Rotational Oscillation Effect on Flow Characteristics of a Circular Cylinder at Low Reynolds Number  [PDF]
Alice Rosa da Silva, Aristeu da Silveira-Neto, Ant?nio Marcos Gon?alves de Lima
World Journal of Mechanics (WJM) , 2015, DOI: 10.4236/wjm.2015.510019
Abstract: Two dimensional numerical simulations of flow around a rotationally oscillating circular cylinder were performed at Re = 1000. A wide range of forcing frequencies, fr, and three values of oscillation amplitudes, A, are considered. Different vortex shedding modes are observed for a fixed A at several values of fr, as well as for a fixed fr at different values of A. The 2C mode of vortex shedding was obtained in the present study. It is important to point out that this mode has not been observed by other investigators for rotationally oscillating case. Also, it is verified that this mechanism has great influence on the drag coefficient for high frequency values. Furthermore, the lift and pressure coefficients and the power spectra density are also analyzed.

Abstract: the study intended to analyze the conceptions of academics of nursing about the nurse's work. through a questionnaire with students of the first, fifth and nineth semesters, it was verifyed that the answers of the students of the last semester are closer to the practice of the profission, because these students see the nurse as key of the work in health. the academics of the first semester mention only the humanitarian dimension of the work. and the ones of the fifth semester evidence the administration of the care and the work in group as actual in the daily one of the nurse. it can be affirmed that education plays an important role in the construction of the conceptions of the students, having, since early, to approach them of the reality of the practical professional.
Numerical simulation of two-dimensional complex flows around bluff bodies using the immersed boundary method
Silva, Ana Lúcia F. de Lima e;Silva, Alice Rosa da;Silveira Neto, Aristeu da;
Journal of the Brazilian Society of Mechanical Sciences and Engineering , 2007, DOI: 10.1590/S1678-58782007000400006
Abstract: this paper presents a two-dimensional numerical simulation of flows around different bluff bodies, at re = 100 and 200, using the immersed boundary (ib) method, as a sequence of a previous work. the force density term required by the ib method is obtained with the virtual physical model (vpm). simulations were carried out for two circular cylinders of different diameter in tandem, two cylinders of the same diameter in tandem and two cylinders placed in side by side arrangement. the configurations of seven cylinders in a 'v' arrangement, for angles of 40o < a < 180o, were also simulated. a configuration of 23 different bluff bodies, representing a transverse cut in a central tower of an offshore structure, has been also simulated and the results were compared with a single compact square, of equivalent size. the strouhal number, the drag and the lift coefficients were also calculated. the strouhal number is calculated using the fast fourier transform (fft) of the lift coefficient temporal distribution. visualization of the vorticity and pressure fields and the streamlines are presented for each simulation showing the flow dynamics and patterns. it was possible to verify that the ib method with vpm is a powerful methodology to simulate flows in the presence of complex geometries.
Numerical simulations of flows over a rotating circular cylinder using the immersed boundary method
Silva, Alice Rosa da;Silveira Neto, Aristeu da;Lima, Antonio Marcos G. de;Rade, Domingos Alves;
Journal of the Brazilian Society of Mechanical Sciences and Engineering , 2011, DOI: 10.1590/S1678-58782011000100014
Abstract: in this paper, numerical simulations of incompressible flows around rotating circular cylinders have been performed. the two-dimensional navier-stokes equations are solved by using a cartesian non-uniform grid. the immersed boundary method (ibm) with the virtual physical model (vpm) was used in order to model the presence of the circular cylinder in the flow. the fractional time step method was used to coupling the pressure and velocity fields. the simulations were carried out for reynolds numbers equals to 60, 100 and 200 for different specific rotations. the effects of rotation on flow characteristics and fluctuating forces were investigated. the strouhal number, obtained by performing the fast fourier transform (fft) of the temporal distribution of the lift coefficient, and the pressure coefficients, were also been calculated. vorticity contours are presented considering different values of the reynolds number and specific rotation. the numerical results obtained are compared to those obtained by other authors and the usefulness of the numerical methodology composed by the combination of the ibm with the vpm to simulate flows in the presence of mobile bodies is highlighted.

Abstract: O zumbido, som percebido pelo indivíduo sem que haja estímulo externo, resulta da intera o dinamica de centros do sistema nervoso central, incluindo vias auditivas e n o auditivas. O resultado desta intera o, especialmente sistema límbico e sistema nervoso aut nomo, seria responsável pelo desencadeamento de associa es emocionais negativas e rea es de inc modo em pacientes com zumbido. A ansiedade, condi o fisiológica inerente ao ser humano, quando exacerbada gera um transtorno de humor, comprometendo o pensamento, o comportamento e a atividade psicológica. Se um estímulo interno ou externo for interpretado como perigoso ou amea ador, desencadeará uma rea o emocional caracterizada como estado de ansiedade. Este artigo tem como objetivo realizar uma revis o da literatura sobre a rela o do zumbido e da ansiedade. Em se tratando do zumbido, a forma como o som é percebido pode ser alterado pela ansiedade, agu ando assim a sensibilidade para detectar sons que parecem uma amea a em potencial, pois para muitos o zumbido é sin nimo de enfermidade grave. A etiologia do desenvolvimento da depress o e ansiedade pode estar relacionada ao zumbido. Muitos adquirem esse sintoma por problemas físicos e, consequentemente, desenvolvem a depress o e a ansiedade. Outros com graus diferentes de angústias adquirem o zumbido devido ao comprometimento emocional. Dessa forma, existe um vínculo entre o zumbido e problemas emocionais, mas nem sempre é fácil identificar o precursor. Estudos demonstram que pacientes acometidos pelo zumbido apresentam maior tendência ao suicídio, depress o e ansiedade. Além disso, referem o efeito aditivo da ansiedade e da depress o na qualidade de vida e no zumbido dos indivíduos. Tinnitus is a sound perceived without external stimulus, and results from the dynamic interaction of the centers in the central nervous system, including non-auditory and auditory ways. The result of this interaction, especially with the limbic system and autonomic nervous system, would be responsible for triggering negative emotional associations and distress in patients with tinnitus. Anxiety, a physiological condition inherent to human beings, when exacerbated, generates a mood disorder, affecting thinking, behavior and physiological activity. If an inner or outer stimulus is interpreted as dangerous or threatening, it may trigger an emotional reaction characterized as a state of anxiety. This work aims to review the relationship between tinnitus and anxiety. The tinnitus sound is perceived can be altered by anxiety, thereby, sharpening the sensitivity in detecti

Abstract: objective: although bipolar disorder is a major contributor to functional impairment worldwide, an independent impact of bipolar disorder and ageing on functioning has yet to be demonstrated. the objective of the present study was to evaluate the effect of bipolar disorder on age-related functional status using matched controls as a standard. method: one-hundred patients with bipolar disorder and matched controls were evaluated for disability. age-related effects controlled for confounders were cross-sectionally evaluated. results: patients were significantly more impaired than controls. regression showed effects for aging in both groups. the effect, size, however, was significantly stronger in patients. conclusion: bipolar disorder was an important effect modifier of the age impact on functioning. while a longitudinal design is needed to effectively demonstrate this different impact, this study further depicts bipolar disorder as a chronic and progressively impairing illness.

Abstract: O presente artigo tem como objetivo discutir a constitui o da língua de sinais como mediadora para a compreens o do português escrito para leitores surdos n o alfabetizados. Procuramos, neste trabalho, abordar a notícia, como unidade de texto que se constitui através de determinadas rela es como acontecimento da cidade. Enquanto projeto de busca de significado, a leitura de jornais em língua de sinais foi geradora de novas experiências para os leitores surdos, através da apropria o e transforma o de significados das notícias impressas, o leitor surdo se constitui autor e produtor de seu próprio texto. This article aims to discuss how sign language mediates the understanding of written Portuguese for deaf non-literate readers. In this paper, we discuss news matter as text unit, constituted by means of certain relationships between the deaf reader and events occurring in the environment. As a project which intends to seek meaning, reading the paper in sign language generated new experience for deaf readers, though the appropriation and transformation of meaning of printed news, deaf readers can become authors and producers of their own texts.
