The present study aimed to analyze the floristic and structural descriptors of tree species natural regeneration in a forest sector with synchronized bamboo (Merostachys multiramea Hackel) die-off (CT) and an adjacent area with continuous canopy cover (ST) in an araucaria forest fragment in the municipality of Lages, Santa Catarina state. A total of 14, 5x5m, plots (six plots in CT sector and eight in ST sector) were allocated, where all tree species regenerative individual with circumference at breast height smaller than 15cm and height higher than 25cm was measured (diameter at soil level) and identified. The richest families were: Myrtaceae (nine), Solanaceae (six) and Aquifoliaceae (four). The Shannon Diversity Index in ST and CT sectors were respectively 2.73 and 2.31. The species with the highest importance values in CT sector were Solanum variabile, Piptocarpha angustifolia, Mimosa scabrella, Jacaranda puberula and Solanum pseudoquina. In ST sector, the species with highest importance values were Myrsine lorentziana, Casearia decandra, Cinnamodendron dinisii, Drimys brasiliensis and Ilex paraguariensis. The results showed that the synchronized bamboo die-off influenced the spatial variation in the floristic and structural descriptors of the tree species natural regeneration.

The author has verified the average depth of the mandibular fossa, in the X-ray image, using the oblique lateral transcranial technique from the right and left sides samples of each patient, which included a total of 176 patients, 87 male and 89 female. The patients were in following phases: deciduous dentítion (the patients had only deciduous teeth in the oral cavity or, if they had any permanent teeth, they could not be in occlusion), mixed dentition (the patients presented deciduous and permanent in the oral cavity) and permanent dentition (the patients had only permanent teeth in the oral cavity), until the eruption of the permanent third molars, in the region from São José dos Campos. São Paulo. Brazil. The patients were under treatment at the Dental School. UNESP (São Paulo State University). ln order to measure the depth of the mandibular fossa in millimeters an imaginary line was traced on the X-ray image, perpendicular to the other line that served as a reference, which was traced from the botton part of the articular eminence up to the tympanosquamous fissure. After the data were obtained and put in a data sheet, they underwent statistical analysis. The results showed that, in the average, the depth of the mandibular fossa in masculine sex is non-statistically signíficant larger than what was observed in feminíne sex, and the right side is larger than the left side, with significant statistical differences. However, only in permanent dentition, in masculine sex, the depth of the mandibular fossa on the right side is larger than on the left side with significant statistical differences

The aim of this study was to produce mix beverages of grape juice and soybean hydrosoluble extract (SHE) in laboratory scale. The raw materials were soybean (variety BRS 213), grape (species Vitis labrusca, variety Niagara Rosada), citric pectin, water and sugar. The mix beverage was produced with different proportions of SHE and grape juice (1:1; 1:1.5 and 1:2; respectively; m/m) and different soluble solids concentrations (10, 12 and 14 °Brix) obtained by adding granulated sugar (sucrose). Soybean hydrosoluble extract, grape juice and mix beverages were chemically analyzed (humidity, ash, protein, lipids, carbohydrate, reducing sugars, total reducing sugars, sucrose, titratable acidity and pH). The mix beverages were sensorial analyzed through the acceptance test (hedonic scale). The results of chemically analyzed were expressed as mean and standard deviation and the results of sensorial analyzed were submitted to variance analysis and the means were compared using the Tukey test at 5% of probability. The pH of mix beverages was lower than 3.9, without addition of acidulants. Sugar addition to mix beverages (10; 12 and 14ºBrix) increased the levels of soluble solids, total reducing sugar and carbohydrates, but it did not interfere in the reducing sugar concentration. The increased proportion of grape juice in mix beverages allowed observing the elevation of titratable acidity and reducing sugars levels, as well as the pH reduction. The increase of grape juice in mix beverage did not interfere in the acceptance of mix beverages. The more sweetened beverages were preferred by the sensory panel.

Em condições de hipóxia (redução da pressão parcial de oxigênio), respostas reflexas de aumento da ventilação pulmonar, aumento da pressão arterial e diminuição da frequência cardíaca são observadas com o objetivo de aumentar os processos de trocas gasosas e perfusão tecidual. Para que essas respostas reflexas à hipóxia ocorram, quimiorreceptores periféricos são ativados pela redução da pressão parcial de oxigênio arterial e enviam sinais excitatórios para o sistema nervoso central, promovendo a excitação de importantes núcleos cerebrais envolvidos com o controle das atividades respiratória, simpática e parassimpática. Evidências experimentais sugerem que os neurônios do complexo parabraquial/Kölliker-Fuse (PBN/KF), importante região respiratória localizada na porção dorsolateral da ponte, contribuem para o processamento das respostas cardiorrespiratórias do quimiorreflexo. Contudo, os neurotransmissores envolvidos ainda não foram explorados. No presente projeto, exploraremos a hipótese de que a neurotransmissão glutamatérgica da região PBN/KF é importante para a manutenção da ventilação basal e para o processamento das respostas ventilatórias à hipóxia. Para tanto, utilizamos a técnica de microinjeção de agonistas e antagonistas dos receptores de L-glutamato no PBN/KF de animais anestesiados e não anestesiados, avaliando parâmetros ventilatórios (eletromiografia dos músculos diafragma e abdominal em animais anestesiados; e frequência respiratória, volume corrente e ventilação minuto em animais não anestesiados) e parâmetros cardiovasculares (pressão arterial e frequência cardíaca em ambas condições experimentais) em condições de repouso ou em situações de estimulação dos quimiorreceptores periféricos (com cianeto de potássio). Nossos dados mostram que nos animais anestesiados houve uma redução...

This work deals with a problem of mixed integer optimization model applied to production planning of a real world factory that aims for hydraulic hose production. To optimize production planning, a mathematic model of MILP Mixed Integer Linear Programming, so that, along with the Analytic Hierarchy process method, would be possible to create a hierarchical structure of the most import criteria for production planning, thus finding through a solving software the optimum hose attribution to its respective machine. The hybrid modeling of Analytic Hierarchy Process along with Linear Programming is the focus of this work. The results show that using this method we could unite factory reality and quantitative analysis and had success on improving performance of production planning efficiency regarding product delivery and optimization of the production flow
