1. MODELAGEM NUMÉRICA DE FLUXO 3D EM MEIOS POROSOS / NUMERICAL MODELING OF 3D FLOW IN POROUS MEDIA
Numerical simulations tend to simplify the behavior of real problems, mainly through the choice of 2D models to describe the hydromechanical responses of earth dams, excavations, foundations, etc., partly because it is easier to construct geometrical meshes, it is simpler to impose the required boundary conditions, the computer calculations are done more rap

2. DETERMINAÇÃO DAS CARACTERÍSTICAS TRANSIENTES DE UM MEDIDOR DE PH: QUALIFICAÇÃO METROLÓGICA / DETERMINATION OF THE TRANSIENT CHARACTERISTICS OF A PH ELECTROCHEMICAL ANALYSER: METROLOGICAL QUALIFICATION
Os medidores de pH existentes no mercado indicam valores confiáveis, dentro de uma incerteza declarada para cada modelo fabricado. Entretanto, normalmente, não é citada a especificação em termos do tempo necessário para alcançar estes valores, devido ao tempo de resposta do instrumento. Esta dissertação de mestrado tem como objetivo desenvolver uma

3. The Angiosperm Gibberellin-GID1-DELLA Growth Regulatory Mechanism: How an “Inhibitor of an Inhibitor” Enables Flexible Response to Fluctuating Environments
The phytohormone gibberellin (GA) has long been known to regulate the growth, development, and life cycle progression of flowering plants. However, the molecular GA-GID1-DELLA mechanism that enables plants to respond to GA has only recently been discovered. In addition, studies published in the last few years have highlighted previously unsuspected roles for

4. Transient magnetic effects in a scale model of the earth's core
Scale model experiments are described in which the contribution to the dipole magnetic field of a conducting sphere (simulating the earth's core) by initially closed, internal flux loops is measured. A magnetic loop is maintained by constant current in a toroidal coil, in a mercury sphere. The circuit is then opened, which allows the magnetic loop to diffuse
