Enhancement of heat dissipation efficiency in the CSNS target through the innovative design of a serial cooling water channel
Authors: Chen Jiahui , Tong Jianfei , Lu Youlian , Wang Songlin , Liang Tianjiao
Published: September 2024

This paper presents a coupling of the Monte Carlo method with computational fluid dynamics (CFD) to analyze the flow channel design of an irradiated target through numerical simulations. A novel series flow channel configuration is proposed, which effectively facilitates the removal of heat generated by high-power irradiation from the target without necessitating an increase in the cooling water flow rate. The research assesses the performance of both parallel and serial cooling channels within the target, revealing that, when subjected to equivalent cooling water flow rates, the maximum temperature observed in the target employing the serial channel configuration is lower. This reduction in temperature is ascribed to the accelerated flow of cooling water within the serial channel, which subsequently elevates both the Reynolds number and the Nusselt number, leading to enhanced heat transfer efficiency. Furthermore, the maximum temperature is observed to occur further downstream, thereby circumventing areas of peak heat generation. This phenomenon arises because the cooling water traverses the target plates with the highest internal heat generation at a lower temperature when the flow channels are arranged in series, optimizing the cooling effect on these targets. However, it is crucial to note that the pressure loss associated with the serial structure is two orders of magnitude greater than that of the parallel structure, necessitating increased pump power and imposing stricter requirements on the target container and cooling water pipeline. These findings can serve as a reference for the design of the cooling channels in the target station system, particularly in light of the anticipated increase in beam power during the second phase of the China Spallation Neutron Source (CSNS Ⅱ).
Thermodynamic evaluation of an IGCC power plant utilizing allothermal gasification
Authors: Choudhary Nitesh Kumar , Ghosh Sourov , Karmakar Sujit
Published: September 2024

The present work conducts a comprehensive thermodynamic analysis of a 150 MWe Integrated Gasification Combined Cycle (IGCC) using Indian coal as the fuel source. The plant layout is modelled and simulated using the “Cycle-Tempo” software. In this study, an innovative approach is employed where the gasifier's bed material is heated by circulating hot water through pipes submerged within the bed. The analysis reveals that increasing the external heat supplied to the gasifier enhances the hydrogen (H2) content in the syngas, improving both its heating value and cold gas efficiency. Additionally, this increase in external heat favourably impacts the Steam-Methane reforming reaction, boosting the H2/CH4 ratio. The thermodynamic results show that the plant achieves an energy efficiency of 44.17% and an exergy efficiency of 40.43%. The study also identifies the condenser as the primary source of energy loss, while the combustor experiences the greatest exergy loss.

Meinong and Twardowski on Representations and Judgements
Authors: Raspa Venanzio
Published: September 2024

This paper discusses the intellectual relationship between Meinong and Twardowski, focusing on their ideas about representations and judgements, which are in part extraneous to Franz Brentano’s philosophy. The two philosophers addressed similar topics and their respective positions can be seen to overlap in some regards. This is shown by looking at their views on judgements about relations, intuitive and non‑intuitive representations, and Twardowski’s represented judgements, which display some strong analogies with Meinong’s assumptions.
Semantical Issues in Maria Kokoszyńska’s Letters to Kazimierz Twardowski
Authors: Chybińska Alicja
Published: September 2024

Maria Kokoszyńska‑Lutman, the outstanding female member of the Lvov‑Warsaw School, played an important role in the rise of the modern version of semantics. She very early noticed the importance of Alfred Tarski’s results for the established tradition of Lvov‑Warsaw investigations on truth, including Twardowski’s refutation of relativism. She contributed to the common recognition of these results, among others in Vienna and during the Congress for the Unity of Science in Paris in 1935. In the paper, I examine some Kokoszyńska’s semantical views. They are supplemented by the translation of Kokoszyńska’s letters to Kazimierz Twardowski written from Vienna and Paris.
Mieczysław Wallis – historyk sztuki czy filozof?
Authors: Zegzuła-Nowak Joanna
Published: September 2024

The paper presents a scientific profile of Mieczysław Wallis in the perspective of the question of his intellectual status. The author looks for the answer within two areas that were the subject of Wallis’ interest: philosophy and history of art. She analyses the path of Wallis’ intellectual development and the formation of his creative interests: from his education (in Heidelberg and Warsaw) and inspirations, through his first intellectual concerns, to an analysis of his scientific output. In his youth, Wallis wrote about the desire to create a philosophical system. Did this aspiration determine his scientific work, and to what extent? Did it set the course of his intellectual path? Was Wallis’ profile dichotomous in nature? For, as a philosopher, Wallis asked himself a fundamental question about the phenomenon of human being and its relation to the world. As a historian of art, he sought the answer by analyzing the world of man’s creative activity, his aesthetic experiences and artistic creations. Thus, on the one hand, the author emphasizes the role of philosophy in the development of Wallis’ intellectual views; on the other hand, she points to the philosophical depth of his achievements in the field of art theory.
Czy psychologia szkoły lwowsko‑warszawskiej ma coś do zaoferowania współczesnej psychologii?
Authors: Citlak Amadeusz
Published: September 2024

At the end of the 19th century, two monographs on empirical psychology were published: W. Wundt’s Grundzüge der physiologischen Psychologie and F. Brentano’s Psychologie vom empirischen Standpunkt. They set different research standards, indicating a differently defined subject as well as the methodology of the new science. The psychology of the 20th and 21st centuries focused mainly on Wundt’s program, while Brentano’s program was included in philosophical analyses. However, this led to significant changes in psychology, which today can be seen as deep reductionism, narrowing the subject matter, and difficulties in constructing theories. In the article, I suggest that it might be helpful to recall the basic assumptions of Brentano’s psychology and the schools derived from it, such as e.g. the Lvov‑Warsaw School. Therefore, the article aims to indicate the theoretical space that has been emerging for some time, in which the school of Kazimierz Twardowski could present original philosophical and psychological achievements.

Published: September 2024

With the rapid development of science and technology, computer-aided technology has been widely used in the field of education, but in the field of innovation and entrepreneurship education (Hereinafter referred to as IEE), there are still problems such as uneven distribution of resources and the disconnection between teaching content and actual needs. This paper puts forward a new model framework of computer-aided IEE, which is student-centered and practice-oriented. Through clear teaching objectives, rich course content, diverse teaching methods, and a scientific evaluation system, students’ innovative consciousness and entrepreneurial ability are comprehensively improved. The course covers innovative thinking, business models, market research, and other theoretical knowledge, and introduces virtual reality (VR) and augmented reality (AR) technologies to simulate the real entrepreneurial process and provide a practical platform. In the aspect of algorithm application, the research combines the content recommendation algorithm and collaborative filtering recommendation algorithm, constructs accurate user portraits by analyzing students’ learning behavior data, and matches them according to the characteristics of learning resources to recommend personalized learning resources for students. At the same time, the learning path optimization algorithm is developed, and the personalized and efficient learning path is planned by using the shortest path algorithm in graph theory to ensure that students can master the required knowledge in the shortest time. The experimental part designed a one-semester teaching experiment, and compared the differences between the experimental group and the control group in academic performance, learning participation, and satisfaction. The results show that the computer-aided IEE model significantly improves students’ academic performance, learning participation, and satisfaction, which verifies the effectiveness of the model. The research on the model and algorithm of computer-aided IEE proposed in this paper provides new ideas and methods for IEE, and helps to cultivate more high-quality talents with innovative thinking and entrepreneurial ability.

An Exploration of Consumers' Response to Online Service Recovery Initiatives
Authors: Ozuem Wilson , Patel Amisha , Howell Kerry E. , Lancaster Geoff
Published: September 2024

The focus of this paper is on levels of service failure and recovery strategies in relation to UK online fashion retailers. In a changing social, political and economic environment the use of information technology has permeated all forms of organisations: from private to public, local to global, old and new. Parallel with this development, companies have developed and experimented with new means of interacting with customers, and have devised and applied a variety of marketing strategies. The deployment of the internet, along with its subsets, has created a number of new opportunities, as well as a range of uncertainties and burdens, particularly on consumer perceptions of service quality, service failure and recovery. This paper contributes to extant knowledge and offers an understanding of behavioural-related issues, e.g. understanding consumer behaviour in the development of innovative business models in the industry.
PC, Phone or Tablet?: Use, Preference and Completion Rates for Web Surveys
Authors: Brosnan Kylie , Grün Bettina , Dolnicar Sara
Published: September 2024

This study investigates whether it is the case that representativity is undermined if personal computer, tablet and smartphone respondents differ in socio-demographic characteristics and display different survey completion rates. Online market research is struggling with sample representativity. The analysis of more than ten million survey invitations, as well as stated device preference information, suggests that web survey respondents who are members of online panels still mostly use their personal computers, but do express increasing interest in using smartphones and tablets. Survey completion rates do vary across devices, and device use is significantly associated with socio-demographic characteristics and length of membership on a panel. Therefore, researchers must not limit respondents to use a specific device for completing a survey as this may compromise the quality of the survey completion experience, increase non-response error and negatively affect representativity.
BPC/MRS Enquiry into Election Polling 2015: Ipsos MORI Response and Perspective
Authors: Mortimore Roger , Baines Paul , Worcester Robert , Gill Mark
Published: September 2024

This Forum article considers the unsatisfactory results of pre-election opinion polling in the 2015 British general election and the BPC/MRS enquiry report into polling by Sturgis et al., providing a response from Ipsos MORI and associated researchers at King's College London and Cranfield Universities. Whilst Sturgis et al. (2016) consider how to perfect opinion poll forecasting, why the 2015 prediction was inaccurate when the same methodology returned satisfactory results in 2005 and 2010 at Ipsos MORI is considered here instead. We agree with Sturgis et al. that the inaccurate results were not due to late swing or the ‘shy Tory’ problem and with Taylor (2016) that the underlying problem is a response rate bias. However, Sturgis et al. critique pollsters in their report for systematically under-representing Conservative voters but the Ipsos MORI final poll had too many Conservatives, too many Labour voters and not enough non-voters. The Sturgis et al. conclusion is convincing that the politically disengaged were under-represented due to quotas and weighting mechanisms designed to correct for response bias. Nevertheless, for Ipsos MORI, this explanation does not account for why the polling methodology was inaccurate in 2015 when it had performed accurately in 2005 and 2010. For Ipsos MORI, a more likely explanation is that Labour voters in 2015 became more prone to exaggerate their voting likelihood. We offer various postulations on why this might have been so, concluding that to account for the inaccuracy requires a two-fold response, to improve: (i) sample representativeness and (ii) the projection of voting behaviour from the data. Unfortunately, the BPC/MRS report offers no blueprint for how to solve the problem of sampling the politically disengaged. Whilst Ipsos MORI have redesigned their quotas to take account of education levels, to represent those better with no formal educational qualifications and reduce overrepresentation of graduates, polling in the referendum on EU membership suggests that the problem of drawing a representative sample has been solved but difficulties in how best to allow for turnout persist.
Internationally Mobile Students and their Brands

Published: September 2024

Given the increase in the volume of student mobility, this study explores how internationally mobile students, who are at the starting point of their life as global nomads, represent and give sense to the relationship with their brands in the context of relocation for study purposes. This qualitative research elicits the spontaneous and intimate reconstruction of young consumer-brand relationship dynamics in conditions of mobility by means of digital diaries. Evidence highlights the interactive and eudaimonic properties that young consumers attribute to branded objects for the support they provide in the fulfilment of their day-to-day activities and in the achievement of the challenges connected to the construction of their life project as mobile individuals.
Predicting Wine Repurchase
Authors: Williamson Patricia Osidacz , Loose Simone Mueller , Lockshin Larry , Francis Leigh
Published: September 2024

The aim of this study is to extend an existing method to untangle the effect of taste (intrinsic) versus label information (extrinsic) on repurchase in a new-to-wine market. Results from a repeated discrete choice experiment (DCE) conducted before and after tasting a set of wines in China are compared with a control group that only performed the repeated DCE, but not the informed tasting. Fundamental differences were observed in choice response for the control group between the two sets, indicating a low stability of preferences and low test-retest reliability. There was a narrow range of responses for both the control and test groups, with an unusually high number of random choices recorded. The effect of extrinsic and intrinsic product attributes could not be determined. The method of combining discrete choice and tasting should be reassessed first in an established market. Other recommendations for conducting similar research in developing markets are discussed.
Ideal and Maximum Length for a Web Survey
Authors: Revilla Melanie , Ochoa Carlos
Published: September 2024

This paper aims to discover ‘How long can/should a survey be?’ by asking the question to respondents themselves in a web survey implemented by the Netquest fieldwork company in Mexico in 2016. It is a question that is frequently asked, even if research has already been carried out on the impact of survey length on non-response or data quality. The study conducted for this paper concluded that the ideal survey length is a median of 10 minutes and that the maximum survey length is 20 minutes. The reported lengths were significantly linked to the fact that respondents liked answering the survey and that they trusted that their data are treated in an anonymous way, but were not found to be linked to the socio-demographic variables tested, except age in the case of maximum length.

Assessing the Level of People’s Satisfaction with the Quality of Information About Administrative Procedures on the National Public Service Portal in Yen Hoa Ward, Cau Giay District, Hanoi City
Authors: Thi Ngoc Thao Nguyen , Thi Kim Chi Doan , Thi Ha Phuong Nguyen
Published: September 2024

On March 12, 2019, Prime Minister Nguyen Xuan Phuc signed the "Decision approving the National Public Service Portal (NPSP) Project" with the goal of improving the quality and efficiency of public services. However, after five years of implementation, certain limitations in conducting administrative procedures on the NPSP have affected people's satisfaction. From that reality, the authors were motivated to conduct research on the topic to contribute measures to minimize the difficulties of people in the area. By combining a comprehensive literature review with structured surveys involving a sample of 162 residents from Yen Hoa Ward, Cau Giay District, Hanoi, the authors revealed that while citizen satisfaction with the quality of information on administrative procedures on the NPSP is generally high, there is inconsistency across different aspects when evaluated against internationally verified assessment criteria and scales. Through that current situation, the research team offered some insights and proposed measures to further improve the quality of information on administrative procedures on the national public service portal to increase people's satisfaction with the service.

Higher education institutions simultaneously perform the functions of education and scientific research, including basic and applied research. Inventions are one of the outcomes of applied research. Statistics show that during the period from 2019 to 2023:
- Vietnamese higher education institutions were granted 141 invention patents out of 779 invention registration applications submitted, with a protection rate of 18.10%;
- Vietnamese higher education institutions were granted 205 utility solution patents out of 496 utility solution registration applications submitted, with a protection rate of 41.33% (the lowest in both quantity and protection rate compared to individuals, enterprises, and research institutes).
The article analyzes the inventions deemed to lack novelty, the main reasons for the refusal of patent protection for inventions from Vietnamese higher education institutions, and proposes solutions to improve the patent protection rate for these institutions.

Masterplan desa merupakan dokumen perencanaan di tingkat desa yang bersifat komprehensif. Secara geologi Desa Palluda Kecamatan Pujananting memiliki beragam sumberdaya bahan galian salah satunya adalah kromit. Bijih kromit memiliki banyak Kegunaan dalam industri-industri stainless steel, gray cast iron, iron free high temperature alloys, dan lain-lain. Atas dasar tersebut sehingga diperlukan suatu upaya guna menunjukan sebaran (distribusi) dari sumberdaya kromit khususnya di Desa Palluda, yang mana berdasarkan observasi awal di kantor desa Palluda belum terdapat peta sebaran bahan galian kromit khususnya untuk masterplane geowisata Desa Palluda, Kecamatan Pujananting, Kabupaten Barru. Tujuan dari kegiatan Pengabdian kepada masyarakat ini adalah untuk membuat peta sebaran kromit kemudian memberikan rekomendasi terkait pengembangan masterplane kromit untuk geowisata. Metode pelaksanaan kegiatan ini yakni melakukan identifikasi awal (observasi), identifikasi masalah, dan pemberian solusi. Temuan pengabdian ini menyoroti potensi sumber daya kromit yang signifikan di Desa Pattapa, Kabupaten Barru, Sulawesi Selatan, untuk pengembangan masterplan geowisata. Analisis spasial dan survei geologi yang dilakukan dalam pengabdian ini memberikan pemahaman menyeluruh mengenai lokasi, sebaran, dan karakteristik endapan kromit di wilayah tersebut. Kemampuan pemanfaatan sumber daya kromit di Kabupaten Barru dapat berkontribusi terhadap pertumbuhan ekonomi dan diversifikasi perekonomian daerah, karena geowisata dapat menghasilkan pendapatan, menciptakan lapangan kerja, dan mendorong pelestarian warisan alam dan budaya daerah. Peta potensi kromit komprehensif yang dikembangkan dalam studi ini dapat menjadi alat yang berharga bagi pemerintah daerah dan pemangku kepentingan di Kabupaten Barru untuk merencanakan dan melaksanakan rencana induk geowisata yang selaras dengan tujuan pembangunan berkelanjutan di wilayah tersebut.

Objetivo: Descrever os efeitos da insulina tópica no tratamento de patologias corneanas. Revisão bibliográfica: A insulina é um hormônio protéico produzido pelas células beta do pâncreas, que desempenha um papel fundamental no controle glicêmico e nos processos metabólicos do corpo humano. Além dessas funções, a insulina é crucial na reparação tecidual, pois ativa citocinas anti-inflamatórias e promove a cicatrização de tecidos. A córnea, uma estrutura ocular transparente, convexa, avascular e altamente inervada, atua como uma barreira protetora contra lesões e agentes infecciosos, desempenhando um papel essencial na proteção das estruturas internas do olho. No tratamento de patologias corneanas, a insulina tópica tem se mostrado eficaz na reepitelização de defeitos epiteliais persistentes, o que reduz a necessidade de intervenções cirúrgicas. Dessa forma, a insulina tópica pode melhorar a recuperação da córnea e minimizar complicações associadas aos tratamentos tradicionais. Considerações finais: A insulina tópica em patologias corneanas tem se mostrado eficaz apresentando boa disponibilidade, baixo custo e excelente tolerância.

Objectives

To analyze the dose to the left anterior descending artery (LAD) in patients who have received radiotherapy for left breast cancer with Deep Inspiratory Breath Hold (DIBH) technique and compare it with other cardiac dosimetric parameters, as well as the accepted dose constraints.

Materials and Methods

20 patients (10 prospective and 10 retrospective) were selected for this study. All patients underwent 2 non-contrast radiation planning CT scans of 2.5 mm thickness - one with DIBH and one with free breathing. Contouring was done using the Radiation Therapy Oncology Group (RTOG) guidelines. LAD was delineated and given a PRV of 3 mm and 5 mm. Dose-volume histograms (DVH) were used to obtain the data from the approved plans.

Results

The lung volume receiving 17 Gy in percentage, Dmean of the heart, LAD Dmean and Dmax, and the Dmean and Dmax received by 3 mm and 5 mm PRVs were both very well achieved when compared to the dose constraints given by the DBCG HYPO trial. The study found a higher correlation between the mean heart dose and the 5 mm PRV dose (R2 = 0.81 and 0.71 respectively for the mean and max dose) than the 3 mm PRV, and a positive correlation between the heart dose and LAD making it a useful structure for predicting acute cardiac events.

Conclusion

The study of 20 patients found that DIBH is effective to minimize cardiac dose and potentially cardiac toxicity, with heart and LAD doses being comparable or lower compared to other studies. The LAD doses recorded were significantly less than those in non-DIBH studies, demonstrating the feasibility of routine contouring and recording LAD dose in left-sided breast radiation patients. Further research is needed to determine the dosimetry and clinical consequences of the Dmean and Dmax of the 5mm PRV to the LAD.
