Cultural Astronomy in Elementary and Secondary School
Jafelice, Luiz Carlos
2015-07-01
This work is addressed to educators and geography, science, biology and physics teachers who deal with elementary, middle and high school education. It discusses the importance of adopting the anthropological perspective regarding issues that are considered within the astronomy area. It also presents practical proposals for those who intend to introduce cultural astronomy in elementary, middle and high school education - from the beginning of the 1st grade in Elementary school to the end of the 3rd grade in Secondary school, in formal as well as in informal education. This work is proposed within the context of the holistic and transdisciplinary environmental education. Our approach values above all the experience and aims at a humanistic education that includes epistemological and cultural diversities. The suggested practical proposals can be also beneficially used to address works that include contents related to Brazilian indigenous and Afro-descent cultures in the school curriculum, as the new law requires. The guidelines presented here were tested in real school situations.

Secondary School Department Chairs Leading Successful Change
Directory of Open Access Journals (Sweden)
Julie Ann Gaubatz
2015-12-01
Full Text Available A foundational understanding within education leadership literature is that education leaders are expected to guide reform efforts within school. This expectation mirrors organizational development literature that describes leaders as individuals who constructively institute change within their organizations. Although leadership and change are portrayed as codependent, no scholarship has linked change models with leadership theories. This article describes a multiple case study that explored the relationship between leadership behaviors and the change process through secondary school department chair stories of change. From this analysis, a clearer picture emerged that illustrates how leaders with little control over decisions implement change. Findings included distinct connections between CREATER change process stages and the Leadership Grid. Suggestions as to how education leaders should approach change attempts within their schools are discussed.
Holocaust Studies in Austrian Elementary and Secondary Schools
Directory of Open Access Journals (Sweden)
Philipp Mittnik
2016-09-01
Full Text Available This article presents arguments in support of teaching about the Holocaust and Nazism in Austria at an early age. To accomplish this, Austrian and German elementary school textbooks were analyzed for the amount of content dealing with the Holocaust and Jews; the results showed that since 1980 the amount of content on the Holocaust increased in Germany, and to a lesser extent in Austria. The article reviews some of the criticism in Europe of the term Holocaust Education and explores some of arguments about why that is. The author argues that moral education and teaching of Human Rights are important components of, but ought not be the main goal of teaching about the Holocaust. The role of Austria after World War II, and exploration of the so called victim myth, prevalent until the 1990s are important to understanding history and to how history textbooks were created. After a discussion of how the Holocaust can be taught to elementary and early secondary school aged children, some suggestions are made about approaches to teaching the Holocaust to students in these age groups.
Prospective elementary and secondary school mathematics teachers’ statistical reasoning
Directory of Open Access Journals (Sweden)
Rabia KARATOPRAK
2015-04-01
Full Text Available This study investigated prospective elementary (PEMTs and secondary (PSMTs school mathematics teachers’ statistical reasoning. The study began with the adaptation of the Statistical Reasoning Assessment (Garfield, 2003 test. Then, the test was administered to 82 PEMTs and 91 PSMTs in a metropolitan city of Turkey. Results showed that both groups were equally successful in understanding independence, and understanding importance of large samples. However, results from selecting appropriate measures of center together with the misconceptions assessing the same subscales showed that both groups selected mode rather than mean as an appropriate average. This suggested their lack of attention to the categorical and interval/ratio variables while examining data. Similarly, both groups were successful in interpreting and computing probability; however, they had equiprobability bias, law of small numbers and representativeness misconceptions. The results imply a change in some questions in the Statistical Reasoning Assessment test and that teacher training programs should include statistics courses focusing on studying characteristics of samples.

Strategies for Astronomers in the Preparation of Pre-Service Elementary and Secondary Teachers
Schultz, G. R.
2004-12-01
Making an impact on pre-service teacher preparation is challenging and requires a multi-faceted approach. To begin with, it's advisable to be informed by the education research and consensus policy statements published by the teacher education community, and to make meaningful connections with educators in this field. Two significant books to consult in this area come from the National Academy Press: "How People Learn: Brain, Mind, Experience, and School" (NRC, 2000; see in particular chapter 8 on 'Teacher Learning') and "Educating Teachers of Science, Mathematics, and Technology: New Practices for the New Millennium" (NRC, 2001). Much can also be learned from joining the Association for the Education Teachers of Science (AETS; www.TheAETS.org) and/or attending its annual conferences, which attract various science teacher educators. It goes without saying that most teachers tend to teach science the way they learned it themselves, at least as a "default" pedagogical approach. Thus, initiatives in pre-service teacher preparation should include efforts to involve constructivist, inquiry-based teaching and learning in the undergraduate science lecture and laboratory courses that future teachers are enrolling in. Another important area in teacher education is the "science methods" course that a pre-service teacher enrolls in, through a college or school of education. Science methods courses are usually offered in both elementary and secondary education, and the approaches in each are of course different. Pre-service teachers in methods courses are often most concerned with classroom management strategies, and there is usually not much time in these courses for guidance on astronomy-specific (or any discipline-specific) curriculum and instruction. But experiences with short "interventions" in both elementary and secondary science methods courses have demonstrated that talking about and working hands-on with a well-designed space science curriculum resource (e.g. "The

Schools present highly desirable marketing environments for food and beverage companies. However, most marketed items are nutritionally poor. To examine national trends in student exposure to selected school-based commercialism measures from 2007 through 2012. Annual nationally representative cross-sectional studies were evaluated in US public elementary, middle, and high schools with use of a survey of school administrators. School-based commercialism, including exclusive beverage contracts and associated incentives, profits, and advertising; corporate food vending and associated incentives and profits; posters/advertisements for soft drinks, fast food, or candy; use of food coupons as incentives; event sponsorships; and fast food available to students. Changes over time in school-based commercialism as well as differences by student body racial/ethnic distribution and socioeconomic status. Although some commercialism measures-especially those related to beverage vending-have shown significant decreases over time, most students at all academic levels continued to attend schools with one or more types of school-based commercialism in 2012. Overall, exposure to school-based commercialism increased significantly with grade level. For 63.7% of elementary school students, the most frequent type of commercialism was food coupons used as incentives. For secondary students, the type of commercialism most prevalent in schools was exclusive beverage contracts, which were in place in schools attended by 49.5% of middle school students and 69.8% of high school students. Exposure to elementary school coupons, as well as middle and high school exclusive beverage contracts, was significantly more likely for students attending schools with mid or low (vs high) student body socioeconomic status. Most US elementary, middle, and high school students attend schools where they are exposed to commercial efforts aimed at obtaining food or beverage sales or developing brand recognition

The aim of the study was to examine the effectiveness of the smoking prevention program "I do not smoke, I exercise" implemented with elementary and secondary school students. "I do not smoke, I exercise" is a theory-based smoking prevention program that promotes exercise as an alternative of smoking. The program consists of eight sessions implemented weekly. Participants were 338 Greek students (135 elementary and 203 secondary students) who were pre- and posttested in smoking, program, and exercise-related measures. The results showed that the program had significant effects on elementary students' attitudes toward smoking, intention to smoke, subjective norms, attitudes toward the application of the program, and knowledge about the health consequences of smoking. For secondary students, significant effects were found on students' perceived behavioral control and knowledge about the health consequences of smoking, while very few students reported a smoking experience before and after the intervention. Therefore the program "I do not smoke, I exercise" may have positive effects on variables related with smoking behavior. Differences in the program's impact on elementary and secondary students were identified. All these are discussed with reference to the need of implementing smoking prevention programs in schools contexts. © 2016 Society for Public Health Education.

The present invention relates to a method of chemical and elementary analysis of samples through a spectral analysis of secondary electrons (Auger electrons) emitted from said sample under a primary monokinetic electron beam concentrated on its surface. Said method is characterized in that the intensity of the primary monokinetic electron beam emitted from an electron gun is modulated at a frequency ω; and in that the secondary electrons of energy E emitted from the sample are then collected. A reference voltage corresponding to the modulation in intensity of the primary electron beam is applied at the input of a phase sensitive detector together with a voltage proportional to the intensity of the flux of said collected secondary electrons to obtain at the output of said detector a voltage proportional to the number of the secondary electrons of energy E. The secondary emission energy spectrum of the sample is then plotted [fr

Specificity of radionuclide distribution in elementary landscape geochemical systems (ELGS) treated as local system of geochemically linked elementary terrestrial units (in toposequence: watershed-slope-closing depression), belongs to one of the less investigated but practically significant problems of current geochemistry. First measurements after the Chernobyl accident showed a considerable variation of Cs-137 distribution in all examined ELGS (Shcheglov et al, 2001; Romanov, 1989; Korobova, Korovaykov, 1990; Linnik, 2008). The results may be interpreted in frames of two alternative hypotheses: 1) irregularity of the initial contamination; 2) secondary redistribution of the initially regular level of fallout. But herewith only a disproof of the first hypothesis automatically justifies the second one. Factors responsible for initial irregularity of surface contamination included: 1) the presence of the so-called "hot" particles in the initial fallout; 2) interception of radionuclides by forest canopy; 3) irregular aerial particles deposition; 4) uneven initial precipitation. Basing on monitoring Cs-137 spatial distribution that has been performed since 2005, we demonstrate that the observed spatial irregularity in distribution of Cs-137 in ELGS reflects a purely secondary distribution of initial reserves of radionuclides in fallout matter due to its migration with water in local geochemical systems. This statement has some significant consequences. 1. Mechanism of migration of matter in ELGS is complicated and could not be reduced solely to a primitive moving from watershed to closing depression. 2. The control of migration of "labeled atoms" (Cs-137) permits to understand common mechanism of migration of water in all systems on the level of ELGS. 3. Understanding formation of the structure of contamination zones in ELGS permits to use mathematical model to solve the inverse problem of restoration of the initially equable level of their contamination.

Cutaneous abscesses have traditionally been treated with incision and drainage (I&D) and left to heal by secondary closure. The objective was to compare the healing rates of cutaneous abscesses following I&D after primary or secondary closure. This was a randomized, controlled, trial, balanced by center, with blocked randomization created by a random-number generator. One urban and one suburban academic emergency department (ED) participated. Subjects were randomized to primary or secondary wound closure following I&D of the abscess. Main outcome measures were the percentage of healed wounds (wound was completely closed by visual inspection; a 40% difference in wound healing was sought) and overall failure rate (need for additional intervention including suture removal, additional drainage, antibiotics, or admission within 7 days after drainage). Fifty-six adult patients with simple localized cutaneous abscesses were included; 29 were randomized to primary closure, and 27 were randomized to secondary closure. Healing rates at 7 days were similar between the primary and secondary closure groups (69.6%, 95% confidence interval [CI] = 49.1% to 84.4% vs. 59.3%, 95% CI = 40.7% to 75.5%; difference 10.3%, 95% CI = -15.8% to 34.1%). Overall failure rates at 7 days were also similar between the primary and secondary closure groups (30.4%, 95% CI = 15.6% to 50.9% vs. 28.6%, 95% CI = 15.2% to 47.1%; difference 1.8%, 95% CI = -24.2% to 28.8%). The rates of wound healing and treatment failure following I&D of simple abscesses in the ED are similar after primary or secondary closure. The authors did not detect a difference of at least 40% in healing rates between primary and secondary closure. © 2013 by the Society for Academic Emergency Medicine.

It has been a long time since a necessity to deepen education concerning energy, in particular, nuclear-related education in the elementary and secondary education curriculums in Japan was pointed out. To attain this objective, the nuclear industry and the education industry should work in close cooperation. As the Ministry of Education's Course of Study substantially regulates the direction of school education in Japan, nuclear energy experts should be involved in its development from an early stage in an appropriate manner. At least, training for the teaching profession for science teachers should include experiments related to nuclear energy and radiation. It is considered quite effective to provide incumbent teachers with various training opportunities by nuclear organizations in order to solve the problem in question. (author)

Lipids have important functions in the human body, but high serum cholesterol level is an important risk factor for cardiovascular and cerebrovascular diseases. Prevention of stroke includes modifying risk factors, like dyslipidemias. Based on this theory, we examined in practice the possible role of a public care neurology and stroke department with a large patient turnover in vascular risk screening with regard to the diagnosis of hyperlipidemia. We reviewed all the medical records (irrespective of disease group;) of patients hospitalized in 2007 at Department of Neurclogy and Stroke Center of Szent János Hospital of the Municipality of the City of Budapest. Patients included in the study were classified into three groups: (1) those admitted with acute stroke; (2) those with a history of acute stroke, but without evidence of a novel cerebrovascular event; (3) no history and evidence of cerebrovascular disease during hospitalization. Our data show that 17.6% of patients was diagnosed with hyperlipidemia during hospital care, and another 18.5% was known to have elevated cholesterol levels. Altogether, 36.1% of the 1438 patients evaluated had hyper ipidemia. Known hypercholesterolemia was 18.4% in patierts admitted for acute stroke, 26.9% in patients formerly (but not currently) treated for cerebrovascular disease, and 13.6% in the third group. Newly diagnosed elevated cholesterol levels had highest rate (22.6%) in former stroke patierts (currently treated for other diseases); 20.4% in patients with acute stroke, and 13.2% in the third group. In the first two groups, the number of patients newly diagnosed with elevated serum cholesterol almost equaled to those with already known hypercholesterolemia. Based on our data, neurology departments have an important role in diagnosing hyperlipidemia and vascular prevention.

The aim of this study was to investigate the suitability of existing definitions of ambulatory care sensitive conditions (ACSC) in the setting of an emergency department (ED) by assessing ACSC prevalence in patients admitted to hospital after their ED stay. The secondary aim was to identify ACSC suitable for specific application in the ED setting. Observational clinical study with secondary health data. Two EDs of the Charité-Universitätsmedizin Berlin. All medical ED patients of the 'The Charité Emergency Medicine Study' (CHARITEM) study, who were admitted as inpatients during the 1-year study period (n=13 536). Prevalence of ACSC. Prevalence of ACSC in the study population differed significantly depending on the respective ACSC set used. Prevalence ranged between 19.1% (95% CI 18.4% to 19.8%; n=2586) using the definition by Albrecht et al and 36.6% (95% CI 35.8% to 37.5%; n=4960) using the definition of Naumann et al . (pdefinitions) was 48.1% (95% CI 47.2% to 48.9%; n=6505). Some frequently observed diagnoses such as ' convulsion and epilepsy ' (prevalence: 3.4%, 95% CI 3.1% to 3.7%; n=455), ' diseases of the urinary system ' (prevalence: 1.4%; 95% CI 1.2% to 1.6%; n=191) or ' atrial fibrillation and flutter ' (prevalence: 1.0%, 95% CI 0.8% to 1.2%, n=134) are not included in all of the current ACSC definitions. The results highlight the need for an optimised, ED-specific ACSC definition. Particular ACSC diagnoses (such as ' convulsion and epilepsy ' or ' diseases of the urinary system ' and others) seem to be of special relevance in an ED population but are not included in all available ACSC definitions. Further research towards the development of a suitable and specific ACSC definition for research in the ED setting seems warranted.

Elementary operators - still not elementary?

Full Text Available Properties of elementary operators, that is, finite sums of two-sided multiplications on a Banach algebra, have been studied under a vast variety of aspects by numerous authors. In this paper we review recent advances in a new direction that seems not to have been explored before: the question when an elementary operator is spectrally bounded or spectrally isometric. As with other investigations, a number of subtleties occur which show that elementary operators are still not elementary to handle.

The main goal of this research study was to develop and validate a three-tier diagnostic test to determine pre-service teachers' (PSTs) conceptual knowledge of the water cycle. For a three-tier diagnostic test, the first tier assesses content knowledge; in the second tier, a reason is selected for the content answer; and the third tier allows test-takers to select how confident they are in their answers for the first two tiers. The second goal of this study was to diagnose any alternative conceptions PSTs might have about the water cycle. The Water Cycle Diagnostic Test (WCDT) was developed using the theoretical framework by Treagust (1986, 1988, and 1995), and in similar studies that developed diagnostic tests (e.g., Calean & Subramaniam, 2010a; Odom & Barrow, 2007; Pesman & Eryilmaz, 2010). The final instrument consisted of 15 items along with a demographic survey that examined PSTs' weather-related experiences that may or may not have affected the PSTs' understanding of the water cycle. The WCDT was administered to 77 PSTs enrolled in science methods courses during the fall of 2012. Among the 77 participants, 37 of the PSTs were enrolled in elementary education (EPST) and 40 in secondary science (SPST). Using exploratory factor analysis, five categories were factored out for the WCDT: Phase Change of Water; Condensation and Storage; Clouds; Global Climate Change; and Movement through the Water Cycle. Analysis of the PSTs' responses demonstrated acceptable reliability (alpha = 0.62) for the instrument, and acceptable difficulty indices and discrimination indices for 12 of the items. Analysis indicated that the majority of the PSTs had a limited understanding of the water cycle. Of the PSTs sampled, SPSTs were significantly more confident in their answers' on the WCDT than the EPSTs. Completion of an undergraduate atmospheric science and/or meteorology course, as well as a higher interest in listening and/or viewing weather-related programs, resulted in PSTs

Presentation at an accident and emergency (A&E) department is a key opportunity to engage with a young person who self-harms. The needs of this vulnerable group and their fears about presenting to healthcare services, including A&E, are poorly understood. To examine young people's perceptions of A&E treatment following self-harm and their views on what constitutes a positive clinical encounter. Secondary analysis of qualitative data from an experimental online discussion forum. Threads selected for secondary analysis represent the views of 31 young people aged 16-25 with experience of self-harm. Participants reported avoiding A&E whenever possible, based on their own and others' previous poor experiences. When forced to seek emergency care, they did so with feelings of shame and unworthiness. These feelings were reinforced when they received what they perceived as punitive treatment from A&E staff, perpetuating a cycle of shame, avoidance and further self-harm. Positive encounters were those in which they received 'treatment as usual', i.e. non-discriminatory care, delivered with kindness, which had the potential to challenge negative self-evaluation and break the cycle. The clinical needs of young people who self-harm continue to demand urgent attention. Further hypothesis testing and trials of different models of care delivery for this vulnerable group are warranted. © The Royal College of Psychiatrists 2016.

Following the Fukushima Nuclear Power Plant accident, the Japanese government created two supplemental texts about radiation reflecting the accident for elementary, middle school, and high school students. These texts were made to explain radiation and consequently to obtain public consent for the continuation of the nuclear program. The present study aimed to evaluate the appropriateness of the content of the texts and to collect the basic data on the level of understanding necessary to improve radiation education. Lectures on radiology including nuclear energy and the Fukushima accident were given to 44 fourth-year dental students in 2013. The questionnaire was administered in 2014 when these students were in their sixth-year. The survey was also administered to 40 first-year students and 41 fourth-year students who hadn't any radiology lectures. Students rated their level of understanding of 50 phrases used in the texts on a four-point scale (understanding = 3, a little knowledge = 2, having heard = 1, no knowledge = 0). Questions on taking an advanced physics course in high school and means of learning about radiation in daily life were also asked. The level of understanding of phrases in the supplemental text for middle and high school students was significantly higher among sixth-year students (mean = 1.43) than among first-year (mean = 1.12) or fourth-year (mean = 0.93) students (p radiation from television but four-year and six-year students learning about radiation from newspaper scored significantly higher (p radiation education should be improved by using visual material and preparing educators to teach the material for improving the public's understanding of radiation use-especially nuclear power generation because the phrases used in the supplementary texts are very difficult for students to understand.

Two previous monographs report on investigations into the extent to which a unified field theory can satisfactorily describe physical reality. The first, Unified field Theory, showed that the paths within a non-Riemannian space are governed by eigenvalue equations. The second, Fundamental Constants, show that the field tensors satisfy sets of differential equations with solutions which represent the evolution of the fields along the paths of the space. The results from the first two monographs are used in this one to make progress on the theory of elementary particles. The five chapters are as follows - Quantum mechanics, gravitation and electromagnetism are aspects of the Unified theory; the fields inside the particle; the quadratic and linear theories; the calculation of the eigenvalues and elementary particles as stable configurations of interacting fields. It is shown that it is possible to construct an internal structure theory for elementary particles. The theory lies within the framework of Einstein's programme-to identify physical reality with a specified geometrical structure. (U.K.)

Overall, the level of understanding was low, with scores indicating that most students knew only a little. First-year students learning about radiation from television but four-year and six-year students learning about radiation from newspaper scored significantly higher (p < 0.05). It was concluded that radiation education should be improved by using visual material and preparing educators to teach the material for improving the public's understanding of radiation use—especially nuclear power generation because the phrases used in the supplementary

The use of emergency departments in German hospitals has been increasing in recent years. Emergency care provided by primary care services ("Bereitschaftsdienstpraxis") or a hospital emergency departments (EDs) is the subject of current discussions. The purpose of this study was to determine the reasons that outpatients with lower treatment urgency consult the ED. Further, the effects of the cooperation between primary care services and the ED will be examined. The study was an exploratory secondary data analysis of data from the hospital information system and a quality management survey of a basic and standard care clinic in a rural area. All patients classified as 4 and 5 according to the emergency severity index (ESI), both four weeks before and after the primary care services and ED visit, were included in the study. During the two survey periods, a total of 1565 outpatient cases were treated, of which 962 cases (61%) were triaged ESI 4 or 5. Of these patients, 324 were surveyed (34%). Overall, 276 cases (85%) visited the ED without contacting a physician beforehand, 161 of the cases (50%) reported an emergency as the reason. In 126 cases (39%) the symptoms lasted more than one day. One-third of all outpatient admissions (537 cases, 34%) visited the ED during the opening hours of the general practitioner. More than 80% of the surviving cases visited the ED without physician contact beforehand. The most common reason for attending the ED was, "It is an emergency." The targeted control of the patients by integrating the primary care service into the ED does not lead to an increased number of cases in the primary care service, but to a subjective relief of the ED staff.

Full Text Available Neste artigo apresenta-se o relato sobre duas pesquisas que buscaram investigar como os alunos do ensino fundamental e médio de escolas públicas e particulares do município de Presidente Prudente representam situações de injustiça na escola, bem como seus agentes e os tipos de ações que cometem. Dois conjuntos de dados foram analisados: 1 respostas obtidas por meio de questões abertas incluídas num questionário aplicado em 480 alunos em 1999, em alunos da 8ª série do ensino fundamental e 1ª série do ensino médio, nas quais foram selecionadas, para análise, as respostas que tivessem a escola como local de injustiça; 2 respostas de alunos da 5ª. série do ensino fundamental em questões sobre injustiça na escola aplicadas em 2003. Para análise teórica, foram utilizadas as abordagens da Psicologia do Desenvolvimento Moral de Piaget e Kohlberg e da Representação Social, criada por Moscovici. Comparando as duas pesquisas, a de 1999 e a de 2003, conclui-se que em nenhuma das séries a escola aparece como uma "comunidade justa" e que prevalecem os casos de injustiça retributiva e legal. Como principais agentes de injustiças aparecem, primeiramente, o professor perante seus alunos e, em segundo lugar, os alunos entre eles mesmos. Os alunos de escola particular apontaram mais o professor como agente de injustiças que os de escola pública. Entre esses as injustiças entre alunos foi mais citada. Os alunos de escola pública se posicionaram contra regras escolares que se opõem às necessidades pessoais com mais veemência que os de escola particular.This article reports on two studies that aimed at the investigation of how students from elementary and secondary schools, both private and public, from the town of Presidente Prudente (SP represent situations of injustice at school, as well as their agents and the kind of actions they take.

Technological and scientific research in La Spezia (an Italian town with a population of 95.378) is, unfortunately, unknown to most people and often the existence of excellent research Centres (such as CNR-ISMAR, CNR-IENI, ENEA-UTMAR, INGV, CMRE, CSSN and University) is barely known, even just outside the La Spezia area. The current economic crisis has played a major role in determining the decline in maritime business (affecting all companies in the area and particularly SMEs). Therefore it is important to re-establish the relationship with the traditional maritime culture of the city. This objective can be achieved by enhancing research visibility (national and european) by dissemination of the activities carried out by research institutions, university and local enterprises. La Spezia has a long maritime tradition and it is vital for these customs to be kept alive and cultivated within the community. The cultural scene is positive: in fact, in the last decade the general public's perception on the importance of science in the context of human activities has been considerably strengthened. In La Spezia, especially since 2007, an increasing number of disseminating activities (carried out by CNR-ISMAR, CNR-IENI, ENEA-UTMAR, INGV, CMRE, CSSN, LABTER - the La Spezia association for environmental education- ASSOCIAZIONE FESTIVAL DELLA SCIENZA - the association that organizes the Genoa Science Festival- Genoa University and ISA 2 - "2 GIUGNO" - a local primary and secondary public school that has started a pilot project for marine biology), has revealed an educational and cultural path which now requires a monitoring protocol to be carried out for at least two years. In this paper we will present a new test that will be administered to the entire student population (aged 6 to 18 years) with the aim to fully understand the effectiveness of initiatives for popularizing science and the impact that they are having on new generations (professional choices, scientific

Elementary particles and cosmology
International Nuclear Information System (INIS)
Audouze, J.; Paty, M.
2000-01-01
The universe is the most efficient laboratory of particle physics and the understanding of cosmological processes implies the knowledge of how elementary particles interact. This article recalls the mutual influences between on the one hand: astrophysics and cosmology and on the other hand: nuclear physics and particle physics. The big-bang theory relies on nuclear physics to explain the successive stages of nucleo-synthesis and the study of solar neutrinos has led to discover new aspects of this particle: it is likely that neutrinos undergo oscillations from one neutrino type to another. In some universe events such as the bursting of a super-nova, particles are released with a kinetic energy that would be impossible to reach on earth with a particle accelerator. These events are become common points of interest between astrophysicists and particle physicists and have promoted a deeper cooperation between astrophysics and elementary particle physics. (A.C.)

Quark matter is a special case of condensed elementary particle matter, matter governed by the laws of particle physics. The talk discusses how far one can get in the study of particle matter by reducing the problem to computations based on the action. As an example the computation of the phase diagram of electroweak matter is presented. It is quite possible that ultimately an antireductionist attitude will prevail: experiments will reveal unpredicted phenomena not obviously reducible to the study of the action. (orig.)

Full Text Available Elementary school in Germany has changed during the last five years because, among other reasons, movement has entered it. The title's pun calls attention for two lines of work that characterize school pedagogy contemporary discussion. One of these lines is related to the last 15 years changing process at elementary school: it states that elementary school must be a learning and living place for children. The other line is related to movement pedagogy processes, which has been achieving higher and higher dimensions. Elementary school must be seen from movement point of view and must be transformed in a place for movement.

Elementary particles in curved spaces
International Nuclear Information System (INIS)
Lazanu, I.
2004-01-01
The theories in particle physics are developed currently, in Minkowski space-time starting from the Poincare group. A physical theory in flat space can be seen as the limit of a more general physical theory in a curved space. At the present time, a theory of particles in curved space does not exist, and thus the only possibility is to extend the existent theories in these spaces. A formidable obstacle to the extension of physical models is the absence of groups of motion in more general Riemann spaces. A space of constant curvature has a group of motion that, although differs from that of a flat space, has the same number of parameters and could permit some generalisations. In this contribution we try to investigate some physical implications of the presumable existence of elementary particles in curved space. In de Sitter space (dS) the invariant rest mass is a combination of the Poincare rest mass and the generalised angular momentum of a particle and it permits to establish a correlation with the vacuum energy and with the cosmological constant. The consequences are significant because in an experiment the local structure of space-time departs from the Minkowski space and becomes a dS or AdS space-time. Discrete symmetry characteristics of the dS/AdS group suggest some arguments for the possible existence of the 'mirror matter'. (author)

Highlights: → Five new elementary chaotic snap flows and a generalization of an existing chaotic snap flow have been presented. → Three of all are conservative systems whilst three others are dissipative systems. → Four cases need only a single control parameter and a single nonlinearity. → A cubic case in a jerk representation requires only two terms and a single nonlinearity. - Abstract: Hyperjerk systems with 4th-order derivative of the form x .... =f(x ... ,x .. ,x . ,x) have been referred to as snap systems. Five new elementary chaotic snap flows and a generalization of an existing flow are presented through an extensive numerical search. Four of these flows demonstrate elegant simplicity of a single control parameter based on a single nonlinearity of a quadratic, a piecewise-linear or an exponential type. Two others demonstrate elegant simplicity of all unity-in-magnitude parameters based on either a single cubic nonlinearity or three cubic nonlinearities. The chaotic snap flow with a single cubic nonlinearity requires only two terms and can be transformed to its equivalent dynamical form of only five terms which have a single nonlinearity. An advantage is that such a chaotic flow offers only five terms even though the (four) dimension is high. Three of the chaotic snap flows are characterized as conservative systems whilst three others are dissipative systems. Basic dynamical properties are described.

Hypertension is a common disease and a crucial predisposing factor of cardiovascular diseases. Approximately 10% of hypertensive patients are secondary hypertension, a pathogenetic factor of which can be identified. Secondary hypertension consists of endocrine, renal, and other diseases. Primary aldosteronism, Cushing's syndrome, pheochromocytoma, hyperthyroidism, and hypothyroidism result in endocrine hypertension. Renal parenchymal hypertension and renovascular hypertension result in renal hypertension. Other diseases such as obstructive sleep apnea syndrome are also very prevalent in secondary hypertension. It is very crucial to find and treat secondary hypertension at earlier stages since most secondary hypertension is curable or can be dramatically improved by specific treatment. One should keep in mind that screening of secondary hypertension should be done at least once in a daily clinical practice.

Some difficulties, connected with correct application of supersymmetry mathematical tools in the field and elementary particle theory are pointed out. The role of Grassman algebra in the usual field theory and the role of Lee superalgebra in supertransformations mixing bosons and fermions are shown. Grassman algebra in the theory of supersymmetries plays a role of numerical field. A supersymmetrical model, when indexes {i} of Grassman algebra corresponding to ''color'', and indexes {α} of Lee superalgebra representations - to ''flavor'', is considered. It is marked that the problem of interpretation of Grassman algebra indexes is a key one for the theory of supersymmetries. In particular, it gives no possibility to come from the theory of supersymmetries to the usual field theory, whose indexes of Grassman algebra possess obvious physical meaning

NASA's Elementary and Secondary Education Program: Review and Critique
Quinn, Helen R. (Editor); Schweingruber, Heidi A. (Editor); Feder, Michael A. (Editor)
2008-01-01
The federal role in precollege science, technology, engineering, and mathematics (STEM) education is receiving increasing attention in light of the need to support public understanding of science and to develop a strong scientific and technical workforce in a competitive global economy. Federal science agencies, such as the National Aeronautics and Space Administration (NASA), are being looked to as a resource for enhancing precollege STEM education and bringing more young people to scientific and technical careers. For NASA and other federal science agencies, concerns about workforce and public understanding of science also have an immediate local dimension. The agency faces an aerospace workforce skewed toward those close to retirement and job recruitment competition for those with science and engineering degrees. In addition, public support for the agency s missions stems in part from public understanding of the importance of the agency s contributions in science, engineering, and space exploration.

Notes on elementary particle physics
Muirhead, William Hugh
1972-01-01
Notes of Elementary Particle Physics is a seven-chapter text that conveys the ideas on the state of elementary particle physics. This book emerged from an introductory course of 30 lectures on the subject given to first-year graduate students at the University of Liverpool. The opening chapter deals with pertinent terminologies in elementary particle physics. The succeeding three chapters cover the concepts of transition amplitudes, probabilities, relativistic wave equations and fields, and the interaction amplitude. The discussion then shifts to tests of electromagnetic interactions, particul
Preservice elementary teachers learning of astronomy
Fidler, Chuck Gary
formatted for journal submission. Chapter 1 outlines the intent, rationale, and design of the overall dissertation process and format. Chapter 2 describes an in-depth review of the specific astronomy curricula used for comparison by subsequent chapters and is not intended as a standalone article, but rather as an informative outline of events and activities to help the reader understand the differences of instruction between the two sections of sample populations. Chapter 3 uses qualitative interviews to explore the cosmic dimensions associated with learning of astronomy and finds diverse perceptions of astronomical scales may influence preservice teachers' mental organization of astronomical information. Chapter 4 further analyzes cosmic dimensions using quantitative analyses and specifically examines preservice teachers perceptions of scale and spatiality within the context of astronomy education. Findings from Chapter 4 show that perceptions of scale and spatiality are an interconnected set of learning skills which may greatly enhance the learning of astronomy. Chapter 5 describes how concepts of scale and spatiality may be operationalized within a secondary school science classroom in order to better understand the scaled distances of stars though an inquiry-based three-dimensional modeling activity. Chapter 6 briefly concludes the dissertation work. Due to the nature of this dissertation design, the conclusions chapter is quite succinct as previous chapters are designed with conclusions sections embedded within the body of the text as outlined by specific journal submission guidelines. These dissertation ideas are presented in a formal setting so that the various research undertakings can be studied and analyzed. Qualitative and quantitative analyses of research data are present to support the claims made in this study. The results of this research combine with features of previous research in order to advance our understanding of how preservice elementary teachers

Dimensional considerations about elementary particles
International Nuclear Information System (INIS)
Cocconi, G.
1978-01-01
The search for fundamental elementary particles responsible for the observed behaviour of matter during the past decades is briefly reviewed, and the possibility is considered that the four fundamental interactions that shape things merge into a unique field when matter is so compressed that particles are at extremely small distances from one another. These interactions are the gravitational interaction, the electromagnetic interaction, the strong interaction, and the weak interaction. It is thought that a simple geometrical criterion, termed the 'elementary criterion', would suffice to indicate how the various interactions should behave as particles are brought closer to one another and thus approach the situation where all interactions merge.

Do Elementary Particles Have an Objective Existence?
Nissenson, Bilha
2007-01-01
The formulation of quantum theory does not comply with the notion of objective existence of elementary particles. Objective existence independent of observation implies the distinguishability of elementary particles. In other words: If elementary particles have an objective existence independent of observations, then they are distinguishable. Or if elementary particles are indistinguishable then matter cannot have existence independent of our observation. This paper presents a simple deductio...

Lord, J.J.; Burnett, T.H.; Wilkes, R.J.
1989-01-01
We are carrying out a research program in high energy experimental particle physics. Studies of high energy hadronic interactions and leptoproduction processes continue using several experimental techniques. Progress has been made on the study of multiparticle production processes in nuclei. Ultra-high energy cosmic ray nucleus-nucleus interactions have been investigated by the Japanese American Cosmic Emulsion Experiment (JACEE) using balloon-borne emulsion chamber detectors. In the area of particle astrophysics, our studies of cosmic ray nuclear interactions have enabled use to make the world's most accurate determination of the comparison of the cosmic rays above 10 13 eV. We have only the detector that can observe interaction vertices and identify particles at energies up to 10**15 eV. Our observations are getting close to placing limits on the acceleration mechanisms postulated for pulsars in which the spin and magnetic moment axes are at different angles. In June, 1989 approval was given by NASA for our participation in the Space Station program. The SCINATT experiment will make use of emulsion chamber detectors, similar to the planned JACEE hybrid balloon flight detectors. These detector will permit precise determination of secondary particle charges, momenta and rapidities, and the accumulation of data will be at least a factor of 10 to 100 greater than in balloon experiments. Emulsion chamber techniques ate also employed in an experiment using accelerator heavy ion beams at CERN and Brookhaven National Laboratory to investigate particle production processes in central collisions of nuclei in the energy range 15 -- 200A GeV. Our study of hadroproduction in lepton interactions is continuing with approval of another 8 months run for deep inelastic muon scattering experiment E665 at Fermilab

Generalized osteoporosis currently represents a heterogeneous group of conditions with many different causes and pathogenetic mechanisms, that often are variably associated. The term "secondary" is applied to all patients with osteoporosis in whom the identifiable causal factors are other than menopause and aging. In this heterogeneous group of conditions, produced by many different pathogenetic mechanisms, a negative bone balance may be variably associated with low, normal or increased bone remodeling states. A consistent group of secondary osteoporosis is related to endocrinological or iatrogenic causes. Exogenous hypercortisolism may be considered an important risk factor for secondary osteoporosis in the community, and probably glucocorticoid-induced osteoporosis is the most common type of secondary osteoporosis. Supraphysiological doses of corticosteroids cause two abnormalities in bone metabolism: a relative increase in bone resorption, and a relative reduction in bone formation. Bone loss, mostly of trabecular bone, with its resultant fractures is the most incapacitating consequence of osteoporosis. The estimated incidence of fractures in patients prescribed corticosteroid is 30% to 50%. Osteoporosis is considered one of the potentially serious side effects of heparin therapy. The occurrence of heparin-induced osteoporosis appeared to be strictly related to the length of treatment (over 4-5 months), and the dosage (15,000 U or more daily), but the pathogenesis is poorly understood. It has been suggested that heparin could cause an increase in bone resorption by increasing the number of differentiated osteoclasts, and by enhancing the activity of individual osteoclasts. Hyperthyroidism is frequently associated with loss of trabecular and cortical bone; the enhanced bone turnover that develops in thyrotoxicosis is characterized by an increase in the number of osteoclasts and resorption sites, and an increase in the ratio of resorptive to formative bone
Evidence of significant bias in an elementary random number generator

An elementary pseudo random number generator for isotropically distributed unit vectors in 3-dimensional space has ben tested for bias. This generator uses the IBM-suplied routine RANDU and a transparent rejection technique. The tests show clearly that non-randomness in the pseudo random numbers generated by the primary IBM generator leads to bias in the order of 1 percent in estimates obtained from the secondary random number generator. FORTRAN listings of 4 variants of the random number generator called by a simple test programme and output listings are included for direct reference. (orig.) [de

Osteoporosis with attendant increased fracture risk is a common complication of many other diseases. Indeed, almost all chronic diseases make some impact on life-style, usually by restricting physical activity and hence reducing the anabolic effect of exercise and gravitational strains on the skeleton. Restricted appetite and modified gastrointestinal tract function is another commonplace finding that has an impact on bone nutrition and synthesis, as on other systems. Sex hormone status is of particular importance for the maintenance of the normal skeleton, and the postmenopausal woman is at particular risk for most causes of secondary osteoporosis. In dealing with secondary osteoporosis in the hypo-oestrogenic woman, the question of giving hormone replacement therapy in addition to other disease-specific therapy should always be considered, as, for example, in a young amenorrhoeic woman with Crohn's disease. Similarly, in hypogonadal men the administration of testosterone is useful for bone conservation. The wider availability of bone densitometry ought to make us more aware of the presence of osteoporosis in the many disease states discussed above. This is particularly important as the life span of such patients is now increased by improved management of the underlying disease process in many instances. Even in steroid-induced osteoporosis--one of the commonest and most severe forms of osteoporosis--we now have some effective therapy in the form of the bisphosphonates and other anti-bone-resorbing drug classes. The possibility of prophylaxis against secondary osteoporosis has therefore become a possibility, although the very long-term effects of such drug regimens are still unknown. In some situations, such as thyrotoxicosis, Cushing's syndrome and immobilization, spontaneous resolution of at least part of the osteoporosis is possible after cure of the underlying problem. The shorter the existence of the basic problem, the more successful the restoration of the

Full Text Available ABSTRACT It is shown the inexistence of neutrinos to define precisely the concept of relativistics mass under this scheme to elementarys particles as electron and interactions particles like photons correspond an electromagnetic and virtual mass. Nucleons protons and neutrons have real or inertial mass for being composite particles since inertia needs structure it is provided by an interactive network originated by strong and weak forces. This mass is building up atoms and all the material world under Classical Physics and Chemistrys laws.These actual masses may be considered as electromagnetic and virtual one thanks to its charge in order to establish the high energies level needed to obtain all particles physics elementary or not which are governed by the laws of Quantum Physics. With all this one may set up amore reasonable and understandable new Standard Model which being projected into Cosmological Model can get rid of some inconsistencies and concepts difficult to be admitted.

Adrenal Mass Causing Secondary Hypertension.
Robinson, Darlene Y
2015-11-01
Most hypertensive patients have essential (primary) hypertension; only 5% to 10% have a secondary cause. Two clinical characteristics suggestive of secondary hypertension are early onset (hypertension (>180/110 mm Hg). When faced with these findings, clinicians should consider a secondary cause of hypertension. A 22-year-old woman being evaluated for asthma exacerbation in the emergency department was noted to have severe persistent hypertension. Additional evaluation revealed severe hypokalemia, metabolic alkalosis, and hypernatremia. The patient was admitted to the hospital for blood pressure management, electrolyte replacement, and further evaluation of presumed hyperaldosteronism. Diagnostic imaging revealed a large adrenal mass. Surgical resection was performed, leading to a diagnosis of hyperaldosteronism caused by adrenal carcinoma. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Secondary hypertension is far less common than essential hypertension; however, considering the large volume of patients seen in emergency departments, it is likely that some will have secondary hypertension. Emergency physicians should be aware of the clinical characteristics that suggest secondary hypertension so that the appropriate diagnostic and treatment pathways can be pursued.

The elementary process of Bremsstrahlung
Haug, Eberhard
2004-01-01
This book deals with the theory and experiment of the elementary process of bremsstrahlung, where photons are detected in coincidence with decelerated outgoing electrons. Such experiments allow for a more stringent check of the theoretical work. The main emphasis is laid on electron-atom bremsstrahlung and electron-electron bremsstrahlung, but further bremsstrahlung processes are also dealt with. In the theoretical parts, triply differential cross sections are derived in various approximations, including electron spin and photon-polarization. In the experimental sections, electron-photon coinc

The first International Committee for Future Accelerators Instrumentation School was held at the International Centre for Theoretical Physics, Trieste, Italy from 8 to 19 June 1987. The School was attended by 74 students of whom 45 were from developing countries, 10 lecturers and 9 laboratory instructors. The next generation of elementary particle physics experiments would depend vitally on new ideas in instrumentation. This is a field where creativity and imagination play a major role and large budgets are not a prerequisite. One of the unique features was the presentation of four laboratory experiments using modern techniques and instrumentation. Refs, figs and tabs.

String model of elementary particles
International Nuclear Information System (INIS)
Kikkawa, Keiji
1975-01-01
Recent development of the models of elementary particles is described. The principal features of elementary particle physics can be expressed by quark model, mass spectrum, the Regge behavior of scattering amplitude, and duality. Venezians showed in 1968 that the B function can express these features. From the analysis of mass spectrum, the string model was introduced. The quantization of the string is performed with the same procedure as the ordinary quantum mechanics. The motion of the string is determined by the Nambu-Goto action integral, and the Schroedinger equation is obtained. Mass spectrum from the string model was same as that from the duality model such as Veneziano model. The interaction between strings can be introduced, and the Lagrangian can be formulated. The relation between the string model and the duality model has been studied. The string model is the first theory of non-local field, and the further development is attractive. The relation between this model and the quark model is still not clear. (Kato, T.)
Explorations in Elementary Mathematical Modeling
Directory of Open Access Journals (Sweden)
Mazen Shahin
2010-06-01
Full Text Available In this paper we will present the methodology and pedagogy of Elementary Mathematical Modeling as a one-semester course in the liberal arts core. We will focus on the elementary models in finance and business. The main mathematical tools in this course are the difference equations and matrix algebra. We also integrate computer technology and cooperative learning into this inquiry-based learning course where students work in small groups on carefully designed activities and utilize available software to support problem solving and understanding of real life situations. We emphasize the use of graphical and numerical techniques, rather than theoretical techniques, to investigate and analyze the behavior of the solutions of the difference equations.As an illustration of our approach, we will show a nontraditional and efficient way of introducing models from finance and economics. We will also present an interesting model of supply and demand with a lag time, which is called the cobweb theorem in economics. We introduce a sample of a research project on a technique of removing chaotic behavior from a chaotic system.
Quantum mechanics from elementary view
International Nuclear Information System (INIS)
Fischer, Karl
2009-01-01
This book offers an introduction to quantum mechanics as well as interesting supplements up to the beginnings of quantum field theory. A comprehensive mathematical block facilitates the access. It is rich on examples and otherwise mostly not findable calculations, which make it so transparent in its results. It likes the historical relations and brings so the feeling how much has been grown from the past. It brings also a short outline about relativity theory up to the understanding of the term ''metrics''. The spotlight holds the term product space, by means of which quantum mechanics is put together to a practicable theory. A simpler notation for instance at the Dirac equation facilitates also the understanding. On the mathematical side it is above all the term distributive law as well as the term linear combination, which lead so simple transparent definitions fast to more general. Generally it is tried to find an as possible elementary access to at least not elementary connections. So may it be for many both instructive and interesting
Structures in elementary particles. An electromagnetic elementary-particle model
International Nuclear Information System (INIS)
Meyer, Carl-Friedrich
2015-01-01
A picture of matter is developed, which is suited to develope and to explain the experimentally determined properties of the elementary particles and the basing structures starting from few known physical conditions in a simple and understandable way. It explains illustratively the spin and the structure of the stable particles, symmetry properties resulting from the half-integerness of the spin, the nature of the electric charge and the third-integerness of the charges in hadrons resulting from this, the stability and the indivisibility f the proton, the conditions for the formation and stability of the particles, and the causes for the limited lifetime of unstable particles like the free neutron. It opens also the view on the cause for the quantization of all for us known processes in the range of the microcosm and creates so an illustrative picture of the matter surrounding us.

2007-01-01
Department of Training and Consulting is regularly serving secondary schools' pupils and teachers, university students and the public. As usual we have been visited by about 7000 visitors, mainly students from secondary schools in Poland. The Department is constantly developing experiments which can be conducted by students of secondary schools and universities, as well as by professionals. At the moment there are about 20 experiments available for the guests of the Department. They cover measurements of the lifetimes, elements of radioprotection, absorption of radiation in various materials, excitation of fluorescence radiation, influence of magnetic field on beta radiation as well as electrons emitted from typical electron gun, Compton scattering and elements of gamma spectroscopy, search for radioactive pollutions etc. In addition the Department was very active during Science Picnic in May and Science Festival in September, when the Department proposed organisation of a '' Day with Radioactivity ''. '' The Day '' consisted of a number of public lectures and demonstrations. In addition two evenings were dedicated to a public debate on energy sources and energy demands and supply in next 50-100 years. One should also mention organisation and leading of the professional course for accelerators' operators, as well as starting a new university course on '' Nuclear Energy and Its Use '' (Cardinal Stefan Wyszynski University, Warsaw). The web side of the Department contains educational materials (part of it can be found on international platform http://www.nupex.org), quizzes and self-teaching materials. (author)

Carreras, B.; Fernandez, E.
1973-01-01
The purpose of these notes is to given an elementary introduction to the ideas underlying the Regge-type models. In lectures 1 and 2 the connection between the exchange models and the Regge form of the amplitude is shown. In lecture 3 the analytic continuation of the amplitude from the t-channel to the s-schanel is considered, leading to the Regge-type expression, and then (lecture 4), some phenomenological applications are discussed. Lectures 5 and 6 are a generalization of 3 and 4 to the scattering of non-zero spin particles. finally (lectures 7,8 and 9) Regge cuts are introduced and new phenomenological applications are discussed.

An excursion through elementary mathematics
Caminha Muniz Neto, Antonio
2017-01-01
This book provides a comprehensive, in-depth overview of elementary mathematics as explored in Mathematical Olympiads around the world. It expands on topics usually encountered in high school and could even be used as preparation for a first-semester undergraduate course. This first volume covers Real Numbers, Functions, Real Analysis, Systems of Equations, Limits and Derivatives, and much more. As part of a collection, the book differs from other publications in this field by not being a mere selection of questions or a set of tips and tricks that applies to specific problems. It starts from the most basic theoretical principles, without being either too general or too axiomatic. Examples and problems are discussed only if they are helpful as applications of the theory. Propositions are proved in detail and subsequently applied to Olympic problems or to other problems at the Olympic level. The book also explores some of the hardest problems presented at National and International Mathematics Olympiads, as we...
Elementary introduction to conformal invariance
International Nuclear Information System (INIS)
Grandati, Y.
1992-01-01
These notes constitute an elementary introduction to the concept of conformal invariance and its applications to the study of bidimensional critical phenomena. The aim is to give an access as pedestrian as possible to this vast subject. After a brief account of the general properties of conformal transformation in D dimensions, we study more specifically the case D = 2. The center of the discussion is then the consequences of the action of this symmetry group on bidimensional field theories, and in particular the links between the representations of the Virasoro algebra and the structure of the correlation functions of conformal field theories. Finally after showing how the Ising model reduces to a Majorana fermionic field theory, we see how the general formalism previously discussed can be applied to the Ising case at the critical point.

Some Elementary Aspects of Means
Directory of Open Access Journals (Sweden)
Mowaffaq Hajja
2013-01-01
Full Text Available We raise several elementary questions pertaining to various aspects of means. These questions refer to both known and newly introduced families of means, and include questions of characterizations of certain families, relations among certain families, comparability among the members of certain families, and concordance of certain sequences of means. They also include questions about internality tests for certain mean-looking functions and about certain triangle centers viewed as means of the vertices. The questions are accessible to people with no background in means, and it is also expected that these people can seriously investigate, and contribute to the solutions of, these problems. The solutions are expected to require no more than simple tools from analysis, algebra, functional equations, and geometry.
Topics in elementary scattering theory
International Nuclear Information System (INIS)
Imrie, D.C.
1980-01-01
In these lectures a summary is given of some of the fundamental ideas and formalism used to describe and understand the interactions of elementary particles. A brief review of relativistic kinematics is followed by a discussion of Lorentz-invariant variables for describing two-body processes, phase space and plots, such as the Dalitz plot, which can be used to study some aspects of the dynamics of an interaction, relatively free from kinematic complications. A general description of scattering and decay is given and then, more specifically, some aspects of two-body interactions in the absence of spin are discussed. Finally, complications that arise when particle spin has to be taken into account are considered. (U.K.)

Tracking and imaging elementary particles
International Nuclear Information System (INIS)
Breuker, H.; Drevermann, H.; Grab, C.; Rademakers, A.A.; Stone, H.
1991-01-01
The Large Electron-Positron (LEP) Collider is one of the most powerful particle accelerators ever built. It smashes electrons into their antimatter counterparts, positrons, releasing as much as 100 billion electron volts of energy within each of four enormous detectors. Each burst of energy generates a spray of hundreds of elementary particles that are monitored by hundreds of thousands of sensors. In less than a second, an electronic system must sort through the data from some 50,000 electron-positron encounters, searching for just one or two head-on collisions that might lead to discoveries about the fundamental forces and the elementary particles of nature. When the electronic systems identify such a promising event, a picture of the data must be transmitted to the most ingenious image processor ever created. The device is the human brain. Computers cannot match the brain's capacity to recognize complicated patterns in the data collected by the LEP detectors. The work of understanding subnuclear events begins therefore through the visualization of objects that are trillions of times smaller than the eye can see and that move millions of times faster than the eye can follow. During the past decade, the authors and their colleagues at the European laboratory for particle physics (CERN) have attempted to design the perfect interface between the minds of physicists and the barrage of electronic signals from the LEP detectors. Using sophisticated computers, they translate raw data - 500,000 numbers from each event - into clear, meaningful images. With shapes, curves and colors, they represent the trajectories of particles, their type, their energy and many other properties
The geometry of elementary particles
International Nuclear Information System (INIS)
Lov, T.R.
1987-01-01
A new model of elementary particles based on the geometry of Quantum deSitter space QdS = SU (3,2)/(SU(3,1) x U(1)) is introduced and studied. QdS is a complexification of quantization of anti-de Sitter space, AdS = SO(3,2)/SO(3,1), which in recent years had played a pivotal role in supergravity. The nontrival principle fiber bundle has total space SU(3,2), fiber SU(3,1) x U(1) and base QdS. In this setting, the standard recipes for Yang-Mills fields don't work. These require connections and the associated covariant derivatives. Here it is shown that the Lie derivatives, not the covariant derivatives are important in quantization. In this setting, the no-go theorems are not valid. This new quantum mechanics leads to a model of elementary particles as vertical vector fields in the bundle with interaction via the Lie bracket. There are five physical interactions modelled by the bracket interaction. The quantum numbers are identified as the roots of su(3,2) and are preserved under the bracket interaction. The model explains conservation of charge, baryon number, lepton number, parity and the heirarchy problem. Since the bracket is the curvature of a homogeneous space, particles are then the curvature of QdS. This model for particles is consistent with the requirements of General Relativity. Furthermore, since the curvature tensor is built from the quantized wave functions, the curvature tensor is quantized and this is quantum theory of gravity
Theoretical & Experimental Studies of Elementary Particles

McFarland, Kevin [Univ. of Rochester, NY (United States)
2012-10-04
Abstract High energy physics has been one of the signature research programs at the University of Rochester for over 60 years. The group has made leading contributions to experimental discoveries at accelerators and in cosmic rays and has played major roles in developing the theoretical framework that gives us our ``standard model'' of fundamental interactions today. This award from the Department of Energy funded a major portion of that research for more than 20 years. During this time, highlights of the supported work included the discovery of the top quark at the Fermilab Tevatron, the completion of a broad program of physics measurements that verified the electroweak unified theory, the measurement of three generations of neutrino flavor oscillations, and the first observation of a ``Higgs like'' boson at the Large Hadron Collider. The work has resulted in more than 2000 publications over the period of the grant. The principal investigators supported on this grant have been recognized as leaders in the field of elementary particle physics by their peers through numerous awards and leadership positions. Most notable among them is the APS W.K.H. Panofsky Prize awarded to Arie Bodek in 2004, the J.J. Sakurai Prizes awarded to Susumu Okubo and C. Richard Hagen in 2005 and 2010, respectively, the Wigner medal awarded to Susumu Okubo in 2006, and five principal investigators (Das, Demina, McFarland, Orr, Tipton) who received Department of Energy Outstanding Junior Investigator awards during the period of this grant. The University of Rochester Department of Physics and Astronomy, which houses the research group, provides primary salary support for the faculty and has waived most tuition costs for graduate students during the period of this grant. The group also benefits significantly from technical support and infrastructure available at the University which supports the work. The research work of the group has provided educational opportunities

In this paper, we describe the possibilities of using a rapid mental computation system in elementary education. The system consists of a number of readily memorized operations that allow one to perform arithmetic computations very quickly. These operations are actually simple algorithms which can develop or improve the algorithmic thinking of pupils. Using a rapid mental computation system allows forming the basis for the study of computer science in secondary school.

Elementary process theory axiomatic introduction and applications
Cabbolet, Marcoen J T F
2011-01-01
Modern physics lacks a unitary theory that applies to all four fundamental interactions. This PhD thesis is a proposal for a single, complete, and coherent scheme of mathematically formulated elementary laws of nature. While the first chapter presents the general background, the second chapter addresses the method by which the main result has been developed. The next three chapters rigorously introduce the Elementary Process Theory, its mathematical foundations, and its applications to physics, cosmology and philosophy of mind. The final two chapters discuss the results and present the conclusions. Summarizing, the Elementary Process Theory is a scheme of seven well-formed closed expressions, written in the mathematical language of set matrix theory – a generalization of Zermelo-Fraenkel set theory. In the physical world, these seven expressions can be interpreted as elementary principles governing the universe at supersmall scale. The author critically confronts the theory with Quantum Mechanics and Genera...

On the Origin of Elementary Particle Masses
Hansson, Johan
2012-01-01
The oldest enigma in fundamental particle physics is: Where do the observed masses of elementary particles come from? Inspired by observation of the empirical particle mass spectrum we propose that the masses of elementary parti cles arise solely due to the self-interaction of the fields associated with a particle. We thus assume that the mass is proportional to the strength of the interaction of th e field with itself. A simple application of this idea to the fermi...

Are black holes elementary particles? Are they fermions or bosons? We investigate the remarkable possibility that quantum black holes are the smallest and heaviest elementary particles. We are able to construct various fundamental quantum black holes: the spin-0, spin 1/2, spin-1, and the Planck-charge cases, using the results in general relativity. Quantum black holes in the neighborhood of the Galaxy could resolve the paradox posed by the Greisen-Zatsepin-Kuzmin limit on the energy of cosmi...

A one-day summer workshop on '' Basics of nuclear radiation, its properties and use in science, technology and medicine '' offered secondary school teachers a general understanding of the problems connected with radioactivity. The Department is constantly developing experiments that can be conducted by students of secondary schools and universities, as well as by professionals. At the moment, there are about 25 experiments available for the guests of the Department. They cover the measurement of lifetimes, essential elements of radioprotection, absorption of radiation in various materials, excitation of fluorescence radiation, influence of magnetic fields on beta radiation as well as on electrons emitted from a typical electron gun, Compton scattering and elements of gamma spectroscopy, search for radioactive pollutions etc. Three experiments were modernized to enable them to be conducted over the Internet. This project is a bit delayed but should be finished by the end of April 2009. For the third time the Department organized (together with the Institute of Physics of the Polish Academy of Sciences, Warsaw) '' The Physical Pathways '' competition for secondary school students. The students could choose one of three possibilities (even all of them): either to submit a scientific paper, to present a demonstration of a physical phenomenon, or to write an essay on the connection between physics and the development of civilization. They could also submit work prepared by a team of up to three persons. The

One of the unique aspects of atomic physics is the capacity to make measurements with extraordinarily high precision. In suitably chosen systems, precision measurements can reveal information about fundamental interactions in nature that is not available from other sources. Although elementary particle physics is often perceived as synonymous with open-quotes high energyclose quotes and open-quotes high cost,close quotes atomic physics has played, and can continue to play, a significant role in this area. A few illustrative examples of this include (1) the measurement of the Lamb shift in hydrogen and its, influence on the modern development of quantum field theory, (2) the severe limits placed on possible time reversal violating interactions by atomic (and neutron) searches for electric dipole moments, and (3) the measurement (and closely related atomic theory) of parity, nonconservation in atoms. This latter work has provides a precise confirmation of the Standard Model of the weak, electromagnetic, and strong interactions, and is a uniquely sensitive test for the validity of a variety of alternative models that have been put forth. I will also discuss some of the joys and frustrations of doggedly pursuing the open-quotes ultimateclose quotes measurement of ridiculously tiny effects

Task A of this contract supports research in elementary particle physics using cryogenic particle detectors. We have developed superconducting aluminum tunnel-junction detectors sensitive to a variety of particle signals, and with potential application to a number of particle-physics problems. We have extended our range of technologies through a collaboration with Simon Labov, on niobium tri-layer junctions, and Jean-Paul Maneval, on high-T c superconducting bolometers. We have new data on response to low-energy X-rays and to alpha-particle signals from large-volume detectors. The theoretical work under this contract (Task B) is a continued investigation of nonperturbative aspects of quantum gravity. A Monte Carlo calculation is proposed for Euclidian quantum gravity, based on the ''fifth-time action'' stabilization procedure. Results from the last year include a set of seven papers, summarized below, addressing various aspects of nonperturbative quantum gravity and QCD. Among the issues- addressed is the so-called ''problem of time'' in canonical quantum gravity

Lessons to measure natural radiation have been given at the fourth elementary school of Hikari-gaoka, Nerima-ku, Tokyo, for three years. The Method of Lessons: After hearing a brief explanation about natural radiation and usage of a simple instrument of gamma ray named 'Hakaru-kun' by a lecturer (Fig. 1), every child participates to measure dose rate at several measured points within the range of school campus (Figs. 5 - 14). They calculate the average value of measured dose rate (Fig. 2) and affix tags written the average value (Fig. 3). In addition, by looking at the photographs, through the imaging plate, of radiations released from vegetables and pork, they are surprised at the fact that all the food have such activities. Finally, they watch marks of alpha particles released from the ore of samarskite in a cloud chamber. The alpha particles fly in alcohol vapor over saturated cooled with dry ice (Fig. 15). They express their impression of lesson for finding out the existence of natural radiation in their reports. (Table 1 and Fig. 4). (author)

Amino acid code of protein secondary structure.
Shestopalov, B V
2003-01-01
The calculation of protein three-dimensional structure from the amino acid sequence is a fundamental problem to be solved. This paper presents principles of the code theory of protein secondary structure, and their consequence--the amino acid code of protein secondary structure. The doublet code model of protein secondary structure, developed earlier by the author (Shestopalov, 1990), is part of this theory. The theory basis are: 1) the name secondary structure is assigned to the conformation, stabilized only by the nearest (intraresidual) and middle-range (at a distance no more than that between residues i and i + 5) interactions; 2) the secondary structure consists of regular (alpha-helical and beta-structural) and irregular (coil) segments; 3) the alpha-helices, beta-strands and coil segments are encoded, respectively, by residue pairs (i, i + 4), (i, i + 2), (i, i = 1), according to the numbers of residues per period, 3.6, 2, 1; 4) all such pairs in the amino acid sequence are codons for elementary structural elements, or structurons; 5) the codons are divided into 21 types depending on their strength, i.e. their encoding capability; 6) overlappings of structurons of one and the same structure generate the longer segments of this structure; 7) overlapping of structurons of different structures is forbidden, and therefore selection of codons is required, the codon selection is hierarchic; 8) the code theory of protein secondary structure generates six variants of the amino acid code of protein secondary structure. There are two possible kinds of model construction based on the theory: the physical one using physical properties of amino acid residues, and the statistical one using results of statistical analysis of a great body of structural data. Some evident consequences of the theory are: a) the theory can be used for calculating the secondary structure from the amino acid sequence as a partial solution of the problem of calculation of protein three

A New Approach to Teaching Science to Elementary Education Majors in Response to the NGSS
Brevik, C.; Daniels, L.; McCoy, C.
2015-12-01
The Next Generation Science Standards (NGSS) place an equal emphasis on science process skills and science content. The goal is to have K-12 students "doing" science, not just "learning about" science. However, most traditional college science classes for elementary education majors place a much stronger emphasis on science content knowledge with the hands-on portion limited to a once-a-week lab. The two models of instruction are not aligned. The result is that many elementary school teachers are unprepared to offer interactive science with their students. Without additional coaching, many teachers fall back on the format they learned in college - lecture, handouts, homework. If we want teachers to use more hands-on methods in the classroom, these techniques should be taught to elementary education majors when they are in college. Dickinson State University has begun a collaboration between the Teacher Education Department and the Department of Natural Sciences. The physical science course for elementary education majors has been completely redesigned to focus equally on the needed science content and the science process skills emphasized by the NGSS. The format of the course has been adjusted to more closely mirror a traditional K-5 classroom; the course meets for 50 minutes five days a week. A flipped-classroom model has been adopted to ensure no content is lost, and hands-on activities are done almost every day as new concepts are discussed. In order to judge the effectiveness of these changes, a survey tool was administered to determine if there was a shift in the students' perception of science as an active instead of a passive field of study. The survey also measured the students' comfort-level in offering a hands-on learning environment in their future classrooms and their confidence in their ability to effectively teach science concepts to elementary students. Results from the first year of the study will be presented.
Elementary particle physics in early physics education
Wiener, Gerfried
2017-01-01
Current physics education research is faced with the important question of how best to introduce elementary particle physics in the classroom early on. Therefore, a learning unit on the subatomic structure of matter was developed, which aims to introduce 12-year-olds to elementary particles and fundamental interactions. This unit was iteratively evaluated and developed by means of a design-based research project with grade-6 students. In addition, dedicated professional development programmes were set up to instruct high school teachers about the learning unit and enable them to investigate its didactical feasibility. Overall, the doctoral research project led to successful results and showed the topic of elementary particle physics to be a viable candidate for introducing modern physics in the classroom. Furthermore, thanks to the design-based research methodology, the respective findings have implications for both physics education and physics education research, which will be presented during the PhD defen...
Norms of certain Jordan elementary operators
Zhang, Xiaoli; Ji, Guoxing
2008-10-01
Let be a complex Hilbert space and let denote the algebra of all bounded linear operators on . For , the Jordan elementary operator UA,B is defined by UA,B(X)=AXB+BXA, . In this short note, we discuss the norm of UA,B. We show that if and ||UA,B||=||A||||B||, then either AB* or B*A is 0. We give some examples of Jordan elementary operators UA,B such that ||UA,B||=||A||||B|| but AB*[not equal to]0 and B*A[not equal to]0, which answer negatively a question posed by M. Boumazgour in [M. Boumazgour, Norm inequalities for sums of two basic elementary operators, J. Math. Anal. Appl. 342 (2008) 386-393].
Topics in elementary particle physics
Jin, Xiang
The author of this thesis discusses two topics in elementary particle physics: n-ary algebras and their applications to M-theory (Part I), and functional evolution and Renormalization Group flows (Part II). In part I, Lie algebra is extended to four different n-ary algebraic structure: generalized Lie algebra, Filippov algebra, Nambu algebra and Nambu-Poisson tensor; though there are still many other n-ary algebras. A natural property of Generalized Lie algebras — the Bremner identity, is studied, and proved with a totally different method from its original version. We extend Bremner identity to n-bracket cases, where n is an arbitrary odd integer. Filippov algebras do not focus on associativity, and are defined by the Fundamental identity. We add associativity to Filippov algebras, and give examples of how to construct Filippov algebras from su(2), bosonic oscillator, Virasoro algebra. We try to include fermionic charges into the ternary Virasoro-Witt algebra, but the attempt fails because fermionic charges keep generating new charges that make the algebra not closed. We also study the Bremner identity restriction on Nambu algebras and Nambu-Poisson tensors. So far, the only example 3-algebra being used in physics is the BLG model with 3-algebra A4, describing two M2-branes interactions. Its extension with Nambu algebra, BLG-NB model, is believed to describe infinite M2-branes condensation. Also, there is another propose for M2-brane interactions, the ABJM model, which is constructed by ordinary Lie algebra. We compare the symmetry properties between them, and discuss the possible approaches to include these three models into a grand unification theory. In Part II, we give an approximate solution for Schroeder's equations, based on series and conjugation methods. We use the logistic map as an example, and demonstrate that this approximate solution converges to known analytical solutions around the fixed point, around which the approximate solution is constructed

EELV Secondary Payload Adapter (ESPA)
Haskett, Scott A.; Weis, Steven C.; Doggrell, Leslie J.; Sciulli, Dino; Meink, Troy E.; Ganley, Jeff T.; Maly, Joseph R.; Jurisson, Karl
2000-11-01
Despite growing international interest in small satellites, high dedicated expendable launch vehicle costs and the lack of secondary launch opportunities continue to hinder the full exploitation of small satellite technology. In the United States, the Department of Defense (DoD), NASA, other government agencies, commercial companies, and many universities use small satellites to perform space experiments, demonstrate new technology, and test operational prototype hardware. In addition, the DoD continues to study the role of small satellites in fulfilling operational mission requirements. However, the US lacks sufficient small satellite launch capacity. Furthermore, US government agencies are restricted to the use of US launch vehicles, which eliminates many affordable launch opportunities. In an effort to increase the number of space experiments that can be flown with a small, fixed budget, the DoD Space Test Program (STP) has teamed with the Air Force Research Laboratory Space Vehicles Directorate (AFRL/VS) to develop a low-cost solution for the small satellite launch program. Our solution, which can be implemented on both Boeing and Lockheed-Martin Evolved Expendable Launch Vehicle-Medium (EELV-M) boosters, is called the EELV Secondary Payload Adaptor (ESPA). ESPA will increase the number of launch opportunities for 180kg-class (or smaller) satellites at prices highly competitive with other secondary launch services worldwide.

Research activity of the Department of the Theoretical Physics spans a wide variety of problems in theoretical high-energy and elementary particle physics, theoretical nuclear physics, theory of the nuclear matter, quark gluon plasma and relativistic heavy-ion collisions, theoretical astrophysics, as well as general physics. Theoretical research in high energy and elementary particle physics is concentrated on the theory of deep inelastic lepton scattering in the region of low x and its phenomenological implication for the ep collider HERA at DESY, on the theory of nonleptonic decays of hadrons, and on low energy {pi}{pi} and K-anti-K interactions and scalar meson spectroscopy. The activity in the theory of relativistic heavy-ion collisions is focused on the study of quark condensate fluctuations, on the analysis of critical scattering near the chiral phase transition, and on Bose-Einstein correlation in heavy-ion collisions. Theoretical studies in nuclear physics and in theory of nuclear matter concern analysis of models, with dynamical symmetry based on group S{sub p}(6,R) for the description of collective modes of atomic nuclei, analysis of the Goldstone bosons in nuclear matter and analysis of saturation properties of nuclear matter. Research in theoretical astrophysics is mainly devoted to the analysis of magnetic properties of hadronic matter in neutron stars with proton admixture. Studies in general physics concern problem related to the Galilean covariance of classical and quantum mechanics. The detailed results obtained in various fields are summarised in presented abstracts as well as information about employed personnel, publications, contribution to conferences, reports, workshops and seminars.

Full Text Available Jung Un Jang,1 Inn-Jee Park2 1Department of Optometry, Eulji University, Seongnam, 2Department of Optometry, Kaya University, Gimhae, South Korea Purpose: To assess the prevalence of refractive errors among elementary school children in South Jeolla Province of South Korea. Methods: The subjects were aged 8–13 years; a total of 1,079 elementary school children from Mokpo, South Jeolla Province, were included. In all participants, uncorrected visual acuity and objective and subjective refractions were determined using auto Ref-Keratometer and phoropter. A spherical equivalent of -0.50 diopter (D or worse was defined as myopia, +0.50 D or more was defined as hyperopia, and a cylinder refraction greater than 0.75 D was defined as astigmatism. Results: Out of 1,079 elementary school children, the prevalence of uncorrected, best-corrected, and corrected visual acuity with own spectacles of 20/40 or worse in the better eye was 26.1%, 0.4%, and 20.2%, respectively. The uncorrected visual acuity was 20/200 or worse in the better eye in 5.7% of school children, and 5.2% of them already wore corrective spectacles. The prevalence of myopia, hyperopia, and astigmatism was 46.5% (95% confidence interval [CI]: 43.56–49.5, 6.2% (95% CI: 4.92–7.81, and 9.4% (95% CI: 7.76–11.25, respectively. Conclusion: The present study reveals a considerably higher prevalence of refractive error among elementary school children in South Jeolla Province of South Korea, exceeding 50% of subjects. The prevalence of myopia in the school children in Korea is similar to many other countries including People’s Republic of China, Malaysia, and Hong Kong. This may indicate that genetics and educational influences, such as studying and learning, may play a role in the progression of myopia in Korean elementary school children. Keywords: refractive error, elementary school children, visual acuity, myopia, astigmatism
Secondary fuel delivery system
Parker, David M.; Cai, Weidong; Garan, Daniel W.; Harris, Arthur J.
2010-02-23
A secondary fuel delivery system for delivering a secondary stream of fuel and/or diluent to a secondary combustion zone located in the transition piece of a combustion engine, downstream of the engine primary combustion region is disclosed. The system includes a manifold formed integral to, and surrounding a portion of, the transition piece, a manifold inlet port, and a collection of injection nozzles. A flowsleeve augments fuel/diluent flow velocity and improves the system cooling effectiveness. Passive cooling elements, including effusion cooling holes located within the transition boundary and thermal-stress-dissipating gaps that resist thermal stress accumulation, provide supplemental heat dissipation in key areas. The system delivers a secondary fuel/diluent mixture to a secondary combustion zone located along the length of the transition piece, while reducing the impact of elevated vibration levels found within the transition piece and avoiding the heat dissipation difficulties often associated with traditional vibration reduction methods.
Secondary and tertiary hyperparathyroidism.
Jamal, Sophie A; Miller, Paul D
2013-01-01
We reviewed the etiology and management of secondary and tertiary hyperparathyroidism. Secondary hyperparathyroidism is characterized by an increase in parathyroid hormone (PTH) that is appropriate and in response to a stimulus, most commonly low serum calcium. In secondary hyperparathyroidism, the serum calcium is normal and the PTH level is elevated. Tertiary hyperparathyroidism is characterized by excessive secretion of PTH after longstanding secondary hyperparathyroidism, in which hypercalcemia has ensued. Tertiary hyperparathyroidism typically occurs in men and women with chronic kidney disease usually after kidney transplant. The etiology and treatment of secondary hyperparathyroidism is relatively straightforward whereas data on the management of tertiary hyperparathyroidism is limited to a few small trials with short follow-up.

Bubbles, shocks and elementary technical trading strategies
Fry, John
2014-01-01
In this paper we provide a unifying framework for a set of seemingly disparate models for bubbles, shocks and elementary technical trading strategies in financial markets. Markets operate by balancing intrinsic levels of risk and return. This seemingly simple observation is commonly over-looked by academics and practitioners alike. Our model shares its origins in statistical physics with others. However, under our approach, changes in market regime can be explicitly shown to represent a phase transition from random to deterministic behaviour in prices. This structure leads to an improved physical and econometric model. We develop models for bubbles, shocks and elementary technical trading strategies. The list of empirical applications is both interesting and topical and includes real-estate bubbles and the on-going Eurozone crisis. We close by comparing the results of our model with purely qualitative findings from the finance literature.
Elementary school teachers’ knowledge on dyslexia
Directory of Open Access Journals (Sweden)
Isabelly Silva do Nascimento
Full Text Available ABSTRACT Objective: to describe the knowledge of elementary school teachers on child dyslexia. Methods: 10 teachers from the 1st to the 5th year of elementary education in public schools in the municipality of Abreu e Lima, Pernambuco, Brazil, participated in the study. A semi-structured interview was conducted with each teacher, individually, in the school itself and was based on some guiding questions. Results: content analysis allowed the identification of three thematic categories: 1. Teacher training does not address dyslexia; 2. Feelings and difficulties of the literacy teacher facing the challenges of literacy; 3. Lack of knowledge about dyslexia: school management of possibly dyslexic children. Conclusion: the research revealed the lack of knowledge of literacy teachers on dyslexia, despite having undergraduate and postgraduate education, as well as that of teachers who participated in training offered by the municipal education network.

Studies of phenomena within high-current plasma concentrators, 3. Development of plasma diagnostic methods, 4. Studies in the field of fusion technology, 5. Research on new plasma-ion technologies. Theoretical studies mainly concerned elementary processes occurring within a plasma, and particularly those within near-electrode regions of microwave discharges as well as those within near-wall layers (SOL) of tokamaks. We also developed computational packages for parameter identification and modelling of physical phenomena in pulse plasma coaxial accelerators. Experimental studies were concentrated on the generation of a dense magnetized plasma in different high-current PF (Plasma Focus) facilities and small Z-Pinch devices. We carried out investigations of X-rays, relativistic electron beams (REBs), accelerated primary ions, and fast products of fusion reactions for deuterium discharges. Research on plasma diagnostics comprised the development of methods and equipment for studies of X-ray emission, pulsed electron beams, and fast ions, using special Cherenkov-type detectors of electrons and solid-state nuclear track detectors (SSNTDs) of ions. New diagnostic techniques were developed. Studies in the field of fusion technology concerned the design, construction, and testing of different high-voltage pulse generators. We also developed special opto-electronic systems for control and data transmission. Research on plasma-ion technology concentrated on the generation of pulsed high-power plasma-ion streams and their applications for the surface modification of semiconductors, pure metals and alloys. The material engineering studies were carried out in close collaboration with our P-9 Department and other domestic and foreign research centers

Physical Origin of Elementary Particle Masses
Hansson, Johan
2014-01-01
In contemporary particle physics, the masses of fundamental particles are incalculable constants, being supplied by experimental values. Inspired by observation of the empirical particle mass spectrum, and their corresponding physical interaction couplings, we propose that the masses of elementary particles arise solely due to the self-interaction of the fields associated with the charges of a particle. A first application of this idea is seen to yield correct order of magnitude predictions f...

Preservice Elementary Teachers' Ideas About Scientific Practices
Ricketts, Amy
2014-10-01
With the goal of producing scientifically literate citizens who are able to make informed decisions and reason critically when science intersects with their everyday lives, the National Research Council (NRC) has produced two recent documents that call for a new approach to K-12 science education that is based on scientific practices, crosscutting concepts, and disciplinary core ideas. These documents will potentially influence future state standards and K-12 curricula. Teachers will need support in order to teach science using a practices based approach, particularly if they do not have strong science backgrounds, which is often the case with elementary teachers. This study investigates one cohort (n = 19) of preservice elementary teachers' ideas about scientific practices, as developed in a one-semester elementary science teaching methods course. The course focused on eight particular scientific practices, as defined by the National Research Council's A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012). Participants' written reflections, lesson plans and annotated teaching videos were analyzed in fine detail to better understand their ideas about what it means to engage in each of the practices. The findings suggest that preservice elementary teachers hold promising ideas about scientific practices (such as an emphasis on argumentation and communication between scientists, critical thinking, and answering and asking questions as the goal of science) as well as problematic ideas (including confusion over the purpose of modeling and the process of analysis, and conflating argumentation and explanation building). These results highlight the strengths and limitations of using the Framework (NRC 2012) as an instructional text and the difficulties of differentiating between preservice teachers' content knowledge about doing the practices and their pedagogical knowledge about teaching the practices.

Good, I.J.

The paper concerns the numerology on the masses of elementary particles, and examines the formula m(n)-m(p)/m(p) 136α/6x120 (where m(n) and m(p) are the rest masses of the neutron and proton respectively and α is the fine structure constant). The author reports that this simple relationship between fundamental constants is correct to one part in at least 51,000, and is comfortably consistent with experimental results. (U.K.)

Written narrative practices in elementary school students.
Romano-Soares, Soraia; Soares, Aparecido José Couto; Cárnio, Maria Silvia
2010-01-01
Promotion of a written narratives production program in the third grade of an Elementary School. To analyze two written narrative practice proposals in order to verify which resources are more efficient in benefitting the textual productions of third grade Elementary School students. Sixty students were selected from two third grade groups of a public Elementary School in São Paulo (Brazil). For the analysis, students were divided into two groups (Group A and Group B). Fourteen children's storybooks were used. In Group A, the story was orally told by the researchers in a colloquial manner, keeping the narrator role and the original structure proposed by the author. In Group B, the story was fully read. The book was projected onto a screen and read aloud so the students could follow the reading and observe the corresponding illustrations. Voice changing resources in the characters' dialogues were used. In the overall comparison, statistically significant results were found for moment (initial and final assessments) and for interaction between groups. It was observed that both groups presented substantial development from initial to final assessment. The Written Narratives Promotion Program based on the shared reading of children's storybooks constituted a more effective strategy than telling the stories using a single reader.
Implementing Elementary School Next Generation Science Standards
Kennedy, Katheryn B.
Implementation of the Next Generation Science Standards requires developing elementary teacher content and pedagogical content knowledge of science and engineering concepts. Teacher preparation for this undertaking appears inadequate with little known about how in-service Mid-Atlantic urban elementary science teachers approach this task. The purpose of this basic qualitative interview study was to explore the research questions related to perceived learning needs of 8 elementary science teachers and 5 of their administrators serving as instructional leaders. Strategies needed for professional growth to support learning and barriers that hamper it at both building and district levels were included. These questions were considered through the lens of Schon's reflective learning and Weick's sensemaking theories. Analysis with provisional and open coding strategies identified informal and formal supports and barriers to teachers' learning. Results indicated that informal supports, primarily internet usage, emerged as most valuable to the teachers' learning. Formal structures, including professional learning communities and grade level meetings, arose as both supportive and restrictive at the building and district levels. Existing formal supports emerged as the least useful because of the dominance of other priorities competing for time and resources. Addressing weaknesses within formal supports through more effective planning in professional development can promote positive change. Improvement to professional development approaches using the internet and increased hands on activities can be integrated into formal supports. Explicit attention to these strategies can strengthen teacher effectiveness bringing positive social change.

It is often argued that the negative development of intrinsic motivation in elementary school strongly depends on the presence of school grades because grades represent extrinsic consequences and achievement feedback that are supposed to influence intrinsically motivated behaviour. However, only a few studies have tested this hypothesis. Therefore, we investigated the role of school grades in inter- and intra-individual changes in elementary school students' intrinsic motivation from when grades were first introduced until the end of elementary school, when students in Germany receive recommendations for a secondary school type on the basis of their prior performance in school. A sample of 542 German elementary school students (t 1 : M = 7.95 years, SD = 0.57) was followed for 2 years from the end of Grade 2 to the end of Grade 4. At seven measurement occasions, children's math grades and their domain-specific intrinsic motivation were assessed. Latent growth curve models showed differences in trajectories of intrinsic motivation across students rather than uniform development. Moreover, students' trajectories of grades and intrinsic motivation were only weakly associated. A latent cross-lagged model revealed that reciprocal effects between the two constructs over time were small at best. Contrary to theoretical considerations, our results indicate that negative performance feedback in the form of grades does not necessarily lead to a decrease in intrinsic motivation. This calls into question the common opinion that a perception of being less competent, as reflected by poor grades, is responsible for weakening students' intrinsic motivation. © 2017 The British Psychological Society.

Full text: The Department of Training and Consulting is regularly serving secondary school pupils and teachers, university students and the public. As usual we have been visited by more than 5000 visitors, mainly students from secondary schools. Since January 2003, the Department participated in an European program called NUPEX (from Nuclear Physics Experience) that aimed at creating an internet platform of educational material from nuclear physics and its applications. The platform was finally prepared in eight languages (English, French, German, Italian, Flemish, Greek, Hungarian and Polish) and is dedicated to pupils from secondary schools and to science teachers. The whole material can be found at http://www.nupex.org. The Polish part is displayed additionally at http://ipj.gov.pl/pl/szkolenia/nupex. It is worth mentioning that the Polish group played an important role in the whole project. Seven modules were fully prepared by us; we also were active in helping the other Project's participants to understand technicalities connected with preparation of the material for internet. New educational posters have been designed by the Department. The titles of these posters are: Energy and its transformations; typical electric power plants; Nuclear Power Plants; Nuclear Power Plants in Europe and in the World. The posters are offered to visiting schools. The number of possible experiments at our Laboratory of Atomic Physics is still increasing. Recently a computer simulation of the process of start-up of the nuclear reactor was prepared. Although it can be considered as a game, in fact the animation reflects the reality of the process and can be used for training of nuclear reactor's operators. For the first time one, of the leading secondary schools in Warsaw, the Stefan Batory School, participated in a Summer School of Physics organized at our Department, which lasted 10 days. Most of the educational program was filled with the basics of nuclear physics with emphasis

The software tool is developed for detailed and evident displaying of information about energy and space distribution of secondary particles produced in the processes of elementary particles collisions. As input information the data on the components of 4-momenta of secondary particles is used. As for these data the information obtained from different parts of physical detector (for example, from the calorimeter or tracker) as well as the information obtained with the help of event generator is taken. The tool is intended for use in Windows operation system and is developed on the basis of Borland Delphi. Mathematical architecture of the software tool allows user to receive complete information without making additional calculations. The program automatically performs analysis of structure and distributions of signals and displays the results in a transparent form which allows their quick analysis. To display the information the three-dimensional graphic methods as well as colour decisions based on intuitive associations are also used. (author)

The simple examples of spontaneous breaking of various symmetries for the scalar theory with fundamental mass have been considered. Higgs' generalizations on 'fundamental masses' that was introduced into the theory on a basis of the five-dimensional de Sitter space. The connection among 'fundamental mass', 'Planck's mass' and 'maxim ons' has been found. Consequently, the relationship among G-gravitational constant and other universal parameters can be established. The concept the mass having its root from deep antiquity (including Galilee's Pis sans experiment, theoretical research of the connection of mass with the Einstein's energy etc.) still remains fundamental. Every theoretical and experimental research in classical physics and quantum physics associated with mass is of step to the discernment of Nature. Besides of mass, the other fundamental constants such as Planck's constant ℎ and the speed of light also play the most important role in the modern theories. The first one related to quantum mechanics and the second one is related to the theory of relativity. Nowadays the properties and interactions of elementary particles can be described more or less adequately in terms of local fields that are affiliated with the lowest representations of corresponding compact groups of symmetry. It is known that the mass of any body is composed of masses of its comprising elementary particles. The mass of elementary particles is the Casimir operator of the non-compact Poincare group, and those representations of the given group, that are being used in Quantum Field Theory (QFT), and it can take any values in the interval of 0≤m≤∞. Two particles, today referred to as elementary particles, can have masses; distinct one from another by many orders. For example, vectorial bosons with the mass of ∼10 15 GeV take place in general relativity theory modules, whereas the mass of an electron is only ∼0.5·10 3 GeV. Formally, the standard QFT remains logical in a case

An increasing number of studies show that teachers have one of the most stressful occupations. Long-term work stress may lead to burnout, which gravely affects teachers' physical and mental health, lowers the quality of their work, and, in turn, impairs their students' physical and mental health and development and imperils the sound development…

In search of elementary spin 0 particles
International Nuclear Information System (INIS)
Krasny, Mieczyslaw Witold; Płaczek, Wiesław
2015-01-01
The Standard Model of strong and electroweak interactions uses point-like spin 1/2 particles as the building bricks of matter and point-like spin 1 particles as the force carriers. One of the most important questions to be answered by the present and future particle physics experiments is whether the elementary spin 0 particles exist, and if they do, what are their interactions with the spin 1/2 and spin 1 particles. Spin 0 particles have been searched extensively over the last decades. Several initial claims of their discoveries were finally disproved in the final experimental scrutiny process. The recent observation of the excess of events at the LHC in the final states involving a pair of vector bosons, or photons, is commonly interpreted as the discovery of the first elementary scalar particle, the Higgs boson. In this paper we recall examples of claims and subsequent disillusions in precedent searches spin 0 particles. We address the question if the LHC Higgs discovery can already be taken for granted, or, as it turned out important in the past, whether it requires a further experimental scrutiny before the existence of the first ever found elementary scalar particle is proven beyond any doubt. An example of the Double Drell–Yan process for which such a scrutiny is indispensable is discussed in some detail. - Highlights: • We present a short history of searches of spin 0 particles. • We construct a model of the Double Drell–Yan Process (DDYP) at the LHC. • We investigate the contribution of the DDYP to the Higgs searches background

Are quarks and leptons composite or elementary
International Nuclear Information System (INIS)
Peccei, R.D.
1986-01-01
In these lectures I discuss the issue of the origin of the quark and lepton masses, both in the case in which these objects are elementary and in the case they are composite. Some of the generic predictions and dynamical assumptions of GUTS, family symmetry models and superstrings are detailed. They are contrasted to the dynamics required for composite models of quarks and leptons. In this latter case, the difficulties of protecting dynamically fermion masses and yet still generating intra and interfamily hierarchies is emphasized. (orig.)
Elementary particles and emergent phase space
Zenczykowski, Piotr
2014-01-01
The Standard Model of elementary particles, although very successful, contains various elements that are put in by hand. Understanding their origin requires going beyond the model and searching for ""new physics"". The present book elaborates on one particular proposal concerning such physics. While the original conception is 50 years old, it has not lost its appeal over time. Its basic idea is that space - an arena of events treated in the Standard Model as a classical background - is a concept which emerges from a strictly discrete quantum layer in the limit of large quantum numbers. This bo

New developments in elementary-particle physics
Zichichi, A
1979-01-01
The modern attempt at unification of all the forces in nature is based on supersymmetry. To achieve the unification of strong and electroweak forces the distinction between leptons and hadrons (quarks) must go. The fundamental symmetry of nature is the SU(3)/sub c/ gauge symmetry, where c stands for colour. There are three colours which are the basic changes of nature and act between quarks and gluons. Elementary particles are now thought to be made of quarks and gluons. The fundamental forces of nature now appear to be the superstrong (which generates strong and semi-strong forces), electroweak (generating electromagnetic, weak and superweak) and gravitational forces.

Job satisfaction of Jamaican elementary school teachers
Rodgers-Jenkinson, Fay; Chapman, David W.
1990-09-01
This study investigated correlates of job satisfaction among public (N=190) and private (N=100) Jamaican elementary school teachers. Emphasis was on the identification of factors that could be affected through administrative intervention. Results indicated that the quality of school working conditions and respondents' relationships with other teachers were significantly related to satisfaction for both public and private school teachers. School prestige and parental encouragement were also significant predictors for public school teachers; leadership style, organizational structure, and teacher-parent relationships predicted job satisfaction for private school teachers. Implications of these findings for Jamaican education are discussed.
On combinatorial properties of elementary intramolecular operations

Full Text Available Here we tackle a problem from biology in terms of discrete mathematics. We are interested in a complex DNA manipulation process happening in eukaryotic organisms of a subclass of ciliate species called {\\it Stichotrichia} during so-called gene assembly. This process is in particular interesting since one can interpret gene assembly in ciliates as sorting of permutations. We survey here results related to studies on sorting permutations with some specific rewriting rules that formalize elementary intramolecular gene assembly operations. The research question is ``what permutation may be sorted with our operations?"
Elementary Particles The first hundred years

To mark the centenary of the discovery of that first elementary particle, the electron, some remarks and recollections from the early days of high energy physics, including the impact of early experiments and ideas on todayÕs research. Much of our progress in this field has been carefully anticipated and planned, but a surprising number of successes were the result of incredibly lucky breaks, where headway was made despite - or even because of - incorrect experimental results, crossed wires or simply asking the wrong question at the right time. We can be sure therefore that the next century - or perhaps even what remains of this one - will have unexpected surprises in store.

The basic elementary particles as martensitic nucleus
International Nuclear Information System (INIS)
Aguinaco-Bravo, V. J.; Onoro, J.
1999-01-01
The martensitic transformation is a diffusional structural change that produces an important modification of the microstructure and properties of materials. In this paper we propose how the martensitic phase is nucleated from a basic elementary particle (bep). The bep is formed in several stages. Vacancies, divacancies, etc. are formed at high temperature, which collapse into prismatic dislocation loops during the cooling process. We define a bep as a dislocation loop reaching a critical radius and fulfilling certain elastic energy conditions. A martensitic nucleus is a bep that coincides crystallographically with the habit plane of the matrix. (Author) 16 refs
A psychotherapeutic approach with elementary school teachers.
Multari, G
1975-01-01
The tradional "lectures delivering" approach to classroom teachers used by mental health practitioners is investigated in the present study. An attempt is made to demonstrate the validity of preventative work in helping elementary school teachers as important agents in the promotion of more positive mental hygiene in the classroom and by adding to the lectures the variable of group therapy--"ego-sparing" techniques type. The latter approach seems to promote a teacher's own sense of security in dealing the pupils, an easier acceptance of differences in others, and, finally, it tends to stimulate the development of a teacher's own ability to deal sensibly, more conscientiously, and more realistically with daily problems.

In 1995, the Virginia Department of Education approved a federal mandate for No Child Left Behind 2001 Education Act implementing the Standards of Learning (SOL) in four content areas: Mathematics, Science, English, and History and Social Sciences. These new guidelines set forth learning and achievement expectations for content areas for grades K-12 in Virginia's Public Schools. Given the SOL mandates, Virginia's elementary teachers and school leaders utilized research for specific teaching methods intended to encourage score improvements on end of year mathematics tests. In 2001, the concept of the Math Sprint Competition was introduced to Camelot Elementary School in Chesapeake Virginia, by researchers at Elizabeth City State University of Elizabeth City, North Carolina. Camelot Elementary, a K-5 school, is a Title I school nestled in a lower middle class neighborhood and houses a high number of minority students. On average, these students achieve lower test score gains than students in higher socioeconomic status district schools. Defined as a test-review based in relay format that utilizes released SOL test items, Math Sprint promotes mathematical skills outlined in Virginia SOL's and encourages competition among students that motivated them to quickly pick up on new material and retain the old material in order to out-do the others. Research identified was based on specific relationships between student competition and statewide testing results in mathematics for grades three, four, and five at Camelot Elementary. Data was compiled from results of the Math Sprint Competition and research focused on methods for motivating students encouraged by the use of a math sprint competition. Individual Pearson Product Moment Correlations were conducted to determine which variables possess strong and statistically significant relationships. Significantly, positive results came from 2005 to 2010 math sprints data from which students participated.

The National Research Council's most recent report Taking Science to School: Learning and Teaching Science in Grades K-8, (2007) has suggested a redefinition of science proficiency. "This framework rests on a view of science as both a body of knowledge and an evidence-based, model building enterprise that continually extends, refines, and revises knowledge" (p.2). Therefore embedding argumentation discourse within inquiry teaching includes educating students to voice their own evidence based explanations and justifications for acceptance, refinement, or possible rejection by their peers. This new perspective will require elementary teachers to challenge their own knowledge, beliefs, and practices about science proficiency. It will necessitate the creation of professional development opportunities that are specific to the needs of the teachers who are facilitating the reform during a time period when the NCLB (2001) legislation requires 100% proficiency for all students in reading and math. This intrinsic case study involved the purposive sampling of 30 regular elementary education teachers in one rural school district in Pennsylvania. A grounded theory perspective was used to examine the elementary teachers' beliefs, practices, and barriers as a means to specify the necessary supports needed to accept the challenges associated with the redefinition of science proficiency. Data was collected through a survey, observational inventory, checklist, and interviews. Using constant comparison analysis, this researcher and the district's Science Department Head, identified and refined emerging trends into the following four essential themes: equity and accountability, teacher's beliefs, isolation, and curriculum rigor. Each theme influenced instructional practices. Most notably the implementation of the teacher evaluation plan encouraged teachers to view science as a lower priority and hindered their desire to improve it. Isolation kept teachers' science knowledge and
Effects of emergency department expansion on emergency department patient flow.

2014-05-01
Emergency department (ED) crowding is an increasing problem associated with adverse patient outcomes. ED expansion is one method advocated to reduce ED crowding. The objective of this analysis was to determine the effect of ED expansion on measures of ED crowding. This was a retrospective study using administrative data from two 11-month periods before and after the expansion of an ED from 33 to 53 adult beds in an academic medical center. ED volume, staffing, and hospital admission and occupancy data were obtained either from the electronic health record (EHR) or from administrative records. The primary outcome was the rate of patients who left without being treated (LWBT), and the secondary outcome was total ED boarding time for admitted patients. A multivariable robust linear regression model was used to determine whether ED expansion was associated with the outcome measures. The mean (±SD) daily adult volume was 128 (±14) patients before expansion and 145 (±17) patients after. The percentage of patients who LWBT was unchanged: 9.0% before expansion versus 8.3% after expansion (difference = 0.6%, 95% confidence interval [CI] = -0.16% to 1.4%). Total ED boarding time increased from 160 to 180 hours/day (difference = 20 hours, 95% CI = 8 to 32 hours). After daily ED volume, low-acuity area volume, daily wait time, daily boarding hours, and nurse staffing were adjusted for, the percentage of patients who LWBT was not independently associated with ED expansion (p = 0.053). After ED admissions, ED intensive care unit (ICU) admissions, elective surgical admissions, hospital occupancy rate, ICU occupancy rate, and number of operational ICU beds were adjusted for, the increase in ED boarding hours was independently associated with the ED expansion (p = 0.005). An increase in ED bed capacity was associated with no significant change in the percentage of patients who LWBT, but had an unintended consequence of an increase in ED boarding hours. ED expansion alone does

ELEFUNT, Testing of Elementary Function Subroutines
International Nuclear Information System (INIS)
Cody, W.J.
1981-01-01
1 - Description of problem or function: ELEFUNT is a FORTRAN test package for the elementary functions. Each program is an aggressive test of one or more of the elementary function subroutines generally supplied with the support library accompanying a FORTRAN compiler. Functions tested are ALOG/ALOG10, ASIN/ACOS, ATAN, EXP, POWER, SIN/ COS, SINH/COSH, SQRT, TAN/COTAN, and TANH. 2 - Method of solution: The programs check the accuracy of the functions by using purified random arguments from appropriate intervals in carefully selected identities. They also check special properties of each function, test for the handling of special arguments, and exercise the error returns. 3 - Restrictions on the complexity of the problem: The package contains one subroutine (MACHAR) for dynamic determination of parameters describing the floating-point arithmetic system of the host machine, the test programs must be modified to insert the necessary machine- dependent parameters in DATA statements, or otherwise make them available. This computing environment inquiry routine is known to malfunction when the arithmetic registers are wider than the storage registers
Dialogical argumentation in elementary science classrooms
Kim, Mijung; Roth, Wolff-Michael
2018-02-01
To understand students' argumentation abilities, there have been practices that focus on counting and analyzing argumentation schemes such as claim, evidence, warrant, backing, and rebuttal. This analytic approach does not address the dynamics of epistemic criteria of children's reasoning and decision-making in dialogical situations. The common approach also does not address the practice of argumentation in lower elementary grades (K-3) because these children do not master the structure of argumentation and, therefore, are considered not ready for processing argumentative discourse. There is thus little research focusing on lower elementary school students' argumentation in school science. This study, drawing on the societal-historical approach by L. S. Vygotsky, explored children's argumentation as social relations by investigating the genesis of evidence-related practices (especially burden of proof) in second- and third-grade children. The findings show (a) students' capacity for connecting claim and evidence/responding to the burden of proof and critical move varies and (b) that teachers play a significant role to emphasize the importance of evidence but experience difficulties removing children's favored ideas during the turn taking of argumentative dialogue. The findings on the nature of dialogical reasoning and teacher's role provide further insights about discussions on pedagogical approaches to children's reasoning and argumentation.
Iteration in Early-Elementary Engineering Design
McFarland Kendall, Amber Leigh
K-12 standards and curricula are beginning to include engineering design as a key practice within Science Technology Engineering and Mathematics (STEM) education. However, there is little research on how the youngest students engage in engineering design within the elementary classroom. This dissertation focuses on iteration as an essential aspect of engineering design, and because research at the college and professional level suggests iteration improves the designer's understanding of problems and the quality of design solutions. My research presents qualitative case studies of students in kindergarten and third-grade as they engage in classroom engineering design challenges which integrate with traditional curricula standards in mathematics, science, and literature. I discuss my results through the lens of activity theory, emphasizing practices, goals, and mediating resources. Through three chapters, I provide insight into how early-elementary students iterate upon their designs by characterizing the ways in which lesson design impacts testing and revision, by analyzing the plan-driven and experimentation-driven approaches that student groups use when solving engineering design challenges, and by investigating how students attend to constraints within the challenge. I connect these findings to teacher practices and curriculum design in order to suggest methods of promoting iteration within open-ended, classroom-based engineering design challenges. This dissertation contributes to the field of engineering education by providing evidence of productive engineering practices in young students and support for the value of engineering design challenges in developing students' participation and agency in these practices.

Full Text Available The problem of modernization of non-special departments students’ foreign language training at Ukrainian high schools has been actualized. The author has defined the basic reasons for the failing of foreign language training as follows: restricted number of foreign language classes at non-special departments; violation of the principle of continuity of foreign language training in the hierarchy “secondary school – high school”; lack of motivation. It has been proved that among the primary tasks that need solving are the following: increasing of the course scope; revision of the organization, structure and content of the foreign language training, improving students’ motivation. The necessity to perform foreign language teaching within two training courses has been substantiated: for the students studying for their Bachelor’s Degree this is the standard (during I–III academic years and advanced (during III–IV academic years as an elective component of the curriculum, as well as for the students studying for the Master’s Degree. The necessity to seek foreign experience in level-based teaching of foreign languages and differentiate the standard course of a foreign language into the elementary and basic levels; to introduce the course “Foreign Language for Beginners” as an additional educational service for alignment, adjustment and development of foreign language knowledge and skills of students at high schools has been justified. The possibility to tackle the problem of students’ motivation improving is linked to a comprehensive approach that provides for the most effective education, development and implementation of a special system of training tasks; formation of social behaviour of collaboration and communication; improvement and modernization of teaching methods; implementation of existing pedagogical innovations (independent learning and metalearning, massive open social learning, „blended” learning, „Bring your

Full text: The Department's continuing interest is centered on the mechanisms of mutagenesis and DNA repair. Part of the studies concerns the effects of the interdependence of mutator and antimutator genes on the response of E. coli cells to various mutagens. The phenomenon of mutation frequency decline (MFD) was studied and recently distinct response of this system to UV light and to alkylating agents was shown. Studies on the isfA gene, which is involved in the regulation of the SOS response, including its precise localization on the bacterial chromosome, were continued. Also, studies on the mechanism of DNA replication-independent mutagenesis in lambda phage were continued. Halogen light mutagenesis and the role of the hem gene in the near UV and UVA irradiation mutagenesis were investigated. New experimental approaches were adapted to study adaptive mutations. Another part of the studies was focused on the relation between the structure of DNA bases adducts and their coding and mutagenic properties, as well as their properties as substrates for DNA repair enzymes. These studies include instrumental methods, such as NMR, MS, HPLC and GC/MS, to investigate structure and the kinetics of formation and excision of adducts, and organic chemistry methods to synthesize adducts. The coding and mutagenic properties of several oxidized and alkylated bases (including imidazole-ring opened purines) were determined by employing in vitro enzymatic and phage/bacteria systems. The sites of reaction of chloroacetaldehyde, a metabolite of carcinogenic vinyl chloride, with a fragment of human p53 gene, were studied using the method of polymerase fingerprint analysis. Ethenoadducts, the products of the reaction of chloroacetaldehyde with adenine and cytosine, and also products of solvolytic degradation of ethenoadenine, were studied as substrates of various DNA glycosylases. Several purine and pyrimidine derivatives were synthesized and tested as inhibitors of DNA glycosylases
Secondary traumatic stress in nurses: a systematic review.
Beck, Cheryl Tatano
2011-02-01
Is there a "cost of caring" for health care providers of traumatized patients? The aim of this study is to review the literature on secondary traumatic stress in nurses in order to answer the following questions: What studies have been conducted on secondary traumatic stress in nurses in all clinical specialties? What instruments were used to measure secondary traumatic stress in nurses and what psychometric properties were reported? A systematic review. CINAHL, PubMed, and PsycINFO databases were searched for the years 1981 to the present. Keywords used in the database searches included secondary traumatic stress, compassion fatigue, vicarious traumatization, secondary trauma, PTSD, and nurses. Research studies were reviewed for the following inclusion criteria: the sample included nurses, the secondary traumatic stress symptoms were measured, and the language was English. Seven studies were found in which researchers examined secondary traumatic stress in nurses. The samples in five of these studies consisted of all nurses, whereas in the remaining two studies, nurses were included in the samples but the results were not specifically reported for the subgroup of nurses. Presence of secondary traumatic stress was reported in forensic nurses, emergency department nurses, oncology nurses, pediatric nurses, and hospice nurses. Three instruments were identified that measured secondary traumatic stress in practitioners who care for traumatized populations: Secondary Traumatic Stress Scale, Compassion Fatigue Self Test for Helpers, and the Compassion Fatigue Scale-Revised. Presence of secondary traumatic stress in nurses was reported in all of the studies included in this literature review. The use of small samples and a number of different instruments to measure secondary traumatic stress symptoms, however, hindered the ability to make comparisons across studies and to draw conclusions. None of the studies conducted to date have focused on secondary traumatic stress in
