1. A Comparison of the Photolytic and Photocatalytic Degradation of Triclosan: Identification of Transformation Products and Ecotoxicity Evaluation
Triclosan (5-chloro-2-(2,4-dichlorophenoxy)phenol) is commonly used as an antibacterial agent in various industrial products and is often detected in wastewater effluent. Comparison was made for triclosan degradation by photolysis and TiO2 photocatalysis (under UV irradiation (125 W)) based on analysis of transformation products, together with ecotoxicity ev

2. Determination of carrageenan in jellies with new methylene blue dye using spectrophotometry, smartphone-based colorimetry and spectrophotometric titration
Abstract Carrageenan is a seaweed polysaccharide widely used as a food gelling and thickening agent. The New Methylene Blue dye was tested as an analytical reagent for the quantification of carrageenan in commercial jelly samples. The main spectral peaks of the dye decrease with increasing carrageenan-to-dye molar ratio up to 1. Three analytical procedures w

3. Agradecimentos aos Pareceristas ad hoc do volume 18 (ano 2020)
According to the World Health Organization (WHO), Chagas disease (CD), whose etiological agent is the Trypanosoma cruzi (T. cruzi) parasite, affects about eight million people, mainly in Latin America. The cruzain enzyme is highlighted among the main biological targets, since it is the most abundant of the cysteine protease class from T. cruzi and is involve

4. Reordering of Depolymerized Silicates as Adsorbents for Large Nitrogen Compounds
The adsorption capacities of two synthesized zeolites (crystalline ZSM-5 and semi-crystalline faujasite Y) for a mixture of indole, quinoline and carbazole were studied. The different samples obtained show different crystalline degree, mesoporosity and Si/Al ratios. The synthesis procedure is based on the simultaneous depolymerization of a mixture of high su

6. COMPUTER SIMULATIONS IN METAPHYSICS: POSSIBILITIES AND LIMITATIONS
Abstract Computer models and simulations have provided enormous benefits to researchers in the natural and social sciences, as well as many areas of philosophy. However, to date, there has been little attempt to use computer models in the development and evaluation of metaphysical theories. This is a shame, as there are good reasons for believing that metaph

7. Reforma da Previdência: sustentabilidade e justiça atuarial
Resumo O artigo analisa a proposta de reforma da previdência social feita pelo governo Temer. Investigamos a sustentabilidade financeira do sistema proposto e a sua justiça atuarial. Consideramos as regras contidas na proposta original do governo. Procuramos dar respostas a duas questões relacionadas: (i) qual deveria ser a alíquota de contribuição par

8. MULTI-AGENT BASED MODELING APPLIED TO PORTFOLIO SELECTION IN THE DOOM-LOOP OF SOVEREIGN DEBT CONTEXT*
ABSTRACT This study explores the self-fulfilling dynamic between sovereign debt risk and rational choices of neutral, risk-seeking and risk-averse investors, with implications to the systemic risk emergence. The agent-based model parameterization includes investment strategy (randomly selected assets, stock exchange participation, economic segment, and techn

9. Molecular Modeling, Structural Analysis and Evaluation of 1-Deoxy-D-Xylulose-5-Phosphate Reductoisomerase (DXR) as a Putative Drug Target For Theileria Parva
ABSTRACT The apicomplexan parasite Theileria parva, the causative agent of ECF, is an important pathogen affecting both domestic and wild animals, causing major economic losses in the world. Problems such as high cost of drugs, development of resistance, and absence of effective vaccines prevent effective combating of the pathogen. Thus, it is necessary to e

10. Extracción optimizada y purificación parcial de invertasa aislada de S. Cerevisiae en puré de durazno
Abstract The extraction was performed using an autolysis process where enzymes degrade cell structures and release the cytoplasmic contents to the extracellular medium. The autolysis process was carried out in shake flasks with different agitation speeds (50 - 350 rpm) and the concentration of sodium bicarbonate (50 -350 mM NaHCO3) at 40 ° C for 24 hours, u

11. Simulating the behavior of patients who leave a public hospital emergency department without being seen by a physician: a cellular automaton and agent-based framework
The objective of this study was to develop an agent based modeling (ABM) framework to simulate the behavior of patients who leave a public hospital emergency department (ED) without being seen (LWBS). In doing so, the study complements computer modeling and cellular automata (CA) techniques to simulate the behavior of patients in an ED. After verifying and v

12. Antigenotoxicity protection of Carapa guianensis oil against mitomycin C and cyclophosphamide in mouse bone marrow
ABSTRACT The aim of this study was to evaluate the possible protective of C. guianensis oil against MMC and CP, which are direct- and indirect-acting chemical mutagens, using the micronucleus test. Three experiments were performed. First the C. guianensis oil was co-administered to mice at doses of 250, 500 and 1000 mg/kg bw with 4 mg/kg bw MMC or 50 mg/kg b
