O livro apresenta os resultados mais relevantes das atividades realizadas dentro do Programa de Pesquisa sobre Mudanças Climáticas Globais, patrocinado pela Fapesp e relacionado a estudos de impactos, vulnerabilidades e variabilidades nas mudanças do clima no estado de São Paulo e região sudeste do Brasil. Tais experiências têm sido discutidas e desenvolvidas com grupos de pesquisa de Portugal, que dão ao trabalho um caráter mais abrangente e internacional. O Brasil vem estudando já há algum tempo impactos das mudanças no clima que possam servir como base para estratégias de adaptação e para análises de vulnerabilidade diante das ameaças climáticas. O projeto da Fapesp tem, especificamente, a missão de produzir estudos de detecção e traçar cenários climáticos futuros, com metodologias que possam ser aplicadas em todo o Brasil. Essa metodologia leva em conta uma combinação de dados do clima (observações e projeções derivadas de modelos climáticos) com base em informações ambientais, geográficas, geofísicas e sociais. A ênfase está nos extremos climáticos e nos seus impactos sobre os recursos hídricos, assim como no planejamento com vista a minimizar os desastres naturais de origem meteorológica, que de alguns anos para cá têm se disseminado pelo país

Because of the great metallurgical advances, the welded tubes by HF / ERW (High Frequency / Electrical Resistance Welding) have played a more active role in the oil and gas, gradually replacing tubes produced by other processes (UOE, SAW, and others) to deep water applications, in high and extremely low temperatures, highpressure conditions and in highly corrosive environments. However, studies have revealed that defects in the welded joints are in one of main causes of failures in pipelines. Associated with damage external and the stringent requirements of this sector, the welded joints become particularly critical for his toughness and the determination of this particular property is fundamental. This study aims to evaluate the toughness of the HF / ERW pipes in HSLA steel API X70 class, used in pipelines transport systems of gas and oil from data obtained with CTOD tests (Crack Tip Opening Displacement). The main objectives of this project are: mechanical and microstructural characterization of steels API X70 manufactured in Brazil; and evaluation of the toughness of weld process by HF / ERW steel API X70 national. After having the tests done, mechanical, chemical and metallurgical, we have the conclusion that those pipe are in agreement to API 5L 42ª edition for X70MO and the toughness behaves like the expected

The purpose of this work was the inlay’s characterization from the water supply networks of Rio Claro-SP city; as well analyze the influence of network’s aging in the actual system. To do this, some samples of inlays were collected and made chemistry analysis and X-Ray Diffraction Spectrometry. The history of the source water quality was also analyzed, to make possible to known the origins of the inlays. To evaluate the performance of the network, some different scenarios have been simulated, varying the resistance coefficient of the water supply networks of Rio Claro-SP. The characterization results showed that there are basically oxide and hydroxide of iron (magnetite and goethite) and quartz in the inlays, which are materials of high hardness. The hydraulic simulations indicated that the simulated scenarios had a variation of ~2000% in terms of loss of energy

The present work aims to expand and contribute to the understanding of issues related to social demands urgent today as regards of teachers’ formation of kindergarten and initial series. Through a survey of the profile of students in four years (2007-2010) of Pedagogy, UNESP, Bauru, I propose to trace discussions about the student profile that seeks to train teacher in higher education. This process will reveal the profile of the student who is preparing to enter the teaching profession and who in later years will work in public and private spheres of education as a teacher, coordinator and manager in the kindergarten and elementary education. For this research will develop both qualitative approach in that it analyzes the profile to the light of the literature and studied quantitatively the extent that is based on the results

The pharmaceutical innovations, such as the use of polymers to control drug release, create possibilities for a better action of the drug in the body, which causes a a more effective therapeutic effect and a safer treatment for the patient. In this work, were prepared and characterized matrix tablets of hydroxypropylmethylcellulose (HPMC) containing nimesulide as model drug to evaluate the performance as a controlled release system. HPMC, a cellulose ester, is a hydrophilic polymer that undergoes swelling, i.e., absorbs water and forms a gel layer controlling drug release. The characterization of powders was performed by analysis of particle size and morphology, density, compressibility index determination, flow properties and determination of swelling profile. The tablets were evaluated according to their physical parameters of quality and to the in vitro release of nimesulide, as well as the analysis of the mechanisms of drug release by appropriate mathematical models. The set of results showed that the HPMC/Nimesulide mixture exhibited satisfactory physical characteristics (size, shape, density and flow). The release profile demonstrated an effective control upon drug release in enteric environment and presented more correlation with Korsmeyer-Peppas’ and Weibull’s mathematical models, indicating that the release of nimesulide occurs through the relaxation of the polymer chains
