Disposição construtiva aplicada em contenção ortodôntica. Patente de modelo de utilidade para uma disposição construtiva aplicada em contenção ortodôntica, compreendida por ser do tipo 3x3, com encaixe do tipo "macho-fêmea", sendo que na base da "fêmea" (1) são procedidas retenções (2) mecânicas para fixação por meio de colagem na face lingual dos caninos (3) inferiores, com resina composta, de modo que no interior da "fêmea" (1) é provido um orifício (4) para o encaixe do "macho" (5) e, no centro da cavidade é provido um anel (6) elástico que se encaixa precisamente numa canaleta feita no pino (7) de encaixe do "macho" (5), sendo que, na extremidade dos "machos" (5) podem existir prolongamentos (8) metálicos para retenção de acrílico (9) ou então meios de encaixe para soldagem de um fio metálico (10) espesso, que contorna a face lingual dos dentes (11); inferiores anteriores, de modo que, quando se optar pela retenção em acrilico (9), um fio metálico (10) mais delgado é soldado no terminal de encaixe do "macho" (5) e logo após, o fio (10) e o terminal são recobertos por acrilico (9), sendo que os "machos" (5) poderão ter angulações nos braços (12) de encaixes.

This article approaches possibilities and strategies of building to development of fashion product. It investigates the application of different constructive resources of textile materials of same composition and trim, establishing for this parameters of formal similarity. The conception of products process is conducted by three-dimensional expression, which allows the steps for creating and delivering happen simultaneously. Three-dimensional modeling techniques enable the buildings that are structured by the following features investigated: intervention in the textile surface, insertion of independent elements, and different confection resolutions. The results instigate reflection about the processes involved.

Origami folds and kirigami cuts merged in an oriental technique called Origamic Architecture (or 3D kirigami) that has intrinsic relationships with geometry as well as these paper arts. Despite its potential, it is not very used as a didactic resource because of the lack of parameters in its construction. There are many studies about programs development and computational language to help the design of pop-up structures, as origamic architecture is also known. However, there are few studies concerning the study of positioning the lines and creases, which is essential in the process of creating a 3D kirigami design, especially in the development of spatial perception of the figure. Limited to the 90o open type models, this article is about the establishment of some initial guidelines for design of an origamic architecture through visual elements as point, line and shape. It is presented some basic models to illustrate the constructive parameters detected as well as some models elaborated by the author, showing the viability of the guidelines established.

During a long time, origami was associated with decoration and craft production of ornaments and figures. However, in the end of 20th century, it began to be studied by mathematicians who were looking for interrelationships between this art and science. Through disciplines like geometry, trigonometry, calculation and linear algebra, they generated a set of axioms and theorems that became possible specific conversion of origami in computational geometry and the development of several softwares. Thus, origami began to be applied in engineering and design studies of innovative product and the term “origamics” was created to demonstrate its interdisciplinary nature. In this article will be presented some works exploring the constructive principles of origami to contribute with the diffusion of origamics. In this way more professionals will be able to understand the scientific and technological potential of this art.

We aim to analyse the text written by Eça de Queirós, “Carta ao Sr. Mollinet”, theorizing the stylistics of Marcel Cressot’s expression, called “the texture”. We discuss what is sought in the reading of a text nowadays: the form, the meaning or the form that produces meaning? Even though through stylistics there is identifi cation and description of the linguistic categories in the text, the morphological identifi cation in the enunciation level is emptied, if it is done separately. It is from the semantic-syntactic and melodic axes that Eça infl ates his characters with life. The characterization of Pacheco and Portuguese people is supported by the nexus, a producer of antagonistic meta-signifi cation in relation to the fi rst meaning. Eça’s irony results from the reverse meaning – from “ne pas dire”. The nexus is the great meaningful cohesion between logical and metalogic discourse – producing new signifi cations; multiplying verbal resources, which are created in order to metamorphose the linguistic sign into pictorial or iconic signs. The irony governs the whole constructive tessitura that stems from new referents, which result from demiurgical relations between themselves because of the metalogical process, as it allows to establish and change the direction when sign and referent, signifi er and signifi ed, utterance and context are related. The analysis of Eça’s selected text enriches the discoveries presented by the Stylistics of Expression.

The lack of motivation and the excessive quantity of subject memorization are some of the main causes for the disinterest of students when learning chemistry. To change this scene, it's necessary that the teachers reinvent themselves and innovate during their classes, making use of alternative methodologies for the chemistry teaching process. The objectives of this work are to evaluate, from a constructive methodology approach, the characteristics, possibilities and limitations of some techniques and methods of teaching. This analysis allowed to present the results in the form of a table summarizing these characteristics and can be useful for teachers to choose the right strategy to be used

This paper presents a mathematical model adapted from literature for the crop rotation problem with demand constraints (CRP-D). The main aim of the present work is to study metaheuristics and their performance in a real context. The proposed algorithms for solution of the CRP-D are a genetic algorithm, a simulated annealing and hybrid approaches: a genetic algorithm with simulated annealing and a genetic algorithm with local search algorithm. A new constructive heuristic was also developed to provide initial solutions for the metaheuristics. Computational experiments were performed using a real planting area and semi-randomly generated instances created by varying the number, positions and dimensions of the lots. The computational results showed that these algorithms determined good feasible solutions in a short computing time as compared with the time spent to get optimal solutions, thus proving their efficacy for dealing with this practical application of the CRP-D.
