This Paper present the steps to build an hydrogen cell emphasizing the need to use as a renewable energy source, being applied with internal combustion engines, as an efficient result obtained through electrolysis. Data presented in tables and graphs were collected and analyzed, both for urban streets and for highways. The tests in urban streets the vehicle presented 15.5 kilometers per liter of fuel (km/l), with efficiency of 38% compared to ordinary fuel, as well as on highways, made 18.9 km/l, with 33%, respectively acting at 60.5 kilometers per hour (km/h), the gain is due the fact that the system, which is directly linked to the generator currents and voltages consumption, implying that the higher current consumption, greater will be the gas generation. The results of the project show the veracity of achieving economy, yield and efficiency through hydrogen, allowing the possibility of implementation not only in vehicles but, in all varieties of engines available on the market today, and the substitution for other sources.

This article presents the construction of a prototype of internet of things application to monitoring and remote control of a resin drying oven to electric restored engines, using the internet as the main means of data transfer and a free server, the complete system consists of a special board to get the temperature data from the drying oven, a liquid crystal display, a data viewing environment to provides the data access and the control from any device inside of local network and the central microcontroller ESP8266 with native Wireless Fidelity (Wi-Fi), firmware upgrades can be downloaded through Internet Protocol (IP) address without the need of traditional communication cables, the system was developed do get in the industry 4.0, applying a lightweight protocol, the internet to data transmission, and a low cost microcontroller.

This paper aims to analyze through field research the effects of brazilian regulations , where the main focus is on accidents related to work with electricity (NR-10), although NR-10 is a mandatory regulation in Brazil, not all companies are using them as internal control rules, especially those in which external oversight is not as effective, thus comparing one large-sized company with a medium-sized company, the data collected were able to express the main concern of these companies regarding the safety of their employees and the imminence of fines and legal proceedings.

This article evaluates the maintenance management of electrical equipment of medical-hospital units in a Neonatal Intensive Care Unit (ICU), with the objective of analyzing the importance and performance of services in the area of medical equipment maintenance, during its implementation in a private hospital in the city of Manaus, Amazonas. In addition it seeks to plan the actions and the systematization, identifying the methodologies that will be applied, to suit the sector. In this context, to demonstrate, especially in the area of maintenance plan management, the importance of an engineering professional in the maintenance management of medical electrical equipments, relating engineering to health.
