Dentre as várias espécies de café, Coffea arabica L. destaca-se pela sua ampla importância comercial relacionada ao consumo da bebida e à produção de óleo. O grão de café possui grande quantidade de compostos fenólicos bioativos - destacando-se os com atividade antioxidante e fotoprotetora - e após a extração do óleo há sobra de grande quantidade de subprodutos, denominado torta. O objetivo desse trabalho é produzir um extrato a partir da torta de café selecionando o melhor solvente extrator, avaliando o teor de compostos fenólicos e o potencial antioxidante, para o emprego como ativo cosmético em formulações desenvolvidas, com análise in vitro para quantificação do Fator de Proteção Solar (FPS) dessas. Os extratos foram previamente produzidos por sonicação utilizando solventes de diferentes polaridades, e o extrato escolhido foi produzido em maior escala por maceração e realizado também extração exaustiva com o solvente escolhido (extrato etanólico 70%, v/v). Na determinação do teor de fenólicos totais foi utilizado o método com o reagente Folin-Ciocalteu. Foi avaliado também o rendimento (m/m) dos extratos e atividade antioxidante pelo método do radical DPPH. O extrato apresentou boa atividade antioxidante e alto teor de compostos fenólicos em comparação com outras plantas consideradas referências nessas propriedades. Para o preparo das formulações foram utilizados matérias primas aprovadas pela ANVISA, e as quantidades dos filtros solares químicos empregados para obtenção de Fator de Proteção Solar (FPS) teórico próximo de 30, utilizou-se como ferramenta o BASF - Sunscreen Simulator. As formulas desenvolvidas e preparadas foram analisadas com o equipamento Optometrics SPF 290S, capaz de fazer a determinação do FPS por análise in vitro. A preparação selecionada foi a que apresentou FPS adequado pela análise in vitro e sensorial mais leve, visto ...

This study aimed to develop, implement and evaluate the performance of a new type of bioreactor for anaerobic treatment of wastewater using different filling materials like trickling filters post-reactor. This bioreactor has mixed characteristics of the UASB reactors and horizontal flow from the point of view of removal of BOD (Biochemical Oxygen Demand) ssed (settled solids), TS (Total Solids), SS (Suspended Solid), SD (Dissolved Solids) and turbidity. The experimental model consists of a bioreactor with a volume of 12 m³, 2/3 filled by fluidized bed and 1/3 for fixed. The fluidized bed is made of polystyrene plates used as a system percolation and compartmentalized trickling filters, where each compartment was filled with a support medium with different characteristics (gravel number 4, plastic rings of polystyrene, PET and HDPE) . In addition, the output of a filter system was installed three entries filled with activated carbon. The bioreactor was installed in private residence in the city of Igarapava-SP (20° 02'40.18"S and 47° 45'01.36" W). The system was highly efficient as the removal of organic contaminant load 92% on average reducing the BOD, a significant result when compared to other anaerobic systems. For the other parameters, the mean reduction was 96% for turbidity, 99% ssed, 67.5% ST, 57% SD and 88% of SS. As for its operation the system was capable of operating in continuous flow without the need for maintenance during the entire period of evaluation and without energy, as it operates taking advantage of the natural slope of the terrain where it is installed. The environmental impacts were minimized due to the preservation of local vegetation allowing the ecosystem to remain unchanged beyond the prototype was completely sealed preventing exhalation of odors and therefore not causing inconvenience to neighboring populations. Given these facts it was concluded that the prototype is shown to be highly feasible deployed as a new alternative for treatment of sewage in rural and urban settings (individual homes, condos, farms, ranches, etc.) Due to ease of design and operability, and sustainability at all stages of execution.

This work aimed to evaluate some aspects of construction and operation of full-scale best management practices and their effects on infiltration loading rate. Two systems were studied: i) filter-swale-trench (FST) and ii) infiltration well (IW). In these units, field essays and full-scale measurements were made in order to assess the soil permeability. Further, the fine particles transportation and the geotextile blanket permeability were determined before and after operation. The results pointed out that there were soil transportation to inside the FST and IW systems, despite of the installed protections, and that these material were responsible for diminishing the geotextile (reduction from 30 to 90% for FST and 40 to 70% for IW) and the full-scale infiltration loading rates (varying from 4,7 x 10-6 to 10-5 m.s-1).

The guidelines of National Curriculum for Dental courses highlights the necessity in providing for the professional the ability to analyze and assess community’s problems and needs, and to create solutions for the society. The continuing education may be considered a useful tool for the teaching and learning because it favors the diversification of learning environments, which allows the insertion of undergraduate and graduate students into the real scenarios. This current study aimed to assess the Public Health projects and programs of the UNESP – Araçatuba Dental School, by describing the interaction experiences between faculty and health services in the professional career development. Historical, documentary and descriptive searches were performed based on the faculty archives such as official documents, reports, databases from the Pro-rector of continuing education and published papers in the period between 1964 and 2011. The following experiences were noted: the Extra-Muro Dental Service (SEMO), established in 1964, that focused in providing dental treatment to the rural population, highlighted the social inclusion of discriminated society groups since that time. In 1972, this service was expanded to several specific populations living in the urban areas. In the '60s, many educational campaigns were performed as homemade water filter and construction of wells and septic tanks which demonstrate the concern with the determinants of healthdisease process. At that time, the campaign of fluoridation of public water supplies in several counties started as Araçatuba, Birigui, Penápolis, Guararapes, Valparaíso and so on. The Campaign of “Good Teeth” from the '70s became wider over time and it was transformed in the "Oral Health Education Program" and it was continuously developed in all public schools of Araçatuba and some neighboring towns, benefiting children aged from 6 to 10 years-old. Several epidemiological studies of caries, periodontal diseases, malocclusion and fluorosis were conducted in cooperation with local governments, and counted with the participation of undergraduate and graduate students. Pereira Barreto – SP was the precursor city in Brazil to carry out fluorosis study. Currently, 12 projects of Public Health from the Institution of Higher Education in the Pro-rector of continuing education are being developed. The concern in qualifying the human resources in health is confirmed with the development of training courses and workshops for professionals, highlighting the training for people enrolled in the Family Health program; Community Health Agent training - Solidarity University, and Municipal Health Counselors training. The Graduate Program in Social and Preventive Dentistry, created in 1993, has an important role to train several professionals for the Unified Health System, and provides education to create researchers, professors and administrators, and enucleates research groups in several Brazilian states. In all activities showed herein, a dynamic participation of undergraduate and graduate students has been observed, and several books, guidelines, articles, brochures and booklets have been published as a result of the continuing education activities.. It was concluded that different projects and programs have been developed by the Public Health of UNESP –Araçatuba Dental School, which allow the exchange of experience between the university and health services, and benefit all participants enrolled in these activities.
