Enzyme endo-β-mannanase is associated with the poor physiological quality of coffee seeds Coffea arabica L.

Endo-β-mannanase enzyme activity may indicate poor physiological quality of dried Coffea Arabica L. coffee seeds. This was the conclusion of a study conducted by researchers of the Brazilian Agricultural Research Company Embrapa Café, in Brasília, in partnership with researchers from the Federal University of Lavras, in Lavras, Minas Gerais, Brazil.

Co-word analysis applied to highly cited papers in Library and Information Science (2007-2017)

The conceptual structure in the category Library Science and Information Science of Web of Science, in the period 2007-2017, is identified, using the analytical tool Essential Science Indicators (ESI). Based on highly cited papers, the methodology consisted in the application of co-words analysis and multivariate analysis techniques and visualization through science mapping. Read More →

Is physical exercise beneficial even in malnutrition?

It was demonstrated that physical exercise have benefits against malnutrition. Weight loss, known as the biggest feature of malnutrition, was reversed. Oxidative stress markers in the liver and blood, and liver health indicators that are known to be affected by malnutrition were also improved. Yet, how could exercise be beneficial to a “sick” organism? Read More →

The organization of the knowledge of humanity is fundamental for the survival of Society

We study the theoretical intersections between foundational authors on classification and indexing that helped developing the theoretical-methodological framework of knowledge organization. We highlight and analyze the theoretical convergences of Harris, Dewey, Cutter, Otlet, Kaiser, and Ranganathan to clarify the historical and theoretical contributions to the epistemological foundations of knowledge organization.

Electrostatic interaction determines protein coating of alginate microparticles by ionic gelation

Varying the pH significantly influences the protein coating of alginate microparticles by ionic gelation and consequently the protection and release of the encapsulated material. Varying the amount of calcium, on the other hand, did not show influence protein adsorption during the coating phase with a protein layer. These were the results found by researchers from the Federal Technological University of Paraná, in Londrina, and from the Institute of Food Technology, Campinas, São Paulo, Brazil. Read More →

What is the impact of asthma on the quality of life of parents and caregivers of children who have the disease?

This study aimed to evaluate the levels of quality of life of parents and caregivers of children diagnosed with asthma. The results demonstrate that the quality of life of individuals who take care of asthmatic children are significantly inferior compared to those responsible for healthy children or even children with asthma remission due to the care the disease requires.

Methodology for development of “in-house indicators” for scholarly journals in consolidation

Adherence to quality criteria required by indexing agencies is an essential condition for managers in order to achieve performance success of scientific journals under their responsibility. In a recent study researchers verified and tested “household indicators” for journals still under consolidation, based on data sources under the grasp or domain of such managers. Read More →

How to produce in vitro plants from scutellum of immature Brazilian wheat embryos

Researchers adapted an in vitro culture regeneration protocol for Brazilian wheat genotypes testing different concentrations of growth regulators 2,4-D and picloram. They also found that BR18-Terena and PF020037 wheat genotypes are the most adaptable for in vitro regeneration by somatic embryogenesis. Read More →

Are eating disorders linked to transmission by parents of high anxiety attachment models?

One study aimed to investigate in eating disorders (ED) patients the prevalence of High Anxiety Attachment Internal Working Models (HAIWMs) and their transmission by parents. The Separation Anxiety Test was administered to 55 patients with an ED, a control sample, their mothers and fathers. The two groups differed significantly, with a prevalence of HAIWMs in the patients and their parents compared to the controls. Read More →
