Motivating Calculus-Based Kinematics Instruction with Super Mario Bros

NASA Astrophysics Data System (ADS)

Nordine, Jeffrey C.

2011-09-01

High-quality physics instruction is contextualized, motivates students to learn, and represents the discipline as a way of investigating the world rather than as a collection of facts and equations. Inquiry-oriented pedagogy, such as problem-based instruction, holds great promise for both teaching physics content and representing the process of doing real science.2 A challenge for physics teachers is to find instructional contexts that are meaningful, accessible, and motivating for students. Today's students are spending a growing fraction of their lives interacting with virtual environments, and these environments—physically realistic or not—can provide valuable contexts for physics explorations3-5 and lead to thoughtful discussions about decisions that programmers make when designing virtual environments. In this article, I describe a problem-based approach to calculus-based kinematics instruction that contextualizes students' learning within the Super Mario Bros. video game—a game that is more than 20 years old, but still remarkably popular with today's high school and college students.

Additional security features for optically variable foils

NASA Astrophysics Data System (ADS)

Marshall, Allan C.; Russo, Frank

1998-04-01

For thousands of years, man has exploited the attraction and radiance of pure gold to adorn articles of great significance. Today, designers decorate packaging with metallic gold foils to maintain the prestige of luxury items such as perfumes, chocolates, wine and whisky, and to add visible appeal and value to wide range of products. However, today's products do not call for the hand beaten gold leaf of the Ancient Egyptians, instead a rapid production technology exists which makes use of accurately coated thin polymer films and vacuum deposited metallic layers. Stamping Foils Technology is highly versatile since several different layers may be combined into one product, each providing a different function. Not only can a foil bring visual appeal to an article, it can provide physical and chemical resistance properties and also protect an article from human forms of interference, such as counterfeiting, copying or tampering. Stamping foils have proved to be a highly effective vehicle for applying optical devices to items requiring this type of protection. Credit cards, bank notes, personal identification documents and more recently high value packaged items such as software and perfumes are protected by optically variable devices applied using stamping foil technology.

The top quark, discovered in 1995 by the CDF and D0 collaborations at the Tevatron collider at Fermilab, is the heaviest known elementary particle today. Due to its high mass and short lifetime, the top quark plays a special role in searching for physics beyond the Standard Model. In this article, recent results of searches for new physics in the top sector, performed by CDF and D0, are presented. In particular, we discuss the search for ttbar resonances, for tj resonances, the search for heavy fourth generation quarks, for dark matter produced in association with single tops, the study ofmore » anomalous couplings, the search for boosted top quarks as well as the analysis of Lorentz Invariance violation in the top quark sector.« less

History at the intersection of disability and public health: the case of John Galsworthy and disabled soldiers of the First World War.

PubMed

Reznick, Jeffrey S

2011-01-01

The author presented an earlier version of this historical article to the Disability Section of the American Public Health Association (November 2009). It is part of his ongoing research in the social and cultural history of medicine as the field intersects with the history of disability, veterans, and public health, as well as current issues that touch all of these areas. This article introduces readers to perspectives on disability held by the British novelist John Galsworthy (1867-1933), which he developed primarily through his philanthropic support for and his compositions about rehabilitation programs for British and American soldiers disabled in the First World War (1914-1918). Readers will learn that Galsworthy's perspectives are as much about his identity as an individual with disabilities as they are about men disabled in the "war to end all wars." The rediscovery of Galsworthy's experiences and words more than 90 years after the end of World War I reveals how history is present today at the intersection of disability and public health. Indeed, the story of Galsworthy ultimately seeking to forget his own experiences during the "Great War," as well as the very physical and psychological disability caused by that conflict, can inspire public health professionals and disability rights advocates today to remember-indeed, to advocate for-men and women who served in battle and have returned home to realize renewed health and social participation despite permanent physical and psychological wounds. Readers will note that language used throughout this article to describe disability is period-specific and therefore not keeping with current conventions. Published by Elsevier Inc.

Strategic planning for future learning environments: an exploration of interpersonal, interprofessional and political factors.

PubMed

Schmidt, Cathrine

2013-09-01

This article, written from the stance of a public planner and a policy maker, explores the challenges and potential in creating future learning environments through the concept of a new learning landscape. It is based on the belief that physical planning can support the strategic goals of universities. In Denmark, a political focus on education as a mean to improve national capacity for innovation and growth are redefining the universities role in society. This is in turn changing the circumstances for the physical planning. Drawing on examples of physical initiatives in three different scales--city, building and room scale, the paper highlights how space and place matters on an interpersonal, an interprofessional and a political level. The article suggests that a wider understanding of how new learning landscapes are created--both as a material reality and a political discourse--can help frame an emerging community of practice. This involves university leaders, faculty and students, architects, designers and urban planners, citizens and policy makers with the common goal of creating future learning environments today.

A recent trend in computer science and related fields is general purpose computing on graphics processing units (GPUs), which can yield impressive performance. With multiple cores connected by high memory bandwidth, today's GPUs offer resources for non-graphics parallel processing. This article provides a brief introduction into the field of GPU computing and includes examples. In particular computationally expensive analyses employed in financial market context are coded on a graphics card architecture which leads to a significant reduction of computing time. In order to demonstrate the wide range of possible applications, a standard model in statistical physics - the Ising model - is ported to a graphics card architecture as well, resulting in large speedup values.

Radio detection of extensive air showers initiated in the Earth's atmosphere has made tremendous progress in the last decade. Today, radio detection is routinely used in several cosmic-ray observatories. The physics of the radio emission in air showers is well-understood, and analysis techniques have been developed to determine the arrival direction, the energy and an estimate for the mass of the primary particle from the radio measurements. The achieved resolutions are competitive with those of more traditional techniques. In this article, I shortly review the most important achievements and discuss the potential for future applications.

Policy approach to nutrition and physical activity education in health care professional training1234

2014-01-01

Nutrition and physical activity are key risk factors for a host of today's most prevalent and costly chronic conditions, such as obesity and diabetes; yet, health care providers are not adequately trained to educate patients on the components of a healthy lifestyle. The purpose of this article is to underscore the need for improved nutrition and physical activity training among health care professionals and to explore opportunities for how policy can help support a shift in training. We first identify key barriers to sufficient training in nutrition and physical activity. Then, we provide an overview of how recent changes in the government and institutional policy environment are supporting a shift toward prevention in our health care system and creating an even greater need for improved training of health care professionals in nutrition and physical activity. Last, we outline recommendations for additional policy changes that could drive enhanced training for health care professionals and recommend future directions in research. PMID:24646822

Tensegrity II. How structural networks influence cellular information processing networks

NASA Technical Reports Server (NTRS)

Ingber, Donald E.

2003-01-01

The major challenge in biology today is biocomplexity: the need to explain how cell and tissue behaviors emerge from collective interactions within complex molecular networks. Part I of this two-part article, described a mechanical model of cell structure based on tensegrity architecture that explains how the mechanical behavior of the cell emerges from physical interactions among the different molecular filament systems that form the cytoskeleton. Recent work shows that the cytoskeleton also orients much of the cell's metabolic and signal transduction machinery and that mechanical distortion of cells and the cytoskeleton through cell surface integrin receptors can profoundly affect cell behavior. In particular, gradual variations in this single physical control parameter (cell shape distortion) can switch cells between distinct gene programs (e.g. growth, differentiation and apoptosis), and this process can be viewed as a biological phase transition. Part II of this article covers how combined use of tensegrity and solid-state mechanochemistry by cells may mediate mechanotransduction and facilitate integration of chemical and physical signals that are responsible for control of cell behavior. In addition, it examines how cell structural networks affect gene and protein signaling networks to produce characteristic phenotypes and cell fate transitions during tissue development.

Unification of force and substance.

PubMed

Wilczek, Frank

2016-08-28

Maxwell's mature presentation of his equations emphasized the unity of electromagnetism and mechanics, subsuming both as 'dynamical systems'. That intuition of unity has proved both fruitful, as a source of pregnant concepts, and broadly inspiring. A deep aspect of Maxwell's work is its use of redundant potentials, and the associated requirement of gauge symmetry. Those concepts have become central to our present understanding of fundamental physics, but they can appear to be rather formal and esoteric. Here I discuss two things: the physical significance of gauge invariance, in broad terms; and some tantalizing prospects for further unification, building on that concept, that are visible on the horizon today. If those prospects are realized, Maxwell's vision of the unity of field and substance will be brought to a new level.This article is part of the themed issue 'Unifying physics and technology in light of Maxwell's equations'. © 2016 The Author(s).

The aim of this article is to determine the origin of interest in rhinoplasty in ancient India, as well as to discuss the ethical and aesthetic implications of the nose in human history. Literature review. Articles on history of medical ethics and rhinoplastic surgery were reviewed. Sushruta is considered "the father of plastic surgery," and ancient India a cradle of rhinoplastic method called "the Indian method." Origin of interest in and need for rhinoplasty is deeply rooted in ancient Indian society due to the practice of nose mutilations as a form of public punishment for immoral conduct. The nose, once symbol of morality expressed through physical integrity, today becomes an important factor of human beauty. Rhinoplastic surgery is, both then and now, deeply pervaded with both ethics and aesthetics.

Strangeness from SPS to FAIR: Searching for the onset of deconfinement

NASA Astrophysics Data System (ADS)

Friese, Volker

2017-12-01

Since the early days of heavy-ion physics, strangeness has been considered a sensitive probe of the state of matter created in nuclear collisions. This assessment still holds today, where we are witnessing renewed interest in collisions at moderate energies, manifested in the running or projected experimental programmes at RHIC, SPS, FAIR, and NICA. In this article, we will review the current understanding of strangeness production at lower energies and discuss how far future measurement of strange particles can contribute to understanding the properties of dense QCD matter and to the search for the onset of deconfinement.

Today smartphones and tablets do not merely pervade our daily life, but also play a major role in STEM education in general, and in experimental investigations in particular. Enabling teachers and students to make use of these new techniques in physics lessons requires supplying capable and affordable applications. Our article presents the improvement of a low-cost technique turning smartphones into powerful magnifying glasses or microscopes. Adding only a 3D-printed clip attached to the smartphone's camera and inserting a small glass bead in this clip enables smartphones to take pictures with up to 780x magnification (see Fig. 1). In addition, the construction of the smartphone attachments helps to explain and examine the differences between magnifying glasses and microscopes, and shows that the widespread term "smartphone microscope" for this technique is inaccurate from a physics educational perspective.

Friendship networks and physical activity and sedentary behavior among youth: a systematized review.

PubMed

Sawka, Keri Jo; McCormack, Gavin R; Nettel-Aguirre, Alberto; Hawe, Penelope; Doyle-Baker, Patricia K

2013-12-01

Low levels of physical activity and increased participation in sedentary leisure-time activities are two important obesity-risk behaviors that impact the health of today's youth. Friend's health behaviors have been shown to influence individual health behaviors; however, current evidence on the specific role of friendship networks in relation to levels of physical activity and sedentary behavior is limited. The purpose of this review was to summarize evidence on friendship networks and both physical activity and sedentary behavior among children and adolescents. After a search of seven scientific databases and reference scans, a total of thirteen articles were eligible for inclusion. All assessed the association between friendship networks and physical activity, while three also assessed sedentary behavior. Overall, higher levels of physical activity among friends are associated with higher levels of physical activity of the individual. Longitudinal studies reveal that an individual's level of physical activity changes to reflect his/her friends' higher level of physical activity. Boys tend to be influenced by their friendship network to a greater extent than girls. There is mixed evidence surrounding a friend's sedentary behavior and individual sedentary behavior. Friends' physical activity level appears to have a significant influence on individual's physical activity level. Evidence surrounding sedentary behavior is limited and mixed. Results from this review could inform effective public health interventions that harness the influence of friends to increase physical activity levels among children and adolescents.

Diversity, culture and the glass ceiling.

Wilson, Eleanor

2014-01-01

A reference to the term, the glass ceiling, has come to embody more than gender equality among women and men. Today the term embraces the quest of all minorities and their journey towards equality in the workplace. The purpose of this article is to bring attention to the subject of diversity, culture, and the glass ceiling. The article will discuss the history of the glass ceiling and how its broadened meaning is relevant in today's workplace. It will also provide statistics showing how diversity and culture are lacking among the top echelon of today's executives, the barriers faced by minorities as they journey towards executive leadership, and how to overcome these barriers to truly shatter the glass ceiling.

A historical perspective of synthetic ceramic and traditional feldspathic porcelain.

Ceramics were invented by the Chinese during the T'ang Dynasty, where they quickly became a precious commodity. By the early 18th Century, ceramics found its way into dentistry due to its high strength, biocompatibility, and malleability. Today, ceramic materials are a staple in dentistry, available in both naturally based and partially synthetic formulas. Most recently they have become available as quartz-glass synthetic materials manufactured under controlled conditions to eliminate the inconsistencies and impurities inherent in the naturally based counterpart. This article details the discovery of porcelain and its role as a precious substance throughout the world and time, from its initial use as ornamental earthenware to its practical application in modern dentistry. Upon reading this article, the reader should: Understand the historical significance of porcelain. Recognize the fundamental constituents and physical properties of both natural feldspathic porcelains and fully synthetic ceramics used in dentistry.

Physics and instrumentation for imaging in-vivo drug distribution.

Several imaging methods are currently available to measure drugs noninvasively. Of these, two techniques are today central to such measurements: nuclear imaging and magnetic resonance imaging/spectroscopy (MRI and MRS). While other methods, such as optical techniques, are rapidly gaining in interest, they have not yet attained the degree of development that makes them effective in measuring drugs in living systems, except in a small number of examples. The following introduction provides some basic elements of the potential and the limitations of both nuclear imaging and MRI/MRS techniques, methods that will be used in the studies described in the articles in this issue. However, and for those desiring to gain a better understanding of both methods, the reader is advised to consult much more extensive reviews and books describing such methods. A suggested list of books and articles on Nuclear Imaging and MRI/MRS is given.

Regular physical activity can have a positive effect on health at any age. Today's lifestyles, however, can often be characterised as sedentary. Therefore, the promotion of physical activity and sports has become an integral part of public health measures. The representative data of adults aged 18 to 79 years in Germany obtained from the "German Health Interview and Examination Survey for Adults" (DEGS1) provide an overview of self-estimated current physical activity behaviour. The results show that one third of the adult population claims to pay close attention to reaching a sufficient level of physical activity and one fourth participates in sports for at least 2 h/week on a regular basis. Thus, the percentage of adults regularly engaged in sports has increased compared to the previous "German National Health Interview and Examination Survey 1998". Still, four out of five adults do not achieve at least 2.5 h/week of moderate-intensity physical activity as recommended by the World Health Organisation. Consequently, future individual-level and population-level interventions should focus on target group-specific measures while continuing to promote regular physical activity in all segments of the population.

EDITORIAL: Non-thermal plasma-assisted fuel conversion for green chemistry Non-thermal plasma-assisted fuel conversion for green chemistry

Nozaki, Tomohiro; Gutsol, Alexander

2011-07-01

This special issue is based on the symposium on Non-thermal Plasma Assisted Fuel Conversion for Green Chemistry, a part of the 240th ACS National Meeting & Exposition held in Boston, MA, USA, 22-26 August 2010. Historically, the Division of Fuel Chemistry of the American Chemical Society (ACS) has featured three plasma-related symposia since 2000, and has launched special issues in Catalysis Today on three occasions: 'Catalyst Preparation using Plasma Technologies', Fall Meeting, Washington DC, USA, 2000. Special issue in Catalysis Today 72 (3-4) with 12 peer-reviewed articles. 'Plasma Technology and Catalysis', Spring Meeting, New Orleans, LA, USA, 2003. Special issue in Catalysis Today 89 (1-2) with more than 30 peer-reviewed articles. 'Utilization of Greenhouse Gases II' (partly focused on plasma-related technologies), Spring Meeting, Anaheim, CA, USA, 2004. Special issue in Catalysis Today 98 (4) with 25 peer-reviewed articles. This time, selected presentations are published in this Journal of Physics D: Applied Physics special issue. An industrial material and energy conversion technology platform is established on thermochemical processes including various catalytic reactions. Existing industry-scale technology is already well established; nevertheless, further improvement in energy efficiency and material saving has been continuously demanded. Drastic reduction of CO2 emission is also drawing keen attention with increasing recognition of energy and environmental issues. Green chemistry is a rapidly growing research field, and frequently highlights renewable bioenergy, bioprocesses, solar photocatalysis of water splitting, and regeneration of CO2 into useful chemicals. We would also like to emphasize 'plasma catalysis' of hydrocarbon resources as an important part of the innovative next-generation green technologies. The peculiarity of non-thermal plasma is that it can generate reactive species almost independently of reaction temperature. Plasma-generated reactive species are used to initiate chemical reactions at unexpectedly lower temperatures than conventional thermochemical reactions, leading to non-equilibrium product distribution or creating unconventional reaction pathways. When non-thermal plasma is combined with catalysts, a synergistic effect is frequently observed. Such unique properties of non-thermal plasma are expected to contribute excellent control over process parameters that meet the need for energy saving, environment protection, and material preservation. This special issue consists of eleven peer-reviewed papers including two invited publications. Professors Alexander Fridman and Alexander Rabinovich from Drexel University, and Dr Gutsol from the Chevron Energy Technology Company present a critical review of various industry-oriented practical plasma fuel conversion processes. Professor Richard Mallinson from University of Oklahoma describes his recent project on E85 (85%-ethanol/15%-gasoline) upgrading using non-thermal plasma and catalyst hybrid reactor, and highlights the synergistic effect on fuel conversion processes. Other papers focus on plasma/catalyst hybrid reactions for methane dry (CO2) reforming, plasma synthesis of carbon suboxide polymer from CO, the gas-to-liquid (GTL) process using a non-thermal plasma-combined micro-chemical reactor, and molecular beam characterization of plasma-generated reactive species. Much research regarding plasma catalysis is ongoing worldwide, but there is plenty of room for further development of plasma fuel processing, which could eventually provide a viable and flexible solution in future energy and material use. Finally, we would like to thank all symposium participants for their active discussion. We appreciate the sponsorship of the Division of Fuel Chemistry of the American Chemical Society. We express special thanks to the program chair of the Fuel Chemistry Division, Professor Chang-jun Liu at Tianjin University, for his dedication to the success of the symposium. We particularly express our appreciation to the Editorial Board of Journal of Physics D: Applied Physics for publication of the special issue.

Two points in our recent article on Edward Teller's scientific life (Physics Today, August 2004, page 45) require correction. In our description of Teller's students, we incorrectly stated that Arthur Kantrowitz's thesis was on the generation of hypersonic molecular beams. Actually, his thesis was on heat capacity lags in gas dynamics. Kantrowitz's invention of high intensity sources for molecular beams came later in his career. Maurice Goldhaber has emphasized that the situation with respect to possible nuclear resonances in ({gamma},n) or ({gamma},fission) reactions was quite unclear at the time of George C. Baldwin and G. Stanley Klaiber's papers on thesemore » reactions. This was because the rapid rise of their yield to a prominent peak with increasing energy, followed by a slower fall off was then thought to have been due to the competition between the rapidly rising density of nuclear states and the eventual domination of other reaction channels at higher energies. Goldhaber realized, however, that there could be an analogy between a possible collective nuclear resonance and the restrahl resonance (essentially the transverse optical phonon mode) in polar crystals. Goldhaber sought out Teller because of his paper with Russell Lyddane and Robert Sachs, relating the restrahl frequency to the asymptotic behavior of the crystal's dielectric function. Goldhaber and Teller, in their paper together, went on to predict universal, giant photo-nuclear resonances.« less

Schools and obesity prevention: creating school environments and policies to promote healthy eating and physical activity.

Story, Mary; Nanney, Marilyn S; Schwartz, Marlene B

2009-03-01

Research consistently shows that the majority of American children do not consume diets that meet the recommendations of the Dietary Guidelines for Americans, nor do they achieve adequate levels of daily physical activity. As a result, more children are overweight today than at any other time in U.S. history. Schools offer many opportunities to develop strategies to prevent obesity by creating environments in which children eat healthfully and engage regularly in physical activity. This article discusses the role of schools in obesity prevention efforts. Current issues in schools' food and physical activity environments are examined, as well as federal, state, and local policies related to food and physical activity standards in schools. The article is organized around four key areas: (1) school food environments and policies, (2) school physical activity environments and policies, (3) school body mass index measurements, and (4) school wellness policies. Recommendations for accelerating change also are addressed. The article found that (1) competitive foods (foods sold outside of federally reimbursed school meals) are widely available in schools, especially secondary schools. Studies have related the availability of snacks and drinks sold in schools to students' high intake of total calories, soft drinks, total fat and saturated fat, and lower intake of fruits and vegetables; (2) physical activity can be added to the school curriculum without academic consequences and also can offer physical, emotional, and social benefits. Policy leadership has come predominantly from the districts, then the states, and, to a much lesser extent, the federal government; (3) few studies have examined the effectiveness or impact of school-based BMI measurement programs; and (4) early comparative analyses of local school wellness policies suggest that the strongest policies are found in larger school districts and districts with a greater number of students eligible for a free or reduced-price lunch. Studies show that schools have been making some progress in improving the school food and physical activity environments but that much more work is needed. Stronger policies are needed to provide healthier meals to students at schools; limit their access to low-nutrient, energy-dense foods during the school day; and increase the frequency, intensity, and duration of physical activity at school.

Friedrich Robert Helmert died in Potsdam in 1917 at the age of 74 after serving for over 30 years as director of the Royal Prussian Geodetic Institute and of the Central Bureau of the Internationale Erdmessung, the forerunner of today's International Association of Geodesy. He dedicated his life and his scientific career to the field of geodesy. His teachings on theoretical and physical geodesy were incorporated into university curricula around the world and hence into international endeavours to measure planet Earth. The purpose of this article is to illustrate the impact he has had on the development of modern geodesy and on the related sciences.

Book Review

NASA Astrophysics Data System (ADS)

Rickles, Dean

Although ostensibly a festschrift for Gabriele Veneziano, this book also marks an important step in the historical study of string theory, featuring several excellent chapters on the earliest period of string theory, as it emerged from the study of strong interaction physics and dual resonance models. Veneziano is often crowned 'the father of string theory' since it was he who discovered the amplitude that led to the dual resonance models that then led to string theory in something like the form we know it today (though not immediately into a quantum theory of gravity). However, as the historical articles in this book make plain, Veneziano was but a small (albeit vital) component in the creation of string theory.

Pectus carinatum is a chest wall deformity, sometimes associated with physical signs and symptoms, but always associated to significant psychological distress. Surgical correction used to be the only solution, and was therefore only indicated for the most severe cases. Non-surgical approaches have been developed and improved during the last 15-20 years. A paradigm shift occured when the medical community realized that, despite the wall deformity, the chest wall was not completely rigid, but flexible and capable of remodeling. Several bracing devices and protocols are available as of today. This article will focus specifically in the FMF ® Dynamic Compressor System (DCS), which was developed in Argentina in 2001 and is currently used worldwide.

Historical Notes on the Expanding Universe

Way, Michael J.; Belenkyi, Ari; Nussbaumer, Harry; Peacock, John

2014-01-01

The article Measuring the Hubble constant by Mario Livio and Adam Riess (Physics Today, October 2013, page 41) reviewed studies of the expanding universe from the 1920s to the present. Although the history of the subject underwent considerable compression to fit the length of a magazine article, we think it may leave a misleading impression of some of the key steps to our current understanding. We therefore offer the following clarifications. Most significantly, papers by Arthur Eddington and by Willem de Sitter in 1930, who successfully promoted Georges Lematres 1927 article for the Scientific Society of Brussels, effected a paradigm shift in interpretation of extragalactic redshifts in 1930. Before then, the astronomical community was generally unaware of the existence of nonstatic cosmological solutions and did not broadly appreciate that redshifts could be thought of locally as Doppler shifts in an expanding matter distribution. Certainly, in 1929 Edwin Hubble referred only to the de Sitter solution of 1917. At the time, the relation between distance and redshift predicted in that model was generally seen purely as a manifestation of static spacetime curvature.

iRadioactivity — Possibilities and Limitations for Using Smartphones and Tablet PCs as Radioactive Counters

A study conducted in 2013 showed that about 70-80% of teens and young adults in the United States own a smartphone.1 Furthermore the number of tablet PC users in the United States will increase up to more than 80% by 2015.2 As a result, these devices have increasingly become everyday tools, particularly for the younger generation. In recent years, various articles have been published about the use of smartphones and tablet PCs as experimental tools especially in the physics classroom. This is possible because today's smartphones and tablet PCs are equipped with many sensors, which can be used to perform quantitative measurements of sound, acceleration, magnetic flux density, air pressure, light intensity, humidity, angular velocity, temperature, or position on Earth (GPS). While previous articles mainly present experiments on mechanics or acoustics, in which the acceleration sensor or the microphone is used (for a synopsis of different examples, see Ref. 3; for recent papers, see Refs.), in this article we focus on experiments for studying radioactivity using the camera sensor.

Today, it's not easy to find a telecommunications publication that doesn't have a feature article on fiber to the home. Not only do these articles appear in telecommunications publications but in newspapers like in the Wall Street Journal and USA Today. What concerns me about these articles is the immediate emphasis on CATV and video on demand services. Fiber is indeed a broadband transmission medium. However, from BellSouths point of view, the video services are not necessary to the economic equation for placing fiber to the subscriber. Our objective is to place fiber in the network for POTS like services first and upgrade the electronics based on customer demand.

Exploring the physics of sand drawings: The role of craters, furrows and piles.

PubMed

González-Gutiérrez, Jorge; Ruiz-Suárez, J C

2017-04-01

Few years ago an article addressing the physics behind aaabstract paintings was published by Herczyński et al. (Phys. Today 64, 31 (2011) issue No. 6). The authors aimed to understand how artists like Jackson Pollock manipulated paints to create pieces of art where the theory of fluid dynamics had a clear and perceivable role. Scaling laws were found to explain the plasticity observed in the artists's traces that we admire in worldwide museums. Because sand drawings are not only wonderful artistic expressions but also intangible cultural heritages of humanity, we wonder if they could be analyzed in a similar fashion. Our goal is to explore the physics behind the formation of such drawings. In order to do so, we carry out experimental studies on the formation of sand cavities, furrows and piles, which individually or interconnected, give rise to artistic patterns. Moreover, in order to manipulate such three observables, some control parameters are needed. Altogether, they conform into simple exponential and power laws that collapse when a scaling is performed.

Corvids (Corvidae) play a major role in ornithological research. Because of their worldwide distribution, diversity and adaptiveness, they have been studied extensively. The aim of the Corvids Literature Database (CLD, http://www.corvids.de/cld) is to record all publications (citation format) on all extant and extinct Crows, Ravens, Jays and Magpies worldwide and tag them with specific keywords making them available for researchers worldwide. The self-maintained project started in 2006 and today comprises 8000 articles, spanning almost 500 years. The CLD covers publications from 164 countries, written in 36 languages and published by 8026 authors in 1503 journals (plus books, theses and other publications). Forty-nine percent of all records are available online as full-text documents or deposited in the physical CLD archive. The CLD contains 442 original corvid descriptions. Here, we present a metadata assessment of articles recorded in the CLD including a gap analysis and prospects for future research. Database URL: http://www.corvids.de/cld PMID:26868053

"Permission to Speak": A Postcolonial View on Racialized Bodies and PE in the Current Context of Globalization.

PubMed

Azzarito, Laura

2016-06-01

The current neoliberal context of schools presents difficult challenges in addressing persistent issues of social inequalities. In this article, first, I argue that because of today's market-driven education, the rise of fitness testing in school physical education (PE) can be seriously detrimental to young people in general and to ethnic-minority young people's embodied identity in particular. Second, I explain how the racialization process circulated by the body-at-risk discourse, sustained by the media, and reproduced by high-stakes testing in PE forces ethnic-minority young people to construct their identities through White eyes, which alienates them from a consciousness of their own identity. Third, I explore the possible uses and pitfalls of Spivak's theoretical notion of "strategic essentialism" to put forward strategies to build a positive image of the "other" while attempting to avoid the erasure of difference. Fourth, I conclude the article by suggesting how Spivak's notion of strategic essentialism can be useful in rethinking current PE fitness practices.

Castenfors, K; Svedin, L

2001-12-14

The authors examine current trends in urban risks and resilience in relation to hazardous material transports in general, and crisis communication and the Stockholm liquefied petroleum gas (LPG) near miss in 1998 in particular. The article discusses how current dynamics affecting urban areas, such as the decay in terms of increased condensation and limited expansion alternatives combined with industry site contamination and transports of hazardous materials on old worn-out physical infrastructure, work together to produce high-risk factors and increase urban vulnerability in large parts of the world today. Crisis communication takes a particularly pronounced role in the article as challenges in communication and confidence maintenance under conditions of information uncertainty and limited information control are explored. The LPG near miss case illustrates a Swedish case of urban risk and the tight coupling to hazardous material transports. The case also serves as a current example of Swedish resilience and lack of preparedness in urban crises, with particular observations and lessons learned in regards to crisis communication.

"Mended or ended?" Football injuries and the British and American medical press, 1870-1910.

PubMed

Park, R J

2001-01-01

'Playing Hurt/Playing Tough', a dominant ideology in today's football (soccer, rugby, American 'gridiron'), is by no means new. Many books, monographs, and articles have examined the historical development of these games, but the attention given to them in the medical press during the late 1800s/early 1900s has been overlooked. The Lancet, Journal of the American Medical Association, and other turn-of-the-century medical publications regularly included accounts and descriptions of injuries and deaths. More telling were the many editorials in which physicians in both Britain and the United States expressed enthusiasm while also lamenting the games' physical and morale effects upon players, asking whether 'football' should be mended or ended.

Non-surgical treatment of pectus carinatum with the FMF® Dynamic Compressor System

PubMed Central

Martinez-Ferro, Marcelo; Bellia Munzon, Gaston; Fraire, Carlos; Abdenur, Constanza; Chinni, Emilio; Strappa, Bruno

2016-01-01

Pectus carinatum is a chest wall deformity, sometimes associated with physical signs and symptoms, but always associated to significant psychological distress. Surgical correction used to be the only solution, and was therefore only indicated for the most severe cases. Non-surgical approaches have been developed and improved during the last 15–20 years. A paradigm shift occured when the medical community realized that, despite the wall deformity, the chest wall was not completely rigid, but flexible and capable of remodeling. Several bracing devices and protocols are available as of today. This article will focus specifically in the FMF® Dynamic Compressor System (DCS), which was developed in Argentina in 2001 and is currently used worldwide. PMID:29078485

Explaining Today's Physics Through History and Biography

NASA Astrophysics Data System (ADS)

Lindley, David

2014-03-01

Quantum computers, string theory, holographic universes - to the general audience, today's physics can be as mystifying as it is fascinating. But modern ideas evolved from an earlier phase of physics - Newtonian mechanics, simple cause and effect - that is in principle easier for the non-expert to grasp. I have found that writing about physics from a historical and biographical perspective is an effective way to convey modern thinking by explaining where it comes from - it is a way of carrying the reader from concepts that make intuitive sense to ideas that seem, on first encounter, utterly bizarre. Smuggling explanations into stories satisfies the reader's desire for narrative - bearing in mind that narrative can include the evolution of ideas as well as tales about intriguing and original people.

Kohale, Ritesh L.

The objective of present work is to put forward the Santilli’s experimental, physical and mathematical conception of IsoRedShift (IRS), IsoBlueShift (IBS) and NoIsoShift (NIS). Santilli has carried out a step-by step isotopic lifting of the physical laws of special relativity resulting in a new theory today specifically known Santilli isorelativity. In his 1991 hypothesis Santilli established the requirement to realize the light as electromagnetic waves propagating within a universal substratum. Furthermore Santilli has carried out a step-by step isotopic lifting of the physical laws of special relativity resulting in a new theory today specifically known Santilli isorelativity.

The Quality of Life of Mustard Gas Victims: A Systematic Review

PubMed Central

Satkin, Mojtaba; Ghanei, Mostafa; Allahverdi, Sahar; Elikaei, Mahdi

2017-01-01

Background: Today, a host of veterans who were exposed to mustard gas suffer from substantially poor quality of life (QoL). However, factors that influence these patients’ QoL have not been yet scrutinized. QoL is deemed as a crucial construct that demands careful attention during evaluation as well as intervention. The present study aimed to delve into the physical, mental, and social factors that affect the QoL of mustard gas victims. Materials and Methods: All the physical, mental, and social parameters that influence the QoL of mustard gas victims were scrutinized through a systematic review. We searched for Persian and English scientific databases, i.e., PubMed, Scopus, and Google Scholar, and national databanks, namely SID, IranMedex, and Magiran to identify studies related to chemical victims conducted up to the end of 2015. Next, the quality of 21 articles and studies were assessed using the checklist of the National Institute of Health (NIH), and subsequently, 13 articles were selected for the stages of data extraction and analysis. Results: Findings revealed that, among the physical factors, coexistence of several medical conditions caused by chemical injury and the severity of the chemical injury had the greatest impact on the QoL of chemically injured veterans. Besides, suffering from psychological and neurological disorders, along with educational level and employment status, were the most influential psychosocial parameters that influenced veterans’ QoL. Conclusion: The review conducted herein identified the physical and psychosocial factors affecting the QoL of mustard gas victims. In fact, it is the first to present a large collection of descriptive information on QoL contributors in a systematic and orderly fashion. PMID:29308076

Thorium and Molten Salt Reactors: Essential Questions for Classroom Discussions

NASA Astrophysics Data System (ADS)

DiLisi, Gregory A.; Hirsch, Allison; Murray, Meredith; Rarick, Richard

2018-04-01

A little-known type of nuclear reactor called the "molten salt reactor" (MSR), in which nuclear fuel is dissolved in a liquid carrier salt, was proposed in the 1940s and developed at the Oak Ridge National Laboratory in the 1960s. Recently, the MSR has generated renewed interest as a remedy for the drawbacks associated with conventional uranium-fueled light-water reactors (LWRs) in use today. Particular attention has been given to the "thorium molten salt reactor" (TMSR), an MSR engineered specifically to use thorium as its fuel. The purpose of this article is to encourage the TPT community to incorporate discussions of MSRs and the thorium fuel cycle into courses such as "Physics and Society" or "Frontiers of Physics." With this in mind, we piloted a pedagogical approach with 27 teachers in which we described the underlying physics of the TMSR and posed five essential questions for classroom discussions. We assumed teachers had some preexisting knowledge of nuclear reactions, but such prior knowledge was not necessary for inclusion in the classroom discussions. Overall, our material was perceived as a real-world example of physics, fit into a standards-based curriculum, and filled a need in the teaching community for providing unbiased references of alternative energy technologies.

Variation in Generational Perceptions of Child Health and Well-being.

Freed, Gary L; Davis, Matthew M; Singer, Dianne C; Gebremariam, Acham; Schultz, Sara L; Matos-Moreno, Amilcar; Wietecha, Mark

To assess adults' perceptions regarding the health and well-being of children today relative to their own health and well-being as youth and the potential for intergenerational differences in those perceptions. A cross-sectional, Internet-based survey of a nationally representative household sample was conducted using GfK Custom Research's Web-enabled KnowledgePanel, a probability-based panel representative of the US population. We assessed perceptions of children's health and well-being today compared to when respondents were growing up, including physical and mental health; and children's education, exercise, diet, health care, safety of communities, and emotional support from families, groups, and organizations. Overall, 1330 (65%) of 2047 adult respondents completed the survey. Only 26% of respondents believed that the current physical health of children, and 14% that the current mental health of children, is better today than when they were growing up. There was a significant trend among generations, with a greater proportion of older generations perceiving the physical health of children to be better today. Only 15% of respondents reported the chances for a child to grow up with good mental health in the future are "better" now than when they were growing up. Adults across all generations in the United States today view children's health as unlikely to meet the goals of the American Dream of continuous improvement. Although demographic changes require continued focus on our aging population, we must equally recognize the importance of advancing a healthy future for our nation's children, who will assume the mantle of our future.

Meeting the global demand of sports safety: the intersection of science and policy in sports safety.

PubMed

Timpka, Toomas; Finch, Caroline F; Goulet, Claude; Noakes, Tim; Yammine, Kaissar

2008-01-01

Sports and physical activity are transforming, and being transformed by, the societies in which they are practised. From the perspectives of both competitive and non-competitive sports, the complexity of their integration into today's society has led to neither sports federations nor governments being able to manage the safety problem alone. In other words, these agencies, whilst promoting sport and physical activity, deliver policy and practices in an uncoordinated way that largely ignores the need for a concurrent overall policy for sports safety. This article reviews and analyses the possibility of developing an overall sports safety policy from a global viewpoint. Firstly, we describe the role of sports in today's societies and the context within which much sport is delivered. We then discuss global issues related to injury prevention and safety in sports, with practical relevance to this important sector, including an analysis of critical policy issues necessary for the future development of the area and significant safety gains for all. We argue that there is a need to establish the sports injury problem as a critical component of general global health policy agendas, and to introduce sports safety as a mandatory component of all sustainable sports organizations. We conclude that the establishment of an explicit intersection between science and policy making is necessary for the future development of sports and the necessary safety gains required for all participants around the world. The Safe Sports International safety promotion programme is outlined as an example of an international organization active within this arena.

Compensation for psychiatric injury: evolution of a law of nervous shock.

PubMed

Griffith, Richard

2006-09-01

District nurses will be well aware that if a person receives an injury because of someone else's negligence they are entitled to compensation for the harm that has been caused. However, where the injury is in the form of psychiatric harm the law has traditionally imposed rules that set out the conditions to be met before a successful claim for damages can be made. Even in today's enlightened society the law still does not always treat a psychiatric injury in the same way as a physical injury. In this article Richard Griffith outlines the development of the law in relation to psychiatric injury--historically called "nervous shock"--and considers the current approach to claims for damages where a person suffers psychiatric harm because of another's negligent act.

[Teaching skills of functional assessment to medical students: why not playing games?].

PubMed

Huber, Philippe; Saber, Abdelmalek; Schnellmann, Yves; Gold, Gabriel

2012-11-07

Today, physicians take care of an aging population suffering from multiple chronic diseases and disabilities. Therefore, a good knowledge of functional assessment is required, and this topic should be addressed in the undergraduate medical curriculum. This article reports our experience with a seminar on functional assessment using an "aging game" as a pedagogic vector. This seminar is organized by geriatricians, occupational therapists and physical therapists. Medical students are exposed to situations where they experiment disabilities and try to elaborate compensatory strategies. Then, they reflect on a complex discharge project by analyzing a written clinical case. Finally, they are introduced to the use of validated functional assessment instruments. Evaluation indicated that this pedagogic approach is highly valued by students and fosters the acquisition of knowledge in functional assessment.

Conformal Infinity.

Frauendiener, Jörg

2000-01-01

The notion of conformal infinity has a long history within the research in Einstein's theory of gravity. Today, "conformal infinity" is related with almost all other branches of research in general relativity, from quantisation procedures to abstract mathematical issues to numerical applications. This review article attempts to show how this concept gradually and inevitably evolved out of physical issues, namely the need to understand gravitational radiation and isolated systems within the theory of gravitation and how it lends itself very naturally to solve radiation problems in numerical relativity. The fundamental concept of null-infinity is introduced. Friedrich's regular conformal field equations are presented and various initial value problems for them are discussed. Finally, it is shown that the conformal field equations provide a very powerful method within numerical relativity to study global problems such as gravitational wave propagation and detection.

Today, we understand that prenatal alcohol exposure induces a variety of adverse effects on physical, neurological, and behavioral development. Research supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) has contributed to the identification of the range and prevalence of fetal alcohol spectrum disorders (FASD), as well as methods for prevention and treatment of FASD. The worldwide prevalence and high personal and societal costs of FASD speak to the importance of this research. This article briefly examines some of the ways that NIAAA has contributed to our understanding of FASD, the challenges that we still face, and how this research is translated into changes in public policy.

In discussions about science education, we often hear and read references to two eras of reform: the first associated with launching of Sputnik in October of 1957 and the second prompted by the publication of Nation at Risk in 1983. Having been deeply involved in the first science project of the first era, namely the Physical Science Study Committee (PSSC) course in physics, now in its seventh edition, and following today's activities closely, I will try to describe the "what's" and "how's" of the PSSC as a representative of the first era and to compare them with today's reform.

A decade review of publications in Families, Systems, & Health: 2005-2015.

PubMed

Mendenhall, Tai J; Li, Yiting; Schulz, Catherine L

2016-09-01

The purpose of this investigation was to review recent publication content and trends in Families, Systems, & Health ( FSH ). How do the journal’s articles reflect current and emerging challenges in health care? We hope that our findings can guide special issues and content foci. All work published in FSH between 2005 and 2015 was included (n = 452); each piece was coded for article type, general foci, and specific foci. The most common type of article published over the 10-year time frame was research reports (43%; n = 195), followed by other types (e.g., tribute pieces, poems), commentaries, conceptual/theory papers, literature reviews, and case studies. The most common general focus included family health and/or functioning (28%; n = 128). The most common specific foci centered on children (15%; n = 55). Common themes found in FSH ’s most frequently cited publications included family relationships in care, chronic physical illnesses, and mental health. Marked trends in journal content included increases in articles targeting family health and/or functioning and primary care and decreased attention to theory. FSH’s emphasis on research reports to inform current and evolving interventions that target contemporary health challenges suggests that the journal is keeping stride with the most pressing issues in health care today. Future special issues can continue to serve and meet these needs. FSH’s robust inclusion of other article types sustains the journal’s mission to advance multiple ways of understanding health-care phenomena.

Ancient Chinese capital models — Measurement system in urban planning —

PubMed Central

FUNO, Shuji

2017-01-01

Measurement systems are very important in urban design. This article reviews the theories of grid plans, particularly with respect to the spatial formations of ancient capital cities in Asia, and clarifies three Chinese Capital Models. The “Zhōu lǐ” Capital Model (Z) is based on the ancient text “Zhōu lǐ” that makes mention of the ideal city. However, because the description of the physical plan of the city is very brief and includes contradictory elements, conclusions regarding the specifics of the city design are extremely difficult to reach. This article proposes the most appropriate Model (Z) as an architype of the ideal Chinese city. Interestingly, there are no excavated examples of Model (Z). The two existing models, the Chang’an Capital Model (C), which is well known as the model for ancient Japanese capitals like Heiankyo (the present Kyoto) and the Dà Yuán (Dadu) Capital Model (D), the model for the city that is today Beijing, are described as Variants I and II, with a focus on the land division system of bo (street blocks).

Corvids (Corvidae) play a major role in ornithological research. Because of their worldwide distribution, diversity and adaptiveness, they have been studied extensively. The aim of the Corvids Literature Database (CLD, http://www.corvids.de/cld) is to record all publications (citation format) on all extant and extinct Crows, Ravens, Jays and Magpies worldwide and tag them with specific keywords making them available for researchers worldwide. The self-maintained project started in 2006 and today comprises 8000 articles, spanning almost 500 years. The CLD covers publications from 164 countries, written in 36 languages and published by 8026 authors in 1503 journals (plus books, theses and other publications). Forty-nine percent of all records are available online as full-text documents or deposited in the physical CLD archive. The CLD contains 442 original corvid descriptions. Here, we present a metadata assessment of articles recorded in the CLD including a gap analysis and prospects for future research. Database URL: http://www.corvids.de/cld. © The Author(s) 2016.

75th Anniversary of `Existence of Electromagnetic-Hydrodynamic Waves'

NASA Astrophysics Data System (ADS)

Russell, Alexander J. B.

2018-05-01

We have recently passed the 75th anniversary of one of the most important results in solar and space physics: Hannes Alfvén's discovery of Alfvén waves and the Alfvén speed. To celebrate the anniversary, this article recounts some major episodes in the history of magnetohydrodynamic (MHD) waves. Following an initially cool reception, Alfvén's ideas were propelled into the spotlight by Fermi's work on cosmic rays, the new mystery of coronal heating, and, as scientific perception of interplanetary space shifted dramatically and the space race started, detection of Alfvén waves in the solar wind. From then on, interest in MHD waves boomed, laying the foundations for modern remote observations of MHD waves in the Sun, coronal seismology, and some of today's leading theories of coronal heating and solar wind acceleration. In 1970, Alfvén received the Nobel Prize for his work in MHD, including these discoveries. The article concludes with some reflection about what the history implies about the way we do science, especially the advantages and pitfalls of idealised mathematical models.

Retention of retrospective print journals in the digital age: trends and analysis

PubMed Central

Kaplan, Richard; Steinberg, Marilyn; Doucette, Joanne

2006-01-01

Purpose: The issue of retaining retrospective print journals is examined in light of the shift to electronic titles, the reallocation of library budgets from print to electronic, and the changing research practices of today's library users. This article also examines the evolving role of the physical library and its impact on space allocation. Methods: To determine current practice and opinion, a survey of health sciences librarians and academic librarians was conducted. To demonstrate the use patterns of older journal issues, citation analyses and interlibrary loan statistics were examined. Results: All methods indicate that recent material is accessed more frequently than older material, with a significant drop in use of materials greater than 15 years old. Materials greater than 20 years old constituted less than 5% of interlibrary loans and less than 9% of articles noted in the citation analysis. Conclusions: It is possible to eliminate older years of a print journal collection without a large impact on the needs of researchers. Librarians' preference to maintain full runs of journal titles may be motivated by reasons outside of actual usage or patrons needs. PMID:17082829

Resources and approaches for teaching physics to pre-health and life science majors

NASA Astrophysics Data System (ADS)

Widenhorn, Ralf

2014-03-01

As science is advancing, the skill set for a physician or medical researcher today and in the future is very different than it has been in the past. As an example, the American Association of Medical Colleges revised the Medical College Admissions Test (MCAT) to reflect this dynamic environment. Because of these changes, the needs of students entering into these professions are often not met by a traditional physics course. Developing curriculum for an introductory physics course that helps to prepare life science and pre-health students can be challenging for many physics instructors who lack a strong foundation in biology or medicine. This presentation will address various approaches that physics instructors without a background in life sciences can use to successfully teach an introductory physics course for life science and pre-heath students. For these courses, an online resource may be a useful tool. Online resources already exist today, but their utility relies on active engagement and sharing of teaching material by physics instructors possessing a background in both physics and the life sciences. This talk will address ways for the biomedical physics community to contribute to this effort.

Current trends in multimodality treatment of esophageal and gastroesophageal junction cancer - Review article.

PubMed

Klevebro, Fredrik; Ekman, Simon; Nilsson, Magnus

2017-09-01

Multimodality treatment has now been widely introduced in the curatively intended treatment of esophageal and gastroesophageal junction cancer. We aim to give an overview of the scientific evidence for the available treatment strategies and to describe which trends that are currently developing. We conducted a review of the scientific evidence for the different curatively intended treatment strategies that are available today. Relevant articles of randomized controlled trials, cohort studies, and meta analyses were included. After a systematic search of relevant papers we have included 64 articles in the review. The results show that adenocarcinomas and squamous cell carcinomas of the esophagus and gastroesophageal junction are two separate entities and should be analysed and studied as two different diseases. Neoadjuvant treatment followed by surgical resection is the gold standard of the curatively intended treatment today. There is no scientific evidence to support the use of chemoradiotherapy over chemotherapy in the neoadjuvant setting for esophageal or junctional adenocarcinoma. There is reasonable evidence to support definitive chemoradiotherapy as a treatment option for squamous cell carcinoma of the esophagus. The evidence base for curatively intended treatments of esophageal and gastroesophageal junction cancer is not very strong. Several on-going trials have the potential to change the gold standard treatments of today. Copyright © 2017 Elsevier Ltd. All rights reserved.

Semiconductor devices for entangled photon pair generation: a review

NASA Astrophysics Data System (ADS)

Orieux, Adeline; Versteegh, Marijn A. M.; Jöns, Klaus D.; Ducci, Sara

2017-07-01

Entanglement is one of the most fascinating properties of quantum mechanical systems; when two particles are entangled the measurement of the properties of one of the two allows the properties of the other to be instantaneously known, whatever the distance separating them. In parallel with fundamental research on the foundations of quantum mechanics performed on complex experimental set-ups, we assist today with bourgeoning of quantum information technologies bound to exploit entanglement for a large variety of applications such as secure communications, metrology and computation. Among the different physical systems under investigation, those involving photonic components are likely to play a central role and in this context semiconductor materials exhibit a huge potential in terms of integration of several quantum components in miniature chips. In this article we review the recent progress in the development of semiconductor devices emitting entangled photons. We will present the physical processes allowing the generation of entanglement and the tools to characterize it; we will give an overview of major recent results of the last few years and highlight perspectives for future developments.

I used frequency sparklines of words, matching one of four archetypal shapes (level, rise, fall, and rise-and-fall) to identify significant words. Most significant words fell into the categories of environment, management, technology, and research. Based on word usage changes, the following trends are revealed: Compared to 1961, today's medical librarians are more concerned with digital information, not physical packages. We prefer information to be evidence-based. We focus more on health than medicine. We are reaching out to new constituents, sometimes leaving our building to do so. Teaching has become important for us. We run our libraries more like businesses, using constantly changing technology. We are publishing more research articles. Although these words were chosen by individual authors to tell their particular stories, in the aggregate, our words reveal our story of change in our profession.

FOREWORD: Fifty years of atomic time-keeping: 1955 to 2005

NASA Astrophysics Data System (ADS)

Quinn, Terry

2005-06-01

The year 2005 is the centenary of Einstein's four famous papers that were published in 1905. This anniversary is being widely celebrated all over the world and, indeed, 2005 has been dubbed World Year of Physics. The year 2005, however, also marks the fiftieth anniversary of the first operation of Essen and Parry's caesium beam atomic frequency standard at the NPL in May 1955. While Einstein's papers signalled a revolution in physics and in our understanding of the natural world, the first atomic clock signalled a revolution in time-keeping that has become, among other things, one of the most powerful tools in pushing back the frontiers of Einstein's theories of special and general relativity. The atomic clock has also had consequences for navigation comparable to those brought about by Harrison's mechanical clocks almost exactly two hundred years before. Harrison's H3 was completed in 1757 and H4 in 1759. The atomic clock, and the creation of an atomic time scale that quickly followed, led ten years later to the adoption of an atomic definition for the SI second in Resolution 1 of the 13th General Conference on Weights and Measures, 1967/68. This marked the end of time-keeping based on the movements of the heavenly bodies that had beaten the rhythm of the days and the seasons since the dawn of human civilization. Fifty years on is a good occasion to look back, to look forward and at the same time to examine where we are today, in terms of measuring time. While we still arrange for our atomic clocks to show noon when the sun is overhead on the Greenwich meridian, everything else has changed in the fifty years since 1955. In this special issue of Metrologia the reader will find articles on the development of the atomic clock, its theory and practice, how the first atomic time scale was devised and formally introduced and how we maintain atomic time today, as well as articles looking forward to even more accurate clocks and time scales. Included also are articles on the commercial development of atomic clocks of various types and on some of their applications. At the beginning there is a deliberate emphasis on the history of the introduction of atomic time, including the technical problems to be resolved and the personalities involved. You will see that it includes one article based on notes left by Louis Essen himself, for which we are most grateful to his son, Mr Ray Essen, for permission to use them and to Dale Henderson of the NPL, who arranged them for publication here. I hope that this issue will stand as a reference for years to come and I am most grateful to all those who have contributed. I also wish to thank most particularly Norman Ramsey, whose name is indelibly associated with atomic clocks, for having contributed the first article to this special issue.

Purnell, Larry

2002-07-01

This article provides an overview of the Purnell Model for Cultural Competence and the assumptions on which the model is based. The 12 domains comprising the organizing framework are briefly described along with the primary and secondary characteristics of culture, which determine variations in values, beliefs, and practices of an individual's cultural heritage. All health care providers in any practice setting can use the model, which makes it especially desirable in today's team-oriented health care environment. The model has been used by nurses, physicians, and physical and occupational therapists in practice, education, administration, and research in Australia, Belgium, Canada, Central America, Great Britain, Korea, South America, and Sweden. The model has also been translated into Flemish, French, Korean, and Spanish. Although the model is only 4 years old, it shows promise for becoming a major contribution to transcultural nursing and health care.

New hermetic sealing material for vacuum brazing of stainless steels

NASA Astrophysics Data System (ADS)

Hildebrandt, S.; Wiehl, G.; Silze, F.

2016-03-01

For vacuum brazing applications such as in vacuum interrupter industry Hermetic Sealing Materials (HSM) with low partial pressure are widely used. AgCu28 dominates the hermetic sealing market, as it has a very good wetting behavior on copper and metallized ceramics. Within recent decades wetting on stainless steel has become more and more important. However, today the silver content of HSMs is more in focus than in the past decades, because it has the biggest impact on the material prices. Umicore Technical Materials has developed a new copper based HSM, CuAg40Ga10. The wettability on stainless steel is significantly improved compared to AgCu28 and the total silver content is reduced by almost 44%. In this article the physical properties of the alloy and its brazed joints will be presented compared to AgCu28.

The Built Environment and Its Relationship to the Public’s Health: The Legal Framework

PubMed Central

Perdue, Wendy Collins; Stone, Lesley A.; Gostin, Lawrence O.

2003-01-01

The built environment significantly affects the public’s health. This was most obvious when infectious disease was the primary public health threat during the industrial revolution; unsanitary conditions and overcrowded urban areas facilitated the spread of infection. However, even today in the age of chronic diseases there remains an important connection between population health and the built environment. Physical spaces can expose people to toxins or pollutants and influence lifestyles that contribute to diabetes, coronary vascular disease, and asthma. Public health advocates can help shape the design of cities and suburbs in ways that improve public health, but to do so effectively they need to understand the legal framework. This article reviews the connection between public health and the built environment and then describes the legal pathways for improving the design of our built environment. PMID:12948949

The Development of Chromosome Microdissection and Microcloning Technique and its Applications in Genomic Research

PubMed Central

Zhou, Ruo-Nan; Hu, Zan-Min

2007-01-01

The technique of chromosome microdissection and microcloning has been developed for more than 20 years. As a bridge between cytogenetics and molecular genetics, it leads to a number of applications: chromosome painting probe isolation, genetic linkage map and physical map construction, and expressed sequence tags generation. During those 20 years, this technique has not only been benefited from other technological advances but also cross-fertilized with other techniques. Today, it becomes a practicality with extensive uses. The purpose of this article is to review the development of this technique and its application in the field of genomic research. Moreover, a new method of generating ESTs of specific chromosomes developed by our lab is introduced. By using this method, the technique of chromosome microdissection and microcloning would be more valuable in the advancement of genomic research. PMID:18645627

Martínez-Frías, Jesús; Hochberg, David; Rull, Fernando

2006-02-01

The World Year of Physics (2005) is an international celebration to commemorate the 100th anniversary of Einstein's "Annus Mirabilis." The United Nations has officially declared 2005 as the International Year of Physics. However, the impact of Einstein's ideas was not restricted to physics. Among numerous other disciplines, Einstein also made significant and specific contributions to Earth Sciences. His geosciences-related letters, comments, and scientific articles are dispersed, not easily accessible, and are poorly known. The present review attempts to integrate them as a tribute to Einstein in commemoration of this centenary. These contributions can be classified into three basic areas: geodynamics, geological (planetary) catastrophism, and fluvial geomorphology. Regarding geodynamics, Einstein essentially supported Hapgood's very controversial theory called Earth Crust Displacement. With respect to geological (planetary) catastrophism, it is shown how the ideas of Einstein about Velikovsky's proposals evolved from 1946 to 1955. Finally, in relation to fluvial geodynamics, the review incorporates the elegant work in which Einstein explains the formation of meandering rivers. A general analysis of his contributions is also carried out from today's perspective. Given the interdisciplinarity and implications of Einstein's achievements to multiple fields of knowledge, we propose that the year 2005 serve, rather than to confine his universal figure within a specific scientific area, to broaden it for a better appreciation of this brilliant scientist in all of his dimensions.

NEW HORIZONS IN SENSOR DEVELOPMENT

PubMed Central

Intille, Stephen S.; Lester, Jonathan; Sallis, James F.; Duncan, Glen

2011-01-01

Background Accelerometery and other sensing technologies are important tools for physical activity measurement. Engineering advances have allowed developers to transform clunky, uncomfortable, and conspicuous monitors into relatively small, ergonomic, and convenient research tools. New devices can be used to collect data on overall physical activity and in some cases posture, physiological state, and location, for many days or weeks from subjects during their everyday lives. In this review article, we identify emerging trends in several types of monitoring technologies and gaps in the current state of knowledge. Best practices The only certainty about the future of activity sensing technologies is that researchers must anticipate and plan for change. We propose a set of best practices that may accelerate adoption of new devices and increase the likelihood that data being collected and used today will be compatible with new datasets and methods likely to appear on the horizon. Future directions We describe several technology-driven trends, ranging from continued miniaturization of devices that provide gross summary information about activity levels and energy expenditure, to new devices that provide highly detailed information about the specific type, amount, and location of physical activity. Some devices will take advantage of consumer technologies, such as mobile phones, to detect and respond to physical activity in real time, creating new opportunities in measurement, remote compliance monitoring, data-driven discovery, and intervention.

Seestrom, Susan

2017-01-01

The Manhattan Project had to solve difficult challenges in physics and materials science. During the cold war a large nuclear stockpile was developed. In both cases, the approach was largely empirical. Today that stockpile must be certified without nuclear testing, a task that becomes more difficult as the stockpile ages. I will discuss the role of modern accelerator based experiments, such as x-ray radiography, proton radiography, neutron and nuclear physics experiments, in stockpile stewardship. These new tools provide data of exceptional sensitivity and are answering questions about the stockpile, improving our scientific understanding, and providing validation for the computer simulations that are relied upon to certify todays' stockpile.

Friction, force chains, and falling fruit

Krim, Jacqueline; Behringer, Robert

2010-03-01

Friction is of great concern from both a national security and quality-of-life point of view, and the economic impact of energy efficiency, wear, and manufacturing cannot be underestimated. Theorists have always believed that friction plays a great role in avalanche-like collapse of a granular piles, but the predictions have proven difficult to test. We devised an experimentally controlled way to prove it, accessible to all who dare try, and report on it here [1,2]. With the aid of a middle school assistant, we studied and filmed piles of apples, oranges, and onions as one or more pieces of fruit were removed. Among other things, we discovered that increasing the friction of the onions (by peeling them) vastly decreased the likelihood of collapse. Our work includes videos written by, produced, and starring our seventh grade assistant, some of which are posted on the Physics Today YouTube channel [1] and featured in the Sept. 2009 issue of Physics Today [2].

Solar neutrino spectroscopy

NASA Astrophysics Data System (ADS)

Wurm, Michael

2017-04-01

More than forty years after the first detection of neutrinos from the Sun, the spectroscopy of solar neutrinos has proven to be an on-going success story. The long-standing puzzle about the observed solar neutrino deficit has been resolved by the discovery of neutrino flavor oscillations. Today's experiments have been able to solidify the standard MSW-LMA oscillation scenario by performing precise measurements over the whole energy range of the solar neutrino spectrum. This article reviews the enabling experimental technologies: On the one hand multi-kiloton-scale water Cherenkov detectors performing measurements in the high-energy regime of the spectrum, on the other end ultrapure liquid-scintillator detectors that allow for a low-threshold analysis. The current experimental results on the fluxes, spectra and time variation of the different components of the solar neutrino spectrum will be presented, setting them in the context of both neutrino oscillation physics and the hydrogen fusion processes embedded in the Standard Solar Model. Finally, the physics potential of state-of-the-art detectors and a next generation of experiments based on novel techniques will be assessed in the context of the most interesting open questions in solar neutrino physics: a precise measurement of the vacuum-matter transition curve of electron-neutrino oscillation probability that offers a definitive test of the basic MSW-LMA scenario or the appearance of new physics; and a first detection of neutrinos from the CNO cycle that will provide new information on solar metallicity and stellar physics.

This article describes benefits of filtration advances which include fewer forced outages, faster startups and reduced bearing wear. The importance of clean lubricating oil for turbines has been recognized for a long time, and almost all generating plants use some type of filtration system. Many older technologies and systems cannot remove enough of the contaminants to meet the needs of today`s turbines and operating conditions. Newer filtration technologies, such as multiphase filtration systems incorporating pressure coalescence filters to remove water, can reduce contaminants to levels that will help prevent unscheduled or forced outages, allow faster startups after an ongoing outage,more » and reduce wear of bearings and other components. Such preventive measures are more important than ever because of today`s increased competition and emphasis on cost control.« less

Stone disease has afflicted mankind since centuries; records from ancient civilisations of India and Egypt have shown stones in human bodies. The scientific mind of humans has always made smart endeavours to remove the kidney stones. From large instruments made like the beaks of different animals and birds in 600 BC (Indian civilisation) to extremely sophisticated and miniaturised endoscopic intruments of today the human race has travelled a long way. The theme has always been to remove the stones with minimal morbidity and mortality and with minimum pain to the patient. The article takes you through the journey of instruments used in 600 BC until today. The story of instrumentation is a symbiosis of the medical minds along with engineering advances. The story of miniaturisation could not have moved further without the development of lasers, fiberoptics and sophisticated cameras. As the field stands today, we remove more complex stones by larger endoscopic intervention and smaller stones by miniaturised instruments. The article discusses all the merits and shortcomings of various techniques: from open surgery to standard PCNL to Mini PCNL to Ultra- Mini PCNL to Micro-PCNL.

The HART II International Workshop: An Assessment of the State-of-the-Art in Comprehensive Code Prediction

2013-01-01

Significant advancements in computational fluid dynamics (CFD) and their coupling with computational structural dynamics (CSD, or comprehensive codes) for rotorcraft applications have been achieved recently. Despite this, CSD codes with their engineering level of modeling the rotor blade dynamics, the unsteady sectional aerodynamics and the vortical wake are still the workhorse for the majority of applications. This is especially true when a large number of parameter variations is to be performed and their impact on performance, structural loads, vibration and noise is to be judged in an approximate yet reliable and as accurate as possible manner. In this article, the capabilities of such codes are evaluated using the HART II International Workshop database, focusing on a typical descent operating condition which includes strong blade-vortex interactions. A companion article addresses the CFD/CSD coupled approach. Three cases are of interest: the baseline case and two cases with 3/rev higher harmonic blade root pitch control (HHC) with different control phases employed. One setting is for minimum blade-vortex interaction noise radiation and the other one for minimum vibration generation. The challenge is to correctly predict the wake physics-especially for the cases with HHC-and all the dynamics, aerodynamics, modifications of the wake structure and the aero-acoustics coming with it. It is observed that the comprehensive codes used today have a surprisingly good predictive capability when they appropriately account for all of the physics involved. The minimum requirements to obtain these results are outlined.

Progress in medicine: autonomy, oughtonomy and nudging.

PubMed

Devisch, Ignaas

2011-10-01

In this article, I argue that we need a new perspective in the debate on autonomy in medicine, to understand many of the problems we face today - dilemmas that are situated at the intersection of autonomy and heteronomy, such as why well informed and autonomous people make unhealthy lifestyle choices. If people do not choose what they want, this is not simply caused by their lack of character or capability, but also by the fact that absolute autonomy is impossible; autonomous individuals are 'contaminated' by heteronymous aspects, by influences from 'outside'. Consequently, there are many good reasons to question the widely accepted hierarchical opposition of autonomy (progress) versus heteronomy (paternalism) in medicine. In an earlier article an analysis is made of the neologism 'oughtonomy' to support the thesis that when it comes down to human existence, autonomy and heteronomy are intertwined, rather than being merely opposites. In this article, I reflect upon how social conditions might improve our 'choice architecture', what Thaler & Sunstein have called 'nudging': how to change individual health choices without being paternalistic? I explore the extent to which both oughtonomy and nudging are able to challenge the question of autonomy in today's medicine. Autonomy may and should be a shared target in today's medicine, but we should never forget that it is always intertwined with heteronomy. Starting from this perspective, progress in medicine demands far more than the increase of autonomy. © 2011 Blackwell Publishing Ltd.

The intentional brain--a short history of neuropsychiatry.

PubMed

Trimble, Michael

2016-06-01

Neuropsychiatry has had different meanings at different times in the history of clinical neuroscience. In this article, the origins of what has become today's neuropsychiatry are briefly explored, hopefully revealing a number of pioneers of the discipline, some of the names being familiar to many readers, others however being less recognized or even unknown to those who today would wish to carry the moniker of a neuropsychiatrist. It explores the rise of what I refer to as modern or today's neuropsychiatry, and empathizes a phenomenological approach to clinical understanding, and the fact that neuropsychiatry it is a discipline in its own right and not just a wing of psychiatry or a bridge between neurology and psychiatry.

Academic dishonesty today, unethical practices tomorrow?

PubMed

LaDuke, Rebekah D

2013-01-01

The purpose of this article was to review the most current published literature on the topics of academic dishonesty, unethical professional practices, and research that studied the correlation between these 2 areas of interest. Literature was retrieved by utilizing key words such as academic dishonesty, cheating, workplace dishonesty, and unethical behavior. Multiple research databases were used and a reference librarian in locating relevant research studies resulting in 16 research articles reviewed and 7 articles referenced within the literature review. Upon completion, it became apparent that nursing educators should be concerned that nursing students found to be academically dishonest today may have a higher incidence of displaying unethical practices as a registered nurse tomorrow. It also became clear that the nursing profession needs to conduct its own research in this field to verify findings discovered by other professions such as engineering, business, and psychology. Finally, recommendations were given on how nursing educators should handle the topic of ethics in nursing programs. Copyright © 2013 Elsevier Inc. All rights reserved.

100 Years of Attempts to Transform Physics Education

NASA Astrophysics Data System (ADS)

Otero, Valerie K.; Meltzer, David E.

2016-12-01

As far back as the late 1800s, U.S. physics teachers expressed many of the same ideas about physics education reform that are advocated today. However, several popular reform efforts eventually failed to have wide impact, despite strong and enthusiastic support within the physics education community. Broad-scale implementation of improved instructional models today may be just as elusive as it has been in the past, and for similar reasons. Although excellent instructional models exist and have been available for decades, effective and scalable plans for transforming practice on a national basis have yet to be developed and implemented. Present-day teachers, education researchers, and policy makers can find much to learn from past efforts, both in their successes and their failures. To this end, we present a brief outline of some key ideas in U.S. physics education during the past 130 years. We address three core questions that are prominent in the literature: (a) Why and how should physics be taught? (b) What physics should be taught? (c) To whom should physics be taught? Related issues include the role of the laboratory and attempts to make physics relevant to everyday life. We provide here only a brief summary of the issues and debates found in primary-source literature; an extensive collection of historical resources on physics education is available at https://sites.google.com/site/physicseducationhistory/home.

Analytical general solutions for static wormholes in f(R,T) gravity

NASA Astrophysics Data System (ADS)

Moraes, P. H. R. S.; Correa, R. A. C.; Lobato, R. V.

2017-07-01

Originally proposed as a tool for teaching the general theory of relativity, wormholes are today approached in many different ways and are seeing as an efficient alternative for interstellar and time travel. Attempts to achieve observational signatures of wormholes have been growing as the subject has become more and more popular. In this article we investigate some f(R,T) theoretical predictions for static wormholes, i.e., wormholes whose throat radius can be considered a constant. Since the T-dependence in f(R,T) gravity is due to the consideration of quantum effects, a further investigation of wormholes in such a theory is well motivated. We obtain the energy conditions of static wormholes in f(R,T) gravity and apply an analytical approach to find their physical and geometrical solutions. We highlight that our results are in agreement with previous solutions and assumptions presented in the literature.

Using remote sensing and imagery exploitation to monitor the dynamics of East Timbalier Island, LA: 2000-2010

In 1999, the National Oceanic and Atmospheric Administration-National Marine Fisheries Service and the State of Louisiana jointly undertook the restoration of East Timbalier, a barrier island along a sediment-starved portion of the Gulf of Mexico coast of Louisiana. High-resolution overhead imagery was used to monitor the course of this restoration effort. This article describes the changes in area and movement of East Timbalier Island and compares these changes with the previous measurements. Between 2000 and 2010, East Timbalier Island lost 52–66% of its area and moved northwards 12–105 m/year. The area of East Timbalier Island is less today than at any time since 1887. Understanding of the physical processes in nature that control the size, shape and movement of the island, as well as the human impacts that have hastened its degradation, is critical for accomplishing any future restoration.

GPS as a tool used in tourism as illustrated by selected mobile applications

NASA Astrophysics Data System (ADS)

Szark-Eckardt, Mirosława

2017-11-01

Mobile technologies have permanently changed our way of life. Their availability, common use and introducing to virtually all areas of human activity means that we can call present times the age of mobility [1]. Mobile applications based on the GPS module belong to the most dynamically developing apps as particularly reflected in tourism. A multitude of applications dedicated to different participants of tourism, which can be operated by means of smartphones or simple GPS trackers, are encouraging more people to reach for this kind of technology perceiving it as a basic tool used in today's tourism. Due to an increasingly wider access to mobile applications, not only more dynamic development of tourism itself can be noticed, but also the growth of healthy behaviours that comprise a positive "side effect" of tourism based on mobile technology. This article demonstrates a correlation between health and physical condition of the population and the use of mobile applications.

Heinrich Hertz and Philipp Lenard: Two Distinguished Physicists, Two Disparate Men

NASA Astrophysics Data System (ADS)

Mulligan, Joseph F.

1999-12-01

Heinrich Hertz (1857-1894) and Philipp Lenard (1862-1947) both had distinguished careers as physicists. They were together in Bonn from April 1891 to January 1894, Hertz as Director of the Bonn Physics Institute, and Lenard as his assistant. Each did important experimental work on cathode rays and the photoelectric effect, and in 1905 Lenard received the Nobel Prize for his work in these fields. Lenard had great respect and admiration for Hertz before going to Bonn and while there, but gradually allowed his esteem for his mentor (who died in 1894) to diminish as Lenard became increasingly anti-Semitic and involved in National Socialism and the Nazi movement. This article illustrates how differences in their characters and personalities, together with the tragic events of the Great War and its aftermath, resulted in Hertz deservedly being much more highly regarded today both as a physicist and as a man than is Lenard.

Hydroxylated polychlorinated biphenyls in the environment: sources, fate, and toxicities.

PubMed

Tehrani, Rouzbeh; Van Aken, Benoit

2014-05-01

Hydroxylated polychlorinated biphenyls (OH-PCBs) are produced in the environment by the oxidation of PCBs through a variety of mechanisms, including metabolic transformation in living organisms and abiotic reactions with hydroxyl radicals. As a consequence, OH-PCBs have been detected in a wide range of environmental samples, including animal tissues, water, and sediments. OH-PCBs have recently raised serious environmental concerns because they exert a variety of toxic effects at lower doses than the parent PCBs and they are disruptors of the endocrine system. Although evidence about the widespread dispersion of OH-PCBs in various compartments of the ecosystem has accumulated, little is currently known about their biodegradation and behavior in the environment. OH-PCBs are, today, increasingly considered as a new class of environmental contaminants that possess specific chemical, physical, and biological properties not shared with the parent PCBs. This article reviews recent findings regarding the sources, fate, and toxicities of OH-PCBs in the environment.

Beyond motivation: job and work design for development, health, ambidexterity, and more.

PubMed

Parker, Sharon K

2014-01-01

Much research shows it is possible to design motivating work, which has positive consequences for individuals and their organizations. This article reviews research that adopts this motivational perspective on work design, and it emphasizes that it is important to continue to refine motivational theories. In light of continued large numbers of poor-quality jobs, attention must also be given to influencing practice and policy to promote the effective implementation of enriched work designs. Nevertheless, current and future work-based challenges mean that designing work for motivation is necessary but insufficient. This review argues that work design can be a powerful vehicle for learning and development, for maintaining and enhancing employees' physical and mental health, and for achieving control and flexibility simultaneously (for example, in the form of ambidexterity); all these outcomes are important given the challenges in today's workplaces. The review concludes by suggesting methodological directions.

2007-07-01

The prevalence and cost of chronic pain is a major physical and mental health care problem in the United States today. As a result, there has been a recent explosion of research on chronic pain, with significant advances in better understanding its etiology, assessment, and treatment. The purpose of the present article is to provide a review of the most noteworthy developments in the field. The biopsychosocial model is now widely accepted as the most heuristic approach to chronic pain. With this model in mind, a review of the basic neuroscience processes of pain (the bio part of biopsychosocial), as well as the psychosocial factors, is presented. This spans research on how psychological and social factors can interact with brain processes to influence health and illness as well as on the development of new technologies, such as brain imaging, that provide new insights into brain-pain mechanisms.

Frustration by design

DOE PAGES

Gilbert, Ian; Nisoli, Cristiano; Schiffer, Peter

2016-07-01

Geometrical frustration is a condition that occurs when a material’s lattice geometry precludes minimizing the energy of all the interactions among pairs of neighbors simultaneously. Moreover, the simplest example is three antiferromagnetically coupled Ising spins, pointing up or down, on the corners of an equilateral triangle: It is also impossible to arrange the spins so that each pair is antiparallel. In more complex magnetic lattices, the frustrated state can arise from the combination of lattice geometry and the strength and sign of the interactions among the magnetic dipole moments.1 (See the article by Roderich Moessner and Art Ramirez, Physics Today,more » February 2006, page 24.) A wide variety of exotic and collective phenomena sometimes arises from the competing interactions. One prime example is spin liquids, materials in which the local atomic moments fluctuate down to the lowest accessible temperatures and never settle into a static ground-state configuration.« less

2014-06-01

Superionic solids an area of multidisciplinary research activity, incorporates to study the physical, chemical and technological aspects of rapid ion movements within the bulk of the special class of ionic materials. It is an emerging area of materials science, as these solids show tremendous technological scopes to develop wide variety of solid state electrochemical devices such as batteries, fuel cells, supercapacitors, sensors, electrochromic displays (ECDs), memories, etc. These devices have wide range of applicabilities viz. power sources for IC microchips to transport vehicles, novel sensors for controlling atmospheric pollution, new kind of memories for computers, smart windows/display panels, etc. The field grew with a rapid pace since then, especially with regards to designing new materials as well as to explore their device potentialities. Amongst the known superionic solids, fast Ag+ ion conducting crystalline solid electrolytes are attracted special attention due to their relatively higher room temperature conductivity as well as ease of materials handling/synthesis. Ion conduction in these electrolytes is very much interesting part of today. In the present review article, the ion conducting phenomenon and some device applications of crystalline/polycrystalline superionic solid electrolytes have been reviewed in brief. Synthesis and characterization tools have also been discussed in the present review article.

[Medicine, philosophy and the scientific revolution. A bibliographical survey].

PubMed

Crignon, Claire; Antoine-Mahut, Delphine

2014-01-01

This article examines the place that has been reserved for medicine in the historiography of the sciences. More precisely, it focuses on the motifs that have lead historians of science to grant only a minor role to medicine within the movement commonly designated by the notion of the "scientific revolution". Among those motifs, the persistent and late application of teleological schemas in the thinking of the biological and the difficulties in "mathematizing" anatomy are often invoked. Starting with an overview of the critical literature on the topic, this bibliographical essay shows how the situation has changed over the last decades. The opposition between, on the one hand, the physical sciences founded on a model of mechanistic explanation of nature and, on the other hand, the life sciences that remained guided by a finalist mode of thinking are today much put into question. What we find today is more open reflection on the diversity of "models" for understanding the living, and on how to integrate them into more complex schemas than those that simply oppose mechanism and teleology. The essay is finally based on discussions and debates among medical doctors and philosophers in the modern period, and insists on the importance of studying this "medico-philosophical" tradition in order to avoid reconstructing a posteriori a mythical history that trends to consecrate a single model of rationality.

Our words, our story: a textual analysis of articles published in the Bulletin of the Medical Library Association/Journal of the Medical Library Association from 1961 to 2010*

PubMed Central

Funk, Mark E.

2013-01-01

Purpose: This lecture explores changes in the medical library profession over the last fifty years, as revealed by individual word usage in a body of literature. Methods: I downloaded articles published in the Bulletin of the Medical Library Association and Journal of the Medical Library Association between 1961 and 2000 to create an electronic corpus and tracked annual frequency of individual word usage. I used frequency sparklines of words, matching one of four archetypal shapes (level, rise, fall, and rise-and-fall) to identify significant words. Results: Most significant words fell into the categories of environment, management, technology, and research. Based on word usage changes, the following trends are revealed: Compared to 1961, today's medical librarians are more concerned with digital information, not physical packages. We prefer information to be evidence-based. We focus more on health than medicine. We are reaching out to new constituents, sometimes leaving our building to do so. Teaching has become important for us. We run our libraries more like businesses, using constantly changing technology. We are publishing more research articles. Conclusions: Although these words were chosen by individual authors to tell their particular stories, in the aggregate, our words reveal our story of change in our profession. PMID:23405042

To address the most dynamic and current issues concerning today's treatment options and promising research efforts regarding treatment for age-related macular degeneration. This review is aimed to serve as a practical reference for more in-depth reviews on the subject. An online review of the database PubMed and Ovid were performed, searching for the key words age-related macular degeneration, AMD, VEGF, treatment, PDT, steroids, bevacizumab, ranibizumab, VEGF-trap, radiation, combined therapy, as well as their compound phrases. The search was limited to articles published since 1985. All returned articles were carefully screened, and their references were manually reviewed for additional relevant data. The web page www.clinicaltrials.gov was also accessed in search of relevant research trials. A total of 363 articles were reviewed, including 64 additional articles extracted from the references. At the end, only 160 references were included in this review. Treatment for age-related macular degeneration is a very dynamic research field. While current treatments are mainly aimed at blocking vascular endothelial growth factor, future treatments seek to prevent vision loss because of scarring. Promising efforts have been made to address the dry form of the disease, which has lacked effective treatment.

Socioeconomic status and the health of youth: a multilevel, multidomain approach to conceptualizing pathways.

PubMed

Schreier, Hannah M C; Chen, Edith

2013-05-01

Previous research has clearly established associations between low socioeconomic status (SES) and poor youth physical health outcomes. This article provides an overview of the main pathways through which low SES environments come to influence youth health. We focus on 2 prevalent chronic health problems in youth today, asthma and obesity. We review and propose a model that encompasses (a) multiple levels of influence, including the neighborhood, family and person level; (b) both social and physical domains in the environment; and finally (c) dynamic relationships between these factors. A synthesis of existing research and our proposed model draw attention to the notion of adverse physical and social exposures in youth's neighborhood environments altering family characteristics and youth psychosocial and behavioral profiles, thereby increasing youth's risk for health problems. We also note the importance of acknowledging reciprocal influences across levels and domains (e.g., between family and child) that create self-perpetuating patterns of influence that further accentuate the impact of these factors on youth health. Finally, we document that factors across levels can interact (e.g., environmental pollution levels with child stress) to create unique, synergistic effects on youth health. Our model stresses the importance of evaluating influences on youth's physical health not in isolation but in the context of the broader social and physical environments in which youth live. Understanding the complex relationships between the factors that link low SES to youth's long-term health trajectories is necessary for the creation and implementation of successful interventions and policies to ultimately reduce health disparities.

2012-09-01

There are many external influences in today's market force that impair the relationship between the pain medicine specialist and the patient, and ultimately prevent optimal quality of care. This article explores the ethical challenges facing the pain medicine specialist in today's increasingly "business" environment and will offer solutions for maintaining the professionalism of pain medicine. Four commonly encountered bioethical principles in the practice of pain medicine are reviewed: beneficence, nonmaleficence, justice, and autonomy. The following ethical challenges of the pain medicine specialist are reviewed: practicing outside ones specialty area, practice characteristics, the consultant role, the economic lure of aggressive intervention, not evaluating for and treating comorbid psychopathology, reimbursement pressures, workers' compensation, and use of unproven methods. Solutions offered include collegial associations, social responsibility, legislative initiatives, pain education, interdisciplinary evaluation and treatment, improved relationships with third-party payers, reduced racial disparities, and ethics education. Ethics is the "roadmap" that enables the pain medicine specialist to navigate the increasingly murky waters of practicing pain management today by maintaining the professionalism necessary to combat today's "business" pressures.

A possible first use of the word astrobiology?

PubMed

Briot, Danielle

2012-12-01

The word astrobiology was possibly first used in 1935, in an article published in a French popular science magazine. The author was Ary J. Sternfeld (1905-1980), a pioneer of astronautics who wrote numerous scientific books and papers. The article is remarkable because his portrayal of the concept is very similar to the way it is used today. Here I review the 1935 article and provide a brief history of Sternfeld's life, which was heavily influenced by the tragic events of 20(th) century history.

The close and ineluctable links between anatomy and physical anthropology are explored. The relevance of many aspects of physical anthropology in the teaching of anatomy to medical and dental students is stressed. It is suggested that, since physical anthropology is one of the frontier fields in anatomical research today, it may help to attract personnel to anatomy departments which in most parts of the world are suffering from a serious shortage of suitably qualified people to teach gross anatomy.

Physics transforming the life sciences.

2014-10-08

Biological physics is clearly becoming one of the leading sciences of the 21st century. This field involves the cross-fertilization of ideas and methods from biology and biochemistry on the one hand and the physics of complex and far from equilibrium systems on the other. Here I want to discuss how biological physics is a new area of physics and not simply applications of known physics to biological problems. I will focus in particular on the new advances in theoretical physics that are already flourishing today. They will become central pieces in the creation of this new frontier of science.

How the Mid-Victorians Worked, Ate and Died†

PubMed Central

Clayton, Paul; Rowbotham, Judith

2009-01-01

Analysis of the mid-Victorian period in the U.K. reveals that life expectancy at age 5 was as good or better than exists today, and the incidence of degenerative disease was 10% of ours. Their levels of physical activity and hence calorific intakes were approximately twice ours. They had relatively little access to alcohol and tobacco; and due to their correspondingly high intake of fruits, whole grains, oily fish and vegetables, they consumed levels of micro- and phytonutrients at approximately ten times the levels considered normal today. This paper relates the nutritional status of the mid-Victorians to their freedom from degenerative disease; and extrapolates recommendations for the cost-effective improvement of public health today.

By its special mode of inquiry and its tantalizing successes, it has capturing the very spirit of the scientific method, and indeed it has been taken as a role model by other disciplines all the way from the "hard" ones to the social sciences. We shall then review how much we know today of the world of matter, both in term of its basic content and in the way it is structured. We will then present the dreams of today's theoretical physics as a way of penetrating into its psyche, discovering in this way its aspirations and longing in much the same way that a child's dreams tell us about his yearning and craving. Yet our understanding of matter has been going in the past decades through a crisis of sort. As a necessary antidote, we shall thus discuss the pitfalls of dreams pushed too far….

Student Nurse in the War Zone.

PubMed

2016-12-01

: Editor's note: From its first issue in 1900 through to the present day, AJN has unparalleled archives detailing nurses' work and lives over more than a century. These articles not only chronicle nursing's growth as a profession within the context of the events of the day, but they also reveal prevailing societal attitudes about women, health care, and human rights. Today's nursing school curricula rarely include nursing's history, but it's a history worth knowing. To this end, From the AJN Archives highlights articles selected to fit today's topics and times.In this month's article, from the September 1942 issue, senior nursing student Frances Carr writes vividly about life and work in Honolulu after Pearl Harbor. "Students… have had seared into their memories scenes of such horror as cannot be imagined…. When night fell, the nursing staff faced its first test of caring for hundreds of patients in a blackout that had to be absolute." And in this issue, see "Remembering Pearl Harbor at 75 Years," which tells the stories of five nurses from the Army and Navy Nurse Corps who were stationed nearby at the time of the attack.

Concept Assessment of a Fission Fragment Rocket Engine (FFRE) Propelled Spacecraft

NASA Technical Reports Server (NTRS)

Werka, Robert; Clark, Rod; Sheldon, Rob; Percy, Tom

2012-01-01

The March, 2012 issue of Aerospace America stated that ?the near-to-medium prospects for applying advanced propulsion to create a new era of space exploration are not very good. In the current world, we operate to the Moon by climbing aboard a Carnival Cruise Lines vessel (Saturn 5), sail from the harbor (liftoff) shedding whole decks of the ship (staging) along the way and, having reached the return leg of the journey, sink the ship (burnout) and return home in a lifeboat (Apollo capsule). Clearly this is an illogical way to travel, but forced on Explorers by today's propulsion technology. However, the article neglected to consider the one propulsion technology, using today's physical principles that offer continuous, substantial thrust at a theoretical specific impulse of 1,000,000 sec. This engine unequivocally can create a new era of space exploration that changes the way spacecraft operate. Today's space Explorers could travel in Cruise Liner fashion using the technology not considered by Aerospace America, the novel Dusty Plasma Fission Fragment Rocket Engine (FFRE). This NIAC study addresses the FFRE as well as its impact on Exploration Spacecraft design and operation. It uses common physics of the relativistic speed of fission fragments to produce thrust. It radiatively cools the fissioning dusty core and magnetically controls the fragments direction to practically implement previously patented, but unworkable designs. The spacecraft hosting this engine is no more complex nor more massive than the International Space Station (ISS) and would employ the successful ISS technology for assembly and check-out. The elements can be lifted in "chunks" by a Heavy Lift Launcher. This Exploration Spacecraft would require the resupply of small amounts of nuclear fuel for each journey and would be an in-space asset for decades just as any Cruise Liner on Earth. This study has synthesized versions of the FFRE, integrated one concept onto a host spacecraft designed for manned travel to Jupiter's moon, Callisto, and assessed that round trip journey. This engine, although unoptimized, produced 10 pounds force of thrust at a delivered specific impulse of 527,000 seconds for the entire 15-year mission while providing enormous amounts of electrical power to the spacecraft. A payload of 60 metric tons, included in the 300 metric ton vehicle, was carried to Callisto and back; the propellant tanks holding the 4 metric tons of fuel were not jettisoned in the process. The study concluded that the engine and spacecraft are within today's technology, could be built, tested, launched on several SLS (Space Launch System) (or similar) launchers, integrated, checked out, moved to an in-space base such as at a Lagrange point and operated for decades.

Manager or leader? Capitalize on the best of both!

Roberts, Cynthia

2005-05-31

As today's managers are faced with an ever increasing number of challenges, no one can argue that, now more than ever, good management skills are crucial for organizational success. Several researchers also suggest that managers in today's workplace cannot be successful without developing leadership skills as well. But what is the difference between management and leadership? Aren't they really the same thing? This article explores the differences and proposes the idea of managerial leadership, which blends both viewpoints. It also suggests a strategy that laboratory professionals can use to develop managerial leadership competency.

Physical inactivity is responsible for around 10% of all deaths and physical inactivity costs global healthcare systems billions of dollars each year. Here, we describe the human and economic costs of cardiovascular disease. Then, we explain that physical inactivity is a major modifiable risk factor for cardiovascular disease. The evidence of the role of physical activity in the primary prevention of cardiovascular disease is reviewed and we make the case that exercise is medicine.

Climate-induced forest dieback: An escalating global phenomenon?

USGS Publications Warehouse

Allen, Craig D.

2009-01-01

Forests, which today cover 30 percent of the world’s land surface (FAO, 2006), are being rapidly and directly transformed in many areas by the impacts of expanding human populations and economies. Less evident are the pervasive effects of ongoing climatic changes on the condition and status of forests around the world. Recent examples of drought and heat-related forest stress and dieback (defined here as tree mortality noticeably above usual mortality levels) are being documented from all forested continents, making it possible to begin to see global patterns. This article introduces these patterns and considers the possibility that many forests and woodlands today are at increasing risk of climate-induced dieback. A more comprehensive article (Allen et al., 2009) addresses this topic in considerably greater detail. While climate events can damage forests in many ways ranging from ice storms to tornadoes and hurricanes, the emphasis here is on climatic water stress, driven by drought and warm temperatures.

The Nazi Physicians as Leaders in Eugenics and "Euthanasia": Lessons for Today.

PubMed

Grodin, Michael A; Miller, Erin L; Kelly, Johnathan I

2018-01-01

This article, in commemoration of the 70th anniversary of the Doctors' Trial at Nuremberg, reflects on the Nazi eugenics and "euthanasia" programs and their relevance for today. The Nazi doctors used eugenic ideals to justify sterilizations, child and adult "euthanasia," and, ultimately, genocide. Contemporary euthanasia has experienced a progression from voluntary to nonvoluntary and from passive to active killing. Modern eugenics has included both positive and negative selective activities. The 70th anniversary of the Doctors' Trial at Nuremberg provides an important opportunity to reflect on the implications of the Nazi eugenics and "euthanasia" programs for contemporary health law, bioethics, and human rights. In this article, we will examine the role that health practitioners played in the promotion and implementation of State-sponsored eugenics and "euthanasia" in Nazi Germany, followed by an exploration of contemporary parallels and debates in modern bioethics. 1 .

Workplace etiquette for the medical practice employee.

PubMed

Hills, Laura

2010-01-01

Medical practice workplace etiquette is slowly being modified and fine-tuned. New workplace etiquette rules have become necessary because of advances in communications technology, shifting norms, and expectations of what constitutes good manners. Today's medical practice employees must concern themselves with traditional workplace manners but also the manners that come into play when they make or receive cell phone calls, text messages, and e-mails, and when they use social networking media outside of work. This article offers 25 rules for good manners in the medical practice that relate to the ways employees interact with people today, whether face-to-face or when using electronic communications technologies. It offers practical guidelines for making introductions both inside and outside the medical practice. This article also provides a self-quiz to help medical practice employees assess their workplace etiquette intelligence and 12 tips for good workplace table manners.

Today's experimentation in high energy physics is characterized by an increasing need for sensitivity to rare phenomena and complex physics signatures, which require the use of huge and sophisticated detectors and consequently a high performance readout and data acquisition. Multi-level triggering, hierarchical data collection and an always increasing amount of processing power, distributed throughout the data acquisition layers, will impose a number of features on the software environment, especially the need for a high level of standardization. Real-time UNIX seems, today, the best solution for the platform independence, operating system interface standards and real-time features necessary for data acquisition in HEP experiments. We present the results of the evaluation, in a realistic application environment, of a Real-Time UNIX operating system: the EP/LX real-time UNIX system.

Courage and today's nurse leader.

Clancy, Thomas R

2003-01-01

The virtue of courage is often overlooked in distinguishing successful leaders. This void is a reflection of the difficulty in defining just what courage is. Is courage facing risk without fear or overcoming fear to face risk? What are the differences between physical and moral courage? Can leaders develop courage? These and many other questions surround the nature of courage and how it pertains to leadership. It is the author's intent that readers have a general understanding of how courage affects nursing leadership in today's health care environment.

Physical demands in working life and individual physical capacity.

PubMed

Karlqvist, L; Leijon, O; Härenstam, A

2003-08-01

The purpose of this study was to investigate the prevalence of the excess of metabolic level (metabolic demands in work exceeding one-third of the individual's aerobic capacity) of working men and women today and to describe the population whose metabolic level is exceeded. A second aim was to explore how externally assessed metabolic demands match with the physical function and capacity of working men and women in jobs with the lowest and the highest demands. The aerobic power of each individual (94 men and 94 women) was estimated from heart rate and workload in sub-maximal tests from dynamic legwork on a cycle ergometer. Physical activity was assessed using a task-oriented interview technique. Physical function was measured by tests of muscle endurance in arms, abdomen and legs, handgrip pressure, balance and coordination. The calculation of individual metabolic demands during a "typical working day" showed that 27% of the men and 22% of the women exceeded their metabolic level. The results indicate that the physical fitness is low or somewhat low for two-thirds of the 94 men and for more than one-half of the 94 women. Women in the group with the highest job demands had significantly lower muscle endurance in the abdomen and legs and worse coordination than women in the group with the lowest job demands. Metabolic demands in working life today remain high. This is reflected in a mismatch between individual physical capacity and the physical demands of work for 25% of the population.

High-Efficiency, Multijunction Solar Cells for Large-Scale Solar Electricity Generation

NASA Astrophysics Data System (ADS)

Kurtz, Sarah

2006-03-01

A solar cell with an infinite number of materials (matched to the solar spectrum) has a theoretical efficiency limit of 68%. If sunlight is concentrated, this limit increases to about 87%. These theoretical limits are calculated using basic physics and are independent of the details of the materials. In practice, the challenge of achieving high efficiency depends on identifying materials that can effectively use the solar spectrum. Impressive progress has been made with the current efficiency record being 39%. Today's solar market is also showing impressive progress, but is still hindered by high prices. One strategy for reducing cost is to use lenses or mirrors to focus the light on small solar cells. In this case, the system cost is dominated by the cost of the relatively inexpensive optics. The value of the optics increases with the efficiency of the solar cell. Thus, a concentrator system made with 35%- 40%-efficient solar cells is expected to deliver 50% more power at a similar cost when compare with a system using 25%-efficient cells. Today's markets are showing an opportunity for large concentrator systems that didn't exist 5-10 years ago. Efficiencies may soon pass 40% and ultimately may reach 50%, providing a pathway to improved performance and decreased cost. Many companies are currently investigating this technology for large-scale electricity generation. The presentation will cover the basic physics and more practical considerations to achieving high efficiency as well as describing the current status of the concentrator industry.

Indirect detection of dark matter with γ rays.

PubMed

Funk, Stefan

2015-10-06

The details of what constitutes the majority of the mass that makes up dark matter in the Universe remains one of the prime puzzles of cosmology and particle physics today-80 y after the first observational indications. Today, it is widely accepted that dark matter exists and that it is very likely composed of elementary particles, which are weakly interacting and massive [weakly interacting massive particles (WIMPs)]. As important as dark matter is in our understanding of cosmology, the detection of these particles has thus far been elusive. Their primary properties such as mass and interaction cross sections are still unknown. Indirect detection searches for the products of WIMP annihilation or decay. This is generally done through observations of γ-ray photons or cosmic rays. Instruments such as the Fermi large-area telescope, high-energy stereoscopic system, major atmospheric gamma-ray imaging Cherenkov, and very energetic radiation imaging telescope array, combined with the future Cherenkov telescope array, will provide important complementarity to other search techniques. Given the expected sensitivities of all search techniques, we are at a stage where the WIMP scenario is facing stringent tests, and it can be expected that WIMPs will be either be detected or the scenario will be so severely constrained that it will have to be rethought. In this sense, we are on the threshold of discovery. In this article, I will give a general overview of the current status and future expectations for indirect searches of dark matter (WIMP) particles.

Bender, Carl M; DeKieviet, Maarten; Klevansky, S. P.

2013-01-01

-symmetric quantum mechanics (PTQM) has become a hot area of research and investigation. Since its beginnings in 1998, there have been over 1000 published papers and more than 15 international conferences entirely devoted to this research topic. Originally, PTQM was studied at a highly mathematical level and the techniques of complex variables, asymptotics, differential equations and perturbation theory were used to understand the subtleties associated with the analytic continuation of eigenvalue problems. However, as experiments on -symmetric physical systems have been performed, a simple and beautiful physical picture has emerged, and a -symmetric system can be understood as one that has a balanced loss and gain. Furthermore, the phase transition can now be understood intuitively without resorting to sophisticated mathe- matics. Research on PTQM is following two different paths: at a fundamental level, physicists are attempting to understand the underlying mathematical structure of these theories with the long-range objective of applying the techniques of PTQM to understanding some of the outstanding problems in physics today, such as the nature of the Higgs particle, the properties of dark matter, the matter–antimatter asymmetry in the universe, neutrino oscillations and the cosmological constant; at an applied level, new kinds of -synthetic materials are being developed, and the phase transition is being observed in many physical contexts, such as lasers, optical wave guides, microwave cavities, superconducting wires and electronic circuits. The purpose of this Theme Issue is to acquaint the reader with the latest developments in PTQM. The articles in this volume are written in the style of mini-reviews and address diverse areas of the emerging and exciting new area of -symmetric quantum mechanics. PMID:23509390

Gasenzer, E R; Leischik, R

2018-02-01

Music, with its various elements, such as rhythm, sound and melody had the unique ability even in prehistoric, ancient and medieval times to have a special fascination for humans. Nowadays, it is impossible to eliminate music from our daily lives. We are accompanied by music in shopping arcades, on the radio, during sport or leisure time activities and in wellness therapy. Ritualized drumming was used in the medical sense to drive away evil spirits or to undergo holy enlightenment. Today we experience the varied effects of music on all sensory organs and we utilize its impact on cardiovascular and neurological rehabilitation, during invasive cardiovascular procedures or during physical activities, such as training or work. The results of recent studies showed positive effects of music on heart rate and in therapeutic treatment (e. g. music therapy). This article pursues the impact of music on the body and the heart and takes sports medical aspects from the past and the present into consideration; however, not all forms of music and not all types of musical activity are equally suitable and are dependent on the type of intervention, the sports activity or form of movement and also on the underlying disease. This article discusses the influence of music on the body, pulse, on the heart and soul in the past and the present day.

Global warming and obesity: a systematic review.

PubMed

An, R; Ji, M; Zhang, S

2018-02-01

Global warming and the obesity epidemic are two unprecedented challenges mankind faces today. A literature search was conducted in the PubMed, Web of Science, EBSCO and Scopus for articles published until July 2017 that reported findings on the relationship between global warming and the obesity epidemic. Fifty studies were identified. Topic-wise, articles were classified into four relationships - global warming and the obesity epidemic are correlated because of common drivers (n = 21); global warming influences the obesity epidemic (n = 13); the obesity epidemic influences global warming (n = 13); and global warming and the obesity epidemic influence each other (n = 3). We constructed a conceptual model linking global warming and the obesity epidemic - the fossil fuel economy, population growth and industrialization impact land use and urbanization, motorized transportation and agricultural productivity and consequently influences global warming by excess greenhouse gas emission and the obesity epidemic by nutrition transition and physical inactivity; global warming also directly impacts obesity by food supply/price shock and adaptive thermogenesis, and the obesity epidemic impacts global warming by the elevated energy consumption. Policies that endorse deployment of clean and sustainable energy sources, and urban designs that promote active lifestyles, are likely to alleviate the societal burden of global warming and obesity. © 2017 World Obesity Federation.

Weight maintenance: challenges, tools and strategies for primary care physicians[Link

PubMed Central

Soleymani, T.; Daniel, S.

2015-01-01

Summary Obesity is recognized as a chronic disease and one of the major healthcare challenges facing us today. Weight loss can be achieved via lifestyle, pharmacological and surgical interventions, but weight maintenance remains a lifetime challenge for individuals with obesity. Guidelines for the management of obesity have highlighted the role of primary care providers (PCPs). This review examines the long‐term outcomes of clinical trials to identify effective weight maintenance strategies that can be utilized by PCPs. Because of the broad nature of the topic, a structured PubMed search was conducted to identify relevant research articles, peer‐reviewed reviews, guidelines and articles published by regulatory bodies. Trials have demonstrated the benefit of sustained weight loss in managing obesity and its comorbidities. Maintaining 5–10% weight loss for ≥1 year is known to ameliorate many comorbidities. Weight maintenance with lifestyle modification – although challenging – is possible but requires long‐term support to reinforce diet, physical activity and behavioural changes. The addition of pharmacotherapy to lifestyle interventions promotes greater and more sustained weight loss. Clinical evidence and recently approved pharmacotherapy has given PCPs improved strategies to support their patients with maintenance of weight loss. Further studies are needed to assess the translation of these strategies into clinical practice. PMID:26490059

This article examines the relationship between philosophy and culture in global bioethics. First, it studies what is meant by the term "global" in global bioethics. Second, the author introduces four different types, or recognizable trends, in philosophical inquiry in bioethics today. The main argument is that, in order to make better sense of the complexity of the ethical questions and challenges we face today across the globe, we need to embrace the universal nature of self-critical and analytical philosophical analysis and argumentation, rather than using seemingly philosophical approaches to give unjustified normative emphasis on different cultural approaches to bioethics.

Eley, B M

1997-04-12

This is the first article in a series of seven on the future of dental amalgam. Dental amalgam is still the most useful restorative material for posterior teeth and has been used successfully for over 100 years. The history of dental amalgam since its introduction in 1819 and the controversies about its use between 1834 and today are described. The composition of the various dental amalgams in clinical use today are then reported. It finally covers the corrosion of amalgams since this is the means by which metals, including mercury, can be released.

Scratching the Surface of Martian Habitability

Conrad, Pamela G.

2014-01-01

Earth and Mars, though formed at the same time from the same materials, look very different today. Early in their histories they evolved through some of the same processes, but at some point their evolutionary paths diverged, sending them in perhaps irrevocably different directions. Knowledge of the factors that contributed to such different outcomes will help to determine how planets become habitable and how common habitable planets may be. The Mars surface environment is harsh today, but in situ measurements of ancient sedimentary rock by Mars Science Laboratory reveal chemical and mineralogical evidence of past conditions that might have been more favorable for life to exist. But chemistry is only part of what is required to make an environment habitable. Physical conditions constrain the chemical reactions that underlie life processes; the chemical and physical characteristics that make planets habitable are thus entangled.

Hydroxylated Polychlorinated Biphenyls in the Environment: Sources, Fate, and Toxicities

Tehrani, Rouzbeh; Van Aken, Benoit

2013-01-01

Hydroxylated polychlorinated biphenyls (OH-PCBs) are produced in the environment by the oxidation of PCBs through a variety of mechanisms, including metabolic transformation in living organisms and abiotic reactions with hydroxyl radicals. As a consequence, OH-PCBs have been detected in a wide range of environmental samples, including animal tissues, water, and sediments. OH-PCBs have recently raised serious environmental concerns because they exert a variety of toxic effects at lower doses than the parent PCBs and they are disruptors of the endocrine system. Although evidence has accumulated about the widespread dispersion of OH-PCBs in various compartments of the ecosystem, little is currently known about their biodegradation and behavior in the environment. OH-PCBs are today increasingly considered as a new class of environmental contaminants that possess specific chemical, physical, and biological properties not shared with the parent PCBs. This article reviews recent findings regarding the sources, fate, and toxicities of OH-PCBs in the environment. PMID:23636595

One of the trends in construction material science is development and implementation of highly effective finish materials which improve architectural exterior of cities. Silicate materials widely-used in the construction today have rather low decorative properties. Different coloring agents are used in order to produce competitive materials, but due to the peculiarities of the production, process very strict specifications are applied to them. The use of industrial wastes or variety of rock materials as coloring agents is of great interest nowadays. The article shows that clay rock can be used as raw material in production of finish materials of non-autoclaved solidification. This raw material due to its material composition actively interacts with cementing component in steam treatment at 90–95 °C with formation of cementing joints that form a firm coagulative-cristalized and crystallization structure of material providing high physic-mechanical properties of silicate goods. It is determined that energy-saving, colored finish materials with compression strength up to 16 MPa can be produced from clay rocks.

[The history of optical signals for traffic regulation].

PubMed

Draeger, J; Harsch, V

2008-04-01

For signal transmission in traffic today, different optical, acoustic, or other physical or technical means are used for information. The different kinds of traffic (water navigation, road and rail, and, later air transport) made traffic regulation necessary early on. This regulation, from its very beginning in ancient times, began by means of optical signals; nowadays, this remains the most important method. From the very start, minimum requirements for the navigator's vision, color discrimination, dark adaptation, and even visual field were needed. For historical reasons, it was in seafaring medicine that these first developed. Besides the development of the different signals, methods for checking the requirements were soon developed. National and international requirements have been very different. Only within the last 50 years has international cooperation led to the acceptance of general standards for the different traffic modes. This article discusses the technical development of optical signals for the different kinds of traffic, from ancient times to the present, and explains the development of minimum requirements for the different visual functions.

Osteoarthritis (OA) is prevalent in today's population, including the athletic and recreationally active "middle-aged" population. OA is a degenerative condition of the articular/hyaline cartilage of synovial joints and commonly affects the knee joint. In general, athletic participation does not specifically influence a higher incidence of knee OA in this population; however, traumatic injury to the knee joint poses a definitive risk in developing early-onset OA. The purpose of this article is to review evidence-based nonpharmacological interventions for the conservative management of knee OA. Manual therapy, therapeutic exercise, patient education, and weight management are strongly supported in the literature for conservative treatment of knee OA. Modalities [thermal, electrical stimulation (ES), and low-level laser therapy (LLLT)] and orthotic intervention are moderately supported in the literature as indicated management strategies for knee OA. While many strongly supported conservative interventions have been published, additional research is needed to determine the most effective approach in treating knee OA.

Children and war: current understandings and future directions.

PubMed

Berman, H

2001-01-01

During the last decade, the number of children whose lives have been disrupted by war, oppression, terror, and other forms of conflict has grown tremendously. When the United Nations High Commission for Refugees was first established during the 1950s to provide international protection to refugees following World War II, it was estimated that there were 1.5 million refugees and displaced persons. Today there are approximately 14 million, about three-fourths of whom are women and children. Although the experiences of refugee children and adolescents vary considerably, many have witnessed or experienced the death or murder of loved ones. Upon resettlement, they face numerous challenges. Research with this population is a relatively new area of investigation, but there is evidence that many of these young people experience long-term physical and emotional health problems. In this article, current research findings are reviewed, the widespread emphasis in the literature on post-traumatic stress disorder (PTSD) is critically examined, future research directions are suggested, and implications for public health nurses are addressed.

Using Smartphones to Collect Behavioral Data in Psychological Science: Opportunities, Practical Considerations, and Challenges.

2016-11-01

Smartphones now offer the promise of collecting behavioral data unobtrusively, in situ, as it unfolds in the course of daily life. Data can be collected from the onboard sensors and other phone logs embedded in today's off-the-shelf smartphone devices. These data permit fine-grained, continuous collection of people's social interactions (e.g., speaking rates in conversation, size of social groups, calls, and text messages), daily activities (e.g., physical activity and sleep), and mobility patterns (e.g., frequency and duration of time spent at various locations). In this article, we have drawn on the lessons from the first wave of smartphone-sensing research to highlight areas of opportunity for psychological research, present practical considerations for designing smartphone studies, and discuss the ongoing methodological and ethical challenges associated with research in this domain. It is our hope that these practical guidelines will facilitate the use of smartphones as a behavioral observation tool in psychological science. © The Author(s) 2016.

‘It’s All Done With Mirrors’: V.S. Ramachandran and the Material Culture of Phantom Limb Research

PubMed Central

Guenther, Katja

2016-01-01

This article examines the material culture of neuroscientist Vilayanur S. Ramachandran’s research into phantom limbs. In the 1990s Ramachandran used a ‘mirror box’ to ‘resurrect’ phantom limbs and thus to treat the pain that often accompanied them. The experimental success of his mirror therapy led Ramachandran to see mirrors as a useful model of brain function, a tendency that explains his attraction to work on ‘mirror neurons’. I argue that Ramachandran’s fascination with and repeated appeal to the mirror can be explained by the way it allowed him to confront a perennial problem in the mind and brain sciences, that of the relationship between a supposedly immaterial mind and a material brain. By producing what Ramachandran called a ‘virtual reality’, relating in varied and complex ways to the material world, the mirror reproduced a form of psycho-physical parallelism and dualistic ontology, while conforming to the materialist norms of neuroscience today.

Limits on the maximum attainable efficiency for solid-state lighting

NASA Astrophysics Data System (ADS)

Coltrin, Michael E.; Tsao, Jeffrey Y.; Ohno, Yoshi

2008-03-01

Artificial lighting for general illumination purposes accounts for over 8% of global primary energy consumption. However, the traditional lighting technologies in use today, i.e., incandescent, fluorescent, and high-intensity discharge lamps, are not very efficient, with less than about 25% of the input power being converted to useful light. Solid-state lighting is a rapidly evolving, emerging technology whose efficiency of conversion of electricity to visible white light is likely to approach 50% within the next years. This efficiency is significantly higher than that of traditional lighting technologies, with the potential to enable a marked reduction in the rate of world energy consumption. There is no fundamental physical reason why efficiencies well beyond 50% could not be achieved, which could enable even greater world energy savings. The maximum achievable luminous efficacy for a solid-state lighting source depends on many different physical parameters, for example the color rendering quality that is required, the architecture employed to produce the component light colors that are mixed to produce white, and the efficiency of light sources producing each color component. In this article, we discuss in some detail several approaches to solid-state lighting and the maximum luminous efficacy that could be attained, given various constraints such as those listed above.

An Introduction to Tensors for Students of Physics and Engineering

NASA Technical Reports Server (NTRS)

Kolecki, Joseph C.

2002-01-01

Tensor analysis is the type of subject that can make even the best of students shudder. My own post-graduate instructor in the subject took away much of the fear by speaking of an implicit rhythm in the peculiar notation traditionally used, and helped us to see how this rhythm plays its way throughout the various formalisms. Prior to taking that class, I had spent many years "playing" on my own with tensors. I found the going to be tremendously difficult but was able, over time, to back out some physical and geometrical considerations that helped to make the subject a little more transparent. Today, it is sometimes hard not to think in terms of tensors and their associated concepts. This article, prompted and greatly enhanced by Marlos Jacob, whom I've met only by e-mail, is an attempt to record those early notions concerning tensors. It is intended to serve as a bridge from the point where most undergraduate students "leave off" in their studies of mathematics to the place where most texts on tensor analysis begin. A basic knowledge of vectors, matrices, and physics is assumed. A semi-intuitive approach to those notions underlying tensor analysis is given via scalars, vectors, dyads, triads, and higher vector products. The reader must be prepared to do some mathematics and to think. For those students who wish to go beyond this humble start, I can only recommend my professor's wisdom: find the rhythm in the mathematics and you will fare pretty well.

Children as codesigners of new technologies: valuing the imagination to transform what is possible.

PubMed

Druin, Allison

2010-01-01

The technological complexity and richness of a child's environment today is far beyond what any adults today experienced when they were growing up. For example, no adult today knows what it is like to be a four-year-old using his or her first iPhone app or Webkinz account. Therefore, we seek ways to understand what children need in today's new technologies even without ourselves being children. Since 1999, young people ages seven to eleven have been the author's partners in codesigning new educational technologies at the University of Maryland's Human-Computer Interaction Lab. This work has helped inform who children are--what matters to them, what technologies need to be changed, and what needs to be built for the future. This work uses cooperative inquiry, a set of codesign methods that can enable adults and children to share their ideas while minimizing the differences in age and communication styles. This article describes low-tech methods for brainstorming, offering feedback, and supporting creative change in technology prototype designs. Examples of technologies are discussed and insights from children shared.

Einstein, Bohr, and Bell

NASA Astrophysics Data System (ADS)

Bellac, Michel Le

2014-11-01

The final form of quantum physics, in the particular case of wave mechanics, was established in the years 1925-1927 by Heisenberg, Schrödinger, Born and others, but the synthesis was the work of Bohr who gave an epistemological interpretation of all the technicalities built up over those years; this interpretation will be examined briefly in Chapter 10. Although Einstein acknowledged the success of quantum mechanics in atomic, molecular and solid state physics, he disagreed deeply with Bohr's interpretation. For many years, he tried to find flaws in the formulation of quantum theory as it had been more or less accepted by a large majority of physicists, but his objections were brushed away by Bohr. However, in an article published in 1935 with Podolsky and Rosen, universally known under the acronym EPR, Einstein thought he had identified a difficulty in the by then standard interpretation. Bohr's obscure, and in part beyond the point, answer showed that Einstein had hit a sensitive target. Nevertheless, until 1964, the so-called Bohr-Einstein debate stayed uniquely on a philosophical level, and it was actually forgotten by most physicists, as the few of them aware of it thought it had no practical implication. In 1964, the Northern Irish physicist John Bell realized that the assumptions contained in the EPR article could be tested experimentally. These assumptions led to inequalities, the Bell inequalities, which were in contradiction with quantum mechanical predictions: as we shall see later on, it is extremely likely that the assumptions of the EPR article are not consistent with experiment, which, on the contrary, vindicates the predictions of quantum physics. In Section 3.2, the origin of Bell's inequalities will be explained with an intuitive example, then they will be compared with the predictions of quantum theory in Section 3.3, and finally their experimental status will be reviewed in Section 3.4. The debate between Bohr and Einstein goes much beyond a simple controversy, which is after all almost eighty years old and has been settled today. In fact, the concept introduced in this debate, that of entanglement, lies at the heart of many very important developments of modern quantum physics, in particular all those linked to quantum information (Chapter 8). Moreover, we shall see that the phenomenon of non-local correlations compels us to revise in depth our space-time representation of quantum processes. These are the two reasons why a whole chapter is devoted to this debate.

Piper, Llewellyn E

2008-01-01

The new generation of workforce entering health care today is the new challenge for leadership. This young workforce, known as the "Generation-Y," is demanding a different organizational culture to meet its needs. These new spoilers, once the babies of the baby boomers, will once again test the creativity and patience of their parents, who are now the leaders in health care. The baby boomer leaders of today face a delicate balance to meet the new demands of the Generation-Y workforce, along with the patients' demands. At stake in this balance is the viability of health care as we know it today. If the leadership of health care fails to grab hold of this new generation of employees, the ability to provide safe and quality health care and the survivability of the organization will be compromised. This article identifies the problem and provides guidelines to journey through this new wave of spoilers.

Today's health care organizations face tremendous challenges and fierce competition. These pressures impact the decisions that managers must execute on any given day, not to mention the ever-present constraints of time, personnel, competencies, and finances. The importance of making quality and informed decisions cannot be underestimated. Traditional decision making methods are inadequate for today's larger, more complex health care organizations and the rapidly changing health care environment. As a result, today's health care managers and their teams need new approaches to making decisions for their organizations. This article examines the managerial decision making process and offers a model that can be used as a decision making template to help managers successfully navigate the choppy health care seas. The administrative decision making model will enable health care managers and other key decision makers to avoid the common pitfalls of poor decision making and guide their organizations to success.

2016-06-01

The aim of this study was to review the evidence to date on the association between physical activity and safety from crime. Articles with adult populations of 500+ participants investigating the association between physical activity and safety from crime were included. A methodological quality assessment was conducted using an adapted version of the Downs and Black checklist. The literature search identified 15,864 articles. After assessment of titles, abstracts and full-texts, 89 articles were included. Most articles (84.3%) were derived from high-income countries and only 3 prospective articles were identified. Articles presented high methodological quality. In 38 articles (42.7%), at least one statistically significant association in the expected direction was reported (ie, safety from crime was positively associated with physical activity). Nine articles (10.1%) found an association in the unexpected direction and 42 (47.2%) did not find statistically significant associations. The results did not change when we analyzed articles separately by sex, age, type of measurement, or domains of physical activity evaluated. The current evidence, mostly based on cross-sectional studies, suggests a lack of association between physical activity and safety from crime. Prospective studies and natural experiments are needed, particularly in areas with wide crime variability.

History of Psychology Publish and Perish: Psychology's Most Prolific Authors Are Not Always the Ones We Remember.

PubMed

Green, Christopher D

2017-01-01

What is the relationship between being highly prolific in the realm of publication and being remembered as a great psychologist of the past? In this study, the PsycINFO database was used to identify the historical figures who wrote the most journal articles during the half-century from 1890 to 1939. Although a number of the 10 most prolific authors are widely remembered for their influence on the discipline today-E. L. Thorndike, Karl Pearson, E. B. Titchener, Henri Pi6ron-the majority are mostly forgotten. The data were also separated into the 5 distinct decades. Once again, a mixture of eminent and obscure individuals made appearances. Most striking, perhaps, was the great increase in articles published over the course of the half-century-approximately doubling each decade-and the enormous turnover in who was most prolific, decade over decade. In total, 100 distinct individuals appeared across just 5 lists of about 25 names each.

Teaching Einsteinian physics at schools: part 3, review of research outcomes

NASA Astrophysics Data System (ADS)

Kaur, Tejinder; Blair, David; Moschilla, John; Stannard, Warren; Zadnik, Marjan

2017-11-01

This paper reviews research results obtained from Einsteinian physics programs run by different instructors with Years 6, 9, 10 and 11 students using the models and analogies described in parts 1 and 2. The research aimed to determine whether it is possible to teach Einsteinian physics and to measure the changes in student attitudes to physics engendered by introducing the modern concepts that underpin technology today. Results showed that students easily coped with the concepts of Einsteinian physics, and considered that they were not too young for the material presented. Importantly, in all groups, girls improved their attitude to physics considerably more than the boys, generally achieving near parity with the boys.

What is behind small deviations of quantum mechanics theory from experiments? Observer's mathematics point of view

NASA Astrophysics Data System (ADS)

Khots, Boris; Khots, Dmitriy

2014-12-01

Certain results that have been predicted by Quantum Mechanics (QM) theory are not always supported by experiments. This defines a deep crisis in contemporary physics and, in particular, quantum mechanics. We believe that, in fact, the mathematical apparatus employed within today's physics is a possible reason. In particular, we consider the concept of infinity that exists in today's mathematics as the root cause of this problem. We have created Observer's Mathematics that offers an alternative to contemporary mathematics. This paper is an attempt to relay how Observer's Mathematics may explain some of the contradictions in QM theory results. We consider the Hamiltonian Mechanics, Newton equation, Schrodinger equation, two slit interference, wave-particle duality for single photons, uncertainty principle, Dirac equations for free electron in a setting of arithmetic, algebra, and topology provided by Observer's Mathematics (see www.mathrelativity.com). Certain results and communications pertaining to solution of these problems are provided.

Touch during childbirth: yesterday and today.

PubMed

Klein, Michele

2003-02-01

Birth helpers touch the parturient woman in many ways. They make physical contact to diagnose difficulties and manipulate safe delivery. They may also touch the woman in non-physical ways, with special words, as they help a woman to give birth. Some hope also for a divine touch, as Jewish tradition teaches that God is a partner in the birth process. This paper takes a historical look at the different forms of touch used by birth attendants to ease the safe arrival of a healthy infant. We hope that this short retrospective will encourage today's birth helpers, especially doctors and midwives, to notice how they themselves touch birthing women. We hope to promote awareness of the verbal and non-verbal language of touch and to encourage the use of the art of touch among medical staff who are now more skilled than ever before in applying scientific touch to patients.

Nurses Urged to Prepare for Sex Education.

PubMed

2017-01-01

Editors' note: From its first issue in 1900 through to the present day, AJN has unparalleled archives detailing nurses' work and lives over more than a century. These articles not only chronicle nursing's growth as a profession within the context of the events of the day, but they also reveal prevailing societal attitudes about women, health care, and human rights. Today's nursing school curricula rarely include nursing's history, but it's a history worth knowing. To this end, From the AJN Archives highlights articles selected to fit today's topics and times.This month we reprint a brief "Professional Practice" note from the June 1969 issue about what was described as the first family planning conference for nurse educators. Speakers emphasized the need to make this subject a routine part of nursing school curricula (despite debates over the nurse's role in family planning), "so that nurses can counsel out of wisdom and not from piety or ignorance." Speakers included James Lieberman, MD, who years later coauthored with his daughter a teen sex guide, and Alan Guttmacher, MD, then president of Planned Parenthood, whose Center for Family Planning Program Development within that organization was later renamed the Guttmacher Institute in his honor.Nurses today are deeply involved in sexual and reproductive health care. In this issue, public health specialist Diane Santa Maria and colleagues offer ways to advance sexual and reproductive health care for adolescents by devising more friendly, youth-oriented clinical settings.

Towards quantifying dynamic human-human physical interactions for robot assisted stroke therapy.

PubMed

Mohan, Mayumi; Mendonca, Rochelle; Johnson, Michelle J

2017-07-01

Human-Robot Interaction is a prominent field of robotics today. Knowledge of human-human physical interaction can prove vital in creating dynamic physical interactions between human and robots. Most of the current work in studying this interaction has been from a haptic perspective. Through this paper, we present metrics that can be used to identify if a physical interaction occurred between two people using kinematics. We present a simple Activity of Daily Living (ADL) task which involves a simple interaction. We show that we can use these metrics to successfully identify interactions.

Children's supernatural thinking as a signalling behaviour in early childhood.

PubMed

Hernández Blasi, Carlos; Bjorklund, David F; Ruiz Soler, Marcos

2017-08-01

In this study, we analysed the reaction times of 137 college students when making decisions on pairs of hypothetical children verbalizing different types of vignettes and/or exhibiting different physical appearance (photographs of faces). Vignettes depicted immature and mature versions of both supernatural (e.g., 'The sun's not out today because it's mad' vs. 'The sun's not out today because the clouds are blocking it') and natural ('I can remember all 20 cards!' vs. 'I can remember 6 or 7 cards') explanations to ordinary phenomena. Photographs of children's faces were morphed with a physical appearance of approximately 4-7 years old or approximately 8-10 years old. In earlier research, immature supernatural thinking produced positive-affect reactions from adults and older adolescents (14-18 years old) towards young children, with cognitive cues being more important than physical-appearance cues in influencing adults' judgements. Reaction times to make decisions varied for the Supernatural and Natural vignettes and for the immature and mature vignettes/faces, reflecting the differential cognitive effort adults used for making decisions about aspects of children's physical appearance and verbal expressions. The findings were interpreted in terms of the critical role that young children's immature supernatural thinking has on adults' perception, analogous to the evolved role of immature physical features on adults' perception of infants. © 2016 The British Psychological Society.

Price, Anna E; Corwin, Sara J; Friedman, Daniela B; Laditka, Sarah B; Colabianchi, Natalie; Montgomery, Kara M

2011-04-01

Physical activity may promote cognitive health in older adults. Popular media play an important role in preventive health communication. This study examined articles discussing associations between physical activity and cognitive health in top-circulating magazines targeting older adults. 42,753 pages of magazines published from 2006 to 2008 were reviewed; 26 articles met inclusion criteria. Explanations regarding the link between physical activity and cognitive health were provided in 57.7% of articles. These explanations were generally consistent with empirical evidence; however, few articles included empirical evidence. Physical activity recommendations were presented in 80.8% of articles; a wide range was recommended (90-300 min of physical activity per wk). Socioeconomic status and education level were not mentioned in the text. Results suggest an opportunity for greater coverage regarding the role of physical activity in promoting cognitive health in popular media. Magazine content would benefit from including more empirical evidence, culturally sensitive content, and physical activity recommendations that are consistent with U.S. guidelines.

Applications of Intelligent Technology to Power System Supervisory Control and Protection Systems

Power system supervisory control and protection systems provide utilities with capabilities that are key to a planning business function, i.e., delivering power in a reliable and safe manner. A quality system solution is central to effective operation of a utility's most critical and costly generation, transmission, and distribution assets. The challenging issues for these systems today are not the same as they were few years ago. Today, there is much more placed on integration, use of new IT technologies, and access to information for more purposes. This article presents the topics of intelligent technology to the power system supervisory control and protection systems.

PT quantum mechanics.

PubMed

Bender, Carl M; DeKieviet, Maarten; Klevansky, S P

2013-04-28

PT-symmetric quantum mechanics (PTQM) has become a hot area of research and investigation. Since its beginnings in 1998, there have been over 1000 published papers and more than 15 international conferences entirely devoted to this research topic. Originally, PTQM was studied at a highly mathematical level and the techniques of complex variables, asymptotics, differential equations and perturbation theory were used to understand the subtleties associated with the analytic continuation of eigenvalue problems. However, as experiments on PT-symmetric physical systems have been performed, a simple and beautiful physical picture has emerged, and a PT-symmetric system can be understood as one that has a balanced loss and gain. Furthermore, the PT phase transition can now be understood intuitively without resorting to sophisticated mathematics. Research on PTQM is following two different paths: at a fundamental level, physicists are attempting to understand the underlying mathematical structure of these theories with the long-range objective of applying the techniques of PTQM to understanding some of the outstanding problems in physics today, such as the nature of the Higgs particle, the properties of dark matter, the matter-antimatter asymmetry in the universe, neutrino oscillations and the cosmological constant; at an applied level, new kinds of PT-synthetic materials are being developed, and the PT phase transition is being observed in many physical contexts, such as lasers, optical wave guides, microwave cavities, superconducting wires and electronic circuits. The purpose of this Theme Issue is to acquaint the reader with the latest developments in PTQM. The articles in this volume are written in the style of mini-reviews and address diverse areas of the emerging and exciting new area of PT-symmetric quantum mechanics.

A concept of integrated environmental approach for building upgrades and new construction: Part 1—setting the stage

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bomberg, Mark; Gibson, Michael; Zhang, Jian

This article highlights the need for an active role for building physics in the development of near-zero energy buildings while analyzing an example of an integrated system for the upgrade of existing buildings. The science called either Building Physics in Europe or Building Science in North America has so far a passive role in explaining observed failures in construction practice. In its new role, it would be integrating modeling and testing to provide predictive capability, so much needed in the development of near-zero energy buildings. The authors attempt to create a compact package, applicable to different climates with small modificationsmore » of some hygrothermal properties of materials. This universal solution is based on a systems approach that is routine for building physics but in contrast to separately conceived sub-systems that are typical for the design of buildings today. One knows that the building structure, energy efficiency, indoor environmental quality, and moisture management all need to be considered to ensure durability of materials and control cost of near-zero energy buildings. These factors must be addressed through contributions of the whole design team. The same approach must be used for the retrofit of buildings. As this integrated design paradigm resulted from demands of sustainable built environment approach, building physics must drop its passive role and improve two critical domains of analysis: (i) linked, real-time hygrothermal and energy models capable of predicting the performance of existing buildings after renovation and (ii) basic methods of indoor environment and moisture management when the exterior of the building cannot be modified.« less
