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.

The paper presents a historical explanation of the Notre Dame de Paris, studying the symbols and the elements of each of its major rose windows. Analyzes the stained glass in the form of rose windows from the point of view of their meanings, functions, symbols used in their divisions and plays its geometric construction.

This is a theoretical paper that seeks to work, through interrelations, concepts relating to contemporary aesthetics in parallel to phenomenon of perception. It begins with the aesthetic interaction between content and form in order to trace the development of perceptionexpression interaction, inserted into the mutual action of its physical and psychical aspects "through behind" a thinking mind. In order to generalize such interaction to reality itself as a natural and evolutionary cycle, we start from the analysis of perception of more complex organic beings, endowed with consciousness, to extend the question to the simplest organic beings, as even to inorganics. It is based upon principles of equilibrium and unity in diversity to highlight a historical fact that it seems undeniable: that man evolves and this evolution, their perception clears, while that is particularized your experience and aesthetic judgment. Having in the art, the activity can boost an evolution more profound while pleasurable.

A study on means of developing of perception and reading of the form by the conception and development of a Teaching Methodology of Drawing with emphasis in its early stages, its development and application in the initial stages of the Design process, dissecting it as a mental and physical process. We will be addressing the contributions of Geometry as a mean of simplification of the reading and materializing configurations as some pointers for addressing the Drawing teaching in the reported course.

Nutrient absorption and response of lettuce to phosphorus fertilization. The objective of this study was to evaluate the response of lettuce (cultivar Verônica) to different levels of phosphorus fertilization. The experiment was conducted from 25/09/2003 (sowing) to 03/12/2003 (harvesting) at the Fazenda Experimental São Manuel, UNESP/FCA, Botucatu/SP, under protective structures. The experiment was conducted in a randomized block design, with five treatments (0, 200, 400, 600 and 800kg.ha-1 of P2 O5, in the form of triple superphosphate) and five replications. Plants were grown in 13L plastic pots containing Latossolo Vermelho Distrófico Típico. A quadratic response was observed for the fresh mass of the plant shoots and leaf area, with maximum equivalent levels of 733 and 756kg.ha-1 of P2 O5 , respectively, as well as for potassium, calcium, magnesium, sulfur, boron, copper, iron, manganese and zinc accumulation. Linear increases were observed with the treatments of P2 O5 for dry mass of the shoots, leaf number, plant height and nitrogen and phosphorus accumulation.
