Right-to-left shunt determination in dog lungs under inhalation anesthesia with rebreathing and non-rebreathing system

OBJETIVO: Comparar a formação de shunt venoso-arterial em pulmões de cães submetidos a anestesia geral inalatória utilizando-se sistemas de anestesia com e sem reinalação, com fração inspirada de oxigênio de 0,4 e 0,9, respectivamente. MÉTODOS: Empregaram-se 20 cães induzidos com tiopental sódico (30mg/kg) e mantidos com sevoflurano (3%) e alocados em dois grupos (n=10); os animais de GI foram ventilados com modalidade controlada em sistema semifechado, sem reinalação, F I O2 = 0,9, e os de GII, com modalidade controlada, sistema semifechado, com reinalação e F I O2 = 0,4. Os atributos analisados durante o experimento foram: freqüência cardíaca, pressão arterial média, shunt pulmonar venoso-arterial, hematócrito, hemoglobina, pressão parcial de oxigênio arterial, pressão parcial de oxigênio no sangue venoso misto, saturação de oxigênio no sangue venoso misto, pressão parcial de dióxido de carbono arterial e pressão de vapor de água nos alvéolos (P VA). RESULTADOS: A P VA foi significativamente maior em GII. A análise estatística dos valores encontrados de shunt mostrou que GI e GII apresentaram diferenças significativas, sendo que os resultados de GI são maiores que os de GII em todos os momentos avaliados. Já a análise de momentos dentro de um mesmo grupo não demonstrou diferenças. CONCLUSÃO: O sistema de anestesia sem reinalação com F I O2 = 0,9 desenvolveu maior grau de shunt pulmonar venoso-arterial que o sistema de anestesia com reinalação e F I O2 = 0,4. A umidificação dos gases em GII contribuiu para diminuir o shunt.

Ablation of the ability to control the right-to-left cardiac shunt does not affect oxygen uptake, specific dynamic action or growth in the rattlesnake Crotalus durissus

The morphologically undivided ventricle of the heart in non-crocodilian reptiles permits the mixing of oxygen-rich blood returning from the lungs and oxygen-poor blood from the systemic circulation. A possible functional significance for this intra-cardiac shunt has been debated for almost a century. Unilateral left vagotomy rendered the single effective pulmonary artery of the South American rattlesnake, Crotalus durissus, unable to adjust the magnitude of blood flow to the lung. The higher constant perfusion of the lung circulation and the incapability of adjusting the right-left shunt in left-denervated snakes persisted over time, providing a unique model for investigation of the long-term consequences of cardiac shunting in a squamate. Oxygen uptake recorded at rest and during spontaneous and forced activity was not affected by removing control of the cardiac shunt. Furthermore, metabolic rate and energetic balance during the post-prandial metabolic increment, plus the food conversion efficiency and growth rate, were all similarly unaffected. These results show that control of cardiac shunting is not associated with a clear functional advantage in adjusting metabolic rate, effectiveness of digestion or growth rates. © 2013.

Injustiça e poder segundo Noam Chomsky

Injustice and power according to Noam Chomsky. In the beginning of the Politics, Aristotle establishes the two lesser forms of sociability: the relationships between man and woman and between master and the slave. In this context, he observes that “Hellenes are natural masters of barbarians” and the reason is that Greeks know philosophy and barbarians still resort to violence (ARISTOTLE, Politics, 1252a.). Shortly after defines “just war” as a war that has a fair cause, that is, which is well justified by philosophy or a fair speech (ARISTOTLE, Politics, 1255a.). This scene briefly expresses the manner in which the USA understands their role in the contemporary world. Chomsky points out the political use of massive military force of his country and denounces how it articulates internally and externally. He affirms that politics is excessively submitted to “ideology”, to doxa, as opposed to natural sciences. His militancy, thus, only advocates freedom and unrestricted right to information. In Camelot, the Kennedy years (1993), for example, the MIT’s professor collects information from congressmen’s speeches and government officials and from secret documents made public and he explicits the methods and actions of the US government. Thereby he can conclude that the US has, for historical reasons, an internal posture that is advocate or contrary to what they imposes to other countries. Power and justice on the one hand, force and injustice on the other –according to their own political discourse.

Competências em relações públicas: qualidades profissionais para atuação em comunicação pública

The professional skills desirable to graduates in public relations are defined by many authors of scientific specialized literature, and are continually developed throughout the academic life of the PR student. There are many opportunities of learning aspects such as professional behavior, responsibilities and challenges in the activity's various branches. The field of public communication has particularities that must be respected in order to have an effective communication process with quality and focused vision for citizenship building. This paper examines the specificities of public communication in Brazil, characterized by innovations of the right to information on public social policies, and offers a contribution to the characterization of the necessary skills and abilities of the communicator of this field in the contemporary scenario

Estado e burocracia: limites de aplicação da Lei de Acesso a Informações no Brasil

Saudada como consequência de um complexo processo de evolução do arcabouço jurídico-institucional brasileiro, a Lei Federal 12.527, denominada Lei de Acesso a Informações, sancionada em 18 de novembro de 2011 e regulamentada no âmbito do Poder Executivo federal pelo Decreto 7.724, de 16 de maio de 2012, atende o pressuposto do direito à informação fixado pela Constituição Federal de 1988. Valores e práticas historicamente construídos podem significar obstáculos e resistências importantes à sua aplicação. Características do próprio texto legal, que vêm à tona quando comparado aos seus congêneres internacionais, também sinalizam possíveis complicadores. Este artigo indica limites que a Lei de Acesso a Informações pode enfrentar à sua consolidação, originários principalmente do campo da cultura político-institucional, que se tornam mais nítidos com o exame de características brasileiras em comparação com outros países que possuem dispositivos semelhantes.

Comunicação pública, transparência e políticas públicas: avaliação de informações em portais brasileiros de governo

An expansion of the professional field of Public Relations can be seen nowadays, influenced by factors such as the increasing use of information and communications technologies for the dissemination of information on public management and the potential creation of dialogue between government and citizens. Despite this trend, there is still a need for specific knowledge about normative aspects of public communication generated by governments on the internet and its role in the fulfillment of the right to information. This article offers a contribution to fulfill the gap of guidelines and standards for professional performance. It describes the results of empirical research which identified the potential contribution of government web portals of the main cities of São Paulo, in the southeastern Brazil, to the strengthening of citizenship, considered in its dimension of exercising the right to information about public policies, particularly those which have an impact on education. The depth and breadth of information were investigated according with twelve categories of evaluation: history; diagnoses; goals; goals; resources and current actions; planned resources and actions; efficiency; effectiveness; impact; cost-effectiveness; user satisfaction; and equity. The data found on the analyzed portals correspond to the average of 11% of which was considered, under the theoretical-methodological context of the research, as information necessary to comprise the full characterization of a public policy in relation to the categories of assessment. Opportunities to improve government web portals were detected, for which we suggest communication management strategies.

Manuais de conduta em mídias sociais e sua contribuição para a democracia digital: um estudo de manuais brasileiros

Information and communication technology have contributed to the realization of the ideals of citizen participation in public decisions, as well as to help in fighting corruption and wrongdoing in government. After all, democracy entails the right to information. The government, in many spheres, has encouraged the responsible use of the internet. Conduct manuals and standards have been published for public segments to direct the responsible use of these tools by their agents. This article aims to determine whether the manuals comply with the principles of digital democracy. Conduct manuals were analyzed in digital media from four Brazilian public organizations: Embrapa; Department of Communication of the Federal Government; Judiciary and Health Department of the Federal District. As a methodology, content analysis, based on criteria focused on transparency and encouraging civic engagement was used.

Comunicação pública para cidadania no avanço das redes sociais oficiais

The advancement in the deployment of social networks by governments can generate public communication initiatives, which may contribute to the strengthening of citizenship, understood as the exercise of the right to information about public management. This article describes results of research which assessed, through content analysis, the breadth and depth of information offered by the state government of São Paulo in news stories accessed through the social networks Twitter, YouTube, Facebook and Orkut which publicize purposes, lines of action and limits of public policies of immediate impact for citizenship, in the areas of welfare, health, education and environment. Results indicate that the analyzed sample contains, on average, from 28% to 40% of all information deemed necessary for the comprehensive and plural characterization of a public policy, according to the theoretical-methodological context of the research.

Internet e democracia: a qualidade da informação sobre políticas públicas de cultura em portais de governo

Public communication comprises the dissemination of information on the various aspects of public management, with transparency and accountability, including the use of the existing technological resources. Particularly in the field of cultural policies, the right to information must be exercised as a contribution to political participation and economic expansion. This paper presents the results of research that was investigated, through analysis of the content under thirteen categories of evaluation, of the quality of information on cultural policies in web portals of the different spheres of government in Brazil. The results show the lack of information on the processes of development and implementation of policies in that field.

Comunicação pública e acesso à informação: análise da atuação da SABESP em plataformas virtuais

This undergraduate research final paper analyzed the communication process carried out by the São Paulo State Water and Sanitation Company - Sabesp from the perspective of public communication, social capital and right to information theories. By monitoring Sabesp's institutional fanpage and website from 24 to 30 August 2015, it sought to assess the performance of Sabesp in disclosing public information on the context of the water supply crisis in São Paulo, concerning the fulfillment of requirements of the Right to Information Law (12.527/2011) and the need for interaction and dialogue between the institution and its stakeholders, taken as principles of public communication. The results suggest that digital media can enhance information flow and contribute to foster public relations and civic participation, but there are opportunities for Sabesp to improve communication and reach greater transparency

Product development process: Using real options for assessments and to support the decision-making at decision gates

Enterprises need continuous product development activities to remain competitive in the marketplace. Their product development process (PDP) must manage stakeholders' needs - technical, financial, legal, and environmental aspects, customer requirements, Corporate strategy, etc. -, being a multidisciplinary and strategic issue. An approach to use real option to support the decision-making process at PDP phases in taken. The real option valuation method is often presented as an alternative to the conventional net present value (NPV) approach. It is based on the same principals of financial options: the right to buy or sell financial values (mostly stocks) at a predetermined price, with no obligation to do so. In PDP, a multi-period approach that takes into account the flexibility of, for instance, being able to postpone prototyping and design decisions, waiting for more information about technologies, customer acceptance, funding, etc. In the present article, the state of the art of real options theory is prospected and a model to use the real options in PDP is proposed, so that financial aspects can be properly considered at each project phase of the product development. Conclusion is that such model can provide more robustness to the decisions processes within PDP.
