Sistema óptico de projeção a laser para análise da superfície das pregas vocais em imagens laringoscópicas
(Universidade Federal de São Carlos, 2021-09-17)
When understanding the acoustic production of the human voice and its dysphonia, factors such as characteristics and dimensions of the vocal folds are relevant. Previous studies show that images of the glottic surface, ...
Compreendendo o papel da melamina (C3H6N6) no caminho de degradação de compósitos fertilizantes contendo ureia
(Universidade Federal de São Carlos, 2021-11-23)
This work proposed a study of new fertilizer composites that have melamine in their composition, a molecule of high nitrogen content (66% total mass) but recalcitrant, observing factors that may influence the effective ...
Ações de Z2k com o conjunto de pontos fixos conexo e a propriedade CP
(Universidade Federal de São Carlos, 2021-10-27)
It is well known that if $\phi:G \times M^m \rightarrow M^m$ is a smooth action of a compact Lie group on a closed smooth manifold, then its fixed point set $F_{\phi} = \bigcup\limits_{i=0}^{n}F^{i}$ is a disjoint union ...
Correlação entre achados ecocardiográficos de função ventricular esquerda e aptidão aeróbica em indivíduos diabéticos
(Universidade Federal de São Carlos, 2021-12-17)
Background: Type 2 diabetes mellitus is a chronic disease capable of causing micro and macrovascular complications, in addition to abnormalities in cardiac function that directly impact aerobic fitness. Studies show that ...
Controle policromático de luz aplicado à produção de microalgas
(Universidade Federal de São Carlos, 2021-12-08)
Microalgae have drawn the attention of the biotechnology industry for being natural synthesizers of high added value products such as β-carotene, astaxanthin, lutein, docosahexaenoic acid, proteins, and pigments. However, ...
Análise da flambagem de paredes de alvenaria estrutural
(Universidade Federal de São Carlos, 2022-09-01)
This research presents analyzes of slender reinforced masonry walls built with concrete units. The analysis was performed with finite element modeling. The Abaqus computational package was used to develop the models. Slender ...
Estudo da remoção de contaminantes emergentes em estação de tratamento de esgoto equipada com biorreator acoplado a filtração por membrana: uma alternativa para a produção de água de reuso
(Universidade Federal de São Carlos, 2022-03-24)
The degradation of water bodies and the indiscriminate use associated with frequent and intense drought episodes have compromised the availability of water. Thus, the production of reused water from sewage treatment has ...
Extensões H-cleft distinguidas por H-identidades polinomiais
(Universidade Federal de São Carlos, 2022-05-27)
Our main object of study is the well-known question asking whether the set of polynomials identities distinguishes PI-algebras up to isomorphism. Let k be an algebraically closed field of characteristic 0 and H a non-semisimple ...
Vitrocerâmicas de silicato de lítio com gradientes microestruturais - simulações e experimentos
(Universidade Federal de São Carlos, 2022-08-08)
The microstructure of glass-ceramics (GCs) depends on their chemical
composition and thermal history, from the cooling of the precursor glass to the
heat treatments. In glass production, the cooling rate on the surface ...
