This study aims to investigate students’ common errors in Vietnamese-English translation. For the objectives, 70 first-year students at Foreign Trade University – Ho Chi Minh campus, were invited to participate in this study. To identify students’ errors in Vietnamese-English translation, the participants were asked to complete five weekly assignments. The results revealed that students made grammatical, lexical, and spelling errors. The causes of these observed errors were also indicated, which included the difference between English and Vietnamese, inadequate culture background, students’ insufficient linguistic competence in English language and Vietnamese language, lack of cultural background knowledge, students’ inappropriate translation strategies, interference of Vietnamese, misunderstanding, and students’ carelessness. In addition, some suggestions were offered in the light of the findings identified in the study to help students improve their translation ability.

The present study aims to investigate the possibility of domestic wastewater treatment using biological system combined with chemical-physical processes, including Upflow Sludge Blanket Filtration (USBF) technology and PolyAluminium Chloride (PAC). Experimental results showed that the added PAC content plays an essential role in improving the treatment efficiency and reached National Technical Regulation on domestic wastewater QCVN 14:2008/BTNMT (Column A). With Jar-test results, the optimal pH of 7.0 and the PAC dosage of 170 mg/L were recorded with the highest removal efficiencies for suspended solids and organic matter. In the modified USBF bioreactor, the findings illustrated the pollutant removal efficiencies such as Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), and Suspended Solids (SS) were equal to 96.2 ± 1.4%, 85.8 ± 4.4% and 99.3 ± 2.1%, respectively. The parameters of BOD5 and SS met QCVN 14:2008/BTNMT - Column A. In the future, this advanced filtration technology can be helpful for wastewater reclamation and reuse to cope with water scarcity.

This article provides a comprehensive review of ISBN codes, shedding light on their significance and outlining the process of generating a 13-digit ISBN check digit. ISBN codes (International Standard Book Number) play a crucial role in identifying and cataloging books, serving as a unique identifier for each publication.

This work presents a benchmarking study between Lagamine, an in-house developed finite element (FE) code, and COMSOL Multiphysics® (Comsol) commercial software in thermal analyses to investigate their capability in modeling complex manufacturing processes. For this purpose, two case studies, including a NAFEMS benchmark for heat transfer with convection and a Directed Energy Deposition (DED) of a bulk sample, were used as test cases. The simulation models using Lagamine and Comsol solvers for each case were described. The underlying algorithms and theories, as well as the soft-ware development, are investigated. The computational results indicate slight differ-ences between Lagamine and Comsol solutions in both case studies. For the NAFEMS test case, the results obtained with Comsol solver appear to be less dependent on the mesh size than those obtained with Lagamine. For the DED test case, within the chosen configurations of Lagamine and Comsol codes, the maximum difference in the highest peak temperatures obtained from the two codes is about 20%. From an engineering point of view, it is suggested to determine parameters of the FE model consistently with the selected FE code to provide the best match with experimental observations.

With the development of information technology and smart technology to meet the Industrial Revolution 4.0, and to meet life requirements. Automatic control devices require high-precision control quality. Therefore, in this paper, we focus on researching the Sliding mode controller to improve the control quality compared to the PID controller. First, the sliding mode control is designed using the Lyapunov algorithm. Next, the process of simulating the position signal of a DC motor with a PID controller is compared with a sliding mode control to prove the effectiveness of the proposed controller.

Thu Dau Mot University is one of the main public education institutions in the South-Eastern region of Vietnam. The vision of the university is to adopt innovative teaching methodologies to improve education quality and attract more students. Thu Dau Mot University envisions becoming a smart university as one of its long-term strategies in order to be aligned with the smart city orientation of Binh Duong province. The paper evaluates the potential of buiding Thu Dau Mot university model by SWOT analysis. It’s results will serve as a reference for Thu Dau Mot university’s leaders to identifying where are the strengths, the weakenesses, the opportunities and the threats in their process of smart university development. Finally, the paper has provided recommendations to Thu Dau Mot university for becoming a smart university.

This study only deals with the range of functions of speech acts that the English language may serve all with a view to raise teachers’ and students’ awareness of the roles that the communicative intentions, the utterance functions and the interactive context play in the acquisition of language in general and in develoing students’ communicative competence in particular. With the aims beforehand, the study tries to analyse and present speech acts and implications for teaching and learning these aspects effectively. With reference to speech acts and their linguistic functions in the English language, this study can serve as a reference material for those who are interested in carrying out more research in this field.

Van Phuc 2 General Hospital is one of the hospitals that is always concerned about environmental protection in medical checkups and treatment. However to affirm and enhance the prestige is a regional hospital in the region, step by step approaching the hospitals around the world. Therefore, the subject "Proposing solutions to remedy meaningful environmental aspects at Van Phuc 2 General Hospital" is important to building a sustainable hospital development image. The subject focuses on the plan to develop the environmental management system by ISO 14001: 2015 based on the current management status of the hospital By the 3P and 4T methods, the criteria and methods of analysis and field survey were identified, There were five Environmental aspects at the hospital by followings: smells, dust, exhaustion, wastewater, infectious waste, and clinic waste. In addition, the subject also establishes objectives, environmental criteria, planning, resource-building procedures, communication systems, document systems, etc., to complete the environmental management system by ISO 14001: 2015 for the hospital. At the same time make recommendations to help the hospital can complying with all requirements when building an Environmental Management System. Keywords: Environment; Environmental aspects, hospital, solution

The study was undertaken to compare the lead accumulation and removal of Dracaena sanderiana, Dracaena reflexa, and Dracaena deremensis on artificial lead solutions to apply plants in lead pollution treatment. The experiment consisted of 6 treatments corresponding to 3 investigated species of Dracaena. Each treatment was grown on 2 types of solution with Pb and without Pb used as control. The results indicated that the growth of D. sanderiana, D. reflexa, and D. deremensis was not affected at Pb concentrations of 100 ppm. All three plant species had the ability to absorb and accumulate Pb. In which D. sanderiana was a typical lead excluder because the lead concentration in roots (1952.14 mg/kg), shoots (221.78 mg/kg), and leaves (166.46 mg/kg) of the plants were the highest among the three plants tested. The most of lead accumulated in the root, and transportation of lead in D. sanderiana, D. reflexa, and D. deremensis from root to shoot was restricted. Besides, the highest % removal of Pb was found at D. sanderiana (93.16%) and the minimum of 66.77% at D. reflexa. D. sanderiana is the best choice among the three Dracaena species used for phytoremediation of lead contaminated wastewater.
