    Full Text Available Motor performance deficits of older adults are due to dysfunction at multiple levels. Age-related differences have been documented on executive functions; motor control becomes more reliant on cognitive control mechanisms, including the engagement of the prefrontal cortex (PFC, possibly compensating for age-related sensorimotor declines. Since at functional level the PFC showed the largest age-related differences during discriminative response task, we wonder whether those effects are mainly due to the cognitive difficulty in stimulus discrimination or they could be also detected in a much easier task. In the present study, we measured the association of physical exercise with the PFC activation and response times (RTs using a simple response task (SRT, in which the participants were asked to respond as quickly as possible by manual key-press to visual stimuli. Simultaneous behavioral (RTs and electroencephalographic (EEG recordings were performed on 84 healthy participants aged 19-86 years. The whole sample was divided into three cohorts (young, middle-aged and older; each cohort was further divided into two equal sub-cohorts (exercise and not-exercise based on a self-report questionnaire measuring physical exercise. The EEG signal was segmented in epochs starting 1100 prior to stimulus onset and lasting 2-s. Behavioral results showed age effects, indicating a slowing of RTs with increasing age. The EEG results showed a significant interaction between age and exercise on the activities recorded on the PFC. The results indicates that: a the brain of older adults needs the PFC engagement also to perform elementary task, such as the SRT, while this activity is not necessary in younger adults, b physical exercise could reduce this age-related reliance on extra cognitive control also during the performance of a SRT, and c the activity of the PFC is a sensitive index of the benefits of physical exercise on sensorimotor decline.

    2013-01-01

    Statistics links microscopic and macroscopic phenomena, and requires for this reason a large number of microscopic elements like atoms. The results are values of maximum probability or of averaging. This introduction to statistical physics concentrates on the basic principles, and attempts to explain these in simple terms supplemented by numerous examples. These basic principles include the difference between classical and quantum statistics, a priori probabilities as related to degeneracies, the vital aspect of indistinguishability as compared with distinguishability in classical physics, the differences between conserved and non-conserved elements, the different ways of counting arrangements in the three statistics (Maxwell-Boltzmann, Fermi-Dirac, Bose-Einstein), the difference between maximization of the number of arrangements of elements, and averaging in the Darwin-Fowler method. Significant applications to solids, radiation and electrons in metals are treated in separate chapters, as well as Bose-Eins...

  18. Colloidal Plasmas : Basic physics of colloidal plasmas

    Indian Academy of Sciences (India)

    C B Dwivedi

    2000-11-01

    Colloidal plasma is a distinct class of the impure plasmas with multispecies ionic composition. The distinction lies in the phase distribution of the impurity-ion species. The ability to tailor the electrostatic interactions between these colloidal particles provides a fertile ground for scientists to investigate the fundamental aspects of the Coulomb phase transition behavior. The present contribution will review the basic physics of the charging mechanism of the colloidal particles as well as the physics of the collective normal mode behavior of the general multi-ion species plasmas. Emphasis will be laid on the clarification of the prevailing confusing ideas about distinct qualities of the various acoustic modes, which are likely to exist in colloidal plasmas as well as in normal multi-ion species plasmas. Introductory ideas about the proposed physical models for the Coulomb phase transition in colloidal plasma will also be discussed.

  19. Differential geometry basic notions and physical examples

    CERN Document Server

    Epstein, Marcelo

    2014-01-01

    Differential Geometry offers a concise introduction to some basic notions of modern differential geometry and their applications to solid mechanics and physics. Concepts such as manifolds, groups, fibre bundles and groupoids are first introduced within a purely topological framework. They are shown to be relevant to the description of space-time, configuration spaces of mechanical systems, symmetries in general, microstructure and local and distant symmetries of the constitutive response of continuous media. Once these ideas have been grasped at the topological level, the differential structure needed for the description of physical fields is introduced in terms of differentiable manifolds and principal frame bundles. These mathematical concepts are then illustrated with examples from continuum kinematics, Lagrangian and Hamiltonian mechanics, Cauchy fluxes and dislocation theory. This book will be useful for researchers and graduate students in science and engineering.

  20. Protein Folding: Search for Basic Physical Models

    Directory of Open Access Journals (Sweden)

    Ivan Y. Torshin

    2003-01-01

    Full Text Available How a unique three-dimensional structure is rapidly formed from the linear sequence of a polypeptide is one of the important questions in contemporary science. Apart from biological context of in vivo protein folding (which has been studied only for a few proteins, the roles of the fundamental physical forces in the in vitro folding remain largely unstudied. Despite a degree of success in using descriptions based on statistical and/or thermodynamic approaches, few of the current models explicitly include more basic physical forces (such as electrostatics and Van Der Waals forces. Moreover, the present-day models rarely take into account that the protein folding is, essentially, a rapid process that produces a highly specific architecture. This review considers several physical models that may provide more direct links between sequence and tertiary structure in terms of the physical forces. In particular, elaboration of such simple models is likely to produce extremely effective computational techniques with value for modern genomics.

  1. Basic science behind the cardiovascular benefits of exercise.

    Wilson, Mathew G; Ellison, Georgina M; Cable, N Tim

    2016-01-01

    Cardiorespiratory fitness is a strong predictor of cardiovascular (CV) disease and all-cause mortality, with increases in cardiorespiratory fitness associated with corresponding decreases in CV disease risk. The effects of exercise upon the myocardium and vascular system are dependent upon the frequency, intensity and duration of the exercise itself. Following a prolonged period (≥6 months) of regular intensive exercise in previously untrained individuals, resting and submaximal exercising heart rates are typically 5-20 beats lower, with an increase in stroke volume of ∼20% and enhanced myocardial contractility. Structurally, all four heart chambers increase in volume with mild increases in wall thickness, resulting in greater cardiac mass due to increased myocardial cell size. With this in mind, the present paper aims to review the basic science behind the CV benefits of exercise. Attention will be paid to understanding (1) the relationship between exercise and cardiac remodelling; (2) the cardiac cellular and molecular adaptations in response to exercise, including the examination of molecular mechanisms of physiological cardiac growth and applying these mechanisms to identify new therapeutic targets to prevent or reverse pathological remodelling and heart failure; and (3) vascular adaptations in response to exercise. Finally, this review will briefly examine how to optimise the CV benefits of exercise by considering how much and how intense exercise should be.

  2. On basic equation of statistical physics

    1996-01-01

    Considering that thermodynamic irreversibility, the principle of entropy increase and hydrodynamic equations cannot be derived rigorously and in a unified way from the Liouville equations, the anomalous Langevin equation in Liouville space or its equivalent generalized Liouville equation is proposed as a basic equation of statistical physics. This equation reflects the fact that the law of motion of statistical thermodynamics is stochastic, but not deterministic. From that the nonequilibrium entropy, the principle of entropy increase, the theorem of minimum entropy production and the BBGKY diffusion equation hierarchy have been derived. The hydrodynamic equations, such as the generalized Navier-Stokes equation and the mass drift-diffusion equation, etc. have been derived from the BBGKY diffusion equation hierarchy. This equation has the same equilibrium solution as that of the Liouville equation. All these are unified and rigorous without adding any extra assumption. But it is difficult to prove that th

    On account of the frequency of appearing and character of atherosclerosis cardiac vascular disease, one of the most crucial elements of effective fight against it is preparation of complex preventive programs including as vast number of population as possible. Consequently, Benjamin and Smitch suggested attaching the notion of basic prevention to the standard division into primary and secondary one. The basic prevention, carrying out in the general population, should concern genetic predisposition, psychosocial factors, keeping up proper body weight, healthy eating and physical activity. Especially high hopes are connected with high efficiency, simplicity and low money-consumption of preventive activities associated with physical activity modification, which has a crucial influence on reducing negative impact of atherosclerosis hazard. The results of numerous scientific research, carried out in many countries and on various, large groups, proved undoubtedly that at the healthy adult people of both sex the systematic physical activity of moderate intensification plays an essential part in preventing CVD and decreasing the death risk because of that reason as well. Moreover, systematic physical exercises show many other health-oriented actions, thanks to which they have an influence on decreasing premature and total death rate. The risk of incidence of civilization-related diseases such as diabetes type II, hypertension, obesity, osteoporosis, tumors (of large intestine, breast, prostatic gland) and depression has decreased significantly. Unequivocally positive influence has been proved at many observations dedicated to health recreational physical activity and physical activity connected with professional work based on aerobe effort. The positive effects have been also observed at children population and senior population which is more and more numerous and the most at risk. The beneficial action of physical activity is connected with direct effect on organism

    The paper develops an algorithm that solves economic lot size problem in O(n2) time in the Wagner-Whitin case. The algorithm is based on the standard dynamic programming approach which requires the computation of the maximal relative benefit for some possible subplans of the production plan. In this algorithm the authors have studied the forward property and decomposition properties which can make computation easy. The proposed algorithm appears to perform quite reasonably for practical application.

    With the advance of modern radiation therapy technique, radiation dose conformation and dose distribution have improved dramatically. However, the progress does not completely fulfill the goal of cancer treatment such as improved local control or survival. The discordances with the clinical results are from the biophysical nature of photon, which is the main source of radiation therapy in current field, with the lower linear energy transfer to the target. As part of a natural progression, there recently has been a resurgence of interest in particle therapy, specifically using heavy charged particles, because these kinds of radiations serve theoretical advantages in both biological and physical aspects. The Korean government is to set up a heavy charged particle facility in Korea Institute of Radiological & Medical Sciences. This review introduces some of the elementary physics of the various particles for the sake of Korean radiation oncologists' interest.

  8. The benefits of basic research: advances in reproductive physiology.

    Science.gov (United States)

    1995-06-01

    At the Population Council's Center for Biomedical Research basic research is being conducted on the reproductive system with a view to develop new contraceptive and reproductive health technologies. Research in the Reproductive Physiology Program at the Center is carried out by reproductive endocrinologists, molecular biologists, and biochemists working in eight laboratories. In several of the laboratories the function of hormones that regulate spermatogenesis is studied. Scientists in Milan Bagchi's laboratory have developed a model system, composed of cellular components in a test tube, that allows them to study the full sequence of events involved in signal transduction. In James Catterall's laboratory, scientists study how androgens regulate sexual development at the molecular level. The steroid hormones cortisol and corticosterone play critical roles in mammalian fetal development. Scientists in several laboratories study the function of two specialized testicular cells: the Leydig and Sertoli cells. The Leydig cell synthesizes and secretes testosterone, an androgen that regulates spermatogenesis. The Sertoli cell maintains the environment in which spermatogenesis occurs. Researchers in Glen Gunsalus's laboratory study an androgen-binding protein secreted by the Sertoli cell. In collaboration with scientists at the Shanghai Research Center of Biotechnology, they used advanced genetic techniques to create a biologically active form of the protein in silk worm larvae. Scientists in Patricia Morris's laboratory recently identified molecular signals that control the interactions between developing sperm and Sertoli and Leydig cells. In the laboratory of David Phillips, scientists are investigating how the HIV virus penetrates the outer layer of cells in the genital tract and infects underlying cells. In 1994 a vaginally applied microbicide was developed that may inhibit infection by sexually transmitted diseases including HIV. Applications of basic research such

    Mather, John C.

    2009-01-01

    Dark matter, dark energy, the Big Bang, testing relativity -- all are physics questions accessible to astrophysicists -- but all require new equipment. As Harwit's "Cosmic Discovery" pointed out, almost all great surprises in astronomy came from new equipment or new uses of equipment designed for other purposes, and many of those had military applications. I will outline prospects for new equipment and discuss how that equipment can be developed and built. Bigger and lighter mirrors, wavefront sensing and control, new detector technology, cryogenics -- each has its own social network, its own special possibilities, and its own funding sources outside science. I will discuss some examples drawn from real-life experience with the James Webb Space Telescope, a telescope that was said to have a "giggle factor" when it was proposed in 1995. Now each of the 10 major technologies has been brought to maturity, flight hardware is being built, and launch is planned for 2014. As an instrument builder all my life, I will speculate a little on what may be within our reach over the next few decades.

    2014-01-01

    Previous research demonstrates that physical activity has psychological benefits for people of all ages. However, it is unclear whether people caring for a frail or ill relative would derive similar psychological benefits, considering the potentially stressful caregiver role. This article reviews the current literature describing the effect of physical activity interventions on the psychological status of caregivers. A search from January 1975 to December 2012 identified five intervention studies investigating physical activity and psychological status in caregivers. These focused on female Caucasian caregivers who were older than 60 years. The physical activity interventions improved stress, depression and burden in caregivers, but small sample sizes, short-term follow up and varying results limited the generalizability of the findings. There were few trials investigating male caregivers, and most care-recipients were people with dementia. Studies with caregivers of different ages and gender, with a range of physical activity interventions, are needed to clarify whether physical activity has psychological benefits for caregivers.

    A clear, concise and beautifully written presentation of modern physics. Readers will not only learn physics, they will learn to enjoy it. Self-contained and comprehensive History, concepts and formal treatment go hand-in-hand. Suppresses mathematical technicalities in favor of a wide scope of topics. Suited for class use, e.g. as a textbook for the course ''Modern Physics'', but also ideal for ''lone explorers'' and other newcomers to physics. ''Basic Concepts in Physics: From the Cosmos to Quarks'' is the outcome of the authors' long and varied teaching experience in different countries and for different audiences, and gives an accessible and eminently readable introduction to all the main ideas of modern physics. The book's fresh approach, using a novel combination of historical and conceptual viewpoints, makes it ideal complementary reading to more standard textbooks. The first five chapters are devoted to classical physics, from planetary motion to special relativity, always keeping in mind its relevance to questions of contemporary interest. The next six chapters deal mainly with newer developments in physics, from quantum theory and general relativity to grand unified theories, and the book concludes by discussing the role of physics in living systems. A basic grounding in mathematics is required of the reader, but technicalities are avoided as far as possible; thus complex calculations are omitted so long as the essential ideas remain clear. The book is addressed to undergraduate and graduate students in physics and will also be appreciated by many professional physicists. It will likewise be of interest to students, researchers and teachers of other natural sciences, as well as to engineers, high-school teachers and the curious general reader, who will come to understand what physics is about and how it describes the different phenomena of Nature. Not only will readers of this book learn

    Lasers are increasingly used by plastic surgeons to address issues such as wrinkles and textural changes, skin laxity, hyperpigmentation, vascularity, and excess fat accumulation. A fundamental understanding of the underlying science and physics of laser technology is important for the safe and efficacious use of laser in medical settings. The purpose of this article was to give clinicians with limited exposure to lasers a basic understanding of the underlying science. In that manner, they can confidently make appropriate decisions as to the best device to use on a patient (or the best device to purchase for a practice).

  3. Hadron Physics and QCD: Just the Basic Facts

    Roberts, Craig D

    2015-01-01

    With discovery of the Higgs boson, the Standard Model of Particle Physics became complete. Its formulation is a remarkable story; and the process of verification is continuing, with the most important chapter being the least well understood. Quantum Chromodynamics (QCD) is that part of the Standard Model which is supposed to describe all of nuclear physics and yet, almost fifty years after the discovery of quarks, we are only just beginning to understand how QCD moulds the basic bricks for nuclei: pious, neutrons, protons. QCD is characterized by two emergent phenomena: confinement and dynamical chiral symmetry breaking (DCSB), whose implications are extraordinary. This contribution describes how DCSB, not the Higgs boson, generates more than 98% of the visible mass in the Universe, explains why confinement guarantees that condensates, those quantities that were commonly viewed as constant mass-scales that fill all spacetime, are instead wholly contained within hadrons, and elucidates a range of observable co...

    Equity is one of the essential objectives of the social health insurance. This article evaluates the benefit distribution of the China's Urban Residents' Basic Medical Insurance (URBMI), covering 300 million urban populations. Using the URBMI Household Survey data fielded between 2007 and 2011, we estimate the benefit distribution by the two-part model, and find that the URBMI beneficiaries from lower income groups benefited less than that of higher income groups. In other words, government subsidy that was supposed to promote the universal coverage of health care flew more to the rich. Our study provides new evidence on China's health insurance system reform, and it bears meaningful policy implication for other developing countries facing similar challenges on the way to universal coverage of health insurance.

    Full Text Available Abstract Background Physical inactivity has major impacts on health and productivity. Our aim was to estimate the health and economic benefits of reducing the prevalence of physical inactivity in the 2008 Australian adult population. The economic benefits were estimated as 'opportunity cost savings', which represent resources utilized in the treatment of preventable disease that are potentially available for re-direction to another purpose from fewer incident cases of disease occurring in communities. Methods Simulation models were developed to show the effect of a 10% feasible, reduction target for physical inactivity from current Australian levels (70%. Lifetime cohort health benefits were estimated as fewer incident cases of inactivity-related diseases; deaths; and Disability Adjusted Life Years (DALYs by age and sex. Opportunity costs were estimated as health sector cost impacts, as well as paid and unpaid production gains and leisure impacts from fewer disease events associated with reduced physical inactivity. Workforce production gains were estimated by comparing surveyed participation and absenteeism rates of physically active and inactive adults, and valued using the friction cost approach. The impact of an improvement in health status on unpaid household production and leisure time were modeled from time use survey data, as applied to the exposed and non-exposed population subgroups and valued by suitable proxy. Potential costs associated with interventions to increase physical activity were not included. Multivariable uncertainty analyses and univariate sensitivity analyses were undertaken to provide information on the strength of the conclusions. Results A 10% reduction in physical inactivity would result in 6,000 fewer incident cases of disease, 2,000 fewer deaths, 25,000 fewer DALYs and provide gains in working days (114,000, days of home-based production (180,000 while conferring a AUD96 million reduction in health sector costs

  6. Physical activity benefits and risks on the gastrointestinal system.

    Martin, Donald

    2011-12-01

    This review evaluates the current understanding of the benefits and risks of physical activity and exercise on the gastrointestinal system. A significant portion of endurance athletes are affected by gastrointestinal symptoms, but most symptoms are transient and do not have long-term consequences. Conversely, physical activity may have a protective effect on the gastrointestinal system. There is convincing evidence that physical activity reduces the risk of colon cancer. The evidence is less convincing for gastric and pancreatic cancers, gastroesophageal reflux disease, peptic ulcer disease, nonalcoholic fatty liver disease, cholelithiasis, diverticular disease, irritable bowel syndrome, and constipation. Physical activity may reduce the risk of gastrointestinal bleeding and inflammatory bowel disease, although this has not been proven unequivocally. This article provides a critical review of the evidence-based literature concerning exercise and physical activity effects on the gastrointestinal system and provides physicians with a better understanding of the evidence behind exercise prescriptions for patients with gastrointestinal disorders. Well-designed prospective randomized trials evaluating the risks and benefits of exercise and physical activity on gastrointestinal disorders are recommended for future research.

  7. Basic Physics of Tokamak Transport Final Technical Report.

    Energy Technology Data Exchange (ETDEWEB)

    Sen, Amiya K.

    2014-05-12

    The goal of this grant has been to study the basic physics of various sources of anomalous transport in tokamaks. Anomalous transport in tokamaks continues to be one of the major problems in magnetic fusion research. As a tokamak is not a physics device by design, direct experimental observation and identification of the instabilities responsible for transport, as well as physics studies of the transport in tokamaks, have been difficult and of limited value. It is noted that direct experimental observation, identification and physics study of microinstabilities including ITG, ETG, and trapped electron/ion modes in tokamaks has been very difficult and nearly impossible. The primary reasons are co-existence of many instabilities, their broadband fluctuation spectra, lack of flexibility for parameter scans and absence of good local diagnostics. This has motivated us to study the suspected tokamak instabilities and their transport consequences in a simpler, steady state Columbia Linear Machine (CLM) with collisionless plasma and the flexibility of wide parameter variations. Earlier work as part of this grant was focused on both ITG turbulence, widely believed to be a primary source of ion thermal transport in tokamaks, and the effects of isotope scaling on transport levels. Prior work from our research team has produced and definitively identified both the slab and toroidal branches of this instability and determined the physics criteria for their existence. All the experimentally observed linear physics corroborate well with theoretical predictions. However, one of the large areas of research dealt with turbulent transport results that indicate some significant differences between our experimental results and most theoretical predictions. Latter years of this proposal were focused on anomalous electron transport with a special focus on ETG. There are several advanced tokamak scenarios with internal transport barriers (ITB), when the ion transport is reduced to

  9. Basic Nuclear Physics Research Needs for Nuclear Energy

    Science.gov (United States)

    Hill, Tony

    2008-10-01

    Basic nuclear physics research will play a central role in the development of the future nuclear facilities. Federal requirements for higher efficiencies, lower operating and construction costs, and advanced safeguards can all be impacted by the quality of nuclear data used in the fuel cycle calculations for design and licensing. Uncertainties in the underlying nuclear data propagate to uncertainties in integral and operational parameters, which drive margins and cost. Department of Energy (DOE) programs are underway to help develop the necessary nuclear research infrastructure. The Nuclear Energy office of DOE leads the development of new nuclear energy generation technologies to meet energy and climate change goals and advanced, proliferation resistant nuclear fuel technologies that maximize energy from nuclear fuel, while maintaining and enhancing the national nuclear infrastructure. These activities build on important work started over the last three years to deploy new nuclear plants in the United States by early in the next decade, and to develop advanced, next-generation nuclear technology. In this talk, I will discuss some of the foreseen opportunities and needs for basic nuclear research in nuclear energy.

    2011-03-01

    Full Text Available Objective: To examine the prevalence and determinants of basic and/or attendance benefits among children involved with the child welfare system (CWS.Design: A register study of all children involved with CWS in Norway from 1997-2006.Participants: 96,354 children from the CWS group and 149,030 children who had never been in the CWS as a comparison group.Results: 11% of children involved with CWS received basic and/or attendance benefits compared to 3% in the comparison group. In multivariate logistic regression, the boys’ chances of ever receiving basic and/or attendance benefits were greater than the girls’ chances. The chances of receiving benefits increased nearly four to sixfold as a child becomes older. However, they decrease as the age at debut to CWS increases. It was also revealed that those children who stayed under child welfare for two or more years had an increased chance of ever receiving basic and/or attendance benefits. For children with reported behavioral disorders, the chances of basic and/or attendance benefits were nearly twofold. For children under home-based support and medication interventions, the chances of receiving basic and/or attendance benefits were greater than for children who were not under these interventions.Conclusion: Chronic health conditions that claim basic and/or attendance benefits were more prevalent among children involved with CWS than the general children’s population. This phenomenon may be explained by gender, age, age at debut to CWS, length of stay under CWS, types and reasons for interventions

  11. Physical benefits of dancing for healthy older adults: a review.

    2009-10-01

    Dancing is a mode of physical activity that may allow older adults to improve their physical function, health, and well-being. However, no reviews on the physical benefits of dancing for healthy older adults have been published in the scientific literature. Using relevant databases and keywords, 15 training and 3 cross-sectional studies that met the inclusion criteria were reviewed. Grade B-level evidence indicated that older adults can significantly improve their aerobic power, lower body muscle endurance, strength and flexibility, balance, agility, and gait through dancing. Grade C evidence suggested that dancing might improve older adults' lower body bone-mineral content and muscle power, as well as reduce the prevalence of falls and cardiovascular health risks. Further research is, however, needed to determine the efficacy of different forms of dance, the relative effectiveness of these forms of dance compared with other exercise modes, and how best to engage older adults in dance participation.

    2011-04-01

    Physics constitutes a scientific endeavour that has benefited particularly from the globalization of our planet and the international character of its practitioners. The Medal Award was created by friends of Dwight Nicholson to highlight achievements in humanitarian service, special mentorship of students and junior colleagues while motivating interest in physics in the general public, outreach to the larger community of scientists and nonscientists, and work towards achieving gender and minority equity in the work force. While these are broad goals, they uniquely match the interests of practicing physicists as they weave seamlessly with their scientific work. Examples of the variety of such engagement in the physics community in the present time as well as in the past will be presented.

  13. Particle transport and deposition: basic physics of particle kinetics.

    Tsuda, Akira; Henry, Frank S; Butler, James P

    2013-10-01

    The human body interacts with the environment in many different ways. The lungs interact with the external environment through breathing. The enormously large surface area of the lung with its extremely thin air-blood barrier is exposed to particles suspended in the inhaled air. The particle-lung interaction may cause deleterious effects on health if the inhaled pollutant aerosols are toxic. Conversely, this interaction can be beneficial for disease treatment if the inhaled particles are therapeutic aerosolized drugs. In either case, an accurate estimation of dose and sites of deposition in the respiratory tract is fundamental to understanding subsequent biological response, and the basic physics of particle motion and engineering knowledge needed to understand these subjects is the topic of this article. A large portion of this article deals with three fundamental areas necessary to the understanding of particle transport and deposition in the respiratory tract. These are: (i) the physical characteristics of particles, (ii) particle behavior in gas flow, and (iii) gas-flow patterns in the respiratory tract. Other areas, such as particle transport in the developing lung and in the diseased lung are also considered. The article concludes with a summary and a brief discussion of areas of future research.

    O'Connor, Brian P; Rousseau, Francois L; Maki, Susan Anneli

    2004-01-01

    Self-reports of levels of physical exercise, experienced bodily changes, and attitudinal and well-being variables were obtained from 407 adults, aged 26 to 95 years. The purpose was to assess the relative magnitudes of the experienced benefits of exercise across the exercise continuum. Cluster analyses identified three groups at each of four age levels: a) sedentary people who experienced negative bodily changes; b) modest exercisers who reported the most positive bodily changes; and c) high exercisers who reported only minimal bodily changes. Psychological barriers to exercise among sedentary people included negative exercise attitudes, attributions of negative bodily changes to aging, and low levels of exercise motivation and self-efficacy. Modest and high exercisers both scored high on attitude and well-being variables.

  15. Science Awareness and Science Literacy through the Basic Physics Course: Physics with a bit of Metaphysics?

    Science.gov (United States)

    Rusli, Aloysius

    2016-08-01

    Until the 1980s, it is well known and practiced in Indonesian Basic Physics courses, to present physics by its effective technicalities: The ideally elastic spring, the pulley and moving blocks, the thermodynamics of ideal engine models, theoretical electrostatics and electrodynamics with model capacitors and inductors, wave behavior and its various superpositions, and hopefully closed with a modern physics description. A different approach was then also experimented with, using the Hobson and Moore texts, stressing the alternative aim of fostering awareness, not just mastery, of science and the scientific method. This is hypothesized to be more in line with the changed attitude of the so-called Millenials cohort who are less attentive if not interested, and are more used to multi-tasking which suits their shorter span of attention. The upside is increased awareness of science and the scientific method. The downside is that they are getting less experience of the scientific method which intensely bases itself on critical observation, analytic thinking to set up conclusions or hypotheses, and checking consistency of the hypotheses with measured data. Another aspect is recognition that the human person encompasses both the reasoning capacity and the mental- spiritual-cultural capacity. This is considered essential, as the world grows even smaller due to increased communication capacity, causing strong interactions, nonlinear effects, and showing that value systems become more challenging and challenged due to physics / science and its cosmology, which is successfully based on the scientific method. So students should be made aware of the common basis of these two capacities: the assumptions, the reasoning capacity and the consistency assumption. This shows that the limits of science are their set of basic quantifiable assumptions, and the limits of the mental-spiritual-cultural aspects of life are their set of basic metaphysical (non-quantifiable) assumptions.

    Full Text Available Formaldehyde is the widely employed fixative that has been studied for decades. The chemistry of fixation has been studied widely since the early 20 th century. However, very few studies have been focused on the actual physics/chemistry aspect of process of this fixation. This article attempts to explain the chemistry of formaldehyde fixation and also to study the physical aspects involved in the fixation. The factors involved in the fixation process are discussed using well documented mathematical and physical formulae. The deeper understanding of these factors will enable pathologist to optimize the factors and use them in their favor.

    2013-07-14

    Amphiphiles, either synthetic or natural, are structurally simple molecules with the unprecedented capacity to self-assemble into complex, hierarchical geometries in nanospace. Effective self-assembly processes of amphiphiles are often used to mimic biological systems, such as assembly of lipids and proteins, which has paved a way for bottom-up nanotechnology with bio-like advanced functions. Recent developments in nanostructure formation combine simple processes of assembly with the more advanced concept of nanoarchitectonics. In this perspective, we summarize research on self-assembly of amphiphilic molecules such as lipids, surfactants or block copolymers that are a focus of interest for many colloid, polymer, and materials scientists and which have become increasingly important in emerging nanotechnology and practical applications, latter of which are often accomplished by amphiphile-like polymers. Because the fundamental science of amphiphiles was initially developed for their solution assembly then transferred to assemblies on surfaces as a development of nanotechnological techniques, this perspective attempts to mirror this development by introducing solution systems and progressing to interfacial systems, which are roughly categorized as (i) basic properties of amphiphiles, (ii) self-assembly of amphiphiles in bulk phases, (iii) assembly on static surfaces, (iv) assembly at dynamic interfaces, and (v) advanced topics from simulation to application. This progression also represents the evolution of amphiphile science and technology from simple assemblies to advanced assemblies to nanoarchitectonics.

  8. Superallowed nuclear beta decay: Precision measurements for basic physics

    2012-11-20

    For 60 years, superallowed 0{sup +}{yields}0{sup +} nuclear beta decay has been used to probe the weak interaction, currently verifying the conservation of the vector current (CVC) to high precision ({+-}0.01%) and anchoring the most demanding available test of the unitarity of the Cabibbo-Kobayashi-Maskawa (CKM) matrix ({+-}0.06%), a fundamental pillar of the electroweak standard model. Each superallowed transition is characterized by its ft-value, a result obtained from three measured quantities: the total decay energy of the transition, its branching ratio, and the half-life of the parent state. Today's data set is composed of some 150 independent measurements of 13 separate superallowed transitions covering a wide range of parent nuclei from {sup 10}C to {sup 74}Rb. Excellent consistency among the average results for all 13 transitions - a prediction of CVC - also confirms the validity of the small transition-dependent theoretical corrections that have been applied to account for isospin symmetry breaking. With CVC consistency established, the value of the vector coupling constant, G{sub V}, has been extracted from the data and used to determine the top left element of the CKM matrix, V{sub ud}. With this result the top-row unitarity test of the CKM matrix yields the value 0.99995(61), a result that sets a tight limit on possible new physics beyond the standard model. To have any impact on these fundamental weak-interaction tests, any measurement must be made with a precision of 0.1% or better - a substantial experimental challenge well beyond the requirements of most nuclear physics measurements. I overview the current state of the field and outline some of the requirements that need to be met by experimentalists if they aim to make measurements with this high level of precision.

    Sinha-Ray, S.; Yarin, A. L.; Pourdeyhimi, B.

    2010-08-01

    The work aims at the experimental and theoretical study of the mechanism of meltblowing. Meltblowing is a popular method of producing polymer microfibers and nanofibers en masse in the form of nonwovens via aerodynamic blowing of polymer melt jets. However, its physical aspects are still not fully understood. The process involves a complex interplay of the aerodynamics of turbulent gas jets with strong elongational flows of polymer melts, none of them fully uncovered and explained. To evaluate the role of turbulent pulsations (produced by turbulent eddies in the gas jet) in meltblowing, we studied first a model experimental situation where solid flexible sewing threadlines were subjected to parallel high speed gas jet. After that a comprehensive theory of meltblowing is developed, which encompasses the effects of the distributed drag and lift forces, as well as turbulent pulsations acting on polymer jets, which undergo, as a result, severe bending instability leading to strong stretching and thinning. Linearized theory of bending perturbation propagation over threadlines and polymer jets in meltblowing is given and some successful comparisons with the experimental data are demonstrated.

    2015-06-01

    Full Text Available Nowadays, physical activity is an extremely important segment of a healthy lifestyle not only for children but also for adults. Technological advances allow us to reach our goals with much less physical effort than was required of the individual in the past. Additionally, the fast pace of life and an increasingly sedentary lifestyle also contribute to reduced physical activity among the population. Analysis of published scientific articles in the field of physical activity among basic school students includes 15 research studies. They were included regardless of the origin of the publication and citation frequency. It can be seen that the most common segment of research in children’s physical activity is the gender perspective. Researchers are further interested in the effects of age, educational success, BMI, place of residence, frequency and time spent in physical activity, education and physical activity of parents, as well as the level of organization (organized / unorganized activity. Therefore it can be concluded that children’s physical activities are influenced by external and internal factors. Analysis of published research has shown that physical activity depends upon many internal and external factors. A higher level of physical activity is often detected with boys and children in urban areas, compared to rural ones. Physically active parents have physically more active children. A higher proportion of interviewed basic school students was found to participate in organized forms of exercise in comparison to the unorganized ones.

    2015-01-01

    Aside from numerical algorithms and problem setup, large-scale physics simulations on distributed-memory supercomputers require more basic utilitarian functionality, such as physical units and constants; display to the screen or standard output device; message passing; I/O to disk; and runtime parameter management and usage statistics. Here we describe and make available Fortran 2003 classes furnishing extensible object-oriented implementations of this sort of rudimentary functionality, along with individual `unit test' programs and larger example problems demonstrating their use. These classes compose the Basics division of our developing astrophysics simulation code GenASiS (General Astrophysical Simulation System), but their fundamental nature makes them useful for physics simulations in many fields.

    Full Text Available Computer technology has become an integral part of physical education, yet there have been few studies exploring the use of multimedia technology in the instruction of Physical Education. The purpose of this study was to investigate if multimedia technology affected the learning of basic ballet skills. A total of 32 female students, mean age 18.1 years, studying at the Faculty of Physical Education Zagazig university were divided into two groups. The experimental group comprised 16 students. Participants in this group participated in a ballet class with multimedia technology for six weeks. Group two participated in the ballet class with the traditional method as the control group. Parameters assessed height, weight, age, and academic level. All participants were free of any disorders known to affect performance, such as bone fractures, osteoporosis, diabetes, or cardiovascular disease. Participants reported no use of anti-seizure drugs or alcohol. In addition, all participants were fully informed of the aims of the study, and gave their voluntary consent prior to participation. The measurement procedures were in accordance with ethical human experimentation. All statistical analyses were calculated with the SPSS statistical package. Results indicated significant differences between the two groups in learning the basic skills and levels of knowledge of ballet. Applying the proposed educational program meant using multimedia to teach basic ballet skills to second-year female students enrolled in the Faculty of Physical Education

    2014-11-01

    Current guidelines recommend children accumulate 60 min of daily physical activity; however, highly publicized sudden-death events among young athletes raise questions regarding activity safety. An expert group convened (June 2012) to consider the safety of promoting increased physical activity for children, and recommended the publication of an evidence-based statement of current knowledge regarding the benefits and risks of physical activity for children. Recommendations for encouraging physical activity while maximizing the opportunity to identify children who have been prescribed a physical activity restriction include (1) professionals and (or) researchers that encourage children to change the type of physical activity or to increase the frequency, intensity, or duration of their activity should inquire whether a child has primary healthcare provider-prescribed activity limitations before the child's activity participation changes; (2) physical activity researchers should prioritize the development of evidence regarding the benefits and risks of childhood physical activity and inactivity, particularly data on the risks of sedentary lifestyles and physical activity-associated injury risks that accounts for the amount of activity performed, and the effectiveness of current risk-management strategies and screening approaches; (3) professionals and researchers should prioritize the dissemination of information regarding the benefits of physical activity and the risks of sedentary behaviour in children; and (4) parents and professionals should encourage all children to accumulate at least 60 min of physical activity daily. The recommendations are established as a minimum acceptable standard that is applicable to all physical activity opportunities organized for children, whether those opportunities occur in a community, school, or research setting.

    2013-05-01

    Neurovascular imaging studies are routinely used for the assessment of headaches and changes in mental status, stroke workup, and evaluation of the arteriovenous structures of the head and neck. These imaging studies are being performed with greater frequency as the aging population continues to increase. Magnetic resonance (MR) angiographic imaging techniques are helpful in this setting. However, mastering these techniques requires an in-depth understanding of the basic principles of physics, complex flow patterns, and the correlation of MR angiographic findings with conventional MR imaging findings. More than one imaging technique may be used to solve difficult cases, with each technique contributing unique information. Unfortunately, incorporating findings obtained with multiple imaging modalities may add to the diagnostic challenge. To ensure diagnostic accuracy, it is essential that the radiologist carefully evaluate the details provided by these modalities in light of basic physics principles, the fundamentals of various imaging techniques, and common neurovascular imaging pitfalls.

    Winkler, S.; Tintrup Gen. Suntrup, A.

    2009-04-01

    Due to an increasing disproportion between experienced teaching staff and student numbers at German universities, the time available for teaching the fundamental basic knowledge in Physical Geography was condensed during the past decade. Unfortunately, this mainly has been achieved at the expense of practical lessons of testing student's knowledge. The recent introduction of the Bachelor/Master degree has not solved this problem, but rather accelerated that tend. The "losers" of this tendency are those students enrolled in trainee teacher studies in Geography. In conjunction with the recent modifications of the study programs putting more focus on applied or specialized fields of Geography and its methodology, the trainee teacher students often express their critics and urgently demand opportunities to improve and test their basic knowledge (because it is especially that knowledge, they need at school and for their traditional examination). As the study program is quite dense, there is no room for special courses or seminars. By contrast, one has to use some free time slots available e.g. in the evenings of the usually quite long German excursions or of weekend seminars. However, after a day in the field or in the classroom, the teacher has to find a method owing enough excitement and clearly visible benefit for the students to achieve sufficient motivation. Interactive geographic-didactical games have been developed exclusively for this purpose and applied at different occasions. Those games had the goal of testing student's basic knowledge in a rather unconventional and "casual" style in order to motivate active participation. Most of the games could be played in small groups of students with the teacher only occasionally being involved as referee. Of course, the games had the general aim of improving the basic knowledge - or at least give the students the possibility to discover their own strength (or weakness) just before it is too late (as it e.g. would be

    2012-01-01

    In this review, we identify the health benefits associated with physical activity (PA); address the physical activity and sedentary guidelines issued by public health scientists as well as children's compliance to these guidelines; discuss the importance of motor skill acquisition during early childhood; and identify different settings that contribute to physical activity participation and strategies for improving PA in these settings. Results show that regular participation in PA during childhood has numerous immediate benefits, including positive changes in adiposity, skeletal health, psychological health, and cardiorespiratory fitness. Additionally, motor skill development during early childhood may have immediate health benefits as well as long-lasting effects in adulthood. Furthermore, the benefits of PA during childhood also appear to positively influence adult health outcomes, such as increased bone mineral density. Key environmental settings that have been shown to influence children's PA behavior include child care, active commuting to and from school, school recess, school physical education, after-school programs, churches, medical settings, and the home environment. Recommendations for practitioners and researchers are discussed.

    2013-07-01

    Most health care professionals involved in the management of people with haemophilia (PWH) believe that exercise is beneficial and its practice is widely encouraged. This article aims to demonstrate that appropriate exercise (adapted to the special needs of the individual PWH) may be beneficial for all PWH through improved physical, psychosocial and medical status. Based on evidence gathered from the literature, many PWH, particularly those using long-term prophylaxis or exhibiting a mild/moderate bleeding phenotype, are as active as their healthy peers. PWH experience the same benefits of exercise as the general population, being physically healthier than if sedentary and enjoying a higher quality of life (QoL) through social inclusion and higher self-esteem. PWH can also gain physically from increased muscle strength, joint health, balance and flexibility achieved through physiotherapy, physical activity, exercise and sport. Conversely, very little data exist on activity levels of PWH in countries with limited resources. However, regarding specific exercise recommendations in PWH, there is a lack of randomized clinical trials, and consequently formal, evidence-based guidelines have not been produced. Based on published evidence from this review of the literature, together with the clinical experience of the authors, a series of recommendations for the safe participation of PWH in regular physical activities, exercises and sport are now proposed. In summary, we believe that appropriately modified programmes can potentially allow all PWH to experience the physical and psychosocial benefits of being physically active which may ultimately lead to an improved QoL.

    Full Text Available Larry E Miller,1 William G Herbert1,2 1Miller Scientific Consulting, Inc., Asheville, NC, 2Department of Human Nutrition, Foods & Exercise, Virginia Tech, Blacksburg, VA, USA Abstract: Spinal cord injury (SCI is a traumatic, life-disrupting event with an annual incidence of 17,000 cases in the US. SCI is characterized by progressive physical deconditioning due to limited mobility and lack of modalities to allow safe physical activity that may partially offset these deleterious physical changes. Approximately, 50% of patients with SCI report no leisure-time physical activity and 15% report leisure-time physical activity below the threshold where meaningful health benefits could be realized. Collectively, about 363,000 patients with SCI, or 65% of the entire spinal cord injured population in the US, engages in insufficient physical activity and represents a target population that could derive considerable health benefits from even modest physical activity levels. Currently, the annual direct costs related to SCI exceed US$45 billion in the US. Rehabilitation protocols and technologies aimed to improve functional mobility have potential to significantly reduce the risk of medical complications and cost associated with SCI. Patients who commence routine physical activity in the first post-injury year and experience typical motor function improvements would realize US$290,000 to US$435,000 in lifetime cost savings, primarily due to fewer hospitalizations and less reliance on assistive care. New assistive technologies that allow patients with SCI to safely engage in routine physical activity are desperately needed.

    In 1991 a manuscript describing an instrument for studying magnetized plasmas was published in this journal. The Large Plasma Device (LAPD) was upgraded in 2001 and has become a national user facility for the study of basic plasma physics. The upgrade as well as diagnostics introduced since then has significantly changed the capabilities of the device. All references to the machine still quote the original RSI paper, which at this time is not appropriate. In this work, the properties of the updated LAPD are presented. The strategy of the machine construction, the available diagnostics, the parameters available for experiments, as well as illustrations of several experiments are presented here.

    The aim of this study was to gain formative research insights that can be used to design social marketing campaigns. One thousand four hundred fifty-nine people participated in an online survey. Factor analysis was undertaken to establish perceived benefits and barriers, and indexes were created for barriers, benefits, and healthy living knowledge. Four attitude groups were formed and analysis of variance was undertaken to explore group differences. Consumers with high perceived barriers report less physical activity than consumers with low perceived barriers to exercise. The current study provides evidence to suggest that exchange theory can offer important insights to inform social marketing intervention planning.

    Plant diversity loss impairs ecosystem functioning, including important effects on soil. Most studies that have explored plant diversity effects belowground, however, have largely focused on biological processes. As such, our understanding of how plant diversity impacts the soil physical environment remains limited, despite the fundamental role soil physical structure plays in ensuring soil function and ecosystem service provision. Here, in both a glasshouse and a long-term field study, we show that high plant diversity in grassland systems increases soil aggregate stability, a vital structural property of soil, and that root traits play a major role in determining diversity effects. We also reveal that the presence of particular plant species within mixed communities affects an even wider range of soil physical processes, including hydrology and soil strength regimes. Our results indicate that alongside well-documented effects on ecosystem functioning, plant diversity and root traits also benefit essential soil physical properties.

    An alternative approach of an arts-based instruction for Basic Physics class has been developed through the implementation of video analysis of a Javanesse traditional dance: Bambangan Cakil. A particular movement of the dance -weapon throwing- was analyzed by employing the LoggerPro software package to exemplify projectile motion. The results of analysis indicated that the movement of the thrown weapon in Bambangan Cakil dance provides some helping explanations of several physics concepts of projectile motion: object's path, velocity, and acceleration, in a form of picture, graph and also table. Such kind of weapon path and velocity can be shown via a picture or graph, while such concepts of decreasing velocity in y direction (weapon moving downward and upward) due to acceleration g can be represented through the use of a table. It was concluded that in a Javanesse traditional dance there are many physics concepts which can be explored. The study recommends to bring the traditional dance into a science class which will enable students to get more understanding of both physics concepts and Indonesia cultural heritage.

    This qualitative study is designed to examine the benefits of physical activity involvement with members of the same ethnic group. For this study, Korean immigrants who were members of Korean physical activity clubs such as badminton and tennis were selected as participants. Using a constructive grounded theory methodology, three themes were identified as benefits of physical activity involvement: (1) the experience of psychological well-being, (2) the creation of a unique cultural world, and (3) the facilitation of physical activity involvement. The findings of this study suggest that Korean immigrant participants gained various social, cultural, and psychological benefits by engaging in activities with other Korean immigrants.

  16. Does Replacing Sodium Excreted in Sweat Attenuate the Health Benefits of Physical Activity?

    Science.gov (United States)

    Turner, Martin J; Avolio, Alberto P

    2016-08-01

    International guidelines suggest limiting sodium intake to 86-100 mmol/day, but average intake exceeds 150 mmol/day. Participants in physical activities are, however, advised to increase sodium intake before, during and after exercise to ensure euhydration, replace sodium lost in sweat, speed rehydration and maintain performance. A similar range of health benefits is attributable to exercise and to reduction in sodium intake, including reductions in blood pressure (BP) and the increase of BP with age, reduced risk of stroke and other cardiovascular diseases, and reduced risk of osteoporosis and dementia. Sweat typically contains 40-60 mmol/L of sodium, leading to approximately 20-90 mmol of sodium lost in one exercise session with sweat rates of 0.5-1.5 L/h. Reductions in sodium intake of 20-90 mmol/day have been associated with substantial health benefits. Homeostatic systems reduce sweat sodium as low as 3-10 mmol/L to prevent excessive sodium loss. "Salty sweaters" may be individuals with high sodium intake who perpetuate their "salty sweat" condition by continual replacement of sodium excreted in sweat. Studies of prolonged high intensity exercise in hot environments suggest that sodium supplementation is not necessary to prevent hyponatremia during exercise lasting up to 6 hr. We examine the novel hypothesis that sodium excreted in sweat during physical activity offsets a significant fraction of excess dietary sodium, and hence may contribute part of the health benefits of exercise. Replacing sodium lost in sweat during exercise may improve physical performance, but may attenuate the long-term health benefits of exercise.

  17. The benefits of completing homework for students with different aptitudes in an introductory physics course

    2013-01-01

    We examine the relationship between homework completion and exam performance for students having different physics aptitudes for five different semesters of an introductory electricity and magnetism course. In our analysis, we plot exam scores versus homework completion scores and calculate the slopes of the line fits and the Pearson correlations. On average, completing many homework problems correlated to better exam scores only for students with high physics aptitude. Low aptitude physics students had a negative correlation between exam performance and completing homework; the more homework problems they did, the worse their performance was on exams. One explanation for this effect is that the assigned homework problems placed an excessive cognitive load on low aptitude students. As a result, no learning or even negative learning might have taken place when low aptitude students attempted to do assigned homework. Another explanation is based on the fact that the negative benefit effects first appeared when ...

    Full Text Available Robert Stanton,1 Brenda Happell,1 Peter Reaburn2 1Institute for Health and Social Science Research, Centre for Mental Health Nursing Innovation and School of Nursing and Midwifery, Central Queensland University, Rockhampton, QLD, Australia; 2School of Medical and Applied Sciences, Central Queensland University, Rockhampton, QLD, Australia Abstract: There is a large body of literature which examines the mental health benefits of physical activity. In general, studies report an inverse, dose dependent relationship between leisure-time physical activity participation, and mental health outcomes. Studies also show a positive association between maximal aerobic capacity and general well-being. More recent studies have confirmed the positive effects of physical activity participation on cognition, including the treatment and prevention of dementia. The current exercise prescription suggested for the treatment of depression is similar to that recommended to the general population for the development and maintenance of cardiorespiratory fitness. There is also strong evidence from large population level studies that long term physical activity participation reduces the risk of future depressive illness. From the available evidence, it would appear that physical activity performed at a frequency, intensity, and duration which is substantially less than that required for the development and maintenance of cardiorespiratory and muscular fitness in the general population, may afford significant benefits in reducing the risk of future depressive illness. This may be particularly encouraging for people with prior depressive illness, or at high risk of future depressive illness, since this vulnerable population already faces significant barriers to physical activity participation over and above those encountered by the general population.

    Motor planning in older adults likely relies on the overengagement of the prefrontal cortex (PFC) and is associated with slowness of movement and responses. Does a physically active lifestyle counteract the overrecruitment of the PFC during action preparation? This study used high-resolution electroencephalography to measure the effect of physical exercise on the executive functions of the PFC preceding a visuomotor discriminative task. A total of 130 participants aged 15-86 were divided into two groups based on physical exercise participation. The response times and accuracy and the premotor activity of the PFC were separately correlated with age for the two groups. The data were first fit with a linear function and then a higher order polynomial function. We observed that after 35-40 years of age, physically active individuals have faster response times than their less active peers and showed no signs of PFC hyperactivity during motor planning. The present findings show that physical exercise could speed up the response of older people and reveal that also in middle-aged people, moderate-to-high levels of physical exercise benefits the planning/execution of a response and the executive functions mediated by the PFC, counteracting the neural overactivity often observed in the elderly adults.

    2013-08-01

    Comparing the atom to a `tiny solar system' is a common teaching analogy, and the extent to which learners saw the systems as analogous was investigated. English upper secondary students were asked parallel questions about the physical interactions between the components of a simple atomic system and a simple solar system to investigate how they understood the forces acting within the two systems. A sample of just over 100 across the 15-18 age range responded to a pencil-and-paper instrument that asked about four aspects of the two systems. It was found that for both systems, about four fifths of students expected forces to decrease with increasing distance; but that only a little over half expected there to be interactions between the minor constituents (electrons and planets). Most students failed to apply Newton's third law to either system. There was a considerable difference in the extent to which respondents were able to identify the type of force acting in the systems (nearly all for the solar system, but only a small proportion in the case of the atom). The findings are considered in terms of both the limitations of students' understanding of the basic physics and possible implications for the use of the teaching analogy.

    The role of self-generated zonal flows (ZF) in transport regulation in magnetic confinement devices via its shear is a potent concept and a physics issue. However, as the experimental evidence of its existence in tokamaks is meagre, a basic physics experimental study of ZF associated with ion temperature gradient (ITG) drift modes has been performed in the Columbia Linear Machine. The difficult problem of detection of ZF has been solved via a novel diagnostic using the paradigm of frequency modulation (FM) in radio transmission. Using this and discrete short time Fourier transform, we find a power spectrum peak at ITG ('carrier') frequency of {approx}120 kHz and FM sidebands at frequency of {approx}2 kHz, which is identified as a ZF. It has all the signatures of a ZF: a potential at near zero frequency and poloidal symmetry (m = 0), toroidal symmetry (k{sub ||} = 0) and radial variations only. The results roughly agree with theoretical estimates given here.

    The purpose of the present study was to evaluate the influence of a mixed exercise program, including Greek traditional dances and upper body training, in physical function, strength and psychological condition of breast cancer survivors. Twenty-seven women (N = 27), who had been diagnosed and surgically treated for breast cancer, volunteered to participate in this study. The experimental group consisted of 14 women with mean age 56.6 (4.2) years. They attended supervised Greek traditional dance courses and upper body training (1 h, 3 sessions/week) for 24 weeks. The control group consisted of 13 sedentary women with mean age 57.1 (4.1) years. Blood pressure, heart rate, physical function (6-min walking test), handgrip strength, arm volume and psychological condition (Life Satisfaction Inventory and Beck Depression Inventory) were evaluated before and after the exercise program. The results showed significant increases of 19.9% for physical function, 24.3% for right handgrip strength, 26.1% for left handgrip strength, 36.3% for life satisfaction and also a decrease of 35% for depressive symptoms in the experimental group after the training program. Significant reductions of 9% for left hand and 13.7% for right hand arm volume were also found in the experimental group. Consequently, aerobic exercise with Greek traditional dances and upper body training could be an alternative choice of physical activity for breast cancer survivors, thus promoting benefits in physical function, strength and psychological condition.

    Study of the Moon, of its spin-orbital characteristics and parameters of the lunar interior is one of the traditional fields of the Kazan astronomical school. However, despite the incredible successes in space investigations of the planets and of the Moon, in last years the interest to celestial mechanics, ephemerides astronomy and astrometry is significantly decreased, especially among the young scientists and students. Therefore, it is encouraging to see the work of the third-year student, which is devoted to the study of the physical libration of the Moon. This report presents the results of the first stage of the above study associated with the study of Cassini's laws in the rotation of the Moon and the visualization of these laws by means the programming language Visual Basic. The Earth moves on the Moon's orbit in selenocentric frame. Dynamic coordinate system is based on the principal axes of inertia of the Moon. The x-axis is directed along the largest principal axis of inertia A, the axis z is a dynamic pole of the Moon associated with the smallest principal axis of inertia C. According to the first Cassini’s law the lunar pole is inclined at a constant angle approximately equal to 1.5 degree. The ascending node of the orbit is coincides with descending node of the lunar equator (the second Cassini’s law) and, as a result, the ecliptic pole lies between the orbit pole and spin pole. Therefore the three vectors directed from the lunar centre of mass to orbit pole, ecliptic pole and spin pole form a single plane. The third Cassini’s law reflects the uniform rotation of the Moon synchronised with orbital motion of the Moon around the Earth (in the selenocentric frame the Earth moves around the Moon). It’s necessary a significant time to calculate the corresponding coordinates of points, which move synchronously on the orbit and on the equator. In any time t the Earth moves with the mean velocity n and forms the angle n*t in the orbit plane. At the

    This research presents data relating to polyvinyl chloride (PVC) modification by means of reactive oligomer and measures technological, physical and mechanical properties of the modified composites. Polyisocyanate (PIC) has been chosen as the modifying reactive oligomer. It has been shown that insertion of the oligomer has a double effect on PVC. Primarily, PIC produces a plasticizing effect on PVC and in particular leads to an increase in thermal stability and melt flow index at the stage of processing. In addition, the molded PVC composites possess higher strength properties and lower deformability when exposed to temperature because of chemical transformations of PIC in polymer matrix and, as the result, the formation of cross-linked systems takes place. In this case, semi-interpenetrating structures are formed based on cross-linked products of PIC chemical transformations homogeneously distributed in the PVC matrix. It has been determined by means of IR-spectroscopy that the basic products of PIC curing are compounds with urea and biuret groups which leads to modifying effect on PVC especially: increase in strength, thermal and mechanical properties, and chemical resistance.

    2006-01-17

    Background: The predicted health benefits of becomingphysically active or fit will be exaggerated if health outcomes causefitness and activity rather than the converse in prospective andcross-sectional epidemiological studies. Objective: Assess whether therelationships of adiposity to fitness and activity are explained byadiposity prior to exercising. Design: Cross-sectional study of physicalfitness (running speed during 10km foot race) and physical activity(weekly running distance) to current BMI (BMIcurrent) and BMI at thestart of running (BMIstarting) in 44,370 male and 25,252 femaleparticipants of the National Runners' Health Study. Results: BMIstartingexplained all of the association between fitness and BMIcurrent in bothsexes, but less than a third of the association between physical activityand BMIcurrent in men. In women, BMIstarting accounted for 58 percent ofthe association between BMIcurrent and activity levels. The 95thpercentile of BMIcurrent showed substantially greater declines withfitness and activity levels than the 5th percentile of BMIcurrent in men(i.e., the negative slope for 95th percentile was 2.6-fold greater thanthe 5th percentile for fitness and 3-fold greater for activity) and women(6-fold and 3.4-fold greater, respectively). At all percentiles, theregression slopes relating BMIstarting to fitness were comparable orgreater (more negative) than the slopes relating BMIcurrent to fitness,whereas the converse was true for activity. Conclusion: Self-selectionbias accounts for all of the association between fitness and adiposityand probably a portion of other health outcomes, but has less affect onassociations involving physical activity

    Full Text Available Insidious declines in normal aging are well established. Emerging evidence suggests that non-pharmacological interventions, specifically cognitive and physical training, may counter diminishing age-related cognitive and brain functions. This randomized trial compared effects of two training protocols: cognitive training (CT versus physical training (PT on cognition and brain function in adults 56–75 years. Sedentary participants (N=36 were randomized to either CT or PT group for 3 hours/week over 12 weeks. They were assessed at baseline, mid-training and post-training using neurocognitive, MRI and physiological measures. The CT group improved on executive function whereas PT group’s memory was enhanced. Uniquely deploying cerebral blood flow (CBF and cerebral vascular reactivity (CVR MRI, the CT cohort showed increased CBF within the prefrontal and middle/posterior cingulate cortex without change to CVR compared to PT group. Improvements in complex abstraction were positively associated with increased resting CBF in dorsal anterior cingulate cortex. Exercisers with higher CBF in hippocampi bilaterally showed better immediate memory. The preliminary evidence indicates that increased cognitive and physical activity improves brain health in distinct ways. Reasoning training enhanced frontal networks shown to be integral to top-down cognitive control and brain resilience. Evidence of increased resting CBF without changes to CVR implicates increased neural health rather than improved vascular response. Exercise did not improve cerebrovascular response, although CBF increased in hippocampi of those with memory gains. Distinct benefits incentivize testing effectiveness of combined protocols to strengthen brain health.

    Full Text Available Physical Education teachers have been using some very classic team sports, like football, basketball, handball, volleyball, etc. for many years in order to develop their education work at school. As a consequence of this, the benefits of this kind of activities on Physical Education lessons have not been as notable as we mighthave expected, since, even if they are increasing, their development and application are still low. There are many and very varied new non-traditional sports that have emerged and extended across Spain in recent years. To mention an example, we could refer to a newly created non-traditional sport such as kin-ball. This sport wascreated for the purpose of achieving a way to combine several factors such as health, team-work and competitiveness. Three teams of four players each participate. This way, every player can participate to a great extent in all the moves of the match, for each of them must defend one area of their half in order to achieve a common objective. Besides, kin-ball helps to develop motor skills at school in an easy way; that is, coordination, balance and perception. There is a large variety of non-traditional games and sports that are similar to kin-ball, such as floorball, intercrosse, mazaball, tchoukball, ultimate, indiaca, shuttleball... All of them show many physical, psychic and social advantages, and can help us to make the Physical Education teaching-learning process more motivating, acquiring the recreational component that it showed some years ago and which hasnow disappeared

    Full Text Available One of very important prerequisites for achieving good results in races, in addition to genetic predisposition, quality training and good health, are optimal values for number of erythrocytes, concentration of haemoglobin and hematocrit, of which depends efficient oxygen supply of muscles during great efforts. The stated values, along with data on heart rate, are useful indicators of the degree of horse fitness and readiness for horse race. The influence of physical exertion on the values of basic hematological parameters as well as on heart rate, was investigated on 6 trotters, in training at the Belgrade racetrack (one head of Italian trotter, male, 3 years old; 3 heads of American trotter, male, 3,4 and 6 years old and two heads of Serbian trotter, female, 4 and 5 years old. The blood samples for hematological tests were taken by punction of jugular vein in resting phase - immediately before the commencement of work, after light trot warming for 3000 m and fast trot for 1000 m, with 30 minutes rest between the two runnings. The heart rate was monitored continuously by radio telemetry cardiometer, from the moment they were taken from their boxes and harnessing to the completion of work. The obtained results confirm the relationship between the rise of heart rate and hematocrit values: maximal hematocrit values were determined after the first running (0.49±0.05, in regard to 0.42±0.03 in resting phase, but 30 minutes after the second running there was a slight drop of hematocrit values (0.46±0.04. The blood samples in both cases were taken after fast trot during which there were recorded maximal pulse values, so in the moment of sampling the pulse lowered close to the values in resting - after the first running from 192.23±19.66, and after the second from 180.33±17.22 to 40.67±5.76.

    With an ever-increasing urban population, promoting public health and well-being in towns and cities is a major challenge. Previous research has suggested that participating in allotment gardening delivers a wide range of health benefits. However, evidence from quantitative analyses is still scarce. Here, we quantify the effects, if any, of participating in allotment gardening on physical, psychological and social health. A questionnaire survey of 332 people was performed in Tokyo, Japan. We compared five self-reported health outcomes between allotment gardeners and non-gardener controls: perceived general health, subjective health complaints, body mass index (BMI), mental health and social cohesion. Accounting for socio-demographic and lifestyle variables, regression models revealed that allotment gardeners, compared to non-gardeners, reported better perceived general health, subjective health complaints, mental health and social cohesion. BMI did not differ between gardeners and non-gardeners. Neither frequency nor duration of gardening significantly influenced reported health outcomes. Our results highlight that regular gardening on allotment sites is associated with improved physical, psychological and social health. With the recent escalation in the prevalence of chronic diseases, and associated healthcare costs, this study has a major implication for policy, as it suggests that urban allotments have great potential for preventative healthcare.

    Physical education (PE) programs are evolving from a traditional skill-centered model to a health-centered model that focuses on time engaged in moderate to vigorous physical activity (MVPA). However, improvements in muscular fitness and fundamental movement skills are prerequisites for continuous participation in MVPA. The purpose of this study was to examine the effects of integrative strength and skill-based training on measures of physical fitness in children during primary school PE. Children from two fourth grade PE classes were cluster randomized into either a fundamental integrative training (FIT) group (n = 20) or a control (CON) group (n = 21). The 8-week FIT program was performed twice per week during the first ∼ 1 5 minutes of each PE class and consisted of a circuit of strength and skill-based exercises. All participants were assessed for health- and skill-related fitness before and after the intervention. The outcome variables were analyzed via 2 × 2 repeated measures analysis of variance with post hoc analysis. A significant (p ≤ 0.05) interaction of group by time was observed in FIT participants with improvements in aerobic capacity, push-ups, sit and reach flexibility, and single-leg hop. There were no groups by time effects for the sit-up and long jump tests. No injuries were reported. These findings highlight the potential benefits of integrating both health- and skill-related fitness components into primary school PE as evidenced by improvements in measures of aerobic capacity and muscular fitness in children.

    The majority of "responders" to first-line cognitive-behavioural therapy (CBT) and pharmacological treatments for obsessive-compulsive disorder (OCD) are left with residual symptoms that are clinically relevant and disabling. Therefore, there is pressing need for widely accessible efficacious alternative and/or adjunctive treatments for OCD. Accumulating evidence suggests that physical exercise may be one such intervention in the mood and anxiety disorders broadly, although we are aware of only two positive small-scale pilot studies that have tested its clinical benefits in OCD. This pilot study aimed to test the feasibility and preliminary efficacy of adding a structured physical exercise programme to CBT for OCD. A standard CBT group was delivered concurrently with a 12-week customized exercise programme to 11 participants. The exercise regimen was individualized for each participant based on peak heart rate measured using an incremental maximal exercise test. Reports of exercise adherence across the 12-week regimen exceeded 80%. A paired-samples t-test indicated very large treatment effects in Yale-Brown Obsessive-Compulsive Scale scores from pre- to post-treatment in CBT group cohorts led by expert CBT OCD specialists (d = 2.55) and junior CBT clinician non-OCD specialists (d = 2.12). These treatment effects are very large and exceed effects typically observed with individual and group-based CBT for OCD based on leading meta-analytic reviews, as well as previously obtained treatment effects for CBT using the same recruitment protocol without exercise. As such, this pilot work demonstrates the feasibility and significant potential clinical utility of a 12-week aerobic exercise programme delivered in conjunction with CBT for OCD.

    This research applied self-determination theory to examine the degree to which satisfaction of basic psychological needs for autonomy, relatedness, and competence explained the association between socioeconomic status and physical and mental health outcomes, while controlling for age, exercise, and smoking status. This was a survey research study with 513 full-time employees in professions representative of a hierarchal organization. The results of the structural equation model verify that psychological need satisfaction mediates the inverse association between socioeconomic status and physical and mental health. Self-determination theory contributes to understanding the psychosocial roots of the uneven distribution of health across the socioeconomic gradient.

    Full Text Available Abstract Background The purpose was to: 1 perform a systematic review of studies examining the relation between physical activity, fitness, and health in school-aged children and youth, and 2 make recommendations based on the findings. Methods The systematic review was limited to 7 health indicators: high blood cholesterol, high blood pressure, the metabolic syndrome, obesity, low bone density, depression, and injuries. Literature searches were conducted using predefined keywords in 6 key databases. A total of 11,088 potential papers were identified. The abstracts and full-text articles of potentially relevant papers were screened to determine eligibility. Data was abstracted for 113 outcomes from the 86 eligible papers. The evidence was graded for each health outcome using established criteria based on the quantity and quality of studies and strength of effect. The volume, intensity, and type of physical activity were considered. Results Physical activity was associated with numerous health benefits. The dose-response relations observed in observational studies indicate that the more physical activity, the greater the health benefit. Results from experimental studies indicate that even modest amounts of physical activity can have health benefits in high-risk youngsters (e.g., obese. To achieve substantive health benefits, the physical activity should be of at least a moderate intensity. Vigorous intensity activities may provide even greater benefit. Aerobic-based activities had the greatest health benefit, other than for bone health, in which case high-impact weight bearing activities were required. Conclusion The following recommendations were made: 1 Children and youth 5-17 years of age should accumulate an average of at least 60 minutes per day and up to several hours of at least moderate intensity physical activity. Some of the health benefits can be achieved through an average of 30 minutes per day. [Level 2, Grade A]. 2 More vigorous

    This project was designed to test the feasibility of introducing ultrasound to senior medical students as a primary diagnostic tool in the evaluation of patients. Specifically, its aim was to determine if it is possible for medical students untrained in sonography to gain basic competence in performing abdominal ultrasound with limited didactic and hands-on instructions. Registered sonographers provided the students with hands-on instructions on the use of a compact ultrasound system. They were likewise shown how to evaluate specific organs and perform measurements. The results of the student measurements and those obtained by the sonographers were compared. There was close correlation between the results obtained by sonographers and students on both normal and abnormal findings. This supports the concept that medical students can be taught basic ultrasound skills with limited didactic and hands-on instructions with the potential of using these skills in the patient clinics as an adjunct to routine physical diagnosis.

    A pure {sup 7}Be beam with an energy E = 1-8 MeV is available for nuclear and applied physics at the 3 MV Pelletron tandem accelerator CIRCE in Caserta. The beam is produced using an offline technique. Typical analyzed beam intensities are about 2 ppA, using cathodes with an activity of the order of 200 MBq. The {sup 7}Be implantation has been used for both fundamental nuclear physics and applied physics. In particular, different metals have been implanted with {sup 7}Be in order to study the influence of the chemical composition and of the number of quasi-free electrons of the host material on the {sup 7}Be half-life. In the field of applied physics, the {sup 7}Be implantation turns out to be very interesting for wear measurement. In fact, in this case {sup 7}Be is used as a depth-sensitive tracer. The continuous detection of the sample activity during the wear allows a high sensitivity measurement of wearing speed. The {sup 7}Be beam production at CIRCE, the implantation procedure and the results obtained from the {sup 7}Be half-life measurements and the wear characterization of implanted steel samples are described.

    The professional activity that the cardiovascular surgeon performs is much more than a simple gesture to mechanically operate the patient's heart. There is in every act of intraoperative most notions of physiology and physics than we generally realize. This paper discusses, in the light of mathematics, on the dynamics of fluids, ie blood, focused on invasive measurements of blood pressure, the effect of vessel size on its internal resistance and the flow passing through it in conversion of various units of measurements of pressure and resistance, blood viscosity and its relationship to the vessel, hemodilution, differences in laminar and turbulent flow, velocity and blood pressure and wall tension after a stenosis and the origin of poststenotic aneurysm. This study is not to enable the reader to the knowledge of all physics, but to show it as a useful tool in explaining phenomena known in the routine of cardiovascular surgery.

  3. The expansion of a plasma into a vacuum - Basic phenomena and processes and applications to space plasma physics

    Science.gov (United States)

    Wright, K. H., Jr.; Stone, N. H.; Samir, U.

    1983-01-01

    In this review attention is called to basic phenomena and physical processes involved in the expansion of a plasma into a vacuum, or the expansion of a plasma into a more tenuous plasma, in particular the fact that upon the expansion, ions are accelerated and reach energies well above their thermal energy. Also, in the process of the expansion a rarefaction wave propagates into the ambient plasma, an ion front moves into the expansion volume, and discontinuities in plasma parameters occur. The physical processes which cause the above phenomena are discussed, and their possible application is suggested for the case of the distribution of ions and electrons (hence plasma potential and electric fields) in the wake region behind artificial and natural obstacles moving supersonically in a rarefied space plasma. To illustrate this, some in situ results are reexamined. Directions for future work in this area via the utilization of the Space Shuttle and laboratory work are also mentioned.

In both cases, violations of special relativity modifying cosmic-ray propagation or acceleration at very high energy can potentially play a role. Other violations of fundamental principles of standard particle physics (quantum mechanics, energy and momentum conservation, vacuum homogeneity and “static” properties, effective space dimensions, quark confinement… can also be relevant at these energies. In particular, UHECR data would in principle allow to set bounds on Lorentz symmetry violation (LSV in patterns incorporating a privileged local reference frame (the “vacuum rest frame”, VRF. But the precise analysis is far from trivial, and other effects can also be present. The effective parameters can be related to Planckscale physics, or even to physics beyond Planck scale, as well as to the dynamics and effective symmetries of LSV for nucleons, quarks, leptons and the photon. LSV can also be at the origin of GZK-like effects. In the presence of a VRF, and contrary to a “grand unification” view, LSV and other violations of standard principles can modify the internal structure of particles at very high energy and conventional symmetries may cease to be valid at energies close to the Planck scale. We present an updated discussion of these topics, including experimental prospects, new potentialities for high-energy cosmic ray phenomenology and the possible link with unconventional pre-Big Bang scenarios, superbradyon (superluminal preon patterns… The subject of a possible superluminal propagation of neutrinos at accelerator energies is also dealt with.

    The purpose of hot wire anemometry is to measure the speed of an air stream. The classical method is based on the measure of the value of a temperature dependant resistor inserted in a Wheatstone bridge (Lomas 1986 Fundamentals of Hot Wire Anemometry (Cambridge: Cambridge University Press)). In this paper we exhibit the physics behind this method and show that by using a wire whose resistance does not vary on the field of temperature explored (from 20 °C to 200 °C), it is however possible to make accurate measurements. Finally, limitations of the method are discussed.

    Full Text Available This article sets out to conduct a systematic review of the current literature on active video games as potential educational tools for physical education or physical activity. To begin with, research on active video games for educational and physical purposes has been examined with the purpose of verifying improvement of attitudes, intellectual skills, knowledge, motor skills and physical properties associated with physical activity and physical education. A second aim will be to determine the effectiveness of active video games compared with traditional approaches to physical activity. From this perspective, a systematic literature search from relevant international databases was conducted from January to July 2015 in order to find papers published in journals or conference proceedings from January 2010 onwards. Then, 2648 references were identified in database searches and 100 of these papers met the inclusion criteria. Two main conclusions are to be drawn from this research. Firstly, controlled studies demonstrate that active video games increase capacities in relation to physical activity and education. Secondly, Research also shows that physical activity interventions designed and measured using behavioural theories are more likely to be successful in comparison with traditional exercise activities.

    The purpose of this work is to share our findings in using video gaming technology to facilitate the understanding of basic electromagnetism with pre-service elementary teachers. To this end we explored the impact of using a game called Supercharged! on pre-service teachers' understanding of electromagnetic concepts compared to students who conducted a more traditional inquiry oriented investigation of the same concepts. This study was a part of a larger design experiment examining the pedagogical potential of Supercharged! the control group learned through a series of guided inquiry methods while the experimental group played Supercharged! during the laboratory sections of the science course. There was significant difference F(2,134) = 4.8, p positive learning outcomes, as demonstrated by the increase in test scores from pre- to post-assessment. Additionally, this study also suggests that a complementary approach, in which video games and hands-on activities are integrated, with each activity informing the other, could be a very powerful technique for supporting student scientific understanding. Further, our findings suggest that video game designers should embed meta-cognitive activities such as reflective opportunities into educational video games to provide scaffolds for students and to reinforce that they are engaged in an educational learning experience.

  8. New Ideas for the Extra Dimensions and for Deriving the Basic Laws of Physics

    Full Text Available As geometry is constructed from points and their separating distances, physics may be similarly constructed using identical material points and their separating distances with the additional requirement that all points have infinitesimal masses and move all the time at the speed of light. Pairs of such points can get locked together in circles to make doublet particles that can have any speed from zero to that of light, at which point the doublet disintegrates. Using this construct together with the rich mathematical properties of a 3D space, a mechanical definition of time, and simple symmetry rule for displacement, it is possible to derive many of the fundamental laws of physics such as the inverse square laws of gravitation and static electricity, many of the relativistic and quantum mechanical results such as the mass-energy conversion of Einstein and the quantized energy levels of Planck and Bohr. In addition, a better understanding of some illusive terms like inertia and force becomes possible. No arbitrary constants are needed in the process. Extra dimensions (variables that are not a distance are created as a result of this setup --- but they are all found to be discrete. Mass, charge, spin, and time are some notable examples.

    Surveyed adolescents at single-sex high schools to examine whether perceptions of physical activity differed by gender. The most helpful cue to physical activity for males and females was having a friend to exercise with. Parental encouragement and having a parent who exercised were also helpful. Wanting to do other things was a common barrier to…

  13. Basic microscopic plasma physics unified and simplified by N-body classical mechanics

    Escande, Dominique; Elskens, Yves

    2012-01-01

    Debye shielding, collisional transport, Landau damping of Langmuir waves, and spontaneous emission of these waves are introduced, in typical plasma physics textbooks, in different chapters. This paper provides a compact unified introduction to these phenomena without appealing to fluid or kinetic models, but by using Newton's second law for a system of $N$ electrons in a periodic box with a neutralizing ionic background. A rigorous equation is derived for the electrostatic potential. Its linearization and a first smoothing reveal this potential to be the sum of the shielded Coulomb potentials of the individual particles. Smoothing this sum yields the classical Vlasovian expression including initial conditions in Landau contour calculations of Langmuir wave growth or damping. The theory is extended to accommodate a correct description of trapping or chaos due to Langmuir waves. In the linear regime, the amplitude of such a wave is found to be ruled by Landau growth or damping and by spontaneous emission. Using...

    The first direct gravitational-wave detection was made by the Advanced Laser Interferometer Gravitational Wave Observatory on September 14, 2015. The GW150914 signal was strong enough to be apparent, without using any waveform model, in the filtered detector strain data. Here those features of the signal visible in these data are used, along with only such concepts from Newtonian and General Relativity as are accessible to anyone with a general physics background. The simple analysis presented here is consistent with the fully general-relativistic analyses published elsewhere, in showing that the signal was produced by the inspiral and subsequent merger of two black holes. The black holes were each of approximately 35 Msun, still orbited each other as close as 350 km apart and subsequently merged to form a single black hole. Similar reasoning, directly from the data, is used to roughly estimate how far these black holes were from the Earth, and the energy that they radiated in gravitational waves.

    Our previous study shows that the curvature of the plasma meniscus causes the beam halo in the negative ion sources: the negative ions extracted from the periphery of the meniscus are over-focused in the extractor due to the electrostatic lens effect, and consequently become the beam halo. In this article, the detail physics of the plasma meniscus and beam halo formation is investigated with two-dimensional particle-in-cell simulation. It is shown that the basic physical parameters such as the H{sup −} extraction voltage and the effective electron confinement time significantly affect the formation of the plasma meniscus and the resultant beam halo since the penetration of electric field for negative ion extraction depends on these physical parameters. Especially, the electron confinement time depends on the characteristic time of electron escape along the magnetic field as well as the characteristic time of electron diffusion across the magnetic field. The plasma meniscus penetrates deeply into the source plasma region when the effective electron confinement time is short. In this case, the curvature of the plasma meniscus becomes large, and consequently the fraction of the beam halo increases.

    Rheumatoid arthritis (RA) is an autoimmune disease, which not only affects the joints but can also impact on general well-being and risk for cardiovascular disease. Regular physical activity and exercise in patients with RA have numerous health benefits. Nevertheless, the majority of patients with RA are physically inactive. This indicates that people with RA might experience additional or more severe barriers to physical activity or exercise than the general population. This narrative review provides an overview of perceived barriers, benefits and facilitators of physical activity and exercise in RA. Databases were searched for articles published until September 2014 using the terms 'rheumatoid arthritis', 'physical activity', 'exercise', 'barriers', 'facilitators', 'benefits', 'motivation', 'motivators' and 'enablers'. Similarities were found between disease-specific barriers and benefits of physical activity and exercise, e.g. pain and fatigue are frequently mentioned as barriers, but reductions in pain and fatigue are perceived benefits of physical activity and exercise. Even though exercise does not influence the existence of barriers, physically active patients appear to be more capable of overcoming them. Therefore, exercise programmes should enhance self-efficacy for exercise in order to achieve long-term physical activity and exercise behaviour. Encouragement from health professionals and friends/family are facilitators for physical activity and exercise. There is a need for interventions that support RA patients in overcoming barriers to physical activity and exercise and help sustain this important health behaviour.

    Ultrasonography (US) has been used in medical imaging for over half a century. Current US scanners are based largely on the same basic principles used in the initial devices for human imaging. Modern equipment uses a pulse-echo approach with a brightness-mode (B-mode) display. Fundamental aspects of the B-mode imaging process include basic ultrasound physics, interactions of ultrasound with tissue, ultrasound pulse formation, scanning the ultrasound beam, and echo detection and signal processing. Recent technical innovations that have been developed to improve the performance of modern US equipment include the following: tissue harmonic imaging, spatial compound imaging, extended field of view imaging, coded pulse excitation, electronic section focusing, three-dimensional and four-dimensional imaging, and the general trend toward equipment miniaturization. US is a relatively inexpensive, portable, safe, and real-time modality, all of which make it one of the most widely used imaging modalities in medicine. Although B-mode US is sometimes referred to as a mature technology, this modality continues to experience a significant evolution in capability with even more exciting developments on the horizon.

    The Cross-Section Evaluation Working Group (CSEWG) is a long-standing committee charged with responsibility for organizing and overseeing the US cross-section evaluation effort. It`s main product is the official US evaluated nuclear data file, ENDF. In 1992 CSEWG added the Measurements Committee to its list of standing committees and subcommittees. This action was based on a recognition of the importance of experimental data in the evaluation process as well as the realization that measurement activities in the US were declining at an alarming rate and needed considerable encouragement to avoid the loss of this resource. The mission of the Committee is to maintain contact with experimentalists in the Us and to encourage them to contribute to the national nuclear data effort. Improved communication and the facilitation of collaborative activities are among the tools employed in achieving this objective. In 1994 the Committee was given an additional mission, namely, to serve as an interface between the applied interests represented in CSEWG and the basic nuclear science community. Accordingly, its name was changed to the Measurement and Basic Physics Committee. The present annual report is the third such document issued by the Committee. It contains voluntary contributions from several laboratories in the US. Their contributions were submitted to the Chairman for compilation and editing.

    Physical activity is known to improve emotional experiences, and positive emotions have been shown to lead to important life outcomes, including the development of psychosocial resources. In contrast, time spent sedentary may negatively impact emotional experiences and, consequently, erode psychosocial resources. Two studies tested whether activity independently influenced emotions and psychosocial resources, and whether activity indirectly influenced psychosocial resources through emotional experiences. Using cross-sectional (Study 1a) and longitudinal (Study 1b) methods, we found that time spent physically active independently predicted emotions and psychosocial resources. Mediation analyses suggested that emotions may account for the relation between activity and psychosocial resources. The improved emotional experiences associated with physical activity may help individuals build psychosocial resources known to improve mental health. Study 1a provided first indicators to suggest that, in contrast, sedentary behaviour may reduce positive emotions, which could in turn lead to decrements in psychosocial resources.

    Full Text Available Large and consistent beneficial effects with few adverse effects have been found in relation to physical exercise in selected samples of elderly subjects. However, thus far, it has not been confirmed to what extent the effects of physical exercise among elderly people are beneficial or even harmful in population-based studies. Additionally, the role of exercise testing among elderly people remains unclear. Firstly, the effects of prolonged physical training on cardiovascular fitness in 66-85-year-old women were examined in a cross-sectional study. Secondly, the predictive value of exercise-test status and results, including exercise capacity for survival, were studied in 75-year-old men and women. Thirdly, the effects of an endurance and strength training programme were examined in women aged 76 to 78 years in a population-based randomized controlled trial. Finally, the cardiac-adverse effects of acute exercise in the form of a cycle ergometer test were clarified in 75-year-old men and women. In the maximal exercise tests the mean peak oxygen uptake was respectively 26.2 and 18.7 ml·kg-1·min-1 among the physically active and less active control women. High cycling power (Watts per kg body weight in the completed ergometer test was associated with decreased risk for death (multivariate HR 0.20; CI 0.08 - 0.50. The 18-week strength training resulted in a 9.4% increase in peak oxygen uptake while the endurance training improved peak oxygen uptake by 6.8%. A significant increase in cycling power in W/kg was found in the strength and endurance training groups compared to controls. Five cases of cardio- or cerebrovascular health problems emerged in the exercise training groups. These health problems were not directly related to physical exertion. In the final study 23 and 7% of the exercise tests in men and women, respectively, were prematurely terminated because of cardiac arrhythmia or ST segment depressions.

    Full Text Available Abstract Osteoarthritis prevalence is increasing, placing greater demands on healthcare and future socioeconomic costing models. Exercise and non-pharmacological methods should be employed to manage this common and disabling disease. Expectations at all stages of disease are increasing with a desire to remain active and independent. Three key areas have been reviewed; the evidence for physical activity, lifestyle changes and motivational techniques concerning knee osteoarthritis and the barriers to instituting such changes. Promotion of activity in primary care is discussed and evidence for compliance has been reviewed. This article reviews a subject that is integral to all professionals involved with osteoarthritis care.

    Lung cancer continues to be a difficult disease frequently diagnosed in late stages with a high mortality and symptom burden. In part because of frequent lung comorbidity, even lung cancer survivors often remain symptomatic and functionally limited. Though targeted therapy continues to increase treatment options for advanced-stage disease, symptom burden remains high with few therapeutic options. In the last several decades, exercise and physical activity have arisen as therapeutic options for obstructive lung disease and lung cancer. To date, exercise has been shown to reduce symptoms, increase exercise tolerance, improve quality of life, and potentially reduce length of stay and postoperative complications. Multiple small trials have been performed in perioperative non-small-cell lung cancer patients, although fewer studies are available for patients with advanced-stage disease. Despite the increased interest in this subject over the last few years, a validated exercise regimen has not been established for perioperative or advanced-stage disease. Clinicians underutilize exercise and pulmonary rehabilitation as a therapy, in part because of the lack of evidence-based consensus as to how and when to implement increasing physical activity. This review summarizes the existing evidence on exercise in lung cancer patients.

    Full Text Available We examined the independent association between moderate-to-vigorous physical activity (MVPA and insulin resistance (IR among obese Latino children (N=113; 7–15 years who were enrolled in a community-based obesity intervention. Baseline information on physical activity was gathered by self-report. Clinical assessments of body composition, resting energy expenditure (REE, as well as glucose and insulin responses to an oral glucose tolerance test (OGTT were performed after an overnight fast. Insulin resistance was defined as a 2 h insulin concentration >57 μU·mL-1. We observed that those obese children who met the 2008 Guidelines for MVPA (≥60 min/day experienced a significantly lower odds of IR compared with those not meeting the Guidelines (OR=0.29; 95% CI: (0.10–0.92 and these findings were independent of age, sex, pubertal stage, acculturation, fasting insulin, and 2 h glucose concentrations. Efforts to promote 60 min or more of daily MVPA among children from ethnic minority and high-risk communities should assume primary public health importance.

    Parkinson's is a neurodegenerative disease commonly associated with symptoms such as tremor, rigidity, bradykinesia, freezing during gait, motor control deficits and instability. These physical symptoms can cause a myriad of psychological problems including depression, feelings of loneliness, and low self-esteem. Current research suggests pharmacological interventions do not sufficiently address all symptoms and thus alternative therapies have been deemed an important part of treatment for people with Parkinson's. Dance has shown to be a beneficial activity for this population. Upon reviewing recent dance for Parkinson's studies it is clear that there are developing trends with respect to overall approach. The tendency to place more emphasis on changes to clinical signs is creating a gap whereby research neglects to look at how dance is influencing a particular individual in all aspects of their life. There is a need for a framework that allows for and encourages the analysis of the dancing experience for people with Parkinson's on a variety of levels including physically, mentally, emotionally, and socially. With such a framework it would be possible to triangulate the information gathered to draw stronger conclusions that are more meaningful to the people with Parkinson's. This paper would like to propose the use of the World Health Organization's International Classification of Functioning, Disability, and Health as a possible framework for dance for Parkinson's research.

    Background: Traditional Chinese sports and physical activities (PAs) have a long history and are practiced by millions of Chinese. However, relatively few systematic reviews of the scientific evidence for their health benefits, especially for older Chinese adults, have been undertaken. Evidence acquisition: Between January and March 2016, a systematic search was conducted using the CNKI and PubMed databases to identify studies published between 2000 and 2015. Studies were selected for review if they were designed specifically to evaluate the health benefits of traditional Chinese sports and PAs in adults aged 50 years and older in the Mainland of China. The studies included observational, uncontrolled, and randomized and controlled designs. Papers published without an English title or abstract were excluded. Evidence synthesis: The initial search identified a total of 229 studies. After removing duplicates and studies that did not meet the inclusion/exclusion criteria, 95 studies were selected for review. Special attention was given to studies of the most commonly practiced activities:Tai Ji Quan, Qigong, and Yangko exercises. A positive association between these types of exercise and health benefits was noted for healthy older adults and those with chronic diseases. Evidence on other types of activities was less clear due to the limited number of studies conducted. Conclusion: There is promising evidence that traditional Chinese sports and PAs provide many health benefits for older Chinese adults. While additional scientifically rigorous research is warranted, promoting these traditional and culturally-based sports and PAs as forms of behavioral medicine in primary and secondary prevention of diseases among the aging Chinese population will help fulfill an urgent public health need.

  12. Autonomy supportive environments and mastery as basic factors to motivate physical activity in children: a controlled laboratory study

    Full Text Available Abstract Background Choice promotes the experience of autonomy, which enhances intrinsic motivation. Providing a greater choice of traditional active toys may increase children's activity time. Mastery also increases intrinsic motivation and is designed into exergames, which may increase play time of a single exergame, reducing the need for choice to motivate activity compared to traditional active toys. Providing both choice and mastery could be most efficacious at increasing activity time. The energy expenditure (EE of an active play session is dependent on the duration of play and the rate of EE during play. The rate of EE of exergames and the same game played in traditional fashion is not known. The purpose was to test the basic parameters of choice and mastery on children's physical activity time, activity intensity, and energy expenditure. Methods 44 children were assigned to low (1 toy or high (3 toys choice groups. Children completed 60 min sessions with access to traditional active toys on one visit and exergame versions of the same active toys on another visit. Results Choice had a greater effect on increasing girls' (146% than boys' (23% activity time and on girls' (230% than boys' (minus 24% activity intensity. When provided choice, girls' activity time and intensity were no longer lower than boys' activity time and intensity. The combination of choice and mastery by providing access to 3 exergames produced greater increases in physical activity time (1 toy 22.5 min, 3 toys 41.4 min than choice alone via access to 3 traditional games (1 toy 13.6 min, 3 toys 19.5 min. Energy expenditure was 83% greater when engaging in traditional games than exergames. Conclusions Boys and girls differ in their behavioral responses to autonomy supportive environments. By providing girls with greater autonomy they can be motivated to engage in physical activity equal to boys. An environment that provides both autonomy and mastery is most efficacious at

    Several treatments have been developed aiming the prevention of bone loss. There are discussions about the best prophylactic and therapeutic procedures for osteoporosis. This study evaluated the effects of physical exercise associated with risedronate as a prophylactic and therapeutic procedure in osteopenic bones of rats submitted to ovariectomy. We used 48 Wistar rats divided into: ovariectomized or subjected to sham surgery. Ovariectomized rats were divided into the following sub-groups: OVX, 12 weeks sedentary; OVX-EX, treadmill training for 12 weeks; OVX-RA, 12 weeks with risedronate administration; and OVX-EX-RA, 12 weeks with risedronate administration and treadmill training. Rats subjected to sham surgery were divided into the following sub-groups: SH, 12 weeks sedentary; SH-EX, treadmill training for 12 weeks; SH-RA, 12 weeks with risedronate administration; and SH-EX-RA, 12 weeks with risedronate administration and training on the treadmill. The effectiveness of the treatment was evaluated in tibias using biomechanical, radiological, histomorphometric, and immunohistochemical analyses. Data were analyzed by statistical tests, with significance level of P bones of ovariectomized rats.

    The emergence of social media platforms in the consumer space unlocked new ways of interaction between individuals on the Web. People develop now their social networks and relations based on common interests and activities with the choice to opt-in or opt-out on content of their interest. This kind of platforms have also an important place to fill inside large organizations and enterprises where communication and collaborators interaction are keys for development. Enterprise Social Networking Systems (ESN) add value to an organization by encouraging information sharing, capturing knowledge, enabling action and empowering people. CERN is currently rolling out an ESN which aims to unify and provide a single point of access to the multitude of information sources in the organization. It also implements social features that can be added on top of existing communication channels. While the deployment of this kind of platforms is not without risks we firmly believe that they are of the best interest for our community, opening the opportunity to evaluate a global social network for High Energy Physics (HEP).

  15. All basic condensed matter physics phenomena and notions mirror in biology – A hypothesis, two examples and a novel prediction

    Indian Academy of Sciences (India)

    2002-02-01

    A few billion years of evolutionary time and the complex process of ‘selection’ has given biology an opportunity to explore a variety of condensed matter phenomena and situations, some of which have been discovered by humans in the laboratory, that too only in extreme non-biological conditions such as low temperatures, high purity, high pressure etc., in the last centuries. Biology, at some level, is a complex and self-regulated condensed matter system compared to the ‘inanimate’ condensed matter systems such as liquid 4He, liquid water or a piece of graphite. In this article I propose a hypothesis that ‘all basic condensed matter physics phenomena and notions (already known and ones yet to be discovered) mirror in biology’. I explain this hypothesis by considering the idea of ‘Bose condensation’ or ‘momentum space order’ and discuss two known example of quantum magnetism encountered in biology. I also provide some new and rather speculative possibility, from light harvesting in biological photosynthesis, of mesoscopic exciton condensation related phenomena at room temperature.

    In this critical narrative review, we examine the role of physical activity (PA), recreational and elite sports in the development of knee/hip osteoarthritis (OA), taking into account the role of injury in this relationship. The process of article selection was unsystematic. Articles were selected on the basis of the authors' expertise, self-knowledge, and reflective practice. In the general adult population, self-reported diagnosis of knee/hip OA was not associated with low, moderate or high levels of PA. For studies using radiographic knee/hip OA as a primary outcome, the incidence of asymptomatic radiographic OA was higher for subjects with the highest quartile of usual PA than the least active subjects. The risk of incident radiographic knee/hip OA features was increased for subjects with a history of regular sports participation (for osteophyte formation but not joint space narrowing). This risk depended on the type of sport (team and power sports but not endurance and running), and certain conditions (high level of practice) were closely related to the risk of injury. The prevalence of radiographic OA was significantly higher, especially the presence of osteophytes, in former elite athletes than controls. The risk of OA was higher with participation in mixed sports, especially soccer or power sports, than endurance sport. However, the prevalence of clinical OA between former elite athletes and controls was similar, with less hip/knee disability in former athletes. Moderate daily recreational or sport activities, whatever the type of sport, are not a consistent risk factor for clinical or radiographic knee/hip OA. Risk of injury in different sports may be the key factor to understanding the risk of OA related to sport.

    Full Text Available Abstract Background In a majority of cases, whiplash injuries are a domain of conservative therapy. Nevertheless it remains unclear whether physical therapy is of medical or economic benefit in patients with whiplash injuries. Methods Seventy patients with acute Quebec Task Force (QTF grade II whiplash injuries were randomized to two therapy groups and received either active (APT or passive (PPT physical therapy. Patients were compared with regard to pain and range of motion with data obtained in an earlier study from a group with grade II whiplash injuries in which the therapy recommendation had been "act as usual" (AAU; n = 20. The above-mentioned parameters were assessed at 24 hours and two months after the injury. Furthermore patients' period of disability was documented after two months. Results After two months, patients in both the APT and PPT groups showed significant improvement in the median period of disability (active: 14 days; passive: 14 days compared to the AAU group (49 days. No group difference was observed with regard to median improvement in range of motion (active: 120°; passive: 108°; activity as usual: 70°. The median pain reduction was significantly greater in the APT group (50.5 than in the PPT (39.2 or AAU group (28.8. Conclusion Our data show that active physical therapy results in enhanced pain reduction and shortening of post-injury disability. Therefore, active physical therapy should be considered the treatment of choice in patients with QTF grade II whiplash injuries. Trial registration The study complied with applicable German law and with the principles of the Helsinki Declaration and was approved by the institutional ethics commission.

    The CPT project came to an end in December 2006 and its original scope is now shared among three new areas, namely Computing, Offline and Physics. In the physics area the basic change with respect to the previous system (where the PRS groups were charged with detector and physics object reconstruction and physics analysis) was the split of the detector PRS groups (the old ECAL-egamma, HCAL-jetMET, Tracker-btau and Muons) into two groups each: a Detector Performance Group (DPG) and a Physics Object Group.

    Full Text Available Background: Hearing, a strong line of communication that enables individuals to learn about the world around them, is a major factor contributing to the psychomotor development of every individual. Hearing loss can also affect the conception and perception of sounds and rhythm. Objective: The purpose of this study was to describe and analyse the benefits of Square and Round dancing for persons with hearing loss. Methods: The present study is an analytic-descriptive qualitative research. The sample was constituted non-probabilistically based on the following features: a a participant had to have hearing problems (hearing loss and b had to have participated regularly in Square dance for at least two years. Each participant was asked to name possible people to be interviewed (snowball technique. We analysed the data of 7 individuals (6 males and 1 female with hearing loss. The mean age of the dancers with hearing loss was 51.3 years. The participants had no cochlear implants or any other physical or vision related impairments. Results: The present findings constitute the first published survey regarding Czech Square dancers' status, their family's hearing status, hearing aid use, communication preference, education in integrated or segregated settings, the influence of family background on dance initiation, coach preference (hearing or deaf, and the environment for participation in Square dance as a mode of physical activity with regular dancers and with dancers with hearing loss as well. In the present sample of dancers with hearing loss, most were from hearing families and had hearing siblings. The degree to which individuals with hearing loss feel comfortable with the hearing world appears to influence their later preference for participating in regular, as opposed to segregated, physical activities. More than half of the dancers with hearing loss who participated in this research study would like to meet with the deaf minority. One of the

    It would seem that the present dry economic times impose a very precise focus for science in general and physics in particular: research, possibly of applied type. However in doing so two basic pillars of a healthy future for science are being undermined: fundamental research and public engagement. The first is what makes applications possible in the first place, many times with a path from inception to implementation that is as long and indirect as poorly advertised. The second pillar, public engagement, is mostly regarded as a commodity: if there is good level of funding scientists can consider spending money for public relations otherwise this is the first thing scientists cut because it is the least necessary. On the contrary, public engagement in science is very much needed, at the very least because the public is either an enemy or an ally, as testified respectively by the climate change denial and the 2009 Shuttle mission that people wanted in order to service the Hubble Space Telescope for the last ti...

    [Purpose] This study was to investigate the impacts of senior brain heath exercise (SBHE) program for 12 weeks to basic active physical fitness, cognitive function and brain derived neurotrophic factor (BDNF) in elderly women. [Methods] Subject of this study is total of 24 women in the age of 65-79 who can conduct normal daily activity and communication but have not participated in regular exercise in recent 6 months. The study groups were divided into an exercise group (EG, n=13) and a control group (CG, n=11). The exercise program was consisted of SBHE, and training frequency was 4 times weekly, of which training time was a total of 50 minutes each time in level of intensity of 9-14 by rating of perceived exertion (RPE). [Results] First, 12-week SBHE program has shown statistical increase in basic physical fitness in the EG comparing with the CG, such as lower body strength, upper body strength and aerobic endurance, but not in flexibility, agility and dynamic balance. Second, in the case of Mini-mental state examination Korean version (MMSE-K) and BDNF, it showed that there was a statistically significant increase in the EG comparing with the CG. [Conclusion] In this study, 12-week SBHE program has resulted in positive effect on change of basic physical fitness (strength and aerobic endurance), cognitive function and BDNF. If above program adds movements that can enhance flexibility, dynamic balance and agility, this can be practical exercise program to help seniors maintain overall healthy lifestyle. PMID:27508149

  13. Magnetic nanoparticle heating and heat transfer on a microscale: Basic principles, realities and physical limitations of hyperthermia for tumour therapy.

    Science.gov (United States)

    Dutz, Silvio; Hergt, Rudolf

    2013-12-01

    In this review article we present basic principles of magnetically induced heat generation of magnetic nanoparticles for application in magnetic particle hyperthermia. After explanation of heating mechanisms, the role of particle-particle as well as particle-tissue interactions is discussed with respect to achievable heating power of the particles inside the tumour. On the basis of heat transfer theory at the micro-scale, the balance between generated and dissipated heat inside the tumour and the resulting damaging effects for biological tissue is examined. The heating behaviour as a function of tumour size is examined in combination with feasible field strength and frequency. Numerical calculations and experimental investigations are used to show the lower tumour size limit for tumour heating to therapeutically suitable temperatures. In summary, this article illuminates practical aspects, limitations, and the state of the art for the application of magnetic heating in magnetic particle hyperthermia as thermal treatment of small tumours.

  14. Stone crayfish in the Czech Republic: how does its population density depend on basic chemical and physical properties of water?

    Directory of Open Access Journals (Sweden)

    Vlach P.

    2013-03-01

    Full Text Available The stone crayfish (Austropotamobius torrentium Schrank is one of the two native crayfish species in the Czech Republic. The populations as well as physical and chemical parameters of water (pH, conductivity, dissolved oxygen, undissolved particles, NH3, NH4+, NO2−, NO3−, phosphorus, Ca2+ and SO42 −  of 33 streams were examined to find the ecological plasticity of this crayfish and some relations between these parameters and population densities. The mentioned parameters often significantly varied at the sites. Two approaches were applied to find relations between these parameters and observed abundance. At first, the observed streams were compared using RDA (streams  ×  physical-chemical parameters. No significance was found while testing relationship between the streams grouped along the 1st axis of model and the observed abundances of stone crayfish. However, some correlations between abundance and conductivity, calcium, nitrates and sulphates were found using polynomial regression. These relationships are explicable in terms of mutual correlations, underlying geology and other factors which affect abundances. In conclusion, A. torrentium is able to inhabit waters with a large range of physical and chemical parameters of the water without any fundamental influence on population densities. Water properties play an indisputable role as limiting ecological factors at uncommon concentrations, but population densities are probably influenced much more by the types of habitats, habitat features, predation and other ecological factors.

    Dementia cases are on the rise and researchers seek innovative ways to prevent or ameliorate cognitive impairment in later life. Some research has reported that combining mental and physical exercise may benefit cognition more than either alone. This randomized pilot trial examined the feasibility and cognitive benefit for older adults (n = 30) of a single bout of neuro-exergaming (physical activity with cognitive training) using an interactive physical and cognitive exercise system (iPACES), compared with that of exergaming or neurogaming alone. Intent-to-treat and sensitivity analyses were conducted using repeated-measures ANOVA, controlling for age, sex, and education. A significant interaction effect was found for executive function (Color Trails 2), with a significant improvement in the neuro-exergaming condition. Results demonstrate feasibility for older adults to use a novel and theoretically-derived neuro-exergame, and also provide promising new evidence that neuro-exergaming can yield greater cognitive benefit than either of its component parts.

  16. High-energy cosmic rays and tests of basic principles of Physics. Looking at the Planck scale and beyond

    Gonzalez-Mestres, L.

    2014-04-01

    With the present understanding of data, the observed flux suppression for ultra-high energy cosmic rays (UHECR) at energies above 4.1019 eV can be a signature of the Greisen-Zatsepin-Kuzmin (GZK) cutoff or be related to a similar mechanism. But it may also correspond, for instance, to the maximum energies available at the relevant sources. In both cases, violations of special relativity modifying cosmic-ray propagation or acceleration at very high energy can potentially play a role. Other violations of fundamental principles of standard particle physics (quantum mechanics, energy and momentum conservation, vacuum homogeneity and "static" properties, effective space dimensions, quark confinement…) can also be relevant at these energies. In particular, UHECR data would in principle allow to set bounds on Lorentz symmetry violation (LSV) in patterns incorporating a privileged local reference frame (the "vacuum rest frame", VRF). But the precise analysis is far from trivial, and other effects can also be present. The effective parameters can be related to Planckscale physics, or even to physics beyond Planck scale, as well as to the dynamics and effective symmetries of LSV for nucleons, quarks, leptons and the photon. LSV can also be at the origin of GZK-like effects. In the presence of a VRF, and contrary to a "grand unification" view, LSV and other violations of standard principles can modify the internal structure of particles at very high energy and conventional symmetries may cease to be valid at energies close to the Planck scale. We present an updated discussion of these topics, including experimental prospects, new potentialities for high-energy cosmic ray phenomenology and the possible link with unconventional pre-Big Bang scenarios, superbradyon (superluminal preon) patterns… The subject of a possible superluminal propagation of neutrinos at accelerator energies is also dealt with.

    Evidence-based recommendations for physical activity following spinal fusion surgeries for idiopathic scoliosis are limited, specifically in the adolescent population. Individuals with scoliosis treated operatively or non-operatively have been reported to participate in less than 1–3 days/week of even mildly strenuous physical exercises. Over 40% of individuals with scoliosis returned to sports at a level lower than pre-operative participation levels or did not return at all post spinal fusion. It is particularly important for human movement specialists, such as physical therapists, occupational therapists, athletic trainers and kinesiologists to assist these individuals effectively transition to and maintain engagement in physical activity. This review provides a snapshot of common considerations and potential factors influencing individuals with spinal-fusion for scoliosis to participate in safe physical activity.

    2011-07-01

    The aim of this study was to examine differences in traditional heart rate variability measurements and heart rate complexity (sample entropy) in young adults grouped by objectively measured achievement of either moderate or both moderate and vigorous physical activity recommendations. Of 168 young adults tested (86 females, 82 males; age 20.5 ± 1.2 years), 119 achieved only recommendations for moderate physical activity (moderate group) and 49 achieved recommendations for both moderate and vigorous physical activity (vigorous group). Analysis of covariance controlling for sex, weekly minutes of moderate physical activity, and percentage of body fat was used to assess between-group differences in heart rate variability and heart rate complexity. Logistic regression analysis was used to determine the group characteristics that best predicted high heart rate complexity and vagal indices of heart rate variability. The majority of the autonomic measures were higher (P heart rate complexity and higher heart rate variability. Young adults engaged in regular vigorous physical activity were more than twice as likely to have high heart rate complexity than those involved in predominantly moderate exercise. These findings suggest that vigorous physical activity is more closely associated with high heart rate complexity than moderate physical activity in young adults.

    The Cross-Section Evaluation Working Group (CSEWG) is a long-standing committee charged with the responsibility for organizing and overseeing the U.S. cross-section evaluation effort. It`s main product is the official U.S. evaluated nuclear data file, ENDF. The current version of this file is Version VI. All evaluations included in ENDF are reviewed and approved by CSEWG and issued by the U.S. Nuclear Data Center, Brookhaven National Laboratory. CSEWG is comprised of volunteers from the U.S. nuclear data community who possess expertise in evaluation methodologies and who collectively have been responsible for producing most of the evaluations included in ENDF. In 1992 CSEWG added the Measurements Committee to its list of standing committees and subcommittees. This action was based on a recognition of the importance of experimental data in the evaluation process as well as the realization that measurement activities in the U.S. were declining at an alarming rate and needed all possible encouragement to avoid the loss of this resource. The mission of the Committee is to maintain a network of experimentalists in the U.S. that would provide needed encouragement to the national nuclear data measurement effort through improved communication and facilitation of collaborative activities. In 1994, an additional charge was added to the responsibilities of this Committee, namely, to serve as an interface between the more applied interests represented in CSEWG and the basic nuclear science community. This annual report is the second such document issued by the Committee. It contains voluntary contributions from eleven laboratories in the U.S. which have been prepared by members of the Committee and submitted to the Chairman for compilation and editing. It is hoped that the information provided here on the work that is going on at the reporting laboratories will prove interesting and stimulating to the readers.

    2013-03-01

    This article examines the cultural and public health challenges associated with the dissemination of the Swedish approach and methods of physical education throughout France and illustrates the two main methods of influence, both direct through research and study visits and indirect through the creation of an international network entitled the International Federation of Physical Education. More particularly, it studies the roles of Philippe Tissié in 1898 and Pierre Seurin in 1946, and shows how these two major players of French physical education contributed actively to strengthening Swedish influence throughout France. It also highlights their equally essential role in the successful implementation of a pro-Swedish network in France, intended to serve their public health aims. This analysis forms part of the geopolitical and socio-cultural history of foreign physical education models, whose exemplarity was mainly dependent on Franco-Swedish relations and the models' social representations. Using archives from the French Physical Education League, travel logs and the Revue des jeux scolaires et d'hygiène sociale (Journal for School Games and Social Hygiene), it has been shown why the myth of the Swedish Eldorado contributed to creating, in France, "a work of art and of science that was, at the same time, both national and practical."

    A Sleeping Beauty in Science is a publication that goes unnoticed (sleeps) for a long time and then, almost suddenly, attracts a lot of attention (is awakened by a prince). In this paper we investigate important properties of Sleeping Beauties, particularly to find out to what extent Sleeping Beauties are application-oriented and thus are potential Sleeping Innovations. In this study we focus primarily on physics (including materials science and astrophysics) and present first results for chemistry and for engineering & computer science. We find that more than half of the SBs are application-oriented. Therefore, it is important to investigate the reasons for and processes related to delayed recognition. First we analyze basic properties of the SBs such as the time-dependent distribution, author characteristics (names of authors, country, institution), as well as the journals and fields of the SBs are analyzed. Next we develop a new approach in which the cognitive environment of the SBs is analyzed, based ...

    Theoretical quantifications of hydrogen bonding (HB) basicities and acidities, originally developed for aliphatic systems (J. Chem. Inf. Comput. Sci. 2004, 44, 1042-1055), are now extended to cover aromatic, heterocyclic, anionic, cationic and zwitter-ionic molecular fragments, thus encompassing a majority of druggable chemical space. The addition of terms accounting for cavity formation, polarity, hydrophobicity, and resonance allowed us to derive a new equation able to predict accurately free energies of solvation of diverse solutes, interphase transfers, and aqueous solubilities (log S(w)). We thus provide a "universal solvation equation" (USE) available for the accurate estimation of desolvation energies in protein-ligand docking, for the prediction of many physical and ADMET properties, and for studying fluid phase equilibria.

    There is general consensus that physical activity is important for preserving functional capacities of older adults and positively influencing quality of life. While accelerometry is widely accepted and applied to assess physical activity in studies, several problems with this method remain (e.g., low retest reliability, measurement errors). The aim of this study was to test the intra-instrumental retest reliability of a wrist-worn accelerometer in a 3-day measurement of physical activity in older adults and to compare different estimators. A sample of 123 older adults (76.5 ± 5.1 years, 59 % female) wore a uniaxial accelerometer continuously for 1 week. The data were split into two repeated measurement values (week set) of 3 days each. The sum, the 80-99th quantiles and the 80-99th trimmed sums were built for each week set. Retest reliability was assessed for each estimator and graphically demonstrated by Bland-Altman plots. The intraclass correlation of the retest reliability ranged from 0.22 to 0.91. Retest reliability increases when a more robust estimator than the overall sum is used. Therefore, the trimmed sum can be recommended as a conservative estimate of the physical activity level of older adults.

    PICALM, BIN1, CLU, and APOE are top candidate genes for Alzheimer's disease, and they influence episodic memory performance in old age. Physical activity, however, has been shown to protect against age-related decline and counteract genetic influences on cognition. The aims of this study were to assess whether (a) a genetic risk constellation of PICALM, BIN1, and CLU polymorphisms influences cognitive performance in old age; and (b) if physical activity moderates this effect. Data from the SNAC-K population-based study were used, including 2,480 individuals (age range = 60 to 100 years) free of dementia at baseline and at 3- to 6-year follow-ups. Tasks assessing episodic memory, perceptual speed, knowledge, and verbal fluency were administered. Physical activity was measured using self-reports. Individuals who had engaged in frequent health- or fitness-enhancing activities within the past year were compared with those who were inactive. Genetic risk scores were computed based on an integration of risk alleles for PICALM (rs3851179 G allele, rs541458 T allele), BIN1 (rs744373 G allele), and CLU (rs11136000 T allele). High genetic risk was associated with reduced episodic memory performance, controlling for age, education, vascular risk factors, chronic diseases, activities of daily living, and APOE gene status. Critically, physical activity attenuated the effects of genetic risk on episodic memory. Our findings suggest that participants with high genetic risk who maintain a physically active lifestyle show selective benefits in episodic memory performance.

    Law-based governance is an important method to ensure a sound and sustainable mechanism of fund raising and benefit adjusting in basic medical insurance system. At the legislative level, the fund raising principles should be confirmed; a scientific and socialized mechanism for benefit adjusting should be achieved by law-based approaches; and the interest factors and market factors should be embodied in medical insurance payment mechanism. At the law enforcement level, the public law process should be intensified in the phase of fund-raising;the principle of power separation and restriction must be reflected in the horizontal division of functions and powers, while the powers of health care system design and decision-making should be concentrated to a upper level in the vertical division of functions and powers; and administrative responsibilities must be defined at various law-enforcement agencies.%法治是健全稳定可持续的基本医保筹资机制和待遇调整机制的重要手段。我国未来要在立法层面上明确医保的筹资原则,并通过法治途径实现待遇调整机制的科学化和社会化,医保付费机制的法律制度设计要体现利益因素和市场因素;在执法层面上应当在筹资阶段注重公法程序的强化,横向职权划分要体现分权制衡原则,纵向职权划分要把医保制度设计权和决策权集中上收,并明确各级执法机构的行政责任。

    To be able to obtain a rational understanding of the soil behavior, it is necessary to perform a rheologically-oriented investigation of the basic index and mineralogical characteristics of the soils found in nature. On the other hand, to determine the quantitative physical properties it is also important to have a knowledge of the governing physical laws and the application of these laws to the soil behavior. Finally, it is of utmost significance to have a proper assessment of the parameters that govern the soils which in turn have to be adjusted to their behavior in the field through the understanding of the stratigraphy, their observation and their analysis in the laboratory. [Spanish] Para el conocimiento racional del comportamiento de los suelos, es necesaria la investigacion reologica de las caracteristicas indice y mineralogica basica de los suelos que se representan en la naturaleza. Asi tambien, para conocer la propiedad cuantitativa fisica se hace necesario el conocimiento de las leyes fisicas que lo gobiernan y la aplicacion en su comportamiento. Ademas, tiene gran importancia la correcta investigacion de los parametros que los rigen y que deben adecuarse al comportamiento de los suelos en campo, por medio del conocimiento estratigrafico, la observacion y el analisis en el laboratorio.

    This study systematically reviewed the impact of physical exercise interventions on physical fitness for individuals with Down syndrome. Articles published in English were searched from five major electronic databases, namely, CINAHL, Medline, PsychINFO, SPORTDiscus, and PEDro from inception until April 2013. These studies were screened through predefined inclusion and exclusion criteria. Data were then extracted and synthesized from the studies included. Meta-analyses were carried out where appropriate. Ten studies fulfilled the inclusion criteria. Of the 10 studies, five studies were found to have high quality research methodology according to the PEDro scale. Varying exercise programs were used and four different fitness outcomes were evaluated: (i) balance, (ii) muscle strength and endurance, (iii) cardiovascular fitness, and (iv) body composition. Exercise interventions led to moderate to high effects on improving muscular strength and balance ((Equation is included in full-text article.)=0.74-1.10) whereas other outcomes showed less conclusive or limited positive evidence. Trends in the results suggest that exercise interventions improve muscular strength and balance. Suggestions for future research include follow-ups to the intervention to examine the longitudinal effects of exercise as well as controlling for confounding factors such as participants' compliance rate and severity levels of Down syndrome to enhance the effectiveness of the interventions.

    An x-ray tube mainly emits low-energy X-rays, with few maximum energy E₀ (equal in keV to the voltage U in kV) x-rays. Aluminium filtration (mandatory minimum thickness of 1.5 to 2.5 mm based on tube voltage) reduces soft X-rays and provides a mean energy equal to 2/3 E₀. The half value layer of a reference material characterizes the spectrum. X-ray attenuation in tissues is due to secondary electron interactions: photoelectric effect at low-energy, especially in dense materials with high Z number; compton effect at intermediate-energy, proportional to density. The optimization of acquisition parameters of a medically necessary examination is based on appropriate selection of the highest voltage (U in kV) providing the best contrast and lowest tube current (Q in mAs) providing a diagnostic image.

    The coating of capillary inner surface is considered to be an effective approach to suppress the adsorption of proteins on capillary inner surface in CE. However, most of coating materials reported are water-soluble, which may dissolve in BGE during the procedure of electrophoresis. In this study, a novel strategy for selection of physically coating materials has been illustrated to get coating layer with excellent stability using materials having poor solubility in commonly used solvents. Taking natural chitin as example (not hydrolyzed water soluble chitosan), a simple one step coating method using chitin solution in hexafluoroisopropanol was adopted within only 21 min with good coating reproducibility (RSDs of EOF for within-batch coated capillaries of 1.55% and between-batch coated capillaries of 2.31%), and a separation of four basic proteins on a chitin coated capillary was performed to evaluate the coating efficacy. Using chitin coating, the adsorption of proteins on capillary inner surface was successfully suppressed with reversed and stable EOF, and four basic proteins including lysozyme, cytochrome c, ribonuclease A and α-chymotrypsinogen A were baseline separated within 16 min with satisfied separation efficiency using 20 mM pH 2.0 H3PO4-Na2HPO4 as back ground electrolyte and 20 kV as separation voltage. What is more important, the chitin coating layer could be stable for more than two months during this study, which demonstrates that chitin is an ideal material for preparing semi-permanent coating on bare fused silica capillary inner wall and has hopeful potential in routine separation of proteins with CE.

    Full Text Available Introduction and objectives: The population aging represents a serious health problem. A physical exercise program will be beneficial for elderly people with associated illnesses. The objective of this study was the development of a physical exercise program in order to benefit the cardiovascular function. Method: A descriptive, prospective study was carried out with 20 patients (men and women equally over 60 years of age in Cifuentes municipality. Results: The average age was 68.9 years. There was a prevalence of arterial hypertension, chronic ischemic heart disease, heart failure, hypercholesterolemia, diabetes mellitus and musculoskeletal diseases. Twenty percent of the patients were considered as frail elderly people. There were no significant differences concerning the consumption of medications according to the sex, however there was a significant reduction of the consumption of medications in females at the end of the study – from 8.3 to 6.6 daily (x² =14,1 p < 0,05. The exercise program used had a very significant statistical result on the physical and psychic wellbeing of the patients (x² =24,1, p < 0,01; and a total of 16 elderly people (80 %, x²=15.4, p < 0,05, achieved a control of the arterial tension and the cardiac rhythm. It reduced the rate-pressure product and the myocardial oxygen consumption. Conclusions: The implementation of a physical exercise program, under the supervision of trained personnel, contributes to control the arterial tension and the cardiac rhythm, and favors an optimal cardiac output. It also has a very positive effect on the physical and psychic wellbeing of this group of patients because it improves their self-esteem and their desire to live.

    It is often said that the major stumbling block for doing scientific outreach is money because of funding issues. Ignoring that the true issue is the lack of time and/or inclination on the part of practicing scientists, this statement is too generic to be quantitative or even complete: in fact, as for every project or investment, the discussion should be based on context and impact. Initiatives are at hand to do outreach that cost nothing more than the budget already in place for a University, its Departments and its scientific research groups: it is more a matter of capitalizing existing assets at a University in a concerted way and taking full advantage of these assets by means of synergetic collaborations. I will describe one such collaboration among the School of Dance and the Astronomy and Physics Departments at the University of Maryland: the dance performance ``Gravity,'' inspired by gravitational-wave astronomy. Similar types of partnerships represent new promising ways of doing science communications according to what can be rightly called a marketing strategy (http://arxiv.org.abs/1210.0082).

    The long-term benefits of habitual physical activity during adolescence on adult bone structure and strength are poorly understood. We investigated whether physically active adolescents had greater bone size, density, content, and estimated bone strength in young adulthood when compared to their peers who were inactive during adolescence. Peripheral quantitative computed tomography (pQCT) was used to measure the tibia and radius of 122 (73 females) participants (age mean ± SD, 29.3 ± 2.3 years) of the Saskatchewan Pediatric Bone Mineral Accrual Study (PBMAS). Total bone area (ToA), cortical density (CoD), cortical area (CoA), cortical content (CoC), and estimated bone strength in torsion (SSIp ) and muscle area (MuA) were measured at the diaphyses (66% tibia and 65% radius). Total density (ToD), trabecular density (TrD), trabecular content (TrC), and estimated bone strength in compression (BSIc ) were measured at the distal ends (4%). Participants were grouped by their adolescent physical activity (PA) levels (inactive, average, and active) based on mean PA Z-scores obtained from serial questionnaire assessments completed during adolescence. We compared adult bone outcomes across adolescent PA groups in each sex using analysis of covariance followed by post hoc pairwise comparisons with Bonferroni adjustments. When adjusted for adult height, MuA, and PA, adult males who were more physically active than their peers in adolescence had 13% greater adjusted torsional bone strength (SSIp , p adolescence had 10% larger adjusted CoA (p adolescence seemed to persist into young adulthood, with greater ToA and SSIp in males, and greater CoA, CoC, and TrC in females.

    There have been three physics meetings since the last CMS week: “physics days” on March 27-29, the Physics/ Trigger week on April 23-27 and the most recent physics days on May 22-24. The main purpose of the March physics days was to finalize the list of “2007 analyses”, i.e. the few topics that the physics groups will concentrate on for the rest of this calendar year. The idea is to carry out a full physics exercise, with CMSSW, for select physics channels which test key features of the physics objects, or represent potential “day 1” physics topics that need to be addressed in advance. The list of these analyses was indeed completed and presented in the plenary meetings. As always, a significant amount of time was also spent in reviewing the status of the physics objects (reconstruction) as well as their usage in the High-Level Trigger (HLT).

    This descriptive comparative study examined differences in personal characteristics, exercise self-efficacy, benefits and barriers of independent elderly women to perform physical activity (PA) according with the PA level. Two hundred three women older than 60 years of age, from a community located in Nuevo Leon, Mexico participated in the study. Data was collected using: a) A personal data questionnaire, b) Exercise Self-Efficacy Scale, c) Exercise Benefits/ Barriers Scale and d) Physical Activity Scale for the Elderly were completed. Age was similar in participants with low and acceptable PA level. Participants with lower levels of PA reported consuming more medications, fewer years of education and lower values of exercise self-efficacy, benefits and barriers. In this sample, exercise self-efficacy and benefits were positively associated with the PA level.

    A remarkable amount of progress has been made in Physics since the last CMS Week in June given the exponential growth in the delivered LHC luminosity. The first major milestone was the delivery of a variety of results to the ICHEP international conference held in Paris this July. For this conference, CMS prepared 15 Physics Analysis Summaries on physics objects and 22 Summaries on new and interesting physics measurements that exploited the luminosity recorded by the CMS detector. The challenge was incorporating the largest batch of luminosity that was delivered only days before the conference (300 nb-1 total). The physics covered from this initial running period spanned hadron production measurements, jet production and properties, electroweak vector boson production, and even glimpses of the top quark.

    1995-01-01

    Since the study of wavelets is a relatively new area, much of the research coming from mathematicians, most of the literature uses terminology, concepts and proofs that may, at times, be difficult and intimidating for the engineer. Wavelet Basics has therefore been written as an introductory book for scientists and engineers. The mathematical presentation has been kept simple, the concepts being presented in elaborate detail in a terminology that engineers will find familiar. Difficult ideas are illustrated with examples which will also aid in the development of an intuitive insight. Chapter 1 reviews the basics of signal transformation and discusses the concepts of duals and frames. Chapter 2 introduces the wavelet transform, contrasts it with the short-time Fourier transform and clarifies the names of the different types of wavelet transforms. Chapter 3 links multiresolution analysis, orthonormal wavelets and the design of digital filters. Chapter 4 gives a tour d'horizon of topics of current interest: wave...

    The all-plenary format of the CMS week in Cyprus gave the opportunity to the conveners of the physics groups to present the plans of each physics analysis group for tackling early physics analyses. The presentations were complete, so all are encouraged to browse through them on the Web. There is a wealth of information on what is going on, by whom and on what basis and priority. The CMS week was followed by two CMS “physics events”, the ICHEP08 days and the physics days in July. These were two weeks dedicated to either the approval of all the results that would be presented at ICHEP08, or to the review of all the other Monte-Carlo based analyses that were carried out in the context of our preparations for analysis with the early LHC data (the so-called “2008 analyses”).

    Since the last CMS Week, all physics groups have been extremely active on analyses based on the full 2010 dataset, with most aiming for a preliminary measurement in time for the winter conferences. Nearly 50 analyses were approved in a “marathon” of approval meetings during the first two weeks of March, and the total number of approved analyses reached 90. The diversity of topics is very broad, including precision QCD, Top, and electroweak measurements, the first observation of single Top production at the LHC, the first limits on Higgs production at the LHC including the di-tau final state, and comprehensive searches for new physics in a wide range of topologies (so far all with null results unfortunately).

    Full Text Available Many studies have addressed the benefits of physical activity in elderly people. However, the physical activity models followed have not always taken into account the role of active articipation. In general, these models have been mainly influenced by directive methodologies and emphasise physical training; these aspects offer greater group control and less organizational effort. The main aim of this study was to compare two physical activity programs for elderly people and determine their effect on mood, self- esteem, and enjoyment with physical activity. The study participants were 72 women between 55 years and 70 years (M = 64.10; DT = 9.40 from the municipalities of Arousa Norte (Galicia, Spain. The results show that the supervised exercise programs benefitted the participants’ psychological health, which differed according to the type of program. Thus, a unique physical exercise model cannot be endorsed in adulthood, because the role of the participants and the way they interact within exercise programs varies, leading to differing effects on health and therefore on everyday life. New multidimensional proposals should be developed that combine physical, mental, and social aspects within a movement-based approach.

    Emulsions are generally made out of two immiscible fluids like oil and water, one being dispersed in the second in the presence of surface-active compounds.They are used as intermediate or end products in a huge range of areas including the food, chemical, cosmetic, pharmaceutical, paint, and coating industries. Besides the broad domain of technological interest, emulsions are raising a variety of fundamental questions at the frontier between physics and chemistry. This book aims to give an overview of the most recent advances in emulsion science. The basic principles, covering aspects of emulsions from their preparation to their destruction, are presented in close relation to both the fundamental physics and the applications of these materials. The book is intended to help scientists and engineers in formulating new materials by giving them the basics of emulsion science.

    The collisions last year at 900 GeV and 2.36 TeV provided the long anticipated collider data to the CMS physics groups. Quite a lot has been accomplished in a very short time. Although the delivered luminosity was small, CMS was able to publish its first physics paper (with several more in preparation), and commence the commissioning of physics objects for future analyses. Many new performance results have been approved in advance of this CMS Week. One remarkable outcome has been the amazing agreement between out-of-the-box data with simulation at these low energies so early in the commissioning of the experiment. All of this is testament to the hard work and preparation conducted beforehand by many people in CMS.

Since December, the large data samples from CMSSW_2_1 were completed.

The pinnacle of our physics programme was an observation of a new particle – a strong candidate for a Higgs boson – which has captured worldwide interest and made a profound impact on the very field of particle physics. At the time of the discovery announcement on 4 July, 2012, prominent signals were observed in the high-resolution H→γγ and H→ZZ(4l) modes. Corroborating excess was observed in the H→W+W– mode as well. The fermionic channel analyses (H→bb, H→ττ), however, yielded less than the Standard Model (SM) expectation. Collectively, the five channels established the signal with a significance of five standard deviations. With the exception of the diphoton channel, these analyses have all been updated in the last months and several new channels have been added. With improved analyses and more than twice the i...

    ERT is an economic instrument which helps power companies achieve emission reduction compliance cost-effectively. This paper presents the basics of ERT with reference to trading concepts, types of systems and types of emissions. The paper also describes the state of the Canadian energy market regarding greenhouse gases (GHG), nitrogen oxides, sulphur dioxide and volatile organic compounds. The association between ERT and district energy is also explained. By 2010, the global market for GHG trading is expected to be worth $10 billion to $3 trillion U.S. Canada has committed to reducing its GHG to 6 per cent below 1990 levels by 2012, but currently emits 705 Mt per year. This is expected to increase to 770 Mt by 2010. Therefore, in order to meet its commitment, GHGs will have to be reduced 200 Mt per year. Canada is currently considering ratifying the Kyoto agreement and a trading system is being developed. There are several abatement technologies currently under consideration for district energy systems, including adding scrubbers, improving efficiency, and fuel switching. The marginal cost of abatement was also discussed. tabs., figs.

With these final LHC Run 1 datasets in hand, CMS Physics Analysis Groups have been busy analysing these data in preparation for the winter conferences. Moreover, despite the fact that the pp run only concluded in mid-December (and there was consequently less time to complete data analyses), CMS again made a strong showing at the Rencontres de Moriond in La Thuile (EW and QCD) where nearly 40 new results were presented. The highlight of these preliminary results was the eagerly anticipated updated studies of the properties of the Higgs boson discovered in July of last year.

    The Electroweak and Top Quark Workshop (16-17th of July) A Workshop on Electroweak and Top Quark Physics, dedicated on early measurements, took place on 16th-17th July. We had more than 40 presentations at the Workshop, which was an important milestone for 2007 physics analyses in the EWK and TOP areas. The Standard Model has been tested empirically by many previous experiments. Observables which are nowadays known with high precision will play a major role for data-based CMS calibrations. A typical example is the use of the Z to monitor electron and muon reconstruction in di-lepton inclusive samples. Another example is the use of the W mass as a constraint for di-jets in the kinematic fitting of top-quark events, providing information on the jet energy scale. The predictions of the Standard Model, for what concerns proton collisions at the LHC, are accurate to a level that the production of W/Z and top-quark events can be used as a powerful tool to commission our experiment.

    The main programme of the Physics Week held between 16th and 20th May was a series of topology-oriented workshops on di-leptons, di-photons, inclusive W, and all-hadronic final states. The goal of these workshops was to reach a common understanding for the set of objects (ID, cleaning...), the handling of pile-up, calibration, efficiency and purity determination, as well as to revisit critical common issues such as the trigger. Di-lepton workshop Most analysis groups use a di-lepton trigger or a combination of single and di-lepton triggers in 2011. Some groups need to collect leptons with as low PT as possible with strong isolation and identification requirements as for Higgs into WW at low mass, others with intermediate PT values as in Drell-Yan studies, or high PT as in the Exotica group. Electron and muon reconstruction, identification and isolation, was extensively described in the workshop. For electrons, VBTF selection cuts for low PT and HEEP cuts for high PT were discussed, as well as more complex d...

    All the first-year students in the University of Electro-Communications (UEC) take "Basic Physics I", "Basic Physics II" and "Physics Laboratory" as required subjects; Basic Physics I and Basic Physics II are calculus-based physics of mechanics, wave and oscillation, thermal physics and electromagnetics. Physics Laboratory is designed mainly aiming at learning the skill of basic experimental technique and technical writing. Although 95% students have taken physics in the senior high school, they poorly understand it by connecting with experience, and it is difficult to learn Physics Laboratory in the university. For this reason, we introduced two ICT (Information and Communication Technology) systems of Physics Laboratory to support students'learning and staff's teaching. By using quantitative data obtained from the ICT systems, we can easily check understanding of physics contents in students, and can improve physics education.

    Full Text Available Abstract Background This study aimed to systematically review the evidence from randomized controlled trials (RCTs and to conduct a meta-analysis of the effects of yoga on physical and psychosocial outcomes in cancer patients and survivors. Methods A systematic literature search in ten databases was conducted in November 2011. Studies were included if they had an RCT design, focused on cancer patients or survivors, included physical postures in the yoga program, compared yoga with a non-exercise or waitlist control group, and evaluated physical and/or psychosocial outcomes. Two researchers independently rated the quality of the included RCTs, and high quality was defined as >50% of the total possible score. Effect sizes (Cohen’s d were calculated for outcomes studied in more than three studies among patients with breast cancer using means and standard deviations of post-test scores of the intervention and control groups. Results Sixteen publications of 13 RCTs met the inclusion criteria, of which one included patients with lymphomas and the others focused on patients with breast cancer. The median quality score was 67% (range: 22–89%. The included studies evaluated 23 physical and 20 psychosocial outcomes. Of the outcomes studied in more than three studies among patients with breast cancer, we found large reductions in distress, anxiety, and depression (d = −0.69 to −0.75, moderate reductions in fatigue (d = −0.51, moderate increases in general quality of life, emotional function and social function (d = 0.33 to 0.49, and a small increase in functional well-being (d = 0.31. Effects on physical function and sleep were small and not significant. Conclusion Yoga appeared to be a feasible intervention and beneficial effects on several physical and psychosocial symptoms were reported. In patients with breast cancer, effect size on functional well-being was small, and they were moderate to large for psychosocial outcomes.

The American Heart Association, the Centers for Disease Control and Prevention and the American College of Sports Medicine all recommend regular physical activity of moderate intensity for the prevention and complementary treatment of several diseases. The therapeutic role of exercise in maintaining good health and treating diseases is not new. The benefits of physical activity date back to Susruta, a 600 BC physician in India, who prescribed exercise to patients. Hippocrates (460–377 BC wrote “in order to remain healthy, the entire day should be devoted exclusively to ways and means of increasing one's strength and staying healthy, and the best way to do so is through physical exercise.” Plato (427–347 BC referred to medicine as a sister art to physical exercise while the noted ancient Greek physician Galen (129–217 AD penned several essays on aerobic fitness and strengthening muscles.

We highlight an overlooked aspect in scholarly work: the role of stereotypes about...... beneficiaries of cross-border welfare. We present results from an original large-scale survey experiment (N=2525) among Swedish voters, randomizing exposure to cues about recipients' country of origin and family size. Consistent with a model emphasizing the role of stereotypes, respondents react to cues about...... recipient identity. These effects are strongest among respondents high in ethnic prejudice and economic conservatism. The findings imply that stereotypes about who benefits from cross-border welfare rights condition public support for those rights....

    2013-01-01

    There is no doubt that nanoscience will be the dominant direction for technology in this century, and that this science will influence our lives to a large extent as well as open completely new perspectives on all scientific and technological disciplines. To be able to produce optimal nanosystems with tailor-made properties, it is necessary to analyze and construct such systems in advance by adequate theoretical and computational methods. Since we work in nanoscience and nanotechnology at the ultimate level, we have to apply the basic laws of physics. What methods and tools are relevant here? The book gives an answer to this question. The background of the theoretical methods and tools is critically discussed, and also the world view on which these physical laws are based. Such a debate is not only of academic interest but is of highly general concern, and this is because we constantly move in nanoscience and nanotechnology between two extreme poles, between infinite life and total destruction . On the one ...

    针对超稠油油藏开展火烧油层技术可行性研究的需要,利用自行设计研制的火烧油层物理模拟实验装置,分别采用超稠油、特稠油、普通稠油开展了火烧油层燃烧基础参数物理模拟实验.对比了不同类型稠油门槛温度、燃料消耗量等燃烧基础参数,结合产出油组分及温度场发育特征,分析了超稠油燃烧基础参数特征.研究认为,超稠油油藏开展火烧油层试验是可行的,超稠油门槛温度、燃料消耗量等燃烧基础参数值均高于其他类型稠油;稠油火烧油层的驱油效率与黏度相关,黏度越大其燃料消耗量越大,其最终的驱油效率相对较低;火烧后原油性质发生了明显改善.%A physical simulation system has been designed and developed to study the feasibility of in - situ combustion for super heavy oil reservoirs. Physical simulation experiments have been carried out for the basic parameters of in - situ combustion by respectively using super heavy oil, extra heavy oil and conventional heavy oil. Basic combustion parameters such as threshold temperature and fuel consumption have been compared for different types of heavy oil. The parameter characteristics of super heavy oil combustion have been analyzed combining with produced oil composition and temperature field characteristics. It has been concluded that in - situ combustion is feasible for super heavy oil reservoirs, whose threshold temperature and fuel consumption are higher than other types of heavy oil. The displacement efficiency of in - situ combustion is related to oil viscosity. The higher the viscosity is, the bigger the fuel consumption is, and the lower the ultimate displacement efficiency will be. Crude oil properties have been substantially improved after in - situ combustion.

  7. OPERATOR-RELATED FORMULATION OF THE EIGENVALUE PROBLEM FOR THE BOUNDARY PROBLEM OF ANALYSIS OF A THREE-DIMENSIONAL STRUCTURE WITH PIECEWISE-CONSTANT PHYSICAL AND GEOMETRICAL PARAMETERS ALONGSIDE THE BASIC DIRECTION WITHIN THE FRAMEWORK OF THE DISCRETE-CON

    Directory of Open Access Journals (Sweden)

    Akimov Pavel Alekseevich

    2012-10-01

    Full Text Available The proposed paper covers the operator-related formulation of the eigenvalue problem of analysis of a three-dimensional structure that has piecewise-constant physical and geometrical parameters alongside the so-called basic direction within the framework of a discrete-continual approach (a discrete-continual finite element method, a discrete-continual variation method. Generally, discrete-continual formulations represent contemporary mathematical models that become available for computer implementation. They make it possible for a researcher to consider the boundary effects whenever particular components of the solution represent rapidly varying functions. Another feature of discrete-continual methods is the absence of any limitations imposed on lengths of structures. The three-dimensional problem of elasticity is used as the design model of a structure. In accordance with the so-called method of extended domain, the domain in question is embordered by an extended one of an arbitrary shape. At the stage of numerical implementation, relative key features of discrete-continual methods include convenient mathematical formulas, effective computational patterns and algorithms, simple data processing, etc. The authors present their formulation of the problem in question for an isotropic medium with allowance for supports restrained by elastic elements while standard boundary conditions are also taken into consideration.

    2011-01-01

    从简化的一维双区平板反应堆问题入手,专门对松散耦合反应堆系统的基本物理特性进行了研究.结果表明,一个由多区燃料组成的反应堆系统,当各区之间的耦合非常弱时,其反应性将完全由系统内反应性最大的区域所决定,其余区域对系统的反应性没有贡献.此外,研究还表明,一个由外源驱动的次临界弱耦合反应堆系统其中子注量率信息只反映外源中子所在区域局部的反应性大小,而非整个系统的反应性.%Based on a simplified one-dimensional two-fuel-plates reactor core model, the basic physics characteristics of a loosely-coupled reactor system is investigated. Numerical results demonstrate that for a multi-region reactor system, when the region-to-region coupling is weak, the system k-effective is fully dominated by the region with the highest reactivity, while other regions do not contribute the system reactivity at all. Moreover, numerical results also reveal that for a subcritical loosely-coupled reactor system driven by an external neutron source, the information of system flux just reflects the local reactivity of the region where the external source is inserted, not the global one of the system.

  14. Engaging the community through an undergraduate biomedical physics course

    Science.gov (United States)

    Van Ness, G. R.; Widenhorn, Ralf

    2012-12-01

    We report on the development of an undergraduate biomedical physics course at Portland State University, motivated by both student interest and the desire of the university's Physics Department to provide an interdisciplinary intermediate-level physics course. The course was developed through the community engagement of physicians, clinical researchers, and basic science researchers. Class meetings were a combination of regular and guest lectures, hands-on exercises, web-based activities, class discussions, and a student poster information session for patrons at a local science museum. The course inspired students to engage in research projects in biomedical physics that enhance their understanding of science and education as well as benefit the learning of future students. Furthermore, this course offers an opportunity for traditionally underrepresented groups in physics courses, such as women, to gain additional exposure to physics.

  15. A Tracing Analysis of the Basic Teaching Skills Competition for Young Physical Education Teachers in College%对高校青年体育教师教学基本功大赛的追踪分析

    2015-01-01

    In order to comprehensively promote quality education,improve young P. E. teachers’ comprehensive pro-fessional quality,accelerate the extensive communication in sports teaching and research in colleges and universi-ties,the present study looked at the Basic Teaching skills Competition for Young Physical Education Teachers in College in Tianjin,using literature searches,expert interviews and mathematical statistics. The results showed that the number of participating colleges and universities and participants declined due to the influence of the competi-tion rules,and that the item setting and marking criteria need to be further improved. The difference in the total score and the“lesson plan speaking”scores of lectures and assistants between the past two competitions was signifi-cant(P<0. 01). Female teachers scored higher than their male counterparts in the five items,but with a low partici-pation. The total score was in high correlation with the score for“lesson plan speaking”,major items and minor i-tems,but in low correlation with the other scores. This paper suggests that Tianjin should draw inspirations from suc-cessful competitions in Shandong,Shanxi,Yunnan and other provinces and accumulate information for the holding of the First National Competition for Young P. E. Teachers in College.%为全面推进素质教育,切实提高高校青年体育教师的综合业务素质,促进高校体育教学、科研的广泛交流,运用文献资料法、专家访谈法、数理统计法对天津市高校青年体育教师教学基本功大赛的经验与不足进行了总结与分析。结果表明:基本功大赛受竞赛规程影响,参赛院校和参赛人数有所下降,参赛项目设置、评分标准有待进一步完善;近两届比赛总成绩、讲师与助教说课成绩差异非常显著(P<0.01),女子组五项成绩均高于男子组但参赛人数比例偏低;总成绩与说课、主项、副项成绩高度相关,与其

    2014-05-01

    We present a brief overview of nuclear multifragmentation reaction. Basic formalism of canonical thermodynamical model based on equilibrium statistical mechanics is described. This model is used to calculate basic observables of nuclear multifragmentation like mass distribution, fragment multiplicity, isotopic distribution and isoscaling. Extension of canonical thermodynamical model to a projectile fragmentation model is outlined. Application of the projectile fragmentation model for calculating average number of intermediate mass fragments and the average size of the largest cluster at different bound, differential charge distribution and cross-section of neutron-rich nuclei of different projectile fragmentation reactions at different energies are described. Application of nuclear multifragmentation reaction in basic research as well as in other domains is outlined.

    My invitation from this Journal's Editor, Felicia Cox, to provide a paper for this themed issue, included the sentence 'I was wondering if you or a colleague would like to contribute a back to basics article on the relevant standards and guidelines for decontamination, including what is compliance?'. The reason it is so interesting to me is that the term 'back to basics' implies reverting to a simpler time in life - when by just sticking to the rules, life became easier. However, with decontamination this is not actually true.

    CERN Document Server

    Buckley, P M

    1980-01-01

    In the past, the teaching of electricity and electronics has more often than not been carried out from a theoretical and often highly academic standpoint. Fundamentals and basic concepts have often been presented with no indication of their practical appli­ cations, and all too frequently they have been illustrated by artificially contrived laboratory experiments bearing little relationship to the outside world. The course comes in the form of fourteen fairly open-ended constructional experiments or projects. Each experiment has associated with it a construction exercise and an explanation. The basic idea behind this dual presentation is that the student can embark on each circuit following only the briefest possible instructions and that an open-ended approach is thereby not prejudiced by an initial lengthy encounter with the theory behind the project; this being a sure way to dampen enthusiasm at the outset. As the investigation progresses, questions inevitably arise. Descriptions of the phenomena encounte...

    CERN Document Server

    Blyth, T S

    2002-01-01

    Basic Linear Algebra is a text for first year students leading from concrete examples to abstract theorems, via tutorial-type exercises. More exercises (of the kind a student may expect in examination papers) are grouped at the end of each section. The book covers the most important basics of any first course on linear algebra, explaining the algebra of matrices with applications to analytic geometry, systems of linear equations, difference equations and complex numbers. Linear equations are treated via Hermite normal forms which provides a successful and concrete explanation of the notion of linear independence. Another important highlight is the connection between linear mappings and matrices leading to the change of basis theorem which opens the door to the notion of similarity. This new and revised edition features additional exercises and coverage of Cramer's rule (omitted from the first edition). However, it is the new, extra chapter on computer assistance that will be of particular interest to readers:...

  9. Basics of RF electronics

    CERN Document Server

    Gallo, A

    2011-01-01

    RF electronics deals with the generation, acquisition and manipulation of high-frequency signals. In particle accelerators signals of this kind are abundant, especially in the RF and beam diagnostics systems. In modern machines the complexity of the electronics assemblies dedicated to RF manipulation, beam diagnostics, and feedbacks is continuously increasing, following the demands for improvement of accelerator performance. However, these systems, and in particular their front-ends and back-ends, still rely on well-established basic hardware components and techniques, while down-converted and acquired signals are digitally processed exploiting the rapidly growing computational capability offered by the available technology. This lecture reviews the operational principles of the basic building blocks used for the treatment of high-frequency signals. Devices such as mixers, phase and amplitude detectors, modulators, filters, switches, directional couplers, oscillators, amplifiers, attenuators, and others are d...

    2013-09-01

    After WTG Morton's first public demonstration in 1846 of use of ether as an anaesthetic agent, for many years anaesthesiologists did not require a machine to deliver anaesthesia to the patients. After the introduction of oxygen and nitrous oxide in the form of compressed gases in cylinders, there was a necessity for mounting these cylinders on a metal frame. This stimulated many people to attempt to construct the anaesthesia machine. HEG Boyle in the year 1917 modified the Gwathmey's machine and this became popular as Boyle anaesthesia machine. Though a lot of changes have been made for the original Boyle machine still the basic structure remains the same. All the subsequent changes which have been brought are mainly to improve the safety of the patients. Knowing the details of the basic machine will make the trainee to understand the additional improvements. It is also important for every practicing anaesthesiologist to have a thorough knowledge of the basic anaesthesia machine for safe conduct of anaesthesia.

  20. Tests and prospects of new physics at very high energy. Beyond the standard basic principles, and beyond conventional matter and space-time. On the possible origin of Quantum Mechanics.

    Directory of Open Access Journals (Sweden)

    Gonzalez-Mestres Luis

    2015-01-01

    Full Text Available Recent results and announcements by Planck and BICEP2 have led to important controversies in the fields of Cosmology and Particle Physics. As new ideas and alternative approaches can since then more easily emerge, the link between the Mathematical Physics aspects of theories and the interpretation of experimental results becomes more direct. This evolution is also relevant for Particle Physics experiments at very high energy, where the interpretation of data on the highest-energy cosmic rays remains a major theoretical and phenomenological challenge. Alternative particle physics and cosmology can raise fundamental questions such as that of the structure of vacuum and space-time. In particular, the simplified description of the physical vacuum contained in standard quantum field theory does not necessarily correspond to reality at a deeper level, and similarly for the relativistic space-time based on four real variables. In a more general approach, the definition itself of vacuum can be a difficult task. The spinorial space-time (SST we suggested in 1996-97 automatically incorporates a local privileged space direction (PSD for each comoving observer, possibly leading to a locally anisotropic vacuum structure. As the existence of the PSD may have been confirmed by Planck, and a possible discovery of primordial B-modes in the polarization of the cosmic microwave background radiation (CMB may turn out to contain new evidence for the SST, we explore other possible implications of this approach to space-time. The SST structure can naturally be at the origin of Quantum Mechanics at distance scales larger than the fundamental one if standard particles are dealt with as vacuum excitations. We also discuss possible implications of our lack of knowledge of the structure of vacuum, as well as related theoretical, phenomenological and cosmological uncertainties. Pre-Big Bang scenarios and new ultimate constituents of matter (including superbradyons are

    The U.S. Department of Energy’s (DOE) Office of Basic Energy Sciences (BES) supports fundamental research to understand, predict, and ultimately control matter and energy at the electronic, atomic, and molecular levels to provide the foundations for new energy technologies and to support DOE missions in energy, environment, and national security. The research disciplines covered by BES—condensed matter and materials physics, chemistry, geosciences, and aspects of physical biosciences— are those that discover new materials and design new chemical processes. These disciplines touch virtually every aspect of energy resources, production, conversion, transmission, storage, efficiency, and waste mitigation. BES also plans, constructs, and operates world-class scientific user facilities that provide outstanding capabilities for imaging and spectroscopy, characterizing materials of all kinds ranging from hard metals to fragile biological samples, and studying the chemical transformation of matter. These facilities are used to correlate the microscopic structure of materials with their macroscopic properties and to study chemical processes. Such experiments provide critical insights to electronic, atomic, and molecular configurations, often at ultrasmall length and ultrafast time scales.

    This review is based on a case report that concerns a young female athlete who experienced some of the negative aspects of exercise. Overtraining, a negative byproduct of excessive exercise, can turn the positive psychosocial and physiologic benefits of regular physical activity into an activity detrimental to one's health. With the proper psychological skills and appropriate exercise regimen, these negatives can be turned into positives. Once learned, the psychosocial benefits of exercise, as well as the positive implications, will become more prevalent, similar to the way in which proper physical training helps one become more fit over time.

    This project had two major goals. Final Goal: obtain spectrally resolved, absolutely calibrated x-ray emission data from uniquely uniform mm-scale near-critical-density high-Z plasmas not in local thermodynamic equilibrium (LTE) to benchmark modern detailed atomic physics models. Scientific significance: advance understanding of non-LTE atomic physics. Intermediate Goal: develop new nano-fabrication techniques to make suitable laser targets that form the required highly uniform non-LTE plasmas when illuminated by high-intensity laser light. Scientific significance: advance understanding of nano-science. The new knowledge will allow us to make x-ray sources that are bright at the photon energies of most interest for testing radiation hardening technologies, the spectral energy range where current x-ray sources are weak. All project goals were met.

    2007-10-01

    Full Text Available Currently Indonesia is the world largest palm oil producer with production volume reaching 16 million tones per annum. The high crude oil and ethylene prices in the last 3 – 4 years contribute to the healthy demand growth for basic oleochemicals: fatty acids and fatty alcohols. Oleochemicals are starting to replace crude oil derived products in various applications. As widely practiced in petrochemical industry, catalyst plays a very important role in the production of basic oleochemicals. Catalytic reactions are abound in the production of oleochemicals: Nickel based catalysts are used in the hydrogenation of unsaturated fatty acids; sodium methylate catalyst in the transesterification of triglycerides; sulfonic based polystyrene resin catalyst in esterification of fatty acids; and copper chromite/copper zinc catalyst in the high pressure hydrogenation of methyl esters or fatty acids to produce fatty alcohols. To maintain long catalyst life, it is crucial to ensure the absence of catalyst poisons and inhibitors in the feed. The preparation methods of nickel and copper chromite catalysts are as follows: precipitation, filtration, drying, and calcinations. Sodium methylate is derived from direct reaction of sodium metal and methanol under inert gas. The sulfonic based polystyrene resin is derived from sulfonation of polystyrene crosslinked with di-vinyl-benzene. © 2007 BCREC UNDIP.

    Hawkins, Shannon M.; Matzuk, Martin M.

    2010-01-01

    The basic biology of the menstrual cycle is a complex, coordinated sequence of events involving the hypothalamus, anterior pituitary, ovary, and endometrium. The menstrual cycle with all its complexities can be easily perturbed by environmental factors such as stress, extreme exercise, eating disorders, and obesity. Furthermore, genetic influences such as fragile X premutations (Chapter X), X chromosome abnormalities (Chapter X), and galactose-1-phosphate uridyltransferase (GALT) point mutations (galactosemia) also contribute to perturbations of the menstrual cycle. Although not perfect, mouse model have helped to identify and confirm additional components and pathways in menstrual cycle function and dysfunction in humans. PMID:18574203

    The Workshop on Defense, Basic, and Industrial Research at the Los Alamos Neutron Science Center gathered scientists from Department of Energy national laboratories, other federal institutions, universities, and industry to discuss the use of neutrons in science-based stockpile stewardship, The workshop began with presentations by government officials, senior representatives from the three weapons laboratories, and scientific opinion leaders. Workshop participants then met in breakout sessions on the following topics: materials science and engineering; polymers, complex fluids, and biomaterials; fundamental neutron physics; applied nuclear physics; condensed matter physics and chemistry; and nuclear weapons research. They concluded that neutrons can play an essential role in science-based stockpile stewardship and that there is overlap and synergy between defense and other uses of neutrons in basic, applied, and industrial research from which defense and civilian research can benefit. This proceedings is a collection of talks and papers from the plenary, technical, and breakout session presentations. Selected papers are indexed separately for inclusion in the Energy Science and Technology Database.

  3. Quality quantification model of basic raw materials

    2016-07-01

    Full Text Available Basic raw materials belong to the key input sources in the production of pig iron. The properties of basic raw materials can be evaluated using a variety of criteria. The essential ones include the physical and chemical properties. Current competitive pressures, however, force the producers of iron more and more often to include cost and logistic criteria into the decision-making process. In this area, however, they are facing a problem of how to convert a variety of vastly different parameters into one evaluation indicator in order to compare the available raw materials. This article deals with the analysis of a model created to evaluate the basic raw materials, which was designed as part of the research.

  4. Human milk benefits and breastfeeding

    Directory of Open Access Journals (Sweden)

    Fani Anatolitou

    2012-10-01

    Full Text Available Human milk is uniquely superior for infant feeding and represents the perfect example of individualization in Pediatrics. Human milk is not a uniform body fluid but a secretion of the mammary gland of changing composition. Foremilk differs from hindmilk, and colostrum is strikingly different from transitional and mature milk. Milk changes with time of day and during the course of lactation. Extensive research has demonstrated health, nutritional, immunologic, developmental, psychological, social, economic and environmental benefits of human milk. Breastfeeding results in improved infant and maternal health outcomes in both the industrialized and developing world. Some specific topics will be discussed such as the preventive effect of human milk on infections, overweight, obesity and diabetes, malignant disease, neurodevelopmental outcomes, reduction of necrotizing enterocolitis. Important health benefits of breastfeeding and lactation are also described for mothers. Finally, contraindications to breastfeeding and supplementation of breastfed infants are presented. Interventions to promote breastfeeding are relatively simple and inexpensive. Infant feeding should not be regarded as a lifestyle choice but rather as a basic health issue.

    Progress in immunology continues to grow exponentially every year. New applications of this knowledge are being developed for a broad range of clinical conditions. Conversely, the study of primary and secondary immunodeficiencies is helping to elucidate the intricate mechanisms of the immune system. We have selected a few of the most significant contributions to the fields of basic and clinical immunology published between October 2001 and October 2002. Our choice of topics in basic immunology included the description of T-bet as a determinant factor for T(H)1 differentiation, the role of the activation-induced cytosine deaminase gene in B-cell development, the characterization of CD4(+)CD25(+) regulatory T cells, and the use of dynamic imaging to study MHC class II transport and T-cell and dendritic cell membrane interactions. Articles related to clinical immunology that were selected for review include the description of immunodeficiency caused by caspase 8 deficiency; a case series report on X-linked agammaglobulinemia; the mechanism of action, efficacy, and complications of intravenous immunoglobulin; mechanisms of autoimmunity diseases; and advances in HIV pathogenesis and vaccine development. We also reviewed two articles that explore the possible alterations of the immune system caused by spaceflights, a new field with increasing importance as human space expeditions become a reality in the 21st century.

    Many optical design technical books are available for many years which mainly deal with image optics design based on geometric optics and using sequential raytracing technique. Some books slightly touched laser beam manipulation optics design. On the other hand many books on laser diodes have been published that extensively deal with laser diode physics with little touching on laser diode beam manipulations and characterizations. There are some internet resources dealing with laser diode beams. However, these internet resources have not covered enough materials with enough details on laser diode beam manipulations and characterizations. A technical book concentrated on laser diode beam manipulations and characterizations can fit in to the open and provide useful information to laser diode users.

  16. Anisotropic hydrodynamics -- basic concepts

    CERN Document Server

    Florkowski, Wojciech; Ryblewski, Radoslaw; Strickland, Michael

    2013-01-01

    Due to the rapid longitudinal expansion of the quark-gluon plasma created in relativistic heavy ion collisions, potentially large local rest frame momentum-space anisotropies are generated. The magnitude of these momentum-space anisotropies can be so large as to violate the central assumption of canonical viscous hydrodynamical treatments which linearize around an isotropic background. In order to better describe the early-time dynamics of the quark gluon plasma, one can consider instead expanding around a locally anisotropic background which results in a dynamical framework called anisotropic hydrodynamics. In this proceedings contribution we review the basic concepts of the anisotropic hydrodynamics framework presenting viewpoints from both the phenomenological and microscopic points of view.

    Die Entscheidung, einen zeit- bzw. ereignisgesteuerten Ansatz für ein Echtzeitsystem zu verwenden, ist schwierig und sehr weitreichend. Weitreichend vor allem deshalb, weil diese beiden Ansätze mit äußerst unterschiedlichen Kontrollflussabstraktionen verknüpft sind, die eine spätere Migration zum anderen Paradigma sehr schwer oder gar unmöglich machen. Wir schlagen daher die Verwendung einer Zwischendarstellung vor, die unabhängig von der jeweils verwendeten Kontrollflussabstraktion ist. Für diesen Zweck verwenden wir auf Basisblöcken basierende Atomic Basic Blocks (ABB) und bauen darauf ein Werkzeug, den Real-Time Systems Compiler (RTSC) auf, der die Migration zwischen zeit- und ereignisgesteuerten Systemen unterstützt.

    CERN Document Server

    Cornish-Bowden, Athel

    1981-01-01

    Some teachers of biochemistry think it positively beneficial for students to struggle with difficult mathematics. I do not number myself among these people, although I have derived much personal pleasure from the study of mathematics and from applying it to problems that interest me in biochemistry. On the contrary, I think that students choose courses in biochemistry out of interest in biochemistry and that they should not be encumbered with more mathematics than is absolutely required for a proper understanding of biochemistry. This of course includes physical chemistry, because a biochemist ignorant of physical chemistry is no biochemist. I have been guided by these beliefs in writing this book. I have laid heavy emphasis on those topics, such as the use of logarithms, that play an important role in biochemistry and often cause problems in teaching; I have ignored others, such as trigonometry, that one can manage without. The proper treatment of statistics has been more difficult to decide. Although it cle...

    Cairns, R A

    1985-01-01

    This book is intended as an introduction to plasma physics at a level suitable for advanced undergraduates or beginning postgraduate students in physics, applied mathematics or astrophysics. The main prerequisite is a knowledge of electromagnetism and of the associated mathematics of vector calculus. SI units are used throughout. There is still a tendency amongst some plasma physics researchers to· cling to C.g.S. units, but it is the author's view that universal adoption of SI units, which have been the internationally agreed standard since 1960, is to be encouraged. After a short introductory chapter, the basic properties of a plasma con­ cerning particle orbits, fluid theory, Coulomb collisions and waves are set out in Chapters 2-5, with illustrations drawn from problems in nuclear fusion research and space physics. The emphasis is on the essential physics involved and (he theoretical and mathematical approach has been kept as simple and intuitive as possible. An attempt has been made to draw attention t...

    Psychodermatology is a relatively new field of medicine. It encompasses the interaction of mind and skin. The role of psychoneuroimmunology in the causation of psychocutaneous disorders and psychosocial aspects of skin disease have gained momentum lately. The treatment of psychodermatological disorders focus on improving function, reducing physical distress, diagnosing and treating depression and anxiety associated with skin disease, managing social isolation and improving self esteem of the patient. Both pharmacological and psychological interventions are used in treating psychocutaneous disorders. The interest in Psychodermatology around the world is increasing and there are several organizations holding their regular meetings.

  4. Basics of aerothermodynamics

    Hirschel, Ernst Heinrich

    2015-01-01

    This successful book gives an introduction to the basics of aerothermodynamics, as applied in particular to winged re-entry vehicles and airbreathing hypersonic cruise and acceleration vehicles. The book gives a review of the issues of transport of momentum, energy and mass, real-gas effects as well as inviscid and viscous flow phenomena. In this second, revised edition the chapters with the classical topics of aerothermodynamics more or less were left untouched. The access to some single topics of practical interest was improved. Auxiliary chapters were put into an appendix. The recent successful flights of the X-43A and the X-51A indicate that the dawn of sustained airbreathing hypersonic flight now has arrived. This proves that the original approach of the book to put emphasis on viscous effects and the aerothermodynamics of radiation-cooled vehicle surfaces was timely. This second, revised edition even more accentuates these topics. A new, additional chapter treats examples of viscous thermal surface eff...

    2008-11-01

    This is a review of the articles dealing with basic science published in recent issues of Archivos de Bronconeumología. Of particular interest with regard to chronic obstructive pulmonary disease were an article on extrapulmonary inflammation and oxidative stress and another on bronchial remodeling. The articles relating to asthma included a review on the use of drugs that block free immunoglobulin-E and an article about the contribution of experimental models to our knowledge of this disease. Two of the most interesting articles on the topic of lung cancer dealt with gene therapy and resistance to chemotherapy. Also notable were 2 studies that investigated ischemia-reperfusion injury. One evaluated tissue resistance to injury while the other analyzed the role played by interleukin-8 in this process. On the topic of pulmonary fibrosis, an article focused on potential biomarkers of progression and prognosis; others dealt with the contribution of experimental models to our understanding of this disorder and the fibrogenic role of transforming growth factor b. In the context of both sleep apnea syndrome and pulmonary infection, studies investigating the role of oxidative stress were published. Finally, 2 studies analyzed the diagnosis and treatment of tuberculosis and other pulmonary infections.

    Gastric cancer (GC) is a world health burden, ranging as the second cause of cancer death worldwide. Etiologically, GC arises not only from the combined effects of environmental factors and susceptible genetic variants but also from the accumulation of genetic and epigenetic alterations. In the last years, molecular oncobiology studies brought to light a number of genes that are implicated in gastric carcinogenesis. This review is intended to focus on the recently described basic aspects that play key roles in the process of gastric carcinogenesis. Genetic variants of the genes IL-10, IL-17, MUC1, MUC6, DNMT3B, SMAD4, and SERPINE1 have been reported to modify the risk of developing GC. Several genes have been newly associated with gastric carcinogenesis, both through oncogenic activation (GSK3β, CD133, DSC2, P-Cadherin, CDH17, CD168, CD44, metalloproteinases MMP7 and MMP11, and a subset of miRNAs) and through tumor suppressor gene inactivation mechanisms (TFF1, PDX1, BCL2L10, XRCC, psiTPTE-HERV, HAI-2, GRIK2, and RUNX3). It also addressed the role of the inflammatory mediator cyclooxygenase-2 (COX-2) in the process of gastric carcinogenesis and its importance as a potential molecular target for therapy.

    2001-01-01

    rii application of linear operators on a Hilbert space. We begin with a chapter on the geometry of Hilbert space and then proceed to the spectral theory of compact self adjoint operators; operational calculus is next presented as a nat­ ural outgrowth of the spectral theory. The second part of the text concentrates on Banach spaces and linear operators acting on these spaces. It includes, for example, the three 'basic principles of linear analysis and the Riesz­ Fredholm theory of compact operators. Both parts contain plenty of applications. All chapters deal exclusively with linear problems, except for the last chapter which is an introduction to the theory of nonlinear operators. In addition to the standard topics in functional anal­ ysis, we have presented relatively recent results which appear, for example, in Chapter VII. In general, in writ­ ing this book, the authors were strongly influenced by re­ cent developments in operator theory which affected the choice of topics, proofs and exercises. One ...

    2005-06-01

    Full Text Available The goal of grounded theory is to generate a theory that accounts for a pattern of behavior that is relevant and problematic for those involved. The goal is not voluminous description, nor clever verification. As with all grounded theory, the generation of a basic social process (BSP theory occurs around a core category. While a core category is always present in a grounded research study, a BSP may not be.BSPs are ideally suited to generation by grounded theory from qualitative research because qualitative research can pick up process through fieldwork that continues over a period of time. BSPs are a delight to discover and formulate since they give so much movement and scope to the analyst’s perception of the data. BSPs such as cultivating, defaulting, centering, highlighting or becoming, give the feeling of process, change and movement over time. They also have clear, amazing general implications; so much so, that it is hard to contain them within the confines of a single substantive study. The tendency is to refer to them as a formal theory without the necessary comparative development of formal theory. They are labeled by a “gerund”(“ing” which both stimulates their generation and the tendency to over-generalize them.

    Osteoarthritis (OA) is a prevalent, disabling disorder of the joints that affects a large population worldwide and for which there is no definitive cure. This review provides critical insights into the basic knowledge on OA that may lead to innovative end efficient new therapeutic regimens. While degradation of the articular cartilage is the hallmark of OA, with altered interactions between chondrocytes and compounds of the extracellular matrix, the subchondral bone has been also described as a key component of the disease, involving specific pathomechanisms controlling its initiation and progression. The identification of such events (and thus of possible targets for therapy) has been made possible by the availability of a number of animal models that aim at reproducing the human pathology, in particular large models of high tibial osteotomy (HTO). From a therapeutic point of view, mesenchymal stem cells (MSCs) represent a promising option for the treatment of OA and may be used concomitantly with functional substitutes integrating scaffolds and drugs/growth factors in tissue engineering setups. Altogether, these advances in the fundamental and experimental knowledge on OA may allow for the generation of improved, adapted therapeutic regimens to treat human OA.

  10. Basic Data on Biogas

    Renewable gases such as biogas and biomethane are considered as key energy carrier when the society is replacing fossil fuels with renewable alternatives. In Sweden, almost 80 % of the fossil fuels are used in the transport sector. Therefore, the focus in Sweden has been to use the produced biogas in this sector as vehicle gas. Basic Data on Biogas contains an overview of production, utilisation, climate effects etc. of biogas from a Swedish perspective. The purpose is to give an easy overview of the current situation in Sweden for politicians, decision makers and interested public. 1.4 TWh of biogas is produced annually in Sweden at approximately 230 facilities. The 135 wastewater treatment plants that produce biogas contribute with around half of the production. In order to reduce the sludge volume, biogas has been produced at wastewater treatment plants for decades. New biogas plants are mainly co-digestion plants and farm plants. The land filling of organic waste has been banned since 2005, thus the biogas produced in landfills is decreasing.

  11. Quasi-homogenous approximation for description of the properties of dispersed systems. The basic approaches to model hardening processes in nanodispersed silica systems. Part 2. The hardening processes from the standpoint of statistical physics

    Full Text Available The paper deals with possibilities to use quasi-homogenous approximation for discription of properties of dispersed systems. The authors applied statistical polymer ethod based on consideration of average structures of all possible macromolecules of the same weight. The equiations which allow evaluating many additive parameters of macromolecules and the systems with them were deduced. Statistical polymer method makes it possible to model branched, cross-linked macromolecules and the systems with them which are in equilibrium or non-equilibrium state. Fractal analysis of statistical polymer allows modeling different types of random fractal and other objects examined with the mehods of fractal theory. The method of fractal polymer can be also applied not only to polymers but also to composites, gels, associates in polar liquids and other packaged systems. There is also a description of the states of colloid solutions of silica oxide from the point of view of statistical physics. This approach is based on the idea that colloid solution of silica dioxide – sol of silica dioxide – consists of enormous number of interacting particles which are always in move. The paper is devoted to the research of ideal system of colliding but not interacting particles of sol. The analysis of behavior of silica sol was performed according to distribution Maxwell-Boltzmann and free path length was calculated. Using this data the number of the particles which can overcome the potential barrier in collision was calculated. To model kinetics of sol-gel transition different approaches were studied.

    Despite the fact that countless patients suffer from anal problems, there tends to be a lack of understanding of anal health care. Unfortunately, this leads to incorrect diagnoses and treatments. When treating a patient with an anal complaint, the primary goals are to first diagnose the etiology of the symptoms correctly, then to provide an effective and appropriate treatment strategy.The first step in this process is to take an accurate history and physical examination. Specific questions include details about bowel habits, anal hygiene, and fiber supplementation. Specific components of the physical examination include an external anal examination, a digital rectal examination, and anoscopy if appropriate.Common diagnoses include pruritus ani, anal fissures, hemorrhoids, anal abscess or fistula, fecal incontinence, and anal skin tags. However, each problem presents differently and requires a different approach for management. It is of paramount importance that the correct diagnosis is reached. Common errors include an inaccurate diagnosis of hemorrhoids when other pathology is present and subsequent treatment with a steroid product, which is harmful to the anal area.Most of these problems can be avoided by improving bowel habits. Adequate fiber intake with 30 g to 40 g daily is important for many reasons, including improving the quality of stool and preventing colorectal and anal diseases.In this Special Report, we provide an overview of commonly encountered anal problems, their presentation, initial treatment options, and recommendations for referral to specialists.

    Urinary incontinence (UI) is a widely prevalent problem that affects people of all ages and levels of physical health, both in healthcare settings and in the community. Contributing to the problem are that many practitioners remain uneducated about this condition, individuals are often too ashamed or embarrassed to seek professional help, and there are significant variations in diagnostic and treatment practices. Five types of UI are stress, urge, overflow, functional and manufactured incontinence. Stress, urge and overflow are caused by factors within the urinary tract and will be concentrated on in this article. To diagnose UI a three-part assessment should be conducted, including the patient history, physical examination, and urinalysis. A behavioral program should be designed which incorporates identification and education for both patient and clinician. Treatment options include pelvic floor exercises (Kegel), vaginal cones, bladder training (retraining), habit training (timed voiding), electrostimulation and biofeedback, clean intermittent catheterization, indwelling catheters, medications, collagen injections, surgery, and absorption products. Most patients can be helped dramatically or cured with the appropriate treatment.

    Cowley, Steven

    There have been relatively few good textbooks on plasma physics. Most become simple reference books that might be titled, “Plasma Physics Recipes.” Despite their utility such books do not make good textbooks. For teaching, one needs a book that shows how the basic results and models are part of a coherent whole. Richard Hazeltine and Francois Waelbroeck have written such a textbook: The Framework of Plasma PhysicsAn this book, plasma physics is developed carefully and logically from basic physics principles. The book is not, however, overly formal; physical arguments are used to reduce mathematical complexity.

    Physical activity (PA) interventions to improve the physical function of older adults with schizophrenia are necessary but not available. Older adults with schizophrenia may have unique barriers and facilitators to PA. The purpose of this study was to describe the perceptions of older adults with schizophrenia about barriers and facilitators to engage in physical activities that promote physical function. We conducted qualitative interviews with 16 older adults with schizophrenia. Data were collected and analyzed with grounded theory methodology. Participants expressed interest in becoming more physically active for a variety of perceived benefits including psychiatric symptom management and maintenance of basic function. Key barriers and facilitators to PA emerged in five broad categories: Mental Health, No longer a spring chicken, Pride and Sense of Well-being, Comfort and Safety, and Belonging. Interventions in this population should address negative attitudes towards aging and promote routine physical activities that enhance well-being and companionship.

  20. Basics of quantum plasmonics

    Hieu Nguyen, Van; Nguyen, Bich Ha

    2015-01-01

    The present work is a topical review of the theoretical research on the quantum theory of plasmons and plasmon-photon interaction. The plasmons are defined as the quanta of the quantized plasmonic field. The corresponding classical plasmonic field was constructed on the basis of the study of collective oscillations of the electron gas in the solid. The electron-electron Coulomb interaction is taken into account. The explicit forms of the plasmon-photon interaction Lagrangian in canonical quantum mechanics and the plasmon-photon interaction action functional in the functional integral approach are derived. They all show that the interaction processes are nonlocal ones. The physical origin of the nonlocality is the complex structure of plasmons as composite quasiparticles: they cannot be considered as point particles, as was assumed in all phenomenological theories.
