Authors: Carignani Elisa , Paci Augusta Maria , Borsacchi Silvia , Peruzzini Maurizio 
Published: August 2024

Abstract
Global Conversation on Sustainability (GCS) 2023 was enthusiastically welcomed by researchers of the National Research Council of Italy (CNR). Highly committed to international organizations such as IUPAC and ISC, the promoters participated to the 2023 edition of the Global Conversation on Sustainability hosting a local in person event held in one of the major CNR institute for chemistry research. The format was a round-table discussion involving colleagues of different age, gender, experience, and area of expertise, who participated to an informal dialogue with the aim of reflecting and sharing aspects of the respective research activities contributing to sustainable development goals. From many chemistry research areas, it emerged a wide range of subjects, which stimulated an interesting and purpose-oriented discussion. Therefore, GCS 2023 at CNR prompted a reflection on how improving chemists’ impact on sustainability including laboratories’ practises and on considering communication becoming part of scientific process. Transformation requires continuous investment in research and innovation and evolving scientific activities, but also requires synergies, collaborations and policy making on cross-cutting issues that can make this successful. Global initiatives as GCS, in the framework of international scientific organizations, represent a key global vehicle for enhancing the big area of science communication. Overcoming time and spatial limitations, these initiatives enable to link global and locally tailored in person events.

Published: August 2024

Abstract
This project involved the metallographic examination of Early and Middle Bronze Age axes with respect to their manufacture and processing. The processing from casting to finished axe determines the microstructure and thus the properties required for use – in this case the combination of hardness and ductility – of the object. However, the objects under investigation are valuable cultural assets that must not be destroyed. For this reason, a preparation method was developed that allows the microstructures to be analyzed in a minimally invasive manner so that the objects can be restored. The investigations have shown that all objects have undergone a multi-stage thermomechanical treatment after casting, but to different degrees, resulting in different usability properties.

Published: August 2024

Abstract
Reinforced concrete is a widely used building material in construction. However, under specific corrosive conditions, reinforced concrete structures are prone to corrosion, leading to a gradual decrease in durability and eventual destruction. This review first discusses the causes and mechanisms of degradation of reinforced concrete, and then various factors causing concrete degradation are analyzed in terms of environmental, material, and design factors. Subsequently, it explores various detection methods and technical means to accurately monitor and assess concrete degradation. Furthermore, it discusses protective measures, such as coatings, corrosion inhibitors, and surface treatments, that have been developed. This study provides an overview of the field’s findings by referencing previous research. Finally, the review provides an outlook on the future development of corrosion detection and control technology for reinforced concrete. With the rapid development of material science, computer technology, and other fields, new corrosion control technology will continue to make breakthroughs and progress.

Abstract
Greywacke, i.e., a non- to anchi-metamorphosed immature sandstone that contains more than 15 % clay minerals, occurs in most orogenic belts, with depositional ages ranging from Precambrian to recent. Our study focuses on thermomechanical rock properties of greywacke sampled in Kobeřice quarry (Lower Carboniferous Culm Basin, Drahany Upland, Bohemian Massif). Both relatively fine-grained and coarse-grained (with higher abundance of lithic fragments and small pebbles) intact rock core samples were tested. The experiment was divided into two sets. The first set made of the coarse-grained greywacke gave insight into the changes of properties across the whole temperature range, up to 1,200°C. The second set of samples was used to study the behavior of the fine-grained greywacke in the lower temperature range, up to 400°C. The lower temperature analysis showed an unexpected phenomenon at 200°C to 300°C, manifested by decrease in the strength coupled with higher values of deformation characteristics. These trends reverted at 400°C. The described phenomenon may have been caused by changes in water content combined with clay minerals composition alternation. Alternatively, it could be also related to the rock “paleotemperature memory.” On the wider temperature range, the greywacke holds relatively well to the lower temperatures, with the strengths decreasing slowly after 400°C and more rapidly after 800°C. At 1,200°C, partial melting at grain boundaries accompanied by formation of larger pores in the sample center was observed. Results of thermomechanical studies can be crucial during the design of underground constructions or for assessment of the fire damage on a rock-based constructions.
Bond Behavior of Seawater Sea-Sand ECC and GFRP Bars under Different Strain Rates and Bond Lengths: Experimental Study and Bond-Slip Modeling
Authors: Gao Shuling , Zhang Shilin , Zhu Yanping 
Published: August 2024

Abstract
The shortage of fresh water and river sand in marine areas has become a major problem hindering the production of concrete and limiting infrastructure development there. To this end, engineered cementitious composites (ECCs) were prepared by using untreated sea sand and artificially configured seawater. The tensile and compressive properties of ECC and the bonding properties between glass fiber–reinforced polymer (GFRP) bars and ECC were studied. The effects of ECC matrix type, bond length, and strain rate on the bonding performance were considered in the center pullout test, and a bond-slip prediction model was developed. The results indicated that replacing fresh water and desalinated sea sand with seawater and sea sand led to a significant improvement in the mechanical properties of ECC. Additionally, the bond strength and slip between ECC and GFRP bars were also improved. The bond strength of seawater and sea-sand ECC with GFRP bars decreased with increasing bond length (l) but increased with increasing strain rate (ε). Conversely, slip increased with bond length (l) but decreased with strain rate (ε). The dynamic bond strength and dynamic slip calculation models for bond length and strain rate are established, and the prediction model of the bond stress-slip relationship between GFRP bars and ECC for bond length and strain rate is proposed to provide a theoretical basis for the application of GFRP bars and ECC in structures.

Grade 10 Namibian Learners' Strategies for Solving Algebraic Word Problems
Authors: Iilonga Hesekiel Kaukolwa , Ogbonnaya Ugorji I. 
Published: August 2024

Solving mathematical word problems is a big challenge for many learners. One reason for the challenge could be the use of inappropriate strategies in solving mathematical word problems. In Namibia, many examiners’ reports show that learners do not attempt algebraic word problems fairly in examinations. This study investigated Grade 10 learners’ strategies for solving algebraic word problems in the Ohangwena Region, Namibia. The study followed a qualitative approach. A sample of 351 Grade 10 learners from ten secondary schools participated in the study. Krulik and Rudnick’s problem-solving strategies model was adopted as the framework that guided the study. Data was collected using the Algebraic Word Problem Solving Achievement Test and analysed using content analysis. The result shows that most of the learners could not use appropriate strategies to solve the given problems. Few learners employed one or two appropriate strategies in solving the problems. The strategies used by the learners to solve the algebraic word problems in the test include Computing or Simplifying (CS); Making a Table, Chart, or List (TCL); Making a model or a diagram (MD), and Guessing, Checking, and Revising (GCR). It is recommended that teachers model different strategies for solving mathematical problems for learners while teaching mathematics.

Black on Both Sides
Authors: Widener Danny 
Published: August 2024

This article explores the emergence and development of organizing around Blackness in Mexico. It offers an excavation of recent political history that culminated with the achievement of federal recognition of Afromexican identity by the Mexican state. The focus is on political gatherings and processes, although some mention of cultural work is made as well. Specific attention is given to the controversial presence of people of African descent from outside Mexico, assessing their contribution to the larger process of Black organizing within the country. I argue that these organizers played a key role in helping local activists devise what one scholar, writing in another context, has described as a “common grammar” of social experience that connected disparate villages throughout Mexico with the wider African diaspora. At the same time, the article offers an overview and assessment of the organizational forms and goals of Black organizations in Mexico. Here, questions regarding terminologies of self-definition, political interventions within the wider national context, the role of cultural activity, and the relationship between Black and Indigenous mobilization are all taken up.

“Frankstown Was the World with a Big W”: Pittsburgh and Beyond, an Interview with John Edgar Wideman
Authors: Kamali Leila 
Published: August 2024

On Friday, October 18, 2019, I conducted an interview with John Edgar Wideman at his home in New York City. The conversation was incredibly rich, John being very generous indeed with his memories and his profound insights. Our first focus was Pittsburgh itself—what a joy to hear him speak about the Homewood of his childhood, about something like a lost world. We discussed basketball, the languages of his childhood, and origin stories; as the conversation progressed, John reflected poignantly on what he sees as the cost of his success, that he is pushed ahead as a token while very little of his privilege is afforded to his own community.
He also had much to say about a driving quality of shame that he has experienced on a number of occasions in his life—in being shamed by a white classmate for not knowing more about Black music, and the related shame of not knowing much Black literature, and how that motivated him to establish the African American Studies program at the University of Pennsylvania. We discussed the expansion of his intellectual and cultural horizons that came with the experience of being a Rhodes Scholar at Oxford. The interview concluded with a sense of the awe with which the author regards his brother as well as his son, who have retained their humanity in spite of the greatest odds, and a reflection on the role of creativity in accomplishing such a feat.
East Pittsburgh: White Supremacy, Radical Relationships, and Chosen Family
Authors: Conti Norman 
Published: August 2024

This piece is a follow-up to “Stanton Heights” (Kalfou 5, no. 2 [2018]: 372–393), further considering the learning that takes place at the nexus of policing and the Black community. Specifically, it continues the stories of Leon Ford, a Black teenager shot and paralyzed by a Pittsburgh police officer; the murder of three Pittsburgh police officers by a deranged white supremacist; and Ralph Malakki Bolden, a genius-level intellect and remarkable peacemaker originally sentenced to death for the execution of a gun store owner and attempted murder of the store’s employee in an effort to secure weapons for defending his community against rival gangs. On their surfaces, the circumstances of these men would seem unrelated, but as the narrative plays out, unexpected connections reveal an ever-widening circle of complicity. Additionally, this piece addresses the unwarranted police killing of local teenager Antwon Rose Jr. and the protests that followed.
