Badiou’nun Yeni Komünizm Anlayışındaki Devlet Düşüncesi Üzerine Eleştirel Bir Değerlendirme
Authors: BİR Çağan
Published: December 2023

Badiou komünist idea ya da hipotezin farklı dönemlerde farklı sekanslar olarak gerçekleştiğini söylemektedir. Geliştirdiği Yeni Komünizm düşüncesi ikinci sekanstaki yanlışlara ve eksikliklere bir cevap niteliğindedir. Ona göre üçüncü sekans öncekilerden doğru dersleri çıkartmalı ve böylece yeni bir komünizm anlayışıyla hareket etmelidir. Bu sekans başlamamış olmasına rağmen Badiou birtakım ilkeler ve bu sekansın nasıl olacağına ve olması gerektiğine dair bazı öngörüler öne sürmektedir. Yeni komünizmde devlet 20. Yüzyıl sosyalist rejimlerindeki gibi olamaz çünkü Badiou’ya göre sosyalizmin kurulma mantığında bir sorun vardır. Makalenin konusu Badiou’nun eleştirileri ve 20. yüzyıl sosyalizmine alternatif olarak ileri sürdüğü anlayıştır. Proletarya diktatörlüğünün 20. yüzyıldaki uygulaması olan parti-devlet modelinin eleştirisi üzerinden kendi modelini önermektedir. Makale bu yeni modeldeki devletin olanaklı olup olmadığını tartışmaktadır. Badiou üçlü yapı dediği sistem içinde devletin zayıf olması gerektiğini savunmaktadır. Çalışmanın iddiası, zayıf devlet yerine klasik Marksist tasarımdaki önce devrimin bazı görevlerini yerine getiren güçlü bir devletin giderek sönümlenmesi fikrinin daha gerçekçi ve olanaklı olduğudur. Zayıf devlet daha işlevseldir ve yirminci yüzyıldaki hatalara düşmeyi engelleyecektir diye düşünmek bir yanılgıya götürmektedir. Çalışmanın amacı, Badiou’nun zayıf devlet düşüncesini eleştirel bir şekilde değerlendirmektir. Ekonomi politiği atlamak Badiou’nun sosyalizm ve komünizm arasındaki ayrımı görmesini engellemektedir. Bu da geçiş dönemini doğru değerlendirememesini getirmektedir. Üçlü yapı, parti-devlet modeli karşısında baskıcı olmadığı ve iktidarı tek elde toplamadığı için daha doğru bir model gibi görünmektedir fakat devletin zayıflığı meselesi ancak pratikte, politik konjonktür içinde çözüme kavuşabilir. Makalenin temel eleştirisi Badiou’nun önceki deneyimlere ve anlayışlara yönelttiği eleştirilerin etik bağlamda önemli olduğu fakat politik olarak yetersiz olduğudur.
Investigating (in)coherence in Tyneside English(es): sociophonetic variation spectrums of face, goat, price and mouth in the DECTE corpus
Authors: AMAND Maelle
Published: December 2023

The present study investigates the co-occurrence of face, goat, price and mouth vocalic variants in the Tyneside Linguistic Survey (TLS, Strang, 1968). The analysis is based on the original fine-grained transcriptions of the TLS sociolinguistic interviews across a sample of 44 predominantly working-class speakers (men/women, older, middle-aged and teenagers). Multiple Factorial Analysis and cluster analysis were combined to identify sub-groupings in the variety based on the entirety of the transcriptions (consonants, stressed and reduced vowels), and to investigate coherence across these vocalic variants. The results point towards major gender and class effects with four clusters of speakers characterised by varying degrees of accentedness. Overall, lower-status women and slightly higher-status women distinguish themselves through distinct variant choices. Differences amongst men of either status can best be measured through the extent to which they use the traditional variants.
Probing the Interfacial Structure of Aqueous Surfactants through Helium Atom Evaporation
Authors: Gao Xiao-Fei , Hood David , Bertram Timothy , Nathanson Gilbert
Published: December 2023

Dissolved helium atoms evaporate from liquids in super-Maxwellian speed distributions because their interactions are too weak to enforce full thermal equilibration at the surface as they are "squeezed" out of solution. The excess speeds of these He atoms reflect their last interactions with solvent and solute molecules at the surfaces of water and other liquids. We extend this observation here by monitoring He atoms evaporating from salty water solutions coated with surfactants. These surface-active molecules span neutral, anionic, and cationic amphiphiles: butanol, 3-methyl-1-butanol, pentanol, pentanoic acid, pentanoate, tetrabutylammonium, benzyltrimethylammonium, hexyltrimethylammonium, and dodecyltrimethylammonium. The helium energy distributions, recorded in vacuum using a salty water microjet, reveal a sharp distinction between neutral and ionic surfactant monolayers. Helium atoms evaporate through neutral surfactant monolayers in speed distributions that are similar to a pure hydrocarbon, reflecting the common alkyl chains of both. In contrast, He atoms appear to evaporate through ionic surfactant layers in distributions that are closer to pure salty water. We speculate that the ionic surfactants distribute themselves more loosely and deeply through the top layers of the aqueous solution than do neutral surfactants, with gaps between the surfactants that may be filled with salty water. This difference is supported by prior molecular dynamics simulations and ion scattering measurements of surfactant solutions.
PM2.5 exposure disparities persist despite strict vehicle emissions controls in California
Authors: Koolik Libby , Alvarado Álvaro , Budahn Amy , Plummer Laurel , Marshall Julian , Apte Joshua
Published: December 2023

As policymakers increasingly focus on environmental justice, a key question is whether emissions reductions aimed at addressing air quality or climate change can also ameliorate persistent air pollution exposure disparities. We examine evidence from California’s aggressive vehicle emissions control policy from 2000-2019. We find a 65% reduction in statewide average exposure to PM2.5 from on-road vehicles, yet for people of color and overburdened community residents, relative exposure disparities increased. Light-duty vehicle emissions are the main driver of the exposure and exposure disparity, although smaller contributions from heavy-duty vehicles especially impact some overburdened groups. Our findings suggest that a continued trend of emissions reductions will likely reduce concentrations but may not reduce relative disparities without greater attention to the systemic factors leading to this disparity.
Crucial Effect of Surface Oxygen Species on CO2 Electroreduction Performance in Ti@Cu Single Atom Alloys
Authors: Zhang Xue-long , Wu Zhi-jun , Zhang Wei , Sun Fu-li , Lin Cun-biao , Chen Wen-xian , Zhuang Gui-lin
Published: December 2023

Here, we theoretically screened and explored the catalytic mechanism of electrocatalytic CO2 reduction reaction (eCO2RR) on Ti@Cu single atom alloy (SAA) and its oxidized variants (O-Ti@Cu and OH-Ti@Cu), focuseing on the effect of surface oxygen species on catalytical activity and selectivity under varying acidity and applied potential. Thermodynamically, Ti@Cu can be easily synthesized and oxidized in an aqueous solvent, as indicated by its low formation energy (-1.60 eV) and free energy (-0.92 eV) for oxidation. Catalytically, the introduction of bystander oxygen species facilitates the hydrogenation of residual *O after the generation of C2 products in eCO2RR on the Ti@Cu surface. This results in an inclination for eCO2RR on Ti@Cu to predominantly produce C1 product CH4 (ΔGRDS = 0.51 eV), while on the O-Ti@Cu and OH-Ti@Cu surfaces, there is a respective tendency towards the production of C2 products CH2CH2 (ΔGRDS = 0.51 eV) and CH3COOH (ΔGRDS=0.45 eV). Importantly, the potential required for eCO2RR on pure Ti@Cu is 0.70 V, notably lower than the 0.86 V needed for the *O hydrogenation. This confirms the stability of oxygen species (*O and *OH) on Ti@Cu under electrochemical conditions. Furthermore, the catalytic mechanism under varying electrochemical conditions (different potential and acidity) revealed that Ti@Cu favored CH4 production at pH = 1, 7, and 13, whereas both O-Ti@Cu and OH-Ti@Cu surfaces tended to produce CH2CH2 and CH3COOH at pH 1 and CH4 at pH = 7 and 13. This study contributes to our understanding of the catalytic mechanism of eCO2RR under realistic electrochemical conditions.
The carbon footprint of artificial intelligence in materials science
Authors: Korolev Vadim , Mitrofanov Artem
Published: December 2023

While artificial intelligence drives remarkable progress in natural sciences, its broader societal implications are mostly disregarded. In this study, we evaluate environmental impacts of deep learning in materials science through extensive benchmarking. In particular, a set of diverse neural networks is trained for a given supervised learning task to assess greenhouse gas (GHG) emissions during training and inference phases. A chronological perspective showed diminishing returns, manifesting themselves as a 28% decrease in mean absolute error and nearly a 15000% increase in the carbon footprint of model training in 2016–2022. By means of up-to-date graphics processing units, it is possible to partially offset the immense growth of GHG emissions. Nonetheless, the practice of employing energy-efficient hardware is overlooked by the materials informatics community, as follows from a literature analysis in the field. On the basis of our findings, we encourage researchers to report GHG emissions together with standard performance metrics.

Los derechos sexuales y reproductivos en mujeres con discapacidad intelectual. Análisis con enfoque de género a partir de una revisión sistemática
Authors: Pérez-Curiel Patricia
Published: December 2023

El presente artículo aborda la salud sexual y reproductiva de mujeres con discapacidad intelectual desde una perspectiva de género y derechos humanos. Históricamente, estas personas han enfrentado estigmatización y suposiciones erróneas sobre su sexualidad y capacidad de tomar decisiones. Sin embargo, en la era de los ODS y la Agenda 2030, se enfatiza la necesidad de no dejar a nadie atrás, lo que debe incluir, por su puesto, a las personas con discapacidad. La evolución en la conceptualización de los derechos sexuales y reproductivos ha supuesto un creciente interés en su estudio, subrayando la importancia del empoderamiento y la autodeterminación. La Convención sobre los Derechos de las Personas con Discapacidad (CDPD) reconoce estos derechos. Por ello, se debe evitar que se siga mirando a las mujeres con discapacidad intelectual, como tradicionalmente se ha hecho, con representaciones contradictorias que las perciben y definen como asexuadas, niñas eternas o personas altamente vulnerables. El artículo se basa en una revisión exhaustiva de la literatura científica centrándose en tres temáticas: relaciones interpersonales, salud sexual y reproductiva, y embarazo. Un enfoque basado en derechos humanos, igualdad de género e inclusión garantizará que las mujeres con discapacidad intelectual tengan acceso a una salud sexual y reproductiva plena.
Confronting Sexist Comments: Verbal (Im)Politeness in Spanish and German
Authors: Topf Monge Guiomar
Published: December 2023

Este artículo examina, desde el punto de vista pragmático, las reacciones verbales ante un comentario microsexista. El objetivo consiste en definir y analizar el acto de habla «enfrentarse a comentarios sexistas» centrándose en las estrategias de imagen social utilizado entre estudiantes. El estudio se ha llevado a cabo en la Universidad Pablo de Olavide, Sevilla, entre estudiantes españoles y Erasmus alemanes con ayuda de un Discourse Completion Task. El objetivo consiste en verificar cómo las estrategias de (des)cortesía verbal, definidas por Culpeper, Bousfield y Wichmann (2003) y Bousfield (2008) varían dependiendo, primero, de la lengua y la cultura española o alemana y, segundo, del género de los hablantes. Los estudios interculturales (Siebold y Busch, 2015) predicen que los hablantes españoles suelen hacer más uso de estrategias centradas en la imagen positiva que los alemanes, y las investigaciones feministas (Mills, 2005) indican que se espera un comportamiento lingüístico más cortés de las mujeres que de los hombres. Los resultados muestran que la valoración negativa del comentario sexista era más prevalente cuando se trataba de la cultura española y de hablantes mujeres, mientras los hablantes alemanes y los varones de ambas culturas evitaban más frecuentemente el enfrentamiento. Los resultados también apuntan a que «enfrentarse a comentarios sexistas» puede considerarse un acto de habla en el que las diferencias interculturales entre estudiantes españoles y alemanes son menos relevantes que las diferencias entre hablantes de un y otro género.

Enhancing data accuracy with design of a web-based citizen data management application for neighborhood/residential unit
Authors: Jarti Nanda , Hutabri Ellbert , Putri Weni Lestari
Published: December 2023

Citizen data is critical in making appropriate decisions by neighborhoods/residential units (RT/RW) and sub-districts. Therefore, citizen data must have a high level of validity. In Tiban Lama Sub-district, Batam City, at the RT/RW level, citizen data management is still done manually, so problems often occur such as inaccurate data, delays in updating data, limited data access, difficulties in analysis, and difficulties in data coordination, decision-making errors in determining social assistance recipients, and obstacles in data management at Integrated Service Centers (Posyandu). To overcome this problem, a web-based citizen data management application is needed, where residents can upload the required data through the application by attaching supporting documents and the data will be verified by the RT/RW. This application can help villages and RT/RW manage citizen data and make the right decisions for their citizens. Based on the implementation of the activity, a positive response was obtained from the Head of Tiban Lama Village and the RT/RW level of Tiban Lama regarding the use of web-based applications.
Time-kill kinetics of Piper betle L. ethanolic leaf extract on methicillin-sensitive Staphylococcus aureus
Authors: Lao Ryan Christopher Co , Manglicmot Yabes Ailyn
Published: December 2023

Staphylococcus aureus is one of the main pathogens in community and hospital infections that could cause mild skin infections to severe life-threatening bacteremia. Piper betle has shown antibacterial activities against S. aureus but its pharmacodynamics remains unclear despite its widespread availability in many over-the-counter preparations. This study aimed to describe the time-kill kinetics of P. betle extract against methicillin-sensitive Staphylococcus aureus ATCC 29213 (MSSA). Time-kill kinetics were conducted to describe the killing rate of P. betle extract by its effects on MSSA lag time duration, growth rate, and maximum optical density. The surviving colonies at different time-points after exposure to P. betle extract at minimum bactericidal concentration were also determined. Subinhibitory concentrations elucidated its concentration-dependent antibacterial activity by maintaining a trend of increasing lag time, decreasing growth rate, and decreasing maximum optical density as the concentration increases. In particular, concentration at 1250 μg/mL or 0.5 x minimum inhibitory concentration (MIC) showed consistent significant findings across these parameters. Concentrations at MIC and above did not show growth, indicating MSSA growth inhibition or death. P. betle extract’s bactericidal effect started immediately within two (2) hours and was sustained until no growth was observed from the eighth hour and beyond. P. betle extract maintained antibacterial activities against MSSA at subinhibitory concentrations and has also exhibited immediate and sustained bactericidal effect at minimum bactericidal concentration (MBC).

Numerical age calibration of the Albian/Cenomanian boundary
Authors: Scott Robert W. , Oboh-Ikuenobe Franscisca E. , Benson Don G. , Holbrook John M.
Published: December 2023

New biostratigraphic and sequence stratigraphic correlations of the U.S. Western Interior Albian/Cenomanian sections with North Texas and European sections calibrate the Albian/Cenomanian boundary at 97.2 Ma, which supports previous correlations in the Western Interior. This age, however, is 2.4 myr younger than the recent calibration at 99.6 Ma derived from radiometric ages of volcanic beds with diagnostic marine fossils in northern Japan. This discrepancy suggests that additional analyses are required to test the age calibration of the geologic time scale. New data of cosmopolitan dinoflagellates enable direct correlation with the European reference sections of the Albian and Cenomanian. Previous correlations in the Western Interior were based on endemic or Boreal ammonites. The first and last occurrences of dinoflagellate species bracket the Albian/Cenomanian boundary in Europe and many of these species also bracket the Clay Spur Bentonite bed previously dated 97.17±0.69 Ma. The high number of radiometrically dated bentonites in the Western Interior provides a numeric age control for the ranges of many dinoflagellates. Sequence stratigraphic correlation of the North Texas section with the U.S. Western Interior sections also demonstrates that the Clay Spur Bentonite bed correlates with the Ablian/Cenomanian boundary in Texas defined by the ammonite succession. The flooding contact SB WA6 in Texas at the Albian/Cenomanian zonal boundary of Stoliczkaia dispar and Mantelliceras mantelli correlates into the Western Interior with an erosional sequence boundary SB4 at the base of the Romeroville Sandstone in New Mexico and the Dakota Sandstone in Colorado. This contact correlates with the base of the Belle Fourche Shale that overlies the Clay Spur and the Mowry Shale in Montana. The revised correlation of the Western Interior poses two questions. 1) What is the accurate age of the boundary? Both cannot be correct. 2) What were the durations of the Albian and Cenomanian stages? Cyclostratigraphic analyses estimate that the Albian was 11.9 to 11.6 myr in duration but the Western Interior data project the duration at about 15 myr.

Authors: FİLAZİ Ahmet , YİLMAZEL Rustem , PUL Muharrem
Published: December 2023

In this study, the electrical conductivity of cement mortars formed by additive waste iron chip was investigated. Mixtures with fixed water/cement (0.5) ratios and different ratios of iron chip were prepared. Cement mortars were prepared by adding 0%, 1%, 2%, 4%, 8% and 16% by weight of cement in the mixtures and waste iron chip in the range of 0.5 mm to 4 mm in size. Firstly, the flow test was applied to the cement mortars cured in normal water for 7 and 28 days and their flexure and compressive strengths were determined. Then, the electrical conductivity test was applied to the cement mortar samples. As a result, it was observed that the flow diameter values increased as the average length increased from 0.5 mm to 2 mm in 1% and 2% additive of waste iron chip. It was determined that 1% waste iron chip was higher at 4.54% compressive strength compared to the reference sample. As the amount of added waste iron chip increased, the electrical resistivity value in the samples decreased and the electrical conductivity value increased along with it. At the same time, it was determined that the added iron chip size also increased the electrical conductivity.
Views and Value of an Undergraduate General Education on Advancing Student Attitudes and Engagement with Science
Authors: Strzalkowski Nicholas , Sobhanzadeh Mandana
Published: December 2023

The enhancement of science literacy is a longstanding educational goal of liberal education programs. We conducted a mixed methods study to investigate undergraduate student science attitudes and engagement with science, with specific interests on student program (science vs. nonscience), level of study (junior: 1st and 2nd year, vs. senior: 4th+ year), and over a single general education science literacy course (pre vs. post). Data were collected through an online questionnaire (n=272) and semi-structured interviews (n=19). We found that self- assessed science literacy was higher post compared to pre, in senior compared to junior and for science compared to nonscience students. In contrast, interest in learning science topics did not increase pre-post or junior-senior but was high overall. Belief in pseudoscience was also high overall, including senior and science students, groups we expected pseudoscience belief to be lower. This work highlights the need to align science curriculum with student interests while differentiating science from pseudoscience topics.

Published: December 2023

Critical thinking skills are one of four skills that students must have in the 21st century. However, several research results show that students' critical thinking skills in Indonesia are still very low. This research aims to test the effectiveness of the Problem-Based Flipped Classroom (PBFC) model assisted by e-Modules in improving the critical thinking skills of prospective physics teachers. This type of research is quasi-experimental with a non-equivalent control group design. The research was conducted at the Physics Education Study Program at the University of Mataram. The research subjects consisted of 52 prospective physics teachers who were studying Basic Physics I. Data was collected using a critical thinking skills test given before and after treatment. The results of data analysis show that the average score of critical thinking skills of prospective physics teachers in the experimental class and control class both increased to the moderate category with N-Gain scores of 0.63 and 0.48 respectively. Based on the results of the t-test at the 95% confidence level with the degree of freedom dk= 52 it shows that there is a significant difference in the increase in Critical Thinking Skills between the experimental class and the control class with a value of tcount= 2.21 with a value of ttable = 2.01 . Apart from that, based on the results of the effect size calculation, it shows that the effectiveness of the E-Module assisted PBFC model in improving students' critical thinking skills relative to the conventional model is different in the large category. In other words, the PBFC model assisted by e-modules can be used as an alternative learning in the classroom to improve the critical thinking skills of prospective physics teachers or students in general.

Hoje em dia o papel da logística dentro do mercado de vendas está além do que somente realizar a entrega do produto no cliente final, e a Logística Reversa é um dos fatores que transforma uma simples entrega do produto em uma Gestão de Transportes, levando em questão não só a entrega, mas sim sua eficiência e aproveitamento. A grande proposta desse método de logística é oferecer um serviço de devolução de produtos rejeitados por algum problema (Ex. produto vencido ou avariado) com a retirada sendo feita de uma maneira eficiente e produtiva e o produto sendo encaminhado para a destruição ou reutilização de uma maneira ecológica.

No mundo atual, as grandes corporações encontram dificuldades na contratação de mão de obra qualificada quanto ao uso de línguas estrangeiras, pois a taxa de brasileiros que são fluentes na língua inglesa ainda é defasada. O objetivo deste trabalho é apresentar propostas e idéias de soluções para esta questão que ainda existe . Como método, foi feita uma revisão da literatura com trabalhos já publicados em revistas indexadas. Apesar de resultados divergentes e contraditórios, o Ensino a Distância (EAD) mostrou-se mais acessível, tanto no aspecto financeiro como no aspecto didático. Como conclusão, o EADparece ser uma boa opção de qualificação profissional, apesar de suas deficiências, no entanto , mais estudos são necessários para aprofundar essa nova modalidade de aprendizagem que parece ter chego para ficar.
Análise Comparativa dos Impactos da Pandemia de COVID 19 na Gestão Hospitalar: Uma Investigação entre Instituições Públicas e Privadas de Saúde
Authors: Mochnacz Isaura
Published: December 2023

A pandemia da COVID 19 demandou reorganização e adaptação dos serviços de saúde. Diante disso, objetivou-se realizar uma revisão bibliográfica visando entender a importância e o impacto da gestão hospitalar durante a pandemia de COVID-19, destacando as diferenças entre instituições públicas e privadas de saúde. Para tal propósito, conduziu-se uma busca no Google Acadêmico através das palavras chave: "COVID 19", "Gestão Hospitalar", "Instituições Privadas" e "Instituições Públicas". A gestão hospitalar desempenhou um papel crítico e desafiador durante a pandemia de COVID-19, enfrentando inúmeras dificuldades para fornecer cuidados adequados aos pacientes, principalmente pelas características dessa patologia, sua alta transmissibilidade e necessidade de atendimentos de alta complexidade. Tanto as instituições hospitalares públicas quanto as privadas tiveram que se adaptar rapidamente a um cenário de constante mudança, demandando a implementação de estratégias ágeis e inovadoras para lidar com o aumento exponencial de casos. Percebe-se que as instituições hospitalares públicas, já vinham sendo sobrecarregadas mesmo antes da pandemia devido a problemas estruturais e subfinanciamento crônico. Assim, os desafios foram potencializados: falta de recursos, tanto financeiros quanto de equipamentos de proteção individual, ausência de números suficientes de leitos, necessidade de aquisição de equipamentos essenciais e de treinamento profissional. Os hospitais privados, embora tenham enfrentado desafios, geralmente tiveram mais flexibilidade financeira para se adaptar às demandas emergenciais. A capacidade de investir em equipamentos, contratar profissionais adicionais e implementar protocolos de segurança rapidamente proporcionou uma certa vantagem em relação às instituições públicas.

Intraovarian injection of autologous Platelet Lysate (PL) can be considered a potential therapeutic strategy for ovarian function rejuvenation. Especially, in women diagnosed with Poor Ovarian Response (POR) or Primary Ovarian Insufficiency (POI), the exogenous administration of the autologous platelet-derived growth factors, influence positively the regulation of the serum Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), and Anti-Mullerian Hormone (AMH) and Estradiol (E2). Therefore, the evaluation of the serum levels of the aforementioned hormones was performed on 10 participants with a mean age of 43 ± 4 years diagnosed with POR or POI, who received intraovarian PL injection monotherapy. The monitoring of the serum hormone levels was performed for 3 months. The results of this study clearly showed that all participants were characterized by elevated levels of FSH and LH and reduced levels of E2 and AMH, prior to the PL injection. However, the levels of all hormones started to change after the 1st month of follow-up monitoring. Moreover, 40% of the participants conceived successfully either by natural way or after in vitro Fertilization (IVF). Considering these, the intraovarian injection of autologous PL exhibited promising evidence regarding the altering of hormone levels at physiological values. Moreover, the contained PL growth factors were implicated in angiogenesis promotion and also in toleration of the inflammatory microenvironment, regulating positively ovarian function. In conclusion, the intraovarian autologous PL injection is considered a safe, effective, and tolerable therapeutic strategy in women with POR or POI. Moreover, the results of this study were very encouraging, especially for the women with infertility issues, who want their genetic offspring.

This work describes a low computational cost image processing methodology for the identification of hand features for forensic applications – like height, gender, and ethnicity for suspect inference. The proposed methodology provides an adequately tailored sequence of image and geometrical processings on pictures of hands based on critical points like fingertips, finger valleys, and palm centers. As a result, we present the automatic measurements taken on 416 images compared with actual measurements from a manual caliper. The proposed approach leads to a 93.16% correlation (p - value < 0.05) related to the caliper, demonstrating the effectiveness of the technique.

Published: December 2023

Residual stress of laser-welded marine steel EH40 was experimentally and numerically analyzed considering weld defects (collapse, hump, and unfitness) and solid-state phase transformation (SSPT). A double-cylindrical source model was used to simulate the temperature distribution. The mean prediction errors of the model without and with weld defects along the plate thickness were 9.2 and 3.5%. Based on the thermodynamics of SSPT, microstructure fractions were computed and verified by weld hardness test results. Under the effect of SSPT, residual stress changed from compressive stress to tensile stress with the increase of the distance from the weld center. Weld defects have an influence on the value of residual stress, and this effect was greater when SSPT was considered. The affected zone extended from the vicinity of weld defects to the whole weld. The variations of longitudinal residual stress (LRS) and transverse residual stress (TRS) caused by weld defects and SSPT both exceeded 150 MPa. LRS was mainly affected by the loss and increase of metal, while TRS was affected by the stress concentration caused by shape geometry changes. Thus, the influence of weld defects on TRS was greater than that on LRS. The proposed finite element model considering weld defects and SSPT can be used to accurately predict residual stress in laser welding of marine steel EH40 and provide a theoretical basis to reduce welding stress.
Influence of Boron on Stress-Relief Cracking Susceptibility of T23 Steel

Published: December 2023

The effect of boron on stress-relief cracking (SRC) sensitivity in the coarse grain heat-affected zone (CGHAZ) of ASME SA213-T23 was studied by thermo-mechanical simulation. Then, the fracture mode, microstructure, carbide evolution, and boron segregation were observed by an optical microscope, a scanning electron microscope, a transmission electron microscope, and an electron probe microanalyzer. Finally, the mechanism of increasing boron content to improve SRC resistance was described. The results showed that when the boron content is lower than 0.0038 wt.-%, T23 steel is sensitive to SRC at 550–750°C (1022–1382°F), and the sensitive temperature range narrows as the boron content increases. When the boron content increases to 0.010 wt.-%, SRC can be eliminated. Moreover, boron addition did not improve grain boundary (GB) strength nor did it fundamentally change the fracture mode at high temperatures, but it significantly improved intergranular ductility. This is because the boron segregation at the GB inhibits the precipitation of M23C6 carbides, which reduces the void nucleation and alloy element depletion near the GB, thus significantly improving intergranular plasticity. The improvement of intergranular plasticity gives the grain sufficient time to deform and greatly improves the overall plasticity of the CGHAZ. As a result, the SRC resistance of the welded joint is significantly improved because the stress can be released through enough plastic deformation during postweld heat treatment or service.
