13. Evaluation of bulk and surfaces absorption edge energy of sol-gel-dip-coating SnO2 thin films
The absorption edge and the bandgap transition of sol-gel-dip-coating SnO2 thin films, deposited on quartz substrates, are evaluated from optical absorption data and temperature dependent photoconductivity spectra. Structural properties of these films help the interpretation of bandgap transition nature, since the obtained nanosized dimensions of crystallite

14. DEVELOPMENT OF A GYPSUM COMPOSITES AND DUST COCONUT FIBER. / DESENVOLVIMENTO DE COMPÓSITOS A BASE DE GESSO E PÓ DE FIBRAS DE COCO
The uses of renewable materials, as well as the reduction, reuse and recycling of the residues indicates the search for technological alternatives for sustainable development. In this context are the materials used in building. For the plaster is the building the largest market, because its use from the core products, and also from the first constructive ste

15. Investigação estrutural de filmes moleculares por microscopia de varredura por força / Structural Investigation of molecular films by scanning force microscopy
Molecular films constituted by ruthenium polypyridine complexes, triangular ruthenium acetate clusters, and polymetallated porphyrins have been systematically investigated, providing a wide range of functional interfaces for electronic devices, sensors, photoconversion and electrocatalytical cells. Such films have been generated by dip coating, drop casting

16. Target identification of buried coated objects
We consider the three dimensional electromagnetic inverse scattering problem of determining information about a buried coated object from a knowledge of the electric and magnetic fields measured on the surface of the earth corresponding to time harmonic electric dipoles as incident fields. We assume that the buried object is a perfect conductor that is (poss

17. Silicone resin to improve corrosion resistance of Zn and ZnFe coated steel
Chromatation pre-treatments have been widely used to improve galvanized steel corrosion resistance. However, due to the high toxicity of chromate ions, chromatation pre-treatments tend to be banned and, in last years, alternative coating systems are under investigation. Recently, polysiloxanes have been developed for application as coatings. Among them, and

18. Functional properties of the albume and quality of eggs of hen covered with protéico concentrate of bovine milk serum. / Propriedades funcionais do albume e qualidade de ovos de galinha cobertos com concentrado proteico de soro de leite bovino.
Egg white proteins are extensively used as processed food because of their functional properties, as gelation and foam formation. Depending on the storage conditions, some physical, microbiological, chemical and functional changes may occur. Functional food properties may be preserved when foods are coated by edible films, since both the loss of moisture and

19. Characterization of coating systems
Polymeric film coatings have been applied to solid substrates for decorative, protective, and functional purposes. Irrespective of the reasons for coating, certain properties of the polymer films may be determined as a method to evaluate coating formulations, substrate variables, and processing conditions. This article describes experimental techniques to as

20. Studies of activated GPIIb/IIIa receptors on the luminal surface of adherent platelets. Paradoxical loss of luminal receptors when platelets adhere to high density fibrinogen.
The accessibility of activated GPIIb/IIIa receptors on the luminal surface of platelets adherent to damaged blood vessels or atherosclerotic plaques is likely to play a crucial role in subsequent platelet recruitment. To define better the factors involved in this process, we developed a functional assay to assess the presence of activated, luminal GPIIb/IIIa

21. Expression of Functional Recombinant Mussel Adhesive Protein Mgfp-5 in Escherichia coli
Mussel adhesive proteins have been suggested as a basis for environmentally friendly adhesives for use in aqueous conditions and in medicine. However, attempts to produce functional and economical recombinant mussel adhesive proteins (mainly foot protein type 1) in several systems have failed. Here, the cDNA coding for Mytilus galloprovincialis foot protein

22. The permeability of rat palatal mucosa maintained in organ culture.
The intercellular permeability barrier of neonatal rat palatal mucosa maintained in organ culture for periods up to 24 days was studied ultrastructurally using the tracers horseradish peroxidase and lanthanum nitrate. At all time intervals examined the limit of penetration of the tracers corresponded to the level at which the membrane-coating granules were b

23. The Outer Membrane of Brucella ovis Shows Increased Permeability to Hydrophobic Probes and Is More Susceptible to Cationic Peptides than Are the Outer Membranes of Mutant Rough Brucella abortus Strains
The permeability of the outer membrane (OM) to hydrophobic probes and its susceptibility to bactericidal cationic peptides were investigated for natural rough Brucella ovis and for mutant rough Brucella abortus strains. The OM of B. ovis displayed an abrupt and faster kinetic profile than rough B. abortus during the uptake of the hydrophobic probe N-phenyl-n

24. Alteration of leukotriene release by macrophages ingesting Toxoplasma gondii.
Mouse resident peritoneal macrophages incubated with ionophore A23187 or opsonized zymosan released leukotrienes (LT) B4 and C4 (LTB4 and LTC4) and LTC4 and LTD4, respectively. In contrast, incubation with Toxoplasma gondii, an obligate intracellular protozoan, led to the formation of 11-, 12-, and 15-hydroxyicosatetraenoic acids (HETEs), together with an un
