1. New registers of colleters in species of Myrtaceae from Brazilian Cerrado
Resumo Coléteres são estruturas secretoras que produzem uma substância pegajosa, constituída por uma mistura de mucilagens, proteínas, terpenos, substâncias pécticas e até alcaloides, que lubrifica e protege o meristema apical. Vários tipos de coléteres têm sido descritos e apresentam valor taxonômico em muitas famílias botânicas. Em Myrtaceae,

3. A Model Predictive Guidance Strategy for a Multirotor Aerial Vehicle
ABSTRACT: The present study faces the problem of safely controlling the position trajectory of a multirotor aerial vehicle subjected to a conic constraint on the total thrust vector and a linear convex constraint on the position vector. The problem is solved using a linear state-space model predictive control strategy, whose optimization is made handy by rep

4. ROBUST CONTROL OF WIENER SYSTEMS: APPLICATION TO A pH NEUTRALIZATION PROCESS
Abstract In this paper, the robustness of a typical control scheme for Wiener systems is studied. These systems consist of the cascade connection of a linear time invariant system and a static nonlinearity. To control this kind of systems, several approaches were discussed in the literature. Most of these control schemes involve transformation of the measure

5. Anatomical investigations of Piper amalago (jaborandi-manso) for the quality control
Abstract Piper amalago L., Piperaceae, popularly known as jaborandi-manso, is a shrub that spans a height of 2–7 m. It can be found in the regions of Southern America downward up to the south of Brazil. Traditionally it is used to treat digestive problems, heart problems, and burns. This study aims to conduct an anatomical investigation and analysis of the

6. Influence of the Ultimate Torsion on the Geometry of Dental Implants
Este estudo avaliou o perfil de implantes submetidos à torção. Foram analisados quatro tipos de implantes (Conexão®): Master Porous (MP – implantes cilíndricos com encaixe hexagonal externo e superfície duplamente porosa; 11,5 X 3,75 mm), Master Screw (MS - implantes cilíndricos com encaixe hexagonal externo e superfície usinada; 11,5 X 3,75 mm),

8. Estudos químicos e anatômicos em espécies de Myrtaceae e Asteraceae e primeiros registros de coléteres em Myrtaceae / Chemical and anatomical studies in Myrtaceae and Asteraceae species and first report of colleters in Myrtaceae
This paper presents data on the chemical composition and antibacterial activity of volatile oils fron three Myrtaceae genera (Callistemon, Kunzea and Melaleuca) grown in Brazil, and one species of the Asteraceae family (Sphagneticola trilobata), ruderal and used in folk medicine. The volatile oils of Myrtaceae species were investigated for its chemical compo

9. Características da precipitação pluviométrica do nordeste brasileiro e seus padrões de acoplamento com as TSM do Pacífico Equatorial e Atlântico Sul. / Rainfall characteristics in northeastern brazil and their patterns coupling with sst equatorial Pacific and South Atlantic.
The eastern coast of the Northeast Brazil (NEB) is a region where transient weather systems interact with local systems, modulating their frequency and intensity. Understanding the mechanisms of such interactions may be instrumental in explaining the observed precipitation patterns in this region. The objective of this work is quite within this scope and tak

10. Estudo teórico e experimental das pressões em tremonhas cônicas e piramidais de silos metálicos esbeltos / A theoretical and experimental study on pressures in conical and pyramidal hoppers of slender metallic silos
The hopper structure is still an area of great uncertainties regarding the product flow and the acting pressures. Its behavior during loading and downloading products is little known. With the eccentricity of the discharge hopper, the uncertainties only increase, resulting, at times, in insecure or anti economic projects. This study design was based on the A

Desenvolvimento de plataforma elíptica osseointegrável para implante dentário, guias de perfuração e técnica cirúrgica de implantação - estudo em fêmures de cães / Development of osseointegrated elliptic platform for dental implant, surgical guides and surgical technique of implantation study in femurs of dogs
The aim of this study was to develop a dental implant for use in dogs with similar format to the biradicular teeth of these animals and surgical technique for its implantation, with features that allow the osseointegration. The implant is composed of three parts, two conic threaded implants united to a conic elliptical platform by screws and implanted below
