OBJETIVO: Avaliar o índice de qualidade da dieta de adolescentes residentes no Distrito do Butantã do município de São Paulo, SP. MÉTODOS: Estudo transversal de base populacional com uma amostra de 437 adolescentes, de ambos os sexos, com idade entre 12 e 19 anos. Foram obtidas amostras probabilísticas em dois estágios, setor censitário e domicílio, da área estudada. O consumo alimentar foi medido pelo método recordatório de 24 horas e a qualidade da dieta avaliada pelo Índice de Qualidade da Dieta adaptado para a realidade local. RESULTADOS: Dos adolescentes avaliados, 4% apresentaram dieta saudável, 68% dieta que necessita de melhora e 28% dieta inadequada. O sexo masculino apresentou maior pontuação para os componentes do Índice de Qualidade da Dieta cereais, hortaliças, leguminosas e variedade da dieta. O aumento no número de anos de estudo do chefe da família apresentou-se associado ao maior consumo dos grupos de alimentos: cereais, verduras e legumes, leite e produtos derivados e variedade de alimentos; a relação foi inversa para o grupo de leguminosas e sódio. CONCLUSÃO: A maioria dos adolescentes estudada não segue as recomendações dietéticas preconizadas, fato que pode comprometer a saúde futura desses indivíduos.

Residual signal auto-correlation to evaluate speech in Parkinson's disease patients

Objective: To evaluate the maximum residual signal auto-correlation also known as pitch amplitude (PA) values in patients with Parkinson's disease (PD) patients. Method. The signals of 21 Parkinson's patients were compared with 15 healthy individuals, divided according age and gender. Results: Statistical difference was seen between groups for PA, 0.39 for controls and 0.25 for PD. Normal value threshold was set as 0.3; (p <= 0.001). In the Parkinson's group 80.77%, and in the control group only 12.28%, had a PA < 0.3 demonstrating an association between these variables. The dispersion diagram for age and PA for PD individuals showed p=0.01 and r=0.54. There was no significant difference in relation to gender and PA between groups: Conclusion: the significant differences in pitch's amplitude between PD patients and healthy individuals demonstrate the methods specificity.-The results showed the need of prospective controlled studies,to improve the use and indications of residual signal auto-correlation to evaluate speech in PD patients.

Biossorção de cobre, manganês e cádmio por biomassas de Saprolegnia subterranea(Dissmann) R.L. Seym. e Pythium torulosumCoker & P. Patt. (Oomycetes)

Dried biomass of the zoosporic fungi Saprolegnia subterranea and Pythium torulosum was evaluated for copper, manganese and cadmium biosorption from aqueous solutions using the "q" (mg of adsorbed metal per g of biomass) and the "R%" (percent removal) indices. The highest q values were observed when the biomass was placed in contact with high metal concentrations, whereas the highest R% values were observed at low concentrations (p< 0.05). S. subterranea SPC 1244 biomass surpassed the others for copper biosorption (q = 7.48 mg/ g; R% = 49.03), P. torulosum SPC 1425 biomass was the best for manganese biosorption (q = 4.13 mg/g; R% = 26.71), and S. subterranea SPC 1431 biomass was the best for cadmium biosorption (q = 6.75 mg/g; R% = 42.26). This is the first report on copper, manganese and cadmium biosorption by the biomass of these zoosporic fungi, indicating the potential to remove ions from diluted solutions.

Spider assemblages in widely-separated patches of cerrado in São Paulo State, Brazil.

Brazilian cerrado is a biologically-rich, poorly understood, yet rapidly disappearing habitat. Composition of the spider assemblages from areas of cerrado from three separate sites in the State of São Paulo, Brazil were sampled by beating the canopies and adjacent shrubs of three Myrcia (Myrtaceae; "myrtle") tree species. These produced a total of 859 spiders 'belonging to 21 families and 75 species. The most undisturbed and densest cerrado habitat had the largest number and greatest diversity of spider species, encompassing stalkers, ambushers, space web-weavers, and foliage runners. The other two areas were dominated by foliage runners. Spider distribution in this natural and complex habitat was evaluated by classifying the samples into 12 habitat/microhabitat groups according to local of the patch, tree species, and microhabitat (target tree or adjacent shrub). Correspondence analysis was used for ordination of species and groups based on their abundance. Environmental factors such as patches type (p=0.027) and plant species (p=0.046) had significant effects in explaining the ordination. Canonical correspondence analysis was applied for relating the patterns in species richness and/or abundance to the significant environmental factors. A comparison of the results showed that the family composition among the patches is rather similar, and there is a tendency of spiders species overlap an interregional level (patches effect, p=0.027). However, the most similar spider assemblages living on woody vegetation occurred in Myrcia venulosa and Myrcia guianensis at São Carlos and Pirassununga, demonstrating an interregional similarity (plant species effect, p=0.046) that indicates an association between spiders and particular vegetation.

Desenvolvimento vegetativo de quatro espécies de grama irrigadas com efluente doméstico

This research aimed to compare the development of four grasses species irrigated by dripping with an effluent from a domestic wastewater station treatment in a small rural community, and supply water from Sabesp. For this purpose, an experiment was conducted in a greenhouse at the FCA/UNESP (Botucatu - SP) for 12 months in a completely randomized 4 × 3 factorial design, with four replications, totalizing 48 parcels. Grass species used in this experiment were: Santo Agostinho (Stenotaphrum secandatum (Walt.) Kuntze); Bermudas (Cynodum dactylon); Esmeralda (Zoysia japônica) and São Carlos (Axnopus sp). The treatments were: T1- Irrigation with re-use; T2- Irrigation with re-use + chemical fertilization and T3- Irrigation with supply water from Sabesp + chemical fertilization (control). Data were submitted to comparison of means by Tukey's test at 5 %. The results showed that nitrogen in the wastewater was enough for the good development of the grass species. However, its use caused higher potassium loss.

Uso de Dois Espaçamentos Entre Gotejadores na Mesma Linha Lateral e Seus Efeitos Sobre a Formação do Bulbo Molhado no Solo e Parâmetros Físicos de Rabanete

The use of irrigation systems that consume lower water and energy in agriculture is important to supply the growing global demand for food. In this way, it's important to develop techniques that will increase the uniformity of water application on drip irrigation systems. The aim of the work was to compare the provision of lateral lines in drip irrigation, through the formation of wet bulbs in soil and physical parameters of radish, composed of single spacing between drippers in relation to lateral lines composed of two segments, each one composed by different spacing between emitters. Two distributions of evaluation were carried out: 1) conventional drip lateral lines with 20 cm emitter spacing were compared to proposed drip lines, with 24 emitter spacing in the initial section and 20 cm emitter spacing in the final section; 2) conventional drip lateral lines with 30 cm emitter spacing were compared to proposed drip lines, with 36 emitter spacing in the initial section and 30 cm emitter spacing in the final section. The experiment was carried out in a greenhouse of the Sao Manuel Experimental Farm, located at Sao Manuel, SP. The experimental design was entirely randomized, with six treatments and four replications. Results showed no difference among treatments for the most of the evaluated variables. So it is possible to conclude that the use of different spacing between emitters in the same lateral line can be used to increase the line length.

Efeito do manejo e de níveis de lodo de esgoto na fertilidade do solo após tres aplicações

The agricultural use of sewage sludge as organic fertilizer is considered nowadays as on alternative of disposal, in the end of the residue in addition to possible environmental problems, it's using can decrease the mineral fertilizers and avoid provide organic matter to the soil. The objective of this study it was to evaluate the parameters of soil fertility under different managements and doses of sewage sludge after the third application of the residue. The experiment was carried out in São Manuel - SP, with the cultivation of sunflower in two consecutives cycles, followed by wheat and triticale without application of the residual, and in the following year with the application of sewage sludge and cultivated the black oats. It was adopted a randomized complete block design, consisting of six treatments and five repetitions defined as follows: T0 - without fertilization; T1 - mineral fertilizer nitrogen according to crop need, T2 - 50% of N from sewage sludge and 50% in mineral form, T3 - 100% of N from sewage sludge, T4 - 150% of N from sewage sludge, T5 - 200% of N derived from sewage sludge. Soil samples were collected in the end of the trial of oats. There were an increase in the levels of P, H + Al, CEC and OM, B, Cu, Fe, Mn, Zn as a function of increasing dose of sewage sludge. To V% and pH were decreased the values in the proportional soil to the increase of sludge dose until 24 and 22 t ha-1, respectively and after increasing the pH and V%.
