Research Projects
NATURAL SCIENCES AND THEIR TECHNOLOGIES:
In this project, we propose the restructuring of the Laboratory for Research and Development in Exact Sciences Teaching (LAPECE), which will support PPGEF in remote and possibly hybrid teaching activities in postgraduate studies. LAPECE will also be able to support undergraduate and continuing education courses for basic education teachers, promoted by UFRJ-Macaé. We also intend to stimulate research and development of educational products through the adaptation of LAPECE and also through interaction with renowned researchers in the area of teaching, through panels, short courses and conferences (remote or not). It is worth noting that any in-person activities will only be carried out if permitted by the health authorities. We hope to consolidate the PPGEF/MNPEF at UFRJ-Macaé as a reference in the training of physics and science teachers in basic education, indirectly contributing to the training of basic education students, reducing school dropouts and improving the IDEB in the municipalities where we operate.

Dark matter and dark energy form the most formidable problem in Physics and Cosmology at the beginning of this century. General Relativity has proven to be the most appropriate theory for describing gravitational phenomena on an astrophysical scale. It is successfully applied to a wide range of situations, from the description of isolated stars, at typical distances from the solar system, to Cosmology, which deals with the greatest possible distances to be observed. However, apparently General Relativity with 'standard' fields has not been appropriate for describing the dark part of the Universe. Here, we seek to understand issues involving Einstein's Theory of Gravitation and interaction with matter fields that can describe dark matter and dark energy, as well as applications of this and field theories in cosmological contexts.
Professor: SANDRO MARCIO RODRIGUES MICHELETTI
The discovery of accelerated expansion in the Universe brought significant challenges to modern cosmology. Questions arose about the validity of the General Theory of Relativity in describing cosmological dynamics and also about the material composition of the Universe. The standard cosmological model, known as LCDM, has proven to be the most compatible with observational data to date. However, there are gaps regarding the nature of the cosmological constant, which is considered a candidate for the dark energy component responsible for the accelerated expansion.
Given this scenario, several alternative models to LCDM have been proposed. The objective of this project is to analyze these models using the Bayesian statistics approach, in order to determine which one is the most likely when considering data from supernovae, baryon acoustic oscillations, spectrum of the cosmic microwave background and information on cosmic expansion obtained from luminous red galaxies.
This project uses data obtained from satellites that are part of international scientific collaborations. Furthermore, it uses computer programming and the Monte Carlo method to perform statistical analyses. Through these techniques, we seek to obtain a more accurate and robust understanding of alternative models in light of available observational evidence.

CIVIL ENGINEERING:
Food production, reconciling food and environmental security, is one of humanity's main challenges today. Conventional agriculture has directly contributed to rising global temperatures, at the same time that the effects of this warming, such as longer and more frequent periods of drought and drought, and greater variability and increase in temperatures, are already impacting productivity and food security , in different regions of the planet. Agrobiodiversity management, genotype-environment interaction and the use of renewable energy can mitigate the effects in scenarios of global climate change and rapid modification of the landscape due to human action. In the state of Rio de Janeiro (ERJ), agricultural production is characterized by small and medium-sized rural properties, using family labor. Among crops, common beans are relevant in the context of the macro challenges faced, as farmers in Rio de Janeiro maintain a large and important agrobiodiversity, which has been studied by UENF. An analysis of the geographic distribution of common bean varieties, in four mesoregions of ERJ studied, identified a strong influence of climatic and cultural factors. The extreme northwest was indicated as a diversity hotspot, however, in three regions, an intense process of genetic erosion was observed. Focal studies in specific experimental plots together with high-throughput and precision envirotyping platforms, which integrate genotypic, phenotypic and environmental information, are being used to enable high-efficiency sustainable agricultural production based on deciphered environmental impacts. This proposal brings together an interinstitutional and multidisciplinary team, and its main objectives are to introduce the envirotyping approach, building an integrated and open platform of phenotypic, genotypic and environmental data for bean crops in ERJ, in order to support conservation and use of the agrobiodiversity found for the crop, and ratify the municipalities of Porciúncula and Varre-Sai, located in the northwest of the state, as bean agrobiodiversity hotspots.

The Irrigasol project consists of a smart irrigation concept that aims to save water and energy use by estimating the plant's water needs and the use of solar energy. The project is inspired by the NEXUS concept proposed by the Food and Agriculture Organization of the United Nations (FAO), which addresses the balance of the Water-Energy-Food tripod, as well as being aligned with SDGs 2, 6 and 7. The Irrigasol can be understood as a social technology, which represents good agricultural production practices, simultaneously addressing water conservation, the rational use of energy, the use of renewable energy and food production (food security), including socioeconomic development. of the small producer.Professor: RAFAEL MALHEIRO DA SILVA DO AMARAL FERREIRA
The WC&WC project began with a pilot sewage treatment plant and is being implemented on the UFRJ-Macaé campus. The station aims to treat sewage generated by a bathroom through vertical flow wetlands. Due to its design, the project can be replicated to other locations that do not have sewage treatment, especially after validating its operation at the pilot station. The project design converges with the proposal of SDG 6: drinking water and sanitation. The WC&WC project aims to contribute to the universalization of sanitation, ensuring that effluent is treated before disposal. In this way, the return of treated effluent in accordance with environmental quality parameters contributes to the preservation of receiving water bodies, providing clean water to other users. The WC&WC project brings the opportunity for the real implementation of ecological and decentralized sewage treatment systems of the constructed wetland type. The full operation of the pilot station will bring with it concrete experience regarding the efficiency of sewage treatment in constructed wetlands, allowing the assessment of the feasibility of such a system being implemented in other locations. Although there are already wetlands built in Brazil, the theoretical basis was developed for countries with a temperate climate, which implies that each installation was built empirically and produced different results for each adopted design and local climatic conditions. Therefore, it is expected that the results achieved will provide guidelines for access and universalization of basic sanitation. Professor: RAFAEL MALHEIRO DA SILVA DO AMARAL FERREIRA

Flow measurements are present in numerous processes, both domestic and productive, and in various industrial systems, such as chemical, food, oil, among others. Its importance lies in measuring fluid flow for process control or commercialization, aiming to pay inputs and taxes, among which we highlight the payment of oil royalties. Various types of meters and measurement technologies are used for flow controls, such as pressure difference measurement systems, ultrasonic systems, turbines, thermal systems and volume displacement. Among the types of meters discussed previously, the orifice plate flow measurement system stands out due to its low acquisition and process maintenance costs. The general objective of this work is to analyze the technical metrological regulation established by the ANP-Agencia Nacional de Petróleo and Inmetro-Instituto Nacional de Metrologia e Qualidade, which defines the metrological requirements for the various flow measurement systems, with the focus of this work being measuring system through orifice plate. Measurements will also be carried out on the various parameters of a measurement system and these will be compared with measurements carried out in previous years. The metrological technical guidelines for dimensional inspections will be analyzed, contained in the joint ANP/Inmetro Ordinance no. hole. The following parameters will be studied: lengths of straight sections upstream and downstream, flow conditioner, circularity of the plate and pipe, cylindricity of the pipe, surface roughness for plate and pipe, distances and type of pressure taps. The data collected will be compared with data from previous measurements and a final work report will be issued. The results of measurements to be carried out in a measurement system composed of an orifice plate and straight sections upstream and downstream will be presented. These parameters will be compared with the values established in technical regulations and technical standards, which will be evaluated regarding the parameters' compliance or non-compliance. These values will be compared with results from previous evaluations for the same measurement system, demonstrating the repeatability or otherwise of the evaluated elements and their relative wear during operationalization.

The most widespread electricity generating sources in Brazil are hydroelectric and thermoelectric, which cause environmental impacts such as air pollution and thermal water pollution. The search for renewable energy sources becomes an attractive proposal when analyzed in economic terms and the reduction of environmental damage. The objective of this project is to deepen the knowledge and technological development of solar energy in Brazil, which is still little disseminated due to political and economic reasons. This project aims to continue the PIBIC/CNPq project, in which a parabolic trough with an innovative structure was built on the premises of the UFRJ-Macaé Multidisciplinary Center. During this work, the temperature profile of the thermal fluid in the absorber tube will be investigated using thermocouple sensors and using low-cost thermal fluid, and analyzing the optimization of thermal efficiency given the different parameters investigated. Partial results were obtained by reaching temperatures of up to 97ºC at around 2pm on the day, using only water as a fluid. The execution of this project will collaborate with the improvement of thermal efficiency through solar technologies, the development of technological innovation with the proposal of a low-cost gutter, in addition to providing Engineering students with the dissemination of theoretical knowledge in practical experiences. Professor: ELISA PINTO DA ROCHA
Given the current critical pandemic scenario, measures related to strengthening the basic sanitation system are urgent. Recent legal instruments have come into force in the country with the aim of encouraging the treatment and energy use of waste, which highlights the importance of studies on the processes that involve the biodigestion of waste combined with the generation of bioenergy. In the state of Rio de Janeiro, it is estimated that the potential for methane (CH4) generation from single-stage digestion of urban waste and sewage is 55 and 3 MW, respectively. Studies carried out with sanitation waste in a combined digestion system (anaerobic co-digestion) in two stages (sequential production of hydrogen (H2) and CH4), on a laboratory scale, indicated a potential of 50 g H2/m³ CH4, with total energy yield 10.7% higher than single-stage digestion system. The two-stage digestion system presents itself as a simple technique that uses microorganisms from the sewage itself, and is promising for energy use purposes, enabling the treatment of different wastes in the same location. This makes it possible to reduce treatment costs and increase the energy supply and jobs throughout the production chain (production and distribution of biogas and biofertilizer). In this project, to determine the most appropriate operational conditions for the production of H2 and CH4 that make their energy use viable, tests will be carried out with different proportions of waste (sewage sludge and organic fraction of urban waste) at different scales to evaluation of the best mixture and scaling effect, including the characterization of the microorganisms involved in co-digestion, simulation of biogas production using mathematical models and evaluation of the use of the final product of co-digestion (digestate) as a biofertilizer in the initial growth of corn crops in soil low fertility in the state of Rio de Janeiro. Professor: ELISA PINTO DA ROCHA
This project aims to explore the application of composite materials in the Oil & Gas industry. Due to the environmental conditions present in this sector, structures usually present damage resulting from the corrosion process. The most traditional form of repair is using welding to replace the damaged part, which is a process that can have safety implications. Alternatively, repairs with composite materials have been explored due to their low cost, ease of application and efficiency. However, modeling composite materials has intrinsic difficulties due to their multiscale nature. Therefore, we want to develop tools that facilitate the design of repairs with composite materials for pipes. Professor: LUCAS LISBOA VIGNOLI
