Durabilidade da argamassa mista de revestimento interno contendo dregs-grits em substituição à areia

This paper concerns about the durability of new material in construction. It is noteworthy the fact that increases increasingly searching for alternative materials that do not depend only of natural resources and at the same time be an alternative for reuse of industrial waste. Since the construction materials have a long life and a high cost of civil works and maintenance, it is crucial to estimate the behavior of a new product. Thus , this work discuss the durability of mixed mortar lining , made with waste from the process Kraft pulp production , known as dregs and grits , in partial replacement of sand. Tests were conducted to simulate conditions as adverse environments of constant heat and fire, with the aim of analyzing the behavior of mortar mixed matched the behavior of standard mortar

Avaliação das alterações dentárias e esqueléticas induzidas pelo uso do aparelho de Herbst no tratamento da classe II na dentadura mista: Revisão sistemática

Objective: evaluate the immediate dental and skeletal changes induced by the Herbst appliance on early treatment of Angle´s Class II malocclusion. Material and Method: several electronic databases such as Scopus, Pub Med, Medline, Cochrane Library, Lilacs and Scielo were searched. The abstracts that fullfilled the selection criteria were selected and those that did not provide enough information about these criteria were selected but the final decision of including them or not on the research, was taken after the complete reading of the article. The selection criteria were: clinical studies with Class II individuals, both male and female, with initial age of 7 to 10 years, treated with the Herbst appliance that analysed the dental and/or skeletal changes evaluated on lateral cephalometric radiographs; researches where the treatment performed did not involve extractions or surgical interventions; studies that included patients without syndromes or health concerns and articles published in English or Portuguese. Results and Conclusions: five articles were selected. The articles showed that significant changes happened in the mandibular sagittal lenght, on facial convexity angle, on maxillo-mandibular relationship, on retroclination of the upper incisors and on distal movement of the upper molars, on proclination of the lower incisors and on extrusion of the lower molars. The appliance exerted a limited effect on the anterior relocation of the maxillary complex and on facial heights. However, more studies about the performance of the Herbst appliance on early treatment of Class II are needed.

Regeneração natural do componente arbóreo após a mortalidade de um maciço de taquara em um fragmento de floresta ombrófila mista em Lages - SC

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.

Mensuração da profundidade da porção lateral da fossa mandibular, em imagens radiográficas da ATM, obtidas pela técnica transcraniana, em pacientes com dentição decídua, mista e permanente

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

Caracterização química e sensorial de bebida mista de soja e uva

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.

Nota científica: teste de aceitação de bebida mista de soja e amora

O objetivo deste trabalho consistiu em elaborar e avaliar a aceitação de bebida mista de extrato hidrossolúvel de soja (EHS) e suco de amora (SA). As bebidas, produzidas com diferentes proporções de EHS e SA (1:1; 1:1,5; 1:2 m/m), e diferentes concentrações de sólidos solúveis (10, 12 e 14 °Brix), foram analisadas sensorialmente e seus resultados foram submetidos à análise de variância e regressão. As diferentes proporções de EHS e SA nas bebidas produzidas interferiram no aroma e na aparência das bebidas; porém, não existiu uma relação direta entre essas proporções e a aceitabilidade desses atributos. O teor de sólidos solúveis, entretanto, influenciou o sabor e a impressão global. A preferência dos provadores, tanto no sabor como na impressão global, recaiu nas bebidas mais doces, havendo uma relação direta entre o teor de açúcar e a aceitação. Todas as bebidas formuladas foram aprovadas pela equipe de provadores.
