Boron carbide (B4C)-reinforced metal matrix composites (MMCs) are materials of choice for the manufacturing of radioactive material containers due to their neutron absorption properties. The neutron absorption capacity of this material depends mainly on the density of B4C particles in the aluminum matrix. The reinforced MMC sheets used to manufacture these containers are produced by a lamination process. The raw sheets coming out of the rolling mill show uneven distribution of B4C particles between the extremities of the sheets, constituted solely of aluminum (rejection zone), and the interior of the laminated sheet, with the right aluminum / B4C ratio (useful zone). Detecting the boundary between the useful zone and the rejection zone is a crucial step in the process, as it defines which part of the sheet should be used to manufacture the containers. Determination of this boundary is currently carried out by chemical digestion, which is costly, time-consuming, and provides only localized information. The aim of this work was to develop a non-destructive technique able to detect the boundary between the rejection zone and the useful zone. The approach is based on the difference in acoustic attenuation between rejection and useful zones. More precisely, the ultrasonic parameter used was the amplitude ratio between the backwall and the front wall echo of the sheet when performing a pulse-echo inspection at 20 MHz. The amplitude ratio in aluminum is smaller than in the useful zone containing B4C, which is more attenuating for the ultrasounds. Two types of scans were performed: 1D linear scan and 2D scan. The linear scan was performed using a conventional probe coupled to the part via a conformable wedge. The boundary between both zones was detected by segmenting the amplitude ratio profile into different sections with constant statistical parameters. The 2D scan was performed with an automated 5-axis inspection system in a water tank using a conventional probe. A map of amplitude ratios was generated, and the useful zone was detected using an agglomerative clustering segmentation. Validation was carried out by comparing the amplitude ratio profile with chemical digestion data from samples taken from these sheets. Experimental validation, performed on sheets with different B4C densities and thicknesses, showed that amplitude ratio enables a good detection of the boundary and therefore the useful zone.

Traditional Non-Destructive Testing (NDT) methods for heat exchangers inspections struggle with both efficiency and accuracy. These methods are time-consuming, prone to errors in data interpretation, and heavily reliant on skilled technicians, who are becoming a scarce resource. Artificial intelligence (AI) tools offer a promising alternative, by providing a faster, more automated solution. This study assesses an AI system's performance using Probability of Detection (POD), a key NDT metric. Due to the cost of experimental POD, we leverage numerical simulation with CIVA software to generate large datasets. POD curves are created to evaluate the AI's capabilities across various heat exchangers conditions. Simulations demonstrate the AI's ability to detect indications even with significant noise affecting the signal. The findings are corroborated by real-world testing, which achieved a 97.7% POD for a selected set of indications deemed critical. This study highlights the potential of AI and simulation to improve NDT for critical infrastructure.

NDT personnel face many of the same conventional hazards as workers in other fields. However, NDT personnel may also be exposed to radiation, either from industrial radiography or because they work in a radioactive environment such as a nuclear plant. This talk will discuss the risks posed by radiation by focussing on the views and evidence presented by a leader in the regulatory community who ensures safety by applying conservative radiation protection rules.
On Hannah Arendt’s Aestheticism
Authors: Blattberg Charles ,   Saint Louis University
Published: July 2024

Hannah Arendt’s politics is aesthetic rather than practical, motivated by enjoyment rather than well-being, and so it should be rejected. I begin with an account of aestheticism as the doctrine according to which seemingly non-aesthetic things are actually aesthetic, parts of a whole dimension of reality that we might simply call “the aesthetic.” We access it by taking a disinterested attitude, one that affirms things for their own sakes, and there are four ways of doing this: disinterested appreciating (e.g., of beautiful art), fun playing, fantasizing, and putting on shows or spectacles. While Arendt’s politics takes a classical republican form that is like a competitive game, an analysis of her conceptions of acting and judging reveals that the modes of disinterested showing and appreciating are also present. Her philosophy has another motivation, however, alongside enjoying the aesthetic: the need to escape the reality of evil.

Corporate Governance and the Value Relevance of Financial Information in Tanzanian Savings and Credit Cooperatives: A Panel-Data Approach
Authors: Mwakapala David A. , Mbogela Cosmas S. , Ngomuo Sarah
Published: July 2024

The study examined the influence of corporate governance on the relevance of financial information towards the value of Savings and Credit Cooperative Societies (SACCOS) in Tanzania. Thus far, evidence on how corporate governance influences the relevance of financial information in cooperative societies is limited globally, notably in emerging economies. Therefore, this research contributes to the body of knowledge by extending the application of agency theory to determine this relationship among variables. The study specifically employed a quantitative panel data set of 202 SACCOs from 2013 to 2020 that was gathered from yearly financial reports and processed through descriptive analysis and regression models. Descriptive statistics demonstrate that the SACCOs' value in Tanzania is increasing. Empirical results show a significant positive relationship between earnings financial information and the value of SACCOS; the book value of equity financial information insignificantly influences the value of SACCOS. The findings deliver empirical and theoretical backing for the notion that board size, skills and supervisory committee skills have a significant impact on the relevance of financial information towards the value of the firm. However, the examination showed no proof that the number of meetings affected the relevance of financial information. This implies that Policymakers should make reforms that will enable SACCOs to improve the quality of financial information and widen the publication of financial reports through effective corporate governance, including the emphasis on online publications.

Authors: Kholil Munawar , Rahman Abdur , Anshory Muhammad Isa
Published: July 2024

Etiquette (adab) must be a primary focus for students (santri) in modern pesantren (Islamic boarding schools), especially for those studying religious knowledge. The aim of learning adab is to ensure that the knowledge gained is beneficial and blessed, as a small amount of knowledge accompanied by adab is better than a large amount of knowledge devoid of adab. The role of pesantren is vital in the cultivation of adab (ta'dib) among its students. The methods of instilling adab include: 1) Teaching methods, which encompass classroom learning and the study of religious texts (ta'lim kitab). 2) Mentorship methods, which include: role modeling, advice and motivation, training and habituation, discipline, rewards, and punishments. Therefore, pesantren are expected to produce competent and ethical Islamic leaders.
Le droit des animaux en France : Droit positif, droit prospectif et appréhension du droit du vivant
Authors: Regad Caroline , Riot Cedric
Published: July 2024

A l’ère de l’Anthropocène, les humains sont devenus la principale force de changement (pour ne pas dire de contrainte) sur l’évolution de la Terre. Au minimum, notre rapport au vivant doit être repensé et le droit pourrait être le meilleur vecteur de ces réflexions. Pour notre part, nous pensons que l’anthropocentrisme juridique est actuellement ébranlé et que nous en sommes au début d’un mouvement qui va prendre de l’ampleur et se développer à l’avenir, notamment en raison des avancées actuelles du zoocentrisme et du biocentrisme avec des droits accordés aux animaux et/ou à (des éléments de) la Nature. Notre contribution portera plus spécifiquement sur le droit des animaux en France où nous aborderons les textes de droit positif, en inscrivant certains d’entre eux dans le cadre de nos travaux sur la personnalité juridique, question majeure pour la protection des animaux et de toute entité naturelle.
The Influence of Artificial Intelligence on Human Activity and Human Intelligence
Authors: Sfetcu Nicolae ,   Romanian Academy
Published: July 2024

The influence of the evolution of artificial intelligence on human activity and human intelligence is a multifaceted topic that encompasses various dimensions such as societal implications, cognitive enhancement, educational methods, and decision-making processes. The impact of AI on society also raises important social and ethical questions. How societies adapt and integrate AI technologies will also play a significant role. If societies prioritize education systems that encourage critical thinking, problem solving, creativity, and emotional intelligence alongside the use of AI, the overall level of human intelligence could increase. Conversely, if AI leads to a devaluation of these skills in favor of purely technical skills, it could have a negative impact on the development of complete intelligence.

Published: July 2024

The intersection at Rawa Hingkik in Bogor Regency is a three-arm intersection without traffic signals. In 2021, a project aimed at enhancing traffic management at this intersection was implemented. The project aimed to alleviate congestion at intersections, utilizing the 1997 Indonesian Highway Capacity Manual (MKJI 1997) for analysis, including intersection capacity, queue length, and delays. Data collection primarily focused on the Rawa Hingkik Intersection, followed by processing and evaluation. Analysis results indicated that prior to the improvement project, the intersection experienced high congestion, with a Degree of Saturation (DS) of 1.73 and various delays, resulting in a Level of Service (LOS) of F. However, post-improvement, the congestion significantly decreased, as evidenced by a reduced DS of 1.17 and improved LOS to B. Thus, it can be concluded that the traffic management enhancement at Rawa Hingkik intersection successfully mitigated congestion.

This paper analyzes the status of the injured party in the criminal proceedings of the Republic of Serbia. The discourse is divided into three sections. The first section discusses the rights afforded to a person injured by the commission of a criminal offense, including a critique of certain legal solutions and the presentation of a de lege ferenda proposal. The second section is dedicated to the relatively clear obligations of the injured party within criminal proceedings. The paper concludes with reflections and proposals aimed at enhancing the role of the injured party beyond their current status and improving their position within criminal proceedings.
Sealing of roof penetrations during building construction
Authors: Lowe Scott. A.
Published: July 2024

For new building construction, roofs typically have a large number of penetrations that are blocked out before the roof deck is poured. After the roof is poured, these penetrations need to be sealed temporarily to prevent rainwater entering the building. Unfortunately, it is all too common that the ad-hoc approach to sealing these openings results in penetrations left open to the elements. This results in water pouring into the building every time it rains. This paper shows examples of unsealed roof penetrations and of the subsequent damage caused. The penetrations relate to the work of several different trades, who may not place any priority on this issue. It is therefore suggested that this is a problem that the construction management team has to take charge of. At the very least, the roof should be inspected before impending rain events.

Published: July 2024

The bacteria, one of the most pervasive microorganisms globally, are involved in a myriad of roles in the lentic ecosystem. Consequently, the aquatic environment plays a crucial role in fostering soil health and nutrient levels. The present investigation focuses on potential microorganisms capable of decolorizing synthetic dyes, sourced from aquatic environments. The findings reveal that when cultured in broth containing Congo red dyes in varying doses (100, 200, 300, 400, 500, and 800 mg/L), the decolorization efficiency of bacterium TBSP1 was recorded at 99.8%, 99.6%, 95%, 87.8%, and 79.67%, respectively. Similarly, TBSP2 demonstrated an efficiency of 100%, 99%, 98%, 95%, 88.04%, 53.27%, and 65% for Congo red dye after 6 days post-inoculation at concentrations of 100, 200, 300, 400, 500, and 800 mg/L, respectively. At 3-day post-inoculation, TBSP1 and TBSP2 immobilized cells show case decolorization efficiencies of 96.04%, 93.73%, and 88.64% with low concentrations of dyes with Congo red, both with and without immobilization. Furthermore, due to changes in functional group by bacterial enzymatic activity, decolorization efficiency was observed with TBSP1 and TBSP2 at 12, 24, 48, and 72 h post-inoculation. .

Virtual Jumu’ah Prayer: Debates, Challenges, and Scholar Perspectives Amidst The COVID-19 Pandemic
Authors: Achmad Adang Darmawan , Qotadah Hudzaifah Achmad
Published: July 2024

Jumu’ah, regarded as the pinnacle of the weekly Islamic worship, mandates ritual purification, donning immaculate attire, and congregating at the mosque for Friday Prayer. However, the onset of the COVID-19 pandemic has necessitated adaptations in religious practices, compelling Muslims to pivot towards virtual modes of worship in compliance with directives issued by governmental and health authorities aimed at mitigating the transmission of the coronavirus. The transition to virtual or online prayer has sparked considerable theological discourse and scrutiny in light of the pandemic's challenges. Consequently, this research aims to rigorously examine the doctrinal perspectives on virtual Friday prayer. Employing a comprehensive qualitative methodology, this study undertakes a detailed descriptive analysis. Findings underscore ongoing theological debates among Muslim scholars worldwide, including in Indonesia, where divergent viewpoints exist regarding the permissibility of participating in Jumu’ah prayer remotely via broadcast or live streaming under any theological school (madhhab). Critics argue against virtual congregational prayer due to logistical challenges posed by physical distancing, asserting that the spatial and communal integrity essential to Islamic worship may be compromised. Conversely, proponents advocate for a pragmatic approach, invoking the principle of maslahat (public interest) to safeguard the continuity of Friday prayers amidst unprecedented circumstances. In conclusion, this study contributes to the scholarly discourse on contemporary Islamic jurisprudence by elucidating the multifaceted debates surrounding virtual Jumu’ah prayer during the COVID-19 pandemic, reflecting diverse interpretations and applications of Islamic law in response to evolving global challenges.
A TEORIA DOS REGISTROS DE REPRESENTAÇÃO SEMIÓTICA NO ENSINO DE FRAÇÃO EM LIVROS DIDÁTICOS E A MOBILIZAÇÃO PARA O DESENVOLVIMENTO DO LETRAMENTO MATEMÁTICO: UM OLHAR PARA TESES E DISSERTAÇÕES
Authors: Pinheiro Gisele de Souza , Lopes Thiago Beirigo
Published: July 2024

Esta pesquisa tem como objetivo analisar as produções sobre a Teoria dos Registros de Representação Semiótica (TRRS) no ensino de fração em livros didáticos, com vistas ao desenvolvimento do Letramento Matemático. Para isso, foi realizada a busca de produções científicas no repositório digital do Catálogo de Teses e Dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), separadas em três buscas de agrupamento, dois a dois, dos termos: ‘Registros de Representação Semiótica’, ‘Letramento Matemático’ e ‘livro didático’. Esta pesquisa qualitativa caracteriza-se, quanto aos procedimentos, como pesquisa bibliográfica, do tipo Estado do Conhecimento, e tem como aporte teórico a Teoria dos Registros de Representação Semiótica de Raymond Duval, além das concepções do Letramento Matemático. Para a identificação, categorização e análise, o Estado do Conhecimento foi dividido em quatro etapas, conforme explicitado por Kohls-Santos e Morosini (2021), incluindo categorização com o auxílio do software IRaMuTeQ. As análises apontaram que, apesar de serem poucas as publicações que abordam a relação entre Letramento Matemático e TRRS no ensino de fração em livros didáticos, elas revelam a preocupação com a abordagem dos significados de fração e a efetiva utilização dos registros de representação semiótica para a aprendizagem dos estudantes. Destacam também a importância que o livro didático tem nesse processo, como importante recurso pedagógico de auxílio para os professores.
The Ineffective Use of Inhalers in Chronic Obstructive Pulmonary Disease
Authors: Graham L.E.
Published: July 2024

Chronic Obstructive Pulmonary Disease (COPD) is the most common adult respiratory disease in Nepal. It is disabling condition and requires the use of inhaled and/or oral medications for stabilisation. Inhaled medications are preferable to oral medications because of their superior effect and lack of side effects. Spacer device are also available; these reduce the need for inhaler co-ordination.The aims of this study were to determine a) the percentage of patients with COPD attending the medical clinic who use inhaled medication. b) the skill level of patients regarding inha ler technique. c) the benefit of inhaler technique counselling for improving patient skill level.In this prospective randomised study we interviewed 95 patients with COPD over a4-month period. Thirty-three patients were regularly using inhalers, but 100% had anunsatisfactory inhaler technique. Only one patient used a spacer device.Thirty percent of patients claimed that they had never been shown how to use theinhaler.Subsequent demonstration of inhaler technique by a doctor improved skill level in85% of patients but resulted in a satisfactory inhaler technique score for only onepatient.Although this is a small study, it is probably representative of the patient populationwith COPD who attend our clinics. Patients, especially the elderly, have considerabledifficulty activating and using MDI – despite demonstration. Doctors infrequentlyprescribe spacers and the cost of these excludes many patients from using them.

Despite various signs in stupor are associated with different nosological groups, diagnostic significance of the associations are yet not clear. Present work was undertaken with the aim to find out any relation of stupor/stupor-like states with variousobjective cross-sectional clinical findings. A total of 24 patients presented in stupor and stupor-like states admitted in the psychiatry ward of a tertiary level hospital in Nepal were included in the study. Only 16 out of 36 items in Modified Rogers Scale and 17 out of 32 items in Present State Examination (sections 18-20) were scored. Eight items were common between to rating scales. Factor analysis of thus obtained 25 items revealed 10 factors with eigenvalue more than one. Only three factors were suggestive but none were diagnostic of any of nosological groups. The cross-sectional clinic findings do not seem to have definite diagnostic significance and we thus support a holistic clinical evaluation of patients in stupor to reach a diagnosis

Published: July 2024

Objective: This prospective study was done to assess the level of preoperative hearing impairment in different sites of pars tensa perforation in patients with chronic suppurative otitis media (CSOM) tubo-tympanic type undergoing myringoplasty.
Materials and Methods: A total of 50 patients were recruited from the outpatient Department of Otorhinolaryngology and Head and Neck Surgery from June 2003 to May 2004. Cases of CSOM tubo-tympanic type with dry central perforation, with conductive type of hearing loss were subjected to myringoplasty. Preoperative audiometric evaluations were done. Just prior to operation, examination under microscope was performed. Exact site of perforation was noted. During operation, those found to have ossicular discontinuity or fixation were excluded from this study.
Results: It was observed that the greatest hearing loss was found in big central (45dB) and posterior central (43dB); whereas least in those of anterior central (31dB) and central malleolar (34dB) perforations. The average hearing loss at 500Hz, 1000Hz and 2000Hz was 46.40 dB, 30.90 dB and 31.9 dB respectively. This showed that the hearing loss is maximum at the lowest frequencies and minimum as the frequencies increase.
Conclusion: This study shows that the posterior-central perforations cause more hearing loss than anterior-central ones. The hearing loss is maximum at the lowest frequencies and minimum as the frequencies increase.
