1. Structure and Properties of Dual-doped PEDOT:PSS Multilayer Films
Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is the most successful transparent conductive polymer widely used in functional organic devices. However, its potential in fabrication of highly conductive electrodes still has not been fully explored. This paper is an attempt to fill the existing gap of knowledge on possible post-treatments

2. Crotalus durissus terrificus crotapotin naturally displays preferred positions for amino acid substitutions
Abstract Background Classically, Crotalus durissus terrificus (Cdt) venom can be described, according to chromatographic criteria, as a simple venom, composed of four major toxins, namely: gyroxin, crotamine, crotoxin and convulxin. Crotoxin is a non-covalent heterodimeric neurotoxin constituted of two subunits: an active phospholipase A2 and a chaperone p

3. PF/CLAY hybrid materials: a simple method to modulate the optical properties
Abstract The aim of this work was modulate the emission properties and improve thermal stability of a conjugated polymer incorporated into an inorganic matrix. Hybrid material was prepared based on poly(9,9-dioctylfluorene-co-phenylene (PF) and montmorillonite (Na+Mt) clay using wet impregnation of 10, 30 and 50 wt.% of PF into Na+Mt and Na+Mt intercalated w

4. Managerial response to stockouts: the effect of remedies on consumer behavior
Abstract Stockouts remain a significant problem for retail firms. Estimates of stockout rates in the past fifty years consistently averaged approximately 8 percent. The consequences of stockouts transcend the retail store to include its supporting supply chain. In addition to the effect on the behavior of consumers, stockouts can impact the firm’s replenis

5. Um estudo sobre a Teoria da Predição aplicada à análise semântica de Linguagens Naturais. / A study on the Theory of Prediction applied to the semantical analysis of Natural Languages.
In this work, computer learning is studied as a problem of induction. Starting with the proposal of an architecture for a system of semantic analisys of Natural Languages, the two modules necessary for its construction were built and tested independently: a pre-processor, capable of mapping the contents of texts to a representation in which the semantics of

6. For an expanded concept of genre chain / Para uma concepção ampliada de cadeia de gêneros
This research presents a review of the concept of genre chains from their origins in Bakhtin (2000 [1953]) to the discussion of the criteria proposed by Fairclough (2001a [1992], 2003) and Swales (2004) for its characterization. For these authors, genre chains is a systematic grouping of genres that are a regular transformation necessary, predictable and, co

7. Localization of vibrational modes in low dimensional systems : an application to DNA / Localização de modos vibracionais em sistemas de baixa dimensionalidade : uma aplicação ao DNA
ln this work we studied the localization of vibrational modes of three simple models of DNA: unidimensional chain, double chain and the model of falir chains. ln these models, atomic groups were replaced by effective fiasses linked to each other by springs. For each model, the dynamic matrix was calculated and diagonalized obtaining the vibrational modes wit

8. Phonon multiplexing through 1D chains
Recently, phonon propagation through atomic structures has become a relevant study issue. The most important applications arise in the thermal field, since phonons can carry thermal and acoustic energy. It is expected that technological advances will make possible the engineering of thermal paths according to convenience. A simple phonon multiplexer was anal

9. Avaliação da potencialidade de argilas de queima clara como matérias-primas para o desenvolvimento de novos produtos cerâmicos
The industries of structural ceramics are among the most important production chains in the state of Rio Grande do Norte. The industry and other interest groups to target the replacement of firewood by natural gas. Studies accordingly concluded that simple change does not guarantee products of superior quality, and that the increase in spending on fuel can e

10. Recurrent neural nets for networks inference of gene interactions using Markov chains / Redes neurais recorrentes para inferência de redes de interação gênica utilizando cadeias de Markov
Array technologies have made it strainghtforward to simultaneously monitor the expression pattern of thousands of genes. Thus, a lot fot data is being generated and the challenge now is to discover how to extract useful information from these data sets. Microarray data is highly specialized. It involves several variables in a nonlinear and temporal way, dema

11. Nanoparticle self-assembly using patterns formed by dewetting / Auto-organização de nanoparticulas utilizando padrões formados por transição de molhabilidade
In this work, we study an original method to promote self-assembly of gold and silica nanoparticles using patterns formed by dewetting of aqueous solutions of poly (N-isopropylacrylamide) (PNIPAM) and sodium dodecylsulfate (SDS). Dewetting is a process where the free surface of an initially stable thin liquid film becomes unstable and deforms to engender rup

12. Propriedades de equilÃbrio e de transporte da matÃria de vÃrtices em nanoestruturas supercondutoras
In the present thesis, we study theoretically the equilibrium properties and dynamics of the vortex matter in two classes of nanostructured superconductors: (i) mesoscopic samples, with dimensions comparable with the penetration depth; and (ii) films with periodic array of artificial traps. In both cases, the vortex lattice symmetry is strongly dependent on
