-active compound in MAI oil. These results imply that the waste medium after incubation of L. brevis may be utilized as a source of volatile oils.

    2018-02-05

    A novel Liquid Chromatography-tandem mass spectrometry (LC-MS/MS) method is presented for the quantitative determination of two potential genotoxic impurities (PGIs) in rabeprazole active pharmaceutical ingredient (API). In order to overcome the analytical challenges in the trace analysis of PGIs, a development procedure supported by Quality-by-Design (QbD) principles was evaluated. The efficient separation between rabeprazole and the two PGIs in the shortest analysis time was set as the defined analytical target profile (ATP) and to this purpose utilization of a switching valve allowed the flow to be sent to waste when rabeprazole was eluted. The selected critical quality attributes (CQAs) were the separation criterion s between the critical peak pair and the capacity factor k of the last eluted compound. The effect of the following critical process parameters (CPPs) on the CQAs was studied: %ACN content, the pH and the concentration of the buffer salt in the mobile phase, as well as the stationary phase of the analytical column. D-Optimal design was implemented to set the plan of experiments with UV detector. In order to define the design space, Monte Carlo simulations with 5000 iterations were performed. Acceptance criteria were met for C 8 column (50×4mm, 5μm) , and the region having probability π≥95% to achieve satisfactory values of all defined CQAs was computed. The working point was selected with the mobile phase consisting ‎of ACN, ammonium formate 11mM at a ratio 31/69v/v with pH=6,8 for the water phase. The LC protocol was transferred to LC-MS/MS and validated according to ICH guidelines. Copyright © 2017 Elsevier B.V. All rights reserved.
