Identification of key microhabitats for fish assemblages in tropical Brazilian savanna streams
(Wiley-Blackwell, 2012-12-01)
The habitat use by stream fish can provide an understanding of this important component of species niches, and the changes in the availability of certain structures of instream habitats have a strong influence on the ...
Comparison of four trap types for ambrosia beetles (Coleoptera, Scolytidae) in Brazilian Eucalyptus stands
(Amer Entomol Soc, 2000-12-01)
Eucalyptus spp. plantations represent >60% of the reforested area in Brazil. Although ambrosia beetle attacks on live trees were at first nonexistent, they have begun to appear with greater frequency. Monitoring for pest ...
Coupling Surface-Enhanced Resonance Raman Scattering and Electronic Tongue as Characterization Tools to Investigate Biological Membrane Mimetic Systems
(Amer Chemical Soc, 2010-05-01)
The surface-enhanced Raman scattering (SERS) effect and sensor and biosensor analyses are widely applied to investigate drug-biomolecule interactions or to detect trace amount of analytes. In this work, surface-enhanced ...
Portable smart films for ultrasensitive detection and chemical analysis using SERS and SERRS
(Wiley-Blackwell, 2012-04-01)
Metallic nanostructures, much smaller than the wavelength of visible light, which support localized surface plasmon resonances, are central to the giant signal enhancement achieved in surface-enhanced Raman scattering ...
Incorporation of Ag nanoparticles into membrane mimetic systems composed by phospholipid layer-by-layer (LbL) films to achieve surface-enhanced Raman scattering as a tool in drug interaction studies
(John Wiley & Sons Ltd, 2010-01-01)
The synergistic effect produced by nanoparticles when incorporated into different systems used as analytical tools represents a growing research field nowadays. on the other hand, the study of interactions involving ...
Spatial distribution of trachoma cases in the City of Bauru, State of São Paulo, Brazil, detected in 2006: defining key areas for improvement of health resources
(Sociedade Brasileira de Medicina Tropical - SBMT, 2013-04-02)
Introduction: The objective of this study was to analyze the spatial behavior of the occurrence of trachoma cases detected in the City of Bauru, State of São Paulo, Brazil, in 2006 in order to use the information collected ...
A joint theoretical and kinetic investigation on the fragmentation of (N-halo)-2-amino cycloalkanecarboxylates
(2002-06-15)
A combined theoretical and experimental study to elucidate the molecular mechanism for the Grob fragmentation of different (N-halo)-2-amino cyclocarboxylates with the nitrogen atom in exocyclic position: (N-Cl)-2-amino ...
Effect of thermal treatment on the morphology of PLZT thin films prepared from polymeric precursor method
(2001-01-01)
Lead lanthanum zirconate titanate (PLZT) thin films with (9/65/35) stoichiometry were prepared by dip coating from polymeric precursor method. The films deposited on silicon (100) substrates, were thermally treated from ...
An exploration of the genetic robustness landscape of surface protein families in the human protozoan parasite trypanosoma cruzi
(Ieee-inst Electrical Electronics Engineers Inc, 2007-09-01)
The ability of genes to be robust to mutations at the codon level has been suggested as a key factor for understanding adaptation features. It has been proposed that genes relevant to host-parasite interactions will tend ...
Sensitive Affimer and Antibody Based Impedimetric Label-Free Assays for C-Reactive Protein
(Amer Chemical Soc, 2012-08-07)
C-reactive protein (CRP) is an acute phase protein whose levels are increased in many disorders. Levels greater than 3 mu g/mL serum have hitherto been considered to indicate pathology, but there is increasing interest in ...
