13. Does laser diode irradiation improve the degree of conversion of simplified dentin bonding systems?
Abstract Simplified dentin-bonding systems are clinically employed for most adhesive procedures, and they are prone to hydrolytic degradation. Objective This study aimed to investigate the effect of laser diode irradiation on the degree of conversion (DC), water sorption (WS), and water solubility (WSB) of these bonding systems in an attempt to improve the

14. Physical and chemical quality, biodiversity, and thermodynamic prediction of adhesion of bacterial isolates from a water purification system: a case study
ABSTRACT The objective of this study was to evaluate the quality of water purification system and identify the bacteria this system, predict bacterial adherence according to the hydrophobicity of these microorganisms and of the polypropylene distribution loop for purified water. The assessment of drinking water that supplies the purification system allowed g

16. Correlation between Onset Oxidation Temperature (OOT) and Fourier Transform Infrared Spectroscopy (FTIR) for monitoring the restabilization of Recycled Low-density Polyethylene (LDPE)
In this work a new method was developed for monitoring the oxidative stability of restabilized and non-restabilized low-density polyethylene (LDPE) during multiple extrusion cycles. The method is based on correlations between Fourier Transform Infrared spectroscopy (FTIR) and Onset Oxidation Temperature (OOT). Non-linear calibration curves correlating the co

17. Contribuição para calibração de curva de evolução de afundamentos em trilha de roda de revestimentos asfálticos com utilização de resultados obtidos de simulador de tráfego em escala real. / A contribution to the calibration of performance curves for the prediction of permanent deformation in asphalt pavements using the results obtained from a large scale mobile traffic simulator
Permanent deformation, or rutting, is a critical type of pavement distress given that it is directly associated with transportation costs, due to a reduction of the ride quality, and user safety, due to poor driving conditions or water build-up during rainy periods that affect the tire-pavement interaction. In the case of pavements of highways belonging to c

18. Dairy cow monitoring by RFID
Dairy cows identification and monitoring on small cattle farms are usually based on the utilization of barcode technology. This kind of identification technology is unsuitable for dairy cows milking and feeding process automation. Radio Frequency Identification (RFID) technology is a better solution in this case. This paper describes the research and impleme

20. The assessment of infection control in dental practices in the municipality of São Paulo
OBJECTIVE: The goal of this study was to evaluate the infection control measures actually implemented by dental surgeons during dental practice, as patients and professionals are exposed to high biological risk in dental care environments. METHOD: 614 questionnaires (90.69%) were answered by professionals registered in updating or in post-graduate courses in

21. Desenvolvimento das barras imunosorventes de agitação e avaliação das técnicas extração sortiva em barra de agitação, microextração em sorvente empacotado e cromatografia líquida para análise de antidepressivos em amostras de plasma / Development of immunosorbent stir bars and evaluation of stir bar sorptive extraction, microextraction by packed sorbent and liquid chromatography for the analysis of antidepressants in plasma samples
In this work, polyclonal and monoclonal anti-fluoxetine antibodies were developed in rabbits and mice by immunization with fluoxetine-bovine albumin conjugate, respectively. The developed antibodies were characterized on the basis of the specificity against the drug by ELISA (enzyme linked immunosorbent assay) and, subsequently they were purified by labmade

22. Assessment of polarimetric ALOS PALSAR data for Amazon land cover classification / Avaliação de dados polarimétricos do sensor ALOS PALSAR para classificação da cobertura da terra da Amazônia
Amazon Forest is considered the largest tropical forest of the planet. It keeps considerable part of the biodiversity and has great importance to the biogeochemistry cycles. The anthropic actions cause destructive processes such as deforestations and burnings, which can provoke unbalances on the ecosystem. This scenario highlights the importance of the monit

23. Monitoramento da microbiota e dos parâmetros físico-químicos em vinhoto / Monitoring of microbiota and physicochemical parameters in vinasse
The agro-industrial activities are responsible for generating large amounts of liquid waste. In the production of cachaça, the production of vinasse is about 4 times higher than the production of the spirit. Usually, tanks for deposition of vinasse are constructed by the producers to receive the residue from the manufacturing process. The main aim of this w

24. Resistência de Spodoptera frugiperda (Lepidoptera: Noctuidae) a spinosad no Brasil / Resistance of Spodoptera frugiperda (Lepidoptera: Noctuidae) to spinosad in Brazil
Spinosad has been one of the most used insecticides to manage Spodoptera frugiperda (J.E. Smith) in Brazil, due to its high efficacy and unique mode of action (nicotinic acetylcholine receptor allosteric activators). In order to preserve its lifetime, the objectives of this research were: (a) to characterize the geographic and temporal variability in the sus
