1. Determination of acoustic fields in acidic suspensions of peanut shell during pretreatment with high-intensity ultrasound
Abstract The benefits of high-intensity ultrasound in diverse processes have stimulated many studies based on biomass pretreatment. In order to improve processes involving ultrasound, a calorimetric method has been widely used to measure the real power absorbed by the material as well as the cavitation effects. Peanut shells, a byproduct of peanut processing

2. Development of ultrasonic waveguide for monitoring dental implant osseointegration / Desenvolvimento de guia de ondas ultra-sônicas para monitorar a osseointegração de implantes dentários
Available equipments for clinical assessment of dental implants monitor changes in stiffness but are not able to quantify the osseointegration level. Literature shows that the application of low-intensity pulsed ultrasound stimulates the healing of bone fractures and the bone ingrowth into implants pores, indicating that an ultrasonic waveguide could be used

3. Avaliação do processo de cicatrização de lesões, tratadas com laser de baixa intensidade, através de sistema de aquisição e tratamento de imagem
Wound healing is a complex dynamic process characterized as a sequence of responses from several types of cells (epithelial, inflammatory, blood platelet, and fibroblasts) that interact to restore tissue complexion. It starts right after occurring an injury with an inflammatory stage, which is followed by granulation and, finally, by epithelization. Several

4. Efeitos da radiação ultra-sônica pulsada e de baixa intensidade sobre o mal perfurante plantar (MPP), manifestação cutânea decorrente da Hanseníase / Effects of the low intensity pulsed ultrasound on the Hansens perforating plantar disease (MPP), cutaneous manifestation from Hansens disease
Diante de pesquisas realizadas com o 5Ultra-som pulsado de baixa intensidade na regeneração de pele de ratos submetidos a queimaduras provocadas por calor (ALVES, 1988) e em pacientes portadores de úlceras tróficas de perna (HILÁRIO, 1993) se propôs estudar os efeitos do ultra-Som pulsado de baixa intensidade em pacientes com Mal de Hansen (MH) cujas m

5. Quantitative assessment of the germicidal efficacy of ultrasonic energy.
Propagated (free-field) ultrasonic energy at a frequency of 26 kHz was used to expose aqueous suspensions of bacteria (Escherichia coli, Staphylococcus aureus, Bacillus subtilis, and Pseudomonas aeruginosa), fungus (Trichophyton mentagrophytes), and viruses (feline herpesvirus type 1 and feline calicivirus) to evaluate the germicidal efficacy of ultrasound.
