This research paper attempts to investigate the organization and effectiveness of vocabulary notebooks by distinguishing several benefits the implementation of this technique brings in the acquisition of technical terminology through an "English for Specific Purposes course". When tackling with language learning, it is needless to emphasize the noteworthiness and the importance of vocabulary in this process. Appertaining to technical terminology, this plays entirely pertinent. Various studies have concluded that vocabulary notebooks (henceforth VN) efficiently expose different learners' strategies within this single strategy, which led us to research VN. These research data were obtained mainly by applying the observational research technique, a vocabulary oral and written exam, and a comprehensive questionnaire on the effectiveness of the Vocabulary Notebook. Mechanical Engineering, Textile Engineering, and Hydrotechnical Engineering students at the Polytechnic University of Tirana were selected to obtain the data. The observation is partly overt and partly covert. Students of Mechanical Engineering and Textile Engineering (75 students) are the treatment group wherein the Mechanical Engineering students are an overt group and the Textile Engineering students serve as the covert observational group while on the other hand, the Hydrotechnical Engineering (45 students) students are the control group. The data were obtained during and at the end of the semester. Throughout the observation all along the 1st semester, it was perceived that most of the students organized their VN by utilizing mainly Microsoft Word downloaded on their Smart Phones, while the rest used the traditional paper notebook to organize their technical VN. The organization of the VN reflected the strategies each of the students implemented to learn technical terminology. At the end, students were tested on their acquired terminology through an oral and a short-written exam and then a questionnaire was handed to them. The students of the overt group making use of a digitalized form of a Notebook resulted to have acquired most of the technical vocabulary. In the main, the overt group outperformed the covert group on the acquisition of technical vocabulary, while the control group's score on the oral exam was significantly below, compared to the all-inclusive treatment group. Students' questionnaire revealed that overall students had a positive approach to this strategy and they embraced the autonomy acquired throughout the semester by implementing this strategy. With the exception of the effectiveness on vocabulary acquisition, which was on higher levels, this strategy proved itself once again to be an enhancer and promoter of learner autonomy.

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.

The development of highly specific biomimetic recognition material is a challenge for rapid detection of harmful residues in foodstuff. In this study, a paper-based boronate affinity metal-organic framework/molecularly imprinted polymer microfluidic chip (FZS-BA@MIP) was constructed based on the in situ construction strategy, which was also designed as a highly specific biomimetic recognition module. Here, the homogeneous zeolitic imidazole framework-8 (ZIF-8) membrane served as a great scaffold and enrichment layer. Besides, the recognition layer of MIP was prepared based on a highly oriented boronate affinity surface imprinting strategy. With the aid of the liquid flow channel, the highly specific enrichment and visual detection for antibiotic residues like kanamycin in actual products were achieved on the paper chip module of an integrated lateral flow platform. The whole analysis process could be accomplished within 30 min. In brief, this study offered a new integrated biomimetic recognition platform for visually detecting harmful veterinary residues containing cis-diols, which demonstrated promising commercial value in point-of-care testing of foodborne hazardous compounds.

Engineers make things, make things work, and make things work better and easier. This kind of knowledge is crucial for innovation, and much of the explicit knowledge developed by engineers is embodied in scientific publications. In this paper, we analyze the evolution of publications and citations in engineering in a middle-income country such as Mexico. Using a database of all Mexican publications in Web of Science from 2004 to 2017, we explore the characteristics of publications that tend to have the greatest impact; this is the highest number of citations. Among the variables studied are the type of collaboration (no collaboration, domestic, bilateral, or multilateral), the number of coauthors and countries, controlling for a coauthor from the USA, and the affiliation institution of the Mexican author(s). Our results emphasize the overall importance of joint international efforts and suggest that publications with the highest number of citations are those with multinational collaboration (coauthors from three or more countries) and when one of the coauthors is from the USA. Another interesting result is that single-authored papers have had a higher impact than those written through domestic collaboration.

Understanding the use of English in the workplace is essential for developing effective English language education programs in Higher Education Institutions (HEIs). However, workplace language needs are still understudied, particularly in Vietnam. Therefore, this paper reports on part of a task-based needs analysis research project carried out by a Vietnamese university to improve its institutional English language education programs to effectively prepare students for employment. In particular, it investigates the tasks undertaken in English by professional engineers in the workplace and the relevance of English language education at HEIs for addressing those communicative needs. The data were collected using two parallel versions of a needs analysis questionnaire delivered to 291 professional engineers and 40 employers and backed up by interviews with 39 of the engineers. Results identify 30 workplace tasks that professional engineers frequently dealt with in English, indicating a discrepancy between those identified workplace requirements and the English language training at HEIs, and providing practical suggestions to improve engineering students' readiness for employment. This paper provides useful information for researchers and practitioners interested in improving the effectiveness of English language education for professional purposes at HEIs in Vietnam and possibly across the Asia-Pacific region.

The integration of online platforms in (bio)chemical engineering education has increasingly become a matter of fact at all educational levels. Examples such as virtual laboratories in tertiary education have shown their benefits, such as the decreased cost and resources needed as well as providing a safer environment for practical experimentation. However, students or stakeholders are not usually involved in developing the virtual laboratory, even if, when given the opportunity, they can provide valuable feedback for improvement and acquire ownership over the platform. Hence, when proposing a novel educational process virtual laboratory that targets teaching bioprocess modeling to undergraduate students, the best approach is to involve the students in the development as its future users. To this end, in this work, four co-participatory design experiences are presented that show the journey from a paper prototype to an online educational virtual laboratory (www.biovl.com). Qualitative and quantitative data have been collected in two different universities through surveys, semi-structured interviews, and informal conversations among the students and the developer. The students’ perspectives were found to provide valuable feedback about the platform’s content, usability, and functionality. For example, interest in adding bioprocess-related coding activities, or suggesting to change the platform name, were opinions collected and carefully considered. These suggestions can be easily integrated since the software is at the early stages of the virtual laboratory prototype. Although the usability and functionality features of the platform are under continuous advancement, this work’s findings show that the students are interested in contributing to the virtual laboratory’s development. Therefore, it opens the door to modifications and improvements, which are strongly based on the users’/students’ perceptions and perspectives as the virtual laboratory’s co-designers. Although the primary target of the BioVL prototype is to teach bioprocessing modelling, several advanced tools such as virtual and augmented reality (VR and AR) are being considered to be included at a future stage. Furthermore, the educational strategy proposed in this work can be replicated by those who want to develop other virtual laboratories.

In order to obtain stable and reliable configuration transformation ability, reliability optimization design is regarded as an effective way to reduce the probability of kinematic function failure for the constrained metamorphic mechanism. Based on the structural composition principle of multi-configuration source metamorphic mechanism that can operate in an under-actuated state, the modularized calculation methods are established for the force analysis of augmented Assur groups including metamorphic kinematic joints. According to the equivalent resistance gradient model of metamorphic mechanisms, with considering the uncertainties in the link dimensions, masses, and compliance parameters et al., a probabilistic evaluation method for describing the configuration transformation ability of the constrained metamorphic mechanism is established. Based on reliability evaluation and reliability sensitivity analysis, a reliability optimization design method for improving the configuration transformation ability is proposed, and then the optimization design is carried out for tolerances of random variables focusing on those structural parameters with higher reliability sensitivity, so that the optimized results can satisfy the requirements of both reliability and economic simultaneously. Finally, the feasibility and effectiveness of the proposed method is verified by the illustration of a paper folding metamorphic mechanism. The research provides the foundation of reliability design of metamorphic mechanisms to obtain the high-probability repeated execution ability of configuration transformation, it also has theoretical and practical significance to promote the engineering application of metamorphic mechanisms.
