    2008-01-01

    It was with great sadness that we learned that our colleague and friend Mario Weiss passed away on February 11th. A feeling of emptiness overtook us all. Mario was a reassuring reference in the small community of linear accelerator experts, as he continued to come to CERN regularly and discuss accelerator problems with passion for many years after his official retirement. Mario came to CERN in 1960 and in the PS Division worked on beam dynamics of low-energy high-intensity proton beams, soon becoming a world-level expert in the field. He took an active part in the construction of Linac2, where he was responsible for the low-energy beam transport system. In the early 80’s he turned his interest to the Radio Frequency Quadrupole (RFQ), a novel concept for acceleration which allows the problems related with bunching and injecting low-energy beams to be overcomed. After starting a fruitful collaboration with the Los Alamos scientists, ...

  5. Multiple phase transitions in the generalized Curie-Weiss model

    International Nuclear Information System (INIS)

    Eisele, T.; Ellis, R.S.

    1988-01-01

    The generalized Curie-Weiss model is an extension of the classical Curie-Weiss model in which the quadratic interaction function of the mean spin value is replaced by a more general interaction function. It is shown that the generalized Curie-Weiss model can have a sequence of phase transitions at different critical temperatures. Both first-order and second-order phase transitions can occur, and explicit criteria for the two types are given. Three examples of generalized Curie-Weiss models are worked out in detail, including one example with infinitely many phase transitions. A number of results are derived using large-deviation techniques

    2012-08-01

    Full Text Available Abstract Introduction Spontaneous osteonecrosis of the navicular bone in adults is a rare entity, known as Müller-Weiss syndrome. We report here on our experience with six patients with Müller-Weiss syndrome accompanied by flatfoot deformity, but on a literature search found no reports on this phenomenon. Because the natural history and treatment are controversial, an understanding of how to manage this deformity may be helpful for surgeons when choosing the most appropriate operative procedure. Case presentation Six patients (five women, one man; average age, 54 years with flatfoot caused by osteonecrosis of the navicular bone were followed up between January 2005 and December 2008 (mean follow-up period, 23.2 months. Conservative treatment, such as physical therapy, and non-steroidal anti-inflammatory drugs were used, but failed. Physical examinations revealed flattening of the medial arch of the involved foot and mild tenderness at the mid-tarsal joint. Weight-bearing X-rays (anterior-posterior and lateral views, computed tomography, and MRI scans were performed for each case. Talonavicular joint arthrodesis was performed in cases of single talonavicular joint arthritis. Triple arthrodesis was performed in cases of triple joint arthritis to reconstruct the medial arch. Clinical outcomes were assessed using the American Orthopaedic Foot and Ankle Society ankle-hindfoot scale; the scores were 63.0 pre-operatively and 89.8 post-operatively. All patients developed bony fusion. Conclusions The reason for the development of flatfoot in patients with Müller-Weiss syndrome is unknown. Surgical treatment may achieve favorable outcomes in terms of deformity correction, pain relief, and functional restoration. The choice of operative procedure may differ in patients with both flatfoot and posterior tibial tendon dysfunction.

    Initially, the present report outlines the work done by P. Weiss in the molecular field and spontaneous magnetization theory. It then stresses the success of the theory in the interpretation of the magnetic and energetic properties of ferro-magnetic bodies, and indicates recent progress: 'the energetic molecular field, and the corrective molecular field of the equation of state'. In the second part, the author reviews the difficulties encountered by the theory, and shows how they were overcome by the introduction of the notion of the 'local molecular field', thus supplying the key to the properties of anti-ferro and ferri-magnetic bodies. The present level of progress in the interpretation of the magnetic properties of pyrrhotite, which played a major part in the molecular field discoveries, is also discussed in paragraph 4 and appendices. (author) [French] Dans une premiere partie, l'auteur retrace l'historique des travaux de P. Weiss sur la theorie du champ moleculaire et l'aimantation spontanee; il en souligne les succes dans l'interpretation des proprietes magnetiques et energetiques des corps ferro-magnetiques et les perfectionnements ultimes: champ moleculaire energetique et champ moleculaire correctif de l'equation d'etat. Dans une deuxieme partie, apres avoir examine les difficultes auxquelles se heurtait la theorie, l'auteur montre qu'elles ont ete resolues en introduisant la notion de champ moleculaire local et en donnant ainsi la cle des proprietes des corps antiferro-et ferri-magnetiques. II etudie egalement (paragraphe 4 et Appendice) l'etat actuel de l'interpretation des proprietes magnetiques de la pyrrhotine qui a joue un grand role dans l'histoire du champ moleculaire. (auteur)

    1988-01-01

    Edoardo Weiss, the only direct disciple of Freud in Italy, returned to Trieste, his native town, in 1919 after a long period of psychoanalitical studies in Vienna. An enthusiastic acceptance of Freud's ideas in the cultural, mainly Jewish, circles in Trieste was parallel to a sort of distrust of the Fascist ideology. In 1930 Weiss decided to move to Rome where he hoped to be able to found an Italian psychoanalytical movement. The Catholic Church, Fascist Ideology, philosophical Idealism and scientific Positivism were all factors hampering the spread of psychoanalysis in Italy. In 1932 Weiss founded the Italian Psychoanalytical Society in Rome with a very small number of followers. The relations between Weiss' newborn Society and the dictatorship were going to be quite troublesome. Ernst Jones was drastically accused by Weiss of misrepresenting his entrée with Mussolini. Thanks to Weiss' efforts the Italian society was acknowledged by the I.P.A. Finally, mention will be made of Weiss' forced move to America as a result of the racial laws, and of the consequences for the future of Psychoanalysis in Italy.

  18. On the equivalence of dilute antiferromagnets and ferromagnets in random external fields: Curie-Weiss models

    Using a method proposed by van Hemmen the free energy of the Curie-Weiss version of the site-dilute antiferromagnetic Ising model is computed, in the presence of an uniform magnetic field. The solution displays an exact correspondence between this model and the Curie-Weiss version of the Ising model in the presence of a random magnetic field. The phase diagrams are discussed and a tricritical point is shown to exist. (Author) [pt

    Co-doped ZnO and Al, Co co-doped ZnO polycrystalline powders were synthesized by co-precipitation method. The magnetization curves measured at 2 K show no hysteresis neither remanence for all samples. ZnO:Co grown at low temperature has a positive Curie–Weiss temperature Θ, and ZnO:Co grown at high temperature has a negative Θ. But Al-doped ZnO:Co grown at high temperature has a positive Θ. Positive Curie–Weiss temperature Θ was considered to have relation to the presence of shallow donors in the samples. - Highlights: • Co-doped ZnO and Al, Co co-doped ZnO polycrystalline powders were synthesized. • No hysteresis is observed for all samples. • The Curie–Weiss temperature Θ changes its sign by Al doping. • Positive Θ should be related to shallow donors.

    2007-01-01

    Reinhold Mueller has been the one and only historian of medicine in Germany who worked in the field of the Indian history of medicine from the 1920s to the 1960s. He influenced German, American and Indian researchers, but he was nearly forgotten soon after his death. This is the first paper about his life and work to be published. Mueller studied a wide range of topics, the history of Indian gynaecology, of psychiatry, of immunology and of general practice and his subsequent articles were published in the principal contemporary magazines. However, he did not have a perfect understanding of Sanskrit language and writing. Moreover, as he subordinated his research to the premises of National Socialism and of communism, some of his articles have to be seen as part of an Aryan-Germanic race discourse. Yet, these inadequacies and mistakes did not prevent other researchers from maintaining contact with him after 1945. Even when Anglo-American historians of medicine began to study Indian medicine in the 1980s, his publications were re-examined and analysed.

  5. Misjudging frustrations in spin liquids from oversimplified use of Curie-Weiss law

    Absence of a single smoking-gun experiment to identify a quantum spin liquid, has kept their characterisation difficult till date. Featureless dc magnetic susceptibility and large antiferromagnetic frustration are always considered as the essential pointers to these systems. However, we show that the amount of frustration estimated by using generalised Curie-Weiss law on these susceptibility data are prone to errors and thus should be dealt with caution. We measure and analyse susceptibility data of Ba{sub 3}ZnIr{sub 2}O{sub 9}, a spin orbital liquid candidate and Gd{sub 2}O{sub 3}, a 1.5 K antiferromagnet and show the distinguishing features between them. A continuous and significant change in Curie and Weiss constants is seen to take place in Ba{sub 3}ZnIr{sub 2}O{sub 9} and other reported spin liquids with the change in the range of fitting temperatures showing the need of a temperature ‘range-of-fit’ analysis before commenting on the Weiss constants of spin liquids. The variation observed is similar to fluctuations among topological sectors persisting over a range of temperature in spin-ice candidates. On the other hand, even though we find correlations to exist at even 100 times the ordering temperature in Gd{sub 2}O{sub 3}, no such fluctuation is observed which may be used as an additional distinguishing signature of spin liquids over similarly featureless correlated paramagnets. - Highlights: • Curie-Weiss fitting may give erroneous frustration parameters in spin-liquids. • The results depend upon choice of fitting method and temperature range used. • More appropriate method is to use a ʽrange of fit’ analysis. • Can distinguish between spin-liquids and correlated paramagnets.

    Full Text Available The author examines the legacy of two great Christian thinkers, the American Reinhold Niebuhr and the Italian Giorgio La Pira, both very influential during the Cold War. Niebuhr was a Protestant theologian and political adviser to the American establishment. The Mayor of Florence, La Pira, was a prominent Italian statesman and an eminent Catholic thinker. The author analyzes their views on international relations, in particularly on the western policy towards the Soviet Union, the use of nuclear weapons, the war in Vietnam and communism. The legacy of two thinkers is highly topical in front of the ethical dimension of choices needed in international politics today.

    2018-04-01

    This paper proposes a conditional Curie-Weiss model as a model for decision making in a stylized society made up of binary decision makers that face a particular dichotomous choice between two options. Following Brock and Durlauf (Discrete choice with social interaction I: theory, 1955), we set-up both socio-economic and statistical mechanical models for the choice problem. We point out when both the socio-economic and statistical mechanical models give rise to the same self-consistent equilibrium mean choice level(s). Phase diagram of the associated statistical mechanical model and its socio-economic implications are discussed.

    1994-11-01

    We study here the magnetic properties of Y- and Lu- Iron Garnets using the Bethe- Peierls-Weiss method modified to suit complex systems like these Garnets. We consider these Garnets as described by Heisenberg Hamiltonian with two sublattices (a,d) and determine the exchange interaction parameters Jad, Jaa and Jdd by matching the exerimental susceptibility curves. We find Jaa and Jdd to be much smaller than those determined by Néel theory, and consistent with those obtained by the study of spin wave spectra; the spin wave dispersion relation constant obtained using these parameters gives good agreement with the experimental values.

    Although, trauma, foot deformity (pesplanovalgus), systemic diseases such as diabetes mellitus and lupus, drugs (steroids, antineoplastic) and excessive alcohol consumption have all been accused in the etiology of avascular necrosis of the tarsal bones, spontaneous avascular necrosis of the navicular bone, especially in adults, is a rare entity. In this article, we report a 50-year-old female patient with bilateral, spontaneous avascular necrosis of the navicular bone and related severe talonavicular arthrosis. Clinical and radiological findings were concordant with Müller-Weiss disease, which is a rare disease with complex idiopathic foot condition of the adult tarsal navicular bone characterized by progressive navicular fragmentation and talonavicular joint destruction. The patient was successfully treated with two-staged bilateral talonavicular arthrodesis.

  12. Asymptotic densities from the modified Montroll-Weiss equation for coupled CTRWs

    2018-01-01

    We examine the bi-scaling behavior of Lévy walks with nonlinear coupling, where χ, the particle displacement during each step, is coupled to the duration of the step, τ, by χ τβ. An example of such a process is regular Lévy walks, where β = 1. In recent years such processes were shown to be highly useful for analysis of a class of Langevin dynamics, in particular a system of Sisyphus laser-cooled atoms in an optical lattice, where β = 3/2. We discuss the well-known decoupling approximation used to describe the central part of the particles' position distribution, and use the recently introduced infinite-covariant density approach to study the large fluctuations. Since the density of the step displacements is fat-tailed, the last travel event must be treated with care for the latter. This effect requires a modification of the Montroll-Weiss equation, an equation which has proved important for the analysis of many microscopic models.

    The aim of this study was to identify the predictive factors influencing mortality in patients with bleeding Mallory-Weiss syndrome in comparison with peptic ulcer bleeding. Between January 2005 and December 2009, 281 patients with endoscopically confirmed Mallory-Weiss syndrome and 1530 patients with peptic ulcer bleeding were consecutively evaluated. The 30-day mortality and clinical outcome were related to the patients' demographic data, endoscopic, and clinical characteristics. The one-year cumulative incidence for bleeding Mallory-Weiss syndrome was 7.3 cases/100,000 people and for peptic ulcer bleeding 40.4 cases/100,000 people. The age-standardized incidence for both bleeding Mallory-Weiss syndrome and peptic ulcer bleeding remained unchanged during the observational five-year period. The majority of patients with bleeding Mallory-Weiss syndrome were male patients with significant overall comorbidities (ASA class 3-4). Overall 30-day mortality rate was 5.3% for patients with bleeding Mallory-Weiss syndrome and 4.6% for patients with peptic ulcer bleeding (p = 0.578). In both patients with bleeding Mallory-Weiss syndrome and peptic ulcer bleeding, mortality was significantly higher in patients over 65 years of age and those with significant overall comorbidities (ASA class 3-4). The incidence of bleeding Mallory-Weiss syndrome and peptic ulcer bleeding has not changed over a five-year observational period. The overall 30-day mortality was almost equal for both bleeding Mallory-Weiss syndrome and peptic ulcer bleeding and was positively correlated to older age and underlying comorbid illnesses.

    2017-08-01

    In this paper the author sheds light on Vanda Shrenger Weiss, a forgotten pioneer of the international psychoanalytic movement. Vanda Shrenger was born into a large Jewish family in Croatia (1892), and her life was thoroughly intertwined with the great tragedies of European history: the First World War, the anti-Semitic persecution within Eastern Europe, which entailed the decimation of her extended family in Croatia. Finally, the introduction of fascist laws in Italy led to her and her husband - Edoardo Weiss, the founder of the Italian Psychoanalytic Society - seeking refuge in the United States of America. During her time spent in Italy (1919-39), Vanda Shrenger, doctor and paediatrician, dedicated herself to psychoanalysis. She played a crucial part in the reconstruction of the Italian Psychoanalytic Society (SPI), whilst also being a founding member of the Rivista Italiana di Psicoanalisi (Rome, 1932). Vanda was the first woman to be a member of the SPI as well as to present a paper for it.

    We generalize the Wilemski-Fixman-Weiss decoupling approximation to calculate the transient rate of absorption of point particles into multiple sinks of different sizes, shapes, and reactivities. As an application we consider the case involving two spherical sinks. We obtain a Laplace-transform expression for the transient rate that is in excellent agreement with computer simulations. The long-time steady-state rate has a relatively simple expression, which clearly shows the dependence on the diffusion constant of the particles and on the sizes and reactivities of sinks, and its numerical result is in good agreement with the known exact result that is given in terms of recursion relations.

    We study the conditional probabilities of the Curie-Weiss Ising model in vanishing external field under a symmetric independent stochastic spin-flip dynamics and discuss their set of bad configurations (points of discontinuity). We exhibit a complete analysis of the transition between Gibbsian and non-Gibbsian behavior as a function of time, extending the results for the corresponding lattice model, where only partial answers can be obtained. For initial inverse temperature $\\b \\leq 1$, we prove that the time-evolved measure is always Gibbsian. For $1 \\frac{3}{2}$, we observe the new phenomenon of symmetry-breaking of bad configurations: The time-evolved measure loses its Gibbsian character at a sharp transition time, and bad configurations with non-zero spin-average appear. These bad configurations merge into a neutral configuration at a later transition time, while the measure stays non-Gibbs. In our proof we give a detailed analysis of the phase-diagram of a Curie-Weiss random field Ising model with possi...

    In this article, we review how two eminent Viennese system thinkers, Paul A Weiss and Ludwig von Bertalanffy, began to develop their own perspectives toward a system theory of life in the 1920s. Their work is especially rooted in experimental biology as performed at the Biologische Versuchsanstalt, as well as in philosophy, and they converge in basic concepts. We underline the conceptual connections of their thinking, among them the organism as an organized system, hierarchical organization, and primary activity. With their system thinking, both biologists shared a strong desire to overcome what they viewed as a “mechanistic” approach in biology. Their interpretations are relevant to the renaissance of system thinking in biology—“systems biology.” Unless otherwise noted, all translations are our own. PMID:18217527

  1. Large deviations of the finite-time magnetization of the Curie-Weiss random-field Ising model

    Paga, Pierre; Kühn, Reimer

    2017-08-01

    We study the large deviations of the magnetization at some finite time in the Curie-Weiss random field Ising model with parallel updating. While relaxation dynamics in an infinite-time horizon gives rise to unique dynamical trajectories [specified by initial conditions and governed by first-order dynamics of the form mt +1=f (mt) ] , we observe that the introduction of a finite-time horizon and the specification of terminal conditions can generate a host of metastable solutions obeying second-order dynamics. We show that these solutions are governed by a Newtonian-like dynamics in discrete time which permits solutions in terms of both the first-order relaxation ("forward") dynamics and the backward dynamics mt +1=f-1(mt) . Our approach allows us to classify trajectories for a given final magnetization as stable or metastable according to the value of the rate function associated with them. We find that in analogy to the Freidlin-Wentzell description of the stochastic dynamics of escape from metastable states, the dominant trajectories may switch between the two types (forward and backward) of first-order dynamics. Additionally, we show how to compute rate functions when uncertainty in the quenched disorder is introduced.

    We describe the clinical and radiological manifestations of the Jackson-Weiss syndrome (JWS) in a large South Australian kindred. Radiological abnormalities not previously described in the hands include coned epiphyses, distal and middle phalangeal hypoplasia, and carpal bone malsegmentation. New radiological findings in the feet include coned epiphyses, hallux valgus, phalangeal, tarso-navicular and calcaneo-navicular fusions, and uniform absence of metatarsal fusions. Absence of linkage to eight markers along the short arm of chromosome 7 excluded allelian between JWS and Saethre-Chotzen syndrome at 7p21. No linkage was detected to D5S211, excluding allelism to another recently described cephalosyndactyly syndrome mapping to 5qter. 35 refs., 5 figs., 4 tabs.

    Full Text Available Mallory-Weiss syndrome (MWS accounts for 6–14% of all cases of upper gastrointestinal bleeding. Prognosis of patients with MWS is generally good, with a benign course and rare recurrence of bleeding. However, no strict recommendations exist in regard to the mode of action after a failure of primary endoscopic hemostasis. We report a case of an 83-year-old male with MWS and rebleeding after the initial endoscopic treatment with epinephrine and clips. The final endoscopic control of bleeding was achieved by a combined application of clips and a nylon snare in a “tulip-bundle” fashion. The patient had an uneventful postprocedural clinical course and was discharged from the hospital five days later. To the best of our knowledge, this is the first case report showing the “tulip-bundle” technique as a rescue endoscopic bleeding control in the esophagus.

    2005-01-01

    This paper presents the efforts made to study the process of comminution to Weiss domain polarization and phase transition in piezoceramics together with the versatility of low-temperature-cofired ceramics-based devices and components for their ready adoption for typical applications in the area of micro-fluidics. A conceptual micro-fluidic module has been presented and few unit entities necessary for its realization have been described. The purpose of these entities is to position the sensors and actuators by using piezoelectric materials. Investigations are performed to make useful constructions like diaphragms and cantilevers for laying the sensing elements, cavities for burying the electronic chip devices, and channels for fluid transportation. In order to realize these constructions, the basic step involves machining of circular, straight line, rectangular and square-shaped structure in the green ceramic tapes followed by lamination and firing with post-machining in some cases. The diaphragm and cavity includes one or more un-machined layer stacked together with several machined layers with rectangular or square slits. The cantilever is an extension of the diaphragm creation process with inclusion of a post-machining step. The channel essentially consists of a machined green ceramic layer sandwiched between an un-machined and a partially machined layer. The fabrication for all the above constructions has been exemplified and the details have been discussed

    AIM: To systematically review the data on distinctive aspects of peptic ulcer disease (PUD), Dieulafoy’s lesion (DL), and Mallory-Weiss syndrome (MWS) in patients with advanced alcoholic liver disease (aALD), including alcoholic hepatitis or alcoholic cirrhosis. METHODS: Computerized literature search performed via PubMed using the following medical subject heading terms and keywords: “alcoholic liver disease”, “alcoholic hepatitis”,“ alcoholic cirrhosis”, “cirrhosis”, “liver disease”, “upper gastrointestinal bleeding”, “non-variceal upper gastrointestinal bleeding”, “PUD”, ‘‘DL’’, ‘‘Mallory-Weiss tear”, and “MWS’’. RESULTS: While the majority of acute gastrointestinal (GI) bleeding with aALD is related to portal hypertension, about 30%-40% of acute GI bleeding in patients with aALD is unrelated to portal hypertension. Such bleeding constitutes an important complication of aALD because of its frequency, severity, and associated mortality. Patients with cirrhosis have a markedly increased risk of PUD, which further increases with the progression of cirrhosis. Patients with cirrhosis or aALD and peptic ulcer bleeding (PUB) have worse clinical outcomes than other patients with PUB, including uncontrolled bleeding, rebleeding, and mortality. Alcohol consumption, nonsteroidal anti-inflammatory drug use, and portal hypertension may have a pathogenic role in the development of PUD in patients with aALD. Limited data suggest that Helicobacter pylori does not play a significant role in the pathogenesis of PUD in most cirrhotic patients. The frequency of bleeding from DL appears to be increased in patients with aALD. DL may be associated with an especially high mortality in these patients. MWS is strongly associated with heavy alcohol consumption from binge drinking or chronic alcoholism, and is associated with aALD. Patients with aALD have more severe MWS bleeding and are more likely to rebleed when compared to non

    The Weiss Functional Impairment Rating Scale-Parent Form (WFIRS-P) is a 50-item scale that assesses functional impairment on six clinically relevant domains typically affected in attention-deficit/hyperactivity disorder (ADHD). As functional impairment is central to ADHD, the WFIRS-P offers potential as a tool for assessing functional impairment in ADHD. These analyses were designed to examine the overall performance of WFIRS-P in differentiating ADHD and non-ADHD cases using receiver operating characteristics (ROC) analysis. This is the first attempt to empirically determine the level of functional impairment that differentiates ADHD children from normal controls. This observational study comprised 5-19-year-olds with physician-diagnosed ADHD (n = 476) and non-ADHD controls (n = 202). ROC analysis evaluated the ability of WFIRS-P to discriminate between ADHD and non-ADHD, and identified a WFIRS-P cut-off score that optimises correct classification. Data were analysed for the complete sample, for males versus females and for participants in two age groups (5-12 versus 13-19 years). Area under the curve (AUC) was 0.91 (95% confidence interval 0.88-0.93) for the overall WFIRS-P score, suggesting highly accurate classification of ADHD distinct from non-ADHD. Sensitivity (0.83) and specificity (0.85) were maximal for a mean overall WFIRS-P score of 0.65, suggesting that this is an appropriate threshold for differentiation. DeLong's test found no significant differences in AUCs for males versus females or 5-12 versus 13-19 years, suggesting that WFIRS-P is an accurate classifier of ADHD across gender and age. When assessing function, WFIRS-P appears to provide a simple and effective basis for differentiating between individuals with/without ADHD in terms of functional impairment.

    Measurement properties of the Weiss Functional Impairment Rating Scale-Parent Report Form (WFIRS-P), which assesses attention-deficit/hyperactivity disorder (ADHD)-related functional impairment in children/adolescents (6-17 years), were examined. Data from seven randomized, controlled trials were pooled. Analyses were conducted in two random half-samples. WFIRS-P conceptual framework was evaluated using confirmatory factor analyses (CFA). Reliability was estimated using internal consistency (Cronbach's alpha) and test-retest reliability methods. Convergent validity was assessed using correlations between WFIRS-P domain scores and the ADHD-RS-IV and Clinical Global Impression-Severity (CGI-S) scales. Responsiveness was tested by comparing mean changes in WFIRS-P domain scores between responders and non-responders based on clinical criteria. CFA adequately confirmed the item-to-scale relationships defined in the WFIRS-P conceptual framework. Cronbach's alpha coefficient exceeded 0.7 for all domains and test-retest reliability exceeded 0.7 for all but Risky Activities. With few exceptions, WFIRS-P domains correlated significantly (p ADHD-RS-IV Total, Inattention and Hyperactivity-Impulsivity scores and CGI-S at baseline and follow-up in both random half-samples. Mean changes in WFIRS-P domain scores differed significantly between responder and non-responder groups in the expected direction (p < 0.001). Study results support the reliability, validity and responsiveness of the WFIRS-P. Findings were replicated between two random samples, further demonstrating the robustness of results.

    Full Text Available Cet article analyse les idées et l’œuvre de la directrice de l’École des mères, Augusta Moll-Weiss. Dans le contexte du tournant des XIXe-XXe siècles où l’éloge de la ménagère est un thème récurrent des discours moralisateurs émanant des ouvriers ou des bourgeois, Augusta Moll-Weiss met en place un projet de cours ménagers. Son œuvre offre une approche singulière de ce que des activités reconnues comme typiquement féminines peuvent offrir aux femmes. Loin de former uniquement des « fées du logis », les cours professés à l’École des mères donnent aussi aux élèves la possibilité de se préparer à une carrière professionnelle. Augusta Moll-Weiss imagine alors pléthore de débouchés qui placent les activités « du souci des autres » dans la sphère du travail social. Son engagement en faveur de l’enseignement ménager s’accompagne d’une réflexion sur de nouveaux modèles domestiques susceptibles d’accompagner l’entrée des femmes sur le marché du travail. La rationalisation et le partage sexué des tâches domestiques ainsi que la question du temps partiel sont au cœur de son projet. Aux marges de la philanthropie et du féminisme, Augusta Moll-Weiss s’engage donc dans une stratégie de reconnaissance du rôle des femmes dans l’espace civique. Après avoir présenté l’œuvre scolaire de cette femme, cet article s’intéresse à sa vision de la « Ménagère nouvelle » et à son approche du féminisme.This article explores the ideas and works of the Augusta Moll-Weiss, head of the École des mères.

    Objective: To test the reliability and validity of Chinese version of the Weiss Functional Impairment Scale-Parent form (WFIRS-P) in China. Methods: Totally 123 outpatients who met the diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) for attention deficit hyperactivity disorder (ADHD) and 240 normal children were recruited in this study. The parents of the subjects completed the WFIRS-P. At the same time, the parents of 39 outpatients comleted the ADHD Rating Scale-IV (ADHD RS-IV) and Behavior Rating Inventory of Executive Function (BRIEF) and doctors who made diagnosis for these 39 outpatients filled in the Global Assessment Function (GAF) to test the criteria validity. One or two weeks later, the parents of 29 outpatients were required to complete the WFIRS-P again to test the test-retest reliability. Results: The test-retest reliability were 0. 61 - 0. 87 and the Cronbach a coefficients were 0. 70 - 0. 92. Subscale scores of WFIRS-P were significantly correlated with scores of ADHD RS-IV (r = 0. 32 - 0. 50, P < 0. 05), BRIEF (r = 0. 23 -0. 71, P < 0. 05) and GAF (r = - 0. 29 - - 0. 59, P < 0. 05). Lisrel Confirmatory factor analysis showed the 5 -subscale model of BRIEF was reasonable (CFI = 0. 97 for control group, 0. 89 for ADHD group, RMSEA < 0. 08). Compared with control group, the ADHD group got significant higher scores in all subscales of WFIRS-P respectively (Ps < 0. 01) .

    Cheung, Alfred K. C.; Raghu, S.; Mulligan, Michael

    2017-06-01

    Particle-hole symmetry in the lowest Landau level of the two-dimensional electron gas requires the electrical Hall conductivity to equal ±e2/2 h at half filling. We study the consequences of weakly broken particle-hole symmetry for magnetoresistance oscillations about half filling in the presence of an applied periodic one-dimensional electrostatic potential using the Dirac composite fermion theory proposed by Son [Son, Phys. Rev. X 5, 031027 (2015), 10.1103/PhysRevX.5.031027]. At fixed electron density, the oscillation minima are asymmetrically biased towards higher magnetic fields, while at fixed magnetic field the oscillations occur symmetrically as the electron density is varied about half filling. We find an approximate "sum rule" obeyed for all pairs of oscillation minima that can be tested in experiment. The locations of the magnetoresistance oscillation minima for the composite fermion theory of Halperin, Lee, and Read (HLR) and its particle-hole conjugate agree exactly. Within the current experimental resolution, the locations of the oscillation minima produced by the Dirac composite fermion coincide with those of HLR. These results may indicate that all three composite fermion theories describe the same long-wavelength physics.

  11. INTRAVAL Phase 2: Investigations into the influence of the density stratification on groundwater flow by the example of pumping test 'Weisses Moor'

    International Nuclear Information System (INIS)

    Wollrath, J.; Arens, G.

    1992-11-01

    After a short description of the pumping test the determination of the aquifer parameters permeability k, storage coefficient S and aquifer thickness b is described on the basis of the analytical THEIS-solution for the calculation of the drawdown of a well. The numerical computations with the computer codes SUTRA and ROCKFLOW based on this are described. The computations have led to the result that the drawdown values observed in the pumping test can be described with the assumptions based on the THEIS-solution. The computations considering the density stratification do not show significant differences compared to the freshwater computations. The influence of the arrangement of filter areas in the well or the distribution of the pumped water along that filter areas is greater than the influence of the computation as freshwater or salt-water model. However, the difference between the observed density of the pumped water and the computed density is in the range of 20 to 50% depending on the model variant. It can be concluded that the flow conditions for this pumping test cannot be validated with the simple approaches and models used. (orig.) [de

    Full Text Available Background and Purpose: Multi-parametric MRI of the entire spine is technologist-dependent, time consuming, and often limited by inhomogeneous fat suppression. We tested a technique to provide rapid automated total spine MRI screening with improved tissue contrast through optimized fat-water separation.Methods: The entire spine was auto-imaged in two contiguous 35 cm field of view (FOV sagittal stations, utilizing out-of-phase fast gradient echo (FGRE and T1 and/or T2 weighted fast spin echo (FSE IDEAL (Iterative Decomposition of Water and Fat with Echo Asymmetric and Least-squares Estimation sequences. 18 subjects were studied, one twice at 3.0T (pre and post contrast and one at both 1.5 T and 3.0T for a total of 20 spine examinations (8 at 1.5 T and 12 at 3.0T. Images were independently evaluated by two neuroradiologists and run through Automated Spine Survey Iterative Scan Technique (ASSIST analysis software for automated vertebral numbering.Results: In all 20 total spine studies, neuroradiologist and computer ASSIST labeling were concordant. In all cases, IDEAL provided uniform fat and water separation throughout the entire 70 cm FOV imaged. Two subjects demonstrated breast metastases and one had a large presumptive schwannoma. 14 subjects demonstrated degenerative disc disease with associated Modic Type I or II changes at one or more levels. FGRE ASSIST afforded subminute submillimeter in-plane resolution of the entire spine with high contrast between discs and vertebrae at both 1.5 and 3.0T. Marrow signal abnormalities could be particularly well characterized with IDEAL derived images and parametric maps.Conclusion: IDEAL ASSIST is a promising MRI technique affording a rapid automated high resolution, high contrast survey of the entire spine with optimized tissue characterization.

    Directory of Open Access Journals (Sweden)

    Víctor Manuel Conde-Vela

    2017-09-01

    Full Text Available Most species belonging to Namanereis Chamberlin, 1919 live in freshwater and subterranean waters, even in water bodies several meters above sea level. A new species belonging to the stygobiont Namanereis group is described here; it shares the common morphological characters of absence of eyes and pigmentation, bifid jaws, elongation of chaetae and cirri, which have been recently regarded as troglomorphies. Because these features are used in evaluations of phylogenetic affinity in Namanereis, a review of these features was made for all known namanereidins, and it was extended to include species in Namalycastis Hartman, 1959. It is shown that elongation of tentacular and dorsal cirri, or elongation of upper sub-acicular falcigers in pre- or post-acicular fascicles, are not exclusive or restricted to species living in subterranean habitats or to Namanereis, because these features are also present in several Namalycastis species. However, the presence of bifid jaws, and the absence of eyes are exclusively found in namanereidins living in subterranean habitats. A hypothetical evolutionary derivation of bifid jaws is proposed, based upon observations of jaw morphology of several species. These exclusive troglomorphic characters (bifid jaws, eyeless are regarded as convergent features to aphotic environments, and they should be discouraged as indicators of common ancestry. The new species, herein described as Namanereis christopheri sp. n., was collected in a cave 435 m above sea level in Saint Vincent, Caribbean Sea. The species resembles N. cavernicola but it differs because it has shorter tentacular cirri, margin of prostomium entire, rounded neuropodial lobes and broader dorsal cirri throughout body. A key to identify all known Namanereis species is included.

  5. Word-embeddings Italian semantic spaces: A semantic model for psycholinguistic research

    Directory of Open Access Journals (Sweden)

    Marelli Marco

    2017-01-01

    Full Text Available Distributional semantics has been for long a source of successful models in psycholinguistics, permitting to obtain semantic estimates for a large number of words in an automatic and fast way. However, resources in this respect remain scarce or limitedly accessible for languages different from English. The present paper describes WEISS (Word-Embeddings Italian Semantic Space, a distributional semantic model based on Italian. WEISS includes models of semantic representations that are trained adopting state-of-the-art word-embeddings methods, applying neural networks to induce distributed representations for lexical meanings. The resource is evaluated against two test sets, demonstrating that WEISS obtains a better performance with respect to a baseline encoding word associations. Moreover, an extensive qualitative analysis of the WEISS output provides examples of the model potentialities in capturing several semantic phenomena. Two variants of WEISS are released and made easily accessible via web through the SNAUT graphic interface.

    Full Text Available Este artigo visa mostrar a contribuição que Reinhold oferece para o Idealismo Alemão, período filosófico subsequente a Kant quando, determinado a encontrar o ponto de partida do qual derive os conhecimentos teórico e moral, não hesita em examinar cuidadosamente todas as filosofias que imediatamente surgem após a dele e, muitas vezes, até se rende a elas, considerando-as mais apropriadas que a sua própria para o alcance daquilo que buscava: um primeiro princípio que vincule o que em Kant estava separado. Para tanto, Reinhold parte do método transcendental kantiano, e, assim, tenta também, numa só tacada, escapar daquilo que Jacobi chamou de subjetivismo absoluto, referindo-se ao método kantiano.

  9. Reminders of duty: A Kantian theory of blame

    OpenAIRE

    Scholten, M.

    2016-01-01

    This dissertation develops a Kantian quality of will account of moral blameworthiness. Part I starts with a discussion of the Reinhold/Sidgwick Objection. According to this objection, anyone who accepts the Kantian conception of autonomy is forced to draw the absurd conclusion that no one is ever morally blameworthy for anything. I show that this objection depends on the implicit premise that freedom is a necessary condition for moral blameworthiness. While rejecting the standard Kantian repl...

  13. Behavioural measures of child's eating temperament and their link with BMI.

    Science.gov (United States)

    2017-03-01

    Rothbart's model of temperament, defined as individual differences in reactivity and self-regulation, has a strong heuristic value with applications in a wide variety of children's outcomes. Our objective was to test Rothbart's model applied to children's food behaviours and BMI outcome through behavioural measures. Our hypotheses, according to Rothbart's model, were as follows: (i) self-regulation in eating modulates appetite reactivity; (ii) appetite reactivity increases the risk of excess BMI, whereas self-regulation in eating limits this risk. One hundred and four children aged between 7 and 12 years completed four behavioural tasks to assess scores for two components of appetite reactivity (i.e. appetite arousal and appetite persistence) and two components of self-regulation in eating (i.e. self-regulation in eating without hunger and self-regulation in eating speed). Their heights and weights were measured in order to calculate their BMI-for-age. T-tests and regression analysis were used to verify our hypotheses. None of the scores of self-regulation in eating was directly associated with BMI but we observed a significant impact of self-regulation in eating without hunger on appetite arousal (p-value = 0.04), together with a modest but significant association between appetite persistence and BMI (p-value = 0.02). We can thus conclude that our behavioural measures could be used for the determination of the child's eating temperament. Further studies are needed to investigate how to use these measures to improve the treatment of overweight in children. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The accelerating frequency of the 600 MeV Synchro-Cyclotron (SC) was modulated by the varying capacity of a rotating condenser ("Rotco", the most delicate component of the SC). A 1/5-scale model, dating from the design-period of the SC, was used to study improvements to the SC RF-system, and also the acceleration of ions, first Helium and, at the time of this picture, Carbon. In the middle of the picture is the case containing the Dees. To the left, at the wide end of the cone, a rotco. Reinhold Hohbach is busy with measurements.

Reinhold Niebuhr and the World Council of Churches challenged Cold War liberalism from within. As they did, they anticipated and even applauded the anti-liberalism of early Cold War conservatives. While exploring intellectual precursors of the New Left, this essay forefronts one forgotten byproduct of the political realignments following World War II: The transgressive politics of “conservative socialism.” Furthermore, this work contributes to growing awareness of ecumenical Christian impact within American life.

O presente estudo teve por objetivo revisar de forma sistemática estudos empíricos, publicados de 2001 a 2006, sobre o tema temperamento e sua relação com o desenvolvimento da criança. Foram selecionados 50 estudos empíricos indexados nas bases de dados PsycINFO, MEDLINE e LILACS por meio de levantamento bibliográfico sistematizado.Verificou-se que a abordagem teórico-conceitual mais adotada pelos estudos foi a abordagem psicobiológica de Rothbart. O temperamento foi avaliado predominantemente por meio de questionários respondidos pelas mães. Os resultados dos estudos indicaram que crianças com o temperamento caracterizado por alto nível de humor negativo, medo, timidez e raiva encontram-se, do ponto de vista do desenvolvimento, suscetíveis de apresentar problemas de desenvolvimento. O temperamento com alto nível de controle com esforço, que indica a capacidade de superar tendências comportamentais e motivacionais dirigidas pelo afeto e reprogramar seu comportamento em situações de conflito de interesses associa-se a resultados desenvolvimentais positivos.El temperamento es una variable de carácter personal que interactúa con las variables ambientales y por lo tanto puede tener una influencia en el desarrollo infantil.

    The rare ant mimicking sac spider genus Aetius was erected by O. Pickard-Cambridge in 1896 based on an unspecified number of female specimen(s) collected from Sri Lanka. The type species of the genus, A. decollatus O. Pickard-Cambridge, 1896, has been redescribed twice based on the holotype (Majumder & Tikader 1991; Deeleman-Reinhold 2001). Reimoser (1934) recorded the genus for the first time from India, who collected a male specimen from Mudumalai Tiger Reserve in Tamil Nadu State of southern India. This specimen was identified as A. decollatus, but it was never formally described and was later recognised to be a penultimate male (Dankittipakul & Singtripop 2013). Deeleman-Reinhold (2001) described the second representative of the genus, A. nocturnus, based on a single female specimen from Borneo, 105 years after the establishment of the genus. Dankittipakul & Singtripop (2013) described the male of A. nocturnus, thereby revealing the male genitalia of the genus, but the type species was still known only from the female sex.

  3. Coupled Thermo-Mechanical and Photo-Chemical Degradation Mechanisms that determine the Reliability and Operational Lifetimes for CPV Technologies

    Energy Technology Data Exchange (ETDEWEB)

    2017-04-30

    This project sought to identify and characterize the coupled intrinsic photo-chemo-mechanical degradation mechanisms that determine the reliability and operational lifetimes for CPV technologies. Over a three year period, we have completed a highly successful program which has developed quantitative metrologies and detailed physics-based degradation models, providing new insight into the fundamental reliability physics necessary for improving materials, creating accelerated testing protocols, and producing more accurate lifetime predictions. The tasks for the program were separated into two focus areas shown in the figure below. Focus Area 1, led by Reinhold Dauskardt and Warren Cai with a primary collaboration with David Miller of NREL, studied the degradation mechanisms present in encapsulant materials. Focus Area 2, led by Reinhold Dauskardt and Ryan Brock with a primary collaboration with James Ermer and Peter Hebert of Spectrolab, studied stress development and degradation within internal CPV device interfaces. Each focus area was productive, leading to several publications, including findings on the degradation of silicone encapsulant under terrestrial UV, a model for photodegradation of silicone encapsulant adhesion, quantification and process tuning of antireflective layers on CPV, and discovery of a thermal cycling degradation mechanism present in metal gridline structures.

    Iron clusters have been prepared within zeolite holes by reduction of zeolites containing ferrous ions. The diameter of these particles must therefore be smaller that 13 A. They are superparamagnetic and their Moessbauer spectra show no HFS, even at 4K. The temperature dependence of the magnetic susceptibility of the unreduced zeolites obeys a Curie-Weiss law with p/sub eff/ = 4.45 ..mu..B and THETA = 105K. The Weiss curves of the reduced samples lie distinctly below those of the bulk material.

    Full Text Available Das spätromantische Interesse für Ortsüberlieferungen, angeregt von den “Deutschen Sagen” (1816–1818 der Brüder Grimm, blühte im Baltikum in den 1830er und 1840er Jahren auf und gipfelte – im estnischen Sprachgebiet – in der zweisprachigen Ausgabe des estnischen Nationalepos “Kalevipoeg” / “Kalew’s Sohn” (1857–1861, dem Friedrich Reinhold Kreutzwald seine Endgestalt gab, aber das von mehreren Sammlern und Bearbeitern geprägt wurde. Literarische Bearbeitungen von Volkssagen fanden schnell ihren Weg in Zeitungen und Zeitschriften, in Gedichtbände und Anthologien – oft in modischer Balladenform, die dem mythisch-romantischen Inhalt der Volkssage am besten zu entsprechen schien. Die Blütezeit der Sagendichtung im Baltikum sind die 1840er Jahre, als vor allem in der Zeitschrift „Das Inland“ mehrere dichterischen Bearbeitungen estnischer und lettischer Volkssagen erschienen (von Heinrich Blindner, Otto Dreistern, Eduard Pabst, Minna von Mädler, Theodor Rutenberg, Robert Falck, P. Otto u. a. 1845 erschien hier das nach einer Sage von Friedrich Robert Faehlmann verfasste Gedicht „Koit und Hämarik / Morgenroth und Abendroth“ von Minna von Mädler – fünf Jahre vor der Fassung von Friedrich Reinhold Kreutzwalds estnischsprachiger Ballade „Koit ja Hämarik“. Zwischen 1831 und 1836 verfasste Friedrich Reinhold Kreutzwald seine deutschsprachigen Balladen, von denen „Die Belagerung von Bewerin im Jahre 1207“ 1846 im „Inland“ gedruckt wurde. Das Jahr 1846 kann als „Balladenjahr“ der Zeitschrift bezeichnet werden. Die eigentliche Domäne der deutschbaltischen (lyro-epischen Dichtung ist die historische Ballade, die fußend auf baltischen Chroniken und Familiengeschichten zumeist von Ruinen alter Schlösser und den sie einst bewohnenden historischen Personen und deren Heldentaten berichtet. Doch schon im Jahre 1847 kann man im Inland die Kritik gegenüber diesem Balladenboom vernehmen, u.a. mit dem

  16. The role of mechanical boundary conditions in the soft mode dynamics of PbTiO3.

    Science.gov (United States)

    McCash, Kevin; Mani, B K; Chang, C-M; Ponomareva, I

    2014-10-29

    The role of different mechanical boundary conditions in the soft mode dynamics of ferroelectric PbTiO3 is systematically investigated using first-principles-based simulations and analytical model. The change in the soft mode dynamics due to hydrostatic pressure, uniaxial and biaxial stresses and biaxial strains is studied in a wide temperature range. Our computations predict: (i) the existence of Curie-Weiss laws that relate the soft mode frequency to the stress or strain; (ii) a non-trivial temperature evolution of the associated Curie-Weiss constants; (iii) a qualitative difference between the soft mode response to stresses/strains and hydrostatic pressure. The latter finding implies that the Curie-Weiss pressure law commonly used for residual stress estimation may not apply for the cases of uniaxial and biaxial stresses and strains. On the other hand, our systematic study offers a way to eliminate this difficulty through the establishment of Curie-Weiss stress and strain laws. Implications of our predictions for some available experimental data are discussed.

    Although other researchers had previously observed the random motion of pollen grains suspended in water through a microscope, Robert Brown's name is associated with this behaviour based on observations he made in 1828. It was not until Einstein's work in the early 1900s however, that the origin of this irregular motion was established to be the result of collisions with molecules which were so small as to be invisible in a light microscope (Einstein A 1965 Investigations on the Theory of the Brownian Movement ed R Furth (New York: Dover) (transl. Cowper A D) (5 papers)). Jean Perrin in 1908 (Perrin J 1923 Atoms (New York: Van Nostrand-Reinhold) (transl. Hammick D)) was able, through a series of painstaking experiments, to establish the validity of Einstein's equation. We describe here the details of a junior level undergraduate physics laboratory experiment where students used a microscope, a video camera and video capture software to verify Einstein's famous calculation of 1905.

    2008-10-01

    The search for a possible variation of fundamental physical constants isnewsworthy more than ever. A multitude of methods were developed. So far theonly seemingly significant indication of a cosmological variation existsfor the proton-to-electron massratio as stated by Reinhold et al. [1]. The measuredindication of variation is based on the combined analysis of H2 absorptionsystems in the spectra of Q0405-443 and Q0347-383 at zabs=2.595 and zabs=3.025, respectively. The high resolution data of the latteris reanalyzed in this work to examine the influence of different fittingprocedures and further potential nonconformities. This analysis cannotreproduce the significance achieved by the previous works.

    The present work looks into the microstructural modification in electron irradiated Bombyx mori P31 silk fibers. The irradiation process was performed in air at room temperature using 8 MeV electron accelerator at different doses: 0, 25, 50 and 100 kGy. Irradiation of polymer is used to cross-link or degrade the desired component or to fix the polymer morphology. The changes in microstructural parameters in these natural polymer fibers have been computed using wide angle X-ray scattering (WAXS) data and employing line profile analysis (LPA) using Fourier transform technique of Warren. Exponential, Lognormal and Reinhold functions for the column length distributions have been used for the determination of crystal size, lattice strain and enthalpy parameters.

  19. Indulging anxiety: human enhancement from a Protestant perspective.

    Science.gov (United States)

    Hanson, Mark J

    1999-08-01

    At the heart of any ethics of human enhancement must be some normative assumptions about human nature. The purpose of this essay is to draw on themes from a Protestant theological anthropology to provide a basis for understanding and evaluating the tension between maintaining our humanity and enhancing it. Drawing primarily on the work of theologian Reinhold Niebuhr, I interpret enhancement as proceeding from the anxiety that characterizes human experience at the juncture of freedom and finiteness. Religious and moral dimensions of human sinfulness are considered in relation to cultural values that motivate human enhancement generally. I employ these dimensions in a series of benchmarks to suggest a background of theological, anthropological, and moral considerations against which enhancement is not to be condemmed but rather critically evaluated.

  20. Theoretical model for thin ferroelectric films and the multilayer structures based on them

    International Nuclear Information System (INIS)

    Starkov, A. S.; Pakhomov, O. V.; Starkov, I. A.

    2013-01-01

    A modified Weiss mean-field theory is used to study the dependence of the properties of a thin ferroelectric film on its thickness. The possibility of introducing gradient terms into the thermodynamic potential is analyzed using the calculus of variations. An integral equation is introduced to generalize the well-known Langevin equation to the case of the boundaries of a ferroelectric.

    A modified Weiss mean-field theory is used to study the dependence of the properties of a thin ferroelectric film on its thickness. The possibility of introducing gradient terms into the thermodynamic potential is analyzed using the calculus of variations. An integral equation is introduced to generalize the well-known Langevin equation to the case of the boundaries of a ferroelectric.

    MHI studies the method of the spatially dependent resonance cross sections so as to predict the power distribution in a fuel pellet accurately. For this purpose, the multiband method and the Stoker/Weiss method were implemented to the 2 dimensional transport code PHOENIX-P, and the methods were validated by comparing them with MVP code. Although the appropriate reference was not obtain from the deterministic codes on the resonance cross section study, now the Monte Carlo code MVP result is available and useful as reference. It is shown here how MVP is used to develop the multiband method and the Stoker/Weiss method, and how effective the result of MVP is on the study of the resonance cross sections. (author)

    Magnetic susceptibility of 11 glass spherules from the Apollo 14 lunar fines have been measured from room temperature to 4 K. Data taken at room temperature, 77 K, and 4.2 K, show that the soft saturation magnetization was temperature independent. In the temperature range 300 to 77 K the temperature-dependent component of the magnetic susceptibility obeys the Curie law. Susceptibility measurements on these same specimens and in addition 14 similar spherules from the Apollo 11 and 12 mission show a Curie-Weiss relation at temperatures less than 77 K with a Weiss temperature of 3-7 degrees in contrast to 2-3 degrees found for tektites and synthetic glasses of tektite composition. A proposed model and a theoretical expression closely predict the variation of the susceptibility of the glass spherules with temperature.

    The degree to which parent sensitivity and infant temperament distinguish attachment classification was examined. Multilevel modeling was used to assess the effect of parent sensitivity and infant temperament on infant-mother and infant-father attachment. Data were collected from mothers, fathers, and their infants (N = 135) when the infant was 3-, 5-, 7-, 12-, and 14-months old. Temperament was measured using the Infant Behavior Questionnaire-Revised (Gartstein & Rothbart, 2003); parent sensitivity was coded during the Still Face Paradigm (Tronick, Als, Adamson, Wise, & Brazelton, 1978); attachment was coded using the Strange Situation (Ainsworth, Blehar, Waters, & Wall, 1978). Results indicate that mothers and fathers were less sensitive with insecure-avoidant infants. Whereas only one difference was found for infant-mother attachment groups and temperament, five significant differences emerged for infant-father attachment groups, with the majority involving insecure-ambivalent attachment. Infants classified as ambivalent with fathers were higher in perceptual sensitivity and cuddliness and these infants also showed a greater increase in low-intensity pleasure over time compared with other infants. Results indicate the importance of both parent sensitivity and infant temperament, though operating in somewhat different ways, in the development of the infant-mother and infant-father attachment relationship.

    Negative emotionality is considered to be the core of the difficult temperament concept (J. E. Bates, 1989; R. L. Shiner, 1998). In this correlational study, the authors examined whether the relations between children's negative emotionality and problematic behavior (internalizing and externalizing) were partially mediated by parenting style (authoritative and authoritarian) in a community sample of 196 3-year-old children and their mothers. The authors assessed maternal perception of child negative emotionality using the Children's Behavior Questionnaire (M. K. Rothbart, S. A. Ahadi, K. L. Hershey, & P. Fisher, 2001) and assessed problematic child behavior by means of maternal report using the Child Behavior Checklist (T. M. Achenbach, 1992). The results showed that the relations between child negative emotionality and internalizing and externalizing behaviors were partially mediated by mothers' authoritative parenting style. Moreover, when the authors used confirmatory factor analysis to decontaminate possible overlap in item content between measures assessing temperament and problematic behavior, the association between negative emotionality and internalizing behavior was fully mediated by authoritative parenting.

    This study examined the direct and indirect pathways from maternal effortful control to 2 aspects of children's self-regulation-executive functioning and behavioral regulation-via maternal emotional support. Two hundred seventy-eight children and their primary caregivers (96% mothers) participated in laboratory visits when children were 4 and 5 years, and teachers reported on children's behavior at kindergarten. At the 4-year assessment, maternal effortful control was measured using the Adult Temperament Questionnaire (Evans & Rothbart, 2007) and maternal emotional support was observed during a semistructured mother-child problem-solving task. At the 5-year assessment, children's executive functioning was measured using laboratory tasks designed to assess updating/working memory, inhibitory control, and cognitive flexibility, whereas behavioral regulation was assessed via teacher-report questionnaires on children's attention control, discipline and persistence, and work habits. Results from structural equation modeling indicated that, after controlling for child gender and minority status, and maternal education, maternal effortful control was indirectly associated with both child executive functioning and behavioral regulation through maternal emotional support. Maternal effortful control had a direct association with children's teacher-reported behavioral regulation but not observed executive functioning. These findings suggest that maternal effortful control may be a key contributing factor to the development of children's self-regulatory competencies through its impact on maternal emotional support.

    The Temperament in Middle Childhood Questionnaire (TMCQ; Simonds & Rothbart, 2004) is a widely used parent-report measure of temperament. However, neither its lower- nor higher-order structures have been tested via a bottom-up, empirically based approach. We conducted higher- and lower-order exploratory factor analyses (EFAs) of the TMCQ in a large (N = 654) sample of 9-year-olds. Item-level EFAs identified 92 items as suitable (i.e., with loadings ≥.40) for constructing lower-order factors, only half of which resembled a TMCQ scale posited by the measure’s authors. Higher-order EFAs of the lower-order factors showed that a three-factor structure (Impulsivity/Negative Affectivity, Negative Affectivity, and Openness/Assertiveness) was the only admissible solution. Overall, many TMCQ items did not load well onto a lower-order factor. In addition, only three factors, which did not show a clear resemblance to Rothbart’s four-factor model of temperament in middle childhood, were needed to account for the higher-order structure of the TMCQ.

    Dropout of infants in looking time studies sometimes occurs at high rates, raising concerns that the representativeness of the final sample might be reduced in comparison to the originally obtained sample. The current study investigated which infant characteristics play a role in dropout. Infants were presented with a preferential looking task at 6 and 9 months of age. At 9 months of age, an additional habituation task and a subsequent novelty preference task were conducted. In addition, temperament was assessed via the Infant Behavior Questionnaire - Revised (IBQ-R, Gartstein & Rothbart, 2003), and cognitive developmental status was assessed via the Cognitive Scale of the Bayley Scale of Infant and Toddler Development (BSID-III, Bayley, 2006). Dropout was positively related to the IBQ-R temperament scales Distress to Limitations and Approach, and negatively related to the scales Falling Reactivity and Cuddliness. The representativeness of the final sample regarding situation-specific temperament dimensions is affected by dropout. Dropout was not related to cognitive developmental status as measured via the BSID-III, habituation speed and novelty preference. Dropout at 6 months of age was associated with dropout at 9 months of age. We concluded that in looking time studies, the representativeness of the final sample regarding performance-relevant temperament dimensions or cognitive developmental status is not affected by dropout.

    Subdisciplines within psychology frequently examine self-regulation from different frameworks despite conceptually similar definitions of constructs. In the current study, similarities and differences between effortful control, based on the psychobiological model of temperament (Rothbart, Derryberry, & Posner, 1994), and executive functioning are examined and empirically tested in three studies (n = 509). Structural equation modeling indicated that effortful control and executive functioning are strongly associated and overlapping constructs (Study 1). Additionally, results indicated that effortful control is related to the executive function of updating/monitoring information in working memory, but not inhibition (Studies 2 and 3). Study 3 also demonstrates that better updating/monitoring information in working memory and better effortful control were uniquely linked to lower dispositional negative affect, whereas the executive function of low/poor inhibition was uniquely associated with an increased tendency to express negative affect. Furthermore, dispositional negative affect mediated the links between effortful control and, separately, the executive function of updating/monitoring information in working memory and the tendency to express negative affect. The theoretical implications of these findings are discussed, and a potential framework for guiding future work directed at integrating and differentiating aspects of self-regulation is suggested.

  12. Emotional and attentional predictors of self-regulation in early childhood

    Full Text Available The development of self-regulation in early childhood is related to development of emotional regulation and attention, in particular executive attention (Feldman, 2009; Posner & Rothbart, 1998. As the ability to self-regulate is crucial in life (Casey et al., 2011, it is important to reveal early predictors of self-regulation. The aim of the paper is to present the results of longitudinal studies on the relationships between the functioning of attention, regulation of emotion and later self-regulatory abilities. 310 children were assessed at three time points. At 12 months of age emotional regulation in situation of frustration and attention regulation were assessed. At 18 and 24 months behavioral-emotional regulation in the Snack Delay Task was measured. Additionally parents assessed executive attention using The Early Childhood Behavior Questionnaire when children were 26 months old. Structural equation modelling revealed two different paths to development of self-regulatory abilities at 18 months: emotional (reactive system and emotionalattentional and only one emotional-attentional path at 24 months. The early ability to focus attention and later executive attention functioning revealed to be important predictors of self-regulatory abilities both at 18 and 24 months of age.

    The history of the temperament concept begins in ancient Greece. The humoral theory remained influential over the centuries. At the beginning of the 20 th century, both Wilhelm Wundt and his pupil Emil Kraepelin formulated new aspects. Wundt described two dimensions: "speed of variability of emotions" and "intensity of emotions". Kraepelin observed four fundamental states (depressive, manic, irritable and cyclothymic), which he linked to manic-depressive illness. Since then different lines of temperament research have evolved: (1) psychiatric-psychopathological theories (e. g. Ewald, Kretschmer and Sheldon), which tend to see temperament as a dilution of full-blown affective disorders; (2) neurobiological theories (e. g. Pavlov, Eysenck and Gray), which understand temperament as determined by underlying neurobiological processes - especially levels of arousal; and (3) developmental theories (e. g. Chess & Thomas, Rothbart and Kagan), which derived their temperament concept from early childhood observations. Recent theories (e. g. those of Cloninger or Akiskal) combine different aspects. After reviewing the historical temperament concepts we present underlying factors which are linked to affective disorders (such as emotional reactivity, cyclicity or trait affectivity). Finally, we illustrate the importance of temperament concepts for research in affective disorders.

    Previous literature suggests that attention processes such as sustained attention would constitute a developmental foundation for the self-regulatory functions executive functioning and effortful control (e.g., Garon, Bryson, & Smith, 2008; Rothbart, Derryberry, & Posner, 1994). Our main aim was to test this hypothesis by studying whether sustained attention at age 1 year can predict individual differences in self-regulatory functions at age 2 years. Longitudinal data from 66 infants and their parents were included in the study. Sustained attention was assessed during free play at age 1 year; executive functioning, measured using an eye-tracking version of the A-not-B task, and effortful control, measured using parental ratings, were assessed at both age 1 and age 2 years. The results did support a longitudinal prediction of individual differences in 2-year-olds' self-regulatory functions as a function of sustained attention at age 1 year. We also found significant improvement in both executive functioning and effortful control over time, and the two self-regulatory constructs were related in toddlerhood but not in infancy. The study helps increase our understanding of the early development of self-regulatory functions necessary for identifying developmental risks and, in the future, for developing new interventions.

    The authors derive the mean-field approximation from the information-theoretic principle of minimum relative entropy instead of by minimizing Peierls's inequality for the Weiss free energy of statistical physics theory. They show that information theory leads to the statistical mechanics procedure. As an example, they consider a problem in binary image restoration. They find that mean-field annealing compares favorably with the stochastic approach

    The magnetic susceptibility of rare-earth (Y and Lu) iron garnets is studied using a modified Bethe-Peierls-Weiss (BPW) approximation. The modifications enable us to incorporate the three exchange parameters Jad, Jaa and Jdd necessary to describe the systems. We get excellent fits to the experimental susceptibilities from which we determined the J-values. These also give excellent agreement with the spin wave dispersion relation constant D.

    Full Text Available Em 1918, no hospital militar de Pasewalk, o psiquiatra professor Edmund Forster trata, por meio da hipnose, o cabo Adolf Hitler de uma "neurose de guerra" (cegueira histérica. Em 1933, Hitler assume o poder sobre a Alemanha nazista. Pouco tempo depois, Forster entra em contato com um grupo de escritores que viviam em exílio em Paris e passa sigilosamente a eles os seus conhecimentos sobre o caso. O escritor Ernst Weiss, também médico, usa essas informações de Forster para escrever o seu romance A Testemunha Ocular (Der Augenzeuge, que é publicado somente em 1963. O professor Forster comete suicídio em 1933, depois de sofrer uma campanha de denúncias difamantes. Weiss também se suicida em 1940, quando as tropas alemãs invadem Paris. Várias outras pessoas relacionadas ao boletim médico sobre Hitler são assassinadas pela Gestapo.In 1918, in a military reserve hospital located in the small Pomeranian town of Pasewalk, the neuropsychiatrist Prof. Edmund Forster treated Adolf Hitler, an Austrian caporal suffering from a war neurosis (hysterical blindness, using suggestive techniques. Soon after the Hitler’s ascension to the power in the Nazi Germany, in 1933, Dr. Forster met with a group of exiled writers living in Paris and secretly gave them the information about the case. The writer Ernst Weiss, that was also a physician, latter used this information in order to produce his roman "The Eye Witness", which would be published only in 1963. In 1933, Prof. Forster committed suicide in strange circunstances after successive defamatory statements against him. Also Weiss committed suicide in 1940, when German troops invaded Paris. The Gestapo also murdered several other persons involved in the Hitler’s medical chart.

  16. Lagrangian statistics and flow topology in forced two-dimensional turbulence.

    Science.gov (United States)

    Kadoch, B; Del-Castillo-Negrete, D; Bos, W J T; Schneider, K

    2011-03-01

    A study of the relationship between Lagrangian statistics and flow topology in fluid turbulence is presented. The topology is characterized using the Weiss criterion, which provides a conceptually simple tool to partition the flow into topologically different regions: elliptic (vortex dominated), hyperbolic (deformation dominated), and intermediate (turbulent background). The flow corresponds to forced two-dimensional Navier-Stokes turbulence in doubly periodic and circular bounded domains, the latter with no-slip boundary conditions. In the double periodic domain, the probability density function (pdf) of the Weiss field exhibits a negative skewness consistent with the fact that in periodic domains the flow is dominated by coherent vortex structures. On the other hand, in the circular domain, the elliptic and hyperbolic regions seem to be statistically similar. We follow a Lagrangian approach and obtain the statistics by tracking large ensembles of passively advected tracers. The pdfs of residence time in the topologically different regions are computed introducing the Lagrangian Weiss field, i.e., the Weiss field computed along the particles' trajectories. In elliptic and hyperbolic regions, the pdfs of the residence time have self-similar algebraic decaying tails. In contrast, in the intermediate regions the pdf has exponential decaying tails. The conditional pdfs (with respect to the flow topology) of the Lagrangian velocity exhibit Gaussian-like behavior in the periodic and in the bounded domains. In contrast to the freely decaying turbulence case, the conditional pdfs of the Lagrangian acceleration in forced turbulence show a comparable level of intermittency in both the periodic and the bounded domains. The conditional pdfs of the Lagrangian curvature are characterized, in all cases, by self-similar power-law behavior with a decay exponent of order -2.

    International Nuclear Information System (INIS)

    Lueken, H.; Deussen, M.; Jansen, M.; Hesse, W.; Schnick, W.

    1987-01-01

    The magnetic susceptibilities of KO 3 , RbO 3 and CsO 3 have been determined between 3.6 and 250 K. Above 50 K Curie-Weiss behaviour is observed. Magnetic moments of 1.74 μ B (KO 3 , CsO 3 ) and 1.80 μ B (RbO 3 ) calculated from the Curie-Weiss straight lines correspond with spin-only moments expected for isolated O 3 - species with one unpaired electron. The Weiss constants Θ are -34 K (KO 3 ), -23 K (RbO 3 ) and -10 K (CsO 3 ). The low temperature behaviour of KO 3 and RbO 3 (broad maxima in susceptibility at 20 and 17 K, respectively, and minima at 6 K) is typical of systems which show with decreasing temperature low-dimensional antiferromagnetic and three-dimensional magnetic ordering. Inspecting the intermolecular distances between oxygen atoms the pathways of exchange interactions are discussed. (author)

  20. Delocalized and localized states of eg electrons in half-doped manganites.

    Science.gov (United States)

    Winkler, E L; Tovar, M; Causa, M T

    2013-07-24

    We have studied the magnetic behaviour of half-doped manganite Y0.5Ca0.5MnO3 in an extended range of temperatures by means of magnetic susceptibility, χ(T), and electron spin resonance (ESR) experiments. At high temperature the system crystallizes in an orthorhombic structure. The resistivity value, ρ ≃ 0.05 Ω cm at 500 K, indicates a metallic behaviour, while the Curie-Weiss dependence of χ(T) and the thermal evolution of the ESR parameters are very well described by a model that considers a system conformed by localized Mn(4+) cores, [Formula: see text], and itinerant, eg, electrons. The strong coupling between t2g and eg electrons results in an enhanced Curie constant and an FM Curie-Weiss temperature that overcomes the AFM interactions between the [Formula: see text] cores. A transition to a more distorted phase is observed at T ≈ 500 K and signatures of localization of the eg electrons appear in the χ(T) behaviour below 300 K. A new Curie-Weiss regime is observed, where the Curie-constant value is consistent with dimer formation. Based on mean-field calculations, the dimer formation is predicted as a function of the interaction strength between the t2g and eg electrons.

  1. Inversion of Flow Depth and Speed from Tsunami Deposits using TsuSedMod

    Science.gov (United States)

    Spiske, M.; Weiss, R.; Roskosch, J.; Bahlburg, H.

    2008-12-01

    The global evolution of a tsunami wave train can be expressed by the sum of local effects along a tsunami- wave beam. The near-shore evolution of tsunami is very complex as the waves interact with the sea-bottom sediments. Filtered through offshore and onshore erosion and deposition, this evolution is recorded in the coastal area by topographical changes, local erosion and tsunami deposits. Recordable sedimentary on-site features include grain-size distributions and horizontal thickness trends. Immediately after an event, indicators of flow depth and run up extent, such as water marks on buildings and vegetation, debris and plastic bags caught in trees and swash lines, can be measured in the field. A direct measurement of the overland flow velocity is usually not possible. However, regarding recent tsunami events, videos of surveillance cameras or witness accounts helped to estimate the characteristics of overland flow. For historical and paleotsunami events such information is not directly available. Jaffe & Gelfenbaum (2007) developed an inversion model (TsuSedMod) to estimate flow depth and speed based upon the grain-size distribution and the thickness of onshore tsunami sediments. This model assumes a steady distribution of sediment in the water column, for which the appication of the Rouse equation is possible. Further simplifications, especially concerning the turbulence structure, are based on the mixing- length theory by Prandtl, the standard approximation in physical sedimentology. We calculated flow depths for sediments left behind by the 2004 Sumatra-Tsunami in India and Kenya (Weiss & Bahlburg, 2006; Bahlburg & Weiss, 2007) and by the 2006 Java-Tsunami on Java (Piepenbreier et al., 2007), using the model of Jaffe and Gelfenbaum (2007). Estimated flow depth were compared with measured data to extend the validation procedure. This extension is needed to gain confidence and understanding before the next step is taken to compute the near

    2009-01-01

    The present work looks into the microstructural modification in Bombyx mori silk fibers, induced by electron irradiation. The irradiation process was performed in air at room temperature by use of 8 MeV electron accelerators at different doses: 0, 25, 50, 75 and 100 kGy respectively. Irradiation of polymer can be used to crosslink or degrade the desired component or to fixate the polymer morphology. The changes in microstructural parameters in these natural polymer fibers have been studied using wide angle X-ray scattering (WAXS) method. The crystal imperfection parameters such as crystallite size , lattice strain (g in %) and enthalpy (a * ) have been determined by line profile analysis (LPA) using Fourier method of Warren. Exponential, Lognormal and Reinhold functions for the column length distributions have been used for the determination of these parameters. The goodness of the fit and the consistency of these results suggest that the exponential distribution gives much better results, even though lognormal distribution has been widely used to estimate the similar stacking faults in metal oxide compounds.

    In the context of social and intellectual developments and the changing role of German universities in the first half of the nineteenth century, which led to the local institutionalization of the discipline of psychology at German universities, the structure and content of textbooks of psychology are discussed. Textbooks in the first half of the nineteenth century had a pedagogical function in training teachers, in socializing students into the field, and in providing students and readers with knowledge about the subject matter, methodology, and topics of psychology. The textbooks, representative of influence, philosophical-psychological orientations, and different decades in the first half of the nineteenth century, are reconstructed with regard to the definition of psychology, the ways of studying the soul, and how to conceptually organize the field. The textbooks by Herbart, Beneke, and Waitz, which were written within a natural-scientific programmatic vision for psychology, are contrasted with the traditional philosophically intended textbooks of Reinhold, Mussmann, George, and Schilling. Fischhaber's textbook for Gymnasien is summarized. Issues regarding the continuity of psychology are discussed, and discontinuous developments in the history of German psychology are identified.

The mission of this manuscript is to demonstrate a multi-method approach toward de novo glycan characterization and quantitation, including minor species at or approaching the 0.1% benchmark. Recently, unexpected isomers of the Man(5)GlcNAc(2) (M(5)) were reported (Prien JM, Ashline DJ, Lapadula AJ, Zhang H, Reinhold VN. 2009. The high mannose glycans from bovine ribonuclease B isomer characterization by ion trap mass spectrometry (MS). J Am Soc Mass Spectrom. 20:539-556). In the current study, quantitative analysis of these isomers found in commercial M(5) standard demonstrated that they are in low abundance (2-aminobenzoic acid to detect and chromatographically resolve multiple M(5) isomers in bovine ribonuclease B. With this multi-method approach, we have the capabilities to comprehensively characterize a biotherapeutic's glycan array in a de novo manner, including structural isomers at >/=0.1% of the total chromatographic peak area.

    Full Text Available The 13 th World Congress on Medical and Health Informatics (Medinfo was held in 2010 between 12 and 15 September in Cape Town, South Africa. This triennial international gathering is the official conference of the International Medical Informatics Association (IMIA and brings together leading health informatics leaders, scientists, clinicians, researchers, vendors, developers and government and health care planners from around the globe. The conference attracted 905 submissions and resulted in a program that included 260 oral presentations, 349 posters presentations and 21 scientific demonstrations representing contributions from 58 countries. The Medinfo program covered all aspects of health informatics from traditional areas, such as hospital information systems, patient registries, nursing informatics, data integration, standards, interoperability issues and decision support, to innovative topics, such as translational bioinformatics, text mining, intelligent data analysis, emerging technologies, quality, social networking, workflow and organizational issues. The outgoing President of the IMIA, Professor Reinhold Haux, presented on health informatics challenges into the future, reinforcing that today and in the future, health care has to be considered as part of a continuous and coordinated life-time journey and not just as episodes of disease. Medical informatics has a key role to play in this paradigm shift. The new IMIA President, Professor Antoine Geissbuhler, was announced at the closing ceremony. The next Medinfo congress will take place in Copenhagen, Denmark, in September 2013.

  9. Numerical Evaluation of Storm Surge Indices for Public Advisory Purposes

    After the devastating hurricane season of 2005, shortcomings with the Saffir-Simpson Hurricane Scale's (SSHS) ability to characterize a tropical cyclones potential to generate storm surge became widely apparent. As a result, several alternative surge indices were proposed to replace the SSHS, including Powell and Reinhold's Integrated Kinetic Energy (IKE) factor, Kantha's Hurricane Surge Index (HSI), and Irish and Resio's Surge Scale (SS). Of the previous, the IKE factor is the only surge index to-date that truly captures a tropical cyclones integrated intensity, size, and wind field distribution. However, since the IKE factor was proposed in 2007, an accurate assessment of this surge index has not been performed. This study provides the first quantitative evaluation of the IKEs ability to serve as a predictor of a tropical cyclones potential surge impacts as compared to other alternative surge indices. Using the tightly coupled ADvanced CIRCulation and Simulating WAves Nearshore models, the surge and wave responses of Hurricane Ike (2008) and 78 synthetic tropical cyclones were evaluated against the SSHS, IKE, HSI and SS. Results along the upper TX coast of the Gulf of Mexico demonstrate that the HSI performs best in capturing the peak surge response of a tropical cyclone, while the IKE accounting for winds greater than tropical storm intensity (IKETS) provides the most accurate estimate of a tropical cyclones regional surge impacts. These results demonstrate that the appropriate selection of a surge index ultimately depends on what information is of interest to be conveyed to the public and/or scientific community.

    Full Text Available Debemos al empeño del Dr. Juan Carlos Solórzano el que la Editorial de la Universidad de Costa Rica haya efectuado la edición íntegra de Viaje a Centroamérica, del connotado escritor alemán decimonónico Wilhem Marr, con un estudio preliminar con la magnífica traducción filológica efectuada por Irene Reinhold, y numerosas ilustraciones de la época. Se constituye así esta obra en un merecido homenaje a un pensador sagaz, una brillante conciencia crítica, un relator amenísimo, que para la comunidad hispanohablante ha permanecido en el anonimato por más de cien años. Continúa, además, la antiquísima tradición de la narrativa de viajes, que se remonta en Occidente a raíces de vieja prosapia, desde Pausanias y Herodoto, a los textos bíblicos, por mencionar solo algunos. Desde entonces, la literatura de viajes quedó asociada a la aventura de la expansión occidental, siguiendo lo que Ottmar Ette llama “los caminos del deseo”.

  11. Infant joint attention, neural networks and social cognition.

    Mundy, Peter; Jarrold, William

    2010-01-01

    Neural network models of attention can provide a unifying approach to the study of human cognitive and emotional development (Posner & Rothbart, 2007). In this paper we argue that a neural network approach to the infant development of joint attention can inform our understanding of the nature of human social learning, symbolic thought process and social cognition. At its most basic, joint attention involves the capacity to coordinate one's own visual attention with that of another person. We propose that joint attention development involves increments in the capacity to engage in simultaneous or parallel processing of information about one's own attention and the attention of other people. Infant practice with joint attention is both a consequence and an organizer of the development of a distributed and integrated brain network involving frontal and parietal cortical systems. This executive distributed network first serves to regulate the capacity of infants to respond to and direct the overt behavior of other people in order to share experience with others through the social coordination of visual attention. In this paper we describe this parallel and distributed neural network model of joint attention development and discuss two hypotheses that stem from this model. One is that activation of this distributed network during coordinated attention enhances the depth of information processing and encoding beginning in the first year of life. We also propose that with development, joint attention becomes internalized as the capacity to socially coordinate mental attention to internal representations. As this occurs the executive joint attention network makes vital contributions to the development of human symbolic thinking and social cognition. Copyright © 2010 Elsevier Ltd. All rights reserved.

  12. Modelling the effect of temperament on BMI through appetite reactivity and self-regulation in eating: a Structural Equation Modelling approach in young adolescents.

    Appetitive traits and general temperament traits have both been correlated with adiposity and obesity in children. However, very few studies have tested structural models to identify the links between temperament, appetitive traits and adiposity in children. A validated structural model would help suggesting mechanisms to explain the impact of temperament on body mass index (BMI). In this study, we used Rothbart's heuristic definition of temperament as a starting point to define four appetitive traits, including two appetite reactivity dimensions (Appetite Arousal and Appetite Persistence) and two dimensions of self-regulation in eating (Self-regulation In Eating Without Hunger and Self-regulation in Eating Speed). We conducted a cross-sectional study in young adolescents to validate a structural model including these four appetitive traits, Effortful Control (a general temperament trait) and adiposity. A questionnaire assessing the four appetitive trait dimensions and Effortful Control was completed by adolescents from 10 to 14 years old (n=475), and their BMI-for-age was calculated (n=441). In total, 74% of the study participants were normal weight, 26% were overweight and 8% were obese. We then used structural equation modelling to test the structural model. We identified a well-fitting structural model (Comparative Fit Index=0.91; Root Mean Square Error of Approximation=0.04) that supports the hypothesis that Effortful Control impacts both dimensions of self-regulation in eating, which in turn are linked with both appetite reactivity dimensions. Moreover, Appetite Persistence is the only appetitive trait that was significantly related to adiposity (B=0.12; Pappetite reactivity and self-regulation in eating). Results suggest that young adolescents who exhibit high appetite reactivity but a low level of self-regulation in eating are at higher risk for excess adiposity.

  13. Perceptual Sensitivity and Response to Strong Stimuli Are Related

    Full Text Available To shed new light on the long-standing debate about the (independence of sensitivity to weak stimuli and overreactivity to strong stimuli, we examined the relation between these tendencies within the neurobehavioral framework of the Predictive and Reactive Control Systems (PARCS theory (Tops et al., 2010, 2014. Whereas previous studies only considered overreactivity in terms of the individual tendency to experience unpleasant affect (punishment reactivity resulting from strong sensory stimulation, we also took the individual tendency to experience pleasant affect (reward reactivity resulting from strong sensory stimulation into account. According to PARCS theory, these temperamental tendencies overlap in terms of high reactivity toward stimulation, but oppose each other in terms of the response orientation (approach or avoid. PARCS theory predicts that both types of reactivity to strong stimuli relate to sensitivity to weak stimuli, but that these relationships are suppressed due to the opposing relationship between reward and punishment reactivity. We measured punishment and reward reactivity to strong stimuli and sensitivity to weak stimuli using scales from the Adult Temperament Questionnaire (Evans and Rothbart, 2007. Sensitivity was also measured more objectively using the masked auditory threshold. We found that sensitivity to weak stimuli (both self-reported and objectively assessed was positively associated with self-reported punishment and reward reactivity to strong stimuli, but only when these reactivity measures were controlled for each other, implicating a mutual suppression effect. These results are in line with PARCS theory and suggest that sensitivity to weak stimuli and overreactivity are dependent, but this dependency is likely to be obscured if punishment and reward reactivity are not both taken into account.

    Cross-cultural differences in temperament were evaluated for Ethiopian (N=109) and U.S. (N=109) samples of infants. We anticipated that the Sidama version of the Infant Behavior Questionnaire-Revised (IBQ-R; Gartstein & Rothbart, 2003) developed for use in Ethiopia would demonstrate satisfactory psychometric properties, and hypothesized significant cross-cultural differences in levels of fine-grained temperament characteristics. Interactions between culture, infant age, and sex were also considered. Internal consistency was satisfactory for 13 of the 14 IBQ-R scales (with a somewhat low estimate observed for Duration of Orienting), and an examination of the structure indicated patterns similar to those observed in the US, and elsewhere. Differences between Ethiopia and the US were noted for Activity Level, Distress to Limitations, Fear, Smiling/Laughter, Falling Reactivity, Cuddliness/Affiliation, Sadness, Approach, and Vocal Reactivity. Parents of infants in the US reported higher levels of attributes associated with Surgency/Positive Affectivity (Activity, Smiling/Laughter, Approach Vocal Reactivity), whereas Ethiopian infants' scores were higher for Distress to Limitations and Fear, linked with the over-arching temperament factor of Negative Emotionality; however, US infants received higher ratings on Sadness, also associated with this factor. Higher Falling Reactivity, a regulation-related attribute, was reported for Ethiopian infants, with US babies receiving higher Cuddliness/Affiliation scores. Significant culture*age interactions were observed for Activity and Fear, along with a significant culture*age*sex interaction for Distress to Limitations. Copyright © 2016 Elsevier Inc.

    In this reply to the comment on ‘Oxygen vacancy-induced magnetic moment in edge-sharing CuO2 chains of {{{Li}}}2{{{CuO}}}2-δ ’ (2017 New Journal of Physics 19 023206), we have clarified several key questions and conflicting results regarding the size of the intra-chain nearest neighbor coupling J 1 and the sign of the Weiss temperature Θ defined in the Curie–Weiss law of χ(T) = χ ◦ + C/(T ‑ Θ). Additional data analysis is conducted to verify the validity of the Curie–Weiss law fitting protocol, including the negative sign and size of Θ based on the high-temperature linear temperature dependence of 1/χ(T) for T > J 1 and \\tfrac{g{μ }B{SH}}{{k}BT}\\ll 1. The consistency between the magnetic antiferromagnetic (AF) ground state below T N and the negative sign of Θ in the high-temperature paramagnetic (PM) state is explained via the reduction of thermal fluctuation for a temperature-independent local field due to magnetic interaction of quantum nature. A magnetic dipole–dipole (MDD)-type interaction among FM chains is identified and proposed to be necessary for the 3D AF magnetic ground state formation, i.e., the Heisenberg model of an exchange-type interaction alone is not sufficient to fully describe the quasi-1D spin chain system of {{{Li}}}2{{{CuO}}}2. Several typical quasi-1D spin chain compounds, including {{{Li}}}2{{{CuO}}}2,{{{CuAs}}}2{{{O}}}4,{{{Sr}}}3{{{Fe}}}2{{{O}}}5, and CuGeO3, are compared to show why different magnetic ground states are achieved from the chemical bond perspective.

    Introduction: A consequence of diagnosis of adrenocortical carcinoma (ACC) is introduction of pharmacological therapy, precise monitoring of the patients and in some cases re-operation. The aim of the study is to analyse morphology of adrenocortical tumours as regards their malignancy by use of criteria proposed by Weiss. Material and methods: 110 adrenocortical tumours in 107 patients were analysed (M 27.1%, F 72.9%; age 32 to 77 years, mean 55.2 ± 9.7). Conn syndrome was diagnosed in 16 patients (14.9%), Cushing syndrome in 12 (11.2%), and virilisation in 3 (2.8%). In 76 patients (71.0%) biochemical tests did not reveal hormonal hyperactivity of the tumour. Results: In routine histopathological examination ACC was diagnosed in 6 tumours (5.4%), adrenocortical adenoma (ACA) in 92 (83.6%) and adrenocortical hyperplasia in 12 (10.9%). Nuclear grade III or IV was observed in 8 tumours (7.3%), mitotic rate > 5/50 high power fields in 6 (5.4%), atypical mitoses in 5 (4.5%), clear cells constituting < 25% of the tumour in 10 (9.1%), diffuse architecture in 8 (7.3%), necrosis in 16 (14.5%), veins infiltration in 4 (3.6%), sinusoids infiltration in 7 (6.3%), and tumour capsule infiltration in 5 (4.5%). Among ACC tumours 4 - 9 features of malignancy were present, among ACA - 0 - 3 features. Statistical analysis revealed correlation between number of criteria proposed by Weiss and maximal tumour size (p < 0.05). Conclusion: The structure and cell arrangement in adrenocortical adenoma are heterogeneous. Application of criteria proposed by Weiss in histopathological examination of adrenocortical tumours can be useful in differentiating adrenocortical adenoma from carcinoma. (author)

  17. The Paramagnetism of Dissolved Mn in {alpha} and {beta} Brasses

    Energy Technology Data Exchange (ETDEWEB)

    Myers, H P; Westin, R

    1962-12-15

    Paramagnetic susceptibility measurements have been made on {alpha} and {beta} brasses containing {approx} 1 w/o Mn. The susceptibility varied with temperature according to the Curie Weiss law and the Curie constant and thereby the Bohr magneton number per Mn atom were determined. Interpreted in terms of valency, Mn monovalent in copper has a valency in {alpha} brass which decreases progressively with zinc content attaining the value 0.58 at the limiting of composition. Mn in {beta} brass exhibits a valency 0.8. These results are not in keeping with previous values for the valency of manganese as determined from phase boundary relationships and electron to atom ratios.

    A three-dimensional (3D) cobalt phosphate: Co 5(OH 2) 4(HPO 4) 2(PO 4) 2 ( 1), has been synthesized by hydrothermal reaction and characterized by single-crystal X-ray diffraction, thermogravimetric analysis, and magnetic techniques. The title compound is a template free cobalt phosphate. Compound 1 exhibits a complex net architecture based on edge- and corner-sharing of CoO 6 and PO 4 polyhedra. The magnetic susceptibility measurements indicated that the title compound obeys Curie-Weiss behavior down to a temperature of 17 K at which an antiferromagnetic phase transition occurs.

    2000-01-01

    Some magnetic properties of a Diluted Antiferromagnetic System (DAFS) are studied. The model of the two sub-networks for antiferromagnetism is used and a Heisenberg Hamiltonian type is proposed, where the square operators are expressed in terms of boson operators with the approach of spin waves. The behavior of the diluted system's fundamental state depends basically on the competition effect between the anisotropy field and the Weiss molecular field. The approach used allows the diluted system to be worked for strong anisotropies as well as when these are very weak

    CERN Document Server

    This volume shows how collective magnetic excitations determine most of  the magnetic properties of itinerant electron magnets. Previous theories were mainly restricted to the Curie-Weiss law temperature dependence of magnetic susceptibilities. Based on the spin amplitude conservation idea including the zero-point fluctuation amplitude, this book shows that the entire temperature and magnetic field dependence of magnetization curves, even in the ground state, is determined by the effect of spin fluctuations. It also shows that the theoretical consequences are largely in agreement with many experimental observations. The readers will therefore gain a new comprehensive perspective of their unified understanding of itinerant electron magnetism.

    2012-01-01

    An r-Spin Riemann surface is a Riemann surface equipped with a choice of rth root of the (co)tangent bundle. We give a careful construction of the moduli space (orbifold) of r-Spin Riemann surfaces, and explain how to establish a Madsen–Weiss theorem for it. This allows us to prove the “Mumford...... conjecture” for these moduli spaces, but more interestingly allows us to compute their algebraic Picard groups (for g≥10, or g≥9 in the 2-Spin case). We give a complete description of these Picard groups, in terms of explicitly constructed line bundles....

    The magnetic properties of metamaterials based on an opal matrix with transition-metal (iron, nickel, cobalt) particles have been studied. Magnetization curves and magnetic hysteresis loops have been measured and the dependences of real and imaginary parts of magnetization have been determined using the dynamic ac susceptibility measuring procedure. Structural studies of metamaterials have been performed. The saturation magnetization and coercive force of the studied metamaterials have been found to depend weakly on the temperature. The temperature dependence of magnetic susceptibility at a temperature above 30 K can be described adequately by Curie-Weiss law and, at lower temperature, deviates from the law.

This allows us to replace the molecular field by an equivalent energy barrier that the paramagnetic moment of an atom has to cross to contribute to χ. The variation of χ with U, or T as well, shows a maximum when there is no magnetic order. The asymptotic character of the Curie-Weiss law appears in close connection with that of the Dulong and Petit law. (orig.)

    In this work we present magnetic susceptibility results for Cr-x at.% Nb alloys (x = 0.2, 0.6, 0.7, 1.4, and 2.0), showing that a local short-range order spin-density wave (L-SDW) appears at a characteristic temperature (T loc ) above the Neel temperature. The evidence for L-SDW is based on a Curie-Weiss-like behaviour, which is suppressed when large magnetic fields are applied or for alloys with Nb concentration above x = 2.0 at.%

    Full Text Available Em 1918, em um hospital militar da reserva situado na pequena cidade pomerânia de Pasewalk, o neuropsiquiatra Prof. Edmund Forster tratou de um cabo austríaco chamado Adolf Hitler, que apresentava uma neurose de guerra (cegueira histérica, utilizando-se de técnicas terapêuticas sugestivas. Logo após a ascensão de Hitler ao poder na Alemanha nazista, em 1933, o Prof. Forster reuniu-se com um grupo de escritores alemães exilados em Paris e secretamente passou a eles informações sobre o caso. O escritor Ernst Weiss, também médico, mais tarde utilizou tais informações para escrever seu romance A Testemunha Ocular, que, porém, só seria publicado em 1963. Em circunstâncias estranhas, o Prof. Forster cometeu suicídio após uma campanha difamatória sistemática articulada pelos nazistas em 1933. Weiss também cometeu suicídio em 1940, quando as tropas alemãs invadiram Paris. A Gestapo também assassinou diversas outras pessoas envolvidas no prontuário médico de Hitler.In 1918, in a military reserve hospital located in the small pomeranian town of Pasewalk, the neuropsychiatrist Prof. Edmund Forster treated an Austrian caporal called Adolf Hitler, suffering from a war neurosis (hysterical blindness, by means of suggestive techniques.

  1. Nature of the magnetic susceptibility of dysprosium. Paramagnetic susceptibility of dysprosium - yttrium alloys

    International Nuclear Information System (INIS)

    Demidov, V.G.; Levitin, R.Z.; Chistyakov, O.D.

    1976-01-01

    The paramagnetic susceptibility of single crystals of dysprosium-yttirum alloys is measured in the basal plane and along the hexagonal axis. It is shown that the susceptibility of the alloys obeys the Curie-Weiss law, the effective magnetic moments allong the different directions being the same and the paramagnetic Curie temperatures being different. The difference between the paramagnetic Curie temperatures in the basal plane and along the hexagonal axis is independent of the dysprosium concentration in the alloy. As a comparison with the theoretical models of magnetic anisotropy shows, this is an indication that the magnetic anisotropy of dysprosium - yttrium alloys is of a single-ion nature

  5. Magnetic nanoparticles: reactive oxygen species generation and potential therapeutic applications

    Science.gov (United States)

    Mai, Trang; Hilt, J. Zach

    2017-07-01

    Magnetic nanoparticles have been demonstrated to produce reactive oxygen species (ROS), which play a major role in various cellular pathways, via Fenton and Haber-Weiss reaction. ROS act as a double-edged sword inside the body. At normal conditions, the generation of ROS is in balance with their elimination by scavenger systems, and they can promote cell proliferation as well as differentiation. However, at an increased level, they can cause damages to protein, lead to cellular apoptosis, and contribute to many diseases including cancer. Many recent studies proposed a variety of strategies to either suppress toxicity of ROS generation or exploit the elevated ROS levels for cancer therapy.

    Full Text Available Spindle cell hemangioendothelioma (SCH was originally described by Weiss and Enzinger (1986 as a low-grade angiosarcoma resembling both cavernous hemangioma and Kaposi's sarcoma. Recent studies suggest that SCH is a benign neoplasm or reactive lesion accompanying a congenital or acquired vascular malformation. Most SCHs present as one or more nodules affecting the dermis or subcutis of the distal extremities. Few reports describe SCH of the head and neck region; even fewer note intramuscular SCH. Here, we describe a case of SCH involving the temporal muscle mimicking soft tissue sarcoma, who had a successful surgical treatment with a coronal approach and zygomatic osteotomy.

    In the framework of a high energy formulation of relativistic quantum scattering a model is presented which describes the scattering functions and polarization of irregular absorbing particles, whose dimensions are greater than the incident wavelength. More precisely in the forward direction an amplitude parametrization of eikonal type is defined which generalizes the usual diffraction theory, and in the backward direction a reflective model is used including a shadow function. The model predictions are in good agreement with the scattering measurements off irregular compact and fluffy particles performed by Zerull, Giese and Weiss (1977)

    2018-05-01

    In this paper we introduce two measure theoretical notions of conditional entropy for finite measurable covers conditioned to a finite measurable partition and prove that they are equal. Using this we state a local variational principle with respect to the notion of conditional entropy defined by Misiurewicz (1976 Stud. Math. 55 176–200) for the case of open covers. This in particular extends the work done in Romagnoli (2003 Ergod. Theor. Dynam. Syst. 23 1601–10), Glasner and Weiss (2006 Handbook of Dynamical Systems vol 1B (Amsterdam: Elsevier)) and Huang et al (2006 Ergod. Theor. Dynam. Syst. 26 219–45).

    Morris Cohen is mainly remembered as a philosopher of history and law, a friend of jurists (Oliver Wendell Holmes, Felix Frankfurter), and a teacher of more prominent philosophers (e.g., Ernest Nagel, Paul Weiss, Morton White). But his unique position as a student of the work of Russell and Peirce led him to make a distinctive contribution to the debate over realism in in the 1910s. Largely ignored and completely uncited, his early papers formulated what would later be called "objective relativism," influencing the later work of Columbia naturalism, hence American philosophy, from the 1940s to the 1960s.

    We have investigated the pressure dependences of magnetization and the Hall coefficient in the ferromagnetic vanadium oxide NaV 6O 11 up to 1.2 GPa. Structural transitions (hexagonal-hexagonal-orthorhombic) occur at TH = 245 K and TL = 35 K at ambient pressure. Meanwhile, the susceptibility obeys the Curie-Weiss law X = C/( T - θ) with antiferromagnetic correlation of θ TH, with ferromagnetic correlation of θ TH. The spontaneous magnetization appears below Tc = 64.2 K. With increasing pressure, Tc and magnetization M( T TH increases. The sign of the Hall coefficient changes continuously (negative-positive-negative) at around T ≈ 170 K and 75 K.

    Magnetization, electrical resistivity, specific-heat and thermal-expansion measurements have been made on Gd-Y-Lu single crystals. Low isofield magnetization data for the a-axis sample of Gd 75 Y/sub 17.5/ Lu/sub 7.5/ exhibit two different Curie-Weiss regimes, which suggests double ferromagnetism. Electrical resistivity, specific-heat, and thermal-expansion data show two anomalies at the transition temperatures. The anomaly at 231.5 K shows a lambda-type second-order phase transition and the anomaly at 223 K shows a sharp spike first-order phase transition

  2. Electronic and magnetic properties of quasi-skutterudite PrCo2Ga8 compound

    Ogunbunmi, Michael O.; Sondezi, Buyisiwe M.; Nair, Harikrishnan S.; Strydom, André M.

    2018-05-01

    PrCo2Ga8 is an orthorhombic quasi-skutterudite type compound which crystallizes in the CaCo2Al8 structure type, with space group Pbam (No. 55). The Pr3+ ion has a site symmetry of Cs which predicts a crystal electric field (CEF) level splitting into 9 singlets for J = 4. However, a phase transition at Tm = 1.28 K is observed in electrical resistivity and specific heat results and is reported in this paper. The electrical resistivity shows an upturn below Tm due to the superzone-gap formation. This transition is tuneable in fields and is suppressed to lower temperatures with applied magnetic fields. The electronic specific heat Cp(T) / T increases below Tm and reaches a value of 7.37 J/(mol K2) at 0.4 K. The Sommerfeld coefficient, γ extracted from the low temperature analysis of C4f(T) / T is 637 mJ/(mol K2) indicating a possible mass enhancement of the quasiparticles. The calculated entropy value of 3.05 J/(mol K) is recovered around Tm exhibiting almost 53% of Rln2, where R is the universal gas constant. Magnetic susceptibility results obeys the Curie-Weiss law for data above 100 K with an estimated effective magnetic moment, μeff = 3.37 μB/Pr and Weiss temperature, θp = -124 K.

    2018-05-01

    Iridates have recently attracted growing interest because of their potential for realizing various interesting phases like interaction driven Mott-type insulator and magnetically driven Slater-type. In this paper, we present the magnetic and electrical transport properties of polycrystalline Sr2IrO4 synthesized by solid state reaction route. We find a ferromagnetic transition at 240 K. The Curie-Weiss law behavior hold good above the magnetic transition temperature TMag = 240 K with a small effective paramagnetic magnetic moment μeff = 0.25 µB/f.u. and a Curie-Weiss temperature, θCW = +100 K. Zero field cooled (ZFC) magnetization shows a gradual dcrease below 150 K, while same for field cooled (FC) below 50 K. Interestingly, below temperatures, ⁓ 10 K, a sharp increase in ZFC and FC magnetization can be seen. A temperature dependent resistivity reveals insulating behavior followed by power law mechanism. The sintering of sample in air leads to the very low value of resistivity is likely related to Sr or oxygen vacancies.

    Ferromagnetic-phase transition in spinel-type CuCr 2 Te 4 has been clearly observed. CuCr 2 Te 4 is a telluride-spinel with the lattice constant a=11.134A, which has been synthesized successfully. The heat capacity exhibits a sharp peak due to the ferromagnetic-phase transition with the Curie temperature T C =326K. This value of T C corresponds exactly to that of the negative peak of dM/dT in low field of 1.0Oe. The magnetic susceptibility shows the Curie-Weiss behavior between 380 and 650K with the effective magnetic moment μ eff =4.14μ B /Cr-ion and the Weiss constant θ=+357K. The low temperature magnetization indicates the spin-wave excitations, where the existence of first term of Bloch T 3/2 law and the next T 5/2 term are verified experimentally. This spin-wave excitation is detected up to approximately 250K which is a fairly high temperature

  5. Mobilizing technology for developing countries

    Energy Technology Data Exchange (ETDEWEB)

    Weiss, C Jr

    1979-10-01

    Mr. Weiss says that the 15 years since the UN Conference on Science, Technology, and Development in Geneva have taught us that what seem at first to be technological obstacles to development frequently turn out on closer examination to have been policy failures; that introduction of technologies into developing countries must be accompanied by institutional and policy changes if the technologies are to benefit the countries. He points out that choice of alternative technology for a developing country should depend on careful overall assessment of local techno-economic, geographical, ecological, and social factors, as well as the desired balance between growth and equity. Such a technology assessment, a key element in the choice of appropriate (i.e., locally suitable) technology for particular investment projects, should be built into procedures for project preparation and appraisal in governments and development assistance agencies. Turning to technologists, Mr. Weiss says they face a double challenge: (1) to recognize potential for new efforts to harness science and technology for the benefit of the developing countries; and (2) by understanding the social, institutional, and economic framework into which an innovation is to operate, to ease its application and diffusion, and thus speed and increase its practical impact. 25 references.

    2003-01-01

    The effects of Mn substitution on the structure and magnetic properties of the SeMO sub 3 (M = Cu sub 1 sub - sub x Mn sub x) solid solution have been studied. Rietveld refinements of the x-ray diffraction patterns of these samples indicate that the manganese ions occupy copper sites. This replacement induces significant changes in the M-O bond lengths that give rise to abrupt decreases of the [M-O sub 6] octahedral distortion. In contrast, the M-O(1)-M and M-O(2)-M bond angles remain essentially constant. The magnetic behaviour of this solid solution was studied in the temperature range of 2 K < T < 300 K. The temperature dependence of the inverse magnetic susceptibility is well described by the Curie-Weiss law at high temperatures, in the composition range studied. We found that the substitution of Mn for Cu induces a sharp drop in the saturation moment of SeCuO sub 3. At about 10% of Mn there is a change from positive to negative Weiss constant theta sub W that is mainly due to the [M-O sub 6] octahe...

    We report the first 3D spin liquid state of isotropic organic spins. Structural analysis, and magnetic and heat-capacity measurements were carried out for a chiral organic radical salt, (TBA) 1.5[(-)-NDI -Δ ] (TBA denotes tetrabutylammonium and NDI denotes naphthalene diimide), in which (-)-NDI -Δ forms a K4 structure due to its triangular molecular structure and an intermolecular π -π overlap between the NDI moieties. This lattice was identical to the hyperkagome lattice of S =1 /2 Mott dimers, and should exhibit 3D spin frustration. In fact, even though the high-temperature magnetic susceptibility followed the Curie-Weiss law with a negative Weiss constant of θ =-15 K , the low-temperature magnetic measurements revealed no long-range magnetic ordering down to 70 mK, and suggested the presence of a spin liquid state with a large residual paramagnetism χ0 of 8.5 ×10-6 emu g-1 at the absolute zero temperature. This was supported by the N 14 NMR measurements down to 0.38 K. Further, the low-temperature heat capacities cp down to 68 mK clearly indicated the presence of cp for the spin liquid state, which can be fitted to the power law of T0.62 in the wide temperature range 0.07-4.5 K.

During this year, the main emphasis will be given to study further the properties of HO 2 and O 2 - and OH, mainly in their role in biological systems. We will continue to study and elucidate how O 2 - reacts in biological systems. The toxicity of O 2 - is quite well established, but the mechanism is still obscure. The Haber Weiss reaction most probably can not account for the toxicity of O 2 - nor for the formation of singlet oxygen, nor of OH. We will study if reduction of Fe 3+ complexes by O 2 - in biological systems does catalyze the Haber Weiss reaction and if OH is formed in this mechanism. The role of oxygen, radiosensitizers in radiation damage of bacteriophages and cells will be further studied, as well as on E. Coli and Enzymes. We will try to elucidate the formation and role of OH, O 2 - and O 2 in these systems as well as the relative contribution of endogenous and exogenous damage, and the role of direct and indirect radiation damage to cells. We intend also to study if SOD (super oxide dismutase) does react only with O 2 - or also with biological peroxides (RO 2 ) and Hydroperoxides (RO 2 H). Further studies of O 2 - and O 2 with various cytochromes, and hemoglobins is planned

    Es wird ein statistisches Modell zum Einfluß der thermischen Bewegung auf die NMR-Linienform vorgestellt, das die Verschmälerung von Festkörper-Spektren bei wachsender Temperatur beschreibt. Das Modell geht von der Annahme aus, daß nach einer Ortsveränderung eines Kerns infolge thermischer Bewegung jede beliebige Kernresonanzfrequenz mit der durch das Festkörperspektrum vorgegebenen Wahrscheinlichkeit angenommen werden kann. Am Beispiel der Festkörper-Gaußlinie wird der Unterschied zu dem bekannten Modell von ANDERSON und WEISS verdeutlicht.Translated AbstractA Statistical Model for the Influence of Thermal Motion on N. M. R. Spectra in SolidsA theory is proposed which allows to describe the narrowing of n. m. r.-line width in the presence of thermal motions of the spins. The model is based on the assumption, that the local resonance frequency of a given spin immediately after the jump is distributed according to the n. m. r.-line shape of the rigid lattice. The difference to the well-known ANDERSON-WEISS-model of spectral narrowing is demonstrated for a gaussian line shape.

    One of the advantages of ion chromatography [Anal Chem. 47 (1975) 1801] as compared to other analytical techniques is that several ions may be analyzed simultaneously. One of the most important contributions of cation-exchange chromatography is its sensitivity to ammonium ion, which is difficult to analyze by other techniques [J. Weiss, in: E.L. Johnson (Ed.), Handbook of Ion Chromatography, Dionex, Sunnyvale, CA, USA]. The determination of low concentrations of ammonium ion in the presence of high concentrations of sodium poses a challenge in cation-exchange chromatography [J. Weiss, Ion Chromatography, VCH, 2nd Edition, Weinheim, 1995], as both cations have similar selectivities for the common stationary phases containing either sulfonate or carboxylate functional groups. The task was to develop a new cation-exchange stationary phase (for diverse concentration ratios of adjacent peaks) to overcome limitations experienced in previous trails. Various cation-exchange capacities and column body formats were investigated to optimize this application and others. The advantages and disadvantages of two carboxylic acid columns of different cation-exchange capacities and different column formats will be discussed.

    Full text: X-ray Reflectivity (XRR) over the last decade has proved to be a versatile and powerful technique by which the thickness of thin films, surface roughness and interface roughness can be determined. The systems amenable to study range from organic monolayers (liquid or solid substrates) to layered metal or semiconductor systems. Access to XRR has been limited by the requirement for synchrotron radiation sources. The development of XRR systems for the laboratory environment was pioneered by Weiss. An X-ray Reflectometer has been constructed by the Department of Physics (Australian Defence Force Academy) and the Research School of Chemistry (Australian National University). The general principles of the design were similar to those described by Weiss. The reflectometer is currently in the early stages of commissioning, with encouraging results thus far. The diffraction pattern of Mobil Catalytic Material (MCM), consisting primarily of SiO 2 . The poster will describe the reflectometer, its operation and present a summary of the most important results obtained to date

    The SQUID magnetic measurements were performed on the GaN films prepared by metal-organic vapour phase epitaxy and implanted by Tb{sup 3+}, Tm{sup 3+}, Sm{sup 3+}, and Ho{sup 3+} ions. The sapphire substrate was checked by the electron paramagnetic resonance method which showed a content of Cr{sup 3+} and Fe{sup 3+} impurities. The samples 5 × 5 mm{sup 2} were positioned in the classical straws and within an estimated accuracy of 10{sup −6 }emu, no ferromagnetic moment was detected in the temperature region of 2–300 K. The paramagnetic magnetization was studied for parallel and perpendicular orientation. In the case of GaN:Tb sample, at T = 2 K, a pronounced anisotropy with the easy axis perpendicular to the film was observed which can be explained by the lowest quasi-doublet state of the non-Kramers Tb{sup 3+} ion. The Weiss temperature deduced from the susceptibility data using the Curie-Weiss (C-W) law was found to depend substantially on the magnetic field.

    The magnetic susceptibility of liquid Cr-Au, Mn-Au, Fe-Au and Cu-Au alloys was investigated as a function of temperature and composition. Liquid Cr{sub 1-c}Au{sub c} with 0.5 ≤ c and Mn{sub 1-c}Au{sub c} with 0.3≤c obeyed the Curie-Weiss law with regard to their dependence of χ on temperature. The magnetic susceptibilities of liquid Fe-Au alloys also exhibited Curie-Weiss behavior with a reasonable value for the effective number of Bohr magneton. On the Au-rich side, the composition dependence of χ for liquid TM-Au (TM=Cr, Mn, Fe) alloys increased rapidly with increasing TM content, respectively. Additionally, the composition dependences of χ for liquid Cr-Au, Mn-Au, and Fe-Au alloys had maxima at compositions of 50 at% Cr, 70 at% Mn, and 85 at% Fe, respectively. We compared the composition dependences of χ{sub 3d} due to 3d electrons for liquid binary TM-M (M=Au, Al, Si, Sb), and investigated the relationship between χ{sub 3d} and E{sub F} in liquid binary TM-M alloys at a composition of 50 at% TM.

  14. Fluctuation relations for equilibrium states with broken discrete or continuous symmetries

    Isometric fluctuation relations are deduced for the fluctuations of the order parameter in equilibrium systems of condensed-matter physics with broken discrete or continuous symmetries. These relations are similar to their analogues obtained for non-equilibrium systems where the broken symmetry is time reversal. At equilibrium, these relations show that the ratio of the probabilities of opposite fluctuations goes exponentially with the symmetry-breaking external field and the magnitude of the fluctuations. These relations are applied to the Curie–Weiss, Heisenberg, and XY models of magnetism where the continuous rotational symmetry is broken, as well as to the q-state Potts model and the p-state clock model where discrete symmetries are broken. Broken symmetries are also considered in the anisotropic Curie–Weiss model. For infinite systems, the results are calculated using large-deviation theory. The relations are also applied to mean-field models of nematic liquid crystals where the order parameter is tensorial. Moreover, their extension to quantum systems is also deduced. (paper)

    We have investigated temperature-dependent magnetization (M), magnetic susceptibility (χ) and thermoelectric (S) properties of the electron-doped Ca{sub 0.85}Pr{sub 0.15}MnO{sub 3}. With decrease of temperature, paramagnetic (PM) to antiferromagnetic (AFM) phase transition occurs with a well-defined Néel temperature (T{sub N}=122 K). Magnetic susceptibility measurements reveal that the paramagnetic state involves modified Curie–Weiss paramagnetism. Field cooled and zero field cooled magnetization measurements indicate a signature of magnetic frustration. Ferromagnetic (FM) double-exchange interactions associated with doped e{sub g} electrons are favored over competing AFM interactions below T{sub irr}=112 K. Magnetization data also shows a second-order phase transition. The sign reversal in S(T) has been interpreted in terms of the change in the electronic structure relating to the orbital degrees of freedom of the doped e{sub g} electron. Low temperature (5–140 K) thermoelectric power, S (T) signifies the importance of electron–magnon scattering process. - Highlights: • Magnetic and thermoelectric properties have been investigated in Ca{sub 0.85}Pr{sub 0.15}MnO{sub 3}. • It shows a PM–AFM second order phase transition at T{sub N}=122 K. • PM state involves modified Curie–Weiss paramagnetism. • The electron–magnon scattering dominates temperature dependent thermoelectric power.

    Oncocytic adrenocortical neoplasms (OANs) are a rare but important subtype of adrenal tumors with unique clinical and morphological features. We present 13 previously unpublished cases, of which 3 were classified as benign, 2 as having borderline malignant potential, and 8 as malignant according to the Lin-Weiss-Bisceglia criteria. Seven tumors (54%) showed evidence of endocrine activity. All were composed of more than 90% oncocytes confirmed immunohistochemically using the antimitochondrial antibody mES-13 and ultrastructurally in 4 cases. Small oncocytes were a frequent finding that challenges the conventional notion of oncocytes as necessarily having abundant cytoplasm. Most cases were immunoreactive for vimentin, synaptophysin, inhibin-α, melan A, and calretinin, the latter being a novel finding in this group of neoplasms. Cytokeratin positivity with AE1/AE3 and CAM5.2 was variable. The literature was comprehensively reviewed to identify all cases of OANs reported to date. Hormone production is not as uncommon as previously believed, occurring in 30%. The Lin-Weiss-Bisceglia criteria were retrospectively applied to all published cases with sufficient information and were shown to effectively separate tumors according to their future risk of recurrence and survival using Kaplan-Meier survival curves (log-rank test, P interval = 27.5-88.5 months), providing the first preliminary evidence that the prognosis of malignant OANs is likely to be more favorable than conventional adrenocortical carcinomas, in which the reported median survival is between 14 and 32 months.

  17. Manifestations of Kitaev physics in thermodynamic properties of hexagonal iridates and α-RuCl3

    Science.gov (United States)

    Tsirlin, Alexander

    Kitaev model is hard to achieve in real materials. Best candidates available so far are hexagonal iridates M2IrO3 (M = Li and Na) and the recently discovered α-RuCl3 featuring hexagonal layers coupled by weak van der Waals bonding. I will review recent progress in crystal growth of these materials and compare their thermodynamic properties. Both hexagonal iridates and α-RuCl3 feature highly anisotropic Curie-Weiss temperatures that not only differ in magnitude but also change sign depending on the direction of the applied magnetic field. Néel temperatures are largely suppressed compared to the energy scale of the Curie-Weiss temperatures. These experimental observations will be linked to features of the electronic structure and to structural peculiarities associated with deviations from the ideal hexagonal symmetry. I will also discuss how the different nature of ligand atoms affects electronic structure and magnetic superexchange. This work has been done in collaboration with M. Majumder, M. Schmidt, M. Baenitz, F. Freund, and P. Gegenwart.

    Full Text Available La/Mn codoped BaTiO3 with different La2O3 content, ranging from 0.1 to 5.0 at% La, was investigated regarding their microstructural and dielectric characteristics. The content of 0.05 at% Mn was constant in all investigated samples. The samples were sintered at 1320°C and 1350°C for two hours. Microstructural studies were done using SEM and EDS analysis. The fine-grained microstructure was obtained even for low content of La. The appearance of secondary abnormal grains with serrated features along grain boundaries was observed in 1.0 at% La-BaTiO3 sintered at 1350°C. Nearly flat permittivity-temperature response was obtained in specimens with 2.0 and 5.0 at% La. Using the modified Curie-Weiss law a critical exponent γ and C’were calculated. The obtained values of γ pointed out the diffuse phase transformation in heavily doped BaTiO3 and great departure from the Curie-Weiss law for low doped ceramics.

    Highlights: ► New monovalent doped manganites Pr 0.6 Sr 0.4−x Na x MnO 3 (x = 0, 0.05). ► Comparison of electron magnetic resonance spectra in ferro- and paramagnetic phases. ► Double exchange interactions weakened by Na doping as indicated by activation energy. ► Magnetic susceptibility derived from resonance intensity obeys Curie–Weiss law. - Abstract: Effect of monovalent Na doping on the magnetic properties is studied in Pr 0.6 Sr 0.4−x Na x MnO 3 system (x = 0, 0.05) using X-band electron magnetic resonance and magnetization measurements. Temperature variation of magnetic resonance spectra of doped and undoped manganites is analyzed for paramagnetic and ferromagnetic states and compared to similar systems. In paramagnetic phase the magnetic susceptibility proportional to resonance signal intensity is found to obey the Curie–Weiss law. The effective magnetic moment becomes smaller in doped manganite. The paramagnetic Curie temperature derived from signal intensity equals to 312 and 306 K for the undoped and doped manganites, respectively, and is close to values obtained from magnetization variation in paramagnetic phase. The activation energy determined using the adiabatic small polaron hopping model is higher for the undoped than the doped manganite, which proves that the Na doping slightly reduces the Mn 3+ /Mn 4+ double exchange interactions.

    ADHD is a chronic disorder that generally has a negative effect on socio-personal adaptation. The objectives of the current study were to examine the adaptive functioning in the daily lives of adults with ADHD compared to adults without the disorder and to test the influence of ADHD symptoms and comorbid problems on different areas of adaptive functioning. Seventy-seven adults between 17 and 24 years old, 40 with a clinical diagnosis of combined-subtype ADHD in childhood and 37 controls, filled out the Weiss Functional Impairment Scale, the Weiss Symptom Record and Conners' Adult ADHD Rating Scale. Significant differences were found between adults with and without ADHD in family and academic functioning. Moreover, the ADHD symptomatology as a whole predicted significant deficiencies in the family environment and self-concept, whereas inattention specifically predicted worse academic performance and life skills. The comorbidities mainly affected the family and risky activity domains (dangerous driving, illegal behaviors, substance misuse and sexually inappropriate behaviors). The results illustrate the importance of developing a multimodal approach to helping ADHD adults cope with associated comorbid disorders, offering them supportive coaching in organizing daily activities, and incorporating the family and/or partner in the treatment plan.

    Human activity in the last century has led to a substantial increase in nitrogen (N) emissions and deposition (Galloway et al. 2003). Because of past, and, in some regions, continuing increases in emissions (Lehmann et al. 2005, Nilles and Conley 2001), this N deposition has reached a level that has caused or is likely to cause alterations and damage in many ecosystems across the United States. In some ecoregions, the impact of N deposition has been severe and has changed the biotic community structure and composition of ecosystems. In the Mediterranean California ecoregion, for example (see Chapter 13), replacement of native by exotic invasive vegetation is accelerated because exotic species are often more productive under elevated N deposition than native species in some California grasslands, coastal sage scrub, and desert scrub (Fenn et al. 2010, Rao and Allen 2010, Rao et al. 2010, Weiss 1999, Yoshida and Allen 2004). Such shifts in plant community composition and species richness can have consequences beyond changes in ecosystem structure: shifts may lead to overall losses in biodiversity and further impair particular threatened or endangered species (Stevens et al. 2004). Th e extirpation of the endangered checkerspot butterfl y (Euphydryas editha bayensis), because the host plant for the larval stage disappears in N-enriched ecosystems (Fenn et al. 2010, Weiss 1999), is just one example of the detrimental impacts of elevated N deposition.

  2. Methane production from stable manures

    Poch, M

    1955-04-01

    A brief description of the methane-bacteria is given, their classification, biochemistry, and ecology, and a table of gas production expected from a dozen waste materials. Descriptions of three fermentation systems are given. The Ducellier-Isman, Massaux consists of 2 or 3 tanks of 6 to 14 m/sup 3/ capacity which daily produces 5 to 17 m/sup 3/ gas. Rotted manure is placed in the tanks, covered with water and liquid manure, and allowed to ferment for 3 months. The older tanks are unmixed, but the newest have provision for breaking the scum layer. Gas production virtually ceases during the winter, much manual labor is involved, and high losses of organic matter are caused by use of already rotted manure. The Darmstadt system, developed by Reinhold and similar to the systems of Harnisch and Mueller, consists of a 15 m/sup 3/ covered pit into which farm wastes and household wastes are fed through piping. The tank is heated and stirred, solids making their way from one end of the tank to the outlet in a matter of weeks, from which they are shoveled and stacked. Gas production is 0.3 to 0.5 m/sup 3/ gas/m/sup 3/ tank daily. A good deal of manual labor is involved, and losses of nutrients occur after the solids are extracted from the tank and piled. A fully mechanized Schmidt-Egersgluess system, the Biological Humus Gasworks (Bihugas), consists of heated (30/sup 0/ to 35/sup 0/), mixed tanks, gas compressor, gas storage tank, and effluent storage tank. Three m/sup 3/ tank capacity are required per head of cattle and gas production is 2 to 2.5 m/sup 3//livestock unit/day. Straw is stored to be ready for use as fermentation feedstock when the cattle are in the fields. The length of digestion in the process is 18 to 20 days.

    Full Text Available Extreme environments, such as subterranean habitats, are suspected to be responsible for morphologically inseparable cryptic or sibling species and can bias biodiversity assessment. A DNA barcode is a short, standardized DNA sequence used for taxonomic purposes and has the potential to lessen the challenges presented by a biotic inventory. Here, we investigate the diversity of the genus Leptonetela Kratochvíl, 1978 that is endemic to karst systems in Eurasia using DNA barcoding. We analyzed 624 specimens using one mitochondrial gene fragment (COI. The results show that DNA barcoding is an efficient and rapid species identification method in this genus. DNA barcoding gap and automatic barcode gap discovery (ABGD analyses indicated the existence of 90 species, a result consistent with previous taxonomic hypotheses, and supported the existence of extreme male pedipalpal tibial spine and median apophysis polymorphism in Leptonetela species, with direct implications for the taxonomy of the group and its diversity. Based on the molecular and morphological evidence, we delimit and diagnose 90 Leptonetela species, including the type species Leptonetela kanellisi (Deeleman-Reinhold, 1971. Forty-six of them are previously undescribed. The female of Leptonetela zhai Wang & Li, 2011 is reported for the first time. Leptonetela tianxinensis (Tong & Li, 2008 comb. nov. is transferred from the genus Leptoneta Simon, 1872; the genus Guineta Lin & Li, 2010 syn. nov. is a junior synonym of Leptonetela; Leptonetela gigachela (Lin & Li, 2010 comb. nov. is transferred from Guineta.

    Spinal cord is one of the most important normal tissues that are aimed to be spared during radiation therapy of cancer. This organ has been known for its strongly serial character and its high sensitivity to radiation. In order to compare the sensitivity of different parts of spinal cord, the early data (1970's) for radiation myelopathy available in the literature could be used. In the present study the relative seriality model (Kallman et al. 1992) has been fitted to two different sets of clinical data for spinal cord irradiation: radiation myelitis of cervical spinal cord after treating 248 patients for malignant disease of head and neck (Abbatucci et al. 1978) and radiation myelitis of thoracic spinal cord after radiation treating 43 patients with lung carcinoma (Reinhold et al. 1976). The maximum likelihood method was applied for the fitting and the corresponding parameters together with their 68% confidence intervals calculated for each of the datasets respectively. The alpha-beta ratio for the thoracic survival was also obtained. On the basis of the present study the following conclusions can be drawn: 1. radiation myelopathy is a strongly serial endpoint, 2. it appears to be differences in radiosensitivity between the cervical and thoracic region of spinal cord, 3. thoracic spinal cord revealed very serial characteristic of dose response, while the cervical myelopathy seems to be a bit less serial endpoint, 4. the dose-response curve is much steeper in case of myelopathy of cervical spinal cord, due to the much higher gamma value for this region. This work compares the fitting of NTCP model to the cervical and thoracic regions of the spinal cord and shows quite different responses. In the future more data should be tested for better understanding the mechanism of spinal cord sensitivity to radiation

    Extreme environments, such as subterranean habitats, are suspected to be responsible for morphologically inseparable cryptic or sibling species and can bias biodiversity assessment. A DNA barcode is a short, standardized DNA sequence used for taxonomic purposes and has the potential to lessen the challenges presented by a biotic inventory. Here, we investigate the diversity of the genus Leptonetela Kratochvíl, 1978 that is endemic to karst systems in Eurasia using DNA barcoding. We analyzed 624 specimens using one mitochondrial gene fragment ( COI ). The results show that DNA barcoding is an efficient and rapid species identification method in this genus. DNA barcoding gap and automatic barcode gap discovery (ABGD) analyses indicated the existence of 90 species, a result consistent with previous taxonomic hypotheses, and supported the existence of extreme male pedipalpal tibial spine and median apophysis polymorphism in Leptonetela species, with direct implications for the taxonomy of the group and its diversity. Based on the molecular and morphological evidence, we delimit and diagnose 90 Leptonetela species, including the type species Leptonetela kanellisi (Deeleman-Reinhold, 1971). Forty-six of them are previously undescribed. The female of Leptonetela zhai Wang & Li, 2011 is reported for the first time. Leptonetela tianxinensis (Tong & Li, 2008) comb. nov. is transferred from the genus Leptoneta Simon, 1872; the genus Guineta Lin & Li, 2010 syn. nov. is a junior synonym of Leptonetela; Leptonetela gigachela (Lin & Li, 2010) comb. nov. is transferred from Guineta . The genus Sinoneta Lin & Li, 2010 syn. nov. is a junior synonym of Leptonetela ; Leptonetela notabilis (Lin & Li, 2010) comb. nov. and Leptonetela sexdigiti (Lin & Li, 2010) comb. nov. are transferred from Sinoneta ; Leptonetela sanchahe Wang & Li nom. nov. is proposed as a replacement name for Sinoneta palmata (Chen et al., 2010) because Leptonetela palmata is preoccupied.

    Full Text Available Le New Deal est le premier mouvement réformiste d’ampleur dans l’histoire des Etats‑Unis qui n’ait pas été inspiré, ni soutenu, par les forces du protestantisme. Si une majorité des protestants et de leur clergé se sont opposés au New Deal à partir de positions conservatrices, le théologien Reinhold Niebuhr en a développé au départ une virulente critique de gauche avant de finalement rallier le président démocrate à la fin des années trente. Nourrie par le rejet de l’idéalisme du Social Gospel, incapable à ses yeux de comprendre les rapports sociaux en terme de classe et de pouvoir, la critique de Niebuhr emprunte les outils d’analyse marxistes pour développer une approche réaliste, tant du point de vue des fins que des moyens de la lutte politique. Le New Deal lui apparaît avant tout comme un programme visant à sauver le capitalisme, alors que la société fondée sur la justice qu’il envisage passe par la socialisation des moyens de production qui ne pourra émerger qu’à travers des conflits sociaux au cours desquels les moyens de lutte même violents sont justifiés. Mais sous l’influence des évènements en Europe au lendemain de la victoire d’Hitler, Reinhold Niebuhr se tourne au milieu des années trente vers une réflexion théologique inspirée de l’orthodoxie de Karl Barth et de son frère Richard Niebuhr, qui l’amène à réintroduire le péché comme la limite absolue de toute l’expérience humaine, interdisant d’envisager la création d’une société de paix et de justice. Ce nouvel absolutisme théologique nourrit un relativisme politique, le réalisme chrétien consistant désormais à choisir la moins mauvaise des options en présence. De ce point de vue, le président démocrate qui appelle à la préparation militaire s’impose désormais comme le choix le plus réaliste face à la montée du fascisme en Europe.The New Deal was the first major reformist experiment in the

    Full Text Available The Cornell Net Carbohydrate and Protein System (CNCPS model has been increasingly used in tropical regions for dairy and beef production. However, the lack of appropriate characterization of the feeds has restricted its application. The objective of this study was to develop and evaluate a feed library containing feeds commonly used in tropical regions with characteristics needed as inputs for the CNCPS. Feed composition data collected from laboratory databases and from experiments published in scientific journals were used to develop this tropical feed library. The total digestible nutrients (TDN predicted at 1x intake of maintenance requirement with the CNCPS model agreed with those predicted by the Weiss et al. (1992 equation (r² of 92.7%, MSE of 13, and bias of 0.8% over all feeds. However, the regression r² of the tabular TDN values and the TDN predicted by the CNCPS model or with the Weiss equation were much lower (58.1 and 67.5%, respectively. A thorough comparison between observed and predicted TDN was not possible because of insufficient data to characterize the feeds as required by our models. When we used the mean chemical composition values from the literature data, the TDN predicted by our models did not agree with the measured values. We conclude using the TDN values calculated using the Weiss equation and the CNCPS model that are based on the actual chemical composition of the feeds result in energy values that more accurately represent the feeds being used in specific production situations than do the tabular values. Few papers published in Latin America journals that were used in this study reported information need by models such as the CNCPS.O uso do Sistema de Carboidrato e Proteina Líquidos da Universidade de Cornell (CNCPS tanto para produção de leite como carne tem aumentado durante o últimos anos nas regiões tropicais.

    It has recently been suggested that reentrant connections are essential in systems that process complex information [A. Damasio, H. Damasio, Cortical systems for the retrieval of concrete knowledge: the convergence zone framework, in: C. Koch, J.L. Davis (Eds.), Large Scale Neuronal Theories of the Brain, The MIT Press, Cambridge, 1995, pp. 61-74; G. Edelman, The Remembered Present, Basic Books, New York, 1989; M.I. Posner, M. Rothbart, Constructing neuronal theories of mind, in: C. Koch, J.L. Davis (Eds.), Large Scale Neuronal Theories of the Brain, The MIT Press, Cambridge, 1995, pp. 183-199; C. von der Malsburg, W. Schneider, A neuronal cocktail party processor, Biol. Cybem., 54 (1986) 29-40]. Reentry is not feedback, but parallel signalling in the time domain between spatially distributed maps, similar to a process of correlation between distributed systems. Accordingly, it was expected that during spontaneous reversals of the Necker cube, complex patterns of correlations between distributed systems would be present in the cortex. The present study included EEG (n=4) and MEG recordings (n=5). Two experimental questions were posed: (1) Can distributed cortical patterns present during perceptual reversals be classified differently using a generalised regression neural network (GRNN) compared to processing of a two-dimensional figure? (2) Does correlated cortical activity increase significantly during perception of a Necker cube reversal? One-second duration single trials of EEG and MEG data were analysed using the GRNN. Electrode/sensor pairings based on cortico-cortical connections were selected to assess correlated activity in each condition. The GRNN significantly classified single trials recorded during Necker cube reversals as different from single trials recorded during perception of a two-dimensional figure for both EEG and MEG. In addition, correlated cortical activity increased significantly in the Necker cube reversal condition for EEG and MEG compared

    There exist many methods for describing the complex relation between changes of gene expression in molecular pathways or gene ontologies under different experimental conditions. Among them, Gene Set Enrichment Analysis seems to be one of the most commonly used (over 10,000 citations). An important parameter, which could affect the final result, is the choice of a metric for the ranking of genes. Applying a default ranking metric may lead to poor results. In this work 28 benchmark data sets were used to evaluate the sensitivity and false positive rate of gene set analysis for 16 different ranking metrics including new proposals. Furthermore, the robustness of the chosen methods to sample size was tested. Using k-means clustering algorithm a group of four metrics with the highest performance in terms of overall sensitivity, overall false positive rate and computational load was established i.e. absolute value of Moderated Welch Test statistic, Minimum Significant Difference, absolute value of Signal-To-Noise ratio and Baumgartner-Weiss-Schindler test statistic. In case of false positive rate estimation, all selected ranking metrics were robust with respect to sample size. In case of sensitivity, the absolute value of Moderated Welch Test statistic and absolute value of Signal-To-Noise ratio gave stable results, while Baumgartner-Weiss-Schindler and Minimum Significant Difference showed better results for larger sample size. Finally, the Gene Set Enrichment Analysis method with all tested ranking metrics was parallelised and implemented in MATLAB, and is available at https://github.com/ZAEDPolSl/MrGSEA . Choosing a ranking metric in Gene Set Enrichment Analysis has critical impact on results of pathway enrichment analysis. The absolute value of Moderated Welch Test has the best overall sensitivity and Minimum Significant Difference has the best overall specificity of gene set analysis. When the number of non-normally distributed genes is high, using Baumgartner-Weiss

    Till date, the only consistent description of the deconfinement phase of the Sakai-Sugimoto model appears to be provided by the analysis of http://dx.doi.org/10.1007/JHEP09(2011)073. The current version of the analysis, however, has a subtlety regarding the monodromy of quarks around the Euclidean time circle. In this note, we revisit and resolve this issue by considering the effect of an imaginary baryon chemical potential on quark monodromies. With this ingredient, the proposal of http://dx.doi.org/10.1007/JHEP09(2011)073 for investigating finite temperature QCD using holography is firmly established. Additionally, our technique allows a holographic computation of the free energy as a function of the imaginary chemical potential in the deconfinement phase; we show that our result agrees with the corresponding formula obtained from perturbative QCD, namely the Roberge-Weiss potential.

    A Sm 7 Rh 3 single crystal with Th 7 Fe 3 -type hexagonal structure was grown by the Czochralski method. The magnetic and transport measurements revealed a uniaxial magnetocrystalline anisotropy in the magnetic susceptibility, magnetization and electrical resistivity. Sm 7 Rh 3 was found to exhibit antiferromagnetic transition at T N =54.0 K and another magnetic transition at T t =25.0 K. The specific heat data clearly showed the bulk nature of paramagnetic to ordered magnetic phase transition by the presence of a sharp peak at T N and a small anomaly at T t . The paramagnetic susceptibility does not obey the Curie–Weiss law, attributing to the temperature independent Van Vleck contribution and Pauli paramagnetism of conduction electrons. Metamagnetic phase transitions were observed along the c-axis in the ordered states. The magnetic field H–temperature T phase diagram was constructed. Anisotropic paramagnetic electrical resistivity showed the small negative temperature coefficients

    This motivating textbook gives a friendly, rigorous introduction to fundamental concepts in equilibrium statistical mechanics, covering a selection of specific models, including the Curie–Weiss and Ising models, the Gaussian free field, O(n) models, and models with Kać interactions. Using classical concepts such as Gibbs measures, pressure, free energy, and entropy, the book exposes the main features of the classical description of large systems in equilibrium, in particular the central problem of phase transitions. It treats such important topics as the Peierls argument, the Dobrushin uniqueness, Mermin–Wagner and Lee–Yang theorems, and develops from scratch such workhorses as correlation inequalities, the cluster expansion, Pirogov–Sinai Theory, and reflection positivity. Written as a self-contained course for advanced undergraduate or beginning graduate students, the detailed explanations, large collection of exercises (with solutions), and appendix of mathematical results and concepts also make i...

    The crystal structure of the fluorite-related praseodymium compounds with the composition Pr 3MO7, M = Nb, Ta, and Sb, have been determined using Rietveld refinement from X-ray and neutron powder diffraction data at 293 and 4 K. The structure described is orthorhombic with space group Cmcm (No. 63). It is a superstructure of the cubic fluorite structure with unit cell parameters a orth ≈ 2a c, b orth ≈ c orth ≈ a c2, as in La 3NbO 7. This structure consists of chains of corner linked MO 6 octahedra parallel with the c-axis. The magnetic susceptibility was measured between 4 and 300 K. The compounds obey the Curie-Weiss law including a Van Vleck temperature independent term. Pr 3SbO 7 shows a small deviation from this law below 25 K.

    We discuss the extension of gauge-invariant electric and magnetic screening masses in the quark-gluon plasma to the case of a finite baryon density, defining them in terms of a matrix of Polyakov loop correlators. We present lattice results for Nf=2 +1 QCD with physical quark masses, obtained using the imaginary chemical potential approach, which indicate that the screening masses increase as a function of μB. A separate analysis is carried out for the theoretically interesting case μB/T =3 i π , where charge conjugation is not explicitly broken and the usual definition of the screening masses can be used for temperatures below the Roberge-Weiss transition. Finally, we investigate the dependence of the static quark free energy on the baryon chemical potential, showing that it is a decreasing function of μB, which displays a peculiar behavior as the pseudocritical transition temperature at μB=0 is approached.

A large Curie-Weiss component is found in χ dc and the ESR spin susceptibility χ ESR of the pulverized 2201, 2212 and 2223 samples but it almost disappears by annealing. The relative magnitudes of χ ESR to χ dc for the annealed powders are dissimilar among the three phases: ESR of the 2201 sample is silent, χ ESR of the 2212 phase has almost the same magnitude as χ dc and χ ESR of the 2223 phase is appreciable but smaller than χ dc .

We argue that the observed departures from the Curie-Weiss behaviour manifest the onset of the quantum critical regime and formation of the Griffiths phase as a magnetic ground state of these spin species.

    We report on the magnetic susceptibility and Raman scattering measurements of the S = 1/2 three-dimensional (3D) spin web compound Cu 3 TeO 6 . The magnetic susceptibility shows an antiferromagnetic ordering at T N ∼61 K and a deviation from the Curie-Weiss law around 150 K. Raman spectra show the emergence of a new mode at 132 cm -1 for temperatures below T*∼50 K (∼0.8 T N ). At the same temperature, phonon anomalies in intensity and frequency show up. This gives evidence of pronounced magneto-elastic effects. In addition, we observe a two-magnon Raman spectrum around 214 cm -1 . Compared to typical 3D spin systems, its robust temperature dependence suggests that a frustrated spin topology with a reduced spin coordination number also enhances spin-phonon couplings.

Moreover, the description of the classification of minimal conformal models and Weiss-Lumino-Witten models, based on the simplest affine algebra is also given. Attempts to interpret and justify the appearance of A-D-E classification of algebra in W-Z-W model are made. Extensions of W-Z-W model, based on SU(N) level one, and the ways to deal with rank two Lie groups, using the arithmetics of quadratic intergers, are described

    Using thermodynamic measurements, neutron diffraction, nuclear magnetic resonance, and muon spin relaxation, we establish putative quantum spin-liquid behavior in Ba3InIr2O9 , where unpaired electrons are localized on mixed-valence Ir2O9 dimers with Ir4.5 + ions. Despite the antiferromagnetic Curie-Weiss temperature on the order of 10 K, neither long-range magnetic order nor spin freezing are observed down to at least 20 mK, such that spins are short-range correlated and dynamic over nearly three decades in temperature. Quadratic power-law behavior of both the spin-lattice relaxation rate and specific heat indicates the gapless nature of the ground state. We envisage that this exotic behavior may be related to an unprecedented combination of the triangular and buckled honeycomb geometries of nearest-neighbor exchange couplings in the mixed-valence setting.

    The size, surface and interface effects on the magnitude and stability of spontaneous polarization in a symmetric nanoscale ferroelectric capacitor were studied by analyzing its evolutionary trajectory based on a thermodynamic model. Analytic expressions of the Curie temperature, spontaneous polarization, critical thickness and the Curie-Weiss relation were derived, taking into account the effects of the depolarization field, built-in electric field, interfaces and surfaces. Our results show that the critical properties are not only functions of the ambient temperature, misfit strain and electromechanical boundary conditions, but also depend on the characteristics of electrodes, surfaces and interfaces, through the incomplete charge compensation, near-surface variation of polarization and work function steps of ferroelectric-electrode interfaces, which are adjustable.

  12. Experiments as to the influence of heat recovery from a bioreactor on sewage sludge disinfecting

    Energy Technology Data Exchange (ETDEWEB)

    Tarjanyi, J.; Strauch, D.; Philipp, W.

    The influence of heat recovery on the disinfecting effect of composting of sewage sludge in a bio-reactor (in-vessel-composting) was investigated in a reactor type Weiss-system Kneer. As test agents 3 different serovars of salmonella, Parvo- and Poliovirus and eggs of Ascaris suum were used. The experiments were done in a reactor which was fed with dewatered municipal sewage sludge mixed with waste-paper as C-carrier for better composting. Even under winter conditions the test agents were inactivated within the time which is characteristic for the passage of the composting material through the plug-flow reactor. These results cannot simply be applied without further investigation to other reactors of the same type but with different ways of operation. (orig.)

    In order to investigate the heavy-fermion like behavior of amorphous alloy Ce x Mn 100-x , the NMR measurements of 55 Mn (I=5/2 ) in Ce 65 Mn 35 have been carried out from 4.2 to 270 K using powdered sample. A broadened NMR spectrum containing five NQR lines split due to NQR interaction is observed. Quadrupole coupling constant 3e 2 Qq/2I(2I-1)h is gradually changed from about 1.8 MHz at 4.2 K to about 1.6 MHz at 270 K. Temperature dependence of the line width is expressed in the Curie-Weiss law with θ p =-10.5K. The value of Knight shift would be almost constant from 4.2 to 270 K

    Five problematic cases regarding the presence of reptile taxa on the island of São Tomé (Gulf of Guinea) are reviewed. These cases deal with 1) the past presence of crocodilians in the island, 2) the putative type locality of Dipsas pulverulenta Fischer, 1856, 3) the dubious presence of a mamba (genus Dendroaspis) on the island, 4) an erroneous reference to the presence of Gastropyxis smaragdina, and 5) two specimens (Psammophis lineatus and Psammophis elegans) from Carl Weiss collection, currently deposited in the Zoological Museum of Hamburg and wrongly labelled as being from São Tomé island. A provisional checklist to the terrestrial herpetofauna of the three oceanic islands of the Gulf of Guinea-São Tomé, Príncipe and Annobon-is presented in order to clarify the current numbers of the endemics of each island, as well as to review and present current research.

  15. Gasometer: An inexpensive device for continuous monitoring of dissolved gases and supersaturation

    1982-01-01

    The “gasometer” is a device that measures differential dissolved-gas pressures (δP) in water relative to barometric pressure (as does the “Weiss saturometer”), but operates continuously without human attention. The gasometer can be plumbed into a water-supply system and requires 8 liters/minute of water or more at 60 kilopascals. The gasometer's surfaces are nontoxic, and flow-through water can be used for fish culture. The gasometer may be connected to a small submersible pump and operated as a portable unit. The gasometer can activate an alarm system and thus protect fish from hyperbaric (supersaturation) or hypobaric gas pressures (usually due to low dissolved oxygen). Instructions are included for calculating and reporting data including the pressure and saturation of individual gases. Construction and performance standards are given for the gasometer. Occasional cleaning is required to remove biofouling from the gas-permeable tubing.PDF

    In this thesis the experimental study of the spin dynamics of solid {sup 3}He is described. By means of magnetization measurements above 3 mK a Curie-Weiss behaviour was found with {theta}{sub W}{approx}2.1 mK and by this an order parameter of J={theta}{sub W}k{sub B}/{approx}-0.5 Kk{sub B} was observed, while in the range of 1 to 3 mK a pure Curie behaviour was found. By means of NMR measurements the values of {tau}{sub 1}(6 mK)=240 ms{+-}12 ms and {tau}{sub 1}(1 mK){approx} 40 ms were determined, while spin-echo measurements yielded the spin-spin relaxation time {tau}{sub 2}(6 mK)=4540 {mu}s{+-}140 {mu}s. Furthermore neutron scattering studies were performed. (HSI)

    o-Tyrosine (o-Tyr) was used as a specific biomarker for OH radicals generated in biosystems. Specificity of o-Tyr as an OH biomarker was based on previous studied in systems exposed to ionizing radiations. Fresh muscle tissue incubated with benzene for 1 hr at 38 degree C exhibits formation of o-Tyr as seen in the cases of ethanol- and carbon tetrachloride-exposed systems. Gas chromatography/mass spectrometry selective ion monitoring measurements of o-Tyr yields in chicken breast muscle incubated with water or benzene indicate levels of less than 0.1 ppm and 3.0 ± 0.5 ppm of o-Tyr, respectively. Formation of OH is presumed to originate via a Haber-Weiss reaction of H 2 O 2 with Fe (II) preceded by the formation of O 2 and H 2 O 2 from distorted mitochondria

    The concentrations of the inorganic chemical elements presents in archaeological ceramic samples and clay samples allows the study about the clay sources determination used in the ceramic production. The analyzed samples are fragments of Brazilian indigenous ceramic, found in the area of the city of Londrina, North of Parana, and they belong to the archaeological collection of the 'Padre Carlos Weiss' Historical Museum, of the State University of Londrina. The determination of the chemical elements in these fragments was performed by energy dispersive X-ray microfluorescence (μ-XRF), for being not destructive and multielementar. The analytic technique allowed the identification of the K, Ca, Ti, Mn, Fe minority elements, and the Cr, Ni, Cu, Zn and Rb trace elements. The cluster analysis for the method of the medium grouping was used, and it was obtained two different groups, taking to conclude that indigenous Tupiguaranis used two clay sources in the making of its ceramic.

    1979-05-01

    A classical variational principle is constructed in the Weiss form, for dynamical systems with support spaces of the configuration-phase kind. This extended principle rules the dynamics of classical systems, partially Hamiltonian, in interaction with Lagrangean parameterized subsidiary dynamics. The variational family of equations obtained, consists of an equation of the Hamilton-Jacobi type, coupled to a family of differential equations of the Euler-Lagrange form. The basic dynamical function appearing in the equations is a function of the Routh kind. By means of an ansatz induced by the variationally obtained family, a generalized set of equation, is proposed constituted by a wave equation of Schroedinger type, coupled to a family of equations formaly analog to those Euler-Lagrange equations. A basic operator of Routh type appears in our generalized set of equations. This operator describes the interaction between a quantized Hamiltonian dynamics, with a parameterized classical Lagrangean dynamics in semi-classical closed models. (author) [pt

    The aim of this work is to investigate and compare ferro electrical properties of thin GeSbTe films with composition Ge{sub 4}Sb{sub 1}Te{sub 5} (with well defined ferro electrical properties) and Ge{sub 2}Sb{sub 2}Te{sub 5} using impedance, optical reflection, XRD, DSc and Piezo response Force Microscopy techniques. The temperature dependence of the capacitance in both materials shows an abrupt change at the temperature corresponding to ferroelectric-paraelectric transition and the Curie-Weiss dependence. In Ge{sub 2}Sb{sub 2}Te{sub 5} films this transition corresponds to the end from a NaCl-type to a hexagonal transformation. Piezo response Force Microscopy measurements found ferroelectric domains with dimension approximately equal to the dimension of grains. (Author)

    The crystalline and magnetic properties of 5% Mn and 5% Ni co-doped nanocrystalline ZnO particles, obtained by the co-precipitation method, are performed. X-ray diffraction data revealed that Zn0.90Mn0.05Ni0.05O crystallizes in the monophasic wurtzite structure. DC magnetization measurement showed that the samples are paramagnetic at room temperature. However, a large increase in the magnetization is observed below 50 K. This behavior, along with the negative value of Weiss constant obtained from the linear fit of magnetic susceptibility data below room temperature, indicates ferrimagnetic behavior. The ferrimagnetic properties observed at low temperature are explained and confirmed from ab-initio calculations using the Korringa-Kohn-Rostoker method combined with the coherent potential approximation.

    The authors combined affective events theory (H. M. Weiss & Cropanzano, 1996) and the transactional stress model (R. S. Lazarus & Folkman, 1984) to build and test a model specifying the dynamic, emotion-based relationships among challenge and hindrance stressors and citizenship and counterproductive behaviors. The study employed an experience sampling methodology. Results showed that challenge stressors had offsetting indirect links with citizenship behaviors through attentiveness and anxiety and a positive indirect effect on counterproductive behaviors through anxiety. Hindrance stressors had a negative indirect effect on citizenship behaviors through anxiety and a positive indirect effect on counterproductive behaviors through anxiety and anger. Finally, multilevel moderating effects showed that the relationship between hindrance stressors and anger varied according to employees' levels of neuroticism.

    Full Text Available The temperature dependence of the spontaneous polarization P is calculated in the ferroelectric phase of KH2PO4 (KDP at atmospheric pressure (TC = 122 K. Also, the dielectric constant ε is calculated at various temperatures in the paraelectric phase of KDP at atmospheric pressure. For this calculation of P and ε, by fitting the observed Raman frequencies of the soft mode, the microscopic parameters of the pure tunnelling model are obtained. In this model, the proton-lattice interaction is not considered and the collective proton mode is identified with the soft-mode response of the system. Our calculations show that the spontaneous polarization decreases continuously in the ferroelectric phase as approaching the transition temperature TC. Also, the dielectric constant decreases with increasing temperature and it diverges in the vicinity of the transition temperature (TC = 122 K for KDP according to the Curie-Weiss law.

    1987-03-01

    Magnetic and electrical properties of amorphous Mn-Y, Mn-Zr, and Mn-Nb alloys have been investigated. All these alloys have a temperature-dependent susceptibility which is well fitted by a Curie-Weiss law. This implies the existence of localized magnetic moments associated with the Mn atoms. In addition, amorphous Mn-Y alloys exhibit spin-glass characteristics at low temperature. The experimental results of the electrical resistivity show that the temperature coefficient of resistivity (TCR) of both Mn-Y and Mn-Zr are negative, while Mn-Nb has a positive TCR. On the other hand, the resistivity-temperature curves of Mn-Zr and Mn-Nb have nearly the same tendency but are different from that of Mn-Y.

    We report an experimental study of the crystallographic lattice, morphologic characteristics and magnetic feature of Sr 2 RuHoO 6 complex perovskite, which is used as a precursor in the fabrication process of the superconducting ruthenocuprate RuSr 2 HoCu 2 O 8 . The samples were produced through the standard solid state reaction. A Rietveld refinement of experimental X-ray diffraction patterns shows that the material crystallizes in a monoclinic structure, which belongs to the P21/n (no.14) space group, with lattice parameters a=5.7719(6) Å, b=5.8784(5) Å, c=8.1651(9) Å, and tilt angle β=90.200°. Magnetic susceptibility measurements reveal the occurrence of an antiferromagnetic ordering for a Néel temperature T N =10.1 K. From the Curie-Weiss fitting of the paramagnetic regime we obtain an effective magnetic moment of 11.31 μ B .

    The purpose of the current investigation was to examine friendship quality with a best friend in youth disability sport with an international sample of moderately experienced athletes with disabilities ages 9 to 18 years. Participants were 85 males and 65 females from four countries who competed in track and field and swimming. Data were collected with the Sport Friendship Quality Scale (Weiss & Smith, 1999). An exploratory factor analyses indicated that participants viewed their friendship quality with a best friend in disability sport as having both positive and negative dimensions. The latter focused exclusively on conflict experiences. Females reported stronger perceptions of the benefits of their friendships than males did; whereas no gender differences occurred in perceptions of the negative aspects to friendships. Item analyses indicated that females scored higher than males on questions reflecting loyalty, providing intimacy, self-esteem, supportiveness, having things in common, and playing together.

    By means of the time-differential perturbed angular gamma distribution after a nuclear reaction (TDPAD) the g-values of the isomer 1 1/2 - states are measured in 145 Eu and 147 Eu in the host metal Sm. The results are g ( 145 Eu) = + 1.356 + 0.008 g ( 147 Eu) = + 1.28 +- 0.01. The temperature dependence of the paramagnetic correction β obeys a Curie-Weiss law β = 1 + C/CT-, with C = -(50 +- 2) K and THETA = -(29 +- 5) K between 90 K and 1000 K, for both systems, 145 EU Sm and 147 Eu Sm. For room temperature the quadrupole coupling constant νsub(Q) is determined for 145 Eu Sm for the 1 1/2 - state: νsub(Q) = (12.5 +- 0.5) MHz and the paramagnetic relaxation time tausub(p) >= 1 μs. The g values are investigated also theoretically. (BHO)

    The magnetic properties of compounds UMn 2 and UCo 2 , and solid solutions UMn 2 -UFe 2 and UMn 2 -UCo 2 have been examined. It has been established, that in substituting iron ions with manganese ions, the temperature of the ferromagnetic transformation of UFe 2 decreases, and within the region of 50 at.% UFe 2 the ferromagnetic ordering disappears. The Curie-Weiss law holds within a limited temperature range. In the solid solutions of two paramagnets UMn 2 and UCo 2 , which are independent of temperature, at a concentration of 45 to 50 at.% UCo 2 , the magnetic susceptibility and its dependence on temperature attain their maximum values. The results obtained are connected with the collectivization of d-, f-, and s-electrons of an alloy

    2002-03-01

    Magnetic interactions in organic conductors including magnetic anions, such as λ-(BETS)2FeCl4 and κ-(BETS)2FeX4 [X = Cl and Br], are estimated from intermolecular overlap integrals; the overlaps between anions afford Jdd, and those between anions and donors give Jπ d. From this, the most stable spin alignments are decided, and such quantities as the Néel and Weiss temperatures, as well as the magnitude of spin polarization on the π-molecules are evaluated on the basis of the mean-field theory of πd-systems. The calculation is extended to several other πd-conductors, which are classified depending on the relative magnitudes of the direct dd- and indirect πd-interactions.

    Full Text Available Lithium-based cells LiCo2O4 have been characterized by magnetic techniques, looking at the influence of the partial substitution of cobalt by 3d or 4d transition metal elements (Fe, Ni, Cu, Cr, Mo. The non-substituted compound LiCo2O4 behaves as an antiferromagnet, with a Néel temperature TN of 30 K, although antiferromagnetic interactions are much more important, as suggested by a Weiss parameter Θ of the order of ‑225 K. In the solid solution Li(NixCo2‑xO4 the Weiss parameter Θ changes with x(Ni, reaching large positive values (e.g., Θ ~ +230 K, for x = 0.5. This phenomenon suggests the existence of a canted‑antiferromagnetic or ferrimagnetic structures with large ferromagnetic components. Substitution of cobalt by other 3d or 4d transition metals in the LiMe0.5Co1.5O4 series shows dramatic effects with respect to the non-substituted LiCo2O4 compound : copper completely suppresses the magnetic order, while iron increases TN to almost room temperature. No modifications are observed when molybdenum substitutes cobalt, while chromium transforms the AF order in a ferromagnetic one, with Tc of about 90 K.Se ha caracterizado por técnicas magnéticas, el efecto de la sustitución parcial de Co por elementos de transición 3d o 4d (Fe, Ni, Cu, Cr, Mo en celdas LiCo2O4 a base de litio.

    {sup 121}Sb and {sup 19B}Pt nuclear magnetic resonance (NMR) has been studied in the half-Heusler type compound YbPtSb to obtain information on local magnetic behavior. The characteristics of the localized 4f spins are observed in the Cuire-Weiss type behavior of the Knight shifts K for both {sup 121}Sb and {sup 19B}Pt. From the slope of K-{sub {chi}} plots we estimated hyperfine coupling constants of -3.8 and -4.6 kOe/{mu}{sub B} at Sb and Pt sites, respectively. It was found that the spin-echo decay rate 1/T{sub 2} of {sup 121}Sb shows a clear peaks at 10 K. Similar tendency was also observed in case of {sup 19B}Pt. However, static properties do not show any anomalies near 10 K.

During dehydration process the water molecules are lost in two stages. The magnetic susceptibility data for this complex change with temperature according to the Curie-Weiss law with Θ = -35 K. The magnetic moment values decrease from 5.00μ B at 303 K to 4.38μB at 76 K. (author)

    Full Text Available We consider an open-loop system of a fourth order Schrodinger equation with variable coefficients and Neumann boundary control and collocated observation. Using the multiplier method on Riemannian manifold we show that that the system is well-posed in the sense of Salamon. This implies that the exponential stability of the closed-loop system under the direct proportional output feedback control and the exact controllability of open-loop system are equivalent. So in order to conclude feedback stabilization from well-posedness, we study the exact controllability under a uniqueness assumption by presenting the observability inequality for the dual system. In addition, we show that the system is regular in the sense of Weiss, and that the feedthrough operator is zero.

    A solubility limit of approx. 6 mol % PuO 2 in sodium disilicate (Na 2 O.2SiO 2 ) glass has been determined. Magnetic susceptibility measurements on these glasses yield approximate Curie-Weiss behavior, in contrast to the temperature-independent susceptibility of crystalline PuO 2 . This result is interpreted to indicate that the local site symmetry around the Pu ion in the sodium disilicate glass is much different than in crystalline PuO 2 . The effective paramagnetic moments determined from the temperature dependence of the susceptibility are found to be consistent with calculated free-ion values based on the most likely 5f electron configurations

    Measurements of magnetic susceptibility of erbium-yttrium alumogarnets in the 0.04-4.2 K temperature range are carried out. (Er x I 1-x ) 3 Al 5 O 12 monocrystals were grown by the method of vertical directed crystallization. The specimens were produced as 5 cm high cylinders 0.63 cm in diameter; the axis of the cylinders coincided with the (100) direction of the crystals. Magnetic susceptibility was measured by the Harsthorn bridge method at the frequency of 33 Hz. The analysis of measurement results shows that susceptibility of the investigated crystals at T >or approx. 2T N is well described by the Curie-Weiss law. Existence of threshold concentration of the magnetic component testifies to an essential role of exchange interactions in establishment of the magnetic order in Er 3 Al 5 O 12

    The magnetic behavior of sputtered and pulsed laser deposited (PLD) Fe x Ag 100-x thin films with 27≤x≤55 has been studied by means of ac and dc magnetic measurements. Sputtered samples present a continuous decrease in the magnetization, down to 310 K for x=30, where a magnetic transition into a superparamagnetic state with the presence of dipolar interactions is observed. The ac susceptibility measurements indicate that this transition resembles that of three dimensional glassy systems. Sputtered samples with higher concentration of Fe present a similar but slower thermal evolution of magnetization. PLD samples with x≥50 show a Curie-Weiss-type transition above ∼200 K triggered by direct exchange interactions. As the temperature decreases, the system behaves like a ferromagnet and below ∼75 K, a transition into a cluster-glass state appears. As the composition decreases, these phenomena vanish

    For second countable discrete quantum groups, and more generally second countable locally compact quantum groups with trivial scaling group, we show that property (T) is equivalent to every weakly mixing unitary representation not having almost invariant vectors. This is a generalization of a theorem of Bekka and Valette from the group setting and was previously established in the case of low dual by Daws, Skalski, and Viselter. Our approach uses spectral techniques and is completely different from those of Bekka-Valette and Daws-Skalski-Viselter. By a separate argument we furthermore extend the result to second countable nonunimodular locally compact quantum groups, which are shown in particular not to have property (T), generalizing a theorem of Fima from the discrete setting. We also obtain quantum group versions of characterizations of property (T) of Kerr and Pichot in terms of the Baire category theory of weak mixing representations and of Connes and Weiss in terms of the prevalence of strongly ergodic actions.

    2009-07-01

    Social interaction and development of friendships between children with and without a disability are often proposed as potential outcomes of inclusive education. Physical activity specialists assert that exercise and sport environments may be conducive to social and friendship outcomes. This study investigated friendship in inclusive physical education from the perspective of students with (n = 8) and without (n = 8) physical disabilities. All participants attended a reversely integrated school and were interviewed using a semistructured, open-ended format. An adapted version of Weiss, Smith, and Theeboom's (1996) interview guide exploring perceptions of peer relationships in the sport domain was used. Four conceptual categories emerged from the analysis: development of friendship, best friend, preferred physical activities and outcomes, and dealing with disability. The results demonstrated the key characteristics of best friends and the influential role they play.

    2010-12-01

    We investigate the singularity structure analysis of the higher-dimensional time-gated Manakov system referring to the (2+1)-dimensional coupled nonlinear Schroedinger (CNLS) equations, and we show that these equations are Painleve-integrable. By means of the Weiss et al.'s methodology, we show the arbitrariness of the expansion coefficients and the consistency of the truncation corresponding to a special Baecklund transformation (BT) of these CNLS equations. In the wake of such transformation, following the Hirota's formalism, we derive a one-soliton solution. Besides, by using the Zakharov-Shabat (ZS) scheme which provides a general Lax-representation of an evolution system, we show that the (2+1)-dimensional CNLS system under interests is completely integrable. Furthermore, using the arbitrariness of the above coefficients, we unearth and investigate a typical spectrum of periodic coherent structures while depicting elastic interactions amongst such patterns.

    In the framework of the IEA Task 32 (Solar Heating and Cooling Programme), we developed a numeric model to simulate heat transfer in phase change materials (PCM), and experimental data. The analyzed system is bulk PCM plunged in a water tank storage of a solar combisystem (heating and domestic hot water production). The numerical model, based on the enthalpy approach, takes into account hysteresis and subcooling characteristic and also the conduction and the convection in the PCM. This model has been implemented in an existing TRNSYS type of water tank storage. The simulations has been compared with experimental data obtained with a solar installation using water tank storage of about 900 litres, already studied during the IEA Task 26 (Weiss 2003).

    Lix(Ni0.4Mn0.6)2-xO2 (1.09hydroxide as raw materials. All the compounds have a layered rock-salt structure, and the cation mixing degree (Ni2+ occupancy in the Li-layer) decreases with an increase in x. From the low-temperature magnetic measurement, they all have negative Weiss temperature and spontaneous magnetization, that is, they are ferromagnetic materials. Both the Curie temperature and the spontaneous magnetization at 4.2K decrease with an increase in x. These magnetic variations are attributed to the lowering of the cation mixing degree: the magnetic interaction network turns to two-dimensional one with the loss of the inert-layer coupling. These situations may be considered semi-quantitatively using the ferromagnetic cluster model. Additionally, the cation mixing degree has an influence on their electrochemical properties such as cycle fading and rate capability.

    Fe substitution effect on the magnetic behavior of Mn2-xFexBO4 (x = 0.3, 0.5, 0.7) warwickites has been investigated combining Mössbauer spectroscopy, dc magnetization, ac magnetic susceptibility, and heat capacity measurements. The Fe3+ ions distribution over two crystallographic nonequivalent sites is studied. The Fe introduction breaks a long-range antiferromagnetic order and leads to onset of spin-glass ground state. The antiferromagnetic short-range-order spin correlations persist up to temperatures well above TSG reflecting in increasing deviations from the Curie-Weiss law, the reduced effective magnetic moment and "missing" entropy. The results are interpreted in the terms of the progressive increase of the frustration effect and the formation of spin-correlated regions.

    This thesis is devoted to a study of dipolar magnetism of the proton spins in Ca(OH) 2 . First, cooling techniques are described. The energy of different spin configurations are calculated in the Weiss-field approximation. Crystallographic characteristics of Ca(OH) 2 are described, as well as a method to produce monocrystals and a method for crystal doping using 1.5 MeV electron beams. It is shown that the polarization mechanism of the proton spins in Ca(OH) 2 doped with O 2 - centra is the 'Solid Effect'. Susceptibility measurements are presented as a function of the polarization. Results imply that both at positive and at negative temperatures state ordering sets in, characterized by a plateau in the susceptibility. (Auth/G.J.P.)

    Formation of two more new materials, Pr 2 Ni 3 Si 5 and Ho 2 Ni 3 Si 5 , of the series, R 2 Ni 3 Si 5 (R = rare earth and Y) and their magnetic properties are reported here. These materials crystallize in the orthorhombic U 2 Co 3 Si 5 -type structure (space group Ibam). Magnetic susceptibility measurement in the temperature range 5 K--300 K show that the compound Pr 2 Ni 3 Si 5 order antiferromagnetically at T N ∼ 8.5 K and Ho 2 Ni 3 Si 5 at ∼ 6 K. Considering T N (Gd 2 Ni 3 Si 5 ) ∼ 15 K, T N (Pr 2 Ni 3 Si 5 ) ∼ 8.5 K is rather high. The magnetic susceptibility of both of the materials, in the paramagnetic state, follows a Curie-Weiss law with effective moment close to that of the corresponding free trivalent rare earth ion

    NpBr 4 was studied by 237 Np Moessbauer resonance from 4.2 to 20 0 K and by vibrating-sample magnetometer from 2.2 to 70.5 0 K. The magnetic susceptibility exhibits typical Curie-Weiss behavior about 20 0 K and displays a sharp peak at 12.5 +- 0.5 0 K indicating an antiferromagnetic transition. The Moessbauer spectrum at 4.2 0 K agrees with previous work by Stone and Pillinger [J.A. Stone and W.L. Pillinger, Sym. Faraday Soc., 1, 77(1967)]. At approximately 13 0 K, there is a small decline in H/sub eff/ with paramagnetic relaxation effects remaining at higher temperatures. (U.S.)

    An outline of the physical concepts evolution is given from the ancient philosophers to the present time. With qualitative explanations about the meaning of the theories that is the milestones of these concepts evolution, it mentions the ideas which lead the studies to the conception of a unified field theory. Chronologically, it has brief information about the ideas of Laplace (mechanical determinism), Maxwell (the field concept), Einsten (the space-time structure), Heisenberg and Schroedinger (the quantum mechanics), Dirac (the relativistic quantum and the antiparticles), Gell-Mann (the quarks), Weinberg-Salam (Weak interactions and eletromagnetic unification), H. Georgi and S. Glashon (strong interactions plus Weinberg-Salam), Kaluza-Klein (a fifth space-time coordinate), and Zumino-Weiss (supersymmetry and supergravity). (G.D.F.) [pt

    Measurements of the magnetic susceptibility of powdered samples of Dy 2 (MoO 4 ) 3 , Ho 2 (MoO 4 ) 3 and Er 2 (MoO 4 ) 3 in the temperature range 300 to 920 K are reported. The Curie Weiss Law is obeyed and yields the magneton numbers 10.72, 10.68 and 9.68 for the Dy 3+ , Ho 3+ and Er 3+ ions, respectively, the theoretical values being 10.63, 10.60 and 9.60. The results are analysed in terms of molecular field theory and it is predicted that Dy 2 (MoO 4 ) 3 , Ho 2 (MoO 4 ) 3 and Er 2 (MoO 4 ) 3 become ferromagnetic below 12, 17 and 5 K, respectively.

    2003-01-01

    The one-dimensional (1D) generalized modified complex Ginzburg-Landau (MCGL) equation for the traveling wave systems is analytically studied. Exact solutions of this equation are obtained using a method which combines the Painleve test for integrability in the formalism of Weiss-Tabor-Carnevale and Hirota technique of bilinearization. We show that pulses, fronts, periodic unbounded waves, sources, sinks and solution as collision between two fronts are the important coherent structures that organize much of the dynamical properties of these traveling wave systems. The degeneracies of the 1D generalized MCGL equation are examined as well as several of their solutions. These degeneracies include two important equations: the 1D generalized modified Schroedinger equation and the 1D generalized real modified Ginzburg-Landau equation. We obtain that the one parameter family of traveling localized source solutions called 'Nozaki-Bekki holes' become a subfamily of the dark soliton solutions in the 1D generalized modified Schroedinger limit

    Protective effects of Aloe arborescens (AA) on mouse skin injury induced by soft X-irradiation were examined. The mechanisms on radiation protection by measuring scavenge activity of activated oxygen, protective effects of nucleic acid, induction of antioxidative protein and so on were further investigated. Consequently a significant protective effect of skin injury was observed in AA S6-3-b. As the mechanisms of radiation protection in AA, the following matters were found. AA S6-3-b showed scavenge activity of hydroxyl radicals generated by Haber-Weiss reaction. AA S6-3-b suppressed the changes of activity in superoxide dismutase and gluthathione peroxidase at 7d after soft X-irradiation. Metallothionein was induced in the skin and liver against normal mice at 24 h after administration of AA S6-3-b. (author)

    A suddenly-introduced axial through-crack in the wall of a pipe pressurized by hot water is allowed to propagate according to Weiss' notch-strength theory of ductile static fracture. The dynamic-fracture criterion used enabled the authors to obtain a unique comparison of the results of ductile-fracture with those of brittle-fracture in a fracturing A533B steel pipe. Since the pipe cross-sectional area is likely to increase with large flap motions under ductile tearing, a large deformation shell-finite-difference-dynamic-code which includes rotary inertia was used in this analysis. The uniaxial-stress-strain curve of A533B steel was approximated by a bilinear-stress-strain where Von-Mises yield criterion and associated flow rule were used in the elastic-plastic analysis. The fluid pressure was assumed constant and thus pipe flaps are only lightly loaded by pressure in this analysis. (Auth.)

    We have investigated structural, magnetic and dielectric properties of Fe{sub 2}TeO{sub 6} which is a magnetoelectric antiferromagnet with the trirutile lattice. Rietveld analysis of room temperature X-ray diffraction data shows the phase purity of the sample with tetragonal trirutile structure (space group P4{sub 2}/mnm). The DC susceptibility measurement performed on polycrystalline powders exhibits antiferromagnetic ordering below transition temperature ~ 210K. The employment of Curie-Weiss law to inverse magnetic susceptibility only in the temperature range 350-260 K indicates the magnetic ordering starts developing before the transition temperature. The temperature dependent dielectric measurements show an intrinsic behavior of dielectric constant below 150 K while a continuous increase in dielectric constant with temperature above 150 K may be attributed to a small increase in electrical conduction, known commonly in the literatures.

    The physics of the dHvA effect is discussed and it is shown how it can be used to determine the Fermi surface geometry, the Fermi velocities and the local scattering rates. Dingle temperature measurements are discribed and discussed. Furthermore the way in which the samples were prepared is described. Also discussed are some aspects of the metallurgical behavior of hydrogen in copper which are relevant to the sample preparation such as solubility, diffusion, precipitation, and trapping at impurities. The experimental results are presented, and the local scattering rates are determined from the results. These are then compared with lifetimes from previously reported measurements on substitutional impurities in noble metals. The experimental results are found to be in excellent agreement with a recent calculation of the scattering rates for hydrogen in copper by Huisman and Weiss. The data is also analysed in terms of phase shifts using the Greens function theory of Holtzworth and Lee for scattering from interstitials. (HPOE) [de

    Vanadium dibromide, along with VCl 2 and VI 2 , has a hexagonal crystal structure (CdI 2 structure) in which the magnetic coupling of vanadium ions within the c planes is much stronger than the interplane coupling. These systems are of interest as possible examples of highly frustrated two-dimensional triangular lattice antiferromagnets. This interest is encouraged by high-temperature magnetic susceptibility measurements, which yield Weiss constants of several hundred degrees Kelvin. In fact, magnetic transitions do not occur in these substances until temperatures of less than 50 K are reached, indicating that the antiferromagnetic interactions are frustrated. A search for possible new transitions at very low temperatures was conducted with a VBr 2 single-crystal sample mounted in the dilution refrigerator neutron diffraction facility at HFIR. The crystal was not of very good quality, but three distinct magnetic reflections were observed at 4.2 K and below

    In the present study, a barium strontium bismuth titanate (Ba 0.25 Sr 0.75 Bi 4 Ti 4 O 15 , BSBT) ceramic composition has been prepared by conventional solid-state reaction. In order to study the structure of as synthesized BSBT ceramics, the X-ray powder diffraction (XRD), Raman and FTIR studies have been carried out on the powdered sample. X-ray diffraction analysis confirms the formation of a single phase four-layer Aurivillius-type ceramics that crystallizes in an orthorhombic structure with A2 1 am space group. The dielectric properties of the ceramics have been studied in the temperature range 30 - 600℃ temperature range at various frequencies (100 Hz to 1 MHz). A sharp dielectric anomaly was observed at ∼ 485℃ at all the frequencies corresponding to the ferroelectric to paraelectric phase transition. The ferroelectric behavior is confirmed from the Curie-Weiss law fitting of the dielectric data. (author)

    Zn{sub 1-} {sub x} Mn {sub x} O crystallites were synthesized by hydrothermal method. X-ray diffraction, UV-Vis absorption spectroscopy, and electron paramagnetic resonance (EPR) spectra confirm the substitution of Zn site by Mn{sup 2+} ion. The nonmonotonic variation of band gap exhibits that the short-ranged interactions between the d electrons of Mn and the s and p electrons of the host bands are dominated at lower Mn concentration (x). EPR spectra show that Mn{sup 2+} is in exchange interaction at higher x. By using a Curie-Weiss equation on the EPR data, it is found that the dominant magnetic property is antiferromagnetic for higher x, and paramagnetic for lower x.

Despite the diagnostic and therapeutic capabilities of upper endoscopy, there is still significant associated morbidity and mortality in patients experiencing acute UGIB, thus this is a true GI emergency. Acute UGIB is divided into non-variceal and variceal causes. The most common type of acute UGIB is 'non-variceal' and includes diagnoses such as peptic ulcer (gastric and duodenal), gastroduodenal erosions, Mallory-Weiss tears, erosive oesophagitis, arterio-venous malformations, Dieulafoy's lesion, and upper GI tract tumours and malignancies. This article focuses exclusively on initial management strategies for acute upper GI bleeding. We discuss up to date and evidence-based strategies for patient risk stratification, initial patient management prior to endoscopy, potential causes of UGIB, role of proton pump inhibitors, prokinetic agents, prophylactic antibiotics, vasoactive pharmacotherapies, and timing of endoscopy.

    Spontaneous total avascular necrosis of the tarsal navicula has been well documented in children (Kohler's disease) but is uncommon in adults where partial necrosis is usually seen after trauma or in Müller-Weiss disease. A case of spontaneous complete navicular osteonecrosis in a 46 year old female is described; she had accompanying Mee's leuchonychial lines in the toenails of the great and second toes only; the lines resolved after 9 months. She has been treated with an excision of the navicula and interpositional iliac crest bone graft talo-cuneiform fusion with resolution of her pain. It is postulated that the combination of the Mee's lines and avascular necrosis of the navicula indicates an occlusion of the dorsalis pedis in a predisposed individual.

    Mairesse, Olivier; Hofmans, Joeri; Theuns, Peter

    2008-05-01

    We propose a free, easy-to-use computer program that does not requires prior knowledge of computer programming to generate and run experiments using textual or pictorial stimuli. Although the FM Experiment Builder suite was initially programmed for building and conducting FM experiments, it can also be applied for non-FM experiments that necessitate randomized, single, or multifactorial designs. The program is highly configurable, allowing multilingual use and a wide range of different response formats. The outputs of the experiments are Microsoft Excel compatible .xls files that allow easy copy-paste of the results into Weiss's FM CalSTAT program (2006) or any other statistical package. Its Java-based structure is compatible with both Windows and Macintosh operating systems, and its compactness (< 1 MB) makes it easily distributable over the Internet.

  12. Radiation chemistry: basic, strategic or tactical science?

    International Nuclear Information System (INIS)

    Wardman, Peter

    1989-01-01

    The work of Weiss in the 1930s, particularly with Haber, has only recently been recognized to have implications in biology and medicine. Similarly, research in radiation chemistry and the application of the pulse radiolysis technique, for example, have implications far beyond traditional radiation chemistry. Some examples of such research are discussed against a background of categorization into 'basic', 'strategic' or 'tactical' science. Examples discussed include redox properties of free radicals, and the identification and characterization of nitro radicals as intermediates in drug metabolism. Radical reactions often take place in multicomponent systems, and the techniques of radiation chemistry can be used to probe, for example, events occurring at interfaces in micelles. Industrial processes involving radiation are attracting investment, particularly in Japan. (author)

  13. Infinity properads and infinity wheeled properads

    Hackney, Philip; Yau, Donald

    2015-01-01

    The topic of this book sits at the interface of the theory of higher categories (in the guise of (∞,1)-categories) and the theory of properads. Properads are devices more general than operads, and enable one to encode bialgebraic, rather than just (co)algebraic, structures.   The text extends both the Joyal-Lurie approach to higher categories and the Cisinski-Moerdijk-Weiss approach to higher operads, and provides a foundation for a broad study of the homotopy theory of properads. This work also serves as a complete guide to the generalised graphs which are pervasive in the study of operads and properads. A preliminary list of potential applications and extensions comprises the final chapter.   Infinity Properads and Infinity Wheeled Properads is written for mathematicians in the fields of topology, algebra, category theory, and related areas. It is written roughly at the second year graduate level, and assumes a basic knowledge of category theory.

  14. Response functions of free mass gravitational wave antennas

    1985-01-01

    The work of Gursel, Linsay, Spero, Saulson, Whitcomb and Weiss (1984) on the response of a free-mass interferometric antenna is extended. Starting from first principles, the earlier work derived the response of a 2-arm gravitational wave antenna to plane polarized gravitational waves. Equivalent formulas (generalized slightly to allow for arbitrary elliptical polarization) are obtained by a simple differencing of the '3-pulse' Doppler response functions of two 1-arm antennas. A '4-pulse' response function is found, with quite complicated angular dependences for arbitrary incident polarization. The differencing method can as readily be used to write exact response functions ('3n+1 pulse') for antennas having multiple passes or more arms.

    2013-12-01

    Full Text Available This collection of eight biographical essays from a 2007 symposium makes for engaging reading and holds together well as a book. The authors, mainly anthropologists, examine the lives of ten explorers who were active primarily in the first half of the twentieth century. Some worked for decades in the Chinese borderlands. Several became quite well-known and influential figures during their lifetime and after, such as Joseph Rock, but it is likely that most of the explorers featured here will be new to readers. They were active primarily in Sichuan and Yunnan and were North Americans or Europeans with one exception, Ding Wenjiang, who is examined alongside the Swede, Johan Gunnar Andersson. All were men with the exception of Hedwig Weiss, a German who travelled with her diplomat husband, Fritz, in Sichuan and photographed the Yi people of Liangshan.

    2006-01-01

    Plate-like single crystals of magnetic semiconductor FeIn 2 Se 4 were grown with a chemical vapour transport technique. The X-ray powder diffraction analyses suggest that the compound crystallize in the hexagonal structure with space group P3m1. We have performed dc magnetization measurements at different magnetic fields on the diluted magnetic semiconductor FeIn 2 Se 4 . Low field magnetizations measurements shows irreversibility in the DC magnetization, as evidenced by field cooled and zero field cooled measurements below 17 K, suggesting a spin-glass like behaviour. The high-temperature susceptibility data follow a typical Curie-Weiss law with θ=-183±2 K which suggest the presence of predominant antiferromagnetic interactions with high degree of frustration. The randomness and frustration necessary for spin-glass behaviour are explained in a manner compatible with the cation and charge ordering present in the material

    We present the magnetic properties of silica-supported metal (Fe,catalyst) nanoparticles synthesized by precipitation of metal nitrate in ammonia-based medium. Our goal is the study of possible metal-support interactions in the nanoporous catalyst. The temperature dependence of the magnetization for all samples display spin-glass like behavior below c.a. 11-12 K, with clear Curie-Weiss dependence in the high-temperature regime. Spin-glass-like behavior was inferred from dynamic AC susceptibility data after analyzing the frequency-dependence of the in-phase component {chi}'(f) by the expression W = {Delta}T{sub f}/[T{sub f} {Delta}log(f)] = 3.0 x 10{sup -3}. We found that the magnetic behavior of the catalyst is drastically affected by the existence of interactions between the metal and the support.

    de Oliveira, Mário J

    2017-01-01

    This textbook provides an exposition of equilibrium thermodynamics and its applications to several areas of physics with particular attention to phase transitions and critical phenomena. The applications include several areas of condensed matter physics and include also a chapter on thermochemistry. Phase transitions and critical phenomena are treated according to the modern development of the field, based on the ideas of universality and on the Widom scaling theory. For each topic, a mean-field or Landau theory is presented to describe qualitatively the phase transitions. These theories include the van der Waals theory of the liquid-vapor transition, the Hildebrand-Heitler theory of regular mixtures, the Griffiths-Landau theory for multicritical points in multicomponent systems, the Bragg-Williams theory of order-disorder in alloys, the Weiss theory of ferromagnetism, the Néel theory of antiferromagnetism, the Devonshire theory for ferroelectrics and Landau-de Gennes theory of liquid crystals.

    Full Text Available A linguistic analysis was performed on the Preschool Five Minute Speech Sample (PFMSS of 42 parents. PFMSS is a validated measure for Expressed Emotion (EE to assess parent-child relationship. Half of these parents (n = 21, clinical group had preschool children with early symptoms of attention deficit hyperactivity disorder (ADHD, the rest had typically developing children. Early symptoms of ADHD were identified with the Werry-Weiss Peters Rating Scale. The linguistic component of the PFMSS was analysed with keyword and linguistic pattern identification. The results of these two complementary analyses (i.e., EE and linguistic analysis provided relevant recommendations that may improve the efficacy of psychological treatment for ADHD such as parenting interventions. We discuss the practical implications of these findings.

    2006-01-01

    The authors tested a model, inspired by affective events theory (H. M. Weiss & R. Cropanzano, 1996), that examines the dynamic nature of emotions at work, work attitudes, and workplace deviance. Sixty-four employees completed daily surveys over 3 weeks, reporting their mood, job satisfaction, perceived interpersonal treatment, and deviance. Supervisors and significant others also evaluated employees' workplace deviance and trait hostility, respectively. Over half of the total variance in workplace deviance was within-individual, and this intraindividual variance was predicted by momentary hostility, interpersonal justice, and job satisfaction. Moreover, trait hostility moderated the interpersonal justice-state hostility relation such that perceived injustice was more strongly related to state hostility for individuals high in trait hostility.

    We have studied the magnetic and magneto-optical properties of CdS:Mn quantum dots in polyvinyl alcohol matrix synthesized by co-precipitation method. The size of quantum dots was estimated by means of absorption spectroscopy. The results of measurements of magnetic susceptibility as a function of temperature and spectral dependence of the Faraday rotation of CdS:Mn quantum dots / polyvinyl alcohol composites are presented. In this work magnetic susceptibility was investigated by Faraday's method at the temperatures of (78-300) K in magnetic fields of (0.05-0.8) T. The inverse magnetic susceptibility as a function of temperature follows a Curie Weiss law. Formation of ferromagnetic coupling between magnetic ions is supposed. Magneto-optical Faraday rotation has been investigated in the wavelength region (400-700) nm at temperature 300 K in a magnetic field up to 5 T. Sign of the Verdet constant is found to be negative.

    1973-04-01

    The behavior of preadolescent and adolescent boys, rated as aggressive and nonaggressive, was examined to test predictions from Bandura and Walters' social-learning theory and from Weiss and Miller's punishment model of audience-observation effects. The subjects were given a bogus motor task, actually insoluble, with help available on each trial. For half the subjects, help was given through the mediation of a social agent; for the rest, help was on a nonsocial, mechanically mediated basis. The groups for whom help was socially mediated made fewer help-seeking responses and decreased the number of such responses over successive trial blocks. The predictions from Bandura and Walters' theory were not supported, since neither age nor degree of aggressiveness had an effect on help-seeking responses. The results were, however, consistent with the punishment model of audience effects.

    2014-01-01

    Full Text Available The Ho doped BaTiO3 ceramics, with different Ho2O3 content, ranging from 0.01 to 1.0 wt % Ho, were investigated regarding their microstructural and dielectric characteristics. Doped BaTiO3 were prepared using conventional solid state reaction and sintered at 1380°C for four hours. SEM analysis of Ho/BaTiO3 doped ceramics showed that the low doped samples exhibit mainly fairly uniform and homogeneous microstructure with the grain size ranged from 20-40 μm. In the samples with the higher dopant concentration the abnormal grain growth is inhibited and the grain size ranged between 2-10 μm. Measurements of dielectric properties were carried out as a function of temperature up to 180 °C at different frequencies. The samples doped with 0.01wt % of Ho, exhibit the high value of dielectric permittivity (εr = 2160 at room temperature. A nearly flat permittivity-response was obtained in specimens with higher additive content. Using a Curie-Weiss law and modified Curie-Weiss law the Curie constant (C, Curie temperature (Tc and a critical exponent of nonlinearity (g were calculated. The Curie temperature of doped samples were ranged from 128 to 130°C. The Curie constant for all series of samples decrease with increase of dopant concentration and the lowest values were observed on samples doped with 0.01 wt % of holmium.

    We have investigated the magnetic properties of the CexY1-xPt Kondo ferromagnetic alloy system in the temperature range from 1.8 K to 320 K. The results of these investigations can be summarized as follows: dc-susceptibility can be described by the Curie-Weiss law at higher temperatures down to about 100 K, but also at low temperatures above the ferromagnetic phase transition. At higher temperatures, the extracted Curie-Weiss parameter, θp, is negative and at low temperature θC is positive. The extracted effective magnetic moment above 100 K increases with the Ce content up to almost the theoretical value of the isolated Ce3+ ion, μ = 2.54 μB, for CePt. This suggests an increase of the hybridization with decreasing Ce content, or said equivalently, it means that the increase of the Kondo interaction diminishes effective magnetic moment. These observations confirm the main conclusions inferred from an earlier transport properties investigation of this alloy system. The corresponding θC differs within 1 K from the Curie temperature, TC, which is determined by the resistivity measurements. The most intriguing result of the investigation of CexY1-xPt is the linear concentration dependence of TC vs. x and, moreover, it is the same as in CexLa1-xPt although in the former system the hybridization diminishes considerably the effective magnetic moment per Ce ion, while in the latter system, hybridization is minor and independent of x. We offer the explanations of these intriguing experimental results.

The calculated second order phase transition temperatures of the monoclinic phase were added to the existing phase diagram. The completed magnetic-structural phase diagram carries now all the information including the magnetic transition temperatures of both monoclinic and orthorhombic phases. It was also found that the magnetic transition temperature of the monoclinic phase and the first order transition temperature are interrelated. - Highlights: • Magnetocaloric Gd 5 (Si x Ge 1−x ) 4 for 0.41Weiss law and Arrott Plot technique were used to analyse M vs. H isotherms. • Second order phase transition temperatures of the monoclinic phase were estimated. • Magnetic-structural phase diagram Gd 5 (Si x Ge 1−x ) 4 for 0.41

  9. Fracture dynamics of a propagating crack in a pressurized ductile cylinder

    1977-01-01

    A suddenly-introduced axial through-crack in the wall of a pipe pressurized by hot water is allowed to propagate according to Weiss' notch-strength theory of ductile static fracture. For this somewhat ductile material of A533B steel, Weiss' criterion was extended of dynamic fracture without modification. This dynamic-fracture criterion enabled a unique comparison to be obtained for the results of ductile-fracture with those of brittle-fracture in a fracturing A533B steel pipe. Since the pipe cross-sectional area is likely to increase with large flap motions under ductile tearing, a large deformation-shell-finite-difference-dynamic-code which includes rotary inertia was used in this analysis. The uniaxial-stress-strain curve of A533B steel was approximated by a bilinear stress-strain where Von-Misses yield criterion and associated flow rule were used in the elastic-plastic analysis. The fluid pressure was assumed constant and thus pipe flaps are only lightly loaded by pressure in this analysis. In previous publications, the authors have compared their preliminary results for the shell motion obtained through their model for a fracturing pipe with those of Kanninen, et al., and Freund, et al., to evaluate the effects of pressure loading on the crack flaps and the differences between small and large deflection results. In this paper, the differences in crack-propagation behavior of a fracturing pipe composed of the same A533B but subjected to a brittle or a ductile-fracture criterion are discussed. An important conclusion in fracture dynamics derived from analyses is that a smoothly-varying crack velocity will require a non-unique crack-velocity-versus-dynamic-fracture-parameter-relation while a unique and smoothly-varying crack-velocity-versus-dynamic-fracture-parameter-relation will demand an intermittently-propagating crack

    The results of magnetic susceptibility, χ(T), magnetization, σ(μ 0 H), and specific heat, C P (T), for GdCu 4 Au are presented. The room temperature powder X-ray diffraction studies indicate a cubic MgCu 4 Sn – type crystal structure with space group F4-bar 3m (No.216). The low field dc χ(T) data shows an antiferromagnetic – like (AFM) anomaly associated with a Néel temperature T N = 10.8 K for GdCu 4 Au. In the paramagnetic region above T N , χ(T) data follows the Curies – Weiss law with an effective magnetic moment μ eff = 7.444(1) μ B and paramagnetic Weiss temperature θ P = -15.01(2) K. The experimental value of is close to the calculated value of 7.94 μ B expected for the free Gd 3+ -ion. The field-cooled (FC) and zero-field-cooled (ZFC) χ(T) data provide evidence for the formation of spin-glass state with a freezing temperature T f = 15 K. σ(μ 0 H) measured in the ordering region (below TN) shows that GdCu 4 Au undergoes metamagnetic transition above 0.7 T, characterized by a slight upward curvature above this field. Measurement of σ(μ 0 H) in the paramagnetic regions show a linear behaviour up to 0.7 T and a downward curvature at high fields. C P (T) data shows an AFM – like phase transition at T N = 10.4 K close to the phase transition observed in χ(T) results. The 4f-electron entropy reaches the value of Rln2 close to T N at 9.02 K and reaches the value of Rln(2J + 1) at T = 180 K

  11. Data science implications in diamond formation and craton evolution

    Science.gov (United States)

    Pan, F.; Huang, F.; Fox, P. A.

    2017-12-01

    Diamonds are so-called "messengers" from the deep Earth. Fluid and mineral inclusions in diamonds could reflect the compositions of fluids/melts and wall-rocks in which diamond formed. Recently many diamond samples are examined to study the water content in the mantle transition zone1, the mechanism of diamond formation2 and the mantle evolution history3. However, most of the studies can only explain local activities. Therefore, an overall project of data grouping, comparison and correlation is needed, but limited progress has been made due to a lack of benchmark datasets on diamond formation and effective computing algorithms. In this study, we start by proposing the very first complete and easily-accessible dataset on mineral and fluid inclusions in diamonds. We rescue, collect and organize the data available from papers, journals and other publications resources ([2-4] and more), and then apply several state-of-the-art machine learning methods to tackle this earth science problem by clustering diamond formation process into distinct groups primarily based on the compositions, the formation temperature and pressure, the age and so on. Our ongoing work includes further data exploration and training existing models. Our preliminary results show that diamonds formed from older cratons usually have higher formation temperature. Also peridotitic diamonds take a much larger population than the ecologitic ones. More details are being discovered when we finish constructing the database and training our model. We expect the result to demonstrate the advantages of using machine learning and data science in earth science research problems. Our methodology for knowledge discovery are very general and can be broadly applied to other earth science research problems under the same framework.[1] Pearson et al, Nature (2014); [2] Tomlinson et al, EPSL (2006); [3] Weiss et al, Nature (2016); [4] Stachel and Harris, Ore Geology Reviews (2008); Weiss et al, EPSL (2013)

    In order to study Kondo ferromagnetism, particularly of the CePt compound, we investigate the magnetic properties of the Ce{sub x}La{sub 1−x}Pt alloy system in the temperature range from 1.8 K to 320 K. The results of these investigations can be summarized as follows: dc-susceptibility can be described by the Curie–Weiss law at higher temperatures down to about 100 K, but also at the low temperatures above the phase transition. At higher temperatures, the extracted Curie–Weiss constant, θ{sub p}, is negative in contrast to the low temperatures, where θ{sub C} is positive. The extracted effective magnetic moment from the higher temperatures is the same for all the alloys and is close to the theoretical value of the isolated Ce{sup 3+} ion, μ=2.54 μ{sub B}, indicating the hybridization is weak and, and consequently, Kondo interaction is weak. These observations confirm the main important conclusions inferred from an earlier transport properties investigation of this alloy system. The Curie temperature extracted by various approaches was compared to the extraction from the ac-susceptibility measurements. We show that its concentration dependence is not consistent with Doniach's diagram. Hence, RKKY interaction is not responsible for the ferromagnetism in this alloy system. - Highlights: • We have found that for Ce{sub x}La{sub 1−x}Pt the temperature of the ferromagnetic transition linearly depends on x. • The Kondo temperature is independent of x. • Hence, RKKY interaction is not responsible for the ferromagnetism. • The lattice parameters show that direct exchange interaction is possible. • We expect that the investigations of Ce{sub x}Y{sub 1−x} will confirm our conclusions.

    Co doped TiO 2 nanoparticles have been synthesized by a simple sol-gel route taking 7.5, 9.5 and 10.5 mol% of cobalt concentration. Formation of nanoparticles is confirmed by XRD and TEM. Increase in d-spacing occurs for (0 0 4) and (2 0 0) peak with increase in impurity content. Valence states of Co and its presence in the doped material is confirmed by XPS and EDX. The entire vacuum annealed samples show weak ferromagnetism. Increased magnetization is found for 9.5 mol% but this value again decreases for 10.5 mol% due to antiferromagnetic interactions. A blocking temperature of 37.9 K is obtained, which shows shifting to high temperature as the dopant concentration is increased. The air annealed sample shows only paramagnetic behavior. Temperature dependent magnetic measurements for the air annealed sample shows antiferromagnetic behavior with a Curie-Weiss temperature of -16 K. Here we report that oxygen vacancy and cobalt aggregates are a key factor for inducing ferromagnetism-superparamagnetism in the vacuum annealed sample. Appearance of negative Curie-Weiss temperature reveals the presence of antiferromagnetic Co 3 O 4 , which is the oxidation result of metallic Co or cobalt clusters present on the host TiO 2 . - Research highlights: → Oxygen vacancy induces ferromagnetism in cobalt doped anatase TiO2 nanoparticles. → On air annealing the sample loses ferromagnetism giving rise to paramagnetism. → Saturation magnetization decreases at higher doping concentration. → Blocking of magnetic moment occurs due to the presence of cobalt clusters.

    We study the problem of predictability, or "nature vs nurture," in several disordered Ising spin systems evolving at zero temperature from a random initial state: How much does the final state depend on the information contained in the initial state, and how much depends on the detailed history of the system? Our numerical studies of the "dynamical order parameter" in Edwards-Anderson Ising spin glasses and random ferromagnets indicate that the influence of the initial state decays as dimension increases. Similarly, this same order parameter for the Sherrington-Kirkpatrick infinite-range spin glass indicates that this information decays as the number of spins increases. Based on these results, we conjecture that the influence of the initial state on the final state decays to zero in finite-dimensional random-bond spin systems as dimension goes to infinity, regardless of the presence of frustration. We also study the rate at which spins "freeze out" to a final state as a function of dimensionality and number of spins; here the results indicate that the number of "active" spins at long times increases with dimension (for short-range systems) or number of spins (for infinite-range systems). We provide theoretical arguments to support these conjectures, and also study analytically several mean-field models: the random energy model, the uniform Curie-Weiss ferromagnet, and the disordered Curie-Weiss ferromagnet. We find that for these models, the information contained in the initial state does not decay in the thermodynamic limit-in fact, it fully determines the final state. Unlike in short-range models, the presence of frustration in mean-field models dramatically alters the dynamical behavior with respect to the issue of predictability.

    We consider a collection of Curie–Weiss (CW) spin systems, possibly with a random field, each of which is placed along the positions of a one-dimensional chain. The CW systems are coupled together by a Kac-type interaction in the longitudinal direction of the chain and by an infinite-range interaction in the direction transverse to the chain. Our motivations for studying this model come from recent findings in the theory of error-correcting codes based on spatially coupled graphs. We find that, although much simpler than the codes, the model studied here already displays similar behavior. We are interested in the van der Waals curve in a regime where the size of each Curie–Weiss model tends to infinity, and the length of the chain and range of the Kac interaction are large but finite. Below the critical temperature, and with appropriate boundary conditions, there appears a series of equilibrium states representing kink-like interfaces between the two equilibrium states of the individual system. The van der Waals curve oscillates periodically around the Maxwell plateau. These oscillations have a period inversely proportional to the chain length and an amplitude exponentially small in the range of the interaction; in other words, the spinodal points of the chain model lie exponentially close to the phase transition threshold. The amplitude of the oscillations is closely related to a Peierls–Nabarro free energy barrier for the motion of the kink along the chain. Analogies to similar phenomena and their possible algorithmic significance for graphical models of interest in coding theory and theoretical computer science are pointed out

    Magnetization data on the bulk ZnFe{sub 2}O{sub 4} antiferromagnetic compound (T{sub N}≈10 K) obtained via solid state reaction at different synthesis temperatures show one weak ferromagnetic component at room temperature. We have related it with the cationic disorder effect present on spinel structure of our bulk samples which comes from the magnetic interaction between iron ions sit on both octahedral and tetrahedral sites. The magnetization measurements show to all samples a clear peak around 10 K consistent with the antiferromagnetic phase transition. On the other hand, after extracted the paramagnetic component, the hysteresis loops measured at room temperature display one weak ferromagnetic component. Once the T-dependence of magnetization does not fit to a Curie–Weiss law to temperatures well above the magnetic transition we have used a combination of the Curie–Weiss law (paramagnetic spins) and a typical temperature dependence of M{sub 0}, M{sub 0}(T)=M{sub 0}(0)[1−(T/T{sub C}){sup 2}]{sup 0.5} (ordered ferromagnetic spins). We note an increase of the M{sub 0}(0) as function of the synthesis temperature. This reinforce our supposition of a cationic disorder effect driving the system to present two kinds of magnetic interactions between iron ions on A and B sites. - Highlights: • Study of the cationic disorder at bulk ZnFe{sub 2}O{sub 4} compound. • Structural and magnetization characterization. • The observation of two magnetic phases.

    Zn{sub 1−x}Co{sub x}O (0 < x < 0.146) conductive thin films have been deposited by reactive magnetron sputtering of metallic Zn and Co targets at high pressure and temperature. The structural properties have been investigated by using X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). It has been observed that all as-deposited films are crystallized in pure hcp ZnO structure and neither traces of metallic nor oxide Co-rich clusters were detected. The average grain size estimated from full width at half maximum of XRD results varied between 65 and 83 nm. XPS analyses exhibit that Co ions are successfully entered into ZnO lattice as Co{sup +2}. The electrical properties including conductivity, carrier density and carrier mobility were determined by Hall effect measurements in a temperature range from 300 K to 475 K. The conductivity of the films decreases from σ{sub 300K} = 2.2 × 10{sup 4} to 2.3 × 10{sup −1} Sm{sup −1} as the Co content changes from 0 to 0.146. Magnetic measurements reveal the absence of ferromagnetism even at 3 K and a paramagnetic Curie–Weiss behavior associated to magnetic clusters. - Highlights: • Zn{sub 1−x}Co{sub x}O conductive thin films were synthesized by reactive magnetron sputtering. • Structural characterization exhibited the absence of Co clusters or secondary phases. • The film conductivity decreased with increasing of Co concentration. • No ferromagnetism was observed in all Co doped ZnO samples. • Magnetic properties are described by a Curie–Weiss behavior associated to clusters.

    We present {sup 75}As Nuclear Magnetic Resonance (NMR) measurements on the iron-based superconductor LaO{sub 1-x}F{sub x}FeAs with 0 {<=} x {<=} 0.1, covering a broad range of the phase diagram from magnetically-ordered to optimally-doped superconducting samples. For underdoped samples (x=0.05,x=0.075) the {sup 75}As NMR spin-lattice relaxation rate (T{sub 1}T){sup -1} shows a Curie-Weiss-like increase at intermediate temperatures, indicating the slowing down of spin fluctuations. However, a simple Curie-Weiss fit fails to describe (T{sub 1}T){sup -1}(T) above 250 K and the occurrence of a peak in (T{sub 1}T){sup -1} slightly above T{sub c}. Instead, the data can be well described by considering a BPP-model for fluctuating magnetic fields in combination with a doping-independent linear temperature dependence at high temperature. At optimal doping (x=0.1) spin fluctuations are suppressed and only the linear contribution to (T{sub 1}T){sup -1} is left. This stands in contrast to other pnictides, such as Ba(Fe{sub 1-x}Co{sub x}As){sub 2} and Ba(FeAs{sub 1-x}P{sub x}){sub 2}. Our analysis is consistent with charge carrier localization in underdoped LaO{sub 1-x}F{sub x}FeAs as seen by means of resistivity measurements.

    We have performed 75As NMR measurements on single crystals to investigate the nematic behavior via the in-plane anisotropy of the electronic state at the As site far from Co impurities in the representative iron arsenides Ba (Fe1-xCox) 2As2 . From the analysis of the angular dependence of the NMR satellites in the c plane using the binominal distribution, we find that there is the in-plane fourfold symmetry breaking, namely, the orthorhombic-type anisotropy in the electric field gradient (EFG) at the As site with no Co atom at the nearest neighboring Fe sites even in the tetragonal phase of both BaFe2As2 and Ba (Fe1-xCox) 2As2(x ≠0 ) . The NMR spectrum in the antiferromagnetically ordered state of BaFe2As2 is shown not to support a nanotwin model on the basis of the nematic order proposed from the pair-distribution analysis of neutron scattering data. Based on results of the x and temperature T dependences of the in-plane anisotropy in the wide x and T ranges, the symmetry breaking is concluded to come from the local orthorhombic domains induced by disorder such as Co impurities or lattice imperfections. Furthermore, we find that the asymmetry parameter of EFG η obeys the Curie-Weiss law which may be governed by nematic susceptibility, and the Weiss temperature becomes zero at xc˜0.05 in Ba (Fe1-xCox) 2As2 .

    A powdered cerous magnesium nitrate (CMN) temperature scale has been developed in the 0.016 to 3.8 K region which represents an interpolation between the 3 He/ 4 He (T 62 /T 58 ) vapor pressure scale and absolute temperatures in the millikelvin region as determined with a 60 Co in hcp Co nuclear orientation thermometer (NOT). Both ac and dc susceptibility thermometers were used in these experiments. The ac susceptibility of a 13 mg CMN-oil slurry was measured with a mutual inductance bridge employing a SQUID null detector while the dc susceptibility of a 3 mg slurry was measured with a SQUID/flux transformer combination. To check the internal consistency of the NOT, γ-ray intensities were measured both parallel and perpendicular to the Co crystal c-axis. The independent temperatures determined in this fashion were found to agree to within experimental error. For the CMN thermometers employed in these experiments, the susceptibility was found to obey a Curie-Weiss law with a Weiss constant of Δ = 1.05 +- 0.1 mK. The powdered CMN scale in the 0.05 to 1.0 K region was transferred to two germanium resistance thermometers for use in low-temperature specific heat measurements. The integrity of the scale was checked by examining the temperature dependence of the specific heat of high purity copper in the 0.1 to 1 K region. In more recent experiments in this laboratory, the scale was also checked by a comparison with the National Bureau of Standards cryogenic temperature scale (NBS-CTS-1). The agreement between the two scales in the 99 to 206 mK region was found to be on the order of the stated accuracy of the NBS scale
