1. Clinical and pathological aspects of idiopathic pulmonary fibrosis in cats
RESUMO: As enfermidades pulmonares intersticiais são um grupo de doenças difusas do parênquima pulmonar, nas quais a fibrose pulmonar está incluída. O objetivo deste trabalho é caracterizar os achados clínicos e patológicos da fibrose pulmonar idiopática em três gatas, e avaliar possíveis agentes etiológicos através dos exames bacteriológicos,

2. Synthesis of Star-Shaped Lead Sulfide (PbS) Nanomaterials and theirs Gas-Sensing Properties
Star-shaped PbS nanomaterials are synthesized by a hydrothermal method. Morphology and structure of the PbS nanomaterials are analyzed by SEM, HRTEM and XRD. Gas-sensing properties of the as-prepared PbS sensor are also systematically investigated. The results show star-shaped PbS nanostructure consists of four symmetric arms in the same plane and demonstrat

3. HipersuperfÃcies cujas geodÃsicas tangentes nÃo cobrem o espaÃo ambiente / Hypersurfaces whose tangent geodesics do not cover the ambient space
Seja I : ∑n → Mn+1 uma imersÃo de uma variedade conexa n-dimensional ∑ em uma variedade Riemanniana completa conexa (n + 1)-dimensional M sem pontos conjugados. Suponha que a uniÃo das geodÃsicas tangentes a I nÃo cobrem M. Sobre essa hipÃtese temos dois resultados: 1. Se a cobertura universal de ∑ Ã compacta, entÃo M Ã simple

4. Desigualdades isoperimÃtricas para integrais de curvatura em domÃnios k-convexos estrelados / Isoperimetric inequalities for integrals of curvature in k-convex starshaped domains
Baseados nos trabalhos De Gerhardt e Urbas [12], [36], provamos um resultado de convergÃncia global e determinamos precisamente o comportamento assintÃtico de soluÃÃes de um fluxo geomÃtrico que descreve a evoluÃÃo de hipersuperfÃcies estreladas e k-convexas por funÃÃes das curvaturas principais. Como aplicaÃÃo, e seguindo o argumento de Guan e L

5. GrÃficos compactos com curvatura mÃdia de segunda ordem constante sobre a esfera / Compact graphs over a sphere of constant second order mean curvature
The purpose of this dissertation is to desire a formula for the operator Lr(g) = div(Pr gradient g) of a new support function g, defined over a hypersurface Mn in a Riemannian space form Mc n +1, and to show that a compact smooth starshaped hypersurface Σn in the Euclidean sphere Sn+1,whose second symmetric function S2 is positive and constant must be a

6. Avaliação da produção de toxina tetânica por "Clostridium tetani" cultivado por processos fermentativos descontínuo e descontínuo alimentado / Evaluation of the tetanus toxin for "Clostridium tetani" cultivated by batch fermentative and fed-batch process
The tetanus toxin is a neurotoxin synthesized by the bacillus Clostridium tetani that, after detoxification with formaldehyde, still exhibits antigenic and immunologic properties, hence its denomination of tetanus toxoid. Such a neurotoxin is produced by cultivations of the microorganism in vegetative form on a relatively complex specific medium containing g

7. The Douglas-peucker algorithm: sufficiency conditions for non-self-intersections
The classic Douglas-Peucker line-simplification algorithm is recognized as the one that delivers the best perceptual representations of the original lines. It may, however, produce simplified polyline that is not topologically equivalent to the original one consisting of all vertex samples. On the basis of properties of the polyline hulls, Saalfeld devised a

8. Synthesis and Characterization of Silsesquioxane-Based Polymer Hybrids with Controlled Structure
We have developed a method to obtain polymer hybrids with control of inorganic content and molecular configuration. Hybrid poly(methyl methacrylate) (PMMA) was obtained via atom transfer radical polymerization (ATRP) initiated by octafunctional cubic silsesquioxanes using CuCl as catalyst. Two different ATRP initiators obtained by attaching specific chemical

9. Contribuição sobre a utilização de microprocessadores para medida e controle de temperatura e umidade
This work presente the development of an intelligent indenpendent microsystem to measure and control the temperature and humidity of a system of food storage of large dimensions. The system communicates with the exterior through a standard interface, IEC-625 and can be integrated into a larger system, through circular or star-shaped connections and may be co

10. Three-dimensional structure of Theiler virus.
Theiler murine encephalomyelitis virus strains are categorized into two groups, a neurovirulent group that rapidly kills the host, and a demyelinating group that causes a generally nonlethal infection of motor neurons followed by a persistent infection of the white matter with demyelinating lesions similar to those found in multiple sclerosis. The three-dime

11. New medium for isolating iron-oxidizing and heterotrophic acidophilic bacteria from acid mine drainage.
A new solid medium is described for growing iron and heterotrophic bacteria from acid mine drainage (AMD). Examination of AMD from five states revealed several kinds of colonies of iron-oxidizing bacteria: (i) smooth, (ii) smooth with secondary growth sectors or branching, (iii) star-shaped, (iv) radiating lobe, and (v) flat-rough. All AMD samples yielded wh

12. The cellular receptor to human rhinovirus 2 binds around the 5-fold axis and not in the canyon: a structural view
Human rhinovirus serotype 2 (HRV2) belongs to the minor group of HRVs that bind to members of the LDL-receptor family including the very low density lipoprotein (VLDL)-receptor (VLDL-R). We have determined the structures of the complex between HRV2 and soluble fragments of the VLDL-R to 15 Å resolution by cryo-electron microscopy. The receptor fragments,
