    Full Text Available The current study measured neural responses to investigate auditory stream segregation of noise stimuli with or without clear spectral contrast. Sequences of alternating A and B noise bursts were presented to elicit stream segregation in normal-hearing listeners. The successive B bursts in each sequence maintained an equal amount of temporal separation with manipulations introduced on the last stimulus. The last B burst was either delayed for 50% of the sequences or not delayed for the other 50%. The A bursts were jittered in between every two adjacent B bursts. To study the effects of spectral separation on streaming, the A and B bursts were further manipulated by using either bandpass-filtered noises widely spaced in center frequency or broadband noises. Event-related potentials (ERPs to the last B bursts were analyzed to compare the neural responses to the delay vs. no-delay trials in both passive and attentive listening conditions. In the passive listening condition, a trend for a possible late mismatch negativity (MMN or late discriminative negativity (LDN response was observed only when the A and B bursts were spectrally separate, suggesting that spectral separation in the A and B burst sequences could be conducive to stream segregation at the pre-attentive level. In the attentive condition, a P300 response was consistently elicited regardless of whether there was spectral separation between the A and B bursts, indicating the facilitative role of voluntary attention in stream segregation. The results suggest that reliable ERP measures can be used as indirect indicators for auditory stream segregation in conditions of weak spectral contrast. These findings have important implications for cochlear implant (CI studies – as spectral information available through a CI device or simulation is substantially degraded, it may require more attention to achieve stream segregation.

    A combination of the conventional and Matthaei lowpass-bandpass transformations is shown to result in some bandpass filters having very good arithmetic symmetry. The technique presented is applicable to the Butterworth and inverse Chebyshev types of magnitude approximations and the Bessel type of delay approximations. It is not valid, however, for the Chebyshev and elliptic varieties of filters.

    New and more effective treatments for cancer have resulted in individuals living longer with a better quality of life. Many more survivors are employed in the workplace. Cancer is no longer only an issue for survivors and their families; it has become an issue for the employer and the workplace. This article describes survey results of 4,364 long term cancer survivors in which they were asked to respond to items describing their ability to work, job discrimination, and quality of life. Thirty-five percent of survivors were working at the time they completed the survey, and 8.5% considered themselves unable to work. This research has shown that age, gender, ethnic group, and cancer type affected the working status of the survivors. Of survivors continuing to work, 7.3% indicated they had experienced job discrimination. The results indicate most cancer survivors do not perceive employment related problems, and are readily assimilated into the work force. Job discrimination and the ability to work is a quality of life issue.

  5. Gender relations and economic issues.

    Science.gov (United States)

    Elson, D

    1993-10-01

    While most discussions of economic issues pay no explicit attention to gender relations, most economic policy is marked by male bias which provides women with an unequal access to resources. This situation exists because most economists, officials, and business managers lack the imagination to see the gender impact of economic issues and most women's groups and researchers lack the language to portray this connection. This article explores some aspects of this gap and aims to provide women with the ability to effectively discuss economic issues. After an introduction, the article considers the basic problem caused by the fact that the economy is defined primarily in terms of money-making activities. This leads to a male bias since much of women's work occurs outside of the monetary sphere. The next section looks at how a failure to understand the significance of gender relations will interfere with the fulfillment of policy objectives. This discussion is followed by a description of how cutbacks in government expenditures increase the burden on women who must replace the services. Problems with the option of the private-sector replacing government services, such as the fact that increasing disposable income in households does not guarantee that unpaid labor will be reduced and the fact that the private sector may fail to expand in a productive way, are covered. The article then touches on the new emphasis placed by some economists and policy makers on cooperative and interactive solutions to these problems and ends by mentioning three new initiatives which seek to build capacity for gender-aware economic analysis: the development of a training program at Manchester University in the UK, coordination of an international research workshop by the University of Utah in the US, and development of an international association for feminist economics based in the US.

    1999-01-01

    Various initiatives have been undertaken by the Federal Energy Regulatory Commission (FERC) to deregulate wholesale electric energy markets. These initiatives have focused on restructuring the transmission systems in the US and recently have culminated in a proposal requiring formation of and participation in regional transmission organizations. The overall form of regulation selected to determine rates for transmission entities as well as underlying regulatory decisions reached on key issues will have profound implications for transmission entities. For example, traditional cost-based regulation would require one set of accounting and reporting rules, while incentive-based regulation may not be subject to those same rules. An overview of some of the major accounting and financial reporting issues that will need to be considered is presented

    2003-01-01

    Concerns about the erroneous diagnosis of death and premature burial have been expressed from times immemorial. Patients with brain stem death have absolutely no chance of recovery. Brain death is considered at par with death in most of the countries. General public in most parts of the world shows reluctance to accept this concept due to different social, cultural and religious backgrounds and state of literacy and awareness. The criteria for the diagnosis of brain death have been established which include certain pre-conditions, exclusions and tests of the brain stem function. These criteria are universally accepted. The criteria in children are somewhat different from the adults. The subject is intimately related with organ transplantation. If the patients is registered as organ donor or the family consents, organs can be harvested from brain dead patients for transplantation. Pakistan is amongst the few countries where no legislation exists to accept brain death as being at par with death of an individual, and to facilitate and regulate, cadaveric organ donation and transplantation.

    2014-01-01

    Two different designs combining a bandpass and a notch filter are developed to operate in the receiving band from 350–470 MHz. The bandpass filter is designed from a simple structure, by use of only four short circuited stubs and a half wavelength transmission line connecting the stubs. The tunable...... notch filter ensures an attenuation level of 19.3 dB to 27.3 dB in the frequency range from 360–480 MHz. The measured passband ripple of the combined filter is less than 0.5 dB, while the insertion loss for the simplest design is less than 1.7 dB only 10 MHz from the notch frequency. Even though...... the wavelength on the selected substrate (εr = 3.55) is approximately 45 cm, the outer dimensions of the final filter only measure 10×10 cm2....

    Bulzacchelli, J.F.; Lee, H.-S.; Misewich, J.A.; Ketchen, M.B.

    1999-01-01

    Bandpass delta-sigma modulators digitize narrowband signals with high dynamic range and linearity. The required sampling rate is only a few times higher than the centre frequency of the input. This paper presents a superconducting bandpass delta-sigma modulator for direct analogue-to-digital conversion of RF signals in the GHz range. The input signal is capacitively coupled to one end of a microstrip transmission line, and a single flux quantum balanced comparator quantizes the current flowing out of the other end. Quantization noise is suppressed at the quarter-wave resonance of the transmission line (about 2 GHz in our design). Circuit performance at a 20 GHz sampling rate has been studied with several long JSIM simulations. Full-scale (FS) input sensitivity is 20 mV (rms), and in-band noise is -53 dBFS and -57 dBFS over bandwidths of 39 MHz and 19.5 MHz, respectively. In-band intermodulation distortion is better than -69 dBFS. (author)

  1. Highly Tunable Narrow Bandpass MEMS Filter

    KAUST Repository

    Hafiz, Md Abdullah Al

    2017-07-07

    We demonstrate a proof-of-concept highly tunable narrow bandpass filter based on electrothermally and electrostatically actuated microelectromechanical-system (MEMS) resonators. The device consists of two mechanically uncoupled clamped-clamped arch resonators, designed such that their resonance frequencies are independently tuned to obtain the desired narrow passband. Through the electrothermal and electrostatic actuation, the stiffness of the structures is highly tunable. We experimentally demonstrate significant percentage tuning (~125%) of the filter center frequency by varying the applied electrothermal voltages to the resonating structures, while maintaining a narrow passband of 550 ± 50 Hz, a stopband rejection of >17 dB, and a passband ripple ≤ 2.5 dB. An analytical model based on the Euler-Bernoulli beam theory is used to confirm the behavior of the filter, and the origin of the high tunability using electrothermal actuation is discussed.

  2. Pertinent issues related to laparoscopic radical prostatectomy

    Directory of Open Access Journals (Sweden)

    Sidney C. Abreu

    2003-12-01

    Full Text Available PURPOSE: We describe the critical steps of the laparoscopic radical prostatectomy (LRP technique and discuss how they impact upon the pertinent issues regarding prostate cancer surgery: blood loss, potency and continence. RESULTS: A major advantage of LRP is the reduced operative blood loss. The precise placement of the dorsal vein complex stitch associated with the tamponading effect of the CO2 pneumoperitoneum significantly decrease venous bleeding, which is the main source of blood loss during radical prostatectomy. At the Cleveland Clinic, the average blood loss of our first 100 patients was 322.5 ml, resulting in low transfusion rates. The continuous venous bleeding narrowed pelvic surgical field and poor visibility can adversely impact on nerve preservation during open radical prostatectomy. Laparoscopy, with its enhanced and magnified vision in a relatively bloodless field allows for excellent identification and handling of the neurovascular bundles. During open retropubic radical prostatectomy, the pubic bone may impair visibility and access to the urethral stump, and the surgeon must tie the knots relying on tactile sensation alone. Consequently, open prostatectomy is associated with a prolonged catheterization period of 2 - 3 weeks. Comparatively, during laparoscopic radical prostatectomy all sutures are meticulously placed and each is tied under complete visual control, resulting in a precise mucosa-to-mucosa approximation. CONCLUSION: The laparoscopic approach may represent a reliable less invasive alternative to the conventional open approach. Despite the encouraging preliminary anatomical and functional outcomes, prospective randomized comparative trials are required to critically evaluate the role of laparoscopy for this sophisticated and delicate operation.

    Acute viral gastroenteritis is a major health issue worldwide and is associated with high annual mortality, particularly in children of developing countries. Rotaviruses, caliciviruses and astroviruses are the main causes. Accurate diagnoses are possible by recently developed molecular techniques. In many setups, zoonotic transmission is an important epidemiological factor. Treatment consists of rehydration and is otherwise symptomatic. The worldwide introduction of universal rotavirus vaccination of infants has significantly reduced rotavirus disease and mortality.

    When a dose reconstruction is performed around some nuclear site, a decision has to be made as to whether an epidemiologic study should be performed there and, if so, what form the study should take. The goal of this paper is to provide an overview of epidemiologic and biostatistical issues that help determine whether an epidemiologic study around a nuclear facility is worthwhile doing from a scientific standpoint. We are all aware that public health and sociopolitical concerns often assume considerable importance in these decisions, but they will not be considered here. 27 refs., 2 tabs

  8. Environmental issues related to biomass: An overview

    International Nuclear Information System (INIS)

    Hughes, M.; Ranney, J.W.

    1993-01-01

    With public attention increasingly focused on environmentalism and climate change, there is enormous potential for the commercial use of biomass to accelerate. Renewable feedstocks such as biomass can provide more environmentally balanced sources of energy and other non-food products than fossil fuels. Biomass utilization is in a precarious position, however, with public attention increasingly focused on both its potential and the strength of the challenges it faces. The paper is divided into five sections. Section 2 briefly addresses economic environmental issues. The extent to which externalities are accounted for in the market price of fuels plays a significant role in determining both the ultimate size of biofuel markets and the extent of the environmental benefits of feedstock cultivation and conversion processes. Sections 3 through 4 catalogue the main hazards and benefits that are likely to arise in the large scale commercialization of biomass fuel and note where the major uncertainties lay. Environmental issues arise with the cultivation of each feedstock and with each step in the process of its conversion to fuel. Feedstocks are discussed in Section 3 in terms of three main groups; wastes, energy crops, and traditional agricultural crops. In Section 4, conversion processes are also divided into three groups, on the basis of the end energy carrier; gas, liquid, and solid and electricity. Section 5 is devoted to a conclusion and summary

    Nair, S.K.N.; Mohan, Rakesh

    1998-01-01

    Financial distress alongside high rates of growth, stagnant organizations coexistent with upgraded technologies, richly endowed regions marked by low levels of electricity consumption and the long wait for private power in face of mounting shortfalls are among the contradictions marking the power sector. Decades of public financing support could shore up the rates of growth but forms of past intervention failed to address critical institutional and regulatory issues. Key areas that need intervention have now been identified, although several are yet to be tackled. This paper discusses the more important of the problem areas holding up significant economic gains that could be realized through cost reductions, the needed levels of investments, operation of market forces and targeting of resources to promote equitable growth. The slow pace of progress is a matter for concern. Effectiveness of many of the policy initiatives of government is also dependent on providing well thought out policy supports. (author)

  10. Issues related to the Fermion mass problem

    Murakowski, Janusz Adam

    1998-09-01

    This thesis is divided into three parts. Each illustrates a different aspect of the fermion mass issue in elementary particle physics. In the first part, the possibility of chiral symmetry breaking in the presence of uniform magnetic and electric fields is investigated. The system is studied nonperturbatively with the use of basis functions compatible with the external field configuration, the parabolic cylinder functions. It is found that chiral symmetry, broken by a uniform magnetic field, is restored by electric field. Obtained result is nonperturbative in nature: even the tiniest deviation of the electric field from zero restores chiral symmetry. In the second part, heavy quarkonium systems are investigated. To study these systems, a phenomenological nonrelativistic model is built. Approximate solutions to this model are found with the use of a specially designed Pade approximation and by direct numerical integration of Schrodinger equation. The results are compared with experimental measurements of respective meson masses. Good agreement between theoretical calculations and experimental results is found. Advantages and shortcommings of the new approximation method are analysed. In the third part, an extension of the standard model of elementary particles is studied. The extension, called the aspon model, was originally introduced to cure the so called strong CP problem. In addition to fulfilling its original purpose, the aspon model modifies the couplings of the standard model quarks to the Z boson. As a result, the decay rates of the Z boson to quarks are altered. By using the recent precise measurements of the decay rates Z → bb and Z /to [/it c/=c], new constraints on the aspon model parameters are found.

    2009-01-01

    There are a cluster of trends that reinforce the importance of nuclear power on the world scene. Energy is the essential underpinning for economic and societal progress and, as the developing world advances, the demand for energy is growing significantly. At the same time, the carbon-intensive sources of energy on which the world has traditionally relied - in particular, coal, oil, and natural gas - pose grave threats because the growing concentrations of carbon dioxide in the atmosphere will bring about climate and ocean acidification. At the same time, rising and volatile fossil fuel prices, coupled with concerns about the security of supplies of oil and gas, enhance interest in sources of energy that do not pose the same costs and risks. As an important part of the world's response to these threats, many countries are embarking on either new or expanded nuclear power programs, more commonly referred to as a nuclear renaissance. The construction of nuclear power plants is under consideration in over thirty countries that do not currently use nuclear power. For new entrants that may have experience in constructing and operating large-scale industrial and infrastructure projects, they may not be fully familiar with the unique requirements of nuclear power and may not be fully recognize the major commitments and understandings that they must assume. Additionally, an understanding of the full range of obligations may have diminished in those countries with only one or a few reactors and where nuclear construction has not been undertaken for a long time. It is therefore in the interest of all to ensure that every country with a nuclear power program has the resources, expertise, authority and capacity to assure safety in a complete and effective manner and is committed to doing so. This presentation will outline some of the more important national infrastructure considerations including nuclear safety issues for launching a nuclear power program. An update on the

    In the Netherlands there are two nuclear power plants. One 60Mw BWR for research purposes in Dodewaard, and one PWR 450 Mw IN Borssele. Both of these NPPs are undergoing an extensive upgrading. These plants use several CSS-like systems. These systems are primarily aimed to support and monitor safe and correct operation of the process or to detect specific (e.g. mechanical) problems in an early stage. The NPP in Dodewaard is upgrading its training simulator and process presentation system (''Datalogger''). The activities related to the CRP are mainly within the framework of the Dodewaard plant. This final national report will give an overview of these activities with particular emphasis on the replacement of the Datalogger system. Some additional information is given on trends in CSSs as used in fossil power plants. (author). 2 figs

    An ultra-wideband (UWB) bandpass filter with ultra-wide stopband based on a rectangular ring resonator is presented. The filter is designed for the operational frequency band from 4.10 GHz to 10.80 GHz with an ultra-wide stopband from 11.23 GHz to 40 GHz. The even and odd equivalent circuits are used to achieve a suitable analysis of the proposed filter performance. To verify the design and analysis, the proposed bandpass filter is simulated using full-wave EM simulator Advanced Design System and fabricated on a 20mil thick Rogers_RO4003 substrate with relative permittivity of 3.38 and a loss tangent of 0.0021. The proposed filter behavior is investigated and simulation results are in good agreement with measurement results.

Particularly, there are some specific initiatives that serve as guides to organizational decisions, which make their performance indicators for the context of corporate sustainability. 1) To explore the presence of work-related issues and their origins in corporate sustainability approach, analyzing a) corporate disclosures; b) sustainability guidelines that are identified as relevant in corporate disclosures; c) documents that are related to sustainable development and also identified as key-documents for these guidelines and initiatives. 2) To present the activity-centered ergonomics and psychodynamics of work contributions to work-related issues in a corporate sustainability approach. An exploratory study based on multiple sources of evidence that were performed from 2012 to 2013, including interviews with companies that engaged in corporate sustainability and document analysis using the content analysis approach. Work-related issues have been presented since the earliest sustainable development documents. It is feasible to construct an empirical framework for work-related issues and corporate sustainability approaches. 1) Although some authors argue that corporate sustainability has its roots based only on the environmental dimension, there is strong empirical evidence showing that social dimension aspects such as work-related issues have been present since the beginning. 2) Some indicators should be redesigned to more precisely translate the reality of some workplaces, particularly those indicators related to organizational design and mental health.

    Extraction of blood vessels on retinal images plays a significant role for screening of different opthalmologic diseases. However, accurate extraction of the entire and individual type of vessel silhouette from the noisy images with poorly illuminated background is a complicated task. To this aim, an integrated system design platform is suggested in this work for vessel extraction using a sequential bandpass filter followed by fuzzy conditional entropy maximization on matched filter response. At first noise is eliminated from the image under consideration through curvelet based denoising. To include the fine details and the relatively less thick vessel structures, the image is passed through a bank of sequential bandpass filter structure optimized for contrast enhancement. Fuzzy conditional entropy on matched filter response is then maximized to find the set of multiple optimal thresholds to extract the different types of vessel silhouettes from the background. Differential Evolution algorithm is used to determine the optimal gain in bandpass filter and the combination of the fuzzy parameters. Using the multiple thresholds, retinal image is classified as the thick, the medium and the thin vessels including neovascularization. Performance evaluated on different publicly available retinal image databases shows that the proposed method is very efficient in identifying the diverse types of vessels. Proposed method is also efficient in extracting the abnormal and the thin blood vessels in pathological retinal images. The average values of true positive rate, false positive rate and accuracy offered by the method is 76.32%, 1.99% and 96.28%, respectively for the DRIVE database and 72.82%, 2.6% and 96.16%, respectively for the STARE database. Simulation results demonstrate that the proposed method outperforms the existing methods in detecting the various types of vessels and the neovascularization structures. The combination of curvelet transform and tunable bandpass

    This article presents a novel band-pass filter for Fourier transform profilometry (FTP) for accurate 3-D surface reconstruction. FTP can be employed to obtain 3-D surface profiles by one-shot images to achieve high-speed measurement. However, its measurement accuracy has been significantly influenced by the spectrum filtering process required to extract the phase information representing various surface heights. Using the commonly applied 2-D Hanning filter, the measurement errors could be up to 5-10% of the overall measuring height and it is unacceptable to various industrial application. To resolve this issue, the article proposes an elliptical band-pass filter for extracting the spectral region possessing essential phase information for reconstructing accurate 3-D surface profiles. The elliptical band-pass filter was developed and optimized to reconstruct 3-D surface models with improved measurement accuracy. Some experimental results verify that the accuracy can be effectively enhanced by using the elliptical filter. The accuracy improvement of 44.1% and 30.4% can be achieved in 3-D and sphericity measurement, respectively, when the elliptical filter replaces the traditional filter as the band-pass filtering method. Employing the developed method, the maximum measured error can be kept within 3.3% of the overall measuring range.

  20. Dynamical consequences of bandpass feedback loops in a bacterial phosphorelay.

    Directory of Open Access Journals (Sweden)

    Shaunak Sen

    Full Text Available Under conditions of nutrient limitation, Bacillus subtilis cells terminally differentiate into a dormant spore state. Progression to sporulation is controlled by a genetic circuit consisting of a phosphorelay embedded in multiple transcriptional feedback loops, which is used to activate the master regulator Spo0A by phosphorylation. These transcriptional regulatory interactions are "bandpass"-like, in the sense that activation occurs within a limited band of Spo0A∼P concentrations. Additionally, recent results show that the phosphorelay activation occurs in pulses, in a cell-cycle dependent fashion. However, the impact of these pulsed bandpass interactions on the circuit dynamics preceding sporulation remains unclear. In order to address this question, we measured key features of the bandpass interactions at the single-cell level and analyzed them in the context of a simple mathematical model. The model predicted the emergence of a delayed phase shift between the pulsing activity of the different sporulation genes, as well as the existence of a stable state, with elevated Spo0A activity but no sporulation, embedded within the dynamical structure of the system. To test the model, we used time-lapse fluorescence microscopy to measure dynamics of single cells initiating sporulation. We observed the delayed phase shift emerging during the progression to sporulation, while a re-engineering of the sporulation circuit revealed behavior resembling the predicted additional state. These results show that periodically-driven bandpass feedback loops can give rise to complex dynamics in the progression towards sporulation.

    1993-07-01

    This document is a summary of the important issues involved in managing spent nuclear fuel (SNF) owned by the Department of Energy (DOE). Issues related to civilian SNF activities are not discussed. DOE-owned SNF is stored primarily at the Hanford Site, Idaho National Engineering Laboratory (INEL), Savannah River Site (SRS), Oak Ridge National Laboratory (ORNL), and West Valley Demonstration Project. Smaller quantities of SNF are stored at Brookhaven National Laboratory, Sandia National Laboratories, and Los Alamos National Laboratory (LANL). There is a wide variety of fuel types, including both low and high enrichment fuels from weapons production, DOE reactors, research and development programs, naval programs, and universities. Most fuel is stored in pools associated with reactor or reprocessing facilities. Smaller quantities are in dry storage. Physical conditions of the fuel range from excellent to poor or severely damaged. An issue is defined as an important question that must be answered or decision that must be made on a topic or subject relevant to achieving the complimentary objectives of (a) storing SNF in compliance with applicable regulations and orders until it can be disposed, and (b) safely disposing of DOE's SNF. The purpose of this document is to define the issues; no recommendations are made on resolutions. As DOE's national SNF management program is implemented, a system of issues identification, documentation, tracking, and resolution will be implemented. This document is an initial effort at issues identification. The first section of this document is an overview of issues that are common to several or all DOE facilities that manage SNF. The common issues are organized according to specific aspects of spent fuel management. This is followed by discussions of management issues that apply specifically to individual DOE facilities. The last section provides literature references

    1993-08-01

    An option that utilities have for obtaining material is to procure the desired item(s) from another utility. There are several reasons utilities choose another utility as the procurement source including item obsolescence, prohibitive cost on the commercial market, and excessive lead time. This document provides information on the technical, quality, and commercial issues which utilities may need to address when selling material to or procuring material from other utilities. This report provides suggested approaches for each of the following technical and quality issues: Design considerations; item acceptability considerations; original supplier considerations; commercial grade item dedication considerations; reportability considerations; packaging, shipping, and storage considerations; documentation considerations; receipt inspection considerations. The information is provided primarily for the inter-utility transfer of safety-related material. Several of the topics, however, may also apply to the transfer of non-safety-related material. The report also provides considerations on commercial issues which may be addressed during the inter-utility transfer of materials

    2008-12-01

    Bowlby's concept of mental working models of self, attachment figures, and the social world has been theoretically generative as a bridge between early relational experience and the beliefs and expectations that color later relationships. Contemporary attachment researchers, following his example, are applying new knowledge of children's conceptual development to their study of attachment-related mental representations in children and adults. The contributors to this special issue highlight recent advances in how the mental representations arising from attachment security should be conceptualized and studied, and identify a number of important directions for future work. This paper introduces the special issue by summarizing the major ideas of Bowlby and his followers concerning the nature and development of mental working models, points of theoretical clarity and uncertainty, and challenges in assessing these representations, as well as profiling each of the contributions to this issue.

    Full Text Available A simple and compact 4.9 GHz bandpass filter for C-band applications is proposed. This paper presents a novel microstrip cross-coupled interdigital half-wavelength stepped impedance resonator (SIR based bandpass filter (BPF.The designed structure is similar to that of a combination of two parallel interdigital capacitors. The scattering parameters of the structure are measured using vector network analyzer (VNA. The self generated capacitive and inductive reactances within the interdigital resonators exhibited in a resonance frequency of 4.9 GHz. The resonant frequency and bandwidth of the capacitive cross-coupled resonator is directly optimized from the physical arrangement of the resonators. The measured insertion loss (S21 and return loss (S11 were 0.3 dB and 28 dB, respectively, at resonance frequency which were almost close to the simulation results.

    1988-03-01

    Residual inventories of special nuclear materials (SNM) remaining in processing facilities (holdup) are recognized as an insidious problem for both safety and safeguards. This paper identifies some of the issues that are of concern to the safeguards community at-large that are related to holdup of SNM in large-scale process equipment. These issues range from basic technologies of SNM production to changing regulatory requirements to meet the needs of safeguarding nuclear materials. Although there are no magic formulas to resolve these issues, there are several initiatives that could be taken in areas of facility design, plant operation, personnel training, SNM monitoring, and regulatory guidelines to minimize the problems of holdup and thereby improve both safety and safeguards at nuclear material processing plants. 8 refs

  14. Trade-related Electronic Commerce Issues in the OECD

    Chang-In Yoon

    1998-12-01

    Full Text Available The trade committee of Organization for Economic Cooperation and Development (OECD has begun the study of the trade related to electronic commerce since 1997. The scale of the study on one hand has avoided the fact of copy and duplication of WTO and its organizational principles, on the other hand it has played a supplementary and supportive function. At present, digital-related product, such as computers, software and travel is the key point to the trade which resorts to electronic commerce. It is predicted that this trend will go on. The study on electronic commerce could be summed up into three main components: First, according to the phase of the trade, it could be divided into advertisement, purchase, delivery and payment. Second, issues on electronic commerce in the international trade; such as the issue that leads to the unfairness and non-neutrality of the searching engine in international service trade. Besides, domain name, trademarks and the issue of middleman which exist at the moment in the electronic commerce are activated and will also be discussed. Third, issues of the trade policy related to the electronic commerce. For instance, the kernel principles which support the multi-trade regulation, including transparency, indiscrimination, anti-dumping, flexible trade, government arrangement, tariff and competition policy and so on. Under this background, we should explore way in formulating hypotheses with preconceived issues, validating the electronic commerce trade on the spot, actualizing the study on the application of electronic commerce coming with the GATS regulation, seeking the countermeasure in the future trade policy, such as benefit policy to the electronic commerce department and electronic commerce strategy approach of certain enterprises, etc.

  15. Assistance to States on Policies Related to Wind Energy Issues

    2005-07-15

    This final report summarizes work carried out under agreement with the US Department of Energy, related to wind energy policy issues. This project has involved a combination of outreach and publications on wind energy, with a specific focus on educating state-level policymakers. Education of state policymakers is vitally important because state policy (in the form of incentives or regulation) is a crucial part of the success of wind energy. State policymakers wield a significant influence over all of these policies. They are also in need of high quality, non-biased educational resources which this project provided. This project provided outreach to legislatures, in the form of meetings designed specifically for state legislators and legislative staff, responses to information requests on wind energy, and publications. The publications addressed: renewable energy portfolio standards, wind energy transmission, wind energy siting, case studies of wind energy policy, avian issues, economic development, and other related issues. These publications were distributed to legislative energy committee members, and chairs, legislative staff, legislative libraries, and other related state officials. The effect of this effort has been to provide an extensive resource of information about wind information for state policymakers in a form that is useful to them. This non-partisan information has been used as state policymakers attempt to develop their own policy proposals related to wind energy in the states.

    The paper discusses the legal issues related to the Ontario FIT contract, which includes the FIT waiver agreement, WTO challenge, FIT extension, political risk assessment and issues related to unforeseen events beyond human control (force majeure). The risk of termination of the FIT waiver is omitted for convenience by OPA but timing implications relating to the FIT waiver are included. The binding agreement for supply of generating equipment is also presented and the term sheet for turbine equipment and bill of purchase being understood as binding agreements is questioned. Political risks relate to existing contracts, lawsuit risks and changes to the REA process. Change in government and the implications of minority government can be added to the political risks. A successful WTO challenge has been assumed and the possible implications are discussed. Some of them include risk to FIT contracts already issued; changes in DC requirements and in FIT contract pricing and re-pricing of construction and turbine equipment supply contracts if DC requirements are relaxed.

    2000-01-01

    The Agency has included activities on research reactor safety in its Programme and Budget (P and B) since its inception in 1957. Since then, these activities have traditionally been oriented to fulfil the Agency's functions and obligations. At the end of the decade of the eighties, the Agency's Research Reactor Safety Programme (RRSP) consisted of a limited number of tasks related to the preparation of safety related publications and the conduct of safety missions to research reactor facilities. It was at the beginning of the nineties when the RRSP was upgraded and expanded as a subprogramme of the Agency's P and B. This subprogramme continued including activities related to the above subjects and started addressing an increasing number of issues related to the current situation of research reactors (in operation and shut down) around the world such as reactor ageing, modifications and decommissioning. The present paper discusses some of the above issues as recognised by various external review or advisory groups (e.g., Peer Review Groups under the Agency's Performance Programme Appraisal System (PPAS) or the standing International Nuclear Safety Advisory Group (INSAG)) and the impact of their recommendations on the preparation and implementation of the part of the Agency's P and B relating to the above subject.

    2017-07-01

    In this paper, a novel microwave continuously tunable band-pass filter, based on nematic liquid crystals (LCs), is proposed. It uses liquid crystal (LC) as the electro-optic material to mainly realize frequency shift at microwave band by changing the dielectric anisotropy, when applying the bias voltage. According to simulation results, it achieves 840 MHz offset. Comparing to the existing tunable filter, it has many advantages, such as continuously tunable, miniaturization, low processing costs, low tuning voltage, etc. Thus, it has shown great potentials in frequency domain and practical applications in modern communication.

  6. Plasmonic Band-Pass Microfilters for LWIR Absorption Spectroscopy

    Directory of Open Access Journals (Sweden)

    J. M. Banks

    2012-01-01

    Full Text Available Absorption spectroscopy in the long wave infrared provides an effective method for identification of various hazardous chemicals. We present a theoretical design for plasmonic band-pass filters that can be used to provide wavelength selectivity for uncooled microbolometer sensors. The microfilters consist of a pair of input reflection gratings that couple light into a plasmonic waveguide with a central resonant waveguide cavity. An output transmission grating on the other side of the structure pulls light out of the waveguide where it is detected by a closely spaced sensor. Fabrication of the filters can be performed using standard photolithography procedures. A spectral bandpass with a full-width at half-maximum (FWHM of 100 nm can be obtained with a center wavelength spanning the entire 8–12 μm atmospheric transmission window by simple geometric scaling of only the lateral dimensions. This allows the simultaneous fabrication of all the wavelength filters needed for a full spectrometer on a chip.

    2003-01-01

    The conventional logic gate architecture is not suitable for high-density integration of quantum devices which are non-robust and extremely structure- and charge-sensitive. In this paper, our novel hexagonal binary-decision-diagram (BDD) quantum circuit approach for III-V nanoelectronics is reviewed and related critical surface/interface issues for high-density integration are discussed. First, the basic concept and actual implementation method of our approach are explained, giving examples of novel BDD quantum integrated circuits where nanowire networks are controlled by nanoscale Schottky wrap gates. For high-density integration, growth of embedded sub-10 nm III-V quantum wire networks by selective molecular beam epitaxy (MBE) on patterned substrates is described, including effects of atomic hydrogen irradiation and kinetic control of wire width. The key processing issue lies in understanding and control of nanostructure surfaces/interfaces. Behavior of nanoscale Schottky gates, recent scanning tunneling microscopy (STM)/scanning tunneling spectroscopy (STS) studies of surface states, and successful removal of surface states by MBE-grown silicon interface control layer are discussed

  8. Ethical issues related to epilepsy care in the developing world.

    Tan, Chong-Tin; Avanzini, Giuliano

    2009-05-01

    There are three major issues of ethical concern related to epilepsy care in the developing world. First, is it ethical for a developing country to channel its limited resources from direct epilepsy care to research? The main considerations in addressing this question are the particular research questions to be addressed and whether such research will bring direct benefits to the local community. Second, in a country with limited resources, when does ignoring the high treatment gap become an ethical issue? This question is of particular concern when the community has enough resources to afford treatment for its poor, yet is not providing such care because of gross wastage and misallocation of the national resources. Third, do countries with plentiful resources have an ethical responsibility to help relieve the high epilepsy treatment gap of poor countries? Indeed, we believe that reasonable health care is a basic human right, and that human rights transcend national boundaries. Although health care is usually the responsibility of the nation-state, many modern states in the developing world are arbitrary creations of colonization. There is often a long process from the establishment of a political-legal state to a mature functional nation. During the long process of nation building, help from neighboring countries is often required.

    The migration process may impose stress on the mental health of immigrants. To describe the experiences of immigrant men of Kurdish ethnicity during and after migration to Sweden with regard to mental health issues. Using the grounded theory method, we conducted a focus group interview with four Kurdish men and in-depth individual interviews with 10 other Kurdish men. A model with two major themes and interlinked categories was developed. The themes were (1) protective factors for good mental health (sense of belonging, creation and re-creation of Kurdish identity, sense of freedom, satisfaction with oneself) and (2) risk factors for poor mental health (worry about current political situation in the home country, yearning, lack of sense of freedom, dissatisfaction with Swedish society). The study provides insights into the psychological and emotional experiences of immigrant men of Kurdish ethnicity during and after migration to Sweden. It is important for primary health care providers to be aware of the impact that similar migration-related and life experiences have on the health status of immigrants, and also to be aware that groups are comprised of unique individuals with differing experiences and reactions to these experiences. The findings highlight the common themes of the men's experiences and suggest ways to ameliorate mental health issues, including feeling like one is seen as an individual, is a full participant in society, and can contribute to one's own culture.

    In order to make fusion power a viable future source of energy, it will be necessary to ensure that the cost of power for fusion electric generation is competitive with advanced fission concepts. In addition, fusion power will have to live up to its original promise of being a more radiologically benign technology than fission, and be able to demonstrate excellent operational safety performance. These two requirements are interrelated, since the selection of an appropriate safety philosophy early in the design phase could greatly reduce or eliminate the capital costs of elaborate safety related and protective sytems. This paper will briefly overview a few of the key safety issues presently recognized as critical to the ultimate achievement of licensable, environmentally safe and socially acceptable fusion power facilities. 12 refs

  11. Effect of splenectomy on liver cirrhosis and related surgical issues

    Full Text Available Patients with liver fibrosis and cirrhosis experience certain changes in spleen morphology and function, and there is always a controversy over whether to perform splenectomy in patients with liver cirrhosis. As a surgical treatment of recurrent portal hypertension complicated by esophagogastric variceal bleeding, splenectomy can reduce portal venous pressure, reduce the possibility of gastrointestinal bleeding, and correct the reduced white blood cell count and platelet count. It can also protect the liver by improving liver function, promoting regeneration of hepatocytes, and inhibiting the progression of liver fibrosis. With reference to available clinical and laboratory data, this article reviews the effect of splenectomy on the cirrhotic liver and related issues such as selection of surgical procedures and prevention and treatment of postoperative complications, in order to promote splenectomy in patients with liver cirrhosis.

    The use of hunger strike as a tool to assert grievances has been around for ages and has occasionally happened in the world. Hunger strikers' motives may differ, but their tool is the same--the voluntary refusal of food. Fasting not only results in body weight loss, but also in physiological and neurological function changes, and, of course, it may even threaten life. The health care of hunger strikers is complex. It involves medical staff, medical ethics and guidance for the management of the hunger strikers. Improper medical management may not only undermine the hunger striker's dignity but also risk further damage to his or her health. By understanding hunger strikers' physiological changes and related ethical issues, therefore, we aim to identify appropriate forms of nursing care management and guidance for the care of hunger strikers.

  13. Miniaturized and Ferrite Based Tunable Bandpass Filters in LCP and LTCC Technologies for SoP Applications

    KAUST Repository

    Arabi, Eyad A.

    2015-04-01

    Wireless systems with emerging applications are leaning towards small size, light-weight and low cost. Another trend for these wireless devices is that new applications and functionalities are being added without increasing the size of the device. To accomplish this, individual components must be miniaturized and the system should be designed to maximize the integration of the individual components. The high level of 3D integration feasible in system on package design (SoP) concept can fulfill the latter requirement. Bandpass filters are important components on all wireless systems to reject the unwanted signals and reduce interference. Being mostly implemented with passive and distributed components, bandpass filters take considerable space in a wireless system. Moreover, with emerging bands and multiple applications encompassed in a single device, many bandpass filters are required. The miniaturization related to bandpass filters can be approached by three main ways: (1) at the component level through the miniaturization of individual bandpass filters, (2) at the system level through the use of tunable filters to reduce the overall number of filters, and (3) at the system level through the high level of integration in a 3D SoP platform. In this work we have focused on all three aspects of miniaturization of band pass filters mentioned above. In the first part of this work, a low frequency (1.5 GHz global positioning system (GPS) band) filter implemented through 3D lumped components in two leading SoP technologies, namely low temperature co-fired ceramic (LTCC) and the liquid crystal polymers (LCP) is demonstrated. The miniaturized filter is based on a second order topology, which has been modified to improve the selectivity and out-of-band rejection without increasing the size. Moreover, for the case of LCP, the filter is realized in an ultra-thin stack up comprising four metallization layers with an overall thickness of only 100 _m. Due to its ultra

    Emissions of CO2 from the energy and land-use change and forestry sectors are responsible for the majority of emissions in non-Annex I Parties to the UNFCCC. Tackling greenhouse gas (GHG) emissions from these sectors is a key to slowing the growth in GHG emissions in non-Annex I countries. Implementing Clean Development Mechanism (CDM) projects can help achieve this aim, while also assisting non-Annex I countries to move towards sustainable development and Annex I countries achieve their emission commitments under the Kyoto Protocol. There has been rapid progress in the CDM over the last year - in terms of the number of projects in the pipeline and registered, and in terms of credits issued. However, some important sectors are notable by their small share in the CDM portfolio. Several countries have also called attention to the need to accelerate the process of approving CDM methodologies and projects. In order to improve the effectiveness of the CDM to achieve its dual objectives, the COP/MOP agreed a decision on 'further guidance relating to the clean development mechanism. This decision lays out guidance on how to improve the operation of the CDM, and includes provisions that allow: (1) Bundling of project activities; and (2) Project activities under a programme of activities, to be registered as a CDM project activity. At present, of the 172 currently registered CDM project activities, 27 involve programmes or bundles. These project activities can include more than one project type, be implemented in several locations, and/or occur in more than one sector. This paper assesses how project activities under a programme of activities under the CDM (referred to here as PCDM) could help to increase the effectiveness of the CDM by encouraging a wide spread of emission mitigation activities. This paper also explores the key issues that may need to be considered for the PCDM concept to be further implemented. The paper concludes that: (1) Key concepts and issues

    A critical issue in the quality assurance of safety-related software is the ability of the software to produce identical results, independent of the host machine, operating system, or compiler version under which the software is installed. A study is performed using the VIPRE-0l, FREY-01, and RETRAN-02 safety-related codes. Results from an IBM 3083 computer are compared with results from a CYBER 860 computer. All three of the computer programs examined are written in FORTRAN; the VIPRE code uses the FORTRAN 66 compiler, whereas the FREY and RETRAN codes use the FORTRAN 77 compiler. Various compiler options are studied to determine their effect on the output between machines. Since the Control Data Corporation and IBM machines inherently represent numerical data differently, methods of producing equivalent accuracy of data representation were an important focus of the study. This paper identifies particular problems in the automatic double-precision option (AUTODBL) of the IBM FORTRAN 1.4.x series of compilers. The IBM FORTRAN version 2 compilers provide much more stable, reliable compilation for engineering software. Careful selection of compilers and compiler options can help guarantee identical results between different machines. To ensure reproducibility of results, the same compiler and compiler options should be used to install the program as were used in the development and testing of the program

  16. Addressing security issues related to virtual institute distributed activities

    2008-03-01

    One issue confounding the development and experimentation of distributed modeling and simulation environments is the inability of the project team to identify and collaborate with resources, both human and technical, from outside the United States. This limitation is especially significant within the human behavior representation area where areas such as cultural effects research and joint command team behavior modeling require the participation of various cultural and national representatives. To address this limitation, as well as other human behavior representation research issues, NATO Research and Technology Organization initiated a project to develop a NATO virtual institute that enables more effective and more collaborative research into human behavior representation. However, in building and operating a virtual institute one of the chief concerns must be the cyber security of the institute. Because the institute "exists" in cyberspace, all of its activities are susceptible to cyberattacks, subterfuge, denial of service and all of the vulnerabilities that networked computers must face. In our opinion, for the concept of virtual institutes to be successful and useful, their operations and services must be protected from the threats in the cyber environment. A key to developing the required protection is the development and promulgation of standards for cyber security. In this paper, we discuss the types of cyber standards that are required, how new internet technologies can be exploited and can benefit the promulgation, development, maintenance, and robustness of the standards. This paper is organized as follows. Section One introduces the concept of the virtual institutes, the expected benefits, and the motivation for our research and for research in this area. Section Two presents background material and a discussion of topics related to VIs, uman behavior and cultural modeling, and network-centric warfare. Section Three contains a discussion of the

  17. High-Q Bandpass Comb Filter for Mains Interference Extraction

    2009-12-01

    Full Text Available This paper presents a simple digital high-Q bandpass comb filter for power-line (PL or other periodical interference extraction. The filter concept relies on a correlated signal average resulting in alternating constructive and destructive spectrum interference i.e. the so-called comb frequency response. The presented filter is evaluated by Matlab simulations with real ECG signal contaminated with low amplitude PL interference. The made simulations show that this filter accurately extract the PL interference. It has high-Q notches only at PL odd harmonics and is appropriate for extraction of any kind of odd harmonic interference including rectangular shape. The filter is suitable for real-time operation with popular low-cost microcontrollers.

  18. Pain-related psychological issues in hand therapy.

    Science.gov (United States)

    Hamasaki, Tokiko; Pelletier, René; Bourbonnais, Daniel; Harris, Patrick; Choinière, Manon

    Literature review. Pain is a subjective experience that results from the modulation of nociception conveyed to the brain via the nervous system. Perception of pain takes place when potential or actual noxious stimuli are appraised as threats of injury. This appraisal is influenced by one's cognitions and emotions based on her/his pain-related experiences, which are processed in the forebrain and limbic areas of the brain. Unarguably, patients' psychological factors such as cognitions (eg, pain catastrophizing), emotions (eg, depression), and pain-related behaviors (eg, avoidance) can influence perceived pain intensity, disability, and treatment outcomes. Therefore, hand therapists should address the patient pain experience using a biopsychosocial approach. However, in hand therapy, a biomedical perspective predominates in pain management by focusing solely on tissue healing. This review aims to raise awareness among hand therapists of the impact of pain-related psychological factors. This literature review allowed to describe (1) how the neurophysiological mechanisms of pain can be influenced by various psychological factors, (2) several evidence-based interventions that can be integrated into hand therapy to address these psychological issues, and (3) some approaches of psychotherapy for patients with maladaptive pain experiences. Restoration of sensory and motor functions as well as alleviating pain is at the core of hand therapy. Numerous psychological factors including patients' beliefs, cognitions, and emotions alter their pain experience and may impact on their outcomes. Decoding the biopsychosocial components of the patients' pain is thus essential for hand therapists. Copyright © 2018 Hanley & Belfus. Published by Elsevier Inc. All rights reserved.

    Bart L. Rottier

    2015-06-01

    Full Text Available Management-related issues are an important aspect of monitoring asthma in children in clinical practice. This review summarises the literature on practical aspects of monitoring including adherence to treatment, inhalation technique, ongoing exposure to allergens and irritants, comorbid conditions and side-effects of treatment, as agreed by the European Respiratory Society Task Force on Monitoring Asthma in Childhood. The evidence indicates that it is important to discuss adherence to treatment in a non-confrontational way at every clinic visit, and take into account a patient's illness and medication beliefs. All task force members teach inhalation techniques at least twice when introducing a new inhalation device and then at least annually. Exposure to second-hand tobacco smoke, combustion-derived air pollutants, house dust mites, fungal spores, pollens and pet dander deserve regular attention during follow-up according to most task force members. In addition, allergic rhinitis should be considered as a cause for poor asthma control. Task force members do not screen for gastro-oesophageal reflux and food allergy. Height and weight are generally measured at least annually to identify individuals who are susceptible to adrenal suppression and to calculate body mass index, even though causality between obesity and asthma has not been established. In cases of poor asthma control, before stepping up treatment the above aspects of monitoring deserve closer attention.

    2015-01-01

    In the course of our professional experience, we have seen that many medical students plagiarise. We hypothesised that they do so out of ignorance and that they require formal education on the subject. With this objective in mind, we conducted a teaching session on issues related to plagiarism. As a part of this, we administered a quiz to assess their baseline knowledge on plagiarism and a questionnaire to determine their attitudes towards it. We followed this up with an interactive teaching session, in which we discussed various aspects of plagiarism. We subjected the data obtained from the quiz and questionnaire to bivariate and multivariate analysis. A total of 423 medical students participated in the study. Their average score for the quiz was 4.96±1.67 (out of 10). Age, gender and years in medical school were not significantly associated with knowledge regarding plagiarism. The knowledge scores were negatively correlated with permissive attitudes towards plagiarism and positively correlated with attitudes critical of the practice. Men had significantly higher scores on permissive attitudes compared to women . In conclusion, we found that the medical students' knowledge regarding plagiarism was limited. Those with low knowledge scores tended to have permissive attitudes towards plagiarism and were less critical of the practice. We recommend the inclusion of formal instruction on this subject in the medical curriculum, so that this form of academic misconduct can be tackled.

    Primary copper production is a major activity in the mining sector of several countries. However, it is highly energy-intensive and poses important environmental hazards. In the case of Chile, the world's largest copper producer (40% of world total), we examine its energy consumption and energy-related environmental implications over a time horizon of 25 years. Concerning the latter, we focus on greenhouse-gas (GHG) emissions, one of the most debated environmental issues. This paper follows up our previous report in which the current situation was analyzed and a particular technical option for improving the energy efficiency and concurrently reducing GHG emissions was discussed. Estimated reference or base (BS) and mitigation (MS) scenarios are developed for the period ending in 2020. The former assesses the energy demand projected in accordance with production forecasts and specific energy consumption patterns (assuming that energy efficiency measures are adopted 'spontaneously') with their resultant GHG emissions, while the latter assumes induced actions intended to reduce emissions by adopting an aggressive policy of efficient energy use. For the year 2020, the main results are: (i) BS, 1214 t of CO{sub 2}/ton of refined copper content (49% lower than in 1994); (ii) MS, 1037 t of CO{sub 2}/t of refined copper content (56% lower than in 1994). CO{sub 2} emissions have been estimated considering both fuel and electricity process requirements. (author)

    2018-01-01

    Full Text Available Atmospheric environment affects the materials of historic monuments and their structure starting from the time of their construction. Daily and seasonal changes in temperature and humidity, wind, snow and rainfall, soluble salts carried by water, biological agents, pollutant gases and particulate matter are some of the agents in atmospheric environment that introduce weathering by physical, chemical and biological processes in the materials of the monuments such as natural building stones, bricks, mortars and plasters, mud brick etc. The weathering processes need to be well diagnosed by identification of main mechanisms of decay and major responsible agents, degree and depth of deterioration expressed with measurable parameters of physical, physicomechanical properties, and micro structural changes together with their distribution on the monument. Success of conservation treatments strongly depend on those diagnostic studies and compatibility of the treatments with the deteriorated and relatively sound parts of the historic materials. Current approach to materials conservation is to be able to make minimum intervention to historic material by targeting the conservation treatment to the deteriorated area for the purpose of controlling the deterioration factors and achieving compatible and durable conservation of historical material. In this presentation, two examples of diagnostic research and conservation treatments based on and guided by the diagnostic results are summarized concerning historic stone monuments exposed to atmospheric environment since more than two thousand years. The first example is on the marble walls of Temple of Augustus in Ankara exposed to polluted urban atmosphere. The second example is on the limestone statues of Nemrut Mount Monument in Adıyaman-Turkey, exposed to rural atmosphere with harsh climatic conditions. Finally, a brief discussion on current research issues related to historic materials conservation in

    Nirex has undertaken various consultations with different stakeholders to identify their issues and concerns about radioactive waste management in general and specific aspects of Nirex's work. This paper will outline what dialogue techniques Nirex has undertaken and the issues and concerns that people have raised during the events. It will outline some of the work that Nirex is undertaking to address stakeholders' issues and concerns. Nirex has used a variety of dialogue techniques co-ordinated under the Nirex Involvement Programme to engage with stakeholders about the work we undertake. We are now trying to address the issues, concerns, scenarios and questions raised in our work programme. Key lessons that we have learned in undertaking the dialogues include: The importance of appropriate facilitation and organisation of meetings; The need for a clear purpose for meetings; Being flexible to the needs of the attendees and the issues they raise; Providing feedback to those who participate and following up issues. Through engaging with the public Nirex has learned that: Radioactive waste is not an everyday concern for people; The public can, will and want to engage with the issue of radioactive waste management. This includes engaging with the ethical debate. To facilitate this Nirex and others need to: Provide information in a neutral form outlining the pros and cons and including various people's opinions; Use proactive techniques to allow access and space for people to discuss the issues; Demonstrate how people's opinions have been taken into account. People understand the issues very differently to the way institutions understand them. There is a need for institutions to learn to understand public concerns and the ways in which the public understand issues, as well as for the public to understand the institutional positions better. We are using these insights to develop our future work in this area

  11. LABOUR MARKET INTEGRATION ISSUES RELATED TO MIGRANTS ARRIVING TO HUNGARY

    Directory of Open Access Journals (Sweden)

    Peter Miklos Komives

    2016-07-01

    Full Text Available The migration flows appearing in the recent years have gained central relevance in Hungary. Previously people were having no opinion about the current situation of issues related to migration but the increased media attention lead to the development of mixed attitudes among people. Some people feel sorry for the families who are coming from the war zones and lost their homes, others have fear of losing their position at work, or their families because of the acts they have heard from the media and they are hostile to the issue of integration whether it is about education or the labour market. According to the statistical data; in the third quarter of 2015, more than hundred thousand asylum-seekers arrived to Hungary, which dropped drastically in the fourth quarter caused by the significant transformation of the asylum process. This study is intended to serve two objectives: first describe the comprehensive picture of labour market attitudes towards migrants and secondly to identify factors that affect the employment of foreigners in Hungary using secondary data sources. Based on this analysis those questions can be formulated, which may constitute a basis for further labour market researches for the integration of migrants. From our point of view there are vital aspects of the migrants’ successful social integration; we have to integrate the migrants who are coming to our country and plan to stay for a longer time to the field of education and the labour market. The social integration of migrants in a country is closely linked to employment, to the integration into the labour market, and in many cases one of the obstacles in this regard is the prejudiced behaviour and negative attitudes towards migrants which manifests itself as the discrimination in the labour market. The results of the European Commission confirm that in Hungary the ethnicity as a variable appears to be the second on the list of the most serious discrimination factors

    The report is devoted to presentation of engineering approach and software tool developed for Safety Culture (SC) assessment as well as to the results of their implementation at Smolensk NPP. The engineering approach is logic evolution of the IAEA ASSET method broadly used at European NPPs in 90-s. It was implemented at Russian and other plants including Olkiluoto NPP in Finland. The approach allows relative quantitative assessing and trending the aspects of SC by the analysis of evens features and causes, calculation and trending corresponding indicators. At the same time plant's operational performances and related social issues, including efficiency of plant operation and personnel reliability, can be monitored. With the help of developed tool the joint team combined from personnel of Smolensk NPP and RRC 'Kurchatov Institute' ('KI') issued the SC self-assessment report, which identifies: families of recurrent events, main safety and operational problems ; their trends and importance to SC and plant efficiency; recommendations to enhance SC and operational performance

    The establishment of a federal security force has been suggested as an additional step to protect nuclear material. The force would be given the responsibility for guarding nuclear facilities and shipments of nuclear materials. A study to identify the issues that are relevant to choosing between the private guard forces that are presently employed by industry or a guard force under federal authority is summarized. To examine the issues which would be relevant, three possible types of security force structures were selected for comparison: a federal force under central authority, a private guard force employed by or under contract to a facility, and a private arrangement to employ local police officers similar to the arrangement for armed guards at airports. The issues were divided into seven categories: (1) legal considerations, (2) liability, (3) staffing and operations, (4) costs, (5) relationship to off-site forces, (6) management and control, and (7) transportation.

    This volume is unusual in that the theme is quite broad in scope yet focused on a specific topic; innovations and boundary-pushing studies in areas not usually found in library literature. It examines the periphery of the field surveyed in previous volumes. The chapters are grouped in two categories: professional issues and transforming services.

  2. Review of spent fuel related issues in SKB's SR 97

    International Nuclear Information System (INIS)

    Grambow, B.

    2000-01-01

    The solid waste form 'spent fuel' constitutes both the dominant radionuclide source as well as a first radionuclide retention barrier of a planned future high level nuclear waste isolation systems in deep granite formations. In order to evaluate the performance of spent fuel as part of the multibarrier containment system in a deep repository, the radionuclide release properties in groundwater must be predicted over very long time periods. Radionuclide release is not an inherent materials property of the fuel but depends, besides fuel specific parameters, mainly on time but as well on the geochemical and hydraulic environment of the disposal location. The study SR 97 documents the large effort of SKB to assess the long-term performance of a repository containing spent nuclear fuel. Scenario and consequence analyses are clearly described, considering major physical and chemical interactions of the various components of the multi-barrier isolation system. The approach attempts to assess both a realistic and a pessimistic evolution scenario. The present report attempts to evaluate whether this approach is thoroughly carried through to assess the performance of spent nuclear fuel in a repository. Main issues are radionuclide inventories and inventory distribution between structural parts of the fuel assembly and the fuel matrix, potential fuel alteration prior to water access, as well as models for fuel matrix dissolution and instant release fractions. Uncertainties in radionuclide inventories are discussed and were found for many radionuclides to be higher than assumed in SR 97. This is particularly true for Cl-36. This nuclide is a potential key biosphere dose contributor in various international safety assessments. Of particular importance are uncertainties related to the partition of radionuclides between metallic parts of the fuel assembly and the fuel matrix, since inventories of metallic parts are considered to be released instantaneously.

    To review issues regarding the use of genetic materials and information. Professional literature, regional and federal legislation. An analysis is provided of the relationship among advances in genetic technology, use of genetic material and information, and the development of laws that protect the interests of donors, researchers, and insurers. Rapid technological achievements have generated complex questions that are difficult to answer. The Human Genome Project began and the scientific discoveries were put to use before adequate professional and public debate on the ethical, legal, social, and clinical issues. The term "proper use" of genetic material and information is not defined consistently. An incomplete patchwork of protective state and federal legislation exists. Many complicated issues surround the use and potential misuse of genetic material and information. Rapidly advancing technology in genetics makes it difficult for regulations that protect individuals and families to keep pace. Oncology nurses need to recognize their role as change agents, understand genetic technology, and advocate for patients by participating in the debate on the proper use and prevention of misuse of genetic material and information.

  5. LEGAL ISSUES RELATED TO THE SHARIAH ADVISORY COUNCIL IN MALAYSIA

    Directory of Open Access Journals (Sweden)

    2013-08-01

    Full Text Available Malaysia has always aspired to be the hub for Islamic banking and finance. Various measures have been, and are being, carried out to promote Malaysia as an international Islamic banking and financial centre. As the backbone for this, the national Shariah Advisory Council (SAC has been established under the auspices of the Central Bank of Malaysia Act 1958 (CBMA. Under the CBMA, the SAC has been conferred a statutory function as the authority for the ascertainment of Islamic law for the purposes of Islamic banking, as well as business and other types of Islamic financial businesses. In 2009, the CBMA 1958 was replaced and repealed. With the coming into force of the CBMA 2009, the role and functions of the SAC was reinforced and upgraded in terms of appointments of members and, most importantly, that the Shariah rulings pursuant to any reference made to the SAC by the Civil court or arbitrator concerning Shariah matters shall be binding on the Islamic financial institutions as well as on the court and any arbitrator. The issue of whether or not the SAC is the final arbiter on Islamic banking and finance disputes or, in other words, there is no longer a process of judicial review where it involves Shariah matters, will be the highlight of this paper. To what extent does the post CBMA 2009 solve the binding nature of the SAC upon the Civil courts of Malaysia as its rulings and directives are only relevant to ‘Shariah’ issues? What would be the situations if the issues of the Islamic banking and finance cases are deemed not to amount to a ‘Shariah’ issue, but are purely on banking, land matters or contractual interpretations? Has there any actual legal reform been brought about by this amendment or is it merely a cosmetic changes? If the court were to be bound by the SAC rulings, does this not usurp the independence of the judiciary which is the corner stone of the principle of separation of powers between the executive, the legislature and

    We experimentally demonstrate high-performance narrowband terahertz (THz) bandpass filters through cascading multiple bilayer metasurface antireflection structures. Each bilayer metasurface, consisting of a square array of silicon pillars with a self-aligned top gold resonator-array and a complementary bottom gold slot-array, enables near-zero reflection and simultaneously close-to-unity single-band transmission at designed operational frequencies in the THz spectral region. The THz bandpass filters based on stacked bilayer metasurfaces allow a fairly narrow, high-transmission passband, and a fast roll-off to an extremely clean background outside the passband, thereby providing superior bandpass performance. The demonstrated scheme of narrowband THz bandpass filtering is of great importance for a variety of applications where spectrally clean, high THz transmission over a narrow bandwidth is desired, such as THz spectroscopy and imaging, molecular detection and monitoring, security screening, and THz wireless communications.

  7. Dealing with quantum weirdness: Holism and related issues

    International Nuclear Information System (INIS)

    Elby, A.R.

    1995-12-01

    Various issues are discussed in interpretation of quantum mechanics. All these explorations point toward the same conclusion, that some systems are holistically connected, i.e., some composite systems have properties that cannot, even in principle, be reduced to the properties of its subsystems. This is argued to be the central metaphysical lesson of quantum theory; this will remain pertinent even if quantum mechanics gets replaced by a superior theory. Chap. 2 discusses nonlocality and rules out hidden-variable theories that approximately reproduce the perfect correlations of quantum mechanics, as well as theories that obey locality conditions weaker than those needed to derive Bell's inequality. Chap. 3 shows that SQUID experiments can rule out non-invasive measurability if not macrorealism. Chap. 4 looks at interpretational issues surrounding decoherence, the dissipative interaction between a system and its environment. Decoherence klcan help ''modal'' interpretations pick out the desired ''preferred'' basis. Chap. 5 explores what varieties of causation can and cannot ''explain'' EPR correlations. Instead of relying on ''watered down'' causal explanations, we should instead develop new, holistic explanatory frameworks

    Nuclear energy has always been a polemic issue, and it is usually more intensely associated, by the general public, to the risks than to the benefits from its use; in this sense, the mass media have clearly had its share of responsibility for public opinion formation. This paper presents a report on the coverage of the nuclear issue in the press, identifying the amount of negative and positive views on the subject, as well as the people involved in the process. The analysis comprises the period from February 2007 to February 2008, right after the edition of the 4th IPCC Report. From that sample, 172 texts published in widely known newspapers and magazines, most of them from Sao Paulo State, were identified. The analyzed speeches were classified according to five information sources: specialists, users, authorities, protagonists and entrepreneurs. It was noted the predominance of positive articles, mainly due to the weight of the favorable speeches by authorities, cited as the most frequent in this paper. (author)

    Antoniuk, T.

    1998-01-01

    This presentation discussed the environmental issues that petroleum companies face in northeast British Columbia. Petroleum exploration, development, production, abandonment and transportation activities in the province must follow provincial and federal regulations as well as government policies and guidelines which define environmental assessment, protection, and mitigation standards. A discussion about the regulatory framework in British Columbia can be found in the 'British Columbia Oil and Gas Handbook' which is available on the INTERNET at http://natural.gov.bc.ca/handpubs/oilgashb/bcoghb.htm. It was suggested that companies wishing to conduct drilling or exploration activities in sensitive areas should allow extra time (up to one year) to obtain approval for such activities. British Columbia's environmental setting includes five zones - the Alpine Tundra, the Spruce-Willow-Birch zone, the Engelmannn Spruce-Subalpine Fir forests, the Sub-Boreal Spruce zone, and the Boreal White and Black Spruce zone. Four discrete oil and gas guideline zones with differing standards have been developed. These are: (1) the Northern Rocky Mountains, (2) the Northeastern Slopes, (3) the Southeastern Slopes, and (4) the Northern Plains. A set of interim environmental guidelines are in effect to direct activity away from any sensitive area. Three sub-regional land use planning areas have also been established in the Prince George Forest Region which includes Dawson Creek, Fort St. John and Fort Nelson. Petroleum operators in these regions are obliged to deal with issues regarding aboriginal involvement, stream crossings, access management, and air quality. 40 refs

    Full Text Available Since its establishment the SCO has always attracted a lot of expert attention. The SCO Forum was founded in 2006 to bring together for annual debates experts from all member-states. Within this format in-depth discussions took place in April 2016 in Dushanbe, which hosted this year conference of the SCO Forum. Participating experts and officials reviewed problems of security, economic cooperation (including transport and water-energy issues and SCO enlargement, the latter being one of the most debatable. Experts presented some new thesis on all these problems, in particular on the enlargement issue. These new thesis are summed up in this article. Besides, the SCO Forum this year had many statements on the organization approaching a sort of new phase in its development. This line of discussions may lead in the future to even more active debates on SCO's role in the world. This article puts emphasis on the new elements of these debates and reviews major experts' attitudes within this line of discussion on the SCO being in front of a new stage of development.

  13. Auditory stream segregation using amplitude modulated bandpass noise

    2015-08-01

    Full Text Available The purpose of this study was to investigate the roles of spectral overlap and amplitude modulation (AM rate for stream segregation for noise signals, as well as to test the build-up effect based on these two cues. Segregation ability was evaluated using an objective paradigm with listeners’ attention focused on stream segregation. Stimulus sequences consisted of two interleaved sets of bandpass noise bursts (A and B bursts. The A and B bursts differed in spectrum, AM-rate, or both. The amount of the difference between the two sets of noise bursts was varied. Long and short sequences were studied to investigate the build-up effect for segregation based on spectral and AM-rate differences. Results showed the following: 1. Stream segregation ability increased with greater spectral separation. 2. Larger AM-rate separations were associated with stronger segregation abilities. 3. Spectral separation was found to elicit the build-up effect for the range of spectral differences assessed in the current study. 4. AM-rate separation interacted with spectral separation suggesting an additive effect of spectral separation and AM-rate separation on segregation build-up. The findings suggest that, when normal-hearing listeners direct their attention toward segregation, they are able to segregate auditory streams based on reduced spectral contrast cues that vary by the amount of spectral overlap. Further, regardless of the spectral separation they were able to use AM-rate difference as a secondary/weaker cue. Based on the spectral differences, listeners can segregate auditory streams better as the listening duration is prolonged—i.e. sparse spectral cues elicit build-up segregation; however, AM-rate differences only appear to elicit build-up when in combination with spectral difference cues.

  16. Methodological issues related to studies of lead mobilization during menopause

    Directory of Open Access Journals (Sweden)

    Berkowitz Gertrud S.

    1999-01-01

    Full Text Available While there has been a substantial decline in lead exposure in the United States during the past two decades, mobilization of existing lead stored in bone potentially represents an important endogenous source of exposure for menopausal women. It has been hypothesized that lead may be mobilized from skeletal stores during conditions of high bone turnover, such as during menopause. However, such mobilization has not been documented in prospective studies. This discussion is focussed on some of the methodological difficulties to be anticipated in longitudinal studies of lead mobilization specific to menopause and the issues that need to be taken into account when evaluating the results of such studies. To evaluate whether lead mobilization occurs during menopause, a prospective repeated measures design is needed using X-ray fluorescence analysis of lead in bone and serial measurements of blood lead. Potential confounders and effect modifiers also need to be taken into account in the statistical analysis.

    Currently preterm births are the leading causes of newborn deaths and newborn mortality in developed countries. Infants born prematurely remain vulnerable to many acute complications and long-term disabilities. There is a growing concern surrounding the moral and ethical implications of the complex and technological care being provided to extremely low birth weight infants in neonatal intensive care units in the developed nations. The purpose of this study was to describe the ethical and moral issues that neonatal intensive care nurses experience when caring for low birth weight preterm infants and their families. A phenomenological method design was used to describe the lived experiences of nurses with ethical and moral issues encountered in the neonatal intensive care unit. One-on-one, semi-structured interviews using open-ended questions were used to gather data from the participants. The setting for this study was a 97-bed neonatal intensive care. A total of 16 female nurses were interviewed. Approval to conduct the research study was obtained from the institutional review board of the hospital where the study was conducted. Formal signed consent was obtained from each participant. To ensure confidentiality, each participant was asked to choose a confederate name to be used in the interview and the transcriptions. The thematic analysis identified five recurring themes: (a) at the edge of viability, (b) infant pain and discomfort, (c) crucial decisions, (d) communicating with parents, and (e) letting go. Neonatal intensive care unit nurses indicated that they often had challenges to their own sense of morality as they struggled to protect the infant from pain and unnecessary discomfort, provide care to an infant and their family whom they thought was faced with a lifetime of challenges and poor health, accepting decisions made by parents, and feeling as if parents were not adequately informed about outcomes. © The Author(s) 2014.

    2012-05-01

    During the 2011 International Pigment Cell Conference (IPCC), the Vitiligo European Taskforce (VETF) convened a consensus conference on issues of global importance for vitiligo clinical research. As suggested by an international panel of experts, the conference focused on four topics: classification and nomenclature; definition of stable disease; definition of Koebner's phenomenon (KP); and 'autoimmune vitiligo'. These topics were discussed in seven working groups representing different geographical regions. A consensus emerged that segmental vitiligo be classified separately from all other forms of vitiligo and that the term 'vitiligo' be used as an umbrella term for all non-segmental forms of vitiligo, including 'mixed vitiligo' in which segmental and non-segmental vitiligo are combined and which is considered a subgroup of vitiligo. Further, the conference recommends that disease stability be best assessed based on the stability of individual lesions rather than the overall stability of the disease as the latter is difficult to define precisely and reliably. The conference also endorsed the classification of KP for vitiligo as proposed by the VETF (history based, clinical observation based, or experimentally induced). Lastly, the conference agreed that 'autoimmune vitiligo' should not be used as a separate classification as published evidence indicates that the pathophysiology of all forms of vitiligo likely involves autoimmune or inflammatory mechanisms. © 2012 John Wiley & Sons A/S.

    This minireview provides an overview of known and potential gender differences in physiological responses to spaceflight. The paper covers cardiovascular and exercise physiology, barophysiology and decompression sickness, renal stone risk, immunology, neurovestibular and sensorimotor function, nutrition, pharmacotherapeutics, and reproduction. Potential health and functional impacts associated with the various physiological changes during spaceflight are discussed, and areas needing additional research are highlighted. Historically, studies of physiological responses to microgravity have not been aimed at examining gender-specific differences in the astronaut population. Insufficient data exist in most of the discipline areas at this time to draw valid conclusions about gender-specific differences in astronauts, in part due to the small ratio of women to men. The only astronaut health issue for which a large enough data set exists to allow valid conclusions to be drawn about gender differences is orthostatic intolerance following shuttle missions, in which women have a significantly higher incidence of presyncope during stand tests than do men. The most common observation across disciplines is that individual differences in physiological responses within genders are usually as large as, or larger than, differences between genders. Individual characteristics usually outweigh gender differences per se.

  5. A Survey of Solver-Related Geometry and Meshing Issues

    Masters, James; Daniel, Derick; Gudenkauf, Jared; Hine, David; Sideroff, Chris

    2016-01-01

    There is a concern in the computational fluid dynamics community that mesh generation is a significant bottleneck in the CFD workflow. This is one of several papers that will help set the stage for a moderated panel discussion addressing this issue. Although certain general "rules of thumb" and a priori mesh metrics can be used to ensure that some base level of mesh quality is achieved, inadequate consideration is often given to the type of solver or particular flow regime on which the mesh will be utilized. This paper explores how an analyst may want to think differently about a mesh based on considerations such as if a flow is compressible vs. incompressible or hypersonic vs. subsonic or if the solver is node-centered vs. cell-centered. This paper is a high-level investigation intended to provide general insight into how considering the nature of the solver or flow when performing mesh generation has the potential to increase the accuracy and/or robustness of the solution and drive the mesh generation process to a state where it is no longer a hindrance to the analysis process.

  6. Legal issues related to adolescent pregnancy: current concepts.

    Science.gov (United States)

    Rhodes, A M

    1986-09-01

    Adolescent pregnancies have risen in recent years. Options open to the pregnant adolescent are: terminating the pregnancy; giving birth to the child out of wedlock; keeping the baby; giving the baby up for adoption; and marriage before or after the birth of the baby. Each of these options carries certain legal ramifications, since the adolescent patients have not reached the age of majority. The state or the parents usually assume the role of decision making on behalf of the adolescent or assist in the decision making process. Court rulings since the early seventies have legalized abortion and enlarged the rights of minors seeking termination of their pregnancies. Both parents and minors have rights under the certain state laws; parent have the right to notification, minors have the right to privacy. Keeping the child, out of wedlock, might result in legal battles over custody and/or establishing financial support from the father. Some adolescent mothers give up their children for adoption. There are 2 legal procedures that have to be accomplished before a child can be adopted: termination of the rights of the natural parents and adoption proceedings. If the parents marry after the birth of the child, the child is then considered legitimate and the father does not have to go through the process of adopting the child. Other issues requiring parental or individual consent include consent to treatment, contraception, or sterilization. In the case of forcible rape or incest, the physician is required to report incidents to law enforcement officials.

    A design study for a post-Large Hadron Collider accelerator named, Future Circular Collider (FCC), is being carried out by the International Scientific Community. A complete design report is expected to be ready by spring 2018. The FCC will accelerate two counter rotating beams of 50 TeV protons in a tunnel having a length (circumference) of 100 km. Each beam will be comprised of 10 600 proton bunches, with each bunch having an intensity of 1011 protons. The bunch length is of 0.5 ns, and two neighboring bunches are separated by 25 ns. Although there is an option for 5 ns bunch separation as well, in the present studies, we consider the former case only. The total energy stored in each FCC beam is about 8.5 GJ, which is equivalent to the kinetic energy of Airbus 380 (560 t) flying at a speed of 850 km/h. Machine protection is a very important issue while operating with such powerful beams. It is important to have an estimate of the damage caused to the equipment and accelerator components due to the accidental release of a partial or total beam at a given point. For this purpose, we carried out numerical simulations of full impact of one FCC beam on an extended solid copper target. These simulations have been done employing an energy deposition code, FLUKA, and a two-dimensional hydrodynamic code, BIG2, iteratively. This study shows that although the static range of a single FCC proton and its shower is about 1.5 m in solid copper, the entire beam will penetrate around 350 m into the target. This substantial increase in the range is due to the hydrodynamic tunneling of the beam. Our calculations also show that a large part of the target will be converted into high energy density matter including warm dense matter and strongly coupled plasmas.

    Recent interest has focused on the use of hormone therapy in prostate cancer for both the management of patients with non-metastatic disease and as a neoadjuvant or adjuvant to curative therapies. This has resulted in patients with fewer symptoms being treated for longer periods of time. Endocrine...... treatments for prostate cancer, such as castration, combined androgen blockade and non-steroidal antiandrogen monotherapy, have shown similar results in terms of time to progression and survival. The main difference between these treatments is their impact on patients' quality of life. Instruments...... for measuring health-related quality of life should assess both overall and disease-specific quality of life. Data from two large studies of bicalutamide monotherapy show that this non-steroidal antiandrogen is associated with significant health-related quality of life advantages in the treatment of patients...

    To review relevant literature regarding the effect of concussion on vestibular function, impairments, assessments and management strategies. REASONING: Dizziness and balance impairments are common following sport-related concussion. Recommendations regarding the management of sport-related concussion suggest including tests of balance within the multifactorial assessment paradigm for concussive injuries. The literature was searched for guidelines and original studies related to vestibular impairments following concussion, oculomotor and balance assessments and treatment or rehabilitation of vestibular impairments. The databases searched included Medline, CINAHL, Sport Discus and the Cochrane Database of Systematic Reviews through October 2013. Dizziness following concussion occurs in ∼67-77% of cases and has been implicated as a risk factor for a prolonged recovery. Balance impairments also occur after concussion and last 3-10 days post-injury. Assessments of balance can be done using both clinical and instrumented measures with success. Vestibular rehabilitation has been shown to improve outcomes in patients with vestibular impairments, with one study demonstrating success in decreasing symptoms and increasing function following concussion. Best practices suggest that the assessment of vestibular function through cranial nerve, oculomotor and balance assessments are an important aspect of concussion management. Future studies should evaluate the effectiveness of vestibular rehabilitation for improving patient outcomes.

    Malaysia had considered nuclear energy as an option for future electricity generation during the 9th Malaysia Development Plan. Since 2009, Malaysia had implemented a number of important preparatory steps towards this goal, including the establishment of Nuclear Power Corporation of Malaysia (MNPC) as first Nuclear Energy Programme Implementing Organization (NEPIO) in Malaysia. In light of the establishment of MNPC, the National Nuclear Policy was formulated in 2010 and a new comprehensive nuclear law to replace the existing Atomic Energy Licensing Act (Act 304) is currently in the pipeline. Internationally, public acceptance is generally used to gauge the acceptance of nuclear energy by the public whenever a government decides to engage in nuclear energy. A public survey was conducted in between 14 March 2016 to 10 May 2016 focusing on the Malaysian public acceptance and perception towards the implementation of nuclear energy in Malaysia. The methodology of this research was aim on finding an overview of the general knowledge, public-relation recommendation, perception and acceptance of Malaysian towards the nuclear power development program. The combination of information gathered from this study can be interpreted as an indication of the complexity surrounding the development of nuclear energy and its relationship with the unique background of Malaysian demography. This paper will focus mainly on energy-related section in the survey in comparison with nuclear energy.

  15. Global hydrobelts: improved reporting scale for water-related issues?

    Science.gov (United States)

    Meybeck, M.; Kummu, M.; Dürr, H. H.

    2012-08-01

    Questions related to water such as its availability, water needs or stress, or management, are mapped at various resolutions at the global scale. They are reported at many scales, mostly along political or continental boundaries. As such, they ignore the fundamental heterogeneity of the hydroclimate and the natural boundaries of the river basins. Here, we describe the continental landmasses according to eight global-scale hydrobelts strictly limited by river basins, defined at a 30' (0.5°) resolution. The belts were defined and delineated, based primarily on the annual average temperature (T) and runoff (q), to maximise interbelt differences and minimise intrabelt variability. The belts were further divided into 29 hydroregions based on continental limits. This new global puzzle defines homogeneous and near-contiguous entities with similar hydrological and thermal regimes, glacial and postglacial basin histories, endorheism distribution and sensitivity to climate variations. The Mid-Latitude, Dry and Subtropical belts have northern and southern analogues and a general symmetry can be observed for T and q between them. The Boreal and Equatorial belts are unique. The hydroregions (median size 4.7 Mkm2) contrast strongly, with the average q ranging between 6 and 1393 mm yr-1 and the average T between -9.7 and +26.3 °C. Unlike the hydroclimate, the population density between the North and South belts and between the continents varies greatly, resulting in pronounced differences between the belts with analogues in both hemispheres. The population density ranges from 0.7 to 0.8 p km-2 for the North American Boreal and some Australian hydroregions to 280 p km-2 for the Asian part of the Northern Mid-Latitude belt. The combination of population densities and hydroclimate features results in very specific expressions of water-related characteristics in each of the 29 hydroregions. Our initial tests suggest that hydrobelt and hydroregion divisions are often more

    As an important component of water resources, groundwater plays a crucial role in water utilization in China and an irreplaceable role in supporting economic and social development, especially in the northern arid and semi-arid plains and basin areas, which are densely populated and relatively short of surface-water resources. This paper comprehensively reviews and discusses the regional hydrogeological conditions, the temporal and spatial distribution of groundwater, the groundwater quality, and the actuality of groundwater exploitation and utilization in China. Meanwhile, aiming at the environmental problems induced by overexploitation to meet the sharply increasing water demand, this paper puts forward the major tasks for the next few years in terms of groundwater exploitation control, conservation and management.

  17. Main safety issues related to IPSN severe accident research

    LeComte, C.

    1991-01-01

    The work performed at IPSN concerning accident studies on nuclear installations is focused on the characterization of accidental sequences with three major aims: prevention, mitigation, and organization of counter-measures. As criteria to optimize all efforts made to improve nuclear safety, the radioactive dispersal in the environment must be quantified as function of internal and external radioactive products transfers. During the short-term phase of the accident, potential radioactive releases can be evaluated by the realistic code system ESCADRE. This system is validated by numerous analytical studies related to containment and fission product behavior. It will be further qualified by the results of the global experiments performed in the PHEBUS FP facility at IPSN

  19. Some issues related to evidence-based implantology

    Directory of Open Access Journals (Sweden)

    Gunnar E Carlsson

    2016-01-01

    Full Text Available This article reviews relevant dental literature to answer some frequent questions related to evidence-based implantology. There are hundreds of implant systems on the market, but the majority lack clinical documentation. Recommended number of implants for full-arch fixed prostheses is four or five in the mandible but at least six in the maxilla. Less expensive implant-retained overdentures make implant treatment available to a greater portion of edentulous subjects. Mandibular overdentures on two implants, and even one implant, have shown excellent long-term outcomes. In the maxilla, less than four implants are not recommended for good results. Single implant restorations have good prognosis, but placement of the implant should be postponed until adulthood. Osseointegrated implants have revolutionized clinical dentistry. However, in a global perspective, implants make up only a small part of all prosthodontic treatment. Knowledge and skill in conventional prosthodontics must be maintained as it will remain the most common part of the specialty.

    The body of research that reports the relevance of sleep in high-performance sports is growing steadily. While the identification of sleep cycles and diagnosis of sleep disorders is limited to lab-based assessment via polysomnography, the development of activity-based devices estimating sleep patterns provides greater insight into the sleep behaviour of athletes in ecological settings. Overall, small sleep quantity and/or poor quality appears to exist in many athletic populations, though this may be related to training and competition context. Typical sleep-affecting factors are the scheduling of training sessions and competitions as well as impaired sleep-onset as a result of increased arousal prior to competition or due to the use of electronic devices before bedtime. Further challenges are travel demands which may be accompanied by jet-lag symptoms and disruption of sleep habits. Promotion of sleep may be approached via behavioural strategies, such as sleep hygiene, extending night-time sleep or daytime napping. Pharmacological interventions should be limited to clinically-induced treatments as evidence among healthy and athletic populations is lacking. To optimise and manage sleep in athletes, it is recommended to implement routine sleep monitoring on an individual basis.

  1. Breaking bad news: issues relating to nursing practice.

    Science.gov (United States)

    Warnock, Clare

    2014-07-15

    The breaking of bad news was traditionally regarded to be the time when a doctor and nurse sat down with a patient and family members to provide information about, for example, a life-limiting diagnosis or a poor prognosis. However, breaking bad news is now generally accepted as a process, not a one-off event, and is considered to refer to any bad, sad or difficult information that alters patients' perceptions of their present and future. Nurses have an important role in the process of providing information and helping patients prepare for, receive, understand and cope with the bad news they have been given. This article aims to help nurses understand the process of breaking bad news and discuss the challenges and difficulties that nurses can face when they are involved with patients who have been given bad news. It also provides guidance with regard to preparing for breaking bad news, giving difficult information, responding to possible reactions, and supporting patients and their relatives after they have received bad news.

  3. Piecewise spectrally band-pass for compressive coded aperture spectral imaging

    International Nuclear Information System (INIS)

    Qian Lu-Lu; Lü Qun-Bo; Huang Min; Xiang Li-Bin

    2015-01-01

    Coded aperture snapshot spectral imaging (CASSI) has been discussed in recent years. It has the remarkable advantages of high optical throughput, snapshot imaging, etc. The entire spatial-spectral data-cube can be reconstructed with just a single two-dimensional (2D) compressive sensing measurement. On the other hand, for less spectrally sparse scenes, the insufficiency of sparse sampling and aliasing in spatial-spectral images reduce the accuracy of reconstructed three-dimensional (3D) spectral cube. To solve this problem, this paper extends the improved CASSI. A band-pass filter array is mounted on the coded mask, and then the first image plane is divided into some continuous spectral sub-band areas. The entire 3D spectral cube could be captured by the relative movement between the object and the instrument. The principle analysis and imaging simulation are presented. Compared with peak signal-to-noise ratio (PSNR) and the information entropy of the reconstructed images at different numbers of spectral sub-band areas, the reconstructed 3D spectral cube reveals an observable improvement in the reconstruction fidelity, with an increase in the number of the sub-bands and a simultaneous decrease in the number of spectral channels of each sub-band.

    2015-12-01

    Full Text Available In this paper, we introduce the design and the achievement of a Bandpass filter structure based on the use of rectangular slot cell. The originality of this work is to achieve a coplanar filter easy to integrate with microwave planar circuits and having a wide frequency bandwidth. The proposed bandpass filter is a low cost and compact planar filter structure. The final circuit is simulated by using two electromagnetic solvers, ADS and HFSS. The validation into simulation is based on using optimization methods integrated into the both solvers. Simulations have taken into account a high meshing density to cover the whole circuit. The fabricated bandpass filter has an area of 35X31mm2 and having a good insertion loss around -0.75dB in the bandwidth. The comparison between simulation and measurement results presents a good agreement.

    Xiao, Jian-Kang; Zhu, Wen-Jun; Zhao, Wei

    2014-05-01

    A novel Π-shaped resonator is proposed, and compact dual-band and tri-band bandpass filters that meet IEEE 802.11 application requirements by using the new resonator are designed. The dual-band bandpass filter centres at 2.45 and 5.6 GHz with a simulated passband insertion loss of no more than 0.8 dB, and the tri-band bandpass filter which is got by two-path coupling achieves simulated passband insertion loss of no more than 1.1 dB. The new designs are demonstrated by experiment. The new filters have advantages of simple and compact structures, low passband insertion losses, good frequency selectivity and miniature circuit sizes. All these have prospect to be applied in future wireless communication systems.

  6. High Selectivity Dual-Band Bandpass Filter with Tunable Lower Passband

    Directory of Open Access Journals (Sweden)

    Wei-Qiang Pan

    2015-01-01

    Full Text Available This paper presents a novel method to design dual-band bandpass filters with tunable lower passband and fixed upper passband. It utilizes a trimode resonator with three controllable resonant modes. Discriminating coupling is used to suppress the unwanted mode to avoid the interference. Varactors are utilized to realize tunable responses. The bandwidth of the two bands can be controlled individually. Transmission zeros are generated near the passband edges, resulting in high selectivity. For demonstration, a tunable bandpass filter is implemented. Good agreement between the prediction and measurement validates the proposed method.

  7. A Miniaturize Bandpass Filter with Harmonic Suppression Using Meandered Quarter-Wavelength Resonators

    Directory of Open Access Journals (Sweden)

    Yun-Long Lu

    2014-01-01

    Full Text Available A miniaturized bandpass filter with harmonics suppression is presented. The proposed filter consists of two quarter-wavelength microstrip resonators, which are meandered for circuit size reduction. An interdigital capacitor, loading at zero-voltage point, is employed to provide the desired coupling between the resonators at operating frequency, whereas the coupling coefficient at the third harmonic is realized to be zero. Besides, the second and fourth harmonics are suppressed since λ/4 resonators are adopted. Benefiting from these properties, a miniaturized bandpass filter with the second, third, and fourth harmonics suppression was designed and implemented. The final measured and simulated results show good consistence with the theoretical counterparts.

    2016-01-01

    Full Text Available A microwave miniaturized bandpass filter using (Mg0.95Ca0.05TiO3 (abbreviated as 95MCT hereafter ceramic substrate is investigated in the present paper. The paper studies the sintering and microwave dielectric properties of Al2O3, La2O3 and SiO2 co-doped 95MCT. The XRD pattern shows that a secondary phase MgTi2O5 is easily segregated in 95MCT ceramic, however, through co-doping it can be effectively suppressed, and the microwave dielectric properties, especially, the Qf value can be significantly improved. Through optimizing the co-doping ratio of Al2O3, La2O3 and SiO2, the sintering temperature of 95MCT ceramic can be lowered by 80°C, and the microwave dielectric properties can reach Qf=61856GHz and εr=19.84, which indicates the modified 95MCT ceramic have a great potential application in microwave communication devices. Based on this, we also designed a miniaturized microwave bandpass filter (BPF on modified 95MCT substrate. Through a full wave electromagnetic structure simulation, the results show that the center frequency of the BPF is 2.45GHz and the relative bandwidth is 4.09% with the insertion loss of less than 0.2dB in the whole bandpass.

    Directory of Open Access Journals (Sweden)

    C. Y. Fang

    2015-08-01

    Full Text Available In order to effectively obtain a miniaturized structure and good filtering properties, we propose a novel 2nd-order bandpass metamaterial frequency selective surface (MFSS filter which contains two capacitive layers and one inductive layer, where there are multi-loop metallic patches as shunt capacitor C and planar wire grids as series inductor L respectively. Unlike the traditional operation way—the tuned elements used in resonant surface approximately equal to one wavelength in circumference and the structure thickness with a spacing of a quarter wavelength apart, by changing the value of L and C and matching multilayer dielectric to adjust the LC coupling resonance and the resonance impedance respectively, the proposed MFSS filter can achieves a miniatured structure with ideal bandpass properties. Measurement results of the fabricated prototype of the bandpass filter (BPF indicate that the dimension of the tuned element on resonant surface is approximately 0.025 wavelength, i.e., 0.025λ. At the same time, the filter has the stable center frequency of f0 = 1.53GHz and the transmittance of T ⩾ 96.3% and high Q-value for the TE/TM wave polarization at various incidence angles. The novel 2nd-order bandpass MFSS filter with miniaturized structure not only can decrease structure dimension, but also has a wide range of applications to microwave and infrared band.

  19. Optimization of band-pass filtering parameters of a Raman lidar detecting atmospheric water vapor

    International Nuclear Information System (INIS)

    Cao, Kai-Fa; Hu, Shun-Xing; Wang, Ying-jian

    2012-01-01

    It is very important for daytime Raman lidar measurement of water vapor to determine the parameters of a band-pass filter, which are pertinent to the lidar signal to noise ratio (SNR). The simulated annealing (SA) algorithm method has an advantage in finding the extremum of a certain cost function. In this paper, the Raman spectrum of water vapor is simulated and then a first realization of a simulated annealing algorithm in the optimization of a band-pass filter of a Raman lidar system designed to detect daytime water vapor is presented. The simulated results indicate that the narrow band-pass filter has higher SNR than the wide filter does but there would be an increase in the temperature sensitivity of a narrowband Raman water vapor lidar in the upper troposphere. The numerical simulation indicates that the magnitude of the temperature dependent effect can reach 3.5% or more for narrow band-pass Raman water vapor measurements so it is necessary to consider a new water vapor Raman lidar equation that permits the temperature sensitivity of these equations to be confined to a single term.

  20. Noise-Coupled Image Rejection Architecture of Complex Bandpass ΔΣAD Modulator

    Science.gov (United States)

    San, Hao; Kobayashi, Haruo

    This paper proposes a new realization technique of image rejection function by noise-coupling architecture, which is used for a complex bandpass ΔΣAD modulator. The complex bandpass ΔΣAD modulator processes just input I and Q signals, not image signals, and the AD conversion can be realized with low power dissipation. It realizes an asymmetric noise-shaped spectra, which is desirable for such low-IF receiver applications. However, the performance of the complex bandpass ΔΣAD modulator suffers from the mismatch between internal analog I and Q paths. I/Q path mismatch causes an image signal, and the quantization noise of the mirror image band aliases into the desired signal band, which degrades the SQNDR (Signal to Quantization Noise and Distortion Ratio) of the modulator. In our proposed modulator architecture, an extra notch for image rejection is realized by noise-coupled topology. We just add some passive capacitors and switches to the modulator; the additional integrator circuit composed of an operational amplifier in the conventional image rejection realization is not necessary. Therefore, the performance of the complex modulator can be effectively raised without additional power dissipation. We have performed simulation with MATLAB to confirm the validity of the proposed architecture. The simulation results show that the proposed architecture can achieve the realization of image-rejection effectively, and improve the SQNDR of the complex bandpass ΔΣAD modulator.

  2. Selected legal and institutional issues related to Ocean Thermal Energy Conversion (OTEC) development

    Energy Technology Data Exchange (ETDEWEB)

    Nanda, V. P.

    1979-06-01

    Ocean Thermal Energy Conversion (OTEC), an attractive alternative to traditional energy sources, is still in the early stages of development. To facilitate OTEC commercialization, it is essential that a legal and institutional framework be designed now so as to resolve uncertainties related to OTEC development, primarily involving jurisdictional, regulatory, and environmental issues. The jurisdictional issues raised by OTEC use are dependent upon the site of an OTEC facility and its configuration; i.e., whether the plant is a semipermanent fixture located offshore or a migrating plant ship that provides a source of energy for industry at sea. These issues primarily involve the division of authority between the Federal Government and the individual coastal states. The regulatory issues raised are largely speculative: they involve the adaptation of existing mechanisms to OTEC operation. Finally, the environmental issues raised center around compliance with the National Environmental Policy Act (NEPA) as well as international agreements. 288 references.

    This document describes the activities and results of the Multiple System Responses (MSR) program conducted by the Nuclear Operations Analysis Center (NOAC) at Oak Ridge National Laboratory (ORNL). The objective of the MSR program was to gather and review documentation for several unresolved safety issues and related programs of interest, and from that documentation, describe any additional potential safety concerns. The MSR program provides information that will aid the NRC staff in making an assessment of the relative safety significance of the concerns through the established prioritization process. Judgments were not made regarding the validity of the concerns expressed by others. Rather, the concerns were documented and potential safety issues were developed and defined as specifically as possible. Twenty-one potential safety issues were developed from the documented concerns. Additional information was gathered to support the NRC efforts in reviewing these issues for prioritization. 73 refs., 2 tabs

  4. Popper and Dingle on special relativity and the issue of symmetry

    Science.gov (United States)

    Dotson, Allen Clark

    2012-02-01

    Karl Popper and Herbert Dingle engaged in a fascinating debate concerning the kind of theory the special theory of relativity is. One of the issues was whether applications of the theory could be made consistent with the principle of relativity, a cornerstone of the theory itself. The principle of relativity seems to imply some sort of symmetry in results obtained for similar experiments as observed in two different inertial reference frames. Peter Hayes has recently dealt with the Dingle-Popper debate on this matter, as well as other issues. The present paper seeks to clarify what kind of symmetry is appropriate in a situation discussed by Popper, Dingle, and Hayes.

    The report points out topical legal issues relating to nuclear waste disposal, yet leaves no doubt that the technical-scientific concept for nuclear waste disposal incorporated into the nuclear energy law in 1976 was a success. Nonetheless it is desirable that there should be persistent efforts especially on the part of parliament when issuing legislation or statutory orders to reach greater clearness and thus predictability in areas where technology has been proven by many years of practice.

  12. Multiple plasmonically induced transparency for chip-scale bandpass filters in metallic nanowaveguides

    Science.gov (United States)

    Lu, Hua; Yue, Zengqi; Zhao, Jianlin

    2018-05-01

    We propose and investigate a new kind of bandpass filters based on the plasmonically induced transparency (PIT) effect in a special metal-insulator-metal (MIM) waveguide system. The finite element method (FEM) simulations illustrate that the obvious PIT response can be generated in the metallic nanostructure with the stub and coupled cavities. The lineshape and position of the PIT peak are particularly dependent on the lengths of the stub and coupled cavities, the waveguide width, as well as the coupling distance between the stub and coupled cavities. The numerical simulations are in accordance with the results obtained by the temporal coupled-mode theory. The multi-peak PIT effect can be achieved by integrating multiple coupled cavities into the plasmonic waveguide. This PIT response contributes to the flexible realization of chip-scale multi-channel bandpass filters, which could find crucial applications in highly integrated optical circuits for signal processing.

    International Nuclear Information System (INIS)

    Lu Hua; Liu Xueming; Wang Guoxi; Mao Dong

    2012-01-01

    We have proposed a novel type of bandpass plasmonic filter consisting of metal–insulator–metal bus waveguides coupled with a series of side-coupled cavities and stub waveguides. The theoretical modeling demonstrates that our waveguide-resonator system performs a plasmonic analogue of electromagnetically induced transparency (EIT) in atomic systems, as is confirmed by numerical experiments. The plasmonic EIT-like response enables the realization of nanoscale bandpass filters with multiple channels. Additionally, the operating wavelengths and bandwidths of our filters can be efficiently tuned by adjusting the geometric parameters such as the lengths of stub waveguides and the coupling distances between the cavities and stub waveguides. The ultracompact configurations contribute to the achievement of wavelength division multiplexing systems for optical computing and communications in highly integrated optical circuits. (paper)

    Liu, Haiwen; Wang, Shuxin; Tan, Mingtao; Zhang, Qijun

    2010-02-01

    Compact left-handed coplanar waveguide (CPW) bandpass filter loaded split ring resonator (SRR) is presented in this paper. The proposed filter exhibits a quasi-elliptic function response and its circuit size occupies only 12 × 11.8 mm2 (≈0.21 λg × 0.20 λg). Also, a simple circuit model is given and the parametric study of this filter is discussed. Then, with the aid of NeuroModeler software, a five-layer feed-forward perceptron neural networks model is built up to optimize the proposed filter design fast and accurately. Finally, this newly left-handed CPW bandpass filter was fabricated and measured. A good agreement between simulations and measurement verifies the proposed left-handed filter and the validity of design methodology.

  15. A Compact Band-Pass Filter with High Selectivity and Second Harmonic Suppression.

    Science.gov (United States)

    Hadarig, Ramona Cosmina; de Cos Gomez, Maria Elena; Las-Heras, Fernando

    2013-12-03

    The design of a novel band-pass filter with narrow-band features based on an electromagnetic resonator at 6.4 GHz is presented. A prototype is manufactured and characterized in terms of transmission and reflection coefficient. The selective passband and suppression of the second harmonic make the filter suitable to be used in a C band frequency range for radar systems and satellite/terrestrial applications. To avoid substantial interference for this kind of applications, passive components with narrow band features and small dimensions are required. Between 3.6 GHz and 4.2 GHz the band-pass filter with harmonic suppression should have an attenuation of at least 35 dB, whereas for a passband, less than 10% is sufficient.

    2015-06-01

    Full Text Available Abstract: The two major political coalitions in Malaysia are Barisan Nasional  (BN and Pakatan Rakyat (PR, which are dominated by the Malay-Muslim majority. During the 13th national election, to gain public votes, the government used mainstream newspapers to frame Islam-related issues. This research focuses on the characterisation and information reported about Islam and Muslims during the 13th General Election. Using content analysis, we examine the coverage of such issues by the mainstream newspapers: Berita Harian, Utusan Malaysia, New Straits Times, and The Star. This analysis aims to provide a holistic review of the scope of the coverage during the period with a focus on how the Malaysian government framed Islam-related issues through the print media in order to gain the Malay votes. A total of 178 news articles were analysed, from which we found that 15 dominant issues were reported in the newspapers during that period. Among the most frequently reported Islam-related issues were hudud (prescribed punishments, Islamic state, and kalimah Allah (the word “Allah”, which were predominantly covered by the Malay newspapers. In addition, the data indicated that most of the news were inclined towards supporting the ruling coalition, i.e., Barisan Nasional.

  18. Love versus abuse: crossgenerational sexual relations of minors: a gay rights issue?

    Science.gov (United States)

    Graupner, H

    1999-01-01

    The question discussed is how far crossgenerational sexual relations with or by minors could be considered to be a gay rights issue. The author discusses the issue from the perspective of general principles found in the case-law of the European Court on Human Rights. These principles suggest that the basic right to privacy should be interpreted as providing comprehensive protection of the right of children and adolescents to sexual self-determination, namely both the right to effective protection from (unwanted) sex and abuse on the one hand and the right to (wanted) sex on the other. The analysis is based upon the findings of natural and social science as well as an extensive international survey of national legal provisions and it leads to the conclusion that consensual sexual relations of and with adolescents over 14 (out of relations of authority) should be qualified a gay rights issue; likewise (as the exception to the rule) the possibility of filtering out cases from prosecution where a contact/relation is proven (beyond reasonable doubt) as consensual and harmless even though the minor involved is under 14. The legalization of (objectively consensual) sexual relations with persons under 14 as such, however, should not be considered to be a gay rights issue.

    The Cycle 5 design baseline for the Wide-Field Infrared Survey Telescope Astrophysics Focused Telescope Assets (WFIRST/AFTA) instrument includes a single wide-field channel (WFC) instrument for both imaging and slit-less spectroscopy. The only routinely moving part during scientific observations for this wide-field channel is the element wheel (EW) assembly. This filter-wheel assembly will have 8 positions that will be populated with 6 bandpass filters, a blank position, and a Grism that will consist of a three-element assembly to disperse the full field with an undeviated central wavelength for galaxy redshift surveys. All filter elements in the EW assembly will be made out of fused silica substrates (110 mm diameter) that will have the appropriate bandpass coatings according to the filter designations (Z087, Y106, J129, H158, F184, W149 and Grism). This paper presents and discusses the performance (including spectral transmission and reflected/transmitted wavefront error measurements) of a subset of bandpass filter coating prototypes that are based on the WFC instrument filter compliment. The bandpass coating prototypes that are tested in this effort correspond to the Z087, W149, and Grism filter elements. These filter coatings have been procured from three different vendors to assess the most challenging aspects in terms of the in-band throughput, out of band rejection (including the cut-on and cutoff slopes), and the impact the wavefront error distortions of these filter coatings will have on the imaging performance of the wide-field channel in the WFIRST/AFTA observatory.

    We propose a simple OFDM receiver allowing for the use of standard WDM receivers to receive spectrally advanced OFDM signals. We propose to spectrally magnify the optical-OFDM super-channels using a spectral telescope consisting of two time-lenses, which enables reduced inter-carrier-interference in subcarrier detection by simple band-pass filtering. A demonstration on an emulated 100 Gbit/s DPSK optical-OFDM channel shows improved sensitivities after 4-times spectral magnification.

    Men and women with rheumatic diseases report a significantly negative impact on multiple areas of life, including sexuality. Research indicates that patients want to discuss sexual issues with health professionals (HPs) in rheumatology care but these issues are rarely addressed in consultations. The objective of the present study was to explore patients' experiences of communication with HPs about disease-related sexual issues, their perceptions of the relevance of these issues in rheumatology care and their preferences for how these topics should be handled. A qualitative design was used and 18 semi-structured interviews were performed, including eight women and ten men with inflammatory rheumatic joint diseases, aged 29-62 years. The interviews were recorded and transcribed verbatim. Data were analysed thematically. Four main themes were derived from the interviews: (i) relevance of sexual issues; (ii) vital conditions for communication; (iii) individual preferences in mode and timing of information and communication; and (iv) benefits of information and communication. The participants expressed that, although sexual issues are relevant, necessary conditions for good communication are largely lacking. HPs' knowledge, experience and personal skills, as well as having sufficient time were essential. HPs lack of initiating sexual topics contributed to uncertainty about whether their sexual challenges were disease related and whether it was a legitimate topic to discuss in rheumatology care. Patients wanted HPs to possess knowledge about possible disease-related challenges in sexual life and intimate relationships, and to facilitate communication about these aspects. There is a need to develop practice guidelines to enable HPs to integrate sexual issues as an aspect of healthcare delivery in a patient-friendly manner. Copyright © 2016 John Wiley & Sons, Ltd.

    One of the most promising materials for low-cost thin film photovoltaic cells is copper indium selenide (CuInSe{sub 2} or CIS). As with any new material, successful commercialization of CIS photovoltaic (PV) technology will require attention to environmental issues related to the sources of raw materials, their usage, and the disposal and/or recycling of products at the end of their useful life. This paper focuses on three specific environmental issues related to CIS technology: (i) Economics of the use and re-use of materials; (ii) regulations on environmental disposal and waste handling, and (iii) logistics and economics of recycling and disposing of products by industries faced with comparable environmental issues.

    Brain-Computer Interface (BCI) research and (future) applications raise important ethical issues that need to be addressed to promote societal acceptance and adequate policies. Here we report on a survey we conducted among 145 BCI researchers at the 4 th International BCI conference, which took place in May-June 2010 in Asilomar, California. We assessed respondents' opinions about a number of topics. First, we investigated preferences for terminology and definitions relating to BCIs. Second, we assessed respondents' expectations on the marketability of different BCI applications (BCIs for healthy people, BCIs for assistive technology, BCIs-controlled neuroprostheses and BCIs as therapy tools). Third, we investigated opinions about ethical issues related to BCI research for the development of assistive technology: informed consent process with locked-in patients, risk-benefit analyses, team responsibility, consequences of BCI on patients' and families' lives, liability and personal identity and interaction with the media. Finally, we asked respondents which issues are urgent in BCI research.

  5. On the optimal sampling of bandpass measurement signals through data acquisition systems

    International Nuclear Information System (INIS)

    Angrisani, L; Vadursi, M

    2008-01-01

    Data acquisition systems (DAS) play a fundamental role in a lot of modern measurement solutions. One of the parameters characterizing a DAS is its maximum sample rate, which imposes constraints on the signals that can be alias-free digitized. Bandpass sampling theory singles out separated ranges of admissible sample rates, which can be significantly lower than carrier frequency. But, how to choose the most convenient sample rate according to the purpose at hand? The paper proposes a method for the automatic selection of the optimal sample rate in measurement applications involving bandpass signals; the effects of sample clock instability and limited resolution are also taken into account. The method allows the user to choose the location of spectral replicas of the sampled signal in terms of normalized frequency, and the minimum guard band between replicas, thus introducing a feature that no DAS currently available on the market seems to offer. A number of experimental tests on bandpass digitally modulated signals are carried out to assess the concurrence of the obtained central frequency with the expected one

    2018-06-01

    Inverse photoemission is the most versatile experimental tool to study the unoccupied electronic structure at surfaces of solids. Typically, the experiments are performed in the isochromat mode with bandpass photon detectors. For gas-filled counters, the bandpass behavior is realized by the combination of the photoionization threshold of the counting gas as the high-pass filter and the ultraviolet transmission cutoff of an alkaline earth fluoride entrance window as the low-pass filter. The transmission characteristics of the entrance window determine the optical bandpass. The performance of the counter depends on the composition of the detection gas and the fill-gas pressure, the readout electronics and the counter geometry. For the well-known combination of acetone and CaF2, the detector can be operated in proportional and Geiger–Müller modes. In this work, we review aspects concerning the working principles, the counter construction and the read-out electronics. We identify optimum working parameters and provide a step-by-step recipe how to build, install and operate the device.

    Data on awareness of adolescent's on the legal and social issues/acts related to reproductive health, especially in rural areas, are scarce. The aim of the present cross-sectional study is to assess the awareness level of legal and social issues related to reproductive health and its association with the various individual and family/household level characteristics. 650 adolescent girls in the age group of 15-19 years were interviewed with the help of pretested and semistructured questionnaire and focus group discussions were also conducted for qualitative findings in Chiraigaon block of district Varanasi. It was observed that 42.9% of the respondents were aware of legal age of marriage, 14.9% knew about the right age of childbearing. Dowry prohibition act and domestic violence act were known to 46% and 27% respondents, respectively, and only 2.6% were aware of medical termination of pregnancy act. Logistic regression analysis shows the significant effect of education on awareness of legal age of marriage, right age of childbearing, domestic violence, and dowry prohibition acts, which is also supported by qualitative findings. All the important legal issues/acts should be included in high school curriculum and female teachers should be involved in training program for adolescents. Role of mass media in creating awareness about these issues in their routine programs should be ascertained. Accredited Social Health Activist and Anganwadi workers should be aware of and include these issues/acts in adolescent meetings.

  16. Problems in complying with regulations related to low activity materials: Nuclear fuel cycle issues

    International Nuclear Information System (INIS)

    Coates, R.

    1997-01-01

    The range of issues relating to exemption and clearance within the nuclear fuel cycle is reviewed. It is concluded that current regulatory systems and the underpinning technical criteria are potentially inflexible and over-conservative, resulting in an imbalance in the use of society's resources. Proposals are developed for establishing practical requirements which would ensure that resource allocation is commensurate with the magnitude of the risks and in broad proportion to the other risks affecting society. Such an approach would be consistent with the concept of sustainability and could support wider public acceptance of these issues. Within this approach the practical distinction between exemption and clearance is challenged. (author)

    The purpose of this report is to document current scientific knowledge of the climate-related conditions and processes relevant to the long-term safety of a KBS-3 repository to a level required for an adequate treatment in the safety assessment SR-Can. The report also includes a concise background description of the climate system. The report includes three main chapters: A description of the climate system (Chapter 2); Identification and discussion of climate-related issues (Chapter 3); and, A description of the evolution of climate-related conditions for the safety assessment (Chapter 4). Chapter 2 includes an overview of present knowledge of the Earth climate system and the climate conditions that can be expected to occur in Sweden on a 100,000 year time perspective. Based on this, climate-related issues relevant for the long-term safety of a KBS-3 repository are identified. These are documented in Chapter 3 'Climate-related issues' to a level required for an adequate treatment in the safety assessment. Finally, in Chapter 4, 'Evolution of climate-related conditions for the safety assessment' an evolution for a 120,000 year period is presented, including discussions of identified climate-related issues of importance for repository safety. The documentation is from a scientific point of view not exhaustive, since such a treatment is neither necessary for the purposes of the safety assessment nor possible within the scope of a safety assessment. As further described in the SR-Can Main Report and in the Features Events and Processes report, the content of the present report has been audited by comparison with FEP databases compiled in other assessment projects. This report follows as far as possible the template for documentation of processes regarded as internal to the repository system. However, the term processes is not used in this report, instead the term issue has been used. Each issue includes a set of processes together resulting in the behaviour of a

The documentation is from a scientific point of view not exhaustive, since such a treatment is neither necessary for the purposes of the safety assessment nor possible within the scope of a safety assessment. As further described in the SR-Can Main Report and in the Features Events and Processes report, the content of the present report has been audited by comparison with FEP databases compiled in other assessment projects. This report follows as far as possible the template for documentation of processes regarded as internal to the repository system. However, the term processes is not used in this report, instead the term issue has been used. Each issue includes a set of processes together resulting in the

    Identification and analysis of privacy and security related issues that occur when health information is exchanged between health care organizations. Based on a generic scenario questions were formulated to reveal the occurring issues. Possible answers were verified in literature. Ensuring secure health information exchange across organizations requires a standardization of security measures that goes beyond organizational boundaries, such as global definitions of professional roles, global standards for patient consent and semantic interoperable audit logs. As to be able to fully address the privacy and security issues in interoperable EHRs and the long-life virtual EHR it is necessary to realize a paradigm shift from storing all incoming information in a local system to retrieving information from external systems whenever that information is deemed necessary for the care of the patient.

    Islamic religious leaders (IRLs) have the potential to influence health education, health promotion, and positive health outcomes among their own communities. This study aims to examine the role and effectiveness of Arab Muslim religious leaders, in Israel, as social agents for change on health-related issues, focusing on reduction in infant mortality, prematurity, and congenital malformations attributed to consanguineous marriage. A self-administrated questionnaire was distributed to 127 IRLs, in 2012, to gain insights into practice, attitudes, and perceptions of IRLs toward their role as social agents for change on health-related issues. The results indicate that two-thirds (58%) of the surveyed IRLs have provided frequent advice on issues related to preventing infant mortality, congenital malformation, and prematurity over the past two years. Most IRLs indicated that they have keen interest in their communities' health matters (97%) and regard dealing with them as part of their job (85%). The study identified three enabling factors that had significant influence on the IRLs' attitude. These influences are: awareness and knowledge of the health issues, the perception that these issues and their impact on the community are part of their responsibility, and the empowerment they felt through the participation in the Ministry of Health (Northern Region Health Office) educational seminar series, in the year 2000. The main conclusion from this study indicates that IRLs are effective social agents for change and that the educational interventions can be a useful and effective strategy to encourage IRLs to cooperate with health providers and promote public health among their own communities.

    Identifying the gaps in public knowledge of women's health related issues has always been difficult. With the increasing number of Internet users in the United States, we sought to use the Internet as a tool to help us identify such gaps and to estimate women's most prevalent health concerns by examining commonly searched health-related keywords in Google search engine. We collected a large pool of possible search keywords from two independent practicing obstetrician/gynecologists and classified them into five main categories (obstetrics, gynecology, infertility, urogynecology/menopause and oncology), and measured the monthly average search volume within the United States for each keyword with all its possible combinations using Google AdWords tool. We found that pregnancy related keywords were less frequently searched in general compared to other categories with an average of 145,400 hits per month for the top twenty keywords. Among the most common pregnancy-related keywords was "pregnancy and sex' while pregnancy-related diseases were uncommonly searched. HPV alone was searched 305,400 times per month. Of the cancers affecting women, breast cancer was the most commonly searched with an average of 247,190 times per month, followed by cervical cancer then ovarian cancer. The commonly searched keywords are often issues that are not discussed in our daily practice as well as in public health messages. The search volume is relatively related to disease prevalence with the exception of ovarian cancer which could signify a public fear.

  2. Leveraging People-Related Maturity Issues for Achieving Higher Maturity and Capability Levels

    Science.gov (United States)

    Buglione, Luigi

    During the past 20 years Maturity Models (MM) become a buzzword in the ICT world. Since the initial Crosby's idea in 1979, plenty of models have been created in the Software & Systems Engineering domains, addressing various perspectives. By analyzing the content of the Process Reference Models (PRM) in many of them, it can be noticed that people-related issues have little weight in the appraisals of the capabilities of organizations while in practice they are considered as significant contributors in traditional process and organizational performance appraisals, as stressed instead in well-known Performance Management models such as MBQA, EFQM and BSC. This paper proposes some ways for leveraging people-related maturity issues merging HR practices from several types of maturity models into the organizational Business Process Model (BPM) in order to achieve higher organizational maturity and capability levels.

    The Inforare project aims to set up a system for the sharing of clinical and familial data, in order to study how genes are related to the severity of sickle cell disease. While the computerisation of clinical records represents a valuable research goal, an ethical framework is necessary to guarantee patients' protection and their rights in this developing field. Issues relating to patient information during the Inforare study were analysed by the steering committee. Several major concerns were discussed by the committee and formalized in the patients' information letter: educating patients to aid the recruitment of family members, rules of confidentiality and the disclosure of aggregate, individual and unexpected research results. This paper presents the main issues addressed.

    A comprehensive experimental program has been launched in order to gain new data in support of the severe accident studies related to the ASTRID demonstrator. The main new issues with respect to the historic experimental database are mainly related to new design options: heterogeneous core with thick pins; new materials; new severe accident mitigation systems such as - corium discharge channels; - core-catcher with sacrificial materials; - some issues remaining open as Fuel Coolant Interaction. Experiments are needed both in-pile and out of pile: - Depending on the objectives, the out of pile experiments can be conducted - with simulant; - with prototypic corium; - or with irradiated fuel. A new large scale corium facility, FOURNAISE, must be built to fulfill this program. Already, experimental R&D started in existing facilities, such as VITI or CORRONA

    2018-01-01

    On the Javalambre mountain in Spain, the Centro de Estudios de Fisica del Cosmos de Aragon has setup two telescopes, the JST/T250 and the JAST/T80. The JAST/T80 telescope integrates T80Cam, a large format, single CCD camera while the JST/T250 will mount the JPCam instrument, a 1.2Gpix camera equipped with a 14-CCD mosaic using the new large format e2v 9.2k×9.2k 10-μm pixel detectors. Both T80Cam and JPCam integrate a large number of filters in dimensions of 106.8×106.8 mm2 and 101.7×95.5 mm2, respectively. For this instrument, SCHOTT manufactured 56 specially designed steep edged bandpass interference filters, which were recently completed. The filter set consists of bandpass filters in the range between 348.5 and 910 nm and a longpass filter at 915 nm. Most of the filters have full-width at half-maximum (FWHM) of 14.5 nm and a blocking between 250 and 1050 nm with optical density of OD5. Absorptive color glass substrates in combination with interference filters were used to minimize residual reflection in order to avoid ghost images. In spite of containing absorptive elements, the filters show the maximum possible transmission. This was achieved by using magnetron sputtering for the filter coating process. The most important requirement for the continuous photometric survey is the tight tolerancing of the central wavelengths and FWHM of the filters. This insures each bandpass has a defined overlap with its neighbors. A high image quality required a low transmitted wavefront error (<λ/4 locally and <λ/2 on the whole aperture), which was achieved even by combining two or three substrates. We report on the spectral and interferometric results measured on the whole set of filters.

    As Internet and computers become widespread, health portals offering online health-related information become more popular. The most important point for health portals is presenting reliable and valid information. Besides, portal needs to be usable to be able to serve information to users effectively. This study aims to determine usability issues emerging when health-related information is searched on a health portal. User-based usability tests are conducted and eye movement analyses are used in addition to traditional performance measures. Results revealed that users prefer systematic, simple and consistent designs offering interactive tools. Moreover, content and partitions needs to be shaped according to the medical knowledge of target users.

    This paper discusses some technical issues identified from the seismic hazard analyses for probabilistic safety assessment on the operating Korean nuclear power plants and the related activities to resolve the issues. Since there are no strong instrumental earthquake records in Korea, the seismic hazard analysis is mainly dependent on the historical earthquake records. Results of the past seismic hazard analyses show that there are many uncertainties in attenuation function and intensity level and that there is a need to improve statistical method. The identification of the activity of the Yangsan Fault, which is close to nuclear power plant sites, has been an important issue. But the issue has not been resolved yet in spite of much research works done. Recently, some capable faults were found in the offshore area of Gulupdo Island in the Yellow Sea. It is anticipated that the results of research on both the Yangsan Fault and reduction of uncertainty in seismic hazard analysis will have an significant influence on seismic design and safety assessment of nuclear power plants in the future.

    In this work we predict the nonlinear behaviour of an eight-pole quasi-elliptic bandpass high temperature superconducting (HTS) filter with an equivalent circuit extracted from intermodulation measurements performed at the centre of the filter passband. We present measurements that show that the equivalent circuit is able to predict the intermodulation products produced by the filter when driven by two in-band or out-of-band sinusoidal signals. Numerical techniques based on harmonic balance are used to extract the elements of the equivalent circuit and to simulate its nonlinear performance

    We propose a novel photonic structure to implement a chirped single-bandpass microwave photonic filter based on the amplitude modulation of a broadband optical signal transmitted by a non-linear dispersive element and an interferometric system prior to balanced photodetection. A full reconfigurability of the filter is achieved since amplitude and phase responses can be independently controlled. We have experimentally demonstrated chirp values up to tens of ns/GHz, which is, as far as we know, one order of magnitude better than others achieved by electrical approaches and furthermore, without restrictions in terms of frequency tuning since a frequency operation range up to 40 GHz has been experimentally demonstrated.

    1979-11-01

    Estimates of Indian uranium resources range from 11 to 50% of the US total resources. About 17% of New Mexico's reserves are known to be on Indian lands. New Mexico has produced almost half of the nation's uranium supply; over half of the known reserves are located within the state. However, the state has virtually no jurisdiction over development of Indian uranium. As a result, economic and environmental impacts on the state are beyond its control. The lack of state and federal control over these impacts is influencing how the Indians allow development to proceed. The impacts of Indian uranium development also influence state control of non-Indian. To the extent that these controls affect the availability of uranium concentrate, DOE needs to understand the issues involved. This issue paper identifies some of the related problems for both the Indians and the state and explores the reasons behind them

    On 11 March 2011, the Great East Japan Earthquake and Tsunami hit the Fukushima Daiichi Nuclear Power Station. The Fukushima Daiichi Units 1-3 lost all DC and AC power supplies, which set in motion a chain of events that led to releases of radioactivity to the environment. Since then, TEPCO has made many efforts to investigate the accident progressions and the status of the reactors and containment vessels. However, there still exist several tens of unsolved issues to be investigated for the fully understanding of the accident. In this paper, we introduce the unsolved issues related to thermal-hydraulics in the suppression chamber during the Fukushima Daiichi accident progressions. Especially, in Units 2 and 3, there are possibilities that thermal stratification inside their suppression chambers played an important role. It is important that these phenomena are addressed following both theoretical and experimental approaches as support to severe accident simulations. (author)

    A variety of health-related genetic testing is currently advertized directly to consumers. This article provides a timely overview of direct-to-consumer genetic testing (DTC GT) and salient ethical issues, as well as an analysis of the impact of the recently adopted regulation on in vitro diagnostic medical devices on DTC GT. DTC GT companies currently employ new testing approaches, report on a wide spectrum of conditions and target new groups of consumers. Such activities raise ethical issues including the questionable analytic and clinical validity of tests, the adequacy of informed consent, potentially misleading advertizing, testing in children, research uses and commercialization of genomic data. The recently adopted regulation on in vitro diagnostic medical devices may limit the offers of predisposition DTC GT in the EU market.

    Research into post-wildfire effects began in the United States more than 70 years ago and only later extended to other parts of the world. Post-wildfire responses are typically transient, episodic, variable in space and time, dependent on thresholds, and involve multiple processes measured by different methods. These characteristics tend to hinder research progress, but the large empirical knowledge base amassed in different regions of the world suggests that it should now be possible to synthesize the data and make a substantial improvement in the understanding of post-wildfire runoff and erosion response. Thus, it is important to identify and prioritize the research issues related to post-wildfire runoff and erosion. Priority research issues are the need to: (1) organize and synthesize similarities and differences in post-wildfire responses between different fire-prone regions of the world in order to determine common patterns and generalities that can explain cause and effect relations; (2) identify and quantify functional relations between metrics of fire effects and soil hydraulic properties that will better represent the dynamic and transient conditions after a wildfire; (3) determine the interaction between burned landscapes and temporally and spatially variable meso-scale precipitation, which is often the primary driver of post-wildfire runoff and erosion responses; (4) determine functional relations between precipitation, basin morphology, runoff connectivity, contributing area, surface roughness, depression storage, and soil characteristics required to predict the timing, magnitudes, and duration of floods and debris flows from ungaged burned basins; and (5) develop standard measurement methods that will ensure the collection of uniform and comparable runoff and erosion data. Resolution of these issues will help to improve conceptual and computer models of post-wildfire runoff and erosion processes.

    Layered Synthetic Microstructures (LSMs) show great promise as focusing, high-throughput, hard x-ray monochromators. Experimental reflectivity vs. energy curves have been obtained on carbon-tungsten and carbon-molybdenum LSMs of up to 260 layers in thickness. Reflectivities for three flat LSMs with different bandpasses were 70% with δE/E = 5.4%, 66% with δE/E = 1.4%, and 19% with δE/E = 0.6%. A new generation of variable bandwidth optics using two successive LSMs is proposed. The first element will be an LSM deposited on a substrate that can be water cooled as it intercepts direct radiation from a storage ring. It can be bent for vertical focusing. The bandpass can be adjusted by choosing interchangeable first elements from an assortment of LSM's with different bandpasses (for example, δE/E = 0.005, 0.01, 0.02, 0.05, 0.1). The second LSM will consist of a multilayered structure with a 10% bandpass built onto a flexible substrate that can be bent for sagittal focusing. The result will be double focusing optics with an adjustable energy bandpass that are tunable from 5 to 30 keV

    This paper presents the design of two reduced size dual-band metamaterial bandpass filters and its simulation followed by measurements of proposed filters. These filters are supporting different frequency bands and primarily could be utilize in radio frequency identification (RFID) application. The filter includes three cells in which two are symmetrical and both inductively coupled with the third cell which is present in between them. In the proposed designs, three different metamaterial composite right/left handed (CRLH) cell resonators have been analysed for compactness. The CRLH cell consists of an interdigital capacitor, a stub/meander line/spiral inductor and a via to connect the top of the structure and ground plane. Finally, the proposed dual band bandpass filters (using meander line and spiral inductor) are showing size reduction by 65% and 50% (with 25% operating frequency reduction), respectively, in comparison with reference filter using stub inductor. More than 30 dB attenuation has been achieved between the two passbands.

    Hospital malnutrition is a relevant clinical issue present in about 50% of patients that is associated with increased morbidity, mortality, and cost of care. Because of the relation of malnutrition with chronic and acute inflammatory processes secondary to disease, nutrition therapy is considered an important medical treatment. However, there is little discussion about the impact of another critical issue related to hospital malnutrition, that is, lack of appropriate food or nutrition therapy given to the patients. Unnecessary fasting practices and the use of inappropriate nutrition prescriptions result in underfeeding that can be a related or direct cause of hospital malnutrition, independent of disease or inflammatory state. Suboptimal prescription of oral, enteral, and parenteral nutrition should be analyzed and discussed from an ethical perspective since this practice has the potential to harm patients. In addition, absence or inadequate provision of nutrition may present barriers for improved patient outcomes and could be prevented by simply recognizing lack of knowledge, skills, or experience in nutrition and entrusting nutrition prescription to interdisciplinary teams with clinicians well prepared in nutrition sciences. This article reviews potential barriers to the prevention or treatment of hospital malnutrition and proposes specific actions that can help clinicians to overcome and implement optimal nutrition not just as medical therapy but also as a basic comfort care that may help patients nutritionally, clinically, physically, and emotionally. © 2016 American Society for Parenteral and Enteral Nutrition.

    The authors comment on recent reviews of cardiovascular job strain research by P. L. Schnall and P. A. Landsbergis (1994), and by T. S. Kristensen (1995), which conclude that job strain as defined by the demand-control model (the combination of contributions of low job decision latitudes and high psychological job demands) is confirmed as a risk factor for cardiovascular mortality in a large majority of studies. Lack of social support at work appears to further increase risk. Several still-unresolved research questions are examined in light of recent studies: (a) methodological issues related to use of occupational aggregate estimations and occupational career aggregate assessments, use of standard scales for job analysis and recall bias issues in self-reporting; (b) confounding factors and differential strengths of association by subgroups in job strain-cardiovascular disease analyses with respect to social class, gender, and working hours; and (c) review of results of monitoring job strain-blood pressure associations and associated methodological issues.

    Photovoltaics technology is rapidly evolving towards a new generation of low-cost thin film technologies. One of the most promising materials in this new generation is copper indium selenide (CuInSe{sub 2} or CIS). As with any new material, successful commercialization of CIS photovoltaic (PV) technology will require attention to environmental, health and safety issues, including consideration of the sources, usage, and end-of-product-life disposal and/or recycling of the constituent materials. This work focuses on three specific environmental, health and safety (EH and S) issues related to CIS PV: (1) economics are analyzed to determine their impact on materials use and re-use; (2) Federal and California State environmental disposal and waste handling regulations are analyzed to evaluate their impact on PV module manufacturing and end-of-life module handling; and (3) the logistics and economics of product recycling and waste disposal by industries with comparable EH and S issues are examined to quantify the corresponding options available for handling, disposing of and/or recycling manufacturing by-products and end-of-life modules.

    We propose a hybrid circuit for spoof surface plasmon polaritons (SPPs) and spatial waveguide modes to develop new microwave devices. The hybrid circuit includes a spoof SPP waveguide made of two anti-symmetric corrugated metallic strips and a traditional substrate integrated waveguide (SIW). From dispersion relations, we show that the electromagnetic waves only can propagate through the hybrid circuit when the operating frequency is less than the cut-off frequency of the SPP waveguide and greater than the cut-off frequency of SIW, generating efficient band-pass filters. We demonstrate that the pass band is controllable in a large range by designing the geometrical parameters of SPP waveguide and SIW. Full-wave simulations are provided to show the large adjustability of filters, including ultra wideband and narrowband filters. We fabricate a sample of the new hybrid device in the microwave frequencies, and measurement results have excellent agreements to numerical simulations, demonstrating excellent filtering characteristics such as low loss, high efficiency, and good square ratio. The proposed hybrid circuit gives important potential to accelerate the development of plasmonic integrated functional devices and circuits in both microwave and terahertz frequencies.

    The pharmaceutical industry spends billions of dollars annually on direct-to-consumer advertising (DTCA). Patient perspectives on the impact of televised DTCA on health-related behaviors and issues were assessed by means of a 68-question survey. 58.6% of respondents believed that DTCA allowed consumers to have a more active role in managing their health. However, 27.6% felt DTCA caused confusion, and an alarming 17.8% of respondents stopped taking their medication because of concerns about serious side effects mentioned in DTCA. Overall, participants believed DTCA plays a useful role in health self-management; however, a considerable percentage thought that the cost outweighs the benefits.

    Development of low losses, small size and broad bandwidth microwave bandpass filter operating at higher frequencies is an active area of research. This paper presents a new route used to design and simulate microwave bandpass filter using finite element modelling and realized broad bandwidth, low losses, small dimension microwave bandpass filter operating at 10 GHz frequency using return loss method. The filter circuit has been carried out using Computer Aid Design (CAD), Ansoft HFSS software and designed with four parallel couple line model and small dimension (10 × 10 mm2) using LaAlO3 substrate. The response of the microwave filter circuit showed high return loss -50 dB at operating frequency at 10.4 GHz and broad bandwidth of 2.5 GHz from 9.5 to 12 GHz. The results indicate the filter design and simulation using HFSS is reliable and have the opportunity to transfer from lab potential experiments to the industry.

    2015-07-01

    The consequences of using publicly available social media applications specifically for healthcare purposes are largely unaddressed in current research. Where they are addressed, the focus is primarily on issues of privacy and data protection. We therefore use a case study of the first live Twitter heart operation in the Netherlands, in combination with recent literature on social media from other academic fields, to identify a wide range of ethical issues related to using social media for health-related purposes. Although this case reflects an innovative approach to public education and patient centeredness, it also illustrates the need for institutions to weigh the various aspects of use and to develop a plan to deal with these on a per case basis. Given the continual development of technologies, researchers may not yet be able to oversee and anticipate all of the potential implications. Further development of a research agenda on this topic, the promotion of guidelines and policies, and the publication of case studies that reveal the granularity of individual situations will therefore help raise awareness and assist physicians and institutions in using social media to support existing care services.

    Full Text Available The article presents a brief overview of India-U.S. relations during the period of Narendra Modi’s government and Barack Obama’s administration. The author analyzes the dynamics of cooperation development after the victory of Bharatiya Janata Party in the 2014 Parliamentary elections in India and studies the key directions of bilateral agenda. The current condition of India-U.S. strategic dialogue and the influence of human rights issues on the countries’ cooperation are characterized. Since 2014 the states’ cooperation has been growing rapidly. The bilateral investment, trade and economic interdependence have significantly increased. Some experts and mass media note that Barack Obama and Narendra Modi are having friendly relations. From a different angle, a number of agreements between countries still remain unaccomplished. For instance, the U.S. support for India’s permanent seat in the United Nations Security Council, its accession to APEC and the implementation of nuclear deal have yet to be turned into achievement. Together with strengthening the bilateral strategic dialogue, the U.S. has intensified the criticism of India’s human rights record. The main part of it includes the cases of religious intolerance, which are observed in the United States Commission on International Religious Freedom reports and the remarks given by U.S. lawmakers and official representatives, including the Ambassador to India. Washington’s careful attention to the human rights issues and religious violence in particular is one of the major irritants in the U.S.-India relations. The engagement of Indian Americans in the local U.S. politics and their lobbying efforts in the context of U.S.-India relations are revealed. The author outlines the near-terms perspectives of bilateral cooperation.

    Full Text Available The relationship between Kazakh people and the Dzhungar Khanate in the 17th - the first half of the 18th centuries was an important milestone in the development of Kazakh sovereignty. Kazakh Khanate had its own place in the development of international relations of the Central Asian countries. The historiography of this problem is very wide. For many years many researchers of post-Soviet, Western, Central Asian countries dedicated their work to this issue. Russian historiography is notable among others for its features. The article discusses some concepts of the modern Russian scientists regarding Kazakh-Dzhungarian relations. Russian historiography of Kazakh-Dzhungarian relations started to develop from the pre-revolutionary period and continues to these days. Kazakhstan scientists of the Soviet period also contributed to the study of international relations in Central Asia in the 17th-18th centuries in line with the required methodological and ideological direction. However, at present in connection with the sovereignization and becoming independent states of the post-Soviet countries, there is some differentiation in the areas of Russian and Kazakh social sciences and humanities. Today our society intentionally seeks to rethink the key milestones of the passed way, know itself and define its new place in the contemporary reality. Therefore, the Russian research on the history of international relations is especially relevant to the public

As families are burdened with the high cost of care for aging members, demand is increasing for medical care and nursing homes. Thus, medication management is crucial to ensure that residents in a care center benefit and assist the management of the care center in reducing the burden of health care. This study is aimed to qualitatively explore issues related to medication management in residential aged care facilities (RACFs.Participants and methods: A total of 11 stakeholders comprising health care providers, administrators, caretakers and residents were recruited from a list of registered government, nongovernmental organization and private RACFs in Malaysia from September 2016 to April 2017. An exploratory qualitative study adhering to Consolidated Criteria for Reporting Qualitative Studies was conducted. In-depth interview was conducted with consent of all participants, and the interviews were audio recorded for later verbatim transcription. Observational analysis was also conducted in a noninterfering manner.Results and discussion: Three themes, namely medication use process, personnel handling medications and culture, emerged in this study. Medication use process highlighted an unclaimed liability for residents’ medication by the RACFs, whereas personnel handling medications were found to lack sufficient training in medication management. Culture of the organization did affect the medication safety and quality improvement. The empowerment of the residents in their medication management was limited. There were unclear roles and responsibility of who manages the medication in the nongovernment-funded RACFs, although they were well structured in the private nursing homes.Conclusion: There are important issues

    The purpose of this scoping review was to determine the health-equity issues that relate to childhood obesity. Health-equity issues related to childhood obesity were identified by analyzing food environment, natural and built environment, and social environment. The authors searched Medline, PubMed, and Web of Science, using the keywords "children" and "obesity." Specific terms for each environment were added: "food desert," "advertising," "insecurity," "price," "processing," "trade," and "school" for food environment; "urban design," "land use," "transportation mode," "public facilities," and "market access" for natural and built environment; and "financial capacity/poverty," "living conditions," "transport access," "remoteness," "social support," "social cohesion," "working practices," "eating habits," "time," and "social norms" for social environment. Inclusion criteria were studies or reports with populations under age 12, conducted in the United States, and published in English in 2005 or later. The final search yielded 39 references (16 for food environment, 11 for built environment, and 12 for social environment). Most food-environment elements were associated with obesity, except food insecurity and food deserts. A natural and built environment that hinders access to physical activity resources and access to healthy foods increased the risk of childhood obesity. Similarly, a negative social environment was associated with childhood obesity. More research is needed on the effects of food production, living conditions, time for shopping, and exercise, as related to childhood obesity. Most elements of food, natural and built, and social-environments were associated with weight in children under age 12, except food insecurity and food deserts. © 2017 American Association of Public Health Dentistry.

    The purpose of this study was to determine the current level of knowledge and awareness of hunger-related issues among a convenience sample of Delawareans. We also assessed whether raising knowledge and awareness of the hunger problem through the FBD's newly designed web site would encourage participation in antihunger activities. Via e-mail, 1,719 individuals were invited to participate in a three-phase, online survey, and 392 agreed. Phase-I questions were answered prior to viewing the web site, phase II (n=217) immediately afterward, and phase III (n=61) six weeks later. Responses indicated a high level of awareness about general hunger issues but specific knowledge proved to be at a lower level. No statistically significant differences were noted when data were collapsed across gender, age, educational level, or work setting. In a six-week post-survey, 41% of subjects were motivated by the web site to engage in an antihunger activity; 34% had told others about the web site and indicated it may be a useful tool in antihunger outreach efforts for the FBD.

    Fusion power holds the promise of electricity production with a high degree of safety and low environmental impact. Favourable characteristics of fusion as an energy source provide the potential for this very good safety and environmental performance. But to fully realize the potential, attention must be paid in the design of a demonstration fusion power plant (DEMO) or a commercial power plant to minimize the radiological hazards. These hazards arise principally from the inventory of tritium and from materials that become activated by neutrons from the plasma. The confinement of these radioactive substances, and prevention of radiation exposure, are the primary goals of the safety approach for fusion, in order to minimize the potential for harm to personnel, the public, and the environment. The safety functions that are implemented in the design to achieve these goals are dependent on the performance of a range of materials. Degradation of the properties of materials can lead to challenges to key safety functions such as confinement. In this paper the principal types of material that have some role in safety are recalled. These either represent a potential source of hazard or contribute to the amelioration of hazards; in each case the related issues are reviewed. The resolution of these issues lead, in some instances, to requirements on materials specifications or to limits on their performance.

    This paper aims at listing the methods used to evaluate the usability of medication-related alerting functions and at knowing what type of usability issues those methods allow to detect. A sub-analysis of data from this systematic review has been performed. Methods applied in the included papers were collected. Then, included papers were sorted in four types of evaluation: "expert evaluation", "user- testing/simulation", "on site observation" and "impact studies". The types of usability issues (usability flaws, usage problems and negative outcomes) uncovered by those evaluations were analyzed. Results show that a large set of methods are used. The largest proportion of papers uses "on site observation" evaluation. This is the only evaluation type for which every kind of usability flaws, usage problems and outcomes are detected. It is somehow surprising that, in a usability systematic review, most of the papers included use a method that is not often presented as a usability method. Results are discussed about the opportunity to provide usability information collected after the implementation of the technology during their design process, i.e. before their implementation.

    The waste management activities at ORNL related to the decontamination and decommissioning (D ampersand D) of radioactively contaminated buildings are divided into four categories: Operational facilities, inactive or surplus facilities, future facilities planning, and D ampersand D activities. This paper only discusses regulatory issues related to inactive or surplus facilities. Additionally, rather than attempting to address all resulting waste streams and related regulations, this paper highlights only a few of the ORNL waste streams that present key regulatory issues

  11. How to govern physician-hospital exchanges: contractual and relational issues in Belgian hospitals.

    Trybou, Jeroen; Gemmel, Paul; Annemans, Lieven

    2014-07-01

    Our aim was to investigate contractual mechanisms in physician-hospital exchanges. The concepts of risk-sharing and the nature of physician-hospital exchanges - transactional versus relational - were studied. Two qualitative case studies were performed in Belgium. Hospital executives and physicians were interviewed to develop an in-depth understanding of contractual and relational issues that shape physician-hospital contracting in acute care hospitals. The underlying theoretical concepts of agency theory and social exchange theory were used to analyse the data. Our study found that physician-hospital contracting is highly complex. The contract is far more than an economic instrument governing financial aspects. The effect of the contract on the nature of exchange - whether transactional or relational - also needs to be considered. While it can be argued that contractual governance methods are increasingly necessary to overcome the difficulties that arise from the fragmented payment framework by aligning incentives and sharing financial risk, they undermine the necessary relational governance. Relational qualities such as mutual trust and an integrative view on physician-hospital exchanges are threatened, and may be difficult to sustain, given the current fragmentary payment framework. Since health care policy makers are increasing the financial risk borne by health care providers, it can be argued that this also increases the need to share financial risk and to align incentives between physician and hospital. However, our study demonstrates that while economic alignment is important in determining physician-hospital contracts, the corresponding impact on working relationships should also be considered. Moreover, it is important to avoid a relationship between hospital and physician predominantly characterized by transactional exchanges thereby fostering an unhealthy us-and-them divide and mentality. Relational exchange is a valuable alternative to contractual

  12. Metamaterial composite bandpass filter with an ultra-broadband rejection bandwidth of up to 240 terahertz

    2014-01-01

    We present a metamaterial, consisting of a cross structure and a metal mesh filter, that forms a composite with greater functional bandwidth than any terahertz (THz) metamaterial to date. Metamaterials traditionally have a narrow usable bandwidth that is much smaller than common THz sources......, such as photoconductive antennas and difference frequency generation. The composite structure shown here expands the usable bandwidth to exceed that of current THz sources. To highlight the applicability of this combination, we demonstrate a series of bandpass filters with only a single pass band, with a central...... frequency (f) that is scalable from 0.86–8.51 THz, that highly extinguishes other frequencies up to >240 THz. The performance of these filters is demonstrated in experiment, using both air biased coherent detection and a Fourier transform infrared spectrometer (FTIR), as well as in simulation. We present...

    Solar-blind ultraviolet (UV) band-pass filter has significant value in many scientific, commercial, and military applications, in which the detection of weak UV signal against a strong background of solar radiation is required. In this work, a solar-blind filter is designed based on the concept of “transparent metal”. The filter consisting of Al/SiO 2 multilayers could exhibit a high transmission in the solar-blind wavelength region and a wide stopband extending from near-ultraviolet to infrared wavelength range. The central wavelength, bandwidth, Q factor, and rejection ratio of the passband are numerically studied as a function of individual layer thickness and multilayer period.

    Weiping Li

    2016-01-01

    Full Text Available In this article, a compact narrow-bandpass filter with high selectivity and improved rejection level is presented. For miniaturization, a pair of double negative (DNG cells consisting of quasi-planar chiral resonators are cascaded and electrically loaded to a microstrip transmission line; short ended stubs are introduced to expand upper rejection band. The structure is analyzed using equivalent circuit models and simulated based on EM simulation software. For validation, the proposed filter is fabricated and measured. The measured results are in good agreement with the simulated ones. By comparing to other filters in the references, it is shown that the proposed filter has the advantage of skirt selectivity and compact size, so it can be integrated more conveniently in modern wireless communication systems and microwave planar circuits.

  15. A planar and tunable bandpass filter on a ferrite substrate with integrated windings

    KAUST Repository

    Arabi, Eyad A.

    2015-05-01

    Tunable Filters that are based on ferrite materials are often biased by external magnets or coils which are large and bulky. In this work a completely planar, CPW-based bandpass filter is presented with integrated windings. Due to these windings the size of the filter is only 26mm × 34mm × 0.38mm which is orders of magnitude smaller than the traditional designs with external windings. The filter is realized by electroplating of Copper over seed layers of Titanium and Gold over a YIG substrate. The fabricated filter achieves a tunability of 3.4% without any external magnets or coils. A good insertion loss of 2.3 dBs and rejection greater than 50 dBs have been obtained. To the best of the authors knowledge, this design is the first ferrite-based design that is completely planar and self-biased.

    Full Text Available Two new microstrip triple-mode resonators loaded with T-shaped open stubs using axially and centrally symmetric spiral structures, respectively, are presented. Spiraled for circuit size reduction, these two half-wavelength resonators can both generate three resonant modes over a wide frequency band by loading two T-stubs with different lengths. Due to the structural symmetry, they can be analyzed by odd- and even-mode method. To validate the design concept, two compact bandpass filters (BPFs using these two novel resonators with center frequencies of 1.76 GHz and 2.44 GHz for the GSM1800 and WLAN/Zigbee applications, respectively, have been designed, fabricated and tested. The center frequencies and bandwidths can be tunable through the analysis of resonant frequency responses, fractional bandwidths and external quality factor versus the resonator parameters. The final measured results have achieved good consistence with the simulations of these two BPFs.

    This paper presents a novel second-order dual-band bandpass filter (BPF) by using proposed stubs loaded ring resonator. The resonant behavior of proposed stubs loaded ring resonator is analyzed by even-/odd-mode method, which shows its multiple-mode resonant characteristic. Parameters sweep is done so as to give the design guidelines. As an example, a second-order dual-band BPF operating at 1.8/5.2 GHz for GSM and WLAN applications is designed, fabricated and measured. The fabricated filter has a very compact size of 0.05λg×0.15λg. Measured results also show that the proposed dual-band BPF has a better than 20 dB rejection upper stopband from 5.47 GHz to 12.56 GHz. Good agreement is shown between the simulated and measured results.

    The lack of a clearly defined content or structure provided the opportunity to transform a one-credit, pass-fail senior seminar course into a meaningful capstone experience for chemistry and biochemistry majors. In addition to individual and class exercises associated with employment, graduate school, communication skills, and professional ethics, small groups of students worked together to create informative Web sites that took positions on important societal issues related to chemistry. Each group presented a seminar and responded to questions from their peers and two or more unannounced visitors, "wild cards" who often had expertise in the seminar topic. Throughout the course, the instructors placed particular emphasis on developing students' ability to work cooperatively, locate and evaluate information, make informed judgments based on available information, and logically develop and defend their positions. Input from a retired industrial chemist helped define these skill elements.

    The ice conditions in the north Caspian Sea are challenging for the Kashagan field development. The climatic conditions of the area are extreme, with cold winters (-30 degrees C) and hot summers (+40 degrees C). The presence and the quantity of ice are also highly variable from year to year. This paper investigated the major ice-related issues affecting the Kashagan structures and pipelines. An extensive description of the ice environment was provided. Ice design criteria for the offshore rock islands, the pipelines and the layout of the ice protection barriers around the islands were presented. It was found that the ice design methods used in Arctic areas have required some adaptations to meet Caspian conditions. All the islands were designed with an ice encroachment zone to reduce the hazardous effect of the ice rubble encroaching. Rock sloped barriers and steel barriers were implanted around the islands to protect the logistical areas.

    Globally, the population of older people is on the rise. As families are burdened with the high cost of care for aging members, demand is increasing for medical care and nursing homes. Thus, medication management is crucial to ensure that residents in a care center benefit and assist the management of the care center in reducing the burden of health care. This study is aimed to qualitatively explore issues related to medication management in residential aged care facilities (RACFs). A total of 11 stakeholders comprising health care providers, administrators, caretakers and residents were recruited from a list of registered government, nongovernmental organization and private RACFs in Malaysia from September 2016 to April 2017. An exploratory qualitative study adhering to Consolidated Criteria for Reporting Qualitative Studies was conducted. In-depth interview was conducted with consent of all participants, and the interviews were audio recorded for later verbatim transcription. Observational analysis was also conducted in a noninterfering manner. Three themes, namely medication use process, personnel handling medications and culture, emerged in this study. Medication use process highlighted an unclaimed liability for residents' medication by the RACFs, whereas personnel handling medications were found to lack sufficient training in medication management. Culture of the organization did affect the medication safety and quality improvement. The empowerment of the residents in their medication management was limited. There were unclear roles and responsibility of who manages the medication in the nongovernment-funded RACFs, although they were well structured in the private nursing homes. There are important issues related to medication management in RACFs which require a need to establish policy and guidelines.

    Summary Many symptoms of neurologic or psychiatric illness—such as cognitive impairment, depression, anxiety, attention deficits, and migraine—occur more frequently in people with epilepsy than in the general population. These diverse comorbidities present an underappreciated problem for people with epilepsy and their caregivers because they decrease quality of life, complicate treatment, and increase mortality. In fact, it has been suggested that comorbidities can have a greater effect on quality of life in people with epilepsy than the seizures themselves. There is increasing recognition of the frequency and impact of cognitive and behavioral comorbidities of epilepsy, highlighted in the 2012 Institute of Medicine report on epilepsy. Comorbidities have also been acknowledged, as a National Institutes of Health (NIH) Benchmark area for research in epilepsy. However, relatively little progress has been made in developing new therapies directed specifically at comorbidities. On the other hand, there have been many advances in understanding underlying mechanisms. These advances have made it possible to identify novel targets for therapy and prevention. As part of the International League Against Epilepsy/American Epilepsy Society workshop on preclinical therapy development for epilepsy, our working group considered the current state of understanding related to terminology, models, and strategies for therapy development for the comorbidities of epilepsy. Herein we summarize our findings and suggest ways to accelerate development of new therapies. We also consider important issues to improve research including those related to methodology, nonpharmacologic therapies, biomarkers, and infrastructure. PMID:23909853

  6. Complexity Triggered by Economic Globalisation— The Issue of On-Line Betting-Related Match Fixing

    2017-02-01

    Full Text Available Complexity in mainstream economics consists in high intermediary consumption of mathematics. A new approach to complexity economics dwells upon path-dependent global systems; their emergence and evolving organisation. The focus here is on the complexity of the real economic world due to globalisation. On-line betting related match-fixing is a case in point about which the article presents non-exhaustive empirical evidence and shows how it is analysed with the standard model of the economics of crime. There is no room for complexity in such an individualistic approach to corrupt behaviour applied to bet-related fixes. A more complex model is sketched based on interactions between a global (though underground market for fixes and the actual partly legal, partly illegal global sport betting market. These interactions exhibit how complex is the issue of combating betting-related match fixing. Reviewing those major policies envisaged for containing the latter—prohibition; sanctions; regulation; privatisation (betting rights—the article opts for a global ‘Sportbettobin’ tax on sport betting gains; in the same vein as the famous Tobin tax on international capital transfers. The novelty in this approach is a variable (increasing rate applied to increasing tranches of taxation (gains which should dry up the worst cases of on-line bettingrelated match fixing.

  8. Fabrication of Compact Microstrip Line-Based Balun-Bandpass Filter with High Common-Mode Suppression

    Directory of Open Access Journals (Sweden)

    Chia-Mao Chen

    2014-01-01

    Full Text Available A new type of balun-bandpass filter was proposed based on the traditional coupled-line theory and folded open-loop ring resonators (OLRRs configuration. For that, a new device with both filter-type and balun-type characteristics was investigated and fabricated. Both magnetic and electric coupling structures were implemented to provide high performance balun-bandpass responses. The fabricated balun-bandpass filters had a wide bandwidth more than 200 MHz and a low insertion loss less than 2.51 dB at a center frequency of 2.6 GHz. The differences between the two outputs were below 0.4 dB in magnitude and within 180 ± 7° in phase. Also, the balun-bandpass filter presented an excellent common-mode rejection ratio over 25 dB in the passband. An advanced design methodology had been adopted based on EM simulation for making these designed parameters of OLRRs, microstrip lines, and open stubs. The measured frequency responses agreed well with simulated ones.

    Full text of publication follows: On June 9, 2003 the US NRC issued Bulletin No. 2003-01 that deals with the potential impact of debris blockage on containment sump recirculation at PWRs during a Loss-of-Coolant Accident (LOCA). In response to the bulletin, the Omaha Public Power District (OPPD) is in the process of developing procedural and operational strategies for their Fort Calhoun Station (FCS) to address the issues raised. Westinghouse provided engineering support to OPPD in identifying and resolving issues related to alternative means of supplying safety injection water to the reactor coolant system (RCS) in the absence of containment sump recirculation. Nuclear power plants are designed to protect the core following a LOCA by providing a continuous supply of cooling water to the core. In the long term, the Refueling Water Storage Tank (RWST) inventory will be depleted and core heat removal accomplished via recirculation of water previously injected into the Reactor Coolant System (RCS) and collected in the containment sump. Debris generated within the containment as a result of the impingement of fluid jets in the Zone of Influence (ZOI) of the RCS break and containment wash down may find its way into the containment sump. As the safety injection pumps take suction from the sump, in the recirculation mode of operation, the debris suspended in the sump water could begin to accumulate in the sump screen that is located in the recirculation path. Should sufficient debris accumulate on the sump screen, a flow blockage could potentially develop. This would result in insufficient safety injection pump NPSH, thereby impairing the recirculation mode of injection into RCS. Potential debris blockage and prevention of sump recirculation may be addressed by refilling the RWST with water and injecting this water directly into the core. This paper identifies and attempts to resolve several issues related to this alternative mode of RCS injection. In particular, the

    In September 1990, Martin Marietta Energy Systems (Energy Systems) discovered high levels of Cesium-137 present in surface sediments at the mouth of White Oak Creek (WOC) Embayment. WOC receives the majority of surface water drainage from Oak Ridge National Laboratory. Following this discovery, the Department of Energy (DOE) and Energy Systems pursued stabilizing sediment migration under provisions of the National Contingency Plan (NCP) Section 300.400 et. seq. as a time-critical removal action. However, significant uncertainty exists concerning the applicability of NCP procedural requirements designed for conducting US EPA-led, Superfund-financed response actions, because NCP Subpart K dealing with response actions at federal facilities has not been promulgated. In addition, relatively new guidance exists from DOE concerning National Environmental Policy Act documentation requirements for categorical exclusions associated with conducting removal actions at DOE facilities. A proactive approach was taken to identify issues and involve appropriate state and federal regulatory agencies. This approach required achieving consensus among all involved parties and identification of all applicable or relevant and appropriate regulatory requirements related to the removal action. As a result, this project forms a framework for conducting future time-critical removal actions at federal facilities

    The long-term effects of many drugs are unknown. Established risks are communicated to patients who participate in clinical trials during the informed consent process. However, unknown and unanticipated side effects of medications may occur years after treatment. Patients with metastatic bone cancer experience an imbalance between tumor cells and the bone marrow microenvironment. Increased cytokine release, osteoclastic activity, and uncoupled osteoblastic activity lead to weakened bone structure and osteolytic lesions. The bisphosphonates are a class of drugs available in IV and oral formulations to treat and prevent bone loss and decrease the risk of skeletal-related events. Intravenous bisphosphonates such as zoledronic acid and pamidronate disodium are approved by the US Food and Drug Administration for the treatment of bone pain and hypercalcemia of malignancy and the prevention of painful bone fractures in patients with metastatic bone cancer. Oral bisphosphonates such as alendronate, risedronate, and etidronate are used to reduce the risk of skeletal fractures in patients with osteoporosis and in breast cancer. Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a rare but painful complication of treatment characterized by infection, exposed bone, and poor wound healing. In this article, we discuss BRONJ and identify past, present, and future ethical and legal issues surrounding bisphosphonate administration.

    The most important contributions of radiation chemistry to some selected technological issues related to water-cooled reactors, reprocessing of spent nuclear fuel and high-level radioactive wastes, and fuel evolution during final radioactive waste disposal are highlighted. Chemical reactions occurring at the operating temperatures and pressures of reactors and involving primary transients and stable products from water radiolysis are presented and discussed in terms of the kinetic parameters and radiation chemical yields. The knowledge of these parameters is essential since they serve as input data to the models of water radiolysis in the primary loop of light water reactors and super critical water reactors. Selected features of water radiolysis in heterogeneous systems, such as aqueous nanoparticle suspensions and slurries, ceramic oxides surfaces, nanoporous, and cement-based materials, are discussed. They are of particular concern in the primary cooling loops in nuclear reactors and long-term storage of nuclear waste in geological repositories. This also includes radiation-induced processes related to corrosion of cladding materials and copper-coated iron canisters, dissolution of spent nuclear fuel, and changes of bentonite clays properties. Radiation-induced processes affecting stability of solvents and solvent extraction ligands as well oxidation states of actinide metal ions during recycling of the spent nuclear fuel are also briefly summarized.

    With the political tinge it has recently acquired, natural gas has taken a central position in the relations between the EU and Russia Besides energy security, the issue has three levels: the first is the opening of markets or the maintaining of monopolies, as much in Russia as in the European Union. The line of fracture is complex, and at present, in spite of rhetoric support on the opening of markets, it is rather their protection which is on the agenda. The second level is that of energy diplomacy Brussels and Moscow come face to face primarily in Central Asia, on the basis of interests and using diametrically opposite instrument. However, their policies are characterised by weighty constraints. The third level is that of the fight against climatic change. Soaring in this field, there are several convergencies between the policies of Brussels and Moscow, particularly in terms of energy efficiency. With this new order, gas could watch itself grow in significance, or otherwise drop, in which case the relation between the EU and Russian would not go uninfluenced. (author)

    The Hanford Site has 149 single-shell tanks (SSTs) containing radioactive wastes that are complex mixes of radioactive and chemical products. Active use of these SSTs was phased out completely by November 1980, and the first step toward final disposal of the waste in the SSTs is interim stabilization, which involves removing essentially all of the drainable liquid from the tank. Stabilization can be achieved administratively, by jet pumping to remove drainable interstitial liquid, or by supernatant pumping. To date, 116 tanks have been declared interim stabilized; 44 SSTs have had drainable liquid removed by salt well jet pumping. Of the 149 SSTs, 19 are on the Flammable Gas Watch List (FGWL) because the waste in these tanks is known or suspected, in all but one case, to generate and retain mixtures of flammable gases, including; hydrogen, nitrous oxide, and ammonia. Salt well pumping to remove the drainable interstitial liquid from these SSTs is expected to cause the release of much of the retained gas, posing a number of safety concerns. The scope of this work is to collect and summarize information, primarily tank data and observations, that relate salt well pumping to flammable gas safety issues. While the waste within FGWL SSTs is suspected offering flammable gases, the effect of salt well pumping on the waste behavior is not well understood. This study is being conducted for the Westinghouse Hanford Company as part of the Flammable Gas Project at the Pacific Northwest National Laboratory (PNNL). Understanding the historical tank behavior during and following salt well pumping will help to resolve the associated safety issues

    2018-05-01

    The methods for increasing gas-turbine aircraft engines' (GTE) adaptive properties to interference based on empowerment of automatic control systems (ACS) are analyzed. The flow pulsation in suction and a discharge line of the compressor, which may cause the stall, are considered as the interference. The algorithmic solution to the problem of GTE pre-stall modes’ control adapted to stability boundary is proposed. The aim of the study is to develop the band-pass filtering algorithms to provide the detection functions of the compressor pre-stall modes for ACS GTE. The characteristic feature of pre-stall effect is the increase of pressure pulsation amplitude over the impeller at the multiples of the rotor’ frequencies. The used method is based on a band-pass filter combining low-pass and high-pass digital filters. The impulse response of the high-pass filter is determined through a known low-pass filter impulse response by spectral inversion. The resulting transfer function of the second order band-pass filter (BPF) corresponds to a stable system. The two circuit implementations of BPF are synthesized. Designed band-pass filtering algorithms were tested in MATLAB environment. Comparative analysis of amplitude-frequency response of proposed implementation allows choosing the BPF scheme providing the best quality of filtration. The BPF reaction to the periodic sinusoidal signal, simulating the experimentally obtained pressure pulsation function in the pre-stall mode, was considered. The results of model experiment demonstrated the effectiveness of applying band-pass filtering algorithms as part of ACS to identify the pre-stall mode of the compressor for detection of pressure fluctuations’ peaks, characterizing the compressor’s approach to the stability boundary.

    1999-01-01

    This paper will present comparisons of the economics of MOX versus UO 2 fuels. In addition to the economics of the front end, the scope of the comparison will include the back end of the fuel cycle. Management of spent MOX fuel assemblies presents utilities with some technical issues that can complicate spent fuel pool operation. Alternative spent fuel management methods, such as dry storage of spent MOX fuel assemblies, will also be discussed. Differences in decay heat loads versus time for spent MOX and UO 2 fuel assemblies will be presented. This difference is one of the main problems confronting spent fuel managers relative to MOX. The difference in decay heat loads will serve as the basis for a performance overview of the various spent fuel technologies available today. The economics of the front end of MOX will be presented relative to UO 2 fuel. Availability of MOX manufacturing capability will also be discussed, along with a discussion of its impact on future MOX fabrication prices. The in-core performance of MOX will be compared to that of UO 2 fuel with similar performance characteristics. The information will include highlights of nuclear design and related operational considerations such as: Reactivity reduction with burnup is slower for MOX fuel than for UO 2 fuel; Spectral hardening resulting in lower control rod worths and a lower soluble boron worth; and more negative moderator, void and fuel temperature coefficients. A comparison of Westinghouse and ABB-CE core designs for use on disposition of weapons MOX in 12- and 18-month cycles will be presented. (author)

  17. Issues of work intensity, pace, and sustainability in relation to work context and nutritional status.

    Panter-Brick, Catherine

    2003-01-01

    This article raises issues about work intensity, pace, and sustainability during physical activity, focusing attention on the nature of work in labor-intensive societies, the management of exertion in habitual tasks, and the health and broad socioeconomic correlates of alternative ways to regulate work patterns. At the heart of this review are concerns to document human adaptability (in terms of the physical and behavioral management of heavy work) and to renew debate regarding the conceptualization and measurement of work intensity (variously evaluated in absolute or relative terms, as indexed by oxygen consumption, energy expenditure, percentage maximal work capacity, heart rate elevation, time and motion indicators, or physiological cost). Three questions are examined: Is heavy work primarily a matter of time or energy intensity? How is heavy work habitually sustained? What is the bigger picture relating work performance to work context and to nutritional or health status? It is argued that many arduous activities, such as carrying loads, demand endurance over time rather than intensive effort per unit time, and that work pace management lies in regulating both the rate of work and the time in rest during physical activity. Furthermore, strategies that maximize long-term endurance (adopted by "tortoises") and those that maximize short-term productivity (adopted by "hares") are appropriate to different work contexts (e.g., a subsistence or wage-labor economy) and suit individuals with different health status and ability. Thus, work intensity is an important aspect of the links between physical activity, health, productivity, and society, as noted in literature reviewing objectives for sustainable development and public health messages for disease risk management. These areas of scholarship are underresearched, partly because consensus has been slow in agreeing on which are the best measures of work pace and work intensity for use in field situations, and which

    Full Text Available I report, emphasizing some key open issues and some aspects that are particularly relevant for phenomenology, on the status of the development of “doubly-special” relativistic (“DSR” theories with both an observer-independent high-velocity scale and an observer-independent small-length/large-momentum scale, possibly relevant for the Planck-scale/quantum-gravity realm. I also give a true/false characterization of the structure of these theories. In particular, I discuss a DSR scenario without modification of the energy-momentum dispersion relation and without the қ-Poincaré Hopf algebra, a scenario with deformed Poincaré symmetries which is not a DSR scenario, some scenarios with both an invariant length scale and an invariant velocity scale which are not DSR scenarios, and a DSR scenario in which it is easy to verify that some observable relativistic (but non-special-relativistic features are insensitive to possible nonlinear redefinitions of symmetry generators.

    1993-01-01

    The operating uranium enrichment gaseous diffusion plants (GDPs) in Portsmouth, Ohio and Paducah, Kentucky, which are operated for the United States Department for Energy by Martin Marietta Energy Systems (MMES), currently use a chlorofluorocarbon (CFC-114) as the primary process stream coolant. Due to recent legislation embodied in the Clean Air Act, the production of this and other related chlorofluorocarbons (CFCS) are to be phased out with no production occurring after 1995. Since the plants lose approximately 500,000 pounds per year of this process stream coolant through various leaks, the GDPs are faced with the challenge of identifying a replacement coolant that will allow continued operation of the plants. MMES formed the CFC Task Team to identify and solve the various problems associated with identifying and implementing a replacement coolant. This report includes a review of the work performed by the CFC Task Team, and recommendations that were formulated based on this review and upon original work. The topics covered include; identifying a replacement coolant, coolant leak detection and repair efforts, coolant safety concerns, coolant level sensors, regulatory issues, and an analytical decision analysis

    Xylitol is a pentahydroxy sugar-alcohol which exists in a very low quantity in fruits and vegetables (plums, strawberries, cauliflower, and pumpkin). On commercial scale, xylitol can be produced by chemical and biotechnological processes. Chemical production is costly and extensive in purification steps. However, biotechnological method utilizes agricultural and forestry wastes which offer the possibilities of economic production of xylitol by reducing required energy. The precursor xylose is produced from agricultural biomass by chemical and enzymatic hydrolysis and can be converted to xylitol primarily by yeast strain. Hydrolysis under acidic condition is the more commonly used practice influenced by various process parameters. Various fermentation process inhibitors are produced during chemical hydrolysis that reduce xylitol production, a detoxification step is, therefore, necessary. Biotechnological xylitol production is an integral process of microbial species belonging to Candida genus which is influenced by various process parameters such as pH, temperature, time, nitrogen source, and yeast extract level. Xylitol has application and potential for food and pharmaceutical industries. It is a functional sweetener as it has prebiotic effects which can reduce blood glucose, triglyceride, and cholesterol level. This review describes recent research developments related to bioproduction of xylitol from agricultural wastes, application, health, and safety issues.

    Guidelines for the safe discharge of thermal effluents in aquatic environmental systems both surface water and marine coastal out falls has become very relevant to Indian environmental conditions with its rich biodiversity. While aquatic ecology may form the basis for such guidelines, the need for regulatory approach to the related issues has become the prime mover in thermal discharge problems. This is more so since the impacts considered are under short term and long term exposure conditions where the bio acclimatization and thermal stress factors may come to cross roads. Constant temperatures and cyclic temperature elevations also causes differential thermal stress which could be site specific. The recent notification by the Ministry of Environment and Forest (MoEF) revising the temperature limit for discharge of condenser cooling water from thermal power plants into coastal areas using sea water from 5 deg to 7 degC over and above the ambient temperature of the receiving water bodies. Discussions on whether the limiting temperature is to be achieved at the point of discharge or within a specified zone of the thermal plume is currently being debated. The act also stipulates installation of cooling towers using water from rivers, lakes and reservoirs irrespective of the plant location and capacity. For existing thermal plants the rise in temperature of the condenser cooling water from inlet to the let of the condenser shall not be more than 10 degC. (author)

  3. Containment Emergency Sump Performance. Technical findings related to Unresolved Safety Issue A-43. Revision 1

    International Nuclear Information System (INIS)

    1985-10-01

    This report summarizes key technical findings related to Unresolved Safety Issue (USI) A-43, Containment Emergency Sump Performance. Both BWRs and PWRs are considered in this report. Emergency core cooling systems require a clean, reliable water source to maintain long-term recirculation following a loss-of-coolant accident (LOCA). PWRs rely on the containment emergency sump to provide such a water supply to residual heat removal pumps and containment spray pumps. BWRs rely on pump suction intakes in the suppression pool or wet well to provide water to residual heat removal and core spray systems. Thus, the technical findings in this report provide information on post-LOCA recirculation. These findings have been derived from extensive experimental studies, generic plant studies, and assessments of sumps used for long-term cooling. Results of hydraulic tests have shown that the potential for air ingestion is less severe than previously hypothesized. The effects of debris blockage on NPSH margin must be dealt with on a plant-specific basis. These findings have been used to develop revisions to Regulatory Guide 1.82 and Standard Review Plan Section 6.2.2 (NUREG-0800)

    The news media are an important source of dietary information. Understanding news content, particularly the portrayal of risks and benefits of certain foods, is relevant for effective public health communication. Fish consumption may reduce risk for CVD and aid neonatal development, but recent work shows public confusion about the benefits of fish, challenged by the evidence of mercury and other contaminants in fish. We present an analysis of the messages about fish in US news media over 15 years, identifying trends in coverage and highlighting implications of current messaging. We conducted a descriptive text analysis and coded for manifest content: locality of focus, story frame, reference to studies, inclusion of government guidelines and portrayal of uncertainty. We identified chronological patterns and analysed the data for statistically significant relationships between media source and content. News stories were selected from five daily newspapers and five television networks (1993-2007). We analysed 310 health-related news stories on fish. Risk messages outweighed benefit messages four to one, and health benefits only became prominent after 2002. No difference existed in coverage topic by news source. Fish consumption has increasingly become a national issue. With the bulk of messages about fish consumption focused on risk, the benefits may be lost to consumers. This gap creates a need for public health to work with news media to more effectively communicate benefits and risks around fish consumption and health and to consider options for communicating tailored information where it can be more readily utilised.

    With the increasing recognition and application of casemix for managing and financing healthcare resources, the evaluation of alternative versions of systems such as diagnosis-related groups (DRGs) has been afforded high priority by governments and researchers in many countries. Outside the United States, an important issue has been the perceived need to produce local versions, and to establish whether or not these perform more effectively than the US-based classifications. A discussion of casemix evaluation criteria highlights the large number of measures that may be used, the rationale and assumptions underlying each measure, and the problems in interpreting the results. A review of recent evaluation studies from a number of countries indicates that considerable emphasis has been placed on the predictive validity criterion, as measured by the R2 statistic. However, the interpretation of the findings has been affected greatly by the methods used, especially the treatment and definition of outlier cases. Furthermore, the extent to which other evaluation criteria have been addressed has varied widely. In the absence of minimum evaluation standards, it is not possible to draw clear-cut conclusions about the superiority of one version of a casemix system over another, the need for a local adaptation, or the further development of an existing version. Without the evidence provided by properly designed studies, policy-makers and managers may place undue reliance on subjective judgments and the views of the most influential, but not necessarily best informed, healthcare interest groups.

  6. Legal Issues Related to Donation of Organs, Tissues and Cells of Human Origin

    Full Text Available Scientific developments, positive changes in attitude of the man and the new legal framework allow the donation of organs, tissues and cells of human origin. In this context it is necessary to clarifywhether the donation covered by the special law is, legally, one and the same as that covered by the Romanian Civil Code in force and qualified the successor’s right to accept or reject late withdrawals for transplantation. The right to life and physical integrity is personal patrimony; it is a subjective civil right that has no economic content and it cannot be measured in money. Consequently, the content of these rights can not be expressed in money, the property does not belong to their owner. Given the above view, "the right of disposal" to donation of organs, tissues and cells of human origin is an attribute of ownership, right to life and physical integrity, as a personal right that is an intimate attribute patrimonial related to the person’s right to dispose of his body as it wishes, within the law. Addressing these issues it is necessary to clarify the legal consequences of donating organs, tissues and cells of human origin, considering that medical activities are becoming more numerous.

    The monitoring of pancreas-related health issues in real-time and outside the medical room is a challenge in the wide e-health domain. This paper introduces WHEAMO, a novel e-health platform which employs medical implants (biosensors), which function as antennas, planted in the pancreas. WHEAMO uses wireless in-body propagation to track, monitor, and record critical parameters, such as glucose. The signal reaches the skin and then it is propagated in an indoor environment (e.g., medical room) over to a terminal equipped with adaptive, user-configurable, and intelligent mechanisms which provide personalized recommendations to varying WHEAMO users (e.g., medical personnel, health care workers, patients). The personalized nature of the provided recommendations is based on patients unique characteristics via a sophisticated knowledge-base. The fundamentals of in-body and on-body wireless propagation and channel characterization have been studied in a series of published works. Researchers have tested both electric-field (dipole) and magnetic-field (patch, loop) antennas. Another important aspect concerns the frequency band in which the signal propagation will occur. Among the frequencies that have gathered scientific and academic interest are the Medical Implant Communication Service (MICS) band at 402-405 MHz, the 900 MHz channel and the industrial, scientific and medical (ISM) radio band at 2.45 GHz.

    Children with disorders of sex development (DSD) manifest at birth with malformed genitalia or later with atypical pubertal development. Those born with malformed genitalia are often diagnosed at birth. However, in resource-poor countries like India, where not all births are supervised by healthcare workers, some of these children remain undiagnosed until puberty or even later. The aim of this study was to assess the gender issues and psychosocial problems of children with DSD. Participants included 205 children with DSD (103 with 46,XX DSD and 102 with 46,XY DSD). Both the children with DSD and their parents underwent semistructured interviews by a clinical psychologist. The birth of a child with DSD was perceived as a major medical and social problem by parents from all socioeconomic strata. Mothers were distressed as many believed the DSD condition was transmitted through the mother. Children who were not diagnosed and treated during infancy or early childhood experienced considerable social discrimination not only from relatives and friends but also from medical and paramedical staff in hospitals. Several patients had been operated during infancy without an etiological diagnosis and without provision of adequate information to the parents. Some children had problems related to complications of surgery. Most teenage patients with 5α-reductase-2 deficiency reared as females presented with gender dysphoria, while children with androgen insensitivity (except for one) or with gonadal dysgenesis developed a gender identity concordant with their gender of rearing. Parents of children with DSD preferred a male gender assignment for their children (if that was possible) because of the social advantages of growing up male in a patriarchal society.

    Genetically Modified Organisms (GMOs) are a fact of modern agriculture and a major field of discussion in biotechnology. As science incessantly achieves innovative and unexpected breakthroughs, new medical, political, ethical and religious debates arise over the production and consumption of transgenic organisms. Despite no described medical condition being directly associated with a diet including approved GM crops in large exposed populations such as 300,000,000 Americans and a billion Chinese, public opinion seems to look at this new technology with either growing concern or even disapproval. It is generally recognized that a high level of vigilance is necessary and highly desirable, but it should also be considered that GMOs are a promising new challenge for the III Millennium societies, with remarkable impact on many disciplines and fields related to biotechnology. To acquire a basic knowledge on GMO production, GM-food consumption, GMO interaction with humans and environment is of primary importance for risk assessment. It requires availability of clear data and results from rigorous experiments. This review will focus on public health risks related with a GMO-containing diet. The objective is to summarize state of the art research, provide fundamental technical information, point out problems and perspectives, and make available essential tools for further research. Are GMO based industries and GMO-derived foods safe to human health? Can we consider both social, ethical and public health issues by means of a constant and effective monitoring of the food chain and by a clear, informative labeling of the products? Which are the so far characterized or alleged hazards of GMOs? And, most importantly, are these hazards actual, potential or merely contrived? Several questions remain open; answers and solutions belong to science, to politics and to the personal opinion of each social subject.

  10. Steam generator thermal hydraulic design & functional architecture features and related operational and reliability issues requiring consideration

    Proper thermal hydraulic design and functional architecture are critical to successful steam generator operation and long term reliability. The evolution of steam generators has been a gradual learning process that has benefited from continuous industry operational experience (OPEX). Inadequate thermal hydraulic design can lead to numerous degradation mechanisms such as excessive deposition, corrosion, flow and level instabilities, fluid-elastic instabilities and tube wear. The functional architecture determines the health of the tube bundle and the other internals during manufacturing, handling and operation. It also determines thermal performance as well as establishing global thermal-hydraulic characteristics such as water level shrink and swell response. This paper discusses the range of operational and reliability issues and relates them to the thermal hydraulic attributes and functional architecture of steam generators (many SG reliability issues are further discussed in other presentations at this conference). In pursuing such issues, the paper focuses on the four major features of the equipment, identifying in each case the goals and requirements such features must meet. Typical approaches and the means by which such requirements are addressed in current equipment are discussed. The four features are: 1. Tubing Material and Tube Bundle Heat Transfer Performance; a. Two materials are in current use – Alloy 690 TT and Alloy 800. Both are good materials with excellent performance records which serve their owners very well (the reliability attributes of Alloy 800 and 690 are discussed in other papers at this conference). Caution is advised in the supply of any material: – material quality is only assured by what is specified to material suppliers in procurement specifications – i.e. - all the knowledge and research in the world assures nothing if its findings are not reflected in procurement requirements. b.

    For older adults, approaching end-of-life (EOL) brings unique transitions related to family relationships. Unfortunately, most families greatly underestimate the need to discuss these difficult issues. For example, parents approaching EOL issues often struggle with receiving assistance from others, avoiding family conflict, and maintaining their sense of personhood. In addition, discussions of EOL issues force family members to face their parents' mortality, which can be particularly difficult for adult children to process emotionally. This study explored aging issues identified by aging parents and their families as they traverse these impending EOL changes. Ten focus groups of seniors ( n = 65) were conducted. Focus groups were organized according to race (African-American/European-American), gender, and whether the older adult was living independently or in an assisted care facility. When asked open-ended questions about discussing aging and EOL issues with family members, participants revealed tensions that led us to consider Relational Dialectics Theory as a framework for analysis. The predominant tension highlighted in this report was certainty versus uncertainty, with the two sub-themes of sustained life versus sustained personhood and confronting versus avoiding EOL issues. For these data, there were more similarities than differences as a result of gender, race, or living situation than one might expect, although culture and financial status were found to be influential in the avoidance of EOL discussions. The results of this study help to provide additional insight into relational dialectics related to aging, EOL, and the importance of communication in facilitating family coping.

    2013-01-01

    Full Text Available Background: Environmentally acquired asbestos-related diseases (ARDs are of concern globally. In South Africa, there is widespread contamination of the environment due to historical asbestos mining operations that were poorly regulated. Although the law makes provision for the compensation of occupationally acquired ARDs, compensation for environmentally acquired ARDs is only available through the Asbestos Relief Trust (ART and Kgalagadi Relief Trust, both of which are administered by the ART. This study assessed ARDs and compensation outcomes of environmental claims submitted to the Trusts. Methods: The personal details, medical diagnoses, and exposure information of all environmental claims considered by the Trusts from their inception in 2003 to April 2010 were used to calculate the numbers and proportions of ARDs and compensation awards. Results: There were 146 environmental claimants of whom 35 (23.9% had fibrotic pleural disease, 1 (0.7% had lung cancer, and 77 (52.7% had malignant mesothelioma. 53 (36.3% claimants were compensated: 20 with fibrotic pleural disease and 33 with mesothelioma. Of the 93 (63.7% claimants who were not compensated, 33 had no ARDs, 18 had fibrotic pleural disease, 1 had lung cancer, and 44 had mesothelioma. In addition to having ARDs, those that were compensated had qualifying domestic (33; 62.2% or neighbourhood (20; 37.8% exposures to asbestos. Most of the claimants who were not compensated had ARDs but their exposures did not meet the Trusts’ exposure criteria. Conclusions: This study demonstrates the environmental impact of asbestos mining on the burden of ARDs. Mesothelioma was the most common disease diagnosed, but most cases were not compensated. This highlights that there is little redress for individuals with environmentally acquired ARDs in South Africa. To stop this ARD epidemic, there is a need for the rehabilitation of abandoned asbestos mines and the environment. These issues may not be unique to

  16. Invariance of molecular charge transport upon changes of extended molecule size and several related issues

    Full Text Available As a sanity test for the theoretical method employed, studies on (steady-state charge transport through molecular devices usually confine themselves to check whether the method in question satisfies the charge conservation. Another important test of the theory’s correctness is to check that the computed current does not depend on the choice of the central region (also referred to as the “extended molecule”. This work addresses this issue and demonstrates that the relevant transport and transport-related properties are indeed invariant upon changing the size of the extended molecule, when the embedded molecule can be described within a general single-particle picture (namely, a second-quantized Hamiltonian bilinear in the creation and annihilation operators. It is also demonstrates that the invariance of nonequilibrium properties is exhibited by the exact results but not by those computed approximately within ubiquitous wide- and flat-band limits (WBL and FBL, respectively. To exemplify the limitations of the latter, the phenomenon of negative differential resistance (NDR is considered. It is shown that the exactly computed current may exhibit a substantial NDR, while the NDR effect is absent or drastically suppressed within the WBL and FBL approximations. The analysis done in conjunction with the WBLs and FBLs reveals why general studies on nonequilibrium properties require a more elaborate theoretical than studies on linear response properties (e.g., ohmic conductance and thermopower at zero temperature. Furthermore, examples are presented that demonstrate that treating parts of electrodes adjacent to the embedded molecule and the remaining semi-infinite electrodes at different levels of theory (which is exactly what most NEGF-DFT approaches do is a procedure that yields spurious structures in nonlinear ranges of current–voltage curves.

    India is poorly placed in terms of world energy resources, while 16% of world's population lives in India, only 6% of coal and 0.6% of oil and gas reserves exist in the country. Moreover, the distribution of primary commercial energy resources is quite skewed. However, India is endowed with vast reserves of thorium. The energy potential of our modest uranium resources and sizeable thorium resources has been estimated to be six times that of our total coal reserves. Though during last fifty years since independence, India has made tremendous progress in the energy sector where the use of commercial energy has increased by ten folds. Electricity used during the same period has increased by eighty times. In spite of such an impressive growth the country, due to population growth, finds itself in the almost lowest bracket with regard to per capita consumption which is many fold lower than the world average. India as of today is a net energy importing country. The demand for energy, in particular electricity that has established to be the most efficient and convenient source, is projected to grow at 7-8% per annum for coming two decades. In such a demand scenario it is imperative that all the resources of energy must be judiciously utilised. However, with the depletion of fossil fuels and resulting possible price shocks a long-term energy security is required for the country. The paper deals with the role nuclear power can play in meeting the country's short term and long term demands, progress made and related issues. (author)

  18. A Qualitative Study of Service Provision for Alcohol Related Health Issues in Mid to Later Life.

    Catherine Haighton

    Full Text Available Epidemiological surveys over the last 20 years show a steady increase in the amount of alcohol consumed by older age groups. Physiological changes and an increased likelihood of health problems and medication use make older people more likely than younger age groups to suffer negative consequences of alcohol consumption, often at lower levels. However, health services targeting excessive drinking tend to be aimed at younger age groups. The aim of this study was to gain an in-depth understanding of experiences of, and attitudes towards, support for alcohol related health issues in people aged 50 and over.Qualitative interviews (n = 24, 12 male/12 female, ages 51-90 years and focus groups (n = 27, 6 male/21 female, ages 50-95 years were carried out with a purposive sample of participants who consumed alcohol or had been dependent.Participants' alcohol misuse was often covert, isolated and carefully regulated. Participants tended to look first to their General Practitioner for help with alcohol. Detoxification courses had been found effective for dependent participants but only in the short term; rehabilitation facilities were appreciated but seen as difficult to access. Activities, informal groups and drop-in centres were endorsed. It was seen as difficult to secure treatment for alcohol and mental health problems together. Barriers to seeking help included functioning at a high level, concern about losing positive aspects of drinking, perceived stigma, service orientation to younger people, and fatalistic attitudes to help-seeking. Facilitators included concern about risk of fatal illness or pressure from significant people.Primary care professionals need training on improving the detection and treatment of alcohol problems among older people. There is also a compelling need to ensure that aftercare is in place to prevent relapse. Strong preferences were expressed for support to be provided by those who had experienced alcohol problems themselves.

    Yaqeen S Mezaal

    Full Text Available This paper presents new Wide Bandpass Filter (WBPF and Narrow Bandstop Filter (NBSF incorporating two microstrip resonators, each resonator is based on 2nd iteration of Hilbert fractal geometry. The type of filter as pass or reject band has been adjusted by coupling gap parameter (d between Hilbert resonators using a substrate with a dielectric constant of 10.8 and a thickness of 1.27 mm. Numerical simulation results as well as a parametric study of d parameter on filter type and frequency responses are presented and studied. WBPF has designed at resonant frequencies of 2 and 2.2 GHz with a bandwidth of 0.52 GHz, -28 dB return loss and -0.125 dB insertion loss while NBSF has designed for electrical specifications of 2.37 GHz center frequency, 20 MHz rejection bandwidth, -0.1873 dB return loss and 13.746 dB insertion loss. The proposed technique offers a new alternative to construct low-cost high-performance filter devices, suitable for a wide range of wireless communication systems.

    We present the design, fabrication, and characterization of a polarization-selective infrared bandpass filter based on a two-layer subwavelength metallic grating for use in polarimetric imaging. Gold nanowires were deposited via physical vapor deposition (PVD) onto a silicon surface relief grating that was patterned using electron beam lithography (EBL) and fabricated using standard silicon processing techniques. Optical characterization with a broad-spectrum tungsten halogen light source and a grating spectrometer showed normalized peak TM transmission of 53% with a full-width at half-maximum (FWHM) of 122 nm, which was consistent with rigorous coupled-wave analysis (RCWA) simulations. Simulation results suggested that device operation relied on suppression of the TM transmission caused by surface plasmon polariton (SPP) excitation at the gold-silicon interface and an increase in TM transmission caused by a Fabry-Perot (FP) resonance in the cavity between the gratings. TE rejection occurred at the initial air/gold interface. We also present simulation results of an improved design based on a two-dielectric grating where two different SPP resonances allowed us to improve the shape of the passband by suppressing the side lobes. This newer design resulted in improved side-band performance and increased peak TM transmission.

  2. Mode Coupling and Nonlinear Resonances of MEMS Arch Resonators for Bandpass Filters

    We experimentally demonstrate an exploitation of the nonlinear softening, hardening, and veering phenomena (near crossing), where the frequencies of two vibration modes get close to each other, to realize a bandpass filter of sharp roll off from the passband to the stopband. The concept is demonstrated based on an electrothermally tuned and electrostatically driven MEMS arch resonator operated in air. The in-plane resonator is fabricated from a silicon-on-insulator wafer with a deliberate curvature to form an arch shape. A DC current is applied through the resonator to induce heat and modulate its stiffness, and hence its resonance frequencies. We show that the first resonance frequency increases up to twice of the initial value while the third resonance frequency decreases until getting very close to the first resonance frequency. This leads to the phenomenon of veering, where both modes get coupled and exchange energy. We demonstrate that by driving both modes nonlinearly and electrostatically near the veering regime, such that the first and third modes exhibit softening and hardening behavior, respectively, sharp roll off from the passband to the stopband is achievable. We show a flat, wide, and tunable bandwidth and center frequency by controlling the electrothermal actuation voltage.

    It has been shown that a fundamental mode adiabatically launched into a multimode SOI waveguide with submicron grating offers well-defined flat-top bandpass filter characteristics in transmission. The transmitted spectral bandwidth is controlled by adjusting both waveguide and grating design parameters. The bandwidth is further narrowed down by cascading two gratings with detuned parameters. A semi-analytical model is used to analyze the filter characteristics (1500  nm≤λ≤1650  nm) of the device operating in transverse-electric polarization. The proposed devices were fabricated with an optimized set of design parameters in a SOI substrate with a device layer thickness of 250 nm. The pass bandwidth of waveguide devices integrated with single-stage gratings are measured to be ∼24  nm, whereas the device with two cascaded gratings with slightly detuned periods (ΔΛ=2  nm) exhibits a pass bandwidth down to ∼10  nm.

The involved balun structure is composed of two back-to-back quarter-wavelength (λ/4) asymmetrical coupled-line sections. Detailed design formulas based on the asymmetrical coupled-line theory are given to validate the feasibility of the balun. Besides, to obtain filtering performance simultaneously, the balun is then effectively integrated with a pair of triple mode resonators. To demonstrate the design concept of the balun BPF, a prototype operating at 2.4 GHz with the fractional bandwidth (FBW) of about 19.2 % is designed, fabricated, and measured. Results indicate that between the two balanced outputs, the amplitude imbalance is less than 0.3 dB and the phase difference is within 180°±5° inside the whole passband. Both simulated and experimental results are in good agreement.

    The glomerular filtration barrier is known as a 'size cutoff' slit, which retains nanoparticles or proteins larger than 6-8 nm in the body and rapidly excretes smaller ones through the kidneys. However, in the sub-nanometre size regime, we have found that this barrier behaves as an atomically precise 'bandpass' filter to significantly slow down renal clearance of few-atom gold nanoclusters (AuNCs) with the same surface ligands but different sizes (Au18, Au15 and Au10-11). Compared to Au25 (∼1.0 nm), just few-atom decreases in size result in four- to ninefold reductions in renal clearance efficiency in the early elimination stage, because the smaller AuNCs are more readily trapped by the glomerular glycocalyx than larger ones. This unique in vivo nano-bio interaction in the sub-nanometre regime also slows down the extravasation of sub-nanometre AuNCs from normal blood vessels and enhances their passive targeting to cancerous tissues through an enhanced permeability and retention effect. This discovery highlights the size precision in the body's response to nanoparticles and opens a new pathway to develop nanomedicines for many diseases associated with glycocalyx dysfunction.

    Fully integrated low insertion loss micromachined band-pass filters are designed and fabricated on the silicon substrate (ρ = 10–20 Ω cm, ε r = 11.9) for UHF applications. Filters are made of silver, which has the highest conductivity of all metals, to minimize the ohmic loss. A detailed analysis for realizing low insertion loss and high out-of-band rejection filters using elliptic magnitude characteristics is presented, and a comprehensive model to take into account inductive parasitics of the interconnects is developed. Temperature characteristics of the filters are measured and show stable performance. The presented filters are different from the previously reported lumped element filters in that all filters are fully integrated on silicon substrate and occupy a remarkably smaller die area. Two filters are fabricated using the silver micromachining technique with center frequencies at 1.05 and 1.35 GHz. The filters have a constant 3 dB bandwidth of 300 MHz (28.6% and 22.2%) and an insertion loss of 1.4–1.7 dB. The low insertion loss and CMOS compatibility make the presented filters suitable candidates for radio frequency integrated circuits

    An S band narrowband bandpass filter BAW with center frequency 2.460 GHz, bandwidth 41MHz, band insertion loss - 1.154 dB, the passband ripple 0.9 dB, the out of band rejection about -42.5dB@2.385 GHz; -45.5dB@2.506 GHz was designed for potential UAV measurement and control applications. According to the design specifications, the design is as follows: each FBAR's stack was designed in BAW filter by using Mason model. Each FBAR's shape was designed with the method of apodization electrode. The layout of BAW filter was designed. The acoustic-electromagnetic cosimulation model was built to validate the performance of the designed BAW filter. The presented design procedure is a common one, and there are two characteristics: 1) an A and EM co-simulation method is used for the final BAW filter performance validation in the design stage, thus ensures over-optimistic designs by the bare 1D Mason model are found and rejected in time; 2) An in-house developed auto-layout method is used to get compact BAW filter layout, which simplifies iterative error-and-try work here and output necessary in-plane geometry information to the A and EM cosimulation model.

    We present the first realisation of linear variable bandpass filters in nanoporous anodic alumina (NAA-LVBPFs) photonic crystal structures. NAA gradient-index filters (NAA-GIFs) are produced by sinusoidal pulse anodisation and used as photonic crystal platforms to generate NAA-LVBPFs. The anodisation period of NAA-GIFs is modified from 650 to 850 s to systematically tune the characteristic photonic stopband of these photonic crystals across the UV-visible-NIR spectrum. Then, the nanoporous structure of NAA-GIFs is gradually widened along the surface under controlled conditions by wet chemical etching using a dip coating approach aiming to create NAA-LVBPFs with finely engineered optical properties. We demonstrate that the characteristic photonic stopband and the iridescent interferometric colour displayed by these photonic crystals can be tuned with precision across the surface of NAA-LVBPFs by adjusting the fabrication and etching conditions. Here, we envisage for the first time the combination of the anodisation period and etching conditions as a cost-competitive, facile, and versatile nanofabrication approach that enables the generation of a broad range of unique LVBPFs covering the spectral regions. These photonic crystal structures open new opportunities for multiple applications, including adaptive optics, hyperspectral imaging, fluorescence diagnostics, spectroscopy, and sensing.

    In this paper, we present a design and measurements of a five-section bandpass filter with a passband from 96 to 106 GHz. The insertion loss is less than 1.4 dB in the passband, and the rejection is better than 40 dB in the range from 115 to 142 GHz. We use transmission line coupling theory based...... on Tchebyscheff’s synthesis in order to provide an initial guess for the geometrical parameters of the filter such as cavity lengths and coupling widths. The filter is manufactured from brass in two halves in the E-plane cut topology. The S-parameters of the filter are measured and compared with the simulations....... The measured passband insertion loss is approximately 0.4 dB worse than in the simulation, and the measured passband width is approximately 3.4% narrower. The measured filter attenuation roll-off corresponds well to the simulation. We also compare our S-parameter measurements of the E-plane filter...

    2003-01-01

    Segmented correlation is a useful technique for testing a superconducting analogue-to-digital converter, as it allows the output spectrum to be estimated with fine frequency resolution even when data record lengths are limited by small on-chip acquisition memories. Previously, we presented segmented correlation measurements on a superconducting bandpass delta-sigma modulator sampling at 40.2 GHz under idle channel (no input) conditions. This paper compares the modulator output spectra measured by segmented correlation with and without an input tone. Important practical considerations of calculating segmented correlations are discussed in detail. Resolution enhancement by segmented correlation does reduce the spectral width of the input tone in the desired manner, but the signal power due to the input increases the variance of the spectral estimate near the input frequency, hindering accurate calculation of the in-band noise. This increased variance, which is predicted by theory, must be considered carefully in the application of segmented correlation. Methods for obtaining more accurate estimates of the quantization noise spectrum which are closer to those measured with no input are described

    2008-02-01

    This paper presents a novel compact high temperature superconducting (HTS) bandpass filter (BPF) that employs a newly developed miniaturized coplanar-waveguide (CPW) quarter-wavelength resonators with strongly-coupled open stubs. The proposed resonator has a structure in which the open stubs are aligned close to the center conductor of the resonator. This is because strongly-coupled resonators have widely-split resonant frequencies, and the lowest resonant frequency is employed as the fundamental resonant frequency of the resonator in order to achieve miniaturization. The proposed resonator is 1.7 mm or less in length for use in the 5-GHz band, whereas the conventional straight resonator is approximately 6.4 mm long. A four-pole Chebyshev HTS BPF is designed and fabricated using the proposed CPW resonators. The entire length of the proposed four-pole filter is 15 mm. The frequency response of the fabricated filter agrees well with the electromagnetic simulation results. The proposed filter achieves a size reduction of at least 50% compared to previously reported filters without any degradation in the frequency characteristics.

    Simulations of forced homogeneous isotropic turbulence with resolutions of 128{sup 3} and 256{sup 3} using the Lattice Boltzmann method are carried out. The multi-scale vortical structures are identified using the band-pass Fourier cutoff filtering. Three fields at each simulation are extracted and their characteristics are studied. The vortical structures are visualized using the Q-identification method. A new lattice segmentation scheme to identify the central axes of the vortical structures is introduced. The central points of each vortex are identified and they are connected using the direction cosines technique. Results show that the Q-spectrum of the fine scale field survives at low and high wave-numbers. However, the large and intermediate Q-spectra survives till wave-numbers less than or equal to twice the used velocity cutoff wave-numbers. It is found that the extracted central axes clearly resemble the corresponding vortical structures at each scale. Using the central axes scheme, the radii and lengths of the vortical structures at each scale are determined and compared. It is also found that the radii of the identified vortical structures at each scale in both simulations are of the order of several times the Kolmogorov microscales.

  13. Investigation of New Microstrip Bandpass Filter Based on Patch Resonator with Geometrical Fractal Slot.

    Directory of Open Access Journals (Sweden)

    Yaqeen S Mezaal

    Full Text Available A compact dual-mode microstrip bandpass filter using geometrical slot is presented in this paper. The adopted geometrical slot is based on first iteration of Cantor square fractal curve. This filter has the benefits of possessing narrower and sharper frequency responses as compared to microstrip filters that use single mode resonators and traditional dual-mode square patch resonators. The filter has been modeled and demonstrated by Microwave Office EM simulator designed at a resonant frequency of 2 GHz using a substrate of εr = 10.8 and thickness of h = 1.27 mm. The output simulated results of the proposed filter exhibit 22 dB return loss, 0.1678 dB insertion loss and 12 MHz bandwidth in the passband region. In addition to the narrow band gained, miniaturization properties as well as weakened spurious frequency responses and blocked second harmonic frequency in out of band regions have been acquired. Filter parameters including insertion loss, return loss, bandwidth, coupling coefficient and external quality factor have been compared with different values of perturbation dimension (d. Also, a full comparative study of this filter as compared with traditional square patch filter has been considered.

    This paper incorporates an improved design of Ultra Wideband Bandpass filter by using split ring resonators (SRR) along with the coupled microstrip lines. The use of split ring resonators and shunt step impedance open circuit stub enhances the stability due to transmission zeroes at the ends. The designing of filter and simulation of parameters is carried out using Ansoft's HFSS 13.0 software on RT/Duroid 6002 as a substrate with dielectric constant of 2.94. The design utilizes a frequency band from 22GHz to 29GHz. This band is reserved for Automotive Radar system and sensors as per FCC specifications. The proposed design demonstrates insertion loss less than 0.6dB and return loss better than 12dB at mid frequency i.e. 24.4GHz. The reflection coefficient shows high stability of about 12.47dB at mid frequency. The fractional bandwidth of the proposed filter is about 28.7% and size of filter design is small due to thickness of 0.127mm.

    Phosphate glasses doped with copper ions having general composition 42P{sub 2}O{sub 5}–39ZnO–(18−x) Na{sub 2}O–1CaO–xCu{sub 2}O [x=2, 4, 6, 8, 10 mol%] were prepared using a conventional melt-quench technique. Physical and chemical properties of the glasses were investigated using X-ray diffraction technique and UV–visible optical absorption. The density was measured by Archimedes' method, and molar volume (V{sub M}) was calculated. It is found that density and molar volume show opposite trend by increasing Cu{sub 2}O content. Absorbance and transmittance at the normal incidence are measured by a spectrophotometer in the spectral range of 190–1100 nm. Analyses of the obtained results were considered in the frame of current theories. Absorption data were used for absorption coefficient, the optical band gap (E{sub opt}), the cutoff in UV and IR bands to the bandpass filter, which confirmed the optical properties of this type of filter. E{sub opt} values for different glass samples are found to decrease with increasing Cu{sub 2}O content.

    Reactor coolant pumps contain mechanical seals to limit the leakage of pressurized coolant from the reactor coolant system to the containment. These seals have the potential to leak, and a few have degraded and even failed resulting in a small break loss of coolant accident (LOCA). As a result, ''Reactor Coolant Pump Seal Failure,'' Generic Issue 23 was established. This report summarizes the findings of a technical investigation generated as part of the program to resolve this issue. These technical findings address the various fact-finding issue tasks developed for the action plan associated with the generic issue, namely background information on seal failure, evaluation of seal cooling, and mechanical- and maintenance-induced failure mechanisms. 46 refs., 15 figs., 14 tabs

    Walsh, Justin

    in space. The United Nations Outer Space Treaty of 1967 -the primary document governing how nations act in outer space -is now hopelessly out-of-date. There is no mention in the treaty of cultural heritage (the UNESCO convention that concerns international protection of cultural heritage on Earth was not completed until 1970), nor was there any recognition of the role private groups and individuals might play in space exploration. This paper will outline key legal and ethical issues related to cultural heritage management and protection. It will also suggest some ways in which culturally significant sites in space can be protected for future study and even touristic appreciation.

    Understanding the perception of patients on research ethics issues related to biobanking is important to enrich ethical discourse and help inform policy. We examined the views of leukemia patients undergoing treatment in clinics located in the Princess Margaret Hospital in Toronto, Ontario, Canada. An initial written survey was provided to 100 patients (64.1% response rate) followed by a follow-up survey (62.5% response rate) covering the topics of informed consent, withdrawal, anonymity, incidental findings and the return of results, ownership, and trust. The majority (59.6%) preferred one-time consent, 30.3% desired a tiered consent approach that provides multiple options, and 10.1% preferred re-consent for future research. When asked different questions on re-consent, most (58%) reported that re-consent was a waste of time and money, but 51.7% indicated they would feel respected and involved if asked to re-consent. The majority of patients (62.2%) stated they had a right to withdraw their consent, but many changed their mind in the follow-up survey explaining that they should not have the right to withdraw consent. Nearly all of the patients (98%) desired being informed of incidental health findings and explained that the information was useful. Of these, 67.3% of patients preferred that researchers inform them and their doctors of the results. The majority of patients (62.2%) stated that the research institution owns the samples whereas 19.4% stated that the participants owned their samples. Patients had a great deal of trust in doctors, hospitals and government-funded university researchers, moderate levels of trust for provincial governments and industry-funded university researchers, and low levels of trust towards industry and insurance companies. Many cancer patients surveyed preferred a one-time consent although others desired some form of control. The majority of participants wanted a continuing right to withdraw consent and nearly all wanted to be

    2015-01-01

    A 2014 external review of medical schools in Israel identified several issues of importance to the nation's health. This paper focuses on three inter-related policy-relevant topics: planning the physician and healthcare workforce to meet the needs of Israel's population in the 21(st) century; enhancing the coordination and efficiency of medical education across the continuum of education and training; and the financing of medical education. All three involve both education and health care delivery. The physician workforce is aging and will need to be replenished. Several physician specialties have been in short supply, and some are being addressed through incentive programs. Israel's needs for primary care clinicians are increasing due to growth and aging of the population and to the increasing prevalence of chronic conditions at all ages. Attention to the structure and content of both undergraduate and graduate medical education and to aligning incentives will be required to address current and projected workforce shortage areas. Effective workforce planning depends upon data that can inform the development of appropriate policies and on recognition of the time lag between developing such policies and seeing the results of their implementation. The preclinical and clinical phases of Israeli undergraduate medical education (medical school), the mandatory rotating internship (stáge), and graduate medical education (residency) are conducted as separate "silos" and not well coordinated. The content of basic science education should be relevant to clinical medicine and research. It should stimulate inquiry, scholarship, and lifelong learning. Clinical exposures should begin early and be as hands-on as possible. Medical students and residents should acquire specific competencies. With an increasing shift of medical care from hospitals to ambulatory settings, development of ambulatory teachers and learning environments is increasingly important. Objectives such as these

  3. A Method against Interrupted-Sampling Repeater Jamming Based on Energy Function Detection and Band-Pass Filtering

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Interrupted-sampling repeater jamming (ISRJ is a new kind of coherent jamming to the large time-bandwidth linear frequency modulation (LFM signal. Many jamming modes, such as lifelike multiple false targets and dense false targets, can be made through setting up different parameters. According to the “storage-repeater-storage-repeater” characteristics of the ISRJ and the differences in the time-frequency-energy domain between the ISRJ signal and the target echo signal, one new method based on the energy function detection and band-pass filtering is proposed to suppress the ISRJ. The methods mainly consist of two parts: extracting the signal segments without ISRJ and constructing band-pass filtering function with low sidelobe. The simulation results show that the method is effective in the ISRJ with different parameters.

    Indonesia being a member of ASEAN belongs to the group of developing country. If Indonesia decides to embark on the establishment of nuclear power plan then the country will have no choice but to discuss the following issues: Safe operation of the plant and management of the nuclear waste. Safe operation of the power plant is important not only from the point of view of hazards to human being, or economic loss, or even death, but equally important it is also from the psychological point of view in that not to loose the society's confidence in the overall nuclear power plant programme in the future. The issue of safe operation involves both a safely designed system as well as skilled personnels to execute a well designed operation procedure. The issue of nuclear safety is getting more and more attention lately for various, some due to a deep concern about the quality of the inherent safety of the nuclear power plant to be built, others may just use their emotion to ask question like ''what its''. The issue of nuclear waste is as fundamental as the plant safety. Common people make very little difference between an atomic bomb and waste from a nuclear power plant. Another issue is one of transfer of technology which needs to be tied up with the overall industrialization process, meaning that embarking on nuclear power programme needs to contribute to local industrial activities, at least for some parts or components which can be manufactured locally.

    An expanding elderly population poses challenges for the provision of care and treatment for age-related physical and mental disorders. Cognitive impairment (CI)/dementia is one such mental disorder that is on the rise in Singapore and has concomitant implications for social and health systems. The objective of this study is to understand the perspectives of prominent stakeholders about current and future issues and challenges associated with CI/dementia among the elderly in Singapore. Using indepth interviews, this qualitative study obtained the views of multiple stakeholders on issues and challenges associated with CI/dementia in Singapore. The 30 individuals interviewed as part of the study included clinicians, policy-makers, researchers, community workers, administrators, and caregivers. Using a framework approach, interview texts were indexed into domains and issues by utilizing NVivo 9.0 software. The stakeholders expressed concerns related to multiple domains of the CI/dementia care system: attitude and awareness, economics, education, family caregiving, inputs to care system, living arrangements, prevention, screening and diagnosis, and treatment and management of care. Within each domain, multiple issues and challenges were identified by respondents. The study identifies a complex set of inter-related issues and challenges that are associated with the care and treatment of people with CI/dementia. The results suggest that CI and dementia profoundly affect patients, families, and communities and that the issues related to the two disorders are truly system-wide. These findings lay the foundation for utilization of a systems approach to studying CI/dementia and provide an analytic framework for future research on complex health care issues.

    International Nuclear Information System (INIS)

    Okrent, D.

    1993-01-01

    This paper asks whether some of the fundamental bases for the 1985 USEPA standard on disposal of high level radioactive wastes (40 CFR Part 191) warrant re-examination. Similar questions also apply to the bases for the radioactive waste disposal requirements proposed by most other countries. It is suggested that the issue of intergenerational equity has been dealt with from too narrow a perspective. Not only should radioactive and nonradioactive hazardous waste disposal be regulated from a consistent philosophic basis, but the regulation of waste disposal itself should be embedded in the broader issues of intergenerational conservation of options, conservation of quality, and conservation of access.

    The author discusses some noticeable issues in drafting assessment report of nuclear and radiation environmental impacts and relevant aspects needed to be considered from the point of view of comprehensive environmental assessment. The considerable issue are principles of radioactive waste management, optimization of radiation protection and collective dose, and uncertainty of the assessment. Implementing reporting system on assessment of nuclear and radiation environmental impacts would improve environmental protection for nuclear and radiation facilities. However, trade's, regional , country and global assessment of environmental impacts has to be enhanced. For this purpose, it is necessary to develop methodology of qualitative and quantitative comprehensive assessment

    Even though health inequalities are conditioned by many aspects of the environment, much of the existing research focuses on the social environment. This emphasis has the effect to neglect other environmental aspects such as its physical dimension. The physical environment, which is linked to housing conditions, may contribute to the uneven distribution of health. In this study, we examined 19 housing-related issues among a representative sample of 2,000 adults residing in a Quebec (Canada) health region characterized by a mix of rural, semi-rural, and urban areas. The distribution of these issues was examined according to socioeconomic and geographic indicators of social position. Summary measures of inequalities were assessed. Our results showed that the prevalence of nearly all housing-related issues was higher among low-income households compared to more affluent ones. Highly educated individuals showed better housing conditions, whereas different issues tended to cluster in deprived or densely populated areas. To conclude, we observed steep gradients between social class and poor housing conditions. This may explain a substantial part of health inequality on the regional scale. The surveillance of housing-related issues is therefore essential to properly inform and mobilize local stakeholders and to develop interventions that target vulnerable groups on this level.

    In recent years, greenhouse automatic-control, based on the measurement of solar irradiance, has been attracting attention. This control is an effective method for improving crop production. In the agricultural field, it is necessary to measure Photon Flux Density (PFD), which is an important parameter in the promotion of plant growth. In particular, the PFD of Photosynthetically Active Radiation (PAR, 400-700 nm) and Plant Biologically Active Radiation (PBAR, 300-800 nm) have been discussed in agricultural plant science. The commercial quantum meter (QM, PAR meter) can only measure Photosynthetically Photon Flux Density (PPFD) which is the integrated PFD quantity on the PAR wavelength. In this research, a band-spectral pyranometer or quantum meter using PVs with optical bandpass filters for dividing the PBAR wavelength into 100 nm bands (five independent channels) was developed. Before field testing, calibration of the instruments was carried out using a solar simulator. Next, a field test was conducted in three differing weather conditions such as clear, partly cloudy and cloudy skies. As a result, it was found that the response rate of the developed pyranometer was faster by four seconds compared with the response rate of the commercial pyranometer. Moreover, the outputs of each channel in the developed pyranometer were very similar to the integrated outputs of the commercial spectroradiometer. It was confirmed that the solar irradiance could be measured in each band separately using the developed band-spectral pyranometer. It was indicated that the developed band-spectral pyranometer could also be used as a PV band-spectral quantum meter which is obtained by converting the band irradiance into band PFD.

    Full Text Available Background. Randomised controlled trials (RCTs investigating Complementary and Alternative Medicine (CAM for pregnancy-related issues have encountered issues with recruitment and attrition. Little is known about the cause of these issues. Methods. Data was gathered from an antenatal CAM randomised controlled trial. During foetal anomaly appointments, women meeting inclusion criteria were invited to participate in the trial. Numbers of women invited and eligible were recorded. Reasons for noninterest were noted and analysed. Focus groups exploring trial experience of participants were also conducted. Findings. Of the 428 women invited to participate, 376 were eligible and just under a quarter participated. Reasons for nonparticipation included concerns about CAM and lack of interest in participation in research. Other factors negatively affecting recruitment included recruitment timing, competition for participants, limited support from staff, and inadequate trial promotion. Factors encouraging recruitment included being interested in research and seeking pain relief. Reasons for dropping out were time constraints, travel issues, work commitments, and pregnancy issues. Several women in the sham and usual care group dropped out due to dissatisfaction with treatment allocation. Conclusion. CAM researchers must explore problems encountered with recruitment and attrition so that evidence-based implementation strategies to address the issues can be developed.

    The solid waste form 'spent fuel' constitutes both the dominant radionuclide source as well as a first radionuclide retention barrier of a planned future high level nuclear waste isolation systems in deep granite formations. In order to evaluate the performance of spent fuel as part of the multibarrier containment system in a deep repository, the radionuclide release properties in groundwater must be predicted over very long time periods. Radionuclide release is not an inherent materials property of the fuel but depends, besides fuel specific parameters, mainly on time but as well on the geochemical and hydraulic environment of the disposal location. The study SR 97 documents the large effort of SKB to assess the long-term performance of a repository containing spent nuclear fuel. Scenario and consequence analyses are clearly described, considering major physical and chemical interactions of the various components of the multi-barrier isolation system. The approach attempts to assess both a realistic and a pessimistic evolution scenario. The present report attempts to evaluate whether this approach is thoroughly carried through to assess the performance of spent nuclear fuel in a repository. Main issues are radionuclide inventories and inventory distribution between structural parts of the fuel assembly and the fuel matrix, potential fuel alteration prior to water access, as well as models for fuel matrix dissolution and instant release fractions. Uncertainties in radionuclide inventories are discussed and were found for many radionuclides to be higher than assumed in SR 97. This is particularly true for Cl-36. This nuclide is a potential key biosphere dose contributor in various international safety assessments. Of particular importance are uncertainties related to the partition of radionuclides between metallic parts of the fuel assembly and the fuel matrix, since inventories of metallic parts are considered to be released instantaneously.

    2008-01-01

    Increasing use of preimplantation genetic diagnosis (PGD) poses numerous clinical, social, psychological, ethical, legal and policy dilemmas, many of which have received little attention. Patients and providers are now considering and using PGD for a widening array of genetic disorders, and patients may increasingly seek 'designer babies.' In the USA, although governmental oversight policies have been discussed, few specific guidelines exist. Hence, increasingly, patients and providers will face challenging ethical and policy questions of when and for whom to use PGD, and how it should be financed. These issues should be better clarified and addressed through collection of data concerning the current use of PGD in the USA, including factors involved in decision making about PGD use, as well as the education of the various communities that are, and should be, involved in its implementation. Improved understanding of these issues will ultimately enhance the development and implementation of future clinical guidelines and policies.

    Current educational curriculum will be more improved and the materials in schools will be somewhat different by the year of 2002 when students have two days off in a week. It is a well known fact that recent Japanese people's level of understanding about Science and Technology is the second from the bottom among OECD nations and, as a matter of fact, few schools are dealing with scientific issues such as atomic energy or radiation. High school teachers need to survey what students know about atomic power and radiation, how deep they studied in previous schools and what kind of interest they have in conservation of world energy sources or environmental issues discussed today. Through questionnaires to 328 students, it became clear that they were most interesting to the effect of radiation or radioactivity on any kind of things in the environment, and that they want to know solutions for those problems such as greenhouse effect, ozone layers and Garbage disposal.

    1996-06-01

    Environmental health and environmental quality issues along the U.S.-Mexico border have been of concern for several years. The enactment of the North American Free Trade Agreement and the presence of the maquiladoras (foreign-owned industries using imported raw materials) have intensified those concerns recently. Efforts to assess these issues are complicated by the fact that many of the issues affecting the border region are within federal jurisdiction, but the problems are regional and local in nature. Thus, state and local governments become involved with public concerns about real and potential problems. One major problem is that environmental health data from this region are lacking, particularly from Mexico. Some new agencies such as the Border Environment Cooperation Commission, the United States-Mexico Border Health Commission, and the North American Commission on Environmental Cooperation have joined several existing agencies at the federal and state level to address environmental quality and health. Several studies have been initiated to determine air and water quality, but little is being done in the areas of hazardous waste and health assessment. Several problems are anticipated in the generation of such data, such as its format and accessibility. Data gaps and research needs are discussed.

    Highlights: • IHS affects only the PHTS and the BoP (Balance of Plant). • PIEs list does not change but IHS influences PIEs evolution. • Additional issues to be addressed in PIEs study due to the implementation of HIS. • No safety/operational major obstacles were found for IHS concept. - Abstract: The functional deviations able to compromise system safety in the EU DEMO Primary Heat Transfer System (PHTS) with intermediate heat storage (IHS) based on molten salts are identified and compared to the deviations identified with PHTS without IHS. The resulting safety issues for the Balance of Plant (BoP) have been taken into account. Functional Failure Mode and Effects Analysis (FFMEA) is used to highlight the Postulated Initiating Events (PIE) of incident/accident sequences and to provide some safety insights during the preliminary design. The architecture of the system with IHS does not introduce new PIE with respect to the case without IHS, but it modifies some of them. In particular the two Postulated Initiating Events that are affected by the presence of IHS are the LOCA in the tubes of the HX between primary and intermediate circuit and the loss of heat sink for the first wall or the breeding zone. In fact the IHS introduces some advantages concerning the stability of the secondary circuit, but some weaknesses are associated to the physical-chemical nature of molten salts, especially oxidizing power, corrosive nature and risk of solidification. These issues can be managed in the design by the introduction of new safety functions.

    1997-01-01

    The concepts of exclusion, exemption and clearance have been established in international recommendations and, standards for radiation protection and the management of radioactive waste in recent years. The consistent application of these concepts has given rise to various problems in different spheres of use. This is particularly the case in the mining and minerals processing industries dealing with materials exhibiting elevated concentrations of naturally occurring radionuclides. This paper takes the South African mining industry as an example and highlights some of the issues that have arisen in applying these concepts within a regulatory control regime. (author)

    The treatment of gas-related issues for repositories located in rock salt by GRS and ISTec has followed a strategy which has been developed with increasing complexity and degree of detail in the past. The strategy today clearly indicates the direction to establish a comprehensive safety case and the work that remains to be done. For gas generation mainly long-term aspects are an issue to increase accuracy of predictions. Physical modelling especially for HLW is still incomplete with regard to the coupling of fluid flow with geomechanics, solution/precipitation effects and geochemistry. The appropriate tools to transform the physical models into numerical solutions are at hand in principle but have to be further developed collaterally to the physical modelling. The first full-scale demonstration of safety regarding gas issues in rock salt will have to be provided for the licensing of the Morsleben repository shut-down in the near future. (authors)

    Full Text Available Abstract Background Measures to address gender-specific health issues are essential due to fundamental, biological differences between the sexes. Studies have increasingly stressed the importance of customizing approaches directed at women’s health issues according to stages in the female life cycle. In Korea, however, gender-specific studies on issues affecting Korean women in relation to stages in their life cycle are lacking. Accordingly, the Korean Study of Women’s Health-Related Issues (K-Stori was designed to investigate life cycle-specific health issues among women, covering health status, awareness, and risk perceptions. Methods K-Stori was conducted as a nationwide cross-sectional survey targeting Korean women aged 14–79 years. Per each stage in the female life cycle (adolescence, childbearing age, pregnancy & postpartum, menopause, and older adult stage, 3000 women (total 15,000 were recruited by stratified multistage random sampling for geographic area based on the 2010 Resident Registration Population in Korea. Specialized questionnaires per each stage (total of five were developed in consultation with multidisciplinary experts and by reflecting upon current interests into health among the general population of women in Korea. This survey was conducted from April 1 to June 31, 2016, at which time investigators from a professional research agency went door-to-door to recruit residents and conducted in-person interviews. Discussion The study’s findings may help with elucidating health issues and unmet needs specific to each stage in the life cycle of Korean women that have yet to be identified in present surveys.

    The Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP3) will be held in Kyoto in December 1997. Described herein are the current status and issues of the convention. USA and Japan, which hold important keys to set up the abatement target, have issued no proposals concretely at the current AGBM (Ad-hoc Group Berlin Mandate) 7, and the conference for the concrete targets will be decided in the next AGBM 8 to be held in October. The final target will be set by the ministerial segment of COP3, because the negotiations for the treaty are political in nature. USA proposes reduction at a uniform, realistic rate, and Japan proposes reduction at a uniform rate or setting up the emission target per capita, each being different from reduction at a much higher uniform rate proposed by EU. Within EU, however, 10% out of 15% reduction rate it proposes is agreed by the member countries, and the remaining rate of % may not be agreed. It is necessary for the advanced parties to set up realistic and legally binding solutions, including ratification by USA, which can persuade the developing countries. tab.1

    Current educational curriculum will be more improved and the materials in schools will be somewhat different by the year of 2002 when students have two days off in a week. It is a well known fact that recent Japanese people's level of understanding about Science and Technology is the second from the bottom among OECD nations and, as a matter of fact, few schools are dealing with scientific issues such as atomic energy or radiation. High school teachers need to survey what students know about atomic power and radiation, how deep they studied in previous schools and what kind of interest they have in conservation of world energy sources or environmental issues discussed today. Through questionnaires to 328 students, it became clear that they were most interesting to the effect of radiation or radioactivity on any kind of things in the environment, and that they want to know solutions for those problems such as greenhouse effect, ozone layers and Garbage disposal.

    Full text: Assessment of risk due to hydrogen released during postulated hypothetical accident scenarios in the nuclear power plants (NPPs) has been an important area of R and D studies world over. The issues, such as appropriate methodologies for estimation of hydrogen source term and for hydrogen dispersion calculations, technology development for hydrogen mitigation in containment of NPPs and assessment of damage due to deflagration/detonation of hydrogen (if it occurs) are being addressed as a part of some of the multidisciplinary study programs currently underway in BARC. While a significant overall progress has been achieved in general as a result of these programs, requirements of further fine-tuning of these studies have also emerged. The present paper takes a brief look at the current state-of the-art technology available to address these issues. The progress of R and D studies underway at BARC has also been critically reviewed in the paper to bring out necessary planning of further studies so as to enhance the safety of Indian NPPs

    Background The limited integration of ethics in nutrition-related public health policies and interventions is one major concern for those who have the task of implementing them. Ethical challenges that are overlooked during the development of such interventions could raise serious ethical issues during their implementation and even after. As a result, these decision makers need technical support and ethical guidance for adaptation of interventions to local (cultural, social, economic, etc.) contexts. Aim The goal of this scoping review is to delineate and “map” the range of ethical issues in nutrition-related public health interventions, as well as the range of the various fields in which they may arise. Methods A scoping review of empirical research and conceptual literature was conducted following the framework of Arksey and O’Malley. Searches using PubMed with Medical Subject Headings (MeSH) categories and Advanced Search Builder as well as in the Global Health Library were performed. The final sample consists of 169 publications. Results The ethics of public health prevention or treatment of obesity and non-communicable diseases is the most explicitly and frequently discussed subject. In comparison, ethical issues raised by public health interventions in the fields of undernutrition, breastfeeding, vitamin/mineral supplementation and food fortification, food security, food sustainability and food safety are addressed in a lower proportion of the sample.

    Full Text Available This study investigated attitudes in the Thai construction industry sector towards 21 issues related to “delay in the approval of submittals” that may initiate conflicts among various parties. Knowledge gained from this study can be applied to the analyses of the completeness and appropriateness of contract conditions and to improve contract drafting. The attitudes of the majority of people in the industry towards several issues related to the time frame for the approval of submittals, compensation for cost increases and profit losses, and time frames for notifications of delayed approval and claim submission were found to be inconsistent with existing conditions in standard contracts. Various issues that are not covered in the standard contract forms, such as the time frame for providing reminders and the types of time loss and direct costs that can be claimed, were also found to have high tendencies to initiate conflicts between contracting parties. Finally, we also found that the organisational affiliation of the respondents (i.e., employer or contractor influenced their attitudes towards some, but not all, contractual issues.

    The large area was polluted by the radioactive fallout released after the nuclear fuel meltdown of Fukushima first nuclear plant of Tokyo electric power company. The news media that reported the accident were required to have scientific knowledge on the structure of the nuclear reactor and the physics and health issues of the radioactivity. In this paper, we focus on how the weekly magazines reported this critical accident. The weekly magazines are not regarded as a neutral news media. Rather, their articles in general strongly reflect the editorial opinions. In this sense, the weekly magazines are 'biased media'. So, there are many points to discuss from the view point of the science communication. We analyze the articles appeared in the seven major weekly magazines published during the first half year after the earthquake. We found that the differences in the scientific literacy between magazines are reflected, for example, in selection of the experts who made comments in articles. (author)

    We study the implications of adopting hyperbolic-driver coordinate conditions motivated by geometrical considerations. In particular, conditions that minimize the rate of change of the metric variables. We analyze the properties of the resulting system of equations and their effect when implementing excision techniques. We find that commonly used coordinate conditions lead to a characteristic structure at the excision surface where some modes are not of outflow type with respect to any excision boundary chosen inside the horizon. Thus, boundary conditions are required for these modes. Unfortunately, the specification of these conditions is a delicate issue as the outflow modes involve both gauge and main variables. As an alternative to these driver equations, we examine conditions derived from extremizing a scalar constructed from Killing's equation and present specific numerical examples

    Radiation therapy (RT) is an essential and cost-effective cancer treatment, but it is underutilized in Australia. We aimed to quantify consumers' perceptions of factors that influence RT decisions. A cross-sectional, survey-based study was conducted in March-August 2012. Potential participants were invited to complete an electronic survey disseminated through multiple patient support and advocacy groups throughout New South Wales (NSW), Australia. Study invitations were also placed in local newspapers across NSW with hard copy surveys mailed to respondents. Current or past cancer patients (and carers) who had been offered RT were eligible to participate regardless of their RT decision. Of the 1191 participants (electronic, n = 1153; hard copy, n = 38), 91% were female, most (88%) were current or past patients, and 78% had accepted RT. Issues commonly perceived to be moderate to strong influencers of RT decisions were: concern about acute and long-term side effects; management of side effects; fear and anxiety regarding RT; lack of awareness of RT; lack of local availability of RT; and lack of RT information resources. Those who declined RT were significantly more likely to highlight practical difficulties with receiving RT. Although availability of RT is well recognized, other issues such as fear and anxiety about RT and perceived side effects appear to feature prominently in consumers' decisions. Perceived practical difficulties with receiving RT may have influenced those who declined RT. There may be a need for information resources, support services and interventions to increase awareness of RT. © 2016 John Wiley & Sons Australia, Ltd.

    On the Javalambre mountain in Spain, the Centro de Estudios de Fisica del Cosmos de Aragon (CEFCA) has setup a new wide field telescope, the JST/T250: a 2.55 m telescope with a plate scale of 22.67"/mm and a 3° diameter field of view. To conduct a photometric sky survey, a large format mosaic camera made of 14 individual CCDs is used in combination with filter trays containing 14 filters each of theses 101.7 x 96.5 mm in size. For this instrument, SCHOTT manufactured 56 specially designed steep edged bandpass interference filters which were recently completed. The filter set consists of bandpass filters in the range between 348,5 nm and 910 nm and a longpass filter at 915 nm. Most of the filters have FWHM of 14.5 nm and a blocking between 250 and 1050 nm with optical density of OD5. Absorptive color glass substrates in combination with interference filters were used to minimize residual reflection in order to avoid ghost images. Inspite of containing absorptive elements, the filters show the maximum possible transmission. This was achieved by using magnetron sputtering for the filter coating process. The most important requirement for the continuous photometric survey is the tight tolerancing of the central wavelengths and FWHM of the filters. This insures each bandpass having a defined overlap with its neighbors. In addition, the blocking of the filters is better than OD5 in the range 250-1050 nm. A high image quality required a low transmitted wavefront error (

    Transmission fluctuation spectrometry (TFS), as a new method of online and real-time particle analysis developed in recent years, can measure the particle size distribution and particle concentration simultaneously. In the preceding paper, high concentration effects on the TFS using band-pass filters were investigated by numerical simulation, and empirical expressions to correct the effects were obtained. This paper presents a study on the TFS measurements in which the particle concentration varies in a very wide dynamic range. Finally, reasonable results on both the particle size distribution and particle concentration are obtained by introducing empirical corrections into the inversion algorithm

    2018-02-01

    Reality shock is a critical representation of the gap between nursing education and clinical practice and it is important to explore the level of reality shock among nurses. However, there is no relevant instrument to assess the level of reality shock in South Korea. The purpose of this is to determine the validity and reliability of the Korean version of the Environmental Reality Shock-Related Issues and Concerns instrument. A cross-sectional study design was used in this study. The data collection was conducted in selected 15 hospitals in South Korea. A convenience sample of 216 newly graduated nurses participated in the study. The Korean version of the Environmental Reality Shock-Related Issues and Concerns instrument was developed through the forward-backward translation technique, and revision based on feedback from expert groups. The internal consistency reliability was assessed using Cronbach's alpha, and the construct validity was determined via exploratory and confirmatory factor analysis. The Korean version of the Environmental Reality Shock-Related Issues and Concerns has reliable internal consistency (Cronbach's alpha=0.91). Exploratory factor analysis revealed five factors including job, relationships, expectations, private life, and performance, which explained 61.92% of variance. The factor loadings ranged from 0.451 to 0.832. The five-factor structure was validated by confirmatory factor analysis (RMR0.9). It was concluded that the Korean version of the Environmental Reality Shock-Related Issues and Concerns instrument has satisfactory construct validity and reliability to measure the reality shock of newly graduated nurses in South Korea.

    There are few data on the frequency and current management of clinical ethical issues related to care of seriously ill dialysis patients in free-standing dialysis facilities. To examine the extent of clinical ethical challenges experienced by care providers in free-standing facilities and their perceptions about how those issues are managed. A total of 183 care providers recruited from 15 facilities in North Carolina completed a survey regarding the occurrence and management of ethical issues in the past year. Care plan meetings were observed at four of the facilities for three consecutive months. Also, current policies and procedures at each of the facilities were reviewed. The two most frequently experienced challenges involved dialyzing frail patients with multiple comorbidities and caring for disruptive/difficult patients. The most common ways of managing ethical issues were discussions in care plan meetings (n = 47) or discussions with the clinic manager (n = 47). Although policies were in place to guide management of some of the challenges, respondents were often not aware of those policies. Also, although participants reported that ethical issues related to dialyzing undocumented immigrants were fairly common, no facility had a policy for managing this challenge. Participants suggested that all staff obtain training in clinical ethics and communication skills, facilities develop ethics teams, and there be clear policies to guide management of ethical challenges. The scope of ethical challenges was extensive, how these challenges were managed varied widely, and there were limited resources for assistance. Multifaceted efforts, encompassing endeavors at the individual, facility, organization, and national levels, are needed to support staff in improving the management of ethical challenges in dialysis facilities.

    Roller, Sarah; Pippins, Raqiyyah

    2010-01-01

    Over the past decade, the liability risks associated with food and beverage product marketing have increased significantly, particularly with respect to nutrition and health-related product benefit claims. FDA and FTC enforcement priorities appear to have contributed to the increasing liability trends that are associated with these nutrition and health-related claims. This article examines key enforcement and litigation developments involving conventional food and beverage product marketing claims during the first 18 months of President Obama's administration: Part I considers FDA enforcement priorities and recent warning letters; Part II considers FTC enforcement priorities, warning letters, and consent orders; and Part III considers the relationship between FDA and FTC enforcement priorities and recent false advertising cases brought by private parties challenging nutrition and health-related marketing claims for food and beverage products. The article makes recommendations concerning ways in which food and beverage companies can help minimize liability risks associated with health-related marketing claims. In addition, the article suggests that federal policy reforms may be required to counter the perverse chilling effects current food liability trends appear to be having on health-related marketing claims for food and beverage products, and proposes a number of specific reforms that would help encourage the responsible use of well-substantiated marketing claims that can help foster healthy dietary practices. In view of the obesity prevention and other diet-related public health priorities of the Obama administration, the article suggests that this is an opportune time to address the apparent chilling effects increasing food liability risks are having on nutrition and health-related marketing claims for healthy food and beverage products, and potential adverse consequences for public health.

    Between 1990 and 2003, there were 668 subway-related fatalities in New York City. However, subway-related trauma remains an understudied area of injury-related morbidity and mortality. The objective of this study was to characterize the injuries and events leading up to the injuries of all patients admitted after subway-related trauma. We conducted a retrospective case series of subway-related trauma at a Level I trauma center from 2001 to 2016. Descriptive epidemiology of patient demographics, incident details, injuries, and outcomes were analyzed. Over 15 years, 254 patients were admitted for subway-related trauma. The mean (standard error of the mean) age was 41 (1.0) years, 80% were male (95% confidence interval [CI] 74-84%) and median Injury Severity Score was 14 (interquartile range [IQR] 5-24). The overall case-fatality rate was 10% (95% CI 7-15%). The most common injuries were long-bone fractures, intracranial hemorrhage, and traumatic amputations. Median length of stay was 6 days (IQR 1-18 days). Thirty-seven percent of patients required surgical intervention. At the time of injury, 55% of patients (95% CI 49-61%) had a positive urine drug or alcohol screen, 16% (95% CI 12-21%) were attempting suicide, and 39% (95% CI 33-45%) had a history of psychiatric illness. Subway-related trauma is associated with a high case-fatality rate. Alcohol or drug intoxication and psychiatric illness can increase the risk of this type of injury. Copyright © 2018 Elsevier Inc.

    Full Text Available This article focuses on development of Russian-Lithuanian economic ties. The research and practical significance of this study lies in the identification of the sources of modern Russian-Lithuanian economic cooperation and the prospects of future mutually beneficial economic relations. The first attempt at establishing economic relations was made in 1919. However, young Lithuanian Republic gravitated towards the West, severing ties with the Russian market. However, the initiatives of Lithuanian authorities did not result in successful state building, and the economic situation remained unchanged. The USSR leadership made an effort to improve the living conditions in post-war Lithuania. There were some mistakes made in the relations with the local population that resulted in Lithuanians’ resistance to sovietisation. However, in the conditions of post-war restoration of national economy and acute deficit of material and human resources, the Soviet leadership managed not only to reform and develop a socialistic economy in Lithuania but also to turn it into an industrial republic with developed agriculture and modern manufacturing facilities, whose major industries manufactured products used in nuclear and space technologies, aviation and navigation. The research shows that the post-Soviet period led to a dramatic change in Russian-Lithuanian economic relations; however, these relations retained potential for future development.

    In the present study, we simulated clinical scenarios by explicitly describing the history and clinical and histological features of hypothetical patients presenting with oral lichen planus (OLP), oral lichenoid lesion, and epithelial dysplasia in a self-designed questionnaire. By doing so, we aimed to elicit a diagnosis from oral pathologists and trainees, analyze their responses, appraise issues, and propose solutions regarding the diagnosis of OLP. The questionnaire was distributed to 100 oral pathologists and trainees in South India. Six questions were designed to assess awareness of the diagnostic aspects of OLP. Ten questions were hypothetical clinical scenarios (HCS) devised to evaluate respondents' knowledge of diagnostic guidelines and the criteria used by the respondents to render a diagnosis. There were 60 of 100 responses to the questionnaire. More than half the respondents were aware of the World Health Organization and modified guidelines of OLP. We observed considerable variations in diagnoses for the HCS. Our study illustrates the ambiguity in rendering an accurate diagnosis, despite adequate guidelines. Based on the responses for the HCS, we hypothesized that changes in the distribution (unilateral or bilateral) and clinical characteristic of OLP, and habits of patients, have a significant bearing on the clinical and final diagnoses of the lesion. © 2016 John Wiley & Sons Australia, Ltd.

    The radioactivities of the naturally occurring radionuclides ( 226 Ra, 228 Ra, 228 Th and 40 K) and a fallout nuclide 137 Cs) in books produced in Japan in the 20th century were measured by gamma-ray spectrometry to obtain information on radiation emitted from books. The respective concentration ranges of 226 Ra, 228 Ra, 228 Th, 40 K, and 137 Cs were 0.2-6.4, 0.4-11.2, 0.3-11.3, 1-112, and 0-3.6 Bq kg -1 . X-ray diffraction spectra of the papers used in book printing showed that pyrophyllite, talc, kaolinite, and calcium carbonate were contained as fillers. A comparison of the radioactivity contents of the pulp and filler indicated that most of 226 Ra, 228 Ra, and 228 Th in the books was present in the filler whereas 137 Cs was in the pulp. The pattern of the concentration of each nuclide vs. the year of issue of the book was investigated. Patterns for the naturally occurring radionuclides were similar and were explained by the kinds of filler used. The pattern for 137 Cs differed from the patterns of the naturally occurring radionuclides, having a marked peak in the mid-1960s. (author)

    Astrobiology is the study of the origin of life on Earth and the distribution of life in the Universe. Its multidisciplinary approach, social and philosophical implications, and appeal within the discipline and beyond make astrobiology a uniquely qualified subject for general science education. In this study, student knowledge and opinions on astrobiology topics were investigated. Eighty-nine students in their last year of compulsory education (age 15) completed a written questionnaire that consisted of 10 open questions on the topic of astrobiology. The results indicate that students have significant difficulties understanding the origin of life on Earth, despite exposure to the topic by way of the assigned textbooks. The students were often unaware of past or present achievements in the search for life within the Solar System and beyond, topics that are far less commonly seen in textbooks. Student questionnaire answers also indicated that students had problems in reasoning and critical thinking when asked for their opinions on issues such as the potential for life beyond Earth, the question of whether UFOs exist, or what our place is in the Universe. Astrobiology might help initiate student awareness as to current thinking on these matters and should be considered for general science education.

    Full Text Available When nine million foreigners visited Japan in 2013, the federal government set a goal to attract an additional two and a half million visitors including medical tourists by 2020. This research investigates the attitudes and concerns of Japanese nurses when they are in a situation dealing with foreign patients. The data were collected from March through September 2010, from 114 nurses at three hospitals, in close proximity to popular tourist destinations in Hiroshima. A questionnaire was developed for this research, named Mari Meter, which included a section to write answers to an open question for the nurses to express their opinions. These responses were examined statistically and by word analysis using Text Mining Studio. Japanese nurses expressed greatest concern about payment options, foreign language skills, and issues of informed consent, when dealing with foreigners. The results confirm that, in order to provide a high quality of patient care, extra preparation and a greater knowledge of international workers and visitors are required by nursing professionals in Japan.

    The tremendous expansion of data analytics and public and private big datasets presents an important opportunity for pre-clinical drug discovery and development. In the field of life sciences, the growth of genetic, genomic, transcriptomic and proteomic data is partly driven by a rapid decline in experimental costs as biotechnology improves throughput, scalability, and speed. Yet far too many researchers tend to underestimate the challenges and consequences involving data integrity and quality standards. Given the effect of data integrity on scientific interpretation, these issues have significant implications during preclinical drug development. We describe standardized approaches for maximizing the utility of publicly available or privately generated biological data and address some of the common pitfalls. We also discuss the increasing interest to integrate and interpret cross-platform data. Principles outlined here should serve as a useful broad guide for existing analytical practices and pipelines and as a tool for developing additional insights into therapeutics using big data.

    To explore the influence of administrative aspects of a nutrition education program with peer educators delivering the program. Telephone interviews with peer educators trained to deliver La Cocina Saludable, a nutrition education program for Hispanics. Open- and closed-ended questions. Abuelas (grandmothers) recruited and trained as peer educators for the program. The sample included peer educators no longer teaching (22%), currently teaching (30%), and who never taught after training. Motives and incentives for becoming peer educators, challenges for peer educators, and reasons peer educators withdrew from the program. Descriptive statistics were used to analyze quantitative data from the closed-ended questions. Qualitative analysis was applied to data from open-ended questions. Working with community and learning about nutrition were prime motivators. Recruiting participants and coordination of classes appeared to be major challenges. Personal issues and traveling in a large geographic area were cited as the main reasons for quitting. The effectiveness of using peer educators for La Cocina Saludable may be improved through empowerment, additional training, a structured and equitable reimbursement system, and assistance to carry out administrative tasks.

    This investigation employs categorical content analysis processes as a mechanism to examine trends and issues in a sampling of highly cited (100+) literature in special education journals. The authors had two goals: (a) broadly identifying trends across publication type, content area, and methodology and (b) specifically identifying articles with disaggregated outcomes for students with learning disabilities (LD). Content analyses were conducted across highly cited (100+) articles published during a 20-year period (1992-2013) in a sample ( n = 3) of journals focused primarily on LD, and in one broad, cross-categorical journal recognized for its impact in the field. Results indicated trends in the article type (i.e., commentary and position papers), content (i.e., reading and behavior), and methodology (i.e., small proportions of experimental and quasi-experimental designs). Results also revealed stability in the proportion of intervention research studies when compared to previous analyses and a decline in the proportion of those that disaggregated data specifically for students with LD.

  3. A Review of Issues Related to Data Acquisition and Analysis in EEG/MEG Studies.

    2017-05-31

    Electroencephalography (EEG) and magnetoencephalography (MEG) are non-invasive electrophysiological methods, which record electric potentials and magnetic fields due to electric currents in synchronously-active neurons. With MEG being more sensitive to neural activity from tangential currents and EEG being able to detect both radial and tangential sources, the two methods are complementary. Over the years, neurophysiological studies have changed considerably: high-density recordings are becoming de rigueur; there is interest in both spontaneous and evoked activity; and sophisticated artifact detection and removal methods are available. Improved head models for source estimation have also increased the precision of the current estimates, particularly for EEG and combined EEG/MEG. Because of their complementarity, more investigators are beginning to perform simultaneous EEG/MEG studies to gain more complete information about neural activity. Given the increase in methodological complexity in EEG/MEG, it is important to gather data that are of high quality and that are as artifact free as possible. Here, we discuss some issues in data acquisition and analysis of EEG and MEG data. Practical considerations for different types of EEG and MEG studies are also discussed.

    Multiple sclerosis (MS) is a demyelinating and neurodegenerative disease of the central nervous system (CNS), most probably autoimmune in origin, usually occurring in young adults with a female/male prevalence of approximately 3:1. Women with MS in the reproductive age may face challenging issues in reconciling the desire for parenthood with their condition, owing to the possible influence both on the ongoing or planned treatment with the possible consequences on the disease course and on the potential negative effects of treatments on foetal and pregnancy outcomes. At MS diagnosis, timely counselling should promote informed parenthood, while disease evolution should be assessed before making therapeutic decisions. Current guidelines advise the discontinuation of any treatment during pregnancy, with possible exceptions for some treatments in patients with very active disease. Relapses decline during pregnancy but are more frequent during puerperium, when MS therapy should be promptly resumed in most of the cases. First-line immunomodulatory agents, such as interferon-β (IFN-β) and glatiramer acetate (GA), significantly reduce the post-partum risk of relapse. Due to substantial evidence of safety with the use of GA during pregnancy, a recent change in European marketing authorization removed the pregnancy contraindication for GA. This paper reports a consensus of Italian experts involved in MS management, including neurologists, gynaecologists and psychologists. This consensus, based on a review of the available scientific evidence, promoted an interdisciplinary approach to the management of pregnancy in MS women.

    A 2-day consensus conference was held to examine scientific and ethical issues in the application of deep brain stimulation for treating mood and behavioral disorders, such as major depression, obsessive-compulsive disorder, and Tourette syndrome. The primary objectives of the conference were to (1) establish consensus among participants about the design of future clinical trials of deep brain stimulation for disorders of mood, behavior, and thought and (2) develop standards for the protection of human subjects participating in such studies. Conference participants identified 16 key points for guiding research in this growing field. The adoption of the described guidelines would help to protect the safety and rights of research subjects who participate in clinical trials of deep brain stimulation for disorders of mood, behavior, and thought and have further potential to benefit other stakeholders in the research process, including clinical researchers and device manufactures. That said, the adoption of the guidelines will require broad and substantial commitment from many of these same stakeholders.

  7. Rethinking the costs related to global warming. A survey of the issues

    One approach to the economic analysis of global warming seeks to balance the costs of damage from or adaptation to it with the costs of mitigating it. The costs of adaptation and damage have been estimated using techniques of environmental evaluation, but are subject to a wide margin of uncertainty. The costs of mitigation, principally by reducing the emissions of CO 2 , have been estimated using different kinds of economic models, some of the results of which have suggested that very little abatement of carbon emissions is justified before the costs of abatement exceed the benefits of it in terms of foregone damage and adaptation costs. The paper analyses the extent to which this conclusion is a function of the modelling assumptions and techniques used, rather than likely practical outcomes, with regard to the models' treatment of unemployed resources, revenue recycling, prior distortions in the economy due to the tax system and possible dynamic effects from the introduction of a carbon-energy tax. It concludes that, with different and arguably more appropriate treatment of the above issues, especially when the secondary benefits of reducing CO 2 emissions are also taken into account, it is not clear that even substantial reductions in the use of fossil fuels will incur net costs, especially if there is the prospect of even moderate costs from global warming. 4 figs., 8 tabs., 95 refs

    Several continuous splits for wafer alignment target topography conditions to improve epitaxy film alignment were applied. The alignment evaluation among former layer pad oxide thickness (250 angstrom - 500 angstrom), drive oxide thickness (6000 angstrom - 10000 angstrom), nitride film thickness (600 angstrom - 1500 angstrom), initial oxide etch (fully wet etch, fully dry etch and dry plus wet etch) will be split to this experiment. Also various epitaxy deposition recipe such as: epitaxy source (SiHCl2 or SiCHCl3) and growth rate (1.3 micrometer/min approximately 2.0 micrometer/min) will be used to optimize the process window for alignment issue. All the reflectance signal and cross section photography of alignment target during NIKON stepper alignment process will be examined. Experimental results show epitaxy recipe plays an important role to wafer alignment. Low growth rate with good performance conformity epitaxy lead to alignment target avoid washout, pattern shift and distortion. All the results (signal monitor and film character) combined with NIKON's stepper standard laser scanning alignment system will be discussed in this paper.

    Determination of sorption distribution coefficients (K(d)) of organic compounds by a dynamic soil column chromatography (SCC) method was developed and validated. Eurosoil 4, quartz, and alumina were chosen as exemplary packing materials. Heterocyclic aromatic compounds were selected in the validation of SCC. The prerequisites of SCC with regard to column dimension, packing procedure, and sample injection volume are discussed. Reproducible soil column packing was achieved by addition of a pre-column and an HPLC pump for subsequent compression of the packed material. Various methods to determine retention times from breakthrough curves are discussed and the use of the half mass method is recommended. To dilute soil with inert material can prevent column-clogging and help to complete experiments in a reasonable period of time. For the chosen probe compounds, quartz rather than alumina proved a suitable dilution material. Non-equilibrium issue can be overcome by conducting the experiments under different flowrates and/or performing numerical simulation. Copyright 2010 Elsevier Ltd. All rights reserved.

    One option of the ASTRID prototype power conversion systems (PCS) is the steam cycle based on the Rankine cycle, which has been implemented in the past in France in the Phenix and Superphenix Sodium Fast Reactors, and is also being implemented in other SFRs in construction in the world (Russia, India, China). This paper is placed in the context of the Rankine cycle ameliorations and in particular on the Steam Generator (SG), developed by AREVA, from the safety point of view without significant penalty on cost. Therefore significant progresses are expected to reduce sodium/water reaction accident scenario impact as much by prevention as by mitigation. ASTRID project performed a thorough comparison of SG designs with regard to these safety requirements but also including increased sodium/water segregation (inlet and outlet of sodium implemented at the bottom of the SG), material issues and cost considerations. The design is based today on a monolithic SG with alloy 800 helical tubes but equipped with geometric specificities necessary for allowing the use of a single component per secondary loop. (authors)

    In preparation for and in support of a detailed R and D Plan for the Accelerator-Based Conversion (ABC) of weapons plutonium, an ABC Plant Layout Study was conducted at the level of a pre-conceptual engineering design. The plant layout is based on an adaptation of the Molten-Salt Breeder Reactor (MSBR) detailed conceptual design that was completed in the early 1070s. Although the ABC Plant Layout Study included the Accelerator Equipment as an essential element, the engineering assessment focused primarily on the Target; Primary System (blanket and all systems containing plutonium-bearing fuel salt); the Heat-Removal System (secondary-coolant-salt and supercritical-steam systems); Chemical Processing; Operation and Maintenance; Containment and Safety; and Instrumentation and Control systems. Although constrained primarily to a reflection of an accelerator-driven (subcritical) variant of MSBR system, unique features and added flexibilities of the ABC suggest improved or alternative approaches to each of the above-listed subsystems; these, along with the key technical issues in need of resolution through a detailed R ampersand D plan for ABC are described on the bases of the ''strawman'' or ''point-of-departure'' plant layout that resulted from this study

    The quality of indoor air in commercial buildings is dependent on the complex interaction between sources of indoor pollutants, environmental factors within buildings such as temperature and humidity, the removal of air pollutants by air-cleaning devices, and the removal and dilution of pollutants from outside air. To the extent that energy conservation measures (ECMs) may affect a number of these factors, the relationship between ECMs and indoor air quality is difficult to predict. Energy conservation measures may affect pollutant levels in other ways. Conservation measures, such as caulking and insulation, may introduce sources of indoor pollutants. Measures that reduce mechanical ventilation may allow pollutants to build up inside structures. Finally, heating, ventilation, and air-conditioning (HVAC) systems may provide surface areas for the growth of biogenic agents, or may encourage the dissemination of pollutants throughout a building. Information about indoor air quality and ventilation in both new and existing commercial buildings is summarized in this report. Sick building syndrome and specific pollutants are discussed, as are broader issues such as ventilation, general mitigation techniques, and the interaction between energy conservation activities and indoor air quality. Pacific Northwest Laboratory (PNL) prepared this review to aid the Bonneville Power Administration (Bonneville) in its assessment of potential environmental effects resulting from conservation activities in commercial buildings. 76 refs., 2 figs., 19 tabs.

    2010-04-01

    Drug regulatory agencies have traditionally assessed the quality, safety and efficacy of drugs, and the current paradigm dictates that a new drug should be licensed when the benefits outweigh the risks. By contrast, third-party payers base their reimbursement decisions predominantly on the health benefits of the drug relative to existing treatment options (termed relative efficacy; RE). Over the past decade, the role of payers has become more prominent, and time-to-market no longer means time-to-licensing but time-to-reimbursement. Companies now have to satisfy the sometimes divergent needs of both regulators and payers, and to address RE during the pre-marketing stages. This article describes the current political background to the RE debate and presents the scientific and methodological challenges as they relate to RE assessment. In addition, we explain the impact of RE on drug development, and speculate on future developments and actions that are likely to be required from key players.

    In this paper we compare numerical approximations for solving the Riemann problem for a hyperbolic two-phase flow model in two-dimensional space. The model is based on mixture parameters of state where the relative velocity between the two-phase systems is taken into account. This relative velocity appears as a main discontinuous flow variable through the complete wave structure and cannot be recovered correctly by some numerical techniques when simulating the associated Riemann problem. Simulations are validated by comparing the results of the numerical calculation qualitatively with OpenFOAM software. Simulations also indicate that OpenFOAM is unable to resolve the relative velocity associated with the Riemann problem.

    Full Text Available The issue of accounting depreciation is an older concern of this study's authors on the incidence over the true and fair view of the earning and the net value of the non- current assets. Proceeding from the consideration that the present depreciation methods, acknowleged by the accounting standards and regulations are not sufficient to render the reality of the irreversible impairment of the fixed assets nor that of the material and immaterial investment recovery we performed a research on the indicators reported by 20 companies in Cluj county and we applied a questionnaire to each entity on the depreciation methods used, their incidence on the true and fair view and their proposals for the completion of the depreciation methods. The objective of the research is to identify the most appropriate depreciation methods, truthfully illustrating the effects of the irreversible impairment on the net asset and on the earning, to introduce the excluded assests in the cathegory of the non-current assets ( like property and plant, goodwill, intangible assets created with ones own strengths and the enforcement of appropriate treatments to the revaluation differences and their own overhead investments. The International Accounting Standard IAS 16 - Property, plant and equipment refers to three depreciation methods: the straightline method, the diminishing balance method and the technical depreciation method (units of production method. In Romania only two of these methods are accepted: the straightline method, the diminishing balance method and the accelerated method was additionally instilled, which is used internationally in exceptional situations and not currently. The results of the research led us to the following conclusions: - for the depreciation of the machinery, facilities and technological equipments it is recommended to use the technical depreciation method or the units of production method; -taking into consideration the financial conception on

    Nurses are under a great deal of distress related to a variety of work stressors. Work related stress jeopardizes the mental and physical well being of nurses, as well as the quality of care provided for clients. The Occupational Safety and Health Act of 1970 holds employers responsible for the mental and physical well being of their employees. However, the regulations are not always straightforward concerning compensation claims for mental disabilities due to work stress. Recovery of claims is possible if standards (i.e., personal injury, causal relationship between injury and employment) are met. Requirements for recovery of physical/mental and mental/physical claims are agreed on by most states, whereas mental/mental claims are controversial among states and courts. Nurses can monitor and influence legislation to create requirements to encourage employers to develop preventive approaches to reducing work induced stress.

    2005-05-20

    We present a theoretical study of a supercontinuum (SC) continuous-wave (cw) optical source generation in highly nonlinear fiber and its noise properties through numerical simulations based on the nonlinear Schrödinger equation. Fluctuations of pump pulses generate substructures between the longitudinal modes that result in the generation of white noise and then in degradation of coherence and in a decrease of the modulation depths and the signal-to-noise ratio (SNR). A scheme for improvement of the SNR of a multiwavelength cw optical source based on a SC by use of the combination of a highly nonlinear fiber (HNLF), an optical bandpass filter, and a Fabry-Perot (FP) filter is presented. Numerical simulations show that the improvement in modulation depth is relative to the HNLF's length, the 3-dB bandwidth of the optical bandpass filter, and the reflection ratio of the FP filter and that the average improvement in modulation depth is 13.7 dB under specified conditions.

    To evaluate the influence of obesity, fertility status, and androgenism scores on health-related quality of life in women with polycystic ovary syndrome (PCOS). Cross-sectional, correlational. Private reproductive endocrinology practice in two southeast U.S. cities. Convenience sample of 128 women with PCOS, half of whom were attempting to conceive in addition to being treated for PCOS. Most were White (97%), married (78%), with a mean age of 30.4 years (SD +/- 5.5). The Health-Related Quality of Life Questionnaire (PCOSQ) for women with polycystic ovary syndrome. A laboratory panel and clinical measures, including body mass index, waist-to-hip ratio, and degree of hirsutism. The most common health-related quality of life concern reported by women with PCOS was weight, followed in descending order by menstrual problems, infertility, emotions, and body hair. The psychological implications of PCOS are easily underestimated and have been largely ignored. Nursing has a pivotal role in recognizing these concerns and implementing therapy to improve quality of life in women with PCOS.

  11. Some issues related to polarized radiative transfer in a multilayer medium with a changing index of refraction

    International Nuclear Information System (INIS)

    Garcia, R D M

    2012-01-01

    A couple of issues raised in a recent work on Fresnel boundary and interface conditions for polarized radiative transfer are discussed. The first issue concerns a normalization that has to be performed on the transmission matrix relating the transmitted and incident Stokes vectors at a smooth interface between different materials. It was found that the normalization step is not performed in a correct way in many existing works and so the effects of the two most frequent discrepancies encountered in these works are evaluated for a simple model of an atmosphere-water system. The second issue has to do with a choice of the sign of the parallel component of the amplitude coefficient of reflection R l when constructing the reflection matrix that relates the reflected and incident Stokes vectors at a smooth interface. A computational approach based on the limit to the case with constant index of refraction is used to determine the appropriate sign of R l for polarized radiative transfer calculations in multilayers with different indices of refraction.

  12. Conflict of law issues related to Switzerland's participation in the Paris Nuclear Third Party Liability Regime

    International Nuclear Information System (INIS)

    Waldner, Michael

    2012-01-01

    In spite of the active role Switzerland played during the negotiation process of the Paris Convention, it only recently ratified the Convention including all its amending Protocols. The whole Paris regime will become binding for Switzerland only upon entry into force of the Protocols of 2004. Concurrently, the Federal Council will put into force a revised Swiss Nuclear Liability Act and ratify the Joint Protocol. Being a party to the Paris regime and the Joint Protocol, Switzerland will be in treaty relationships with Paris states and with Vienna states which are party to the Joint Protocol. This paper assesses the legal protection of Swiss victims and the liability risks faced by Swiss operators and other potential defendants (such as suppliers and builders) under the new legal regime with a particular view to conflict of laws issues. For the purpose of this assessment the paper examines which courts will be competent to hear claims of Swiss victims and against Swiss defendants in different scenarios, which law these courts should apply, whether or not the principle of legal channelling will apply and what the applicable liability amounts are. The assessment shows an ambiguous picture: Swiss operators, suppliers and builders clearly benefit from a higher degree of legal certainty. While in the absence of treaty relationships Swiss operators could potentially be sued before any foreign court, there will now be only one court with jurisdiction over claims of victims of convention states; Swiss suppliers and builders for their part will be protected by the principle of legal channelling, which basically exempts them from any liability risk. Swiss victims will benefit from treaty-backed entitlement to compensation from foreign operators; also, the judgements rendered in their favour will be enforceable in the whole convention territory; however, the limitation of the operator's liability in many Paris and Vienna states, raises doubts about whether the available funds

    An asymmetric MOSFET-C band-pass filter (BPF) with on chip charge pump auto-tuning is presented. It is implemented in UMC (United Manufacturing Corporation) 0.18 μm CMOS process technology. The filter system with auto-tuning uses a master-slave technique for continuous tuning in which the charge pump outputs 2.663 V, much higher than the power supply voltage, to improve the linearity of the filter. The main filter with third order low-pass and second order high-pass properties is an asymmetric band-pass filter with bandwidth of 2.730-5.340 MHz. The in-band third order harmonic input intercept point (IIP3) is 16.621 dBm, with 50 Ω as the source impedance. The input referred noise is about 47.455 μV rms . The main filter dissipates 3.528 mW while the auto-tuning system dissipates 2.412 mW from a 1.8 V power supply. The filter with the auto-tuning system occupies 0.592 mm 2 and it can be utilized in GPS (global positioning system) and Bluetooth systems. (semiconductor integrated circuits)

    Highlights: • We have developed a HTS five-pole dual-band bandpass filter using stub-loaded hair-pin resonators. • The proposed dual-band BPF can independently control of the center frequency. • Flexibly adjustment of the bandwidth can be achieved by the H-shaped waveguide. • The proposed BPF is evaluated by simulation and measurement with good agreement. - Abstract: A HTS dual-band bandpass filter is developed to obtain sharp-cut off characteristics for mobile communication systems. The filter is composed of five stub-loaded hair-pin resonators with H-shaped waveguides between them. The main advantage of the proposed filter is to allow independent control of the center frequency of the first and second bands. The bandwidths can be flexibly adjusted using the H-shaped waveguide. An electromagnetic simulator was used to design and analyze the filter, which have a 3.5-GHz center frequency and a 70-MHz (2%) bandwidth for the first band and a 5.0-GHz center frequency and a 100-MHz (2%) bandwidth for the second band. The filter was fabricated using YBa{sub 2}Cu{sub 3}O{sub y} thin film on an Al{sub 2}O{sub 3} substrate. Ground plane was fabricated using Au thin film. The measured frequency responses of the filter tally well with the simulated ones.

    This paper presents the design and implementation of quadrature bandpass sigma-delta modulator. A pole movement method for transforming real sigma-delta modulator to a quadrature one is proposed by detailed study of the relationship of noise-shaping center frequency and integrator pole position in sigma-delta modulator. The proposed modulator uses sampling capacitor sharing switched capacitor integrator, and achieves a very small feedback coefficient by a series capacitor network, and those two techniques can dramatically reduce capacitor area. Quantizer output-dependent dummy capacitor load for reference voltage buffer can compensate signal-dependent noise that is caused by load variation. This paper designs a quadrature bandpass Sigma-Delta modulator for 2.4 GHz low IF receivers that achieve 69 dB SNDR at 1 MHz BW and -1 MHz IF with 48 MHz clock. The chip is fabricated with SMIC 0.18 μm CMOS technology, it achieves a total power current of 2.1 mA, and the chip area is 0.48 mm2.

    Colwell, Janice C; McNichol, Laurie; Boarini, Joy

    The purpose of this study was to describe the practice of 796 ostomy nurses in North America in 2014 related to peristomal skin issues. Descriptive study. Participants were 796 wound, ostomy, and continence (WOC) and enterostomal therapy (ET) nurses currently practicing in the United States or Canada and caring for patients with ostomies. The collection of data occurred in conjunction with an educational program on peristomal skin complications and practice issues and solicited the participant's perception on the incidence and frequency of peristomal skin issues as well as on practice patterns. Participants attended an educational program. They were also asked to anonymously respond to multiple-choice questions on ostomy care management via an audience response system followed by discussion of each item and their responses. This descriptive study reports on the answers to the questions as well as the pertinent discussion points. Participants estimated that approximately 77.70% of their patients developed peristomal skin issues. The most commonly encountered problem was irritant contact dermatitis (peristomal moisture-associated skin damage). Contributing factors were inappropriate use of a pouching system owing to lack of follow-up after hospital discharge. Reported interventions for the prevention and management of peristomal skin issues included preoperative stoma site marking, use of a convex pouching system, and barrier rings. However, subsequent discussion revealed that the frequency of use of these products varied considerably. Participants identified shortened hospital stays, absence of preoperative stoma marking, and limited outpatient follow-up as contributing to development of peristomal skin problems. WOC and ET nurses estimate that more than three-quarters of persons living with an ostomy develop peristomal skin problems. Multiple interventions for managing these problems were identified, but some variability in management approaches emerged.

    The purpose of this exploratory and descriptive study is to contribute to the sparse return-to-work literature on head and neck cancer (HNC) survivors. Interview participants were asked to reflect upon their work-related experience with cancer by answering two specific questions: (1) What advice would you give someone who has been newly diagnosed with head and neck cancer? (2) What advice would you give to employers of these people? Data were gathered through 10 individual semi-structured in-depth interviews with HNC clinic patients at a regional cancer center's head and neck clinic in Ontario, Canada. A constant comparative method of theme development was used. Codes identified in and derived from the data were discussed by research team members until consensus was reached. Codes with similar characteristics were grouped together and used to develop overarching themes. Work-related advice for peers focused on personal self-care and interactions within workplaces. Work-related advice to employers focused on demonstrating basic human values as well as the importance of communication. The study results suggest HNC clinic patients should be proactive with employers and help to set reasonable expectations and provide a realistic plan for work to be successfully completed. HNC clinic patients should develop communication skills to effectively disclose their cancer and treatment to employers. In this exploratory study, HNC clinic patients' advice was solution-focused underscoring the importance of self-care and pro-active communication and planning with employers. Employers were advised to demonstrate core human values throughout all phases of the work disability episode beginning at diagnosis.

  20. Detecting and Characterizing Exoplanets with the WFIRST Coronagraph: Colors of Planets in Standard and Designer Bandpasses-SETI

    Science.gov (United States)

    Turnbull, Margaret

    The WFIRST mission is now envisioned to include a coronagraph for the purpose of direct detection of nearby exoplanets, including planets known to exist via radial velocity detection and new discoveries. Assuming that starlight rejection sufficient for planet detection (~1e-9) can be achieved, what can be learned about these planets given a realistic spectral resolution and signal-to-noise ratio? We propose to investigate the potential for WFIRST to efficiently discriminate planets from background sources, and to characterize planets in terms of important diagnostic atmospheric features, using broad- and intermediate band color data. We will map out this capability as a function of signal-to-noise ratio, bandpass location, and bandpass width. Our investigation will place emphasis on gas giants, ice giants, and mini-Neptunes (compatible with current AFTA-C baseline performance specifications), as well as a variety of super-Earths (an AFTA-C "stretch" goal). We will explore a variety of compositions, cloud types, phase angles, and (in the case of super-Earths with semi-transparent atmospheres) surface types. Noiseless spectra generated for these model planets will be passed through (a) standard bandpasses for comparison to prior work and (b) filter transmission curves corresponding to bandpasses of 5-20% over the full range of WFIRST's expected bandpass (400 - 1,000 nm). From this, filter combinations will be used to generate planet colors and find filter sets that most efficiently discriminate between planets and background sources, and between planets of different type. We will then repeat this exercise for S/N levels of 1-1,000 in order to (1) explore the true efficacy of broadband measurements in exoplanet studies, and (2) provide an estimate of total required integration time for a compelling WFIRST exoplanet program. To accomplish this, we will use model spectra for mini-Neptunes, and ice and gas giants of varying composition (Hu et al. 2013), and observed

  1. Talking about epilepsy: Challenges parents face when communicating with their child about epilepsy and epilepsy-related issues.

    2016-04-01

    The aim of this qualitative study was to explore the challenges that parents of children with epilepsy experienced when engaging in dialog with their child about epilepsy and epilepsy-related issues. Using a qualitative exploratory approach, interviews were conducted with 34 parents of children with epilepsy (aged 6-16 years), consisting of 27 mothers and 7 fathers. Data were transcribed verbatim and thematically analyzed. Findings revealed five main themes: normalizing epilepsy, the invisibility of epilepsy, information concealment, fear of misinforming the child, and difficulty in discussing particular epilepsy-related issues. Many of the communicative challenges experienced by parents impacted on their ability to engage openly in parent-child dialog about epilepsy in the home. Parents face specific challenges when choosing to communicate with their child about epilepsy, relating to creating a sense of normality, reducing fear of causing their child worry, and having a lack of epilepsy-related knowledge. Healthcare professionals who work closely with families living with epilepsy should remain mindful of the importance of discussing family communication surrounding epilepsy and the challenges parents of children with epilepsy face when talking about epilepsy within the home.

    2016-05-01

    The ways in which Parkinson's disease (PD) impacts, and is experienced by, the couple (i.e., the individual with PD and his or her spouse or other romantic partner) have not been fully elucidated. Such research is strongly warranted because when one member of a couple is chronically ill, it can cause major distress for not only the patient but also for his or her partner and their relationship. Therefore, the goal of this study was to examine how PD affects a couple's relationship. Data from 44 individual, in-depth interviews (with 21 persons with PD and 23 partners) revealed several challenges that PD commonly invokes in the patient-partner relationship, though most participants reported that PD had not decreased their overall relational closeness. The findings have significant practical implications for family-focused care. © The Author(s) 2016.

  4. Evaluation of Generic Issue 57: Effects of fire protection system actuation on safety-related equipment

    International Nuclear Information System (INIS)

    Lambright, J.; Bohn, M.; Lynch, J.; Ross, S.; Brosseau, D.

    1992-12-01

    Nuclear power plants have experienced actuations of fire protection systems (FPSs) under conditions for which these systems were not intended to actuate and also have experienced advertent actuations with the presence of a fire. These actuations have often damaged safety-related equipment. A review of the impact of past occurrences of both types of such events and their impact on plant safety systems, an analysis of the risk impacts of such events on nuclear power plant safety, and a cost-benefit analysis of potential corrective measures have been performed. Thirteen different scenarios leading to actuation of fire protection systems due to a variety of causes were identified. These scenarios ranged from inadvertent actuation caused by human error to hardware failure, and include seismic root causes and seismic/fire interactions. A quantification of these thirteen root causes, where applicable, was performed on generically applicable scenarios. This document, Volume 4, contains appendices E and F of this report

    International Nuclear Information System (INIS)

    Majumdar, S.; Pai, B.; Ryder, R.H.

    1987-01-01

    Recent design studies of a tokamak fusion power reactor and of various blankets have envisioned surface heat fluxes on the first wall ranging from 0.1 to 1.0 MW/m 2 , and end-of-life irradiation fluences ranging from 100 dpa for the austenitic stainless steels to as high as 250 dpa for postulated vanadium alloys. Some tokamak blankets, particularly those using helium or liquid metal as coolant/breeder, may have to operate at relatively high coolant pressures so that the first wall may be subjected to high primary stress in addition to high secondary stresses such as thermal stresses or stresses due to constrained swelling. The present paper focusses on the various problems that may arise in the first wall because of stress and high neutron fluence, and discusses some of the design solutions that have been proposed to overcome these problems

    2016-05-01

    Research purpose: The aim was to explore if the training of student psychometrists contributes to the relevance of this category in terms of the demographic profile of student psychometrists, the scope of services potentially provided by them and the content of training programmes. Motivation for the study: There is a paucity of research on training in the psychometrist category. Research design, approach and method: Data were obtained from the files of a cohort of student psychometrists who were registered in the Department of Psychology at the University of South Africa (UNISA. Follow-up surveys on training and work contexts were conducted amongst these students and their in-practice supervisors to confirm and supplement the data. In addition, a survey on the national availability of training programmes for psychometrists was conducted at South African universities. Main findings: Gender and racial skewness in terms of the demographic profile of the UNISA students seemed to reflect a national trend. In terms of the scope of services, training opportunities and perceived job opportunities for psychometrists seemed limited and despite the utilisation of the skills area in all the applied contexts, concerns related to the sectors being served were identified. With regard to the content of the training programmes, students and in-practice supervisors expressed a need for greater preparation in test use before related practical experience takes place. The importance of the university’s involvement during the practicum was also emphasised. Practical/managerial implications: Recommendations are made regarding the structure and content of training programmes. This information could be applied in adapting existing programmes and in developing new programmes. Contribution/value-add: Ultimately, these recommendations could contribute to the value of the psychometrist category as a professional resource relevant to a variety of settings.

The NRC program is of considerably broader scope than the ''Unresolved Safety Issues Plan'' required by Section 210. The NRC program does include plans for the resolution of ''Unresolved Safety Issues''; however, in addition, it includes generic tasks for the resolution of environmental issues, for the development of improvements in the reactor licensing process and for consideration of less conservative design criteria or operating limitations in areas where over conservatisms may be unnecessarily restrictive or costly

  8. Specifying the Concept of Future Generations for Addressing Issues Related to High-Level Radioactive Waste.

    Kermisch, Celine

    2016-12-01

    The nuclear community frequently refers to the concept of "future generations" when discussing the management of high-level radioactive waste. However, this notion is generally not defined. In this context, we have to assume a wide definition of the concept of future generations, conceived as people who will live after the contemporary people are dead. This definition embraces thus each generation following ours, without any restriction in time. The aim of this paper is to show that, in the debate about nuclear waste, this broad notion should be further specified and to clarify the related implications for nuclear waste management policies. Therefore, we provide an ethical analysis of different management strategies for high-level waste in the light of two principles, protection of future generations-based on safety and security-and respect for their choice. This analysis shows that high-level waste management options have different ethical impacts across future generations, depending on whether the memory of the waste and its location is lost, or not. We suggest taking this distinction into account by introducing the notions of "close future generations" and "remote future generations", which has important implications on nuclear waste management policies insofar as it stresses that a retrievable disposal has fewer benefits than usually assumed.

    On the idea that fatigue damage is localized at the microscopic scale, a scale smaller than the mesoscopic one of the Representative Volume Element (RVE), a three-dimensional two scale damage model has been proposed for High Cycle Fatigue applications. It is extended here to aniso-thermal cases and then to thermo-mechanical fatigue. The modeling consists in the micro-mechanics analysis of a weak micro-inclusion subjected to plasticity and damage embedded in an elastic meso-element (the RVE of continuum mechanics). The consideration of plasticity coupled with damage equations at micro-scale, altogether with Eshelby-Kroner localization law, allows to compute the value of microscopic damage up to failure for any kind of loading, 1D or 3D, cyclic or random, isothermal or aniso-thermal, mechanical, thermal or thermo-mechanical. A robust numerical scheme is proposed in order to make the computations fast. A post-processor for damage and fatigue (DAMAGE-2005) has been developed. It applies to complex thermo-mechanical loadings. Examples of the representation by the two scale damage model of physical phenomena related to High Cycle Fatigue are given such as the mean stress effect, the non-linear accumulation of damage. Examples of thermal and thermo-mechanical fatigue as well as complex applications on real size testing structure subjected to thermo-mechanical fatigue are detailed. (authors)

  10. Geoethical issues in long-term assessment of geohazards and related mitigation policies

    2015-04-01

    Long-term assessment of large-impact and relatively (or very) infrequent geohazards like earthquakes, tsunamis and volcanic eruptions is nowadays a common practice for geoscientists and many groups have been and are involved in producing global and regional hazard maps in response of an increasing demand of the society. Though the societal needs are the basic motivations for such studies, often this aspect is not pondered enough and a lack of communication between geoscientists and the society might be a serious limit to the effective exploitation of the hazard assessment products and to the development of adequate mitigation policies. This paper is an analysis of the role of geoscientists in the process of the production of long-term assessments of dangerous natural phenomena (such as mapping of seismic, tsunami and volcanic hazards), with special emphasis given to the role of communicators and disseminators (with respect to the general public, to authorities, to restricted specialized audiences…), but also of providers of active support to the planners who should be given key elements for making decision. Geoethics imposes geoscientists to take clear and full responsibilities on the products resulting from their assessments, but also to be aware that these products are valuable insofar they are scientifically sound, known, understandable, and utilizable by a wide universe of users.

    Full text: Statistical Parametric Mapping (SPM) is a software tool designed for the statistical analysis of functional neuro images, specifically Positron Emission Tomography and functional Magnetic Resonance Imaging, and more recently SPECT. This review examines some problems associated with the analysis of SPECT. A comparison of a patient group with normal studies revealed factors that could influence results, some that commonly occur, others that require further exploration. To optimise the differences between two groups of subjects, both spatial variability and differences in global activity must be minimised. The choice and effectiveness of co registration method and approach to normalisation of activity concentration can affect the optimisation. A small number of subject scans were identified as possessing truncated data resulting in edge effects that could adversely influence the analysis. Other problems included unusual areas of significance possibly related to reconstruction methods and the geometry associated with nonparallel collimators. Areas of extra cerebral significance are a point of concern - and may result from scatter effects, or mis registration. Difficulties in patient positioning, due to postural limitations, can lead to resolution differences. SPM has been used to assess areas of statistical significance arising from these technical factors, as opposed to areas of true clinical significance when comparing subject groups. This contributes to a better understanding of the effects of technical factors so that these may be eliminated, minimised, or incorporated in the study design.

    British Columbia's fisheries industry is worth hundreds of millions of dollars per year and is of great cultural significance to First Nations. While concern about the impact of seismic exploration is relatively recent LGL Limited has been examining the effects of seismic exploration on marine wildlife since 1974 with particular emphasis on the significance of underwater noise from air gun arrays and the effects of seismic hearing in fish and marine mammals such as seals and whales. Research programs have been conducted in the Gulf of Mexico, the west coast of North America, Cook Inlet, Bering Sea, Chukchi Sea and the Beaufort Sea. Studies have also been conducted throughout Arctic Canada, the coastal waters of Newfoundland, the Scotian Shelf, and the Bay of Fundy. This presentation described seismic noise sources, source levels, how source levels are measured, and the path of noise with reference to transmission loss, received levels, and ambient noise. Over the decades, there have not been large-scale demonstrated effects on fisheries in the areas where seismic exploration has occurred. Major collapses have not occurred in fisheries even in the most mature oil and gas fields. It was therefore concluded that seismic exploration can be conducted safely in the northern waters of British Columbia if the programs are carefully planned and if appropriate mitigation measures are in place with good quantitative monitoring by trained biologists. 5 figs.

    The Hanford Environmental Dose Reconstruction (HEDR) Project will estimate radiation doses people may have received from exposure to radioactive materials released during past operations at the US Department of Energy's (DOE) Hanford Site near Richland, Washington. The HEDR Project was initiated in response to public concerns about possible health impacts from past releases of radioactive materials from Hanford. The TSP recognized early in the project that special mechanisms would be required to effectively communicate to the many different concerned audiences. Accordingly, the TSP directed PNL to examine methods for communicating causes and effects of uncertainties in the dose estimates. After considering the directive and discussing it with the Communications Subcommittee of the TSP, PNL undertook a broad investigation of communications methods to consider for inclusion in the TSP's current communications program. As part of this investigation, a literature review was conducted regarding risk communications. A key finding was that, in order to successfully communicate risk-related information, a thorough understanding of the knowledge level, concerns and information needs of the intended recipients (i.e., the audience) is necessary. Hence, a preliminary audience analysis was conducted as part of the present research. This report summarizes the results of this analysis. 1 ref., 9 tabs.

    JNC is releasing information on the technical reliability for geological disposal of high-level radioactive waste (HLW) to public. However, the recognition and understanding of general public on the geological disposal of HLW are not satisfied. Recently more and more people are using the Internet, which is two-way, instant and open communication network. So JNC has offered the opportunity for discussing the topics related to geological disposal of HLW on the Internet web site since fiscal year 1999. In this fiscal year, the online forum was opened from January 25 to March 11. The forum was held on the web server independent from JNC so that discussion is done as fairly and objectively as possible. The event, which is the online discussion by university students in nation-wide, was specially held. The number of accesses to the forum significantly increased in this period compared to that of last two fiscal years. The adequate operation of the forum and the presentation of the information about geological disposal of HLW were surveyed by the questionnaire distributed to the participants. (author)

    1980-10-01

    Potential environmental impacts in reservoirs and downstream river reaches below dams that may be caused by the water level fluctuation resulting from development and operation of small scale (under 25MW) hydroelectric projects are identified. The impacts discussed will be of potential concern at only those small-scale hydroelectric projects that are operated in a store and release (peaking) mode. Potential impacts on physical and chemical characteristics in reservoirs resulting from water level fluctuation include resuspension and redistribution of bank and bed sediment; leaching of soluble organic matter from sediment in the littoral zone; and changes in water quality resulting from changes in sediment and nutrient trap efficiency. Potential impacts on reservoir biota as a result of water level fluctuation include habitat destruction and the resulting partial or total loss of aquatic species; changes in habitat quality, which result in reduced standing crop and production of aquatic biota; and possible shifts in species diversity. The potential physical effects of water level fluctuation on downstream systems below dams are streambed and bank erosion and water quality problems related to resuspension and redistribution of these materials. Potential biological impacts of water level fluctuation on downstream systems below dams result from changes in current velocity, habitat reduction, and alteration in food supply. These alterations, either singly or in combination, can adversely affect aquatic populations below dams. The nature and potential significance of adverse impacts resulting from water level fluctuation are discussed. Recommendations for site-specific evaluation of water level fluctuation at small-scale hydroelectric projects are presented.

    Full Text Available Inappropriate treatment of bile duct injury and traumatic biliary stricture may cause serious consequences such as recurrent cholangitis, formation of hepatolithiasis, and biliary cirrhosis. This article elaborates on the influencing factors for the effect of the repair of bile duct injury and traumatic biliary stricture, repair principles, timing of repair or reconstruction, and related methods and techniques. It is pointed out that if there is no significant local infection and the bile duct wall defect is <2 cm, end-to-end anastomosis should be used for repair; if the bile duct wall defect is >2 cm, Roux-en-Y hepaticojejunostomy should be used for reconstruction. If the upper wall of the bile duct had a large defect and the lower wall has an integral structure, pedicled umbilical vein graft, pedicled jejunal wall seromuscular flap, or gastric wall seromuscular flap should be used for repair. The patients with severe congestion and edema at the site of injury should be treated with sufficient external drainage of the injured bile duct and then selective repair or reconstruction. Patients with hepatic duct stenosis in the liver lobe or hepatic segments and liver tissue atrophy can be treated with hepalobectomy or segmental hepatectomy. The key to successful repair is exposure and removal of high hilar bile duct stricture, while segmental hepatectomy of the Ⅳb segment can fully expose the left and right hepatic pedicles and help with the incision of the left and right hepatic ducts and secondary hepatic ducts, and therefore, it is a good method for exposing high bile duct stricture.

    Full Text Available A serious social problem is drug use, which is very widespread all over the world. Drugs are a terrible problem whose seriousness becomes more visible every day. Problems caused by drug abuse and illegal trafficking are among the most serious problems faced by the world today but also threatening future generations. After the First World War, drugs began to be consumed on a large scale. Up to the end of the 30s, they were legal. Their marketing over time has led to enormous profits outlaw, making drugs an invaluable source for the black market. Scourge illicit drug trafficking from South America and the Middle East comprised the whole the planet. Governments have begun to allocate more resources to the fight against drugs, but the processes were slow because the problem was very complex. The impact was very high among young people who out of curiosity, terrible or solidarity with the entourage, have begun to consume. The Romanian society was caught by surprise by this drug scourge, coming out so very serious problems both in justice and in the medical world. Weak reactions and untrained authorities have favored the phenomenon of drug abuse that has come to be devastating. Drug use is a high-risk activity. Optimism and illusion of maintaining self-control is also dangerous because it affects reasoning. The drug consumer becomes not only an unfortunate person, but also a social problem. Changes made by traffickers are evident in street-related lawsuits: thefts, arsonists, assassinations. We are all affected in some way by drug trafficking. The extent of the problem current narcotics outweighs the concerns of the police forces and the medical world, constituting a threat to the economic and social order of the world.

  18. Nonlinear association criterion, nonlinear Granger causality and related issues with applications to neuroimage studies.

    2016-03-15

    Quantifying associations in neuroscience (and many other scientific disciplines) is often challenged by high-dimensionality, nonlinearity and noisy observations. Many classic methods have either poor power or poor scalability on data sets of the same or different scales such as genetical, physiological and image data. Based on the framework of reproducing kernel Hilbert spaces we proposed a new nonlinear association criteria (NAC) with an efficient numerical algorithm and p-value approximation scheme. We also presented mathematical justification that links the proposed method to related methods such as kernel generalized variance, kernel canonical correlation analysis and Hilbert-Schmidt independence criteria. NAC allows the detection of association between arbitrary input domain as long as a characteristic kernel is defined. A MATLAB package was provided to facilitate applications. Extensive simulation examples and four real world neuroscience examples including functional MRI causality, Calcium imaging and imaging genetic studies on autism [Brain, 138(5):13821393 (2015)] and alcohol addiction [PNAS, 112(30):E4085-E4093 (2015)] are used to benchmark NAC. It demonstrates the superior performance over the existing procedures we tested and also yields biologically significant results for the real world examples. NAC beats its linear counterparts when nonlinearity is presented in the data. It also shows more robustness against different experimental setups compared with its nonlinear counterparts. In this work we presented a new and robust statistical approach NAC for measuring associations. It could serve as an interesting alternative to the existing methods for datasets where nonlinearity and other confounding factors are present. Copyright © 2016 Elsevier B.V. All rights reserved.

    The European network of excellence NULIFE (Nuclear plant life prediction) has been launched under the Euratom Framework Programme with a clear focus on integrating safety-oriented research on materials, structures and systems and exploiting the results of this integration through the production of harmonised lifetime assessment methods. NULIFE will help provide a better common understanding of the factors affecting the lifetime of nuclear power plants which, together with associated management methods, will help facilitate safe and economic long term operation of existing nuclear power plants. In addition, NULIFE will help in the development of design criteria for future generations of nuclear power plant. NULIFE was kicked-off in October 2006 and will work over a 5-year period to create a single organization structure, capable of providing harmonised research and development (R and D) at European level to the nuclear power industry and the related safety authorities. Led by VTT (Technical Research Centre of Finland), the project has a total budget in excess of 8 million euros, with over 40 partners drawn from leading research institutions, technical support organisations, power companies and manufacturers throughout Europe. NULIFE also involves many industrial organizations and, in addition to their R and D contributions, these take part in a dedicated End User Group. The importance of the long term operation of the plants has been recognized at European level, in the strategic research agenda of SNE TP (Sustainable Nuclear Energy Technology Platform). In NULIFE, the joint EU-wide coordinated research strategy for plant life integrity management and long term operation has been defined. Based on NULIFE business plan, the discussion of long-term business plan, operational model and statutes of the future NULIFE institute has been started. NULIFE maintains the sustainability of nuclear power by focusing on the continued, 60+ years of safe operation of nuclear power

    2009-07-01

    Econometric modeling of healthcare costs and expenditures has become an important component of decision-making across a wide array of real-world settings. The objective of this article is to provide a brief summary of important conceptual and analytical issues involved in econometric healthcare cost modeling. To this end, the article explores: outcome measures typically analyzed in such work; the decision maker's perspective in econometric cost modeling exercises; specific analytical issues in econometric model specification; statistical goodness-of-fit testing; empirical implications of "upper tail" (or "high cost") phenomena; and issues relating to the reporting of findings. Some of the concepts explored here are illustrated in light of samples drawn from the 2005 Medical Expenditure Panel Survey and the 2005 Nationwide Inpatient Sample. Analysts of healthcare cost data have at their disposal an increasingly sophisticated tool kit for analyzing such data that can in principle and in fact yield increasingly interesting insights into data structures. Yet for such analyses to usefully inform policy decisions, the manner in which such studies are designed, undertaken, and reported must accommodate considerations relevant to the decision-making community. The article concludes with some preliminary thoughts on how such bridges might be constructed.

    Several numerical models have been prepared to deal with various time- and spatial-scale issues related to radioactive cesium migration in environment in Fukushima area. The SACT (Soil and Cesium Transport) model developed by the Japan Atomic Energy Agency (JAEA) predicts middle- to long-term evolution of radioactive cesium distribution due to soil erosion, subsequent sediment transport and deposition, and radioactive cesium migration based on the Universal Soil Loss Equation (USLE). The TODAM (Time-dependent One-dimensional Degradation and Migration) model, iRIC/Nays2D and the FLESCOT (Flow, Energy, Salinity, Sediment, Contaminant Transport) model are one-, two- and three-dimensional river/reservoir/coastal models, respectively. Based on conservation equations of sediment and radioactive cesium, they treat advection and diffusion of suspended sediment and cesium, deposition of sediment to bed, re-suspension from bed and adsorption/desorption of radioactive cesium. These models are suitable for small and short time scale issues such as high discharges of sediment and radioactive cesium from rivers due to heavy rainfall events. This paper describes fragments of the JAEA’s approaches of modeling to deal with the issues corresponding to radioactive cesium migration in environment with some case studies. (author)

    The development and negotiation of an Engineering, Procurement and Construction (EPC) contract is a multi-disciplined and time consuming process. Relative to the first wave on new nuclear build projects of the 1950's - 1970's, today's EPC contracts are more complex for a variety of reasons including more demanding regulatory and environmental requirements, global supply chain versus localization issues and different world wide economic considerations. This paper discusses the impacts of some of these challenges on developing an EPC contract in today's Nuclear Renaissance. (authors)

    Rosemount pressure transmitters are extensively used in both safety and non-safety applications in US nuclear power plants. They are used to measure pressure, flow, and water level. Rosemount pressure transmitter models 1151, 1152, 1153A, 1153, and 1154 use a fill oil to hydraulically transmit process pressure exerted on outer isolating diaphragms to internal diaphragms. The resulting deflection of the internal diaphragms changes the distance between them and a central diaphragm separating the transmitter interior into two volumes. The change in distance is measured as a change in electrical capacitance between the isolating diaphragms and the central diaphragm and can be related to differential pressure. The fill oil also functions as a dielectric. It has been well established that this fill oil can potentially leak over time, decreasing transmitter accuracy and increasing transmitter response time. Ultimately, the transmitter can fail. An extensive effort has been expended by the nuclear power industry collectively to analyze this issue and develop technically sound and reasonable requirements to mitigate the effects of oil loss in Rosemount pressure transmitters. Despite this, technical concerns have still been raised regarding the technical validity of the past analyses of this problem and its scope. In May 1993, the NRC created an internal group to comprehensively review the Rosemount issue and the NRC's action in addressing it to ensure that all available technical information has been considered. Because this issue remains of active technical interest and because the past work on this subject has been done by many different groups and organizations, EPRI has prepared this report to thoroughly document the current technical understanding of this issue, to perform additional analysis, and to identify any appropriate additional technical research activities regarding oil loss in Rosemount pressure transmitters

They share same language, dress and culture and also six watercourses, namely the Indus, Jhelum, Chenab, Ravi, Sutlej and Beas, along with their numerous tributaries. Pakistan, like other countries of the region depends heavily on agriculture, with the greater part of the population relying on it for livelihood. As a result, water is not only vital for everyday needs, but a critical source for economic development. Water is a resource on which there is dependency of economy and no substitute. Pakistan and India are close neighbors and lied in South East of Asia. Apart from sharing border and history both the countries have various same customs and traditions.Both countries gained independence in 1947 from British Government, from the day of independence Pakistan has been facing lots of internal and external challenges. Apart from other conflicts, water issues also exist between Pakistan and India. After the nine years negotiation with the help of World Bank, they solved this issue but after some time it started again.

    2009-07-01

    Patient self-management of disease is increasingly supported by technologies that can monitor a wide range of behavioural and biomedical parameters. Incorporated into everyday devices such as cell phones and clothes, these technologies become integral to the psychosocial aspects of everyday life. Many technologies are likely to be marketed directly to families with ill members, and families may enlist the support of clinicians in shaping use. Current ethical frameworks are mainly conceptualised from the perspective of caregivers, researchers, developers and regulators in order to ensure the ethics of their own practices. This paper focuses on families as autonomous decision-makers outside the regulated context of healthcare. We discuss some morally relevant issues facing families in their decisions to monitor the health-related behaviours of loved ones. An example - remote parental monitoring of adolescent blood glucose - is presented and discussed through the lens of two contrasting accounts of ethics; one reflecting the predominant focus on health outcomes within the health technology assessment (HTA) framework and the other that attends to the broader sociocultural contexts shaping technologies and their implications. Issues discussed include the focus of assessments, informed consent and child assent, and family co-creation of system characteristics and implications. The parents' decisions to remotely monitor their child has relational implications that are likely to influence conflict levels and thus also health outcomes. Current efforts to better integrate outcome assessments with social and ethical assessments are particularly relevant for informed decision-making about health monitoring technologies in families.

    A combination of a SrF 2 entrance window and a photomultiplier with the Cu-BeO first dynode coated with KCl film realizes the bandpass photon detector with the FWHM of 0.47 eV centered at 9.43 eV and the sensitivity improved by about one order of magnitude in comparison with the detector without the KCl film. The overall energy resolution of the inverse photoemission spectrometer consisting of an electron gun with a BaO cathode and the new detector has been estimated to be 0.56 eV using polycrystalline Au. Typical counting rate is 10 2 -10 3 counts/(μA s) for unoccupied states near the Fermi level of the Au at an acceptance angle of about 0.8π sr with an Al collecting mirror. (orig.)

    2013-01-01

    In this work, a library of 3D lumped components completely embedded in the thinnest, multilayer LCP (M-LCP) stack- up with four metallization layers and 100 μm of total thickness, is reported for the first time. A vertically and horizontally interdigitated capacitor, realized in this stack-up, provides higher self resonant frequency as compared to a similarly sized conventional parallel plate capacitor. Based on the above mentioned library, a miniaturized bandpass filter is presented for the GPS application. It utilizes mutually coupled inductors and is the smallest reported in the literature with a size of (0.035×0.028×0.00089)λg. Finally, the same filter realized in a competing ceramic technology (LTCC) is compared in performance with the ultra-thin M-LCP design. The M-LCP module presented in this work is inherently exible and offers great potential for wearable and conformal applications.

NbN films have been deposited on both sides of (100) oriented, 250 {mu}m thick, MgO substrates with a high crystalline texture quality. The aim was to investigate the performances and the maximum achievable operating frequency in an NbN based RSFQ modulator front-end of an ADC in the 4 K-10 K temperature range. We observed that Ta{sub x}N thin films can be tuned from an insulating phase to a superconducting phase (Tc {approx}4K) by varying the nitrogen content during sputter deposition while the barrier height of MgO can also be controlled by deposition conditions and by tri-layer postdeposition annealing. Junction properties (Jc{approx}10-25 kA/cm{sup 2}), Mac Cumber parameter and RnIc product measured up to 1 mV are shown to be controlled by the reactive sputtering conditions. We have designed three pole band-pass filters and resonators in a micro-strip configuration and studied the junction coupling with the filters. We will show that a sigma-delta NbN technology is a suitable solution for analogue-to-digital conversion in the future generations of telecommunication satellites to achieve high sampling frequency and large bandwidth at high carrier frequency signal.

    Little is published about the disclosure of parents' own HIV status to their children in Africa. Research shows that keeping family secrets from children, including those related to a parent's HIV status, can be detrimental to their psychological well-being and to the structure of the family. Further, children with HIV-positive parents have been shown to be more vulnerable to poorer reproductive health outcomes. This qualitative study in Botswana conducted in-depth interviews among 21 HIV-positive parents on antiretroviral therapy. The data revealed that parents found discussing the issue of HIV with children difficult, including disclosing their own HIV status to them. Reasons for disclosing included: children being HIV positive, the rest of the family knowing, or the parent becoming very sick. Reasons for not disclosing included: believing the child to be too young, not knowing how to address the issue of HIV, that it would be "too painful" for the child/ren. Concern that other people might find out about their status or fear of children experiencing stigmatising behaviour. Interviews elucidated the difficulty that parents have in discussing their own HIV status and more general sexual health issues with their children. Parents and other guardians require support in managing age-appropriate disclosure to their children. This may further enable access to forums that can help children cope with their fears about the future and develop life skills in preparation for dealing with relationships of a sexual nature and sexual health as children move into adulthood. In developing such support mechanisms, changing family roles in Botswana need to be taken into consideration and the role of other family members in the upbringing of children in Tswana society need to be recognised and utilised.

    Due to globalization and changes in the health care delivery system, there has been a gradual change in the attitude of the medical community as well as the lay public toward greater acceptance of euthanasia as an option for terminally ill and dying patients. Physicians in developing countries come across situations where such issues are raised with increasing frequency. As euthanasia has gained world-wide prominence, the objectives of our study therefore were to explore the attitude of physicians and chronically ill patients toward euthanasia and related issues. Concomitantly, we wanted to ascertain the frequency of requests for assistance in active euthanasia. Questionnaire based survey among consenting patients and physicians. The majority of our physicians and patients did not support active euthanasia or physician-assisted suicide (EAS), no matter what the circumstances may be P < 0.001. Both opposed to its legalization P < 0.001. Just 15% of physicians reported that they were asked by patients for assistance in dying. Both physicians 29.2% and patients 61.5% were in favor of withdrawing or withholding life-sustaining treatment to a patient with no chances of survival. Among patients no significant differences were observed for age, marital status, or underlying health status. A significant percentage of surveyed respondents were against EAS or its legalization. Patient views were primarily determined by religious beliefs rather than the disease severity. More debates on the matter are crucial in the ever-evolving world of clinical medicine.

    Assessment approaches and strategies useful in addressing important issues in section 316(b) of the 1972 Federal Water Pollution Control Act are illustrated in this report through the analysis and evaluation of the Prairie Island Nuclear Station 316(b) data base. The main issues in 316(b) demonstrations, cooling water intake operation and location, involve determining the impacts of entrainment and impingement. Entrainment impacts were addressed by applying the equivalent adult approach and correcting for inherent biases and by determining the through-plant survival of zooplankton. An assessment of impingement impacts was made by comparing for each of various species the number of fish impinged to estimates of population size. Densities of plankton and fish were compared between the intake area and an alternate area to determine if the location of the present intake minimizes impacts. No definitive conclusion relative to the best location of the intake could be made because of high year to year variability in the data and the differential dominance of trophic groups between areas

    A medical linear accelerator (LINAC) room must be properly shielded to limit the outside radiation exposure to an acceptable safe level defined by individual state and international regulations. However, along with this prime objective, some additional issues are also important. The current case-study was designed to unfold the issues related to over-shielded and unplanned treatment rooms for LINACs. In this connection, an apparently unplanned and over-shielded treatment room of 610 × 610 cm2 in size was compared with a properly designed treatment room of 762 × 762 cm2 in size ( i.e., by following the procedures and recommendations of the IAEA Safety Reports Series No. 47 and NCRP 151). Evaluation of the unplanned room indicated that it was over-shielded and that its size was not suitable for total body irradiation (TBI), although the license for such a treatment facility had been acquired for the installed machine. An overall 14.96% reduction in the total shielding volume ( i.e., concrete) for an optimally planned room as compared to a non-planned room was estimated. Furthermore, the inner room's dimensions were increased by 25%, in order to accommodate TBI patients. These results show that planning and design of the treatment rooms are imperative to avoid extra financial burden to the hospitals and to provide enough space for easy and safe handling of the patients. A spacious room is ideal for storing treatment accessories and facilitates TBI treatment.

    Moral judgment in relation to animal ethics issues has rarely been investigated. Among the research that has been conducted, studies of veterinary students have shown greater use of reasoning based on universal principles for animal than human ethics issues. This study aimed to identify if this was unique to students of veterinary and other animal-related professions. The moral reasoning of first year students of veterinary medicine, veterinary technology, and production animal science was compared with that of students in non-animal related disciplines of human medicine and arts. All students (n = 531) completed a moral reasoning test, the VetDIT, with animal and human scenarios. When compared with reasoning on human ethics issues, the combined group of students evaluating animal ethics issues showed higher levels of Universal Principles reasoning, lower levels of Personal Interest reasoning and similar levels of Maintaining Norms reasoning. Arts students showed more personal interest reasoning than students in most animal-related programs on both animal and human ethics issues, and less norms-based reasoning on animal ethics issues. Medical students showed more norms-based reasoning on animal ethics issues than all of the animal-related groups. There were no differences in principled reasoning on animal ethics issues between program groups. This has implications for animal-related professions and education programs showing that students' preference for principled reasoning on animal ethics issues is not unique to animal-related disciplines, and highlighting the need to develop student (and professional) capacity to apply principled reasoning to address ethics issues in animal industries to reduce the risk of moral distress.

  1. MDEP Design-Specific Common Position CP-EPRWG-02. Common position addressing Fukushima Daiichi-related issues

    International Nuclear Information System (INIS)

    2015-10-01

    A severe accident involving several units took place in Japan at Fukushima Daiichi nuclear power plant (NPP) in March 2011. The immediate cause of the accident was an earthquake followed by a tsunami coupled with inadequate provisions against the consequences of such events in the design. Opportunities to improve protection against a realistic design basis tsunami were not taken. As a consequence of the tsunami, safety equipment and the related safety functions were lost at the plant, leading to core damage in three units and subsequently to large radioactive releases (INES 7). Several studies have already been performed to better understand the accident progression and detailed technical studies are still in progress in Japan and elsewhere. In the meantime, on-going studies on the behaviour of NPPs in very severe situations, similar to Fukushima Daiichi, seek to identify potential vulnerabilities in plant design and operation; to suggest reasonably practicable upgrades; or to recommend enhanced regulatory requirements and guidance to address such situations. Likewise, agencies around the world that are responsible for regulating the design, construction and operation of EPR plants are engaged in similar activities. The MDEP EPR Working Group (EPRWG) members consist of members from the United States, the United Kingdom, France, Finland, China, India and Sweden. Because not all of these countries have completed the regulatory review of their EPR applications yet, this paper identifies common preliminary approaches to address potential safety improvements for EPR plants, as well as common general expectations for new nuclear power plants, as related to lessons learned from the Fukushima Daiichi accident or Fukushima Daiichi-related issues. After the safety reviews of the EPR design applications that are currently in review are completed, the regulators will update this paper to reflect their safety conclusions regarding the EPR design and how the design could be

    A commonly held perception is that disposal of spent nuclear fuel or high-level waste presents a risk of unprecedented duration. In 40 CFR 191, the EPA requires that projected releases of radioactivity be limited for 10,000 years after disposal with the intent that risks from the disposal repository be no greater than those from the uranium ore deposit from which the nuclear fuel was originally extracted. This study reviews issues involved in assessing compliance with the requirement. The determination of compliance is assumption dependent primarily due to uncertainties in dosi-metric data, and relative availability of the radioactivity for environmental transport and eventual assimilation by humans. A conclusion of this study is that, in time, a spent fuel disposal repository such as the projected Yucca Mountain Project Facility will become less hazardous than the original ore deposit

    There currently appears to be a general consensus on the relationship between time perspective and aging, such that (a) future time is perceived as more limited with age and (b) older people are more present-focused and less future-focused than younger people. At the same time, there are debates about whether these age differences are positively related to well-being and to what extent there are boundary conditions beyond which these age differences would cease to occur. The 8 manuscripts included in this Special Issue attempt to shed light on these debates. In doing so, they refine the dominant theoretical perspective on the topic-socioemotional selectivity theory-and introduce new theoretical perspectives. New measures and methodologies for studying time perspective and aging are also discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Roadmapping is an effective methodology to identify and link technology development and deployment efforts to a program's or project's needs and requirements. Roadmapping focuses on needed technical support to the baselines (and to alternatives to the baselines) where the probability of success is low (high uncertainty) and the consequences of failure are relatively high (high programmatic risk, higher cost, longer schedule, or higher ES and H risk). The roadmap identifies where emphasis is needed, i.e., areas where investments are large, the return on investment is high, or the timing is crucial. The development of a roadmap typically involves problem definition (current state versus the desired state) and major steps (functions) needed to reach the desired state. For Nuclear Materials (NM), the functions could include processing, packaging, storage, shipping, and/or final disposition of the material. Each function is examined to determine what technical development would be needed to make the function perform as desired. This requires a good understanding of the current state of technology and technology development and validation activities to ensure the viability of each step. In NM disposition projects, timing is crucial. Technology must be deployed within the project window to be of value. Roadmaps set the stage to keep the technology development and deployment focused on project milestones and ensure that the technologies are sufficiently mature when needed to mitigate project risk and meet project commitments. A recent roadmapping activity involved a 'cross-program' effort, which included NM programs, to address an area of significant concern to the Department of Energy (DOE) related to gas generation issues, particularly hydrogen. The roadmap that was developed defined major gas generation issues within the DOE complex and research that has been and is being conducted to address gas generation concerns. The roadmap also provided the basis for sharing

    To realize the life extension of nuclear power plants, overall evaluation for the plant is required, which covers technology, economy such as cost of repair or/and replacement of components, and regal regulations for licensing. A prototype of integrated assessment support system for life extension ''INPLEX'' have developed in order to evaluate the technical and economic issues relating to the plant life extension and to make a life extension scenario. Analysis procedure of INPLEX is as follows. A comparison of the cost between the life extension and the reconstruction is made to see whether the life extension is cost effective or not. Next, components required detailed assessments are selected, and the residual life assessment of these components are made. After those procedures life extension measures are selected and the implementation time schedule is set on the basis of the formulas for predicting the degradation of the components and the component reliability data. Finally the implementation time schedule is optimized from the viewpoint of economy, and the life extension scenario is proposed. INPLEX also has the data base ''PRINS'', in which information and data related to life extension are registered, such as component degradation experiences, degradation management methodologies, degradation mitigation measures, and so on. PRINS can be referred at any time during the operation of INPLEX

    This critical review presents several aspects related to the use of copper as a main component in brake pads in road vehicles. The compositions of these materials are attracting increasing interest and concern due to the relative contribution of wear products to particulate matter emissions in the environment as a result of braking action even though there has been a reduction in exhaust products from internal combustion engines. We review the data on the main wear mechanisms in brake systems and highlight the positive role of copper. However, similar to other heavy metal emissions, even the release of copper into the atmosphere may have important environmental and health effects. Thus, several replacement strategies are being pursued, and the positive and negative features will be critically reviewed. Additionally, the future perspectives in materials development will be discussed. - Highlights: • Copper in brake pad materials: role and concerns. • Environmental and health impact of copper. • Copper replacement in frictional brake materials. • International legislation and standards on the above issues. - Importance of copper in brake pad materials and concern as regards environmental and health impact of its emission as brake wear product.

    2012-01-01

    This qualitative study explored perspectives of emerging adult African American women on the development of mature love relationships. Inductive analysis of focus group interviews, conducted with a purposive sample of 31 African American women, yielded themes related to relationship goals and characteristics, and interpersonal and societal challenges to finding the right partner and developing a mature love relationship. Core categories that emerged from analysis of the discussions were (1) age and relationship goal differences within the emerging adult group, (2) mature love relationship goals and characteristics, (3) interpersonal obstacles to finding the right partner, and (4) societal obstacles to finding the right partner. Two approaches-black womanist/feminist thought (Collins, 2000 ; Walker, 1983 ) and relationship maturity theory (Paul & White, 1990 )-were then combined to explain the influence of historic and contemporary interpersonal and societal factors on developmental and ethnic issues that challenge positive gender identity formation, hasten intimacy maturity, and hinder the development of mature love relationships among emerging adult African American women. For these women, premature responsibility, especially early caregiver burden, was related to the early development of intimacy capacity and the desire for a mature love relationship, to be protected, and to have someone to help carry the load. Interracial dating, negative stereotypic images of African American women, and even positive images of enduring black love relationships posed difficult challenges to positive identity formation and intimacy maturity. A primary challenge was to counteract negative stereotypic images, so that they could develop their own self-identities as women and as relationship partners.

    potential yet. A growing national interest in local biodiversity as a natural resource is a welcome development on one hand, but the risk of too many restrictions for, e.g., the science community (high level of bureaucracy at all project stages from planning phase, visa procedures, field work permits, scientific exchange and project managment issues, governmental budget cuts for basic research and restricted access to international literature for Indonesian researchers does significantly hamper the internationalization of biodiversity-related science. In the long run, Indonesia has to find a balance between protectionism and sensible access to its national biodiversity to tackle global challenges in biodiversity conservation, health issues, food security, and climate change.

  14. Radioactive waste management issues related to the conversion of the Chernobyl sarcophagus into an ecologically safe system

    Rudy, C.G.; Vovk, I.F.

    1997-01-01

    The sarcophagus currently suffers from the extreme conditions in which it was hastily built, it may not last for 30 years, as was intended, and it may collapse earlier. Another cause of concern is the interaction of fuel-containing masses with water percolating into the shelter, possibly leading to migration and accumulation of fissile materials which, in turn, may result in reaching the state of criticality. The consistency of nuclear fuel debris is changing with time, and the monitoring and safety systems are deteriorating. With the increasing uncertainties of the data acquired, the confidence of any prediction is very low. The collapse of the sarcophagus would lead to a new radioactive contamination of the territory, groundwater and rivers. Thus, its conversion into an ecologically safe system is a pressing problem. The Gordian knot of the problem is to maintain safe management of a huge amount of messy radioactive waste both inside and outside the sarcophagus. The purpose of this paper is to discuss the issue in the light of the prospects for conversion of the sarcophagus and related activities currently being undertaken or planned in Ukraine

    Moskowitz, P.D.

    1992-01-01

    This paper examines environmental, health and safety issues associated with the production and use of CdTe photovoltaic modules. Handling of Cd and Te in photovoltaic production can present hazards to health, safety and the environment. Prior recognition of these hazards can allow device manufacturers time to implement appropriate hazard management strategies. The most important health hazards are probably related to chronic low-level exposures to Cd, especially to workers in manufacturing facilities. Because of the long latency period associated with the development of health effects arising from such exposures, and the availability of environmental and biomonitoring protocols, such hazards can be monitored and controlled. The true hazard presented by CdTe is very uncertain because characterizations of its inherent biological toxicity are based on extrapolation of data from other Cd compounds. Technical and institutional mechanisms for the recycling of spent CdTe modules may be needed to ensure public acceptance of this material option and to eliminate expensive disposal costs. (author)

Only the time it takes to do so is in question. Depending upon the assumptions selected, this time period could range from a few centuries to hundreds of thousands of years considering only the inherent radiotoxicities. However, if it can be assumed that the spent fuel radioactivity emplaced in a waste repository is less than 1/10 as available for human assimilation than that in a uranium ore deposit, then even under the most pessimistic set of assumptions, the EPA criteria can be considered to be complied with. 24 refs., 5 figs., 2 tabs

    This study examines the residential experiences of Korean ethnic elders in affordable housing in the greater Chicago area, focusing on how patterns of social relationships that evolved around a geographical location and its urban infrastructure enabled the elders to achieve their desire for residential independence. Based on the theoretical concept of activity settings and social capital, the study suggests an integrated theoretical model where social capital is understood as an embedded asset of an activity setting. Methodologically, this study uses a combined method of qualitative interviews with 138 Korean elders in affordable housing in the greater Chicago area and a geographic analysis of their social relationships in order to present associations among social relationships, urban infrastructures, and the shared value of independence within their residential communities. The study findings indicate that the elders mobilized ethnic businesses, urban infrastructures, and the collective efficacy of groups to achieve the shared goal of maintaining residential independence. In each community, a cultural broker acted as an important bridge between the community of ethnic minorities and the larger social networks coexisting within the community boundary. The relational perspective as a potent ground for understanding and further solving the issues of aging and ethnicity is highlighted.

    In implementing a national nuclear power program, balanced regulatory requirements are necessary to ensure nuclear safety and cost competitive nuclear power, and to help gain public acceptance. However, this is difficult due to the technology-intensive nature of the nuclear regulatory requirements, the need to reflect evolving technology and the need for cooperation among multidisciplinary technical groups. This paper suggests approaches to development of balanced nuclear regulatory requirements in developing countries related to nuclear power plant safety, radiation protection and radioactive waste management along with key technical regulatory issues. It does not deal with economic or market regulation of electric utilities using nuclear power. It suggests that national regulatory requirements be developed using IAEA safety recommendations as guidelines and safety requirements of the supplier country as a main reference after careful planning, manpower buildup and thorough study of international and supplier country's regulations. Regulation making is not recommended before experienced manpower has been accumulated. With an option that the supplier country's regulations may be used in the interim, the lack of complete national regulatory requirements should not deter introduction of nuclear power in developing countries.

    According to the recent changes of working environments and socio-economical conditions, the proportion of working women are increasing in Japan. Characteristics of occupational workload and stress of Japanese working women are consistent with those in many industrialized countries except man-dominant culture. In this review we describe the history, current issues, and future research directions on occupational health of working women, especially focused on reproductive health, work-related musculo-skeletal disorders (WMSDs), and mental disorders. In the reproductive health survey, traditionally main concern was about pregnancy outcomes, then fecundity studies, such as time to pregnancy, became topics recently. Future research will be shifted to outcomes not only during pregnancy but also disorders of hormonal balance and climacterium or health conditions after menopause. WMSDs are reviewed on mainly gender difference and its causative factors. Historically, mental health of working women in Japan has focused on the job stress of nurses. We compare results with a lot of recent researches in Europe and U.S.A., where interaction between occupational stress and family roles were studied. It is not easy to predict the prospective status of female workers in Japan, but social, workplace and familial supports will enhance their health promotion.
