Chemical composition, proteolysis and functional properties of commercial Mozzarella cheese with reduced fat content found in the market of Londrina – PR were evaluated. The cheeses were analyzed for chemical composition, meltability, free oil formation, and the indexes of extension and depth of proteolysis during 30, 45 and 60 days of storage at 5°C. The samples showed no significant difference in chemical composition. The fat content of all samples complied with current legislation regarding the minimum percentage (25%) of fat reduction. Among the three brands tested, the cheeses of brand C showed the highest depth index of proteolysis. In all chesses, the meltability has increased during storage period. The, the brand C had significantly higher (p <0.05) free oil content when compared to other brands tested.

Climate variability and therefore the rainfall is often cited today, in times to speak of "global change", "global warming", "anthropogenic disasters," among other terms related to climate issues, which may cause floods and disasters that affect entire regions. In this sense, the seasonal rainfall and its extremes in the basin of Ivaí river, which has a drainage area of approximately 36 000 km2, covering a length of 680 km, located in the State of Paraná between coordinates 22 º 54'S 25 ° 44'S and 55 44'W to 52 º 42'W, were analyzed. Influence of rainfall for the man occupation is undeniably important, not less important is the role that this issue poses to the climate abiotic and biotic environment, because the dynamic relations between the fauna and flora is directly related to the availability of water in system (in this case, rain). The methodological procedures used during the research focused on statistical analysis of rainfall series daily, monthly and yearly, provided by the Superintendence of Water Resources Development and Environmental Protection Agency - SUDERHSA, an agency linked to the government of Parana. The analysis period chosen was from 1975 to 2005, with 38 stations for data collection, distributed evenly across the search area. The standard rainfall in the basin is explained mainly by convective processes in the summer (wet season) and front system causing more homogeneous rainfall over the basin (dry season). What is well marked is the occurrence of maximum rainfall in the years 1983 and 1997 (El Niño) and minimal in the years 1977, 1985 and 1988 (La Niña). Finally, although the study area have undergone a significant change in your landscape for over thirty years, this study indicates no significant interference in rainfall.

A energia eólica é uma forma de energia que seu uso encontra-se em expansão, e junto a esse crescimento, tem-se também o aumento da quantidade de resíduos gerados na fabricação das pás eólicas. Uma forma correta de destinação e aproveitamento desses resíduos é a reciclagem. Porém, esses são constituídos de materiais compósitos, geralmente a resina epóxi e a fibra de vidro; e por possuírem um polímero termofixo (a resina epóxi) na sua composição, a reciclagem convencional via fusão não é possível. Desta forma, a reciclagem química via pirólise apresenta-se como uma alternativa para o aproveitamento desses resíduos, em especial da fibra de vidro que o contém. Após caracterização do resíduo de uma indústria de pás eólicas, verificou-se que se tratava de um material com mais de 70% de fibra de vidro e muito densas. Foram realizados ensaios de pirólise a seco e com óleo de babaçu, considerado o mais interessante perante vários possíveis e no qual o resíduo fica totalmente imerso, facilitando o inchamento e a troca de calor. Em um sistema de aquecimento com vácuo, foram obtidas mais de 97% de fibras em 30 minutos a 310 oC, justamente a temperatura em que uma análise termogravimétrica apontou ser a de início de altas taxas de degradação térmica.

This article presents considerations concerning the interaction between communication and digital platforms and applications developed to perform computerized climate monitoring and issue alerts about natural disasters. From work in the Center for Integrated Natural Disaster Alert (CIADEN), which processes meteorological data provided by Platform Monitoring, Analysis and Warning TerraMA2 designed by the National Institute for Space Research (INPE) to conduct monitoring and fi ring warning about climate risk environment, we propose the expansion of interactivity with the various possibilities of digital communication available today for signifi cant portion of society. On another front, the CIADEN has articulated teaching and research on climate monitoring and warning of natural disasters, weather, and geoprocessing environment, involving teachers and students both in school and in higher and technical.
