1. PHYSICAL AND MECHANICAL PROPERTIES OF THE BAMBUSA VULGARIS AS CONSTRUCTION MATERIAL
ABSTRACT The fabrication of traditional construction materials consumes a large amount of energy, emits pollutants, and utilizes nonrenewable raw materials. Therefore, it is important to reduce the environmental impact of construction through the use of eco-friendly materials, such as bamboo. This work presents the characterization of Bambusa vulgaris, which

2. Using the Interval Metric for Modeling Entities Geometrics in ℝ2 - Case Study Interval Circumference
ABSTRACT The study of some distances provide science a way to separate two entities. It has applications in various fields such as remote sensing, data mining, pattern recognition and multivariate data analysis and others. If the distance is a Hausdorff metric, the guarantee is that all individuals are available. With the use of the distance of Trindade et a

3. O estabelecimento do paradigma do membro articulado no De motu animalium de Aristóteles
Resumo: No De motu animalium, Aristóteles recorre ao método analógico na pesquisa que faz acerca da causa comum do movimento, estabelecendo o paradigma do membro articulado, modelo que ele operacionaliza tendo em vista tornar inteligível o caráter dinâmico do movimento dos animais. Contudo, o membro articulado não se apresenta como modelo de uma manei

4. Numerical study of the behaviour of loop bar splicing in joints of reinforced concrete structures
Resumo Emendas com barras retas ocupam muito espaço devido ao comprimento de traspasse necessário. Dessa forma, em situações em que há uma limitação de espaço para a emenda, uma armação que constitui uma solução interessante é a emenda por meio de laço, que, apesar de ter poucos estudos relacionados, vem sendo bastante difundida na construção

5. Geometric optimization associated with the use of high-strength concrete in viaducts
Resumo O Brasil carece de investimentos em infraestrutura rodoviária, uma vez que este é responsável por mais da metade do volume de cargas transportado no território nacional. Quando se aborda o tema de infraestrutura rodoviária, uma das principais variáveis é, sem dúvida, a construção e a manutenção de viadutos. Viadutos em concreto de longarin

6. DISEÑO Y CARACTERIZACIÓN TEÓRICA DE MATERIALES FOTOACTIVOS EFICIENTES BASADOS EN DERIVADOS DE NAFTOPIRROL Y DE NAFTOTIOFENO PARA CELDAS SOLARES ORGÁNICAS
In this research we have designed electron donors D-π-A type containing two different π fragments to obtain naphthopyrrole (D-NPR-A) and naphthotiophene (D-NTP-A) derivatives, proposed for the use in organic bulk hetero-junction (BHJ) solar cells (OSCs). These derivatives were characterized by DFT and TD-DFT calculations. For all the electron donors the an

7. Génesis Semiótica de los Enteros
Abstract The traditional presentation of the integers ring generates difficulties for learning the product with its well-known signs rule. Our working hypothesis is that the solely representation of the product of two natural numbers by the area of a rectangle can hinder the vision of the product of two integers. Referring us to the scheme of Mathematical Wo

8. Paquimé. Influencia del Pensamiento Matemático y Astronómico Mesoamericano
This paper refers to the study of the social practice of the construction of Mesoamerican ceremonial centers, in order to relate it to the actual construction of Cross Moundat, in the Paquimé region, northwest of the state of Chihuahua, Mexico. The mound was an astronomical observatory consisting of a 15 meter long and 13.70 wide base originally oriented to

9. As construções geométricas e a gênese instrumental: o caso da mediatriz
This thesis deals with the Instrumental Genesis, which is the preparation process of instrument by the subject. Studies on national and international levels have addressed this process, however, no studies that dealt with Instrumental Genesis referring to an abstract artifact were found. This research revealed the bisector as an abstract artifact. Thus, the

10. Modelagem do comportamento dinâmico de edifícios mistos (aço-concreto) submetidos à ação do vento. / Modeling of the dynamic behaviour of steel-concrete composite buildings submited to wind actions.
Based on a favorable economic scenario and technological advances of material sciences and construction processes, in the last three decades, the Brazilian cities have presented a substantial growth, with respect to construction of residential and commercial multi-storey buildings. Nowadays, these buildings present greater slenderness and have been construct

11. Instrumentos virtuais de desenho e a argumentação em geometria
This dissertation presents a proposal to work, at school, the deductive reasoning in geometry. The proposal makes use of digital material consisting of virtual drawing tools that perform geometric transformations of translation, reflection, rotation and enlargement. Making use of digital material, it was developed a didactic sequence consists of three stages
