The expressive possibilities within the field of surface design come up with increasingly larger with the emergence of technologies that allow the construction of forms and structures of high complexity such as three-dimensional printing. Establishing a relationship between design and complex systems, this work seeks to address the significant interrelationship of new paradigms of science, designed from concepts such as chaos, complexity and self-organization along with the cyber and parametric design, assuming thus the consequent impact of these in the creation and construction of process surfaces. Starting from the investigation of the applicability of the aforementioned conceptual bases, will be exemplified prospects of surface, produced in the first instance through computer interfaces, assigning the emergence of new creative processes and technology. Furthermore, elucidating biomimetics and its importance in the design of the design as a means of inspiration in complex systems of nature.

INTRODUÇÃO: O reparo tissular é o objetivo final da cirurgia. A cultura celular requer arcabouço mecânico que dê suporte ao crescimento celular e difusão dos nutrientes. O uso do plasma rico em plaquetas (PRP) como um arcabouço 3D possui diversas vantagens: é material biológico, de fácil absorção pós-transplante, rico em fatores de crescimento, em especial PDGF- ββ e TGF-β que estimula síntese de matriz extracelular na cartilagem. OBJETIVO: Desenvolver arcabouço 3D à base de PRP. MATERIAIS E MÉTODOS: Duas formas foram idealizadas: Sphere e Carpet. Condições estéreis foram utilizadas. O gel de plaquetas permaneceu em cultura celular, observado diariamente em microscópio invertido. RESULTADOS: Ambos arcabouços obtiveram sucesso, com aspectos positivos e negativos. DISCUSSÃO: A forma Sphere não aderiu ao plástico. Observou-se retração do gel e investigação ao microscópio dificultada devido às áreas opacas no campo visual. A forma Carpet não aderiu ao plástico e apresentou-se translúcida. O tempo de estudo foi de 20 dias. CONCLUSÕES: A produção de um arcabouço 3D PRP foi um sucesso, e trata-se de uma alternativa que necessita ser mais utilizado e investigado para que se consolide em uma rota eficiente e confiável na tecnologia de engenharia tissular, particularmente em cultura de tecido cartilaginoso.

Most of the hydraulic turbines that are running in the world are the Francis type, because they are able to fit a wide range of head and flow. We also can declare that most of the installed hydraulic energy up to this date is generated by this type of turbine. On the other hand, if we pay attention to mechanical details of a Francis turbine we will see that among the three most used types it is the one that presents the more complex design. And, the simplest one is the Pelton type, whereas the Kaplan is the one less utilized. This work aims to develop the hydrodynamic calculation of a Francis turbine as well as to obtain its assembly drawing and 3D modeling drawing. In this way all details must be shown therefore needing a complete knowledge about this issue. Both 2D and 3D drawings help much if one wants the machine to be running in its power house. It is well noted that most of the entities that design and manufacture the Francis turbines are not brazilian. In this way the more we study how to design this kind of machine the more is our contribution to our country in order to conquer technology and manufacture Francis turbines

Art can be understood as a process in which knowledge is used to perform certain skills. From Latin ARS, technical means and / or ability, in Greece, there was the word art, but "Tekne", which originated from the word "technical." So art and technique are present in sculptures, paintings, shoes or ships. In this sense, designers, engineers and all professionals who use technology can be called artists. Considerations must be made regarding the level of energy embedded in the material from its production until its use, even considering recycling, sustainability and life cycle of materials. This study aimed to present the use of scanning technology and 3D virtual modeling and its application in prototyping with CNC (Computed Numerical Control) as a tool in current use cutting-edge courses in arts, design and engineering and their relations with sustainability.

This research presents an investigation about the relevance of visualization in teaching geometry. Our interest turns to analyzing the use of technology in teaching geometry, seeking to highlight their contribution to learning. The students of today - second decade of the 21st century - require that, each time more, the school move towards the integration of technologies for teaching since tablets, smartphone, netbook, notebook are items present on daily life of most students. Thereby, we investigate, taking the phenomenological orientation, the potential of educational software, especially the Geogebra 3D, directed at teaching math and favoring the work with the geometry viewing. At work we bring some theoretical considerations about the importance of viewing for the geometric learning and the use of technologies. We build an intervention proposal for the classroom of the 7th year of elementary school with tasks aimed at visual exploration and allow the teacher to work the concept of volume of geometric solids
