The cultivation of microalgae biomass in order to produce biodiesel arises as an extremely promising aspect, in that the microalgae culture includes short cycle of reproduction, smaller areas for planting and residual biomass rich in protein content. The present dissertation evaluates the performance and features, through spectrometry in the region of infrared with transformed Fourier (FTIR) and spectrometry in the region of UVvisible (UV-Vis), of the extracted lipid material (LM) using different techniques of cell wall disruption (mechanical agitation at low and at high spin and agitation associated with cavitation). The technique of gas chromatography (GC) brought to light the success of alkaline transesterification in the conversion of oil into methyl monoesters (MME), which was also analyzed by spectroscopic techniques (FTIR, proton magnetic resonance (1H NMR) and carbon (13C NMR). Through thermogravimetric analysis (TGA) were analyzed the lipid material (LM), biodiesel and the microalgae biomass. The method which provided the best results concerning the efficiency in extraction of the LP of Monoraphidium sp. (12,51%) was by mechanical agitation at high spin (14 000 rpm), for 2 hours being the ideal time, as shown by the t test. The spectroscopic techniques (1H NMR, 13C NMR and FTIR) confirmed that the structure of methyl monoesters and the chromatographic data (CG) revealed a high content of saturated fatty acid esters (about 70%) being the major constituent eicosanoic acid (33,7%), which justifies the high thermal stability of microalgae biodiesel. The TGA also ratified the conversion rate (96%) of LM into MME, pointing out the quantitative results compatible with the values obtained through GC (about 98%) and confirmed the efficiency of the extraction methods used, showing that may be a good technique to confirm the extraction of these materials. The content of LM microalgae obtained (12,51%) indicates good potential for using such material as a raw material for biodiesel production, when compared to oil content which can be obtained from traditional oil for this use, since the productivity of microalgae per hectare is much larger and requires an extremely reduced period to renew its cultivation

OBJETIVO: Estudar a ocorrência dos erros refracionais em escolares de nosso meio. MÉTODOS: Estudo transversal avaliando crianças da pré-escola e do ensino básico, quanto ao sexo, tipo de erro refracional, acuidade visual e tratamento realizado. RESULTADOS: Quatro mil seiscentos e vinte e três crianças foram submetidas a exame de acuidade visual, das quais 8,1% apresentaram necessidade de exame oftalmológico completo. Houve 63,2% de portadores de astigmatismo hipermetrópico, 15,7% de astigmatismo miópico, 12,5% de astigmatismo misto, 4,9% de hipermetropia e 3,7% de miopia. Foi indicada a prescrição de lentes corretoras para 48,7% da amostra estudada. A frequência de erros refracionais na população foi de 3,9%. CONCLUSÃO: O astigmatismo hipermetrópico foi o erro de refracional mais frequente, havendo necessidade de tratamento em cerca de 50% das crianças triadas com frequência de 3,9% de erro refracional passível de correção na população de estudo.

Purpose: To describe the implantation of the red reflex test in 30 cities in the area of Botucatu Medical School Clinical Hospital, (480,337 inhabitants) and the creation of a reference Center for children with red reflex changes, the Red reflex screening and another Center for treatment of childhood cataract.Methods: The red reflex exam was released in 30 cities of the surrounding Botucatu area, lectures were done in the cities invited to participate by the Regional Department of Health. 109 pen torch ophthalmoscopes were distributed to the hospital maternities and primary care units. The Red reflex screening attended cases of altered or doubtful red reflex and established the diagnosis. The Center for treatment of childhood cataract performed the preoperative examination, surgical treatment and follow-up of children with cataracts.Results: After one year the Red reflex screening attended 29 children, 17 males and 12 females, mean age and pattern deviation (PD) of 10.09 +/- 20.35 months (7 days - 98 months old). 16 patients were referred with altered red reflex, with a mean age and pattern deviation of 13.17 +/- 24.14 months (7 days - 98 months old). The alteration was confirmed in all of these cases. 13 children had cataract. In 13 children with doubtful exam, with a mean age and PD of 6.29 +/- 14.46 months (7 days - 54 months old), the alteration was not confirmed in any of these patients. The incidence of negative red reflex found among newborns was 9.2/10,000 and the incidence cataracts in this same group was 7.9/10,000.Conclusion: We described the implantation of the red reflex exam in the Botucatu area, and the creation of a reference Center for eye examination of children with changes in the red reflex, and the creation of a reference Center for treatment of childhood cataract and difficulties.

Objetivo: Identificar os microrganismos da conjuntiva ocular de cães clinicamente sadios na região de Araçatuba (SP), no verão e no inverno. Métodos: Foram utilizados quarenta cães, machos e fêmeas, com idade variando entre 2 e 5 anos. Após limpeza ocular com água tratada, foram realizadas colheitas de material do saco conjuntival inferior com auxílio de swabs estéreis, para posterior isolamento e identificação de bactérias aeróbicas, anaeróbicas e fungos. Resultados: As bactérias de maior ocorrência foram o Staphylococcus aureus e o Staphylococcus beta-haemolyticus. O fungo de maior ocorrência foi Penicilium sp. Conclusão: Pôde-se concluir que houve variação da microbiota conjuntival normal em função da estação do ano. Dos microrganismos isolados, o único que apresentou diferença estatística significativa quanto à incidência sazonal foi o Staphylococcus beta-haemolyticus, que foi isolado apenas no inverno.
