    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.

    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...

  17. Biopsychosocial Benefits of Physical Activity in Children

    Directory of Open Access Journals (Sweden)

    Ayse Meydanlioglu

    2015-06-01

    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.

  19. Colloidal Plasmas : Basic physics of colloidal plasmas

    Indian Academy of Sciences (India)

    C B Dwivedi

    2000-11-01

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

  20. Basic Physics for Nuclear Medicine. Chapter 1

    International Nuclear Information System (INIS)

    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

  1. Basic Data of Ionized Gas Physics

    International Nuclear Information System (INIS)

    An ionized gas can a priori contain the following types of particle: photons, electrons, atoms, diatomic or polyatomic molecules, atomic or molecular positive ions and atomic or molecular negative ions. A study of the properties of ionized gases must therefore be based on the fundamental data on the interactions between these particles, i.e. elastic or inelastic collision cross-sections and the probability of induced or spontaneous transitions. From these basic data it is possible to calculate theoretically certain elementary macroscopic properties such as ion and electron mobility, diffusion coefficients, Townsend's first coefficient, recombination and attachment coefficients. These results (cross-sections and elementary macroscopic properties) constitute as a body the basic data for the physics of ionized gases. The paper is devoted to these basic data, concentrating on cross-sections, mobilities and diffusion coefficients. Beginning with a brief review of the literature, it consists essentially of tables of suggested numerical values, which the author intends to be used as a basis for discussion. Experts in each of the phenomena are invited to indicate values which seem to them better than those selected, and to fill in, where possible, the gaps in this study. In this way it is hoped that by the next Conference a more precise and more complete collection of data will be available. (author)

  3. 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.

    2009-06-01

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

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

  12. Net-Baryon Physics: Basic Mechanisms

    International Nuclear Information System (INIS)

    How does the fraction of energy carried by the net-baryon, B - anti-B , evolve as a function of the centre-of-mass collisional energy per nucleon, sqrt(s)? In order to answer this question we explore the net-baryon mechanism and it is propose a simple but consistent model for net-baryon production in high energy hadron-hadron, hadron-nucleus and nucleus-nucleus collisions. The model basic ingredients are: valence string formation based on standard PDFs with QCD evolution; and string fragmentation via the Schwinger mechanism. Our model shows that a good description of the main features of net-baryon data is possible in the framework of a simplistic model, with the advantage of making the fundamental production mechanisms manifest. We compare results both with data and existing models. (authors)

    It is well known that, in nuclear collisions, a sizable fraction of the available energy is carried away by baryons. As the baryon number is conserved, the net-baryon $B-\\bar{B}$ retains information on the energy-momentum carried by the incoming nuclei. A simple but consistent model for net-baryon production in high energy hadron-hadron, hadron-nucleus and nucleus-nucleus collisions is presented. The basic ingredients of the model are valence string formation based on standard PDFs with QCD evolution and string fragmentation via the Schwinger mechanism. The results of the model are presented and compared with both data and existing models. These results show that a good description of the main features of net-baryon data is possible on the framework of a simplistic model, with the advantage of making the fundamental production mechanisms manifest.

    With the advance of modern radiation therapy technique, radiation dose conformation and dose distribution have improved dramatically. However, the progress does not completely fulfill the goal of cancer treatment such as improved local control or survival. The discordances with the clinical results are from the biophysical nature of photon, which is the main source of radiation therapy in current field, with the lower linear energy transfer to the target. As part of a natural progression, there recently has been a resurgence of interest in particle therapy, specifically using heavy charged particles, because these kinds of radiations serve theoretical advantages in both biological and physical aspects. The Korean government is to set up a heavy charged particle facility in Korea Institute of Radiological & Medical Sciences. This review introduces some of the elementary physics of the various particles for the sake of Korean radiation oncologists' interest. PMID:22984664

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

    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.

  3. Basic concepts in physics. From the cosmos to quarks

    International Nuclear Information System (INIS)

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

    Urbanisation has a profound effect on both people and the environment, as levels of physical activity decline and many natural ecosystems become lost or degraded. Here we draw on emerging research to examine the role of green spaces in providing a venue for outdoor physical activity, and in enhancing the benefit of a given amount of physical activity for urban residents. We identify critical knowledge gaps, including (1) whether (and for whom) levels of physical activity increase as new green spaces are introduced or old spaces reinvigorated; (2) which characteristics of nature promote physical activity; (3) the extent to which barriers to outdoor physical activity are environmental or social; and (4) whether the benefits of physical activity and experiences of nature accrue separately or synergistically. A clear understanding of these issues will help guide effective investment in green space provision, ecological enhancement and green exercise promotion. PMID:26886475

    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.

  14. Hadron Physics and QCD: Just the Basic Facts

    CERN Document Server

    2015-01-01

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

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

    Directory of Open Access Journals (Sweden)

    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

  17. Quantum physics. Vol. 1. From basics to symmetries and perturbations

    International Nuclear Information System (INIS)

    This two-volume set can be naturally divided into two semester courses, and contains a full modern graduate course in quantum physics. The idea is to teach graduate students how to practically use quantum physics and theory, presenting the fundamental knowledge, and gradually moving on to applications, including atomic, nuclear and solid state physics, as well as modern subfields, such as quantum chaos and quantum entanglement. The book starts with basic quantum problems, which do not require full quantum formalism but allow the student to gain the necessary experience and elements of quantum thinking. Only then does the fundamental Schrodinger equation appear. The author has included topics that are not usually covered in standard textbooks and has written the book in such a way that every topic contains varying layers of difficulty, so that the instructor can decide where to stop. Although supplementary sources are not required, ''Further reading'' is given for each chapter, including references to scientific journals and publications, and a glossary is also provided. Problems and solutions are integrated throughout the text. (orig.)

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

    International Nuclear Information System (INIS)

    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

    We investigate the effect of cryogenic temperature implants on electrical junction stability for ultra shallow junction applications for sub-32 nm technology nodes and beyond. A comprehensive study was conducted to gain physical understanding of the impact of cryogenic temperature implants on dopant-defect interactions. Carborane (C{sub 2}B{sub 10}H{sub 12}) molecule, a potential alternative to monomer boron was implanted in carbon preamorphized silicon substrates at cryogenic implant temperatures. Results indicate implants at cryogenic temperatures increase dopant activation with reduced diffusion, resulting in lower sheet resistance for a lower junction depth. Further, this study emphasizes the benefits of co-implants performed at cryogenic temperatures as alternative to traditional preamorphizing implants.

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

  20. Ultra-high energy physics and standard basic principles

    Directory of Open Access Journals (Sweden)

    Gonzalez-Mestres Luis

    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

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

    International Nuclear Information System (INIS)

    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.

  5. Heavy-ion tumor therapy: Physical and radiobiological benefits

    Science.gov (United States)

    Schardt, Dieter; Elsässer, Thilo; Schulz-Ertner, Daniela

    2010-01-01

    High-energy beams of charged nuclear particles (protons and heavier ions) offer significant advantages for the treatment of deep-seated local tumors in comparison to conventional megavolt photon therapy. Their physical depth-dose distribution in tissue is characterized by a small entrance dose and a distinct maximum (Bragg peak) near the end of range with a sharp fall-off at the distal edge. Taking full advantage of the well-defined range and the small lateral beam spread, modern scanning beam systems allow delivery of the dose with millimeter precision. In addition, projectiles heavier than protons such as carbon ions exhibit an enhanced biological effectiveness in the Bragg peak region caused by the dense ionization of individual particle tracks resulting in reduced cellular repair. This makes them particularly attractive for the treatment of radio-resistant tumors localized near organs at risk. While tumor therapy with protons is a well-established treatment modality with more than 60 000 patients treated worldwide, the application of heavy ions is so far restricted to a few facilities only. Nevertheless, results of clinical phase I-II trials provide evidence that carbon-ion radiotherapy might be beneficial in several tumor entities. This article reviews the progress in heavy-ion therapy, including physical and technical developments, radiobiological studies and models, as well as radiooncological studies. As a result of the promising clinical results obtained with carbon-ion beams in the past ten years at the Heavy Ion Medical Accelerator facility (Japan) and in a pilot project at GSI Darmstadt (Germany), the plans for new clinical centers for heavy-ion or combined proton and heavy-ion therapy have recently received a substantial boost.

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

    Physical abuse in school has lifelong consequences affecting child health and educational achievements. A study was designed to assess the prevalence of physical abuse experienced by pupils in basic-education schools in Aden, Yemen, and to examine the risk factors associated with it. A cross-sectional study covering 1066 pupils in 7th-9th grades from 8 schools in different districts of Aden governorate were randomly selected. Answering an anonymous self-administered questionnaire, 55.7% of pupils reported physical abuse at least once in their school lifetime (73.2% of males versus 26.6% of females). Teachers were the main perpetrators (45.4%). A statistically significant association was found between physical abuse and sex, age group, family type and father's education. Significant predictors of physical abuse on multivariate regression were male sex (OR=7.89) and extended family type (OR=1.36). Physical abuse in basic-education schools requires serious consideration by educational authorities, families and the community at large. PMID:23882958

  20. Have quantum mechanical isolated systems a physical meaning. An essential approximation in basic quantum physics

    International Nuclear Information System (INIS)

    An initial assumption in quantum mechanics is that particles (or subsystems) can be isolated from the physical world but still behave in a realistic fashion. This paper shows that the above assumption is not only naive but it has far reaching consequences. In particular, time-reversibility, microscopic reversibility and time-energy principles must be reinterpreted for real non-isolated systems. Moreover the new interpretation is far more consistent than that presently accepted for isolated systems. (author)

    Full Text Available The self-determination theory is a psychological approach to motivation that focuses on causes and consequences of human behavior regulation. According several authors, this theoretical framework could provide important information about the student’s motivational process to physical education class, however, in Portugal does not exists any instrument to measure the basic psychological needs in this domain. So, the main propose of this study is the preliminary adaptation to physical education contexts of Basic Psychological Needs Exercise Scale (Portuguese version: BPNESp, and determine their initial psychometrics properties through an exploratory factor analysis. This propose was accomplished with a sample of 150 students (n=150 from de 2nd and 3rd CEB, aged from 11 to 16 years (M = 13.39, SD = 1.44 with different levels of sports practice. Results revealed a factorial structure just like the original model (12 items grouped in 3 factors, with 4 items hitch factor and presents acceptable values of validity and reliability. Those findings allow us to conclude, that questionnaire can be used in future investigations to measure the basic psychological needs in physical education.

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

    Science.gov (United States)

    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

    International Nuclear Information System (INIS)

    A short historical fundamental plasma physics development review where the main periods where determined by the physicists enumerated in the title is given. 1. I. Langmuir, who was the first to study experimentally the properties of plasmas, has found the main characteristics of plasma and has determined the conditions of plasma state realization. 2. L.D. Landau was the first to understand the reason of why is gas approximation not applicable for plasma description, but he neglected the self-consistent field and has not achieved his goal. 3. A.A. Vlasov showed the important role of self-consistent field and was the first to obtain the correct equation describing the plasma and also has put the Langmuir experiments on the observation of plasma waves and their dispersion on theoretical basis. 4. N.N. Bogolyubov developed the general method for derivation of the dynamic equations for plasma and showed that in the first approximation with respect to Landau parameter Vlasov equation is correct and the second approximation results in Landau corrective in the Vlasov equation. 5. G.V. Gordeev was the first to show that the acoustic vibration branch differs from the sound in gases, the sound in plasma is isothermal and exists only in nonisothermal plasmas. 6. B.B. Kadomtsev and V.P. Silin showed that undamped modes of ion-acoustic vibrations can exist in plasma and were the first to build the theory of plasma turbulence on the undamped Vlasov modes

    Regular physical exercise provides many health benefits, protecting against the development of chronic diseases, and improving quality of life. Some of the mechanisms by which exercise provides these effects are the promotion of an anti-inflammatory state, reinforcement of the neuromuscular function, and activation of the hypothalamic–pituitary–adrenal (HPA) axis. Recently, it has been proposed that physical exercise is able to modify gut microbiota, and thus this could be another factor by w...

    As part of the Nearby Stars (NStars) Program at Appalachian State University, we are determining the basic physical parameters of G and K giants and subgiants within 40 parsecs of the Sun ( ≈ 170 stars). Stellar radii are being determined using the Infrared Flux Method (IRFM, Blackwell & Lynas-Gray, 1994). Combining the radii with luminosity and parallax data, we are determining the effective temperatures; surface gravity is determined by combining the calculated radii with mass estimates from evolutionary models. Metallicities [M/H] are then determined using the simplex method of Gray et al. (2001).

    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.

    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. PMID:27210584

    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.

    2016-09-01

    Plant diversity loss impairs ecosystem functioning, including important effects on soil. Most studies that have explored plant diversity effects belowground, however, have largely focused on biological processes. As such, our understanding of how plant diversity impacts the soil physical environment remains limited, despite the fundamental role soil physical structure plays in ensuring soil function and ecosystem service provision. Here, in both a glasshouse and a long-term field study, we show that high plant diversity in grassland systems increases soil aggregate stability, a vital structural property of soil, and that root traits play a major role in determining diversity effects. We also reveal that the presence of particular plant species within mixed communities affects an even wider range of soil physical processes, including hydrology and soil strength regimes. Our results indicate that alongside well-documented effects on ecosystem functioning, plant diversity and root traits also benefit essential soil physical properties. PMID:27459206

    2011-01-01

    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.

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

    International Nuclear Information System (INIS)

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

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

    Science.gov (United States)

    Turner, Martin J; Avolio, Alberto P

    2016-08-01

    International guidelines suggest limiting sodium intake to 86-100 mmol/day, but average intake exceeds 150 mmol/day. Participants in physical activities are, however, advised to increase sodium intake before, during and after exercise to ensure euhydration, replace sodium lost in sweat, speed rehydration and maintain performance. A similar range of health benefits is attributable to exercise and to reduction in sodium intake, including reductions in blood pressure (BP) and the increase of BP with age, reduced risk of stroke and other cardiovascular diseases, and reduced risk of osteoporosis and dementia. Sweat typically contains 40-60 mmol/L of sodium, leading to approximately 20-90 mmol of sodium lost in one exercise session with sweat rates of 0.5-1.5 L/h. Reductions in sodium intake of 20-90 mmol/day have been associated with substantial health benefits. Homeostatic systems reduce sweat sodium as low as 3-10 mmol/L to prevent excessive sodium loss. "Salty sweaters" may be individuals with high sodium intake who perpetuate their "salty sweat" condition by continual replacement of sodium excreted in sweat. Studies of prolonged high intensity exercise in hot environments suggest that sodium supplementation is not necessary to prevent hyponatremia during exercise lasting up to 6 hr. We examine the novel hypothesis that sodium excreted in sweat during physical activity offsets a significant fraction of excess dietary sodium, and hence may contribute part of the health benefits of exercise. Replacing sodium lost in sweat during exercise may improve physical performance, but may attenuate the long-term health benefits of exercise. PMID:26841436

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

    CERN Document Server

    Kontur, F J

    2013-01-01

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

In general, studies report an inverse, dose dependent relationship between leisure-time physical activity participation, and mental health outcomes. Studies also show a positive association between maximal aerobic capacity and general well-being. More recent studies have confirmed the positive effects of physical activity participation on cognition, including the treatment and prevention of dementia. The current exercise prescription suggested for the treatment of depression is similar to that recommended to the general population for the development and maintenance of cardiorespiratory fitness. There is also strong evidence from large population level studies that long term physical activity participation reduces the risk of future depressive illness. From the available evidence, it would appear that physical activity performed at a frequency, intensity, and duration which is substantially less than that required for the development and maintenance of cardiorespiratory and muscular fitness in the general population, may afford significant benefits in reducing the risk of future depressive illness. This may be particularly encouraging for people with prior depressive illness, or at high risk of future depressive illness, since this vulnerable population already faces significant barriers to physical activity participation over and above those encountered by the general population.

  16. Physical Activity Associated with Public Transport Use—A Review and Modelling of Potential Benefits

    Directory of Open Access Journals (Sweden)

    2012-07-01

    Full Text Available Active travel, particularly walking and cycling, has been recommended because of the health benefits associated with increased physical activity. Use of public transport generally involves some walking to bus stops or train stations. This paper is a systematic review of how much time is spent in physical activity among adults using public transport. It also explores the potential effect on the population level of physical activity if inactive adults in NSW, Australia, increased their walking through increased use of public transport. Of 1,733 articles, 27 met the search criteria, and nine reported on absolute measures of physical activity associated with public transport. A further 18 papers reported on factors associated with physical activity as part of public transport use. A range of 8–33 additional minutes of walking was identified from this systematic search as being attributable to public transport use. Using “bootstrapping” statistical modelling, if 20% of all inactive adults increased their walking by only 16 minutes a day for five days a week, we predict there would be a substantial 6.97% increase in the proportion of the adult population considered “sufficiently active”. More minutes walked per day, or a greater uptake of public transport by inactive adults would likely lead to significantly greater increases in the adult population considered sufficiently active.

    2016-01-01

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

    We derive the upper and lower limits for the basic physical parameters (mass-radius ratio, anisotropy, redshift and total energy) for arbitrary anisotropic general relativistic matter distributions in the presence of a cosmological constant. The values of these quantities are strongly dependent on the value of the anisotropy parameter (the difference between the tangential and radial pressure) at the surface of the star. In the presence of the cosmological constant, a minimum mass configuration with a given anisotropy does exist. Anisotropic compact stellar-type objects can be much more compact than the isotropic ones, and their radii may be close to their corresponding Schwarzschild radii. Upper bounds for the anisotropy parameter are also obtained from the analysis of the curvature invariants. General restrictions for the redshift and the total energy (including the gravitational contribution) for anisotropic stars are obtained in terms of the anisotropy parameter. Values of the surface redshift parameter greater than two could be the main observational signature for anisotropic stellar-type objects.

    An estimated 1.6 million people die from diarrheal diseases each year due to lack of access to safe water and sanitation, and persons with physical disabilities face additional barriers. In Cambodia, approximately 5% of the population is disabled, presenting substantial obstacles in accessing these basic services. The purpose of this study was twofold: first, to identify the challenges facing persons with physical disabilities in accessing safe household water and basic hygiene in rural Cambodia; and, second, to use these results to generate policy and practice recommendations for the water and sanitation hygiene sector implementing water treatment system interventions in rural settings. Fifteen field interviews were conducted with persons with physical disabilities. Thematic analysis was used to identify six main themes. The results indicated that environmental barriers to access were greater in the workplace than household settings and those persons with disabilities had greater awareness about safe drinking water compared to basic hygiene. Additionally, lack of physical strength, distance to water, and lack of financial means were noted as common access barriers. The findings support ongoing research and offer insight into the particular challenges facing persons with physical disabilities in rural areas in accessing safe drinking water and basic hygiene.

  3. Exaggerated Health Benefits of Physical Fitness and Activity dueto Self-selection.

    Energy Technology Data Exchange (ETDEWEB)

    Williams, Paul T.

    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

    Insidious declines in normal aging are well-established. Emerging evidence suggests that non-pharmacological interventions, specifically cognitive and physical training, may counter diminishing age-related cognitive and brain functions. This randomized trial compared effects of two training protocols: cognitive training (CT) vs. physical training (PT) on cognition and brain function in adults 56-75 years. Sedentary participants (N = 36) were randomized to either CT or PT group for 3 h/week over 12 weeks. They were assessed at baseline-, mid-, and post-training using neurocognitive, MRI, and physiological measures. The CT group improved on executive function whereas PT group's memory was enhanced. Uniquely deploying cerebral blood flow (CBF) and cerebral vascular reactivity (CVR) MRI, the CT cohort showed increased CBF within the prefrontal and middle/posterior cingulate cortex (PCC) without change to CVR compared to PT group. Improvements in complex abstraction were positively associated with increased resting CBF in dorsal anterior cingulate cortex (dACC). Exercisers with higher CBF in hippocampi bilaterally showed better immediate memory. The preliminary evidence indicates that increased cognitive and physical activity improves brain health in distinct ways. Reasoning training enhanced frontal networks shown to be integral to top-down cognitive control and brain resilience. Evidence of increased resting CBF without changes to CVR implicates increased neural health rather than improved vascular response. Exercise did not improve cerebrovascular response, although CBF increased in hippocampi of those with memory gains. Distinct benefits incentivize testing effectiveness of combined protocols to strengthen brain health. PMID:27462210

    Directory of Open Access Journals (Sweden)

    2010-12-01

    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

    The main purpose of this research program is to investigate potential semiconductor materials and their multi-band-gap MQW (multiple quantum wells) structures for high efficiency solar cells for aerospace and commercial applications. The absorption and PL (photoluminescence) spectra, the carrier dynamics, and band structures have been investigated for semiconductors of InP, GaP, GaInP, and InGaAsP/InP MQW structures, and for semiconductors of GaAs and AlGaAs by previous measurements. The barrier potential design criteria for achieving maximum energy conversion efficiency, and the resonant tunneling time as a function of barrier width in high efficiency MQW solar cell structures have also been investigated in the first two years. Based on previous carrier dynamics measurements and the time-dependent short circuit current density calculations, an InAs/InGaAs - InGaAs/GaAs - GaAs/AlGaAs MQW solar cell structure with 15 bandgaps has been designed. The absorption and PL spectra in InGaAsP/InP bulk and MQW structures were measured at room temperature and 77 K with different pump wavelength and intensity, to search for resonant states that may affect the solar cell activities. Time-resolved IR absorption for InGaAsP/InP bulk and MQW structures has been measured by femtosecond visible-pump and IR-probe absorption spectroscopy. This, with the absorption and PL measurements, will be helpful to understand the basic physics and device performance in multi-bandgap InAs/InGaAs - InGaAs/InP - InP/InGaP MQW solar cells. In particular, the lifetime of the photoexcited hot electrons is an important parameter for the device operation of InGaAsP/InP MQW solar cells working in the resonant tunneling conditions. Lastly, time evolution of the hot electron relaxation in GaAs has been measured in the temperature range of 4 K through 288 K using femtosecond pump-IR-probe absorption technique. The temperature dependence of the hot electron relaxation time in the X valley has been measured.

    2016-06-01

    This research applied self-determination theory to examine the degree to which satisfaction of basic psychological needs for autonomy, relatedness, and competence explained the association between socioeconomic status and physical and mental health outcomes, while controlling for age, exercise, and smoking status. This was a survey research study with 513 full-time employees in professions representative of a hierarchal organization. The results of the structural equation model verify that psychological need satisfaction mediates the inverse association between socioeconomic status and physical and mental health. Self-determination theory contributes to understanding the psychosocial roots of the uneven distribution of health across the socioeconomic gradient. PMID:25104782

  1. Basic physics program for a low energy antiproton source in North America

    International Nuclear Information System (INIS)

    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

    Full Text Available This article concerns physical activity (PA in penitentiary institutions, understood as non-rest energetic effort performed by prisoners in their free time. The aim of this study was to determine the personality correlates of PA men serving prison sentences. Questionnaire methods were applied in the studies. One group consisted of men incarcerated in penitentiary institutions (N = 121, who were physically active, and the comparison group were physically inactive prisoners (N = 128 aged from 22 to 55 years old. The study results showed that prisoners regularly participating in programs in the field of physical culture and sports are characterized by higher emotional stability (p < 0.05 and a higher level of extraversion (p < 0.05. However, they do not differ in the level of psychoticism (p = 0.80. This paper is a fragment of larger studies on the psychological correlates of physical activity in penitentiary institutions.

  6. Quantum field theory I: Basics in mathematics and physics. A bridge between mathematicians and physicists

    International Nuclear Information System (INIS)

    This is the first volume of a modern introduction to quantum field theory which addresses both mathematicians and physicists, at levels ranging from advanced undergraduate students to professional scientists. The book bridges the acknowledged gap between the different languages used by mathematicians and physicists. For students of mathematics the author shows that detailed knowledge of the physical background helps to motivate the mathematical subjects and to discover interesting interrelationships between quite different mathematical topics. For students of physics, fairly advanced mathematics is presented, which goes beyond the usual curriculum in physics. (orig.)

    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

    2016-09-01

    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.

  11. The influence of basic physical properties of soil on its electrical resistivity value under loose and dense condition

    International Nuclear Information System (INIS)

    Electrical resistivity technique has become a famous alternative tool in subsurface characterization. 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.

  16. Basic physical and chemical information needed for development of Monte Carlo codes

    International Nuclear Information System (INIS)

    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

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

    Science.gov (United States)

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

    1983-01-01

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

    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.

    2016-01-01

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

    Full Text Available 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.

    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 relevance of UHECR

    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 effect size of d = 0.72. However, while students in the experimental group performed better than their control group peers, they rated their knowledge of the topic lower than the control group ( M post-control = 3.0, M post-experiment = 2.7), leading to further examination of their laboratory journals. Results of this study show that 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.

    Engaging in regular physical activity (PA) is important in maintaining health and increasing the overall quality of life of people living with HIV (PLWH). The deep south of the USA is known for its high rate of sedentary behavior although data on the activity levels and perceptions of the benefits and barriers to exercise in women living with HIV in the deep south are lacking. Understanding the perceived benefits and barriers to exercise can guide the development of PA interventions. We conducted a cross-sectional study to determine the PA levels and perceived benefits and barriers to exercise associated with both age and depression level in a group of HIV+ women living in the deep south. We recruited a total of 50 participants from a cohort site for the Women's Interagency HIV Study. Depression was assessed using the Center for Epidemiological Studies Depression Scale (CES-D) and benefits/barriers to exercise were measured using the Exercise Benefits and Barriers Scale (EBBS). We measured PA both subjectively and objectively using the International Physical Activity Questionnaire (IPAQ) and a Fitbit PA monitor, respectively. Our sample was predominantly African-American (96%) and the mean ±SD age, body mass index, and CES-D score were 42 ± 8.8 years, 36.6 ± 11.5 kg/m(2), and 15.6 ± 11.4, respectively. Both subjective and objective measures of PA indicated that our participants were sedentary. The greatest perceived benefit to exercise was physical performance and the greatest barrier to exercise was physical exertion. Higher overall perceived benefits were reported by women ≥43 years and women reporting higher levels of depression. There was no difference in overall barriers associated with age and depression level, but women with depression felt more fatigued by exercise. The results of this study can be helpful when designing and implementing PA interventions in women living with HIV in the deep south. PMID:27023306

    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 statistical classical mechanics and the quantum mechanics are two developed and well-known theories. The described two theories are known and well studied for a long time. Nevertheless, they contain a number of paradoxes. It forces many scientists to doubt internal consistency of these theories. However the given paradoxes can be resolved within the framework of the existing physics, without introduction of new laws .Further in the paper the paradoxes underlying thermodynamics and the quantum mechanics are discussed. The approaches to solution of these paradoxes are suggested. The first one relies on the influence of the external observer (environment), which disrupts the correlations in the system. The second one is based on the limits of self-knowledge of the system in case of both the external observer and the environment is included in the considered system. The concepts of Observable Dynamics, Ideal Dynamics, and Unpredictable dynamics are introduced. The phenomenon of complex (living) systems is con...

    2016-07-01

    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.

  13. Prebreakdown phenomena in liquids: propagation ‘modes’ and basic physical properties

    Lesaint, O.

    2016-04-01

    Prebreakdown phenomena in liquids (usually called ‘streamers’) were characterized experimentally in a wide range of experimental conditions, liquid nature and additives. The description of these phenomena leads to a complex and frequently confused situation, since their properties widely vary when parameters such as liquid nature or voltage are changed. In this review paper, we try to obtain a more comprehensive presentation of pre-breakdown phenomena in liquids by considering different propagation ‘modes’, which can be recognized in a wide range of liquid nature and experimental conditions. On the basis of experimental results either published previously or original, we will review the main parameters and features able to better characterize these modes, and show their general interest. ‘Positive’ streamers observed in point-plane geometry in non-polar liquids are mainly considered here. Some elements allowing a comparison with water, characterized by a much higher permittivity and conductivity are given. The text is concluded by considerations concerning the different physical processes involved in modes.

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

  19. Effect of basic physical parameters to control plasma meniscus and beam halo formation in negative ion sources

    International Nuclear Information System (INIS)

    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− 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

    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.

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

    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...

    [Purpose] The purpose of the present study was to determine whether there was a correlation between basic physical fitness and pulmonary function in Korean school students, to present an alternative method for improving their pulmonary function. [Subjects and Methods] Two hundred forty healthy students aged 6-17 years performed physical fitness tests of hand-grip strength, sit and reach, Sargent jump, single leg stance, and pulmonary function tests of forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) using a Quark PFT. [Results] Muscle strength and power of boys improved in the late period of elementary school and middle school. Muscle strength of girls improved in the late period of elementary school. Analysis of factors affecting pulmonary function revealed that height, weight, BMI, and body fat significantly correlated with spirometric parameters. Right hand-grip strength, left hand-grip strength, and Sargent jump also significantly correlated with FVC and FEV1. [Conclusion] In order to improve the pulmonary function of children and adolescents, aerobic exercise and an exercise program to increase muscle strength and power is needed, and it should start in the late period of elementary school when muscle strength and power are rapidly increasing.

    In restrictive-type anorexia nervosa (AN) patients, physical activity is usually associated with food restriction, but its physiological consequences remain poorly characterized. In female mice, we evaluated the impact of voluntary physical activity with/without chronic food restriction on metabolic and endocrine parameters that might contribute to AN. In this protocol, FRW mice (i.e., food restriction with running wheel) reached a crucial point of body weight loss (especially fat mass) faster than FR mice (i.e., food restriction only). However, in contrast to FR mice, their body weight stabilized, demonstrating a protective effect of a moderate, regular physical activity. Exercise delayed meal initiation and duration. FRW mice displayed food anticipatory activity compared with FR mice, which was strongly diminished with the prolongation of the protocol. The long-term nature of the protocol enabled assessment of bone parameters similar to those observed in AN patients. Both restricted groups adapted their energy metabolism differentially in the short and long term, with less fat oxidation in FRW mice and a preferential use of glucose to compensate for the chronic energy imbalance. Finally, like restrictive AN patients, FRW mice exhibited low leptin levels, high plasma concentrations of corticosterone and ghrelin, and a disruption of the estrous cycle. In conclusion, our model suggests that physical activity has beneficial effects on the adaptation to the severe condition of food restriction despite the absence of any protective effect on lean and bone mass.

Ten percent of the world's population lives with disabilities without having access to their constitutional rights. Disability must be addressed on several levels: medical, rehabilitative, social and political. Disability is strongly linked to poverty. Stigma, discrimination and inability to pay limit access to health services and education and ill-health increases the treatment cost, creating a vicious circle that must be broken. Although the Constitution grants rights to disabled persons including access to health and education, these legal benefits are not always obtained or respected. To better understand and address the problem, the process for obtaining three of these legal benefits was studied among disabled pediatric patients with myelomeningocele in a specialized Institute in Rio de Janeiro. Results show a low achievement rate. Bureaucracy and the expenses with locomotion were main constrains worsened by lack of time and resources in families struggling with poverty. Other difficulties were lack of professional attention and confidence in the system, problems related to documents, unqualified educational system and locomotion constrains. PMID:18813598

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

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

    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. PMID:25831230

    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

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

  16. Science and scientific literacy vs science and scientific awareness through basic physics lectures: A study of wish and reality

    2012-06-01

    Scientific literacy was already discussed in the 1950s, as a prerequisite for the general citizen in a world increasingly served and infused by science and technology: the so-called knowledge or learning society. This kind of literacy has been described in detail by Victor Showalter in 1975, expanded by others, and later defined succinctly by the OECD in 2003. As a complement, science literacy is described also by the National Science Digital Library (NSDL) as a content knowledge needed in setting up practical models for handling daily matters with science and engineering. These important and worthy aims were studied, and compared with reality and existing conditions. One hypothesis put forward and argued for is, that it is more realistic, considering existing trends, to aim for scientific and science awareness for the general student, while scientific and science literacy remain important and worthy aims for the common good of the global community, and important to be strived for by teachers, lecturers and intellectuals. The Basic Physics lectures can also lend themselves usefully for the more realistic aim, due to the science-based nature of the present knowledge society.

    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).

    Background and Purpose— Therapeutic hypothermia is a promising strategy for treatment of acute stroke. Clinical translation of therapeutic hypothermia, however, has been hindered because of the lack of efficiency and adverse effects. We sought to enhance the clinical potential of therapeutic hypothermia by combining physical cooling (PC) with pharmacologically induced hypothermia after ischemic stroke. Methods— Wistar rats were subjected to 90-minute middle cerebral artery occlusion by insertion of an intraluminal filament. Mild-to-moderate hypothermia was induced 120 minutes after the onset of stroke by PC alone, a neurotensin receptor 1 (NTR1) agonist HPI-201 (formally ABS-201) alone or the combination of both. The outcomes of stroke were evaluated at 3 and 21 days after stroke. Results— PC or HPI-201 each showed hypothermic effect and neuroprotection in stroke rats. The combination of PC and HPI-201 exhibited synergistic effects in cooling process, reduced infarct formation, cell death, and blood-brain barrier damages and improved functional recovery after stroke. Importantly, coapplied HPI-201 completely inhibited PC-associated shivering and tachycardia. Conclusions— The centrally acting hypothermic drug HPI-201 greatly enhanced the efficiency and efficacy of conventional PC; this combined cooling therapy may facilitate clinical translation of hypothermic treatment for stroke.

    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. PMID:27103057

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

    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

    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.

    2016-01-01

    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. PMID:27014146

    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

    2012-01-01

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

    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.

    2001-07-01

    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.)

    2014-01-01

    The basic principles of the international economic law find expression in each of its specifications and practices. The principle of fairness and mutual benefit, as one of the basic principles of international economic law reflects the basic value orientation of the theory of international economic law and can provide a correct driec-tion for international economic activities. However, the principle of fairness and mutual benefit has been under controversy among international economic law circles, and some scholars think that the principle of equality and mutual benefit should be applied. The former emphasizes fairness while the latter emphasizes equality. In the in-ternational economic activities, the principle of fairness and mutual benefit is more applicable than the value of e-quality and mutual benefit so that the former is more suitable as a basic principle of international economic law.%国际经济法的每一项制度或具体实践都能体现其基本原则,其中公平互利原则作为国际经济法的基本原则之一主要体现了国际经济法理论的基本价值取向,并在国际经济活动中能够提供正确的方向指导。然而学界对于公平互利原则一直存在争议,部分学者认为国际经济法应该适用平等互利原则,前者强调公平,后者强调平等。在具体国际经济交往活动中,公平互利比平等互利更具有普适价值,公平互利原则作为国际经济法的基本原则更合适。

    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.

    Schmalz Dorothy L

    2006-03-01

    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.

  1. Measurement and Basic Physics Committee of the US cross-section evaluation working group. Annual report 1996

    International Nuclear Information System (INIS)

    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

  7. Physics without physical constants

    International Nuclear Information System (INIS)

    Following the general principles of both Newton's mechanics and Maxwell's electrodynamics, a new approach to basic equations of physics is presented. The new basic equations express fundamental laws of physics and are free from any physical constants. The necessary constants appear only through some kind of constitutive relations and by considering special solutions of the basic equations. The presented approach admits a new interpretation of fundamental physical constants, such as the Planck gravitational ones. 4 refs. (author)

    2015-01-01

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

  17. Directed basic research

    International Nuclear Information System (INIS)

    In its execution, and in the requirement of no other deliverables than knowledge generation, directed basic research is no different from conventional (self-directed) basic research. The selected areas are determined in a national perspective. Directed Basic Research may be in an area where the knowledge generation would benefit Indian Society in the long term, or it may be in an area where the results of the research would benefit Indian Industry or our strategic interests in the long term. India can become a global innovation leader provided we have technology foresight to make the right technology choices, provided we introduce coherent synergy (a phrase I coined a few years back in this context) in our science and technology related activities and provided we establish an effective innovation ecosystem. We must also selectively promote some technology areas through directed basic research. Sustainable economic development in the future requires strong and increased funding of basic research. While directed basic research should be encouraged, self-directed basic research should also receive substantially increased support. (author)

    2001-09-01

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

    International Nuclear Information System (INIS)

    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.

  13. Potential benefits of physical activity during pregnancy for the reduction of gestational diabetes prevalence and oxidative stress.

    Science.gov (United States)

    Cid, Marcela; González, Marcelo

    2016-03-01

    Changes in quality of nutrition, habits, and physical activity in modern societies increase susceptibility to obesity, which can deleteriously affect pregnancy outcome. In particular, a sedentary lifestyle causes dysfunction in blood flow, which impacts the cardiovascular function of pregnant women. The main molecular mechanism responsible for this effect is the synthesis and bioavailability of nitric oxide, a phenomenon regulated by the antioxidant capacity of endothelial cells. These alterations affect the vascular health of the mother and vascular performance of the placenta, the key organ responsible for the healthy development of the fetus. In addition to the increases in systemic vascular resistance in the mother, placental oxidative stress also affects the feto-placental blood flow. These changes can be integrated into the proteomics and metabolomics of newborns. PMID:26833143

    Background 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. Methods 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 (disability (objectively defined as loss of ability to walk 400 m) was compared between the 2 treatment groups using Cox regression, separately by socioeconomic group. Socioeconomic group×intervention interaction terms were tested. Results The effect of reducing the incidence of mobility disability was larger for those with postgraduate 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. Conclusions 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.

  2. Facilitating the entry into force and implementation of the amendment to the Convention on the Physical Protection of Nuclear Material: observations, challenges and benefits

    International Nuclear Information System (INIS)

    The Amendment to the Convention on the Physical Protection of Nuclear Material (CPPNM) was adopted in July 2005. The Amendment expands and deepens the effect of the CPPNM of 1980. However, more than nine years after its adoption and despite the perceived threat and recognized need to strengthen the CPPNM dating back some fifteen years ago, the Amendment is still not in force. Entry into force remains a major piece of unfinished business in international efforts to help ensure that nuclear material does not fall into the hands of terrorists or other criminals. Although to some CPPNM States Par ties, the pressing need for the Amendment to enter into force is clear and ts benefits are recognised, further consideration needs to be given to identifying why this has not happened. More particularly, what are the reasons why nearly half of the current CPPNM States Parties, including, those with and without nuclear material and nuclear facilities, have still not joined the Amendment? Also, what challenges do they face in joining and effectively implementing the instrument? The paper seeks to provide answers and identifies some benefits of the Amendment, as well as IAEA assistance available to Member States, upon request, to facilitate the entry into force and implementation of the Amendment.

    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...

    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...

  1. The Brazilian status on ADS R and D: Preliminary road map to a program on accelerator utilization on basic and applied nuclear physics, products and services and to drive an experimental neutron source sub critical facility

    International Nuclear Information System (INIS)

    Brazil, still a developing country, has an Industrial Nuclear Program, that although small has already achieved a good standard: two NPPs in operation, i.e., ANGRA I and II with 2 GW installed electric capacity are generating approximately 2% of the total installed electricity, a third unit under construction, a fuel cycle industry, INB, with the capability to provide fuel elements for the NPPs. The Brazilian Navy pursues a nuclear program for nuclear propulsion which includes all the front end of the fuel cycle, including the enrichment by ultracentrifuge that is being transferred also to the industrial sector (INB). Research and development is conducted by the various Research Institutes of the Brazilian Nuclear Energy Commission (CNEN): IPEN, CDTN, and IEN which have appropriate technical capability and facilities (research reactors and accelerators) to support the industrial nuclear program, provide products and services for the Brazilian society (e.g., radioisotopes), as well as to develop new technologies. It is fair to say, however, that the Brazilian research institutions do need some new challenges, mainly to motivate and to stimulate a new generation of young engineers and scientists to pursue careers in nuclear energy R and D. The Brazilian Nuclear Physics research, being pursued mainly by the Universities, has an outstanding standard. This is documented by the number of publications in international journals, scientific citations, the number and quality of scientists, and by its capability to form human resources (Ph.D. students). However, it is felt that this scientific potential, a few exceptions apart, still needs to transfer the benefits of the scientific knowledge to the Brazilian society. These boundary conditions call for a R and D program which identifies synergies, society needs, is in agreement with the international developments in science and technology, meets sustainability criteria, matches the Brazilian reality, provides an umbrella for

    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.

    International Nuclear Information System (INIS)

    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.

    2007-01-01

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

  1. Basic radiobiology

    International Nuclear Information System (INIS)

    Radiobiology, a branch of science concerned with the action of ionizing radiation on biological tissues and living organisms, is a combination of two disciplines: radiation physics and biology. For use in radiobiology and radiation protection the physical quantity that is useful for defining the quality of an ionizing radiation beam is the linear energy transfer (LET). In contrast to the stopping power, which focuses attention on the energy loss by an energetic charged particle moving through a medium, the LET focuses attention on the linear rate of energy absorption by the absorbing medium as the charged particle traverses the medium. When cells are exposed to ionizing radiation the standard physical effects between radiation and the atoms or molecules of the cells occur first and the possible biological damage to cell functions follows later. The biological effects of radiation result mainly from damage to the DNA, which is the most critical target within the cell; however, there are also other sites in the cell that, when damaged, may lead to cell death

    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”).

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.

    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 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).

    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. ...

    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.

      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...

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.

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.

  7. Basic physical and chemical properties of ReillexTM-HPQ anion exchange resin and its sorption behavior of halides in aqueous nitric acid solution

    International Nuclear Information System (INIS)

    The ReillexTM-HPQ anion exchange resin has a good potential toward the pretreatment of liquid nuclear wastes. In this work, a short procedure was devised to convert 99.997% of the resin from its chloride form to the nitrate form as a foundation of all quantitative measurements. It is determined that the resin can be dried to a constant mass at 60 degree C in 28 hours and the electrostatic effect during weighings can hence be eliminated. The weight ratio between resins dried at 110 degree C and 60 degree C is 0.927±0.005 (one standard deviation). The resin has an apparent pKa of 3.36±0.05. The sorption capacity from primarily the weakly basic ionogenic sites (RNH+) is 1.08±0.04 meq/g for resins dried at 60 degree C. In highly basic solutions, the resin became unstable and started to release a substantial amount of methanol. In nitric acid solutions, the selectivity sequence of halide ions versus nitrate and pertechnetate ions is: TcO4- > I- > NO3- > Br- > Cl- > F-. The HPQ resin showed no sorption of fluoride ions. Although the sorption of chloride ions is also low the data can be modeled well by an equation similar to the Freundlich isotherm at a pH range between 2.0 and 3.0. Both bromide and iodide ions showed moderate sorptions when [HNO3] = 1.00 M and the sorption data can be fitted well to an equation closely related to the Temkin isotherm. 25 refs., 6 figs., 5 tabs

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

    The Joint Institute for Nuclear Research (JINR) at Dubna has built a new 12 GeV/c accelerator with superconducting magnets (the Nuclotron) which can provide 3-12 GeV/c polarized deuteron beams, with high intensity and good polarization. Using a break-up of accelerated deuterons, it is possible to obtain quasi-monoenergetic polarized neutron and proton beams; to get full benefit to this opportunity, the experiments with polarized beams must be performed in conjunction with polarized proton or deuteron targets. The CEA proposed to use the polarized proton target (PPT), previously used at Fermilab; a collaboration has been set up in order to reconstruct the PPT as a `movable` polarized target (MPT), which could be easily transported from one beam line to another and to get this unit operating in Russia. A new magnet has to be built and transversal holding coils added. The project phases are presented and three experiments are already proposed: measurements of the difference in the transmission cross sections of polarized neutrons through the PPT when beam and target polarization are parallel or antiparallel; measurements of the spin effects in the backward elastic scattering of transversally deuterons on transversally polarized protons; {phi} meson production with polarized deuteron or proton beams and the PPT. 1 fig.

  14. Benefits to society from space exploration and use

    Science.gov (United States)

    Doyle, Stephen E.

    Many obvious benefits to society from the exploration and use of outer space have been reported. The conviction that such benefits exist is what motivates national governments to provide funding for national space programs. There is a well known litany of improvements in space applications and space science, as well as the benefits to technology development and basic research in physical sciences. These are the generally visible and often discussed benefits. There are also numerous indirect and less well known benefits that accrue to society. The stimulation of electronics miniaturization, for example, contributes to improvements in medicine, manufacturing processes, and many new forms of automation. New materials development provides advances in aeronautical, maritime and terrestrial transportation and communication systems. In the past 30 years, these developments have also: (1) stimulated improved and expanded educational and research programs: (2) created new organizations: (3) generated jobs: and (4) fostered new forms and sources of national and personal pride and prestige. Rarely is there articulation of the more metaphysical aspects of the philosophical and psychological benefits of the exploration and use of space for society. While this paper touches on many primary, secondary and tertiary physical and industrial benefits, it also deals with the more ephemeral and philosophical benefits that are infrequently explored. Although fascinating stories of courageous development programs in astronautics can be told of programs in Argentina, Brazil, Indonesia, Kenya, Mexico and other countries, there is perhaps no story as dramatic as the story of India as it undertook and pursued major space program development over the past 30 years. Examined in some detail, the story of India indicates clearly how participation in space exploration and use produces benefits to a national society as well as to the international soceity of mankind.

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

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

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

To be able to produce optimal nanosystems with tailor-made properties, it is necessary to analyze and construct such systems in advance by adequate theoretical and computational methods. Since we work in nanoscience and nanotechnology at the ultimate level, we have to apply the basic laws of physics. What methods and tools are relevant here? The book gives an answer to this question. The background of the theoretical methods and tools is critically discussed, and also the world view on which these physical laws are based. Such a debate is not only of academic interest but is of highly general concern, and this is because we constantly move in nanoscience and nanotechnology between two extreme poles, between infinite life and total destruction .

    Climate change poses many risks and challenges for the Arctic and sub-Arctic, including threats to infrastructure. The safety and stability of infrastructure in this region can be impacted by many factors including increased thawing of permafrost soils, reduced coastline protection due to declining arctic sea ice, and changes in inland flooding. The U.S. Environmental Protection Agency (EPA) is coordinating an effort to quantify physical and economic impacts of climate change on public infrastructure across the state of Alaska and estimate how global greenhouse gas (GHG) mitigation may avoid or reduce these impacts. This research builds on the Climate Change Impacts and Risk Analysis (CIRA) project developed for the contiguous U.S., which is described in an EPA report released in June 2015. We are using a multi-model analysis focused primarily on the impacts of changing permafrost, coastal erosion, and inland flooding on a range of infrastructure types, including transportation (e.g. roads, airports), buildings and harbors, energy sources and transmission, sewer and water systems, and others. This analysis considers multiple global GHG emission scenarios ranging from a business as usual future to significant global action. These scenarios drive climate projections through 2100 spanning a range of outcomes to capture variability amongst climate models. Projections are being combined with a recently developed public infrastructure database and integrated into a version of the Infrastructure Planning Support System (IPSS) we are modifying for use in the Arctic and sub-Arctic region. The IPSS tool allows for consideration of both adaptation and reactive responses to climate change. Results of this work will address a gap in our understanding of climate change impacts in Alaska, provide estimates of the physical and economic damages we may expect with and without global GHG mitigation, and produce important insights about infrastructure vulnerabilities in response to

  14. 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.

    In this study, changes from past to present in the departments of physics, chemistry, biology and mathematics, which are considered as the basic sciences in Turkey, are shown. The importance of basic science for the country emphasized and the status of our country was discussed with a critical perspective. The number of academic staff, the number of students, opened quotas according to years for these four departments at universities were calculated and analysis of the resulting changes were made. In examined graphics changes to these four departments were similar. Especially a significant change was observed in the physics department. Lack of jobs employing young people who have graduated from basic science is also an issue that must be discussed. There are also qualitative results of this study that we have discussed as quantitative. Psychological problems caused by unemployment have become a disease among young people. This study was focused on more quantitative results. We have tried to explain the causes of obtained results and propose solutions.

    The use of cyclotrons and synchrotrons to accelerate charged particles in hospital settings for the purpose of cancer therapy is increasing. Consequently, there is a growing demand from medical physicists, radiographers, physicians and oncologists for articles that explain the basic physical concepts of these technologies. There are unique advantages and disadvantages to all methods of acceleration. Several promising alternative methods of accelerating particles also have to be considered since they will become increasingly available with time; however, there are still many technical problems with these that require solving. This article serves as an introduction to this complex area of physics, and will be of benefit to those engaged in cancer therapy, or who intend to acquire such technologies in the future.

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

    Ethical considerations of animal protection and welfare require that the use of experimental animals is limited as much as possible. Animal experiments should only be performed when no alternative is available and when the benefit of the experiment outweighs the suffering of the animal. This review paper describes the basic principles for the ethical use of experimental animals. These are: "Three Rs rule" (replacement, reduction and refinement), "five fr...

    An advanced-level treatment of the basics of set theory, this text offers students a firm foundation, stopping just short of the areas employing model-theoretic methods. Geared toward upper-level undergraduate and graduate students, it consists of two parts: the first covers pure set theory, including the basic motions, order and well-foundedness, cardinal numbers, the ordinals, and the axiom of choice and some of it consequences; the second deals with applications and advanced topics such as point set topology, real spaces, Boolean algebras, and infinite combinatorics and large cardinals. An

    The topic of my bachelor's thesis is the employee motivation and benefits. The thesis is divided in two parts, a theoretical one and a practical one. The theoretical part deals with the theory of motivation and individual employee benefits. The practical part describes employee benefits in ČSOB, where I did my research by questionnaires that were filled in by employees from different departments of ČSOB. These employees answered questions about their work motivation and benefits. The resultts...

    International Nuclear Information System (INIS)

    The veterinarian must be able to diagnose several types of dental problems. History, physical examination, clinical pathology, and radiography are important in making an accurate diagnosis. Basic oral surgery includes various extraction techniques and management of their associated complications. Knowledge of dental anatomy and proper surgical technique can make an extraction curative rather than a frustrating procedure with multiple complications
