1. Evaluation of the Properties of LaNiO3 Material Prepared by the Modified Proteic Method for Adsorption of Environmental Contaminants
LaNiO3 material was synthesized by modified proteic method, calcined at 900 °C/2 h in air atmosphere and was applied to remove environmental contaminants. LaNiO3 phase with a perovskite structure was formed in the calcined material, which has a surface area of 22 m2 g-1 and is formed by fine particles agglomerated, with pH of the zero charge point of 7.44.

2. FUZZY MODELING OF SALINITY EFFECTS ON PUMPKIN (Cucurbita pepo) DEVELOPMENT
ABSTRACT The low quality of the water currently used for irrigation purposes harms the quality of the products and can lead to a reduction in production. Thus, the objective of this work was to verify the effect of saline water in irrigation water, on biometric variables of pumpkin crop using a system based on fuzzy rules. The agronomic experimental part of

3. Urethral monopolar cauterization: alternative infravesical obstruction model in male rats
SUMMARY OBJECTIVE: We aimed to determine which method gives the most consistent results between urethral monopolar cauterization and standard urethral partial ligation methods for the urethral obstruction model. METHODS: Thirty male rats were randomly divided into control, partial ligation, and monopolar cauterization groups. Six weeks after experimental p

4. Derivation and validation of a national multicenter mortality risk stratification model - the ExCare model: a study protocol
Abstract Introduction Surgical care is essential for proper management of various diseases. However, it can result in unfavorable outcomes. In order to identify patients at higher risk of complications, several risk stratification models have been developed. Ideally, these tools should be simple, reproducible, accurate, and externally validated. Unfortunate

5. A 2.4 GHz Coplanar Solar Cell Patch Antenna with a Semi-Analytical Evaluation of Temperature Effects
Abstract Solar cells integrated with antennas have aroused scientific interest as an attractive energy source alternative in low power devices for IoT and Wireless Sensor Network applications. Since the space for all components in the systems is scarce, different integration ideas have been proposed in this field. However, further analysis of the performance

6. Methodology for evaluation of the influence of roughness and capillary absorption of ceramic blocks on the render’s tensile bond strength
Abstract The literature indicates that it is difficult or even impossible to associate with strong statistical confidence the bond strength of a mortar coating with the properties of the ceramic block, such as roughness and water absorption. In this work, it is assumed that the variability in capillary water absorption and roughness, and the use of methods t

7. Evaluation of platelet indices and pro-inflammatory cytokines in type 2 diabetic patients with retinopathy
SUMMARY OBJECTIVE: The aim of this study was to investigate whether platelet parameters and pro-inflammatory cytokines associated with platelet activation could be surrogate markers of the diabetic retinopathy stages in type 2 diabetic patients. METHODS: This prospective case-control study included 108 type 2 diabetes mellitus patients and 48 healthy contr

8. Evaluation of the Current in the Cell Membrane for Numerical Simulations of Electroporation
Abstract This study presents a rigorous numerical analysis of the current in the cell membrane, subjected to a uniform electric field, and its impact in the pore formation. The numerical model considers a single cell composed of uniform membrane and cytoplasm, in a suspension medium. The current in the cell membrane is calculated using two different approach

12. Assessment Protocol for Candidates for Bone-Anchored Hearing Devices
Abstract Introduction The technology regarding bone-anchored hearing devices has been advancing. Nevertheless, complications are still often reported, which can impair treatment adherence and lead to discontinuation of use. There is a lack of studies conducted in tropical countries, where complications can be even greater, as well as standardized protocols
