Abstract: A procura por alimentos funcionais, como leites fermentados com culturas microbianas probióticas, aumentou o interesse em pesquisas para manter estes micro-organismos viáveis no produto. Neste sentido, o objetivo deste trabalho foi formular um leite fermentado sabor morango agregado de benefícios potencialmente prebióticos e probióticos, apresentando características sensoriais adequadas. Um planejamento fatorial 23 com ponto central foi realizado para otimizar a saboriza o do produto, avaliando a adi o de sacarose (50, 85 e 120 g.L-1), corante natural carmim cochonilha (0,5; 1,0 e 1,5 g.L-1) e aroma natural de morango (0,10; 0,25 e 0,40 g.L-1). Diferentes concentra es da cultura Bio Rich (L. acidophilus, Bifidobacterium e S. thermophilus) foram testadas (1,00; 0,50 e 0,33 g.L-1), ordenando-se sensorialmente conforme a preferência. Concentra es do xarope de fruto-oligossacarídeos (50 e 100 g.L-1) foram avaliadas por meio de aceita o sensorial e análises microbiológicas. Um leite fermentado sabor morango utilizando, em g.L-1, 0,33 de cultura, 120 de sacarose, 1,5 de corante, 0,4 de aroma e 100 de xarope de fruto-oligossacarídeos, foi desenvolvido. O incremento da concentra o de prebiótico influenciou positivamente na preferência do produto, apresentando índice de aceita o de 88%; microbiologicamente, aumentou a contagem de L. acidophilus e Bifidobacterium, sendo 1,7 × 10(7) e 4,8 × 10(6) UFC.mL-1, respectivamente, com 100 g.L-1 de prebiótico. The demand for functional foods, including milk fermented with probiotic microbial cultures, has increased the interest in research to maintain these microorganisms viable in the product. Thus the objective of this work was to formulate strawberry flavoured fermented milk with added potentially beneficial prebiotics and probiotics, and with suitable sensory characteristics. A 23 experimental design was used to optimize the product flavour, evaluating the addition of sucrose (50, 85 and 120 g.L-1), the natural dye cochineal carmine (0.5, 1.0 and 1.5 g.L-1) and a natural strawberry aroma (0.10, 0.25 and 0.40 g.L-1). Different concentrations of Bio Rich culture (L. acidophilus, Bifidobacterium and S. thermophilus) were tested (1.00, 0.50 and 0.33 g.L-1) ranking the products in according to sensory preference. Two fructo-oligosaccharide syrup concentrations (50 and 100 g.L-1) were evaluated according to their sensory acceptability and microbiological analyses. A strawberry flavoured fermented dairy beverage was developed using (g.L-1) 0.33 culture, 120 sucrose, 1.5 dye, 0.4 aroma and 100 fructo-oligosaccharide syr

Abstract: purpose: to evaluate the prevalence of retinopathy of prematurity (rop) in newborns, classify the cases, describe the risk factors for disease and treatment. methods: a retrospective observational cross-sectional study including newborns with gestational age < 32 weeks and/or weight < 1,500 g admitted to the neonatal intensive care unit of the hospital de clínicas, universidade federal de uberlandia (hc-ufu) during the period of july 2005 to june 2007. results: we analyzed 148 patients. in 66 (44.6%) rop was detected; 82 (55.4%) showed no disease. the statistically significant risk factors were: birth weight (p=0.0001), gestational age (p=0.0001), mechanical ventilation (p=0.0001), blood transfusion (p=0.0001), and postconceptional age (pca) (p=0.0001). of the 66 premature infants with rop, 77% were treated medically (follow-up with indirect ophthalmoscopy) and 23% required surgical treatment or photocoagulation. conclusion: based on the data above, the prevalence observed in this study was high. the development of rop was inversely proportional to the weight and gestational age at birth.
O planejamento estratégico municipal como instrumento de gest?o em cenários complexos: um estudo sobre os condicionantes dos planos da Cidade de Barcelona
Fernandes, Janaína de Mendon?a;
Cadernos EBAPE.BR , 2009, DOI: 10.1590/S1679-39512009000200009
Abstract: this work is an exploratory study on the conditions that led to the adoption and perpetuation of the planning process of the city of barcelona. we checked the political, historical and social constraints as well as the management of public policies. this study aimed to observe if those conditions were crucial for the application of the method of planning in the catalan capital with a view to disseminating its model of planning worldwide, mostly in latin america. within this analysis, it was considered what supported the planning of the city of barcelona over time and the way it was set up. for this purpose, documentary and bibliographic research were made, as well as semi-structured in-depth interviews with different players that are involved with the plan. the data were analyzed through the technique of content analysis, concluding that the most influencing constraint for adoption and perpetuation of the method of planning in barcelona was the institutional constraint, because, throughout time, the region in question developed institutions that are able to carry out public policies for the long term. thus, applying barcelona's methodology of planning in other regions would require some adjustments.

Abstract: Significant improvements to the technique of minicutting Eucalyptus clones have been reported in the literature. However, despite these recent efforts, studies addressing the proper size of minicuttings and the reduction of leaf area have not been well explored. Thus, the present study had the objective of evaluating the effects of the length of the minicuttings and the leaf area reduction on the growth and nutritional condition of Eucalyptus urophylla during propagation. The experiment was conducted for 90 days in the Plantar Reforestation Co. Nursery in the municipality of Curvelo, MG, using a randomized block design with 4 replicates in a factorial arrangement. The effects of 4 lengths of minicuttings (4, 6, 8, and 10?cm), 2 levels of leaf area reductions (0 and 50%), and 2 commercial clones were studied. The length of the minicuttings and the reduction of leaf area did not affect the nutritional status of the leaves, nor did the length affect the quality of the plants at the age of 90 days. The results indicate that it is unnecessary to reduce the leaf area for Eucalyptus propagation. 1. Introduction The propagation of plants by minicuttings is a widely used technique employed for the production of Eucalyptus seedlings and has been published in various media. The scientific literature has shown that much of the success of this technique depends on the selection of the appropriate propagules and proper silvicultural practices, which aim to ensure efficiency in the production of high-quality seedlings [1]. In the production process, nurseries customarily produce clonal Eucalyptus plants with minicuttings ranging in size from 4 to 10 cm, with at least two pairs of leaves of reduced leaf area [2, 3]. The basic procedure for the reduction of leaf area on minicuttings used in most nurseries today is virtually the same as was used in plant propagation by cuttings (macrocuttings) in the 1980s and 1990s, although the vegetative propagules of minicuttings are smaller and more juvenile compared with macrocuttings. In addition, irrigation systems in nurseries have evolved significantly in recent years [4]. The retention of leaves or parts of leaves on the stem is necessary for the production of auxins and rooting cofactors that are translocated to the cutting base and promote rooting [5, 6]. Lima et al. [7] evaluated the effect of a reduction in leaf cuttings of Mikania spp. (Guaco) and found that an increase in leaf area positively influenced the percentage of rooting and the survival of the plants. Reuveni and Raviv [8] observed a higher percentage of rooting

Battery Recharging Issue for a Two-Power-Level Flywheel System
Janaína Gon alves de Oliveira,Hans Bernhoff
Journal of Electrical and Computer Engineering , 2010, DOI: 10.1155/2010/470525
Abstract: A novel battery recharging system for an all-electric driveline comprising a flywheel with a permanent magnet double wound synchronous machine (motor/generator) is presented. The double winding enables two voltage levels and two different power levels. This topology supersedes other all-electric drivelines. The battery operates in a low-power regime supplying the average power whereas the flywheel delivers and absorbs power peaks, which are up to a higher order of magnitude. The topology presents new challenges for the power conversion system, which is the focus of this investigation. The main challenge is the control of the power flow to the battery when the vehicle is parked despite the decay of the flywheel machine voltage; which is dependent on its charge state, that is, rotational speed. The design and simulation of an unidirectional DC/DC buck/boost converter for a variable rotational speed flywheel is presented. Conventional power electronic converters are used in a new application, which can maintain a constant current or voltage on the battery side. Successful PI current control has been implemented and simulated, together with the complete closed loop system.
Inulin and Oligofructosis: a review about functional properties, prebiotic effects and importance for food industry

Semina : Ciências Exatas e Tecnológicas , 2002,
Abstract: Nowadays consumers are more conscious about the relation between food and health. Therefore food industry has been looking for food that has a lot of benefits besides good flavor and appearance. Inulin and oligofructose are fructose polimers, vastly found in plants as storage carbohydrates. They present important functional for the food industry. Both inulin and oligofructose have been used as fiber bulk in food products. Differently from other fibers, they do not add flavor, allowing the food to be improved without changing its viscosity. Inulin and oligofructose have similar nutritional properties. Inulin is more indicated for obtaining products with a low fat content such as ice cream, cake and soup, while oligofructose is indicated for yogurt with a low caloric value and in order to mask the residual flavor from high intensity sweeteners used in food preparation. Research has shown that inulin and oligofructose have prebiotic effects because they are not digestible and they can develop bifidogenic effects, improving the intestinal microflora. The simultaneous use of inulin and oligofructose with probiotic agents in food is recommended for symbiotic effects.
