Objective: To evaluate the performance of a controlled release fertilizer on the vegetative and productive development of coffee trees in production.
Theoretical framework: The use of slow, controlled release fertilizers or smart fertilizers can allow the reduction of fertilization operations, in addition to being characterized by the availability of nutrients to plants at the correct time, with the consequent reduction in maintenance expenses, labor of work and fuel.
Method: A trial was conducted in Alto Paranaíba, Minas Gerais, during 4 harvests, to evaluate the performance of a slow-release fertilizer on the vegetative and productive development of coffee trees in production, as well as the impacts of this technology on the scaling of mechanized operations in property.
Results and conclusion: With the use of slow-release fertilizers, it was concluded that: slow-release potassium nutrition reduces the competitive effect of potassium with Calcium and Magnesium; productivity gains are obtained when compared to the use of conventional fertilizers; there is an increase in coffee yield; at a rate of 80% of the dose, there are advantages in the nutrition of the coffee plant, especially in old crops; There is a reduction in the number of machine hours worked in the agricultural year with a consequent reduction in production costs, making it possible to redistribute mechanized operations, reducing labor and the volume of operations in the months that demand the most services.
Implications of the research: With the results of the research, over two biennia, it was possible to identify the positive factors of using slow-release fertilizers for coffee trees, both in biometric and productive aspects and in the optimization of mechanized operations in a coffee farm cultivated in the cerrado miner.
Originality/value: a better understanding of the effects of using slow-release fertilizer technology to increase productivity and better economic and environmental performance in coffee agribusiness.

Theoretical framework: Volumetric models are a crucial tool for forest management, as they use them to estimate the total volume of the forest. Objective: The study aimed to adjust a volumetric model to estimate commercial volume in a dense rainforest located in the municipality of Ferreira Gomes AP, Brazil. Method: Cubing data from 103 sample trees, from 5 species, were used to adjust 7 volumetric models, 5 of which were linear and 2 were non-linear. Results and discussion: After analysis, it was found that all models presented a good fit to the data, however the non-linear models presented the best statistics. Finally, the Schumacher and Hall model generated the best equation for estimating commercial volume in the Amapá national forest. Implications of the research: There is a general equation to estimate the volume of commercial species in the Amapá national forest. Originality/Value: Volume equations are essential for management plans in Amazonia, therefore, this is the first equation available for volume estimation in the Amapá national forest.

Objective: The present work aimed to evaluate the callogenesis of murici-pitanga in different explants and growth regulators. since this species has great medicinal, environmental and economic importance, however the cultivation process and extractivism make its propagation difficult. Therefore, in vitro cultivation provides conditions that can optimize its propagation. Among the techniques used in in vitro micropropagation, callogenesis allows the regeneration of tissues, organs or plants, becoming a cultivation alternative for the species under study.
Method: Explants from seedlings cultivated in vitro were inoculated in MS 1/2 medium with different types, concentrations and combinations of growth regulators, namely: zygotic embryos under 6-benzylaminopurine x α-naphthaleneacetic acid (BAP x ANA) (0.0 ; 11.1, 22.2 and 44.4 µM); leaf and stem segments under NAA (0.0; 13.42; 26.85 and 40.27 µM) and root and leaf segments under 2,4-dichlorophenoxyacetic acid (2,4-D) (0.0; 2. 26; 4.52; 9.05 and 18.10 µM), with subcultures in cell suspensions (0.0; 4.52; 9.05; 18.10 and 3620 µM) and callus growth curve (4. 52 µM).
Resultsandconclusion: The percentage of induction and mass of fresh callus matter were evaluated. The callogenesis of murici-pitanga occurs more efficiently in the root segment in a medium supplemented with 4.52 µM of 2,4-D. Where, the calluses presented friable characteristics, in addition to better averages of induction percentage and fresh matter mass. For cell suspension, a concentration of 4.52 µM of 2,4-D is indicated, and in the growth curve, the best period for callus subculture may occur on the 56th day of cultivation, established based on the callus growth pattern sigmoidal with three distinct phases. Therefore, the murici-pitanga can be regenerated through calluses originating from root segments.
Originality/value: Studies that address the in vitro propagation of murici-pitanga are scarce, and the present work reports significant results, with new explant options and different types of growth regulators to be used. In addition to advances in studies of callus subcultures with great potential for regeneration. These results become important, since the species needs techniques that facilitate its propagation, and could support future morphogenetic studies, obtaining secondary metabolites, in addition to establishing a regeneration protocol via somatic embryogenesis.

Purpose: The present study aimed to study the catchment basin of the Meia Ponte River, analyzing land use and occupation, verifying whether permanent preservation areas are being preserved and which activities predominate in the region. Theoretical framework: Inadequate land use and the release of effluents can harm the quality and quantity of water available for use. Therefore, the sustainable exploitation of natural resources is necessary, combining economic development and environmental preservation. Methods: Physicochemical analyzes were carried out, evaluating the following parameters: pH, turbidity, color, temperature, biochemical oxygen demand (COD) and total phosphorus. The location chosen to carry out the collections was the water collection point for public supply from the Meia Ponte River. In addition to data obtained by the mapbiomas program using QGIS software. To delimit the basin, data from the Goiás geographic information system (SIEG) was used. Results and conclusion: The results showed that more than 60% of the basin area studied was pasture area, showing that there is degradation in the basin and satellite images showed that there are also areas of APP that are not properly preserved. Furthermore, water collections during the rainy season showed a high turbidity value, indicating that solids are being transported into the water body. Research implications: The main contributions are related to the eutrophication process and the environmental impacts caused by human actions. Originality/value: Verification of the impacts of human actions on land use and occupation on water quality in the Meia Ponte river region.

Objective: This study aimed to characterize malt bagasse obtained as the main residue from beer processing.
Theoretical benchmark: Malt bagasse is an agro-industrial waste with attractive nutritional characteristics, such as dietary fibers and proteins, intended for low or no added value purposes. In this sense, malt bagasse can nutritionally enrich various food products.
Method: The malt bagasse was dehydrated and then analyzed for its central characteristics (moisture, ash, proteins, dietary fiber, lipids, carbohydrates, energy value and mineral composition), physicochemical (pH, acidity and aw), bioactive (phenolic and antioxidant content) and microbiological.
Results and conclusion: As main results, malt bagasse showed high dietary fiber content (37,70 g/100 g) and high protein content (18,24 g/100 g), antioxidant capacity by the DPPH method with results expressed in EC50 as being 4,68 mg/mL and total phenolic content 360,99 mg EAG/100 g dry sample.
Implications of the research: The results of this study show a promising potential in the reuse of malt bagasse, to quote, in the incorporation into food for human consumption.

Objective: the scope of this work is to present a numerical-computational model for transient dynamic nonlinear analysis of frames with geometric nonlinearity and semi-rigid connection. Methodology: the equation of motion, which describes the structural dynamical system, is solved by the a-Generalized direct integration method associated with the standard Newton-Raphson method. The structures are discretized through the co-rotational formulation of the Finite Element Method considering the Euler-Bernoulli beam theory. The semi-rigid connection of structural members (beam-column and beam-support) is simulated by a connection element with zero length, which is described in terms of axial, translational and rotational stiffness. Results and conclusion: From the numerical results of three structural systems (bi-fixed beam, L-shaped frame, and single-story frame) obtained with the free Scilab program, it is concluded that the definition of the type of connection is an important factor to be considered in the analysis of frames subjected to dynamic loads. Furthermore, structural damping, which is a measure of energy dissipation, drives the structure from a vibrating state to a resting state. Research implications: Structural Engineering has been designing systems that cannot be analyzed and dimensioned without dynamic effects being considered. lack of knowledge of the levels and characteristics of the dynamic response can lead to system failure during the application of repetitive loading due to accumulation of structural damage. In this sense, the numerical model can represent a valuable engineering tool when it comes to the dynamic analysis of plane metallic structures with geometric nonlinearity.
