A construção da notícia no portal choike.org: comunicação alternativa na internet

This project aims to study the influence of information technology in the construction of new forms of citizenship. A large space as possible by the Internet allows the emergence of alternative news sources, as opposed to the means of mass communication. The research will take from the study of the news portal Choike.org. Maintained by civil society representatives, the website has a proposal to address topics that are infrequent in the media hegemony. To facilitate the study, we established a cut. Let's look at five bulletins Choike.org portal between the years 2005 and 2010 that address the issue of agrarian reform in Latin America, especially in Brazil. The issue is discussed by the media in general, however has more emphasis between the means of alternative journalism. For Choike.org portal, agrarian reform this intrinsically linked to social development. Therefore, this analysis seeks to highlight the role of new technologies as an important tool to aid discussion of the issue in the media as having specific focus to the issue of land reform

Web e jornalismo especializado: análise de conteúdo do portal jurídico Migalhas

Considering the context that integrates the internet and the information, the present paper has aimed to analyze the content from the juridical portal named Migalhas, more specifically the daily information–newsletter that is sent to its readers. Starting by the passage on the pathway of the internet, cyber culture and web journalism, and some concepts of news production, it is aimed to describe and evaluate, from the content of the proposed analyzes by Laurence Bardin, about general aspects, strategies and bulletin samples. Bringing a little of its history and description of the journalistic and news main points. The present paper approaches how these criteria, news value, and tools are chosen and used to reach the effectiveness of the proposal to take specific and fast information to the readers. Questions regarded to the opinionated character from the content were also stated as a way to evaluate its expressiveness

Deutsche Welle Brasil: construção da notícia e representação social

Zusammenfassung: In dieser Studie wurde untersucht, wie Nachrichten, die vom Nachrichtenportal Deutsche Welle in portugiesischer Sprache veröffentlicht werden, produziert werden und inwieweit sie Brasilien und Deutschland bezüglich kulturellen, politischen und wirtschaftlichen Aspekten repräsentieren. Der staatliche deutsche Auslandsrundfunk zeichnet sich durch seine internationale Reichweite aus und schafft Dialoge zwischen Deutschland und anderen Nationen. Angesichts der Schnittstelle zwischen Journalismus und Internet, haben wir uns auf den Sender Deutsche Welle, und dort vor allem auf die brasilianische Nachrichtenredaktion fokussiert. Dadurch war es möglich, den Kontext, in dem der analysierte journalistische Inhalt produziert wird, genau zu verstehen. Die Nachrichten wurden über einen Zeitraum von einer Woche im Portal gesammelt und anschließend einer quantitativen und qualitativen Inhaltsanalyse unterzogen (BARDIN, 2009). Die Ergebnisse zeigen, wie die Inhalte beide Länder repräsentieren und gleichzeitig die Redaktionsstrategie des Senders bestätigt wird. In Anbetracht des Effekts, den die Nachrichten und die übermittelte Repräsentation der beiden Länder in den Beiträgen auf die Meinungsbildung der Zielgruppe haben könnten, trägt diese Studie zum wissenschaftlichen Verständnis im journalistischen Bereich bei und regt zu weitere Studien über die Deutsche Welle an

Ovário-histerectomia vídeo-assistida com único portal em cadelas: estudo retrospectivo de 20 casos

O objetivo do presente estudo foi avaliar retrospectivamente as 20 primeiras ovário-histerectomias vídeo-assistidas com único portal (SPVA-OSH), realizadas por um cirurgião não proficiente nessa técnica. Vinte cadelas foram submetidas à laparoscopia para SPVA-OSH, com o auxílio de um endoscópio de 10mm, com canal de trabalho de 5mm, inserido por um trocarte, posicionado na região pré-púbica, e coagulação bipolar. O tempo cirúrgico médio foi de 22,95±5,17 minutos. Os cinco primeiros procedimentos consumiram mais tempo cirúrgico do que os demais. A abordagem aos pedículos ovarianos direito e esquerdo foram as etapas que apresentaram maior tempo de execução. Houve complicação leve ou moderada em seis (30%) das 20 cadelas operadas. As complicações foram: hemorragia leve ou moderada em um dos pedículos ovarianos em quatro (20%) cadelas e hemorragia grave, devido à punção do baço com agulha de Veress em dois (10%) animais. A SPVA-OSH foi realizada em cadelas por um cirurgião no início da curva de aprendizado, sem complicações maiores.

Estudo do sistema portal hepático no pato doméstico (Cairina moshata)

Estudou-se o comportamento do sistema portal hepático em 30 patos domésticos, adultos, machos e fêmeas. O sistema apresenta-se constituído por duas veias portais hepáticas: direita e esquerda. A veia portal hepática esquerda é formada por veias gástricas esquerdas (em número de 1 a 2), veias da margem ventral do ventrículo, veia pilórica e veia proventricular caudal. A veia portal hepática direita é formada pela veia mesentérica caudal, veia mesentérica cranial, veia proventrículo-esplênica e veia gastropancreaticoduodenal. A veia mesentérica caudal recebe tributárias do mesorreto, cloaca e junção ileocecocólica. A veia mesentérica cranial recebe tributárias jejunais (em número de 12 a 21) e se anastomosa com a veia mesentérica caudal, formando a veia mesentérica comum. A veia pancreaticoduodenal recebe duas veias gástricas direitas, constituindo assim a veia gastropancreaticoduodenal. A veia proventrículo-esplênica é formada pelas veias proventriculares dorsal e direita e pelas veias esplênicas.

Hemodynamic evaluation of the right portal vein in healthy dogs of different body weights

Background: Doppler ultrasonography is an important tool for evaluating hepatic portal hemodynamics. However, no study in dogs of different body weights, in the range encountered in routine clinical veterinary practice, has been reported. It can be difficult to obtain an ideal insonation angle when evaluating the main portal vein, so evaluation of the right portal vein branch has been described in humans as an alternative. The aim of this study was to analyze, through Doppler ultrasonography, the hemodynamics in the right portal vein branch in dogs of different body weights.Methods: Thirty normal dogs were divided in three groups by weight, in order to establish normal values for mean velocity, flow volume and portal congestion index of the right portal vein branch by means of Doppler ultrasonography.Results: In all dogs ideal insonation angles were obtained for the right portal vein branch. The average velocity was similar in the three groups, but the portal congestion index and the flow volume differed, showing that the weight of the dog can influence these values.Conclusion: Doppler ultrasonography for the evaluation of flow in the right branch of the portal vein could be a viable alternative, or complement, to examining the main vessel segment. This is especially so in those animals in which an ideal insonation angle for examination of the main portal vein is hard to obtain. In addition, the weight of the dog must be considered for the correct evaluation of the portal system hemodynamics, particularly for portal blood flow and the congestion index.

On the dynamics of free and excited oscillations of a simple portal frame foundation

In this paper we search for the dynamics of a simple portal structure in the free and in the periodic excitation cases. By using the Center Manifold approach and Averaging Method, we obtain results on both stability and bifurcation of equilibrium points and periodic orbits. (C) 2005 Elsevier Ltd. All rights reserved.

On saturation control of a non-ideal vibrating portal frame foundation type shear-building

In this paper, we examine the nonlinear control method based on the saturation phenomenon and of systems coupled with quadratic nonlinear ties applied to a shear-building portal plane frame foundation that supports an unbalanced direct cut-rent with limited power supply (non-ideal system). We analyze the equations of motion by using the method of averaging and numerical simulation. The interaction of the non-ideal structure with the saturation controller may lead to the occurrence of interesting phenomena during the forward passage through the several resonance states of the systems. Special attention is focused on passage through resonance when the non-ideal excitation frequency is near the portal frame natural frequency and when the non-ideal system frequency is approximately twice the controller frequency (two-to-one internal resonance).

Short comments on self-synchronization of two non-ideal sources supported by a flexible portal frame structure

A practical problem of synchronization of a non-ideal (i.e. when the excitation is influenced by the response of the system) and non-linear vibrating system was posed and investigated by means of numerical simulations. Two rotating unbalanced motors compose the mathematical model considered here with limited power supply mounted on the horizontal beam of a simple portal frame. As a starting point, the problem is reduced to a four-degrees-of-freedom model and its equations of motion, derived elsewhere via a Lagrangian approach, are presented. The numerical results show the expected phenomena associated with the passage through resonance with limited power. Further, for a two-to-one relationship between the frequencies associated with the first symmetric mode and the sway mode, by using the variation of torque constants, the control of the self-synchronization and synchronization (in the system) are observed at certain levels of excitations.
