2. Optimized microlens-array geometry for Hartmann-Shack wavefront sensor: design, fabrication and test
The Hartmann-Shack (H-S) wavefront sensor is now deployed in many different fields, from astronomy to industrial inspection, where the quality of optical media or components can be measured by the distortions (wavefront aberrations) they impart on a wavefront transmitted or reflected by them. In ophthalmology, this sensor is a core component of major aberrom

3. Linear dimensional change, compressive strength and detail reproduction in type IV dental stone dried at room temperature and in a microwave oven
The type IV dental stone is widely used for the fabrication of dyes and master casts for fixed and removable partial prostheses. It is typically normal to wait at least 24 hours for the casts to dry prior to beginning the laboratory procedures. The waiting time has been shown to be greatly reduced by using microwave drying. OBJECTIVE: This study evaluated th

4. Fabricação e caracterização de sensor de pixel ativo com tecnologia NMOS de porta metalica / Fabrication and characterization of active pixel sensors using metal gate NMOS technology
Active Pixel Sensors (APS) based on a simple nMOS technology with high aspect ratio may present good sensitivity to photodetection and offer a low cost option for image sensing circuits. This work presents the layout, fabrication and characterization of photodiodes, transistors and APSs built at the Center for Semiconductor Components (CCS). All the process

5. Fabricação e caracterização de dispositivos poliméricos emissores de luz com camada ativa de poli(2-metóxi, 5-(2-etil-hexilóxi)-1,4-fenileno vinileno) (MEH-PPV) / Fabrication and characterization of polymer light-emitting diodes with active layer composed by poly(2-methoxy, 5-(2-etil-hexilhoxy)-1,4-phenilene vinilene) (MEH-PPV).
Polymer light emitting diodes (PLEDs) have been widely investigated as candidate materials for display fabrication. The main advantages exhibited by PLEDs are the low-cost processing and possibility of large-area display fabrication, in comparison to the conventional liquid crystal displays (LCDs). Although the engineering aspects concerning device fabricati

6. In vitro sealing ability of white and gray mineral trioxide aggregate (MTA) and white Portland cement used as apical plugs
This study evaluated the sealing ability of apical plugs made of white and gray MTA-Angelus® and white Portland cement placed via the root canal and having different thicknesses (2, 5 and 7 mm). Ninety extracted human single-rooted teeth were instrumented using a size 40 K-file to standardize the foraminal opening by the stepback technique. The teeth were a

7. Sensores eletroquímicos: considerações sobre mecanismos de funcionamento e aplicações no monitoramento de espécies químicas em ambientes microscópicos
Electrochemical sensors have attracted considerable attention in recent years because they provide data about the chemical state of our surroundings and the dynamics of the chemical transformations in the form a spatially resolved image. Particular interest has been directed to measurements in restricted-volume samples as new technologies enable the fabricat

8. The making of the pop idol: a textual analysis of video clips and building the image of Madonna. / A fabricação do ídolo pop: a análise textual de videoclipes e a construção da imagem de Madonna.
Madonnas videography, begun over 20 years ago, follows the evolution of music video itself, also consolidated in the 1980s. Ever since, Madonnas continuous popularity has provided her and her supporting team with a basis to perform both stylistic and thematic innovations in her music videos. The singer adopted music videos as an additional unfolding to her w

9. Fabricação de multicamadas de Quantum Dots de PbTe por laser ablation
This thesis was dedicated to the fabrication of thin films, quantum dots and multilayer ofIV-VI semi conducting materiaIs by pulsed-Iaser deposition (PLD). In the first part we report on the construction of a "home made" facility for pulsed laser deposition. The basic experimental set-up fabricated for PLD consists of a vacuum chamber pumped to a base pressu

12. Imaging and manipulation of high-density lipoproteins.
The atomic force microscope (AFM) has been used to image a variety of biological systems, but has rarely been applied to soluble protein-lipid complexes. One of the primary physiological protein-lipid complexes is the high-density lipoproteins (HDL), responsible for the transport of cholesterol from the peripheral tissues and other lipoproteins to the liver.
