  1. The Many Meanings of Open Source

    OpenAIRE

    Gacek, Cristina; Arief, Budi

    2004-01-01

    Many software development methodologies are called "open source". However, simply stating that a project is open source doesn't precisely describe the approach used to support the project. A multidisciplinary viewpoint can help determine those characteristics that are common to open source projects and those that vary among projects. These characteristics form the basis for a taxonomy of open source projects that's useful for analyzing and setting up projects. They also provide a starting poi...

    Researchers are skeptical about the role of authoritative sources of information in a constructivist learning environment for fear of usurping students' critical thinking. Taking a social semiotics perspective in this study, authoritative sources are regarded as inscriptions of cultural artifacts, and science learning involves meaning-making of these cultural artifacts. In studying the meaning-making process of a group of students doing problem-based learning (PBL), our findings show that authoritative sources played an important role in deepening and expanding students' scientific knowledge. We also found that constructive use of authoritative sources involves interpretation of meaning in context. This structural coupling of authoritative sources and context for meaningful sense-making has to be taken into consideration in the design of learning environment.

    Full Text Available This study used six toy Chihuahua dogs in relationship. They underwent four 8 week periods differing in type of food (dry, soft, dental diet and preventive means of periodontitis (tooth-brushing and enzymatic chewing strips. The results showed nonsignificant influence of food consistency on dental plaque, calculus and gingivitis scores. Dental diet nonsignificantly decreased dental calculus deposition in comparison to common commercial food. The best results were achieved with toothbrushing. The enzymatic chewing strips significantly decreased dental plaque, calculus and gingivitis scores only on carnassial teeth. These results confirm that there are no absolute preventive measures of periodontitis.

  8. Malicious acts involving radioactive sources: prevention and preparedness for response

    2008-01-01

    Full text: The increasing concern over the malevolent use of radioactive sources and radiological terrorism demands strengthening the preparedness for response to radiological emergencies. In spite of various security measures adopted internationally, availability of orphan sources cannot be completely ruled out. The trends in terrorism also indicates the possibility of various means which may be adopted by terrorists especially if they are aware of the challenges of radioactive contamination in public domain and the capability of 'denial of area' and the fear factor which can be injected during such radiological emergencies. It is to be well understood that whatever measures are taken by some countries in preventing the sources from getting stolen or smuggled in/out of their country are not adequate to eliminate radiological terrorism in a global level unless all nations collectively address and ensure the security of radioactive sources, hence preventing the generation of any orphan sources. While preparedness for response to various radiological emergency scenario have many common factors, the challenges involved in responding to radiological terrorism involves understanding the fear factor due to the presence of radioactive contamination after the blast and thermal effects on the victims and issues like handling of contaminated and seriously injured persons, restriction on the movement of responders and forensic teams in a contaminated field etc. Hence an understanding and anticipation of all possible means of radiological terrorism is very essential to prevent and to reduce the consequences. There are many deterrents, which are to be developed and maintained by all nations collectively which should include intelligence, wide usage of radiation monitors by customs, police and other security agencies, installation of state of the art high sensitive radiation monitors and systems etc to prevent and deter stealing and illicit trafficking of radioactive sources

    2010-01-01

    The purpose of the paper is to discuss means of assisting terminally ill patients in seeking for sources of meaning and hope, alongside the acknowledgment that their lifespan is short.Psycho-spiritual aspects make a substantial component patients suffering from incurable illness have to deal with. Evaluating and mapping the causes and expressions of psychological--spiritual suffering may assist in tailoring appropriate strategies of distress relief. Therefore, interventions should be given in accordance with their specific focus of difficulties, as well as with wishes and needs. Appropriate interventions in palliative psychotherapeutic rapport are inspired by identifying new sources for meaning in current life (sometimes, aided by past experiences or future visions). Reinforcing sources for meaning may attempt in providing patients amongst:--equilibrium, between suffering and sorrow (which sometimes take over the patient's world), and on the other hand, new experiences, sense of satisfaction and fulfillment. Individual's acknowledgment that he is not completely withdrawn from the circle of life, and yet significance and fulfillment in life still exists. For a holistic meaning ? centered intervention it is advisable to simultaneously integrate two central axes: the existential analysis, inspired by concepts driven from Frenkl's Logotherapy, such as freedom of choice, personal responsibility, inner truth, hope and transcendentalism; the operative axis, enhancing meaning and hope by assisting patient's wishes come true. Patients are aware, many times, that those wishes may be their last one, therefore perceive their fulfillment as crucial for their sense of meaning. Moreover, those wishes may elevate patient and family's spirit and reduce risk of demoralization. Whereas existential--spiritual interventions are recommended to be given by qualified professional therapists, the operation of fulfilling wishes is feasible by everyone, from family members to multi

    2014-12-01

    Full Text Available The aim of the paper is to identify corruption prevention tools and new ways of approaching them. The research question is how society coped with corruption in an era heavily marked by the media and the internet. The hypothesis that led us to the study was that new strategies of communication are necessary and based on them the civil society capacity to monitor and evaluate can be improved. The new approaches highlighted new entities, such as education, NGOs, media and internet, or new concepts, such as prevention, local strategies, audit, image and identity. Among these new entities involved in prevention, education should act as a real inner actor to change.

    2017-01-01

    The goal of this study was to describe the relative utility of the terms "means safety" versus "means restriction" in counseling individuals to limit their access to firearms in the context of a mock suicide risk assessment. Overall, 370 participants were randomized to read a vignette depicting a clinical scenario in which managing firearm ownership and access was discussed either using the term "means safety" or "means restriction." Participants rated the term "means safety" as significantly more acceptable and preferable than "means restriction." Participants randomized to the "means safety" condition reported greater intentions to adhere to clinicians' recommendations to limit access to a firearm for safety purposes (F[1,367] = 7.393, p = .007, [Formula: see text]). The term "means safety" may be more advantageous than "means restriction" when discussing firearm ownership and access in clinical settings and public health-oriented suicide prevention efforts.

    The Goiania radiation accident triggered a reassessment of radiation safety systems. From a legal point of view, the course of events indicates that there were deficiencies either in the existing legal framework or in the implementation of that framework. Proposals to avoid similar accidents in the future are discussed, stressing the need for a sound legal regime and a close co-operation between state authorities and users of radioactive sources. In particular, the importance is underscored of the human factor in achieving a high level of radiation safety. (author)

  19. Agronomic evaluation of guano sources by means of isotope techniques

    International Nuclear Information System (INIS)

    Zapata, F.; Arrillaga, J.L.

    2002-01-01

    Many soils of the tropics and subtropics under continuous cultivation are very infertile, thus poor yields are obtained and little crop residues remain to protect the soils from degrading erosion. External nutrient inputs in the form of chemical fertilizers, organic materials and other nutrients sources are essential for developing sustainable agricultural production systems. As chemical fertilizers are costly for developing countries with insufficient foreign currency for their purchase and their supplies are limited and irregular for small landholders, alternative nutrient sources must be sought and evaluated for use in dominant agricultural production systems. Locally available organic materials of different origin are potential sources of nutrients. One such source with high agronomic potential is guano. The present study was carried out to evaluate the agronomic effectiveness of two guano materials of different origin (Zaire and Peru) as sources of nitrogen and phosphorus as compared to chemical fertilizers (ammonium sulfate and triple superphosphate) using isotopic ( 15 N and 32 P) techniques. Using the classical method of comparing dry matter weight and P uptake, no significant differences among the tested guano sources were found. The use of the isotopic techniques allowed a quantitative assessment of the N and P supply to crops. Both guano materials were found to be good sources of N but in contrast were poor sources of phosphorus. In addition, from the agronomic evaluation, it was found that the guano of Zaire and the ammonium sulfate were N sources of equivalent efficiency and the guano of Peru even slightly better than the ammonium sulfate. As expected, P in the single superphosphate was as available to the P in the triple superphosphate. However, the substitution ratios for the guano sources were relatively high. Thus, 1 kg P as single superphosphate was equivalent to 9.5 kg P as guano from Zaire or 12.5 kg P as guano from Peru. Further field trials in

  4. MEANS OF ESTABLISHING CHURCH PROPERTY AND FUNDING SOURCES

    Directory of Open Access Journals (Sweden)

    2013-07-01

    Regarding the administration of goods, the Church finds guidance in the laws of the State to which it belongs (Stan, 1952 but taking into consideration the fact that the Church cannot “have its special principles and rules contradicted”(Floca, 1990: 448. However, the church, in fulfilling its purpose - the salvation of believers, needs wealth or heritage. This is not to understand that the Church can “lose its essential character, supernatural character, because, for the Church the earthly possessions and temporal happiness are not an immediate end” (Floca, 1990: 451-452. To understand the Church’s sources of financing it is necessary to take account of its properties. Along the time the church was holder of ownership rights. Its property had to be maintained, at least, so it needed funding. The Church’s canonical and statutory provisions are those governing the Church’s source of funding. They cannot conclusively be understood without observing the principles and rules specific for the ecclesiastical wealth management. Noted should be that previously there were no generally accepted rules on the management of financial resources of the church. The canonical, legal and statutory establishments have become customary in time, making it possible this way, by the dioceses supervisors, that sources of funding should be directed towards the maintenance of the Church, of the worship and of social activities.

    Betz, Marian E; Miller, Matthew; Barber, Catherine; Miller, Ivan; Sullivan, Ashley F; Camargo, Carlos A; Boudreaux, Edwin D

    2013-10-01

    We sought to examine the beliefs and behaviors of emergency department (ED) providers related to preventing suicide by reducing suicidal patients' access to lethal methods (means restriction) and identify characteristics associated with asking patients about firearm access. Physicians and nurses at eight EDs completed a confidential, voluntary survey. The response rate was 79% (n = 631); 57% of respondents were females and 49% were nurses. Less than half believed, "most" or "all" suicides are preventable. More nurses (67%) than physicians (44%) thought "most" or "all" firearm suicide decedents would have died by another method had a firearm been unavailable (P suicidal patients about firearm access varied across five patient scenarios: suicidal with firearm suicide plan (64%), suicidal with no suicide plan (22%), suicidal with nonfirearm plan (21%), suicidal in past month but not today (16%), and overdosed but no longer suicidal (9%). In multivariable logistic regression, physicians were more likely than nurses to "almost always" or "often" ask about a firearm across all five scenarios, as were older providers and those who believed their own provider type was responsible for assessing firearm access. Many ED providers are skeptical about the preventability of suicide and the effectiveness of means restriction, and most do not assess suicidal patients' firearm access except when a patient has a firearm suicide plan. These findings suggest the need for targeted staff education concerning means restriction for suicide prevention. © 2013 Wiley Periodicals, Inc.

  10. Meaning

    Science.gov (United States)

    Harteveld, Casper

    The second world to be considered concerns Meaning. In contrast to Reality and Play, this world relates to the people, disciplines, and domains that are focused on creating a certain value. For example, if this value is about providing students knowledge about physics, it involves teachers, the learning sciences, and the domains education and physics. This level goes into the aspects and criteria that designers need to take into account from this perspective. The first aspect seems obvious when we talk of “games with a serious purpose.” They have a purpose and this needs to be elaborated on, for example in terms of what “learning objectives” it attempts to achieve. The subsequent aspect is not about what is being pursued but how. To attain a value, designers have to think about a strategy that they employ. In my case this concerned looking at the learning paradigms that have come into existence in the past century and see what they have to tell us about learning. This way, their principles can be translated into a game environment. This translation involves making the strategy concrete. Or, in other words, operationalizing the plan. This is the third aspect. In this level, I will further specifically explain how I derived requirements from each of the learning paradigms, like reflection and exploration, and how they can possibly be related to games. The fourth and final aspect is the context in which the game is going to be used. It matters who uses the game and when, where, and how the game is going to be used. When designers have looked at these aspects, they have developed a “value proposal” and the worth of it may be judged by criteria, like motivation, relevance, and transfer. But before I get to this, I first go into how we human beings are meaning creators and what role assumptions, knowledge, and ambiguity have in this. I will illustrate this with some silly jokes about doctors and Mickey Mouse, and with an illusion.

    The “Family Smoking Prevention and Tobacco Control Act” was signed into law on June 22, 2009. The bill grants the Federal Food and Drug Administration (FDA) an authority to regulate the manufacturing and marketing of tobacco products. Tobacco leaf is not subject to the regulation. As a result, it is not apparent what it does mean to tobacco growers. However, since the demand for tobacco is in large part determined by the demand for cigarettes, a change in demand for cigarettes due to the FDA ...

    2005-12-15

    The main objective of the PhD project has been to develop concepts and methods that can be used to define, illustrate, analyse, and improve safety barriers in the operational phase of offshore oil and gas production platforms. The main contributions of this thesis are; Clarification of the term safety barrier with respect to definitions, classification, and relevant attributes for analysis of barrier performance Development and discussion of a representative set of hydrocarbon release scenarios Development and testing of a new method, BORA-Release, for qualitative and quantitative risk analysis of hydrocarbon releases Safety barriers are defined as physical and/or non-physical means planned to prevent, control, or mitigate undesired events or accidents. The means may range from a single technical unit or human actions, to a complex socio-technical system. It is useful to distinguish between barrier functions and barrier systems. Barrier functions describe the purpose of safety barriers or what the safety barriers shall do in order to prevent, control, or mitigate undesired events or accidents. Barrier systems describe how a barrier function is realized or executed. If the barrier system is functioning, the barrier function is performed. If a barrier function is performed successfully, it should have a direct and significant effect on the occurrence and/or consequences of an undesired event or accident. It is recommended to address the following attributes to characterize the performance of safety barriers; a) functionality/effectiveness, b) reliability/ availability, c) response time, d) robustness, and e) triggering event or condition. For some types of barriers, not all the attributes are relevant or necessary in order to describe the barrier performance. The presented hydrocarbon release scenarios include initiating events, barrier functions introduced to prevent hydrocarbon releases, and barrier systems realizing the barrier functions. Both technical and human

    This work is concerned with the localization of gas source in dynamic indoor environment using a single mobile robot system. Algorithms such as Braitenberg, Zig-Zag and the combination of the two were implemented on the mobile robot as gas plume searching and tracing behaviours. To calculate the gas source location, a weighted arithmetic mean strategy was used. All experiments were done on an experimental testbed consisting of a large gas sensor array (LGSA) to monitor real-time gas concentration within the testbed. Ethanol gas was released within the testbed and the source location was marked using a pattern that can be tracked by a pattern tracking system. A pattern template was also mounted on the mobile robot to track the trajectory of the mobile robot. Measurements taken by the mobile robot and the LGSA were then compared to verify the experiments. A combined total of 36.5 hours of real time experimental runs were done and the typical results from such experiments were presented in this paper. From the results, we obtained gas source localization errors between 0.4m to 1.2m from the real source location.

    The aim of this article is to present the findings concerning scientific fraud that have appeared in case reports. Deliberate scientific fraud does exist. The fact that most of the documented cases have occurred in Anglo-Saxon countries seems to indicate, not that Anglo-Saxons are more prone to scientific fraud, but rather that they have been more successful in bringing it to light. Since 1974, 72 cases have been reported in which there was either conclusive evidence or else a strong presumption of fraud: one case in Switzerland, one in Canada, four in Australia, 14 in Great Britain and 52 in the United States. Fraud is estimated to affect 2-5% of clinical research trials. Referees and readers do not set out to track fraud. The American Commission has proposed the terms "misappropriation, interference, misrepresentation" to define fraud. Voluntary fraud is hidden and its detection delayed. In well-known cases, more than 5 years elapsed before the information reached the scientific community. Whistle blowers must sustain a determined effort to denounce fraud over a period of 1-3 years if they are to trigger an investigation. Some whistle blowers have themselves been accused of fraud because their claims proved so embarrassing. Fraud can lead to severe accidents and generate expenditure that those responsible, or the institutions they work for, will never pay back. Frauders are usually motivated by the desire for material gain or the desire to become well-known. The motivating factor may be personal enrichment, or a need for funds for a not-for-profit association. People found guilt of fraud always have good excuses. Some simply do not realize what they have done. A knowledge of research methodology and critical appraisal methods can help to prevent fraud. Good clinical, laboratory and manufacturing practice can help to prevent misconduct and trickery. Audits and inspections are another essential means of combatting fraud.

    Spontaneous mean arterial pressure (MAP) variability may be mainly due to fluctuations in cardiac output (CO) and total peripheral resistance (TPR). While high frequency (HF ∼ 0.25 Hz) oscillations in MAP are ultimately driven by respiration, the source of low frequency (LF ∼ 0.1 Hz) fluctuations has not been fully elucidated. It is known that CO buffers these oscillations, but there is no evidence on its potential role in also generating them. The main goal was to determine whether CO is a source of LF variability in MAP. Six dogs were chronically instrumented to obtain beat-to-beat measurements of CO and MAP while the dogs were fully awake and at rest. A causal dynamic model was identified to relate the fluctuations in CO to MAP. The model was then used to predict the MAP fluctuations from the CO fluctuations. The CO fluctuations were able to predict about 70% of the MAP oscillations in the HF band but showed no predictive value in the LF band. Hence, respiration induces CO fluctuations in the HF band that, in turn, cause MAP oscillations, while TPR fluctuations appear to be the dominant mediator of LF fluctuations of MAP. CO is not a significant source of these oscillations, and it may only be responsible for dampening them, likely through the baroreflex. (paper)

  1. A statistical approach for evaluating the effectiveness of heartworm preventive drugs: what does 100% efficacy really mean?

    2017-11-01

    Full Text Available Abstract Background Initial studies of heartworm preventive drugs all yielded an observed efficacy of 100% with a single dose, and based on these data the US Food and Drug Administration (FDA required all products to meet this standard for approval. Those initial studies, however, were based on just a few strains of parasites, and therefore were not representative of the full assortment of circulating biotypes. This issue has come to light in recent years, where it has become common for studies to yield less than 100% efficacy. This has changed the landscape for the testing of new products because heartworm efficacy studies lack the statistical power to conclude that finding zero worms is different from finding a few worms. Methods To address this issue, we developed a novel statistical model, based on a hierarchical modeling and parametric bootstrap approach that provides new insights to assess multiple sources of variability encountered in heartworm drug efficacy studies. Using the newly established metrics we performed both data simulations and analyzed actual experimental data. Results Our results suggest that an important source of modeling variability arises from variability in the parasite establishment rate between dogs; not accounting for this can overestimate the efficacy in more than 40% of cases. We provide strong evidence that ZoeMo-2012 and JYD-34, which both were established from the same source dog, have differing levels of susceptibility to moxidectin. In addition, we provide strong evidence that the differences in efficacy seen in two published studies using the MP3 strain were not due to randomness, and thus must be biological in nature. Conclusion Our results demonstrate how statistical modeling can improve the interpretation of data from heartworm efficacy studies by providing a means to identify the true efficacy range based on the observed data. Importantly, these new insights should help to inform regulators on how to

  2. Prevention of illicit trafficking of nuclear material and radioactive sources

    Full text: Countries like Russia, which have a large nuclear industry, export a significant number of radioactive sources and substances. Some of them are nuclear material. In general, it is the task of the customs inspectors to verify that the content of the shipment is in agreement with the declaration (as safeguards inspectors verify operators declarations). In case of other goods, this is easy. The consignment can be opened and the content can be seen and compared with the declaration. In the case of radioactive shipments this cannot be done. The radioactive substance is in a shielded container and opening is often only possible in a hot cell. Opening of the package and measurement of the removed source in presence of the customs inspector is impossible because the customs inspector is impossible because the customs control begins only after the declaration has been registered. Therefore, the Russian customs authorities have contracted a company to develop a gamma spectrometer, which can be used to verify the source, even if inside the shielded shipping container. Throughout the country - near the where many shipments or receivables take place - there are 18 customs offices, equipped with gamma spectrometers and special software. If a container arrives for customs inspection, its design is called from a database. Then the gamma spectrum outside the container is measured and the measured gamma peak energy and intensity is compared with the expected, which is calculated by software based on the design information of the container. This approach works well. Several cases were already discovered in Russia, where there were attempts to use legal shipments for smuggling radioactive sources. I would like to mention some technical problems concerning control of legal export and import of radioactive sources: a) There are not enough commercial suppliers, which offer the needed equipment; because of lack of competition prices for the equipment are too high b) Presently

  3. The Mean Curvature of the Influence Surface of Wave Equation With Sources on a Moving Surface

    The mean curvature of the influence surface of the space-time point (x, t) appears in linear supersonic propeller noise theory and in the Kirchhoff formula for a supersonic surface. Both these problems are governed by the linear wave equation with sources on a moving surface. The influence surface is also called the Sigma - surface in the aeroacoustic literature. This surface is the locus, in a frame fixed to the quiescent medium, of all the points of a radiating surface f(x, t) = 0 whose acoustic signals arrive simultaneously to an observer at position x and at the time t. Mathematically, the Sigma- surface is produced by the intersection of the characteristic conoid of the space-time point (x, t) and the moving surface. In this paper, we derive the expression for the local mean curvature of the Sigma - space of the space-time point for a moving rigid or deformable surface f(x, t) = 0. This expression is a complicated function of the geometric and kinematic parameters of the surface f(x, t) = 0. Using the results of this paper, the solution of the governing wave equation of high speed propeller noise radiation as well as the Kirchhoff formula for a supersonic surface can be written as very compact analytic expression.

  5. Chemicals and excess materials disposition during deactivation as a means of pollution prevention

    Godfrey, S.D.

    1998-01-01

    This paper presents several innovative and common sense approaches to pollution prevention that have been employed during facility deactivation at the Hanford Site in South Central Washington. It also presents several pollution prevention principles applicable to other projects. Innovative pollution prevention ideas employed at the Hanford site during facility deactivation included: (1) Recycling more than 185,000 gallons of radioactively contaminated nitric acid by sending it to an operating nuclear fuels reprocessing facility in England; (2) Recycling millions of pounds of chemicals and excess materials to other industries for reuse; (3) Evaporating flush water at a low rate and discharging it into the facility exhaust air stream to avoid discharging thousands of gallons of liquid to the soil column; and (4) Decontaminating and disposing of thousands of gallons of radioactively contaminated organic solvent waste to a RCRA licensed, power-producing, commercial incinerator. Common sense pollution prevention ideas that were employed include recycling office furniture, recycling paper from office files, and redeploying tools and miscellaneous process equipment. Additional pollution prevention occurred as the facility liquid and gaseous discharge streams were deactivated. From the facilities deactivation experiences at Hanford and the ensuing efforts to disposition excess chemicals and materials, several key pollution prevention principles should be considered at other projects and facilities, especially during the operational periods of the facility's mission. These principles include: Institute pollution prevention as a fundamental requirement early in the planning stage of a project or during the operational phase of a facility's mission; Promote recognition and implementation of pollution prevention initiatives; Instill pollution prevention as a value in all participants in the project or facility work scope; Minimize the amount of chemical products and materials

  7. Two sources of meaning in infant communication: preceding action contexts and act-accompanying characteristics.

    How do infants communicate before they have acquired a language? This paper supports the hypothesis that infants possess social-cognitive skills that run deeper than language alone, enabling them to understand others and make themselves understood. I suggested that infants, like adults, use two sources of extralinguistic information to communicate meaningfully and react to and express communicative intentions appropriately. In support, a review of relevant experiments demonstrates, first, that infants use information from preceding shared activities to tailor their comprehension and production of communication. Second, a series of novel findings from our laboratory shows that in the absence of distinguishing information from preceding routines or activities, infants use accompanying characteristics (such as prosody and posture) that mark communicative intentions to extract and transmit meaning. Findings reveal that before infants begin to speak they communicate in meaningful ways by binding preceding and simultaneous multisensory information to a communicative act. These skills are not only a precursor to language, but also an outcome of social-cognitive development and social experience in the first year of life. © 2014 The Author(s) Published by the Royal Society.

  13. Sealed Radioactive Sources. Information, Resources, and Advice for Key Groups about Preventing the Loss of Control over Sealed Radioactive Sources

    International Nuclear Information System (INIS)

    2013-10-01

    Among its many activities to improve the safety and security of sealed sources, the IAEA has been investigating the root causes of major accidents and incidents since the 1980's and publishes findings so that others can learn from them. There are growing concerns today about the possibility that an improperly stored source could be stolen and used for malicious purposes. To improve both safety and security, information needs to be in the hands of those whose actions and decisions can prevent a source from being lost or stolen in the first place. The IAEA developed this booklet to help improve communication with key groups about hazards that may result from the loss of control over sealed radioactive sources and measures that should be implemented to prevent such loss of control. Many people may benefit from the information contained in this booklet, particularly those working with sources and those likely to be involved if control over a source is lost; especially: officials in government agencies, first responders, medical users, industrial users and the metal recycling industry. The general public may also benefit from an understanding of the fundamentals of radiation safety. This booklet is comprised of several stand-alone chapters intended to communicate with these key groups. Various accidents that are described and information that is provided are relevant to more than one key group and therefore, some information is repeated throughout the booklet. This booklet seeks to raise awareness of the importance of the safety and security of sealed radioactive sources. However, it is not intended to be a comprehensive 'how to' guide for implementing safety and security measures for sealed radioactive sources. For more information on these measures, readers are encouraged to consult the key IAEA safety and security-related publications identified in this booklet

    The present communication concerns factors, the application of which may contribute to reduce the transfer rate of sexually transmitted infections (STIs), including geomedical aspects. The factors elaborated on are, e.g. maternal health care, sexual education early in life, health prevention programmes and sexual risk reduction counselling of commercial sex workers, screening activities as well as recommendation of preventive strategies based on analyses of monitored data from screening studies. Case- and carrier detection stimulated by society-, company- and client-initiatives, syndrome-based therapy of STIs, barrier- (condom) and hormonal anticonception counselling and the special features of HIV/AIDS prevention are also elaborated on. The spread of sexually transmitted infections (STIs) in a society and between various geographic areas within and between countries is dependent of a large number of factors. The relative importance of all such factors have been rather poorly analysed simultaneously in one area, particularly with regard to their interactive impact on the epidemiology of these infections. Such analyses must, however, be a prerequisite for any successful intervention programme attempting to reduce the spread of STIs in a society. The present communication will elaborate on a number of factors (tab. I), the application of which is believed to be important for reducing the transfer rate of STIs, not only between individuals living in one and the same community but also between geographically separated community.

    2001-04-01

    This article describes a new method for 3D QEEG tomography in the frequency domain. A variant of Statistical Parametric Mapping is presented for source log spectra. Sources are estimated by means of a Discrete Spline EEG inverse solution known as Variable Resolution Electromagnetic Tomography (VARETA). Anatomical constraints are incorporated by the use of the Montreal Neurological Institute (MNI) probabilistic brain atlas. Efficient methods are developed for frequency domain VARETA in order to estimate the source spectra for the set of 10(3)-10(5) voxels that comprise an EEG/MEG inverse solution. High resolution source Z spectra are then defined with respect to the age dependent mean and standard deviations of each voxel, which are summarized as regression equations calculated from the Cuban EEG normative database. The statistical issues involved are addressed by the use of extreme value statistics. Examples are shown that illustrate the potential clinical utility of the methods herein developed.

    Biofouling is a major problem faced by marine industries. Physical and chemical treatments are available to control fouling, but most are costly, time consuming or negatively affect the environment. The use of aeration (ie continuous streams of air bubbles) to prevent fouling was examined. Experiments were conducted at three sites with different benthic communities. Experimental panels (10 cm x 10 cm; PVC and concrete) were deployed with or without aeration. Aeration flowed continuously from spigots 0.5 m below the panels at a rate of approximately 3.3 to 5.0 l min(-1). After 1 and 4 weeks, aerated PVC panels from all sites had significantly less fouling than non-aerated controls. Aeration reduced fouling on both the PVC and concrete surfaces. Fouling was reduced on panels directly in bubble streams while panels 30 cm and 5 m away had significantly more fouling. Thus, under the conditions used in this study, aeration appears to be an effective and simple way to prevent fouling.

    French law as regards renunciation to mining concessions calls for the mining operator to first undertake analyses of the risks represented by their underground mining works. The problem of gas migration to the surface is especially significant in the context of coal mines. This is because mine gas can migrate to the earth's surface, then present significant risks: explosion, suffocation or gas poisoning risks. As part of the scheduled closure of all coal mining operations in France, INERIS has drawn up, at the request of national mining operator Charbonnages de France, a general methodology for assessing the risk linked to gas in the context of closed coal mines. This article presents the principles of this methodology. An application example based on a true case study is then described. This is completed by a presentation of the preventive and monitoring resources recommended and usually applied in order to manage the risk linked to gaseous emissions. (authors)

    In alternating type activated sludge nutrient removal processes, the denitrification rate can be limited by the availability of readily-degradable carbon substrate. A control strategy is proposed by which an easily metabolizable COD source is added directly to that point in the process at which...... denitrification momentarily occurs. This approach serves to increase the denitrification rate on demand, thereby allowing the accumulation of nitrate and nitrite during periods of peak nitrogen loading to be reduced or avoided.

    2008-01-01

    General practitioners (GPs) occupy a central position in health care and often have demanding working situations. This corps shows signs of exhaustion, and many consider quitting their job or plan to retire early. It is therefore urgent to find ways of improving GP's satisfaction with their work. One approach might be Balint group participation. The aim of this study was to explore GPs' experience of participating in Balint groups and its influence on their work life. We conducted a descriptive, qualitative study. Nine GPs who had participated in Balint groups for 3 to 15 years were interviewed. A phenomenologic analysis was carried out to describe the phenomenon of Balint group participation. The GPs perceived that their Balint group participation influenced their work life. Analyses revealed several interrelating themes: competence, professional identity, and a sense of security, which increased through parallel processes, creating a base of endurance and satisfaction, thus enabling the GPs to rediscover the joy of being a physician. The GPs in this study described their Balint group participation as beneficial and essential to their work life as physicians in several ways. It seemed to increase their competence in patient encounters and enabled them to endure in their job and find joy and challenge in their relationships with patients. Balint groups might thus help GPs handle a demanding work life and prevent burnout. These groups might not suit all GPs, however, and additional ways to reduce stress and increase job satisfaction should be offered.

    Fink-Bennett, D.; Pattekar, A.M.

    2002-01-01

    Aim: The sensitivity and specificity of rest/stress (R/S) myocardial perfusion imaging (MPI) in detecting an acute ischemic coronary syndrome (AICS) was determined in 100 consecutive patients (pts) admitted to the Chest Pain Clinic-Observation Unit (CPC-OU) with chest pain (CP) of suspected cardiac etiology and a negative (neg) or non diagnostic (dx) EKG. There were 57 females and 43 males, 30-83 years of age. 50 studies were performed from 1/15/98 to 4/2/98; 50 from 11/19/99 to 1/10/00. Material and Methods: An AICS was deemed present if a reversible perfusion defect was demonstrated scintigraphically; a ?50% luminal narrow angiographically. No AICS if the pt had a normal R/S MPI, a fixed defect with normal wall motion and thickening, a neg cardiac catheterization, or was free of cardiac symptoms and had no history of a vascular event for 2-3 years post CPC-OU admission. 13 pts with a positive MPI had a cardiac catheterization, none with a neg MPI. SPECT rest MPI's were performed 30-90 minutes (mins) post 10.0 mCi of technetium 99m Sestamibi. SPECT stress MPI's were performed following a 6-8 hour acute myocardial infarction enzyme (CP-MB/Troponin 1) rule out and 30-90 mins post 30.0 mCi of technetium 99m Sestamibi. Results: 29 pts were lost to follow-up. There were 12 true positive, 5 false positive, 54 true negative and 0 false negative studies. The sensitivity, specificity, positive and negative predictive value of a R/S MPI in detecting an AICS is 100%, 91%, 70% and 100%, respectively. An AICS was detected in 12% of pts admitted to the CPC-OU; a finding that correlates with its reported incidence of 2-12%. 6 were managed medically, 3 required emergent bypass surgery, 3 were stented. Conclusion: R/S MPI should be included in the CPC-OU dx work-up of pts with CP of suspected cardiac etiology to prevent missed AICS diagnoses. Patient care will be optimized and health care and medical malpractice awards for failure to diagnosis an acute myocardial infarction

    A Be O moderated reactor using slightly enriched uranium oxide as fuel was studied by the pulsed neutron source technique. The neutron lifetime was measured in two different cores without reflector, then attempts were made at the measurement of great negative reactivities introduced into the reactor under the following forms: decrease of the volume of the un reflected core, introduction of absorbing cadmium rods, removal of fuel at the periphery of the critical core while maintaining a constant height, and substitution of fuel elements by less reactive elements. In all cases, the results are compared with the data obtained by another type of experiment or by computation. (author) [fr

    As part of the Soviet-Norwegian programme in geology and geophysics, an investigation of electroconductivity in the upper part of the Earth's crust was carried out in 1989-1991. The measurements were performed using an electrical dipole source, 'Khibiny', which is situated on the Kola Peninsula, close to the Norwegian border. A 26 kW car generator supplied square pulses with a peak to peak current of 100 A in the 'Khibiny' cable; at a frequency of 0.125 Hz. The distance between the source and the measuring points varied from 60 to 130 km. A stacking technique was applied to identify the weak electromagnetic signals. All the measurements were conducted using a six-component digital automatic station, ZAIS, produced at the Institute of Fundamental Physics of the USSR Academy of Science. As a result of the studies, several conductive current channels in the Pechenga structure on the Russian side of the border were traced into the Pasvik area in Norway. Detailed information on the deeper parts of the electroconductive structures in this area was obtained.

    Light source technological performance is key to enabling chipmaker yield and production success. Just as important is ensuring that performance is consistent over time to help maintain as high an uptime as possible on litho-cells (scanner and track combination). While it is common to see average tool uptime of over 99% based on service intervention time, we will show that there are opportunities to improve equipment availability through a multifaceted approach that can deliver favorable results and significantly improve on the actual production efficiency of equipment. The majority of chipmakers are putting light source data generated by tools such as Cymer OnLine (COL), OnPulse Plus, and SmartPulse to good use. These data sets, combined with in-depth knowledge of the equipment, makes it possible to draw powerful conclusions that help increase both chip manufacturing consistency as well as equipment productivity. This discussion will focus on the latter, equipment availability, and how data analysis can help increase equipment availability for Cymer customers. There are several types of opportunities for increasing equipment availability, but in general we can focus on two primary categories: 1) scheduled downtime and 2) unscheduled downtime. For equipment that is under control of a larger entity, as the laser is to the scanner, there are additional categories related to either communication errors or better synchronization of events that can maximize overall litho-cell efficiency. In this article we will focus on general availability without highlighting the specific cause of litho-cell (laser, scanner and track). The goal is to increase equipment available time with a primary focus is on opportunities to minimize errors and variabilities.

    2012-01-01

    Given the finite resources allocated to suicide prevention, it is necessary to direct resources into interventions that are most likely to have an impact. This article tests for possible impacts on youth suicides of a cost-intensive Australian policy change (increased firearms restriction) that limited access to a means of suicide. Suicide rates by different age groups and methods were examined for structural breaks, using Zivot-Andrews and Quandt tests. No breakpoint was found in firearm suicide among Australian youth around the time of the 1996 legislative changes. Method restriction in the form of firearms legislation could not be tied to a corresponding impact on youth suicide.

    2014-05-01

    Quantification of carbon emissions in urbanized areas constitutes an important part of the current research on the global carbon cycle. As the carbon isotopic composition of atmospheric carbon dioxide can serve as a fingerprint of its origin, systematic observations of δ13CO2 and/or Δ14CO2, combined with atmospheric CO2mixing ratio measurements can be used to better constrain the urban sources of this gas. Nowadays, high precision optical analysers based on absorption of laser radiation in the cavity allow a real-time monitoring of atmospheric CO2 concentration and its 13CO2/12CO2 ratio, thus enabling better quantification of the contribution of different anthropogenic and natural sources of this gas to the local atmospheric CO2load. Here we present results of a 2-year study aimed at quantifying carbon isotopic signature of the mean CO2 source and its seasonal variability in the urban atmosphere of Krakow, southern Poland. The Picarro G2101-i CRDS isotopic analyser system for CO2and 13CO2/12CO2 mixing ratio measurements has been installed at the AGH University of Science and Technology campus in July 2011. Air inlet was located at the top of a 20m tower mounted on the roof of the faculty building (ca. 42m a.g.l.), close to the city centre. While temporal resolution of the analyser is equal 1s, a 2-minute moving average was used for calculations of δ13CO2 and CO2 mixing ratio to reduce measurement uncertainty. The measurements were calibrated against 2 NOAA (National Oceanic and Atmospheric Administration) primary standard tanks for CO2 mixing ratio and 1 JRAC (Jena Reference Air Cylinder) isotope primary standard for δ13C. A Keeling approach based on two-component mass and isotope balance was used to derive daily mean isotopic signatures of local CO2 from individual measurements of δ13CO2 and CO2 mixing ratios. The record covers a 2-year period, from July 2011 to July 2013. It shows a clear seasonal pattern, with less negative and less variable δ13CO2 values

  2. Numerical simulation of the throwing power of cathodic prevention applied to marine reinforced concrete piles by means of sacrificial anodes

    The paper deals with the determination of current and potential distribution in reinforced concrete elements partially submerged in seawater aimed at predicting the throwing power of cathodic prevention applied by means of sacrificial anodes. Previous laboratory studies carried out on reinforced concrete columns 15 cm x 15 cm x 120 cm showed that the use of sacrificial anodes placed in the solution at the bottom of the column could provide protection of corroding steel bars in the emerged part of the pile up to about 60 cm from the water level. However, if sacrificial anodes were applied when the concrete was chloride free and steel bars were still passive, even the highest bar, placed at 1 m from the level of water, was protected. This is due to the higher polarizability of passive steel, that makes the throwing power of cathodic prevention higher compared to that of cathodic protection. In order to extend the results obtained on small-scale specimens to elements of higher dimensions, numerical simulations of current and potential distribution were carried out. Two-dimensional models were set up of reinforced concrete piles containing steel bars at different heights protected with sacrificial anodes placed in the water in which they were partially submerged. Boundary conditions describing the electrochemical behaviour of bars were obtained from polarisation curves measured on the previously mentioned columns. Values of concrete conductivity at different heights from the water level were also obtained from those tests. Several cases were considered, representative of conditions differing in electrochemical behaviour of steel bars, dimensions of element, position of sacrificial anodes. The paper discusses the results obtained from the models and compares them in terms of the throwing power that can be reached by using sacrificial anodes immersed in the seawater to protect reinforcing steel bars in the emerged part of a pile.

    2016-12-01

    The evidence that many of the findings in the published literature may be unreliable is compelling. There is an excess of positive results, often from studies with small sample sizes, or other methodological limitations, and the conspicuous absence of null findings from studies of a similar quality. This distorts the evidence base, leading to false conclusions and undermining scientific progress. Central to this problem is a peer-review system where the decisions of authors, reviewers, and editors are more influenced by impressive results than they are by the validity of the study design. To address this, BMC Psychology is launching a pilot to trial a new 'results-free' peer-review process, whereby editors and reviewers are blinded to the study's results, initially assessing manuscripts on the scientific merits of the rationale and methods alone. The aim is to improve the reliability and quality of published research, by focusing editorial decisions on the rigour of the methods, and preventing impressive ends justifying poor means.

    The purpose of this literature review is to gather available information of the methods to prevent a source term of methyl iodide during a core melt accident. The most widely studied methods for nuclear power plants include the impregnated carbon filters and alkaline additives and sprays. It is indicated that some deficiencies of these methods may emerge. More reactive impregnants and additives could make a great improvement. As a new method in the field of nuclear applications, the potential of transition metals to decompose methyl iodide, is introduced in this review. This area would require an additional research, which could elucidate the remaining questions of the reactions. The ionization of the gaseous methyl iodide by corona-discharge reactors is also shortly described. (au)

    Full Text Available For long time vegetables were thought only as sources of several vitamins; however, it has been shown that vegetables contain other component, which is also important for maintaining body's health, i.e., dietary fiber. Dietary fiber is a group of polysaccharides oan other polymers, which cannot be digested by upper gastro-intestinal system of human. Dietary fiber can be grouped as soluble and insoluble dietary fiber, showing in different physiological effect. Soluble dietary fiber (SDF is effective in preventing cardiovascular disease, while insoluble dietary fiber (IDF can prevent the development of colon cancer, diverticulosis as well as obesity.Local vegetables found to contain high SDF (higher than 3,06% db are: watercress, green bean, carrot, eggplant, lettuce, broccoli, spinach, string bean, and aubergine; while which contain high IDF (higher than 40,60% db are: winged bean, watercress, chinese leaves, katuk leaves, lettuce, green bean, broccoli, carrot and spinach. Cooking (i.e. boiling, steaming and pan frying decrease the IDF content of vegetables, while their SDF content is not affected by cooking treatments.

    2016-06-01

    Full Text Available A diet rich in vegetables has been associated with a reduced risk of many diseases related to aging and modern lifestyle. Over the past several decades, many researches have pointed out the direct relation between the intake of bioactive compounds present in tomato and a reduced risk of suffering different types of cancer. These bioactive constituents comprise phytochemicals such as carotenoids and polyphenols. The direct intake of these chemoprotective molecules seems to show higher efficiencies when they are ingested in its natural biological matrix than when they are ingested isolated or in dietary supplements. Consequently, there is a growing trend for improvement of the contents of these bioactive compounds in foods. The control of growing environment and processing conditions can ensure the maximum potential accumulation or moderate the loss of bioactive compounds, but the best results are obtained developing new varieties via plant breeding. The modification of single steps of metabolic pathways or their regulation via conventional breeding or genetic engineering has offered excellent results in crops such as tomato. In this review, we analyse the potential of tomato as source of the bioactive constituents with cancer-preventive properties and the result of modern breeding programs as a strategy to increase the levels of these compounds in the diet.

  9. Plant Ferritin—A Source of Iron to Prevent Its Deficiency

    Zielińska-Dawidziak, Magdalena

    2015-01-01

    Iron deficiency anemia affects a significant part of the human population. Due to the unique properties of plant ferritin, food enrichment with ferritin iron seems to be a promising strategy to prevent this malnutrition problem. This protein captures huge amounts of iron ions inside the apoferritin shell and isolates them from the environment. Thus, this iron form does not induce oxidative change in food and reduces the risk of gastric problems in consumers. Bioavailability of ferritin in human and animal studies is high and the mechanism of absorption via endocytosis has been confirmed in cultured cells. Legume seeds are a traditional source of plant ferritin. However, even if the percentage of ferritin iron in these seeds is high, its concentration is not sufficient for food fortification. Thus, edible plants have been biofortified in iron for many years. Plants overexpressing ferritin may find applications in the development of bioactive food. A crucial achievement would be to develop technologies warranting stability of ferritin in food and the digestive tract. PMID:25685985

    Folic acid supplementation and folate-rich diets are recommended for women of childbearing age worldwide to prevent congenital anomalies. We aimed to determine the current status of folic acid supplementation among pregnant Japanese women and identify means to increase the intake of these supplements. Cross-sectional study. A total of 1862 pregnant women who consulted the perinatal centre from September 2014 to December 2015 completed a questionnaire concerning knowledge about folic acid, sources of information and the use of folic acid supplements. Osaka Medical Center and Research Institute for Maternal and Child Health (Japan). In our study population, only 20·5 % of pregnant women took folic acid supplements periconceptionally even though 70·4 % knew about the protective effect of folic acid. A multivariate analysis demonstrated that age ≥35 years (OR=2·80; 95 % CI 1·24, 6·29) and knowledge of the benefits of folic acid (OR=2·64; 95 % CI 1·92, 3·62) were associated with periconceptional folic acid use, and multiparity was negatively associated with such use. Compared with those who took folic acid supplements periconceptionally, women who did not take supplements received information through passive and less interactive media. Although folic acid awareness was relatively high among pregnant Japanese women, folic acid supplementation before conception was insufficient. To increase the intake of folic acid supplements in countries in which foods are not fortified with folic acid, an effective public health approach promoting behavioural change is necessary for women of reproductive age.

    This study focuses on the meanings assigned to practices for cervical cancer prevention among women from low-income neighborhoods in Salvador, Bahia State, Brazil. This was a qualitative study based on content analysis of semi-structured interviews with 15 women 24 to 68 years of age. The results showed high appreciation of the Pap smear test, performed as part of routine gynecological examination (but without the patient necessarily having biomedical knowledge of its role). Besides accessibility and quality of health services, other factors influence the way the women assign meaning to cervical cancer prevention. Moral values associated with sexuality and gender influence risk perception, adoption of preventive practices, and interpretation of cervical cytology results. The ongoing practice of the Pap smear test is part of the construction of femininity, which is associated with maturity and personal responsibility for self care in a context of medicalization of the female body.

    Although growing research focuses on breast cancer screenings, little is known about breast cancer prevention with risk reduction awareness for ethnic differences among college-age women. This study examined breast cancer prevention knowledge, beliefs, and information sources between non-Hispanic and Hispanic college women. Using a cross-sectional study, women at a university in the Southwest completed a 51-item survey about breast cancer risk factors, beliefs, and media and interpersonal information sources. The study was guided by McGuire's Input Output Persuasion Model. Of the 546 participants, non-Hispanic college women (n = 277) and Hispanic college women (n = 269) reported similar basic knowledge levels of modifiable breast cancer risk factors for alcohol consumption (52 %), obesity (72 %), childbearing after age 35 (63 %), and menopausal hormone therapy (68 %) using bivariate analyses. Most common information sources were Internet (75 %), magazines (69 %), provider (76 %) and friends (61 %). Least common sources were radio (44 %), newspapers (34 %), and mothers (36 %). Non-Hispanic college women with breast cancer family history were more likely to receive information from providers, friends, and mothers. Hispanic college women with a breast cancer family history were more likely to receive information from their mothers. Breast cancer prevention education for college women is needed to include risk reduction for modifiable health behavior changes as a new focus. Health professionals may target college women with more information sources including the Internet or apps.

    Primak, A N; Ramirez Giraldo, J C; Liu, X; Yu, L; McCollough, C H

    2009-04-01

    The use of additional spectral filtration for dual-energy (DE) imaging using a dual-source CT (DSCT) system was investigated and its effect on the material-specific DE(ratio) was evaluated for several clinically relevant materials. The x-ray spectra, data acquisition, and reconstruction processes for a DSCT system (Siemens Definition) were simulated using information provided by the system manufacturer, resulting in virtual DE images. The factory-installed filtration for the 80 kV spectrum was left unchanged to avoid any further reductions in tube output, and only the filtration for the high-energy spectrum was modified. Only practical single-element filter materials within the atomic number range of 40 simulations were performed for three attenuation scenarios: Head, body, and large body. The large body scenario was evaluated for the DE acquisition mode using the 100 and 140 kV spectra. The DE(ratio) for calcium hydroxyapatite (simulating bone or calcifications), iodine, and iron were determined for CT images simulated using the modified and factory-installed filtration. Several filter materials were found to perform well at proper thicknesses, with tin being a good practical choice. When image noise was matched between the low- and high-energy images, the spectral difference in mean absorbed energy using tin was increased from 25.7 to 42.7 keV (head), from 28.6 to 44.1 keV (body), and from 20.2 to 30.2 keV (large body). The overlap of the signal spectra for energies below 80 keV was reduced from 78% to 31% (head), from 93% to 27% (body), and from 106% to 79% (large body). The DE(ratio) for the body attenuation scenario increased from 1.45 to 1.91 (calcium), from 1.84 to 3.39 (iodine), and from 1.73 to 2.93 (iron) with the additional tin filtration compared to the factory filtration. This use of additional filtration for one of the x-ray tubes used in dual-source DECT dramatically increased the difference between material-specific DE ratios, e.g., from 0.39 to 1

    Preventive health services are important for child development, and parents play a key role in facilitating access to services. This study examined how parents' reasons for not having a usual source of care were associated with their children's receipt of preventive services. We used pooled data from the 2011-2014 National Health Interview Survey (n = 34 843 participants). Parents' reasons for not having a usual source of care were framed within the Penchansky and Thomas model of access and measured through 3 dichotomous indicators: financial barriers (affordability), attitudes and beliefs about health care (acceptability), and all other nonfinancial barriers (accessibility, accommodation, and availability). We used multivariable logistic regression models to test associations between parental barriers and children's receipt of past-year well-child care visits and influenza vaccinations, controlling for other child, family, and contextual factors. In 2014, 14.3% (weighted percentage) of children had at least 1 parent without a usual source of care. Children of parents without a usual source of care because they "don't need a doctor and/or haven't had any problems" or they "don't like, trust, or believe in doctors" had 35% lower odds of receiving well-child care (adjusted odds ratio = 0.65; 95% CI, 0.56-0.74) and 23% lower odds of receiving influenza vaccination (adjusted odds ratio = 0.77; 95% CI, 0.69-0.86) than children of parents without those attitudes and beliefs about health care. Financial and other nonfinancial parental barriers were not associated with children's receipt of preventive services. Results were independent of several factors relevant to children's access to preventive health care, including whether the child had a usual source of care. Parents' attitudes and beliefs about having a usual source of care were strongly associated with their children's receipt of recommended preventive health services. Rates of receipt of child preventive

    The World Health Organization identifies suicide among the top 10 causes of death in many countries with an overall mortality rate of 16 per 100,000 inhabitants. Furthermore suicide attempts present a frequency 4-10 times greater than the suicidal events, representing also one of the main risk factors to lead to recurrent attempts of suicide. In 2008 the Autonomous Province of Trento launched a suicide prevention pogram called "Invitation to Life" which includes various interventions intended to counter the phenomenon of suicide in the region. Actually the epidemiological research upon the phenomenon of suicide in Trentino region is one of the main pillars of the project: it represents a fundamental requirement to identify risk and protective factors in the population in order to adopt more specific and effective preventive strategies. This article aims to present methods and instruments for epidemiological monitoring of suicide and attempted suicide which are applied in Trentino and to describe results after seven years from the beginning of the local prevention program "Invitation to life".

    Full Text Available The objective is to implement a visual impairment prevention program into a vocational school’s academic process for the risk group students and to determine its effectiveness based on the dynamics of comprehensive scoring assessment of the degree of visual pathology risk. Materials and methods. Observed were 91 students (35 boys and 56 girls. For the formative experiment purposes, a study group (SG consisting of 10 persons (4 boys and 6 girls with a visual organ pathology who performed the designed preventive program and a reference group (RG consisting of 10 persons (5 boys and 5 girls with a visual organ pathology who studied under the usual program were selected The program effectiveness was evaluated by changes in the students’ subjective evaluation of their visual comfort. The Relative Risk Index (RR was used to perform a rough evatuation of the cause-effect relations between the acting factor and the effect appearance. The output characteristics were compared between the groups using χ2 tests (binary variables, t-tests (continuous variables, Mann-Whitney test for comparing the distribution of ordinal variables, and Wilcoxon test (related sampling. Results. The dynamics in the RG over the academic year showed an increase in the scoring assessment of the visual fatigue, which constituted 90.6 ± 10.3%. At the same time, the students in the SG demonstrated a reduced intensity and number of complaints about the visual analyzer fatigue. In the SG, the complex scoring assessment reliably decreased from 9.8 ± 0.8 to 7.2 ± 0.9 c.u. The implemented preventive program had a positive effect on the complaints: “the desire to bring the text closer to the eyes” (relative risk (RR = 6.0, χ2 = 5.6, p <0.05, “the feeling of existence of certain periods of change in the visual acuity” (relative risk (RR = 3.5; χ2 = 5.1; p <0.05, and the overall assessment of the questionnaire (relative risk (RR = 7.0; χ2 = 7.5; p <0.01.

    A multivariate statistical method has been applied to apportion the atmospheric pollutant concentrations measured by automatic gas analyzers placed on a mobile laboratory for air quality monitoring in Taranto (Italy). In particular, Principal Component Analysis (PCA) followed by Absolute Principal Component Scores (APCS) technique was performed to identify the number of emission sources and their contribution to measured concentrations of CO, NO{sub x}, benzene toluene m+p-Xylene (BTX). This procedure singled out two different sources that explain about 85% of collected data variance. (orig.)

    The atmospheric aerosols sources have been identified in Sao Paulo since the 80´s with the use of receptor models. The Metropolitan Area of São Paulo (MASP) is a megacity with a population of 21 million, corresponding to more than 11% of the total population of Brazil. The first results for the identification of sources of particles were obtained with the application of Absolute Principal Component Analysis, Factor Analysis and Chemical Mass Balance. More recently the Positive Matrix Factorization has been used in combination with the other receptor models. With the improvement of the aerosol composition analytical determination (more elements and better resolution) the source identification has became more accurate. But, in spite of that, the main sources are the same for fine particles: vehicular emission, secondary formation and biomass burning. The large amount of biofuels used in the MASP makes this region an important example of the atmospheric chemistry of fossil fuel and biofuel emissions. The 7 million vehicles can run on gasohol, ethanol (95% ethanol + 5% gasoline) and biodiesel (mostly for trucks and buses). We have considered the Black Carbon as the tracer for diesel engines and biomass burning, being this last source associated not only with burning of sugar cane plantation and forest fires, but also with wood and charcoal used in restaurant and domestic cooking and residues burning. The responsibility of the vehicular emission to the fine particles has been maintained in approximately 50% of the mass. The soil resuspension was associated with 8% of the fine particles origin. We are presenting the data obtained from experiments performed from 1983 to 2014, not continuously and mainly performed in the winter time. It is a long period of data that is going to be considered. The previous results obtained with the application of PCA were compared to that obtained with PMF applied to the historical data collected at MASP, showing the evolution of the

    The evolution of the human diet over the past 10,000 years from a Paleolithic diet to our current modern pattern of intake has resulted in profound changes in feeding behavior. Shifts have occurred from diets high in fruits, vegetables, lean meats, and seafood to processed foods high in sodium and hydrogenated fats and low in fiber. These dietary changes have adversely affected dietary parameters known to be related to health, resulting in an increase in obesity and chronic disease, including cardiovascular disease (CVD), diabetes, and cancer. Some intervention trials using Paleolithic dietary patterns have shown promising results with favorable changes in CVD and diabetes risk factors. However, such benefits may be offset by disadvantages of the Paleolithic diet, which is low in vitamin D and calcium and high in fish potentially containing environmental toxins. More advantageous would be promotion of foods and food ingredients from our ancestral era that have been shown to possess health benefits in the form of functional foods. Many studies have investigated the health benefits of various functional food ingredients, including omega-3 fatty acids, polyphenols, fiber, and plant sterols. These bioactive compounds may help to prevent and reduce incidence of chronic diseases, which in turn could lead to health cost savings ranging from $2 to $3 billion per year as estimated by case studies using omega-3 and plant sterols as examples. Thus, public health benefits should result from promotion of the positive components of Paleolithic diets as functional foods.

  9. Second-hand tobacco smoke in Oklahoma: a preventable cause of morbidity and mortality and means of reducing exposure.

    2002-03-01

    Evidence has mounted in recent years establishing second-hand tobacco smoke exposure as a cause of morbidity and mortality in nonsmokers. The ratio of deaths is approximately one nonsmoker dying from illness caused by second-hand smoke exposure for every eight smokers who die from diseases caused by tobacco use. This is equivalent to about 750 nonsmoker deaths each year in Oklahoma caused by exposure to second-hand smoke. This article reviews the components of second-hand smoke, its health effects, its prevalence in Oklahoma, and the means of protecting children and nonsmoking adults from exposure. Oklahoma physicians are encouraged to advise their patients about the harmful effects of second-hand smoke and to actively support public policies that decrease exposure to second-hand smoke in public places and workplaces.

    In fluidised-bed gasification, various types of deposits and agglomerates may be formed by biomass ash in the bed, in upper zones of the reactor, for instance in cyclones. These may decisively hamper the operation of the process. The aim of the project was to obtain data on the detrimental fouling behaviour of the ash of different types of biomass in fluidised-bed gasification, and on the basis of these data to determine the process conditions and ways of preventing this kind of behaviour. Different types of biomass fuel relevant to energy production such as straw, wood residue were be used as samples. The project consisted of laboratory studies and fluidised-bed reactor tests including ash behaviour studied both in the bed and freeboard. In laboratory tests, the sample material was characterised as a function of different process parameters. In fluid-bed reactors, the most harmful biomasses were tested using process variables such as temperature, bed material and the gasification agents. Bubbling fluidised-bed gasification tests with wheat straw showed that agglomerates with different sizes and structures formed in the bed depending on the temperature, the feed gas composition and bed material. Agglomerates consisted of molten ash which sintered with bed material and other solids. In all BFB tests, freeboard walls were slicked by ash agglomerates (different amounts) which, however, were easily removable. The results of this project and the earlier pilot-scale gasification experience obtained with the same feedstocks showed that useful characteristic data about ash behaviour can be obtained using laboratory tests and small scale reactors.

    The German system to prevent, detect and respond to illicit uses of nuclear materials and radioactive sources consists of a variety of different elements: International and national laws and regulations covering safeguards, physical protection, and import/export control; Licensing and regulatory supervision of all activities related to nuclear materials and radioactive sources, including import and export; Responsibility of the licensee to ensure compliance with licensing conditions; sanctions; Law enforcement by police, security and customs authorities; prosecution and penalties; Detection of illicitly trafficked radioactive materials through intelligence and technical means; analysis capabilities; Response arrangements for normal and for severe cases of illicit use of nuclear materials; Participation in international programmes and POC-systems. Safeguards measures have been implemented in Germany in accordance with the Non- Proliferation Treaty and with safeguards agreements based on INFCIRC/153. As Germany is a member of the European Union, the Euratom Treaty and the Euratom-Ordinance Nr. 3227/76 together with the Verification Agreement between the IAEA, the European Commission and the European Member States have led to safeguards measures jointly implemented by the IAEA and by Euratom. The relevant international law for the physical protection of nuclear material in force in Germany is the Convention on the Physical Protection of Nuclear Material. The recommendations on physical protection objectives and fundamentals and on physical protection measures specified in INFCIRC/225/Rev. 4 have been taken into account in various national regulations pertaining to the national design basis threat, the physical protection of LWR nuclear power plants, of interim spent fuel storage facilities, of facilities containing category III material, of nuclear material and radioactive waste transports by road or railway vehicles, aircraft or sea vessels; additional guidelines

    This study was conducted to further assess the feasibility of vaccinating black-footed ferrets (Mustela nigripes) against plague (caused by the bacterium Yersinia pestis). On days 0 and 28, 17 postreproductive ferrets were immunized by subcutaneous injection with a recombinant fusion protein containing F1 and V antigens from Y. pestis. Another 17 animals received a placebo by the same route. Two weeks after the second immunization, mean antibody titers to Y. pestis F1 and V antigens were measured and found to be significantly higher in vaccinates than their preimmunization values (P plague by subcutaneous inoculation. Eleven of 16 vaccinates (69 percent) survived with no ill effects whereas all eight control animals died within 3a??6 days. Two months later, the 11 surviving vaccinates were challenged again by ingestion of a plague-infected mouse. None of the animals showed any ill effects and all survived. In contrast, seven control ferrets fed infected mice died within 2a??4 days, including one animal that did not actually ingest the mouse but was likely exposed to it. This study demonstrates that immunization of ferrets with the recombinant F1-V fusion protein can induce significant antibody responses and reduce their susceptibility to plague infection.

    This paper discusses the sources of radiation in the narrow perspective of radioactivity and the even narrow perspective of those sources that concern environmental management and restoration activities at DOE facilities, as well as a few related sources. Sources of irritation, Sources of inflammatory jingoism, and Sources of information. First, the sources of irritation fall into three categories: No reliable scientific ombudsman to speak without bias and prejudice for the public good, Technical jargon with unclear definitions exists within the radioactive nomenclature, and Scientific community keeps a low-profile with regard to public information. The next area of personal concern are the sources of inflammation. This include such things as: Plutonium being described as the most dangerous substance known to man, The amount of plutonium required to make a bomb, Talk of transuranic waste containing plutonium and its health affects, TMI-2 and Chernobyl being described as Siamese twins, Inadequate information on low-level disposal sites and current regulatory requirements under 10 CFR 61, Enhanced engineered waste disposal not being presented to the public accurately. Numerous sources of disinformation regarding low level radiation high-level radiation, Elusive nature of the scientific community, The Federal and State Health Agencies resources to address comparative risk, and Regulatory agencies speaking out without the support of the scientific community

    The US EPA is the lead Federal agency for emergency responses to unknown radiological materials, not licensed, owned or operated by a Federal agency or an Agreement state (Federal Radiological Emergency Response Plan, 1996). The purpose of EPA's clean materials programme is to keep unwanted and unregulated radioactive material out of the public domain. This is achieved by finding and securing lost sources, maintaining control of existing sources and preventing future losses. The focus is on both, domestic and international fronts. The domestic program concentrates on securing lost sources, preventing future losses, alternative technologies like tagging of radioactive sources in commerce, pilot radioactive source roundup, training programs, scrap metal and metal processing facilities, the demolition industry, product stewardship and alternatives to radioactive devices (fewer radioactive source devices means fewer orphan sources). The international program consists of securing lost sources, preventing future losses, radiation monitoring of scrap metal at ports and the international scrap metal monitoring protocol

    The artificial neural networks technology has been applied to reconstruct the neutrons spectra of two isotopic sources: {sup 252}Cf, and {sup 241}Am-Be. Also, this technology has been applied to obtain the effective dose, E, and the personal dose equivalents, Hp(10) and environmental, H *(10). To obtain the spectra and the doses only were used the count rates produced in a Bonner Spheres spectrometer with a scintillator of {sup 6}LiI(Eu) of 0.4 {phi} x 0.4 cm{sup 2}. The equivalent environmental dose and the spectra of the sources were also obtained by means of the reconstruction code BUNKIUT. When comparing the results obtained by means of both procedures it was found that they are consistent. (Author)

    Station "Khibiny", equipped with a powerful magnetohydrodynamic (MHD) generator and/or diesel generator, has been successfully used since 1976 to study the electrical conductivity of the Earth's crust in the northern part of the Baltic Shield. The present paper describes the techniques of measurement, data processing and interpretation of the five-component electromagnetic fields created by this source. A longitudinal conductance map for the upper 10 km of the Earth's crust has been constructed. Several blocks, with conductances varying from 0.1 to some thousands of Siemens, have been revealed on the Kola Peninsula, in northern Karelia and in northern Finland. The blocks of high conductance are connected with relatively young complexes of Early Proterozoic and Late Archean ages. In some places, they create thick and extensive conductive belts such as the Imandra-Varzuga and the Pechenga zones. More often, they appear in the shape of vast regions with enhanced conductivity (e.g., the granulite belts and the Allarechen region). The geoelectric cross-section of the Imandra-Varzuga ore-critical structure has been studied in detail, using the method of electromagnetic field migration. Its depth extent is approximately 10 km. Highly resistant blocks are associated with the most ancient geological units, of early Archean age. Resistant regions have been found in the Murmansk and Central Kola regions, as well as in the Kovdor massif and in the Central Finland granite area. These regions are the most promising ones for deep electromagnetic sounding of the lower crust and the upper mantle of the Earth.

    Background Except during a 1-year period when BCG vaccine was not routinely administered, annual coverage of infants with Bacillus Calmette-Guérin (BCG) in Kazakhstan since 2002 has exceeded 95%. BCG preparations from different sources (Japan, Serbia, and Russia) or none were used exclusively in comparable 7-month time-frames, September through March, in 4 successive years beginning in 2002. Our objective was to assess relative effectiveness of BCG immunization. Methods/Findings We compared outcomes of birth cohorts from the 4 time-frames retrospectively. Three cohorts received vaccine from one of three manufacturers exclusively, and one cohort was not vaccinated. Cohorts were followed for 3 years for notifications of clinical TB and of culture-confirmed TB, and for 21 months for TB meningitis notifications. Prevention effectiveness based on relative risk of TB incidence was calculated for each vaccinated cohort compared to the non-vaccinated cohort. Although there were differences in prevention effectiveness observed among the three BCG vaccines, all were protective. The Japanese vaccine (currently used in Kazakhstan), the Serbian vaccine, and the Russian vaccine respectively were 69%, 43%, and 22% effective with respect to clinical TB notifications, and 92%, 82%, and 51% effective with respect to culture confirmed TB. All three vaccines were >70% effective with respect to TB meningitis. Limitations Potential limitations included considerations that 1) the methodology used was retrospective, 2) multiple risk factors could have varied between cohorts and affected prevention effectiveness measures, 3) most cases were clinically diagnosed, and TB culture-positive case numbers and TB meningitis case numbers were sparse, and 4) small variations in reported population TB burden could have affected relative risk of exposure for cohorts.

The Japanese vaccine (currently used in Kazakhstan, the Serbian vaccine, and the Russian vaccine respectively were 69%, 43%, and 22% effective with respect to clinical TB notifications, and 92%, 82%, and 51% effective with respect to culture confirmed TB. All three vaccines were >70% effective with respect to TB meningitis. LIMITATIONS: Potential limitations included considerations that 1 the methodology used was retrospective, 2 multiple risk factors could have varied between cohorts and affected prevention effectiveness measures, 3 most cases were clinically diagnosed, and TB culture-positive case numbers and TB meningitis case numbers were sparse, and 4 small variations in reported population TB burden could have affected relative risk of exposure for cohorts. CONCLUSIONS/SIGNIFICANCE: All three BCG vaccines evaluated were protective against TB, and prevention effectiveness

    Except during a 1-year period when BCG vaccine was not routinely administered, annual coverage of infants with Bacillus Calmette-Guérin (BCG) in Kazakhstan since 2002 has exceeded 95%. BCG preparations from different sources (Japan, Serbia, and Russia) or none were used exclusively in comparable 7-month time-frames, September through March, in 4 successive years beginning in 2002. Our objective was to assess relative effectiveness of BCG immunization. We compared outcomes of birth cohorts from the 4 time-frames retrospectively. Three cohorts received vaccine from one of three manufacturers exclusively, and one cohort was not vaccinated. Cohorts were followed for 3 years for notifications of clinical TB and of culture-confirmed TB, and for 21 months for TB meningitis notifications. Prevention effectiveness based on relative risk of TB incidence was calculated for each vaccinated cohort compared to the non-vaccinated cohort. Although there were differences in prevention effectiveness observed among the three BCG vaccines, all were protective. The Japanese vaccine (currently used in Kazakhstan), the Serbian vaccine, and the Russian vaccine respectively were 69%, 43%, and 22% effective with respect to clinical TB notifications, and 92%, 82%, and 51% effective with respect to culture confirmed TB. All three vaccines were >70% effective with respect to TB meningitis. Potential limitations included considerations that 1) the methodology used was retrospective, 2) multiple risk factors could have varied between cohorts and affected prevention effectiveness measures, 3) most cases were clinically diagnosed, and TB culture-positive case numbers and TB meningitis case numbers were sparse, and 4) small variations in reported population TB burden could have affected relative risk of exposure for cohorts. All three BCG vaccines evaluated were protective against TB, and prevention effectiveness varied by manufacturer. When setting national immunization policy, consideration

  7. Measures to prevent, intercept and respond to illicit uses of nuclear material and radioactive sources. Proceedings

    International Nuclear Information System (INIS)

    2002-01-01

    As nuclear programmes have evolved, the quantities of nuclear material in use or storage, and the number of facilities operating or shut down has increased. In particular, the dismantling of nuclear weapons has resulted in greatly increased stockpiles of weapons usable plutonium and highly enriched uranium. Concern over the security of these and related materials has been further raised by the continued occurrence of cases of illicit trafficking. The risks are theft, leading to trafficking and possible illicit use, and sabotage which could lead to the creation of radiological hazards. The challenge is threefold: prevention, detection and interception, and response. Prevention starts with effective national systems for accountancy, control and protection. Detection and interception involves effective measures to combat illicit trafficking, and response requires planning for the consequences of theft and sabotage. Responsibilities in these fields are national, but nuclear security also has a powerful international dimension. The consequences of failures in national measures reach beyond national boundaries. The effectiveness of national nuclear security can be enhanced through international measures: through agreed international norms, standards and guides, through training and advice, through information exchange and the sharing of experience, and through developing common understandings and perceptions. The Stockholm Conference contributed by focusing on the threats, including terrorist, to nuclear and other radioactive materials; on how to assess them and on how to develop the appropriate security measures. National measures to protect nuclear material and facilities and the continuing development of international standards and obligations were described. The conference discussed the patterns and trends in the illicit trafficking of nuclear and other radioactive materials and national and international measures to combat such trafficking. Finally, it considered

    Objective: To investigate the effect of 3-year phased bans of the pesticides dimethoate and fenthion in 2008–2010, and paraquat in 2009–2011, on suicide mortality in Sri Lanka. Methods: Age-standardised overall, sex-specific, and method-specific suicide rates were calculated using Sri Lankan police...... data (1989–2015). Using negative binomial regression models, we estimated the change in the rate and number of suicide deaths in post-ban years (2011–15) compared to those expected based on pre-ban trends (2001–10). Findings: Overall suicide mortality dropped by 21% between 2011 and 2015, from 18.......3 to 14.3 per 100,000. The decline in pesticide suicides during this same period was larger than for overall suicides: from 8.5 to 4.2 per 100,000, a 50% reduction. This was accompanied by a smaller concurrent rise in non-pesticide suicide mortality with a 2% increase (9.9 to 10.1 per 100,000). In 2015...

    Although social media ubiquitously supplementstraditional information sources such as newspapers,magazines, radio, and television, investigation of onlinehealth information related to sun protection and skincancer prevention has been scarce and largely limitedto English language sources. Using the search terms"sun protection," "sunscreen," "skin cancer prevention,"tanning bed" and "vitamin D," we investigated 281YouTube videos presented in 6 languages: English,German, French, Spanish, Swedish, and Danish. Foreach video, we used a four-sectioned checklist toassess general information, popularity, expert drivenmeasures, and heuristic driven measures. Differencesbetween languages were detected: English languagevideos were most frequently viewed (median numberof views: 5488 compared to 248 -1591 in otherlanguages). Approximately 60% of videos revealednegative effects of solar ultraviolet (UV)-exposure.The majority of videos (75%) targeted adults. Videoson tanning beds and sunscreen contained false ormisleading information 40% and 20% of the time,respectively. We confirm observations made withrespect to other medical disciplines that the generalquality of YouTube contributions is often inferiorand does not deliver sustainable information. Othersources of information should be included whensearching for health information online.

    Source water areas are facing many potential water pollution risks. Risk assessment is an effective method to evaluate such risks. In this paper an integrated model based on k-means clustering analysis and set pair analysis was established aiming at evaluating the risks associated with water pollution in source water areas, in which the weights of indicators were determined through the entropy weight method. Then the proposed model was applied to assess water pollution risks in the region of Shiyan in which China's key source water area Danjiangkou Reservoir for the water source of the middle route of South-to-North Water Diversion Project is located. The results showed that eleven sources with relative high risk value were identified. At the regional scale, Shiyan City and Danjiangkou City would have a high risk value in term of the industrial discharge. Comparatively, Danjiangkou City and Yunxian County would have a high risk value in terms of agricultural pollution. Overall, the risk values of north regions close to the main stream and reservoir of the region of Shiyan were higher than that in the south. The results of risk level indicated that five sources were in lower risk level (i.e., level II), two in moderate risk level (i.e., level III), one in higher risk level (i.e., level IV) and three in highest risk level (i.e., level V). Also risks of industrial discharge are higher than that of the agricultural sector. It is thus essential to manage the pillar industry of the region of Shiyan and certain agricultural companies in the vicinity of the reservoir to reduce water pollution risks of source water areas.

    This study aimed to assess the relationship between rural or urban residence and having a usual source of care (USC), and the utilization of preventive dental checkups among adults. Cross-sectional analysis was conducted using data from the Medical Expenditure Panel Survey 2012. We performed a logit regression on the relationship between rural and urban residence, having a USC, and having at least 1 dental checkup in the past year, adjusting for sociodemographic characteristics and health status. After controlling for covariates, rural adult residents had significantly lower odds of having at least 1 dental checkup per year compared to their urban counterparts (odds ratio [OR] = 0.73, 95% confidence interval [CI]: 0.62-0.86, P rural and urban residents, having a USC was significantly associated with an 11% (95% CI = 9%-13%) increase in the probability of having a preventive dental checkup within a year. Individuals with a USC were more likely to obtain a preventive dental visit, with similar effects in rural and urban settings. We attributed the lower odds of having a checkup in rural regions to the lower density of oral health care providers in these areas. Integration of rural oral health care into primary care may help mitigate the challenges due to a shortage of oral health care providers in rural areas. © 2017 National Rural Health Association.

    2017-08-08

    Systematic identification of evidence in health policy can be time-consuming and challenging. This study examines three questions pertaining to systematic reviews on obesity prevention policy, in order to identify the most efficient search methods: (1) What percentage of the primary studies selected for inclusion in the reviews originated in scholarly as opposed to gray literature? (2) How much of the primary scholarly literature in this topic area is indexed in PubMed/MEDLINE? (3) Which databases index the greatest number of primary studies not indexed in PubMed, and are these databases searched consistently across systematic reviews? We identified systematic reviews on obesity prevention policy and explored their search methods and citations. We determined the percentage of scholarly vs. gray literature cited, the most frequently cited journals, and whether each primary study was indexed in PubMed. We searched 21 databases for all primary study articles not indexed in PubMed to determine which database(s) indexed the highest number of these relevant articles. In total, 21 systematic reviews were identified. Ten of the 21 systematic reviews reported searching gray literature, and 12 reviews ultimately included gray literature in their analyses. Scholarly articles accounted for 577 of the 649 total primary study papers. Of these, 495 (76%) were indexed in PubMed. Google Scholar retrieved the highest number of the remaining 82 non-PubMed scholarly articles, followed by Scopus and EconLit. The Journal of the American Dietetic Association was the most-cited journal. Researchers can maximize search efficiency by searching a small yet targeted selection of both scholarly and gray literature resources. A highly sensitive search of PubMed and those databases that index the greatest number of relevant articles not indexed in PubMed, namely multidisciplinary and economics databases, could save considerable time and effort. When combined with a gray literature search and

  13. Leuna methods of rapid emptying and pressure release of operating equipment filled with combustible liquids and gases, as means of prevention of spreading fires

    Energy Technology Data Exchange (ETDEWEB)

    1944-12-14

    At times, the considerable amounts of combustible liquids in the equipment during distillation, gas separation, scrubbing, etc. required special precautionary measures even under normal conditions. Obviously, such amounts of combustibles carried the danger of spreading fires from any disturbance, such as breaks in the piping, of the slides, explosions, and small fires. The past precautions taken in this matter had been fire extinguishers, construction of localizing compartments, spray systems, reduction of the amount of liquids, and other similar measures. However, such measures were of little use in case of an attack. Leuna decided to provide a means of rapid emptying with a simultaneous rapid exhausting of all equipment under danger. Releasing the pressure would prevent the formation of sharp-pointed flames with their devastating consequences. The installation consisted essentially of groups of valves (easily accessible), long pipe lines, storage farms for liquids, and a discharge into the air. Provisions were made for returning the materials under atmospheric pressure to prevent losses. The figures showed rapid emptying of scrubbers for circulating gas under high pressure, gasoline catchpot still, and pressure release of gas separation unit. These installations proved worthy and became a necessary part of operations. Four diagrams are given showing this installation. 4 diagrams

    Highlights: • Study of waste management in economically and socially deprived high-density housing. • Food waste segregation, prevention and recycling activities investigated. • Study involved a waste audit and household survey of 1034 households. • Populations in such areas are “hard-to-reach”. • Exceptional efforts and additional resources are required to improve performance. - Abstract: A waste audit and a household questionnaire survey were conducted in high-density housing estates in one of the most economically and socially deprived areas of England (Haringey, London). Such areas are under-represented in published research. The study examined source segregation, potential participation in a food waste segregation scheme, and food waste prevention activities in five estates (1034 households). The results showed that: contamination of recyclables containers was low; ca. 28% of the mixed residual waste’s weight was recyclable; food waste comprised a small proportion of the waste from these residents, probably because of their relatively disadvantaged economic circumstances; and the recycling profile reflected an intermittent pattern of behaviour. Although the majority of respondents reported that they would participate in a food waste separation scheme, the response rate was low and many responses of “don’t know” were recorded. Municipalities committed to foster improved diversion from landfill need to recognise that there is no “quick and easy fix”, regardless of local or national aspirations. Lasting and sustained behaviour change requires time and the quality of service provision and associated infrastructure play a fundamental role in facilitating residents to participate effectively in waste management activities that maximise capture of source-segregated materials. Populations in deprived areas that reside in high-rise, high-density dwellings are “hard-to-reach” in terms of participation in recycling schemes and exceptional

  18. Source inference of exogenous gamma-hydroxybutyric acid (GHB) administered to humans by means of carbon isotopic ratio analysis: novel perspectives regarding forensic investigation and intelligence issues.

    γ-Hydroxybutyric acid (GHB) is an endogenous short-chain fatty acid popular as a recreational drug due to sedative and euphoric effects, but also often implicated in drug-facilitated sexual assaults owing to disinhibition and amnesic properties. Whilst discrimination between endogenous and exogenous GHB as required in intoxication cases may be achieved by the determination of the carbon isotope content, such information has not yet been exploited to answer source inference questions of forensic investigation and intelligence interests. However, potential isotopic fractionation effects occurring through the whole metabolism of GHB may be a major concern in this regard. Thus, urine specimens from six healthy male volunteers who ingested prescription GHB sodium salt, marketed as Xyrem(®), were analysed by means of gas chromatography/combustion/isotope ratio mass spectrometry to assess this particular topic. A very narrow range of δ(13)C values, spreading from -24.81‰ to -25.06‰, was observed, whilst mean δ(13)C value of Xyrem(®) corresponded to -24.99‰. Since urine samples and prescription drug could not be distinguished by means of statistical analysis, carbon isotopic effects and subsequent influence on δ(13)C values through GHB metabolism as a whole could be ruled out. Thus, a link between GHB as a raw matrix and found in a biological fluid may be established, bringing relevant information regarding source inference evaluation. Therefore, this study supports a diversified scope of exploitation for stable isotopes characterized in biological matrices from investigations on intoxication cases to drug intelligence programmes.

    Latinos are the largest minority group in the United States and experience persistent disparities in access to and quality of health care. (1) To determine the relationship between nativity/immigration status and self-reported quality of care and preventive care. (2) To assess the impact of a usual source of health care on receipt of preventive care among Latinos. Using cross-sectional data from the 2007 Pew Hispanic Center/Robert Wood Johnson Foundation Hispanic Healthcare Survey, a nationally representative telephone survey of 4,013 Latino adults, we compared US-born Latinos with foreign-born Latino citizens, foreign-born Latino permanent residents and undocumented Latinos. We estimated odds ratios using separate multivariate ordered logistic models for five outcomes: blood pressure checked in the past 2 years, cholesterol checked in the past 5 years, perceived quality of medical care in the past year, perceived receipt of no health/health-care information from a doctor in the past year, and language concordance. Undocumented Latinos had the lowest percentages of insurance coverage (37% vs 77% US-born, P Undocumented Latinos also reported the highest percentage receiving no health/health-care information from their doctor (40% vs 20% US-born, P undocumented status was associated with lower likelihood of blood pressure checked in the previous 2 years (OR = 0.60; 95% CI, 0.43-0.84), cholesterol checked in the past 5 years (OR = 0.62; 95% CI, 0.39-0.99), and perceived receipt of excellent/good care in the past year (OR = 0.56; 95% CI, 0.39-0.77). Having a usual source of care increased the likelihood of a blood pressure check in the past 2 years and a cholesterol check in the past 5 years. In this national sample, undocumented Latinos were less likely to report receiving blood pressure and cholesterol level checks, less likely to report having received excellent/good quality of care, and more likely to receive no health/health-care information from doctors, even

    The responsibilities within natural hazards at local/regional levels involve citizens and volunteers as first actors of civil protection and territorial management. The prevention implicates the capacities of professional operators and technical volunteers, but the priority implies now the involvement and awareness of the citizens over the territory they inhabit. The involvement of population creates context-specific strategies of territorial surveillance and management, skipping the limit to face risks only when they have to bear impacts on their lives. MAppERS (Mobile Application for Emergency Response and Support) is a EU project (funded under programme 2013-2015 Humanitarian Aid and Civil Protection, ECHO A5) which empowers "crowd-sourced mappers" through smart phone applications and sensors, with geo-tagged information, detailed gathered parameters, field-check survey in a contest of geospatial response. The process of development includes feedback from citizens, involving them in training courses on the monitoring as long term objective (raising public awareness and participation). The project deals with the development and testing of the smart phone applications (module MAppERS-V for volunteers, module MAppERS-C for citizens) according to Android SDK environment. A first research described a desk-based investigation on consequences of disasters impacts and costs of prevention strategies in pilot countries.

    technological challenges of nuclear non-proliferation, which are directly connected with the central role of weapon-relevant materials, and it is trying to present practical solutions on a technical basis: - Discover paths for the disposal of existing amounts of nuclear weapon-relevant materials elaborating on the example of technically-based plutonium disposal options: central technical questions of the possible use of uranium-free inert matrix fuel (IMF) in currently used light water reactors will be addressed in order to clarify which advantages or disadvantages do exist in comparison to other disposal options. The investigation is limited on the comparison with one other reactor-based option, the use of uranium-plutonium mixed-oxide (MOX) fuels. - Analysis of proliferation relevant potentials of new nuclear technologies (accessibility of weapon materials): Exemplary investigation of spallation neutron sources in order to improve this technology by a more proliferation resistant shaping. Although they are obviously capable to breed nuclear weapon-relevant materials like plutonium, uranium-233 or tritium, there is no comprehensive analysis of nonproliferation aspects of spallation neutron sources up to now. Both project parts provide not only contributions to the concept of preventive arms control but also to the shaping of technologies, which is oriented towards the criteria of proliferation resistance.

    A "Community Control Programme of Hypertension" has been implemented in a Northern Italian population as part of an international co-operative pilot project promoted by World Health Organization. The programme was planned to last five years. Three years after the start we performed what we called a "capillary" screening in the community involved in the project. In fact a team of physicians and medical students moved about in the villages of the area where extemporary ambulances were set up with the aim of identifying new hypertensives, evaluating the state of the control of hypertension as compared with the situation at the outset of the study and, more generally, as a means of strengthening the ties between the project organization and the community. In doing so we also evaluated the feasibility of an alternative approach, based upon the cooperation with an organization outside the health service system, namely the Catholic Church, to achieve the set aims in a very religious population as ours. The parish priests of the villages did eagerly cooperate with our work both in the form of propaganda and in making available the parish buildings in which the ambulances were set up. We examined 1306 subjects (47.3% males), of whom 39.5% were hypertensives ("casual" blood pressure at or above 160 or 95 or treated). Of all the hypertensives, 28.6% were new hypertensives ("unaware"), 45.3% were being treated and 13.7% had a blood pressure lower than 160/95 mmHg while under treatment "effectively treated"); 16%, though, had blood pressure values at or above 200 or 120 mmHg. The state of control of hypertension was better in women and with increasing age. As compared with the findings at the outset of the study, 27,6% more "aware", 23.9% more treated and 9.6% more "effectively treated" hypertensives were found. Using the support of an alternative (non-medical) organization in a programme of preventive medicine in the community has proved to be, in our experience, a feasible

    MIT and PECO Energy have completed a detailed examination of the sources of forced outages at the Limerick Generating Station (LGS) Boiling Water Reactor Class IV (BWR IV) site over a five year period and contrasted that information to similar BWR IV utilities in the United States over the same period. Each forced outage was attributed to one system and assigned causal codes of equipment versus human factors and failure attributes such as weak design, poor craftsmanship, and worn parts. It was found that fifty four percent of the lost power at LGS was the result of Balance of Plant failures. Industry wide data identifies fifty nine percent of the lost power as attributed to Balance of Plant failures. Balance of Plant systems are those systems not included in the primary and safety related system category. Considering failure causal factors, forty six percent of the lost power at the utility under study was the result of equipment factors such as weak design or worn parts. Significantly, the study showed a high variance between those systems which caused significant forced outage at the two sister LGS units. This demonstrated the infrequent nature of plant forced outages within a given system. This was supported by the observation that dominant systems attributing to forced outage at LGS were not equally represented in industry data. It is suggested that for individual utilities to dramatically improve unit capability factors with regard to Balance of Plant systems, they must learn from industry wide experiences and develop cooperative means of exchanging lessons learned among similarly designed plants and systems. With the broad knowledge base of system failures, current designs must be frequently assessed and altered until each system poses an acceptable level of risk to generation capacity. (author)

    An amendment concerning the enforcement of the law on the prevention of radiation hazards due to radioisotopes, etc., and the medical service law enforcement regulations were promulgated on June 1, 2005. This amendment concerned international basic safety standards and the sealing of radiation sources. Sealed radiation sources ≤3.7 MBq, which had been excluded from regulation, were newly included as an object of regulation. Investigation of the single photon emission computed tomography (SPECT) system instituted in hospitals indicated that almost all institutions adhere to the new amendment, and the calibration source, the checking source, etc., corresponding to this amendment were maintained appropriately. Any institutions planning to return sealed radioisotopes should refer to this report. (author)

    EPA believes that the most effective and equitable means of assuring viability of this infrastructure is through environmentally preferred pollution prevention approaches especially through application of Municipal Water Pollution Prevention (MWPP). These approaches may enhance worker safety, improve the usability of sludge, increase the ability for local community expansion, and reduce operation and compliance costs. State-based municipal pollution prevention programs focus attention on a series of actions to prevent pollution in advance rather than taking more expensive corrective actions. MWPP encourages resource conservation to reduce water and energy use, appropriate pricing, toxicity reductions at the source, BOD reductions, recycling, proper treatment of wastes, and beneficial uses of sludge

    AIMS: Evidence strongly suggests that depression is a common complication of Type 2 diabetes mellitus. However, there is considerable room to improve the effectiveness of pharmacological antidepressant agents, as in only 50-60% of the depressed subjects with diabetes does pharmacotherapy lead...... to remission of depression. The aim of the present paper was to review whether polyunsaturated fatty acids (PUFA) of the omega-3 family could be used for the prevention and treatment of depression in Type 2 diabetes. METHODS: MEDLINE database and published reference lists were used to identify studies...... that examined the associations between omega-3 PUFA and depression. To examine potential side-effects, such as on glycaemic control, studies regarding the use of omega-3 supplements in Type 2 diabetes were also reviewed. RESULTS: Epidemiological and clinical studies suggest that a high intake of omega-3 PUFA...

    The key point in the state-of-the-art in the tsunami forecasting is constructing a reliable tsunami source. In this study, we present an application of the original numerical inversion technique to modeling the tsunami sources of the 16 September 2015 Chile tsunami. The problem of recovering a tsunami source from remote measurements of the incoming wave in the deep-water tsunameters is considered as an inverse problem of mathematical physics in the class of ill-posed problems. This approach is based on the least squares and the truncated singular value decomposition techniques. The tsunami wave propagation is considered within the scope of the linear shallow-water theory. As in inverse seismic problem, the numerical solutions obtained by mathematical methods become unstable due to the presence of noise in real data. A method of r-solutions makes it possible to avoid instability in the solution to the ill-posed problem under study. This method seems to be attractive from the computational point of view since the main efforts are required only once for calculating the matrix whose columns consist of computed waveforms for each harmonic as a source (an unknown tsunami source is represented as a part of a spatial harmonics series in the source area). Furthermore, analyzing the singular spectra of the matrix obtained in the course of numerical calculations one can estimate the future inversion by a certain observational system that will allow offering a more effective disposition for the tsunameters with the help of precomputations. In other words, the results obtained allow finding a way to improve the inversion by selecting the most informative set of available recording stations. The case study of the 6 February 2013 Solomon Islands tsunami highlights a critical role of arranging deep-water tsunameters for obtaining the inversion results. Implementation of the proposed methodology to the 16 September 2015 Chile tsunami has successfully produced tsunami source model

    The appearance of orphan sources in steelmaking facilities has become a fact nowadays. Radiation sources, hidden within the scrap, may come into the scrap yard and become part of the melting. As a result, dispersion of the radioactive material that makes up the source takes place throughout the facility. The University of the Basque Country (U.P.V.-E.H.U.), in collaboration with the Empresa Nacional de Residuos Radiactivos, S.A. (E.N.R.E.S.A.) and the Consejo de Seguridad Nuclear (C.S.N.), has carried out a Research Project to analyze this accidental melting of radioactive sources in electric arc furnaces (E.A.F.). The whole steelmaking process can be analyzed in several discrete phases. Radioactive sources that may be incorporated to this process will be exposed to the different critical conditions prevailing during each phase. In this sense, Computational Fluid Dynamics (C.F.D.) has been used in order to recreate such conditions and so, determine the characteristics of the dispersion of radioactivity. Two different situations have been studied in detail using C.F.D. techniques: thermal conditions around a scrap-basket that contains the source just before entering the furnace and the deposition of steelmaking dust containing 137 Cs on the inner surface of flue pipes. Before entering the furnace, scrap is usually placed inside a basket that remains above the furnace during some time. Once the furnace is open the scrap is dropped into the furnace to complete the loading process. C.F.D. techniques have been used to analyze the thermal conditions around the basket in order to assess the possibility of a break of the radioactive source hidden within the scrap, concluding that commercial sources will maintain their integrity during the whole loading process. On the other hand, after entering the furnace dispersion of the radioactive material will take place. Physical and chemical properties of the active elements (chemical form, composition, melting point, etc

    2015-01-01

    This research analyses the effectiveness of the water-to-cement ratio (w/c), fly ash and a calcium nitrite based corrosion inhibitor to prevent the corrosion of reinforcing steel embedded in high performance concrete. The interactive effect between the inhibitor and fly ash was evaluated because the occurrence of a negative effect when both ingredients are added together in a concrete mixture has been reported. All the concrete mixtures studied in this investigation had 8.2% of silica fume. Twenty seven prismatic concrete specimens were fabricated with dimensions of 55 × 230 × 300 mm each containing two steel rods embedded for the purpose of corrosion monitoring. The specimens were exposed to a simulated marine environment with two daily cycles of wetting and drying for one year. To evaluate the deterioration of the specimens corrosion potentials and linear polarization resistance tests were carried out. The results indicate that the use of a low w/c, the addition of fly ash and the addition of the corrosion inhibitor contributed to the reduction of the corrosion of steel in the concrete specimens. The results further suggest that the combination of fly ash and corrosion inhibitor does not promote the deterioration of the concrete matrix

    The accurate evaluation of the radiation burden associated with radiation absorbed doses to the skin of the extremities during the manipulation of radioactive sources is a critical issue in operational radiological protection, deserving the most accurate calculation approaches available. Monte Carlo simulation of the radiation transport and interaction is the gold standard for the calculation of dose distributions in complex geometries and in presence of extended spectra of multi-radiation sources. We propose the use of Monte Carlo simulations in GAMOS, in order to accurately estimate the dose to the extremities during manipulation of radioactive sources. We report the results of these simulations for 90Y, 131I, 18F and 111In nuclides in water solutions enclosed in glass or plastic receptacles, such as vials or syringes. Skin equivalent doses at 70 μm of depth and dose-depth profiles are reported for different configurations, highlighting the importance of adopting a realistic geometrical configuration in order to get accurate dosimetric estimations. Due to the easiness of implementation of GAMOS simulations, case-specific geometries and nuclides can be adopted and results can be obtained in less than about ten minutes of computation time with a common workstation.

    Full Text Available The researchers performed a comparative evaluation of the clinical and microbiological efficacy of the pneumo 23, ACT HIB and Grippol vaccine combination for the prevention of the recurrent respiratory diseases among children from the closed children's facilities if compared with mono immunization by Grippol. The open research included 60 children (average age was 3,33 ± 0,21 years with recurrent respiratory diseases. Depending on the results of the microbiological examination, the children were divided into 2 groups. The 1st group consisted of 35 children with negative bacteriological result, while the 2nd group consisted of the haemophilus influenzae and pneumococcus carriers. The children from the 1st group were divided into 2 subgroups: the 1st subgroup included 13 children vaccinated with pneumo 23 and Grippol, 22 children from the 2nd subgroup were immunized with Grippol only. 15 patients from the 2nd group were immunized against flu, pneumococcus and hemophilic infections (1st subgroup; while the 2nd subgroup (n = 10 was composed of children vaccinated with Grippol only. The carrier level was evaluated in dynamics in 1 and 6 months accordingly. the number of the acute respiratory diseases, their structure, the number of antibiotic courses and disease duration — in 12 months, immune status — in 6 months after immunization. Within the general sample, the carrier level made up 36,7% with the prevailing capsular variant of h. influenzae b type. The share of h. influenzae b carriers reduced by 2,5 times to make up 6,7% after immunization with 3 vaccines. Children vaccinated with Grippol only showed no reliable differences with regards to the discharge of haemophilus influenzae before and after vaccination in the observation dynamics. Vaccination against flu contributed to reduction of pneumonia sickness rate by 3 times, pharyngitis sickness rate by 2 times, laryngotracheitis sickness rate by 2,3 times, while the total number of the acute

    The paper discusses the role of argumentative competencies for the achievement of patient engagement through communication in doctor-patient consultations. The achievement of patient engagement is being proposed by recent studies as a condition that can facilitate in particular patient adherence, which involves behavior change. One obstacle to behavior change that has been observed is reactance, i.e., resistance to persuasive messages when a threat to freedom is perceived. In the medical field, reactance theory has been mostly applied in the field of mental health, less frequently to understand non-adherence in general. However, a few studies have revealed that reactance can actually explain in part the motives behind non-adherence. These studies propose that the arousal of reactance could be limited or prevented by adopting relational measures aimed at giving patients the feeling that they still hold some control over the process of care and that the "impositions" on their freedoms are acceptable because they have had the opportunity to decide about them. However, they do not discuss how these strategies should be operationalized at the dialogical level. A debated issue in the study of reactance is the role played by knowledge. It seems that pure information regarding an issue is likely to represent a threat in itself. Complementary to this is the finding that quality of argument does not impact on the degree of reactance. These findings pose a problem in view of the goal of patient education, itself considered as a necessary premise for any process of patient engagement and adherence. It seems necessary to move away from a conception of education as mere transmission of information and look for more effective ways of transferring knowledge to patients. With regard to this issue, the paper argues that useful insights can be found in studies on science education, in which it is shown experimentally that argumentative processes favor learning and understanding

    Background: Debilitating brain injury occurs in 1.6–5 % of patients undergoing cardiac surgery with cardiopulmonary bypass. Diffusion-weighted magnetic resonance imaging studies have reported stroke-like lesions in up to 51 % of patients after cardiac surgery. The majority of the lesions seem...... with coronary vessel and/or valve disease and who are undergoing cardiac surgery with the use of cardiopulmonary bypass. Patients are stratified by age and surgical procedure and are randomised 1:1 to either an increased mean arterial pressure (70–80 mmHg) or ‘usual practice’ (40–50 mmHg) during cardiopulmonary...... bypass. The cardiopulmonary bypass pump flow is fixed and set at 2.4 L/minute/m2 body surface area plus 10–20 % in both groups. The primary outcome measure is the volume of the new ischaemic cerebral lesions (in mL), expressed as the difference between a baseline, diffusion-weighted, magnetic resonance...

  3. Consolidation and compaction as a means to prevent settlement of bentonite/sandy silt mixes for use in waste disposal sites

    The texture of the local Los Alamos tuff is that of a sandy silt with a high hydraulic conductivity. The permeability is dramatically decreased by addition of small amounts of bentonite. The coefficient of consolidation for bentonite/sandy silt ratios decreases inversely proportional with the square of that ratio, whereas the compression index, the swelling index, and the permeability change index increase with increasing bentonite ratio. A strong relationship also exists between the void ratio and the logarithm of the applied stress for any given bentonite ratio. The empirical linear relationship between the void ratio and the logarithm of the applied stress, developed by Taylor, is excellent and enables us to limit the evaluation of conductivity at any void ratio to the measurement of the initial and the desired void ratio, the initial conductivity, and the permeability change index. The decrease in void ratio caused by consolidation or natural compaction of the mixes are scrutinized. Examples of expected settlement and subsidence are calculated based on the known geotechnical characteristics of bentonite/sandy silt mixes. Remedial actions, i.e., means to limit the amount of settlement, are considered. We finally discuss our field experiment, which studies the influence of subsidence on layered systems in general and on biobarriers in particular. 15 refs., 5 tabs

    2001-01-01

    Full text: Countries like Russia, which have a large nuclear industry, export a significant number of radioactive sources and substances. Some of them are nuclear material. In general, it is the task of the customs inspectors to verify that the content of the shipment is in agreement with the declaration (as safeguards inspectors verify operators declarations). In case of other goods, this is easy. The consignment can be opened and the content can be seen and compared with the declaration. In the case of radioactive shipments this cannot be done. The radioactive substance is in a shielded container and opening is often only possible in a hot cell. Opening of the package and measurement of the removed source in presence of the customs inspector is impossible because the customs control begins only after the declaration has been registered. Therefore, the Russian customs authorities have contracted a company to develop a gamma spectrometer, which can be used to verify the source, even if inside the shielded shipping container. Throughout the country - where many shipments or receivables take place - there are 18 customs offices, equipped with gamma spectrometers and special software. If a container arrives for customs inspection, its design is called from a database. Then the gamma spectrum outside the container is measured and the measured gamma peak energy and intensity is compared with the expected, which is calculated by software based on the design information of the container. This approach works well. Several cases were already discovered in Russia, where there were attempts to use legal shipments for smuggling radioactive sources. I would like to mention some technical problems concerning control of legal export and import of radioactive sources: a) There are not enough commercial suppliers which offer the needed equipment; because of lack of competition prices for the equipment are too high. b) Presently available equipment is mainly based on HPGE cooled

  5. On the use of mean groundwater age, life expectancy and capture probability for defining aquifer vulnerability and time-of-travel zones for source water protection.

    Protection and sustainability of water supply wells requires the assessment of vulnerability to contamination and the delineation of well capture zones. Capture zones, or more generally, time-of-travel zones corresponding to specific contaminant travel times, are most commonly delineated using advective particle tracking. More recently, the capture probability approach has been used in which a probability of capture of P=1 is assigned to the well and the growth of a probability-of-capture plume is tracked backward in time using an advective-dispersive transport model. This approach accounts for uncertainty due to local-scale heterogeneities through the use of macrodispersion. In this paper, we develop an alternative approach to capture zone delineation by applying the concept of mean life expectancy E (time remaining before being captured by the well), and we show how life expectancy E is related to capture probability P. Either approach can be used to delineate time-of-travel zones corresponding to specific travel times, as well as the ultimate capture zone. The related concept of mean groundwater age A (time since recharge) can also be applied in the context of defining the vulnerability of a pumped aquifer. In the same way as capture probability, mean life expectancy and groundwater age account for local-scale uncertainty or unresolved heterogeneities through macrodispersion, which standard particle tracking neglects. The approach is tested on 2D and 3D idealized systems, as well as on several watershed-scale well fields within the Regional Municipality of Waterloo, Ontario, Canada. Copyright © 2011 Elsevier B.V.

    Metagenomic next-generation sequencing (mNGS) has been used to uncover unusual causes of infectious diseases but has not been used routinely for the investigation of putative nosocomial outbreaks. Here, we describe the use of mNGS during investigation of a cluster of human rhinovirus (HRV)-positive infections on a high-risk pulmonary ward. We performed mNGS on 6 midnasal turbinate swabs from 4 case-patients and 10 swabs from 9 control outpatients that tested positive for enterovirus/rhinovirus by the FilmArray system. HRV reads were recovered in 15 (94%) of the 16 samples sequenced. Phylogenetic analysis of HRV whole genomes from the 4 case-patients and 5 outpatient controls along with partial genomes from additional outpatient controls revealed that isolates from the case-patients were not directly related and that the 2 closest case HRV genomes had an estimated time to most recent common ancestor of 172 years. Our turnaround time from receipt of the sample to phylogenetic analysis was 24 hours. We found the use of mNGS downstream of a rapid polymerase chain reaction respiratory panel during an investigation of 4 hospital-acquired rhinovirus infections to rapidly dispel concern of a single-source transmission event. © The Author 2017.

    2013-01-01

    Many rural areas in the United States and throughout much of the postindustrial world are undergoing significant ecological, socioeconomic, and political transformations. The migration of urban and suburban dwellers into rural areas has led to the subdivision of large tracts of land into smaller parcels, which can complicate efforts to govern human-environmental problems. Non-point source (NPS) pollution from private rural lands is a particularly pressing human-environmental challenge that may be aggravated by changing land tenure. In this article, I report on a study of the governance and management of sediment (a common NPS pollutant) in the North Coastal basin of California, a region undergoing a transition from traditional extractive and agricultural land uses to rural residential and other alternative land uses. I focus on the differences in the governance and management across private timber, ranch, residential, vacation, and other lands in the region. I find that (1) the stringency and strength of sediment regulations differ by land use, (2) nonregulatory programs tend to target working landscapes, and (3) rural residential landowners have less knowledge of sediment control and report using fewer sediment-control techniques than landowners using their land for timber production or ranching. I conclude with an exploration of the consequences of these differences on an evolving rural landscape.

  8. Neural congruency effects in the multi-source interference task vanish in healthy youth after controlling for conditional differences in mean RT.

    Full Text Available According to the conflict monitoring model of cognitive control, reaction time (RT in distracter interference tasks (e.g., the Stroop task is a more precise index of response conflict than stimulus congruency (incongruent vs. congruent. The model therefore predicts that RT should be a reliable predictor of activity in regions of the posterior medial frontal cortex (pMFC that are posited to detect response conflict. In particular, pMFC activity should be (a greater in slow-RT than in fast-RT trials within a given task condition (e.g., congruent and (b equivalent in RT-matched trials from different conditions (i.e., congruent and incongruent trials. Both of these effects have been observed in functional magnetic resonance imaging (MRI studies of adults. However, neither effect was observed in a recent study of healthy youth, suggesting that (a the model does not accurately describe the relationship between RT and pMFC activity in this population or (b the recent study was characterized by high variability due to a relatively small sample size. To distinguish between these possibilities, we asked a relatively large group of healthy youth (n = 28 to perform a distracter interference task - the multi-source interference task (MSIT - while we recorded their brain activity with functional MRI. In this relatively large sample, both of the model's predictions were confirmed. We conclude that the model accurately describes the relationship between pMFC activity and RT in healthy youth, but that additional research is needed to determine whether processes unrelated to response conflict contribute to this relationship.

    Computed tomography (CT) of the medial clavicular epiphysis has been well established in forensic age estimations of living individuals undergoing criminal proceedings. The present study examines the influence of the examiner's qualification on the determination of the clavicular ossification stage. Additionally, the most frequent sources of error made during the stage assessment process should be uncovered. To this end, thin-slice CT scans of 1,420 clavicles were evaluated by one inexperienced and two experienced examiners. The latter did the evaluations in consensus. Two classification systems, a five-stage system and a substaging system for the main stages 2 and 3, were used. Prior to three of his six assessment sessions, the inexperienced examiner was specifically taught staging of clavicles. Comparison of the examiners' results revealed increasing inter- and intraobserver agreements with increasing state of qualification of the inexperienced examiner (from κ= 0.494 to 0.674 and from κ= 0.634 to 0.783, respectively). The attribution of a not-assessable anatomic shape variant to an ossification stage was identified as the most frequent error during stage determination (n= 349), followed by the overlooking of the epiphyseal scar defining stage 4 (n= 144). As to the clavicular substages, classifying substage 3a instead of 3b was found to be the most frequent error (n= 69). The data of this study indicate that κ values must not be considered as objective measures for inter- and intraobserver agreements. Furthermore, a high degree of specific qualification, particularly the knowledge about the diversity of anatomic shape variants, appears to be mandatory and indispensable for reliable evaluation of the medial clavicular epiphysis.

    The population of Paracatu is at risk of Arsenic (As) exposure associated with long-term exploration of the largest open pit gold mine in Brazil. As part of the interdisciplinary research "The Paracatu project: Arsenic environmental contamination and human health risks assessment in Paracatu-MG", carried out between 2011 and 2013, we used data disaggregated by gender to identify the sources of As-related information being accessed by inhabitants of Paracatu and to examine if access to these sources was correlated to awareness of As health effects and adoption of behaviors to reduce risk of As exposure. Semi-structured, face-to-face interviews were carried out with 460 participants (294 women and 166 men) to collect data on respondent's socio-demographic characteristics, use of mass media and social communication networks as sources of information on As issues, the trustworthiness of these information sources, awareness of As health effects, and adoption of behaviors to reduce As exposure. For both men and women, interpersonal communication was used and trusted more frequently than mass media to obtain information on As. Discussion of As issues occurred preferentially among individuals of the same gender and was associated with awareness of As health risks. There are marked differences in variables correlated with the adoption of behaviors to reduce the risk of As exposure between men and women. Discussing As issues with women was associated with adoption of risk-reduction practices for both genders. In contrast, men who discuss As issues with other men were less likely to adopt As exposure prevention behaviors. Finally, adoption was associated with awareness of As health effects for women, but this was not the case for men. Policy implications for decision makers, practitioners and researchers are discussed, based on concrete examples of how gender-specific approaches can effectively guide the formulation and implementation of health promotion campaigns and

  13. Meaning in mathematics education

    Valero, Paola; Hoyles, Celia; Skovsmose, Ole

    2005-01-01

    What does it mean to know mathematics? How does meaning in mathematics education connect to common sense or to the meaning of mathematics itself? How are meanings constructed and communicated and what are the dilemmas related to these processes? There are many answers to these questions, some of which might appear to be contradictory. Thus understanding the complexity of meaning in mathematics education is a matter of huge importance. There are twin directions in which discussions have developed - theoretical and practical - and this book seeks to move the debate forward along both dimensions while seeking to relate them where appropriate. A discussion of meaning can start from a theoretical examination of mathematics and how mathematicians over time have made sense of their work. However, from a more practical perspective, anybody involved in teaching mathematics is faced with the need to orchestrate the myriad of meanings derived from multiple sources that students develop of mathematical knowledge.

  14. Australian governments' spending on preventing and responding to drug abuse should target the main sources of drug-related harm and the most cost-effective interventions.

    Science.gov (United States)

    2011-01-01

    A notable feature of Australian drug policy is the limited public and professional attention given to the financial costs of drug abuse and to the levels and patterns of government expenditures incurred in preventing and responding to this. Since 1991, Collins and Lapsley have published scholarly reports documenting the social costs of drug abuse in Australia and their reports also contain estimates of governments' drug budgets: revenue and expenditures. They show that, in 2004-2005, Australian governments expended at least $5288 million on drug abuse, with 50% of the expenditure directed to preventing and dealing with alcohol-related problems, 45% to illicit drugs and just 5% to tobacco. Some 60% of the expenditure was directed at drug crime and 37% at health interventions. This pattern of resource allocation does not adequately reflect an evidence-informed policy orientation in that it largely fails to focus on the drug types that are the sources of the most harm (tobacco and alcohol rather than illicit drugs), and the sectors for which we have the strongest evidence of the cost-effectiveness of the available interventions (treatment and harm reduction rather than legislation and law enforcement). The 2010-2014 phase of Australia's National Drug Strategy should include incremental changes to the resource allocation mix, and not simply maintain the historical resource allocation formulae. © 2010 Australasian Professional Society on Alcohol and other Drugs.

  15. GREENHOUSE GASES AND MEANS OF PREVENTION

    2013-09-01

    Full Text Available The greenhouse effect can be defined as the consequence of increased heating of the Earth's surface, as well as the lower atmosphere by carbon dioxide, water vapor, and other trace amounts gases. It is well-known that human industrial activities have released large amounts of greenhouse gases in the atmosphere, about 900 billion tons of carbon dioxide, and it is estimated that up to 450 billion are still in the atmosphere. In comparison to greenhouse gases water vapor is one of the greatest contributors to the greenhouse effect on Earth. Many projects, as does the PURGE project, have tendences to build on the already conducted research and to quantify the positive and negative impacts on health and wellbeing of the population with greenhouse gas reduction strategies that are curently being implemented and should be increasingly applied in various sectors and urban areas, having offices in Europe, China and India.

    The purpose of this study was to examine where young adults were obtaining their HIV prevention information, and determine if there were consumption preferences based on gender and race/ethnicity. We conducted a series of race/ethnic and gender-concordant 2-hour focus groups, and qualitative analyses identified common domains. Sixty adolescents attended 6 focus groups. Findings revealed that primary informational sources were television and advertisements, educational settings, community health care centers, and family and friends. However, television commercials and advertisements were viewed as an ineffective approach, with mistrust of the "mainstream" media being very high for Black males. Recommendations centered on the need for more realistic scenarios related to living with HIV by other adolescents, greater parental involvement with HIV education, especially for minority youth, and the use of social media. Special attention should be given to the importance of social media for adolescents, and how the fear of HIV-related stigma influences HIV information consumption patterns among males.

    Sustainable use of resources worldwide, protection of the global climate, and enhanced energy efficiency are important challenges for Germany in the 21st century. A key element is the energy turnaround by enhanced use of renewable energy sources, especially in the private sector. The publication presents an acceptance model relating to this context; it is based on the three-component attitude theory and supplemented by concrete, behaviour-related acceptance of use. Statistical methods of verification showed that acceptance in attitude is the necessary condition for acceptance of action, which in turn is the necessary condition for acceptance of use. This means that acceptance in attitude will be the most common type of acceptance and acceptance of use the least common one. On the basis of the acceptance model and of other active and passive variables, a two-stage market segmentation and a cluster analysis were carried out in order to identify four different lifestyle types that are target groups for renewable energy sources. Among the active variables of the private end consumers were personality characteristics, personal values, technology affinity, thriftiness, environmental awareness and environmental behaviour. Descriptive or passive variables were recreational activities, media consumption, orientation in style and taste, and demographic characteristics. (orig./RHM)

    2008-01-01

    Full Text Available As the accumulation of PCDDs/Fs in the natural environment poses a great threat, and the pollution of the environment with these highly toxic compounds from various emitters needs to be prevented, many countries have conducted an inventory of industrial sources and their emissions in order to obtain better insight into the share of particular sources in the total emission of PCDDs/Fs and to develop strategies to reduce these emissions.Metallurgical processes like sintering of iron ore, production of steel and non-ferrous and light metals from scrap material belong to a group of stationary PCDDs/Fs emitters and their share in the total PCDDs/Fs emission into the environment is very significant. The relative significance of particular metallurgical processes varies from country to country, depending on the nature of a particular process, installed capacities and annual output levels.As the modern approach to observing the environment includes preventive measures, as opposed to corrective post-event measures that were common practice in the past, the owners/operators of metallurgical processes are developing and introducing pollution monitoring and surveillance systems, based on which they take appropriate measures.One of the frequently applied measures is to build and implement the ISO 14001 environmental management system that very efficiently runs production processes along with maintenance of environmental protection on a daily basis. Since the adoption of the ISO 14001 environmental management system is a voluntary decision to be made by each organization, in 1996 the European Union adopted, for the purpose of environmental protection and pollution prevention, the Directive 96/61 EC or IPPC Directive on Integrated Pollution Prevention and Control (IPPC requiring from industrial installations, depending on their type and output level, to obtain environmental permits to run production processes using best available techniques, thus maintaining

    Non point source pollutants, such as pesticides and fertilizers derived from agricultural activities, are recognized as an important threat to environment and human health. To prevent the adverse effects of these agrochemicals it is necessary to provide growers and decision makers with easy-to-use information. Attempts have been made to put information on pesticides environmental and health effects into a formula that could summarize, in a single number, these effects. However a single number could be misleading because of the lack of information on chemical-physical parameters and the difficulty to evaluate the relative importance of various environmental and health effects. As an alternative it is here proposed an approach based on schedule containing information, for each pesticides, such as short and long term effects on human health, environmental fate and degradation time, capacity to bio accumulate, toxicity of degradation products. Using information in the schedule, decision makers could make more circumstantiate choices and could program the best agricultural actions under particular environmental circumstances with less impact on man and environment. [Italian] L'inquinamento diffuso derivante dall'uso dei fertilizzanti e dei pesticidi in agricoltura, rappresenta un rischio rilevante per l'ambiente e la salute umana. Al fine di prevenire tale rischio e' necessario fornire a coloro che gestiscono e pianificano le attivita' agricole informazioni facilmente comprensibili, mirate a ridurre o eliminare gli effetti indesiderati derivanti dai prodotti agrochimici. Tentativi sono stati fatti per sviluppare metodologie che sintetizzino queste informazioni in un indice numerico in modo da stilare una graduatoria di pericolosita' dei singoli prodotti. Si propone, in questo lavoro, un approccio basato sulla elaborazione di schede, per ogni principio attivo, che contengono una serie di informazioni quali gli effetti a breve e lungo termine

    Cryptogenic ischemic strokes constitute 20-30% of ischemic strokes, the majority of which are embolic strokes of undetermined source. The standard preventive treatment in these patients is usually acetylsalicylic acid. The Randomized, double-blind, Evaluation in secondary Stroke Prevention comparing the EfficaCy and safety of the oral Thrombin inhibitor dabigatran etexilate vs. acetylsalicylic acid in patients with Embolic Stroke of Undetermined Source (RE-SPECT ESUS) is designed to determine whether the oral thrombin inhibitor dabigatran, taken within three-months after embolic stroke of undetermined source, is superior to acetylsalicylic acid for prevention of recurrent stroke and to characterize the safety of dabigatran in this setting. Prospective, randomized, double-blind, multicenter trial in approximately 6000 patients and 550 centers with embolic stroke of undetermined source. Subjects are randomized to dabigatran or acetylsalicylic acid and treated for an expected minimum of six-months and up to approximately three-years. It is an event-driven trial aiming for 353 adjudicated primary outcome events. The primary efficacy outcome is time to first recurrent stroke (ischemic, hemorrhagic, or unspecified). Key secondary outcomes are time to first ischemic stroke and time to first occurrence in the composite outcome of nonfatal stroke, nonfatal myocardial infarction, and cardiovascular death. The primary safety outcome is major hemorrhage, including symptomatic intracranial hemorrhage. Acetylsalicylic acid is the most common antithrombotic given to patients with embolic strokes of undetermined source to reduce recurrence risk. This trial will determine whether anticoagulation with dabigatran is more effective than acetylsalicylic acid, and acceptably safe. © 2015 World Stroke Organization.

    Full Text Available Este trabalho objetiva discutir os sentidos produzidos acerca do consumo de substâncias psicoativas por usuários do Programa de Prevenção e Tratamento de Alcoolismo e outras Dependências, implantado, em 1993, no ambulatório do Centro de Saúde de Pirangi da Secretaria Municipal de Saúde de Natal/RN. Foram realizadas 14 entrevistas com usuários de quatro categorias: em tratamento; de alta; os que entraram no programa de forma voluntária; os que entraram de forma compulsória. As falas foram analisadas segundo a perspectiva da análise do discurso. Os resultados indicam que as substâncias mais consumidas são o álcool e a maconha. Os fatores motivadores do uso de drogas são: a fuga dos problemas; b curiosidade; c influência dos amigos; d insatisfação com a vida; e busca de prazer e fraqueza pessoal; sinalizando a complexidade e a multideterminação do uso de drogas. O uso de drogas, para os usuários, apresenta tanto um sentido negativo, associado aos danos físicos e sociais decorrentes do uso, quanto um sentido positivo, relacionado com a sensação de bem-estar sentida e "esquecimento" e fuga dos problemas. Outro aspecto observado nas entrevistas revela representações construídas socialmente em torno das pessoas que usam drogas, tidas como "marginais", "fora da lei", prevalecendo uma visão punitiva e discriminatória da questão.The purpose of the study was to identify the meaning of drug consumption in patients of the Alcohol and Drug Prevention and Treatment Program at the Pirangi Health Center in Natal, RN.

    The aim of this paper is to present the Brazilian experience to encourage renewable sources of power generation through the auctions into the Regulated Environment of Contracting. These auctions are subdivided into auctions of existing plants, new plants, alternative sources and structural plants. In this process we observe the structure of the mechanism for contracting new projects of renewable sources without neglecting the low tariffs issues. Thus, the auctions of electricity in Brazil is an alternative to be considered in an attempt to group market mechanisms, low tariffs and incentives to renewable sources of generation. (author)

    2014-12-01

    Congenital cytomegalovirus (CMV) is a leading cause of permanent disability in children. The main source of maternal infection is from contact with young children. Primary maternal infection is diagnosed with demonstration of seroconversion or a positive CMV IgM in combination with a low-avidity CMV IgG. Fetal infection may be diagnosed with amniotic fluid polymerase chain reaction and culture. CMV-specific hyperimmune globulin has shown promise as a possible means to prevent congenital infection; large randomized trials are ongoing. To date, the only effective means of prevention is through reducing exposure to the virus. Rates of maternal infection may be reduced through education regarding sources of infection and improved hygiene. Copyright © 2014 Elsevier Inc. All rights reserved.

    A compact ECR ion source has utilized for carbon radiotherapy. In order to increase beam intensity with higher electric field at the extraction electrode and be better ion supply stability for long periods, electric geometry and surface conditions of an extraction electrode have been studied. Focusing attention on black deposited substances on the extraction electrode, which were observed around the extraction electrode after long-term use, the relation between black deposited substances and the electrical insulation property is investigated. The black deposited substances were inspected for the thickness of deposit, surface roughness, structural arrangement examined using Raman spectroscopy, and characteristics of electric discharge in a test bench, which was set up to simulate the ECR ion source.

  15. Neutron source multiplication method

    International Nuclear Information System (INIS)

    Clayton, E.D.

    1985-01-01

    Extensive use has been made of neutron source multiplication in thousands of measurements of critical masses and configurations and in subcritical neutron-multiplication measurements in situ that provide data for criticality prevention and control in nuclear materials operations. There is continuing interest in developing reliable methods for monitoring the reactivity, or k/sub eff/, of plant operations, but the required measurements are difficult to carry out and interpret on the far subcritical configurations usually encountered. The relationship between neutron multiplication and reactivity is briefly discussed and data presented to illustrate problems associated with the absolute measurement of neutron multiplication and reactivity in subcritical systems. A number of curves of inverse multiplication have been selected from a variety of experiments showing variations observed in multiplication during the course of critical and subcritical experiments where different methods of reactivity addition were used, with different neutron source detector position locations. Concern is raised regarding the meaning and interpretation of k/sub eff/ as might be measured in a far subcritical system because of the modal effects and spectrum differences that exist between the subcritical and critical systems. Because of this, the calculation of k/sub eff/ identical with unity for the critical assembly, although necessary, may not be sufficient to assure safety margins in calculations pertaining to far subcritical systems. Further study is needed on the interpretation and meaning of k/sub eff/ in the far subcritical system

    Full Text Available Tacit knowledge definitions tend to be extremely varied. Some argue that tacit knowledge is precisely that. Others feel that only time and effort prevent all tacit knowledge from eventually becoming articulated. For the purposes of our research “tacit knowledge”, in practice at least, encompasses a medium ground, being comprised of articulable and inarticulable subsets. Along the lines of Weber (1997, we have formalised a meaning for this “tacit knowledge” and for comparison have completed a content analysis of the literature to determine what other researchers understand “tacit knowledge” to mean.

    Major investments by development partners in low- and middle-income countries (LMICs) often seek to develop a supportive policy environment. There is limited knowledge about the mechanisms that development partners use to influence government policy, or which mechanisms are effective. This study assessed the influence of Avahan, a large HIV/AIDS prevention program in India supported by the Bill and Melinda Gates Foundation, on the development of HIV/AIDS policies in India, particularly the National AIDS Control Program III (NACP III). A retrospective assessment of the contributions of Avahan to the development of NACP III was conducted based upon document review and in-depth interviews with key informants, including Avahan staff and staff of implementing partners. This assessment was carried out within a framework centered on three domains: evidence considered by policy and decision-makers; the channel through which influence is exerted; and the target audience for influence. Respondents identified a number of respects in which Avahan influenced NACP III policy, notably, Avahan influenced perception of the feasibility of scaling up services (through a demonstration effect) and Avahan, along with others, helped ensure a strong focus on targeted interventions. Overall Avahan's influence was greatest during policy implementation. While the extent to which research evidence generated by Avahan influenced NACP III was limited, best practice evidence generated by Avahan, including the lessons learned from routine implementation and management, contributed significantly to NACP III. This was largely due to the credibility Avahan had established and strategic 'inside track' communications. While studies of knowledge translation typically focus primarily on scientific evidence, this study suggests that other forms of evidence, notably best practice evidence derived from program experience, and disseminated through personal communication, were particularly influential.

    Background: An educational intervention on Sexually Transmitted Diseases (STDs accompanied by a multimedia exhibition was proposed in order to verify the effectiveness of an exhibition as a tool for prevention, to increase awareness in youth and to evaluate whether it yielded changes in the sexual behaviour of its’ visitors. The Target population were high schools and university students.

    Methods: The Exhibition consisted of a historical overview and four other sections: biological and clinical aspects, epidemiology, prevention and a section called the Red Zone with clear and explicit images relating to STDs. The exhibition was supported by three observational studies carried out on about2000 students of two High Schools and the university in the city of Cassino, Italy. Data collection took place through three different types of “ad hoc” questionnaires. The Statistical analysis carried out was that typical of cross-sectional surveys. We utilized the statistical program Epi-Info 3.5.

    Results: Regarding survey 1, 48% of 529 students taking part said that the exhibition had contributed “enough” for them to acquire new knowledge, 75.2% had already had sexual intercourse and 37.7% of them did not change their sexual habits. Relative to survey 2, 583 responded to the pre test and 403 posttests returned. Regarding knowledge, data obtained from processing of pre-tests showed how 63.9% of the sample did not know how many STDs existed, whilst this value dropped in post test answers to 49.2% . AIDS was the best known disease (96% whilst other STDs were little known. The educational intervention partly increased these percentages. With regard to sexual practices although 43% of the sample claimed to have already had sexual intercourse (66% male and 34% female. The family doctor is seen by a high percentage of young people (70% - 68.6% as the first figure which should address an

  1. Identifying advanced glycation end products as a major source of oxidants in aging: implications for the management and/or prevention of reduced renal function in elderly persons.

    Aging is characterized by increasing inflammation and oxidant stress (OS). Reduced renal function was present in more than 20% of normal-aged individuals sampled in the National Health and Nutrition Examination Survey (NHANES) cross-sectional study of the US population. Longitudinal studies in the United States and Italy showed that renal function does not decline in some individuals, suggesting that a search for causes of the loss of renal function in some persons might be indicated and interventions to reduce this outcome should be sought. Because advanced glycation end products (AGEs) induce both inflammation and OS, accumulate with age, and primarily are excreted by the kidney, one outcome of reduced renal function in aging could be decreased AGE disposal. The build-up of AGEs with reduced renal function could contribute to inflammation, increased oxidant stress, and accumulation of AGEs in aging. In fact, results from a longitudinal study of normal aging adults in Italy showed that the most significant correlation with mortality was the level of renal function. A clear link between inflammation, OS, AGEs, and chronic disease was shown in studies of mice that showed that reduction of AGE levels by drugs or decreased intake of AGEs reduces chronic kidney disease (CKD) and cardiovascular disease of aging. The data support a role for AGEs in the development of renal lesions in aging mice and reveal that AGEs in the diet are very important contributors to renal and cardiovascular lesions. AGEs signal through two receptors, one of which is anti-inflammatory (AGER1) and the other is proinflammatory (RAGE). Overexpression of AGER1 protects against OS and acute vascular injury. The reduction of AGEs in the diet is as efficient in preventing aging-related cardiovascular and renal lesions in mice as that seen with calorie restriction. Studies in normal adults of all ages and those with CKD suggest that the findings in mice may be directly applicable to both aging and CKD

    Restricting access to common means of suicide, such as firearms, toxic gas, pesticides and other, has been shown to be effective in reducing rates of death in suicide. In the present review we aimed to summarize the empirical and clinical literature on controlling the access to means of suicide. This review made use of both MEDLINE, ISI Web of Science and the Cochrane library databases, identifying all English articles with the keywords "suicide means", "suicide method", "suicide prediction" or "suicide prevention" and other relevant keywords. A number of factors may influence an individual's decision regarding method in a suicide act, but there is substantial support that easy access influences the choice of method. In many countries, restrictions of access to common means of suicide has lead to lower overall suicide rates, particularly regarding suicide by firearms in USA, detoxification of domestic and motor vehicle gas in England and other countries, toxic pesticides in rural areas, barriers at jumping sites and hanging, by introducing "safe rooms" in prisons and hospitals. Moreover, decline in prescription of barbiturates and tricyclic antidepressants (TCAs), as well as limitation of drugs pack size for paracetamol and salicylate has reduced suicides by overdose, while increased prescription of SSRIs seems to have lowered suicidal rates. Restriction to means of suicide may be particularly effective in contexts where the method is popular, highly lethal, widely available, and/or not easily substituted by other similar methods. However, since there is some risk of means substitution, restriction of access should be implemented in conjunction with other suicide prevention strategies.

    2017-01-01

    Full Text Available Suicide is a major public health problem in India, probably even bigger than in the West. Suicidal behavior is the best conceptualized as a multifaceted complex problem involving social factors and mental illnesses. Broadly, there are two approaches to suicide prevention; population preventive strategies and high-risk preventive strategies. Population preventive strategies include reducing availability of means for suicide, education of primary care physicians, influencing media portrayal of suicidal behavior, education of the public, telephone helplines, and addressing economic issues associated with suicidal behavior. High-risk preventive strategy includes identifying individuals with high risk of committing suicide, intensively treating mental illness if present, and providing psychosocial support. Thus, prevention requires a multipronged effort with collaboration from various sectors including mental health professionals, social justice department, and macroeconomic policy makers.

    The fuel cells transform the chemical energy stored in the connection H-H of the H{sub 2} molecule in electric energy and water vapor when is combines with the oxygen. Even when the hydrogen has a high potential as energy source, its handling is difficult (storage and transport). This has motivated the search of hydrogen production methods in situ starting from liquid fuels like the methanol or ethanol through the reaction of reforming. The methanol is a fuel of easy availability for fuel cells with electronic applications and of transport. Although the methanol energy density is approximately half of the gasoline and diesel, it is more reagent and can be used directly in fuel cells or can also be reformed to low temperatures for the hydrogen obtaining to be used in fuel cells of proton exchange. In this article the results obtained of the systems, Cu-Ni/ZrO{sub 2} and Ag-Au(1-D)-CeO{sub 2} are presented and can be competitive to generate H{sub 2} and being used in the fuel cells to generate energy.

  15. Implications for the crustal Architecture in West Antarctica revealed by the means of depth-to-the-bottom of the magnetic source (DBMS) mapping and 3D FEM geothermal heat flux models

    The West Antarctic Rift System (WARS) is one of the largest rift systems in the world, which displays unique coupled relationships between tectonic processes and ice sheet dynamics. Palaeo-ice streams have eroded troughs across the Amundsen Sea Embayment (ASE) that today route warm ocean deep water to the West Antarctic Ice Sheet (WAIS) grounding zone and reinforce dynamic ice sheet thinning. Rift basins, which cut across West Antarctica's landward-sloping shelves, promote ice sheet instability. Young, continental rift systems are regions with significantly elevated geothermal heat flux (GHF), because the transient thermal perturbation to the lithosphere caused by rifting requires 100 m.y. to reach long-term thermal equilibrium. The GHF in this region is, especially on small scales, poorly constrained and suspected to be heterogeneous as a reflection of the distribution of tectonic and volcanic activity along the complex branching geometry of the WARS, which reflects its multi-stage history and structural inheritance. We investigate the crustal architecture and the possible effects of rifting history from the WARS on the ASE ice sheet dynamics, by the use of depth-to-the-bottom of the magnetic source (DBMS) estimates. These are based on airborne-magnetic anomaly data and provide an additional insight into the deeper crustal properties. With the DBMS estimates we reveal spatial changes at the bottom of the igneous crust and the thickness of the magnetic layer, which can be further incorporated into tectonic interpretations. The DBMS also marks an important temperature transition zone of approximately 580°C and therefore serves as a boundary condition for our numerical FEM models in 2D and 3D. On balance, and by comparison to global values, we find average GHF of 90 mWm-2 with spatial variations due to crustal heterogeneities and volcanic activities. This estimate is 30% more than commonly used in ice sheet models in the ASE region.

    Determination of protein crystal structures requires that the phases are derived independently of the observed measurement of diffraction intensities. Many techniques have been developed to obtain phases, including heavy-atom substitution, molecular replacement and substitution during protein expression of the amino acid methionine with selenomethionine. Although the use of selenium-containing methionine has transformed the experimental determination of phases it is not always possible, either because the variant protein cannot be produced or does not crystallize. Phasing of structures by measuring the anomalous diffraction from S atoms could in theory be almost universal since almost all proteins contain methionine or cysteine. Indeed, many structures have been solved by the so-called native sulfur single-wavelength anomalous diffraction (S-SAD) phasing method. However, the anomalous effect is weak at the wavelengths where data are normally recorded (between 1 and 2 Å) and this limits the potential of this method to well diffracting crystals. Longer wavelengths increase the strength of the anomalous signal but at the cost of increasing air absorption and scatter, which degrade the precision of the anomalous measurement, consequently hindering phase determination. A new instrument, the long-wavelength beamline I23 at Diamond Light Source, was designed to work at significantly longer wavelengths compared with standard synchrotron beamlines in order to open up the native S-SAD method to projects of increasing complexity. Here, the first novel structure, that of the oxidase domain involved in the production of the natural product patellamide, solved on this beamline is reported using data collected to a resolution of 3.15 Å at a wavelength of 3.1 Å. The oxidase is an example of a protein that does not crystallize as the selenium variant and for which no suitable homology model for molecular replacement was available.

    Rushing, F.C.

    1960-09-01

    A description is given of sealing means between a hollow rotatable shaft and a stationary member surrounding the shaft which defines therewith a sealing space of annular cross-section, comprising a plurality of axially spaced rings held against seats by ring springs which serve to subdivide the sealing space- into a plurality of zones. Process gas introduced into the hollow shaft through a port communicating with a centrally located zone which iu turn communicates with a bore in the sleeve, is removed from the shaft through a second port communicating with an adjacent central zone and discharged through a second bore. A sealant gas is supplied to an end zone under a pressure sufficient to cause it to flow axially into adjacent zones and then maintained at a lower pressure than either the sealant gas source or the process gas inlet zone, preventing the sealant gas from entering the shaft and allowing gases leaking into the sealant gas to be withdrawn and led to a separator.

    Full Text Available This paper situates musical meaning in culture, addressing music as social symbol and as ongoing process of meaning creation. Three examples of non- Western musical practice are used to illustrate the embedding of musical meaning in cultural context. The performance of an Australian Aboriginal song is shown to exemplify the interdependence of song style and social structure as a matrix for the emergence of cultural meanings; an example of North Indian performance is adduced to demonstrate the multi-layered nature of meaning as embodied in musical performance; and an example of collective festival performance from Nepal illustrates ways in which the structure of musical performance can mirror local cultural forms. Each of the three examples lends weight to the idea that music's meanings are often non-linguistic and reflect foundational schemas that are specific to the cultures from the musics are drawn.

    Energy Technology Data Exchange (ETDEWEB)

    2017-04-04

    A parallelization of the k-means++ seed selection algorithm on three distinct hardware platforms: GPU, multicore CPU, and multithreaded architecture. K-means++ was developed by David Arthur and Sergei Vassilvitskii in 2007 as an extension of the k-means data clustering technique. These algorithms allow people to cluster multidimensional data, by attempting to minimize the mean distance of data points within a cluster. K-means++ improved upon traditional k-means by using a more intelligent approach to selecting the initial seeds for the clustering process. While k-means++ has become a popular alternative to traditional k-means clustering, little work has been done to parallelize this technique. We have developed original C++ code for parallelizing the algorithm on three unique hardware architectures: GPU using NVidia's CUDA/Thrust framework, multicore CPU using OpenMP, and the Cray XMT multithreaded architecture. By parallelizing the process for these platforms, we are able to perform k-means++ clustering much more quickly than it could be done before.

    This essay approaches Derrida through a consideration of his writings on Saussure and Husserl. Derrida is right to insist, following Saussure, on a relational theory on meaning: words do not have a one to one correspondence with their referents. However, he is wrong to insist on a purely differential theory of meaning: words can refer to reality within the context of a body of knowledge. Similarly, Derrida is right to reject Husserl's idea of presence: no truths are simply given to consciousn...

  20. Radiation induced cancer: risk assessment and prevention

    International Nuclear Information System (INIS)

    Shore, R.E.

    1984-01-01

    A number of factors have to be considered in defining the cancer risk from ionizing radiation. These include the radiation sensitivity of the target tissue(s), the temporal pattern of risk, the shape of the dose-incidence curve, the effects of low dose rates, host susceptibility factors, and synergism with other environmental exposures. For the population as a whole the largest sources of radiation exposure are natural background radiation and medical/dental radiation. Radiation exposures in the medical field make up the largest volume of occupational exposures as well. Although new technologies offer opportunities to lower exposures, worker training, careful exposure monitoring with remedial feedback, and monitoring to prevent unnecessary radiodiagnostic procedures may be even more important means of reducing radiation exposure. Screening of irradiated populations can serve a useful preventive function, but only for those who have received very high doses

  2. Evaluative Meaning in Translation

    Directory of Open Access Journals (Sweden)

    Primož Jurko

    2015-12-01

    Full Text Available Evaluative meaning is frequently understood as a form of connotation, pertaining to single lexical items. However, the term has recently been applied also to longer stretches of text, spanning several words. The paper generally deals with the latter aspect and provides a corpus-driven analysis of several Slovene and English phrases that may appear semantically neutral, yet turn out to be heavily non-neutral in terms of their semantic properties. After a short introduction of the main approaches to the topic, including its dilemmas, the paper focuses on the L1-into-L2 translation of such strings, with particular emphasis on proper rendering of the evaluative meaning. While further research is warranted into the matter, the work presented here attests to the complex and ubiquitous nature of the Sinclairian extended unit of meaning.

  17. Singular mean-filed games

    KAUST Repository

    Cirant, Marco

    2016-11-22

    Here, we prove the existence of smooth solutions for mean-field games with a singular mean-field coupling; that is, a coupling in the Hamilton-Jacobi equation of the form $g(m)=-m^{-\\\\alpha}$. We consider stationary and time-dependent settings. The function $g$ is monotone, but it is not bounded from below. With the exception of the logarithmic coupling, this is the first time that MFGs whose coupling is not bounded from below is examined in the literature. This coupling arises in models where agents have a strong preference for low-density regions. Paradoxically, this causes the agents to spread and prevents the creation of solutions with a very-low density. To prove the existence of solutions, we consider an approximate problem for which the existence of smooth solutions is known. Then, we prove new a priori bounds for the solutions that show that $\\\\frac 1 m$ is bounded. Finally, using a limiting argument, we obtain the existence of solutions. The proof in the stationary case relies on a blow-up argument and in the time-dependent case on new bounds for $m^{-1}$.

  19. Orphan sources in Slovenia

    International Nuclear Information System (INIS)

    Janzekovic, H.; Cesarek, J.

    2005-01-01

    For decades the international standards and requirements postulate severe control over all lifecycle phases of radioactive sources in order to prevent risks associated with exposure of people and the environment. Despite this fact the orphan sources became a serious problem as a consequence of enlargement of economic transactions in many countries in Europe as well as in the world. The countries as well as international organisations, aware of this emerging problem, are trying to gain control over orphan sources using different approaches. These approaches include control over sources before they could become orphan sources. In addition, countries are also developing action plans in case that an orphan source could be found. The problems related to orphan sources in Slovenia is discussed based on the case studies from the last years. While in the nineties of the last century just a few cases of orphan sources were identified their number has increased substantially since 2003. The paper discusses the general reasons for the phenomena of orphan sources as well as the experience related to regaining control over orphan sources. (author)

    WHO reports 36.7 million people are living with Human Immunodeficiency Virus (HIV) worldwide by 2016 with about 1.8 million new infections each year. It will be a specific health problem for the world in both developed and developing countries so it is necessary strategies to reduce HIV transmission to the community. HIV transmission in people with risk factors is largely determined by the amount of virus in the blood of people who are the source of infection. Antiretroviral (ARV) therapy has long been used in HIV patients, which serves to suppress viral replication so that the patient’s immunity increases; opportunistic infections are resolved and prolong the lifespan and lower transmission rates. In the HIV Prevention Trials Network (HPTN) study 052 there was a 96% reduction in transmission in earlier antiretroviral. ARV is also used in the prevention of transmission in people exposed to HIV virus that is Postexposure Prophylaxis as well as in people at risk before exposure (Pre-exposure Prophylaxis). Three prevention strategies with the provision of ARV is expected to be guided as a means of prevention of transmission in addition to behavioral changes has long been declared since the beginning of the HIV epidemic.

It is defended the importance to consider the complementarity of freedom of action and freedom of the will and it is argued for a non-metaphysical conception of adscription of freedom. The adequate use of the attribution of freedom is social and normative. This means additionally that the freedom is not a presupposition of the moral responsibility and the authorship, but on the contrary the moral responsibility and the authorship are presuppositions of the attribution of freedom.

  17. Mean gust shapes

    Energy Technology Data Exchange (ETDEWEB)

    Larsen, G.C.; Bierbooms, W.; Hansen, K.S.

    2003-12-01

    The gust events described in the IEC-standard are formulated as coherent gusts of an inherent deterministic character, whereas the gusts experienced in real situation are of a stochastic nature with a limited spatial extension. This conceptual difference may cause substantial differences in the load patterns of a wind turbine when a gust event is imposed. Methods exist to embed a gust of a prescribed appearance in a stochastic wind field. The present report deals with a method to derive realistic gust shapes based only on a few stochastic features of the relevant turbulence field. The investigation is limited to investigation of the longitudinal turbulence component, and consequently no attention is paid to wind direction gusts. A theoretical expression, based on level crossing statistics, is proposed for the description of a mean wind speed gust shape. The description also allows for information on the spatial structure of the wind speed gust and relies only on conventional wind field parameters. The theoretical expression is verified by comparison with simulated wind fields as well as with measured wind fields covering a broad range of mean wind speed situations and terrain conditions. The work reported makes part of the project 'Modelling of Extreme Gusts for Design Calculations' (NEWGUST), which is co-funded through JOULEIII on contract no. JOR3-CT98-0239. (au)

    Full Text Available This article presents and discusses a long-term repeated-immersion research process that explores meaning allocated to an episode of 50 seconds of music improvisation in early neurosurgical rehabilitation by a teenage boy with severe traumatic brain injury and his music therapist. The process began with the original therapy session in August 1994 and extends to the current time of writing in 2013. A diverse selection of qualitative research methods were used during a repeated immersion and engagement with the selected episodes. The multiple methods used in this enquiry include therapeutic narrative analysis and musicological and video analysis during my doctoral research between 2002 and 2004, arts-based research in 2008 using expressive writing, and arts-based research in 2012 based on the creation of a body cast of my right hand as I used it to play the first note of my music improvising in the original therapy episode, which is accompanied by reflective journaling. The casting of my hand was done to explore and reconsider the role of my own body as an embodied and integral, but originally hidden, part of the therapy process. Put together, these investigations explore the potential meanings of the episode of music improvisation in therapy in an innovative and imaginative way. However, this article does not aim at this stage to present a model or theory for neurorehabilitation but offers an example of how a combination of diverse qualitative methods over an extended period of time can be instrumental in gaining innovative and rich insights into initially hidden perspectives on health, well-being, and human relating.

    This article presents and discusses a long-term repeated-immersion research process that explores meaning allocated to an episode of 50 seconds of music improvisation in early neurosurgical rehabilitation by a teenage boy with severe traumatic brain injury and his music therapist. The process began with the original therapy session in August 1994 and extends to the current time of writing in 2013. A diverse selection of qualitative research methods were used during a repeated immersion and engagement with the selected episodes. The multiple methods used in this enquiry include therapeutic narrative analysis and musicological and video analysis during my doctoral research between 2002 and 2004, arts-based research in 2008 using expressive writing, and arts-based research in 2012 based on the creation of a body cast of my right hand as I used it to play the first note of my music improvising in the original therapy episode, which is accompanied by reflective journaling. The casting of my hand was done to explore and reconsider the role of my own body as an embodied and integral, but originally hidden, part of the therapy process. Put together, these investigations explore the potential meanings of the episode of music improvisation in therapy in an innovative and imaginative way. However, this article does not aim at this stage to present a model or theory for neurorehabilitation but offers an example of how a combination of diverse qualitative methods over an extended period of time can be instrumental in gaining innovative and rich insights into initially hidden perspectives on health, well-being, and human relating.

  4. On Meanings and Descriptions

    1981-09-01

    Full Text Available Although descriptive passages would appear to be of marginal importance in narrative texts, they are, in fact, of both logical and semantic necessity. Narratology, therefore, must take these segments into account. In this article, I shall survey the present situation in this field and compare rival points of view. I shall also offer several suggestions for analyzing descriptions. The following topics will be discussed: the nature of description as a specific type of discourse which makes it recognizable as such; the internal structure of description; the place and function of descriptions in the text as a whole. In the latter section, the semantic impact of descriptions in the overall meaning of narrative texts will be accounted for. This article is intended as a contribution to the theory of description as a part of narratology. It also has a didactic purpose, since it proposes a model for the analysis of texts which can be used for systematic text-study, both in a historical and a comparative perspective.

  5. The meaning of urbanism

    2009-06-01

    Full Text Available This article discusses an incomplete search on the different meanings understood from urbanism. It does so by discussing the relation of urbanism with urban planning and urban design. The similarities and differences between these concepts and the fact that they are often used indistinctly are pointed out. The current article is organized around two hypotheses, where the first involves a broader understanding of urbanism, which incorporates urban planning, and the second is based on the idea that the conceptual distinction between these two fields may be defined according to how close or how far urbanism is from art and architecture. The closer urbanism is to art and architecture, the more it moves away from urban planning. The ideas presented here are intended to be provocative, and the author is aware of reactions they may generate. This discussion is based on a technical literature as well as on debates with other researchers and students. The article starts with an introduction regarding the difficulties and complexities of an epistemological discussion while later sections point out similarities and distinctions between the two main concepts. The conclusion makes the author's position clear, but suggests that this issue needs further discussion.

  6. [Temporal meaning of suffering].

    Science.gov (United States)

    Porée, J

    2015-09-01

    If we had to find a few simple words to express what a suffering human being experiences, no matter what ills are causing the suffering and no matter what circumstances underlie the ills themselves, we could unmistakably say that it is the experience of not being able to go on like this. Suffering can be described, in this same sense, as an alteration in temporality. However, describing suffering as such only makes sense if we already have a conception of normal temporality. Yet for this, philosophical tradition offers not one but four competing conceptions. In the present article, we begin by briefly presenting these different conceptions. We then show how each one sheds light, by way of contrast, on a phenomenon whose meaning thus appears to be essentially negative. But does this phenomenon have a negative meaning only? Doesn't it correspond as much to a transformation as an alteration of temporality? This is what we will strive to establish in the third part of the article by relating suffering to hope, in a paradoxical sense of the term. Of the four conceptions of time likely to shed a contrasting light on the upheavals that suffering introduces into our life experience, the one described by Aristotle in Physics is historically the first. In particular, the notion of succession originates therein. But this conception does not account for what makes time the unit of a past, a present, and a future. In Book XI of Confessions, St. Augustine situated this unit not in nature but in the human mind. Hence, his definition of time as a distension of the soul and the necessary division into physical time and psychic time it entails. Husserl's Lessons on the phenomenology of the consciousness of internal time lend credit to this division, but they illuminate only the internal constitution of the "present", which is at the heart of the psychological conception of time. In Being and Time, Heidegger breaks away from this long-standing tradition; in his view, physical time

  12. The Meaning of "Magma"

    Science.gov (United States)

    Bartley, J. M.; Glazner, A. F.; Coleman, D. S.

    2016-12-01

    Magma is a fundamental constituent of the Earth, and its properties, origin, evolution, and significance bear on issues ranging from volcanic hazards to planetary evolution. Unfortunately, published usages indicate that the term "magma" means distinctly different things to different people and this can lead to miscommunication among Earth scientists and between scientists and the public. Erupting lava clearly is magma; the question is whether partially molten rock imaged at depth and too crystal-rich to flow should also be called magma. At crystal fractions > 50%, flow can only occur via crystal deformation and solution-reprecipitation. As the solid fraction increases to 90% or more, the material becomes a welded crystal framework with melt in dispersed pores and/or along grain boundaries. Seismic images commonly describe such volumes of a few % melt as magma, yet the rheological differences between melt-rich and melt-poor materials make it vital not to confuse a large rock volume that contains a small melt fraction with melt-rich material. To ensure this, we suggest that "magma" be reserved for melt-rich materials that undergo bulk fluid flow on timescales consonant with volcanic eruptions. Other terms should be used for more crystal-rich and largely immobile partially molten rock (e.g., "crystal mush," "rigid sponge"). The distinction is imprecise but useful. For the press, the public, and even earth scientists who do not study magmatic systems, "magma" conjures up flowing lava; reports of a large "magma" body that contains a few percent melt can engender the mistaken perception of a vast amount of eruptible magma. For researchers, physical processes like crystal settling are commonly invoked to account for features in plutonic rocks, but many such processes are only possible in melt-rich materials.

  13. Schizophrenia: two-faced meaning of vulnerability.

    Science.gov (United States)

    Azorin, Jean-Michel; Naudin, Jean

    2002-12-08

    The authors stress the current two-faced meaning of vulnerability that conveys both an objective and a subjective direction of sense, leading to a naturalistic model as well as a humanistic one. These models are heirs of both the Kraepelinian and Bleulerian conceptions of schizophrenia. Coping strategies and resilience are core concepts of the humanistic model. Research on these protective factors may be of major importance in the current debate on prevention in schizophrenia. Copyright 2002 Wiley-Liss, Inc.

    The technology for Gd-153 line source production has been developed at SSC RIAR. The source active core is made of Al-Gd{sub 2}O{sub 3} composition by means of one of the following ways: either collecting pressed pellets or filling the source body with the composition followed by sintering. The composition is prepared by gadolinium salt thermal destruction on aluminium particles. The method allows setting gadolinium mass fraction (from 0.02 to 6%) with high accuracy and uniformity of distribution in the composition volume of more than 95%.

    A light source is provided by a photonic crystal having an enhanced photonic density-of-states over a band of frequencies and wherein at least one of the dielectric materials of the photonic crystal has a complex dielectric constant, thereby producing enhanced light emission at the band of frequencies when the photonic crystal is heated. The dielectric material can be a metal, such as tungsten. The spectral properties of the light source can be easily tuned by modification of the photonic crystal structure and materials. The photonic crystal light source can be heated electrically or other heating means. The light source can further include additional photonic crystals that exhibit enhanced light emission at a different band of frequencies to provide for color mixing. The photonic crystal light source may have applications in optical telecommunications, information displays, energy conversion, sensors, and other optical applications.

    2014-11-01

    Inhalation of carbon monoxide (CO) can result in poisoning, with symptoms ranging from mild and nonspecific to severe, or even death. CO poisoning is often underdiagnosed because exposure to low concentrations goes unnoticed, and threshold values for normal carboxyhemoglobin vary according to different authors. The aim of our study was to analyze carboxyhemoglobin (COHb) levels in an unselected population and detect sources of CO exposure In a cross-sectional descriptive study, we analyzed consecutive arterial blood gas levels processed in our laboratory. We selected those with COHb≥2.5% in nonsmokers and ≥5% in smokers. In these cases a structured telephone interview was conducted. Elevated levels of COHb were found in 64 (20%) of 306 initial determinations. Of these, data from 51 subjects aged 65±12 years, 31 (60%) of which were men, were obtained. Mean COHb was 4.0%. Forty patients (78%) were non-smokers with mean COHb of 3.2%, and 11 were smokers with COHb of 6.7%. In 45 patients (88.2%) we detected exposure to at least one source of ambient CO other than cigarette smoke. A significant proportion of individuals from an unselected sample had elevated levels of COHb. The main sources of CO exposure were probably the home, so this possibility should be explored. The population should be warned about the risks and encouraged to take preventive measures. Copyright © 2013 SEPAR. Published by Elsevier Espana. All rights reserved.

    To identify sources of general and mental health information for rural women to inform the development of public health nursing interventions that consider preferences for obtaining information. One thousand women (mean age = 57 years; 96.9% White) living in primarily nonmetropolitan areas of Western Kentucky participated via a random-digit-dial survey. Data were collected on demographics, sources of health information, depression, and stigma. Most participants preferred anonymous versus interpersonal sources for both general (68.1%) and mental health (69.4%) information. All participants reported at least one source of general health information, but 20.8% indicated not seeking or not knowing where to seek mental health information. The Internet was the most preferred anonymous source. Few women cited health professionals as the primary information source for general (11.4%) or mental (9.9%) health. Public stigma was associated with preferring anonymous sources and not seeking information. Public health nurses should understand the high utilization of anonymous sources, particularly for mental health information, and focus efforts on helping individuals to navigate resources to ensure they obtain accurate information about symptoms, effective treatments, and obtaining care. Reducing stigma should remain a central focus of prevention and education in rural areas. © 2014 Wiley Periodicals, Inc.

  2. Synchrotron sources

    Energy Technology Data Exchange (ETDEWEB)

    Hulbert, S.L.

    1999-12-13

    Synchrotron radiation is a very bright, broadband, polarized, pulsed source of electromagnetic radiation extending from the infrared to the x-ray region. Brightness, defined as flux per unit area per unit solid angle, is normally a more important quantity than flux or intensity, particularly in throughput limited applications which include those in which monochromators are used. The authors have attempted to compile the formulae needed to calculate the flux, brightness, polarization and power produced by the three standard storage ring synchrotron radiation sources: bending magnets, wigglers and undulators. Where necessary, these formulae have contained reference to the emittance of the electron beam, as well as to the electron beam size and its divergence. For all three type sources, the source phase space area, i.e. the spatial and angular extent of the effective (real) source, is a convolution of its electron and photon components.

  3. Pollution prevention: A regulatory update

    International Nuclear Information System (INIS)

    Walzer, A.E.; Maynard, J.W.

    1993-01-01

    Pollution prevention is the emphasis of the 1990s environmental philosophy. This new environmental era was ushered in when President Bush signed the Pollution Prevention Act in October 1990. This law, with its accompanying philosophy, was in response to the realization that end-of-the-pipe treatment, which frequently changed the media in which a pollutant or waste was discharged, was inadequate to protect the environment and human health. Pollution prevention advocates source reduction, where material substitutions and engineering solutions are sought to reduce the volume and toxicity of waste and pollutants. This proactive approach reduces environmental impacts such as those of former waste sites which have produced environmental legacies that will cost billions of dollars and take decades to remediate. This paper describes pollution prevention philosophy and summarizes regulatory pollution prevention requirements. It describes current regulatory trends in the area of pollution prevention, including voluntary programs and enforcement actions. The Pollution Prevention Act of 1990 is described, and pollution prevention initiatives embodied in other laws, including the Clean Air Act, the Clean Water Act, the Emergency Planning and Community Right-To-Know Act, the Resource Conservation and Recovery Act, and the Toxic Substances Control Act, are discussed. A historical overview of waste minimization initiatives within the Department of Energy is given, and other pollution prevention initiatives that affect federal facilities, such as Executive Order 12780, which mandates recycling and the procurement of recycled materials, are also outlined

    The further increase of allergies in industrialized countries demands evidence-based measures of primary prevention. The recommendations as published in the guideline of 2004 were updated and consented on the basis of a systematic literature search. Evidence from the period February 2003-May 2008 was searched in the electronic databases Cochrane and MEDLINE as well as in reference lists of recent reviews and by contacting experts. The retrieved citations were screened for relevance first by title and abstract and in a second step as full paper. Levels of evidence were assigned to each included study and the methodological quality of the studies was assessed as high or low. Finally the revised recommendations were formally consented (nominal group process) by representatives of relevant societies and organizations including a self-help group. Of originally 4556 hits, 217 studies (4 Cochrane Reviews, 14 meta-analyses, 19 randomized controlled trials, 135 cohort and 45 case-control studies) were included and critically appraised. Grossly unchanged remained the recommendations on avoiding environmental tobacco smoke, breast-feeding over 4 months (alternatively hypoallergenic formulas for children at risk), avoiding a mold-promoting indoor climate, vaccination according to current recommendations, and avoidance of furry pets (especially cats) in children at risk. The recommendation on reducing the house dust mite allergen exposure as a measure of primary prevention was omitted and the impact of a delayed introduction of supplementary food was reduced. New recommendations were adopted concerning fish consumption (during pregnancy / breast-feeding and as supplementary food in the first year), avoidance of overweight, and reducing the exposure to indoor and outdoor air pollutants. The revision of this guideline on a profound evidence basis led to (1) a confirmation of existing recommendations, (2) substantial revisions, and (3) new recommendations. Thereby it is possible

    2015-01-01

    Human and animal influenza are inextricably linked. In particular, the pig is uniquely important as a mixing vessel for genetic reassortment of influenza viruses, leading to emergence of novel strains which may cause human pandemics. Significant reduction in transmission of influenza viruses from humans, and other animals, to swine may therefore be crucial for preventing future influenza pandemics. This study investigated the presence of the 2009 pandemic influenza A/H1N1 virus, A(H1N1)pdm09, in Nigerian and Ghanaian pigs, and also determined levels of acceptance of preventive measures which could significantly reduce the transmission of this virus from humans to pigs. Nasal swab specimens from 125 pigs in Ibadan, Nigeria, and Kumasi, Ghana, were tested for the presence of influenza A/California/04/2009 (H1N1) by quantitative antigen-detection ELISA. A semi-structured questionnaire was also administered to pig handlers in the two study areas and responses were analyzed to evaluate their compliance with seven measures for preventing human-to-swine transmission of influenza viruses. The virus was detected among pigs in the two cities, with prevalence of 8% in Ibadan and 10% in Kumasi. Levels of compliance of pig handlers with relevant preventive measures were also found to be mostly below 25 and 40% in Ibadan and Kumasi, respectively. Detection of influenza A(H1N1)pdm09 among pigs tested suggests the possibility of human-to-swine transmission, which may proceed even more rapidly, considering the very poor acceptance of basic preventive measures observed in this study. This is also the first report on detection of influenza A(H1N1)pdm09 in Ghanaian pigs. We recommend improvement on personal hygiene among pig handlers, enforcement of sick leave particularly during the first few days of influenza-like illnesses, and training of pig handlers on recognition of influenza-like signs in humans and pigs. These could be crucial for prevention of future influenza pandemics.

    In a negative ion source having magnetic filters, bisecting magnetic fields are formed using electromagnets disposed at the outside of a plasma source. The position of the electromagnets is made adjustable and removable to optimize a negative ion generation efficiency. Further, a plurality of electromagnets are disposed in longitudinal direction of the plasma source, and the intensity of the magnetic fields of the filters in the longitudinal direction is made adjustable to control a beam distribution. Since uniform magnetic fields which bisect the plasma source can be formed by the electromagnets, and magnetomotive force of the electromagnets can be increased easily compared with that of permanent magnets, the magnetomotive force is changed to obtain appropriate filter magnetic fields easily. Then, optimum magnetic fields corresponding to the state of source plasmas can be generated by the control of the power source of the electromagnets, which also increases the negative ion drawing current density, thereby enabling to reduce the drawing area and size of the plasma source.

    The gamma rays are produced during the disintegration of the atomic nuclei, its high energy allows them to cross thick materials. The capacity to attenuate a photons beam allows to determine the density, in line, of industrial interest materials as the mining. By means of two active dosemeters and a TLDs group (passive dosimetry) the dose rates of two sources of Cs-137 used for determining in line the density of mining materials were determined. With the dosemeters the dose levels in diverse points inside the grave that it harbors the sources and by means of calculations the isodoses curves were determined. In the phase of calculations was supposed that both sources were punctual and the isodose curves were calculated for two situations: naked sources and in their Pb packings. The dosimetry was carried out around two sources of 137 Cs. The measured values allowed to develop a calculation procedure to obtain the isodoses curves in the grave where the sources are installed.

    The establishment of a project to analyse the nature and extent of the problem of marine oil spills and their impact on the wildlife in coastal Newfoundland was described. Pelagic seabirds were identified as the marine wildlife most affected by oil released into the ocean. The Prevention of Oiled Wildlife (POW) project was initiated by the Canadian Coast Guard, the lead agency for oil spills of unknown origin. Details of the POW project were provided. It was shown that the project serves as an interdepartmental approach to: (1) identifying past occurrences, probable sources, causes, effects and possible releases of oil into the marine environment, (2) identifying remedial measures undertaken to date to curb the release of oil, and (3) establishing a plan of action through legislation, education, detection, prosecution or any other means, to eliminate the release of oil. 14 refs., 4 tabs., 5 figs

    This paper reports that recent changes in the oil and gas industry and ongoing developments in horizontal and underbalanced drilling necessitated development of a better rotating head. A new device called the rotating blowout preventer (RBOP) was developed by Seal-Tech. It is designed to replace the conventional rotating control head on top of BOP stacks and allows drilling operations to continue even on live (underbalanced) wells. Its low wear characteristics and high working pressure (1,500 psi) allow drilling rig crews to drill safely in slightly underbalanced conditions or handle severe well control problems during the time required to actuate other BOPs in the stack. Drilling with a RBOP allows wellbores to be completely closed in tat the drill floor rather than open as with conventional BOPs

    Full Text Available The study investigates the required skills and ethics of the forensic accountant in preventing fraudulent practices in the Nigerian public sector. The primary source of data was utilized for data collection. Using the simple random sampling (SRS, a total of 300 questionnaires were administered; 163 were retrieved. The data obtained was analyzed using SmartPLS - for measurement and structural model. One of the major findings revealed that skills requirement was significant predator of fraud prevention as well as ethics requirement. This means that the higher the skills and ethics of the forensic accountant, the better is the fraud prevention. It is thus, recommended that forensic accounting services should be made statutory in the Nigerian public sector to help in preventing fraudulent practices. Hence the need to create awareness and expand the application of forensic accounting services in Nigerian public sector.

    Hall, S M; Wasserman, D A; Havassy, B E

    1991-01-01

    Although knowledge about relapse prevention is still at an early stage, the extant data highlight the importance of several constructs. 1. Motivation for abstinence remains central. The construct itself is often clouded because of its association with mystical notions such as willpower and self-control. We know that manipulation of environmental events can increase motivation. These interventions are effective, however, only as long as the contingencies are in effect. We need to develop and evaluate strategies for transferring contingency management to the natural environment, that is, to institutions and groups that can perpetuate them for the long term. Also, clarification of the kinds of abstinence goals needed to prevent relapse is important. 2. Coping skills have been studied by several investigators, but research on these, except for job-finding skills, is not encouraging. The skills usually taught may be too basic. Skills training oriented to complex targets, such as building nondrug-using networks, may be useful and should be further explored. 3. Social support is clearly important, yet we do not know how best to use it to promote abstinence. The little research available suggests that both familial and nonfamilial systems should be mobilized. We need to define abstinence-promoting supportive behaviors, identify and engage important support systems in treatment, and help patients expand their nondrug-using contacts. 4. Negative affect may be causally related to relapse. We need to continue efforts to identify dysphoric patients and develop interventions to ameliorate dysphoria concurrent with drug abuse treatment (cf. Zweben and Smith 1989). 5. Drug cue reactivity and extinction to drug cues have been demonstrated in the laboratory. What is needed in this promising line of research are (1) investigation of cues and cue-reactivity phenomena in the natural environment or in conditions closely mimicking that environment and (2) extinction methods that transfer

  12. What Do We Mean by the Meanings of Music?

    Directory of Open Access Journals (Sweden)

    Philip J. Barnard

    2012-09-01

    Full Text Available Drawing upon a recent review of the topic by Cross and Tolbert (2009, this paper briefly illustrates the diversity of theories concerning the nature of meanings in music and the challenges that need to be resolved to advance the field. A scheme for layered macro- and micro-theories for neural, mental and behavioural systems is outlined to facilitate the development of a systematic and coherent body of theory. The core of the paper charts the evolutionary origins of a specific macro- theory of the organisation all the components of the human mind. This “mental architecture,” known as Interacting Cognitive Subsystems (Barnard, 1985, incorporates not one, but two qualitatively distinct forms of meaning. Propositional meanings represent referentially specific ideas while implicational meanings encapsulate a yet more abstract and holistic form of meaning that blends conceptual material with the products of immediate distal and bodily sensations. While both forms of meaning interact in the interpretation and expression of musical meaning, such meanings are argued to be primarily implicational in nature. The paper concludes with a short discussion of how this approach might usefully be applied in the development of more precise specification of what music might mean in its various facets.

    Advanced source control (once-daily bathing and 4-times daily oral care with chlorhexidine aqueous solution) and thorough environmental cleaning were implemented in response to an increased incidence of colonization and infection with extremely drug-resistant (XDR) Acinetobacter baumannii in a Thai medical intensive care unit (MICU). During the 12-month baseline period (P1), contact isolation, active surveillance for XDR A baumannii, cohorting of XDR A baumannii patients, twice-daily environmental cleaning with detergent-disinfectant, and antibiotic stewardship were implemented. In the 5.5-month intervention period (P2), additional measures were introduced. Sodium hypochlorite was substituted for detergent-disinfectant, and advanced source control was implemented. All interventions except cleaning with sodium hypochlorite were continued during the 12.5-month follow-up period (P3). Extensive flooding necessitating closure of the hospital for 2 months occurred between P2 and P3. A total of 1,365 patients were studied. Compared with P1 (11.1 cases/1,000 patient-days), the rate of XDR A baumannii clinical isolates declined in P2 (1.74 cases/1,000 patient-days; P control and thorough environmental cleaning to limit colonization and infection with XDR A baumannii in MICUs in resource-limited settings.

  20. Adjective metaphors evoke negative meanings.

    Directory of Open Access Journals (Sweden)

    Maki Sakamoto

    Full Text Available Previous metaphor studies have paid much attention to nominal metaphors and predicative metaphors, but little attention has been given to adjective metaphors. Although some studies have focused on adjective metaphors, they only examined differences in the acceptability of various types of adjective metaphors. This paper explores the cognitive effects evoked by adjective metaphors. Three psychological experiments revealed that (1 adjective metaphors, especially those modified by color adjectives, tend to evoke negative effect; (2 although the meanings of metaphors are basically affected by the meanings of their vehicles, when a vehicle has a neutral meaning, negative meanings are evoked most frequently for adjective metaphors compared to nominal and predicative metaphors; (3 negative meanings evoked by adjective metaphors are related to poeticness, and poetic metaphors evoke negative meanings more easily than less poetic metaphors. Our research sheds new light on studies of the use of metaphor, which is one of the most basic human cognitive abilities.

    Full Text Available We raise several elementary questions pertaining to various aspects of means. These questions refer to both known and newly introduced families of means, and include questions of characterizations of certain families, relations among certain families, comparability among the members of certain families, and concordance of certain sequences of means. They also include questions about internality tests for certain mean-looking functions and about certain triangle centers viewed as means of the vertices. The questions are accessible to people with no background in means, and it is also expected that these people can seriously investigate, and contribute to the solutions of, these problems. The solutions are expected to require no more than simple tools from analysis, algebra, functional equations, and geometry.

  2. Joke as a means of conflict settling

    Directory of Open Access Journals (Sweden)

    Yana A. Sadovnikova

    2016-09-01

    Full Text Available The article is devoted to the use of jokes as one of the verbal means of deintensification of confrontation. The examples from modern English works of art illustrating the use of jokes at different stages of the conflict are presented. As a rule, a joke can be used in open and post-conflict phases, the latent phase of the conflict is not expressed. The use of jokes on the open stage of the conflict can create a kind of tipping point to change the course of the conflict, and thereby help to resolve it. On the post-conflict stage, a joke helps to build relationships that can be important preventing renewed conflict. The article draws attention to the combination of other means of deintensification confrontation with a joke to achieve the best result in the conflict settlement process. The verbal means can be referred to the apology and change of subject, non-verbal gestures and kisses, para-verbal — soothing tone. All of these funds, if used in conjunction with a joke, contribute to a successful resolution of the conflict. They can also enhance the effect of the joke, which is especially important in the case of non-verbal means. The author notes that the effectiveness of the joke depends on both sides — how well one of the interviewees apply the tool and how the second would take it. In the case of a failed joke, the conflict is likely to increase.

  3. Subspace K-means clustering.

    2013-12-01

    To achieve an insightful clustering of multivariate data, we propose subspace K-means. Its central idea is to model the centroids and cluster residuals in reduced spaces, which allows for dealing with a wide range of cluster types and yields rich interpretations of the clusters. We review the existing related clustering methods, including deterministic, stochastic, and unsupervised learning approaches. To evaluate subspace K-means, we performed a comparative simulation study, in which we manipulated the overlap of subspaces, the between-cluster variance, and the error variance. The study shows that the subspace K-means algorithm is sensitive to local minima but that the problem can be reasonably dealt with by using partitions of various cluster procedures as a starting point for the algorithm. Subspace K-means performs very well in recovering the true clustering across all conditions considered and appears to be superior to its competitor methods: K-means, reduced K-means, factorial K-means, mixtures of factor analyzers (MFA), and MCLUST. The best competitor method, MFA, showed a performance similar to that of subspace K-means in easy conditions but deteriorated in more difficult ones. Using data from a study on parental behavior, we show that subspace K-means analysis provides a rich insight into the cluster characteristics, in terms of both the relative positions of the clusters (via the centroids) and the shape of the clusters (via the within-cluster residuals).

    Full Text Available West Beni Suef Concession is located at the western part of Beni Suef Basin which is a relatively under-explored basin and lies about 150 km south of Cairo. The major goal of this study is to evaluate the source rock by using different techniques as Rock-Eval pyrolysis, Vitrinite reflectance (%Ro, and well log data of some Cretaceous sequences including Abu Roash (E, F and G members, Kharita and Betty formations. The BasinMod 1D program is used in this study to construct the burial history and calculate the levels of thermal maturity of the Fayoum-1X well based on calibration of measured %Ro and Tmax against calculated %Ro model. The calculated Total Organic Carbon (TOC content from well log data compared with the measured TOC from the Rock-Eval pyrolysis in Fayoum-1X well is shown to match against the shale source rock but gives high values against the limestone source rock. For that, a new model is derived from well log data to calculate accurately the TOC content against the limestone source rock in the study area. The organic matter existing in Abu Roash (F member is fair to excellent and capable of generating a significant amount of hydrocarbons (oil prone produced from (mixed type I/II kerogen. The generation potential of kerogen in Abu Roash (E and G members and Betty formations is ranging from poor to fair, and generating hydrocarbons of oil and gas prone (mixed type II/III kerogen. Eventually, kerogen (type III of Kharita Formation has poor to very good generation potential and mainly produces gas. Thermal maturation of the measured %Ro, calculated %Ro model, Tmax and Production index (PI indicates that Abu Roash (F member exciting in the onset of oil generation, whereas Abu Roash (E and G members, Kharita and Betty formations entered the peak of oil generation.

    Tritium is the only radioactive isotope of hydrogen. It directly follows the metabolism of water and it can be bound into genetic material, so it is very important to control levels of contamination. In order to define the state of contamination it is necessary to establish 'zero level', i.e. actual global inventory. The importance of tritium contamination monitoring increases with the development of fusion power installations. Different sources of tritium are analyzed and summarized in this paper. (author)

    and secured in the end by safeguards, and that the problematic of nuclear ambivalence could not be seriously tackled. Therefore, in this investigation, we think beyond safeguards and try to find out more advanced ways of preventive arms control and of the concept of proliferation resistance. At an early stage and with a preventive perspective appropriate measures have to be developed and to be implemented, which serve the aim of nuclear non-proliferation (i.e. no further spread and disarmament) most effectively. In particular, we discuss three approaches using technological examples as part of a concept of preventive nuclear arms control: the disposal of nuclear weapon materials, the anticipation of technology-driven proliferation risks, and the improvement of proliferation resistance. The disposal approach has an immense impact on the efforts to make nuclear disarmament irreversible. Without the disposal of nuclear weapon-relevant materials which at least has to ensure that it is converted to a more proliferation resistant form, nuclear disarmament remains incomplete and unconvincing. That necessity exists also in states, which in principle possess a weapon-capability due to the access to sufficient and suitable amounts of nuclear weapon-relevant materials. A systematic effort to anticipate predictable dangers by nuclear technologies is much more necessary then ever, today, due to the ongoing scientific-technological dynamic. If new dangerous potentials are discovered early in the development process, there is a chance to have an impact on the technological development itself. In consequence, this leads to the concept of proliferation resistance. By introducing proliferation resistance, intrinsic technical possibilities for shaping nuclear technologies and facilities or for the physical conversion of weapon materials are used in order to ensure a barrier as high as possible against an imaginable military use. The research project is focusing on two highly relevant

    A full high energy muon collider may take considerable time to realize. However, intermediate steps in its direction are possible and could help facilitate the process. Employing an intense muon source to carry out forefront low energy research, such as the search for muon-number non-conservation, represents one interesting possibility. For example, the MECO proposal at BNL aims for 2 x 10 -17 sensitivity in their search for coherent muon-electron conversion in the field of a nucleus. To reach that goal requires the production, capture and stopping of muons at an unprecedented 10 11 μ/sec. If successful, such an effort would significantly advance the state of muon technology. More ambitious ideas for utilizing high intensity muon sources are also being explored. Building a muon storage ring for the purpose of providing intense high energy neutrino beams is particularly exciting.We present an overview of muon sources and example of a muon storage ring based Neutrino Factory at BNL with various detector location possibilities

    Asbridge, Mark; Smart, Reginald G; Mann, Robert E

    2006-04-01

    Road rage has become a serious concern in many countries, and preventive efforts are required. This article reviews what can be done to prevent road rage by exploring potential prevention avenues in five areas. First, legal changes aimed at increasing the penalties for road rage behavior could be instituted, drawing on models from aggressive-driving or impaired-driving laws. A second approach would involve the adoption of court programs for convicted road ragers. Third, car redesign offers a means of reducing crime through environmental design. Fourth, mass media education could be implemented to inform drivers of the risk from road rage and how to avoid situations that facilitate road rage. Finally, prevention efforts could be directed to long-term societal changes that emphasize structural modifications, such as reducing congestion on the roads, reduced driver stress, or promoting public transportation. The strengths and weaknesses of these strategies are discussed.

When the situation was detected by means removal contamination tests, after routine inspections, the sources were removed from the hospitals, decontaminated by means of immersion in 3% EDTA solution in ultrasonic bath, subjected to leaking assessment tests, and the ones that passed were placed in low cost stainless steel source holders, designed and built by the instituto Venezolano de Investigaciones Cientificas (IVIC) returned to the hospitals. The leaking sources were removed from use and considered radioactive waste. In order to avoid the occurrence of similar situations, all the importers of such sources are now required to send them to IVIC for testing and placement in proper source holders, before they are shipped to the hospitals.

    2011-04-01

    Full Text Available This study examined how different patterns of sources of meaning in life impact the psychosocial adaptation of older adults. A total of 120 (62 women and 58 men community-residing older adults completed self-report measures of sources of meaning in life, physical health, life satisfaction, depression, personality, existential regrets, attitudes toward aging, and attitudes toward life. Cluster analysis of sources of meaning revealed four distinct meaning orientations: self-transcendent (n = 32, collectivistic (n = 24, individualistic (n = 34, and self-preoccupied (n = 30. MANCOVA analysis of the four groups, controlling for age, marital status, education, and financial satisfaction, revealed a strong multivariate main effect for meaning orientation. No statistically significant gender and Gender × Meaning orientation interaction effects were found. Older adults, who derive meaning from self-transcendent sources, are more extraverted, open to experience, agreeable, and conscientious; perceive greater purpose and coherence in life; feel more in control in directing their lives; express a stronger desire to get more out of life; and are less depressed compared with those who derive meaning through pursuing self-serving interests without any real commitment to personal, interpersonal, or societal development. The implications of the findings for positive aging are discussed.

    2016-10-01

    Full Text Available This study aims at making considerations about what homes mean to their residents, an an approach related to the socio-cultural processes underlying its spatiality. The article is essentially theoretical and based on the literature. Following this methodology, the research was conducted in order to explore ethnographic sources focused on the anthropology of space. Reflections were guided by the notion of homes as well as the relations established in them, with emphasis on the intersection between the territorial, architectural, cultural, sociodemographic and psychological aspects. In addition to conceptual abstractions, the investigation aims to understand the meaning of and in space, the importance of homes, and the relationships established between them and their residents.

  18. Lectures on mean curvature flows

    CERN Document Server

    Zhu, Xi-Ping

    2002-01-01

    "Mean curvature flow" is a term that is used to describe the evolution of a hypersurface whose normal velocity is given by the mean curvature. In the simplest case of a convex closed curve on the plane, the properties of the mean curvature flow are described by Gage-Hamilton's theorem. This theorem states that under the mean curvature flow, the curve collapses to a point, and if the flow is diluted so that the enclosed area equals \\pi, the curve tends to the unit circle. In this book, the author gives a comprehensive account of fundamental results on singularities and the asymptotic behavior of mean curvature flows in higher dimensions. Among other topics, he considers in detail Huisken's theorem (a generalization of Gage-Hamilton's theorem to higher dimension), evolution of non-convex curves and hypersurfaces, and the classification of singularities of the mean curvature flow. Because of the importance of the mean curvature flow and its numerous applications in differential geometry and partial differential ...

  20. Pollution prevention opportunity assessment: Foundation of pollution prevention for waste management

    International Nuclear Information System (INIS)

    Damewood, R.W.

    1994-01-01

    The objective of this paper is to promote the Pollution Prevention Opportunity Assessment (PPOA) technique as a fundamental of pollution prevention for waste management. All key elements of an effective PPOA program are presented. These key elements include impacts of environmental laws on pollution prevention, PPOA concepts and overview, waste minimization opportunities assessment, reporting and monitoring waste minimization progress, and PPOA program implementation. As environmental laws evolve the focus is shifting from end-of-pipe pollution control to front-end source reduction. Waste minimization was mistakenly interpreted to mean the reduction of hazardous waste after generation in the past. The Pollution Prevention Act of 1990 has clearly defined its requirement on resource reduction. Waste reduction can be viewed as a criterion to assess all industrial processes and operations. The fundamental approach of PPOA focuses on a mass balance concept. This concept deals with tracking of chemicals from the point of purchase, through storage, utilization in the process, and waste generation at the end of process. In other words, PPOA is a technique to analyze this input/output process. By applying PPOA techniques, the framework of applicable compliance requirements to the current operation process is established. Furthermore, documentation of PPOA itself can meet as documentation requirements for environmental compliance. In general, the PPOA process consists of two phases. The first phase involves input and output process description and waste characterization. The second phase is an opportunities assessment for waste minimization from input/output waste characterization. These two phases are explained in detail in the paper

Statistical analysis: Descriptive (mean and percentage), comparative Chi square Test (significance level Pmama and cervix. 20% (CI 0,13-0,28) knew that colon cancer has a genetic predisposition and 58% (CI 0,48-0,67) about mama. 73% (CI 0,63-0,8) received information about cancer prevention. The main source of information was the physician. 46% (CI 0,36-0,55) received medical care in private institutions. Those who had social security, higher educational levels and medical care in private institutions had better knowledge about cancer prevention except in colon cancer. The global results showed levels below 70% in general but extremely low in colon cancer. Not having social security, receiving medical care in public institutions and having a low educational level are related with poor knowledge about cancer prevention except for colon and prostate cancer.

  12. Radiation Safety and Orphan Sources

    International Nuclear Information System (INIS)

    Janzekovic, H.; Krizman, M.

    2006-01-01

    The wide spread use of radioactive and particularly of nuclear materials which started in the last century very quickly also demonstrated negative sides. The external exposure and radiotoxicity of these materials could be easily used in a malevolent act. Due to the fact that these materials could not be detected without special equipment designed for that purpose, severe control over their use in all phases of a life cycle is required. An orphan source is a radioactive source which is not under regulatory control, either because it has never been under regulatory or because it has been abandoned, lost, misplaced, stolen or transferred without proper authorization. In the last ten years a few international conferences were dedicated to the improvement of the safety and security of radioactive sources. Three main tasks are focused, the maintenance of data bases related to events with orphan sources and the publications of such events, the preparation of recommendations and guidelines to national regulatory bodies in order to prevent and detect the events related to orphan sources as well as to develop the response strategies to radiological or nuclear emergency, appraisals of the national strategies of radioactive sources control. Concerning Slovenia, strengthening control over orphan sources in Slovenia started after the adoption of new legislation in 2002. It was carried out through several tasks with the aim to prevent orphan sources, as well as to identify the sources which could be potentially orphan sources. The comprehensive methodology was developed by the Slovenian nuclear safety administration (S.N.S.A.) based on international guidelines as well as on the study of national lesson learned cases. The methodology was developed and used in close cooperation with all parties involved, namely other regulatory authorities, police, customs, agency for radioactive waste management (A.R.A.O.), technical support organisations (T.S.O.), users of source, authorised

    1990-01-01

    The author observes a resemblance between (1) the "polysemous" technique of imputing meaning to reality practiced in medieval biblical studies and in Dante's writing and (2) the technique of interpretation in contemporary psychoanalysis. She explores the roots of this resemblance in the development of intellectual history and provides examples of polysemous meanings in Dante's Divine Comedy, which is in part an autobiographical journey of self-reflection and self-realization (like psychoanalysis). She then suggests some implications of this resemblance for contemporary psychiatry.

    1993-01-01

    The plutonium processing facility at Los Alamos has adopted the strategic goal of becoming a facility that processes plutonium in a way that produces only environmentally benign waste streams. Pollution prevention through source reduction and environmentally sound recycling are being pursued. General approaches to waste reductions are administrative controls, modification of process technologies, and additional waste polishing. Recycling of waste materials, such as spent acids and salts, are technical possibilities and are being pursued to accomplish additional waste reduction. Liquid waste stream polishing to remove final traces of plutonium and hazardous chemical constituents is accomplished through (a) process modifications, (b) use of alternative chemicals and sorbents for residue removal, (c) acid recycling, and (d) judicious use of a variety of waste polishing technologies. Technologies that show promise in waste minimization and pollution prevention are identified. Working toward this goal of pollution prevention is a worthwhile endeavor, not only for Los Alamos, but for the Nuclear Complex of the future

    Full Text Available By energy sources we understand technologies and materials used to obtain various forms of energy necessary for the development of society. These sources must be in adequate quantities and be conveniently exploited in terms of technical, economic and sustainable perspective. Alternative energy uses the inherent power of natural sources like wind, tides, the sun. Alternative energy is a term used for some energy sources and energy storage technologies. Generally it indicates energies that are nontraditional and have low impact to the environment. The alternative energy term is used in contrast with the term fossil fuel according to some sources, while other sources use it with the meaning of renewable energy purposes.

  19. Language, meaning, and social cognition.

    Science.gov (United States)

    Holtgraves, Thomas M; Kashima, Yoshihisa

    2008-02-01

    Social cognition is meant to examine the process of meaningful social interaction. Despite the central involvement of language in this process, language has not received the focal attention that it deserves. Conceptualizing meaningful social interaction as the process of construction and exchange of meaning, the authors argue that language can be productively construed as a semiotic tool, a tool for meaning making and exchange, and that language use can produce unintended consequences in its users. First, the article shows a particular instance of language use to be a collaborative process that influences the representation of meaning in the speaker, the listener, and the collective that includes both the speaker and listener. It then argues that language use and social cognition may have reciprocal effects in the long run and may have significant implications for generating and maintaining cultural differences in social cognition.

    The Evolution of Meaning is based upon the premise that the Universe consists of information processing events. 'Information' is to be understood here not in the bare mathematical sense, but in the full active life/observation/meaning sense. From this viewpoint, the scientific description of Nature is seen to involve not only the fabric of spacetime, material aggregates and the forces acting between them, but also various equally real and fundamental groups of laws and law-like entities, as well as the concepts of subjectivity and value-oriented essential dimensi

    This paper revisits the derivation of the Lagrangian averaged Euler (LAE), or Euler-α equations in the light of an intrinsic definition of the averaged flow map as the geodesic mean on the volume-preserving diffeomorphism group. Under the additional assumption that first-order fluctuations are statistically isotropic and transported by the mean flow as a vector field, averaging of the kinetic energy Lagrangian of an ideal fluid yields the LAE Lagrangian. The derivation presented here assumes a Euclidean spatial domain without boundaries.

  5. Development of a clockwork light source to enable cervical inspection by village health workers

    2002-12-01

    Full Text Available Abstract Background Cervical cancer can often be prevented by screening and may be curable if identified and treated in its early stages. However, 80% of new cases occur in less-developed countries where cervical cancer screening programmes are small-scale or non-existent. This is a human tragedy of great proportion, with many of those affected being young mothers. There is some evidence that cancerous or precancerous lesions may be detected by visual inspection with acetic acid (VIA and field studies indicate that this technique is effective, safe and acceptable to women. However, the provision of a light source for inspection of the cervix presents a major problem in less-developed countries, where candles and torches often provide the only means of illumination. Our objective was to develop a light source based on clockwork technology, that required no batteries or external power source. Methods We adapted the design of a commercially available clockwork torch to provide a light source for cervical inspection. The light source was then tested under laboratory conditions in a comparison with other illumination methods typically used in this application. Results The light source gave illuminance levels greater than those produced by any other method tested, and also had considerable advantages in terms of ease of use and safety. Conclusion This design is small, compact, effective and safe to use and promises a better and more affordable means of visualising the cervix. Further field trials of VIA are now required which incorporate this light source.

    1984-01-01

    Ion beam V etching may give rise to undesirable effects such as uneven erosion and ion migration in dielectrics, even when the surface is neutralized by electron flooding. The effects appear due to a remaining charge imbalance on a microscopic scale, which is absent when bombarding with an uncharged beam. Saddle field sources provide a convenient means of producing energetic neutral beams of inert and reactive gases (which may be dissociated into radicals). The construction and characteristics of the sources are described and a mechanism of internal neutralization proposed. Evidence is given that uncharged beams introduce less damage than equivalent ion beams. Disruptive effects may be initiated by charge accumulation or possibly by neutralization processes which occur when ions closely approach the target surface. (author)

No language or year restrictions were used. Randomised controlled trials assessing the effects of xylitol products on dental caries in children and adults. Two review authors independently screened the results of the electronic searches, extracted data and assessed the risk of bias of the included studies. Authors were contacted where possible for missing data or clarification where feasible. For continuous outcomes, means and standard deviations were used to obtain the mean difference and 95% confidence interval (CI). Continuous data was used to calculate prevented fractions (PF) and 95% CIs to summarise the percentage reduction in caries. For dichotomous outcomes, reported risk ratios (RR) and 95% CIs were used. As there were fewer than four studies included in the meta-analysis, a fixed effect model was used. Ten studies were included with a total of 5903 participants. One study was assessed as being at low risk of bias, two were assessed as unclear risk of bias with seven at high risk of bias. Over 2.5–3 years, low quality evidence demonstrated that with 4216 children analysed, a fluoride toothpaste with 10% xylitol (exact dosage unsure) reduced caries by 13% when compared to a fluoride only toothpaste. (PF −0.13, 95% CI −0.18 to −0.08. Remaining evidence of the use of xylitol in children has risk of bias and uncertainty of effect and was therefore insufficient to determine a benefit from xylitol. Four studies reported that there were no adverse effects from any of the interventions. Two studies reported similar rates of adverse effects between study arms. The remaining studies either mentioned adverse effects

    Kratzke, Cynthia; Wilson, Susan; Vilchis, Hugo

    2013-02-01

    The purpose of this study was to examine the breast cancer prevention information seeking behaviors among rural women, the prevalence of Internet, cell, and text use, and interest to receive breast cancer prevention information cell and text messages. While growing literature for breast cancer information sources supports the use of the Internet, little is known about breast cancer prevention information seeking behaviors among rural women and mobile technology. Using a cross-sectional study design, data were collected using a survey. McGuire's Input-Ouput Model was used as the framework. Self-reported data were obtained from a convenience sample of 157 women with a mean age of 60 (SD = 12.12) at a rural New Mexico imaging center. Common interpersonal information sources were doctors, nurses, and friends and common channel information sources were television, magazines, and Internet. Overall, 87% used cell phones, 20% had an interest to receive cell phone breast cancer prevention messages, 47% used text messaging, 36% had an interest to receive text breast cancer prevention messages, and 37% had an interest to receive mammogram reminder text messages. Bivariate analysis revealed significant differences between age, income, and race/ethnicity and use of cell phones or text messaging. There were no differences between age and receiving text messages or text mammogram reminders. Assessment of health information seeking behaviors is important for community health educators to target populations for program development. Future research may identify additional socio-cultural differences.

  1. Astro research fellowship: low dose radiation to prevent restenosis after angioplasty

    International Nuclear Information System (INIS)

    Rege, Sheila; Razavi, Mahmood; Fessenden, Kali; Ziegler, Werner; Gomez, Antoinette; Smathers, James; Withers, Rodney

    1997-01-01

    Purpose: To determine the optimal time to deliver a single dose of external radiation therapy (12 Gy) postoperatively following balloon angioplasty (on same day, day 2 or day 4) to prevent restenosis in a non-stented swine model. To model an endovascular radioactive source for prevention of restenosis in the same animal model. Materials and Methods: Both external iliac arteries in eleven red duroc swine were injured using balloon overdilation (3 inflations, 60 secs. each, 16 psi), and the first five were additionally injured using denudation. One artery in each animal was then irradiated using anteroposterior and posterioranterior fields using Co-60 with 12 Gy prescribed to the midplane, with the other artery serving as a control. Irradiation was delivered on the same day, day 2 or day 4. Animals were sacrificed 3 months following injury, and histomorphometric analysis was performed. Additionally, a prototype endovascular beta source was designed and manufactured for clinical testing, based on Monte Carlo estimations. Results: Neointima formation was noted in both radiated and control arteries. The mean neointimal thickness in the radiated and control arteries was 116 ± 39 μm and 131 ± 47 μm respectively. Time of radiation delivery did not have a significant effect in preventing restenosis. Physical measurements of the endovascular source are in progress using a water based phantom. Animal testing will commence on ten red duroc swine. Conclusion: External radiation at this low dose does not appear to prevent restenosis in an unstented animal model. We hope to begin animal experiments using an endovascular source to prevent restenosis

    Mean-field games have been studied under the assumption of very large number of players. For such large systems, the basic idea consists of approximating large games by a stylized game model with a continuum of players. The approach has been shown to be useful in some applications. However, the stylized game model with continuum of decision-makers is rarely observed in practice and the approximation proposed in the asymptotic regime is meaningless for networks with few entities. In this paper, we propose a mean-field framework that is suitable not only for large systems but also for a small world with few number of entities. The applicability of the proposed framework is illustrated through various examples including dynamic auction with asymmetric valuation distributions, and spiteful bidders.

    Color may not only be pleasing to the eye, but may also carry important associations relevant for psychological functioning. Two experiments were conducted to test for basic hue-meaning associations, controlling for lightness and chroma. Specifically, we used a reaction time paradigm to test for links between red and green, and words that varied in achievement content (failure and success) or valence more generally. Results revealed that red was positively associated with failure and general negative words, and was negatively associated with success and general positive words, whereas green was positively associated with success words only. These findings directly document that hue carries psychologically relevant meaning. Implications both within and beyond the achievement domain are discussed.

    2009-01-01

    This paper and its associated series of slides review the experimental facilities and the simulation means used for the development of nuclear reactors in France. These experimental facilities include installations used for the measurement and qualification of nuclear data (mainly cross-sections) like EOLE reactor and Minerve zero power reactor, installations like material testing reactors, installations dedicated to reactor safety experiments like Cabri reactor, and other installations like accelerators (Jannus accelerator, GANIL for instance) that are complementary to neutron irradiations in experimental reactors. The simulation means rely on a series of advanced computer codes: Tripoli-Apollo for neutron transport, Numodis for irradiation impact on materials, Neptune and Cathare for 2-phase fluid dynamics, Europlexus for mechanical structures, and Pleiades (with Alcyone) for nuclear fuels.

    This article explores the legal meanings of biopiracy concept, linked to subjects such as intellectual property rights on genetic resources, bioprospecting contracts, right to food, and food security. It overcomes the critical function of biopiracy concept related to world-wide extended tendencies: privatization and technification. Likewise, protectionism shows the opportunity that biopiracy concept represents for the enrichment of the legal interpretation related to the bioethical statue of biotech developments.

  8. MEANS FOR TERMINATING NUCLEAR REACTIONS

    Science.gov (United States)

    Cooper, C.M.

    1959-02-17

    An apparatus is presented for use in a reactor of the heterogeneous, fluid cooled type for the purpose of quickly terminating the reaction, the coolant being circulated through coolant tubes extending through the reactor core. Several of the tubes in the critical region are connected through valves to a tank containing a poisoning fluid having a high neutron capture crosssection and to a reservoir. When it is desired to quickly terminate the reaction, the valves are operated to permit the flow of the poisoning fluid through these particular tubes and into the reservoir while normal coolant is being circulated through the remaining tubes. The apparatus is designed to prevent contamination of the primary coolant by the poisoning fluid.

    We introduce embedded mean-field theory (EMFT), an approach that flexibly allows for the embedding of one mean-field theory in another without the need to specify or fix the number of particles in each subsystem. EMFT is simple, is well-defined without recourse to parameters, and inherits the simple gradient theory of the parent mean-field theories. In this paper, we report extensive benchmarking of EMFT for the case where the subsystems are treated using different levels of Kohn-Sham theory, using PBE or B3LYP/6-31G* in the high-level subsystem and LDA/STO-3G in the low-level subsystem; we also investigate different levels of density fitting in the two subsystems. Over a wide range of chemical problems, we find EMFT to perform accurately and stably, smoothly converging to the high-level of theory as the active subsystem becomes larger. In most cases, the performance is at least as good as that of ONIOM, but the advantages of EMFT are highlighted by examples that involve partitions across multiple bonds or through aromatic systems and by examples that involve more complicated electronic structure. EMFT is simple and parameter free, and based on the tests provided here, it offers an appealing new approach to a multiscale electronic structure.

  10. Keep Meaning in Conversational Coordination

    Directory of Open Access Journals (Sweden)

    Elena Clare Cuffari

    2014-12-01

    Full Text Available Coordination is a widely employed term across recent quantitative and qualitative approaches to intersubjectivity, particularly approaches that give embodiment and enaction central explanatory roles. With a focus on linguistic and bodily coordination in conversational contexts, I review the operational meaning of coordination in recent empirical research and related theorizing of embodied intersubjectivity. This discussion articulates what must be involved in treating linguistic meaning as dynamic processes of coordination. The coordination approach presents languaging as a set of dynamic self-organizing processes and actions on multiple timescales and across multiple modalities that come about and work in certain domains (those jointly constructed in social, interactive, high-order sense-making. These processes go beyond meaning at the level that is available to first-person experience. I take one crucial consequence of this to be the ubiquitously moral nature of languaging with others. Languaging coordinates experience, among other levels of behavior and event. Ethical effort is called for by the automatic autonomy-influencing forces of languaging as coordination.

  11. [Prevention of dementia].

    Urakami, Katsuya

    2016-03-01

    The dementia prevention consists of three steps, primary prevention of dementia is to prevent from normal and mild cognitive impairment to dementia, secondary prevention is early detection and early treatment of dementia, and tertiary prevention is three stages of progress prevention of dementia. Primary prevention of dementia had been considered impossible until recently, but potential scientific evidence has been shown recently. The fact that 4.62 million people are person with dementia and 400 million people are person with mild cognitive impairment are considered to be urgent problem and we must intend to perform dementia prevention from primary to tertiary prevention thoroughly. We perform dementia screening using touch panel type computer and we recommend person with mild cognitive impairment to join dementia prevention classroom. Therefore, we can prevent progression from mild cognitive impairment to dementia (primary prevention). Early diagnosis and introduction to the specialized medical institution are needed if you find early stage of dementia and treat early (secondary prevention). To prevent progression by the appropriate drug treatment and care for dementia is required (tertiary prevention).

  12. Dynamical Predictability of Monthly Means.

    Shukla, J.

    1981-12-01

    We have attempted to determine the theoretical upper limit of dynamical predictability of monthly means for prescribed nonfluctuating external forcings. We have extended the concept of `classical' predictability, which primarily refers to the lack of predictability due mainly to the instabilities of synoptic-scale disturbances, to the predictability of time averages, which are determined by the predictability of low-frequency planetary waves. We have carded out 60-day integrations of a global general circulation model with nine different initial conditions but identical boundary conditions of sea surface temperature, snow, sea ice and soil moisture. Three of these initial conditions are the observed atmospheric conditions on 1 January of 1975, 1976 and 1977. The other six initial conditions are obtained by superimposing over the observed initial conditions a random perturbation comparable to the errors of observation. The root-mean-square (rms) error of random perturbations at all the grid points and all the model levels is 3 m s1 in u and v components of wind. The rms vector wind error between the observed initial conditions is >15 m s1.It is hypothesized that for a given averaging period, if the rms error among the time averages predicted from largely different initial conditions becomes comparable to the rms error among the time averages predicted from randomly perturbed initial conditions, the time averages are dynamically unpredictable. We have carried out the analysis of variance to compare the variability, among the three groups, due to largely different initial conditions, and within each group due to random perturbations.It is found that the variances among the first 30-day means, predicted from largely different initial conditions, are significantly different from the variances due to random perturbations in the initial conditions, whereas the variances among 30-day means for days 31-60 are not distinguishable from the variances due to random initial

    Full Text Available Introduction: Osteoporosis prevention is heavily reliant on education programs, which are most effective when tailored to their intended audience. Most osteoporosis prevention education is designed for older adults, making application of these programs to younger adults difficult. Designing programs for young adults requires understanding the information-seeking practices of young adults, so that knowledge about osteoporosis can be effectively translated. Methods: Individual interviews were conducted with 60 men and women—multiethnic, Canadian young adults—to explore both the sources and types of information they search for when seeking information on nutrition or bone health. Results: The results of this study raised themes related to the sources participants use, to their interests and to ways of engaging young adults. Prevention programs should make use of traditional sources, such as peers, family members and medical professionals, as well as emerging technologies, such as social media. Choice of sources was related to the perceived authority of and trust associated with the source. Messaging should relate to young adult interests, such as fitness and food—topics on which young adults are already seeking information—rather than being embedded within specific osteoporosis awareness materials. Engaging young adults means using relatable messages that are short and encourage small changes. Small gender-based differences were found in the information-seeking interests of participants. Differences related to age were not examined. Conclusion: Creating short, action-oriented messages that are designed to encourage small changes in behaviour and are packaged with information that young adults are actively seeking is more likely to result in active engagement in prevention behaviours.

    The discussion of "error" has gained momentum in forensic science in the wake of the Daubert guidelines and has intensified with the National Academy of Sciences' Report. Error has many different meanings, and too often, forensic practitioners themselves as well as the courts misunderstand scientific error and statistical error rates, often confusing them with practitioner error (or mistakes). Here, we present an overview of these concepts as they pertain to forensic science applications, discussing the difference between practitioner error (including mistakes), instrument error, statistical error, and method error. We urge forensic practitioners to ensure that potential sources of error and method limitations are understood and clearly communicated and advocate that the legal community be informed regarding the differences between interobserver errors, uncertainty, variation, and mistakes. © 2013 American Academy of Forensic Sciences.

    has been compared to the standard hospital bed as well as to two other commercially available pressure relief mattresses. The most recent advance in pressure ulcer prevention is the development of the ALTERN8* seating system. This seating system provides regular periods of pressure relief and stimulation of blood flow to skin areas while users are seated. By offering the combination of pressure relief therapy and an increase in blood flow, the ALTERN8* reportedly creates an optimum pressure ulcer healing environment. Foam is the most commonly used material for pressure reduction and pressure ulcer prevention and treatment for the mobile individual. For those immobilized individuals who can achieve a passive standing position, a powered wheelchair that allows the individual to achieve a passive standing position is recommended. The beneficial effects of passive standing have been documented by comprehensive scientific studies. These benefits include reduction of seating pressure, decreased bone demineralization, increased blander pressure, enhanced orthostatic circulatory regulation, reduction in muscular tone, decrease in upper extremity muscle stress, and enhanced functional status in general. In the absence of these dynamic alternating pressure seating systems and mattresses, there are enormous medicolegal implications to the healthcare facility. Because there is not sufficient staff to provide pressure relief to rotate the patient every 2 hours in a hospital setting, with the exception of the intensive care unit, the immobile patient is prone to develop pressure ulcers. The cost of caring for these preventable pressure ulcers may now be as high as 60,000 dollars per patient. The occupational physical strain sustained by nursing personnel in rotating their patients has led to occupational back pain in nurses, a major source of morbidity in the healthcare environment.

    Nydia Stella Caicedo Martínez

    Full Text Available Objective.This work sought to analyze how educational processes have been developed for breastfeeding in a health institution, starting from the meanings mothers, families, and health staff construct thereon. Methods. This was qualitative research of ethnographic approach, which included observations during the group educational activities of the programs, focal groups, and interviews of mothers, their families, and the health staff of a hospital unit in the city of Medellín, Colombia. The analysis was guided by the constant comparison method. Results. The categories emerging from the data were: 1 breast milk is an ideal food. 2 The mothers' experiences influence upon the breastfeeding practice. 3 Family beliefs sometimes operate as cultural barriers. 4 Disagreements are revealed in the educational process. Conclusion. The way educational processes have taken place for breastfeeding reveals a break expressed by the scarce interaction between the meanings professionals have constructed on the topic and those the mothers and their families give to the experience of breastfeeding.

  8. Mean field games with congestion

    Achdou, Yves; Porretta, Alessio

    2018-03-01

    We consider a class of systems of time dependent partial differential equations which arise in mean field type models with congestion. The systems couple a backward viscous Hamilton-Jacobi equation and a forward Kolmogorov equation both posed in $(0,T)\\times (\\mathbb{R}^N /\\mathbb{Z}^N)$. Because of congestion and by contrast with simpler cases, the latter system can never be seen as the optimality conditions of an optimal control problem driven by a partial differential equation. The Hamiltonian vanishes as the density tends to $+\\infty$ and may not even be defined in the regions where the density is zero. After giving a suitable definition of weak solutions, we prove the existence and uniqueness results of the latter under rather general assumptions. No restriction is made on the horizon $T$.

    Aim of the work was to describe the noninvasive assessment of bone mineral density, geometrical and biochemical properties in premenopausal women with dietary intake of phytoestrogens and comparison of these parameters with those of age-matched female subjects with Mediterranean dietary intake lacking in these substances. Volumetric cortical, trabecular and total mineral density and bone geometrical properties were evaluated with peripheral quantitative computed tomography (pQCT) at the distal radius of the non dominant forearm. pQCT showed higher bone mineral density (total and trabecular) and SSI values in premenopausal with dietary intake of phytoestrogens. Despite the lack of statistical significance, these preliminary results, should further support the few literature findings about the potential role of phytoestrogens consumption in preventing trabecular bone loss. However, further studies are warranted to evaluate definitively postmenopausal osteoporosis. [Italian] Scopo del lavoro e' quello di studiare in modo non-invasivo la densita' minerale, le caratteristiche geometriche e biomeccaniche dell'osso in donne lattoovovegetariane nella premenopausa che assumevano con la dieta fitoestrogeni e confrontare questi dati con quelli di donne anch'esse in premenopausa, con dieta di tipo mediterraneo assolutamente priva di questi elementi con azione simil-ormonale. La densita' minerale, le proprieta' geometriche meccaniche dell'osso sono state valutate a livello del radio ultradistale non dominante mediante tomografia computerizzata (TC) quantitativa periferica, che nelle donne in premenopausa con dieta ricca di fitoestrogeni ha evidenziato valori della densita' minerale ossea totale, trabecolare e di resistenza ossea piu' elevati, anche se in modo non significativo, rispetto a quelli dei controlli con dieta mediterranea. Questi risultati preliminari suggerirebbero come l'assunzione quotidiana di fitoestrogeni

    This paper describes the effort of the Center for Development of Radioactive Waste Management (CDRWM) to develop and implement activities in maintaining and improving the safety of spent sealed radiation sources and the security of radioactive materials over their life cycle. There is a wide variety of uses of radiation sources and radioactive materials in Indonesia, while the CDRWM plan to cover all spent radiation sources. Primary consideration is given to sealed radiation sources with relatively high levels of radioactivity which might necessitate interventional measures should control over them be lost. The policy of the Government of Indonesia for spent radiation sources is, whenever possible, spent sealed sources should be returned to the supplier. CDRWM has a general principle that sealed sources should not be removed from their holders, or the holders physically modified (except for Ra-226 needles, smoke detector and lighting preventer).

  18. Trying to prevent abortion.

    Science.gov (United States)

    Bromham, D R; Oloto, E J

    1997-06-01

    It is known that, since antiquity, women confronted with an unwanted pregnancy have used abortion as a means of resolving their dilemma. Although undoubtedly widely used in all historical ages, abortion has come to be regarded as an event preferably avoided because of the impact on the women concerned as well as considerations for fetal life. Policies to reduce numbers and rates of abortion must acknowledge certain observations. Criminalization does not prevent abortion but increases maternal risks. A society's 'openness' in discussing sexual matters inversely correlates with abortion rates. Correlation between contraceptive use and abortion is also inverse but relates most closely to the efficacy of contraceptive methods used. 'Revolution' in the range of contraceptive methods used will have an equivalent impact on abortion rates. Secondary or emergency contraceptive methods have a considerable role to play in the reduction of abortion numbers. Good sex (and 'relationships') education programs may delay sexual debut, increase contraceptive usage and be associated with reduced abortion. Finally, interaction between socioeconomic factors and the choice between abortion and ongoing pregnancy are complex. Abortion is not necessarily chosen by those least able to support a child financially.

  19. Mean Field Analysis of Quantum Annealing Correction.

    Science.gov (United States)

    Matsuura, Shunji; Nishimori, Hidetoshi; Albash, Tameem; Lidar, Daniel A

    2016-06-03

    Quantum annealing correction (QAC) is a method that combines encoding with energy penalties and decoding to suppress and correct errors that degrade the performance of quantum annealers in solving optimization problems. While QAC has been experimentally demonstrated to successfully error correct a range of optimization problems, a clear understanding of its operating mechanism has been lacking. Here we bridge this gap using tools from quantum statistical mechanics. We study analytically tractable models using a mean-field analysis, specifically the p-body ferromagnetic infinite-range transverse-field Ising model as well as the quantum Hopfield model. We demonstrate that for p=2, where the phase transition is of second order, QAC pushes the transition to increasingly larger transverse field strengths. For p≥3, where the phase transition is of first order, QAC softens the closing of the gap for small energy penalty values and prevents its closure for sufficiently large energy penalty values. Thus QAC provides protection from excitations that occur near the quantum critical point. We find similar results for the Hopfield model, thus demonstrating that our conclusions hold in the presence of disorder.

  20. True mean rate measuring system

    International Nuclear Information System (INIS)

    Eichenlaub, D.P.

    1980-01-01

    A digital radiation-monitoring system for nuclear power plants uses digital and microprocessor circuitry to enable rapid processing of pulse information from remote radiation monitors. The pulse rates are analyzed to determine whether new pulse-rate information is statisticaly the same as that previously received and to determine the best possible averaging time, which can be changed so that the statistical error remains below a specified level while the system response time remains short. Several data modules each process the pulse-rate information from several remote radiation monitors. Each data module accepts pulse data from each radiation monitor and measures the true average or mean pulse rate of events occurring with a Poisson distribution to determine the radiation level. They then develop digital output signals which indciate the respective radiation levels and which can be transmitted via multiplexer circuits for additional processing and display. The data modules can accept signals from remote control stations or computer stations via the multiplexer circuit to change operating thresholds and alarm levels in their memories. A check module scans the various data modules to determine whether the output signals are valid. It also acts as a redundant data module and will automatically replace an inoperative unit. (DN)

In its broua aspects, the mer would around ce of reference tedtor means also itons in the phase ition of the An electronic circuit for conversion of excess-3 binary coded serial decimal numbers to straight binary coded serial decimal numbers is reported. The converter of the invention in its basic form generally coded pulse words of a type having an algebraic sign digit followed serially by a plurality of decimal digits in order of decreasing significance preceding a y algebraic sign digit followed serially by a plurality of decimal digits in order of decreasing significance. A switching martix is coupled to said input circuit and is internally connected to produce serial straight binary coded pulse groups indicative of the excess-3 coded input. A stepping circuit is coupled to the switching matrix and to a synchronous counter having a plurality of x decimal digit and plurality of y decimal digit indicator terminals. The stepping circuit steps the counter in synchornism with the serial binary pulse group output from the switching matrix to successively produce pulses at corresponding ones of the x and y decimal digit indicator terminals. The combinations of straight binary coded pulse groups and corresponding decimal digit indicator signals so produced comprise a basic output suitable for application to a variety of output apparatus.

  2. Meaning in life and intuition.

    Heintzelman, Samantha J; King, Laura A

    2016-03-01

    Three correlational studies and 2 experiments examined the association between meaning in life (MIL) and reliance on intuitive information processing. In Studies 1-3 (total N = 5,079), Faith in Intuition (FI) scale and MIL were correlated positively, controlling for religiosity, positive mood, self-esteem, basic need satisfaction, and need for cognition. Two experiments manipulated processing style. In Study 4 (N = 614), participants were randomly assigned to complete the Cognitive Reflection Task (CRT; Fredrick, 2005) either immediately before (reflective/low intuitive mindset condition) or immediately after (control condition) rating MIL. Condition did not affect MIL. However, low MIL rated before the CRT predicted superior performance and greater time spent on the task. The association between reflection and MIL was curvilinear, such that MIL was strongly negatively related to CRT performance particularly at low levels of MIL. In Study 5 (N = 804), intuitive or reflective mindsets were induced and FI and MIL were measured. Induced processing style study did not affect MIL. However, those high in MIL were more responsive to the intuitive mindset induction. The relationship between FI and MIL was curvilinear (in this and the correlational studies), with intuitive processing being strongly positively related to MIL particularly at higher levels of MIL. Although often considered in the context of conscious reflection, MIL shares a positive relationship with reliance on gut feelings, and high MIL may facilitate reliance on those feelings.

  3. The meaning of quantum gravity.

    von Borzeszkowski, H.-H.; Treder, H.-J.

    Should the general theory of relativity be quantized? Indeed, can the general theory of relativity be quantized? These two questions are central to modern physics. The authors of this book take the Bohr-Rosenfeld analysis of quantum electrodynamics as their starting point and develop arguments in support of Einstein's own thesis that, due to the validity of the strong principle of equivalence, the general theory cannot be rigorously quantized. They show that the concept of gravitons is an approximate formalization only, which has its use in the harmonization of the gravitational equations with the matter field, but which does not predict any effect that may be used to distinguish quantum from classical gravity.Contents: 1.

    The quality of the prevention of eating disorders represents in several last decades frequently discussed issue in the context of rapidly changing socio-economic conditions, a significant increase of influence of the media, new technologies and knowledge of risk factors. Primary prevention aims to reduce the risk of developing eating disorders, but secondary and tertiary prevention play the important role as well. Effective and coordinated prevention is still missing. Our experience of international cooperation of the last 20 years led to the development and evaluation of prevention programs. We are describing their fast development and ongoing programs following the new trends recommended by WHO.

    We present *K-means clustering algorithm and source code by expanding statistical clustering methods applied in https://ssrn.com/abstract=2802753 to quantitative finance. *K-means is statistically deterministic without specifying initial centers, etc. We apply *K-means to extracting cancer signatures from genome data without using nonnegative matrix factorization (NMF). *K-means' computational cost is a fraction of NMF's. Using 1389 published samples for 14 cancer types, we find that 3 cancers (liver cancer, lung cancer and renal cell carcinoma) stand out and do not have cluster-like structures. Two clusters have especially high within-cluster correlations with 11 other cancers indicating common underlying structures. Our approach opens a novel avenue for studying such structures. *K-means is universal and can be applied in other fields. We discuss some potential applications in quantitative finance.

    2009-12-01

    Full Text Available Abstract Background Road traffic injuries (RTIs are a major public health problem, especially in low- and middle-income countries. Among middle-income countries, Iran has one of the highest mortality rates from RTIs. Action is critical to combat this major public health problem. Stakeholders involved in RTI control are of key importance and their perceptions of barriers and facilitators are a vital source of knowledge. The aim of this study was to explore barriers to the prevention of RTIs and provide appropriate suggestions for prevention, based on the perceptions of stakeholders, victims and road-users as regards RTIs. Methods Thirty-eight semi-structured interviews were conducted with informants in the field of RTI prevention including: police officers; public health professionals; experts from the road administrators; representatives from the General Governor, the car industry, firefighters; experts from Emergency Medical Service and the Red Crescent; and some motorcyclists and car drivers as well as victims of RTIs. A qualitative approach using grounded theory method was employed to analyze the material gathered. Results The core variable was identified as "The lack of a system approach to road-user safety". The following barriers in relation to RTI prevention were identified as: human factors; transportation system; and organizational coordination. Suggestions for improvement included education (for the general public and targeted group training, more effective legislation, more rigorous law enforcement, improved engineering in road infrastructure, and an integrated organization to supervise and coordinate preventive activities. Conclusion The major barriers identified in this study were human factors and efforts to change human behaviour were suggested by means of public education campaigns and stricter law enforcement. However, the lack of a system approach to RTI prevention was also an important concern. There is an urgent need for both

  7. Crisis of Meaning Predicts Suicidality in Youth Independently of Depression.

    2018-02-23

    At times, the question for meaning comes to nothing and a crisis of meaning ensues. This state is very painful, but difficult to account. Both those who suffer from it and care professionals find themselves at a loss for words. This study introduces an operationalization of a crisis of meaning. It aims to distinguish the concept from depression, and to investigate whether a crisis of meaning can explain suicidality beyond the known protective and risk factors self-esteem, family functioning, life-event load, and depression. Final-year school pupils in Ecuador (N = 300) completed questionnaires assessing the above variables. Data were analyzed using chi-square, hierarchic multiple regression, serial mediation, and moderator analyses. Crisis of meaning was distinguished from depression. It explained a significant amount of variance in suicidality beyond the mentioned protective and risk factors. For males, crisis of meaning was the only significant risk factor, and the strongest predictor overall. The acute risk factors depression and crisis of meaning mediated the effects of the baseline factors self-esteem, family functioning, and life-event load on suicidality. The study was cross-sectional; assessed factors predicted variance in suicidal thoughts, plans, and past suicide attempts, while their relevance cannot be generalized to actual future suicide attempts. A crisis of meaning is an important factor to take into account in further research on the prevention and treatment of people at risk of suicide.

  9. Prevention Of Stroke

    Directory of Open Access Journals (Sweden)

    Nagaraja D

    2005-01-01

    Full Text Available Stroke is an important cause for neurological morbidity and mortality. Prevention of ischemic stroke involves identification and prevention of risk factors and optimal use of pharmacotherapy. Risk factors have been classified as modifiable and non-modifiable; control of modifiable factors should prevent stroke occurrence. Stroke prevention has been described at three levels: primary, secondary and tertiary. Prolonged hypertension increases an individual′s risk for developing fatal or nonfatal stroke by three times and its control has been shown to prevent stroke. Diabetes mellitus is an important cause for microangiopathy and predisposes to stroke. Statin trials have shown significant reduction in stroke in those who were treated with statins. Stroke risk can be reduced by avoiding tobacco use, control of obesity and avoiding sedentary life style. Anti platelet medications are effective for secondary prevention of stroke. Educating society regarding modifiable risk factors and optimal use of pharmacotherapy form the cornerstone for the prevention of stroke.

  10. Make your values mean something.

    Science.gov (United States)

    Lencioni, Patrick M

    2002-07-01

    Take a look at this list of corporate values: Communication. Respect. Integrity. Excellence. They sound pretty good, don't they? Maybe they even resemble your own company's values. If so, you should be nervous. These are the corporate values of Enron, as claimed in its 2000 annual report. And they're absolutely meaningless. Indeed, most values statements, says the author, are bland, toothless, or just plain dishonest. And far from being harmless, as some executives assume, they're often highly destructive. Empty values statements create cynical and dispirited employees and undermine managerial credibility. But coming up with strong values--and sticking to them--isn't easy. Organizations that want their values statements to really mean something should follow four imperatives. First, understand the different types of values: core, aspirational, permission-to-play, and accidental. Confusing them with one another can bewilder employees and make management seem out of touch. Second, be aggressively authentic. Too many companies view a values initiative in the same way they view a marketing launch: a onetime event measured by the initial attention it receives, not by its content. Third, own the process. Values initiatives are about imposing a set of fundamental, strategically sound beliefs on a broad group of people. That's why the best values efforts are driven by small teams. Finally, weave core values into everything. It's not enough to hang your values statement on the wall; it must be integrated into every employee-related process--hiring methods, performance management systems, even dismissal policies. Living by stated corporate values is difficult. But the benefits of doing so can be profound; so can the damage from adopting a hollow set of corporate values.

  11. Suicide Prevention Strategies for Improving Population Health.

    Wilcox, Holly C; Wyman, Peter A

    2016-04-01

    Suicide is a public health problem that accounts for more than 1 million deaths annually worldwide. This article addresses evidence-based and promising youth suicide prevention approaches at the primary, secondary, and tertiary levels. Coordinated, developmentally timed, evidence-based suicide prevention approaches at all intervention levels are likely to reduce youth suicide. For most youth who die by suicide, there are opportunities for intervention before imminent risk develops. Current research in suicide prevention points to the value of investing in "upstream" universal interventions that build skills and resilience as well as policies that enable access to care and protection from lethal means.

  12. Primary prevention of colorectal cancer.

    Science.gov (United States)

    Chan, Andrew T; Giovannucci, Edward L

    2010-06-01

    Colorectal cancer has been strongly associated with a Western lifestyle. In the past several decades, much has been learned about the dietary, lifestyle, and medication risk factors for this malignancy. Although there is controversy about the role of specific nutritional factors, consideration of dietary pattern as a whole appears useful for formulating recommendations. For example, several studies have shown that high intake of red and processed meats, highly refined grains and starches, and sugars is related to increased risk of colorectal cancer. Replacing these factors with poultry, fish, and plant sources as the primary source of protein; unsaturated fats as the primary source of fat; and unrefined grains, legumes and fruits as the primary source of carbohydrates is likely to lower risk of colorectal cancer. Although a role for supplements, including vitamin D, folate, and vitamin B6, remains uncertain, calcium supplementation is likely to be at least modestly beneficial. With respect to lifestyle, compelling evidence indicates that avoidance of smoking and heavy alcohol use, prevention of weight gain, and maintenance of a reasonable level of physical activity are associated with markedly lower risks of colorectal cancer. Medications such as aspirin and nonsteroidal anti-inflammatory drugs and postmenopausal hormones for women are associated with substantial reductions in colorectal cancer risk, though their utility is affected by associated risks. Taken together, modifications in diet and lifestyle should substantially reduce the risk of colorectal cancer and could complement screening in reducing colorectal cancer incidence.

    2003-09-01

    In 1998, a school-based blood lead level (BLL) survey of 2,510 children, conducted in Lima and Callao, Peru, revealed elevated BLLs in children from 2 Callao schools (mean BLL = 25.6 microg/dl; n = 314) and in children from Callao overall (mean BLL = 15.2 microg/dl; n = 898), compared with children from Lima (mean BLL = 7.1 microg/dl; n = 1,612). Public health officials at Peru's Direccion General de Salud Ambiental (DIGESA) hypothesized that a possible source of the elevated pediatric BLLs observed in Callao was a large depository near the port where mineral concentrates are stored prior to shipment. The U.S. Centers for Disease Control and Prevention worked with DIGESA to identify source(s) that contributed to the pediatric lead poisonings by comparing isotopic profiles of lead in blood, mineral, gasoline, and air filter samples. The lead isotope ratio (IR) observed in mineral samples from the depository in Callao differed from those in gasoline samples from Lima and Callao. The blood lead IRs of children living near the depository were similar to the IRs of the mineral samples and different from the IRs of the gasoline samples, suggesting that lead from the depository-and not gasoline-was the primary source of lead in these children. Lead IR analysis of regional air filter samples supported these findings.

    -centred menu and offering a new updated, attractive, student-centred approach to teaching and learning physics. The approach will be one where teaching is supported by innovative teaching materials, enabling students to work in groups, to role-play, to research and problem-solve, to design using mathematical models, to learn about physics beyond their classrooms, to develop key skills and to speak about physics with an enthusiasm and sparkle. Yes, I too can dream, but if you don't aim for the stars, as the saying goes, you will not even reach the top of the mountain. The inclusion of topics like astrophysics, cosmology and particle physics in syllabus structures is to be applauded for offering young people a broader vision of physics. However, they are all developments which attempt to influence the content of a physics syllabus. The debate has been whether or not to include the fourth-power law in an astrophysics unit or whether refractive index has a place in Medical Physics to explain optical fibre technology. What has been missing as far as I can see has been a parallel movement in developing the way Physics has been taught, can be taught and can be studied. The time for funding new initiatives which will develop the methodology of teaching and learning physics is now. It is over 20 years since I used the teacher's pages of the old Nuffleld Advanced books to give me ideas on how to teach the course as a probationer (NQT). I still find myself referring to them on occasion. In the intervening years we have learnt much about how young people learn science and how older people teach science. So here is a message to the physics education community. By all means fund projects to introduce some modern physics into the curriculum but hear this plea for parallel developments in new ways to teach the new, and the old, physics - ways that will cater for broad ability ranges and for the diverse career interests of students and will allow teachers to adjust their focus away from the

    We have implemented k-means clustering, hierarchical clustering and self-organizing maps in a single multipurpose open-source library of C routines, callable from other C and C++ programs. Using this library, we have created an improved version of Michael Eisen's well-known Cluster program for Windows, Mac OS X and Linux/Unix. In addition, we generated a Python and a Perl interface to the C Clustering Library, thereby combining the flexibility of a scripting language with the speed of C. The C Clustering Library and the corresponding Python C extension module Pycluster were released under the Python License, while the Perl module Algorithm::Cluster was released under the Artistic License. The GUI code Cluster 3.0 for Windows, Macintosh and Linux/Unix, as well as the corresponding command-line program, were released under the same license as the original Cluster code. The complete source code is available at http://bonsai.ims.u-tokyo.ac.jp/mdehoon/software/cluster. Alternatively, Algorithm::Cluster can be downloaded from CPAN, while Pycluster is also available as part of the Biopython distribution.

    The motive for the realization of the program prevention of the dependence on at primary school, is the knowledge that in our country last years the mental health of children and young endangered also the war which always represents the factor of high risk for psychic development and health. The experiences show that without collaboration between the different experts who are treating with the children and the adolescents has no efficacious prevention, protection, and treatment of dependence on. The better knowing of the normal psychic development leads to better knowing of the disorders and increases the successfulness of the intervention. In this paper is demonstrated the model of the program of the prevention of the dependances applied at the primary school "Edhem Mulabdich". The realization of this program ran through two phases: I-"educator education" for the teachers of the class and subject teaching and II-training program for the selected group of the teachers carriers of the preventive activities. This program we concipated so that through the structurized activities realize the following tasks: education from the different fields of the relevant for the problem of dependency, the development of the skills of the recognition of the pupils for the use of the means of dependensies: The animiting of the school environment so that the problem of dependency on the adequate manner would build in into the regular school activities the development of the expert net and institutions which will intervene in the definite cases. The application of this model for the prevention program of dependency pointed to the possibilities of the efficacious acting at school conditions, with the obligation that in the efficacious acting in school condition, with the obligation that in during the continued application the permanent gets tested, complete and adapt appropriately the requests of the community and scientific knowledges.

    Hydrocarbons are at present the single most important source of energy, since they are the most versatile and widely used. It is expected that their importance will extend well into the next century and therefore it is essential to provide for all those improvements which will extend their availability and usefulness. The sub-programme ''Optimization of the production and utilization of hydrocarbons'' (within the Non-Nuclear Energy R and D Programme of the European Communities) is pursuing a number of R and D topics aimed at the above-mentioned results. It is implemented by means of shared-cost R and D contracts. At this first Seminar held in Lyon (France) from 21-23 September, 1988, all contractors of the sub-programme presented the state of progress of their R and D projects. These proceedings comprise all the papers presented at the Seminar. The section on oilfield exploration includes a report of work on the interpretation of nuclear logs by means of mathematical models. (author)

    Radioactive sources are used throughout the world for a wide variety of peaceful purposes in industry, medicine, agriculture, research and education. It has been recognized that unsecured radioactive sources can cause serious radiological accidents involving radiation injuries and fatalities. Radioactive source after its useful life, although considered waste, can still pose a security threat if not managed properly. Today, there is a growing concern that terrorist or criminal groups could gain access to disused high activity radioactive sources and use it with harmful intent. Consequently, there has been a global trend towards increased control, accounting, and security measures to prevent such incidents. Particular concern is expressed regarding radioactive sources that have become orphaned (not under regulatory control) or vulnerable (under weak regulatory control and about to be orphaned). The International Basic Safety Standards published by International Atomic Energy Agency (IAEA) provide an internationally harmonized basis for ensuring the safe and secure use of sources of ionizing radiation

Optical methods for charged particle beam monitoring are shown to ensure operative and precise monitoring the number of particles and particle energy. SR sources with large axial dimensions of an electron beam have specific spectral angular and polarization characteristics. If electron angular distribution at deflection from the median plane is noticeably wider than angular distribution of SR of a certain electron, relative SR characteristics of these soUrces are calculated with high accuracy

    Groundwater contamination prevention mapping is an important component of groundwater contamination geological survey and assessment work, which could provide the basis for making and implementing groundwater contamination prevention planning. A groundwater contamination prevention mapping system was constructed in view of the synthetic consideration on nature perspective derived from groundwater contamination sources and aquifer itself, social-economic perspective, policy perspective derived from outside. During the system construction process, analytic hierarchy process and relevant overlaying principles were used to couple groundwater contamination risk assessment, groundwater value as well as wellhead protection area zoning. Data processing and visualization of mapping results were achieved in the GIS environment. The research on groundwater contamination prevention mapping in Beijing Plain indicated that the final groundwater prevention map was in accordance with the actual conditions and well reflected the priorities of groundwater prevention, which could play a guidance role in designing and implementing further practical prevention and supervision measures. Besides, because of the dynamical properties of the system components, it was suggested to analyze the update frequency of the mapping.

    Valid, sustained and safe clinical means of colorectal cancer prevention are still lacking, but they are urgently needed to lower the incidence of colorectal cancer. Dietary factors and phytochemicals such as flavonoids play an important role for prevention. A selective search of the literature using PubMed was performed with the following key words: flavonoids, cancer, therapy, colorectal cancer focused on clinical queries. Results of clinical studies including the authors' own were compared. In vivo and in vitro studies with animals, cell cultures and subcellular components provide ample evidence for antimutagenic and anticarcinogenic effects of flavonoids as shown for multiple biological and molecular endpoints. Isoflavonoids in vitro have been shown to induce proliferation of breast cancer cells. Epidemiologic trials (cohort, case-control and cross-sectional studies) yielded inconsistent results for flavonoid protection. Systematic reviews and meta-analyses support the protective role of tea flavonoids on adenoma incidence. An interventional pilot study with sustained flavonoid supplementation was shown to reduce the rate of neoplasia in patients with resected colorectal cancer. Selected flavonoids possess antimutagenic and anticarcinogenic properties and could reduce the incidence of colorectal neoplasias as shown in epidemiologic trials. Randomized controlled clinical studies with flavonoid intervention are necessary to provide evidence for their role in colorectal cancer prevention.

    Results: There are five primary functions of management as: Anticipate and plan, organize, command, coordinate and control. If we introduce the following definition in the sense of medical science and apply it to the medical practice that would mean way of recognizing, managing and resolving issues of diagnosis and therapy of diseases (in this case gynecology diseases according to certain guidelines and treatment algorithms. Treatment of family doctors is an important aspect in the quality-of-life of women and their reproductive health as well as a significant issue in public, environmental and social problems. Conclusions: It is very important to deal with it on the primary care level and in addition to promote the primary and secondary prevention of diseases, which is sometimes more important than the curative procedures. The primary prevention involves regular gynecological examinations and screening. The doctors have also a duty to educate women about the risk factors for malignant diseases, as well as proposing some of the qualitative preventive measures.
