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. ADSORPTION OF ATRAZINE IN RICE HUSK BIOCHARS: A PHENOMENOLOGICAL MODEL APPLIED TO EQUILIBRIUM AND KINETIC STUDIES
ABSTRACT Atrazine is an herbicide used to remove weeds in agricultural crops; however, because it is considered toxic, options for removing it from the environment are needed. Adsorption on biochar is an efficient technique for removing organic contaminants. In this study, the atrazine adsorption capacities of two biochars (BCA400 and BCA700) produced from r

3. 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

4. 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

7. Comparison of ultrasonography learning between distance teaching and traditional methodology. An educational systematic review
ABSTRACT BACKGROUND: Use of the web for radiological education is an obvious application. Many computer-based teaching materials have been developed over recent years, and e-learning is becoming increasingly popular in medical schools. OBJECTIVE: To assess whether the effectiveness of distance-learning and/or e-learning, m-learning and web-based methods ar

8. Adhesion evaluation of the Rhodococcus opacus strain on an apatite surface
Abstract Adsorption of microorganisms and/or their different components onto a mineral surface would modify the surface characteristics of the mineral. Thus, this investigation evaluated the adsorption capacity of the Rhodococcus opacus strain onto an apatite surface. Zeta potential and contact angle measurements of the mineral showed dislocations of the val

11. ASSESSMENT OF SOIL LOSS SUSCEPTIBILITY IN SANTA RITA WATERSHED IN SOUTHERN BRAZIL
ABSTRACT Estimation of soil loss susceptibility is of great importance for the management of watersheds. Thus, several models for soil loss prediction have been proposed. This study estimated the total annual soil loss for the Santa Rita watershed, located in southern Brazil, using the Revised Universal Soil Loss Equation. In addition, a classification to so

12. Utilization of the Corncob Agro-Industrial Residue as a Potential Adsorbent in the Biosorption of Bisphenol-A
The presence of plastic waste in water bodies has led to a growing concern due to the impact on human health. Among the most important plastic additive molecules is bisphenol-A (BPA). On the other hand, micro-pollutant removal processes that make use of agro-industrial waste have aroused the interest of researchers. This is because the accumulation of lignoc
