13. IMAGINATION, RELIGION, LANGUE Trois vecteurs de la révolution pédagogique fichtéenne des Discours à la Nation Allemande
ABSTRACT By allowing the intellection of a universal horizon for the human kind, education has found its place in the anthropological core of Enlightenment. Strongly influenced by this conceptual frame in his youth, Fichte has however witnessed the limits of this pedagogical paradigm when it comes to understanding the historical processes of collective learn

14. Synthesis and Biological Evaluation of Benzo[f]indole-4,9-diones N-Linked to Carbohydrate Chains as New Type of Antitumor Agents
In this work, we report the synthesis of three series of carbohydrate-based benzo[f]indole-4,9-diones and amino-1,4-naphthoquinone derivatives and evaluated their cytotoxic activity against eight human cancer cell lines. Several compounds showed a promising cytotoxic activity toward the tumor cell lines (half maximal inhibitory concentration (IC50) < 10.0 μ

15. Non-Ionizing Radiation Analysis in Close Proximity to Antenna Tower: A Case Study in Northeast Brazil
Abstract While the amount of telecommunications services grows rapidly in the whole world, humans get potentially more exposed to Non-Ionizing Radiation (NIR) from a number of different sources. Measurements of NIR levels are relevant in order to compare the results with national and international standards, aiming at the preservation of human health. Thus,

16. Evaluation of the Direct Interaction between Amino Acids and Glutathione-Coated CdTe Quantum Dots and Application in Urinalysis for Histidine Determination
The present work aimed to direct amino acid (AA) sensing by quantum dots (QD) and development of an analytical method for potential fast clinical tests. Notably, AA with a positive charge or neutral polar chains, namely L-histidine (His) and L-threonine (Thr), responded to glutathione-coated CdTe (GSH-CdTe) (ΔF ≤ 90%, variation of fluorescence intensity).

17. POLÍMERO DE IMPRESSÃO MOLECULAR PARA O TIACLOPRIDO: UMA INVESTIGAÇÃO TEÓRICA
Thiacloprid (TCP) is a synthetic insecticide, belonging to the class of neonicotinoids (NNCs), which present potential damages to the environment, biodiversity and human health, being necessary its constant monitoring. In this sense, molecularly imprinted polymers (MIPs) have been shown as an excellent alternative for the separation science, since they can r

18. Development of diet cereal bar sweetened with stevia leaves pre-treated with ethanol
Abstract The objective of this work was to perform the ethanolic pretreatment of stevia leaves from the plant Stevia UEM-13 line and to characterize its physical-chemical properties aiming its use as a sweetener in the development of a diet cereal bar. The same formulation of the cereal bar with stevia leaves without pretreatment was elaborated for comparati

19. Identification of Potential Inhibitors of Severe Acute Respiratory Syndrome-Related Coronavirus 2 (SARS-CoV-2) Main Protease from Non-Natural and Natural Sources: A Molecular Docking Study
So far, there is neither a vaccine nor a specific antiviral drug to prevent or treat COVID-19 (coronavirus disease) infection. Recent studies have been done to investigate the capacity of human immunodeficiency virus type 1 (HIV-1) protease inhibitors be used in the treatment of COVID-19 patients. Some of those drugs have shown to be promising. Natural chemi

20. LO SPIRITO MANIFESTATORE, NELLA PNEUMATOLOGIA DI PAVEL N. EVDOKIMOV
ABSTRACT The new, pneumatic, person is central to Pavel N. Evdokimov’s (1901-1970) theological work. He argues that the Holy Spirit’s action is not understandable with an exclusively objective analysis of God’s action in relationship to humanity. Rather, the human person welcomes the gifts of the Holy Spirit within a double movement: the first phase is

21. IMPACTOS DOS BTEX EM ÁREAS URBANAS DA CIDADE DO RIO DE JANEIRO
Most volatile organic compounds (VOC) have adverse effects on human health and the environment and react individually with different velocities and mechanisms to form ozone. The present work determined the concentration of 55 samples of benzene, toluene, ethylbenzene and xylenes (BTEX), an important subgroup of VOC, by active sampling with active carbon cart

22. Ageing in organizations
Abstract Purpose This paper aims to show which factors influence the perception of human resources professionals about managers over 50 years old and which factors guide the age management practices adopted in the surveyed companies. Design/methodology/approach To this end, a survey was conducted with 140 companies accessed from a database of a human resou

23. Establishment of a simple and efficient platform for car-t cell generation and expansion: from lentiviral production to in vivo studies
ABSTRACT Introduction: Adoptive transfer of T cells expressing a CD19-specific chimeric antigen receptor (CAR) has shown impressive response rates for the treatment of CD19 + B-cell malignancies in numerous clinical trials. The CAR molecule, which recognizes cell-surface tumor-associated antigen independently of human leukocyte antigen (HLA), is composed by

24. Microwave Assisted Synthesis of Thiocarbamoylpyrazoles and Application as an Alternative Latent Fingermark Developers
Fingerprints are unique to each individual, contributing to human identification in forensic cases. The powder technique being widely used is considered one of the most important in latent fingermarks analysis. In this sense, the present work aimed to synthesize 1-thiocarbamoyl-4,5-dihydro-1H-pyrazoles and apply them as powder agents to develop latent finger
