1. A New Triple Band Microstrip Fractal Antenna for C-band and S-band Applications
Abstract Recently research show that some parameters such as the shapes of antenna patch and the ground plane when geometrically altered produces changes in the current density distribution of the planar structure and consequently in the resonant modes. This paper presents a new microstrip fractal antenna using the technique of inserting slots of shape fract

2. New synonymies and a revalidation in the spider genera Eustala and Micrathena (Araneae: Araneidae)
In this study, 10 nominal species of Eustala Simon, 1895 are synonymized with other species of the genus, mostly based on matching males and females erroneously described as different species. Parawixia rimosa (Keyserling, 1892) is considered a senior synonym of Eustala decemtuberculata Caporiacco, 1955. Eustala isosceles Mello-Leitão, 1939 is transferred t

3. HQ feature: descritores de forma utilizando a curva de Hilbert
A classificação e recuperação por similaridade baseadas em descritores de formas são processos de grande importância em tarefas de reconhecimento de padrões e recuperação de formas baseada em conteúdo. O desenvolvimento de descritores eficientes para caracterizar a forma ainda é um desafio. Este trabalho se concentra no desenvolvimento de novos ex

4. Identificação de uma linguagem por meio da gramática da forma : as casas do arquiteto Renato Righetto / Identification of a language through shape grammar : the houses of architec Renato Righetto
The study of shapes as a tool of analysis in design, based on matching possibilities of elements and operations, can disclose generation strategies of particular shapes from a determined architect. These strategies can, once proved its existence, characterize a style that can be used in the generation of new compositions in architecture. The method known as

5. Study on preparation of a vovel silica adsorbent and its selective separation applied to genistein
In order to selectively separate genistein from its crude solution, a novel silica adsorbent was prepared using genistein as the template molecule, gamma-aminopropylthriethoxysilane as the functional monomer and tetraethyl orthosilicate as the cross-linker. It was analyzed by the BET, FTIR, TEM characteristics, the static adsorption experiment, and selective

7. SEISMIC PATTERN RECOGNITION USING TIME-FREQUENCY ANALYSES / RECONHECIMENTO DE PADRÕES SÍSMICOS UTILIZANDO ANÁLISES TEMPO-FREQÜÊNCIA
Independent of the adopted methodology to perform the seismic facies analysis, the geological oriented spatial and temporal segmentation of the reservoir region should be carefully done. Depending on the complexity of the reservoir system, seismic data quality, and the experience of the interpreter, the level of confidence in an interpretation can vary from

8. Sequential shape-and-solder-directed self-assembly of functional microsystems
We demonstrate the fabrication of packaged microsystems that contain active semiconductor devices and passive components by using a directed self-assembly technique. The directed self-assembly is accomplished by combining geometrical shape recognition with site-specific binding involving liquid solder. Microfabricated components with matching complementary s

9. Structural polymorphism in the major groove of a 5S RNA gene complements the zinc finger domains of transcription factor IIIA.
Metal complexes that bind to DNA on the basis of shape-selection have been used to map the conformational features of the DNA binding site for transcription factor IIIA. Conformationally distinct segments are detected on the 5S rRNA gene that correspond closely to the binding sites identified for the individual zinc finger domains of the protein. The local c

10. Shape determinations of ribosomal proteins in situ.
Ribosomes are heterogeneous for neutrons because RNA and proteins have different neutron-scattering-length densities. This heterogeneity is an obstacle to the shape determination of single ribosomal components within the ribosome. Therefore, we homogenized (matched) the neutron-scattering-length densities of RNA and proteins. 23S and 5S RNA from the large ri

11. Hippocampal morphometry in schizophrenia by high dimensional brain mapping
Theories of the pathophysiology of schizophrenia have implicated the hippocampus, but controversy remains regarding hippocampal abnormalities in patients with schizophrenia. In vivo studies of hippocampal anatomy using high resolution magnetic resonance scanning and manual methods for volumetric measurement have yielded inconclusive results, perhaps because

12. Crystal structure of the CD2-binding domain of CD58 (lymphocyte function-associated antigen 3) at 1.8-Å resolution
The binding of the cell surface molecule CD58 (formerly lymphocyte function-associated antigen 3) to its ligand, CD2, significantly increases the sensitivity of antigen recognition by T cells. This was the first heterophilic cell adhesion interaction to be discovered and is now an important paradigm for analyzing the structural basis of cell–cell recogniti
