Our objective was to analyze longitudinal cellular and humoral immune responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination in people with multiple sclerosis (pwMS) on B-cell depleting treatment (BCDT) compared to pwMS without immunotherapy. We further evaluated the impact of COVID-19 infection and vaccination timing. PwMS (n = 439) on BCDT (ocrelizumab, rituximab, ofatumumab) or without immunotherapy were recruited for this prospective cohort study between June 2021 and June 2022. SARS-CoV-2 spike-specific antibodies and interferon-γ release of CD4 and CD8 T-cells upon stimulation with spike protein peptide pools were analyzed at different timepoints (after primary vaccination, 3 and 6 months after primary vaccination, after booster vaccination, 3 months after booster). Humoral response to SARS-CoV-2 was consistently lower whereas T-cell response was higher in patients with BCDT compared to controls. Cellular and humoral responses decreased over time after primary vaccination and increased again upon booster vaccination, with significantly higher antibody titers after booster than after primary vaccination in both untreated and B-cell-depleted pwMS. COVID-19 infection further led to a significant increase in SARS-CoV-2-specific responses. Despite attenuated B-cell responses, a third vaccination for patients with BCDT seems recommendable, since at least partial protection can be expected from the strong T-cell response. Moreover, our data show that an assessment of T-cell responses may be helpful in B-cell-depleted patients to evaluate the efficacy of SARS-CoV-2 vaccination.

This study was conducted to confirm variation in bovine viral diarrhea virus (BVDV) antibody levels transferred to calves from their mother’s colostrum after vaccination of late-gestational cows. Blood samples were drawn from 60 pregnant cows that had been vaccinated more than one year and less than two years previously. The samples were collected six weeks prior to the expected date of delivery. After sample collection, the cows were divided into two groups of 30. One group received 2 mL of BVDV vaccine, and a control group received 2 mL of phosphate-buffered saline (PBS). Blood was collected from the cows three weeks post-administration. Additional blood samples were taken from calves at 1, 4, 8, 12, 16, and 20 weeks after birth. The serum was separated from the collected blood, and BVDV antibody changes were confirmed by enzyme-linked immunosorbent assays. BVDV antibody levels were higher from 8 to 20 weeks of age in calves born to late-gestational BVDV-vaccinated cows than in calves born to control cows (p < 0.0083). Further analysis confirmed a slow decline in BVDV maternal antibodies in calves born to pregnant cows that produced high levels of BVDV antibodies following pre-calving BVDV vaccination. These results suggest that BVDV vaccination of cattle in late pregnancy may help to extend the duration of protection against BVDV infection in newborn calves.
Numerical Study on Fish Collection and Transportation Facility with Water Temperature Compensation

Published: September 2023

Fish collection and transportation facilities have been widely constructed as man-made passages that allow fish to bypass dams. These facilities usually provide proper conditions that attract and gather fish inside, and then transport them upstream over the dam. A novel design that includes water temperature compensation was presented, and the velocity, temperature distribution, and turbulent kinetic energy inside the fish collecting channel were studied using numerical tools. The facility mixes the warm cooling water from the electrical transformer with the tailwater in order to reduce the negative ecological effect of the low-temperature discharge. It can operate under a 2 m water level range in the tailrace channel. The numerical results show that the temperature inside the fish collecting channel increased by about 2 °C and settled within the suitable range of the target fish species. The water body maintained a relatively uniform and steady temperature. The velocity and the turbulence kinetic energy (TKE) field near the fish entrance were distinct from those of the background and were beneficial for fish migration. This study could potentially motivate ecological engineers to mitigate the negative impacts of low-temperature tailwater from hydropower plants when designing fish collection and transportation facilities.

Published: September 2023

Solute transport in aquifers is usually controlled by dynamic changes in groundwater tables. The influence mechanism of surface hydrological processes, especially precipitation, on solute transport under different water table conditions has not been studied much. Prior to the direct application of the existing solute transport mechanisms and models to the solute transport process, the following questions need to be addressed: (1) Do surface hydrological conditions (e.g., precipitation) cause changes in the gradient of the water table within a specific region? (2) If the gradient of the water table does change, how does the change influence solute transport and distribution in the aquifer? The objective of this study is to investigate how precipitation impacts the gradient of water table and to analyze how the solute transport is influenced by the change in the gradient of water table. To achieve this, we employed an analytical solute transport model for the time-varying gradient of a water table through continuous multipoint monitoring of the groundwater table data. Further, the model was applied to indoor experiments to simulate solute transport with and without precipitation. Finally, the mechanism of solute transport in the aquifer under the changing gradient of the water table was analyzed using mathematical and physical models, and the modeling results were compared with those from a numerical model to analyze the modeling reliability. The results showed that precipitation changed the previously stable gradient of the water table, which further altered the gradient of the water table and the transport path of the tracer. The tracer transport direction was primarily controlled by the flow direction in the sandy aquifer trough without precipitation. However, the route of the tracer transport was consistent with the direction of the change in the water table gradient due to precipitation. The small discrepancy between the results from the analytical and numerical models indicates that the model employed in this study is reliable.
Exploring the Effect of Meteorological Factors on Predicting Hourly Water Levels Based on CEEMDAN and LSTM
Authors: Yan Zihuang , Lu Xianghui , Wu Lifeng
Published: September 2023

The magnitude of tidal energy depends on changes in ocean water levels, and by accurately predicting water level changes, tidal power plants can be effectively helped to plan and optimize the timing of power generation to maximize energy harvesting efficiency. The time-dependent nature of water level changes results in water level data being of the time-series type and is essential for both short- and long-term forecasting. Real-time water level information is essential for studying tidal power, and the National Oceanic and Atmospheric Administration (NOAA) has real-time water level information, making the NOAA data useful for such studies. In this paper, long short-term memory (LSTM) and its variants, stack long short-term memory (StackLSTM) and bi-directional long short-term memory (BiLSTM), are used to predict water levels at three sites and compared with classical machine learning algorithms, e.g., support vector machine (SVM), random forest (RF), extreme gradient boosting (XGBoost), and light gradient boosting machine (LightGBM). This study aims to investigate the effects of wind speed (WS), wind direction (WD), gusts (WG), air temperature (AT), and atmospheric pressure (Baro) on predicting hourly water levels (WL). The results show that the highest coefficient of determination (R2) was obtained at all meteorological factors when used as inputs, except at the La Jolla site. (Burlington station (R2) = 0.721, Kahului station (R2) = 0.852). In the final part of this article, the complete ensemble empirical mode decomposition adaptive noise (CEEMDAN) algorithm was introduced into various models, and the results showed a significant improvement in predicting water levels at each site. Among them, the CEEMDAN-BiLSTM algorithm performed the best, with an average RMSE of 0.0759 mh−1 for the prediction of three sites. This indicates that applying the CEEMDAN algorithm to deep learning has a more stable predictive performance for water level forecasting in different regions.

Published: September 2023

Dyes are the most carcinogenic organic compounds that are discarded by most of the textile industries without any prior treatment, which is harmful for the environment. This study aims to develop a bentonite-clay/carbon-nanotube (CNT)-based adsorbent to treat textile wastewater for water sustainability. The preliminary and post-characterization of adsorbent involves scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and Brunauer–Emmett–Teller (BET) and energy-dispersive X-ray (EDX) analysis to determine the changes in surface morphology, functional group, and surface area of the adsorbent. Linear and nonlinear isotherms and kinetic studies were performed to explore the sorption mechanism. The results show that the nonlinear form of the Langmuir isotherm best fits adsorption with a qmax of 550 mg/g. The adsorption followed the nonlinear pseudo-first-order kinetics, favoring chemisorption with R2 ≈ 1 and X2 = 0.22. Maximum dye removal (89.9%) was achieved under the optimum conditions of pH 3, an adsorbent dose of 100 mg, and a contact time of 120 min, with an initial COD concentration of 1140 mgL−1. This study has demonstrated the successful application of a bentonite-clay/CNT-based adsorbent on textile wastewater treatment.
Changes in Snow Surface Albedo and Radiative Forcing in the Chilean Central Andes Measured by In Situ and Remote Sensing Data

Published: September 2023

Snow-covered regions are the main source of reflection of incident shortwave radiation on the Earth’s surface. The deposition of light-absorbing particles on these regions increases the capacity of snow to absorb radiation and decreases surface snow albedo, which intensifies the radiative forcing, leading to accelerated snowmelt and modifications of the hydrologic cycle. In this work, the changes in surface snow albedo and radiative forcing were investigated, induced by light-absorbing particles in the Upper Aconcagua River Basin (Chilean Central Andes) using remote sensing satellite data (MODIS), in situ spectral snow albedo measurements, and the incident shortwave radiation during the austral winter months (May to August) for the 2004–2016 period. To estimate the changes in snow albedo and radiative forcing, two spectral ranges were defined: (i) an enclosed range between 841 and 876 nm, which isolates the effects of black carbon, an important light-absorbing particle derived from anthropogenic activities, and (ii) a broadband range between 300 and 2500 nm. The results indicate that percent variations in snow albedo in the enclosed range are higher than in the broadband range, regardless of the total amount of radiation received, which may be attributed to the presence of light-absorbing particles, as these particles have a greater impact on surface snow albedo at wavelengths in the enclosed band than in the broadband band.

ESKAPE bacteria represent a group of opportunistic bacterial pathogens that display widespread antimicrobial resistance, including resistance to the last-line antibiotics, thereby posing a significant clinical implication globally. Anthropogenic activities, such as wastewater from hospitals, livestock farms, crop fields, and wastewater treatment plants, contribute to the dissemination of antimicrobial-resistant bacterial pathogens into the environment. Surface water sources, including river waters, act as critical points of discharge for wastewater, pollutants, antibiotic-resistant bacteria (ARB), and antibiotic-resistant genes (ARG). These environmental factors, along with others, facilitate the dissemination and survival of ARBs, as well as promote the exchange of ARGs. Therefore, it is crucial to comprehend the current environmental landscape concerning the prevalence and persistence of resistant bacteria, particularly those belonging to the ESKAPE group. This review aims to provide a comprehensive overview of the current dissemination and characterization of ESKAPE bacteria in surface water and wastewater sources.

Examination of the interaction effect of stress in the relationship between value congruence and intrinsic work motivation
Authors: Gaudet Madeleine , Lajoie Denis
Published: September 2023

The purpose of this study is to observe whether workplace stress could act as a moderator in the relationship between value congruence and intrinsic motivation. According to theoretical perspectives, stress-related psychological demands should attenuate the positive effect of value congruence-related psychological resources on motivation. 294 subjects participated in this study by completing questionnaires on our three variables of interest on the Prolific platform. The results did not show an interaction effect by stress on the relationship between value congruence and intrinsic motivation. Moreover, an equivalence test indicated that the moderation effect size was too small to influence the practical level. In conclusion, the hypothesis postulating a moderating link of stress on the relationship between value congruence and intrinsic motivation was not confirmed.
Views of veterinary faculty students on the concept of Artificial Intelligence and its use in Veterinary Medicine practices: An example of Ankara University Faculty of Veterinary Medicine
Authors: Yerlikaya Nigar , Küçükaslan Özgül
Published: September 2023

The study was carried out to determine the knowledge levels of the students of Ankara University Faculty of Veterinary Medicine, on the concept of artificial intelligence and its use in veterinary practices. For this purpose, an online questionnaire was applied to a total of 529 students in the study, covering all grades of the faculty. The questionnaire consists of two parts. In the first part, there are 10 questions including demographics, knowledge about the concept of artificial intelligence, etc. The second part consists of 26 5-point Likert-type questions to determine students' thoughts on artificial intelligence applications. Data were analyzed using statistical tests. Consequently, the students participating in the study are partially knowledgeable about artificial intelligence (52.9%). They know the importance of following the developments in artificial intelligence for the profession (45.2%). They think that artificial intelligence applications will improve their professional skills (53.5%). They have the opinion that a robot cannot replace a veterinary surgeon (36.7%) and artificial intelligence cannot cause unemployment in veterinary medicine in the future (35.3%). In addition, they believe that artificial intelligence can cause ethical problems (39.3%) and that applications made with this technology should be developed in an ethical sense (42.4%). As a result, while the students think that artificial intelligence will have positive effects in the field of veterinary medicine, they also think that artificial intelligence can bring negative ethical implications. It can be concluded that including elective courses on artificial intelligence applications in veterinary faculties and conducting further research on the subject would be beneficial.
Prise en compte et gestion de contraintes : une étude dans la résolution d’un problème créatif de conception
Authors: Chevalier Aline , Bonnardel Nathalie
Published: September 2023

Cette étude vise à déterminer l’effet du niveau de précision du cahier des charges à satisfaire et du niveau d’expertise des concepteurs sur la mobilisation de contraintes liées au commanditaire pour résoudre un problème créatif de conception d’un site internet. Pour cela, des concepteurs professionnels et débutants doivent élaborer la première maquette d’un site en fonction soit d’un cahier des charges comportant de nombreuses contraintes, soit d’un cahier des charges ne comportant aucune contrainte. Les résultats montrent que les concepteurs professionnels infèrent plus de contraintes que les novices, quel que soit le cahier des charges. En outre, les concepteurs professionnels et débutants n’adoptent pas la même stratégie de gestion de contraintes. Les professionnels adoptent principalement une «stratégie de report », où certaines contraintes mobilisées sont mises de côté pour y revenir ultérieurement. Les concepteurs débutants adoptent principalement une «stratégie anticipative », où les contraintes mobilisées sont immédiatement respectées.
La décennie 1989-1998 dans la psychologie espagnole : analyse de l'évolution de la psychologie professionnelle en Espagne
Authors: Santolaya Ochando Francisco , Berdullas Temes Manuel , Fernández Hermida José Ramón
Published: September 2023

Dans cet article, une vue générale de l’évolution et de la situation actuelle de la psychologie professionnelle en Espagne est présentée. D’un point de vue historique, depuis les années soixante-dix, la profession de psychologue en Espagne a progressé de façon importante tant en qualité qu’en quantité. Il y a de nombreuses raisons différentes de ce développement, bien que, dans cet article, nous en soulignions deux : l’introduction du diplôme de psychologie et le développement d’une identité professionnelle due à l’influence d’une organisation telle que le Colegio oficial de psicólogos (COP, également dénommé Association espagnole de psychologie). Notre description de la situation actuelle est fondée sur l’analyse des résultats de 6 765 réponses à approximativement 28 000 questionnaires qui avaient été envoyés aux membres du Collège. En général, ces résultats révèlent une profession pratiquée, de façon prédominante, par des femmes jeunes (moyenne d’âge : 36 ans), travaillant, de préférence dans le secteur clinique, dont l’orientation théorique est principalement comportementale, localisées en majorité en zone urbaine et travaillant essentiellement en pratique privée. Les principaux domaines professionnels actuels, dans notre pays, sont analysés en détail, selon les critères suivants : type de lieu où le professionnel travaille, secteurs d’intervention et formation requise pour la pratique professionnelle. Pour finir, quelques réflexions sur la défense de la profession font l’objet de commentaires, avec des propositions pour la formation et les stratégies d’accréditation comme meilleur moyen de faire face aux problèmes croissant de l’entrée dans la profession de gens non qualifiés.
Episodes interdiscursifs maître-élève(s) et construction de connaissances dans un dispositif d’enseignement-apprentissage de type socio-constructiviste en CM1
Authors: Roux Jean-Paul
Published: September 2023

Prenant appui sur la théorie de l’analyse interlocutoire, le présent travail étudie les confrontations socio-cognitives médiatisées par les signes du langage entre un professeur et ses élèves dans une situation de guidage et de remédiation. Il apparaît que ce sont les actes de langage échangés au cours des transactions ayant pour objet la négociation de sens qui sont à l’origine, chez les élèves, d’un travail d’autocontrôle cognitif et métacognitif constructeur, grâce à l’utilisation de signes-outils spécifiques favorisant la construction de l’intersubjectivité. On peut en déduire que c’est l’élaboration et l’appropriation in situ d’outils sémiotiques qui permet la construction de modes de traitement décontextualisés, généralisables et transférables.
Fonctionnements et développements cognitifs : une approche pluraliste de la question
Authors: Lautrey Jacques , Caroff Xavier
Published: September 2023

Les relations entre fonctionnement et développement cognitifs sont discutées à propos de la notion de conservation. Deux processus sont supposés être activés simultanément dans la situation de conservation : 1 ° la centration sur une des dimensions de la transformation et 2° l’inférence fondée sur l’identité de l’objet. L'hypothèse selon laquelle l’interaction de ces deux processus est une des sources du développement de la notion de conservation est testée par une expérience d’apprentissage conduite avec 1 1 6 enfants non conservants (âge moyen 5 ;6). Le plan d’expérience croise les deux processus (celui utilisé préférentiellement par l’enfant avec celui entraîné par la situation d’apprentissage). Les résultats sont compatibles avec l’hypothèse selon laquelle le processus d’inférence fondé sur l’identité joue un rôle de guidage dans le développement du processus de traitement des dimensions de la transformation.
Interactions sociales et appropriation de stratégies par l’enfant pour résoudre un problème : quelles méthodes ?
Authors: Tartas Valérie , Perret-Clermont Anne Nelly , Marro Pascale , Grossen Michèle
Published: September 2023

Cette recherche s’inscrit dans une série de travaux recourant à une méthodologie alliant l’approche clinique piagétienne, expérimentale dans des situations différentes, et vygots-kienne, afin de mettre en évidence les processus par lesquels l’appropriation de stratégies par l’enfant sera possible par l’observation attentive de son histoire d’apprentissage et afin de comprendre un peu mieux les conditions de la mobilisation ultérieure de ces apprentissages. La méthode utilisée consiste à placer les enfants dans trois ou quatre contextes différents, à observer leurs interactions et leurs conduites cognitives, notamment en fonction de leur niveau d’expertise initial par rapport à une tâche donnée : une phase I de prétest, permettant d’apprécier le niveau initial de chaque enfant en interaction avec un adulte testeur, les enfants sont alors classés en «novices», «experts spontanés», une phase II de formation (selon des modalités qui varient) avec un adulte pour une partie des enfants novices qui deviendront ainsi des «experts formés», puis une phase III d’interaction entre «novice» et «expert» (soit spontané soit formé) et, enfin, une dernière phase IV «post-test», identique au pré-test.

Les focus groups sont des espaces de communication qui nous permettent d’observer des interactions, des souvenirs et des représentations en cours d’élaboration. Ils correspondent aux exigences méthodologiques de deux champs de recherche qui ont une filiation épistémologique forte, les représentations et la mémoire sociales. Notre article s’inscrit dans cette problématique et met en évidence la fécondité de cette articulation à travers une étude de terrain centrée sur un conflit symbolique dans les Balkans entre la Grèce et la République de Macédoine. «L’affaire macédonienne» met en jeu l’histoire, la mémoire et les exigences conventionnelles du présent dans un processus de défense des significations imaginaires nationales.
Les destins de l’analogie

Published: September 2023

Partant du constat d’une réhabilitation de la notion d’analogie et d’un renouveau des recherches à son sujet, les auteurs proposent une réflexion en trois temps. En un premier temps, une étude des usages récents de la notion permet de mettre en évidence comment ceux-ci témoignent à la fois d’une inflexion de nos conceptions du psychisme et d’une résurgence de problématiques anciennes. En un deuxième temps, une exploration des domaines de recherche (raisonnement analogique, représentations analogiques, messages analogiques) soutient des considérations épistémologiques sur les possibles rencontres entre la psychologie clinique freudienne, la psychologie cognitive et la sémiologie. Enfin les auteurs définissent un cadre théorique et méthodologique indispensable à la détermination de recherches cliniques sur le fonctionnement mental analogique. Une réflexion sur les rapports entre les processus analogiques et l’imaginaire parcourt l’ensemble du travail.
Effets de la communication par réseaux informatiques versus en face-à-face sur la représentation réciproque des négociateurs

Une expérience est menée pour examiner les effets de deux supports de communication médiatisée par réseaux d’ordinateurs (CMO) vs face-à-face (FàF) sur la représentation développée par les négociateurs envers leurs adversaires, ainsi que sur leur prise de décision commune, dans une situation de négociation au niveau de laquelle intervient un médiateur. Il est supposé, d’une part, que les négociateurs se percevront réciproquement plus négativement en mode de communication médiatisé par ordinateurs qu’en mode face-à-face. Il est supposé, d’autre part, que l’issue de la négociation dépendra moins du statut social du médiateur en mode CMO qu’en mode FàF. Globalement, les résultats obtenus valident ces hypothèses.
Intellectual Capital for Enhancing Sustainable Industrialization: Towards the Sustainable Development Goal (SDG) 9
Authors: Cabrita Maria , Užienė Lina , Garcia-Perez Alexeis , Viedma Jose Maria
Published: September 2023

Intellectual Capital (IC) has played a major role in driving growth, competitiveness, and sustainability over decades, improving people’s well-being and the economic performance of businesses. At the same time, the United Nation’s Sustainable Development Goals (SDGs) have emerged as an integrated approach to sustainable development principles of people, planet, prosperity, peace, and partnership, which represent one of the most urgent challenges in our times. The industrial sector is particularly challenged to adopt a sustainable approach to solving development issues by addressing the SDGs. Sustainable Development Goal 9 (SDG 9) is built on three interconnected pillars: infrastructure, industry, and innovation, all of which are strongly interconnected, sharing the common mission of achieving socially inclusive and environmentally sustainable economic development. By adopting SDG 9 and its related targets, the global community can benefit from an industrial development that is inclusive and sustainable, with an impact on all other SDGs. From a strategic perspective, IC is predominantly studied as a bundle of intangibles that creates value, thus embodying a set of resources that are decisive in sustaining competitive advantage, which is necessary for sustainability and for ensuring people’s well-being and economic growth, in line with SDGs. Despite an increasing number of studies exploring the links between IC and sustainability, a major gap emerges in what concerns the influence of IC on achieving SDGs in specific or interconnected goals. Based on the relevant literature, the aim of this paper is to explore how the characteristics of the IC can foster the 2030 Agenda for Sustainable Development, specifically, the sustainable and innovative development of organizations by adopting Goal 9 and its targets. This paper contributes to the literature on IC as a driver for SDGs. In more detail, it opens some avenues for future research on strengthening capabilities to solve development challenges, involving different actors, stakeholders, sectors, and regions.
Future Nostalgia: Breeds, Deeds, and Otherworldly Ruins
Authors:   University of Tennessee, Knoxville, Abudayyeh Rana
Published: September 2023

Building and construction are responsible for about 40% of carbon emissions globally. This sobering reality raises the question: do we need to build new? The reactivation of dormant existing structures was the main focus of an inter-disciplinary vertical design studio that included third-year Architecture and fourth-year Interior Architecture students. The studio addressed the synthesis and propagation of new strategies to revitalize decommissioned parts of our built environment generating speculative narratives for future cities in partnership with Gensler, one of the world-leading design practices. This collaboration demarked a unique overlap between pedagogy and practice, bringing real-world climate issues into academia for collective problem-solving. This partnership emerged from Gensler’s involvement in the shaping of existing and future cities. The firm is actively lever¬aging mobility through design to create multimodal, vibrant settings. Throughout the semester, students interacted with designers from Gensler to explore multimodal thinking, cli¬mate sensitivity, and the transformative impact of adaptive reuse in the urban environment. The partnership encouraged human-centric design sensibilities, cognizant that human experience is ultimately at the center of any design problem. Together, students and professionals pursued design solutions capable of adapting to a changing world and catering to future cities. Future cities rely on collaborative networks and shared platforms, asserting a more collective societal presence. This shift necessitates new multifunctional urban centers. As such, this collaborative studio engaged the design of multimodal transportation hubs grafted in the context of four inactive building types. The four-building typologies were the indoor mall, the office building, the parking structure, and the abandoned cultural icon. The selected buildings were sited in different cities. Each combination (city and building type) offered distinct challenges and opportunities for intervention within the urban fabric. Collectively, the four locations informed an agenda for resilient future cities, actively responding to the pressing realities of climate change while catering to shifting socio-economic parameters.
Business as Unusual: Pedagogical Experiments at ESALA

Published: September 2023

The relationship between design, material processes and their application has been a consistent theme in the teaching and research at the Edinburgh School of Architecture and Landscape Architecture (ESALA), at the University of Edinburgh. This work was strengthened and consolidated with the formation of the Architectural Research Workshop (ARW), and with its increased ability to produce large-scale prototypes, and has intensified in recent years as we rethink architectural pedagogy in response to the impacts of climate breakdown and its associated injustices. This paper presents a selection of courses and pedagogies, developed by academic staff at ESALA, that seek to take the environmental crisis as an opportunity to prototype novel construction materials, fabrication protocols, and architectural design methods, foregrounding an open-ended design process that privileges encounters with pre-existing materials over the architect’s own aspirations and ideas. In three teaching projects, and across several years and programmes, we outline an approach that emphasizes reuse and repurposing practices in relation to making (material processes and affordances) and making visible (diverting material flows; reclaiming values and valuing protocols). The three projects discussed—the MSc program “Material Practice,” and two studio options within the BA/MA under-graduate Architecture Honors Program (a third-year unit entitled “Radical Coauthorship,” and a fourth-year one entitled “No Blank Slate”)—encourage a direct engagement with material histories and ecologies (surveys and classifications) and fabrication processes (experiments and full-scale prototyping), demonstrating a probabilistic approach that draws and develops designs from latent and embodied opportunities. These approaches demand that work be not (only) assessed according to final outputs (the considered object or building as desirable outcome), but in relation to the technical platforms, material flows, supply chains, and labor practices associated with them, questioning our very assumptions and biases in the adjudication of meaning, beauty, and value.

Published: September 2023

This paper explores University of Florida’s (UF) interdisciplinary coursework that centers student research on climate, policy, and design projects in coastal communities along the Atlantic and Gulf of Mexico. The evolution of interdisciplinary pedagogy is addressed through case studies of the Florida Climate Institute’s (FCI) Spring Field courses, the Envision Resilience Nantucket Challenge, and the Historic Preservation program’s Preservation Institute Nantucket (PIN) summer program. In the FCI Field courses, the focus has spanned ecological systems, built environment, and community engagement frameworks with UF faculty from design, planning, historic preservation, engineering, law, communications, and science, among other disciplines. PIN’s 2020 and 2021 research and coursework focused on the development of an adaptation and resilience strategy for a portion of Nantucket Town—one of the nation’s largest National Historic Landmark Districts. The Envision Resilience Nantucket Challenge, held in Spring 2021 and sponsored by ReMain Nantucket, was inspired by PIN and based in part on the Fieldcourse model. The case studies illustrate the evolving methodology of coursework at UF and the changing relationship between design and sciences/social science disciplines for the breadth of iterative, solution-based thinking for climate change. Concluding thoughts will explore the evolution of interdisciplinary design research at UF, potential gaps in disciplinary partnerships, and future project opportunities for addressing the critical complexities of climate change.

Perkembangan telekomunikasi di Indonesia yang sangat pesat membuat para pelaku usaha dibidang telekomunikasi bersaing dalam mendirikan menara telekomunikasi untuk memenuhi seluruh jaringan se-Indonesia. Sebagai akibat dari peningkatan kebutuhan jasa layanan telekomunikasi ini, tower dan Base Transceiver Station (BTS) semakin mempunyai jarak yang relatif dekat terutama pada daerah perkotaan, masalah lahan untuk pembangunan tower menjadi salah satu faktor kendala dalam peningkatan jaringan telekomunikasi, sehingga pembangunan tower di atas gedung (roof top) menjadi salah satu solusinya. Hal itu dapat mempengaruhi struktur bangunan di bawah tower tersebut. Dalam penelitian ini melakukan analisis struktur bangunan akibat penambahan beban pada tower. Pada proses analisa menggunakan bantuan program komputer ETABS V 9.7.4.  Hasil yang diperoleh adalah struktur bangunan utama tidak kuat menerima beban tambahan akibat kurangnya kapasitas geser. Luas tulangan perlu eksisting kolom yang dihasilkan adalah sebesar 1608 mm2. Kemudian, untuk luas tulangan perlu eksisting balok yang dihasilkan adalah sebesar 509 mm2 yang lebih kecil dibandingkan luas tulangan minimum. Pada eksiting balok terdapat kekurangan kapasitas geser yang dihasilkan. Akibat dari kekurangan kapasitas geser tersebut maka balok ekisting membutuhkan perkuatan. Perkuatan menggunakan Carbon Fiber Reinforced Polymer (CFRP). Analisis perkuatan balok tersebut menghasilkan balok dilapisi 1 lembar tipe Sika Carbodur S812

Penelitian ini menitikberatkan pada penambahan bahan pengisi (filler) yang didapatkan dari hasil pembakaran batu bara (abu terbang) pada PLTU Suralaya, Merak - Banten yang ditambahkan pada campuran agregat. Abu terbang batu bara merupakan limbah B3 menurut BAPEDAL maka dari itu untuk menanganinya digunakanlah sebagai bahan penambah pada penelitian aspal. Penelitian ini diharapkan dapat mengurangi dampak dari limbah pembakaran batu bara terhadap lingkungan. Penambahan bahan pengisi berupa abu terbang diharapkan menambah daya tahan lapis beton aspal yang disebabkan oleh cuaca atau beban kendaraan yang melintas. Penelitian ini bertujuan untuk mengetahui seberapa besar nilai karakteristik Marshall pada campuran beton aspal dengan menggunakan filler abu terbang batu bara. Penelitian ini menggunakan metode eksperimental yaitu dengan suatu percobaan untuk mendapatkan hasil, dengan demikian akan terlihat pemanfaatan filler abu terbang batu bara pada konstruksi beton aspal dengan variasi kadar filler 1%, 1,5%, dan 2% terhadap total campuran, kadar filler yang digunakan merupakan kadar filler yang telah ditentukan oleh Bina Marga (minimal 1% dan maksimal 2%). Penilitian dilakukan dengan membandingkan antara nilai dari karakteristik marshall campuran aspal normal dengan nilai karakteristik marshall dengan campuran aspal dengan penambahan abu terbang. Nilai karakeristik marshall untuk campuran aspal normal (KAO = 6,65%), campuran aspal dengan fly ash 1% (KAO = 4,90%), campuran aspal dengan fly ash 1,5% (KAO = 6,90%), campuran aspal dengan fly ash 2% (KAO = 6,90%) berturut-turut adalah : VIM(4,40%; 4,90%; 4,88% dan 4,90%), VMA(17,20%; 18,50%; 18% dan 18,20%), VFB(74%; 73%; 73,95 dan 73%), Stabilitas(1030 Kg; 1225 Kg; 1310 Kg dan 1430 Kg), Flow(3,40 mm; 2,90 mm; 3,20 mm dan 3,35 mm), MQ(308 Kg; 420 Kg; 410 Kg dan 430 Kg). Dari hasil karakteristik marshall pada kadar aspal optimum (KAO) mulai dari campuran aspal normal dan campuran aspal dengan penambahan fly ash seluruhnya memasuki spesifikasi yang telah ditentukan oleh Bina Marga 2010 Revisi III, maka penggunaan abu terbang batu bara dapat digunakan sebagai bahan pengisi untuk campuran laston lapis aus.

Interpretation of time-dependent current and resistance of HTS closed loop with superconducting joint considering flux creep
Authors: Takeda Yasuaki , Tsuchiya Yuji , Nishijima Gen
Published: September 2023

A low circuit resistance is required for a superconducting magnet operated in persistent mode using superconducting joints. We performed current decay measurements on a high-temperature superconducting (HTS) closed loop with a superconducting joint to evaluate the time dependence of the current and resistance. The results have been quantitatively explained by considering current sharing and flux creep. After the elapse of 105 s, current sharing was suppressed and a circuit resistance of less than 10−13 Ω was observed. The main finding is that joint resistance of an HTS closed loop is inversely proportional to time, contributing to low circuit resistance.

In this paper, we present the application of THz frequency-domain spectroscopy (THz-FDS) for determining the refractive index in an ambient environment. The signal phase is extracted from the periodically oscillated photocurrent by a magnitude normalization method. The proposed method is demonstrated using experimental data of polytetrafluoroethylene and α-lactose monohydrate as reference materials collected at a relative humidity of around 17.0% ± 2.0%. A detailed comparison to the existing algorithms, including the Hilbert transform and extreme points analysis, reveals the remarkable reliability of our proposed method. This study expands the characterization capabilities of THz-FDS and furthers the development of practical terahertz spectroscopy applications.
