Published: September 2022

Patin fish oil (PFO) contains a high level of polyunsaturated fatty acid that has beneficial effects on the human body, such as preventing various cardiovascular diseases, maintaining body fat composition, and aiding in human brain development. PFO can be developed as patin fish oil emulsion (PFOE) and used as a dietary supplement. Given its beneficial value, PFOE is at risk of being adulterated with -quality oils. Therefore, authentication is crucial to guarantee its quality and safety. However, authenticating PFOE is difficult because its physical appearances are masked by the emulsion component. This study aims to authenticate PFOE using Fourier transform infrared (FTIR) spectroscopy combined with chemometrics. Adulteration models were prepared using palm oil (PO) as an adulterant. All samples were analyzed using ATR-FTIR spectroscopy at 650–4000 cm−1. Chemometric techniques such as discriminant analysis (DA), partial least square regression, and principal component regression (PCR) were adopted for . Results showed that DA successfully discriminated PFOE from the adulterant. PCR within the normal spectrum of 1004–2936 cm−1 produced the best values of 09846 highest R2cal, 0,9073 R2pred, 0,0565 lowest root mean square error of calibration, and 0,1330 root mean square error of prediction. Therefore, FTIR spectroscopy combined with chemometrics is a rapid, accurate, and suitable method for distinguishing pure PFOE from PO adulterant.

Published: September 2022

Software Defined Networking (SDN) is an important technology that enables a new approach to how we develop and manage networks. SDN divides the data plane and control plane and promotes logical centralization of network control so that the controller can schedule the data in the network effectively through the OpenFlow protocol. The performance and capabilities of the controller itself are important. The impact of network topology type on controller performance can be very significant. In order to have better communication in SDN, it is essential to have an analysis of the performance of specific network topologies. In this paper, we simulate ONOS and RYU controllers and compare their different network parameters under the proposed complex custom Tree-based topology. A network topology has been designed using a Mininet emulator, and the code for topology is executed in Python. From the throughput, packet transmission rate, and latency analysis, the ONOS controller displayed better results than RYU, showing that it can respond to requests more efficiently under complex SDN topologies and traffic loads. On the contrary, the RYU controller provides better results for the less complex SDN networks.
THE IMPACT OF HUMAN CAPITAL VALUE ON HUMAN CAPITAL EFFICIENCY AND BUSINESS PERFORMANCE
Authors: Veselinović Nemanja , Krstić Bojan , Rađenović Tamara
Published: September 2022

In the knowledge economy era, human capital is a part of intellectual capital and a significant factor in enterprise competitiveness. The importance of human capital is often diminished due to the accounting expression of investments in human resources in the income statement as a cost (expenditure) component. This paper points to the fact that the cost of human resources is an investment that affects the growth of the business performance of an enterprise. Hence, the aim of this paper is to examine the impact of human capital value on human capital efficiency and business performance indicators, such as sales revenue (SR), earnings before interest and taxes (EBIT), and EBIT margin (EBITM). To examine this impact, empirical research is conducted on a sample of 24 companies with the highest brand value for the period 2012-2019. The regression analysis results show that sales revenue and EBIT grow by 0.77% and 1.1% respectively as human capital value grows by 1%. Additionally, findings reveal that the growth of the human capital value negatively affects the values of human capital efficiency indicators and EBIT margin in the sample of examined enterprises.
THE FUNDAMENTAL BREACH OF CONTRACT OF SALE UNDER THE CISG
Authors: Ay Yunus Emre
Published: September 2022

While a breach of contract implies the failure of one party to fulfil the obligations arising from the contract, the fundamental breach of contract is an aggravated form of breach of contract. The concept of the fundamental breach of contract of sale is recognized in Article 25 of the CISG (UN Convention on Contracts for the International Sale of Goods, 1980). In an ordinary breach of contract of sales, the applicable legal remedies are ordinary legal remedies (such as substitution of goods, damages). In case of a fundamental (substantial) breach, the unilateral declaration of termination of the contract of sale is used as the last resort (to void the contract). Given that it is perceived as a special aggravated type of breach of contract of sale, the fundamental breach has to be carefully analysed in more detail.
TAGUCHI OPTIMIZATION OF MULTIPLE PERFORMANCE CHARACTERISTICS IN THE ELECTRICAL DISCHARGE MACHINING OF THE TIGR2
Authors: Akıncıoğlu Sıtkı
Published: September 2022

Electrical discharge machining (EDM) provides many advantages for the shaping of metallic materials. It also provides better surface quality for Ti alloys used in the defense industry.  In this study, experiments were carried out with different EDM parameters using the Titanium (Gr2) alloy. A number of novel industrial processes have been developed as a result of advances in technology. For a product to be developed, these novel approaches must be utilized to determine optimum parameters. The Taguchi method was applied in the experiments with EDM. The impact the test parameters had on the performance characteristics of tool wear rate, material removal rate, depth, and surface roughness were analyzed by the variance analysis (ANOVA). Quadratic regression analyses were carried out to reveal the correlation between the experimental results and the predicted values. According to the ANOVA results for material removal rate (MRR), tool wear rate (TWR), depth, and surface roughness, the most effective factor was amperage, at 99.66%, 99.56%, 87.95%, and 81.12%, respectively.  The best value for average surface roughness was determined to be 3.29 µm obtained at 120 μs time-on, 8 A, and 40 μs time-off.
ASSESSMENT OF THE QUADRUPLE INJECTION STRATEGY OVER TRIPLE INJECTIONS TO IMPROVE EMISSIONS, PERFORMANCE AND NOISE OF THE AUTOMOTIVE DIESEL ENGINE
Authors: Biswas Sanjoy , Mukhopadhyay Achintya
Published: September 2022

The present study aims at investigating effectiveness of the quadruple (early-pilot-main-after [epMa]) injection strategy over three different triple [early-main-after (eMa), early-pilot-main (epM) and pilot-main-after (pMa)] injection scheduling in terms of emissions, performance [brake specific fuel consumption (BSFC), torque, brake thermal efficiency (BTE) and fuel economy] and noise. The experimentation was carried out on a heavy-duty BS-IV diesel engine with 45% EGR fraction and fixed main injection (Crank-angle) scheduling at eight different RPMs and three loads of engine (20%, 60% and 100%) using design of experiments(DOE).     This comprehensive study showed that the quadruple injection strategy provides optimum results in both performance and emissions compared to the promising three triple injection strategy. The quadruple injection strategy exhibits the best BTE at all operating conditions and best BSFC at medium to high-speed zone around 0.5–1% inline to reduce combustion noise (CN) level, especially at low speeds and low to medium load of 0.2–2.2 dBA. Among triple injections, the pMa shows the best performance in BSFC, BTE, smoke and THC emissions. The epM is the best in the CO emissions and torque performance in the low-speed zone. Smoke value is marginally higher for the epMa at low to medium speed than the pMa, although average smoke emissions were the best. Taken together, the overall PM emission level was marginally better than Triple Injections, due to the impact of double pilots in combination with post-injection. In addition, NOx emissions were improved (around 3–6%) significantly with quadruple than with triple injections. The epMa injection scheduling also showed improvement in constant speed fuel economy and in pass-by-noise at the vehicle.

Authors: Safaei Babak , Chukwueloka Onyibo Emmanuel , Hurdoganoglu Dogus
Published: September 2022

The aim of this paper is to present a proposed honeycomb core shape and compare it with a normal hexagonal shape core in a sandwich beam. The sandwich cores are simulated in finite element with different materials; aluminum and epoxy-carbon with six layers are used as face sheet and the results are compared to those obtained theoretically. Simulation of 3-point bending test is performed in commercial software ANSYS to verify the analytical results with the numerical ones. Hence, for simplicity one layer of the skin is used on the equivalent model of sandwich for lesser computational time and more accurate evaluation. Simulation of harmonic analysis of hexagonal core and proposed core shape is carried out in frequency domain to identify the core with less deformation under high frequency and it can withstand harmful effects. The proposed core shape model having the same cell numbers and material as the normal hexagonal model is compared with experimental results; it is observed that the proposed core shape model has good flexural stiffness, resonance, fatigue, and stress resistance at a higher frequency.

Authors: Blegur Jusuf , Rajagukguk Christin P. M. , Rosari Renya
Published: September 2022

Physical education is a subject that requires students to perform openly in public. It seems a more critical way because it needs feedback from teachers and classmates. Many students experience a crisis in social self-esteem because of negligence in their performance. This study aims to test the determination of teacher and classmate support for students' social self-esteem. The participants were 94 junior high school students, grade 7 (M = 12.7660; SD = 0.53733). We collected the data using The Teacher and Classmate Support Scale and Social Self-Esteem Inventory. The data were analyzed descriptively and with the t-test. The results of teacher and classmate support and students’ social self-esteem variables show positive results, as well as proving that teacher and classmate support affects students' social self-esteem during physical education learning activities. The presence of teachers in the learning class is necessary to provide social, emotional, and cognitive support to students so that they become more confident in performing their abilities and also feel comfortable with every performance they produce in some learning experiences and expressive learning cultures.

Authors: Petrović-Ranđelović Marija , Jovanović Sonja , Radukić Snežana
Published: September 2022

The purpose of this study is to determine the relationship between individual dimensions of institutional quality and inflows of foreign direct investment (hereinafter: FDI) on a sample of European countries in 2020. In order to investigate this relationship, the data used are from the relevant World Bank databases. Taking into account the heterogeneity of the analyzed countries regarding the development level of the dimensions of institutional quality, cluster analysis is applied to define homogeneous groups. After identifying the significance of differences in the development level of the institutional quality dimensions between clusters, the analysis focus is placed on the group of countries that belong to the first cluster. The Gray relational analysis is applied to identify those institutional quality dimensions which development should be improved. The main empirical finding of this study reveals that the relative importance of the individual institutional quality dimensions in determining FDI inflows varies in the observed countries. Also, the analysis shows that a low level of political stability has the greatest negative impact on FDI inflows in countries that belong to the first cluster. Therefore, this study gives policy recommendation regarding the activities that should be taken by the authorities in order to create an enabling institutional environment for FDI in these countries.

Una perspectiva teológica poscolonial sobre los laicos, pastoral urbana y la teología
Authors: Olmedo Sevilla Josué , Vinolo Stéphane
Published: September 2022

Stefan Silber’s theological contributions are explored from a postcolonial viewpoint. The application of postulates to postcolonial and decolonial studies are pertinent for the Church pastoral and theological work because they facilitate a better understanding of his work and reflection about present reality. By keeping track of the German theologian Stephan Silber through a bibliographical documental methodology from his pastoral and theological reflections, his contributions are outlined from a postcolonial perspective to understand and transform theological practice in three areas: laymen role, urban pastoral, and theological work in itself. So, an invitation is made to consider the possibilities theology poses in postcolonial and decolonial clues for a continuous renovation of the Church faith and life. Silber shows that these perspectives, far from being a threat for the Church owing to their critical tone, can be allies for its change and fidelity to Gospel.

Authors: Mohammad Sameena , Devi K. Rama
Published: October 2022

Abstract: In this article, here we propose a new architecture of hardware for a high-speed finite impulse response (FIR) filter using seamless fine-grained pipelining. This proposed parallel full pipeline FIR filter can generate an output sample in a limited gate delays by fixing the pipeline registers in between components and also across the components. A precise critical path analysis at the gate level allows to create a suitable pipelining strategy depending on the throughput. This paper also presents modified full adder, based on multiplexers which establishes trade-offs in terms of area, power and delay. The advance FIR filters are incorporate to measure the balance between complexity and speed, and also maximum throughput. The effectiveness of the proposed method is synthesized and simulated using Xilinx Vivado 2018.3 along with improvement of area, delay and power consumption.

Published: October 2022

Abstract: The main background of this study is the desire to create materials through sustainable methods that will be environmentally friendly and have low-cost production. Most authors have focused on developing aluminum matrix composites through various inorganic reinforcements. These AMCs have improved mechanical, physical, chemical, and thermal properties as well as improved wear and corrosion resistance. This paper studies alternative reinforcement materials that are organic, inexpensive, and easily available which can be used in place of inorganic reinforcements. Based on the literature that has been studied, various organic reinforcements like aloe vera, coconut husk, rice husk, and so on have been used for developing aluminum matrix composites. It was discovered that the addition of organic materials as reinforcements results in improved mechanical and physical properties of the composite materials, based on the literature review.
FORMATION OF COMPUTATIONAL SCHEMES OF ADDITIONAL TARGETED CONSTRAINTS THAT REGULATE THE FREQUENCY SPECTRUM OF NATURAL OSCILLATIONS OF ELASTIC SYSTEMS WITH A FINITE NUMBER OF DEGREES OF MASS FREEDOM, THE DIRECTIONS OF MOVEMENT OF WHICH ARE PARALLEL, BUT DO NOT LIE IN THE SAME PLANE
Authors: Lyakhovich Leonid , Akimov Pavel , Mescheulov Nikita
Published: September 2022

For some elastic systems with a finite number of degrees of freedom of masses, in which the direc-tions of mass movement are parallel and lie in the same plane (for example, rods), special methods have been developed for creating additional constraints, the introduction of each of which purposefully increases the value of only one natural frequency and does not change any from the natural modes. The method of forming a matrix of additional stiffness coefficients that characterize such targeted constraint in this problem can also be applied when solving a similar problem for elastic systems with a finite number of degrees of mass freedom, in which the directions of mass movement are parallel, but do not lie in the same plane (for example, plates). At the same time, for such systems, only the requirements for the design schemes of additional targeted constraints are formulated, and not the methods for their creation. The distinctive paper is devoted to solution of corresponding sample of plate analysis with the use of approach that allows researcher to create computational schemes for additional targeted constraints for such systems.

Published: September 2022

This paper considers the real-time control of a class of complex
continuous nonlinear systems with an increasing requirement on control
accuracy and unknown dynamics at the start time due to their complex
dynamics and uncertainties. A Koopman approximate model-based adaptive
MPC design using the Lyapunov technique is explored. Specifically, the
nonlinear system is modeled/transformed into a linear model in a lifting
space with the Koopman operator. A recursive update of the approximator
is provided by which the parameters set of the approximator is in a
nested form and a shrinking of the boundary of the approximator’s
mismatch from the real system is obtained. Also, based on the Koopman
model and its mismatch boundary, a sufficient condition that ensures the
states of the nonlinear system eventually converge to a small
neighborhood of the origin is deduced. An FCCU example is employed to
show the effectiveness of the proposed control law.

Published: September 2022

The release calls carry species-specifics characteristics that can be used for the diagnosis of closely related species. Despite its importance, for the Lophyohylini tribe, this type of call is known only for two species. Corythomantis greeningi is a species widely distributed in xeric and sub-humid regions of northeastern Brazil. Herein, we describe for the first time the release call of C. greeningi recorded in the Pedro II municipality, state of Piauí, northeastern Brazil. The release call, emitted during handling in its the axillary region, was structurally and quantitatively different from the advertisement call, presenting a lower number of pulses per note and a lower dominant frequency. This work represents an important contribution to the intra and interspecific communication mechanisms of the species.

Protium is the most frequent genus of Burseraceae in the Adolpho Ducke Forest Reserve (Manaus, Amazonas), which is where its species were previously identified and mapped and this has favored various studies of this central Amazon forest. A number of P. divaricatum Engl., P. opacum Swart and P. strumosum Daly trees were selected with the objective of providing information about their chemical and biological aspects. Resin exudation was stimulated with the use of ethephon and the essential oils from the aerial parts and the resin were evaluated using GC. The occurrence of galls was also registered. The hydrocarbon sesquiterpene ß-caryophyllene was detected in high percentages in the essential oils of leaves and twigs of P. divaricatum (52.75% and 14.74%) and P. opacum (39.55% and 17.86%), respectively. The predominant oxygenated sesquiterpenes were spathulenol in the leaves (19.52%) and twigs (31.29%) of P. divaricatum, in addition to khusimone (32.36%) in the twigs of P. opacum. Monoterpenes were identified in the essential oils of the P. strumosum resin, with p-cymene (58.97%) predominating in the naturally exuded resin, limonene (61.45%) and p-cimen-8-ol (53.92%) in the resin of the first and second extraction with ethephon, respectively. On the trees, galls were identified that will help in the identification of the three species.

Published: September 2022

Heavy metal pollution is an serious environmental problem because they have toxic effects on living organisms. In recent years, the use of microbial biosorbents to remove heavy metal pollution have studied.  Many biological materials are used to remove copper ions. In this study, the biosorption capacity of lyophilized Pantoea agglomerans for Cu (II) ions were investigated under various conditions (initial pH, contact time, initial heavy metals ion concentration). The monocomponent biosorption data have been analyzed using isotherm (Freundlich and Langmuir) and kinetic models. The highest copper uptake capacity of the biomass was obtained at the initial copper concentration of 250 mgL-1 at pH 5.0 and contact time 90th minute. The equilibrium data correlated well with the Langmuir and Freundlich model. It was found that the pseudo-second-order kinetic model fitted the experimentally obtained data. Liyofilized P. agglomerans biomass appears to be an inexpensive and efficient biosorbent for the removal of Cu (II) from aqueous solutions.

OBJECTIVE

Down syndrome (DS) is the most common form of chromosomal trisomy. Genetic factors in DS may increase the risk for diabetes. This study aimed to determine whether DS is associated with an increased incidence of diabetes and the relationship with obesity across the life span compared with control patients.

RESEARCH DESIGN AND METHODS

This matched population–based cohort study analyzed UK Clinical Practice Research Datalink data from 1990 to 2020.

RESULTS

A total of 9,917 patients with DS and 38,266 control patients were analyzed. Diabetes rates were higher in patients with DS (incidence rate ratio 3.67; 95% CI 2.43–5.55; P < 0.0001) and peaked at a younger age (median age at diagnosis 38 [interquartile range 28–49] years vs. 53 [43–61] years in control patients). Incidence rates (per 1,000 person-years) for type 1 diabetes mellitus were 0.44 (95% CI 0.31–0.61) in patients with DS vs. 0.13 (0.09–0.17) in control patients. Type 2 diabetes mellitus (T2DM) rates were higher in patients with DS versus control patients in age-groups from 5 years up to 34 years. In patients with DS, peak mean BMI was higher and at a younger age (males 31.2 kg/m2 at age 31 years; females 32.1 kg/m2 at 43 years) versus control patients (males 29.5 kg/m2 at 54 years; females 29.2 kg/m2 at 51 years). Obesity was associated with an increased incidence of T2DM.

CONCLUSIONS

At younger ages, the incidence of diabetes in patients with DS is up to four times that of control patients. Peak mean BMI is higher and established earlier in DS, contributing to T2DM risk. Further investigation into the relationship between obesity and diabetes in DS is required to inform treatment and prevention measures.
Overlap welded joint strength of 2.0 GPa-strength steel sheets using single-mode laser wobbling
Authors: Kang Minjung , Kwak Yeonho , You Hyeonjeong , Kang Sanghoon , Kim Cheolhee
Published: September 2022

During laser overlap welding of high strength steels, a wide interface-bead width is a prerequisite for ensuring joint strength. However, a wide weld bead is accompanied by thermal effects such as thermal deformation and softening of the heat-affected zone owing to the high heat input during welding. Hot-press-forming steel with a strength of 2.0 GPa is the highest strength steel sheet in the automotive industry. When laser-welded, the minimum hardness in the heat-affected zone is less than 2/3 of the base metal hardness. In this study, single-mode laser and beam wobbling was employed to obtain a proper bead width while minimizing the heat input in the lap welding of steel sheets with a strength of 2.0 GPa. Two strategies—high frequency wobbling/high travel speed and low frequency wobbling/low travel speed—were evaluated with a laser power fixed at 1 kW. In the high frequency wobbling/high travel speed condition, the load-carrying at the overlap joint increased as the travel speed and wobbling frequency decreased. However, even in the case with the maximum fracture load, the fracture location in the tensile–shear test was the weld metal. The low frequency wobbling/low travel speed strategy was more effective in ensuring joint strength, and the fracture location in the tensile–shear test moved to the heat-affected zone. An equivalent tensile strength of 1 GPa or more was achieved by selecting appropriate parameters. Under optimal conditions, multiple weld penetrations and sufficient interface beads were confirmed on the cross section.

Published: September 2022

The water-assisted laser processing of carbon fiber-reinforced plastics (CFRPs) can reduce thermal damage. However, the machining quality and efficiency will be reduced by laser-induced cavitation bubbles when laser processing in the water. A method of in situ ultrasonic vibration-assisted laser processing of CFRPs in the ethanol solution was proposed to reduce the adverse effect of cavitation bubbles on machining. The influence of process parameters on machining was studied by the design of experiments. The dynamic ablation behavior of the laser-ablated area was captured in situ by a high-speed camera. The machining mechanism was analyzed. The results show that the volume of the cavitation bubble is reduced in the ethanol solution, and the laser scattering is reduced. The machining quality is improved. When the volume fraction of ethanol exceeds 40%, the laser extinction rate is increased by the accumulation of cavitation bubbles. The heat-affected zone (HAZ) and the etching depth were reduced by 57% and 25%, respectively. The ultrasonic vibration can explode the cavitation bubble, and the interference of the cavitation bubble to the laser is reduced. The effect of mechanical erosion is enhanced. The etching depth was increased by 119%. The cooling effect of the ablated area is enhanced by ultrasonic vibration. The HAZ is reduced by 57%. According to the findings of this study, the material deposition can be effectively reduced when the method of the paper is used, a clean groove is generated, the fiber pull-out is improved, and better machining quality can be obtained.

Published: September 2022

The high prevalence of cardiovascular disease in patients with chronic kidney disease indicates significant interactions between pathogenic pathways operating in the kidney and heart. These interactions involve all cell types (endothelial cells, smooth muscle cells, macrophages, and others), components of the vasculature, glomeruli, and heart that are susceptible to oxidative damage and structural alterations. A vicious cycle occurs whereby harmful factors such as reactive oxygen species and inflammation damage of vascular structures that themselves become sources of additional dangerous/toxic components released into the local environment. The evidence of this vicious cycle in chronic kidney disease should therefore lead to add other factors to both traditional and nontraditional risk factors. This review will examine the processes occurring during progressive kidney dysfunction with regard to vascular injury, renal remodeling, cardiac hypertrophy, and the transversal role of oxidative stress in the development of these complications.

It is known that the existing methods of using electromembrane systems (EMS) do not allow the most efficient water treatment and water treatment at overlimiting current modes, which is why there is a need to determine the operating parameters of electrodialysis plants to prevent complex destructive effects, it is essential limiting mass transfer, and reducing the efficiency of EMS. In addition, in practice, a contradiction is found in practice - an increase in the potential jump in the existing EMS does not provide an intensification of the transfer of salt ions under overlimiting current modes. The article is devoted to the study of the influence of one of the destructive phenomena - the breakdown of the space charge on the performance of electromembrane systems in highly diluted salt solutions. The aim of this work is a theoretical assessment of the effect of space charge breakdown on the transport of salt ions in electromembrane systems. A mathematical model based on the Nernst-Planck and Poisson equations has been developed. The process of electrodialysis desalination of a NaCl solution located in a flow chamber between an anion exchange membrane (AEM) and a cation exchange membrane (CEM) is considered. The solution flow is directed from bottom to top. Numerical modeling of the effect of space charge breakdown on EMS performance in highly dilute salt solutions has been carried out. The new mathematical model and software have been developed for numerical simulation of the effect of space charge breakdown on EMS performance in highly dilute salt solutions. In this work, using a 2D mathematical model and the formula for the current-voltage characteristic of the desalination channel, the effect of space charge breakdown on the transfer of salt ions in electromembrane systems at various values of the potential jump was determined for the first time. The ranges of currents are determined, which correspond to a high and slight increase in the performance of electromembrane systems, as well as a range of currents in which there is no increase. The obtained results can be used to determine the optimal value of the potential jump according to the criterion of maximum productivity. The results obtained can be applied to the design of industrial EMC to intensify mass transfer and increase productivity.

The work is devoted to the «neural network-lbp» method of processing satellite images of multispectral water coastal systems for identification of phytoplankton populations of spotted structure: determination of their boundaries, distribution of color gradations and, based on this, determination of the distribution of phytoplankton concentrations inside the spots and the location of the center of mass. The efficiency and effectiveness of the proposed neural network-lbp method is investigated in comparison with the method based on the use of a three-layer neural network. For the analysis, a test set of images is involved – flat shapes with rather complex boundaries, which will allow us to quantify the quality of the algorithms being compared. The results of the work show an increase in recognition accuracy by 1.5-3% when using the proposed method.
Influence of residual stress models prescribed in design codes for steel I-section behavior
Authors: Lemes Í. , Silva J. , Batelo E. , Silveira R.
Published: September 2022

Non-uniform cooling of steel cross-sections during the manufacturing process generates a state of residual stresses in the cross-section. Design codes describe the distribution of these stresses in different ways. This work aims to numerically investigate the influence of these models on the behavior of bare steel and steel-concrete composite sections by the curves: flexural stiffness-bending moment, moment-curvature and yield curves (initial and full yield). These procedures are important for the study of the simplified curves used in some methodologies of the refined plastic hinge method (RPHM) analysis. The study will use the strain compatibility method (SCM), where, if the axial strain of the cross-section point is known, the section stiffness is obtained using the tangential Young's modulus derived from the materials constitutive relationship. A fiber discretization algorithm is applied and the residual stresses are explicitly inserted into the fibers automatically. The methodology was calibrated using the moment-curvature relationship and the flexural stiffness-bending moment curve. These results were numerically stable and good convergence with literature data was obtained. In general, the residual stress model of the American standard (AISC, 2016) defines a larger elastic region within the interaction diagrams then European model (CEN, 2005). The results obtained showed that the initial yield curves for steel I-sections under minor axis bending require revision for application to RPHM, mainly due to the loss of symmetry in relation to the M axis in the normal force-bending moment (NM) interaction diagram.
