A redução das emissões de gases de efeito estufa representa um grande desafio tecnológico aos modelos industriais vigentes. Mecanismos de Desenvolvimento Limpo (MDL) e sequestro de CO2 fundamentam grande parte dos planos de crescimento sustentáveis, com vistas à obtenção de níveis mais seguros de CO2. Pesquisas promissoras consideram a técnica de sequestro de CO2, por meio da carbonatação mineral, em que silicatos ricos em magnésio, cálcio, ferro e manganês são transformados em carbonatos. Este trabalho teve por objetivo caracterizar, em caráter preliminar e exploratório, as rochas metamáficas e metaultramáficas dos Complexos Amparo e Itapira, com vistas à avaliação de seu potencial mineral para uso em processos de carbonatação mineral no sequestro de CO2; essas rochas constituem terrenos metamórficos de grau médio a alto, localizadas na região de Itapira, Amparo, Serra Negra e Lindóia (SP). As rochas metamáficas reúnem anfibolitos, actinolita xistos e hornblenditos, e encontram-se na forma de lentes ou camadas estiradas em intercalação com rochas supracrustais. As rochas metaultramáficas ocorrem em corpos pequenos e descontínuos, com composição mineralógica em geral rica em olivina, piroxênio e anfibólio. As rochas avaliadas no presente estudo apresentam potencial para carbonatação mineral, em particular aquelas com teores elevados de magnésio. Dessa forma, podem representar importante prospecto de avaliação de jazidas para utilização em processos de carbonatação mineral.

One hundred non-patient dentistry students aged 17 to 25, were interviewed through questionnaire and were clinically examined in order to asses the prevalence and degree of severtty of Craniomandibular Dysfunction, through indeces which are subdivided into three classes: anaminestic index, clinical dysfunction index, and occlusal index. The following variables were introduced to the original indeces: sex, age, and whether the subjects had or had not received orthodontic treatment. The results showed that 42% of the subjects presented mild subjective symptoms whereas, no one showed severe subjective symptoms. Women, as well as the older subjects, showed a higher trend to presenting more subjective complaints. Subjects, whether treated orthodontically or not, showed a similar trend to having dysfunction symptoms. Fifty-six per cent of the subjects presented some score of clinical dysfunction, 25% of them showed moderate or severe clinical dysfunction. Women showed a statistically significant higher index. The older subjects trented to have indeces with more severe degrees. Orthodontic treatment suggested to have no influence on the clinical dysfunction index. Sixty-six per cent of the subjects showed a mild occlusal index and 11% a severe occlusal index. Sex, age, and orthodontic treatment did not show any significant difference as to the presence or absence of malocclusion

The searches for a health service it’s a part of a process, searches for a qualified evaluation can arise the perception, in form of irritating factors taking for an alert state. The personal expectation, it makes influence in its perceptions, too. The objective was to evaluate the satisfaction degree of the users of “Seção Técnica de Ambulatório Geral do Hospital das Clínicas de Botucatu”. The work is about a quantitative and transversal study, with calculated sample of 366 users, chosen randomly and invited to participate through a questionnaire. The population was compounded by a majority of women (64,5%), between 50 to 59 years old and average degree of education (38,3%). 25 specialties were cited. The evaluate about comfort, cleaning, reception, waiting time, medical attention and nursing vary between “very good” and “good”. Obtained significant “regular” assessment, the comfort in the waiting rooms (24%), silence (25%) and cleaning bathroom (63%). Others negative evaluation was the reception about the waiting time (26%), waiting time between arrival and the consultation (34%), waiting time between the request and consultation (27%). 30,6% report to know the place for complaints and 79,4% of these pointed to the ombudsman. 62% consider their problems solved, 84,4% would indicate the hospital, 57,4% would consider the hospital better than imagined. 42,62% used the opened area for thanking, critical for staff, suggestion infrastructure improvements, cleaning and waiting time. The biggest complaint was the staff turnover in the treatment. There was disharmony between the objective and subjective questions, but, all of them must be considered to propose improvements. The satisfaction evaluation makes the service more effective, bringing credibility to the health service and the patients adhere better to the treatment
