This study suggests that FHP is not associated with PPTs in asymptomatic university students. In university students with subclinical neck pain, increased FHP was associated with right trapezius hypoalgesia and with neck pain of shorter duration. These findings are in contrast with current assumptions on the association between neck pain and FHP.

Drought is a limiting factor for agricultural productivity. Climate change threatens to expand the areas of the globe subjected to drought, as well as to increase the severity and duration of water shortage. Plant growth-promoting bacteria (PGPB) are widely studied and applied as biostimulants to increase plant production and to enhance tolerance to abiotic and biotic constraints. Besides PGPB, studies on the potential of nanoparticles to be used as biostimulants are also thriving. However, many studies report toxicity of tested nanoparticles in bacteria and plants in laboratory conditions, but few studies have reported effects of nanoparticles towards bacterial cells and communities in the soil. The combined application of nanoparticles and PGPB as biostimulant formulations are poorly explored and it is important to unravel the potentialities of their combined application as a way to potentiate food production. In this study, Rhizobium sp. E20-8 and graphene oxide (GO) nanosheets were applied on container-grown maize seedlings in watered and drought conditions. Bacterial survival, seedling growth (dry weight), and biochemical endpoints (photosynthetic pigments, soluble and insoluble carbohydrates, proline, lipid peroxidation, protein, electron transport system, and superoxide dismutase) were evaluated. Results showed that the simultaneous exposure to GO and Rhizobium sp. E20-8 was able to alleviate the stress induced by drought on maize seedlings through osmotic and antioxidant protection by GO and mitigation of GO effects on the plant’s biochemistry by Rhizobium sp. E20-8. These results constitute a new lead on the development of biostimulant formulations to improve plant performance and increase food production in water-limited conditions.

The article reports a workshop of performing experience on Computational Thinking aimed at higher education teachers. The workshop aimed to sensitize teachers about the application possibilities of this thinking model in educational activities in different areas of knowledge. First, the concept of Computational Thinking is presented as defined by Wing (2006 and2008). Then the text describes the workshop objectives, the topics and the practical activity performed with the participants, based on a visual framework of organizing procedures for troubleshooting created especially for the occasion of the course. The results of the workshop observed based on a survey of the participants are presented in the last section. Resumo. O artigo relata a realização de oficina sobre PensamentoComputacional destinada a professores do ensino superior. A oficina teve como principal objetivo sensibilizá-los sobre as possibilidades de aplicação deste modelo de pensamento em atividades educacionais de diferentes áreas do conhecimento. O conceito de Pensamento Computacional é apresentado segundo a definição de Wing (2006Wing ( e 2008. Em seguida, são descritos os objetivos da oficina, os tópicos abordados e a atividade prática realizada com os participantes, baseada em um framework visual de organização de procedimentos para a solução de problemas, criado especialmente para a ocasião do curso. Os resultados da oficina, observados com base em uma pesquisa com os participantes, são apresentados na última seção.
