Influence of sintering temperature on structure and mechanical properties of polycrystalline cubic boron nitride composites
Authors: Mo Peicheng , Chen Jiarong , Pan Xiaoyi , Zhang Jun , Li Kai , Chen Chao
Published: July 2024

Polycrystalline cubic boron nitride (PcBN) cutting tool materials were
prepared by mixing cBN (85 wt.%) and TiN-Ti-Co (15 wt.%) micropowders under
high temperature and ultra-high pressure. X-ray diffraction and scanning
electron microscopy were employed to analyse the phase composition and
microstructure of the composites. The effects of sintering temperature on
the mechanical properties and cutting performance of the PcBN ceramics were
also investigated. The results indicated that at the ultra-high pressure of
6GPa and temperatures ranging from 1400 to 1700?C, the PcBN composites
consist of BN, TiN, TiB2 and Co phases. The PcBN sintered at 1700?C
exhibited the most favourable comprehensive mechanical properties, including
a flexural strength of 909MPa and microhardness of 36.8GPa. In addition, the
cutting tool fabricated from the PcBN composite sintered at 1700?C showed
superior cutting performances in testing with 40Cr mechanical parts.
Trends in value priorities across western Europe - a latent growth curve modeling
Authors: Mentus Vladimir
Published: July 2024

In this paper, we explore trends in value priorities on a countrylevel across
Western Europe using the Schwartz typology of personal values. We analyze
the significance of the time effect as well as country-level differences in
time effects on individual value priorities. We use latent growth curve
modeling and data from the European Social Survey, including 12 countries
(with more than 240,000 respondents) and ten time-points between 2002 and
2020. Results indicate insignificant time effects on tradition and
stimulation, weak positive time effects on benevolence, universalism,
self-direction, and hedonism, and weak negative effects on security,
conformity, achievement, and power. Finally, the analysis of country-level
differences indicates that the observed pattern is particularly pronounced
in the Nordic countries. Generally, our evidence suggests relative stability
of values and a slow cultural shift across Western Europe.
On the road from socialism to capitalism: Attitudes of young people in Bosnia and Herzegovina on economic role of the state
Authors: Jankovic Aleksandar
Published: July 2024

The paper aims to examine the intensity and spread of value orientations of
economic liberalism and redistributive statism among young people in Bosnia
and Herzegovina (BiH) at three points in time - before the collapse of the
socialist social order (1989), in the phase of consolidation of the
neoliberal form of economic regulation after the effects of the global
financial and economic crisis (2012), and after the economic crisis that
came as a consequence of the coronavirus pandemic (2022). The theoretical
framework of the analysis relies on the theory of normative-value dissonance
(Lazic, 2011). We used summative scales of value orientations, where the
data allowed for such analyses, and in other cases, we carried out simpler
forms of descriptive analyses of individual items. The analysis of empirical
data was carried out separately for three datasets: In the first one the
data had been obtained through the research conducted in 1989 in BiH, then
again in 2012 in the Doboj region in BiH, and the third time in 2022 in the
entity of Republic of Srpska. The significance of the research relies on
examining the attitudes of young people related to the economic role of the
state during the establishment of neoliberal capitalism, which has been
insufficiently explored in domestic sociology.
Crowdfunding for health care expenses: Concerns and implications
Authors: Radovanovic Bojana , Kupsjak Jelena , Pantovic Ljiljana
Published: July 2024

The emergence of crowdfunding as a means to gather financial support for
medical expenses has become a global phenomenon. As the prevalence of
medical crowdfunding increases within regional contexts, including in
Serbia, this article aims to offer a framework for understanding this
phenomenon and its ramifications. Drawing upon a review of literature and
research mostly pertaining to Anglo-Saxon crowdfunding practices, we contend
that the proliferation of medical crowdfunding, which is facilitated by
technological advancements, signifies inherent deficiencies within
healthcare systems, exacerbated by the erosion of the welfare state. While
addressing immediate financial exigencies for some individuals, this
practice engenders substantial social, political, and ethical dilemmas.
Structured into three sections, the article contextualizes the catalysts
propelling the emergence of medical crowdfunding, notably the
transformations in welfare regimes. Subsequently, it delves into the
opportunities and challenges presented by crowdfunding for medical expenses,
while the third section delineates the implications for healthcare systems
and policies, underscoring the necessity for research elucidating medical
crowdfunding within the contexts of post-socialist countries.
Application of internal fixator system for anterior pelvic ring with simultaneous application of sacroiliac screw internal fixation of the posterior pelvic ring in Tile C-type unstable pelvic fractures
Authors: Liu Zhongbing , Zou Guoyou
Published: July 2024

Background/Aim. The number of pelvic traumas is increasing globally, mostly due to car accidents but also due to an increasing number of sports and recreational traumas. Tile C-type unstable pelvic trauma (TCUPT) is a kind of high-energy trauma that occurs during traffic accidents or accidents when falling from big heights. The aim of our study was to explore the application of the internal fixation (INFIX) system for the anterior pelvic ring (APR) with simultaneous application of sacroiliac screw (SS) INFIX of the posterior pelvic ring (PPR) in TCUPT. Methods. The subjects (89 of them in total) were recruited among patients with TCUPT from December 2020 to December 2023. A retrospective analysis of the subjects? data was performed, after which the subjects were divided into two groups based on different therapeutic regimens applied: group A (INFIX system for the APR + SS IN-FIX of the PPR, n = 46) and group B (external fixator for the APR + SS INFIX of the PPR, n = 43). Results. In comparison with group B, group A had a shorter period before the commencement of the first activity after surgery, shorter fracture healing time and joint function recovery time, as well as length of hospital stay (t = 6.623, 4.796, 7.992, and 5.227, respectively, p < 0.05). The surgery duration and bleeding volume showed no significant differences between the two groups (t = 1.433, 1.123, respectively, p > 0.05). The fracture reduction outcomes were better in group A than in group B (Z = 2.058, p < 0.05). The incidence rate of complications was lower in group A than in group B (2.17% vs. 18.60%) (?2 = 4.917, p < 0.05). Conclusion. For patients with TCUPT, the INFIX system for the APR with simultaneous application of SS INFIX of the PPR achieves good fracture reduction outcomes.
Auditing Standards and Boards’ Decisions about CEO Risk-Taking Incentives: Evidence from the PCAOB’s Proposed Amendment to Auditing Standard No. 12
Authors: Balsam Steven , Mayberry Michael A. , Park Hyun Jong
Published: July 2024

We exploit a proposed amendment by the Public Company Accounting Oversight Board (PCAOB) to Auditing Standard No. 12 (AS12) to examine its effect on CEOs’ risk-taking incentives. Using a difference-in-differences design, we find that clients with an overlapping director on both the compensation and audit committees, which facilitates greater information sharing, decrease risk-taking incentives relative to control clients following the proposal. We argue that the shared information involves the increased salience of risk-taking incentives to audit committees, who convey a corresponding concern regarding financial reporting consequences to the compensation committee. In additional analysis, we fail to find statistically or economically significant evidence that auditors react to the proposed modification of AS12. Overall, our results are consistent with an unintended consequence of PCAOB standard setting. That is, although the PCAOB asserted that the modification should not impact the design of compensation arrangements, we find evidence that it did.

Comparison of laser induced corneal injury thresholds with safety limits for the wavelength range of 1200–1500 nm
Authors: Schulmeister Karl , Stuck Bruce E.
Published: July 2024

A computer model predicting thresholds for laser induced corneal injury was used to systematically analyze wavelength, pulse duration, and beam diameter dependencies for wavelengths between 1200 and 1500 nm, for the exposure duration regime of 10 μs to 100 s. The thresholds were compared with the maximum permissible exposure (MPE) values to protect the cornea as specified in ANSI Z136.1-2022, ICNIRP 2013, and IEC 60825-1:2014. In the wavelength range between 1200 and 1400 nm, the dominant hazard transitions from the retina to the cornea. Consequently, limits are needed to protect both the cornea and the retina. In the lower wavelength range, the retinal limits are more conservative, while in the higher wavelength range, the corneal limits are lower. Comparison with injury thresholds shows that ANSI MPEs include a large safety margin for all wavelengths. Due to the 7 mm aperture stop defined in IEC 60825-1, levels permitted by the Class 3B limit exceed the predicted injury thresholds for small beam diameters and wavelengths between approximately 1350 and 1400 nm. The Class 3B limit does not appear to be sufficiently protective for these conditions. For skin MPEs, the margin between corneal injury thresholds and MPEs decreases steadily for wavelengths approaching 1400 nm. However, normal eye movements can be expected to reduce the effective exposure so that skin MPEs may serve as adequate limits to protect the cornea for wavelengths less than 1400 nm until a specific limit to protect the cornea is promulgated by ICNIRP.
Further evidence of the southern Mediterranean medicinal leech Hirudo verbana (Annelida, Hirudinea) feeding on fish, with a review of the use of fish hosts by Hirudo spp.

Published: July 2024

Although often considered primarily hematophagous on mammalian blood, the leeches belonging to the genus Hirudo can feed on several other vertebrate hosts. However, to date, little is known about the feeding ecology of medicinal leeches in the wild, and the few available observations mostly deals with the European medicinal leech, Hirudo medicinalis. Since even closely related Hirudo species have different functional morphology and ecological preferences, the observations carried out on one species cannot be automatically generalized to the other medicinal leeches, and targeted surveys must be realised to better understand the feeding habits of these leeches. A wide geographical belt ranging from the Iberian Peninsula to the Caucasus and Central Asia is inhabited by the southern European medicinal leech, Hirudo verbana. Although quantitative data are missing, the species seems characterized by a general decline throughout its distribution range, whose causes are not fully understood. Accordingly, a better understanding of H. verbana dietary composition is crucial to characterise its role in the trophic webs of the ecosystems it inhabits, with important consequences for the correct management of the populations of the species. Here, we report the observation of Hirudo verbana feeding on fish in the wild in southern Italy. This observation constitutes one of the first direct evidences of the species using fish as host organisms, since to date wild H. verbena had been observed mostly feeding on amphibians and mammals. Such information is useful to better characterise the diet of the wild populations of H. verbana, and to understand the trophic resources which could be exploited by the species in different ecosystems. Finally, a review of all the available evidence dealing with the use of fish as hosts organisms by Hirudo spp. is carried out.

Historical Reflections on a Dictator and
Those Who Loved Him
Authors: Argote-Freyre Francis
Published: July 2024

It should be easy to write about a disgraced dictator. Set forth the dirty deeds and be done with it. But no one is ever as simple as their worst transgressions. There is always more to the story. Somebody loved them and has a story to tell as well. As I began to uncover their stories, the task of writing a biography of Cuban dictator Fulgencio Batista, toppled by the Cuban Revolution in 1959, became more challenging. This research note is about one historian’s efforts to navigate the confluence of history, family, and unexpected friendships. 
 
Debería ser fácil escribir sobre un dictador caído en desgracia. Exponer las fechorías sucias sería suficiente. Pero nadie es tan simple como sus peores transgresiones. Siempre hay algo más en la historia. Alguien los amó que también tiene una historia que contar. A medida que comencé a descubrir sus historias, la tarea de escribir una biografía del dictador cubano Fulgencio Batista, derrocado por la Revolución Cubana en 1959, se volvió más desafiante. Esta nota de investigación versa sobre los esfuerzos de un historiador por navegar por la confluencia de la historia, la familia y las amistades inesperadas.

Published: July 2024

O texto busca traçar o perfil das mulheres que participaram, entre 2018 e 2019, do Programa Esporte e Lazer da Cidade em Guanambi-BA. Bem como, analisar como essas mulheres se apropriam do lazer. Utilizou-se do questionário e de entrevista semiestrutura como instrumentos de coleta de dados. A análise aponta que tais mulheres, com idade entre 18 e 59 anos, são majoritariamente negras e casadas, de baixa condição socioeconômica e escolar, que enfrentam barreiras específicas – relacionadas às construções socioculturais do gênero – e dificuldades mais gerais que impactam toda a sociedade brasileira no acesso às atividades e equipamentos de lazer. Nesse sentido, os objetivos do programa circunscrevem a necessidade de ampliar, democratizar e universalizar o acesso ao esporte recreativo e ao lazer  no Brasil.  Portanto, atento aos objetivos elencados acima, o debate aqui apresentado está organizado em dois eixos centrais, isto é, num primeiro momento é feita a descrição e análise acerca do perfil das mulheres participantes do PELC em Guanambi-BA e, por outro lado, na sequência, a discussão sobre as questões relacionadas à apropriação dessas mulheres das atividades e equipamentos públicos de lazer no âmbito do programa em destaque.
SUSPEITA DE TRANSTORNO DO ESPECTRO AUTISTA: INTERVENÇÃO PRECOCE
Authors: Silva Ana Paula Jesus da , Rangel Andressa Braz
Published: July 2024

O Transtorno do Espectro Autista (TEA) é um transtorno do neurodesenvolvimento que afeta o processamento da informação no cérebro, levando a sintomas que incluem prejuízos na interação social e na comunicação. Os sinais e sintomas podem ser observados antes dos três anos de idade da criança, mas o diagnóstico deve ser realizado de maneira cautelosa, considerando as alterações comportamentais que ocorrem durante o desenvolvimento infantil.  A Organização Mundial da Saúde estima que há 70 milhões de pessoas diagnosticadas com Transtorno do Espectro Autista no mundo, sendo dois milhões apenas no Brasil. Com a atual estatística brasileira é necessário um olhar minucioso sobre o diagnóstico e quais as intervenções recomendadas para tratamento do transtorno. A presente pesquisa tem como objetivo realizar uma revisão literária de estudos científicos publicados sobre intervenção precoce em casos de suspeita de TEA.  Para o levantamento dos artigos realizou-se uma busca nas bases de dados BVS e SciELO. O método da Análise do Comportamento Aplicada (ABA), aparece com bons resultados no tratamento, fornecendo um prognóstico esperançoso. O diagnóstico tardio pode causar danos no desenvolvimento da criança, sendo assim, é necessário trabalhar juntamente com uma equipe multidisciplinar identificando sinais e sintomas do transtorno precocemente.
uso do espanhol em sessões orais de Teletandem português-inglês no corpus MulTeC
Authors: Oliveira Rosângela Aparecida Dantas de
Published: July 2024

Este trabalho tem como objetivo investigar os papéis desempenhados pelo uso do espanhol em parcerias inglês-português durante Sessões Orais de Teletandem, indagando sobre sua repercussão nas oportunidades de aprendizagem. Analisamos seis interações orais entre uma brasileira, estudante de inglês, e um estadunidense, estudante de português e de espanhol. Desenvolvemos nossa análise entendendo o trânsito entre os idiomas a partir do ponto de vista da translanguaging (García & Wei, 2014) e o Teletandem (TTD) (Telles, 2015) como uma modalidade de Intercâmbio Virtual (IV) que reúne as condições propícias (affordances) para o desenvolvimento de L2, ao colocar em situações de interação real estudantes que se alternam no papel de proficientes e aprendizes das línguas-alvo (Guichon & Cohen, 2016; Walker, 2017 e 2018; Guichon & Wigham, 2016; Swain, 2006 e Swain & Watanabe, 2012). Por outro lado, questionamos a separação de línguas como um princípio norteador do TTD. Nossos resultados apontam que o uso do espanhol repercutiu positivamente nas oportunidades de aprendizagem para ambos os interagentes, tanto do ponto de vista do desenvolvimento das línguas-alvo, como de outras habilidades envolvidas na construção de sentido, especialmente na interação com falantes estrangeiros. Com relação ao princípio da separação de línguas no TTD, nossas conclusões vão ao encontro dos estudos de Picoli & Salomão (2020) e Satar et al.  (2024) e reiteram a necessidade de relativizá-lo tendo em vista as perspectivas atuais de aprendizagem e ensino de línguas.
The Hardness of the Practical Might
Authors: Tenenbaum Sergio
Published: July 2024

Incommensurability is often introduced with the small improvement argument. Options A and B are shown to be incommensurable when it is neither the case that A is preferred to (or better than) B nor that B is preferred to (or better than) A, but a slightly improved version of A (A+) is still not preferred to B. Since A+ is preferred to A, but not to B, we must also conclude that it is also true that A and B are not indifferent (or equally good). Such incommensurable options seem incompatible with orthodox decision theory (and various forms of value theory) but options that obey the pattern described by this argument seem ubiquitous: my choice between lemon tarts and eclairs at my favourite pastry shop might exhibit this pattern, but so could my choice between jobs or careers. In trying to accommodate incommensurable options within various frameworks, philosophers have argued that we must preserve certain central features of the phenomenon. Among them is the supposed “hardness” of at least some incommensurable options: even if perhaps one would need to be a rather anxious gourmet to describe the choice between lemon tarts and eclairs as hard, the choice among careers could potentially be agonizing. However, it is not clear in which way choices among incommensurable options are “hard,” nor how and whether such hardness poses problems for the various accounts of incommensurable choices. To complicate matters, the deontic verdicts for choices between incommensurable options seem to be relatively straightforward: one appealing view is that in such circumstances I am rationally permitted to choose any option that is not worse than another option. This paper aims to provide a sharper formulation of at least a version of the hardness problem, to argue that various theories of incommensurability fail to account for the hardness of some incommensurable choices, and to propose that the theory of instrumental rationality I develop in Rational Powers in Action, aided by a Kantian insight, promises to provide an adequate explanation of the hardness of choice among incommensurable options.
What’s so Hard about Hard Choices?
Authors: Chang Ruth
Published: July 2024

What, exactly, is so hard about hard choices? I suggest that what is distinctively hard about hard choices is that they present us with the volitional difficulty of putting ourselves behind an alternative and thereby making it true of ourselves that we have most reason to do one thing rather than another. Making it true through your commitments that, for instance, you have most reason to be a philosopher rather than a lawyer makes the choice between the careers hard. This answer is in contrast to that of Sergio Tenenbaum, who understands the hardness of a hard choice as a deliberative difficulty in specifying our alternatives and ends in ways that conform with certain proposed constraints of rationality. For Tenenbaum, the hardness of hard choices is not distinctive to such choices but is a general difficulty rational agents face when they need to further specify their alternatives and ends, even if the choice is easy.
Self-Control and Planning: A Reply to Williamson
Authors: Andreou Chrisoula
Published: July 2024

In Timothy Luke Williamson’s commentary on my article “Micromanagement and Poor Self-Control,” Williamson casts my focus on managerial failures in certain cases of poor self-control “as an especially fruitful tool for addressing problems of poor self-control”; but he suggests that the cases of poor self-control that I view as cases of managerial failure also involve control by a foreign force, in accordance with the “foreign force paradigm,” which I claim is off base in the cases on which I focus. Although I cannot get into Williamson’s entire interesting and elaborate argument, I here question The Weak Planning Perspective, which plays a key role in Williamson’s critical response, with the aim of addressing the issues he raises and shedding some light on why and how our views diverge.

Freshwater fish farming has high appeal among the public, however the process of feeding fish is still mostly done manually using traditional methods that are less effective. This article discusses the implementation of fish feed with a throwing system based on an integrated system using an ultrasonic sensor, DC motor, and 5V relay with an Arduino Uno microcontroller. Feeding fish is an important aspect of fish farming. Currently, fish feeding methods are still mostly done manually by throwing bait by hand. These manual techniques tend to be ineffective and can result in irregular feeding. For example, using a bucket to throw food directly into a fish pond can cause the fish to eat too much without proper control. This can result in excessive feeding, additional costs, and poor air quality. Therefore, it is necessary to develop an automatic and programmed fish food throwing system to increase the efficiency and effectiveness of feeding. It is hoped that the use of ultrasonic sensors, DC motors and 5V relays with the Arduino Uno microcontroller can provide a solution to overcome this problem. The main objective of this research is to design and implement an embedded system-based fish feed launcher that can provide feed automatically with good control. This system is expected to improve fish quality, reduce additional costs, and provide convenience for fish farmers. The problem that this tool wants to solve is how to increase the efficiency and effectiveness of fish feeding in freshwater fish farming. Currently, feeding is still done manually, and uncontrolled feeding frequency can result in problems such as excessive feeding and poor air quality. The implementation of a throwing system based on an embedded system with an ultrasonic sensor is expected to be able to overcome this problem by providing feed automatically and programmed. Thus, this research aims to create innovative solutions in fish feeding that can increase production efficiency and the welfare of fish farmers.

The halal industry has been triggered by the reported discovery of imported halal meat, like meat smuggling, fake halal logos, meat fraud and cartel meat issue. The meat smuggling incidence in the past 40 years had an unfavourable impact on the confidence level of Muslim consumers towards imported halal meat. Thus, this study is conducted to examine the confidence level of Muslim consumers towards imported halal meat. This study aims to investigate the knowledge of Muslim consumers towards imported halal meat and their confidence level. The quantitative approach has been adopted to achieve the research objective, where the data is collected via survey using Google Form. The questionnaires were distributed to 120 respondents consisting of Muslim consumers in Selangor. The collected data has been analysed adopting descriptive, frequency, reliability and correlation analysis using SPSS v.29. The findings indicated that 40.8% (49 respondents) still feel uncertain and less confident about purchasing imported halal meat in the market. However, the result showed that 71.7% (86 respondents) had shown positive signs of awareness about imported halal meat and are always sensitive to issues related to imported halal meat that often occur in Malaysia, such as the issue of fake halal logos found on the packaging of imported meat, meat products or any other food products. It is recommended that halal-related authorities or agencies work hand in hand to provide and promote clear information on imported halal meat especially on the recognised foreign halal logo by the Department of Islamic Development Malaysia (JAKIM).

The banking sector in Malaysia has seen substantial changes since the global financial crisis, with a greater focus now being placed on the value of risk management. The study aims to examine the impact of internal and external bank risks on Malaysia’s profitability. Utilising unbalanced panel data from 2010 to 2022, it includes 29 banks, comprising 14 Islamic banks and 15 conventional banks. The random effect model is found to be the most appropriate for the full samples and Islamic banks, while the fixed effect model is the preferred choice for conventional banks. Notably, Islamic banks tend to be less profitable compared to conventional banks. Even though Islamic banks display lower profitability compared to conventional banks, they have greater resilience, and their profitability is less impacted during crisis periods compared to conventional banks. Stronger resilience in Islamic and conventional banks is important to ensure sustainability and profitability.

The study focuses on the funding fragility arising from the nature of the banking business due to asset-liability mismatches. Incorporating seven (7) countries with dual banking systems, the study aims to assess the global funding fragility of Islamic and conventional banks. The study employs a random effect model with a robust standard error that spans the period from 2009 to 2018, made up of 10-year unbalanced panel data. Islamic and conventional banks should be more cost-efficient and earn greater profitability to reduce funding fragility. Banks with wider income diversification and a higher capital level have a better advantage in lessening funding fragility. Banks that offer high financing growth are exposed to greater credit risk but empirically manage to control the funding fragility. The interaction effect reveals that larger conventional banks are less fragile than smaller conventional banks. On the contrary, larger Islamic banks are found to be more fragile than smaller Islamic banks.

Published: July 2024

Rice plays an important role in the economic, social, and political stability of ASEAN. The presence of the ASEAN Economic Community (AEC) in 2015 shows that market integration in ASEAN is becoming more real. The objective of this study is to analyze trends in rice imports and exports in ASEAN, integration of rice markets, causality relationships, and impulse response based on rice prices in the ASEAN. Data used include annual data on import and export of rice from Indonesia, Malaysia, the Philippines, Thailand, and Vietnam in 2000-2021 as well as monthly data on rice price in 2017.1 - 2021.12. The methods used are trend analysis, Johansen cointegration test, Vector Autoregression (VAR) estimate with Vector Error Correction Model (VECM), Granger causality test, and impulse response analysis. The result is that the trend pattern of rice imports in Indonesia tends to decrease, while the trend of imports to Malaysia and the Philippines as well as exports to Thailand and Vietnam rises every year. There is integration of the rice market in ASEAN as well as a pattern of coherent and reciprocal inter-national causal relations.

Changes in economic behavior can be an obstacle for MSMEs, because there are still many MSMEs that are not ready for the changes that are occurring. In fact, the changes that often occur in the economic world can actually be used as a success factor for competitive advantage, if the company is able to take the right steps and strategies in a short time. This research aims to show strategies that can be used to increase the competitive advantage of MSMEs by involving strategic agility and through organizational ambidexterity as mediating variables. The population of this research is MSMEs in the culinary sector in Bandar Lampung City, namely 1,162 MSMEs. The total sample was 298 respondents obtained using the Slovin method. The analysis method uses a structural equation model (SEM) approach with the SmartPLS application. The research results show that strategic agility can have a positive and significant effect on competitive advantage. Strategic agility has a positive and significant effect on organizational ambidexterity. Organizational ambidexterity can have a positive and significant effect on competitive advantage. And organizational ambidexterity is able to mediate the influence of strategic agility on competitive advantage. Apart from that, MSMEs must be run in accordance with Islamic business ethics.

Published: July 2024

Graphene oxide nanoparticles with higher thermal conductivity aid in enhancing the flow and heat transport in magnetohy-drodynamic devices such as magnetohydrodynamic pumps. Modelling such devices with promising applications inherently necessitates entropy studies to ensure efficient models. This investigation theoretically studies the entropy generation in magnetohydrodynamic flow of graphene oxide in an inclined channel. Buongiorno nanofluid model is used including the impacts of nanoparticle attributes, namely thermophoretic and Brownian diffusion along with viscous dissipation effects. The spectral quasi-linearization method with Chebyshev’s polynomials is adapted to solve the differential equations under slip conditions. On studying the effects of implanted parameters, it is concluded that the conductive heat transfer enhancement by the Hartmann number is remarked. The Bejan number is found to be greater than 0.9 and hence, heat transfer primarily causes the entropy generation. A good agreement is found between the results for special cases and the results from the literature. Furthermore, investigations conclude that entropy is contributed primarily by heat transfer.
