Foram utilizados 24 animais admitidos no Serviço de Cirurgia de Grandes Animais da Faculdade de Medicina Veterinária e Zootecnia - UNESP - Botucatu com queixa de lombalgia. Estes animais foram submetidos a exame físico para confirmar a existência de alteração toracolombar e então aos exames termográfico e ultra-sonográfico. O exame termográfico foi utilizado para o mapeamento das áreas lesadas da região e a ultra-sonografia para a caracterização das lesões. As lesões encontradas foram a desmite supraespinhosa, desmite interespinhosa, osteoartrite intervertebral dorsal e síndrome dos processos espinhosos ("kissing spines"). Foi constatada a existência de relação entre o tipo de atividade exercida pelo animal com o tipo de lesão encontrado. Nos animais que desempenhavam prova dos três tambores houve um predomínio de lesões na região torácica caudal, toracolombar e lombar cranial, sendo a osteoartrite intervertebral e a desmite interespinhosa as afecções mais encontradas. Nos animais de apartação observou-se a maioria das lesões na região lombar caudal, sendo predominantes a osteoartrite intervertebral e a desmite supraespinhosa. Já nos animais de rédeas o local preferencial de lesão foi a região média lombar, com predomínio de osteoartrites intervertebrais, desmites supraespinhosas e miosites. A termografia associada à ultra-sonografia se mostraram eficientes no diagnóstico das lesões toracolombares destes eqüinos. / Abstract: The objective of this study was to appreciate the efficacy of thermography and ultrassonography for toracolombar lesions diagnostic in athletic American Quarter Horse and associate this to the different kinds of athletic modalities. Was used 24 animals accepted in Cirurgia de Grandes Animais service of the Faculdade de Medicina Veterinária e Zootecnia - UNESP - Botucatu with lombalgy report. Those animals was submitted to a physical exam to confirm the toracolombar pain existence and so, to the thermographic and ultrassonographic exams. The thermographic exam was performed for mapping the lesioned areas and the ultrassonographic exam, for the characterization of this lesions. After the exams, supraspinal desmitis, interspinal desmitis, dorsal invertebral osteoarthritis and spinous processes impingement (kissing spines) was found. The relation between the modality of athletic activity performed by the animal and the type of lesion ranged was verify. The barrel race horses presents prevalence of lesions in thoracic caudal, toracolombar and lumbar cranial regions and the invertebral osteoarthritis and interspinal desmitis was the prevalence on affections. In cutting horses, was verify that the major part of lesions was localized on caudal lumbar region with the prevalence of invertebral osteoartrite and supraspinal desmitis. In reining animals the prevalence of lesions was in medial lombar region, where invertebral osteoartrite, supraspinal desmitis and miositis was verify with constancy. The thermography in association with ultrassonography shows efficacy in toracolombar injuries diagnoses for this horses. / Mestre

The assessment of performance for PEM Fuel Cells (PEMFC) at the stack, Single Repeating Unit (SRU), and Membrane Electrode Assembly (MEA) level is dominated by the evaluation of polarization curves. However, polarization curves do not provide adequate detail as to the origin of the inefficiencies of the fuel cell performance and information on these sources of origin are critical to understand and address topics such as material selection, optimal operating conditions, and overall robust and reliable cell and stack design characteristics. To the purpose of understanding the origin of the inefficiencies underlying the fuel cell polarization curve a series of additional experimental and analysis techniques must be applied and from the resultant data the origin of the inefficiencies can then be assigned to kinetic, ohmic, and mass transport loss categorizations. Further, through a combination of the diagnostic methods further resolution can be implied down to the contribution of the individual components to the relative voltage loss categories. In this topic, a methodology will be presented and discussed that achieves and demonstrates this process.
