Gestão da Manutenção Centrada na Confiabilidade em Pontes Rolantes

The objective of this work is to perform a study applying the methodology of Reliability Centered Maintenance - MCC to a group of cranes belonging to Amsted -Maxion in Cruzeiro - SP. The work consists of a presentation of maintenance, the reasons why more and more people worry about maintenance, making a presentation on the types of maintenance, its peculiar characteristics and then do a study where you identified the functionality required by the equipment under study, identified failure modes and their probable causes, and then detail the effects and consequences of these failures. With that evaluate the criticality of these failures and identify the most significant consequences that affect safety, availability or cost of equipment operation and allow a selection of the most appropriate tasks for the identified failure modes. We will also present best crane equipment, its main components, verify that there was or not improvement in the machine after the application of MCC and make a current analysis of maintenance in Amsted -Maxion

Estudo sobre o funcionamento de sistema de controle de tração em veículos automotores

This study explores the subject of traction control systems through bibliografy review on the spot of Mechanical Engineering. This paper has the objetivo of high light the main components and tecnology involved since MaxTrac system in 1971. It describes systems controled by throttle valve and breaks. Additionally, it i also presented basic knowlodged regarding electronic control unit and wheel sensors

Loss of electricity and refrigerated foods: avoiding the danger zone

Recent events such as Winter Storm [Hurricane] Sandy and Hurricane Katrina have demonstrated that local food supplies must last as long as possible. Current recommendations are to dispose of all refrigerated food four hours after the power is lost. The purpose of this study was to determine if it is possible to safely hold food longer than four hours without power. The results indicate that the food can be held for up to six hours if the door is not opened. If ice is added to the refrigerator, then it will take the food approximately 10 hours to reach 5°C (41°F).

Rugosidade superficial e adesão bacteriana em compósitos com nanopartículas após acabamento e polimento

Objective: To evaluate in vitro the surface roughness and bacterial adhesion of nanoparticle composites, after being subjected to different finishing and polishing systems. Materials and Methods: 66 specimens were prepared, and 30 with Filtek Z350 XT (3M ESPE, USA) and 30 with the resin IPS Empress Direct (Ivoclar Vivadent, USA), divided into 6 groups (n = 10 ). Six specimens were prepared for analysis in scanning electron microscopy (SEM) .Each kind of resin was subjected to finishing and polishing systems: Sof-Lex Pop-On discs (3M ESPE, USA) and AstropolTM system (Ivoclar Vivadent , USA), featuring the experimental group. The control group did not undergo any kind of finishing and polishing technique. The average roughness (Ra) in both groups was measured using a roughness in the setting of 0.25 mm (cut off) and surface images obtained with photomicrographs taken with a scanning electron microscope (SEM) magnified 500 times. Bacterial adherence was evaluated by determining the absorbance (OD) of the suspension of adhered cells by spectrophotometer at 570 nm. The results were submitted for analyzed with 2-way ANOVA at α=.05 and Tukey multiple comparison tests. Results: Statistically significant differences were found between the groups in terms of roughness and bacterial adhesion. Filtek Z350 XT for resin were no differences between the tested finishing and polishing systems, where the system of lowest surface roughness was the Sof-Lex Pop-On. To the resin IPS Empress Direct, the finishing and polishing system Astropol, had lower results of surface roughness. As for bacterial adhesion, the lowest optical density value for Filtek Z350 XT was for the group that used the finishing and polishing system Sof-Lex Pop-On and the resin IPS Empress Direct the group that used the Astropol system. In addition, there was a positive correlation between surface roughness and bacterial adhesion on polished surfaces (r = 0.612) Conclusions: surface roughness and bacterial adhesion are closely related. The finishing and polishing Sof-Lex Pop-On system is more suitable for nanoparticulate Filtek Z350 XT and the finishing and polishing system Astropol for resin nanohíbrida IPS Empress Direct.
