1. NMR Relaxometry Applied to Chemical Studies of Paramagnetic Metal Cation Complexes: Fundamentals and Applications
Low field time-domain nuclear magnetic resonance (TD-NMR) relaxometry of paramagnetic metal cations (PMC) has been widely used to study and improve contrast agents for magnetic resonance imaging (MRI). However, despite its remarkable potential, TD-NMR is rarely used to study PMC complexes, and coordination compounds in non-biomedical application. Therefore,

2. Internet of Things as a Tool for Sustainable Analytical Chemistry: A Review
Sustainable analytical methods are highly demanded in the modern society. Within the green principles, novel procedures that attend the sustainable development goals have been proposed and the internet of things (IoT) can play key role to achieve this goal. The association of IoT with analytical chemistry enables the real-time obtaining of analytical data to

3. Cascade Modeling of the Measuring System Used to Assess S-Parameters of Anchor Rods on Power Transmission Lines Guyed Towers
Abstract The structural condition of the cable-stayed towers anchorage on power transmission lines requires constant monitoring. Maintenance routines must be able to identify faulty anchor rods and substitute them to avoid tower collapses and power delivery interruptions. Modern statistical diagnostic systems based on machine learning requires the generation

4. REPLY TO “COULD SIGN-BASED SEMANTICS AND EMBODIED SEMANTICS BENEFIT ONE ANOTHER?”
Abstract Sign-based semantics and embodied semantics are argued to be mutually beneficial to one another. However, while the body does shape our cognitive activities to a great extent, this does not entail that cognition can be reduced to sensorimotor simulation, i.e that the mind can be reduced to the body. Language itself bears testimony to this, as the mi

5. Consumer awareness of food antioxidants. Synthetic vs. Natural
Abstract Food antioxidants are a core topic of food science due mainly to the consumption of ultra-processed foods, which cannot be overlooked, and represent an importance to modern society. At the same time, natural food antioxidants are gaining attention in studies due to its food safety aspects, that commonly affect food choices. Based on this, the presen

6. Transcatheter Aortic Valve Implantation: Where are we in 2020?
Abstract Aortic stenosis is an insidious disease of rapid progression after the onset of symptoms. Aortic valve replacement surgery is a well-established therapy that reduces symptoms and increases survival rates. However, the procedure may be associated with high operative mortality rates and promote comorbidity. Depending on the local reality, the prevalen

7. A HISTÓRIA DA CIÊNCIA COMO “REMÉDIO” NO ENSINO DE QUÍMICA: EPISÓDIO - ESTUDO SOBRE A INVENÇÃO DA TEORIA ATÔMICO-MOLECULAR MODERNA
In recent years, much has been said about the approach of the history of science and science teaching. We know that this approach can be made using historical episodes in science classes. In this sense, this work aims to bring a historical episode to be worked on in general chemistry classes in high school, as well as in general chemistry classes 1 of univer

8. Synthesis and Evaluation of the Fungal Activity of New Pyrazole-Carboxamides against Colletotrichum gloeosporioides
The pyrazole core has been recognized by their biological properties and included in the synthesis of modern agrochemicals. Part of these studies consists of making structural modifications to pesticides for commercial purposes to increase efficacy. In this article, we present the synthesis of four new pyrazol-4-carboxamide 8a-8d derivatives (PCD), through a

9. THE BIPOLARITY OF DEMOCRACY AND AUTHORITARIANISM: VALUE PATTERNS, INCLUSION ROLES AND FORMS OF INTERNAL DIFFERENTIATION OF POLITICAL SYSTEMS
Resumo O artigo começa com a observação de que a sociedade mundial de hoje exibe uma bipolaridade em seu regime político e sugere uma interpretação baseada nas teorias sociológicas da inclusão e diferenciação funcional. Assim, (1) distinguimos os regimes políticos entre democráticos e autoritários, identificando os padrões valorativos subjacent

11. EXPERIÊNCIAS DO TEMPO FUTURO ATRAVÉS DA FICÇÃO CIENTÍFICA: ANÁLISE DAS MUDANÇAS DE PERCEPÇÃO DO PORVIR DA GUERRA FRIA AO SÉCULO XXI
Resumo A partir das reflexões sobre o conceito de presentismo, de François Hartog, este artigo busca identificar os sinais do surgimento de um "regime moderno de historicidade" em obras de ficção científica produzidas entre o início da Guerra Fria e 2017. Defendemos que, gradativamente, filmes e livros do gênero foram apresentando futuros cada vez mai
