1. Analysis of Compositional Modification of Commercial Aluminum Bronzes to Obtain Functional Shape Memory Properties
In copper-based shape memory alloys (SMAs), some exceptional phenomena, such as the shape memory effect (SME) or superelasticity (SE), are observable. However, commercial aluminum bronzes, Cu3Al-based alloys, do not present these functional properties (SME and/or SE) in their original state. Thus, since one of the main copper-based SMA systems is the Cu-Al-N

2. Ultrasonic method of microvibration detection: part II - additional processing method and applications
Abstract Introduction In the last 28 years, the scientific community has been using elastography to evaluate the mechanical properties of biological tissue. The aim of this work was the optimization of the UDmV method, presented in Part I of the series, by means of modifying the technique employed to generate the reference sine and cosine functions, used fo

3. Novos materiais para aplicações analíticas nas determinações de compostos orgânicos de interesse farmacêutico e ambiental / New materials for analytical application in organic compound determination for pharmaceutical and environmental interests
Carbon film sensors, built from resistors of 2 Ω nominal resistance, were employed for application in the environment and pharmaceutical fields without previous modification of the electrode surface. When these sensors are electrochemically treated they obtain a wider potential window (both anodic and cathodic regions) than many other forms of carbon. D

4. Preparação e caracterização de materiais ferroelétricos de composição Bi4Ti3O12 contendo Lantânio e Érbio / Synthesis and characterization of Bi4Ti3O12 ferroelectric materials containing Lanthanum and Erbium
This work describes a systematic study of the influence of the lanthanum atom addition in the Bi4Ti3O12 (BIT) phase and the erbium atom addition in the Bi3,25La0,75Ti3O12 (BLT075) phase in terms of their synthesis process and its structural, microstructural and electrical properties. Ceramics of nominal composition Bi4-xLaxTi3O12 (BLTx) with 0 x 2 mol% and B

5. Multivariable predictive controller with excitation constraint for closed-loop identification. / Controlador preditivo multivariável com restrição de excitação para identificação de processos em malha fechada.
In MPC implementation, the process models development and definition is the most critical and time consuming task. Normally, the models are obtained through plant identification tests where perturbations are individually introduced in the manipulated variable while the controlled variable open-loop behavior is observed. For this reason, the application of cl

6. Da estrutura de expressões nominais quantificadas em posicão de tópico
Como se sabe, DPs topicalizados são sujeitos a uma restrição de definitude, assim, um elemento indefinido não pode aparecer na posição de tópico Cf. Hankamer, 1971; Kuno, 1972; Pontes, 1987; Raposo, 1996; Kato, 1998, entre outros). Assim, sintagmas determinantes quantificados (SDQs) não podem ser topicalizados nem em Inglês nem no Português do Bras

7. Dynamic load tests on small diameter auger piles with modified tip / Provas de carga dinâmica em estacas escavadas de pequeno diâmetro com ponta modificada
Auger pile foundations have been widely employed for light to medium loads. As the executive process cant avoid the degradation of the bottom excavation in situ soil properties, the only reliable resistance is a lateral friction parcel. However, these tip piles, many times, reaches relatively resistant strata and cant take advantage from these strata qua

8. Posttranslational side chain modification of a viral epitope results in diminished recognition by specific T cells.
A stretch of 16 amino acid residues within the nominal phosphoprotein of rabies virus was shown to carry an immunodominant epitope for class I- and class II-restricted T cells. The nominal phosphoprotein of rabies virus is thought to be heterogeneously phosphorylated at multiple serine and threonine residues. The synthetic peptide that expressed the T-cell e

9. Adenovirus type 2 coded single-stranded DNA binding protein: in vivo phosphorylation and modification.
The adenovirus type 2-coded single-stranded DNA binding protein (DBP) was shown to be a phosphoprotein and to exist in at least two forms that differ in mobility by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. After a 30-min pulse with [35S]methionine or 32PO4, 35S- or 32P-labeled DBP had a nominal molecular weight of 74,000 whereas after a 30-

10. Three-dimensional structure of beta 2-microglobulin.
The three-dimensional structure of beta 2-microglobulin, the light chain of the major histocompatibility complex class I antigens, has been determined by x-ray crystallography. An electron density map of the bovine protein was calculated at a nominal resolution of 2.9 A by using the methods of multiple isomorphous replacement and electron density modificatio

11. Nonstructural Protein Precursor NS4A/B from Hepatitis C Virus Alters Function and Ultrastructure of Host Secretory Apparatus
The nonstructural proteins of hepatitis C virus (HCV) have been shown previously to localize to the endoplasmic reticulum (ER) when expressed singly or in the context of other HCV proteins. To determine whether the expression of HCV nonstructural proteins alters ER function, we tested the effect of expression of NS2/3/4A, NS4A, NS4B, NS4A/B, NS4B/5A, NS5A, a
