Avaliação de procedimentos de extração e determinação de boro em amostras de solo e plantas
(Universidade Federal de São Carlos, 2006-02-20)
Boron is
present in soils as an essential nutrient for plants growing. Soils and plants sample
preparation procedures were evaluated aiming to compare the extractors efficiency.
Sample preparation methods, such as dry ...
Contribuições para o aprimoramento na utilização de andaimes suspensos em construções de edifícios conforme diretrizes da NR- 18
(Universidade Federal de São Carlos, 2006-12-13)
In this dissertation the subject of labor safety and health is approached, focusing on prevention of accidents when working in suspended scaffold, based on NR-18 as a preventive tool. The study initially presents information ...
Propriedades eletrônicas e espectroscópicas de aglomerados de moléculas interestelares
(Universidade Federal de São Carlos, 2013-08-29)
The interstellar médium (ISM) is a gigantic reservoir of atoms and molecules of different shapes and sizes. In general, they are concentrated in enormously big regions in space known as interstellar cloud. There exist huge ...
Estudo da eletrodeposição da liga Fe-Mo a partir de soluções levemente alcalinas contendo NTA - Nitrilo Acetato de Sódio
(Universidade Federal de São Carlos, 2012-02-29)
Fe-Mo alloys were electrochemically deposited on to a Pt substrate, from an alkaline solution containing FeCl3, Na2MoO4, trisodium nitrilotriacetic (NTA), in which Fe3+ ions were ddissolved to form [Fe(OH)(NTA)]-, ...
Indicadores de desempenho como instrumento de gestão de lodo de estações de tratamento de esgoto
(Universidade Federal de São Carlos, 2023-04-27)
The improvement and efficiency of sanitary sewage systems depend on management from an integrated perspective. An important stage that composes the sewage systems is the management of the solid waste generated, however, ...
Platforms based on semiconductors for application in quantum computing
(Universidade Federal de São Carlos, 2023-06-02)
This thesis is composed of three parts. In the first part, a study of transport in semiconductor nanowires is carried out, in which the multichannel scattering occurs in a certain finite region, providing a reentrance in ...
Métodos Bayesianos para seleção de modelos de mistura de distribuições normais e t de Student assimétricas
(Universidade Federal de São Carlos, 2023-06-28)
In this work, we consider mixture models whose components of the mixture are modeled by the skew normal and skew t distributions. For the estimation of these skew mixtures models, we used a Bayesian approach, via Markov ...
Eletrodeposição de filmes do tipo Ni-X (X=P, Cu ou Cu-P) a partir de banhos contendo aspartato
(Universidade Federal de São Carlos, 2022-11-25)
In the present work, aspects related to the electrodeposition of Ni-based metal films - either pure metal or Ni-P, Ni-Cu, and Ni-Cu-P alloys - from baths containing aspartate complexes as electroactive species and hypophosphite ...
Avaliação de aditivos poliméricos e cerâmicos para a otimização microestrutural de refratários semi-isolantes
(Universidade Federal de São Carlos, 2023-07-21)
Macroporous insulating refractories have been extensively investigated due to their low thermal conductivity, low density, and non-toxicity compared to fibrous ceramic insulators. However, there are still challenges in ...
Sistematização da inspeção de código SQL utilizando a técnica stepwise abstraction e a ferramenta CRISTA
(Universidade Federal de São Carlos, 2015-03-16)
Context: Inspections are a software quality assurance activity which can be applied throughout the development process and in different types of artifacts, since it is a statistic activity, based essentially on reading ...
