Critical behavior at edge singularities in one dimensional spin models

In ferromagnetic spin models above the critical temperature ($T > T_{cr}$) the partition function zeros accumulate at complex values of the magnetic field ($H_E$) with a universal behavior for the density of zeros \rho (H) \sim | H - H_E |^{\sg}. The critical exponent \sg is believed to be universal at each space dimension and it is related to the magnetic scaling exponent $y_h$ via \sg = (d-y_h)/y_h. In two dimensions we have y_h=12/5 (\sg = -1/6) while y_h=2 (\sg=-1/2) in $d=1$. For the one dimensional Blume-Capel and Blume-Emery-Griffiths models we show here, for different temperatures, that a new value y_h=3 (\sg =-2/3) can emerge if we have a triple degeneracy of the transfer matrix eigenvalues.Comment: to appear in Phys.

Caracterização Geoquímica de Jazigos Filonianos de Pb-Zn-(Ag) através do Estudo Estatístico dos Teores em Elementos Menores em Sulfuretos

Sulfides from Portuguese Vein-type Pb-Zn-(Ag) deposits were analysed with electronic microprobe. The results obtained for several minor elements present in galena and sphalerite were then statistically studied using principal components analysis (PCA). We intend to contribute to the geochemical characterization of these deposits through their contents in the minor elements. We hope to distinguish different subtypes of vein Pb-Zn-(Ag) deposits through the statistical analysis of minor elements present in sulfide

Patients with cancer: social representations in nursing

The meaning attributed to cancer, when passing the patient-family boundary is, in some degree, also shared between health professionals, which can have effect on the professionals’ performance and influence the opinions of users about health services. The focus of this work is the analysis of social representations about patients with cancer, in a population of nurse students, professional nurses working with cancer patients, and professional nurses not working with cancer patients, of both sexes. Our main goal is to know their conceptions towards oncologic patients. The methodological option was the social representations theory. The data was retrieved by questionnaire using the free word association technique. Several Factorial Correspondence Analysis where made to identify the different dimensions (or dependent variables). In general, all professional groups represent oncologic patients by their physical alterations. Nurse students decipher cancer in a distant perspective, as the unknown and something that causes discomfort and eventually… death. In fact, patients with cancer are strongly associated to situations of pain, involving suffering, and death. Women show a more positive perception of cancer, supported in treatment and hoping for a healing possibility. Men demonstrate a greater difficulty in dissociating the patients with cancer of people who soon will die. There is still a long way to walk before cancer patients are no longer associated to a death sign.info:eu-repo/semantics/publishedVersio

Capacitive Coupling of Two Transmission Line Resonators Mediated by the Phonon Number of a Nanoelectromechanical Oscillator

Detection of quantum features in mechanical systems at the nanoscale constitutes a challenging task, given the weak interaction with other elements and the available technics. Here we describe how the interaction between two monomodal transmission-line resonators (TLRs) mediated by vibrations of a nano-electromechanical oscillator can be described. This scheme is then employed for quantum non-demolition detection of the number of phonons in the nano-electromechanical oscillator through a direct current measurement in the output of one of the TLRs. For that to be possible an undepleted field inside one of the TLR works as a amplifier for the interaction between the mechanical resonator and the remaining TLR. We also show how how the non-classical nature of this system can be used for generation of tripartite entanglement and conditioned mechanical coherent superposition states, which may be further explored for detection processes.Comment: 6 pages, 5 figure

Nova praga exótica no ecossistema florestal.

O país está convivendo desde de junho de 2003 com mais uma séria praga de florestas de eucalipto, o psilídeode- concha, Glycaspis brimblecombei (Hemiptera: Psyllidae). Este inseto, de tamanho reduzido, é semelhante a uma cigarrinha que suga a seiva das folhas novas das árvores. A praga tem provocado danos às florestas de eucaliptos, e atualmente se encontra distribuída em mais de 140 municípios do Estado de São Paulo, em pelo menos 20 municípios de Minas Gerais, um de Goiás, dois de Mato Grosso do Sul e seis do Paraná.bitstream/CNPMA/5837/1/comunicado_18.pd

O protocolo de pesquisa após a aprovação pelo sistema CEP/CONEP: explorando o caminho das competências e responsabilidades do CEP/UNICAMP

As normas vigentes do Sistema CEP/CONEP são: Resolução CNS/MS 466/12 e, aos estudos das CHS, a Resolução 510/2016. Os CEPs têm como competência a proteção aos participantes de pesquisa. Os protocolos de pesquisa são submetidos aos CEPs e CONEP, se necessário, através da Plataforma Brasil. Buscou investigar se após a aprovação dos protocolos no CEP/Unicamp, eles consideraram aos aspectos éticos. O estudo teve como objetivos relacionar semelhanças e diferenças de projetos aceitos pelo CEP/Unicamp na Plataforma Brasil frente as suas publicações de bancos de dados bibliográficos para delinear as competências e responsabilidades do CEP/Unicamp após aprovação dos protocolos. Métodos: Entre 01/03/2012 até 28/02/2013, foram aceitos 876 protocolos de pesquisa extraídos da Plataforma Brasil que, ao aplicar os critérios de inclusão e exclusão e, posteriormente, pesquisar nas seis bases bibliográficas (Google, Google Acadêmico, Repositório da Unicamp, WoS, BVS, SciELO), estratificou-se para 181 protocolos aceitos e aprovados pela Plataforma Brasil que, obteve destes, 246 publicações
