The research objective was to examine the perspective of professionals, the major communication barriers experienced during the Accreditation process in a medium sized private hospital in Belo Horizonte. This is a qualitative study involving 34 health professionals from different categories. The survey results showed that the shortage of information, lack of objectivity, integrity and explicitness in the transfer of knowledge favors the rupture of the provision of quality services. The organizational communication is an effective tool to support major changes in companies, as it is the scope of hospital accreditation. Articulating the change in a concise manner, with focus on the communication, can be achieved the quality standard. Source

The campos rupestres and the campos de altitude from eastern Brazil occur in the mountaintops of the Espinhaço Range, Serra da Mantiqueira and Serra do Mar. Since there is some confusion on the characterization and about geographical limits of both vegetation types, the aim of this paper is to present a review of opinions about on those open environments, with discussions on the history of their nomenclature, physiognomic aspects and biogeographical affinities. Although the campos rupestres and the campos de altitude present some physiognomic and floristic similarities, both should be considered distinct vegetation types. Source

In this paper the characteristics of fodder radish, a potential biodiesel source, are investigated. Recent developments in fodder radish biodiesel production and studies on the composition of fodder chemical structure are reviewed. The physical-chemical characteristics of fodder radish crude oil and biodiesel were measured and compared with available literature data and biodiesel specifications. The measured properties were density, kinematic viscosity, carbon residue, sulfur content, acid number and iodine value. A thermogravimetric analysis to evaluate the thermal behavior of fodder radish crude oil and biodiesel is included. The results show that fodder radish biodiesel can meet physical-chemical property specifications, although its acid number requires attention. © 2012 Elsevier B.V. Source

The effects of diesel oil-soybean biodiesel blends on a passenger vehicle exhaust pollutant emissions were investigated. Blends of diesel oil and soybean biodiesel with concentrations of 3% (B3), 5% (B5), 10% (B10) and 20% (B20) were used as fuels. Additionally, the effects of anhydrous ethanol as an additive to B20 fuel blend with concentrations of 2% (B20E2) and 5% (B20E5) were also studied. The emissions tests were carried out following the New European Driving Cycle (NEDC). The results showed that increasing biodiesel concentration in the fuel blend increases carbon dioxide (CO2) and oxides of nitrogen (NOX) emissions, while carbon monoxide (CO), hydrocarbons (HC) and particulate matter (PM) emissions are reduced. The addition of anhydrous ethanol to B20 fuel blend proved it can be a strategy to control exhaust NOX and global warming effects through the reduction of CO2 concentration. However, it may require fuel injection modifications, as it increases CO, HC and PM emissions. © 2010 Elsevier Ltd. All rights reserved. Source

Fuel consumption and cold start characteristics of a production vehicle fuelled with blends of N. 2 diesel oil (500 ppm sulfur content), soybean biodiesel (3%, 5%, 10%, and 20%) and hydrous ethanol (2% and 5%) were compared. A wagon-type vehicle equipped with a four-cylinder, 1.3-l, 63 kW diesel engine was tested in a cold chamber at the temperature of -5 °C for the cold start tests. Fuel consumption tests were performed following the 1975 US Federal Test Procedure (FTP-75). The results showed that the cold start time was satisfactory for all fuel blends tested, but it was longer for the blend containing 20% of soybean biodiesel (B20) in comparison with the blends with lower biodiesel concentration. The cold start time also increased with increasing with increasing ethanol content in the fuel blend. Specific fuel consumption was not affected by increasing biodiesel concentration in the blend or by the use of 2% of ethanol as an additive. However, the use of 5% of ethanol concentration in the B20 blend resulted in increased specific fuel consumption. © 2011 Elsevier Ltd. All rights reserved. Source
