Obesity is a risk factor in the development of several respiratory diseases. Lung volumes tend to be decreased, especially expiratory reserve volume, increasing expiratory flow limitation during tidal breathing. Barometric whole-body plethysmography is a non-invasive pulmonary function test that allows a dynamic study of breathing patterns. The objective of this study was to compare pulmonary function variables between obese and non-obese cats through the use of barometric whole-body plethysmography. Nine normal-weight and six obese cats were placed in the plethysmograph chamber, and different respiratory variables were measured. There was a significant decrease in tidal volume per kilogram (P=0.003), minute volume per kilogram (P=0.001) and peak inspiratory and expiratory flows per kilogram (P=0.001) in obese cats compared with non-obese cats. Obesity failed to demonstrate a significant increase in bronchoconstriction index variable enhanced pause (Penh), as previously reported in humans and dogs. The results show that feline obesity impairs pulmonary function in cats, although a significant increase in bronchoconstriction indexes was not observed. Non-invasive barometric whole-body plethysmography can help characterise mechanical dysfunction of the airways in obese cats.

It's common knowledge that education is an essential aspect to promote the development process of a country. But, what exactly means development? Until what point does formal education influences a country development? This work seek to bring new perspectives to these matters by analyzing the influence of human capital on development, basing the theoretical concepts in authors like Theodore W. Schultz and researchers from the Frontiers of Development Economics, like Amartya Sen and Irma Adelman

In Brazil, the discussion about thereplacement of analog television signals to digitaland its impact on society, in media companies andgovernment began in the 90s. Embryonic steps towardsdigitalisation of the television signal ground were thegovernment of Fernando Collor de Mello (1990-1992),with advances during the government of FernandoHenrique Cardoso (1994-2001) and in the governmentof Luiz Inacio Lula da Silva (2002). The academy startsthe discussion in 1996. This article aims to bring to lightthe results obtained from the survey Digital television:a historical perspective , which received the supportof CNPq for funding of two scholarships for scientifi cinitiation between August 2008 and July 2009. Theproject sought to identify what has been published onthe subject in the fi eld of Social Sciences and from threemacrodescritores (information management, publicpolicy and value chain), providing the li ing of a virtualcollection Zotero bibliographic innovative platform.The mapping serves to show the growing interest anddevelopment of research in the country during theperiod - when the number jumped to three works inthe fi rst seven years (1995-2001) to 198 in the last sevenyears (2002-2008). The research sought to identify themajor authors and works related to digital televisionand published in the country. The survey took intoaccount books, articles published in books, journals,Annals of Compós and Intercom, and dissertations andtheses. Data and refl ections on the survey are containedin this communication.

Para a realização deste experimento, foram utilizados um rebolo de óxido de alumínio instalado em uma retificadora plana, um dispositivo em forma de balança juntamente com o sensor de deslocamento, um sistema de aquisição de sinais e um dressador de ponta única de diamante. O processamento digital dos dados foi obtido com o software Matlab. Nos ensaios, foram aplicados diferentes graus de recobrimento e profundidade de dressagem e comparada a agressividade obtida. A partir dos dados resultantes, os parâmetros RMS, DPO e DPKS mostraram-se bons indicadores para a operação. Também ficou comprovado que para recondicionar e definir novas características para o rebolo é necessária a remoção de 120 um. Do estudo do espectro do dinal de EA, notou-se que não há componentes hormônicas com frequência superior a 200 KHz.
