In Amazonas, most of the municipalities are not connected to the National Interconnected System (SIN), and it is necessary to hire Independent Energy Producers (PIE) to meet local demand. In these municipalities, diesel thermoelectric plants are usually presented as the most viable option for energy generation. This fuel was used in the generation of electricity in Coari until 2020, when Siemens started operating a gas-fired thermoelectric plant in the city. The main objective of this work is to analyze the operating conditions of the new plant and the results achieved. As an introduction, the energy sector in the country and in the state of Amazonas was addressed, as a way of contextualizing and justifying the relevance of the theme. There was also a brief presentation of the installed plant, raising hypotheses and questions about it. Data regarding the supply contract and average fuel price were obtained through agencies and public companies in the sector, such as ANEEL and EPE. After the presentation of the theoretical framework, technical data disclosed by the turbine manufacturer (Siemens) was collected. The simulation software RETScreen, developed by the Government of Canada, made it possible to carry out the analyses. The results showed that the project is economically profitable for the company contracted to supply the energy and that the electricity generated in the gas plant with combined cycle costs 73% less than the energy produced in the diesel plants. The maximum power achieved by the plant was 38,891 kWh and the combined cycle efficiency was calculated at 49.63%. Finally, comparisons were made between the performance of the plant in simple and combined cycles, showing the relevance of the heat recovery system.

Elevators are an essential equipment for the operation of almost all developments, such as large commercial and residential buildings, hotels, malls and hospitals. In cases where elevators do not work properly or stop frequently, the success of this ploy can be seriously compromised due to users' fear of getting stuck in the equipment. The present work show the guidelines for the construction of the elevator boxes to minimize or exclude mistakes in the construction stage, which end up harming and even unfeasible the services of installation, bringing expenses and inconvenience for who was hired (works) as well as for the Contractors (manufacturers of lifts). These guidelines will provide for those responsible for the execution of the boxes the information needed to understand the process and procedures to avoid the construction problems that are primarily responsible for the problems faced by the assembly that end up impacting the final delivery of the lift. The data were obtained through surveys, interviews and observation in Manaus works in the most different stages, both pre-installation, assembly and technical assistance. In this way it was possible to confirm the difficulties encountered and how the pre-install the processes impact on the assembly services and the final delivery of the equipment. It has been realized by an orientation of the whole process in the integration and follow-up through a detailed schedule of activities by the contractor and the contractor can minimize many problems and unnecessary expenses of time and money in this process for both involved.

The high productivity of an industrial production line is the desire of all large, medium and small companies. Because if the line operates at its maximum performance, it will deliver a larger quantity of products to the market, within all its quality specifications, lower costs, generating the profit expected by the factory. But, over the years, the equipment on the production line deteriorates, until it reaches a point where it is not possible to deliver the expected demand. With that, this work will present a methodology that seeks to restore the performance of this production line, seeking to identify the problem, treat root causes, solve anomalies, aiming to leave the production line with a high efficiency, minimizing production costs, improving the work environment for the operator, generating profit for the company and meeting consumer needs with quality. Then, from this project, it was possible to elaborate the standard, describing the step-by-step to be followed, so that the proposed objective is achieved, which is to improve the availability of a production line. Where this standard was applied and its efficiency of analysis and problem solving was verified.

Amazonas is the largest state in Brazil, with dense forests and large voluminous rivers, the 62 municipalities spread over its lands suffer from this Amazonian cost, which are major logistical and investment problems due to the large territorial area of the region. Serving this population with basic resources and electricity is challenging, as it makes the National Interconnected System (SIN) unfeasible to cross the Amazon and serve these municipalities. The state has several isolated and thermoelectric systems to serve the communities, even though the region has the largest water resources in the country for hydroelectric generation, and it is in the Amazon Forest that the largest quantity of diesel and natural gas thermoelectric plants is concentrated, damaging the sustainability of the region with the absence of renewable resources. This work will analyze the data of the micro-region of the Madeira River located in the state of Amazonas and the possibility of installing Small Hydroelectric Power Plants (SHPP) with Bulb type hydraulic turbines to serve those municipalities. The adopted methodology is characterized as bibliographic research, of a descriptive character and analyzing data provided by the national energy regulatory agencies, seeking to meet the population's energy demand in a sustainable manner. In this way, it was analyzed which regions would benefit, the demand that would need to be met for those municipalities and the positive gain that can be obtained using the technology of bulb type SHPPs, leaving aside non-renewable models or that cause great environmental impact such as the large Hydroelectric Power Plants (HEP) that are being built. The results show that there is a possibility of implantation of large HEP, however in the research for more sustainable conditions and of less impact for the region, the use of bulb turbines in SHPP becomes more viable and with less impacts.

This research intends to portray the operation of Radar Star2000 in the detection of aircraft for air traffic control in Manaus. It is understood that air traffic is characterized by the circulation of several aircraft and requires the provision of services by controllers who monitor, guide and give all guidelines so that the flow is safe, fast and orderly, both in the air and on the ground. In addition to the human contribution, this work would not be possible if certain elements were not made up such as equipment and “software”, being extremely necessary to have greater ease in controlling aircraft in order to always maintain the highest levels of safety. It is noteworthy that the Radar, being a device that allows detecting objects and infers distances from electromagnetic waves emitted by the equipment itself and received by the aircraft's echo, helps to maintain the safety of air traffic, which is essential for a quantitative greater number of aircraft that land and take off at all times, transporting cargo, people, etc. In this sense, this study was carried out with a qualitative approach, where bibliographical and documentary research were carried out, emphasizing the verification of the composition and functioning of the Radar Star2000 through technical manuals, as well as the "software" that assists the aforementioned equipment in the detection of aircraft for traffic control. What was obtained as a result was the finding that the Radar generated a positive impact on the fluidity of the aircraft, since the city of Manaus has the second largest cargo airport in Brazil - Eduardo Gomes International Airport -, being the largest in the North Region In addition to the fact that the use of the equipment has contributed to the safety of people who use the aircraft for different purposes, it also helps the economy of the State.

Ventilation installation and air-conditioning systems in public and collective places are highly important to guarantee simultaneously the parameters control that determine the thermal comfort of the occupants. In addition to ensuring the thermal comfort, the perfect functioning of this type of system will provide levels of air quality and purity within acceptable standarts, eliminating or minimizing the spread of deseases that might affect the human health. In Brazil there are norms and laws that define the installation criteria for air-conditioning systems. In this work, a study was carried out based on the current Brazilian standards that rule the installation of these systems, to evaluate whether the normative requirements were met in order to ensure the appropriate parameters of thermal comfort and air quality. Thus, this research aims to evaluate whether the installation of a ventilation and air conditioning system in a control room of an oil refinery presents the expected performance for which it was designed.

In our schools, the teaching of physics consists of passing on a pile of information without connection with the world that surrounds the student. Forgetting that Physics is a science that studies natural phenomena, through observation. In view of the above, the present work aims to develop a sequence of activities on free fall using the Hackeduca Conecta application, with experiments simulated by the same application, for students of the 1st grade of High School, following the pedagogical theory of Jerome Bruner that deals with “Discovery teaching”. The proposal consists of analyzing the movement of the bodies through the "Free Fall" where data will be programmed and collected through sensors and transmitted to the computer using Arduino, so we will be able to generate graphs to analyze the movement of the bodies, discuss values and assist students in solving problems through tests, analyze some important parameters in this phenomenon studied and also measure the value of gravity acceleration. It is hoped that this Teaching-Learning proposal will make student learning effective and very profitable in order to make the student an investigator and a critical-reflective thinker and that all this knowledge acquired by him be profitable in his reality.

In this monograph the development of a prototype of a cargo elevator is presented. The theme is in the area of elevators / automation, considering the technological advances in the part of drives, control, signaling and power. The objective of this work is the construction of a prototype of load elevator for didactic purposes using an embedded circuit board to execute the logical part of programming of the movement of rise and decide of the elevator when requested in the respective floors. For the accomplishment of the work, a methodology of applied research nature was adopted, according to Cervo, Bervian and Silva (2007). Initially there was a discussion about Electric Elevators, having as subsidy Brazilian technical norms and bibliographies. Blum Jeremy, 2016, explicitly explains the method of programming an arduino in a very basic way to more complex projects, Dal Monte, 2000, led us to think as in the beginnings of the creation of the first designs of lifting machines developed by the Egyptians to the most modern already developed by men and NBR 5666 guided us in the norms that govern passenger lifts in Brazil, all these works, corroborated in the idealization and creation of the prototype. The proposal of modeling a load elevator, using a low cost embedded system, was carried out in its entirety through experimental tests as well as facilitated the understanding of the operation, handling and application.
