1. Physical Vapor Deposited Films of a Perylene Derivative: Supramolecular Arrangement and Thermal Stability
The analysis of supramolecular arrangement is essential to understand the role of this key factor on the optical and electrical properties of organic thin films. In this work, thin solid films of bis(phenethylimido) perylene (PhPTCD) fabricated using physical vapor deposition (PVD) technique (thermal evaporation), deposited simultaneously onto different subs

2. Caracterización de semielaborados de aleaciones de titanio procesadas por extrusión y laminación perforación (proceso Mannesmann)
ABSTRACTFor the manufacture of seamless pipes and tubes are used, as raw materials, hollow bars from hot deformation processes like extrusion and rotary tube piercing (Mannesmann process). Starting from these semi-elaborated products and by means of successive cross sections reductions through tube drawing or tube rolling (cold pilgering) the requested final

3. Estudo da influência de macro-rugosidades do leito de um canal hidráulico sobre o coeficiente de reoxigenação superficial / Study about the influence of macro-roughness in a bed of a hydraulic channel on the reoxygenation superficial coefficient
O parâmetro que determina o processo de transferência de oxigênio através da interface ar-água em escoamentos com superficie livre é o coeficiente de reaeração superficial, K IND.2. Existe um grande número de equações na literatura científica que realizam a previsão do coeficiente de reaeração, no entanto, a maioria dessas equações considera

4. Discriminacao de lateritas mineralizadas em ferro no deposito de N1 (Carajas-PA) por radar imageador: uma avaliacao atraves de classificacao textural / Discrimination of iron ore laterites in the deposit N1 (Crajas - PA) using radar imagery: an evaluation through textural classification
The use of imaging SAR presents a high potencial for geological applications in cloudy cover regions, such as the Brazilian Amazon, due to the side viewing geometry and the longer wavelengths, which result in the enhancement of the terrain and the all-weather sensing capability. As the macro and micro topography are normally highlighted in the Syntetic Apert
