Influence of carrier phase on flicker measurement for rectangular voltage fluctuations
(IEEE, 2011-11-01)
This paper presents an analysis of the influence of the phase relationship between the fundamental frequency and the rectangular voltage fluctuation on flicker measurements made by the International Electrotechnical ...
Morphological study and photo-addressing in poly(styrene-b-butadiene-b-styrene) block copolymers with azobenzene groups and polystyrene matrix: influence of chemical bonding
(2011-01-25)
The main goal of this work was the synthesis of new azo-functionalized block copolymers
(BCP) from epoxidized poly(styrene-b-butadiene-b-styrene) modified with azobenzene
groups by one-step facile reaction between the ...
Rehabilitation of masonry arches with compatible advanced composite material
(Elsevier, 2011-12-01)
Stone masonry arches are structures of great functional and architectural importance as they may be found in a large number of constructions that are mainly historic buildings. Although relatively solid structures, time ...
Consules populares
(Cambridge University Press, 2011)
In the Late Roman Republic politicians labelled as populares were traditionally tribunes of the plebs. In our sources we found references to the great populares leaders Tiberius and Caius Sempronius Gracchus, Lucius Appuleius ...
Nanostructuration of self-assembled poly(styrene-b-isoprene-b-styrene) block copolymer thin films in a highly oriented pyrolytic graphite substrate
(Elsevier, 2011-01-03)
Highly oriented pyrolitic graphite (HOPG) is a useful substrate to visualize epitaxial formation due to its crystallographic structure. The morphology of a poly(styrene-b-isoprene-b-styrene) block copolymer thin film on a ...
In vitro activities of retapamulin and 16 other antimicrobial agents against recently obtained Streptococcus pyogenes isolates
(ASM, 2011-04-28)
Retapamulin in vitro activity against 400 Streptococcus pyogenes clinical isolates obtained from skin, pharynx, ear fluid, and blood samples recovered from 2007 to 2009 was studied. The isolates belonged to 26 different ...
Epidemiological and molecular analysis of Streptococcus pyogenes isolates causing invasive disease in Spain (1998-2009): comparison with non-invasive isolates
(Springer, 2011-10-01)
The incidence, clinical manifestations, and circulating clones involved in Streptococcus pyogenes invasive disease was analyzed in two regions of Spain between 1998 and 2009. The annual average incidence of invasive disease ...
Influence of the modification with MWCNT on the interlaminar fracture properties of long carbon fiber composites
(Elsevier, 2011-11-12)
This paper reports the processing of a carbon fiber reinforced epoxy composite with carbon nanotube integration and examines the potential improvement on the interlaminar toughness. Carbon nanotube enhanced composites were ...
Optimization of 100 µm alginate-poly-L-lysine-alginate capsules for intravitreous administration
(Elsevier, 2011-09-24)
The field of cell microencapsulation is advancing rapidly. Particle size plays a critical role in terms of biocompatibility and limits decisively its applicability. Producing reduced size microcapsules involves broadening ...
A clean up step of fat content previous to trace metal characterization in mussel tissues by inductively coupled plasma mass spectrometry
(Elsevier, 2011-05-24)
Inductively coupled plasma mass spectrometry analysis of trace and major elements of mussel tissues can be quickly and accurately analyzed after cleaning up the interfering fat content before the sample is digested in a ...
