13. Association Between Lipid Profile and Clinical Manifestations in Sickle Cell Anemia: A Systematic Review
Abstract Introduction Sickle cell anemia (SCA) is a genetic disease associated with frequent episodes of acute illness. Changes in the lipid profile and a chronic inflammatory process make up the molecular aspects observed in this disease. Associations between these mechanisms and clinical manifestations could thus define severity profiles and therapeutic

14. Mortality in children under five years old in Brazil: evolution from 2017 to 2020 and the influence of COVID-19 in 2020
Abstract Objective: To analyse the mortality trends in children under five years old in Brazil from 2017 to 2020 and the influence of COVID-19 in 2020. Methods: A retrospective study employing secondary data from the Brazilian Mortality Information System. Deaths according to cause were extracted and disaggregated into early, late, post-neonatal, and 1 to

15. Fundamental bioflotation aspects of hematite using an extracted Rhodococcus opacus by-product
Abstract The aim of this study is to assess the floatability of hematite using a crude biosurfactant (BS) extracted from Rhodococcus opacus. Throughout high-pressure ethanol extraction, unrefined surfactant was extracted from the bacteria with a yield of 0.3 g/L. An FTIR analysis on this extract, shows the presence of alcohol (–OH) and ketone (C=O) groups,

16. Thermoelectric properties of barium doped calcium cobaltite obtained by simplified chemical route
Abstract Calcium cobaltite (CCO) thermoelectric ceramics in Ca3Co4O9 and Ca2.95Ba0.05Co4O9 compositions were produced by a simplified chemical route developed in this study. Undoped ceramics sintered at 1193 K for 12 h presented a bulk density equivalent to 77% of the theoretical density, one of the highest values ever found for conventionally sintered undop

17. Escalonamento de tecnologias: desenvolvimento de produto e processo do laboratório à escala piloto conectado ao mercado (parte 1)
In this article, it is described the main aspects to be considered during the process of scaling up hard sciences technologies developed in the Science and Technology Institutes aiming at industrial application. Based on the experience of our group in scaling up, pre-acceleration, and acceleration of different technologies, a methodology was developed and di

18. Inclusion of molecular monitoring (BCR-ABL1) in the treatment of chronic myeloid leukemia in the Brazilian Public Health System (SUS): an urgent need for treatment management
ABSTRACT Introduction: Chronic Myeloid Leukemia (CML) is a myeloproliferative disease that affects mainly adults between 50 and 55 years. In Brazil, information from the Sistema Único de Saúde (SUS) Outpatient Information System indicates that 12,531 patients had the Autorização de Procedimento Ambulatorial (APAC) approved for the CML treatment in 2017.

19. Aqueous Extract of Cumaru (Dipteryx odorata) Seeds as Corrosion Inhibitor for Mild Steel in Hydrochloric Acid Solution
The corrosion inhibition of mild steel by aqueous extract of cumaru (Dipteryx odorata) seeds and its high molecular weight fraction (HMWF) was investigated in 1 mol L-1 HCl solution. The study was carried out through gravimetric essays, open circuit potential measurements, anodic and cathodic polarization curves and electrochemical impedance analyses, as wel

22. NATURAL KINDS AND OUR SEMANTIC INTUITIONS ALONG THE ROAD
Abstract This is a comment on Gómez-Torrente’s approach to natural kinds and natural kind terms. Here I will focus on his concerns related to the arbitrariness argument and his attempt to formulate a reply to it that maintains most (if not all) of the “Kripke-Putnam orthodoxy” when it comes to the reference-fixing of such terms. Gómez-Torrente conclu

23. Synthesis of Sparse Arrays Based On CIGA (Convex Improved Genetic Algorithm)
Abstract In this paper, a novel hybrid algorithm on beam pattern synthesis of sparse arrays is proposed, which aims at minimizing the peak sidelobe level (PSLL). Sparse arrays can provide higher spatial resolution and relatively lower sidelobe than general arrays, but it is necessary to solve the multi-constraint problem of nonconvex nonlinear. Thus, we prop
