    Rezende, Pedro A. D.

    This article aims to share some major lessons learned from the pioneering experience in Brazil with the world's first full national implementation of universal electronic voting. Differing notions of security, and their "collateral entanglements", appear to play a key role and are contrasted in Brazil's pioneering electronic voting saga. After an introduction, we puzzle through what election security may mean. We elaborate on how technological innovations may affect the underlying risks, their nature, corrections and balance. Then we describe some ways in which innovations have been deployed and validated, and how the results are being perceived, before some closing remarks.

    1998-11-01

    Nutritional issues often complicate health care but are very important in HIV treatment where diet can play a strong role in drug absorption and effectiveness. A Canadian company has started a for-fee nutritional counseling service called Ultimate Balance. The nutritionists at Ultimate Balance require medical disclosure and extensive telephone interviews with patients, and also review patients' cases and medications. The nutritional guidance provided is controversial, because it is funded by a company that produces nutritional supplements, and counselors sometimes recommend those supplements. A personal experience with the nutritional counseling service is described. Contact information is provided. PMID:11365979

  8. Balancing Acts: Culture as Commodity Among Business Consultants

    Directory of Open Access Journals (Sweden)

    Elias Mellander

    2013-09-01

    Full Text Available In this article the authors intend to analyze how the concept of culture is packaged, sold and delivered as a commodity. It is based on an ethnographic study of a Swedish consultancy in the field of cross-cultural communication and the relationship between the company and its clients. The clients were primarily foreign executives working in Sweden or Swedish expatriates, preparing for life abroad. The significance of culture-as-commodity will be explored from the perspective of the company as well as its clients in order to shed light on how the concept of culture can be communicated and what happens to it in the process. The study shows how the company combines theoretical perspectives from anthropology and intercultural communication with the aim to deliver a complex yet accessible understanding of culture to its clients. The analysis shows that these perspectives both clash and synergize, creating contradictions as well as turning culture into an accessible and useful tool for clients. The authors argue that researchers in the field of applied cultural analysis can learn from the example put forth by the balancing act between these two perspectives on culture performed by the company. The authors conclude that although the commodification process reduces and simplifies the meaning(s of culture, the company still manages to put culture on the agenda, demonstrating to its clients how, why, and in what ways it matters to them.

  9. Nuclear security information: A balancing act between confidentiality and transparency

    International Nuclear Information System (INIS)

    Full text: Nuclear information security - the control of access to sensitive information as well as classification and control measures for nuclear security information - is one of the principles of nuclear security culture. On the other hand the genera l public should be aware, that security is a key consideration for nuclear plant operation and transports of nuclear material. The internet has influenced society and today in all areas access to information is quite easy and taken for granted. Nuclear security is no exception and general information about security is necessary. It is clear that details relating to sensitive security arrangements cannot be divulged to the general public but the release of appropriate information can be helpful in acquiring public confidence and support for nuclear security. The particular content and mode of disseminating this information is a balancing act between confidentiality and transparency. It may vary according to local and national circumstances, the particular public being addressed and prevailing circumstances and conditions. Taking up examples from the nuclear and the non-nuclear field, the paper will focus on some reflections on what could or should be observed, when giving information in sensitive areas and in particular on nuclear security matters. Reflections such as: When evaluating the pros and cons of a transparent policy in the field of nuclear security and trying to evaluate what information may be disclosed, we have to be aware, that we are acting in the delicate field of the nuclear discussion. Further our behaviour will be compared with the information policy in nuclear safety, where in general absolutely open information is applied. Information in general is spread by Medias. When entering in the information business. we have to understand and care about how the Medias work and behave. We have to decide who will enter in contact with the Medias and which information has to be given to whom, at what time and

  10. The Balanced Budget Act of 1997: its impact on U.S. teaching hospitals.

    Dickler, R; Shaw, G

    2000-05-16

    The Balanced Budget Act of 1997 had a profound impact on the financing and organization of many health care services. The Act disproportionately affected U.S. teaching hospitals, leading to substantial budget reductions in many institutions and the threat of cuts in major programs and services that teaching hospitals provide to communities. This paper examines the overall financial and organizational impact of the Balanced Budget Act on teaching hospitals and considers its effect on residency education. It also discusses to what degree the Balanced Budget Refinement Act of 1999 will mitigate these effects and posits other solutions to the serious financial issues facing teaching hospitals in the United States.

    The Salvation Army in the United States addresses its mission of serving suffering humanity in Christ's name through a structure that is classically hierarchical while emphasizing local control and autonomy. Programming, community alliances, staffing, and fundraising are local rather than national functions. An example is discussed--the National Branding Promise--where the national office has taken a lead. This has been in response to rapid changes in the media, especially electronic communication. The Salvation Army views its components as its customers and works continuously to adjust the balance between national and local operations. PMID:18551843

    Hepcidin is a peptide hormone that regulates iron homeostasis and acts as an antimicrobial peptide. It is expressed and secreted by a variety of cell types in response to iron loading and inflammation. Hepcidin mediates iron homeostasis by binding to the iron exporter ferroportin, inducing its internalization and degradation via activation of the protein kinase Jak2 and the subsequent phosphorylation of ferroportin. Here we have shown that hepcidin-activated Jak2 also phosphorylates the trans...

    Agriculture contributes about 14% of global greenhouse gases per year. Mitigation for the sector is high since abatement options are often cost neutral or even net-profit-positive. The EX-ACT (Ex-ante Appraisal Carbon-balance) tool was developed by three FAO divisions (TCA, TCI and ESA) and aims to measure the impact of agriculture on GHG emissions and carbon sequestration. It consists of a set of Microsoft Excel sheets into which the project designer inserts land use and management practices...

  18. The relationship between the Balanced Budget Act (BBA) and hospital profitability.

    Science.gov (United States)

    Younis, Mustafa Z

    2006-01-01

    The Balanced Budget Act of 1997 (BBA) reduced the payment for fees for service providers and reduced the subsidy paid by the government for teaching hospitals. Since the passage of such cost containment measures, debates regarding their impact on hospitals, graduate medical education, and access to health care were raised. The need to examine the effect of such payment reduction on hospital profitability was widely ignored. We examined the relationship between the BBA and hospital profitability by using return on assets to measure profitability, by running an ordinary least squares regression for 1996 as pre-BBA and 1999 as post-BBA. We controlled for variables that were not included in previous literature, such as disproportionate share hospital status, critical access hospital status, and graduate medical education, measured by teaching hospitals to measure the effect of BBA cuts on teaching hospitals. Furthermore we incorporated several economic, financial, and utilization variables in the model. We used 1996 and 1999 data in our analysis to bridge potential effects of the BBA. To locate hospitals that changed ownership status we cross-matched the Medicare Cost Report data with the American Hospital Association Annual Survey. We found that overall hospital profitability declined as a result of the introduction of the BBA; however, small rural hospitals that converted to critical access status enjoyed improvement in financial status over the period of our study. Hospitals that converted to for-profit status did not improve in financial status, and showed a lower earning after the conversation. Our results show that the BBA had a negative effect on hospitals because of cuts in its reimbursement policy, except for critical access hospitals, which show improvement because of their exemption from the prospective payment system. Our study differs from others by using national comprehensive data for years that focus exclusively on the Balanced Budget Act period. We

    放牧管理者面临的挑战是如何平衡家畜生产与草地的其他价值,这些价值包括野生动物资源以及那些感觉不到的其他方面的价值.许多的这些价值受到放牧管理的影响,放牧后植物的残留数量是十分重要的.植物残留物增加枯枝落叶库的大小,对草地生态系统有重要作用.枯枝落叶影响植物生长和群落结构,进而影响食草动物.或许,重要的一点是枯枝落叶使得系统稳定,促进生产循环.因此,需要寻找植物被移走和保留之间的平衡,其结果可以通过家畜生产和生态系统的健康反映.%The challenge facing grazing managers is a balance livestock output with other values. Some values may include wildlife resources while others may be as intangible as a feeling of security in the knowledge that there will be forage for grazing next year. Many of these values are affected by grazing management through plant residue left after the grazing season. Plant residue is added to the litter pool which has significant impacts on the function of the grassland ecosystem. Litter affects plant growth and community structure. It affects herbivory. Perhaps most important, litter introduces stability into the production cycle. Therefore, the balancing act is between the amount of grass taken and the amount of grass left; the consequences are reflected in livestock output and health of the ecosystem.

    2012-11-01

    Full Text Available Abstract Proper repair of DNA double strand breaks (DSBs is vital for the preservation of genomic integrity. There are two main pathways that repair DSBs, Homologous recombination (HR and Non-homologous end-joining (NHEJ. HR is restricted to the S and G2 phases of the cell cycle due to the requirement for the sister chromatid as a template, while NHEJ is active throughout the cell cycle and does not rely on a template. The balance between both pathways is essential for genome stability and numerous assays have been developed to measure the efficiency of the two pathways. Several proteins are known to affect the balance between HR and NHEJ and the complexity of the break also plays a role. In this review we describe several repair assays to determine the efficiencies of both pathways. We discuss how disturbance of the balance between HR and NHEJ can lead to disease, but also how it can be exploited for cancer treatment.

    The nutrient balancing hypothesis proposes that, when sufficient food is available, the primary goal of animal diet selection is to obtain a nutritionally balanced diet. This hypothesis can be tested using the Geometric Framework for nutrition (GF). The GF enables researchers to study patterns of nutrient intake (e.g. macronutrients; protein, carbohydrates, fat), interactions between the different nutrients, and how an animal resolves the potential conflict between over-eating one or more nutrients and under-eating others during periods of dietary imbalance. Using the moose (Alces alces L.), a model species in the development of herbivore foraging theory, we conducted a feeding experiment guided by the GF, combining continuous observations of six captive moose with analysis of the macronutritional composition of foods. We identified the moose's self-selected macronutrient target by allowing them to compose a diet by mixing two nutritionally complementary pellet types plus limited access to Salix browse. Such periods of free choice were intermixed with periods when they were restricted to one of the two pellet types plus Salix browse. Our observations of food intake by moose given free choice lend support to the nutrient balancing hypothesis, as the moose combined the foods in specific proportions that provided a particular ratio and amount of macronutrients. When restricted to either of two diets comprising a single pellet type, the moose i) maintained a relatively stable intake of non-protein energy while allowing protein intakes to vary with food composition, and ii) increased their intake of the food item that most closely resembled the self-selected macronutrient intake from the free choice periods, namely Salix browse. We place our results in the context of the nutritional strategy of the moose, ruminant physiology and the categorization of food quality. PMID:26986618

    The application of the OPD-CA (Operationalised Psychodynamic Diagnostics in Childhood and Adolescence) for diagnostic purposes during the initial interview is no abdication of a psychoanalytic attitude. The study group OPD (2006, p. 289) proposed a "moderate structured action" for the investigation of the axes "interpersonal relations", "conflicts", "psychic structure", and "preconditions for treatment". But this is not a schematic checking. Space should be provided explicitly to a scenic development of the relationship-dynamics. In this article, the intersubjective character and the uniqueness of the conversation are underlined. Thus, the resulting diagnosis cannot be seen independently of the inner attitude and the concrete intervention of the interviewer. Certain phases of the interview that regularly ensue on the basis of the inherent dynamics and the "choreography" of a first meeting with a patient, are described in regard to the dynamic aspects and their significance in the OPD-Diagnostics. They are balanced with scenic points of view. Possible difficulties and suggestions for the practical handling are discussed on the basis of a case vignette. PMID:21381385

    Peroxisome proliferator-activated receptor-gamma (PPAR-γ) belongs to the nuclear hormone receptor superfamily. Apart from being involved in lipid metabolism, like its other subtypes PPAR α and β, it is implicated to be crucial for successful placentation. While its role in extravillous trophoblast (EVT) differentiation has been studied, the involvement in villous trophoblast (VT) differentiation, fatty-acid metabolism, inflammatory responses, and oxidative pathways during pregnancy deserves more attention. PPAR-γ's potential role in balancing structural development and functional responsibilities at the maternal-fetal interface suggest a more central role for the receptor. The central role of PPAR-γ in pathways related to placental pathologies suggests a potential role of PPAR-γ in placental function. The molecular regulation of PPAR-γ in this context has been widely disregarded. In this review, we discuss the less explored functions of PPAR-γ in the areas of immunological responses and management of oxidative stress in the placenta. We also shed light on the involvement of PPAR-γ in pathologic pregnancies and briefly discuss the current models in the field. The ability to modulate PPAR-γ's activity using already available drugs makes it a tempting therapeutic target. Elucidation of the molecular pathways and specific targets regulated by PPAR-γ will provide more information on the role of PPAR-γ in placentation and related disorders in pregnancy. Furthermore it will close the critical gap in our knowledge about the differential regulation of PPAR-γ in the two trophoblast lineages. This will help to evaluate the usefulness and timing of PPAR-γ modulation in at risk pregnancies to improve placental and endothelial function. PMID:25475254

  7. An Act of Balance Between Adaptive and Maladaptive Immunity in Depression: a Role for T Lymphocytes.

    Science.gov (United States)

    Toben, Catherine; Baune, Bernhard T

    2015-12-01

    Historically the monoaminergic neurotransmitter system, in particular the serotonergic system, was seen as being responsible for the pathophysiology of major depressive disorder (MDD). With the advent of psychoneuroimmunology an important role of the immune system in the interface between the central nervous systems (CNS) and peripheral organ systems has emerged. In addition to the well-characterised neurobiological activities of cytokines, T cell function in the context of depression has been neglected so far. In this review we will investigate the biological roles of T cells in depression. Originally it was thought that the adaptive immune arm including T lymphocytes was excluded from the CNS. It is now clear that peripheral naïve T cells not only carry out continuous surveillance within the brain but also maintain neural plasticity. Furthermore animal studies demonstrate that regulatory T lymphocytes can provide protection against maladaptive behavioural responses associated with depression. Psychogenic stress as a major inducer of depression can lead to transient trafficking of T lymphocytes into the brain stimulating the secretion of certain neurotrophic factors and cytokines. The separate and combined mechanism of CD4 and CD8 T cell activation is likely to determine the response pattern of CNS specific neurokines and neurotrophins. Under chronic stress-induced neuroinflammatory conditions associated with depression, T cell responses may become maladaptive and can be involved in neurodegeneration. Additionally, intracellular adhesion and MHC molecule expression as well as glucocorticoid receptor expression within the brain may play a role in determining T lymphocyte functionality in depression. Taken together, T lymphocyte mechanisms, which confer susceptibility or resilience to MDD, are not yet fully understood. Further insight into the cellular and molecular mechanisms which balance the adaptive and maladaptive roles of T lymphocytes may provide a better

    Despite an increase in advanced degrees awarded to women in the geosciences, scientific leaders in academia remain dominantly male. Women are underrepresented in tenure-track positions in Earth science departments at research universities and are less likely to have more senior positions within their academic institutions. Our empirical study analyzes factors that influence personal and professional success for women scientists. Prior research has shown that women are subjected to unintended and unrecognized biases that can have an ultimate impact on their productivity, advancement, and success. We used an electronic survey to collect data from 662 early-career geoscientists who are members of the Earth Science Women's Network and/or the network's Earth Science Jobs list. We asked respondents to self-report their perceptions of work/life balance, professional atmosphere and other variables indicative and/or predictive of personal and professional success. In a previous analysis (Kogan & Laursen, 2011) we found that women consistently rated the professional atmosphere in their departments and their interactions with colleagues less favorably than men. Women indicated lower rates of collaboration with colleagues in their unit compared to their male peers. We also found work/life balance is of particular concern to early-career scientists, especially since tenure clock and the biological clock function on similar timetables. Women reported more caregiving responsibilities than men, further complicating the balance between work and personal life. We hypothesize that the work life balance and professional atmosphere influences productivity, advancement, and career/job satisfaction. We now investigate how work/life balance, atmosphere within the work unit, and mentoring influence productivity, job and career satisfaction, and career advancement. We introduce a structural equation model that seeks to explain how these relationships vary dependent upon gender, career level

  19. The United States Revised Uniform Anatomical Gift Act (2006: New challenges to balancing patient rights and physician responsibilities

    2007-09-01

    Full Text Available Abstract Advance health care directives and informed consent remain the cornerstones of patients' right to self-determination regarding medical care and preferences at the end-of-life. However, the effectiveness and clinical applicability of advance health care directives to decision-making on the use of life support systems at the end-of-life is questionable. The Uniform Anatomical Gift Act (UAGA has been revised in 2006 to permit the use of life support systems at or near death for the purpose of maximizing procurement opportunities of organs medically suitable for transplantation. Some states have enacted the Revised UAGA (2006 and a few of those have included amendments while attempting to preserve the uniformity of the revised Act. Other states have introduced the Revised UAGA (2006 for legislation and remaining states are likely to follow soon. The Revised UAGA (2006 poses challenges to the Patient Self Determination Act (PSDA embodied in advance health care directives and individual expression about the use of life support systems at the end-of-life. The challenges are predicated on the UAGA revising the default choice to presumption of donation intent and the use of life support systems to ensure medical suitability of organs for transplantation. The default choice trumps the expressed intent in an individual's advance health care directive to withhold and/or withdraw life support systems at the end-of-life. The Revised UAGA (2006 overrides advance directives on utilitarian grounds, which is a serious ethical challenge to society. The subtle progression of the Revised UAGA (2006 towards the presumption about how to dispose of one's organs at death can pave the way for an affirmative "duty to donate". There are at least two steps required to resolve these challenges. First, physicians and hospitals must fulfill their responsibilities to educate patients on the new legislations and document their preferences about the use of life support

    thousands of US high schools that integrate climate science and solutions in a way that inspires and informs youth, and similar programs exist internationally. Other approaches to prepare vulnerable communities, especially young people, for natural hazards and human-induced environmental change include programs such as Plan International's "Child Centered Disaster Risk Reduction- Building Resilience Through Participation," and their "Weathering the Storm" project, focusing on integrating the needs of teenage girls with climate change adaptation and risk reduction. While minimizing global environmental and climate change is crucial, these and related programs that weave research with education, science with solutions offer the potential for addressing the "Grand Challenges" by better preparing for societal and environmental tipping points through a more balanced and integrated approach to addressing change."

  1. Balancing acts: A mixed methods study of the figured world of African American 7th graders in urban science classrooms

    Science.gov (United States)

    Cleveland-Solomon, Tanya E.

    What beliefs and cultural models do youth who are underrepresented in science have about the domain of science and about themselves as science learners? What do they imagine is possible for them in relation to science both now and in the future? In other words, what constitutes their figured world of science? This dissertation study, using a mixed methods design, offers new perspectives on the ways that underrepresented youth's unexamined assumptions or cultural models and resources may shape their identities and motivation to learn science. Through analyses of survey and interview data, I found that urban African American youths' social context, gender, racial identity, and perceptions of the science they had in school influenced their motivation to learn science. Analyses of short-term classroom observations and interviews suggested that students had competing cultural models that they used in their constructions of identities as science learners, which they espoused and adopted in relation to how well they leveraged the science-related cultural resources available to them. Results from this study suggested that these 7th graders would benefit from access to more expansive cultural models through access to individuals with scientific capital as a way to allow them to create fruitful identities as science learners. If we want to ensure that students from groups that are underrepresented in science not only have better outcomes, but aspire to and enter the science career pipeline, we must also begin to support them in their negotiations of competing cultural models that limit their ability to adopt science-learner identities in their classrooms. This study endeavored to understand the particular cultural models and motivational beliefs that drive students to act, and what types of individuals they imagine scientists and science workers to be. This study also examined how cultural models and resources influence identity negotiation, specifically the roles youths

  5. Thinking globally and acting locally in Mindanao: Supporting the delicate balance of future sustainability in South-East Asian wilderness as well as rural areas

    International Nuclear Information System (INIS)

    Although models of future sustainability often talk about effectively balancing economic, social and environmental imperatives or factors, in practice this typically remains an elusive ideal. This paper explores the exemplary possibilities but also dilemmas of a proposed initiative in the resource-rich but under-developed Filippino island province of Mindanao to achieve such a delicate balance in practice. This initiative by Raintrust Sustainable Ventures' proposes to link foreign investment in agricultural development to both the social advancement of local tribal peoples and the protection of large amounts of remaining wilderness areas. Such a case study provides an exemplary basis for discussing the challenge of achieving social and environmental as well as economic domains of 'future sustainability'. The crucial supporting role of information and geospatial technologies in the Raintrust plan will also be discussed

    Family therapists have a unique opportunity to contribute toward the reduction of widespread mental health disparities impacting diverse populations by developing applied lines of research focused on cultural adaptation. For example, although evidence-based prevention parent training (PT) interventions have been found to be efficacious with various Euro-American populations, there is a pressing need to understand which specific components of PT interventions are perceived by ethnic minority parents as having the highest impact on their parenting practices. Equally important is to examine the perceived cultural relevance of adapted PT interventions. This qualitative investigation had the primary objective of comparing and contrasting the perceived relevance of two culturally adapted versions of the efficacious parenting intervention known as Parent Management Training, the Oregon Model (PMTO). According to feasibility indicators provided by 112 Latino/a immigrant parents, as well as findings from a qualitative thematic analysis, the core parenting components across both adapted interventions were identified by the majority of research participants as relevant to their parenting practices. Participants exposed to the culturally enhanced intervention, which included culture-specific sessions, also reported high satisfaction with components exclusively focused on cultural issues that directly impact their parenting practices (e.g., immigration challenges, biculturalism). This investigation illustrates the relevant contributions that family therapy scholars can offer toward addressing mental health disparities, particularly as it refers to developing community-based prevention interventions that achieve a balance between evidence-based knowledge and cultural relevance.

  8. Evolution of the National All Schedules Prescription Electronic Reporting Act (NASPER): a public law for balancing treatment of pain and drug abuse and diversion.

    Science.gov (United States)

    Manchikanti, Laxmaiah; Whitfield, Ed; Pallone, Frank

    2005-10-01

    In the United States, physicians are faced with two opposing dilemmas in the treatment of pain - the potential for drug abuse and diversion, and the possible undertreatment of pain. While controlled prescription drugs such as narcotic analgesics, anxiolytics, antidepressants, stimulants, and sedative-hypnotics, play a legitimate role in managing chronic pain and other conditions, the illicit use of prescribed medicines is increasing at epidemic proportions. Diversion and abuse of prescription drugs is costly in terms of addiction, overdose, death, and related criminal activities, but chronic pain carries significant economic, social, and health impact as well. The American Society of Interventional Pain Physicians (ASIPP), as the introducing organization, was joined by several physician and nurse practitioner organizations in support of the National All Schedules Prescription Electronic Reporting (NASPER) Act of 2005, legislation that not only will give physicians an information tool to aid in prescribing controlled substances but also will help identify illicit use and abuse. NASPER is the law that provides for the establishment of a controlled substances monitoring program in each state. The concept for NASPER originated with ASIPP and was modeled after the highly successful Kentucky All Schedules Prescription Electronic Reporting Program (KASPER). Legislation was introduced in the United States House of Representatives during three different Congresses, the 107th, 108th, and 109th, by Reps. Edward Whitfield (R-KY) and Frank Pallone (D-NJ). It was first introduced in the United States Senate in the 107th Congress by Sen. Tim Hutchinson (R-AK), and in the 108th and 109th by Sens. Jeff Sessions (R-AL) and Dick Durbin (D-IL), with multiple cosponsors in both chambers. NASPER passed the House on July 27, 2005, by voice vote and passed the Senate by unanimous consent on July 29, 2005. President George W. Bush signed NASPER on August 11, 2005, and it became Public Law

  11. Managing industrial price risk: a balancing act

    International Nuclear Information System (INIS)

    The challenge of managing industrial price risk is assessed by a senior executive of Cargill, a diversified industrial conglomerate, involved in steel manufacturing and recycling, oilseeds, cocoa, beef, pork, and poultry processing, fertilizer and fruit juice production, in addition to trading and financial risk management. Energy is a key component in many of Cargill's businesses, hence the company has good reason to be concerned about price volatility. The effects of energy risk management on the company's shareholders are demonstrated by an analysis of month-to-month price fluctuations over the Nov 1999 to Oct 2000 period, showing the monthly value of risk at the 95 per cent confidence level as $4,832,195. The effects of alternatives for an end-user such as passing on cost to customers, improving energy efficiency. fuel switching and production curtailment, are explored and limitations and problems with each of the approaches are discussed. The best options for industrial end-users of natural gas are suggested to be a proactive risk management program in the short-term and asset diversification, fuel switching, and geographic relocation of production facilities in the long-term

    The abundance of ribonucleotides in DNA remained undetected until recently because they are efficiently removed by the ribonucleotide excision repair (RER) pathway, a process similar to Okazaki fragment (OF) processing after incision by Ribonuclease H2 (RNase H2). All DNA polymerases incorporate ribonucleotides during DNA synthesis. How many, when, and why they are incorporated has been the focus of intense work during recent years by many labs. In this review, we discuss recent advances in ribonucleotide incorporation by eukaryotic DNA polymerases that suggest an evolutionarily conserved role for ribonucleotides in DNA. We also review the data that indicate that removal of ribonucleotides has an important role in maintaining genome stability. PMID:26996833

    2014-01-01

    The four-cylinder U-shaped transmission mechanism is the core component of the output power of the Stirling engine. The rationality of its design is closely related to its operational stability, efficiency and life of the Stirling engine system. Based on the characteristics of the four cylinder U-shaped drive mechanism, this paper built the theoretical model of the dynamic balance analysis of the transmission mechanism in order to get the quality and the phase of the balance weight on the rotation axis. Then the dynamics simulation model of the four-cylinder doub-le-acting Stirling engine transmission mechanism was established through use of the multi-body dynamics simulation platform. In order to get a more realistic simulation of the crankshaft's actual operation conditions, this thesis estab-lished the crankshaft equivalent model with the dummy and universal hinge connection method, and the sliding bearing supported equivalent model with the virtual film method. The analysis results indicate that, compared with the original transmission mechanism model, the speed fluctuation coefficients of the output shaft and the crankshaft with the improved model are reduced by 11.5%, 36.8%and 34.4%, respectively;the vibration displacement of the center mass of the output shaft is decreased by 20.0%; the average dynamic load on the airframe is decreased by 23. 4%. The feasibility and effectiveness of the improvement program in this thesis has been verified, and as a result it can provide useful information for the design and operation of the Stirling engine's transmission mechanism.%四缸U型传动机构是斯特林发动机输出功率的核心部件,其设计的合理与否直接与斯特林发动机系统运行的稳定性、效率、寿命密切相关。基于四缸U型传动机构的特点,建立了传动机构动平衡配重的理论模型,获得了曲轴及输出轴上配重的质量和相位;进而基于多体动力学仿真平台,建立了4缸双作用斯

    2014-04-01

    balance group are in the initial phases of the design and construction of a watt balance and their paper provides valuable information on the design that they are building. The design of the main magnet of a watt balance is critical to its successful operation, and an important assumption of watt balance operation is that the field of the magnet in moving mode is equivalent to that in weighing mode. Sutton and Clarkson from MSL describe a novel magnet which is designed to address this issue. The international prototype of the kilogram is kept in air but, after redefinition, the best realizations of the mass unit will be in vacuum. In their paper Berry and Davidson from NPL describe progress in techniques which relate mass measured in vacuum to that measured in air. Such techniques will be essential for making the results of watt and joule balance measurements available to science and industry. Both the NIST and NPL Mark II (NRC) watt balances use knife edges to act as the pivots for the beam. Knife edges suffer from hysteresis which can produce systematic offsets during weighing. In their paper Choi (KRISS) and Robinson (NPL) describe the analysis of this problem using both finite element (FEM) techniques and a stand-alone balance designed for testing knife edges. The last two papers deal with the possible future of the watt balance technique. The BIPM simultaneous measurement scheme for the watt balance was originally conceived for operation at cryogenic temperatures with a superconducting coil. In their paper de Mirandes and her co-authors describe initial work on the principles of this superconducting variant of the BIPM watt balance and concentrate on the characteristics of the superconducting coil in comparison with those of a normal coil. The final paper is a good example of serendipity in which Kibble (Independent Consultant) was designing novel watt balances based on seismometer suspensions and Robinson (NPL) had derived a set of general expressions, which are

    Full Text Available [english] Goals: The increasing number of vacant positions for doctors increasingly puts the issue of reconciling work and family into the spotlight in companies, hospitals and universities, as increased expectations of a better work-life balance are seen as one of the reasons for these vacancies. Highly qualified professionals are trained, but not available to the labour market. The aim is to summarise what difficulties doctors who want to have a family and their potential employers must face.Methods: The following articles show the current state of research and potential starting points for an optimisation of the medical profession from a family-friendly perspective and intend to stimulate debate.Results: Some basic steps towards better work-life balance have already been taken, such as the provision of childcare places and the increasing availability of more flexible working patterns. But it seems that these measures, since they have been implemented neither sufficiently nor universally, do not suffice to secure the next generation of staff. Especially women in leadership positions are still rare to find.Conclusions: Both male and female doctors want better quality of life by achieving a better work-life balance. The expansion of family-friendly services is seen as a necessary step to allow female doctors to successfully combine work and family.[german] Zielsetzung: Die zunehmende Zahl unbesetzter Arztstellen lässt die Vereinbarkeit von Beruf und Familie zunehmend in den Fokus von Unternehmen, Kliniken und Universitäten rücken, da die gestiegenen Erwartungen an Work-Life-Balance als einer der Gründe hierfür anzusehen sind.

  12. Point configurations that are asymmetric yet balanced

    CERN Document Server

    Cohn, Henry; Kumar, Abhinav; Schuermann, Achill

    2008-01-01

    A configuration of particles confined to a sphere is balanced if they are in equilibrium under all force laws (that act between pairs of points with strength given by a fixed function of distance). It is straightforward to show that every sufficiently symmetrical configuration is balanced, but the converse is far from obvious. In 1957 Leech completely classified the balanced configurations in R^3, and his classification is equivalent to the converse for R^3. In this paper we disprove the converse in high dimensions. We construct several counterexamples, including one with trivial symmetry group.

    1977-01-01

    The water balance of the Skylab crew was analyzed. Evaporative water loss using a whole body input/output balance equation, water, body tissue, and energy balance was analyzed. The approach utilizes the results of several major Skylab medical experiments. Subsystems were designed for the use of the software necessary for the analysis. A partitional water balance that graphically depicts the changes due to water intake is presented. The energy balance analysis determines the net available energy to the individual crewman during any period. The balances produce a visual description of the total change of a particular body component during the course of the mission. The information is salvaged from metabolic balance data if certain techniques are used to reduce errors inherent in the balance method.

  7. Mass balance myths

    International Nuclear Information System (INIS)

    In the event of an oil spill at sea, remediation technologies rely on oil spill monitoring and mass balance calculations. The types of oil spills that require knowledge of mass-balance include weathering studies, dispersant-effectiveness testing, measurement of response effectiveness and damage assessment. Non-destructive and non-interfering measuring methods are needed to find components of the mass balance equation such as temporal and spatial distribution of the oil thickness, and the temporal and spatial distribution of oil concentration in the sub-surface plume. The main challenge is the variation in the size scale of laboratory and open ocean measurements. Most large scale oil-spill experiments do not have scientific credibility because there are few situations in which all the oil in the system is accounted for. While some components are accurately accounted for, others ignore mass balance, or the range of measurements is not sufficient to allow for computation of mass balance. 48 refs

  19. Load Balancing Scientific Applications

    Energy Technology Data Exchange (ETDEWEB)

    Pearce, Olga Tkachyshyn [Texas A & M Univ., College Station, TX (United States)

    2014-12-01

    The largest supercomputers have millions of independent processors, and concurrency levels are rapidly increasing. For ideal efficiency, developers of the simulations that run on these machines must ensure that computational work is evenly balanced among processors. Assigning work evenly is challenging because many large modern parallel codes simulate behavior of physical systems that evolve over time, and their workloads change over time. Furthermore, the cost of imbalanced load increases with scale because most large-scale scientific simulations today use a Single Program Multiple Data (SPMD) parallel programming model, and an increasing number of processors will wait for the slowest one at the synchronization points. To address load imbalance, many large-scale parallel applications use dynamic load balance algorithms to redistribute work evenly. The research objective of this dissertation is to develop methods to decide when and how to load balance the application, and to balance it effectively and affordably. We measure and evaluate the computational load of the application, and develop strategies to decide when and how to correct the imbalance. Depending on the simulation, a fast, local load balance algorithm may be suitable, or a more sophisticated and expensive algorithm may be required. We developed a model for comparison of load balance algorithms for a specific state of the simulation that enables the selection of a balancing algorithm that will minimize overall runtime.

  12. Balanced Integrated Regulatory Oversight

    International Nuclear Information System (INIS)

    Reactor safety, protecting the public health and safety, and protecting the environment must always be the nuclear regulator's top priorities. Enabling the use of nuclear power for the benefit of society, while protecting the public and the environment requires the regulator to balance many factors. In addition, the regulator is only one part of the overall government that must consider many factors as it carries out its societal responsibilities. Some of the factors that must be balanced and the practical impacts on how the regulator carries out its responsibilities will be addressed. The first International Conference on Effective Regulatory Systems, held in Moscow, Russian Federation, in 2006, focused on safety and security challenges with a goal of improving regulatory effectiveness through cooperation and sharing of information and best practices. The challenge of meeting both safety and security objectives is one example of potentially competing programmes that must be balanced. Other balances that must be evaluated include the benefits of safety improvements compared to the cost of implementation, the use of deterministic and probabilistic approaches, communication openness balanced with the protection of information that could be used for detrimental purposes, and timeliness of regulatory decision making balanced with the need to perform quality work in support of oversight responsibilities. A balanced and integrated approach to regulatory oversight is vital to ensuring that the regulatory body remains effective in its mission to enable the use of nuclear power while protecting the public and the environment. This concept is applicable to nations beginning a nuclear programme as well as established and experienced regulatory bodies. (author)

    Ferris, Alice T.

    1995-05-01

    A system for automatically calibrating force balances is provided. The invention uses a reference balance aligned with the balance being calibrated to provide superior accuracy while minimizing the time required to complete the calibration. The reference balance and the test balance are rigidly attached together with closely aligned moment centers. Loads placed on the system equally effect each balance, and the differences in the readings of the two balances can be used to generate the calibration matrix for the test balance. Since the accuracy of the test calibration is determined by the accuracy of the reference balance and current technology allows for reference balances to be calibrated to within +/-0.05% the entire system has an accuracy of +/-0.2%. The entire apparatus is relatively small and can be mounted on a movable base for easy transport between test locations. The system can also accept a wide variety of reference balances, thus allowing calibration under diverse load and size requirements.

    OpenAIRE

    2011-01-01

    Globalisation has affected the relationship between the trade balance and the real exchange rate in two ways. On the one hand, the growth of trade taking place within industries makes the trade balance more sensitive to real exchange movements. On the other hand, a higher degree of vertical specialisation and more global supply chains act to reduce this sensitivity. The relative importance of these two effects varies across countries. According to the estimates presented in this article, chan...

  9. Computerized Techniques for Calibrating Pressure Balances

    Science.gov (United States)

    Simpson, D. I.

    1994-01-01

    Pressure balances are generally calibrated by the cross-floating technique, where the forces acting on two similar devices in hydrostatic equilibrium are compared. It is a skilled and time-consuming process which has not previously lent itself to significant automation; computers have mostly been used only to calculate results after measurements have been taken. The objective of the present work was to develop real-time computerized measurement techniques to ease the calibration task, which would fully integrate into a single package with versatile software for calculating and displaying results. The calibration process is now conducted by studying graphical computer displays which derive their inputs from differential-pressure transducers and capacitance or optical displacement sensors. The mass imbalance between oil-operated pressure balances is calculated by interpolating between changes in piston rate-of-fall. Differential-pressure transducers are used to estimate mass imbalances between gas-operated balances, and a quick in situ method for determining their sensitivity has been developed. The new techniques have been successfully applied to a variety of pressure balance designs and substantial reductions in calibration times have been achieved. Reduced levels of scatter have revealed small systematic differences between gauge and absolute modes of operation.

    International Nuclear Information System (INIS)

    Denmark's consumption of energy increased 1,6 % from 2000 to 2001, primarily due to the year 2001 being colder than the year 2000. The production of petroleum decreased from 2000 to 2001, the reason being an accident at the Gorm oil field. The production of renewable energy and natural gas, however, increased. The energy balances is an account of production, import and export, and consumption of energy. The consumption is presented for households and industry. In the energy balances the energy consumption is accounted as physical amounts as well as gross consumption. Also an account is made of the costs of energy in basis prices and in market prices, including calculation of excises on energy, CO2 and SO2. (ln)

  19. Simple Cell Balance Circuit

    Science.gov (United States)

    Johnson, Steven D.; Byers, Jerry W.; Martin, James A.

    2012-01-01

    A method has been developed for continuous cell voltage balancing for rechargeable batteries (e.g. lithium ion batteries). A resistor divider chain is provided that generates a set of voltages representing the ideal cell voltage (the voltage of each cell should be as if the cells were perfectly balanced). An operational amplifier circuit with an added current buffer stage generates the ideal voltage with a very high degree of accuracy, using the concept of negative feedback. The ideal voltages are each connected to the corresponding cell through a current- limiting resistance. Over time, having the cell connected to the ideal voltage provides a balancing current that moves the cell voltage very close to that ideal level. In effect, it adjusts the current of each cell during charging, discharging, and standby periods to force the cell voltages to be equal to the ideal voltages generated by the resistor divider. The device also includes solid-state switches that disconnect the circuit from the battery so that it will not discharge the battery during storage. This solution requires relatively few parts and is, therefore, of lower cost and of increased reliability due to the fewer failure modes. Additionally, this design uses very little power. A preliminary model predicts a power usage of 0.18 W for an 8-cell battery. This approach is applicable to a wide range of battery capacities and voltages.

    2016-01-01

    This chapter focuses on one of the most common types of neurologic disorders: altered walking. Walking impairment often reflects disease of the neurologic structures mediating gait, balance or, most often, both. These structures are distributed along the neuraxis. For this reason, this chapter is introduced by a brief description of the neurobiologic underpinning of walking, stressing information that is critical for imaging, namely, the anatomic representation of gait and balance mechanisms. This background is essential not only in order to direct the relevant imaging tools to the regions more likely to be affected but also to interpret correctly imaging findings that may not be related to the walking deficit object of clinical study. The chapter closes with a discussion on how to image some of the most frequent etiologies causing gait or balance impairment. However, it focuses on syndromes not already discussed in other chapters of this volume, such as Parkinson's disease and other movement disorders, already discussed in Chapter 48, or cerebellar ataxia, in Chapter 23, in the previous volume. As regards vascular disease, the spastic hemiplegia most characteristic of brain disease needs little discussion, while the less well-understood effects of microvascular disease are extensively reviewed here, together with the imaging approach.

    Lesson "Balance in Nature" This simulation game-lesson (Balance in Nature) gives an opportunity for the students to show creativity, work independently, and to create models and ideas. It creates future-oriented thought connected to their experience, allowing them to propose solutions for global problems and personal responsibility for their activities. The class is divided in two teams. Each team chooses questions. 1. Question: Pollution in the environment. 2. Question: Care for nature and climate. The teams work on the chosen tasks. They make drafts, notes and formulate their solutions on small pieces of paper, explaining the impact on nature and society. They express their points of view using many different opinions. This generates alternative thoughts and results in creative solutions. With the new knowledge and positive behaviour defined, everybody realizes that they can do something positive towards nature and climate problems and the importance of individuals for solving global problems is evident. Our main goal is to recover the ecological balance, and everybody explains his or her own well-grounded opinions. In this work process the students obtain knowledge, skills and more responsible behaviour. This process, based on his or her own experience, dialogue and teamwork, helps the participant's self-development. Making the model "human↔ nature" expresses how human activities impact the natural Earth and how these impacts in turn affect society. Taking personal responsibility, we can reduce global warming and help the Earth. By helping nature we help ourselves. Teacher: Veselina Boycheva-Chapanova " Saint Patriarch Evtimii" Scholl Str.

  5. Watt and joule balances

    Science.gov (United States)

    Robinson, Ian A.

    2014-04-01

    The time is fast approaching when the SI unit of mass will cease to be based on a single material artefact and will instead be based upon the defined value of a fundamental constant—the Planck constant—h . This change requires that techniques exist both to determine the appropriate value to be assigned to the constant, and to measure mass in terms of the redefined unit. It is important to ensure that these techniques are accurate and reliable to allow full advantage to be taken of the stability and universality provided by the new definition and to guarantee the continuity of the world's mass measurements, which can affect the measurement of many other quantities such as energy and force. Up to now, efforts to provide the basis for such a redefinition of the kilogram were mainly concerned with resolving the discrepancies between individual implementations of the two principal techniques: the x-ray crystal density (XRCD) method [1] and the watt and joule balance methods which are the subject of this special issue. The first three papers report results from the NRC and NIST watt balance groups and the NIM joule balance group. The result from the NRC (formerly the NPL Mk II) watt balance is the first to be reported with a relative standard uncertainty below 2 × 10-8 and the NIST result has a relative standard uncertainty below 5 × 10-8. Both results are shown in figure 1 along with some previous results; the result from the NIM group is not shown on the plot but has a relative uncertainty of 8.9 × 10-6 and is consistent with all the results shown. The Consultative Committee for Mass and Related Quantities (CCM) in its meeting in 2013 produced a resolution [2] which set out the requirements for the number, type and quality of results intended to support the redefinition of the kilogram and required that there should be agreement between them. These results from NRC, NIST and the IAC may be considered to meet these requirements and are likely to be widely debated

    MAO Yibo

    2003-01-01

    The discrete scalar data need prefiltering when transformed by discrete multi-wavelet, but prefiltering will make some properties of multi-wavelets lost. Balanced multi-wavelets can avoid prefiltering. The sufficient and necessary condition of p-order balance for multi-wavelets in time domain, the interrelation between balance order and approximation order and the sampling property of balanced multi-wavelets are investigated. The algorithms of 1-0rder and 2-0rder balancing for multi-wavelets are obtained. The two algorithms both preserve the orthogonal relation between multi-scaling function and multi-wavelets. More importantly, balancing operation doesn't increase the length of filters, which suggests that a relatively short balanced multiwavelet can be constructed from an existing unbalanced multi-wavelet as short as possible.

  11. Force Density Balance inside the Hydrogen Atom

    CERN Document Server

    Himpsel, F J

    2015-01-01

    Motivated by the long-debated question about the internal stability of the electron, the force densities acting on the charge density of the 1s electron in the H atom are investigated. The problem is mapped onto the canonical formalism for a classical Dirac field coupled to the electric field of an external point charge. An explicit calculation shows that the attractive Coulomb force density is balanced exactly at every point in space by the repulsive confinement force density. The latter requires evaluating the divergence of the stress tensor for the 1s solution of the Dirac equation. Such a local force balance goes beyond the global stability criteria that are usually given for the H atom. This concept is extended to the internal stability of any charged particle by investigating the force densities acting on its surrounding vacuum polarization. At large distances one has to consider only the charge density of virtual electrons and positrons, induced by a point charge in the vacuum of quantum electrodynamic...

However, a formal, evolutionary genetic theory of social cheating that provides an explanatory, predictive framework for these observations is lacking. Here we derive the kin...... selection-mutation balance, which provides an evolutionary null hypothesis for the statics and dynamics of cheating. When social interactions have linear fitness effects and Hamilton´s rule is satisfied, selection is never strong enough to eliminate recurrent cheater mutants from a population, but cheater...... lineages are transient and do not invade. Instead, cheating lineages are eliminated by kin selection but are constantly reintroduced by mutation, maintaining a stable equilibrium frequency of cheaters. The presence of cheaters at equilibrium creates a "cheater load" that selects for mechanisms of cheater...

    An introductory survey of the global energy balance climate models is presented with an emphasis on analytical results. A sequence of increasingly complicated models involving ice cap and radiative feedback processes are solved, and the solutions and parameter sensitivities are studied. The model parameterizations are examined critically in light of many current uncertainties. A simple seasonal model is used to study the effects of changes in orbital elements on the temperature field. A linear stability theorem and a complete nonlinear stability analysis for the models are developed. Analytical solutions are also obtained for the linearized models driven by stochastic forcing elements. In this context the relation between natural fluctuation statistics and climate sensitivity is stressed.

  16. Gravity in the balance

    International Nuclear Information System (INIS)

    Although Einstein's theories of relativity showed that Newton's ideas about gravity, space and time were approximations, general relativity still predicts that the gravitational force between two point objects will obey an inverse-square law in the limit of low velocities and weak gravitational fields. Of course, we know that general relativity is probably an approximation as well and that some grander theory - possibly involving extra dimensions of space - will unify gravity with the other fundamental forces. Many of these theories predict that the inverse-square law will break down at distances that are becoming accessible to (relatively small) experiments with torsion balances. As researchers from the Eoet-Wash group in Seattle report 'Testing the gravitational inverse-square law', the inverse-square law has survived all tests so far, but its days are surely numbered.

    When multiple channels are employed in a pulse-Doppler radar, achieving and maintaining balance between the channels is problematic. In some circumstances the channels may be commutated to achieve adequate balance. Commutation is the switching, trading, toggling, or multiplexing of the channels between signal paths. Commutation allows modulating the imbalance energy away from the balanced energy in Doppler, where it can be mitigated with filtering.

  6. Paul Collier : Balancing beams

    2009-01-01

    As former head of AB Operations, Paul Collier and his group were in the ‘cockpit’ for the LHC’s maiden voyage - piloting the first beam around the ring. But now, as Head of the Beams Department, he will need his feet firmly on the ground in order to balance all the beam activities at CERN. "As Department Head, I’ll have less direct contact with the machines," Collier says with a hint of regret. "I’ll still obviously be very involved, but they won’t actually let me loose in front of the keyboard anymore!" As the new Head of the BE Department, Collier will be in charge of nearly 400 people, and will oversee all the beam activities, including the preparations for the longest period of beam operation in the history of CERN. In the new organization, the BE, TE and EN Departments have been grouped together in the Accelerator and Technology Sector. "‘Partnership’ is a key word for the three departments," says Collier.

  8. Balancing safety and economics

    International Nuclear Information System (INIS)

    The safety requirements of NPPs have always aimed at limiting societal risks. This risk approach initially resulted in deterministic design criteria and concepts. In the 1980s the paradigm 'safety at all costs' arose and often led to questionable backfitting measures. Conflicts between new requirements, classical design concepts and operational demands were often ignored. The design requirements for advanced reactors ensure enhanced protection against severe accidents. Still, it is questionable whether the 'no-damage-outside-the-fence' criteria can be achieved deterministically and at competitive costs. Market deregulation and utility privatisation call for a balance between safety and costs, without jeopardising basic safety concepts. An ideal approach must be risk-based and imply modern PSAs and new methods for cost-benefit and ALARA analyses, embed nuclear risks in a wider risk spectrum, but also make benefits transparent within the context of a broader life experience. Governments should define basic requirements, minimum standards and consistent comparison criteria, and strengthen operator responsibility. Internationally sufficient and binding safety requirements must be established and nuclear technology transfer handled in a responsible way, while existing plants, with their continuous backfitting investments, should receive particular attention.

  9. Par Pond water balance

    International Nuclear Information System (INIS)

    A water budget for the Par Pond hydrologic system was established in order to estimate the rate of groundwater influx to Par Pond. This estimate will be used in modeling exercises to predict Par Pond reservoir elevation and spillway discharge in the scenario where Savannah River water is no longer pumped and discharged into Par Pond. The principal of conservation of mass was used to develop the water budget, where water inflow was set equal to water outflow. Components of the water budget were identified, and the flux associated with each was determined. The water budget was considered balanced when inflow and outflow summed to zero. The results of this study suggest that Par Pond gains water from the groundwater system in the upper reaches of the reservoir, but looses water to the groundwater system near the dam. The rate of flux of groundwater from the water table aquifer into Par Pond was determined to be 13 cfs. The rate of flux from Par Pond to the water table aquifer near the dam was determined to be 7 cfs

    The open office is the dominant form of workspace design for good reason: It fosters collaboration, promotes learning, and nurtures strong culture. But what most companies fail to realize is that collaboration has a natural rhythm that requires both interaction and private contemplation. Companies have been trying for decades to find the balance between public and private workspace that best supports collaboration. In 1980 52% of U.S. employees lacked workspaces where they could concentrate without distraction. In response, high-walled cubicles took over the corporate landscape. By the late 1990s, the tide had turned, and only 23% of employees wanted more privacy, and 50% wanted more access to other people. Ever since, firms have been beefing up spaces that support collaboration and shrinking areas for individual work. But the pendulum seems to have swung too far: Once again, people feel a pressing need for privacy, not only to do heads-down work but to cope with the intensity of work today. To address these needs, according to the authors, we have to rethink our assumptions about privacy. Traditionally defined in physical terms, privacy is now about the individual's ability to control information and stimulation. In this article, the authors examine workspace design through the new lens of privacy and offer insights on how to foster teamwork and solitude. PMID:25509575

    2010-01-01

    Over the course of her career as a physicist, Felicitas Pauss, currently responsible for CERN's External Relations, has often been the sole woman in an environment dominated by men. While she freely admits that being a woman physicist can have as many advantages as disadvantages, she thinks the best strategy is to maintain the right balance.   From a very early age, Felicitas Pauss always wanted to be involved in projects that interested and fascinated her. That's how she came to study physics. When she was a first-year university student in Austria in 1970, it was still fairly uncommon for women to go into physics research. "I grew up in Salzburg with a background in music. At that time, it was certainly considered more ‘normal’ for a woman to study music than to do research in physics. But already in high school I was interested in physics and technical instruments and wanted to know how things work and what they are made of”. At the beginning of her care...

Further, PRDM2 acts upstream of the repressive PRC2 complex in G0. We identify...... a novel G0-specific bivalent chromatin domain in the CCNA2 locus. PRDM2 protein interacts with the PRC2 protein EZH2 and regulates its association with the bivalent domain in the CCNA2 gene. Our results suggest that induction of PRDM2 in G0 ensures that two antagonistic programs-myogenesis and the cell...

    Indirect speech acts are frequently used in verbal communication, the interpretation of them is of great importance in order to meet the demands of the development of students' communicative competence. This paper, therefore, intends to present Searle' s indirect speech acts and explore the way how indirect speech acts are interpreted in accordance with two influential theories. It consists of four parts. Part one gives a general introduction to the notion of speech acts theory. Part two makes an elaboration upon the conception of indirect speech act theory proposed by Searle and his supplement and development of illocutionary acts. Part three deals with the interpretation of indirect speech acts. Part four draws implication from the previous study and also serves as the conclusion of the dissertation.

  20. REVIEW ARTICLE: Multi-component force balances for conventional and cryogenic wind tunnels

    Science.gov (United States)

    Ewald, Bernd F. R.

    2000-06-01

    The measurement of the total forces acting on the surface of a wind tunnel model is still the most important wind tunnel measurement technology. Either the model is mounted by struts to a balance, which is located outside the test section (an `external balance'), or the balance is located inside the model and connects the model structure to the mounting sting, which in the case of aeroplane configurations protrudes from the rear fuselage (an `internal balance'). This review concerns internal balances only. The functional principle is described and some comments on the demand for high accuracy are given. The optimization of designs for strain gauge balances, the fabrication methods and the selection of materials are commented on. The calibration theory of multi-component balances is outlined and the calibration equipment is described. Examples for conventional manual calibration equipment and for an automatic calibration machine are given. Finally the specific design features of cryogenic balances and half model balances are given. This review presents the author's experiences and developments. Since there is hardly any general literature on the subject of strain gauge balances and since the balance engineers in the world have not that much contact with each other, there may be different points of view at other institutions.

  1. Calibration Variable Selection and Natural Zero Determination for Semispan and Canard Balances

    Science.gov (United States)

    Ulbrich, Norbert M.

    2013-01-01

    Independent calibration variables for the characterization of semispan and canard wind tunnel balances are discussed. It is shown that the variable selection for a semispan balance is determined by the location of the resultant normal and axial forces that act on the balance. These two forces are the first and second calibration variable. The pitching moment becomes the third calibration variable after the normal and axial forces are shifted to the pitch axis of the balance. Two geometric distances, i.e., the rolling and yawing moment arms, are the fourth and fifth calibration variable. They are traditionally substituted by corresponding moments to simplify the use of calibration data during a wind tunnel test. A canard balance is related to a semispan balance. It also only measures loads on one half of a lifting surface. However, the axial force and yawing moment are of no interest to users of a canard balance. Therefore, its calibration variable set is reduced to the normal force, pitching moment, and rolling moment. The combined load diagrams of the rolling and yawing moment for a semispan balance are discussed. They may be used to illustrate connections between the wind tunnel model geometry, the test section size, and the calibration load schedule. Then, methods are reviewed that may be used to obtain the natural zeros of a semispan or canard balance. In addition, characteristics of three semispan balance calibration rigs are discussed. Finally, basic requirements for a full characterization of a semispan balance are reviewed.

  4. Comments on "Towards Balanced Development in Pakistan".

    Science.gov (United States)

    Fitzgerald, E V

    1992-01-01

    Critical comment on the proposal of Professor Pyatt for balanced development in Pakistan focused on broad methodological issues. Professor Pyatt's approach proposes to balance efficiency criteria with longterm objectives of sustainable economic and human development: changing asset distribution through new investment and shifting investment returns in the social sector to households. I is a systematic attempt to compensate for deficits in human development. Policies would include "tariffisation of quota allocation of goods such as water, differential pricing to protect the poor; national conservation and polluter penalties; foreign aid shift to human maintenance expenditure; and reform of fiscal policy on income and expenditure to allow for support of social objectives." Patterns of property and institutional privilege can be effectively altered through market practices, such that wage goods could be subsidized in order to increase productivity. Constructive rethinking of assumptions underlying the balanced development argument is suggested, because of Pyatt model is contrary to the Dornbusch assumptions behind structural adjustment of the standard World Bank model. The assumption in question is that nontraditional expenditure on health, education, and the environment reduces unit labor costs. Concern is also raised about the approach to "efficiency wages" and the inputs of health and education, and food and housing, which are required to supply labor. Real wages might be conceptualized as affecting labor productivity in a more dynamic way than Professor Pyatt recognized. Use of human capital would be maximized and would be equivalent to the formation of new human capital. Wages may be construed to act like internal trade, where prices and markets are effectively interchanged so that farmers receive not only agricultural products, but also essential and nonessential consumer goods. Professor Pyatt's article is relevant to any country's development planning and

    1977-01-01

    Estimates of the precision of the net water balance were obtained for the entire Skylab preflight and inflight phases as well as for the first two weeks of flight. Quantitative estimates of both total sampling errors and instrumentation errors were obtained. It was shown that measurement error is minimal in comparison to biological variability and little can be gained from improvement in analytical accuracy. In addition, a propagation of error analysis demonstrated that total water balance error could be accounted for almost entirely by the errors associated with body mass changes. Errors due to interaction between terms in the water balance equation (covariances) represented less than 10% of the total error. Overall, the analysis provides evidence that daily measurements of body water changes obtained from the indirect balance technique are reasonable, precise, and relaible. The method is not biased toward net retention or loss.

  8. An Oscillating Magnet Watt Balance

    2015-01-01

    We establish the principles for a new generation of simplified and accurate watt balances in which an oscillating magnet generates Faraday's voltage in a stationary coil. A force measuring system and a mechanism providing vertical movements of the magnet are completely independent in an oscillating magnet watt balance. This remarkable feature allows to establish the link between the Planck constant and a macroscopic mass by a one single experiment. Weak dependence on variations of environmental and experimental conditions, weak sensitivity to ground vibrations and temperature changes, simple force measuring procedure, small sizes and other useful features offered by the novel approach considerably reduce the complexity of the experimental setup. We formulate the oscillating magnet watt balance principle and establish the measurement procedure for the Planck constant. We discuss the nature of oscillating magnet watt balance uncertainties and give a brief description of the National Metrology Institute (UME) wa...

    International Nuclear Information System (INIS)

    In 1988, a special Committee of the Rocky Mountain Mineral Law Foundation undertook a project to draft a model from gas balancing agreement. This project was initiated at the request of a number of Foundation members who felt that a model form gas balancing agreement would facilitate the negotiation of operating agreement, since gas balancing issues had become sticking points in the process. The Committee was composed of attorneys representing a wide cross-section of the oil and gas industry including both major and independent oil companies, production companies with interstate pipeline affiliates, and private practitioners. The Committee attempted to address the more controversial issues in gas balancing with optional provisions in the Form. To facilitate the negotiation process, the number of optional provisions was minimized. This form may be used as an Appendix to the new A.A.P.L. Form 610-1989 Model Form Operating Agreement. This book includes provision of this Form which are: Ownership of gas production; Balancing of production accounts; Cash balancing upon depletion; Deliverability tests; Nominations; Statements; Payment of taxes; Operating expenses; Overproducing allowable; Payment of leasehold burdens; Operator's liability; Successors and assigns; Audits; Arbitration; and Operator's fees

    This paper provided an outline of Canada's Clean Air Act and examined some of the regulatory changes that will occur as a result of its implementation. The Act is being introduced to strengthen the legislative basis for taking action on reducing air pollution and GHGs, and will allow the government to regulate both indoor and outdoor air pollutants and GHGs. The Act will require the Ministers of the Environment and Health to establish national air quality objectives, as well as to monitor and report on their attainment. The Canadian Environmental Protection Act will be amended to enable the government to regulate the blending of fuels and their components. The Motor Vehicle Fuel Consumption Standards Act will also be amended to enhance the government's authority to regulate vehicle fuel efficiency. The Energy Efficiency Act will also be expanded to allow the government to set energy efficiency standards and labelling requirements for a wider range of consumer and commercial products. The Act will commit to short, medium and long-term industrial air pollution targets. Regulations will be proposed for emissions from industry; on-road and off-road vehicles and engines; and consumer and commercial products. It was concluded that the Government of Canada will continue to consult with provinces, territories, industries and Canadians to set and reach targets for the reduction of both indoor and outdoor air pollutants and GHG emissions. 6 figs

As previously, the main responsibility for public radiation protection will rest with one central radiation protection authority. According to the 1988 Act, the general obligations with regard to radiation protection will place a greater responsibility than in the past on persons carrying out activities involving radiation. Under the act, it is possible to adjust the licensing and supervisory procedures to the level of danger of the radiation source and the need for adequate competence, etc. The Act recognises standardised approval procedures combined with technical regulations for areas where the risks are well known. The Act contains several rules providing for more effective supervision. The supervising authority may in particular decide on the necessary regulations and prohibitions for each individual case. The possibilities of using penal provisions have been extended and a rule on the mandatory execution of orders has been introduced. The Ordinance on Radiation Protection (1988:293) designates the National Institute of Radiation Protection (SSI) as the central authority referred to in the Radiation Protection Act. The book also gives a historic review of radiation protection laws in Sweden, lists regulations issued by SSI and presents explanations of radiation effects and international norms in the area.

    Søndergaard, Morten

    identify and locate the experiments of POEX65 as acts; and to ask the questions: what constitutes those acts as experiments? and how do we possibly archive them? My purpose, then, is to define the methodologies to obtain the contours of a post-phenomenology of experimental artistic production in order to...... be able to analyse the phenomena found at POEX65. Here I will use the notion of the ‘ontological theatre’ (Pickering), which, according to Pickering, is acted out in experimental art productions. The experiment could thus be seen as an ‘agency-realism’ – as an ‘act’ of relations across the aesthetics...

  6. Feedforward versus feedback modulation of human vestibular-evoked balance responses by visual self-motion information

    OpenAIRE

    Day, B. L.; Guerraz, M.

    2007-01-01

    Visual information modulates the balance response evoked by a pure vestibular perturbation (galvanic vestibular stimulation, GVS). Here we investigate two competing hypotheses underlying this visual-vestibular interaction. One hypothesis assumes vision acts in a feedforward manner by altering the weight of the vestibular channel of balance control. The other assumes vision acts in a feedback manner through shifts in the retinal image produced by the primary response. In the first experiment w...

  7. Dairy Proteins and Energy Balance

    DEFF Research Database (Denmark)

    Bendtsen, Line Quist

    High protein diets affect energy balance beneficially through decreased hunger, enhanced satiety and increased energy expenditure. Dairy products are a major source of protein. Dairy proteins are comprised of two classes, casein (80%) and whey proteins (20%), which are both of high quality, but...... casein is absorbed slowly and whey is absorbed rapidly. The present PhD study investigated the effects of total dairy proteins, whey, and casein, on energy balance and the mechanisms behind any differences in the effects of the specific proteins. The results do not support the hypothesis that dairy...... proteins, whey or casein are more beneficial than other protein sources in the regulation of energy balance, and suggest that dairy proteins, whey or casein seem to play only a minor role, if any, in the prevention and treatment of obesity....

  8. Constrained Allocation Flux Balance Analysis

    CERN Document Server

    Mori, Matteo; Martin, Olivier C; De Martino, Andrea; Marinari, Enzo

    2016-01-01

    New experimental results on bacterial growth inspire a novel top-down approach to study cell metabolism, combining mass balance and proteomic constraints to extend and complement Flux Balance Analysis. We introduce here Constrained Allocation Flux Balance Analysis, CAFBA, in which the biosynthetic costs associated to growth are accounted for in an effective way through a single additional genome-wide constraint. Its roots lie in the experimentally observed pattern of proteome allocation for metabolic functions, allowing to bridge regulation and metabolism in a transparent way under the principle of growth-rate maximization. We provide a simple method to solve CAFBA efficiently and propose an "ensemble averaging" procedure to account for unknown protein costs. Applying this approach to modeling E. coli metabolism, we find that, as the growth rate increases, CAFBA solutions cross over from respiratory, growth-yield maximizing states (preferred at slow growth) to fermentative states with carbon overflow (preferr...

    For the shallow-water equations on an equatorial beta plane, the properties of low-frequency Rossby waves and (mixed) Rossby-gravity waves are investigated. It is shown that in the low-frequency limit the horizontal divergence of these solutions is zero and their geopotential satisfies = f, where f = y is the Coriolis parameter and is the stream function of the non-divergent velocity field. This type of balance is rather different from the geostrophic balance satisfied by Kelvin waves. It can...

    Gawroński, P.; Kułakowski, K.

    2005-07-01

    Recently, a continuous dynamics was proposed to simulate dynamics of interpersonal relations in a society represented by a fully connected graph. The final state of such a society was found to be identical with the so-called Heider balance (HB), where the society is divided into two mutually hostile groups. In the continuous model, a polarization of opinions was found in HB. Here we demonstrate that the polarization occurs also in Barabási-Albert networks, where the Heider balance is not necessarily present. In the second part of this work we demonstrate the results of our formalism, when applied to reference examples: the Southern women and the Zachary club.

    Control of balance is complex and involves maintaining postures, facilitating movement, and recovering equilibrium. Balance control consists of controlling the body center of mass over its limits of stability.

  2. An Improved Hadoop Data Load Balancing Algorithm

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available Data load balancing is one of the key problems of big data technology. As a big data application, Hadoop has had many successful applications. HDFS is Hadoop Distributed File System and has the load balancing procedure which can balance the storage load on each machine. However, this method cannot balance the overload rack preferentially, and so it is likely to cause the breakdown of overload machines. In this paper, we focus on the overload machines and propose an improved algorithm for balancing the overload racks preferentially. The improved method constructs Prior Balance List list which includes overload machines, For Balance List list and NextForBalanceList list by many factors and balances among the racks selected from these lists firstly. Experiments show that the improved method can balance the overload racks in time and reduce the possibility of breakdown of these racks

  7. The CEO's second act.

    Science.gov (United States)

    Nadler, David A

    2007-01-01

    When a CEO leaves because of performance problems, the company typically recruits someone thought to be better equipped to fix what the departing executive couldn't--or wouldn't. The board places its confidence in the new person because of the present dilemma's similarity to some previous challenge that he or she dealt with successfully. But familiar problems are inevitably succeeded by less familiar ones, for which the specially selected CEO is not quite so qualified. More often than not, the experiences, skills, and temperament that yielded triumph in Act I turn out to be unequal to Act II's difficulties. In fact, the approaches that worked so brilliantly in Act I may be the very opposite of what is needed in Act II. The CEO has four choices: refuse to change, in which case he or she will be replaced; realize that the next act requires new skills and learn them; downsize or circumscribe his or her role to compensate for deficiencies; or line up a successor who is qualified to fill a role to which the incumbent's skills and interests are no longer suited. Hewlett-Packard's Carly Fiorina exemplifies the first alternative; Merrill Lynch's Stanley O'Neal the second; Google's Sergey Brin and Larry Page the third; and Quest Diagnostics' Ken Freeman the fourth. All but the first option are reasonable responses to the challenges presented in the second acts of most CEOs' tenures. And all but the first require a power of observation, a propensity for introspection, and a strain of humility that are rare in the ranks of the very people who need those qualities most. There are four essential steps executives can take to discern that they have entered new territory and to respond accordingly: recognition that their leadership style and approach are no longer working; acceptance of others' advice on why performance is faltering; analysis and understanding of the nature of the Act II shift; and, finally, decision and action.

    2009-01-01

    Careful assessment of the fluid balance is required in the perioperative period since appropriate fluid therapy is essential for successful patient's outcome. Haemodynamic monitoring allows understanding the physiology of the circulation and changes of fluid balance in the perioperative period. This is diagnostic aid and guide for fluid replacement therapy. Patient's volume status is frequently assessed by different haemodynamic variables that could be targeted as the endpoints for fluid therapy and resuscitation. Fluid balance is the crucial factor in the maintenance of haemodynamic stability, tissue oxygenation and organ function. When the haemodynamic monitoring is applied in a rigorous and consistent manner, it reduces mortality and length of stay as well as costs incurred. There are a number of tests which describe the effectiveness of the invasive haemodynamic monitoring procedures usage. Since the pulmonary artery catheter (PAC) had been introduced into clinical practice it was considered as a golden standard for cardiac output measurements, haemodynamic and fluid balance assessment. Nevertheless, in previous 10 years new minimally invasive and noninvasive simple techniques for haemodynamic monitoring and patient's hydroelectricity status evaluation have been developed. They can replace PAC under different clinical circumstances and some of these techniques PMID:19504992

  13. No 592 - Radiation Act

    International Nuclear Information System (INIS)

    This Act will enter into force on 1 January 1992. The scope of the Act is extensive as, in addition to ionizing radiation, it will also apply to activities involving exposure to natural radiation and non-ionizing radiation. Its purpose is to prevent and restrict harmful effects to health resulting from radiation. The basic principles of the Act are that the practice involving radiation should be justified; radiation protection should be optimized; and radiation doses should be as low as reasonably achievable. Licensed organisations using radiation will be responsible for the safety of the activity involving exposure to radiation and for having available the appropriate expertise to this effect. The required so-called safety licence provides the regulatory control to ensure that radiation is used sensibly, that the equipment and shields are technically acceptable and the operating personnel is competent, and that the radioactive waste is dealt with appropriately. The Radiation Act will also apply to nuclear activities within the scope of the 1987 Nuclear Energy Act

    International Nuclear Information System (INIS)

    The Clean Air Act amendments alter the complex laws affecting atmospheric pollution and at the same time have broad implications for energy. Specifically, the Clean Air Act amendments for the first time deal with the environmental problem of acid deposition in a way that minimizes energy and economic impacts. By relying upon a market-based system of emission trading, a least cost solution will be used to reduce sulfur dioxide (SO2) emissions by almost 40 percent. The emission trading system is the centerpiece of the Clean Air Act (CAA) amendments effort to resolve energy and environmental interactions in a manner that will maximize environmental solutions while minimizing energy impacts. This paper will explore how the present CAA amendments deal with the emission trading system and the likely impact of the emission trading system and the CAA amendments upon the electric power industry

    2002-10-01

    A mathematical model of a hydraulic balancer in steady state condition was derived from a whirling model of a vertical axis washing machine, with the aim of implementing a dynamic analysis of an automatic washing machine during spin drying mode. The centrifugal force acting on the hydraulic balancer depends on the centroidal distance of the fluid in the hydraulic balancer, and the centroidal distance is a function of an eccentricity of the geometric center of the hydraulic balancer from the axis of rotation. A mathematical model of the hydraulic balancer in steady state is validated by the experimental result of the centrifugal force. Experiments were performed on a washing machine during spin drying mode, and results were compared with the simulation result. The parameters affecting the vibration of the washing machine were investigated by the parameter study.

  19. A Simple and Reasonable Calculation Equation of Balanced Fertilization

    2015-05-01

    Full Text Available Reasonable fertilization is a primary concern for agronomy scientists and farmers. However, there is still no satisfying calculation formula to guide farmer’s fertilizing. Five kinds of indices were tested in more than 500 field plots successively, and more than 50 pieces of long-term and short-term fertilizer field test data acquired by others were analyzed. Quick-acting fertilizers should be applied for balanced fertilization if the soil-available nutrient content is within the normal range. Through rigorous derivation and validation by a multi-year continuous 15N tracer field test, it is obtained that, total soil exogenous N = total output N − total recovery N + soil profit or lost N; utilization efficiency of fertilizer N = (output N − exogenous N ÷ balanced application amount of N fertilizer. Optimal balanced utilization efficiency of fertilizer N, P, K = total recovery efficiency, and soil nutrient net amount = total amount after test − total amount before test. Equation application parameters were collected from more than 50 tests, which is more applicable than collecting from a single test. When soil-available nutrient content is excessively low or excessively high, adjusting this should be based on balanced fertilization to properly increase or reduce the fertilization rate.

It distributes workload equally across all the nodes by using back propagation learning algorithm to train feed forward Artificial Neural Network (ANN. The proposed technique is simple and it can work efficiently when effective training sets are used. ANN predicts the demand and thus allocates resources according to that demand. Thus, it always maintains the active servers according to current demand, which results in low energy consumption than the conservative approach of over-provisioning. Furthermore, high utilization of server results in more power consumption, server running at higher utilization can process more workload with similar power usage. Finally the existing load balancing techniques in cloud computing are discussed and compared with the proposed technique based on various parameters like performance, scalability, associated overhead... etc. In addition energy consumption and carbon emission perspective are also considered to satisfy green computing.

    Full Text Available This article surveys studies on universally balanced properties of cooperative games defined in a succinct form. In particular, we focus on combinatorial optimization games in which the values to coalitions are defined through linear optimization programs, possibly combinatorial, that is subject to integer constraints. In economic settings, the integer requirement reflects some forms of indivisibility. We are interested in the classes of games that guarantee a non-empty core no matter what are the admissible values assigned to the parameters defining these programs. We call such classes universally balanced. We present characterization and complexity results on the universally balancedness property for some classes of interesting combinatorial optimization games. In particular, we focus on the algorithmic properties for identifying universally balancedness for the games under discussion.

    Rabin, Douglas

    1991-01-01

    The energy balance in magnetic flux tubes is examined semianalytically for the case in which thermal conduction balances radiation or in which enthalpy transport occurs. Different values are considered for areal constriction, shape, length, and maximum temperature. The overall energy budget of the solar corona is not significantly affected by magnetic constriction. A bowl-shaped funnel with a constriction factor of 4 describes the empirical differential-emission measure for log-T values between approximately 5.3 and 6.0. Loop-scaling relationships are derived for the full range of models to illustrate the dependence of the constant of proportionality on the properties of the magnetic constriction. Constriction can reduce the total energy requirement of the funnel by a factor of 5 and not affect the differential emission in flow-dominated models.

    Actuator/sensor locations and balanced representations of linear systems are considered for a given set of controllability and observability grammians. The case of equally controlled and observed states is given special attention. The assignability of grammians is examined, and the conditions for their existence are presented, along with several algorithms for their determination. Although an arbitrary positive semidefinite matrix is not always assignable, the identity grammian is shown to be always assignable. The results are extended to the case of flexible structures.

    A plane wall jet experiment has been done to study its momentum balance. Two component laser Doppler anemometry was used to simultaneously measure the axial and wall-normal velocity components in 6 axial positions (x/H= 25, 50, 75, 100, 125 and 150) spanning from the wall all the way well into the ambient stagnant area. In this way not only the mean velocity components and Reynolds normal and shear stresses but also all their spatial derivatives were determined. In addition the wall shear stress was measured in all six axial positions using oil film interferometry. From these data all terms in the x-momentum equation, except the pressure term, could be evaluated. Later also the pressure was measured in the same profiles, and thereby also the pressure term was included in the balance. Contrary to common belief it was found that the pressure was not constant in the wall jet. The complete momentum balance is discussed and used to evaluate the roles played by the different contributing terms in different regions of the flow field in an effort to improve on our understanding of the mechanics of wall jets.

  15. Constrained Allocation Flux Balance Analysis

    New experimental results on bacterial growth inspire a novel top-down approach to study cell metabolism, combining mass balance and proteomic constraints to extend and complement Flux Balance Analysis. We introduce here Constrained Allocation Flux Balance Analysis, CAFBA, in which the biosynthetic costs associated to growth are accounted for in an effective way through a single additional genome-wide constraint. Its roots lie in the experimentally observed pattern of proteome allocation for metabolic functions, allowing to bridge regulation and metabolism in a transparent way under the principle of growth-rate maximization. We provide a simple method to solve CAFBA efficiently and propose an “ensemble averaging” procedure to account for unknown protein costs. Applying this approach to modeling E. coli metabolism, we find that, as the growth rate increases, CAFBA solutions cross over from respiratory, growth-yield maximizing states (preferred at slow growth) to fermentative states with carbon overflow (preferred at fast growth). In addition, CAFBA allows for quantitatively accurate predictions on the rate of acetate excretion and growth yield based on only 3 parameters determined by empirical growth laws. PMID:27355325

    [Purpose] This study investigated efficacy of virtual reality (VR)-based balance training on enhancing balance and postural reactions of adults as a low-cost new modality compared to the established Biodex Balance System (BBS). [Subjects] Thirty normal adults of both genders were divided randomly into two equal-sized experimental groups of 15: BBS balance training and VR balance training. [Methods] The training programmes were conducted in 12 sessions, three 15-min sessions per week. The Nintendo® Wii Fit Plus (NWFP) and its balance board were used to train of the VR group. Each participant answered a questionnaire concerning usability, enjoyment, balance improvement, and fatigue at the end of the training programs. [Results] The study found a significant increase the measure of mean overall balance (OLB) in both groups. No significant difference was found between the groups, but a significant decrease in the mean balance-test time was found for both groups, with no significant difference between the two training methods. The VR programme was rated highly enjoyable by 81.8% of the group. [Conclusion] The Wii Fit Plus system with the balance board as a new VR balance-training technique, can be considered an effective and enjoyable tool for the training of adults’ body balance.

    1992-01-01

    Pakistan is a country whose economic growth is surprising in light of its social indicators. The aim of this article is to examine why conditions are such and to develop a framework for understanding the issues as an aid to redesigning policies. 5 sections are devoted to a summary of the main findings, the diagnosis of development and the impact on social sectors, a proposal for balanced development, and implications for policy changes. A sound macro economic context is needed with reforms economically in price and incentive systems, institutionally, and in the law and order sector. Public administration needs to be improved and individual opportunities need to be expanded. Internal security needs to be secured, so that law and order are restored. Economic growth has been high between 1960 and 1988, due to exploitation of natural resources and cheap unskilled labor, expansion of irrigated land, and growth of the unregulated informal sector. The major constraints on economic growth will come from a lack of fiscal discipline. 40% of government revenues are consumed by the military and 20% for servicing debt. Other constraints are the population growth rate in excess of 3%/year, an urban bias in allocation of resources, neglected primary education, and gender bias in education. There has been little incentive for provincial governments to balance budgets, and civil service has become disorganized. Balanced development entails recognizing human capital, natural resources, and infrastructure; accepting the status quo; and creating and maintaining an institutional framework to correct market failures and promote individual opportunities. The environmental polluter must pay. Income must be increased through higher wages, increasing the demand for labor, and transfers to households in the form of food rations, schooling, and medical care. Investment in women will increase household earnings, and improve living conditions and the health of themselves and their children

  14. Energy balances for power plants

    International Nuclear Information System (INIS)

    An important aspect of a power plant is its energy balance, i.e. the electrical energy produced by the plant over its overall operation period, compared to the amount of non-renewable energy used to create and build the plant. Tense discussions took place in the past between criticizers and promotors of a given technology, some technologies even being accused of having a negative energy balance. Mostly based on built examples the present study aims at giving objective data for the represented technologies, as follows: a 64 MW hydro power plant in the Alps, with seasonal water storage in a lake; a 60 MW run-of-river high-head hydro power plant in the Alps; two run-of-river low-head hydro power plants in the Swiss Midlands (14 MW and 25 MW respectively); a small 30 kW wind power generator located near the Simplon Pass at 2000 m over sea level, in the Alps; a 3 kW photovoltaic generator in the roof of a single-family house; a 500 kW photovoltaic power plant in the Jura, at 1000 m over sea level; a 0.9 MWel/8.8 MWtherm fossil-fuel co-generation plant near Zuerich; a 200 MW natural-gas-fired gas/vapour turbine power plant; a 300 MW heavy-fuel-fired power plant; a 500 MW coal-fired power plant; and the Leibstadt 990 MW nuclear power plant. The best energy balances are obtained for the hydro power plants, the worst for the Leibstadt nuclear power plant. In between the photovoltaic plants and the fossil-fuel-fired plants are found. The figures differ by more than two orders of magnitude

  15. Annual carbon balance of a peatland 10 yr following restoration

    Full Text Available Undisturbed peatlands represent long-term net sinks of carbon; however, peat extraction converts these systems into large and persistent sources of greenhouse gases. Although rewetting and restoration following peat extraction have taken place over the last several decades, very few studies have investigated the longer term impact of this restoration on peatland carbon balance. We determined the annual carbon balance of a former horticulturally-extracted peatland restored 10 yr prior to the study and compared these values to the carbon balance measured at neighboring unrestored and natural sites. Carbon dioxide (CO2 and methane (CH4 fluxes were measured using the chamber technique biweekly during the growing season from May to October 2010 and three times over the winter period. Dissolved organic carbon (DOC export was measured from remnant ditches in the unrestored and restored sites. During the growing season the restored site had greater uptake of CO2 than the natural site when photon flux density was greater than 1000 μmol m−2 s−1, while the unrestored site remained a source of CO2. Ecosystem respiration was similar between natural and restored sites, which were both significantly lower than the unrestored site. Methane flux remained low at the restored site except from open water pools, created as part of restoration, and remnant ditches. Export of DOC during the growing season was 5.0 and 28.8 g m−2 from the restored and unrestored sites, respectively. Due to dry conditions during the study year all sites acted as net carbon sources with annual balance of the natural, restored and unrestored sites of 250.7, 148.0 and 546.6 g C m−2, respectively. Although hydrological conditions and vegetation community at the restored site remained intermediate between natural and unrestored conditions, peatland restoration resulted in a large reduction in annual carbon loss from the system resulting in a carbon balance more similar to a natural

    @@ Changes in the content of European balance constitute the biggest difference between the economic integration model and its predecessors. Armament, territory and resources were considered as key factors for enhanced strength and sustained power parity with other nations. Transition to economic integration has however entailed decoupling of the two. Enhanced national strength now aims instead at power parity and shared power based on common European interests and inter-dependency rather than at weakening other nations. As a result, state relations there are moving toward fusion and convergence.

  5. Field balancing in the real world

    Energy Technology Data Exchange (ETDEWEB)

    Bracher, B.

    1997-09-05

    Field balancing can achieve significant results when other problems are present in the frequency spectrum and multiple vibrations are evident in the waveform. Many references suggest eliminating other problems before attempting to balance. That`s great - if you can do it. There are valid reasons for this approach, and it would be much easier to balance machinery when other problems have been corrected. It is the theoretical ideal in field balancing. However, in the real world of machinery maintained for years by reacting to immediate problems, the classic vibration signature for unbalance is rarely seen. Maintenance personnel make most of their decisions with limited information. The decision to balance or not to balance is usually made the same way. This paper will demonstrate significant results of field balancing in the presence of multiple problems. By examining the data available and analyzing the probabilities, a reasonable chance for success can be assured.

  6. Ecological, biological balances and conservation

    International Nuclear Information System (INIS)

    The scientific work within the activity ''ecological/biological balances and conservation'' is summarised in this report. The aims of the activity during its existence between 1992 and 1994 have been to: (i) arrange a workshop and publish the presentations on the environmental aspects of energy forest cultivations, (ii) perform joint scientific work together with the activity group on ''biological disposal of wastewaters and sludges'', that is closely related to environmental problems, and (iii) produce ecological guidelines concerning energy forestry, suitable for advisers and farmers dealing with bioenergy problems. The most important results from the workshop were the environmental benefits from energy forestry when compared with intensive agriculture and forestry. Energy forestry has positive influence on the carbon balances, nutrient recycling, and soil sustainability. The effects are also positive on the natural flora and fauna, which in most cases are enriched when compared with agricultural crops. From the joint efforts of the two activities the main result was a study tour, conference and workshop, concentrating on biological purification systems. The most promising system seems to be the vegetation filters of short rotation coppice. The report on ecological guidelines contains a number of ideas and recommendations for establishment, management, and harvesting of energy forests in an environmentally acceptable way. It also gives advice on how to locate the stands to minimise the risk of nutrient leakage from arable land. (Author)

  7. Differential force balances during levitation

    Science.gov (United States)

    Todd, Paul

    The simplest arithmetic of inertial, buoyant, magnetic and electrokinetic levitation is explored in the context of a model living system with “acceleration-sensitive structures” in which motion, if allowed, produces a biological effect. The simple model is a finite-sized object enclosed within another finite-sized object suspended in an outer fluid (liquid or vapor) medium. The inner object has density and electrical and magnetic properties quantitatively different from those of the outer object and the medium. In inertial levitation (“weightlessness”) inertial accelerations are balanced, and the forces due to them are canceled in accordance with Newton’s third law. In the presence of inertial acceleration (gravity, centrifugal) motionlessness depends on a balance between the levitating force and the inertial force. If the inner and outer objects differ in density one or the other will be subjected to an unbalanced force when one object is levitated by any other force (buoyant, magnetic, electrokinetic). The requirements for motionlessness of the internal object in the presence of a levitating force are equality of density in the case of buoyant levitation, equality of magnetic susceptibility in the case of magnetic levitation, and equality of zeta potential and dielectric constant in the case of electrokinetic levitation. Examples of internal “acceleration-sensitive structures” are cellular organelles and the organs of advanced plants and animals. For these structures fundamental physical data are important in the interpretation of the effects of forces used for levitation.

  8. Mass balance assessment using GPS

    Science.gov (United States)

    Hulbe, Christina L.

    1993-01-01

    Mass balance is an integral part of any comprehensive glaciological investigation. Unfortunately, it is hard to determine at remote locations where there is no fixed reference. The Global Positioning System (GPS) offers a solution. Simultaneous GPS observations at a known location and the remote field site, processed differentially, will accurately position the camp site. From there, a monument planted in the firn atop the ice can also be accurately positioned. Change in the monument's vertical position is a direct indicator of ice thickness change. Because the monument is not connected to the ice, its motion is due to both mass balance change and to the settling of firn as it densifies into ice. Observations of relative position change between the monument and anchors at various depths within the firn are used to remove the settling effect. An experiment to test this method has begun at Byrd Station on the West Antarctic Ice Sheet and the first epoch of observations was made. Analysis indicates that positioning errors will be very small. It appears likely that the largest errors involved with this technique will arise from ancillary data needed to determine firn settling.

    Full Text Available Abstract Background In their current laboratory-based form, existing vibrotactile sensory augmentation technologies that provide cues of body motion are impractical for home-based rehabilitation use due to their size, weight, complexity, calibration procedures, cost, and fragility. Methods We have designed and developed a cell phone based vibrotactile feedback system for potential use in balance rehabilitation training in clinical and home environments. It comprises an iPhone with an embedded tri-axial linear accelerometer, custom software to estimate body tilt, a "tactor bud" accessory that plugs into the headphone jack to provide vibrotactile cues of body tilt, and a battery. Five young healthy subjects (24 ± 2.8 yrs, 3 females and 2 males and four subjects with vestibular deficits (42.25 ± 13.5 yrs, 2 females and 2 males participated in a proof-of-concept study to evaluate the effectiveness of the system. Healthy subjects used the system with eyes closed during Romberg, semi-tandem Romberg, and tandem Romberg stances. Subjects with vestibular deficits used the system with both eyes-open and eyes-closed conditions during semi-tandem Romberg stance. Vibrotactile feedback was provided when the subject exceeded either an anterior-posterior (A/P or a medial-lateral (M/L body tilt threshold. Subjects were instructed to move away from the vibration. Results The system was capable of providing real-time vibrotactile cues that informed corrective postural responses. When feedback was available, both healthy subjects and those with vestibular deficits significantly reduced their A/P or M/L RMS sway (depending on the direction of feedback, had significantly smaller elliptical area fits to their sway trajectory, spent a significantly greater mean percentage time within the no feedback zone, and showed a significantly greater A/P or M/L mean power frequency. Conclusion The results suggest that the real-time feedback provided by this system can be used

  12. Single Switched Capacitor Battery Balancing System Enhancements

    Full Text Available Battery management systems (BMS are a key element in electric vehicle energy storage systems. The BMS performs several functions concerning to the battery system, its key task being balancing the battery cells. Battery cell unbalancing hampers electric vehicles’ performance, with differing individual cell voltages decreasing the battery pack capacity and cell lifetime, leading to the eventual failure of the total battery system. Quite a lot of cell balancing topologies have been proposed, such as shunt resistor, shuttling capacitor, inductor/transformer based and DC energy converters. The shuttling capacitor balancing systems in particular have not been subject to much research efforts however, due to their perceived low balancing speed and high cost. This paper tries to fill this gap by briefly discussing the shuttling capacitor cell balancing topologies, focusing on the single switched capacitor (SSC cell balancing and proposing a novel procedure to improve the SSC balancing system performance. This leads to a new control strategy for the SSC system that can decrease the balancing system size, cost, balancing time and that can improve the SSC balancing system efficiency.

    This project measured pre-season balance ability and determined its relationship to knee and ankle ligament injuries during the season for professional Australian footballers. The balance test involved the players stepping onto a foam balance mat on top of a force plate and maintaining single limb balance. Throughout the playing season, injuries were monitored. The results from two hundred and ten players participating in this project were analysed. During the 2003 season, 8 % (17 out of 210) sustained a knee ligament injury and 10 % (21 out of 210) sustained an ankle ligament injury. Multivariate analysis revealed that pre-season balance ability was a significant independent predictor of ankle ligament injury. Players with low balance ability had at least twice as many ankle ligaments injuries as those with average or good balance ability. Balance ability was not a significant predictor of knee ligament injuries. The height of the players was the only significant independent predictor of knee ligament injuries. Low pre-season balance ability was associated with an increased risk of ankle ligament injury. A modifiable injury risk factor has been identified. Research is now required to determine the optimal training regime to enhance balance ability and whether this translates to a reduction in the incidence of ankle injuries. PMID:17373597

  16. Policy gridlock in waste management: Balancing federal and state concerns

    International Nuclear Information System (INIS)

    Current federal hazardous and low-level radioactive waste management policies fail to balance national concerns for policy consistency with state concerns for equity, discretion, and adequate resources. Failure to balance these competing values has resulted in open-quotes policy gridlockclose quotes - exemplified by conflicts over the Resource Conservation and Recovery Act and the Low-Level Radioactive Waste Policy Acts. Both conflicts have resulted in recent U.S. Supreme Court litigation. After reviewing federal-state conflict in hazardous and low-level radioactive waste management, we propose that the solution to gridlock lies in modifying conjoint federalism. Conjoint federalism allows for joint responsibility for waste policy between federal and state governments, with state programs meeting minimum standards set by federal programs. However, conjoint federalism does not currently allow for sufficient state discretion, which is paramount for successful waste management programs. Specifically, Congress should expand conjoint federalism, to allow states to charge differential fees on imported hazardous waste as is done for low-level radioactive waste. This expansion would encourage waste minimization and better interstate planning

    North, G. R.; Cahalan, R. F.; Coakley, J. A., Jr.

    1980-01-01

    An introductory survey of the global energy balance climate models is presented with an emphasis on analytical results. A sequence of increasingly complicated models involving ice cap and radiative feedback processes are solved and the solutions and parameter sensitivities are studied. The model parameterizations are examined critically in light of many current uncertainties. A simple seasonal model is used to study the effects of changes in orbital elements on the temperature field. A linear stability theorem and a complete nonlinear stability analysis for the models are developed. Analytical solutions are also obtained for the linearized models driven by stochastic forcing elements. In this context the relation between natural fluctuation statistics and climate sensitivity is stressed.

  18. A Generalized Detailed Balance Relation

    Given a system M in a thermal bath we obtain a generalized detailed balance relation for the ratio r=π _τ (K→ J)/π _τ (J→ K) of the transition probabilities M:J→ K and M:K→ J in time τ . We assume an active bath, containing solute molecules in metastable states. These molecules may react with M and the transition J→ K occurs through different channels α involving different reactions with the bath. We find that r=sum p^α r^α , where p^α is the probability that channel α occurs, and r^α depends on the amount of heat (more precisely enthalpy) released to the bath in channel α.

  19. Carbon and water vapor balance in a subtropical pine plantation

    2016-05-01

    Full Text Available Afforestation has been proposed as an effective tool for protecting primary and/or secondary forests and for mitigating atmospheric CO2. However, the dynamics of primary productivity differs between plantations and natural forests. The objective of this work was to evaluate the potential for carbon storage of a commercial pine plantation by determining its carbon balance. Measurements started when trees were aged 6 and ended when they were older than 8 years. We measured CO2 and water vapor concentrations using the Eddy covariance method. Gross primary productivity in 2010 and 2011 was 4290 ± 473 g C m-2 and 4015 ± 485 g C m-2, respectively. Ecosystem respiration ranged between 7 and 20 g C m-2 d-1, reaching peaks in all Februaries. Of the 30 months monitored, the plantation acted as carbon source for 21 months and as carbon sink for 6 months, while values close to neutrality were obtained during 3 months. The positive balance representing CO2 loss by the system was most likely due to the cut branches left on the ground following pruning activities. The plantation was subjected to pruning in January and September 2008 and to sanitary pruning in October 2010. In all cases, cut branches were not removed but remained on the ground. Residue management seems to have a very important impact on carbon balance.

  20. Sodium balance-an integrated physiological model and novel approach

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available Various physiological mechanisms regulate sodium and water balance in the human body. These processes achieve acute and chronic sodium regulation and the simultaneous or se-quential changes can be explained using a single physiological model. Steady intracellular water and osmolality is necessary for cell membrane integrity and cellular processes. Body fluids protect circulatory blood volume by altering Na + and water balance. This is the most vital homeostatic function of the body. Changes in ECF volume are sensed by various cardinal sensors. Physio-logically, the main aim of Na + and water balance is to permit variable salt and water intake without large fluctuations in blood pressure or volume status. Homeostatic processes act in an integrated fashion to protect against any perturbations. Characteristically, these mechanisms are sequential as well as parallel. These may be synergistic or antagonistic to each other. Rapidity, sensitivity and potency of these powerful feedback systems differ. Various physiological and pathological insults determine the magnitude of response of these systems.

  1. Relevance of balance measurement tools and balance training for fall prevention in older adults

    Directory of Open Access Journals (Sweden)

    Majumi M. Noohu, MPTh

    2014-06-01

    Full Text Available Approximately one in three older people fall each year owing to gait/balance disorder/weakness, the second leading cause of falls in older adults. This review evaluates the capability of different balance measurement tools to predict falls in the elderly, which are used routinely for assessing balance impairment. Balance measurement tools reviewed are the Timed Up and Go test, Berg Balance Scale, Tinetti Performance Oriented Mobility Assessment, Functional Reach Test, Clinical Test of Sensory Integration for Balance, and the postural sway measurements or center of pressure. The effect of balance training on the postural control mechanism and its efficacy in fall prevention in older adults were also reviewed. The current evidence is not conclusive enough to favor existing balance measurement tools and balance training implemented for fall prevention in older adults.

  2. Local detailed balance: a microscopic derivation

    International Nuclear Information System (INIS)

    Thermal contact is the archetype of non-equilibrium processes driven by constant non-equilibrium constraints when the latter are enforced by reservoirs exchanging conserved microscopic quantities. At a mesoscopic scale only the energies of the macroscopic bodies are accessible together with the configurations of the contact system. We consider a class of models where the contact system, as well as macroscopic bodies, have a finite number of possible configurations. The global system, with only discrete degrees of freedom, has no microscopic Hamiltonian dynamics, but it is shown that, if the microscopic dynamics is assumed to be deterministic and ergodic and to conserve energy according to some specific pattern, and if the mesoscopic evolution of the global system is approximated by a Markov process as closely as possible, then the mesoscopic transition rates obey three constraints. In the limit where macroscopic bodies can be considered as reservoirs at thermodynamic equilibrium (but with different intensive parameters), the mesoscopic transition rates turn into transition rates for the contact system and the third constraint becomes local detailed balance; the latter is generically expressed in terms of the microscopic exchange entropy variation, namely the opposite of the variation of the thermodynamic entropy of the reservoir involved in a given microscopic jump of the contact system configuration. For a finite-time evolution after contact has been switched on, we derive a fluctuation relation for the joint probability of the heat amounts received from the various reservoirs. The generalization to systems exchanging energy, volume and matter with several reservoirs, with a possible conservative external force acting on the contact system, is given explicitly. (paper)

  5. Milestones in gait, balance, and falling.

    Science.gov (United States)

    Nutt, John G; Horak, Fay B; Bloem, Bastiaan R

    2011-05-01

    Gait, balance, and falls have become increasingly common topics of published articles in the Movement Disorders journal since its launch in 1986. This growth represents an increasing awareness of the importance of mobility to patients' quality of life. New methods have become available that allow for accurate measurement of many aspects for gait and balance. This has led to new concepts of understanding gait and balance disorders. Neuroimaging has begun to reveal the neural circuitry underlying gait and balance. The physiology and pathophysiology of balance and gait are beginning to tease out the many processes involved in mobility and how they may be disrupted by disease processes. With these advances, the old therapeutic nihilism that characterized the clinician's approach to falls and gait disorders is disappearing, as innovative physiotherapy, exercise, drugs, and deep brain stimulation are being employed for gait and balance disorders.

  6. Balance Systems and the Variational Bicomplex

    Preston, Serge

    2011-07-01

    In this work we show that the systems of balance equations (balance systems) of continuum thermodynamics occupy a natural place in the variational bicomplex formalism. We apply the vertical homotopy decomposition to get a local splitting (in a convenient domain) of a general balance system as the sum of a Lagrangian part and a complemental ''pure non-Lagrangian'' balance system. In the case when derivatives of the dynamical fields do not enter the constitutive relations of the balance system, the ''pure non-Lagrangian'' systems coincide with the systems introduced by S. Godunov [Soviet Math. Dokl. 2 (1961), 947-948] and, later, asserted as the canonical hyperbolic form of balance systems in [Müller I., Ruggeri T., Rational extended thermodynamics, 2nd ed., Springer Tracts in Natural Philosophy, Vol. 37, Springer-Verlag, New York, 1998].

    Hufnagel, K.; Ewald, B.; Graewe, E.

    The five cryogenic wind-tunnel balances which were built and calibrated as part of the cryogenic balance program initiated in 1979 by the German Ministry of Research and Technology are described. Particular attention is given to factors affecting the calibration of cryogenic balances, such as the changes in the temperature and temperature gradients in the balance body caused by changes in the tunnel temperature. It is shown that it is possible to have a cryogenic wind-tunnel balance with the same accuracy and repeatability as a conventional balance. The effect of temperature gradients can be minimized by a new design of the axial-force element and an advanced calibration, and the zero shift can be reduced by matching procedures and calibration.

  9. Proteolytic-antiproteolytic balance and its regulation in carcinogenesis

    Cancer development is essentially a tissue remodeling process in which normal tissue is substituted with cancer tissue. A crucial role in this process is attributed toproteolytic degradation of the extracellular matrix (ECM).Degradation of ECM is initiated by proteases, secreted by different cell types, participating in tumor cell invasion and increased expression or activity of every known class of proteases (metallo-, serine-, aspartyl-, and cysteine)has been linked to malignancy and invasion of tumor cells.Proteolytic enzymes can act directly by degrading ECM or indirectly by activating other proteases, which then degrade the ECM. They act in a determined order, resulting from the order of their activation. When proteases exert their action on other proteases, the end result is a cascade leading to proteolysis. Presumable order of events in this complicated cascade is that aspartyl protease (cathepsin D) activates cysteine proteases (e.g. cathepsin B) that can activate pro-uPA. Then active uPA can convert plasminogen into plasmin. Cathepsin B as well as plasmin are capable of degrading several components of tumor stroma and may activate zymogens of matrix metalloproteinases, the main family of ECM degrading proteases. The activities of these proteases are regulated by a complex array of activators,inhibitors and cellular receptors. Tn physiological conditions the balance exists between proteases and their inhibitors.Proteolytic-antiproteolytic balance may be of major significance in the cancer development. One of the reasons for such a situation is enhanced generation of free radicals observed in many pathological states. Free radicals react with main cellular components like proteins and lipids and in this way modify proteolytic-antiproteolytic balance and enable penetration damaging cellular membrane. All these lead to enhancement of proteolysis and destruction of ECM proteins and in consequence to invasion and metastasis.

    Particular attention is given to the spatial variability that affects the representation of water balance at the catchment scale in the context of macroscale water-balance modeling. Remotely sensed data are employed for parameterization, and the resulting model is developed so that subgrid spatial variability is preserved and therefore influences the grid-scale fluxes of the model. The model permits the quantitative evaluation of the surface-atmospheric interactions related to the large-scale hydrologic water balance.

    The balance of military forces is meant to prevent war. But it is a very precarious balance, which becomes all the more dubious when the deterrent is no longer psychologically effective: when the country attacked is deterred from striking back with nuclear weapons. A unilateral disarmament above the overkill level would be possible without endangering the balance. It would improve the climate for mutual disarmament. (orig.)

    Science.gov (United States)

    Wicks, Angela M; St Clair, Lynda

    2007-01-01

    Facing a complex environment driven by two decades of dramatic change, healthcare organizations are adopting new strategic frameworks such as the Balanced Scorecard (BSC) to evaluate performance (Kaplan and Norton 1992). The BSC was not originally developed as a performance management tool, however. Rather, it was designed as a tool to communicate strategy and, as such, provides little guidance when actual outcomes fall short of desired outcomes. In addition, although the BSC is an improvement over exclusively financial measures, it has three conceptual limitations that are especially problematic for evaluating healthcare organizations: (1) it underemphasizes the employee perspective, (2) it is founded on a control-based management philosophy, and (3) it emphasizes making trade-offs. To address these limitations, we propose using the Competing Values Framework (CVF), a theoretically grounded, comprehensive approach to understanding and improving organizational and managerial performance by focusing on four action imperatives: competing, controlling, collaborating, and creating. The CVF pays particular attention to the employee perspective, is consistent with a commitment-based management philosophy, and emphasizes transcending apparent paradoxes to identify win-win solutions. Rather than focusing on customer satisfaction or employee satisfaction, the CVF looks for ways to satisfy customers and employees while still addressing financial constraints and growth opportunities. The CVF also can be used to assess both the culture of the organization and the competencies of individual managers, thereby providing a clear link between strategy and implementation. PMID:17933187

  3. Balancing energy strategies in electricity portfolio management

    International Nuclear Information System (INIS)

    Traditional management of electricity portfolios is focused on the day-ahead market and futures of longer maturity. Within limits, market participants can however also resort to the balancing energy market to close their positions. In this paper, we determine strategic positions in the balancing energy market and identify corresponding economic incentives in an analysis of the German balancing energy demand. We find that those strategies allow an economically optimal starting point for real-time balancing and create a marketplace for flexible capacity that is more open than alternative marketplaces. The strategies we proffer in this paper we believe will contribute to an effective functioning of the electricity market. (author)

    Carbon balance is an important instrument to identify the emission sources of greenhouse effect gases. Since energy use and transformation are fundamental for increasing these gases in the atmosphere, the carbon balance survey can be used to identify sectors and fuels to which priority should be given regarding emissions mitigation. In the case of transformation centers (installations where primary or secondary sources are converted into sub-products or other energy form) the balance indicated some problems regarding the Brazilian inventory calculation. Problems concerning the National Energy Balance data used here were also identified. (author)

    Full Text Available Guava response to liming and fertilization can be monitored by tissue testing. Tissue nutrient signature is often diagnosed against nutrient concentration standards. However, this approach has been criticized for not considering nutrient interactions and to generate numerical biases as a result of data redundancy, scale dependency and non-normal distribution. Techniques of compositional data analysis can control those biases by balancing groups of nutrients, such as those involved in liming and fertilization. The sequentially arranged and orthonormal isometric log ratios (ilr or balances avoid numerical bias inherent to compositional data. The objectives were to relate tissue nutrient balances with the production of "Paluma" guava orchards differentially limed and fertilized, and to adjust the current patterns of nutrient balance with the range of more productive guava trees. It was conducted one experiment of 7-yr of liming and three experiments of 3-yr with N, P and K trials in 'Paluma' orchards on an Oxisol. Plant N, P, K, Ca and Mg were monitored yearly. It was selected the [N, P, K | Ca, Mg], [N, P | K], [N | P] and [Ca | Mg] balances to set apart the effects of liming (Ca-Mg and fertilizers (N-K on macronutrient balances. Liming largely influenced nutrient balances of guava in the Oxisol while fertilization was less influential. The large range of guava yields and nutrient balances allowed defining balance ranges and comparing them with the critical ranges of nutrient concentration values currently used in Brazil and combined into ilr coordinates.

    It is generally assumed that the mass-balance gradient on glaciers is more or less conserved under climatic change. In studies of the dynamic response of glaciers to climatic change, one of the following assumptions is normally made: (i) the mass-balance perturbation is independent of altitude or (ii) the mass-balance profile does not change - it simply shifts up and down. Observational evidence for such an approach is not convincing; on some glaciers the inter-annual changes in mass balance ...

  12. Network stability is a balancing act of personality, power, and conflict dynamics in rhesus macaque societies.

    Directory of Open Access Journals (Sweden)

    Brenda McCowan

    Full Text Available Stability in biological systems requires evolved mechanisms that promote robustness. Cohesive primate social groups represent one example of a stable biological system, which persist in spite of frequent conflict. Multiple sources of stability likely exist for any biological system and such robustness, or lack thereof, should be reflected and thus detectable in the group's network structure, and likely at multiple levels. Here we show how network structure and group stability are linked to the fundamental characteristics of the individual agents in groups and to the environmental and social contexts in which these individuals interact. Both internal factors (e.g., personality, sex and external factors (e.g., rank dynamics, sex ratio were considered from the level of the individual to that of the group to examine the effects of network structure on group stability in a nonhuman primate species. The results yielded three main findings. First, successful third-party intervention behavior is a mechanism of group stability in rhesus macaques in that successful interventions resulted in less wounding in social groups. Second, personality is the primary factor that determines which individuals perform the role of key intervener, via its effect on social power and dominance discrepancy. Finally, individuals with high social power are not only key interveners but also key players in grooming networks and receive reconciliations from a higher diversity of individuals. The results from this study provide sound evidence that individual and group characteristics such as personality and sex ratio influence network structures such as patterns of reconciliation, grooming and conflict intervention that are indicators of network robustness and consequent health and well-being in rhesus macaque societies. Utilizing this network approach has provided greater insight into how behavioral and social processes influence social stability in nonhuman primate groups.

  13. The Down Syndrome Information Act: Balancing the Advances of Prenatal Testing Through Public Policy.

    2016-04-01

    Since the dawn of prenatal testing in the 1970s, concerns have been raised over its administration to respect a mother's autonomy as well as the expressive critique against those with the tested-for condition. Advances in prenatal testing have made it such that more mothers than ever are given a test result of Down syndrome, yet are not provided the rest of the information recommended by professional guidelines. In response, first federal legislation and then, increasingly, state legislation is requiring that this information be provided to expectant mothers. Though receiving broad bipartisan support in passage, some of the statutes have received criticism. These public policy measures will be surveyed and evaluated as to their relative merits and limitations. PMID:27028250

  14. Control of the reproductive axis: Balancing act between stimulatory and inhibitory inputs.

    Bédécarrats, Grégoy Y

    2015-04-01

    As for most vertebrates, reproduction in poultry is controlled by an integrated axis [the hypothalamo-pituitary-gonadal (HPG) axis]. External and internal cues are integrated at the level of the hypothalamus to initiate gonadal recruitment and control the subsequent reproductive cycle. Until recently, it was believed that the HPG was exclusively under stimulatory control from hypothalamic gonadotropin releasing hormone (GnRH). However in 2000, the discovery of gonadotropin inhibitory hormone (GnIH), an inhibitory peptide, changed this dogma. Since then, evidence accumulated to confirm that in fact the HPG is under a dual control system with a stimulatory and an inhibitory branch. In this paper, we review the organization of this dual control system, the mechanisms controlling the synthesis and release of GnRH and GnIH, and the possible integration and interactions between the two branches to regulate pituitary gonadotropes' function. Furthermore, as light perception and photoperiod are the primary cues utilized by the poultry industry in controlled environments, special consideration was given to potential practical applications.

    Full Text Available Thirty-two pre-service special education teachers carried out a 14-week informal practicum arranged for the purposes of this research to accompany the three classes they were taking in their program of study and to provide them with the needed setting and opportunities for hands-on experiences and reflection as they construct an understanding of the content offered to them in the program. Data were collected via structured observation, interviews, weekly reflection logs, and group discussions. Qualitative methods were employed to capture the developmental processes of the pre-service teachers. The study utilized the Critical Realistic perspective and the Ecological Systems Theory as theoretical framework. The teachers seemed to have developed their own vision to overcome theory–practice gap and were more open to collaborative efforts by the end of the study. Findings are discussed and implications for special education teacher preparation are deliberated.

    Full Text Available Using mice that lack retinaldehyde dehydrogenase 1 gene (Raldh1-/- mice, Kierfer et al demonstrated that retinoids (metabolites of Vitamin A play an important role in the regulation of cellular metabolisms and energetics. The Aldh1a1-/- mice were leaner and less prone to accumulate subcutaneous and visceral fat, and to acquire insulin resistance on high fat diet. Their lower fasting glucose levels concomitant with reduced hepatic expression of glucose 6-phosphatase and phosphoenol pyruvate carboxy kinase genes indicated that Aldh1a1-/- mice were defective in gluconeogenesis. These mice also had lower plasma levels of triglycerides, very low-density lipoprotein and low-density lipoprotein-triacylglycerol, while their skeletal muscles elicited higher expression of carnitine palmatoyl transferase, medium chain acyl-A dehydrogenase, peroxisome proliferation activated receptor (PPARα and PPARδ. Thus, the improved lipid and lipoprotein profiles of Raldh1a1-/- mice resulted from a combination of reduced lipogenesis and enhanced fatty acid oxidation by retinoids. The mechanistic details of how retinoids integrate fasting glucose, hepatic gluconeogenesis and adaptive thermogenesis independent of body mass deserve further study.

  1. Pairing and anti-pairing: a balancing act in the diploid genome

    Science.gov (United States)

    Joyce, Eric F.; Erceg, Jelena; Wu, C.-ting

    2016-01-01

    The presence of maternal and paternal homologs appears to be much more than just a doubling of genetic material. We know this because genomes have evolved elaborate mechanisms that permit homologous regions to sense and then respond to each other. One way in which homologs communicate is to come into contact and, in fact, Dipteran insects such as Drosophila excel at this task, aligning all pairs of maternal and paternal chromosomes, end-to-end, in essentially all somatic tissues throughout development. Here, we reexamine the widely held tenet that extensive somatic pairing of homologous sequences cannot occur in mammals and suggest, instead, that pairing may be a widespread and significant potential that has gone unnoticed in mammals because they expend considerable effort to prevent it. We then extend this discussion to interchromosomal interactions, in general, and speculate about the potential of nuclear organization and pairing to impact inheritance. PMID:27065367

  3. Cockpit Interruptions and Distractions: Effective Management Requires a Careful Balancing Act

    Science.gov (United States)

    Dismukes, R. K.; Young, Grant E.; Sumwalt, Robert L., III; Null, Cynthia H. (Technical Monitor)

    1998-01-01

    Managing several tasks concurrently is an everyday part of cockpit operations. For the most part, crews handle concurrent task demands efficiently, yet crew preoccupation with one task to the detriment of performing other tasks is one of the more common forms of error in the cockpit. Most pilots are familiar with the December 1972 L1011 crash that occurred when the crew became preoccupied with a landing gear light malfunction and failed to notice that someone had inadvertently bumped off the autopilot. More recently a DC-9 landed gear-up in Houston when the crew, preoccupied with an stabilized approach, failed to recognize that the gear was not down because they had not switched the hydraulic pumps to high. We have recently started a research project to study why crews are vulnerable to these sorts of errors. As part of that project we reviewed NTSB reports of accidents attributed to crew error; we concluded that nearly half of these accidents involved lapses of attention associated with interruptions, distractions, or preoccupation with one task to the exclusion of another task. We have also analyzed 107 ASRS reports involving competing tasks; we present here some of our conclusions from those ASRS reports. These 107 reports involved 21 different types of routine tasks crews neglected at a critical moment while attending to another task. Sixty-nine percent of the neglected tasks involved either failure to monitor the current status or position of the aircraft or failure to monitor the actions of the pilot flying or taxiing. Thirty-four different types of competing activities distracted or preoccupied the pilots. Ninety percent of these competing activities fell into one of four broad categories: communication (e.g., discussion among crew or radio communication), heads-down work (e.g., programming the FMS or reviewing approach plates), responding to abnormals, or searching for VMC traffic. We will discuss examples of each of these four categories and suggest things crews can do to reduce their vulnerability to these and similar situations.

  7. Energy Balance and Physical Activity

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    The prevalence of obesity is increasing in most parts of theworld and becoming one of the major global public health problems. Although the components of energy balance have not been adequately estimated over time, available evidence suggests that the increase in obesity is the result of reduced physical activity. Increases in physical activity have been shown to be strongly associated with improving physical fitness and body composition, with probably a positive effect on resting metabolic rate. The Surgeon General's Report on Physical Activity and Health advocates that 30 min of regular, moderate-intensity physical activity is associated with decreases in the risk of chronic diseases and may contribute to quality of life. However, the small changes that contribute 10 min for 3 times a day for aerobic training, or one set instead of three sets of repetitions on resistance training will provide individuals with health benefits. Indeed, nutrition and physical activity should be considered an integral part of fitness and good health, and should be encouraged in all age groups, particularly early in life. The question is no longer centered around the health benefit of increasing physical activity, but rather creating self awareness and behavior changes in individuals. Hence, effective intervention programs are needed that foster long term changes in physical activity. Among various interventions, the Nutrifit program was recently conducted in Thailand and found to improve health related fitness in children. The development of more effective interventions and approaches is a major challenge in this field today.

  8. Vulnerability of pension fund balances

    Ólafur Ísleifsson

    2012-12-01

    Full Text Available Although the Icelandic general labour market pension funds are built on the proviso that pension schemes are fully funded these funds are still grappling with the devastating financial effects of the 2008 economic collapse that rendered most of them in a significant actuarial deficit. The public sector pension funds are based on an employer guarantee that makes up for any lack of funding that historically has been quite significant. We identify the relatively high actuarial discount rate and increasing longevity as two factors that add to the vulnerability of the Icelandic pension system. We present a stochastic model in order to obtain reasonably sound estimates of the effect of revising such key parameters of the actuarial assessments of the pension funds and thus obtain a view of the viability of the Icelandic pension system when confronted with the potential necessity of such parameter shifts. We present results of stochastic simulations of this models made to assess effects of changes in these major financial and demographic assumptions in actuarial evaluations of pension fund balances. Our results suggest that the Icelandic pension funds may be significantly less well funded than is generally perceived.

    Aposematic signals are often characterized by high conspicuousness. Larger and brighter signals reinforce avoidance learning, distinguish defended from palatable prey and are more easily memorized by predators. Conspicuous signalling, however, has costs: encounter rates with naive, specialized or nutritionally stressed predators are likely to increase. It has been suggested that intermediate levels of aposematic conspicuousness can evolve to balance deterrence and detectability, especially for moderately defended species. The effectiveness of such signals, however, has not yet been experimentally tested under field conditions. We used dough caterpillar-like baits to test whether reduced levels of aposematic conspicuousness can have survival benefits when predated by wild birds in natural conditions. Our results suggest that, when controlling for the number and intensity of internal contrast boundaries (stripes), a reduced-conspicuousness aposematic pattern can have a survival advantage over more conspicuous signals, as well as cryptic colours. Furthermore, we find a survival benefit from the addition of internal contrast for both high and low levels of conspicuousness. This adds ecological validity to evolutionary models of aposematic saliency and the evolution of honest signalling. PMID:27484645

  10. Integral torque balance in tokamaks

    International Nuclear Information System (INIS)

    The study is aimed at clarifying the balance between the sinks and sources in the problem of intrinsic plasma rotation in tokamaks reviewed recently by deGrassie (2009 Plasma Phys. Control. Fusion 51 124047). The integral torque on the toroidal plasma is calculated analytically using the most general magnetohydrodynamic (MHD) plasma model taking account of plasma anisotropy and viscosity. The contributions due to several mechanisms are separated and compared. It is shown that some of them, though, possibly, important in establishing the rotation velocity profile in the plasma, may give small input into the integral torque, but an important contribution can come from the magnetic field breaking the axial symmetry of the configuration. In tokamaks, this can be the error field, the toroidal field ripple or the magnetic perturbation created by the correction coils in the dedicated experiments. The estimates for the error-field-induced electromagnetic torque show that the amplitude of this torque is comparable to the typical values of torques introduced into the plasma by neutral beam injection. The obtained relations allow us to quantify the effect that can be produced by the existing correction coils in tokamaks on the plasma rotation, which can be used in experiments to study the origin and physics of intrinsic rotation in tokamaks. Several problems are proposed for theoretical studies and experimental tests.

  13. Gait and balance disorders in older adults.

    Salzman, Brooke

    2010-07-01

    Gait and balance disorders are common in older adults and are a major cause of falls in this population. They are associated with increased morbidity and mortality, as well as reduced level of function. Common causes include arthritis and orthostatic hypotension; however, most gait and balance disorders involve multiple contributing factors. Most changes in gait are related to underlying medical conditions and should not be considered an inevitable consequence of aging. Physicians caring for older patients should ask at least annually about falls, and should ask about or examine for difficulties with gait and balance at least once. For older adults who report a fall, physicians should ask about difficulties with gait and balance, and should observe for any gait or balance dysfunctions. The Timed Up and Go test is a fast and reliable diagnostic tool. Persons who have difficulty or demonstrate unsteadiness performing the Timed Up and Go test require further assessment, usually with a physical therapist, to help elucidate gait impairments and related functional limitations. The most effective strategy for falls prevention involves a multifactorial evaluation followed by targeted interventions for identified contributing factors. Evidence on the effectiveness of interventions for gait and balance disorders is limited because of the lack of standardized outcome measures determining gait and balance abilities. However, effective options for patients with gait and balance disorders include exercise and physical therapy. PMID:20590073

    Full-state feedback parametric controllers are proposed for standing balance of humanoid robots in response to impulsive and constant pushes. Multiple robot models are used to approach multiple strategies in human standing balance. For each model,we design a parametric controller acting on each state variable and optimize controller parameters for different push sizes, directions,and locations. The performance of each controller is shown in response to different external pushes. By comparing the capabilities of handling disturbances in each strategy, the contributions of every joint to standing balance are also explored.

  8. JK '98: Acting responsibly

    International Nuclear Information System (INIS)

    For the first time, a paper delivered at the Annual Nuclear Conference was presented by two authors, the CEO of Bayernwerk AG, Dr. Otto Majewski, and the CEO of the Power Generation Division (KWU) of Siemens AG, Adolf Huettl, reflecting the operators' and the vendors' points of view about the present situation of nuclear power use in Germany and the need to maintain its share in the energy mix. The events associated with shipments of casks for radioactive waste have rekindled the debate about the responsibility of the peaceful use of nuclear power in the nuclear opposition camp. That debate needs to be put back on a factual basis. If no consensus could be achieved now about the use of nuclear power as a whole, at least consensus had to be reached about the future approach to spent fuel and waste management. From the outset, the nuclear industry has shown a high degree of responsibility, developing concepts of using uranium as an energy source in an economically viable and responsible way. It is showing responsibility also in making provision for the future. The safe and economically successful operation of today's nuclear power plants is an important reason for developing new reactor concepts. That development of new rector lines depends critically on the preservation and advancement of specialized knowledge. Know-how needs to be preserved and developed further not only for future nuclear power plants but also for the plants existing now, which still have service lives of several decades. Sustainable energy supply requires all sources of energy to be exploited, especially those which do not generate carbon dioxide. All the options currently known must be kept open and preserved, respectively, for coming generations. Acting responsibly means adding to the choices available. (orig.)

In many countries, debate regarding euthanasia is more centered in its convenience, social acceptability and how it is regulated, than in its substantial legitimacy. Some argue that euthanasia should be included as part of clinical practice of health professionals, grounded on individual's autonomy claims-everyone having the liberty to choose how to live and how to die. Against this, others sustain that life has a higher value than autonomy, exercising autonomy without respecting the right to life would become a serious moral and social problem. Likewise, euthanasia supporters some-times claim a 'right to live with dignity', which must be understood as a personal obligation, referred more to the ethical than to the strictly legal sphere. In countries where it is already legalized, euthanasia practice has extended to cases where it is not the patient who requests this but the family or some healthcare professional, or even the legal system-when they think that the patient is living in a condition which is not worthy to live. Generalization of euthanasia possibly will end in affecting those who need more care, such as elder, chronically ill or dying people, damaging severely personal basic rights. Nature, purpose and tradition of medicine rule out the practice of euthanasia, which ought not be considered a medical act or legitimately compulsory for physicians. Today's medicine counts with effective treatments for pain and suffering, such as palliative care, including sedative therapy, which best preserves persons dignity and keeps safe the ethos of the medical profession.

    The prevalence of obesity is increasing in most parts of the world and becoming one of the major global public health problems.Although the components of energy balance have not been adequately estimated over time,available evidence suggests that the increase in obesity is the result of reduced physical activity.Increases in physical activity have been showen to be strongly associated with improving physical fitness and body composition,with probably a positive effect on resting metabolic rate.The Surgeon General's Report on physical Activity and Health advocates that 30 min of regular,moderate-intensity physical activity is associated with decreases in the risk of chronic diseases and may contribute to quality of life.However,the small changes that contribute 10 min for 3 times a day for 3 times a day for aerobic training,or one set instead of three sets of repetitions on resistance training will provide individuals training,or one set instead of three sets of repetitions on resistance training will provide individuals with health benefits.Indeed,nutrition and physical activity should be considered an integral part of fitness and good health,and should be encouraged in all age groups,particularly early in life,The question is no longer centerd around the health benefit of increasing physical activity,but rather creating self awareness and behavior changes in individuals,Hence,effective intervention programs are needed that foster long term changes in physical activity.Among various interventions,the Nutrifit program was recently conducted in Thailand and found to improve health related fitness in children,The development of more effective interventions and approaches is a major challege in this field today.

    Glacier mass-balance parameters such as the equilibrium-line altitude (ELA) play an important role when working with large glacier samples. While the number of observational mass-balance series to derive such parameters is limited, more and more modeled data are becoming available. Here we explore the possibilities of analyzing such ‘synthetic’ mass-balance data with respect to mass-balance parameters. A simplified energy-balance model is driven by bias-corrected regional climate model output...

  15. INVESTIGATION INTO EFFECT OF SPRING PRESSURE ON PERFORMANCE OF BALANCED MECHANICAL SEALS

    Institute of Scientific and Technical Information of China (English)

    SUN Jianjun; GU Boqin

    2007-01-01

    The loads acting on the sealing elements of balanced mechanical seals are analyzed. When the balance factor approaches the back pressure factor, the spring pressure will become main part of the face pressure. The leakage model of balanced mechanical seals is established on the base of M-B model for rough surface. Several GY-70 type balanced mechanical seals are tested. The influences of the spring pressure both on the leakage rate and on the friction characteristic of balanced mechanical seals are investigated. The research results indicate that as spring pressure increases, both the clearance between two end faces and the leakage rate will decrease, and the friction will be more serious because lubrication medium between the rotating ring and the stationary ring reduces, though the increase of the spring pressure may not be enough to change the face friction state of mechanical seals. There exists an optimum spring pressure for mechanical seal operation. Under this spring pressure, not only leakage rate is small, but also the seal end surfaces have a fine friction characteristic.Under different operating conditions, identical type mechanical seals may possess different spring pressure. Appropriate selection of spring pressure is valuable to realize long-period and small leakage rate operating of balanced mechanical seals.

  16. Development of 3-COMPONENT Force-Moment Balance for Low Speed Water Tunnel

    Science.gov (United States)

    Lee, C. S.; Wong, N. L.; Srigrarom, S.; Nguyen, N. T.

    An effort is made to develop a new 3-component force-moment balance, which is capable of measuring lift force, drag force and pitching moment of a model mounted in the water tunnel. The concept used in the balance design is the bending- beam principle. The forces acting on the spring element cause strains on its surface, which are measured by strain gauges. Since strain yielded by the axial force is usually very small, therefore it is not practical to measure axial force using strain gauge directly to sense the strain in axial direction. The main idea of the new balance design is to translate all desired forces (lift and drag) in such a way that they yield bending strain at selected strain-gauge station. This is done by using a bending balance geometry. Under this apparatus, the model wing is mounted at one of its end to the bending balance. The corresponding Lift, Drag forces and Pitching moment are translated into moments at the other end of the balance, and can be measured from sets of strain gauges in bending mode (twisting mode for pitching moment). Example readings are presented in this paper.

  17. Introduction To Application Server Load Balancer

    Full Text Available Now a day’s, everything is going online. And most of the work is done on internet. So, web applications plays vital role on internet to provide 24*7 services to customers. When application becomes popular, traffic to that is also in a state of growing. For availability, scalability, performances boosting more and more servers are required. Load balancing is a key issue in these types of large scale situation. Load balancing is to achieve optimal resource utilization, maximize throughput, minimize response time, and avoid overload. In many scenarios, however, it’s not simply a matter of distributing traffic equally across many servers once deploys; other factors can come into play. Here we studied different load balancing strategies, algorithms, methods and investigate the comparative behavior of load balancing with different parameters. The growing autonomy of servers’ significantly deteriorates the performance of traditional load-balancing so; idea is to implement application load balancer by using Dynamic load balancing method.

    During last years, energy crops have been envisaged as an interesting alternative to biomass residues utilization as renewable energy source. In this work, main parameters used in calculating the energy balance of an energy crop are analyzed. The approach consists of determining energy equivalents for the different inputs and outputs of the process, thus obtaining energy ratios of the system, useful to determine if the energy balance is positive, that is, if the system generates energy. Energy costs for inputs and assessment approaches for energy crop yields (output) are provided. Finally, as a way of illustration, energy balances of some representative energy crops are shown.

    Ferris, A. T.

    1983-01-01

    One-piece strain gage force balances were developed for use in the National Transonic Facility (NTF). This was accomplished by studying the effects of the cryogenic environment on materials, strain gages, cements, solders, and moisture proofing agents, and selecting those that minimized strain gage output changes due to temperature. In addition, because of the higher loads that may be imposed by the NTF, these balances are designed to carry a larger load for a given diameter than conventional balances. Full cryogenic calibrations were accomplished, and wind tunnel results that were obtained from the Langley 0-3-Meter Transonic Cryogenic Tunnel were used to verify laboratory test results.

  16. Act local, think global

    International Nuclear Information System (INIS)

    Tip O'Neill, one of the grand old men of modem US politics, once famously remarked that all politics is local. Like most politicians who succeed on the national stage - and not just in the US - it was a truth he never lost sight of. What is true for politicians is equally true in the communications business. We may increasingly live in a global village, but successful companies - even multi-nationals - forget the importance of local and regional public relations at their peril. Think of Douglas Ivester, the CEO of Coca-Cola at the time of the 1999 Belgian contamination scandal, who allegedly reacted to first reports of the crisis by asking: 'Where the hell is Belgium?' A more appropriate question today - several years after Coke's share price toppled and the CEO was unceremoniously sacked - might be: 'Who the hell is Douglas Nester?' But - to adapt another famous phrase - the fact that communications (and marketing) professionals still need to 'act local' as much as ever before should not blind us to the growing need to 'think global'. In the nuclear industry, as in the world economy generally, increasing global integration is a reality, as are the international nature of the news media and the increasingly global nature of the anti-nuclear pressure groups. Indeed, it was the growing need for a truly global information network to counter these trends, by increasing the overall speed and accuracy of the worldwide nuclear information flow, that led the nuclear community to establish NucNet in 1991. So where exactly is the line between local and regional nuclear communications on the one hand, and global communications on the other? Is there one spin for a regional audience, and another for a global audience? This presentation proposes some guiding principles, by examining the response of nuclear communicators world-wide to the new communications agenda imposed in the wake of the September 11th suicide attacks in the US.

  17. Fixation properties of subdivided populations with balancing selection.

    Science.gov (United States)

    Lombardo, Pierangelo; Gambassi, Andrea; Dall'Asta, Luca

    2015-03-01

    In subdivided populations, migration acts together with selection and genetic drift and determines their evolution. Building upon a recently proposed method, which hinges on the emergence of a time scale separation between local and global dynamics, we study the fixation properties of subdivided populations in the presence of balancing selection. The approximation implied by the method is accurate when the effective selection strength is small and the number of subpopulations is large. In particular, it predicts a phase transition between species coexistence and biodiversity loss in the infinite-size limit and, in finite populations, a nonmonotonic dependence of the mean fixation time on the migration rate. In order to investigate the fixation properties of the subdivided population for stronger selection, we introduce an effective coarser description of the dynamics in terms of a voter model with intermediate states, which highlights the basic mechanisms driving the evolutionary process.

  18. Surface Mass Balance of the Columbia Glacier, Alaska, 1978 and 2010 Balance Years

    O'Neel, Shad

    2012-01-01

    Although Columbia Glacier is one of the largest sources of glacier mass loss in Alaska, surface mass balance measurements are sparse, with only a single data set available from 1978. The dearth of surface mass-balance data prohibits partitioning of the total mass losses between dynamics and surface forcing; however, the accurate inclusion of calving glaciers into predictive models requires both dynamic and climatic forcing of total mass balance. During 2010, the U.S. Geological Survey collected surface balance data at several locations distributed over the surface of Columbia Glacier to estimate the glacier-wide annual balance for balance year 2010 using the 2007 area-altitude distribution. This report also summarizes data collected in 1978, calculates the 1978 annual surface balance, and uses these observations to constrain the 2010 values, particularly the shape of the balance profile. Both years exhibit balances indicative of near-equilibrium surface mass-balance conditions, and demonstrate the importance of dynamic processes during the rapid retreat.

  19. Glioma Association and Balancing Selection of ZFPM2.

    Directory of Open Access Journals (Sweden)

    Shui-Ying Tsang

    Full Text Available ZFPM2, encoding a zinc finger protein and abundantly expressed in the brain, uterus and smooth muscles, plays important roles in cardiac and gonadal development. Abnormal expression of ZFPM2 in ovarian tumors and neuroblastoma has been reported but hitherto its genetic association with cancer and effects on gliomas have not been studied. In the present study, the hexamer insertion-deletion polymorphism rs71305152, located within a large haplotype block spanning intron 1 to intron 3 of ZFPM2, was genotyped in Chinese cohorts of glioma (n = 350, non-glioma cancer (n = 354 and healthy control (n = 463 by direct sequencing and length polymorphism in gel electrophoresis, and ZFPM2 expression in glioma tissues (n = 69 of different grades was quantified by real-time RT-PCR. Moreover, potential natural selection pressure acting on the gene was investigated. Disease-association analysis showed that the overall genotype of rs71305152 was significantly associated with gliomas (P = 0.016, and the heterozygous genotype compared to the combined homozygous genotypes was less frequent in gliomas than in controls (P = 0.005 or non-glioma cancers (P = 0.020. ZFPM2 mRNA expression was negatively correlated with the grades of gliomas (P = 0.002, with higher expression levels in the low-grade gliomas. In the astrocytoma subtype, higher ZFPM2 expression was also correlated with the rs71305152 heterozygous genotype (P = 0.028. In addition, summary statistics tests gave highly positive values, demonstrating that the gene is under the influence of balancing selection. These findings suggest that ZFPM2 is a glioma susceptibility gene, its genotype and expression showing associations with incidence and severity, respectively. Moreover, the balancing selection acting on ZFPM2 may be related to the important roles it has to play in multiple organ development or associated disease etiology.

  1. Amylin-mediated control of glycemia, energy balance, and cognition.

    Science.gov (United States)

    Mietlicki-Baase, Elizabeth G

    2016-08-01

    Amylin, a peptide hormone produced in the pancreas and in the brain, has well-established physiological roles in glycemic regulation and energy balance control. It improves postprandial blood glucose levels by suppressing gastric emptying and glucagon secretion; these beneficial effects have led to the FDA-approved use of the amylin analog pramlintide in the treatment of diabetes mellitus. Amylin also acts centrally as a satiation signal, reducing food intake and body weight. The ability of amylin to promote negative energy balance, along with its unique capacity to cooperatively facilitate or enhance the intake- and body weight-suppressive effects of other neuroendocrine signals like leptin, have made amylin a leading target for the development of novel pharmacotherapies for the treatment of obesity. In addition to these more widely studied effects, a growing body of literature suggests that amylin may play a role in processes related to cognition, including the neurodegeneration and cognitive deficits associated with Alzheimer's disease (AD). Although the function of amylin in AD is still unclear, intriguing recent reports indicate that amylin may improve cognitive ability and reduce hallmarks of neurodegeneration in the brain. The frequent comorbidity of diabetes mellitus and obesity, as well as the increased risk for and occurrence of AD associated with these metabolic diseases, suggests that amylin-based pharmaceutical strategies may provide multiple therapeutic benefits. This review will discuss the known effects of amylin on glycemic regulation, energy balance control, and cognitive/motivational processes. Particular focus will be devoted to the current and/or potential future clinical use of amylin pharmacotherapies for the treatment of diseases in each of these realms. PMID:26922873

    CERN Document Server

    Siripon, N

    2002-01-01

    The research presented in this thesis is on the application of the injection-locked oscillator technique to microwave balanced oscillators. The balanced oscillator design is primarily analysed using the extended resonance technique. A transmission line is connected between the two active devices, so that the active device resonate each other. The electrical length of the transmission line is also analysed for the balanced oscillation condition. The balanced oscillator can be viewed with the negative resistance model and the feedback model. The former model is characterised at a circuit plane where the feedback network is cut. By using both the negative-resistance oscillator model and the feedback model, the locking range of the oscillator is analysed by extending Kurokawa's theory. This analysis demonstrates the locking range of the injection phenomenon, where the injection frequency is either close to the free-running frequency, close to (1/n) x free-running frequency or close to n x the free-running frequen...

    2016-03-01

    We have developed a torsion balance experiment to test the equivalence principle (EP) which follows the solar attractor approach pioneered by Dicke in the early 1960s. By monitoring the response of a balance arranged as a composition dipole with an azimuthally symmetric mass distribution to the gravitational field produced by the Sun, we search for a diurnal modulation of the balance which would indicate a violation of the EP. Since reporting on the status of this experiment last year, the instrument has begun collecting data at a remote underground site. This talk will cover the design and fundamental sensitivity of the balance, and present the results of preliminary analysis of over 1200 hours of data.

    Mountain glaciers comprise a small and widely distributed fraction of the world's terrestrial ice, yet their rapid losses presently drive a large percentage of the cryosphere's contribution to sea level rise. Regional mass balance assessments are challenging over large glacier populations due to remote and rugged geography, variable response of individual glaciers to climate change, and episodic calving losses from tidewater glaciers. In Alaska, we use airborne altimetry from 116 glaciers to estimate a regional mass balance of −75 ± 11 Gt yr−1 (1994–2013). Our glacier sample is spatially well distributed, yet pervasive variability in mass balances obscures geospatial and climatic relationships. However, for the first time, these data allow the partitioning of regional mass balance by glacier type. We find that tidewater glaciers are losing mass at substantially slower rates than other glaciers in Alaska and collectively contribute to only 6% of the regional mass loss.

  13. Heparanase affects food intake and regulates energy balance in mice.

    Directory of Open Access Journals (Sweden)

    Linda Karlsson-Lindahl

    Full Text Available Mutation of the melanocortin-receptor 4 (MC4R is the most frequent cause of severe obesity in humans. Binding of agouti-related peptide (AgRP to MC4R involves the co-receptor syndecan-3, a heparan sulfate proteoglycan. The proteoglycan can be structurally modified by the enzyme heparanase. Here we tested the hypothesis that heparanase plays a role in food intake behaviour and energy balance regulation by analysing body weight, body composition and food intake in genetically modified mice that either lack or overexpress heparanase. We also assessed food intake and body weight following acute central intracerebroventricular administration of heparanase; such treatment reduced food intake in wildtype mice, an effect that was abolished in mice lacking MC4R. By contrast, heparanase knockout mice on a high-fat diet showed increased food intake and maturity-onset obesity, with up to a 40% increase in body fat. Mice overexpressing heparanase displayed essentially the opposite phenotypes, with a reduced fat mass. These results implicate heparanase in energy balance control via the central melanocortin system. Our data indicate that heparanase acts as a negative modulator of AgRP signaling at MC4R, through cleavage of heparan sulfate chains presumably linked to syndecan-3.

  7. Age effects on mediolateral balance control.

    Directory of Open Access Journals (Sweden)

    L Eduardo Cofré Lizama

    Full Text Available BACKGROUND: Age-related balance impairments, particularly in mediolateral direction (ML may cause falls. Sufficiently sensitive and reliable ML balance tests are, however, lacking. This study is aimed to determine (1 the effect of age on and (2 the reliability of ML balance performance using Center of Mass (CoM tracking. METHODS: Balance performance of 19 young (26±3 years and 19 older (72±5 years adults on ML-CoM tracking tasks was compared. Subjects tracked predictable and unpredictable target displacements at increasing frequencies with their CoM by shifting their weight sideward. Phase-shift (response delay and gain (amplitude difference between the CoM and target in the frequency domain were used to quantify performance. Thirteen older and all young adults were reassessed to determine reliability of balance performance measures. In addition, all older adults performed a series of clinical balance tests and conventional posturography was done in a sub-sample. RESULTS: Phase-shift and gain dropped below pre-determined thresholds (-90 degrees and 0.5 at lower frequencies in the older adults and were even lower below these frequencies than in young adults. Performance measures showed good to excellent reliability in both groups. All clinical scores were close to the maximum and no age effect was found using posturography. ML balance performance measures exhibited small but systematic between-session differences indicative of learning. CONCLUSIONS: The ability to accurately perform ML-CoM tracking deteriorates with age. ML-CoM tracking tasks form a reliable tool to assess ML balance in young and older adults and are more sensitive to age-related impairment than posturography and clinical tests.

    2012-10-01

    Full Text Available Background and Aim: The somatosensory system is one of the most effective systems in balance control. It consists of peripheral and central components. Knowing the role of these components in balance control assists the developing of effective rehabilitation protocols. In some diseases peripheral components and in others central components are impaired. This paper reviews the effect of impairment of peripheral and central components of the somatosensory system on balance control.Methods: In this study publication about somatosensory impairments from 1983 through 2011 in PubMed, Scopus, ProQuest, Google Scholar, Iran Medex, Iran Doc and Magiran were reviewed. Medical subject headings terms and keywords related to balance, somatosensory, somatosensory loss, and sensory integration/processing were used to perform the searches.Conclusion: Somatosensory impairments either with peripheral or central origin, can cause problems in balance control. However, these problems are not considered in some patients. In these impairments, balance training is recommended to be used alongside other routine treatments in the patients' rehabilitation programs.

  16. Development of a Common Nordic Balance Settlement

    International Nuclear Information System (INIS)

    NordREG finds it essential for the customers that a common integrated end-user electricity market is developed and that all end-users are able to take part in the Nordic market. A common Nordic balance settlement is one important part of such a change. However, attention has to be paid to the comments that a badly designed common system is worse than well-designed national systems. It is thus important that the change to a common balance settlement is so thoroughly investigated that the common system gives a basis for a well-functioning market. An important basis for such a change is an agreed vision for the process: The present different systems for balance settlement shall by the year 2010 be replaced by a common Nordic balance settlement. This means that: It will be possible for a supplier to sell to the whole Nordic market from one legal entity and using only one system for customer management and reporting. The common Nordic balance settlement will be designed in such a way that it contributes to a well functioning market. This means for example that it will be attractive even for small suppliers and some end-users to be balance responsible parties. It is feasible that the first phase is focused on those present differences that are most decisive for fulfilment of the vision. NordREG recommends that the following issues shall be discussed and agreed in co-operation between NordREG, Nordel and relevant stakeholders in the first phase: The definition shall include how the common Nordic balance settlement shall interact with the balance control and the balance regulation of the interconnected power system and the balance settlement between countries performed by the TSOs. The definition should include the cost-base for common Nordic balance settlement in relation to other system responsibility costs. The core activities of system responsibility have also been analyzed by NordREG. It is important to find a balance between inter alia the need for simplicity and the

    2013-02-01

    Full Text Available The sovereign-debt crisis in the European Union has determined the necessity to reform the signal indicators for the analysis of the public finances' sustainability. In this context, many of the developing/emerging countries consider that the informational value provided by the structural budget balance indicator is insufficient, especially during the periods characterized by absorption. The present study suggests the transition from classical structural budget balance (CAB in the structural balance corrected for absorption (CAAB and supports the use of an improved indicator of the structural budget balance with a superior informational relevance for the macro-economic policies decision makers. Based on the economic literature we will demonstrate that the structural budget balance indicator should be improved, in order to also take into consideration the deviation of the current account balance from its sustainable level, particularly in the stage of the economic cycle characterized by high absorption.

    Values of winter snow accumulation and summer snow, firn, and ice ablation were measured at South Cascade Glacier, WA, to determine the winter and net balance for the 1992 balance year. The 1992 winter balance, averaged over the glacier, was 1.91 m, and the net balance was -2.01 m. This extremely negative balance continued a trend of negative balance years beginning in 1977. Air temperature (at 1,615 m and 1,867 m), barometric pressure, precipitation, and runoff from this glacier basin and an adjacent non-glacierized basin were also continuously measured. This report makes all these data, in tabular, graphical, and machine-readable forms, available to users.

    Science.gov (United States)

    2009-01-01

    You may have heard the phrase as difficult as walking and chewing gum as a joking way of referring to something that is not difficult at all. Just walking, however, is not all that simple physiologically speaking. Even standing upright is an undertaking requiring the complex cooperation of multiple motor and sensory systems including vision, the inner ear, somatosensation (sensation from the skin), and proprioception (the sense of the body s parts in relation to each other). The compromised performance of any of these elements can lead to a balance disorder, which in some form affects nearly half of Americans at least once in their lifetimes, from the elderly, to those with neurological or vestibular (inner ear) dysfunction, to athletes with musculoskeletal injuries, to astronauts returning from space. Readjusting to Earth s gravity has a significant impact on an astronaut s ability to balance, a result of the brain switching to a different "model" for interpreting sensory input in normal gravity versus weightlessness. While acclimating, astronauts can experience headaches, motion sickness, and problems with perception. To help ease the transition and study the effects of weightlessness on the body, NASA has conducted many investigations into post-flight balance control, realizing this research can help treat patients with balance disorders on Earth as well. In the 1960s, the NASA-sponsored Man Vehicle Laboratory at the Massachusetts Institute of Technology (MIT) studied the effects of prolonged space flight on astronauts. The lab s work intrigued MIT doctoral candidate Lewis Nashner, who began conducting NASA-funded research on human movement and balance under the supervision of Dr. Larry Young in the MIT Department of Aeronautics and Astronautics. In 1982, Nashner s work resulted in a noninvasive clinical technique for assessing the cooperative systems that allow the body to balance, commonly referred to as computerized dynamic posturography (CDP). CDP employs a

The aim of this study was to investigate the effect of exercise performed on a Nintendo Wii balance board on the balance and lower limb muscle strength in overweight young adults. [Subjects and Methods] Within-subject repeated measures analysis was used. Sixteen young adults (aged 21.87±1.13 years, body mass index 24.15 ± 0.50 kg/m(2)) were recruited. All subjects performed an exercise program on a Wii balance board for 8 weeks (30 min/session, twice a week for 8 weeks). A NeuroCom Balance Master and a hand-held dynamometer were used to measure balance performance and lower limb muscle strength. [Results] According to the comparison of pre- and post-intervention measurements, the Wii balance board exercise program significantly improved the limit of stability parameters. There was also a significant increase in strength of four lower-limb muscle groups: the hip flexor, knee flexor, ankle dorsiflexor and ankle plantarflexor.

    This paper traces the development of Magnetic Suspension and Balance Systems (MSBSs) for use in wind tunnels. The expression MSBS implies a system that can both suspend a model and also measure the forces and moments acting on the model. This avoids the need for any mechanical support of the model. An MSBS uses electromagnets located outside the test section walls to create magnetic fields inside the test section. Measurement of the electrical current flowing in each of the electromagnets can be used to determine the forces and moments acting on the suspended model. An MSBS is capable of supporting a model with an internal magnetized core subject to gravity, aerodynamic, and inertial loads. The model must have a core made of either a permanent magnet, magnetized soft iron, or a solenoid. The position of the suspended body is inherently unstable. A closed-loop control system which includes a position sensing system has to control the position of the body by controlling the applied magnetic fields. This paper includes a discussion of all the known MSBSs and the outlook for larger systems.

    Full Text Available Throughput maximization in a network is one of the major key challenges in wireless LANs (WLANs and it could be achieved when the load of access points (APs is balanced. The AP load in WLANs is very often found to be uneven. To overcome such imbalance of load, a load balancing technique have been proposed. The load balancing techniques commonly require proprietary software or hardware at the user side for controlling the user-AP association. A new load balancing technique by controlling the size of WLAN cells (i.e., AP’s coverage range, which is conceptually similar to cell breathing in cellular networks. The proposed scheme does not require any modification from the user side nor may any changes be required to the IEEE 802.11 standard [1]. It only requires the ability of dynamically changing the transmission power of the AP beacon messages. We develop a newer load balancing algorithm that will find the optimal beacon power settings which will thereon help to minimize the load of the most congested AP. The load may become shared and this may be performed with minimal delay and also maximized throughput is to be achieved.

  13. Tenth act amending the German atomic energy act

    International Nuclear Information System (INIS)

    On January 14, 2009, the German federal government introduced into parliament the 10th Act Amending the Atomic Energy Act. In the first reading in the federal parliament, Federal Minister for the Environment Gabriel emphasized 2 main points: Intensified protection of nuclear facilities and of transports of radioactive substances against unauthorized interventions; transfer by law to the Federal Office for Radiological Protection (BfS) of decommissioning of the Asse mine. Reliability review: The amendment to Sec.12 b of the Atomic Energy Act is to meet the different safety and security conditions after the terrorist attacks on September 11, 2001 in the United States and other terrorist activities afterwards (London, Madrid) also with respect to hazards arising to nuclear facilities and nuclear transports. The bill must be seen in conjunction with the Ordinance on Reliability Reviews under the Atomic Energy Act dated July 1, 1999 which covers reviews of reliability of persons holding special responsibilities. Asse II mine: The competence of the Federal Office for Radiological Protection is achieved by an amendment to Sec.23, Para.1, Number 2, Atomic Energy Act, in which the words ''and for the Asse II mine'' are added after the word ''waste.'' Further proceedings depend on the additional provision in a new Sec.57 b, Atomic Energy Act. Accordingly, the operation and decommissioning of the Asse II mine are subject to the regulations applicable to facilities of the federation pursuant to Sec.9a, Para.3. In this way, Asse II is given the same legal status as the federal waste management facilities. Moreover, it is stipulated that the mine is to be shut down immediately. (orig.)

    The objective of the Water Framework Directive (2000/60/EC) is to assist in the development of management plans that will lead to the sustainable use of water resources in all EU member states. However, defining the degree of sustainability aimed at is not a straightforward task. It requires detailed knowledge of the hydrogeological characteristics of the basin in question, its environmental needs, the amount of human water demand, and the opportunity to construct a proper water balance that describes the behavior of the hydrological system and estimates available water resources. An analysis of the water balance in the Selva basin (Girona, NE Spain) points to the importance of regional groundwater fluxes in satisfying current exploitation rates, and shows that regional scale approaches are often necessary to evaluate water availability. In addition, we discuss the pressures on water resources, and analyze potential actions, based on the water balance results, directed towards achieving sustainable water management in the basin.

  20. The Heider balance and social distance

    2005-01-01

    The Heider balance is a state of a group of people with established mutual relations between them. These relations, friendly or hostile, can be measured in the Bogardus scale of the social distance. In previous works on the Heider balance, these relations have been described with integers 0 and $\\pm1$. Recently we have proposed real numbers instead. Also, differential equations have been used to simulate the time evolution of the relations, which were allowed to vary within a given range. In this work, we investigate an influence of this allowed range on the system dynamics. As a result, we have found that a narrowing of the range of relations leads to a large delay in achieving the Heider balance. Another point is that a slight shift of the initial distribution of the social distance towards friendship can lead to a total elimination of hostility.

    2011-01-01

    This whitepaper describes the load-balancing performance issues that are observed and tackled during the petascaling of the Vlasiator codes. Vlasiator is a Vlasov-hybrid simulation code developed in Finnish Meteorological Institute (FMI). Vlasiator models the communications associated with the spatial grid operated on as a hypergraph and partitions the grid using the parallel hypergraph partitioning scheme (PHG) of the Zoltan partitioning framework. The result of partitioning determines the distribution of grid cells to processors. It is observed that the partitioning phase takes a substantial percentage of the overall computation time. Alternative (graph-partitioning-based) schemes that perform almost as well as the hypergraph partitioning scheme and that require less preprocessing overhead and better balance are proposed and investigated. A comparison in terms of effect on running time, preprocessing overhead and load-balancing quality of Zoltan's PHG, ParMeTiS, and PT-SCOTCH are presented. Test results on ...

    International Nuclear Information System (INIS)

    This is the seventh edition of Trends and Balances to be presented to the staff of Oak Ridge National (ORNL) and other interested parties. Each year at the end of the planning cycle the Laboratory publishes its official planning document, the Institutional Plan. Trends and Balances is brought out as a condensation of that more formal document and is intended to provide a reference to the kinds of plans that have occupied senior laboratory management over the past year. An institution as large as ORNL changes slowly, so some of the information in this document overlaps that contained in the previous edition of Trends and Balances. Much, however, is different. A new section, for example, describes what senior Laboratory management feels are five new directions for science and technology at ORNL. This document is intended to provide new insights into the programs and structure of the Laboratory

    This manuscript reviews design, manufacture, materials, sensors, and data acquisition technologies that may benefit wind tunnel balances for the aerospace research community. Current state-of-the-art practices are used as the benchmark to consider advancements driven by researcher and facility needs. Additive manufacturing is highlighted as a promising alternative technology to conventional fabrication and has the potential to reduce both the cost and time required to manufacture force balances. Material alternatives to maraging steels are reviewed. Sensor technologies including piezoresistive, piezoelectric, surface acoustic wave, and fiber optic are compared to traditional foil based gages to highlight unique opportunities and shared challenges for implementation in wind tunnel environments. Finally, data acquisition systems that could be integrated into force balances are highlighted as a way to simplify the user experience and improve data quality. In summary, a rank ordering is provided to support strategic investment in exploring the technologies reviewed in this manuscript.

    Objective To assess the effect of exercise training by using the Nintendo Wii Fit video game and balance board system on balance and gait in adults with Parkinson disease (PD). Design A prospective interventional cohort study. Setting An outpatient group exercise class. Participants Ten subjects with PD, Hoehn and Yahr stages 2.5 or 3, with a mean age of 67.1 years; 4 men, 6 women. Interventions The subjects participated in supervised group exercise sessions 3 times per week for 8 weeks by practicing 3 different Wii balance board games (marble tracking, skiing, and bubble rafting) adjusted for their individualized function level. The subjects trained for 10 minutes per game, a total of 30 minutes training per session. Main Outcome Measurements Pre-and postexercise training, a physical therapist evaluated subjects’ function by using the Berg Balance Scale, Dynamic Gait Index, and Sharpened Romberg with eyes open and closed. Postural sway was assessed at rest and with tracking tasks by using the Wii balance board. The subjects rated their confidence in balance by using the Activities-specific Balance Confidence scale and depression on the Geriatric Depression Scale. Results Balance as measured by the Berg Balance Scale improved significantly, with an increase of 3.3 points (P = .016). The Dynamic Gait Index improved as well (mean increase, 2.8; P = .004), as did postural sway measured with the balance board (decreased variance in stance with eyes open by 31%; P = .049). Although the Sharpened Romberg with eyes closed increased by 6.85 points and with eyes opened by 3.3 points, improvements neared significance only for eyes closed (P = .07 versus P = .188). There were no significant changes on patient ratings for the Activities-specific Balance Confidence (mean decrease, −1%; P = .922) or the Geriatric Depression Scale (mean increase, 2.2; P = .188). Conclusions An 8-week exercise training class by using the Wii Fit balance board improved selective measures of

    This is the twelfth issue of Energy Balances and Electricity Profiles published by the Statistics Division of the United Nations Secretariat. Like previous issues, this volume presents energy data for selected countries in a format which shows the overall picture of energy production, conversion and consumption for fuels utilised in the country. Such a publication is useful in assessing and analysing production and consumption patterns in detail on an internationally comparable basis. Since it began publishing energy balances, the Statistics Division has adopted the matrix type of overall energy balance that shows energy sources in the columns and energy flows in the rows. The format is described in detail in the technical report entitled Concepts and Methods in Energy Statistics, with Special Reference to Energy Accounts and Balances and is also discussed in the publication, Energy Statistics: A Manual for Developing Countries. The level of detail of this matrix structure takes into account the need for disaggregation of the energy sector and final demand, while at the same time, owing to the limitations in the quantity and quality of the currently available energy information, coverage has to be restricted to the main sectors only. Furthermore, it should be recognized that unlike national energy balances designed for individual countries' various specific needs, the energy balance format of the Statistics Division has to accommodate the whole spectrum of national energy data which it receives from national statistical offices and through official national publications. Inasmuch as information on electricity is generally available in greater detail than that for other energy forms, the Statistics Division decided to present special electricity profiles for an additional group of countries and areas, thereby covering at least part of their energy conversion and consumption activities.

  11. Water balance of Slovenia 1971 - 2000

    International Nuclear Information System (INIS)

    The water is becoming more and more valuable natural resource. The increasing water demand and climate changes are making water a precious and not always available valuable. The water balance is the most appropriate way to make a full overview of water cycle in Slovenia, to find general information about hydrological characteristics of drainage basins, precipitation, evaporation and runoff. The article presents the methodology and the results of the Water balance project of Slovenia. Slovenia has the geographical position at the juncture of 4 main European georegions: The Alps, the Panonian Basin, the Mediterranean and the Dinaric Mountains. This makes the territory very diverse also from a hydrological point of view. Our major watershed divides the precipitation runoff into two watershed areas - the Adriatic Sea and the Black Sea. Due to this watershed almost all the Slovenia's rivers have headwaters in our territory. Water balance is calculation of water inputs and outputs over the defined area. The basic elements of the water balance include all the inflows and outflows for a given basin and serve for the computation of the water regime of a catchment area. It is defined by the parameters precipitation (P), evaporation (E), discharge (Q) and the change of the water reserves (dS). Main results of the water balance elements for the 1971 - 2000 period for Slovenia are: Average annual precipitation in Slovenia is 1579 mm, average annual evapotranspiration is 717 mm and calculated runoff is 862 mm. Compared to water amounts in the World, where the average precipitation is 750 mm, evapotranspiration is 480 mm and runoff is 270 mm, Slovenia shows an abundance of water quantities. Also the runoff coefficient with 55 % is much higher as 36 % of the world. The major questions remain if we are capable to live with this water amounts within the limits of sustainable development and what will be the effects of climate change to water balance.

  12. SELF BALANCING SYSTEM FOR ROTATING MECHANISMS

    Directory of Open Access Journals (Sweden)

    Marco Antonio Meraz

    2005-08-01

    Full Text Available A self balancing system analysis is presented which utilizes freely moving balancing bodies (balls rotating in unison with a rotor to be balanced. Using Lagrange´s Equation, we derive the non-linear equations of motion for an autonomous system with respect to the polar coordinate system. From the equations of motion for the autonomous system, the equilibrium positions and the linear variational equations are obtained by the perturbation method. Because of resistance to motion, eccentricity of race over which the balancing bodies are moving and the influence of external vibrations, it is impossible to attain a complete balance. Based on the variational equations, the dynamic stability of the system in the neighborhood of the equilibrium positions is investigated. The results of the stability analysis provide the design requirements for the self balancing system.Se presenta el análisis de un sistema de autobalance el cual utiliza bolas libres de movimiento rotando con el rotor que será balanceado. Se usa la ecuación de Lagrange para derivar un sistema de ecuaciones no lineales para un sistema autónomo con respecto a un sistema de coordenadas polares. De las ecuaciones de movimiento, se obtienen ecuaciones linealizadas variacionalmente y posiciones de equilibrio por el método de perturbación. A causa de la resistencia al movimiento, la excentricidad y el movimiento de los cuerpos libres que son provocados por la influencia de vibraciones externas, hace imposible obtener un balanceo completo. Basado en el método variacional, se investiga el comportamiento dinámico del sistema en la frontera de la posición de equilibrio. Los resultados del análisis de estabilidad proveen los requerimientos de diseño para el sistema de autobalance.

    2010-01-01

    We investigate relations between different width parameters of graphs, in particular balanced separator number, treewidth, and cycle rank. Our main result states that a graph with balanced separator number k has treewidth at least k but cycle rank at most k(1 + log (n/k)), thus refining the previously known bounds, as stated by Robertson and Seymour (1986) and by Bodlaender et al. (1995). Furthermore, we show that the improved bounds are best possible. Among other results, we also determine the cycle rank of powers of path graphs, thus answering a question recently raised by Novotny et al. (2009).

    Full Text Available The concepts of connectivity and cycle connectivity play an important role in fuzzy graph theory. In this article, cyclic cutvertices, cyclic bridges and cyclically balanced fuzzy graphs are discussed. It is proved that a vertex in a fuzzy graph is a cyclic cutvertex if and only if it is a common vertex of all strong cycles with maximum strength. Also a cyclic cutvertex cannot be a fuzzy endvertex in a fuzzy graph. A characterization of cyclically balanced fuzzy graphs is obtained. Cyclic vertex connectivity and cyclic edge connectivity of fuzzy graphs are also discussed.

    Mass balances usually use a strain gauge that requires an impedance measurement and is susceptible to noise and thermal drift. A piezoelectric balance can be used to measure mass directly by monitoring the voltage developed across the piezoelectric balance, which is linear with weight or it can be used in resonance to produce a frequency change proportional to the mass change (see figure). The piezoelectric actuator/balance is swept in frequency through its fundamental resonance. If a small mass is added to the balance, the resonance frequency shifts down in proportion to the mass. By monitoring the frequency shift, the mass can be determined. This design allows for two independent measurements of mass. Additionally, more than one sample can be verified because this invention allows for each sample to be transported away from the measuring device upon completion of the measurement, if required. A piezoelectric actuator, or many piezoelectric actuators, was placed between the collection plate of the sampling system and the support structure. As the sample mass is added to the plate, the piezoelectrics are stressed, causing them to produce a voltage that is proportional to the mass and acceleration. In addition, a change in mass delta m produces a change in the resonance frequency with delta f proportional to delta m. In a microgravity environment, the spacecraft could be accelerated to produce a force on the piezoelectric actuator that would produce a voltage proportional to the mass and acceleration. Alternatively, the acceleration could be used to force the mass on the plate, and the inertial effects of the mass on the plate would produce a shift in the resonance frequency with the change in frequency related to the mass change. Three prototypes of the mass balance mechanism were developed. These macro-mass balances each consist of a solid base and an APA 60 Cedrat flextensional piezoelectric actuator supporting a measuring plate. A similar structure with 3 APA

  12. Strain-gage balance calibration of a magnetic suspension and balance system

    A load calibration of the NASA 13-in magnetic suspension and balance system (MSBS) is described. The calibration procedure was originally intended to establish the empirical relationship between the coil currents and the external loads (forces and moments) applied to a magnetically suspended calibrator. However, it was discovered that the performance of a strain-gage balance is not affected when subjected to the magnetic environment of the MSBS. The use of strain-gage balances greatly reduces the effort required to perform a current-vs.-load calibration as external loads can be directly inferred from the balance outputs while a calibrator is suspended in MSBS. It is conceivable that in the future such a calibration could become unnecessary, since an even more important application for the use of a strain-gage balance in MSBS environment is the acquisition of precision aerodynamic force and moment data by telemetering the balance outputs from a suspended model/core/balance during wind tunnel tests.

    Taping and bracing are thought to be effective methods in restricting the ankle's joint motion and assisting prevention of injuries. Research evidence suggests that taping and bracing enhance both the mechanical support and the proprioception of the ankle. However, there is little research concerning the influence of taping and bracing on sport performance. Research has mainly examined tasks with demands on the frontal plane. Therefore, the present study examined the effect of taping and bracing on the performance of a task with demands on the frontal plane. A sample of 30 physical education students (Mage=21.9 yr.) performed a balance task requiring estimation of balance and both right and left deviations. The subjects performed the balance task on four different conditions, with tape, with Swede-O (a lace-up, boot style stabilizer), with Aircast (an inflatable cast), and without any stabilizer. There were no significant differences among the conditions. These findings indicate that taping and bracing do not have negative effects on balance in the frontal plane. This study created concerns regarding the appropriate stabilizer for different tasks, bilateral coordination after the application of a stabilizer, and the influence of psychological factors on prevention of injury.

    Full Text Available Sustainability is a trend, which is more seriously discussed on the international and national level. But also companies in the local level are pushed to have strategies and visions, which enable better future for society, our planet and local economy. Sustainability is one of the conditions – it allows companies to implicate social, economic and environmental pillars to the company´s strategy and management. The question, which remains today is, how to measure social, economic and environmental impact on society? And more – how to enable future generations to have the same conditions as we have today? The paper provides format for a possible bridge between current strategic Balanced Scorecard system and future trend of sustainability. One of the special tools, which can be used for measuring sustainability, is Balanced Scorecard (by Kaplan and Norton in 1990s with the complement of sustainable metrics. The paper introduces three possible methods, which can be used by implementing sustainability into the Balanced Scorecard. One of these methods is described in detail. There is a focus on the sustainable indicators included as the fifth area in Balanced Scorecard model.
