    Civil defence forms part of the national defence of the G.D.R., and belongs since 1976 to the responsibility of the Defence Ministry. Civil defence service is equal to military service. Civil defence services are organised on a territorial basis and a production-oriented basis: Double concept. Construction of shelters is propagated for 30 years now, maintenance of existing buildings is an obligation since 1965. Principles (triage) of military medical service are applied, and are valid for students and post-graduate medical training. Civil defence training is required in school and industry. Civil defence expenditure is increasing, although there is little acceptance by the population. The issue presents extensive documentation. - Civil defence in the Soviet Union covers services in times of peace and of war. Defence measures are prepared and held up to date in the entire territory. The civil defence service belongs to the responsibility of the Council of Ministers, and the deputy minister of defence is the head of services. The training schedules and principles are laid down by the Central Committee of the Communist Party, the government, and local party organisations and governmental authorities. Civil defence training is a general obligation for all citizens over 8 years of age. The main goal is: Protection of the population as the production force, of the economy, and resources. (orig.)

    This article reports a combined suicide pact, where in a young couple; a 26 year old male and a 20 year old female committed suicide by using two methods. The couple had resorted to hanging and self-immolation to prevent failure of single method alone. In secondary combined suicides, several other methods of suicide are tried after the first method chosen has failed. It is primary combined suicide only when two or more methods are used simultaneously. Both types of combined suicide by one individual is well reported in the literature whereas the same by two persons together is rare. In this report, the deceased were disappointed lovers, poor and the family members were against their marriage. The investigation of scene, methods employed to commit suicide, autopsy findings and the interview with their relatives altogether suggested that it was a secondary combined suicide pact.

    Full Text Available Pact for Stability and Growth was to be a reliable way to ensure public finances. It commits the Economic Union countries to presenting a monetary budget in the medium term. The idea is to achieve a situation close to a balance in the budget, even a surplus. The deterioration of the fiscal situation of the European Union countries, including the euro area countries, especially in recent times, forcing the introduction of changes to the existing rules of the Pact. Undoubtedly, the introduction of the changes proposed by the European Commission should impact positively on the change in the approach to the problems of excessive deficits and public debt to GDP for the euro area, as well as for the future members of this zone in connection with ongoing processes of European integration.

    In the wake of the collapse of the Warsaw Pact and the apparent ending of the Cold War, there have been renewed calls for radical cuts in US strategic forces to levels far below the 10,000 or so warheads allowed each side under the current START proposal. Since it now appears that NATO for the first time will have the capability to defeat a Soviet conventional attack without the necessity of threatening to resort to nuclear weapons, this should pave the way for the rethinking of US strategy and the reduction of US strategic weapons requirements. In this new environment, it seems plausible that, with a modification of the Flexible Response doctrine to forego attempts to disarm the Soviet Union, deterrence could be maintained with 1500 or so survivable strategic weapons. With a new strategy that confined US strategic weapons to the role of deterring the use of nuclear weapons by other countries, a survivable force of about 500 weapons would seem sufficient. With this premise, the implications for the US strategic force structure are examined for two cases: a treaty that allows each side 3000 warheads and one that allows each side 1000 warheads. In Part 1 of this paper, the weapons requirements for deterrence are examined in light of recent changes in the geopolitical environment. In Part 2, it is assumed that the President and Congress have decided that deep cuts in strategic forces are acceptable. 128 refs., 12 figs., 12 tabs. (JF)

    We show analytically that the credibility problem which has affected the European Stability Pact originates from the insufficient distinction between two reasons for having binding fiscal constraints. The first reason deals with the governments’ tendency to neglect the effects of their fiscal policy on foreign governments (fiscal free-riding). The second reason follows from the governments’ tendency to raise debt by lowering taxes or increasing expenditures, and then to leave it to their succ...

    To fully understand how loads and turbine cost scale with turbine size, it is necessary to have identical turbine models that have been scaled to different rated powers. The report presents the WindPACT baseline models, which are a series of four baseline models that were designed to facilitate investigations into the scalings of loads and turbine cost with size. The models have four different rated powers (750 kW, 1.5 MW, 3.0 MW, and 5.0 MW), and each model was designed to its specified rated power using the same design methodology. The models were originally implemented in FAST_AD, the predecessor to NREL's open-source wind turbine simulator FAST, but have yet to be implemented in FAST. This report contains the specifications for all four WindPACT baseline models - including structural, aerodynamic, and control specifications - along with the inherent assumptions and equations that were used to calculate the model parameters. It is hoped that these baseline models will serve as extremely useful resources for investigations into the scalings of costs, loads, or optimization routines.

    Did the demise of the Soviet Union in 1991 influence the scientific performance of the researchers in Eastern European countries? Did this historical event affect international collaboration by researchers from the Eastern European countries with those of Western countries? Did it also change international collaboration among researchers from the Eastern European countries? Trying to answer these questions, this study aims to shed light on international collaboration by researchers from the Eastern European countries (Russia, Ukraine, Belarus, Moldova, Bulgaria, the Czech Republic, Hungary, Poland, Romania, and Slovakia). The number of publications and normalized citation impact values are compared for these countries based on InCites (Thomson Reuters), from 1981 up to 2011. The international collaboration by researchers affiliated to institutions in Eastern European countries at the time points of 1990, 2000 and 2011 was studied with the help of Pajek and VOSviewer software, based on data from the Science Citation Index (Thomson Reuters). Our results show that the breakdown of the communist regime did not lead, on average, to a huge improvement in the publication performance of the Eastern European countries and that the increase in international co-authorship relations by the researchers affiliated to institutions in these countries was smaller than expected. Most of the Eastern European countries are still subject to changes and are still awaiting their boost in scientific development.

    Programme of Action for Cancer Therapy (PACT) is the IAEA's response to the cancer challenge in developing countries. The long-term objective of PACT is Sustainable National Capacity for Cancer Care. The vision of PACT is to (a) build sustainable national cancer care infrastructure and capacity towards eventual self-sufficiency through South-South and North-South partnerships, (b) systematically plan and build capacity to diagnose and treat all patients with radiosensitive cancers, (c) focus on eliminating all cancer morbidity and mortality from unmet treatment needs among patients for whom radiotherapy is most effective and (d) deploy consistent and predictable resources and processes including investments from private donors to meet these objectives over a 5 to 10 year strategy. After the IAEA Board approval in 2004 the PACT office established early 2005. Engaged substantial steps followed to strategize and operationlise PACT. Public awareness campaign was initiated trough the public service announcements, web site development and national outreach seminars. Engagement with WHO, IARC, PAHO, ACS and others followed. The WHA resolution in May 2005 welcomes PACT and asks for a possible joint WHO-IAEA programme. PACT is being operationalised using specific mechanisms such as 'imPACT' (integrated missions of PACT). The 'imPACT' review will assist governments to review, analyse and formulate National Cancer Strategies and Action Plans for capacity building from prevention through palliation. It will also enable institutions to build and develop human resources and plans for capacity in radiation and nuclear oncology. The results of 'imPACT' will enable governments to work with partners, focus on centres of competence/reference to deliver quality cancer care, raise public awareness of cancer prevention, diagnosis and therapy and apply best practices, expand and continue professional development. The expected outcome will be integrated national strategies, action plans

  7. Bohdan Wodiczko’s Programming Policies at Warsaw Philharmonic (1955-1958. Toward the Warsaw Autumn.

    Directory of Open Access Journals (Sweden)

    Klubiński Michał

    2017-12-01

    Full Text Available As the managing and artistic director of Warsaw Philharmonic in 1955-58, Bohdan Wodiczko introduced an innovative programming policy which re-oriented the Philharmonic’s repertoire toward 20th-century classics and focused on the links between new music and that of other historical periods. The aim was to create a vast sonosphere of a “musical inter-age” (S. Kisielewski after M. Wańkowicz encompassing radically different styles and genres and significantly transforming the axiology of the musical art. Wodiczko’s novel programming, though largely concentrating on the already waning neo-Classicism, laid the foundations for the phenomenon of the Warsaw Autumn and was a harbinger of the political-cultural thaw that would come after October 1956. This paper examines Wodiczko’s programming revolution in its political context, as well as the critical reception of Warsaw Philharmonic concerts, with particular emphasis on the aesthetic disputes arising around those composers whose works provoked the greatest controversies: Igor Stravinsky and Carl Orff.

  8. 10 GHz ECRIS for Warsaw Cyclotron

    CERN Document Server

    Sudlitz, K

    1999-01-01

    Cusp type, 10 GHz ECRIS has been built and tested earlier. For obtaining intensive beams, more relevant for cyclotron, cusp geometry has been replaced by hexapole. Discharge chamber (stainless steel, 50 mm diameter, 250 mm long) is an extension of a coaxial line, feeding RF (9,6 GHz, up to 200 W) to the plasma. The NdFeB hexapole (0,52 T on the surface) has been used. The axial magnetic field is created by water cooled coils. The axial injection line dedicated to K160 isochronous heavy ion cyclotron has been constructed. The line consists of Glaser lenses, double focusing magnet, solenoid and mirror type inflector. The system provides sufficient transmission of the beam from ECR ion source to the firsts orbits of the cyclotron for m/q ranging from 7 to 2. After successful initial tests which were done in July 1997 the ECRIS serves as an external source for Warsaw Cyclotron.

  9. Contribution of Warsaw Logicians to Computational Logic

    Directory of Open Access Journals (Sweden)

    Damian Niwiński

    2016-06-01

    Full Text Available The newly emerging branch of research of Computer Science received encouragement from the successors of the Warsaw mathematical school: Kuratowski, Mazur, Mostowski, Grzegorczyk, and Rasiowa. Rasiowa realized very early that the spectrum of computer programs should be incorporated into the realm of mathematical logic in order to make a rigorous treatment of program correctness. This gave rise to the concept of algorithmic logic developed since the 1970s by Rasiowa, Salwicki, Mirkowska, and their followers. Together with Pratt’s dynamic logic, algorithmic logic evolved into a mainstream branch of research: logic of programs. In the late 1980s, Warsaw logicians Tiuryn and Urzyczyn categorized various logics of programs, depending on the class of programs involved. Quite unexpectedly, they discovered that some persistent open questions about the expressive power of logics are equivalent to famous open problems in complexity theory. This, along with parallel discoveries by Harel, Immerman and Vardi, contributed to the creation of an important area of theoretical computer science: descriptive complexity. By that time, the modal μ-calculus was recognized as a sort of a universal logic of programs. The mid 1990s saw a landmark result by Walukiewicz, who showed completeness of a natural axiomatization for the μ-calculus proposed by Kozen. The difficult proof of this result, based on automata theory, opened a path to further investigations. Later, Bojanczyk opened a new chapter by introducing an unboundedness quantifier, which allowed for expressing some quantitative properties of programs. Yet another topic, linking the past with the future, is the subject of automata founded in the Fraenkel-Mostowski set theory. The studies on intuitionism found their continuation in the studies of Curry-Howard isomorphism. ukasiewicz’s landmark idea of many-valued logic found its continuation in various approaches to incompleteness and uncertainty.

    Full Text Available This article discusses current crisis of the contemporary Spanish political system. Both of authors suppose, previously made pragmatic decisions aimed to consolidate Spanish society after the era of Franco had become effective only in short-term perspective and are limited to only short-term positive effect today. Contemporary Spanish society faces a problem of political renewal – both in terms of party-political structure and in terms of the constitutional and legal basis of the whole system. Authors present a complex definition of the crisis as a phenomenon of political life and discuss the concept of the political stability in terms of actual practice conditions – including the realities of Spanish society. Various components of contemporary Spanish instability (the parties’ crisis, the lack of a strategic economic vector, the problems of identity and regional policy strictly connects to the sharp conservative belief of political actors in the constitutional grounds of the Spanish state and the Moncloa Pact behind these base.

    This work investigates X-PACT (X-ray Psoralen Activated Cancer Therapy): a new approach for the treatment of solid cancer. X-PACT utilizes psoralen, a potent anti-cancer therapeutic with current application to proliferative disease and extracorporeal photopheresis (ECP) of cutaneous T Cell Lymphoma. An immunogenic role for light-activated psoralen has been reported, contributing to long-term clinical responses. Psoralen therapies have to-date been limited to superficial or extracorporeal scenarios due to the requirement for psoralen activation by UVA light, which has limited penetration in tissue. X-PACT solves this challenge by activating psoralen with UV light emitted from novel non-tethered phosphors (co-incubated with psoralen) that absorb x-rays and re-radiate (phosphoresce) at UV wavelengths. The efficacy of X-PACT was evaluated in both in-vitro and in-vivo settings. In-vitro studies utilized breast (4T1), glioma (CT2A) and sarcoma (KP-B) cell lines. Cells were exposed to X-PACT treatments where the concentrations of drug (psoralen and phosphor) and radiation parameters (energy, dose, and dose rate) were varied. Efficacy was evaluated primarily using flow cell cytometry in combination with complimentary assays, and the in-vivo mouse study. In an in-vitro study, we show that X-PACT induces significant tumor cell apoptosis and cytotoxicity, unlike psoralen or phosphor alone (pphosphor, psoralen, or radiation increase. Finally, in an in-vivo pilot study of BALBc mice with syngeneic 4T1 tumors, we show that the rate of tumor growth is slower with X-PACT than with saline or AMT + X-ray (p<0.0001). Overall these studies demonstrate a potential therapeutic effect for X-PACT, and provide a foundation and rationale for future studies. In summary, X-PACT represents a novel treatment approach in which well-tolerated low doses of x-ray radiation are delivered to a specific tumor site to generate UVA light which in-turn unleashes both short- and potentially long

  14. Evaluation of the importance of employment pacts and the case study - Moravian-Silesian employment pact in the Czech Republic

    Directory of Open Access Journals (Sweden)

    MSc. Šárká Prudká

    2012-12-01

    Full Text Available This paper is focused on the evaluation of the effectiveness of a tool that is used in the world and Europe to a comprehensive and systematic solution of the employment at the regional level. These are the so-called employment pacts. The theme is the more up-to-date due to the onset of the global economic crisis since 2008, which brought a deepening of socio-economic problems in the labour market, with negative implications upon an increasing rate of unemployment. The Moravian-Silesian Employment Pact has been chosen for the case study. It was established as the first one of its kind in the Czech Republic, in the structurally affected region of Silesia. The result is the finding that employment pacts are generally a useful tool to resolve problems in regional labor markets.

  15. Airport Catchment Area- Example Warsaw Modlin Airport

    Science.gov (United States)

    Błachut, Jakub

    2017-10-01

    The form and functions of airports change over time, just like the form and function of cities. Historically, airports are understood as places of aircraft landing, control towers operation and location of other facilities used for communication and transport. This traditional model is giving way to the concept of so-called Airport Cities, based on the assumption that, in addition to its infrastructure and air services, also non-air services are performed, constituting a source of income. At the same time, their reach and impact on the economy of the areas around the airport are expanding. Idea City Airport appeared in the United States in the late twentieth century. The author is J. D. Kasarda, he believes that it is around these big air ports that airport cities develop. In the world, there are currently 45 areas which can be classified in this category, out of which 12 are located in Europe. Main air traffic hubs in Europe are not only the most important passenger traffic junctions, but also largest centres dispatching goods (cargo). It can be said that, among the 30 largest airports, 24 are the largest in terms of both passenger and freight traffic. These airports cover up to 89.9% of the total freight transport of all European airports. At the same time, they serve 56.9% of all passengers in Europe. Based on the concept of Airport City was developed document THE INTEGRATED REGIONAL POLYCENTRIC DEVELOPMENT PLANS FOR THE WARSAW MODLIN AIRPORT CATCHMENT AREA. The plan developed takes into account the findings of the Mazovian voivodeship spatial development plan, specifying the details of its provisions where possible. The development is the first step for the implementation of the concept of the Modlin Airport City. The accomplishment of this ambitious vision will only be possible with hard work of a number of entities, as well as taking into account the former Modlin Fortress, currently under revitalisation, in concepts and plans.

  16. Pollution added credit trading (PACT). New dimensions in emissions trading

    International Nuclear Information System (INIS)

    Schaltegger, Stefan; Thomas, Tom

    1996-01-01

    To date, sources of hazardous, toxic, or otherwise harmful emissions have been regulated on a pollutant by pollutant basis. Environmental policies, even the more advanced 'incentive-based' programs, have focused on individual substances rather than on the overall environmental problem to which the substances contribute. This has produced results that are less economically efficient and ecologically effective than is desirable. A more comprehensive approach combines the principles of emission reduction credit trading with advances made recently in the field of environmental impact assessment, to yield an advanced form of inter-pollutant trading, which we refer to as pollution added credit trading (PACT). PACT incorporates a method for estimating the total environmental harm generated (pollution added) by a facility emitting a variety of pollutants. Weightings that reflect relative harm are used to calculate total pollution added. Each facility covered by PACT would receive annual allowances for total pollution added that they could discharge to the environment. As with existing emissions trading programs, surplus allowances could be sold and shortfalls would be covered by purchasing other facilities' surplus allowances. PACT is more efficient than single-pollutant emissions trading in that it captures differences in marginal reduction costs that exist between pollutants as well as between facilities. It is more ecologically effective because it focuses on the overall environmental problem, rather than on the individual pollutants that contribute to the problem

    2010-06-01

    Welzijnsorganisaties, onderzoekinstellingen, overheidsinstellingen en woningcorporaties zijn alle potentiële partners in stedelijke herstructureringsprogramma’s. Het combineren van de belangen van deze organisaties vormt een interessante managementuitdaging. Ook is het een uitdaging om een informatiesysteem te ontwikkelen dat tegemoet komt aan de informatiebehoefte van alle partners, zowel de afzonderlijke organisaties, als het collectief. Dit artikel zal deze uitdaging van informatiemanagement bespreken, door een case study naar cooperative knowledge production te presenteren. De case study heeft betrekking op het Rotterdamse stedelijk investeringssprogramma “Pact op Zuid”, een programma waarin tussen 2006 en 2016 1.5 miljard euro wordt geïnvesteerd in stedelijk gebied met 190.000 inwoners. Dit artikel geeft allereerst inzicht in literatuur over innovatieconfiguraties en lerende netwerken, concepten die belangrijk zijn om de complexiteit van stedelijke renovatie en cooperative knowledge production te begrijpen. Het bespreekt eveneens hoe cooperative knowledge production binnen Pact op Zuid plaatsvond.

    Full Text Available This working paper seeks to define perspectives of the functioning of the Stability and Growth Pact as a tool for regulation of national fiscal policies through analysis and description of legal acts regarding the Pact and through analysis and statistical evaluation of the compliance of the EMU States with requirements for fiscal discipline. The first part brings the description of the Pact's functioning mechanism and defines its weaknesses (e.g. extensive role of the Council. The second part tries to analyse and statistically evaluate how the Member States complied with the provisions of the Pact during the years 1999-2003. The results are compared with the most mentioned shortcomings of the Pact. In the concluding part the paper discusses proposals for a change of the Pact and tries to estimate perspectives of its functioning in the future.

    Full Text Available The authors argue through this paper, the importance of rethinking the recently abandoned tools that can be reactivated in times of crisis. EU 2020 Strategy and other EU documents create a favorable frame in order to achieve the priorities set by reconsidering the territorial pact concept. Recent documents define the partnership agreement concept, which seems to be more rigid and less flexible than the territorial pact. Having as a starter point Romania’s specifics, there are individualized 10 thematic territorial pacts and 8 global pacts. They must generate territorial synergies capable of ensuring the coherence between regions, states and the European Union as a whole.

  4. The Warsaw Autumn International Festival of Contemporary Music Transformations of Programming Policies

    Directory of Open Access Journals (Sweden)

    Gąsiorowska Małgorzata

    2017-12-01

    Full Text Available The present paper surveys the history of the Warsaw Autumn festival focusing on changes in the Festival programming. I discuss the circumstances of organising a cyclic contemporary music festival of international status in Poland. I point out the relations between programming policies and the current political situation, which in the early years of the Festival forced organisers to maintain balance between Western and Soviet music as well as the music from the so-called “people’s democracies” (i.e. the Soviet bloc. Initial strong emphasis on the presentation of 20th-century classics was gradually replaced by an attempt to reflect different tendencies and new phenomena, also those combining music with other arts. Despite changes and adjustments in the programming policy, the central aim of the Festival’s founders – that of presenting contemporary music in all its diversity, without overdue emphasis on any particular trend – has consistently been pursued. The idea of introducing leitmotifs, different for each Festival edition (such as: music involving human voice, mainly electronic, etc. – is not inconsistent with this general aim since the selected works represent different aesthetics, and the “main theme” is not the only topic of any given edition of the Warsaw Autumn.

    2012-06-01

    Full Text Available The following paper aims to assess investor reaction to mandatory offers on the Warsaw Stock Exchange, which is important because knowledge about these reactions can be used to make better investment decisions. This paper highlights the importance of procedure in making a mandatory offer and its grounds in the Polish legal system. Additionally, it presents empirical research on the reactions of investors to mandatory offers on the Warsaw Stock Exchange. It has been provided that mandatory offers have a significant impact on the price of a company’s shares listed on the Warsaw Stock Exchange. Knowledge about the reactions of investors to a mandatory offer may be used when selecting securities for an investment portfolio. The findings may provide guidance in deciding whether to begin or end investment in the company, both for individual and institutional investors. The event study methodology approach used in the paper is regarded as valuable and can be the basis for further research in other areas of the capital market research, especially in the context of information efficiency.

    2016-02-01

    The goals of the study included empirical examination of the utility of the Immediate and Post-Concussion Assessment and Cognitive Testing (ImPACT) test with adolescents who are deaf or hard-of-hearing and to investigate patterns of performance at baseline that may arise in the assessment of this population. Baseline assessment of student-athletes has been conducted on a widespread scale with focus on performance of typically developing student-athletes and some clinical groups, though to date no studies have examined adolescents who are deaf or hard-of-hearing. Retrospective and de-identified ImPACT baseline test used with deaf and hard-of-hearing high-school student-athletes (N = 143; 66% male, mean age = 16.11) was examined. Review indicated significant differences in some composite scores between the deaf and hard-of-hearing group and hearing normative comparisons. A possible marker of task misunderstanding was identified to occur more frequently within the deaf and hard-of-hearing sample (13% in deaf sample vs. .31% in hearing sample). Results may provide support for the consideration and use of additional measures to ensure comprehension of task demands when considering this tool for use with deaf and hard-of-hearing adolescents.

    2018-06-01

    To examine how Twitter is used as a place where people seek others to make suicide pacts. This is an exploratory quantitative study. We used Twitter application programming interfaces to collect all Korean tweets containing the term 'suicide pact' between October 16, 2017 and November 30, 2017. A Python program and human coders were employed to further identify tweets that aimed to seek others to make a suicide pact and analyze the content of each tweet. Poisson regression analysis was used to examine the characteristics of the tweets that attracted more replies. During the data collection period comprising 43 days, 1702 tweets posted by 551 users were aimed to find others to make suicide pacts. Many of the tweets contained detailed information such as the name of city, gender and age of the user, preferred contact method, and preferred gender of a partner. The number of replies to a tweet seeking a suicide pact varied according to the types of the information contained in the tweet. The results of this study indicate that Twitter might be an attractive place where people try to meet others to make a suicide pact. Thus, the government should try to prevent cases of suicides caused by suicide pacts made via Twitter. Copyright © 2018 The Royal Society for Public Health. Published by Elsevier Ltd.

    The PACTES project (Prévention et Anticipation des Crues au moyen des Techniques Spatiales), initiated by CNES and the French Ministry of Research, aims at improving flood risk management, over the following three main phases : - Prevention : support and facilitate the analysis of flood risks and socio-economic impacts (risk - Forecasting and alert : improve the capability to predict and anticipate the flooding event - Crisis management : allow better situation awareness, communication and sharing of In order to achieve its ambitious objectives, PACTES: - integrates state-of-the-art techniques and systems (integration of the overall processing chains, - takes advantage of integrating recent model developments in wheather forecasting, rainfall, In this approach, space technology is thus used in three main ways : - radar and optical earth observation data are used to produce Digital Elevation Maps, land use - earth observation data are also an input to wheather forecasting, together with ground sensors; - satellite-based telecommunication and mobile positioning. Started in December 2000, the approach taken in PACTES is to work closely with users such as civil security and civil protection organisms, fire fighter brigades and city councils for requirements gathering and during the validation phase. It has lead to the development and experimentation of an integrated pre-operational demonstrator, delivered to different types of operational users. Experimentation has taken place in three watersheds representative of different types of floods (flash and plain floods). After a breaf reminder of what the PACTES project organization and aims are, the PACTES integrated pre-operational demonstrator is presented. The main scientific inputs to flood risk management are summarized. Validation studies for the three watersheds covered by PACTES (Moselle, Hérault and Thoré) are detailed.

    PACT is a space borne Pair and Compton Telescope that aims to make a sensitive survey of the gamma-ray sky between 100 keV and 100 MeV. It is based upon two main components: a silicon-based gamma-ray tracker and a crystal-based calorimeter. In this paper we will explain the imaging technique of PACT as a Multi-layered Compton telescope (0.1-10 MeV) and its major improvements over its predecessor COMPTEL. Then we will present a simulation study to optimize the silicon tracker of PACT. This tracker is formed of thousands of identical silicon double sided strip detectors (DSSDs). We have developed a simulation model (using SILVACO) to simulate the DSSD performance while varying its thickness, impurity concentration of the bulk material, electrode pitch, and electrode width. We will present a comprehensive overview of the impact of each varied parameter on the DSSD performance, in view of the application to PACT. The considered DSSD parameters are its depletion voltage, capacitance, and leakage current. After the selection of the PACT DSSD, we will present a simulation of the performance of the PACT telescope in the 0.1-10 MeV range.

    2017-09-01

    Water vapor mixing ratio and relative humidity profiles were derived from the multi-wavelength Raman PollyXT lidar at the EARLINET site in Warsaw, using the Rayleigh molecular extinction calculation based on atmospheric temperature and pressure from three different sources: i) the standard atmosphere US 62, ii) the Global Data Assimilation System (GDAS) model output, and iii) the WMO 12374 radiosoundings launched at Legionowo. With each method, 136 midnight relative humidity profiles were obtained for lidar observations from July 2013 to August 2015. Comparisons of these profiles showed in favor of the latter method (iii), but it also indicated that the other two data sources could replace it, if necessary. Such use was demonstrated for an automated retrieval of water vapor mixing ratio from dusk until dawn on 19/20 March 2015; a case study related to an advection of biomass burning aerosol from forest fires over Ukraine. Additionally, an algorithm that applies thresholds to the radiosounding relative humidity profiles to estimate macro-physical cloud vertical structure was used for the first time on the Raman lidar relative humidity profiles. The results, based on a subset of 66 profiles, indicate that below 6 km cloud bases/tops can be successfully obtained in 53% and 76% cases from lidar and radiosounding profiles, respectively. Finally, a contribution of the lidar derived mean relative humidity to cloudy conditions within the range of 0.8 to 6.2 km, in comparison to clear-sky conditions, was estimated.

  7. Measuring cognitive change with ImPACT: the aggregate baseline approach.

    2017-11-01

    The Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) is commonly used to assess baseline and post-injury cognition among athletes in North America. Despite this, several studies have questioned the reliability of ImPACT when given at intervals employed in clinical practice. Poor test-retest reliability reduces test sensitivity to cognitive decline, increasing the likelihood that concussed athletes will be returned to play prematurely. We recently showed that the reliability of ImPACT can be increased when using a new composite structure and the aggregate of two baselines to predict subsequent performance. The purpose of the present study was to confirm our previous findings and determine whether the addition of a third baseline would further increase the test-retest reliability of ImPACT. Data from 97 English speaking professional hockey players who had received at least 4 ImPACT baseline evaluations were extracted from a National Hockey League Concussion Program database. Linear regression was used to determine whether each of the first three testing sessions accounted for unique variance in the fourth testing session. Results confirmed that the aggregate baseline approach improves the psychometric properties of ImPACT, with most indices demonstrating adequate or better test-retest reliability for clinical use. The aggregate baseline approach provides a modest clinical benefit when recent baselines are available - and a more substantial benefit when compared to approaches that obtain baseline measures only once during the course of a multi-year playing career. Pending confirmation in diverse samples, neuropsychologists are encouraged to use the aggregate baseline approach to best quantify cognitive change following sports concussion.

    Full Text Available Background. Intestinal parasitic infestations pose one of the biggest health problems of the contemporary world. Objectives. The aim of this article was to present the prevalence of intestinal parasites among children living in a large urban agglomeration. Material and methods . 1823 children (916 girls and 907 boys, aged 3–6, attending 31 different pre-schools in Warsaw, were examined in 2014. Stool specimens were tested in the Department of Epidemiology and Tropical Medicine of the Military Institute of Medicine by light microscopy using three different diagnostic methods (direct smear in Lugol’s solution, decantation with distilled water, Fülleborn’s flotation. The material for testing, fixed in 10% formalin, was collected three times at 2–3-day intervals. Results . Parasitological examination of the stool specimens showed intestinal parasitic infestations in 47 children (2.57% of the study group. Only 7 children were infested with pathogenic parasites (6 cases of giardiasis and 1 enterobiasis and required antiparasitic treatment. 17 children were infested with potentially pathogenic protozoa (Blasocystis sp. and 26 with non-pathogenic protozoa ( Entamoeba coli , Endolimax nanai , but because of lack of gastrointestinal symptoms (asymptomatic carriage they did not require a treatment. Conclusions . Performed examination show low infection rates among children from a large urban agglomeration. In the absence of epidemiological surveillance over the prevalence of the majority of intestinal parasitic diseases in Poland, and because some diagnostic centres generate positive test results using valueless methods, the propagation of parasitological diagnostics in light microscopy in direction of prevalence of intestinal parasitic infestations, especially among patients with gastrointestinal symptoms, is strongly recommended.

    Self-rated health is a one-point measure commonly used for recognising subjectively perceived health and covering a wide range of individual's health aspects. The aim of our study was to examine the extent to which self-rated health reflects the differences due to demographic characteristics, physical, psychical and social well-being, health disorders, occurrence of chronic disease and negative life events in Polish social and cultural conditions. Data were collected by non-addressed questionnaire methods from 402 Warsaw inhabitants. The questionnaire contained the questions concerning self-rated health, physical, psychical and social well-being, the use of health care services, occurrence of chronic disease and contact with negative life events. The analysis showed that worse self-rated health increased exponentially with age and less sharply with lower level of education. Pensioners were more likely to assess their own health worse then employed or students. Such difference was not found for unemployed. Compared to married, the self-rated health of divorced or widowed respondents was lower. Gender does not differentiate self-rated health. In regard to well-being, self-rated health linearly decreased for physical well-being, for social and, especially, for psychical well-being the differences were significant, but more complicated. Hospitalisation, especially repeated, strongly determined worse self-rated health. In contrast, relationship between self-rated health and sickness absence or frequency of contact with physician were lower. Chronic diseases substantially increased the risk of poorer self-rated health, and their co-morbidity increased the risk exponentially. The patients with cancer were the group, in which the risk several times exceeded that reported for the patients of other diseases. Regarding negative life events, only experience with violence and financial difficulties were resulted in worse self-rated health. Our findings confirmed the usefulness

    Following the implementation of the National Cancer Prevention and Control Results-based Budget Programme (PpR Cancer-024) in 2011, the Peruvian Government approved the Plan Esperanza-a population-based national cancer control plan-in 2012. Legislation that ensured full government-supported funding for people who were otherwise unable to access or afford care and treatment accompanied the Plan. In 2013, the Ministry of Health requested an integrated mission of the Programme of Action for Cancer Therapy (imPACT) report to strengthen cancer control in Peru. The imPACT Review, which was executed in 2014, assessed Peru's achievements in cancer control, and areas for improvement, including cancer control planning, further development of population-based cancer registration, increased prevention, early diagnosis, treatment and palliative care, and the engagement and participation of civil society in the health-care system. This Series paper gives a brief history of the development of the Plan Esperanza, describes the innovative funding model that supports it, and summarises how funds are disseminated on the basis of disease, geography, and demographics. An overview of the imPACT Review, and the government's response in the context of the Plan Esperanza, is provided. The development and execution of the Plan Esperanza and the execution of and response to the imPACT Review demonstrates the Peruvian Government's commitment to fighting cancer across the country, including in remote and urban areas.

    The main cause of morbidity and mortality in cystic fibrosis (CF) sufferers is progressive pulmonary damage caused by recurrent and often unremitting respiratory tract infection. Causative organisms include Pseudomonas aeruginosa and Haemophilus influenzae, but in recent years the Burkholderia cepacia complex has come to the fore. This group of highly drug-resistant Gram-negative bacteria are associated with a rapid decline in lung function and the often fatal cepacia syndrome, with treatment limited to patient segregation and marginally effective antibacterial regimens. Thus, development of an effective treatment is of the upmost importance. PACT, a non-target specific therapy, has proven successful in killing both Gram-positive and Gram-negative bacteria. In this study, planktonic cultures of six strains of the B. cepacia complex were irradiated (635 nm, 200 J cm-2,10 minutes irradiation) following 30 seconds incubation with methylene blue (MB) or meso-tetra (N-methyl-4-pyridyl) porphine tetra tosylate (TMP). Rates of kill of > 99 % were achieved with MB- and TMP-PACT. A MB concentration of 50 μg ml-1 and TMP concentration of 500 μg ml-1 were associated with highest percentage kills for each photosensitizer. PACT is an attractive option for treatment of B.cepacia complex infection. Further study, involving biofilm culture susceptibility, delivery of light to the target and in vivo testing will be necessary before it PACT becomes a viable treatment option for CF patients who are colonised or infected with B. cepacia complex.

    Full Text Available Abstract Background The 'Perception of Anti-Coagulant Treatment Questionnaire' (PACT-Q was developed to assess patients' expectations of, and satisfaction with their anticoagulant treatment. This questionnaire needs to be finalised and psychometrically validated. Methods The PACT-Q was included in the United States, the Netherlands and France into three phase III multinational clinical trials conducted to evaluate efficacy and safety of a new long-acting anticoagulant drug (idraparinux compared to vitamin K antagonist (VKA. PACT-Q was administered to patients with deep venous thrombosis (DVT, atrial fibrillation (AF or pulmonary embolism (PE at Day 1, to assess patients' expectations, and at 3 and 6 months to assess patients' satisfaction and treatment convenience and burden. The final structure of the PACT-Q (Principal Component Analysis – PCA – with Varimax Rotation was first determined and its psychometric properties were then measured with validity of the structure (Multitrait analysis, internal consistency reliability (Cronbach's alpha coefficients and known-group validity. Results PCA and multitrait analyses showed the multidimensionality of the "Treatment Expectations" dimension, comprising 7 items that had to be scored independently. The "Convenience" and "Burden of Disease and Treatment" dimensions of the hypothesised original structure of the questionnaire were combined, thus resulting in 13 items grouped into the single dimension "Convenience". The "Anticoagulant Treatment Satisfaction" dimension remained unchanged and included 7 items. All items of the "Convenience" and "Anticoagulant Treatment Satisfaction" dimensions displayed good convergent and discriminant validity. The internal consistency reliability was good, with a Cronbach's alpha of 0.84 for the "Convenience" dimension, and 0.76 for the "Anticoagulant Treatment Satisfaction" dimension. Known-group validity was good, especially with regard to occurrence of

    The cytoplasmic pattern recognition receptor RIG-I is activated by viral RNA and induces type I IFN responses to control viral replication. The cellular dsRNA binding protein PACT can also activate RIG-I. To counteract innate antiviral responses, some viruses, including Ebola virus (EBOV), encode proteins that antagonize RIG-I signaling. Here, we show that EBOV VP35 inhibits PACT-induced RIG-I ATPase activity in a dose-dependent manner. The interaction of PACT with RIG-I is disrupted by wild-type VP35, but not by VP35 mutants that are unable to bind PACT. In addition, PACT-VP35 interaction impairs the association between VP35 and the viral polymerase, thereby diminishing viral RNA synthesis and modulating EBOV replication. PACT-deficient cells are defective in IFN induction and are insensitive to VP35 function. These data support a model in which the VP35-PACT interaction is mutually antagonistic and plays a fundamental role in determining the outcome of EBOV infection. Copyright © 2013 Elsevier Inc.

    To automate astronaut organ and effective dose calculations from occupational X-ray and computed tomography (CT) examinations incorporating PCXMC and ImPACT tools and to estimate the associated lifetime cancer risk per the National Council on Radiation Protection & Measurements (NCRP) using MATLAB(R). Methods: NASA follows guidance from the NCRP on its operational radiation safety program for astronauts. NCRP Report 142 recommends that astronauts be informed of the cancer risks from reported exposures to ionizing radiation from medical imaging. MATLAB(R) code was written to retrieve exam parameters for medical imaging procedures from a NASA database, calculate associated dose and risk, and return results to the database, using the Microsoft .NET Framework. This code interfaces with the PCXMC executable and emulates the ImPACT Excel spreadsheet to calculate organ doses from X-rays and CTs, respectively, eliminating the need to utilize the PCXMC graphical user interface (except for a few special cases) and the ImPACT spreadsheet. Results: Using MATLAB(R) code to interface with PCXMC and replicate ImPACT dose calculation allowed for rapid evaluation of multiple medical imaging exams. The user inputs the exam parameter data into the database and runs the code. Based on the imaging modality and input parameters, the organ doses are calculated. Output files are created for record, and organ doses, effective dose, and cancer risks associated with each exam are written to the database. Annual and post-flight exposure reports, which are used by the flight surgeon to brief the astronaut, are generated from the database. Conclusions: Automating PCXMC and ImPACT for evaluation of NASA astronaut medical imaging radiation procedures allowed for a traceable and rapid method for tracking projected cancer risks associated with over 12,000 exposures. This code will be used to evaluate future medical radiation exposures, and can easily be modified to accommodate changes to the risk

    Full Text Available This contribution investigates how the emergence of the first modern Jewish metropolis in Warsaw in the second half of the 19th century challenged traditional visions of community cohesion. It argues that the acceleration of political and societal change within the Jewish community allowed observant elites to achieve political and cultural hegemony in Warsaw, and thus offers a sui generis pathway of Jewish metropolitan modernization. This claim is substantiated by following the communal and political involvement of a leading Hasidic civil leader, Joel Wegmeister (1837-1919, co-founder of the first outlets of the Agudat Israel in the Kingdom of Poland before World War One

Os poucos trabalhos na literatura sobre pactos na saúde frequentemente os relacionam à consolidação dos princípios do SUS, especificamente à implantação da descentralização. Aqui são evidenciadas as raízes dessa política, mostrando-se como estão articuladas ao movimento de reestruturação do próprio Estado brasileiro, ocorrido nas últimas décadas do século XX, por meio da reconstrução da democracia, do federalismo e da Reforma do Estado. Neste período, são identificados avanços na democracia política, porém pouca evolução na consolidação da democracia social. Os pactos na saúde articulam-se aos pactos sociais e políticos, estes últimos essenciais para tornar possível a vida em sociedade, garantir a legitimidade dos governos, a governabilidade e a efetividade das políticas públicas. A pactuação é um mecanismo de gestão que compreende negociação permanente, buscando a superação dos conflitos intergovernamentais, pautada pela responsabilização solidária. Por meio da negociação de metas, indicadores e ações, os pactos se constituem numa forma de accountability e transparência, capaz de favorecer o controle social e o do próprio governo.The object of this article is the pact policy of the Unified Health System (SUS.

    The Programme of Action for Cancer Therapy (PACT) was created within the IAEA in 2004. PACT builds upon IAEA's extensive experience in cancer therapy and was designed to strengthen the links between technology transfer for radiotherapy and national capacity building in cancer prevention and control. While the IAEA continues to focus on technology transfer in radiotherapy and nuclear medicine, PACT is aimed at integrating radiotherapy into the broader cancer prevention and control framework. This includes cancer prevention, early detection, treatment and palliative care as well as broader challenges such as capacity building in infrastructure development and surveillance (including cancer registries). Only through collaboration with a broad range of stakeholders in cancer prevention and control will low and middle income countries be able to build effective programmes that reduce avoidable cancers and cancer in its later stages, and therefore improve survival and quality of life for cancer patients. PACT is therefore building partnerships with leading cancer organizations worldwide. Each organization is making a significant contribution in their respective areas of expertise within the broader cancer control framework. Outreach to more international organizations continues. Together with these other agencies, PACT seeks to comprehensively support cancer control needs in low and middle income countries over the next 10 to 20 years and beyond. PACT is seeking to accelerate widespread and sustained access to all essential cancer care services, and make cancer therapy more effective. Such an approach is widely acknowledged to be the only viable way to attract major donors (including development banks, international health philanthropies and other charities) either directly or through the IAEA. Partnering with other organizations also raises, or in many cases, establishes the IAEA's profile within the international public health arena. To lay the groundwork for

    Full Text Available In the aftermath of an increasing integration of property and financial markets, the real estate industry is subject to soaring internationalization processes. Since international institutional investors appeared, transnational real estate investments have increased tremendously. In recent years, Central and Eastern European countries have been becoming more attractive to institutional investors and are therefore being integrated into international market structures. Within these countries, Warsaw emerged as the most dynamic and important real estate market. But what are the mechanisms and practices through which the real estate market of Warsaw becomes international? Which networks, intermediaries and frames are necessary to constitute a mature real estate market? The article argues that international real estate consultants are playing a crucial role in the underlying internationalization process. They are acting at the interface between investors, developers, construction companies and tenants and are therefore becoming a crucial hinge between real estate actors. With the example of the Warsaw real estate market we argue that international real estate consultancies are key drivers of the transformation process from a local to a global market. They transfer global knowledge, competence and practices and implement transparent and professional structures in the emerging Warsaw real estate market.

    In 2010, the Preventable Admissions Care Team (PACT), a social work-led transitional care model, was developed at Mount Sinai to reduce 30-day readmissions among high-risk patients. PACT begins with a comprehensive bedside assessment to identify the psychosocial drivers of readmission. In partnership with the patient and family, a patient-centered action plan is developed and carried out through phone calls, accompaniments, navigations and home visits, as needed, in the first 30 days following discharge. 620 patients were enrolled during the pilot from September 2010-August 2012. Outcomes demonstrated a 43% reduction in inpatient utilization and a 54% reduction in emergency department visits among enrollees. In addition, 93% of patients had a follow-up appointment within 7-10 days of discharge and 90% of patients attended the appointment. The success of PACT has led to additional funding from the Centers for Medicare and Medicaid Services under the Community-based Care Transitions Program and several managed care companies seeking population health management interventions for high risk members.

  6. Radiation in industrial processes;Applications reviewed at Warsaw Conference

    1959-10-15

    The uses of ionizing radiation can be divided into two broad categories. First, it can be used as a tool of investigation, measurement and testing, and secondly, it can be a direct agent in inducing chemical processes. For example, radiation can help in the detecting and locating of malignant tumours, and it can be employed also for the destruction of those tumours. Again, it can reveal intricate processes of plant growth and, at the same time, can initiate certain processes which result in the growth of new varieties of plants. Similarly in industry, radiation is both a tool of detection, testing and measurement and an active agent for the initiation of useful chemical reactions. The initiation of chemical reactions usually requires larger and more powerful sources of radiation. Such radiation can be provided by substances like cobalt 60 and caesium 137 or by machines which accelerate nuclear particles to very high energies. Of the particle-accelerating machines, the most useful in this field are those which accelerate electrons to energies considerably higher than those possessed by the electrons (beta particles) emitted by radioactive substances. These high-energy radiations produce interesting reactions both in organic life and in materials for industry. Several of the papers presented at the Warsaw conference were devoted to the application of ionizing radiation to polymerization and other useful reactions in the manufacture and treatment of plastics. The polymerization of the ethylene series of hydro-carbons was discussed from various angles and the technical characteristics and requirements were described. It was pointed out by some experts that the cross-linking effect of radiation resulted in a superior product, opening the way to new applications of polyethylene. Irradiated polyethylene film has been sold for several years, and electrical wire has been made with irradiated polyethylene as the insulating jacket. Other reactions discussed included the cross

    Results of small trials suggest that early interventions for social communication are effective for the treatment of autism in children. We therefore investigated the efficacy of such an intervention in a larger trial. Children with core autism (aged 2 years to 4 years and 11 months) were randomly assigned in a one-to-one ratio to a parent-mediated communication-focused (Preschool Autism Communication Trial [PACT]) intervention or treatment as usual at three specialist centres in the UK. Those assigned to PACT were also given treatment as usual. Randomisation was by use of minimisation of probability in the marginal distribution of treatment centre, age (42 months), and autism severity (Autism Diagnostic Observation Schedule-Generic [ADOS-G] algorithm score 12-17 or 18-24). Primary outcome was severity of autism symptoms (a total score of social communication algorithm items from ADOS-G, higher score indicating greater severity) at 13 months. Complementary secondary outcomes were measures of parent-child interaction, child language, and adaptive functioning in school. Analysis was by intention to treat. This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN58133827. 152 children were recruited. 77 were assigned to PACT (London [n=26], Manchester [n=26], and Newcastle [n=25]); and 75 to treatment as usual (London [n=26], Manchester [n=26], and Newcastle [n=23]). At the 13-month endpoint, the severity of symptoms was reduced by 3.9 points (SD 4.7) on the ADOS-G algorithm in the group assigned to PACT, and 2.9 (3.9) in the group assigned to treatment as usual, representing a between-group effect size of -0.24 (95% CI -0.59 to 0.11), after adjustment for centre, sex, socioeconomic status, age, and verbal and non-verbal abilities. Treatment effect was positive for parental synchronous response to child (1.22, 0.85 to 1.59), child initiations with parent (0.41, 0.08 to 0.74), and for parent-child shared attention (0.33, -0.02 to

    Full Text Available This article aims to offer a broader understanding of the Lithuanian reception of the Warsaw Autumn festival in relation to the modernisation of national music in Lithuania since the late 1950s – early 1960s. Based on a micro-historical and comparative approach to the network of individuals and events, it is intended to explore the shifts of reception through analysis of musical criticism, composers’ work and discourse, and artistic exchange between the Lithuanian and Polish new music scenes. The author discusses the cultural and political factors which affected the changing role of the Warsaw Autumn festival and its impact on the modernisation processes in Lithuanian music. In addition, the asymmetries of mutual understanding and interests between the Polish and Lithuanian music cultures have been highlighted both during the Cold War and the post-communist transformation periods.

    The levels of 131 I were determined in the thyroids of 20 dogs from Warsaw submitted to euthanasia between May and September 1986. The animals were living with humans and were in similar way exposed to contamination after the Chernobyl reactor accident. After calculation of the radioactivity for May 10th the contamination was found to range from 142.9 to 1372.9 Bq. These values corresponded to the contamination of human thyroids as reported by Central Laboratory for Radiation Protection in Warsaw. From the begining of May to the end of November the number of operations performed in dogs for pathological thyroid hyperplasia was six times higher than in the preceding time period. 5 refs., 2 tabs.

    2011-01-01

    The local properties of the time series of the evolution of share prices of 126 significant companies traded on the Warsaw Stock Exchange during the period between 1991-2008 have been investigated. The analysis was applied to daily financial returns. I have used the local DFA to obtain the Hurst exponent (diffusion coefficient) while searching for negative correlations by which changes of long-term trends would be effected. A certain evidence, proving that after the signature of anti-correlation-the drop in the Hurst exponent-the change in the trend and in the return rate of an investment is probable, was pointed out. Hence after further investigation this method may be useful as a part of an investment strategy. As the Warsaw Stock Exchange is relatively smaller and younger than other significant world Stock Exchanges-and as the developing market is less efficient-the generalization for others markets needs further investigation.

    2007-01-01

    In this paper we provide an empirical analysis of announcements of resignation of board members using data which comes from the Warsaw Stock Exchange. The market reaction to this information is tested at different time horizons by means of event study methodology. The results show that market reaction is rather positive immediately before the announcement release and negative over the following six-day-period starting on the event day. A possible explanation for this phenomenon is suggested. ...

    This paper reports on the conventional wisdom which is that if Warsaw Pact forces attacked NATO they would probably win the war in a few weeks unless NATO used battlefield nuclear weapons to stop the advancing Warsaw Pact forces. This means, of course, also the risk of having to use nuclear weapons on West German territory; this use would inevitably result in the death of a large number of West German civilians and great damage to property. The cost to NATO in death and collateral damage of using battlefield nuclear weapons would be so high as to make this use incredible

    Directory of Open Access Journals (Sweden)

    Full Text Available The office of the Duchy of Warsaw Minister Secretary of State was created pursuant to the adoption of 1807 Basic Law. The Secretariat of State for the Duchy of Warsaw was an auxiliary apparatus for the minister State Secretary, with its main office located in Dresden, in consequence to the duties of the service. Thus, the office oper ated between 1807 and 1813. The responsibilities of the minister determined all the most important duties of the Secretariat of State. The system by which the administrative office had functioned was subordinate to those responsibilities. The quality of work, given the overload of assignments, had, at times, left much to be desired. However, The State Secretary Office was the only way, the citizens were able to contact the monarchy. The so-called HRH Cabinet of Stanislaw August was similar to the Saxon Cabinet, and the Secretariat of State served as the chancellery of the Saxon king. Therefore, in the case of this particular Royal Chancery, we can expect the preexisting order to be upheld rather than introduction of the new filing system, which is characteristic for the 19th century. The most important argument for applying the well-proven solutions in the Secretariat of State, was the fact, that the Saxon king was adverse to dramatic change. In spite of the fact that the Duchy of Warsaw had been introduced to modern political regime and way of operating the chancery, the Kingdom of Saxony was more conservative at the time. Fryderyk August was very cautious about the Duchy being reformed and he didn’t intend to introduce the same kind of changes to the Saxon state. This could also be the reason for his being skeptical about the modern approach to case filing. With regard to that, the solutions used to organise the secretariat of State were similar to the ones popular in the 18th century, modified, in order to cater to the needs of the affairs of the Duchy of Warsaw. Polish royal chancellery, which the Secretariat

    In 2009 the Polish Government made a decision to introduce nuclear power to Poland. Two nuclear power plants (NPPs) will be constructed nearly at the same time - the first unit should start operation in 2020, and by 2030 there should be about 6000 MWe added to the national electrical grid. The Commissioner of the Government was nominated to introduce the Polish Nuclear Power Program (PNPP). One of the four vertically integrated - the biggest energy company (PGE - the Polish Energy Group with headquarters in Warsaw) was appointed to prepare investments. These activities are planned in four stages: I. up to 31.12.2010 - The PNPP will be prepared and the program must then be accepted by the Government. II. 2011 - 2013 - Sites will be determined, and the contract for construction of the first NPP will be closed. III. 2014 - 2015 - Technical specifications will be prepared and accepted according the law. IV. 2016 - 2020 - The first NPP in Poland will be constructed. At present, the Government is receiving proposals from some regions of Poland asking that they be chosen for the NPP. One of the obvious locations for the NPP is a 40-kilometer vicinity of Warsaw (1.8 mln inhabitants). The need for both electric power and heat is increasing because of the rapidly growing town. It gives the extremely valuable chance for a very high thermodynamic efficiency of 80% in co-generation instead of 33% (max 36% for EPR-1600) for NPP generated electric power only. The Warsaw heating system has a capacity of 3950 MWt and is the biggest among EU countries. It is the third biggest in the world. Two NPPs, each of 2 x 1000 MWe could be built on the Vistula River up and down the town. In 2005, UE calculated losses caused by gas emissions at 24 mld eur, and the span of human lives was six months shorter in western countries and 8 months shorter in Poland. Warsaw's atmosphere is very polluted also because there are four heat and power generating plants: three coal and one oil -fired. In these

    like a mirror used by vain people? Youths and adults undertake dangerous and indecent acts in order to shoot themselves and publish the video. Also kill yourself could be easier through the web: while in Japan youths and adults make a “pact of death” with total strangers, in western countries they kill themselves alone in their room in front of the webcam. In eastern countries they try to escape from a society that rejects them, a society that accepts only the mask they show in public and not the inner side. In western countries, on the other side, we can find the lack of life values. They are not able to describe their feelings and emotions, so they only show their image through the web. Now, they want to play a leading role, crying all the words that has remained suppressed for so long time. They want to force the world to be a witness of their final decision.

    Veterans are challenged with multiple unique healthcare issues related to their military service environment. Likewise, health care providers must understand the special concerns associated with military conflict and recognize how the veteran's care can be optimized by interprofessional care delivery. Little is taught didactically or clinically that supports nursing students in addressing the unique issues of the veteran or the student's need to work collaboratively with allied health team members to enhance the veteran's care. Because of limited exposure to the veteran's special conditions, nursing students who may seek a career with the veteran population often face challenges in rendering appropriate care. The VA offers an invaluable opportunity for health profession students to collaborate with VA interprofessional Patient Aligned Care Teams (PACT) ultimately optimizing veteran health outcomes. This academic partnership, that implements an interprofessional model, will prepare students to better embrace the veteran population. This article describes the immersion of health profession students in interprofessional collaborative practice (IPCP) using PACT team principles which ultimately promotes the students' ability to link theory content to patient care delivery.

    Through the National Renewable Energy Laboratory (NREL), the United States Department of Energy (DOE) implemented the Wind Partnership for Advanced Component Technologies (WindPACT) program. This program will explore advanced technologies that may reduce the cost of energy (COE) from wind turbines. The initial step in the WindPACT program is a series of preliminary scaling studies intended to determine the optimum sizes for future turbines, help define sizing limits for certain critical technologies, and explore the potential for advanced technologies to contribute to reduced COE as turbine scales increase. This report documents the results of Technical Area 2-Turbine Rotor and Blade Logistics. For this report, we investigated the transportation, assembly, and crane logistics and costs associated with installation of a range of multi-megawatt-scale wind turbines. We focused on using currently available equipment, assembly techniques, and transportation system capabilities and limitations to hypothetically transport and install 50 wind turbines at a facility in south-central South Dakota

    DOE's Wind Partnerships for Advanced Component Technologies (WindPACT) program explores the most advanced wind-generating technologies for improving reliability and decreasing energy costs. The first step in the WindPact program is a scaling study to bound the optimum sizes for wind turbines, to define size limits for certain technologies, and to scale new technologies. The program is divided into four projects: Composite Blades for 80-120-meter Rotors; Turbine, Rotor, and Blade Logistics; Self-Erecting Tower and Nacelle Feasibility; and Balance-of-Station Cost. This report discusses balance-of-station costs, which includes the electrical power collector system, wind turbine foundations, communications and controls, meteorological equipment, access roadways, crane pads, and the maintenance building. The report is based on a conceptual 50-megawatt (MW) wind farm site near Mission, South Dakota. Cost comparisons are provided for four sizes of wind turbines: 750 kilowatt (kW), 2.5 MW, 5.0 MW, and 10.0 MW

    The aversive action of the pharmacological properties of ethanol was studied in selectively bred Warsaw Alcohol High-Preferring (WHP) and Warsaw Alcohol Low-Preferring (WLP) rats. For this study, a conditioned-taste aversion test was used. Male WHP and WLP rats were submitted to daily 20-min sessions for 5 days, in which a saccharin solution (1.0 g/L) was available (pre-conditioning phase). Next, this drinking was paired with the injection of ethanol (0, 0.5, 1.0 g/kg), intraperitoneally [i.p.] immediately after removal of the saccharin bottle (conditioning phase). Afterward, the choice between the saccharin solution and water was extended for 18 subsequent days for 20-min daily sessions (post-conditioning phase). Both doses of ethanol did not produce an aversion to saccharin in WLP and WHP rats in the conditioning phase. However, injection of the 1.0 g/kg dose of ethanol produced an aversion in WLP rats that was detected by a decrease in saccharin intake at days 1, 3, 7, and 10 of the post-conditioning phase, with a decrease in saccharin preference for 16 days of the post-conditioning phase. Conditioned taste aversion, measured as a decrease in saccharin intake and saccharin preference, was only visible in WHP rats at day 1 and day 3 of the post-conditioning phase. This difference between WLP and WHP rats was apparent despite similar blood ethanol levels in both rat lines following injection of 0.5 and 1.0 g/kg of ethanol. These results may suggest differing levels of aversion to the post-ingestional effects of ethanol between WLP and WHP rats. These differing levels of aversion may contribute to the selected line difference in ethanol preference in WHP and WLP rats. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available The genesis of the Warsaw Autumn Festival was fraught with both potential and real complications. Musical life in Poland at the end of the first postwar decade was in a state of flux, if not turmoil, as ideological disagreements and material complications contributed to an atmosphere of dismay and distrust among musicians and authorities. This paper provides insight into the context in which the Festival’s organizers were operating, particularly the shortcomings of musical life in mid-decade that threatened to derail the Festival before it even began.

    Traditional Informed Consent is becoming increasingly inadequate, especially in the context of research biobanks. How much information is needed by patients for their consent to be truly informed? How does the quality of the information they receive match up to the quality of the information they ought to receive? How can information be conveyed fairly about future, non-predictable lines of research? To circumvent these difficulties, some scholars have proposed that current consent guidelines should be reassessed, with trust being used as a guiding principle instead of information. Here, we analyse one of these proposals, based on a Participation Pact, which is already being offered to patients at the Istituto Europeo di Oncologia, a comprehensive cancer hospital in Milan, Italy. © 2015 John Wiley & Sons Ltd.

    Full Text Available This paper investigates the teaching continuing education as a public policy focused on confronting the illiteracy problem in the early years of elementary school, through the perceptions of 1.515 literacy teachers from the northwestern region of São Paulo that participated in the federal program Pacto Nacional pela Alfabetização na Idade Certa (National Pact for Literacy at the Right Age during the year 2013. Teacher education is discussed based on the authors Tardif, Imbernón and Nóvoa. To collect data, a questionnaire with open and closed questions available on an online server for researches was used. The methodology was qualitative and the data shows that the processes involved in conducting training, such as group work and methodology, are as valued as access to new knowledge.

    There are two general shortcomings to the current annual sparing assessment: 1. The vehicle functions are currently assessed according to confidence targets, which can be misleading- overly conservative or optimistic. 2. The current confidence levels are arbitrarily determined and do not account for epistemic uncertainty (lack of knowledge) in the ORU failure rate. There are two major categories of uncertainty that impact Sparing Assessment: (a) Aleatory Uncertainty: Natural variability in distribution of actual failures around an Mean Time Between Failure (MTBF) (b) Epistemic Uncertainty : Lack of knowledge about the true value of an Orbital Replacement Unit's (ORU) MTBF We propose an approach to revise confidence targets and account for both categories of uncertainty, an approach we call Probability and Confidence Trade-space (PACT) evaluation.

    2015-09-01

    Full Text Available This article raises the question of place attachment in the context of an increasingly important factor, that is the use of gathering and leisure places. The author publishes findings of a survey conducted among the residents of Zacisze, Warsaw, a detached housing estate with a very poor range of public places for gathering and leisure. The study has proved that the use of local public spaces, as a specific category of place, reinforces attachment to the whole housing estate. The study also confirms the important role that social factors have in building place attachment. Conditions already exist for considering social factors more important than physical ones in building a positive relationship with a territory.

    Monitoring the manufacturing process of silicon sensors is essential to ensure stable quality of the produced detectors. During the CMS silicon sensor production we were utilising small Test Structures (TS) incorporated on the cut-away of the wafers to measure certain process-relevant parameters. Experience from the CMS production and quality assurance led to enhancements of these TS. Another important application of TS is the commissioning of new vendors. The measurements provide us with a good understanding of the capabilities of a vendor's process. A first batch of the new TS was produced at the Institute of Electron Technology in Warsaw Poland. We will first review the improvements to the original CMS test structures and then discuss a selection of important measurements performed on this first batch.

    2015-09-01

    Full Text Available Social segregation is a subject common in contemporary studies of metropolitan areas. Until recently, studies of segregation focused on the distribution of ethnic groups, immigrants, and the poor. Today, they also cover additional indicators such as demographic properties, education, and affiliation with social and professional categories, which can also serve to determine the causes of the segregation (including the self-segregation of the rich. This article aims to point out the measures of segregation that present the segregation levels in the most complete manner, along with their application in the context of three European metropolitan areas: Warsaw, Berlin, and Paris. The first part of the article is a review of the existing approaches to segregation measures, followed by the selection of research method, presentation of the analysis’ results, and evaluation of the applied methods; presenting the opportunities and limitations in research of the social segregation phenomenon.

    2017-12-01

    Samples of historical terrazzo floor from the Jewish Historical Institute in Warsaw, dated back to the thirties of the twentieth century, have been analysed. Investigations by polarised optical microscopy, scanning microscopy, powder X-ray diffraction and simultaneous thermal analysis were preformed. Based on the results obtained, it was concluded that terrazzo tiles were prepared on the basis of ordinary Portland cement and aggregate, dominated with crushed stone (marble, serpentinite, limestone and marl), accompanied by sparse quartz sand grains. The binding mass was colourised with the use of pigments containing iron ions. The occurrence of altered serpentinite and marble grains, the latter clouded and partly replaced with micrite, the presence of portlandite, indicate the terrazzo tiles were subjected to thermal impact. This is related to the fire that took place at the beginning of World War II. Based on this study, repair mortars were formulated, on one hand compatible with the authentic ones, on the other retaining traces of fire.

    This paper describes the design of the central region for h=2 and 3 modes of acceleration in the Warsaw K-160 cyclotron. The central region is unique and compatible with the two above-mentioned harmonic modes of operation. Only one spiral type inflector will be used. The electric field distribution in the inflector and in the four acceleration gaps has been numerically calculated from an electric potential map produced by the program RELAX3D. The geometry of the central region has been tested with the computations of orbits carried out by means of the computer code CYCLONE. The optical properties of the spiral inflector and the central region were studied by using the programs CASINO and CYCLONE, respectively.

    Full Text Available Research into the determinants of companies’ decisions about paying out dividends, which has been described in the Polish specialist literature, concentrates mainly on the dividends actually paid out. The research presented in the article refers to declarations of the companies included in their dividend policies. The aim of the article is to present an attitude to dividend policy exhibited by the companies listed on the Warsaw stock exchange. A particular attempt was made at identifying various formulas of constructing dividend policies by the companies and the declared conditions for dividend payments and their amounts. 118 dividend companies took part in the research and they were selected from among the companies listed on the Warsaw stock exchange in the years 2006-2012. The authors have analysed the dividend policy of the companies in terms of its components and the way it was formulated, as well as the determinants of decisions about dividend payments declared by the companies. The results of the analysis were referred to the types of strategies of the dividend policy presented in the specialist literature. The research results indicate that the boards of many companies do not consider formulating and publicising the principles of making dividend payments to be a relevant area of investor relations. The dividend policy of the companies is usually formulated too generally, with the use of general statements. Satisfying capital needs for the planned development processes appears to be a basic determinant of the distribution of profit, which is why residual dividend policy is prevalent in the analysed companies.

    Full Text Available The objective of this study was to determine time trends (1982–2006 in total fat intake and changes in fatty acid structure intake in adolescents from Warsaw in view of increasing prevalence of obesity. Data come from four successive surveys randomly selected samples of adolescents (aged 11–15 years old, from Warsaw region. In total 9747 pupils have been examined, with response rate varying from 55% to 87% depending on year. Surveys were done always in the spring season of the year. Food intake was assessed by using 24 hours recall method of consumption by the pupils all products, including enriched, dishes and beverages as well as diet supplements, in the last 24 hours preceding the examination. The content of energy and nutrients was calculated by means of own computer softwares (DIET 2 and 4, taking into account successive revisions of the tables of food composition and nutritional values, as well as current Polish DRI. A significant decreasing trend was found in intake of total fat, of saturated fatty acids (SFA and cholesterol. The percentage of energy from total fat, also decreased both in boys (to 35,1% and girls (to 33,7%, what failed to reach the desired level below 30% of energy from fat which is recommended. Also significant decrease of SFA consumption was not satisfactory enough to approach the values <10% of energy recommended as was from 13% to 15%. Decreasing trends in fat intake was not in accordance with the trend in obesity prevalence in the adolescents as average BMI is going up. To stabilize the health-oriented changes especially in the diets of adolescents, further activity is desired from professionals working with prevention of adolescents obesity.

  8. The Lvov-Warsaw School: The forgotten tradition of historical psychology.

    Citlak, Amadeusz

    2016-05-01

    This article is an attempt to reconstruct the psychological achievements of the representatives of the Lvov-Warsaw School of historical psychology, virtually forgotten and unknown in the world's psychological literature. Kazimierz Twardowski (1866-1938), founder of the school, developed a philosophical and psychological program on the basis of (among other things) the theory of actions and products, including the research program that is now included in the thread of historical psychology. His student, Wladyslaw Witwicki (1878-1948), developed the cratism theory (the theory of power) on the basis Twardowski's assumptions, providing an alternative to Alfred Adler's theory of striving for superiority while also declaring it a few years before Adler. The consequence of Witwicki's theory and the methodological assumptions was the creation of psychobiography: the first nonpsychoanalytical psychobiography of Socrates (Witwicki, 1909, 1922) and the psychobiography of Jesus Christ (Witwicki, 1958). The school's activities weakened for political reasons, particularly the outbreak of the First World War. The members of the school dispersed after 1918, and they lost international connections with the world of science. Their significant achievements in the field of psychology remained unknown to psychologists for nearly a century. In this article, I would like to present the school's unique but unfinished program of reconstructing mental life through the psychological interpretation of cultural products (literature, arts, diaries), and its value for the practice of research in historical psychology. This program required additional development, but because of the war this never happened. Some of the school's theoretical findings and the first attempts to apply them have still significant value and show us the originality of Lvov-Warsaw School psychology.

    The objective of this paper is to summarize the outcomes of the Euroguidelines in Central and Eastern Europe (ECEE) conference held in Warsaw in February 2016. The main aim of this conference was to facilitate a discussion on European AIDS Clinical Society (EACS) guidelines implementation across the region and neighbouring countries and to present the current obstacles in benchmarking HIV care in Europe. During a 2-day meeting, there were country-based presentations using a predefined template so as to make the data comparable and focus the discussion. Areas covered were country epidemiology, surveillance, national strategy for treatment and prevention, standards of care, access to care and treatment availability. Each participant filled in a questionnaire investigating HIV guidelines usage per country. In total, 16 Central and Eastern Europe (CEE) and neighbouring countries were represented at the conference: Albania, Armenia, Belarus, Croatia, Czech Republic, Estonia, Georgia, Hungary, Lithuania, Moldova, Poland, Romania, Russia, Serbia, Slovakia and Turkey. EACS guidelines version 7.1 were used in 14 (87%) countries. In 11 (69%) countries, national guidelines were available, of which eight had been recently updated. Half of the countries declared that they use World Health Organization (WHO) and Department of Health and Human Services (DHHS) guidelines, over one-third the European Centre for Disease Prevention and Control (ECDC) HIV testing guidelines and one in five the International Antiviral Society-USA (IAS-USA) Panel guidelines from 2012. Participants declared their will to promote the widespread use of EACS guidelines for HIV infection in the CEE region and neighbouring countries by signing the Warsaw Declaration. They also emphasized the need to increase publishing of data from national cohorts in that region. © 2016 British HIV Association.

    This study documented baseline neurocognitive performance of 23,815 athletes on the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) test. Specifically, 9,733 Hispanic, Spanish-speaking athletes who completed the ImPACT test in English and 2,087 Hispanic, Spanish-speaking athletes who completed the test in Spanish were compared with 11,955 English-speaking athletes who completed the test in English. Athletes were assigned to age groups (13-15, 16-18). Results revealed a significant effect of language group (p Spanish-speaking athletes completing the test in Spanish scored more poorly than Spanish-speaking and English-speaking athletes completing the test in English, on all Composite scores and Total Symptom scores. Spanish-speaking athletes completing the test in English also performed more poorly than English-speaking athletes completing the test in English on three Composite scores. These differences in performance and reported symptoms highlight the need for caution in interpreting ImPACT test data for Hispanic Americans.

  11. Law, bioethics and practice in France: forging a new legislative pact.

    Berthiau, Denis

    2013-02-01

    In France, bioethics norms have emerged in close interaction with medical practices. The first bioethics laws were adopted in 1994, with provisions for updates in 2004 and most recently, in 2011. As in other countries, bioethics laws indirectly refer to certain fundamental values. The purpose of this paper is threefold. First, I shall briefly describe the construction of the French bioethics laws and the values they are meant to protect. Secondly, I will show that the practice of clinical ethics, as reported in a few studies on ART, living organ donation and PGD, challenge the role attributed to doctors as "gatekeepers" of those fundamental values. Thirdly, I will suggest that the quality of medical practices would improve if the law focused on strengthening the tacit pact between doctors and patients, rather than putting doctors in charge of enforcing societal values. Doctors, for their part, would limit their role to what they can do best: provide sufficient patient support and safe care. Against those who argue that we should dispense with bioethics laws altogether, I hold that the laws are useful in order to limit the development of abusive practices. However, a new legislative approach should be adopted which would a positive presumption in favor of patients' requests.

    Full Text Available Over the last few years laws and public policies have been developed to support women in building their status as citizens. However, advances in Brazilian legislation show us that they are no longer the formal aspects that inhibit women full process of citizenship. Thus, in this scenario it is important to discuss what are the improvements and challenges today for the implementation of the rights guaranteed by law. It is highlighted here the analysis of instruments promoted by the government through the policies and actions taken to guarantee the exercise of rights already provided by law. This article analyzes the main contributions of the National Pact to Combat Violence against Women and the State Plan of Policies for Women for the construction of female citizenship, in particular the plan adopted by the State of Minas Gerais, from the understanding that it should be constantly examined how federal entities are mobilized to the topic in question. The survey was exploratory in nature, developed from several sources. It concludes that although there are growing initiatives technical directives, there is still an undeniable fragility in the structure offered by the government to combat violence against.

  13. Too lonely to die alone: internet suicide pacts and existential suffering in Japan.

    Ozawa-de Silva, Chikako

    2008-12-01

    Most striking in the recent rise of suicide in Japan are the increase in suicide among young Japanese and the emergence of Internet suicide pacts. An ethnography of suicide-related Web sites reveals a distinctive kind of existential suffering among visitors that is not reducible to categories of mental illness and raises questions regarding the meaning of an individual "choice" to die, when this occurs in the context of an intersubjective decision by a group of strangers, each of whom is too afraid to die alone. Anthropology's recent turn to subjectivity enables analyses of individual suffering in society that provide a more nuanced approach to the apparent dichotomy between agency and structure and that connect the phenomenon of suicide in Japan to Japanese conceptions of selfhood and the afterlife. The absence of ikigai [the worth of living] among suicide Web site visitors and their view of suicide as a way of healing show, furthermore, that analyses of social suffering must be expanded to include questions of meaning and loss of meaning and, also, draw attention to Japanese conceptions of self in which relationality in all things, including the choice to die, is of utmost importance.

  14. The stability and growth pact in European Monetary Union. Institutional and economic foundations and a game-theoretical-experimental contribution to the credibility of sanctioning excessive deficits

    At the summit of the European Union (EU) in Amsterdam in June 1997, the Stability and Growth Pact has been concluded in order to ensure sound public finances in European Monetary Union (EMU). The pact's aim is to safeguard the compliance of EMU-member states with one of the Maastricht Treaty's fiscal convergence criteria, namely the requirement to hold a country's overall net deficit below 3 % of its GDP. Compliance within EMU shall be achieved by monetary sanctions against countries with an excessive deficit. Because the excessive deficit procedure, as laid down in the Maastricht Treaty, was rather loose, the stability and growth pact was formulated to clarify and speed up this procedure. The pact's effectiveness will essentially depend upon how strictly it will be applied. So far, the voting procedures in the EU-Council, which are crucial for sanctioning excessive deficits, has not been the subject of a detailed study in the literature on the pact. An analysis of the distribution of voting power when voting on an excessive deficit reveals that it is rather easy to bloc the imposition of sanctions, especially for relatively large EU-states and for those EMU-members opposing the imposition of sanctions. In addition to the institutional handicaps of the pact one can expect reciprocal voting behavior in the pact, which will further reduce the probability that a country with an excessive deficit in EMU will actually have to pay a fine. An experimental study into voting behavior in relatively small groups confirms this result. (author)

  15. Redefined Soviet military doctrine in perspective

    1992-01-01

    On May 29, 1987, the Warsaw Pact's Political Consultative Committee issued a communique proclaiming that the military doctrine of the Warsaw Pact member states is strictly defensive and proceeds from the fact that the application of military means to resolve any dispute is inadmissible under current conditions. Following this declaration, a corresponding redefinition of Soviet military doctrine to emphasize defensiveness and war prevention has evoke lively commentary and debate in both the West and the East. Because doctrinal issues are likely to retain significance during arms control and security negotiations. The purpose of this paper is to highlight important trends associated with a continuing dialogue over Soviet military doctrine and to assess what the future portends as doctrinal discussions unfold. Since 1987 the accelerating pace of change has accentuated the importance of doctrinally related concerns. As a result of the INF Treaty and the Stockholm agreement, there has been greater transparency regarding Soviet and Warsaw Pact military developments. On December 7, 1988, General Secretary Mikhail Gorbachev announced unilateral troop reduction over the next two years, which, when completed, would reduce the offensive capabilities of Soviet forces in Eastern Europe. In March 1989 talks on Confidence- and Security-Building Measures (CSBM) opened in Vienna, with suggestions for exchanges of views on military policy. At the very same time, NATO and the Warsaw Pact began formal negotiations on reduction of Conventional Forces in Europe (CFE) with a specific mandate to reduce those asymmetries that most favored prosecution of deep operations

    The aerosol layers of different origin, suspended in the atmosphere on 9-11 August 2015 were observed with the PollyXT-UW lidar in Warsaw, Poland. The HYSPLIT ensemble backward trajectories indicate that the observed air-masses attribute to a few different sources, among others, possible transport paths from Ukraine, Slovakia, and Africa. In this paper, we attempt to analyse and discuss the properties of aerosol particles of different origin that were suspended over Warsaw during this event.

    The aim of this study was to compare facial development in subjects with complete unilateral cleft lip and palate (CUCLP) treated with two different surgical protocols. Lateral cephalometric radiographs of 61 patients (42 boys, 19 girls; mean age, 10.9 years; SD, 1) treated consecutively in Warsaw with one-stage repair and 61 age-matched and sex-matched patients treated in Oslo with two-stage surgery were selected to evaluate craniofacial morphology. On each radiograph 13 angular and two ratio variables were measured in order to describe hard and soft tissues of the facial region. The analysis showed that differences between the groups were limited to hard tissues – the maxillary prominence in subjects from the Warsaw group was decreased by almost 4° in comparison with the Oslo group (sella-nasion-A-point (SNA) = 75.3° and 79.1°, respectively) and maxillo-mandibular morphology was less favorable in the Warsaw group than the Oslo group (ANB angle = 0.8° and 2.8°, respectively). The soft tissue contour was comparable in both groups. In conclusion, inter-group differences suggest a more favorable outcome in the Oslo group. However, the distinctiveness of facial morphology in background populations (ie, in Poles and Norwegians) could have contributed to the observed results.

    We have developed a refined and optimized version of the Warsaw Test Particle Model of interstellar neutral gas in the heliosphere, specially tailored for analysis of IBEX-Lo observations. The former version of the model was used in the analysis of neutral He observed by IBEX that resulted in an unexpected conclusion that the interstellar neutral He flow vector was different than previously thought and that a new population of neutral He, dubbed the Warm Breeze, exists in the heliosphere. It was also used in the reanalysis of Ulysses observations that confirmed the original findings on the flow vector, but suggested a significantly higher temperature. The present version of the model has two strains targeted for different applications, based on an identical paradigm, but differing in the implementation and in the treatment of ionization losses. We present the model in detail and discuss numerous effects related to the measurement process that potentially modify the resulting flux of ISN He observed by IBEX, and identify those of them that should not be omitted in the simulations to avoid biasing the results. This paper is part of a coordinated series of papers presenting the current state of analysis of IBEX-Lo observations of ISN He. Details of the analysis method are presented by Swaczyna et al. and results of the analysis are presented by Bzowski et al.

    In the Warsaw Ghetto established by the German Nazis as a special district for Polish Jews in 1940 there were two typhus epidemics. Many patients affected by this disease (1500 during the first and 6500 during second epidemic) were treated at The Department of Infectious Disease of Czyste Hospital headed by Dr Jakub Penson--a Polish physician of Jewish origin. A heroic group of 20 physicians not only treated patients in these tragic circumstances, but also performed in defiance of Nazi prohibition, scientific studies on the clinical course of typhus with special attention on hyperazotemia and renal complication. The results of their observations were presented in 1941-42 during clinical meetings in Czyste Hospital and later published by Penson in 1946 in the Polish Physicians Weekly. Among other clinical statements a description of acute renal failure of extrarenal origin, caused by dehydration and toxic influence of primary disease seems the most important one. It has to be taken into account that acute renal failure appearing during Crush Syndrome was described by Bywaters in 1941. Jakub Penson survived the German Nazi occupation and later become a head of the Internal Medicine Department in Gdansk Medical University and one of the precursors of clinical nephrology in Poland.

  3. Diagnostic Overlap between Fanconi Anemia and the Cohesinopathies: Roberts Syndrome and Warsaw Breakage Syndrome

    Full Text Available Fanconi anemia (FA is a recessively inherited disease characterized by multiple symptoms including growth retardation, skeletal abnormalities, and bone marrow failure. The FA diagnosis is complicated due to the fact that the clinical manifestations are both diverse and variable. A chromosomal breakage test using a DNA cross-linking agent, in which cells from an FA patient typically exhibit an extraordinarily sensitive response, has been considered the gold standard for the ultimate diagnosis of FA. In the majority of FA patients the test results are unambiguous, although in some cases the presence of hematopoietic mosaicism may complicate interpretation of the data. However, some diagnostic overlap with other syndromes has previously been noted in cases with Nijmegen breakage syndrome. Here we present results showing that misdiagnosis may also occur with patients suffering from two of the three currently known cohesinopathies, that is, Roberts syndrome (RBS and Warsaw breakage syndrome (WABS. This complication may be avoided by scoring metaphase chromosomes—in addition to chromosomal breakage—for spontaneously occurring premature centromere division, which is characteristic for RBS and WABS, but not for FA.

    Antioxidant vitamins such as alpha-tocopherol (vitamin E), ascorbic acid (vitamin C), and beta-carotene (provitamin A), play a significant role in protecting the body from an excess of free radicals. The vitamin content of the diet is thus very important. To assess whether the dietary intake of vitamins A, C and E is adequate in a selected group of adolescents living in Warsaw. The mean vitamin consumption was estimated using three-day dietary records whilst vitamin contents of selected foodstuffs were obtained from Food Composition Tables. Both were related to Polish nutrition standards applied to adolescents; i.e. EAR (Estimated Average Requirement) for vitamins A and C and AI (Adequate Intake) for vitamin E. Dietary vitamin C in adolescents and vitamin E in girls were around 18-25% lower than that recommended. Diets that were deficient in vitamins C and E were recorded in 47% to 67% adolescents. It is therefore necessary to increase the consumption of vegetables and fruit which provide a valuable dietary source for these vitamins.

    The proposed transfer of wastewater from the western part of Warsaw, across the Wisla (Vistula) River for joint treatment at the existing eastern side "Czajka" wastewater treatment plant (WWTP) will result in combined winter flows of approx. 580,000 m3 d(-1). One-year of pilot-scale studies defined the COD characteristics and kinetics of nitrogen removal and VFA production from primary sludge. BioWin simulation was used to size and price the optional processes and pointed to the Westbank process as the most cost-effective. The process consists of a sequence of a RAS pre-denitrification zone followed by an anaerobic, anoxic and aerobic zone. Some 100-150 t d(-1) of 10% methanol would be needed to remove 2-4 mg l(-1) of NO3-N above the recommended effluent level TN = 10 mg l(-1). Applying the principle of annual average 80% TN removal, and allowing for use of daily composite samples (rather than grab) could annually save the municipality over 1.5 million Euro on external carbon source.

  6. Does gentrification of the Praga Północ district in Warsaw really exist?

    Full Text Available Research on gentrification has been conducted for over 50 years by representatives of many disciplines. Modern gentrification is a process somewhat different from that originally described by R. Glass in 1964. Authors do not agree how to measure the process, nor how to explain its meaning (Bourne, 1993. Creating the right indicators is very difficult, especially if it is widely believed that gentrification, as a process identifying changes over time and a way of measuring dynamics, should enable the comparison of data from multiple years (Lees, 2010. The aim of this study was to identify the socio-spatial changes taking place in the Warsaw district of Praga Północ and to determine if it can be described as gentrification. The study area is a district stereotypically perceived as neglected, dangerous and deteriorated (e.g. Dudek-Mańkowska, 2011, at the same time subject to strong functional changes. Praga Północ is also an area of interest to many artists, creative industries and developers, and is undergoing gradual regeneration through municipal urban revitalization programs. It is also an area that the media portray as undergoing the process of gentrification. The results show that social and residential changes actually take place but the overall gentrification has not been felt by residents.

    Full Text Available This study presents the results of examination of the vegetation on the waste landfill of ArcelorMittal-Warszawa steel mill and the combustion waste landfill of Siekierki Power Station, both sites in Warsaw. The presented analyses of the field research contain detailed floristic-phytosociological data as well as botanical and ecological evaluation of the identified plants. The vegetative structures, together with the succession trends of the vegetation cover of two examined landfills, have been shown. Ecological habitat adaptations of plants and their spatial structure have been evaluated. The inventoried flora has been subjected to taxonomic, syntaxonomic and ecological classification. 154 plant species from 48 taxones in the range of families have been identified. Families characterized by the biggest abundance of species were: Compositae, grasses and Fabaceae. More than half of the live forms indentified were hemicryptophytes. The vegetation of two landfills has been dominated by synantrophic communities (Stellarietea mediae, Artemisietea vulgaris, Molinio-Arrhenatheretea, with apophytes being in the largest number. With the use of ecological indicators a broad ecological tolerance of the majority of species toward ecological factors has been observed.

    The opinion of future nursing professionals can influence the number of transplants. The objective of this study was to analyze the attitude of nursing students at the Medical University of Warsaw in the center of Poland toward organ donation and determine the factors that affect this attitude. The study was conducted in the 2011 to 2012 academic year. The study population consisted of nursing students. Type of sampling consisted of sampling in points of compulsory attendance, in the 5 nursing courses with the higher degree of fulfillment of 80%. Measuring instrument used was the validated questionnaire (PCID-DTO Rios). The questionnaire was completed anonymously and was self-administered. The completion rate was 96% (793 of 828). Of the students surveyed (n = 793), 69% (n = 547) were in favor of organ donation and transplantation, 25% (n = 201) were undecided, and 6% (n = 45) were against. This attitude was related to being in favor of donating the organs of a relative (OR = 3.174; P attitude toward donation and transplantation of the father (OR = 3.039; P = .001); considered to having good information on the subject (OR = 8.695; P attitude is conditioned by several psychosocial factors.

    Leishmaniasis, a protozoan parasitic disease that remains a major worldwide health problem with high endemicity in developing countries. Treatment of cutaneous Leishmaniasis (CL) should be decided by the clinical lesions, etiological species and its potential to develop into mucosal Leishmaniasis. High cost, systemic toxicity, and diminished efficacy due to development of parasite resistance are the serious drawbacks of current treatment options. Thus, identifying new, effective, and safer anti-leishmanial drug(s) is of paramount importance. The aim of this study was to verify the effectiveness of PACT in vitro, as a new technique for the treatment of Leishmaniasis. For this, semiconductor laser (λ = 660nm, 40mW, 8.4J/cm2, CW) associated to phenothiazine's derivatives (5 and 10 μg/ml, TBO, Methylene Blue or Phenothiazine) on the promastigotes form of Leishmania braziliensis in a single session was used. Viability of the parasites was assessed in quadruplicates of each group. The samples were removed and analyzed in a hemocytometer 72h after PACT. We found an important decrease in the number of viable parasites on all treated groups in comparison to their controls. The results of present study showed significant percentage of lethality (above 92%) of the protocol. The 98.33% of lethality was achieved with 10 μg/ml of FTZ. No lethality was seen on groups treated neither with laser nor with each compounds separately. The results are promising and indicative that the use of PACT may be a powerful treatment of Leishmaniasis when compared to already available ones.

    Leishmaniasis is a complex disease that affects more than 12 million people in 88 countries worldwide. Leishmania (Viannia) braziliensis is the most common species in the Americas and the most important causative agent of cutaneous and mucocutaneous leishmaniasis in Brazil. The therapeutic arsenal routinely employed to treat patients with leishmaniasis is limited and unsatisfactory. For cutaneous leishmaniasis, pentavalent antimonials are the first line therapeutic scheme recommended by the WHO. These compounds are highly toxic, poorly tolerated and their effectiveness highly variable. In this work, a technique with, so far, an unknown disadvantage is discussed. The aim of this study was to verify the effectiveness of PACT in vitro, as a new technique for the treatment of Leishmaniasis. For this, semiconductor laser (λ = 660nm, 40mW, 4.2J/cm2, CW) associated to phenothiazine's derivatives (5 and 10 μg/ml, TBO, Methylene Blue or Phenothiazine) on the promastigotes form of Leishmania braziliensis in a single session was used. Viability of the parasites was assessed in quadruplicates of each group. The samples were removed and analyzed in a hemocytometer 72h after PACT. We found an important decrease in the number of viable parasites on all treated groups in comparison to their controls. The results of present study showed significant percentage of lethality (above 95%) of the protocol. The 99.23% of lethality was achieved with 10 μg/ml of TBO. No lethality was seen on groups treated neither with laser nor with each compounds separately. The results are promising and indicative that the use of PACT may be a powerful treatment of leishmaniasis when compared to already available ones.

    The cytoplasmic RNA-induced silencing complex (RISC) contains dsRNA binding proteins, including protein kinase RNA activator (PACT), transactivation response RNA binding protein (TRBP), and Dicer, that process pre-microRNAs into mature microRNAs (miRNAs) that target specific mRNA species for regulation. There is increasing evidence for important functional interactions between the miRNA and nuclear receptor (NR) signaling networks, with recent data showing that estrogen, acting through the estrogen receptor, can modulate initial aspects of nuclear miRNA processing. Here, we show that the cytoplasmic RISC proteins PACT, TRBP, and Dicer are steroid receptor RNA activator (SRA) binding NR coregulators that target steroid-responsive promoters and regulate NR activity and downstream gene expression. Furthermore, each of the RISC proteins, together with Argonaute 2, associates with SRA and specific pre-microRNAs in both the nucleus and cytoplasm, providing evidence for links between NR-mediated transcription and some of the factors involved in miRNA processing.

  13. Is debt restructuring needed to make the Stability and Growth Pact (more credible?

    Full Text Available The emergence of the so-called PIIGS crisis which in 2009 became acute due to strongly diverging risk premiums, marked the beginning of a new phase for the European Monetary Union. Whilst the run-up to EMU had been characterized by an encouraging convergence of macroeconomic fundamentals of its member countries, it is now facing a serious threat in particular due to excessive levels of public debt. In 1997, the Stability and Growth Pact introduced a mechanism designed to prevent excessive public debt of the type currently observed; the fact of the matter, however, seems to be that levels of public debt has continuously grown from one economic cycle to the next. But the SGP apparently not only failed to fulfil its aim to keep the deficit and the debt level within its limits but also suffered from a severe loss of credibility; unless some profound action is taken it may further diminish, severely hampering the loose structure of the European Monetary Union. In order to regain some credibility, mitigate financial market’s concerns and, hence, lower borrowing cost, a consolidation path is needed to returns to acceptable levels of debt in the foreseeable future. This process has already started and measures have been taken by several eurozone countries to speed up fiscal consolidation. The aim of the paper is to analyze whether or not the group of the PIIGS countries are likely to return to debt levels in accordance with the SGP criteria or if it might be necessary to undergo a process of debt restructuring or default. By analysing different scenarios where nominal interest rates on debt (r and nominal growth rates (n as well as gaps thereof (r-n, herein called the automatic debt dynamics, are varied, this paper comes to the conclusion, that debt restructuring or default is a likely outcome for some of the PIIGS; arithmetics is in particular playing against Greece. As disillusioning and disappointing this outcome might be for some observers, it

    Visitor's access to understorey vegetation in park forest stands results in the impoverishment of plant species composition and a reduction in habitat quality. The phenomenon of biotic homogenisation is typical in urban landscapes, but it can proceed differently depending on the scale, a detail that has not been observed in previous studies. This research was carried out in seven Warsaw parks (both public and restricted access). Thirty-four forested areas were randomly selected, some subjected to strong visitors' pressure and some within restricted access areas, free of such impacts. The latter category included woodlands growing in old forest and secondary habitats. Public access to the study areas contributed to the disappearance of some forest species and their replacement by cosmopolitan non-forest species, leading to loss of floristic biodiversity in areas of high ecological importance at the city scale. Some human-induced factors, including soil compaction and changes in soil pH, moisture and capillary volume, were found to cause habitat changes that favoured native non-forest plants. Despite changes in species composition, the taxonomic similarity of understorey vegetation in both categories--public access and restricted access--was comparable. In a distance gradient of measurements taken around selected individual trees, there was found to be significant variation (in light, soil pH and compaction) affecting the quality and quantity of understorey vegetation (including rare species). In conclusion, the protection of rare forest species could be achieved by limiting access to forested areas, particularly in old forest fragments, and we highly recommend its consideration in the proposal of future park restoration plans.

  15. Contrasting academic and tobacco industry estimates of illicit cigarette trade: evidence from Warsaw, Poland.

    2014-05-01

    To compare two different methods for estimating the size of the illicit cigarette market with each other and to contrast the estimates obtained by these two methods with the results of an industry-commissioned study. We used two observational methods: collection of data from packs in smokers' personal possession, and collection of data from packs discarded on streets. The data were obtained in Warsaw, Poland in September 2011 and October 2011. We used tests of independence to compare the results based on the two methods, and to contrast those with the estimate from the industry-commissioned discarded pack collection conducted in September 2011. We found that the proportions of cigarette packs classified as not intended for the Polish market estimated by our two methods were not statistically different. These estimates were 14.6% (95% CI 10.8% to 19.4%) using the survey data (N=400) and 15.6% (95% CI 13.2% to 18.4%) using the discarded pack data (N=754). The industry estimate (22.9%) was higher by nearly a half compared with our estimates, and this difference is statistically significant. Our findings are consistent with previous evidence of the tobacco industry exaggerating the scope of illicit trade and with the general pattern of the industry manipulating evidence to mislead the debate on tobacco control policy in many countries. Collaboration between governments and the tobacco industry to estimate tobacco tax avoidance and evasion is likely to produce upward-biased estimates of illicit cigarette trade. If governments are presented with industry estimates, they should strictly require a disclosure of all methodological details and data used in generating these estimates, and should seek advice from independent experts.

    Full Text Available The aim of this paper is to investigate those buildings left over from Warsaw’s socialist past as a part of the city’s brand visual identity including their perception by foreign tourists and local citizens. Although Lisiak (2009 examined the destruction, removal and presence of these remnants from the socialist past in Central European cities, a comparative study of the perception of these architectural sites erected in Warsaw during socialist times has not been carried out specifically so far. To fill the gap, the authors concentrated research efforts on the following buildings: Palace of Culture and Science; the SMYK Store at Bracka 15/19; Ministry of Agriculture and Rural Development at Wspólna 30; Office Building and Atrium at Wspólna 62; and the former headquarters of the Polish Communist Party at Nowy Świat 6/12. These buildings were built after the Second World War between the late 1940s and the first half of the 1950s. With the exception of the Palace of Culture and Science - which is one of the most notable symbols of Warsaw - these architectural sites are not on a priority list of the average tourist who does little or no planning for their trip. Nevertheless, these buildings are connected to the Polish People’s Republic era and might attract different groups interested in this historical period and architecture. Apart from being potential tourist attractions, these buildings are being re-evaluated and restored to become integrated into the urban environment and more ‘comfortable’ for the local inhabitants. This paper gives some insights into the recognition and attractiveness of these architectural sites from the socialist past by those from Russia and the USA who have visited Warsaw as well as by Poles who know this city well. It is recommended that these results be taken into consideration by tourist agencies who deal with tours in Warsaw as well as institutions responsible for the city’s image. The authors express

    While the risk of adverse events following surgery has been identified, the impact of nursing care on early detection of these events is not well established. A systematic review of the evidence and an expert consensus study in post-anaesthetic care identified essential criteria for nursing assessment of patient readiness for discharge from the post-anaesthetic care unit (PACU). These criteria were included in a new nursing assessment tool, the Post-Anaesthetic Care Tool (PACT), and incorporated into the post-anaesthetic documentation at a large health service. The aim of this study is to test the clinical reliability of the PACT and evaluate whether the use of PACT will (1) enhance the recognition and response to patients at risk of deterioration in PACU; (2) improve documentation for handover from PACU nurse to ward nurse; (3) result in improved patient outcomes and (4) reduce healthcare costs. A prospective, non-randomised, pre-implementation and post-implementation design comparing: (1) patients (n=750) who have surgery prior to the implementation of the PACT and (2) patients (n=750) who have surgery after PACT. The study will examine the use of the tool through the observation of patient care and nursing handover. Patient outcomes and cost-effectiveness will be determined from health service data and medical record audit. Descriptive statistics will be used to describe the sample and compare the two patient groups (pre-intervention and post-intervention). Differences in patient outcomes between the two groups will be compared using the Cochran-Mantel-Haenszel test and regression analyses and reported as ORs with the corresponding 95% CIs. This study will test the clinical reliability and cost-effectiveness of the PACT. It is hypothesised that the PACT will enable nurses to recognise and respond to patients at risk of deterioration, improve handover to ward nurses, improve patient outcomes, and reduce healthcare costs.

    Full Text Available The primary function of the dsRNA binding protein (dsRBP PACT/RAX is to activate the dsRNA dependent protein kinase PKR in response to stress signals.  Additionally, it has been identified as a component of the small RNA processing pathway.  A role for PACT/RAX in this pathway represents an important interplay between two modes of post-transcriptional gene regulation.  The function of PACT/RAX in this context is poorly understood.  Thus, additional models are required to clarify the mechanism by which PACT/RAX functions.  In this study, Drosophila melanogaster was employed to identify functionally orthologous dsRNA-binding proteins.  Transgenic Drosophila expressing human PACT were generated to determine whether PACT is capable of functionally substituting for the Drosophila dsRBP R2D2, which has a well-defined role in small RNA biogenesis.  Results presented here indicate that PACT is unable to substitute for R2D2 at the whole organism level.

    Approximately 3.8 million sport and recreational concussions occur per year, creating a need for accurate diagnosis and management of concussions. Researchers and clinicians are exploring the potential dose-response cumulative effects of concussive injuries using computerized neuropsychological exams, however, results have been mixed and/or contradictory. This study starts with a large adolescent population and applies strict inclusion criteria to examine how previous mild traumatic brain injuries affect symptom reports and neurocognitive performance on the Immediate Post-concussion Assessment and Cognitive Testing (ImPACT) computerized tool. After applying exclusion criteria and case matching, 204 male and 99 female participants remained. These participants were grouped according to sex and the number of previous self-reported concussions and examined for overall differences on symptoms reported and scores obtained on the ImPACT neurocognitive battery composites. In an effort to further reduce confounding factors due to the varying group sizes, participants were then case matched on age, sex, and body mass index and analyzed for differences on symptoms reported and scores obtained on the ImPACT neurocognitive battery composites. Case matched analysis demonstrated males with concussions experience significantly higher rates of dizziness (p = .027, η 2  = .035), fogginess (p = .038, η 2  = .032), memory problems (p = .003, η 2  = .055), and concentration problems (p = .009, η 2  = .046) than males with no reported previous concussions. No significant effects were found for females, although females reporting two concussions demonstrated a slight trend for experiencing higher numbers of symptoms than females reporting no previous concussions. The results suggest that male adolescent athletes reporting multiple concussions have lingering concussive symptoms well after the last concussive event; however, these symptoms were found to

    To compare the dental arch relationship following one-stage repair of unilateral cleft lip and palate (UCLP) in Warsaw with a matched sample of patients treated by the Oslo Cleft Team. Study models of 61 children (mean age, 11.2; SD, 1.7) with a nonsyndromic complete UCLP consecutively treated with one-stage closure of the cleft at 9.2 months (range, 6.0 to 15.8 months; SD, 2.0) by the Warsaw Cleft Team at the Institute of Mother and Child, Poland, were compared with a sample drawn from a consecutive series of patients with UCLP treated by the Oslo Cleft Team and matched for age, gender, and soft tissue band. The study models were given random numbers to blind their origin. Four examiners rated the dental arch relationship using the GOSLON Yardstick. The strength of agreement of rating was assessed with weighted Kappa statistics. An independent t-test was carried out to compare the GOSLON scores between Warsaw and Oslo samples, and Fisher's exact tests were performed to evaluate the difference of distribution of the GOSLON scores. The intrarater and interrater agreements were high (K > or = .800). No difference in dental arch relationship between Warsaw and Oslo groups was found (mean GOSLON score = 2.68 and 2.65 for Warsaw and Oslo samples, respectively). The distribution of the GOSLON grades was similar in both groups. The dental arch relationship following one-stage repair (Warsaw protocol) was comparable with the outcome of the Oslo Cleft Team's protocol.

    Full Text Available In this article, we test the capital asset pricing model (CAPM on the Warsaw Stock Exchange (WSE by measuring the performance of two portfolios composed of construction firms: family-controlled and nonfamily controlled. These portfolios were selected from the WIG-Construction (WIG—Warszawski Indeks Giełdowy—Warsaw Stock Exchange Index. The performance of both portfolios was measured in the period from 2006 to 2012 with respect to three sub-periods: (1 pre-crisis period: 2006–2007; (2 crisis period: 2008–2009; and (3 post-crisis period: 2010–2012. This division was constructed in this way to find out how family firms performed in crisis times in relation to nonfamily firms. In addition, the construction portfolio was chosen due to its sensitivity to recessions. When an economy faces a downturn, construction firms are among the first to be exposed to risk. The performance was measured by using the capital asset pricing model with statistical inference. We find that public family firms significantly outperformed non-family peers in the crisis times.

    Full Text Available The aim of this study was to investigate how atmospheric air pollutants and meteorological conditions affected atmospheric visibility in the largest Polish agglomeration. The correlation analysis, principal component analysis (PCA and generalized regression models (GRMs were used to accomplish this objective. The meteorological parameters (temperature, relative humidity, precipitation, wind speed and insolation and concentrations of the air pollutants (PM10, SO2, NO2, CO and O3 were recorded in 2004–2013. The data came from the Ursynów-SGGW, MzWarszUrsynów and Okęcie monitoring stations, located in the south of Warsaw (Poland. It was shown that the PM10 concentration was the most important parameter affecting the visibility in Warsaw. The concentration, and indirectly the visibility, was mainly affected by the pollutant emission from the flat/building heating (combustion of various fuels. It changed intensively during the research period. There were also periods in which this emission type did not have a great influence on the pollutant concentrations (mainly PM10 and visibility. In such seasons, the research revealed the influence of the traffic emission and secondary aerosol formation processes on the visibility.

    Full Text Available The purpose of this paper is to identify the effects of the implementation of selected regulations on corporate governance in the reporting practice of banks listed on the Warsaw Stock Exchange. The survey examined the disclosures concerning the main features of the internal control and risk management systems in relation to financial reporting in banks. Research studies on disclosures related to control over financial reporting have not yet been conducted. The paper uses a research method involving the analysis of annual reports disclosed by banks. The method of induction was used in the process of inference. The results of the study indicate that in the practice of reporting of banks listed on the Warsaw Stock Exchange in 2011, there was no uniform reporting form in terms of the presentation of information on internal control or risk management systems in relation to financial reporting. The disclosures were different both in terms of level of detail and content. In some banks disclosures were drawn at a high level of generality.

    Nickel allergy is frequent and cause morbidity and increased health care costs. The aim of this study was to determine the proportion of inexpensive earrings randomly purchased from stores and street markets in two capitals that gave positive dimethylglyoxime (DMG) test reactions and to determine whether the degree of nickel release was related to shop category. Random inexpensive metallic earrings were purchased from stores and vendors in London and Warsaw. A qualitative investigation of nickel release by using the DMG test was performed. DMG testing revealed that respectively 15.1% (n=205) and 18.4% (n=206) of earrings purchased in London and Warsaw released nickel as indicated by positive test outcomes. Stratification by store category showed that DMG test-positive jewellery were mainly purchased from street markets and from stores that were not part of national or international chains. Despite the EU Nickel Directive having resulted in decreasing prevalence of nickel allergy, a large proportion of inexpensive earrings still release nickel in concentrations that may result in nickel allergy and dermatitis. Authorities should prioritize information campaigns and random inspections as a legislation that is not followed is of limited value. © 2010 The Authors.

    2014-11-01

    In our work copula functions and the Hurst exponent calculated using the local Detrended Fluctuation Analysis (DFA) were used to investigate the risk of investment made in shares traded on the Warsaw Stock Exchange. The combination of copula functions and the Hurst exponent calculated using local DFA is a new approach. For copula function analysis bivariate variables composed of shares prices of the PEKAO bank (a big bank with high capitalization) and other banks (PKOBP, BZ WBK, MBANK and HANDLOWY in decreasing capitalization order) and companies from other branches (KGHM-mining industry, PKNORLEN-petrol industry as well as ASSECO-software industry) were used. Hurst exponents were calculated for daily shares prices and used to predict high drops of those prices. It appeared to be a valuable indicator in the copula selection procedure, since Hurst exponent’s low values were pointing on heavily tailed copulas e.g. the Clayton one.

    Zagorski, Z.P.

    1999-01-01

    The IAEA has organized in Warsaw an International Conference on Large Radiation Sources in Industry from 8 to 12 September 1959. Proceedings of the Conference have been published in two volumes of summary amount of 925 pages. This report presents analysis, which technologies presented at the Conference have survived and why. The analysis is interesting because already in the fifties practically full range of possibilities of radiation processing was explored, and partially implemented. Not many new technologies were presented at the next IAEA Conferences on the same theme. Already at the time of the Warsaw Conference an important role of economy of the technology has recognized. The present report selects the achievements of the Conference into two groups: the first concerns technologies which have not been implemented in the next decades and the second group which is the basis of highly profitable, unsubsidized commercial production. The criterion of belonging of the technology to the second group, is the value of the quotient of the cost of the ready, saleable product diminished by the cost of a raw material before processing, to the expense of radiation processing, being the sum of irradiation cost and such operations as transportation of the object to and from the irradiation facility. Low value of the quotient, as compared to successful technologies is prophesying badly as concerns the future of the commercial proposal. A special position among objects of radiation processing is occupied by radiation processing technologies direct towards the protection or improving of the environment. Market economy does not apply here and the implementation has to be subsidized. (author)

He talked about the introduction of the Stability and Growth in a 'European quarter' which will be monitored in structural and fiscal policies of the Member States. He also held a first exchange of views about the possible introduction of a levy on banks and a tax on financial transactions. Thus, the European Union has moved to create the world's first supranational system of control over the financial markets, particularly in order to reduce the risk of global financial crisis. The system will act in early 2011. For the first time in history, European financial control agencies will have more seats than national governments. In addition, the European Central Bank will see a branch that will track the emergence of crisis risk.The financial crisis has diminished the EU's growth potential, and made it clear just how interdependent its members' economies are, particularly inside the eurozone. The most important priority now is to restore growth and create effective mechanisms for regulating financial markets - in Europe and internationally. In strengthening its system of economic governance, Europe must learn from previous shortcomings which have put the financial stability of the whole eurozone at risk:- poor observance of the EU's sound rules and procedures for economic policy coordination- insufficient reduction in public debt during the good times – with peer pressure proving an adequate incentive- failure to deal effectively with the build-up of macroeconomic imbalances - despite the Commission's warnings – resulting in high current account deficits, large external indebtedness and high public debt levels in a number of countries (above the official 60% limit for eurozone countries.

    Purpose: X-PACT is an experimental cancer therapy where kV x-rays are used to photo-activate anti-cancer therapeutics through phosphor intermediaries (phosphors that absorb x-rays and re-radiate as UV light). Clinical trials in pet dogs are currently underway (NC State College of Veterinary Medicine) and an essential component is the ability to model the kV dose in these dogs. Here we report the commissioning and characterization of a Monte Carlo (MC) treatment planning simulation tool to calculate X-PACT radiation doses in canine trials. Methods: FLUKA multi-particle MC simulation package was used to simulate a standard X-PACT radiation treatment beam of 80kVp with the Varian OBI x-ray source geometry. The beam quality was verified by comparing measured and simulated attenuation of the beam by various thicknesses of aluminum (2–4.6 mm) under narrow beam conditions (HVL). The beam parameters at commissioning were then corroborated using MC, characterized and verified with empirically collected commissioning data, including: percent depth dose curves (PDD), back-scatter factors (BSF), collimator scatter factor(s), and heel effect, etc. All simulations were conducted for N=30M histories at M=100 iterations. Results: HVL and PDD simulation data agreed with an average percent error of 2.42%±0.33 and 6.03%±1.58, respectively. The mean square error (MSE) values for HVL and PDD (0.07% and 0.50%) were low, as expected; however, longer simulations are required to validate convergence to the expected values. Qualitatively, pre- and post-filtration source spectra matched well with 80kVp references generated via SPEKTR software. Further validation of commissioning data simulation is underway in preparation for first-time 3D dose calculations with canine CBCT data. Conclusion: We have prepared a Monte Carlo simulation capable of accurate dose calculation for use with ongoing X-PACT canine clinical trials. Preliminary results show good agreement with measured data and hold

    The authors evaluate the quality of research reported in major journals in social-personality psychology by ranking those journals with respect to their N-pact Factors (NF)—the statistical power of the empirical studies they publish to detect typical effect sizes. Power is a particularly important attribute for evaluating research quality because, relative to studies that have low power, studies that have high power are more likely to (a) to provide accurate estimates of effects, (b) to produce literatures with low false positive rates, and (c) to lead to replicable findings. The authors show that the average sample size in social-personality research is 104 and that the power to detect the typical effect size in the field is approximately 50%. Moreover, they show that there is considerable variation among journals in sample sizes and power of the studies they publish, with some journals consistently publishing higher power studies than others. The authors hope that these rankings will be of use to authors who are choosing where to submit their best work, provide hiring and promotion committees with a superior way of quantifying journal quality, and encourage competition among journals to improve their NF rankings.

    Full Text Available In many human-modified tropical landscapes, biodiversity conservation and the provision of ecosystem services require large-scale restoration initiatives. Such initiatives must be able to augment the amount and the quality of remaining natural habitats. There is thus a growing need for long-term, multi-stakeholder and multi-purpose initiatives that result in multiple ecological and socioeconomic benefits at the biome scale. The Atlantic Forest Restoration Pact (AFRP is a coalition of 260+ stakeholders, including governmental agencies, private sector, NGOs and research institutions, aimed at restoring 15 million ha of degraded and deforested lands by 2050. By articulating, and then integrating common interests, this initiative has allowed different sectors of society to implement an ambitious vision and create a forum for public and private concerns regarding forest restoration. The AFRP adopts a set of governance tools so multiple actors can implement key processes to achieve long-term and visionary restoration goals. Having overcome some initial challenges, AFRP now has to incorporate underrepresented stakeholders and enhance its efforts to make forest restoration more economically viable, including cases where restoration could be less expensive and profitable. The AFRP experience has resulted in many lessons learned, which can be shared to foster similar initiatives across tropical regions.

    Full Text Available Abstract Background Globally, alcohol-related injuries cause millions of deaths and huge economic loss each year . The incidence of facial (jawbone fractures in the Northern Territory of Australia is second only to Greenland, due to a strong involvement of alcohol in its aetiology, and high levels of alcohol consumption. The highest incidences of alcohol-related trauma in the Territory are observed amongst patients in the Maxillofacial Surgery Unit of the Royal Darwin Hospital. Accordingly, this project aims to introduce screening and brief interventions into this unit, with the aims of changing health service provider practice, improving access to care, and improving patient outcomes. Methods Establishment of Project Governance: The project governance team includes a project manager, project leader, an Indigenous Reference Group (IRG and an Expert Reference Group (ERG. Development of a best practice pathway: PACT project researchers collaborate with clinical staff to develop a best practice pathway suited to the setting of the surgical unit. The pathway provides clear guidelines for screening, assessment, intervention and referral. Implementation: The developed pathway is introduced to the unit through staff training workshops and associate resources and adapted in response to staff feedback. Evaluation: File audits, post workshop questionnaires and semi-structured interviews are administered. Discussion This project allows direct transfer of research findings into clinical practice and can inform future hospital-based injury prevention strategies.

    It is not known whether early intervention can improve long-term autism symptom outcomes. We aimed to follow-up the Preschool Autism Communication Trial (PACT), to investigate whether the PACT intervention had a long-term effect on autism symptoms and continued effects on parent and child social interaction. PACT was a randomised controlled trial of a parent-mediated social communication intervention for children aged 2-4 years with core autism. Follow-up ascertainment was done at three specialised clinical services centres in the UK (London, Manchester, and Newcastle) at a median of 5·75 years (IQR 5·42-5·92) from the original trial endpoint. The main blinded outcomes were the comparative severity score (CSS) from the Autism Diagnostic Observation Schedule (ADOS), the Dyadic Communication Assessment Measure (DCMA) of the proportion of child initiatiations when interacting with the parent, and an expressive-receptive language composite. All analyses followed the intention-to-treat principle. PACT is registered with the ISRCTN registry, number ISRCTN58133827. 121 (80%) of the 152 trial participants (59 [77%] of 77 assigned to PACT intervention vs 62 [83%] of 75 assigned to treatment as usual) were traced and consented to be assessed between July, 2013, and September, 2014. Mean age at follow-up was 10·5 years (SD 0·8). Group difference in favour of the PACT intervention based on ADOS CSS of log-odds effect size (ES) was 0·64 (95% CI 0·07 to 1·20) at treatment endpoint and ES 0·70 (95% CI -0·05 to 1·47) at follow-up, giving an overall reduction in symptom severity over the course of the whole trial and follow-up period (ES 0·55, 95% CI 0·14 to 0·91, p=0·004). Group difference in DCMA child initiations at follow-up showed a Cohen's d ES of 0·29 (95% CI -0.02 to 0.57) and was significant over the course of the study (ES 0·33, 95% CI 0·11 to 0·57, p=0·004). There were no group differences in the language composite at follow-up (ES 0·15, 95% CI -0

    Between 1992 and 2004, air contamination with lead (Pb), cadmium (Cd), and zinc (Zn) in Warsaw, Poland, was monitored annually with moss (Sphagnum fallax) bags on a network of 230 sites covering the entire city. During the study the highest contamination was near the Warszawa Steel Mill, northwestern Warsaw. Lead concentrations in moss bags decreased in time, while those of Cd and Zn did not show clear trends. Between 1994 and 2004, Pb, Cd, and Zn were also monitored in the Crimean linden (Tilia Euchlora) foliage along the main city avenue and in a northwestern warsaw park. Lead concentrations decreased more near the avenue than in the park, indicating that the phasing-out of leaded gasoline had a major effect on reduced Pb contamination in Warsaw. At the same time, foliar concentrations of Cd and Zn in both areas decreased much less.

    Full Text Available Knowledge of the prevalence of ESBL enzymes among P. aeruginosa strains compared to the Enterobacteraiceae family is limited. The phenotypic tests recommended by EUCAST for the detection of ESBL-producing Enterobacteriaceae are not always suited for P. aeruginosa strains. This is mainly due to the presence of other families of ESBLs in P. aeruginosa isolates more often than in Enterobacteriaceae, production of natural AmpC cephalosporinase and its overexpression, and co-production of metallo-β-lactamases. The aim of this study was to determine the occurrence of ESBLs in P. aeruginosa isolated from patients from hospitals in Warsaw, to evaluate the ESBL production of these isolates using currently available phenotypic tests, their modifications, multiplex PCR and molecular typing of ESBL-positive isolates by PFGE. Clinical isolates of P. aeruginosa were collected in 2000-2014 from four Warsaw hospitals. Based on the data obtained in this study, we suggest using three DDST methods with inhibitors, such as clavulanic acid, sulbactam and imipenem, to detect ESBL-producing P. aeruginosa strains. Depending on the appearance of the plates, we suggest a reduction in the distance between discs with antibiotics to 15 mm and the addition of boronic acid at 0.4 mg per disc. The analysed isolates carried genes encoding ESBL from the families VEB (69 isolates with VEB-9, GES (6 with GES-1, 1 GES-5, 5 GES-13 and 2 with GES-15, OXA-2 (12 with OXA-15, 1 OXA-141, 1 OXA-210, 1 OXA-543 and 1 with OXA-544 and OXA-10 (5 isolates with OXA-74 and one with OXA-142. The most important result of this study was the discovery of three new genes, blaGES-15, blaOXA-141 and blaOXA-142; their nucleotide sequences have been submitted to the NCBI GenBank. It is also very important to note that this is the first report on the epidemiological problem of VEB-9-producing bacterial strains, not only in Poland but also worldwide.

    In July 2013, favorable weather conditions caused a severe events of advection of biomass burning particles of Canadian forest fires to Europe. The smoke layers were widely observed, especially in Western Europe. An unusual atmospheric aerosol composition was measured at the EARLINET site in Warsaw, Central Poland, during a short event that occurred between 11 and 21 UTC on 10th July 2013. Additionally to the smoke layer, mineral dust was detected in a separate layer. The long-range dust transport pathway followed an uncommon way; originating in Western Sahara, passing above middle Atlantic, and circulating over British Islands, prior to its arrival to Poland. An effective radius of 560 nm was obtained for Saharan dust over Warsaw. This relatively small effective radius is likely due to the long time of the transport. The aerosol-polarization-Raman PollyXT-UW lidar was used for a successful daytime Raman retrieval of the aerosol optical properties at selected times during this short event. The aerosol vertical structure during the inflow over Warsaw in terms of optical properties and depolarization was analyzed, indicating clear distinction of the layers. The microphysical properties were inverted from the lidar derived optical data for selected ranges as representing the smoke and the mineral dust. For smoke, the effective radius was in the range of 0.29-0.36 μm and the complex refractive index 1.36 + 0.008i, on average. For dust, the values of 0.33-0.56 μm and 1.56 + 0.004i were obtained. An evolution of the aerosol composition over Warsaw during the day was analyzed.

    Full Text Available A photodynamic effect occurs when photosensitiser molecules absorb light and dissipate the absorbed energy by transferring it to biological acceptors (usually oxygen, generating an excess of reactive species that are able to force cells into death pathways. Several tropical diseases present physiopathological aspects that are accessible to the application of a photosensitiser and local illumination. In addition, disease may be transmitted through infected blood donations, and many of the aetiological agents associated with tropical diseases have been shown to be susceptible to the photodynamic approach. However, there has been no systematic investigation of the application of photoantimicrobial agents in the various presentations, whether to human disease or to the disinfection of blood products or even as photo-insecticides. We aim in this review to report the advances in the photoantimicrobial approach that are beneficial to the field of anti-parasite therapy and also have the potential to facilitate the development of low-cost/high-efficiency protocols for underserved populations.

    Weather and climate are important natural resources for tourism and recreation, although sometimes they can make outdoor leisure activities less satisfying or even impossible. The aim of this work was to determine weather perception seasonal variability of people staying outdoors in urban environment for tourism and recreation, as well as to determine if personal factors influence estimation of recreationist actual biometeorological conditions and personal expectations towards weather elements. To investigate how human thermal sensations vary upon meteorological conditions typical for temperate climate, weather perception field researches were conducted in Warsaw (Poland) in all seasons. Urban recreationists' preference for slightly warm thermal conditions, sunny, windless and cloudless weather, were identified as well as PET values considered to be optimal for sightseeing were defined between 27.3 and 31.7 °C. The results confirmed existence of phenomena called alliesthesia, which manifested in divergent thermal perception of comparable biometeorological conditions in transitional seasons. The results suggest that recreationist thermal sensations differed from other interviewees' responses and were affected not only by physiological processes but they were also conditioned by psychological factors (i.e. attitude, expectations). Significant impact of respondents' place of origin and its climate on creating thermal sensations and preferences was observed. Sex and age influence thermal preferences, whereas state of acclimatization is related with thermal sensations to some point.

    2017-12-01

    Full Text Available The posters that accompany the successive Warsaw Autumn Festival editions are a unique collection of works, mostly of outstanding quality. One might venture the thesis that their artistic value – living up to the high demands of the topic – exceeds the typical standards of representation characteristic of popular art. Formally speaking, they abandon the conventions of egalitarian iconographic art in favour of a more elite-oriented visual formula, addressed to a competent audience knowledgeable about contemporary music and its qualities. The authors of these WA posters include many artists associated with the Polish school, such as Jan Lenica, Jan Młodożeniec, Julian Pałka, Waldemar Świerzy, Henryk Tomaszewski, and Wojciech Zamecznik. Their graphic representations of the achievements of the musical avant-garde do not, however, situate this poster series within the well-sanctioned canon of the “Polish poster school”, mostly associated with the film and theatre – generally considered as more “democratic” and entertainment-oriented disciplines of art.

    Full Text Available The types of organisms present in water reservoirs depend on water purity and biochemical processes that occur. Therefore, one of the methods of water quality assessment is to determine its condition by determining the biological indicators, including microbiological parameters. The aim of the experiment presented in this paper was to investigate the effects of selected physical and chemical parameters of water samples from the Vistula River on the microbiological status of water. The experiment was conducted in water samples collected in the central part of the Vistula River in Warsaw. The analyses of selected parameters were performed once a month throughout the year. Microbiological tests included: number of nitrogen fixing bacteria, MPN nitrifying bacteria, MPN sulfate-reducing bacteria. Physical and chemical parameters such as temperature, pH and total nitrogen content were determined in water samples. The results showed a correlation between temperature, pH and microbiological parameters. However, there was no significant correlation between the number of tested microorganisms and the concentration of total nitrogen in water samples.

    Full Text Available The paper presents the analysis of the II Underground Line construction’s impact on the Warsaw Scarp with the use of the electrical resistivity imaging (ERI, also known as the electrical resistivity tomography and further total station position measurements.The underground passes under the scarp perpendicular in the area of Dynasy Street 6, in Down-town district.The electrical resistivity imaging was performed for recognition of the geological structure and a potential land slide surface or zone.The gradient system was used during the prospection. In these analyses, the longitudinal section was 40 m long, and the depth of survey amounted to 6 m. In the case of the 200 m long transverse section, the resulted depth of survey was 30 m.The geophysical image of the longitudinal section,does not contain loosening soil zones,which could indicates lip surface.Next, total station measurements, which were tied to the archival geodetic observations’ results, were carried out. The aim of the measurements was to verify the activity of the horizontal and vertical displacements. The TBM excavation process led to summary vertical displacements up to approx. 24 mm and horizontal displacements amounting to approx. 13 mm. To sum up, the current land surveys reveals minor under ground line’ s construction impact on the scarp displacement. Nevertheless, the sensitive urban environment requires further monitoring, especially that the operation loads can result in displacement rate change.

    The paper presents technology and results of measurements of the steel construction of the skylight of the Main Hall of the Warsaw University of Technology. The new version of the automated measuring system has been used for measurements. This system is based on Leica TCRP1201+ total station and the TCcalc1200 software application, developed by the author, which operates on a laptop computer connected with the total station by the wire. Two test measurements were performed. Each of them consisted of cyclic measurement using the polar method, from one station; points located on the skylight construction, as well as control points located on concrete, bearing poles, were successively measured. Besides geometrical values (such as Hz, V angles and the slope distance D), the changes of temperature and atmospheric pressure, were also recorded. Processed results of measurements contained information concerning the behaviour of the skylight; asymmetry of horizontal displacements with respect to the X axis have been proved. Changes of parameters of the instrument telescope and changes of the instrument orientation were also stated; they were connected with changes of the temperature. The most important results of works have been presented in the form of diagrams.

    Full Text Available Vancomycin-resistant Enterococcus faecium represents a growing threat in hospital-acquired infections. Two outbreaks of this pathogen from neighboring Warsaw hospitals have been analyzed in this study. Pulsed-field gel electrophoresis (PFGE of SmaI-digested DNA, multilocus VNTR analysis (MLVA, and multilocus sequence typing (MLST revealed a clonal variability of isolates which belonged to three main lineages (17, 18, and 78 of nosocomial E. faecium. All isolates were multidrug resistant and carried several resistance, virulence, and plasmid-specific genes. Almost all isolates shared the same variant of Tn1546 transposon, characterized by the presence of insertion sequence ISEf1 and a point mutation in the vanA gene. In the majority of cases, this transposon was located on 50 kb or 100 kb pRUM-related plasmids, which lacked, however, the axe-txe toxin-antitoxin genes. 100 kb plasmid was easily transferred by conjugation and was found in various clonal backgrounds in both institutions, while 50 kb plasmid was not transferable and occurred solely in MT159/ST78 strains that disseminated clonally in one institution. Although molecular data indicated the spread of VRE between two institutions or a potential common source of this alert pathogen, epidemiological investigations did not reveal the possible route by which outbreak strains disseminated.

    During an exceptionally warm September of 2016, the unique, stable weather conditions over Poland allowed for an extensive testing of the new algorithm developed to improve the Meteosat Second Generation (MSG) Spinning Enhanced Visible and Infrared Imager (SEVIRI) aerosol optical depth (AOD) retrieval. The development was conducted in the frame of the ESA-ESRIN SAMIRA project. The new AOD algorithm aims at providing the aerosol optical depth maps over the territory of Poland with a high temporal resolution of 15 minutes. It was tested on the data set obtained between 11-16 September 2016, during which a day of relatively clean atmospheric background related to an Arctic airmass inflow was surrounded by a few days with well increased aerosol load of different origin. On the clean reference day, for estimating surface reflectance the AOD forecast available on-line via the Copernicus Atmosphere Monitoring Service (CAMS) was used. The obtained AOD maps were validated against AODs available within the Poland-AOD and AERONET networks, and with AOD values obtained from the PollyXT-UW lidar. of the University of Warsaw (UW).

    Full Text Available Successive significant amendments to wrestling regulations made competitors and coaches adapt technical-tactical actions to the needs of the new situation of the fight. The main objective of the study is an analysis of the course of a wrestling match in events of the rank of the European championships allowing a determination of dominant technical actions of Greco-Roman wrestlers at the age of 14-16 years. 221 competitors from 33 countries took part in Cadets' European Championships in the Greco-Roman style in Warsaw. An analysis of technical actions comprised all offensive and defensive actions both in the standing and in the kneeling position during every round of the fight. In 255 fights athletes performed 1500 technical actions and tactical operations, for which they received 2891 points in total. A method of secondary direct observation was used for observation of the course of a wrestling match. During Cadets' European Championships athletes most often used the technique "taking down" in the standing position (13%, and the "cart" during the fight in the kneeling position (27%.

    Full Text Available The study premises and objectives: The idea found at the basis of the discovery of a real value of cultural goods is underlined by the knowledge of their origins and history and of an environmental frame in which these have been produced. This theory could also be applied in regulations provided with certain newly introduced elements as: the absolute interdiction of thefts; the interdiction of destruction and execution of enemy property; the warning of before a terrestrial bombing with naval forces of ports, cities, villages, buildings or houses which are not defended The purpose on this paper is based on the following question: “Which of the gaps of humanitarian international law regarding cultural goods are surfacing?” The research models used are: the interpretative method, the structuralist-systematic method necessary for the knowledge of rules of organization and functioning of law as a system of social organization; the epistemological method, with an important role in the verification of an authentic meaning, fully manifesting the exigency regarding the protection of cultural property. The result of the study is obtained by offering an answer which as argued in this paper, concluding on one side that the discrepancies appeared between provisions (or dispositions of the Hague Convention of 1907 and the events of the First World War have led to an improved idea and to a completion of these norms. Conclusions: The preoccupation for the protection of cultural goods, of the people’s cultural patrimony, thus continues, even if, despite all acts adopted, we observe that certain states destroy willingly the treasures of other peoples. We have thus reached the conclusion that more drastic measures must be adopted more severe sanctions must be applied to states that neglect the norms of humanitarian international law and the existent gaps must be eliminated. For this reason the Second Protocol of The Hague Convention of 1954 has been promoted

    Meta-analyses show that exercise interventions during cancer treatment reduce cancer-related fatigue. However, little is known about the cost-effectiveness of such interventions. Here we aim to assess the cost-effectiveness of the 18-week physical activity during cancer treatment (PACT) intervention for patients with breast and colon cancer. The PACT trial showed beneficial effects for fatigue and physical fitness. Cost-effectiveness analyses with a 9-month time horizon (18 weeks of intervention and 18 weeks of follow-up) within the randomised controlled multicentre PACT study. Outpatient clinics of 7 hospitals in the Netherlands (1 academic and 6 general hospitals) PARTICIPANTS: 204 patients with breast cancer and 33 with colon cancer undergoing adjuvant treatment including chemotherapy. Supervised 1-hour aerobic and resistance exercise (twice per week for 18 weeks) or usual care. Costs, quality-adjusted life years (QALY) and the incremental cost-effectiveness ratio. For colon cancer, the cost-effectiveness analysis showed beneficial effects of the exercise intervention with incremental costs savings of €4321 and QALY improvements of 0.03. 100% of bootstrap simulations indicated that the intervention is dominant (ie, cheaper and more effective). For breast cancer, the results did not indicate that the exercise intervention was cost-effective. Incremental costs were €2912, and the incremental effect was 0.01 QALY. At a Dutch threshold value of €20 000 per QALY, the probability that the intervention is cost-effective was 2%. Our results suggest that the 18-week exercise programme was cost-effective for colon cancer, but not for breast cancer. ISRCTN43801571. Published by the BMJ Publishing Group Limited.

    The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is a commonly used tool in sports concussion assessment. While test-retest reliabilities have been established for the ImPACT cognitive composites, few studies have evaluated the psychometric properties of the ImPACT's Post-Concussion Symptom Scale (PCSS). The purpose of this study was to establish the test-retest reliability of symptom indices associated with the PCSS. Participants included 38 undergraduate students (50.0% male) who underwent neuropsychological testing as part of their participation in their psychology department's research subject pool. The majority of the participants were Caucasian (94.7%) and had no history of concussion (73.7%). All participants completed the ImPACT at two time points, approximately 6 weeks apart. The PCSS was the main outcome measure, and eight symptom indices were calculated (a total symptom score, three symptom summary indices, and four symptom clusters). Pearson correlations (r) and intraclass correlation coefficients (ICCs) were computed as measures of test-retest reliability. Overall, reliabilities ranged from low to high (r = .44 to .80; ICC = .44 to .77). The cognitive symptom cluster exhibited the highest test-retest reliability (r = .80, ICC = .77), followed by the positive symptom total (PST) index, an indicator of the total number of symptoms endorsed (r = .71, ICC = .69). In contrast, the commonly used total symptom score showed lower test-retest reliability (r = .67, ICC = .62). Paired-samples t tests revealed no significant differences between test and retest for any of the symptom variables (all p > .01). Finally, reliable change indices (RCI) were computed to determine whether differences observed between test and retest represented clinically significant change. RCI values were provided for each symptom index at the 80%, 90%, and 95% confidence intervals. These results suggest that evaluating additional symptom

    In the interest of preservation of high degree of objectivity of information about students' educational outcomes, a system of assessment needs to meet criteria of appropriate reliability and validity. Analysis of reliability and validity of the system of assessment of students' educational outcomes for courses followed by an examination and covered by a curriculum in Medical Rescue at Medical University of Warsaw (MU W). A retrospective study enrolling a group of 421 students of eight subsequent full education cycles. Detailed data concerning grades for fourteen courses followed by an examination in the entire course of studies were collected. Reliability (Cronbach's alpha coefficient) and criteria validity (Spearman's rank correlation) were assessed. Internal consistency was estimated using a multiple regression model. The levels of assessment reliability for the general university, pre-clinical, and clinical scopes amounted to alpha: 0.42, 0.53, and 0.70, respectively. The strongest positive correlations between the results of pre-clinical and clinical trainings were found for the Anatomy course (r ≈ 0.30). Only in the case of the Pharmacology course it was found that students' achievements in this field were significantly correlated with all other courses of clinical training. The influence of educational outcomes in particular areas of clinical training on the final grade for the entire course of studies was diverse (β regression between 0.04 and 0.11). While the Pharmacology course had the strongest impact on final results, the Surgery course had the least influence on students' final grades (β = 0.04). 1. Sufficient reliability of the system of assessment of educational outcomes in Medical Rescue showed good precision and repeatability of assessment. 2. A low level of validity was caused by a failure to keep the appropriateness of the assessment of educational outcomes in several clinical courses. 3.

    Between 1992 and 2004, air contamination with lead (Pb), cadmium (Cd), and zinc (Zn) in Warsaw, Poland, was monitored annually with moss (Sphagnum fallax) bags on a network of 230 sites covering the entire city. During the study the highest contamination was near the Warszawa Steel Mill, northwestern Warsaw. Lead concentrations in moss bags decreased in time, while those of Cd and Zn did not show clear trends. Between 1994 and 2004, Pb, Cd, and Zn were also monitored in the Crimean linden (Tilia Euchlora) foliage along the main city avenue and in a northwestern warsaw park. Lead concentrations decreased more near the avenue than in the park, indicating that the phasing-out of leaded gasoline had a major effect on reduced Pb contamination in Warsaw. At the same time, foliar concentrations of Cd and Zn in both areas decreased much less. - Between 1992 and 2004, concentrations of Pb decreased, while those of Cd and Zn remained little changed in moss bags and linden foliage exposed to ambient air in Warsaw, Poland.

    The conference was organized for celebrating the memory of professor Konstanty Janicki, one of the most important Polish zoologist, protistologist and parasitologist. Professors Joanna Pijanowska, Edward Siński and Maria Doligalska were the hosts of the meeting at the Warsaw University. Four lectures were given during the conference. Professor Leszek Kuźnicki presented professor Janicki's life and followers who continued his research. Professor Stanisław Kazubski reminded the main topics of the parasitological studies conducted by professor Janicki. That lecture was illustrated by coloured diagrams taken from original papers published by Janicki. In the next lecture, professor Teresa Pojmańska reminded "the theory of the cercomer". She viewed some polemics and discussions made by the opponents of the theory. Professor Alicja Guttowa presented a paper on the history of the exploration of the D. latum life cycle and the main scientific researches carried out on each life stages of the broad tapeworm. Afterwards the lectures, professor Kazubski showed several pictures taken inside and outside of the Main School of the Warsaw University at the time when professor Janicki had been working there. The professor's students were also seen in these pictures. Next, associate professor Bozena Moskwa, the President of the Polish Parasitological Society presented the Konstanty Janicki Medal, awarded for outstanding activities for the benefit of parasitology. Up to data, 17 scientists and one school: the Warsaw Uniwersity was honored with this Medal. After the conference, participants visited the Powazki Cementary, where the renovated sepulchral monument of professor Konstanty Janicki was uncovered.

    Regular consumption of a well balanced breakfast is a pre-requisite for normal growth and child development, along with the acquisition of proper eating habits. The family environment is crucial place where children learn such patterns of behaviour that form the basis for their development. To determine how family factors affect the regular eating of breakfast and types of foodstuffs consumed in primary school pupils, including food purchases made from vending machines and school tuck shops. Subjects were 836 pupils (435 girls and 401 boys, aged 6 - 13) from Warsaw and the surrounding areas. Appropriate socio-demographic data and relevant eating habits were obtained from direct interviewing of the subjects by means of a custom designed questionnaire. Statistical analyses were performed by the Kohonen type cluster analysis model and Chi-square test (Chi(2)); (p≤0.05). Three clusters of pupils were identified by their differing socio-demographics and eating habits (eg. rates of breakfast consumption, buying from vending machines or school tuck shops). The first and third clusters were mainly pupils from two-parent families with parents proportionally spending similar times at work, where respective breakfast (87% and 91%) and second breakfast (77% and 72%) consumption rates were also similar together with food shopping rates during school time (respectively 69% and 63%). Pupils with single-parents, multi-generation families or if both parents were profession- ally active, predominated in the second cluster. These ate breakfast (73%) and second breakfast (67%) more rarely, but more frequently shopped for food at school (84%). A small number of pupils had a packed second breakfast from home, rarely ate sandwiches, fruit and/or vegetables and dairy products but ate more sweets, sweet rolls and savoury snacks. However, a large number of subjects bought sandwiches, fresh fruit and/or vegetables and fast-food at school. Family factors were found to affect eating habits

    Coronaviruses (CoVs) are a huge threat to both humans and animals and have evolved elaborate mechanisms to antagonize interferons (IFNs). Nucleocapsid (N) protein is the most abundant viral protein in CoV-infected cells, and has been identified as an innate immunity antagonist in several CoVs, including mouse hepatitis virus (MHV) and severe acute respiratory syndrome (SARS)-CoV. However, the underlying molecular mechanism(s) remain unclear. In this study, we found that MHV N protein inhibited Sendai virus and poly(I:C)-induced IFN-β production by targeting a molecule upstream of retinoic acid-induced gene I (RIG-I) and melanoma differentiation gene 5 (MDA5). Further studies showed that both MHV and SARS-CoV N proteins directly interacted with protein activator of protein kinase R (PACT), a cellular dsRNA-binding protein that can bind to RIG-I and MDA5 to activate IFN production. The N-PACT interaction sequestered the association of PACT and RIG-I/MDA5, which in turn inhibited IFN-β production. However, the N proteins from porcine epidemic diarrhea virus (PEDV) and porcine reproductive and respiratory syndrome virus (PRRSV), which are also classified in the order Nidovirales, did not interact and counteract with PACT. Taken together, our present study confirms that both MHV and SARS-CoV N proteins can perturb the function of cellular PACT to circumvent the innate antiviral response. However, this strategy does not appear to be used by all CoVs N proteins.

    We introduce and evaluate an approach for obtaining closure between in situ and polarimetric remote sensing observations of smoke properties obtained during the collocated CIRPAS Twin Otter and ER-2 aircraft measurements of the Lebec fire event on July 8, 2016. We investigate the utility of multi-angle, spectropolarimetric remote sensing imagery to evaluate the relative contribution of organics, non-organic and black carbon particles to smoke particulate composition. The remote sensing data were collected during the Imaging Polarimetric and Characterization of Tropospheric Particular Matter (ImPACT-PM) field campaign by the Airborne Multiangle SpectroPolarimetric Imager (AirMSPI), which flew on NASA's high-altitude ER-2 aircraft. The ImPACT-PM field campaign was a joint JPL/Caltech effort to combine measurements from the Terra Multi-angle Imaging SpectroRadiometer (MISR), AirMSPI, in situ airborne measurements, and a chemical transport model to validate remote sensing retrievals of different types of airborne particulate matter with a particular emphasis on carbonaceous aerosols. The in-situ aerosol data were collected with a suite of Caltech instruments on board the CIRPAS Twin Otter aircraft and included the Aerosol Mass Spectrometer (AMS), the Differential Mobility Analyzer (DMA), and the Single Particle Soot Photometer (SP-2). The CIRPAS Twin Otter aircraft was also equipped with the Particle Soot Absorption Photometer (PSAP), nephelometer, a particle counter, and meteorological sensors. We found that the multi-angle polarimetric observations are capable of fire particulate emission monitoring by particle type as inferred from the in-situ airborne measurements. Modeling of retrieval sensitivities show that the characterization of black carbon is the most challenging. The work aims at evaluating multi-angle, spectropolarimetric capabilities for particulate matter characterization in support of the Multi-Angle Imager for Aerosols (MAIA) satellite investigation

    in-service training of healthcare workers is essential for improving healthcare services and outcome. The Millennium Development Goal (MDG) 6 Partnership for African Clinical Training (M-PACT) program was an innovative in-service training approach designed and implemented by the Royal College of Physicians (RCP) and West African College of Physicians (WACP) with funding from Eco Bank Foundation. The goal was to develop sustainable capacity to tackle MDG 6 targets in West Africa through better postgraduate medical education. Five training centres were establised: Nigeria (Abuja, Ibadan), Ghana (Accra), Senegal (Dakar) and Sierra Leone (Freetown) for training 681 physicians from across West Africa. A curriculum jointly designed by the RCP-WACP team was used to deliver biannual 5-day training courses over a 3-year period. Of 602 trained in clinical medicine, 358 (59.5%) were males and 535 (88.9%) were from hosting countries. 472 (78.4%) of participants received travel bursaries to participate, while 318 (52.8%) were residents in Internal Medicine in the respective institutions. Accra had the highest number of participants (29.7%) followed by Ibadan, (28.7%), Dakar, (24.9%), Abuja, (11.0%) and Freetown, (5.6%). Pre-course clinical knowledge scores ranged from 35.1% in the Freetown Course to 63.8% in Accra Course 1; whereas post-course scores ranged from 50.5% in the Freetown course to 73.8% in Accra course 1. M-PACT made a positive impact to quality and outcome of healthcare services in the region and is a model for continued improvement for healthcare outcomes, e.g malaria, HIV and TB incidence and mortality in West Africa.

  19. A new classification of parastomal hernias--from the experience at Bielański Hospital in Warsaw.

    Parastomal hernia is the most common local stoma complication. The incidence of parastomal hernia reaches 48%, and in a certain proportion of patients it is considered to be an inevitable consequence of stoma formation. The current classifications of parastomal hernias (Rubin, Devlin) are of little clinical value, which is supported by the fact that they have not been used in any publication presenting surgical treatment results in parastomal hernia. Moreover, these classifications do not include recommendations regarding surgical approach selection in those cases where surgical treatment is indicated. These disadvantages clearly indicate a need for developing a new classification of a greater practical value. was to present a suggested new parastomal hernia classification, based on structural criteria, and its use in surgical approach selection. The authors presented a group of 52 patients registered in Outpatient Stoma Clinic at Bielański Hospital in Warsaw, who had been diagnosed with parastomal hernia, defined as a type of hernia associated with postoperative artificial external intestinal fistula, who also had indications for surgical treatment of this stomal complication. These patients underwent a reconstructive procedure of their parastomal hernia with a surgical technique involving the placement of a monofilament polypropylene mesh in the preperitoneal space and repair of co-existing stomal complications using the variants of surgical techniques adequate for a given parastomal hernia type. Based on our studies and clinical experience, we propose a new classification of parastomal hernias, based on structural criteria. All hernias were divided into four groups (type I-IV) depending on hernia size and the presence of hernia in the postoperative scar. Qualification of a given hernia to a specific type was achieved based on physical examination, which makes the suggested classification a simple tool, useful in everyday practice. Each parastomal hernia type

    The aim of the study was to analyse the structure of involuntary psychiatric holds in Institute of Psychiatry and Neurology in Warsaw, throughout the year. Our research interests included socio-demographic profiles of the patients, time of admissions (time of a day/night/ season), type of diagnoses at admission and suicide attempts preceding the admission. We also analysed the normative aspect of involuntary admissions, i.e. which Articles of the Polish Mental Health Act constituted the basis for these patients admission, and if the choice of articles was justifiable by a diagnosis of the mental disorder. The primary research tool consisted of an original questionnaire allowing for the collection of relevant data. The material was submitted to statistical analysis, using primarily simple percentage methods. Involuntary psychiatric holds constituted 15.8% of the total number of admissions to the Institute of Psychiatry and Neurology (3,498 persons) in 2012. 522 persons with mental disorders were subject to involuntary admission on emergency basis (292 women and 260 men). Majority of patients was over 40 years old. The number of patients admitted to the Institute of Psychiatry and Neurology on emergency basis without the consent ranged from 38 to 62 people per month. Season did not differentiate significantly the number of admitted persons, majority of patients was admitted during the day (82%). Among the diagnosed patients, paranoid schizophrenia was the most frequent illness (43%), delirium tremens (7%), bipolar disorders (6%), dementia (5%), other psychotic disorders (5%), paranoid syndrome (5%), schizoaffective disorder (5%), other diagnoses (less than 1%). 4% of admissions to the Institute of Psychiatry and Neurology were due to attempted suicide. 37% of patients were admitted to the Institute of Psychiatry and Neurology under Article 23.1 of the Mental Health Act, 34% under Article 22.2, in accordance with Article 24.1 - only 7% of patients.

    2012-01-01

    In this book, a modern unified theory of dispersion forces on atoms and bodies is presented which covers a broad range of advanced aspects and scenarios. Macroscopic quantum electrodynamics is shown to provide a powerful framework for dispersion forces which allows for discussing general properties like their non-additivity and the relation between microscopic and macroscopic interactions. It is demonstrated how the general results can be used to obtain dispersion forces on atoms in the presence of bodies of various shapes and materials. Starting with a brief recapitulation of volume I, this volume II deals especially with bodies of irregular shapes, universal scaling laws, dynamical forces on excited atoms, enhanced forces in cavity quantum electrodynamics, non-equilibrium forces in thermal environments and quantum friction. The book gives both the specialist and those new to the field a thorough overview over recent results in the field. It provides a toolbox for studying dispersion forces in various contex...

    In response to the 1998 Institute of Medicine report, "Pacific Partnerships for Health ", acknowledging the need for the continuing education of health workers in the United States-Affiliated Pacific Island (USAPI) jurisdictions, the U.S. Health Resources and Services Administration (HRSA) awarded a grant (1999-2003) to the University of Washington for a continuing education project in the Pacific. When shortfalls in HRSA funding threatened continuation of the program, Pacific advocates aggressively made a case for refunding of this important project. In 2003, HRSA announced competitive funding for a new program for continuing education. The Department of Family Medicine and Community Health (DFMCH) at the University of Hawai'i (UH), John A. Burns School of Medicine (JABSOM) was awarded the HRSA Cooperative Agreement to run from September 2003 through August 2007, creating PACT the Pacific Association for Clinical Training. PACT assembled a professional, community-based advisory board, most of whom were indigenous Pacific Islanders, and conducted a continuing clinical education needs assessment in every jurisdiction, subsequently developing and delivering programs utilizing distance education relevant to the needs of each USAPI jurisdiction. Priority health areas included diabetes, oral health and geriatrics, as mandated by HRSA. This report describes the processes, accomplishments, challenges and lessons learned from the project. PACT needs assessment reports for each jurisdiction and an executive summary are published as Original Articles in this issue of Pacific Health Dialog. As funding for PACT comes to an end, it is clear that much work remains to be done in the region. "Continuing clinical education" is only one part of a continuum of human resources for health (HRH) workforce development. Continued USAPI regional, U.S. national and international collaboration and resources are needed to achieve the ultimate goal of improved health and health care delivery

    We employed a partnered research healthcare delivery redesign process to improve care for high-need, high-cost (HNHC) patients within the Veterans Affairs (VA) healthcare system. Health services researchers partnered with VA national and Palo Alto facility leadership and clinicians to: 1) analyze characteristics and utilization patterns of HNHC patients, 2) synthesize evidence about intensive management programs for HNHC patients, 3) conduct needs-assessment interviews with HNHC patients (n = 17) across medical, access, social, and mental health domains, 4) survey providers (n = 8) about care challenges for HNHC patients, and 5) design, implement, and evaluate a pilot Intensive Management Patient-Aligned Care Team (ImPACT) for a random sample of 150 patients. HNHC patients accounted for over half (52 %) of VA facility patient costs. Most (94 %) had three or more chronic conditions, and 60 % had a mental health diagnosis. Formative data analyses and qualitative assessments revealed a need for intensive case management, care coordination, transitions navigation, and social support and services. The ImPACT multidisciplinary team developed care processes to meet these needs, including direct access to team members (including after-hours), chronic disease management protocols, case management, and rapid interventions in response to health changes or acute service use. Two-thirds of invited patients (n = 101) enrolled in ImPACT, 87 % of whom remained actively engaged at 9 months. ImPACT is now serving as a model for a national VA intensive management demonstration project. Partnered research that incorporated population data analysis, evidence synthesis, and stakeholder needs assessments led to the successful redesign and implementation of services for HNHC patients. The rigorous design process and evaluation facilitated dissemination of the intervention within the VA healthcare system. Employing partnered research to redesign care for high-need, high

    Patient-centred care is essential to the delivery of healthcare; however, this necessitates direct patient involvement in clinical decision-making and can be challenging for patients diagnosed with advanced non-small cell lung cancer where there may be misunderstanding of the extent of disease, prognosis and aims of treatment. In this context, decisions are complex and there is a need to balance the risks and benefits, including treatment with palliative intent. The aim of the PACT study is to identify the information and decision support needs of patients, leading to the development of an intervention to support patients with advanced lung cancer when considering treatment options. PACT is a five-stage, multimethod and multicentre study. Participants : Patients and health professionals will be recruited from three health boards. Methods : Non-participant observation of multidisciplinary team meetings (n=12) will be used to determine patients' allocation to treatment pathways (stage I). Non-participant observation of patient-clinician consultations (n=20-30) will be used to explore communication of treatment options and decision-making. Extent of participation in decision-making will be assessed using the Observing Patient Involvement in Shared Decision-Making tool. Interviews with patients (stage III) and their clinicians (stage IV) will explore the perception of treatment options and involvement in decision-making. Based on stages I-IV, an expert consensus meeting will finalise the content and format of the intervention. Cognitive interviews with patients will then determine the face validity of the intervention (stage V). Analysis : analysis will be according to data type and research question and will include mediated discourse analysis, thematic analysis, framework analysis and interpretative phenomenological analysis. Ethical approval has been granted. The study findings will contribute to and promote shared and informed decision-making in the best interest

    This study aimed to evaluate the impact of a primary prevention intervention program on risk behavior for allergic diseases among children up to 2 years of age. The setting was in ordinary pre- and postnatal primary health care in Trondheim, Norway. The Prevention of Allergy among Children in Trondheim, Norway (PACT) study invited all pregnant women and parents to children up to 2 years of age in the community to participate in a non-randomized, controlled, multiple life-style intervention study. Interventional topics was increased dietary intake of cod liver oil and oily fish for women during pregnancy and for infants during the first 2 years of life, reduced parental smoking and reduced indoor dampness. A control cohort was established prior to the intervention cohort with "follow up as usual". Questionnaires were completed in pregnancy, 6 weeks after birth and at 1 and 2 years of age. Trends in exposure and behavior are described. Intake of oily fish and cod liver oil increased statistically significantly among women and infants in the intervention cohort compared to the control cohort. There was a low postnatal smoking prevalence in both cohorts, with a trend towards a decreasing smoking prevalence in the control cohort. There was no change in indoor dampness or in behavior related to non- intervened life-style factors. The dietary intervention seemed to be successful. The observed reduced smoking behavior could not be attributed to the intervention program, and the latter had no effect on indoor dampness.

    The PACT-Denbaya project (Program for community access to telemedicine for families) aimed to help improve the health of mothers and child in rural communities through the delegation of obstetric-gynecologic and pediatric tasks, supported by teleconsultations. This operational research took place in 6 community health centers in the Dioïla health district in Mali. Our method was based of the delegation of tasks, supported by teleconsultations. Experts in pediatrics and obstetrics/gynecology provided a week-long training program to general practitioners and midwives, in the management of the most common problems in the field and in the use of the "Bogou" teleconsultation and "Dudal" tele-education platforms to ensure exchanges and follow-up. Overall, 17 healthcare providers, that is, general practitioners, nurse-obstetricians, and midwives participated in sessions to strengthen gynecology-obstetric and pediatric capacity in the field. The evaluation of knowledge and of the indicators compared with the baseline of 8359 pregnancies and 1991 documented deliveries and of user satisfaction showed that this type of service resulted in decreased maternal and child mortality. In view of these results, we can deduce that the delegation of tasks, when it is supported by telehealth, encounters no resistance from the specialists and contributes to the significant improvement of maternal and infant health in remote areas. A long-term impact study is necessary to reinforce these results.

    2013-02-01

    Sedentary behaviour and reduced exercise capacity are potential persisting effects of anti-cancer therapy that may predispose to serious health conditions. It is well-established that physical exercise may prevent some of these problems. However, the extent to which cancer survivors are able to adopt long-term physical activity habits depends largely on their motivation. This theoretical paper aims to outline how researchers and practitioners can draw from Antonovsky's salutogenetic theory and White & Epston's Narrative Therapy to develop and implement intervention efforts centered on promotion of long-term physical activity behaviour, while at the same time increasing the individual cancer survivor's sense of meaning and personal health resources. The Copenhagen PACT (Physical Activity after Cancer Treatment) Study targeting adoption and maintenance of regular physical activity in post-therapy cancer survivors is briefly presented including a brief review of the theoretical rationale behind the psychological component of the intervention, i.e. a narrative-based exercise counselling programme. Subsequently, particular attention is given to the core principles, different components and structure of the counselling manual including sample questions and examples of written documents that have emanated from the individual counselling sessions. The discussion includes consideration of some methodological challenges that arise when attempting to evaluate narrative-based interventions in the context of physical activity promotion in cancer rehabilitation and survivorship care.

    To reduce energy consumption and improve residents' quality of life, "smart cities" should use not only modern technologies, but also the social innovations of the "Internet of Things" (IoT) era. This article attempts to solve transport problems in a smart city's office district by utilizing gamification that incentivizes the carpooling system. The goal of the devised system is to significantly reduce the number of cars, and, consequently, to alleviate traffic jams, as well as to curb pollution and energy consumption. A representative sample of the statistical population of people working in one of the biggest office hubs in Poland (the so-called "Mordor of Warsaw") was surveyed. The collected data were processed using spatial data mining methods, and the results were a set of parameters for the multi-agent system. This approach made it possible to run a series of simulations on a set of 100,000 agents and to select an effective gamification methodology that supports the carpooling process. The implementation of the proposed solutions (a "serious game" variation of urban games) would help to reduce the number of cars by several dozen percent, significantly reduce energy consumption, eliminate traffic jams, and increase the activity of the smart city residents.

    Infections in human body caused by various microbes are a significant problem in modern medicine. Special attention is put to infections of wounds, which are a significant threat to the life of patients. Attempts to treat these wounds base mainly on the application of various chemical preparations (locally) and systematic antibiotic treatment. UV radiation, because of its anti-bacterial activity, appear a complementary issue in therapy. AIM OF THE SURVEY: The aim of this study was an examination of the sensitivity of bacteria strains isolated from patients hospitalised in the Warsaw Medical University clinics, and prove that antibiotics and operation of UV B and C radiation with Endolamp 474 may become a complementary or alternative method of treatment. The study used 65 strains grown aerobically (15 strains of Escherichia coli, 20 strains of Pseudomonas aeruginosa, 15 strains of Staphylococcus aureus, 15 strains of Streptococcus and Enterococcus sp). The same strains were planted on different excipients and were subjected to UV radiation using Endolamp 474. Correctly prepared strains were radiated from a 25 cm distance in various durations (from 5 seconds to 105 seconds). As a result of UV irradiation of microorganisms studied B and C using 474 Endolampy received varied, but the great sensitivity to the effects of this radiation, in all tested bacterial strains. UV radiation on microorganisms requires further study, also in vivo.

    Immunosuppresive therapy following organ transplant frequently includes treatment with tacrolimus and mycophenolic acid derivatives. These pharmaceuticals may enter the environment through wastewater treatment plant (WWTP) effluents and may have a potentially harmful effect on aquatic biota. Tacrolimus, mycophenolic acid and their metabolites were measured at specific points of a large Polish river (Vistula), a smaller river (Utrata) and in tap water samples from the Warsaw region. Analysis was performed using liquid chromatography tandem mass spectrometry, after solid phase extraction for water samples, or QuEChERS extraction for sediments. Residues of tacrolimus were below quantitation limits in both water and sediment samples. However, in water samples mycophenolic acid concentrations were measured at up to 180 ng L(-1) downstream of WWTP outfalls. No immunosuppressive drugs were detected in tap water. Concentrations of mycophenolic acid exceeded the predicted no effect concentration (PNEC) value in some Polish surface water, and risk calculations predicted at least twice higher concentrations in some other countries of the European Union. To the best of the authors' knowledge, this is the first report of these immunosuppressive drug concentrations in the environment. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available The reaction of marginal investors to the announcement of a surprise dividend increase has been measured. Although field research is performed on companies listed on the Warsaw Stock Exchange, the paper has important theoretical implications. Valuation theory gives many clues for the interpretation of changes in dividends. At the start of the literature review, the assumption of the irrelevance of dividends (to investment decisions is described. This assumption is the basis for up-to-date valuation procedures leading to fundamental and fair market valuation of equity (shares. The paper is designed to verify whether the market value of stock is immune to the surprise announcement of a dividend increase. This study of the effect of a surprise dividend increase gives the chance to partially isolate such an event from dividend changes based on long-term expectations. The result of the research explicitly shows that a surprise dividend increase is on average welcomed by investors (an average abnormal return of 2.24% with an associated p-value of 0.001. Abnormal returns are realized by investors when there is a surprise increase in a dividend payout. The subsample of relatively high increases in a dividend payout enables investors to gain a 3.2% return on average. The results show that valuation models should be revised to take into account a possible impact of dividend changes on investors behavior. (original abstract

    2014-06-01

    Full Text Available The article aims to describe and compare journalistic frames of climate change produced by two leading newspapers in South America: Clarin of Argentina and Folha de São Paulo of Brazil, in the context of the Doha (COP- 18 and Warsaw (COP -19 conferences. For this, it has used a definition of framing which recognizes its various dimensions: definition of the situation, reasoning about causes, moral evaluations and recommendations or prescriptions. The analysis was addressed by a qualitative process of coding and classification of journalistic texts. The empirical results indicate that the frames produced for the newspapers correspond to the political context to which they belong, that they coincide in pointing to climate change as a serious problem caused primarily by industrialized countries and what must be faced with a sense of urgency, so they tend to legitimate climate policy. In this regard, it is noted that journalistic frames not only guide the interpretation of social problems, but legitimate political action.

    As the result of the communist terror in Poland, during years 1944-1956 more than 50,000 people died. Their bodies were buried secretly, and most places are still unknown. The research presents the results of identification of people buried in one of many mass graves, which were found at the cemetery Powązki Military in Warsaw, Poland. Exhumation revealed the remains of eight people, among which seven were identified genetically. Well-preserved molars were used for the study. Reference material was collected from the closest living relatives. In one case, an exhumation of victim's parents had to be performed. DNA from swabs was extracted with a PrepFiler ® BTA Forensic DNA Extraction Kit and organic method. Autosomal, Y-STR amplification, and mtDNA sequencing were performed. The biostatistical calculations resulted in LR values from 1608 to 928 × 10 18 . So far, remains of more than 50 victims were identified. © 2016 American Academy of Forensic Sciences.

    Full Text Available From the mid-16th century onwards, the Apostolic Nunciature in Poland was pro-parliamentary, anti-Turkish and counter-reformative. It should not come as a surprise that the preliminary instruction issued to nuncio Giovanni Battista Lacellotti to stay especially alert and secure the interest of the Catholic Church in Poland as well as care for Christian affairs during parliamentary sessions acquired particular significance. In early November 1622, by the appointment of cardinal Cosimo de Torres, under Gregory's XV papal brief of 3 December 1622, Antonio Francesco Cirioli became internuncio. A Bolognese by origin, Cirioli was and a Doctor of Laws and from 1621 an auditor of Cosimo de Torres's nunciature (to date completely absent from the literature of the subject. The office of the internuncio in Warsaw, to which he was appointed following his 13-month service as an auditor, was held by Cirioli for as many as twenty-three weeks, i.e. from 19 November 1622 to 29 April 1623.

    Patient-centered medical homes have made great strides providing comprehensive care for patients with chronic conditions, but may not provide sufficient support for patients at highest risk for acute care use. To address this, the Veterans Health Administration (VHA) initiated a five-site demonstration project to evaluate the effectiveness of augmenting the VA's Patient Aligned Care Team (PACT) medical home with PACT Intensive Management (PIM) teams for Veterans at highest risk for hospitalization. Researchers partnered with VHA leadership to design a mixed-methods prospective multi-site evaluation that met leadership's desire for a rigorous evaluation conducted as quality improvement rather than research. We conducted a randomized QI evaluation and assigned high-risk patients to participate in PIM and compared them with high-risk Veterans receiving usual care through PACT. The summative evaluation examines whether PIM: 1) decreases VHA emergency department and hospital use; 2) increases satisfaction with VHA care; 3) decreases provider burnout; and 4) generates positive returns on investment. The formative evaluation aims to support improved care for high-risk patients at demonstration sites and to inform future initiatives for high-risk patients. The evaluation was reviewed by representatives from the VHA Office of Research and Development and the Office of Research Oversight and met criteria for quality improvement. VHA aims to function as a learning organization by rapidly implementing and rigorously testing QI innovations prior to final program or policy development. We observed challenges and opportunities in designing an evaluation consistent with QI standards and operations priorities, while also maintaining scientific rigor.

    The microprocessor complex mediates intranuclear biogenesis of precursor microRNAs from the primary microRNA transcript. Extranuclear, mature microRNAs are incorporated into the RNA-induced silencing complex (RISC) before interaction with complementary target mRNA leads to transcriptional repression or cleavage. In this study, we investigated the expression profiles of the microprocessor complex subunit DiGeorge syndrome critical region gene 8 (DGCR8) and the RISC components argonaute-1 (AGO1), argonaute-2 (AGO2), as well as double-stranded RNA-binding proteins PACT, TARBP1, and TARBP2 in epithelial skin cancer and its premalignant stage. Patients with premalignant actinic keratoses (AK, n = 6), basal cell carcinomas (BCC, n = 15), and squamous cell carcinomas (SCC, n = 7) were included in the study. Punch biopsies were harvested from the center of the tumors (lesional), from healthy skin sites (intraindividual controls), and from healthy skin sites in a healthy control group (n = 16; interindividual control). The DGCR8, AGO1, AGO2, PACT, TARBP1, and TARBP2 mRNA expression levels were detected by quantitative real-time reverse transcriptase polymerase chain reaction. The DGCR8, AGO1, AGO2, PACT, and TARBP1 expression levels were significantly higher in the AK, BCC, and SCC groups than the healthy controls (P  0.05). This study indicates that major components of the miRNA pathway, such as the microprocessor complex and RISC, are dysregulated in epithelial skin cancer. Copyright © 2011 Wiley Periodicals, Inc.

  9. THE MOMENTUM EFFECT EXEMPLIFIES THE INFLUENCE OF INVESTORS’ IRRATIONAL BEHAVIOUR ON CHANGING PRICES OF SHARES AND STOCKS: AN ANALYSIS OF THE MOMENTUM EFFECT ON THE WARSAW STOCK EXCHANGE

    Full Text Available An efficient market should not show any anomalies. When new information reaches a market which is efficient, it should automatically translate into prices of assets, which ought to eliminate the possibility of gaining an advantage over other investors, thus preventing excess profits. However, studies on capital markets indicate that in reality it is possible to earn unusually high profits by taking advantage of certain anomalies which occur on a given market. Among such anomalies there is the momentum effect. This study performed on the Stock Exchange in Warsaw has shown that the momentum effect occurred throughout the entire analyzed time period. Positive returns demonstrated for investment strategies based on the momentum effect were unexplainable by the classical theory of finances. A correlation was found between the economic situation on the stock exchange and portfolio return rates, but it was too weak to attribute the effect to a single decisive factor. In addition, the returns from investments based on the momentum effect were statistically higher in January than in the other months, which was caused by the January effect, stimulating the occurrence of statistically higher returns at the beginning of a year rather than later on during the analyzed period of time. Research in this field carried out in other countries justifies the claim that there are many irrational factors which together create the momentum effect on the stock exchange. Thus, it is possible to conclude that irrational decisions may have strong impact on the pricing of stocks on the capital market. The momentum effect persisted throughout the entire analyzed period, although its power changed cyclically, which coincides with results of research carried out in other countries. The fact that the momentum effect did not disappear may suggest that the factors involved in its creation are an indispensable part of the market, and this seems to undermine the commonly accepted

    Full Text Available Trees remove air pollution by the interception of particulate matter on plant surfaces and the absorption of gaseous pollutants through leaf stomata. However, to date, we have rather few empirical studies on the magnitude and value of the effects of trees on air quality and human health, especially especially within the climatic conditions of Central Europe. To investigate the significance of urban trees from the point of view of air pollution removal, an i-Tree Eco model was implemented. The results indicate that the 932 trees in Krasiński Gardens (Warsaw, Poland absorb 267.12 kg of pollutants per year: 149.9 kg of O3, 94.4 kg of NO2, 11.8 kg of SO2 and 10.9 kg of PM2.5. That makes an average removal per tree (calculated by summarizing the values of all of the pollutants of 0.287 kg/year. Furthermore, health values were used to estimate their pollution removal services in monetary terms. The total benefit of air purification by trees in Krasiński Gardens is estimated at 26250 PLN/year with an average value per tree of: 28 PLN. Although PM2.5 removal is the lowest among the four air pollutants analysed, accounting for only 4% of the total mass reduction, it provides 69% of the total economic value. The benefit associated with absorption of O3 provided 28% of the value, with the absorption of NO2 and SO2 at just 3%. The results also show that large tree species (with a crown diameter of 14-15m can provide around 10 times higher benefits, than small ones (5-6m.

    Understanding the Coriolis effect is essential for explaining the movement of air masses and ocean currents. The lesson we propose aims to familiarize students with the manifestation of the Coriolis effect. Students are guided to build, using the GeoGebra software, a simulation of the motion of a body, related to a rotating reference system. The mathematical expression of the Coriolis force is deduced, for particular cases, and the Foucault's pendulum is presented and explained. Students have the opportunity to deepen the subject, by developing materials related to topics such as: • Global Wind Pattern • Ocean Currents • Coriolis Effect in Long Range Shooting • Finding the latitude with a Foucault Pendulum

    Astronomers have compiled evidence that what we always thought of as the actual universe- all the planets, stars, galaxies and matter in space -represents a mere 4% of what's out there. The rest is dark: 23% is called dark matter, 73% dark energy. Scientists have ideas about what dark matter is, but hardly any understanding about dark energy. This has led to rethinking traditional physics and cosmology. Assuming the existence of dark matter and that the law of gravitation is universal, two teams of astrophysicists, from Lawrence Berkeley National Laboratory and the Australian National University, analysed the universe's growth and to their surprise both concluded that the universe expansion is not slowing but speeding up. If the dominant force of evolution isn't gravity what is it?

    Full Text Available This contribution focuses on the transport of passengers on international routes and the legal regime set down by the Warsaw Convention of 1929 and reinforced by the Montréal Convention of 1999. These Conventions regulate commercial aviation by detailing a set of minimum standardised procedures for flight safety, such as standards for air navigation systems, amongst others, to ensure safe and efficient air travel. The legal regime also regulates the possible claims that may be made against airlines for the death of or harm to passengers, as well as relating to damage to and loss of baggage. The regime not only limits claims temporally and by location, but it also excludes the application of national legal regimes. With regard to claims of harm to dignity the regime disallows such claims to be brought within the restrictions placed by the legal regimes or on any other basis. The contribution does not address the full coverage of these Conventions, only the exclusion of mental / emotional injuries. The Convention excludes emotional harm from the definition of death and physical harm. However claimants have brought claims to undermine the main exclusion of claims with regard to compensation for emotional harm. This contribution explores the exclusion of claims in the Warsaw and Montréal Conventions and thereafter analyses two court decisions in common law countries where this exclusion of claims was challenged and the challenge failed.

    Regular physical activity (PA) is associated with numerous physical and psychological health benefits. Adolescents, specifically girls, are at risk of physical inactivity. To date, there is limited research on PA interventions involving peers, which could encourage more adolescent girls to engage in PA. The investigation aimed to evaluate the feasibility of a novel school three-tier peer-led mentoring model designed to improve PA levels and reduce sedentary time (ST) of adolescent girls. Two-hundred and forty-nine Year 9 adolescent girls (13⁻15 years old) from three UK secondary schools were invited to participate in a peer-led mentoring intervention (Girls Peer Activity (G-PACT) project). The peer-led mentoring model was delivered in all three schools. Two of the schools received an additional after-school PA component. PA and ST were assessed through wrist-worn accelerometry. Girls who received an exercise class after-school component significantly increased their whole day moderate-to-vigorous PA (MVPA) (3.2 min, p = 0.009, d = 0.33). Girls who received no after-school component significantly decreased their MVPA (3.5 min, p = 0.016, d = 0.36) and increased their ST (17.2 min, p = 0.006, d = 0.43). The G-PACT intervention demonstrated feasibility of recruitment and data collection procedures for adolescent girls. The peer-led mentoring model shows promise for impacting girls' MVPA levels when combined with an after-school club PA opportunity.

    Between the years 1985 and 1994 at the Maria Sklodowska-Curie Memorial Cancer Center and Institute of Oncology in Warsaw two radiotherapy techniques were used in the case of postmastectomy breast cancer patients. In technique 'A', in order to limit cardiotoxicity, peripheral nodes only were irradiated, in technique 'B' the chest wall was additionally treated. Usually technique 'B' was chosen in more advanced cases, but generally the selection of the technique was left to the discretion of the attending physician.To estimate disease free survival (DFS) and overall survival (OS) with regard to prognostic factors, to evaluate locoregional failures as related to the radiotherapy technique and to assess early and late morbidity. The retrospective analysis included 507 postmastectomy patients consecutively irradiated for breast cancer in stage IA - III B. Median age was 57 years. Median follow-up was 10 years. The incidence of patients with pN1 stage was 90% and with pN0 10%. We applied a total dose of 50 Gy in 25 fractions, over 5 weeks, with Co 60 to the supraclavicular area, axillary and internal mammary nodes. The chest wall was irradiated with electrons to a total dose of 46 Gy at 90% isodose in 23 fractions over 5 weeks. Three-dimensional treatment planning of the chest wall was used. Technique 'A' and 'B' were used in 62% and 38% of patients, respectively. Simultaneously with radiotherapy 67% of patients received chemotherapy (CMF), and/or hormonotherapy (tamoxifen). In 33% of patients no systemic treatment was administered. We analysed the influence of the following prognostic factors: age and hormonal status, additional diseases, duration of symptoms before treatment, breast laterality, T-stage, breast tumour location, carcinoma type, tumour grade, nodal index, extranodal extension and vascular invasion on disease free survival (DFS) and overall survival (OS); in a univariate analysis with the Kaplan-Meier method and in a multivariate analysis with the Cox

    Policy-makers promote a seek, test, treat and retain (STTR) strategy to expand HIV testing, support linkage and engagement in care, and enhance the continuous use of antiretroviral therapy for those HIV-infected. This HIV prevention strategy is particularly appropriate in correctional settings where HIV screening and treatment are routinely available yet many HIV-infected individuals have difficulty sustaining sufficient linkage and engagement in care, disease management, and viral suppression after prison release. Our research team developed Project imPACT (individuals motivated to Participate in Adherence, Care and Treatment), a multi-component approach for HIV-Infected recently incarcerated individuals that specifically targets their care linkage, retention, and medication adherence by addressing multiple barriers to care engagement after release. The ultimate goals of this intervention are to improve the health of HIV-infected individuals recently released from prison and reduce HIV transmission to their communities by maintaining viral suppression. This paper describes the intervention and technology development processes, based on best practices for intervention development and process evaluation. These processes included: 1) identifying the target population; 2) clarifying the theoretical basis for intervention design; 3) describing features of its foundational interventions; 4) conducting formative qualitative research; 5) integrating and adapting foundational interventions to create and refine intervention content based on target audience feedback. These stages along with the final intervention product are described in detail. The intervention is currently being evaluation and a two arm randomized, controlled trial in two US state prison systems. Based on a literature review, qualitative research, integration of proven interventions and behavioral theory, the final imPACT intervention focused on the transition period two to three months before and three

    2010-01-01

    Many textbooks dealing with general relativity do not demonstrate the derivation of forces in enough detail. The analyses presented herein demonstrate straightforward methods for computing forces by way of general relativity. Covariant divergence of the stress-energy-momentum tensor is used to derive a general expression of the force experienced by an observer in general coordinates. The general force is then applied to the local co-moving coordinate system of a uniformly accelerating observer, leading to an expression of the inertial force experienced by the observer. Next, applying the general force in Schwarzschild coordinates is shown to lead to familiar expressions of the gravitational force. As a more complex demonstration, the general force is applied to an observer in Boyer-Lindquist coordinates near a rotating, Kerr black hole. It is then shown that when the angular momentum of the black hole goes to zero, the force on the observer reduces to the force on an observer held stationary in Schwarzschild coordinates. As a final consideration, the force on an observer moving in rotating coordinates is derived. Expressing the force in terms of Christoffel symbols in rotating coordinates leads to familiar expressions of the centrifugal and Coriolis forces on the observer. It is envisioned that the techniques presented herein will be most useful to graduate level students, as well as those undergraduate students having experience with general relativity and tensor analysis.

  6. Malaysia and forced migration

    2012-06-01

    Full Text Available This paper analyzes the phenomenon of “forced migration” in Malaysia. It examines the nature of forced migration, the challenges faced by Malaysia, the policy responses and their impact on the country and upon the forced migrants. It considers forced migration as an event hosting multifaceted issues related and relevant to forced migrants and suggests that Malaysia has been preoccupied with the issue of forced migration movements. This is largely seen in various responses invoked from Malaysia due to “south-south forced migration movements.” These responses are, however, inadequate in terms of commitment to the international refugee regime. While Malaysia did respond to economic and migration challenges, the paper asserts that such efforts are futile if she ignores issues critical to forced migrants.

    2014-01-01

    In this paper, the role of three-nucleon forces in ab initio calculations of nuclear systems is investigated. The difference between genuine and induced many-nucleon forces is emphasized. Induced forces arise in the process of solving the nuclear many-body problem as technical intermediaries toward calculationally converged results. Genuine forces make up the Hamiltonian. They represent the chosen underlying dynamics. The hierarchy of contributions arising from genuine two-, three- and many-nucleon forces is discussed. Signals for the need of the inclusion of genuine three-nucleon forces are studied in nuclear systems, technically best under control, especially in three-nucleon and four-nucleon systems. Genuine three-nucleon forces are important for details in the description of some observables. Their contributions to observables are small on the scale set by two-nucleon forces. (author)

    We present Heisenberg's equation of motion for the radial variable of a free non-relativistic particle in D dimensions. The resulting radial force consists of three contributions: (i) the quantum fictitious force which is either attractive or repulsive depending on the number of dimensions, (ii......) a singular quantum force located at the origin, and (iii) the centrifugal force associated with non-vanishing angular momentum. Moreover, we use Heisenberg's uncertainty relation to introduce a lower bound for the kinetic energy of an ensemble of neutral particles. This bound is quadratic in the number...... of atoms and can be traced back to the repulsive quantum fictitious potential. All three forces arise for a free particle: "Force without force"....

    2012-11-01

    Diagnostics imaging is an essential component of patient selection and treatment planning in oral rehabilitation by means of osseointegrated implants. In 2002, the EAO produced and published guidelines on the use of diagnostic imaging in implant dentistry. Since that time, there have been significant developments in both the application of cone beam computed tomography as well as in the range of surgical and prosthetic applications that can potentially benefit from its use. However, medical exposure to ionizing radiation must always be justified and result in a net benefit to the patient. The as low a dose as is reasonably achievable principle must also be applied taking into account any alternative techniques that might achieve the same objectives. This paper reports on current EAO recommendations arising from a consensus meeting held at the Medical University of Warsaw (2011) to update these guidelines. Radiological considerations are detailed, including justification and optimization, with a special emphasis on the obligations that arise for those who prescribe or undertake such investigations. The paper pays special attention to clinical indications and radiographic diagnostic considerations as well as to future developments and trends.

    In a two-dimensional world, a free quantum particle of vanishing angular momentum experiences an attractive force. This force originates from a modification of the classical centrifugal force due to the wave nature of the particle. For positive energies the quantum anticentrifugal force manifests itself in a bunching of the nodes of the energy wave functions towards the origin. For negative energies this force is sufficient to create a bound state in a two-dimensional δ-function potential. In a counterintuitive way, the attractive force pushes the particle away from the location of the δ-function potential. As a consequence, the particle is localized in a band-shaped domain around the origin

  18. Relativistic Linear Restoring Force

    2012-01-01

    We consider two different forms for a relativistic version of a linear restoring force. The pair comes from taking Hooke's law to be the force appearing on the right-hand side of the relativistic expressions: d"p"/d"t" or d"p"/d["tau"]. Either formulation recovers Hooke's law in the non-relativistic limit. In addition to these two forces, we…

    This paper presents a theoretical and experimental investigation of a new kind of force sensor which detects forces by measuring an induced pressure change in a material of large Poisson's ratio. In this investigation we develop mathematical expressions for the sensor's sensitivity and bandwidth, and show that its sensitivity can be much larger and its bandwidth is usually smaller than those of existing strain-gage-type sensors. This force sensor is well-suited for measuring large but slowly varying forces. It can be installed in a space smaller than that required by existing sensors

    When pulled along the axis, double-strand DNA undergoes a large conformational change and elongates by roughly twice its initial contour length at a pulling force of about 70 pN. The transition to this highly overstretched form of DNA is very cooperative. Applying a force perpendicular to the DNA axis (unzipping), double-strand DNA can also be separated into two single-stranded DNA, this being a fundamental process in DNA replication. We study the DNA overstretching and unzipping transition using fully atomistic molecular dynamics (MD) simulations and argue that the conformational changes of double-strand DNA associated with either of the above mentioned processes can be viewed as force induced DNA melting. As the force at one end of the DNA is increased the DNA starts melting abruptly/smoothly above a critical force depending on the pulling direction. The critical force f m , at which DNA melts completely decreases as the temperature of the system is increased. The melting force in the case of unzipping is smaller compared to the melting force when the DNA is pulled along the helical axis. In the case of melting through unzipping, the double-strand separation has jumps which correspond to the different energy minima arising due to sequence of different base pairs. The fraction of Watson-Crick base pair hydrogen bond breaking as a function of force does not show smooth and continuous behavior and consists of plateaus followed by sharp jumps.

    1988-01-01

    The Security Exercise Evaluation System (SEES) is under development for use in planning Force on Force exercises and as an aid in post-exercise evaluation. This study is part of the development cycle where the simulation results are compared to field data to provide guidance for further development of the model. SEES is an event-driven stochastic computer program simulating individual movement and combat within an urban terrain environment. The simulator models the physics of movement, line of sight, and weapon effects. It relies on the controllers to provide all knowledge of security tactics, which are entered by the controllers during the simulation using interactive color graphic workstations. They are able to develop, modify and implement plans promptly as the simulator maintains real time. This paper reports on how SEES will be used to develop an intrusion plan, test the security response tactics and develop observer logistics. A Force on Force field exercise will then be executed to follow the plan with observations recorded. An analysis is made by first comparing the plan and events of the simulation with the field exercise, modifying the simulation plan to match the actual field exercise, and then running the simulation to develop a distribution of possible outcomes

    The purpose of this study was to evaluate cable tension during installation, and during loading similar to walking in a cable grip type greater trochanter (GT), reattachment system. A 4th generation Sawbones composite femur with osteotomised GT was reattached with four Cable-Ready® systems (Zimmer, Warsaw, IN). Cables were tightened at 3 different target installation forces (178, 356 and 534 N) and retightened once as recommended by the manufacturer. Cables tension was continuously monitored using in-situ load cells. To simulate walking, a custom frame was used to apply quasi static load on the head of a femoral stem implant (2340 N) and abductor pull (667 N) on the GT. GT displacement (gap and sliding) relative to the femur was measured using a 3D camera system. During installation, a drop in cable tension was observed when tightening subsequent cables: an average 40+12.2% and 11 ± 5.9% tension loss was measured in the first and second cable. Therefore, retightening the cables, as recommended by the manufacturer, is important. During simulated walking, the second cable additionally lost up to 12.2+3.6% of tension. No difference was observed between the GT-femur gaps measured with cables tightened at different installation forces (p=0.32). The GT sliding however was significantly greater (0.9 ± 0.3 mm) when target installation force was set to only 178 N compared to 356 N (0.2 ± 0.1 mm); pcable tightening force should be as close as possible to that recommended by the manufacturer, because reducing it compromises the stability of the GT fragment, whereas increasing it does not improve this stability, but could lead to cable breakage.

Further analysis of the original Eoetvoes experiments has uncovered no challenges to our original assertion that these data evidence a correlation characteristic of the presence of a new coupling to baryon number or hypercharge. Various models suggest that the proposed fifth force could be accomodated naturally into the existing theoretical framework

  10. Ponderomotive Forces in Cosmos

    Science.gov (United States)

    Lundin, R.; Guglielmi, A.

    2006-12-01

    This review is devoted to ponderomotive forces and their importance for the acceleration of charged particles by electromagnetic waves in space plasmas. Ponderomotive forces constitute time-averaged nonlinear forces acting on a media in the presence of oscillating electromagnetic fields. Ponderomotive forces represent a useful analytical tool to describe plasma acceleration. Oscillating electromagnetic fields are also related with dissipative processes, such as heating of particles. Dissipative processes are, however, left outside these discussions. The focus will be entirely on the (conservative) ponderomotive forces acting in space plasmas. The review consists of seven sections. In Section 1, we explain the rational for using the auxiliary ponderomotive forces instead of the fundamental Lorentz force for the study of particle motions in oscillating fields. In Section 2, we present the Abraham, Miller, Lundin-Hultqvist and Barlow ponderomotive forces, and the Bolotovsky-Serov ponderomotive drift. The hydrodynamic, quasi-hydrodynamic, and ‘`test-particle’' approaches are used for the study of ponderomotive wave-particle interaction. The problems of self-consistency and regularization are discussed in Section 3. The model of static balance of forces (Section 4) exemplifies the interplay between thermal, gravitational and ponderomotive forces, but it also introduces a set of useful definitions, dimensionless parameters, etc. We analyze the Alfvén and ion cyclotron waves in static limit with emphasis on the specific distinction between traveling and standing waves. Particular attention has been given to the impact of traveling Alfvén waves on the steady state anabatic wind that blows over the polar regions (Section~5). We demonstrate the existence of a wave-induced cold anabatic wind. We also show that, at a critical point, the ponderomotive acceleration of the wind is a factor of 3 greater than the thermal acceleration. Section 6 demonstrates various

  12. OOTW Force Design Tools

    Energy Technology Data Exchange (ETDEWEB)

    Bell, R.E.; Hartley, D.S.III; Packard, S.L.

    1999-05-01

    This report documents refined requirements for tools to aid the process of force design in Operations Other Than War (OOTWs). It recommends actions for the creation of one tool and work on other tools relating to mission planning. It also identifies the governmental agencies and commands with interests in each tool, from whom should come the user advisory groups overseeing the respective tool development activities. The understanding of OOTWs and their analytical support requirements has matured to the point where action can be taken in three areas: force design, collaborative analysis, and impact analysis. While the nature of the action and the length of time before complete results can be expected depends on the area, in each case the action should begin immediately. Force design for OOTWs is not a technically difficult process. Like force design for combat operations, it is a process of matching the capabilities of forces against the specified and implied tasks of the operation, considering the constraints of logistics, transport and force availabilities. However, there is a critical difference that restricts the usefulness of combat force design tools for OOTWs: the combat tools are built to infer non-combat capability requirements from combat capability requirements and cannot reverse the direction of the inference, as is required for OOTWs. Recently, OOTWs have played a larger role in force assessment, system effectiveness and tradeoff analysis, and concept and doctrine development and analysis. In the first Quadrennial Defense Review (QDR), each of the Services created its own OOTW force design tool. Unfortunately, the tools address different parts of the problem and do not coordinate the use of competing capabilities. These tools satisfied the immediate requirements of the QDR, but do not provide a long-term cost-effective solution.

    The knowledge and acceptance of the concept of brain death among future health professionals is essential. The objective of this study was to analyze the knowledge of the concept of brain death among nursing students at the Medical University of Warsaw and determine the factors that affect it. Academic year 2011-2012, nursing students of the University of Poland. Sampling points in 5 compulsory-attendance nursing courses with a completion rate >80%. Validated questionnaire (PCID-DTO Rios), anonymous and self-administered. The completion rate was 96% (793/828); 71% (n = 561) knew the concept of brain death, 22% (n = 178) did not know it, and 7% (n = 54) did not know that it implies the death of the patient. Variables related to the correct knowledge: 1) to be studying in 4th year compared with 1st year (85% vs 60%; P ≤ .001); 2) discuss the subject with family (76% vs 61%; P ≤ .001); 3) discuss with friends (73% vs 63%; P = .009); and 4) having a favorable attitude toward organ donation (74% vs 65%; P = .011). In the multivariate analysis, the variables that remained independent were studying in 4th year (odds ratio [OR], 3.809; 95% confidence interval [CI], 2.006-5.823; P ≤ .001) and discussed with family concerning donation and transplantation (OR, 1.718; 95% CI, 1.241-2.381; P ≤ .001). One-third of the nursing students were unfamiliar with the concept of brain death. Copyright © 2016 Elsevier Inc. All rights reserved.

    This is a tutorial-style selective review explaining basic concepts of forced magnetic reconnection. It is based on a celebrated model of forced reconnection suggested by J. B. Taylor. The standard magnetohydrodynamic (MHD) theory of this process has been pioneered by Hahm & Kulsrud (Phys. Fluids, vol. 28, 1985, p. 2412). Here we also discuss several more recent developments related to this problem. These include energetics of forced reconnection, its Hall-mediated regime, and nonlinear effects with the associated onset of the secondary tearing (plasmoid) instability.

    Virus-specific T-cells (VSTs) proliferate exponentially after adoptive transfer into hematopoietic stem cell transplant (HSCT) recipients, eliminate virus infections, then persist and provide long-term protection from viral disease. If VSTs behaved similarly when modified with tumor-specific chimeric antigen receptors (CARs), they should have potent anti-tumor activity. This theory was evaluated by Cruz et al. in a previous clinical trial with CD19.CAR-modified VSTs, but there was little apparent expansion of these cells in patients. In that study, VSTs were gene-modified on day 19 of culture and we hypothesized that by this time, sufficient T-cell differentiation may have occurred to limit the subsequent proliferative capacity of the transduced T-cells. To facilitate the clinical testing of this hypothesis in a project supported by the NHLBI-PACT mechanism, we developed and optimized a good manufacturing practices (GMP) compliant method for the early transduction of VSTs directed to Epstein-Barr virus (EBV), Adenovirus (AdV) and cytomegalovirus (CMV) using a CAR directed to the tumor-associated antigen disialoganglioside (GD2). Ad-CMVpp65-transduced EBV-LCLs effectively stimulated VSTs directed to all three viruses (triVSTs). Transduction efficiency on day three was increased in the presence of cytokines and high-speed centrifugation of retroviral supernatant onto retronectin-coated plates, so that under optimal conditions up to 88% of tetramer-positive VSTs expressed the GD2.CAR. The average transduction efficiency of early-and late transduced VSTs was 55 ± 4% and 22 ± 5% respectively, and early-transduced VSTs maintained higher frequencies of T cells with central memory or intermediate memory phenotypes. Early-transduced VSTs also had higher proliferative capacity and produced higher levels of TH1 cytokines IL-2, TNF-α, IFN-γ, MIP-1α, MIP-1β and other cytokines in vitro. We developed a rapid and GMP compliant method for the early transduction of

    1994-01-01

    One of the issues facing valve maintenance personnel today deals with an appropriate methodology for installing and setting valve packing that will minimize leak rates, yet ensure functionality of the the valve under all anticipated operating conditions. Several variables can affect a valve packing's ability to seal, such as packing bolt torque, stem finish, and lubrication. Stem frictional force can be an excellent overall indicator of some of the underlying conditions that affect the sealing characteristics of the packing and the best parameter to use when adjusting the packing. This paper addresses stem friction forces, analytically derives the equations related to these forces, presents a methodology for measuring these forces on valve stems, and attempts to correlate the data directly to the underlying variables

    1992-01-01

    This paper reports that the structure of the post-World War II European security system has been transformed by the remarkable events of 1989 and 1990. These changes included the collapse of the communist parties in Eastern Europe, which has led to the disintegration of the Warsaw Pact. Simultaneously, the prospect of German reunification accelerated during the winter of 1990 and was sanctioned in the dramatic Kohl-Gorbachev July 1990 summit in the Soviet Union. During that meeting, the Soviet government made a series of politically contentious concessions and accepted that a united Germany could remain in NATO, albeit with some unilateral restrictions on the size of the new German armed forces and the disposition of non-German NATO forces in the former German Democratic Republic (GDR). The acceptance by Mikhail Gorbachev and his regime of an end to the cold war on terms very favorable to the West followed two important meetings. The first was the London NATO summit; the Atlantic Alliance announced a major change of its flexible response strategy in which nuclear weapons would be used as a last resort. Further, the alliance called for a series of bilateral nonaggression agreements with the former members of the Warsaw Pact including the Soviet Union. The second meeting, the 28th Party Congress of the Communist Party of the Soviet Union (CPSU), concluded with a major political victory by Gorbachev over his hard line opponents both in the civilian apparatus and the military. The final barrier to German unification, on October 3, 1990, fell when the new German government formally acknowledged the Oder-Neisse boundary as unalterable in a treaty signed by the members of the 2 + 4 Talks on September 12, 1990, in Moscow. Most important from the perspective of NATO is the commitment by the Soviet Union to totally withdraw all of its air and ground units from the former GDR by 1994

Based on an extensive review of relevant theory and empirical work in strategic decision-making, organizational change theory, cognitive and social psychology, and strategy processes, seven kinds of ''forces'' - rational, imposed, teleological, learning, political, heuristic, and social...... - are identified as interacting in and having significant influence on the strategy formation process. It is further argued that by applying a holistic ''forces-view'' of the significant and interacting influences on strategy formation, we can better understand the dynamics and challenges in managing the process...

    2007-01-01

    High-quality pediatric palliative care should be an expected standard in the United States, especially since the publication of the numerous position statements such as "Precepts of Palliative Care for Children and Adolescents and Their Families," a joint statement created by the Association of Pediatric Oncology Nurses, the National Association of Neonatal Nurses, and the Society of Pediatric Nurses. Although many barriers still exist, dedicated individuals and teams strive to promote models of excellence and improve care for children with life-threatening conditions and their families. The Pediatric Advanced Care Team, a joint project of Dana-Farber Cancer Institute and Children's Hospital, Boston, is one such interdisciplinary pediatric palliative care consultation service. Founded in 1997, we have grown and learned from formal study and our extensive clinical work with families, children, and our colleagues. This article describes our journey as an interdisciplinary team forging a new service within two renowned medical institutions in which historically the primary emphasis of care has been on cure and innovation. Although these values remain, our work has resulted in an increased acceptance of balancing treatment of the underlying disease or condition along with treatment of the physical, psychosocial, and spiritual needs of the child and family through life or death. One of our goals is to help promote a balance of hope for cure with hope for comfort, dignity, and integrity for every child and family.

    A system and method for electrochemical force microscopy are provided. The system and method are based on a multidimensional detection scheme that is sensitive to forces experienced by a biased electrode in a solution. The multidimensional approach allows separation of fast processes, such as double layer charging, and charge relaxation, and slow processes, such as diffusion and faradaic reactions, as well as capturing the bias dependence of the response. The time-resolved and bias measurements can also allow probing both linear (small bias range) and non-linear (large bias range) electrochemical regimes and potentially the de-convolution of charge dynamics and diffusion processes from steric effects and electrochemical reactivity.

    The marginal adaptation of full coverage restorations is adversely affected by the introduction of luting agents of various minimum film thicknesses during the cementation process. The increase in the marginal opening may have long-term detrimental effects on the health of both pulpal and periodontal tissues. The purpose of this study was to determine the effects of varying seating forces (2.5, 12.5, 25 N), venting, and cement types on post-cementation marginal elevation in cast crowns. A standardized cement space of 40 microns was provided between a machined gold crown and a stainless steel die. An occlusal vent was placed that could be opened or closed. The post-cementation crown elevation was measured, following the use of two commercially available capsulated dental cements (Phosphacap, and Ketac-cem Applicap). The results indicate that only the combination of Ketac-Cem Applicap and crown venting produced post-cementation crown elevation of less than 20 microns when 12.5 N seating force was used. Higher forces (25 N) and venting were required for comparable seating when using Phosphacap (19 microns). The amount of force required to allow maximum seating of cast crowns appears to be cement specific, and is reduced by effective venting procedures.

    Measuring vital physiological pressures is important for monitoring health status, preventing the buildup of dangerous internal forces in impaired organs, and enabling novel approaches of using mechanical stimulation for tissue regeneration. Pressure sensors are often required to be implanted and directly integrated with native soft biological systems. Therefore, the devices should be flexible and at the same time biodegradable to avoid invasive removal surgery that can damage directly interfaced tissues. Despite recent achievements in degradable electronic devices, there is still a tremendous need to develop a force sensor which only relies on safe medical materials and requires no complex fabrication process to provide accurate information on important biophysiological forces. Here, we present a strategy for material processing, electromechanical analysis, device fabrication, and assessment of a piezoelectric Poly-l-lactide (PLLA) polymer to create a biodegradable, biocompatible piezoelectric force sensor, which only employs medical materials used commonly in Food and Drug Administration-approved implants, for the monitoring of biological forces. We show the sensor can precisely measure pressures in a wide range of 0-18 kPa and sustain a reliable performance for a period of 4 d in an aqueous environment. We also demonstrate this PLLA piezoelectric sensor can be implanted inside the abdominal cavity of a mouse to monitor the pressure of diaphragmatic contraction. This piezoelectric sensor offers an appealing alternative to present biodegradable electronic devices for the monitoring of intraorgan pressures. The sensor can be integrated with tissues and organs, forming self-sensing bionic systems to enable many exciting applications in regenerative medicine, drug delivery, and medical devices.

    Sinusoidal force calibration method was studied several years before at Physikalisch-Technische Bundesanstalt (PTB). A similar dynamic force calibration system is developed at Changcheng Institute of Metrology and Measurement (CIMM). It uses electro-dynamic shakers to generate dynamic force in the range from 1 N to 20 kN, and heterodyne laser interferometers are used for acceleration measurement. The force transducer to be calibrated is mounted on the shaker, and a mass block is screwed on the top of force transducer, the sinusoidal forces realized by accelerated load masses are traceable to acceleration and mass according to the force definition. The methods of determining Spatial-dependent acceleration on mass block and measuring the end mass of force transducer in dynamic force calibration are discussed in this paper.

  1. Casimir forces and geometry

    International Nuclear Information System (INIS)

    Buescher, R.

    2005-01-01

    Casimir interactions are interactions induced by quantum vacuum fluctuations and thermal fluctuations of the electromagnetic field. Using a path integral quantization for the gauge field, an effective Gaussian action will be derived which is the starting point to compute Casimir forces between macroscopic objects analytically and numerically. No assumptions about the independence of the material and shape dependent contributions to the interaction are made. We study the limit of flat surfaces in further detail and obtain a concise derivation of Lifshitz' theory of molecular forces. For the case of ideally conducting boundaries, the Gaussian action will be calculated explicitly. Both limiting cases are also discussed within the framework of a scalar field quantization approach, which is applicable for translationally invariant geometries. We develop a non-perturbative approach to calculate the Casimir interaction from the Gaussian action for periodically deformed and ideally conducting objects numerically. The obtained results reveal two different scaling regimes for the Casimir force as a function of the distance between the objects, their deformation wavelength and -amplitude. The results confirm that the interaction is non-additive, especially in the presence of strong geometric deformations. Furthermore, the numerical approach is extended to calculate lateral Casimir forces. The results are consistent with the results of the proximity-force approximation for large deformation wavelengths. A qualitatively different behaviour between the normal and lateral force is revealed. We also establish a relation between the boundary induced change of the of the density of states for the scalar Helmholtz equation and the Casimir interaction using the path integral method. For statically deformed boundaries, this relation can be expressed as a novel trace formula, which is formally similar to the so-called Krein-Friedel-Lloyd formula. While the latter formula describes the

    Single-molecule force spectroscopy is a powerful technique for addressing single molecules. Unseen structures and dynamics of molecules have been elucidated using force spectroscopy. Atomic force microscope (AFM)-based force spectroscopy studies have provided picoNewton force resolution, subnanometer spatial resolution, stiffness of substrates, elasticity of polymers, and thermodynamics and kinetics of single-molecular interactions. In addition, AFM has enabled mapping the distribution of individual molecules in situ, and the quantification of single molecules has been made possible without modification or labeling. In this review, we describe the basic principles, sample preparation, data analysis, and applications of AFM-based force spectroscopy and its future.

    Many metal parts manufacturers use large metal presses to shape sheet metal into finished products like car body parts, jet wing and fuselage surfaces, etc. These metal presses take sheet metal and - with enormous force - reshape the metal into a fully formed part in a manner of seconds. Although highly efficient, the forces involved in forming metal parts also damage the press itself, limit the metals used in part production, slow press operations and, when not properly controlled, cause the manufacture of large volumes of defective metal parts. To date, the metal-forming industry has not been able to develop a metal-holding technology that allows full control of press forces during the part forming process. This is of particular importance in the automotive lightweighting efforts under way in the US automotive manufacturing marketplace. Metalforming Controls Technology Inc. (MC2) has developed a patented press control system called the Force Modulator that has the ability to control these press forces, allowing a breakthrough in stamping process control. The technology includes a series of hydraulic cylinders that provide controlled tonnage at all points in the forming process. At the same time, the unique cylinder design allows for the generation of very high levels of clamping forces (very high tonnages) in very small spaces; a requirement for forming medium and large panels out of HSS and AHSS. Successful production application of these systems testing at multiple stamping operations - including Ford and Chrysler - has validated the capabilities and economic benefits of the system. Although this technology has been adopted in a number of stamping operations, one of the primary barriers to faster adoption and application of this technology in HSS projects is system cost. The cost issue has surfaced because the systems currently in use are built for each individual die as a custom application, thus driving higher tooling costs. This project proposed to better

    We introduce a linguistic framework through which one can interpret systematically students’ understanding of and reasoning about force and motion. Some researchers have suggested that students have robust misconceptions or alternative frameworks grounded in everyday experience. Others have pointed out the inconsistency of students’ responses and presented a phenomenological explanation for what is observed, namely, knowledge in pieces. We wish to present a view that builds on and unifies aspects of this prior research. Our argument is that many students’ difficulties with force and motion are primarily due to a combination of linguistic and ontological difficulties. It is possible that students are primarily engaged in trying to define and categorize the meaning of the term “force” as spoken about by physicists. We found that this process of negotiation of meaning is remarkably similar to that engaged in by physicists in history. In this paper we will describe a study of the historical record that reveals an analogous process of meaning negotiation, spanning multiple centuries. Using methods from cognitive linguistics and systemic functional grammar, we will present an analysis of the force and motion literature, focusing on prior studies with interview data. We will then discuss the implications of our findings for physics instruction.

    This paper focuses on the unique aspects of the Fernald Citizens Task Force process that have contributed to a largely successful public participation effort at Fernald. The Fernald Citizens Task Force passed quickly by many procedural issues. Instead, the Task Force concentrated on (a) educating itself about the site, its problems, and possible solutions, and (b) choosing a directed way to approach its mandate: To make recommendations on several open-quotes big pictureclose quotes issues, including future use of the site, cleanup levels, waste disposition, and cleanup priorities. This paper presents the approach used at Fernald for establishing and running a focused site-specific advisory board, the key issues that have been faced, and how these issues were resolved. The success of Fernald in establishing a strong and functioning site-specific advisory board serves as a useful model for other DOE facilities, although the Fernald model is just one of many approaches that can be taken. However, the approach presented here has worked extremely well for Fernald

    One of the more congested areas in the ATLAS detector is the GAP region (the area between the Barrel Calorimeter and the End Cap calorimeter) where Inner Detector services, LAr Services and some Tile services all must co-habitat in a very limited area. It has been clear for some time that the space in the GAP region is not sufficient to accommodate all that is needed. In the last few month additional problems of routing all the services to Z=0 have been encountered due to the very limited space between the Tile Calorimeter and the first layer of Muon chambers. The Technical Management Board (TMB) and the Executive Board (EB) decided in the middle of March to establish a Task Force to look at this problem and come up with a solution within well-specified guidelines. The task force consisted of experts from the ID, Muon, Liquid Argon and Tile systems in addition to experts from the Technical Coordination team and the Physics coordinator. The task force held many meetings and in general there were some very l...

    In epithelial tissues, cells constantly generate and transmit forces between each other. Forces generated by the actomyosin cytoskeleton regulate tissue shape and structure and also provide signals that influence cells' decisions to divide, die, or differentiate. Forces are transmitted across epithelia because cells are mechanically linked through junctional complexes, and forces can propagate through the cell cytoplasm. Here, we review some of the molecular mechanisms responsible for force generation, with a specific focus on the actomyosin cortex and adherens junctions. We then discuss evidence for how these mechanisms promote cell shape changes and force transmission in tissues. © 2016 Wiley Periodicals, Inc.

    Full Text Available Force Dynamics of Verb Complementation The concepts of motion and force are both extensively discussed in cognitive linguistics literature. But they are discussed separately. The first usually in the context of ‘motion situations’ (Talmy, Slobin, Zlatev, the other as part of the Force Dynamics framework, which was developed by Talmy. The aim of this paper is twofold: first, to argue that the concepts of force and motion should not be isolated but considered as two inseparable parts of force-motion events. The second goal is to prove that the modified Force Dynamics (force-motion framework can be used for precise characterization of the verb complementation patterns. To this end, a random sample of 50 sentences containing the verb ‘went’ is analyzed, demonstrating the differences between the categories of intensive and intransitive complementation with respect to the linguistically coded parameters of force and motion.

    The Atomic Force Microscope (AFM) is a recently developed instrument that has achieved atomic resolution imaging of both conducting and non- conducting surfaces. Because the AFM is in the early stages of development, and because of the difficulty of building the instrument, it is currently in use in fewer than ten laboratories worldwide. It promises to be a valuable tool for obtaining information about engineering surfaces and aiding the .study of precision fabrication processes. This paper gives an overview of AFM technology and presents plans to build an instrument designed to look at engineering surfaces.

  20. TRIGA forced shutdowns analysis

    Negut, Gheorghe; Laslau, Florica

    2008-01-01

    The need for improving the operation leads us to use new methods and strategies. Probabilistic safety assessments and statistical analysis provide insights useful for our reactor operation. This paper is dedicated to analysis of the forced shutdowns during the first reactor operation period, between 1980 to 1989. A forced shutdown data base was designed using data on forced shutdowns collected from the reactor operation logbooks. In order to sort out the forced shutdowns the records have the following fields: - current number, date, equipment failed, failure type (M for mechanical, E for electrical, D for irradiation device, U for human factor failure; - scram mode, SE for external scram, failure of reactor cooling circuits and/or irradiation devices, SR for reactor scram, exceeding of reactor nuclear parameters, SB for reactor scram by control rod drop, SM for manual scram required by the abnormal reactor status; - scram cause, giving more information on the forced shutdown. This data base was processed using DBase III. The data processing techniques are presented. To sort out the data, one of the criteria was the number of scrams per year, failure type, scram mode, etc. There are presented yearly scrams, total operation time in hours, total unavailable time, median unavailable time period, reactor availability A. There are given the formulae used to calculate the reactor operational parameters. There are shown the scrams per year in the 1980 to 1989 period, the reactor operation time per year, the reactor shutdown time per year and the operating time versus down time per year. Total number of scrams in the covered period was 643 which caused a reactor down time of 4282.25 hours. In a table the scrams as sorted on the failure type is shown. Summarising, this study emphasized some problems and difficulties which occurred during the TRIGA reactor operation at Pitesti. One main difficulty in creating this data base was the unstandardized scram record mode. Some times

    We consider theoretical motivations to search for extra short-range fundamental forces as well as experiments constraining their parameters. The forces could be of two types: 1) spin-independent forces; 2) spin-dependent axion-like forces. Different experimental techniques are sensitive in respective ranges of characteristic distances. The techniques include measurements of gravity at short distances, searches for extra interactions on top of the Casimir force, precision atomic and neutron experiments. We focus on neutron constraints, thus the range of characteristic distances considered here corresponds to the range accessible for neutron experiments

    This paper presents a method for differential magnetic force microscope imaging based on a two-pass scanning procedure to extract differential magnetic forces and eliminate or significantly reduce background forces with reversed tip magnetization. In the work, the difference of two scanned images with reversed tip magnetization was used to express the local magnetic forces. The magnetic sample was first scanned with a low lift distance between the MFM tip and the sample surface, and the magnetization direction of the probe was then changed after the first scan to perform the second scan. The differential magnetic force image was obtained through the subtraction of the two images from the two scans. The theoretical and experimental results have shown that the proposed method for differential magnetic force microscope imaging is able to reduce the effect of background or environment interference forces, and offers an improved image contrast and signal to noise ratio (SNR). © Wiley Periodicals, Inc.

  3. Chin force in violin playing.

    Obata, Satoshi; Kinoshita, Hiroshi

    2012-06-01

    Force generated between the left mandible of violinists and the chinrest of the violin was examined using a force-sensing chinrest developed in this study. A strain-gauge force sensor was built, and it was fixed between the violin's top plate and a chin cup. Fifteen professional/amateur violinists held the violin statically, played musical scales with different sound properties and sounding techniques, as well as an excerpt from a Max Bruch concerto. Peak and mean forces were evaluated for each task. In a separate experiment, lateral movement of the lower teeth due to different levels of voluntary chin force exertion was measured. Static holding forces observed were 15 and 22 N with and without the help of the left hand, respectively. Peak force increased from 16 N at soft dynamics to 20 N at strong dynamics during scales. The force further increased to 29 N with the use of vibrato technique and 35 N during shifts. Tempo and hand position did not affect the force. Playing a Bruch concerto induced a mean peak force of 52 N, ranging from 31 to 82 N among the violinists. The developed force-sensing chinrest could accurately record the generated chin force. Typical chin force to stabilize the violin during ordinary musical performance was less than 30 N, but it could momentarily exceed 50 N when technically demanding musical pieces were performed. The lateral shift of the mandible was fairly small (<0.4 mm) even with high chin-force exertion, possibly due to clenching of the molars.

  4. [Galileo and centrifugal force].

    Science.gov (United States)

    Vilain, Christiane

    This work intends to focus on Galileo's study of what is now called "centrifugal force," within the framework of the Second Day of his Dialogo written in 1632, rather than on the previously published commentaries on the topic. Galileo proposes three geometrical demonstrations in order to prove that gravity will always overcome centrifugalforce, and that the potential rotation of the Earth, whatever its speed, cannot in any case project objects beyond it. Each of these demonstrations must consequently contain an error and it has seemed to us that the first one had not been understood up until now. Our analysis offers an opportunity to return to Galileo's geometrical representation of dynamical questions; actually, we get an insight into the sophistication of Galileo's practices more than into his mistakes. Our second point, concerning the historiography of the problem, shows an evolution from anachronic critics to more contextual considerations, in the course of the second half of the twentieth century.

  5. Force Limit System

    Pawlik, Ralph; Krause, David; Bremenour, Frank

    2011-01-01

    The Force Limit System (FLS) was developed to protect test specimens from inadvertent overload. The load limit value is fully adjustable by the operator and works independently of the test system control as a mechanical (non-electrical) device. When a test specimen is loaded via an electromechanical or hydraulic test system, a chance of an overload condition exists. An overload applied to a specimen could result in irreparable damage to the specimen and/or fixturing. The FLS restricts the maximum load that an actuator can apply to a test specimen. When testing limited-run test articles or using very expensive fixtures, the use of such a device is highly recommended. Test setups typically use electronic peak protection, which can be the source of overload due to malfunctioning components or the inability to react quickly enough to load spikes. The FLS works independently of the electronic overload protection.

    Many people of today have an oppositional attitude towards the continual loss of sense of existence which manifests itself in 'the great refusal'. They also behave in an anti-authoritarian manner towards their first father Marx. They realize that it is ourselves who have to search and find. The protest groups of the most different origin have come into being as 'the sand in the wheels' of a seemingly irresistable force. They have formed themselves beyond the 'Left' and the 'Right'. Nuclear energy is the instrument which acts as a gear for their opposition, which establishes it and which provides the basis for their self-concept. It is the symbol where the conflict between living standard and living quality breaks open. In essential, however, the protest is growing towards supporting an effective administration of all goods of our world. (orig./HP) [de

  7. Students' conceptions about force

    2005-01-01

    Students from a young age have developed in their own minds differing concepts of things such as all creatures having a soul. Also children see the environment and interpret what they see according to their own understanding and explanation. In particular, with regards to physics, things like light, heat, motion, structure of matter and energy are understood at the level of a child s comprehension. Most often the child s understanding varies quite differently from the actual true meaning. As a result the child is reluctant to accept any other explanation. In such situations the necessary difficulties must be tackled with care and caution pertinent to the individual. Studies at K.S.U University related to force and motion of various departments in the Faculty of Science and Letters have been investigated. After evaluations of all the findings a number of suggestions have been made to change student views and ideas

    Detailed description of intermolecular forces is key to understanding a wide range of phenomena from molecular recognition to materials failure. The unique features of atomic force microscopy (AFM) to make point contact force measurements with ultra high sensitivity and to generate spatial maps of surface topography and forces have been extended to include measurements between well-defined organic molecular groups. Chemical modification of AFM probes with self-assembled monolayers (SAMs) was used to make them sensitive to specific molecular interactions. This novel chemical force microscopy (CFM) technique was used to probe forces between different molecular groups in a range of environments (vacuum, organic liquids and aqueous solutions); measure surface energetics on a nanometer scale; determine pK values of the surface acid and base groups; measure forces to stretch and unbind a short synthetic DNA duplex and map the spatial distribution of specific functional groups and their ionization state. Studies of adhesion forces demonstrated the important contribution of hydrogen bonding to interactions between simple organic functionalities. The chemical identity of the tip and substrate surfaces as well as the medium had a dramatic effect on adhesion between model monolayers. A direct correlation between surface free energy and adhesion forces was established. The adhesion between epoxy polymer and model mixed SAMs varied with the amount of hydrogen bonding component in the monolayers. A consistent interpretation of CFM measurements in polar solvents was provided by contact mechanics models and intermolecular force components theory. Forces between tips and surfaces functionalized with SAMs terminating in acid or base groups depended on their ionization state. A novel method of force titration was introduced for highly local characterization of the pK's of surface functional groups. The pH-dependent changes in friction forces were exploited to map spatially the

    Abstract 1. Introduction and aim Ultraviolet radiation is present in the daily life of every human being. The constantly growing number of new cases of skin cancer in Poland and in the world can suggest a lack of adequate knowledge of photoprotection. Raising public awareness, especially among young people about the health effects of excessive UV radiation use, plays a key role in relation to their current and future health. The aim of the study was to assess the level of knowledge among high school students in Warsaw about the health effects resulting from excessive use of ultraviolet radiation, as well as knowledge concerning health behaviors of young people using UV radiation. 2. Material and methods The study group consists of 153 students from Warsaw high schools. The gender distribution was random, the age range of the respondents was 17 to 19 years. The study was conducted using paper questionnaire, consisting of 29 questions. To examine the relationship between the selected traits has been applied test of independence chi-square (χ2 (STATISTICA12 package. In tests the level of significance was p≤0.05. Depending on the size used appropriate amendments to the chi-square test. 3. Results and conclusions There was no relationship between such features as: the use of tanning devices and perception of skin burns as a carcinogenic factor, the use of the solarium and regularly reviewing pigmented moles, the occurrence of malignant melanoma of the skin in the past in the family and the use of tanning devices, the occurrence of skin burns and frequency of use of formulations with UV protection. This may indicate incomplete knowledge of the respondents in terms of the impact of UV on human health.

  10. Corrected direct force balance method for atomic force microscopy lateral force calibration

    International Nuclear Information System (INIS)

    Asay, David B.; Hsiao, Erik; Kim, Seong H.

    2009-01-01

    This paper reports corrections and improvements of the previously reported direct force balance method (DFBM) developed for lateral calibration of atomic force microscopy. The DFBM method employs the lateral force signal obtained during a force-distance measurement on a sloped surface and relates this signal to the applied load and the slope of the surface to determine the lateral calibration factor. In the original publication [Rev. Sci. Instrum. 77, 043903 (2006)], the tip-substrate contact was assumed to be pinned at the point of contact, i.e., no slip along the slope. In control experiments, the tip was found to slide along the slope during force-distance curve measurement. This paper presents the correct force balance for lateral force calibration.

    Atomic Force Microscopy (AFM) is widely used in physics, chemistry, and biology to analyze the topography of a sample at nanometer resolution. Controlling precisely the force applied by the AFM tip to the sample is a prerequisite for faithful and reproducible imaging. In amplitude modulation (oscillating) mode AFM, the applied force depends on the free and the setpoint amplitudes of the cantilever oscillation. Therefore, for keeping the applied force constant, not only the setpoint amplitude but also the free amplitude must be kept constant. While the AFM user defines the setpoint amplitude, the free amplitude is typically subject to uncontrollable drift, and hence, unfortunately, the real applied force is permanently drifting during an experiment. This is particularly harmful in biological sciences where increased force destroys the soft biological matter. Here, we have developed a strategy and an electronic circuit that analyzes permanently the free amplitude of oscillation and readjusts the excitation to maintain the free amplitude constant. As a consequence, the real applied force is permanently and automatically controlled with picoNewton precision. With this circuit associated to a high-speed AFM, we illustrate the power of the development through imaging over long-duration and at various forces. The development is applicable for all AFMs and will widen the applicability of AFM to a larger range of samples and to a larger range of (non-specialist) users. Furthermore, from controlled force imaging experiments, the interaction strength between biomolecules can be analyzed.

We also suggest that gravity and dark energy are types of quantum entanglement forces, similar to Verlinde's entropic force, and give holographic dark energy with an equation of state comparable to current observational data. This connection between quantum entanglement and gravity could give some new in...

  15. Special event launches new partnership. IAEA and NFCR join forces to fight cancer in developing world

    2007-01-01

    Full text: IAEA Director General and Nobel Laureate Mohamed ElBaradei will join more than 100 leading public figures, philanthropists and cancer experts at the United Nations Headquarters in New York on 29 October to mark the launch of a new partnership between the IAEA and the US based National Foundation for Cancer Research (NFCR). Through this partnership, and the endowment fund called the PACT Fund at NFCR, Americans can support the IAEA and its partners in helping poor countries to combat the looming cancer epidemic. 'The IAEA has long provided radiotherapy machines and expertise to developing countries, but the growing cancer crisis cannot be fought with radiotherapy alone,' says Mohamed ElBaradei. 'Our Programme of Action for Cancer Therapy (PACT), which draws on the Agency's long experience in radiation therapy, is building international partnerships to assist in cancer prevention, early detection, treatment and palliative care. Now, through the PACT Fund at NFCR, Americans have the opportunity to support these efforts and bring hope to millions of cancer patients in developing nations.' According to the World Health Organization (WHO), the world is on the brink of a cancer crisis. New cases are expected to double to more than 16 million a year by 2020, unless action is taken now. Hardest hit will be low-income countries, whose health systems are already overburdened by infectious diseases such as HIV/AIDS, Tuberculosis and Malaria. PACT, which was created within the IAEA in 2004, is forging international partnerships with other cancer organizations in both the public and private sectors. Together with partners such as WHO, the American Cancer Society (ACS), the National Cancer Institute (NCI) and the International Agency for Research on Cancer (IARC), it has established pilot projects called Model Demonstration Sites (PMDS) in six countries (Albania, Nicaragua, Sri Lanka, Tanzania, Vietnam and Yemen) to develop and implement comprehensive, integrated

  19. Force As A Momentum Current

    Munera, Hector A.

    2010-01-01

    Advantages of a neo-Cartesian approach to classical mechanics are noted. If conservation of linear momentum is the fundamental principle, Newton's three laws become theorems. A minor paradox in static Newtonian mechanics is identified, and solved by reinterpreting force as a current of momentum. Contact force plays the role of a mere midwife in the exchange of momentum; however, force cannot be eliminated from physics because it provides the numerical value for momentum current. In this sense, in a neo-Cartesian formulation of mechanics the concept of force becomes strengthened rather than weakened.

    A curvature self-interaction of the cosmic gas is shown to mimic a cosmological constant or other forms of dark energy, such as a rolling tachyon condensate or a Chaplygin gas. Any given Hubble rate and deceleration parameter can be traced back to the action of an effective curvature force on the gas particles. This force self-consistently reacts back on the cosmological dynamics. The links between an imperfect fluid description, a kinetic description with effective antifriction forces and curvature forces, which represent a non-minimal coupling of gravity to matter, are established

    Titin is a giant protein that provides elasticity to muscle. As the sarcomere is stretched, titin extends hierarchically according to the mechanics of its segments. Whether titin's globular domains unfold during this process and how such unfolded domains might contribute to muscle contractility are strongly debated. To explore the force-dependent folding mechanisms, here we manipulated skeletal-muscle titin molecules with high-resolution optical tweezers. In force-clamp mode, after quenching the force (force trace contained rapid fluctuations and a gradual increase of average force, indicating that titin can develop force via dynamic transitions between its structural states en route to the native conformation. In 4 M urea, which destabilizes H-bonds hence the consolidated native domain structure, the net force increase disappeared but the fluctuations persisted. Thus, whereas net force generation is caused by the ensemble folding of the elastically-coupled domains, force fluctuations arise due to a dynamic equilibrium between unfolded and molten-globule states. Monte-Carlo simulations incorporating a compact molten-globule intermediate in the folding landscape recovered all features of our nanomechanics results. The ensemble molten-globule dynamics delivers significant added contractility that may assist sarcomere mechanics, and it may reduce the dissipative energy loss associated with titin unfolding/refolding during muscle contraction/relaxation cycles. © 2017 The Protein Society.

    Forces are exerted on a centrifugal pump impeller, due to the asymmetry of the flow caused by the volute of diffuser, and to the motion of the center of the impeller whenever the shaft whirls. Recent work in the measurement of these forces as a function of the whirl speed to shaft speed ratio, and the influence of the volute, is reviewed. These forces may be decomposed into a steady force, a static stiffness matrix, a damping matrix and an inertia matrix. It is shown that for centrifugal p...

    Purpose: In mammography, the height of the image receptor is adjusted to the patient before compressing the breast. An inadequate height setting can result in an imbalance between the forces applied by the image receptor and the paddle, causing the clamped breast to be pushed up or down relative to the body during compression. This leads to unnecessary stretching of the skin and other tissues around the breast, which can make the imaging procedure more painful for the patient. The goal of this study was to implement a method to measure and minimize the force imbalance, and to assess its feasibility as an objective and reproducible method of setting the image receptor height. Methods: A trial was conducted consisting of 13 craniocaudal mammographic compressions on a silicone breast phantom, each with the image receptor positioned at a different height. The image receptor height was varied over a range of 12 cm. In each compression, the force exerted by the compression paddle was increased up to 140 N in steps of 10 N. In addition to the paddle force, the authors measured the force exerted by the image receptor and the reaction force exerted on the patient body by the ground. The trial was repeated 8 times, with the phantom remounted at a slightly different orientation and position between the trials. Results: For a given paddle force, the obtained results showed that there is always exactly one image receptor height that leads to a balance of the forces on the breast. For the breast phantom, deviating from this specific height increased the force imbalance by 9.4 ± 1.9 N/cm (6.7%) for 140 N paddle force, and by 7.1 ± 1.6 N/cm (17.8%) for 40 N paddle force. The results also show that in situations where the force exerted by the image receptor is not measured, the craniocaudal force imbalance can still be determined by positioning the patient on a weighing scale and observing the changes in displayed weight during the procedure. Conclusions: In mammographic breast

  16. Force transmissibility versus displacement transmissibility

    Science.gov (United States)

    Lage, Y. E.; Neves, M. M.; Maia, N. M. M.; Tcherniak, D.

    2014-10-01

    It is well-known that when a single-degree-of-freedom (sdof) system is excited by a continuous motion of the foundation, the force transmissibility, relating the force transmitted to the foundation to the applied force, equals the displacement transmissibility. Recent developments in the generalization of the transmissibility to multiple-degree-of-freedom (mdof) systems have shown that similar simple and direct relations between both types of transmissibility do not appear naturally from the definitions, as happens in the sdof case. In this paper, the authors present their studies on the conditions under which it is possible to establish a relation between force transmissibility and displacement transmissibility for mdof systems. As far as the authors are aware, such a relation is not currently found in the literature, which is justified by being based on recent developments in the transmissibility concept for mdof systems. Indeed, it does not appear naturally, but the authors observed that the needed link is present when the displacement transmissibility is obtained between the same coordinates where the applied and reaction forces are considered in the force transmissibility case; this implies that the boundary conditions are not exactly the same and instead follow some rules. This work presents a formal derivation of the explicit relation between the force and displacement transmissibilities for mdof systems, and discusses its potential and limitations. The authors show that it is possible to obtain the displacement transmissibility from measured forces, and the force transmissibility from measured displacements, opening new perspectives, for example, in the identification of applied or transmitted forces. With this novel relation, it becomes possible, for example, to estimate the force transmissibility matrix with the structure off its supports, in free boundary conditions, and without measuring the forces. As far as force identification is concerned, this

    Although long considered to be of marginal importance to global climate change, tropospheric aerosol contributes substantially to radiative forcing, and anthropogenic sulfate aerosol in particular has imposed a major perturbation to this forcing. Both the direct scattering of short wavelength solar radiation and the modification of the shortwave reflective properties of clouds by sulfate aerosol particles increase planetary albedo, thereby exerting a cooling influence on the planet. Current climate forcing due to anthropogenic sulfate is estimated to be -1 to -2 watts per square metre, globally averaged. This perturbation is comparable in magnitude to current anthropogenic greenhouse gas forcing but opposite in sign. Thus, the aerosol forcing has likely offset global greenhouse warming to a substantial degree. However, differences in geographical and seasonal distributions of these forcings preclude any simple compensation. Aerosol effects must be taken into account in evaluating anthropogenic influences on past, current, and projected future climate and in formulating policy regarding controls on emission of greenhouse gases and sulfur dioxide. Resolution of such policy issues requires integrated research on the magnitude and geographical distribution of aerosol climate forcing and on the controlling chemical and physical processes. 73 refs., 4 figs., 2 tabs.

  18. Microtubules as mechanical force sensors.

    Science.gov (United States)

    Karafyllidis, Ioannis G; Lagoudas, Dimitris C

    2007-03-01

    Microtubules are polymers of tubulin subunits (dimers) arranged on a hexagonal lattice. Each tubulin dimer comprises two monomers, the alpha-tubulin and beta-tubulin, and can be found in two states. In the first state a mobile negative charge is located into the alpha-tubulin monomer and in the second into the beta-tubulin monomer. Each tubulin dimer is modeled as an electrical dipole coupled to its neighbors by electrostatic forces. The location of the mobile charge in each dimer depends on the location of the charges in the dimer's neighborhood. Mechanical forces that act on the microtubule affect the distances between the dimers and alter the electrostatic potential. Changes in this potential affect the mobile negative charge location in each dimer and the charge distribution in the microtubule. The net effect is that mechanical forces affect the charge distribution in microtubules. We propose to exploit this effect and use microtubules as mechanical force sensors. We model each dimer as a two-state quantum system and, following the quantum computation paradigm, we use discrete quantum random walk on the hexagonal microtubule lattice to determine the charge distribution. Different forces applied on the microtubule are modeled as different coin biases leading to different probability distributions of the quantum walker location, which are directly connected to different charge distributions. Simulation results show that there is a strong indication that microtubules can be used as mechanical force sensors and that they can also detect the force directions and magnitudes.

    Fast, accurate, and robust nanomechanical measurements are intensely studied in materials science, applied physics, and molecular biology. Amplitude modulation force microscopy (tapping mode) is the most established nanoscale characterization technique of surfaces for air and liquid environments. However, its quantitative capabilities lag behind its high spatial resolution and robustness. We develop a general method to transform the observables into quantitative force measurements. The force reconstruction algorithm has been deduced on the assumption that the observables (amplitude and phase shift) are slowly varying functions of the tip–surface separation. The accuracy and applicability of the method is validated by numerical simulations and experiments. The method is valid for liquid and air environments, small and large free amplitudes, compliant and rigid materials, and conservative and non-conservative forces. (paper)

    Recent successes in ab initio calculations of light nuclei (A=2-6) will be reviewed and correlated with the dynamical consequences of chiral symmetry. The tractability of nuclear physics evinced by these results is evidence for that symmetry. The relative importance of three-nucleon forces, four-nucleon forces, multi-pion exchanges, and relativistic corrections will be discussed in the context of effective field theories and dimensional power counting. Isospin violation in the nuclear force will also be discussed in this context

    Molecular force spectroscopy has become a powerful tool to study how mechanics regulates biology, especially the mechanical regulation of molecular interactions and its impact on cellular functions. This force-driven methodology has uncovered a wealth of new information of the physical chemistry of molecular bonds for various biological systems. The new concepts, qualitative and quantitative measures describing bond behavior under force, and structural bases underlying these phenomena have substantially advanced our fundamental understanding of the inner workings of biological systems from the nanoscale (molecule) to the microscale (cell), elucidated basic molecular mechanisms of a wide range of important biological processes, and provided opportunities for engineering applications. Here, we review major force spectroscopic assays, conceptual developments of mechanically regulated kinetics of molecular interactions, and their biological relevance. We also present current challenges and highlight future directions.

    Abramowicz, M.A.; Max-Planck-Institut fuer Physik und Astrophysik, Garching

    1990-01-01

    The need for a rather fundamental revision in understanding of the nature of the centrifugal force is discussed. It is shown that in general relativity (and contrary to the situation in Newtonian theory) rotation of a reference frame is a necessary but not sufficient condition for the centrifugal force to appear. A sufficient condition for its appearance, in the instantaneously corotating reference frame of a particle, is that the particle motion in space (observed in the global rest frame) differs from a photon trajectory. The direction of the force is the same as that of the gradient of the effective potential for photon motion. In some cases, the centrifugal force will attract towards the axis of rotation. (author)

    Hellmann-Feynman theorems for partially extended arrangements of atoms (chains, strips, layers, wires and slabs) are derived and applied to one-, two-, and three-dimensional solids. The derivatives of the bulk energy with respect to the lattice spacings are related to the Hellmann-Feynman forces in the corresponding semi-infinite unrelaxed solids. These forces have to alternate going from the surface into the bulk provided that the latter is in equilibrium. (author)

  17. Is Gravity an Entropic Force?

    Directory of Open Access Journals (Sweden)

    Shan Gao

    2011-04-01

    Full Text Available The remarkable connections between gravity and thermodynamics seem to imply that gravity is not fundamental but emergent, and in particular, as Verlinde suggested, gravity is probably an entropic force. In this paper, we will argue that the idea of gravity as an entropic force is debatable. It is shown that there is no convincing analogy between gravity and entropic force in Verlinde’s example. Neither holographic screen nor test particle satisfies all requirements for the existence of entropic force in a thermodynamics system. Furthermore, we show that the entropy increase of the screen is not caused by its statistical tendency to increase entropy as required by the existence of entropic force, but in fact caused by gravity. Therefore, Verlinde’s argument for the entropic origin of gravity is problematic. In addition, we argue that the existence of a minimum size of spacetime, together with the Heisenberg uncertainty principle in quantum theory, may imply the fundamental existence of gravity as a geometric property of spacetime. This may provide a further support for the conclusion that gravity is not an entropic force.

  18. Logic circuits from zero forcing.

    Science.gov (United States)

    Burgarth, Daniel; Giovannetti, Vittorio; Hogben, Leslie; Severini, Simone; Young, Michael

    We design logic circuits based on the notion of zero forcing on graphs; each gate of the circuits is a gadget in which zero forcing is performed. We show that such circuits can evaluate every monotone Boolean function. By using two vertices to encode each logical bit, we obtain universal computation. We also highlight a phenomenon of "back forcing" as a property of each function. Such a phenomenon occurs in a circuit when the input of gates which have been already used at a given time step is further modified by a computation actually performed at a later stage. Finally, we show that zero forcing can be also used to implement reversible computation. The model introduced here provides a potentially new tool in the analysis of Boolean functions, with particular attention to monotonicity. Moreover, in the light of applications of zero forcing in quantum mechanics, the link with Boolean functions may suggest a new directions in quantum control theory and in the study of engineered quantum spin systems. It is an open technical problem to verify whether there is a link between zero forcing and computation with contact circuits.

    A calibration system and method utilizes acceleration of a mass to generate a force on the mass. An expected value of the force is calculated based on the magnitude and acceleration of the mass. A fixture is utilized to mount the mass to a force balance, and the force balance is calibrated to provide a reading consistent with the expected force determined for a given acceleration. The acceleration can be varied to provide different expected forces, and the force balance can be calibrated for different applied forces. The acceleration may result from linear acceleration of the mass or rotational movement of the mass.

  4. Climate hypersensitivity to solar forcing?

    Directory of Open Access Journals (Sweden)

    W. Soon

    2000-05-01

    Full Text Available We compare the equilibrium climate responses of a quasi-dynamical energy balance model to radiative forcing by equivalent changes in CO2, solar total irradiance (Stot and solar UV (SUV. The response is largest in the SUV case, in which the imposed UV radiative forcing is preferentially absorbed in the layer above 250 mb, in contrast to the weak response from global-columnar radiative loading by increases in CO2 or Stot. The hypersensitive response of the climate system to solar UV forcing is caused by strongly coupled feedback involving vertical static stability, tropical thick cirrus ice clouds and stratospheric ozone. This mechanism offers a plausible explanation of the apparent hypersensitivity of climate to solar forcing, as suggested by analyses of recent climatic records. The model hypersensitivity strongly depends on climate parameters, especially cloud radiative properties, but is effective for arguably realistic values of these parameters. The proposed solar forcing mechanism should be further confirmed using other models (e.g., general circulation models that may better capture radiative and dynamical couplings of the troposphere and stratosphere.Key words: Meteorology and atmospheric dynamics (climatology · general or miscellaneous · Solar physics · astrophysics · and astronomy (ultraviolet emissions

  5. Casimir Force Between Quantum Plasmas

    Buenzli, P.

    2005-01-01

    Field fluctuations are responsible for an attractive force - the Casimir force - between two parallel (globally neutral) metallic plates separated by a distance d. At high temperature, or equivalently large d, this force is known to exhibit a classical and universal character (independent of the material constitution of the plates). In a recent work, we have displayed the microscopic mechanisms responsible for this universality within a classical model. The plates consist of slabs containing classical charged particles in fluid phase and thermal equilibrium (plasmas). The universality of the force proves to originate from screening sum rules satisfied by the charge correlations. Here we show how this result is altered when the quantum-mechanical nature of the particles is taken into account. It turns out that in addition to the classical result, the asymptotic force for large d comprises a non-universal quantum correction, which is, however, small at high temperature. The method relies on an exact representation of the charge correlations by quantum Mayer graphs, based on the Feynman-Kac path integral formalism. (author)

  9. Transversal light forces in semiconductors

    CERN Document Server

    Lindberg, M

    2003-01-01

    The transversal light force is a well established effect in atomic and molecular systems that are exposed to spatially inhomogeneous light fields. In this paper it is shown theoretically that in an excited semiconductor, containing an electron-hole plasma or excitons, a similar light force exists, if the semiconductor is exposed to an ultrashort spatially inhomogeneous light field. The analysis is based on the equations of motion for the Wigner distribution functions of charge carrier populations and interband polarizations. The results show that, while the light force on the electron-hole plasma or the excitons does exist, its effects on the kinetic behaviour of the electron-hole plasma or the excitons are different compared to the situation in an atomic or molecular system. A detailed analysis presented here traces this difference back to the principal differences between atoms and molecules on the one hand and electron-hole plasmas or excitons on the other hand.

    The disposal of the heat released from a 1000MW power plant needs a natural draft tower of about 130m of diameter at the base, and 170m height, or a cooling system with a draft forced by about forty vans, a hundred meters in diameter, and thirty meters height. The plumes from atmospheric cooling systems form, in terms of fluid mechanics, hot jets in a cross current. They consist in complex flows that must be finely investigated with experimental and computer means. The study, currently being performed at the National Hydraulics Laboratory, shows that as far as the length and height of visible plumes are concerned, the comparison is favorable to some types of forced draft cooling system, for low and medium velocities, (below 5 or 6m/s at 10m height. Beyond these velocities, the forced draft sends the plume up to smaller heights, but the plume is generally more dilute [fr

    Full Text Available Building an effective sales force starts with selecting good salespeople, but good salespeople are very difficult to find. The reason for this is that most sales jobs are very demanding and require a great deal from the salesperson. There are many different types of sales jobs. Before it can hire salespeople, each company must do a careful job analysis to see what particular types of selling and other skills are necessary for each sales job. One task of the market planner is to establish clear objectives each year for the entire sales force, for each region, each sales office, and each salesperson. Sales jobs are different from in-house jobs in some significant ways. Nevertheless, each company must continually work on building and maintaining an effective sales force using the following steps: recruitment, selection, training, compensation and evaluation of each salesperson.

    Full Text Available Clarinettists close and open multiple tone holes to alter the pitch of the tones. Their fingering technique must be fast, precise, and coordinated with the tongue articulation. In this empirical study, finger force profiles and tongue techniques of clarinet students (N = 17 and professional clarinettists (N = 6 were investigated under controlled performance conditions. First, in an expressive-performance task, eight selected excerpts from the first Weber Concerto were performed. These excerpts were chosen to fit in a 2 x 2 x 2 design (register: low--high; tempo: slow--fast, dynamics: soft--loud. There was an additional condition controlled by the experimenter, which determined the expression levels (low--high of the performers. Second, a technical-exercise task, an isochronous 23-tone melody was designed that required different effectors to produce the sequence (finger-only, tongue-only, combined tongue-finger actions. The melody was performed in three tempo conditions (slow, medium, fast in a synchronization-continuation paradigm. Participants played on a sensor-equipped Viennese clarinet, which tracked finger forces and reed oscillations simultaneously. From the data, average finger force (Fmean and peak force (Fmax were calculated. The overall finger forces were low (Fmean = 1.17 N, Fmax = 3.05 N compared to those on other musical instruments (e.g. guitar. Participants applied the largest finger forces during the high expression level performance conditions (Fmean = 1.21 N.For the technical exercise task, timing and articulation information were extracted from the reed signal. Here, the timing precision of the fingers deteriorated the timing precision of the tongue for combined tongue-finger actions, especially for faster tempi. Although individual finger force profiles were overlapping, the group of professional players applied less finger force overall (Fmean = 0.54 N. Such sensor instruments provide useful insights into player

  20. Force-Time Entropy of Isometric Impulse.

    2016-01-01

    The relation between force and temporal variability in discrete impulse production has been viewed as independent (R. A. Schmidt, H. Zelaznik, B. Hawkins, J. S. Frank, & J. T. Quinn, 1979 ) or dependent on the rate of force (L. G. Carlton & K. M. Newell, 1993 ). Two experiments in an isometric single finger force task investigated the joint force-time entropy with (a) fixed time to peak force and different percentages of force level and (b) fixed percentage of force level and different times to peak force. The results showed that the peak force variability increased either with the increment of force level or through a shorter time to peak force that also reduced timing error variability. The peak force entropy and entropy of time to peak force increased on the respective dimension as the parameter conditions approached either maximum force or a minimum rate of force production. The findings show that force error and timing error are dependent but complementary when considered in the same framework with the joint force-time entropy at a minimum in the middle parameter range of discrete impulse.

    We extend previous studies [1] of vertical displacement events (VDE) which can produce disruptions. The emphasis is on the non axisymmetric ``sideways'' wall force Fx. Simulations are performed using the M3D [2] code. A VDE expels magnetic flux through the resistive wall until the last closed flux surface has q VDE is presented. The wall force depends strongly on γτw, where γ is the mode growth rate and τw is the wall resistive penetration time. The force Fx is largest when γτw is a constant of order unity, which depends on the initial conditions. For large values of γτw, the wall force asymptotes to a relatively smaller value, well below the critical value ITER is designed to withstand. The principle of disruption mitigation by massive gas injection is to cause a disruption with large γτw. [4pt] [1] H. R. Strauss, R. Paccagnella, and J. Breslau,Phys. Plasmas 17, 082505 (2010) [2] W.

  8. Ponderomotive force near cyclotron resonance

    1987-01-01

    The ponderomotive force, which is involved in the excitation of macroscopic behaviors of plasma caused by wave motion, plays an important role in various non-linear wave motion phenomena. In the present study, equations for the pondermotive force for plasma in a uniform magnetic field is derived using a renormalization theory which is based on the Vlasov equation. It is shown that the pondermotive force, which diverges at the cyclotron resonence point according to adiabatic approximation, can be expressed by a non-divergent equation by taking into account the instability of the cyclotron orbit due to high-order scattering caused by a wave. This is related with chaotic particle behaviors near cyclotron resonance, where the pondermotive force is small and the diffusion process prevails. It is assumed here that the amplitude of the high-frequency electric field is not large and that the broadening of cyclotron levels is smaller than the distance between the levels. A global chaos will be created if the amplitude of the electric field becomes greater to allow the broadening to exceed the distance between the levels. (Nogami, K.).

    Two years ago NASA established the Ad Hoc Big Data Task Force (BDTF - https://science.nasa.gov/science-committee/subcommittees/big-data-task-force), an advisory working group with the NASA Advisory Council system. The scope of the Task Force included all NASA Big Data programs, projects, missions, and activities. The Task Force focused on such topics as exploring the existing and planned evolution of NASA's science data cyber-infrastructure that supports broad access to data repositories for NASA Science Mission Directorate missions; best practices within NASA, other Federal agencies, private industry and research institutions; and Federal initiatives related to big data and data access. The BDTF has completed its two-year term and produced several recommendations plus four white papers for NASA's Science Mission Directorate. This presentation will discuss the activities and results of the TF including summaries of key points from its focused study topics. The paper serves as an introduction to the papers following in this ESSI session.

  11. Nuclear force from string theory

    International Nuclear Information System (INIS)

    Hashimoto, Koji; Sakai, Tadakatsu; Sugimoto, Shigeki

    2009-01-01

    We compute the nuclear force in a holographic model of QCD on the basis of a D4-D8 brane configuration in type IIA string theory. The repulsive core of nucleons is important in nuclear physics, but its origin has not been well understood in strongly coupled QCD. We find that the string theory via gauge/string duality deduces this repulsive core at a short distance between nucleons. Since baryons in the model are realized as solitons given by Yang-Mills instanton configuration on flavor D8-branes, ADHM construction of two instantons probes well the nucleon interaction at short scale, which provides the nuclear force quantitatively. We obtain a central force, as well as a tensor force, which is strongly repulsive as suggested in experiments and lattice results. In particular, the nucleon-nucleon potential V(r) (as a function of the distance) scales as r -2 , which is peculiar to the holographic model. We compare our results with the one-boson exchange model using the nucleon-nucleon-meson coupling obtained in our previous paper. (author)

    2012-02-10

    We report Lorentz force-induced actuation of a silicon microcantilever having an integrated resistive heater. Oscillating current through the cantilever interacts with the magnetic field around a NdFeB permanent magnet and induces a Lorentz force that deflects the cantilever. The same current induces cantilever heating. With AC currents as low as 0.2 mA, the cantilever can be oscillated as much as 80 nm at resonance with a DC temperature rise of less than 5 °C. By comparison, the AC temperature variation leads to a thermomechanical oscillation that is about 1000 times smaller than the Lorentz deflection at the cantilever resonance. The cantilever position in the nonuniform magnetic field affects the Lorentz force-induced deflection, with the magnetic field parallel to the cantilever having the largest effect on cantilever actuation. We demonstrate how the cantilever actuation can be used for imaging, and for measuring the local material softening temperature by sensing the contact resonance shift.

  3. Electronic transitions and intermolecular forces

    International Nuclear Information System (INIS)

    Hemert, M.C. van.

    1981-01-01

    This thesis describes two different subjects - electronic transitions and intermolecular forces - that are related mainly by the following observation: The wavenumber at which an electronic transition in an atom or molecule occurs, depends on the environment of that atom or molecule. This implies, for instance, that when a molecule becomes solvated its absorption spectrum may be shifted either to the blue or to the red side of the original gasphase spectrum. In part I attention is paid to the experimental aspects of VUV spectroscopy, both in the gasphase and in the condensed phase. In part II a series of papers are presented, dealing with the calculation of intermolecular forces (and some related topics) both for the ground state and for the excited state interactions, using different non-empirical methods. The calculations provide, among other results, a semiquantitative interpretation of the spectral blue shifts encountered in our experiments. (Auth.)

  4. Chiral forces and molecular dissymmetry

    International Nuclear Information System (INIS)

    Mohan, R.

    1992-01-01

    Chiral molecules leading to helical macromolecules seem to preserve information and extend it better. In the biological world RNA is the very paradigm for self-replication, elongation and autocatalytic editing. The nucleic acid itself is not chiral. It acquires its chirality by association with D-sugars. Although the chiral information or selectivity put in by the unit monomer is no longer of much interest to the biologists - they tend to leave it to the Darwinian selection principle to take care of it as illustrated by Frank's model - it is vital to understand the origin of chirality. There are three different approaches for the chiral origin of life: (1) Phenomenological, (2) Electromagnetic molecular and Coriolis forces and (3) Atomic or nuclear force, the neutral weak current. The phenomenological approach involves spontaneous symmetry breaking fluctuations in far for equilibrium systems or nucleation and crystallization. Chance plays a major role in the chiral molecule selected

  6. Physicists' Forced Migrations under Hitler

    Science.gov (United States)

    Beyerchen, Alan

    2011-03-01

    When the Nazis came to power in early 1933 they initiated formal and informal measures that forced Jews and political opponents from public institutions such as universities. Some physicists retired and others went into industry, but most emigrated. International communication and contact made emigration a viable option despite the desperate economic times in the Great Depression. Another wave of emigrations followed the annexation of Austria in 1938. Individual cases as well as general patterns of migration and adaptation to new environments will be examined in this presentation. One important result of the forced migrations was that many of the physicists expelled under Hitler played important roles in strengthening physics elsewhere, often on the Allied side in World War II.

  7. The nature of motive force

    CERN Document Server

    Pramanick, Achintya Kumar

    2014-01-01

    In this monograph Prof. Pramanick explicates the law of motive force, a fundamental law of nature that can be observed and appreciated as an addition to the existing laws of thermodynamics. This unmistakable and remarkable tendency of nature is equally applicable to all other branches of studies. He first conceptualized the law of motive force in 1989, when he was an undergraduate student. Here he reports various applications of the law in the area of  thermodynamics, heat transfer, fluid mechanics and solid mechanics, and shows how it is possible to solve analytically century-old unsolved problems through its application. This book offers a comprehensive account of the law and its relation to other laws and principles, such as the generalized conservation principle, variational formulation, Fermat’s principle, Bejan’s constructal law, entropy generation minimization, Bejan’s method of intersecting asymptotes and equipartition principle. Furthermore, the author addresses some interrelated fundamental p...

    The optical Sagnac effect is considered, when the fictitious gravitational field simulates the reflections from the mirrors. It is shown that no contradiction exists between the conclusions of the laboratory and rotated observers. Because of the acting of gravity-like Coriolis force the trajectories of co- and anti-rotating photons have different radii in the rotating reference frame, while in the case of the equal radius the effective gravitational potentials for the photons have to be different.

    The stability of graphene cantilever under Casimir attraction to an underlying conductor is investigated. The dependence of the instability threshold on temperature and flexural rigidity is obtained. Analytical work is supplemented by numerical computation of the critical temperature above which the graphene cantilever irreversibly bends down and attaches to the conductor. The geometry of the attachment and exfoliation of the graphene sheet is discussed. It is argued that graphene cantilever can be an excellent tool for precision measurements of the Casimir force.

    2009-01-01

    Biomechanical forces are emerging as critical regulators of embryogenesis, particularly in the developing cardiovascular system1,2. After initiation of the heartbeat in vertebrates, cells lining the ventral aspect of the dorsal aorta, the placental vessels, and the umbilical and vitelline arteries initiate expression of the transcription factor Runx1 (refs 3–5), a master regulator of haematopoiesis, and give rise to haematopoietic cells4. It remains unknown whether the biomechanical forces imposed on the vascular wall at this developmental stage act as a determinant of haematopoietic potential6. Here, using mouse embryonic stem cells differentiated in vitro, we show that fluid shear stress increases the expression of Runx1 in CD41+c-Kit+ haematopoietic progenitor cells7,concomitantly augmenting their haematopoietic colony-forming potential. Moreover, we find that shear stress increases haematopoietic colony-forming potential and expression of haematopoietic markers in the paraaortic splanchnopleura/aorta–gonads–mesonephros of mouse embryos and that abrogation of nitric oxide, a mediator of shear-stress-induced signalling8, compromises haematopoietic potential in vitro and in vivo. Collectively, these data reveal a critical role for biomechanical forces in haematopoietic development. PMID:19440194

  13. Exotic Nuclei and Yukawa's Forces

    International Nuclear Information System (INIS)

    2008-01-01

    In this plenary talk, we will overview the evolution of the shell structure in stable and exotic nuclei as a new paradigm of nuclear structure physics. This shell evolution is primarily due to the tensor force. The robust mechanism and some examples will be presented. Such examples include the disappearance of existing magic numbers and the appearance of new ones. The nuclear magic numbers have been believed, since Mayer and Jensen, to be constants as 2, 8, 20, 28, 50, ... This turned out to be changed, once we entered the regime of exotic nuclei. This shell evolution develops at many places on the nuclear chart in various forms. For example, superheavy magic numbers may be altered. Thus, we are led to a new paradigm as to how and where the nuclear shell evolves, and what consequences arise. The evolution of the shell affects weak process transitions, and plays a crucial role in deformation. The π and ρ mesons generate tensor forces, and are the fundamental elements of such intriguing phenomena. Thus, physics of exotic nuclei arises as a manifestation of Yukawa's forces

  14. Origin of Knudsen forces on heated microbeams

    KAUST Repository

    2010-09-09

    The presented work probes the fundamentals of Knudsen forces. Using the direct simulation Monte Carlo (DSMC) method, the flows induced by temperature inhomogeneity within a representative configuration and the Knudsen force acting on a heated microbeam are captured as functions of Knudsen number in the entire flow regime. Both flow strength and Knudsen force peak in the transition regime and negative Knudsen force absent in experimental data is observed. The mechanisms of the thermally induced flows and Knudsen forces are studied. It has been found that thermal edge flow is the main driven source for the formation of the Knudsen force on microbeams and domain configuration plays an important role in the process.

    The asymmetric flow around an impeller in a volute exerts a force upon the impeller. To study the rotordynamic force on an impeller which is vibrating around its machine axis of rotation, the impeller, mounted on a dynamometer, is made to whirl in a circular orbit within the volute. The measured force is expressed as the sum of a steady radial force and an unsteady force due to the eccentric motion of the impeller. These forces were measured in separate tests on a centrifugal pump with rad...

    Directory of Open Access Journals (Sweden)

    Liam Collins

    2015-01-01

    Full Text Available Conventional closed loop-Kelvin probe force microscopy (KPFM has emerged as a powerful technique for probing electric and transport phenomena at the solid–gas interface. The extension of KPFM capabilities to probe electrostatic and electrochemical phenomena at the solid–liquid interface is of interest for a broad range of applications from energy storage to biological systems. However, the operation of KPFM implicitly relies on the presence of a linear lossless dielectric in the probe–sample gap, a condition which is violated for ionically-active liquids (e.g., when diffuse charge dynamics are present. Here, electrostatic and electrochemical measurements are demonstrated in ionically-active (polar isopropanol, milli-Q water and aqueous NaCl and ionically-inactive (non-polar decane liquids by electrochemical force microscopy (EcFM, a multidimensional (i.e., bias- and time-resolved spectroscopy method. In the absence of mobile charges (ambient and non-polar liquids, KPFM and EcFM are both feasible, yielding comparable contact potential difference (CPD values. In ionically-active liquids, KPFM is not possible and EcFM can be used to measure the dynamic CPD and a rich spectrum of information pertaining to charge screening, ion diffusion, and electrochemical processes (e.g., Faradaic reactions. EcFM measurements conducted in isopropanol and milli-Q water over Au and highly ordered pyrolytic graphite electrodes demonstrate both sample- and solvent-dependent features. Finally, the feasibility of using EcFM as a local force-based mapping technique of material-dependent electrostatic and electrochemical response is investigated. The resultant high dimensional dataset is visualized using a purely statistical approach that does not require a priori physical models, allowing for qualitative mapping of electrostatic and electrochemical material properties at the solid–liquid interface.

    This study was undertaken to inform disability mitigation for military veterans by identifying personal, environmental, and health factors associated with activity limitations. A sample of 3154 Canadian Armed Forces Regular Force Veterans who were released during 1998-2007 participated in the 2010 Survey on Transition to Civilian Life. Associations between personal and environmental factors, health conditions and activity limitations were explored using ordinal logistic regression. The prevalence of activity reduction in life domains was higher than the Canadian general population (49% versus 21%), as was needing assistance with at least one activity of daily living (17% versus 5%). Prior to adjusting for health conditions, disability odds were elevated for increased age, females, non-degree post-secondary graduation, low income, junior non-commissioned members, deployment, low social support, low mastery, high life stress, and weak sense of community belonging. Reduced odds were found for private/recruit ranks. Disability odds were highest for chronic pain (10.9), any mental health condition (2.7), and musculoskeletal conditions (2.6), and there was a synergistic additive effect of physical and mental health co-occurrence. Disability, measured as activity limitation, was associated with a range of personal and environmental factors and health conditions, indicating multifactorial and multidisciplinary approaches to disability mitigation.

    2011-02-01

    Atomic force microscopy (AFM) and AFM-based force spectroscopy was used to study the desorption of individual chitosan polymer chains from substrates with varying chemical composition. AFM images of chitosan adsorbed onto a flat mica substrate show elongated single strands or aggregated bundles. The aggregated state of the polymer is consistent with the high level of flexibility and mobility expected for a highly positively charged polymer strand. Conversely, the visualization of elongated strands indicated the presence of stabilizing interactions with the substrate. Surfaces with varying chemical composition (glass, self-assembled monolayer of mercaptoundecanoic acid/decanethiol and polytetrafluoroethylene (PTFE)) were probed with chitosan modified AFM tips and the corresponding desorption energies, calculated from plateau-like features, were attributed to the desorption of individual polymer strands. Desorption energies of 2.0±0.3×10(-20)J, 1.8±0.3×10(-20)J and 3.5±0.3×10(-20)J were obtained for glass, SAM of mercaptoundecanoic/dodecanethiol and PTFE, respectively. These single molecule level results can be used as a basis for investigating chitosan and chitosan-based materials for biomaterial applications. Copyright © 2010 Elsevier B.V. All rights reserved.

    Measurements, using atomic force microscopy, of the force and force derivative on a charged insulating micron sized sphere as a function of gap between the sphere and a conductive plane have revealed attractive forces at finite gaps that are larger than predicted by either van der Waals or conventional electrostatic forces. We suggest that these observations may be due to an electrostatic force that we have identified theoretically and call the proximity force. This proximity force is due to the discrete charges on the surface of the sphere in close proximity to the plane

    The short distance forces between 3 valence quarks in the proton are investigated in perturbative QCD formulated on the light cone. These forces are the driving terms in the Brodsky-Lepage type evolution equation for the partially decomposed distribution amplitudes. The one-gluon exchange force, which is the lowest order force in the running coupling constant αsub(s) retains the SU(6) symmetry, while the αsub(s) 2 -order force, corresponding to one Coulomb gluon and one transverse gluon, breaks the SU(6) symmetry. The latter force contributes to the deviation from 1/2 of the d/u ratio for the proton, observed experimentally. In the kinematical domain of one fast quark, the αsub(s) 2 -order force gives the leading (1-x) 3 behaviour of the deep inelastic structure function F 2 (x), in contrast to the αsub(s)-order force, which gives (1-x) 5 , for xapprox.=1.

  14. The forced nonlinear Schroedinger equation

    The nonlinear Schroedinger equation describes the behaviour of a radio frequency wave in the ionosphere near the reflexion point where nonlinear processes are important. A simple model of this phenomenon leads to the forced nonlinear Schroedinger equation in terms of a nonlinear boundary value problem. A WKB analysis of the time evolution equations for the nonlinear Schroedinger equation in the inverse scattering transform formalism gives a crude order of magnitude estimation of the qualitative behaviour of the solutions. This estimation is compared with the numerical solutions. (D.Gy.)

  15. Factors Affecting Aerosol Radiative Forcing

    Rapid industrial and economic growth has meant large amount of aerosols in the atmosphere with strong radiative forcing (RF) upon the climate system. Over parts of the globe, the negative forcing of aerosols has overcompensated for the positive forcing of greenhouse gases. Aerosol RF is determined by emissions and various chemical-transport-radiative processes in the atmosphere, a multi-factor problem whose individual contributors have not been well quantified. In this study, we analyze the major factors affecting RF of secondary inorganic aerosols (SIOAs, including sulfate, nitrate and ammonium), primary organic aerosol (POA), and black carbon (BC). We analyze the RFof aerosols produced by 11 major regions across the globe, including but not limited to East Asia, Southeast Asia, South Asia, North America, and Western Europe. Factors analyzed include population size, per capita gross domestic production (GDP), emission intensity (i.e., emissionsper unit GDP), chemical efficiency (i.e., mass per unit emissions) and radiative efficiency (i.e., RF per unit mass). We find that among the 11 regions, East Asia produces the largest emissions and aerosol RF, due to relatively high emission intensity and a tremendous population size.South Asia produce the second largest RF of SIOA and BC and the highest RF of POA, in part due to its highest chemical efficiency among all regions. Although Southeast Asia also has large emissions,its aerosol RF is alleviated by its lowest chemical efficiency.The chemical efficiency and radiative efficiency of BC produced by the Middle East-North Africa are the highest across the regions, whereas its RF is loweredbyasmall per capita GDP.Both North America and Western Europe have low emission intensity, compensating for the effects on RF of large population sizes and per capita GDP. There has been a momentum to transfer industries to Southeast Asia and South Asia, and such transition is expected to continue in the coming years. The resulting

    A grasp force sensor for robotic hands is disclosed. A flexible block is located in the base of each claw through which the grasp force is exerted. The block yields minute parallelogram deflection when the claws are subjected to grasping forces. A parallelogram deflection closely resembles pure translational deflection, whereby the claws remain in substantial alignment with each other during grasping. Strain gauge transducers supply signals which provide precise knowledge of and control over grasp forces.

    The Ehrenfest force in an inhomogeneous magnetic field is calculated. It is shown that there exist such (very rare) topologically nontrivial physical situations when the Gauss theorem in its classic formulation fails and, as a consequence, apart from the usual Lorentz force an additional, purely imaginary force acts on the charged particle. This force arises only in inhomogeneous magnetic fields of special configurations, has a purely quantum origin, and disappears in the classical limit

    We have developed a force measurement system which enables us to directly measure the levitation force of levitated bulk superconductors. Experimental data of the levitation forces were compared with the results of numerical simulation based on the levitation model that we deduced in our previous paper. They were in fairly good agreement, which confirms that our levitation model can be applied to the force analyses for levitated bulk superconductors. (author)
