1. SPATIAL VARIABILITY OF THE WATER DEPTH APPLIED BY FIXED SPRINKLER IRRIGATION SYSTEMS
Abstract The uniformity of water application is an important factor in the evaluation of sprinkler irrigation systems. This uniformity depends on the type of sprinkler and its operating conditions, such as the arrangement and spacing between the sprinklers in the area; velocity and wind direction during the period of water application and the pressure variat

2. Improvement of Circularly Polarized Slot-Patch Antenna Parameters by Using Electromagnetic Band Gap Structures
Abstract This paper is devoted to the design of a novel Electromagnetic Band Gap (EBG) circularly polarized slot-patch antenna in multilayered configuration. The operating frequency band can be controlled via the disk radius and adjusting the slit lengths. An arrangement combining the circular slot-patch antenna design and feeding sources included are consid

3. INTERAÇÕES FÁRMACO-RECEPTOR: APLICAÇÕES DE TÉCNICAS COMPUTACIONAIS EM AULA PRÁTICA SOBRE A EVOLUÇÃO DOS INIBIDORES DA ENZIMA CONVERSORA DE ANGIOTENSINA
Teaching classes and events regarding the molecular aspects of drug-receptor interactions is not an easy task. The ligand stereochemistry and the spatial arrangement of the macromolecular targets highly increase the complexity of the process. In this context, the use of alternative and more playful approaches could allow students to gain a more thorough unde

4. COMPARAÇÃO E CONSTRUÇÃO DE REATORES DE "MILD" E "HARD ANODISATION" PARA FABRICAÇÃO DE ALUMINA ANÓDICA POROSA
The mild anodization (MA) reactor is exemplified for its operational simplicity and its excellent control over the experimental parameters that are involved in the anodization process. This method provides porous anodic alumina films with a regular cell-arrangement structure. This offers a better cost-benefit ratio than the other equipment configurations tha

5. Raciocínio sobre conhecimento visual : um estudo em estratigrafia sedimentar / Reasoning over visual knowledge: a study in sedimentary stratigraphy
Imagistic domains are those in which problem-solving process begins with the recognition of domain objects trough the visual information captured, supporting more abstract interpretations in subsequent steps. The problem-solving process, in imagistic domains, is performed trough intensive application of visual knowledge, which corresponds to the set of menta

6. O ritual e os símbolos: a realização dos grafismos rupestres na região do município de Camalaú (PB)
This work aims to infer the relationship between the realm of myth with the production of rock graphics, ie, whether the production of these graphics are rituals linked to a mythic structure whatever, being able to express a sacred dimension. Through authors such as Eliade (1991, 1983, 2007, 2008 a, 2008 b), Leroi-Gourhan (2007), Levi-Strauss (1996, 2007, 20

7. Creche Odetinha: um estudo de caso / Creche Odetinha: a case study
This is a qualitative research, which aims at describing and analysing through a Case Study the training process (2009) of a group of recently selected/appointed child care workers -Day Care Center Assistants (Agentes Auxiliares de Creche, AAC1). In order to do so, the recent changes in early childhood education policies within the municipality of Rio de Jan

8. Algoritmos rápidos de detecção de colisão : broad phase utilizando KD-trees / Algoritmos Rápidos de Detecção de Colisão Broad Phase utilizando KD-Trees.
In this work, three novel and fast broad phase collision detection algorithms, which utilize the spatial partitioning structure known as KD-Tree, were proposed and implemented: KDTreeSpace, DynamicKDTreeSpace and StatelessKDTreeSpace. These algorithms were integrated to the Open Dynamics Engine (ODE) library, which is in charge of calculating the motion of t

9. The links among the circuits of urban economy in Brazil : the role of the wholesale distributor / Os elos entre os circuitos da economia urbana brasileira no atual periodo : os atacadistas distribuidores e seu papel intermediador
The current space division of labour increases the importance of circulation in production process and imposes a rapid and more frequent replacement of supplies, according to shorter stated periods, both in industry and retail. In Brazil, the opening of the economy, imposing a bigger competitiveness to the companies, and the social and territorial expansion

11. "Tomografia computadorizada, atenuação de raios gama e análise micromorfológica na avaliação de alterações na estrutura e retenção de água pelo solo" / Computed tomography, gamma-ray attenuation, and micromorphologic analysis to evaluate changes on soil structure and water retention
Soil structure is related to the arrangement of soil particles, aggregates, and pores, which makes part of this porous media. The influence of structure on soil physical phenomena ranges from macro to microscope scale. Structure changes in microscope scale are important because affect the soil particle arrangement and, consequently, the pores distribution. S

12. Secondary structure of the lac repressor DNA-binding domain by two-dimensional 1H nuclear magnetic resonance in solution.
A recently proposed approach for spatial structure determination in noncrystalline proteins by nuclear magnetic resonance was applied to the lac repressor DNA-binding domain. On the basis of sequence-specific 1H NMR assignments, the location of alpha-helices in the amino acid sequence was determined from nuclear Overhauser enhancement data and from amide pro
