Microalgae offer great potential as a third-generation biofuel feedstock, especially when grown on wastewater, as they have the dual application for wastewater treatment and as a biomass feedstock for biofuel production. The potential for growth on wastewater centrate was evaluated for forty microalgae strains from fresh (11), brackish (11), or saltwater (18) genera. Generally, freshwater strai...

The aim of this study was to design ergonomically improved shift schedules for nurses in primary health care shift work in order to enhance their health and well-being. The main change made was the reduction of quick returns (i.e., no more morning shifts immediately after an evening shift) in order to ensure more recovery time between work shifts. Six municipal hospital units participated in th...

We compared the avifauna recorded in a recent survey in an urban park (Parque Municipal Henrique Luís Roessler, Parcão) and surroundings, Novo Hamburgo, RS, with past data, to evaluate the possible alterations in species composition over time. Of the 265 species compiled as original elements of that region, 114 were found at Parcão. Among forest species, 37% were considered locally extinct. The...

Since the Industrial Revolution, livestock has been driven out of urban and semi-urban areas in the United States. Recently, calls for localizing the food system have led to a rise in urban agriculture, and livestock is finding its way back into the city. The return of livestock to urban areas is rife with tensions, including concerns about public health and challenges to dominant perspectives ...

In this paper we have highlighted three things. First, that public organizations are engaged in a technologically driven servitization of their traditional service products. Second, that public organizations must approach this servitization differently because of the decision-making role of citizens in the process. Third, it is essential to study the influence citizens have on this process thro...

Community networks emerged in North America during the late 1970s and early 1980s. During the past three decades, paradigms for networked information, services, and collaboration as resources for community development have evolved in many respects. In this paper we revisit a theoretical analysis of broadband Internet community networks [Carroll, J.M., Rosson, M.B., 2003a. A trajectory for commu...

This study was carried out in the Parque Municipal das Araucárias, in the municipality of Guarapuava, southern Brazil. A total of 449 T. lactitarse nests were collected using trap-nests of different diameters. Fifty three species of spiders belonging to 7 families were captured by T. lactitarse. Araneidae was the most captured family and has been strongly represented by the genus Eustala. Throu...

In 1982 Boyce and Causey reported in Infection Control the results of a survey conducted to determine the magnitude of methicillin-resistant Staphylococcus aureus (MRSA) infections in the United States. From responses to that questionnaire, it was apparent that the number of hospitals reporting MRSA dramatically increased from 1975 to 1980, that larger hospitals were encountering the problem mo...

This paper presents an overview of current solid waste management practices in Kohima, Nagaland, India and suggests solutions to some of the major problems. The levels of socio-economic development determine the quantity and composition of solid waste. Higher the level of economic development, greater the proportion of waste composition. The total population of the city is 1,32,836, among those...

There is mounting evidence that urban areas influence biodiversity. Generalizations however require that multiple urban areas on multiple continents be examined. Here we evaluated the role of urban areas on avian diversity for a South American city, allowing us to examine the effects of urban features common worldwide, using the city of Valdivia, Chile as case study. We assessed the number of b...
