Compression Characteristics and Fracture Simulation of Gluten Pellet.

Gluten pellets are readily broken on packaging and transportation. This study aimed to research mechanical properties (elastic modulus, compressive strength, failure energy) with different moisture contents and aspect ratios under different compressive directions. The mechanical properties were examined with a texture analyzer. The results revealed that the material properties of the gluten pellet are anisotropic, and it was more likely to cause crushing during radial compression. The mechanical properties were positively correlated with the moisture content. The aspect ratio had no significant effect (p > 0.05) on the compressive strength. The statistical function model (p < 0.01; R2 ≥ 0.774) for mechanical properties and moisture content fitted well with the test data. The minimum elastic modulus, compressive strength, and failure energy of standards-compliant pellets (with moisture content less than 12.5% d.b.) were 340.65 MPa, 6.25 MPa, and 64.77 mJ, respectively. Moreover, a finite element model with cohesive elements was established using Abaqus software (Version 2020, Dassault Systèmes, Paris, France) to simulate the compression rupture form of gluten pellets. The relative error of the fracture stress in the axial and radial directions between the simulation results and the experimental value was within 4-7%.

Abstract 1103: Theoretical basis and formula for tumor-treating fields dose-response curves

Abstract Radiotherapy dose-response curves are linear-quadratic (LQ), chemotherapy’s are generally semi-logarithmic or sigmoidal, and Tumor-Treating Fields’ (TTFields) resemble radiotherapy LQ, while the two modalities are presumed to have fundamentally different mechanisms of action (MoA) [1,2]. Radiotherapy produces single- or double-strand DNA breaks, while TTFields act on polarizable cellular structures. Thus, changing the incident electric field direction improves TTFields efficacy, killing 20% more tumor cells in vitro, with 90⁰ changes in the front-back/left-right (x,y) plane [1]. However, by the same logic, polarizable cell structures that are orthogonal to the (x,y) plane see 0 field strength and thus are unaffected by TTFields. The formula for TTFields effective dose with no direction change, given TTFields’ incident angle on the polarizable cell structure’s axis, is simply Deff = cos θ*Dnom, where Dnom is the electric field strength at the axis. The formulae for TTFields dose-response, given one, two, and three incident directions can be calculated (Mathematica v.12, WRI, Champaign, IL) as n(Dnom|cosθ1|≥k) + n(Dnom|cosθ2|≥k) + n(Dnom|cosθ3|≥k)/N, where n is the counting function, Dnom is the nominal field strength at the axis, θi the 1st, 2nd, or 3rd incident TTFields angle, k is TTFields' efficacy floor in V/cm (see below), and N is the total cell population in vivo, vitro, or silico. The formula assumes: 1) Cells are randomly-oriented in vivo [1]; 2) Polarized cell structures are straight; 3) Electric field strength is Deff not Dnom, 4) Cells are in their radiosensitive state (e.g. mitosis), 5) Reducing TTFields duty cycle/direction has no effect down to 0.25 s ([1], and unpublished data), and 6) TTFields’ minimum efficacious field strength Deff = ~0.75 V/cm for cell structures perfectly aligned with the incident TTFields angle (cf. low dose V/cm data points in MDA-MB-231, F-98, B16F1, and H1299 empirical dose-response curves [1,2]). With feasible TTFields transducer array placements on the head or torso, it is relatively easy to achieve changes of direction in one (x,y) plane, but difficult to achieve an additional change of direction in the z-plane. For a nominal TTFields dose Dnom of 2 V/cm, only a 22⁰ change of direction off the (x,y) plane is necessary to kill the cells with Deff below the efficacy threshold, with Dnom = 1.5 V/cm, a 30⁰ change is needed, and with Dnom = 1 V/cm, a 49⁰ change is needed. In sum, we have derived TTFields’ dose-response formulae from first principles, which differentiates them from those of radiotherapy and chemotherapy, and, toward achieving 100% TTFields efficacy as a monotherapy, given motivation and guidelines for adding an additional TTFields’ change of direction per duty cycle.1.Kirson, E.D., et al., Proc Natl Acad Sci U S A, 2007.2.Moser, J.C., et al.,.Cancer Res, 2022.

The geomechanical properties of soils treated with nanosilica particles

This study examines the effect of nanosilica (NS) additive to improve the mechanical properties of clay, clayey sand, and sand. The engineering properties of the soils were investigated through Atterberg limits, compaction, unconfined compression, ultrasonic pulse velocity (UPV), freeze-thaw, and direct shear tests. The NS content varied from 0% to 0.7% and cement content was 5% and 10% by the dry weight of the soil. The curing period varied from 7 d to 150 d. The consistency, compaction, and strength properties of the soils were affected by the presence of NS and cement. The optimum NS contents in clay specimens with 5% and 10% cement were 0.5% and 0.7%, respectively. It was 0.7% in sand specimens with both cement ratios, as well as 0.3% and 0.7% in clayey sand specimens with 5% and 10% cement, respectively. In terms of freeze-thaw resistance, clayey sand specimens containing 0.5% NS and 10% cement had the minimum strength loss. Exponential relationships existed between the ultrasonic pulse velocity (UPV) and the unconfined compressive strength (UCS) of soil specimens having the same curing period. The shear strength parameters of the soils also improved with the addition of NS. Scanning electron microscope (SEM) images demonstrated that cement and NS contributed to the improvement of the soils by producing a denser and more uniform structure. It was concluded that the minor addition of NS could potentially improve the geomechanical properties of the soils.

Influence of cutting damage on the bending strength of Ti&lt;sub&gt;2&lt;/sub&gt;AlC MAX phase machinable ceramics

Ti2AlC MAX phase ceramics are excellent candidates for high-temperature heat resistant materials. In addition, they are machinable using cemented carbide tools. However, heavy machining induces many surface cracks, reducing the mechanical strength and reliability of ceramic parts. Herein, we investigated the influence of the machining process on the bending strength and microstructure of Ti2AlC ceramics. Nearly fully dense Ti2AlC ceramics with elongated grains were machined using a carbide end mill in brittle mode, producing numerous cracks; however, the roughness of the ceramic was similar to that of tool steel cut in ductile mode. Despite its rough surface, the bending strength of the machined Ti2AlC was only slightly lower than that of polished Ti2AlC. The cracks in the machined Ti2AlC ceramics were induced with a kinking structure; however, they stopped at a length equivalent to one grain. The minimum strength of the machined Ti2AlC ceramics with a fracture toughness of 6.9 MPa·m1/2 was estimated by assuming a machining through-crack shape that was as deep as the maximum grain size. Cutting damage was limited to a single grain; thus, the bending strength of the machined Ti2AlC was not significantly reduced.

The effect of laser surface textures on the adhesion strength and corrosion protection of organic coatings - Experimental assessment using the pull-off test and the shaft load blister test

Adhesion is necessary for an effective corrosion protection of metallic surfaces through organic coatings. Even the best anticorrosive coatings fail if it is not well adhered to the substrate. Laser surface texturing (LST) process has been widely used for enhancing adhesion between coatings and steel surfaces in various applications. In addition, recent researches have proven that LST is an effective option for pretreatment of steel surfaces prior to organic coating deposition. This work reports an investigation on the adhesion strength of organic coatings deposited onto AISI-A36 carbon steel laser-textured surfaces. Nanosecond LST via the direct laser writing (DLW) method was used to fabricate V-shaped grooves on the steel surfaces. The distance between consecutive grooves was varied to obtain different surface topographies with controlled surface textured area (TA) ranging from 10 % to 60 %. Conventional bead-blasted surfaces were used as a reference. Surface morphology and topography were characterized through roughness and tortuosity. The frequently used pull-off test (ISO 4624) and a shaft load blister test (SLBT) were used to determine the adhesion of the epoxy coating. In addition, accelerated corrosion tests were carried out to assess the effects of the laser textured surface conditions on the corrosion propagation. After running the pull-off test, all the surfaces' conditions exceeded the minimum pull-off strength value of 5 MPa stated in ISO 12944-9. The results for the SLBT showed that the adhesive strength is highly influenced by the laser-textured area. The geometrical aspects of the groove structure promote phenomena such as mechanical interlock and mechanical hooking of the coating, which affect the adhesion failure mechanism of the organic coating during the test. For lower TA, the crack propagation occurs mainly at the coating/steel interface. However, increasing the TA shows that the crack propagation is stopped near the V-shaped grooves due to the complex shape and must deviate inside the coating for further propagation. Finally, adhesion strength results were correlated with coating delamination rates and an indirect relationship was found.

Soğuk Haddelenmiş Strenx 700 CR Çeliğinin Nd:YAG Lazer Kaynak Faktörlerinin Taguchi Yöntemi ile Optimizasyonu

In this study, cold rolled Strenx 700 CR steel with a minimum yield strength of 700 MPa, which is typically used in load bearing structures to produce stronger and lighter structures, is butt welded with Nd:YAG laser welding. The effect of welding factors on tensile strength is investigated by using laser power rate (20%, 40% and 60%), pulse duration (2, 4 and 6 ms) and pulse frequency (3, 5 and 7 hz). By using Taguchi L9 orthogonal experimental design, the number of experiments, which should be 27 when full factorial, is reduced to 9 experiments. The tensile strength test results are optimized by the Taguchi method's larger is better control characteristic. The optimum test combination for maximum tensile strength is determined as A3B2C2 (60%-4 ms-5 hz). The effect of the welding factors on the tensile strength results is analyzed using the analysis of variance (ANOVA) method and it is found that the most effective factor is the laser power rate with 84.26%.

Mechanical Properties of Plastic Concrete Made Using Recycled Aggregates for Paving Blocks

In developing countries, the management of waste continues to be a major challenge, especially in urban areas. One of the major concerns for today’s world is the management of plastic and construction and demolition (C&amp;D) wastes which are increasing with urbanization and population growth. This study aims to explore the possibility of the use of plastic waste as a binder and recycled aggregates obtained from C&amp;D waste to produce concrete paving blocks. The mechanical investigation was carried out to find the optimum content of plastic waste to prepare the plastic concrete. Three different concrete mixes were prepared with plastic contents of 30%, 40%, and 50% by the weight of aggregate. To evaluate the mechanical properties of plastic concrete, compression, flexural, and ultrasonic pulse velocity (UPV) tests were performed on the prepared samples. Cubical specimens of 36 x 40 x 40 mm for compression tests and prismatic specimens of 36 x 40 x 120 mm for flexural tests were cut using a saw from the paving blocks of size 36 x 137 x 290 mm. The results indicated that the strength of plastic concrete increased with the increase in plastic content. The maximum compressive and flexural strength was achieved at 50% plastic content, which was 40.52 MPa and 10.13 MPa, respectively. The compressive and flexural strengths of plastic concrete were compared with the minimum strength requirement specified by various standards specification such as American, Canadian, and Chinese. It was found that plastic concrete with 50% content of plastic waste meets the minimum criteria of mechanical strengths specified in these standards. Presently, many countries of the African continent are facing severe problems of plastic waste. As per the findings of this study, the use of waste plastics in molten form as the only binder in the development of concrete paving blocks could offer a solution for such countries to beneficially manage the plastic waste.

Stiffening surface lowers ice adhesion strength by stress concentration sites

Mechanically softening materials have been intensively investigated to reduce ice adhesion strength based on the adhesion failure mechanism. Achieving icephobic surfaces with both low ice adhesion strength and mechanical robustness is challenging. The surface stiffening-induced stress concentration sites on elastomer should be possible to improve the mechanical robustness and lower the ice adhesion strength simultaneously, as it can build material inhomogeneity (stiffness mismatch) and geometry irregularity-induced cracks on the surface layer of elastic materials. To reveal this hypothesis, the stress concentration sites are introduced to obtain the robust low ice adhesion surface (RLAS) by implementing rigid nanocomposites with the elastic modulus of GPa scales (e.g. silica nanoparticles, SiO2NPs, ca. 68.9 GPa) into the surface layer of elastomers (e.g. polydimethylsiloxane, PDMS, ca. 2.7 MPa). The effects of the material inhomogeneity (stiffness mismatch) and geometry irregularity-induced stress concentration sites on the reduction of ice adhesion strength are revealed. The minimum ice adhesion strength of the RLAS is down to 10.5 kPa, and its ice adhesion strength remains at 13.8 kPa after 25 icing/deicing cycles. Originating from abundant potential crack initiation sites and stiff nanoparticles, our designed nano-composite materials remarkably lower the ice adhesion strength and are over 2-fold mechanically stiffer than pure elastomer. This strategy offers an unconventionally hardening surface approach for designing icephobic materials with combined durability and robustness.

Weibull stress method to determine the minimum required strength to improve the actual reliability

AbstractThe method to determine the minimum strength that a product must present to improve the product's reliability from its actual R(t) to a desired R(t2) index are given. The method can be performed in both the normal and accelerated scenarios. It can be done by using either complete failure time data or based only on the applied stress range. The addressed minimum strength that corresponds to the R(t2) index is then used in the stress/strength reliability function to determine the corresponding reliability R(t/S,s) index. From the comparison between the R(t2) and R(t/S,s) indices, we found they are similar only for high reliability indices (say R(t) &gt; 0.90). For lower indices their difference is significant, implying more research must be undertaken. In the application a zero accelerated test plan (ZATP) is performed to experimentally demonstrate the improved product presents the desired R(t2) index. Finally, because by applying the proposed method we always can reproduce the product's average, then the formulation to determine the capability Cp and ability Cpk indices of the R(t2) index is also given.

Strain-rate dependent crystal plasticity model and aluminum softening/hardening transition

Hardening or softening associated with the increase of dislocation density is correlated with strain rate and dislocation density. Taking aluminum as a model material, we investigate the strain rate and dislocation density dependence of the strength and the accompanying hardening or softening effect upon a dislocation increase. This investigation is enabled by employing a newly developed crystal plasticity model, which is validated against the mechanical behaviors in an extremely wide strain rate range, and featured by a parameter-free mobile dislocation fraction law based on the exponential distribution of dislocation link lengths and an averaged dislocation velocity model that considers both thermally-activated waiting mechanism and drag-dominated running mechanism. Results show that at different strain rates, the material strength varies with a universal feature that it first softens as the dislocation density increases from a sufficiently low initial value, and then hardens after reaching the minimum strength, where the critical dislocation density separating the softening from hardening regimes increases with the strain rate. Microscopically, the strength dependence on dislocation density and strain rate originates from their influence on the two competing effects of a dislocation increase, where the hardening effect comes from the higher resistance to dislocation slip by increased forest dislocations while the softening effect comes from the larger quantity of mobile dislocations. These two competing effects are quantitatively evaluated by the crystal plasticity model and are further cast into the competition between the partial derivatives of normalized dislocation velocity and of normalized mobile dislocation density, and the governing equation for the critical dislocation density is thus furnished by balancing these two competing effects. Further, a complete map in the entire space of strain rate and dislocation density (ε̇,ρ) is constructed for the zones of dislocation hardening or softening, where the zone-boundary curve for critical dislocation density exhibits a two-stage character and it agrees well with the available experimental data. Such a map is expected to help predict the trend for strength evolution under different serving conditions and also guide the material design according to the requirements for strength variation in service.

Experimental research on the high‐temperature compression mechanical properties of carbon/phenolic composites in rapid carbonization conditions

AbstractThe structural characteristics of fiber‐reinforced plastic composites are usually determined by ablation, but bearing capacity is also a key parameter that should be clarified in aerospace engineering. Needle‐punched carbon/phenolic composites are most commonly used as the inner material of solid rocket motor nozzles, and the mechanical properties thereof are dynamic and difficult to obtain at high temperatures. A radiation‐heating mechanical testing machine with split‐test chambers was designed to test the in‐plane compression properties of the composite at different degrees or pyrolysis and temperatures. The results show that the final weight‐loss rate was 25.5%. During the loading process, the composite had a linear elastic mechanical response and brittle fracture failure, and the compressive strength was 218.9 MPa at room temperature. At different holding times, the higher the temperature, the higher the weight‐loss rate, the higher the graphitization degree of the specimen, and the lower the degree of disorder of the carbon matrix. Thus, the minimum compressive strength was found to be 23.42 MPa at 600°C, and the maximum was 60.16 MPa at 1800°C after high‐temperature pyrolysis. The present work provides a reference for the refined design of solid rocket motor nozzles.

Retention Behaviour of Heavy Metals from Industrial Sludge Amended with Admixtures to Use Them as Liners for Landfill Facilities

The solidification of contaminants within the soil/waste has proved to be a versatile technique to de-contaminate them and make them usable for several applications. In this method, the development of binder provisions leads to the conversion of the environmentally unstable condition of waste materials into a nearly stable material. Further, these materials pose a minimum threat that can be absorbed into the environment. Normally lime/cement and other pozzolanic materials are used as binder materials. In this work, it is proposed to use the efficiency of binding fly ash to improve the unconfined compressive strength (UCC) of soils, particularly during the curing period. This is because improvement in strength is a reflection of the improvement of bonding soil particles. Fly ash as the main source material, in addition to a minor proportion of cement and lime, is used to determine the strength. UCC test results revealed that as the percentage of fly ash increases there is an increase in compressive strength. It is also observed that with an increase in lime content and an increase in cement content, the UCC strength also increases. The strength in cement-stabilized compacted specimens is more compared to lime-stabilized mixtures. To confirm that the improvement in strength is related to the solidification of contaminated metals, particularly for soils containing copper and chromium, the stabilized mixture is tested for the leaching of these metals. Leaching tests were conducted on various stabilized mixtures at different curing periods. The leachate was examined for metal ion concentration using Atomic Absorption Spectrophotometer. The leaching behavior of heavy metals from different proportions of soil matrix revealed that with an increase in lime or cement percentage, a decrease in leachability is observed. It is found that the leaching of heavy metals from cement-stabilized soils was lower than in lime mixture combinations. However, minimum strength improves the solidification and retention of heavy metals effectively.

Выбор и оптимизация перспективной конструктивно-силовой схемы фюзеляжа из полимерных композиционных материалов беспилотного летательного аппарата

Fuselage is the main element of unmanned aerial vehicle, which parameters optimization could increase the structure strength and weight characteristics. Both the modern polymer composite materials with high specific characteristics and the advanced power circuits are able to assist in solving this problem. Selection and optimization of the structural power scheme of the unmanned aerial vehicle fuselage appear to be an urgent task. Structure loads under various flight and maneuver modes were analyzed. Eight fuselage structural power schemes were designed including classic, grid, auxetic and biosimilar structures. Operation of the power circuits made of carbon fiber exposed to the obtained loads was considered, and their stress-strain state was determined. Rational scheme was selected according to the minimum mass and maximum strength criteria, for which the main parameters were determined. Advantage of the promising power circuit over the classical one was shown. The results obtained are part of a comprehensive study of the promising structural power schemes made of polymer composite materials.

Comparative Study of Welding Material Elasticity with the SMAW Process for 2G Positions Between Before and After Using Welding Machines with Augmented Reality Technology

The high cost of certification and the low pass percentage in welding certification are common issues for beginner welders. The use of Augmented Reality (AR) technology is expected to solve these issues. The results of the penetrant, bending, and tensile tests showed that the welder who had used the AR welding machine produced better welding specimens than before they practiced using the AR welding machine. The penetrant test after beginner welder practiced using the AR welding machine produces rounded defects with a defect size of 1,44 mm (accepted by ASME Section V), whereas before they practiced using the AR welding machine it produces defects that cannot be accepted by the criteria. The maximum open discontinuity length in the bending test on the welded specimen after welder practiced using the AR welding machine is 2,90 mm (accepted by ASME Section IX), whereas the bending test before welder practiced using the AR welding machine is not accepted by the citeria. The tensile test results after welder practiced using the AR welding machine were 410,00 and 455,66 N/mm2 for the maximum tensile stress. This value exceeds the minimum tensile strength of SA-36 carbon steel, which is 400 N/mm2. When compared to the specimen before the welder practiced using the AR welding machine, the modulus of elasticity produced after the welder practiced using the AR welding machine is also smaller, indicating that the material has better elasticity. Based on the results of the tests, it can be seen that the AR welding machine can be used for the implementation of competency certification because the quality of the weld results is better, there are fewer risks (sparks, eye irritation, and burns), and the use of welding consumables is reduced

Impact of molecular architectures on mesogen reorientation relaxation and post-relaxation stress of liquid crystal elastomers under electric fields

Applying electric fields to liquid crystal elastomers (LCEs) has attracted attention as a fast and energy-efficient actuation method for soft robotics. It is helpful to predict the minimum electric field strength that can drive the mesogen reorientation and the time required for the reorientation of LCEs with specific molecular architecture to optimize LCE electrical actuation. In this study, molecular dynamics (MD) simulations of main- and side-chain LCE systems under an applied electric field were performed, and the relaxations of stress and orientational order were observed. The minimum electric field strength that can drive the reorientation for each LCE molecular system was estimated. The time required for reorientation follows a power law of the electric field strength, and the reorientation time for side-chain LCEs is much shorter than that for main-chain LCEs. The behavior of the relaxation value of stress with respect to the electric field strength differed markedly between the main- and side-chain LCEs. These results suggest that designing LCEs at the molecular architecture level and using different LCE molecules in different actuation sites are essential to more precise soft robotics.

Seaweed Pellets as a Renewable Fuel Feedstock

Seaweed can be a desirable source of renewable energy or fuel after it has been processed by combustion, thermochemical conversion by gasification, pyrolysis, or hydrothermal liquefaction (HTL) or biochemical conversion routes like anaerobic digestion (AD). This work explores how well the measured properties of seaweed pellets match the specifications for the various fuel and energy conversion options listed. Blends of hay, wood chips, sawdust, and seaweed were pelletized. Eight pellet blends with dominant seaweed content and minimum acceptable mechanical strength and stability were produced and their physical and chemical properties were reported. The seaweed pellets had an energy content of around 14 MJ/kg, and each pellet could withstand almost 200 N of compression force. Their water content was around 5% or less and their ash content was around 20–34%. According to the results, a higher wood content increased the energy content of the pellets. Among those properties measured in this project, none of them contradicted the typical specifications of combustion, HTL, and AD. However, the low water content and low strength of some pellet types were unable to meet the specifications for certain types of gasification and pyrolysis.

Mechanical characterization of gypsum mortars with waste from the automotive sector

The construction sector is one of the main industries generating greater environmental impacts. In this sense, the European Commission is forcing the sector to implement alternative measurement and strategies to tackle this situation and bring the sector to a circular economy. One of the adopted measures is the use of recycled materials to produce construction materials and products. In this sense, many scientific works have been conducted analyzing the incorporation of different waste categories in gypsum products. In this sense, the main objective of this research is to characterize new gypsum-based materials that incorporate waste from the automotive sector. For this, mixed waste (containing polyurethane, cardboard and fiberglass) obtained during the production of automobiles’ backboards was used. A total of 171 specimens were produced incorporating different percentage and size of mixed waste. These specimens were tested according to the bulk density, superficial hardness, and flexural, compressive and bonding strengths. Results show that it is possible to incorporate up to 11% of mixed waste overpassing the minimum strength values established by the regulations. In addition, the lightness of the material and its compression and flexion behavior improved considerably compared to the reference specimens without any waste addition.

Evaluation of sisal fiber and aluminum waste concrete blend for sustainable construction using adaptive neuro-fuzzy inference system

This research study presents evaluation of aluminum waste-sisal fiber concrete’s mechanical properties using adaptive neuro-fuzzy inference system (ANFIS) to achieve sustainable and eco-efficient engineering works. The deployment of artificial intelligence (AI) tools enables the optimization of building materials combined with admixtures to create durable engineering designs and eliminate the drawbacks encountered in trial-and-error or empirical method. The features of the cement-AW blend's setting time were evaluated in the laboratory and the results revealed that 0–50% of aluminum-waste (AW) inclusion increased both the initial and final setting time from 51–165 min and 585–795 min respectively. The blended concrete mix's flexural strength tests also show that 10% sisal-fiber (SF) substitution results in a maximum flexural strength of 11.6N/mm2, while 50% replacement results in a minimum flexural strength of 4.11N/mm2. Moreover, compressive strength test results show that SF and AW replacements of 0.08% and 0.1%, respectively, resulted in peak outcome of 24.97N/mm2, while replacements of 0.5% and 0.45% resulted in a minimum response of 17.02N/mm2. The ANFIS-model was developed using 91 datasets obtained from the experimental findings on varying replacements of cement and fine-aggregates with AW and SF respectively ranging from 0 to 50%. The ANFIS computation toolbox in MATLAB software was adopted for the model simulation, testing, training and validation of the response function using hybrid method of optimization and grid partition method of FIS at 100 Epochs. The compressive strength behavior is the target response, and the mixture variations of cement-AW and fine aggregates-SF combinations were used as the independent variables. The ANFIS-model performance assessment results obtained using loss function criteria demonstrates MAE of 0.1318, RMSE of 0.412, and coefficient of determination value of 99.57% which indicates a good relationship between the predicted and actual results while multiple linear regression (MLR) model presents a coefficient of determination of 82.46%.
