Microstructural and Electrochemical Study: Pitting Corrosion Mechanism on A390 Al-Si Alloy and Ce-Mo Treatment as a Better Corrosion Protection.

Sulfuric acid anodizing assisted by a hydrothermal sealing with inhibitors [Ce-Mo] was used to prevent pitting corrosion on spray-deposited hypereutectic Al-Si alloy (A390). An investigation concerning the evaluation of pitting corrosion resistance on the anodic oxide thin film with ions incorporated was carried out in NaCl solution using electrochemical measurements (i.e.

Thermal Evaluation of Multi-Antenna Systems Proposed to Treat Bone Tumors: Finite Element Analysis.

Microwave ablation is commonly used in soft tissue tumors, but its application in bone tumors has been barely analyzed. Antennas to treat bone tissue (~3 cm2), has been lately designed. Bone tumors at pathological stage T1 can reach 8 cm wide.

A Computational Evaluation of the temperature distribution generated by thermal splints designed to treat knee pain.

A 3D modeling study was performed to evaluate the temperature distribution produced due to knee thermal splints to facilitate future investigations into the possible relationship between the temperature distribution and the pain relief related performance of the splints. Water and phase change material (PCM) were used as splint fillers at two different temperatures (42 °C and 44 °C). Free cooling and a temperature-controlled thermal splint were also considered.

Sugar Concentration Measurement System Using Radiofrequency Sensor.

A sugar solution measurement system was developed based on the dielectric properties of the sucrose molecule. An ac conductivity and tan δ study as a function of the frequency was performed to find the suitable frequency range for the measuring system. The results indicate that it is possible to obtain a better response of the sensor using the frequencies as the maxima peak in tan δ appears.

Intelligent Spectroscopy System Used for Physicochemical Variables Estimation in Sugar Cane Soils.

The current condition of soils is a major area of interest due to the lack of certainty in their physicochemical properties, which can guarantee the quality and the production of a specific crop. Additionally, methodologies to improve land management must be implemented in order to address the consequences of many environmental issues. To date, many techniques have been implemented to improve the accuracy-and more recently the speed-of analysis, in order to obtain results while in the field.
