    Full Text Available Significance of the findings and scientific generalizations, which were made by the the leading Russian scientist of Korean Studies Natalia Bazhanova, goes far beyond the Korean issues. It is of great interest for both the expert community, and for a wide range of readers. Analysis of the political and economic development of the DPRK allowed Bazhanova highlight the characteristics of authoritarian regimes and non-market economy, and to see how they affect the foreign policy and international relations. Natalia Evgen'evna has made a great contribution to the development of historical science. She was the first who introduced into scientific use unique documents on the history of the Korean War of 1950-1953, allowing to understand the causes, course and consequences of the conflict. Bajanova proved itself as a political scientist, analyzing and forecasting the development of the international situation on the Korean Peninsula, making constructive proposals aimed at resolving the North Korean nuclear problem. The works of Bazhanova dedicated to Russian-Korean relations are very significant. Her conclusions on the current development of relations between our two countries are especially valuable, as well as on international multilateral cooperation in the matter of a Korean settlement. Natalia Evgen'evna was the author of monograph, publicistic books and papers devoted to the many countries of the world, including the United States, France, Italy, China. She put her exceptional talent to the study of these topics. The works of Bazhanova characterized by internal logic, depth and light, have “transparent” style of presentation.

  4. Representatividade lesbiana na obra Amora, De Natalia Borges Polesso

    Directory of Open Access Journals (Sweden)

    Ana Valéria Goulart dos Santos

    2018-02-01

    Full Text Available Há uma grande carência de obras literárias e escritores LGBTTQI (Lésbicas, Gays, Bissexuais, Travestis, Transexuais, Queer, Intersexuais, tirando algumas exceções de escritores gays e livros com personagens gays, é muito difícil encontrar no mercado livros com essa temática e, ainda mais raro, escritores assumidamente LGBT que conseguem escrever e publicar suas obras. Assim, a proposta deste artigo é trazer à tona uma discussão sobre a homossexualidade feminina retratada de uma forma livre de estereótipos, como na obra Amora, da autora gaúcha Natalia Borges Polesso. Além disso, também se propõe uma reflexão sobre as relações sociais e afetivas dessas protagonistas mulheres. Vale salientar que a autora é lesbiana e a temática de todos os contos também são. A minibiografia da escritora na obra não aponta esse dado pessoal de extrema relevância para a representatividade de uma parcela da população leitora, a informação, portanto, foi obtida por meio de pesquisas. Partindo da ideia de que a produção literária é um ato também político, um livro com temática homoafetiva feminina escrito por uma mulher lesbiana é imprescindível para a sociedade e, ainda assim, muito difícil de se encontrar, ainda que hajam escritoras e escritores produzindo (mesmo não sendo um número significante e um público buscando essas obras, pra se enxergar representados na literatura.

  5. Autoridades invisibles y autorizaciones visibles en la película argentina Rompecabezas de Natalia Smirnoff

    Mullaly, Laurence H.

    2013-06-01

    Full Text Available In the Argentinian cinema of the end of the 90’s and beginning of the 21st century, the representations of femininity and masculinity have become richer thanks to alternative visions, most frequently proposed by female directors. Natalia Smirnoff’s film Rompecabezas (Puzzle is a perfect example. It tells the story of an ordinary woman whose psychosexual awakening shakes up the invisible forces that had dictated her life up to that point. Rompecabezas explores the everlasting effect and influence on the patriarchal structures in constructing identity. The aim of this work, rooted in a gender perspective, is to study in what way both hierarchy and symbolic systems operate and to what extent Natalia Smirnoff provides us with a powerful (revision of transformation for women.En el cine argentino de finales de los años 90 y principios del siglo actual, las representaciones de la feminidad y la masculinidad se están enriqueciendo gracias a las visiones alternativas que nos ofrecen en su mayoría directoras. La película de Natalia Smirnoff, que se centra en la trayectoria de una mujer ordinaria cuyo despertar psicosexual choca con las autoridades invisibles que hasta ahora regían su vida, da testimonio de ello. Rompecabezas (Puzzle explora la permanencia y la influencia de las estructuras patriarcales en la construcción de las identidades. A partir de una perspectiva de género, el presente trabajo pretende analizar de qué manera opera el conjunto de las jerarquías y de los sistemas simbólicos y en qué medida Natalia Smirnoff nos proporciona una (revisión transformadora de las mujeres.

  7. Aphandra natalia(Arecaceae – a little known source of piassaba fibers from the western Amazon

    Directory of Open Access Journals (Sweden)

    Mette Kronborg

    2014-03-01

    Full Text Available Aphandra natalia(Balslev & Henderson Barfod is a multipurpose palm that is exploited both commercially and for subsistence purposes. Its fibers are important in Peruvian and Ecuadorean broom industries and support many people economically. In Brazil, it is found in the western part of Acre, where it is the main source for a local broom market. Data from fieldwork in Peru (2007 suggests that the variation in gross profit per kilogram of fiber is considerable among the different segments in the broom industry. Harvesters and distributors earn negligible amounts of money whereas manufacturers reap of the major part of the earnings. Fiber extraction appears to be sustainable in Ecuador and in some parts of Peru, whereas in other parts of Peru unsustainable harvest occurs, involving felling of entire palm trees for the harvest of fibers. The same destructive extraction method is used in Brazil, where the palm is becoming rare in its natural distribution area.

  8. GRANDIOSE SELF. ON ANOTHER PSYCHOANALYTIC ASPECT OF THE NOVEL TITO DORČIĆ WRITTEN BY VJENCESLAV NOVAK

    Directory of Open Access Journals (Sweden)

    Dejan Durić

    2011-01-01

    Full Text Available The issue of desire of the Other and jouissance Other, that were designed in the paper Desire of the Other and jouissance Other. A psychoanalitic aspect of the novel Tito Dorčić written by Vjenceslav Novak, is a complex issue of narcissism and narcissistic self, which will be discussed in this paper in the context of Kohut's self psychology and his settings on the grandiose self and idealized parental figure. The formation of the self begins through the subject's pre-Oedipal and Oedipal relations with the people he/she was in the most direct interaction, which means the father and the mother, and in our case, especially his father because the mother is reduced to a passive and muted feminine principle. Therefore, the relationship of family Dorčić against their class and other classes as well as their position in the social movement and dynamism have a direct impact on the principles of education; and a problem of narcissism is closely associated with the family and social interaction.

    Directory of Open Access Journals (Sweden)

    Juan Carlos Lara Olmo

    2018-02-01

    Full Text Available The work De translatione sanctorum martyrum Georgii monachi, Aurelii et Nathaliae ex urbe Corduba Parisios, written by Aimonius of Saint Germaindes-Prés about the year 871, was lacking a comprehensive commentary. The facts that it narrates, the events to which refers and the characters whom mentions, are so important for the history of Spain and France in the High Middle Ages, that go beyond the limits of the hagiographical frame of the story and give it a great documentary value. The author of this article examines them all within their socio-religious context, and offers the translation into Spanish of the first book of the three that constitute the work, which is the most interesting and the best to combine history and hagiography.

  6. Kinetic extensions of magnetohydrodynamic models for axisymmetric toroidal plasmas

    International Nuclear Information System (INIS)

    Cheng, C.Z.

    1989-04-01

    A nonvariational kinetic-MHD stability code (NOVA-K) has been developed to integrate a set of non-Hermitian integro-differential eigenmode equations due to energetic particles for axisymmetric toroidal plasmas in a general flux coordinate system with an arbitrary Jacobian. The NOVA-K code employs the Galerkin method involving Fourier expansions in the generalized poloidal angle θ and generalized toroidal angle /zeta/ directions, and cubic-B spline finite elements in the radial /Psi/ direction. Extensive comparisons with the existing variational ideal MHD codes show that the ideal MHD version of the NOVA-K code converges faster and gives more accurate results. The NOVA-K code is employed to study the effects of energetic particles on MHD-type modes: the stabilization of ideal MHD internal kink modes and the excitation of ''fishbone'' internal kink modes; and the alpha particle destabilization of toroidicity-induced Alfven eigenmodes (TAE) via transit resonances. Analytical theories are also presented to help explain the NOVA-K results. For energetic trapped particles generated by neutral beam injection (NBI) or ion cyclotron resonant heating (ICRH), a stability window for the n = 1 internal kink mode in the hot particle beta space exists even in the absence of the core ion finite Larmor radius effect. On the other hand, the trapped alpha particles are found to have negligible effects on the stability of the n = 1 internal kink mode, but the circulating alpha particles can strongly destabilize TAE modes via inverse Landau damping associated with the spatial gradient of the alpha particle pressure. 60 refs., 24 figs., 1 tab

His pedagogical activity has known, from the very start, brilliant achievements. Having received European studies, those over 30 students in his studio, whom Auguste Baillayre remembers in 1961, did not return to Bessarabia. Olesi Hršanovschi-Beassley (Olga Olby, Lydia Luzanovsky, Gregoire Michonze, Antoine Irisse and Joseph Bronstein studied in Paris, Felix Roitman, Helen Barlo and Natalia Bragalia – in Brussels, Elisabeth Ivanovsky, Nina Jascinsky and Nicolae Coleadici in Amsterdam. Theodor Kiriacoff worked in Romania, in Iasi and then in Bucharest, where Helen Barlo and Natalia Bragalia return after studying in France, Gheorghe Ceglocoff comes from Dresden and Galina Ceaşcenco creates her works in Prague. These are all remarkable plastic artists who affirmed themselves outside the Bessarabian borders. Their studies at the art academies „La Grand Chaumière”, „École Nationale Supérieure des Arts Décoratifs”, „Académie Julian”, „Académie Ranson” in Paris, „Académie Royale de Beaux-Arts” in Brussels, and „Académie de Beaux-Arts” in Dresden have demonstrated the professional level of Auguste Baillayre’s disciples.

    Full Text Available The aim of the study is to reveal the effectiveness of «Novoks» manufacturing by Organosin companies in preconception treatment of urinary tract infections in women with lupus nephritis and pyelonephritis gestational history. Material and methods. The study involved 30 women with gestational pyelonephritis history and 15 women with lupus nephritis. Inclusion criteria were the presence of at least one of the clinical symptoms (pain in the lumbar region, dysuria, pain in the PST region in conjunction with microbiological criteria: number of leukocytes in the urine over a field of view of 10–15; the number of colony forming units of a microorganism > 104; sensitivity to levofloxacin as a result of urine culture. Inclusion criteria: urinalysis, urine culture with antibiotic susceptibility, clinical and biochemical blood tests, an ultrasound examination of the kidneys. All women received the drug Novaks (Organosin 500 mg once daily for 5–7 days, and the probiotic Probiz Femina 1 capsule 2 times per day till 14 days. Results. After a treatment with Novaks in combination with a probiotic Probiz-Femina (Organosin noted a progressive decrease in the degree of bacteriuria, which was manifested during a urine test research absence of bacteria and decrease the number of white blood cells. Also regressed inflammatory changes in the peripheral blood. During the control urine culture after 10 days of treatment and 1 month later, revealed no growth of pathogenic organisms in the relevant titer. Conclusions. Novoks (levofloxacin is recommended for use in preconception prevention and treatment of infectious diseases of the urinary system in women at high risk. Using microbial interference therapy using modern probiotic Probiz Femina leads to a significant improvement in intestinal microbiocenosis in antibiotic therapy, reduce contamination of the intestines and the vagina, which allows you to take drug treatment Novaks without impairing the quality of life.

  12. Computer model for ductile fracture

    International Nuclear Information System (INIS)

    Moran, B.; Reaugh, J. E.

    1979-01-01

    A computer model is described for predicting ductile fracture initiation and propagation. The computer fracture model is calibrated by simple and notched round-bar tension tests and a precracked compact tension test. The model is used to predict fracture initiation and propagation in a Charpy specimen and compare the results with experiments. The calibrated model provides a correlation between Charpy V-notch (CVN) fracture energy and any measure of fracture toughness, such as J/sub Ic/. A second simpler empirical correlation was obtained using the energy to initiate fracture in the Charpy specimen rather than total energy CVN, and compared the results with the empirical correlation of Rolfe and Novak

    Ghantous, Katy; Gorelenkov, Nikolai; Berk, Herbert

    2011-10-01

    We present a self-consistent quasi-linear model that describes wave-particle interaction in toroidal geometry and computes fast ion transport during TAE mode evolution. The model bridges the gap between single mode resonances, where it predicts the analytically expected saturation levels, and the case of multiple modes overlapping, where particles diffuse across phase space. Results are presented in the large aspect ratio limit where analytic expressions are used for Fourier harmonics of the power exchange between waves and particles, . Implemention of a more realistic mode structure calculated by NOVAK code are also presented. This work is funded by DOE contract DE-AC02-09CH11466.

    The Chinese Fusion Engineering Test Reactor (CFETR) is under design. It aims to fill the gaps between ITER and DEMO. In the reactor, the deuterium-tritium fusion reaction and the auxiliary heating will generate a lot of energetic particles. It is possible that these energetic particles will drive toroidal Alfvén eigenmode (TAE) instabilities under the conditions of CFETR plasma parameters. These instabilities can result in energetic particles redistribution or loss, so it’s vital to study TAE instabilities in CFETR. The aim of this paper is to study the possibility of reducing TAE instabilities by changing safety factor profiles in CFETR. NOVA and NOVA-K codes are used to study TAE stability. The equilibria are constructed using the CORSICA code. Safety factor profiles are selected as the three typical profiles of ITER scenarios. For the three different safety factor profiles, we use NOVA to scan and calculate their continuum spectrum and eigenmode structures, then use NOVA-K to calculate the different damping and driving mechanisms for different toroidal mode numbers. The numerical calculations show that if the safety factor profiles are chosen appropriately, then all the TAEs can be stable. Thus, it’s possible to reduce the TAE instabilities by changing safety factor profiles in CFETR. We also scan the temperature and density profiles to see their effects on the TAE instabilities. It shows that the TAE instabilities keep unchanged for a wide range of profiles.

    Full Text Available »Ljubezen skozi želodec« is the first Slovenian lifestyle cooking show hosted by spouses, publishers and foodies Valentina Smej Novak and Luka Novak. The aim of the article is to determine what gender, class and national representations are reproduced by the show. The analysis of four seasons of the cooking show demonstrates that, in regard to social class and gender, »Ljubezen skozi želodec« can be compared to similar shows abroad, such as those hosted by Jamie Oliver and Nigella. Masculinity and femininity are constructed through traditional roles where the ideology of family and care for the children is vital. All this corresponds to the Slovenian socio-cultural environment characterized by Catholicism. Class identities are the reflection of Bourdieu’s taste of luxury and a contemporary omnivorous taste of an environmentally conscious consumer. As for the national angle, the Central-European and partially also the French and Italian identity are stressed rather than the Slovenian one, which puts Slovenia on the socio-cultural map of the Central Europe and at the same time negates the culinary influence of the former Yugoslav republics.

    1988-12-01

    A nonvariational ideal MHD stability code (NOVA) has been developed. In a general flux coordinate (/psi/, θ, /zeta/) system with an arbitrary Jacobian, the NOVA code employs Fourier expansions in the generalized poloidal angle θ and generalized toroidal angle /zeta/ directions, and cubic-B spline finite elements in the radial /psi/ direction. Extensive comparisons with these variational ideal MHD codes show that the NOVA code converges faster and gives more accurate results. An extended version of NOVA is developed to integrate non-Hermitian eigenmode equations due to energetic particles. The set of non-Hermitian integro-differential eigenmode equations is numerically solved by the NOVA-K code. We have studied the problems of the stabilization of ideal MHD internal kink modes by hot particle pressure and the excitation of ''fishbone'' internal kink modes by resonating with the energetic particle magnetic drift frequency. Comparisons with analytical solutions show that the values of the critical β/sub h/ from the analytical theory can be an order of magnitude different from those computed by the NOVA-K code. 24 refs., 11 figs., 1 tab

    Cheng, C.Z.

    1990-01-01

    The effects of energetic particles on MHD type modes are studied by analytical theories and the nonvariational kinetic-MHD stability code (NOVA-K). In particular we address the problems of (1) the stabilization of ideal MHD internal kink modes and the excitation of resonant ''fishbone'' internal modes and (2) the alpha particle destabilization of toroidicity-induced Alfven eigenmodes (TAE) via transit resonances. Analytical theories are presented to help explain the NOVA-K results. For energetic trapped particles generated by neutral-beam injection (NBI) or ion cyclotron resonant heating (ICRH), a stability window for the n=1 internal kink mode in the hot particle beat space exists even in the absence of core ion finite Larmor radius effect (finite ω *i ). On the other hand, the trapped alpha particles are found to resonantly excite instability of the n=1 internal mode and can lower the critical beta threshold. The circulating alpha particles can strongly destabilize TAE modes via inverse Landau damping associated with the spatial gradient of the alpha particle pressure. 23 refs., 5 figs

    Full Text Available The foundations of the Meaningful Learning Theory (MLT were laid by David Ausubel. The MLT was highly valued by the contributions of Joseph Novak and D. B. Gowin. Unlike other learning theories, the MLT has an operational component, since there are some instruments based on it and with the meaningful learning facilitation as aim. These tools were designated graphic organizers by John Trowbridge and James Wandersee (2000, pp. 100-129. One of them is the concept map created by Novak to extract meanings from an amalgam of information, having currently many applications. The other one is the Vee diagram or knowledge Vee, also called epistemological Vee or heuristic Vee. It was created by Gowin, and is an excellent organizer, for example to unpack and make transparent the unclear information from an information source. Both instruments help us in processing and becoming conceptually transparent the information, to facilitate the cognitive process of new meanings construction. In this work, after a brief introduction, it will be developed the epistemological and psychological grounds of MLT, followed by a reference to constructivist learning environments facilitators of the meaningful learning, the characterization of concept maps and exemplification of its use in various applications that have proved to be very effective from the standpoint of meaningful learning.

  3. Prediction of fracture toughness K/sub Ic/ of steel from Charpy impact test results

    This paper presents a method to predict the fracture toughness K/sub Ic/ and/or K/sub Id/ of steels using their Charpy impact test results and tensile properties. The fracture toughness, Charpy impact and tensile properties of 2 1/4 Cr-1Mo, ASTM A508 Cl.1, A508 Cl.2 A508 Cl.3 and A533 Gr.B Cl.1 steels were measured and analysed on the basis of the excess temperature (test temperature minus FATT) and Rolfe-Novak correlation. The relationship between K/sub Ic//K/sub Ic-us/ and the excess temperature, where K/sub Ic-us/ is the upper-shelf fracture toughness K/sub Ic/ predicted by Rolfe-Novak correlation, discloses that the K/sub Ic/ transition curves of several steels are representable by only one trend curve of K/sub Ic//K/sub Ic-us/ or K/sub Id//K/sub Id-us/ versus excess temperature relation. This curve is denoted as a ''master curve''. By using this curve, the fracture toughness of steel can be predicted using Charpy impact and tensile test results. By taking account of the scattering of both the fracture toughness and Charpy impact test results, the confidence limits of the master curve were also determined. Another approach to develop more general procedure of predicting the fracture toughness K/sub Ic/ is also discussed.

Experimental models are providing increasing evidence for the pharmacological management of endocannabinoid signaling not only to block the direct reinforcing effects of cannabis, opioids, nicotine and ethanol, but also for preventing relapse to the various drugs of abuse, including opioids, cocaine, nicotine, alcohol and metamphetamine. Preclinical and clinical studies suggest that the endocannabinoid system can be manipulated by the CB1 receptor antagonist SR141716A, that might constitute a new generation of compounds for treating addiction across different classes of abused drugs.Keywords: Endocannabinoids, drug dependence, opioids, nicotine, alcohol, psychostimulants

    Tell Chuera is an Early Bronze Age settlement mount in NE-Syria close to the Turkish border. With a diameter of almost 1 km and a height of 18 m it is one of the biggest tells in the region between the rivers Balikh and Khabur. In 1958 the structures of the city wall was known first by Orthmann (1990). This city wall was built of air-dried mud bricks. The age of the founding of this construction is not yet clear. The earliest pottery from the place is dated around 2500 BC to 2350 BC. Inside the fortification a road was detected, which was first excavated by Novak (1995). We took sediment monoliths in 2004 from a new trench, which shows the same situation of the road. A geomagnetic prospection, that included the whole site, suggests that the road was part of the planned extension of the lower town and serves as a circular road (Meyer, in prep.). The micromorphological investigation focussed on the question, how the road was used. Did animals have had access to the town? The thin sections show different indications of the anthropogenic influence. In all samples pseudomorphs after straw are visible. In many parts ash, charred wood fragments, bone fragments, melted material and fragments of basalt and flint were observable, too. These materials are typical for sediments in streets (cf. Goldberg & Macphail, 2006). In some parts of the thin sections faecal spherulites and dung remains with faecal spherulites give an idea that ruminants used the road as well as men. Trampling structures support this assumption. Moreover, leaching of calcite, its redeposition in mottles, pseudomycels and concretions, hydromorphic stains and the translocation of silt indicate postdepositional pedogenic processes.

    Let us start with a story of the conservatory in Prague where a Czech student Jan Snitil met a Japanese girl Masako Nakajima. Their marriage helped to initiate a cultural exchange between their countries of birth. Later Jan Snitil as the conductor of the Opera house in Opava with the help of a NPO group under his wife had a considerable success in introducing the Czech opera Dalibor (from Bedrich Smetana; stage director Josef Novak) in Japan and by realizing the first performance of the Japanese opera "Juzuru" (stage director T. Ohska) in Opava. This brought together both respective stage directors. The intensifying interest of T. Ohska for the operas of Smetana inspired J. Novak to arrange in Prague his meeting with Vaclav Nemec well known for his promotion work of the great Czech composer. In his professional career Vaclav Nemec is the internationally known Earth scientist specialized since early 1960's in the field of mathematical geology (later also in tectonics) and since 1991 respected as the "Father of Geoethics". At the meeting Nemec recognized Ohska as a Physics Professor specialized in nuclear physic and attracted him for an active participation in the field of geoethics. Prof. Ohska prepared valuable presentations for the international session on geoethics at Pribram (2011) and especially for the International Geological Congress in Brisbane (2012). At Pribram in the course of a social party Lidmila Nemcova (co-convenor of the meeting) introduced Prof. Ohska to Waclaw Demecki, Chancellor of the Higher School of Management in Legnica (Poland). Demecki has been inviting Ohska for special lectures on science as well as on cultural heritage of Japan. Professor Ohska arranges his visits to Poland through Prague where he can meet with Novak and Nemec to discuss the staging of the last opera of Smetana "Devil's Wall". Nemec in his research had finally deciphered (2012, i.e. 130 years after the first performance) the "mystery" of this opera: the composer put

    A second Neutral Beam (NB) injection line is being installed on the NSTX Upgrade device, resulting in six NB sources with different tangency radii that will be available for heating and current drive. This work explores the properties of instabilities in the frequency range of the Toroidal Alfvén Eigenmode (TAE) for NSTX-U scenarios with various NB injection geometries, from more perpendicular to more tangential, and with increased toroidal magnetic field with respect to previous NSTX scenarios. Predictions are based on analysis through the ideal MHD code NOVA-K. For the scenarios considered in this work, modifications of the Alfvén continuum result in a frequency up-shift and a broadening of the radial mode structure. The latter effect may have consequences for fast ion transport and loss. Preliminary stability considerations indicate that TAEs are potentially unstable with ion Landau damping representing the dominant damping mechanism.

    Full Text Available Concept mapping is an inquiry technique that provides students at all ages with opportunities to demonstrate learning through performance. A concept map refers to a graphic/visual representation of concepts with linking connections that show various relationships between concepts (Novak & Gowin, 1984. Assessment is an ongoing process integrated with instruction across subject areas. The National Council of Teachers of Mathematics (NCTM emphasizes that assessment should focus on both the enhancement of student learning as well as serve as a valuable tool for making instructional decisions (NCTM, 2000. Assessment activities can take on a variety of forms, one being performance tasks. In this manuscript, an explanation of concept mapping is provided for learners ages 3 – 12 along with several examples of concept maps for young learners, including examples from an assessment project in the subject area of mathematics. Also presented are the numerous benefits of the concept mapping technique for both students and teachers.

  15. A simplified analysis of dynamic interaction between soil and embedded structure

    Shimomura, Y.; Ikeda, Y.

    1993-01-01

    The simplified method of obtaining interaction stiffnesses associated with the embedded part of structures has been proposed in our previous paper. In this method, the stiffnesses are considered for three directional components, that is, lateral axis, shear and rotation, which relate to the side surface of an embedded structure. Novak et al. have derived the laterally axial and rotational stiffnesses based on the plane strain approximation for a horizontal soil layer. For practical purpose, we have given the approximate expression of the soil stiffnesses. The paper aims to capture the applicability of the approximate expression of the frequency dependent stiffnesses. The validity of approximate expression of the soil stiffnesses is discussed by their frequency dependency and the dynamic earth pressures, and the application to a multi-layered soil. The results from this proposed method are compared with the more exact results from the original 3-dimensional thin layer approach. (author)

    Full Text Available For the last 60 years, the mite-harvestman Cyphophthalmus duricorius Joseph, 1868, a soil-dwelling sironid, has been considered to be the only representative of the opilionid suborder Cyphophthalmi in Austria. However, novel data from recent collections confirm the presence of at least two further Austrian cyphophthalmid species. (1 Siro cf. crassus Novak & Giribet, 2006 occurs in at least one location in SW Styria near the Slovenian border and hence represents a member of a second genus of Austrian sironids. (2 A further morphologically distinct sironid (“Sironidae gen. et sp. nov.?” – so far undescribed and systematically not placed in detail – was collected in the borderland between Styria and Carinthia. All three species can be found in a small area of a few square-kilometers; although no syntopic occurrence was recorded.

    Full Text Available Practically all research studies concerning the teaching of Physics point out the fact that conventional instructional models fail to achieve their objectives. Many attempts have been done to change this situation, frequently with disappointing results. This work, which is the experimental stage in a research project of a greater scope, represents an effort to change to a model based on a cognitive learning theory, known as the Ausubel-Novak-Gowin theory, making use of the metacognitive tools that emerge from this theory. The results of this work indicate that the students react positively to the goals of meaningful learning, showing substantial understanding of Newtonian Mechanics. An important reduction in the study time required to pass the course has also been reported.

  20. Coupling the nongravitational forces and modified Newton dynamics for cometary orbits

    In recent work [L. Blanchet and J. Novak, Mon. Not. R. Astron. Soc. 412, 2530 (2011); L. Blanchet and J. Novak, Testing MOND in the Solar System (2011); and M. Milgrom, Mon. Not. R. Astron. Soc. 399, 474 (2009)], the authors showed that modified Newton dynamics (MOND) has a non-negligible secular perturbation effect on planets with large semimajor axes (gaseous planets) in the Solar System. Some comets also have a very eccentric orbit with a large semimajor axis (Halley family comets) going far away from the Sun (more than 15 AU) in a low acceleration regime where they would be subject to MOND perturbation. They also approach the Sun very closely (less than 3 AU) and are affected by the sublimation of ices from their nucleus, triggering so-called nongravitational forces. The main goal of this paper is to investigate the effect of MOND perturbation on three comets with various orbital elements (2 P /Encke , 1 P /Halley and 153 P /Ikeya-Zhang ) and then compare it to the nongravitational perturbations. It is motivated by the fact that when fitting an outgassing model for a comet, we have to take into account all of the small perturbing effects to avoid absorbing these effects into the nongravitational parameters. Otherwise, we could derive a completely wrong estimation of the outgassing. For this work, we use six different forms of MOND functions and compute the secular variations of the orbital elements due to MOND and nongravitational perturbations. We show that, for comets with large semimajor axis, the MONDian effects are not negligible compared to the nongravitational perturbations.

    We report here the work done for the FY14 OFES Theory Performance Target as given below: "Understanding alpha particle confinement in ITER, the world's first burning plasma experiment, is a key priority for the fusion program. In FY 2014, determine linear instability trends and thresholds of energetic particle-driven shear Alfven eigenmodes in ITER for a range of parameters and profiles using a set of complementary simulation models (gyrokinetic, hybrid, and gyrofluid). Carry out initial nonlinear simulations to assess the effects of the unstable modes on energetic particle transport". In the past year (FY14), a systematic study of the alpha-driven Alfven modes in ITER has been carried out jointly by researchers from six institutions involving seven codes including the transport simulation code TRANSP (R. Budny and F. Poli, PPPL), three gyrokinetic codes: GEM (Y. Chen, Univ. of Colorado), GTC (J. McClenaghan, Z. Lin, UCI), and GYRO (E. Bass, R. Waltz, UCSD/GA), the hybrid code M3D-K (G.Y. Fu, PPPL), the gyro-fluid code TAEFL (D. Spong, ORNL), and the linear kinetic stability code NOVA-K (N. Gorelenkov, PPPL). A range of ITER parameters and profiles are specified by TRANSP simulation of a hybrid scenario case and a steady-state scenario case. Based on the specified ITER equilibria linear stability calculations are done to determine the stability boundary of alpha-driven high-n TAEs using the five initial value codes (GEM, GTC, GYRO, M3D-K, and TAEFL) and the kinetic stability code (NOVA-K). Both the effects of alpha particles and beam ions have been considered. Finally, the effects of the unstable modes on energetic particle transport have been explored using GEM and M3D-K.

However, there is only limited information in the published literature on how to develop a tailored approach to botulinum toxin treatment.Methods: An expert panel of physicians was convened to establish a consensus on developing an individualized approach to treatment of the forehead with incobotulinumtoxinA. Separate treatment protocols were developed for men and women and subdivided by background level of muscle activity: kinetic, hyperkinetic, and hypertonic. Each muscle tone category was then further subdivided to take account of individual characteristics that can influence treatment.Results: Consensus members describe how to perform a dynamic assessment to optimize the dose and injection technique for each patient. A tailored treatment protocol is described for men and women with a wide range of forehead presentations. For each presentation, units of toxin as well as the precise location of injection points were defined by creating a 12-zone map of the forehead.Conclusion: These recommendations depart from traditional consensus documents by providing detailed incobotulinumtoxinA injection protocols for the forehead based on the major parameters that differ between patients, including muscular anatomy, size, and

    Full Text Available The main goal of the article is to outline significant contribution to the history of Belgrade ballet of those Russian dancers who came to the Kingdom of Serbia after leaving Russia in 1917, and to monitor the contribution of the next generations of Russian masters who came to Belgrade, the capital of the Kingdom of Yugoslavia, later the Socialistic Federative Republic of Yugoslavia. They have invested a lot of their effort, talent, and time, laid the foundations and provided very fast development of Belgrade ballet so that it caught up step with European ballet scene. The article, based on numerous sources and literature, including unpublished memoirs, confirmed that dancers who came after Bolshevik revolution contributed to the establishment of the national ballet center at the Belgrade National Theater and the ballet school where the first dancers of the Serbian origin were formed under the tutelage of Elena Poljakova, Nina Kirsanova, Xenia Grundt-Dumet. Celebrated ballerinas Anna Pavlova and Tamara Karsavina performed at the Belgrade stage in the twenties of the last century. In addition, unlike previously common approaches to this subject limited to the role and activity of the Russian emigration in the interwar period, the article is extended from the period during and after the Second World War to the present days. Accordingly, the paper includes the renowned Soviet masters such as Leonid Lavrovsky, Maya Plisetskaya, Natalia Dudinskaya, and those who have played important role in the contemporary ballet life in Serbia, to name Hmela, Pilipenko, Kasatkin, Logunov, and Kostjukov.

Here, we investigated chum salmon eggs (CSEs as a source of active ingredients, including vitamins, unsaturated fatty acids, and proteins. We incubated human dermal fibroblast cultures for 48 hours with high and low concentrations of CSE extracts and analyzed changes in gene expression. Cells treated with CSE extract showed concentration-dependent upregulation of collagen type I genes and of multiple antioxidative genes, including OXR1, TXNRD1, and PRDX family genes. We further conducted in silico phylogenetic footprinting analysis of promoter regions. These results suggested that transcription factors such as acute myeloid leukemia-1a and cyclic adenosine monophosphate response element-binding protein may be involved in the observed upregulation of antioxidative genes. Our results support the idea that CSEs are strong candidate sources of antioxidant materials and cosmeceutically effective ingredients.

  9. The Concept of Work in Yupik Eskimo Society Before and After the Russian Influx: A Linguist’s Perspective

    Directory of Open Access Journals (Sweden)

    Nikolai Vakhtin

    2017-06-01

    Full Text Available The Yupik language has a word to signify ‘work’ derived from the stem qepgha(gh- (qepghaq ‘work’ [noun], qepghaghtuq ‘he works’, qepghaghta ‘worker’, etc. The scope of the meaning of this word changed drastically after the Russians came to Chukotka to stay in the 1930s. While in the pre-(intensive contact times the word mainly meant ‘house work’ or ‘processing the carcass of a killed animal’, in mid-20th century it acquired new meanings, borrowing them from Russian. The usage of the word also became a replica of Russian usage: the concept acquired new dependent words, like evaluative adverbs and adjectives, or inanimate agents. This change of meaning reflected social changes that took place in the Yupik world as a result of the modernisation process of the 1950s and 1960s, and is an indicator of the deep transformation the society underwent under Russian (Soviet influence. The paper analyses this process using two sources from two different epochs: Yupik texts recorded by Yekaterina Rubtsova in the 1940s, that is, in the pre-(intensive contact period, and a modern Russian-Yupik dictionary compiled by Natalia Rodionova, a teacher of Yupik Eskimo at the Anadyr college, and published 70 years later, in 2014.

They are high-yield and can be acquired through noninvasive methods from adult tissues. Moreover, they are nontumorigenic and are the most widely studied. On the other hand, induced pluripotent stem (iPS cells can be derived directly from adult cells through gene reprogramming. The new iPS technology avoids the embryo destruction or manipulation to generate pluripotent cells, therefore, are exempt from ethical implication surrounding embryonic stem cell use. The pre-differentiation of iPS cells ensures the safety of future approaches. Both mesenchymal stem cells and iPS cells can be used for autologous cell transplantations without the risk of immune rejection and represent a great opportunity for future alternative therapies.

  12. Measuring meaningful learning in the undergraduate chemistry laboratory

    Galloway, Kelli R.

    The undergraduate chemistry laboratory has been an essential component in chemistry education for over a century. The literature includes reports on investigations of singular aspects laboratory learning and attempts to measure the efficacy of reformed laboratory curriculum as well as faculty goals for laboratory learning which found common goals among instructors for students to learn laboratory skills, techniques, experimental design, and to develop critical thinking skills. These findings are important for improving teaching and learning in the undergraduate chemistry laboratory, but research is needed to connect the faculty goals to student perceptions. This study was designed to explore students' ideas about learning in the undergraduate chemistry laboratory. Novak's Theory of Meaningful Learning was used as a guide for the data collection and analysis choices for this research. Novak's theory states that in order for meaningful learning to occur the cognitive, affective, and psychomotor domains must be integrated. The psychomotor domain is inherent in the chemistry laboratory, but the extent to which the cognitive and affective domains are integrated is unknown. For meaningful learning to occur in the laboratory, students must actively integrate both the cognitive domain and the affective domains into the "doing" of their laboratory work. The Meaningful Learning in the Laboratory Instrument (MLLI) was designed to measure students' cognitive and affective expectations and experiences within the context of conducting experiments in the undergraduate chemistry laboratory. Evidence for the validity and reliability of the data generated by the MLLI were collected from multiple quantitative studies: a one semester study at one university, a one semester study at 15 colleges and universities across the United States, and a longitudinal study where the MLLI was administered 6 times during two years of general and organic chemistry laboratory courses.

    Ozone and water are powerful tracers of photochemical processes on Mars. Considering that water is a condensable with a multifaceted hydrological cycle and ozone is continuously being produced / destroyed on short-time scales, their maps can test the validity of current 3D photochemical and dynamical models. Comparisons of modern GCM models (e.g., Lefèvre et al. 2004) with certain datasets (e.g., Clancy et al. 2012; Bertaux et al. 2012) point to significant disagreement, which in some cases have been related to heterogeneous (gas-dust) chemistry beyond the classical gas-gas homogeneous reactions.We address these concerns by acquiring full 2D maps of water and ozone (via O2 dayglow) on Mars, employing high spectral infrared spectrometers at ground-based telescopes (CRIRES/VLT and CSHELL/NASA-IRTF). By performing a rotational analysis on the O2 lines, we derive molecular temperature maps that we use to derive the vertical level of the emission (e.g., Novak et al. 2002). Our maps sample the full observable disk of Mars on March/25/2008 (Ls=50°, northern winter) and on Jan/29/2014 (Ls=83°, northern spring). The maps reveal a strong dependence of the O2 emission and water burden on local orography, while the temperature maps are in strong disagreement with current models. Could this be the signature of heterogeneous chemistry? We will present the global maps and will discuss possible scenarios to explain the observations.This work was partially funded by grants from NASA's Planetary Astronomy Program (344-32-51-96), NASA’s Mars Fundamental Research Program (203959.02.02.20.29), NASA’s Astrobiology Program (344-53-51), and the NSF-RUI Program (AST-805540).

    This exploratory study examined three instructional strategies used with female high school biology students. The relative contributions of the strategies to student understanding of microbiology and motivation in science were analyzed. The science education community targeted underachievement in science by implementing changes in content and practices (NRC, 1996). Research suggested that teachers facilitate learnirig environments based on human constructivism (Mintzes, Wandersee, & Novak, 1997) that is rooted in meaningful learning theory (Ausubel, Novak & Hanesian, 1978). Teachers were advised to use both visual and verbal instructional strategies (Paivio, 1983) and encourage students to construct understandings by connecting new experiences to prior knowledge. The American Society for Microbiology supports the study of microorganisms because of their prominence in the biosphere (ASK 1997). In this study, two participating teachers taught selected microbiology concepts while focused on the cutting edge science of biofilms. Biology students accessed digitized biofilm images on an ASM web page and adapted them into products, communicated with biofilm researchers, and adapted a professional-quality instructional video for cross-age teaching. The study revealed improvements in understanding as evidenced on a written test; however, differences in learnirig outcomes were not significant. Other data, including student journal reflections, observations of student interactions, and student clinical interviews indicate that students were engaged in cutting edge science and adapted biofilm images in ways that increased understanding of microbiology (with respect to both science content and as a way of knowing) and motivation.

    The sawtooth period in JET ELM-free H-Mode plasmas is increasing with Neutral Beam Injection (NBI) power. For injected power PNBI 12MW no large sawtooth crash is observed during the ELM-free period. However, as the edge stability is improved and external kink modes and ELMs are delayed, a possible sawtooth crash at a high plasma beta becomes a concern. In JET DT experiments, delaying sawteeth was found to be crucial in the quest for high fusion power. Fast particles are known to provide stabilizing effect on sawteeth, however, sawtooth stabilization by NBI ions is not clearly understood, since NBI ions are usually not ''fast'' enough to stabilize the m/n = 1/1 internal kink mode which is believed to cause the crash. In order to understand the observed sawteeth stabilization in tokamak experiments with NBI heating, the internal kink m/n = 1/1 mode stability of JET plasmas was modeled using the NOVA-K code, which is also benchmarked with the nonperturbative version of NOVA and the M3D code. Comparison of m/n = 1/1 mode stabilization by NBI ions in JET and TFTR and application of the nonlinear stabilization criteria is given

    This cross-age study explored the structural complexity and propositional validity of knowledge about and attitudes toward sharks, and the relationships among knowledge and attitudes. Responses were elicited from a convenience sample of students (5th, 8th and 11th grade, and college level) and senior citizens (n = 238). All subjects constructed a concept map on sharks and responded to a Likert-type attitude inventory. Based on the work of Novak and Gowin (Leaning How to Learn, Cambridge University Press, 1984), concept maps were scored for frequencies of non-redundant concepts and scientifically valid relationships, levels of hierarchy, incidence of branching and number of crosslinks. The attitude inventory, emerging from Kellert's (The Value of Life: Biological Diversity and Human Society, Island Press, 1996) work, generated subscale scores on four affective dimensions: scientific, naturalistic, moralistic and utilitarian/negative. Significant differences were found among subject groups on all knowledge structure variables and attitudinal dimensions. Gender differences were documented on three of four attitude subscales. A series of simple, mulitiple and canonical correlations revealed moderately strong relationships between knowledge structure variables and attitudinal dimensions. The pattern of these relationships supports conservation education efforts and instructional practices that encourage meaningful learning, knowledge restructuring and conceptual change (Mintzes et al., Assessing Science Understanding: A Human Constructivist View, Academic Press, 2000).

    Experimental and theoretical studies on the structure of several complexes based on (R)-3,3'-Br(2)-BINOL ligand and group (IV) metals used as catalysts in an enantioselective Friedel-Crafts alkylation of indoles with α,β-unsaturated ketones have been carried out. NMR spectroscopic studies of these catalysts have been performed, which suggested that at room temperature the catalysts would form a monomeric structure in the case of Ti(IV) and a dimeric structure in the cases of Zr(IV) and Hf(IV). Density functional theory (DFT) calculations clearly corroborate the conclusions of these experimental spectroscopic studies. The dimeric structure with a doubly bridged motif [Zr(IV)(2)(μ-(R)-3,3'-Br(2)-BINOL)(2)] where each binaphthol ligand acts as bridge between the metal centers (Novak's model) is more stable than the dimeric structure with a doubly bridged motif [Zr(IV)(2)(μ-O(t)Bu)(2)] where the tert-butoxide groups act as bridging ligands (Kobayashi's model). The scope of the Friedel-Crafts alkylation with regard to the indole structure has been studied. Finally a plausible mechanism for the Friedel-Crafts reaction and a stereomodel for the mode of action of the catalyst that explain the observed stereochemistry of the reaction products have been proposed.

  20. Energetic particle physics with applications in fusion and space plasmas

    1997-01-01

    Energetic particle physics is the study of the effects of energetic particles on collective electromagnetic (EM) instabilities and energetic particle transport in plasmas. Anomalously large energetic particle transport is often caused by low frequency MHD instabilities, which are driven by these energetic particles in the presence of a much denser background of thermal particles. The theory of collective energetic particle phenomena studies complex wave-particle interactions in which particle kinetic physics involving small spatial and fast temporal scales can strongly affect the MHD structure and long-time behavior of plasmas. The difficulty of modeling kinetic-MHD multiscale coupling processes stems from the disparate scales which are traditionally analyzed separately: the macroscale MHD phenomena are studied using the fluid MHD framework, while microscale kinetic phenomena are best described by complicated kinetic theories. The authors have developed a kinetic-MHD model that properly incorporates major particle kinetic effects into the MHD fluid description. For tokamak plasmas a nonvariational kinetic-MHD stability code, the NOVA-K code, has been successfully developed and applied to study problems such as the excitation of fishbone and Toroidal Alfven Eigenmodes (TAE) and the sawtooth stabilization by energetic ions in tokamaks. In space plasmas the authors have employed the kinetic-MHD model to study the energetic particle effects on the ballooning-mirror instability which explains the multisatellite observation of the stability and field-aligned structure of compressional Pc 5 waves in the magnetospheric ring current plasma

    The aim of this study was to examine stressors, coping, and coping effectiveness as a function of gender, type of sport, and skill. The sample consisted of 749 undergraduate athletes (455 males, 294 females) aged 18-38 years (mean= 19.8 years). Skill was classified as international/national, county, university, and club standard. Participants completed a stressor and coping concept map (Novak & Gowin, 1984). The results revealed gender, type of sport, and skill differences in relation to stressor frequencies, coping strategy deployment, and coping effectiveness. In contrast to previous research, females used a variety of problem-focused (e.g. planning, communication, technique-orientated coping) strategies more frequently than males. Team sport athletes reported a variety of sport-specific stressors relating to the demands of playing in a team environment. The group of national/international athletes reported using more planning, blocking, and visualization, and also reported that their coping was more effective than that of less-skilled athletes.

    Black young men who have sex with men (BYMSM) experience higher human immunodeficiency virus (HIV) incidence than their white and Latino counterparts. The aim of our study was to understand BYMSM's preferences for mobile phone-based HIV prevention and treatment in order to inform culturally tailored interventions to reduce the spread of HIV and improve HIV treatment outcomes in this population. Qualitative focus groups (N=6) with BYMSM aged 18-29 years (N=41; 46%, 19/41 HIV-positive) were conducted to elucidate their preferences for the design and delivery of mobile phone-based HIV prevention and treatment interventions. A modified grounded theory approach to data analysis was undertaken using ATLAS.ti textual analysis software. Participants preferred holistic health interventions that did not focus exclusively on HIV prevention and treatment. Issues of privacy and confidentiality were paramount. Participants preferred functionality that enables discreet connections to culturally competent health educators and treatment providers who can address the range of health and psychosocial concerns faced by BYMSM. Mobile phone-based HIV prevention has the potential to increase engagement with HIV prevention and treatment resources among BYMSM. For these approaches to be successful, researchers must include BYMSM in the design and creation of these interventions. ©Ian W Holloway, Terrell JA Winder, Charles Herbert Lea III, Diane Tan, Donte Boyd, David Novak.

    We propose a model, denoted here by 1.5D, to study energetic particle (EP) interaction with toroidal Alfvenic eigenmodes (TAE) in the case where the local EP drive for TAE exceeds the stability limit. Based on quasilinear theory, the proposed 1.5D model assumes that the particles diffuse in phase space, flattening the pressure profile until its gradient reaches a critical value where the modes stabilize. Using local theories and NOVA-K simulations of TAE damping and growth rates, the 1.5D model calculates the critical gradient and reconstructs the relaxed EP pressure profile. Local theory is improved from previous study by including more sophisticated damping and drive mechanisms such as the numerical computation of the effect of the EP finite orbit width on the growth rate. The 1.5D model is applied on the well-diagnosed DIII-D discharges no. 142111 [M. A. Van Zeeland et al., Phys. Plasmas 18, 135001 (2011)] and no. 127112 [W. W. Heidbrink et al., Nucl. Fusion. 48, 084001 (2008)]. We achieved a very satisfactory agreement with the experimental results on the EP pressure profiles redistribution and measured losses. This agreement of the 1.5D model with experimental results allows the use of this code as a guide for ITER plasma operation where it is desired to have no more than 5% loss of fusion alpha particles as limited by the design.

  7. Towards a more sonically inclusive museum practice: a new definition of the ‘sound object’

    Full Text Available As museums continue to search for new ways to attract visitors, recent trends within museum practice have focused on providing audiences with multisensory experiences. Books such as 2014’s The Multisensory Museum present preliminary strategies by which museums might help visitors engage with collections using senses beyond the visual. In this article, an overview of the multisensory roots of museum display and an exploration of the shifting definition of ‘object’ leads to a discussion of Pierre Schaeffer’s musical term objet sonore – the ‘sound object’, which has traditionally stood for recorded sounds on magnetic tape used as source material for electroacoustic musical composition. A problematic term within sound studies, this article proposes a revised definition of ‘sound object’, shifting it from experimental music into the realm of the author’s own experimental curatorial practice of establishing The Museum of Portable Sound, an institution dedicated to the collection and display of sounds as cultural objects. Utilising Brian Kane’s critique of Schaeffer, Christoph Cox and Casey O’Callaghan’s thoughts on sonic materialism, Dan Novak and Matt Sakakeeny’s anthropological approach to sound theory, and art historian Alexander Nagel’s thoughts on the origins of art forgery, this article presents a new working definition of the sound object as a museological (rather than a musical concept.

    The focus of this work lies on the enhancement of the magnetic properties of the ferromagnetic semiconductor Gallium manganese arsenide (GaMnAs), which is a basic material for the research in spintronics: It is told, how a high sample reproducibility and a strong control over the growth process can be gained by applying band edge spectroscopy and a special procedure for the material flux calibration. Also the most important methods for the electrical characterization of GaMnAs are discussed in a critical manner by showing that the anomalous Hall Effect contributes significantly to the Hall resistance even at room temperature and that Novak's method for the termination of the Curie-temperature provides correct values for layers with low defect concentration. Furthermore it is reported on the considerable enlargement of the useable parameter space of GaMnAs which was enabled by the enhanced control over the growth process: It was possible to grow layers with a very high Manganese content of 22% and Curie temperatures of 172 K and even once were produced which showed a strong magnetic moment despite an insulating behaviour at low temperatures. A last key aspect is the growth and characterization of ultra-thin GaMnAs layers, giving prospects for gating experiments or experiments on the proximity effect as these layers combine high Curie temperatures with insulating behaviour.

    Full Text Available Objective: The objective of this research was to evaluate the feasibilityand the diagnostic properties of hysteroscopy in a population of womenduring menacme with the complaint of abnormal uterine bleeding,comparing endoscopic with histological findings. Methods: The studywas retrospectively conducted in 314 outpatients submitted tohysteroscopy. Every woman was submitted to guided endometrialbiopsy, using a 3 or 5mm-diameter Novak curette. The hysteroscopesused were of 3 or 5mm caliber which image was reproduced in ascreen by means of an endocamera. The results of hysteroscopic andhistological exams were compared. Results: There were noabnormalities of the uterine cavity in 151 patients (48%. Submucousmyoma was the most frequent alteration found in 45 women (14.3%.Malignancy was detected in nine patients, out of which seven hadhistological confirmation. Sensibility and specificity of hysteroscopywere respectively: a 86.3% and 75.9% for abnormal uterine cavity; b100% and 99.4% for malignancy, and c 57.7% and 88.5% for endometrialhyperplasia. Five patients (6.6% were not submitted to hysteroscopydue to cervical stenosis. Two percent of the cases presented vagalreactions, such as sweating, nausea and dizziness, with short-timerecovery. Conclusions: For higher sensitivity and specificity, diagnostichysteroscopy should be complemented with histology of theendometrial biopsy. This procedure should be considered in the workupof patients at menacme with complaints of abnormal uterinebleeding.

    Full Text Available This paper contains reflections and results of a research that aimed to apply and analyze the use of concept maps in Higher Education as an indicator of significant learning concerning derivative as mathematical object with students that finished Differential and Integral Calculus. This is a qualitative approach, situated in the area of mathematics education, based on Ausubel's Theory of Meaningful Learning and on technique of Novak's Concept Mapping. As data acquisition instruments, use of classroom observations, questionnaire, brainstorming and digital conceptual mapping, made by an undergraduate physics course. To analyze we defined four aspects to be observed in the maps constructed by students: (i validity of propositions formed with concepts, (ii hierarchization, (iii cross-links between the propositions, and (vi the presence of applications. The identification of these elements, taken as reference to analyze the maps, allowed the collection of information about how each student has structured and correlated the set of concepts learned on the derivative of a function along their course. Based on the results, we have identified in the digital conceptual maps effective tools to evaluate the students in terms of meaningful learning about specific contents of Differential and Integral Calculus by the hierarchy of concepts, progressive differentiation and integrative reconciliation as defined in the Theory of Meaningful Learning.

    To determine the implantation success of local endometrial injury in patients undergoing intrauterine insemination following ovulation induction with gonadotropins as an infertility treatment. In this prospective randomized controlled trial, ovulation induction was performed with gonadotropins in 80 patients following intrauterine insemination. In 40 patients, local endometrial injury (scratch) was performed in the midluteal phase of the cycle preceding ovarian stimulation with a Novak curette to the posterior side of the endometrial cavity. Fifteen pregnancies (37.5%) and 11 clinical pregnancies (27.5%) occurred in the intervention group, whereas eight pregnancies (20%) and five clinical pregnancies (12.5%) occurred in the control group. Although the pregnancy rates and clinical pregnancy rates were increased in the intervention group, no statistically significant difference was found between the intervention and control groups (pregnancy rates: P=0.084; clinical pregnancy rates: P=0.094). Performing local endometrial injury (scratch) in the cycle preceding ovulation induction in patients with a diagnosis of infertility and indication for intrauterine insemination increased the pregnancy and clinical pregnancy rates. This increase was not, however, statistically significant. More randomized, controlled, prospective studies with larger patient numbers are required before the use of iatrogenic induction of local endometrial injury can be recommended in routine clinical practice.

    The Z/EG transgenic mouse line, produced by Novak et al., displays tissue-specific EGFP expression after Cre-mediated recombination. The autofluorescence of EGFP allows the visualization of cells of interest displaying Cre recombination. The initial construct was designed such that cells without Cre recombination express the beta-galactosidase marker, facilitating counterselection. We used inverse PCR to identify the site of integration of the Z/EG transgene, to improve the efficiency of homozygous Z/EG mouse production. Recombined cells produced large amounts of EGFP protein, resulting in higher levels of fluorescence and therefore greater contrast with nonrecombined cells. We mapped the transgene to the G1 region of chromosome 5. This random insertion was found to have occurred 230-bp upstream from the start codon of the Rasa4 gene. The insertion of the Z/EG transgene in the C57BL/6 genetic background had no effect on Rasa4 expression. Homozygous Z/EG mice therefore had no obvious phenotype. (c) 2009 Wiley-Liss, Inc.

    Drainage systems must be designed in a way to minimize undesired problems such as decrease in hydraulic capacity of the channel, blockage and transport of pollutants due to deposition of sediment. Channel design considering self-cleansing criteria are used to solve the sedimentation problem. Incipient deposition is one of the non-deposition self-cleansing design criteria that can be used as a conservative method for channel design. Experimental studies have been carried out in five different cross-section channels, namely trapezoidal, rectangular, circular, U-shape and V-bottom. Experiments were performed in a tilting flume using four different sizes of sands as sediment in nine different channel bed slopes. Two well-known methods, namely the Novak & Nalluri and Yang methods are considered for the analysis of sediment motion. Equations developed using experimental data are found to be in agreement with the literature. It is concluded that the design velocity depends on the shape of the channel cross-section. Rectangular and V-bottom channels need lower and higher incipient deposition velocities, respectively, in comparison with other channels.

    The self-excited ionization waves was observed in the Ne positive column. The experiments were made for Ne gas from 0.07 to 1.0 Torr, with the magnetic field from 0 to 3.33 kG. The discharge current were 10 to 300 mA. The longitudinal magnetic field was made by an air-core solenoid coil. The axial electric field was measured by two wall probes. The frequency, wave length and amplitude of waves were measured with a photo multiplier. It was found that the longitudinal magnetic field caused new self-excited ionization waves. The frequency of these waves decreased monotonously with increasing field. The behaviors of the wave length and amplitude were complicate, and the cause of these phenomena is related to the ionization waves due to the spatial resonance of electron gas, namely s-waves, p-waves and fluid γ-waves. The threshold of the magnetic field to cause the ionization waves increased with increasing gas pressure, and with decreasing discharge current in the range 0.07 to 0.44 Torr. The frequency of the self-excited ionization waves occurred at zero field was almost constant in the field-frequency relation. A simple dispersion equation was derived, and the Novak constant can be introduced. (J.P.N.)

    Full Text Available The aim of the study was to identify initial meanings of the concept of the gene among 50 students from the career training of teachers of biology at the University Pedagogical Experimental Libertador (UPEL, Pedagogical Institute of Caracas, who enrolled in Cell Biology (BC and General Genetics (GG, as well as those built from a didactic intervention that formed part of Participatory Action Research (PAR. The work is based on the Theory of Meaningful Learning of Ausubel, on the principles of critical meaningful learning facilitators of Moreira, and on elements of the educational act of Novak. To investigate the evolution of meaning of this concept were used: questionnaires, interviews, maps and graphic representations of concepts developed by students. The data analysis provides a differentiated evolution of the meaning of the gene in the students, which corresponds to the didactic intervention and teachers, actions in both courses. It shows the importance of organizing the teaching in a potentially meaningful way to reflect on the content and learning, so that abstract concepts such as gene, must be presented with a critical and reflexive epistemology.

Essa temática é de fundamental importância para a compreensão da saúde oral, na medida em que oferece conceitos científicos importantes e fundamentais para o exercício da prática clínica e preventiva, bem como por ser objeto de estudo em várias disciplinas ao longo do curso de Odontologia. Para a análise da estrutura cognitiva, utilizou-se a estratégia de mapas conceituais proposta por Novak e fundamentou-se na teoria da Aprendizagem Significativa, de Ausubel. A análise dos mapas elaborados pelos estudantes possibilitou um estudo não só sobre a estrutura cognitiva e as concepções sobre saúde oral dos alunos, como também permitiu um diagnóstico do conhecimento em diversos aspectos relevantes à formação científica e profissional, apontando para a necessidade de se repensar o processo ensino-aprendizagem nos cursos de Odontologia.

Fertilized chicken eggs were divided into the following treatment groups: placebo, diamond NPs, graphite NPs, pristine graphene, small graphene oxide, large graphene oxide, and reduced graphene oxide. Experimental solutions at a concentration of 500 µg/mL were administrated into the egg albumin. Gross pathology and the rate of survival were examined after 5, 10, 15, and 20 days of incubation. After 20 days of incubation, blood samples were collected and the weight of the body and organs measured. The relative ratio of embryo survival decreased after treatment all treatments except diamond NPs. There was no correlation between the rate of survival and the ζ-potential or the surface charge of the CNPs in solution. Body and organ weight, red blood-cell morphology, blood serum biochemical parameters, and oxidative damage in the liver did not differ among the groups. These results indicate that CNPs can remain in blood circulation without any major side effects, suggesting their potential applicability as vehicles for drug delivery or active compounds per se. However, there is a need for further investigation of their properties, which vary depending on production methods and surface functionalization. Keywords: nanoparticles, diamond, graphite, graphene, toxicity, red blood cells, oxidative stress, surface charge

In this report, we studied the pharmacokinetics, toxicity, and therapeutic activity of ceftiofur–PHBV (ceftiofur–poly(3-hydroxybutyrate-co-3-hydroxyvalerate in rats. The pharmacokinetic study demonstrated a sustained release of ceftiofur into the bloodstream, with detectable levels over the minimum inhibitory concentration for at least 17 days after a single intramuscular injection of ceftiofur–PHBV (10 mg/kg weight. In addition, the toxicological evaluation of biochemical, hematological, and coagulation blood parameters at the therapeutic dose demonstrated the safety of ceftiofur–PHBV, with no adverse effects. In addition, ceftiofur–PHBV exhibited a therapeutic effect for a longer time period than the nonencapsulated ceftiofur in rats challenged with Salmonella Typhimurium. The slow release of ceftiofur from the ceftiofur–PHBV, its low toxicity in the blood parameters evaluated, and the efficacy in the rats infected with Salmonella Typhimurium make ceftiofur–PHBV a strong candidate for biotechnological applications in

Breast cancer is especially known for long asymptomatic periods, up to 25 years, with no evidence of the disease, followed by a relapse. Factors that determine the cell's decision to enter a dormant state and that control its duration remain unclear. In recent years, considerable progress has been made in understanding how tumor cells circulating in the blood interact and extravasate into secondary sites and which factors might determine whether these cells survive, remain dormant, or become macrometastases. The mechanisms of tumor cell dormancy are still not clear. Two different hypotheses are currently discussed: tumor cells persist either by completely withdrawing from the cell cycle or by continuing to proliferate at a slow rate that is counterbalanced by cell death. Because dormant disseminated tumor cells may be the founders of metastasis, one hypothesis is that dormant tumor cells, or at least a fraction of them, share stem cell-like characteristics that may be responsible for their long half-lives and their suggested resistance to standard chemotherapy. Therefore, knowledge of the biology of tumor cell dormancy may be the basis from which to develop innovative targeted therapies to control or eliminate this tumor cell fraction. In this review, we discuss biological mechanisms and clinical implications of tumor dormancy in breast cancer patients.Keywords: tumor dormancy, disseminated tumor cell, circulating tumor cell, targeted therapy

E-mail: natalia.gaeta@hotmail.com Pestivirus are responsible for reproductive disorders in sheep and, although they are widely studied in other countries, Brazil lacks information on the prevalence of virus in sheep flocks. To investigate the occurrence of pestiviruses in the State of São Paulo, 268 samples of serum sheep with a history of reproductive problems from 28 properties were collected. Using virusneutralization as the diagnostic technique, it was found two (1% positive animals, with antibody titer of 20, with both females showing a history of reproductive problems, one with neonatal death and another, showing uterine secretion. Two properties studied showed reactive animals (7%. In five of these (18%, bovine co-creation was observed. There were no associations between any reagent animals and the risk factors studied. This work is one of the pioneers in the study of the prevalence of anti-pestivirus antibodies in Brazilian sheep flocks. The low frequency and low viral titer observed suggest that pestivirus are not an important agent related to the presence of reproductive disorders in sheep herds.

When the study of sciences takes place without interaction with natural and technological phenomena, a huge gap in the education of students occurs. In this sense, the use of different resources such as models, observations, real and virtual experiments, animations, simulations, video classes, can arouse students' interest in the conceptual content, different from what occurs when the study permits only using conventional resources, as books and handouts.

    Full Text Available The essay is about brigand characters by the name of Grujica Novakovic, The Old Man Novak and Lemon the merchant. These epic heroes are representatives of freedom ideas which, in Tesan's poetic vision solve many difficult situations, sometimes even in humorous manner. The opposite sides are Turkish invaders such as Risnjanin Hadzija descript in the poem as ruthless robber and senseless person. Also, this essay makes a retrospective with other characters from Serbian heroic epics. Podrugovic, as the supreme master of spoken word, when creating the character of Grujica Novakovic, makes a wide spectrum of events and characters. Not only that the humour itself has a positive effect, but makes the most quality out of it. Comic culmination is achieved in the scene when brigand Grujca gets hold of Dzafer-beg's treasure. He does not act as a noble person in this situation, but as a brigand. Faced with huge challenge of shining gleam of golden coins, brigand nature could not be hidden. Still, Podrugovic's Grujica is a great man by keeping his word in any kind of situation. He is acting in such a manner even with the beauty Dzafer-begovica. Altogether, every brigand character out of the pen of this Hercegovic's poem writer contain high ethical standards, heroic glory and humour rarely seen in such a high glow. This is the reason his poetry is deeply accepted among common people and his character Grujica, a hero and a brigand outlaw, as an example of highly ethical person, a brigand and a noble hero.

    The impact of external irradiation mainly at metastable transitions on the propagation of ionization waves in the positive column of a neon a low discharge is investigated. Effects of hysteresis, regions of existence of moving striations and the static current/voltage characteristic depending on the external circuit and on the axial location of the applied irradiation are observed experimentally. The many published experimental contributions show that the presence of striations - either standing or moving - is the normal situation in the diffusion range of pressure and that the homogeneous (i.e. striation free) positive column is the exception existing only for a limited range of currents and pressures. A slight change of one or the other of these parameters results in a transition from the homogeneous column to one containing moving striations or vice versa. Different types of moving striations are known (p-,r- and s- waves) which differ in the product of wavelength λ and the electric field strength E (Novak-constant). It is assumed, that the metastable atoms are responsible for the appearance of p-waves and therefore the discharge was operated at a pressure of p 0 = 1,7 Torr-cm and dc-discharge currents i 0 = 1-20 mA. The length of the glass discharge tube was 1 = 500 mm with radius r 0 = 1 cm. A hollow cathode and a plane electrode were used. The external resistance was varied between 20 kOhm and 1 MOhm additionally. The radiation of suitable wavelength was generated by a second discharge tube with emissive electrodes operated at a pressure of about 5 Torr-cm and discharge currents between 0,5A and 2A. Two hollow mirrors where the open-quote radiation-tube close-quote was centered between, guaranteed a constant light intensity around the investigated tube

    This paper reports a data mapping construction aimed to subsidize the decision making process regarding institutional projects, at different levels of responsibility, at the Instituto de Engenharia Nuclear. The conception models a systemic and adaptive tool which is based on the concept mapping theory developed by Novak. The Instituto de Engenharia Nuclear (IEN) is a research center of the Comissão de Energia Nuclear (CNEN), an autarchy attached to Ministério da Ciência, Tecnologia, Inovações e Comunicações. The main focus of IEN is research and development of nuclear science and technology. The developed tool creates a more effective and accessible way of sharing information. However, beyond project data integration into a specific instrument, it also has the intent to compensate the consequences of the continued reduction of the number of workers at IEN over recent years. The recent CNEN management report, published in 2016, showed the problematic situation caused by the loss of workers, stressing the high number of pensions granted and to be granted in the near future. The loss of labor force, besides exposing the urgent need for optimizing knowledge management efforts, also sheds light into another problem: the need for grouping responsibilities among the remaining workers. In this respect, the tool developed helps to face this challenge, enhancing autonomy at different levels but preserving the institutional guidelines. To conclude the report, and in order to exemplify the method, the paper also describes the map construction relative an innovative project proposal in a joint development towards the nuclear area.

  16. Research into Success

    1997-12-01

    Full Text Available As competition is becoming ever more fierce, research into the prerequisites for success is gaining ground. By most people, success is perceived as an external phenomenon, but it is in fact the consequence of a person's readiness to perform in the world (of business. In the paper, Novak distinguishes between internal, external and group success. The essence of interna!success, which is the condition for the other two types of success, is assuming responsibility for, and exercising self-control over one's psychic phenomena. This in fact means that one needs to "reprogramme" the old patterns of behaviour and substitute them for the new, which leads to personality changes based on the understanding and acceptance of the self and others as they are. In realizing personal abilities, motives and goals, mental guiding laws must also be taken into account. Nowadays, the overall success of an organization is an important indicator of the quality of gro up work. The working patterns of individuals comply with the patterns used by his or her colleagues. When we do something for ourselves, we do it for others. In certain organizations, through accepted ways of communication all people become successful, and no body needs to be paid off. Employees wholly identify themselves with their organization, and vice versa. This three-part paradigm (I-Others-Community is the basis for various models of practical training for success, which are often idealized, but are primarily aimed at abolishing passivity and flaws in the system and its wider environment.

    The Scratch Collapse Test (SCT) is used to assist in the clinical evaluation of patients with ulnar nerve compression. The purpose of this study is to introduce the hierarchical SCT as a physical examination tool for identifying multilevel nerve compression in patients with cubital tunnel syndrome. A prospective cohort study (2010-2011) was conducted of patients referred with primary cubital tunnel syndrome. Five ulnar nerve compression sites were evaluated with the SCT. Each site generating a positive SCT was sequentially "frozen out" with a topical anesthetic to allow determination of both primary and secondary ulnar nerve entrapment points. The order or "hierarchy" of compression sites was recorded. Twenty-five patients (mean age 49.6 ± 12.3 years; 64 % female) were eligible for inclusion. The primary entrapment point was identified as Osborne's band in 80 % and the cubital tunnel retinaculum in 20 % of patients. Secondary entrapment points were also identified in the following order in all patients: (1) volar antebrachial fascia, (2) Guyon's canal, and (3) arcade of Struthers. The SCT is useful in localizing the site of primary compression of the ulnar nerve in patients with cubital tunnel syndrome. It is also sensitive enough to detect secondary compression points when primary sites are sequentially frozen out with a topical anesthetic, termed the hierarchical SCT. The findings of the hierarchical SCT are in keeping with the double crush hypothesis described by Upton and McComas in 1973 and the hypothesis of multilevel nerve compression proposed by Mackinnon and Novak in 1994.

Results: Among 778 patients treated for acute MI, there were 291 (37% women and 487 (63% men. Forty-five patients (6% died during hospitalization, mostly due to cardiogenic shock. An association was found between early intrahospital mortality and the following risk factors: age >70 years, female sex, previous MI, and smoking. Median pain-to-call time was 2 hours, and median time from the onset of pain to arrival into the CCU was 4 hours. There were 59 (7.6% patients admitted to the CCU within recommended 90 minutes. Diabetic comorbidity was not associated with early death or with longer time from pain to emergency calls. Conclusion: Some of the risk factors associated with adverse outcomes in MI are modifiable. Prehospital delay of 4 hours observed in patients who suffered an MI is too long, and more effort should be devoted to investments in health care and education of the general public regarding chest pain symptoms.

  20. Relation Between the Cell Volume and the Cell Cycle Dynamics in Mammalian cell

    Magno, A.C.G.; Oliveira, I.L.; Hauck, J.V.S.

    2016-01-01

    The main goal of this work is to add and analyze an equation that represents the volume in a dynamical model of the mammalian cell cycle proposed by Gérard and Goldbeter (2011) [1]. The cell division occurs when the cyclinB/Cdkl complex is totally degraded (Tyson and Novak, 2011)[2] and it reaches a minimum value. At this point, the cell is divided into two newborn daughter cells and each one will contain the half of the cytoplasmic content of the mother cell. The equations of our base model are only valid if the cell volume, where the reactions occur, is constant. Whether the cell volume is not constant, that is, the rate of change of its volume with respect to time is explicitly taken into account in the mathematical model, then the equations of the original model are no longer valid. Therefore, every equations were modified from the mass conservation principle for considering a volume that changes with time. Through this approach, the cell volume affects all model variables. Two different dynamic simulation methods were accomplished: deterministic and stochastic. In the stochastic simulation, the volume affects every model's parameters which have molar unit, whereas in the deterministic one, it is incorporated into the differential equations. In deterministic simulation, the biochemical species may be in concentration units, while in stochastic simulation such species must be converted to number of molecules which are directly proportional to the cell volume. In an effort to understand the influence of the new equation a stability analysis was performed. This elucidates how the growth factor impacts the stability of the model's limit cycles. In conclusion, a more precise model, in comparison to the base model, was created for the cell cycle as it now takes into consideration the cell volume variation (paper)

    Full Text Available Objective: To assess the value of diagnostic hysteroscopy with biopsy in the preoperative preparation for endometrial ablation. Methods: It was a prospective non-randomized study conducted at the division of Gynecologic Endoscopy of Hospital do Servidor Público Estadual “Francisco Morato de Oliveira” from March 2007 to May 2009. A total of 45 patients with abnormal uterine bleeding, and referred to endometrial ablation were included. All women underwent a diagnostic hysteroscopy, and were treated with a GnRH analogous – goserelin – 10.8 mg before surgery. The endometrial ablation was performed with a surgical resectoscope. Patients were submitted to one directed endometrial biopsy, one guided endometrial biopsy with Novak curette, and to endometrial ablation, which was considered as reference for pathological examination with samples from the biopsies. Data were analyze using the SPSS-v16 software, and considered significance at p = 0.05. Results: The mean age of women was 44.20 years (33-56, parity of 2.67 (0-9, uterus size of 139.99 calculated in cc (42-278, and the mean duration of symptoms was 3.68 years (0.5-15. The guided endometrial biopsy showed sensitivity of 80% for endometrium without atypia, and the directed endometrial biopsy had sensitivity of 60%. For proliferative endometrium the directed endometrial biopsy showed sensitivity of 76 and 100% for secretory endometrium, which was higher than the guided endometrial biopsy with 53 and 50%, respectively. Conclusion: The directed biopsy before endometrial ablation had lower sensitivity than guided biopsy for endometrium without atypia, however it was higher for proliferative and secretory endometrium.

    This paper presents the main features and results of the on-site dynamic tests and the related numerical analysis carried out for the PEC reactor vessel. The purpose is to provide an example of on-site testing of large components, stressing the problems encountered during the experiments, as well as in the processing phase of the test results and for the comparisons between calculations and measurements. Tests, performed by ISMES on behalf of ENEA, allowed the dynamic response of the empty vessel to be measured, thus providing data for the verification of the numerical models of the vessel supporting structure adopted in the PEC reactor-block seismic analysis. An axisymmetric model of the vessel, implemented in the vessel, implemented in the NOVAK code, had been developed in the framework of the detailed numerical studies performed by NOVATOME (again on behalf of ENEA), to check the beam schematization with fluid added mass model adopted by ANSALDO in SAP-IV and ANSYS for the reactor-block design calculations. Furthermore, a numerical model, describing vessel supporting structure in detail, was also developed by ANSALDO and implemented in the SAP-IV code. The test conditions were analysed by use of these and the design models. Comparisons between calculations and measurements showed particularly good agreement with regard to first natural frequency of the vessel and rocking stiffness of the vessel supporting structure, i.e. those parameters on which vessel seismic amplification mainly depends: this demonstrated the adequacy of the design analysis to correctly calculate the seismic motion at the PEC core diagrid.

    For the analyses of gate insulating materials of thin silicon oxy-nitride (SiON) and dielectric films, SIMS is one of the available tool along with TEM and ESCA, etc. Especially, to investigate the distribution of dopant in the thin films, SIMS is appreciably effective in these techniques because of its depth profiling capability and high sensitivity. One of the problem occurring in this SIMS measurement is the change of secondary ion yield at the interface as well as in the layers with different chemical composition. To solve this problem, some groups have researched the phenomenon for SiO 2 /Si interface [W. Vandervorst, T. Janssens, R. Loo, M. Caymax, I. Peytier, R. Lindsay, J. Fruhauf, A. Bergmaier, G. Dollinger, Appl. Surf. Sci. 203-204 (2003) 371-376; S. Hayashi, K.Yanagihara, Appl. Surf. Sci. 203-204 (2003) 339-342; M. Barozzi, D. Giubertoni, M.Anderle, M. Bersani, Appl. Surf.

In the present study, profiles of boron and matrix elements in the Si/SiON layers on Si substrate have been investigated. The sensitivity change of Si and B profiles in SiON layer become smaller by using oxygen flood than those without oxygen flood for both O 2 + and Cs + beam. At the range of 0-25 at.% of N composition, 11 B dosimetry in SiON layer implanted through amorphous Si depends on N composition. This trend could be caused by the sensitivity change of 11 B, or it indicates real 11 B concentration change in SiON lyaer. N areal density determined by Cs + SIMS with oxygen flooding also shows linear relationship with N composition estimated by XPS

    This paper reports a data mapping construction aimed to subsidize the decision making process regarding institutional projects, at different levels of responsibility, at the Instituto de Engenharia Nuclear. The conception models a systemic and adaptive tool which is based on the concept mapping theory developed by Novak. The Instituto de Engenharia Nuclear (IEN) is a research center of the Comissão de Energia Nuclear (CNEN), an autarchy attached to Ministério da Ciência, Tecnologia, Inovações e Comunicações. The main focus of IEN is research and development of nuclear science and technology. The developed tool creates a more effective and accessible way of sharing information. However, beyond project data integration into a specific instrument, it also has the intent to compensate the consequences of the continued reduction of the number of workers at IEN over recent years. The recent CNEN management report, published in 2016, showed the problematic situation caused by the loss of workers, stressing the high number of pensions granted and to be granted in the near future. The loss of labor force, besides exposing the urgent need for optimizing knowledge management efforts, also sheds light into another problem: the need for grouping responsibilities among the remaining workers. In this respect, the tool developed helps to face this challenge, enhancing autonomy at different levels but preserving the institutional guidelines. To conclude the report, and in order to exemplify the method, the paper also describes the map construction relative an innovative project proposal in a joint development towards the nuclear area.

    In this study, we describe a new semi-quantitative method for measuring the extent of bleeding in pathohistological tissue samples. To test our novel method, we recruited 120 female patients in their first trimester of pregnancy and divided them into three groups of 40. Group I was the control group, in which no dilation was applied. Group II was an experimental group, in which dilation was performed using classical mechanical dilators. Group III was also an experimental group, in which dilation was performed using a hydraulic dilator. Tissue samples were taken from the patients' cervical canals using a Novak's probe via energetic single-step curettage prior to any dilation in Group I and after dilation in Groups II and III. After the tissue samples were prepared, light microscopy was used to obtain microphotographs at 100x magnification. The surfaces affected by bleeding were measured in the microphotographs using the Autodesk AutoCAD 2009 program and its "polylines" function. The lines were used to mark the area around the entire sample (marked A) and to create "polyline" areas around each bleeding area on the sample (marked B). The percentage of the total area affected by bleeding was calculated using the formula: N = Bt x 100 / At where N is the percentage (%) of the tissue sample surface affected by bleeding, At (A total) is the sum of the surfaces of all of the tissue samples and Bt (B total) is the sum of all the surfaces affected by bleeding in all of the tissue samples. This novel semi-quantitative method utilizes the Autodesk AutoCAD 2009 program, which is simple to use and widely available, thereby offering a new, objective and precise approach to estimate the extent of bleeding in tissue samples.

    Full Text Available Abstract Background In 2009, Santa Isabel Province in the Solomon Islands embarked on a malaria elimination programme. However, very little is known in the Province about the anopheline fauna, which species are vectors, their bionomics and how they may respond to intensified intervention measures. The purpose of this study was to provide baseline data on the malaria vectors and to ascertain the possibility of successfully eliminating malaria using the existing conventional vector control measures, such as indoor residual spraying (IRS and long-lasting insecticidal nets (LLIN. Methods Entomological surveys were undertaken during October 2009. To determine species composition and distribution larval surveys were conducted across on the whole island. For malaria transmission studies, adult anophelines were sampled using human landing catches from two villages - one coastal and one inland. Results Five Anopheles species were found on Santa Isabel: Anopheles farauti, Anopheles hinesorum, Anopheles lungae, Anopheles solomonis, and Anopheles nataliae. Anopheles hinesorum was the most widespread species. Anopheles farauti was abundant, but found only on the coast. Anopheles punctulatus and Anopheles koliensis were not found. Anopheles farauti was the only species found biting in the coastal village, it was incriminated as a vector in this study; it fed early in the night but equally so indoors and outdoors, and had a low survival rate. Anopheles solomonis was the main species biting humans in the inland village, it was extremely exophagic, with low survival rates, and readily fed on pigs. Conclusion The disappearance of the two major vectors, An. punctulatus and An. koliensis, from Santa Isabel and the predominance of An. hinesorum, a non-vector species may facilitate malaria elimination measures. Anopheles farauti was identified as the main coastal vector with An. solomonis as a possible inland vector. The behaviour of An. solomonis is novel as it has

Health care providers were required to have experience prescribing or managing patients using canagliflozin to be included in the study. Health care providers compared canagliflozin with other T2DM medication classes on clinical characteristics, costs, and patient satisfaction. Confidence in canagliflozin was also measured. Health care providers reported their canagliflozin prescribing experience and good candidate characteristics for treatment. Finally, providers reported on patient outcomes among those receiving canagliflozin. All variables were compared across provider type.Results: Health care providers reported higher favorability for canagliflozin for blood pressure and body weight compared with dipeptidyl peptidase-4 (DPP-4 inhibitors and higher favorability for effect on blood pressure, body weight, treatment satisfaction, and glycosylated hemoglobin (HbA1c compared with sulfonylureas (SUs, with differences observed for effect on blood pressure. Health care providers reported being very/extremely confident (55%–74% with canagliflozin as a second- to fourth-line treatment. The top 3 characteristics reported by the providers, in terms of describing a good candidate for canagliflozin, include those concerned about their weight, insurance coverage/affordability, and avoiding injectable treatments.

    This online volume contains a selection of papers arising from two workshops organised within the six-month programme Topological Dynamics in the Physical and Biological Sciences held at the Isaac Newton Institute for Mathematical Sciences, Cambridge, from July to December 2012. The first of these was a 'satellite workshop' held at the International Centre for Mathematical Sciences (ICMS), Edinburgh, 15-19 October 2012, under the title Tangled Magnetic Fields in Astro- and Plasma Physics, and with Scientific Organising Committee: Konrad Bajer (Warsaw), Mitchell Berger (Exeter), Steve Cowley (Culham Centre for Fusion Energy), Andrew Gilbert (Exeter), Gunnar Hornig (Dundee), and Clare Parnell (St Andrews). The second was the workshop Quantised Flux in Tightly Knotted and Linked Systems held at the Newton Institute, 3- 7 December 2012, with Scientific Organising Committee: Natalia Berloff (DAMTP, Cambridge), Anne-Christine Davis (DAMTP, Cambridge), Jason Cantarella (University of Georgia), Thomas Kephart (Vanderbilt University), Paul Sutcliffe (Durham University), and Tanmay Vachaspati (Arizona State University). Videos of the lectures given at this second workshop can be viewed at http://www.newton.ac.uk/webseminars. The papers published here follow a natural progression through the following topics: helicity and related invariants of magnetic fields in ideal MHD; relaxation under topological constraints; lower bounds on magnetic energy; current and vortex filaments; applications in the solar corona, tokamak plasmas, and cyclone dynamics; higher-order invariants; topology of curves and surfaces, and energy measures; tight knots; applications to Bose-Einstein condensates, QCD, and cosmic superstring theory. Some of the papers span more than one of these areas. We owe a great debt of gratitude to Konrad Bajer, who was one of the guiding spirits behind the whole Newton Institute program, and who took particular responsibility for the Satellite Workshop at ICMS

Results: We found that FLIP7 demonstrated: high synergy (fractional inhibitory concentration index <0.25 with meropenem, amikacin, kanamycin, ampicillin, vancomycin and cefotaxime; synergy with clindamycin, erythromycin and chloramphenicol; additive interaction with oxacillin, tetracycline, ciprofloxacin and gentamicin; and no interaction with polymyxin B. The interaction in planktonic cell models was significantly weaker than in biofilms of the same strains. The analysis of the dose–effect curves pointed to persister cells as a likely target of FLIP7 synergistic effect. The biofilm eradication assay showed that the effect also caused total destruction of S. aureus and E. coli biofilm materials. The effect allowed reducing the effective anti-biofilm concentration of the antibiotic to a level well below the one clinically achievable (2–3 orders of magnitude in

As advanced PAP therapy modes (ie, auto-bilevel PAP [ABPAP] or adaptive servo-ventilation [ASV] may address these side effects, we hypothesized such treatment would be associated with decreased expiratory intolerance and increased adherence in posttraumatic stress patients with co-occurring OSA.Methods: We reviewed charts of 147 consecutive adult patients with moderately severe posttraumatic stress symptoms and objectively diagnosed OSA. All patients failed or rejected CPAP and were manually titrated on auto-adjusting, dual-pressure ABPAP or ASV modes in the sleep laboratory, a technique to eliminate flow limitation breathing events while resolving EPI. Patients were then prescribed either mode of therapy. Follow-up encounters assessed patient use, and objective data downloads (ODDs measured adherence.Results: Of 147 charts reviewed, 130 patients were deemed current PAP users, and 102 provided ODDs: 64 used ASV and 38 used ABPAP. ODDs yielded three groups: 59 adherent per insurance conventions, 19 subthreshold compliant partial users, and 24 noncompliant. Compliance based on available downloads was 58%, notably higher than recently reported rates in PTSD patients with OSA. Among the 19 partial users, 17 patients were minutes of PAP use or small percentages of nights removed from meeting insurance compliance criteria for PAP devices.Conclusion: Research is warranted on advanced PAP modes in

In the case of prehospital or early hospital conditions when factors such as urgency, stress, or inaccuracy of the undertaken activities are involved, the risk of causing complications, for instance, edema or postintubation injuries, increases, especially while dealing with a difficult intubation. The risk of improper inflation of the endotracheal tube cuff also increases, which is considered in this study.Objective: The aim of this study was to evaluate the prevalence of postintubation complications, such as postintubation injuries or edema, in a research sample, and to examine whether such complications occur more often, for example, while using a guidewire. In this study, we also evaluated the injuries associated with the inflation of the endotracheal tube cuff.Materials and methods: This study was performed on a group of 153 patients intubated in prehospital conditions. The tests were carried out in three clinical sites that received patients from prehospital care. Postintubation injuries were revealed and photographed using videolaryngoscope, such as the C-MAC and the McGrath series 5. The endotracheal tube cuff pressure was measured using a pressure gage manual (VBM Medizintechnik GmbH. The quantitative analyses of differences between incidence of variables were assessed using χ2 test for P<0.05. Analyses have been carried out using the Statistica software.Results: In the group of 153 patients, postintubation injuries occurred in 17% of cases. The dependency

    Rua, Melissa Jo

    The present study examined the understandings held by 5th, 8th, and 11th-grade students, their teachers and medical professionals about germs. Specifically, this study describes the content and structure of students' and adults' conceptions in the areas of germ contraction, transmission, and treatment of infectious and non-infectious diseases caused by microorganisms. Naturalistic and empirical research methods were used to investigate participants' conceptions. Between and within group similarities were found using data from concept maps on the topic "flu," drawings of germs, a 20 word card sort related to germs and illness, and a semi-structured interview. Concept maps were coded according to techniques by Novak and Gowan (1984). Drawings of germs were coded into four main categories (bacteria, viruses, animal cell, other) and five subcategories (disease, caricature, insect, protozoa, unclassified). Cluster patterns for the card sorts of each group were found using multidimensional scaling techniques. Six coding categories emerged from the interview transcripts: (a) transmission, (b) treatment, (c) effect of weather on illness, (d) immune response, (e) location of germs, and (f) similarities and differences between bacteria and viruses. The findings showed students, teachers and medical professionals have different understandings about bacteria and viruses and the structures of those understandings vary. Gaps or holes in the participants knowledge were found in areas such as: (a) how germs are transmitted, (b) where germs are found, (c) how the body transports and uses medicine, (d) how the immune system functions, (e) the difference between vaccines and non-prescription medicines, (f) differences that exist between bacteria and viruses, and (g) bacterial resistance to medication. The youngest students relied heavily upon personal experiences with germs rather than formal instruction when explaining their conceptions. As a result, the influence of media was

  6. Ways of incorporating photographic images in learning and assessing high school biology: A study of visual perception and visual cognition

    Nixon, Brenda Chaumont

    This study evaluated the cognitive benefits and costs of incorporating biology-textbook and student-generated photographic images into the learning and assessment processes within a 10th grade biology classroom. The study implemented Wandersee's (2000) 20-Q Model of Image-Based Biology Test-Item Design (20-Q Model) to explore the use of photographic images to assess students' understanding of complex biological processes. A thorough review of the students' textbook using ScaleMaster R with PC Interface was also conducted. The photographs, diagrams, and other representations found in the textbook were measured to determine the percentage of each graphic depicted in the book and comparisons were made to the text. The theoretical framework that guided the research included Human Constructivist tenets espoused by Mintzes, Wandersee and Novak (2000). Physiological and cognitive factors of images and image-based learning as described by Robin (1992), Solso (1997) and Wandersee (2000) were examined. Qualitative case study design presented by Yin (1994), Denzin and Lincoln (1994) was applied and data were collected through interviews, observations, student activities, student and school artifacts and Scale Master IIRTM measurements. The results of the study indicate that although 24% of the high school biology textbook is devoted to photographic images which contribute significantly to textbook cost, the teacher and students paid little attention to photographic images other than as aesthetic elements for creating biological ambiance, wasting valuable opportunities for learning. The analysis of the photographs corroborated findings published by the Association American Association for the Advancement of Science that indicated "While most of the books are lavishly illustrated, these representations are rarely helpful, because they are too abstract, needlessly complicated, or inadequately explained" (Roseman, 2000, p. 2). The findings also indicate that applying the 20-Q

    Theoretical calculation and numerical simulation indicate that there can be interesting interactions between alpha particles and MHD activity which can adversely affect the performance of a tokamak reactor (e.g., ITER). These interactions include alpha-driven MHD, like the toroidicity-induced-Alfven-eigenmode (TAE) and MHD induced alpha particle losses or redistribution. Both phenomena have been observed in recent TFTR DT experiments. Weak alpha-driven TAE activity was observed in a NBI-heated DT experiment characterized by high q0 ( >= 2) and low core magnetic shear. The TAE mode appears at ~30-100 ms after the neutral beam turning off approximately as predicted by theory. The mode has an amplitude measured by magnetic coils at the edge tildeB_p ~1 mG, frequency ~150-190 kHz and toroidal mode number ~2-3. It lasts only ~ 30-70 ms and has been seen only in DT discharges with fusion power level about 1.5-2.0 MW. Numerical calculation using NOVA-K code shows that this type of plasma has a big TAE gap. The calculated TAE frequency and mode number are close to the observation. (2) KBM-induced alpha particle loss^1. In some high-β, high fusion power DT experiments, enhanced alpha particle losses were observed to be correlated to the high frequency MHD modes with f ~100-200 kHz (the TAE frequency would be two-times higher) and n ~5-10. These modes are localized around the peak plasma pressure gradient and have ballooning characteristics. Alpha loss increases by 30-100% during the modes. Particle orbit simulations show the added loss results from wave-particle resonance. Linear instability analysis indicates that the plasma is unstable to the kinetic MHD ballooning modes (KBM) driven primarily by strong local pressure gradients. ----------------- ^1Z.

    Buchholz, Dilek

    The purpose of this qualitative, multiple case study of 14 students in a metropolitan public school in the Deep South was to find out, during a period of three months, what these kindergarten-aged children knew about birds, whether this knowledge represented current scientific thought, if such science instruction meaningfully affected their prior knowledge, and if so, what the factors during instruction that seemed to influence their understanding of the concept of bird were. The research was conducted in three phases; preinstruction interviews, instruction, and postinstruction interviews. The theoretical framework for this research was based on the Human Constructivism theory of learning (Mintzes, Wandersee and Novak, 1997). Instructional materials consisted of carefully chosen books (both fiction and non-fiction), guest speakers, field trips, a live bird in the classroom, students' observation journals, teacher-made classification and sorting activities, and picture-based concept maps. The findings suggest that young children's knowledge of birds was limited chiefly to birds' anatomical and morphological characteristics, with repeated references being made by the children to human characteristics. There was a positive, significant difference in young children's pre- and postinstruction scientific knowledge of birds. Although performance varied from child to child after instruction, most children were able to identify some common birds by name. Just one child resisted conceptual change. Kindergarten children's basic knowledge of bird behavior was limited to flight and eating. Although the children had more conceptual knowledge at the end, understanding still appeared to be shallow. The children did develop their skill in observing markedly. It also became evident that these kindergarten children needed more (a) experience in asking questions, (b) practice in techniques of visual representation, and (c) language development in order to be able to explain what they

A second aim was to assess the degree to which the risk of various types of opioid misuse (onset, desistance, and incidence of dependence was related to the longitudinal course of self-reported pain interference over the 3-year period. Methods: We used a two-wave, nationally representative sample of adults (aged 18+ years in which the baseline data were collected during 2001–2002 and a single follow-up was obtained ~3 years later (2004–2005 with 34,332 respondents with complete data on study variables for both waves. Results: Our findings indicated that ~10% reported high pain interference in the past month at each wave. There was tremendous stability in levels of pain, with ~5% reporting consistent levels of high impairment over the 3-year study, a proxy for chronic pain. Levels of pain were more strongly associated with prescription pain reliever misuse concurrently rather than prospectively, and the association was largely linear, with the likelihood of misuse increasing with levels of pain. Finally, health service factors were also prominent predictors of onset, but not the outcomes, of desistance or transitions to problem use. Conclusion: This study is the first to use a nationally representative sample with measures of pain and drug use history collected over an extended period. These results may help provide clinicians with an understanding that the risk of misuse is greatest when pain is active and may help guide the selection of

    1998-12-01

    Exploration of meaningful learning of the polymerase chain reaction (PCR) followed instruction by a researcher-developed hypermedia computer program that incorporated human constructivist principles and a "science-in-fiction" chapter of a novel that described PCR. Human constructivism is the Ausubel-Novak-Gowin (1997) meaningful learning theory that supports science learning through graphic representations and multiple examples. Science-in-fiction is a new genre of fiction introduced by the prominent scientist, Carl Djerassi, to engender an appreciation for science, and its ethical dilemmas. Chapter 19 of Djerassi's 1994 novel, The Bourbaki Gambit, was placed into hypermedia format to standardize the presentation. As part of a clinical microbiology course in the medical technology curriculum at a major medical center in the Deep South, 10 undergraduates participated in this study. Each first read The Bourbaki Gambit, and then half of the participants experienced the human constructivist approach first (the PCR group) while the others first encountered the science-in-fiction approach (the Chapter 19 group). For the rest, the order of presentation was reversed, so that all experienced both programs. Students' explanations while using the computer were videotaped. Students were tested and interviewed before experiencing either program, after their first instructional session, and again after the second instructional session. These students were also assessed on their knowledge of the nature of science by taking the Nature of Science Questionnaire, before and after instruction (Roach, 1993) and interviewed as a cross-check on its reliability. Students' preferred learning approaches were determined using Schmeck's Inventory of Learning Processes (Schmeck, Ribich, & Ramanaiah, 1977). Data were collected and analyzed both qualitatively and quantitatively using appropriate verbal analysis techniques (Chi, 1997). All but three students reached a structural level of PCR

    Mayor, E.; Velasco, A. M.; Martín, I.; Lavín, C.

    Los estados Rydberg moleculares han suscitado en los últimos años un creciente interés entre los espectroscopistas experimentales, motivado en parte por el desarrollo de nuevas técnicas espectroscópicas capaces de investigar estos estados altamente excitados electrónicamente. Los procesos de fotoabsorción que implican estados Rydberg en los derivados halogenados del metano son de gran importancia, debido a su abundancia en la atmósfera y a sus implicaciones medioambientales. Por ello, la obtención de datos relativos a sus fuerzas de oscilador es de gran interés. En este trabajo se aborda el estudio de dichas propiedades para las moléculas isovalentes CF3Cl y CF3Br. Ambas moléculas presentan idéntica estructura electrónica para el estado fundamental por lo que se espera que sus espectros Rydberg presenten grandes similitudes, en ausencia de perturbaciones. Por ello y dada la escasez de datos relativos a fuerzas de oscilador, hemos establecido la corrección de nuestros resultados en base a las analogías esperadas en las intensidades espectrales correspondientes a transiciones análogas. Por otro lado, Novak y col. [1] han encontrado experimentalmente un marcado carácter atómico en el espectro correspondiente a estas moléculas, siendo muy similar a los de los átomos de Cl y Br. Por ello en el presente trabajo, además de establecer la comparación entre ambas moléculas hemos buscado las similitudes con sus respectivos halógenos. Los cálculos relativos a las especies moleculares se han realizado utilizando la Metodología Molécular de Orbítales de Defecto Cuántico (MQDO) [2], mientras que para el estudio de los átomos de Cl y Br se empleó la versión relativista del método (RQDO) [3].

    Full Text Available The Didactic Networks proposed in this paper are based on previous publications in the field of the RSR (Rhetorical-Semantic Relations. The RSR is a set of primitive relations used for building a specific kind of semantic networks for artificial intelligence applications on the web: the RSN (Rhetorical-Semantic Networks. We bring into focus the RSR application in the field of elearning, by defining Didactic Networks as a new set of semantic patterns oriented to the development of elearning applications. The different lines we offer in our research fall mainly into three levels: (1 The most basic one is in the field of computational linguistics and related to Logical Operations on RSR (RSR Inverses and plurals, RSR combinations, etc, once they have been created. The application of Walter Bosma's results regarding rhetorical distance application and treatment as semantic weighted networks is one of the important issues here. (2 In parallel, we have been working on the creation of a knowledge representation and storage model and data architecture capable of supporting the definition of knowledge networks based on RSR. (3 The third strategic line is in the meso-level, the formulation of a molecular structure of knowledge based on the most frequently used patterns. The main contribution at this level is the set of Fundamental Cognitive Networks (FCN as an application of Novak's mental maps proposal. This paper is part of this third intermediate level, and the Fundamental Didactic Networks (FDN are the result of the application of rhetorical theory procedures to the instructional theory. We have formulated a general set of RSR capable of building discourse, making it possible to express any concept, procedure or principle in terms of knowledge nodes and RSRs. The Instructional knowledge can then be elaborated in the same way. This network structure expressing the instructional knowledge in terms of RSR makes the objective of developing web

    1999-11-01

    The main research question of this study was: What gaps in biochemical understanding are revealed by a range of university introductory biology students as they work through a critically acclaimed multimedia program on photosynthesis, and what are the corresponding implications for elaboration of the Ausubel-Novak-Gowin Learning Theory (ANG, now Human Constructivism)? Twelve students, mixed for ability, gender and ethnicity, were recruited from two sections of "Bio 101." Before and after instruction in photosynthesis, in-depth clinical interviews were conducted during which participants completed a range of cognitive tasks such as sorting, concept mapping, explaining and predicting. Some tasks involved interacting with a computer simulation of photosynthesis. This study primarily employed qualitative case study and verbal analysis methods. Verbal analysis of the clinical interviews revealed numerous gaps that were categorized into typologies. The two major categories were propositional gaps and processing gaps. Propositional gaps were evident in development of participants' concepts, links and constructs. Significant among these were conceptual distance gaps and continuity of matter gaps. Gaps such as convention gaps and relative significance gaps seem to be due to naivete in the discipline. Processing gaps included gaps in graphic decoding skills and relevant cognitive habits such as self-monitoring and consulting prior knowledge. Although the gaps were easier to detect and isolate with the above-average participants, all participants showed evidence of at least some of these gaps. Since some gaps are not unexpected at all but the highest literacy levels, not all the gaps identified are to be considered deficiencies. The gaps identified support the attention given by ANG theorists to the role of prior knowledge and metacognition as well as the value of graphic organizers in knowledge construction. In addition, this study revealed numerous gaps in graphic decoding

    Science instruction aims to ensure that students properly construct scientific knowledge so that each individual may play a role as a science literate citizen or as part of the science workforce (National Research Council, 1996, 2000). Students enter the classroom with a wide range of personal conceptions regarding science phenomena, often at variance with prevailing scientific views (Duschl, Hamilton, & Grandy, 1992; Hewson, 1992). The extensive misconceptions research literature emphasizes the importance of diagnosing students' initial understandings in order to gauge the accuracy and depth of what each student knows prior to instruction and then to use that information to adapt the teaching to address student needs. (Ausubel, 1968; Carey, 2000; Driver et al., 1985; Karplus & Thier, 1967; Mintzes, Wandersee, & Novak, 1998; Osborne & Freyberg, 1985; Project 2061, 1993; Strike & Posner, 1982, 1992; Vygotsky, 1934/1987). To gain such insight, teachers diagnose not only the content of the students' personal conceptions but also the thinking processes that produced them (Strike and Posner, 1992). Indeed, when teachers design opportunities for students to express their understanding, there is strong evidence that such diagnostic assessment also enhances science teaching and learning (Black & William, 1998). The functional knowledge of effective science teaching practice resides in the professional practitioners at the front lines---the science teachers in the classroom. Nevertheless, how teachers actually engage in the practice of diagnosis is not well documented. To help fill this gap, the researcher conducted a study of 16 sixth grade science classrooms in four Los Angeles area middle schools. Diagnostic teaching strategies were observed in action and then followed up by interviews with each teacher. Results showed that teachers use strategies that vary by the complexity of active student involvement, including pretests, strategic questions, interactive discussion

    Student nurses are provided with a great deal of knowledge within university, but they can find it difficult to relate theory to nursing practice. This study aimed to test the appropriateness and feasibility of assessing Novak's concept mapping as an educational strategy to strengthen the theory-practice link, encourage meaningful learning and enhance learning self-efficacy in nursing students. This pilot study utilised a mixed-methods quasi-experimental design. The study was conducted in a University school of Nursing in Hong Kong. A total of 40 third-year pre-registration Asian mental health nursing students completed the study; 12 in the concept mapping (CM) group and 28 in the usual teaching methods (UTM) group. The impact of concept mapping was evaluated thorough analysis of quantitative changes in students' learning self-efficacy, analysis of the structure and contents of the concept maps (CM group), a quantitative measure of students' opinions about their reflective learning activities and content analysis of qualitative data from reflective written accounts (CM group). There were no significant differences in self-reported learning self-efficacy between the two groups (p=0.38). The concept mapping helped students identify their current level of understanding, but the increased awareness may cause an initial drop in learning self-efficacy. The results highlight that most CM students were able to demonstrate meaningful learning and perceived that concept mapping was a useful reflective learning strategy to help them to link theory and practice. The results provide preliminary evidence that the concept mapping approach can be useful to help mental health nursing students visualise their learning progress and encourage the integration of theoretical knowledge with clinical knowledge. Combining concept mapping data with quantitative measures and qualitative reflective journal data appears to be a useful way of assessing and understanding the effectiveness of

    . The uncertainty relations for photon quadratures were also checked for the thermal photon state using experimental values of optical tomograms and avoiding the reconstruction procedure of the Wigner function and its associated precision constrains. In the tomographic-probability representation of quantum mechanics and quantum optics, tomograms are used for the description of quantum states as an alternative to the wave function and density matrix. The purity, fidelity, entropy and photon temperature associated with quantum states are expressed in terms of tomograms. This provides the possibility of measuring these characteristics directly by taking optical tomograms and checking basic inequalities like entropic uncertainty relations, temperature-dependent quadrature uncertainty relations, etc. The better understanding that quantum states can be identified with measurable probability distributions like optical tomograms opens new prospects in quantum optics, for example, to check experimentally the uncertainty relations for higher quadrature momenta and to control the precision with which the fundamental inequalities of quantum mechanics are experimentally confirmed. This Topical Issue is a collection of papers presented at the 17th Central European Workshops on Quantum Optics (CEWQO10) held at the University of St Andrews, Scotland, UK, 6-11 June 2010. The other collaborators from different scientific centers who could not, due to different reasons, come to St Andrews but participated in the previous CEWQOs and plan to participate in future CEWQOs also contributed to this issue.

    min. Under these conditions each analysis takes the student about 10 min and two students are scheduled per 20 min block. Since the instrument is under computer control, students operate the computer during the run. As the peaks appear on the mass chromatogram, their mass spectra are obtained and the student decides which corresponds to product and evaluates product purity and the structure of impurities. There is ample time to display all spectra, conduct library searches, and print data. This relatively simple laboratory exercise has the advantage of allowing each student to carry out an analysis on his or her own product. The fact that a brominated product is obtained introduces a discussion of isotopic patterns in mass spectrometry. The experiment is scheduled to coincide with the lecture discussion of spectroscopic structure determination and after SN2 reactions have been covered. One of our mass spectrometer satellite data stations is interfaced with a "3-gun" projector in a large lecture hall allowing the display of actual mass spectra from our instrument to lecture sections.

    O presente trabalho é parte preliminar de um estudo mais amplo em nível de doutorado sobre o ensino de astronomia mediado pelas tecnologias da informação e comunicação, utilizando dispositivos compactos, móveis e pessoais. Este estudo também faz parte do projeto institucional do CEFETMG sobre ambientes diversificados de aprendizagem sob fomento da agência estadual FAPEMIG (Fundação de Amparo à Pesquisa do Estado de Minas Gerais). Esta apresentação aborda o resultado das concepções prévias de estudantes em relação a conhecimentos básicos de astronomia, ligados à percepção e observação direta do céu. Três turmas de estudantes de 1ª série e uma turma de 3ª série do ensino integrado médio técnico da Educação Básica, Técnica e Tecnológica (EBTT) do CEFETMG Campus II - Belo Horizonte/MG foram submetidas a uma avaliação prévia através de questionário estruturado. Este questionário foi elaborado de forma a abordar a percepção dos estudantes em relação aos recursos gráficos (figuras e desenhos) representativos de conhecimentos básicos de astronomia, comuns em livros didáticos. Após a análise dos resultados desta avaliação, organizou-se uma estratégia de intervenção didática em sala de aula sobre o conteúdo de astronomia, utilizando-se de recursos de mediação baseados nas tecnologias da informação e comunicação. Os temas selecionados para esta estratégia didática foram relacionados aos assuntos básicos de astronomia em que ocorreu maior nível de desconhecimento dos estudantes. Os estudantes foram submetidos a avaliação posterior elaborada com os mesmos pressupostos da avaliação prévia. A análise dos resultados foi realizada a partir dos pressupostos da aprendizagem significativa (Ausubel; Novak e Hanesian, 1983). O ensino de astronomia por mediação das tecnologias da informação e comunicação indica uma alternativa preliminar aos trabalhos de campo usuais orientados na prática escolar, tais

    Croatian musical writers such as Lujo Šafranek-Kavić, Božidar Širola and Antun Dobronić. Their articles described activities of the Croatian National Theatre and evaluated new works of Croatian composers. But they were not at all remiss about acknowledging great masterpieces of European music being performed in Zagreb in their day, either. The works of Claude Debussy, Pelléas et Mélisande; Ludwig van Beethoven, Missa solemnis Richard Wagner, Lohengrin were also followed through reviews, albeit within a curious Croatian-paradigm of musical history which included musical and dramatic theatre from Ljubljana, Zagreb, Split, Sarajevo, Skoplje, Osijek. In other words, they seem to have been aware of the cultural differences without ignoring what from them were shared in common. Before the First World War, SLM classified Bulgarians together with Serbs, Croats and Slovenians, as the future "Yugoslav nation". When the reality of politics clouded their vision, the Magazine’s musical critics nevertheless pursued a troupe of Bulgarian performers to visit Belgrade, and thus added to their repertoire from works of Bulgarian composers. Among musical contributors to the journal were the eminently known "Yugoslavs", Dr Miloje Milojević (1884 - 1946 and Dr Viktor Novak (1889 - 1977. From Croatia and Slovenia musicians Juro Tkalčić and Ćiril Ličar, Milojević spoke about "our national artists" and praised musicians who, in their program, included compositions of "all Yugoslav nations". Dr Novak demanded that Belgrade become the musical capital of South Slavs, and invited Belgrade Opera to show on its scene the best Serbian, Croatian and Slovenian operas and ballets. From its onset, the Kingdom of Yugoslavia was burdened by heavy political and economical problems. That would also lead to bitter dispute about Yugoslavian ideology. Nevertheless, SLM did not renounce the system of its objectives and values upon which it was built. But there is one particular section where the

However, immunosuppressants are essential for the long-term survival of kidney grafts and patients’ non-adherence to their medication leads to poor outcomes. Immunosuppressants can also significantly alter patients’ HRQoL because of their side effects and the complex chronic medication regimen they represent. Purpose: To elicit key concepts related to adherence to immunosuppressant therapy (IT and reasons for non-adherence in terms of patient reported outcomes, side effects, and the impact of the medication on HRQoL in RT population, including patient preference of once daily over twice-daily immunosuppressive regimen. Results were used to develop an IT-specific conceptual framework and provide suggestions for improving patients’ adherence to IT. Materials and methods: Interviews were conducted with three clinical experts to determine key concepts related to RT and immunosuppressants. Thirty-seven participants in four focus groups were asked to cite important concepts related to adherence and impact of IT on HRQoL and to rate them. Qualitative analysis was conducted to code participants’ responses. Results: Non-adherence among participants where admitted was unintentional. The reason for this included forgetfulness, interference with lifestyle, being asleep at the time the medication should be taken, change in routine, and impact of side effects. Overall, participants reported that the evening dose was more problematic to remember

Previous studies have shown that gadolinium oxide (Gd2O3 nanoparticles generate higher relaxivity than currently available Gd chelates: In addition, the Gd2O3 nanoparticles have promising properties for MRI cell tracking. The aim of the present work was to study cell labeling with Gd2O3 nanoparticles in hematopoietic cells and to improve techniques for monitoring hematopoietic stem cell migration by MRI. Particle uptake was studied in two cell lines: the hematopoietic progenitor cell line Ba/F3 and the monocytic cell line THP-1. Cells were incubated with Gd2O3 nanoparticles and it was investigated whether the transfection agent protamine sulfate increased the particle uptake. Treated cells were examined by electron microscopy and MRI, and analyzed for particle content by inductively coupled plasma sector field mass spectrometry. Results showed that particles were intracellular, however, sparsely in Ba/F3. The relaxation times were shortened with increasing particle concentration. Relaxivities, r1 and r2 at 1.5 T and 21°C, for Gd2O3 nanoparticles in different cell samples were 3.6–5.3 s-1 mM-1 and 9.6–17.2 s-1 mM-1

There are significant differences for single-nucleotide polymorphism (SNP frequency. Materials and methods: We studied the peculiarities of P450 cytochrome polymorphisms, SLCO1B1 transporting protein, and P-glycoprotein carriage in healthy volunteers in the Nanai ethnic group living in Russia, and compared them to the carriage of SNPs in the Russian population according to literature data. Results: After performing the real-time polymerase chain reactions on the samples from 70 healthy volunteers from the Nanai group, for the CYP2C9*2C430T polymorphism we determined 70 CC-genotype carriers. As for the CYP2C9*3A1075C polymorphism, we found 62 AA-genotype carriers and eight AC-genotype carriers. For the CYP2C19*2G681A polymorphism, we determined 39 GG-genotype carriers and 28 GA-genotype carriers, for the CYP2C19*3G636A polymorphism 58 GG-genotype carriers and 12 GA-genotype carriers, and for the CYP2C19*17C806T polymorphism 67 CC-genotype carriers and three CT-genotype carriers. For the CYP2D6*4G1846A polymorphism, the GG genotype had 68 carriers, and the GA genotype two carriers. For the

    Full Text Available The interesting paper by Dinarvand and Vaisi-Raygan (1 makes valuable points about a particularly challenging aspect of biochemistry learning and teaching. Their work prompts me to ask two questions and make a comment. First, what do the authors mean by a concept map (CM? A pathway map could be considered a CM, but a CM could cover modes of regulation and kinetics in relation to particular reactions or pathways and there are many other possibilities. Irrespective of this, a CM can get extremely complex if more than a few concepts are involved (2, as can be seen in examples given by Novak (3. This is the fundamental problem of teaching and learning biochemistry (4, which combines the network of pathways, compartmentation, macromol¬ecular structure, regulation, kinetics and some fairly sophisticated chemical concepts.Second, how did the students go about preparing CMs? My experience is that students prefer to use a computer for most tasks, but standard CM software (5 may not be suitable. For example, they often struggle unnec¬essarily to use software to prepare a graphical summary of the structural features of a protein, its precursors and the gene encoding it. This distracts them from the material. My suggestions that pencil and paper might be sufficient are usually met with amazement. Third, as Dinarvand and Vaisi-Raygan (1 make clear, a coherent summary of the metabolism considered in a course in metabolic biochemistry is crucial if students are to appreciate the pathways and their interconn-ection and regulation. For many years I have used an approach in which students collaborate in tutorials to achieve this. The sessions are usually initiated by me drawing the plasma membrane and the mitochondrial membranes on a large board and inviting the students to fill in the blanks (I provide large sheets of paper so that students can make copies. With coaxing, someone volunteers and I explain that the volunteer is not alone because everyone is

    If I had to reduce all of educational psychology to just one principle, I would say this: The most important single factor influencing learning is what the learner already knows. Ascertain this and teach him accordingly. This famous quotation from David Ausubel in 1968 points out one of the fundaments for constructivism as theory of learning and knowledge, and states a still common held teaching approach. The first one found to investigate "what the learner already knows" about weather and climate elements, was the American pioneer psychologist Granville Stanley Hall in 1883, studying children of age 4 to 8. Since then many articles and books have been written on the same topics under different theories of learning, knowledge and teaching. Most outstanding are two books from Jean Piaget in 1926 and 1927, both including children's shifting ideas from age 3 to 12 about weather and climate elements and their causes. His books were the start of his lifelong work (till 1980) on what he called theory of Genetic Epistemology, another fundament of constructivism. Common features of Hall, Piaget and many other researches' discoveries are for instance that the youngest children (book chapters - often together with researchers from other countries. Common features of Hansen, Boyes and Stanisstreet and many other researchers' discoveries up to present, are that students on all levels still exchange or confuse the greenhouse effect with the effects of the ozone layer, and many thinks that the greenhouse effect is not necessary for life on the Erath. The greenhouse effect and related topics came into secondary curriculum during the 1990-ies in many countries. The presentation will discuss some ideas of how to teach him accordingly at secondary education. Ausubel, D. P. 1968: Educational Psychology: A Cognitive View. Holt, Rinehart and Winston Inc.

The alienation theme present in many short stories in Bosnia and Herzegovina also appears in a particularly impressive way in a short story Raggedy Africa by a Slovenian author Mark Švabič, which is clearly related to a short story The Seaside Fairy Tale by Miljenko Jergović from Bosnia and Herzegovina. Extremely interesting are the stories that suggest a crisis of legitimacy of culture and behavior, such as the story of Tito or Curriculum Vitae by a Slovenian writer Maja Novak, or Bankophobia by Ante Zirdum, demonstrating the individual culture of behavior and society in general in a regressive dimension manifested through addiction or phobia from banking institutions.

    The 12th International Symposium on Continuum Models and Discrete Systems (CMDS-12) (http://www.saha.ac.in/cmp/cmds.12/) took place at the Saha Institute of Nuclear Physics in Kolkata from 21-25 February 2011. Previous CMDS symposia were held in Kielce (Poland, 1975), Mont Gabriel (Canada, 1977), Freudenstadt (Federal Republic of Germany, 1979), Stockholm (Sweden, 1981), Nottingham (United Kingdom, 1985), Dijon (France, 1989), Paderborn (Germany, 1992), Varna (Bulgaria, 1995), Istanbul (Turkey, 1998), Shoresh (Israel, 2003) and Paris (France, 2007). The broad interdisciplinary character, limited number of participants (not exceeding 100) and informal and friendly atmosphere of these meetings has made them a well-acknowledged place to make highly fruitful contacts and exchange ideas, methods and results. The purpose of CMDS is to bring together scientists with different backgrounds who work on continuum theories of discrete mechanical and thermodynamical systems in the fields of mathematics, theoretical and applied mechanics, physics, material science, and engineering. The spirit of the CMDS meetings is to stimulate extensive and active interdisciplinary research. The International Scientific Committee members of this conference were: David J Bergman (Chairman CMDS 10), Tel Aviv University, Israel; Bikas K Chakrabarti (Chairman CMDS 12), Saha Institute of Nuclear Physics, India; Alex Hansen, Norwegian University of Science and Technology, Norway; Hans Jürgen Herrmann, Institute for Building Materials, ETH, Switzerland; Esin Inan (Chairman CMDS 9), Istanbul Technical University, Turkey; Dominique Jeulin (Chairman CMDS 11), Ecole des Mines de Paris, France; Frank Juelicher, Max-Planck-Institute for the Physics of Complex Systems, Germany; Hikaru Kawamura, University of Osaka, Japan; Graeme Milton, University of Utah, USA; Natalia Movchan, University of Liverpool, UK; and Ping Sheng, The Hong Kong University of Science and Technology, Hong Kong.

In prayer no. 86 the praise refers not only to the significance of St. Mary as the Mother of God, but to her purely feminine and maternal functions and her role of a participant and witness to the life and passion of Christ. They find their equivalents in Marian and Christological artistic series of the time. One of them is a series of scenes on the wooden door of the church Sankta Maria im Kapitol in Cologne, made ca 1050. The church was rebuilt by abbotess Ida, one of Gertrude’s aunts, who also funded the door. In this church Gertrude’s mother, Richeza, was buried. Gertrude could see the door during her stay in Rhineland in the years 1075-1076. A number o f depictions are included in miniatures in the manuscripts from the Ottonian epoch, e.g. a Scripture-Book of abbotess Hitda of Meschede from ca 1020, with an Annunciation scene. Gertrude knew a different presentation o f this scene from monumental mosaics in Kiev. The maternity o f St. Mary was presented in many different types of the Nativity. An exceptionally extended depiction in the eastern spirit, including a reference to apocryphal texts, is shown in one o f the Codex’ miniatures.

It is a relatively short book, written in a very fluent style, but it deals with all the major problems and achievements of Einstein's works. Starting from special relativity, it continues with general relativity, quantum theories, unified field theory and a brief overview of the actual research related to Einstein's legacy. It is essentially a popular science book with some related exploration in history and philosophy to interpret physical theories. The most important problem discussed by Damour is the nature of time. On this subject, there is a very interesting short paragraph (pp 33--35) dedicated to the reception of the relativity idea by the great writer Marcel Proust and its counterpart within A la Recherche du Temps Perdu. A correct discussion of the implications of a relativistic time should imply the distinction of the different possible interpretations of this concept. Damour seems to conclude that only one interpretation is possible: 'time does not exist', flowing of time is an illusion. One has to know that Einstein's ideas on time were related to Spinoza's perspective of a knowledge sub specie aeternitatis. However, other interpretations are possible and are related to the idea of time as an actuality. Damour speaks about the controversy between Einstein and Bergson, but Bergson is considered as a philosopher who did not understand relativity.

    Full Text Available Over the last 11 years the prevalence of diabetes in Ukraine has increased rapidly – from 1.8 to 2.8%. This especially concerns children and adolescents. The progression and compensation of the diabetes depend on many factors. In today’s medical literature the role of Helicobacter рylori in the development and progression of diabetic gastroparesis is widely discussed. In addition, the issue of the necessity and feasibility of H. Pylori eradication in these patients is also keenly discussed. The results are rather contradictory. The results of infection of H. рylori, the peculiarities of progression, the impact on the compensation of H. рylori in patients with diabetes of I and II type are provided in this article. Materials and methods. The study included 52 patients with diabetes in which the erythematous and erosive gastropathy were found during fibrogastroduodenoscopy. The diagnosis of diabetes was set according to the criteria of the American Diabetes Association, year 2010. The patients were treated at the gastroenterology and endocrinology department of the A. Novak Uzhhorod Regional Clinical Hospital. Glycated hemoglobin (HbA1c was measured in all of the patients. H. рylori was measured by a quick test for determining the Helicobacter pylori antigen in the stool using the test system Cer Test Diotec Sl., Spain. Results and discussion. 65% of the women and 35% of the men were studied. The group with type I diabetes comprised of 76% women and 24% men, andwith type II diabetes – 44% women and 56% men. The age of the patients with type I diabetes – 44.5±3.79 years, type II diabetes - 51±3.86. The study of the patients with type I diabetes has shown the presence of helicobacter infection in 35% of the patients. In patients with type II diabetes the presence of H. рylori antigen in stool was found in 77% of the patients. In patients with type I diabetes infected with H. рylori (first group asthenoneurotic syndrome prevailed in

It strikes one as particularly odd how little writing has been devoted to the first Bjelovar weekly newspaper, Tjednik bjelovarsko-križevački. Our paper is an overview of the facts on the beginning of its publication, the makeup of the editorial board and the editors in chief, the contents, genres, columns, circulation, distribution, popularisation and layout. The range of topics covered, the overall atmosphere and the wide scope of the social life covered by the newspaper shed light on its influence on the development of literacy and the culture of reading, and on its role in the cultural, educational and political life of the town and the region in the late 19th and early 20th century. A special reason for writing this text resides in the fact that in the absence of other source material Tjednik bjelovarsko-križevački is an important tool in the study of the local history. The chief study sources were the complete annual editions of Tjednik stored in the National University Library. Bibliographic sources and material were consulted regarding the development of printing and the publication of periodicals. The theoretical starting points were found in the works of Josip Horvat, Božidar Novak, Srećko Lipovčan, Ivanka Kuić, Ivo Perić, Vjekoslav Maštrović and others. The paper utilises the historic and comparative methods, and the methods of compilation, description, analysis and synthesis. The first regionally distributed weeklies were commonly published by local printers with businesses set up in the district centres. An enormous breakthrough in the development of

    Thibault Damour is a theoretical physicist, and a member of the French Academy of Sciences. This book is the translation, by Eric Novak, of the original French Si Einstein m'etait conte (Le Cherche Midi, 2005). It is neither a book of theoretical physics nor a biography of Einstein. It is not a book of history nor philosophy of science. In Damour's words it was written to encourage the reader to share with Einstein 'those times when he understood some part of the hidden order of the universe'. It is a relatively short book, written in a very fluent style, but it deals with all the major problems and achievements of Einstein's works. Starting from special relativity, it continues with general relativity, quantum theories, unified field theory and a brief overview of the actual research related to Einstein's legacy. It is essentially a popular science book with some related exploration in history and philosophy to interpret physical theories. The most important problem discussed by Damour is the nature of time. On this subject, there is a very interesting short paragraph (pp 33--35) dedicated to the reception of the relativity idea by the great writer Marcel Proust and its counterpart within A la Recherche du Temps Perdu. A correct discussion of the implications of a relativistic time should imply the distinction of the different possible interpretations of this concept. Damour seems to conclude that only one interpretation is possible: 'time does not exist', flowing of time is an illusion. One has to know that Einstein's ideas on time were related to Spinoza's perspective of a knowledge sub specie aeternitatis. However, other interpretations are possible and are related to the idea of time as an actuality. Damour speaks about the controversy between Einstein and Bergson, but Bergson is considered as a philosopher who did not understand relativity. This philosophical problem of relativistic time is indeed related to a historical problem briefly discussed by Damour

    Francel Delgado. Extranjeros, mujeres, familias y esclavos son los principales actores históricos  relacionados con el caso colombiano. Las expulsiones de extranjeros por Roger Pita Pico, la mujer y los negocios en la ciudad de Barranquilla por Tomás Caballero Truyol, el impacto del certificado médico prenupcial de las nuevas familias en Antioquia por Natalia María Gutiérrez Urquijo, y la manumisión de esclavos por compra y gracia en esa región por Karen Mejía Velásquez y Luis Miguel Córdoba Ochoa, constituyen los principales aportes. Ya en el plano político, zona andina central, al suroccidente colombiano y Ecuador, autores como William Alfredo Chapman Quevedo, Ángela Lucía Agudelo González y Alex Silgado Ramos estudian la relación de los impresos y la incidencia de grupos políticos en la opinión pública en la primera mitad del siglo diecinueve; mientras que en el escenario quiteño de finales de mismo siglo, Luis Esteban Vizuete Marcillo estudia las estrategias e iniciativas del clero contra la Revolución Liberal en 1895. Ese papel del Iglesia, en el caso del Obispado de Villarica en Chile, es analizado también según la reconstrucción de nuevos espacios de poder —zonas indígenas chilenas— a partir de la cartografía histórica por Hernán Leonel González Quitulef y Daniel Rodrigo Llancavil. Mientra que en el contexto mexicano, Ramón Goyas Mejía, estudia la desaparición de lo pueblos de indios en la costa sur de la Nueva Galicia durante el periodo colonial. Y, cerrando la Sección Artículos, Gustavo Lorenzana Duran estudia el reparto agrario en el valle del Yaqui (Sonora a partir de un diferendo diplomático entre México y los Estados Unidos entre 1936 y 1938.

Оksana Maksymiuk, Natalia Maksymiuk. Functional and semantic parameters of the refusal communicative act in Ukrainian literary discourse. The article is dedicated to the communicative act. The communicative act is defined as concep- tually and structurally organized exchange of communicative acti- vities of speakers with in the verbal contact, in which the basic meaning is a discourse that relies on a certain situation. So the research of refusal communicative acts becomes urgent because they are inelienable components of everyday speech and they operate on the field of noncooperative verbal interaction and also the analysis of semantical, pragmatical and discussional peculiarities. Semantic and pragmatic aspects of research involves the descrip- tion of refusal communicative acts from the viewpoint of the theory of speech genres and the theory of speech acts. Cognitive and communicative-pragmatic aspects are harmoniously combined and focused in the structure of the «linguistic identity» notion. Having analysed precisely the internal structure of the comm- unicative act we can make the conclusions that refusal acts as polyillocutiv items by its nature show broad functional variability of speaker’s intention. The dominating component of the content or the method of its transfer the illocutive means are combined in acts of assertion and direction of the pragmatic space of interaction. In acts assertion the assertive and expressive strenght (positive sign become crucial, in acts of

Thirdly, Rosario Martí Marco reconstructs "La historiografía literaria alemana"; Jesús García Gabaldón "La evolución de la historiografía literaria eslava" and Natalia Timoshenko completes the historiographical reconstruction with an "Introducción a la historiografía literaria rusa". There is not any monography reconstructing a Roman historiography (Spanish, French, Italian as this is the most comprehensive and less problematic field in regard to availability and is the best known to Western readers.

According to the editor, Aullón de Haro, the idea of action and human sense depends on the concept and knowledge of history. The possibility to overcome the decline of the discipline -and even civilizational- divisions depends on an alive historical self-consciousness. After the fall of structural-formalism, a form of self-consciousness has ended, being now necessary to re-establish a historiographical methodology of ethical, critical and humanistic value, and with this, a philosophical, literary and artistic History: a project capable of assuming a conception of the object as synthesis of idea and form, and where it is universal, not the mere sum of parts. With this contribution, the Research Group Humanism-Europe provides a tool for examining a great humanistic problem that now, for a necessarily common future, demands a proper

The conference site is the new ICT building at chaired by Professor Kalle-Antti Suominen (http://www.congress.utu.fi/cewqo2009, www.congress.utu.fi/cewqo2009). The conference site was the new ICT building at the University of Turku campus area and the Viking Line ferry boat. Turku is the central city of historical Finland established on the mouth of the river Aura in the 13th century. It is the birthplace of Finnish academic life, since the Academy of Turku was established there in 1640. In 2011, Turku will be one of the cultural capitals of Europe. The city has a strong maritime tradition and is shielded from the Baltic sea by a large and beautiful archipelago. The 17th Central European Workshop on Quantum Optics will be held in 2010 in St Andrews, UK. It will be chaired by Professors Ulf Leonhardt and Natalia Korolkova from the School of Physics and Astronomy, University of St Andrews. St Andrews is home to the first university of Scotland, the third-oldest in the English-speaking world, and is the home of golf. It remains a charming, eccentric seaside town that is sufficiently secluded - the ideal place for a stimulating and thought-provoking conference.
