Occurrence of Symphyla (Myriapoda) in the region of the Upper Solim?es River, Amazonas, Brazil
Morais, José Wellington de;Silva, Ester Paix?o da;
Pesquisa Agropecuária Brasileira , 2009, DOI: 10.1590/S0100-204X2009000800028
Abstract: the present work aimed at identifying the symphyla species diversity and abundance in various land-use systems under different degrees of intensification in western amazonia. this is the first inventory of symphyla in primary and secondary forest, crops, agroforestry systems and pastures which was carried out in benjamin constant municipality, in the region of the upper solim?es river, brazil. samples (n = 101) were collected using a metal corer, and the symphylan extraction was carried out using berlese-tullgren funnels. two genera and three species of symphylans were encountered. considering the diversity encountered in amazonian inventories, with only four genera and five known species overall, the three species found in the present study are considered a reasonable representation of the regional diversity. two of the hanseniella species found have been known to cause plant damage.
Work Capacity of the Elderly: Assuming An-other Social Identity in the Contemporary World  [PDF]
Jo?o Henrique de Morais Ribeiro, Raul Paiva dos Santos, Deusdete Inácio de Souza Junior, Daniele Sirineu Pereira, José Vitor da Silva, Maria Angélica Mendes
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.310004
Abstract: This is a theoretical study on the work capacity of elderly people based on the Social Identity Theory—SIT. In that perspective, work capacity can be considered as the result of a dynamic process. It refers to the worker’s skills to execute professional activities according to the job requirements and his/her health condition. The SIT aims to highlight the existing impact on people’s behavior when they find themselves members of social categories and, therefore, it involves the operation of three psychological processes, which are: social categorization, social identification and social comparison. Thus, one can assume that society characterizes the elderly people as belonging to the retired group, and from a capitalist perspective, considers these people as unproductive. Their identity is linked to workers who are active in the job market; in addition, the chronological determinant of age does not impede elderly people from continuing in the job market. When elderly people are considered capable of developing their activities, whether professionally or not, and start to play new social roles, the start of the transformation in the conception of old age is perceived. In view of this panorama, a Conceptual Theoretical base is proposed, aiming to locate the phenomenon “work capacity” inside the aging process as this capacity is centered on the advanced activities of daily living.
Prevalence of high frequency hearing loss consistent with noise exposure among people working with sound systems and general population in Brazil: A cross-sectional study
Regina P El Dib, Edina MK Silva, José F Morais, Virgínia FM Trevisani
BMC Public Health , 2008, DOI: 10.1186/1471-2458-8-151
Abstract: This was a cross-sectional study comparing 177 participants in two groups: 82 sound technicians and 95 controls (non-sound technicians). A questionnaire on music listening habits and associated complaints was applied, and data were gathered regarding the professionals' numbers of working hours per day and both groups' hearing complaint and presence of tinnitus. The participants' ear canals were visually inspected using an otoscope. Hearing assessments were performed (tonal and speech audiometry) using a portable digital AD 229 E audiometer funded by FAPESP.There was no statistically significant difference between the sound technicians and controls regarding age and gender. Thus, the study sample was homogenous and would be unlikely to lead to bias in the results. A statistically significant difference in hearing loss was observed between the groups: 50% among the sound technicians and 10.5% among the controls. The difference could be addressed to high sound levels.The sound technicians presented a higher prevalence of high frequency hearing loss consistent with noise exposure than did the general population, although the possibility of residual confounding due to unmeasured factors such as socioeconomic status cannot be ruled out.Music is ever present in our daily lives, establishing a link between human beings and the arts through the senses and pleasure. However, if we use music inappropriately, that is, if we make abusive use of the duration, intensity and/or frequency of exposure to music, the noise may have an adverse impact on our hearing function.High frequency of hearing loss consistent with noise exposure (noise-induced hearing loss, NIHL), excluding cases of acute acoustic trauma, is characterized by the gradual and progressive loss of hearing acuity. NIHL occupies the second place among the most common hearing illnesses, only surpassed by presbyacusis [1,2].In Brazil, noise has only been recognized as an ambient pollutant since March 1991 [3].

Abstract: the assessment of a patient's perception of health-related quality of life (qol) may reflect the effects of a disease or treatment on the patient's daily life satisfaction and well-being. the purpose of this study was to evaluate self-reported quality of life in traumatic brain injury patients, by using the whoqol-bref, and search for correlations between questionnaire scores and patients' social-demographic and clinic characteristics. participants were 120 patients with brain damage who finished a rehabilitation program at aacd (association for assistance to disabled children). data were statistically analysed. mean scores at all whoqol-bref domains and mean global scores were above 60 points (0-to-100 scale). moderate correlations were found between global qol and educational level (p<0.05) and social adjustment (p<0.01). patients who were able to walk, with higher income and educational level, and better socially adjusted (studying or working) reported a better quality of life.
Identification of flexural stiffness parameters of beams
Espíndola, José Jo?o de;Silva Neto, Jo?o Morais da;
Journal of the Brazilian Society of Mechanical Sciences , 2001, DOI: 10.1590/S0100-73862001000200008
Abstract: a three degree of freedom model of the dynamic mass at the middle of a test sample, resembling a stockbridge neutraliser, is introduced. this model is used to identify the hereby called equivalent complex cross section flexural stiffness (ecfs) of the beam element which is part of the whole test sample. this ecfs, once identified, gives the effective cross section flexural stiffness of the beam as well as its effective damping, measured as the loss factor of an equivalent viscoelastic beam. the beam element of the test sample may be of any complexity, such as a segment of stranded cable of the acsr type. these data are important parameters for the design of overhead power transmission lines and other cable structures. a cost function is defined and used in the identification of the ecfs. an experiment, designed to measure the dynamic masses of two test samples, is described. experimental and identified results are presented and discussed.

O custo de abandono nas empresas petrolíferas
Santos, Odilanei Morais dos;Marques, José Augusto Veiga da Costa;Silva, Paula Danyelle Almeida da;
Revista Contabilidade & Finan?as , 2006, DOI: 10.1590/S1519-70772006000200005
Abstract: oil industry activities are typically hazardous. when exploratory investments succeed, great rewards are achieved. therefore, abandonment cost is an essential component that must be contemplated in any economic feasibility analysis of oil and gas exploration and production projects. such costs are extremely high and in some cases they can exceed the investments to build infrastructure and install equipments necessary for production. the main goal of this study is to investigate both the theoretical framework and the existing standards used by oil companies to recognize abandonment costs in their books in order to give a proper understanding on the accounting information produced by these companies. abandonment costs valuation must be taken into consideration as part of the capitalized cost of assets (oil wells, equipments and facilities) giving rise to a liability account conveying the amount related to future obligations of dismantlement, removal and restoration of oil fields. such practice has been implemented by sfas 143 in order to provide uniformity to information released by oil industry companies.
Correlations Between the Collagen Content of the Human Left Ventricular Myocardium, Measured by Biochemical and Morphometric Methods
Lopes José Duarte de Morais,Gomes Roseli Aparecida da Silva,Hial Valdemar,Lopes Isabel Cristina Rezende
Arquivos Brasileiros de Cardiologia , 2002,
Abstract: OBJECTIVE: To assess, in myocardium specimens obtained from necropsies, the correlation between the concentration of hydroxyproline, measured with the photocolorimetric method, and the intensity of fibrosis, determined with the morphometric method. METHODS: Left ventricle myocardium samples were obtained from 45 patients who had undergone necropsy, some of them with a variety of cardiopathies and others without any heart disease. The concentrations of hydroxyproline were determined with the photocolorimetric method. In the histologic sections from each heart, the myocardial fibrosis was quantified by using a light microscope with an integrating ocular lens. RESULTS: A median of, respectively, 4.5 and 4.3 mug of hydroxyproline/mg of dry weight was found in fixed and nonfixed left ventricle myocardium fragments. A positive correlation occurred between the hydroxyproline concentrations and the intensity of fibrosis, both in the fixed (Sr=+0.25; p=0.099) and in the nonfixed (Sr=+0.32; p=0.03) specimens. CONCLUSION: The biochemical methodology was proven to be adequate, and manual morphometry was shown to have limitations that may interfere with the statistical significance of correlations for the estimate of fibrosis intensity in the human myocardium.
