    Given the rise in US obesity rates in adulthood, efforts are needed to assess physical activity engagement during the college years as a strategy to promote a lifetime of being physically active. This study identifies the reasons incoming college freshman enrolled in basic physical education activity courses (BPEAC) and the perceived benefits they anticipated receiving as a result of course participation. Data collected from 302 college freshmen in September 2013 were analyzed. A paper-based questionnaire was administered to 78% of BPEAC sections offered at a large Southeastern University. Frequencies were presented for all participants, which were then compared by sex and course type. Kappa statistics were calculated to examine the concordance between participants' reasons for enrolling in the course and the benefits they anticipated from course enrollment. Diverse physical, mental, social, and academic reasons for enrolling in BPEAC were reported by study participants. Varied anticipated benefits from course participation were reported as well. Reported enrollment reasons and anticipated benefits differed by sex and course type. High concordance between matched enrollment reasons and anticipated benefits was observed. Implications highlight the need for universities to provide quality BPEAC, promote high-quality instruction, and offer a wide variety of physical education courses to meet the diverse needs of students.

  3. Benefits of physical exercise on basic visuo-motor functions across age

    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...

    To become an expert in this field, radiographer must first master in radiation physics. That why the second chapter discussed on radiation physic. The topic that must covered such as atom and molecule, atomic structure, proton, isotope, half life, types of radiation and some basic formula such as formula for shielding, half life, half value layer, tenth value layer and more. All of this must be mastered by radiographer if they want to know more detail on this technique because this technique was a combination of theory and practical. Once they failed the theory they cannot go further on this technique. And to master this technique, once cannot depend on theory only. So, for this technique theory and practical must walk together.

  14. Just caring: defining a basic benefit package.

    Fleck, Leonard M

    2011-12-01

    What should be the content of a package of health care services that we would want to guarantee to all Americans? This question cannot be answered adequately apart from also addressing the issue of fair health care rationing. Consequently, as I argue in this essay, appeal to the language of "basic," "essential," "adequate," "minimally decent," or "medically necessary" for purposes of answering our question is unhelpful. All these notions are too vague to be useful. Cost matters. Effectiveness matters. The clinical circumstances of a patient matters. But what we must ultimately determine is what we mutually agree are the just claims to needed health care of each American in a relatively complex range of clinical circumstances. Answering this question will require a public moral conversation, a fair process of rational democratic deliberation aimed at defining both just claims to needed health care and just limits.

    The technologies used in nuclear medicine for diagnostic imaging have evolved over the last century, starting with Röntgen’s discovery of X rays and Becquerel’s discovery of natural radioactivity. Each decade has brought innovation in the form of new equipment, techniques, radiopharmaceuticals, advances in radionuclide production and, ultimately, better patient care. All such technologies have been developed and can only be practised safely with a clear understanding of the behaviour and principles of radiation sources and radiation detection. These central concepts of basic radiation physics and nuclear physics are described in this chapter and should provide the requisite knowledge for a more in depth understanding of the modern nuclear medicine technology discussed in subsequent chapters.

    1999-01-01

    The basic physical principles behind the well-established but also developing practice of neutron scattering experiments are presented. A few examples are given either to illustrate the physical principles or to give an idea of the variety, importance or magnitude of various phenomena. The evolution of neutron scattering experimental techniques is investigated from a special aspect: the increasing capability of taking into account more and more important and sometimes decisive finer details by using more and more realistic mathematical models of the evolution of the neutrons from birth do death, eventually passing by the sample and being scattered more than one times. Working with such numerical 'virtual instruments' one will have to go far beyond notions like resolution function, convolution etc, and actually eliminate a large number of approximations currently in use.

  4. Metabolic benefits of physical activity

    Directory of Open Access Journals (Sweden)

    Špela Volčanšek

    2014-10-01

    Full Text Available Physical activity is the most beneficial intervention in prevention and treatment of chronic diseases. Life style, which has become mostly sedentary, leads to growing incidence in obesity, what could cause the first so far reduction in life expectancy in developed countries.Physical activity reduces the chronic low-grade inflammation, which plays an important role in the pathogenesis of type 2 diabetes, cardiovascular disease and certain types of cancer. Regular physical activity exerts two anti-inflammatory effects: reduction of visceral fat, which produces the majority of pro-inflammatory cytokines, and production of myokines. It has been proposed that cytokines and other peptides that are produced by muscle fibers should be classified as myokines that exert autocrine, paracrine and endocrine effects. Myokines induce muscle hypertrophy and myogenesis, stimulate fat oxidation, improve insulin sensitivity and have an anti-inflammatory effect.  Therefore, skeletal muscle has been identified as a secretory organ and this provides the basis for understanding how muscles communicate with other organs, such as adipose tissue, liver, pancreas, gut, bones and brain. Physical inactivity leads to an altered myokine profile, associating sedentary life style with some chronic diseases.Physical activity is recommended as a tool for weight management and prevention of weight gain, for weight loss and for prevention of weight regain. High quality studies have confirmed the important impact of exercise on improving blood glucose control in diabetic patients, and on preventing or delaying the onset of type 2 diabetes in predisposed populations. Prescribing specific exercise tailored to individual's needs is an intervention strategy for health improvement. Physical fitness counteracts the detrimental effects of obesity reducing morbidity and mortality.

  5. 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.

    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. Published by the BMJ Publishing Group Limited.

    Full Text Available Physical activity levels in children have been steadily decreasing in recent years. Reduced physical activity leads to numerous chronic diseases at an early age, particularly obesity. Lifelong participation in physical activity and maintenance of ideal bodyweight are highly effective in the prevention of chronic diseases such as obesity, cardiovascular diseases, hypertension, Type II diabetes, lung and colon cancers. At the same time physical activity increases self-confidence, self-esteem and academic achievement, and reduces symptoms of depression. Therefore, this study was designed to improve awareness of professional groups and families working with children and adolescents about physical activity benefits on children health, as well as psychosocial benefits and planned to offer suggestions for increasing physical activity levels of children.

    2010-01-01

    The basic principles and contents of an integrated management system are presented. The report focuses on the benefits and the experience accumulated in using an integrated management system. Integrated management systems are characterized by 2 features in particular: - On the one hand, by a system holistically controlling and describing all processes within a company which are necessary to achieve the company policy and company goals as defined. - On the other hand, it combines in one integrated management system various different aspects (such as quality, environmental protection, and safety) and the resulting requirements. Successful implementation of an integrated management system requires a clear commitment by company management to the integrated management system serving as a management tool. Implementation must be assigned the appropriate importance in the company. It must not be viewed as an instrument preserving 'status quo.' Instead, it must be seen as a tool for long-term improvement of the company. Application of the integrated management system minimizes the probability of occurrence of events, but is not able to reduce it to zero. (orig.)

    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

    CERN Document Server

    Saller, Heinrich

    2017-01-01

    This book describes the endeavour to relate the particle spectrum with representations of operational electroweak spacetime, in analogy to the atomic spectrum as characterizing representations of hyperbolic space. The spectrum of hyperbolic position space explains the properties of the nonrelativistic atoms; the spectrum of electroweak spacetime is hoped to explain those of the basic interactions and elementary particles. In this book, the theory of operational symmetries is developed from the numbers, from Plato’s and Kepler’s symmetries over the simple Lie groups to their applications in nonrelativistic, special relativistic and general relativistic quantum theories with the atomic spectrum for hyperbolic position and, in first attempts, the particle spectrum for electroweak spacetime. The standard model of elementary particles and interactions is characterized by a symmetry group. In general, as initiated by Weyl and stressed by Heisenberg, quantum theory can be built as a theory of operation groups an...

  4. Basic Physics Questions Addressed by Astrophysics

    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

    "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....

    2011-01-01

    In Basic Structures of Reality, Colin McGinn deals with questions of metaphysics, epistemology, and philosophy of mind from the vantage point of physics. Combining general philosophy with physics, he covers such topics as the definition of matter, the nature of space, motion, gravity, electromagnetic fields, the character of physical knowledge, and consciousness and meaning. Throughout, McGinn maintains an historical perspective and seeks to determine how much we really know of the world described by physics. He defends a version of "structuralism": the thesis that our knowledge is p

    Synthetic peptide monomers can self-assemble into PNM such as nanotubes, nanospheres, hydrogels, etc. which represent a novel class of nanomaterials. Molecular recognition processes lead to the formation of supramolecular PNM ensembles containing crystalline building blocks. Such low-dimensional highly ordered regions create a new physical situation and provide unique physical properties based on electron-hole QC phenomena. In the case of asymmetrical crystalline structure, basic physical phenomena such as linear electro-optic, piezoelectric, and nonlinear optical effects, described by tensors of the odd rank, should be explored. Some of the PNM crystalline structures permit the existence of spontaneous electrical polarization and observation of ferroelectricity. The PNM crystalline arrangement creates highly porous nanotubes when various residues are packed into structural network with specific wettability and electrochemical properties. We report in this review on a wide research of PNM intrinsic physical properties, their electronic and optical properties related to QC effect, unique SHG, piezoelectricity and ferroelectric spontaneous polarization observed in PNT due to their asymmetric structure. We also describe PNM wettability phenomenon based on their nanoporous structure and its influence on electrochemical properties in PNM. The new bottom-up large scale technology of PNT physical vapor deposition and patterning combined with found physical effects at nanoscale, developed by us, opens the avenue for emerging nanotechnology applications of PNM in novel fields of nanophotonics, nanopiezotronics and energy storage devices.

    Physical inactivity not only places women's health at risk during menopause, but also increases menopausal problems. Abundant evidence links habitual physical exercise (PE) to a better status on numerous health indicators and better quality of life and to the prevention and treatment of the ailments that typically occur from mid-life onwards. We can infer that PE is something more than a lifestyle: it constitutes a form of therapy in itself. A panel of experts from various Spanish scientific societies related to PE and menopause (Spanish Menopause Society, Spanish Cardiology Society, Spanish Federation of Sports Medicine) met to reach a consensus on these issues and to decide the optimal timing of and methods of exercise, based on the best evidence available.

    2015-03-01

    With the introduction of the Health Insurance Act in 2006 in the Netherlands, the basic package of the former sickness funds became valid for all citizens. The basic benefit package has been subject to change, responding to increasing health care expenditures, medical innovations and the economic crisis. In this paper we address the decision criteria used to assess the package annually since 2006 and describe some developments that do not follow the criteria, leading to a yo-yo effect. We discuss the formation of the decision for in- or exclusion and why some treatments seem to follow an, at first sight, arbitrary in- and exclusion pathway. We first describe the official way of establishing the basic benefit package and than will describe why some treatments follow a deviated path. We conclude that political pressure and pressure from interest groups may lead to inclusion or postponement of exclusion. Reform of the organization of certain forms of health care (in our example mental care) may lead to seemingly inconsequent changes. The yo-yo effect of some treatments or pharmaceuticals may have negative effects on health care providers, insurers and patients. The seemingly well defined criteria available for defining the basic package appear to be broadly interpretable and other influences may determine the final decision of inclusion or exclusion.

  5. Benefits of reactor physics experiments for the HTGR industrial development - an attempt to a quantitative approach

    Energy Technology Data Exchange (ETDEWEB)

    Cuniberti, R; Graziani, G; Massino, L; Rinaldini, C; Zanantoni, C

    1972-10-15

    The available results of reactor physics experiments on HTGRs and their accuracies are briefiy reviewed. The physical quantities of interest are grouped into three categories: basic nuclear data, lattice parameters and integral design data. The last two are considered and their possible improvements in accuracy by means of experimental measurements are assessed. The cost penalty on fuel cycle and capital cost due to each physical quantity is then considered, and consequently the benefits of reactor physics experiments are evaluated for a number of hypotheses concerning the foreseeable HTGR development and the delay in taking practical advantage of experimental results. It is concluded that, at the present state of knowledge of basic nuclear data and with the available calculation methods, the economic incentive to new reactor physics experiments is small, and a previous careful analysis is recommended to those intending to perform such experiments.

  7. Benefit distribution of social health insurance: evidence from china's urban resident basic medical insurance.

    Pan, Jay; Tian, Sen; Zhou, Qin; Han, Wei

    2016-09-01

    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. © The Author 2016.

    Fasczewski, Kimberly S; Gill, Diane L; Rothberger, Sara M

    2018-06-01

    Multiple sclerosis is a degenerative neurological disease that affects 2.1 million people worldwide. There is no cure, but an expanding body of research supports the positive impact of physical activity and suggests physical activity has benefits for the individual's psychological and physical well-being. Using Self-Determination Theory as a framework, mixed methods with a focus on qualitative interviews were used to explore physical activity motivation and benefits with a sample of highly active people with multiple sclerosis (n = 15). Disability level ranged from not disabled to wheelchair bound with the majority of participants reporting minimal impact from multiple sclerosis. Survey data were collected using a number of open-ended questions along with measures of self-efficacy, self-determined motivation, physical activity, and quality of life. Additionally, eight individuals participated in semistructured telephone interviews focused on (a) motivation and strategies used to maintain physical activity and (b) the benefits and impact of physical activity in their lives. The main findings were consistent with Self-Determination Theory; participants described feelings of accomplishment and competence in both their physical activity and daily life, as well as a sense of independence and autonomy. Similarly, all participants cited benefits, and the main themes were enhanced satisfaction with life and an overall positive outlook on life. Results provide insight into the role of physical activity in a highly active sample and have implications for professionals working in physical activity settings with the multiple sclerosis population. Interventions aimed at increasing long-term physical activity adherence should focus on increasing autonomy and competence for physical activity in the individual and promoting potential increased quality of life outcomes from physical activity participation. Implications for Rehabilitation Multiple sclerosis is a chronic

  9. New accounting information system: An application for a basic social benefit in Spain

    2018-01-01

    Full Text Available Accounting information on social benefits is included, in accordance with the scope of its management, in the general Social Security budget. The information contained in the budget may be relevant, but it is likely to be insufficient to enable comparisons to be made with an entity's financial statements for previous periods and with the financial statements of other entities. Thus, IPSAS 1 proposes the presentation of additional information. On the basis of the New Public Management theory, this paper proposes an aggregate accounting model for accounting expenditure as a multi-annual information system which complements and expands information on a potential basic social benefit. This system reports in detail on the trends in the items that fund it, with the aim of achieving maximum transparency and accountability in public administrations by ensuring timely provision of quality information.

  10. Basics of Laser Physics For Students of Science and Engineering

    CERN Document Server

    Renk, Karl F

    2012-01-01

    Basics of Laser Physics provides an introductory presentation of the field of all types of lasers. It contains a general description of the laser, a theoretical treatment and a characterization of its operation as it deals with gas, solid state, free-electron and semiconductor lasers and, furthermore, with a few laser related topics. The different subjects are connected to each other by the central principle of the laser, namely, that it is a self-oscillating system. Special emphasis is put on a uniform treatment of gas and solid-state lasers, on the one hand, and semiconductor lasers, on the other hand. The discussions and the treatment of equations are presented in a way that a reader can immediately follow. The book addresses undergraduate and graduate students of science and engineering. Not only should it enable instructors to prepare their lectures, but it can be helpful to students for preparing for an examination.

  11. W, F, and I : Three quantities basic to radiation physics

    International Nuclear Information System (INIS)

    Inokuti, M.

    1998-01-01

    The W value is an index of the mean number of ions produced in a gas subjected to ionizing radiation. Formally, it is defined as the radiation energy absorbed (usually expressed in units of eV) ''per ion pair of either sign produced'', or, in a simpler language, ''per electron liberated''. The basic knowledge up to 1961 is eloquently articulated in a classic essay by Platzman [1], which Professor Doke loves to cite. The theme of Platzman was to explain from the point of view of basic physics the magnitude and characteristics of the ratio W/I, where I is the (first) ionization threshold energy. In summary, major characteristics are as follows. (1) The W value for a given gas depends weakly on the properties of the radiation such as the mass and charge of particles or initial energies (provided they are sufficiently high). This makes the ionization measurement useful as a method of dosimetry, viz., the determination of the absorbed energy. (2) The ratio W/I is always greater than unity because a part of the absorbed energy must be used in nonionizing events such as discrete excitation or molecular dissociation into neutral fragments and also in producing subexcitation electrons, viz., electrons with kinetic energies too low to cause electronic excitation or ionization [2]. (3) The ratio W/I is 1.7-1.8 for rare gases, and 2.1-2.6 for gases of common molecules (depending on the electronic structure, going from ''hard'' to ''soft''). Calculation of the W value is possible from three approaches: (i) the energy balance of Platzman, heuristic for general understanding and appropriate for an estimate; (ii) the Fowler equation [3] for the direct evaluation of the mean number of ions produced; and (iii) the method of Spencer and Fano [4] through the degradation spectra (or the track length distributions) of charged particles, most importantly of electrons, present in the medium. The Fowler method is good for obtaining the mean number of ions or excited states resulting from

  12. [Psychological benefits of physical activity for optimal mental health].

    Science.gov (United States)

    Poirel, Emmanuel

    Mental health is a worldwide public health concern, as can be seen from the WHO's comprehensive mental health action plan 2013-2020 which was adopted by the 66th World Health Assembly. According to the Mental health commission of Canada (2012), one in five Canadians will personally experience a mental illness in their lifetime, and the WHO shows that mental illness represents the second most prevalent risk of morbidity after heart disease. Physical activity certainly provides an answer to this problem. Physical activity has been shown to improve physical health but it is also one of the most natural and accessible means to improve mental health. The aim of the present article is to propose a biopsychosocial model on the basis of a literature review on the psychological benefits of physical activity. In view of the findings we assume that physical activity increases mental well-being and optimal mental health as opposed to poor mental health. Hence, physical activity provides a state of well-being that enables individuals to realize their own potential, and that helps to cope with the normal stresses of life or adversity. The model certainly opens the way for research and new hypothesis, but it also aims at the promotion of the benefits of physical activity on psychological well-being for optimal mental health.

  13. The economic benefits of reducing physical inactivity: an Australian example

    2011-09-01

    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

    Increasing evidence supports the multiple benefits to physical, psychological and emotional wellbeing of green physical activity, a topic of increasing interest in the past decade. Research has revealed a synergistic benefit of green physical activity, which includes all aspects of exercise and physical activity in the presence of nature. Our theoretical analysis suggests there are three distinct levels of engagement in green physical activity, with each level reported to have a positive effect on human behaviours. However, the extent to which each level of green physical activity benefits health and wellbeing is assumed to differ, requiring confirmation in future research. This elucidation of understanding is needed because previous literature has tended to focus on recording empirical evidence rather than developing a sound theoretical framework to understand green physical activity effects. Here we propose an ecological dynamics rationale to explain how and why green physical activity might influence health and wellbeing of different population groups. This framework suggests a number of unexplored, interacting constraints related to types of environment and population groups, which shape reported levels of benefit of green physical activity. Further analysis is needed to clarify the explicit relationship between green physical activity and health and wellbeing, including levels of engagement, types of environmental constraints, levels of physical activity, adventure effects, skill effects and sampling of different populations.

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

    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.

    While benefits of workplace physical exercise on physical health is well known, little is known about the psychosocial effects of such initiatives. This study evaluates the effect of workplace versus home-based physical exercise on psychosocial factors among healthcare workers. A total of 200 female healthcare workers (Age: 42.0, BMI: 24.1) from 18 departments at three hospitals were cluster-randomized to 10 weeks of: 1) home-based physical exercise (HOME) performed alone during leisure time for 10 min 5 days per week or 2) workplace physical exercise (WORK) performed in groups during working hours for 10 min 5 days per week and up to 5 group-based coaching sessions on motivation for regular physical exercise. Vitality and mental health (SF-36, scale 0-100), psychosocial work environment (COPSOQ, scale 0-100), work- and leisure disability (DASH, 0-100), control- (Bournemouth, scale 0-10) and concern about pain (Pain Catastrophizing Scale, scale 0-10) were assessed at baseline and at 10-week follow-up. Vitality as well as control and concern about pain improved more following WORK than HOME (all p health remained unchanged. Between-group differences at follow-up (WORK vs. HOME) were 7 [95% confidence interval (95% CI) 3 to 10] for vitality, -0.8 [95% CI -1.3 to -0.3] for control of pain and -0.9 [95% CI -1.4 to -0.5] for concern about pain, respectively. Performing physical exercise together with colleagues during working hours was more effective than home-based exercise in improving vitality and concern and control of pain among healthcare workers. These benefits occurred in spite of increased work pace. NCT01921764 at ClinicalTrials.gov . Registered 10 August 2013.

    Epilepsy is a common disease found in 2% of the population, affecting people from all ages. Unfortunately, persons with epilepsy have previously been discouraged from participation in physical activity and sports for fear of inducing seizures or increasing seizure frequency. Despite a shift in medical recommendations toward encouraging rather than restricting participation, the stigma remains and persons with epilepsy continue to be less active than the general population. For this purpose, clinical and experimental studies have analysed the effect of physical exercise on epilepsy. Although there are rare cases of exercise-induced seizures, studies have shown that physical activity can decrease seizure frequency, as well as lead to improved cardiovascular and psychological health in people with epilepsy. The majority of physical activities or sports are safe for people with epilepsy to participate in with special attention to adequate seizure control, close monitoring of medications, and preparation of family or trainers. The evidence shows that patients with good seizure control can participate in both contact and non-contact sports without harmfully affecting seizure frequency. This article reviews the risks and benefits of physical activity in people with epilepsy, discusses sports in which persons with epilepsy may participate, and describes the positive effect of physical exercise in experimental models of epilepsy.

    2013-01-01

    This study examined whether perceived barriers, benefits, and motives for physical activity differed based on allocation to 2 different types of primary-care activity-prescription programs (pedometer-based vs. time-based Green Prescription). Eighty participants from the Healthy Steps study completed a questionnaire that assessed their perceived barriers, benefits, and motives for physical activity. Factor analysis was carried out to identify common themes of barriers, benefits, and motives for physical activity. Factor scores were then used to explore between-groups differences for perceived barriers, benefits, and motives based on group allocation and demographic variables. No significant differences were found in factor scores based on allocation. Demographic variables relating to the existence of chronic health conditions, weight status, and older age were found to significantly influence perceived barriers, benefits, and motives for physical activity. Findings suggest that the addition of a pedometer to the standard Green Prescription does not appear to increase perceived motives or benefits or decrease perceived barriers for physical activity in low-active older adults.

    2009-04-01

    The purpose of the article was to examine the physical activity perceptions and behaviors of older adults who were active participants in a statewide senior games (i.e., North Carolina Senior Games; NCSG) program with its focus on year-round involvement through activities in local communities. A random sample of 440 older adults (55 years and older) completed a questionnaire in 2006 about their participation in community-based senior games. A uniqueness of this study is its focus on active older adults, which provides insight into how to maintain physical involvement. Older adults who were most active perceived the most benefits from senior games but did not necessarily have the fewest constraints. This study of NCSG as an organization designed to promote healthy living in communities offered an example of how a social-ecological framework aimed at health promotion can be applied.

    The public is aware that nuclear reactors can be made to operate, so this paper treats reactor lattice and core physics as briefly as possible before proceeding to the physical principles of reactor control which currently seems of more public concern. First the role of delayed fission neutrons in slowing down the exponential divergence of a super-critical reactor is outlined. Next the physical basis of the various components of the power coefficient of reactivity is explained together with the methods of adjusting this coefficient toward the desired value. Finally, longer-term reactivity effects are discussed with emphasis on the several effects of Xe-135 'poison' on reactor design and operation. (author)

  8. Contributions of basic nuclear physics to the nuclear waste management

    2002-04-01

    Nuclear fission is presently a contested method of electricity production. The issue of nuclear waste management stands out among the reasons why. On the other hand, the nuclear industry has demonstrated its capacity to reliably generate cheap electricity while producing negligible amounts of greenhouse gases. These assets explain why this form of energy is still considered among the options for the long term production of electricity at least in developed countries. However, in order to tackle the still not adequately answered question of the waste, new schemes may have to be considered. Among those which have been advanced recently, the less polluting cycles such as those based on Thorium rather than Uranium and/or the transmutation of the minor actinides and some long lived fission products of the present cycle have been actively investigated. In both cases, it turns that the basic knowledge underlying these methods is either missing or incomplete. This situation opens a window of opportunity for useful contributions from basic nuclear physicists. This article describes some of them and presents the ongoing activities as well as some of the projects put forth for the short or medium term. .

    Nuclear magnetic resonance (NMR) is a remarkable phenomenon which involves the exchange of very weak radio frequency radiation between atomic nuclei and a sensitive detecting apparatus. It was originally regarded as a rather esoteric effect of great theoretical interest, but has since proved to have an amazing range of applications over many scientific disciplines, including nuclear physics, solid state physics, all branches of chemistry, biochemistry, physiology and most recently in medical diagnosis. In this Discourse the principles of NMR and trace briefly the history of its applications are examined and illustrated. Headings are: early history; nuclear resonance; relaxation time; the chemical shift; spin-spin coupling (NMR spectra); chemical shifts in biological tissue; NMR imaging; conclusions. (author)

    The divertor of a tokamak reactor will have to satisfy a number of critical constraints, the first of which is that the divertor targets not fail due to excessive heating or sputter-erosion. This paramount constraint of target survival defines the operating window for the principal plasma properties at the divertor target, the density n t and temperature, T t. In particular T et constitute, in effect, ‘code-experiments’ that—just as for actual experiments—can benefit from interpretation in terms of simple conceptual frameworks. 2 Point Model Formatting, 2PMF, of edge code output can provide such a conceptual framework. Methods of applying 2PMF are illustrated here with some examples.

  19. Ultra-high energy physics and standard basic principles

    2014-04-01

    Full Text Available It has not yet been elucidated whether the observed flux suppression for ultra-high energy cosmic rays (UHECR at energies above ≃ 4 x 1019 eV is a signature of the Greisen-Zatsepin-Kuzmin (GZK cutoff or a consequence of other phenomena. In both cases, violations of the standard fundamental principles of Physics can be present and play a significant role. They can in particular modify cosmic-ray interactions, propagation or acceleration at very high energy. Thus, in a long-term program, UHECR data can hopefully be used to test relativity, quantum mechanics, energy and momentum conservation, vacuum properties... as well as the elementariness of standard particles. Data on cosmic rays at energies ≃ 1020 eV may also be sensitive to new physics generated well beyond Planck scale. A typical example is provided by the search for possible signatures of a Lorentz symmetry violation (LSV associated to a privileged local reference frame (the "vacuum rest frame", VRF. If a VRF exists, the internal structure of standard particles at ultra-high energy can undergo substantial modifications. Similarly, the conventional particle symmetries may cease to be valid at such energies instead of heading to a grand unification and the structure of vacuum may no longer be governed by standard quantum field theory. Then, the question whether the notion of Planck scale still makes sense clearly becomes relevant and the very grounds of Cosmology can undergo essential modifications. UHECR studies naturally interact with the interpretation of WMAP and Planck observations. Recent Planck data analyses tend to confirm the possible existence of a privileged space direction. If the observed phenomenon turns out to be a signature of the spinorial space-time (SST we suggested in 1996-97, then conventional Particle Physics may correspond to the local properties of standard matter at low enough energy and large enough distances. This would clearly strengthen the cosmological

  8. Scholar-activating teaching materials for quantum physics. Pt. 2. Basic facts of quantum physics and heuristic methods

    International Nuclear Information System (INIS)

    Huebel, Horst

    2010-01-01

    Traditionally in the center of interest on quantum physics referring to schools the question lies, whether electrons and photons are now particles or waves, a question, which is often characterized by the phrase ''wave-particle dualism'', which notoriously not exists in its original meaning. Against that by the author - basing on important preparatory works of Kueblbeck and Mueller - a new concept for the treatment of quantum physics for the school was proposed, which puts ''basic facts'' in the foreground, comparable with the Kueblbeck-Mueller ''characteristic features''. The ''basic facts'' are similar to axioms of quantum physics, by means of which a large number of experiments and phenomena can be ''explained'' at least qualitatively - in a heuristic way -. Instead of the so-called ''wave-particle dualism'' here uncertainty and complementarity are put in the foreground. The new concept is in the Internet under http://www.forphys.de extensively presented with many further materials. In the partial volumes of this publication manifold and carefully elaborated teaching materials are presented, by means of which scholars can get themselves the partial set of quantum physics referring to schools by different methods like learn at stations, short referates, Internet research, group puzzle, the query-sheet or the card-index method etc. In the present 2. part materials for the ''basic facts'' of quantum physics are prepared, by which also modern experiments can be interpreted. Here deals it with the getting of knowledge and application of the ''basic Facts''. This pursues also by real scholar experiments, simulations and analogy tests. The scholars obtain so more simply than generally a deeper insight in quantum physics.

    Methadone-maintained persons are at increased risk for many physical and mental health disorders compared to the general population. Increased physical activity could offset these risks. We assessed physical activity level, and perceived benefits and barriers to exercise in a group of 305 methadone-maintained smokers. Mean participant age was 39.9 years, 50.2% were male, 79.7% were non-Hispanic White, and mean body mass index was 29.8. Nearly 45% endorsed fair or poor physical health. Although participants perceived many benefits of exercise and few barriers, only 38% of participants met weekly recommendations for physical activity, and nearly 25% reported no physical activity. Those who met recommended guidelines were significantly more likely to endorse relapse prevention as a benefit of exercise. Motivating MMT patients to increase physical activity could have important physical, mental health, and drug treatment benefits. Copyright © 2013 Elsevier Inc. All rights reserved.

    This study investigated whether the positive behavioral and anthropometric outcomes of a pedometer-based physical activity 8-week challenge were maintained 6 months after the end of the program. It further investigated the motivational profile of those who maintained their physical activity levels in the months following the end of the program and of those who did not. Hospital employees from a university-affiliated multisite health care center in Canada participated using a questionnaire. Of the 235 participants who completed the 8-week challenge, 157 questionnaires were returned 6 months later. Paired-samples t tests were conducted between the baseline and follow-up scores as well as between the postprogram and follow-up scores to detect significant differences between the measurement points. This study shows that the pedometer-based physical activity helped hospital employees maintain a high level of physical activity as well as maintain a healthy body mass index after 6 months. The results demonstrated that during maintenance the high physical activity group obtained higher scores for identified regulation and intrinsic regulation compared with the other groups. The results of the study revealed that identified and intrinsic regulations are important contributors to maintaining physical activity among hospital employees.

    2018-05-01

    The introduction of electric circuit simulation software for undergraduate students in a general physics course is proposed in order to contribute to the constructive learning of electric circuit theory. This work focuses on the lab exercises based on dc, transient and ac analysis in electric circuits found in introductory physics courses, and shows how students can use the simulation software to do simple activities associated with a lab exercise itself and with related topics. By introducing electric circuit simulation programs in a general physics course as a brief activitiy complementing lab exercise, students develop basic skills in using simulation software, improve their knowledge on the topology of electric circuits and perceive that the technology contributes to their learning, all without reducing the time spent on the actual content of the course.

    Penedo, Frank J; Dahn, Jason R

    2005-03-01

    This review highlights recent work evaluating the relationship between exercise, physical activity and physical and mental health. Both cross-sectional and longitudinal studies, as well as randomized clinical trials, are included. Special attention is given to physical conditions, including obesity, cancer, cardiovascular disease and sexual dysfunction. Furthermore, studies relating physical activity to depression and other mood states are reviewed. The studies include diverse ethnic populations, including men and women, as well as several age groups (e.g. adolescents, middle-aged and older adults). Results of the studies continue to support a growing literature suggesting that exercise, physical activity and physical-activity interventions have beneficial effects across several physical and mental-health outcomes. Generally, participants engaging in regular physical activity display more desirable health outcomes across a variety of physical conditions. Similarly, participants in randomized clinical trials of physical-activity interventions show better health outcomes, including better general and health-related quality of life, better functional capacity and better mood states. The studies have several implications for clinical practice and research. Most work suggests that exercise and physical activity are associated with better quality of life and health outcomes. Therefore, assessment and promotion of exercise and physical activity may be beneficial in achieving desired benefits across several populations. Several limitations were noted, particularly in research involving randomized clinical trials. These trials tend to involve limited sample sizes with short follow-up periods, thus limiting the clinical implications of the benefits associated with physical activity.

    The weakness of scientific ability of students in college has been being a concern in this case, especially in terms of laboratory activities to support Laboratory Based Education. Scientific ability is a basic ability that must be dominated by students in basic physics lecturing process as a part of scientific method. This research aims to explore the indicators emergence of the scientific ability of students in Chemistry Education of Study Program, Faculty of Teaching and Education University of Palangka Raya through Inquiry Based Learning in basic physics courses. This research is a quantitative research by using descriptive method (descriptive-quantitative). Students are divided into three categories of group those are excellent group, low group, and heterogeneous group. The result shows that the excellent group and low group have same case that were occured decreasing in the percentage of achievement of scientific ability, while in heterogeneous group was increased. The differentiation of these results are caused by enthusiastic level of students in every group that can be seen in tables of scientific ability achievement aspects. By the results of this research, hoping in the future can be a references for further research about innovative learning strategies and models that can improve scientific ability and scientific reasoning especially for science teacher candidates.

  12. Geographic-didactical games as interactive tools to test and improve student's basic knowledge in Physical Geography

    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

    Objective To study dancers’ perceptions of the physical, cognitive, affective, and social benefits of partnered dancing. Method 225 dancers (71% female) were recruited through a community ballroom dance center and completed an online survey designed to measure their perceptions of the physical, cognitive, affective, and social benefits of modern, partnered dance styles (swing, Lindy Hop, and ballroom dancing). Subgroups were formed for analyses. For one set of analyses, groups based on length of dance participation were formed: experienced (dancing for more than 2 years) or novice (dancing for less than a year) dancers. For another set of analyses, groups based on frequency of dance practice were formed: committed (dancing at least one or more times per week) or occasional (dancing two or fewer times per month). Results The majority of participants reported perceived benefits in physical fitness, cognition, affect, and social functioning. Experienced dancers reported significantly greater self-perceived physical, social, and cognitive benefits than novice dancers. Committed dancers were more likely than occasional dancers to report improvements in physical fitness, U = 6,942, z = 2.38, r = .16, p dance participation significantly predicted perceived physical benefits [X2 (1,6) = 35.463, p dance styles is associated with perceived improvements in physical fitness, cognitive functioning, social functioning, mood, and self-confidence, and that perceived benefits may increase as individuals dance more frequently and over longer periods of time.

    To determine the age- and sex-specific differences of physical fitness performances and Body Mass Index (BMI) in basic training and the operational Army. Cross-sectional Study. This secondary analysis utilizes retrospective surveys of U.S. Army Soldiers in Basic Combat Training (BCT) and operational units to compare physical performances between men and women as measured by the Army Physical Readiness Test (APFT). An ANOVA was used to compare mean differences in APFT results and BMI within sex-specific populations. A post hoc Tukey test identified specific mean differences. Adjusting for age, an ANCOVA was used to compare sex and occupation (infantry and non-infantry) differences in APFT results. Surveyed populations consisted of 2216 BCT Soldiers (1573 men and 643 women) and 5515 Operational Soldiers (4987 men and 528 women). Male and female operational Soldiers had greater muscular performance (79%-125% higher APFT push-ups, 66%-85% higher APFT sit-ups) and cardiorespiratory performance (22%-24% faster APFT 2-mile run times) than BCT Soldiers. Male BCT and operational Soldiers outperform their female counterparts on tests of muscular and cardiorespiratory endurance. Sex differences in physical performances attenuated among female Soldiers in operational units compared to BCT. Among male operational Soldiers, infantry Soldiers exhibited greater cardiorespiratory and muscular performance than non-infantry Soldiers. Higher BMI was associated with higher age groups, except for female BCT Soldiers. Gaps in cardiorespiratory and muscular performances between men and women should be addressed through targeted physical training programs that aim to minimize physiological differences.

    Summary Objectives to describe yoga practice and health characteristics of individuals who practice yoga, and to explore their beliefs regarding the effects of their yoga practice on their health. Design a cross-sectional design with anonymous online surveys Setting 4307 randomly selected individuals from 15 US Iyengar yoga studios (n = 18,160), representing 41 states; 1087 individuals responded, with 1045 (24.3%) surveys completed. Outcome Measures Freiberg Mindfulness Inventory, Mental Health Continuum (subjective well-being), Multi-factor Screener (diet), PROMIS sleep disturbance, fatigue, and social support, International Physical Activity Questionnaire. Results Age: 19 to 87 years (M = 51.7 ± 11.7), 84.2% female, 89.2% white, 87.4% well educated (≥ bachelor’s degree). Mean years of yoga practice = 11.4 (± 7.5). BMI = 12.1–49.4 (M = 23.1 ± 3.9). Levels of obesity (4.9%), smoking (2%), and fruit and vegetable consumption (M = 6.1 ± 1.1) were favorable compared to national norms. 60% reported at least one chronic/serious health condition, yet most reported very good (46.3%) or excellent (38.8%) general health. Despite high levels of depression (24.8 %), nearly all were moderately mentally healthy (55.2%) or flourishing (43.8%). Participants agreed yoga improved: energy (84.5%), happiness (86.5%), social relationships (67%), sleep (68.5%), and weight (57.3%), and beliefs did not differ substantially according to race or gender. The more they practiced yoga, whether in years or in amount of class or home practice, the higher their odds of believing yoga improved their health. Conclusions Individuals who practice yoga are not free of health concerns, but most believe their health improved because of yoga. Yoga might be beneficial for a number of populations including elderly women and those with chronic health conditions. PMID:23876562

    1999-04-01

    Several aspects of the manifestation of the causality principle in LQP (local quantum physics) are reviewed or presented. Particular emphasis is given to those properties which are typical for LQP in the sense that they do go beyond the structure of general quantum theory and even escape the Lagrangian quantization methods of standard QFT. The most remarkable are those relating causality to the modular Tomita-Takesaki theory, since they bring in the basic concepts of antiparticles, charge superselections as well as internal and external (geometric and hidden) symmetries.

    Andreas Holtermann

    Full Text Available PURPOSE: To investigate if persons with high physical activity at work have the same benefits from leisure time physical activity as persons with sedentary work. METHODS: In the Copenhagen City Heart Study, a prospective cohort of 7,411 males and 8,916 females aged 25-66 years without known cardiovascular disease at entry in 1976-78, 1981-83, 1991-94, or 2001-03, the authors analyzed with sex-stratified multivariate Cox proportional hazards regression the association between leisure time physical activity and cardiovascular and all-cause mortality among individuals with different levels of occupational physical activity. RESULTS: During a median follow-up of 22.4 years, 4,003 individuals died from cardiovascular disease and 8,935 from all-causes. Irrespective of level of occupational physical activity, a consistently lower risk with increasing leisure time physical activity was found for both cardiovascular and all-cause mortality among both men and women. Compared to low leisure time physical activity, the survival benefit ranged from 1.5-3.6 years for moderate and 2.6-4.7 years for high leisure time physical activity among the different levels of occupational physical activity. CONCLUSION: Public campaigns and initiatives for increasing physical activity in the working population should target everybody, irrespective of physical activity at work.

    To investigate if persons with high physical activity at work have the same benefits from leisure time physical activity as persons with sedentary work. In the Copenhagen City Heart Study, a prospective cohort of 7,411 males and 8,916 females aged 25-66 years without known cardiovascular disease at entry in 1976-78, 1981-83, 1991-94, or 2001-03, the authors analyzed with sex-stratified multivariate Cox proportional hazards regression the association between leisure time physical activity and cardiovascular and all-cause mortality among individuals with different levels of occupational physical activity. During a median follow-up of 22.4 years, 4,003 individuals died from cardiovascular disease and 8,935 from all-causes. Irrespective of level of occupational physical activity, a consistently lower risk with increasing leisure time physical activity was found for both cardiovascular and all-cause mortality among both men and women. Compared to low leisure time physical activity, the survival benefit ranged from 1.5-3.6 years for moderate and 2.6-4.7 years for high leisure time physical activity among the different levels of occupational physical activity.

    The purpose of this study was to examine the determinants of benefits and barriers and their relationship with physical activity (PA) among predominantly Latino middle school students. Data were collected in a cross-sectional survey of 4,773 seventh-grade students recruited from a large, urban school district in Los Angeles. Hierarchical logistic regression models were used to assess determinants of benefits and barriers as well as their association with self-reported PA. Differences in benefits and barriers were observed by gender, ethnicity, and body size. Barriers were negatively correlated with all three PA outcomes while benefits were positively associated with exercising at least 60 min daily. A deeper understanding of benefits and barriers can facilitate the development of interventions and collaborative efforts among physical education teachers, school nurses, and administrators to implement comprehensive approaches that encourage students' participation in PA inside and outside of the classroom.

    Full Text Available The National Curriculum Statement for matric physical science places strong emphasis on the development of critical thinking and reasoning abilities of pupils. The successful implementation of this curriculum therefore requires teachers who are competent in the cognitive (intellectual skills and strategies needed for learning science effectively. Testing of teachers’ competence in this aspect is therefore important. I therefore analysed teachers’ answers to questions that were carefully designed to test competence in some basic intellectual strategies that are important for problem solving in physical science courses. A total of 73 matric physical science teachers, from about 50 Dinaledi schools in the North West and KwaZulu-Natal provinces in South Africa, were tested in five intellectual strategies: clear representation of problems, identifying and focusing on the goal, identification and use of relevant principles, use of equations for deductions and proceeding step-by-step with the solution. The teachers’ competence was poor in all the intellectual strategies tested. About 60% (the average performance in all 13 questions used for testing of teachers tested were unable to solve the questions correctly. An important objective of the curriculum is the development of critical thinking, scientific reasoning and strategies of pupils. This study shows that the achievement of this objective will be seriously handicapped because of the lack of competence of many teachers in intellectual strategies. There is therefore a need to train teachers in order to increase their competence in this aspect.

    According to the literature, 40% of injuries affecting school-age children are sports related. The role of physical education students, as future teachers, seems to be of high importance in terms of protecting children's safety during sports classes. The aim is to evaluate the level of basic life support (BLS) knowledge and skills in physical education students instructed with the use of different methods. Second-year physical education students (n=104, M age=20±0.6 years) were randomly assigned to three groups: experimental 1 (E1), experimental 2 (E2), and control (C). Group E1 students participated in a 2-hour BLS course based on computer-assisted presentations. Group E2 trainees practiced BLS algorithm in pairs during a 2-hour course. No manikins were used in both intervention groups. Students of Group C were asked to learn BLS algorithm on their own. All groups fulfilled a 10-question multiple-choice test on BLS at the beginning and the end of the experiment. After completing the course participants performed BLS on a manikin. The results of knowledge test were not significant before an experiment but differed essentially among the groups afterward (analysis of variance contrast analysis, peducation students. Moreover, permanent consultation on instructional methods with emergency medicine experts is recommended for university teachers.

  12. Healthy hearts--and the universal benefits of being physically active: physical activity and health.

    Science.gov (United States)

    Blair, Steven N; Morris, Jeremy N

    2009-04-01

    Although ancient thinkers suggested that physical activity is good for health, systematic research on the topic did not begin until the middle of the 20th century. Early reports showed that individuals in active occupations had lower rates of heart disease than individuals in sedentary occupations. Investigators then began to evaluate leisure-time physical activity and health and found similar results. Later research used objective measures of cardiorespiratory fitness as the exposure, and found even stronger associations with health outcomes. Recent research has extended the earlier findings on activity or fitness and heart disease to a wide variety of health outcomes. We now know that regular physical activity of 150 minutes/week of moderate intensity physical activity reduces the risk of numerous chronic diseases, preserves health and function (both physical and mental) into old age, and extends longevity. The current challenge is to develop programs and interventions to promote physical activity for all in our increasingly sedentary societies.

  13. Basic physical phenomena, neutron production and scaling of the dense plasma focus

    International Nuclear Information System (INIS)

    Kaeppeler, H.J.

    This paper presents an attempt at establishing a model theory for the dense plasma focus in order to present a consistent interpretation of the basic physical phenomena leading to neutron production from both acceleration and thermal processes. To achieve this, the temporal history of the focus is divided into the compression of the plasma sheath, a qiescent and very dense phase with ensuing expansion, and an instable phase where the focus plasma is disrupted by instabilities. Finally, the decay of density, velocity and thermal fields is considered. Under the assumption that Io 2 /sigmaoRo 2 = const and to/Tc = const, scaling laws for plasma focus devices are derived. It is shown that while generally the neutron yield scales with the fourth power of maximum current, neutron production from thermal processes becomes increasingly important for large devices, while in the small devices neutron production from acceleration processes is by far predominant.

    TORPEX is a basic plasma physics toroidal device located at the CRPP-EPFL in Lausanne. In TORPEX, a vertical magnetic field superposed on a toroidal field creates helicoidal field lines with both ends terminating on the torus vessel. We review recent advances in the understanding and control of electrostatic interchange turbulence, associated structures and their effect on suprathermal ions. These advances are obtained using high-resolution diagnostics of plasma parameters and wave fields throughout the whole device cross-section, fluid models and numerical simulations. Furthermore, we discuss future developments including the possibility of generating closed field line configurations with rotational transform using an internal toroidal wire carrying a current. This system will also allow the study of innovative fusion-relevant configurations, such as the snowflake divertor.

  15. Applications of nanosecond, kilojoule lasers to the basic physics of waves in plasmas

    International Nuclear Information System (INIS)

    Drake, R.P.

    1992-01-01

    Plasmas can sustain many normal modes of oscillation (waves), including both electromagnetic and electrostatic modes. These waves can interact by a wide variety of linear and nonlinear mechanisms, including mode coupling, mixing, and instabilities. Furthermore, such mechanisms compete, so that a given wave might be absorbed, might mode convert, or might decay by one of several instabilities, depending upon the specific circumstances in which it is produced. Moreover, such waves are important in many applications, including for example laser fusion, x-ray lasers, plasma accelerators, and ionospheric heating. Laser-produced plasmas can provide an effective medium for the studies of such waves and the related mechanisms. New opportunities will be made possible by the advent of comparatively inexpensive nanosecond, kilojoule lasers. One can now contemplate affordable experiments, not limited by programmatic constraints, that could study such the basic physics of the waves in such plasmas with unprecedented precision and in unprecedented detail

    Full Text Available The purpose of this study was to examine the benefits of physical exercise among secondary school students. Participants in the study were 251 students (120 boys and 131 girls attending three public secondary schools in the Hlanganani rural area of South Africa. A validated questionnaire was used to collect data. Results of this study indicated that students exercised to be with their friends, to be physically attractive and compete with others. The findings of this study have practical implications for promoting participation in physical activity among students in rural schools. In an effort to promote physical activity participation, schools should be provided with quality sports infrastructure and funding so that they can implement school sport programmes. Finally, the teaching of physical education should be emphasised in schools as it is the cornerstone for children’s involvement in physical activity.

    Recognizing that students benefit when they receive autonomy-supportive teaching, the current study tested the parallel hypothesis that teachers themselves would benefit from giving autonomy support. Twenty-seven elementary, middle, and high school physical education teachers (20 males, 7 females) were randomly assigned either to participate in an autonomy-supportive intervention program (experimental group) or to teach their physical education course with their existing style (control group) within a three-wave longitudinal research design. Manipulation checks showed that the intervention was successful, as students perceived and raters scored teachers in the experimental group as displaying a more autonomy-supportive and less controlling motivating style. In the main analyses, ANCOVA-based repeated-measures analyses showed large and consistent benefits for teachers in the experimental group, including greater teaching motivation (psychological need satisfaction, autonomous motivation, and intrinsic goals), teaching skill (teaching efficacy), and teaching well-being (vitality, job satisfaction, and lesser emotional and physical exhaustion). These findings show that giving autonomy support benefits teachers in much the same way that receiving it benefits their students.

    Opioid dependence is growing at an alarming rate in the United States, and opioid dependent patients have substantial medical, as well as psychiatric, conditions that impact their ability to work. This study evaluated the association between antisocial personality disorder (ASPD) and receipt of physical disability payments in methadone maintenance patients. Using data from 115 drug and alcohol abusing methadone maintained patients participating in two clinical trials, baseline characteristics of individuals receiving (n=22) and those not receiving (n=93) physical disability benefits were compared, and a logistic regression evaluated unique predictors of disability status. Both an ASPD diagnosis and severity of medical problems were significant predictors of disability receipt, ps<.05. After controlling for other variables that differed between groups, patients with ASPD were more than five times likelier to receive physical disability benefits than patients without ASPD (odds ratio=5.66; 95% confidence interval=1.58-20.28). These results demonstrate a role of ASPD in the receipt of disability benefits in substance abusers and suggest the need for greater understanding of the reasons for high rates of physical disability benefits in this population.

    Mating motivations can explain attractiveness benefits, but what proximate mechanisms might serve as efficient causes of these biases? There is growing evidence that visual cues of physical attractiveness capture attention and facilitate memory, enhancing salience in ways that could underlie, for example, preferring one job applicant over another. All of these effects beg deeper questions about the meaning of attractiveness.

    This study showed that about a half of the exercise-induced gain in dynamic balance and bone strength was maintained one year after cessation of the supervised high-intensity training of home-dwelling elderly women. However, to maintain exercise-induced gains in lower limb muscle force and physical functioning, continued training seems necessary. Maintenance of exercise-induced benefits in physical functioning and bone structure was assessed one year after cessation of 12-month randomized controlled exercise intervention. Originally 149 healthy women 70-78 years of age participated in the 12-month exercise RCT and 120 (81%) of them completed the follow-up study. Self-rated physical functioning, dynamic balance, leg extensor force, and bone structure were assessed. During the intervention, exercise increased dynamic balance by 7% in the combination resistance and balance-jumping training group (COMB). At the follow-up, a 4% (95% CI: 1-8%) gain compared with the controls was still seen, while the exercise-induced isometric leg extension force and self-rated physical functioning benefits had disappeared. During the intervention, at least twice a week trained COMB subjects obtained a significant 2% benefit in tibial shaft bone strength index compared to the controls. A half of this benefit seemed to be maintained at the follow-up. Exercise-induced benefits in dynamic balance and rigidity in the tibial shaft may partly be maintained one year after cessation of a supervised 12-month multi-component training in initially healthy elderly women. However, to maintain the achieved gains in muscle force and physical functioning, continued training seems necessary.

    Frailty is a state of vulnerability associated with increased risks of fall, hospitalization, cognitive deficits, and psychological distress. Studies with healthy senior suggest that physical exercise can help improve cognition and quality of life. Whether frail older adults can show such benefits remains to be documented. A total of 83 participants aged 61-89 years were assigned to an exercise-training group (3 times a week for 12 weeks) or a control group (waiting list). Frailty was determined by a complete geriatric examination using specific criteria. Pre- and post-test measures assessed physical capacity, cognitive performance, and quality of life. Compared with controls, the intervention group showed significant improvement in physical capacity (functional capacities and physical endurance), cognitive performance (executive functions, processing speed, and working memory), and quality of life (global quality of life, leisure activities, physical capacity, social/family relationships, and physical health). Benefits were overall equivalent between frail and nonfrail participants. Physical exercise training leads to improved cognitive functioning and psychological well-being in frail older adults.

    The increase in aging populations has implications for the provision of health and social services. A preventative approach is taken to address this problem by examining a mechanism that can enhance physical health and reduce minor ailments. Participants in 10 focus groups discussed physical, psychological, and social benefits associated with human-dog interactions. Interaction between humans and dogs is a mechanism that can enhance the physical and psychological health of elderly citizens and promote a social support network between dog owners. In turn, dependence and impact on health and social services are alleviated. The social and community consequences of promoting dog ownership in the elderly are addressed, and it is concluded that the benefits of dog ownership should be promoted among the elderly and acknowledged by relevant agencies.

    To analyze attitudes and beliefs about movement and physical activity in people with low back pain (LBP) and compare these beliefs between people with acute and chronic LBP. Qualitative inductive analysis of data collected via face-to-face semistructured interviews. Interviews were audio-recorded and transcribed verbatim. Participants were purposively recruited from 1 region of New Zealand. Persons with LBP (N=23), consisting of individuals with acute LBP (3mo; n=11). Not applicable. Themes that emerged from participant interview transcripts using analysis based on Interpretative Description. Participants with acute and chronic LBP made judgments about physical activity and rest using the same conceptual model. Concerns about creating more pain, tissue damage, or impairment influenced the physical activity judgments of most participants with acute and chronic LBP. These perceived risks were balanced against the perceived benefits, the most important of which were psychological or social rather than physical. Judgments made by those with acute and chronic LBP were context dependent and influenced by the nature and duration of pain, the type of physical activity, the importance of the activity, and the participant's previous experience. Participants with acute pain who had not experienced back pain previously often expressed more uncertainty, whereas those with chronic LBP appeared to have developed cognitive rules that determined physical activity decisions. Exploring the perceived risks, benefits, and contextual factors that influence decisions about physical activity and rest may help clinicians to understand the behavior of patients with acute and chronic LBP. Clinicians may best support their patients to engage in physical activity by providing an informed assessment of risks and an explanation about the range of potential benefits.

    Current research suggests a role for biomedical knowledge in learning and retaining concepts related to medical diagnosis. However, learning may be influenced by other, non-biomedical knowledge. We explored this idea using an experimental design and examined the effects of causal knowledge on the learning, retention, and interpretation of medical information. Participants studied a handout about several respiratory disorders and how to interpret respiratory exam findings. The control group received the information in standard "textbook" format and the experimental group was presented with the same information as well as a causal explanation about how sound travels through lungs in both the normal and disease states. Comprehension and memory of the information was evaluated with a multiple-choice exam. Several questions that were not related to the causal knowledge served as control items. Questions related to the interpretation of physical exam findings served as the critical test items. The experimental group outperformed the control group on the critical test items, and our study shows that a causal explanation can improve a student's memory for interpreting clinical details. We suggest an expansion of which basic sciences are considered fundamental to medical education.

    Full Text Available This study presents the findings of a questionnaire-based investigation of knowledge about the relationship of physical activity to health among adolescent participants of a community-based physical activity intervention program in São Paulo, Brazil. Qualitative (inductive content analysis and quantitative methods were applied to examine the participants’ responses to two open-ended questions concerning the health benefits of physical activity and the educational goals of the intervention. More than 75% of all participants stated that health benefits (of some type are attained through participation in physical activity. More than 50% of participants reported that the goal of the intervention was to educate people about the importance of a healthy, active lifestyle. Adolescents understand the relationship of physical activity to health as reflected in their knowledge assessments; their lifestyle choices support these beliefs. These findings offer encouragement for the development and implementation of educationally oriented interventions aimed at providing physical activity information and programming.

    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.

    Full Text Available The objectives of this research were to study basic physical parameters of three agricultural residues that could be used for prediction of paddy drying kinetics using desiccants, to investigate a suitable methodfor moisture reduction of fresh paddy using 3 absorbents, and to modify the drying model of Inoue et al. for determining the evolution of moisture transfer during the drying period. Rice husk, sago palm rachis andcoconut husk were used as moisture desiccants in these experiments. From the results, it was concluded that the apparent density of all adsorbents was a linear function of moisture content whilst an equilibriummoisture content equation following Hendersonís model gave the best fit to the experimental results. From studying the relationship between moisture ratio and drying time under the condition of drying temperaturesof 30, 50 and 70oC, air flow rate of 1.6 m/s and initial moisture content of absorbents of 15, 20 and 27% dry-basis, it was shown that the moisture ratio decreased when drying time increased. In addition, thethin-layer desiccant drying equation following of the Page model can appropriately explain the evolution of moisture content of paddy over the drying time. The diffusion coefficient of all absorbents, which was in therange of 1x10-8 to 6x10-8 m2/h, was relatively dependent on drying temperature and inversely related to drying time. The diffusivity of coconut husk had the highest value compared to the other absorbents.The simulating modified mathematical model to determine drying kinetics of paddy using absorption technique and the simulated results had good relation to the experimental results for all adsorbents.

    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.

  15. Cognitive Deficit in Heart Failure and the Benefits of Aerobic Physical Activity

    Directory of Open Access Journals (Sweden)

    Maria Luíza de Medeiros Rêgo

    Full Text Available Abstract Heart Failure is a clinical syndrome prevalent throughout the world and a major contribution to mortality of cardiac patients in Brazil. In addition, this pathology is strongly related to cerebral dysfunction, with a high prevalence of cognitive impairment. Many mechanisms may be related to cognitive loss, such as cerebral hypoperfusion, atrophy and loss of gray matter of the brain, and dysfunction of the autonomic nervous system. The literature is clear regarding the benefits of aerobic physical activity in healthy populations in the modulation of the autonomic nervous system and in brain functions. Studies have shown that in the population of patients with heart failure, exercise is associated with an improvement in cognitive function, as well as in cardiac autonomic regulation. However, little emphasis has been given to the mechanisms by which aerobic physical activity can benefit brain functioning, the autonomic nervous system and result in better cognitive performance, particularly in patients with heart failure. Therefore, the present work presents the ways in which brain areas responsible for cognition also act in the modulation of the autonomic nervous system, and emphasizes its importance for the understanding of cognitive impairment in relation to the pathophysiology of heart failure. It is also described the way in which aerobic physical activity can promote benefits when it is integrated into the therapy, associated to a better prognosis of the clinical picture of these patients.

    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. © 2013 John Wiley & Sons Ltd.

    Full Text Available Purpose: Physical inactivity and depression are common among RA patients. Many variables are associated with different levels of mental health, including physical activity. Therefore, this study was designed to demonstrate the benefits of moderateintensity exercises on physical activity and mental health in RA patients compared to their sedentary counterparts. We also studied the correlation between physical activity and mental health variables, including depression. Methods: A total of 22 RA patients were recruited of both sexes and divided on the basis of training status into the following two groups: training group (2 men and 8 women aged 67±13 years (mean±SD and sedentary group (11 women and one man aged 67±9.8 years. The training group attended 45 minutes training sessions, three-five times a week for 6 months. All patients were taking currently treatment with at least one or more disease-modifying antirheumatic drugs (DMARDS or biologic agents. Blood samples were collected from all patients in order to assess serum C-reactive protein (CRP and erythrocyte sedimentation rate (ESR. The Disease Activity Score (DAS 28 was recorded in all subjects. Physical and mental health was assessed using the Medical Outcomes Study Short Form-36 Health Survey (SF-36. Results: Age, sex, disease duration, DAS28 and pain intensity (VAS were not significantly different between the groups (p>0.05. Physical and mental health outcomes significantly improved after 6 months of moderate aerobic training (p <0.05. Quality of life was better in the trained subjects, which showed a better life satisfaction and a higher level of physical and social function. In addition, we found that physical activity was negatively correlated with mental and emotional health especially in the training group (p=0.003. Conclusion: Our results indicate that higher levels of physical activity were associated with improved mental health. Moreover, physical and mental health outcomes

    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.

    This study compared perceived benefits and barriers to leisure-time physical activity during pregnancy among women who were insufficiently active or inactive before pregnancy. Eighty-two pregnant women completed questionnaires assessing leisure-time physical activity benefits/barriers, exercise self-efficacy, social support, depressed mood, pre-pregnancy and current physical activity and fatigue. Multivariable regression analyses identified factors associated with exercise benefits/barriers for the two pre-pregnancy leisure-time physical activity groups. Both pre-pregnancy leisure-time physical activity groups reported more benefits than barriers to exercise during pregnancy. Previously inactive women reported fewer perceived benefits and greater perceived barriers to leisure-time physical activity during pregnancy. Higher self-efficacy for exercise during pregnancy was significantly associated with greater benefits of leisure-time physical activity during pregnancy for both groups. Less family support for exercise and lower self-efficacy for exercise were significantly related to greater leisure-time physical activity barriers during pregnancy for previously inactive women. Lower self-efficacy for exercise, higher depressed mood scores, and younger age were associated with greater leisure-time physical activity barriers for active women. Findings suggest that the intensities of perceived leisure-time physical activity benefits and barriers during pregnancy differ for women, depending on their pre-pregnancy leisure-time physical activity status. Consideration of pre-pregnancy leisure-time physical activity status may thus be important when tailoring strategies to overcome barriers to promote initiation and maintenance of physical activity during pregnancy.

    This article assesses the socioeconomic effects of solar microgrids. The lack of access to electricity is a major obstacle to the socioeconomic development of more than a billion people. Off-grid solar technologies hold potential as an affordable and clean solution to satisfy basic electricity needs. We conducted a randomized field experiment in India to estimate the causal effect of off-grid solar power on electricity access and broader socioeconomic development of 1281 rural households. Within a year, electrification rates in the treatment group increased by 29 to 36 percentage points. Daily hours of access to electricity increased only by 0.99 to 1.42 hours, and the confidence intervals are wide. Kerosene expenditure on the black market decreased by 47 to 49 rupees per month. Despite these strong electrification and expenditure effects, we found no systematic evidence for changes in savings, spending, business creation, time spent working or studying, or other broader indicators of socioeconomic development.

    The Flow Tensor is an important physical quantity in High Energy Physics. The program used for the calculation of the Flow Tensor has been a complex menu-driven application, to allow the selection of various triggers for the studied reaction, of the number of traces in each studied event, of the momentum cut values for the resulting particles of fragments in each event, etc. We realised all that requests using a very modern and powerful tool: Visual Basic 3.0. This programming system allows the realisation of Windows-like programs and has numerous facilities: OLE (Object Linking and Embedding), the possibility to create professional graphics, to work with databases, to create and compile Windows-like help files. All these advantages make the effort to learn Visual Basic 3.0 worthwhile. (author)

    The African wild dog (Lycaon pictus) is an endangered exotic canid with less than 5500 animals remaining in the wild. Despite numerous strategies to conserve this species, numbers of free-living animals are in decline. It is a highly social species with a complex pack structure: separate male and female dominant hierarchies with, typically, participation of subdominant adults in the rearing of the dominant breeding pairs' pups. Basic reproductive knowledge is largely missing in this species, with only limited information available on the profile of reproductive hormones, based on non-invasive endocrine monitoring. The dominant or alpha male and female are reproductively active and the subdominants are generally reproductively suppressed. However, the occasional production of litters by subdominant females and evidence of multiple paternity within litters suggests that fertility of subordinates is not completely inhibited. In this respect, there are still considerable gaps in our knowledge about the mechanisms governing reproduction and reproductive suppression in African wild dogs, particularly the influence of dominance and pack structure on both male and female fertility. Given concerns over the long-term survival of this species, further research in this area is essential to provide valuable information for their captive breeding and conservation. Reproductive information can also be applied to the development of Assisted Reproductive Techniques for this species; the utility of which in African wild dog conservation is also discussed.

    We summarize much of the important science that could be learned at a North American low energy antiproton source. It is striking that there is such a diverse and multidisciplinary program that would be amenable to exploration. Spanning the range from high energy particle physics to nuclear physics, atomic physics, and condensed matter physics, the program promises to offer many new insights into these disparate branches of science. It is abundantly clear that the scientific case for rapidly proceeding towards such a capability in North America is both alluring and strong. 38 refs., 2 tabs

    The main propose of this study is the cross-cultural validation of the Basic Psychological Needs in Physical Education Scale among Portugal and Brazil samples, through the study of measurement model invariance. Participated in this study, two independent samples, one with 616 Portuguese students, of the 2nd and 3rd basic grade of public school, aged between 9 and 18 years old and another with 450 Brazilian students, from 1st, 2nd and 3rd middle grade of public and private school, aged between 14 and 18 years old. The results support the suitability of the model (three factors, each one with four items), showing an adequate fit to the data in each sample (Portugal: χ2 = 203.8, p = .001, df = 51, SRMR = .062, NNFI = .926, CFI = .943, RMSEA = .070, RMSEA 90% IC = .060-.080; Brazil: χ2 = 173.7, p = .001, df = 51, SRMR = .052, NNFI = .940, CFI = .954, RMSEA = .073, RMSEA 90% IC = .061-.085), as well valid cross-cultural invariance among Portuguese e Brazilian samples (∆CFI ≤ .01). Those findings allow us to conclude that scale can be used to measure the basic psychological needs in physical education in Portugal and in Brazil.

In the past, several interpretations of electrical resistivity results were unable to be delivered in a strong justification due to lack of appreciation of soil mechanics. Traditionally, interpreters will come out with different conclusion which commonly from qualitative point of view thus creating some uncertainty regarding the result reliability. Most engineers desire to apply any techniques in their project which are able to provide some clear justification with strong, reliable and meaningful results. In order to reduce the problem, this study presents the influence of basic physical properties of soil due to the electrical resistivity value under loose and dense condition. Two different conditions of soil embankment model were tested under electrical resistivity test and basic geotechnical test. It was found that the electrical resistivity value (ERV, ρ) was highly influenced by the variations of soil basic physical properties (BPP) with particular reference to moisture content (w), densities (ρbulk/dry), void ratio (e), porosity (η) and particle grain fraction (d) of soil. Strong relationship between ERV and BPP can be clearly presents such as ρ ∞ 1/w, ρ ∞ 1/ρbulk/dry, ρ ∞ e and ρ ∞ η. This study therefore contributes a means of ERV data interpretation using BPP in order to reduce ambiguity of ERV result and interpretation discussed among related persons such as geophysicist, engineers and geologist who applied these electrical resistivity techniques in subsurface profile assessment.

    The detection of physical inactivity in adults, using simple and useful tools is primary objective in both public health and in clinical settings, since this risk factor is one of the major causes of non-communicable disease in the world, and is very prevalent in developed societies such as in Spain. Two validated instruments are described that are simple and useful for detecting and/or monitoring physical inactivity in adults: (i)the international physical activity questionnaire in its short version, and (ii)the pedometer to measure the number of steps taken in a day. Increased levels of physical activity are important for the primary prevention of some chronic diseases (coronary heart disease, type2 diabetes, osteoporosis, colon cancer) and to improve the quality of life. Medical personnel must determine the motivation level and the availability of patients and their families to change their behavior towards physical activity. Moderate-intensity physical activities have hardly any contraindications and the risks are few. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

    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 Taking as theme the use of the history and philosophy of science as a strategy for the physics teaching in high school, we aim to investigate which topics of physics have already been the object of proposals and investigations in this sense. For this, we search for papers in the two most traditional Brazilian journals in the physics education area, the “Revista Brasileira de Ensino de Física” e the “Caderno Brasileiro de Ensino de Física”. We found papers that addressed the following topics: electric and magnetic fields, gravitation, relativity, astronomy, energy, electromagnetism, relations between force and motion, units of measurement, atmospheric pressure and vacuum. In this context, we point out the pertinence in expanding the list of topics that are the subject of studies of this type.

    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

    In this paper, we present a basic theory of fractional dynamics, i.e., the fractional conformal invariance of Mei symmetry, and find a new kind of conserved quantity led by fractional conformal invariance. For a dynamical system that can be transformed into fractional generalized Hamiltonian representation, we introduce a more general kind of single-parameter fractional infinitesimal transformation of Lie group, the definition and determining equation of fractional conformal invariance are given. And then, we reveal the fractional conformal invariance of Mei symmetry, and the necessary and sufficient condition whether the fractional conformal invariance would be the fractional Mei symmetry is found. In particular, we present the basic theory of fractional conformal invariance of Mei symmetry and it is found that, using the new approach, we can find a new kind of conserved quantity; as a special case, we find that an autonomous fractional generalized Hamiltonian system possesses more conserved quantities. Also, as the new method's applications, we, respectively, find the conserved quantities of a fractional general relativistic Buchduhl model and a fractional Duffing oscillator led by fractional conformal invariance of Mei symmetry.

    The long-term effects of leisure-time physical activity (LTPA) on job strain have not been assessed in a large prospective population-based cohort study. To examine the relationship between the LTPA and the prevalence of job strain. The participants were 861 full-time employees (406 men and 455 women), aged 24-39 years in 2001, from the ongoing Cardiovascular Risk in Young Finns Study. LTPA was assessed using a self-report questionnaire in 1992 and in 2001. The participants were grouped into four categories according to tertiles of LTPA index at two time points: persistently active, increasingly active, decreasingly active and persistently inactive. Job strain was measured in 2001 by indicators of job demands and job control. Baseline LTPA was inversely associated with job strain (P leisure may help young adults to cope with job strain. A long-term benefit of LTPA may play a role in the development of mental well-being.

  8. Effects of Physical Exercise on Cognitive Functioning and Wellbeing: Biological and Psychological Benefits

    Full Text Available Much evidence shows that physical exercise (PE is a strong gene modulator that induces structural and functional changes in the brain, determining enormous benefit on both cognitive functioning and wellbeing. PE is also a protective factor for neurodegeneration. However, it is unclear if such protection is granted through modifications to the biological mechanisms underlying neurodegeneration or through better compensation against attacks. This concise review addresses the biological and psychological positive effects of PE describing the results obtained on brain plasticity and epigenetic mechanisms in animal and human studies, in order to clarify how to maximize the positive effects of PE while avoiding negative consequences, as in the case of exercise addiction.

    Learning motivation revealed as a whole intrinsic factor that created, maintained and supported students to achieve the goal of learning. As the bigger motivation came with bigger success, motivation was considered as the main key to reach what students have planned. There were intrinsic and extrinsic factors that influence both the students and lecturers’ motivation. The factors in one hand, were essential to be defined by the lecturers in order to maintain and enhance the students’ enthusiasm. On the other hand, they also encouraged and thrilled the students to learn. The study aimed to expose and describe the motivational tendency and to knowledge and analyze learning obstacles faced by the students in basic physics class on students of prospective math teachers in FKIP Unswagati Cirebon. In addition, the study focused on the description of the six motivational components stated by Glyn and Koballa. The six were intrinsic motivation, extrinsic motivation, the relevance of studying physics for subjective purposes, willpower, self assessment and anxiety. Class responses were determined through questionnaire with four main indicators; the causes of being less popular subject, the cause of being disfavored subject, the description of the way the students draw the examination on basic physics subject and the academic background of the students. The results showed that 54% students stated that physics was disfavored because the subject was difficult to understand, 49% stated that the cause of being disfavored of the subject was because physics required complicated mathematics. Most of the students preferred to have game based activities that boosted thinking skill. According to the analysis of the students’ motivation, the findings revealed that the students’ had high level of anxiety in learning the subject. They mostly expressed their anxiety appeared from the material density and text book based assignments.

    The current absence of a disease-modifying treatment for Alzheimer's disease (AD) and vascular cognitive impairment and dementia (VCID) highlights the necessity for investigating the benefits of non-pharmacological approaches such as physical exercise (PE). Although evidence exists to support an association between regular PE and higher scores on cognitive function tests, and a slower rate of cognitive decline, there is no clear consensus on the underlying molecular mechanisms of the advantages of PE. This review seeks to summarize the positive effects of PE in human and animal studies while highlighting the vascular link between these benefits. Lifestyle factors such as cardiovascular diseases, metabolic syndrome, and sleep apnea will be addressed in relation to the risk they pose in developing AD and VCID, as will molecular factors known to have an impact on either the initiation or the progression of AD and/or VCID. This will include amyloid-beta clearance, oxidative stress, inflammatory responses, neurogenesis, angiogenesis, glucose metabolism, and white matter integrity. Particularly, this review will address how engaging in PE can counter factors that contribute to disease pathogenesis, and how these alterations are linked to endothelial cell function.

    Full Text Available 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.

    It is important to view track structure analysis as an application of a branch of theoretical physics (i.e., statistical physics and physical kinetics in the language of the Landau school). Monte Carlo methods and transport equation methods represent two major approaches. In either approach, it is of paramount importance to use as input the cross section data that best represent the elementary microscopic processes. Transport analysis based on unrealistic input data must be viewed with caution, because results can be misleading. Work toward establishing the cross section data, which demands a wide scope of knowledge and expertise, is being carried out through extensive international collaborations. In track structure analysis for radiation biology, the need for cross sections for the interactions of electrons with DNA and neighboring protein molecules seems to be especially urgent. Finally, it is important to interpret results of Monte Carlo calculations fully and adequately. To this end, workers should document input data as thoroughly as possible and report their results in detail in many ways. Workers in analytic transport theory are then likely to contribute to the interpretation of the results

    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 video games can lead to 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.

  19. High-energy cosmic rays and tests of basic principles of Physics

    2014-04-01

    Full Text Available 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.

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

    2010-01-01

    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.

    Full Text Available Background: Physical parameters represent an important part of the structure of sports performance and significantly contribute to the overall performance of an ice hockey player. Basic physical parameters are also an essential part of a comprehensive player assessment both during the initial NHL draft and further stages of a professional career. For an objective assessment it is desirable to know the current condition of development of monitored somatic parameters with regard to the sports discipline, performance level and gaming position. Objective: The aim of this study was to analyze and present the level of development of basic physical characteristics [Body Height (BH and Body Weight (BW] in current ice hockey players in the Canadian-American NHL, also with respect to various gaming positions. Another aim is to compare the results with relevant data of elite ice hockey players around the world. Methods: The data of 751 ice hockey players (age range: 18-43 years; 100% male from NHL (2014/2015 season are analyzed (goalkeepers, n = 67; defenders, n = 237; forwards, n = 447. Statistical data processing was performed using a single factor ANOVA and Fisher's (LSD post hoc test. The level of statistical significance was tested at a level of p ≤ .05; p ≤ .01. Effect size was expressed according to Cohen's d. Results: Current levels of monitored parameters of NHL players represent the values: BH = 186.0 ± 5.3 cm, BW = 91.7 ± 6.9 kg. Significant differences among positions were found for the BH (goalkeepers > defenders > forwards and BW (defenders > goalkeepers > forwards. Differences among forwards positions were also found for the BH (left wings > right wings > centers and BW (left wings > right wings > centers. Conclusion: The observed values represent the current level of basic physical parameters in professional ice hockey players in the NHL and can be considered

    The musculoskeletal physical examination (MSK PE) is an essential part of medical student training, and it is best taught in a hands-on, longitudinal fashion. A barrier to this approach is faculty instructor availability. "Near-peer" teaching refers to physicians-in-training teaching their junior colleagues. It is unknown whether near-peer teaching is effective in teaching this important physical examination skill. To investigate attitudes of medical students and physical medicine and rehabilitation (PM&R) residents regarding near-peer teaching in an MSK PE curriculum. Qualitative, anonymous paper and online surveys. Tertiary academic center with a medical school and PM&R training program. Ninety-nine second- and third-year medical students and 13 PM&R residents in their third or fourth postgraduate year. Attitudes of second- and third-year medical students were measured immediately after their MSK PE course. Resident attitudes were measured in a single cross-sectional sample. Student attitudes were assessed via a questionnaire with 5-point Likert scales and a free-text comment section. The resident questionnaire included a combination of multiple-choice questions, rankings, free-text responses, and Likert scales. All 99 students completed the questionnaire. The majority of students (n = 79 [80%]) reported that resident involvement as hands-on instructors of examination skills was "very useful," and 87 (88%) indicated that resident-led small discussion groups were "very helpful" or "somewhat helpful." Fifty-seven of 99 students (58%) reported that the resident-facilitated course was "much better" than courses without resident involvement. Twelve of 13 eligible residents completed the survey, and of those, 8 found teaching "very helpful" to their MSK knowledge, and 11 became "somewhat" or "much more confident" in clinical examination skills. Our study supports educational benefits to medical students and resident instructors in our MSK PE program. We recommend

    Elderly population is considered as a vulnerable group and prone to develop multiple medical problems. This aging population is rapidly increasing in developing countries especially in Thailand. Methods: This study was a quasi-experimental study to evaluate the effectiveness of Group-Mediated Lifestyle Physical Activity program on change health benefit in physical activity among elderly people by using validated and reliable Global Physical Activity Questionnaire-GPAQv2. The study was conducted in Phranakhonsiayutthaya district, Ayutthaya province due to its population being the second highest elderly in the Central Region of Thailand. A total of 102 persons of age 60 and over who could read and write Thai language were selected purposively. However, 52 elderly were enrolled in the intervention group and 50 were enrolled for the control group. General Linear Model repeated-measures ANOVA was used to evaluate the effects of Group-Mediated Lifestyle Physical Activity (GLPA) program on change health benefit in physical activity among elderly. Results: Overall health benefit at baseline were similar between intervention and control group and found statistically non-significant with p-value 0.638 (>0.05). However, the mean score of health benefit was 23.21 ± 29.23 in intervention group and 20.74 ± 23.18 in control group. One third of participants of intervention group had not found health benefit due to physical activity while in control group this number was more than half. After elderly received Group-Mediated Lifestyle Physical Activity program intervention for 6 month found significant statistical differences as compared with mean score at baseline (health benefit 6 month, intervention group =40.7 ± 34.28 and control group =4.56 ± 8.79). Conclusion: The effect of Group-Mediated Lifestyle Physical Activity program change intervention was statistically significant in health benefit after intervention program between intervention and control group.

    Superthermal energetic particles (EP) often drive shear Alfven waves unstable in magnetically confined plasmas. These instabilities constitute a fascinating nonlinear system where fluid and kinetic nonlinearities can appear on an equal footing. In addition to basic science, Alfven instabilities are of practical importance, as the expulsion of energetic particles can damage the walls of a confinement device. Because of rapid dispersion, shear Alfven waves that are part of the continuous spectrum are rarely destabilized. However, because the index of refraction is periodic in toroidally confined plasmas, gaps appear in the continuous spectrum. At spatial locations where the radial group velocity vanishes, weakly damped discrete modes appear in these gaps. These eigenmodes are of two types. One type is associated with frequency crossings of counterpropagating waves; the toroidal Alfven eigenmode is a prominent example. The second type is associated with an extremum of the continuous spectrum; the reversed shear Alfven eigenmode is an example of this type. In addition to these normal modes of the background plasma, when the energetic particle pressure is very large, energetic particle modes that adopt the frequency of the energetic particle population occur. Alfven instabilities of all three types occur in every toroidal magnetic confinement device with an intense energetic particle population. The energetic particles are most conveniently described by their constants of motion. Resonances occur between the orbital frequencies of the energetic particles and the wave phase velocity. If the wave resonance with the energetic particle population occurs where the gradient with respect to a constant of motion is inverted, the particles transfer energy to the wave, promoting instability. In a tokamak, the spatial gradient drive associated with inversion of the toroidal canonical angular momentum P ζ is most important. Once a mode is driven unstable, a wide variety of

    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.

    Physical activity benefits the skeleton, but there is contrasting evidence regarding whether benefits differ at different stages of growth. The current study demonstrates that physical activity should be encouraged at the earliest age possible and be continued into early adulthood to gain most skeletal benefits. The current study explored physical activity-induced bone adaptation at different stages of somatic maturity by comparing side-to-side differences in midshaft humerus properties between male throwing athletes and controls. Throwers present an internally controlled model, while inclusion of control subjects removes normal arm dominance influences. Throwing athletes (n = 90) and controls (n = 51) were categorized into maturity groups (pre, peri, post-early, post-mid, and post-late) based on estimated years from peak height velocity (10 years). Side-to-side percent differences in midshaft humerus cortical volumetric bone mineral density (Ct.vBMD) and bone mineral content (Ct.BMC); total (Tt.Ar), medullary (Me.Ar), and cortical (Ct.Ar) areas; average cortical thickness (Ct.Th); and polar Strength Strain Index (SSI P ) were assessed. Significant interactions between physical activity and maturity on side-to-side differences in Ct.BMC, Tt.Ar, Ct.Ar, Me.Ar, Ct.Th, and SSI P resulted from the following: (1) greater throwing-to-nonthrowing arm differences than dominant-to-nondominant arm differences in controls (all p benefits beginning prior to and continuing beyond somatic maturation and that a longer duration of exposure to physical activity has cumulative skeletal benefits. Thus, physical activity should be encouraged at the earliest age possible and be continued into early adulthood to optimize skeletal benefits.

    The purpose of this study was to understand perceived benefits, facilitators, disadvantages, and barriers for physical activity among South Asian adolescents in India and Canada. Thirteen focus group discussions with South Asian (origin) adolescent boys and girls of different nutritional status and socioeconomic status in rural and urban India and urban Canada. Across the groups, fitness and 'energy' were perceived to be major benefits of physical activity. In India, better academic performance was highlighted, while health benefits were well detailed in Canadian groups. In all settings, friends, family, and teachers were perceived as facilitators of as well as barriers to physical activity. Lack of a safe space to play was a major concern for urban adolescents, while academic pressures and preference for other sedentary recreational activities were common barriers across all groups. Girls were less likely than boys to be interested in physical activity, with girls' participation in India further limited by societal restrictions. The study suggests key areas for promotion of physical activity among South Asian adolescents: balance between academic pressure and opportunities for physical activity, especially in India; urban planning for a built environment conducive to physical activity; and gender-sensitive programming to promote girls' activity which also addresses culture-specific barriers.

    Full Text Available The objectives of this study were to develop calibration models for determination of water activity and the content of fat, dry matter, salt, non collagen muscle protein and pH in dry cooked sausages. Samples (n = 42 were scanned in FT-NIR Analyzer and simultaneously analyzed by standard methods. The spectra were measured in the reflectance mode with a compressive cell between 10 000 and 4 000 cm-1, averaging 100 scans. Calibration models were developed using the partial least squares (PLS method. These calibration models were checked later by crossvalidation. The following statistical values were obtained: R (correlation coefficient = 0.997 and SEC (standard error of calibration = 0.002 for water activity, R = 0.966 and SEC = 0.023 for pH, R = 0.995 and SEC = 0.970 for dry matter content, R = 0.995 and SEC = 0.045 for salt content, R = 0.965 and SEC = 0.652 for non collagen muscle protein, R = 0.996 and SEC = 0.559 for fat content. The results of the study showed that FT-NIR is a suitable method for rapid analysis of physical and chemical properties of sausages.

    Full Text Available Although countries’ gender equality is associated with important health outcomes, especially for females, it remains unclear whether gender equality is associated with leisure-time physical activity (LTPA. Data from 34 countries was acquired from the International Social Survey Program, the Pew Research Forum, the United Nations, and the World Bank. Separate analyses were conducted for 21,502 males and 26,652 females. Hierarchal nonlinear Bernoulli modeling was used to examine the association between gender equality and participation in LTPA. Both males and females residing in countries’ with higher gender equality were more likely (twice and three times more likely, respectively to report weekly LTPA than those residing in countries characterized by low gender equality. These effects persisted even when controlling for individual (i.e. age, education and country-level (i.e. population, gross domestic product covariates. However, significant variation in LTPA persisted at the country level, suggesting the need for further research. These findings provide novel evidence that both males and females benefit from gender equality. To explain these findings, we hypothesize that increased gender equality decreases the average number of offspring and, in turn, allows mothers more time for leisure, and to invest more resources in both male and female offspring, which may increase LTPA.

    The objectives of this study are to investigate the relation between obesity and labour force exit via diagnosis-specific disability benefits, and whether physical workload modifies this association. A longitudinal analysis was performed among 3 28 743 Swedish construction workers in the age of 15-65 years. Body weight and height were measured at a health examination and enriched with register information on disability benefits up to 37 years later. Diagnoses of disability benefits were categorised into cardiovascular diseases (CVDs), musculoskeletal diseases (MSDs), mental disorders and others. A job exposure matrix, based on self-reported lifting of heavy loads and working in bent forward or twisted position, was applied as a measure of physical workload. Cox proportional hazards regression analyses were performed, and the relative excess risk due to interaction (RERI) between obesity and physical workload was calculated. Obese construction workers were at increased risk of receiving disability benefits (HR 1.70, 95% CI 1.65 to 2.76), mainly through CVD (HR 2.30) and MSD (HR 1.71). Construction workers with a high physical workload were also more likely to receive a disability benefit (HR 2.28, 95% CI 2.21 to 2.34), particularly via MSD (HR 3.02). Obesity in combination with a higher physical workload increased the risk of disability benefits (RERI 0.28) more than the sum of the risks of obesity and higher physical workload, particularly for MSD (RERI 0.44). Obesity and a high physical workload are risk factors for disability benefit. Furthermore, these factors are synergistic risk factors for labour force exit via disability benefit through MSD. Comprehensive programmes that target health promotion to prevent obesity and ergonomic interventions to reduce physical workload are important to facilitate sustained employment. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    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.

    Progress is reported on non-perturbative problems in quantum field theories, including a field-theoretic issue regarding the relationship between operators on the lattice and in the continuum. The phase diagram of SU(3) lattice gauge theories with light fermions was investigated as a function of the gauge coupling and the fermion mass. A formulation of higher derivative gravity on a simplicial lattice was developed. Analytical and numerical work was carried out in two- and four-dimensional lattice gravity to study the phase diagram of the theory, the existence of nontrivial fixed points, and the question of the renormalization of the cosmological constant. A study was conducted on hadronic decay amplitudes in lattice gauge theory. Other studies conducted include: a covariant functional Schroedinger formalism for quantum field theory in curved space-time, constraints on magnetic mass, anomalies in reparameterization invariance in Type I superstrings, the Wess-Zumino action as an effective description of the anomalies of a theory, quantum fluctuations that can produce small regions of chirally symmetric phase in QCD, and supersymmetry anomalies. Also, the electric charge of a nonabelian magnetic monopole in the presence of fermions was related to a nonabelian generalization of the eta-invariant and computed exactly using Gauss' law. The mathematical connections between chiral anomalies, Levinson's theorem and symmetry breaking have been studied. The physics of fermion number fractionization was reviewed and a general topological theory was developed. The effect of instantons in the field theoretic description of the integral quantum Hall effect was studied. Some aspects of the anomaly cancellation of SO(32) superstring theory after compactification were examined. Also studied were dynamical supersymmetry brreaking and properties of quasi-crystals. 70 refs

    Digital Breast Tomosynthesis (DBT) is rapidly replacing mammography as the standard of care in breast cancer screening and diagnosis. DBT is a form of computed tomography, in which a limited set of projection images are acquired over a small angular range and reconstructed into tomographic data. The angular range varies from 15° to 50° and the number of projections varies between 9 and 25 projections, as determined by the equipment manufacturer. It is equally valid to treat DBT as the digital analog of classical tomography – that is, linear tomography. In fact, the name “tomosynthesis” stands for “synthetic tomography.” DBT shares many common features with classical tomography, including the radiographic appearance, dose, and image quality considerations. As such, both the science and practical physics of DBT systems is a hybrid between computed tomography and classical tomographic methods. In this lecture, we will explore the continuum from radiography to computed tomography to illustrate the characteristics of DBT. This lecture will consist of four presentations that will provide a complete overview of DBT, including a review of the fundamentals of DBT acquisition, a discussion of DBT reconstruction methods, an overview of dosimetry for DBT systems, and summary of the underlying image theory of DBT thereby relating image quality and dose. Learning Objectives: To understand the fundamental principles behind tomosynthesis image acquisition. To understand the fundamentals of tomosynthesis image reconstruction. To learn the determinants of image quality and dose in DBT, including measurement techniques. To learn the image theory underlying tomosynthesis, and the relationship between dose and image quality.

This paper presents the possibilities of preparing the geopolymer mixtures based on ground (dm = 31.0 μm FA, used in varying percentages to the original (unground; dm = 74.1 μm one. As a modification, fine-grain sludge from the process of washing the crushed aggregates was used as filler in order to obtain mortar-type material. The basic physical-mechanical properties of mixtures are presented and discussed in the paper, focusing on time dependence. The following standard tests were executed after 2, 7, 28, and 120 days: density, total water absorption, flexural strength, and compressive strength. Ground FA provided for positive effect in all tested parameters, while incorporation of fine portion of sludge into the geopolymer mixture does not offer a significant technical profit. On the other hand, it does not cause the decline in the properties, so the environmental effect (reduction of environmental burden can be applied through its incorporation into the geopolymer mixtures.

    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.

    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

    In the transition from elementary school to high school, the topics related to astronomy are studied within the curriculae component of physics. In this context, at some point of time a Physic's teacher at this level of education will be faced with the need to work with the contents related to this science. In this way, it is important to broaden the discussion about teacher education, as well as to apply in practice the means for it. Therefore, this work has the objective to present the results, obtained by application of a questionnaire at the beginning (a pre-test), and at the final stage by a course for physics graduates of online and classroom modalities (completed with a post-test), which was organized through the Potentially Significant Teaching Units - PSTUs; and this work also presents the level of satisfaction of them in relation to the course. It is an applied and descriptive research, and the adopted technical procedures consisted of the survey and a participatory research. The data were organized in spreadsheets and the statistical analyzes were made in the sequence, with the objective of establishing comparisons between the studied groups, of their evolution of acquired knowledge and their level of satisfaction, resulting from the development in the course. The results indicate that there has been an evolution of the student's s basic knowledge with relation to the proposed topics of Astronomy in the didactic sequences, i.e., the activities developed in the administered course created a favorable atmosphere for the learning, which is therefore contributing to the initial formation of these physics teachers.

    Full Text Available Urban green infrastructure, especially shade trees, offers benefits to the urban residential environment by mitigating direct incoming solar radiation on building facades, particularly in hot settings. Understanding the impact of different tree locations and arrangements around residential properties has the potential to maximize cooling and can ultimately guide urban planners, designers, and homeowners on how to create the most sustainable urban environment. This research measures the cooling effect of tree shade on building facades through an outdoor urban physical scale model. The physical scale model is a simulated neighborhood consisting of an array of concrete cubes to represent houses with identical artificial trees. We tested and compared 10 different tree densities, locations, and arrangement scenarios in the physical scale model. The experimental results show that a single tree located at the southeast of the building can provide up to 2.3 °C hourly cooling benefits to east facade of the building. A two-tree cluster arrangement provides more cooling benefits (up to 6.6 °C hourly cooling benefits to the central facade when trees are located near the south and southeast sides of the building. The research results confirm the cooling benefits of tree shade and the importance of wisely designing tree locations and arrangements in the built environment.

    Pilates exercises have several demonstrated physical and psychological benefits. To date, most research in this context was conducted with symptomatic or elderly people with few dependent measures. The current study examined the chronic or longitudinal effects of very low frequency, once a week, Pilates training on several physical and psychological measures, over a 10-week intervention, in young, healthy, and sedentary women. Further, the study gauged the acute effects of Pilates exercises on positive- and negative affect in 10 exercise sessions. Compared to a control group, the Pilates group exhibited significant improvements in skeletal muscle mass, flexibility, balance, core- and abdominal muscle strength, body awareness, and negative affect. This group also showed favorable changes in positive (22.5% increase) and negative affect (12.2% decrease) in nine out of ten exercise sessions. This work clearly demonstrates the acute and chronic benefits of Pilates training on both physical and psychological measures. It also reveals that even only once a week Pilates training is enough to trigger detectable benefits in young sedentary women. While this frequency is below the required levels of exercise for health, it may overcome the 'lack of time' excuse for not exercising and subsequently its tangible benefits may positively influence one's engagement in more physical activity.

    The goal was to have children and adolescents identify and rank the major perceived benefits of and barriers to healthful eating and physical activity and to suggest strategies for overcoming barriers. Semistructured, in-depth focus groups were undertaken using standardized questions and prompts. Students in grades 2 through 11(ages 7 through 17; N=213) from 34 randomly selected schools participated in 38 focus groups. Major benefits of healthful eating included improvements to cognitive and physical performance, fitness, endurance, psychological benefits, physical sensation (feeling good physically), and production of energy. Barriers included convenience, taste, and social factors. Benefits of physical activity included social benefits, enhancement of psychological status, physical sensation, and sports performance. Barriers included a preference for indoor activities, lack of energy and motivation, time constraints, and social factors. Suggested strategies for overcoming barriers included support from parents and school staff, better planning, time management, self-motivation, education, restructuring the physical environment, and greater variety of physical activities.

    Scientific process skills (SPS) are an intellectual skill to build knowledge, solve problems scientifically, train thinking skills as well as a very important part of the inquiry process and contribute to scientific literacy. Therefore, SPS is very important to be developed. This study aims to develop Student Worksheets (SW) that can trace SPS through basic physics experiments (BPE) on Melde’s law. This research uses R&D method involving 18 physics education department students who take the BPE course as a sample. The research instrument uses an SW designed with a SPS approach that have been reviewed and judged by expert, which includes observing, communicating, classifying, measuring, inferring, predicting, identifying variable, constructing hypothesis, defining variable operationally, designing experiment, acquiring and processing data to conclusions. The result of the research shows that the student’s SPS has not been trained optimally, the students’ answers are not derived from the observations and experiments conducted but derived from the initial knowledge of the students, as well as in the determination of experimental variables, inferring and hypothesis. This result is also supported by a low increase of conceptual content on Melde’s law with n-gain of 0.40. The research findings are used as the basis for the redesign of SW.

    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. Its main product is the official US evaluated nuclear data file, ENDF. The current version of this file is Version VI. All evaluations included in ENDF, as well as periodic modifications and updates to the file, are reviewed and approved by CSEWG and issued by the US Nuclear Data Center, Brookhaven National Laboratory. CSEWG is comprised of volunteers from the US 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 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

    Full Text Available Introduction: Aging process leads to increased risk of functional impairments and diseases occurrence. Sedentary lifestyle is one of the main risk factors the occurrence of chronic disease such a diabetes and cardiovascular disease. On the other hand, results of many studies showed that regular physical activity (PA and physical exercise (PE could decrease the risk of these hazards. Last decades were fruitful in developing evidence-based recommendations for physical activity and exercise in older people, therefore it is worth to examine dynamics of development and the similarities between different recommendations.  Material and methods: Articles in the EBSCO database have been analyzed using keywords: older people, physical exercise, physical activity, recommendations, aerobic training, resistance training. Results: Studies showed that people who were more active during lifetime, have greater self-efficacy, better physical and mental health status and in general higher satisfaction on the autumn of their life. Every analyzed recommendation underlies the negative consequences of sedentary activity, however, there is no evidence-based “cut-off” point. Similarly, there is not clear optimal “dose” of PA or PE to prescribe for older patients. Conclusions: It seems that undertaking light level of PA activity is more beneficial than none PA or sedentary lifestyle. The newest recommendations underlie the possibility of the existence of positive linear relationship between the level of PA and health benefits: every additional amount of time spent on PA during week could be related with additional health benefit

    participants with mild hypertension (11 and 7 mm Hg decrease, respectively) and participants with prehypertension (10 and 7 mm Hg decrease, respectively). Meta-analysis of recreational football determined the impact on resting heart rate as most likely extremely largely beneficial (ES=6.03 beats/min; 95% CI 4.43 to 7.64) when compared with non-active groups. The observed recreational football effect on fat mass was most likely largely beneficial (ES=1.72 kg; 95% CI 0.86 to 2.58) and the effect on countermovement jump (CMJ) performance was most likely very largely beneficial (ES=2.27 cm; 95% CI 1.29 to 3.25) when compared with non-active groups. Possibly beneficial decreases were found in low-density lipoprotein levels (ES=0.21 mmol/L; 95% CI 0.06 to 0.36). Possibly largely beneficial effect was observed for DBP in comparison with continuous running training. Small harmful and unclear results were noted for SBP, fat and lean body mass, body mass index, as well as muscular fitness when compared with running and Zumba training. The present meta-analysis demonstrated multiple broad-spectrum benefits of recreational football on health-related physical fitness compared with no-exercise controls, including improvements in blood pressure, resting heart rate, fat mass, low-density lipoprotein cholesterol and CMJ performance. Additionally, recreational football is efficient and effective as Zumba and continuous running exercise regimens with highlighted social, motivational and competitive components. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Physical activity (PA) is recommended for stable patients with advanced heart failure (HF). We evaluated expected health benefits of PA and social support as facilitators of PA, and physical symptom distress and psychological distress (depression, anxiety) as barriers to PA. Additionally, we investigated if facilitators of PA are of particular importance for patients who report barriers. We analyzed data assessed at time of waitlisting in 231 ambulatory patients (53.4 ± 10.3 years, 18 % women) who were enrolled in the multisite Waiting for a New Heart Study in 1 Austrian and 16 German hospitals. Self-reported everyday PA scores (number of activities, duration of activities) was regressed on demographic characteristics and indicators of disease severity (ejection fraction, peak oxygen consumption), facilitators (expected health benefits of PA, perceived emotional support, perceived support for PA), and barriers to PA (physical symptom distress, psychological distress). Interaction terms of facilitators with barriers were also examined. PA was positively associated with higher peak oxygen consumption, validating self-reported PA. Regarding facilitators, expected health benefits of PA were independently associated with higher PA (p values barriers, depression tended to be associated with fewer activities (p = 0.068). However, in the presence of barriers (depression, physical symptoms), feeling supported for being physically active was positively associated with PA (p values < 0.05). Interventions to improve PA may benefit from strengthening positive expectations of health outcomes associated with everyday PA and fostering PA-specific social support for those distressed by HF symptoms or depression.

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

    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. 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. 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. 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 increasing physical activity time. Though children play

    The trans-contextual model (TCM) is an integrated model of motivation that aims to explain the processes by which agentic support for autonomous motivation in physical education promotes autonomous motivation and physical activity in a leisure-time context. It is proposed that perceived support for autonomous motivation in physical education is related to autonomous motivation in physical education and leisure-time contexts. Furthermore, relations between autonomous motivation and the immediate antecedents of intentions to engage in physical activity behaviour and actual behaviour are hypothesized. The purpose of the present study was to incorporate the constructs of basic psychological need satisfaction in the TCM to provide a more comprehensive explanation of motivation and demonstrate the robustness of the findings of previous tests of the model that have not incorporated these constructs. Students (N=274) from Greek secondary schools. Participants completed self-report measures of perceived autonomy support, autonomous motivation, and basic psychological need satisfaction in physical education. Follow-up measures of these variables were taken in a leisure-time context along with measures of attitudes, subjective norms, perceived behavioural control (PBC), and intentions from the theory of planned behaviour 1 week later. Self-reported physical activity behaviour was measured 4 weeks later. Results supported TCM hypotheses. Basic psychological need satisfaction variables uniquely predicted autonomous motivation in physical education and leisure time as well as the antecedents of intention, namely, attitudes, and PBC. The basic psychological need satisfaction variables also mediated the effects of perceived autonomy support on autonomous motivation in physical education. Findings support the TCM and provide further information of the mechanisms in the model and integrated theories of motivation in physical education and leisure time.

    The purpose of this study was to examine the confidence levels that community college students have in transferring basic math skills to science classes, as well as any factors that influence their confidence levels. This study was conducted with 196 students at a community college in central Mississippi. The study was conducted during the month of November after all of the students had taken their midterm exams and received midterm grades. The instrument used in this survey was developed and validated by the researcher. The instrument asks the students to rate how confident they were in working out specific math problems and how confident they were in working problems using those specific math skills in physics and chemistry. The instrument also provided an example problem for every confidence item. Results revealed that students' demographics were significant predictors in confidence scores. Students in the 18-22 year old range were less confident in solving math problems than others. Students who had retaken a math course were less confident than those who had not. Chemistry students were less confident in solving math problems than those in physics courses. Chemistry II students were less confident than those in Chemistry I and Principals of Chemistry. Students were least confident in solving problems involving logarithms and the most confident in solving algebra problems. In general, students felt that their math courses did not prepare them for the math problems encountered in science courses. There was no significant difference in confidence between students who had completed their math homework online and those who had completed their homework on paper. The researcher recommends that chemistry educators find ways of incorporating more mathematics in their courses especially logarithms and slope. Furthermore, math educators should incorporate more chemistry related applications to math class. Results of hypotheses testing, conclusions, discussions, and

    The methodology for plasma-turbulence code validation is discussed, with focus on the quantities to use for the simulation-experiment comparison, i.e., the validation observables, and application to the TORPEX basic plasma physics experiment [A. Fasoli et al., Phys. Plasmas 13, 055902 (2006)]. The considered validation observables are deduced from Langmuir probe measurements and are ordered into a primacy hierarchy, according to the number of model assumptions and to the combinations of measurements needed to form each of them. The lowest levels of the primacy hierarchy correspond to observables that require the lowest number of model assumptions and measurement combinations, such as the statistical and spectral properties of the ion saturation current time trace, while at the highest levels, quantities such as particle transport are considered. The comparison of the observables at the lowest levels in the hierarchy is more stringent than at the highest levels. Examples of the use of the proposed observables are applied to a specific TORPEX plasma configuration characterized by interchange-driven turbulence.

    Full Text Available This article is a presentation of “Mathematical and Physical Basics in Informatics” Module projected as part of universal baccalaureate model realized in Minin State Pedagogical University, Nizhny Novgorod, within the educational program for an extended group of qualifications “Informatics and Calculating Machines”. Module authors defined a strategy for baccalaureates preparation in the field of informational technology, which is realized due to a bunch of principles: education fundamentalization, learning systematization, activity, integration and student-centration. The principle of education fundamentalization requires consolidation of scientific and methodological preparation of students. The principle of learning systematization guarantees formation of students’ holistic ideology. The principle of integration is directed onto qualitative interdisciplinary conversion based on mutual enrichment of knowledge and skills. The principle of activity considers student personality, its formation and growth with respect to practical activity as a special form of psychical activity. The principle of student-centration is displayed as social-humanistic purpose of the educational process.

    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.

    Physical activity trends for a lower-middle income country like India suggest a gradual decline in work related physical activity and no concomitant increase in leisure time physical activity. Perceived health benefits of physical activity and intention to increase physical activity have been established as independent correlates of physical activity status. In India, not much is known about peoples' perceptions of health benefits of physical activity and their intention to increase physical activity levels. This study was performed to understand peoples' perceptions and awareness about health benefits of physical activity in a rural South Indian region. This cross-sectional study was conducted using a multistage cluster sampling design. A content validated, field tested questionnaire was administered in person by a trained interviewer in the participants' native language. The questionnaire assessed the participants' perceptions about their lifestyle (active or sedentary), health benefits of physical activity and need for increasing their physical activity. In addition, the participant's physical activity was assessed using version 2 of global physical activity questionnaire. Frequencies and percentages were used to summarise perceived health benefits of physical activity and other categorical variables. Age and body mass index were summarised using mean ± SD, whereas physical activity (MET.min.wk -1) was summarised using median and interquartile range. Four hundred fifty members from 125 randomly selected households were included in the study, of which 409 members participated. 89% (364) of participants felt they lead an active lifestyle and 83.1% (340) of participants did not feel a need to increase their physical activity level. 86.1%, (352) of the participants were physically active. Though 92.4% (378) of participants felt there were health benefits of physical activity, majority of them (75.1%) did not report any benefit related to chronic diseases. None

    2012-01-01

    This article examines the relationship between dispositional mindfulness, health behaviors (eg, sleep, eating, and exercise), and physical health. Participants included 441 college women. Women completed self-report surveys at the beginning and end of a 10-week academic quarter. The study was conducted over 5 academic quarters from fall 2008 to fall 2010. Findings indicated that higher levels of dispositional mindfulness were related to healthier eating practices, better quality of sleep, and better physical health. Dispositional mindfulness contributed to better physical health even after controlling for traditional health habits. Finally, bidirectional mediational relationships were found between healthy eating and dispositional mindfulness as well as between sleep quality and dispositional mindfulness when physical health was the outcome variable. Findings suggest that incorporating mindfulness training into programming on college campuses may be beneficial, as results indicate that dispositional mindfulness is related to positive physical health among college students.

    As the number of older adults continues to rise worldwide, the prevention of physical disability among seniors is an increasingly important public health priority. Physical exercise is among the best known methods of preventing disability, but accumulating evidence indicates that considerable variability exists in the responsiveness of older adults to standard training regimens. Accordingly, a need exists to develop tailored interventions to optimize the beneficial effects of exercise on the physical function of older adults at risk for becoming disabled. The present review summarizes the available literature related to the use of adjuvant or alternative strategies intended to enhance the efficacy of exercise in improving the physical function of older adults. Within this work, we also discuss potential future research directions in this area. Copyright © 2014 American Academy of Physical Medicine and Rehabilitation. Published by Elsevier Inc.

    Full Text Available Consumer behaviour in 2016 shows that (retailers need online/offline integration to better serve their clients. An important distinguishing feature of the physical shop is how it can offer consumers a shopping experience. This study uses two experiments to research the extent a fashion store’s shopping experience can be presented to consumers via visual material (a regular photo, a 360-degree photo and a virtual reality photo of the shop without the consumers being in the shop itself. The effects of these visual materials will also be measured in (among others terms of purchase intention, visiting intention to the physical shop and online visit satisfaction. A theoretical framework is used to substantiate how the three types of pictures can be classified in terms of medium richness. The completed experiments show, among other outcomes, that consumers who saw the virtual reality photo of the shop have a more positive shopping experience, a higher purchase intention, a higher intention to visit the physical shop and more online visit satisfaction than people who have only seen the regular photo or the 360-degree photo of the shop. Enjoyment and novelty seem to partly explain these found effects. Keywords: Computer science, Psychology

    To identify the perceived benefits of and barriers to clinical supervision of physical therapy (PT) students. In this qualitative descriptive study, three focus groups and six key-informant interviews were conducted with clinical physical therapists or administrators working in acute care, orthopaedic rehabilitation, or complex continuing care. Data were coded and analyzed for common ideas using a constant comparison approach. Perceived barriers to supervising students tended to be extrinsic: time and space constraints, challenging or difficult students, and decreased autonomy or flexibility for the clinical physical therapists. Benefits tended to be intrinsic: teaching provided personal gratification by promoting reflective practice and exposing clinical educators to current knowledge. The culture of different health care institutions was an important factor in therapists' perceptions of student supervision. Despite different disciplines and models of supervision, there is considerable synchronicity in the issues reported by physical therapists and other disciplines. Embedding the value of clinical teaching in the institution, along with strong communication links among academic partners, institutions, and potential clinical faculty, may mitigate barriers and increase the commitment and satisfaction of teaching staff.

    As the number of older adults continues to rise worldwide, the prevention of physical disability among seniors is an increasingly important public health priority. Physical exercise is among the best known methods of preventing disability, but accumulating evidence indicates that considerable variability exists in the responsiveness of older adults to standard training regimens. Accordingly, a need exists to develop tailored interventions to optimize the beneficial effects of exercise on the physical function of older adults at risk for becoming disabled. The present review summarizes the available literature related to the use of adjuvant or alternative strategies intended to enhance the efficacy of exercise in improving the physical function of older adults. Within this work, we also discuss potential future research directions in this area. PMID:24361365

    The Affordable Care Act of 2010 establishes American Health Benefit Exchanges. The benefit design of insurance plans in state health insurance exchanges will be based on the structure of existing small-employer-sponsored plans. The purpose of this study was to describe the structure of the physical therapy benefit in a typical Blue Cross Blue Shield (BCBS) preferred provider organization (PPO) health insurance plan available in the individual insurance market in 2011. A cross-sectional survey design was used. The physical therapy benefit within 39 BCBS PPO plans in 2011 was studied for a standard consumer with a standard budget. First, whether physical therapy was a benefit in the plan was determined. If so, then the structure of the benefit was described in terms of whether the physical therapy benefit was a stand-alone benefit or part of a combined-discipline benefit and whether a visit or financial limit was placed on the physical therapy benefit. Physical therapy was included in all BCBS plans that were studied. Ninety-three percent of plans combined physical therapy with other disciplines. Two thirds of plans placed a limit on the number of visits covered. The results of the study are limited to 1 standard consumer, 1 association of insurance companies, 1 form of insurance (a PPO), and 1 PPO plan in each of the 39 states that were studied. Physical therapy is a covered benefit in a typical BCBS PPO health insurance plan. Physical therapy most often is combined with other therapy disciplines, and the number of covered visits is limited in two thirds of plans.

    The American Heart Association (AHA) advocates for CPR education as a requirement of secondary school curriculum. Unfortunately, many states have not adopted CPR education. Our aim was to investigate a low-cost, time effective method to educate students on Basic Life Support (BLS), including reeducation. This is a prospective, randomized study. Retention was assessed at 4 months post-initial education. Education was performed by AHA-certified providers during a 45-minute physical education class in a middle school in Florida. This age provides opportunities for reinforcement through high school, with ability for efficient learning. The study included 41 Eighth grade students. Students were randomized into two groups; one group received repeat education 2 months after the first education, the second group did not. All students received BLS education limited to chest compressions and usage of an Automated External Defibrillator. Students had skills and knowledge tests administered pre- and post-education after initial education, and repeated 2 and 4 months later to assess retention. There was a significant increase in CPR skills and knowledge when comparing pre- and post-education results for all time-points ( p  < 0.001). When assessing reeducation, a significant improvement was noted in total knowledge scores but not during the actual steps of CPR. Our study indicates significant increase in CPR knowledge and skills following a one-time 45-minute session. Reeducation may be useful, but the interval needs further investigation. If schools across the United States invested one 45-60-minute period every school year, this would ensure widespread CPR knowledge with minimal cost and loss of school time.

    2015-01-01

    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.

  19. Perceived Barriers, Facilitators and Benefits for Regular Physical Activity and Exercise in Patients with Rheumatoid Arthritis: A Review of the Literature.

    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.

    Full Text Available This study investigated whether physical activity levels and other outcomes were maintained at 1-year from completion of a 2-year telerehabilitation intervention in COPD. During the post-intervention year, nine patients with COPD (FEV1 % of pred. 42.4±19.8%; age 58.1±6 years were encouraged to exercise on a treadmill at home and monitor daily symptoms and training sessions on a webpage as during the intervention. Participants were not provided supervision or motivational support. Physical activity levels decreased from 3,806 steps/day to 2,817 steps/day (p= 0.039. There was a decline in time spent on light physical activity (p=0.009, but not on moderate-to-vigorous activity (p=0.053. Adherence to registration of symptoms and training sessions decreased significantly. Other outcomes including health status, quality of life, anxiety and depression, self-efficacy, and healthcare utilization did not change significantly. In conclusion, provision of equipment for self-management and unsupervised home exercise might not be enough to maintain physical activity levels.

    (1) Background: Green physical activity promotes physical health and mental wellbeing and interesting questions concern effects of this information on designing indoor exercise environments. This study examined the physical and emotional effects of different nature-based environments designed for indoor treadmill running; (2) Methods: In a counterbalanced experimental design, 30 participants performed three, twenty-minute treadmill runs at a self-selected pace while viewing either a static nature image, a dynamic nature image or self-selected entertainment. Distance ran, heart rate (HR) and five pre-and post-exercise emotional states were measured; (3) Results: Participants ran farther, and with higher HRs, with self-selected entertainment compared to the two nature-based environment designs. Participants attained lowered anger, dejection, anxiety and increased excitement post exercise in all of the designed environments. Happiness increased during the two nature-based environment designs compared with self-selected entertainment; (4) Conclusions: Self-selected entertainment encouraged greater physical performances whereas running in nature-based exercise environments elicited greater happiness immediately after running.

    Information regarding factors that affect the initial step to exercise behavior change among persons with physical disabilities or chronic health conditions is available in the literature but much less is known regarding perceived benefits and barriers to exercise among those who are regularly active. The purpose of this study was to examine the perceived benefits and barriers to exercise among persons with physical disabilities or chronic health conditions within action or maintenance stages of exercise. Participants (n = 152) completed the Exercise Benefits and Barriers Scale (EBBS). For data analyses, disabilities and health conditions were grouped as neuromuscular, orthopedic, cardiovascular/pulmonary, or multiple conditions. Multivariate analysis of variance (MANOVA) was conducted to determine if mean differences on EBBS benefits and barriers scores existed among disability types, between sexes, among age groups, and between physical activity levels. Sum scores were computed to determine the strongest benefit and barrier responses. No significant mean differences in EBBS scores were found between disability types, sexes, age groups, or physical activity levels (p > 0.05). Strongest benefit responses varied by group. Strongest barrier responses were the same for all demographic groups: "Exercise tires me," "Exercise is hard work for me," and "I am fatigued by exercise." EBBS scores were similar across disability/health condition, sex, age, and physical activity level. Primary benefits reported were in the areas of improved physical performance and psychological outlook whereas the primary barriers were in the area of physical exertion.

    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.

    Over the last decade, low-temperature plasma (LTP) technology has reached the life sciences and introduced the benefits of using such technology at atmospheric pressure for medical applications. The active elements from LTP, such as reactive molecular species, charged particles and photons, appear to react with biomolecules on wounds and at bleeding points. This action by LTP might be analogous with semiconductor fabrication techniques such as etching and surface modification. From this perspective, we discuss the general aspects and principles of LTP devices used at atmospheric pressure in wound care and hemostasis as an interdisciplinary fusion of applied physics and pathology.

    Some basic explanations are given of the principles underlying the nuclear fuel cycle, starting with the physics of atomic and nuclear structure and continuing with nuclear energy and reactors, fuel and waste management and finally a discussion of economics and the future. An important aspect of the fuel cycle concerns the possibility of ''closing the back end'' i.e. reprocessing the waste or unused fuel in order to re-use it in reactors of various kinds. The alternative, the ''oncethrough'' cycle, discards the discharged fuel completely. An interim measure involves the prolonged storage of highly radioactive waste fuel. (UK)

The population from which samples were taken are football referees of the Sarajevo Canton, 90 of them, age span from 18- 45 years of age and who have met the criteria for getting a license to be referees in football matches in the next season at all levels of competition in Bosnia and Herzegovina. The sample of variables in this research covers areas of basic motorics (18, theoretic knowledge laws of the games (17 and the estimate of success in refereeing in football games (7 variables. The results of the final analysis show that the whole system of variables which in this research represent basic physical capabilities and the knowledge Laws of the game by the football referees of the Sarajevo Canton has a statistical connection with the system of variables which in this research makes the success of refereeing of football referees. Since football is an activity that has almost the most complexity (referees are a part of football, we can say that the selected system of variables has a relatively good connection for success and that these variables are very important in order for one referee to perform his task as good as possible at one match.. Of course during the training process attention should be given on the development of all basic physical capabilities, and not only one dimension of the physical area because in general we have to be physically and cognitively be present in order to finish the game at a high rhythm but making mistakes the least as possible

  12. Promoting Well-Being in Old Age: The Psychological Benefits of Two Training Programs of Adapted Physical Activity

    2018-05-01

    Full Text Available In the last few decades, the relationship between physical conditions and mental health has increasingly attracted the interest of researchers and professionals across disciplines. This relationship is especially relevant in old age, as the challenges posed by aging at various levels represent crucial concerns for policy makers. Due to the remarkable increase in life expectancy across countries, sustainable prevention strategies are needed to help individuals preserve psychophysical well-being in old age. In particular, the regular practice of a moderately intense physical activity is recommended by the World Health Organization to enhance balance, prevent falls, strengthen muscles, and promote psychophysical well-being. Daily physical exercise represents a beneficial and low-cost strategy, easily accessible to the general population and potentially customizable to specific needs through brief training programs. Based on these premises, the present research aimed at longitudinally evaluating mental well-being among 58 Italian people aged 67–85, who were involved in two Adapted Physical Activity (APA training programs. Inclusion criteria for participation comprised high autonomy levels in daily activities, no cognitive impairment, sedentary habits or only occasional performance of moderate physical activity. Based on physical and functional assessment, 39 participants joined a program of adapted motor activity (PoliFit; Study 1, while 19 participants attended a variant program specifically designed for people with osteoporosis (OsteoFit; Study 2. Well-being dimensions were assessed through the Mental Health Continuum-Short Form, the Emotion Regulation Questionnaire and the Satisfaction with Life Scale. Physical functioning were evaluated before and after the programs through the Short Physical Performance Battery and the Handgrip Dynamometer Jamar Test. Findings highlighted that, besides physical benefits, participants reported significantly

    Intensity, frequency and duration of physical activity may contribute in different ways to the maintenance of cardiovascular health. Their relative importance may also change at different stages in life and this should be taken into account for activity recommendations. The relationship of frequency and duration of leisure-time physical activities with cardiovascular risk factors was studied in 4942 male and 5885 female participants aged 50-69, of the German Cardiovascular Prevention Study (1984-1991). After adjustment for several possible confounders, women with modest levels (2-12 times per month, 0.5-2 h per week) of moderate-to-vigorous activity (> or =5 kcal/kg/h) had significantly lower systolic blood pressure (-1.8%), resting heart rate (-3.1%) and body mass index (-3.2%) values than sedentary women. Beneficial differences increased with frequency and duration of activity. Light activities (3-4.5 kcal/kg/h), conducted > or =5 times a week, were significantly associated with favourable lower diastolic blood pressure (-1.4%), resting heart rate (-2.3%) among women, and body mass index (women -2.9%, men -2.2%) among both genders. Recommended activity levels (> or =5 times, > or =3.5 h weekly) were associated with a lower prevalence of multiple risk factors (odds ratio [OR] = 0.55, 95% CI: 0.41-0.75 for men and OR = 0.44 95% CI: 0.31-0.63 for women). For sedentary elderly, even less physical activity than currently recommended, is likely to improve the cardiovascular risk profile.

    2014-06-01

    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.

    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.

    2015-06-01

    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.

    After an historical presentation of the elaboration of the energy concept, this document recalls, first, the basic physical principles linked with this concept: first and second principle of thermodynamics, dynamics of irreversible processes, hierarchy of elementary interactions. Then, their consequences on energy problems are examined by comparing the different common types of energy from different points of view: concentration, degradation, transport, storage, reserves and harmful effects. These comparisons rely on the characteristic values of the data involved. (J.S.)

    Ogoh, Kazutoshi

    "Basic Natural Science" for freshmen at Miyazaki Prefectural Nursing University has a component including physics. Here students learn three principles of thermal transfer; conduction, radiation, and convection through a series of experiments. The purpose of these experiments is to understand the structure of a method for the caring of breathing and temperature of patients as written in "Ventilation and Warming", the first chapter of F. Nightingale's Notes on Nursing. Students can then apply this structure to retain fresh air in today's hospital rooms, and can then appreciate studying real physics incorporated into fundamental knowledge for nursing practice.

    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. 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). 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. 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.

    Background The evaluation and management of stress are important for the prevention of both depression and cardiovascular disease. In addition, the maintenance of the oral condition of the elderly is essential to enable them to stay healthy, especially to prevent aspiration pneumonia and improve mental health in an aging society. Therefore, we examined the efficacy of singing on the oral condition, mental health status, and immunity of the elderly to determine if singing could contribute to the improvement of their physical condition. Methods Forty-four subjects (10 men, 34 women), aged 60 years or older, participated in this study. The efficacy of singing on mental health status and immunocompetence was examined by swallowing function, oral condition, blood, and saliva tests, as well as through questionnaires taken before and after singing. Results The results showed that the amount of saliva increased and the level of cortisol, a salivary stress marker, decreased after singing. The Visual Analog Scale (VAS) scores for feeling refreshed, comfortable, pleasurable, light-hearted, relieved, and relaxed; the tension and confusion subscale score; and the total mood disturbance (TMD) score of the Profile of Mood States (POMS) all showed improvements. Furthermore, the same tendencies were shown regardless of whether or not the subjects liked singing. Conclusions Our results suggest that singing can be effective in improving the mental health and oral condition of the elderly. PMID:24864162

    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. © 2014 Wiley Periodicals, Inc.

    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).

    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. The DPGs are now led by the Commissioning and Run Coordinator deputy (Darin Acosta) and will appear in the correspond¬ing column in CMS bulletins. On the physics side, the physics object groups are charged with the reconstruction of physics objects, the tuning of the simulation (in collaboration with the DPGs) to reproduce the data, the provision of code for the High-Level Trigger, the optimization of the algorithms involved for the different physics analyses (in collaboration with the analysis gr...

    The purpose of this study was to explore possible benefits of a peer-tutored physical education programme (PTPE) in comparison with school physical education (SPE) in high school students with intellectual disability. Nineteen students with intellectual disabilities (15 boys, mean age 17.4 ± 1.7 years) were monitored during three PTPE and three SPE classes. A factorial RM-ANOVA was used to test differences on objective measured physical activity (PA), enjoyment and exertion during the two conditions, considering participants' weight condition as independent factor. During PTPE, participants reported higher light intensity PA, enjoyment and exertion than during SPE. Participants with overweight showed less inactive time and higher light intensity PA during PTPE than during SPE. The peer-tutored programme was beneficial for adolescents with intellectual disability, particularly for those in overweight condition. The higher enjoyment found during PTPE may encourage exercise participation of students with intellectual disability. © 2018 John Wiley & Sons Ltd.

    This study investigated the effects of the low-dose combined oral contraceptive (COC) 2.0 mg chlormadinone acetate (CMA)/0.03 mg ethinylestradiol (EE) (Belara, Balanca) on cycle-related physical and emotional disorders in women >or=25 years of age. A prospective, non-interventional, observational study of 3772 women over six cycles was conducted in 303 office-based gynecological centers throughout Germany. CMA/EE provided high contraceptive efficacy with a Pearl index of 0 (95% confidence interval=0.00-0.22) and was generally well tolerated, with no statistically significant weight changes during the observation period (p=.147). CMA/EE intake resulted in a statistically significant improvement in cycle-related physical and emotional symptoms, with a 67% overall reduction in sum score for number and intensity of cycle-related symptoms per patient. The results of this study in women >or=25 years of age support previous findings that 2.0 mg CMA/0.03 mg EE is an effective low-dose COC, with an excellent tolerability profile, with the additional benefits of significantly reducing both cycle-related physical and emotional symptoms (pcontraceptive treatment. Further research is warranted.

    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. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Those with mental illness are at increased risk of physical health problems. The current study aimed to examine the information available online to the Australian public about the increased risk and consequences of physical illness in those with mental health problems and the services available to address these co-morbidities. A structured online search was conducted with the search engine Google Australia (www.google.com.au) using generic search terms 'mental health information Australia', 'mental illness information Australia', 'depression', 'anxiety', and 'psychosis'. The direct content of websites was examined for information on the physical co-morbidities of mental illness. All external links on high-profile websites [the first five websites retrieved under each search term (n = 25)] were examined for information pertaining to physical health. Only 4.2% of websites informing the public about mental health contained direct content information about the increased risk of physical co-morbidities. The Australian Government's Department of Health and Ageing site did not contain any information. Of the high-profile websites, 62% had external links to resources about physical health and 55% had recommendations or resources for physical health. Most recommendations were generic. Relative to the seriousness of this problem, there is a paucity of information available to the public about the increased physical health risks associated with mental illness. Improved public awareness is the starting point of addressing this health inequity.

    Traditionally in the center of interest on quantum physics referring to schools the question lies, whether electrons and photons are now particles or waves, a question, which is often characterized by the phrase ''wave-particle dualism'', which notoriously not exists in its original meaning. Against that by the author - basing on important preparatory works of Kueblbeck and Mueller - a new concept for the treatment of quantum physics for the school was proposed, which puts ''basic facts'' in the foreground, comparable with the Kueblbeck-Mueller ''characteristic features''. The ''basic facts'' are similar to axioms of quantum physics, by means of which a large number of experiments and phenomena can be ''explained'' at least qualitatively - in a heuristic way -. Instead of the so-called ''wave-particle dualism'' here uncertainty and complementarity are put in the foreground. The new concept is in the Internet under http://www.forphys.de extensively presented with many further materials. In the partial volumes of this publication manifold and carefully elaborated teaching materials are presented, by means of which scholars can get themselves the partial set of quantum physics referring to schools by different methods like learn at stations, short referates, Internet research, group puzzle, the query-sheet or the card-index method etc. In the present 2. part materials for the ''basic facts'' of quantum physics are prepared, by which also modern experiments can be interpreted. Here deals it with the getting of knowledge and application of the ''basic Facts''. This pursues also by real scholar experiments, simulations and analogy tests. The scholars obtain so more simply than generally a deeper insight in quantum physics.

    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. PMID:19149880

    Full Text Available The prevalence of physical activity among lower educated adolescent girls is low, suggesting it is important to have insights into the complex processes that may underlie their physical activity levels. Therefore, this study aimed to examine the mediating effects of self-efficacy, perceived benefits and barriers on the associations between peer and parental variables and physical activity among lower educated adolescent girls.In total, 226 girls (mean age 16.0±1.0 years; 53% technical education; 47% vocational education from a convenience sample of 6 secondary schools in Flanders, Belgium, completed a questionnaire on their total physical activity level and related peer and parental variables (i.e. modeling of physical activity, co-participation in physical activities and encouragement to be active and personal variables (i.e. self-efficacy to be active, and specific perceived benefits of physical activity and specific barriers to be active. Mediating effects were tested using MacKinnon's product-of-coefficients test based on multilevel linear regression analyses.Higher peer and parental modeling, co-participation and encouragement were significantly related to a higher physical activity level among adolescent girls (p<0.05. Self-efficacy, the perceived benefits of having fun, being around friends or meeting new people, and not being bored and the perceived barrier of not liking physical activity mediated several associations between peer and parental variables and girls' physical activity, with some of the mediated proportions exceeding 60%.This study contributed to a better understanding of the complexity of how parental and peer factors work together with personal factors to influence the physical activity levels of adolescent girls with a lower educational level. Interventions should involve both peers and parents, as they may influence girls' physical activity both directly and indirectly through the internalisation of several personal

    Highlight the role of patient education about physical activity and exercise in the treatment of hip and knee osteoarthritis (OA). Systematic literature review from the Cochrane Library, PubMed and Wiley Online Library databases. A total of 125 items were identified, including 11 recommendations from learned societies interested in OA and 45 randomized controlled trials addressing treatment education and activity/exercise for the treatment of hip and knee osteoarthritis. In the end, 13 randomized controlled trials and 8 recommendations were reviewed (1b level of evidence). Based on the analysis, it was clear that education, exercise and weight loss are the pillars of non-pharmacological treatments. These treatments have proven to be effective but require changes in patient behaviour that are difficult to obtain. Exercise and weight loss improve function and reduce pain. Education potentiates compliance to exercise and weight loss programs, thereby improving their long-term benefits. Cost efficiency studies have found a reduction in medical visits and healthcare costs after 12 months because of self-management programs. Among non-surgical treatment options for hip and knee osteoarthritis, the most recent guidelines focus on non-pharmacological treatment. Self-management for general physical activity and exercise has a critical role. Programs must be personalized and adjusted to the patient's phenotype. This development should help every healthcare professional adapt the care they propose to each patient. Registration number for the systematic review: CRD42015032346.

    Full Text Available The work deals with the results of physical fitness of football-players of 15-16 years old in the structure of annual training cycle. There is a try to define the informative indices while estimating the athletes preparation. Selection of adequate procedures and tests is necessary for definition of frame of physical fitness of sportsmen. Analysis of experimental data has allowed to establish the information importance of components of frame of physical fitness at different stages of a year cycle of training, to eliminate for each stage of training the indicators which are not possessing reliability and a validity, and the received indicators to use as tests for carrying out the control.

  1. Benefits of Distinguishing between Physical and Social-Verbal Aspects of Behavior: An Example of Generalized Anxiety.

    Temperament traits and mental illness have been linked to varying degrees of imbalances in neurotransmitter systems of behavior regulation. If a temperament model has been carefully structured to reflect weak imbalances within systems of behavior regulation, then in the presence of mental illness, these profiles should exhibit distinct patterns consistent with symptoms of mental illness. In contrast to other temperament models used in studies of anxiety disorders, the Functional Ensemble of Temperament (FET) model differentiates not only between emotionality traits, but also between traits related to physical, social-verbal and mental aspects of behavior. This paper analyzed the predictions of the FET model, which maps 12 functional aspects of behavior to symptoms of generalized anxiety disorder (GAD) as described in the DSM/ICD. As an example, the paper describes a study of the coupling of sex, age and temperament traits with GAD using the FET framework. The intake records of 116 clients in treatment with confirmed diagnosis of GAD in a private psychological practice were compared using ANOVA against records of 146 healthy clients using their scores on the FET-based questionnaire, in age groups 17-24, 25-45, 46-65. Patients with GAD in all age groups reported significantly lower Social Endurance, Social Tempo, Probabilistic reasoning (but not in physical aspects of behavior) and higher Neuroticism than healthy individuals, however, no effects on the scales of Motor Endurance or Tempo were found. These findings show the benefits of differentiation between motor-physical and social-verbal aspects of behavior in psychological assessment of mental disorders.

    This script contains theses for an universal 'Spiral-Field-Theory' that are capable to dissolve problems in parallel from different areas which are far from each other. Starting point is the stuck principle discussion about the relationships between the Classic Physics and the Quantum Physics. Aim is the clarification of questions which remained open. In 1925 Max Planck had formulated as follows: 'The research of physics can not rest, so long not has been together-welded: on the one hand the mechanics and the electrodynamics with on the other hand the lesson of the stationary one and the radiating heat to a sole unitary theory'. The Spiral-Field-Model develops a supporting structure from General Field into which they will class the secure knowledge from experiments and well-proved theories. The most important thing of this new Final Theory is the detailed generating of all nature courses of phenomena exclusively from radiation and that in the direct meaning of the word. In the final effect the two great disciplines of the physics which are drifted from each other, become bonded together to a super ordinate theoretical building of the nature sciences. (orig.)

    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

    A double liner concept is proposed of utilizing pulsed power in investigations of Inertial Confinement Fusion (ICF) and High Energy Density Physics. In this project, an external cylindrical plasma shell (liner) magnetically imploded in the generator diode collides with the internal one. Thermal X-ray radiation brought about by a high-velocity shock wave penetrates into the internal liner cavity and irradiates a spherical target. Investigations at the ANGARA-5 generator were concentrated on a comprehensive study of physical processes and the possibility of short radiation pulse generation. Soft X-ray radiation intensities of up to 3 TW/cm{sup 2} with a 3 ns rise time were obtained. It follows from the theoretical model that for the generator current higher than 15 MA the radiation intensity should be close to the ignition threshold and magnetized plasma instabilities should be suppressed. The paper reports on the concept and the theoretical and experimental results. (author). 8 refs.

    Physical activity (PA) can have a positive impact upon health and well-being for people with spinal cord injury (SCI). Despite these benefits, people with SCI are within the most physically inactive segment of society that comprises disabled people. This original meta-synthesis of qualitative research was undertaken to explore the barriers, benefits and facilitators of leisure time physical activity (LTPA) among people with SCI. Articles published since 2000 were identified through a rigorous search of electronic databases, supported with a hand search of relevant journals and papers. In total, 64 papers were read in full, and based on inclusion criteria, 18 were relevant for review. The key themes constructed from the data were summarised, compared and synthesised. Eight interrelated concepts were identified as barriers, benefits and/or facilitators of LTPA: (i) well-being (WB); (ii) environment; (iii) physical body; (iv) body-self relationship; (v) physically active identity; (vi) knowledge; (vii) restitution narrative; (viii) perceived absences. Based on the synthesised evidence, healthcare professionals need to appreciate the relationships between the barriers, benefits and facilitators of LTPA in order to successfully promote a physically active lifestyle. Equally, a more critical attitude to PA promotion is called for in terms of possible adverse consequences.

    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.

    Full Text Available This paper summarizes a study conducted in 2013 with the purpose of predicting the failure rate of math courses taken by Pharmacy, Mathematics, Actuarial Science, Physics and Meteorology students at Universidad de Costa Rica (UCR. Using the Logistics Regression statistical techniques applied to the 2010 cohort, failure rates were predicted of students in the aforementioned programs in one of their Math introductory courses (Calculus 101 for Physics and Meteorology, Math Principles for Mathematics and Actuarial Science and Applied Differential Equations for Pharmacy. For these models, the UCR admission average, the student’s genre, and the average correct answers in the Quantitative Skills Test were used as predictor variables. The most important variable for all models was the Quantitative Skills Test, and the model with the highest correct classification rate was the Logistics Regression. For the estimated Physics-Meteorology, Pharmacy and Mathematics-Actuarial Science models, correct classifications were 89.8%, 73.6%, and 93.9%, respectively.

    2014-01-01

    Full Text Available Magnetic resonance imaging is a very complex diagnostic technique. Therefore, both practical experiences and theoretical understanding is needed for effective diagnostics. It is therefore important that physicians are sufficiently familiar with the basic physical principles of magnetic resonance. In the interpretation of physical concepts, we will rely both on the classical as well as on the quantum-mechanical view of the signal formation in magnetic resonance, which are to some extent complementary. The signal appearance in magnetic resonance imaging will be discussed. A special emphasis will be put on the role of the resonance frequency and the pulse sequences. Furthermore, the spin echo as one of the most used classical signal sequences in diagnostic investigations will be described.

    There is a body of theoretical work, and some empirical research, which suggests that non-disabled people assume people with physical disabilities are not suitable romantic partners, do not have sexual drives or desires, or are not sexually active. It has also been proposed that people with physical disabilities face barriers to sexual healthcare access which are structural as well as social. The present paper explores non-disabled South Africans' beliefs concerning the degree to which non-disabled respondents enjoy sexual and reproductive rights, and benefit from sexual and reproductive healthcare, compared to people without disability. Using a survey, we asked 1989 South Africans to estimate the degree to which people with physical disabilities and people without disability have sexual rights, and benefit from sexual and reproductive healthcare services, respectively. Respondents were more likely to support the idea that the population without disability were deserving of sexual rights compared to people with physical disabilities. Respondents were more likely to rate the degree to which people with physical disability benefit from sexual and reproductive healthcare as less than that for people without physical disabilities. These findings provide some of the first empirical support that non-disabled people perceive people with physical disabilities as having fewer sexual and reproductive rights, and deriving less benefit from sexual and reproductive health services, than the population without disability. To have diminished sexual rights, and benefit less from sexual and reproductive healthcare, we suggest, evinces a negation of the sexual and reproductive needs and capacity of people with physical disabilities.

    The effectiveness of Pilates exercise for treating people with chronic low back pain (CLBP) is yet to be established. Understanding how to identify people with CLBP who may benefit, or not benefit, from Pilates exercise and the benefits and risks of Pilates exercise will assist in trial design. The purpose of this study was to establish a consensus regarding the indications, contraindications, and precautions of Pilates exercise and the potential benefits and risks of Pilates exercise for people with CLBP. A panel of 30 Australian physical therapists experienced in the use of Pilates exercise were surveyed using the Delphi technique. Three electronic questionnaires were used to collect participant opinions. Answers to open-ended questions were analyzed thematically, combined with research findings, and translated into statements about Pilates exercise. Participants then rated their level of agreement with statements using a 6-point Likert scale. Consensus was achieved when 70% of panel members agreed or disagreed with an item. Thirty physical therapists completed the 3 questionnaires. Consensus was reached on 100% of items related to the benefits, indications, and precautions of Pilates exercise, on 50% of items related to risks, and on 56% of items related to contraindications. Participants agreed that people who have poor body awareness and maladaptive movement patterns may benefit from Pilates exercise, whereas those with pre-eclampsia, unstable spondylolisthesis, or a fracture may not benefit. Participants also agreed that Pilates exercise may improve functional ability, movement confidence, body awareness, posture, and movement control. The findings reflect the opinions of only 30 Australian physical therapists and not all health professionals nationally or internationally. These findings, therefore, need to be verified in future research trials. These findings contribute to a better understanding of the indications, contraindications, and precautions of

    The aim of this study was to explore the use of assessment strategy which can measure problem solving skills of pre-service teachers based on their cognitive style in basic physics course. The sample consisted of 95 persons (male = 15, female = 75). This study used an exploratory research with observation techniques by interview, questionnaire, and test. The results indicated that the lecturer only used paper-pencil test assessment strategy to measure pre-service teachers’ achievement and also used conventional learning strategy. It means that the lecturer did not measure pre-services’ thinking process in learning, like problem solving skills. One of the factors which can influence student problem solving skills is cognitive style as an internal factor. Field Dependent (FD) and Field Independent (FI) are two cognitive styles which were measured with using Group Embedded Figure Test (GEFT) test. The result showed that 82% of pre-service teachers were FD cognitive style and only 18% of pre-service teachers had FI cognitive style. Furthermore, these findings became the fundamental design to develop a problem solving assessment model to measure pre-service teachers’ problem solving skills and process in basic physics course.

    This paper presents the results of a study comparing the past scientific performance of high-energy physics accelerators in the Eastern bloc with that of their main Western counterparts. Output-evaluation indicators are used. After carefully examining the extent to which the output indicators used may be biased against science in the Eastern bloc, various conclusions are drawn about the relative contributions to science made by these accelerators. Where significant differences in performance are apparent, an attempt is made to identify the main factors responsible. (author)

    To test whether basic skills acquired on a virtual endoscopic surgery simulator are transferable from virtual reality to physical reality in a comparable training setting. For surgical training in laparoscopic surgery, new training methods have to be developed that allow surgeons to first practice in a simulated setting before operating on real patients. A virtual endoscopic surgery trainer (VEST) has been developed within the framework of a joint project. Because of principal limitations of simulation techniques, it is essential to know whether training with this simulator is comparable to conventional training. Devices used were the VEST system and a conventional video trainer (CVT). Two basic training tasks were constructed identically (a) as virtual tasks and (b) as mechanical models for the CVT. Test persons were divided into 2 groups each consisting of 12 novices and 4 experts. Each group carried out a defined training program over the course of 4 consecutive days on the VEST or the CVT, respectively. To test the transfer of skills, the groups switched devices on the 5th day. The main parameter was task completion time. The novices in both groups showed similar learning curves. The mean task completion times decreased significantly over the 4 training days of the study. The task completion times for the control task on Day 5 were significantly lower than on Days 1 and 2. The experts' task completion times were much lower than those of the novices. This study showed that training with a computer simulator, just as with the CVT, resulted in a reproducible training effect. The control task showed that skills learned in virtual reality are transferable to the physical reality of a CVT. The fact that the experts showed little improvement demonstrates that the simulation trains surgeons in basic laparoscopic skills learned in years of practice.

    The dose-response effects of exercise training on insulin sensitivity, metabolic risk, and quality of life were examined. Sixty-one healthy, sedentary (VO₂max: 35 ± 5 ml/kg/min), moderately overweight (BMI: 27.9 ± 1.8), young (age: 29 ± 6 years) men were randomized to sedentary living (sedentary control group; n = 18), moderate (moderate dose training group [MOD]: 300 kcal/day, n = 21), or high (high dose training group [HIGH]: 600 kcal/day, n = 22) dose physical exercise for 11 weeks. The return rate for post-intervention testing was 82-94% across groups. Weekly exercise amounted to 2,004 ± 24 and 3,774 ± 68 kcal, respectively, in MOD and HIGH. Cardiorespiratory fitness increased (P exercise groups (MOD: 32 ± 1 to 29 ± 1%; HIGH: 30 ± 1 to 27 ± 1%). Peripheral insulin sensitivity increased (P benefits were found when exercising ∼3,800 as opposed to ∼2,000 kcal/week in young moderately overweight men.

    1996-11-01

    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

    Full Text Available BACKGROUND: Central European countries belonging to the former "communist bloc" show specificities and even unique things which should not be ignored in research and preventive measures. In addressing health issues it is desirable to observe the developmental patterns in economically developed countries to avoid easily predictable negative aspects in the development of population health. Therefore it is necessary to specify associations between gender, age, occupational classification, education, etc., and lifestyles in different conditions and environments. Simultaneously it is necessary maintain specific features of environment that are consistent with active lifestyles and encourage people to maintain high walkability. AIM: The aim of this study was to analyze physical activity of the Czech population with regard to the size of the community and observe regional differences in physical activity (PA in men and women. METHODS: To determine the weekly level of PA we used randomized data set of 8256 inhabitants of the Czech Republic (3678 men and 4578 women. All respondents were reached personally by trained distributors (college students to participate in a research study using the Czech version of the IPAQ questionnaire (also as a part of ANEWS. Data collection was carried out regularly in Spring (March-May and Autumn (September- November periods from 2005 to 2009. Region of the Capital City of Prague has been excluded from the regional analysis. RESULTS: Regional comparisons of total weekly PA shows the minimum differences within the Czech Republic [H(15, 8256 = 103,55; p < 0,001; η2 = 0,01]. The lowest level of PA show both men and women in Ustecky and Moravskoslezsky region, highest level of PA represent population of the region consisted from regions Pardubicky, Kralovehradecky and Vysocina. Size of the community has a significant impact on the overall weekly PA in adult population of the Czech Republic. The results confirm the trend that

    Little is known about any differences between young people with chronic physical conditions who do and do not apply for disability benefits in young adulthood for providing insights for future policy and rehabilitation care. We aimed to identify predictors during adolescence of receiving disability benefits in young adulthood and to compare recipients and non-recipients of benefits in social participation and psychosocial outcomes in young adulthood. Follow-up study of 18 to 25 year olds with various chronic conditions who at adolescent age completed a web-based survey (n=518; T0). The outcome was receiving disability benefits (yes or no). Associations with background characteristics, social participation, and impact of the chronic condition were explored with stepwise multivariate modelling, using T0 variables. Differences between recipients and non-recipients were explored using chi-square tests and t-tests. Receiving disability benefits in young adulthood was associated with greater extent of physical disability, receiving less special education, absenteeism at school/work, and low health-related quality of life during adolescence. In young adulthood, recipients of benefits reported higher perceived impact of the chronic condition on their school/work career and lower quality of life than non-recipients. Social participation varied across domains. This study provides important insights into the characteristics of a vulnerable subgroup of young people with chronic physical conditions. Disability benefit recipients experienced more impact of their chronic condition and reported a lower health-related quality of life over time than non-recipients. Rehabilitation professionals are encouraged to use patient-reported outcomes to address the lived experiences and screen the need for psychosocial support of this vulnerable subgroup of young people with chronic physical conditions.

  11. Dopamine antagonism decreases willingness to expend physical, but not cognitive, effort: a comparison of two rodent cost/benefit decision-making tasks.

    Successful decision making often requires weighing a given option's costs against its associated benefits, an ability that appears perturbed in virtually every severe mental illness. Animal models of such cost/benefit decision making overwhelmingly implicate mesolimbic dopamine in our willingness to exert effort for a larger reward. Until recently, however, animal models have invariably manipulated the degree of physical effort, whereas human studies of effort have primarily relied on cognitive costs. Dopamine's relationship to cognitive effort has not been directly examined, nor has the relationship between individuals' willingness to expend mental versus physical effort. It is therefore unclear whether willingness to work hard in one domain corresponds to willingness in the other. Here we utilize a rat cognitive effort task (rCET), wherein animals can choose to allocate greater visuospatial attention for a greater reward, and a previously established physical effort-discounting task (EDT) to examine dopaminergic and noradrenergic contributions to effort. The dopamine antagonists eticlopride and SCH23390 each decreased willingness to exert physical effort on the EDT; these drugs had no effect on willingness to exert mental effort for the rCET. Preference for the high effort option correlated across the two tasks, although this effect was transient. These results suggest that dopamine is only minimally involved in cost/benefit decision making with cognitive effort costs. The constructs of mental and physical effort may therefore comprise overlapping, but distinct, circuitry, and therapeutic interventions that prove efficacious in one effort domain may not be beneficial in another.

  12. Mental health benefits of neighbourhood green space are stronger among physically active adults in middle-to-older age: evidence from 260,061 Australians.

    While many studies report that green spaces promote mental health, some suggest the psychological benefits of physical activity are amplified if participation occurs within greener environs. We investigated whether this relationship could be observed among adults in middle-to-older age. Multilevel logit regression was used to investigate association between green space and psychological distress (Kessler scores of 22+) among 260,061 Australians over 45 years old living in New South Wales (2006-2009). Physical activity was measured using the Active Australia survey. Percentage green space was estimated within a 1-kilometre of residence. In comparison to residents of the least green areas, those in the greenest neighbourhoods were at a lower risk of psychological distress (Odds Ratio 0.83, 95% CI: 0.76, 0.92) and were less sedentary (0.81: 0.77, 0.87). An interaction was observed between physical activity and green space (p=0.0028). More green space did not appear to benefit mental health among the least active (0.99: 0.85, 1.15), but there was a protective association for the more physically active (0.82: 0.67, 0.99). For adults in middle-to-older age, green spaces are not only important for promoting physical activity, but the mental health benefits of greener environs appear contingent upon those active lifestyles. © 2013.

    The beneficial effects of fly ash application shown herein are expected to encourage future disposal of the material in agricultural soils. It is foreseen, however, that fly ash disposal in agricultural soils would be unsuccessful if adverse effects on crop production result from its misuse. It seems evident, therefore, that quality control measures will be required to insure proper disposal of the material in agricultural soils. It will be necessary to consider differences in chemical properties of various samples of fly ash and in chemical reactions of samples of fly ash and soils. Differences in tolerances of plants to soluble salt damage and to specific nutrient deficiencies and toxicities will also have to be taken into account. 9 tables.

  17. Treatment of traumatised refugees with basic body awareness therapy versus mixed physical activity as add-on treatment: Study protocol of a randomised controlled trial.

    Treatment of traumatised refugees is one of the fields within psychiatry, which has received little scientific attention. Evidence based treatment and knowledge on the efficiency of the treatment for this complex patient group is therefore scarce. This leads to uncertainty as to which treatment should be offered and potentially lowers the quality of life for the patients. Chronic pain is very common among traumatised refugees and it is believed to maintain the mental symptoms of trauma. Hence, treating chronic pain is believed to be of high clinical value for this patient group. In clinical studies, physical activity has shown a positive effect on psychiatric illnesses such as depression and anxiety and for patients with chronic pain. However, scientific knowledge about physical activity as part of the treatment for traumatised refugees is very limited and no guidelines exist on this topic. This study will include approximately 310 patients, randomised into three groups. All three groups receive psychiatric treatment as usual for the duration of 6-7 months, consisting of consultations with a medical doctor including pharmacological treatment and manual-based Cognitive Behavioural Therapy. The first group only receives treatment as usual while the second and the third groups receive either Basic-Body Awareness Therapy or mixed physical activity as add-on treatments. Each physical activity is provided for an individual 1-hour consultation per week, for the duration of 20 weeks. The study is being conducted at the Competence Centre for Transcultural Psychiatry, Mental Health Centre Ballerup in the Capital Region of Denmark. The primary endpoint of the study is symptoms of Post Traumatic Stress Disorder; the secondary endpoints are depression and anxiety as well as quality of life, functional capacity, coping with pain, body awareness and physical fitness. This study will examine the effect of physical activity for traumatised refugees. This has not yet been done in a

    Full Text Available Research from a variety of scientific fields suggests that physical activity in nature and feelings of connection to nature enhance psychological health and well-being. This study investigated the psychological health and well-being impact of the physical activity environment for those already undertaking the recommended weekly amount of physical activity. This topic is important for the design of health and well-being environments and interventions involving physical activity. Participants (N = 262 aged 18–71 years (M = 34.5, SD = 13.1 who met the UK physical activity guidelines completed the Nature Relatedness Scale, the trait section of the State Trait Inventory for Cognitive and Somatic Anxiety and the Psychological Well-Being Scale. Analysis via Multivariate ANOVA indicated that participants who engaged in outdoor physical activity reported significantly lower somatic anxiety levels and higher Nature Relatedness experience (NRexp. Significant results were not evident for wellbeing. Hierarchical regressions revealed that the psychological well-being facet of autonomy, NRexp, and outdoor physical activity predicted lower somatic anxiety, whereas indoor physical activity predicted higher somatic anxiety. Results indicate that somatic anxiety is lower for outdoor physical activity participation, and that outdoor activity, in conjunction with autonomy and NRexp, predicts lower anxiety levels. The findings extend previous work by demonstrating the impact of the physical activity environment on anxiety levels, as well as the contribution of outdoor physical activity and well-being facets to the previously established Nature Relatedness-anxiety relationship.

    Full Text Available Background This study examines whether associations between activity-related support and adolescents' physical activity differ for adolescents at high versus low risk of physical inactivity. Methods: Participants included 202 middle-school-aged girls (N = 92 and boys (N = 110. Physical activity was assessed using three self-report questionnaires. Activity-related support from mothers, fathers, siblings, and peers was assessed using the Activity Support Scale. Perceived sport competence was assessed using the Physical Activity Self Description Questionnaire. Participants' height and weight were measured and used to calculate their age- and sex-adjusted Body Mass Index percentile. Participants were classified as being at high risk for physical inactivity if they fulfilled two of the following three criteria: (1 overweight; (2 female; or (3 having low perceived sport competence. Results: Activity-related support from all sources was associated with higher levels of physical activity among adolescents. A stronger association between activity support and physical activity was found for adolescents at high risk for physical inactivity in comparison to adolescents at low risk. Conclusions: Findings from this study suggest that the activity-related support from family and friends may be an effective tool in promoting physical activity among youth at risk of physical inactivity.

    Physical and biological seabed impacts can persist long after the cessation of marine aggregate dredging. Whilst small-scale experimental studies have shown that it may be possible to mitigate such impacts, it is unclear whether the costs of restoration are justified on an industrial scale. Here we explore this question using a case study off the Thames Estuary, UK. By understanding the nature and scale of persistent impacts, we identify possible techniques to restore the physical properties of the seabed, and the costs and the likelihood of success. An analysis of the ecosystem services and goods/benefits produced by the site is used to determine whether intervention is justified. Whilst a comparison of costs and benefits at this site suggests restoration would not be warranted, the analysis is site-specific. We emphasise the need to better define what is, and is not, an acceptable seabed condition post-dredging. Crown Copyright © 2013. Published by Elsevier Ltd. All rights reserved.

    The Geophysical Fluid Dynamics Laboratory (GFDL) has developed a coupled general circulation model (CM3) for the atmosphere, oceans, land, and sea ice. The goal of CM3 is to address emerging issues in climate change, including aerosol-cloud interactions, chemistry-climate interactions, and coupling between the troposphere and stratosphere. The model is also designed to serve as the physical system component of earth system models and models for decadal prediction in the near-term future-for example, through improved simulations in tropical land precipitation relative to earlier-generation GFDL models. This paper describes the dynamical core, physical parameterizations, and basic simulation characteristics of the atmospheric component (AM3) of this model. Relative to GFDL AM2, AM3 includes new treatments of deep and shallow cumulus convection, cloud droplet activation by aerosols, subgrid variability of stratiform vertical velocities for droplet activation, and atmospheric chemistry driven by emissions with advective, convective, and turbulent transport. AM3 employs a cubed-sphere implementation of a finite-volume dynamical core and is coupled to LM3, a new land model with ecosystem dynamics and hydrology. Its horizontal resolution is approximately 200 km, and its vertical resolution ranges approximately from 70 m near the earth's surface to 1 to 1.5 km near the tropopause and 3 to 4 km in much of the stratosphere. Most basic circulation features in AM3 are simulated as realistically, or more so, as in AM2. In particular, dry biases have been reduced over South America. In coupled mode, the simulation of Arctic sea ice concentration has improved. AM3 aerosol optical depths, scattering properties, and surface clear-sky downward shortwave radiation are more realistic than in AM2. The simulation of marine stratocumulus decks remains problematic, as in AM2. The most intense 0.2% of precipitation rates occur less frequently in AM3 than observed. The last two decades of

    The internationally favored direction of the physics sciences looks for the solution of the basic problems in higher and higher energies at impressive research constructions - mockingly mentioned as 'cognition machines' - which surpass itself with its financial efforts each the other. If in this wise shall be found: 'The elementariest bit of all elements'' and 'the unity of the whole physics as well as the whole nature sciences at all', then this is a thought aberration. The prognosticated HIGGS-particles may have an exceptional quality; however, they would be very complex objects which integrate an enormous number of effect-quanta h (Planck constants) in their structure: They are with safety not simplicity. They will also not bring a better understanding about the simplicity of the last elements for us. We know since Planck, Poincare, Einstein, Bohr, Heisenberg, Schroedinger, DeBrogue and other well-known physicists that the 'atomos' can have only a diminutiveness discrete not measurable energy. The search with gigantic machines is at all especially nonsensical than it pumps still energy into the processes. However, the elementary consists of fractions from that energy what have well-known smallest particles or weakest radiation in itself puts. The work in hand follows another approach. It grasps nature on a deductive way. I start out from a most general analysis and synthesis of scientific and everyday-language concepts; and I combine that with a principle of 'general physical field' which after Einstein must exist. The dynamic space-time processes of the fields are depicted by graphic means in mathematical spatial coordinate-systems. Through it arises a consistent view over all areas of the knowledge from the most simply over simple structures until to the most complicated phenomena and things: that one are the cognition remained secretive till now obstinately.

    2011-01-01

    ABSTRACT Purpose: To identify the perceived benefits of and barriers to clinical supervision of physical therapy (PT) students. Method: In this qualitative descriptive study, three focus groups and six key-informant interviews were conducted with clinical physical therapists or administrators working in acute care, orthopaedic rehabilitation, or complex continuing care. Data were coded and analyzed for common ideas using a constant comparison approach. Results: Perceived barriers to supervising students tended to be extrinsic: time and space constraints, challenging or difficult students, and decreased autonomy or flexibility for the clinical physical therapists. Benefits tended to be intrinsic: teaching provided personal gratification by promoting reflective practice and exposing clinical educators to current knowledge. The culture of different health care institutions was an important factor in therapists' perceptions of student supervision. Conclusions: Despite different disciplines and models of supervision, there is considerable synchronicity in the issues reported by physical therapists and other disciplines. Embedding the value of clinical teaching in the institution, along with strong communication links among academic partners, institutions, and potential clinical faculty, may mitigate barriers and increase the commitment and satisfaction of teaching staff.

    Basic Electromagnetism and Materials is the product of many years of teaching basic and applied electromagnetism. This textbook can be used to teach electromagnetism to a wide range of undergraduate science majors in physics, electrical engineering or materials science. However, by making lesser demands on mathematical knowledge than competing texts, and by emphasizing electromagnetic properties of materials and their applications, this textbook is uniquely suited to students of materials science. Many competing texts focus on the study of propagation waves either in the microwave or optical domain, whereas Basic Electromagnetism and Materials covers the entire electromagnetic domain and the physical response of materials to these waves. Professor André Moliton is Director of the Unité de Microélectronique, Optoélectronique et Polymères (Université de Limoges, France), which brings together three groups studying the optoelectronics of molecular and polymer layers, micro-optoelectronic systems for teleco...

    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." © 2011 John Wiley & Sons A/S.

    The aim of this study was to investigate alterations in physical fitness and anthropometric parameters as well as depression symptoms among the elderly after participation in the "National Walking Program" (Portugal). The sample consisted of 26 elderly people over six months with a total of 72 exercise sessions. The exercise sessions consisted of aerobics (walking and running) and strength and flexibility exercises. Participants were assessed pre- and post-intervention for physical fitness with the Rikli & Jones test. The anthropometric measurements were assessed with a bioimpedance scale and a stadiometer, and depression with Yesavage's Geriatric Depression Scale. Physical activity was only assessed with an accelerometer at the pre-intervention phase. For statistical analysis, the student t test for paired samples was performed using SPSS 21 software. Statistically significant improvements were found in depressive symptoms (p ≤ 0.001), and in all physical fitness tests (p ≤ 0.05) except for flexibility tests (p ≥ 0.05). Waist circumference reduction also showed the positive effects of the intervention (p = 0.031). The conclusion drawn is that participation in the "National Walking Program" for 6 months was effective in improving the physical and psychological health of the elderly.

    Partnerships between school districts and community-based organizations to share school facilities during afterschool hours can be an effective strategy for increasing physical activity. However, the perceived cost of shared use has been noted as an important reason for restricting community access to schools. This study examined shared use of middle school facilities, the amount and type of afterschool physical activity programs provided at middle schools together with the costs of operating the facilities. Afterschool programs were assessed for frequency, duration, and type of structured physical activity programs provided and the number of boys and girls in each program. School operating costs were used to calculate a cost per student and cost per building square foot measure. Data were collected at all 30 middle schools in a large school district over 12 months in 2010-2011. Policies that permitted more use of school facilities for community-sponsored programs increased participation in afterschool programs without a significant increase in operating expenses. These results suggest partnerships between schools and other community agencies to share facilities and create new opportunities for afterschool physical activity programs are a promising health promotion strategy. © 2014, American School Health Association.

    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...

    2012-01-01

    Full Text Available Over the last 30 years the combination of both a sedentary lifestyle and excessive food availability has led to a significant increase in the prevalence of obesity and aggravation of rates of metabolic syndrome and type 2 diabetes mellitus (T2DM. Several lines of scientific evidence have been demonstrating that a low level of physical activity and decreased daily energy expenditure leads to the accumulation of visceral fat and, consequently, the activation of the oxidative stress/inflammation cascade, which underlies the development of insulin resistant T2DM and evolution of micro, and macrovascular complications. This paper focuses on the pathophysiological pathways associated with the involvement of oxidative stress and inflammation in the development of T2DM and the impact of regular physical exercise (training as a natural antioxidant and anti-inflammatory strategy to prevent evolution of T2DM and its serious complications.

    The literature suggests that a fetus will adapt to surrounding adversities by optimizing its use of energy to improve survival, ultimately leading to the programming of the individual's energy intake and expenditure. While recent reviews focused on the fetal programming of energy intake and food preferences, there is also some evidence that fetal adversity is associated with diminished physical activity levels. Therefore, we aimed to review (a) the evidence for an association between being born with intrauterine growth restriction and sedentarism over the life-course and (b) the potential benefits of physical activity over cardiometabolic risk factors for this population. PubMed, Scielo, Scopus and Embase. Most clinical studies that used objective measures found no association between intrauterine growth restriction and physical activity levels, while most studies that used self-reported questionnaires revealed such relationships, particularly leisure time physical activity. Experimental studies support the existence of fetal programming of physical activity, and show that exposure to exercise during IUGR individuals' life improves metabolic outcomes but less effect was seen on muscle architecture or function. Alterations in muscle strength and metabolism, as well as altered aerobic performance, may predispose IUGR individuals to be spontaneously less physically active, suggesting that this population may be an important target for preventive interventions. Although very heterogeneous, the different studies allow us to infer that physical activity may have beneficial effects especially for individuals that are more vulnerable to metabolic modifications such as those with IUGR.

    Full Text Available AimMillions of people die each year due to cardiovascular disease (CVD. A Western lifestyle not only fuses a significant intake of fat with physical inactivity and obesity but also promotes CVD. Recent evidence suggests that dietary fat intake impairs the benefits of physical training. We investigated whether aerobic training could reverse the adverse effects of a high-fat diet (HFD on the aorta. Then, we explored whether this type of exercise could reverse the damage to the heart that is imposed by fat-enriched diet (FED.MethodsRats were randomly assigned to two experiments, which lasted 8 weeks each. First, rats swam for 60 min and were fed either a regular diet [standard diet (STD] or an HFD. After aortic samples had been collected, the rats underwent a histopathological analysis for different biomarkers. Another experiment subjected rats that were fed either an STD or an FED to swimming for 20 or 90 min.ResultsThe first experiment revealed that rats that were subjected to an HFD-endured increased oxidative damage in the aorta that exercises could not counteract. Together with increased cyclooxygenase 2 expression, an HFD in combination with physical training increased the number of macrophages. A reduction in collagen fibers with an increased number of positive α-actin cells and expression of matrix metalloproteinase-2 occurred concomitantly. Upon analyzing the second experiment, we found that physically training rats that were given an FED for 90 min/day decreased the cardiac adipose tissue density, although it did not protect the heart from fat-induced oxidative damage. Even though the physical training lowered cholesterol levels that were promoted by the FED, the levels were still higher than those in the animals that were given an STD. Feeding rats an FED impaired the swimming protocol’s effects on lowering triglyceride concentration. Additionally, exercise was unable to reverse the fat-induced deregulation in hepatic

    Intense physical exercise provoke muscle damage, that in sedentary people can increase cardiovascular risk. Phlebodium decumanum (PD) has shown to have immunomodulator effects in models of moderate intense physical activities in well conditioned groups. To evaluate the PD effects during eccentric exercise, as a model of muscle inflammation protocol, on a sedentary population with cardiovascular risk. This is an experimental, double-blind, multigroup randomized study. Experimental Group 1 (n = 17)received PD, 9 doses of 400 mg (total amount 3.6 g) every 8 hours during 3 days, and Control Group 2 (n = 16)received a placebo. All the subjects performed two treadmill ergoespirometry tests: first, a modified Bruce protocol to discard ischemic responses during exercise and to evaluate VO2max before the experimental phase;and second, with an eccentric protocol (14% descending ramp test) during 10 minutes in stable state at 70-80%VO2max, as experimental inflammatory protocol.We compared intra and inter groups to evaluate differences in the pre and post-test differences results on blood muscle damage variables. The study shown statistically significant differences in all pre-post intra-groups results in muscle damage variables (CK, LDH and Myoglobin, but not in Cardiac Troponin), and in functional lower-limb test (SJand CMJ). The comparison of inter-group results shown less muscle damage and less functional lower-limb deterioration in Group 1 compared with Control group, with statistical significance in both cases. Differences in handgrip dynamometry were no statistically significant. The eccentric exercise protocol in that study has proven to be a good model to induce muscle and functional damage in sedentary people. Short PD treatment has shown to reduce muscle and functional acute damages compared with placebo control group in this specific population. Copyright AULA MEDICA EDICIONES 2014.

    Infants with Prader-Willi syndrome (PWS) typically display failure to thrive and decreased muscle mass with excess body fat for age. Growth hormone (GH) therapy in children with PWS improves, but does not normalize, body composition and muscle strength and agility. The objective of this study was to determine the effects of earlier GH therapy on anthropometric measurements, body composition, and psychomotor development in affected PWS infants and toddlers. Twenty-five subjects, ages 4-37 months, were randomized to 2 years of GH therapy (1 mg/m(2)/day) or 1 year of observation without GH treatment and then placed on GH (1.5 mg/m(2).day) for 1 year only. Anthropometric measurements were obtained by standard methods: percent body fat, lean body mass, and total body bone mineral density by dual x-ray absorptiometry; motor constructs of mobility and stability by the Toddler Infant Motor Evaluation; and cognitive and language function by the Capute Scales of Infant Language and Cognitive Development. GH-treated PWS subjects demonstrated normalization of length/height standard deviation scores (SDS), faster head growth, increased lean body mass accrual, and decreased percent body fat (P < 0.005 for all parameters), as well as improved language (P = 0.05) and cognitive (P = 0.02) quotient Z-scores compared with similarly aged untreated PWS subjects after 1 year into the study. PWS subjects treated before their first birthday spoke their first words at a mean age of 14.4 +/- 2.8 months and walked independently at 23.3 +/- 4.8 months. GH therapy was well-tolerated; however, one PWS subject experienced scoliosis progression. As greater benefits were seen in our study with early treatment, prompt referral to a pediatric endocrinologist for consideration of GH therapy is recommended for PWS at an early age.

    Evidence is lacking on whether health-benefiting community-based interventions differ in their effectiveness according to socioeconomic characteristics. We evaluated whether the benefit of a structured physical activity intervention on reducing mobility disability in older adults differs by education or income. The Lifestyle Interventions and Independence for Elders (LIFE) study was a multicentre, randomised trial that compared a structured physical activity programme with a health education programme on the incidence of mobility disability among at-risk community-living older adults (aged 70-89 years; average follow-up of 2.6 years). Education (≤ high school (0-12 years), college (13-17 years) or postgraduate) and annual household income were self-reported (education (0.72, 0.51 to 1.03; N=411) compared with lower education (high school or less (0.93, 0.70 to 1.24; N=536). However, the education group×intervention interaction term was not statistically significant (p=0.54). Findings were in the same direction yet less pronounced when household income was used as the socioeconomic indicator. In the largest and longest running trial of physical activity amongst at-risk older adults, intervention effect sizes were largest among those with higher education or income, yet tests of statistical interactions were non-significant, likely due to inadequate power.

    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.

  9. Who cares about physics today? A marketing strategy for the survival of fundamental science and the benefit of society

    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 research programs under the cognizance of the Office of Energy Research (OER) are directed toward discovery of natural laws and new knowledge, and to improved understanding of the physical and biological sciences as related to the development, use, and control of energy. The ultimate goal is to develop a scientific underlay for the overall DOE effort and the fundamental principles of natural phenomena so that these phenomena may be understood, and new principles, formulated. The DOE-OER outlay activities include three major programs: High Energy Physics, Nuclear Physics, and Basic Energy Sciences. Taken together, these programs represent some 30 percent of the Nation's Federal support of basic research in the energy sciences. The research activities of OER involve more than 6,000 scientists and engineers working in some 17 major Federal Research Centers and at more than 135 different universities and industrial firms throughout the United States. Contract holders in the areas of high-energy physics, nuclear physics, materials sciences, nuclear science, chemical sciences, engineering, mathematics geosciences, advanced energy projects, and biological energy research are listed.

    We evaluated the cost-effectiveness of the Give-it-a-Go programme, which offers free leisure centre memberships to physically inactive members of the public in a single London Borough receiving state benefits. A decision analytic Markov model was developed to analyse lifetime costs and quality-adjusted life-years (QALYs) of 1025 people recruited to the intervention versus no intervention. In the intervention group, people were offered 4 months of free membership at a leisure centre. Physical activity levels were assessed at 0 and 4 months using the International Physical Activity Questionnaire (IPAQ). Higher levels of physical activity were assumed to decrease the risk of coronary heart disease, stroke and diabetes mellitus type II, as well as improve mental health. Costs were assessed from a National Health Service (NHS) perspective. Uncertainty was assessed using one-way and probabilistic sensitivity analyses. One-hundred fifty nine participants (15.5 %) completed the programme by attending the leisure centre for 4 months. Compared with no intervention, Give it a Go increased costs by £67.25 and QALYs by 0.0033 (equivalent to 1.21 days in full health) per recruited person. The incremental costs per QALY gained were £20,347. The results were highly sensitive to the magnitude of mental health gain due to physical activity and the duration of the effect of the programme (1 year in the base case analysis). When the mental health gain was omitted from the analysis, the incremental cost per QALY gained increased to almost £1.5 million. In the probabilistic sensitivity analysis, the incremental costs per QALY gained were below £20,000 in 39 % of the 5000 simulations. Give it a Go did not significantly increase life-expectancy, but had a positive influence on quality of life due to the mental health gain of physical activity. If the increase in physical activity caused by Give it a Go lasts for more than 1 year, the programme would be cost-effective given a

    Full Text Available Purpose: to reveal modern ideas about the essence of the concept of "sport" and determine its role in the development of the general theory of physical culture and sports theory. Material & Methods: analysis of specialized literature, which highlights various aspects of the development of the field of people's activities related to the use of physical exercises. Results: in today's society there is an objective sphere of human activity related to the use of physical exercises, for which the name in domestic and foreign scientific and social practice is most often used the term "physical culture". Conclusion: the constitutive conditions of the process of developing a general theory of physical culture are singled out, it is shown that sport, as a special socio-cultural phenomenon, is a historically conditioned activity of people associated with the use of physical exercises, aimed at preparing and participating in competitions, as well as individual and socially significant results of such activity.

    Ettekal, Idean; Ladd, Gary W

    2015-12-01

    This study examined the associations between children's co-occurring relational and physical aggression trajectories and their peer relations (i.e., peer rejection, peer acceptance, and reciprocated friendships) from late childhood (Grade 4; Mage = 10.0) to early adolescence (Grade 8; Mage = 13.9). Using a sample of 477 children (240 girls), the findings indicated there were multiple heterogeneous subgroups of children who followed distinct co-occurring aggression trajectories. For each of these subgroups, multiple indices of their relational development were assessed and findings revealed notable group differences. These results have implications about the potential costs and benefits of aggression, and how its associations with children's peer relationships may vary as a function of aggression subtype, developmental timing, and gender.

    Over the last decades, more and more evidence is accumulated that physical activity (PA) and exercise interventions are essential components in primary and secondary prevention for cardiovascular disease. However, it is less clear whether and which type of PA and exercise intervention (aerobic exercise, dynamic resistive exercise, or both) or characteristic of exercise (frequency, intensity, time or duration, and volume) would yield more benefit in achieving cardiovascular health. The present paper, as the first of a series of three, will make specific recommendations on the importance of these characteristics for cardiovascular health in the population at large. The guidance offered in this series of papers is aimed at medical doctors, health practitioners, kinesiologists, physiotherapists and exercise physiologists, politicians, public health policy makers, and the individual member of the public. Based on previous and the current literature, recommendations from the European Association on Cardiovascular Prevention and Rehabilitation are formulated regarding type, volume, and intensity of PA and exercise.

  16. Is the Belief in Meritocracy Palliative for Members of Low Status Groups? Evidence for a Benefit for Self-Esteem and Physical Health via Perceived Control

    Consensually held ideologies may serve as the cultural “glue” that justifies hierarchical status differences in society (e.g. Augustinos, 1998). Yet to be effective these beliefs need to be embraced by low-status groups. Why would members of low-status groups endorse beliefs that justify their relative disadvantage? We propose that members of low-status groups in the United States may benefit from some system-justifying beliefs (such as the belief in meritocracy) to the extent that these beliefs emphasize the perception of control over future outcomes. In 2 studies, among women, lower-SES women, and women of color, we found a positive relationship between the belief in meritocracy and well-being (self-esteem and physical health) that was mediated by perceived control. Members of low-status groups may benefit from some system-justifying beliefs to the extent that these beliefs, like the belief in meritocracy, emphasize the perception of control over future outcomes.

    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). The major event of the past three months was the first “Physics/Trigger week” in Apri...

  18. From basic needs to basic rights.

    Science.gov (United States)

    Facio, A

    1995-06-01

    After arriving at an understanding that basic rights refer to all human needs, it is clear that a recognition of the basic needs of female humans must precede the realization of their rights. The old Women in Development (WID) framework only understood women's needs from an androcentric perspective which was limited to practical interests. Instead, women's primary need is to be free from their subordination to men. Such an understanding places all of women's immediate needs in a new light. A human rights approach to development would see women not as beneficiaries but as people entitled to enjoy the benefits of development. Discussion of what equality before the law should mean to women began at the Third World Conference on Women in Nairobi where the issue of violence against women was first linked to development. While debate continues about the distinction between civil and political rights and economic, social, and cultural rights, the realities of women's lives do not permit such a distinction. The concept of the universality of human rights did not become codified until the UN proclaimed the Universal Declaration of Human Rights in 1948. The declaration has been criticized by feminists because the view of human rights it embodies has been too strongly influenced by a liberal Western philosophy which stresses individual rights and because it is ambiguous on the distinction between human rights and the rights of a citizen. The protection of rights afforded by the Declaration, however, should not be viewed as a final achievement but as an ongoing struggle. International conferences have led to an analysis of the human-rights approach to sustainable development which concludes that women continue to face the routine denial of their rights. Each human right must be redefined from the perspective of women's needs, which must also be redefined. Women must forego challenging the concept of the universality of human rights in order to overcome the argument of cultural

    The importance of teaching materials in accordance with the characteristics of students became the main reason for the development of basic electronics I module integrated character values based on conceptual change teaching model. The module development in this research follows the development procedure of Plomp which includes preliminary research, prototyping phase and assessment phase. In the first year of this research, the module is validated. Content validity is seen from the conformity of the module with the development theory in accordance with the demands of learning model characteristics. The validity of the construct is seen from the linkage and consistency of each module component developed with the characteristic of the integrated learning model of character values obtained through validator assessment. The average validation value assessed by the validator belongs to a very valid category. Based on the validator assessment then revised the basic electronics I module integrated character values based on conceptual change teaching model.

    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. Since then, the accumulated integrated luminosity has increased by a factor of more than 100, and all groups have been working tremendously hard on analysing this dataset.

    Full Text Available Purpose : The questions about the importance of physical fitness of young players to improve the management and correction of the training process. Material : In the research participated 40 players aged 16-17 years of specialized youth football school of FC "Obolon-Brewery". Data for the study of physical fitness were teacher observations and teacher testing carried out under the direct training of young players. Results : It is shown that the structure of physical fitness among all the studied parameters there is a close correlation relationship, except for a parameter that characterizes the start speed. It was found that the above regularities indicate the advisability of excluding the studied parameters in the structure of physical fitness of young players to improve the efficiency of the training process at the base of specialized training. Conclusions : It is recommended to improve the starting speed to use non-gaming and technical and tactical exercises.

    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. © 2016. All rights reserved.

    This script contains theses for an universal 'Spiral-Field-Theory' that are capable to dissolve problems in parallel from different areas which are far from each other. Starting point is the stuck principle discussion about the relationships between the Classic Physics and the Quantum Physics. Aim is the clarification of questions which remained open. In 1925 Max Planck had formulated as follows: 'The research of physics can not rest, so long not has been together-welded: on the one hand the mechanics and the electrodynamics with on the other hand the lesson of the stationary one and the radiating heat to a sole unitary theory'. The Spiral-Field-Model develops a supporting structure from General Field into which they will class the secure knowledge from experiments and well-proved theories. The most important thing of this new Final Theory is the detailed generating of all nature courses of phenomena exclusively from radiation and that in the direct meaning of the word. In the final effect the two great disciplines of the physics which are drifted from each other, become bonded together to a super ordinate theoretical building of the nature sciences. (orig.)

    While the responsibility for nuclear security at the national level rests entirely with each state, international co-operation can be crucial in helping states to fulfil their nuclear security responsibilities and obligations. The central role of the International Atomic Energy Agency (IAEA) in strengthening the nuclear security framework and leading the co-ordination of international activities in the field of nuclear security is now widely recognised. Although much has been done to help states in improving nuclear security, by and under the auspices of the IAEA and other intergovernmental organisations, nuclear terrorism has gained a global recognition as one of the most challenging threats to global security in the 21. century Reports by IAEA member states to the IAEA's Incident and Trafficking Database (ITDB) indicate that nuclear material continues to go missing. Also, too many nuclear facilities are still inadequately protected and sabotage thereof is a threat. Border security remains lax in too many places and the possibility for nuclear smuggling may exist. Attempts by individuals and groups of persons are still made to acquire nuclear material for terrorist and other malicious purposes. The threat of nuclear terrorism remains real. Adopted under the auspices of the IAEA on 8 July 2005, the Amendment to the Convention on the Physical Protection of Nuclear Material ('Amendment') and the existing convention, the Convention on the Physical Protection of Nuclear Material (CPPNM or 'Convention') of 1980, are one of a number of treaties comprising the international legal framework on nuclear security. As will be explained later in the article, the Amendment expands and deepens the effect of the CPPNM. However, more than nine years after its adoption and despite the perceived threat and recognised need to strengthen the CPPNM dating back some 15 years ago, the Amendment is still not in force. Although to some CPPNM states parties, the pressing need for the

    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”). All this was planned in the context of the beginning of a ramp down of these Monte Carlo efforts, in anticipation of data.  The ICHEP days are described below (agenda and talks at: http://indic...

    There have been two plenary physics meetings since the December CMS week. The year started with two workshops, one on the measurements of the Standard Model necessary for “discovery physics” as well as one on the Physics Analysis Toolkit (PAT). Meanwhile the tail of the “2007 analyses” is going through the last steps of approval. It is expected that by the end of January all analyses will have converted to using the data from CSA07 – which include the effects of miscalibration and misalignment. January Physics Days The first Physics Days of 2008 took place on January 22-24. The first two days were devoted to comprehensive re¬ports from the Detector Performance Groups (DPG) and Physics Objects Groups (POG) on their planning and readiness for early data-taking followed by approvals of several recent studies. Highlights of POG presentations are included below while the activities of the DPGs are covered elsewhere in this bulletin. January 24th was devo...

    Defined as the scientific study of matter and energy, physics explains how all matter behaves. Separated into modern and classical physics, the study attracts both experimental and theoretical physicists. From the discovery of the process of nuclear fission to an explanation of the nature of light, from the theory of special relativity to advancements made in particle physics, this volume profiles 10 pioneers who overcame tremendous odds to make significant breakthroughs in this heavily studied branch of science. Each chapter contains relevant information on the scientist''s childhood, research, discoveries, and lasting contributions to the field and concludes with a chronology and a list of print and Internet references specific to that individual.

    The time period between the last CMS week and this June was one of intense activity with numerous get-together targeted at addressing specific issues on the road to data-taking. The two series of workshops, namely the “En route to discoveries” series and the “Vertical Integration” meetings continued.   The first meeting of the “En route to discoveries” sequence (end 2007) had covered the measurements of the Standard Model signals as necessary prerequisite to any claim of signals beyond the Standard Model. The second meeting took place during the Feb CMS week and concentrated on the commissioning of the Physics Objects, whereas the third occurred during the April Physics Week – and this time the theme was the strategy for key new physics signatures. Both of these workshops are summarized below. The vertical integration meetings also continued, with two DPG-physics get-togethers on jets and missing ET and on electrons and photons. ...

    The months that have passed since the last CMS Bulletin have been a very busy and exciting time for CMS physics. We have gone from observing the very first 8TeV collisions produced by the LHC to collecting a dataset of the collisions that already exceeds that recorded in all of 2011. All in just a few months! Meanwhile, the analysis of the 2011 dataset and publication of the subsequent results has continued. These results come from all the PAGs in CMS, including searches for the Higgs boson and other new phenomena, that have set the most stringent limits on an ever increasing number of models of physics beyond the Standard Model including dark matter, Supersymmetry, and TeV-scale gravity scenarios, top-quark physics where CMS has overtaken the Tevatron in the precision of some measurements, and bottom-quark physics where CMS made its first discovery of a new particle, the Ξ*0b baryon (candidate event pictured below).

    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). Most of the results are based on the full 2010 pp data sample, which corresponds to 36 pb-1 at √s = 7 TeV.

Changes in motivational regulations as predictors of subsequent change in light and moderate-to-vigorous physical activity (PA) and affect were also examined. Women [n = 150; M(age) = 54.41 (SD = 10.87) years] completed self-report questionnaires and wore an accelerometer for 7 days at Time 1 [M = 3.94 (SD = 3.08) months following primary treatment], as well as 3 (Time 2) and 6 (Time 3) months later. Data were analyzed using repeated-measures analysis of variance and path analysis using residual change scores. Identified regulation and self-determined motivation (i.e., combined intrinsic motivation and identified regulation) scores decreased over time (p positive affect (β = -0.16), ΔTime(1-2) in introjected (β = 0.25) and amotivation (β = 0.19) were related to ΔTime(2-3) in negative affect, and ΔTime(1-2) in self-determined motivation was related to ΔTime(2-3) in positive affect (β = 0.40) and moderate-to-vigorous PA (β = 0.21). Changes in motivational regulations were related to changes in PA and affect in the aftermath of breast cancer. Given the benefits of self-determined motivation, additional research is needed to develop and test interventions aimed at enhancing this type of motivation. Copyright © 2013 John Wiley & Sons, Ltd.

    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. These analyses could not have happened without the dedicated work of the full collaboration on building and commissioning the detector, computing, and software systems combined with the tireless work of many to collect, calibrate and understand the data and our detector.

    Physics-wise, the CMS week in December was dominated by discussions of the analyses that will be carried out in the “next six months”, i.e. while waiting for the first LHC collisions.  As presented in December, analysis approvals based on Monte Carlo simulation were re-opened, with the caveat that for this work to be helpful to the goals of CMS, it should be carried out using the new software (CMSSW_2_X) and associated samples.  By the end of the week, the goal for the physics groups was set to be the porting of our physics commissioning methods and plans, as well as the early analyses (based an integrated luminosity in the range 10-100pb-1) into this new software. Since December, the large data samples from CMSSW_2_1 were completed. A big effort by the production group gave a significant number of events over the end-of-year break – but also gave out the first samples with the fast simulation.

This has resulted in the submission of 16 papers already, including nine on the search for the Higgs boson. In addition, a number of preliminary results on the 2011 dataset have been released to the public. The Exotica and SUSY groups approved several searches for new physics in January, such as searches for W′ and exotic highly ionising particles.

      The period since the last CMS Bulletin has been historic for CMS Physics. 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...

    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.

    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.

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.

Advances in X-ray tubes, detection technologies and image reconstruction methods led to the development of multiple-row detector CT (MDCT) technologies in early 2000, that has been the impetus for new fields such as Cardiovascular CT, Hybrid CT (PET-CT and SPECT-CT), CT Perfusion, Cone Beam CT, etc. It is now possible to image the entire organ (such as heart) in less than 0.3 seconds providing isotropic resolution images with high temporal resolution. With all X-ray imaging modalities, including CT, the concern is the radiation dose. Since CT procedures are one of the major imaging procedures performed in any hospital, it is important to optimize CT protocols in order to provide quality images at optimal radiation dose

  17. Basic standards for radiation protection

    International Nuclear Information System (INIS)

    Webb, G.A.M.

    1982-01-01

    The basic standards for radiation protection have been based, for many years, on the recommendations of the International Commission of Radiological Protection. The three basic standards recommended by the Commission may be summarized as ''justification, optimization of protection and adherence to dose limitations. The applications of these basic principles to different aspects of protection are briefly summarized and the particular ways in which they have been applied to waste described in more detail. The application of dose limits, both in the control of occupational exposure and in regulating routine discharges of radioactive effluents is straight forward in principle although the measurement and calculational requirements may be substantial. Secondary standards such as derived limits may be extremely useful and the principles underlying their derivation will be described. Optimization of protection is inherently a more difficult concept to apply in protection and the various techniques used will be outlined by with particular emphasis on the use of cost benefit analysis are recommended by the ICRP. A review will be given of the problems involved in extending these basic concepts of the ICRP to probabilistic analyses such as those required for assessing the consequences of accidents or disruptive events in long term repositories. The particular difficulties posed by the very long timescales involved in the assessment of waste management practices will be discussed in some detail. (orig./RW)

    CERN Document Server

    Newman, Jay

    2008-01-01

    Originally developed for the author's course at Union College, this text is designed for life science students who need to understand the connections of fundamental physics to modern biology and medicine. Almost all areas of modern life sciences integrally involve physics in both experimental techniques and in basic understanding of structure and function. Physics of the Life Sciences is not a watered-down, algebra-based engineering physics book with sections on relevant biomedical topics added as an afterthought. This authoritative and engaging text, which is designed to be covered in a two-semester course, was written with a thoroughgoing commitment to the needs and interests of life science students. Although covering most of the standard topics in introductory physics in a more or less traditional sequence, the author gives added weight and space to concepts and applications of greater relevance to the life sciences. Students benefit from occasional sidebars using calculus to derive fundamental relations,...

    Pitacco, Ermanno

    2014-01-01

    Health Insurance aims at filling a gap in actuarial literature, attempting to solve the frequent misunderstanding in regards to both the purpose and the contents of health insurance products (and ‘protection products’, more generally) on the one hand, and the relevant actuarial structures on the other. In order to cover the basic principles regarding health insurance techniques, the first few chapters in this book are mainly devoted to the need for health insurance and a description of insurance products in this area (sickness insurance, accident insurance, critical illness covers, income protection, long-term care insurance, health-related benefits as riders to life insurance policies). An introduction to general actuarial and risk-management issues follows. Basic actuarial models are presented for sickness insurance and income protection (i.e. disability annuities). Several numerical examples help the reader understand the main features of pricing and reserving in the health insurance area. A short int...

    To examine vitamin D status and its association with physical performance and muscle mass in older Chinese men. Cross-sectional and prospective cohort study design. Hong Kong, People's of Republic of China. Nine hundred thirty-nine community-dwelling men aged 65 and older for cross-sectional analysis and 714 for longitudinal analysis. Baseline serum 25-hydroxyvitamin D (25OHD) was measured using a competitive radioimmunoassay kit. Baseline and 4-year physical performance measures (grip strength, 6-m walking speed, step length in a 6-m walk, time to complete five chair stands) were measured, and appendicular skeletal muscle mass (ASM) was assessed using dual-energy X-ray absorptiometry. Data were collected for confounding factors: demographic, number of diseases, smoking, alcohol use, body mass index, physical activity, diet, season of blood sampling, and serum parathyroid hormone (PTH) level. Multivariate regression analyses were performed with adjustments for confounding factors. Mean ± standard deviation serum 25OHD level of this sample of Chinese community-dwelling older men who had a high level of baseline physical function was 77.9 ± 20.5 nmol/L; 94.1% of participants had serum 25OHD levels of 50 nmol/L or greater. Median (interquartile range) serum PTH level was 4.1 pmol/L (3.1-5.5 pmol/L). After adjustment for potential confounding factors, serum 25OHD levels were not associated with baseline or 4-year change in physical performance measures and ASM. In Chinese older men who are vitamin D replete and have a high level of baseline physical function, vitamin D may not have an important role in physical function and muscle mass. © 2012, Copyright the Authors Journal compilation © 2011, The American Geriatrics Society.

    The internationally favored direction of the physics sciences looks for the solution of the basic problems in higher and higher energies at impressive research constructions - mockingly mentioned as 'cognition machines' - which surpass itself with its financial efforts each the other. If in this wise shall be found: 'The elementariest bit of all elements' and 'the unity of the whole physics as well as the whole nature sciences at all', then this is a thought aberration. The prognosticated HIGGS-particles may have an exceptional quality; however, they would be very complex objects which integrate an enormous number of effect-quanta h (Planck constants) in their structure: They are with safety not simplicity. They will also not bring a better understanding about the simplicity of the last elements for us. We know since Planck, Poincare, Einstein, Bohr, Heisenberg, Schroedinger, DeBrogue and other well-known physicists that the 'atomos' can have only a diminutiveness discrete not measurable energy. The search with gigantic machines is at all especially nonsensical than it pumps still energy into the processes. However, the elementary consists of fractions from that energy what have well-known smallest particles or weakest radiation in itself puts. The work in hand follows another approach. It grasps nature on a deductive way. I start out from a most general analysis and synthesis of scientific and everyday-language concepts; and I combine that with a principle of 'general physical field' which after Einstein must exist. The dynamic space-time processes of the fields are depicted by graphic means in mathematical spatial coordinate-systems. Through it arises a consistent view over all areas of the knowledge from the most simply over simple structures until to the most complicated phenomena and things: that one are the cognition remained secretive till now obstinately. In the foreground will be originate as important the

    Effect materials derive their color and effect primarily from thin-film interference. Effect materials have evolved over the decades from simple guanine crystals to the complex multilayer optical structures of today. The development of new complex effect materials requires an understanding of the optics of effect materials. Such an understanding would also benefit the cosmetic formulator as these new effect materials are introduced. The root of this understanding begins with basic optics. This paper covers the nature of light, interference of waves, thin-film interference, color from interference, and color travel.

  9. Basic mechanisms of urgency: roles and benefits of pharmacotherapy.

    2009-12-01

    Since urgency is key to the overactive bladder syndrome, we have reviewed the mechanisms underlying how bladder filling and urgency are sensed, what causes urgency and how this relates to medical therapy. Review of published literature. As urgency can only be assessed in cognitively intact humans, mechanistic studies of urgency often rely on proxy or surrogate parameters, such as detrusor overactivity, but these may not necessarily be reliable. There is an increasing evidence base to suggest that the sensation of ‘urgency’ differs from the normal physiological urge to void upon bladder filling. While the relative roles of alterations in afferent processes, central nervous processing, efferent mechanisms and in intrinsic bladder smooth muscle function remain unclear, and not necessarily mutually exclusive, several lines of evidence support an important role for the latter. A better understanding of urgency and its causes may help to develop more effective treatments for voiding dysfunction.

  12. 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.

    2012-11-01

    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.
