Authors: de Almeida Gonçalves Igor , Almeida Orlando Matheus de L. , Mouta Trautwein Leandro , de Almeida Luiz C. , Díaz Rafael Sanabria
Published: April 2024

Flat slab structures have been largely studied over the last decades since its structural behavior presents complex phenomenon, particularly the punching shear. The implement of openings near the columns is a common procedure and can affect the slab punching shear capacity. The high/ultrahigh-performance fiber-reinforced concrete (HPFRC/UHPFRC) has been demonstrated an alternative for structural reinforcement and connections. In this context the study of reinforcing the shear punching region with HPFRC has been carried out and showed positive results in terms of punching shear strength. This research carried out the simulation of a flat slab structure with openings reinforced with HPFRC in the punching region. The validation of the numerical model is done by comparing it with the results obtained from the experimental test and the behavior of the slab in relation to the shear caused by the punching. The numerical model will be developed by the commercial finite element software ATENA. Finally, a parametric study was conducted to evaluate the influence of the slab opening and the improvement in this behavior with the presence of HPFRC reinforcement in the column region.
Bridge Rehabilitation with Thermal Spray Zinc Coatings
Authors: Gagné Martin , van Leeuwen Martin , Duran Bernardo
Published: April 2024

Rapid overconsumption of natural resources is a primary driver of climate change. Reinforced concrete and steel, the two primary construction materials for bridges, have a heavy environmental footprint and can fail prematurely from corrosion. Extending the lives of existing bridge structures reduces mining and processing activity needed to produce new construction materials. Thermal spray zinc (TSZ) coatings have proven to be very durable for protecting and extending the lives of both reinforced concrete and steel bridges. Corroding reinforcing steel in concrete structures can be protected using TSZ external anodes. The anodes easily adhere to the contours of the bridge and colour match with the concrete. Steel bridges can be protected with TSZ coatings alone or as painted ‘Duplex’ TSZ coatings. TSZ coatings can be applied in the factory or in the field, making them ideal for the rehabilitation of existing bridge structures showing signs of corrosion.
An Experimental Study of Self-anchored Combined CFRP Cables
Authors: Ding Guozhen , Wu Chao , Feng Peng
Published: April 2024

Carbon Fiber Reinforced Polymer (CFRP) is an advanced material known for its lightweight, high strength, corrosion resistance, and fatigue durability, making it an ideal choice for cables in structural engineering. However, being an anisotropic material, CFRP faces challenges in anchoring due to its lower transverse mechanical properties compared to its tensile strength. In response to this issue, this paper designs and tests a self-anchored combined CFRP cable with variations in anchorage type, joint type, and CFRP plate thickness. The results reveal that interface shear stress causes delamination failure in the anchorage, leading to lower- than-expected load-bearing capacity. Through improved design and processing methods, interface damage in the anchorage is reduced, enhancing load-bearing capacity and achieving an ideal failure mode of cable body rupture.

Authors: Lanzinger Klaus , Krauser Larry
Published: April 2024

In order to build durable and sustainable prestressed concrete bridges and structures, preventing the steel components and the tendons from corrosion is key. Accordingly, for bridges with internal bonded post-tensioning, polymer duct systems should be used. The article gives an overview of the 50-years history of plastic ducts in post-tensioning, the selection of tendon protection levels (PL’s) according to fib bulletin 33 [1] and information for structural engineers regarding design and detailing of concrete structures with polymer ducts according to fib bulletin 75 [2].

Published: April 2024

This study aims to clarify the influence of the variability in the material properties of Glass Fiber- Reinforced Polymers (GFRP) and the modeling method of GFRP on the slipping behavior of high- strength bolted frictional GFRP joints. Therefore, study conducted a statistical evaluation of the variability in material properties and finite element (FE) analysis. As a result, the initial load-relative displacement relationship in the anisotropic model generally matched the experimental results. Furthermore, it was found that the Poisson's ratio did not have a significant impact on the slipping behavior in any direction. The material property that most influenced the slipping behavior was considered to be the shear modulus in the plate thickness direction.

Published: April 2024

The construction industry is behind other industries in productivity. With more large infrastructure projects to be built, it is essential that design and construction could be performed with high productivity. This paper focuses on how standardisation of bridges can result in higher productivity. A quantitative study was performed to examine essential parameters that have potential to increase productivity in the Swedish bridge construction industry; it also examines how standardisation could increase productivity; and how specific incentives of the three significant actors (contractor, client and design engineer) could be obstacles to productivity. The main findings are that the actors believe in standardisation as a way to increase productivity. Reinforcement layout was one important parameter to increase productivity. Contractor’s view on profit could be an obstacle to productivity. Increased productivity would be more sustainable infrastructure delivery and here the client has an important role to play.

Stainless steel as a structural material in the drive toward net-zero bridges
Authors: Backhouse Andrew , Baddoo Nancy
Published: April 2024

In the last few decades, duplex stainless steels have emerged as a candidate material for bridges situated in demanding environments. This paper outlines some of the new design rules in the Second Generation Eurocode for stainless steel, EN 1993-1-4, which are relevant to bridge structures. A main factor in choosing to use stainless steel in bridge building is longevity and very low lifetime maintenance requirements. The outcomes of a recent life cycle cost (LCC) comparison between a carbon steel and duplex stainless steel road bridge are presented. In recent years the carbon footprint of bridges has started to become more important. This paper outlines the current state of the art with respect to the carbon footprint of stainless steel production and offers an insight into how the use of stainless steel can reduce the carbon footprint of a bridge.
The impact on structural embodied carbon of using loads obtained from wind tunnel testing vs code-based loads
Authors: Nguyen Tung , Faseli Fabio , Manica Pietro , Kilpatrick John
Published: April 2024

RWDI possesses one of the world's most extensive portfolios of data from structural wind tunnel tests. Drawing upon our wealth of experience, RWDI has carried out studies to compare wind loads achieved by undertaking site-specific wind tunnel tests against values obtained using an analytical code-based approach. In one of the studies, the peak overturning moments of ten prominent tall buildings in the UK were estimated from wind tunnel tests conducted by RWDI. Comparing these loads against values based on Eurocode and the UK National Annex, wind tunnel testing led to an average 35% reduction in wind loads for structural design. The loading reduction is attributed to various important factors that are elaborated further in this paper. In addition, notable UK and worldwide case studies are presented to demonstrate the benefits of wind tunnel testing in delivering more optimised structures and contributing to the reduction of embodied carbon.

Why Sentiment Analysis-Based Metrics are Essential for Measuring Channel Performance on YouTube: An Experimental Study
Authors: Elbaş Hakan , Mesri Alparslan
Published: April 2024

YouTube is a universal social medium that lets its users share videos and write comments on shared videos. Comments of the users on Youtube videos can be useful for YouTube channel owners, and it is worth analyzing them in terms of sentiment. The rate of like/dislike on a YouTube video is not sufficient for estimating the attitude of users towards it. This study proposes a three-step method for this attitude: In the first step, a sentiment analysis task is applied to the user comments on the videos of the YouTube channel "iJustin". In the second step, a new metric named Sentiment Index (SI) has been proposed and the Sentiment Indexes of the videos have been calculated. In the third step, an analysis is performed to show if the SI metric is time-independent. As a result, it was seen that most of the comments left on the videos (89%) have been written within the first 30 days after the video was published. Our experiments revealed that comments left more than 30 days after publishing the videos change the average SI values of the videos by only 0.4%, and in this respect, the SI metric is negligibly affected by the time parameter.

Published: April 2024

Mevcut çalışmada endüstriyel uygulamalarda sıklıkla kullanılan AISI 4140 çeliğinin yüzey özelliklerinin geliştirilmesi ile aşınma dayanımının nasıl değiştiğinin belirlenmesi amaçlanmıştır. Bu kapsamda AISI 4140 çeliği farklı iki şiddette bilyalı dövme işlemine ve plazma nitrasyon işlemlerine tabi tutulmuştur. Mikroyapıda meydana gelen değişimler SEM ve XRD aracılığıyla belirlenirken yüzey dayanımında meydana gelen değişim mikrosertlik ölçümü ile belirlenmiştir. Plazma nitrürleme sonucunda yüzeyde oluşan ilave katmanın demir nitrür fazları olduğu görülmüş bununla beraber bilyalı dövme işlemlerinden sonra herhangi bir faz değişimi meydana gelmemiştir. Tüm işlemlerle birlikte numunelerin yüzey sertliklerinde artış sağlanmış ve plazma nitrürleme ile yüzeyde 700 HV0.2’ye varan sertlik artışı görülmüştür. Buna bağlı olarak en iyi aşınma dayanımı plazma nitrürleme işlemi ile sağlanmıştır. Aşırı bilyalı dövme de aşınma kayıplarının kayda değer miktarda azaltırken geleneksel bilyalı dövme işlemi aşınma dayanımı üzerinde sınırlı bir etki göstermiştir. Uygulanan yüzey modifikasyon işlemlerinin sağladığı sertlik artışı aşınma dayanımında görülen artışa neden olarak gösterilmiştir. Bilyalı dövmede beklenen etkinin görülmemesi ise yüzeyde oluşan pürüzlülüğe atfedilmiştir.

“Just a pocket knife, not a machete”: Large language models in TEFL teacher education & digital text sovereignty
Authors: Buendgens-Kosten Jules
Published: April 2024

This paper approaches AI in TEFL teacher education from a perspective of digital text sovereignty (digitale Textsouveränität). Digital sovereignty (digitale Souveränität) is a concept that goes beyond media literacy and data literacy as a set of skills, to include personal competences in a more Humboldtian vision of education. Digital text sovereignty focusses on all those aspects of digital sovereignty that apply to the reception and production of texts, from the ability to produce and consume digital texts to the development of a critically-reflexive attitude to these texts (Frederking, 2022; Frederking & Krommer, 2022), making it especially useful in contexts of TEFL teacher education.
This paper is based on an empirical study conducted within the EFL teacher education department of a German metropolitan university during the 2023 summer term. It analyses 21 student essays written after an interactive 90-minute training session on ChatGPT conducted in three intact TEFL teacher education seminars.
Qualitative content analysis is used to identify domains of digital text sovereignty discussed in these essays, and to identify key themes related to four aspects of digital text sovereignty: Mediality, Source Code, Intentionality, and Veracity. The findings might be of interest for researchers and teachers educators interested in (a) modelling digital text sovereignty as it applies to AI, and (b) developing teacher education material and programs that target digital text sovereignty in an AI context, or that aim to support (future) teachers in developing an AI-informed pedagogy.

Published: April 2024

Introduction: Spaced fiber bundles, less evident cell striations, deposition of collagen fiber bundles, and increased presence of fibroblasts in the cardiac tissue of rats that voluntarily and chronically ingested ethanol were observed by our research group. In addition, we observed increased proliferation and cell death of cardiomyocytes. To find out whether these changes lead to impaired heart functionality, some clinical tests were performed. Aim: to investigate whether chronic ethanol decreases the left ventricular performance assessed by exercise testing, electrocardiogram, and echocardiogram of male and female UChB strain rats. Material and methods: ten adult males and ten adult females, Wistar strain rats, named UChB (University of Chile), spontaneous high ethanol drinkers (consumption greater than 2 g ethanol / Kg body weight/day), and ten male UChB rats and ten adults female UChB rats, not exposed to ethanol, UChBC rats (controls) were used. Cardiac performance was evaluated by the stress test, electrocardiogram, and echocardiogram. Results: Exposed females showed ventricular morphological changes in the heart. The exposed females and males had the highest heart relative weight with females being larger than males. The exposed females showed altered electrocardiogram and echocardiogram. Conclusion: Chronic ethanol decreases the left ventricular cardiac performance in rats. Females are more sensitive to changes in cardiac electrical conduction.

Horrifying Whiteness and Jordan Peele's Get Out
Authors: Mollenthiel Julia
Published: April 2024

Abstract: Horrifying whiteness is a lens by which to read the paradox of white supremacists rendering Blackness as monstrous even as they terrorize Black people by executing physical and institutional attacks against them. As its name suggests, horrifying whiteness evokes the complex relationship between white supremacy and the horror genre calling attention to the violent white supremacist performances that are enacted on and off the big screen. In this article, I introduce my concept of horrifying whiteness which draws from previous Black scholarship on the gaze such as Frantz Fanon's Black Skin, White Masks (1952) and bell hooks's Black Looks: Race and Representation (1992) but distinguishes itself by rendering white supremacy and the gaze as horrific via the horror genre. As a case in point, Jordan Peele's Get Out (2017) epitomizes horrifying whiteness through its depiction of the Armitages and their clients who mask themselves as good innocent white people while they privately abduct and sell/purchase Black bodies and exploit them. By reading Peele's Get Out through the lens of horrifying whiteness, I consider how horror frameworks not only challenge white denial and white innocence, but provide a lens through which Black vulnerability can perhaps be most clearly seen.
Black Identity and Resistance Revisited through Jordan Peele's Get Out and Us
Authors: Baker Jayson
Published: April 2024

Abstract: This article focuses on Black male and Black female ways of seeing and being seen in Jordan Peele's Get Out and Us . Drawing on the theoretical ideas of cinema and Black representation introduced by Manthia Diawara and bell hooks nearly three decades ago, Get Out and Us stage Black male and female orientations challenging established scholarship on Black representation in contemporary movies. Diawara and hooks discuss how Black identity is formed by White Hollywood and Black American Auteurs. Their analysis focuses on who gets to look and who gets looked at from Black male (Chris in Get Out ) and Black female (Adelaide/Red in Us ) perspectives. The article concludes that Jordan Peele contributes to established discussion on Black identity in American film while providing important new critical insights into contemporary Black experiences and legacies of white supremacy in American culture.

Radical Natural Law
Authors: Donovan Josephine
Published: April 2024

Abstract: Natural law theory has a long history, going back to the Stoics. Ernst Bloch, a twentieth-century Marxist theorist, offered a compelling radical reconstruction of natural law, locating its source in the resistance of those whose natural law entitlements are being denied. That resistance, Bloch held, constitutes a critical standpoint, which forms the basis for radical natural law. Bloch restricted the concept to humans, but it is here proposed that animals too have critical standpoints which constitute the basis for radical natural law.
Designing Species
Authors: Cline Brendan
Published: April 2024

Abstract: Should we use modern bioengineering techniques to design species? An instrumentalist account of species’ value offers permissive guidance. But what if species exemplify final value? Is it always very good to create new species? Is it always very wrong to blend or modify existing species? In this paper, I argue that both extremes are implausible. However, final value theories struggle to deliver a flexible, moderate treatment of these issues, and so the ethics of designing species presents a challenge for final value theorists. Fortunately, a design-based account of the value of species has the resources to offer plausible, nuanced, context-sensitive guidance on the ethics of designing species. It holds that designing species is sometimes very bad, sometimes quite good, and sometimes neither very good nor very bad. The plausibility of these results lends credibility to the design-based framework, and gives final value theorists reason to prefer the design-based approach.
"Not a Girl, Not Yet a Woman": Suat Derviş, Nezihe Muhiddin, and Age in Turkey, 1923–35
Authors: Peruccio Kara A.
Published: April 2024

ABSTRACT: In the 1920s and early 1930s, Turkish women did not experience Kemalist politics in a monolithic fashion. Novels by Suat Derviş (1904/5–72) and Nezihe Muhiddin (1889–1958) served as critical commentary on women's experiences across different age cohorts. While the regime called for "new," "modern" women, those of a marriageable age found themselves in a paradoxical position: embrace the regime's reforms yet face familial and societal censure for this behavior. Derviş and Muhiddin were politically engaged, astute thinkers whose fiction documented transformations and continuities in the early republican era. In Behire'nin Talipleri (1923) and Fatma'nın Günahı (1924) by Derviş and Güzellik Kraliçesi (1935) by Muhiddin, the authors critically demonstrated that age produced distinct emotional and social outcomes for young Turkish women. I argue that both Muhiddin and Derviş highlighted and critiqued these persistent challenges and how often-contradictory demands for their subjecthood intensified in the early republican era.
Gestures of Connection: Victorian Technologies of Photography and Visible Mothering
Authors: Tange Andrea Kaston
Published: April 2024

Abstract: Victorian "hidden mother" photographs are portraits of babies in which adult figures are draped with textiles, blocked with furniture, tucked behind a mat, orotherwise (often ineffectively) obscured. Fascination with them habitually turns on their presumed erasure of nineteenth-century women's labor; however, modern assumptions about the production of these photos have shaped consumption of them. This essay locates these images within multiple contexts: the technologies of their production, growingsentimental ideals of middle-class motherhood, and the ways that carework and its cultural (in)visibilities varied widely by gender, race, and class in the period. Arguing thatthe mother figures' persistent presence (not hiddenness) is fundamental to these photographs, this essay makes a case for reading them as revealing intimacies and documenting tenderness rather than evincing erasures.

Design modification of elliptical vessel solar receiver system by response surface methodology has been carried out. The materials used in this study were locally sourced from Kenyeta Market Enugu, Onitsha Bridge Head Market, and Idumota Market Lagos. These materials were sourced based on categories of components element: support mechanisms made of mild steel plates, bolts, nuts, clamps, and water as heat transfer fluid. The reflector is made of aluminum foil tape while the vessel has a glass cover fitted with bolts and nuts, the receiver is made of copper pipe, aluminum pipe, galvanized iron pipes, and stainless steel pipes. The pipes were fitted into the vessel with chlorinated polyvinyl chloride 3⁄4 joint pipes, and journal-bearing mechanisms. Other features include the tracking system made of light dependent resistance sensors, a direct current motor, a pulley, a belt, an Arduino controller, and a thermal energy storage tank. The lagging material was an expanded Polyethylene sheet. Experimental data were measured with thermocouples, a digital panel, a Uni-T digital anemometer (UT363), and a digital solar power meter (SM206-SOLAR). Matrix Experimental design was used to develop an experimental model for the system. The developed system was tested to investigate the effect of various heat collectors with and without coating on its performance. It was established from the response optimization that the intercept factor was improved by 32.2%. Similarly, the theoretical efficiency was improved by 8.19% while the experimental thermal efficiency was improved by 6.99%.

PURPOSE. Study of the features of hydrobiological characteristics of zoobenthos development under conditions of an operating fish protection structure of a water-air curtain (WAC ) type at an energy facility.

   METHODS. Hydrobiological material on the qualitative and quantitative composition of zoobenthos in the water intake area of the Zainskaya State District Power Plant was collected, processed and analyzed. Particular attention is paid to the level of development of the biofouling agent - Dreissena, and the acclimating species, the Khanka shrimp. A comparative analysis of our own research and literature data on hydrobiological indicators of water quality according to the level of development of zoobenthos in the area of a fish protection structure such as a water-air curtain was carried out. The material was processed using generally accepted hydrobiological methods in the laboratory of the Department of Aquatic Bioresources and Aquaculture of Kazan State Power Engineering University.

   RESULTS. It is shown that a fish protection device like a water-air curtain (WAC) is a technical solution that, in the process of operation, changes the physical and chemical characteristics of the state of the ecosystem, especially in the bottom layer and soil, thereby shaping the characteristics of zoobenthos. It was revealed that a fish protection structure (FPS) like a water-air curtain does not reduce the species diversity of zoobenthos It has been shown that the WAC zone does not prevent the reproduction of Dreissena, but leads to a decrease in their numbers from 2 to 5 times compared to FPS with mesh cassettes, which increases the environmental significance of the WAC from the standpoint of combating biofouling on hydraulic structures.

   CONCLUSION. Observations of the state of the ecosystem in the area of operation of the water-air curtain and assessment of water quality based on zoobenthos indicators revealed high water quality in the area where the water-air curtain operates and an improvement in the ecological situation.

RELEVANCE. The insufficiently wide scope of gas turbine plants (GTP) is associated with the lack of widespread availability of gas pipelines supplying the main fuel – natural gas. Interest in alternative fuels and the search for the most suitable ones in order to switch from traditional energy sources has increased intensively over time. Currently, there are methods of gasification of solid fuels that expand not only the possibilities of using the fuel itself, but also pushing the boundaries of the applicability of GTP both in terms of production specialization and geographical location. Coal is the most affordable energy resource in the world, due to its prevalence, but its limited use in modern energy facilities is due to the worldwide policy of decarbonization of energy. Coal gasification makes it possible to increase energy characteristics and reduce emissions of harmful substances into the atmosphere when using coal.

   PURPOSE. Determination of the efficiency and expediency of using generator gas obtained from coal in gas turbine plant, as well as consideration of the possibility of its modernization.

   METHODS. To achieve set goal, an automated system of gas dynamic calculations of energy turbomachines (AS GDCET) will be used, which will calculate a mathematical model of a gas turbine installation and conduct numerical studies when characteristics change, as well as using a module for approximating the component composition of fuel. The research is carried out when the electric load of a gas turbine plant of the NK-16-18 ST type changes in the range from 15 to 18 MW.

   RESULTS. According to the results of the study, the dependences of the total hourly and specific fuel consumption, effective efficiency, temperature in the combustion chamber and at the outlet of the power turbine on changes in the electric load of the gas turbine installation were obtained. Having a lower calorific value, the expected synthesis gas reduces the electricalefficiency of the gas turbine engine, which is expressed in a decrease in efficiency by 3-4.5 %. At the same time, fuel consumption increases by about 4-5 times, which depends on the component composition of the fuel. At the same time, the temperature values at the exhaust of the gas turbine change by 26-37 °C.

   CONCLUSION. The use of synthesis gas as fuel for a gas turbine plant can provide sufficient efficiency in generating electric energy, but its use is rational only in situations of absence or unavailability of traditional gaseous fuels. The development of gasification technologies will increase the efficiency of use and reduce the cost of synthesis gas production. This will allow the introduction of gasification technologies at existing facilities and expand the scope of synthesis gas applications, which will ensure increased interest in this area among potential investors.

THE PURPOSE. Increased water consumption at power plants leads to a deterioration of the environmental situation not only in countries with limited water supply sources, but also in countries with significant reserves of fresh water. There is a need to consider the possibility of using an air condenser as an alternative use in industrial water supply systems at a power plant. To present a methodology for calculating the main characteristics of a condenser (condensation and reflux sections), to estimate the aerodynamic resistance and fan power for an air-cooled condenser as part of a steam turbine power unit. Determine the influence of air temperature and pressure in the condenser on the calculation of the air condenser. To develop recommendations for the selection of parameters of air condensers operating as part of steam turbine power units.

   METHODS. Methods for designing heat exchangers, modeling and intensifying heat exchange processes were used in the course of calculating an air condenser unit.

   RESULTS. A method for calculating an air-cooled condenser for a 110 MW condensing turbine has been developed. The analysis of the calculation of the heat transfer coefficient is given. The analysis of the values of the heat exchange area of the condensing unit is presented. The effect of pressure in the condenser on the main calculated characteristics of the condenser is shown. Recommendations for the selection of the fan capacity in the condenser and the design temperature of the cooling air have been developed.

   CONCLUSION. The issue of using air coolers in the power industry is still poorly covered in the literature, however, environmental problems and the shortage of fresh water are becoming more and more urgent all over the world. The development of air-cooling systems is a very topical issue for modern power engineering. It is shown that for stationary installations of condensation of water vapor, the most suitable is the hipped-roof arrangement of the heat-exchange sections with the lower arrangement of the fans. Quantitative estimates of the change in the heat transfer coefficient and the area of the heat-exchange surface are given for the pressure range of 8…20 kPa. The power consumption of the fan depends significantly on the temperature of the cooling air and the vacuum in the condenser.
