Exact analytical solution to the relativistic Klein-Gordon equation with non-central equal scalar and vector potentials

We present an alternative and simple method for the exact solution of the Klein-Gordon equation in the presence of the non-central equal scalar and vector potentials by using Nikiforov-Uvarov (NU) method. The exact bound state energy eigenvalues and corresponding eigenfunctions are obtained for a particle bound in a potential of $V(r,\theta) = \frac{\alpha}{r} + \frac{\beta}{r^2\sin ^2\theta} + \gamma \frac{\cos \theta}{r^2\sin ^2\theta}$ type.Comment: 12 pages, accepted for publication in Journal of Mathematical Physic

Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores

A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do município de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola não vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, não entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importância de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vínculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la Educació

Correlations among enthesitis, clinical, radiographic and quality of life parameters in patients with ankylosing spondylitis

WOS: 000338636500018PubMed ID: 24252034Objectives. To investigate the relationship between enthesitis and disease activity, functional status, fatigue, joint mobility, radiological damage, laboratory parameter and quality of life in patients with ankylosing spondylitis (AS). Methods. A total of 421 patients with AS (323 male and 98 female) who were included in the Turkish League Against Rheumatism Registry were enrolled in the study. The Bath AS Disease Activity Index (BASDAI), fatigue, the Bath AS Functional Index (BASFI), the Bath AS Metrology Index (BASMI), the Maastricht AS Enthesitis Score (MASES), AS quality of life (ASQoL), the Bath AS Radiology Index (BASRI) and erythrocyte sedimentation rate (ESR) were evaluated. Results. Enthesitis was detected in 27.3% of patients. There were positive correlations between MASES and BASDAI, BASFI and fatigue (p < 0.05). MASES was not correlated with BASRI, BASMI, ASQoL and ESR. The mean MASES score was 1.1 +/- 2.4. The most frequent regions of enthesopathies were right iliac crest, spinous process of L5 and proximal to the insertion of left achilles tendon, respectively. Conclusions. Enthesitis was found to be associated with higher disease activity, higher fatigue, worse functional status and lower disease duration. As enthesitis was correlated with BASDAI, we conclude that enthesitis can reflect the disease activity in patients with AS.Pfizer CompanyThe authors express their gratitude to all members of the TRASD-IP AS Study group for their cooperation and to Pfizer Company for the registry sponsorship

Characteristics of Patients With Rheumatoid Arthritis in Turkey: Results From the Turkish League Against Rheumatism Rheumatoid Arthritis Registry

WOS: 000352060500003Objectives: This study investigates the demographic and clinical characteristics of patients with rheumatoid arthritis (RA) in Turkey, and attempts to identify strategies for the prevention, treatment, and support of RA. Patients and methods: A total of 2,359 patients (1,966 females, 393 males; mean age 51.6 +/- 12.5 years; range 18 to 75 years) with RA from 36 centers across Turkey, who were recorded in the Turkish League Against Rheumatism (TLAR) RA Registry between September 2007 and March 2011, were evaluated. Patients' demographic and clinical data were recorded. Disease activity, functional status, and radiographic damage were measured using the Disease Activity Score 28, the Health Assessment Questionnaire, and van der Heijde modified Sharp scoring method. Results: The mean duration of academic education received was 5.2 +/- 3.8 years, and 74.6% of the patients were homemakers. Non-biological disease-modifying anti-rheumatic drugs were used by 91.0% of the patients, while 10.2% used biological disease-modifying anti-rheumatic drugs. The mean Disease Activity Score 28, Health Assessment Questionnaire, and Sharp scores were 4.0 +/- 1.4, 0.38 +/- 0.37, and 31.2 +/- 57.1, respectively. Of the patients, 17.8% were in remission and 14.1% had low disease activity rates, while 42.7% and 25.5% had moderate and high disease activity rates. Conclusion: The majority of patients with RA in Turkey are middle-aged homemakers. Despite the high rates of disease-modifying anti-rheumatic drugs use, the majority of patients had moderate and high disease activity. These findings indicate that treatment needs of RA patients are not met sufficiently.Wyeth/Pfizer CompanyWyethThe authors express their gratitude to all members of TLAR RA Study Group for their cooperation and to Wyeth/Pfizer Company for the sponsorship

Search for Pair Production of Second-Generation Scalar Leptoquarks in pp Collisions at sqrt(s) = 7 TeV

A search for pair production of second-generation scalar leptoquarks in the final state with two muons and two jets is performed using proton-proton collision data at sqrt(s) = 7 TeV collected by the CMS detector at the LHC. The data sample used corresponds to an integrated luminosity of 34 inverse picobarns. The number of observed events is in good agreement with the predictions from the standard model processes. An upper limit is set on the second-generation leptoquark cross section times beta^2 as a function of the leptoquark mass, and leptoquarks with masses below 394 GeV are excluded at a 95% confidence level for beta = 1, where beta is the leptoquark branching fraction into a muon and a quark. These limits are the most stringent to date
