1. Spectrum Continuity and Contiguity based Dedicated Protection for Flexible Optical Networks
Abstract Elastic optical networks (EONs) have been pointed out as a promising candidate for transporting data with high transmission rates in adaptive optical networks. Consequently, the occurrence of a failure in a simple element may cause the interruption of various services. Survival mechanisms have been crucial to try to overcome the problems created by

2. Neurotological Findings at a Health Unit for Adults with Cervicalgia
Abstract Introduction The cervical spine is a flexible link between the sensory platform of the skull and torso. The fundamental principle of its operation is due to the balance between muscle strength and flexibility, and any dysfunction of this balance causes neck pain, known as cervicalgia. Objective The objective of this study is to analyze the most pr

3. O planejamento econômico no Brasil: considerações críticas
In the past thirty years, a series of plans have been developed by successive Brazilian governments in a continuing effort to maximize the nation's resources for economic and social growth. This planning history has been quantitatively rich but qualitatively poor. The disjunction has stimulated Professor Mello e Souza to address himself to the problem of nat

4. Simultaneous control and piezoelectric insert optimization for manipulators with flexible link
This work proposes a tracking control model for a flexible link robotic manipulator using simultaneously motor torques and piezoelectric actuators. The dynamic model of manipulator is obtained in a closed form through the Lagrangian approach. The control uses the motor torques for the tracking control of the joints and also to reduce the low frequency vibrat

5. O processo de tomada de decisão: a cognição e a experiência decisória de executivos de uma empresa do setor elétrico brasileiro.
The goal of this dissertation is to understand the decision making from the link between the experience of decision and cognitive scheme of executives of a company s energy sector. The specific objectives are: determine the common principles as perceived by executives surveyed in the decision-making process, based on Simons model of rationality limited; iden

6. THREE ESSAYS ON REGIONAL ECONOMICS
The study on regional economics has two particular characteristics that differentiate it from any other field in economics. Macroeconomic variables and national borders are not the focus of analyses, even though regional planners can measure the regional effects of national policies. In this aspect, areas of study in which microeconomic instruments are the m

7. DEVELOPMENT OF A THREE DEGREE-OF-FREEDOM PNEUMATIC LINK FOR FLEXIBLE ROBOTIC MANIPULATORS / DESENVOLVIMENTO DE UM ELO PNEUMÁTICO DE 3 GRAUS DE LIBERDADE PARA MANIPULADORES ROBÓTICOS FLEXÍVEIS
Recently, the concept of flexible manipulators has attract great interest. These devices present a continuously deforming vertebral column, in opposition to the traditional robotic manipulators link/joint/link with rigid links. Flexible systems offer a potential increase in the capacity of interaction with the environment, being apt to adjust itself to the c

8. ConsultÃrio privado para populaÃÃo de baixa renda: o caso das âclÃnicas popularesâ na cidade do Recife
Historically the private health services net has been busy with actions of average and high complexity, exactly those that, for requiring massive technological incorporation, they guarantee high profitability for the business men of the sector. What seems to be new is the interest in commercialize actions which complexity degree of the procedures that accomp

9. Dinâmica e controle de movimento de corpo rígido de um manipulador robótico rígido/flexivel / Dynamic and control of rigid body motion of a rigid/flexible robotic manipulador
This work presents a study of the dynamics and control of the movement of rigid body of a robotic manipulator. The model of the manipulator, consisting of a mechanism with two flexible links hardwired by meetings that do not suffer deformations, was gotten through the Formularization of Lagrange and the Admitted Modes Method. For matching effect, two other m

10. Sobre a modelagem e dinamica de estruturas flexiveis de rastreamento (pequenas e grandes deflexões)
In this work two models are developed to slewing flexible structures with just one link: a model considering small deflections and a model considering great deflections. For both models, the Extended Hamilton s PrincipIe is utilized so one can obtain the goveming euqations o fmotion. This equations are then nondimensionalized so one can obtain a smalI nondim

11. Triple helix formation at distant sites: hybrid oligonucleotides containing a polymeric linker.
An oligonucleotide hybrid is described which possesses two triple helix forming oligonucleotides which have been connected by a flexible polymeric linker chain. As a prototype, binding of this class of oligonucleotide to duplex DNA has been studied using a segment of the HSV-1 D-glycoprotein promoter, which possesses a pair of 12bp target sites for stable tr

12. Solution structure of a DNA hairpin and its disulfide cross-linked analog.
The solution structures of a 21 base long DNA hairpin derived from the ColE1 cruciform, and an analog possessing a disulfide cross-link bridging the terminal bases, have been determined by NMR spectroscopy. The 8 bp long stem of these sequences adopts a B-form helix whereas the five base long single-stranded loop appears to be flexible and cannot be represen
