1. An Anchorage System for Enhanced Bond Behavior between Carbon Fiber Reinforced Polymer Sheets and Cracked Concrete
Abstract The contribution of CFRP wraps, as an anchorage system, to enhancing bond behavior between CFRP sheet and cracked concrete, was investigated. Thirty six concrete blocks (150 x 150 x 200 mm) were cast with 3ϕ12 mm steel bars embedded laterally at different spacing along the 200-mm-dimension. Half of the moist-cured blocks were subjected to a cyclic

2. Utilization of banana stalk fiber as reinforcement in low density polyethylene composite
ABSTRACT Natural fibers could serve as viable and abundant alternatives to the expensive and non - renewable synthetic fibers as reinforcement in thermoplastic composites. The potentiality of banana stalk fiber at reinforcing a low density polyethylene matrix was examined in this study. Fibers were extracted from the stalk of banana plant and characterized f

3. Evaluation of the Diameter Influence on the Tensile Strength of Pineapple Leaf Fibers (PALF) by Weibull Method
The fiber extracted from pineapple leaf (PALF) displays relevant mechanical properties that are motivating investigations for possible engineering application as polymer composite reinforcement. As any natural lignocellulosic fiber, the PALF presents non-uniform dimensions and heterogeneous properties with a significant dispersion of values. In fact, a marke

4. Characterization of xylanase from Streptomyces sp. FA1 and its application for bamboo hydrolysis
Native cellulose can be disintegrated into substructures with nano-size dimension through electronspinning. Typically, the most common source material available for cellulose nano-fiber production is wood. More attempts are employed to find new suitable resources to produce nano-cellulose at present. Bamboo boasts the abundant resource in China and possesses

5. Análise mercadológica para a implementação da tecnologia FTTH: uma aplicação do método SWOT / Marketing analysis for FTTH technology implementation: an application of SWOT method
The fiber optics is a transmission system that has been used to enable products that need high bandwidth, such as the telephone system, videoconferencing, local area networks (LANs), downloads of large files etc. In Brazil, we found an increased number of fiber optic networks. This ratify its advantages in relation to metal wire cable (immunity to electromag

6. Remodeling of the human dermis after application of salicytate silanol / Remodelamento da derme humana apos aplicação de salicilato de silanol
Mesotherapy is a technique that lacks scientifical clinical trials. In 2005, a controlled double-blind study in patients with photo-aged facial skin demonstrated the beneficial role of oral intake of silanol for skin, hair and nails. Facing it, a study was developed to compare histological alterations in human skin that received intradermal injections of sil

8. Complexity, Spirituality and Education: for an educability of the human spirit / Complexidade, Espiritualidade e Educação: por uma educabilidade do espírito humano
The theme of this research, Complexity, Spirituality and Education: for an educability of the human spirit, suggests that a problematic of understanding of the spirit and human spirituality is rooted not only religious reducts, but also in the actual fiber of science and also in the heart of modern society. We are sure and secure of this not only for its act

9. THURSTON GEOMETRIES AND SEIFERT FIBER SPACES / GEOMETRIAS DE THURSTON E FIBRADOS DE SEIFERT
We begin by studying orbifolds, i.e., topological spaces locally homeomorphic to quotients of Rn by finite groups. Then we study Seifert fiber spaces of dimension three which are certain type of foliations by circles that can be seen as fiber bundles over orbifolds. This material is useful in the subsequent study of Thurston model geometries. A Thurston mode

10. Analysis of cut-off conditions for coaxial fibers
This paper reports the analysis of modal normalized frequency cut-off of coaxial fibers having four dielectric layers. The cut-off curves are obtained for four different structures and several modes as a function of the several parameters of the fibers (refractive index and layer dimension). The calculation is done using a transcendental equation obtained in

11. Fundamentos matematicos das teorias de calibre
The purpose of this dissertation is to revisit, from the point of view of some modern mathematical methods, the mathematical foundation of gauge theories. We study in detail the theories of fiber bundles and of conections on fiber bundles. We formulate the gauge theories in the language of principal fiber bundles, finding the Klein-Gordon equation and the Kl

12. Changes in the Accumulation of [alpha]- and [beta]-Tubulin Isotypes during Cotton Fiber Development.
The expression of [alpha]- and [beta]-tubulin proteins in developing fibers and several other tissues of cotton (Gossypium hirsutum, cv Texas Marker 1) have been analyzed by immunoblots of one- and two-dimensional gels utilizing anti-tubulin antibodies as probes. As a percentage of total protein, fibers had greater amounts of tubulin than did hypocotyls, roo
