Stress, burnout and coping in health professionals: a literature review
Context: Stress is a phenomenon inherent to life and it becomes inevitable, particularly in a professional context, having consequences on life quality. This is a disorder that affecting several people worldwide, namely health professionals, and is originated by various factors.
Objective: The aims of this review article are studying, in the stress and burnout in health professionals in order to clarify the definition, identify the possible causes, related factors and identify the coping strategies.
Methods: This review article was performed through data bases such as b-on, PubMed and books. It was used articles in Portuguese, English and Spanish and that corresponde to established descriptors.
Results: Stress affects individuals from any age and professional area. When is caused by work complications is called of occupational stress. This phenomenon resultes of the action of an agent stressor that can be physical, social or even psychological. Other phenomenon is Burnout Syndrome, which is characterized by emotional exhaustion, lack of professional accomplishment and depersonalization. To mitigate the effects of stress, there are specific mechanisms of coping.
Conclusion: Stress and burnout are quite prevalent phenomena among health professionals. As these professionals have a fundamental role in patient care it is extremely important that they feel well physically and psychologically, as to fulfill its functions well as caregivers. In this way, it becomes important to act in the relationship between the individual and the problem, improving the skills of encouraging to use his social and personal resources to obtain control over the circumstance inducer of stress.info:eu-repo/semantics/publishedVersio
Bifurcation analysis of the twist-Freedericksz transition in a nematic liquid-crystal cell with pre-twist boundary conditions
Motivated by a recent investigation of Millar and McKay [Mol. Cryst. Liq. Cryst., 435, 277/[937]-286/[946] (2005)], we study the magnetic field twist-Fr´eedericksz transition for a nematic liquid crystal of positive diamagnetic anisotropy with strong anchoring and pre- twist boundary conditions. Despite the pre-twist, the system still possesses Z2 symmetry and a symmetry-breaking pitchfork bifurcation, which occurs at a critical magnetic-field strength that, as we prove, is above the threshold for the classical twist-Fr´eedericksz tran- sition (which has no pre-twist). It was observed numerically by Millar and McKay that this instability occurs precisely at the point at which the ground-state solution loses its monotonicity (with respect to the position coordinate across the cell gap). We explain this surprising observation using a rigorous phase-space analysis
Improving the Knowledge on Seismogenic Sources in the Lower Tagus Valley for Seismic Hazard Purposes
The Lower Tagus Valley, that includes the metropolitan area of Lisbon, has been struck by several earthquakes which produced significant material damage and loss of lives. Their exact location remains unknown. Our goal is to shed some light into the seismogenic sources in the area using seismic reflection and geological data. In areas with no seismic coverage, potential-field data interpretation was carried out. Seismicity was overlaid to the potential seismogenic structures and high-resolution data was acquired in order to confirm which structures have been active into the Quaternary. Three major fault-zones affecting the Neogene were identified: V. F. Xira, Samora-Alcochete and Pinhal Novo. For the first fault, strong evidences suggest it is active. The other two fault-zones and other structures previously unknown can be correlated with several epicentres. Empirical relationships between maximum moment magnitude and fault area indicate that MW > 6.5 earthquakes can be expected for the larger structures
Contributions of neuromarketing to design
The reported study aims to assign different perspectives for reflection; to consider how neuromarketing can assist in understanding consumer behavior, intending to investigate the best way to develop products and improve communication through neuroscience. The systematic literature review referred here applies as a scientific method of research and analysis in a specific area of science. Following the PRISMA guidelines (2009), the research was carried out in March and April 2020, in seven electronic databases for the inclusion of quantitative, qualitative, or mixed studies published in Portuguese or English, master's or doctoral theses and research reports that focused in neuromarketing. One hundred and fifty studies were conducted, 20 of which, met the inclusion criteria. 1st filter: title, abstract, keywords and references; 2nd filter: introduction and conclusion of studies; 3rd filter: full reading of the studies (Liberati et al., 2009).This work is financed by portuguese national funds through FCT - Fundação para a Ciência e Tecnologia,

Carbon coating of the SPS dipole chambers
The Electron Multipacting (EM) phenomenon is a limiting factor for the
achievement of high luminosity in accelerators for positively charged particles
and for the performance of RF devices. At CERN, the Super Proton Synchrotron
(SPS) must be upgraded in order to feed the Large Hadron Collider (LHC) with 25
ns bunch spaced beams. At such small bunch spacing, EM may limit the
performance of the SPS and consequently that of the LHC. To mitigate this
phenomenon CERN is developing a carbon thin film coating with low Secondary
Electron Yield (SEY) to coat the internal walls of the SPS dipoles beam pipes.
This paper presents the progresses in the coating technology, the performance
of the carbon coatings and the strategy for a large scale production.Comment: 7 pages, contribution to the Joint INFN-CERN-EuCARD-AccNet Workshop

Shame, Self-Criticism, Perfectionistic Self-Presentation and Depression in Eating Disorders
Costa, J., Marôco, J., Pinto-Gouveia, J., & Ferreira, C. (2016). Shame, Self-Criticism, Perfectionistic Self-Presentation and Depression in Eating Disorders. International Journal of Psychology and Psychological Therapy, 16(3), 317-328. http://www.ijpsy.com/volumen16/num3/449.htmlThe complexity of eating disorder (ED) manifestations has increased the interest in understanding the mechanisms underlying the eating psychopathology and it is now widely accepted that there are multiple risk pathways for both the development and maintenance of eating psychopathology. This study examined the association between external shame and depression. We also investigated the possible mediation effect of self-criticism in the relation between shame and depression. Further to that, the current cross-sectional study inspected whether this mediation exists for different conditional values of perfectionistic self-presentation. One hundred and twenty one women diagnosed with eating disorder according to the Eating Disorder Examination (EDE 16.0D) completed a battery of self-report questionnaires to assess external shame, self-criticism, perfectionistic self-presentation and depression. A mediated-moderation analysis was performed. Results showed that the path from external shame to self-criticism depends on the level of perfectionistic self-presentation whereas the effect of self-criticism on depression is constant. Thus, there is an interaction between external shame and perfectionistic self-presentation on self-criticism which, in turn, affects depression. The internalization of an ideal-self sets up a standard that once compared to the actual self, displays negative self-evaluations and feelings that individuals see as reflecting a bad, inferior and flawed self. In this context, a perfectionistic self-presentation is used to create positive images on the minds of others. Although this style of organization is an adaptive way to deal with specific social contexts once it functions as a buffer in the relationship between shame and self-criticism, perfectionistic self-presentation seems to be a useless strategy since it does not prevent them from depression. Implications for future research are discussed
valiação da qualidade espermática através do exame andrológico e volume testicular em ovinos sem raça definida
O objetivo do presente estudo foi avaliar a qualidade espermática de ovinos sem raça definida da Baixada Maranhense, Maranhão/Brasil, através dos parâmetros seminais correlacionando com o volume testicular. Para tanto foram utilizados 13 machos com média de idade de três anos , sendo estes submetidos ao exame andrológico de acordo com o preconizado pelo Colégio Brasileiro de Reprodução Animal (1998) e para o volume testicular utilizou-se a fórmula do cilindro (VTC= 2 [(LARG/2)2 x x COMP]). O testículo direito apresentou largura média de 6,23 ± 0,92 cm, comprimento médio de 9,34 ± 1,34 cm e espessura de 5,42 ± 0,64 cm, enquanto no testículo esquerdo obteve-se média de 6,15 ± 0,96, 9,65 ± 1 e 5,57 ± 0,57 para largura, comprimento e espessura respectivamente. Quanto à circunferência escrotal apresentou média de 26,14 ± 2,14 x 106 cm. Para o volume testicular a formula do cilindro obteve média de 588,56 e 587,01 cm3, testículo direito e esquerdo, respectivamente. Com os resultados obtidos, conclui-se que os valores seminais dos ovinos da baixada maranhense estão abaixo do preconizado para ovinos adultos e que o volume testicular aliado às características seminais é a forma mais eficaz de estimar a produção espermátic
