Though urban form affects the thermal environment, there are only a few legal tools that include the thermal issue in the city planning and urban design. This research established a link between urban form and thermal environment, by considering urban indexes such as the occupation coefficient, the floor space index and the vegetation cover index, to characterize the land use and occupation. For this purpose, the study area was an urban fraction of the Brazilian city of São Carlos, in State of São Paulo. Several points of the study area were taken as references for thermal measurements, while others regional data of the climate were registered by the meteorological station situated in the city skirts. The data were collected in periods representing dry weather of winter months. The measurements allowed the validation of a computational model applied for microclimatic simulation of the urban area - the ENVI-met. The best situation performed by the model was determined by comparison of real and simulated data. This process allowed data extraction by simulation of the whole area and the development of thermal maps, considering the real urban situation, a scenario of densification and a scenario of green areas. The results pointed out that the rise of the occupation coefficient causes a slight elevation of the air temperature. Even more significant tendencies were also assessed by the development of a multiple regression model, revealing the potential of the floor space index, the urban green cover and their association with the wind speed.
Restrições ao uso de sistemas de medição de desempenho em pequenas e médias empresas: estudo de campo em indústrias de transformação do setor metal-mecânico

The Performance Measurement System (PMS) are one of the essential tools to withstand the demands of information at all levels within an organization, and also is an important means of measuring the effectiveness of their business strategy. However, due to several peculiarities present in Small and Medium Enterprises (SME), this tool is not always implemented and used in full. Given the above, this work aims to identify constraints that make it difficult the implementation and use of a PMS in SMEs. For this, a literature search and also a survey research was conducted, covering a unit of analysis of 21 industries in the metal-mechanical sector. This research was conducted in the region of Limeira, an important industrial center, located within the São Paulo state. As a result, it was found that SMEs face many difficulties in implementing PMS and this phenomenon is due to the fact that SMEs have characteristics that differ from large companies. Factors such as lack of resources, excessive informality, lack of a strategic long-term vision and lack of knowledge of this tool have been identified as existing in most of the surveyed companies. These factors added the characteristics of business, become serious constraints to the development and use of this tool.
Estrutura da ictiofauna e ecologia trófica de Sciaenidae acompanhante na pesca do camarão sete-barbas, no litoral de Santa Catarina, Brasil
(Universidade Federal de São Carlos, 2014-06-13) Sabinson, Lia Mayrink; Verani, José Roberto; https://lattes.cnpq.br/0053232138684810; https://lattes.cnpq.br/8836864670457648
In trawling a significant portion of the captured fauna has no commercial value and is returned to the sea, causing biological and ecological changes, with impacts on the food chain, modifying processes of energy transfer in the ecosystem. Studies on the feeding habits of demersal fish provide basic information for understanding species trophic relations. Thus, this work aimed the undestandment of the feeding habits of the most abundant fish present in the bycatch of the Xiphopenaeus kroyeri artisanal fisheries of the coast of Santa Catarina, through the analysis of stomach contents, describing patterns of similarity, overlap and trophic structure. Sampling took place seasonally, from November 2009 to August 2010, in Balneario Barra do Sul, Porto Belo and Penha. Whaling vessels from the artisanal shrimping fleet were used for trawling. After sorting the specimens, they were frozen until the completion of biometrics and stomach content analysis. Information obtained through analysis of stomach contents were quantified via the Kawakami-Vazzoler feeding index, combining the frequency of occurrence and the relative volume of the items. Species of Sciaenidae family were the most abundant. Ctenosciaena gracilicirrhus, Cynoscion jamaicensis, Larimus breviceps, Menticirrhus americanus, Stellifer brasiliensis and S. rastrifer were classified as crab eaters, while Isopisthus parvipinnis crab eater/piscivore, Micropogonias furnieri as annelid eater/crab eater and Paralonchurus brasiliensis as annelid eater, however species were found to have very similar diets, altering the intake of certain items between seasons and locations. According Morisita overlap index, 9 cases of overlap were observed in Balneario Barra do Sul, 9 in Penha and 20 in Porto Belo. The bipartite foodwebs showed generality in the intake of food, with most species carrying multiple trophic interactions. Once the Sciaenidade family is the most abundant and diverse in the sea-bob-shrimp bycatch, iv its removal seems to directly influence the ecosystem processes in the region, with most species performing a wide range of interactions. Therefore their removal will gradually change the stability of benthic community.
