According to the World Health Organization, 80% of the population makes use of traditional practices in Primary Care. Brazil’s National Policy of Integrative and Complementary Practices considers medicinal plants to be the most inserted practices in society, because they have continually been present to the family and religious environment, which apply their knowledge. The objective of this work was to know the usual integrative and complementary practices in quilombola communities of the semi-arid region of Piaui.

Nowadays, databases are very useful for saving or registering data, information or events. Forecasting studies, autonomous decision-making control system became more accurate and easy to implement since databases had been invented. Artificial Intelligence applications show more and more effective when it comes to solving problems conventional computational algorithms cannot handle. They also show to be useful when the problem’s exceptions are unknown or cannot be easily determined.

Construction systems in the construction industry have evolved significantly in recent decades. However, simplified building systems can also be found that have low construction costs, as well as allowing to meet the housing deficit demand for low-income populations. In this sense, this research aims to present the applicability of the use of soil-cement concrete and cellular concrete in the construction of housing units that serve low-income populations in the state of Amazonas, in urban and rural areas.

Electricity is practically indispensable for the development of a country.In this sense, for its production, it is currently widely used non-renewable natural resources such as oil, gas, water, coal, uranium and others.Aiming at the environmental protection and sustainability of these resources, it is necessary to implement measures to implement electricity generation from renewable sources such as photovoltaic and wind energy.The objective of this work is to address the renewable sources of electricity generation using the photovoltaic and wind energy matrixes focused on the sustainability

Background: While performing a Spine surgery, surgeon bends over the patient on the operative table and has to adapt uncomfortable postures and perform surgical manoeuvres for long duration of time. This unsuitable ergonomic environment results in multiple musculoskeletal complaints being experienced by the surgeon himself.

Food security and cash availability are some of the present major concerns of many countries of the world since the outbreak of the deadly Corona virus (COVID-19) disease. This study examines the production of major cash crops in the 16 West African countries from 1961 to 2018 using the Crossover Analysis of Variance (ANOVA) design with a view to examine the relationship between the level of production among the countries. Four variables were considered for this study namely the Area, Item, Unit and the Flag description.

The Optical Character Recognition (OCR), together with another inspection techniques, is the mostly method utilized in the PCB industry. This work have as objective to identify text characters in five main PCBs template samples. Further, through a “Guide User Interface” (GUI) developed in MATLAB software, estimate the parameters as the quantity of detected texts, plot the graphic with the mean time average, and classifying the text character detected. Results showing the efficacy detection capacity of the OCR algorithm also are described in this work.

The goal of this project papers is to study the whole three phase grid connected system fed by PV panel using an MPPT algorithm to feed the maximum available power at different environmental conditions and to implement the same in Matlab/Simulink. Firstly, boost converter and MPPT implementation and secondly, the grid-side inverter and grid interconnection fed by a DC source. In the first part, the PV array was simulated in Matlab/Simulink and various tests carried out to determine the dependence of IV and PV curves on irradiance and temperature.

Despite the widespread use of technology in several agricultural activities, most of the production processes in fish farming are not automatized. That includes water quality control and feed supply, which are related given that water temperature is key to determine how much feed should be dispensed in the fishponds at a given time. In this work, we describe a system to estimate the water temperature in a fish farm via unmanned aerial vehicles (UAV) and show how it can enhance the fishponds daily management.

Image recognition is a recurring theme in the field of computer vision and it currently borrows some elements from Artificial Intelligence also. However, images are often dealt with in a specific manner, with the algorithms exploring some feature of the said image (be it during pre-processing or during image recognition). Such as is the case when, for instance, some specific algorithms are used for recognition purposes (ranging from biometric recognition to medical images recognition and also the recognition of some defects in electrical / electronic circuit boards), to name just a few.
