1. Nitretação a plasma da junta soldada do aço inoxidável super duplex SAF 2507
RESUMO Os aços inoxidáveis superduplex (AISD) apresentam em sua microestrutura as fases ferrita e austenita, de modo a conciliar boas propriedades mecânicas e de resistência à corrosão. Estes materiais possuem grande aplicação na indústria de extração de petróleo e na petroquímica. Quando estão sujeitos a estas aplicações, os dutos de AISD so

2. Estudo teórico e experimental de esforços devidos a cabos de termometria fixados em estruturas de coberturas de silos cilíndricos para armazenamento de grãos / Theoretical and experimental study of efforts due to temperature cables fixed to roof structures of cylindrical storage silos for granular products
Um dos acidentes comuns em estruturas de armazenamento é o colapso da estrutura de cobertura do silo. Na prática, observa-se que as ruínas estruturais nesse sistema são na maior parte devidas ao desconhecimento das ações nestas estruturas. Devido à escassa informação disponível sobre os esforços de cabos de termometria fixados em estruturas de cob

3. Prediction of the temperature distribution of partially submersed umbilical cables
The objective of this work is to predict the temperature distribution of partially submersed umbilical cables under different operating and environmental conditions. The commercial code Fluent® was used to simulate the heat transfer and the air fluid flow of part of a vertical umbilical cable near the air-water interface. A free-convective three-dimensional

4. Contribuição sobre a utilização de microprocessadores para medida e controle de temperatura e umidade
This work presente the development of an intelligent indenpendent microsystem to measure and control the temperature and humidity of a system of food storage of large dimensions. The system communicates with the exterior through a standard interface, IEC-625 and can be integrated into a larger system, through circular or star-shaped connections and may be co

5. EXPERIMENTAL INVESTIGATION ON THE STRESS RELAXATION BEHAVIOR OF A HIGH-STRENGTH ARAMID FIBER / ESTUDIO EXPERIMENTAL DEL RELAJAMIENTO DE UNA FIBRA SINTÉTICA DE ALTA RESISTENCIA / ESTUDO EXPERIMENTAL DA RELAXAÇÃO DE UMA FIBRA SINTÉTICA DE ALTA RESISTÊNCIA
High-strength aramid fibers have been used in the production of a variety of cables and ropes which have found several applications as structural members in bridges and other types of structures. For such applications, a sound knowledge of the time dependent material properties is highly important. An experimental investigation on the stress relaxation behav

6. Caracterização de geis tixotropicos utilizados em telecomunicações
This work is enclosed in a project of development of national technology in Telecommunications with participation of UNICAMP and TELEBRÁS Research and Development Center. Today, a number of the materials used in optical cables are imported, without a specific knowledge of their behavior in the Brazilian climate conditions. The gels used for cable filling ar

7. Contribuição ao estudo das coberturas penseis
This work presents a finite element approach to static and dynamic analysis of counterstressed cable structures. Two nodes, constant strain finite elements are used to model hanging cables, plane prestressed cable trusses and 3-D prestressed cable networks. The two nodes elements are assembled with tniss, beam and frame elements to the static analysis or mix

8. Metodo de calculo de isolamento de torres de transmissão de energis eletrica face ao risco desejado para surto de manobra
The cost of an electrical transmission line depends greatly on the cost of its towers, which in turn are priced according to their dimensions and weight. These factors are greatly influenced by the insulation and particulary by the dimensions of the air-gaps. Large air-gaps have lower risks-of-failure when submitted to a given electrical stress than srnaller

9. Flutuações de composição em um elastomero dieletrico processado por extrusão
Dielectric polymer materials, such as the elastomers based on poly(ethylene/propylene/1,4-hexadiene), also called EPDM or ethylene-propylene rubbers, are normally used for the electric insulation of hiqh voltage cables. The dielectric strength of these materiaIs is one of the most significant properties for the evaluation of their performance, as a function

10. Recristalização das ligas supercondutoras do sistema Nb-Ti
Multifilamentary cables of Nb-Ti alloys have been used mainly in superconducting engines and devices. These alloys have high ductility and their final most important superconducting properties can be established by suitable metallurgical procedures. In this work the influence of the microstructural characteristics on the superconducting properties and of the

11. A Type V Myosin (Myo2p) and a Rab-like G-Protein (Ypt11p) Are Required for Retention of Newly Inherited Mitochondria in Yeast Cells during Cell DivisionV⃞
Two actin-dependent force generators contribute to mitochondrial inheritance: Arp2/3 complex and the myosin V Myo2p (together with its Rab-like binding partner Ypt11p). We found that deletion of YPT11, reduction of the length of the Myo2p lever arm (myo2-Δ6IQ), or deletion of MYO4 (the other yeast myosin V), had no effect on mitochondrial morphology, coloca

12. Sequence of events in the transformation process in cells infected with a temperature-sensitive transformation mutant of Moloney murine sarcoma virus.
Normal rat kidney cells infected with the temperature-sensitive transformation mutant of Moloney murine sarcoma virus were used to study the biochemical and morphological changes that occur during transformation. The infected cells exhibited a normal morphology at the nonpermissive temperature (39 degrees C) and a transformed morphology at the permissive tem
