Measurement of differential cross sections for the production of a pair of isolated photons in pp collisions at root s=7TeV

A measurement of differential cross sections for the production of a pair of isolated photons in proton-proton collisions at root s = 7 TeV is presented. The data sample corresponds to an integrated luminosity of 5.0 fb(-1) collected with the CMS detector. A data-driven isolation template method is used to extract the prompt diphoton yield. The measured cross section for two isolated photons, with transverse energy above 40 and 25 GeV respectively, in the pseudorapidity range vertical bar eta vertical bar < 2.5, vertical bar eta vertical bar (sic) [1.44, 1.57] and with an angular separation Delta R > 0.45, is 17.2 +/-0.2 (stat) +/-1.9 (syst) +/- 0.4 (lumi) pb. Differential cross sections are measured as a function of the diphoton invariant mass, the diphoton transverse momentum, the azimuthal angle difference between the two photons, and the cosine of the polar angle in the Collins-Soper reference frame of the diphoton system. The results are compared to theoretical predictions at leading, next-to-leading, and next-to-next-to-leading order in quantum chromodynamics.

Magnetic-size effects in ultrathin layers

We study N-layer samples (N ≤ 10) for the Heisenberg model, with ferro- and antiferromagnetic exchange couplings, using a modified version of the Onsager reaction field approximation. The present scheme includes short-range spin-spin correlations, and allows for layer-dependent order parameters when free surface boundary conditions are imposed. The limits N = 1 (two dimensions) and N → ∞ (three dimensions) can be solved analytically, while systems with several layers have to be numerically calculated. We found no indication of a phase transition at finite temperature up to the sizes investigated (N = 10), the layered systems behaving essentially as two-dimensional. A phase transition is only obtained for the three-dimensional limit. © 1993.

Exercício físico aeróbio para promoção da saúde de pacientes com doença de Alzheimer

Introdução: Sabe-se que a prática regular e sistematizada de atividade física é uma eficiente estratégia para evitar a deterioração cognitiva e funcional associada à Doença de Alzheimer (DA), uma doença progressiva, degenerativa e irreversível. Na população idosa os benefícios observados com a prática de exercícios físicos aeróbios já se encontram bem estabelecidos, contudo pouco ainda se sabe quanto à prática deste tipo de atividade em pacientes com DA. Em estudos realizados com modelo animal pode-se observar que o exercício físico aeróbio foi capaz de reduzir os níveis da proteína β-amilóide, sendo esta uma proteína característica da DA, que provoca degeneração no cérebro dos pacientes. A redução dos marcadores característicos da doença pode promover benefícios para os pacientes. Objetivos: Promover a prática de exercícios físicos para promoção/manutenção da saúde de pacientes com DA. Métodos: O estudo está sendo desenvolvido no PRO-CDA (Programa de Cinesioterapia Funcional e Cognitiva em Idosos com Doença de Alzheimer), projeto de Extensão do Departamento de Educação Física da UNESP – Campus Rio Claro, vinculado ao Núcleo Local UNESP-UNATI. O projeto atende atualmente 34 pacientes, divididos em dois grupos: Grupo Convívio Social e Grupo Exercício. O primeiro tem por objetivo desenvolver a adaptação do paciente à rotina do projeto. Já o segundo grupo busca promover os benefícios observados com a prática de atividade física nos pacientes participantes. Ambos os grupos realizam atividades três vezes na semana, com 60 minutos de duração cada sessão. O projeto conta com a participação de alunos de graduação, dos cursos de educação física, pedagogia e biologia, bem como discentes de pós-graduação da UNESP, além de aprimorandos graduandos e graduados dos cursos de educação física, fisioterapia, gerontologia e psicologia de outras universidades, que atuam sob a coordenação de docentes vinculados ao Departamento de Educação Física e de Educação. Resultados: Por se tratar de um protocolo de intervenção motora iniciado recentemente, o presente estudo ainda não apresenta resultados. Contudo protocolos de atividade física desenvolvidos anteriormente no PRO-CDA evidenciam melhora na realização de atividades de vida diária, manutenção das funções cognitivas, qualidade de vida e redução dos distúrbios de comportamento nos pacientes participantes. Espera-se que o protocolo de exercício físico aeróbio possa influenciar positivamente os participantes do projeto, com melhora na qualidade de vida, tanto de pacientes como de cuidadores, redução de sintomas depressivos, melhora dos distúrbios do sono e da condição motora.

Resultados da atenção farmacêutica no Brasil: uma revisão

The practice of pharmaceutical care (PC) is recent in Brazil and little is known about its impact on the health system or patients. The aim of this review was thus to identify the clinical, humanistic and economic outcomes achieved by the practice of PC in Brazil. In order to assess those outcomes, data published in studies from 1997 to 2011 were collected from Lilacs and MEDLINE databases, using the technique of content analysis. Original studies on PC that included pharmacotherapeutic follow-up were considered eligible for this descriptive review. A total of 306 articles were identified through the chosen descriptors. Of those, ten studies were eligible for this review and only two did not report significant results. The others reported increased adherence to pharmacotherapy, resolution of pharmacotherapeutic issues and control of clinical parameters of diseases (such as maintenance or reduction of blood pressure, reduction in HIV viral load and increase in lymphocyte count), promoting improvements in the general state of health and behavioral changes. However, economic impact was not assessed in any article analyzed, nor was a direct measurement of life quality performed. Although there are few studies on the outcomes of pharmaceutical care services in Brazil, it is demonstrated in this review that positive results were obtained when the pharmacist acted as a provider of optimized pharmacotherapy. This may be considered a result of the actions that followed the Brazilian Pharmaceutical Care Consensus of 2002, such as the restructuring of the curricular basis of pharmacy courses. From this point on, Brazilian researchers and pharmacists should think of a strategy to expand the offer of pharmaceutical care beyond academia and reach people in general who need this type of health care.

The aim of this study was to investigate the development of specific domains of Numerical Cognition (Number Sense – NS, Number Comprehension – NC, Number Production – NP, and Calculation – CA) in Brazilian children with Specific Learning Disorders. The study included 72 children (36 boys), from 9-to 10-years-old, enrolled in 4th and 5th years of elementary school of public schools at countryside of Sao Paulo State, Brazil. They were divided into three groups: control (CT, N = 42), Developmental Dyslexia (DL, N = 11) and Developmental Dyscalculia combined with dyslexia (DDc, N = 19). All participants had intellectual level within the normal range, however, children from the last two groups had Learning Disorders classified by School Achievement Test - TDE (Stein, 1994) and DDc children received necessarily classification as 'inferior' in Arithmetic Test of TDE. The children did not differ in NS. DL and DDc children showed slight deficits in NC. However, DDc children had moderate in NP and mild to moderate deficits in CA, which indicates a more generalized impairment in Numerical Cognition. Furthermore, DDc children showed discrepancy in Numerical Cognition performance when compared to the other groups. Thus, children with Learning Disorders showed different performances in Numerical Cognition, although both groups had preserved SN, DDc children showed higher deficits and discrepancy in relation DL and typically developing children.
