The structure of the conclusion sections in Research Papers (RPs) is of significance in academic writing. The conclusion section in spite of providing an outline of the article, states other essential components, such as recommendations, implications and statements of possible lines of future research. This paper analyses the conclusion parts of Persian and English Research papers published in international journals. To meet this end 20 RPs were selected from two fields including Civil Engineering and Applied Linguistics. The Conclusion sections of the papers were examined for their moves based on Yang and Allison's (2003) model of moves. The frequency analysis of the moves showed slight differences among the moves employed and with regards to the Chi-Square tests, no significant differences were observed between the Conclusion sections of Applied Linguistics and Civil Engineering RPs regarding the moves employed as well as between Persian and English RPs. The study yields a richer understanding of the conclusion structure of research articles and offers ESP/EFL instructors and researchers insights which can be used in the instruction of the conventions or expectations of academic writing. Novice writers and non-native students can benefit from it, mainly because it helps them eliminate their writing dilemmas and assists them to take part in international discourse communities.

Industrial process heat decarbonization through electrification could contribute significantly to climate change mitigation efforts. In the US industry, thermal processes accounted for more than two-thirds of the total final energy demand in 2021. Cross-cutting electrification technologies like industrial heat pumps are suitable for the process heat supply to several industrial unit operations in a sustainable way while also improving overall energy efficiency. This study employs a bottom-up approach to investigate the techno-enviro-economic potentials of deploying high-temperature and steam-generating heat pumps in US textile, pulp and paper, and automotive sectors in different timeframes. The results show that the annual technical potential energy and CO2 savings by electrifying heat supply are 310 PJ (or 36% of the projected energy demand) and 28 MtCO2 (or 71% of the projected CO2 emissions) in 2050 respectively, however, these incur additional costs in each sector (ranging between 5 and 18 $/GJ). The required heating capacity of industrial heat pumps is estimated at 15 GW, which translates roughly into a market of over 6000 heat pump units and an investment volume of $7 billion in the studied processes. Although there may be individual cost-effective opportunities for electrifying heat supply in specific industrial sites, the overall costs are estimated to be high in the three industrial sectors due to the large disparity between electricity and natural gas prices and low heat source temperatures. To overcome the identified techno-economic barriers, comprehensive action plans for different stakeholders are also given. This study provides novel insights that should inform policymakers’ and executives’ decisions about the electrification of the current and future US industrial heat supply in relevant industrial sectors.

This paper investigates the use of commonly employed technologies in education across East African countries, specifically focusing on Tanzania, Kenya, Uganda, Rwanda, and Sudan. It draws on Google Scholar to identify key technologies used in teaching and learning, emphasizing their benefits, such as increased student engagement, commitment, interaction, and improved performance. However, several challenges hinder the effective use of these technologies, including unfamiliarity, time constraints, negative attitudes, lack of human resources, insufficient government support, and infrastructure limitations. To overcome these obstacles, the paper recommends providing teachers with better training and workshops on accessing and utilizing appropriate technological tools. Furthermore, it calls for enhanced government involvement to ensure modern technologies are effectively integrated, thereby improving the overall quality of education in the region.

Within the Master's course "Civil Engineering" at TU Darmstadt, a project has to be carried out. In the winter term 2018/2019 this was the design and fabrication of a bridge spanning 6 m and made entirely from paper. Students had to find bridge types suitable for the use of paper, develop and optimise cross sections and bracing systems and furthermore prove the load bearing capacity. This included the use of experimental methods explicitly. Finally, the bridge had to be erected crossing a small creek. No materials other than paper, cardboard and glue were allowed.

This study examines the use of lexical bundles in reports produced by university-level L2 English writers in civil and environmental engineering (CEE). The corpus consists of 119 reports, and the study compares the use of different types of lexical bundles (3-word, 4-word, and 5-word) in high-scoring and low-scoring papers. The results show that high-scoring papers use a wider range of lexical bundles, and that the use of lexical bundles varies by discipline. The study also identifies specific features of the lexical bundles that contribute to score differences. The findings suggest that teaching lexical bundles and vocabulary can improve the academic writing of engineering students. The paper concludes by calling for further research on the impact of formulaic expressions on attainment scores in L2 writing.

For shaped charge blasting projects in mining, civil engineering, and similar fields, it is proposed to modify the charge structure by combining slotted tubes and shaped charge liners to obtain a new type of charge structure. This aims to achieve directional rock breaking through the focused action of the shaped charge. The influence of different slotted pipe materials on the directional rock-breaking effect of concentrated energy using a new charge structure is explored through theoretical analysis combined with model test study, high-speed camera, stress–strain gauge, and other equipment. A comparison is made between slotted pipes made of aluminum, kraft paper, and PVC, with the cutting width of 2 mm. Based on the characteristics of the cracks formed after blasting, the new charge structure made of aluminum slotted pipe produces a penetrating crack that is almost consistent with the pre-cracking direction. Based on the corresponding characteristics of successively released blasting energy, the guiding and convergence effect of the new charge structure made of aluminum slotted pipe on the explosion energy is greater than that of the new charge structure made of the other two types of slotted pipe material. According to the strain data measured after blasting, the peak arrival time of the strain peak in the direction of the slotted pipe on one side of the shaped hood is shorter than that in the other two directions, and the peak strain is greater than that in the other two directions while having a better energy gathering effect. Based on the findings, the new charge structure with directional energy concentration has a damage reduction effect. Furthermore, the material of aluminum slotted pipe is found to be better than PVC slotted pipe, whereas the material of PVC slotted pipe is better than kraft paper slotted pipe in achieving directional rock breaking.

This study evaluates the effect of treated and untreated jute fiber/eggshell particulate reinforced cement-paper matrix composites for ceiling board application. Treated jute fiber (TJF) was obtained by immersing untreated jute fiber (UJF) into 1.25 M sodium hydroxide (NaOH) solution in a shaker water bath maintained at 40 °C for 4 h. Eggshells (ESP) were pulverized and sieved to -75μm. Samples were prepared by varying the fiber volume fraction from 0.5 to 2.5 wt.% in the composites. While other constituents such as the binder (cement) and eggshell were kept constant. An hydraulic press cold compaction molder was utilized in the production of the hybrid composites in a predetermined mix ratio designed based on previous research. The samples produced were cured for 7 and 14 days, then sundried for 36 h. The physical, thermal, mechanical and wear behaviour of the produced composites were evaluated while the surface morphology of the fractured splitting tensile samples were analyzed. The result reveals that TJF/ESP hybrid composites had better performance than UJF/ESP hybrid composites in most of the tests carried out. Increase in the number of curing days was found to also enhance the properties of the composite produced in majority of the test evaluated. The 0.5 wt.% UJF/ESP gave the least performance of all the composites developed. While 2.5 wt. % TJF/ESP showed an optimum properties among the composites tested. When compared with standard, it is concluded that the hybrid composites developed can be suitable for ceiling boards and also find possible application in wall partitioning.

In the final manuscript [[33]], presented as a communication, the author indicates that unmanned aircraft systems (UASs), commonly referred to as drones, are an emerging technology that has changed the way that many industries conduct business. When used on a state-by-state basis, the normalized UAS adoption index shows that there are regional differences in UAS adoption, with western and eastern states having higher UAS adoption rates and central states having significantly lower UAS adoption rates. The aim of this second I Eng i Special Issue is to collect experimental and theoretical re-search relating to engineering science and technology. Telecommunication companies collect a deluge of subscriber data without retrieving substantial information. [Extracted from the article]

Research-based practical applications are becoming increasingly important in providing valuable solutions to the challenges facing the construction industry. In this paper, we present a teaching concept that was implemented and evaluated in four courses, addressing the development of future-proof academic skills, particularly scientific working skills, in the field of civil engineering. The first evaluation results from a survey among the students who participated in the four courses are presented on the extent to which project-based and researchbased learning promote domain competences, planning, and study skills. The results indicate that, especially in master's degree courses, future skills are improved by paper-based learning. Additionally, student motivation increases due to the boost in creativity and group work facilitated by the teaching concept. On the other hand, the results suggest that guidelines are necessary to implement paper-based learning, especially in bachelor's degree courses. Furthermore, it is crucial that future-proof academic skills are relevant for success in the practical working context. [ABSTRACT FROM AUTHOR]

In civil and construction engineering education research, a focus has been on using 3D models to support students' design comprehension. Despite this trend, the predominant mode of design communication in the industry relies on 2D plans and specifications, which typically supersede other modes of communication. Rather than focusing on the presentation of less common 3D content as an input to support students' understanding of a design, this paper explores more common 2D inputs, but compares different visualization formats of student output in two educational interventions. In the first intervention, students document a construction sequence for wood-framed elements in a 2D worksheet format. In the second, students work with the same wood-framed design, but document their sequence through an augmented reality (AR) format where their physical interactions move full-scale virtual elements as if they were physically constructing the wood frame. Student approaches and performance were analyzed using qualitative attribute coding of video, audio, and written documentation of the student experience. Overall, results showed that the 2D worksheet format was simple to implement and was not mentally demanding to complete, but often corresponded with a lack of critical checks and a lack of mistake recognition from the students. The AR approach challenged students more in terms of cognitive load and completion rates but showed the potential for facilitating mistake recognition and self-remediation through visualization. These results suggest that when students are tasked with conceptualizing construction sequences from 2D documentation, the cognitive challenges associated with documenting a sequence in AR may support their recognition of their own mistakes in ways that may not be effectively supported through 2D documentation as an output for documenting and planning a construction sequence. The results presented in this paper provide insights on student tendencies, behaviors, and perceptions related to defining construction sequences from 2D documentation in order for educators to make informed decisions regarding the use of similar learning activities to prepare their students for understanding the 2D design documents used in industry.

Jowitt's paper suggests that civil engineering systems engineers require an ethical imperative and a set of specific attributes. The ethics should include a broad understanding of value and values. Attributes of a successful systems-capable civil engineer are listed in a table stemming from an international workshop. They can be summed up in terms of ASK: Attitude, Skills and Knowledge.

This paper focuses on a two-year program with a Norwegian public sector project-based construction company, where action learning groups and critical incident technique were combined to enhance organizational learning. Project-based organizations typically face difficulties of 'project amnesia', as they fail to integrate learning from experience into organizational memory. In drawing lessons from experience, employees often focus on solving short-term problems with individual projects rather than contributing to medium- and longer-term organizational learning. The program that is the focus of this paper engaged newly-appointed engineers in action learning groups and trained them to use critical incident technique to gather and analyze information about recent projects undertaken by the company. The groups reported back their findings to colleagues in the program and to managers and senior executives in the company. Originally designed as an alternative to the traditional induction training for new employees, the program generated useful practical learning across the whole organization about project success factors. This paper explains how action learning and critical incident technique combined in this program to enhance individual, team and organizational learning, and argues that the synergies between these three processes should be explored in other contexts.

Minoritized students in civil engineering frequently experience subtle negative attitudes or biases based on their race and gender. These subtle attitudes and biases are known as microaggressions and are reasons for low self-efficacy and retention in civil engineering. Previous studies demonstrated the prevalence of microaggressions in engineering education but did not focus on capturing the spaces where these microaggressions occur, nor do they identify the targets and perpetrators within civil engineering education. The current paper proposes to answer: (1) Where do microaggressions occur in civil engineering and non-civil engineering programs? (2) Who are the targets and perpetrators of microaggressions? The study included 328 surveys with minoritized undergraduate engineering students who identified as Black, Latinx, Asian, and white females. We found that the most significant spaces where microaggressions occurred were classrooms and labs, followed by office hours, study groups, and internships. In terms of perpetrators, peers and teaching assistants were the most significant, followed by faculty. When comparing targets of microaggressions across race groups, white females reported experiencing microaggressions less frequently than Black, Latinx, and Asian students. Black students reported experiencing microaggressions more frequently than any other groups included in the study. Finally, there was no difference observed among civil engineering and non-civil engineering students or the two institutions (a historically Black college and university and a primarily white institution). These findings provide recommendations for targeting better policies to address microaggressions in civil engineering education.
