1. Cascade Modeling of the Measuring System Used to Assess S-Parameters of Anchor Rods on Power Transmission Lines Guyed Towers
Abstract The structural condition of the cable-stayed towers anchorage on power transmission lines requires constant monitoring. Maintenance routines must be able to identify faulty anchor rods and substitute them to avoid tower collapses and power delivery interruptions. Modern statistical diagnostic systems based on machine learning requires the generation

2. Different Strategies to Anchor Organotin Methoxides on Silica and Their (Re)Use as Heterogeneous Catalysts for Transesterification Reactions
Catalysts were prepared by the heterogenization of the tributyltin(IV) methoxide (n-Bu3Sn(OMe)) and dibutyltin(IV) dimethoxide (n-Bu2Sn(OMe)2) on silica by two strategies: (i) anchoring of the organotin(IV) compounds on silica and (ii) anchoring of the organotin(IV) compounds on a silica gel functionalized with mercaptopropyl groups (SiO2–SH). The characte

3. Aço carbono 1040 como indicador de agressividade do solo e da pasta de cimento em sistemas de ancoragem de linhas de transmissão
RESUMO O encapsulamento de hastes de âncora em pasta de cimento reduz o contato dos materiais metálicos com os ambientes agressivos, em torres estaiadas de linhas de transmissão de energia elétrica. Contudo, ainda são reportados casos de falha prematura devido à corrosão do sistema de ancoragem. O íon cloreto é considerado um dos principais respons�

4. Estudo do jateamento em solos argilosos e sua aplicação à engenharia de fundações offshore / Study of water jets in clay and its application to offshore foundation engineering design
Most of all petroleum produced in Brazil is encountered in marine deposits where the water depth may exceed 1000 meters. Recent discoveries of new offshore oil fields have motivated studies in this area designed to develop new techniques applied to oil exploration. For the extraction of oil deposits floating platforms are commonly used, supported by anchorag

5. Construção de sistema que permite a ancoragem de proteína recombinante à superfície celular de levedura. / Construction of a system that allows anchoring of recombinant protein to the cell surface of yeast.
Cell surface display systems have being developed for expression of heterologous proteins anchored to the cell surface of microorganisms. Several applications of these systems have been reported, including employment as whole-cell biocatalysts, development of vaccines and cellular biosorvents. In this work it was developed a system that allows the anchoring

6. Studies of the kinetic characteristics of alkaline phosphatase reconstituted in vesicular systems / Estudos das características cinéticas da fosfatase alcalina reconstituída em sistemas vesiculares
Alkaline phosphatase is a multifunctional enzyme, capable of hydrolyzing phosphate monoesters, pyrophosphate, phosphodiesters, as well as catalyzing transphosphorylation reactions, and it is named "alkaline" due to its ability to perform these reactions more efficiently in pH above the neutral (pH 8-11). The aim of this work was to standardize a methodology

7. Nexo de causalidade: o art. 13 do CP e a teoria da imputação objetiva
This work examines the relation of causality through the theory of objective imputation, searching to verify under different approaches, which is the ideal criterion to attribute a normative result to a criminally relevant behavior. It was taken care of to discourse on the function of the Criminal law (under the optics of the doctrine and the Brazilian legis

8. RESISTÊNCIA À TRAÇÃO DE UM SISTEMA DE ANCORAGEM EMBUTIDO EM CONCRETO SUJEITO A CARGA DE IMPACTO / TENSILE STRENGTH OF A CONCRETE ANCHORING SUBJECTED TO IMPACT LOAD
This work investigates the strength of a concrete anchor system constituted of headed studs embedded in concrete subjected to impact tension load. The main variable was the loading rate which varied from a minimum of 0,015 kN/s (static) to a maximum of 54885 kN/s. The anchor system was designed so that the failure was governed by concrete cone breakout. Elev

9. Estudo sobre o revestimento de fachadas de edifícios altos com placas de granitos ornamentais / Study on exterior dimension stone cladding systems with ornamental granites
O Brasil, no mercado mundial, ocupa lugar de destaque na extração e comercialização das rochas ornamentais e de revestimento, demonstrado pela produção mensal de chapas que é da ordem de 4 milhões de metros quadrados. Dentre suas as diversas formas de aplicações na construção civil, observa-se um incremento do uso em revestimentos de fachadas de

11. Estudo do fluxo gerado por agitadores tipo ancora
Stirred vessels and mixing systems are the core of the chemical industries, and probably they are the oldest equipment in chemical processing for desired products. Due its great importance to the industry, these processes have been developed through the time, and in the last decades, computational techniques have been used in the project and optimization of

12. Characterizing the flow of stirred vessels with anchor type impellers
Despite its importance in chemical industries, there are few works which studies anchor type impellers and only a fraction of the works investigate these systems under a computational approach. The great majority refers to turbine impellers, specially Rushton turbines, under turbulent flow. Anchor impellers are used specially for highly viscous flow, typical
