This research investigated the modeling and development of a magnetically levitated vertical axis wind turbine (LVAWT). The goal of the research was to generate power using LVAWT, which was achieved by harnessing repulsive forces within permanent magnets, the wind turbine's vertically oriented vanes can be levitated, to minimize frictional losses by eliminating contact between the shaft and frictionless bearings. The Computer Aided Design (CAD) model was achieved and simulated. The turbine assembly maintains optimal blade rotation. The shaft, connected through its normal axes, links to the alternator via a direct drive connection between the generator and turbine shafts. Stationary guide vanes (chutes) were incorporated into the prototype......

This article discusses the use of intellectual property (IP) in the curricular institutions of Political Projects (PPC) of higher engineering courses, as well as its influences on the production of IP in important educational institutions. For such an analysis to be possible, an exploratory research was needed on the educational institutions that most deposited IP, specifically patents, in Brazil, in which institutions that stood out at the national level were UFCG, UFPB, UFMG, UNESP, UFPE and UNICAMP In which, with the objective of a counterpoint of view, they were listed as educational institutions that produced the most IP in the state of Rondônia, a state which occupies the 24th position in the creation of patent production in Brazil, and, as chosen by the UNIR and IFRO. Thus, there is a dizzying relationship between the institutions that work with IP within the curriculum and their patent productions.

This study aims to conduct a comparative analysis between conventional microfiltration and tangential filtration applied to produced water treatment from the Fazenda Bálsamo field located in Esplanada, Bahia, Brazil. Produced water is the effluent resulting from primary oil processing. Its disposal poses a significant challenge for oil companies due to the large volumes generated during oil production. An appropriate alternative for its final disposal is reinjection into oil wells after treatment to meet the required process standards. To facilitate this purpose, the water must undergo treatments to prevent damage to production facilities and the environment. Filtration involves the retention of suspended solids in a particular fluid through a filtering medium. Consequently, two vacuum filtration systems were developed........

Growing grapes as a hobby and for the production of home-made alcohol on a small scale is deeply rooted in the everyday life and folk psychology of Bulgarians. Since time immemorial, alcoholic beverages - wine and rakia (Bulgarian strong brandy) - have been consumed in the evening (and not only). There is an expression for part of the day - "on rakia time". The areas with vineyards are on different scales - large areas for industrial production and small family vineyards. There is no data on the time of picking the small family plots. The duration of harvesting the grapes from a 1.2 da vineyard by 6 pickers is one calendar day.

The potential of using ANN for predicting the mechanical properties of natural fiber for wind turbine blade application has been studied and reported in the present work. Experimental data from reported research on the studies of a variety of natural fibers was collected and stored in the MySQL database. This database was split into training and testing sets and was subsequently used in the development of the predictive model. Back-propagation neural network was developed to predict mechanical properties of fiber and was found to be capable of prediction with an overall regression of 0.98717, which indicated that ANN can be attractive as mechanical properties of fiber predictor.

Background: Photovoltaic research continues to focus on organic-inorganic hybrid perovskites, ten years after they were originally mentioned in a report on the deployment of solar cells. Appropriate material selection for various layers has allowed for high power conversion efficiency (PCE) values, which currently exceed 24 percent. Unfortunately, poisonous lead is included in metal halide perovskite solar cells (PSCs), which poses a significant risk to their commercialization. scientific into lead-free metal halide perovskite is being conducted extensively by the PSC scientific community in an effort to address lead toxicity concerns in perovskite-based solar cells. A unique configuration for solar cells is proposed in this study, consisting of FTO, Transition Metal Di-Chalcogenides, Perovskite, Copper Thiocyanate.......

This paper discusses the importance of adapting conventional photometric quantities when lighting systems with low luminosity levels are under analysis. In this way, this work presents an alternative methodology that can be applied to lighting projects in outdoor lighting which typically operate under mesopic conditions. The CIE technical report 191:2010 proposes correction factors that convert conventional photometric quantities (photopic) into adapted ones aiming a better correspondence with mesopic conditions. A required parameter for obtaining these correction factors is the relationship between the scotopic and photopic luminous fluxes of the light source employed (S/P ratio), whose determination requires special equipment that is not easily available. Thus, this paper proposes......
