Alguns aspectos químicos envolvidos na interação Hypsipyla grandella (broca-do-mogno e Swietenia macrophylla (Mogno)
(Universidade Federal de São Carlos, 2002-11-08)
The interaction between Hypsipyla grandella (Mahogany bore) and Swietenia macrophylla was studied in order to understand the chemical and ecological aspects involved on this process. H. grandella is a shoot borer lepdoptera ...
Propriedades estáticas e dinâmicas de portadores em heteroestruturas semicondutoras.
(Universidade Federal de São Carlos, 2002-10-30)
We have studied the dynamic and the stationary properties of carriers in semiconductor
heterostructures submitted to electric fields AC and DC and to magnetic fields
within the effective-mass approximation based on ...
Estudos microgravimétricos da deposição de cobre sobre eletrodos de cromo passivado.
(Universidade Federal de São Carlos, 2002-11-29)
Recently were obtained in our laboratory results indicating that Cu deposition on
Cr2O3 happens in two steps: at the first one, there is the deposition of an amount
smaller than one Cu monolayer, and at the second one there ...
Peso de Drude em anéis unidimensionais com potenciais de substituição e atravessados por fluxo magnético
(Universidade Federal de São Carlos, 2002-04-11)
In the present work the Drude weight is calculated to study the capacity of conduction at finite temperatures in one-dimensional rings with the potencial given by the sequences of different degrees of randomness and threaded ...
Seções de choque diferenciais absolutas para o espalhamento elástico de elétrons de energias baixas e intermediárias por moléculas poliatômicas em fase gasosa
(Universidade Federal de São Carlos, 2002-05-27)
In this work we report absolute elastic differential cross sections (DCS) measurements for electron collisions with OCS, CO2, CH4, NO, N2O, CHF3 e C2F6 molecules in gas phase. The measurements cover the angular range from ...
Ansatz de Bethe para cadeias quânticas de spin-1 com condições de contorno
(Universidade Federal de São Carlos, 2002-03-21)
The procedure for obtaining integrable open spin chain Hamiltonians via reflection
matrices explicitly carried out for some three-state vertex models. We have considered
the 19-vertex models of Zamolodchikov-Fateev and ...
Investigação da formação da fase óxido e estudo da influência da microestrutura e morfologia nas propriedades eletrocrômicas de filmes finos de Nb2O5.
(Universidade Federal de São Carlos, 2002-08-30)
Nb2O5 is known by your capacity of optical absorption variation, which it happens due
to reduction and small ions intercalation, such as Li+, double process. In this work, Nb2O5 electrochromic films were produced by Pechini ...
Implementação dos serviços de comunicação e monitoração em um ambiente para desenvolvimento de sistemas distribuídos.
(Universidade Federal de São Carlos, 2002-08-30)
The TEV (Teaching Environment for Virtuoso) environment is a set of teaching tools that support the phases of analysis, design, implementation, depuration and test of real-time applications which are executed using ...
Estudo da influência de baixos teores de platina em catalisadores Ni/γ-Al2O3 nos processos de reforma a vapor, oxidação parcial e reforma oxidativa do metano.
(Universidade Federal de São Carlos, 2002-08-22)
The effect of platinum addition in low contents (0.1 and 0.3 % wt.) in nickel supported γ−alumina catalyst (15% Ni wt.) has been investigated. The samples were prepared by successive wet impregnations of metal ions over ...
Transformação de dataflex procedural para visual dataflex orientado a objetos reusando um framework.
(Universidade Federal de São Carlos, 2002-02-22)
This work presents a strategy for transformation of legacies systems write in Procedural DataFlex (DFP), for systems in Objects Oriented Visual DataFlex (VDFOO) reusing a Framework, denominated DataFlex Application Framework ...
