Introdução aos sistemas aviônicos de rádio navegação

This work is focused on the subject of air radio navigation systems embedded on aircraft and in the ground stations. Initially is presented a historical context and motivation of the chosen theme. In the following chapters the basics avionics systems are presented, ADF, VOR, DME and ILS such that there is a deepening of electronics theory behind the operation of each system. In this graduate work were presented theories involved in systems such as the definition and creation of radio waves, the frequency spectrum used by each system, the modulation and demodulation of waves, the operating block diagrams of embedded receiver in the aircraft and the terrestrial source station, and the errors involved in the use of each system

Utilização de painéis solares fotovoltaicos no segmento residencial

In order to diversify the global and national energy matrix and reduce harmful impacts on the environment caused by the emission of polluting gases into the atmosphere, the use of clean and renewable energy sources is presented as a good alternative. This work discusses the use of photovoltaic solar energy, a source that presents such characteristics. The photovoltaic system under study is the type distributed connected to the grid, in the residential segment. It is informed of its use in the global and national levels. They are also present their characteristics, electrical and electronic circuits that make up the equipment required for its operation and the design of a system to be installed in a residence

Sensibilização comportamental ao etanol e neuroadaptações envolvendo a proteína (DELTA)FOSB: efeitos do tratamento com N-Acetilcisteína em camundongos

Pharmacological treatments currently used in ethanol addiction are inefficient, requiring new drugs for this purpose. The pro-drug N-Acetylcysteine (N-Ac) has shown efficacy in the treatment of addiction to cocaine and nicotine in preclinical research and clinical pilot studies. When administered, N-Ac is subsequently converted to cysteine, and cystine, which has an action on the central nervous system. However, there are few data about the possible application of N-Ac in the ethanol addiction. Behavioral sensitization is the gradual increase of the psychostimulant effects induced by repeated administration of drugs of abuse, including ethanol, and its development has been linked to important neuroadaptations in addiction. These neuroadaptations occur in neural circuits that mediate the reinforcing properties of these drugs and may involve several proteins. The ΔFosB protein accumulates in neurons after repeated activation and mediates long lasting changes in response to drugs of abuse. These changes are manifested mainly in the nucleus accumbens (Acb) and prefrontal cortex (PFC) neurons. The aim of the study was to evaluate the effects of N-Ac treatment in the development of ethanol behavioral sensitization and in alterations in the ΔFosB protein in mice. Swiss male mice were exposed to a standardized behavioral sensitization protocol to the experimental conditions of the laboratory and treated with N-Ac. At the end of behavioral sensitization procedure, animals were euthanized and their brains removed for ΔFosB quantification by Western blotting. Two experiments of behavioral sensitization were performed to the standardization of the protocol. The first, although effective in demonstrating the development of behavioral sensitization, was not effective in allowing the evaluation of the expression of the behavioral sensitization. The age of the animals and the conditions of luminosity and color of locomotion apparatus were changed and a new...

Pesquisa, projeto e construção de um sistema de ignição sem distribuidor

This work intends to know the most types of ignition systems, studying its history, the way it works, applications and some examples. The assembly of a distributor less ignition system is also required. All vehicles powered by internal combustion engines need an ignition system that allows this engine to ignite the air-fuel mixture using its ignition system in the best possible manner. The main goal of an ignition system is to obtain a spark having enough energy to start the chemical reaction of the oxygen and the fuel. It took a study dealing with the various types of ignition systems since their creation at the beginning of the last century until 2015. The work starts studying the high tension magneto ignition system and later together with the low tension ignition system, going on with the conventional ignition system and finally accomplishing with the various types of electronic ignition systems. It was studied and implemented an electronic circuit to power a double spark ignition system also known as wasted spark ignition system. This circuit was assembled with an electric pulse generator and powered mechanically by a dc electric motor of the variable rpm type
