    2015-06-01

    Full Text Available Internal control is indissolubly linked to business and accounting. Throughout history, domestic and international trade has grown exponentially, which has led to an increasing complexity of internal control, to new methods and techniques to control the business. The literature has presented the first models of internal control in the Sumerian period (3600 - 3200 BC, and the emergence and development of internal control in Egypt, Persia, Greek and Roman Empire, in the Middle Ages till modern times. The purpose of this article is to present the models of internal control in Romania, starting from the principles of the classical model of internal control (COSO model. For a better understanding of the implication of internal control in terms of public and private sector, I have structured the article in the following parts: (a the definition of internal control in the literature; (b the presentation of the COSO model; (c internal control and internal audit in public institutions; (d internal control issues in accounting regulations on the individual and consolidated annual financial statements; (e internal / managerial control; (f conclusions.

    American Institute of Certified Public Accountants

    2013-01-01

    Issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), the 2013 Internal Control – Integrated Framework(Framework) is expected to help organizations design and implement internal control in light of many changes in business and operating environments since the issuance of the original Framework in 1992. The new Framework retains the core definition of internal control and the five components of internal control, and it continues to emphasize the importance of management judgment in designing, implementing, and conducting a system of internal control, and in assessing its effectiveness. It broadens the application of internal control in addressing operations and reporting objectives, and clarifies the requirements for determining what constitutes effective internal control.

  11. Internal quality control: best practice.

    Science.gov (United States)

    Kinns, Helen; Pitkin, Sarah; Housley, David; Freedman, Danielle B

    2013-12-01

    There is a wide variation in laboratory practice with regard to implementation and review of internal quality control (IQC). A poor approach can lead to a spectrum of scenarios from validation of incorrect patient results to over investigation of falsely rejected analytical runs. This article will provide a practical approach for the routine clinical biochemistry laboratory to introduce an efficient quality control system that will optimise error detection and reduce the rate of false rejection. Each stage of the IQC system is considered, from selection of IQC material to selection of IQC rules, and finally the appropriate action to follow when a rejection signal has been obtained. The main objective of IQC is to ensure day-to-day consistency of an analytical process and thus help to determine whether patient results are reliable enough to be released. The required quality and assay performance varies between analytes as does the definition of a clinically significant error. Unfortunately many laboratories currently decide what is clinically significant at the troubleshooting stage. Assay-specific IQC systems will reduce the number of inappropriate sample-run rejections compared with the blanket use of one IQC rule. In practice, only three or four different IQC rules are required for the whole of the routine biochemistry repertoire as assays are assigned into groups based on performance. The tools to categorise performance and assign IQC rules based on that performance are presented. Although significant investment of time and education is required prior to implementation, laboratories have shown that such systems achieve considerable reductions in cost and labour.

  14. International security and arms control

    International Nuclear Information System (INIS)

    Ekeus, R.

    2000-01-01

    The end of the cold war also ended the focus on the bilateral approach to arms control and disarmament. Key concepts of security needed to be revisited, along with their implications for the disarmament and arms control agenda. Though there is currently a unipolar global security environment, there remain important tasks on the multilateral arms control agenda. The major task is that of reducing and eliminating weapons of mass destruction, especially nuclear weapons. The author contends that maintaining reliance on the nuclear-weapons option makes little sense in a time when the major Powers are strengthening their partnerships in economics, trade, peacemaking and building.

  17. Corruption, fraud and internal control

    Directory of Open Access Journals (Sweden)

    Luminiţa IONESCU

    2010-12-01

    Full Text Available The economic crunch created a specific context for activity and profitability failing. The corruption is more and more common in our days. In the same time, the amount of money lost by businesses and the public sector to larger frauds increased last year to unthinkable limits. The shareholders expect the directors to take care to protect their company’s assets. This is why the financial controller has a very important role in each organization. The techniques to detect corruption or a fraud are developing every year. Thus, the introduction of computerized accounting has created the opportunities to conduct very comprehensive tests at relatively little cost. However, the fraudsters became more and more clever, and the controllers are responsible for the prevention and detection of fraud. The procedures that controllers should adopt with regard to fraud depend on the risk that fraud could occur and remain undetected and also the risk of that fraud impairing the truth and fairness of the statement.

    In this paper we obtain two exact internal controllability results of Maxwell's equations in a general region by using multiplier techniques. The first one is exact controllability in a short time, in which we obtain the 'optimal' (observability) estimates when the location and the shape of the controller is fixed. What happens if we allow the controller to change? Under some conditions, we show that by doing that the system can be exactly controllable within any given time duration, which is our second exact controllability result

    2010-06-01

    Full Text Available Companies can gain additional efficiency in designing and implementing or assessing internal control by focusing on only those financial reporting objectives directly applicable to the company’s activities and circumstances, taking a risk based approach to internal control. It is important for any organization to have reliable financial data for internal decision-making purpose. Financial information is often useful in many internal decisions such as product or service pricing. This is why the most important function of the controller is to create and maintain the corporate financial control system. Today’s corporation operates in an increasingly complex environment and the controller’s role is to advice the management of current or future problems of the business environment or to prevent the fraud.

Since the final decision in the form of an exhaustive list and universal principles of internal control is no scientific research continues these principles. It is necessary to examine the logic of the main provisions of the organization's internal control due consideration of the requirements of international practice controls and propose principles of internal control. For this purpose, conducted a critical analysis of the main provisions of internal controls contained in the publications and in the regulations on internal control proceedings. Synthesis of articles of authors of lead scientific and practical journal Ukraine "Accounting and Auditing" for the 1994-2015 biennium pointed out that despite the coverage of current journal articles provisions, principles, requirements, rules and other modern techniques. On internal control and comprehensive set of reasonable response to the organization and classification of internal control is absent. This leads to continue the search key components of the organization's internal control. The above basic concepts in publications on the organization of internal control were used in the formation of a set of principles of control.

    Human-wildlife conflicts are commonly addressed by excluding, relocating, or lethally controlling animals with the goal of preserving public health and safety, protecting property, or conserving other valued wildlife. However, declining wildlife populations, a lack of efficacy of control methods in achieving desired outcomes, and changes in how people value animals have triggered widespread acknowledgment of the need for ethical and evidence-based approaches to managing such conflicts. We explored international perspectives on and experiences with human-wildlife conflicts to develop principles for ethical wildlife control. A diverse panel of 20 experts convened at a 2-day workshop and developed the principles through a facilitated engagement process and discussion. They determined that efforts to control wildlife should begin wherever possible by altering the human practices that cause human-wildlife conflict and by developing a culture of coexistence; be justified by evidence that significant harms are being caused to people, property, livelihoods, ecosystems, and/or other animals; have measurable outcome-based objectives that are clear, achievable, monitored, and adaptive; predictably minimize animal welfare harms to the fewest number of animals; be informed by community values as well as scientific, technical, and practical information; be integrated into plans for systematic long-term management; and be based on the specifics of the situation rather than negative labels (pest, overabundant) applied to the target species. We recommend that these principles guide development of international, national, and local standards and control decisions and implementation. © 2017 The Authors.

  19. Turbine Energy Evaluation by internal dimensional control

    International Nuclear Information System (INIS)

    Mediavilla, F.

    2000-01-01

    To maintain the optimum thermal performance in a high level throughout the life of the turbines requires a good testing program, proper analysis of the test data, and a steam path audit during turbine overhauls. If from operating data analysis collected during the performance test before the outage shows that the efficiency of the turbine is coming down, the steam path audit, that is an internal inspection and a dimensional control of the internals, identity and quantity causes of performance degradation like, seal leakages, excessive clearances, solid particle erosion damages, blades deposits and other losses. The steam path audit assigns the heat rate penalties associated with each of these individual losses to the total degradation. This are used to make cost-effective maintenance decisions during the course of the overhaul. After repairs, a closing steam path audit is conducted during the re assembly of the turbine in order to predict return to service condition of the machine and to provide a quality control check on outage repairs.

  9. International pollution control: Cooperative versus noncooperative strategies

    International Nuclear Information System (INIS)

    Dockner, E.J.; Van Long, N.

    1993-01-01

    International pollution control involving two neighboring countries is modeled as a simple two-player dynamic game. Each country produces a good that is consumed by domestic households. Production of each consumption good results in emissions of pollutants. Households in each country derive utility from the consumption of the domestically produced good but incur costs through the total stock of pollution (stock externality). In this setting we characterize cooperative as well as noncooperative pollution control strategies of the governments of the two countries that maximize the discounted stream of net benefits of a representative consumer. It turns out that when the governments are restricted to use linear strategies noncooperative behavior results in overall losses for both countries. If, on the contrary, governments use nonlinear Markov-perfect strategies and the discount rate is small enough a Pareto-efficient steady-state pollution stock can be supported as a differentiable subgame-perfect equilibrium. Thus, the emergence of first-best solutions (cooperative outcomes) does not require any institutional arrangements (threats, retaliation, etc.) but can be brought about through the use of nonlinear Markov-perfect equilibrium strategies. 20 refs., 1 tab

    Full Text Available This paper assessed factors that influence the internal controls in ensuring good corporate governance in financial institutions in developing economies with special reference to Zimbabwe. The research paper assessed how lack of internal controls affected good corporate governance and aimed to bring out elements of good corporate governance. It emerged that failure to effectively implement internal controls contributed significantly to poor corporate governance. The study discovered that internal control system overrides and the issue of “fact cat” directors also contributed to poor corporate governance. The study recommended that there is need for the board of directors to guarantee an organizational structure that clearly defines management responsibilities, authority and reporting relationships. There is also need to ensure that delegated responsibilities are effectively carried out to ensure compliance with internal controls of the financial institution concerned.

    Full Text Available A simple method has been investigated for the total or partial removal of the effect of non-linear process phenomena in multi-variable feedback control systems. The method is based upon computing the control variables which will drive the process at desired rates. It is shown that the effect of model errors in the linearization of the process can be partly removed through the use of large feedback gains. In practice there will be limits on how large gains can he used. The sensitivity to parameter errors is less pronounced and the transient behaviour is superior to that of ordinary PI controllers.

    Case histories are described in which measurable improvements in the cabin noise environments of the Bell 214B, 206B, and 222 were realized. These case histories trace the noise control efforts followed in each vehicle. Among the design approaches considered, the addition of a fluid pulsation damper in a hydraulic system and the installation of elastomeric engine mounts are highlighted. It is concluded that substantial weight savings result when the major interior noise sources are controlled by design, both in altering the noise producing mechanism and interrupting the sound transmission paths.

    1994-12-31

    Lighting is a central and critical aspect of control in environmental research for plant research and is gaining recognition as a significant factor to control carefully for animal and human research. Thus this workshop was convened to reevaluate the technology that is available today and to work toward developing guidelines for the most effective use of lighting in controlled environments with emphasis on lighting for plants but also to initiate interest in the development of improved guidelines for human and animal research. There are a number of established guidelines for lighting in human and animal environments. Development of new lighting guidelines is necessary for three reasons: (1) recent scientific discoveries show that in addition to supporting the sensation of vision, light has profound nonvisual biological and behavioral effects in both animals and humans; (2) federal regulations (EPACT 1992) are requiring all indoor environments to become more energy efficient with a specific emphasis on energy conservation in lighting; (3) lighting engineers and manufacturers have developed a wealth of new light sources and lighting products that can be applied in animal and human environments. The workshop was aimed at bringing together plant scientists and physical scientists to interact in the discussions. It involved participation of biological scientists involved in studying mechanisms of light reactions and those involved in utilizing lighting for production of plants and maintenance of animals in controlled environments. It included participation of physical scientists from universities and government involved in research as well as those from industry involved in producing lamps and in construction of controlled growth facilities. Selected papers are indexed separately for inclusion in the Energy Science and Technology Database.

    2017-01-01

    Full Text Available Purpose: The study purport to investigate the effectiveness of internal control mechanisms, investigate whether evidence of agency problem is found among banks in Europe and determine how internal controls affect credit risk. Design/methodology/approach: Panel data from 91 banks from 23 European Union countries were studied from 2008-2014. Hausman’s specification test suggest the use of fixed effects estimation technique of GLS. Quantitatively modelled data on 15 variables covering elements of internal controls, objectives of internal controls, agency problem, bank and country specific variables were used. Findings: There is still high credit risk in spite of measures being implemented by the European Central Bank. Banks have individual entity factors that increase or decrease credit risk. The study finds effective internal control systems because objectives of internal controls are achieved and significantly determine credit risk. Agency problem is confirmed due to significant positive relation with credit risk. There is significant effect of internal controls on credit risk with specific variables as risk assessment, return on average risk weighted assets, institutional ownership, bank size, inflation, interest rate and GDP. Research limitations/implications: Missing data prevented the use of strongly balanced panel. The lack of flexibility with using quantitative approach did not allow further scrutiny of the nature of variables. However, statistical tests were acceptable for the model used. The study has implications for management and owners of banks to be warry of agency problem because that provides incentive for reckless high risk transactions that may benefit the agent than the principal. Management must engage in actions that profile the company better and enhances value maximization. Rising default risk has tendency to impair corporate image leading to loss of reputational capital. Originality/value: The study provides the use of

    International Nuclear Information System (INIS)

    Lee, Jong Bok; Heo, Hoon; Cho, Yun Hyun; Ji, Tae Young

    2006-01-01

    Although many methods about the control of irregular external noise have been introduced and implemented, it is still necessary to design a controller that will be more effective and efficient methods to exclude for various noises. Accumulation of errors due to model tracking, internal noises (thermal noise, shot noise and l/f noise) that come from elements such as resistor, diode and transistor etc. in the circuit system and numerical errors due to digital process often destabilize the system and reduce the system performance. New stochastic controller is adopted to remove those noises using conventional controller simultaneously. Design method of a model tracking dual controller is proposed to improve the stability of system while removing external and internal noises. In the study, design process of the model tracking dual stochastic controller is introduced that improves system performance and guarantees robustness under irregular internal noises which can be created internally. The model tracking dual stochastic controller utilizing F-P-K stochastic control technique developed earlier is implemented to reveal its performance via simulation

  2. Specificity of continuous auditing approach on information technology internal controls

    2012-01-01

    Full Text Available Contemporary business world, can not be imagined without the use of information technology in all aspects of business. The use of information technology in manufacturing and non-production companies' activities can greatly facilitate and accelerate the process of operation and control. Because of its complexity, they possess vulnerable areas and provide space for the emergence of accidental and intentional frauds that can significantly materially affect the business decisions made by the companies' management. Implementation of internal controls can greatly reduce the level of errors that can contribute to making the wrong decisions. In order to protect the operating system, the company's management implement an internal audit to periodically examine the fundamental quality of the internal control systems. Since the internal audit, according to its character, only periodically checks quality of internal control systems and information technologies to be reported to the manager, the problem arises in the process of in wrong time reporting the management structures of the business entity. To eliminate this problem, management implements a special approach to internal audit, called continuous auditing.

  3. The importance of domestic law to international arms control

    International Nuclear Information System (INIS)

    Lehman, R.F. II.

    1993-11-01

    Studies of arms control and disarmament tend to focus on political, military, and diplomatic processes. Recently, in the context of the conversion of defense activities to civilian use, the economic aspects of arms control have also received renewed interest. The legal dimension, however, is in need of fresh examination. Both international and domestic law are sailing increasingly in uncharted waters. Recent arms control agreements and related developments in international peacekeeping have expanded the scope of international law and altered how one perceives certain fundamentals, including the principle of national sovereignty. Still, the nation state is largely unchallenged as the primary actor in international affairs. National governments retain near absolute sovereign rights and responsibilities even in an age of trans-national economic integration and codified international norms for human rights, freedom of the press, and the peaceful resolution of disputes. Indeed, the role of domestic law in arms control and disarmament may be more significant now than ever before. A brief review of relationships between arms control and domestic law should illustrate ways in which ones thinking has been underestimating the importance of domestic law. Hopefully, this survey will set the stage properly for the excellent, more detailed case studies by Elinor Hammarskjold and Alan Crawford. Toward that end, this paper will highlight a number of more general, and sometimes provocative, themes. These themes should be kept in mind when those two complementary presentations are considered

  4. International trade agreements: a threat to tobacco control policy.

    Shaffer, E R; Brenner, J E; Houston, T P

    2005-08-01

    International covenants establish a role for governments in ensuring the conditions for human health and wellbeing, which has been recognised as a central human right. International trade agreements, conversely, prioritize the rights of corporations over health and human rights. International trade agreements are threatening existing tobacco control policies and restrict the possibility of implementing new controls. This situation is unrecognised by many tobacco control advocates in signatory nations, especially those in developing countries. Recent agreements on eliminating various trade restrictions, including those on tobacco, have expanded far beyond simply international movement of goods to include internal tobacco distribution regulations and intellectual property rules regulating advertising and labelling. Our analysis shows that to the extent trade agreements protect the tobacco industry, in itself a deadly enterprise, they erode human rights principles and contribute to ill health. The tobacco industry has used trade policy to undermine effective barriers to tobacco importation. Trade negotiations provide an unwarranted opportunity for the tobacco industry to assert its interests without public scrutiny. Trade agreements provide the industry with additional tools to obstruct control policies in both developed and developing countries and at every level. The health community should become involved in reversing these trends, and help promote additional measures to protect public health.

    Full Text Available Corruption represents one of the major causes of poverty all over the world and European Union is fighting against it. In the last few years, the corruption phenomenon registered a high level in some European countries and became one of the most problematic factors for doing business, due to the evolution of the perceived top five global risks: interstate conflict and regional consequences, extreme weather events, failure of national governance, state collapse or crises, high structural unemployment or underemployment              (WEF-Global Risk Report 2015, p. 14. One of the modalities in combating corruption is implementing the internal control and most of the governments and organizations adopted strong control techniques. Most of the control weaknesses are related to the financial procedures and the number of controllers. Some of the controllers do not have enough financial expertise or do not understand the importance of informatics systems.

    2014-04-01

    Full Text Available Beyond the multitude of definitions, internal control is found in the centre of managerial concerns worldwide. This amplification of interest towards internal control has its origin in a series of events, of which two can be mentioned: the growing business complexity and dispersal activity centres, which led to the growth and development of the delegation of competence, the only way which enables the responsible to exercise powers from a distance and entirely, bringing together the components needed by its delegates. Regulatory domain, which has not ceased to expand: laws, regulations, rules, professional constraints, budgetary and social – all these have increasingly limited the decision makers, through a network of rules that must be respected. Consequently, what can be done to be safe from any punishment and to ensure constant watch over the essentials? To answer these questions, and many others, experts in the field have taken initiatives that have enabled them to define with precision the specific internal control and to set goals, creating the famous models: COSO and CoCo.

  20. International trade agreements challenge tobacco and alcohol control policies.

    Science.gov (United States)

    Zeigler, Donald W

    2006-11-01

    This report reviews aspects of trade agreements that challenge tobacco and alcohol control policies. Trade agreements reduce barriers, increase competition, lower prices and promote consumption. Conversely, tobacco and alcohol control measures seek to reduce access and consumption, raise prices and restrict advertising and promotion in order to reduce health and social problems. However, under current and pending international agreements, negotiated by trade experts without public health input, governments and corporations may challenge these protections as constraints on trade. Advocates must recognise the inherent conflicts between free trade and public health and work to exclude alcohol and tobacco from trade agreements. The Framework Convention on Tobacco Control has potential to protect tobacco policies and serve as a model for alcohol control.

  3. Internal Targeting and External Control: Phototriggered Targeting in Nanomedicine.

    Arrue, Lily; Ratjen, Lars

    2017-12-07

    The photochemical control of structure and reactivity bears great potential for chemistry, biology, and life sciences. A key feature of photochemistry is the spatiotemporal control over secondary events. Well-established applications of photochemistry in medicine are photodynamic therapy (PDT) and photopharmacology (PP). However, although both are highly localizable through the application of light, they lack cell- and tissue-specificity. The combination of nanomaterial-based drug delivery and targeting has the potential to overcome limitations for many established therapy concepts. Even more privileged seems the merger of nanomedicine and cell-specific targeting (internal targeting) controlled by light (external control), as it can potentially be applied to many different areas of medicine and pharmaceutical research, including the aforementioned PDT and PP. In this review a survey of the interface of photochemistry, medicine and targeted drug delivery is given, especially focusing on phototriggered targeting in nanomedicine. © 2017 Wiley-VCH Verlag GmbH & Co.

    2015-03-01

    Full Text Available This study analyzes how Management Accounting and Control Systems (MACS facilitate the appropriation of the benefits of sustainable innovations in organizations. In particular, this paper examines the moderating role of different types of MACS in the relationships between sustainable innovation and international performance at an organizational level. We collected survey data from 123 Spanish and Portuguese organizations. Partial Least Square was used to analyze the data. Results show that the effect of sustainable innovations on international performance is enhanced by contemporary rather than traditional types of MACS. Overall our findings show that MACS can help managers to develop and monitor organizational activities (e.g., costumer services and distribution activities, which support the appropriation of the potential benefits from sustainable innovation. This paper responds to recent calls for in-depth studies about the organizational mechanism that may enhance the success of sustainable innovation.

  13. Controlling pandemic flu: the value of international air travel restrictions.

    Directory of Open Access Journals (Sweden)

    Joshua M Epstein

    2007-05-01

    Full Text Available Planning for a possible influenza pandemic is an extremely high priority, as social and economic effects of an unmitigated pandemic would be devastating. Mathematical models can be used to explore different scenarios and provide insight into potential costs, benefits, and effectiveness of prevention and control strategies under consideration.A stochastic, equation-based epidemic model is used to study global transmission of pandemic flu, including the effects of travel restrictions and vaccination. Economic costs of intervention are also considered. The distribution of First Passage Times (FPT to the United States and the numbers of infected persons in metropolitan areas worldwide are studied assuming various times and locations of the initial outbreak. International air travel restrictions alone provide a small delay in FPT to the U.S. When other containment measures are applied at the source in conjunction with travel restrictions, delays could be much longer. If in addition, control measures are instituted worldwide, there is a significant reduction in cases worldwide and specifically in the U.S. However, if travel restrictions are not combined with other measures, local epidemic severity may increase, because restriction-induced delays can push local outbreaks into high epidemic season. The per annum cost to the U.S. economy of international and major domestic air passenger travel restrictions is minimal: on the order of 0.8% of Gross National Product.International air travel restrictions may provide a small but important delay in the spread of a pandemic, especially if other disease control measures are implemented during the afforded time. However, if other measures are not instituted, delays may worsen regional epidemics by pushing the outbreak into high epidemic season. This important interaction between policy and seasonality is only evident with a global-scale model. Since the benefit of travel restrictions can be substantial while

    This paper addresses the trajectory control problem of an underwater inspection robot for nuclear reactor internals. From the viewpoint of control engineering, the trajectory control of the underwater robot is a difficult task due to its nonlinear dynamics, which includes various hydraulic forces such as buoyancy and hydrodynamic damping, the difference between the centres of gravity and buoyancy, and disturbances from a tether cable. To solve such problems, we applied Time Delay Control to the underwater robot. This control law has a very simple structure not requiring nonlinear plant dynamics, and was proven to be highly robust against nonlinearities, uncertainties and disturbances. We confirmed its effectiveness through experiments.

    Wilson, Mark E.; Cole, Harold E.; Rector, Tony; Steele, John; Varsik, Jerry

    2011-01-01

    The Internal Active Thermal Control System (IATCS) aboard the International Space Station (ISS) is primarily responsible for the removal of heat loads from payload and system racks. The IATCS is a water based system which works in conjunction with the EATCS (External ATCS), an ammonia based system, which are interfaced through a heat exchanger to facilitate heat transfer. On-orbit issues associated with the aqueous coolant chemistry began to occur with unexpected increases in CO2 levels in the cabin. This caused an increase in total inorganic carbon (TIC), a reduction in coolant pH, increased corrosion, and precipitation of nickel phosphate. These chemical changes were also accompanied by the growth of heterotrophic bacteria that increased risk to the system and could potentially impact crew health and safety. Studies were conducted to select a biocide to control microbial growth in the system based on requirements for disinfection at low chemical concentration (effectiveness), solubility and stability, material compatibility, low toxicity to humans, compatibility with vehicle environmental control and life support systems (ECLSS), ease of application, rapid on-orbit measurement, and removal capability. Based on these requirements, ortho-phthalaldehyde (OPA), an aromatic dialdehyde compound, was selected for qualification testing. This paper presents the OPA qualification test results, development of hardware and methodology to safely apply OPA to the system, development of a means to remove OPA, development of a rapid colorimetric test for measurement of OPA, and the OPA on-orbit performance for controlling the growth of microorganisms in the ISS IATCS since November 3, 2007.

    2012-12-01

    Full Text Available Through the hereby study we set ourselves on an analysis over the internal control and the ways of implementation of it. The final purpose of our research is represented by the characteristics of the internal control system in the context of current accountancy regulations. The accomplishment of such goal has forced us to research the current literature in the area and also the legal regulations over internal control. Of course, the accomplishment of such a research was possible only after a pertinent analysis over the opinions expressed in specialty literature regarding this area. Our research wants to be with a theoretical and applicative character. It is based on analysing the internal control system, the methodology of internal control and the steps of internal control. We express our belief that the implementation of the internal control in a very exact manner comes as an aid to the company management and lead to the accomplishment of managerial objectives and policies. In what it regards the result of our research there can be drawn the following conclusions: from the legal regulations (OMFP nr. 3055/2009, there is no clear conclusion over the procedures and policies of implementation of internal control applicable to an economical entity; also there are not presented in a detailed way the types (forms of internal control, being presented in the legal regulations only a classification of them after the time in which they are exercised (before, during or after the finishing of the operations; also in the legal regulations there is developed a certain way of internal control, represented by the financial and accounting internal control, as if the other forms of internal control do not exist; in what regards the components of internal control, these are presented in another way, but similar to already known models of internal control (Coso and Coco; also in the legal regulations there are presented the general objectives of internal control

  8. Controlled Vocabularies Boost International Participation and Normalization of Searches

    The Global Change Master Directory's (GCMD) science staff set out to document Earth science data and provide a mechanism for it's discovery in fulfillment of a commitment to NASA's Earth Science progam and to the Committee on Earth Observation Satellites' (CEOS) International Directory Network (IDN.) At the time, whether to offer a controlled vocabulary search or a free-text search was resolved with a decision to support both. The feedback from the user community indicated that being asked to independently determine the appropriate 'English" words through a free-text search would be very difficult. The preference was to be 'prompted' for relevant keywords through the use of a hierarchy of well-designed science keywords. The controlled keywords serve to 'normalize' the search through knowledgeable input by metadata providers. Earth science keyword taxonomies were developed, rules for additions, deletions, and modifications were created. Secondary sets of controlled vocabularies for related descriptors such as projects, data centers, instruments, platforms, related data set link types, and locations, along with free-text searches assist users in further refining their search results. Through this robust 'search and refine' capability in the GCMD users are directed to the data and services they seek. The next step in guiding users more directly to the resources they desire is to build a 'reasoning' capability for search through the use of ontologies. Incorporating twelve sets of Earth science keyword taxonomies has boosted the GCMD S ability to help users define and more directly retrieve data of choice.

    It is shown that, since the early 1970s, the market prices of all energy sources have been regulated by the market value of crude oil at the international level, which in turn depends upon the magnitude of individual value of production units located within the least productive oilfields of the continental USA. Thus, historically and methodologically, the globalization of the petroleum industry together with the preponderant influence of US oil capital over other energy sources, especially its control over US coal, can be considered as, first of all, the fundamental basis of an all-embracing energy industry consisting of all sources and, second, the driving force behind the internationalization of capital in the energy industry.

    Roman, Monsi C.; Wieland, Paul O.

    2005-01-01

    Since January 1999, the chemical the International Space Station Thermal Control System (IATCS) and microbial state of (ISS) Internal Active fluid has been monitored by analysis of samples returned to Earth. Key chemical parameters have changed over time, including a drop in pH from the specified 9.5 +/- 0.5 ta = 58.4, an increase in the level of total inorganic carbon (TIC), total organic carbon (TOC) and dissolved nickel (Ni) in the fluid, and a decrease in the phosphate (PO,) level. In addition, silver (AS) ion levels in the fluid decreased rapidly as Ag deposited on internal metallic surfaces of the system. The lack of available Ag ions coupled with changes in the fluid chemistry has resulted in a favorable environment for microbial growth. Counts of heterotrophic bacteria have increased from less than 10 colony-forming units (CFUs)/l00 mL to l0(exp 6) to l0(exp 7) CFUs/100 mL. The increase of the microbial population is of concern because uncontrolled microbiological growth in the IATCS can contribute to deterioration in the performance of critical components within the system and potentially impact human health if opportunistic pathogens become established and escape into the cabin atmosphere. Micro-organisms can potentially degrade the coolant chemistry; attach to surfaces and form biofilms; lead to biofouling of filters, tubing, and pumps; decrease flow rates; reduce heat transfer; initiate and accelerate corrosion; and enhance mineral scale formation. The micro- biological data from the ISS IATCS fluid, and approaches to addressing the concerns, are summarized in this paper.

    Current profile tailoring has been performed by application of electron cyclotron heating (ECH) and electron cyclotron current drive, leading to improved energy confinement in the plasma core of the TCV tokamak. The improved confinement is characterized by a substantial enhancement (H-factor) of the global electron energy confinement time relative to the prediction of the RLW scaling law (Rebut P H et al 1989 Proc. 12th Int. Conf. of Plasma Physics and Controlled Fusion Research (Nice, 1988) vol 2 (Vienna: IAEA) p 191), which predicts well Ohmic and standard ECH discharges on TCV. The improved confinement is attributed to a hollow current density profile producing a reversed shear profile creating an electron internal transport barrier. We relate the strength of the barrier to the depth of the hollow current density profile and the volume enclosed by the radial location of the peak current density. The ρ T * (Tresset G et al 2002 Nucl. Fusion 42 520) criterion is used to evaluate the performance of the barrier relative to changes in the ECH parameters or the addition of Ohmic current, which aid in identifying the control parameters available for improving either the strength or volume of the barrier for enhanced performance. A figure of merit for the global scaling factor is used that scales the confinement enhancement as the product of the barrier volume and strength

    Depression and anxiety are prevalent and impairing forms of psychopathology in children and adolescents. Deficits in early executive control (EC) may contribute to the development of these problems, but longitudinal studies with rigorous measurement across key developmental periods are limited. The current study examines EC in preschool as a predictor of subsequent depression and anxiety symptoms in elementary school in a community sample (N = 280). Child participants completed a battery of nine developmentally-appropriate tasks designed to measure major aspects of EC at age 5 years, 3 months. Children later participated in an elementary school follow-up phase, during which they completed validated norm-referenced self-report questionnaires of depression and anxiety symptoms in fourth grade. Results indicate that poorer preschool EC was significantly associated with both greater depression and anxiety symptoms in elementary school, controlling for baseline depression and anxiety symptoms in preschool and other relevant variables. These findings suggest that poor EC may be an important risk factor for the development of internalizing psychopathology in childhood. Given emerging evidence for the modifiability of EC, particularly in preschool, EC promotion interventions may hold promise as a potential target in psychopathology prevention.

The dependence between the effectiveness of accounting and internal control of a budget institution is determined. The paper highlights the methods of evaluation of internal control of a budget institution. This method is recommended for use in the preliminary assessment of control risk budget institution. The concept of «decision» as on the whole and also in particular in internal control is covered. The essential grouping indications of internal control decisions are defined and every type of decisions is characterized. The main directions of improvement of internal control to prevent violations in accounting of a budgetary institution is examined.

  6. Shared internal models for feedforward and feedback control.

    A child often learns to ride a bicycle in the driveway, free of unforeseen obstacles. Yet when she first rides in the street, we hope that if a car suddenly pulls out in front of her, she will combine her innate goal of avoiding an accident with her learned knowledge of the bicycle, and steer away or brake. In general, when we train to perform a new motor task, our learning is most robust if it updates the rules of online error correction to reflect the rules and goals of the new task. Here we provide direct evidence that, after a new feedforward motor adaptation, motor feedback responses to unanticipated errors become precisely task appropriate, even when such errors were never experienced during training. To study this ability, we asked how, if at all, do online responses to occasional, unanticipated force pulses during reaching arm movements change after adapting to altered arm dynamics? Specifically, do they change in a task-appropriate manner? In our task, subjects learned novel velocity-dependent dynamics. However, occasional force-pulse perturbations produced unanticipated changes in velocity. Therefore, after adaptation, task-appropriate responses to unanticipated pulses should compensate corresponding changes in velocity-dependent dynamics. We found that after adaptation, pulse responses precisely compensated these changes, although they were never trained to do so. These results provide evidence for a smart feedback controller which automatically produces responses specific to the learned dynamics of the current task. To accomplish this, the neural processes underlying feedback control must (1) be capable of accurate real-time state prediction for velocity via a forward model and (2) have access to recently learned changes in internal models of limb dynamics.

    Full Text Available Public preschool educational institutions in Slovenia are mostly financed by public money, it means bay state and municipalities. They are also financed by parents. So, it is important that preschool institutions are using public money transparent and responsible, for this reason public preschool institution should have internal controls in financing. The internal auditor as independent professional should verify if internal controls works. The purpose of this paper is to investigate how internal controls in financing public educational institution works it means which internal controls are important in financing the preschool institution - on the selected institution to show and check how internal controls work. For this reason we divide internal controls in the financing in two phases: (1 internal controls in the preparation of the annual financial plan and financial planning of financial resources for institution’s programs and activities, (2 internal controls in obtaining financial resources. We used methods of internal auditing and research approaches as sampling, unstructured interviews and analysis of documents. The results showed that selected preschool institution should work on rules of recovery and monitoring of claims. The findings provide useful academic insight to setting internal controls as well as practical guidance for preschool institutions.

    Some issues of control in complex dynamical systems are considered. The authors discuss two control mechanisms, namely: a short range, reactive control based on the chaos control idea and a long-term strategic control based on an optimal control algorithm. They apply these control ideas to simple examples in a discrete nonlinear model of a multi-nation arms race.

  9. Controlling a hurricane by altering its internal climate

    Atmospheric hazards, like the fury of a hurricane, can be controlled by altering its internal climate. The hurricane controlling technique suggested is eco-friendly, compatible with hurricane size, has a sound scientific base and is practically possible. The key factor is a large scale dilution of the hurricane fuel, vapour, in the eye wall and spiral rain bands where condensation causing vapor volume reduction (a new concept which can be explained by Avogadro's law) and latent heat release drive the storm. This can be achieved by installing multiple storage tanks containing dry liquefied air on the onshore and offshore coastal regions and islands, preferably underground, in the usual path of a hurricane. Each storage tank is designed to hold and release dry liquefied air of around 100,000 tons. Satellite tracking of hurricanes can locate the eye wall and the spiral rain bands. The installed storage tanks coming under these areas will rapidly inject dry air in huge quantities thereby diluting the vapour content of the vapour-rich air in the eye wall and in the spiral rain bands. This will result in reduced natural input of vapour-rich air, reduced release of latent heat, reduced formation of the low pressure zone due to condensation and volume reduction of the vapor, expansion of the artificially introduced dry air as it goes up occupying a larger space with the diluted fuel, absorption of energy from the system by low temperature of the artificially introduced air. It will effect considerable condensation of the vapor near the sea surface thus further starving the hurricane of its fuel in its engine. Seeding materials, or microscopic dust as suggested by Dr. Daniel Rosenfeld in large quantities may also be introduced via the flow of the injected dry air in order to enhance the hurricane controlling ability. All the above factors are in favour of retarding the hurricane's wind speed and power. The sudden weakening of hurricane Lili was found to be partially caused

    Over the past few decades, the importance of economic research in advancing tobacco control policies has become increasingly clear. Extensive research has demonstrated that increasing tobacco taxes and prices is the single most cost-effective tobacco control measure. The research contained in this supplement adds to this evidence and provides new insights into how smokers respond to tax and price changes using the rich data on purchase behaviours, brand choices, tax avoidance and evasion, and tobacco use collected systematically and consistently across countries and over time by the International Tobacco Control (ITC) Project. The findings from this research will help inform policymakers, public health professionals, advocates, and others seeking to maximise the public health and economic benefits from higher taxes.

  12. Internal quality control in point-of-care testing: where's the evidence?

    Science.gov (United States)

    Holt, Helen; Freedman, Danielle B

    2016-03-01

    ISO 22870 standards require protocols for performance of internal quality control for all point-of-care testing devices and training of users in its theory and practice. However, the unique setting of point-of-care testing (i.e. processes conducted by non-scientific users) means that laboratory internal quality control programmes do not easily translate to point-of-care testing. In addition, while the evidence base for internal quality control within the laboratory has been increasing, the equivalent literature surrounding point-of-care testing is very limited. This has led to wide variation in what is considered acceptable practice for internal quality control at the point of care. Indeed, it has been demonstrated that internal quality control is an area of deficiency in point-of-care testing. Internal quality control protocols used at point-of-care testing should be defined based on risk management. The protocol will therefore be dependent on analyser complexity and availability of inbuilt system checks, the risk associated with release of an incorrect patient result as well as frequency of use. The emphasis should be on designing an effective internal quality control protocol as opposed to the inherent tendency of introducing high-frequency quality control. Typically a simple pass or fail criterion is used for internal quality control in point-of-care testing based on whether internal quality control results fall within assigned ranges. While simply taught, such criteria can require broad internal quality control ranges to decrease the probability of false rejection (also reducing the probability of error detection). Customized internal quality control ranges, two-tier acceptance systems and assay-specific internal quality control can be used to improve error detection rates. © The Author(s) 2016.

    To examine Korean public opinions toward alcohol control measures on availability, advertisement, drink-driving and pricing policy, and how the views on alcohol control policy vary by demographics, drinking patterns and attitude to drinking environments. The study used national-based, cross-sectional data collected in 2012 as part of the International Alcohol Control study. 2510 people (M: 1163, F: 1261) aged 15-65 and living in geographically diverse regions of Korea completed the questionnaire asking the support of 12 alcohol control measures. Generally, targeted measures (purchase age of 20 and drink-driving) were more popular than universal (availability, advertisement and price) among Koreans. Gender, age, marital status, drinking patterns and attitude to drinking environments related to alcohol use of young and heavy drinkers were strong predictors of the opinions on most of the alcohol control measures. It was daily/weekly drinkers who opposed most restrictions on alcohol availability and price and the support from individuals who are more aware of problems with drinking in public place was outstanding in every control measure. These findings should be taken into account by Korean policy-makers as they formulate an alcohol policy for the country. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  2. Effect of internal controls on credit risk among listed Spanish banks

    Directory of Open Access Journals (Sweden)

    Ellis Kofi Akwaa-Sekyi

    2016-02-01

    Full Text Available Purpose: The paper examines the effectiveness of internal control systems, explores the exposure of Spanish banks to the dangers of default as a result of internal control systems and establishes a relationship between internal controls and credit risk. Design/Methodology/Approach: Quantitative research approach is used to test hypotheses on the relationship between internal controls and credit risk among listed banks in Spain. Data from Bankscope and company websites from 2004-2013 were used. Generalized Least Squares (random effect econometric estimation technique was used for the model. Findings: We find that internal control systems are in place but their effectiveness cannot be guaranteed. This exposes Spanish listed banks to serious default situations. There is significant effect of internal controls on credit risk especially the control environment, risk management, control activities and monitoring. The non-disclosure of material internal control weakness is a contributory factor to the ineffective internal control systems. There is however a perceived board ineffectiveness which does not augur well for effective internal control systems. Board characteristics for Spanish banks confirm the agency theory. Research Limitations and Implications: Data unavailability for certain years, variables and many inactive banks did not permit a larger sample size than expected. The use of quantitative variables lacks flexibility. Practical Implications: Bank management will find the work useful to ensure strict enforcement of internal control mechanisms and see it as both credit risk and operational risk issues.

    1981-09-01

    It became evident in two patients during cerebral angiography that ligation of an internal carotid artery would probably be necessary in the course of a subsequent neurosurgical operation. A balloon catheter was inserted and the internal carotid artery was occluded. A continous EEG recording was made with a Fourier transformed frequency analysis before and during the occlusion; the motor functions of the corresponding side of the body were observed simultaneously on the conscious patient. EEG alterations indicative of cerebral ischemia were not demonstrated in either patient during an occlusion period of 7 min. Unilateral neurosurgical ligation of the common carotid artery and the internal carotid artery was performed on one patient. As predicted no neurological deficit occured.

  17. Control of Modular Multilevel Converter with reduced internal data exchange

    Modular Multilevel Converters (MMC) are penetrating due to their superior performances. Due to the modular structure of the converter, communication platform has to be established between the Sub-Modules (SM) and a Central Controller Unit (CCU). When the communication platform is designed...... for such an application, several key parameters have to be considered such as high speed data transfer with low propagation delay, data integrity, and ability for accurate synchronization. In order to minimize the data flow in the MMC a hierarchical control is proposed where a CCU calculates an identical reference...... for all the SMs while the modulation and capacitor voltage balancing is performed in the controller from the SM. Thus, at each sampling instance only four bytes references are sent by the central controller to the controllers from the SM, while one or two bytes are received from SMs. Further, the control...

  18. Internal Diffusion-Controlled Enzyme Reaction: The Acetylcholinesterase Kinetics.

    Science.gov (United States)

    Lee, Sangyun; Kim, Ji-Hyun; Lee, Sangyoub

    2012-02-14

    Acetylcholinesterase is an enzyme with a very high turnover rate; it quenches the neurotransmitter, acetylcholine, at the synapse. We have investigated the kinetics of the enzyme reaction by calculating the diffusion rate of the substrate molecule along an active site channel inside the enzyme from atomic-level molecular dynamics simulations. In contrast to the previous works, we have found that the internal substrate diffusion is the determinant of the acetylcholinesterase kinetics in the low substrate concentration limit. Our estimate of the overall bimolecular reaction rate constant for the enzyme is in good agreement with the experimental data. In addition, the present calculation provides a reasonable explanation for the effects of the ionic strength of solution and the mutation of surface residues of the enzyme. The study suggests that internal diffusion of the substrate could be a key factor in understanding the kinetics of enzymes of similar characteristics.

    1987-01-01

    Contamination inside Space Station modules was studied to determine the best methods of controlling contamination. The work was conducted in five tasks that identified existing contamination control requirements, analyzed contamination levels, developed outgassing specification for materials, wrote a contamination control plan, and evaluated current materials of offgassing tests used by NASA. It is concluded that current contamination control methods can be made to function on the Space Station for up to 1000 days, but that current methods are deficient for periods longer than about 1000 days.

    International Nuclear Information System (INIS)

    Kim, H.; Bankoff, S.G.; Miksis, M.J.

    1991-01-01

    An electrostatic liquid film space radiator is proposed. This will employ an internal electrostatic field to prevent leakage of the liquid-metal coolant out of a puncture. This overcomes the major disadvantage of membrane radiators, which is their vulnerability to micrometeorite impacts. Calculations show that leaks of liquid lithium at 700 degree K can easily be stopped from punctures which are several mm in diameter, with very large safety factors. The basic idea lends itself to a variety of radiator concepts, both rotating and non-rotating. Some typical film thickness and pressure calculations in the presence of an electric field are shown

  6. Arms Control: US and International efforts to ban biological weapons

    Energy Technology Data Exchange (ETDEWEB)

    1992-12-01

    The Bacteriological (Biological) and Toxin Weapons Convention, the treaty that bans the development, production, and stockpiling and acquisition of biological weapons was opened for signature in 1972 and came into force in 1975 after being ratified by 22 governments, including the depository nations of the USA, the United Kingdom, and the former Soviet Union. In support of the Convention, the USA later established export controls on items used to make biological weapons. Further, in accordance with the 1990 President`s Enhanced Proliferation Control Initiative, actions were taken to redefine and expand US export controls, as well as to encourage multilateral controls through the Australia Group. Thus far, the Convention has not been effective in stopping the development of biological weapons. The principal findings as to the reasons of the failures of the Convention are found to be: the Convention lacks universality, compliance measures are effective, advantage of verification may outweigh disadvantages. Recommendations for mitigating these failures are outlined in this report.

Results: In modern conditions high-quality products are necessity-term, but not sufficient to achieve the successful operation of the market. To optimize the above goal should be to work out issues such as the definition of the requirements of potential customers, the timing, location and conditions of the transaction, that is, the seller must offer the buyer at a particular moment only the product that the best way to satisfy existing need for the latter. This may explain the reason for the proposed buyers of high-quality goods are distributed in the market of one country and cannot find it in another. Discussion: The information presented in this article marketing management model allows you to organize all marketing activities and events, and do them not by chance, but in the complex, taking into account their relationship and interaction. As well as the opportunity to working with mesh product and market development to identify new attraction activities and evaluate them in terms of compliance with the overall objectives and company resources. In addition, the proposed method of assessing the effectiveness of a marketing system is universal, and it allows you to analyze the effectiveness of the functioning of the marketing of individual enterprises, regardless of scope, given the impact of all factors.

    International Nuclear Information System (INIS)

    Furuta, Katsuhisa; Kosuge, Kazuhiro; Shiote, Yoshinori; Hatano, Hiromu.

    1988-01-01

    This paper presents an alternative control architecture of master-slave manipulators based on the concept of virtual internal model following control. The proposed control architecture realizes the master-salve manipulator system with functions which assist operators based on the external information from sensors as well as bilateral feedback. In this paper, the control problem of a master-slave manipulator is formulated as the realization problem of the desired relation between a master arm and a slave arm. The virtual internal model, whose input includes the external sensory information, is used to describe the desired relation. The control system is designed so that the master arm and the slave arm tracks the desired trajectories generated by the virtual internal model. The proposed control architecture is experimentally applied to the master-slave manipulator system with force sensors and the effectiveness of the control architecture is illustrated through experiments.

    Shea, T.

    1997-01-01

    The elimination of nuclear weapons will require success in three interrelated efforts: stopping the proliferation of nuclear weapons by states through indigenous programs; preventing the illicit acquisition o warheads, components or essential materials by states, sub-national organizations or individuals; and halting further production and eliminating existing nuclear weapons in acknowledged nuclear-weapon-states and in other states that may now possess such weapons. The elimination of nuclear weapons is a challenge for regional and global security and perhaps more than any other security issue, a matter of most appropriate for collective control measures. The most significant issues concerning control are related to proliferation and peaceful uses of plutonium and highly enriched uranium. The IAEA has a special role, tasks and responsibilities concerning verification of non-proliferation, plutonium management, illegal trafficking of plutonium and/or highly enriched uranium, production cut-off of fissile material

  1. Planar reorientation maneuvers of space multibody systems using internal controls

    Science.gov (United States)

    Reyhanoglu, Mahmut; Mcclamroch, N. H.

    1992-01-01

    In this paper a reorientation maneuvering strategy for an interconnection of planar rigid bodies in space is developed. It is assumed that there are no exogeneous torques, and torques generated by joint motors are used as means of control so that the total angular momentum of the multibody system is a constant, assumed to be zero in this paper. The maneuver strategy uses the nonintegrability of the expression for the angular momentum. We demonstrate that large-angle maneuvers can be designed to achieve an arbitrary reorientation of the multibody system with respect to an inertial frame. The theoretical background for carrying out the required maneuvers is briefly summarized. Specifications and computer simulations of a specific reorientation maneuver, and the corresponding control strategies, are described.

    Bone and cartilage generation by three-dimensional scaffolds is one of the promising techniques in tissue engineering. One approach is to generate histologically and functionally normal tissue by delivering healthy cells in biocompatible scaffolds. These scaffolds provide the necessary support for cells to proliferate and maintain their differentiated function, and their architecture defines the ultimate shape. Rapid prototyping (RP) is a technology by which a complex 3-dimensional (3D) structure can be produced indirectly from computer aided design (CAD). The present study aims at developing a 3D organic-inorganic composite scaffold with defined internal architecture by a RP method utilizing a 3D printer to produce wax molds. The composite scaffolds consisting of chitosan and hydroxyapatite were prepared using soluble wax molds. The behaviour and response of MC3T3-E1 pre-osteoblast cells on the scaffolds was studied. During a culture period of two and three weeks, cell proliferation and in-growth were observed by phase contrast light microscopy, histological staining and electron microscopy. The Giemsa and Gömöri staining of the cells cultured on scaffolds showed that the cells proliferated not only on the surface, but also filled the micro pores of the scaffolds and produced extracellular matrix within the pores. The electron micrographs showed that the cells covering the surface of the struts were flattened and grew from the periphery into the middle region of the pores.

    Burnout is a major problem for nursing. There is a strong relationship between work stress and emotional exhaustion. Although studies report a negative correlation between the internal locus of control and emotional exhaustion and work stress, the number of studies available on the subject is limited. This study intends to examine the extent to which the relationship between work stress and emotional exhaustion is mediated by nurses' internal locus of control. The study adopted a cross-sectional survey design. The data were analyzed using structural equation modeling techniques. The study sample consisted of 347 nurses who worked in a university hospital in Izmir, Turkey and who agreed to participate in the study. The Work-Related Strain Inventory was used to evaluate the nurses' work stress level, Maslach Burnout Inventory was used to evaluate their emotional exhaustion levels, and the Locus of Control Scale was used to evaluate the internal locus of control. The variables of the study were based on the Neuman Systems Model. Work stress was positively related to internal locus of control (β3 = .21, p 0.1). Internal locus of control was negatively related to emotional exhaustion (β = -.14, p Work stress is directly (β = .87, p Work stress is directly (β = .87, p work stress was mediated, the impact of internal locus of control was limited. It is recommended that different variables be included in future studies so that they can mediate the relationship between work stress and emotional exhaustion.

    Warner, Kenneth E

    2015-07-09

    Despite their lethality, cigarettes are subject to little regulation that directly restricts their contents or their legality. This may change in the near future with the Framework Convention on Tobacco Control (FCTC), the world's first global health treaty, now in force, as well as developments in a few individual countries. Cigarettes are subject to a substantial number of country-specific regulations regarding their conditions of sale: their price (mostly through taxation), the places where they can be consumed (clean indoor air laws), who can smoke them (prohibitions on their use by or sales to minors), how they can be advertised or promoted (if at all), and how they must be packaged (minimum pack sizes, warning labels, plain packaging). Such policies constitute the core of successful tobacco control. The FCTC has been ratified by 180 countries representing 90% of the world's population. The FCTC requires compliance with numerous provisions relating to the kinds of regulations noted above. The treaty also mandates explicit attention to direct product regulation. Several countries have such authority, at least in limited forms. In the US, for example, the Food and Drug Administration (FDA) now has the legal authority to regulate tobacco products, including their contents. The possibility exists that, in the foreseeable future, a country will mandate product standards that will substantially reduce the appeal of cigarettes and other combusted tobacco products, which are by far the leading sources of the death and disease associated with tobacco.

  1. Review of selected dynamic material control functions for international safeguards

    Lowry, L.L.

    1980-09-01

    With the development of Dynamic Special Nuclear Material Accounting and Control systems used in nuclear manufacturing and reprocessing plants, there arises the question as to how these systems affect the IAEA inspection capabilities. The systems in being and under development provide information and control for a variety of purposes important to the plant operator, the safeguards purpose being one of them. This report attempts to judge the usefulness of these dynamic systems to the IAEA and have defined 12 functions that provide essential information to it. If the information acquired by these dynamic systems is to be useful to the IAEA, the inspectors must be able to independently verify it. Some suggestions are made as to how this might be done. But, even if it should not be possible to verify all the data, the availability to the IAEA of detailed, simultaneous, and plant-wide information would tend to inhibit a plant operator from attempting to generate a floating or fictitious inventory. Suggestions are made that might be helpful in the design of future software systems, an area which has proved to be fatally deficient in some systems and difficult in all

    Research has neglected the potential role of perceived parental control as a moderator between stressful life events (SLEs) and child internalizing symptoms. Using secondary data from the Early Risers “Skills for Success” Program, this study examined the impact of perceived parental control on the association between SLEs and child internalizing symptoms in formerly homeless families. The sample consisted of 137 families with 223 children between 4 and 12 years of age (M = 8.1, SD = 2.3) living in supportive housing sites in Minneapolis, Minnesota. Participants completed measures assessing the number of SLEs experienced (e.g., unemployment of parent, death of loved one, serious illness, homelessness, etc.), perceived parental control, and child internalizing symptoms. In this sample, 65% of children (n = 144) experienced at least one SLE with an average experience of two events (M = 2.0, SD = 1.9, Range: 0–7 SLEs). A regression analysis found that experiencing more SLEs and a perceived absence of parental control over child behavior were positively associated with child internalizing symptoms. A significant interaction between SLEs and perceived absence of parental control over child behavior in predicting child internalizing symptoms was also found. These findings suggest that children of parents who model appropriate control are more likely to experience fewer internalizing symptoms in response to SLEs. PMID:27991820

    Full Text Available Objective – The presence of Small Medium Enterprises (SMEs has been able to be livelihoods sources and absorb more labor, even though it has a relative smaller contribution of additional value compared to the Large-scale Enterprises. The number of economic actors of SMEs spread across area from urban to rural. However, SMEs have faced several serious problems. These problems are caused by the unique characteristics of SMEs itself. First, lack of managerial skills due to limited human resources and lack of monitoring which it is rarely conducted by the manager or the owner. Second, lack of information and technology to carry out operations. Both problems have great impacts in lack of internal controls. Third, SMEs also face problems in developing business scale, limited access to capital to the banks and financial institutions due to the lack of transparency. Therefore, this research aimed to detect to what extent of the problems arising in the application and assessment of internal controls performed by SMEs.Method – The research employs descriptive qualitative research method through direct observation, interview and business documentation owned by the company. Research materials are 29 SMEs consisting of 19 trading SMEs and 10 service SMEs. All SMEs are located in Malang city. Detection of application and assessment of internal controls in this study is based on the COSO framework and the Islamic perspective.Result – Internal control activities indicators apply the five principles of COSO framework which focused on three layers. First layer is self-assessment control area. Second layer is environment control area and the third layer is independent control area. While the Islamic perspective is focused on the internal control of business activities based on the Qur'an and Hadith. The results derive from application and assessment based on COSO framework and Islamic perspectives are complementary in improving the practice of internal

  5. The double meaning of control: three-way interactions between internal resources, job control, and stressors at work.

    2008-07-01

    The Job Demand-Control model postulates that job control attenuates the effects of job demands on health and well-being. Support for this interactive effect is rather weak. Conceivably, it holds only when there is a match between job control and individual characteristics that relate to exercising control options, such as locus of control, or self-efficacy. This three-way interaction was tested in a sample of 96 service employees, with affective strain and musculoskeletal pain as dependent variables. As hypothesized, job control attenuated the effects of stressors only for people with an internal locus of control. For people with an external locus of control, job control actually predicted poorer well-being and health as stressors increased. For self-efficacy, the corresponding three-way interaction was significant with regard to affective strain. Copyright (c) 2008 APA, all rights reserved.

    Full Text Available The article substantiates the necessity of organization of internal audit of receivables and accounts payable at the trade enterprises, which will allow the decision-makers to obtain confirmation of the validity of the accountance data. The theoretical substantiation of bases of monitoring together with necessity of its carrying out in the accountance system of accounts receivable and accounts payable was considered. The scheme on interaction of subjects of control has been proposed, in terms of which each of the examined subjects of control is in constant information interaction with other divisions. To effectively control the movement of debt, trade organizations are encouraged to use the forms of operational reporting developed as part of improving internal audit as a tool to enhance the efficiency of the internal control system.

Incorporating COSO principles in the beneficiary’s internal control systems may provide some warranties about compliance to the above mentioned principle as described in the EC Regulation 1605-2002. This study aims to explore some facts in actual internal control environment, as a base for future improvements of Romanian ESF beneficiary’s internal control systems ESF financed interventions covers a large range of costs for implementing labor market related services. But supporting costs according to the sound financial management principle calls for best value for money in real and legal operations. Without some specifics from the donor or a mutual accepted best practice model, most of the ESF beneficiaries are reporting their efforts to actual researches and specialized literature regarding internal control system implementation in services. This study was realized in April 2012 by applying an investigation instrument, an on-line questionnaire collecting both opinions and factual data as well to a number of 962 members of a practice community for ESF interventions implementation. This technique was used to test hypotheses regarding the premises existence for a future improvement of the existing internal control system model. 100 members of this community: managers, accountants, auditors financial responsible and other team members answered anonymously, revealing a real concern for internal control, providing as well a different side image for this. Analyzing all stakeholder answers, we may consider that our hypothesis is correct and there is a real need for internal control environment improvements.

    Recombinase polymerase amplification (RPA) is an isothermal nucleic acid amplification technology that provides rapid and robust infectious disease pathogen detection, ideal for point-of-care (POC) diagnostics in disease-prevalent low-resource countries. We have developed and evaluated three duplex RPA assays incorporating competitive internal controls for the detection of leading bacterial meningitis pathogens. Streptococcus pneumoniae, Neisseria meningitidis and Haemophilus influenzae singleplex RPA assays were initially developed and evaluated, demonstrating 100% specificity with limits of detection of 4.1, 8.5 and 3.9 genome copies per reaction, respectively. Each assay was further developed into internally controlled duplex RPA assays via the incorporation of internal amplification control templates. Clinical performance of each internally controlled duplex RPA assay was evaluated by testing 64 archived PCR-positive clinical samples. Compared to real-time PCR, all duplex RPA assays demonstrated 100% diagnostic specificity, with diagnostic sensitivities of 100%, 86.3% and 100% for the S. pneumoniae, N. meningitidis and H. influenzae assays, respectively. This study details the first report of internally controlled duplex RPA assays for the detection of bacterial meningitis pathogens: S. pneumoniae, N. meningitidis and H. influenzae. We have successfully demonstrated the clinical diagnostic utility of each duplex RPA assay, introducing effective diagnostic technology for POC bacterial meningitis identification in disease-prevalent developing countries.

    1977-12-01

    Detailed negotiations over a possible package of measures to reform international safeguards and security managements under which nuclear technology is transferred are going on behind closed doors in the ''London Club,'' or Nuclear Suppliers' Group. The talks appear to be chiefly concentrated on bilateral agreements over national measures of control. The author examines some possible aims and functions that seem reasonable targets for negotiated reform over the coming months. These would include: jointly guaranteed supplies of low-enriched uranium for thermal reactors; a new international safeguards system; international nuclear security and safety standards; international agreement on nuclear waste disposal measures; international institutional initiative to promote alternative energy sources; functional reform of the IAEA; and reorganized regulatory review processes at national levels.

    Full Text Available It is well known that not only in Romania, internal control and auditing are subject to legal regulations. Often, the two forms of ensuring the quality of accounting information are particularly perceived as mandatory requirement instead of as a necessity for certifying the information travelling between producer and user. The paper addresses issues which aim to highlight the need to organize the internal control and auditing of the accounting information from the perspective of the need to certify the accounting information for a responsible reporting. Moreover, through a study conducted on a sample of 301 companies in the Central Region of Romania, we also captured the managers’/directors’ opinion regarding the internal control and audit in terms of confidence, ensuring opportunities to valorise the accounting information and its usefulness for management.

To aid in controlling zoonoses, countermeasures have been strengthened against these diseases and are maintained at both national and international levels. Atypical example of this international effort can be found in the revised International Health Regulations (2005), known as the IHR (2005), which were instituted by the World Health Organization and have been implemented since 2007. In Japan, the appropriate Ministries have established frameworks for controlling zoonoses that employ both administrative and scientific approaches to fulfill the demands of the IHR (2005). In this paper, the authors present the Japanese framework for controlling zoonoses, as a useful example for global public and animal health management in coming years.

    Full Text Available The PIFC /Public Internal Financial Control/ was developed by the European Commission. PIFC is set of principles internal financial controls system established for the purpose of controlling, auditing, supervise on the use of national budget and European Union budget and funds. Also, in order to support candidate countries in their internal control system reforms in the public sector. Therefore, it is expected for the candidate countries to establish and develop the system of internal financial controls according to the concept which was in that field developed by the European Union based on International Standards and the best practice of European countries. Since the year 2003 the Republic of Croatia undertakes intensive activities on the establishment and development of the internal financial control system according with the regulation of European Union. In keeping with the set concept, the Republic of Croatia undertook numerous activities during the past six years to create all the necessary assumptions for the establishment and development of the system, including: the adoption of the initial strategic documents; drafting of laws; the creation of organisational capacities and human resources; and the implementation of the system with budget users at central government and local levels. In this paper we will present phases of implementation PIFC in Croatian Public Sector. Through this phases we will show impact that PIFC has on development of New Public Management in Croatia and changes in organizational structure and human resource that are caused during this process. Also, we will give critical opinion of that process and problems which occur during implementation. In this paper we will present approach in implementation of PIFC in Slovenia and Bosnia and Herzegovina and compare this with implementation in Croatia.

    Control strategies for auto-ignition control in turbocharged internal combustion engines operating with gaseous fuels are presented. Ambient temperature and ambient pressure are considered as the disturbing variables. A thermodynamic model for predicting temperature at the ignition point is developed, adjusted and validated with a large experimental data-set from high power turbocharged engines. Based on this model, the performance of feedback and feedforward auto-ignition control strategies is explored. A robustness and fragility analysis for the Feedback control strategies is presented. The feedforward control strategy showed the best performance however its implementation entails adding a sensor and new control logic. The proposed control strategies and the proposed thermodynamic model are useful tools for increasing the range of application of gaseous fuels with low methane number while ensuring a safe running in internal combustion engines. - Highlights: • A model for predicting temperature at the ignition point. • Robust PID, modified PID, and feedforward strategies for auto-ignition control. • λ′ were the best set of tuning equations for calculating controller parameters. • Robust PID showed significant improvements in auto-ignition control. • Feedforward control showed the best performance

  10. MONITORING IN CREDIT INSTITUTIONS – COMPARATIVE APPROACH ON INTERNAL CONTROL SYSTEMS – THE CASE OF ROMANIA VS. INTERNATIONAL MODELS OF CONTROL

    2010-07-01

    Full Text Available Starting from the stipulations of the two well-known internal control system models – COSO and CoCo - the purpose of this paper is to focus on the Romanian framework for credit institutions – trying to to identify on which international model is our national one most appropriate to. The research methodology is based on an empirical analysis between Romanian regulation and the models already mentioned. To reach to a conclusion we tried to identify several key issues closely related to information and communication, and to determine the degree of similarities and dissimilarities between the three selected frameworks, by using statistical indicators. The paper has some limitations, too, because it only approaches formal harmonization. So, those issues analyzed through the regulations’ perspectives need to be closely quantified in matters of their actual implementation, which offer us outlooks of future research.

    Running is the most important discipline for Olympic triathlon success. However, cycling impairs running muscle recruitment and performance in some highly trained triathletes; though it is not known if this occurs in elite international triathletes. The purpose of this study was to investigate the effect of cycling in two different protocols on running economy and neuromuscular control in elite international triathletes. Muscle recruitment and sagittal plane joint angles of the left lower extremity and running economy were compared between control (no preceding cycle) and transition (preceded by cycling) runs for two different cycle protocols (20-minute low-intensity and 50-minute high-intensity cycles) in seven elite international triathletes. Muscle recruitment and joint angles were not different between control and transition runs for either cycle protocols. Running economy was also not different between control and transition runs for the low-intensity (62.4 +/- 4.5 vs. 62.1 +/- 4.0 ml/min/kg, p > 0.05) and high-intensity (63.4 +/- 3.5 vs. 63.3 +/- 4.3 ml/min/kg, p > 0.05) cycle protocols. The results of this study demonstrate that both low- and high-intensity cycles do not adversely influence neuromuscular control and running economy in elite international triathletes.

    2017-06-01

    Discrimination and inequality shape women's experiences of drug use and in the drug trade and the impact of drug control efforts on them, with disproportionate burdens faced by poor and otherwise marginalized women. In recent years, UN member states and UN drug control and human rights entities have recognized this issue and made commitments to integrate a 'gender perspective' into drug control policies, with 'gender' limited to those conventionally deemed women. But the concept of gender in international law is broader, rooted in socially constructed and culturally determined norms and expectations around gender roles, sex, and sexuality. Also, drug control policies often fail to meaningfully address the specific needs and circumstances of women (inclusively defined), leaving them at risk of recurrent violations of their rights in the context of drugs. This article explores what it means to 'mainstream' this narrower version of gender into drug control efforts, using as examples various women's experiences as people who use drugs, in the drug trade, and in the criminal justice system. It points to international guidelines on human rights and drug control as an important tool to ensure attention to women's rights in drug control policy design and implementation.

  15. Banks’ internal controls and risk management: Value-added functions in Italian credit cooperative banks

    2013-12-01

    Full Text Available A critical component of safe and sound bank management is constituted by an effective and efficient system of internal controls, which help to ensure that the goals and objectives of a bank will be met, that long-term profitability targets will be achieved, and maintain reliable financial and managerial reporting. Such a system can also ensure that the bank will comply with laws and regulations as well as policies, plans, internal rules and procedures, and decrease the risk of unexpected losses or damage to the bank’s reputation. The paper describes the essential elements of a sound internal control system and through a qualitative approach, it shows how is tied to the rules attaining capital requirements and, above all, to the purpose of the Internal Capital Adequacy Assessment Process (ICAAP which aims at determining the adequate capitalisation of a bank given the risks endured as well as future risks arising from growth, and new business lines. After the recent financial crisis ICAAP is becoming more and more relevant and a central component of an effective strategy for managing risk and creating value. All principles and considerations are referred to Italian Credit Cooperative Banks particular both for dimension and for governance and risk management. They have been contacted though local federations and the results confirm the existing of weakness in internal controls.

  16. Parental Negative Control Moderates the Shyness–Emotion Regulation Pathway to School-Age Internalizing Symptoms

    Shaw, Daniel S.; Moilanen, Kristin L.

    2011-01-01

    Models of developmental psychopathology emphasize both mediation and moderation processes among child and caregiving attributes; however, little research has examined both these processes simultaneously on the development of internalizing problems. This study tested a moderated mediation model that related early childhood shyness, emotion regulation and maternal negative control to school-age internalizing problems among 257 boys from low-income families. Shyness and maternal negative control was assessed at ages 1.5–2, emotion regulation was observed at age 3.5, and internalizing symptoms were assessed by mothers and teachers at age 6 or 7. Results indicated that 1) the active distraction regulation strategy mediated the relations between early shyness and maternal report of internalizing symptoms; 2) the passive/dependent regulation strategy mediated the relations between shyness and teacher report of internalizing symptoms; and 3) both mediation processes were moderated by maternal negative control. The results are discussed in relation to implications for early prevention and intervention. PMID:21107676

    2016-06-01

    This investigation addressed the relation between maternal warmth, behavioral control, psychological control, and psychological adjustment in a sample of 119 Ghanaian adolescents (42% boys) living in an urban area (mean age = 14.19). Adolescents in the sample reported clinically elevated levels of depression and anxiety. Significant associations were found between warmth, behavioral control, and psychological control and adolescents' anxiety, physical aggression, relational aggression, positive friendship quality, and conflict with friends. Warmth moderated the effect of behavioral control on anxiety, physical aggression, and relational aggression such that higher levels of warmth in combination with higher levels of behavioral control were related to more positive adjustment. Higher levels of warmth in conjunction with higher psychological control were related to higher levels of anxiety. Boys who reported lower levels of warmth in combination with higher behavioral control reported higher levels of physical aggression. For boys reporting higher levels of warmth, higher behavioral control was associated with lower physical aggression. Copyright © 2016 The Foundation for Professionals in Services for Adolescents.

    . The complexity of the external and semi-internal amplification controls must be comparable with the assumed complexity of the samples. We also emphasize that amplification controls should be applied in multi-template PCR regardless of the post-assay method used to analyze products.......In a mixed template, the presence of homologous target DNA sequences creates environments that almost inevitably give rise to artifacts and biases during PCR. Heteroduplexes, chimeras, and skewed template-to-product ratios are the exclusive attributes of mixed template PCR and never occur...... in a single template assay. Yet, multi-template PCR has been used without appropriate attention to quality control and assay validation, in spite of the fact that such practice diminishes the reliability of results. External and internal amplification controls became obligatory elements of good laboratory...

    2018-02-01

    We report the full internal state control of ultracold 23Na87Rb molecules, including vibrational, rotational, and hyperfine degrees of freedom. Starting from a sample of weakly bound Feshbach molecules, we realize the creation of molecules in single hyperfine levels of both the rovibrational ground and excited states with a high-efficiency and high-resolution stimulated Raman adiabatic passage. This capability brings broad possibilities for investigating ultracold polar molecules with different chemical reactivities and interactions with a single molecular species. Moreover, starting from the rovibrational and hyperfine ground state, we achieve rotational and hyperfine control with one- and two-photon microwave spectroscopy to reach levels not accessible by the stimulated Raman transfer. The combination of these two techniques results in complete control over the internal state of ultracold polar molecules, which paves the way to study state-dependent molecular collisions and state-controlled chemical reactions.

    Inadequate regulation of food intake plays an important role in the development of overweight and obesity, and is under the influence of both the internal appetite control system and external environmental cues. Especially in environments where food is overly available, external cues seem to override and/or undermine internal signals, which put severe challenges on the accurate regulation of food intake. By structuring these external cues around five different phases in the food consumption process this paper aims to provide an overview of the wide range of external cues that potentially facilitate or hamper internal signals and with that influence food intake. For each of the five phases of the food consumption process, meal initiation, meal planning, consumption phase, end of eating episode and time till next meal, the most relevant internal signals are discussed and it is explained how specific external cues exert their influence.

    The paper deals with an adaptive control system design problem for a four rotor helicopter or quadrotor. A simple adaptive control design scheme with a parallel feedforward compensator (PFC) in the internal loop of the considered quadrotor will be proposed based on the backstepping strategy. As is well known, the backstepping control strategy is one of the advanced control strategy for nonlinear systems. However, the control algorithm will become complex if the system has higher order relative degrees. We will show that one can skip some design steps of the backstepping method by introducing a PFC in the inner loop of the considered quadrotor, so that the structure of the obtained controller will be simplified and a high gain based adaptive feedback control system will be designed. The effectiveness of the proposed method will be confirmed through numerical simulations.

  7. Intrinsic Sensing and Evolving Internal Model Control of Compact Elastic Module for a Lower Extremity Exoskeleton

    Directory of Open Access Journals (Sweden)

    Likun Wang

    2018-03-01

    Full Text Available To achieve strength augmentation, endurance enhancement, and human assistance in a functional autonomous exoskeleton, control precision, back drivability, low output impedance, and mechanical compactness are desired. In our previous work, two elastic modules were designed for human–robot interaction sensing and compliant control, respectively. According to the intrinsic sensing properties of the elastic module, in this paper, only one compact elastic module is applied to realize both purposes. Thus, the corresponding control strategy is required and evolving internal model control is proposed to address this issue. Moreover, the input signal to the controller is derived from the deflection of the compact elastic module. The human–robot interaction is considered as the disturbance which is approximated by the output error between the exoskeleton control plant and evolving forward learning model. Finally, to verify our proposed control scheme, several experiments are conducted with our robotic exoskeleton system. The experiment shows a satisfying result and promising application feasibility.

    We evaluated the effect of cognitive training among 1,534 participants in the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) randomized controlled trial (RCT) on 5-year improvements in 3 cognitive-specific measures of locus of control-internal, chance, and powerful others. ACTIVE was a multisite RCT (age > or = 65), with 4 groups (memory, reasoning, speed of processing, and no-contact control). Complete 5-year follow-up data were available for 1,534 (55%) of the 2,802 participants. A propensity score model was used to adjust for potential attrition bias. Clinically important improvements (and decrements) in the cognitive-specific locus of control scale scores were defined as greater than or equal to 0.5 SD (medium) and greater than or equal to 1.0 SD (large). Multinomial logistic regression was used to simultaneously contrast those who improved and those who declined with those whose locus of control scale score was unchanged. Statistically significant effects reflecting medium-sized (> or = 0.5 SD) improvements in internal locus of control between baseline and the 5-year follow-up were found for the reasoning and speed of processing intervention groups who were 76% (p control group. No improvement effects were found on the chance or powerful others locus of control measures or for the memory intervention group. Cognitive training that targets reasoning and speed of processing can improve the cognitive-specific sense of personal control over one's life in older adults.

    Full Text Available The purpose of internal control procedure of material and information flows is expression of independent opinion about accounting of material and information flows of the organization, development of recommendations about elimination of detected violations and preparing data to implement automated management accounting system, based on integrated system. Internal control procedure of material and information flows in the enterprise can solve complex of problems about identifying deficiencies in accounting, searching for reserves using information resources, identifying opportunities for implementation of automated management accounting system at the enterprise. Internal control was planned and conducted thus to argue that management statements are free of misstatement, and information flows provide required operability of the entire system. Internal control was carried out on a sample basis and included examining, on a test basis evidence supporting the amounts and disclosures in management reports. The disclosure of information about innovative activities, assessment of compliance with the principles and rules of accounting used in the preparation of management reporting, the review of key performance indicators, as well as evaluating the presentation of management reports are presented.

    To provide evidence for resource allocation and cooperation between domestic and international HIV/AIDS programs in China by analyzing the needs and current levels of resource input in provinces. National and provincial international cooperation program investment and allocation data from 2000 to 2006 were collected. Several factors in each province were analyzed through multiple regression analysis in order to determine whether they had a statistical correlation to the distribution of international HIV/AIDS program resources in China, including: the Gross Domestic Product (GDP), the number of accumulated people living with HIV/AIDS, and the number of accumulated people living with AIDS. Then the Z values were calculated at each provincial level and compared with related international investment. The resource allocation in different program areas were compared with the level of resource input by international and central government HIV/AIDS prevention and control programs through Chi-square test. The international cooperation program investment at local level from 2000 to 2006 were 4893, 24 669, 50 567, 52 950, 112 143, 363 396 and 247 045 thousand RMB respectively, and at national level were 3007, 19 726, 29 035, 37 530, 77 500, 105 786 and 77 035 thousand RMB respectively. There was a statistical correlation between international HIV/AIDS program resource input and the accumulated number of people living with AIDS (R is 0.56 and 0.69 accordingly, and P international resource input and the GDP of each province. International HIV/AIDS cooperation programs did not invest in each province according to its practical needs (R = 0.066, P = 0.725). The international cooperation program investments and needs in different province could not meet completely. The ranks of Z value in Guangdong, Shandong and Jiangsu were 3, 5 and 6, but the ranks of international cooperation program in those provinces were 18, 13 and 28 respectively.

    1993-01-01

    An attitude control strategy for maneuvers of an interconnection of planar bodies in space is developed. It is assumed that there are no exogeneous torques and that torques generated by joint motors are used as means of control so that the total angular momentum of the multibody system is a constant, assumed to be zero. The control strategy utilizes the nonintegrability of the expression for the angular momentum. Large angle maneuvers can be designed to achieve an arbitrary reorientation of the multibody system with respect to an inertial frame. The theoretical background for carrying out the required maneuvers is summarized.

    2017-12-01

    Internal hydraulic control, which occurs when stratified water masses are forced through an abrupt constriction, plays an enormous role in nature on both large and regional scales with respect to dynamics, circulation, and water mass formation. Despite a growing literature on this subject surprisingly few direct observations have been made that conclusively show the existence of and the circumstances related to internal hydraulic control in nature. In this study we present observations from the Little Belt, Denmark, one of three narrow straits connecting the Baltic Sea and the North Sea. The observations (comprised primarily of along-strait, detailed transects of salinity and temperature; continuous observations of flow velocity, salinity, and temperature at a permanent station; and numerous vertical profiles of salinity, temperature, fluorescence, and flow velocity in various locations) show that internal hydraulic control is a frequently occurring phenomenon in the Little Belt. The observations, which are limited to south-going flows of approximately two-layered water masses, show that internal hydraulic control may take either of two configurations, i.e. the lower or the upper layer being the active, accelerating one. This is connected to the depth of the pycnocline on the upstream side and the topography, which is both deepening and contracting toward the narrow part of the Little Belt. The existence of two possible flow configurations is known from theoretical and laboratory studies, but we believe that this has never been observed in nature and reported before. The water masses formed by the intense mixing, which is tightly connected with the presence of control, may be found far downstream of the point of control. The observations show that these particular water masses are associated with chlorophyll concentrations that are considerably higher than in adjacent water masses, showing that control has a considerable influence on the primary production and

    Given rising technology use across all demographic groups, digital interventions offer a potential strategy for increasing access to health information and care. Research is lacking on identifying individual differences that impact willingness to use digital interventions, which may affect patient engagement. Health locus of control, the amount of control an individual believes they have over their own health, may predict willingness to use mobile health (mHealth) applications ('apps') and online trackers. A cross-sectional study (n = 276) was conducted to assess college students' health locus of control beliefs and willingness to use health apps and online trackers. Internal and powerful other health locus of control beliefs predicted willingness to use health apps and online trackers while chance health locus of control beliefs did not. Individuals with internal and powerful other health locus of control beliefs are more willing than those with chance health locus of control beliefs to utilize a form of technology to monitor or change health behaviors. Health locus of control is an easy-to-assess patient characteristic providers can measure to identify which patients are more likely to utilize mHealth apps and online trackers.

    Full Text Available This paper analyzes the general properties of IMP-based controller and presents an internal-model-principle-based (IMP-based specific harmonics repetitive control (SHRC scheme. The proposed SHRC is effective for specific nk±m order harmonics, with n>m≥0 and k=0,1,2,…. Using the properties of exponential function, SHRC can also be rewritten into the format of multiple resonant controllers in parallel, where the control gain of SHRC is n/2 multiple of that of conventional RC (CRC. Therefore, including SHRC in a stable closed-loop feedback control system, asymptotic disturbance eliminating, or reference tracking for any periodic signal only including these specific harmonic components at n/2 times faster error convergence rate compared with CRC can be achieved. Application examples of SHRC controlled three-phase/single-phase grid-connected PWM inverters demonstrate the effectiveness and advantages of the proposed SHRC scheme.

    This study investigated the relationship between locus of control and chosen field of music specialization. The Nowicki-Strickland Locus of Control Scale was designed to assess the construct of locus of control and reinforcement, which is defined as the perception of a connection between one's action and its consequences; the version of the scale used in this study was specifically developed and validated for use with college-aged students by Nowicki (2000). This scale was administered to four separate college-aged groups: music therapy majors, music education majors, applied music majors, and nonmusic majors who also had previous music background and were currently enrolled in a formal college music performance organization. Results indicated that there were indeed, differences among these populations with music therapy majors evidencing a significantly lower internal locus of control. Music education majors and nonmajors evidenced a greater internal level and were not significantly different from each other, yet both were significantly different from the music therapy majors. Music performance majors were also significantly lower in internal control compared to the music education and nonmusic majors, but they were not significantly different from the music therapy majors. This entire line of research has a long history and seems advisable to continue with all music populations, especially potential music therapists in order to investigate those aspects of self-perception that may help or hinder therapeutic effectiveness.

    The internal audit program of the Nuclear Material Control and Accountability (NMCandA) Department at the Oak Ridge Y-12 Plant, through inventory-verification audits, inventory-observation audits, procedures audits, and records audits, evaluates the adequacy of material accounting and control systems and procedures throughout the Plant; appraises and verifies the accuracy and reliability of accountability records and reports; assures the consistent application of generally accepted accounting principles in accounting for nuclear materials; and assures compliance with the Department of Energy (DOE) and NMCandA procedures and requirements. The internal audit program has significantly strengthened the control and accountability of nuclear materials through improving the system of internal control over nuclear materials, increasing the awareness of materials control and accountability concerns within the Plant's material balance areas (MBAs), strengthening the existence of audit trails within the overall accounting system for nuclear materials, improving the accuracy and timeliness of data submitted to the nuclear materials accountability system, auditing the NMCandA accounting system to ensure its accuracy and reliability, and ensuring that all components of that system (general ledgers, subsidiary ledgers, inventory listings, etc.) are in agreement among themselves

    2014-02-01

    To investigate associations between economic stress in childhood and adulthood, and lack of internal health locus of control (HLC), testing the accumulation and critical period life course hypotheses. A cross-sectional public health (postal) survey was conducted in Skåne in 2008, based on a random sample with 28,198 participants in the age interval 18-80 years, with 55% participation. Logistic regressions analyzed associations between childhood and current economic stress, and lack of internal HLC. A 33.7% prevalence of men and 31.8% of women lack internal HLC, which was significantly associated with the covariates included. The accumulation hypothesis was partly supported because combined childhood and adulthood economic stress exposures were significantly associated with lack of internal HLC in a graded manner. The critical period hypothesis was not supported since the association between economic stress in childhood and lack of internal HLC was partly significant in the final model, and the association with adult (current) economic stress was also significant. The accumulation hypothesis was partly supported. The critical period hypothesis was not supported since both childhood and current economic stress experience were significantly associated with lack of internal HLC. Economic conditions in childhood as well as adulthood are plausibly of relevance for HLC.

    2003-12-01

    Full Text Available Abstract Background Controlled clinical trials of health care interventions are either explanatory or pragmatic. Explanatory trials test whether an intervention is efficacious; that is, whether it can have a beneficial effect in an ideal situation. Pragmatic trials measure effectiveness; they measure the degree of beneficial effect in real clinical practice. In pragmatic trials, a balance between external validity (generalizability of the results and internal validity (reliability or accuracy of the results needs to be achieved. The explanatory trial seeks to maximize the internal validity by assuring rigorous control of all variables other than the intervention. The pragmatic trial seeks to maximize external validity to ensure that the results can be generalized. However the danger of pragmatic trials is that internal validity may be overly compromised in the effort to ensure generalizability. We are conducting two pragmatic randomized controlled trials on interventions in the management of hypertension in primary care. We describe the design of the trials and the steps taken to deal with the competing demands of external and internal validity. Discussion External validity is maximized by having few exclusion criteria and by allowing flexibility in the interpretation of the intervention and in management decisions. Internal validity is maximized by decreasing contamination bias through cluster randomization, and decreasing observer and assessment bias, in these non-blinded trials, through baseline data collection prior to randomization, automating the outcomes assessment with 24 hour ambulatory blood pressure monitors, and blinding the data analysis. Summary Clinical trials conducted in community practices present investigators with difficult methodological choices related to maintaining a balance between internal validity (reliability of the results and external validity (generalizability. The attempt to achieve methodological purity can

    2017-10-19

    Using the results of dozens of interviews with key actors involved in tobacco control policymaking, we examine these actors' perceptions of threats to tobacco control policy efforts from international economic policies on trade and investment. We also evaluate, from a legal perspective, the genuine threats that exist or potential challenges that economic policies may pose to the Brazilian government's public health efforts. We find that most actors did not perceive these economic policies as a major threat to tobacco control. Objectively, we found that some threats do exist. For example, Brazil's attempt to ban most tobacco additives and flavorings continues to met resistance at the World Trade Organization.

  4. Rethinking 'flexibilities' in the international drug control system-Potential, precedents and models for reforms.

    Science.gov (United States)

    Collins, John

    2017-01-24

    Much international drug policy debate centres on, what policies are permissible under the international drug treaties, whether member states are openly 'breaching' these treaties by changing national regulatory frameworks and shifting priorities away from a 'war on drugs' approach, and what 'flexibility' exists for policy reform and experimentation at national and local levels. Orthodox interpretations hold that the current system is a US-led 'prohibition regime' that was constructed in an extremely repressive and restrictive manner with almost no flexibility for significant national deviations. This paper challenges these orthodox interpretive frameworks and suggests no absolute and clear dichotomy between strict adherence and 'breaches' of the international treaties. This paper uses historical analysis to highlight the flaws in orthodox policy analyses, which assume a uniform interpretation, implementation and set of policy trajectories towards a 'prohibition regime' in the 20th century. It challenges some existing legal interpretations of the treaties through recourse to historical precedents of flexible interpretation and policy prioritisation. It then examines the legal justifications currently being formulated by member states to explain a shift towards policies which, until recently, have been viewed as outside the permissible scope of the conventions. It then examines a functionalist framework for understanding the likely contours of drug diplomacy in the post-UN General Assembly Special Session (UNGASS) 2016 era. The paper highlights that, contrary to current policy discourses, the international control system has always been implemented in a 'flexible' manner. It demonstrates that drug control goals were repeatedly subsumed to security, development, political stability and population welfare imperatives, or what we might now refer to under the umbrella of 'development issues.' The paper further demonstrates that policy prioritisation, inherent treaty

  6. Implementation of internal model based control and individual pitch control to reduce fatigue loads and tower vibrations in wind turbines

    2018-05-01

    Vibration control and fatigue loads reduction are important issues in large-scale wind turbines. Identifying the vibration frequencies and tuning dampers and controllers at these frequencies are major concerns in many control methods. In this paper, an internal model control (IMC) method with an adaptive algorithm is implemented to first identify the vibration frequency of the wind turbine tower and then to cancel the vibration signal. Standard individual pitch control (IPC) is also implemented to compare the performance of the controllers in term of fatigue loads reduction. Finally, the performance of the system when both controllers are implemented together is evaluated. Simulation results demonstrate that using only IMC or IPC alone has advantages and can reduce fatigue loads on specific components. IMC can identify and suppress tower vibrations in both fore-aft and side-to-side directions, whereas, IPC can reduce fatigue loads on blades, shaft and yaw bearings. When both IMC and IPC are implemented together, the advantages of both controllers can be used. The aforementioned analysis and comparisons were not studied in literature and this study fills this gap. FAST, AreoDyn and Simulink are used to simulate the mechanical, aerodynamic and electrical aspects of wind turbine.

    Full Text Available Global derivatives activity continues to expand although they have provided some of the most devastating financial disasters. The debate on their regulation has always been present and is still unresolved. However, without undervaluing the importance of regulation and the usefulness of an adequate external control, a sound internal control system is essential to prevent new financial scandals. First of all, this paper, through the review of existing recommendations, rules, regulation and academic literature, studies and analyses the need and importance of internal control in derivative usage for risk management. And secondly, through a questionnaire about established policies, procedures and internal controls, it provides evidence related to its usage and control by Spanish savings banks.El uso de los derivados sigue en expansión a pesar de haber ocasionado alguno de los mayoresescándalos financieros.El debate sobre su regulación, todavía sin resolver, ha estado siempre presente.

    2007-05-01

    Full Text Available Abstract For more than two decades, the International Narcotic Control Board (INCB has tried to stop harm reduction and its HIV prevention programs. This posture is based on a fundamental misunderstanding of their responsibilities and of drug addiction itself – i.e. as a public health and clinical care matter made criminal by decree. A recent focal point for the Board's action has been rejecting the use of supervised injection facilities to reduce morbidity and mortality of drug injectors. They single out individual countries and attempt to bully them into rejecting such programs under the banner of the United Nations (falsely and in the name of international treaties. Their unrelenting and unjustified badgering of signatories to the international treaties that established the INCB is not only unjustified; it is an affront to one of the core purposes of the Board itself: to ensure adequate medical supplies and safe use of controlled substances. The INCB's ill-conceived obsession with intravenousaddiction as a crime flies in the face of the medical view and policies of the World Health Organization and the universally endorsed principles of the General Assembly of the United Nations. The latest target of the INCB is North America's only supervised injection facility, Insite, located in the inner city of Vancouver, Canada. Using the power of their office to meddle in matters of public health for individual nations is without medical, scientific or legal justification. But, most importantly, it is a matter of lifeand death for these most marginalized of citizens. The empirical evidence remains that a significant portion of the continued growth of the AIDS pandemic is due to injecting drug use, and the INCB's intrusion will inevitably result in additional deaths due to preventable HIV infections and drug overdoses. So we are very pleased to call to our readers' attention to a recent report produced by the Canadian HIV/AIDS Legal Network and the

    Full Text Available In order to control the management of activities for achieve the objectives, the managers at all levels of the hierarchy must have relevant information on the organization's events and activities, in an appropriate form and detail. Thus, they can assume their responsibilities. In this context, we considered that important of organizing and implementing in the public entities of the system of internal managerial control. This system provides reasonable assurance that the organization's objectives will be achieved in terms of efficiency, efficacy, economically. For this purpose, we have carried out a documentary research of both specialized papers and the applicable regulations in force in Romania in the field of managerial internal control within the public entities, as well as empirical research. Thus, in a conjunct survey, we conducted a survey on the implementation of the managerial internal control system in different public institutions in Romania with the central objective to highlight the perception of the staff involved in this tool at the disposal of the management.

    Operating the International Space Station (ISS) involves an indefinite, continuous series of long-duration international missions, and this requires an unprecedented degree of cooperation across multiple sites, organizations, and nations. Both junior and senior mission control personnel have had to find ways to address the cultural challenges inherent in such work, but neither have had systematic training in how to do so. The goals of this study were to identify and evaluate the major cultural challenges faced by ISS mission control personnel and to highlight the approaches that they have found most effective to surmount these challenges. We pay particular attention to the approaches successfully employed by the senior personnel and the training needs identified by the junior personnel. We also evaluate the extent to which the identified approaches and needs are consistent across the two samples. METHODS: Participants included a sample of 14 senior ISS flight controllers and a contrasting sample of 12 more junior controllers. All participants were mission operations specialists chosen on the basis of having worked extensively with international partners. Data were collected using a semi-structured qualitative interview and content analyzed using an iterative process with multiple coders and consensus meetings to resolve discrepancies. RESULTS: The senior respondents had substantial consensus on several cultural challenges and on key strategies for dealing with them, and they offered a wide range of specific tactics for implementing these strategies. Data from the junior respondents will be presented for the first time at the meeting. DISCUSSION: Although specific to American ISS personnel, our results are consistent with recent management, cultural, and aerospace research on other populations. We aim to use our results to improve training for current and future mission control personnel working in international or multicultural mission operations teams.

    According to the results of the large trials on carotid endarterectomy (CEA), this type of surgery is only warranted if perioperative mortality and morbidity are kept considerably low. Less attention has been paid to methods of cerebral protection during CEA, although intraoperative transcranial Doppler (TCD) can visualise intracerebral microemboli (MES) during routine carotid dissection, although MES occur throughout the CEA, only those during dissection are related to neurological outcome. Prevention of MES by means of early control of the distal internal carotid artery dislodging from the carotid artery plaque during dissection is very likely the mechanism behind an eventual benefit from this approach. Hence, the amount of MES might serve as a surrogate parameter for the risk of periprocedural neurological events. So, the aim of the present study was to evaluate whether early control of the distal carotid artery during CEA is capable of reducing the number of MES by means of a prospective randomised trial. Twenty-eight patients (29 procedures) could be prospectively included in our study. Before surgery we randomly assigned the patients to two groups: group A (N.=12): CEA by means of early control of the distal internal carotid artery; group B (N.=17): CEA with dissection of the total carotid bifurcation before clamping the arteries. Periprocedurally, we continuously monitored the cerebral blood flow in the ipsilateral middle cerebral artery by means of TCD. Pre- and postoperative morbidity were independently verified by a neurologist control of the distal internal carotid artery did not reduce the occurrence of MES during dissection of the carotid bifurcation. Also, the total number of MES throughout the procedure and postoperatively was comparable between both groups. The procedure related times as well as the clinical outcome did not differ significantly. Thus, early control of the distal internal carotid artery has got no advantage but also no disadvantage

  13. Potential International Approaches to Ownership/Control of Human Genetic Resources.

    Rhodes, Catherine

    2016-09-01

    In its governance activities for genetic resources, the international community has adopted various approaches to their ownership, including: free access; common heritage of mankind; intellectual property rights; and state sovereign rights. They have also created systems which combine elements of these approaches. While governance of plant and animal genetic resources is well-established internationally, there has not yet been a clear approach selected for human genetic resources. Based on assessment of the goals which international governance of human genetic resources ought to serve, and the implications for how they will be accessed and utilised, it is argued that common heritage of mankind will be the most appropriate approach to adopt to their ownership/control. It does this with the aim of stimulating discussion in this area and providing a starting point for deeper consideration of how a common heritage of mankind, or similar, regime for human genetic resources would function and be implemented.

  14. Simulation and Development of Internal Model Control Applications in the Bayer Process

    Science.gov (United States)

    Colombé, Ph.; Dablainville, R.; Vacarisas, J.

    Traditional PID feedback control system is limited in its use in the Bayer cycle due to the important and omnipresent time delays which can lead to stability problems and sluggish response. Advanced modern control techniques are available, but suffer in an industrial environment from a lack of simplicity and robustness. In this respect the Internal Model Control (IMC) method may be considered as an exception. After a brief review of the basic theoretical principles behind IMC, an IMC scheme is developed to work with single-input, single-output, discrete-time, nonlinear systems. Two applications of IMC in the Bayer process, both in simulations and on industrial plants, are then described: control of the caustic soda concentration of the aluminate liquor and control of the A12O3/Na20 caust. ratio of the digested slurry, Finally, the results obtained make this technique quite attractive for the alumina industry.

    2015-01-01

    Full Text Available Internal model control (IMC design method based on quasi-LPV (Linear Parameter Varying system is proposed. In this method, the nonlinear model is firstly transformed to the linear model based on quasi-LPV method; then, the quadrotor nonlinear motion function is transformed to transfer function matrix based on the transformation model from the state space to the transfer function; further, IMC is designed to control the controlled object represented by transfer function matrix and realize quadrotor trajectory tracking. The performance of the controller proposed in this paper is tested by tracking for three reference trajectories with drastic changes. The simulation results indicate that the control method proposed in this paper has stronger robustness to parameters uncertainty and disturbance rejection performance.

    Huning, Therese; Barshi, Immanuel; Schmidt, Lacey

    2009-01-01

    The Mission Operations Directorate (MOD) of the Johnson Space Center is responsible for providing continuous operations support for the International Space Station (ISS). Operations support requires flight controllers who are skilled in team performance as well as the technical operations of the ISS. Space Flight Resource Management (SFRM), a NASA adapted variant of Crew Resource Management (CRM), is the competency model used in the MOD. ISS flight controller certification has evolved to include a balanced focus on development of SFRM and technical expertise. The latest challenge the MOD faces is how to certify an ISS flight controller (Operator) to a basic level of effectiveness in 1 year. SFRM training uses a twopronged approach to expediting operator certification: 1) imbed SFRM skills training into all Operator technical training and 2) use senior flight controllers as mentors. This paper focuses on how the MOD uses senior flight controllers as mentors to train SFRM skills.

    High performance vibration isolators are required for ground based gravitational wave detectors. To attain very high performance at low frequencies we have developed multistage isolators for the proposed Australian International Gravitational Observatory detector in Australia. New concepts in vibration isolation including self-damping, Euler springs, LaCoste springs, Roberts linkages, and double preisolation require novel sensors and actuators. Double preisolation enables internal feedback to be used to suppress low frequency seismic noise. Multidegree of freedom control systems are required to attain high performance. Here we describe the control components and control systems used to control all degrees of freedom. Feedback forces are injected at the preisolation stages and at the penultimate suspension stage. There is no direct actuation on test masses. A digital local control system hosted on a digital signal processor maintains alignment and position, corrects drifts, and damps the low frequency linear and torsional modes without exciting the very high Q-factor test mass suspension. The control system maintains an optical cavity locked to a laser with a high duty cycle even in the absence of an autoalignment system. An accompanying paper presents the mechanics of the system, and the optical cavity used to determine isolation performance. A feedback method is presented, which is expected to improve the residual motion at 1 Hz by more than one order of magnitude.

    A series of seismic reliability proving tests of nuclear power plant facilities has been carried out by the Nuclear Power Engineering Test Center (NUPEC), using a large-scale, high-performance vibration table at Todatsu Engineering Laboratory, sponsored by the Ministry of International Trade and Industry (MITI). In 1985, a seismic proving test of PWR reactor core internals was conducted on a full scale test model. The results showed that the test components proved to have the safe and reliable function of control rod cluster insertion during the seismic proving test and to have the structural soundness against earthquake. Subsequently, detailed analyses and evaluation of these test results were performed, and analysis methods for evaluating the strength to withstand earthquakes were established. After that, seismic analyses and evaluations of actual reactor core internals were performed by these analysis methods, and the safety and reliability of PWR reactor core internals were confirmed. This paper mainly focuses on the function of control rod cluster insertion during an earthquake

    The influences of feedback control and internal heat source on the onset of Rayleigh-Bénard convection in a horizontal nanofluid layer is studied analytically due to Soret and Dufour parameters. The confining boundaries of the nanofluid layer (bottom boundary-top boundary) are assumed to be free-free, rigid-free, and rigid-rigid, with a source of heat from below. Linear stability theory is applied, and the eigenvalue solution is obtained numerically using the Galerkin technique. Focusing on the stationary convection, it is shown that there is a positive thermal resistance in the presence of feedback control on the onset of double-diffusive convection, while there is a positive thermal efficiency in the existence of internal heat generation. The possibilities of suppress or augment of the Rayleigh-Bénard convection in a nanofluid layer are also discussed in detail.

  2. Aging considerations for PWR [pressurized water reactor] control rod drive mechanisms and reactor internals

    Ware, A.G.

    1988-01-01

    This paper describes age-related degradation mechanisms affecting life extension of pressurized water reactor control rod drive mechanisms and reactor internals. The major sources of age-related degradation for control rod drive mechanisms are thermal transients such as plant heatups and cooldowns, latchings and unlatchings, long-term aging effects on electrical insulation, and the high temperature corrosive environment. Flow induced loads, the high-temperature corrosive environment, radiation exposure, and high tensile stresses in bolts all contribute to aging related degradation of reactor internals. Another problem has been wear and fretting of instrument guide tubes. The paper also discusses age-related failures that have occurred to date in pressurized water reactors

    Discussions about racial and ethnic differences may allow international, transracial adoptive families to construct multiracial and/or multiethnic family identities. However, little is known about the ways family communication influences how discussions about racial and ethnic differences occur. This study examined associations between observed family communication constructs, including engagement, warmth, and control, and how adoptive families discuss racial and ethnic differences using a sample of families with adolescent-aged children adopted internationally from South Korea ( N = 111 families, 222 adolescents). Using data collected during mid-adolescence and again during late adolescence, higher levels of maternal control and positive adolescent engagement were independently associated with a greater likelihood that family members acknowledged the importance of racial and ethnic differences and constructed a multiracial and/or multiethnic family identity. Adolescent engagement was also related to a greater likelihood that family members disagreed about the importance of racial and ethnic differences, and did not build a cohesive identity about differences.

    The U.S. Government has regulations in place to control the international traffic in arms. The growth of science and engineering since the inception of this governmental effort has produced many remarkable military-related systems, some existing purely for information gathering and defensive purposes. Defense trade is now a multi-billion dollar multi-national industry. U.S. defense trade in particular is strongly influenced by national security and foreign policy rather than economic impact, unlike many of its competitors. A brief history of the International Traffic in Arms Regulations will be presented, followed by an overview of some of the categories on the United States Munitions List and the Missile Technology Control Regime Annex which have strong connections to physics in terms of theory, concepts, and measurement. Following this category overview, particular emphasis will be given to the existing radiation hardening standards for semiconductors, and the basic structure of night vision devices.

    A two-stage, thermally coupled fluidized-bed reactor system has been developed for energy-efficient conversion of tar-sand bitumen to synthetic crude oil. Modeling and temperature control of a system are addressed in this study. A process model and transfer function are determined by a transient response technique and the reactor temperature are controlled by PI controllers with tuning settings determined by an internal model control (IMC) strategy. Using the IMC tuning method, sufficiently good control performance was experimentally observed without lengthy on-line tuning. It is shown that IMC strategy provides a means to directly use process knowledge to make a control decision. Although this control method allows for fine tuning by adjusting a single tuning parameter, it is not easy to determine the optimal value of this tuning parameter, which must be specified by the user. A novel method is presented to evaluate that parameter, which must be specified by the user. A novel method is presented to evaluate that parameter in this study. It was selected based on the magnitude of elements on the off-diagonal of the relative gain array to account for the effect of thermal coupling on control performance. It is shown that this method provides stable and fast control of reactor temperatures. By successfully decoupling the system, a simple method of extending the IMC tuning technique to multiinput/multioutput systems is obtained.

    Full Text Available Abstract To date, the reliability of induction of a depressive-like state using chronic stress models is confronted by many methodological limitations. We believe that the modifications to the stress paradigm in mice proposed herein allow some of these limitations to be overcome. Here, we discuss a variant of the standard stress paradigm, which results in anhedonia. This anhedonic state was defined by a decrease in sucrose preference that was not exhibited by all animals. As such, we propose the use of non-anhedonic, stressed mice as an internal control in experimental mouse models of depression. The application of an internal control for the effects of stress, along with optimized behavioural testing, can enable the analysis of biological correlates of stress-induced anhedonia versus the consequences of stress alone in a chronic-stress depression model. This is illustrated, for instance, by distinct physiological and molecular profiles in anhedonic and non-anhedonic groups subjected to stress. These results argue for the use of a subgroup of individuals who are negative for the induction of a depressive phenotype during experimental paradigms of depression as an internal control, for more refined modeling of this disorder in animals.

    An experimental study was conducted to assess the feasibility of internal voltage regulation of fuel cell systems. Two methods were tested. In one, reactant partial pressure was used as the voltage control parameter and in the other reactant total pressure was used for control. Both techniques were breadboarded and tested on a single alkaline-electrolyte fuel cell. Both methods were found to be possible forms of regulation, however, of the two the total pressure technique would be more efficient, simpler to apply and would provide better transient characteristics.

    A field programmable gate array-based digital low level rf (LLRF) control system will be used in the International Linear Collider (ILC) in order to satisfy the rf stability requirements. The digital LLRF control system with four different intermediate frequencies has been developed to decrease the required number of analog-to-digital converters in this system. The proof of concept of this technique was demonstrated at the Superconducting RF Test Facility in the High Energy Accelerator Research Organization, Japan. The amplitude and phase stability has fulfilled the ILC requirements.

  20. Stair Climbing Control for 4-DOF Tracked Vehicle Based on Internal Sensors

    Full Text Available In search-and-rescue missions, multi-degrees-of-freedom (DOF tracked robots that are equipped with subtracks are commonly used. These types of robots have superior locomotion performance on rough terrain. However, in teleoperated missions, the performance of tracked robots depends largely on the operators’ ability to control every subtrack appropriately. Therefore, an autonomous traversal function can significantly help in the teleoperation of such robots. In this paper, we propose a planning and control method for 4-DOF tracked robots climbing up/down known stairs automatically based on internal sensors. Experimental results obtained using mockup stairs verify the effectiveness of the proposed method.

    Contemporary space engineering advanced new problem before theoretical mechanics and motion control theory: a spacecraft directed respinup by the weak restricted control internal forces. The paper presents some results on this problem, which is very actual for energy supply of information mini-satellites (for communication, geodesy, radio- and opto-electronic observation of the Earth et al.) with electro-reaction plasma thrusters and gyro moment cluster based on the reaction wheels or the control moment gyros. The solution achieved is based on the methods for synthesis of nonlinear robust control and on rigorous analytical proof for the required spacecraft rotation stability by Lyapunov function method. These results were verified by a computer simulation of strongly nonlinear oscillatory processes at respinuping of a flexible spacecraft.

    We tested perceived head-on-feet orientation and the direction of vestibular-evoked balance responses in passively and actively held head-turned postures. The direction of vestibular-evoked balance responses was not aligned with perceived head-on-feet orientation while maintaining prolonged passively held head-turned postures. Furthermore, static visual cues of head-on-feet orientation did not update the estimate of head posture for the balance controller. A prolonged actively held head-turned posture did not elicit a rotation in the direction of the vestibular-evoked balance response despite a significant rotation in perceived angular head posture. It is proposed that conscious perception of head posture and the transformation of vestibular signals for standing balance relying on this head posture are not dependent on the same internal representation. Rather, the balance system may operate under its own sensorimotor principles, which are partly independent from perception. Vestibular signals used for balance control must be integrated with other sensorimotor cues to allow transformation of descending signals according to an internal representation of body configuration. We explored two alternative models of sensorimotor integration that propose (1) a single internal representation of head-on-feet orientation is responsible for perceived postural orientation and standing balance or (2) conscious perception and balance control are driven by separate internal representations. During three experiments, participants stood quietly while passively or actively maintaining a prolonged head-turned posture (>10 min). Throughout the trials, participants intermittently reported their perceived head angular position, and subsequently electrical vestibular stimuli were delivered to elicit whole-body balance responses. Visual recalibration of head-on-feet posture was used to determine whether static visual cues are used to update the internal representation of body configuration

    The objective of this study is to perform a comparative analysis between the Brazilian legislation and internationals protocols, with respect to the quality control tests for computerized tomography. We used 07 references, published from 1998-2012: the Protocolo Brasileiro - Portaria 453/98 SVS/MS and the Guia de Radiodiagnostico Medico da ANVISA; Quality Assurance Programme for Computed Tomography: Diagnostic and Therapy Applications of the IAEA; European Protocol - European Guidelines on Quality Criteria for Computed Tomography of the EUR No. 16262 EN; Radiation Protection No. 162 - Criteria for Acceptability of Medical Radiology, Nuclear Medicine and Radiotherapy of the European Commission; the Protocols of Control de Calidad en Radiodiagnostico IAEA / ARCAL XLIX; and the Protocolo Espanol de Control de Calidad en Radiodignostico. The comparative analysis of these legislations was based on aspects of tolerance / limit, frequency and objectives of the recommended tests. Were found 18 tests in the Brazilian legislation. The tests were grouped according to their nature (dosimetric tests / exposure and geometric tests and image quality tests). Among the evaluated protocols was identified divergence between tests contained in the documents and the criteria of assessment set out in this work. It is clear, moreover, that for certain documents are not observed tolerances, well-defined methodologies and even frequency of testing. We conclude that the current legislation in Brazil differs in certain respects from international protocols analyzed, although this has a great numbers of quality control tests. However, it is necessary that the Brazilian legislation takes into account technological advances presented to time

    2015-09-01

    Full Text Available This article analyzes what can happen to forced returnees upon arrival in their country of nationality. Subjective configurations of state agents in the Global South have created return risks, which in turn transform subjectivities of post-colonial citizens. The article contributes to this Special Issue by tracing repercussions of the externalization and internalization of border controls. In the case of Cameroon, these connections have resulted in the criminalization of emigration. Aspiring migrants are prosecuted if their departure projects fail to respect the entry requirements of countries in the Global North. The article is based on research conducted in Douala, Cameroon, in the form of discussions with control agents at the international airport, investigations at a prison, a review of related case law, police registers and interviews with Cameroonians returnees (November 2013–January 2014. Border controls and connected anti-fraud programs suppress family-based forms of solidarity and allow only for subjectivities rooted in state-managed forms of national identity. The article illustrates how efforts to combat fraud fuel corruption in returnees’ social networks, whereby, instead of receiving remittances, families in emigration countries have to mobilize financial resources in order to liberate returnees from police stations or prison complexes. Migration related detention of nationals in the Global South highlights the growing significance of exit controls in migration management.

  10. Control Scheme Formulation for the Production of Hydrogen on Demand to Feed an Internal Combustion Engine

    2016-12-01

    Full Text Available In this work, a control strategy is presented to produce hydrogen on demand to feed an internal combustion (IC engine. For this purpose, the modeling of the IC engine fueled by gasoline blended with 10 % v/v of anhydrous ethanol (E10 and hydrogen as an additive is developed. It is considered that the hydrogen gas is produced according to the IC engine demand, and that the hydrogen gas is obtained by an alkaline electrolyzer. The gasoline–ethanol blend added into the combustion chamber is determined according to the stoichiometric ratio and the production of hydrogen gas is regulated by a proportional and integral controller (P.I.. The controller reference is varying according to the mass flow air induced into the cylinder, in order to ensure an adequate production of hydrogen gas for any operating condition of the IC engine. The main contribution of this work is the control scheme developed, through simulation, in order to produce hydrogen on demand for any operating point of an internal combustion engine fueled by an E10 blend. The simulation results showed that the use of hydrogen gas as an additive in an E10 blend decreases the E10 fuel consumption 23 % on average, and the thermal efficiency is increased approximately 2.13 % , without brake power loss in the IC engine.

  11. Design of complex bone internal structure using topology optimization with perimeter control.

    Large facial bone loss usually requires patient-specific bone implants to restore the structural integrity and functionality that also affects the appearance of each patient. Titanium alloys (e.g., Ti-6Al-4V) are typically used in the interfacial porous coatings between the implant and the surrounding bone to promote stability. There exists a property mismatch between the two that in general leads to complications such as stress-shielding. This biomechanical discrepancy is a hurdle in the design of bone replacements. To alleviate the mismatch, the internal structure of the bone replacements should match that of the bone. Topology optimization has proven to be a good technique for designing bone replacements. However, the complex internal structure of the bone is difficult to mimic using conventional topology optimization methods without additional restrictions. In this work, the complex bone internal structure is recovered using a perimeter control based topology optimization approach. By restricting the solution space by means of the perimeter, the intricate design complexity of bones can be achieved. Three different bone regions with well-known physiological loadings are selected to illustrate the method. Additionally, we found that the target perimeter value and the pattern of the initial distribution play a vital role in obtaining the natural curvatures in the bone internal structures as well as avoiding excessive island patterns.

    To prepare the French Accreditation Committee (COFRAC) visit for initial certification of our medical laboratory, our direction evaluated its quality management system (QMS) and all its technical activities. This evaluation was performed owing an internal audit. This audit was outsourced. Auditors had an expertise in audit, a whole knowledge of biological standards and were independent. Several nonconformities were identified at that time, including a lack of control of several steps of the internal audit process. Hence, necessary corrective actions were taken in order to meet the requirements of standards, in particular, the formalization of all stages, from the audit program, to the implementation, review and follow-up of the corrective actions taken, and also the implementation of the resources needed to carry out audits in a pre-established timing. To ensure an optimum control of each step, the main concepts of risk management were applied: process approach, root cause analysis, effects and criticality analysis (FMECA). After a critical analysis of our practices, this methodology allowed us to define our "internal audit" process, then to formalize it and to follow it up, with a whole documentary system.

  15. β-arrestins negatively control human adrenomedullin type 1-receptor internalization.

    Adrenomedullin (AM) is a potent hypotensive peptide that exerts a powerful variety of protective effects against multiorgan damage through the AM type 1 receptor (AM 1 receptor), which consists of the calcitonin receptor-like receptor (CLR) and receptor activity-modifying protein 2 (RAMP2). Two β-arrestin (β-arr) isoforms, β-arr-1 and β-arr-2, play a central role in the agonist-induced internalization of many receptors for receptor resensitization. Notably, β-arr-biased agonists are now being tested in phase II clinical trials, targeting acute pain and acute heart failure. Here, we examined the effects of β-arr-1 and β-arr-2 on human AM 1 receptor internalization. We constructed a V5-tagged chimera in which the cytoplasmic C-terminal tail (C-tail) of CLR was replaced with that of the β 2 -adrenergic receptor (β 2 -AR), and it was transiently transfected into HEK-293 cells that stably expressed RAMP2. The cell-surface expression and internalization of the wild-type or chimeric receptor were quantified by flow cytometric analysis. The [ 125 I]AM binding and the AM-induced cAMP production of these receptors were also determined. Surprisingly, the coexpression of β-arr-1 or -2 resulted in significant decreases in AM 1 receptor internalization without affecting AM binding and signaling prior to receptor internalization. Dominant-negative (DN) β-arr-1 or -2 also significantly decreased AM-induced AM 1 receptor internalization. In contrast, the AM-induced internalization of the chimeric AM 1 receptor was markedly augmented by the cotransfection of β-arr-1 or -2 and significantly reduced by the coexpression of DN-β-arr-1 or -2. These results were consistent with those seen for β 2 -AR. Thus, both β-arrs negatively control AM 1 receptor internalization, which depends on the C-tail of CLR. Copyright © 2017 Elsevier Inc.

    1990-07-01

    It is now universally recognized that arms control treaties should be effectively verified. The most objective, flexible and cost-effective means to verify the majority of multilateral treaties would be through a new agency under the United Nations. As a cooperative international effort to develop both the technology and the political framework for arms control verification, a United Nations verification agency (UNVA) would speed up and help secure the disarmament process by: verifying a number of existing and future treaties; investigating alleged breaches of treaties; and certifying, upon request, that voluntary arms control and confidence-building measures have been carried out. This paper presents the case for such a proposal, outlines a possible institutional configuration, considers the possibilities for growth and discusses the challenges facing the establishment of such an agency.

    This book adds a significant new contribution to the crucial climate change/global warming debate. Incorporating the key political and legal considerations into 'real world' applied economic analysis, the authors provide a unique focus on the wider political economy of the problem. All the key issues of controlling climate change (costs, timing and degree of stabilisation, ecological tax reform, developing countries, and evolution of international agreements), are placed firmly within the current legal and political economy context, with state-of-the art economic techniques introduced to analyse different policy proposals. Covering both the developing and developed world, this book identifies important new policies to foster effective agreements on emissions and prevent global warming - realistic policies, likely to receive support at both international and domestic levels.

    During assembly of the International Space Station, the Internal Thermal Control Systems in adjacent modules are connected by jumper hoses referred to as integrated hose assemblies (IHAs). A test of an IHA has been performed at the Marshall Space Flight Center to determine whether the pressure in an IHA filled with heat transfer fluid would exceed the maximum design pressure when subjected to elevated temperatures (up to 60 C (140 F)) that may be experienced during storage or transportation. The results of the test show that the pressure in the IHA remains below 227 kPa (33 psia) (well below the 689 kPa (100 psia) maximum design pressure) even at a temperature of 71 C (160 F), with no indication of leakage or damage to the hose. Therefore, based on the results of this test, the IHA can safely be filled with coolant prior to launch. The test and results are documented in this Technical Memorandum.

    Full Text Available Background: Lacking of internal control in majority of the PCR realated searchesis one of the most important items yet. Using sensitive and specialized laboratory techniques such as PCR is necessary to cryptococosis diagnosis. Different methods to detect this pathogen exist. Generally, culturing based methods are time consuming and have low sensitivity and need enough experience and equipments to data analyzing. Further painting based methods have no sufficient sensitivity as well. As a result, molecular techniques such as PCR are more appropriate to diagnosis purposes, but different data gathered from non standard tests supposed to be one of the deficiencies of this powerful molecular technique. This aim of this study was to design and produce the plasmid amplification internal control (IAC to identify the restrictors in Cryptococcus neoformans PCR test and its future applications in the routine diagnostic laboratories. Materials and methods: In this study to produce internal control, first the special PCR primers based on Gene target 16SrRNA for optimized molecular detection and then sensitivity and character were identified. Then, the composite primers for IAC C. neoformans was designed, replicated and clonized as well. The replicated IAC C. neoformans was attached to pTZ57R and transformed and colonized in E.coli JM107. The minimum IC number of each PCR reaction was studied using dilution and PCR reaction spectrum with IC. Results: The size of C. neoformans diagnostic product with its special primers was 415 bp and IAC C. neoformans amplicon is 661 bp, which have desired deference in the size (246 bp. The minimum IC number was identified 1000 in each reaction. The min/max sensitivity of PCR test with IC for C. neoformans DNA was identified between 100 particle to 3 million yeasts. There was no unwanted product in the character test with different agents. Conclusion: In spite of high rate and exclusivity of PCR technique, one of the main

    1983-01-01

    Ever increasing demands for nuclear power plant safety and availability imply a need for the introduction of modern measurement and control methods, together with data processing techniques based on the latest advances in electronic components, transducers and computers. Nuclear power plant control and instrumentation is therefore an extremely rapidly developing field. The present symposium, held in Munich, FR Germany, was prepared with the help of the IAEA International Working Group on Nuclear Power Plant Control and Instrumentation and organized in close co-operation with the Gesellschaft fur Reaktorsicherheit, Federal Republic of Germany. A number of developments were highlighted at the Munich symposium: - The increased use of computers can bring clear advantages and this technique is now proven as a tool for supervising and controlling plant operation. Advanced computerized systems for operator support are being developed on a large scale in many countries. The progress in this field is quite obvious, especially in disturbance analysis, safety parameter display, plant operator guidance and plant diagnostics. The new trend of introducing computers and microprocessors in protection systems makes it easy to implement 'defence-in-depth' strategies which give better assurance of correct system responses and also prevent unnecessary reactor trips, thus improving plant availability. The introduction of computerized systems for control of reactor power, reactor water level and reactor pressure as well as for reactor start-up and shut-down could improve the reliability and availability of nuclear power plants. The rapid technical development in the area of control and instrumentation makes it necessary to plan for at least one replacement of obsolete equipment in the course of the 30 years lifetime of a nuclear power plant and retrofitting of currently operating reactors with new control systems. Major design improvements and regulatory requirements also require

    Full Text Available Cancer is a major cause of mortality and morbidity throughout the world, including the countries of North-East and South-East Asia. Assessment of burden through cancer registration, determination of risk and protective factors, early detection and screening, clinical practice, interventions for example in vaccination, tobacco cessation efforts and palliative care all should be included in comprehensive cancer control programs. The degree to which this is possible naturally depends on the resources available at local, national and international levels. The present review concerns elements of cancer control programs established in China, Taiwan, Korea, and Japan in North-East Asia, Viet Nam, Thailand, Malaysia, and Indonesia as representative larger countries of South-East Asia for comparison, using the published literature as a guide. While major advances have been made, there are still areas which need more attention, especially in South-East Asia, and international cooperation is essential if standard guidelines are to be generated to allow effective cancer control efforts throughout the Far East.

    China's exporting behaviour of nuclear items had been disconnected from the international non-proliferation regime such as IAEA safeguards and export control related with peaceful use of nuclear energy since 1970s. Especially, China had been one of principle suppliers of nuclear facility and technologies to Pakistan and Iran which had developed nuclear weapon programs. On the other hand, according to the rapid growth of economic scale after China began to open to the world, an active program for nuclear power plant as an electricity source had established. This means that China have surfaced as a big market to Korean nuclear industries. Regarding this, the paper dealt with the nuclear export control matters, i.e. the history of nuclear export control system and analyzed on background of enforcement of U.S.-China Nuclear Cooperation Agreement that had been apolitical issue between U.S. and China. Prospects toward conforming its nuclear export policies, laws and regulations to international standards also analyzed in results

    The increasing demands on safety, emission and fuel consumption require more accurate control models of micro internal combustion swing engine (MICSE). The objective of this paper is to investigate the constant speed control models of four-stroke MICSE. The operation principle of the four-stroke MICSE is presented based on the description of MICSE prototype. A two-level Petri net based hybrid model is proposed to model the four-stroke MICSE engine cycle. The Petri net subsystem at the upper level controls and synchronizes the four Petri net subsystems at the lower level. The continuous sub-models, including breathing dynamics of intake manifold, thermodynamics of the chamber and dynamics of the torque generation, are investigated and integrated with the discrete model in MATLAB Simulink. Through the comparison of experimental data and simulated DC voltage output, it is demonstrated that the hybrid model is valid for the four-stroke MICSE system. A nonlinear model is obtained from the cycle average data via the regression method, and it is linearized around a given nominal equilibrium point for the controller design. The feedback controller of the spark timing and valve duration timing is designed with a sequential loop closing design approach. The simulation of the sequential loop closure control design applied to the hybrid model is implemented in MATLAB. The simulation results show that the system is able to reach its desired operating point within 0.2 s, and the designed controller shows good MICSE engine performance with a constant speed. This paper presents the constant speed control models of four-stroke MICSE and carries out the simulation tests, the models and the simulation results can be used for further study on the precision control of four-stroke MICSE.

We evaluated the routine inclusion of 52 single-nucleotide polymorphisms (SNPs) as internal reference in our polymerase chain reaction (PCR) settings to obtain a positive internal control for fetal DNA. DNA from 223 plasma samples of pregnant women was screened for RHD Exons 3, 4, 5, and 7 in a multiplex PCR including 52 SNPs divided into four primer pools. Amplicons were analyzed by single-base extension and the GeneScan method in a genetic analyzer. Results of D screening were compared to standard RHD genotyping of amniotic fluid or real-time PCR of fetal DNA from maternal plasma. The vast majority of all samples (97.8%) demonstrated differences in maternal and fetal SNP patterns when tested with four primer pools. These differences were not observed in less than 2.2% of the samples most probably due to an extraction failure for adequate amounts of fetal DNA. Comparison of the fetal genotypes with independent results did not reveal a single false-negative case among samples (n = 42) with positive internal control and negative fetal RHD typing. Coamplification of 52 SNPs with RHD-specific sequences for fetal blood group determination introduces a valid positive control for the amplification of fetal DNA to avoid false-negative results. This new approach does not require a paternal blood sample. It may also be applicable to other assays for fetal genotyping in maternal blood samples. © 2012 American Association of Blood Banks.

    To screen the stable expression genes related to the stress (strong light, dehydration and temperature shock) we applied Absolute real-time PCR technology to determine the transcription numbers of the selected test genes in P orphyra yezoensis, which has been regarded as a potential model species responding the stress conditions in the intertidal. Absolute real-time PCR technology was applied to determine the transcription numbers of the selected test genes in P orphyra yezoensis, which has been regarded as a potential model species in stress responding. According to the results of photosynthesis parameters, we observed that Y(II) and F v/ F m were significantly affected when stress was imposed on the thalli of P orphyra yezoensis, but underwent almost completely recovered under normal conditions, which were collected for the following experiments. Then three samples, which were treated with different grade stresses combined with salinity, irradiation and temperature, were collected. The transcription numbers of seven constitutive expression genes in above samples were determined after RNA extraction and cDNA synthesis. Finally, a general insight into the selection of internal control genes during stress response was obtained. We found that there were no obvious effects in terms of salinity stress (at salinity 90) on transcription of most genes used in the study. The 18S ribosomal RNA gene had the highest expression level, varying remarkably among different tested groups. RPS8 expression showed a high irregular variance between samples. GAPDH presented comparatively stable expression and could thus be selected as the internal control. EF-1α showed stable expression during the series of multiple-stress tests. Our research provided available references for the selection of internal control genes for transcripts determination of P. yezoensis.

    The ISS (International Space Station) ITCS (Internal Thermal Control System) includes two internal coolant loops that utilize an aqueous based coolant for heat transfer. A silver salt biocide had previously been utilized as an additive in the coolant formulation to control the growth and proliferation of microorganisms within the coolant loops. Ground-based and in-flight testing demonstrated that the silver salt was rapidly depleted, and did not act as an effective long-term biocide. Efforts to select an optimal alternate biocide for the ITCS coolant application have been underway and are now in the final stages. An extensive evaluation of biocides was conducted to down-select to several candidates for test trials and was reported on previously. Criteria for that down-select included: the need for safe, non-intrusive implementation and operation in a functioning system; the ability to control existing planktonic and biofilm residing microorganisms; a negligible impact on system-wetted materials of construction; and a negligible reactivity with existing coolant additives. Candidate testing to provide data for the selection of an optimal alternate biocide is now in the final stages. That testing has included rapid biocide effectiveness screening using Biolog MT2 plates to determine minimum inhibitory concentration (amount that will inhibit visible growth of microorganisms), time kill studies to determine the exposure time required to completely eliminate organism growth, materials compatibility exposure evaluations, coolant compatibility studies, and bench-top simulated coolant testing. This paper reports the current status of the effort to select an alternate biocide for the ISS ITCS coolant. The results of various test results to select the optimal candidate are presented.

    2016-06-01

    Full Text Available The modern grid rules forces DFIG to withstand and operate during single as well as multiple low voltage grid faults. The system must not lose synchronism during any type of fault for a given time period. This withstanding capacity is called low voltage ride through (LVRT. To improve performance during LVRT, enhanced field oriented control (EFOC method is adopted in rotor side converter. This method helps in improving power transfer capability during steady state and better dynamic and transient stability during abnormal conditions. In this technique, rotor flux reference change from synchronous speed to some smaller speed or zero during the fault for injecting current at the rotor slip frequency. In this process, DC-Offset component of flux is controlled beyond decomposing to a lower value during faults and maintaining it. This offset decomposition of flux will be oscillatory in conventional FOC, whereas in EFOC with internal model controller, flux can damp quickly not only for single fault but during multiple faults. This strategy can regulate stator and rotor current waveform to sinusoidal without distortion during and after fault. It has better damped torque oscillations, control in rotor speed and generator flux during and after fault. The fluctuations in DC bus voltage across capacitor are also controlled using proposed EFOC technique. The system performance with under-voltage grid fault of 30% and 60% of the rated voltage occurring at the point of common coupling during 1 to 1.25 and another fault between 1.6 to 1.85 seconds are analyzed using simulation studies.

    Full Text Available Subject of Research. Internal combustion engine as a plant is a highly nonlinear complex system that works mostly in dynamic regimes in the presence of noise and disturbances. A number of engine characteristics and parameters is not known or known approximately due to the complex structure and multimode operating of the engine. In this regard the problem of torque control is not trivial and motivates the use of modern techniques of control theory that give the possibility to overcome the mentioned problems. As a consequence, a relatively simple algorithm of adaptive torque control of injector engine is proposed in the paper. Method. Proposed method is based on nonlinear dynamic model with parametric and functional uncertainties (static characteristics which are suppressed by means of adaptive control algorithm with single adjustable parameter. The algorithm is presented by proportional control law with adjustable feedback gain and provides the exponential convergence of the control error to the neighborhood of zero equilibrium. It is shown that the radius of the neighborhood can be arbitrary reduced by the change of controller design parameters. Main Results. A dynamical nonlinear model of the engine has been designed for the purpose of control synthesis and simulation of the closed-loop system. The parameters and static functions of the model are identified with the use of data aquired during Federal Test Procedure (USA of Chevrolet Tahoe vehicle with eight cylinders 5,7L engine. The algorithm of adaptive torque control is designed, and the properties of the closed-loop system are analyzed with the use of Lyapunov functions approach. The closed-loop system operating is verified by means of simulation in the MatLab/Simulink environment. Simulation results show that the controller provides the boundedness of all signals and convergence of the control error to the neighborhood of zero equilibrium despite significant variations of engine speed.

    Smoking and drinking constitute two risk factors contributing to the rising burden of non-communicable diseases in low- and middle-income countries. Both issues have gained increased international attention, but tobacco control has made more sustained progress in terms of international and domestic policy commitments, resources dedicated to reducing harm, and reduction of tobacco use in many high-income countries. The research presented here offers insights into why risk factors with comparable levels of harm experience different trajectories of global attention. The analysis focuses particular attention on the role of dedicated global health networks composed of individuals and organizations producing research and engaging in advocacy on a given health problem. Variation in issue characteristics and the policy environment shape the opportunities and challenges of global health networks focused on reducing the burden of disease. What sets the tobacco case apart was the ability of tobacco control advocates to create and maintain a consensus on policy solutions, expand their reach in low- and middle-income countries and combine evidence-based research with advocacy reaching beyond the public health-centered focus of the core network. In contrast, a similar network in the alcohol case struggled with expanding its reach and has yet to overcome divisions based on competing problem definitions and solutions to alcohol harm. The tobacco control network evolved from a group of dedicated individuals to a global coalition of membership-based organizations, whereas the alcohol control network remains at the stage of a collection of dedicated and like-minded individuals.

    Transboundary animal diseases pose a serious risk to the world animal agriculture and food security and jeopardize international trade. The world has been facing devastating economic losses from major outbreaks of transboundary animal diseases (TADs) such as foot-and-mouth disease, classical swine fever, rinderpest, peste des petits ruminants (PPR), and Rift Valley fever. Lately the highly pathogenic avian influenza (HPAI) due to H5N1 virus, has become an international crisis as all regions around the world can be considered at risk. In the past decades, public health authorities within industrialized countries have been faced with an increasing number of food safety issues. The situation is equally serious in developing countries. The globalization of food (and feed) trade, facilitated by the liberalization of world trade, while offering many benefits and opportunities, also represents new risks. The GF-TADs Global Secretariat has carried out several regional consultations for the identification of priority diseases and best ways for their administration, prevention and control. In the questionnaires carried out and through the consultative process, it was noted that globally, FMD was ranked as the first and foremost priority. Rift Valley fever, and today highly pathogenic avian influenza, are defined as major animal diseases which also affect human health. PPR and CBPP, a disease which is particularly serious in Africa and finally, African swine fever (ASF) and classical swine fever (CSF) are also regionally recognised as top priorities on which the Framework is determined to work. The FAO philosophy--shared by the OIE--embraces the need to prevent and control TADs and emerging diseases at their source, which is most of the time in developing countries. Regional and international approaches have to be followed, and the FAO and OIE GF-TADs initiative provides the appropriate concepts and objectives as well as an organizational framework to link international and

    2017-07-01

    Aim: Since a system of internal control comprises five inter-related elements, while also taking into consideration that management is ultimately responsible for the internal control in their respective business entities, which is greatly influenced by their managerial conduct, this research study placed focus on determining the relationship which exist between the managerial conduct and the internal control activities evident in South African SMMEs. Setting: This study was conducted in the Cape Metropole, South Africa by obtaining responses from 240 stakeholders of SMMEs: 120 members of management and 120 employees. Methods: In order to achieve the latter, quantitative data were collected through a questionnaire and analysed accordingly through both descriptive statistics and inferential statistics. Results: From the results, a very weak negative statistically significant relationship was identified between the managerial conduct and the internal control activities evident in South African SMMEs. Conclusion: Essentially, management and employees should revisit the internal control activities evident in their respective SMMEs through placing emphasis on those internal control activities which can be built on their control environment.

  2. Engineering the internal structure of magnetic silica nanoparticles by thermal control

    KAUST Repository

    Song, Hyon Min

    2014-09-30

    Calcination of hydrated iron salts in the pores of both spherical and rod-shaped mesoporous silica nanoparticles (NPs) changes the internal structure from an ordered 2D hexagonal structure into a smaller number of large voids in the particles with sizes ranging from large hollow cores down to ten nanometer voids. The voids only form when the heating rate is rapid at a rate of 30 °C min-1. The sizes of the voids are controlled reproducibly by the final calcination temperature; as the temperature is decreased the number of voids decreases as their size increases. The phase of the iron oxide NPs is α-Fe2O3 when annealed at 500 °C, and Fe3O4 when annealed at lower temperatures. The water molecules in the hydrated iron (III) chloride precursor salts appear to play important roles by hydrolyzing Si-O-Si bonding, and the resulting silanol is mobile enough to affect the reconstruction into the framed hollow structures at high temperature. Along with hexahydrates, trivalent Fe3+ ions are assumed to contribute to the structure disruption of mesoporous silica by replacing tetrahedral Si4+ ions and making Fe-O-Si bonding. Volume fraction tomography images generated from transmission electron microscopy (TEM) images enable precise visualization of the structures. These results provide a controllable method of engineering the internal shapes in silica matrices containing superparamagnetic NPs.

    Full Text Available This paper compares and contrasts a number of international approaches to the hydraulic control of surface water runoff from new development and redevelopment, known as sustainable drainage systems (SuDS or low impact development (LID. The paper provides a commentary on the progress and current status of national standards for SuDS in the UK to control the frequency, flow rate and volume of runoff from both frequent and extreme rainfall events, and the best practice design criteria presented in the revised UK CIRIA SuDS Manual, published in November 2015. The paper then compares these design criteria and standards with those developed and applied in China, USA, France and Germany and also looks at the drivers behind their development. The benefits of these different approaches are assessed in the context of flood risk mitigation, climate resilience and wider environmental protection objectives, including water quality, morphology and ecology. The paper also reviews the design approaches promoted by the new SuDS Manual and internationally for delivering additional benefits for urban spaces (such as recreation, visual character, education and economic growth through multi-functional urban design.

    Scaffolding makes it feasible to create organic-polymer monoliths in large confinements, such as wide-bore columns. By creating the scaffold from a metal good heat conductivity inside the column is obtained, which renders the relatively large columns (comparable with 4.6 mm i.d.) suitable for application under ultra-high-pressure LC conditions. It was anticipated that the metal scaffold would allow accurate control of the temperature within the columns, but the temperature profiles within the columns could not be characterized using the previously available small-internal-diameter scaffolded columns. In the current study the internal diameter of the scaffolded columns was increased up to square conduits of 4×4 mm. Prior to the formation of the stationary phase the heating efficiency in the empty scaffolded conduits was addressed. The performance of stationary phases created in the large scaffolds was investigated using the kinetic performance approach and the results were compared to those of the previous studies. Finally, scaffolded columns were tested under ultra-high-pressure LC conditions, where good temperature control is essential. Copyright © 2015 Elsevier B.V. All rights reserved.

    The WHO Executive Board revised the guidance that governs the procedures for the WHO review of psychoactive substances for international drug control in 2010. To meet the standards defined in these guidelines, the current evaluation methodology at WHO must be an evidence-based assessment. We describe the history of substance evaluation from 1912 to the present and the development of the evaluation methods over time including a description of the current assessment system, using reports from WHO and its predecessor, the League of Nations. Furthermore, we describe the current review system. We found that some substances under international control were never reviewed; other substances were reviewed decades ago. We argue that assessments do not have unlimited validity, and therefore, substances need to be re-assessed periodically, as already recommended by the Expert Committee on Drug Dependence in 1982. We propose that the evaluation time be shortened; that the influence of the route of administration and/or dosage form of the preparation is considered in the evaluation; and we recommend studying national and regional assessment systems and adopting their best practices. With this article, we make a case for the inclusion of systematic review and other methods of comprehensive analysis of substance evaluation to arrive at a process of equal rigour and quality as already applied by WHO for the development of treatment guidelines.

    In most highly industrialized countries of the world information plays major role in anti-nuclear campaign. Information and discussions on nuclear power need critical and objective analysis before the structured information presentation to the public to avoid bias anti-nuclear information on one side and neglect of great risk in nuclear power. This research is developing a computer-based information system for the control of nuclear power at international level. The system is to provide easy and fast information highways for the followings: (1) Low Regulatory dose and activity limit as level of high danger for individuals and public. (2) Provision of relevant technical or scientific education among the information carriers in the nuclear power countries. The research is on fact oriented investigation about radioactivity. It also deals with fact oriented education about nuclear accidents and safety. A standard procedure for dissemination of latest findings using technical and scientific experts in nuclear technology is developed. The information highway clearly analyzes the factual information about radiation risk and nuclear energy. Radiation cannot be removed from our environment. The necessity of radiation utilizations defines nuclear energy as two-edge sword. It is therefore, possible to use computer-based information system in projecting and dissemination of expert knowledge about nuclear technology positively and also to use it in directing the public on the safety and control of the nuclear energy. The computer-based information highway for nuclear energy technology is to assist in scientific research and technological development at international level. (author)

    Stress and burnout are highly prevalent among medical doctors, and are associated with negative consequences for doctors, patients, and organizations. The purpose of the current study was to examine the effectiveness of a mindfulness training intervention in reducing stress and burnout among medical practitioners, by means of a Randomised Controlled Trial design. Participants were 44 intern doctors completing an emergency department rotation in a major Australian hospital. Participants were randomly assigned to either an active control (one hour extra break per week) or the 10-week mindfulness training intervention. Measures of stress and burnout were taken pre-, mid- and post intervention. Participants undergoing the 10-week mindfulness training program reported greater improvements in stress and burnout relative to participants in the control condition. Significant reduction in stress and burnout was observed for participants in the mindfulness condition. No such reductions were observed for participants in the control condition. Mindfulness interventions may provide medical practitioners with skills to effectively manage stress and burnout, thereby reducing their experience of these symptoms. It is likely that doctors would benefit from the inclusion of such a training program as a part of their general medical education.

  12. On Synergistic Integration of Adaptive Dithering Based Internal Model Control for Hysteresis Compensation in Piezoactuated Nanopositioner

    Saikat Kumar Shome

    2015-01-01

    Full Text Available Piezoelectric-stack actuated platforms are very popular in the parlance of nanopositioning with myriad applications like micro/nanofactory, atomic force microscopy, scanning probe microscopy, wafer design, biological cell manipulation, and so forth. Motivated by the necessity to improve trajectory tracking in such applications, this paper addresses the problem of rate dependent hysteretic nonlinearity in piezoelectric actuators (PEA. The classical second order Dahl model for hysteresis encapsulation is introduced first, followed by the identification of parameters through particle swarm optimization. A novel inversion based feedforward mechanism in combination with a feedback compensator is proposed to achieve high-precision tracking wherein the paradoxical concept of noise as a performance enhancer is introduced in the realm of PZAs. Having observed that dither induced stochastic resonance in the presence of periodic forcing reduces tracking error, dither capability is further explored in conjunction with a novel output harmonics based adaptive control scheme. The proposed adaptive controller is then augmented with an internal model control based approach to impart robustness against parametric variations and external disturbances. The proposed control law has been employed to track multifrequency signals with consistent compensation of rate dependent hysteresis of the PEA. The results indicate a greatly improved positioning accuracy along with considerable robustness achieved with the proposed integrated approach even for dual axis tracking applications.

    Research has neglected the potential role of perceived parental control as a moderator between stressful life events (SLEs) and child-internalizing symptoms. Using secondary data from the Early Risers "Skills for Success" Program (August, Realmuto, Hektner, & Bloomquist, 2001), this study examined the impact of perceived parental control on the association between SLEs and child internalizing symptoms in formerly homeless families. The sample consisted of 137 families with 223 children between 4 and 12 years of age (M = 8.1, SD = 2.3) living in supportive housing sites in Minneapolis, Minnesota. Participants completed measures assessing the number of SLEs experienced (e.g., unemployment of parent, death of loved one, serious illness, homelessness), perceived parental control, and child-internalizing symptoms. In this sample, 65% of children (n = 144) experienced at least 1 SLE with an average experience of 2 SLEs (M = 2.0, SD = 1.9, range = 0-7). A regression analysis found that experiencing more SLEs and a perceived absence of parental control over child behavior were positively associated with child-internalizing symptoms. A significant interaction between SLEs and perceived absence of parental control over child behavior in predicting child internalizing symptoms was also found. These findings suggest that children of parents who model appropriate control are more likely to experience fewer internalizing symptoms in response to SLEs.

    The aim of this study was to find out if reactive arthritis was involved in the aetiology of chronic closed lock of the temporomandibular joint (TMJ) by looking for bacterial antigens in the synovial membrane of the TMJ, and by studying the antibody serology and carriage of human leucocyte antigen (HLA) B27 in patients with chronic closed lock. Patients with reciprocal clicking and healthy subjects acted as controls. We studied a total of 43 consecutive patients, 15 with chronic closed lock, 13 with reciprocal clicking, and 15 healthy controls with no internal derangements of the TMJ. Venous blood samples were collected from all subjects for measurement of concentrations of HLA tissue antigen and serology against Chlamydia trachomatis, Yersinia enterocolitica, Salmonella spp., Campylobacter jejuni, and Mycoplasma pneumoniae. Samples of synovial tissue from patients with closed lock and reciprocal clicking were obtained during discectomy and divided into two pieces, the first of which was tested by strand displacement amplification for the presence of C trachomatis, and the second of which was analysed for the presence of species-specific bacterial DNA using 16s rRNA pan-polymerase chain reaction (PCR). There were no significant differences between the groups in the incidence of antibodies against M pneumoniae, Salmonella spp. or Y enterocolitica. No patient had antibodies towards C trachomatis or C jejuni. We found no bacterial DNA in the synovial fluid from any patient. The HLA B27 antigen was present in 2/15 subjects in both the closed lock and control groups, and none in the reciprocal clicking group. In conclusion, reactive arthritis does not seem to be the mechanism of internal derangement of the TMJ. Copyright © 2015. Published by Elsevier Ltd.

    Full Text Available During pregnancy, many women experience sleep problems and anxiety that require treatment. The long-term safety for the child of maternal benzodiazepine (BZD and z-hypnotic use during pregnancy remains controversial.We conducted a cohort and a sibling control study using data from the Norwegian Mother and Child Cohort Study. Data on use of BZD and z-hypnotics, internalizing and externalizing outcomes, and covariates were collected from mothers at gestational weeks 17 and 30 and when children were 0.5, 1.5, and 3 years of age. The total sample consisted of 71,996 children (19,297 siblings at 1.5 years and 55,081 children (13,779 siblings at 3 years. Short-term use was defined as use in one pregnancy period only. Long-term use was defined as use in two or more pregnancy periods. Linear full cohort random-effect and sibling-matched fixed-effect regression models were used to compare internalizing and externalizing behavior in children prenatally exposed compared to those unexposed in the full cohort of pregnancies accounting for family clusters, as well as within sibling clusters comparing pregnancies with discordant exposures. Propensity score (PS adjustment included variables on indication for use (sleep problems, symptoms of anxiety and depression and other potential confounding factors.Long-term prenatal exposure to BZD or z-hypnotics was associated with increased internalizing behavior in crude cohort analyses and at age 1.5 years after PS adjustment in sibling-matched fixed-effect models [β 0.60, 95% confidence interval 0.17-0.95]. Analyses on specific drug groups showed that prenatal exposure to BZD-anxiolytics was associated with increased internalizing problems at both 1.5 years [β 0.25, 0.01-0.49] and 3 years [β 0.26, 0.002-0.52] while exposure to z-hypnotics was not associated with any adverse outcomes after adjustment.The findings suggest a moderate association between BZD-anxiolytic exposure and child internalizing problems that is

    Reliable detection of fluorescence intensity (FI) by flow cytometry (FC) is fundamental. FI depends on instrument settings and sample processing procedures: thus, measurements should be done using internal controls with known FI. Commercially available beads-based standards are expensive, thus reducing their usability in the veterinary practice. Cell subsets with stable mean FI (MFI) within the population have been proposed as acceptable surrogates in human medicine. In veterinary medicine, no data exist about stability of antigen expression among different subjects or upon sample storage. The aim of the present study was to evaluate MFI variability of main lymphocytes antigens among the lymphoid cells within each subject, among different subjects, and upon 24-h storage, in order to identify the antigen most suitable as stable internal control in MFI analyses. Peripheral blood samples from 18 healthy dogs were analysed by FC within 3h from sampling to assess the expression of CD3, CD5, CD4, CD8, CD21 and cyCD79b using conjugated monoclonal antibodies. Analyses were restricted to the lymphoid population. Fluorescent microbeads were added to each tube, and antigen MFI was calculated as Relative Fluorescence Intensity RFI (CD/beads). Fluorescence histogram CV (fhCV) for each CD was regarded as an index of the variability of expression among lymphocytes within each subject (cell-to-cell variability); whereas the CV of RFI was regarded as an index of inter-subjects variability (dog-to-dog variability). In 11 cases, FC analyses were repeated after 24h storage at 4°C and RFI and CVs of fresh and stored samples were compared to assess variability linked to storage. CD4 was identified as the best antigen to be used as an internal control for MFI analyses in canine peripheral blood samples because of low cell-to-cell and dog-to-dog variability, and optimal stability upon 24-h storage. Blood samples from a second group of 21 healthy dogs were labelled only with CD4, in order

    The 1st International Conference on Sensing for Industry, Control, Communication & Security Technologies (ICSICCST-2013), took place in Karachi, Pakistan, from 24-26 June 2013. It was organized by Indus University, Karachi, in collaboration with HEJ Research Institute of Chemistry, University of Karachi, Karachi. More than 80 abstracts were submitted to the conference and were double blind-reviewed by an international scientific committee. The topics of the Conference were: Video, Image & Voice Sensing Sensing for Industry, Environment, and Health Automation and Controls Laser Sensors and Systems Displays for Innovative Applications Emerging Technologies Unmanned, Robotic, and Layered Systems Sensing for Defense, Homeland Security, and Law Enforcement The title of the conference, 'Sensing for Industry, Control, Communication & Security Technologies' is very apt in capturing the main issues facing the industry of Pakistan and the world. We believe the sensing industry, particularly in Pakistan, is currently at a critical juncture of its development. The future of the industry will depend on how the industry players choose to respond to the challenge of global competition and opportunities arising from strong growth in the Asian region for which we are pleased to note that the conference covered a comprehensive spectrum of issues with an international perspective. This will certainly assist industry players to make informed decisions in shaping the future of the industry. The conference gathered qualified researchers from developed countries like USA, UK, Sweden, Saudi Arabia, China, South Korea and Malaysia etc whose expertise resulting from the research can be drawn upon to build an exploitable area of new technology that has potential Defense, Homeland Security, and Military applicability. More than 250 researchers/students attended the event and made the event great success as the turnout was 100%. An exceptional line-up of speakers spoke at the occasion. We want

  1. A Robust Model Predictive Control for efficient thermal management of internal combustion engines

    Highlights: • A Robust Model Predictive Control for ICE thermal management was developed. • The proposed control is effective in decreasing the warm-up time. • The control system reduces coolant flow rate under fully warmed conditions. • The control strategy operates the cooling system around onset of nucleate boiling. • Little on-line computational effort is required. - Abstract: Optimal thermal management of modern internal combustion engines (ICE) is one of the key factors for reducing fuel consumption and CO 2 emissions. These are measured by using standardized driving cycles, like the New European Driving Cycle (NEDC), during which the engine does not reach thermal steady state; engine efficiency and emissions are therefore penalized. Several techniques for improving ICE thermal efficiency were proposed, which range from the use of empirical look-up tables to pulsed pump operation. A systematic approach to the problem is however still missing and this paper aims to bridge this gap. The paper proposes a Robust Model Predictive Control of the coolant flow rate, which makes use of a zero-dimensional model of the cooling system of an ICE. The control methodology incorporates explicitly the model uncertainties and achieves the synthesis of a state-feedback control law that minimizes the “worst case” objective function while taking into account the system constraints, as proposed by Kothare et al. (1996). The proposed control strategy is to adjust the coolant flow rate by means of an electric pump, in order to bring the cooling system to operate around the onset of nucleate boiling: across it during warm-up and above it (nucleate or saturated boiling) under fully warmed conditions. The computationally heavy optimization is carried out off-line, while during the operation of the engine the control parameters are simply picked-up on-line from look-up tables. Owing to the little computational effort required, the resulting control strategy is suitable for

    Full Text Available Abstract Globalization has been accompanied by the rapid spread of infectious diseases, and further strain on working conditions for health workers globally. Post-SARS, Canadian occupational health and infection control researchers got together to study how to better protect health workers, and found that training was indeed perceived as key to a positive safety culture. This led to developing information and communication technology (ICT tools. The research conducted also showed the need for better workplace inspections, so a workplace audit tool was also developed to supplement worker questionnaires and the ICT. When invited to join Ecuadorean colleagues to promote occupational health and infection control, these tools were collectively adapted and improved, including face-to-face as well as on-line problem-based learning scenarios. The South African government then invited the team to work with local colleagues to improve occupational health and infection control, resulting in an improved web-based health information system to track incidents, exposures, and occupational injury and diseases. As the H1N1 pandemic struck, the online infection control course was adapted and translated into Spanish, as was a novel skill-building learning tool that permits health workers to practice selecting personal protective equipment. This tool was originally developed in collaboration with the countries from the Caribbean region and the Pan American Health Organization (PAHO. Research from these experiences led to strengthened focus on building capacity of health and safety committees, and new modules are thus being created, informed by that work. The products developed have been widely heralded as innovative and interactive, leading to their inclusion into “toolkits” used internationally. The tools used in Canada were substantially improved from the collaborative adaptation process for South and Central America and South Africa. This international

    The World Health Organization offers clear guidance on the development of national cancer control programmes based on a country's level of resources, yet the motivation to implement such programmes may be driven by factors other than resources. To compare stakeholder motivation to implement a national liver cancer control programme and assess if variation in motivation was associated with stakeholder characteristics or with national indicators of need and resources. Relevant stakeholders were purposively selected from 13 countries (Australia, China, France, Germany, Italy, Japan, Nigeria, South Korea, Spain, Taiwan, Thailand, Turkey and USA) to participate in a structured survey on liver cancer control. Respondents included 12 individuals working in clinical, 5 in policy and 3 in advocacy roles from each country. Stakeholders' motivation was measured using a scale grounded in expectancy theory and knowledge gained during previous qualitative interviews. Comparisons across countries and respondent characteristics were conducted using hierarchical regression. Country level motivation scores, holding constant individual level covariates, were correlated with indicators of need and resources and tested using Pearson's correlation coefficients. In total, 260 stakeholders, equally drawn from the study countries, completed the survey (45% response rate). At the national level, motivation was highest in Nigeria, Thailand and China (P stakeholders working at the international level relative to the local level (P = 0.017). Motivation was positively associated with a country's relative burden of liver cancer (P = 0.015) and negatively associated with their level of resources (P = 0.018). This study provides the first empirical evidence on the motivation of stakeholders to implement national cancer control programmes. Furthermore, we demonstrate that motivation is more clearly associated with a country's cancer control needs rather than resources. Published by Oxford

    The Mission Operations Directorate (MOD) of the Johnson Space Center is responsible for providing continuous operations support for the International Space Station (ISS). Operations support requires flight controllers who are skilled in team performance as well as the technical operations of the ISS. Space Flight Resource Management (SFRM), a NASA adapted variant of Crew Resource Management (CRM), is the competency model used in the MOD. ISS flight controller certification has evolved to include a balanced focus on development of SFRM and technical expertise. The latest challenge the MOD faces is how to certify an ISS flight controller (operator) to a basic level of effectiveness in 1 year. SFRM training uses a two-pronged approach to expediting operator certification: 1) imbed SFRM skills training into all operator technical training and 2) use senior flight controllers as mentors. This paper focuses on how the MOD uses senior flight controllers as mentors to train SFRM skills. Methods: A mentor works with an operator throughout the training flow. Inserted into the training flow are guided-discussion sessions and on-the-job observation opportunities focusing on specific SFRM skills, including: situational leadership, conflict management, stress management, cross-cultural awareness, self care and team care while on-console, communication, workload management, and situation awareness. The mentor and operator discuss the science and art behind the skills, cultural effects on skills applications, recognition of good and bad skills applications, recognition of how skills application changes subtly in different situations, and individual goals and techniques for improving skills. Discussion: This mentoring program provides an additional means of transferring SFRM knowledge compared to traditional CRM training programs. Our future endeavors in training SFRM skills (as well as other organization s) may benefit from adding team performance skills mentoring. This paper

    The International Space Station (ISS) is an on-orbit platform for science utilization in low Earth orbit with multiple sites for external payloads with exposure to the natural and induced environments. Contamination is one of the induced environments that can impact performance, mission success and science utilization on the vehicle. This paper describes the external contamination control requirements and integration process for externally mounted payloads on the ISS. The external contamination control requirements are summarized and a description of the integration and verification process is detailed to guide payload developers in the certification process of attached payloads on the vehicle. A description of the required data certification deliverables covers the characterization of contamination sources. Such characterization includes identification, usage and operational data for each class of contamination source. Classes of external contamination sources covered are vacuum exposed materials, sources of leakage, vacuum venting and thrusters. ISS system level analyses are conducted by the ISS Space Environments Team to certify compliance with external contamination control requirements. This paper also addresses the ISS induced contamination environment at attached payload sites, both at the requirements level as well as measurements made on ISS.

    The current dual-membrane gas trap is designed to remove non-condensed gases (NCG) from the Internal Thermal Control System (ITCS) coolant on board the International Space Station (ISS). To date it has successfully served its purpose of preventing depriming, overspeed, and shutdown of the ITCS pump. However, contamination in the ITCS coolant has adversely affected the gas venting rate and lifetime of the gas trap, warranting a development effort for a next-generation gas trap. Design goals are to meet or exceed the current requirements to (1) include greater operating ranges and conditions, (2) eliminate reliance on the current hydrophilic tube fabrication process, and (3) increase operational life and tolerance to particulate and microbial growth fouling. In addition, the next generation gas trap will essentially be a 'dropin" design such that no modifications to the ITCS pump package assembly (PPA) will be required, and the implementation of the new design will not affect changes to the ITCS operational conditions, interfaces, or software. This paper will present the initial membrane module design and development work which has included (1) a trade study among several conceptual designs, (2) performance modeling of a hydrophobic-only design, and (3) small-scale development test data for the hydrophobic-only design. Testing has shown that the hydrophobic-only design is capable of performing even better than the current dual-membrane design for both steady-state gas removal and gas slug removal.

  9. The future of the international drug control system and national drug prohibitions.

    2017-09-08

    A major impediment to any nation abandoning the policy of drug prohibition has been the fact that international drug treaties to which the majority of United Nations (UN) member states are signatory prohibit the non-medical use of amphetamines, cannabis, cocaine and heroin. The future of these treaties is now uncertain because of decisions by Uruguay, eight US states and Canada to legalize cannabis use. This paper: (1) provides a brief account of the international drug control treaties; (2) outlines the major criticisms of the treaties; (3) analyses critically proposals for treaty reform; and (4) provides a personal view on policies that nation states could adopt to minimize the harms from the use of cannabis, party drugs and hallucinogens, opioids, stimulants and new psychoactive substances. It is argued that: a major risk of cannabis legalization in the United States is promotion of heavy use and increased harm by a weakly regulated industry; some cautious national experiments with the regulation of party drugs and hallucinogens would be informative; a strong case remains for prohibiting the nonmedical use of opioids while mitigating the adverse effects that this policy has on opioid-dependent people; stimulant legalization will probably increase problem use but prohibition is difficult to enforce, highlighting the urgency of finding better ways to reduce demand for these drugs and respond to problem users; and that it is unclear what the best approach is to reducing possible harms that may arise from the use of new psychoactive substances. © 2017 Society for the Study of Addiction.

  10. A paradigm of international environmental law: the case for controlling the transboundary movements of hazardous wastes.

    Science.gov (United States)

    Asante-Duah, K; Nagy, I V

    2001-06-01

    The production of large quantities of wastes globally has created a commercial activity involving the transfrontier shipments of hazardous wastes, intended to be managed at economically attractive waste-handling facilities located elsewhere. In fact, huge quantities of hazardous wastes apparently travel the world in search of "acceptable" waste management facilities. For instance, within the industrialized countries alone, millions of tonnes of potentially hazardous waste cross national frontiers each year on their way for recycling or to treatment, storage, and disposal facilities (TSDFs) because there is no local disposal capacity for these wastes, or because legal disposal or reuse in a foreign country may be more environmentally sound, or managing the wastes in the foreign country may be less expensive than at home. The cross-boundary traffic in hazardous wastes has lately been under close public scrutiny, however, resulting in the accession of several international agreements and laws to regulate such activities. This paper discusses and analyzes the most significant control measures and major agreements in this new commercial activity involving hazardous wastes. In particular, the discussion recognizes the difficulties with trying to implement the relevant international agreements among countries of vastly different socioeconomic backgrounds. Nonetheless, it is also noted that global environmental agreements will generally be a necessary component of ensuring adequate environmental protection for the world community-and thus a need for the careful implementation of such agreements and regulations.

  11. From SARS to Avian Influenza: The Role of International Factors in China's Approach to Infectious Disease Control.

    Goldizen, Fiona C

    2016-01-01

    Over the past decades global environmental change, globalization, urbanization, and the rise in movement of people have increased the risk for pandemic disease outbreaks. As environmental exposures do not respect state borders, a globalist concept of global health response has developed, which requires transparency and cooperation for coordinated responses to disease outbreaks. Countries that avoid cooperation on health issues for social or political reasons can endanger the global community. The aim of this study was to examine the rapid change in China's infectious disease policy between 2000 and 2013, from actively rejecting the assistance of international health experts during the HIV/AIDS and severe acute respiratory syndrome crises to following best-practice disease response policies and cooperating with international health actors during the 2013 avian influenza outbreak. Using international relations theory, I examined whether international political factors had a major influence on this change. Using the case studies of international reputation, socialization with international organizations, and the securitization of infectious disease, this study examined the influence of international and domestic pressures on Chinese infectious disease policy. Although international relations theory, especially theories popular in global health diplomacy literature, provide valuable insight into the role of international factors and foreign policy interests in China's changing approach to infectious disease control, it cannot provide viable explanations without considering the domestic interests of the Chinese government. Analysis of state responses to infectious disease using international relations theories must consider domestic political factors. Copyright © 2016 The Author. Published by Elsevier Inc.

    When optimizing the performance of complex systems, a logical area for concern is improving the efficiency of useful energy. The energy available for a system to perform work is defined as a system's energy content. Interactions between a system's subsystems and the surrounding environment can be accounted for by understanding various subsystem energy efficiencies. Energy balance of reactants and products, and enthalpies and entropies, can be used to represent a chemical process. Heat transfer energy represents heat loads, and flow energy represents system flows and filters. These elements allow for a system level energy balance. The energy balance equations are developed for the subsystems of the Environmental Control and Life Support (ECLS) system aboard the International Space Station (ISS). The use of these equations with system information would allow for the calculation of the energy efficiency of the system, enabling comparisons of the ISS ECLS system to other systems as well as allows for an integrated systems analysis for system optimization.

    In this note, we evaluate the scope of Dockner and Long's [Journal of Environment Economics and Management 24 (1993) 13] conclusion on the efficiency of the non-cooperative outcome in a differential game of international pollution control. We also complete the study of the different equilibria the differential game can present. Our results show that their conclusion requires that the initial value of the stock of pollution be higher than the Pareto-efficient pollution stock so that the equilibrium path of emissions involves a decreasing stock of pollution. Our results also show that the application of the procedure proposed by Tsutsui and Mino [Journal of Economic Theory 52 (1990) 136] to construct a Markov-perfect equilibrium using non-linear strategies is problematic when the initial pollution stock is lower than the Pareto-efficient pollution stock.

    2009-01-01

    In a context where Russia seems to come back to some key principles which guided its international action since the end of Cold War, and relationships between Russia and the USA have been degraded since the US intervention in Iraq (2003), the author examines whether these new Russian postures also concern strategic disarmament, whether Russia is loosing its interest in traditional arrangements of strategic stability, and what are Moscow's priorities within the perspective of expiry of the START 1 Treaty. Thus, the author discusses the role of nuclear weapons in the Russian defence policy, outlines the paradoxes of Russian negotiation positions in the fields of disarmament and arms control, and highlights indirect approaches adopted by Russia on these issues

    There is evidence that drinking during residential treatment is related to various factors, such as patients' general control beliefs and self-efficacy, as well as to external control of alcohol use by program's staff and situations where there is temptation to drink. As alcohol use during treatment has been shown to be associated with the resumption of alcohol use after discharge from residential treatment, we aimed to investigate how these variables are related to alcohol use during abstinence-oriented residential treatment programs for alcohol use disorders (AUD). In total, 509 patients who entered 1 of 2 residential abstinence-oriented treatment programs for AUD were included in the study. After detoxification, patients completed a standardized diagnostic procedure including interviews and questionnaires. Drinking was assessed by patients' self-report of at least 1 standard drink or by positive breathalyzer testing. The 2 residential programs were categorized as high or low control according to the average number of tests per patient. Regression analysis revealed a significant interaction effect between internal and external control suggesting that patients with high internal locus of control and high frequency of control by staff demonstrated the least alcohol use during treatment (16.7%) while patients with low internal locus of control in programs with low external control were more likely to use alcohol during treatment (45.9%). No effects were found for self-efficacy and temptation. As alcohol use during treatment is most likely associated with poor treatment outcomes, external control may improve treatment outcomes and particularly support patients with low internal locus of control, who show the highest risk for alcohol use during treatment. High external control may complement high internal control to improve alcohol use prevention while in treatment. Copyright © 2015 The Authors.

    Load frequency controller has been designed for reduced order model of single area and two-area reheat hydro-thermal power system through internal model control - proportional integral derivative (IMC-PID) control techniques. The controller design method is based on two degree of freedom (2DOF) internal model control which combines with model order reduction technique. Here, in spite of taking full order system model a reduced order model has been considered for 2DOF-IMC-PID design and the designed controller is directly applied to full order system model. The Logarithmic based model order reduction technique is proposed to reduce the single and two-area high order power systems for the application of controller design.The proposed IMC-PID design of reduced order model achieves good dynamic response and robustness against load disturbance with the original high order system.

    Background: In Self-Determination Theory (SDT), a well-validated macro-theory on human motivation, a distinction is made between internally controlling teaching practices (e.g. guilt-induction and shaming) and externally controlling practices (e.g. threats and punishments, commands). While both practices are said to undermine students' motivation,…

  20. 2nd International external quality control assessment for the molecular diagnosis of dengue infections.

    Directory of Open Access Journals (Sweden)

    Cristina Domingo

    Full Text Available BACKGROUND: Currently dengue viruses (DENV pose an increasing threat to over 2.5 billion people in over 100 tropical and sub-tropical countries worldwide. International air travel is facilitating rapid global movement of DENV, increasing the risk of severe dengue epidemics by introducing different serotypes. Accurate diagnosis is critical for early initiation of preventive measures. Different reverse transcriptase PCR (RT-PCR methods are available, which should be evaluated and standardized. Epidemiological and laboratory-based surveillance is required to monitor and guide dengue prevention and control programmes, i.e., by mosquito control or possible vaccination (as soon as an effective and safe vaccine becomes available. OBJECTIVE: The purpose of the external quality assurance (EQA study described is to assess the efficiency and accuracy of dengue molecular diagnosis methods applied by expert laboratories. STUDY DESIGN: A panel of 12 human plasma samples was distributed and tested for DENV-specific RNA. The panel comprised 9 samples spiked with different DENV serotypes (DENV-1 to DENV-4, including 10-fold dilution series of DENV-1 and DENV-3. Two specificity controls consisted of a sample with a pool of 4 other flaviviruses and a sample with chikungunya virus. A negative control sample was also included. RESULTS: Thirty-seven laboratories (from Europe, Middle East Asia, Asia, the Americas/Caribbean, and Africa participated in this EQA study, and reports including 46 sets of results were returned. Performance among laboratories varied according to methodologies used. Only 5 (10.9% data sets met all criteria with optimal performance, and 4 (8.7% with acceptable performance, while 37 (80.4% reported results showed the need for improvement regarding accomplishment of dengue molecular diagnosis. Failures were mainly due to lack of sensitivity and the presence of false positives. CONCLUSIONS: The EQA provides information on each laboratory

  1. Efficacy of diatomaceous earth to control internal infestations of rice weevil and maize weevil (Coleoptera: Curculionidae).

    Arthur, Frank H; Throne, James E

    2003-04-01

    Densities of 10, 20, and 30 hard red winter wheat kernels, Triticum aestivum L., were infested with different life stages of the rice weevil, Sitophilus oryzae (L.), mixed with 35 g of wheat treated with 300 ppm of the Protect-It (Mississauga, Ontario, Canada) formulation of diatomaceous earth (DE), and held at 22, 27, and 32 degrees C. A similar test was conducted by exposing densities of 6, 12, and 18 corn kernels infested with different life stages of the maize weevil, Sitophilus zeamais Motschulsky, mixed with 30 g of corn, Zea mays L., treated with 300 ppm of DE. Mortality of adults emerging from kernels in wheat treated with DE was always greater than controls, and ranged from 56 to 90% at 22 degrees C and was >90% at 27 and 32 degrees C. In most treatment combinations, exposure to DE suppressed F1 progeny by 60-90% relative to untreated controls. Mortality of adult maize weevils on treated corn held at 22 and 27 degrees C was lower than mortality of rice weevils on wheat, and ranged from 4 to 84%. F1 production was low in corn held at 22 degrees C, and no F1s were produced in either the controls or the treatments at 32 degrees C. In treated corn held at 27 degrees C, exposure to the DE suppressed F1 progeny by approximately 70-80% relative to the untreated controls. Results of this study show that rice weevils and maize weevils emerging from infested kernels as adults are susceptible to DE, and these results are comparable to other studies in which adult weevils were exposed directly on wheat or corn treated with DE. Although adult weevils will be killed by exposure to DE, some oviposition could still occur and progeny suppression may not be complete; however, application of DE to commodities already infested with internal feeders, such as the rice weevil and the maize weevil, could help eliminate or suppress the infestation.

    Gaseous ozone (O3) has potential for control of insects in stored grain. Previous studies have focused on freely exposed insects. Immatures of internal pests, (e.g. Sitophilus spp. and most stages of Rhyzopertha dominica F.) are protected within kernels and probably require higher doses and....../or longer treatment times for full control. A laboratory study determined the doses of ozone necessary for full control of freely exposed and internal stages of eleven stored product pest species. Test insects were three species of Sitophilus, R. dominica, Tribolium confusum Jacquelin du Val, T. castaneum...

    This paper proposes a cascaded control structure and a method of practical application for attitude control of a multi-rotor Unmanned aerial vehicle (UAV). The cascade control, which has tighter control capability than a single-loop control, is rarely used in attitude control of a multi-rotor UAV due to the input-output relation, which is no longer simply a set-point to Euler angle response transfer function of a single-loop PID control, but there are multiply measured signals and interactive control loops that increase the complexity of evaluation in conventional way of design. However, it is proposed in this research a method that can optimize a cascade control with a primary and secondary loops and a PID controller for each loop. An investigation of currently available PID-tuning methods lead to selection of the Simple internal model control (SIMC) method, which is based on the Internal model control (IMC) and direct-synthesis method. Through the analysis and experiments, this research proposes a systematic procedure to implement a cascaded attitude controller, which includes the flight test, system identification and SIMC-based PID-tuning. The proposed method was validated successfully from multiple applications where the application to roll axis lead to a PID-PID cascade control, but the application to yaw axis lead to that of PID-PI.

    To determine the relations between household material hardships and having a low internal locus of control over the prevention of child obesity in low-income Hispanic pregnant women. We performed a cross-sectional analysis of baseline data collected during a third trimester prenatal visit from women participating in the Starting Early Study, a randomized controlled trial to test the efficacy of a primary care-based family-centered early child obesity prevention intervention. Using multiple logistic regression analyses, we determined whether 4 domains of material hardship (food insecurity, difficulty paying bills, housing disrepair, neighborhood stress), considered individually and also cumulatively, were associated with having a low internal locus of control over the prevention of child obesity. The sample included 559 low-income Hispanic pregnant women, with 60% having experienced at least 1 hardship. Food insecurity was independently associated with a low internal locus of control over the prevention of child obesity (adjusted odds ratio, 2.38; 95% confidence interval, 1.50-3.77), controlling for other hardships and confounders. Experiencing a greater number of material hardships was associated in a dose-dependent relationship with an increased odds of having a low internal locus of control. Prenatal material hardships, in particular food insecurity, were associated with having a lower prenatal internal locus of control over the prevention of child obesity. Longitudinal follow-up of this cohort is needed to determine how relations between material hardships and having a low internal locus of control will ultimately affect infant feeding practices and child weight trajectories.

  6. Plasma Physics and Controlled Nuclear Fusion Research 1971. Vol. I. Proceedings of the Fourth International Conference on Plasma Physics and Controlled Nuclear Fusion Research

    International Nuclear Information System (INIS)

    1971-01-01

    The ultimate goal of controlled nuclear fusion research is to make a new energy source available to mankind, a source that will be virtually unlimited and that gives promise of being environmentally cleaner than the sources currently exploited. This goal has stimulated research in plasma physics over the past two decades, leading to significant advances in the understanding of matter in its most common state as well as to progress in the confinement and heating of plasma. An indication of this progress is that in several countries considerable effort is being devoted to design studies of fusion reactors and to the technological problems that will be encountered in realizing these reactors. This range of research, from plasma physics to fusion reactor engineering, is shown in the present three-volume publication of the Proceedings of the Fourth Conference on Plasma Physics and Controlled Nuclear Fusion Research. The Conference was sponsored by the International Atomic Energy Agency and was held in Madison, Wisconsin, USA from 17 to 23 June 1971. The Conference was attended by over 500 scientists from 24 countries and 3 international organizations, and 143 papers were presented. These papers are published here in the original language; English translations of the Russian papers will be published in a Special Supplement to the journal Nuclear Fusion. The series of conferences on Plasma Physics and Controlled Nuclear Fusion Research has become a major international forum for the presentation and discussion of results in this important and challenging field. In addition to sponsoring these conferences, the International Atomic Energy Agency supports controlled nuclear fusion research by publishing the journal Nuclear Fusion, and has recently established an International Fusion Research Council. The primary aim of this Council, which had its first meeting in conjunction with the Madison Conference, is to promote international co-operation in controlled nuclear fusion

  7. An Internal Data Non-hiding Type Real-time Kernel and its Application to the Mechatronics Controller

    Science.gov (United States)

    Yoshida, Toshio

    For the mechatronics equipment controller that controls robots and machine tools, high-speed motion control processing is essential. The software system of the controller like other embedded systems is composed of three layers software such as real-time kernel layer, middleware layer, and application software layer on the dedicated hardware. The application layer in the top layer is composed of many numbers of tasks, and application function of the system is realized by the cooperation between these tasks. In this paper we propose an internal data non-hiding type real-time kernel in which customizing the task control is possible only by change in the program code of the task side without any changes in the program code of real-time kernel. It is necessary to reduce the overhead caused by the real-time kernel task control for the speed-up of the motion control of the mechatronics equipment. For this, customizing the task control function is needed. We developed internal data non-cryptic type real-time kernel ZRK to evaluate this method, and applied to the control of the multi system automatic lathe. The effect of the speed-up of the task cooperation processing was able to be confirmed by combined task control processing on the task side program code using an internal data non-hiding type real-time kernel ZRK.

    The regulation of khat, one of the most recent psychoactive drugs to become a globally traded commodity, remains hotly contested within different producer and consumer countries. As regimes vary, it has been possible to compare khat policies in Africa, Europe and North America from different disciplinary perspectives. Field research was conducted in East Africa and Europe, using a combination of semistructured interviews, participant observation and the analysis of trade statistics. The research established the significance of khat for rural producers, regional economies, as a tax base and source of foreign exchange. At the same time, khat as a psychoactive substance is associated with health and public safety problems that in turn are met with often ill-informed legislative responses. Bans have in turn lead to the criminalisation of users and sellers and illegal drug markets. The empirical work from Africa provides a strong argument for promoting evidence-based approaches to khat regulation, harnessing the positive aspects of the khat economy to develop a control model that incorporates the voices and respects the needs of rural producers. Ultimately, the framework for khat may provide both a model and an opportunity for revising the international treaties governing the control of other plant psychoactive-based substances.

    2003-01-01

    In JET advanced tokamak research mainly focuses on plasmas with internal transport barriers (ITBs), generated by modifications of the current profile. The formerly developed optimised shear regime with low magnetic shear in the plasma center has been extended to deeply reversed magnetic shear configurations. High fusion performance with wide ITBs has been obtained transiently in deeply reversed magnetic shear configuration: H IPB98(y,2) ∼1.9, β N =2.4 at I p =2.5MA. At somewhat reduced performance electron and ion ITBs have been sustained in full current drive operation with 1MA of bootstrap current: H IPB98(y,2) ∼1, β N =1.7 at I p =2.0MA. The ITBs have been maintained up to 11s. This duration, much larger than the energy confinement time (37 times larger), is already approaching a current resistive time. New real-time measurements and feedback control algorithms have been developed and implemented in JET for successfully controlling the ITB dynamics and the current density profile in the highly non-inductive regime.

    Full Text Available Business combinations under common control in International Financial Reporting Standards – is authoritative accounting guidance needed? The purpose of the article is to answer the question if a separate standard (IFRS is needed for business combinations under common control (BCUCC, which are not governed by any IFRS as the moment. In such cases, the approach resulting from IAS 8 should apply to them, which allows the use of national regulations to account for BCUCC. The authoress shortly described the theoretical issues related to the subject and presented the results of empirical research that verified the practical aspects of the problem. The research methodology involves a literature and legal act analysis, content analysis of financial statements, as well as deductive and inductive reasoning. On the basis of the gathered data the authoress concluded that even the existence of necessary regulations in national GAAPs does not guarantee that all the requirements related to the qualitative characteristics of the reported information are met and, as such, the main objectives for which IFRS were developed may not be met. As such, the authoritative guidance proves necessary. Very little research on the subject was published, thus, this paper may provide some additional guidance as to what issues related to BCUCC should receive particular attention.

  11. The Impact of Arms Limitation Agreements and Export Control Regulations of International Commercial Launch Activities

    Freeland, Steven

    2002-01-01

    The commercial launch industry is by its very nature a global sector dominated by multinationals that operate across national boundaries. Since the end of the Cold War, new launch operators have become increasingly reliant on existing space and propulsion technology from Russia and other former constituent republics of the Soviet Union. With this in mind, the impact of export controls imposed by various countries under various internationally agreements, especially those of Australia, Russia and the United States, has become an increasingly important factor in the day-to-day operation of commercial launch operators. This is particularly true for launch operators utilising converted ballistic missiles as launch vehicles, as they have to consider also the impact of arms reduction treaties, such as START, on their launch operations. This paper explores the legal and administrative operations of the START and export control regimes operated by Russia and the United States, as well as emerging launching States such as Australia, and how they impact on the logistical operations of domestic or multinational commercial launch operators.

  12. Vitamin A deficiency disorders: international efforts to control a preventable "pox".

    Underwood, Barbara A

    2004-01-01

    Visual symptoms (night blindness) of vitamin A deficiency (VAD) were among the earliest diet-related deficiencies documented. Knowledge of vitamin A chemistry, metabolism and deficiency consequences accrued rapidly during the first eight decades of the 20th century. A series of disorders were described in animals, including impaired growth, reproduction, epithelial integrity, and disease resistance that were relieved by consumption of both animal and plant sources of the vitamin. Identification of the intestinal beta-carotene cleavage enzyme in the laboratory of James Allen Olson was seminal to understanding the mechanism for formation of vitamin A from ingested carotenoids. WHO's 1990 estimate of about 40 million children annually with clinical eye signs of VAD was revised upward to 140-250 million at risk of vitamin A deficiency disorders (VADD) when epidemiological and clinical trials demonstrated morbidity and mortality risk even in the absence of ocular signs. Alternative methods for VAD status assessment and more reliable analytical techniques were developed, several in Dr. Olson's laboratory. The last decade has seen global progress in VADD control by expanding distribution of medicinal supplements, fortification of foods and dietary diversification through horticulture and education programs. Experience shows that achievements gained through narrowly focused interventions are fragile and vulnerable to national political and economic instability. Contextually relevant, community-centered strategies that improve household food and nutrition security and self-reliance are critical to sustaining international efforts to control the VADD "pox."

    Digitoxin induces apoptosis in different human malignant cell lines in vitro. In this paper we investigated if patients taking digitoxin for cardiac disease have a different cancer incidence compared to the general population. Computer stored data on digitoxin concentrations in plasma from 9271 patients with cardiac disease were used to define a user population. Age and sex matched controls from the Norwegian Cancer Registry were used to calculate the number of expected cancer cases. The population on digitoxin showed a higher incidence of cancer compared to the control population. However, an additional analysis showed that the population on digitoxin had a general increased risk of cancer already, before the start on digitoxin. Leukemia/lymphoma were the cancer types which stood out with the highest risk in the digitoxin population before starting on digitoxin. This indicates that yet unknown risk factors exist for cardiovascular disease and lymphoproliferative cancer. An internal dose-response analysis revealed a relationship between high plasma concentration of digitoxin and a lower risk for leukemia/lymphoma and for cancer of the kidney/urinary tract. Morbidity and mortality are high in the population on digitoxin, due to high age and cardiac disease.These factors disturb efforts to isolate an eventual anticancer effect of digitoxin in this setting. Still, the results may indicate an anticancer effect of digitoxin for leukemia/lymphoma and kidney/urinary tract cancers. Prospective clinical cancer trials have to be done to find out if digitoxin and other cardiac glycosides are useful as anticancer agents

    2003-01-01

    The purpose of the EXPRESS (Expedite the PRocessing of Experiments to Space Station) rack project is to provide a set of predefined interfaces for scientific payloads which allow rapid integration into a payload rack on International Space Station (ISS). VxWorks' was selected as the operating system for the rack and payload resource controller, primarily based on the proliferation of VME (Versa Module Eurocard) products. These products provide needed flexibility for future hardware upgrades to meet everchanging science research rack configuration requirements. On the International Space Station, there are multiple science research rack configurations, including: 1) Human Research Facility (HRF); 2) EXPRESS ARIS (Active Rack Isolation System); 3) WORF (Window Observational Research Facility); and 4) HHR (Habitat Holding Rack). The RIC (Rack Interface Controller) connects payloads to the ISS bus architecture for data transfer between the payload and ground control. The RIC is a general purpose embedded computer which supports multiple communication protocols, including fiber optic communication buses, Ethernet buses, EIA-422, Mil-Std-1553 buses, SMPTE (Society Motion Picture Television Engineers)-170M video, and audio interfaces to payloads and the ISS. As a cost saving and software reliability strategy, the Boeing Payload Software Organization developed reusable common software where appropriate. These reusable modules included a set of low-level driver software interfaces to 1553B. RS232, RS422, Ethernet buses, HRDL (High Rate Data Link), video switch functionality, telemetry processing, and executive software hosted on the FUC computer. These drivers formed the basis for software development of the HRF, EXPRESS, EXPRESS ARIS, WORF, and HHR RIC executable modules. The reusable RIC common software has provided extensive benefits, including: 1) Significant reduction in development flow time; 2) Minimal rework and maintenance; 3) Improved reliability; and 4) Overall

    2014-01-01

    Full Text Available We set information disclosure of internal control as a starting point to explore the relationship between the quality of internal control and accounting conservatism, and then adopt the entropy testing model to calculate the index of the internal control quality with the sample data of Chinese listed companies in financial industry from 2007–2011. Regression results show that earnings conservatism exists. The stronger the internal control is, the higher the accounting conservatism can be. Companies which have enhanced their internal control are more conservative, and these results make no difference with other industries.

    2001-01-01

    Substantial progress has been made towards both understanding and control of internal transport barriers (ITBs) on DIII-D, resulting in the discovery of a new sustained high performance operating mode termed the Quiescent Double-Barrier (QDB) regime. The QDB regime combines core transport barriers with a quiescent, ELM-free H-mode edge (termed QH-mode), giving rise to separate (double) core and edge transport barriers. The core and edge barriers are mutually compatible and do not merge, resulting in broad core profiles with an edge pedestal. The QH-mode edge is characterized by ELM-free behavior with continuous multiharmonic MHD activity in the pedestal region, and has provided density and impurity control for 3.5 s (>20 τ E ) with divertor pumping. QDB plasmas are long-pulse high-performance candidates, having maintained a β N H 89 product of 7 for 5 energy confinement times (T i ≤16 keV, β N ≤2.9, H 89 ≤2.4, τ E ≤150 ms, DD neutron rate S n ≤4x10 15 s -1 ). The QDB regime has only been obtained in counter-NBI discharges (injection anti-parallel to plasma current) with divertor pumping. Other results include successful expansion of the ITB radius using (separately) both impurity injection and counter-NBI, and the formation of ITBs in the electron thermal channel using both ECH and strong negative central shear (NCS) at high power. These results are interpreted within a theoretical framework in which turbulence suppression is the key to ITB formation and control, and a decrease in core turbulence is observed in all cases of ITB formation.

It is used as a teaching aid during WHC lessons for both ISS crew and flight controllers. ISS flight control documentation is used to support all aspects of ISS mission operations. The Quick Look Database and Consolidated Tool Page are imagery-based references used in real-time to help the Operations Support Officer (OSO) find data faster and improve discussions with the Flight Director and Capsule Communicator (CAPCOM). A Quick Look page was created for the Permanent Multipurpose Module (PMM) by locating photos of the module interior, labeling specific hardware, and organizing them in schematic form to match the layout of the PMM interior. A Tool Page was created for the Maintenance Work Area (MWA) by gathering images, detailed drawings, safety information, procedures, certifications, demonstration videos, and general facts of each MWA component and displaying them in an easily accessible and consistent format. Participation in ISS mechanisms and maintenance lessons, mission simulation On-the-Job Training (OJT), and real-time flight OJT was used as an opportunity to train for day-to-day operations as an OSO, as well as learn how to effectively respond to failures and emergencies during mission simulations and real-time flight operations.

    Full Text Available Real-time polymerase chain reaction (RT-PCR enables effective and sensitive screening for infectious risk in the field of blood safety. However, when using RT-PCR to detect bacterial contamination, several intractable points must be considered, one of which is the lack of appropriate quality control. In this study, we developed a simplified RT-PCR assay in which the same primer set and two distinct probes were used to detect both, an internal reference control and the target in a reaction. The copy number of the internal reference control represents the positive detection limit of the assay; therefore, when the threshold-cycle value of the target is less than or equal to that of the internal reference control, the result obtained for the target can be considered to be a true positive. When human gDNA was spiked with Escherichia coli gDNA and the detection limit for the internal reference control was set to five copies, the measured detection limit for E. coli gDNA was two copies. The internal reference control duplex RT-PCR assay showed high efficiency (0.91-1.02, high linearity (R2 > 0.99, and good reproducibility in intra- and inter-assay comparisons. Lastly, when human platelet-rich plasma samples were spiked with E. coli or other bacterial species, all species were detected efficiently, and the results of a two-sample pooled t test showed that the limit of detection for E. coli was 1 cfu/mL. Here, we present a synthetic internal reference control molecule and a new statistical method for improving the reliability of RT-PCR assays when screening for bacterial contamination in blood products.

    We synthesized octa-arginine conjugates of DNA-binding agents (bisbenzamidine, acridine and Thiazole Orange) and demonstrated that their DNA binding and cell internalization can be inhibited by appending a (negatively charged) oligoglutamic tail through a photolabile linker. UV irradiation released the parent conjugates, thus restoring cell internalization and biological activity. Assays with zebrafish embryos demonstrates the potential of this prodrug strategy for controlling in vivo cytotoxicity. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Mobile phone use has increased dramatically in many countries since its introduction in the early-to-mid 1980's. The expanding use of this technology has been accompanied by concerns about health and safety. In the late 1990's, several expert groups critically reviewed the evidence on health effects of low-level exposure to radiofrequency (RF) electromagnetic fields emitted by mobile phones, and recommended research into the possible adverse health effects of mobile telephone use. As a result, the International Agency for Research on Cancer (IARC) coordinated a feasibility study in 1998 and 1999, which concluded that an international study of the relationship between mobile phone use and brain tumour risk would be feasible and informative. Interphone was therefore initiated as an international set of case-control studies focussing on four types of tumours in tissues that most absorb RF energy emitted by mobile phones: tumours of the brain (glioma and meningioma), acoustic nerve (schwannoma) and parotid gland. The objective was to determine whether mobile phone use increases the risk of these tumours and, specifically, whether RF energy emitted by mobile phones is carcinogenic. The methods, results and conclusions are provided here and thus this report to the UICC marks the completion of the Interphone Study. A major strength of the Interphone study was the conduct of several validation studies to assist in assessing the study's strengths and limitations and inform the researchers about possible shortcomings when interpreting the main results. In this context Interphone is quite unique among epidemiological studies on health effects of mobile phone use and the insight obtained from the validation studies is also informative when it comes to evaluating other studies in this field. The comprehensive validation studies are a unique feature of Interphone, enabling the researchers to quantify problems persistent in this type of observational studies and to assist in the

    analysis. During the International Space Station's (ISS's) on-orbit assembly and outfitting, a series of engineering analyses were conducted to evaluate how effective the passive TCC methods were relative to providing adequate operational margin for the active TCC equipment's capabilities aboard the ISS. These analyses were based on habitable module and cargo vehicle offgassing test results. The offgassing test for a fully assembled module or cargo vehicle is an important preflight spacecraft evaluation method that has been used successfully during all crewed spacecraft programs to provide insight into how effectively the passive contamination control methods limit the equipment offgassing component of the overall trace contaminant generation load. The progression of TCC assessments beginning in 1998 with the ISS's first habitable element launch and continuing through the final pressurized element's arrival in 2010 are presented. Early cargo vehicle flight assessments between 2008 and 2011 are also presented as well as a discussion on predictive methods for assessing cargo via a purely analytical technique. The technical approach for TCC employed during this 13-year period successfully maintained the cabin atmospheric quality within specified parameters during the technically challenging ISS assembly and outfitting stages. The following narrative provides details on the important role of spacecraft offgassing testing, trace contaminant performance requirements, and flight rules for achieving the ultimate result-a cabin environment that enables people to live and work safely in space.

    Full Text Available The article gives reasons for the need to develop the mechanism and tools of performance evaluation based on the implementation of specific management functions, as well as the integrated evaluation of the effectiveness of internal corporate controls. It presents the approbation of the proposed assessment methodology on the example of JSC “SUEK-Kuzbass”. The monitoring role as one of the functions of management is constantly increasing in the market economy. The participation of Russian companies in the international economy requires the organisation of internal company control. Moreover, with the enacting of the Law “On Accountings» № 402-FZ, for the majority of economic agents the organising of internal control became mandatory. Thus, the internal control means the process carried out by the Board of Directors and other staff of the organisation aimed at providing reasonable assurance that the objectives of the organisation such as ensuring the effectiveness and efficiency of operations, reliability of financial reporting and compliance with the legislation in force will be achieved.

    are strong proponents of its use and others have said that they are only prepared to accept its application if safety controls are substantially improved. All affiliates of the ICFTU are convinced that energy policy options must be widened through increased research and development of new and renewable sources and through extensive energy conservation measures. The environmental impact of all methods of energy generation must be assessed on the basis of the public availability of all relevant information. It is in this context, that whatever their views about the desirability or otherwise of nuclear power, all ICFTU affiliates recognise the immediate need to assure the highest possible level of safety for all nuclear plants and activities everywhere - for example to deal with radioactive wastes created over the last 30 years. Even if some countries opt out of nuclear power it is likely that many others will be committed to it for many years. Given the widespread effects of a catastrophic failure anywhere in the world we must therefore all be concerned to strengthen the international safety regime. Because of their historic role in campaigning for health and safety at work, unions are well placed to exercise an independent watchdog role - making use of the knowledge and skills of their members in the nuclear industry - and are also able to speak on behalf of a large membership which is representative representative of the wide public concern about nuclear safety. Immediately following the Chernobyl disaster, the ICFTU Executive Board adopted a resolution (reproduced as Appendix 2 to this document) calling for immediate steps to tighten up nuclear safety. In the light of subsequent developments, the Confederation has now given further detailed consideration to the whole question of nuclear safety and has decided to publish this report which contains detailed proposals for tighter international control of nuclear energy via the International Atomic Energy Agency (IAEA

    Prevention and treatment of the addictions are key public health priorities in modern society. In medical practice, in relation to the biochemical processes, mapping the addiction-prone personality traits, like external/internal locus of control are getting more and more attention. Individuals with high level on internal locus of control, for example, tend to take care of their health behavior; the lack of it, on the other hand, may worsen the effectiveness of stress release which may increase the likelihood of turning to substance use. The main goal of the present study was to investigate the relationship between adolescent substance use (both lifetime prevalence and the actual substance user status) and external/internal locus of control). The data collection of the questionnaire survey was going on among 656 high school students in Szeged (age range between 14-21 years, mean = 16.5 years, S.D. = 1.5 years of age, 49.1% of the sample was female). Associations between indicators of substance use (as dependent variables) and scale points of external/internal locus of control (as independent variables) were assessed using odds ratios calculated by logistic regression analyses, whereas gender was used as a controlling variable. Among boys, scale points of external, among girls, those of internal locus of control showed higher values. External locus of control increased, whereas internal locus of control decreased the risk of substance use, however, the relative role of external/internal locus of control was different according to the type of substance use and the prevalence values. In terms of smoking, lifetime prevalence, whereas in terms of marijuana use, the actual user status was influenced. In addition, while the latter one was also affected by gender, it did not play a role at all in the previous one. All these findings suggest that behavioral control may play a particularly important role in prevention of adolescent substance use. For developing this, methods

    The International Space Station (ISS) operates in the F2 region of Earth's ionosphere, orbiting at altitudes ranging from 350 to 450 km at an inclination of 51.6 degrees. The relatively dense, cool F2 ionospheric plasma suppresses surface charging processes much of the time, and the flux of relativistic electrons is low enough to preclude deep dielectric charging processes. The most important spacecraft charging processes in the ISS orbital environment are: 1) ISS electrical power system interactions with the F2 plasma, 2) magnetic induction processes resulting from flight through the geomagnetic field and, 3) charging processes that result from interaction with auroral electrons at high latitude. Recently, the continuing review and evaluation of putative ISS charging hazards required by the ISS Program Office revealed that ISS charging could produce an electrical shock hazard to the ISS crew during extravehicular activity (EVA). ISS charging risks are being evaluated in an ongoing measurement and analysis campaign. The results of ISS charging measurements are combined with a recently developed model of ISS charging (the Plasma Interaction Model) and an exhaustive analysis of historical ionospheric variability data (ISS Ionospheric Specification) to evaluate ISS charging risks using Probabilistic Risk Assessment (PRA) methods. The PRA combines estimates of the frequency of occurrence and severity of the charging hazards with estimates of the reliability of various hazard controls systems, as required by NASA s safety and risk management programs, to enable design and selection of a hazard control approach that minimizes overall programmatic and personnel risk. The PRA provides a quantitative methodology for incorporating the results of the ISS charging measurement and analysis campaigns into the necessary hazard reports, EVA procedures, and ISS flight rules required for operating ISS in a safe and productive manner.

    Irrational prescribing is a habit which is difficult to cure. However, prevention is possible and for this reason the WHO Action Programme on Essential Drugs aims to improve the teaching of pharmacotherapy to medical students. The impact of a short problem-based training course in pharmacotherapy, using a WHO manual on the principles of rational prescribing, was measured in an international multi-centre randomised controlled study of 219 undergraduate medical students in Groningen (Netherlands), Kathmandu (Nepal), Lagos (Nigeria), Newcastle (Australia), New Delhi (India), San Francisco (USA), and Yogyakarta (Japan). The manual and the course presented the students, who were about to enter the clinical phase of their studies, with a normative model for pharmacotherapeutic reasoning in which they were taught to generate a "standard" pharmacotherapeutic approach to common disorders, resulting in a set of first-choice drugs called P(ersonal)-drugs. The students were then taught how to apply this set of P-drugs to specific patient problems on the symptomatic treatment of pain, using a six-step problem-solving routine. The impact of the course was measured by tests before training, immediately after, and six months later. After the course, students from the study group performed significantly better than controls in all patient problems presented (p students not only remembered how to solve old problems, but they could also apply their skills to new problems. Both retention and transfer effect were maintained at least six months after the training session in all seven medical schools. In view of the impossibility of teaching students all basic knowledge on the thousands of drugs available, this approach seems to be an efficient way of teaching rational prescribing. However, the method should be accompanied by a change in teaching methods away from the habit of transferring knowledge about the drugs towards problem-based teaching of therapeutic reasoning.

    The overall program objective is to develop and evaluate environmentally benign agents or products that are effective in the prevention, inhibition, and mitigation of microbially influenced corrosion (MIC) in the internal surfaces of metallic natural gas pipelines. The goal is to develop one or more environmentally benign (a.k.a. ''green'') products that can be applied to maintain the structure and dependability of the natural gas infrastructure. Various chemicals that inhibit the growth and/or the metabolism of corrosion-associated microbes such as sulfate reducing bacteria, denitrifying bacteria, and methanogenic bacteria were evaluated to determine their ability to inhibit corrosion in experiments utilizing pure and mixed bacterial cultures, and planktonic cultures as well as mature biofilms. Planktonic cultures are easier to inhibit than mature biofilms but several compounds were shown to be effective in decreasing the amount of metal corrosion. Of the compounds tested hexane extracts of Capsicum pepper plants and molybdate were the most effective inhibitors of sulfate reducing bacteria, bismuth nitrate was the most effective inhibitor of nitrate reducing bacteria, and 4-((pyridine-2-yl)methylamino)benzoic acid (PMBA) was the most effective inhibitor of methanogenic bacteria. All of these compounds were demonstrated to minimize corrosion due to MIC, at least in some circumstances. The results obtained in this project are consistent with the hypothesis that any compound that disrupts the metabolism of any of the major microbial groups present in corrosion-associated biofilms shows promise in limiting the amount/rate of corrosion. This approach of controlling MIC by controlling the metabolism of biofilms is more environmentally benign than the current approach involving the use of potent biocides, and warrants further investigation.

    Full Text Available Prevention and earlier detection of fraudulent financial reporting must start with the entity that prepares financial reports. Thus the first focus of the Sarbannes-Oxley Act’s recommendations is the public company. These recommendations, taken together, will improve a company's overall financial reporting process and increase the likelihood of preventing fraudulent financial reporting and detecting it earlier when it occurs. For some companies, implementing these recommendations will require little or even no change from current practices; for other companies, it will mean adding or improving a recommended practice. Whether it means adding or improving a practice, the benefits justify the costs. The Sarbanes-Oxley Act is a direct response to the recent scandals in the US corporate world. Governance, compliance, risks and internal controls are mounting concerns for almost all organizations. As the numbers of rules, regulations and contractual obligations steadily rise, management is growing more and more concerned about their exposure on day-to-day operational decisions!

    Internal quality control (IQC) is a critical component of laboratory quality management, and IQC products can determine the reliability of testing results. In China, given the fact that most blood transfusion compatibility laboratories do not employ IQC products or do so minimally, there is a lack of uniform and standardized IQC methods. To explore the reliability of IQC products and methods, we studied 697 results from IQC samples in our laboratory from 2012 to 2014. The results showed that the sensitivity and specificity of the IQCs in anti-B testing were 100% and 99.7%, respectively. The sensitivity and specificity of the IQCs in forward blood typing, anti-A testing, irregular antibody screening, and cross-matching were all 100%. The reliability analysis indicated that 97% of anti-B testing results were at a 99% confidence level, and 99.9% of forward blood typing, anti-A testing, irregular antibody screening, and cross-matching results were at a 99% confidence level. Therefore, our IQC products and methods are highly sensitive, specific, and reliable. Our study paves the way for the establishment of a uniform and standardized IQC method for pre-transfusion compatibility testing in China and other parts of the world.

    In the current study, we examined the expression level of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) protein in a number of organisms and the stability of GAPDH under various conditions. Our results revealed that GAPDH is present in multiple Escherichia coli strains, the yeast strain GS115, Caenorhabditis elegans, rat PC12 cells, and both mouse and rat brain. Furthermore, GAPDH was stably expressed under different concentrations of inducer and at different times of induction in E. coli (BL21) cells and yeast GS115 cells. Stable expression of GAPDH protein was also observed in C.elegans and PC12 cells that were treated with different concentrations of paraquat or sodium sulfite, respectively. In addition, we were able to detect and identify the endogenous gapA protein in E.coli via immunoprecipitation and MALDI-TOF-MS analysis. Endogenous gapA protein and exogenously expressed (subcloned) GAPDH proteins were detected in E. coli BL21 but not for gapC. With the exception of gapC in E. coli, the various isoforms of GAPDH possessed enzymatic activity. Finally, sequence analysis revealed that the GAPDH proteins were 76% identical, with the exception of E. coli gapC. Taken together, our results indicate that GAPDH could be universally used as an internal control for the Western blot analysis of prokaryotic and eukaryotic samples. Crown Copyright © 2012.

    2009-03-01

    Internal quality control (IQC) and external quality assurance (EQA) are distinct processes that contribute to ensure the overall quality (i.e., correctness) of laboratory test procedures. This review summarizes the current position of IQC and EQA in platelet function testing. These processes are in their infancy for these tests, despite the many years in which these tests have been performed within diagnostic hemostasis laboratories. This is understandable, due to the many challenges imposed by the requirements of the tests themselves and of the IQC and EQA processes, namely the regular availability, and ongoing supply and transport, of fresh blood containing functional platelets for testing within a very short time frame. Nevertheless, recently published studies have shown that IQC and EQA are both feasible for platelet function testing, although these processes have typically been undertaken in some modified form compared with other tests of hemostasis. Several EQA organizations are currently involved in providing support to laboratories that perform platelet function testing. Initiatives to date include cross-laboratory challenges for PFA-100 testing, several patterns of practice surveys, and several other EQA challenges related to dense granules and light transmission aggregometry. EQA organizations may be best placed to act as facilitators to the process of improving diagnostic testing for platelet function, which supplements the role of expert organizations.

    This survey was initiated to obtain knowledge on the current situation of internal quality control (IQC) practice for tumour markers (TMs) in China. Additionally, we tried to acquire the most appropriate quality specifications. This survey was a current status survey. The IQC information had been collected via online questionnaires. All of 1821 clinical laboratories which participated in the 2016 TMs external quality assessment (EQA) programme had been enrolled. The imprecision evaluation criteria were the minimal, desirable, and optimal allowable imprecisions based on biological variations, and 1/3 total allowable error (TEa) and 1/4 TEa. A total of 1628 laboratories answered the questionnaires (89%). The coefficients of variation (CVs) of the IQC of participant laboratories varied greatly from 1% (5 th percentile) to 13% (95 th percentile). More than 82% (82 - 91%) of participant laboratories two types of CVs met 1/3 TEa except for CA 19-9. The percentiles of current CVs were smaller than cumulative CVs. A number of 1240 laboratories (76%) reported their principles and systems used. The electrochemiluminescence was the most used principle (45%) and had the smallest CVs. The performance of laboratories for TMs IQC has yet to be improved. On the basis of the obtained results, 1/3 TEa would be realistic and attainable quality specification for TMs IQC for clinical laboratories in China.

    Post-ruptured intracranial aneurysm geometry models have been widely used in computational fluid dynamic studies to assess hemodynamic parameters associated with aneurysm rupture. However, their results may not be valid due to the morphological changes of the aneurysm after rupture. Our aim was to identify the hemodynamic features of aneurysms prior to rupture in comparison with unruptured aneurysms. We retrospectively identified three large unruptured internal carotid artery (ICA) aneurysms (pre-ruptured group) with adequate image quality just before rupture. Matched with the same location and similar size, eight unruptured aneurysms (unruptured group) were selected as controls during the same time period. Flow simulations for these aneurysms were performed to compare differences in hemodynamics. Compared with unruptured aneurysms, pre-ruptured aneurysms had a significantly more irregular aneurysm shape, a higher aspect ratio, and lower aneurysm averaged wall shear stress (WSS) (p=0.024, p=0.048, and p=0.048, respectively). Although pre-ruptured aneurysms had a lower low WSS area and higher Oscillatory Shear Index, these were not statistically significant. For large unruptured ICA aneurysms, low WSS, higher aspect ratio, and irregular shape were indicators of fatal rupture. Early treatment for such lesions with flow diverter and coils may be the best therapeutic option. Published by the BMJ Publishing Group Limited.

    Berg, E S; Skaug, K

    2003-10-01

    A system intended for whole process quality assurance of nucleic acid amplification assays was developed based on the use of liposomes as cell-mimicking vehicles for the internal control, allowing introduction of the internal control directly into the crude biological specimens. By the proof of principle testing, the Roche Cobas Amplicor CT assay was chosen as model system and the Roche CT/NG Internal Control was thus loaded into the liposomes. The liposome/DNA particles were spiked into a Chlamydia trachomatis-positive urine specimen. A quantitative "in-house" duplex real-time C. trachomatis PCR assay showed that liposomes having Blue Dextran 2000 polysaccharide co-entrapped were the most suited particles as they were efficiently deposited by the centrifugation carried out according to the Roche urine specimen preparation procedure. Furthermore, it was demonstrated that the liposome/DNA particles might be used for whole process quality assurance of Amplicor assay without major modifications of the assay protocol. An additional feature of the use of these liposomes was that the pellet became blue coloured and that might facilitate a thorough removal of the urine supernatant without increasing the risk of disturbance of the pellet. Principally, the liposome/internal control system is versatile and seems to be applicable for whole process quality control of amplification-based assays for detection of various pathogens.

    To review international policies to control expenditure on pharmaceuticals by influencing the behaviour of patients and providers and regulating the pharmaceutical industry. Systematic review of experimental and quasi-experimental studies. Published studies were identified with an electronic search strategy using MEDLINE and EMBASE from 1980 to May 2012. Studies were eligible if they assessed the effect of policies aimed at influencing the behaviour of patients and providers, and regulating the pharmaceutical industry. Outcome measures included pharmaceutical expenditure, prices or utilization; other resource use relating to pharmaceuticals; and health outcomes and patients' or providers' behaviour relating to pharmaceutical use. Quality assessment criteria for each study design were developed based on the standard criteria recommended by the Cochrane Effective Practice and Organisation of Care (EPOC) group. The review includes studies based on randomized controlled trials and rigorous quasi-experimental designs (interrupted time-series and controlled before-and-after studies). Studies were excluded if they were conducted within a single hospital or practice; related to pharmaceutical care services or disease management; had less than 6 months of follow-up period (or less than 12 months overall for interrupted time series); if data in controlled before-and-after studies were not collected contemporaneously or if no rationale was stated for the choice of control group; or if relevant and interpretable data were not presented. A total of 255 studies met the inclusion criteria for this review. The majority of the studies relating to patients evaluated cost sharing interventions such as user charges (52 studies). User charges do reduce utilization of pharmaceuticals, and reduce public expenditure by shifting costs to patients. But they reduce the use of essential as well as non-essential drugs, and without adequate exemptions they affect vulnerable groups

    NASA is investigating a range of future human spaceflight missions, including both Mars-distance and Near Earth Object (NEO) targets. Of significant importance for these missions is the balance between crew autonomy and vehicle automation. As distance from Earth results in increasing communication delays, future crews need both the capability and authority to independently make decisions. However, small crews cannot take on all functions performed by ground today, and so vehicles must be more automated to reduce the crew workload for such missions. NASA's Advanced Exploration Systems Program funded Autonomous Mission Operations (AMO) project conducted an autonomous command and control experiment on-board the International Space Station that demonstrated single action intelligent procedures for crew command and control. The target problem was to enable crew initialization of a facility class rack with power and thermal interfaces, and involving core and payload command and telemetry processing, without support from ground controllers. This autonomous operations capability is enabling in scenarios such as initialization of a medical facility to respond to a crew medical emergency, and representative of other spacecraft autonomy challenges. The experiment was conducted using the Expedite the Processing of Experiments for Space Station (EXPRESS) rack 7, which was located in the Port 2 location within the U.S Laboratory onboard the International Space Station (ISS). Activation and deactivation of this facility is time consuming and operationally intensive, requiring coordination of three flight control positions, 47 nominal steps, 57 commands, 276 telemetry checks, and coordination of multiple ISS systems (both core and payload). Utilization of Draper Laboratory's Timeliner software, deployed on-board the ISS within the Command and Control (C&C) computers and the Payload computers, allowed development of the automated procedures specific to ISS without having to certify

    A technique to achieve output tracking for nonminimum phase linear systems with non-hyperbolic and near non-hyperbolic internal dynamics is presented. This approach integrates stable inversion techniques, that achieve exact-tracking, with approximation techniques, that modify the internal dynamics to achieve desirable performance. Such modification of the internal dynamics is used (1) to remove non-hyperbolicity which an obstruction to applying stable inversion techniques and (2) to reduce large pre-actuation time needed to apply stable inversion for near non-hyperbolic cases. The method is applied to an example helicopter hover control problem with near non-hyperbolic internal dynamic for illustrating the trade-off between exact tracking and reduction of pre-actuation time.

    The recurrence rate after primary anterior shoulder dislocation is high, especially in young, active individuals. Recent studies have suggested external rotation immobilization as a method to reduce the rate of recurrent shoulder dislocation in comparison to traditional sling immobilization. To assess and summarize evidence from randomized controlled trials on the effect of internal rotation versus external rotation immobilization on the rate of recurrence after primary anterior shoulder dislocation. Meta-analysis. PubMed, MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and abstracts from recent proceedings were searched for eligible studies. Two reviewers selected studies for inclusion, assessed methodological quality, and extracted data. Six randomized controlled trials (632 patients) were included in this review. Demographic and prognostic variables measured at baseline were similar in the pooled groups. The average age was 30.1 years in the pooled external rotation group and 30.3 years in the pooled internal rotation group. Two studies found that external rotation immobilization reduced the rate of recurrence after initial anterior shoulder dislocation compared with conventional internal rotation immobilization, whereas 4 studies failed to find a significant difference between the 2 groups. This meta-analysis suggested no overall significant difference in the rate of recurrence among patients treated with internal rotation versus external rotation immobilization (risk ratio, 0.69; 95% CI, 0.42-1.14; P = .15). There was no significant difference in the rate of compliance between internal and external rotation immobilization (P = .43). The Western Ontario Shoulder Instability Index scores were pooled across 3 studies, and there was no significant difference between the 2 groups (P = .54). Immobilization in external rotation is not significantly more effective in reducing the recurrence rate after primary anterior shoulder dislocation than

    Faced with a difficult business environment in the United States and the falling demand for cigarettes in industrialized countries, multinational tobacco companies have been competing fiercely to expand their sales in developing countries. Because of the worldwide threat posed by smoking to health and the emphasis being placed by international tobacco companies on marketing in developing countries, an international regulatory strategy, such as the WHO proposed Framework Convention on Tobacco Control, is needed. This review describes from a public health perspective the possible scope and key considerations of protocols that should be included in the convention. The key international areas that should be considered in tobacco control are: prices, smuggling; tax-free tobacco products; advertising and sponsorship; the Internet; testing methods; package design and labelling; agriculture; and information sharing.

    The IAEA, in its publication RS-G-1.2, proposes individual control of workers occupationally exposed with risk of internal exposure when the potential exposure provided by incorporation leads to a value of annual committed effective dose equal to or greater than 1 mSv. Because the radionuclide 131 I is the most important to control internal exposure in Nuclear Medicine Services, it is evaluated if the surface contamination monitors, commonly used in nuclear medicine centers of Argentina, would implement individual control of internal exposure to 131 I. Selected detectors were calibrated with a dummy neck and thyroid with calibrated sources of 131 I and 133 Ba reference. For each detector is was estimated the detection efficiency for 131 I and its detection limit. Each instrument was evaluated for the lowest effective dose possible to detect compromised by individual routine monitoring with different measurement intervals . We analyzed the response of each team for determining conditions that may be effective for the control of internal exposure of 131 I. Finally , we conclude that the daily individual monitoring surface contamination detectors available in the Nuclear Medicine Services is feasible to implement and ensures detection of significant additions of 131 I

    To investigate authors' adherence to the CONSORT reporting guideline for randomized controlled trials (RCTs) in the sub-specialty Female Pelvic Medicine and to detect any changes in adherence between the years 2008 and 2013. Bibliometric study. We included Female Pelvic Medicine RCTs published in 2008 and 2012-2013 in 10 journals. Full-text versions of RCTs for the inclusion of the CONSORT checklist items Randomization, Allocation, Blinding, and Participants' flowchart were screened. Each CONSORT checklist item was categorized for each included RCT as either "complete reporting", "insufficient reporting", "no reporting," or "not applicable". We screened the "Instructions to authors" for the requirement to adhere to CONSORT. We included 94 Female Pelvic Medicine RCTs for analysis. Most RCTs in 2008, 2012, and 2013 were published by IUJ (n =n39), followed by NAU (n = 13), GREEN (n = 12), European Urology (n = 8), FMPRS (n = 6), AJOG (n = 4), Urology (n = 3), NEJM (n = 3), Lancet (n = 1), and BJOG (n = 1). Proportion of RCTs in the category "complete reporting" comparing 2008 and 2013 was (47 and 70%) for Randomization, (18 and 45%) for Allocation, and (29 and 52%) for Blinding; a flowchart was presented in (71 and 91%). The increase was not statistically significant in any of the investigated CONSORT items. Complete reporting of Female Pelvic Medicine RCTs has increased between 2008 and 2013. However, there are still a relevant number of published RCTs, which do not fulfill these criteria. Reporting according to the CONSORT guidelines should be further encouraged to improve internal validity of Female Pelvic Medicine RCTs. Neurourol.

    The measurement of volatile organic compound (VOC) emissions from building products and materials by manufacturers and testing laboratories, and the use of the test results for labeling programs, continue to expand. One issue that hinders wide acceptance for chamber product testing is the lack of a reference material to validate test chamber performance. To meet this need, the National Institute of Standards and Technology (NIST) and Virginia Tech (VT) have developed a prototype reference material that emits a single VOC similar to the emissions of a diffusion-controlled building product source with a dynamic emissions profile. The prototype material has undergone extensive testing at NIST and a pilot interlaboratory study (ILS) with four laboratories. The next development step is an evaluation of the prototype source in multiple-sized chambers of 14 laboratories in seven countries. Each laboratory was provided duplicate specimens and a test protocol. Study results identified significant issues related to the need to store the source at a subzero Celsius temperature until tested and possible inconsistencies in large chambers. For laboratories using a small chamber and meeting all the test method criteria, the results were very encouraging with relative standard deviations ranging from 5% to 10% across the laboratories. Currently, the chamber performance of laboratories conducting product VOC emissions testing is assessed through interlaboratory studies (ILS) using a source with an unknown emission rate. As a result, laboratory proficiency can only be based on the mean and standard deviation of emission rates measured by the participating ILS laboratories. A reference material with a known emission rate has the potential to provide an independent assessment of laboratory performance as well as improve the quality of interlaboratory studies. Several international laboratories with different chamber testing systems demonstrated the ability to measure the emission rate

    Nearly 400 years after Galileo Galilei of Florence was arraigned and convicted of suspected heresy by the ten member Congregation of the Holy Office (Inquisition), the International Narcotic Control Board (INCB) is similarly inserting itself into matters pertaining to innovations in healthcare and the public health response to addiction throughout the world. Like that earlier Inquisition of 1633 that convicted Galileo of heresy for holding that the sun is the centre of the universe with the earth revolving around it (in contradiction to church doctrine of the time) the INCB and its thirteen-member panel, now rails against any evidence out of sync with the established doctrine of the war on drugs--particularly those innovations in public health called harm reduction. The latest healthcare and harm reduction practices to attract the ire of the INCB Inquisition are elements of Canada's most effective and innovative measures to minimize the harms of drugs in Vancouver--supervised injection facilities and, recently, the potential establishment of supervised inhalation rooms--along with the long established practice of providing safer mouthpieces for pulmonary inhalation in British Columbia. This is particularly significant as it comes in the midst of a crucial battle between municipal and provincial authorities in BC with the federal government in Ottawa, which seems determined to undermine all the most effective HR programs that are the result of years of steady local and governmental support in Vancouver and now threatens to derail all these programs and spread doubt about their usefulness despite the overwhelmingly positive findings of serous research.

  20. Damage Control Plan for International Space Station Recharge Tank Assembly Composite Overwrapped Pressure Vessel

    2011-01-01

    As NASA has retired the Space Shuttle Program, a new method of transporting compressed gaseous nitrogen and oxygen needed to be created for delivery of these crucial life support resources to the International Space Station (ISS). One of the methods selected by NASA includes the use of highly pressurized, unprotected Recharge Tank Assemblies (RTAs) utilizing Composite Overwrapped Pressure Vessels (COPVs). A COPV consists of a thin liner wrapped with a fiber composite and resin or epoxy. It is typically lighter weight than an all metal pressure vessel of similar volume and therefore provides a higher-efficiency means for gas storage. However COPVs are known to be susceptible to damage resulting from handling, tool drop impacts, or impacts from other objects. As a result, a comprehensive Damage Control Plan has been established to mitigate damage to the RTA COPV throughout its life cycle. The DCP is intended to evaluate and mitigate defined threats during manufacturing, shipping and handling, test, assembly level integration, shipment while pressurized, launch vehicle integration and mission operations by defining credible threats and methods for preventing potential damage while still maintaining the primary goal of resupplying ISS gas resources. A comprehensive threat assessment is performed to identify all threats posed to the COPV during the different phases of its lifecycle. The threat assessment is then used as the basis for creating a series of general inspection, surveillance and reporting requirements which apply across all phases of the COPV's life, targeted requirements only applicable to specific work phases and a series of training courses for both ground personnel and crew aboard the ISS. A particularly important area of emphasis deals with creating DCP requirements for a highly pressurized, large and unprotected RTA COPV for use during Inter Vehicular Activities (IVA) operations in the micro gravity environment while supplying pressurized gas to the

    Background Decades of research have produced overwhelming evidence that tobacco taxes reduce tobacco use and increase government tax revenue. The magnitude and effectiveness of taxes at reducing tobacco use provide an incentive for tobacco users, manufacturers and others, most notably criminal networks, to devise ways to avoid or evade tobacco taxes. Consequently, tobacco tax avoidance and tax evasion can reduce the public health and fiscal benefit of tobacco taxes. Objectives First, this study aims to document, using data from the International Tobacco Control Policy Evaluation Project (ITC), levels and trends in cigarette users’ tax avoidance and tax evasion behaviour in a sample of sixteen low-, middle- and high-income countries. Second, this study explores factors associated with cigarette tax avoidance and evasion. Methods We use data from ITC surveys conducted in 16 countries to estimate the extent and the type of cigarette tax avoidance/evasion between countries and across time. We use self-reported information about the source of a smoker’s last purchase of cigarettes or self-reported packaging information, or similar information gathered by the interviewers during face-to-face interviews to measure tax avoidance/evasion behaviours. We use generalized estimating equations (GEE) to explore individual-level factors that may affect the likelihood of cigarette tax avoidance or evasion in Canada, United States, United Kingdom and France. Findings We find prevalence estimates of cigarette tax avoidance/evasion vary substantially between countries and across time. In Canada, France and the United Kingdom, more than 10% of smokers report last purchasing cigarettes from low or untaxed sources while in Malaysia, some prevalence estimates suggest substantial cigarette tax avoidance/evasion. We also find important associations between household income and education and the likelihood to engage in tax avoidance/evasion. These associations, however, vary both in

    Full Text Available Abstract Background At the time of feasibility work and final design of the trial there was no randomised control trial evidence for the long-term risks and benefits of hormone replacement therapy. Observational studies had suggested that long term use of estrogen was likely to be associated, amongst other things, with reduced risks of osteoporosis and ischaemic heart disease and increased risks of breast and endometrial cancer. Concomitant use of progestogens had been shown to protect against endometrial cancer, but there were few data showing how progestogen might affect estrogen actions on other conditions. Disease specific risks from observational studies suggested that, overall, long-term HRT was likely to be beneficial. Several studies showed that mortality from all causes was lower in HRT users than in non-users. Some secondary cardiovascular prevention trials were ongoing but evidence was also required for a range of outcomes in healthy women. The WISDOM trial was designed to compare combined estrogen and progestogen versus placebo, and estrogen alone versus combined estrogen and progestogen. During the development of WISDOM the Women's Health Initiative trial was designed, funded and started in the US. Design Randomised, placebo, controlled, trial. Methods The trial was set in general practices in the UK (384, Australia (94, and New Zealand (24. In these practices 284175 women aged 50–69 years were registered with 226282 potentially eligible. We sought to randomise 22300 postmenopausal women aged 50 – 69 and treat for ten years.

CSDS-2005 featured the latest research in nonlinear dynamics concentrating on the theory of control and synchronization of complex systems and its applications in different areas of science and engineering, including optics, electronics, mechanics, chemistry, medicine, economy, communication, etc. The conference brought together leading researchers, both theoreticians and experimentalists, from different fields of science and provided an excellent opportunity for sharing ideas and problems among specialists in controlling dynamical systems and synchronization. The meeting served a dual purpose: to expose the scientific community to the cutting edge of forefront research done by leaders in this area from as many as 25 countries and to attract the attention of Mexican researchers to this field of science. These proceedings are intended to be a record of this conference and to serve as a reference for future research which the conference hopes to have initiated. After the pioneering work on controlling chaos of E Ott, C Grebogi and J Yorke appeared in Physical Review Letters in 1990, the number of works on this topic grew tremendously. Our extensive bibliographic search among 110 peer reviewed journals yielded more than 1500 papers on controlling chaos and more than 2500 on synchronization of chaotic systems published during the last decade. The numbers of publications are still at their peaks that began to saturate, in 1998 and 2003, respectively. It is my pleasure to acknowledge the contribution of the program and organizing committees, the funding agencies and cooperating

    The ultimate goal of controlled nuclear fusion research is to make a new energy source available to mankind, a source that will be virtually unlimited and that gives promise of being environmentally cleaner than the sources currently exploited. This goal has stimulated research in plasma physics over the past two decades, leading to significant advances in the understanding of matter in its most common state as well as to progress in the confinement and heating of plasma. An indication of this progress is that in several countries considerable effort is being devoted to design studies of fusion reactors and to the technological problems that will be encountered in realizing these reactors. This range of research, from plasma physics to fusion reactor engineering, is shown in the present three-volume publication of the Proceedings of the Fourth Conference on Plasma Physics and Controlled Nuclear Fusion Research. The Conference was sponsored by the International Atomic Energy Agency and was held in Madison, Wisconsin, USA from 17 to 23 June 1971. The enthusiastic co-operation of the University of Wisconsin and of the United States Atomic Energy Commission in the organization of the Conference is gratefully acknowledged. The Conference was attended by over 500 scientists from 24 countries and 3 international organizations, and 143 papers were presented. These papers are published here in the original language; English translations of the Russian papers will be published in a Special Supplement to the journal Nuclear Fusion. The series of conferences on Plasma Physics and Controlled Nuclear Fusion Research has become a major international forum for the presentation and discussion of results in this important and challenging field. In addition to sponsoring these conferences, the International Atomic Energy Agency supports controlled nuclear fusion research by publishing the journal Nuclear Fusion, and has recently established an International Fusion Research Council

  8. Low doses of ionizing radiation: Biological effects and regulatory control. Invited papers and discussions. Proceedings of an international conference

    The levels and biological effects resulting from exposure to ionizing radiation are continuously reviewed by the United Nations Committee on the Effects of Atomic Radiation (UNSCEAR). Since its creation in 1928, the International Commission on Radiological Protection (ICRP) has issued recommendations on protection against ionizing radiation. The UNSCEAR estimates and the ICRP recommendations have served as the basis for national and international safety standards on radiation safety, including those developed by the International Atomic Energy Agency (IAEA) and the World Health Organization (WHO). Concerning health effects of low doses of ionizing radiation, the international standards are based on the plausible assumption that, above the unavoidable background radiation dose, the probability of effects increases linearly with dose, i.e. on a 'linear, no threshold' (LNT) assumption. However, in recent years the biological estimates of health effects of low doses of ionizing radiation and the regulatory approach to the control of low level radiation exposure have been much debated. To foster information exchange on the relevant issues, an International Conference on Low Doses of Ionizing Radiation: Biological Effects and Regulatory Control, jointly sponsored by the IAEA and WHO in co-operation with UNSCEAR, was held from 17-21 November 1997 at Seville, Spain. These Proceedings contain the invited special reports, keynote papers, summaries of discussions, session summaries and addresses presented at the opening and closing of the Conference

    Early age shrinkage of cementitious systems can result in an increased potential for cracking which can lead to a reduction in service life. Early age shrinkage cracking can be particularly problematic for high strength concretes, which are often specified due to their high strength and low permeability. However, these high strength concretes frequently exhibit a reduction in the internal relative humidity (RH) due to the hydration reaction (chemical shrinkage) and self-desiccation which results in a bulk shrinkage, termed autogenous shrinkage, which is substantial at early ages. Due to the low permeability of these concretes, standard external curing is not always efficient in addressing this reduction in internal RH since the penetration of water can be limited. Internal curing has been developed to reduce autogenous shrinkage. Internally cured mixtures use internal reservoirs filled with fluid (generally water) that release this fluid at appropriate times to counteract the effects of self-desiccation thereby maintaining a high internal RH. Internally cured concrete is frequently produced in North America using pre-wetted lightweight aggregate. One important aspect associated with preparing quality internally cured concrete is being able to determine the absorbed moisture and surface moisture associated with the lightweight aggregate which enables aggregate moisture corrections to be made for the concrete mixture. This thesis represents work performed to develop a test method using a centrifuge to determine the moisture state of pre-wetted fine lightweight aggregate. The results of the test method are then used in a series of worksheets that were developed to assist field technicians when performing the tests and applying the results to a mixture design. Additionally, research was performed on superabsorbent polymers to assess their ability to be used as an internal curing reservoir.

    Full Text Available Evaluation of the reliability of enterprises engaged in the foreign economic activity and simplifying of Customs procedures have become a relevant issue in the context of globalization. The capabilities and preferences of the “Authorized Economic Operator” status are the cause of a new challenge for managers of enterprises – creation of an internal control system to ensure a systematic monitoring of the conditions of Customs compliance standards of reliability and safety, which would allow identifying risks of loss of the “Authorized Economic Operator” status. The purpose of the scientific paper is to improve the internal control system of an enterprise engaged in foreign economic activity in the process of obtaining and saving the “Authorized Economic Operator” status in accordance with the international Custom requirements for safety and reliability. Methodology. The research is based on the methods of logical and analytical modelling of the impact assessment of individual factors on the value of the generalization indicator. The results are tested on the internal accounting data of the existing machine-building enterprises. Results. The paper shows the results of adapting the concept of COSO to the system of internal control of the foreign economic activity of the enterprise in the process of obtaining or retaining the “Authorized Economic Operator” status. The internal control system within the concept of COSO should ensure the achievement of the objectives – operations, reporting, and compliance. The criteria for estimating the objective “compliance” for an enterprise engaged in foreign economic activity can be an integral indicator of compliance. Value/originality. It is suggested to perform internal control of an enterprise’s compliance with Customs requirements based on the analysis of deviations of the compliance integral indicator. Practical implications. The result of control is to perform a steady in

    The use of corrosion inhibitors is spread out in oil and gas industry and is the most common methodology to control pipeline internal corrosion. However, their effectiveness depends on the pipeline material, inhibitor composition, flow type and scale characteristics. When a pipeline has heavy scale deposits, thick bacterial biofilm, or oxygen contamination, the corrosion control via filmic inhibitors is not effective. So, the only way to control internal corrosion of an oil pipeline is to primary identifies the corrosive agent and the main corrosion mechanism. The monitoring of the inhibitor efficiency and the determination of minimal residual concentration to prevent corrosion, are also fundamental. In this paper, is presented the criteria used to identify the main corrosion mechanism of oil pipelines, the treatment proposed in each case and the techniques employed in real time corrosion monitoring.

    Full Text Available The valve plays an important part in the industrial automation system. Whether it operates normally or not relates with the quality of the products directly while its faults are relatively common because of bad working conditions. And the internal leakage is one of the common faults. Consequently, this paper sets up the experimental platform to make the valve in different working condition and collect relevant data online. Then, diagnose the internal leakage of the valve by using the grey correlation analysis method. The results show that this method can not only diagnose the internal leakage of valve accurately, but also distinguish fault degree quantitatively.

  14. Control, oversight and related terms in the international guidance on geological disposal of radioactive waste - Review of definitions and use

    International Nuclear Information System (INIS)

    2014-01-01

    This document presents the most complete analysis of the use of the words control, oversight, etc. as used in NEA, IAEA and ICRP literature connected to radioactive waste disposal. It reveals the many different ways the same word, 'control', has been used in international guidance and ambiguities than can arise, especially so for the post-closure phase of the repository. The newly introduced ICRP terminology, namely the use of the words 'oversight' and 'built-in controls', represents a step forward in terminology and resolves the ambiguity

    A flex hose assembly containing aqueous coolant from the International Space Station (ISS) Internal Active Thermal Control System (IATCS) consisting of a 2 foot section of Teflon hose and quick disconnects (QDs) and a Special Performance Checkout Unit (SPCU) heat exchanger containing separate channels of IATCS coolant and iodinated water used to cool spacesuits and Extravehicular Mobility Units (EMUS) were returned for destructive analyses on Shuttle return to flight mission STS-114. The original aqueous IATCS coolant used in Node 1, the Laboratory Module, and the Airlock consisted of water, borate (pH buffer), phosphate (corrosion control), and silver sulfate (microbiological control) at a pH of 9.5 +/- 0.5. Chemical changes occurred after on-orbit implementation including a decrease to pH 8.4 due to the diffusion of carbon dioxide through the Teflon hoses, an increase in nickel ions due to general corrosion of heat exchanger braze coatings, a decrease in phosphate concentration due to precipitation of nickel phosphate, and the rapid disappearance of silver ions due to deposition on hardware surfaces. Also associated with the coolant chemistry changes was an increase in planktonic microorganisms from less than 100 colony forming units (CFU) per 100 ml to approximately 1 million CFU per 100 ml. Attachment and growth of microorganisms to the system surfaces (biofilm) was suspected due to the levels of planktonic microorganisms in the coolant. Biofilms can reduce coolant flow, reduce heat transfer, amplify degradation of system materials initiated by chemical corrosion, and enhance mineral scale formation.

    With the world population attaining the six billion mark, the urgency of increasing quality food production and reducing the spread of diseases transmitted by insects, without affecting our fragile environment, will be of paramount importance. Losses currently experienced in agricultural production, due to insect pests and through diseases transmitted by insect vectors, are very high especially in developing and poor countries. Many insect pests and vectors are of economic importance, and several such as fruit flies, mosquitoes and tsetse flies have attracted international concerns. Most pests are traditionally controlled through heavy reliance on pesticides which can cause environmental pollution, pesticide resistance, and pest resurgence. The control, management or eradication of insect pests and vectors with minimal adverse impact on our food quality, environment, health and well-being should be of great concern to many agriculturists, biological and physical scientists as well as to national and international agencies responsible for pest control. Steps taken by the various concerned agencies to improve and implement the area-wide control will hopefully lead us into the next millennium free from major insect pests and vectors while at the same time protect our precarious global environment. This volume is the culmination of proceedings conducted in two recent international meetings, FAO/IAEA International Conference on Area-Wide Control of Insect Pests, 28 May - 2 June 1998, and the Fifth International Symposium on Fruit Flies of Economic Importance, 1-5 June 1998, held in Penang, Malaysia. Over three hundred papers (both oral contributions and posters) were presented at the two meetings. The manuscripts submitted by authors are divided according to broad topics into eighteen sections originally defined by the organisers as corresponding to the sessions of the meetings. The organisers identified one to several individuals in each of the sessions to deliver an

    Full Text Available Romania, as a European Union member state, has undergone, in recent years, a complex process of reform in all activity fields. This includes the current process of public administration reform, which aims to improve the management, the administrative capacity and the manner in which the entire Romanian public sector is organized. In this study, we intend to portray the manner in which the internal control system and the internal audit structure of a Romanian public entity are shaped into form. For exemplification, we chose the internal audit mission titled “The Accounting System and Its Reliability”. We will identify the risks, we will assess them and we will also propose measures through which the entity’s management may mitigate these risks by correcting registered deviations.
