1. Are hemoglobin-derived peptides involved in the neuropsychiatric symptoms caused by SARS-CoV-2 infection?
Follow-up of patients affected by COVID-19 has unveiled remarkable findings. Among the several sequelae caused by SARS-CoV-2 viral infection, it is particularly noteworthy that patients are prone to developing depression, anxiety, cognitive disorders, and dementia as part of the post-COVID-19 syndrome. The multisystem aspects of this disease suggest that mul

2. Settlement of bored piles with expander body system in lateritic soils
Abstract The Expander Body pile (EB) is a combination of a cast-in-situ pile method with an inflated, pump-grouted tip. The EB system's pioneering conjunction with the conventional drilling pile technique has improved work load, foundation security, cost reductions and abrupt displacements in lateritic, porous, unsaturated soils. The aim of this article is t

3. DIRECT CONNECTION PHOTOVOLTAIC SYSTEM IN MULTI-MOTOR APPLICATION FOR THE RURAL SECTOR
ABSTRACT Photovoltaic pumping systems equipped with variable speed drive have been consolidated as an alternative for water supply in rural locations where energy services are unavailable. Such systems are of the direct connection type and, therefore, it is likely that their operation occurs in two situations: when energy is available and when the reservoir

4. Alternative method of sowing canola hybrids using adhesive tape
ABSTRACT Canola, which has tiny oil-producing seeds, requires care during planting, so that there is an ideal number of plants. The aim of this study is to evaluate alternative method of sowing using adhesive tape and the influence it has on the emergence and vigor of the seedlings of different canola hybrids and define the best positioning of the adhesive t

5. Top 10 evidence-based recommendations from the Brazilian Society of Infectious Diseases for the Choosing Wisely Project
ABSTRACT The Choosing Wisely Initiative aims to collect statements from medical societies all over the world on medical interventions that result in no benefit to patients, with the potential to cause harm. In this article we present the views of the Diagnostic Laboratory Group at the Brazilian Society of Infectious Diseases (SBI). Ten experts from SBI were

6. Avaliação teórico-experimental da resistência à compressão de concretos através de ensaios não destrutivos
RESUMO Na avaliação de estruturas degradadas é comum a necessidade de se determinarem propriedades mecânicas de estruturas de concreto sem dispor dos dados de projeto. Propriedades como resistência à compressão e módulo de elasticidade, por exemplo, são importantes nessa análise. No entanto, a extração de testemunhos para avaliação laboratorial

7. SOIL COMPACTION AND THE STABILITY OF LEVEES OF AQUACULTURE PONDS
ABSTRACT The aim of this work was to evaluate the effects of variations in soil compaction on the stability of the slope embankments of fish farms used in aquaculture. Computational modeling was performed using the RocScience Slide 6.0 program, simulating filling scenarios, fast lowering and stationary regimes for the full operation of the fish farms. The da

8. Exames laboratoriais da Pesquisa Nacional de Saúde: metodologia de amostragem, coleta e análise dos dados
RESUMO: Introdução: O artigo teve o objetivo de descrever a metodologia de coleta dos dados dos exames laboratoriais da Pesquisa Nacional de Saúde (PNS). Metodologia: Foi selecionada uma subamostra de 25% dos setores censitários, obedecendo à estratificação da amostra da PNS, com probabilidade inversamente proporcional à dificuldade de coleta. A co

9. Revisão sobre ensaios acelerados para indução da corrosão desencadeada por cloretos em concreto armado
Resumo A corrosão de armaduras desencadeada por cloretos é um dos principais problemas que afetam as estruturas de concreto armado. Considerando o estudo desse tipo de problema, a velocidade na coleta dos dados, a possibilidade de controle das variáveis que influenciam o processo de corrosão e o baixo custo na realização dos testes têm sido aspectos m

11. HYBRID SOLAR HEAT PUMP SYSTEM FOR WATER HEATING
ABSTRACT A comparative test of water heating between the hybrid system - solar collector with heat pump - and a system with conventional supplementary heating - with high electric power - was performed. For this, a small capacity heat pump was installed, which was later installed together with a solar heating system, composed of a 250 L thermal reservoir and

12. Analysis of tRNA halves (tsRNAs) in serum from cattle challenged with bovine viral diarrhea virus
Abstract Acute infections of bovine viral diarrhea virus (BVDV) lead to a range of clinical presentations. Laboratory tests for detection depend on collection of samples during a short viremia. Acutely infected animals remain largely undiagnosed. Transfer RNA halves (tsRNAs) are hypothesized to function like microRNAs to regulate gene expression during an im
