No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Agrárias. Programa de Pós-Graduação em Aquicultura, Florianópolis, 2013A hematologia consiste em uma análise rápida e prática para auxiliar o diagnóstico do desequilíbrio homeostático em peixes. Este estudo determinou os intervalos de referência sanguíneos em importante bagre nativo da América do Sul, Sorubim lima, criado na região do pantanal e descreve as características morfológicas e citoquímicas das células. Um total de 92 peixes de piscicultura foram examinados para determinação dos intervalos de referência 25 - 75%, concentração de proteínas plasmáticas totais, hemoglobina, número total de eritrócitos (ERT), hematócrito, volume corpuscular médio (VCM), concentração da hemoglobina corpuscular média (CHCM), trombócitos totais e leucócitos totais (LEU). PAS com amilase salivar, azul de bromofenol, sudan black B e azul de toluidina (metacromasia) foram as colorações citoquímicas empregadas para sinalizar glicogênio, proteínas, lipídeos e núcleos em trombócitos e leucócitos. Nas extensões sanguíneas, monócitos, linfócitos, neutrófilos, basófilos, eosinófilos, LG-PAS e trombócitos foram observados. Resultados semelhantes a outros siluriformes foram observados nas características morfológicas de neutrófilos e eusinófilos. ERT, hematócrito e VCM apresentaram índices com as menores variações, em relação a demais pimelodídeos. Diferentemente de outros peixes siluriformes, S. lima apresentou simultaneamente eosinófilos e basófilos circulantes. Abstract : Haematology consists in a rapid and practical analysis to assist the diagnosis of fish homeostatic imbalance. This study determined the blood reference intervals in an important native South American catfish farmed in the brazilian pantanal wetland, Sorubim lima, and describes the morphological and cytochemical characteristics of cells. A total of 92 fish reared in a fish farm were examined for reference intervals 25 - 75% of total plasmatic protein, hemoglobin, red blood cell count (RBC), hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC) and total thrombocyte and leukocyte count (WBC). PAS with salivary amylase, bromophenol blue, sudan black B and toluidine blue (metacromasy) were the cytochemical stains employed to signal glycogen, proteins, lipids and nuclei in thrombocytes and leucocytes. In the blood smears, monocytes, lymphocytes, neutrophils, basophils, eosinophils, LG-PAS and thrombocytes were observed. Siluriforms similar results were observed in neutrophils and eosinophils morphology. Compared to other pimelodids, RBC, hematocrit and MCV showed index lowest variation. Differently from other siluriforms fishes, S. lima showed the concomitant presence of circulating eosinophils and basophils

No full textThe effect of the through-the-thickness compressive stress on mode II interlaminar fracture toughness
No full textThe effect of through-the-thickness compressive stress on the mode II interlaminar fracture toughness is investigated experimentally and replicated numerically. The modified Transverse Crack Tensile specimen recently proposed by the authors is used, together with an experimental device designed to apply a constant transverse compressive stress on the surface of the specimen. Experiments are conducted using IM7/8552 specimens for different compressive stresses, ranging from 0 to 100 MPa, covering all the practical applications commonly encountered in the aeronautical industry (e.g., tightened filled holes or bolted joints). It is shown that the mode II interlaminar fracture toughness increases with the applied compressive through-the-thickness stress. Finally, experiments are replicated using appropriate numerical models based on cohesive elements that take into account frictional effects. A good agreement between numerical predictions and experiments is found.</p

Virtual Instrumentation Applied To The Implementation Of Ieee Std 1459-2000 Power Definitions
No full textThis paper discusses the utilization of Virtual Instrumentation to the implementation and evaluation of different power definitions, so that classical formulations and new definitions can be compared without the necessity of acquiring different power meters or analyzers. Accordingly, the definitions of IEEE Standard 1459-2000 for the measurement of power quantities under distorted and unbalanced situations, have been digitally implemented. Thus, several power and power factor components related to the decomposition of the measured voltage and current signals have been obtained. The proposed PC-based Virtual Instrument uses a high performance acquisition board and isolated sensors and transducers. All digital algorithms and routines have been implemented by means of a graphical development system. Regarding to the implementation of STD 1459, this paper also proposes several different algorithms to the required decompositions of voltage, current and power components. © 2005 IEEE.200517121718Czamecki, L.S., What is wrong with the Budeanu concept of reactive and distortion power and why it should be abandoned?
