Self-Diffusion of Indium and Bismuth in Molten In0.5Bi0.5 Alloy at Different Thermodynamic State
Authors:  Kalam Md Abul , Ahmed  A Z Ziauddin , Rahman Muhammad Lutfor , Amin Muhammad Ruhul
Published: February 2025

This research work focuses on the theoretical study of atomic transport properties of molten In0.5Bi0.5 alloy at different thermodynamic states. Particularly, the self-diffusion coefficients (Di) of indium (In) and bismuth (Bi) in In0.5Bi0.5 alloy are explored by utilizing Distribution Function Method, which is based on the statistical mechanical theory. Inter-ionic interactions and pair distribution function are two main components of this method. The inter-ionic interactions are modeled by using local pseudopotential known as Brettonet-Silbert model, while the pair distribution function is derived by the Ascroft –Langreth theory. The effective hard sphere diameter is the main ingredient to calculate the Di, which is deduced from the thermodynamic perturbative theory called the Linearized Weeks-Chandler-Anderson method. The calculated results indicate that the value of Di for In agrees well with the available experimental data in the low temperature region.

Authors: Khaer M A , Hoq M A , Hassan S M Tabirul , Chowdhury M T , Rahman M M
Published: February 2025

From its commissioning, it was required to ensure the nuclear or radiological safety of the BAEC TRIGA Mark-II Research Reactor according to the country-specific regulatory guidance (BAERA) or followed by any international guidance (US NRC or IAEA). It is always important to take protective actions not to commit enough radiological doses. Therefore, the present work focused on the core inventory and radiological dose assessment due to a hypothesized research reactor accident of TRIGA Mark-II at Savar, Dhaka, Bangladesh. The core inventory and source term of five radionuclides (137Cs, 131I, 133Xe, 85mKr, and 90Sr) were studied using the ORIGEN 2.1 code until December 2021. These radionuclides were chosen due to their high emission characteristics from a nuclear accident.  The dose values of TED, ground deposition, and organs were calculated for an 80 km radius from the reactor site using the HotSpot 3.1.2 code and meteorological data of six seasons of Bangladesh. The assessed dose values are compared and it is shown that dose values in the rainy season are highest due to the rainout coefficient. The other five seasonal TEDE data show similar dose patterns and are also high enough to the permissible limit of dose values. So, regardless of the time of year, if an accident occurs, it is necessary to immediately take preventive radiological measures based on the local authority emergency response plan.

The Mechanics of a Pedestrian Run Over by A Motor Vehicle
Authors: Otte Dietmar
Published: February 2025

In road accidents, there are frequently incidents in which a person is hit by a vehicle and then run over or people who are lying on the road who are run over (without prior collision). Chest injuries are the most severe injuries, especially intrathoracic organ injuries; these are caused by a wheel rolling over the body. For the safety development of cars, these events are very rare (< 0.1 %) and therefore do not require mandatory measures. However, these incidents are often processed with forensic expertise. In this respect, knowledge of kinematics, mechanics and injury analysis are important.

In 1975, the author wrote a diploma thesis that deals with the detailed technical mechanism of running over a person lying on the road; this work has not been published to date. Nevertheless, there have been repeated individual enquiries prompting the need for publication at the present time.

The body of the pedestrian must be seen in mechanical strength as a rectangular compressible body with varying stiffness and flexible body segments. Characteristic end positions and distance-time correlations were found in the tests when the vehicle was run over at speeds of 30 and 50 kph. The most important influencing factor can be considered to be the crossing point on the body. The maximum movement of the body in driving direction of the wheel occurred when the thorax was run over and was significantly greater compared to when the head was run over; it was also greater with a braking wheel than with an unbraked wheel.

Effect of Gas Pressure on the Oxidation Behavior of Cu and Cu Alloys
Authors: Park Jun Sang , Kim Doo-won , Jeong Il-Seok , Choi Eun-Ae , Kwon Se Hun , Han Seung Zeon
Published: February 2025

This study investigated the effect of gas pressure and alloying elements on the oxidation behavior of copper. Copper alloys containing 1 wt.% of zinc, nickel, or manganese were cast using vacuum induction melting, followed by solution treatment at 400°C for 60 minutes. Oxidation were conducted at 700°C for 60 minutes under pressures of 101325, 20, and 10 Pa. The oxide layers formed at atmospheric pressure on both the pure copper and copper alloys naturally delaminated. In contrast, the oxide layers formed under low-pressure conditions remained intact without delamination. This improved bonding strength between the copper matrix and Cu2O was attributed to the formation of large grains and dense oxide layer, which increased the contact area with the copper substrate. Additionally, the oxide layers formed under low-pressure exhibited higher dislocation density, which reduced lattice mismatch and interface energy, thereby contributing to the formation of stable interface. In copper alloys, thicker oxide layers were observed compared to pure copper, with voids detected between the oxide layer and the copper substrate. These voids were presumed to be Kirkendall voids, resulting from the difference in diffusion rates between copper and the alloying elements. However, adhesion evaluations indicated that these voids did not significantly impact interfacial adhesion. Through interface control, dense and stable oxide layers were successfully formed on both pure copper and copper alloys.

Our research targets Syrian refugee families dealing with the economic aftermath of the COVID-19 pandemic, including the resulting social tensions and a recovering education system. We explore the experiences of teachers, facilitators, and caregivers in order to identify the key factors that contributed to the two programs' success. Data from 71 postintervention interviews and 9 focus groups conducted in July 2022 and January 2023 reveal that remote programs are viable in contexts with limited in-person access. Despite some challenges, both teachers and caregivers demonstrated their adaptability and commitment. Flexible programming that accommodated family schedules proved essential. The caregivers' engagement was driven by their recognition of the programs' value and embracing of play-based learning. Using Weisner's (2002) ecocultural framework, the study challenges the notion that education programs must align with family routines. It presents evidence from the Ahlan Simsim intervention that this program can have a positive effect, even in the absence of established daily routines. The study highlights the importance of program design, teacher training, and collaboration in meeting families' diverse needs, which has implications for creating flexible, engaging, remote early childhood education programs.

Support to improve teacher wellbeing is scarce in almost all contexts, but especially so in low- and middle-income settings in which teachers face both professional and personal challenges (Kirk and Winthrop 2007; Mendenhall, Gomez, and Varni 2018). In this field note, we discuss War Child's development of Coaching-Observing-Reflecting-Engaging (CORE) for Teachers, an intervention that focuses on improving teachers' wellbeing. CORE is grounded in acceptance and commitment therapy and in the social-emotional framework of the Collaborative for Academic, Social, and Emotional Learning. It also draws from current research, including Jennings and Greenberg's (2009) prosocial classroom model. CORE aims to have a positive influence on classroom climate by providing teachers with the skills and knowledge they need to create an enabling, impactful, and safe learning environment for their students. In this field note, we outline the background on the development of the CORE intervention, including a literature review, the development of a theory of change, and field testing conducted in Chocó, Colombia. Having been field tested and adapted, CORE now is ready for further studies to determine feasibility and effectiveness.
Collaborative Online International Learning (COIL) at a Community College
Authors: Chang Helen
Published: February 2025

Collaborative Online International Learning (COIL) is a form of virtual exchange that connects a U.S. based class with a class at a college or university outside the U.S. Students from each class work together on one or various assignments in bi-national teams for several weeks during the semester. At a community college like Hostos College, CUNY, where students have few options to study abroad, COIL provides a structured opportunity to engage with peers in other countries, especially with students at 4-year institutions. Evaluating my COIL experience highlighted the need for open education resources (OER) not only in the project material but also the project itself as well as the importance of communication and partnership with a 4-year institution. I present the OER resources produced as well as preliminary student data that show some indications that the goals of virtual exchange were achieved.

Published: February 2025

Introduction

Experts have a well-established consensus regarding the detrimental effects of human activities on the environment, including extreme temperature events, rainfall variability, pollution, deforestation, biodiversity loss, and flood occurrences—all of which significantly stress Earth’s natural systems. This study investigates the level of environmental concern among university students in Bangladesh, considering their socio-demographic factors.

Methods

A comprehensive survey was conducted using a self-administered questionnaire targeting 380 final-year bachelor and master’s students from various academic disciplines at Shahjalal University of Science and Technology (SUST) Sylhet, Bangladesh. The analysis involved variables such as gender, completion of university courses related to the environment or climate change, disciplinary background, and vulnerability to climate change or extreme weather events in their home locality. Relationships between these variables and the students’ environmental concerns were examined using cross-tabulation with the Chi-square test and mean difference with the ANOVA test.

Results

The findings indicate a high level of knowledge and significant concern among students regarding environmental issues, with disciplinary background being the primary determinant of environmental concern level. Additionally, completing university courses on environmental or climate change topics and experiencing vulnerability to such events in one’s hometown are significant predictors of environmental concerns.

Discussion

This study highlights the growing environmental concerns among university students and underscores the need for further scientific research to comprehensively understand their impact on population dynamics.
The portrayal in the Spanish press of migration caused by climate change: a moral framework analysis
Authors: Prieto-Andrés Antonio , Fernández-Romero Cayetano , Aguareles Marina
Published: February 2025

This study analyzes how migrations due to climate change and environmental causes are represented in the leading Spanish newspapers, but from a novel perspective, linking variables such as the topics that are covered the most or the most commonly used news sources to the typology of moral frames applied. This typology is based on the moral responsibility of the media when it comes to representing climate or environmental migrants. The methodology of quantitative content analysis, combined with framing theory, was used. The findings indicate that the Spanish press presents this issue from the perspective of the intellectual elite, seeking to analyze the phenomenon with rigor, relying on experts, and combining the coldness of the data with a good dose of empathy toward the migrants’ situation. With regard to the most common topics, the causes of this type of migration stand out, along with the legal issues affecting migrants. The predominant portrayal is of the migrant as a victim, but also as a political subject, with their portrayal as a threat remaining very limited, which is novel when compared with other studies, in which this aspect holds greater relevance. In terms of moral frameworks, the one in which migrants are viewed as a biological life is most prevalent (32.1%), followed by that of empathy (30%) and hospitality (25%), with the one that views migrants as a threat having largely fallen by the wayside (11.4%). This paper also analyzes the combinations of this framework with the mentioned variables to identify possible correlations.
Call for a consensual definition of dyslipidemia in coronary angiography trials

Dyslipidemia is extensively analyzed in clinical trials investigating its role as a risk factor for coronary artery disease (CAD). However, its definition varies vastly among studies, leading to different attributions to the variable dyslipidemia. The objectives of this study are to verify the hypothesis of a lack of a consensual definition of dyslipidemia in coronary angiography studies and to propose a consensual definition of dyslipidemia, considering the influence of each serum lipid parameter on mortality. A systematic search of coronary angiography studies focusing on dyslipidemia was conducted. We listed definitions and their references in the 258 articles the research found. Out of the 258 articles retrieved in the search, 52 studies (20%) provided a definition of dyslipidemia, and 20 (8%) mentioned the source. We identified 39 different definitions. To mitigate misinterpretations of cardiovascular risk factors, we propose the use of the “lipid triad” components to define dyslipidemia: LDL-cholesterol >3.0 mmol/L for primary prevention and >2.6 mmol/L or >1.4 mmol/L for secondary prevention in patients over/under 75 years old, respectively; or HDL-cholesterol <1.3 mmol/L (women) and <1.0 mmol/L (men); or triglycerides >1.7 mmol/L.
