13. A New Jacobi-based Iterative Method for the Classical Analysis of Structures
Abstract Traditionally, classical methods of structural analysis such as slope-deflection and moment distribution methods (Cross method) are used for primary analysis of structures and also controlling the results of computer programs. The main objective of this paper is to introduce a new method for classical computing and extending it to a matrix formulati

14. Stability of concrete beam-columns under follower forces
An axial follower force acting on the free end of a beam-column is known to remain tangential to its elastica at that point. Elastic beam-columns exhibit infinitely high buckling resistance to static compressive follower load. Loss of their dynamic stability is known to occur at critical follower loads, by flutter characterized by vanishing lateral displacem

15. Comunidade fitoplanctônica no monitoramento de rios do estado de São Paulo / Phytoplankton community in monitoring rivers of São Paulo state
There are few studies conducted on phytoplankton inhabiting the rivers. In São Paulo State many of the abstraction of water for public supply are located in lowland rivers and streams of low gradient and have a lot of dam built in their courses, and the presence of lateral lakes and small dams to capture water, contributing to the development of planktonic

17. Analysis by the finite element method of the stress distribution in prosthetic components placed in implants with morse cone connection in the anterior maxilla / Análise pelo método dos elementos finitos da distribuição de tensões em componentes protéticos posicionados em implantes com conexão cone morse na região anterior da maxila
The aim of this study was to evaluate through the three-dimensional method of the finite elements the stress distribution in the bone / implant interface and implant / abutment on implants with morse cone connection, placed in the anterior maxilla. From a virtual reconstruction of bone from a CT scan, cantilever prosthesis (11-21) was simulated using prosthe

18. Anti-swing Controller Based on Time-delayed Feedback for Helicopter Slung Load System near Hover
Abstract: In this paper, a new anti-swing controller for helicopter slung load system near hover flight is proposed. This controller is based on time-delayed feedback of the load swing angles. The output from this controller is additional displacement that was added to the helicopter trajectory in the longitudinal and lateral directions. Hence, its implement

19. The antimicrobial effect of 0.1 ppm ozonated water on 24-hour plaque microorganisms in situ
Ozone is a known oxidant present in the atmosphere and is commercially produced by simple ozonizer machines. It is a powerful antimicrobial agent in its gaseous and aqueous forms. Ozone readily dissolves in water and retains its antimicrobial property even in the dissolved state. In this study, the effect of 0.1 ppm ozonated water was analyzed on 24-hour sup

20. Provas de cargas estáticas instrumentadas em profundidade em estacas escavadas de grande diâmetro (Estações). / Static loading tests instrumented in large diameter drilled piles.
Objetivou-se estudar o comportamento de estacas escavadas de grande diâmetro em uma obra de um Shopping Center na cidade de São Paulo. As estacas foram submetidas a carregamentos axiais de compressão, sendo que as estacas foram instrumentadas em profundidade. Utilizou-se de teorias amplamente conhecidas no meio técnico com o propósito de interpretar as

22. Avaliação de sincronização lateral entre pedestre e passarela utilizando um excitador pneumático controlado por lógica fuzzy / EVALUATION OF LATERAL SYNCHRONIZATION BETWEEN PEDESTRIANS AND FOOTBRIDGE USING A PNEUMATIC EXCITER CONTROLLED BY FUZZY LOGIC
Em passarelas de grande vão, vêm sendo observado que o tráfego de pedestres pode induzir oscilações de baixas frequências. A proximidade entre as frequências naturais da estrutura e as frequências de excitação pode resultar na ocorrência do fenômeno de ressonância, ocasionando dificuldades de uso da estrutura por receio de seu colapso por parte

23. Curtain color and lighting program in broiler production: III - thermal comfort
The objective of this study was to evaluate the thermal comfort of broilers reared under two lighting programs (almost continuous and intermittent) in broiler houses with yellow or blue lateral curtains. The experiment was carried out from June 24, 2004 until May 12, 2005. Six consecutive flocks were housed in four 12 × 10 m broilers houses internally divid
