Literature has a role to contribute in the affective, cultural and cognitive development os chindren and it also accumulates the function to form readers among others. Among several genres, there are the fairy tales that are eternal in the western culture and they are the first genres to be read spontaneously at home or to be taught at school. As all the symbolic language, the fairy tales are steeped in ideologies. Thus, the aim of this research is to investigate if the existing ideologies in two fairy tales – Cinderella and The Sleeping Beauty, both from Perrault, influence children between 9 and 10 years old as subjects. An empiric research of quantitative and qualitative approach was done and its data analysis followed the method of Content Analysis, and it has as register analysis unit the word, and of context the sentence (children’s answer). The choice os the classify the categories it was used the syntactic criteria because it’s the most appropriate to refer to register units from ideologies identified by scholars in the area. The results show that children with 9 and 10 years old are influenced by implied ideologies existing in the two fairy tales used in the process of data collection

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

This work aims to determine the stresses acting on the main beam of a crane to transport steel coils of up to twelve tons. To determine the stress it was made a revision of the knowledge of the mechanics of materials to apply the analytical method. Following a review of the finite element method is made to understand the same. To complete the study it was used the commercial software ANSYS to determine the stresses by finite element method, the program provides images that help to better understand the results obtained. With the results a comparison of the values of the tensions between the two methods (analytical and finite element) was made. To assist in the calculations it was used the NBR 8400, 1984 (Calculation of Lifting Equipment Load)

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.

Extraoral appliances represent an alternative for correction of Class II malocclusions. The application of external force leads to tooth movement and influence the growth of the maxillomandibular complex. This article aims to present the removable headgear as an adjuvant in the treatment of Class II division 1 in the mixed dentition.
