In a concise way, the article reports part of the Master of Arts dissertation in Music entitled The meaning of the teaching of Arts in H. Gardner's perspective, presented in the IAUNESP [Arts Institute-State of Sao Paulo University] in 2008. Some considerations on the Statutory Law n. 11.769/08 were added to the original text. The produced research had an exploratory nature and a theoretical mark. Some texts by Howard Gardner, by the psychologist Eliane Leao, as well as the text of the National Syllabus Parameters-Art, from the Department of Elementary Education, served as a foundation for this article. The intended aim was to demonstrate to what extent the pedagogical proposition of the Arts Education projected by H. Gardner is similar to the one proposed by the National Syllabus Parameters, and which would the benefits be in this age group of an artistic sensitizing work for the development of the individual's personality.

A consequence of population growth is the increased generation of solid waste, which requires environmentally and economically viable suitable disposal sites. The scarcity of such sites makes necessary to adopt non-generation measures, reduction, reuse , recycling and treatment of solid waste before final disposal of waste. This paper presents the quantification and qualification of organic waste generated in each sector of the University Restaurant (UR) , by proposing indicators of waste generation per meal (index of waste) . Then, from the characterization of the waste management practices adopted internally, evaluates the potential deployment of the composting process for organic waste, with signaling for opportunities to improve waste management. The diagnosis of waste generation was made based on data collected during the period of 10 days. The waste were classified into 3 groups (organic, recyclable and waste) in each sector of the restaurant ( pre preparation , kitchen and tray return) . The results reveal that 33 % of the waste generated in the UR currently has the potential to be composted in a suitable place on campus. Every meal served generat approximately 124g of waste, of which 35g are organic waste of the pre preparation sector, 49g are remnants of food in the tray’s return and 40g are other kinds of waste, including recyclable and non recyclable. You can still get a higher percentage of compostable if the trays pre-wash is not performed with detergent and water. To minimize the generation of waste trays can be replaced by plates and skimmers and ladles can be replaced by smaller ones. The food exposed in the counter but not consumed, can be distributed to students after the restaurant is closed so this material would not be disposed in the garbage

Low crystalline PZT powder samples were successfully synthesized using polymeric precursor method and slow decomposition steps. The polymeric resin precursor was thermal treated in a muffle type oven varying the temperature from 250 °C to 700 °C and the time from 3 to 24 hours in order to investigate the order/disorder mechanism toward the amorphous powders. Powder samples with low crystalline phases were obtained at lower temperatures and long time of thermal treatment, demonstrating a kinetic dependence for organic removal and a thermodynamic barrier for crystallization processes. Through XRD and FTIR spectroscopy characterizations the long time thermal treated samples showed to be composed of the solid solution of metal oxides in absent of organic matter, originating broad XRD peaks profiles and no carbonaceous bands in FTIR spectra. A Photoluminescence characterization showed that the peak emission is higher for disordered and homogeneous phases, which only can be reached through the long time of thermal treatment.
