Symmetric and non-symmetric Jack Functions
(Universidade Federal de São Carlos, 2020-05-29)
The goal of this dissertation is to present the theory of Jack functions from the standpoint of algebraic combinatorics. The presentation of symmetric functions is largely centred on the first chapter of MacDonald's ...
Modificação de filtros de ar condicionado com nanopartículas de cobre com efeito biocida para ambientes indoor rooms
(Universidade Federal de São Carlos, 2020-08-07)
Filter media, as used in air conditioning system, are the first physic barrier between external environment and indoor rooms. To avoid the contamination in indoor rooms, one preventive measure is to contain the proliferation ...
Development of a stable diode laser system for cavity-assisted matter-wave interferometry
(Universidade Federal de São Carlos, 2020-08-27)
The project is part of an experiment that has been developed to probe the dynamics of ultracold strontium atoms in a vertical one-dimensional optical lattice sustained by a ring cavity. A fundamental part of the experiment ...
Estudo sistemático da condutividade iônica de vitrocerâmicas NASICON: influência de tratamentos isotérmicos e novas substituições iônicas
(Universidade Federal de São Carlos, 2020-09-24)
The synthesis of solid electrolytes and the optimization of their ionic conductivity are topics of scientific interest since these components are essential for the current density and the half-life of the sodium batteries. ...
Previsão de viscosidade e temperatura liquidus de vidros óxidos via redes neurais artificiais
(Universidade Federal de São Carlos, 2020-04-30)
The number of glass compositions that have already been studied (~10^5) is many times smaller than the potential glass compositions (~10^52). The traditional method “cook and look” all of the potential compositions to ...
Avaliação de matérias-primas alternativas com ação ligante ou sinterizante para concretos refratários
(Universidade Federal de São Carlos, 2020-08-05)
Refractory materials are used as linings in most equipment of heavy industries. As the latter are continuously seeking to reduce expenses in order to increase their energy efficiency and productivity, the evaluation of ...
Transesterificação de ésteres etílicos e estudo cinético usando a sílica CTA-MCM-41
(Universidade Federal de São Carlos, 2020-02-28)
The synthesis of biodiesel, through transesterification, occurs industrially in the presence of basic homogeneous catalysts, where others steps are necessary, such as washing and neutralization of the final product due to ...
Complexos semi-sanduíche de RuII/areno e produtos naturais: uma promissora combinação para novos metalofármacos
(Universidade Federal de São Carlos, 2020-10-15)
This thesis presents the synthesis, characterization and evaluation of antitumor activity of nineteen neutral and monocatonic organometallic complexes containing ligands derived from natural products. The complexes were ...
Abordagem investigativa como fator de motivação em três cursos da área de Química de uma instituição pública do Estado de São Paulo
(Universidade Federal de São Carlos, 2020-08-07)
Laboratory classes have great potential to motivate students in science courses, whether to learn new knowledge or to demonstrate what they have already learnt. There are some ways of working in the laboratory and two draw ...
Química experimental: uma abordagem investigativa do teor de ferro em alimentos por espectrofotometria
(Universidade Federal de São Carlos, 2020-05-25)
Practical activities in the laboratory are guided by script with traditional procedures, and in order to carry out the experiments, it is necessary to follow a linear sequence, which the professor or text direct what and ...
