    Full Text Available The Sixth North American Caribou workshop was attended by over 200 people from across North America, as well as four special guests from Russia. Participants were very surprised to see and hear about caribou living in large cedar forests and on mountain-tops where snow depths exceeded several meters, and the only available forage was the lichens growing on trees. We believe that the workshop was a major success with many excellent presentations and posters, as well as opportunities for the participants to meet and discuss caribou research, ecology, and management with their counterparts from across North America. These proceedings include a wide range of excellent papers that provide a permanent record of the workshop. The editors thank the authors and reviewers for their efforts to produce and review these papers.

  12. Cubic nitrides of the sixth group of transition metals formed by nitrogen ion irradiation during metal condensation

    Nitrogen-containing phases of chromium, molybdenum and tungsten were formed by evaporation of the metal under simultaneous nitrogen ion irradiation. With gradually increasing ion irradiation intensity, chromium forms initially Cr and Cr{sub 2}N phase mixtures, then additionally CrN appears, and at the highest intensities pure CrN films are formed. Molybdenum also forms pure nitride MoN under intense ion bombardment. However, in this case two different crystal structures are found, the stable hexagonal phase and the metastable cubic high-temperature phase. The latter is favoured under intense ion irradiation. In the case of tungsten, even at the highest intensities, only phase mixtures of W and W{sub 2}N were formed. These observed differences can be explained by the low reactivity of these metals towards nitrogen and the low chemical stability of the nitrides, particularly of WN. The metastable high-temperature structure of MoN is formed under the particular conditions of ion bombardment with rapid energy dissipation. (orig.)

    The diagnosis of cerebral venous sinus thrombosis still remains a real challenge. Seizure, unusual headache with sudden onset, unexplained persistently unilateral vascular headache and neurologic deficit-which is difficult to be attributed to a vascular territory are some of the suggestive symptoms. An isolated sixth nerve palsy is discussed as a rare presentation for cerebral venous thrombosis. Following the extensive investigation to rule out other possible diagnoses, magnetic resonance venogram revealed the final etiology of sixth nerve palsy that was ipsilateral left transverse sinus thrombosis; therefore, anticoagulant treatment with low molecular weight heparin was administered. Rapid and accurate diagnosis and treatment cause to achieve excellent outcomes for most patients. Considering different clinical features, risk factors and high index of suspicion are helpful to reach the diagnosis. Copyright © 2016 Elsevier Inc. All rights reserved.

    This thesis is a qualitative study of the implications of the resit policy of A levels for student learning in sixth-form education in England. In contrast to many other high-stakes examinations which test students only at the end of a course, A levels use a modular format where students are allowed to resit past units within the two-year sixth-form course with no limit or penalty. Since resits were introduced extensively to A levels ten years ago, the A-level results have been improving stea...

  17. Sixth taste – starch taste?

    Directory of Open Access Journals (Sweden)

    Zygmunt Zdrojewicz

    2017-06-01

    Full Text Available Scientists from Oregon State University, USA, came up with the newest theory of the sixth taste – starch taste that might soon join the basic five tastes. This argument is supported by studies done on both animals and humans, the results of which seem to indicate the existence of separate receptors for starch taste, others than for sweet taste. Starch is a glucose homopolymer that forms an α-glucoside chain called glucosan or glucan. This polysaccharide constitutes the most important source of carbohydrates in food. It can be found in groats, potatoes, legumes, grains, manioc and corn. Apart from its presence in food, starch is also used in textile, pharmaceutical, cosmetic and stationery industries as well as in glue production. This polysaccharide is made of an unbranched helical structure – amylose (15–20%, and a structure that forms branched chains – amylopectin (80–85%. The starch structure, degree of its crystallisation or hydration as well as its availability determine the speed of food-contained starch hydrolysis by amylase. So far, starch has been considered tasteless, but the newest report shows that for people of different origins it is associated with various aliments specific for each culture. Apart from a number of scientific experiments using sweet taste inhibitors, the existence of the sixth taste is also confirmed by molecular studies. However, in order to officially include starch taste to the basic human tastes, it must fulfil certain criteria. The aim of the study is to present contemporary views on starch.

  10. Belgian Federalism after the Sixth State Reform

    2015-11-01

    Full Text Available This paper highlights the most important institutional evolutions of Belgian federalism stemming from the implementation of the sixth state reform (2012-2014. This reform inter alia included a transfer of powers worth 20 billion euros from the federal level to the level of the federated states, a profound reform of the Senate, and a substantial increase in fiscal autonomy for the regions. This contribution critically analyses the current state of Belgian federalism. Although the sixth state reform realized important and long-awaited changes, further evolutions are to be expected. Since the Belgian state model has reached its limits with regard to complexity and creativity, politicians and academics should begin to reflect on the seventh state reform with the aim of increasing the transparency of the current Belgian institutional labyrinth.

  14. The immune system as the sixth sense.

    Science.gov (United States)

    Blalock, J E

    2005-02-01

    One of the truly remarkable discoveries in modern biology is the finding that the nervous system and immune system use a common chemical language for intra- and inter-system communication. This review will discuss some of the pivotal results that deciphered this chemical language. Specifically the nervous and immune systems produce a common set of peptide and nonpeptide neurotransmitters and cytokines that act on a common repertoire of receptors in the two systems. The paper will also review more recent studies that have delineated hardwired and humoral pathways for such bidirectional communication. This is discussed in the context of the idea that the sharing of ligands and receptors allows the immune system to serve as the sixth sense that notifies the nervous system of the presence of entities, such as viruses and bacteria, that are imperceptible to the classic senses. Lastly, this review will suggest ways to apply the newfound knowledge of the sixth sense to understand a placebo effect and to treat human disease.

    The Sixth Annual Mouse Genome Conference was held in October, 1992 at Buffalo, USA. The mouse is one of the primary model organisms in the Human Genome Project. Through the use of gene targeting studies the mouse has become a powerful biological model for the study of gene function and, in addition, the comparison of the many homologous mutations identified in human and mouse have widened our understanding of the biology of these two organisms. A primary goal in the mouse genome program has been to create a genetic map of STSs of high resolution (<1cM) that would form the basis for the physical mapping of the whole mouse genome. Buffalo saw substantial new progress towards the goal of a very high density genetic map and the beginnings of substantive efforts towards physical mapping in chromosome regions with a high density of genetic markers.

    Herein, we report a patient who had an isolated sixth nerve palsy due to a petrous apex cholesterol granuloma. The sixth nerve palsy appeared acutely and then spontaneously resolved over several months, initially suggesting a microvascular origin of the palsy. Subsequent recurrences of the palsy indicated a different pathophysiologic etiology and MRI revealed the lesion at the petrous apex. Surgical resection improved the compressive effect of the lesion at Dorello’s canal and clinical improvement was observed. A relapsing–remitting sixth nerve palsy is an unusual presentation of this rare lesion. PMID:28261154

  3. SIXTH ERDA WORKSHOP ON PERSONNEL NEUTRON DOSIMETRY

    1977-07-11

    This workshop was the sixth of a series and was held on July 11 and 12, 1977, at the Oak Ridge National Laboratory in Oak Ridge, Tennessee. Those presenting papers at the Sixth Workshop prepared summary reports of their recent work for inclusion in this document. The reports are reproduced here as submitted by the participants, with only minor editing. This year's Workshop took a decidedly international flavor, with participants from seven countries in addition to the United States. The significance of this group's contributions has raised the possibility that the next Neutron Dosimetry Workshop may be held in Europe. Of particular interest at the Workshop was the keynote address by Dr. Harald Rossi. He commented that there is evidence that 1) accepted values of RBE for low absorbed doses of neutrons may be low by an order of magnitude or more and 2) the risk of leukemia is significant at 0.5 rad to the bone narrow. A reduction of the limit for permissible neutron exposure, which could result from consideration of this information, would necessitate major improvements in our "middle ages" neutron dosimetry. A number of participants reported conversions to thermoluminescent dosimeter (TLD) systems. This move has not been unanimous, however, as there were several reports of apparently satisfactory fission fragment, activation foil, and NTA film dosimeters. While thementionof NTA film resulted in the usual discussion of energy cut off and humidity effects, it seems the use of NTA in accelerator environments still has some merit. Discussion of fission fragment dosimeters centered around track etching techniques, which have shown some improvement. Of particular interest was Tommasino's report on the use of polycarbonate centrifuge tubes as the sensitive element. Thermally stimulated exoelectron emission (TSEE), never very popular for personnel dosimetry, has lost additional ground with the report that the neutron/gamma response ratio is much less than

    2006-03-01

    Full Text Available Since etching is completed at the same stage as priming and bonding, when applying the sixth and seventh generation bonding, the exposed smear layers are constantly surrounded by primer and bonding and cannot collapse. The smear layer and the depth of penetration of resin bonding in dentinal tubules are completely integrated into hybrid layer. The purpose of this laboratory research was to study the penetration depth of two self etching adhesive. Fourteen samples of human extracted teeth were divided into two groups. Each groups consisted of seven samples, each of them was treated with sixth generation bonding agent and the other was treated with seventh generation bonding agent. The results disclosed that the penetration into dentinal tubules of seventh generation bonding agent was deeper than sixth generation bonding agent. Conclusion: bond strength will improve due to the increasing of penetration depth of resin bonding in dentinal tubules.

  11. Conceptual development of the immune system as a sixth sense.

    Science.gov (United States)

    Blalock, J Edwin; Smith, Eric M

    2007-01-01

    Understanding how and why the immune and nervous systems communicate in a bidirectional pathway has been fundamental to the development of the psychoneuroimmunology (PNI) field. This review will discuss some of the pivotal results that found the nervous and immune systems use a common chemical language for intra and inter-system communication. Specifically the nervous and immune systems produce a common set of peptide and nonpeptide neurotransmitters and cytokines that provides a common repertoire of receptors and ligands between the two systems. These studies led to the concept that through the sharing of ligands and receptors the immune system could serve as a sixth sense to detect things the body cannot otherwise hear, see, smell, taste or touch. Pathogens, tumors, and allergens are detected with great sensitivity and specificity by the immune system. As a sixth sense the immune system is a means to signal and mobilize the body to respond to these types of challenges. The paper will also review in a chronological manner some of the PNI-related studies important to validating the sixth sense concept. Finally, the review will suggest ways to apply the new found knowledge of the sixth sense to understanding a placebo effect and developing new therapeutic approaches for treatment of human diseases.

  12. Transportation Energy Data Book. Sixth edition

    Kulp, G.; Holcomb, M. C.

    1982-01-01

    Designed for use as a desk-top reference, the data book represents an assembly and display of statistics that characterize transportation activity and presents data on other factors that influence transportation energy use. The purpose of this publication is to present a large amount of relevant data in an easily retrievable and usable format with the statistical data shown in the form of tables and graphs. Each of the major transportation modes (highway, air, water, rail, and pipeline) is treated separately, and aggregate energy use and energy supply data for all modes are presented. The highway mode, accounting for over 77% of total transportation energy consumption, is dealt with. Topics in this include vehicle stock characteristics, fuel efficiency, household vehicle ownership and use, fleet automobiles, buses, and trucks. Data are presented on each of the nonhighway modes: air, water, pipeline, and rail, respectively. Trends in vehicle and engine characteristics related to fuel economy are summarized. Emphasis is placed on vehicles and engines for highway use.

  13. The impact of environmental education on sixth-grade students' science achievement

    Science.gov (United States)

    Clavijo, Katherine Gillespie

    This study investigated the relationship between student involvement in environmental education (EE) and science achievement. The performance of students engaged in fifth and sixth grade classrooms identified as incorporating environmental education into science instruction was compared to that of students from similar classrooms that use traditional science instruction. Data from 4655 sixth grade students were analyzed using hierarchical multiple regression model to determine if environmental education improves prediction of science achievement beyond that afforded by differences in socioeconomic status and previous science achievement. The results indicated that environmental education, when integrated into science instruction, does not improve prediction of CTBS science scores beyond that afforded by differences in previous achievement in science and socioeconomic status. Previous achievement and socioeconomic status were the only two variables that predicted CTBS science subtest scores. The variable previous achievement (Score on fourth grade KIRIS test) explained 27.6% of the variance in CTBS test scores. The variable socioeconomic status (participation in free and reduced lunch program) explained 7.1% of the variance in CTBS science test scores. Participation in a fifth, sixth or both grades environmental education classroom did not add to the prediction of CTBS scores. This study illustrates that environmental education, while not correlated with high science achievement, does not correlate with low science achievement. Environmental education research may benefit from similar studies, which utilize alternative forms of student assessment. This study has implications for researchers interested in examining the impact of environmental education on science achievement, as it provides evidence for the importance of including background characteristics, such as socioeconomic status and previous achievement, in research models. This study provides an example of

  16. Does a sixth mechanism exist to explain lightning injuries?: investigating a possible new injury mechanism to determine the cause of injuries related to close lightning flashes.

    Science.gov (United States)

    Blumenthal, Ryan; Jandrell, Ian R; West, Nicholas J

    2012-09-01

    Five mechanisms have been described in the literature regarding lightning injury mechanisms. A sixth mechanism is proposed in this article, namely, lightning barotrauma. A simple laboratory experiment was conducted using ordnance gelatin for ballistic studies. Lightning was simulated in a high-voltage laboratory using an 8/20-microsecond current impulse generator and discharged through ballistic gel. Temporary and permanent cavity formations were confirmed. The cavities formed were directly proportional to the currents used. Findings suggest that a sixth mechanism of lightning injury, namely, barotrauma, should be considered.

    The LIGO gravitational wave detectors at the Hanford and Livingston Observatories are very sensitive to environmental effects, stationary or transient, which are a subtle and important source of noise and false positives. We present seismic, acoustic and magnetic influences in the sixth LIGO science run and explain some of the coupling mechanisms. The methods are general enough to be employed in the future, and will be used to measure the environmental influence in the more sensitive Advanced LIGO detectors currently being installed. This work was partially supported by the NSF grant PHY-0905184.

    Palaeontologists characterize mass extinctions as times when the Earth loses more than three-quarters of its species in a geologically short interval, as has happened only five times in the past 540 million years or so. Biologists now suggest that a sixth mass extinction may be under way, given the known species losses over the past few centuries and millennia. Here we review how differences between fossil and modern data and the addition of recently available palaeontological information influence our understanding of the current extinction crisis. Our results confirm that current extinction rates are higher than would be expected from the fossil record, highlighting the need for effective conservation measures.

    Like any artist, the paractitioner of the healing art should exactly know his tools, i.e. his medicines and the directions for their application. In addition, he should be able to rely on their genuineness. Regarding the tool "Organon", considerable uncertainty has been expressed by some physicians about the authenticity of Hahnemann's instructions for preparing and applying Q-potencies, as described in the sixth edition of the Organon of Medicine published by Richard Haehl in 1921. Since 1992, however, the first text-critical edition of the sixth edition of the Organonis available. Unlike Haehl's edition this one is exclusively based on Hahnemann's original manuscript and precisely transcribing all its handwriting, vouches for its authenticity. Hence there is no reason left to ignore Hahnemanns instructions concerning Q-potencies. This paper presents the history of the reception of Q-potencies as well as their prerequisites and evolution up to Hahnemann's final modifications of his earlier directions. As it turns out, these late instructions of Hahnemann do not mean complete change of all his previous opinions. Rather they are the logical completion of a course followed by him for ten years already. Q-potencies were Hahnemann's solution of the following therapeutic dilemma: on the one side physicians are inclined to repeat the dose of a high potency as often as possible in order to accelerate the process of healing; on the other side they should refrain from repeating the dose to avoid violent aggravations of the state of the patient.

    BACKGROUND: Cranial nerve palsies has several etiologies including vascular insufficiency, neoplasm, trauma and inflammation. Isolated sixth nerve palsy is an extremely rare presenting feature of leukemia. AIM: We describe an unusual ocular presentation of a bilateral progressive sixth nerve palsy in a young male with a preceding head injury. CONCLUSION: Acquired sixth nerve palsies in young adults may be due to trauma but in the absence of a definitive history other systemic processes must be outruled. We describe a case of bilateral sixth nerve palsy in a patient with ALL with no obvious CNS involvement. Potential etiological mechanisms are discussed.

    1995-12-31

    This report covers the sixth of an annual series of workshops held at the Aspen Center for Physics concentrating particularly on the identification of features in DNA sequence, and more broadly on related topics in computational molecular biology. The workshop series originally focused primarily on discussion of current needs and future strategies for identifying and predicting the presence of complex functional units on sequenced, but otherwise uncharacterized, genomic DNA. We addressed the need for computationally-based, automatic tools for synthesizing available data about individual consensus sequences and local compositional patterns into the composite objects (e.g., genes) that are -- as composite entities -- the true object of interest when scanning DNA sequences. The workshop was structured to promote sustained informal contact and exchange of expertise between molecular biologists, computer scientists, and mathematicians.

  14. Mimetic fandom and one-sixth-scale action figures

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available Within material practices that emphasize reproduction, customizers often extrapolate, creating new material to fill in gaps. Bricolage transforms mass-produced items into individualized creative works by improving the perceived accuracy of licensed merchandise or by recycling and repurposing items to achieve realistic and imaginative results. Customization's material fan practices reproduce items in order to create transformative narratives. After duplicating a beloved fan object's definitive appearance, clothing, and/or accessories in one-sixth scale, customizers often pose and photograph action figures in recreations of iconic scenes. Other images and photostories use miniature reproductions of material objects to rework existing media texts and characters or to tell completely original narratives. Images also disrupt and deconstruct the valorization of accuracy. Living rooms, pets, and other aspects of everyday life intrude into photographs of accurately reproduced items and characters. Figures in photostories may be made to break character. Such transformative moments call attention to the toys' status as toys and to the constructed nature of poses, dioramas, and narratives.

    2008-01-01

    Today's verification techniques are hard-pressed to scale with the ever-increasing complexity of safety critical systems. Within the field of aeronautics alone, we find the need for verification of algorithms for separation assurance, air traffic control, auto-pilot, Unmanned Aerial Vehicles (UAVs), adaptive avionics, automated decision authority, and much more. Recent advances in formal methods have made verifying more of these problems realistic. Thus we need to continually re-assess what we can solve now and identify the next barriers to overcome. Only through an exchange of ideas between theoreticians and practitioners from academia to industry can we extend formal methods for the verification of ever more challenging problem domains. This volume contains the extended abstracts of the talks presented at LFM 2008: The Sixth NASA Langley Formal Methods Workshop held on April 30 - May 2, 2008 in Newport News, Virginia, USA. The topics of interest that were listed in the call for abstracts were: advances in formal verification techniques; formal models of distributed computing; planning and scheduling; automated air traffic management; fault tolerance; hybrid systems/hybrid automata; embedded systems; safety critical applications; safety cases; accident/safety analysis.

    These proceedings contain contributions from about 200 participants to the 6th International Conference on Squeezed States and Uncertainty Relations (ICSSUR'99) held in Naples May 24-29, 1999, and organized jointly by the University of Naples "Federico II," the University of Maryland at College Park, and the Lebedev Institute, Moscow. This was the sixth of a series of very successful meetings started in 1990 at the College Park Campus of the University of Maryland. The other meetings in the series were held in Moscow (1992), Baltimore (1993), Taiyuan P.R.C. (1995) and Balatonfuered, Hungary (1997). The present one was held at the campus Monte Sant'Angelo of the University "Federico II" of Naples. The meeting sought to provide a forum for updating and reviewing a wide range of quantum optics disciplines, including device developments and applications, and related areas of quantum measurements and quantum noise. Over the years, the ICSSUR Conference evolved from a meeting on quantum measurement sector of quantum optics, to a wide range of quantum optics themes, including multifacet aspects of generation, measurement, and applications of nonclassical light (squeezed and Schrodinger cat radiation fields, etc.), and encompassing several related areas, ranging from quantum measurement to quantum noise. ICSSUR'99 brought together about 250 people active in the field of quantum optics, with special emphasis on nonclassical light sources and related areas. The Conference was organized in 8 Sections: Squeezed states and uncertainty relations; Harmonic oscillators and squeeze transformations; Methods of quantum interference and correlations; Quantum measurements; Generation and characterisation of non-classical light; Quantum noise; Quantum communication and information; and Quantum-like systems.

  20. "The sixth sense": towards a history of muscular sensation.

    Science.gov (United States)

    Smith, Roger

    2011-01-01

    This paper outlines the history of knowledge about the muscular sense and provides a bibliographic resource for further research. A range of different topics, questions and approaches have interrelated throughout this history, and the discussion clarifies this rather than presenting detailed research in any one area. Part I relates the origin of belief in a muscular sense to empiricist accounts of the contribution of the senses to knowledge from Locke, via the iddologues and other authors, to the second half of the nineteenth century. Analysis paid much attention to touch, first in the context of the theory of vision and then in its own right, which led to naming a distinct muscular sense. From 1800 to the present, there was much debate, the main lines of which this paper introduces, about the nature and function of what turned out to be a complex sense. A number of influential psycho-physiologists, notably Alexander Bain and Herbert Spencer, thought this sense the most primitive and primary of all, the origin of knowledge of world, causation and self as an active subject. Part II relates accounts of the muscular sense to the development of nervous physiology and of psychology. In the decades before 1900, the developing separation of philosophy, psychology and physiology as specialised disciplines divided up questions which earlier writers had discussed under the umbrella heading of muscular sensation. The term'kinaesthesia' came in 1880 and 'proprio-ception' in 1906. There was, all the same, a lasting interest in the argument that touch and muscular sensation are intrinsic to the existence of embodied being in the way the other senses are not. In the wider culture--the arts, sport, the psychophysiology of labour and so on--there were many ways in which people expressed appreciation of the importance of what the anatomist Charles Bell had called 'the sixth sense'.

    The sixth blind test of organic crystal structure prediction (CSP) methods has been held, with five target systems: a small nearly rigid molecule, a polymorphic former drug candidate, a chloride salt hydrate, a co-crystal and a bulky flexible molecule. This blind test has seen substantial growth in the number of participants, with the broad range of prediction methods giving a unique insight into the state of the art in the field. Significant progress has been seen in treating flexible molecules, usage of hierarchical approaches to ranking structures, the application of density-functional approximations, and the establishment of new workflows and ‘best practices’ for performing CSP calculations. All of the targets, apart from a single potentially disordered Z′ = 2 polymorph of the drug candidate, were predicted by at least one submission. Despite many remaining challenges, it is clear that CSP methods are becoming more applicable to a wider range of real systems, including salts, hydrates and larger flexible molecules. The results also highlight the potential for CSP calculations to complement and augment experimental studies of organic solid forms. PMID:27484368

    The sixth International Conference on Gravitation & Cosmology (ICGC-2007) was organized at IUCAA, Pune, 17-21 December 2007. This series of international meetings, held every four years under the auspices of the Indian Association for General Relativity and Gravitation (IAGRG), has now spanned two decades. Previous ICGC meetings were held at Cochin University of Science and Technology (2004), Indian Institute of Technology, Kharagpur (2000), IUCAA, Pune (1995), Physical Research Laboratory, Ahmedabad (1991) & Goa (1987). These meetings have broad international participation and feature leading experts in the field of Cosmology, gravitational waves and quantum gravity. The frontier of research in Gravitation and Cosmology has seen remarkable progress in the past decades. On the theoretical front, black holes and cosmological singularities continue to challenge and attract quantum gravity researchers. The quest for the detection of Gravitational waves and the promise of gravitational wave astronomy continues to grow and breakthroughs of the past couple of years indicate that numerical relativity is catching up too. The past few years have also seen very ambitious experimental efforts to verify general relativity as the theory of gravitation. Cosmology has been veritably transformed into a precision science with the tremendous improvement in the quantity and quality of cosmological observations. The exquisite measurements not only allow refinement of the cosmological model parameters but have begun to allow observational tests of underlying fundamental assumptions and hunt for subtle deviations that could be the key to understanding the early universe. The sixth meeting brought together active scientists from all over the globe to present the state of the art at the frontiers of research. It also offered younger Indian researchers an opportunity for interaction with experts from within India and abroad. The meeting was attended by over 160 participants. The scientific

    Full Text Available Aims: The aim was to assess the etiology of sixth nerve palsy and on the basis of our data, to formulate a diagnostic algorithm for the management in sixth nerve palsy. Design: Retrospective chart review. Results: Of the 104 neurologically isolated cases, 9 cases were attributable to trauma, and 95 (86.36% cases were classified as nontraumatic, neurologically isolated cases. Of the 95 nontraumatic, isolated cases of sixth nerve palsy, 52 cases were associated with vasculopathic risk factors, namely diabetes and hypertension and were classified as vasculopathic sixth nerve palsy (54.7%, and those with a history of sixth nerve palsy from birth (6 cases were classified as congenital sixth nerve palsy (6.3%. Of the rest, neuroimaging alone yielded a cause in 18 of the 37 cases (48.64%. Of the other 19 cases where neuroimaging did not yield a cause, 6 cases were attributed to preceding history of infection (3 upper respiratory tract infection and 3 viral illnesses, 2 cases of sixth nerve palsy were found to be a false localizing sign in idiopathic intracranial hypertension and in 11 cases, the cause was undetermined. In these idiopathic cases of isolated sixth nerve palsy, neuroimaging yielded no positive findings. Conclusions: In the absence of risk factors, a suggestive history, or positive laboratory and clinical findings, neuroimaging can serve as a useful diagnostic tool in identifying the exact cause of sixth nerve palsy. Furthermore, we recommend an algorithm to assess the need for neuroimaging in sixth nerve palsy.

    A new 9-point sixth-order accurate compact finite-difference method for solving the Helmholtz equation in one and two dimensions, is developed and analyzed. This scheme is based on sixth-order approximation to the derivative calculated from the Helmholtz equation. A sixth-order accurate symmetrical representation for the Neumann boundary condition was also developed. The efficiency and accuracy of the scheme is validated by its application to two test problems which have exact solutions. Numerical results show that this sixth-order scheme has the expected accuracy and behaves robustly with respect to the wave number.

  16. Realizing the child's perspective: An exploration of sixth-graders' ideas about land use

    Science.gov (United States)

    Wee, Bryan Shao-Chang

    Given the rapid rate of urbanization in the U.S., it is important to explore children's conceptions of land use and to understand children's relationships to the environment. In addition, the school is an important source of environmental information where curriculum and instruction play critical roles in shaping children's ideas. The purpose of this study, therefore, was to investigate children's conceptions of land use in the context of an environmental science class. This was a naturalistic study conducted with 13 sixth-graders and their teacher in West-central Indiana. A social constructivist framework was utilized to steer data collection and to guide interpretation. Qualitative methods such as interviews, drawings and photograph journals were used to elicit children's ideas and field notes provided a rich description of the learning environment. Data were analyzed inductively and coded using case-specific criteria to organize and interpret data on an emergent basis. It was found that children in this study did not view humans as part of the environment. Land use was conceptualized as a human activity for human benefit, that is, children's conceptions of land use were framed by an anthropocentric worldview. Furthermore, children's conceptions of land use-related outcomes were negative and limited to large-scale, visible forms of environmental impacts. Environmental science instruction did not change these ideas; in fact, they were reinforced by the school curriculum. These findings suggest that exploring and applying the fundamental nature of children's ideas in environmental education and research is essential to the development of a land ethic as well as an environmentally literate citizenry.

  1. Sixth hour transcutaneous bilirubin predicting significant hyperbilirubinemia in ABO incompatible neonates

    Institute of Scientific and Technical Information of China (English)

    Ramesh Y Bhat; Pavan CG Kumar

    2014-01-01

    Background: Neonates with ABO hemolytic disease are at greater risk for developing significant hyperbilirubinemia. We aimed to determine whether sixth hour transcutaneous bilirubin (TcB) could predict such a risk. Methods: TcB measurements were obtained at the 6th hour of life in blood group A or B neonates born to blood group O, rhesus factor compatible mothers. Subsequent hyperbilirubinemia was monitored and considered significant if a neonate required phototherapy/exchange transfusion. The predictive role of sixth hour TcB was estimated. Results: Of 144 ABO incompatible neonates, 41(OA, 24; O-B, 17) had significant hyperbilirubinemia. Mean sixth hour TcB was significantly higher among neonates who developed significant hyperbilirubinemia than those who did not (5.83±1.35 mg/dL vs. 3.65±0.96 mg/dL, P4 mg/dL had the highest sensitivity of 93.5% and >6 mg/dL had the highest specifi city of 99%. Area under receiver operating characteristic curve was 0.898. Conclusion: Sixth hour TcB predicts subsequent significant hyperbilirubinemia in ABO incompatible neonates.

    Directory of Open Access Journals (Sweden)

    Anne H. Zachry

    2016-04-01

    Full Text Available Background: Handwriting is an important skill to master because handwriting demands take up a significant portion of the school day. Pediatric occupational therapists evaluate and treat children who are experiencing challenges with handwriting; therefore, it is important for practitioners to understand the performance of children using both of these writing styles. Method: A convenience sample of 36 fifth and sixth grade students participated in the study. Print and cursive handwriting samples were collected on two separate occasions, and a Wilcoxon-Mann-Whitney test was used to examine speed and legibility differences in these writing styles. Results: Speed in print writing did not differ significantly for gender between the fifth and sixth graders. Cursive writing speed improved significantly for the sixth grade female students compared to the fifth grade female students. Female print legibility scores decreased from the fifth to the sixth grade. Regardless of grade level, the female students were faster with cursive than the male students. Conclusion: The female students consistently used cursive, and their writing speed increased from one year to the next, as compared to the male students, who did not use a consistent writing style. It is important for occupational therapists to educate teachers and parents on the importance of consistent handwriting instruction and practice.

  13. Does the vagus nerve mediate the sixth sense?

    Science.gov (United States)

    Zagon, A

    2001-11-01

    Can sensations originating from the internal environment modulate attitude and behaviour? Can the feedback about the operation of the viscera provide a calming and relaxing influence? Information from the chest and abdomen is delivered continuously by the vagus nerve, the largest visceral sensory nerve in the body. Because various 'stress-related' diseases can be associated with impaired functions in sensory vagal fibres, a better understanding of how sensory vagal information is processed in the CNS might offer new strategies for the treatment and/or prevention of several disorders, including 'drug-resistant' forms of eating disorder, anxiety, chronic depression and epilepsy. A neuronal circuitry that has been suggested by experimental data to mediate sensory vagal inputs to those brain areas that are involved in the generation of 'stress-related' disorders is outlined.

  14. Random matrix theory and the sixth Painleve equation

    Energy Technology Data Exchange (ETDEWEB)

    Forrester, P J; Witte, N S [Department of Mathematics and Statistics, University of Melbourne, Victoria 3010 (Australia)

    2006-09-29

    A feature of certain ensembles of random matrices is that the corresponding measure is invariant under conjugation by unitary matrices. Study of such ensembles realized by matrices with Gaussian entries leads to statistical quantities related to the eigenspectrum, such as the distribution of the largest eigenvalue, which can be expressed as multidimensional integrals or equivalently as determinants. These distributions are well known to be {tau}-functions for Painleve systems, allowing for the former to be characterized as the solution of certain nonlinear equations. We consider the random matrix ensembles for which the nonlinear equation is the {sigma} form of P{sub VI}. Known results are reviewed, as is their implication by way of series expansions for the distributions. New results are given for the boundary conditions in the neighbourhood of the fixed singularities at t = 0, 1, {infinity} of {sigma}P{sub VI} displayed by a generalization of the generating function for the distributions. The structure of these expansions is related to Jimbo's general expansions for the {tau}-function of {sigma}P{sub VI} in the neighbourhood of its fixed singularities, and this theory is itself put in its context of the linear isomonodromy problem relating to P{sub VI}.

  15. A Sixth-order Image Approximation to the Ionic Solvent Induced Reaction Field.

    Science.gov (United States)

    Xiang, Ming; Deng, Shaozhong; Cai, Wei

    2009-12-01

    A recent article by Deng and Cai introduced fourth-order image approximations to the reaction field for a charge inside a dielectric sphere immersed in a solvent of low ionic strength. To represent such a reaction field, the image approximations employ a point charge at the classical Kelvin image point and two line charges that extend from the Kelvin image point along the radial direction to infinity. In this paper, a sixth-order image approximation is developed, using the same point charge with three different line charges. Procedures on how to discretize the line charges by point image charges and how to implement the resulting point image approximation in O(N) complexity for potential and force field calculations are included. Numerical results demonstrate the sixth-order convergence rate of the image approximation and the O(N) complexity of the fast implementation of the point image approximation.

  16. Raising voices: How sixth graders construct authority and knowledge in argumentative essays

    Science.gov (United States)

    Monahan, Mary Elizabeth

    This qualitative classroom-based study documents one teacher-researcher's response to the "voice" debate in composition studies and to the opposing views expressed by Elbow and Bartholomae. The author uses Bakhtin's principle of dialogism, Hymes's theory of communicative competence, as well as Ivanic's discussion of discoursally constructed identities to reconceptualize voice and to redesign writing instruction in her sixth grade classroom. This study shows how students, by redefining and then acting on that voice pedagogy in terms that made sense to them, shaped the author's understanding of what counts as "voiced" writing in non-narrative discourse. Based on a grounded-theory analysis of the twenty-six sixth graders' argumentative essays in science, the author explains voice, not as a property of writers or of texts, but as a process of "knowing together"---a collaborative, but not entirely congenial, exercise of establishing one's authority by talking with, against, and through other voices on the issue. As the results of this study show, the students' "I-Ness" or authorial presence within their texts, was born in a nexus of relationships with "rivals," "allies" and "readers." Given their teacher's injunctions to project confidence and authority in argumentative writing, the students assumed fairly adversarial stances toward these conversational partners throughout their essays. Exaggerating the terms for voiced writing built into the curriculum, the sixth graders produced essays that read more like caricatures than examples of argumentation. Their displays of rhetorical bravado and intellectual aggressiveness, however offsetting to the reader, still enabled these sixth graders to composed voiced essays. This study raises doubts about the value of urging students to sound like their "true selves" or to adopt the formal registers of academe. Students, it seems clear, stand to gain by experimenting with a range of textual identities. The author suggests that voice

    Full Text Available The primary aim of this study is to define reaching of attainment levels of algebra learning domain in sixth grade of elementary mathematics education program. In the study; it has been fulfilled in descriptive featured scanning model because the existing case was tried to define. 510 sixth grade students, determined by stratified sampling method among Elementary Schools in Balıkesir city centre, have applied into the study. As data collecting tool, pre and post test has been used to define the level in obtaining acquisitions of Algebra learning domain in sixth grade of Elementary Mathematics course curriculum applications. Acquired data have been evaluated by using descriptive analysis, t test for related samples and covariance analysis. Effect sizes correlation coefficient was also calculated. In consequence of the study it has been concluded that the students’Algebra test point averages are meaningful in favor of the post -test (p<.05,as a result of Algebra learning domain applications in elementary school sixth grade of Elementary Mathematics course curriculum, but for the reason that the post -test’s absolute success point averages are under 0.75, the complete learning level has notbeen reached, that the students’ obtaining just about %57 of the acquisitions at the level of 75 has shown that the learning process are not as sufficient as expected level for providing accessibility of learning process’ acquisitions, and that students’ level,studying in upper group schools, in attaining acquisitions are highercompared to those in middle and lower group schools, and when the students’ pretest results are taken under control, obtained post test’s corrected results have also significant difference

    2013-01-01

    We study a sixth order derivative scalar field model in Minkowski spacetime as a toy model of higher-derivative critical gravity theories. This model is consistently quantized when using the Becchi-Rouet-Stora-Tyutin (BRST) quantization scheme even though it does not show gauge symmetry manifestly. Imposing a BRST quartet generated by two scalars and ghosts, there remains a non-trivial subspace with positive norm.

    We report a 57-year-old woman with neuroborreliosis presenting with headache, shoulder muscle pain and double vision. MRI demonstrated enhancement of the right third and sixth cranial nerves. A 3D MP-RAGE sequence was used to perform multiplanar reformations to show this more graphically. The patient was free of symptoms 1 month after completion of therapy, when thickening and contrast enhancement of the nerves were less pronounced. (orig.)

    Full Text Available In this paper, we develop new families of sixth-order methods for solving simple zeros of non-linear equations. These methods are constructed such that the convergence is of order six. Each member of the families requires two evaluations of the given function and two of its derivative per iteration. These methods have more advantages than Newton’s method and other methods with the same convergence order, as shown in the illustration examples.

    The oft-repeated claim that Earth’s biota is entering a sixth “mass extinction” depends on clearly demonstrating that current extinction rates are far above the “background” rates prevailing between the five previous mass extinctions. Earlier estimates of extinction rates have been criticized for using assumptions that might overestimate the severity of the extinction crisis. We assess, using extremely conservative assumptions, whether human activities are causing a mass extinction. First, we...

    Full Text Available We study the initial boundary value problem for a sixth-order Cahn-Hilliard-type equation which describes the separation properties of oil-water mixtures, when a substance enforcing the mixing of the phases is added. We show that the solutions might not be classical globally. In other words, in some cases, the classical solutions exist globally, while in some other cases, such solutions blow up at a finite time. We also discuss the existence of global attractor.

  14. The effects of collaborative video production on the attitudes and science knowledge of sixth graders

    Science.gov (United States)

    Gaston, Joseph Pickett

    This quantitative study examined the effects of collaborative video production (CVP) on the attitudes and conceptual understanding of sixth-grade science students at a public middle school in the Southeastern United States. This study followed the nonequivalent control group design, as described by Campbell and Stanley (1963). The study involved four classes of sixth-grade students. The two control classes were taught the science concept by the cooperating teacher through direct instruction, and the two experimental classes learned the science concept through the CVP project. Pre- and posttests were administered to all students, as well as two pre- and post-surveys measuring student attitudes towards science and technology. Analysis of covariance (ANCOVA) with the pretest scores as the covariate (Xc) was conducted with the posttest and post-survey data to determine if a significant difference existed in scores between the two groups. In each case, no significant difference was found. The results of this study suggest that CVP was as effective at conveying conceptual understanding to sixth-grade science students as direct instruction. Although not significant, the study also showed that mean scores of students' attitudes towards science and technology increased from pre-surveys to post-surveys for those who participated in the CVP activity. These findings suggest that the treatment contributed to an increase in participants' attitudes and towards technology and the academic subject. No such increase in mean post-survey scores existed for students receiving direct instruction.

    Full Text Available Problem statement: This study aims to investigate factors influencing mathematic problem-solving ability of sixth grade students. One thousand and twenty eight of sixth grade students, studying in the second semester of academic year 2007 were sampled by stratified random sampling technique. Approach: The research instruments used in the study included mathematic problem-solving ability test and questionnaires. Data was analyzed by Path Analysis. Results: Factors influencing mathematic problem-solving ability were represented as following: (1 direct factors influencing mathematic problem-solving ability were described that direct and indirect factors influencing mathematic problem-solving ability were attitude towards mathematics, self-esteem and teachers’ teaching behavior. Indirect factors influencing mathematic problem-solving ability were motivation and self-efficacy (2 factor models influencing mathematic problem-solving ability of sixth grade students was associated with visual data (3 The developed model could describe variance of skill in mathematic problem-solving at 63.00 % (R2 = 0.63. Conclusion: Teacher’s behaviors took both direct and indirect effects on the students’ mathematic problem solving. The teachers are supposed to study the methods to develop this ability deeply and then bring them to manage the activities in class that encourage students to be enthusiastic to learn and have good attitude toward mathematic learning or to get students’ concentration.

    The Justinianic Plague, which started in the sixth century and lasted to the mid eighth century, is thought to be the first of three historically documented plague pandemics causing massive casualties. Historical accounts and molecular data suggest the bacterium Yersinia pestis as its etiological agent. Here we present a new high-coverage (17.9-fold) Y. pestis genome obtained from a sixth-century skeleton recovered from a southern German burial site close to Munich. The reconstructed genome enabled the detection of 30 unique substitutions as well as structural differences that have not been previously described. We report indels affecting a lacl family transcription regulator gene as well as nonsynonymous substitutions in the nrdE, fadJ, and pcp genes, that have been suggested as plague virulence determinants or have been shown to be upregulated in different models of plague infection. In addition, we identify 19 false positive substitutions in a previously published lower-coverage Y. pestis genome from another archaeological site of the same time period and geographical region that is otherwise genetically identical to the high-coverage genome sequence reported here, suggesting low-genetic diversity of the plague during the sixth century in rural southern Germany. © The Author 2016.

    2014-02-01

    Full Text Available After collecting the essential historical, archaeological, and artistic information relative to the ancient town of Nikopolis in Epirus and its Alpha (or Doumetios Basilica, built in the sixth century A.D., glass tesserae belonging to degraded and lost parts of the mosaic floors of the basilica were analysed, determining their chemical composition and the possible presence of crystalline phases. As in all glasses produced in the Mediterranean area in that epoch, they are soda-lime silicate glasses, in part with lead, obtained using natron as a flux. The typology of the glass corresponds to that of Roman glasses, of the first centuries A.D., and is the same as that employed for the basilicas of Ravenna in the fifth and sixth centuries; in particular, a comparison was made with the glass tesserae of the St Vitale Basilica. The technological base for producing coloured glasses is also practically the same as that of the mosaic glasses of Ravenna. In particular, antimony was used as an opacifying element and a fusion was carried out under reducing conditions to obtain red glass with microparticles of metallic copper. Thus, it can be supposed there was a common source of production of the mosaic glasses used in Nikopolis and Ravenna in the sixth century and that this source was in the Near Orient.

  20. Behavior and finite-size effects of the sixth order cumulant in the three-dimensional Ising universality class

    Pan, Xue; Chen, Li-Zhu; Wu, Yuan-Fang

    2016-09-01

    The high-order cumulants of conserved charges are suggested to be sensitive observables to search for the critical point of Quantum Chromodynamics (QCD). This has been calculated to the sixth order in experiments. Corresponding theoretical studies on the sixth order cumulant are necessary. Based on the universality of the critical behavior, we study the temperature dependence of the sixth order cumulant of the order parameter using the parametric representation of the three-dimensional Ising model, which is expected to be in the same universality class as QCD. The density plot of the sign of the sixth order cumulant is shown on the temperature and external magnetic field plane. We found that at non-zero external magnetic field, when the critical point is approached from the crossover side, the sixth order cumulant has a negative valley. The width of the negative valley narrows with decreasing external field. Qualitatively, the trend is similar to the result of Monte Carlo simulation on a finite-size system. Quantitatively, the temperature of the sign change is different. Through Monte Carlo simulation of the Ising model, we calculated the sixth order cumulant of different sizes of systems. We discuss the finite-size effects on the temperature at which the cumulant changes sign.

    Waterpipe tobacco smoking (WTS) is highly prevalent in the Eastern Mediterranean region. While studies have identified socio-demographic factors differentiating smokers from non-smokers, validated tools predicting WTS are lacking. Over 1000 (n = 1164) sixth and seventh grade students in Lebanon were randomly assigned to a prediction model group and validation model group. In the prediction model group, backward stepwise logistic regression enabled the identification of socio-demographic and psychosocial factors associated with ever and current WTS. This formed risk scores which were tested on the validation model group. The risk score for current WTS was out of four and included reduced religiosity, cigarette use and the perception that WTS was associated with a good time. The risk score for ever WTS was out of seven and included an additional two variables: increased age and the belief that WTS did not cause oral cancer. In the validation model group, the model displayed moderate discrimination [area under the curve: 0.77 (current), 0.68 (ever)], excellent goodness-of-fit (P > 0.05 for both) and optimal sensitivity and specificity of 80.1 and 58.4% (current), and 39.5 and 94.4%, (ever), respectively. WTS use can be predicted using simple validated tools. These can direct health promotion and legislative interventions. © The Author 2015.

    Full Text Available There are only six cataracts on the Main Nile of which the sixth Nile cataract located ca. 80 km downstream of the confluence of the Blue and White Niles represents the southernmost and smallest of theseries. Despite its close vicinity to Khartoum, this area was the least studied cataract zone along the Middle Nile until 2009 when it became the object of geoarchaeological research by the Czech Institute of Egyptology (Faculty of Arts, Charles University in Prague and the Institute of Geology (Academy of Sciences of the Czech Republic. Four field campaigns have been carried out in Jebel Sabaloka and the Sixth Nile Cataract up to now, of which the first two were focused on landscape archaeology of a “large scale”, i.e. on the recognition of all observable human influencesin the research area of approx. 15×20 km. The main result of the first landscape archaeological reconnaissance consistsin the localisation and first description of ca. 30 major sites spanning from the Middle Palaeolithic up to the recent past. A peculiar archaeological feature of this part of the nile Valley has turned out to be the existence of a dense network of terraced “villages” connected via old paths with the Nile and with the periphery of the mountains. Furthermore, two Christian and Islamic forts have been found at places guarding the crossing of the Nile above the sixth cataract. Last but not least, a large number of prehistoric sites, including an extraordinarily rich settlement dated to the Mesolithic and Neolithic periods, has been described as well. After the first two seasons, the findings of which are summarised in this paper, it can be argued that the last of the six Nile cataracts to be investigated has finally begun to reveal its rich and hitherto unknown archaeological past.

    We study a sixth-order derivative scalar field model in Minkowski spacetime as a toy model of higher-derivative critical gravity theories. This model is consistently quantized when using the Becchi-Rouet-Stora-Tyutin (BRST) quantization scheme even though it does not show gauge symmetry manifestly. Imposing a BRST quartet generated by two scalars and ghosts, there remains a nontrivial subspace with positive norm. This might be interpreted as a Minkowskian dual version of the unitary truncation in the logarithmic conformal field theory.

    A recent article by Deng and Cai introduced fourth-order image approximations to the reaction field for a charge inside a dielectric sphere immersed in a solvent of low ionic strength. To represent such a reaction field, the image approximations employ a point charge at the classical Kelvin image point and two line charges that extend from the Kelvin image point along the radial direction to infinity. In this paper, a sixth-order image approximation is developed, using the same point charge w...

    In this letter, we analyse two bidirectional sixth-order partial differential equations, which are reductions in (1 + 1) dimensions of equations belonging to the KP hierarchy. They have fourth-order and fifth-order Lax pairs, respectively. We derive their Baecklund transformations and, from the nonlinear superposition formula, we can build their soliton solutions like a Grammian. The interesting dynamics of these solitons is that they may describe not only the overtaking collision but also the head-on collision of solitary waves of different type and shape.

    For the sixth Sea-Viewing Wide Field-of-View Sensor (SeaWiFS) Intercalibration Round-Robin Experiment (SIRREX-6), NASA personnel carried the same four Satlantic in-water radiometers to nine separate laboratories and calibrated them. Two of the sensors were seven-channel radiance heads and two were seven-channel irradiance heads. The calibration and data reduction procedures used at each site followed that laboratory's normal procedures. The reference lamps normally used for the calibration of these types of instruments by the various laboratories were also used for this experiment. NASA personnel processed the data to produce calibration parameters from the various laboratories

  12. The dispersion of pederasty and the athletic revolution in sixth-century BC Greece.

    Science.gov (United States)

    Scanlon, Thomas F

    2005-01-01

    Dorian Crete and Thebes are conventionally seen by ancient sources as the originators of pederasty; modern historians see support for this view in Dorian male-centered militarism and sexual segregation in upbringing. Here athletic culture, including training, nudism, and competition, is argued to be a chief 'trigger' for the emergence of pederasty in Sparta and its relatively rapid spread to other Greek states in the seventh to sixth centuries BC. Athletic nudity, in particular, was not a device to enforce civic egalitarianism, as some have argued, but is a persistently erotic incentive that reinforces hegemonic maleness and advertises the individual's virtuous exercise of restraint. In particular, Sparta is found to be the likely source of generalized athletic nudity combined with open pederasty in the early seventh century BC. Nudism in Greek art is erotically charged and not, as others argue, simply a gender marker in the seventh century. Generalized athletic nudity spread to other Greek states emulating the successful Spartan model by the 'athletic revolution' of the early sixth century. With athletic nudity, open pederasty, again following Sparta, was fostered.

    A 32-year-old pregnant woman developed a progressive right sixth cranial nerve palsy as an isolated finding. Brain MRI disclosed a discrete lobulated lesion centered in the right Meckel's cave with intermediate signal on T1, high signal on T2, and diffusion characteristics similar to those of cerebrospinal fluid on apparent diffusion coefficient mapping. The initial radiologic diagnosis was schwannoma or meningioma. No intervention occurred. Shortly after cesarean delivery, the abduction deficit began to lessen spontaneously. One month later, the abduction deficit had further improved; 7 months later it had completely resolved. Repeat MRI after delivery failed to disclose the lesion, which was now interpreted as consistent with an arachnoid cyst arising within Meckel's cave. Twenty-one similar cases of Meckel's cave arachnoid cyst or meningocele have been reported, 7 found incidentally and 14 causing symptoms, 2 of which produced ipsilateral sixth cranial nerve palsies. All previously reported symptomatic patients were treated surgically. This is the first report of an arachnoid cyst arising from Meckel's cave in pregnancy and having spontaneous resolution.

    Full Text Available The purpose of the study was to examine self-concept in relation to sport participation among basic school children. The sample included 109 sixth grade students of different Slovenian basic schools. The participants completed the Slovenian version of the SelfPerception Profile for Children – SPPC. The results show significant gender differences in some specific components of self-concept. Boys exhibited higher scores in perceived physical appearance and athletic competence, whereas girls exhibited higher levels in perceived behavioural conduct. Mean values show that students, engaged in organized sport practice, reported higher scores in all self-concept subscales than their inactive peers, although significant differences between these two groups were found in perceived scholastic competence and athletic competence. The study offers a detailed insight into the multidimensional self-perceptions of sixth grade basic school students. The results highlight the importance of physical/sports activity in the self-concept development and can be useful in promoting an active lifestyle among youth.

  15. The search for a sixth sense: the cases for vestibular, muscle, and temperature senses.

    Science.gov (United States)

    Wade, Nicholas J

    2003-06-01

    The five senses of sight, hearing, smell, taste, and touch, enumerated by Aristotle, were incremented in the early-nineteenth century by the muscle sense, multiple dimensions of touch, and a movement sense. Aristotle explicitly excluded a sixth sense, and five remains the number of senses in popular imagination. The division of touch into several sensations was entertained and rejected by Aristotle, but it was given anatomical, physiological and psychophysical support in the late-nineteenth century. A separate muscle sense was proposed in the late-eighteenth century, with experimental evidence to support it. However, before these developments, behavioral evidence of the vestibular (movement) sense was available from studies of vertigo, although it was not integrated with the anatomy and physiology of the labyrinth until the nineteenth century. The history of the search for a sixth sense is outlined, and the evidence adduced to support the divisions is assessed. Behavioral evidence generally has been accorded less weight than that from anatomy and physiology.

    Full Text Available Background and Aims: Composite restorative materials and dental adhesives are usually cured with light sources. The light direction may influence the bond strength of dental adhesives. The aim of this study was to evaluate the effect of light direction on the microtensile bond strength of fifth and sixth generation dental adhesives.Materials and Methods: Prime & Bond NT and Clearfil SE bond were used with different light directions.Sixty human incisor teeth were divided into 4 groups (n=15. In groups A and C, Clearfil SE bond with light curing direction from buccal was used for bonding a composite resin to dentin. In groups B and D, Prime & Bond NT with light curing direction from composite was used. After thermocycling the specimens were subjected to tensile force until debonding occurred and values for microtensile bond strength were recorded. The data were analyzed using two-way ANOVA and Tukey post hoc test.Results: The findings showed that the bond strength of Clearfil SE bond was significantly higher than that of Prime&Bond NT (P<0.001. There was no significant difference between light curing directions (P=0.132.Conclusion: Light curing direction did not have significant effect on the bond strength. Sixth generation adhesives was more successful than fifth generation in terms of bond strength to dentin.

The density plot of the sign of the sixth order cumulant is shown on the temperature and external magnetic field plane. We found that when the critical point is approached from the crossover side, the sixth order cumulant is negative. Qualitatively, the trend is similar to the result of Monte Carlo simulation on a finite-size system. Quantitatively, the temperature of the sign change is different.

    The conversion efficiency on the sixth harmonic of 1064 nm in KBe2BO3F2 (KBBF) at different gas pressures in two kinds of gases, helium and nitrogen, is measured and compared. In the both gases, maximum conversion efficiency on the sixth harmonic of 1064 nm in high vacuum is nearly 10% of 355 nm, which is almost four times higher than that in low vacuum. The maximum average output power at 177.3 nm is 670 μW with the repetition rate of 10 Hz and the duration of 20 ps in high vacuum. It indicates that the sixth harmonic generation in high vacuum is more preferable than that in low vacuum.

    The quasi-experimental study investigated sixth and eighth graders' perceptions of science with gender, grade levels, and educational experiences as the variables. The Theory of Planned Behavior (Ajzen, 1985) claims that attitude toward the behavior, subjective norm, and perceived behavioral control play a major role in people's intentions, and these intentions ultimately impact their behavior. The study adopted a quantitative research approach by conducting a science perceptions survey for examining students' self-efficacy in learning science (i.e., perceived behavioral control), value of science (i.e., attitude toward the behavior), motivation in science (i.e., attitude toward the behavior), and perceptions of digital science games in science classes (i.e., perceived behavioral control). A total of 255 participants' responses from four rural Appalachian middle school science classrooms in southeastern Ohio were analyzed through a three-way ANCOVA factorial pre-test and post-test data analysis with experimental and comparison groups. Additionally, the study applied a semi-structured, in-depth interview as a qualitative research approach to further examine STEAM digital science games' and Fellows' impact on students' perceptions of science. Eight students in the experimental group were interviewed. Interview data were analyzed with an inductive method. The results found in the three-way ANCOVA data analysis indicated that the diversity of educational experiences was a significant factor that impacted sixth and eighth graders' perceptions of science. Additionally, the interaction of gender and educational experiences was another significant factor that impacted sixth and eighth graders' perceptions of science. The findings of the two short-answer questions identified the reasons why the participants liked or disliked science, as well as why the participants would or would not choose a career in science. The conclusions of the semi-structured, in-depth interview

    The Sixth Annual Vaccine Renaissance Conference, hosted by the Institute for Immunology and Informatics (iCubed) at the University of Rhode Island (URI), took place on October 15-17, 2012. This conference provides a forum for the review of current progress in the discovery and development of vaccines, and creates an environment for the exchange of ideas. Dr. Joel McCleary opened the conference with a warning about the importance of preparing for well-defined biowarfare threats, including tularemia and Staphylococcal enterotoxin B. Following the keynote address, sessions explored biodefense and preparation for pandemic and biowarfare threats; vaccines for emerging and re-emerging neglected tropical diseases; animal vaccines and human health; and vaccine vectors and the human microbiome. In this issue of Human Vaccines and Immunotherapeutics, seven Vaccine Renaissance Conference speakers will showcase their work; here, we describe a few of the conference highlights.

    Mathematics education research has documented several classroom practices that might influence student self-regulation. We know little, however, about the ways these classroom practices could be structured in real classroom settings. In this exploratory case study, we purposefully selected a sixth-grade mathematics teacher who had participated in a professional development program focussed on NCTM standards and SRL in the mathematics classroom for extensive classroom observation. The purpose was to explore how and to what extend she structured classroom practices to support strategic competence in her students. Four features of classroom practices were found as evidence for how strategic competence was potentially supported in this classroom: (a) allowing autonomy and shared responsibility during the early stages of learning, (b) focusing on student understanding, (c) creating contexts for students to learn about strategic learning and to exercise strategic behaviour, and (d) helping students to personalise strategies by recognising their ideas and strategic behaviours.

  5. The Value of Supplementing Science Education with Outdoor Instruction for Sixth Grade Students

    Jackson, Devin Joseph Guilford

    Science education is moving away from memorization of facts to inquiry based learning. Adding outdoor instruction can be an effective way to promote this exploratory method of learning. The limited number of empirical studies available have shown significant increase in attitudes and learning with outdoor science instruction. An eight-week quasi-experimental teacher research study was conducted to further this research and assess the value of schoolyard science instruction on student engagement and learning. Participants were 60 students in two sixth grade middle school Earth Science classes. A crossover study design was used with two classes alternating as experimental and control groups. NASA Global Precipitation Measurement mission curriculum was used (NASA/GPM, 2011). While the results did not show a clear increase in student engagement and content knowledge, the study adds to the body of knowledge on outdoor instruction and identifies limitations to consider in future studies.

    An approximate homotopy symmetry method for nonlinear problems is proposed and applied to the sixth-order Boussinesq equation,which arises from fluid dynamics.We summarize the general formulas for similarity reduction solutions and similarity reduction equations of different orders,educing the related homotopy series solutions.Zero-order similarity reduction equations are equivalent to the Painlevé IV type equation or Weierstrass elliptic equation.Higher order similarity solutions can be obtained by solving linear variable coefficients ordinary differential equations.The auxiliary parameter has an effect on the convergence of homotopy series solutions.Series solutions and similarity reduction equations from the approximate symmetry method can be retrieved from the approximate homotopy symmetry method.

    2013-01-01

    Full Text Available This study aims to produce numerical solutions of one-dimensional advection-diffusion equation using a sixth-order compact difference scheme in space and a fourth-order Runge-Kutta scheme in time. The suggested scheme here has been seen to be very accurate and a relatively flexible solution approach in solving the contaminant transport equation for Pe≤5. For the solution of the present equation, the combined technique has been used instead of conventional solution techniques. The accuracy and validity of the numerical model are verified through the presented results and the literature. The computed results showed that the use of the current method in the simulation is very applicable for the solution of the advection-diffusion equation. The present technique is seen to be a very reliable alternative to existing techniques for these kinds of applications.

    1999-01-01

    A Miura chain is a (closed) sequence of differential (or difference) equations that are related by Miura or Bäcklund transformations. We describe such a chain for the sixth Painlevé equation (\\pvi), containing, apart from ordinary differential equation (ODE). As a byproduct we derive an auto-Bäcklund transformation, relating two copies of \\pvi with different parameters. We also establish the analogous ordinary difference equations in the discrete counterpart of the chain. Such difference equations govern iterations of solutions of \\pvi under Bäcklund transformations. Both discrete and continuous equations constitute a larger system which include partial difference equations, differential-difference equations and partial differential equations, all associated with the lattice Korteweg-de Vries equation subject to similarity constraints.

  13. The nucleon-nucleon interaction up to sixth order in the chiral expansion

    Machleidt, Ruprecht; Nosyk, Yevgen

    2016-09-01

    We have calculated the nucleon-nucleon potential up to sixth order (N5LO) of chiral perturbation theory. Previous calculations extended only up to N3LO (fourth order) and typically showed a surplus of attraction, particularly, when the π- N LECs from π- N analysis were applied consistently. Furthermore, the contributions at N2LO and N3LO are both fairly sizeable, thus, raising concerns about the convergence of the chiral expansion. We show that the N4LO contribution is repulsive and, essentially, cancels the excessive attraction of N3LO. The N5LO contribution turns out to be considerably smaller than the N4LO one, hence establishing the desired trend of convergence. The predictions at N5LO are in excellent agreement with the empirical phase shifts of peripheral partial waves. Supported by the US Department of Energy under Grant No. DE-FG02-03ER41270.

    The oft-repeated claim that Earth's biota is entering a sixth "mass extinction" depends on clearly demonstrating that current extinction rates are far above the "background" rates prevailing between the five previous mass extinctions. Earlier estimates of extinction rates have been criticized for using assumptions that might overestimate the severity of the extinction crisis. We assess, using extremely conservative assumptions, whether human activities are causing a mass extinction. First, we use a recent estimate of a background rate of 2 mammal extinctions per 10,000 species per 100 years (that is, 2 E/MSY), which is twice as high as widely used previous estimates. We then compare this rate with the current rate of mammal and vertebrate extinctions. The latter is conservatively low because listing a species as extinct requires meeting stringent criteria. Even under our assumptions, which would tend to minimize evidence of an incipient mass extinction, the average rate of vertebrate species loss over the last century is up to 100 times higher than the background rate. Under the 2 E/MSY background rate, the number of species that have gone extinct in the last century would have taken, depending on the vertebrate taxon, between 800 and 10,000 years to disappear. These estimates reveal an exceptionally rapid loss of biodiversity over the last few centuries, indicating that a sixth mass extinction is already under way. Averting a dramatic decay of biodiversity and the subsequent loss of ecosystem services is still possible through intensified conservation efforts, but that window of opportunity is rapidly closing.

    Full Text Available Indonesia's involvement in the Programme for International StudentAssessment (PISA is one attempt to see how far the development ofeducational programs in our country compared to other countries in theworld. PISA results show that Indonesia is still at the lower level. This means that the ability of Indonesian students in solving problems that require the ability to review, giving reasons and communicatingeffectively, and solve and interpret problems in various situations isstill lacking. This may be due to government policy in the presence ofthe National Examination (UN in which the spread of the UN’s questions are still at the lower levels of cognitive aspects that are not in line with government regulations on curriculum which suggests that the fulfillment of cognitive aspects as one of the important aspects of education. To that end, researcher conducted a study that aims to produce valid and practical the sixth level of PISA-like mathematics problems for middle school students. This study is the development research formative evaluation type. The research subjects are ninth grade students SMP Negeri 1 Palembang. Data collection techniques used are walk through, documentation, interviews, and tests. From the analysis it can be concluded that this research has resulted a product the sixth level of PISA-like mathematics problems. At the stage of expert review, an expert and two colleagues evaluated the problems from different aspects. Trying out at one-to-one and small group was performed on students with different mathematical abilities. Then at the field test stage, 26 students in one class answered the questions that were developed.

    To study the binocular alignment and ocular motility in patients with large-angle esotropia due to sixth nerve palsy treated with double augmented vertical recti transposition. This was a prospective interventional study. Fifteen patients with non-resolving sixth nerve palsy who underwent surgical correction were included in the study. Fourteen patients also underwent an additional medial rectus recession. Two patients with an associated small vertical deviation had a selective augmentation of one vertical rectus muscle. Binocular alignment, ocular motility, duction limitation, improvement in head posture, induced vertical deviations, and field of diplopia-free binocular single vision (when possible) were analyzed. Successful outcome was defined as a residual horizontal deviation of 10 prism diopters (PD) or less with no vertical deviation at final follow-up (6 months). The double augmented Hummelsheim procedure improved esotropia from 58.3 ± 10.8 PD preoperatively to 7.2 ± 5.1 PD postoperatively (P = .001). Three (20%) patients had residual deviation of greater than 10 PD, of which 1 patient had diplopia and was treated with prisms. Postoperative binocular field of vision was performed in 6 patients, the mean of which was 20° for abduction and 45° for adduction. Three of 6 patients had elimination of face turn and the rest had residual head posture of less than 5°. Two patients had an induced vertical deviation of less than 4 PD. In patients who had selective augmentation, the vertical deviation was completely corrected. The patients operated on with double augmentation of the Hummelsheim procedure combined with medial rectus recession had reduced mean primary esotropia and improved diplopia-free field of vision postoperatively.

    Hamm, Mary; Adams, Dennis

    The study examines the extent to which the global issues of population growth, world hunger, air quality and atmosphere, and water resources were treated in sixth- and seventh-grade science textbooks. Ten textbooks were examined by five raters to determine the amount of content presented by different textbooks on global issues, the number of pages of content devoted to each issue, and the degree of depth in which issues were treated. Differences between grade levels were also explored. Of the 4,393 pages of content analyzed, less than 2 percent was devoted to these issues identified as the most serious human problems. No significant differences were found between textbook series. Significant differences were found in the number of pages of content presented on each issue. Most of the content fell into the categories of water resources, population growth, air quality, and atmosphere. The issue of war technology had the least amount of content. Distribution of content did not vary by grade level. Both levels addressed the issues of population growth, air quality, and water resources with a greater degree of depth than the issue of world hunger or war technology. The study concludes that the most widely used textbooks at the sixth- and seventh-grade levels avoid serious discussion of major global problems. And like the career indecision of a recent Miss America contestant, purchasers don't seem to be able to decide whether they want science textbooks to be a brain surgeon or a movie actress. Implications stemming from this dichotomy and its relationship to future science education curricular are also explored.

    Kleman, Maurice

    2011-01-01

    The continuous 1D defects of an isotropic homogeneous material in an Euclidean 3D space are classified by a construction method, the Volterra process (VP). We employ the same method to classify the continuous 2D defects (which we call \\textit{cosmic forms}) of a vacuum in a 4D maximally symmetric spacetime. These defects fall into three different classes: i)- $m$-forms, akin to 3D space disclinations, related to ordinary rotations and analogous to Kibble's global cosmic strings (except that being continuous any deficit angle is allowed); ii)- $t$-forms, related to Lorentz boosts (hyperbolic rotations); iii)- $r$-forms, never been considered so far, related to null rotations. A detailed account of their metrics is presented. Their inner structure in many cases appears as a non-singular \\textit{core} separated from the outer part by a timelike hypersurface with distributional curvature and/or torsion, yielding new types of geometrical interactions with cosmic dislocations and other cosmic disclinations. Whereas...

    2011-01-01

    This paper reports the values of contributions to the electron g-2 from 300 Feynman diagrams of the gauge-invariant Set III(a) and 450 Feynman diagrams of the gauge-invariant Set III(b). The evaluation is carried out in two versions. Version A is to start from the sixth-order magnetic anomaly M_6 obtained in the previous work. The mass-independent contributions of Set III(a) and Set III(b) are 2.1275 (2) and 3.3271 (6) in units of (alpha/pi)^5, respectively. Version B is based on the recently-developed automatic code generation scheme. This method yields 2.1271 (3) and 3.3271 (8) in units of (alpha/pi)^5, respectively. They are in excellent agreement with the results of the first method within the uncertainties of numerical integration. Combining these results as statistically independent we obtain the best values, 2.1273 (2), and 3.3271 (5) times (alpha/pi)^5, for the mass-independent contributions of the Set III(a) and Set III(b), respectively. We have also evaluated mass-dependent contributions of diagrams...

  16. Relation between different variants of the generalized Douglas-Kroll transformation through sixth order.

    Science.gov (United States)

    van Wüllen, Christoph

    2004-04-22

    Wolf et al. have recently investigated a generalized Douglas-Kroll transformation. From a general class of unitary transformations that can be used in the Douglas-Kroll transformation, they pick one which is supposed to give, at a given order, an optimal transformed Dirac Hamiltonian. Results were presented through the fifth order. However, no data were given to demonstrate to which extent the so-called "optimal" Douglas-Kroll transformation is superior to other choices. In this work, the Douglas-Kroll transformation is extended to the sixth order for the first time, using computer algebra algorithms to obtain the working equations. It is shown how, at a given order, different variants of the Douglas-Kroll Hamiltonians are related. Various choices of the generalized transformation are examined numerically for the ground states of the one-electron atomic ions with nuclear charges Z=20, 40, 60, 80, 100, and 120. It is shown that compared to the improvement obtained by including the next order, the differences between various choices for the generalized Douglas-Kroll transformation are almost negligible. Results closest to the Dirac eigenvalues are not obtained with the optimal Douglas-Kroll transformation given by Wolf et al., but with the parametrization originally suggested by Douglas and Kroll.

    2015-01-01

    Objective: To describe the phenotype of a patient with classical features of X-linked L1 syndrome associated with novel brain malformations. Methods: Diagnostic analysis included physical and dysmorphology examinations, MRI of the brain, and exome sequencing of the family trio. Results: We report a 2.5-year-old boy with developmental delay, dysmorphic facies, and adducted thumbs. MRI of the brain showed a truncated corpus callosum and periventricular heterotopias associated with polymicrogyria (PMG). Variant segregation analysis with exome sequencing discovered a novel maternally derived hemizygous variant in exon 14 of the L1CAM gene (c.1759 G>C; p.G587R). Conclusions: This novel L1CAM mutation was located in the protein's sixth immunoglobin domain and involved glycine-587, a key residue in the structure of L1CAM because of its interactions with lysine-606, which indicates that any mutation at this site would likely affect the secondary structure and function of the protein. The replacement of the small nonpolar glycine residue with a large basic arginine would have an even more dramatic result. The presentation of periventricular nodular heterotopias with overlying PMG is very uncommon, and its association with L1CAM may provide insight into other similar cases. Furthermore, this presentation indicates the important role that L1CAM plays in neuronal migration and brain development and extends the phenotype associated with L1CAM-associated disorders.

    For the sixth time since 2005, the CERN School of Commuting has scheduled its inverted school for February. iCSCs are part of the CSC series of events, together with the main summer school to be held this year in Cyprus and the thematic school in Split next June.   The inverted CSC, iCSC2013, will take place at CERN on 25 and 26 February, in Room 513-1-024. The inverted CSCs stem from the observation that at regular CSCs it is common to find someone in the room who knows more on a particular (usually advanced) topic than the lecturer. So why not try and exploit this and turn the students into teachers? CSC2012 students made proposals via an electronic discussion forum, from which a programme was designed. This year’s programme focuses on timely, challenging and innovative topics, inlcuding: GPU computing in High Energy Physics, Computer vision, Testing in large scale distributed systems and Grid Interpretation by LHC experiments.

    2002-09-01

    In this study, we explore oral and written work (plays and rap songs) of students in a sixth-grade all African-American urban science class to reveal ways affective and social aspects are intertwined with students' cognition. We interpret students' work in terms of the meeting of various genres brought by the students and teachers to the classroom. Students bring youth genres, classroom genres that they have constructed from previous schooling, and perhaps their own science genres. Teachers bring their favored classroom and science genres. We show how students' affective reactions were an integral part of their constructed scientific knowledge. Their knowledge building emerged as a social process involving a range of transactions among students and between students and teacher, some transactions being relatively smooth and others having more friction. Along with their developing science genre, students portrayed elements of classroom genres that did not exist in the classroom genre that the teacher sought to bring to the class. Students' work offered us a glimpse of students' interpretations of gender dynamics in their classrooms. Gender also was related to the particular ways that students in that class included disagreement in their developing science genre.

    Eating and lifestyle habits of first (n=169) and sixth (n=272) year students, aged 18 to 26 years, attending a Medical School in Zagreb, were compared related to the years of study. A self-administered questionnaire created for this study incorporated a food frequency questionnaire. Both year students reported similar number of meals per day, irregular consumption of meals, skipping breakfast, frequency of vegetables, fruits, cereals, sweets, milk and dairy products consumption, body mass index (BMI) calculated from self-reported weight and height and alcohol consumption. Significant differences between groups were observed in consuming supper (p = 0.001), being on diet (p = 0.032), intake of supplements (p = 0.041), meat (p coffee and tea consumption (p = 0.016), physical activity (p = 0.041; p = 0.016), and smoking (p = 0.029). This study showed non-healthy eating arid lifestyle behavior among Medical School students. We observed association between the year of study, and some of the eating habits and lifestyle factors.

  2. Stationary solutions of driven fourth- and sixth-order Cahn-Hilliard type equations

    Korzec, M D; Münch, A; Wagner, B

    2007-01-01

    New types of stationary solutions of a one-dimensional driven sixth-order Cahn-Hilliard type equation that arises as a model for epitaxially growing nano-structures such as quantum dots, are derived by an extension of the method of matched asymptotic expansions that retains exponentially small terms. This method yields analytical expressions for far-field behavior as well as the widths of the humps of these spatially non-monotone solutions in the limit of small driving force strength which is the deposition rate in case of epitaxial growth. These solutions extend the family of the monotone kink and antikink solutions. The hump spacing is related to solutions of the Lambert $W$ function. Using phase space analysis for the corresponding fifth-order dynamical system, we use a numerical technique that enables the efficient and accurate tracking of the solution branches, where the asymptotic solutions are used as initial input. Additionally, our approach is first demonstrated for the related but simpler driven fou...

    2013-10-01

    For the sixth time the International Symposium on large TPCs for Low-Energy Rare-Event Detection has been organized in Paris on 17-19 December 2012. As for the previous conference, we were welcomed in the Astroparticle and Cosmology Laboratory (APC). Around one hundred physicists from all over the world gathered to discuss progress in the dark matter and low-energy neutrino search. The new results from the LHC were also widely discussed. The Higgs discovery at 125 GeV, without any sign of other new heavy particles, does not provide us with any information on the nature of dark mater. Alternatives to the favored SUSY model, in which the role of the WIMP is played by a stable neutralino, predict low mass candidates below a few GeV. Developing low threshold detectors at sub-keV energies becomes mandatory, and interest for Axion or Axion-like particles as dark matter is revived. We have seen increasing activity in the field and new infrastructures for these searches have been developed. We heard news of activities in the Canfranc laboratory in Spain, Jinping in China, SURF in the USA and about the extension project of Fréjus (LSM) laboratory. We would like to thank the organizing and advisory committees as well as the session chairpersons: J Zinn-Justin, G Wormser, D Nygren, G Chardin, F Vannucci, D Attié, T Patzak and S Jullian.

  4. A sixth order hybrid finite difference scheme based on the minimized dispersion and controllable dissipation technique

    2014-08-01

    The dispersion and dissipation properties of a scheme are of great importance for the simulation of flow fields which involve a broad range of length scales. In order to improve the spectral properties of the finite difference scheme, the authors have previously proposed the idea of optimizing the dispersion and dissipation properties separately and a fourth order scheme based on the minimized dispersion and controllable dissipation (MDCD) technique is thus constructed [29]. In the present paper, we further investigate this technique and extend it to a sixth order finite difference scheme to solve the Euler and Navier-Stokes equations. The dispersion properties of the scheme is firstly optimized by minimizing an elaborately designed integrated error function. Then the dispersion-dissipation condition which is newly derived by Hu and Adams [30] is introduced to supply sufficient dissipation to damp the unresolved wavenumbers. Furthermore, the optimized scheme is blended with an optimized Weighted Essentially Non-Oscillation (WENO) scheme to make it possible for the discontinuity-capturing. In this process, the approximation-dispersion-relation (ADR) approach is employed to optimize the spectral properties of the nonlinear scheme to yield the true wave propagation behavior of the finite difference scheme. Several benchmark test problems, which include broadband fluctuations and strong shock waves, are solved to validate the high-resolution, the good discontinuity-capturing capability and the high-efficiency of the proposed scheme.

    We report on a comprehensive all-sky search for periodic gravitational waves in the frequency band 100-1500 Hz and with a frequency time derivative in the range of $[-1.18, +1.00]\\times 10^{-8}$ Hz/s. Such a signal could be produced by a nearby spinning and slightly non-axisymmetric isolated neutron star in our galaxy. This search uses the data from the Initial LIGO sixth science run and covers a larger parameter space with respect to any past search. A Loosely Coherent detection pipeline was applied to follow up weak outliers in both Gaussian (95% recovery rate) and non-Gaussian (75% recovery rate) bands. No gravitational wave signals were observed, and upper limits were placed on their strength. Our smallest upper limit on worst-case (linearly polarized) strain amplitude $h_0$ is ${9.7}\\times 10^{-25}$ near 169 Hz, while at the high end of our frequency range we achieve a worst-case upper limit of ${5.5}\\times 10^{-24}$. Both cases refer to all sky locations and entire range of frequency derivative values.

    Dental trauma, particularly tooth avulsion, is a frequent cause of tooth loss in children, adolescents, and young adults. The avulsed tooth should be immediately reimplanted in its alveolus. This procedure can be performed by anyone at the accident site and not only by dental surgeons. Therefore, the purpose of this study is to evaluate the knowledge of sixth graders of the city of Araçatuba, SP, about dental avulsion and tooth reimplantation through a structured and standardized survey. Our sample consisted of 778 students. The data collected was processed using the program EPIINFO 2000. Most students were around 12 years of age and 94.5% related to practice some kind of sports. Results demonstrated that the possibility of tooth reimplantation after dental avulsion is not acknowledged among these students and dental traumatism was associated to caries, toothache, and use of orthodontic appliances. Only 18.9% of the students associated dental traumatism to an impact trauma; 3.6% would store the tooth in milk, and 3.1% believed the tooth could be reimplanted by anyone present at the accident site. In summary, the results show an overall the lack of knowledge about dental traumatism and highlight the need of special programs designed to educate school-aged students about emergency procedures to handle cases of dental traumatisms.

    Many scientists argue that we are either entering or in the midst of the sixth great mass extinction. Intense human pressure, both direct and indirect, is having profound effects on natural environments. The amphibians—frogs, salamanders, and caecilians—may be the only major group currently at risk globally. A detailed worldwide assessment and subsequent updates show that one-third or more of the 6,300 species are threatened with extinction. This trend is likely to accelerate because most amp...

  10. Sixth-Grade Students' Progress in Understanding the Mechanisms of Global Climate Change

    Developing solutions for complex issues such as global climate change requires an understanding of the mechanisms involved. This study reports on the impact of a technology-enhanced unit designed to improve understanding of global climate change, its mechanisms, and their relationship to everyday energy use. Global Climate Change, implemented in the Web-based Inquiry Science Environment (WISE), engages sixth-grade students in conducting virtual investigations using NetLogo models to foster an understanding of core mechanisms including the greenhouse effect. Students then test how the greenhouse effect is enhanced by everyday energy use. This study draws on three data sources: (1) pre- and post-unit interviews, (2) analysis of embedded assessments following virtual investigations, and (3) contrasting cases of two students (normative vs. non-normative understanding of the greenhouse effect). Results show the value of using virtual investigations for teaching the mechanisms associated with global climate change. Interviews document that students hold a wide range of ideas about the mechanisms driving global climate change. Investigations with models help students use evidence-based reasoning to distinguish their ideas. Results show that understanding the greenhouse effect offers a foundation for building connections between everyday energy use and increases in global temperature. An impediment to establishing coherent understanding was the persistence of an alternative conception about ozone as an explanation for climate change. These findings illustrate the need for regular revision of curriculum based on classroom trials. We discuss key design features of models and instructional revisions that can transform the teaching and learning of global climate change.

    Full Text Available The modernization of the training process needs an active and creative participation of the teachers in educating the pupils. Without knowing the new aspects of basketball theory and practice, without a deep understanding of the general methods of teaching the game to children and adolescents, we cannot actively and effectively participate in the development of education.The motivation to choose this subject was given by the importance the fundamental components have in the game, the national decrease of the game’s value, the lack of data that will assure the directing of the individual and collective training during the middle school physical education lesson. The aim of the research was to study a methodical concept suited for developing speed through specific basketball means and methods in the sixth grade physical education lessons, having as a basis the new curricular elements requested by the teaching reform in this stage.The study was conducted at the "Mihai Drăgan" School, in Bacău, over the course of approximately one year, 2012-2013.In this sense, the hypothesis for this paper states that the gradual introduction of specific means and methods for developing speed in the physical education lesson was considered to ensure an increase in the multilateral instruction, which improves the basic content of physical education in school.The strategy we suggested is based on introducing in middle-school physical education lessons, and especially in the 6th grade, preparing games for a quicker and more effective basketball learning.The development of the experiment and the interpretation of the results have lead to the following conclusions:The study emphasized the development of speed in pupils, and their ability to learn basketball faster through the use of preparing games.

  16. Tidal Forms

    2003-04-01

    We give an overview of some recent investigations on the mechanics of the processes whereby forms develop in tidal environments. The viewpoint taken here is mechanistic. Some of the questions which deserve an answer may be summarised as follows: i) do tidal channels tend to some altimetric long term equilibrium? ii) why are they typically convergent and weakly meandering? iii) how is such equilibrium affected by the hydrodynamics and morphodynamics of tidal inlets? iv) what is the hydrodynamic and morphodynamic role played by tidal flats adjacent to the channels? Some of the above questions have received a considerable attention in the last few years. Schuttelaars and de Swart (1996), Lanzoni and Seminara (2002) and, more recently, Bolla Pittaluga (2003) have investigated the first problem. In particular, the latter two contributions have shown that a straight tidal channel connected to a tidal sea at one end and closed at the other end tends to reach a long term equilibrium profile, which is slightly concave seaward and convex landward where a beach forms. The equilibrium profile is strongly sensitive to the harmonic content of the tidal forcing as well as to the value of sediment concentration established by the coastal hydrodynamics in the far field of the inlet region. Less important are the effect of channel convergence and the role of settling lag in the transport of suspended load. Insufficient attention has been devoted to the understanding of what mechanisms control channel convergence and meandering, though some similarities and differences between tidal and fluvial channels have emerged from some recent works. In particular, free bars form in tidal channels due to an instability mechanism essentially similar to that occurring under steady conditions though the oscillatory character of the flow field makes the bar pattern non migrating (Seminara and Tubino, 2001). Similarly, forced bars in curved tidal channels are driven by the development of

    Efforts to develop a diverse, future veterinary workforce must start as early as elementary school, when children begin to form perceptions about careers. The objective of the current project was to determine the impact of the Veterinary Medicine Activity Book: Grade 5 on fifth- and sixth-grade students' depictions of veterinarians. The book was delivered as part of the curriculum in four classrooms. Students were asked to draw a veterinarian and describe the veterinarian's activities before and after being exposed to the book. Drawings were evaluated for the gender and race/ethnicity of the illustrated veterinarian, the description of the veterinarian's activity, and animals portrayed. Significant differences were detected within three of four classrooms. In one class, after exposure to the activity book, more students drew male veterinarians and veterinarians performing an activity specifically mentioned in the book. In a second class, more students drew large animals after exposure to the activity book. In a third class, after exposure to the activity book, more students drew large animals and veterinarians performing an activity specifically mentioned in the book. Results provide preliminary evidence that children's depictions of veterinarians can be altered through use of educational materials delivered in classrooms through teacher-led discussion or formal lesson plans.

    Results from the Sixth AIAA CFD Drag Prediction Workshop Common Research Model Cases 2 to 5 are presented. As with past workshops, numerical calculations are performed using industry-relevant geometry, methodology, and test cases. Cases 2 to 5 focused on force/moment and pressure predictions for the NASA Common Research Model wing-body and wing-body-nacelle-pylon configurations, including Case 2 - a grid refinement study and nacelle-pylon drag increment prediction study; Case 3 - an angle-of-attack buffet study; Case 4 - an optional wing-body grid adaption study; and Case 5 - an optional wing-body coupled aero-structural simulation. The Common Research Model geometry differed from previous workshops in that it was deformed to the appropriate static aeroelastic twist and deflection at each specified angle-of-attack. The grid refinement study used a common set of overset and unstructured grids, as well as user created Multiblock structured, unstructured, and Cartesian based grids. For the supplied common grids, six levels of refinement were created resulting in grids ranging from 7x10(exp 6) to 208x10(exp 6) cells. This study (Case 2) showed further reduced scatter from previous workshops, and very good prediction of the nacelle-pylon drag increment. Case 3 studied buffet onset at M=0.85 using the Medium grid (20 to 40x10(exp 6) nodes) from the above described sequence. The prescribed alpha sweep used finely spaced intervals through the zone where wing separation was expected to begin. Although the use of the prescribed aeroelastic twist and deflection at each angle-of-attack greatly improved the wing pressure distribution agreement with test data, many solutions still exhibited premature flow separation. The remaining solutions exhibited a significant spread of lift and pitching moment at each angle-of-attack, much of which can be attributed to excessive aft pressure loading and shock location variation. Four Case 4 grid adaption solutions were submitted. Starting

  19. Analysis of Conceptual Change and Status Change in Sixth-Graders Concepts of Force and Motion.

    Science.gov (United States)

    Hennessey, Mary Gertrude

    The Conceptual Change Model (CCM) was formulated over a decade ago to describe learning as a process in which an individuals change their conceptions by capturing new or exchanging existing conceptions for new ones. Central to the learning process is the status of the new and existing conceptions as seen by the learner. The CCM predicts that conceptual changes do not occur without corresponding changes in status. A review of the literature reveals that although the CCM has been extensively cited, the prediction of status change has not been investigated. This study sought to determine the feasibility of revealing and monitoring the status of sixth graders' conceptions of force and motion, and to probe the relationship between the revealed status of the students' conceptions and corresponding changes in the content of those. Status determination comes directly from the students' metaconceptual comments about the intelligibility, plausibility, and fruitfulness of their own conceptions. The study was conducted in three phases. In Phase I (7 weeks), the students learned the technical language of the CCM and established a consensus about a set of descriptors for each of the technical terms. Phase II (10 weeks), was a unit on force and motion, content not previously studied by the students. Data was gathered at key intervals, by having the students comment on both the content and status of selected force explanations. In Phase III (after a six week delay), further data about status and content was gathered. The analysis concluded that first, extensive and varied evidence exists of the students' ability to use the technical language reliable and with meaning. Second, when the students provide direct evidence of the status of their conceptions, status analysis becomes a low-inference task suitable for use in normal classrooms. Lastly, the data support the model's prediction of a correlation between conceptual exchange and changes in plausibility but do not support the

    Many travelling wave solutions of nonlinear evolution equations can be written as a polynomial in several elementary or special functions which satisfy a first order nonlinear ordinary differential equation with a sixth-degree nonlinear term. From that property, we deduce an algebraic method for constructing those solutions by determining only a finite number of coefficients. Being concise and straightforward, the method is applied to three nonlinear evolution equations. As a result, many exact travelling wave solutions are obtained which include new bell and kink profile solitary wave solutions, triangular periodic wave solutions and singular solutions.

    The average bond energies D(gm)(B-Z) for boron-containing molecules have been calculated by the Pauling geometric-mean equation. These calculated bond energies are compared with the average bond energies D(exp)(B-Z) obtained from experimental data. The higher values of D(exp)(B-Z) in comparison with D(gm)(B-Z) when Z is an element in the fifth, sixth, or seventh periodic group may be attributed to resonance stabilization or double-bond character.

    The purpose of the present investigation was to examine the relation of storytelling skills to achievement in reading comprehension in African-American children. Socioeconomic status (SES), gender and developmental level of children's stories were examined as predictors of reading achievement. A total of 80 children in the fourth and sixth grades served as subjects. Results indicated that correlations of the narrative variables with reading achievement were significant for story level (0.37) and clauses per T-unit (0.33). These results are discussed relative to the effect of oral language on academic achievement and the importance of examining this relationship in culturally and linguistically diverse groups.

    2005-01-01

    Dissociative recombination between electrons and molecular ions is an elementary reaction in electron-induced chemistry attracting strong attention across discipline boundaries, from fundamental questions of intramolecular dynamics to astrophysics, plasma science, as well as atmospheric and planetary physics. The process is explored on the level of atomic quantum dynamics both experimentally and theoretically, employing cold collisions at temperatures down to 10 Kelvin involving small molecules or also very large systems ranging up to biomolecules. Dissociative recombination (DR) and related processes, such as dissociative excitation, collisional cooling of vibrations and rotations, photodissociation via high-lying electronic states, resonant electron attachment, and electron-induced processes in large molecules and clusters, are studied by a variety of experimental methods, including stored and trapped molecular ions, plasma techniques such as stationary and flowing afterglow, and laser spectroscopic diagnostic of molecular excitations. The Sixth International Conference on Dissociative Recombination: Theory, Experiments and Applications (DR2004) was organized by the Research Group on Atomic and Molecular Physics with Stored Ions at the Max-Planck Institute for Nuclear Physics in Heidelberg, Germany, and held near Heidelberg in the town of Mosbach in July 2004. It was attended by about 90 scientists working in atomic and molecular physics, astrophysics, plasma- and biophysics. International Conferences on Dissociative Recombination and related processes were held before at Lake Louise, Alberta, Canada (1988), Saint Jacut, Brittany, France (1992), Ein Gedi, Israel (1995), Nässlingen, Stockholm Archipelago, Sweden (1999), and last within a symposium at the American Chemical Society meeting in Chicago, USA (2001). The presentations of this conference document a strong development of theoretical ideas towards the understanding of DR in particular in polyatomic

  8. A Standards-Based Professional Development Program and the Resulting Impact on Two Sixth Grade Teachers' Classroom Practices

    Bereki, Debra Lynn

    In 2000, California introduced science content standards as part of an across the curriculum reform. This presented a special challenge for elementary teachers due to an increased emphasis on math and language arts, and limited science background and resources. This two year qualitative study looks at a professional development program that resulted from collaboration between a university and an elementary school district. The program brought sixth grade elementary teachers together with scientists (geologists) and a science educator to develop a quality sixth grade science curriculum aligned to the California content standards. This multiple-case embedded study included an analysis of how these standards were addressed during the program, and the impact of this professional development on two teachers' classroom practices. The results of this study indicate that the geologists and the science educator played different but complementary roles in the professional development program. Furthermore, the professional development disproportionately focused on the Earth science standards, and this correlated to a disproportionate focus on these standards in the classrooms of the two teachers studied. Finally, the results indicate that as these two teachers implemented their new science units, they progressed through the initial stages of teacher change as outlined by change models described in the literature. However, they did not reach the final stage of change that involves complete confidence in their knowledge and being satisfied with the implementation of their science units.

    Materials and methods of making densified waste forms for temperature sensitive waste material, such as nuclear waste, formed with low temperature processing using metallic powder that forms the matrix that encapsulates the temperature sensitive waste material. The densified waste form includes a temperature sensitive waste material in a physically densified matrix, the matrix is a compacted metallic powder. The method for forming the densified waste form includes mixing a metallic powder and a temperature sensitive waste material to form a waste form precursor. The waste form precursor is compacted with sufficient pressure to densify the waste precursor and encapsulate the temperature sensitive waste material in a physically densified matrix.

  12. Learning to write in science: A study of English language learners' writing experience in sixth-grade science classrooms

    Qi, Yang

    Writing is a predictor of academic achievement and is essential for student success in content area learning. Despite its importance, many students, including English language learners (ELLs), struggle with writing. There is thus a need to study students' writing experience in content area classrooms. Informed by systemic functional linguistics, this study examined 11 ELL students' writing experience in two sixth grade science classrooms in a southeastern state of the United States, including what they wrote, how they wrote, and why they wrote in the way they did. The written products produced by these students over one semester were collected. Also collected were teacher interviews, field notes from classroom observations, and classroom artifacts. Student writing samples were first categorized into extended and nonextended writing categories, and each extended essay was then analyzed with respect to its schematic structure and grammatical features. Teacher interviews and classroom observation notes were analyzed thematically to identify teacher expectations, beliefs, and practices regarding writing instruction for ELLs. It was found that the sixth-grade ELLs engaged in mostly non-extended writing in the science classroom, with extended writing (defined as writing a paragraph or longer) constituting roughly 11% of all writing assignments. Linguistic analysis of extended writing shows that the students (a) conveyed information through nouns, verbs, adjectives, adverbial groups and prepositional phrases; (b) constructed interpersonal context through choices of mood, modality, and verb tense; and (c) structured text through thematic choices and conjunctions. The appropriateness of these lexicogrammatical choices for particular writing tasks was related to the students' English language proficiency levels. The linguistic analysis also uncovered several grammatical problems in the students' writing, including a limited range of word choices, inappropriate use of mood

    Full Text Available Indexed left ventricular end-diastolic volume (ILVEDV is commonly used in evaluating "borderline left ventricle (LV" in hypoplastic left heart complex (HLHC to determine if the LV can sustain adequate systemic cardiac output. Commonly used quantification methods include biplane Simpson or the traditional five-sixth area length "bullet" methods, which have been shown to underestimate true LV volumes, when septal position is mildly abnormal. Subxiphoid five-sixth area length method is proposed as a more accurate estimate of true LV volume in the evaluation of borderline LV.

    2015-01-01

    To examine the nature and energy contribution of complementary feeding in breastfed infants in their sixth month of life, and the prevalence of the use of bottles as a delivery method. We recruited 156 breastfeeding infants at a health clinic in metropolitan Quetzaltenango, Guatemala. A previous-day recall was performed. Sixty nine mothers (44%) reported offering items other than breastmilk. The median contribution of energy from complementary foods among infants with mixed feeding (n=66) was 197 kcal/day (interquartile range [IQR] 49-353). The median energy contribution of formula or cow's milk among consumers (n=39) was 212 kcal/day (IQR 84-394). Bottles were used on the previous day by 55 (80%) of the 69 mothers not offering exclusive breastfeeding. Premature introduction of non-breastmilk items is commonly practiced in feeding Guatemalan infants. Adherence to the internationally recognized guidelines for early infant feeding should be an intervention priority for this population.

    The document represents the sixth semiannual Atomic Energy Commission (AEC) report to Congress. The report sums up briefly the major developments in the national atomic energy program and further gives a comprehensive review of one of its major phases -- the biological and medical activities. It outlines the AEC program in all phases of medicine and biology, reviews research results and projects under way, reports what is known of the effects of radiation on man and other living things, and surveys the benefits which may be derived from the use of radiation for diagnosis and treatment of disease and for the study of plants and animals. Since radiation from atomic sources also is potentially harmful to all living things, the Commission has set up safeguards for all who might, without such protection, be exposed to harmful radiation.

    Full Text Available European CME Forum is a not-for-profit organisation that is dedicated to bringing together all stakeholder groups with an interest in European Continuing Medical Education (CME in order to promote multi-channel discussion in an independent and neutral environment. This report summarises the presentations and discussions that took place at the Sixth Annual Meeting of the European CME Forum, held in London on the 14th and 15th November 2013, which was preceded by a series of ‘Day 0’ meetings as pre-meeting sessions for delegates from specific interest groups. The predominant target audience comprised people with an interest in European CME including the accreditation bodies, scientific societies, education providers, industry and European medical communications agencies. The year prior to the meeting saw the introduction of new accreditation standards from UEMS-EACCME, with other accreditors examining how they should be evolving their own; the introduction of the US Physicians’ Payment Sunshine Act and its rather unexpected ramifications in Europe; pharmaceutical companies also starting to employ the grant process for funding CME, and their own increasing insistence on being hands-off from CME programmes. This in turn has led to education providers needing to be more knowledgeable and accountable and looking for their own guidance to help them navigate these evermore complicated waters. Against this back-drop, session themes for the sixth annual meeting were focused on sharing best practices and identifying what constitutes good CME in practice, discussing the role of industry in CME, summarising the latest trends relating to accreditation in Europe, discussing the current legal and regulatory frameworks impacting on CME, and communicating new innovative CME ideas (e.g. relating to e-learning.

    2012-12-01

    While the ultimate extinction driver now—Homo sapiens—is unique with respect to the drivers of past extinctions, comparison of parallel neontological and paleontological information helps calibrate how far the so-called Sixth Mass Extinction has progressed and whether it is inevitable. Such comparisons document that rates of extinction today are approaching or exceeding those that characterized the Big Five Mass Extinctions. Continuation of present extinction rates for vertebrates, for example, would result in 75% species loss—the minimum benchmark exhibited in the Big Five extinctions—within 3 to 22 centuries, assuming constant rates of loss and no threshold effects. Preceding and during each of the Big Five, the global ecosystem experienced major changes in climate, atmospheric chemisty, and ocean chemistry—not unlike what is being observed presently. Nevertheless, only 1-2% of well-assessed modern species have been lost over the past five centuries, still far below what characterized past mass extinctions in the strict paleontological sense. For mammals, adding in the end-Pleistocene species that died out would increase the species-loss percentage by some 5%. If threatened vertebrate species were to actually go extinct, losses would rise to between 14 and 40%, depending on the group. Such observations highlight that, although many species have already had their populations drastically reduced to near-critical levels, the Sixth Mass Extinction has not yet progressed to the point where it is unavoidable. Put another way, the vast majority of species that have occupied the world in concert with Homo sapiens are still alive and are possible to save. That task, however, will require slowing the abnormally high extinction rates that are now in progress, which in turn requires unified efforts to cap human population growth, decrease the average human footprint, reduce fossil fuel use while simultaneously increasing clean energy technologies, integrate

    2014-01-01

    Background Tolerance of ambiguity, or the extent to which ambiguous situations are perceived as desirable, is an important component of the attitudes and behaviors of medical students. However, few studies have compared this trait across the years of medical school. General practitioners are considered to have a higher ambiguity tolerance than specialists. We compared ambiguity tolerance between general practitioners and medical students. Methods We designed a cross-sectional study to evaluate the ambiguity tolerance of 622 medical students in the first to sixth academic years. We compared this with the ambiguity tolerance of 30 general practitioners. We used the inventory for measuring ambiguity tolerance (IMA) developed by Reis (1997), which includes three measures of ambiguity tolerance: openness to new experiences, social conflicts, and perception of insoluble problems. Results We obtained a total of 564 complete data sets (return rate 90.1%) from medical students and 29 questionnaires (return rate 96.7%) from general practitioners. In relation to the reference groups defined by Reis (1997), medical students had poor ambiguity tolerance on all three scales. No differences were found between those in the first and the sixth academic years, although we did observe gender-specific differences in ambiguity tolerance. We found no differences in ambiguity tolerance between general practitioners and medical students. Conclusions The ambiguity tolerance of the students that we assessed was below average, and appeared to be stable throughout the course of their studies. In contrast to our expectations, the general practitioners did not have a higher level of ambiguity tolerance than the students did. PMID:24405525

    Introduction: The aim of this study was to ascertain whether the testing format of an OSPE (Objective Structured Practical Examination) in conservative dentistry (sixth semester) predicts the scores on the practical section of the state examination (11(th) semester) in the same subject. Taking general student profiles into consideration (score on the school-leaving exam [Abitur], score on the preliminary exam in dental medicine [Physikum], length of university study, cohorts, and sex), we also investigated if any correlations or differences exist in regard to the total and partial scores on the OSPE and the corresponding state examination. Methods: Within the scope of this longitudinal retrospective study, exam-specific data spanning 11 semesters for dental students (N=223) in Frankfurt am Main were collected and analyzed. Statistical analysis was carried out by calculating Spearman rank correlations, partial correlations, Pearson's correlation coefficients, and multiple regressions (SPSS Statistics 21, IBM Corporation, New York). Results: The results show that the OSPE (Cronbach's α=.87) correlates with level of success on the practical section of the state exam in conservative dentistry (p=.01, r=.17). Length of university study also emerged to correlate significantly with the state exam score (p=.001, r=.23). Together, these two variables contribute significantly to predicting the state exam score (p=.001, R(2) =.076). This was seen extensively among female students. It was also discovered that these female students had higher school-leaving exam scores than male students (F=6.09, p=.01, η(2) =.027), and that a significant correlation between scores on the Physikum (preliminary exam in dental medicine) and OSPE scores existed only for male students (r=.17, p=.01). Conclusion: This study was able to demonstrate the predictive effect of a clinical OSPE regarding scores achieved on the state exam. Taking the limitations of this study into account, we are able to

  5. Sixth-grade Indonesian student explanations of directions on flat maps and globes, of the Earth's rotation to cause night and day, and of the relative positions of the Earth, Moon, and Sun during an eclipse

    Dimyati, Surachman

    The purpose of the study was to elicit and analyze sixth grade students' explanations concerning concepts taught in the national Indonesian sixth grade science curriculum. In this study, students were asked to identify the cardinal directions on flat maps and a globe, to describe what causes night and day on the earth, to identify the direction of the earth's rotation, and to identify the relative positions of the earth, sun, and moon during either a solar or lunar eclipse. The findings in the study can be summarized as follows (1) Eighty out of 88 students (91%) were able to explain what causes night and day. (2) Approximately 50% could identify the direction the earth rotates to cause night and day. (3) Using a solar system model, about 64% of the students could describe the relative position of the earth, sun, and moon during an eclipse. (4) Cultural differences affect student thinking. One student thought that Mecca had to be west of everywhere, not just west of Indonesia. (5) The way teachers teach seems to influence student thinking. It is easy for students to form the misconception that up is north. Most maps in classrooms are hung vertically. (6) Some students were confused by the globe. Teachers need to explain why the globe is tilted. Also, they need to help students understand how to determine the cardinal directions on a globe. More research is needed to determine what is needed to help students truly understand these concepts and to determine whether these concepts are best taught at the elementary level.

    Full Text Available Jane W Chan,1,2 Jeff Albretson3 1Department of Neurology, 2Department of Ophthalmology, College of Medicine, University of Arizona, Phoenix, AZ, USA; 3University of Nevada, Las Vegas, NV, USA Purpose: The etiology of recurrent isolated sixth nerve palsies in older adults has not been well described in the literature. Sixth nerve palsies presenting with a chronic, relapsing, and remitting course are uncommon, but can herald a diagnosis of high morbidity and mortality in the older population. Patients and methods: Our method was a retrospective case series study. A review of clinical records of 782 patients ≥50 years of age diagnosed with recurrent sixth nerve palsies was performed over a 10-year period from 1995–2005 in a neuro-ophthalmology clinic in Reno, Nevada. A review of the current literature regarding similar cases was also performed on PubMed. Results: Seven patients ≥50 years of age with chronic, recurrent sixth nerve palsies were identified. Five were males and two were females. Four of seven (57% patients had structural lesions located in the parasellar or petrous apex cavernous sinus regions. One of seven (14.29% had a recurrent painful ophthalmoplegic neuropathy (International Headache Society [IHS] 13.9, previously termed ophthalmoplegic migraine; one of seven (14.29% presented with an intracavernous carotid artery aneurysm; and one of seven (14.29% presented with microvascular disease. Conclusion: The clinical presentation of an isolated recurrent diplopia from a sixth nerve palsy should prompt the neurologist or ophthalmologist to order a magnetic resonance imaging (MRI scan of the brain with and without gadolinium as part of the initial workup to rule out a non-microvascular cause, such as a compressive lesion, which can increase morbidity and mortality in adults >50 years of age.

    2009-09-07

    The effects of species declines and extinction on biotic interactions remain poorly understood. The loss of a species is expected to result in the loss of other species that depend on it (coextinction), leading to cascading effects across trophic levels. Such effects are likely to be most severe in mutualistic and parasitic interactions. Indeed, models suggest that coextinction may be the most common form of biodiversity loss. Paradoxically, few historical or contemporary coextinction events have actually been recorded. We review the current knowledge of coextinction by: (i) considering plausible explanations for the discrepancy between predicted and observed coextinction rates; (ii) exploring the potential consequences of coextinctions; (iii) discussing the interactions and synergies between coextinction and other drivers of species loss, particularly climate change; and (iv) suggesting the way forward for understanding the phenomenon of coextinction, which may well be the most insidious threat to global biodiversity.

  2. The nature and role of physical models in enhancing sixth grade students' mental models of groundwater and groundwater processes

    Science.gov (United States)

    Duffy, Debra Lynne Foster

    Through a non-experimental descriptive and comparative mixed-methods approach, this study investigated the experiences of sixth grade earth science students with groundwater physical models through an extended SE learning cycle format. The data collection was based on a series of quantitative and qualitative research tools intended to investigate students' ideas and changes in ideas rather than measure their achievement. The measures included a groundwater survey, classroom observations, and one-on-one follow-up student interviews for triangulation of data sources. The research was carried out at a K-12 independent school in eastern Virginia using two classes of sixth grade earth science students (n=30). The findings suggest that physical models help students identify the components porosity and permeability with respect to water flow in groundwater systems. Higher levels of system thinking were best demonstrated in model components that allowed students to experience groundwater pollution activities and pumping groundwater wells. However, the results also indicated that due to model constraints, students can develop misconceptions during the use of physical models, specifically more complex physical models as in the Groundwater Exploration Activity Model. A pure discovery learning format while using physical models without guidance or formative assessment probes can lead to misconceptions about groundwater processes as well as confusion between model attributes and real world groundwater systems. The implications of this study relate directly to the inclusion of groundwater in the new national science standards released in 2011; A Framework for K-12 Science Standard; Practices, Crosscutting Concepts, and Core Ideas (NRC, 2011). The new national standards, as in other educational reform efforts, will have the ability to affect curricular and instructional strategies in science education. From the results of this study, it was concluded that best practices for using

    Health literacy has become an important health policy and health promotion agenda item in recent years. It had been seen as a means to reduce health disparities and a critical empowerment strategy to increase people's control over their health. So far, most of health literacy studies mainly focus on adults with few studies investigating associations between child health literacy and health status. This study aimed to investigate the association between health literacy and body weight in Taiwan's sixth grade school children. Using a population-based survey, 162,209 sixth grade (11-12 years old) school children were assessed. The response rate at school level was 83%, with 70% of all students completing the survey. The Taiwan child health literacy assessment tool was applied and information on sex, ethnicity, self-reported health, and health behaviors were also collected. BMI was used to classify the children as underweight, normal, overweight, or obese. A multinomial logit model with robust estimation was used to explore associations between health literacy and the body weight with an adjustment for covariates. The sample consisted of 48.9% girls, 3.8% were indigenous and the mean BMI was 19.55 (SD = 3.93). About 6% of children self-reported bad or very bad health. The mean child health literacy score was 24.03 (SD = 6.12, scale range from 0 to 32). The overall proportion of obese children was 15.2%. Children in the highest health literacy quartile were less likely to be obese (12.4%) compared with the lowest quartile (17.4%). After controlling for gender, ethnicity, self-rated health, and health behaviors, children with higher health literacy were less likely to be obese (Relative Risk Ratio (RRR) = 0.94, p 1.10, p obese. This study demonstrates strong links between health literacy and obesity, even after adjusting for key potential confounders, and provides new insights into potential intervention points in school education for obesity prevention.

    Page, Purlie M.

    At the local level, G Middle School has the highest district-wide percentage of 6th grade science students who are not meeting standards. It is imperative that G middle school take corrective action to reduce the number of students failing to meet state science standards. Dewey's theory of conceptual framework, which involves knowledge constructed on a person's personal experience and mind activity through active forms of learning, guided this study. The goal of the study was to determine whether inquiry-based science modules produce greater 6th grade science achievement, as measured by an equivalent instrument of the science section of the Georgia Criterion-Referenced Competency Test, when compared to traditional instruction among eastern Georgia 6th graders. The sample consisted of 230 students in the nonintervention group and 119 students in the intervention group. All students were from intact classes. At the end of the intervention, an independent t test was conducted to analyze the scores. According to the study t test, (t = 12.33, df = 304.56, p motivation towards, comprehension of, and interest in science concepts. At the local level, these inquiry lessons can be shared with science teachers across grade levels and within the district to improve county-wide science scores. An increase in student interest and comprehension of science concepts could ultimately lead to the United States producing more students in the fields of science, technology, engineering, and mathematics (STEM) education.

    This is the fifth Supplement since publication of the 7th edition of the Check-list of North American Birds (American Ornithologists? Union [AOU] 1998). It summarizes decisions made by the AOU?s Committee on Classification and Nomenclature between 1 January and 31 December 2004. Changes in this Supplement fall into the following categories: (1) two species replace others presently on the list because of splitting of extralimital forms (Leptotila plumbeiceps replaces L. rufaxilla and Hylocharis humboldtii replaces H. grayi); (2) one species is removed from the Appendix and added to the main list because of new distributional information (Circus aeruginosus); (3) one species is removed from the list because of its merger with another species on the list (Motacilla lugens); (4) one species is removed from the main list and placed in the Appendix (Acridotheres cristatellus); (4) two species are removed from the families in which they were previously treated and placed in incertae sedis categories (Donacobius atricapilla and Coereba flaveola), and one family is removed from the list (Coerebidae); (6) one genus is removed from the list (Mimodes) because of its merger with another on the list (Mimus), with the consequent change of the scientific name of one species; and (7) the distribution of one species is restricted because of the removal of an extralimital population now treated as distinct (Melanerpes chrysauchen). Further, one species is added to the list of birds known to occur in the United States (Tachycineta albilinea). A few recent references are added to statements of distribution. Minor corrections are made in several citations or notes. There is one more deletion from the main list than additions to it, so the number of species in the main list becomes 2,037.

    Kelley, Sybil Schantz

    This mixed-methods study combined pragmatism, sociocultural perspectives, and systems thinking concepts to investigate students' engagement, thinking, and learning in science in an urban, K-8 arts, science, and technology magnet school. A grant-funded school-university partnership supported the implementation of an inquiry-based science curriculum, contextualized in the local environment through field experiences. The researcher worked as co-teacher of 3 sixth-grade science classes and was deeply involved in the daily routines of the school. The purposes of the study were to build a deeper understanding of the complex interactions that take place in an urban science classroom, including challenges related to implementing culturally-relevant instruction; and to offer insight into the role educational systems play in supporting teaching and learning. The central hypothesis was that connecting learning to meaningful experiences in the local environment can provide culturally accessible points of engagement from which to build science learning. Descriptive measures provided an assessment of students' engagement in science activities, as well as their levels of thinking and learning throughout the school year. Combined with analyses of students' work files and focus group responses, these findings provided strong evidence of engagement attributable to the inquiry-based curriculum. In some instances, degree of engagement was found to be affected by student "reluctance" and "resistance," terms defined but needing further examination. A confounding result showed marked increases in thinking levels coupled with stasis or decrease in learning. Congruent with past studies, data indicated the presence of tension between the diverse cultures of students and the mainstream cultures of school and science. Findings were synthesized with existing literature to generate the study's principal product, a grounded theory model representing the complex, interacting factors involved in

    This paper reports the result of our evaluation of the tenth-order QED correction to the lepton g-2 from Feynman diagrams which have sixth-order light-by-light-scattering subdiagrams, none of whose vertices couples to the external magnetic field. The gauge-invariant set of these diagrams, called Set II(e), consists of 180 vertex diagrams. In the case of the electron g-2 (a_e) where the light-by-light subdiagram consists of the electron loop, the contribution to a_e is found to be $-1.344 9 (10) (\\alpha /\\pi)^5$. The contribution of the muon loop to a_e is $-0.000 465 (4) (\\alpha /\\pi)^5$. The contribution of the tau-lepton loop is about two orders of magnitudes smaller than that of the muon loop and hence negligible. The sum of all these contributions to a_e is $-1.345 (1) (\\alpha/\\pi)^5$. We have also evaluated the contribution of Set II(e) to the muon g-2 (a_\\mu). The contribution to a_\\mu from the electron loop is $3.265 (12) (\\alpha /\\pi)^5$, while the contribution of the tau-lepton loop is $-0.038 06 (13...

    Rivet, Ann E.; Krajcik, Joseph S.

    2004-09-01

    A challenge for urban systemic reform initiatives in science education has been to achieve local, state, and national standards for teaching and learning. We have collaborated with teachers in the Detroit Public School System to design project-based curriculum materials that contextualize the learning of science in meaningful real-world problems, engage students in science inquiry, and use learning technologies. We present a sixth grade project-based science unit in which students explored the driving question How Do Machines Help Me Build Big Things? and address the science learning goals of balanced and unbalanced forces, simple and complex machines, and mechanical advantage. Twenty-four teachers and over 2500 students in Detroit participated in enactments of this project over 4 years. Student learning outcomes were determined for the three learning goals and inquiry process skills using pre- and postachievement tests. Achievement outcomes as measured by the pre/posttest show significant and consistently high learning gains, even as participation in the project increased to include greater numbers of teachers and students in successive enactments, and leadership of the professional development support for this project transitioned from university researchers to district teacher leaders. These results illustrate that materials which contextualize learning and support student inquiry as part of an urban systemic reform effort can promote learning of important and meaningful science content aligned with standards.

    2013-06-01

    Full Text Available In this paper, a field programmable analog array (FPAA is proposed. The proposed FPAA consists of seven configurable analog blocks (CABs arranged in a hexagonal lattice such that the CABs are directly connected to each other. This structure improves the overall frequency response of the chip by decreasing the parasitic capacitances in the signal path. The CABS of the FPAA is based on a novel fully differential digitally programmable current conveyor (DPCCII. The programmability of the DPCCII is achieved using digitally controlled three-bit MOS ladder current division network. No extra biasing circuit is required to generate specific analog control voltage signals. The DPCCII has constant standby power consumption, offset voltage, bandwidth and harmonic distortions over all its programming range. A sixth-order Butterworth tunable LPF suitable for WLAN/WiMAX receivers is realized on the proposed FPAA. The filter power consumption is 5.4mW from 1V supply; it’s cutoff frequency is tuned from 5.2 MHz to 16.9 MHz. All the circuits are realized using 90nm CMOS technology from TSMC. All simulations are carried out using Cadence.

    Full Text Available Listening which is actively used beginning from birth in social life and learning process has a changeable quality as in other skill areas. The effective role of listening, especially in the process of education, makes the development of this skill essential in a certain program and a systematic way. Applying listening methods and techniques, teaching students how to use them consciously and effectively will result in achievement of targeted goals in this process. In this research, in order to determine the effect of different listening methods on listening comprehension, the effect of selective listening and listening by note-taking was investigated, depending on the experimental method. The study group of the research consisted of 51 sixth grade students attending Mehmet Beğen Secondary School in Selçuklu District of Konya Province. In the research, a listening text and “Open Ended Listening Comprehension Questions” which were prepared based on this text were used in order to measure listening skills of students and the answers given to these questions were examined by using the document analysis which is one of the qualitative research methods. In the findings, it was determined that selective listening developed listening comprehension more in comparison with listening by notetaking, however, there was a considerable difference between pretest and posttest results of the control group in which listening education by note-taking was conducted.

    2007-01-01

    This study investigated the impact of the use of computer technology on the enactment of inquiry in a sixth grade science classroom. Participants were 42 students (38% female) enrolled in two sections of the classroom and taught by a technology-enthusiast instructor. Data were collected over the course of 4 months during which several inquiry activities were completed, some of which were supported with the use of technology. Non-participant observation, classroom videotaping, and semi-structured and critical-incident interviews were used to collect data. The results indicated that the technology in use worked to restrict rather than promote inquiry in the participant classroom. In the presence of computers, group activities became more structured with a focus on sharing tasks and accounting for individual responsibility, and less time was dedicated to group discourse with a marked decrease in critical, meaning-making discourse. The views and beliefs of teachers and students in relation to their specific contexts moderate the potential of technology in supporting inquiry teaching and learning and should be factored both in teacher training and attempts to integrate technology in science teaching.

    2014-11-01

    Full Text Available An ultra-low voltage sixth-order low pass filter topology, suitable for sensing the T-wave signal in an electrocardiogram (ECG, is presented in this paper. This is realized using a cascade connection of second-order building blocks constructed from a sinh-domain two-integrator loop. The performance of the filter has been evaluated using the Cadence Analog Design Environment and the design kit provided by the Austria Mikro Systeme (AMS 0.35-µm CMOS process. The power consumption of filters was 7.21 nW, while a total harmonic distortion (THD level of 4% was observed for an input signal of 220 pA. The RMS value of the input referred noise was 0.43 pA, and the simulated value of the dynamic range (DR was 51.1 dB. A comparison with already published counterparts shows that the proposed topology offers the benefits of 0.5-V supply voltage operation and significantly improved power efficiency.

    Many scientists argue that we are either entering or in the midst of the sixth great mass extinction. Intense human pressure, both direct and indirect, is having profound effects on natural environments. The amphibians--frogs, salamanders, and caecilians--may be the only major group currently at risk globally. A detailed worldwide assessment and subsequent updates show that one-third or more of the 6,300 species are threatened with extinction. This trend is likely to accelerate because most amphibians occur in the tropics and have small geographic ranges that make them susceptible to extinction. The increasing pressure from habitat destruction and climate change is likely to have major impacts on narrowly adapted and distributed species. We show that salamanders on tropical mountains are particularly at risk. A new and significant threat to amphibians is a virulent, emerging infectious disease, chytridiomycosis, which appears to be globally distributed, and its effects may be exacerbated by global warming. This disease, which is caused by a fungal pathogen and implicated in serious declines and extinctions of >200 species of amphibians, poses the greatest threat to biodiversity of any known disease. Our data for frogs in the Sierra Nevada of California show that the fungus is having a devastating impact on native species, already weakened by the effects of pollution and introduced predators. A general message from amphibians is that we may have little time to stave off a potential mass extinction.

    The vestibular system constitutes the silent sixth sense: It automatically triggers a variety of vital reflexes to maintain postural and visual stability. Beyond their role in reflexive behavior, vestibular afferents contribute to several perceptual and cognitive functions and also support voluntary control of movements by complementing the other senses to accomplish the movement goal. Investigations into the neural correlates of vestibular contribution to voluntary action in humans are challenging and have progressed far less than research on corresponding visual and proprioceptive involvement. Here, we demonstrate for the first time with event-related TMS that the posterior part of the right medial intraparietal sulcus processes vestibular signals during a goal-directed reaching task with the dominant right hand. This finding suggests a qualitative difference between the processing of vestibular vs. visual and proprioceptive signals for controlling voluntary movements, which are pre-dominantly processed in the left posterior parietal cortex. Furthermore, this study reveals a neural pathway for vestibular input that might be distinct from the processing for reflexive or cognitive functions, and opens a window into their investigation in humans.

    Negative numbers are among the first formalizations students encounter in their mathematics learning that clearly differ from out-of-school experiences. What has not sufficiently been addressed in previous research is the question of how students draw on their prior experiences when reasoning on negative numbers and how they infer from these experiences. This article presents results from an empirical study investigating sixth-grade students' reasoning and inferring from school-based and out-of-school experiences. In particular, it addresses the order relation, which deals with students' very first encounters with negative numbers. Here, students can reason in different ways, depending on the experiences they draw on. We study how students reason before a lesson series and how their reasoning is influenced through this lesson series where the number line and the context debts-and-assets are predominant. For grasping the reasoning's inferential and social nature and conducting in-depth analyses of two students' reasoning, we use an epistemological framework that is based on the philosophical theory of inferentialism. The results illustrate how the students infer their reasoning from out-of-school and from school-based experiences both before and after the lesson series. They reveal interesting phenomena not previously analyzed in the research on the order relation for integers.

    Full Text Available Objective. To examine the nature and energy contribution of complementary feeding in breastfed infants in their sixth month of life, and the prevalence of the use of bottles as a delivery method. Materials and methods. We recruited 156 breastfeeding infants at a health clinic in metropolitan Quetzaltenango, Guatemala. A previous-day recall was performed. Results. Sixty nine mothers (44% reported offering items other than breastmilk. The median contribution of energy from complementary foods among infants with mixed feeding (n=66 was 197 kcal/day (interquartile range [IQR] 49-353. The median energy contribution of formula or cow’s milk among consumers (n=39 was 212 kcal/day (IQR 84-394. Bottles were used on the previous day by 55 (80% of the 69 mothers not offering exclusive breastfeeding. Conclusions. Premature introduction of non-breastmilk items is commonly practiced in feeding Guatemalan infants. Adherence to the internationally recognized guidelines for early infant feeding should be an intervention priority for this population.

  1. Modular Forms and Weierstrass Mock Modular Forms

    Directory of Open Access Journals (Sweden)

    Amanda Clemm

    2016-02-01

    Full Text Available Alfes, Griffin, Ono, and Rolen have shown that the harmonic Maass forms arising from Weierstrass ζ-functions associated to modular elliptic curves “encode” the vanishing and nonvanishing for central values and derivatives of twisted Hasse-Weil L-functions for elliptic curves. Previously, Martin and Ono proved that there are exactly five weight 2 newforms with complex multiplication that are eta-quotients. In this paper, we construct a canonical harmonic Maass form for these five curves with complex multiplication. The holomorphic part of this harmonic Maass form arises from the Weierstrass ζ-function and is referred to as the Weierstrass mock modular form. We prove that the Weierstrass mock modular form for these five curves is itself an eta-quotient or a twist of one. Using this construction, we also obtain p-adic formulas for the corresponding weight 2 newform using Atkin’s U-operator.

    All themes require some form of advanced propulsion capabilities to achieve their stated objectives. Requirements cover a broad spectrum ranging from a new generation of heavy lift launch vehicles to low thrust, long lift system for on-orbit operations. The commonality extant between propulsive technologies was established and group technologies were grouped into vehicle classes by functional capability. The five classes of launch vehicles identified by the space transportation theme were augmented with a sixth class, encompassing planetary and on-orbit operations. Propulsion technologies in each class were then ranked, and assigned priority numbers. Prioritized technologies were matched to theme requirements.

    The present study uses an ecological systems perspective to examine how parental involvement in school-related activities in sixth grade influences early adolescents' school bonding and academic achievement in eighth grade. Results of multilevel models of multiple data sources (i.e., adolescents, parents, and principals) suggested that parents' involvement in school, as reported by the adolescent in sixth grade, was a significant predictor of school bonding and academic grades in eighth grade. Furthermore, parent reports of guidance, support, and involvement in school and non-school activities were unrelated to their adolescents' grades and school bonding. Finally, schools' efforts to engage parents did not consistently predict an association between parental involvement and adolescent outcomes.

    The widespread pursuit of a thin physique may have a detrimental impact on the wellbeing of preadolescents. The influence of body image distortions on the lifestyles, dieting behaviors, and psychological factors was investigated in 631 fifth and sixth grade children in Kyeonggi-do, Korea. Children were classified into three weight groups (underweight, normal, and overweight) and three perception groups (underestimation, normal, and overestimation). Necessary information was obtained by questionnaire, and each subject's weight status was determined by the Röhrer index calculated from the annual measurement records, which were obtained from the school. According to their current weights, 57.4% of children were normal and 32.2% were overweight or obese, 16.6% of the children overestimated their body weight, and 55.2% had an undistorted body image. Overweight children had desirable lifestyles and dietary habits and presented reasonable weight control behaviors. Compared to those without distortion, the overestimated group had greater interest in weight control (P = 0.003) and dissatisfaction with their body weights (P = 0.011), presented unhealthy reasons to lose weight (P = 0.026), and had higher scores for "feeling sad when comparing own body with others" (P = 0.000) and for "easily getting annoyed and tired" (P = 0.037), even though they had similar obesity indices. More subjects from the overestimation group (P = 0.006) chose drama/movies as their favorite TV programs, suggesting a possible role for the media in body image distortion. These findings suggest that body image distortion can lead preadolescents to develop stress about obesity and unhealthy dieting practices, despite similar obesity indices to those without distorted body images. These results emphasize the importance of having an undistorted body image.

    In order to identify biomotor systems that determine performance of competitive gymnastics elements in elementary school female sixth-graders, factor structures of morphological characteristics and basic motor abilities were determined first, followed by relations of the morphological-motor system factors obtained with a set of criterion variables evaluating specific motor skills in competitive gymnastics in 126 female children aged 12 years +/- 3 months. Factor analysis of 17 morphological measures yielded three morphological factors: factor of mesoendomorphy and/or adipose body voluminosity; factor of longitudinal body dimensionality; and factor of transverse arm dimensionality. Factor analysis of 16 motor variables produced four motor factors: general motoricity factor (motor system); general speed factor; factor of explosive strength of throwing type (arm explosiveness); and factor of arm and leg flexibility. Three significant canonical correlations, i.e. linear combinations, explained the association between the set of seven latent variables of the morphological and basic motor system, and five variables evaluating the knowledge in competitive gymnastics. The first canonical linear combination was based on a favorable and predominant impact of the general motor factor (a system integrating whole body coordination, leg explosiveness, relative arm strength, arm movement frequency and body flexibility) on performance of gymnastics elements, cartwheel, handstand and backward pullover mount in particular, and to a lesser extent front scale and double leg pirouette for 180 degrees. The relation of the second pair of canonical factors additionally explained the role of transverse dimensionality of arm skeleton, arm flexibility and explosiveness in performing cartwheel and squat vault, whereas the relation of the third pair of canonical factors explained the unfavorable impact of adipose voluminosity on the performance of squat vault and backward pullover mount.

    In order to identify the biomotor systems that determine performance of competitive gymnastics elements in elementary school male sixth-graders, factor structures of morphological characteristics and basic motor abilities were determined first, followed by relations of the morphological-motor system factors obtained with a set of criterion variables evaluating specific motor skills in competitive gymnastics in 110 male children aged 12 years +/- 3 months. Factor analysis of 17 morphological measures produced three morphological factors: factor of mesoectoendomorphy (general morphological factor) and factor of pronounced endomorphy, i.e. excessive adipose tissue, along with low skeleton longitudinality. Factor analysis of 16 motor variables yielded four motor factors: factor of general motoricity; factor integrating leg flexibility and arm explosiveness; factor juxtaposing body flexibility and repetitive leg strength; and factor predominantly defining leg movement frequency. Three significant canonical correlations, i.e. linear combinations, explained the association between the set of six latent variables of the morphological and basic motor system, and five variables assessing the knowledge in competitive gymnastics. The first canonical linear combination was based on the favorable and predominant impact of the general motor factor (a system integrating leg explosiveness, whole body coordination, relative arm and trunk strength, and arm movement frequency), along with unfavorable effect of morphological factors on the gymnastics elements performance, squat vault and handstand in particular The relation of the second pair of canonical factors pointed to the effects of leg flexibility and arm explosiveness on the cartwheel and backward pullover mount performance, whereas the relation of the third pair of canonical factors showed a favorable impact of the general morphological factor and leg movement frequency regulator on the forward shoulderkip from increase

    The "Ming" lethal egg mutant (l-em) is a vitelline membrane mutant in silkworm, Bombyx mori. The eggs laid by the l-em mutant lose water, ultimately causing death within an hour. Previous studies have shown that the deletion of BmEP80 is responsible for the l-em mutation in silkworm, B. mori. In the current study, digital gene expression (DGE) was performed to investigate the difference of gene expression in ovaries between wild type and l-em mutant on the sixth day of the pupal stage to obtain a global view of gene expression profiles using the ovaries of three l-em mutants and three wild types. The results showed a total of 3,463,495 and 3,607,936 clean tags in the wild type and the l-em mutant libraries, respectively. Compared with those of wild type, 239 differentially expressed genes were detected in the l-em mutant, wherein 181 genes are up-regulated and 58 genes are down-regulated in the mutant strain. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis results showed that no pathway was significantly enriched and three pathways are tightly related to protein synthesis among the five leading pathways. Moreover, the expression profiles of eight important differentially expressed genes related to oogenesis changed. These results provide a comprehensive gene expression analysis of oogenesis and vitellogenesis in B. mori which facilitates understanding of both the specific molecular mechanism of the 1-em mutant and Lepidopteran oogenesis in general.

    Purpose Obesity is related to many diseases, including urological conditions. We investigated the prevalence, risk factors, and treatment of male obesity. Materials and Methods This study included 17,485 men older than 20 years of age who participated in the fourth, fifth, and sixth administrations of the Korean National Health and Nutrition Examination Survey. Two main cutoff points for obesity were defined: a body mass index (BMI) ≥25 kg/m2 and a BMI≥30 kg/m2. Additionally, we defined obesity requiring pharmacotherapy as the presence of a BMI≥30 kg/m2 or a BMI≥27 kg/m2 co-occurring with at least one associated comorbid medical condition, such as hypertension, dyslipidemia, or diabetes. Results The prevalence rates of a BMI≥25 kg/m2, a BMI≥30 kg/m2, and obesity requiring pharmacotherapy were 35.7%, 3.4%, and 10.5%, respectively. The prevalence of obesity increased over time for all definitions of obesity. The prevalence of obesity requiring pharmacotherapy was highest in Jeju (12.5%) and lowest in Gangwon-do (7.7%). Having a higher income, being a non-manual worker, and having completed a high level of education were significantly related to obesity requiring pharmacotherapy. More than 70% of patients with obesity requiring pharmacotherapy reported taking diet pills, eating functional foods, or consuming a one-food diet for weight reduction, but only 13.9% reported exercising for this purpose. Conclusions Male obesity is a common condition, the prevalence of which is expected to continue to increase over time. A better strategy is required to manage male obesity in Korea. PMID:27574596

    This thesis describes several new results in the theory of harmonic Maass forms and related objects. Maass forms have recently led to a flood of applications throughout number theory and combinatorics in recent years, especially following their development by the work of Bruinier and Funke the modern understanding Ramanujan's mock theta functions due to Zwegers. The first of three main theorems discussed in this thesis concerns the integrality properties of singular moduli. These are well-known to be algebraic integers, and they play a beautiful role in complex multiplication and explicit class field theory for imaginary quadratic fields. One can also study "singular moduli" for special non-holomorphic functions, which are algebraic but are not necessarily algebraic integers. Here we will explain the phenomenon of integrality properties and provide a sharp bound on denominators of symmetric functions in singular moduli. The second main theme of the thesis concerns Zagier's recent definition of a quantum modular form. Since their definition in 2010 by Zagier, quantum modular forms have been connected to numerous different topics such as strongly unimodal sequences, ranks, cranks, and asymptotics for mock theta functions. Motivated by Zagier's example of the quantum modularity of Kontsevich's "strange" function F(q), we revisit work of Andrews, Jimenez-Urroz, and Ono to construct a natural vector-valued quantum modular form whose components. The final chapter of this thesis is devoted to a study of asymptotics of mock theta functions near roots of unity. In his famous deathbed letter, Ramanujan introduced the notion of a mock theta function, and he offered some alleged examples. The theory of mock theta functions has been brought to fruition using the framework of harmonic Maass forms, thanks to Zwegers. Despite this understanding, little attention has been given to Ramanujan's original definition. Here we prove that Ramanujan's examples do indeed satisfy his

    1999-11-01

    This study examined the information-seeking strategies and science content understandings learners developed as a result of using on-line resources in the University of Michigan Digital Library and on the World Wide Web. Eight pairs of sixth grade students from two teachers' classrooms were observed during inquiries for astronomy, ecology, geology, and weather, and a final transfer task assessed learners' capabilities at the end of the school year. Data included video recordings of students' screen activity and conversations, journals and completed activity sheets, final artifacts, and semi-structured interviews. Learners' information-seeking strategies included activities related to asking, planning, tool usage, searching, assessing, synthesizing, writing, and creating. Analysis of data found a majority of learners posed meaningful, openended questions, used technological tools appropriately, developed pertinent search topics, were thoughtful in queries to the digital library, browsed sites purposefully to locate information, and constructed artifacts with novel formats. Students faced challenges when planning activities, assessing resources, and synthesizing information. Possible explanations were posed linking pedagogical practices with learners' growth and use of inquiry strategies. Data from classroom-lab video and teacher interviews showed varying degrees of student scaffolding: development and critique of initial questions, utilization of search tools, use of journals for reflection on activities, and requirements for final artifacts. Science content understandings included recalling information, offering explanations, articulating relationships, and extending explanations. A majority of learners constructed partial understandings limited to information recall and simple explanations, and these occasionally contained inaccurate conceptualizations. Web site design features had some influence on the construction of learners' content understandings. Analysis of

  1. The relationship between nature of science understandings and science self-efficacy beliefs of sixth grade students

    Science.gov (United States)

    Parker, Elisabeth Allyn

    Bandura (1986) posited that self-efficacy beliefs help determine what individuals do with the knowledge and skills they have and are critical determinants of how well skill and knowledge are acquired. Research has correlated self-efficacy beliefs with academic success and subject interest (Pajares, Britner, & Valiante, 2000). Similar studies report a decreasing interest by students in school science beginning in middle school claiming that they don't enjoy science because the classes are boring and irrelevant to their lives (Basu & Barton, 2007). The hypothesis put forth by researchers is that students need to observe models of how science is done, the nature of science (NOS), so that they connect with the human enterprise of science and thereby raise their self-efficacy (Britner, 2008). This study examined NOS understandings and science self-efficacy of students enrolled in a sixth grade earth science class taught with explicit NOS instruction. The research questions that guided this study were (a) how do students' self-efficacy beliefs change as compared with changes in their nature of science understandings?; and (b) how do changes in students' science self-efficacy beliefs vary with gender and ethnicity segregation? A mixed method design was employed following an embedded experimental model (Creswell & Plano Clark, 2007). As the treatment, five NOS aspects were first taught by the teachers using nonintegrated activities followed by integrated instructional approach (Khishfe, 2008). Students' views of NOS using the Views on Nature of Science (VNOS) (Lederman, Abd-El-Khalick, & Schwartz, 2002) along with their self-efficacy beliefs using three Likert-type science self-efficacy scales (Britner, 2002) were gathered. Changes in NOS understandings were determined by categorizing student responses and then comparing pre- and post-instructional understandings. To determine changes in participants' self-efficacy beliefs as measured by the three subscales, a multivariate

    Full Text Available Knowing that Messiaen's early period, especially The Quartet for the End of Time, got so many written comments and discussions and from renowned critics, musicologists and composers it is hard to believe that anything different could possibly come out about the structure, form or concept in his work. Still, another look at these works would be valuable, since the concept of form is far from explored. The focal point of this text is the sixth movement from the Quartet and its concept of form. It unveils the relation between Messiaen's music ideas and the ancient Greek tragedy and the depth of the influence that Greek art had on his concept of form. The influence goes as far as the "suggestion of ring composition".

    Rising marijuana use and its lowered perceived risk among adolescents highlight the importance of examining patterns of marijuana use over time. This study identified trajectories of marijuana use among adolescents followed from middle through high school, characterized these by co-occurring problem behaviors and teacher-rated academic skills (study skills, attention problems, and learning problems), and tested sixth-grade predictors of trajectory membership. The sample consisted of a randomly-selected cohort of 619 students assessed annually from sixth to twelfth grade. Using group-based modeling, we identified four trajectories of marijuana use: Abstainer (65.6%), Sporadic (13.9%), Experimental (11.5%), and Increasing (9.0%). Compared to Abstainers, students in the Sporadic, Experimental and Increasing trajectories reported significantly more co-occurring problem behaviors of alcohol use, cigarette smoking, and physical aggression. Sporadic and Experimental users reported significantly less smoking and physical aggression, but not alcohol use, than Increasing users. Teachers consistently rated Abstainers as having better study skills and less attention and learning problems than the three marijuana use groups. Compared to Abstainers, the odds of dropping out of high school was at least 2.7 times higher for students in the marijuana use trajectories. Dropout rates did not vary significantly between marijuana use groups. In sixth grade, being male, cigarette smoking, physical aggression and attention problems increased the odds of being in the marijuana use trajectories. Multiple indicators--student self-reports, teacher ratings and high school dropout records--showed that marijuana was not an isolated or benign event in the life of adolescents but part of an overall problem behavior syndrome.

    Superplasticity in ceramics has now advanced to the stage that technologically viable superplastic deformation processing can be performed. In this paper, examples of superplastic forming and diffusion bonding of ceramic components are given. Recent work in biaxial gas-pressure forming of several ceramics is provided. These include yttria-stabilized, tetragonal zirconia (YTZP), a 20% alumina/YTZP composite, and silicon. In addition, the concurrent superplastic forming and diffusion bonding of a hybrid ceramic-metal structure are presented. These forming processes offer technological advantages of greater dimensional control and increased variety and complexity of shapes than is possible with conventional ceramic shaping technology.

  10. Differentiating mass from density: The effect of modeling and student dialogue in a sixth-grade classroom

    Science.gov (United States)

    Deich, Martha L.

    selected an intervention class and a comparison class from those I was teaching. The core of the density curriculum was similar in both classes. Instead of the intervention, though, the comparison class closely followed the lesson sequences provided by the classroom textbook, which tended to focus on formal and formulaic density instruction. I modified Smith's assessments for sixth graders. After teaching one class the intervention curriculum and the other the textbook-based curriculum, I evaluated and compared the progress of research participants in both classrooms by means of a pre- and post-instruction clinical interview, a pre- and post-instruction written test, and the end-of-chapter test from the textbook used in the comparison classroom. The results of my study were consistent: the intervention students outperformed and showed greater improvement on all assessments compared to the comparison students. In this study, modeling and student discourse were more effective ways to teach density than a standard textbook-based lesson sequence. The intervention helped students start to disrupt the conflation of mass and density, fostering both the comprehension of volume as a variable property of matter, and a nuanced understanding of density beyond formulaic reasoning. This dissertation is a report of my study for two audiences---academics and science educators. For the latter, I include recommendations for improving density instruction that are informed by my research.

    Full Text Available Aim: The present study was undertaken to compare and evaluate shear bond strength of two self-etching adhesives (sixth and seventh generation on dentin of primary and permanent teeth. Materials and Methods: Flat dentin surface of 64 human anterior teeth (32 primary and 32 permanent divided into four groups of 16 each. Groups A and C were treated with Contax (sixth generation, while groups B and D were treated with Clearfil S3 (seventh generation. A teflon mold was used to build the composite (Filtek Z-350 cylinders on the dentinal surface of all the specimens. Shear bond strength was tested for all the specimens with an Instron Universal Testing Machine. Data were statistically analyzed using one-way ANOVA for multiple group comparison, followed by student′s unpaired ′t′ test for group-wise comparison. Results: There was no statistically significant difference in shear bond strength among the study groups except that primary teeth bonded with Contax exhibited significantly lesser shear bond strength than permanent teeth bonded with Clearfil S3. Conclusion: This study revealed that Clearfil S3 could be of greater advantage in pediatric dentistry than Contax because of its fewer steps and better shear bond strength in dentin of both primary and permanent teeth.

    2014-12-01

    This paper presents the results obtained during the measurements campaign started in June 2012 and ended in November 2013 on the invaluable purple Codex Rossanensis, sixth century, one of the oldest surviving illuminated manuscripts of the New Testament. The tasks of the chemistry laboratory were to answer a variety of questions posed both by historians and restorers, concerning the materials used in a previous restoration, the composition of the pictorial palette and the different inks and to determine which colouring material had been applied to dye the parchment support. It was also requested to determine the state of preservation of the manuscript, as a result of its interactions with the environment in which the manuscript had been stored and the vicissitudes experienced during its life (fire, previous restoration, exhibition). The spectroscopic analyses performed by micro-Raman, micro-Fourier transform infrared and X-ray fluorescence allowed to fill a gap in the knowledge of the pictorial materials used in the Early Middle Ages. The pictorial palette, the inks, the dye applied to obtain the purple parchments, the support and the materials used in the previous restoration treatment executed in 1917-19 were fully characterised. Moreover, to the author's knowledge, the article shows the first experimental evidence of the use of the elderberry lake in a sixth century-illuminated manuscript. The lake was characterised by Raman spectroscopy.

    2011-04-01

    Full Text Available Abstract Background The role of episiotomy as a protective factor against pelvic floor disorders postpartum has been debated for many years, but its routine use has been hitherto discouraged in the literature. Comparisons between restrictive and routine use of episiotomy in existent literature, however, fail to include any consideration relating to quality of life. The aim of this study, therefore, is to state the role of episiotomy in preserving the perineum from damage, in order to prevent the influence of pelvic floor disorders on women's psycho-physical wellness after the sixth month postpartum. Methods A follow-up telephone interview was performed among 377 primiparous and secondiparous Caucasian women who had a child by spontaneous or operative vaginal delivery in 2006 using a self-created questionnaire and King's Health Questionnaire (KHQ. Results The mean age at delivery was 35.26 (±4.68 years and episiotomy was performed in 59.2% of women. Multivariate linear regression shows episiotomy associated to higher quality of life after the sixth month postpartum by correlating with inferior values of King's Health Questionnaire (p Conclusions Episiotomy appears to be a protective factor for women's wellness. Women who had episiotomy and who experienced perineal symptoms have a better psycho-physical health status in the 12.79 months (±3.3 follow-up.

    Bendix product applications require the capability of fabricating heavy gage, high strength materials. Five commercial sources have been identified that have the capability of spin forming metal thicknesses greater than 9.5 mm and four equipment manufacturers produce machines with this capability. Twelve assemblies selected as candidates for spin forming applications require spin forming of titanium, 250 maraging steel, 17-4 pH stainless steel, Nitronic 40 steel, 304 L stainless steel, and 6061 aluminum. Twelve parts have been cold spin formed from a 250 maraging steel 8.1 mm wall thickness machine preform, and six have been hot spin formed directly from 31.8-mm-thick flat plate. Thirty-three Ti-6Al-4V titanium alloy parts and 26 17-4 pH stainless steel parts have been hot spin formed directly from 31.8-mm-thick plate. Hot spin forming directly from plate has demonstrated the feasibility and favorable economics of this fabrication technique for Bendix applications.

    Kratky, Alexander

    2007-05-01

    During forming processes high deformations rates can lead to cracks and rupture very easily. Especially brittle materials like titanium or magnesium make difficulties in forming. Due to the dependence of the yield strength on temperature, forming at elevated temperatures eases processing of such materials. Since forming takes place only at localized areas of the work piece selective heating is suffcient and advantageous in most cases. Selective Laser heating offers a possibility to heat only the areas of the work piece where strongest deformations are required. For this purpose several laser sources have been tested like CO II, Diode and Nd:YAG Lasers and their advantages and disadvantages in localized heating of the work pieces will be discussed. The work presented here summarizes research activities at the Institute for Forming and High Power Laser Technology, Vienna University of Technology, on laser assisted deep drawing, laser assisted bending, wire drawing and so on during the last decade. Recent developments like roll profiling, incremental forming processes and hydro forming are discussed briefly.

    2009-01-01

    The theory of defects in ordered and ill-ordered media is a well-advanced part of condensed matter physics. Concepts developed in this field also occur in the study of spacetime singularities, namely: i)- the topological theory of quantized defects (Kibble's cosmic strings) and ii)- the Volterra process for continuous defects, used to classify the Poincar\\'e symmetry breakings. We reassess the classification of Minkowski spacetime defects in the same theoretical frame, starting from the conjecture that these defects fall into two classes, as on they relate to massive particles or to radiation. This we justify on the empirical evidence of the Hubble's expansion. We introduce timelike and null congruences of geodesics treated as ordered media, viz. 'm'-crystals of massive particles and 'r'-crystals of massless particles, with parallel 4-momenta in M^4. Classifying their defects (or 'forms') we find (i) 'm'- and 'r'- Volterra continuous line defects and (ii) quantized topologically stable 'r'-defects, these latt...

    Once again Journal of Neural Engineering is devoting an issue to the field of visual neuro-prosthetics. These papers were presented at the Sixth Biennial Research Congress of The Eye and the ChipA 13 DVD set of all presentations at The Eye and the Chip 2010 is available from Carolyn Barth PhD, Detroit Institute of Ophthalmology, 15415 E Jefferson, Grosse Pointe Park MI 48230, USA, 313.824.4710, clbarth@dioeyes.org, held in Detroit in September 2010. In the last decade this field has metamorphosed from 'in all probability a foolish and impractical dream' to a device approved for implantation in Europe and pending approval in the United States, and from a handful of serious efforts to several dozen on every continent save for Antartica. A recent comprehensive volume, Visual Prosthetics [1], edited by Gislin Dagnelie of Johns Hopkins University School of Medicine, focuses closely on this subject and is a tremendous addition to the literature. In his preface Dr Dagnelie notes as follows. 'In the year 2000, the Detroit Institute of Ophthalmology had the inspiration to foster a new collaboration among visual prosthesis researchers, clinicians, and workers in low vision rehabilitation by creating and sponsoring a series of biennial meetings called 'The Eye and the Chip'. Successful beyond expectations, these meetings have become the premier gathering place for researchers from all parts of the world and from very different backgrounds. Invited speakers are scientists who are advancing the field, yet the scale and atmosphere allow all researchers, patients, and the media to come and be updated about progress over the past two years. More perhaps than at other scientific meetings, where investigators tend to gather within disciplines, participants at The Eye and the Chip are challenged to be open-minded, learn about and critique each other's work, and return home with fresh ideas for interdisciplinary approaches. The interdisciplinary character of this book reflects that

  13. Achieving form in autobiography

    Directory of Open Access Journals (Sweden)

    Nicholas (Nick Meihuizen

    2014-06-01

    Full Text Available This article argues that, unlike biographies which tend to follow patterns based on conventional expectations, salient autobiographies achieve forms unique to themselves. The article draws on ideas from contemporary formalists such as Peter McDonald and Angela Leighton but also considers ideas on significant form stemming from earlier writers and critics such as P.N. Furbank and Willa Cather. In extracting from these writers the elements of what they consider comprise achieved form, the article does not seek to provide a rigid means of objectively testing the formal attributes of a piece of writing. It rather offers qualitative reminders of the need to be alert to the importance of form, even if the precise nature of this importance is not possible to define. Form is involved in meaning, and this continuously opens up possibilities regarding the reader’s relationship with the work in question. French genetic critic Debray Genette distinguishes between ‘semantic effect’ (the direct telling involved in writing and ‘semiological effect’ (the indirect signification involved. It is the latter, the article argues in summation, which gives a work its singular nature, producing a form that is not predictable but suggestive, imaginative.

  14. FormFlavor Manual

    Evans, Jared A

    2016-01-01

    This manual describes the usage and structure of FormFlavor, a Mathematica-based tool for computing a broad list of flavor and CP observables in general new physics models. Based on the powerful machinery of FeynArts and FormCalc, FormFlavor calculates the one-loop Wilson coefficients of the dimension 5 and 6 Standard Model effective Lagrangian entirely from scratch. These Wilson coefficients are then evolved down to the low scale using one-loop QCD RGEs, where they are transformed into flavor and CP observables. The last step is accomplished using a model-independent, largely stand-alone package called FFObservables that is included with FormFlavor. The SM predictions in FFObservables include up-to-date references and accurate current predictions. Using the functions and modular structure provided by FormFlavor, it is straightforward to add new observables. Currently, FormFlavor is set up to perform these calculations for the general, non-MFV MSSM, but in principle it can be generalized to arbitrary FeynArts...

  15. Comparative waste forms study

    1980-12-01

    A number of alternative process and waste form options exist for the immobilization of nuclear wastes. Although data exists on the characterization of these alternative waste forms, a straightforward comparison of product properties is difficult, due to the lack of standardized testing procedures. The characterization study described in this report involved the application of the same volatility, mechanical strength and leach tests to ten alternative waste forms, to assess product durability. Bulk property, phase analysis and microstructural examination of the simulated products, whose waste loading varied from 5% to 100% was also conducted. The specific waste forms investigated were as follows: Cold Pressed and Sintered PW-9 Calcine; Hot Pressed PW-9 Calcine; Hot Isostatic Pressed PW-9 Calcine; Cold Pressed and Sintered SPC-5B Supercalcine; Hot Isostatic pressed SPC-5B Supercalcine; Sintered PW-9 and 50% Glass Frit; Glass 76-68; Celsian Glass Ceramic; Type II Portland Cement and 10% PW-9 Calcine; and Type II Portland Cement and 10% SPC-5B Supercalcine. Bulk property data were used to calculate and compare the relative quantities of waste form volume produced at a spent fuel processing rate of 5 metric ton uranium/day. This quantity ranged from 3173 L/day (5280 Kg/day) for 10% SPC-5B supercalcine in cement to 83 L/day (294 Kg/day) for 100% calcine. Mechanical strength, volatility, and leach resistance tests provide data related to waste form durability. Glass, glass-ceramic and supercalcine ranked high in waste form durability where as the 100% PW-9 calcine ranked low. All other materials ranked between these two groupings.

    2012-01-01

    The current state of the art in the development of methodologies for the preparation of MIPs in predetermined physical forms is critically reviewed, with particular attention being paid to the forms most widely employed in practical applications, such as spherical beads in the micro- to nanometer range, microgels, monoliths, membranes. Although applications of the various MIP physical forms are mentioned, the focus of the paper is mainly on the description of the various preparative methods. The aim is to provide the reader with an overview of the latest achievements in the field, as well as with a mean for critically evaluating the various proposed methodologies towards an envisaged application. The review covers the literature up to early 2010, with special emphasis on the developments of the last 10 years.

    Single source precursors or pre-copolymers of single source precursors are subjected to microwave radiation to form particles of a I-III-VI.sub.2 material. Such particles may be formed in a wurtzite phase and may be converted to a chalcopyrite phase by, for example, exposure to heat. The particles in the wurtzite phase may have a substantially hexagonal shape that enables stacking into ordered layers. The particles in the wurtzite phase may be mixed with particles in the chalcopyrite phase (i.e., chalcopyrite nanoparticles) that may fill voids within the ordered layers of the particles in the wurtzite phase thus produce films with good coverage. In some embodiments, the methods are used to form layers of semiconductor materials comprising a I-III-VI.sub.2 material. Devices such as, for example, thin-film solar cells may be fabricated using such methods.

    Ratanapojnard, Sorrayut

    The goals of this study were to (a) develop and implement Community-Orient Biodiversity Environmental Education (COBEE) program in Buriram, northeastern Thailand; and (b) determine its effect on biodiversity-related knowledge, values, and behavior among rural fifth- and sixth-grade students. Local teachers, community leaders, and the author, in association with Thailand's Ministry of Education, together developed a multidisciplinary curriculum to study the community of Satuk, Buriram---its history, lifestyles, and economy, and how these were interconnected with biodiversity issues. The COBEE program provided intensive and ongoing teacher training workshops, supervisory visits, and support group meetings for teachers. Over the 1996--1997 academic year, teachers delivered the COBEE curriculum using both indoor and outdoor activities, including community studies, interviews with local people, developing a species inventory with descriptions of biology, habitats, and uses, and field trips to agricultural fields, local forests, and protected areas. Seven primary schools were randomly assigned as four experimental and three control schools. There were 218 and 198 fifth- and sixth-grade students in the experimental and control schools respectively. The Solomon four-group research design was used to compare students before and after the COBEE program. A set of survey instruments was developed to gather quantitative data. Qualitative data were collected from interviews, participant observations, and students' schoolwork. Three major findings are: (1) An environmental education program can be designed and implemented to produce positive effects not only on objectives identified as the foundation of environmental education (e.g., knowledge, attitudes, and behavior), but also on students' other academic attitudes and development. (2) Based on qualitative data, the relative success of COBEE indicates that curriculum, instruction, nature experience, and other facilitating

    The Earth's surface has a dynamic and topographically varied natural landscape. In some cases the resulting landforms are given generic names reflecting their form and/or origin, (e.g. sand dunes, eskers, ox-bow lakes) but in many cases the land surface has a more amorphous form and is less easily categorized other than at a landscape scale (e.g. dissected plateau, Chalk downland). Across much of Europe, while the natural vegetation has been removed or radically modified, the natural land form/topography remains in tact. In this context and in terms of geoconservation we ought to be: • allowing the dynamic natural processes that create, carve and modify landscapes to continue to operate; and • retaining natural topographic character and geomorphological authenticity in the face of human actions seeking to remodel the land surface. In this presentation examples of this approach to geoconservation of land form will be given from the UK and other parts of the world. This will include examples of both appropriate and inappropriate topographic modifications.

    Cosmology of self-interacting three-forms is investigated. The minimally coupled canonical theory can naturally generate a variety of isotropic background dynamics, including scaling, possibly transient acceleration and phantom crossing. An intuitive picture of the cosmological dynamics is presented employing an effective potential. Numerical solutions and analytical approximations are provided for scenarios which are potentially important for inflation or dark energy.

  11. Classical seventh-, sixth-, and fifth-order Runge-Kutta-Nystrom formulas with stepsize control for general second-order differential equations

    Science.gov (United States)

    Fehlberg, E.

    1974-01-01

    Runge-Kutta-Nystrom formulas of the seventh, sixth, and fifth order were derived for the general second order (vector) differential equation written as the second derivative of x = f(t, x, the first derivative of x). The formulas include a stepsize control procedure, based on a complete coverage of the leading term of the local truncation error in x, and they require no more evaluations per step than the earlier Runge-Kutta formulas for the first derivative of x = f(t, x). The developed formulas are expected to be time saving in comparison to the Runge-Kutta formulas for first-order differential equations, since it is not necessary to convert the second-order differential equations into twice as many first-order differential equations. The examples shown saved from 25 percent to 60 percent more computer time than the earlier formulas for first-order differential equations, and are comparable in accuracy.

    We investigate the measurement of the sixth order cumulant and its ratio to the second order cumulant ($C_6/C_2$) in relativistic heavy-ion collisions. The influence of statistics and different methods of centrality bin width correction on $C_6/C_2$ of net-proton multiplicity distributions is demonstrated. There is no satisfactory method to extract $C_6/C_2$ with the current statistics recorded at lower energies by STAR at RHIC. With statistics comparable to the expected statistics at the planned future RHIC Beam Energy Scan II (BES II), no energy dependence of $C_6/C_2$ is observed in central collisions using the UrQMD model. We find if the transition signal is as strong as predicted by the PQM model, then it is hopefully observed at the upcoming RHIC BES II.

    2014-06-01

    The current study is a pilot trial to examine the effects of a nonelective, classroom-based, teacher-implemented, mindfulness meditation intervention on standard clinical measures of mental health and affect in middle school children. A total of 101 healthy sixth-grade students (55 boys, 46 girls) were randomized to either an Asian history course with daily mindfulness meditation practice (intervention group) or an African history course with a matched experiential activity (active control group). Self-reported measures included the Youth Self Report (YSR), a modified Spielberger State-Trait Anxiety Inventory, and the Cognitive and Affective Mindfulness Measure -Revised. Both groups decreased significantly on clinical syndrome subscales and affect but did not differ in the extent of their improvements. Meditators were significantly less likely to develop suicidal ideation or thoughts of self-harm than controls. These results suggest that mindfulness training may yield both unique and non-specific benefits that are shared by other novel activities.

    The consumption of non-ready-to-eat cereal and ready-to-eat cereal (RTEC) breakfasts have been associated with increased nutrient intakes and lower body mass index (BMI). These relationships have not been examined in low-income minority children. To evaluate, in low-income minority children, whether there is a relationship among the frequency of RTEC consumption and nutrient intakes measured at baseline, and whether there is a relationship between the frequency of RTEC and BMI controlling for age, sex, ethnicity, and energy intake. A longitudinal study design where a cohort was followed for 3 years. Participants were 625 fourth- through sixth-grade, low-income children living in San Antonio, Texas, and enrolled in the control arm of the Bienestar Diabetes Prevention Program's cluster randomized trial. Three multiple-pass 24-hour dietary recalls were collected at the beginning of their fourth-grade year and at the end of their fifth- and sixth-grade years. Children's age, sex, ethnicity, and height and weight (used to calculate BMI) were collected between August 2001 and May 2004. Descriptive and inferential statistical analyses were performed. The frequency of breakfast consumption was examined using a 6×4 cross-tabulation table with χ(2) test to establish categorical differences. The degree of association between BMI percentile and frequency of RTEC consumption adjusted for age, sex, ethnicity, and nutrition-related parameters were calculated using a partial correlation multivariate linear model analysis. There was a significant positive relationship between the frequency of RTEC consumption and nutrient intakes measured at baseline. There was also a significant inverse relationship between frequency of RTEC consumption and BMI percentile over the cumulative 3-year period controlling for age, sex, ethnicity, and energy intake. Children who frequently consumed RTEC had greater intakes of essential nutrients at baseline and significantly lower BMI over a 3-year

    2016-01-01

    Angiogenesis involves the generation of new blood vessels from the existing vasculature and is dependent on many growth factors and signaling events. In vivo angiogenesis is dynamic and complex, meaning assays are commonly utilized to explore specific targets for research into this area. Tube-forming assays offer an excellent overview of the molecular processes in angiogenesis. The Matrigel tube forming assay is a simple-to-implement but powerful tool for identifying biomolecules involved in angiogenesis. A detailed experimental protocol on the implementation of the assay is described in conjunction with an in-depth review of methods that can be applied to the analysis of the tube formation. In addition, an ImageJ plug-in is presented which allows automatic quantification of tube images reducing analysis times while removing user bias and subjectivity.

    2014-01-01

    Many socioeconomic studies have been carried out to explain the phenomenon of gentrification. Although results of these works shed light on the process around this phenomenon, a perspective which focuses on the relationship between city form and gentrification is still missing. With this paper we try to address this gap by studying and comparing, through classic methods of mathematical statistics, morphological features of five London gentrified neighbourhoods. Outcomes confirm that areas which have undergone gentrification display similar and recognizable morphological patterns in terms of urban type and geographical location of main and local roads as well as businesses. These initial results confirm findings from previous research in urban sociology, and highlight the role of urban form in contributing to shape dynamics of non-spatial nature in cities.

  3. Nucleon Electromagnetic Form Factors

    Kees de Jager

    2004-08-01

    Although nucleons account for nearly all the visible mass in the universe, they have a complicated structure that is still incompletely understood. The first indication that nucleons have an internal structure, was the measurement of the proton magnetic moment by Frisch and Stern (1933) which revealed a large deviation from the value expected for a point-like Dirac particle. The investigation of the spatial structure of the nucleon, resulting in the first quantitative measurement of the proton charge radius, was initiated by the HEPL (Stanford) experiments in the 1950s, for which Hofstadter was awarded the 1961 Nobel prize. The first indication of a non-zero neutron charge distribution was obtained by scattering thermal neutrons off atomic electrons. The recent revival of its experimental study through the operational implementation of novel instrumentation has instigated a strong theoretical interest. Nucleon electro-magnetic form factors (EMFFs) are optimally studied through the exchange of a virtual photon, in elastic electron-nucleon scattering. The momentum transferred to the nucleon by the virtual photon can be selected to probe different scales of the nucleon, from integral properties such as the charge radius to scaling properties of its internal constituents. Polarization instrumentation, polarized beams and targets, and the measurement of the polarization of the recoiling nucleon have been essential in the accurate separation of the charge and magnetic form factors and in studies of the elusive neutron charge form factor.

    The adhesive cutaneous pharmaceutical forms aimed to local action release the drug substance in view of a dermatological, traumatological, antirheumatic, cosmetic action. Two such preparations were obtained and their stability, consistency and pH were determined. The "in vitro" tests of their bioavailability revealed the dynamics of calcium ions release according to the associations of each preparation. The bioavailability determined by evaluating the pharmacological response demonstrated the antiinflammatory action obtained by the association of calcium ions with the components extracted from poplar muds. The therapeutical efficiency of the studied preparations has proved in the treatment of some sport injuries.

    Full Text Available Forming is usually the final stage of metallurgical production of steel (90 % of the 1,7 billion tons of total steel production in the world and traditionally also largely of the products made of non-ferrous metals. Many procedures and methods exist and we will focus only on some of them. The aim is usually to achieve ultra-fine grained structure, the proper microstructure and (mechanical / electrical properties in innovative materials.

    2013-01-01

    We describe the implementation of output code optimization in the open source computer algebra system FORM. This implementation is based on recently discovered techniques of Monte Carlo tree search to find efficient multivariate Horner schemes, in combination with other optimization algorithms, such as common subexpression elimination. For systems for which no specific knowledge is provided it performs significantly better than other methods we could compare with. Because the method has a number of free parameters, we also show some methods by which to tune them to different types of problems.

  10. Do naked singularities form?

    CERN Document Server

    Vaz, C; Vaz, Cenalo; Witten, Louis

    1995-01-01

    A naked singularity is formed by the collapse of a Sine-Gordon soliton in 1+1 dimensional dilaton gravity with a negative cosmological constant. We examine the quantum stress tensor resulting from the formation of the singularity. Consistent boundary conditions require that the incoming soliton is accompanied by a flux of incoming radiation across past null infinity, but neglecting the back reaction of the spacetime leads to the absurd conclusion that the total energy entering the system by the time the observer is able to receive information from the singularity is infinite. We conclude that the back reaction must prevent the formation of the naked singularity.

    A bipolar pulse forming transmission line module for linear induction accelerators having first, second, third, fourth, and fifth planar conductors which form an interleaved stack with dielectric layers between the conductors. Each conductor has a first end, and a second end adjacent an acceleration axis. The first and second planar conductors are connected to each other at the second ends, the fourth and fifth planar conductors are connected to each other at the second ends, and the first and fifth planar conductors are connected to each other at the first ends via a shorting plate adjacent the first ends. The third planar conductor is electrically connectable to a high voltage source, and an internal switch functions to short a high voltage from the first end of the third planar conductor to the first end of the fourth planar conductor to produce a bipolar pulse at the acceleration axis with a zero net time integral. Improved access to the switch is enabled by an aperture through the shorting plate and the proximity of the aperture to the switch.

    Full Text Available The prophecy is a kind of text holding therefore its own textual marks, differing from other kinds of texts. In order to do a discursive analysis of it, we must bring a semiotic study of its own possible forms. It includes its intertextual connections, as well as the use of typical tropos and topoi. Our aim is to describe the features of a kind of text that seems to appear in every well-known culture. Our analysis is limited to religious prophecies, showing mainly several examples from Judeo-Christian tradition, but also from other cultures, according to our line of argument. Amongst its features we find the use of allusion, forcing to any addressee to expand all possible interpretations. Likewise the prophecy seems to fulfill the double function of threat/promise, depending on each addressee.

    Full Text Available Modern studies emphasized on the needs of researching the hospitality as relevant aspects of tourism and hospitality fields. Anyway, these approaches are inextricably intertwined to the industry of tourism and do not take seriously the anthropological and sociological roots of hospitality. In fact, the hotel seems to be a partial sphere of hospitality at all. Under this context, the present paper explores the issue of hospitality enrooted in the political and economic indo-European principle of free-transit which is associated to a much broader origin.  Starting from the premise etymologically hostel and hospital share similar origins, we follow the contributions of J Derrida to determine the elements that formed the hospitality up to date.

    We classify Siegel modular cusp forms of weight two for the paramodular group K(p) for primes p< 600. We find that weight two Hecke eigenforms beyond the Gritsenko lifts correspond to certain abelian varieties defined over the rationals of conductor p. The arithmetic classification is in a companion article by A. Brumer and K. Kramer. The Paramodular Conjecture, supported by these computations and consistent with the Langlands philosophy and the work of H. Yoshida, is a partial extension to degree 2 of the Shimura-Taniyama Conjecture. These nonlift Hecke eigenforms share Euler factors with the corresponding abelian variety $A$ and satisfy congruences modulo \\ell with Gritsenko lifts, whenever $A$ has rational \\ell-torsion.

    It is pointed out that the correct criterion to define the legal PQCD contribution to the exclusive processes in the lightcone perturbative expansion should be based on the large off-shellness of the lightcone energy in the intermediate states. In the lightcone perturbative QCD calculation of the pion form factor, the authors find that the legal PQCD contribution defined by the lightcone energy cut saturates in the smaller Q{sup 2} region compared to that defined by the gluon four-momentum square cut. This is due to the contribution by the highly off-energy-shell gluons in the end point regions of the phase space, indicating that the gluon four-momentum-square cut may have cut too much to define the legal PQCD.

    There has been much activity in the measurement of the elastic electromagnetic proton and neutron form factors in the last decade, and the quality of the data has greatly improved by performing double polarization experiments, in comparison with previous unpolarized data. Here we review the experimental data base in view of the new results for the proton, and neutron, obtained at JLab, MAMI, and MIT-Bates. The rapid evolution of phenomenological models triggered by these high-precision experiments will be discussed, including the recent progress in the determination of the valence quark generalized parton distributions of the nucleon, as well as the steady rate of improvements made in the lattice QCD calculations.

    It is often assumed that children go through a stage in which they systematically overapply irregular past tense patterns to inappropriate verbs, as in wipe-wope, bring-brang, trick-truck, walk-has walken. Such errors have been interpreted both as reflecting over-use of minor grammatical rules (e.g. 'change i to a'), and as reflecting the operation of a connectionist pattern associator network that superimposes and blends patterns of various degrees of generality. But the actual rate, time course, and nature of these errors have never been documented. We analysed 20,000 past tense and participle usages from nine children in the CHILDES database, looking for overapplications of irregular vowel-change patterns, as in brang, blends, as in branged, productive suffixations of -en, as in walken, gross distortions, as in mail-membled, and double-suffixation, as in walkeded. These errors were collectively quite rare; children made them in about two tenths of one per cent of the opportunities, and with few stable patterns: the errors were not predominantly word-substitutions, did not occur predominantly with irregular stems, showed no consistency across verbs or ages, and showed no clear age trend. Most (though not all) of the errors were based closely on existing irregular verbs; gross distortions never occurred. We suggest that both rule-theories and connectionist theories have tended to overestimate the predominance of such errors. Children master irregular forms quite accurately, presumably because irregular forms are just a special case of the arbitrary sound-meaning pairings that define words, and because children are good at learning words.

    What causes the large-scale spiral structures found in some protoplanetary disks? Most models assume theyre created by newly-forming planets, but a new study suggests that planets might have nothing to do with it.Perturbations from Planets?In some transition disks protoplanetary disks with gaps in their inner regions weve directly imaged large-scale spiral arms. Many theories currently attribute the formation of these structures to young planets: either the direct perturbations of a planet embedded in the disk cause the spirals, or theyre indirectly caused by the orbit of a planetary body outside of the arms.Another example of spiral arms detected in a protoplanetary disk, MWC 758. [NASA/ESA/ESO/M. Benisty et al.]But what if you could get spirals without any planets? A team of scientists led by Matas Montesinos (University of Chile) have recently published a study in which they examine what happens to a shadowed protoplanetary disk.Casting Shadows with WarpsIn the teams setup, they envision a protoplanetary disk that is warped: the inner region is slightly tilted relative to the outer region. As the central star casts light out over its protoplanetary disk, this disk warping would cause some regions of the disk to be shaded in a way that isnt axially symmetric with potentially interesting implications.Montesinos and collaborators ran 2D hydrodynamics simulations to determine what happens to the motion of particles within the disk when they pass in and out of the shadowed regions. Since the shadowed regions are significantly colder than the illuminated disk, the pressure in these regions is much lower. Particles are therefore accelerated and decelerated as they pass through these regions, and the lack of axial symmetry causes spiral density waves to form in the disk as a result.Initial profile for the stellar heating rate per unit area for one of the authors simulations. The regions shadowed as a result of the disk warp subtend 0.5 radians each (shown on the left

    The purpose of this study was to investigate the impact of gender and type of inquiry curriculum (open or structured) on science process skills and epistemological beliefs in science of sixth grade students. The current study took place in an urban northeastern middle school. The researcher utilized a sample of convenience comprised of 303 sixth grade students taught by four science teachers on separate teams. The study employed mixed methods with a quasi-experimental design, pretest-posttest comparison group with 17 intact classrooms of students. Students' science process skills and epistemological beliefs in science (source, certainty, development, and justification) were measured before and after the intervention, which exposed different groups of students to different types of inquiry (structured or open). Differences between comparison and treatment groups and between male and female students were analyzed after the intervention, on science process skills, using a two-way analysis of covariance (ANCOVA), and, on epistemological beliefs in science, using a two-way multivariate analysis of covariance (MANCOVA). Responses from two focus groups of open inquiry students were cycle coded and examined for themes and patterns. Quantitative measurements indicated that girls scored significantly higher on science process skills than boys, regardless of type of inquiry instruction. Neither gender nor type of inquiry instruction predicted students' epistemological beliefs in science after accounting for students' pretest scores. The dimension Development accounted for 10.6% of the variance in students' science process skills. Qualitative results indicated that students with sophisticated epistemological beliefs expressed engagement with the open-inquiry curriculum. Students in both the sophisticated and naive beliefs groups identified challenges with the curriculum and improvement in learning as major themes. The types of challenges identified differed between the groups

    When the Earth was formed, it was in a state of burning heat. As time went by, temperature on the planet's surface was falling due to radiation and heat transfer, and various components (crusts) began taking solid form at the Earth's poles. The formation of crusts took place at the Earth's poles, because the stirring of burning and fluid masses on the surface of the Earth was significantly slighter there than it was on the equator. Due to centrifugal force and Coriolis Effect, these solid masses headed towards the equator; those originating from the North Pole followed a south-western course, while those originating from the South Pole followed a north-western course and there they rotated from west to east at a lower speed than the underlying burning and liquid earth, because of their lower initial linear velocity, their solid state and inertia. Because inertia is proportional to mass, the initially larger solid body swept all new solid ones, incorporating them to its western side. The density of the new solid masses was higher, because the components on the surface would freeze and solidify first, before the underlying thicker components. As a result, the western side of the initial islet of solid rocks submerged, while the east side elevated. . As a result of the above, this initial islet began to spin in reverse, and after taking on the shape of a sphere, it formed the "heart" of the Moon. The Moon-sphere, rolling on the equator, would sink the solid rocks that continued to descend from the Earth's poles. The sinking rocks partially melted because of higher temperatures in the greater depths that the Moon descended to, while part of the rocks' mass bonded with the Moon and also served as a heat-insulating material, preventing the descended side of the sphere from melting. Combined with the Earth's liquid mass that covered its emerging eastern surface, new sphere-shaped shells were created, with increased density and very powerful structural cohesion. During the

    In each of the 10 cases with propagators of unit or zero mass, the finite part of the scalar 3-loop tetrahedral vacuum diagram is reduced to 4-letter words in the 7-letter alphabet of the 1-forms $\\Omega:=dz/z$ and $\\omega_p:=dz/ yield only $\\zeta(Ømega^3ømega_0)=1/90\\pi^4$. In two cases $\\pi^4$ combines with the Euler-Zagier sum $\\zeta(Ømega^2ømega_3ømega_0)=\\sum_{m> n>0}(-1)^{m+n}/m^3n$; in three cases it combines with the square of Clausen's $Cl_2(\\pi/3)=\\Im \\zeta(Ømegaømega_1)=\\sum_{n>0}\\sin(\\pi n/3)/n^2$. The case with 6 masses involves no further constant; with 5 masses a Deligne-Euler-Zagier sum appears: $\\Re \\zeta(Ømega^2ømega_3ømega_1)= 3-loop rho-parameter of the standard model is merely $D_3=6\\zeta(3)-6 Cl_2^2(\\pi/3)-{1/24}\\pi^4$. The remarkable simplicity of these results stems from two shuffle algebras: one for nested sums; the other for iterated integrals. Each diagram evaluates to 10 000 digits in seconds, because the primitive words are transformable to exponentially convergent singl...

    We present a study of the earliest stages of massive star formation, in which we focus on Infrared Dark Clouds (IRDCs) and young massive clusters. We present Very Large Array spectral line observations of ammonia (NH 3) and CCS toward four IRDCs. The NH3 lines provide diagnostics of the temperature and density structure within IRDCs. Based upon the NH 3 column density, IRDCs have masses of ˜ 103 to 10 4 M⊙ . We detect twenty NH3 clumps within four IRDCs, with radii regions are presented from the Near Infrared Imager (NIRIM) camera on the 3.5 m WIYN telescope. We report J, H, and K' band photometry in the clusters AFGL437, AFGL5180, and AFGL5142 and use these results to probe the stellar populations, extinction, and ages of the clusters. We find that all three clusters suffer significant extinction (AK ˜1), have ages ≤ 5 Myr, and are actively forming stars. We conclude that the properties of these embedded clusters are consistent with their evolving from IRDC clumps.

  9. Watching How Planets Form

    Science.gov (United States)

    2006-09-01

    Anatomy of a Planet-Forming Disc around a Star More Massive than the Sun With the VISIR instrument on ESO's Very Large Telescope, astronomers have mapped the disc around a star more massive than the Sun. The very extended and flared disc most likely contains enough gas and dust to spawn planets. It appears as a precursor of debris discs such as the one around Vega-like stars and thus provides the rare opportunity to witness the conditions prevailing prior to or during planet formation. "Planets form in massive, gaseous and dusty proto-planetary discs that surround nascent stars. This process must be rather ubiquitous as more than 200 planets have now been found around stars other than the Sun," said Pierre-Olivier Lagage, from CEA Saclay (France) and leader of the team that carried out the observations. "However, very little is known about these discs, especially those around stars more massive than the Sun. Such stars are much more luminous and could have a large influence on their disc, possibly quickly destroying the inner part." The astronomers used the VISIR instrument [1] on ESO's Very Large Telescope to map in the infrared the disc surrounding the young star HD 97048. With an age of a few million years [2], HD 97048 belongs to the Chameleon I dark cloud, a stellar nursery 600 light-years away. The star is 40 times more luminous than our Sun and is 2.5 times as massive. The astronomers could only have achieved such a detailed view due to the high angular resolution offered by an 8-metre size telescope in the infrared, reaching a resolution of 0.33 arcsecond. They discovered a very large disc, at least 12 times more extended than the orbit of the farthest planet in the Solar System, Neptune. The observations suggest the disc to be flared. "This is the first time such a structure, predicted by some theoretical models, is imaged around a massive star," said Lagage.

    Purpose: Under war conditions, employed weapons can be identified on radiographs obtained in X-ray diagnostic. The analysis of such X-ray films allows concluding that there are additional information about the conditions of transport and treatment; it shall be shown that there are X-ray findings which are typical and characteristic for certain forms of warfare. Material and method: The radiograms have been collected during thirty years; they come from hospitals, where war casualties had been treated, and personal collections. Results: The material is selected, because in war X-ray diagnostic will be limited and the interest of the opposing parties influence the access to the material; furthermore the possibilities to publish or to communicate facts and thoughts are different. Citizens of the USA, GB, France, or Israel will have easier access to journals than those of Vietnam, Chad, and Zimbabwe. Under war conditions, poor countries, like North Vietnam may develop own concepts of medical care. There are X-ray findings which are typical or even characteristic for air warfare, guerrilla warfare, gas war, desert warfare, conventional warfare, and annihilation warfare, and city guerrilla warfare/civil war. The examples demonstrate that weapons and the conditions of transport and treatment can be recognized by X-ray findings. The radiogram can be read like a document. Conclusion: In War, there are differences between a treatment and imaging diagnostic in countries, which control the air space and in those who do not. Medical care of the poor, i.e. in countries (in general those opposing the western nations) will hardly be published, and poverty has no advocate.

    This paper reports the tenth-order contributions to the g-2 of the electron a_e and those of the muon a_mu from the gauge-invariant Set II(c), which consists of 36 Feynman diagrams, and Set II(d), which consists of 180 Feynman diagrams. Both sets are obtained by insertion of sixth-order vacuum-polarization diagrams in the fourth-order anomalous magnetic moment. The mass-independent contributions from Set II(c) and Set II(d) are -0.116 489 (32)(alpha/pi)^5 and -0.243 00 (29)(alpha/pi)^5, respectively. The leading contributions to a_mu, which involve electron loops only, are -3.888 27 (90)(alpha/pi)^5 and 0.4972 (65)(alpha/pi)^5 for Set II(c) and Set II(d), respectively. The total contributions of the electron, muon, and tau-lepton loops to a_e are -0.116 874 (32) (alpha/pi)^5 for Set II(c) and -0.243 10 (29) (alpha/pi)^5 for Set II(d). The contributions of electron, muon, and tau-lepton loops to a_mu are -5.5594 (11) (alpha/pi)^5 for Set II(c) and 0.2465 (65) (alpha/pi)^5 for Set II(d).

    This paper reports the tenth-order QED contribution to lepton g-2 from diagrams of three gauge-invariant sets VI(d), VI(g), and VI(h), which are obtained by including various fourth-order radiative corrections to the sixth-order g-2 containing light-by-light-scattering subdiagrams. In the case of electron g-2, they consist of 492, 480, and 630 vertex Feynman diagrams, respectively. The results of numerical integration, including mass-dependent terms containing muon loops, are 1.8418(95) (alpha/pi)^5 for the Set VI(d), -1.5918(65) (alpha/pi)^5 for the Set VI(g), and 0.1797(40) (alpha/pi)^5 for the Set VI(h), respectively. We also report the contributions to the muon g-2, which derive from diagrams containing an electron, muon or tau lepton loop: Their sums are -5.876(802) (alpha/pi)^5 for the Set VI(d), 5.710(490) (alpha/pi)^5 for the Set VI(g), and -8.361(232) (alpha/pi)^5 for the Set VI(h), respectively.

By using visual aids, expected that the teachers would be able to motivate them to learn and pay deep attention to the presentable materials by the teachers, so the students will not be tedious. This is an experimental research. The subject of the study is limited to the students of the sixth year of SDN 1 Tuntang, which has 27 students as the sample. She focuses on teaching method, which gives emphasis on flashcards as media in teaching vocabulary. To prove the success of teaching the writer compares between the result pre-test and post-test. The findings of this study showed that there are 20 students or 60 % are categorized as excellent, 15, 6 % or 3 students are as good students, 12, 5 % or 3 students are as fair, and 3, 1 % students are as poor. It means that teaching English vocabularies by using flashcards are very effective.

    The sterilising cytoplasm from Triticum timopheevii is presently considered to be the most promising as regards to the seed production of triticale hybrid cultivars. This study was aimed at the utilisation of Diversity Arrays Technology (DArT) for the preliminary identification of genomic regions with loci controlling male sterility/fertility in the field-grown F2 generation of the interline hybrid between male sterile line CMS-Salvo 15/1 and restorer line Stan I. The fertility of plants was examined by visual scoring as well as by the assessment of seed setting within bagged spikes. For DNA analyses, 92 individuals representing opposite phenotypes (male sterile vs. fully male fertile) were chosen from the whole F2 population, which consisted of 414 plants. The constructed genetic map consists of 759 DArT markers distributed in 24 linkage groups that cover a distance of 974.4 cM. Application of the interval mapping method and the Kruskal-Wallis test enabled the identification of six genomic regions engaged in the restoration of male fertility within the mapping population. The most effective restorer genes were found on chromosomes of the sixth homeologic group, i.e. on 6R (the most efficient), 6A and 6B. Additionally, linkage groups assigned to chromosomes 1BS, 3A and 3A/3B were important for the determination of male fertility.

    The ability to retrieve basic arithmetic facts from long-term memory contributes to individual and perhaps sex differences in mathematics achievement. The current study tracked the codevelopment of preference for using retrieval over other strategies to solve single-digit addition problems, independent of accuracy, and skilled use of retrieval (i.e., accuracy and reaction time [RT]) from first to sixth grades inclusive (N=311). Accurate retrieval in first grade was related to working memory capacity and intelligence, and it predicted a preference for retrieval in second grade. In later grades, the relation between skill and preference changed such that preference in one grade predicted accuracy and RT in the next grade as RT and accuracy continued to predict future gains in preference. In comparison with girls, boys had a consistent preference for retrieval over other strategies and had faster retrieval speeds, but the sex difference in retrieval accuracy varied across grades. Results indicate that ability influences early skilled retrieval, but both practice and skill influence each other in a feedback loop later in development and provide insights into the source of the sex difference in problem-solving approaches.

    2016-05-10

    The purpose of the present study was to test the efficacy of a modified cognitive strategy instructional intervention originally developed to improve the mathematical problem solving of middle and high school students with learning disabilities (LD). Fifth and sixth grade general education mathematics teachers and their students of varying ability (i.e., average-achieving [AA] students, low-achieving [LA] students, and students with LD) participated in the research study. Several features of the intervention were modified, including (a) explicitness of instruction, (b) emphasis on meta-cognition, (c) focus on problem-solving prerequisites, (d) extended duration of initial intervention, and (e) addition of visual supports. General education math teachers taught all instructional sessions to their inclusive classrooms. Curriculum-based measures (CBMs) of math problem solving were administered five times over the course of the year. A multilevel model (repeated measures nested within students and students nested within schools) was used to analyze student progress on CBMs. Though CBM scores in the intervention group were initially lower than that of the comparison group, intervention students improved significantly more in the first phase, with no differences in the second phase. Implications for instruction are discussed as well as directions for future research.

    Full Text Available Abstract This commentary paper provides a selective overview of topics addressed at the sixth annual meeting of the International Society of Behavioral Nutrition and Physical Activity (ISBNPA. With 31 symposiums, 42 free paper sessions and 236 poster presentations ISBNPA 2007 provided a comprehensive overview of the state of the art and of new avenues for behavioral nutrition and physical activity research. Research presented at the conference helps to identify and specify important nutrition and physical activity behaviors for health promotion, as well as the correlates, predictors and determinants of these behaviors, and to build and test intervention strategies that go beyond traditional health education. ISBNPA 2007 also indicates that ISBNPA should strive to become more international by inclusion of more scientists from countries outside North America, Western Europe and Australia. ISBNPA should maintain its encouragement of research that is firmly rooted in behavioral theory and research that goes beyond applying cross-sectional research designs, and that addresses the most important public health issues associated with behavioral nutrition and physical activity.

    The main focus of this article is to develop a better understanding of the developmental trajectories of literacy and phonological skills within Dutch-speaking children. Children at high and low risk for dyslexia were followed and compared at four different moments: kindergarten and first, third and sixth grades. Three groups were then compared: (1) dyslexic readers; (2) normal readers at high risk for dyslexia; and (3) normal readers at low risk for dyslexia. Children diagnosed with dyslexia scored lower than high-risk normal readers on phonological awareness (PA), rapid automatized naming (RAN), verbal short-term memory and literacy skills. Normal readers at high risk scored between both groups, confirming that dyslexia is to be considered as a continuum rather than an all-or-none condition. Growth analyses showed that the three groups evolved similarly on all measures except for phoneme deletion and literacy measures. Finally, solely PA and RAN explained a significant amount of variance in the evolution of reading skills.

    Various provocative maneuvers for diagnosing extensor carpi ulnaris (ECU) tendinitis have been reported; however, it remains unclear which maneuver is the most sensitive to detect ECU tendinitis. To clarify this, we investigated and compared the extratendinous pressure and ECU tendon strain in the sixth extensor compartment of the wrist during various provocative maneuvers for diagnosing ECU tendinitis. Nine upper extremities from nine fresh-frozen cadavers were examined. We investigated extratendinous pressure in the ECU fibro-osseous tunnel of the distal ulna and ECU tendon strain during eight forearm positions-neutral rotation, pronation, supination, pronation with wrist flexion, supination with wrist flexion, supination with wrist extension, both hand and forearm supination, and supination with ECU full loading-to simulate provocative maneuvers reported to detect ECU tendinitis. Pressure was significantly higher during both hand and forearm supination (carpal supination test) and during supination with wrist extension (prayer's hand supination test) than during neutral rotation. The pressure during the carpal supination test was 3 times higher than that during the prayer's hand supination test and 27 times higher than that during the neutral position. Strain was significantly higher during the carpal supination test and during supination with ECU full loading (the ECU synergy test) than during other maneuvers. Both pressure and tendon strain increased most notably during the carpal supination test compared to the other maneuvers, which suggests that the carpal supination test is the most sensitive for the detection of ECU tendinitis.

    The Sixth Jack Pepys Workshop on Asthma in the Workplace focused on six key themes regarding the recognition and assessment of work-related asthma and airway diseases: (1) cleaning agents and disinfectants (including in swimming pools) as irritants and sensitizers: how to evaluate types of bronchial reactions and reduce risks; (2) population-based studies of occupational obstructive diseases: use of databanks, advantages and pitfalls, what strategies to deal with biases and confounding?; (3) damp environments, dilapidated buildings, recycling processes, and molds, an increasing problem: mechanisms, how to assess causality and diagnosis; (4) diagnosis of occupational asthma and rhinitis: how useful are recombinant allergens (component-resolved diagnosis), metabolomics, and other new tests?; (5) how does exposure to gas, dust, and fumes enhance sensitization and asthma?; and (6) how to determine probability of occupational causality in chronic obstructive pulmonary disease: epidemiological and clinical, confirmation, and compensation aspects. A summary of the presentations and discussion is provided in this proceedings document. Increased knowledge has been gained in each topic over the past few years, but there remain aspects of controversy and uncertainty requiring further research.

  1. Sixth coordination meeting of the Division of Nuclear Physics Program to meet high-priority nuclear data needs of the Office of Fusion Energy

    1990-06-01

    The Sixth Coordination Meeting of the Program to Meet Nuclear Data Needs for Fusion Energy was held in Athens, September 19--21, 1989. The principal change from the previous meeting at Argonne was the larger international participation. One scientist from Japan represented the only non-US participation at Argonne. The present meeting included about 20% non-US participants. This change is a welcome one since the data needs are international and the limited availability of manpower and facilities will likely make international cooperation increasingly important in the future. The organization of the meeting involved collecting and distributing to all participants progress reports from the Department of Energy laboratories in advance of the meeting. Twenty-five oral presentations were made at the meeting, including many from non-DOE labs. The meeting then divided into experimental and theoretical task force groups, which carried out assigned agenda items. The reports of these groups, abstracts of the talks presented at the meeting, and the progress reports are included in this report. The topics discussed will be very familiar to participants in past meetings, but continued progress in most areas was reported. One discussion topic which reflects continuing and perhaps worsening problems was the aging of facilities and personnel, coupled with a lack of programs to renew.

    The American Society for Apheresis (ASFA) JCA Special Issue Writing Committee is charged with reviewing, updating and categorizating indications for therapeutic apheresis. Beginning with the 2007 ASFA Special Issue (Fourth Edition), the committee has incorporated systematic review and evidence-based approach in the grading and categorization of indications. This Sixth Edition of the ASFA Special Issue has further improved the process of using evidence-based medicine in the recommendations by consistently applying the category and GRADE system definitions, but eliminating the "level of evidence" criteria (from the University HealthCare Consortium) utilized in prior editions given redundancy between GRADE and University HealthCare Consortium systems. The general layout and concept of a fact sheet that was utilized in the Fourth and Fifth Editions, has been largely maintained in this edition. Each fact sheet succinctly summarizes the evidence for the use of therapeutic apheresis in a specific disease entity. This article consists of 78 fact sheets (increased from 2010) for therapeutic indications in ASFA categories I through IV, with many diseases categorized having multiple clinical presentations/situations which are individually graded and categorized.

    We present the largest publicly available catalogue of compact groups of galaxies identified using the original selection criteria of Hickson, selected from the Sixth Data Release (DR6) of the Sloan Digital Sky Survey (SDSS). We identify 2297 compact groups down to a limiting magnitude of r = 18 (~0.24groups degree^{-2}), and 74791 compact groups down to a limiting magnitude of r = 21 (~6.7groups degree^{-2}). This represents 0.9% of all galaxies in the SDSS DR6 at these magnitude levels. Contamination due to gross photometric errors has been removed from the bright sample of groups, and we estimate it is present in the large sample at the 14% level. Spectroscopic information is available for 4131 galaxies in the bright catalogue (43% completeness), and we find that the median redshift of these groups is z_{med} = 0.09. The median line-of-sight velocity dispersion within the compact groups from the bright catalogue is sigma_{LOS} ~ 230km/s and their typical inter-galactic separations are of order 50 - 100kpc....

    Therapeutic options for the treatment of malignant brain tumors have been limited, in part, because of the presence of the blood-brain barrier. For this reason, the Sixth Annual Meeting of the Blood-Brain Barrier Disruption Consortium, the focus of which was the "Importance of Dose Intensity in Neuro-Oncology Clinical Trials," was convened in April 2000, at Government Camp, Mount Hood, Oregon. This meeting, which was supported by the National Cancer Institute, the National Institute of Neurological Disorders and Stroke, and the National Institute of Deafness and Other Communication Disorders, brought together clinicians and basic scientists from across the U.S. to discuss the role of dose intensity and enhanced chemotherapy delivery in the treatment of malignant brain tumors and to design multicenter clinical trials. Optimizing chemotherapy delivery to the CNS is crucial, particularly in view of recent progress identifying certain brain tumors as chemosensitive. The discovery that specific constellations of genetic alterations can predict which tumors are chemoresponsive, and can therefore more accurately predict prognosis, has important implications for delivery of intensive, effective chemotherapy regimens with acceptable toxicities. This report summarizes the discussions, future directions, and key questions regarding dose-intensive treatment of primary CNS lymphoma, CNS relapse of systemic non-Hodgkin's lymphoma, anaplastic oligodendroglioma, high-grade glioma, and metastatic cancer of the brain. The promising role of cytoenhancers and chemoprotectants as part of dose-intensive regimens for chemosensitive brain tumors and development of improved gene therapies for malignant gliomas are discussed.

"nMaterials and Methods: In this study, 63 teeth of 35 students aged 6-8 with healthy and newly-erupted upper jaw molar teeth, were selected and divided into two groups. In one group, single-bond and In the other, SE bond were used. As the teeth were newly erupted and the distopalatal area being in contact with the gingival sulcus and this fact that, this area was impossible to isolate, the distal sulcus of the contaminated teeth and the mesial area capable of adequate isolation were assumed isolated. For each group, after etching, the teeth on one side were treated with a sealant and the teeth on the other side were first bonded and then treated with the sealant. Hence, four groups were formed: bonded/isolated, bonded/contaminated, controlled/isolated and controlled/contaminated for any bonding agent. The results of the treatment were assessed in terms of the success and failure and then analyzed using Mc Nemar, and Chi-square tests and Cochran. "nResults: The results of the study indicated that:1. Saliva contamination caused a significant increase in sealant failures(p<0.05.2.

    Full Text Available Incremental forming is a process to produce sheet metal parts in quick. Because there is no need for dedicated dies and molds, this process is less cost and time spent. The purpose of this study is to investigate forming forces in single point incremental forming. Producing a cone frustum of aluminum is tested for forming forces. A dynamometer is used to collect forming forces and analyze them. These forces are compared with cutting forces upon producing same geometrical shapes of experimental parts. The forming forces in Z direction are 40 times larger than the machining forces. A spindle and its axis of a forming machine should be designed enough to withstand the forming forces.

Waist-to-height ratio (WHtR does not depend on sex-and-age references. In the HEALTHY Study enrollment sample, we compared BMIz with WHtR for ability to identify adverse cardiometabolic risk. Among 5,482 sixth-grade students from 42 middle schools, we estimated explanatory variations (R2 and standardized beta coefficients of BMIz or WHtR for cardiometabolic risk factors: insulin resistance (HOMA-IR, lipids, blood pressures, and glucose. For each risk outcome variable, we prepared adjusted regression models for four subpopulations stratified by sex and high versus lower fatness. For HOMA-IR, R2 attributed to BMIz or WHtR was 19%–28% among high-fatness and 8%–13% among lower-fatness students. R2 for lipid variables was 4%–9% among high-fatness and 2%–7% among lower-fatness students. In the lower-fatness subpopulations, the standardized coefficients for total cholesterol/HDL cholesterol and triglycerides tended to be weaker for BMIz (0.13–0.20 than for WHtR (0.17–0.28. Among high-fatness students, BMIz and WHtR correlated with blood pressures for Hispanics and whites, but not black boys (systolic or girls (systolic and diastolic. In 11-12 year olds, assessments by WHtR can provide cardiometabolic risk estimates similar to conventional BMIz without requiring reference to a normative growth chart.

    An alarmingly high number of children become addicted to tobacco use. To teach children the skills to resist the influences surrounding the initiation of tobacco and other drug use, a Drug Abuse Resistance Education (D.A.R.E.) program is being implemented in three fourths of the schools in the United States. The purpose of this study is to examine the impact of this program in preventing smoking. A survey was conducted among 236 fifth and sixth graders in Nashville, Tennessee. Of the students included in the survey, 88% graduated from D.A.R.E. Approximately 11.6% of respondents had ever smoked cigarettes; 86% of them continued to smoke. The D.A.R.E. group had a significantly lower rate of smoking compared with their non-D.A.R.E. counterparts (8.7% vs. 28.0%; p = 0.0001). Logistic regression analysis shows that the D.A.R.E. group was five times (odds 4.9; p = 0.003; 95% CI: 1.7, 14.0) less likely to initiate smoking compared with the non-D.A.R.E. group. The D.A.R.E. group had a significantly (p = 0.002) higher knowledge score on the risk of smoking. The knowledge score has strong opposite correlation to smoking behavior (p = 0.00001). Students with top-quartile knowledge scores had a substantially lower rates of smoking (1.4% vs. 14.4%; p = 0.001). This finding is consistent for both African-American (0% vs. 19.6%; p = 0.001) and white children (1.9% vs. 13%; p = 0.001). The D.A.R.E. program may have an impact in preventing the initiation of smoking behavior.

    Tómatelo a Pecho, Funsalud, the Harvard Global Equity Initiative, and the Mexican Ministry of Health led a group of institutions in organising the Sixth Annual International Symposium marking breast cancer awareness month in Mexico on 20-21 October 2014. This year's event, with the theme 'Young Women and Breast Cancer: Challenges and Answers', took place at the National Institute of Perinatology in Mexico City. This was the first time the symposium focused almost entirely on young women. The reasons for this emphasis were reported on by many national and global experts, who also presented evidence to show that breast cancer has become a leading cause of death among younger women in Mexico, and conveyed the benefits of early breast cancer detection and the need to create innovative solutions for care and survivorship support for this age group. Over the course of one-and-a-half days, the symposium covered a wide range of topics and perspectives, including the epidemiology, biology, and genetics of breast cancer; challenges; and innovative answers to early detection and the myriad of short- and long-term challenges faced by patients with breast cancer, such as some cutting-edge techniques used to preserve fertility in women undergoing chemotherapy. How the presence of local and global stakeholders will ensure the accountability of the multiple participants already immersed in the various areas of research and activities related to breast cancer. The voices of the Ministry of Health and of other institutions central to the Mexican health system show that there is a political will for work in this area, and there are the means to make a change happen.

    Little is known about specific learning disorder (SLD) in low- and middle-income countries (LMICs), and even less from representative school samples in small size cities outside huge urban centers. Few studies addressed the new DSM-5 criteria for SLDs. We investigated the prevalence of DSM-5 SLDs, their comorbidities and correlates in school samples of students from the second to sixth grades living in median cities from four different geographic regions in Brazil. A national test for academic performance covering reading, writing and mathematical abilities was applied. Psychiatric diagnoses were assessed by the K-SADS-PL applied to the primary caregiver. A total of 1618 children and adolescents were included in the study. The following prevalence rates of SLDs were found: 7.6% for global impairment, 5.4% for writing, 6.0% for arithmetic, and 7.5% for reading impairment. Attention-deficit/hyperactivity disorder (ADHD) was the only comorbidity significantly associated with SLD with global impairment (p = 0.031). Anxiety disorders and ADHD were associated with SLD with arithmetic impairment. Significant differences were detected in prevalence rates among cities, and several socio-demographic correlates (age, gender, IQ, and socioeconomic status) were significantly associated with SLD with global impairment in our sample. Careful validation and normatization of instruments to assess academic performance is a major problem in LMICs. As expected, we found a significant heterogeneity in prevalence rates of SLD according to geographic regions considering that Brazil is a country with a robust diversity. SLD with global and arithmetic impairment was significantly associated with psychiatric comorbidities.

    The sixth cervical vertebra (C6) has unique morphology due to a ventral extension from the transverse process known as the ventral lamina. Little information was found regarding the prevalence and clinical relevance of morphologic variations. Aims of this observational, retrospective study were to characterize C6 morphologic variations in a large sample of horses. Cervical radiographic studies of 100 horses were retrieved. Data recorded were signalment, clinical history, morphology of the C6 ventral lamina, presence of articular process osteoarthritis, and presence of static vertebral canal stenosis. Morphologic variations were found in C6 vertebrae for 24/100 horses, with symmetric absence of the ventral lamina in nine horses and asymmetric absence in 15. Anomalous C6 vertebrae were more common in Warmbloods, with 19/55 Warmbloods in the population being affected (P = 0.006). No association was found with sex. There was no significant difference in the mean of the intravertebral sagittal ratios between horses with normal or anomalous C6 vertebrae; however there was a significantly greater proportion of horses with anomalous C6 vertebrae that had an intravertebral sagittal ratio of less than 0.5 at C6 (P = 0.047). There was no association between the morphology of C6 and articular process osteoarthritis. Anomalous C6 vertebrae in our population were associated with a higher likelihood of cervical pain (P = 0.013). Authors propose that morphologic variations in the C6 ventral laminae could be linked to other developmental abnormalities such as vertebral canal stenosis, might affect regional biomechanics and should therefore be considered clinically relevant in horses. Future, controlled prospective studies are needed to test this theory.

    2008-01-01

    Special p-forms are forms which have components \\phi_{\\mu_1...\\mu_p} equal to +1,-1 or 0 in some orthonormal basis. A p-form \\phi\\in \\Lambda^p R^d is called democratic if the set of nonzero components {\\phi_{\\mu_1...\\mu_p}} is symmetric under the transitive action of a subgroup of O(d,Z) on the indices {1,...,d}. Knowledge of these symmetry groups allows us to define mappings of special democratic p-forms in d dimensions to special democratic P-forms in D dimensions for successively higher P \\geq p and D \\geq d. In particular, we display a remarkable nested stucture of special forms including a U(3)-invariant 2-form in six dimensions, a G_2-invariant 3-form in seven dimensions, a Spin(7)-invariant 4-form in eight dimensions and a special democratic 6-form \\Omega in ten dimensions. The latter has the remarkable property that its contraction with one of five distinct bivectors, yields, in the orthogonal eight dimensions, the Spin(7)-invariant 4-form. We discuss various properties of this ten dimensional form.

    2012-01-01

    FORM, a symbolic manipulation system, has been widely used in a lot of calculations for High Energy Physics due to its high performance and fficient design. Mathematica, another computational software program, has also widely been used, but more for reasons of generality and user-friendliness than for speed. Especially calculations involving tensors and noncommutative operations like calculating Dirac traces can be rather slow in Mathematica, compared to FORM. In this article we describe FormLink and FeynCalcFormLink, two Mathematica packages to link Mathematica and FeynCalc with FORM. FormLink can be used without FeynCalc and FeynCalcFormLink, which is an extension loading FormLink and FeynCalc automatically. With these two packages the impressive speed and other special features of FORM get embedded into the generality of Mathematica and FeynCalc in a simple manner. FeynCalcFormLink provides a FORM-based turbo for FeynCalc, making it much more efficient. FormLink turns Mathematica into an editor and code or...

  5. The semantics of biological forms.

    Albertazzi, Liliana; Canal, Luisa; Dadam, James; Micciolo, Rocco

    2014-01-01

    This study analyses how certain qualitative perceptual appearances of biological forms are correlated with expressions of natural language. Making use of the Osgood semantic differential, we presented the subjects with 32 drawings of biological forms and a list of 10 pairs of connotative adjectives to be put in correlations with them merely by subjective judgments. The principal components analysis made it possible to group the semantics of forms according to two distinct axes of variability: harmony and dynamicity. Specifically, the nonspiculed, nonholed, and flat forms were perceived as harmonic and static; the rounded ones were harmonic and dynamic. The elongated forms were somewhat disharmonious and somewhat static. The results suggest the existence in the general population of a correspondence between perceptual and semantic processes, and of a nonsymbolic relation between visual forms and their adjectival expressions in natural language.

    2015-01-01

    Interaction design is distinguished from most other design disciplines through its temporal form. Temporal form is the computational structure that enables and demands a temporal expression in the resulting design. Temporal form is what enables poetry. In music, temporal form is the composition...... of tones, pauses, and timbre arranged into harmonies and rhythms. In interaction design it is, for instance, the behaviors of pixels on a screen or the movements in shape-changing interfaces. In this paper we show the power of working explicitly with temporal form in designing computational things. We give...... temporal forms by letting a series of expert designers reflect upon them. We borrow a framework from Boorstin’s film theory in which he distinguishes between the voyeuristic, the vicarious, and the visceral experience. We show how to use rhythms, complexity, gentle or forceful behavior, etc., to create...

    A broad program measuring parity-violation in electron-nuclear scattering has now provided a large set of precision data on the weak-neutral-current form-factors of the proton. Under comparison with well-measured electromagnetic nucleon form-factors, these measurements reveal the role of the strange quark sea on the low-energy interactions of the proton through the strange-quark-flavor vector form-factors. This review will describe the experimental program and the implications of the global data for the strange-quark vector form-factors. We present here a new fit to the world data.

    Urogenital tuberculosis is an increasingly frequent serious disease. The diagnosis is often delayed due to the marked clinical polymorphism, leading to serious sequelae. The diagnosis of typical forms is easy, but some forms are misleading and can lead to an incorrect diagnosis. The authors report a pseudoneoplastic form of urogenital tuberculosis in a young patient that was initially diagnosed as lymphoma. In the light of this case and a review of the literature, the authors emphasize the diagnostic difficulties of these forms and the treatment modalities.

    Full Text Available The study was conducted by method of light scattering of laser emission. The influence of the form field, mutual influence of mental informational and form torsional fields as well as the following exposure of water samples in the form field after the cease of informational influence on water structure were examined. Paper forms of a pyramid, a cylinder, and a prism were used. The experimental findings show that mechanism of mutual influence on water structure of the form and informational torsional fields depended on the initial conditions of spin restructuring process – the configuration of a form, the type of the form field (internal and external ones, and the initial water structure. The influence of the form field on informational aftereffect was determined, the character of which was defined by ratio of intensities of torsional form field and an informational soliton. The phenomenon of the abnormally large amplification of the informational aftereffect in the internal field of a pyramid demonstrating the attributes of positive reverse connection between the informational soliton and torsional field of water structure and selection of generated cluster sizes were discovered.

    Limited or no literature exists identifying factors associated with functional nerve recovery in patients undergoing resection of sixth cranial nerve (CN VI) schwannomas. A systematic review of literature was performed on CN VI schwannomas that were treated surgically. Synthesizing the findings pooled from the literature, we investigated associations of patient demographics and clinical characteristics with postsurgical CN VI functional recovery in multivariable regression models. In addition, we present the findings of an adolescent woman surgically managed for intracavernous CN VI schwannoma. Complete encasement of the cavernous segment of the internal carotid artery is unique to our case. We synthesized data of 32 patients from 29 studies, and our index case. Overall, the mean age of the patients was 44.0 ± 16.5 years, and approximately 52% (n = 17) were female. Most tumors were left-sided (n = 18; 54.5%), with an average size of 3.46 ± 1.71 cm. The most common location was cisternal (n = 11; 33%), followed by cavernous sinus (CS) proper (n = 9; 27%), cisterocavernous (n = 8; 24%), orbital (n = 4; 12%) and caverno-orbital (n = 1; 3%). CN VI recovery was reported in less than half the cohort (n = 14; 45%). Tumor extension in the CS was significantly associated with lesser likelihood (odds ratio [OR], 0.07; 95% confidence interval [CI], 0.01-0.98; P = 0.048) of postsurgical CN VI recovery. Although female gender (OR, 0.86; 95% CI, 0.07-10.09; P = 0.906), large tumor size (>2.5 cm) (OR, 0.45; 95% CI, 0.07-2.89; P = 0.397), and solid consistency (OR, 0.37; 95% CI, 0.03-4.19; P = 0.421) were associated with lesser odds for recovery, these were not statistically significant. Likewise, although gross total resection (OR, 6.28; 95% CI, 0.33-118.25; P = 0.220) was associated with higher odds of nerve recovery, the estimates were statistically insignificant. CS involvement is associated with lesser odds for functional nerve recovery in patients undergoing

  19. A content analysis of sixth-grade, seventh-grade, and eighth-grade science textbooks with regard to the nature of science

    Science.gov (United States)

    Phillips, Marianne C.

    Science teachers rely heavily on their textbooks; for many, it is the only curriculum they use (Weiss, 1993). Therefore, it is important these materials convey an accurate conception of the nature of science. Science for All Americans (AAAS, 1990) and the National Science Education Standards (NRC, 1996) call for teaching students about the nature of science. Including the nature of science throughout science textbooks will produce scientifically literate citizens (Driver and others, 1993) with an improved ability to make informed decisions (McComas, 1998). Teaching the nature of science supports the successful learning of science content and process (Driver and others, 1996), and bridges the gap between the two cultures of practicing scientists and school science (Sorsby, 2000). Do middle school science textbooks provide a balanced presentation of the nature of science throughout their text? To determine the answer, this investigation used a content analysis technique to analyze a random sample from the introduction chapter and the rest of the textbook chapters from twelve middle school science textbooks for the four aspects of the nature of science (Chiappetta, Fillman, & Sethna, 2004). Scoring procedures were used to determine interrater agreement using both Cohen's kappa (kappa) and Krippendorff's alpha (alpha). Kappa values were determined to be fair to excellent beyond chance among the three coders. The resulting values for Krippendorff's alpha ranged from acceptable (alpha > .80) to unacceptable (alpha < .67). The results from this content analysis indicated little change from previous studies in the balance for the themes of the nature of science. This investigation found the sixth-grade, seventh-grade, and eighth-grade science textbooks adopted by Texas to have unbalanced presentations for the four aspects of the nature of science. In addition, it found these middle school science textbooks are not balanced across programs. This imbalance is providing

  4. Quantum modular forms, mock modular forms, and partial theta functions

    Science.gov (United States)

    Kimport, Susanna

    Defined by Zagier in 2010, quantum modular forms have been the subject of an explosion of recent research. Many of these results are aimed at discovering examples of these functions, which are defined on the rational numbers and have "nice" modularity properties. Though the subject is in its early stages, numerous results (including Zagier's original examples) show these objects naturally arising from many areas of mathematics as limits of other modular-like functions. One such family of examples is due to Folsom, Ono, and Rhoades, who connected these new objects to partial theta functions (introduced by Rogers in 1917) and mock modular forms (about which there is a rich theory, whose origins date back to Ramanujan in 1920). In this thesis, we build off of the work of Folsom, Ono, and Rhoades by providing an infinite family of quantum modular forms of arbitrary positive half-integral weight. Further, this family of quantum modular forms "glues" mock modular forms to partial theta functions and is constructed from a so-called "universal" mock theta function by extending a method of Eichler and Zagier (originally defined for holomorphic Jacobi forms) into a non-holomorphic setting. In addition to the infinite family, we explore the weight 1/2 and 3/2 functions in more depth. For both of these weights, we are able to explicitly write down the quantum modular form, as well as the corresponding "errors to modularity," which can be shown to be Mordell integrals of specific theta functions and, as a consequence, are real-analytic functions. Finally, we turn our attention to the partial theta functions associated with these low weight examples. Berndt and Kim provide asymptotic expansions for a certain class of partial theta functions as q approaches 1 radially within the unit disk. Here, we extend this work to not only obtain asymptotic expansions for this class of functions as q approaches any root of unity, but also for a certain class of derivatives of these functions

    Electron spin resonance (ESR) experiments have been carried out in single crystals of the unfilled skutterudite CoSb3 doped with Er ions. The X- (9.5 GHz) and Q- (34.4 GHz) band spectra obtained at low temperature (4-20 K) shown a temperature independent g-value of 6.21(5). This g-value can only be explained with the addition of a second sixth order B6t(O62-O66) term to the usual cubic crystal field Hamiltonian. The ESR of Er show the typical temperature dependence of the line-shape and line-width expected for insulating host.

    Integral forms provide a natural and powerful tool for the construction of supergravity actions. They are generalizations of usual differential forms and are needed for a consistent theory of integration on supermanifolds. The group geometrical approach to supergravity and its variational principle are reformulated and clarified in this language. Central in our analysis is the Poincaré dual of a bosonic manifold embedded into a supermanifold. Finally, using integral forms we provide a proof of Gates' so-called "Ectoplasmic Integration Theorem", relating superfield actions to component actions.

    Single point incremental forming (SPIF) is a well known process which is used for rapid prototyping or for small-quantity production. The feature of this process is the flexible manufacturing of complex hollow shapes with the use of basic equipments. However, this forming process takes very long time. To speed up the process time, multiple forming tools can be used simultaneously. This paper presents the influence of the multiple tools in SPIF on the formed shape. The conventional SPIF with a single tool is taken into account for a comparative analysis. The results in this study showed that the tool arrangements and its distance have a significant effect on the geometrical accuracy. Moreover, it is shown the influence between the vertical step size of the tool and the strain distributions. This knowledge can be used for generation of new forming strategies.

    This paper presents the good practice based experiences found when movement is used to strengthen form creation and to create flow in the process of artistic education. Faced with the design engineering students’ problems with creating forms with aesthetic statements, the experiences with movement...... inspired the thesis that the design engineers’ training in aesthetic form creation can be improved by integrating the movement potential into their education. The paper documents the on-going work on developing a model for embodied creation of form called ‘Somatechne model’. The study also identifies...... a lens to assess the students’ development of mind-body skills, known as ‘The Three Soma’. The Somatechne model also helps to identify the activity that gives the students the opportunity to develop their sensibility and thus aesthetic attention....

    Abraham Lempel et al[1] made a connection between linear codes and systems of bilinear forms over finite fields. In this correspondence, a new simple proof of a theorem in [1] is presented; in addition, the encoding process and the decoding procedure of RS codes are simplified via circulant matrices. Finally, the results show that the correspondence between bilinear forms and linear codes is not unique.
