The Words of the Righteous: The Death of Text and the Eternity of Stone
Authors: Picus Daniel
Published: November 2023

Abstract: This essay examines examples of the Oral Torah as a concrete, material phenomenon in late ancient rabbinic sources. The oral nature of oral Torah, both as an ideology and as a description of rabbinic textual practices, can elide some of the more evocative discussions of the nature of oral Torah. Previous discussions, such as Wollenberg (2019), have shown that the nature of the written Torah was often understood as unstable, changing, and mutable. This essay explores the other side of that equation, exploring discussions of oral Text as concrete, enduring, and unchanging. Two main examples are studied: the first from a passage in the Palestinian Talmud, and the second in a passage from the Babylonian Talmud. The Palestinian Talmud draws a dense network of connections between Torah scrolls, oral teachings, rabbinic sages, and the imagery of death and memorialization. The Babylonian Talmud similarly extends the value of rabbinic oral teaching into the World to Come, showing that while the associations between teaching, death, and eternal life manifest differently, they are still present in different rabbinic contexts. Taken together, these inscriptions of a concrete and material Oral Torah are fully realized in the body of the rabbinic sage. Other scholars have also shown that rabbinic sages become an embodiment of Torah: this essay examines the nature of rabbinic Torah, as discussed in rabbinic literature, to understand how that embodiment comes about.
What's (in) Your Bowl? Affordances of Incantation Bowls and their Use in Household Medicine
Authors: Amsler Monika
Published: November 2023

Abstract: This paper investigates the much-discussed Babylonian incantation bowls inspired by approaches from thing theory, such as the concept of affordance, and from cognitive studies, such as the distributed cognition hypothesis. For once, the material aspects of the bowl amulets and how people may have perceived them are the center of the analysis, not the texts or the images that are inscribed in them. Thus, I discuss the different and versatile affordances ("options for action") that the bowls offered people living in late antique Mesopotamia and what their physical presence may have meant in terms of the production of an emotional response (affect). The preparation process of an incantation bowl, including the choice of bowl, ink preparation, and the procuration of suitable texts, may be seen as a sign of affect and emotion on behalf of several household members. These practices are ultimately very comparable to physical caregiving, and production of a bowl amulet is thereby shown to be firmly grounded in late antique Babylonian household medicine.
Power and Praxis: Writing and Performance in Megillat Ahimaatz
Authors: Lieber Laura Suzanne
Published: November 2023

Abstract: In this essay, the text of Megillat Ahimaatz offers a window into compositional conventions, particularly around liturgy, as well as understandings of writing at a pivotal moment, and in a pivotal location: southern Italy (Apulia) in during the 9th–11th centuries. Both writing technologies and ritual performances (liturgical and magical) occupy prominent places in Megillat Ahimaatz, and the text seems to reflect a moment of great cognizance concerning the significance of writing and performative power and praxis, particularly among Jews but also in other communities, as well, as viewed through Jewish eyes. In this essay, I will (1) outline the text's general interest in writing, writers, performers, and performance, after which I will (2) present the specific varieties of writing and performance that occur in Megillat Ahimaatz. Finally, I will (3) examine the scroll's specific vocabulary for writing (texts and practices) and similarly, I will consider the way liturgical performance is described. These elements – narrative and lexical – when read together offer a window into at least one writer's understanding of his tradition at a pivotal crossroads in Jewish literary and liturgical history.
Diachrony and the Meaning of the Preposition בֵּין in Ancient Hebrew
Authors: Olivero Vladimir
Published: November 2023

Abstract: In this study I discuss the meaning of the preposition בֵּין from a diachronic perspective. While in Classical Biblical Hebrew (CBH) the preposition always means 'between' (with a single possible exception), from the time of the exile onwards it also takes on the meaning of 'among', probably under the influence of Aramaic and because of the disappearance of the composite preposition בְּקֶרֶב, which led to the reconfiguration of the use of prepositions such as בֵּין and בְּתוֹךְ. Both meanings ‘between’ and ‘among’ for the preposition בֵּין are known and reported in various lexica and reference grammars, yet they have never been considered and explained from a diachronic standpoint.
Love-Sickness and its Cure: A Reading of the Forty-Eighth Gate in Yehuda Al-Ḥarizi's Sefer Taḥkemoni
Authors: Einat-Nov Idit
Published: November 2023

Abstract: In his analysis of the forty-eighth gate in Yehuda Al-Ḥarizi's Sefer Taḥkemoni, David Simha Segal argued that this story "leaves open the possibility of multiple and even contradictory readings" (The Book of Taḥkemoni – Jewish Tales from Medieval Spain, 2001, p. 622) and proposed alternative interpretations of the story. Segal's argument regarding the nature of this story is in line with my basic assumption that at the core of some of the most fascinating rhymed Hebrew stories from the Middle Ages – in Al-Ḥarizi's Taḥkemoni, but also in the work of his predecessors, Shlomo Ibn Ṣaqbel and Yosef Ibn Zabara – lies uncertainty as a poetic principle. From this perspective, while addressing Segal's interpretation, in this article I propose additional interpretive insights.
The Description of Syntax in Medieval Hebrew Grammars
Authors: Wormser Yehonatan
Published: November 2023

Abstract: The study of Hebrew grammar by medieval Jewish scholars concentrates on phonological and morphological issues with much lower attention paid to Hebrew syntax. While the majority of medieval Hebrew grammars only contain scattered incidental remarks on topics related to the latter, some discuss syntactical themes at greater length. This paper examines the work of the four medieval grammarians who probably paid the most attention to Hebrew syntax – Abū Alfaraj Hārūn, Yonah ibn Janāḥ, Profiat Duran, and Abraham Debalmes. Surveying the relevant passages, it explores the primary issues they address and the insights they offer, hereby revealing with the nature and scope of medieval Jewish engagement with Hebrew syntax.

Published: November 2023

Deep neural networks usually process information through multiple hidden layers. However, most hardware reservoir computing recurrent networks only have one hidden reservoir layer, which significantly limits the capability of solving practical complex tasks. Here we show a deep photonic reservoir computing (PRC) architecture, which is constructed by cascading injection-locked semiconductor lasers. In particular, the connection between successive hidden layers is all optical, without any optical-electrical conversion or analog-digital conversion. The proof of concept PRC consisting of 4 hidden layers and a total of 320 interconnected neurons (80 neurons per layer) is demonstrated in experiment. The deep PRC is applied in solving the real-world problem of signal equalization in an optical fiber communication system. It is found that the deep PRC exhibits strong capability in compensating for the nonlinear impairment of optical fibers.

L-asparaginase (L-ASNase) is a versatile anticancer and acrylamide reduction enzyme predominantly used in medical and food industries. However, the high specificity of L-asparaginase formulations for glutamine, low thermostability, and blood clearance are the major disadvantages. Present study describes production, characterization, and applications of glutaminase free extracellular L-asparaginase from indigenous Bacillus halotolerans ASN9 isolated from soil sample. L-asparaginase production was optimized in M9 medium (containing 0.2% sucrose and 1% L-asparagine) that yielded maximum L-ASNase with a specific activity of 256 U mg-1 at pH 6 and 37°C. L-asparaginase was purified through acetone precipitation and Sephadex G-100 column, yielding 48.9 and 24% recovery, respectively. Enzyme kinetics revealed a Vmax of 466 mM min-1 and Km of 0.097 mM. Purified L-ASNase showed no activity against glutamine. The purified glutaminase free L-ASNase has a molecular mass of 60 kDa and an optimum specific activity of 3083 U mg-1 at pH 7 and 37°C. The enzyme retains its activity and stability over a wide range of pH and temperature, in the presence of selected protein inhibitors (SDS, β-mercaptoethanol), CoCl2, KCl, and NaCl. The enzyme also exhibited antioxidant activity against DPPH radical (IC50 value 70.7 μg mL-1) and anticancer activity against U87 human malignant glioma (IC50 55 μg mL-1) and Huh7 human hepatocellular carcinoma (IC50 37 μg mL-1) cell lines. Normal human embryonic kidney cells (HEK293) had greater than 80% cell viability with purified L-ASNase indicating its least cytotoxicity against normal cells. The present work identified potent glutaminase free L-ASNase from B. halotolerans ASN9 that performs well in a wide range of environmental conditions indicating its suitability for various commercial applications.

Published: November 2023

Trust is a key feature of social relationships. Common measures of trust, questionnaires and economic games, lack ecological validity. Hence, we sought to introduce an immersive, virtual reality (VR) measure for the behavioral assessment of trust across remote and in-person settings, building on the maze task of Hale et al. (2018). Our ‘Wayfinding Task’ consists of an interconnected urban environment for participants to navigate on the advice of two characters of differing trustworthiness. We present four studies implementing the Wayfinding Task in remote and in-person testing environments and comparing performance across head-mounted display (HMD)-based VR and desktop setups. In each study, the trustworthiness of two virtual characters was manipulated, through either a fact sheet providing trustworthiness information, or a behavior-based trustworthiness manipulation task termed the Door Game, based on Van der Biest et al., 2020. Participants then completed the Wayfinding Task. Overall, we found that participant behavior in the Wayfinding Task reflected the relative trustworthiness of the two characters; in particular, the trustworthy character was approached more often for advice, reflecting data from our Door Game. We found mostly null results for our novel outcome measure, interpersonal distance. Remote testing successfully achieved these effects. While HMD-based VR and desktop setups both showed these effects, there was a stronger effect of trustworthiness in the HMD VR version of the task. These results have implications for the measurement of trust in behavioral settings and the use of remote and VR-based testing in social experiments.

Published: November 2023

Purpose

Angiopoietin (Ang) 2 is released from vascular endothelial cells by the stimulation of vascular endothelial growth factor (VEGF)A. Ang2 increases the expression of leukocyte adhesion molecules on endothelial cells via nuclear factor κB. The aim of this study was to evaluate the effects of Ang2 and VEGFA on ocular autoimmune inflammation.

Methods

We measured the concentrations of Ang2 and VEGFA in vitreous samples among patients with uveitis. Vitreous samples were collected from 16 patients with idiopathic uveitis (uveitis group) and 16 patients with non-inflammatory eye disease (control group). Experimental autoimmune uveoretinitis (EAU) was induced in B10.BR mice with a human interphotoreceptor retinoid-binding protein-derived peptide. The retinochoroidal tissues of the EAU mice were removed, and the mRNA levels of Ang2 and VEGFA were examined. EAU mice treated with anti-Ang2, anti-VEGFA, a combination of anti-Ang2 and anti-VEGFA, anti-Ang2/VEGFA bispecific, or IgG control antibodies were clinically and histopathologically evaluated.

Results

The protein levels of Ang2 and VEGFA were significantly higher in the vitreous samples of patients with uveitis than in controls (P<0.05). The retinochoroidal mRNA levels of Ang2 and VEGFA were significantly upregulated in EAU mice compared to controls (n = 6, P<0.05). Although there was no significant difference, treatment with anti-VEGFA antibody reduced the clinical and histopathological scores. However, treatment with anti-Ang2 antibody reduced the clinical and histopathological scores (n = 18–20, P<0.05). Furthermore, these scores were further decreased when treated by inhibiting both Ang2 and VEGFA.

Conclusions

Based on these results, VEGFA and Ang2 were shown to be upregulated locally in the eye of both uveitis patients and models of uveitis. Dual inhibition of Ang2 and VEGFA is suggested to be a new therapeutic strategy for uveitis.
Blood pressure and heart rate variability responses following an acute bout of vinyasa yoga and a prolonged seated control: A randomized crossover trial
Authors: Thrower Alexis , Barone Gibbs Bethany , Alansare Abdullah , Sherman Sally , Davis Kelliann
Published: November 2023

Vinyasa yoga is moderate-intensity physical activity, yet physiological responses are poorly characterized. The purpose of this study was to examine the effect of a vinyasa yoga session on autonomic/cardiovascular functioning in healthy adults. A randomized crossover design took place at the Physical Activity and Weight Management laboratory (Pittsburgh, PA; n = 18), and included two experimental conditions: 60 minutes of vinyasa yoga or a seated control, and measurements were taken at baseline, 5-minutes, and 65-minute post-conditions. The primary cardiovascular-related outcomes of this study included blood pressure (BP), heart rate (HR), and HR variability (HRV) measures [natural log transformed (ln) standard deviation of normal-to-normal R-R intervals (SDNN), root mean square of successive differences (RMSSD), high frequency (HF), and low frequency to high frequency ratio (LF/HF ratio)]. Linear mixed effects models were used for data analyses. Systolic BP was 8.14 mmHg lower at 5 minutes post yoga (p<0.001) but was not different 65 minutes post, compared to the control. HR was higher at 5- and 65-minutes post yoga compared to the control (10.49/4.70 bpm, respectively, both p<0.01). HRV was lower (worse) at 5 and 65 minutes post for lnSDNN, lnRMSSD, and lnHF (all p<0.01). LF/HF ratio was higher (worse) at 5 minutes post yoga compared to the control (difference = +0.38, p = 0.025), but not different at 65 minutes post between conditions. Compared to prolonged sitting, vinyasa yoga had variable effects on post-session autonomic function including favorable BP responses and unfavorable HR and HRV responses, further investigation is warranted.
The potential of online object-based learning activities to support the teaching of intersectional environmentalism in art and design higher education
Authors: Willcocks Judy , Mahon Kieran
Published: November 2023

In 2019, the University of the Arts London (UAL) declared a Climate Emergency and undertook to make sustainability a required part of the student learning experience. Subsequently, in 2021, UAL published an anti-racism action plan and declared itself an activist university. These initiatives require educators across UAL’s six constituent colleges – of which Central Saint Martins (CSM) is one – to underpin creative arts learning and teaching with an understanding of global ecologies and societal structures. Since the advent of the COVID-19 pandemic, a considerable amount of this teaching has been delivered online. This case study – based on data gathered from students participating in online workshops – seeks to understand how established teaching practices, such as object-based and experiential learning, can be mobilized to support student understanding of these complex global and societal issues in an online learning environment. We also address the challenges and benefits of teaching art and design subjects using educational technology and ask whether experiential pedagogies can be successfully translated for delivery online.
Art, assessment and uncertainty
Authors: Fitch Sebastien
Published: November 2023

Of all academic fields of study, few encounter as much difficulty with issues of assessment than the fine arts. Yet despite calls for greater transparency and accountability at the post-secondary level, the majority of relevant research and literature focuses on primary and secondary school instruction; post-secondary instructors are essentially abandoned to wrestle with the apparently irreconcilable goals of quantifiable measures of assessment, on the one hand, and the chaotic nature of the creative process, on the other. Given the above, the goal of the present research is to add to the understanding of the pedagogy of post-secondary studio instruction by examining how instructors go about the problematic exercise of assessing their students. Findings indicated a strong sense of confusion amongst participants and a need for teaching institutions to invest more in instructor training and support in order to increase dialogue amongst faculty and the dissemination of best practices.
Linking empathy, feedback and iteration: Five skills to strengthen the student–teacher relationship in the design studio
Authors: Lopez-Leon Ricardo
Published: November 2023

This article focuses on feedback, a one-on-one design teaching practice that teachers approach intuitively and has been crucial within the design studio. However, although healthy student–teacher relationships are fundamental for feedback, research on understanding them deeply or developing them is still incipient. This research contributes with a tool for teachers to strengthen student–teacher relationships. The tool highlights that teachers must practise empathy as an iterative process. The approach was through a three-phase research methodology. First, a literature review on empathy and feedback aimed at understanding their relationship. In-depth interviews with students correspond to the second phase, exploring the role of student–teacher relationships in motivation and performance. Finally, in the third phase, a five-skill/stage cycle was put into practice during feedback within the design studio: the iterative empathy model. Results show that student–teacher relationships strengthen by practising five skills iteratively through a five-stage process: openness, perception, comprehension, communication and action. Consequently, students’ motivation and performance also improve.
Making: Place, material and metaphor
Authors: Niedderer Kristina , Townsend Katherine , Potter Gemma
Published: November 2023

The editorial highlights how the practitioners featured in issue 14.2 seek intrinsic value within and through making, supported by relationships with the natural and social world. The contributions are clustered into three themes. In ‘materiality and nature’, Tara Chittenden explores ‘Ceramics in the wild: Deep mapping and the moon jars of Adam Buick’, and how the ceramicist’s vessels represent the cycle of a material, and life itself. Myriam Perret‘s ‘Rhythms in the production and commercialization of crafts in Chaco’ reports upon her ethnographic study of the Qow people of Argentina and their craft of cattail harvesting and weaving, revealing seasonal and weather-related choices. Theme 2, ‘making and metaphor’ includes ‘Data becomes quilt’, by Jayne Jackson, who analyses a range of influences and social semiotic meanings encoded within her own and others quilt-making. The relationship of social meanings and craft activities are researched by Miriam Gibson and Rachel Spronken-Smith’s ‘Learning in online and physical craft groups: Motivations and meanings’, while Linnea Kilpi, whose work is featured on the cover, presents ‘Meaning-making through experimental knitting practices’, supported by the concept of ‘Knittedness’. Theme 3, ‘tradition, heritage and the future’, begins with Sara Sintonen and Mikko Snellman’s portrait of ‘Tarmo Thorström’ whose contemporary craft practice is rooted in the cultural tradition of bobbin lace making in Rauma on the west coast of Finland. Wendy Ward’s review of the exhibition, We Are Commoners, speculates on how historical notions of sharing – as represented by ‘the commons’ and exemplified by the Right to Roam and Right to Repair movements – could be re-imagined as the basis for sustainable craft practice. Sarah Teasley’s (2022) Designing Modern Japan, is reviewed by Marie O’Mahony and the Tradition/Innovation: Craft and Future Intangible Cultural Heritage conference held at West Dean College in March 2023, by Paul Harper.
Data becomes quilt: Encoding meaning through social semiotics
Authors: Jackson Jayne
Published: November 2023

There are accepted academic traditions about how data is visually represented, most often in the form of graphs, tables and maps. To visually represent the findings of a study about quilt makers in New Zealand and be congruent with the research topic, the researcher made a quilt to represent the findings. While much of the existing research about quilts focuses on the analysis of meaning, this article is about encoding meaning in a quilt. The article describes the processes of design and making which drew on a diverse range of quilt making traditions and forms of data representation exemplified by the theory of social semiotics. Quilt design decisions were informed by pattern, symbolism and fabric choice and drew on traditions where quilts have been made to convey information such as quilts as signs for escaping slaves on the underground railroad, storytelling tivaevae quilts from the Cook Islands, and the contemporary temperature quilts where daily high and low temperatures are recorded. Data is also communicated in traditional ways such as through graphs made from fabric. This article describes the process of conceptualizing the design and includes photographs of the finished work.
Tarmo Thorström: A forward-thinking lace artist
Authors: Sintonen Sara , Snellman Mikko
Published: November 2023

Finnish lace artist Tarmo Thorström redefines the conventional understanding of lace, conceiving it as an absence rather than a presence – a philosophical stance that permeates his innovative bobbin lace creations. His artistic repertoire interlaces disparate themes, transgressing the boundaries of traditional lace artistry. The city of Rauma, located on Finland’s western coast, serves as both muse and canvas, showcasing Thorström’s evocative works in its urban landscape and holding annual bobbin lace festivals to commemorate this living tradition. Thorström’s engagement extends beyond artistic production, encompassing pedagogical and research endeavours that traverse the fields of craft education and studying materials. This multifaceted involvement is underscored by his publications, notably a work on bobbin lace crafting, highlighting its significance within the continuum of cultural heritage. Moreover, Thorström’s artistic praxis embodies sustainability imperatives, evident in his repurposing of discarded materials, such as reclaimed bobbins and threads. This ethos aligns with broader discourses on sustainable crafting practices and material ecologies. Beyond craft, Thorström’s artistic output serves as a locus for profound philosophical contemplation on the nature of existence and humanity’s relationship with the cosmos. This portrait article situates Thorström’s original approach within the larger discourse on materiality and artistic practice, shedding light on the transformative potential of lace as a medium for philosophical and artistic expression.

En analysant un choix d’œuvres de la postmémoire européenne, nous commenterons ici les diverses figurations de ces réécritures fictionnelles à propos de l’histoire coloniale, afin de souligner leur dimension prospective, fondée sur un acte de rupture qui, à son tour, dévoile l’idée d’une traduction des héritages mémoriels.
Políticas da escrita e da memória na ficção de Luandino Vieira
Authors: Taborda Moreira Terezinha
Published: November 2023

O estudo analisa o conto “Memória narrativa ao sol de Kinaxixi”, do escritor angolano José Luandino vieira, publicado na coletânea No antigamente na vida (1987), investigando como o processo criativo do escritor mobiliza e entrecruza dois momentos distintos de construção estética: o primeiro relacionado à memória cultural greco-latina e o segundo à memória cultural angolana. Ao recriar, por meio da reescrita do mito, a memória do narrador personagem Dinho em suas aventuras épicas pelo musseque Kinaxixi, a escrita luandina reorganiza a nossa percepção sobre a memória cultural angolana, apresentando-a como experiência estética que insere, nos discursos sobre o belo, o espaço e a cultura de Angola.

Published: November 2023

Globally, researchers have been struggling with the ethical and practical questions of implementing community-based population-level research interventions during the Covid-19 pandemic. The safety of researchers and participants while implementing the interventions, and the need to avoid overburdening a health system already under pressure, are priorities, but it is also important to understand community perspectives on research. This article analyses community opinions about restarting a population-level community-based intervention for the prevention and control of type 2 diabetes in rural Bangladesh in a population of 120,000. We used qualitative phone interviews, discussions with key stakeholders and consultation with a trial steering committee. Community members were able and interested to attend intervention group meetings, but Covid-19 preventative measures were not being implemented routinely. People with diabetes did not perceive themselves to be at particular risk from Covid-19. Community members were meeting in groups and felt safe among friends and neighbours, but they did not feel safe among ‘outsiders’. As a result of our community engagement, we restarted the intervention but controlled the size of the groups and screened group members and group facilitators for Covid-19 symptoms. Community engagement enabled community members to contribute to decisions about how to restart the intervention.
Quantifying Impacts of Regional Multiple Factors on Spatiotemporal the Mechanisms for Spatio-temporal changes of Net Primary Vegetation Productivity and Net Ecosystem Productivity: An Example in the Jianghuai River Basin, China
Authors: Chen Huimin , Wang Benlin , Zheng Liangfeng , Shahtahmassebi ZhengAmirReza
Published: November 2023

Despite much valuable research on the mechanisms for spatio-temporal changesof net primary vegetation productivity (NPP) and net ecosystem productivity (NEP), there is a paucity of information on assessing impacts of regional multiple factors on spatiotemporal researchs of NPP and NEP
in the complex environment. This study attempts to bridge this information gap using the Jianghuai Basin in China as a case study. Using a field campaign, remotely sensed imagery, socioeconomic data, and meteorological parameters, we developed a framework based on the Carnegie‐Ames‐Stanford
Approach (CASA) model, correlation technique, trend analysis, and landscape metrics to measure spatiotemporal changes in NPP and NEP from 2001 to 2018. The derived changes were then linked to regional multiple factors including climate, landscape factors, human activity, and land use change.
The results of the research can provide a scientific basis for vegetation evaluation, ecosystem assessment, and other aspects of the region.
IMU and Bluetooth Data Fusion to Achieve Submeter Position Accuracy in Indoor Positioning
Authors: Acar Ugur
Published: November 2023

Indoor navigation applications have become widespread in recent years with the ability of mobile phones which determine the position. Due to the inefficiency of global positioning system (GPS) indoors, other positioning methods have been developed based on local networks using technologies
such as Bluetooth, wireless networks, ultra-wideband signals, ultrasonic signals, and radio frequency identification modules. Various technologies yield high or medium accuracy. Combining data from multiple sources via fusion enhances location precision. In this study, indoor positions were
estimated using trilateration with Bluetooth devices, and the accuracy was improved by applying filters to the data from inertial measurement unit (IMU) sensors on the phone. As a result of combining Bluetooth and IMU data with data fusion, submeter accuracy was achieved. The results obtained
were tested at Yildiz Technical University-Istanbul Türkiye. It was determined that 92% of the data was obtained with submeter accuracy.
Ebû Abdurrahman es-Sülemî’nin Tabakâtü’s-Sûfiyye’sindeki Sûfî Tabakaları: Bölge-Şehir Dağılımının Serencâmı ve İşaret Edilen Sûfî Havzaları
Authors: ERASLAN Soner
Published: November 2023

Ebû Abdurrahman es-Sülemî’nin (ö. 412/1021) beş tabaka şeklinde tertip ettiği Tabakâtü’s-sûfiyye’sinde yüz beş sûfî yer almaktadır. Yaşadıkları dönem ise hicrî 161-378 yılları arasına tekabül etmektedir. Bu makalede Tabakât’ta yer alan sûfîlerin bulunduğu tabakaların bölge ve şehir dağılımları tablolar oluşturularak ele alınmış ve her bir tabakaya ait verileri gösteren tablolardaki oranlar yüzdelik dilimlerle ortaya konmuştur. Bölgelere işaret eden tablolar oluşturulurken Sülemî’nin beyanı esas alınarak İran, Irak, Suriye, Hicaz, Mısır ve Horasan bölgeleri üst başlıklar olarak belirlenmiştir. İran’da bulunan Horasan eyaleti ile Afganistan ve doğusuna uzanan Horasan bölgesi birbirinden ayrıştırılmış ve olası bir tedahül nispeten giderilmeye çalışılmıştır. Söz konusu tablolardan elde edilen verilere göre Hicaz, Mağrib ve Mısır bölgelerindeki sûfî popülasyonu düşük seviyelerde seyrederken diğer bölgelerde daha yüksek düzeyde olduğu gözlemlenmiştir. Özellikle Irak, Horasan ve İran bölgelerinin sûfî popülasyonu açısından daha zengin yerler olduğu görülmüştür. Bu durum şehirler bazında değerlendirildiğinde ise Bağdat ve Nişabur’un diğer şehirlere nispetle daha fazla sûfîye ev sahipliği yaptığı anlaşılmaktadır. Fakat tabakaların seyrettiği süreç göz önüne alındığında ve söz konusu tablolar bir bütün halinde değerlendirildiğinde çeşitli sebeplerden dolayı son tabakalara doğru genelde İran bölgesinin, özelde Nişabur şehrinin ön plana çıktığı görülmektedir. Tablolara yansıyan verilerden elde edilen bir diğer çıkarım ise ilk tabakalarda çoğunlukla merkez konumdaki şehirlerde yer alan sûfîlerin, süreç içerisinde nispeten küçük köy ve kasabalara da sirayet etmeleridir. Böylece tasavvufun zamanla toplumun farklı kesimlerinde de kök saldığı ortaya çıkmaktadır. Makalede üzerinde durulmak istenen bir diğer husus ise Sülemî’nin çeşitli sûfîlerden aktardığı rivayetlerin işaret ettiği tasavvuf havzalarıdır. Günümüzde Basra, Bağdat, Mısır gibi sûfî ekol/mektep isimleri tasavvuf tarihi, tasavvufa giriş ve tasavvuf el kitapları şeklinde derlenen çalışmalarda yaygınlık kazanmıştır. Sözgelimi sûfî mekteplerinden biri olan Basra ekolü, bir yanıyla Hasan el-Basrî’nin (ö. 110/728) “korku ve hüzün” anlayışıyla ön plana çıkarken diğer yanıyla da Râbiatü’l-Adeviyye’nin (ö. 185/801) “İlâhî aşk” tavrıyla anılmaktadır. Bu durum bölgeler üzerinden tasavvuf ekollerinin ele alınmasında birtakım problemleri de beraberinde getirmektedir. Nitekim aynı bölgelerde bulunan farklı tasavvuf anlayışları bu tasnif ile birlikte göz ardı edilebilmektedir. Sülemî’nin aktardığı bölge, şahıs ve aynı şehirde yer alan farklı tasavvuf anlayışlarına delalet eden üç ayrı rivayet günümüzde şayi olan sûfî mektepleri/ekolleri olgusuna yeni bir kapı aralayabilir. Dolayısıyla makalede ortaya konan tablolardaki verilerden elde edilen çıkarımlar yeni sorular ve bulgular doğrultusunda günümüze kadar süregelen sûfî mektepleri/ekolleri olgusunun yeniden gözden geçirilmesi gündeme getirilmiştir.

Published: November 2023

The continuation of the solution of the problem of determining the deformed state of the workpiece with constrained extrusion of rectangular brackets under conditions of plane deformation in the general case of misaligned arrangement of the punch and matrix is presented. Formulas have been obtained that allow for any specific value of the punch’s working stroke to determine the current coordinates of material points and accumulated deformations in the plastic deformation region located under the punch near the extruded thick wall. Formulas are derived that allow taking into account the effect of hardening of a deformable material on stresses and force parameters of extrusion, as well as the geometric results of the achieved shape change.

Published: November 2023

The results of an analysis of the mathematical dependences of the parameters of subtle impact damage on samples made of polymer composite materials with an impact-sensitive luminescent smart coating applied to the surface on the magnitude of the impact energy, constructed according to visual-measurement control data, are presented. The control was carried out both with and without the use of an ultraviolet lamp. It was revealed that the parameters of the detected damage (the area of the dent on the surface of the samples) are not related by a simple linear relationship with the impact energy, which indicates complex processes of destruction of the structure of the samples, including the manifestation of an abrupt transition from an elastic response to an inelastic response of the indented structure when the critical energy value is exceeded blow.

The article describes methods and tools for inspection of thickness and hardness of coatings of elements of ball shut-off valves (ball plugs), which are one of the main elements of main pipelines and distribution networks. Properties of nickel-phosphorus (ENP) coatings most frequently used to protect ball plugs from corrosion and abrasion are analyzed. Various methods and means of control are considered. In the process of experimental studies, the thickness of coatings was measured by magnetic induction and eddy current methods of nondestructive control, as well as by ball abrasion method. Hardness values were measured by microvickers and ultrasonic contact impedance methods. The main sources of measurement errors were identified. Conclusions are drawn for each of the methods used in the incoming inspection of coatings.

EVALUATION OF THE QUALITY OF MACHINE PARTS' MICRORELIEF BY THE METHOD OF CORRELATION-SPECTRAL ANALYSIS OF THEIR IMAGES
Authors: Abramov A. D.
Published: November 2023

The article considers a method for estimating the parameters of the microrelief of the surface of machine parts by optoelectronic and computer means, as an integral part of the technological process of manufacturing machine parts with precision surfaces. The method is based on computer processing of images of the studied microreliefs, considered as a set of realizations of a stationary random process. The number of realizations of the random process is assumed to be equal to the number of lines in the analyzed microrelief image. The microrelief image is considered as a matrix of random numbers. For this matrix, mathematical expectations, variances, standard deviations, correlation moments and the normalized autocorrelation coefficient of honey are calculated for the columns of the matrix. To conduct research on the proposed method, an optical-electronic complex was used, consisting of an instrumental microscope with a video camera and a computer for digital processing of the obtained images of the microrelief f reference samples with different roughness. The surface roughness was estimated by standard methods on a profilograph and ranged from Ra = 0.025 µm to Ra = 0.130 µm. When developing software for correlation-spectral image processing, OpenCV tools and the C++ language were used. According to the research results, it was found that the nature of the correlation functions is largely determined by the parameters of the studied microreliefs. To identify the studied microreliefs, we determined the analytical dependences of the arithmetic mean deviation of the microrelief surface profile both on the average value of the variable component of the autocorrelation function and on the values of its spectral density. It has been established that for the identification of a microrelief by optical-electronic means, the most promising is the use of the spectral density of its autocorrelation function, calculated from its halftone image. The results of applying the correlation-spectral method for assessing the microrelief the working surface of an aircraft blade are presented.

Published: November 2023

A method of quantitative finite-element verification of stability of design and technological solutions of new generation portable radiographic equipment to the factors of transport accident at the stage of automated design of mathematical solid model of the shutter-type radiation head using software packages: "ZENIT-95" and "LS-DYNA" is proposed for consideration. The need for virtual quantitative assessment of stability of developed gamma detector components to emergency transport conditions at the design stage is largely due to the need to reduce costs for full-scale prototyping of technical solutions and test emergency tests. At the same time, production of prototypes equipped with radionuclide emitters without substantiating confirmation of the consistency of design solutions to extreme transportation conditions is certainly risky. Minimization of risk of making incorrect technical decisions at the stage of designing of radiographic control facilities of new generation with confirmation of consistency of design solutions to conditions of emergency transportation can be provided with the use of systems of automated design in 3D format and program-calculating modules "LS-DYNA" and "ZENIT-95" by finite-element calculations method. The object of the quantitative analysis of stability of the main functional unit of portable gamma detector to the transport accident factors by the finite element calculations method is a mathematical solid model of the radiation head conditionally containing radionuclide radiator and virtually exposed to transport accident factors: fall from height onto a target; thermal effects of fire. The 3D model of the WG as the main functional part of the gamma detector represents a logically connected system of elements, the state of which can be described by a set of differential equations, the solution of which using digital technology determines the stresses, strains and zones of thermal effect, allowing a quantitative assessment of mechanical strength and thermal stability of the structural solutions of the product. The results of finite element analysis in the software package "LS-DYNA" with a quantitative assessment of structural and strength stability of the radiation head of a gamma detector when falling from height, as well as the results of stability to thermal influence by the example of a finite element model of the radiation head in the software package "ZENIT-95" are presented.

The problem of identification and control of the current parameters of the transformer supplying the distribution electrical network (RES) under the conditions of the functioning of the automated control system and electricity metering (ASKUE) is considered. In this case, the parameters are the active and reactive components of the internal resistance of the transformer and the effective value of its emf. A system of algebraic equations for the desired parameters is obtained. The solution of the resulting system is carried out using a numerical algorithm. The developed method and its algorithm can be used to solve the problems of diagnosing the state of the network, optimizing the operating modes of the RES and monitoring power losses in it as part of the ASKUE.

The article describes the course of vibration measurements at a particular metallurgical plant, one of the workshops of which is equipped with vibration mills, from the formulation of the problem to the analysis of the results. The problem lies in the low quality of the floor on which four RVM-45 vibratory mills of the RVM-45/131.01 design are located, causing periodic loads and vibrations. The paper presents the results of vibration tests obtained through measurements at various points in the room during the startup, operation and shutdown of mills. The studies were carried out using a measuring device “Vibran-2.1”. The reason for the occurrence of progressive vibration caused by the intearactive operation of vibration mills RVM-45 is revealed. Ways to reduce the overall level of vibration in the room with the simultaneous operation of all mechanisms are proposed.
