1. Synflorescence morphology of species of Typha L. (Typhaceae): anatomical and ontogenetic bases for taxonomic applications
ABSTRACT The inflorescence of plants of the genus Typha L. consists of a polytelic system with the fertile region containing staminate flowers in the terminal portion and pistillate flowers in the basal portion. Although some useful morphological information has been provided to characterize species of the genus, various divergent typologies have arisen due

2. 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

3. Concepção de uma seqüência de ensino para o estudo da semelhança: do empírico ao dedutivo
The aim of this research is to investigate how the concept of similar figures can be presented in a significant and motivate way to the students attending the first grade of Brazilian high school system, so that the proof can be an integrant part of this process. We tried to answer the research questions: How is the transition from concrete geometry to space

4. O conceito de semelhança: uma proposta de ensino
The aim of this research was to analyse the difficulties dealt with by first form students attending the Brazilian high school system, as well as to check to what extent a teaching sequence using the concept of homothetic integrated with Geometric Optics can favour the learning of the concept of similarity. Our preliminary studies lead us to observe that tea

7. Unification Theorem for the Two Basic Dualities of Homothetic Demand Theory
When income elasticities of demand are all unity, every dollar being spent in the same proportions at all levels of income, a homogeneous-first-degree, concave utility function exists to serve as an unequivocal measure of real output. Dual to it, and with identical concavity and homogeneity properties, is the minimized-cost-per-unit-of-output, a function of
