1. Efecto de los parámetros de soldadura en mallas de acero electrosoldadas
ABSTRACT Reinforced concrete is the most widely used material in construction industry. Generally concrete is reinforced with ribbed bars. In certain applications, it is desirable to use welded mesh and are used in most reinforced concrete structures (buildings, roads, tunnels and prefabricated components). Welded mesh are generally electrowelded (PW: Projec

2. Comportamiento Tribológico y Microestructural en Recubrimientos Aplicados por GTAW y HVOF (Proceso Térmico de Espreado) y Usado en Recuperación de Aceros Grado Herramienta AISI/SAE D2
Abstract The Fe-Cr-Mo alloys are use in covers to protect the components that are under wear and corrosion. The high velocity thermo spray covering by HVOF (high velocity oxi-fuel) in Fe-Cr-Mo alloys has reported as a good result in projection fields for the steel tool grade for cold work. The HOVF is an attractive method to apply covering and recuperate dia

3. The transcendence of time in the epistemology of observation from a phenomenological standpoint
In this article I deal with time as a notion of epistemological content associated though with the notion of a subjective consciousness co-constitutive of physical reality. In this phenomenologically grounded approach I attempt to establish a 'metaphysical' aspect of time, within a strictly epistemological context, in the sense of an underlying absolute subj

4. Estudo da propriedade resistência superficial em revestimentos de argamassa / Study of surface strength property of mortar rendering
The lack of cohesion in mortar renderings corresponds to the loss of mechanical strength among theirs layers due to the weakening of particles bond, a fact which is reflected, among other events, by a low surface resistance of these renderings. Thus, poor surface strength of mortar renderings accelerates their degradation process, leading to a significant re

5. Aplicação de moire de projeção com deslocamento de fase na geração de modelos digitais topograficos de orgão vegetais / Applications of projection moire technique with phase shifiting to agricultural engineering problems
Shape definition of bodies exhibiting symmetric, non symmetric or irregular geometry is of fundamental necessity for science and technology developments. Applications of objects shape survey is reflected on several science fields as biology, human prosthesis and orthesis, medical diagnosis, prediction of surgical results, orthopedics, veterinary medicine, in

6. Manufacturing constraints applied to the topology optimization method. / Restrições de manufatura aplicadas ao método de otimização topológica.
The design of a mechanical component is a very complex task, which includes constraints such as maximum weight and maximum stiffness, and also manufacturing constraints, associated with the manufacturing processes required at the shop floor. It is known that Topology Optimization (TO), despite of being a very effective and powerful method to obtain optimal s

7. Avaliação de sistemas de produção de revestimentos de fachada com aplicação mecânica e manual de argamassa / Production evaluation of rendering façade with mechanical and manual application of Mortar
A falta de uma gestão mais efetiva e de uma visão sistêmica e os baixos níveis de racionalização e industrialização da produção de revestimento de argamassa no Brasil têm sido responsáveis pela alta variabilidade na produção, por índices insatisfatórios de produtividade e perdas e por problemas de qualidade do produto. Uma das etapas desse pr

8. Avaliação de diferentes topografias residuais na distribuição de tensões no remanescente dental por meio da análise de elementos finitos / Different residual topographic analysis in the distribution of tensions in the residual teeth by means of the finite element analysis
The presence of dentin projection above the finish line in the preparation of endodonticaly treated tooth to receive post and core is well established in literature, it influences positively in the resistance of the root. However, due to dental destruction, its not always possible to achieve a homogenous projection design, contributing for deficiencies in th

9. Aplicação de métodos tomográficos na reconstrução bi-dimensional de propriedades de chamas / Application of the tomographyc methods on bidimensional reconstruction of the flame properties
Fundamentally, flame diagnosis by tomographic imaging deals with reconstructing an image from its projections. In the strict sense of the word, a projection at a given angle is the integral of the image in the direction specified by that angle. However, in a loose sense, projection means the information derived from the emitted energies, at some angle, when

10. Dynamic simulation of constrained mechanical systems using recursive projection algorithm
In this paper, the dynamic simulation of constrained mechanical systems that are interconnected of rigid bodies is studied using projection recursive algorithm. The method uses the concepts of linear and angular momentums to generate the rigid body equations of motion in terms of the Cartesian coordinates of a dynamically equivalent constrained system of par

11. Load support capacity of a latosol cultivated with coffee plantation under associated methods of weed control / Capacidade suporte de carga de um latossolo submetido a mÃtodos associados de controle de plantas daninhas em cafeeiros.
The control of weeds plants in the coffee plantation can be made through chemical and mechanical methods, which could promote alterations in the soil structure. The objectives of this study were: a) to develop bearing capacity models, for a Yellow Red Latosol cultivated with coffee, as a function of the associated methods of weed control, preconsolidation pr

12. Study of the mechanical behaviour of mouth protectors prepared with ethylene and vinyl acetate copolymer: experimental model of dental arches produced with epoxy / "Estudo do comportamento mecânico de protetores bucais confeccionados em copolímero de etileno e acetato de vinila: modelo experimental de arcos dentais obtidos em epóxi"
An experimental model of dental arch, moulded in epoxy, was used to study the mechanic behaviour of a copolymer of ethylene and vinyl acetate (EVA), in the form of a flat plaque or mouth protector in function of three variables: thickness, temperature and the absence or presence of artificial saliva. The evaluation of the mechanical behaviour of EVA, as a pl
