1. Evaluation of the Diameter Influence on the Tensile Strength of Pineapple Leaf Fibers (PALF) by Weibull Method
The fiber extracted from pineapple leaf (PALF) displays relevant mechanical properties that are motivating investigations for possible engineering application as polymer composite reinforcement. As any natural lignocellulosic fiber, the PALF presents non-uniform dimensions and heterogeneous properties with a significant dispersion of values. In fact, a marke

2. Corrosão por cloretos em estruturas de concreto armado : uma meta-análise / Corrosion by chlorides in reinforced concrete structures: a meta-analysis
O concreto é o segundo material mais consumido no mundo, perdendo somente para água, justificando a importância de estudos que envolvam seu comportamento frente à durabilidade, e que objetivam a obtenção de estruturas com longas vidas úteis. Dentre as diversas manifestações patológicas que ocorrem nas estruturas de concreto armado, a corrosão das

3. Estudo do ambiente de trabalho em uma fábrica de ônibus : proposta de organização do trabalho em uma empresa semi-artesanal
This study presents as investigation object the employee in the scenery of a bus factory and his/her relation with the labor activities, using the Work Macroergonomic Analysis (WMA) as support. In this sense, the main objective of the thesis was proposing a socio-technical planning model with the effective participation of the workers for the semi artisanal

5. Desenvolvimento de um sistema de aquisiÃÃo e armazenamento de dados microcontrolado
The data acquisition systems are present in many studies, cooperating on collection, storage and analyses of data. On farming field, these systems are used in experiments of agricultural machines, soil characteristics study, as well as in other applications where data collection by sensors is needed. In the present study, a data acquisition system was develo

7. Experimental study of the bistable flow in tube arrays
Flow through circular cylinder arrays are commonly found in several engineering application as offshore structures, heat exchangers, transmission lines and chimneys, therefore the understanding of the several phenomena that occur due the interaction between flowing fluid and these structures is very important. This work analyzes experimentally the presence o

9. Retroanálise probabilista: aplicação prática de análise de percolação em uma barragem de terra. / Probabilistic back-analysis: practical application of seepage analysis in an earth dam.
The engineering project is based upon a model that can predict the behavior of the facility to be constructed. Such model incorporates a series of working hypotheses which may or may not be fully realized during construction or operation. Under such circumstances, probabilistic back-analysis is a powerful tool for continuous evaluation of the working hypothe
