1. Tensile Properties and Fracture Reliability of Melt-extracted Gd-rich Amorphous Wires
Gd60Al20Co20 amorphous wires with smooth surfaces and circular cross-sections were fabricated by a melt-extraction technique. The mechanical properties of the extracted microwires were evaluated by tensile tests and their fracture reliability was estimated by using Lognormal and two- or three- parameter Weibull analysis, respectively. The microwires exhibit

2. ADAPTAÇÃO DA METODOLOGIA DE ANÁLISE DE METEMOGLOBINA COMO BIOMARCADOR DE EFEITO DA EXPOSIÇÃO AO AGROTÓXICO DIFLUBENZURON
This work aimed to adapt the analysis of methemoglobin recommended by Evelyn - Malloy (visible spectrophotometry), in order to facilitate its application in the field, or to analysis in clinical laboratory, of existing sites of diflubenzuron application. The parameters changed included: centrifuge rotation speed; time between the collection of biological sam

3. Case Study: Economic analysis for natural gas operation of cogeneration system in buildings and facilities commercial and dwelling approach through system dynamics / Estudo de Caso: Analise econômica da utilização do gás natural em sistemas de cogeração aplicados a instalações prediais comerciais e residenciais Via Dinâmica de Sistemas
Cogeneration systems must increase the installed brazilian power generation capacity. It can also improve the reliability of the transmission system, using different energy sources in new power plants and enlarging the business opportunities for private capital in the brazilian market. Brazil presents expressive potential for distributed generation plants of

4. Estudo de confiabilidade de compressores alternativos semi-herméticos de sistemas de refrigeração. / Reliability study of reciprocating compressors of refrigeration systems.
Refrigeration systems are reparable systems. This means that one can perform maintenance actions on them several times during the system life cycle. The most common refrigeration system is the vapor compression cycle. In this cycle, the compressor is the most complex and expensive component. So, the user should take special care because , beside problems lik
