Insufficiently high doping in polysilicon gates of metal oxide semiconductor field effect transistor (MOSFET) becomes unavoidable due to the demands for low-energy ion implantation and limited annealing conditions to achieve ultra-shallow source and drain junctions. This results in the poly-depletion effect for ultra-thin MOSFET, loss of current drive and shift in the threshold voltage. This problem gets intense when the device is further scaled down for the gate length and thickness of gate oxide. Hence, our current work focuses on the effect of gate geometrical effect and polysilicon gate doping on scaled n-channel MOSFET(NMOS) performance. The NMOS device was constructed using TCAD ATLAS tools from SILVACO software. Six different gate lengths of 0.6 μm, 0.4 μm, 0.2 μm, 60 nm, 40 nm and 20 nm were set, and the n-type doping concentration in the polysilicon gate was varied to 1× 1018, 1× 1020 and 1 × 1021 cm-3 respectively to see their effect on the NMOS I-V and C-V performances. The findings showed that as the gate length is scaled down, the drain current increases, and as the concentration of the polysilicon doping increases, the value of the threshold voltage, VTH decreases. Based on the simulation and data collected, it can be concluded that the optimum concentration of polysilicon doping that can reduce the poly-depletion effect is 1 × 1021 cm-3, and the optimum gate length that can be used to overcome the problem is 20 nm.

Use of a barrier membrane to repair congenital hard palate defects and to close oronasal fistulae remaining after cleft palate repair: seven dogs (2019–2022)
Authors: Castejón-González Ana C. , Reiter Alexander M.
Published: October 2023

OBJECTIVE

To describe the use of a barrier membrane in dogs for repair of congenital hard palate defects and closure of oronasal fistulae (ONF) remaining after previous cleft palate (CFP) repair.

ANIMALS

7 client-owned dogs.

METHODS

The hard palate defect was closed with medially positioned flaps (Von Langenbeck technique) or pedicle flaps (2-flap palatoplasty) and a membrane composed of autologous auricular cartilage from the pinna or allogenous fascia lata underlying the mucoperiosteal flaps.

RESULTS

All palate defects were considered to have a high risk of dehiscence based on their type and size and the characteristics of the surrounding tissue. The barrier membrane was used in 5 dogs for repair of congenital hard palate defects and in 2 dogs for closure of ONF remaining after previous CFP repair. Resolution of clinical signs occurred in all cases. Complete success (ie, complete closure of the palate defect and absence of clinical signs) was achieved in 5 dogs (4 with congenital hard palate defects and 1 with an ONF remaining after previous CFP repair). The persistent ONF in 1 dog with functional success (incomplete closure, but no clinical signs) was smaller than prior to surgery.

CLINICAL RELEVANCE

Barrier membranes underlying mucoperiosteal flaps may constitute an alternative technique in dogs for repair of congenital hard palate defects and closure of ONF remaining after previous CFP repair.
Entropy-Based Waspas approach for financial performance in the COVID-19 era: Evidence from Islamic countries
Authors: Erdogan Hilal H.
Published: October 2023

The purpose of this study is to compare financial performance of the Islamic banks in the COVID-19 Era. The performance evaluation was conducted on seven Islamic countries between 2017 and 2021. Entropy Method was utilized to choose the best performance evaluation criteria affecting the Islamic banks’ performance and Waspas Method was used to determine the best performing Islamic country. The results indicate that ‘liquid assets to short-term liabilities’ is the best performance criteria for Islamic banks during the ‘whole period’, ‘no pandemic period’ and ‘pandemic period’. Additionally, while the Islamic country with the best performance was Bangladesh during ‘no pandemic period’, Turkey was the leading Islamic country for both ‘whole period’ and ‘pandemic period’.
Polish household default risk and physical risk of climate change
Authors: Kurowski Łukasz , Sokal Katarzyna
Published: October 2023

This paper aims to assess the level of credit risk (from the perspective of default risk) among Polish households associated with the physical risks of climate change. In order to determine the potential impact of the physical risk of climate change on household credit risk, we conducted CAWI interviews with 1,006 borrowers residing in different Polish voivodeships (to account for heterogeneity of credit exposures to extreme weather events). According to these respondents, wildfires and storms in Poland are the greatest source of physical risk of climate change. In the event of a wildfire or storm, approximately 13% of borrowers would not be able to repay their loans while not being insured, which potentially increases banks’ credit risk and exposes banks to losses. However, we find that households underestimate the credit risk that could arise from a drought.
A comparison of tournament systems for the men’s World Handball Championship
Authors: Donoghue Peter O’ , Kristjánsdóttir Hafrún , Halldórsson Kristján , Þorgeirsson Sveinn
Published: October 2023

The men’s Handball World Championship commences with eight round robin groups of four teams before the “main round” of four groups of six teams. These groups of six each include the top three teams from pairs of initial groups. The tournament draw uses pots of eight which risks two teams in the top four appearing in the same group of the main round. A further issue is that teams finishing between third and sixth in the main round groups are awarded tournament places between ninth and 24th without any further matches. Therefore, the purpose of this investigation was to compare the current tournament system with alternatives using pots of four teams in the draw, and / or adding a knockout stage to place teams from ninth to 24th. These four tournament systems were simulated 100,000 times, using underlying regression models for the goals scored based on their World ranking points. Introducing pots of four increased the chance of reaching the quarter-finals for teams ranked one to four and nine to 12 by 1.3% and 1.6% respectively. It is recommended that the draw uses pots of four teams associated with pairs of initial groups that lead to common main draw groups.
Geography of migration motives: Matching migration motives with socioeconomic data
Authors: Baláž Vladimír , Lichner Ivan , Jeck Tomáš
Published: October 2023

Motives behind internal migration reported by internal migrants often differ from those assumed by standard economic and social theories. This research aims to narrow the gap between the stated motives and those suggested by human capital models. It relates the net migration rates by specific motives to socioeconomic and sociodemographic variables at the LAU 1 level in the period 1997–2021 in Slovakia. This research establishes that most of the stated motives behind internal migration (housing and family) differ from those assumed by human capital theories. This finding is valid for motives stated at the proximal level. The analysis of migration rates and housing supply indicates a substantial concentration of interdistrict migrants in suburban districts of affluent metropolitan regions. This finding resonates with assumptions on the latent importance of employment and income for internal migration.
Examining voter turnout using multiscale geographically weighted regression: The case of Slovakia
Authors: Kevický Dominik , Suchánek Jonáš
Published: October 2023

Voter turnout is an essential aspect of elections and often reflects the attitude of a country’s population towards democracy and politics. Therefore, examining the distribution of voter turnout and determining the factors that influence whether or not people will vote is crucial. This study aims to find significant factors that underlie the different levels of electoral participation across regions in Slovakia during the 2020 parliamentary elections. In this interpretation, special attention is paid to the ability of the main theories of voter turnout to explain the behaviour of Slovak voters. The primary analytical tool is multiscale geographically weighted regression, which represents an advanced local regression modelling variant. The results indicate that the multiscale geographically weighted regression is superior to the global ordinary least square model in virtually all aspects. Voter turnout is generally higher in economically and socially prosperous localities and regions, which is in line with the societal modernisation theory. Additionally, factors connected to mobilisation theory and the concept of ‘left behind places’ also proved to be valuable. However, in other cases, such as with the share of retirees and potential habitual voting, the outcomes were not overly convincing, and further research is required.
Effect of carbon fiber surface treatment with HNO3 and KOH on the interfacial bonding of PMMA resin composite
Authors: Jian Li
Published: October 2023

This work studied the surface, interface state and physicochemical properties of HNO3-treated and KOH-treated carbon fiber. Poly(methyl methacrylate) (PMMA) composites were prepared by the autoclave molding process using surface-treated carbon fiber as reinforcements. The physical and chemical states of the carbon fiber surfaces and the micro-interface properties and interlaminar shear properties of the composites were studied. The results show that the surface of the HNO3-treated carbon fiber has more groove structure and higher surface roughness and thus forms a better physical bond with the resin matrix. Although the oxygen-containing functional groups of the two carbon fibers are equivalent, the surface oxygen of the HNO3-treated carbon fiber is relatively high, which is beneficial to form a better chemical bond with the matrix resin, and the interfacial shear strength is about 14% higher than that of the KOH-treated carbon fiber composite.

Various Convexities and Some Relevant Properties of Consumer Preference Relations
Authors: Forrest Jeffrey Yi-Lin , Tiglioglu Tufan , Liu Yong , Mong Donald , Cardin Marta
Published: October 2023

The concept of convexity plays an important role in the study of economics and consumer theory. For the most part, such studies have been conducted on the assumption that consumer preferences are a binary relation that is complete, reflexive and transitive on the set X of consumption choices. However, each consumer is a biological being with multidimensional physiological needs so that possible consumptions from different dimensions cannot be compared by using preferences. By removing that unrealistic assumption, this paper examines how the various concepts of convex preferences and relevant properties can be re-established. We derive a series of 10 formal propositions and construct 6 examples to show that (a) a weighted combination of two possible consumptions is not necessarily comparable with any of the consumptions; (b) not every convergent sequence of a consumer’s preferred consumptions asymptotically preserves that consumer’s preference preordering; (c) not all preferences satisfy either positive multiplicativity or additive conservation; (d) three types of preference convexities – weak convexity, convexity and strong convexity – can all be introduced into general convex spaces. This paper concludes with some research topics of expected significance for future works.

Published: October 2023

This study focused on how interlanguage pragmatics (ILP) is manifested in a multicultural environment. Learners’ ability to make requests has received considerable attention in ILP research because requests are intrinsic face-threatening acts. The question this study aimed to address was to what extent a culture has an impact on the direct and indirect level of request strategies. The data were collected from thirty participants (fifteen males and fifteen females) representing five nationalities (Russian, Indonesian, Pakistani, Jordanian, and Hungarian) and studying at the University of Pannonia. The Discourse Completion Test (DCT) developed by Hendriks (2002) was used as an instrument, containing different situations to which the participants had to respond. The linguistic and cultural background of the participants was identified using an online tool, namely the Language History Questionnaire. The participants’ responses were then recorded and transcribed. The direct and indirect levels of the requests were analyzed by categorizing the head act and the internal (syntactic and lexical) and external modifiers. The data showed that the participants generally used more indirect strategies in making requests (86.2% indirect, 13.8% direct), especially those from Indonesia. Participants from Pakistan were the most direct in making requests. Moreover, they used more external modifiers than other participants to compensate for their directness.

Published: October 2023

Utilising technologies to enable language learners to accept authentic and communicative assignments is proliferating, but its effect on their self-directed language learning (SDLL) needs to be investigated. To this end, the present study aimed to investigate English for specific purpose (ESP) learners’ views on using technology-enhanced task-based language teaching (TBLT) toward their self-directed language learning. A mixed-method approach with a sequential explanatory design with 103 nursing students as research participants. This study used two research instruments: the Likert scale and an open-ended questionnaire. Descriptive statistics, Path analysis, and thematic analysis were employed to analyse the data. The findings from quantitative data revealed that students’ learning needs and utilising skills of SDLL categories have a strong influence on English mastery after receiving technology-enhanced TBLT. Consequently, ESP students must also improve process planning and use skills. They should be encouraged to schedule more consistent English lessons in and out of class. Meanwhile, the qualitative data disclose that technology-enhanced TBLT assists the learners in improving their language learning, i.e., planning process, completing tasks, and internal attributions. ESP students expressed their concerns and reported some challenges in applying language skills during speaking activities. This study implies that ESP lecturers can adopt various ways to assist ESP students in mastering English language goals through technology-enhanced TBLT.
Abraham Maslow’s hierarchical needs in No Friend but the Mountains: Writing from Manus Prison by Behrouz Boochani
Authors: Mustafa Goran Omar , Ahmad Hedayat Muhammad , Ghafor Omar Fouad
Published: October 2023

The paper attempted to analyze the character of Boochani in his memoir No Friend but the Mountains: Writing from Manus Prison, in the light of Abraham Maslow’s Theory of Hierarchical Needs. Boochani wrote his novel while he was still locked in the Manus Island detention center. It narrates the story of a man who followed his dream to reach his dreamland.  The study was carried out using a descriptive qualitative research methodology through textual analysis design. Since the study was text-based, a meticulous reading process of the text was done. We used the text as the primary source for data collection. Therefore, a portion of the sentences, paragraphs, and phrases related to the study’s objective were taken as examples and excerpts and analyzed using Abraham Maslow’s hierarchy of needs. The results revealed that Boochani, like all humans, was driven by physiological and psychological needs, ranging from the most fundamental to the most extreme. His journey aimed to get self-actualization but never could get it and hardly fulfilled other basic needs completely. Boochani’s voyage is depicted as a series of rising and falling waves. He occasionally satisfies some needs, but he never succeeds in meeting the need for self-actualization and self-esteem. And hardly does he fulfill the other three levels of the hierarchy of needs. His entire story serves as a metaphor for everyone who strives for self-actualization yet encounters obstacles.
Indonesian English learners’ attitudes towards cheating, absenteeism, and gender: Interactions with L2 achievement
Authors: Subekti Adaninggar Septi , Triyono Sulis , Pranowo Dwiyanto Djoko
Published: October 2023

The present study was conducted to find out Indonesian English as a Second/Foreign Language (L2) learners' attitudes towards cheating (AtC) in online English classes, as well as the possible influence of the combination of three variables, which are their AtC, absenteeism, and gender, on their L2 achievement as measured with their final grades. The study employed a survey method and was conducted by distributing an online questionnaire. In total, 164 Indonesian learners from various non-English departments at a university in Java participated in the study. Through descriptive statistics, it was found that generally learners reported their negative AtC in English class, suggesting disapproval towards cheating. Through multiple regression analysis, the study further found that the combination of learners’ AtC, absenteeism, and gender significantly influenced their L2 achievement, and the overall model could predict 34.5% of the total variance in L2 achievement. However, based on the beta coefficient of the three variables, only learners’ absenteeism and gender significantly affected their L2 achievement. As learners had higher absenteeism, they obtained lower L2 achievement. From a t-test analysis, female learners were found to have significantly better L2 achievement than their male counterparts. While the findings on the influence of absenteeism on L2 achievement generally conformed to literature in the field, the findings on the influence of AtC and gender on L2 achievement may suggest that further explorations may be necessary.
Challenges in reading English academic texts for non-English major students of an Indonesian university
Authors: Dardjito Hanandyo , Rolls Nicola , Setiawan Ari , Sumekto Didik Rinan
Published: October 2023

This study examines the barriers to reading academic texts among university students for whom English is a foreign language. While many previous studies have focused on instructional design for building academic reading skills, this study focuses on the fundamental issues that need consideration before setting up the instructional design for English academic reading. Taking an interpretive phenomenological viewpoint, this study applied a qualitative method through an online survey and interviews. Due to the Covid-19 pandemic, online data collection was the most accessible means of approaching the students. Ninety-five students from various non-English study programs (courses) at a private university voluntarily responded to the open-ended online questionnaire, providing survey data. Five students provided further data through individual interviews on their academic reading challenges. A thematic analysis of the survey data revealed four themes and eight subthemes representing the students’ challenges, which were explored further in the interviews. These challenges and the relationships among them are discussed. The results suggest that most students depended on single-word meanings as their prime strategy for achieving comprehension. However, this strategy also represented the most notable challenge in their effective reading of English academic texts. They failed to comprehend the text effectively because their translation did not make sense. Furthermore, the nature of the reading strategies of the student cohort had an impact on their baseline reading proficiency.
Augmenting the quality of Acehnese knowledge-based EFL material through a 4D model
Authors: Usman Jarjani , Ibrahim Lukman
Published: October 2023

Integrating local knowledge into English learning material is crucial in this globalized era as it has multiple functions, such as building students’ identity, motivating them to learn, making them attached to their culture, and preserving their local knowledge. Anchored by the curriculum theory, this study systemically developed an Acehnese Islamic cultural knowledge-based lesson material for learning English by students at senior high school and analyzed its quality based on the curriculum perspective. In doing so, this study involved EFL teachers using Tiagarajan’s 4D (Define-Design-Develop-Disseminate) model for developing the English learning material as a supplementary material for senior high schools. Local knowledge, such as Molod Nabi, Meuleumak, and Toroyong, was selected to be its content. Its quality was then assessed based on the quality criteria of a curriculum product, such as validity and practicality. The results revealed that the Acehnese local culture knowledge-based EFL lesson material for senior high schools is valid based on the teachers’ perceptions. It contains state-of-the-art knowledge and is practical for teaching English to foster the deradical characters of senior high school students. In conclusion, using the 4D model in collaboratively developing the local knowledge-based EFL English lesson material is beneficial for producing high-quality curriculum products.

Published: October 2023

Fostering students’ critical thinking (CT) is an increasing concern in EFL classrooms in China as many students struggle to utilize the skill, particularly in EFL reading comprehension classes. This study investigated the effects of graphic organizers (GOs) on 60 Chinese senior high school students’ CT skills (analyzing and generalizing) in EFL reading classes. This study adopted a quasi-experimental mixed-method research design involving an experiment and an interview. The findings of this study showed the positive impacts of GOs on students’ CT skills. After the intervention, the results of the experimental group improved significantly. The findings showed that GOs could effectively improve the analytical and generalization skills of Chinese high school English reading class students. The students in the experimental group reported that the instructions received were motivating, increased their comprehension, made them more focused on reading and aware of CT skills and how to apply them in real reading contexts. This study implies that teachers may consider GOs an alternative teaching tool to improve CT skills in English Language reading classes, particularly in EFL contexts. Guidelines for teachers to use the different types of GOs to promote critical thinking should also be prepared to ensure the effective use of GOs in promoting reading comprehension and critical thinking skills.
Variations in the use of personal pronoun agreement in Acehnese: A sociolinguistic approach
Authors: Armia Armia , Iskandar Denni , Zuriana Cut , Nurrahmah Nurrahmah
Published: October 2023

This study aims to identify variations in the use of personal pronoun agreements in the Acehnese language based on a sociolinguistic approach, by focusing on the North Aceh dialect. A descriptive-qualitative method was used and data were collected through interviews. These interviews were recorded, transcribed, and analyzed using the sociolinguistic approach by structure and semantics. The results of the study showed that the personal pronouns of the Acehnese language are influenced by social factors such as age, social status, and familiarity. In the context of the age factor, there are variations in the use of personal pronoun agreements related to communication patterns between the younger and older generations. In social interactions with differences in social status, the use of personal pronoun agreements that reflect respect and recognition of social status is more dominant. Meanwhile, in familiarity, the use of more formal or informal personal pronouns depends on the degree of familiarity between the speakers. Overall, variations in the use of agreement personal pronouns in the Acehnese language are influenced by sociolinguistic factors that reflect social dynamics, cultural norms, and relationships between individuals. Understanding these variations can provide better insight into social interactions, social hierarchies, and familiarity norms in Acehnese society.

Method: qualitative research of inductive model was conducted with semi-structured interviews and submitted to content analysis for study.
 
Results and conclusion: in the analysis were found factors indicative of the effects of neoliberalism both in the material reality of work and in the subjectivity of domestic workers
 
Implications of research: the research offers new scientific contributions to the theme of domestic work, offering theoretical bases for interventions and public policies that impact this class of workers.
 
Originality/value: the theme of the research demonstrates high social relevance for a greater political understanding of the socioeconomic scenario around domestic workers and their apprehension for future scientific and public policy works.
RPER Software - A Social Management Tool for Rapid Participatory Emancipatory Research: Planning, Design and Implementation
Authors: Felizardo Luiz Flávio , Wallau Marcelo Osório , Pereira José Roberto
Published: October 2023

Theoretical framework: This study is grounded in Social Management, a paradigm that focuses on society's deliberative process for public decisions. It also employs the Rapid Participatory and Emancipatory Research (RPER) method, an adaptation of rapid and participatory appraisals, to apply social management in rural contexts.
 
Research objectives: Identify the requirements, plan, design, assess the complexity, and implement a system to support the RPER application.
 
Methodology: The waterfall model for software development lifecycle was used to carry out the system's planning. The discipline of Business Process Management (BPM) was necessary for the requirements mapping and the Function Point Analysis (FPA) technique to measure the software complexity from a user perspective.
 
Results: The RPER application process was fully mapped, and several features that could be implemented for the software were uncovered. These functionalities address practically all the steps involved in the method’s application. In addition, the software measurement was completed, and 542 function points were found. After this, the design for the graphical user interface was then created. Finally, the software was developed using technologies such as Express for building the back-end RESTful API with Node.js, React library to create the front-end’s componentized user interface, TypeScript as the main programming language and PostgreSQL as the relational database.
 
Originality: It is notable that some software has already been used to try and promote social participation in public matters. However, studies specific to the use of information and communication technology (ICT) to resolve social issues, and, at the same time, dealing specifically with participatory techniques are non-existent. There is an overflow of software tools designed to support quantitative research in the agriculture field, yet there remains a notable deficiency in software tailored to assist qualitative research and practices.
 
Theoretical and practical contributions: The use of a web system on participatory approaches can bring advantages. In the theoretical side, this research might provide insights into these methods’ evolution. It will also provide a foundational framework for understanding the intersection of ICT and participatory techniques, paving the way for future research in this area. Some other more practical benefits include the wider distribution and dissemination of results, data transparency, the unification or centralization of the research made using the methods, the organization of data, the possibility of automation on report generation, better communication and collaboration between team members, and data safety with periodic backups. Nonetheless, the software could serve as a platform for preparing new researchers with help and tips section for each of the methods’ techniques.

Published: October 2023

Objective: To assess the knowledge and the perceptions of acne among adolescents. Methods: Cross-sectional study, carried out from May 2018 to May 2019. Data were collected through a questionnaire administered to students aged 13 to 20 years enrolled in two schools, with 793 participants (462 from a public school and 331 from a private school). Data were evaluated by Pearsons chi-square test, Yates test and Students t tests. Results: The mean age was 15.02±1.25 years in the private school, and 16.21±1.45 years (p=0.07) in the public school. In the private school, 75.8% of adolescents had acne, against 79.6% from the public (p=0.08). In the private school, 54.7% consulted a doctor due to acne, against 45.8% in the public school (p <0.0001). More public-school students did not think it was necessary to see a doctor for acne than in the private school (67.8% vs 32.2% - p<0.0001). More public-school students responded that mites cause acne. The perception that hormonal contraceptives worsened acne was present in 42% of the students from the public school and in 28.4% from the private (p<0.001). Conclusions: Adolescents had incorrect perceptions about acne, especially those from public schools, who also had less access to medical care.

Heuristic and functional aspects of nomination (case-study of English anthroponymic sobriquet formations)
Authors: Vishnyakova E.A. , Vishnyakova O.D. , Sergienko P.I.
Published: October 2023

The article deals with functional and heuristic features of anthroponymic sobriquets in such English discourse varieties as literary discursive space, political discourse, Public Relations-discourse. Anthroponymic sobriquets represent themselves as the units of secondary nomination and linguistic manifestations of evaluative process, in which certain attitudes of linguocultural surroundings are formed and expressed. While being represented in discourse the units under analysis fulfill such basic functions as identification and evaluation, based on individual subjective characteristics that in the course of time acquire the more general character and to a certain extent tend to become possession of the linguistic cultural community. Being part of the discursive space anthroponymic sobriquets may acquire peculiar characteristics determined by communicative-pragmatic features of corresponding texts and communicative situations in question. In terms of their functional and heuristic perspectives anthroponymic nicknames serve to be the result of optimization with respect to linguistic means and intellectual effort saving, which refers to the semantic and structural peculiarities of the units under analysis, which can be regarded as both linguistic signs and signs-indexes performing discursive functions.
Graffiti and new media: Levearaging technology to advance creativity and learning in Nigeria
Authors: Okon Patrick Edem , Udoyo Okon Effiong , Ojorgu Leonard Odum
Published: October 2023

The paper explored the relationship between graffiti and new media, with specific focus on the effect of new media appropriation on the growth of graffiti writing in Nigeria. Qualitative research design and methodologies were used. The theory of technological determinism provided the conceptual directions. Findings showed that graffiti artists were increasingly active on social media; and, used social media for different purposes, including graffiti-based artistic activities. While a wide range of social media were used, only Instagram was the most preferred, because of its unique technical qualities. The engagements of graffiti artists with new media were, in varying ways, bearing innovative and socio-cultural benefits. Apart from providing opportunities for the showcasing of talents or the digital documentation of graffiti, the interface had also allowed for improved artistic creativity, through the placements of graffiti arts unto virtual spaces as Non-Fundable Token Arts (NFTs), as well as the education of young adults online/offline on graffiti arts. Also, in order to mitigate the low status of public awareness on graffiti in Nigeria, graffiti artists should heighten their engagements with social media to popularize the practice in its contextual form; and, the placements of graffiti arts on NFT panels should be seen as a step in the right direction, towards the preservation of graffiti arts for posterity.
Validity of One-Dimensional Radiative Transfer in Participating Media
Authors: Yuen Walter W.
Published: October 2023

For radiative transfer through an absorbing, scattering medium with planar geometry, the validity of the one-dimensional assumption is examined. Using the generalized zonal with Monte Carlo method as a solver, exact numerical solutions are generated to identify conditions under which the one-dimensional assumption is valid. Specifically, for the predictions of transmissivity and reflectivity for a collimated or diffuse energy beam through a planar slab, numerical data are presented to show that a medium aspect ratio (ratio of the width to the thickness) of five or more is a necessary but not sufficient condition for the data to agree with the one-dimensional result. The implication of this condition on the utilization of the one-dimensional radiative transfer assumption in some practical engineering problems such as pipe flow and thermal insulation is discussed.
