Assessment of bias and associated factors for food portion quantification with photos in Brazil
(2021) [Artigo de periódico]Background: Food portion size estimation is an important source of error in obtaining dietary data. While food portion photos are known to aid the food portion estimation, the validation of photos are required. Objective: ... -
Ontology for healthcare AI privacy in Brazil
(2024) [Artigo de periódico]Este artigo detalha a criação de uma nova ontologia de domínio na intersecção entre epidemiologia, medicina, estatística e ciência da computação. Ele delineia uma abordagem sistemática para o tratamento de dados estruturados ... -
Differential geometry using quaternions
(2024) [Artigo de periódico]This paper establishes the basis of the quaternionic differential geometry (HDG) initiated in a previous article. The usual concepts of curves and surfaces are generalized to quaternionic constraints, as well as the curvature ... -
Um panorama da catálise no Brasil nos últimos 40 anos
(2017) [Artigo de periódico]In this work, the catalysis area in Brazil is analyzed from several perspectives between 1977 and 2017. The conceptual aspects and the area at world level are briefly introduced. A history of the main organizational ... -

(2017) [Artigo de periódico]This article assesses the intention of chemistry teachers to integrate digital media in their classes. The evaluation was performed using a structured questionnaire after participation in two professional development ... -
A metodologia de resolução de problemas : uma experiência para o estudo das ligações químicas
(2018) [Artigo de periódico]This article presents an experience of the use of the Problem Solving(PR) methodology with undergraduate students of the Licentiate Course in Chemistry of UFRGS, for the study of Ionic Bonding(LI). Salarde Uyuni salts were ... -
Computing the characteristic polynomial of threshold graphs
(2014) [Artigo de periódico]We present an algorithm for constructing the characteristic polynomial of a threshold graph’s adjacency matrix. The algorithm is based on a diagonalization procedure that is easy to describe. It can be implemented using ... -
Late-time constraints on interacting dark energy : analysis independent of H0, rd, and MB
(2024) [Artigo de periódico]We investigated a possible interaction between cold dark matter and dark energy, corresponding to a well-known interacting dark energy model discussed in the literature within the context of resolving the Hubble tension. ... -
Energies of hypergraphs
(2020) [Artigo de periódico]In this paper, energies associated with hypergraphs are studied. More precisely, results are obtained for the incidence and the singless Laplacian energies of uniform hypergraphs. In particular, bounds for the incidence ... -
