1. Observação de vortices magneticos em calotas tridimensionais submicrometricas / Magnetic vortex observation in sub-micrometric tri-dimensional caps
Neste trabalho fizemos um estudo sistemático de filmes compostos por multicamadas Co/Pd depositados sobre arranjos auto-organizados de esferas de látex submicrométricas (50 ? 1000 nm). O filme depositado sobre a esfera (não-magnética) forma uma calota magnética com espessura variável. As espessuras de Co e Pd foram escolhidas de modo a obter duas clas

2. Síntese de compostos com potenciais atividades biológicas ou magnéticas
This thesis is divided in two parts and presents the results of our studies on the synthesis and the study of biological or magnetic proprieties of a series of ligands and their transition metal complexes. Firstly we prepared a series of dithiacarboxilic acids and their metal complexes to investigate the biological activity of these compounds against fungi,

3. Implantação de 111In em Ligas de Heusler Pd2MnZ (Z=Sn,Sb,Ge,In) usando Reações Nucleares com Ions Pesados: Medida de Campo Hiperfino Magnético pela Espectroscopia de Correlação Angular Gama-Gama Perturbada / Implantation of 111In in Heusler Alloys Pd2MnZ (Z=Sn,Sb,Ge,In) using Nuclear Reaction with Heavy Ions: Measurements of Hiperfine Field Magnetic for Spectroscopy of Perturbed Angular Correlation Gamma-Gamma
O presente trabalho apresenta uma metodologia nova de introduzir o núcleo de prova 111In em amostras para medidas de Correlação Angular Gama-Gama Perturbada (CAP). Para esta finalidade utilizou-se reação nuclear do tipo 108Pd(6Li,3n)111In. Para testar o método de implantação iônica foram utilizadas amostras de compostos intermetalicas tipo liga de H

4. A hierarchical spectral clustering and nonlinear dimensionality reduction scheme for detection of prostate cancer from magnetic resonance spectroscopy (MRS)
Magnetic resonance spectroscopy (MRS) has been shown to have great clinical potential as a supplement to magnetic resonance imaging in the detection of prostate cancer (CaP). MRS provides functional information in the form of changes in the relative concentration of specific metabolites including choline, creatine, and citrate which can be used to identify p

5. Effect of anticoagulants on binding and neutralization of lipopolysaccharide by the peptide immunoglobulin conjugate CAP18(106-138)-immunoglobulin G in whole blood.
The 18-kDa cationic protein CAP18 is an antimicrobial protein isolated from rabbit granulocytes that binds lipopolysaccharide (LPS) and inhibits many of its biological activities. We covalently coupled a synthetic peptide representing amino acids 106 to 138 of CAP18 to human immunoglobulin G (IgG) by using the heterobifunctional linker N-succinimidyl-3-(2-py

6. Galactoxylomannans of Cryptococcus neoformans.
Galactoxylomannans (GalXMs) from single isolates of Cryptococcus neoformans serotypes A, B, and D were isolated from culture supernatants and then purified by affinity, ion-exchange, and gel-filtration chromatography. GalXMs are a group of closely related complex polysaccharides. GalXMs from serotypes A (9759 A) and C (3183 C) and an acapsular mutant of sero

7. Isotactic polypropylene biodegradation by a microbial community: physicochemical characterization of metabolites produced.
From a selective enrichment culture prepared with different soil samples on starch-containing polyethylene we isolated four microaerophilic microbial communities able to grow on this kind of plastic with no additional carbon source. One consortium, designated community 3S, was tested with pure isotactic polypropylene to determine whether the consortium was a

8. Broad Neutralization of Human Immunodeficiency Virus Type 1 Mediated by Plasma Antibodies against the gp41 Membrane Proximal External Region ▿ †
We identified three cross-neutralizing plasma samples with high-titer anti-membrane proximal external region (MPER) peptide binding antibodies from among 156 chronically human immunodeficiency virus type 1-infected individuals. In order to establish if these antibodies were directly responsible for the observed neutralization breadth, we used MPER-coated mag

9. Putative RNA Capping Activities Encoded by Brome Mosaic Virus: Methylation and Covalent Binding of Guanylate by Replicase Protein 1a
Brome mosaic virus (BMV) RNA replication is directed by two virus-encoded proteins, 1a and 2a. The amino-terminal half of 1a is a distant homolog of alphavirus nonstructural protein nsP1, which has been implicated in capping viral RNAs. In this study, we examined the enzymatic activities of BMV 1a expressed in yeast, where the protein is fully functional in

10. Dynamic characteristics of optokinetically controlled eye movements following inferior olive lesions in the brown rat.
1. The inferior olive was destroyed by the drug 3-acetylpyridine in brown rats. Spontaneous and optokinetic eye movements in response to constant-velocity rotation (5-80 deg/s) or sinusoidal oscillations (0.05 and 0.1 Hz with 15 deg/s peak velocity and 0.3, 0.5, 1.0 and 2 Hz with 5 deg/s peak velocity) of the visual surround were recorded 4-6 days, 40-50 day
