Role of mixed entropy in sintering of manganite-based perovskite oxides: Faster densification with delayed grain growth

High entropy perovskite oxides (HEPOs) have garnered significant attention due to their superior performance compared to conventional perovskite oxides. However, there is a limited understanding of the sintering behavior of HEPOs. This study aims to obtain a mechanistic understanding of how the sintering of the manganite-based perovskite oxides varies with the mixed entropy. Based on systematic sintering experiments, detailed microstructural characterization, and molecular dynamics simulations, we found that the densification process of manganite-based perovskite oxides with increasing mixed entropies follows a similar pattern to conventional perovskite oxides. The mixed entropy significantly influences the final and middle stages of densification but has negligible effects in the initial stage. More importantly, the densification becomes easier and faster with the increased mixed entropy, while the grain growth is delayed to the higher relative density and the corresponding activation energy for grain growth is also significantly enhanced. Consequently, this creates a more ideal situation for achieving denser materials with smaller grain sizes during sintering, shedding light on rational optimization of the sintering and resulting properties of high entropy perovskite oxide.

“You Have to Find a Way for This Child to Be at the Center”: Pediatric Cardiologists’ Views on Triadic Communication in Consultations on Congenital Heart Defects

ABSTRACT Congenital heart defects (CHDs) are present at birth and require ongoing management of personal, family, and medical aspects of care, including communication between family and medical staff. Effective communication is considered one of the main objectives of patient-centered care. Communication in pediatric medicine is especially challenging because it includes children and their parent(s), and children’s cognitive and communication skills are still developing. Based on the model of behavior in pediatric communication , this study focused on pediatric cardiologists’ views of the roles of children, parents, and physicians in the triadic encounter and their experiences in communicating information on pediatric CHDs in medical encounters. Semi-structured interviews were conducted with 17 experienced pediatric cardiologists and cardiac surgeons (five women and 12 men) at three medical centers in Israel. The grounded theory approach was used to identify three main categories: (1) the positioning (centrality) of the child in the setting (ideal vs. actual situation), (2) addressing parents’ emotional needs, and (3) the physician’s role as mediator between parent(s) and child. In each category, three elements are discussed: The physician’s agenda, obstacles and challenges, and the physician’s practical methods. Physicians strongly support children’s involvement in triadic encounters yet face challenges in effectively integrating them into the information exchange process during cardiology consultations. Struggling to balance the principles of patient- and family-centered care, and without clear guidelines, they rely on their personal beliefs and experiences to formulate communication strategies that address parents’ and children’s needs.

Fire resistance of concrete‐filled steel tube beam‐column under elevated temperatures and cyclic loading

AbstractThis article aims to provide an overview of the fire resistance of concrete‐filled steel tube beam columns and the importance of fire resistance in building design and construction. Ten experimental models were developed to predict the behavior of different types of concrete‐filled steel tubes and beams‐columns under Fire resistance conditions (ISO‐834) under cyclic loading in two groups. The results show the type of concrete effect on moment‐rotation characteristics. Also, increasing the length of the stiffener on the column increases the load and moment capacity, but also affects the failure mode. Moreover, the ideal situation is to use PP fiber concrete in concrete‐filled steel tube structural elements where displacement and rotation capacity are prominent. Withal, the recycling of fire‐exposed steel beam‐to‐column tube element is available by filling the inner space with C50 and/or polypropylene fiber reinforced concrete, also as a fireproof member.

Assessment of the efficiency of ozone application for post-harvest microbial disinfection of some fruits and vegetables

The treatment of ozone is widely used for post-harvest fruit and vegetable processing because of its high activity and safety. As opposed to the gaseous form, the aqueous form is more active. The technique and commodities are major factors in determining the ozone efficiency ratio. Fresh products are a source of pathogen organisms such as Fecal coliform (FC) that are considered a threat to quality and health. This study applied to evaluate the quality and safety of some fruits such (as apples and oranges) with some fruit vegetables like (tomatoes, bell peppers, eggplant, cucumber, and squash), as well as some vegetables such as (lettuce, and arugula) by detection ratio of FC microorganisms. These classes of products were exposed to (3 mg/L) aqueous ozone for 5 minutes. Overall, these concentrations improved entire products. Ozon application lowered the overall activity of contaminants about 25 times from 2792.26 to 105.96 RLU/cm2 after processing. Most of the commodities as eggplant, lettuce, apples, and orange were disinfected and other products significantly decreased. The system is capable of inactivating about 6935.3 relative light units (RLU/cm2) of FC in an ideal situation

Ultrasensitive Detection of SARS-CoV-2 Nucleocapsid Protein Based on Porphyrin-Based Metal-Organic Gels with Highly Efficient Electrochemiluminescence at Low Potential.

Metal-organic gels (MOGs) are a new type of intelligent soft material, which are bridged by metal ions and organic ligands through noncovalent interactions. In this paper, we prepared highly stable P-MOGs, using the classical organic electrochemiluminescence (ECL) luminescence meso-tetra(4-carboxyphenyl)porphine as the organic ligand and Fe3+ as the metal ion. Surprisingly, P-MOGs can stably output ECL signals at a low potential. We introduced P-MOGs into the ECL resonance energy transfer strategy (ECL-RET) and constructed a quenched ECL immunosensor for the detection of the SARS-CoV-2 nucleocapsid protein (SARS-CoV-2-N). In the ECL-RET system, P-MOGs were used as energy donors, and Au@Cu2O@Fe3O4 were selected as energy acceptors. The ultraviolet-visible spectrum of Au@Cu2O@Fe3O4 partially overlaps with the ECL spectrum of P-MOGs, which can effectively touch off the ECL-RET behavior between the donors and receptors. Under the ideal experimental situation, the linear detection range of the SARS-CoV-2-N concentration was 10 fg/mL to 100 ng/mL, and the limit of detection was 1.5 fg/mL. This work has broad application prospects for porphyrin-MOGs in ECL sensing.

Perioperative knowledge, self-efficacy and clinical practices related to postoperative delirium care in older people across geographical regions in Australia.

In older people undergoing surgery, there is a lower tolerance for complications. This highlights the need for documented clinical practices on proper prevention, pre-screening and management of complications such as postoperative delirium (POD). Evidence-based clinical practice guidelines exist for delirium management; however, the management of delirium in clinical settings differs widely. This study aims to develop an understanding of the knowledge, components of self-efficacy (confidence/competence), and clinical practice related to POD care among preoperative and recovery nurses across different types of geographical locations in Australia. A 27-item online survey was sent out to professional associations focused on perioperative care across Australia. The participants included practicing registered nurses specialising in perioperative care. The main outcome measures were Knowledge, confidence/competence and clinical practice relating to POD care in older patients. Respondents were categorised into two groups-major cities and rural and remote. Mean age was 46.3 years for respondents in Australian major cities and 49.5 for the comparison group. There was a statistically significant difference between Australian major cities and 'rural and remote' in confidence in detecting hyperactive delirium, 25.2% versus 11.7% respectively as well as managing hyperactive delirium, 13.8% versus 1.7%, respectively. Similar results were also observed on hypoactive delirium. Respondents from both groups did not mirror the ideal situation in managing a hyperactive delirium. Results from this study are inconclusive and there is no clear-cut observation in clinical practice or knowledge between the two geographical categories in this study. The absence of a distinct strategy with POD prevention highlights the need for a uniform approach and consensus on POD prevention and management in older people. This can be achieved by creating more awareness and education through professional development related to POD.

Combining fuzzy MCDM with Kano model and FMEA: a novel 3-phase MCDM method for reliable assessment

AbstractIn the circular economy era, this study addresses sustainable business management for high-investment and long-life cycle projects, where accurate and reliable assessments are crucial to ensuring successful outcomes. The objective is to elevate the reliability of assessments by introducing a novel decision-making method that, for the first time, integrates time-based satisfaction and risk factors simultaneously. We propose a 3-phase multi-criteria decision-making (MCDM) method, which combines fuzzy MCDM comprising fuzzy analytic hierarchy process and fuzzy technique for order preference by similarity to ideal situation (TOPSIS), Kano model, and failure mode and effects analysis (FMEA) techniques, to handle reliable assessments effectively. Our method is distinct in its incorporation of time-based satisfaction weights derived from Kano model, emphasising decision-makers’ criteria preferences in short, medium, and long terms. Furthermore, we introduce risk-discounted weights by using FMEA to tune criteria scores. The method is validated via a numerical example case, assessing and selecting the most appropriate hydrogen storage method for lightweight vehicles. The results suggest that cryo-compressed hydrogen tank with 250–350 bar and at cryogenic temperature is the most suitable storage method. Health & safety with a weight of 0.5318 emerges as the most important main criterion, and permeation & leakage with a weight of 0.4008 is the most important sub-criterion. To bridge the gap between theoretical research and practical application, we transform the new method into a user-friendly web application with graphical user interface (GUI). End-users can conduct reliable assessments and foster sustainable business management through informed decision-making.

Translator–Author Encounters: Two Cases of Translating from Arabic

The relationship between translators and authors in literary translation is an area that needs further inquiry. Specifically, it is essential to understand how the relationship between authors and translators influences translators’ status and, consequently, the recognition translators are granted. The objective of this study was to expand knowledge on literary translation by examining two cases of translation of Arabic novels to English. The research questions under investigation sought to understand a) the links between selected translation strategies and professional or personal histories and b) the impact of the background of translators on their collaboration with authors and, consequently, on their roles and status. A case study methodology was used to examine the translation of two Arabic novels, Sidi Wahdana and Banat AlRiyadh. Drawing on the sociology of translation, encounters between translators and authors and the impact of such encounters on the recognition attributed to the translators were examined. The findings revealed in the translation of Sidi Wahdana; the author, Alem, works closely with the translator, McDonough, to produce the English translation. Thus, McDonough became Alem’s co-author. In the translation of Banat AlRiyadh (Girls of Riyad) Alsanea, the author takes over the translation process and reshapes the English version. Thus, Alsanea becomes the first translator, and Booth is demoted to a co-translator. It is concluded that relations between an author and a translator can become complex, and translators may not get the recognition expected in an ideal situation.

The application analysis of the eco-interior concept to My Dormy Hostel UMM as an effort to achieve environmental sustainability

Public awareness about environmental sustainability is increasing. Various approaches are being taken to address environmental issues, including in the field of interior design. One of the approaches that highlight environmental awareness and sustainability is known as eco-interior. My Dormy Hostel UMM is a pioneering hostel in Malang that utilizes repurposed containers as its primary building material. This study aims to observe the application of the eco-interior concept at My Dormy Hostel UMM, with diagnostic evaluation analysis based on the concept of eco-interior. The eco-interior concept is divided into four levels of classification: ideal situation, substantial and mild effort, and general application. The finding shows that falls under the third level of the eco-interior concept, “substantial effort”. The application of the concept is commendable but not yet considered ideal or optimal. Specifically, the ventilation system meets the standards for an ideal situation, while the space organization, material selection, and lighting systems meet the criteria for a substantial effort. Electromagnetic emissions only reach the level of mild effort, whereas water sanitation, indoor pollution, and indoor waste management are categorized as general applications. This research is expected to be a reference for evaluating the application of the eco-interior concept in the hospitality industry.

Confidence Interval: Advantages, Disadvantages and the Dilemma of Interpretation

Abstract: Confidence interval (CI) is one of the important reporting tools for research data as it not only provides valuable information about the effect size along with its width but also possible clinical significance. Unfortunately, this approach is not being utilized to its fullest extent. Determining point estimate always includes an element of uncertainty due to associated sampling error. A confidence interval may be an appropriate tool to measure this uncertainty. Further, the P value does not convey information about the magnitude of an effect and the error associated with it. Thus, in an ideal situation effect size should preferably be associated with a confidence interval to assess precision. Not only does CI let us assess likely effects but also decides whether the intervention applied could have clinical utility. In contrast, the P-value limits our option to either reject any differences that are not significant or accept those that are. However, confidence intervals are commonly misinterpreted. It is imperative to understand that the CI is not the range of effects that 95% of patients in the population exhibit. Moreover, it would also be erroneous to say that there is a 95% probability that the CI includes the true population effect. Interpretation is usually based on the context in which the confidence interval is being looked at. From a utility point of view and like other statistical tools confidence interval approach does have several advantages as well as disadvantages and is far beyond being a perfect statistical tool.

Nonlinear vibration characteristics of virtual mass systems for wind turbine blade fatigue testing

Abstract. The biaxial fatigue test of wind turbine blades is helpful to shorten the test time and is more suitable for the actual operating conditions. Adding tuning masses to the blade is a common method for blade uniaxial testing at present, and its purpose is to adjust the load distribution in one direction of the blade. However, the tuning masses on the blade will affect the load distribution in the direction of the blade flap-wise and edge-wise at the same time in the biaxial test, so the concept of “virtual masses” is proposed to realize the decoupling of the load distribution in the biaxial test. Due to the limitation of the size of the virtual mass mechanism and the complex motion trajectory of the blade, the actual inertial effect provided by the virtual masses is different from the ideal situation, which will affect the resonance characteristics of the test system and the load distribution of the blade. Therefore, in order to evaluate the effect of the nonlinear effect introduced by the virtual masses on the resonance characteristics of the test system and the blade load distribution, the equivalent dynamic model of the bladed virtual mass test system was established by using the Lagrange method. Then, the nonlinear effects of blade amplitude and virtual mass installation parameters on the test system are obtained by a numerical method. Then, based on the nonlinear vibration theory, the approximate nonlinear amplitude–frequency characteristics of the test system are obtained, that is, the resonance frequency of the test system will decrease with the increase in the blade amplitude. Through the simulation analysis of two blades over 80 m in length, the applicability of the theoretical method is verified. It can be seen from the simulation results of the simulated uniaxial test that larger amplitudes of the blade and shorter connection rods will reduce the resonance frequency of the test system. When the vibration amplitude at the excitation point is the same, a lower resonance frequency results in a smaller load distribution level, that is, the area which is actually fully tested will be reduced. In the biaxial simulation test, the resonance frequency of the test system will be further reduced because the virtual masses will be affected by the coupled motion in both directions at the same time. Furthermore, the introduction of an external mechanism of the virtual mass will also cause deformation of the envelope of the blade biaxial trajectory, which will further affect the load distribution of the blade. This work explores the nonlinear influence of virtual masses on the actual fatigue test. The theoretical analysis is helpful to provide the basis and reference for the preliminary preparation work of the test organization, including adjusting the tuning mass scheme, adjusting the load distribution and selecting the appropriate excitation equipment.

Redesigning Maturity Models When Rolling Out Agile Transformations

Agile is conquering the competitive and fast-changing world. It benefits mandate that the implementation of a transformation to agile working is implemented as agile as can be. An important element of such a transformation is setting an improvement target: The first step an organization has to take to start working agile. One of the techniques for setting such a target is the use of maturity models (MMs), where maturity levels indicate the smart stops on the way to an ideal situation. This study finds that the traditional and external MM designs create a large gap between management targets and work floor reality. Therefore, a new method to create MM models has been introduced herein in an Agile setting to provide an easy-to-use yet powerful assessment tool for organizations. This model could not only reflect the uniqueness of the organization but also modify this uniqueness for the requirements of Agile transformations. The developed model is compared with the alternatives in literature, providing highly competitive performance with enhanced simplicity. It is clearly confirmed that the gap between top-down target setting and bottom-up achievement was sharply reduced when the structure of the MM was modified.

Reimagining English Language Teaching: Towards Developing a Heutagogical Framework

Education in its essential meaning should beget a civilized and socio-emotionally intelligent, competent mindset in its stakeholders. However, this seems an ideal situation which is impractical owing to several conditions and constraints that impede the implementation of holistic education. Pedagogical practices initially relied on rote learning and thereafter several reforms in educational policies asserted the importance of nurturing global competency among the learners. However, this shift from rote learning to a more self-directed learning is a challenging transformation which is idealized to a great extent. In this article, we argue that a sudden shift may not be possible, and to realize learner autonomy and their self-directedness, there should be a gradual but steady progress from pedagogy to andragogy and then to heutagogy. Self-directedness and learner-centredness are the crucial aspects of heutagogy. Taking examples from a case study that we conducted with teachers of English from select higher education institutions in India, we analysed the various tenets of heutagogy and its practicality in the Indian context. We investigated how teachers are incorporating aspects of heutagogy in their English classrooms and what major challenges are encountered. Their individual classroom episodes may serve as an initial reservoir of ideas to orient further research in the field. The possibility of embedding the PAH continuum in classrooms is analysed through the lens of socio-constructivist theory. The insights from this study will be valuable for teachers and students who wish to gain a deeper insight into the heutagogical learning paradigm and its integration into language teaching in the classroom.

Impact of Capital Market Development on Industrial Sector Output in Nigeria: 1986-2022

The ideal situation for any growing economy, especially one as diversely poised as Nigeria, is to have a thriving industrial sector. This sector is traditionally seen as an indispensable engine of growth, a crucial antidote to the challenges of unemployment, and a potent creator of wealth. Regrettably, the current state of the manufacturing sector in Nigeria falls significantly short of this ideal. Recent statistics indicate that the industrial sector’s contribution to GDP remains suboptimal, with the National Bureau of Statistics (NBS) reporting a decline in industrial growth despite several policy measures aimed at enhancing its growth. This research sought to investigate the impact of capital market development on the growth of industrial sector in Nigeria between 1986 and 2022 with the aid of ARDL estimation technique. The findings revealed that Stock Market Capitalization had a significant and positive impact on industrial sector growth, suggesting that as market capitalization increased, the industrial sector flourished. In the same vein, Turnover Ratio, which is the value of traded shares divided by market capitalization, was found to enhance industrial sector growth positively and significantly. These positive relationships underscored the pivotal role the capital market plays in boosting the industrial sector by mobilizing and channeling resources efficiently. However, the All-Share Index exhibited a negative relationship with the industrial sector growth, indicating that while general market sentiment might be positive, it might not always translate to growth in the industrial sector. Based on these findings, the paper recommended promoting public listings and private investments as a strategy to enhance the growth potential of the industrial sector. Furthermore, improving trading platforms, ensuring market transparency, and reducing transactional costs were emphasized to leverage the benefits of a high turnover ratio. For the negative aspects found with All-Share Index, policymakers were advised to address these components to ensure holistic development of both the capital market and the industrial sector.

Quantum State Reconstruction Through Online Shadow Tomography: Theoretical Framework and Simulation Results

The purpose of this research work is to learn the quantum states in an ideal environments analytically, computationally, and graphically. The analysis starts with the learning of quantum states in identity channels with the help of the Regularized Follow the Leader (RFTL) algorithm. Our machine will try to learn the states based on the previous information, which is called the online learning model. The objective of this problem is to minimize regret by utilizing a learning algorithm that successively anticipates quantum states through observed measurements and losses. We have to produce many copies of quantum state ρ to perform analysis on them, which indicates the use of the shadow tomography approach in an ideal situation. Our goal is to learn the shadow of the state ρ by using a series of measurement operators that have two outcomes in nature. Aaronson et al. [1] developed an online setting for a non-realizable case, where the maximum possible loss is O( √ Tn) for the best possible state up to T−measurements . It is noteworthy that this outcome is an extension of the Aaronson PAC-like findings [2]. GANIT J. Bangladesh Math. Soc. 43.1 (2023) 65-74

Peran Pemerintah Dalam Meningkatkan Volume Ekspor Kopi

Indonesia is one of the largest coffee producers in the world. Of course, it has great potential to increase the performance and volume of coffee exports globally. Given that Indonesia has become one of the largest coffee producers in the world, the development of coffee production must be carried out carefully and consistently. This research is focused on discussing what efforts the government has made in increasing coffee exports to the global market and the influence of farmers in increasing the volume of coffee exports themselves. So that later it can compete with other coffee-producing countries. The development of the coffee commodity industry is an ideal situation because Indonesia has abundant natural resources and a supportive archaeological environment. This requires government participation in improving the performance of national coffee production. From the results of this study, it is known that the government continues to strive to maximize the volume of coffee exports so that it continues to increase to the world market. The government conducts coaching to farmers, markets to the global market and improves the quality and productivity of coffee.

Self-Referral and Its Predictors Among Patients Accessing Healthcare Services in A Tertiary Hospital, In Calabar, Cross River State, Nigeria

Classified as self and non-self-referrals, the ideal situation is that patients begin from lower levels of healthcare to higher levels. This improves the utilization of the primary care units, reduces unnecessary congestion of higher levels and makes for efficient healthcare delivery in general. This study aimed to assess the prevalence and predictors of self-referral among patients accessing healthcare in a tertiary hospital in Calabar, Nigeria. Ethical approval and informed consent were obtained. The study adopted quantitative data collection methods. This facility-based, cross-sectional study was carried out among 400 patients aged 18 years and above accessing care in the General Outpatient Clinic of the University of Calabar Teaching Hospital, Calabar in Cross River State. Overall, 191(47.8%) were males while 209(52.3%) were females. The mean age of study participants was 40.5±13.4 years, the most common age group was 31 to 40 years (28.2%). Prevalence of self-referral was 68.3%. Factors significantly associated with self-referral practices were sex (p<0.001), age group (p<0.001), marital status (p<0.001) and occupation (p=0.006). At multivariate regression analysis, females compared with males (OR: 5.299; 95% CI: 3.271 to 8.587), as well as those who were presently unmarried compared with those presently married (OR: 1.920; 95% CI: 1.052 to 3.505) were significantly more likely to practice self-referral. Self-referral practice is common and sex and marital status were identified as predictors. This is more so with unmarried females. Interventions to promote utilization and referral by healthcare providers through the prescribed channel is strongly recommended. Keywords: Self- referral, Prevalence, Predictors, Healthcare, tertiary, Practice.

Використання моделі балістичного маятника в аналізі перехідних процесів кранових систем

A number of factors affecting the accuracy of experimental determination of small velocities of pendulum vibrations of the load on the rope of the crane hoisting mechanism, arising at start-up, braking or reversing of the crane system, have been analyzed. The rope is considered as an elastic thread. The influence of finite mass and bending elasticity of the viscus on the frequency of natural oscillations of the pendulum is theoretically analyzed. It is shown that the main factor influencing the natural frequency is the bending elasticity of the viscus thread, and the influence of the mass of the thread (rope) of the ballistic pendulum can be minimized. An exact analytical expression for the natural frequency of a real pendulum at arbitrary stiffness of the lightweight viscus is obtained. For small mass of cargo and speed of movement at impulse influence on the crane system (starting, braking, reversing) there are certain difficulties in taking into account the final mass and stiffness of the viscus for calculation of natural frequency of pendulum oscillations. In an ideal situation, the mass of the temple can be made too small compared to the mass of the pendulum (load and rope), but with a short length of rope increases the natural frequency of the pendulum, which reduces the sensitivity of the system to external impulsive influences, and increases the influence of the elasticity of the thread (rope) on this frequency. Therefore, in a real situation, the mass of the pendulum, its length (of the rope) and the stiffness of the temple should always be chosen and taken into account in accurate studies (and calculations) based on compromise considerations. In this study, the degree of influence of the above factors on the natural frequency of oscillation of a pendulum (i.e., essentially a weight on a rope) is theoretically evaluated in the small-parameter approximation. The results obtained in this study can be further used to refine and improve the existing engineering methods of calculation and analysis of transients (start-up, braking, reversing, etc.) of crane systems both at the stages of their design and in the modes of real operation to optimize the performance of the above systems (and mechanisms).

TRAINING AND DEVELOPMENT OF EMPLOYEES AS HUMAN RESOURCE MANAGEMENT ACTIVITIES USING THE EXAMPLE OF COMPANY “GORENJE” LLC BELGRADE

This paper focuses on the human resource management function and employee training, representing the organization's strategic effort to enhance employees' performance in their workplace. The emphasis is particularly on research regarding training and development in the company "Gorenje LLC Belgrade." Traditionally, employee training has been seen as a tool to teach employees specific skills and behaviors necessary for performing the job at a standard level of performance. However, in modern organizations, the focus of training is shifting towards aligning it with business needs and using it as a tool for knowledge creation and sharing. Employee development has become an increasingly significant activity within the human resource management function due to the globalization of the world economy, the growing need for leadership, the increasing importance of knowledge, the need to attract talented individuals, a stronger focus on quality, and rapid changes. Effective training must have clearly defined objectives, align with identified needs, be planned, and ensure the application of learning experiences. The ideal situation is when training meets both the organization's needs and the individual needs of employees. The goal of training is to eliminate any performance deficits on the employees' side in a short period.

Evaluation of radiation damage exposure for low alloy steel in J-9 irradiation channel of Argonauta reactor

The operation of nuclear facilities must satisfy the nuclear safety requirements. An analysis of the components of these facilities focuses on the structural materials. In this scenario, several types of alloys are employed in their construction. The nuclear fuel burn-up will result in damage caused by ionizing radiation. Due to continuous operation, radiation damage will build up and may result in the manifestation of macroscopic radiation effects. Such effects may change the mechanical, physical and chemical properties of structural alloys. Thus, it is verified the importance of the material behavior predictability to avoid reduction in performance or failure in these types of facilities. In order to study these effects, it’s necessary to calculate the displacement per atom (dpa) in the material. This calculation was estimated for the reactor Argonauta’s irradiation channel J-9 for low alloy steel. An ideal situation with a harder neutron spectrum was calculated to analyze the results. The dpa rate calculated in that facility was attributed to the low neutron energy fluence.
